The Internet, which has had an impact on almost every facet of our lives. It has grown at a rapid pace and devices connecting to in direct proportion, in turn increasing the routing tables. The Location Identifier Separation Protocol (LISP) helps to reduce the burden in both enterprise routers and Internet routers without changing the hardware, which could cost more than implementing a new routing protocol. The LISP helps in reducing Border Gateway Protocol (BGP) routes as well as keeping devices connected to the Internet or network with less downtime. Implementation of the LISP in a simulator helps network engineers learn the upcoming protocol and design, and test the network.Thesis (M.S.)--Wichita State University, College of Engineering, Dept. of Electrical Engineering and Computer Science

Le protocole LISP (Locator/Identifier Separation Protocol) a été déposé en 2006 dans le but de résoudre les problèmes d’extensibilité de l’Internet. Ce protocole est basé sur le mécanisme de map-and-encap qui consiste à séparer une adresse IP en 2 éléments : le qui et le où. Une nouvelle entité réseau, le Mapping Distribution System (MDS) est alors nécessaire pour faire la réconciliation de ces deux éléments. Malgré le fait que le protocole LISP soit déjà standardisé par l’IETF, et déployé sur deux plateformes de tests, c’est toujours un protocole jeune, et il lui manque encore des métriques précises pour montrer toute son utilité sur de larges réseau. Dans ce papier, nous évaluons LISP selon trois aspects différents: • Les mesures sur le MDS. • Implémentation d’un outil de monitoring pour superviser le MDS. • L’évaluation des performances d’interconnexion sur l’internet legacy. • L’évaluation de la mobilité de LISPThe Locator/Identifier Separation Protocol (LISP) was proposed in 2006 to initially address Internet scalability issues. It is based on a map-and-encap mechanism to split the who and the where of the current IP addresses. To retrieve the association between them, a new network entity called the Mapping Distribution System (MDS) is introduced. Although LISP is currently under standardization in Internet Engineering Task Force (IETF) and is deployed in the wild by two testbeds at the same time, it is still young. It lacks the thorough measurement work to show its real performance in large-scale networks. In this dissertation, we assess LISP from these different aspects: • The measurements on the MDS. • Proposing a comprehensive monitor to supervise the MDS. • The assessment of LISP interworking performance with legacy Internet. • The evaluation of LISP mobility

Il traguardo più importante per la connettività wireless del futuro sarà sfruttare appieno le potenzialità offerte da tutte le interfacce di rete dei dispositivi mobili. Per questo motivo con ogni probabilità il multihoming sarà un requisito obbligatorio per quelle applicazioni che puntano a fornire la migliore esperienza utente nel loro utilizzo. Sinteticamente è possibile definire il multihoming come quel processo complesso per cui un end-host o un end-site ha molteplici punti di aggancio alla rete. Nella pratica, tuttavia, il multihoming si è rivelato difficile da implementare e ancor di più da ottimizzare.
Ad oggi infatti, il multihoming è lontano dall’essere considerato una feature standard nel network deployment nonostante anni di ricerche e di sviluppo nel settore, poiché il relativo supporto da parte dei protocolli è quasi sempre del tutto inadeguato.
Naturalmente anche per Android in quanto piattaforma mobile più usata al mondo, è di fondamentale importanza supportare il multihoming per ampliare lo spettro delle funzionalità offerte ai propri utenti. Dunque alla luce di ciò, in questa tesi espongo lo stato dell’arte del supporto al multihoming in Android mettendo a confronto diversi protocolli di rete e testando la soluzione che sembra essere in assoluto la più promettente: LISP.
Esaminato lo stato dell’arte dei protocolli con supporto al multihoming e l’architettura software di LISPmob per Android, l’obiettivo operativo principale di questa ricerca è duplice: a) testare il roaming seamless tra le varie interfacce di rete di un dispositivo Android, il che è appunto uno degli obiettivi del multihoming, attraverso LISPmob; e b) effettuare un ampio numero di test al fine di ottenere attraverso dati sperimentali alcuni importanti parametri relativi alle performance di LISP per capire quanto è realistica la possibilità da parte dell’utente finale di usarlo come efficace soluzione multihoming.

L'un des défis majeurs de l'évolution de l'architecture Internet est la définition d'une architecture protocolaire permettant d'améliorer le routage, et en particulier (i) conserver un système de routage gérable avec les technologies actuelles et futures c'est-à-dire, avec quelques millions d'états, (ii) offrir une architecture apte à faciliter la programmabilité du plan de transfert, (iii) proposer un système de routage évolutif pouvant être régulièrement optimisé avec uniquement les informations sur les flux actifs, (iv) fournir une séparation entre localisateurs et identificateurs pour la mobilité IP avancée, (v) faciliter un déploiement incrémental, (vi) mieux servir les services applicatifs "over-the-top". Le protocole LISP (\textit{Locator/Identifier Separation Protocol}) a été identifié comme l'un des protocoles émergents à cet égard. Dans son état actuel, il répond très bien aux besoins susmentionnés. Cependant, il subit des limitations lorsqu'il s'agit de prendre en compte la résilience et la capacité à réagir rapidement aux mises à jour de l'état du réseau. Ces inconvénients peuvent être compensés en améliorant l'architecture du plan de contrôle et ses algorithmes de routage. Dans cette thèse, nous proposons une nouvelle architecture réseau-système et expérimentons de nouvelles primitives de plan de contrôle, ainsi que d'algorithmes de diffusion des états, en testant son passage à l'échelle avec différentes conditions de réseau. Nous concevons et construisons d'abord un nœud de plan de données et de plan de contrôle LISP open source. Nous le comparons avec d'autres implémentations en montrant que notre implémentation atteint des performances adaptées aux vrais déploiements. Nous montrons comment notre implémentation a permis la mise en oeuvre d'une plateforme d'expérimentation à grande échelle, la plate-forme LISP-Lab, en opération aussi bien les fonctions de plan de transfert que les fonctions de plan de contrôle. En suite, nous proposons une nouvelle solution pour les migrations à chaud de machines virtuelles à travers des centres de données géographiquement répartis sur des réseaux IP étendus. Des tests dans un testbed réel connecté nativement à Internet montrent qu'avec notre approche, nous pouvons facilement atteindre des temps d'arrêt inférieurs à la seconde lors de la migration sur une grande échelle, même pour des clients très distants. En outre, nous avons étudié des protocoles d'optimisation de réseau multicouche, en particulier en relation avec le protocole MPTCP (Multipath Transport Control Protocol), auquel LISP peut offrir une diversité de chemins pour l’agrégation de bande passante, ainsi qu’une plus grande confidentialité et fiabilité des connexions. Bien que nous ne puissions bénéficier que de quelques nœuds de réseau superposés, nous avons pu évaluer expérimentalement nos propositions en montrant l'impact positif de notre solution, l'impact négatif des longs temps d'aller-rétour sur certains sous-flux MPTCP, et la forte corrélation entre le temps d'aller-retour différentiel et le débit. Enfin, nous avons travaillé sur une refonte du plan de contrôle de LISP afin d’améliorer son fonctionnement du à l'échelle d’Internet, en facilitant la coopération entre les systèmes de mapping LISP et en introduisant plus d'automatisation dans la procédure de fourniture de services de connectivité LISP. Nous croyons qu'une telle optimisation pourrait sensibiliser la communauté des fournisseurs de services, générant de nouvelles opportunités commerciales liées aux services de cartographie LISP et l'application de politiques d'ingénierie de trafic interdomaines avancées dans le but d'obtenir de meilleures garanties de qualité de serviceOne of the major challenges in the evolution of the Internet architecture is the definition of a protocol architecture that allows to solve the following major issues in Internet routing and traffic forwarding capabilities, (i) keeping a routing state that is manageable with current and forthcoming computing infrastructure – i.e., with few millions of states, (ii) offering a scalable pull architecture in support of data-plane programmability, (iii) offering a scalable forwarding plane able to be regularly optimized with only active flows information, (iv) offering locator/identifier separation for advanced IP mobility, (v) is incrementally deployable, (vi) can enhance the support of over-the-top services. The Locator/Identifier Separation Protocol (LISP) has been identified as one of the rising protocols in this respect. In its current status, it supports the above mentioned requirements at a level that is acceptable for basic networking environments. However, it shows too limited capacities when it comes to take into consideration fault resiliency and capability to react fast to network state updates. These shortcomings can be compensated by enhancing the control-plane architecture, and the routing algorithms therein. In this dissertation, we propose new protocol features and experiment novel control-plane primitives, as well as hybrid distributed-centralized routing state dissemination algorithms, to scale with different network conditions. We first design and build own open source LISP data-plane and control plane node, comparing it with other implementations, showing how our implementation can scale for large networks and reach performances suitable for real deployments. We present how our implementation served to operate all network nodes (data-plane and control-plane nodes) of a large scale experimentation testbed, the LISP-Lab testbed. Then we propose a novel LISP-based solution for VM live migrations across geographically separated datacenters over wide area IP networks. Experimenting it at large scale, we show that with our approach we can easily reach sub-second downtimes upon Internet-wide migration, even for very distant clients. Moreover, we investigate cross-layer network optimization protocols, in particular in relation with the Multipath Transport Control Protocol (MPTCP) to which LISP can deliver path diversity in support of bandwidth increase, confidentiality support and connection reliability, also using LISP traffic engineering network overlays. Despite we could benefit from only few overlay network nodes, we could experimentally evaluate our proposals showing the positive impact by using our solution, the negative impact of long round-trip times on some MPTCP subflows, and the strong correlation between the differential round-trip time among subflows and the throughput performance. Finally, we worked on a framework to improve LISP operation at the Internet scale, by facilitating cooperation between LISP Mapping Systems and introducing more automation in the LISP connectivity service delivery procedure. We believe such optimization could raise awareness among the service providers’ community, yielding new business opportunities related to LISP mapping services and the enforcement of advanced inter-domain traffic engineering policies for the sake of better quality of service guarantees

A iminente implantação do IPv6, pode ser uma solução para o crescente uso de dispositivos móveis, para ensejar a mobilidade e para solucionar problemas derivados do esgotamento de endereços IPv4. Contudo, para o provimento de mobilidade é necessário garantir conectividade ao usuário, permitindo uma utilização continuada de seus dispositivos quando em movimento, sem que ocorra a perda de conexão, de forma segura e transparente. Isto não é possível com a arquitetura TCP/IP atualmente implementada nas redes que estão operacionais, mesmo que utilizem o protocolo IPv6. Neste sentido, este trabalho visa estudar as propostas mais expressivas no provimento de mobilidade sobre IPv6, com vistas a evidenciar suas características e funcionalidades. Apresenta como resultado, uma análise desses protocolos, em especial no que tange ao tempo de troca de rede (handover) e facilidade de implementação.The imminent deployment of IPv6, may be a solution to the growing use of mobile devices, to bring mobility and to solve problems arising from the exhaustion of IPv4 addresses. However, to provide mobility is necessary ensure connectivity for the user, allowing continued use of their devices while on the move, without loss of connection, securely and transparently. This is not possible with the TCP/IP architecture currently deployed in networks that are operating, even if used the IPv6 protocol. Thus, this work aims to study the most significant proposals in the provision of mobile IPv6, in order to contrast their features and functionalities. Presents as result, an analysis of these protocols, especially with respect to time network exchange (handover) and ease of implementation.

Magister Curationis - McurClinical experiences have always been an integral part of nursing education, and the value thereof to the nursing students is widely demonstrated in research. The purpose of clinical supervision is bridging the gap between theory and practice and ensuring that nursing students are prepared to be competent in their professional duties upon completion of their studies. However, clinical supervision focuses mainly on clinical skills and seems to neglect policies and protocols that govern care delivery, often impacting negatively on the expected quality of service. This problem is more so prominent in policies and protocols pertaining to medication. The Essential Drug List (EDL), which is a useful tool in the South African public health facilities, is one such protocol. Supervision on Essential Drug List as a medication protocol seems to be non-existent in the nursing field despite the expectations that nursing students should be able to implement its contents upon completing their studies. The nursing students' views regarding supervision in this regard are often not sourced despite their importance as stakeholders. However, if positive changes that will serve as a solution to the current problem are to be achieved, the students need to be heard. The study aimed to explore the perceptions of nursing students at a university in the Western Cape regarding clinical supervision on EDL medication protocol.

Previous issue date: 2013-11-29Background: The current study aims to test and a vancomycin protocol based on the initial hemodialysis patients weight and to describe drug peak and through serum levels. Methods: A study enrolling 16 ESRD adult patients cohort undergoing hemodialysis received a uniform vancomycin administration schedule: 20 mg/kg initial dose, infused during the last dialysis hour; blood sample collection 30 minutes post-dialysis and, subsequently, before every dialysis session. Additionally, a fixed schedule to adjust every new dose was used. Anthropometric, clinical and laboratory variables were collected. Descriptive statistics was used; Spearman correlation coefficient was used to verify associations. Results: No significant correlation between vancomycin peak serum level and trough levels and the initial dose, nor any trough level and the following doses were uncovered. However, total serum protein strong and positively correlated with the initial Vancomycin dose and the first trough serum level (rs = 0.608, P = 0.016 and rs= 0.641; P = 0.010, respectively). Initial dose positively correlated with albumin too (rs= 0.572, P = 0.02). A strong correlation between the first and second trough levels was also found (rs = 0.608; P = 0.021). Conclusion: As applied, the vancomycin administration protocol was ineffective in reaching and maintaining therapeutic peak and trough levels. It is possible that a significant loss of vancomycin free-fraction by dialysis accounted for such a finding. Correlation of vancomycin serum levels between total serum proteins should be further investigated.

O medicamento foi administrado por infus?o intravenosa numa concentra??o de 10mg/mL na ?ltima hora da sess?o de hemodi?lise. O protocolo proposto baseia-se em doses administradas a cada sess?o de di?lise, realizadas tr?s vezes na semana, considerando o peso do paciente, uma dose inicial e define ajustes de dose a cada vancocinemia, com o objetivo de mant?-la nos n?veis terap?uticos estabelecidos de 10 a 20mg/L. Resultados: N?o houve correla??o significativa entre as concentra??es de vancomicina s?rica no pico e vales com as doses definidas pelo protocolo. Entretanto, o primeiro vale e as prote?nas plasm?ticas apresentaram forte correla??o positiva (rs = 0.608, P = 0.01), al?m da dose inicial tamb?m se correlacionar positivamente com as prote?nas plasm?ticas e albumina (rs = 0.641, P = 0.01 e rs= 0.572, P = 0.02). Os n?veis s?ricos de vancomicina entre o primeiro e o segundo vales apresentam forte correla??o positiva (rs = 0.608, P = 0.02) e o volume de distribui??o apresenta forte correla??o inversa ao valor de pico de vancomicina (rs = - 0.990; P < 0.001). Conclus?o Embora o estudo n?o tenha sido capaz de determinar um protocolo, identificamos uma variabilidade muito grande entre os resultados de vancocinemia. Doses mesmo ajustadas pelo peso seco do paciente e n?veis s?ricos de vancomicina n?o foram suficientes para manter os n?veis terap?uticos de vancomicina. ? poss?vel que haja perda significativa de vancomicina durante a hemodi?lise. A correla??o com as prote?nas plasm?ticas pode ser sugestiva quanto ? prote??o na remo??o durante a di?lise, por?m necessita ser investigada.

Research guides the parameters for assessment and treatment of individuals with cleft lip and/or palate (CL/P). Most developing countries cannot provide an adequate standard of cleft care, due to limited resources. Speech-language therapists and audiologists in developing countries can contribute to improving cleft care through early communication intervention to minimise/prevent the negative impact of a cleft on a young child’s communication ability and to support the families. However, they require linguistically and contextually relevant assessment instruments for early identification of communication disorders in these children. The aim of the research was to develop and evaluate a communication assessment protocol for young children with CL/P, for use in Mauritius, a developing country in the Indian Ocean with a multilingual and multicultural population. A further aim was to develop an electronic database of children with CL/P in the public health sector of Mauritius. Eighty-eight children, with CL/P, 0-6 years, were selected by consecutive sampling and their parents acted as participants. Four speech-language therapists and audiologists from the public health sector of Mauritius participated in the data collection and appraisal of the newly developed assessment protocol. A mixed methods research design was selected. Based on exploratory research of cleft care in Mauritius and international recommendations for assessment of young children with CL/P, a comprehensive Communication Assessment Protocol was compiled and speech elicitation materials in Creole and French were prepared. Speech-language therapists and audiologists conducted assessments, using non-invasive procedures to assess feeding, hearing, communication skills development, emergent literacy skills, speech production and voice of the participants. Digital video and audio recordings of the elicited speech samples were made and auditory-perceptual procedures for speech analysis and inter-rater comparisons for reliability were employed. The communication assessment protocol was useful in describing the characteristics of the children with CL/P treated in the National Health System in Mauritius. The speech-language therapists and audiologists together with the parents of the children as partners in assessment were successful in early identification of communication delays/disorders in children with CL/P (73%) and also referrals to other health care professionals. The protocol was evaluated and accepted for application in clinical practice. The newly developed Communication Assessment Protocol was applied by local speech-language therapists and audiologists with the possibility of implementing this assessment instrument nationally. This was an important contribution to improve cleft care in Mauritius where interdisciplinary team-based cleft care has not occurred to date.Thesis (DPhil)--University of Pretoria, 2010.

Previous issue date: 2008-11-24Nowadays, the use of the wireless network technology has grown mainly motivated by the price of equipments, ease of installation, network maintenance and expansion of technical safety. The more you use the wireless network resource, the better should be the treatment related to its safety aspect. As the security level increases, the amount of information transmitted between the equipment decreases. This thesis aims to analyze the performance of WLAN network with the implementation of WEP and WPA / TKIP security protocols in an environment that uses applications whose characteristic is to generate small packets on the network. The LanTraffic TM software is used to generate traffic and also to capture the transmission rate in Kbps that flows through the stations. Three scenarios are simulated varying in the distance between the equipments. For each scenario, a comparative study was made and the WLAN behavior without the security resource analyzed, then it was analyzed with the WEP fitted and finally with the WPA/TKIP configured. To develop the experiments it was used a WLAN network in a controlled environment in the Laboratory Research on Radio System in PUC Campinas. Therefore, there is not external interference in the signal transmitted by equipments.
A utiliza??o da tecnologia de rede sem fio tem crescido ultimamente motivado principalmente pelo pre?o dos equipamentos, facilidade de instala??o, manuten??o da rede e amplia??o das t?cnicas de seguran?a. Quanto mais se utiliza o recurso de rede sem fio maior tem de ser o tratamento em rela??o ao aspecto de seguran?a. A medida que aumenta o n?vel de seguran?a, decresce a quantidade de informa??o transmitida entre os equipamentos. Esse trabalho visa analisar o desempenho de rede WLAN(Wireless Local ?rea Network) com a implementa??o dos protocolos de seguran?a WEP(Wired Equivalent Privacy) e WPA/TKIP(WI-FI Protected Access / Temporal Key Integrity Protocol). ? utilizado o software LanTrafficTM para gerar tr?fego na rede e tamb?m para capturar a taxa de transmiss?o em Kbps trafegados entre as STAs. S?o emulados tr?s cen?rios variando a dist?ncia entre os equipamentos. Para cada cen?rio foi confeccionado um comparativo e analisado o comportamento da WLAN configurado sem seguran?a, com o WEP habilitado e finalmente com o WPA/TKIP configurado. Para executar os experimentos utilizou-se uma rede WLAN no laborat?rio de pesquisa em sistema de r?dio (LP-SiRa) da PUC Campinas em um ambiente controlado. Com isso n?o h? interfer?ncias na transmiss?o dos sinais emitidos pelos equipamentos Ou seja, sem interfer?ncia externa no sinal transmitido entre os equipamentos.

Previous issue date: 2009-06-07This work presents a packet manipulation tool developed to realize tests in industrial devices that implements TCP/IP-based communication protocols. The tool was developed in Python programming language, as a Scapy extension. This tool, named IndPM- Industrial Packet Manipulator, can realize vulnerability tests in devices of industrial networks, industrial protocol compliance tests, receive server replies and utilize the Python interpreter to build tests. The Modbus/TCP protocol was implemented as proof-of-concept. The DNP3 over TCP protocol was also implemented but tests could not be realized because of the lack of resources. The IndPM results with Modbus/TCP protocol show some implementation faults in a Programmable Logic Controller communication module frequently utilized in automation companies

Obiettivo ultimo di questa tesi è fornire le competenze necessarie per poter capire come effettuare politiche di filtraggio dei contenuti fruibili su Internet in contesti prevalentemente di network locali come LAN aziendali ma anche su scala maggiore, effettuando politiche di blocco al livello logico 7 della pila protocollare ISO/OSI.
Nello specifico verranno approfondite le specifiche tecniche del protocollo SSL/TLS e su queste basi teoriche verranno implementate e testate regole di blocco di specifici servizi Internet simulando il contesto di una piccola rete domestica con un Firewall di frontiera posto davanti al gateway della rete locale che funge da filtro per la comunicazione con la rete Internet.
Verranno inoltre esposte delle problematiche direttamente correlate a quella che è l'infrastruttura giuridica fisicamente costruita intorno all'accertamento dell'identità digitale degli enti/soggetti all'interno di comunicazioni che sfruttano le funzionalità del protocollo SSL/TLS come strumento per criptare i dati ed avere garanzia sull'identità che si cela sul lato Server della comunicazione, trattando nello specifico alcuni casi storici di brecce informatiche all'interno delle infrastrutture fisiche dei Certificate Authorities, enti predisposti al ruolo di certificatori delle identità digitali sopracitate, o dell'uso improprio da parte loro del potere conferitogli, saranno inoltre esposti e replicati su scala minore esempi di come alcuni enti governativi nazionali sfruttano alcune caratteristiche intrinseche di questo protocollo per bloccare determinati servizi all'interno della sottorete Internet da loro gestita e di come in un contesto storico nel quale venisse a mancare il caposaldo della Network Neutrality, proprio quelle specifiche protocollari potrebbero essere utilizzate per effettuare politiche di gestione prioritaria nell'instradamento dei pacchetti all'interno della rete Internet.

INTRODUCTION: Colostrum therapy, also called oral immunological therapy, is the administration of colostrum via the oropharyngeal route to preterm infants and can be started within the first six hours of life. Small doses of colostrum are administered to the oral mucosa and upper respiratory tract of the infant, which may exert a protective effect on the mucosal membrane. In addition, immunoglobulin A, colostrum cytokines, antioxidant agents and all anti-infective agents may interact with lymphoid cells within the oropharynx, stimulating the infant's immune function. Recently, studies have reported the importance of colostrum administered by the oropharyngeal route, especially for extremely low birth weight preterm infants, with nutritional and immune defense effects already demonstrated. The more premature the baby, the more it will benefit from early exposure to colostrum. OBJECTIVE: To estimate the success rate after implantation of a colostrum administration protocol in low birth weight preterm infants at the Hospital Sa?de, in Caxias do Sul, RS. METHODOLOGY: The study took place between March and July 2017, after the ethical approval of the project. The participants were 41 mother / baby pairs whose mothers, after signing the free and informed consent, made attempts to exhaust the breast to provide colostrum to their children. Preterm infants between 24 and 32 weeks of age who had an indication of colostrum therapy prescribed by the physician were included, and attempts were made to exhaust the breast before six hours of the newborn's life. Two data collection instruments created by the researcher were used, one with information about mothers and newborns and the other for the Neonatal Intensive Care Unit nursing team to respond. After the observation of the attempt to obtain the colostrum, the questions of the collection instrument were considered, as if the puerpera managed to exhaust 0.2 mL of colostrum or not, or if the breast was exhausted before six hours. Through the charts of each baby, the data on administration were collected. It was observed if there was a decrease in oxygen saturation and / or an increase in respiratory and cardiac frequencies at the time of administration of colostrum. The success of colostrum therapy was considered to be the administration of at least one dose of colostrum within the first 72 hours of life, and the success rate was reported as a percentage of the cases that were successful among all included. RESULTS: Among the 41 premature infants included in the protocol, 19 (46.3%) received at least one dose of colostrum within the first 72 hours of life and 22 (53.7%) did not receive colostrum. There was an association between being able to deplete the breast earlier and the baby to be able to receive colostrum, regardless of when it was received. All 22 cases of colostrum failure were due to failure to obtain colostrum within 72 hours postpartum. There was no association between whether or not colostrum could be collected and maternal age or gestational age. There were no adverse events, such as alterations in the respiratory and cardiac frequencies or decrease in oxygen saturation, in the 19 infants who received oropharyngeal colostrum. Regarding the perception of the professional care team about colostrum therapy, more than half reported being partially knowledgeable about the practice and only one felt totally knowledgeable. However, most of the care team (83.4%) reported being satisfied, very satisfied or totally satisfied with the implementation of the colostrum protocol. CONCLUSIONS: In general, this study demonstrated difficulties in the implantation of the protocol of colostrum therapy to premature infants at Hospital Sa?de in Caxias do Sul. The obstacles to the success of a protocol of colostrum therapy were revealed, which mainly resided in the fact that the puerperae had difficulty in exhausting the breast in the first few days after preterm birth, and as a consequence, most newborns were unable to receive maternal colostrum within the first three days of life. In successful cases, the mother's satisfaction with the fact that the child received her colostrum was rewarding. There was a insufficient deepening in the training of the professional care team. These results brought important data that can be used in the execution of a new protocol, in the same unit as well as in other units with the same characteristics. Additional studies should be performed to reveal ways to achieve better success in the application of colostrum therapy protocol, supplanting the difficulties of early breast exhaustion, and can thus benefit from the administration of oropharyngeal colostrum to premature infants.
INTRODU??O: A colostroterapia, tamb?m chamada de terapia imunol?gica oral, ? a administra??o do colostro por via orofar?ngea para rec?m-nascidos prematuros e pode ser iniciada nas primeiras seis horas de vida. S?o administradas pequenas doses de colostro na mucosa oral e trato respirat?rio superior do rec?m-nascido, o que poder? exercer efeito protetor sobre a membrana da mucosa. Al?m disso a imunoglobulina A, as citocinas colostrais, os agentes antioxidantes e todos os agentes anti-infecciosos podem interagir com c?lulas linfoides dentro da orofaringe, estimulando a fun??o imunol?gica do beb?. Recentemente estudos relatam a import?ncia do colostro administrado pela via orofar?ngea, principalmente para o prematuro de extremo baixo peso, com efeitos nutricionais e de defesa imunol?gica j? demonstrados. Quanto mais prematuro o beb?, mais ele se beneficiar? da exposi??o precoce ao colostro. OBJETIVO: Estimar o ?ndice de sucesso ap?s a implanta??o de um protocolo de administra??o de colostro em rec?m-nascidos prematuros de baixo peso, no Hospital Sa?de, em Caxias do Sul/RS. METODOLOGIA: O estudo ocorreu entre mar?o e julho de 2017, ap?s a aprova??o ?tica do projeto. Os participantes foram 41 pares m?e/beb? cujas m?es, ap?s assinatura do consentimento livre e esclarecido, fizeram tentativas de esgotar a mama para prover colostro aos seus filhos. Foram inclu?dos prematuros entre 24 e 32 semanas que tinham indica??o de colostroterapia, prescrita pelo m?dico, sendo iniciadas as tentativas de esgota da mama antes das seis horas de vida do rec?m-nascido. Utilizaram-se dois instrumentos de coleta de dados criados pela pesquisadora, um com informa??es sobre as m?es e sobre os rec?m-nascidos e o outro para a equipe de enfermagem da Unidade de Terapia Intensiva Neonatal responder. Ap?s a observa??o da tentativa de se esgotar ou n?o o colostro, foram contempladas as quest?es do instrumento de coleta, como se a pu?rpera conseguiu esgotar 0,2 mL de leite ou n?o, ou se conseguiu esgotar a mama antes das seis horas. Atrav?s do prontu?rio de cada beb?, foram coletados os dados sobre a administra??o. Observou-se se houve queda de satura??o de oxig?nio e/ou aumento das frequ?ncias respirat?ria e card?aca na hora da administra??o da colostroterapia. Considerou-se como sucesso da colostroterapia a administra??o de pelo menos uma dose de colostro dentro das primeiras 72 horas de vida, sendo o ?ndice de sucesso referido como porcentagem dos casos que obtiveram sucesso entre todos os inclu?dos. RESULTADOS: Entre os 41 prematuros inclu?dos no protocolo, 19 (46,3%) receberam pelo menos uma dose de colostro dentro das primeiras 72 horas de vida e 22 (53,7%) n?o receberam a colostroterapia. Houve associa??o entre conseguir esgotar a mama mais precocemente e o beb? conseguir receber a colostroterapia, independentemente do momento em que a recebeu. Todos os 22 casos de insucesso da colostroterapia se deveram ? n?o obten??o de colostro dentro das 72 horas p?s-parto. N?o houve associa??o entre o fato de conseguir ou n?o coletar o colostro e a idade materna, ou a idade gestacional. N?o houve nenhum evento adverso, como altera??o nas frequ?ncias respirat?ria e card?aca ou diminui??o da satura??o de oxig?nio, nos 19 RN que receberam colostro por via orofar?ngea. Em rela??o ? percep??o da equipe assistencial quanto ? colostroterapia, mais da metade referiu ser conhecedor parcial da pr?tica e apenas um sentia-se totalmente conhecedor. Entretanto, a maior parte da equipe assistencial (83,4%) referiu estar satisfeita, muito satisfeita ou totalmente satisfeita com a implanta??o do protocolo da colostroterapia. CONCLUS?ES: Em geral, este estudo demonstrou dificuldades na implanta??o do protocolo de colostroterapia a prematuros no Hospital Sa?de de Caxias do Sul. Foram revelados os empecilhos para o sucesso de um protocolo de colostroterapia, os quais residiram principalmente no fato de que as pu?rperas tiveram dificuldade em esgotar a mama nos primeiros dias ap?s o parto prematuro e, como consequ?ncia, a maioria dos rec?m-nascidos n?o conseguiu receber o colostro materno dentro dos primeiros tr?s dias de vida. Nos casos de sucesso, a satisfa??o da m?e pelo fato do filho receber o seu colostro foi compensadora. Faltou maior aprofundamento no treinamento da equipe assistencial. Os resultados trouxeram dados importantes que podem ser aproveitados na execu??o de um novo protocolo, na mesma unidade, assim como em outras unidades com as mesmas caracter?sticas. Estudos adicionais devem ser realizados para revelar formas de obter melhor sucesso na aplica??o do protocolo de colostroterapia, suplantando as dificuldades da esgota precoce da mama, podendo assim auferir os benef?cios da administra??o de colostro por via orofar?ngea aos prematuros.

Previous issue date: 2010-12-07OBJETIVO: Primeiramente, avaliar, em uma resina composta, a correla??o existente, em testes de microdureza, entre os fatores carga e tempo de aplica??o, utilizando-se os m?todos de ensaio mec?nico Vickers e Knoop. Em segundo lugar, avaliar, em uma resina composta, os fatores carga e tempo de aplica??o no teste de microdureza Knoop, e mostrar, com os resultados obtidos, quando ? poss?vel, atrav?s dos testes, fazer uma compara??o com o grau de convers?o da resina composta. MATERIAIS E M?TODOS: Resina Grandio (Voco, Cuxhaven, Alemanha), cor A2, foi utilizada para confeccionar as amostras. Noventa (90) amostras foram feitas em uma matriz de politetrafluoretileno com seis (6) mm de di?metro por tr?s (3) mm de profundidade, onde dois incrementos equidistantes foram fotopolimerizados por 20s cada um atrav?s de um dispositivo LED (Celalux, Voco, Cuxhaven, Alemanha, com 800 mW/cm2). As amostras foram divididas aleatoriamente em tr?s grupos de acordo com o fator carga. Os grupos I, II e III receberam cargas de 50g, 100g e 500g, respectivamente. Estes grupos foram divididos em nove subgrupos de acordo com o fator tempo de aplica??o (15s, 30s, 45s). Cada amostra recebeu edenta??es de um dispositivo Shimadzu HMV tester (Shimadzu, Kioto, Jap?o). Os resultados foram analisados estatisticamente atrav?s de ANOVA com fatores fixos (carga e tempo de aplica??o), e ao teste de compara??es m?ltiplas de Tukey (α = 0.05). RESULTADOS: Diferen?as significativas foram encontradas entre os grupos para cada metodologia, Vickers e Knoop (p<0.001). Entre as amostras testadas com a metodologia Vickers (VHN), a m?dia encontrada variou de 164.94 (50g 45s) at? 210.33 (100g 45s). Os valores de microdureza para a metodologia Knoop (KHN) variaram de 128.92 (500g 45s) at? 184.26 (100g 15s). Para ambas as metodologias, tanto o fator tempo e o fator tempo de aplica??o foram estatisticamente significantes (p<0.001), isto mostra que diferentes cargas e tempos de aplica??o influenciam na microdureza das resinas. CONCLUS?O: Primeiramente, este estudo demonstrou que correlacionar os resultados de testes de microdureza Vickers and Knoop n?o ? recomendado, e protocolos similares devem ser aplicados a fim de permitir compara??es entre diferentes estudos que utilizam o mesmo tipo de teste. Em Segundo lugar, este estudo demonstrou que os resultados de microdureza Knoop n?o s?o recomendados para compara??es com o grau de convers?o das resinas compostas, e protocolos similares devem ser aplicados a fim de permitir este tipo de correla??o.

No contexto das doen?as cr?nicas n?o transmiss?veis, que imperam no novo cen?rio epidemiol?gico, faz-se necess?ria a reformula??o do modelo de assist?ncia e a inclus?o de novas tecnologias com o objetivo de formar redes de aten??o ? sa?de capazes de responder de forma satisfat?ria a essa demanda emergente. Diante desse cen?rio, a Gest?o da Cl?nica traz ferramentas importantes, dentre elas as Linhas-Guia (LG) cujas recomenda??es orientam a pr?tica dos profissionais no manejo de condi??es cr?nicas priorit?rias no Sistema ?nico de Sa?de. Contudo, por motivos de ordem pol?tica e organizacional, a implanta??o dessas ferramentas acontece de forma incipiente, sem a efetividade e perenidade esperadas. O objetivo do estudo foi verificar, nos munic?pios da regi?o de sa?de de Itabira, a interfer?ncia na implanta??o das LG dos seguintes processos de trabalho da Aten??o Prim?ria ? Sa?de: territorializa??o, cadastro populacional, diagn?stico situacional, protocolos municipais, agenda, educa??o permanente, plano de cuidado, conselhos locais de sa?de, acesso e coordena??o da Aten??o Prim?ria. Para isso, a partir de um estudo quantitativo transversal, foi utilizada a metodologia multi-attribute utility theory (MAUT). Os resultados apontam para os processos de trabalho agenda, diagn?stico e acesso, os quais apresentaram uma correla??o de moderada a boa, estatisticamente significativa. Verificou-se a frequ?ncia de implanta??o das LG de forma individualizada, evidenciando um n?mero maior de munic?pios utilizando as LG da gestante, hipertens?o e diabetes. Observou-se ainda que, apesar de estarem sob uma mesma jurisdi??o, existem iniquidades na operacionaliza??o dos processos de trabalho entre os munic?pios. Por fim, foi encontrada uma rela??o direta, moderada (0,55) no que tange aos processos de trabalho da Aten??o Prim?ria e implanta??o das LG. Discute-se que os processos de trabalho citados como tendo melhor correla??o configuram estrat?gias fundamentais para fortalecimento de v?nculos e garantia do continuum do cuidado. As LG usadas mais frequentemente auxiliam os profissionais no manejo das condi??es de sa?de mais comuns e, por consequ?ncia, apresentam maior aplicabilidade na rotina assistencial. Buscou-se entender as iniquidades entre os munic?pios a partir das intera??es socioculturais locais.

In the context of chronic non-communicable diseases, in which prevails over the new epidemiological scenario, it is required to reformulate the assistance model and the inclusion of new technologies aiming healthcare networks capable of responding satisfactorily to this emerging demand. Given this scenario, the clinical management introduces important tools, among them, Linhas-Guia (LG/Guidelines), whose recommendations guide the practice of professionals in the management of priority chronicle conditions at SUS (Brazilian Health Service). However, political and organizational bureaucracy results in a lack of effectiveness and expected longevity of the implantation of these tools in an incipient way. The goal of this study was to verify the interference in the implementation of the Guidelines for the following Primary Health Care work processes in the municipalities under the jurisdiction of the Regional Health Management of Itabira: territorialization, population registry, situational diagnosis, municipal protocols, agenda , permanent education, care plan, local health councils, access and coordination of Primary Care. In this regard, it was used a multi-attribute utility theory (MAUT). The results indicate that the work processes agenda, diagnosis, and access presented a correlation of moderate to good, statistically significant. The frequency of LG implantation was verified in an individualized way, emphasizing a larger number of municipalities using pregnant women, hypertension, and diabetes? LG. It was also detected inequities in the operationalization of work processes between municipalities, even though belonging to the same jurisdiction. Finally, a direct connection, moderate relationship (0.55) was found regarding Primary Care working processes and LG implantation. It argues the work processes cited as having the best correlation constitute fundamental strategies to reinforce the bonds and guarantee the continuum of care. The most frequently used LGs help professionals in the management of the most common health conditions and, consequently, have a greater applicability in the care routine. The aim was to understand the inequities between municipalities based on local socio-cultural interactions. The findings widely contribute to the management, within the scope of Health Assessment, at municipal, regional and state level, highlighting the conditions for an effective implementation of LG. Moreover, it strengthens the MAUT methodology as an evaluation tool in the health area.

Cette thèse concerne l'étude de différentes techniques modernes de génie logiciel qui peuvent être mises en ¦uvre pour développer des systèmes de Traitement Automatique des Langues Naturelles de façon générique et extensible. La première partie fait le point sur l'état de l'art en TALN à propos des Langages Spécialisés pour la Programmation Linguistique et permet d'identifier l'intégrabilité, l'extensibilité et la généricité comme trois qualités qu'il est souhaitable de fournir aux systèmes de TALN. La définition d'un modèle à objets (LEAF) et l'affinage d'un modèle d'architecture (tableau blanc) constituent deux premiers éléments de réponse au problème de l'intégration. Une première approche de la généricité et de l'extensibilité est également présentée avec une expérience de réingéniérie du langage LT. La seconde partie approfondit les problèmes de généricité et les illustre avec la définition d'un langage original de représentation linguistique (DECOR). L'introduction de protocoles internes et externes permet de rendre ce langage particulièrement générique et dynamique. La troisième partie fait état de la réingériérie de deux langages spécialisés (ATEF et ROBRA). Cette expérience permet d'introduire une grande extensibilité dans les moteurs de ces langages par une programmation par objets et protocoles. Une question transverse à ces trois parties concerne l'identification des limites et des écueils liés à la recherche de l'intégrabilité, de l'extensibilité et de la généricité. Ces difficultés viennent principalement de la complexité croissante des protocoles adéquats, dont la maîtrise pourrait rapidement échapper au développeur si l'on n'y prend garde.

RFID (Radio Frequency Identification) identifies object by using the radio frequency which is a non-contact automatic identification technique. This technology has shown its powerful practical value and potential in the field of manufacturing, retailing, logistics and hospital automation. Unfortunately, the key problem that impacts the application of RFID system is the security of the information. Recently, researchers have demonstrated solutions to security threats in RFID technology. Among these solutions are several key management protocols. This master dissertations presents a performance evaluation of Neural Cryptography and Diffie-Hellman protocols in RFID systems. For this, we measure the processing time inherent in these protocols. The tests was developed on FPGA (Field-Programmable Gate Array) platform with Nios IIr embedded processor. The research methodology is based on the aggregation of knowledge to development of new RFID systems through a comparative analysis between these two protocols. The main contributions of this work are: performance evaluation of protocols (Diffie-Hellman encryption and Neural) on embedded platform and a survey on RFID security threats. According to the results the Diffie-Hellman key agreement protocol is more suitable for RFID systems

In this day and age, the Internet provides the biggest linkage of information, personal data and information, social contact facilities, entertainment and electronic repository for all things including software downloads and tools, online books and technical descriptions, music and movies - both legal and illegal [Clarke, 1994]. With the increasing bandwidth in the last few years worldwide, it is possible to access the so-called "Triple-Play-Solutions" - Voice over lP, High-Speed-Internet and Video on Demand. More than 100 million subscribers have signed on across Asia, Europe, and the Americas in 2007, and growth is likely to continue steadily in all three. As broadband moves into the mainstream, it is reshaping the telecommunications, cable and Internet access industrie [Beardsley, Scott and Doman, Andrew, and EdinMC Kinsey, Par, 2003]. Cisco [Cisco, 2012], one of the biggest network companies, will expect more than 966 exabytes (nearly 1 zettabyte) per year or 80.5 exabytes per month in 2015 and the "Global IP traffic has increased eightfold over the past 5 years, and will increase fourfold over the next 5 years. Overall, IP traffic will grow at a compound annual growth rate (CAGR) of 32 percent from 2010 to 2015" . More and more types of sensible data flow between different recipients. News from around the world are transferred within seconds from the one end to the other end of the world, and affect the financial market, stock exchange [Reuters, 2012] and also bring down whole governments. For instance, worldwide humoil might ensue if a hacker broke into the web-server of an international newspaper or news channel like N-TV in Germany or BBC in England and displayed messages of a political revolution in Dubai or the death of the CEO from Microsoft or IBM.

Previous issue date: 2009-03-06O Trichomonas vaginalis ? um protozo?rio flagelado causador da tricomonose, a doen?a sexualmente transmiss?vel (DST), n?o-viral mais comum. Ester?ides podem influenciar a patog?nese do Trichomonas vaginalis. Estes horm?nios podem influenciar o sistema imune e tamb?m a suscetibilidade para doen?as causadas por parasitas. Estudos t?m descrito que a modula??o dos n?veis de nucleot?deos pode ser essencial para a sobreviv?ncia do parasito. A coloniza??o por T. Vaginalis pode ser influenciada pela concentra??o de estrog?nios na vagina. O papel dos estrog?nios na patog?nese do T. vaginalis ? controverso, e estudos contradit?rios s?o encontrados na literatura. Considerando que o T. vaginalis n?o realiza s?ntese de novo de purinas e pirimidinas, ? importante avaliar as atividades enzim?ticas envolvidas na produ??o de adenosina na presen?a de horm?nios esteroidais. N?s investigamos o efeito do sulfato de deidroepiandrostenediona (S-DHEA) e do 17b-estradiol nas atividades da NTPDase e da ecto-5?-nucleotidase em um isolado cl?nico fresco (VP60) e em um isolado cultivado por longos per?odos em laborat?rio (30236 ATCC), seguido pela an?lise transcricional dos genes. Os resultados demonstrram a influ?ncia do 17b-estradiol e do S-DHEA nas atividades da NTPDase e da ecto-5?-nucleotidase e padr?es de express?o das NTPDases em trofozo?tos intactos de T. vaginalis. A atividade da NTPDase no isolado 30236 foi inibida no ensaio in vitro e no tratamento na presen?a do horm?nio S-DHEA por 12 h. No isolado VP60, a atividade da NTPDase foi inibida no tratamento com este horm?nio por 2 e 12 h. A presen?a do horm?nio ester?ide S-DHEA por 12 h inibiu a express?o dos n?veis de mRNA da NTPDaseA no isolado VP60. Em contraste, o 17b- estradiol ativou a atividade da NTPDase no isolado VP60 no ensaio in vitro e no tratamento por 12 h. A atividade da NTPDase no isolado 30236 foi ativada na presen?a do 17b- estradiol quando tratado por 12 h. Por outro lado, o tratamento com o horm?nio 17b- estradiol por 2 h inibiu a atividade da NTPDase no isolado 30236. O tratamento na presen?a do S-DHEA por 2 h inibiu a hidr?lise do AMP no isolado VP60 e no isolado 30236. O 17b-estradiol, no tratamento de 2 h, diminuiu a hidr?lise do AMP no isolado 30236, mas n?o alterou a hidr?lise do AMP no isolado VP60. O tratamento por 12 h na presen?a do horm?nio S-DHEA inibiu a hidr?lise do AMP. Considerando que a vagina ? um ambiente constantemente afetado pelas mudan?as hormonais e que os efeitos dos horm?nios esteroidais s?o influenciados por receptores presentes no T. vaginalis, nossos resultados sugerem que a modula??o dos n?veis extracelulares de ATP, ADP e AMP durante a exposi??o aos horm?nios esteroidais pode estar relacionada com a coloniza??o do T. vaginalis.

Pesquisas relacionadas com sistemas utilizando diversos ve?culos a?reos n?o tripulados (multi VANTs) v?m crescendo nos ?ltimos anos. Entre os desafios enfrentados, uma rede de comunica??o de dados robusta ? crucial para coopera??o e colabora??o entre VANTs. No projeto da rede devem ser levados em conta fatores como o prop?sito da miss?o da esquadrilha, planejamento de caminho e trajet?ria, coleta de dados dos sensores e suprimento energ?tico. Dessa forma, o presente trabalho apresenta a especifica??o de uma arquitetura de rede de comunica??o de dados para uma esquadrilha de Ve?culos A?reos N?o Tripulados a serem utilizados na varredura da ?rea de impacto de foguetes lan?ados a partir do Centro de Lan?amento da Barreira do Inferno (CLBI ? Rio Grande do Norte). Assim, realiza-se um estudo sobre as principais caracter?sticas das redes de comunica??o para sistemas multi VANT e as especificidades da aplica??o abordada nesse projeto. S?o propostas duas estrat?gias diferentes para a varredura da ?rea de impacto de foguetes. S?o analisadas as caracter?sticas das redes para sistemas multi VANTs mais adequadas a essas estrat?gias, de forma a fazer uma an?lise comparativa entre as mesmas e definir uma arquitetura apropriada para a aplica??o. Dentro desse contexto, ? proposta uma arquitetura de rede, com base em m?dulos XBee Pro 900HP, integrados em uma plataforma de hardware controlada por computador embarcado, equipado com GPS e placa controladora de piloto autom?tico. ? idealizado e implementado um plano de testes com os dispositivos XBee para avaliar o desempenho destes na arquitetura de rede proposta em termos de robustez, confiabilidade e economia de energia. Para aferi??o do desempenho nos poss?veis cen?rios de forma??o da esquadrilha de VANTs s?o utilizados softwares de ger?ncia de rede, visando medir a largura de banda (throughput), perda de pacotes e outros indicadores de desempenho nos links de comunica??o entre os diferentes n?s da rede.
Research on Multi Unmanned Aerial Vehicle Systems (Multi-UAV) is growing in recent years. Among several scientific and technical challenges, a robust data communication network is crucial for the cooperation and collaboration between the UAVs. The network design must take into account factors such as the purpose of the mission, trajectory and path planning, sensor data collection and energy supply. In this way, the present work presents the specification of a data communication network architecture for a squadron of Unmanned Aerial Vehicles to be used in the scanning of the rocket impact area for CLBI rocket launch center (Rio grande do Norte, Brazil). Thus, a study on the main characteristics of communication networks for multi-UAV systems and the specificities of the application addressed in this project is done. Two different strategies for the scanning of the rocket impact area are proposed. In order to do a comparative analysis between these strategies and to define an appropriate architecture for the application, the characteristics of the networks for multi-UAV systems that are more appropriate to them are analyzed. In this context, a network architecture based on Xbee Pro 900HP S3B modules, integrated in an embedded computer hardware platform, equipped with GPS and autopilot controller board is proposed. A test plan with Xbee devices is conceived and implemented in order to evaluate their performance in the proposed network architecture in terms of robustness, reliability and energy consumption. In order to measure performance in the possible UAV squad formation scenarios, a network management software is used to measure throughput, packet loss and other performance indicators in the communication links between the different nodes of the network.

OBJETIVO: Este estudo tem como objetivo elaborar um protocolo eficiente para triagem do desenvolvimento de linguagem em crianças da população brasileira, analisar se existem diferenças nas habilidades de linguagem das crianças com e sem fissura labiopalatina (FLP) e verificar se há diferenças no perfil do desenvolvimento de linguagem entre crianças com FLP, com e sem otite média. MODELO: Prospectivo e amostra aleatória. LOCAL: Setor de Fonoaudiologia e Ambulatório de Saúde Pública - HRAC- USP. PARTICIPANTES: Foram avaliadas 163 crianças, sendo 102 com FLP (50 sem e 52 com otite média) e 61 sem FLP, na faixa etária de 22 a 24 meses e de 34 a 36 meses, por ordem de agendamento no HRAC - USP. INTERVENÇÕES: Aplicação do Protocolo de triagem do desenvolvimento de linguagem em crianças até 3 anos de idade, composto dos Testes REEL-2, ELM e LDS e avaliação fonoaudiológica, possibilitando a detecção precoce de crianças de risco para o atraso no desenvolvimento da linguagem. RESULTADOS: Constatou-se, com diferença estatisticamente significante, atraso no desenvolvimento da linguagem receptiva pelo Teste REEL-2, em crianças com 3 anos de idade, sendo mais baixo o desempenho naquelas com FLP. A Escala ELM mostrou diferença estatisticamente significante para a linguagem expressiva com 3 anos de idade, destacando-se o grupo de crianças sem FLP. No Teste LDS os dados foram significativos para crianças com 3 anos, do grupo sem FLP. Todos esses dados foram confirmados pela avaliação fonoaudiológica. CONCLUSÃO: O protocolo proposto mostrou eficácia, principalmente quando acentua as diferenças existentes em crianças com e sem FLP. Com esses dados, a implantação do protocolo é de alto benefício aos pacientes de risco nesta condição.Objective: The goals of the present work are: to generale a protocol screening to evaluate the development of language in Brazilian children; to analise differences existing in language skills in children with/without cleft lip/palate, and to verify differences existing in the profile of language development between children with clefting, with/ without median otitis. Model: Prospective study based in randomized sampling Setting: Speech Pathology Section, Public Health Ambulatory, HRAC-USP Participants: 163 children composed this sample, where 102 presented cleft lip/palate (52 with otitis media and 50 without) and 61 normal children. The age ranged between 22 to 24 months and from 34 to 36 months, according the routine agenda. Intervention: The Protocol was applied to all children having less than 36 months. It includes the following scales: REEL-2, ELM and LDS, as well as the speech language evaluation, concerning early identification of children at risk for developmental language delay. Results: Through the Protocol screening we showed that there was significant standard deviation in receptive developmental language delay detected through the REEL-2 Scale, mainly for children with CL/P at age 36 months. The ELM and LDS scales showed significant standard deviation for expressive language delay, mainly in children without clefting at age 36 months. These data were confirmed through speech-language evaluation. Conclusions: The studied Protocol was efficient in all circumstances, mainly when we take into account the differences existing between children with cleft lip/palate with and without otitis media, and when we also consider the groups with and without CL/P. We suggest that this Protocol should be established as a routine procedure in the evaluation of at risk patients, no matter where they are.

Introdução e Objetivo: Nos pacientes com fissura labiopalatina unilateral (FLPU) as cirurgias primárias afetam, em graus variados, o crescimento da face, comprometendo a estética facial e a oclusão dentária. Diversos estudos enfatizam a necessidade de se estabelecer protocolos cirúrgicos que apresentem repercussões positivas no crescimento facial e no desempenho fonoarticulatório dos pacientes, visando a diminuição do custo biológico, social e financeiro do tratamento integral. Este estudo objetivou comparar os efeitos de dois protocolos cirúrgicos para palatoplastia primária, em um e em dois tempos cirúrgicos, este com o fechamento tardio do palato duro (FTPD) sobre o complexo maxilo-mandibular de pacientes com FLPU completa. A hipótese do autor é que o protocolo com FTPD propicie um melhor crescimento dentofacial. Métodos: Foi realizado um ensaio clínico randomizado no qual 64 pacientes, atendidos em um centro de referência no nordeste do Brasil, foram divididos em dois grupos que receberam tratamentos cirúrgicos distintos. O grupo de intervenção (GI) foi constituído por 32 pacientes submetidas à palatoplastia em dois tempos cirúrgicos: veloplastia realizada entre os 6 e 9 meses de idade e FTPD realizado entre 36 e 48 meses de vida. O grupo controle (GC) foi constituído por 30 pacientes submetidos a palatoplastia completa entre os 9 e 15 meses. A relação entre os arcos dentários foi avaliada, de maneira cega, por três ortodontistas calibrados usando o índice FYOI (Atack,1997). Também foram investigadas as alterações dimensionais na maxila, a gravidade da fissura e as complicações pós-cirúrgicas em relação aos dois protocolos cirúrgicos. Resultados: Os modelos de gesso para avaliação pelo FYOI foram obtidos dos pacientes de ambos os grupos com idade média de 55,5 meses. O grau de concordância foi excelente (Kappa = 0,76-0,90) entre os examinadores e bom intra-examinadores (Kappa = 0,67-0,87). Os escores médios do índice FYOI variaram de 2,04 no GI a 2,76 no GC, com diferença estatisticamente significante (p = 0,007). Quando os scores foram agrupados em três categorias, bom (escores 1 e 2), Regular (escore 3) e ruim (escores 4 e 5) verificou-se diferença significativa (p < 0,006) na categoria bom (escores 1 e 2) entre os grupos GI (74%) e GC (52%). Ao serem comparadas as distribuições pela mediana, foi encontrada diferença significativa (p = 0,024) entre os escores 1 dos grupos GI (31,2%) e GC (3,3%). A correlação entre a largura da fissura e a relação maxilo-mandibular avaliada pelo FYOI não foi evidenciada pelo método de Spearman. A ocorrência de fístulas oronasais foi de 9,4% no GI e 6,7% no GC, sem diferença significativa entre eles. Conclusões: a palatoplastia realizada em dois tempos cirúrgicos com FTPD, apresenta melhores desfechos relativos ao crescimento dentofacial em crianças com FLPU. Não foi encontrada associação entre a gravidade da fissura e os desfechos relacionados ao crescimento maxilar. Não há diferenças estatisticamente significantes entre os dois protocolos cirúrgicos em relação à ocorrência de fístulas e à diminuição da distância intercaninos e diminuição do comprimento do arco maxilarBackground and Objective: An adequate growth of dentofacial structures is one of the most important goals of unilateral cleft lip and palate(UCLP) treatment and has a definitive role in getting good aesthetic and dental occlusion outcomes. To the present date several papers highlight the need of evidence-based studies to find surgical protocols that can improve facial growth and speech results aiming to reduce the burden of care of overall treatment. This study has evaluated and compared the dental arch relationship at 5 years of age after two treatment protocols, one submitted to one stage cleft palate repair (CPR) and the other to a two stage CPR with delayed hard palate closure (DHPC). The author\'s hypothesis is that the DCHP protocol provides a better dentofacial growth. Methods: A randomized clinical trial was held to evaluate the maxilo-mandibular relations in two groups of initially 32 patients each, randomly chosen. The GI group (n=32) was submitted to veloplasty between 6-9 months of age and a DCHP palatoplasty between three and four years of of age. The immediate complications were evaluated, oronasal fistulas, and cleft severity and their relationships to the surgical protocols. The dental arch relationships were assessed by a blind panel of three independent orthodontists using the FYOI index. The Kappa statistics were calculated to ensure the level of confidence. The results were statistically tested by t and Q-squared tests. Results: The GI group consisted of 32 patients while the GC group consisted of 30 patients. The oronasal fistulas incidence rate was 9.4% (GI) and 6.7% (GC), and there was no association to surgical techniques. Study models of 62 patients at the average age of 55.5 months were available for assessment. Good to very good levels of intra- and interrater reliability were obtained (0.67-0.87 and 0.76-0.90). The mean index scores varied between 2.04 (GI) and 2.76 (GC) with a statistically significant difference (p=0.007). When all evaluations were distributed between indexes good (1 and 2), regular (3) and bad (4 and 5); a statistically significant difference was observed between the GI and GC groups (p = 0.006),. The GI Group presented a 74% rate of good scores, while the GC Group rated 52% in good scores. When comparing the distributions by median, a difference (p = 0.024) was found between scores 1 of the GI (31.2%) and GC (3.3%) groups. The correlation between the cleft severity and the dental arch relationships assessed by the FYOI was not evidenced by the Spearman method. Conclusions: The ECR results provide statistical evidence that the DCHP protocol delivers better outcomes related to dentofacial growth. There was no correlation found between the cleft severity, palatal width and the results related to maxilar growth. The prevalence of oronasal fistules is similar in both surgical protocols

A fissura labiopalatina e a agenesia dentária são consideradas alterações do desenvolvimento embrionário. Esses fenótipos ocorrem em decorrência da interação de fatores genéticos e ambientais, caracterizando um padrão de herança multifatorial. Entre os genes candidatos a esses fenótipos destaca-se o IRF6. Para esses estudos genéticos podem ser usadas diferentes metodologias, dentre elas o seqüenciamento direto. A proposta deste estudo foi primeiramente padronizar um protocolo para seqüenciamento direto de DNA genômico a partir de saliva e então investigar mutações ou polimorfismos no éxon 3 do gene IRF6 em indivíduos com fissura de lábio e palato unilateral não-sindrômica e agenesia dentária. Fizeram parte do estudo 120 voluntários distribuídos em quatro grupos: Grupo 1 30 indivíduos com fissura e agenesia dentária; Grupo 2 - 30 indivíduos somente com fissura; Grupo 3 - 30 indivíduos somente com agenesia dentária e Grupo 4 - Controle. Para análise do éxon 3 do gene IRF6 foi coletada saliva, e a partir desse material foram testados três protocolos para extração de DNA genômico. Além disso, durante a padronização do protocolo para seqüenciamento direto foram avaliadas metodologias diferentes para outras três etapas da preparação das amostras: purificação do produto de PCR, otimização na utilização do BigDye® v3.1 Terminator na reação de seqüenciamento e purificação do produto da reação de seqüenciamento. As amostras foram seqüenciadas em Analisador Genético ABI 3130XL e os resultados analisados por meio de programas de computador específicos. Foram pesquisadas, nos eletroferogramas referentes ao éxon 3 do gene IRF6, variações nas seqüências de cada indivíduo. Os resultados mostraram que o protocolo de extração de DNA a partir de saliva utilizando InstaGeneTM Matrix associado à proteinase K e dodecil sulfato de sódio 1% foi o que apresentou melhores resultados na quantidade e qualidade do DNA extraído. Em relação à purificação do produto de PCR, o método de escolha foi a purificação em coluna específica. O BigDye® v3.1 foi utilizado com sucesso em um volume de 2 L por reação, e a purificação do produto de seqüenciamento com XTerminator apresentou os melhores resultados. Na triagem de mutação, somente um indivíduo do grupo controle apresentou variação na seqüência do tipo heterozigoto. Concluiu-se que é possível realizar, com sucesso, na plataforma ABI 3130XL, o seqüenciamento direto de DNA genômico extraído a partir de saliva total utilizando os protocolos padronizados neste trabalho. Concluiu-se também, que neste grupo analisado, não houve associação entre o éxon 3 do gene IRF6 e os fenótipos fissura labiopalatina não-sindrômica e agenesia dentária.Cleft lip and palate and tooth agenesis are considered changes in embryonic development. These phenotypes occur as a result of the interaction of genetic and environmental factors, suggesting a multifactorial inheritance pattern. Among the candidate genes for these phenotypes IRF6 appears as one of the most important. Direct sequencing, among other techniques, can be used to perform such genetic studies. The aim of this study was to standardize a protocol for direct sequencing of genomic DNA extracted from whole saliva to allow further search of mutations or polymorphisms in exon 3 of IRF6 gene in individuals with nonsyndromic cleft lip and palate and tooth agenesis. Volunteers were 120 subjects divided into four groups: Group 1 - 30 individuals with tooth agenesis and cleft, Group 2 - 30 individuals with cleft only, Group 3 - 30 individuals with tooth agenesis only, and Group 4 - Control. For the analysis of the exon 3 of IRF6 gene, saliva was collected to test three protocols for the extraction of genomic DNA. Additionally, during the protocol standardization for direct sequencing, different methodologies for the other three steps of sample preparation were evaluated: purification of PCR product, optimization of the use of BigDye® v3.1 Terminator, and purification of the sequencing product. The samples were sequenced on ABI 3130XL Genetic Analyzer, and the results were analyzed using specific softwares. Heterozygous and homozygous variations in the sequences of the exon 3 of IRF6 gene of each individual were searched in the electropherograms. The results showed that the protocol for DNA extraction from saliva using InstageneTM Matrix associated with proteinase K and 1% sodium dodecyl sulfate showed the best results in the quantity and quality of the extracted DNA. As far as the purification of the PCR product, the method of choice was the purification in specific columns. BigDye® v3.1 was used with success in a volume 2 L per reaction, and the purification of the sequencing product with X-Terminator showed the best results. For the mutation screening, only one individual of the control group presented sequence variation of the heterozygous type. It was concluded that it is possible to successfully perform, on the ABI 3130XL platform, the direct sequencing of genomic DNA extracted from whole saliva using the protocols standardized in this work. It was also concluded that in the group analyzed, no association between the exon 3 of IRF6 gene and the phenotypes of nonsyndromic cleft lip and palate and tooth agenesis was found.

Nous présentons dans cette thèse de nouveaux protocoles de routage capables de prendre en compte des aspects stratégiques lorsqu’il s’agit de choisir le chemin à emprunter et ce à l’échelle du réseau de communication Internet. Le point de vue adopté dans cette étude est que les nouvelles architectures de routage donnent aux réseaux et aux applications une plus grande diversité de chemins, ce qui leur permet de choisir plus rationnellement leur stratégie lorsqu'ils décident le chemin à suivre pour transférer leur trafic, en tenant compte des coûts opérationnels ainsi que des objectifs de performance. Nous présentons des comportements améliorés au noyau décisionnel de trois protocoles de routage, le protocole BGP (Border Gateway Protocol), le protocole LISP (Locator / Identifier Separation Protocol) et, dans une moindre mesure, le protocole MPTCP (Multipath TCP). Pour chaque cadre protocolaire, nous présentons comment les stratégies de routage peuvent être déterminées, sélectionnées et réellement exploitées par des systèmes réels, en appliquant également les concepts de la théorie des jeux non coopératifs, en évaluant l’impact des solutions de routage en termes de coûts opérationnels et de performances réseau. La thèse adopte une méthodologie expérimentale permettant de tester et d'évaluer les propositions via des simulations réalistes et la mise en œuvre et l'observation réelles de systèmes réels. La plupart des résultats sont reproductibles grâce à la publication du code sourceWe present in this thesis novel routing protocols able to take into consideration strategic aspects when deciding which path among many to take, and that at the Internet communication network scale. The standpoint adopted in this study is that novel routing architectures are exposing a higher path diversity to networks and applications so that networks and applications can be made capable to more intelligently select their strategy when selecting toward which path to forward their traffic, taking into consideration operational costs as well as performance goals. We present enhanced behaviors to the decision-making core of three routing protocols, the Border Gateway Protocol (BGP), the Locator/Identifier Separation Protocol (LISP) and, at a minor extent, the Multipath TCP (MPTCP) protocol. For each protocol framework we present how routing strategies can be computed, selected and actually operated by real systems, also applying concepts from non-cooperative game theory, evaluating the impact of the routing solutions in terms of operational costs and network performance. The thesis adopts an experimental methodology willing to experiment and evaluate proposals via realistic simulations or actual implementation and observation of real systems. Most of the results are made reproducible by open sourcing the corresponding code

O objetivo desta disserta??o ? discutir o processo de autonomiza??o da assinatura ?Gustavo Barroso? por meio do exame do discurso narrativo presente em Ideias e Palavras, em A Ronda dos S?culos e em Os Protocolos dos S?bios de Si?o, obras publicadas por Gustavo Adolfo Dodt Luiz Guilherme da Cunha Barroso entre 1917 e 1936. Defendemos a ideia de que Os Protocolos dos S?bios de Si?o constituem um novo texto produzido por Barroso a partir dos insumos das suas obras anteriores, e n?o simplesmente uma tradu??o da vers?o francesa do documento-marco do antissemitismo contempor?neo. Nesse intuito, baseamo-nos nos textos da Nova Hist?ria Pol?tica, da hist?ria do espa?o nacional e da Religi?o Pol?tica para percebermos como essa assinatura vai se adensando a partir da tese do imperialismo judaico e da afirma??o da nacionalidade brasileira, tendo em vista a produ??o de um discurso narrativo contra os judeus. Em respeito a isso, utilizamos como referencial metodol?gico os livros Narrative Discourse: An Essay in Method (1990) e Paratexts: Thresholds of interpretation (2001), de G?rard Genette, e dedicamos um cap?tulo da disserta??o para cada obra. No primeiro cap?tulo, caracterizamos o discurso narrativo de Ideias e Palavras, mostrando como a dubiedade da assinatura ?Jo?o do Norte (Gustavo Barroso)? explicita uma aprecia??o positiva dos judeus. No segundo cap?tulo, caracterizamos o discurso narrativo de A Ronda dos S?culos pensando a autonomia da assinatura e o processo de negativa??o dos judeus. No terceiro cap?tulo, analisamos o discurso narrativo dos Protocolos dos S?bios de Si?o e discutimos que a assinatura ?Gustavo Barroso?, j? aut?noma, assume a forma de antijuda?smo e antissemitismo. Demonstramos a continuidade da escala internacional como compreens?o espacial e temporal, a descri??o de ambientes f?sicos como pressuposto da psicologia dos personagens, a inser??o de p?ssaros como marca??o das clivagens na narrativa, o aparecimento da guerra como constante hist?rica, cita??o de judeus para discorrer sobre os judeus e a compreens?o da natureza humana como tendente ? destrui??o. Estudar os escritos de Gustavo Barroso ? importante na medida em que ele ? considerado o expoente do antissemitismo brasileiro, foi ele quem concatenou teoricamente o confluxo entre catolicismo e integralismo, de modo que ele se tornou um dos autores mais citados pelos antissemitas contempor?neos como uma forma legitimar as persegui??es ?s minorias e o pensamento autorit?rio.
This study aims discuss the process of autonomy of signature ?Gustavo Barroso? with the exam of the Narrative discourse present in Ideias e Palavras, A Ronda dos S?culos and Os Protocolos dos S?bios de Si?o, books published by intellectual Brazilian Gustavo Adolfo Dodt Luiz Guilherme da Cunha Barroso between 1917 and 1936. We defend the idea that Os Protocolos dos S?bios de Si?o [The Protocols of the Elders of Zion] constitute a new text, not simply a translation of French version. . In this sense, we are based on the texts of the New Political History, the history of the national space and the Political Religion, in order to understand how this signature builds on the thesis of the Jewish imperialism and the affirmation of Brazilian nationality, in view of the production of narrative discourse against the Jews. In this respect, we use as a methodological reference the books Narrative Discourse: An Essay in Method (1990) and Paratexts: Thresholds of interpretation (2001), by G?rard Genette, and dedicate a chapter of the dissertation for each work. In the first chapter, we characterize the narrative discourse of Ideias e Palavras, showing how the dubiousness of the signature "Jo?o do Norte (Gustavo Barroso)" makes explicit a positive appreciation of the Jews. In the second chapter, we characterized the narrative discourse of A Ronda dos S?culos, thinking about the autonomy of the signature and the process of negativation of the Jews. In the third chapter, we analyze the narrative discourse of Os Protocolos dos S?bios de Si?o and we discuss that signature "Gustavo Barroso" and Anti-semitism. We demonstrate the continuity of the international scale as spatial and temporal comprehension, the description of physical environments as a presupposition of the psychology of the characters, the insertion of birds as a mark of the cleavages in the narrative, the appearance of war as a historical constant, citation of Jews to discuss the Jews and the understanding of human nature as tending to destruction. Studying the writings of Gustavo Barroso is important insofar as he is considered the exponent of Brazilian anti-Semitism, it was he who theoretically concatenated the conflux between Catholicism and integralism, so that he became one of the authors most quoted by contemporary anti-Semites as a form legitimize persecution of minorities and authoritarian thinking.

Les systèmes à base de connaissances sont devenus très complexes à cause de leur volume et de leur diversité, et leur maintenance est difficile. L'approche multi-agent offre actuellement un certain nombre de possibilités pour améliorer la structuration, la modularité et l'évolution de ces systèmes. Toutefois, le développement effectif d'un SMA présente un grand nombre de difficultés. En effet, on souffre de l'absence de modèle d'agent générique, d'un certain flottement concernant les niveaux des protocoles (confusion des niveaux et absence de normes). De plus, la distribution effective sur des machines distinctes est difficile, les problèmes liés à l'asynchronisme (programmation événementielle), et les problèmes de reconfiguration dynamique ajoutent à la complexité de réalisation de tels systèmes. Dans ce travail nous montrons qu'il est possible de réaliser un environnement de développement de systèmes d'agents permettant de réduire ces difficultés. De plus, un tel environnement peut être organisé de façon à être utilisé à la fois par des non spécialistes, mais aussi par des experts. Pour l'utilisateur non spécialiste, nous proposons un langage simple de création d'agents (conservant la puissance des langages sous-jacents), une gestion automatique des protocoles, une gestion automatique de l'asynchronisme, et un modèle d'agent générique à partir duquel les agents réels peuvent être clonés. Le spécialiste, lui, pourra exercer un meilleur contrôle, par exemple pour changer le comportement d'un agent en redéfinissant certains mécanismes de base. Notre proposition s'appuie sur le concept d'objets et nous nous plaçons dans le cadre de la programmation orientée-objets (langage OSS) avec comme langage sous-jacent Common Lisp. Dans cet environnement nous réutilisons plusieurs approches comme : le modèle OMG CORBA, permettant d'utiliser des langages hétérogènes, notamment autres que Lisp ; le modèle de Contract-Net, que nous avons modifié pour en tirer un protocole de distribution des tâches qui, par son principe de fonctionnement, améliore la prise de décision du côté du manager en réalisant une allocation de taches progressive et utilisant plusieurs niveaux de priorité. Enfin, pour faciliter le développement des agents d'un système, nous proposons aussi des outils de mise au point, qui permettent, d'une part de tracer les échanges à l'aide d'un agent particulier qui examine tous les messages qui passent sur le réseau et construit une représentation virtuelle du système à l'aide d'icônes et de texte, d'autre part de tester le comportement d'un agent en cours de définition en mode simulé, sous le contrôle strict du concepteur avant de l'installer après validation, après quoi il devient réellement autonome. La plate-forme développé, OSACA, a été testée et est actuellement utilisée dans plusieurs autres projets : MEMOLAB, DIDE.

Metodologia: Foram utilizados 60 pr?-molares humanos, os quais foram contaminados com uma cultura pura de E. faecalis com uma vari?vel de 3.9 a 6.3 x 107(CFU/ml) por um per?odo de 60 dias para forma??o do biofilme bacteriano. Os dentes foram divididos aleatoriamente em 8 grupos sendo que os grupos que fizeram uso de ultrassom tiveram um n= 10 e os grupos grupos controle (sem ultrassom) um n=5. Grupo 1- irriga??o ultrass?nica com hipoclorito de s?dio 2,5%; grupo 2- irriga??o ultrass?nica com clorexidina l?quida 2%; grupo 3- irriga??o ultrass?nica com clorexidina gel 2%; grupo 4- irriga??o ultrass?nica com ?gua destilada; grupo 5- irriga??o convencional com hipoclorito de s?dio 2,5%; grupo 6- irriga??o convencional com clorexidina l?quida 2%; grupo 7- irriga??o convencional com clorexidina gel 2% e grupo 8- irriga??o convencional com ?gua destilada. Foi realizada an?lise em Microsc?pio Eletr?nico de Varredura (MEV). Resultados: Na an?lise em MEV em um aumento de 2000x em backscattering, analisou-se a remo??o da smear layer e houve diferen?a significativa entre os grupos em todos os ter?os. Os grupos 1 e 2 apresentaram uma melhor capacidade de limpeza e foram similares em seus resultados. O grupo que apresentou um pior desempenho foi o grupo 7. No aumento de 10000X em backscattering, analisou- se a presen?a de bact?ria no canal radicular e novamente houve diferen?a estat?stica entre os grupos em todos os ter?os. Os grupos que apresentaram menor biofilme bacteriano foram os grupos 1 e 2 e foram similares em seus resultados. O grupo que apresentou um pior desempenho no ter?o apical foi o grupo 8 e nos ter?os m?dio e cervical o grupo 7. Conclus?es: Independente da solu??o, irriga??o ultrass?nica mostrou-se superior ? irriga??o convencional, indicando que o ultrassom deve ser utilizado como um excelente auxiliar na limpeza e desinfec??o do canal radicular

Consumers of digital contents are empowered with numerous technologies allowing them to produce perfect copies of these contents and distribute them around the world with little or no cost. To prevent illegal copying and distribution, a technology called Digital Rights Management (DRM) is developed. With this technology, consumers are allowed to access digital contents only if they have purchased the corresponding licenses from license issuers. The problem, however, is that those consumers are not allowed to resell their own licenses- a restriction that goes against the first-sale doctrine. Enabling a consumer to buy a digital license directly from another consumer and allowing the two consumers to fairly exchange the license for a payment are still an open issue in DRM research area. This thesis investigates existing security solutions for achieving digital license reselling and analyses their strengths and weaknesses. The thesis then proposes a novel Reselling Deal Signing (RDS) protocol to achieve fairness in a license reselling. The idea of the protocol is to integrate the features of the concurrent signature scheme with functionalities of a License Issuer (LI). The security properties of this protocol is informally analysed and then formally verified using ATL logic and the model checker MOCHA. To assess its performance, a prototype of the RDS protocol has been developed and a comparison with related protocols has been conducted. The thesis also introduces two novel digital tokens a Reselling Permission (RP) token and a Multiple Reselling Permission (MRP) token. The RP and MRP tokens are used to show whether a given license is single and multiple resalable, respectively. Moreover, the thesis proposes two novel methods supporting fair and secure digital license reselling. The first method is the Reselling Deal (RD) method which allows a license to be resold once. This method makes use of the existing distribution infrastructure, RP, License Revocation List (LRL), and three protocols: RDS protocol RD Activation (RDA) protocol, and RD Completion (RDC) protocol. The second method is a Multiple License Reselling (MLR) method enabling one license to be resold N times by N consumers. The thesis presents two variants of the MLR method: RRP-MR (Repeated RP-based Multi-Reselling) and HC-MR (Hash Chain-based Multi-Reselling). The RRP-MR method is designed such that a buyer can choose to either continue or stop a multi-reselling of a license. Like the RD method, the RRP-MR method makes use of RP, LI, LRL, and the RDS, RDA, and RDC protocols to achieve fair and secure reselling. The HC-MR method allows multiple resellings while keeping the overhead on LI at a minimum level and enable a buyer to check how many times a license can be further resold. To do so, the HC-MR utilises MRP and the hash chain cryptographic primitive along with LRL, LI and the RDS, RDA and RDC protocols. The analysis and the evaluation of these three methods have been conducted. While supporting the license reselling, the two methods are designed to prevent a reseller from (1) continuing using a resold license, (2) reselling a non-resalable license, and (3) reselling one license a unauthorised number of times. In addition, they enable content owners of resold contents to trace a buyer who has violated any of the usage rights of a license bought from a reseller. Moreover, the methods enable a buyer to verify whether a license he is about to buy is legitimate for re-sale. Furthermore, the two methods support market power where a reseller can maximise his profit and a buyer can minimise his cost in a reselling process. In comparison with related works, our solution does not make use of any trusted hardware device, thus it is more cost-effective, while satisfying the interests of both resellers and buyers, and protecting the content owner's rights.

The Arizona Child Acoustic Database consists of longitudinal audio recordings from a group of children over a critical period of growth and development (ages 2-7 years). The goal of this database is to 1) document acoustic changes in speech production that may be related to physical growth 2) inform development of a model of speech production for child talkers. This work was funded by NSF BSC-1145011 awarded to Kate Bunton, Ph.D. and Brad Story, Ph.D, Principal Investigators.
This database contains longitudinal audio recordings of 55 American English speaking children between the ages of 2-7 at 3-month intervals. Since children began the study at different ages, some children have fewer recording sessions than others. The database can also be used to provide cross-sectional data for children of a specific age. Please refer to the subject data table for information on specific sessions available here http://arizona.openrepository.com/arizona/handle/10150/316065.
All children were recorded using the same protocol; therefore, task numbers are consistent across children and sessions. A calibration tone is included as Record 1 for all sessions. The speech protocol focused on production of English monopthong and diphthong vowels in isolation, sVd, hVd, and monosyllabic real words. In addition, the protocol includes several nonsense vowel-to-vowel transitions. Speakers were prompted either verbally by investigators or by graphical prompts. Details of the protocol with reference to task numbers can be found in the protocol spreadsheet available here http://arizona.openrepository.com/arizona/handle/10150/316065.
Details on data recording:
All samples were recorded digitally using an AKG SE 300B microphone with a mouth to mic distance of approximately 10 inches. Signals were recorded digitally using a Marantz PMD671, 16 bit PCM (uncompressed) at 44.1KHz. Recordings are made available in .wav format. Individual zip files contain all recordings from a single session.

The Internet Engineering Task Force designed a next-generation routing architecture, called the Locator Identifier Separation Protocol (LISP), to solve the problem of excessively numerous routing tables and insufficient border gateway protocol routing scalability. LISP implements Routing Locators (RLOC) and Endpoint Identifiers (EIDs) for IP addressing to yield the ability to move EIDs without breaking data connections. The Access Control List (ACL) is one of the most popular applications, which is used to restrict, classify, and identify traffic protocols, e.g. TCP, UDP, and ICMP, from source or destination. However, the ACL’s protection becomes inefficient when EIDs move to new xTR because ACL rules are irremovable. We proposed a novel ACL mobility mechanism to implement ACL rules into LISP architecture to defend against attacks. Specifically, in our proposed method, ACL rules were integrated into Map Register and Map Notify to transmit from xTR to Map Server and Map Server to xTR when an EID moves from xTR to another xTR (new), respectively. Thus, ACL rules can be moveable based on EIDs locations.

Currently a need exists in South Africa for an age-, linguistically- and culturally appropriate perceptual speech assessment protocol for Zulu-speaking pre-school children with cleft palate. The aim of this study was to develop a reliable perceptual speech assessment protocol for Zulu-speaking pre-school children with cleft palate based on the international guidelines (www.eurocran.org). Furthermore the clinical applicability and relevance of these guidelines for the perceptual assessment of cleft palate speech in the Zulu language were determined. The aims were reached by following a mixed methods research approach and by conducting the research in four phases. In phase one the protocol was compiled with the assistance of an expert Zulu linguist, in phase two the protocol was pre-tested on 12 normal Zulu-speaking pre-school children between three and six years of age; in phase three the perceptions of speech-language therapists regarding the clinical applicability of the protocol were determined after administration thereof on 12 Zulu-speaking pre-school children with cleft palate between the ages of three and six years; and finally in phase four the relevance of applying the international guidelines to the Zulu language was reflected on. A critical analysis of the protocol indicated that the international guidelines (www.eurocran.org) could be used to develop a perceptual speech assessment protocol in an African language namely Zulu. Results of the pilot study revealed that the protocol was age, culturally and linguistically appropriate for normal Zulu-speaking pre-school children. The speech-language therapist participants indicated that the protocol was clinically applicable to Zulu-speaking pre-school children with cleft lip and palate in terms of cultural sensitivity, administration time and its ability to elicit and identify cleft palate speech characteristics. The international guidelines (www.eurocran.org) could be applied to the Zulu language with an emphasis on the click sounds in Zulu. The results have clinical implications for cleft palate service delivery in South Africa. These implications were for in-service training of speech-language therapists regarding cleft palate to provide them with evidence-based guidelines for clinical practice. Implications for further research included the development of norms of speech development in the Zulu language and the standardization of the perceptual speech assessment protocol. This study is valuable as it is the first tool for the perceptual assessment of cleft palate speech in Zulu. The research methodology may serve as an example for the development of similar speech assessment protocols for children with cleft palate in other African languages.

Die doel van hierdie studie was om ‘n betroubare en geldige Zoeloe persepsuele spraak assesseringsprotokol vir voorskoolse kinders met gesplete lip en verhemelte te ontwikkel gebasseer op die internasionale riglyne (www.eurocran.org). Die kliniese toepaslikheid en relevansie van die internasionale riglyne vir die persepsuele assessering van gesplete lip en verhemelte is bepaal. Die doelwitte is bereik deur ‘n gemengde kwalitatiewe en kwantitatiewe navorsingsmetode te volg asook deur die navorsing in vier fases uit te voer. In fase een is die protokol ontwikkel met die bystand van ‘n Zoeloe taalkundige, in fase twee is die protokol getoets op 12 normale Zoeloe-sprekende kinders tussen drie en ses jaar, in fase drie is die persepsies van drie spraak-taalterapeute verkry aangaande die kliniese toepaslikheid van die protokol na afloop van evaluasies op 12 Zoeloe-sprekende voorskoolse kinders met gesplete lip en verhemelte tussen drie en ses jaar, in fase vier is gereflekteer op die toepaslikheid van die internasionale riglyne vir Zoeloe. ‘n Kritiese analise van die protokol het aangedui dat die internasionale riglyne (www.eurocran.org) gebruik kon word om ‘n persepsuele spraak assesseringsprotokol in ‘n Afrika taal, naamlik Zoeloe, op te stel. Resultate van die voorstudie het aangedui dat die protokol taal-, ouderdoms- en kultureel toepaslik was vir die normale Zoeloe-sprekende voorskoolse kinders. Die spraak-taalterapeute as deelnemers het aangedui dat die protokol klinies toepaslik was vir voorskoolse kinders met gesplete lip en verhemelte in terme van die kulturele sensitiwiteit van die protokol, administrasie tyd asook die vermoë om die spesifieke gesplete lip en verhemelte spraakkenmerke te ontlok. Die internasionale riglyne (www.eurocran.org) kon gevolg word vir Zoeloe met insluiting van die suigklanke in die Zoeloe taalstruktuur. Die resultate het implikasies vir dienslewering in Suid-Afrika met betrekking tot gesplete lip en verhemelte. Hierdie implikasies sluit in-diens opleiding van spraak-taalterapeute in om aan hul riglyne te verskaf vir beste praktyk. Implikasies vir verdere navorsing omsluit die ontwikkeling van norme in terme van die spraak ontwikkeling in Zoeloe asook die moontlike standardisering van die persepsuele spraak asesseringsprotokol. Die studie is waardevol aangesien dit die eerste poging was om ‘n persepsuele spraak assesseringsprotokol in Zoeloe te ontwikkel vir die evaluasie van kinders met gesplete lip en verhemelte. Die navorsingsmetodologie kan gevolg word vir die ontwikkeling van soortgelyke spraak assesseringprotokolle vir kinders met gesplete lip en verhemelte in ander Afrika tale.

The need for a standard approach for the diagnosis of speech disorders, in particular resonance disorders associated with cleft lip and/or palate, has been recognised. A reliable and valid measure of nasality is important, because it not only affects clinical decision making but is also essential for the evaluation of treatment outcomes. In order to allow cross-linguistic comparisons of the assessment of resonance, language specific stimuli developed according to a common set of guidelines have been recommended. The aim of this thesis was to contribute to the development of an assessment protocol for use in Malay speaking individuals with clefts of the lip and/or palate, specifically focusing on the detection of nasality. A series of four studies were completed which systematically developed and then validated a set of stimuli in the Malay language using both perceptual and instrumental measures.In the first study, three stimuli were developed for the assessment of nasality based on both the proportion of nasal phonemes in typical conversation samples in Malay and guidelines from the current international literature. The phonetic content of the stimuli were comparable to similar passages used in English and comprised of an Oral Passage, a Nasal Passage and a Set of Sentences.
In the second study, the stimuli constructed were tested in a large number of typically developing (non-cleft) Malay speaking children using both instrumental and perceptual methods of assessment. The results of this study provide the first set of normative data of nasalance scores for the three newly developed stimuli. The mean nasalance score for the Oral Passage was 13.86% (SD = 5.11, 95% CI = 13.04–14.68), 60.28% (SD = 6.99, 95% CI = 59.15–61.41) for the Nasal Passage, and 27.72% (SD = 4.74, 95% CI = 26.96–28.49) for the Set of Sentences. These scores were significantly different from each other suggesting that they can be used to detect the different types of resonance disorder in speech (e.g. hypernasality and/or hyponasality).
In the third study, the stimuli were validated in a sample of Malay speaking children with cleft of the lip and/or palate and compared with a control population. Nasality was measured using perceptual evaluation and nasometry. The results suggested that the Oral Passage and Set of Sentences developed in Malay were valid measures for detecting hypernasality for both perceptual evaluation of nasality, and for nasometry. Due to the small number of participants that were hyponasal, the validity of the Nasal Passage could not be determined.
For nasometry to be clinically relevant threshold values that indicate abnormal nasality are required. The threshold values for each of the stimuli were first ascertained after obtaining typical nasality levels from a group of healthy Malay speaking children and then tested in a sample of cleft and non-cleft Malay speaking children. In contrast to the nasalance cutoffs obtained from typical Malay speaking children, the cutoffs obtained from the cleft children yielded better outcomes for detecting resonance disorders. The cutoffs were: ≥ 22% for the Oral Passage (sensitivity = 0.91, specificity = 0.93, overall efficiency = 0.92), ≥ 30% for the Set of Sentences (sensitivity = 0.96, specificity = 0.85, overall efficiency = 0.88) and ≤ 39 on the Nasal Passage (sensitivity = 1.00, specificity = 0.99, overall efficiency = 0.99).
Finally, the fourth study explored the application of recently developed techniques for assessing nasality using spectral voice analysis and compared these results with nasometry using a sub-sample of Malay speaking children from the third study. The participants were children with cleft lip and/or palate with perceived hypernasality and a group of healthy controls perceived to have normal resonance. The potential of assessing nasality using vowels, which ideally can be an easier option to administer clinically and have minimal impact on language and literacy skills, were investigated.
The findings showed that only the one-third-octave analysis method could be successfully used to detect hypernasality in the cleft population compared to the VLHR method. Using the one-third-octave analysis, the spectral characteristics of nasalised vowel /i/ taken from /pit/ and /tip/ showed an increase in amplitude in F1, between F1 and F2 regions. The amplitude of the formants at F3 region was lower in the cleft group but did not differ from the control group as reported in previous studies. Although, the one-third-octave analysis has some potential in detecting hypernasality, the accuracy of the analysis compared to perceptual ratings of nasality was only moderate. Compared to nasometry, the diagnostic value of the one-third-octave analysis in detecting hypernasality was lower.
The overall findings suggest that, except for the Nasal Passage, the Oral Passage and the Set of Sentences developed in Malay using this systematic approach were culturally appropriate and valid for the assessment of nasality. Furthermore, by comparing two instrumental methods (nasometry and spectral analysis) with perceptual evaluation in a large number of cleft and typically developing children, the present thesis was able to demonstrate the clinical benefits of two recently proposed methods of spectral voice analyses and compare them to existing methods. Compared to spectral analysis, nasometry remains a superior method for assessing nasality. Threshold values that indicate abnormal nasality levels for the newly developed stimuli in Malay have been recommended.

The research presents nuclear issue as the study of the conversion of bibliographic records process. Delimiting the object of study for understanding the conversion of analog bibliographic records to MARC 21 Bibliographic format, from the syntactic and semantic analysis of records described in patterns of descriptive metadata structure and content standards. The thesis of this research is that the syntactic and semantic principles of bibliographic records, defined by schemas describing and cataloging the display, in the standards of descriptive metadata structure and content standards, determine the process of converting bibliographic records MARC21 Format for Bibliographic. Based on this context, the proposition of this research is to develop a theoretical study of the syntax and semantics of bibliographic records, by the Linguistic bias, with Saussure and Hjelmslev, which subsidize the conversion of analog bibliographic records to MARC 21 Format for Bibliographic a computational interpreter . With this proposal, it is stated, as a general goal, develop a theoretical-conceptual model of syntax and semantics in bibliographic records from Saussureano hjelmslevianos and linguistic studies of the manifestations of human language, which is applicable to a computational interpreter aimed to conversion bibliographic records to MARC 21 Bibliographic format. To reach this goal it is through the following specific objectives, divided in two groups and directed respectively to the theoretical-conceptual model of syntactic structure and semantics of bibliographic records, and the conversion of their records process: explain the relationship between syntax and semantics of bibliographic in the light of linguistic aspects studied by Saussure and Hjelmslev, applicable to analog and digital media records; submit characteristic principles of syntax and semantics in bibliographic records; look through the available literature, the methods and procedures for conversion of bibliographic records to MARC 21 Bibliographic format; set method of image processing bibliographic records in analog optical character recognition (OCR) software; present computational interpretation technique that is focused on the conversion of analog bibliographic records to MARC 21 Bibliographic Format to consider the syntactic and semantic schemas. In view of the outlined objectives, the methodological approach of the research is based on a qualitative approach, exploratory, descriptive and experimental basis and uses the literature. As a result, it is expected to contribute significantly to the Information Science Similarly, considering social, inherent in human knowledge and the solution of the problem presented aspects. The greatest social benefit occasioned by this research relates closely, the aspects of sharing bibliographic records, and the possibility of extending access to the metadata of information resources represented by the various units of information. Contributions theoretically can be glimpsed on the development of issues related to syntactic and semantic aspects of bibliographic records, and involve, at one time, the interdisciplinary Information Science, Computer Science and Linguistics. Contributions in the practical field are identified by the study include the development of Scan for MARC, a computational interpreter that can be adopted by any institution wishing to make use of conversion databases of bibliographic records procedure, to MARC21 format Library from the description and visualization of bibliographic records (AACR2R and ISBD), that character is considered innovative research schemes.

The study examines preconditions to adopt semantic web technologies for a novel specialized medium of scholarly communication that – also interdisciplinary – enables the synchronicity of publication and knowledge representation on the one hand and the dynamic bundling of assertions on the other hand. Therefore it is first of all necessary to determine a concept of „(scholarly) publication“ and of neighbouring concepts. These considerations are fertilized by theories that can be related to the radical constructivism. Therefrom derives a critique of the mainstream of knowledge representation that resigns to being not able to represent the dynamics of knowledge. Finally the study evinces a conceptual outline of a technical system that is built upon the known concept of nanopublications and is called „scholarly network“. The increased effort while publishing in the scholarly network is outweighed by the benefits of this publication medium: It may help to render research outputs more precisely as well as to raise their connectivity through reducing the complexity of assertions. Beyond that it would generate an openly accessible and finely structured discourse archive – a wide participation provided.
