    Com os avancos dos recursos da Word Wide Web, os beneficios obtidos sao incontestaveis tambem na area da educacao. Apesar de sua ampla disseminacao, podem apresentar falhas que os tornam inadequados. Uma das maneiras de se evitar os infortunios causados por websites mal estruturados seria a realizacao de avaliacoes de sua qualidade. Pesquisadores do Nucleo de Informatica em Enfermagem da Universidade Federal de Sao Paulo (UNIFESP) desenvolveram em parceria com o Departamento de Informatica em Saude da UNIFESP um website educacional em Primeiros Socorros. Considerando-se a relevancia do ensino e a necessidade de investir em ferramentas informativas de qualidade sobre o tema objetivou-se neste estudo: elaborar e validar instrumentos de avaliacao de website e avaliar o website em Primeiros Socorros. Tres instrumentos foram criados para avaliar a estrutura, o conteudo e a navegabilidade. Verificou-se que esses instrumentos foram adequados para o uso na avaliacao do website, por apresentarem niveis superiores ao Limite de Seguranca .0,70 estabelecido. Em relacao a qualidade do website, observou-se que o valor de Kappa foi de 0,047 e -0,062 na analise das respostas dos profissionais de informatica e da saude, respectivamente, indicando que nao houve concordancia nas respostas. No entanto, na analise da distribuicao das respostas dos avaliadores percebeu-se que, segundo os profissionais de informatica, a qualidade estrutural do website deveria ser revista e corrigida para torna-lo adequado. Ja em relacao a distribuicao dos escores assinalados pelos profissionais da area da saude observou-se que a qualidade de conteudo do website e boa e que deveriam ser feitas pequenas correcoes de alguns conteudos. A avaliacao da qualidade de navegabilidade do website, segundo a opiniao dos alunos e boa, conforme o escore obtido de 79,4%. Observou-se que tanto os profissionais da saude como os alunos referiram que a distribuicao dos links deveria ser melhorada, semelhante as recomendacoes dos profissionais de informatica. Concluiu-se que: os tres instrumentos elaborados foram considerados adequados para a utilizacao da avaliacao do website. A qualidade estrutural do website deve ser corrigida, para que o processo de navegacao seja adequado e embora a qualidade do conteudo seja boa, pequenas correcoes nas informacoes devem ser realizadas.

    Decision support system for the diagnosis of schizophrenia disorders
    (Associação Brasileira de Divulgação Científica, 2006-01-01) Razzouk, Denise [UNIFESP]; Mari, Jair de Jesus [UNIFESP]; Shirakawa, Itiro [UNIFESP]; Wainer, Jacques [UNIFESP]; Sigulem, Daniel [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    Clinical decision support systems are useful tools for assisting physicians to diagnose complex illnesses. Schizophrenia is a complex, heterogeneous and incapacitating mental disorder that should be detected as early as possible to avoid a most serious outcome. These artificial intelligence systems might be useful in the early detection of schizophrenia disorder. The objective of the present study was to describe the development of such a clinical decision support system for the diagnosis of schizophrenia spectrum disorders (SADDESQ). The development of this system is described in four stages: knowledge acquisition, knowledge organization, the development of a computer-assisted model, and the evaluation of the system's performance. The knowledge was extracted from an expert through open interviews. These interviews aimed to explore the expert's diagnostic decision-making process for the diagnosis of schizophrenia. A graph methodology was employed to identify the elements involved in the reasoning process. Knowledge was first organized and modeled by means of algorithms and then transferred to a computational model created by the covering approach. The performance assessment involved the comparison of the diagnoses of 38 clinical vignettes between an expert and the SADDESQ. The results showed a relatively low rate of misclassification (18-34%) and a good performance by SADDESQ in the diagnosis of schizophrenia, with an accuracy of 66-82%. The accuracy was higher when schizophreniform disorder was considered as the presence of schizophrenia disorder. Although these results are preliminary, the SADDESQ has exhibited a satisfactory performance, which needs to be further evaluated within a clinical setting.
