ABSTRACT

Objective: To conduct a geospatial analysis of suicide deaths among young people in the state of Paraná, southern Brazil, and evaluate their association with socioeconomic and spatial determinants. Methods: Data were obtained from the Mortality Information System and the Brazilian Institute of Geography and Statistics. Data on suicide mortality rates (SMR) were extracted for three age groups (15-19, 20-24, and 25-29 years) from two 5-year periods (1998-2002 and 2008-2012). Geospatial data were analyzed through exploratory spatial data analysis. We applied Bayesian networks algorithms to explore the network structure of the socioeconomic predictors of SMR. Results: We observed spatial dependency in SMR in both periods, revealing geospatial clusters of high SMR. Our results show that socioeconomic deprivation at the municipality level was an important determinant of suicide in the youth population in Paraná, and significantly influenced the formation of high-risk SMR clusters. Conclusion: While youth suicide is multifactorial, there are predictable geospatial and sociodemographic factors associated with high SMR among municipalities in Paraná. Suicide among youth aged 15-29 occurs in geographic clusters which are associated with socioeconomic deprivation. Rural settings with poor infrastructure and development also correlate with increased SMR clusters.

ABSTRACT

Este artigo apresenta um Sistema Baseado em Conhecimentos (SBC) para auxiliar no Diagnóstico Clínico das Crises Epiléticas (CE). Foi baseado na classificaçäo por tipo de crise da International League Against Epilepsia/ILAE81. O objetivo do sistema é obter um conjunto de sintomas apresentado pelo paciente, classificar o tipo de crise e indicar um provável diagnóstico. Para fazer o tratamento da incerteza será utilizado o Teorema de Bayes. O modo de classificaçäo utilizou as técnicas da Inteligência Artificial Simbólica através do Shell Kappa-PC e o paradigma de Orientaçäo a objetos

ABSTRACT

Com o objetivo de desenvolver sistemas automatizados de aquisiçäo de conhecimento para auxiliar na classificaçäo de crises epilépticas, este artigo apresenta um Sistema de Auxílio ao Diagnóstico Clínico de Crises Epilépticas, baseado na metodologia KADS (Knowledge Acquisition and Design Structure). Os métodos utilizados pelas ferramentas, tanto para a aquisiçäo como representaçÝo do conhecimento, representam o escopo da Engenharia do Conhecimento. O objetivo do sistema é obter conjuntos de sintomas apresentados pelo paciente e descrever um provável diagnóstico. O modo de classificaçäo utiliza as técnicas de IA simbólica, através do "shell Kappa-PC"e foi baseado na classificaçäo por tipo de crise da Liga Internacional Contra Epilepsia/ILAE. O sistema encontra-se na fase de teste e manutençäo das regras que fazem parte do módulo de propagaçäo do foco epiléptico
