Full textAbstract:
This thesis is about the construction and design of a new air bearing test-bed to verify the programmed ACS attitude control algorithm and to validate the ACS MATLAB/SimuLink¬ model of NPSAT1, the second small satellite currently under development at the Naval Postgraduate School Space Systems Academic Group. The software was already verified and validated using a comparable air bearing test-bed. But due to changes in hardware from commercial magnetic torque rods to custom, NPS-built, magnetic torque coils, the changes in the modulated software have to be verified again. Additionally, the use of flight hardware on the test-bed is expanded to also verify and validate the currently available flight hardware. NPSAT1 is a passive, gravity-gradient stabilized satellite. This thesis shows the necessary fundamental requirements on the satellite's mass properties, which has to be met to realize a gravity-gradient stabilized satellite, as well as the basics of pendulum theory, which is required to set up the test-bed on the air bearing for testing. This thesis describes the measurement of the earth's magnetic field taken in the SSAG laboratory and the resulting magnetic field vector field. Restrictions dictatd by the air bearing are followed by a chapter that summarizes and explains all requirements on the new test-bed design. A detailed description of the chosen design approach, layout and available test-bed configurations is given, as well as issues encountered and their solutions.The next step is to verify the ACS MATLAB/SimuLink¬ attitude control algorithm and to validate the MATLAB/SimuLink¬ model using the designed air bearing test-bed. Further, it is suggested to proceed the verification and validiation of NPSAT1's behavior in space by using the custom, NPS-built, Helmholtz coils. With the assistance of Helmholtz coils, custom magnetic field properties can be generated.Space Systems Academic Group

Full textAbstract:
Introduction There is a pressing clinical need to treat patients with acute coronary syndrome (ACS) timely and efficiently in order to improve their prognosis. Standard tools available in ED, while useful, do not comprehensively characterize ACS for either diagnosis or risk stratification. The role of CMR in ACS is emerging because it allows assessment of both myocardial composition and function. Newer CMR techniques such as: a) T2 W imaging for assessing myocardial oedema and area at risk B) pre contrast T1 mapping techniques for quantitative characterization of the tissue composition, are adding further utility for CMR in ACS. At present the clinical use of these techniques is still limited and further investigations are needed to assess their clinical applicability in ACS patients. Aims The aims of this thesis were several. Firstly we sought to establish a CMR protocol for imaging ACS patients on a 3T CMR scanner. In order to do so, we validated a novel T2 W technique for oedema imaging (T2 prep SSFP) at 3T. Second, we aimed to perform a detailed study of the time course of oedema in ACS patients in order to establish the appropriate imaging time for the assessment of area at risk. Third, by applying T2W acute oedema imaging, we sought to investigate the functional and pathological meaning of complicated remote plaques in patients with multivessel disease. Finally, we aimed to establish whether, in comparison to standard CMR techniques, novel precontrast Tl mapping allows better characterisation of the acutely injured myocardium and whether it can predict long-term functional recovery. Methods The research studies were all performed on a 3T Trio Siemens scanner. In the initial stage of the research, we validated the T2 W technique performing phantom work and scanning both volunteers and patients to assess the uniformity of signal intensity in the myocardium and to establish a threshold based method to post process the images. We then established a CMR protocol for ACS including oedema imaging, T1 mapping imaging, perfusion, functional and late gadolinium enhancement imaging. Patients with acute myocardial infarction (both ST elevation myocardial infarction (STEMI) and non STEMI) were scanned at 4 different time points after the acute event (3 scans within 2 weeks and one at 6 months). All STEMI patients underwent primary percutaneous coronary intervention (PCI) while the non-STEMI patients underwent coronary angiography and for PCI. Results We validated the T2prep SSFP technique at 3T, highlighting its limitations and establishing a threshold of mean ± 2SD to assess myocardial oedema. We found that the optimal imaging window to assess the maximal expression of myocardial oedema was within 1 week from the acute event in patients with ST elevation MI. Also, our results showed a reduction of LGE over time (from acute to chronic) in segments which also showed improvement in contractile function indicating that even segments with transmural LGE assessed in the early hours post event could be viable. By applying these techniques in acute patients with bystander disease undergoing percutaneous coronary intervention, we found that: l) T2W imaging can detect myocardial injury downstream from a vessel identified as "non culprit" 2) in 20% of NSTEMI patients, the angiographic assessment alone failed to identify the culprit vessel. Finally, we found that the diagnostic performance of acute pre-contrast Tl-mapping was at least as good as that ofT2W CMR for detecting myocardial injury. There was a significant relationship between the segmental damaged fraction assessed by either by LGE or T2W, and mean segmental Tl values and the likelihood of improvement of segmental function at 6 months decreased progressively as acute Tl values increased. Conclusions In summary, we defined a stable imaging window for the retrospective evaluation of area at risk and we also indicated that acutely detected LGE does not necessarily equate with irreversible injury and may severely underestimate salvaged myocardium. Furthermore, in NSTEMI patients with multivessel disease, by revealing acute myocardial damage in territories pertaining to vessels not treated acutely, we raised the issue of the need for better tools for the correct identification of the culprit vessel and to stratify patients rather than by angiographic assessment alone. Finally, we demonstrated how pre-contrast Tl mapping allows for assessment of the extent of myocardial damage and how Tl mapping might become an important complementary technique to LGE and T2W for the identification of reversible myocardial injury and the prediction of functional recovery in acute MI.

Full textAbstract:
This document describes the design, analysis of Orbit Maneuvers and Attitude Control for NanoSat class satellites, which uses an electro-magnetic force controller which was proposed by the Florida Space Institute (FSI). Orbit Maneuvering and the Attitude Control System (ACS) play a very important role for the success of this mission, as that can allow making the satellite go to the desired orbit as well do the sun pointing of the solar arrays with su¢ cient accuracy to achieve desired power levels. The primary mission would be to attain attitude stabilization using the torque from the coils. This is also used for pointing at the direction of the sun, for achieving desired power levels. The secondary mission would be to use the force of the magnetic field and utilize that for orbit maneuvering, and attain the desired trajectory. This thesis gives a presentation of this detailed analysis with a simulation using Matlab/Simulink. Mathematical model of the actuators and sensors used for this satellite are designed, so that the simulation gives us results very near to the actual ones.Health Monitoring is also one of the main issues addressed in this work. This simulation helps us in understanding the mission as well as the requirements very well, and helps us know all the shortcomings. The FUNSAT satellite is modeled as an example in Simulink together with a Kalman filter for attitude estimation based on all sensor measurements. The theory behind this, and extending the Kalman filter, is also presented.M.S.

Full textAbstract:
Introduction
The TR-24 is relatively new to the cyclotron market and its advantages over lower energy PET cyclotrons have not yet been fully realized. A new high current [18F] fluoride production target that takes advantage of the higher energy and current afforded by the TR-24 has been developed.
Material and Methods
The TR-24 cyclotron presents challenges of producing conventional PET isotopes even with its variable energy capability (18–25 MeV). Simultaneous irradiation of two targets that require different proton energies is possible only using beam energy degrader. Due to the relatively wide energy window, the degrader design is not trivial, especially for the high current operation. For example, reduction of beam energy from 24 to 18 MeV would require the use of an approximately 1.5 mm thick aluminum degrader. At 100 μA this degrader would have to be capable of dissipating 700 W of beam power, which would be challenging to achieve with no cooling or using a conventional helium cooling window. However, cooling water used as a beam energy degrader can dissipate several kilowatts of beam energy and provide additional cooling for target material and window foils. FIGURE 1 demonstrates the concept of the water cooled target window. A standard 18F- water target with a 2.5 mL fill volume and a 30 degree beam incident angle was modified to accept the new water window. A 1 mm thick region of circulating cooling water was inserted between the vacuum and the product foil.
The combined beam energy degradation caused by the vacuum foil (0.00012“ Havar), the cooling water (1 mm) and the target foil (0.00012“ Havar) was approximately 7 MeV for a 24 MeV incident proton energy.
The target was installed on a target selector mounted directly on the TR-24 cyclotron. No additional beam focusing or steering devices were used to defocus or correct beam shape. A small recirculation water system was setup to supply cooling water for the degrader. A mixed bed ion exchange column was installed on the return line to trap N-13 and radioactive metal ions that could possibly be etched from the Havar foils. The water in the degrader was continually circulated in a closed loop providing cooling to the vacuum and target foils. An 800mL/min water flow through the degrader was generated by a low pressure water pump.
Results
Several tests were performed with O-16 water to establish current – pressure curve and to determine “burn through” current (FIGURE 2).
Conclusion
Initial tests demonstrated that the new F-18 target with a 1 mm water degrader is capable of accepting power levels in excess of 3.6 kW, operating at 150 μA. More testing is under way, including testing with H218O to determine the F-18 production capacity of this target. We will look into adapting this concept to all ACSI PET targets, including the high current F-18 produc-tion target which can potentially reach an operational current of 200 μA.

Mestrado em Biomedicina MolecularAcute coronary syndrome consists in a state of clinical symptoms compatible with acute myocardial ischaemia that may result from various thrombotic coronary artery diseases: unstable angina, non–ST-segment elevation acute myocardial infarction and STsegment elevation myocardial infarction. This disease normally occurs due to atherosclerosis, through the rupture of an unstable atherosclerotic plaque or through superficial endothelial erosion. Eventually the activation of the coagulation cascade and platelet adhesion, activation and aggregation ends up leading to acute thrombosis. Risk stratification in patients with acute coronary syndrome is very important in the determination of the proper treatment strategy. Various clinical features are known to be associated with an increased risk of a worse outcome in the event of an acute coronary syndrome and are taken into account in various risk scores. The main aim of this work is the determination of clinical characteristics that are associated with a worse outcome in a group of patients with acute coronary syndrome admitted to the Cardiac Intensive Care Unit of Hospital Infante D. Pedro, in Centro Hospitalar do Baixo Vouga, in order to identify potential prognostic markers in these patients, and the assessment of the association of these markers with other clinical characteristics, in order to determine their influence in the physiology of patients with acute coronary syndrome. A prospective observational study was conducted in 980 patients with acute coronary syndrome admitted to the cardiac intensive care unit of Hospital Infante D. Pedro, in Centro Hospitalar do Baixo Vouga, between January 2008 and June 2012. Data collected was analysed using Student's T-test, One-way Anova, Kruskal-Wallis test, Pearson’s X2 test, Fisher's Exact test, Cox Proportional Hazards Model e Kaplan-Meyer estimate, and included general clinical information and information regarding cardiac risk factors, general blood test, serum cardiac markers, left ventricular ejection fraction, provided revascularization therapy and previous and posterior cardiac events The results obtained indicate that female gender, advanced age, anemia, low left ventricular ejection fraction, the presence of a previous event, hypertension, dyslipidemia and obesity are associated with a poorer prognosis in patients with acute coronary syndrome.
O síndrome coronário agudo consiste num estado de sintomas físicos compatíveis com isquemia miocárdica aguda, podendo resultar de várias doenças arteriais coronárias: angina instável, enfarte agudo do miocárdio sem elevação do segmento-ST e enfarte agudo do miocárdio com elevação do segmento-ST. Esta doença ocorre normalmente devido a aterosclerose, através da rutura de uma placa aterosclerótica instável ou através de erosão endotelial. Eventualmente a ativação da cascata de coagulação e a adesão, ativação e agregação de plaquetas levam a trombose aguda. A estratificação do risco em pacientes com síndrome coronário agudo é muito importante na determinação da estratégia terapêutica adequada. Várias características clínicas estão associadas com um risco aumentado de um prognóstico adverso aquando de um síndrome coronário agudo, sendo tidos em conta em várias tabelas de previsão de risco. O principal objetivo deste trabalho é a determinação de características clínicas associadas com pior um prognóstico num grupo de doentes com síndrome coronário agudo internados na unidade de cuidados intensivos cardíacos do Hospital Infante D. Pedro, no Centro Hospitalar do Baixo Vouga, de forma a identificar potenciais marcadores de prognóstico nestes doentes, e a determinação da sua associação com outras características clínicas, de forma a determinar a sua influência na fisiologia de doentes com síndrome coronário agudo. Levou-se a cabo um estudo prospetivo observacional em 980 doentes com síndrome coronário agudo internados na unidade de cuidados intensivos cardíacos do Hospital Infante D. Pedro, no Centro Hospitalar do Baixo Vouga, entre Janeiro de 2008 e Junho de 2012. A informação recolhida foi analisada usando Student's T-test, One-way Anova, Kruskal-Wallis test, Pearson’s X2 test, Fisher's Exact test, Cox Proportional Hazards Model e Kaplan-Meyer estimate, e incluiu informação clínica geral e informação sobre fatores de risco cardíacos, análise sanguínea geral, marcadores cardíacos séricos, fração de ejeção ventricular esquerda, terapia de revascularização e eventos cardíacos prévios e posteriores. Os resultados obtidos indicam que sexo feminino, idade avançada, baixa fração de ejeção ventricular esquerda, a presença de um evento prévio, hipertensão, dislipidémia e obesidade estão associados com um prognóstico adverso em pacientes com síndrome coronário agudo.

La memòria d'aquesta tesi doctoral s'estructura en un primer capítol on es descriuen els objectius de la tesi i l'organització del treball de recerca. Després, el Capítol 2: Anàlisis factorials de dades es destina a presentar les eines utilitzades en les anàlisis factorials de dades. S'introdueix una anàlisi de tipus general, l'anàlisi canònica per a la comparació de dos grups de variables, i llavors es generalitza per a mes de dos grups. Presentem les anàlisis de correspondències, simples i múltiples, com un cas particular de les anàlisis canòniques, però també des d'una perspectiva més clàssica. Es proporcionen tècniques de representació gràfica - representacions simètriques i Biplots - i el concepte d'inèrcia.En el Capítol 3: Models loglineals i models gràfics es desenvolupen els models loglineals i els models gràfics, el concepte d'independència condicional i el seu ús. Es desenvolupen, a continuació, la formulació dels models loglineals, les restriccions que els caracteritzen -suma zero o còrner zero- i les relacions de transició. Es realitza un estudi de la influència dels paràmetres en la generació de models, sobretot de la importància del termes de les interaccions sobre els termes independents i els efectes principals. En aquest capítol s'introdueix la deviància, com a raó de versemblança entre dos models, la seva expressió i relació amb l'estadístic χ2 i altres indicadors de divergència de models.
El Capítol 4: Estudi de les inèrcies en anàlisis de correspondències s'inicia amb la relació entre la inèrcia, el coeficient de contingència i la deviància. A continuació, s'estudien les descomposicions de la inèrcia com a contribucions dels individus, modalitats o variables i s'apliquen a l'estudi de matrius quadrades. En referència a les anàlisis de correspondències múltiples de la taula de Burt, es fa la descomposició de les inèrcies per blocs i s'estudia la problemàtica dels blocs diagonals. S'estudien metodologies de tractament i es fa una proposta de metodologia per al tractament de matrius quadrades no simètriques basada en una doble descomposició, per una part en l'anàlisi de la simetria-no simetria i per l'altra utilitzant la reconstitució factorial de la part simètrica, basada en un algorisme k-EM, on k és l'ordre de reconstitució. La reconstitució k-EM pot ser aplicada a les taules diagonals de Burt i ens porta a una anàlisi equivalent al Joint Correspondence Analysis.
En el Capítol 5: ACM respecte un model i ACM condicional es dedica a presentar les ACM sobre un model i l'ACM condicional, on una variable qualitativa externa juga el paper de partició. L'aportació es basa en realitzar l'estudi de la inèrcia i la seva descomposició, en dues parts lligades a la variable condicionadora externa: la inèrcia inter i la inèrcia intra. Es troba la formulació de la distribució i mitjançant aquesta, s'interpreta la importància o no del condicionament. Així doncs, usant l'ACM condicional i els models loglineals estudiem el comportament de la inèrcia en relació al model.
El Capítol 6: ACM multicondicional considera les problemàtiques que genera la implementació de l'ACM multicondicional, ja que no es pot generalitzar trivialment del cas simple. Mitjançant l'estudi de les inèrcies condicionals i els models loglineals es desenvolupa una proposta d'anàlisi multicondicional. Aquests resultats són comparats amb els que s'obtenen en un procés de modelització loglineal. S'aplica la proposta a un exemple en el Capítol 7.
El treball de recerca finalitza amb unes conclusions on es resumeixen les principals aportacions i s'indiquen quines podrien ser algunes línies de recerca futures en aquest camp i s'annexen les macros programades.
The research work memory is structured in a first chapter with the description of the objectives of the doctoral thesis and the research work organization. Then, the Chapter 2 Descriptive factorial analysis is exclusively dedicated to present the tools used in factorial analysis. A general analysis, the canonical analysis, to compare two groups of variables is introduced, and then it is generalized to more than two questions. We present correspondence analysis, simple and multiple, as a particular case of canonical analysis, but we present both methods also from a more classical point of view. We also introduce graphical techniques -symmetric displays and Biplots- and the inertia concept.
Chapter 3 Loglinear and graphical models introduces briefly loglinear models and graphical models, the conditional independence concept and its use. Next, we develop the loglinear model formula and the constraints that characterize the model -zero sum or zero corner treatment- and the transition relations. We make a study of the influence of the parameters over the model generation, especially about the significance of interaction terms over principal and independent terms. In this chapter we introduce the deviance, as a likelihood ratio between two models, its expression and its relation with the χ2 statistic and other model divergence indicators.
In Chapter 4 Study of the inertias in correspondence analysis we start with the relation among inertias, the contingence coefficient and deviance. Next, we study the inertia decomposition as the contribution of each individual, category or variable. It's applied to study the case of square matrices. With reference to the multiple correspondence analysis of the Burt table, we decompose inertia by blocks and we investigate the influence of the blocks of the diagonal. A summary of several treatment methodologies is done. We propose a new methodology to treat squared skew-symmetric matrices, based on a double decomposition, on the one hand, in the symmetry-skew-symmetry analysis and on the other using the factorial reconstitution of the symmetric part, based on a k-EM algorithm, where k is the reconstitution order. The k-EM reconstitution methodology can be applied to the diagonal tables of a Burt table, which leads a result equivalent to Joint Correspondence Analysis.
In Chapter 5 - MCA with respect to a model and conditional MCA- firstly we start presenting MCA with respect to a model. Secondly we discuss conditional MCA, where an external variable plays a partitioning role. The contribution is based on studying the inertia and its decomposition in two parts linked to the external conditioning variables, the inter and intra inertia. Next, we find their distribution function and, by means of this, we can test the significance of the conditioning variable. Therefore, using the conditional MCA and loglinear models introduced before, we study the inertia behaviour with relation to the model and with different relation levels between the variables.
The Chapter 6 -Multiconditional MCA- consideres problems generated by the implementation of multiple conditional analysis, since it is not possible to generalize this definition to the simple conditional case. By means of the study of conditional inertias and loglinear models, we develop our proposal for a multiconditional analysis. These results are compared with the results obtained in a loglinear modelling process. We apply our proposal to a data example in Chapter 7.
The dissertation ends with a chapter of conclusions which sums up our principal contributions and suggests some future research lines in this field of investigation and with the macros programmed and used.

Estudam-se problemas considerando interação estrutura-solo-estrutura ambientados nos programas SASSI 2000 e ACS SASSI. Inicialmente, interpreta-se o procedimento SASSI de solução do campo-livre em termos da aplicação direta de recursos de propagação de ondas de corpo elásticas. A seguir, no SASSI, variam-se parâmetros relevantes como: relações entre as freqüências fundamentais do terreno e da estrutura, e entre as freqüências fundamentais e massas das estruturas vizinhas, distância relativa eixo a eixo e enterramento relativo entre as estruturas.As conclusões são visualizadas através de funções de transferência em aceleração, fornecidas pelo próprio SASSI, bem como por uma abordagem alternativa: a capacitância viscoelástica dos sistemas, sugerida como um parâmetro sintético interessante para avaliação da influência da presença de outros sistemas na resposta do sistema principal, utilizada ao longo de toda a faixa de freqüência de interesse, e por pequenas faixas de 5 em 5 Hz.Trata-se de uma rápida e primeira verificação da necessidade de realizar uma análise considerando duas estruturas. Faz-se também uma avaliação da variação espacial do movimento do terreno implementada no ACS SASSI, versão 2.2. Verifica-se a influência dessa consideração na solução do campo-livre, quando utilizados os diferentes modelos de coerência disponíveis no programa. Submete-se uma série de orientações e sugestões aos usuários desse conjunto de programas.
Situations involving structure-soil-structure interaction using SASSI 2000 and ACS SASSI protocols are concerned. Initially, techniques of elastic plane waves propagation in solids are used to understand SASSI free-field solution algorithm. Then, in SASSI scenery, some relevant properties of the model are varied and their influence on the interaction is analyzed. These parameters include: soil-main structure fundamental frequency ratio and between adjacent structures, structures mass relation and relative distance and embedment, between the main and the satellite structure. The responses are visualized trough SASSI 2000 acceleration transfer functions obtained in the central node of the top of the main structure. It is also proposed a new way of response visualization: the structural mechanical viscoelastic compliance, defined as the system ability to catch mechanical energy form the ground excitation and to keep it under a viscoelastic deformation state. It is suggested as a preliminary analysis stage to evaluate the influence of the satellite system in the main system response. A preliminary study on ground motion spatial variation using the ACS SASSI, version 2.2, protocol is also presented. One compares the influence of this consideration in the free-field solution, when the incoherence models available in the protocol are used. A couple of guide learnings and suggestions are left to the reader.

Objetivo: O estudo procurou dar visibilidade para elementos presentes no cotidiano de trabalho do ACS, buscando compreender como organiza as práticas de cuidado; constrói suas relações com a equipe de saúde; reflete sobre sua atuação no contexto da Estratégia da Saúde da Família; e as principais dificuldades que encontra para a realização de seu trabalho. Método: Investigação de natureza cartográfica, feita por meio de observação participante em seis UBS da região metropolitana da cidade de São Paulo, com produção de diários de campo, com registros de cenas observadas nas reuniões de equipe, atividades de grupo, visitas domiciliares, andanças pelos territórios e outras atividades. Para a análise do material, foi utilizado o conceito de “planos de visibilidade”, qual seja, aquilo que vai se destacando ou que vai se tornando visível/dizível, a partir das conexões das cenas de “natureza” semelhante registradas nos diários. Resultados e discussão: A partir dos planos de visibilidade foi possível discutir questões referentes à convivência cotidiana do ACS com a recusa da população; à violência e narcotráfico no território; ao difícil manejo dos segredos da comunidade; e às múltiplas dimensões do complexo vínculo com a comunidade atendida devido ao seu duplo estatuto morador/trabalhador. Foi possível compreender também um processo de transformação em curso deste trabalhador, que tem se apresentado como um trabalhador multiuso nas UBS, ocupando a função em caráter provisório. Isso é diferente do perfil idealizado pela política, que tem como uma das características uma certa “militância” constitutiva da função. Além disto, destaca-se a relação do ACS com a racionalização das práticas de saúde, que tem como um dos elementos a burocratização e as metas de produção, o que aumenta sua sobrecarga, mas também suas estratégias para manejar os fluxos, exercendo sua autonomia no território. A relação com a equipe de saúde aponta para dominação e subalternidade do ACS, mas também para movimentos de resistência, inventividade e para o trabalho cooperativo. Conclusão: O estudo permitiu evidenciar um trabalhador de saúde em mutação, que reproduz práticas biomédicas e burocratizadas, o que pode desfigurar o seu papel enquanto elo da comunidade, mas que também consegue ser bastante criativo, (re)inventando permanentemente suas práticas, de modo muito mais complexo do que prescrito nas formulações originais da política de saúde, em função, entre outras coisas, da complexidade dos territórios em que atua.
Introduction: This study focus on the work process of the Community Health Agents (ACS), an strategic actor in Brazilian National Health System (SUS) due to its role as “mediator”; between the community and the Primary Care Unit Health (UBS). Objective: This study aims give visibility to elements in the daily work of ACS, trying to understand how he organizes his care practices; builds his relationship with the health team; reflects on their performance in the context of the Family Health Strategy; and the main difficulties encountered to carry out his work. Method: Cartographic method made by participant observation in six UBS of the metropolitan region of São Paulo city that provides the production of field diaries with records of scenes observed in team meetings, group activities, home visits, walking through the territories and other activities. For analysis the concept of “visibility plan”; was used, which means what is highlighting or becomes visible / speakable from the connections of the scenes of similar “nature”; as recorded in field diaries. Results and discussion: From the visibility plans was possible to discuss issues relating to acquaintanceship of ACS with the refusal of the population; to violence and drug trafficking in the territory; to the difficult management of the community’s secrets; and to the multiple dimensions of the complex relationship with the community due to his dual resident / worker status. It was possible to understand a process of transformation of this worker, which has been presented as a multipurpose worker at UBS, occupying the role on an interim manner. This is different from the profile idealized by the ACS policy, which has a certain “militancy”; as a constitutive characteristic of the function. In addition it highlights the connection of the ACS with the rationalization of health practices, that has as elements the bureaucratization and the setting of production targets, increasing his work overload, but also his strategies to handle the flows, exercising their autonomy in the territory. The relationship of ACS with the health team points to domination and subordination of ACS, but also to his resistance movements, inventiveness and cooperative work. Conclusion: This study has highlighted a health worker in mutation that reproduces biomedical and bureaucratic practices, which can disfigure his role as a community link, but can also be quite creative, permanently (re)inventing his practices, in a way much more complex than prescribed in the original formulation of health policy, due, among other things, the complexity of the territories in which he operates.

Full textAbstract:
Despite predictions of Internet shopping reaching 6.9 trillion dollars by the end of 2004, research is now suggesting many online consumers are still very reluctant to complete the online shopping process. A number of authors have attributed consumers' reluctance to purchase online to apparent barriers, however, such barriers have not been fully examined within a theoretical context. While most studies of consumers' decision to shop on the Internet have focussed on key shopping determinants, this thesis builds a conceptual model grounded in consumer behaviour theory. In particular, this thesis explores the application of the perceived risk theoretical framework, specifically looking at one dimension of perceived risk theory - performance risk and the influence it has on the phenomenon of Internet Abandoned Cart Syndrome (ACS).
To explore this phenomenon, a number of extrinsic cues are identified as playing a major role in the performance evaluation process of online purchases. The combination of these elements enabled the researcher to develop a conceptual model from which a series of propositions were drawn. To acquire pertinent data and investigate each proposition, this study used a combination of indirect and direct techniques, namely projective techniques in the form of a third-person vignette, a structured tick-box questionnaire and finally semi-structured interviews.
The results suggest that collectively the extrinsic cues of brand, reputation, design and price have an overall impact on the performance evaluation process just prior to an online purchase. Varying these cues either positively or negatively had a strong impact on performance evaluation.
The conclusion of this study suggests consumers are often unable to measure the full extent of risk-taking directly. In the majority of cases, consumers are guided by numerous factors, some intrinsic, others extrinsic. E-tailers with an established reputation, a well designed web site with known brands and a balanced pricing strategy reduce the perceived performance risks associated with purchasing online, thus reducing the occurrence of ACS.

O BNP tem sido apontado como ótimo marcador de disfunção ventricular esquerda na sala de emergência. O poder de complementar informação prognóstica aos pacientes com SCA ainda não está bem estabelecido. Analisar a contribuição do BNP no prognóstico a longo prazo de pacientes com SCASSST. A partir dos resultados obtidos, verificar a associação dos níveis séricos do BNP com o TIMI RISK escore e com a área de miocárdio sob risco isquêmico. Foram avaliados 46 pacientes consecutivos portadores de SCASSST, discriminados por troponina I positiva (valor >0,5ng/ml), admitidos no período de maio/2003 a janeiro/2004, e acompanhados por um período de seguimento de 48 meses. O estudo foi completado por 40 pacientes. A análise do BNP de admissão e após 96 horas foi realizada pelo teste não paramétrico de Wilcoxon com intervalo de confiança de 95%. Um valor de p<0,05 foi considerado significante. Utilizou-se a curva ROC para analisar a acurácia do BNP de 96 horas como preditor de morte, além de definir o ponto de corte. O teste do qui-quadrado de Pearson foi utilizado para comparar as frequências das características clínicas, eletrocardiográficas e bioquímicas. Para avaliar um possível fator de confusão entre o BNP de 96 horas, idade e desfecho, usou-se a análise de regressão logística. Houve uma elevação do BNP entre a admissão e 96 horas (mediana de 148 vs. 267 p=0,04). Ocorreram 13 óbitos no período de seguimento. Utilizando o valor de corte do BNP de 96 horas de 300pg/ml como preditor de morte, observou-se sensibilidade de 92,3%, especificidade de 77,8%, valor preditivo positivo de 66,7% e valor preditivo negativo de 95,5%. A área sob a curva ROC foi de 0,93. Diferenças significativas não foram observadas nas características clínicas, eletrocardiográficas e angiográficas entre sobreviventes e não sobreviventes. Observou-se nítida associação entre o BNP de 96 horas com a pontuação do TIMI RISK escore. Verificou-se também a relação entre o incremento do BNP, admissão e 96 horas, e a anatomia coronariana no grupo com extensa área do miocárdio sob risco isquêmico (p=0,021). A elevação do BNP após 96 horas da admissão está associada a uma população com maior área de miocárdio sob risco isquêmico. Os resultados Indicam que o maior incremento entre o BNP de admissão e após 96 horas está associado à maior gravidade e extensão de miocárdio sob risco isquêmico. Tal fato poderia explicar a relação entre BNP elevado com a pontuação do TIMI RISK escore. Análise do BNP obtido após 96 horas de evento isquêmico é uma importante ferramenta na estratificação de risco de morte a longo prazo na SCASSST.BNP has been considered an excellent marker of left ventricular dysfunction in the emergency room. However, its ability to provide prognostic information on patients with acute coronary syndrome has not been well established. To assess the contribution of BNP to predict the long-term prognosis of patients with non-ST segment elevation myocardial infarction (NSTEMI). In addition, to assess the association of BNP serum levels with TIMI risk score and with jeopardized myocardial area. The study comprised 46 consecutive patients with NSTEMI, discriminated by positive troponin I (>0.5ng/mL), admitted from May 2003 to January 2004, and followed up for 48 months. Forty patients completed the study. The BNP levels at admission and 96 hours after that were analyzed by using the non parametric Wilcoxon test with 95% confidence interval. A p value <0.05 was considered significant. The ROC curve was used to assess the accuracy of the 96-hour BNP as a predictor of death, in addition to defining the cutoff point. The Pearson chi-square test was used to compare the frequencies of clinical, electrocardiographic, and biochemical characteristics. Logistic regression analysis was used to assess a possible confounding factor between 96-hour BNP, age, and outcome. An elevation in BNP was observed between admission and 96 hours after that (median of 148 vs. 267, respectively; p=0.04). Thirteen patients died during follow-up. By using the 96-hour BNP cutoff point of 300pg/mL as a predictor of death, the following were observed: sensitivity of 92.3%, specificity of 77.8%, positive predictive value of 66.7%, and negative predictive value of 95.5%. The area under the ROC curve was 0.93. Significant differences were not observed in clinical, electrocardiographic, and angiographic characteristics between survivors and non-survivors. A clear association of 96-hour BNP with TIMI risk score was observed. A relation between BNP increase, both at admission and after 96 hours, and coronary anatomy was observed in the group with an extensive jeopardized myocardial area (p=0.021). The increase in BNP 96 hours after admission is associated with a larger jeopardized myocardial area. The results indicate that the greater increase in BNP 96 hours after admission is associated with greater severity and extension of the jeopardized myocardium. That fact could explain the relation between increased BNP and TIMI risk score. Assessing BNP 96 hours after an ischemic event is an important tool to stratify the long-term risk of death in NSTEMI.

Full textAbstract:
Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorEsta pesquisa busca compreender a construção do percurso identitário do Agente Comunitário de Saúde (ACS) a partir da história de vida. Os objetivos colocados neste estudo foram analisar as formas como se constituíram os princípios e valores que orientam as práticas de cuidado do ACS e de construir uma narrativa que contemplasse como as contingências e os acasos produziram os sentidos para o seu percurso identitário. Para isto, utilizou-se a metodologia qualitativa heterogênea através da abordagem da História de Vida e da Análise de Conteúdo. A primeira - História de Vida, segundo Becker (1994) é a expressão de uma forma de vida, de conhecer crenças, valores e desejos de uma população estudada dentro do contexto da vida destes sujeitos. Para tanto, foram realizadas entrevistas com seis ACS que atuam há pelo menos dois anos no município do Rio de Janeiro. As entrevistas foram gravadas e, parcialmente, transcritas após o aceite e a assinatura do termo de consentimento. Acredito que os agentes podem operar entre si diferentes modos de fazer, uma vez que afetam e sofrem afetamentos, atravessam e ao mesmo tempo são atravessados por diferentes micro redes que geram solidariedade ou individualismo, humanidade ou animosidade nas inter-relações. Neste contexto, o estudo conclui que ainda que a maioria dos entrevistados não escolhesse a carreira de ACS, houve uma disponibilidade para aprender o ofício e um compromisso com as atribuições definidas para o exercício profissional. Aliado a isso, constatou-se também, que a inserção na profissão foi uma forma de conseguir um emprego formal que garanta uma renda fixa mensal. Não há o desejo de permanecer por muito tempo nesta profissão pelo desgaste físico e emocional que é fortemente sentido já no primeiro ano de trabalho. Em relação à construção dos sentidos para o percurso identitário dos ACS, os depoimentos apresentam uma identificação com as ações de ajuda e solidariedade presentes na vida dos sujeitos. E, dentre os valores ou princípios que constituíram a formação de um caráter ou identidade pessoal, que são determinantes para a atuação no cuidado à saúde das pessoas, destacam-se a sensibilidade, a escuta, o afeto, o acolhimento, a ética, a amizade e alteridade. Na discussão sobre a necessidade deste profissional ser morador da área que vai atuar, observou-se, a partir das narrativas, que esta exigência pode facilitar a abordagem. Contudo, a qualidade do cuidado não está diretamente relacionada a este critério que pode gerar distanciamento e desconfiança dos outros moradores. Logo, estudos como este se justificam para que se possa reafirmar a importância de trabalhadores do SUS, em especial, o ACS. Estes representam hoje mais de 200 mil trabalhadores da saúde pública e se espera que sejam profissionais responsáveis por um cuidado em saúde que respeitem as diferenças entre as pessoas, que não sobreponham a doença ao sujeito e não minimizem o sofrimento em função do cumprimento de metas e produção de dados a serem planilhados. Lutem, acima de tudo, pela defesa de qualquer vida.

Full textAbstract:
Diseases of the heart have been the number one cause of death in the Native American population for decades and is an adverse health disparity for this population. Heart disease mortality rates are higher in Native Americans than in the U.S. population (American Heart Association, 2015; Veazie et al., 2014). The purpose of this Doctor of Nursing Practice (DNP) project is to describe the acute coronary syndrome (ACS) experience among Native American adults who reside in northern Arizona and diagnosed with an acute myocardial infarction .A qualitative dominant mixed methods design (QUAL→quan) was used to describe the ACS symptom experience among this population. Data was collected from a convenience sample of nine Native American men residing on the Navajo and Hopi reservations in northern Arizona diagnosed with an acute myocardial infarction. The qualitative portion of this study consisted of a semi-structured interview and the quantitative portion consisted of the completion of a demographic questionnaire and the McSweeney Acute and Prodromal Myocardial Infarction Symptom Survey. Qualitative description were used to analyze the data and develop codes, subcategories, categories and themes. Descriptive statistics were used to analyze the data from the demographic questionnaire and MAPMISS results. The findings in this study revealed the average age of the first heart attack for these participants was 58 years. The average time from symptom onset to hospital presentation was 7.4 hours. A common prodromal symptom was very tired/unusual fatigue. Common acute symptoms were chest pain, shortness of breath, gastrointestinal symptoms and diaphoresis. Neck/throat, generalized chest, and top of shoulders were most frequently reported areas of acute pain or discomfort. Influences to not seeking treatment included ignoring symptoms or thinking symptoms would go away. Influences to seeking treatment included worsening or non-resolution of symptoms. Accessing health care was difficult for almost all participants and contributed to treatment delay. Findings from this study gave new insight on ACS symptoms and the ACS experience of Native American men, reinforced current knowledge of the health disparities that exist in this population, and will assist in the development of culturally-sensitive, community-based education programs directed toward the Native American population.

Full textAbstract:
This thesis constitutes an assessment of a Quality Improvement (QI) programme delivered to healthcare professionals managing patients with non-ST elevation Acute Coronary Syndromes (ACS). This is a mixed methods evaluation of a QI programme encompassing a range of quantitative analyses and a qualitative semi-structured interview programme. Data from ACS registries demonstrate that management of non-ST elevation ACS is sub-optimal with respect to guideline recommendations. A range of interventions such as educational programmes, financial incentives and publication of performance have been implemented in healthcare showing evidence of improved standards of care. Whilst these results are encouraging, further research is needed to understand the factors that facilitate improvement and whether results achieved are sustained. The European Quality Improvement Programme for Acute Coronary Syndromes (EQUIP-ACS) project was a cluster-randomised QI programme for healthcare professionals delivered to 38 hospitals in five European countries. Data for 2,582 non-ST elevation ACS admissions were entered onto a web-based database over approximately 12 months. The primary outcome was a composite of eight guideline-recommended treatments for ACS compared before and after delivery of the QI intervention. Additional exploratory analyses have been performed to assess: the use of risk stratification methods and effect of patient risk, effect of patient and hospital characteristics, long term results of the QI intervention and a qualitative evaluation based on semi-structured interviews conducted with healthcare professionals. The EQUIP-ACS QI intervention led to increased use of ACS treatments. Improvement achieved was not consistent across all patients however and those with comorbidities received poorer management. Use of risk stratification was independently associated with improved management. Improvement was sustained at two of the centres one year after the programme, although a trend for decline over time was observed. Qualitative interviews revealed a range of factors that may influence delivery of QI and should be considered for future QI programmes.

Full textAbstract:
Background. AHA guidelines have been established to reduce Acute Coronary Syndrome (ACS)-related morbidity, mortality and recurrent events post-discharge. These recommendations emphasize the patient as an engaged member of the health care team in secondary prevention efforts. Patients with high levels of activation are more likely to perform activities that will promote their own health and are more likely to have their health care needs met. Despite evidence and strong expert consensus supporting patients as active collaborators in their own ACS care, the complexity and unexpected realities of self-managing one’s care at home are often underestimated. This study seeks to examine the correlates of patient activation at hospital discharge and then identifies activation trajectories in this same cohort in subsequent months. Lastly, this study examines the association between patient activation and health care utilization in the year subsequent to an ACS event.
Methods. This study incorporates three aims: Aim 1, identification of the correlates of low patient activation post-discharge; Aim 2, identification of patient activation trajectories among this same cohort in the months following hospitalization; and Aim 3, examination of the association between patient activation and health utilization, post-discharge.
Results. Fifty-nine percent of ACS patients identified as being at the lowest two activation stages at the time of hospital discharge. Perceived stress (pidentified post-discharge: low, stable (T1), high, sharp decline (T2), and sharp improvement (T3). The majority of patients (67%) identified as being in T1. Those patients of older age (OR: 2.22; CI 1.4- 3.5), identifying as Black in race (OR: 2.14: CI 1.1- 4.3), and reporting moderate/high perceived stress (OR: 2.54: CI 1.4- 4.5) had increased odds of being in the low, stable trajectory. The bivariate analysis indicated a significant association (P=0.008) between low patient activation and self-reported hospital readmissions in the months following discharge. In the final model, moderate to severe depression (OR: 1.60; CI 1.1- 2.3) was the strongest predictor of readmissions in the 12 months subsequent to discharge.
Conclusions: Patients reported low activation at hospital discharge after an ACS event indicated that these patients were not prepared to take an active role in their own care. Correlates of low activation at discharge include moderate to high perceived stress, depression, and low social support. Furthermore, in the months following hospital discharge, the majority of these patients followed either a low/stable or a sharp decline activation trajectory. Hence, these results suggest that over time patients feel less and less confident to take an active role in self-management. Lastly, we found that patient activation may impact healthcare utilization in the year subsequent to hospital discharge, although patient self-reported depression appears to be the strongest predictor of utilization in the subsequent year. Future research is needed to better understand the relationship(s) among patient activation, depression, and health care utilization.

[N,N??-bis-(mercaptoethyl)-1,5-diazacyclooctanato]NiII, Ni-1, is known to undergo metallation reactions with numerous metals. [N,N??-bis-(mercaptoethyl)-1,5-diazacycloheptanato]NiII, (bme-dach)Ni or Ni-1??, differs from Ni-1 by one less carbon in its diazacycle backbone ring producing subtle differences in N2S2Ni geometry. Metallation of Ni-1?? with PdCl2, Pd(NO3)2, and NiBr2 produced three structural forms: Ni2Pd basket, Ni4Pd2 C4-paddlewheel, and Ni3 slant chair. In attempts to provide a rationale for the heterogeneity in the active site of Acetyl coA Synthase, metal ion capture studies of Ni-1 in methanol found a qualitative ranking of metal ion preference: Zn2+ < Ni2+ < Cu+. Formation constants for metal ion capture of Ni-1?? in water were determined for Pb2+, Ni2+, Zn2+, Cu+, and Ag+. A quantitative estimate places copper some 15 orders of magnitude above nickel or zinc in binding affinity. Sulfur dioxide uptake by Ni-1?? is characterized by significant color change, improved adduct solubility, and reversible binding of two equivalents of SO2. These combined properties establish Ni-1?? as a suitable model for gas uptake at nickel thiolate sites and as a possibly useful chemical sensor for this poisonous gas. Comparisons of molecular structures, ν(SO) stretching frequencies, and thermal gravimetric analyses are made to reported adducts including the diazacyclooctane derivative, Ni-1·2SO2. Visual SO2 detection limits of Ni-1 and Ni-1?? are established at 25 ppm and 100 ppm, respectively. Structural studies of products resulting from reaction at the nucleophilic S-sites of (bme-dach)Ni and [(bme-dach)Zn]2 included acetyl chloride and sodium iodoacetate as electrophiles are shown. The acetyl group is a natural electrophile important to the citric acid cycle. Acetylation of (bme-dach)Ni produces a five coordinate, paramagnetic species. Iodoacetate is a cysteine modification agent known to inhibit enzymatic activity. The reaction of (bme-dach)Ni and sodium iodoacetate yields a blue, six coordinate nickel complex in a N2S2O2 donor environment. The bismercaptodiazacycloheptane ligand binds lead(II) forming an unprecedented structural form of N2S2M dimers, in which Pb2+ is largely bound to sulfur in a highly distorted trigonal geometry. Its unusual structure is described in comparison to other derivatives of the bme-daco ligand. The synthesis and structural characterization of square pyramidal (bme-dach)GaCl are also given and compared to the analogous (bme-daco)GaCl.

Full textAbstract:
Electrocardiography (ECG or EKG) is the process of recording the electrical activity of the heart over a period of time using electrodes placed on a patient’s body. These electrodes detect the tiny electrical changes on the skin that arise from the heart muscle depolarizing during each heartbeat. [1] It is necessary for the diagnosis and prompt initiation of therapy in patients with acute coronary syndromes (ACS) and is the most accurate means of diagnosing conduction disturbances and arrhythmias. [2]ECG is an irreplaceable diagnostic method in clinical practice. It offers great diagnostic value at minimal costs while being a relatively quick, painless and noninvasive process. The quality of the resulting graph is depending on the accurate placement of the electrodes on the patients' body and that the patient lies absolutely still to avoid any muscle contractions which may lead to distortions of the graph.The interpretation of ECGs is a highly complex topic which requires lots of training and experience. Although there has been plenty of research on the topic of automated interpretation and pattern recognition of ECGs by computer algorithms and neural networks, a reliable interpretation of complex ECGs cannot be guaranteed as of today. While the trend seems to favor automated ECG interpretation, a clear prediction when these technologies have saturated the market cannot be given. One reason for this, similar to autonomous vehicles, is the issue of where liability can be found when an incorrect diagnosis leads to harming of a patient. For the foreseeable future we will most likely rely on the skill and experience of humans to interpret ECGs.

En este trabajo investigamos y discutimos la dimensión educativa del trabajo de los agentes de la salud comunitaria, desde los ASC del municipio de Mari – PB. Realizamos un breve recorrido histórico buscando las circunstancias en que la categoría surgió en el escenario nacional y también en el ámbito local. Recorrimos las directrices y las leyes que guían a los profesionales, haciendo la identificación de lo que caracteriza como educadores en salud y observamos como las prácticas de los ASC responden a estas directrices. Se trata de una investigación cualitativa y de explotación, apoyada en el sesgo de la etnometodologia. Fueron utilizados como fuentes de datos: grupos enfocados, entrevistas semiestructuradas, recogida bibliográfica, documental y diarios para la documentación de las actividades de campo. Participaron de la entrevista todos los cincuenta y tres ASC activos, once de ellos participaron de los grupos focales y cinco de los demás en la escritura de los diarios. Para hacer el análisis de los datos, recurrimos a la hermenéutica dialéctica, como se sugiere MINAYO (2007). En el análisis tratamos de entender lo que realmente sucede en la relación entre educación y salud cuanto al trabajo del grupo en cuestión. La discusión teórica se basa en la concepción de práctica educativa de FREIRE (2001), como una forma de educación no formal (GOHN, 1999; WERTHEIN, 1985; TORRES, 1992). Recurrimos a la concepción de educación popular, cuyo contexto está unido orgánicamente al surgimiento del PASC. Concluimos que los ASC surgieron en el escenario nacional desde experiencias exitosas de sujetos de origen popular y de diferentes regiones y lugares del país, con enfoque en el enfrentamiento de las dificultades sociales, y en las acciones de interés colectivo. En 1991, el MS creó el PASC que absorbió a los agentes ya existentes y amplió la propuesta, con enfoque en la promoción de la salud. El ASC es caracterizado como educador en salud, sin embargo, en el área de la práctica profesional esta identidad no es reconocida ni valorada lo suficiente, cuanto al ASC de Mari, verificamos que históricamente la actuación de la categoría aprecia más el acompañamiento y el atendimiento individual, que las acciones de prevención de interés colectivo y luchas socialmente más amplias, lo que interfiere en las reivindicaciones/luchas de la propia categoría. Con todo, este cuadro no es irreversible, se puede, a largo plazo, ser cambiado delante del esfuerzo conjunto de la categoría, de los que comandan y de los usuarios del servicio.
Neste estudo investigamos e discutimos a dimensão educativa do trabalho dos Agentes Comunitários de Saúde, a partir dos ACS do município de Mari – PB. Realizamos um breve percurso histórico buscando as circunstâncias em que a categoria emergiu no cenário nacional e também no âmbito local. Percorremos as diretrizes e leis que orientam os profissionais identificando o que os caracterizam como educadores em saúde e observamos como as práticas dos ACS de Mari respondem a estas diretrizes. Trata-se de uma pesquisa qualitativa e exploratória, apoiada no viés da etnometodologia. Foram utilizadas como fontes de dados: grupos focais, entrevistas semiestruturadas, pesquisa bibliográfica e documental e diários de atividades de campo.

Para análise de dados recorremos à hermenêutica dialética, conforme sugerida por Minayo (2007). Na análise, buscamos compreender o que é teoricamente previsto para acontecer e o que realmente acontece na relação educação e saúde quanto ao trabalho do grupo em questão. A discussão teórica fundamenta-se na concepção de prática educativa de Freire (2001), como uma forma de educação não-formal (Gohn, 1999; Werthein, 1985; Torres,1992). Recorremos à concepção de educação popular, em cujo contexto o surgimento do PACS está organicamente ligado. Concluímos que os ACS surgiram no cenário nacional a partir de experiências exitosas de sujeitos de origem popular em diferentes lugares e regiões do país, com relevância no enfrentamento de dificuldades sociais, e nas ações de interesses coletivos. Em 1991, o MS criou o PACS que absorveu os agentes já existentes e ampliou a proposta, com o foco na promoção da saúde. O ACS é caracterizado como educador em saúde, todavia, no campo da prática profissional esta identidade não é suficientemente reconhecida e valorizada. Quanto ao ACS de Mari, verificamos que historicamente a atuação da categoria privilegia mais o acompanhamento e atendimento individual, do que as ações preventivas de interesse coletivo e lutas socialmente mais abrangentes, o que interfere nas reivindicações/lutas da própria categoria. Contudo, este quadro não é irreversível, podendo, a longo prazo, ser mudado mediante esforço conjunto da categoria, dos que a gerenciam e dos usuários do serviço.

Full textAbstract:
For the past decade the Australian Customs Service (ACS) has been regarded as an
organisation in decline. Customs' history has been sporadically influenced by
numerous reports that identify many instances of 'maladministration'. More recently,
instances, such as the 'Midford Paramount Affair', have brought media and public
notoriety to Customs followed by the establishment of the Review of the ACS in May
1993 (The Conroy Report). This, the latest and most comprehensive report
undertaken on the ACS, documented administrative malfunctions of a major kind.
Each report, using its own rationale has recommended more advanced levels of
information technology (IT) application.
To study these protracted administrative issues, the author has used, as the basis of
analysis, a dynamic contingent decision-paths schema as well as furthering the
theoretical constructs of organisational 'reliability' theory. The dynamic contingent
decision-paths schema is designed to provide a conceptual framework regarding
public (and private) sector situations of agency decline, evaluation, strategic response
and finally 'turnaround' policy and implementation. The ACS is now implementing a
comprehensive turnaround strategy, which includes new and novel information
technologies.
Organisational 'reliability' theory relates to organisations that are required to be
highly reliable in their daily work-related activities otherwise crises of some major
magnitude may occur. These organisations need to practice near perfect
organisational and decision-making performance, and tend to be highly technical,
relying increasingly in turn on information technology in managing their respective
systems or operations. Customs was an early innovator in using Electronic Data
Interchange and is now pursuing e-commerce, which in part is being outsourced, to
EDS, a multinational company.
The study initially reviews the recent history of the ACS - 'mapping' the nature of the
organisation's decline, raising relevant factors which the author argues may be seen
as successive 'crisis points', and lastly, addresses the strategic 'turnaround' policies of
the organisation.
The author believes the nadir for Customs has been reached and there are now
positive signs that the ACS has commenced its organisational 'turnaround'.
Organisational design matters including structural and cultural issues have been
addressed which has allowed Customs to forge new relationships with its clients, as
well as fostering 'new' management philosophies. These new philosophies and
relationships, together with participation with an industry lead advisory team and a
new internal management team, have provided the catalyst for change and recovery.
Political and industry pressure and their formal involvement in a recovery strategy
provide a high level of confidence for Customs' future and the strategic and
operational changes being implemented.

Full textAbstract:
Cette thèse présente la conception et la mise en œuvre d'un imageur CMOS pour être utilisé dans biocapteurs intégrés basés sur Résonance Plasmonique de Surface (SPR). Tout d'abord, les conditions optimales pour la résonance plasmon dans une interface compatible CMOS / post-CMOS sont obtenus par modélisation avec COMSOL. Deuxièmement, un imageur CMOS de Colonne Actif (CMOS-ACS) du 32x32 pixels est mis en œuvre sur une technologie CMOS 0,35 um. Dans une interface d'or-eau avec une excitation de prisme, on constate que pour les prismes avec des indices de réfraction de 1,55 et 1,46, le couplage optimal avec le plasmon est obtenu pour des films d'or d'une épaisseur de 50 et 45 nm, respectivement. Dans ces conditions, environ 99,19% et 99,99% de l'énergie de la lumière incidente est transférée à le surface plasmon pour les deux prismes respectivement, à condition que la lumière incidente, avec une longueur d'onde de 633 nm, arrive avec un angle d'incidence de 68,45° et 79,05° respectivement. Il est également obtenu qu'un changement de RIU 10-4 de l'indice de réfraction du milieu diélectrique, produit un changement de 0,01 ° dans l'angle de résonance de plasmons qui, dans un schéma de modulation d'intensité de lumière produit une variation de 0,08% dans la lumière réfléchie au photodétecteur. En ce qui concerne le imageur CMOS, une photodiode n-well/p-substrate est choisi comme l'élément de photodétection, en raison de sa faible capacité de jonction, ce qui conduit à un rendement élevé et le gain de conversion élevé comparativement à une photodiode n-diff/p-substrate. Des simulations sur ordinateur avec Cadence et Silvaco produit une capacité de jonction de 31 FF et 135 fF respectivement. Le pixel de l'imageur est basé sur une configuration à trois transistors (3T) et présente un facteur de remplissage de 61%. Le circuit de lecture utilise une technique de capteur de colonne actif (ACS) pour réduire le bruit à motif fixe (Fixed Pattern Noise ou FPN en anglais) liée au le Capteur à Pixels Actif (APS) traditionnelle. En outre, Non-Corrélés Echantillonnage Double (Non-Correlated Double Sampling ou NCDS en anglais) et Delta double échantillonnage (DDS) sont utilisés comme techniques de réduction du bruit. Un montage optique expérimental est utilisé pour caractériser les performances de l'imageur, et nous avons obtenu un gain en conversion de 7,3 uV/e-, une capacité de jonction de la photodiode de 22 fF, un bruit de lecture de 324,5 uV, ce qui équivaut à 45 électrons, et une gamme dynamique de 50,5 dB. Les avantages de l'ACS et NCDS-DDS sont observées dans le niveau faible de FPN du pixel et de la colonne, avec une valeur de 0,09% et 0,06% respectivement. Le travail présenté dans cette thèse est une première étape vers l'objectif de développer une plateforme entièrement intégrée SPR pour biocapteurs, incorporant source de lumière, l'interface SPR, canal microfluidique, les éléments d'optique et imageur CMOSThis dissertation presents the design and implementation of a CMOS imager for use in integrated biosensors based on Surface Plasmon Resonance. First, the optimal conditions for plasmon resonance in a CMOS/Post-CMOS compatible interface are obtained by COMSOL modelling. Second, a 32x32-pixel CMOS-Active Column Sensor (CMOS-ACS) is implemented on 0.35 um CMOS technology. In a gold-water interface with prism excitation, it is found that for prisms showing refractive indexes of 1.55 and 1.46, optimal plasmon coupling is obtained for gold films with thicknesses of 50 and 45 nm respectively. Under these conditions, approximately 99.19% and 99.99% of the incident light's energy is transferred to the surface plasmon for both prism respectively, provided that the incident light, with a wavelength of 633 nm, arrives with incidence angles of 68.45° and 79.05° respectively. It is also obtained that a change of 10-4 RIU in the refractive index of the dielectric medium, produces a change of 0.01° in the plasmon resonance angle, which under a light intensity modulation scheme produces a change of 0.08% in the reflected light's energy reaching the photodetector. Concerning the CMOS imager, a n-well/p-substrate photodiode is selected as the photosensing element, due to its low junction capacitance, which results in high efficiency and high conversion gain compared to the n-diff/p-substrate photodiode. Computer simulations with Cadence and Silvaco produced a junction capacitance of 31 fF and 135 fF respectively. The imager's pixel is based on a three-transistor (3T) configuration and shows a fill factor of 61%. The readout circuitry employs an Active Column Sensor (ACS) technique to reduce the Fixed Pattern Noise (FPN) associated with traditional Active Pixel Sensors (APS). Additionally, Non-Correlated Double Sampling (NCDS) and Delta Double Sampling (DDS) are used as noise reduction techniques. An experimental optical setup is used to characterize the performance of the imager, obtaining a conversion gain of 7.3 uV/e-, a photodiode junction capacitance of 21.9 fF, a read noise of 324.5 uV, equivalent to ~45 e- and a dynamic range of 50.5 dB. The benefits of ACS and NCDS-DDS are observed in the low pixel and column FPN of 0.09% and 0.06% respectively. The work presented in this thesis is a first step towards the goal of developing a fully integrated SPR-biosensing platform incorporating light source, SPR interface, microfluidic channel, optical elements and CMOS imager

Full textAbstract:
Building upon Joseph et al's (1997) psychosocial model, the current thesis presents a framework for understanding the development of symptoms PTSD in patients with acute coronary syndrome (ACS). This framework identified personality (measured as alexithymia), cardiac threat (subjective and objective), peritraumatic reactions (fear and dissociation), appraisals (measured as illness beliefs), perceived social support (qualitative, confidant and affective) and use of coping (problem-focused, emotion-focused and support seeking) which were tested for their ability to predict the development and maintenance of symptoms of PTSD. In addition, due to high levels of co-morbidity between PTSD and other psychopathologies, these psychosocial variables were tested for their ability to predict more general distress (i.e. anxiety and depression).This thesis used a longitudinal, repeated measures questionnaire design methodology with 97 first-time ACS patients, across three different time points (hospital, 4-6 weeks and 6 months post-event). Alexithymia was found to be the strongest and most consistent predictor of PTSD, anxiety and depression. Many of the psychosocial variables overlapped for predicting distress however peritruamtic fear was uniquely predictive of PTSD, while subjective threat and affective support uniquely predicted depression. Overall, the study provided some support for the current framework as a model for PTSD. An additional aim of the thesis was the development of a new cardiac specific measure of patient concerns and concurrent coping during post-event adjustment. Results indicated that participants' most reported concerns related to the results of their angiogram, discovering their cardiac symptoms and fear about further heart problems during hospitalisation. At discharge, patients reported concern about further heart problems, the effect of their condition upon their family, their future and returning to 'themselves'. The most frequently used strategy was emotion-focused (try and think positively) followed by problem-focused (ask health-care professionals). Use of coping strategies varied in accordance with the specific concern and generally decreased over time. The current results were discussed in relation to clinical practice and patient care.

Full textAbstract:
Herbig Ae/Be (HAeBe) stars are intermediate mass (2-10 solar mass) pre-main sequence stars with circumstellar disks. Observing planets within these young disks would greatly aid in understanding planet formation processes and timescales particularly around massive stars. So far, only one planet, HD 100546 b, has been confirmed to orbit a HAeBe star. With over 250 HAeBe stars known, and several observed to have disks with structures thought to be related to planet formation, it seems likely that there are as yet undiscovered planetary companions within the circumstellar disks of some of these young stars. Direct detection of a low-luminosity companion near a star requires high contrast imaging, often with the use of a coronagraph, and the subtraction of the central star's point spread function (PSF). Several processing algorithms have been developed in recent years to improve PSF subtraction and enhance the signal-to-noise of sources close to the star. However, many HAeBe stars were observed via direct imaging before these algorithms came out. We used the PSF subtraction program PynPoint to reprocess archival images of HAeBe stars from the Advanced Camera for Surveys on the Hubble Space Telescope to increase the likelihood of detecting a planet in their disks. We believe we have recovered the known planet around HD 100546 and possibly its candidate second companion. We also detect new candidate sources in the vicinities of HD 141569 and HD 163296. Further observations are needed to confirm the reality of these detections and also establish their association with the host stars.

Objetivo: As proposições do presente estudo do tipo transversal foram: avaliar o índice de respostas positivas sobre saúde bucal dadas em um inquérito validado contendo 18 questões fechadas, realizado com agentes comunitários de saúde (ACS) que atuam na zona urbana de Porto Velho, Ro e Verificar se os ACS exercem influência sobre os usuários de unidades de sua área de atuação. Métodos: No total, 656 sujeitos participaram do estudo. Para atender à primeira proposição, foram entrevistados 326 ACS. Para responder à segunda proposição, foram incluídos 167 usuários de unidades localizadas em áreas cobertas por ACS e 163 em áreas não cobertas. Foi aplicado o teste Mann-Whitney para verificar diferenças entre as amostras de ACS e usuários cobertos. O mesmo teste foi utilizado na comparação entre as duas amostras de usuários. Para identificar interferência do nível de escolaridade sobre o conhecimento dos usuários cobertos por ACS foi utilizado o teste Kruskal Wallis. O nível de significância adotado nos dois testes foi de 5%. Resultados: Em relação à primeira proposição, os conhecimentos sobre saúde bucal dos ACS apresentaram-se condizentes com os de outros estudos, quando a comparação foi feita previamente aos treinamentos específicos. Quanto à segunda proposição, os ACS não demonstraram exercer influência sobre os conhecimentos de usuários das unidades de saúde em que atuam. Conclusões: De forma geral, ficou patente a necessidade de cursos de capacitação específicos sobre o assunto ou a inserção desse tema nos programas de capacitação já existentes. Além disso, devem ser encontrados mecanismos para orientar os ACS a abordar a saúde bucal durante as visitas domiciliares.Objectives: The purposes of the present cross seccional study were: 1) to evaluate the index of correct answers about oral health given in a validated inquiry with 18 closed ended questions, applied to community health agents (CHA) that work in the urban area of Porto Velho, Brazil and 2) to verify the influence of CHA on the users of public health care services of its area of work. Methods: The final number was 656 individuals that participated in the study. To answer to the first purpose, 326 CHA were interviewed. To answer to the second purpose, 167 users of health care services located in areas with CHA actuation and 163 in areas where they do not act are included. The Mann-Whitney test was applied to verify differences between the samples of CHA and covered users. The same test was used in the comparison between the two samples of users. To identify interference of the level of education on the users knowledge of covered, the Kruskal Wallis test was used. The cut-off point for statistical significance was of 5%. Results: In relation to the first purpose, the knowledge about oral health of CHA came similar to other studies, when the comparison was made previously to specific trainings. In relation to the second purpose, CHA did not demonstrate to exercise influence on the knowledge of users of their health care service. Conclusion: It was clear that the CHA need of specific training courses about buccal health or the insert of that theme in the training programs already existent. Besides, it should be found mechanisms to guide ACS to deal the buccal health education during their home visits.

De nouveaux électrolytes à base de N-methyl sydnone (NMS) et de carbonates d'alkyle dissymétriques (ACS) ont été étudiés en vue de leur utilisation dans les accumulateurs à ion- lithium. Chacune de ces nouvelles molécules synthétisées présente une propriété intéressante pour cette application. En l'occurrence, la NMS possède une constante diélectrique particulièrement élevée, quant aux ACS, leur température de fusion est très basse, ce qui leur confère la propriétés de rester à l'état liquide sur un large domaine de température. L'étude des propriétés physico-chimiques de ces solvants et de leurs mélanges avec d'autres carbonates usuellement utilisés dans les batteries tels le carbonate d'éthylène (EC) et le carbonate de diméthyle (DMC) ont été déterminées. La constante diélectrique, la viscosité, la conductivité d'un sel de lithium (en particulier LiPF 6) et le produit de Walden ont été quelques uns des paramètres considérés. Les performances électrochimiques ont également fait l'objet de cette étude. La détermination du potentiel de réduction et du potentiel d'oxydation ont contribué à mettre en évidence le domaine d'électroactivité. Le comportement électrochimique d'une électrode de graphite (cote anodique de l'accumulateur) et d'une électrode d'oxyde de cobalt (cote cathodique) ont été étudiés. Les différentes capacités, le comportement en cyclage et le vieillissement ont été évalués au cours de cette étude.

Full textAbstract:
This study uses the ACS first-term general chemistry exam to determine if one curriculum approach is more effective in increasing student success than the other based on their performance on the ACS exam. Two chemistry curriculum approaches were evaluated in this study; the traditional curriculum (TC) and the Atoms First (AF) approach. The sample population was first-semester general chemistry students at Collin College in Frisco, TX. An independent sample t-test was used to determine if there were differences in overall performance between the two curriculum approaches on two different versions of the ACS exam. The results from this study show that AF approach may be a better alternative to the TC approach as they performed statistically significantly better on the 2005 exam version. Factor analysis was used to determine if there were differences between the two curriculum approaches by topic on the ACS exam. Eight different topics were chosen based on topics listed on the ACS Examinations Institute Website. The AF students performed better at a statistically significant level than the TC students on the topics of descriptive chemistry and periodicity, molecular structure, and stoichiometry. Item response theory was used to determine the chemistry content misconceptions held by the students taught under both curriculum approaches. It was determined that for both curriculum groups the same misconceptions as determined by the Zcrit values persisted.

Find full textAbstract:
Negli ultimi anni, a causa di una sempre maggior attenzione ai problemi ambientali, si sta cercando di ridurre il consumo di risorse energetiche tradizionali sfruttando quelle rinnovabili. Ciò ha determinato lo sviluppo di impianti di riscaldamento multi-generatore, nei quali a fianco dei classici generatori di calore, si trovano anche sistemi a energie rinnovabili. Elemento centrale per la massimizzazione dello sfruttamento delle fonti rinnovabili è l’ottimizzazione dell’interazione fra i diversi sistemi di controllo dei singoli componenti dell’impianto. Per ottenere ciò sono necessarie le simulazioni dinamiche.
In questo elaborato di tesi è stato svolto uno studio sul comportamento dinamico di un impianto di riscaldamento e di produzione di ACS con caldaia e pannelli solari termici attraverso librerie Simulink.
La tesi ha avuto come obiettivo l’ottimizzazione del modello agendo sulla regolazione dei vari componenti. L’impianto è stato costruito attraverso una serie di step successivi che hanno portato alla creazione di quello finale. Inizialmente si è dimensionato il solo impianto per il riscaldamento composto da caldaia a condensazione, valvole termostatiche, radiatori e pompa.
Successivamente si è ampliato il modello per analizzare la produzione combinata di ACS e riscaldamento.
Infine si è integrato l’accumulo con un pannello solare termico allo scopo di diminuire il carico della caldaia per la sola produzione di ACS, analizzando il comportamento del sistema al variare della taglia dell’accumulo.
Per ogni step sono state effettuate diverse simulazioni con lo scopo di ottimizzare le prestazioni dell’impianto.
L’ottimizzazione dei controlli presenti nel modello ha permesso di analizzare concretamente il corretto accoppiamento dei vari componenti dimostrando l’efficacia dell’utilizzo di un software dinamico. Dalle conclusioni, infatti, si evince che componenti altamente prestanti se installati in impianti non adeguati rendono il sistema poco performante.

Full textAbstract:
Les mécanismes transcriptionnels régulant la transcription des gènes du collagène de type I (COL1A1 et COL1A2), dans des situations physiologiques et pathologiques telle que la sclérodermie, ne sont pas totalement connus. Dans cette étude, nous avons déterminé les effets des molécules de chondroïtine-sulfate (ACS) et de leurs hydrolysats (ACSh) issus de cartilage de Sélacien, dans des fibroblastes dermiques humains normaux d’adultes (FNA) et sclérodermiques (FS) en culture. Ainsi, nous avons démontré pour la première fois que les ACS et les ACSh inhibent l’expression du collagène de type I au niveau protéique et au niveau des taux d’ARNm COL1A1 et COL1A2, dans des FNA et des FS. De plus, les ACS et les ACSh diminuent l’activité transcriptionnelle du gène COL1A1 par l’intermédiaire de la région promotrice -112/-61 pb dans les FNA et les FS. Cet effet met en jeu les facteurs trans hc-Krox, Sp1 et CBF, qui sont tous trois des activateurs transcriptionnels de ce gène, et dont l’expression et l’activité de liaison sont réduites sous l’effet des ACS et des ACSh. Par ailleurs, dans des FNA et des FS, l’expression protéique du TGF-β ainsi que les taux de son ARNm ne sont pas modulés sous l’effet des ACS et des ACSh. Nous avons démontré que ces molécules diminuent les taux des ARNm de TbetaRI, de TbetaRII et de Smad 7, tandis qu’au niveau protéique aucun effet n’est observé excepté pour TbetaRI. En outre, dans les FNA et les FS, les ACS et les ACSh ne modulent ni l’expression protéique de Smad 2/3, ni son activité de liaison au niveau de la sonde consensus SBE. Du point de vue catabolique, des expériences préliminaires ont démontré que les ACS dans les FNA et que les ACSh dans les FS, augmentent les taux d’ARNm de MMP-1 et de MMP-3. Ainsi, nos résultats ont permis de mettre en évidence que les ACS et les ACSh possèdent des propriétés anti-fibrotiques. Cette étude suscite donc des intérêts dans la mise en place de nouvelles stratégies thérapeutiques à visées anti-fibrotiquesDespite several investigations, the transcriptional mechanisms which regulate the expression of both type I collagen genes (COL1A1 and COL1A2) in either physiological or pathological situations, such as scleroderma, are not completely known. In this study, we determined the effects of both native ichtyan chondroitin sulfate (CS) and its derived hydrolytic fragments (CSf) on human normal (NF) and scleroderma (SF) fibroblasts. Here, we demonstrate for the first time that CS and CSf exert an inhibitory effect on type I collagen protein synthesis and decrease the corresponding mRNA steady-state levels of COL1A1 and COL1A2 in NF and SF. Moreover, CS and CSf repress COL1A1 gene transcription through a -112/-61 bp sequence in both NF and SF and involve the transcription factors hc-Krox, Sp1 and CBF, which are transactivating factors of this gene, and whose expression and DNA-binding activity is decreased by both CS and CSf. In addition, TGF-beta protein expression and its mRNA steady-state levels are not modulated by CS and CSf, in both NF and SF. We demonstrate that chondroitin sulfate molecules down-regulate TbetaRI, TbetaRII and Smad 7 mRNA steady-state levels but not their respective protein expression, except for TbetaRI. Likewise, CS and CSf have no effect neither on Smad 2/3 protein expression nor on their binding activity on the SBE probe. Concerning the catabolic pathway, preliminary experiments demonstrate that CS in NF and CSf in SF up-regulate MMP-1 and MMP-3 mRNA steady-state levels. As a conclusion, our findings highlight a possible new role for CS and CSf as anti-fibrotic molecules. Thus, this project would certainly allow to establish new strategies targeting the treatment of fibrotic diseases

Previous issue date: 2006A Educação Popular na saúde, como estratégia de intervenção, visa à modificação do status quo da lógica dos serviços de atenção básica, priorizando a criação de espaços coletivos no qual a valorização do diálogo e a troca dos saberes e reflexões entre técnicos e populares são acolhidos e incorporados como processo em construção de conhecimentos e práticas voltados à superação da lacuna cultural existente entre os serviços e a população. Nesse sentido, o agente comunitário de saúde (ACS) tem papel relevante de mediador entre o serviço, a comunidade e os diferentes saberes. Estimula a autonomia e compartilha responsabilidades na busca do fortalecimento dos direitos à cidadania e do papel social do coletivo. Sensibiliza e desperta a população para a conquista e reivindicação de novas formas de interação com o meio e para o exercício de controle da própria vida. Considerando o papel do ACS no processo de resignificação das práticas de saúde junto à comunidade, torna-se relevante o estudo sobre o discurso e prática desse ator no processo de transformação da situação de saúde da comunidade, por meio de ações de Educação Popular em saúde. O Distrito Sanitário III (DS III) foi o pioneiro a desenvolver os projetos de Educação Popular em Saúde, direcionados para capacitação dos ACS. Utilizando metodologia qualitativa este trabalho trata-se de uma pesquisa exploratória, com o objetivo de analisar o papel do ACS, enquanto educador popular em saúde, para a transformação da situação de saúde da comunidade, no DS III, da cidade do Recife; levando em consideração as expectativas, desejos, motivações, dificuldades e desafios dentro da realidade vivenciada por eles neste trabalho. Foi observada a satisfação pessoal de todos ACS entrevistados que passaram por esta capacitação. Apesar de algumas dificuldades enfrentadas nesse processo de trabalho, relataram o fortalecimento de suas ações e valorização pessoal através da resignificação dos seus papeis perante a comunidade e equipe de trabalho. Hoje são reconhecidos e se reconhecem como Educadores, à medida que realiza sua prática compromissada com a comunidade que pertence e atua, para a transformação da realidade local, e conquista de relações mais humanas e igualitárias dentro e fora dos serviços de saúde

Full textAbstract:
Background: The American College of Surgeons guidelines suggest the use of intact gloves, double gloving, hands-free zone technique to pass sharp instruments, and blunt tip suture needles to protect patients, as well as the surgical team. This study estimates the extent to which these guidelines are followed in a large academic health system. Methods: Over a two-month period in the spring of 2010, 320 general surgical attendings, subspecialty surgical attendings, and surgical resident physicians practicing at a large academic health system, were approached during or after surgical conferences to participate in a cross-sectional study. Nearly 1/3rd completed an anonymous and voluntary self-administered survey. The survey included questions regarding knowledge of each technique, beliefs about effectiveness of each technique, and adherence to the guidelines. Responses were compared by surgeon rank. Results: Awareness of ACS recommendation guidelines was high among surgical attendings (68%) and residents (60%). While 60% of residents adhered to these recommendations, only 43% of attendings adhered. Both attendings (65%) and residents (64%) had similar negative perception toward double gloving in terms of tactile sensation and hand free zone hindrance during procedural operations during cases. Forty percent of residents and attendings agreed on unhindered concentration to hand free zone technique. Blunt tip suture needle use had low awareness and usage regardless of surgeon rank (~40%). Conclusion: Increased promotion of the ACS guidelines is warranted. Continuing medical education for surgical attendings may promote more widespread adoption of techniques to promote safety.

Full textAbstract:
ANTECEDENTS: Les infeccions urinàries són la causa més freqüent d'ingrés hospitalari per bacterièmia adquirida a la comunitat i fins a una quarta part poden presentar sèpsia greu a l'ingrés, una condició que s'ha associat a un pitjor pronòstic sobretot si l'antibiòtic inicial no és adequat. L'elecció de l'antibiòtic empíric adequat, actualment s'ha vist influenciat per dos fets: a) l'increment d'actuacions mèdiques dispensades en règim ambulatori, que ha donat lloc a un nou grup d' infeccions, "associades a cures sanitàries" (ACS) i b) l' increment de resistències entre les enterobacteries, moltes d'elles uropatògenes. HIPÒTESI: Dins de les infeccions adquirides a la comunitat, la infecció de tracte urinari bacterièmica (ITUB)-ACS està causada més freqüentment per microorganismes diferents a E.coli i/o multiresistents, fet que dóna lloc a una major inadequació de l'antibiòtic empíric i a una pitjor evolució dels pacients en relació amb la ITUB comunitària (ITUB-CO). Els pacients amb microorganismes multiresistents i/o ITUB-ACS presenten més sèpsia greu (SS) a l'ingrés i més mortalitat que els pacients amb microorganismes sensibles i/o ITUB-CO. OBJECTIU GENERAL: Conèixer les diferències clíniques, microbiològiques i de mortalitat entre les ITUB-ACS, les ITUB-CO i les ITUB d'adquisició hospitalària (ITUB-H). I determinar els factors associats a sèpsia greu a l'ingrés i a mortalitat als 30 dies. METODOLOGIA: Cohort prospectiva multicèntrica dels pacients ingressats amb ITUB durant octubre 2010 fins juny 2011 en 8 hospitals universitaris d'Espanya. La informació es recull mitjançant un protocol estandaritzat. Per detectar els factors associats a SS a l'ingrés i a mortalitat als 30 dies s'aplica una anàlisi de regressió logística. RESULTATS: Respecte als pacients amb ITUB-CO, els pacients amb ITUB-ACS van ser, amb més freqüència, homes (60% vs 31%, p<0,001) amb comorbilitat severa, McCabe II-III, (48% vs 14%, p<0,001) i van tenir més aïllaments d’Enterobacteriaceae-BLEE
(13% vs 5%, p<0,001). La teràpia inadequada i la mortalitat també van ser més elevades (21% vs 13%,p<0,02 i 11,4% vs 3,9%, p=0,001). En comparació amb les ITUB-H, l’aïllament de Pseudomonas aeruginosa i la mortalitat van ser menors (4% vs 16%, p<0,001 i 11,4% vs 20,4%, p= 0,01). La SS es va associar a comorbilitat severa (OR 1,90; IC95% 1,23-2,92), història d’uropatia obstructiva (OR 1,56; IC95% 1,03-2,34) i ser portador de sonda urinària (OR 3,01; IC95% 1,50-6,03). Encara que donada l’existència d’interacció, ser portador de sonda urinària només va ser factor de risc per SS en pacients amb comorbilitat no severa (McCabe I). La mortalitat als 30 dies en la cohort es va associar a l’edat (OR 1,04; IC95% 1,01-1,07), McCabe II/III (OR 3,2; IC95% 1,8-5,5), Pitt score ≥ 2 (OR 3,2; IC95% 1,8-5,5) i tenir una ITUB-H (OR 3,4; IC95% 1,2-9,0). CONCLUSIONS: la ITUB-ACS és una infecció diferent de les ITUB comunitària o adquirida a l’hospital, amb una epidemiologia, microbiologia i evolució pròpies. La presència de SS i la mortalitat s’associen sobretot a factors depenents de l’hoste sense cap influència del tipus de microorganisme causant ni del seu perfil de resistència.Nowadays, choosing an empirical antibiotic at the initial evaluation of patients with a bacteraemic urinary tract infection (BUTI) proceeding from the community is being hindered by the increasing rates of bacterial resistance, specially Enterobacteriaceae, and for changes in healthcare delivery. This latter determines a group of patients with a community-onset infection, but with resistant bacterial patterns more similar to hospital-acquired infections, group which has been named as healthcare associated (HCA) infections. Recent studies have identified BUTI as the most frequent cause of bacteraemia admitted in hospitals from the community. Taking into account that inadequate empirical antibiotic therapy has been associated with higher mortality rates and the scarcity of literature regarding BUTI this research aimed to analyse clinical characteristics, outcomes and risk factors associated with severe sepsis and mortality in a prospective cohort of 665 BUTI episodes requiring hospitalisation or already hospitalised collected in 8 tertiary-care hospitals in Spain. Patients were followed up until 30 days after the episode. Main results were that patients with HCA-BUTI in comparison to community-BUTI (CO-BUTI) were predominantly male with highest debilitating comorbidity. Differences that were not found when compared with hospital-acquired-BUTI (HA-BUTI). Structural or functional urinary tract abnormalities and history of urinary obstruction or recurrent infection were also more frequent in HCA-BUTI. E. coli was the predominant bacteria in all groups with higher rates of resistance to rd fluoroquinolones, amoxicillin-clavulanate and 3 generation cephalosporin in HCA- BUTI and HA-BUTI. Pseudomonas aeruginosa and other Enterobacteriaceae were especially isolated in HA-BUTI episodes. Inappropriate empirical therapy was significantly more frequent in HCA-BUTI compared with CO-BUTI episodes. Severe sepsis at presentation in BUTI was associated with having a fatal underlying condition, previous history of urinary tract obstruction or the presence of an indwelling urethral catheter, although the latter only in patients without a fatal underlying condition. Not the causative microorganisms or antimicrobial resistance patterns had an impact on the presence of severe sepsis. Mortality in HCA-BUTI was three times higher than CO-BUTI, however the highest mortality rate affected the HA-BUTI group. 30-day mortality was associated with age, debilitating comorbidity, clinical severity and having a hospital-acquired episode. Neither microorganism resistant profile nor inappropriate empirical therapy was associated with mortality.

The proposed modeling system for assessing undergraduate degree courses, according to the parameters required by ENADE emerges from the need of the IES adjust its methodology and assessment procedures to the terms set by the exam. The proposed solution does not address a specific undergraduate course and may be applied for any knowledge area. The use of software agents is justified on the grounds of a classical computer application not being able to adapt to the reality of each student, delivering the second behavioral questions identified during the evaluation process.The statistics generated from this reasoning will serve both for students and for teachers in order to reevaluate the teaching and learning process. The modeling was performed according to the UML 2.0 TROPOS methodology was used for the modeling of agents and their implementation was done in JADE.
A proposta de modelagem de sistema de avaliação dos cursos superiores de graduação, segundo os parâmetros exigidos pelo ENADE, emerge da necessidade das IES adequarem sua metodologia e procedimentos de avaliação aos moldes estabelecidos pelo exame. A solução proposta não se dirige a um curso específico de graduação, podendo ser utilizada para qualquer área do conhecimento. O uso de agentes de software em seu desenvolvimento justifica-se em razão de uma aplicação computacional clássica não ser capaz de adaptar-se à realidade de cada aluno, entregando quesitos segundo o comportamento identificado durante o processo de avaliação. As estatísticas geradas a partir deste raciocínio servirão tanto para os alunos como para os docentes no sentido de reavaliar o processo de ensino aprendizagem. A modelagem foi efetuada segundo a UML 2.0, foi utilizada a metodologia TROPOS para a modelagem dos agentes e sua implementação foi realizada no JADE.

Full textAbstract:
Bakgrund: I begreppet AKS ingår hjärtinfarkt och instabil angina. Hjärtinfarkt drabbar cirka 25 300 personer i Sverige årligen och för att förhindra återinsjuknande följer ett omfattande sekundärpreventivt arbete med start redan på sjukhuset. Sekundärpreventionen bygger på egenvård där information är en viktig komponent. Informationen berör många områden och syftar till att ge patienten förståelse och medverka till en förändrad livsstil. Cirka en tredjedel av patienterna som haft hjärtinfarkt når de nationella målvärdena för sekundärpreventionen. Tidigare forskning har visat att patienter upplever informationen under vårdtiden som otillfredsställande. Patienter som har dålig förståelse för sin hjärtsjukdom deltar också mer sällan i sekundärpreventiva behandlingsprogram. Personcentrerad vård har positiva effekter på följsamhet till behandling och behandlingens resultat. Individens förmåga att förändra sin situation påverkas också av graden av hälsolitteracitet och empowerment. Syfte: Syftet var att beskriva behovet av information för att erhålla förståelse hos patienter med akut koronart syndrom från insjuknande till hjärtrehabilitering. Metod: Mixad litteraturöversikt med systematisk sökstrategi. Totalt 16 artiklar inkluderades, lika många kvantitativa som kvalitativa artiklar. En integrativ analys av materialet utfördes i syfte att sätta artiklarnas resultat i relation till varandra samt identifiera likheter och skillnader. Därefter identifierades kategorier som beskriver de granskade artiklarnas resultat. Resultat: I resultatet framkom tre huvudkategorier; all information är viktig, information genom hela vårdförloppet efterfrågas och anpassad information är meningsfull. Patienter ansåg inte att någon information var oviktig och information efterfrågades vid insjuknande även om den första tiden vid AKS präglades av chock. Även efter hjärtrehabilitering och två år efter AKS fanns behov av information om bland annat farmakologisk behandling, vilket också var det informationsområde som nämndes i flest studier. En återkommande fråga hos patienterna var varför AKS drabbat just dem. De önskade kongruens i information från olika källor och hade svårt att applicera standardiserad information på sin egna situation. De efterfrågade individuellt anpassad information som gavs när de själva var redo för det och som inkluderade anhöriga. Slutsats: Behovet av information är omfattande och patienter ansåg inte att någon information var oviktig. Även information i ett skede som präglas av chock är efterfrågad och betydelsefull. Individuell information underlättar förståelse för relevans av livsstilsförändringar och möjliggör delaktighet. Informationsbehovet varierade över tid och kvarstod till viss del efter två år.Background: The term ACS includes myocardial infarction and unstable angina. Myocardial infarction afflicts approximately 25 300 individuals in Sweden annually and to prevent recurrent ACS an extensive secondary prevention effort starts while patients are still in hospital. Secondary prevention builds upon self care where information is an important component. The information concerns a variety of areas and aims to increase the patient’s understanding and participation in lifestyle change. Just about one third of patients suffering from myocardial infarction reaches the secondary prevention goals. Previous research has shown that patients find the information received during the hospital stay unsatisfactory. Patients with a low understanding more rarely participates in secondary prevention programmes. Person centered care positively affects treatment compliance and results. The individual’s ability to change their situation is also affected by the amount of health literacy and empowerment. Aim: The aim was to describe the need of information to obtain understanding in patients with acute coronary syndrome from sickening to cardiac rehabilitation. Method: Mixed literature review with a systematic search strategy. In total, 16 articles were included of which half was quantitative and half was qualitative. An integrated analysis of the material was conducted in purpose of relating the results to each other and to identify similarities and differences. Thereafter categories that describe the reviewed literature were identified. Results: In the result three main categories emerged; all information is valuable, information is requested throughout the entire care chain and adapted information is meaningful. Patients did not find any information unimportant and the information was requested at the initial phase of getting ill although the phase was characterized by shock. Even after cardiac rehabilitation and two years after ACS a need of information about pharmacological treatment existed among others, which was the information area requested in most studies. A reappearing question among patients was why the ACS had happened to them. They wished for congruence in information from different sources and found it hard to apply standardized information to their own situation. They requested individually adapted information delivered at a time when they were ready for it, that also included their family. Conclusion: The need of information is extensive and patients did not consider any information unimportant. Even information in a state characterized by shock is requested and valuable. Individual information facilitates understanding of the relevance of lifestyle changes and enables participation. The information need varied over time and remained after two years to some extent.
