Desenvolvimento de uma plataforma wireless para prescrição médica e verificação de sinais vitais baseado em PDA

Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico, Programa de Pós-Graduação em Engenharia Elétrica, Florianópolis, 2009O registro de dados dos pacientes internados em estabelecimentos de saúde envolve rotinas que objetivam descrever seu estado atual de saúde. Apesar da crescente informatização, algumas destas tarefas, como a prescrição médica e verificação dos sinais vitais, ainda são executadas manualmente, o que aumenta o tempo de atendimento e ocorrência de erros. Assim, a proposta deste trabalho é desenvolver um protótipo de sistema para visualização e prescrição de medicamentos, bem como possibilitar a visualização e transcrição das informações referentes a verificação de sinais vitais diretamente no Prontuário Eletrônico de Paciente, reduzindo um dos principais fatores de risco encontrados no meio hospitalar: a má interpretação das informações contidas nestes documentos. Este sistema foi baseado em dispositivos móveis do tipo PDA (Personal Digital Assistent) com acesso à web e utiliza como meio de comunicação a wireless, possibilitando desta forma, o acompanhamento do paciente em seu leito pela equipe enfermagem e médica. Para avaliar o protótipo desenvolvido, foram utilizados questionários aplicados aos profissionais atuantes no Hospital da Universidade Federal de Santa Catarina, com a finalidade de verificar aspectos subjetivos de usabilidade (Satisfação) e observação do tempo gasto nas atividades diárias de verificação dos sinais vitais no processo tradicional. Os resultados mostraram que o grau de satisfação médio entre os participantes foi de 78,85 pontos, em escala de 0-100. Quanto ao tempo gasto nas atividades de verificação dos sinais vitais, o sistema apresentou ganho de 97,6%, em média, o que se atribui à redução das etapas a serem realizadas, quando comparado ao processo tradicional

Desenvolvimento de um Sistema de Raciocínio Baseado em Casos na Identificação de Transtornos Mentais

Este artigo descreve o desenvolvimento do Sistema Heuristia. O Heuristia é uma ferramenta disponível via web com o objetivo de auxiliar no diagnóstico de transtornos mentais aplicado na área de psiquiatria, utilizandose para tal da técnica de Raciocínio Baseado em Casos. A técnica de raciocínio baseado em casos propõe a solução de novos problemas adaptando soluções que foram utilizadas em problemas anteriores. A similaridade entre os casos baseia-se na comparação entre casos cadastrados por um especialista da área e um “caso alvo” ou “novo caso”, a ser comparado. Além disso, o sistema conta com o HeuristiaHelp que contém informações sobre definições de termos e procedimentos da psiquiatria

Engenharia de Software - PERSISTE: Framework para persistência de dados isolada à regra de negócios

A crescente necessidade de desenvolver softwares em um menor espaço de tempo, faz com que surjam novas ferramentas e frameworks de apoio aos desenvolvedores. Umas das tarefas importantes para o desenvolvimento de sistemas é o desenvolvimento da camada de persistênciados dados. Com relação a esta lacuna a proposta deste trabalho é desenvolver um framework que agilize o desenvolvimento da camada de persistência de objetos em um banco de dados relacional utilizando Java e facilite aos programadores e alunos dos cursos de informática, na compreensão dos conceitos sobre Mapeamento Objeto Relacional. Com o intuito de avaliar a usabilidade do Persiste, foi elaborado um questionário e a apuração dos resultados mostra que 90,48% dos entrevistados pretendem utilizar oframework novamente, e 80,96% acham extremamente simples a sua utilização

Carbon nanotubes

International audienceCarbon nanotubes (CNT s) are remarkable objects that once looked set to revolutionize the technological landscape in the near future. Since the 1990s and for twenty years thereafter, it was repeatedly claimed that tomorrow's society would be shaped by nanotube applications, just as silicon-based technologies dominate society today. Space elevators tethered by the strongest of cables, hydrogen-powered vehicles, artificial muscles: these were just a few of the technological marvels that we were told would be made possible by the science of carbon nanotubes. Of course, this prediction is still some way from becoming reality; most often the possibilities and potential have been evaluated, but actual technological development is facing the unforgiving rule that drives the transfer of a new material or a new device to market: profitability. New materials, even more so for nanomaterials, no matter how wonderful they are, have to be cheap to produce, constant in quality, easy to handle, and nontoxic. Those are the conditions for an industry to accept a change in its production lines to make them nanocompatible. Consider the example of fullerenes – molecules closely related to nanotubes. The anticipation that surrounded these molecules, first reported in 1985, resulted in the bestowment of a Nobel Prize for their discovery in 1996. However, two decades later, very few fullerene applications have reached the market, suggesting that similarly enthusiastic predictions about nanotubes should be approached with caution, and so should it be with graphene, another member of the carbon nanoform family which joined the game in 2004, again acknowledged by a Nobel Prize in 2010. There is no denying, however, that the expectations surrounding carbon nanotubes are still high, because of specificities that make them special compared to fullerenes and graphene: their easiness of production, their dual molecule/nano-object nature, their unique aspect ratio, their robustness, the ability of their electronic structure to be given a gap, and their wide typology etc. Therefore, carbon nanotubes may provide the building blocks for further technological progress, enhancing our standard of living. In this chapter, we first describe the structures, syntheses, growth mechanisms, and properties of carbon nanotubes. Then we introduce nanotube-based materials, which comprise on the one hand those formed by reactions and associations of all-carbon nanotubes with foreign atoms, molecules and compounds, and on the other hand, composites, obtained by incorporating carbon nanotubes in various matrices. Finally, we will provide a list of applications currently on the market, while skipping the potentially endless and speculative list of possible applications
