Projeto de Pós-Graduação/Dissertação apresentado à Universidade Fernando Pessoa como parte dos requisitos para obtenção do grau de Mestre em Medicina DentáriaUm dos principais objetivos do tratamento Endodôntico é a tentativa de conseguir conduzir o sistema de canais radiculares a um ambiente de assepsia, sendo este conseguido através da eliminação dos microrganismos nocivos à cicatrização dos tecidos, permitindo assim a cura da infeção e posterior restabelecimento da função do dente. O tratamento endodôntico, seja preconizado numa ou em múltiplas sessões, visa a criação de condições ótimas para a obturação e selamento tridimensional dos canais radiculares. Assim, a seleção da modalidade de tratamento endodôntico terá de se basear, primeiramente, numa avaliação rigorosa do dente, propriamente dito, quanto à sua condição fisiopatológica pulpar e periapical, acessibilidade, caraterísticas morfológicas dos canais radiculares e restaurabilidade Uma das questões que mais se tem debatido é se o tratamento endodôntico numa sessão, possibilita que se atinjam tais condições, permitindo, portanto, alcançar os objetivos biológicos e mecânicos exigidos. Neste contexto, em que na atualidade paira a controvérsia e a incerteza sobre qual o procedimento mais indicado para a prática clínica, o objetivo deste trabalho foi, após efetuar uma revisão da literatura científica existente, tentar perceber se é mais indicado iniciar o tratamento e finaliza-lo na mesma sessão ou proceder a obturação na consulta seguinte. Hoje, devido aos avanços das técnicas de instrumentação e irrigação, que tem tornado o tratamento endodôntico mais eficaz num menor período de tempo, a sessão única é cada vez mais preconizada pelos profissionais. O sucesso será garantido se os procedimentos clínicos forem integralmente cumpridos e o tipo de modalidade escolhida resultar da reflexão das características de cada caso em particular. One of the main goals of Endodontic treatment is the attempt to achieve leading the root canal system to an aseptic environment, which is achieved through the elimination of the microorganisms that are harmful to the healing of tissues, allowing this way the healing of the infection and subsequent restoration of the tooth function. Endodontic treatment, whether recommended in one or in multiple sessions, aims to create optimal conditions for the tridimensional filling and sealing of the root canals. Thus, the selection of the type of endodontic treatment must be based, first, in a rigorous evaluation of the tooth itself, as far as its pathophysiological pulp and periapical condition, accessibility, morphological characteristics of the root canals and restorability are concerned. One of the most discussed issues is whether endodontic treatment in one session, enables one to get such conditions that allow the required mechanical and biological objectives to be achieved. In this context, in which nowadays hangs the controversy and the uncertainty about what the most suitable procedure for clinical practice is, the aim of this work, after carrying out a review of the existing scientific literature, was trying to understand whether it is more appropriate to start treatment and finish it in the same session or proceed with the filling in a second session. Today, due to the advances in the instrumentation and irrigation techniques, which have turned the endodontic treatment in a shorter period of time most effective, a Single Visit is increasingly recommended by health professionals. The success will be ensured if the clinical procedures are fully performed and if the type of modality chosen results of the reflection of the characteristics of each particular case.

My work concerns the divergent narratives created by fusing varied, often conflicting, textures, colors and fabrics, into a tenuous order. I intend for these otherwise clashing materials to create drama that is simultaneously enthusiastic, epic and ambiguous. While this media's formal properties re an important component of my work, the material's cultural and art-historical associations are also are critical ingredient. In this thesis, I will explore the use of the varied collage material, hierarchical compositions and contemporary influence of 19th Century Romantic themes as they relate to forming a variety of distinctly contemporary narratives in my compositions. I will investigate how my artistic point-of-view is informed by art-history, irony and the work of contemporary painters. Finally, I will discuss how my work engages a contemporary version of the Sublime.

Este estudo teve como objectivo avaliar a eficácia de uma sessão de informação a propósito de uma intervenção cirúrgica com anestesia geral na redução da ansiedade em jovens com idades compreendidas entre os 6 e os 12 anos. A amostra foi constituída por 125 jovens, 62 do sexo masculino e 63 do sexo feminino. Foram constituídos dois grupos, em que ao grupo experimental foi administrado um programa de informação sobre procedimentos cirúrgicos com anestesia geral, utilizando técnicas de modelagem, e em que ao grupo de controlo apenas foi aplicada a sessão avaliativa. Os resultados obtidos permitiram concluir que a eficácia da sessão informativa a propósito de uma intervenção cirúrgica com anestesia geral na redução da ansiedade, nas crianças, foi comprovada.
The aim of this study was to evaluate the efficacy of an information session about cirurgy, with general anesthesia induction, in reducing anxiety in children from 6 to 12 years undergoing cirurgy. Our sample was constituted by 125 children, 62 boys and 63 girls divided in two groups: the experimental group had an information session about chirurgical procedures with general anesthesia and had anxiety evaluated pre and post session, as the control group had only one anxiety evaluation. The results show that the session was effective on reducing pre-operatory anxiety in children.

Até o início da década de 1960, as sessões de cinema da capital catarinense eram batizadas com títulos diversos, identificando a que grupos estavam endereçadas. Nas crônicas escritas na cidade, a mais citada é a Sessão das Moças, que tinha lugar no Cine Ritz, no Centro de Florianópolis, entre 1943 e 1962, a qual figurava no calendário de lazer ilhéu. A sessão pode ser compreendida como um misto de construtora de redes de sociabilidades e espaço pedagógico, pois projetava representações de ser, agir e sentir possíveis de serem apropriados pelas/os espectadoras/es. Ao lado de imagens de moda e beleza, os filmes exibidos na sessão exploravam representações do amor romântico em todas as suas etapas: do inesperado primeiro encontro ao casamento redentor. Ademais, as temáticas estressavam as lições envolvendo a moral, a valorização da família e a contenção das pulsões.

This dissertation studies a type theory to guarantee communication-safety in sessions of an arbitrary number of participants, typically represented as communication patterns, of mobile processes in the context of multiparty session types— a well-established type theory that describes the interactive structure of a fixed number of processes from a global point of view and type-checks the processes through projection of the global type onto the participants of the session. Communication-safety is the property that mobile processes exchange values of the same set without deadlocking and data races. Our study introduces a programming idiom of roles— a concept that describes the nature of a communication pattern in a similar way to classes in Java and C#, offering a design on how to incorporate parameterised session types into a mainstream language. The formal model (1) preserves multiparty session types’ syntax and type-checking strategy, and (2) allows the number of participants to range over infinite sets of natural numbers, providing full computation power of programs. A series of communication patterns and real-world examples from parallel algorithms and data exchange protocols demonstrate the expressiveness and practicality of the formal model, comparing the model with the only mature implementation of (binary) session types. We proved that type preservation under reduction and communication-safety hold in the type system. The study of parameterised session types is supported by the examination of multiparty session types for synchronous communications. We extended the initial work on multiparty session types with a simpler calculus, multicast send of values and labels, a practical form of higher-order communication and a more intuitive, elegant linearity property; we proved that (a) type preservation and communication-safety hold in the type system, and (b) interactions of a typeable process follow exactly the description of the global type.

Повний текст джерелаАнотація:
Behavior analysts refer to a decrease in response rate following repeated, contingent presentations of a reinforcing stimulus as a product of satiation. Other evidence suggests that these decreases may often be due to habituation to the sensory properties of the reinforcing stimulus. The investigation reported here sought to determine whether decreases in operant responding by 3 adults with developmental disabilities were due to satiation or habituation. During baseline, participants placed poker chips into a container, and no reinforcement was available. Within subsequent phases, participants received diet lemon-lime soda on a fixed-ratio (FR) schedule of reinforcement. In one condition, the color of the soda was constant throughout the session, and in another condition food coloring was added several minutes into the session. Results for at least 2 participants indicated that: (a) soda functioned as a reinforcer for placing poker chips in the can; (b) response rates decreased within the session to baseline levels; and (c) response rates increased following a change in the color of the soda within the session. Results for the third participant were less clear. The results support the argument made by other researchers that the terms habituation (a weakening of a behavior following contact with the reinforcing stimulus) and stimulus specificity (a strengthening of a behavior following a change in the reinforcing stimulus) may be more appropriate descriptors of within-session changes in responding. The factors associated with habituation and satiation, as well as both basic and applied research examples, are discussed.

O Sistema Multidimensional de Categorização de Comportamentos na Interação Terapêutica (SiMCCIT) desenvolvido por Zamignani e Meyer em 2007 pretende descrever o que ocorre em sessões de psicoterapias por meio de categorias de comportamentos de terapeutas e clientes. A pergunta que o presente estudo pretendeu responder é se o eixo correspondente ao comportamento verbal vocal desse sistema é capaz de identificar diferenças entre terapias bem e mal sucedidas quando aplicado às quartas sessões. A avaliação das terapias foi feita com um critério misto definido por: a) os resultados do Inventário de Aliança Terapêutica (WAI), b) presença de comportamentos de melhoras e de análise e c) relato de outras mudanças de comportamentos do cliente. De um total de 25 terapias com as quatro primeiras sessões gravadas em áudio, seis foram consideradas bem sucedidas, seis mal sucedidas e 13 foram consideradas terapias com resultados intermediários. Foi realizada a categorização da quarta sessão das terapias bem sucedidas e das terapias mal sucedidas. Os dados sugerem a existência de algumas diferenças entre as sessões das terapias bem e mal sucedidas, embora não significativas estatisticamente. Nas sessões das terapias bem sucedidas observou-se que: a categoria Solicitação de Relato tendeu a ser um pouco mais frequente em todos os casos; a categoria Solicitação apresentou uma porcentagem discretamente maior e ocorreu uma correlação positiva entre facilitação e empatia. Nas sessões das terapias mal sucedidas constatou-se que: a categoria relato ou foi menos frequente ou mais frequente que nas sessões das Terapias Bem Sucedidas; quanto mais os clientes relatavam mais os terapeutas facilitavam seus relatos e que quanto mais os terapeutas solicitavam reflexões, mais metas os clientes se propunham a realizar. Como as diferenças da categorização não foram estatisticamente significativas em casos julgados diferentes concluiu-se que o eixo de comportamento verbal vocal do SiMCCIT diferenciou pouco as terapias bem e mal sucedidas. Algumas variáveis dificultaram a observação da capacidade do sistema de diferenciar as sessões das terapias bem e mal sucedidas: o número reduzido da amostra e o uso de apenas um dos eixos do sistema. Discutiu-se assim a necessidade de ampliar a amostra e utilizar outros eixos do sistema, como o de temasThe Multidimensional System for coding Behaviors in Therapist-Client Interaction (SiMCCIT), developed by Zamignani and Meyer, intend to describe what happens in psychotherapy sessions using behavioral categories of therapists and clients. The question that this study intended to answer was if this system is able to identify differences between successful and unsuccessful therapies. The assessment of therapy success was made with a mixed criterion defined by: (a) the results of the Working Alliance Inventory (WAI); (b) presence of improved behavior and analysis and (c) report of other changes in client behavior. In the total of 25 therapies with the first four sessions audio recorded, six were considered successful, six unsuccessful and 13 intermediate. The fourth sessions of successful and unsuccessful therapies were categorized. The data suggest some differences between the successful and unsuccessful therapy sessions, although not statistically significant. In the successful therapy sessions it was noted that: the category Request Report tended to be slightly more frequent in all sessions, the category Request showed a slightly higher percentage, and there was a positive correlation between Facilitation and Empathy. In the sessions of unsuccessful therapies it was found that: clients reported more or less than in successful therapies, the more clients reported more therapists facilitated their reports and that the more therapist asked reflections, the more goals clients proposed to undertake. Because the differences in categorization were not statistically significant in cases considered different it was concluded that the axis of vocal verbal behavior of SiMCCIT did not differentiate the successful from unsuccessful therapies. Some variables hampered the ability of the system to differentiate between sessions of successful and unsuccessful therapies: the reduced number of the sample and the use of only one of the axes of the system. It was discussed the need to expand the sample and use other axes of the system, such as themes

While a significant amount of research illustrates the overall positive effects of therapists' general use of mindfulness, very few studies have addressed whether therapists' use of mindfulness translates to improved psychotherapy outcomes. The present study utilized a randomized-controlled design to test whether a brief mindfulness training program and pre-session mindfulness practice could have a positive impact on therapy; in particular, we hypothesized that mindfulness training and practice would improve ratings on therapeutic presence as rated by clients and therapists and session effectiveness as rated by clients. The present study also examined whether clients' subjective ratings of therapy outcome and therapists' theoretical orientation impacted outcome measures after therapists completed mindfulness training. The 20 participating therapists were randomly assigned to either the mindfulness training (MT) group or control group according to a computer generated randomization list. Results indicated that clients did not significantly improve on outcome measures after completing the mindfulness training. Clients' subjective ratings on a psychotherapy outcome measure did predict changes in their ratings of therapeutic presence. This finding may have important implications for future research examining client characteristics that may moderate the relationship between therapeutic presence and session outcomes. Limitations of the present study and future directions are discussed.

A brain computer interface (BCI) is a system to interpret a user’s intentionthrough using the users brain activity. The system is todayforemost used for research for disabled people. Electroencephalography(EEG) is the most common method used by BCI to record the brainactivity of the user, where the relevant information is read from thebeta and mu waves in the brain. These brain waves are from the partof the brain that is activated when user are doing problem solving orimagining moving a part of the body.This report will investigate EEG-data taken from test subjects imaginingto move left or right arm. To investigate the data from the EEG,two of the most common classification models, Multi-Layer Perceptron(MLP) and Support Vector Machines (SVM), will be used. The investigationwill show how well the models performs in session-to-sessiongeneralisation, which means we will evaluate the performance of theclassifier when testing the it on data from another session than the sessionit was trained on.The tests shows that the SVM, with the Gaussian Radial BasisFunction (RBF) as kernel, yielded the best results. For every personthere is three sessions, EEG data required at three separate occasions,that were used in the tests and, for the SVM, it is clear that trainingon the first two sessions combined and testing on the last session gavethe best classification of the EEG data. However, for the MLP thedifferences in results, from training on one session or two, smaller.

High data rate wireless packet data networks have made real-time IP based services available through mobile devices. At the same time, differences in the characteristics of radio technologies (802.11/WiFi and 3G networks) make seamless handoff across heterogeneous wireless networks difficult. Despite this, many believe that the ultimate goal of next generation networks (often referred to as the fourth generation) is to allow convergence of such dissimilar heterogeneous networks. Supporting voice over Internet Protocol in next-generation wireless systems is thought by some to require support for mobility and quality of service features. Currently a mobile node can experience interruptions or even sporadic disconnections of an on going real-time session due to handovers between both networks of different types and networks of the same type. Many tests have already been done in this area and one may wonder why it is worth spending even more time investigating it? This thesis focuses on the important problem of providing session security despite handovers between networks (be they operated by the same operator or different operators and be they the same link technologies or different). One of the goals in this thesis is to investigate how an ongoing speech session can continue despite a change in transmission media1. Additionally, a number of security threats that could occur due to the handover will be identified and presented. Finally, the most suitable solution to address these threats will be tested in a real environment. Eventual shortcomings and weaknesses will be identified and presented; along with suggestions for future work. 1 When utilizing IP over carriers such as wired Ethernet, WLAN, and 3G.Trådlösa hög-hastighets datanät har möjliggjort appliceringen av realtids tjänster på mobil utrustning över IP. Samtidigt har skillnaderna i de olika radioteknologierna (802.11/WiFi och 3G näten) introducerat nya problem med att upprätthålla trådlösa kommunikationen tvärs den heterogena trådlösa accessen. Många tror att slutmålet för nästa generations nätverk (ofta refererade som fjärde generationens nätverk) är att tillåta konvergensen av dessa olika heterogena nätverk. Stödet för Voice over Internet Protokollet (VoIP) i nästa generations trådlösa nät tror somliga kräver ett inslag av kombination mellan mobilitet samt upprätthållandet av kvaliteten. För närvarande kan den mobila noden (MN) råka ut för störningar och även sporadiska avbrott av en pågående realtidssessionen på grund av övergångar mellan samma eller olika typer av medier. Många tester har redan gjorts inom det här området och man kan fråga sig varför det är värt att lägga ner ännu mer tid på att undersöka det här? Det här examensarbetet fokuserar på det viktiga problemet som handlar om att kunna erbjuda sessions säkerhet trots övergångar mellan näten (oavsett om dessa drivs av samma eller olika operatörer samt oavsett om de är av samma eller olika nätverks typ). Ett av målen för det här examensarbetet är att undersöka hur en pågående talsession behålls vid byte av transmissionsmedia2. Vidare kommer olika säkerhetsaspekter och hot som kan tänkas uppstå vid bytet att identifieras och presenteras. Slutligen kommer den mest lämpade lösningen till problemet att testas i verklig miljö. Eventuella brister och svagheter kommer att identifieras och redovisas i slutet av rapporten tillsammans med förslag på framtida arbete. 2 Då man nyttjar IP bärare som trådbundet Ethernet, WLAN och 3G.

Actualmente se crean, almacenan, editan y distribuyen grandes cantidades de contenidos audiovisuales, en parte debido a la capacidad de almacenamiento prácticamente ilimitada, al acceso a los medios necesarios por todo el mundo y en cualquier parte, y a la ubicua conectividad proporcionada por Internet. En este contexto, se requiere una gestión adecuada y sostenible que permita la búsqueda y recuperación de la información de interés. Es aquí donde las técnicas de procesamiento del habla juegan un papel crucial en el etiquetado y anotación automáticos de contenidos audiovisuales.
La diarización de locutores es un proceso de apoyo clave para otros sistemas de procesamiento del habla, tales como el reconocimiento automático del habla y el reconocimiento automático de locutores, frecuentemente usados para la extracción automática de metadatos de documentos hablados.
Entre las distintas colecciones de contenidos, puede haber locutores recurrentes que participen en diferentes sesiones dentro de una colección determinada (por ejemplo, en contenidos de televisión y radio). Dada la naturaleza local de la tecnología de diarización de locutores, un locutor recurrente arbitrario probablemente recibirá identificadores locales diferentes entre las distintas sesiones donde tal locutor participa. En esta situación tendría más sentido que los locutores recurrentes recibieran el mismo identificador abstracto, global para todas las sesiones. Esta tarea se conoce como diarización de locutores inter-sesión.
La diarización de locutores actual ha conseguido muy buena precisión, pero normalmente al coste de largos tiempos de ejecución. Esta limitación podría no ser adecuada para aplicaciones de la vida real a gran escala, se hace aún más evidente el la tarea de diarización de locutores inter-sesión.
En esta tesis, la aproximación a la diarización rápida de locutores basada en claves binarias se lleva a un siguiente nivel, con el objetivo de obtener rendimientos similares a los de los sistemas actuales punteros, mientras se preservan altas tasas de velocidad que permitan el tratamiento de grandes colecciones de audio en tiempos competitivos. Además, se propone un nuevo sistema de diarización de locutores inter-sesión basado en claves binarias que sigue los mismos principios previamente establecidos: precisión competitiva en tiempos de ejecución cortos. Como resultado de esta tesis, se propone un sistema mejorado de diarización que consigue una mejora relativa del 16% en rendimiento con respecto a un sistema base de claves binarias (15% DER frente a un 18.22% DER, siendo DER la tasa de error de diarización), siendo 7 veces más rápido (0.035xRT frente a 0.252xRT, siendo xRT el factor de tiempo real) y 28 veces más rápido que el tiempo real. En cuanto a la diarización inter-sesión, en esta tesis se propone un sistema binario cuya precisión es solo levemente inferior (3.5% DER absoluto) a la de su sistema homólogo para sesiones independientes, mientras que presenta factores de tiempo real alrededor de 0.036xRT. Además, la aproximación propuesta escala adecuadamente para tratar colecciones de audio de varios cientos de horas.Today, massive amounts of audiovisual content are being generated, stored, released and delivered, in part due to the virtually unlimited storage capacity, the access to the necessary media to produce them by anybody and anywhere, and the ubiquitous connectivity provided by the Internet. In this context, suitable, affordable and sustainable content management which enables searching and retrieving information of interest is a must. Since manual handling of such amount of data is intractable, it is here where speech processing techniques may play a crucial role in the automatic tagging and annotation of audiovisual content. The task of speaker diarization (also known as the “who spoke when” task) has become a key process as a supporting technology for further speech processing systems, such as automatic speech recognition and automatic speaker recognition, used for the automatic extraction of metadata from spoken documents. Among the massive amount of audiovisual content being created, there can be recurrent speakers who participate in several sessions within a collection of audiovisual sessions. For instance, in TV and radio content one can frequently find recurrent speakers such as public figures, journalists, presenters, anchors, and so on. Due to the local nature of current speaker diarization technology (systems work on a single-session basis), an arbitrary recurrent speaker will likely receive different local abstract identifiers among the different sessions where he/she participates. In this situation, it would be more meaningful that the recurrent speakers receive the same global, abstract ID along all sessions. This task is known as cross-session speaker diarization. Current state-of-the-art speaker diarization systems have achieved very good performance, but usually at the cost of long processing times. This limitation on execution time makes current systems not suitable for large-scale, real-life applications, and becomes even more evident in the task of cross-session speaker diarization. In this thesis, the fast speaker diarization approach based on binary key speaker modeling is taken to a next level with the aim of bringing it closer to state-of-the-art performance while preserving high speed rates that enable the processing of large audio collections in competitive times. Furthermore, a new cross-session speaker diarization system based on binary key speaker modeling is proposed by following the same previously established goals: competitive performance with short execution times. As a result of this thesis, we propose a new improved single-session speaker diarization system which exhibits a 16% relative improvement in performance with regard to a baseline binary key system (15.15% DER opposed to 18.22% DER, being DER the diarization error rate), while being 7 times faster (0.035xRT against 0.252xRT, being xRT the real-time factor) and 28 times faster than real time. As for cross-session speaker diarization, in this thesis we propose a binary system whose performance is just slightly below (3.5% absolute DER) the performance of its single-session counterpart, while presenting a real-time factor of 0.036xRT. Furthermore, our approach has been shown to successfully scale for processing audio collection of several hundreds of hours.

En el campo de los sistemas distribuidos, lograr la coordinación entre diversas unidades de cómputo y sub-sistemas es una tarea compleja, pues cada unidad de computo se comporta distinta a las demás, de forma concurrente y de manera descentralizada. Con el fin de expresar como diversas unidades de computo se comunican unas con otras, se utilizan definiciones de protocolos. Session types son una disciplina de tipos que permite lograr la coordinación entre muchos participantes de un sistema distribuido, mediante la definición de un protocolo coreográfico. La disciplina de tipos impone condiciones sobre la coreografía con el fin de asegurar que el sistema distribuido que la implementa se comporta de la forma en la que fue definido y además posee garantías sobre propiedades de la comunicación. Entre las propiedades importantes se encuentran la ausencia de: deadlocks, mensajes huérfanos y recepciones inesperadas de mensajes. La coreografía es expresada como una entidad global, la cual es projectada a distintos tipos, uno para cada participante involucrado en la coreografía. Dichos tipos son usados para un proceso de typecheck que verifica que las implementaciones de las unidades distribuidas, llamadas procesos, se comportaran en la interacción global como se espera. Se muestra que lograr modularidad en session types no es trivial. Para ello, se presenta un caso de estudio en el que el uso de definiciones modulares para session types introduce problemas en el comportamiento global luego de su composición. Comenzando desde el caso de estudio, se explica como se introducen dichos problemas al componer sub-sessiones. Se muestra como los problemas globales pueden ser evitados gracias al uso de un mecanismo de composición que se basa en interacciones de bloqueo entre participantes. En este trabajo se desarrolla una extensión de un sistema de tipos que permite la composición modular de session types (MCST). MCST se basa en condiciones impuestas sobre definiciones modulares de sub-sessiones, además de un sistema de tipos que permite verificar sub-sessiones por separado, y un mecanismo de composición que produce sistemas bien formados. La solución presentada es modular, dado que mantiene sus definiciones separadas con el fin de reusarlas. Las condiciones para verificar correctitud no dependen del contexto en el cual una sub-session es llamada.El mecanismo de composición reusa conceptos de inlining y composición con ciclos de trabajos previos, haciéndolas aplicables en más casos, lo que resulta en un sistema más expresivo. MCST mantiene las garantías de comunicación de session types mencionadas previamente. Ademas, MCST mejora la expresividad de session types, dado que la nueva disciplina de tipos con el mecanismo de composición permite definir coreografías que no son permitidas en el estado del arte de session types.

Previous issue date: 2006-03-24Studies indicate that couples with or without conflicts have precisely the same types of problems, and that what differentiates them, are their abilities of communication and solution of problems. Although some investigators treat training and problem solving training as one module, the two types of training are quite different as to what concerns procedure and concept. Considering that many clients that look for therapeutic help only attend an single session, and that couples are more demanding concerning the speed of results, any progress obtained in the first session could contribute to treatment adherence or could even be the only chance the therapist has to promote significant changes in the couple's life. The general objective of the present project was to explore the effects of two interventions in single sessions of couple therapy, one focusing on communication and the other on problem solving. Six couples participated in the study, divided in two groups: one group receiving the communication-focused intervention (group A) and another receiving the problem solving focused intervention (group B). The results of group A suggest that it is possible, with a single session, to effectively improve the communication of the couple. However, the teaching of problem solving strategies did not result in improvement. More studies are necessary to improve the techniques. single session couple therapy, communication and problem solving training.
Estudos indicam que casais com ou sem conflitos parecem ter precisamente os mesmos conjuntos de problemas, sendo o que os diferenciam, entre outros fatores, as habilidades de comunicação e solução de problemas. Apesar de alguns investigadores tratarem o treinamento de comunicação e solução de problemas como um único módulo, os dois tipos de treino são bastante diferentes e podem ser distinguidos quanto ao procedimento e conceito. Considerando que muitos clientes que buscam ajuda terapêutica só assistem a uma única sessão, e que casais são mais exigentes quanto a rapidez dos resultados, uma intervenção que necessitasse de apenas uma sessão para produzir mudanças no relacionamento poderia contribuir para a aderência ao tratamento, ou para promover mudanças significativas na vida do casal. O objetivo geral dessa pesquisa foi explorar os efeitos de duas intervenções em sessões únicas de casal, uma com enfoque na comunicação e a outra com enfoque na solução de problemas. Participaram do estudo seis casais, divididos em dois grupos: um de enfoque na comunicação (grupo A) e outro de enfoque na solução de problemas (grupo B). Os resultados sugerem que é possível, com uma única sessão, ensinar novas estratégias ao casal para que, melhorando sua comunicação, possa enfrentar melhor os problemas. Entretanto, são necessárias mais pesquisas para melhorar as técnicas de intervenção, e ampliar o seu alcance.

The Session Initiation Protocol (SIP) was designed for wire line networks. It was
developed to initiate, modify and terminate sessions between two hosts on a network.
When the Internet expanded to include wireless hosts, SIP did not scale well for these
wireless hosts because of the nature of the wireless channel. Also, there were issues
with mobility and real time communication. This thesis proposes improvements to
some of the extensions to SIP, for better performance over wireless channels. We
investigate the call setup time for various transport mechanisms viz. TCP and UDP,
and study the performance of a dynamic Session Timers compared to the current
standard of a periodic refresh mechanism, where the frequency of UPDATEs vary with
the condition of the wireless channel. We also propose a handoff algorithm that
reduces the handover time with decreased packet losses.

In recent years, the most popular web search engines have excelled in their ability to answer short queries that require clear, localized and personalized answers. When it comes to complex exploratory search tasks however, the main challenge for the searcher remains the same as back in the 1990s: Trying to formulate a single query that contains all the right keywords to produce at least some relevant results. In this work we want to investigate new ways to facilitate exploratory search by making use of context information from the user's entire search process. Therefore we present the concept of session-based semantic search, with an optional extension to collaborative search scenarios. To improve the relevance of search results we expand queries with terms from the user's recent query history in the same search context (session-based search). We introduce a novel method for query classification based on statistical topic models which allows us to track the most important topics in a search session so that we can suggest relevant documents that could not be found through keyword matching. To demonstrate the potential of these concepts, we have built the prototype of a session-based semantic search engine which we release as free and open source software. In a qualitative user study that we have conducted, this prototype has shown promising results and was well-received by the participantsDie führenden Web-Suchmaschinen haben sich in den letzten Jahren gegenseitig darin übertroffen, möglichst leicht verständliche, lokalisierte und personalisierte Antworten auf kurze Suchanfragen anzubieten. Bei komplexen explorativen Rechercheaufgaben hingegen ist die größte Herausforderung für den Nutzer immer noch die gleiche wie in den 1990er Jahren: Eine einzige Suchanfrage so zu formulieren, dass alle notwendigen Schlüsselwörter enthalten sind, um zumindest ein paar relevante Ergebnisse zu erhalten. In der vorliegenden Arbeit sollen neue Methoden entwickelt werden, um die explorative Suche zu erleichtern, indem Kontextinformationen aus dem gesamten Suchprozess des Nutzers einbezogen werden. Daher stellen wir das Konzept der sitzungsbasierten semantischen Suche vor, mit einer optionalen Erweiterung auf kollaborative Suchszenarien. Um die Relevanz von Suchergebnissen zu steigern, werden Suchanfragen mit Begriffen aus den letzten Anfragen des Nutzers angereichert, die im selben Suchkontext gestellt wurden (sitzungsbasierte Suche). Außerdem wird ein neuartiger Ansatz zur Klassifizierung von Suchanfragen eingeführt, der auf statistischen Themenmodellen basiert und es uns ermöglicht, die wichtigsten Themen in einer Suchsitzung zu erkennen, um damit weitere relevante Dokumente vorzuschlagen, die nicht durch Keyword-Matching gefunden werden konnten. Um das Potential dieser Konzepte zu demonstrieren, wurde im Rahmen dieser Arbeit der Prototyp einer sitzungsbasierten semantischen Suchmaschine entwickelt, den wir als freie Software veröffentlichen. In einer qualitativen Nutzerstudie hat dieser Prototyp vielversprechende Ergebnisse hervorgebracht und wurde von den Teilnehmern positiv aufgenommen

Music EducationM.M.
The Irish singing session has provided a safe community where singers of all abilities are welcome to share with and learn from one another. Through British occupation and into independence, the Irish session has transformed tremendously from its original form. Still, the session carries on the Irish tradition of music learning and enculturation through oral transmission. Singing sessions provide a unique opportunity for the many songs of Irish history to be sung and learned; passed down from generation to generation! Singers learn new songs through listening to and watching other singers, imitating material, experimenting with new ideas, and discussing musical performances with others. Session leaders may attempt to create an encouraging and accepting environment where singers feel secure, resulting in the unbridled sharing of singers’ deep connections with a song. Such methods, including personal choice and a safe environment, have been observed through field research and have shown to positively affect singers and communities related to singing sessions in County Clare, Ireland. In this study, I pose that the methods used in singing sessions may also be beneficial when adapted for use in the music classroom.

Este trabalho propõe políticas para servidores Web baseados em sessões, visando ao oferecimento de garantias de qualidade de serviço (Quality of Service - QoS) a seus usuários. Para o fornecimento de QoS, dois tipos de políticas são consideradas: as responsáveis pela diferenciação de serviços e as responsáveis pelo controle de admissão. Alguns algoritmos de escalonamento foram desenvolvidos com o objetivo de oferecer melhores serviços para as sessões prioritárias: o algoritmo de escalonamento baseado em sessão (SBSA) e o algoritmo de escalonamento baseado em sessão com diferenciação de serviços (SBSA-DS). Quanto ao controle de admissão, foram consideradas duas novas políticas, as quais utilizam diferentes parâmetros para a tomada de decisão e têm como objetivo garantir a finalização do maior número de sessões prioritárias. A partir dos resultados obtidos nos experimentos realizados por meio de simulação, constatou-se que o emprego dos algoritmos e das políticas desenvolvidos melhora o atendimento das sessões para as quais deve ser oferecido um serviço preferencial. Portanto, em servidores Web preocupados com a garantia de QoS para seus usuários, os quais interagem com o sistema por meio de sessões, o uso dessas novas técnicas se mostra adequadoThis work considers policies for Web servers based on sessions, aiming at the guarantees of Quality of Service (QoS) to the systems users. Two types of policies are considered: the responsible for the differentiation of services and the responsible for the admission control. Some scheduling algorithms had been developed to offer better services for the priority sessions: the Session Based Scheduling Algorithm (SBSA) and the Session Based Scheduling Algorithm with Differentiation of Services (SBSA-DS). In relation to the admission control, two new policies had been considered, which use different parameters to help the decisions and have as objective guarantee the finalization of as many priority sessions as possible. From the obtained results of the experiments realized by mean of simulation, it is evidenced that the use of the developed algorithms and policies improves the attendance of the sessions that deserve preferential service. Therefore, in Web servers worried in the guarantee the QoS for their users, which interact with the system by sessions, the use of these new techniques reveals adequate

Este trabalho investiga as práticas discursivas de sessões de terapia de família de abordagem sistêmica. Enfoca a (re)construção dos sentidos desse discurso terapêutico, voltando-se para o que se convenciona chamar, dentro da área terapêutica, por re-significação e procurando olhar criticamente o pedido de ajuda do paciente e o ato de dar ajuda do terapeuta. Investigam-se também os lugares sociais/familiares dos sujeitos - aí incluída uma certa representação do terapeuta - quando em interação terapêutica. Partindo da noção de dialogismo proposta por Bakhtin e revisitada pelos estudos sobre a(s) heterogeneidade(s) enunciativa(s) de Authier-Revuz, são observadas, em diálogos extraídos de três sessões de terapia de família realizadas em institutos de ensino e pesquisa (duas instituições autônomas e uma autarquia federal), as fronteiras da alteridade, evidenciadas no gênero discursivo \"sessão de terapia\". Tal gênero discursivo, que, em sua superfície pode ser entendido como encontro com fins terapêuticos para discutir temas de conflitos humanos em situação relacional, evidencia-se, no entanto, como um confronto entre vozes que disputam papéis/lugares sociais e familiares. As análises revelam que as fronteiras, delimitadas pela alternância dos sujeitos falantes, entre perguntas e respostas dos terapeutas e seus pacientes, constituem um processo de interação de vozes sociais, em contínuos entrecruzamentos e reconfigurações. Revelam também que os terapeutas constroem hipóteses para a intervenção nos conflitos familiares por meio dos deslizamentos dos sentidos (re-significação) e que buscam, para a resolução desses conflitos, o deslocamento enunciativo das vozes dos pacientes de uma posição monológica (ainda que presencial) para posições dialógicas.This thesis investigates the discursive practices in systemic family therapy sessions. It focuses on the (re)construction of meanings in such therapeutic discourse, by focusing on what, within the therapeutic field, is known as re-signification and by attempting to consider critically the patient\'s request for help and the therapist\'s act of helping. It investigates also the subjects\' social/family places - including a certain representation by the therapist - when interacting at the therapy. Starting from the Bakhtinian notion of dialogism, which is revisited in the studies on enunciative heterogeneities by Authier-Revuz, the frontiers of otherness - evinced in the \"therapy session\" discourse gender - are observed, specifically in pieces of dialogues taken from three family therapy sessions held in teaching and research institutes (two of them autonomous institutions and a federal autarchy). Such discourse gender, which, in its surface might be understood as meeting aimed at therapeutic ends for discussing themes of human conflicts in relational situation, constitutes, however, a clash of voices that dispute family and social roles/places. The analyses reveal that the frontiers, circumscribed by the alternation of speaking subjects, between questions and answer of the therapists and their patients, consist of a process of social voices interaction, throughout continuous intercrossings and reconfigurations. The analyses demonstrate also that the therapists formulate hypotheses for the intervention in the family conflicts through the meaning slides (re-signification) and that they seek, for solving such conflicts, the enunciative displacing of the patients\' voices from a monological position (even though witnessed) to dialogical positions.

Approved for public release; distribution is unlimited.This thesis presents a formal analysis process and the results of applying that process to the MLS LAN: TCB-to- TCBE, Session Status, and TCBE-to-Session Server Protocols. The formal analysis process consists of several distinct stages: the creation of a detailed informal protocol description, analyzing that description to reveal assumptions and areas of interest not directly addressed in the protocol description, the transformation of that description and the related assumptions into a formal Strand Space representation, analyzing that representation to reveal assumptions and areas of interest, and concluding with an application of John Millen's automated Constraint Checker analysis tool to the Strand Space representations under an extremely limited set of conditions to prove certain protocol secrecy properties.

The background for this masters thesis is the threat of session hijacking in public wireless networks. A public wireless network in this context is a network such as Wireless Trondheim where users with WLAN enabled devices can connect for a small fee for a given period of time. These kind of networks relies on having a high degree of user friendliness to reach users with average knowledge in computers and wireless networks. There is always a struggle between user friendliness and security and the downside to the user friendliness in these kind of networks is poor security. Many of these networks only use the unique identifier (MAC address) of the network device to identify users and grant them access. A person with some technical knowledge about wireless networks and less then honest intentions may exploit this weak security barrier and impersonate the legitimate user by duplicating the MAC address. The practical part of this master thesis starts with the setup of a test bench with three computers, an attacker, a legitimate client and a passive monitor. A MAC spoofing attack was performed on the production network to prove that this kind of attack is easy to perform. The attack was first done with Backtrack which is a specialized penetration testing OS and the same type of attack was done in Windows to also prove that it does not require specialized tools. The attacker was able to gain access to the Internet without going through the web page for authentication. The thesis also proposes some countermeasures against this kind of attack. They are session ID, MAC sequence number tracking and monitoring physical properties such as received signal strength and RTS-CTS handshake round trip times. The thesis presents some thoughts on how they can be implemented in the wireless Trondheim network and what the major difficulties of each of them might be. The thesis also makes an evaluation of how well each of them fit with Wireless Trondheims requirements for countermeasures against the attacks done in this thesis.

In this thesis, a multi-functional vacuum lamination machine which laminated touch panel and liquid-crystal display (LCD) panel by optically clear adhesive (OCA) is been developed. The prototype machine is fabricated, tested and verified after concept design, mechanical design, visual alignment system design and hardware and software application. During the machine development, a novel lower chamber module of vacuum lamination is proposed that using linear stages of upper and lower position to visual align and vacuum laminate simultaneously. By applying the module, the process speed and the machine volume are enhanced and decreased, respectively. Meanwhile, the function of high speed atmospheric lamination for lamination of touch panel and OCA is also integrated and added in the this machine. In addition, this thesis designs a novel rotary mechanism which controls the lamination alignment by using linear driver and linkage mechanism. The lamination accuracy is enhanced successfully according to the mathematical models of the rotary mechanism. The results indicate that the lamination accuracy, repeatability, throughput and yield rate are greatly enhanced using the novel multi-functional lamination machine. Moreover, the cost is reduced clearly through evaluation, optimization and strict selection of the appropriate components. Therefore, this thesis can provide the promotion of related basic works in the aspect of vacuum laminating technology and future equipment exploitation on academia and industry.

Since the lifting of the municipal government, Kinmen turned to promote the tourism industry in order to enhance economic development. In 2016, the national army transferred the two islands (namely Dadan and Erdan) to Kinmen County government. The Kinmen County government considered to open the Dadan Island for sightseeing. The integration of Dadan tourism resources in terms of the status quo is able and possible to create a differentiated sightseeing attraction and attract tourists to visit the island. In order to do so, it is important to understand tourists' expectation and reflect these needs in the design of tourism service on the island so as to enhance the tourist satisfaction after the visit. In addition to the literature, the research suggests that the tourist attraction of Kinmen is the unique battlefield cultural history of Kinmen and the early military fortifications. This study starts from the perspective of tourists' needs, and utilizes the core of gamification to design questionnaire. The method of face-to-face questionnaire was adopted to explore tourists' expectations on the service content. The survey collected 277 valid questionnaires, and these questionnaires provided a vehicle for the empirical analysis via the use of descriptive statistics, analysis of variance, and regression. The results show that ： 1. Tourists possess different perspectives toward the service content in the pre-, during, and post-behaviors. 2. Activities proposed in the pre-, during, and post-visit have influences on the future visit intention.

This dissertation is focused on the nurses' image and nursing's image which are constantly changing because nurses play various roles and are in these differently perceived. The image is changing as the time goes and in each culture is perceived a bit differently. In developed countries is the image both nurses and nursing the same. In theoretical field I was focusing on the internal image of nurses and external image of nursing, I shortly described what image is, factors which influenced the image of nursing, variety of medical workers' uniforms, the actual image of nurse. I also mentioned the importancy of this profession, the relationship between the profession of nurse ond nursing. In one of the chapters I focused on the strategy of building of positive image. The research of this dissertation was focused on finding out of the nurses' image from the nurses' point of view and from the public's point of view and especially what concerns the nurse's reliable influence of patients through their appearence, about respecting the standard of working uniforms and about how the nurses perceive their colleague with piercing, tatoo, dreadlocks. I was also interested in the way nurses educate themselves and so strengthen the nursing's image. I was also finding out how public perceive a real nurse, whether are...

In mobile computing, it is unavoidable to receive multimedia stream in a session through heterogeneous network interfaces or heterogeneous devices for better communication quality and performance. Session migration aims to maintain the continuity of the ongoing multimedia stream among the network interfaces and the devices. However, current approaches for session migration have compatibility problems because they modify streaming servers, routers, proxies, applications, or protocols. In the thesis, we propose a novel mobility management approach by means of session splice to achieve session migration. The approach maintains the continuity of the ongoing multimedia stream among the network interfaces and the devices without any modification excepting the end host. Without compatibility problems in other approaches, our approach can cooperate with existing Internet infrastructures and legacy applications. Our mobility management approach is realized in Linux and the experimental results show that the approach can achieve session migration with a slight overhead.

Nursing develops and becomes a field with scientific base and well-educated employees. Thanks to that, nursing care is safer and of better quality. Nurses obtain prestige, importance and autonomy. The aim of this thesis is to map haw the nurses perceive their the features and skills and what is the view of patients of the same features and skills of nurses. The research was performed using the quantitative method in the form of a non-standardised questionnaire. The research was aimed at opinion of nurses and patients and so the first research set consisted of general nurses and the second set consisted of patients of hospital wards and ambulances. There were used two types of questionnaires ? one of them designed for general nurses and the other one for patients. The questionnaires contained identical questions so as we could perform a comparative analysis of answers from nurses and patients. The data analysis proved that general nurses assess their practical and communication skills better than the patients. It was also established that patients consider the communication skills of nurses to be the most important skill, while nurses stated for their practical skills to be the most important part of nursing care. When comparing the results, significant differences were established in answers of both of the groups. It concerned mainly the field of communication skills of nurses. The patients selected negative answers to questions whether nurses ask the patients for their opinions and whether the nurses know how to communicate with families of nurses. The negative findings confirmed that the communication field remains to be a problem in nursing and that more attention should be paid to it. It is significant to train the communication skills of nurses.

The usual definition of empathy that can be found in books is that is a charakter, condition and process. It is considered the basic precondition of effective nursing practice and a means for reaching goals of treatment. Communication is unrepeatable in nursing in particular. The qualitative method of data collection - a semi-directed interview - was chosen for the research investigation. The interviews were conducted with the research set of twelve nurses and twelve patients. Two goals of the diploma thesis were defined; the first one was to map out what nurses and patients think about manifestation of empathy in nursing. The other goal was to compare the opinions of nurses and patients and to describe the differences ascertained.
