Assessment and Comparison of Behavior Risk Factor Surveillance Systems for the U.S., Canada, and Italy.

Arana, Carolina 20 November 2009 (has links)
Behavior risk factors include health risk factors that increase a person's chances of developing a disease, such as having a high blood pressure, high blood cholesterol, tobacco smoke, physical inactivity, obesity or overweight, diabetes, poor nutrition, lack of sex education and car safety. They can be classified as: Background risk factors, such as age, sex, level of education and genetic compositions; Behavioral risk factors, such as smoking, unhealthy diet and physical inactivity; and Intermediate risk factors, such a serum cholesterol levels, diabetes, hypertension and obesity/overweight. This study describes a comparison and assessment of Behavior Risk Factor Surveillance Systems for the U.S., Canada, and Italy. The aim of this project is to assess and analyze the behavior surveillance systems of U.S., Canada and Italy, compare their strengths and weaknesses and provide recommendations that can be used as a guide for the design of new BRFS systems or the assessment of existing systems. The purpose of the assessment is to identify ways of improving the respective systems, and also to compare public health BRFS systems in the three different countries. The attributes used in the evaluation of the systems include simplicity, flexibility, data quality, acceptability, sensitivity, predictive value positive, representativeness, timeliness, and stability. The criteria and standards are based on the CDC Guidelines for Evaluating Surveillance Systems published on 1988 and updated on 2001.

No. of bitstreams: 1 Paulo Jose Melo Gomes Correa.pdf: 5684127 bytes, checksum: c4aae2b2365a502a84da14364cdf5d4d (MD5) Previous issue date: 2009-09-14 / This research presents studies involving Electricity Engineering and Oil and Biofuel Analytical Chemistry areas, whose objective is the perfectioning of chemical analysis steps for the Fuel Quality Monitoring Program, instituted by the National Agency of Petroleum and Biofuel - ANP, executed in the Maranhão State by the Laboratory of Analyses and Research in Analytical Chemistry of Petroleum and Biofuel - LAPQAP. For this, improvements were proposed for the Fuel Quality Control Multiagente System, and help for the decisions taking of the laboratory. The inclusion of new agents to the multiagent society is still considered, where the objective is to add a new technique automatized for chemical analyses, beyond additional functionalities. A fuel ontology was considered for the communication mechanism that will be shaped using 101 methodology, whose objective is the representation of domain knowledge of chemical analyses beyond supply of a communication language among the society agents. In order to reach the objectives we used Artificial Intelligence techniques, inference motor JESS (Java Expert System Shell), an ontology technology to represent the domain knowledge serving as vocabulary of the communication process, the middleware JADE (Java Agent DEvelopment framework) for environment execution with their improvements and the development methodology of multiagent systems named PASSI for the system modeling. / Esta pesquisa apresenta estudos envolvendo as áreas de Engenharia de Eletricidade e Química Analítica de Petróleo e Bicombustíveis, tendo como objetivo o aperfeiçoamento das etapas de análise químicas do Programa de Monitoramento da Qualidade de Combustíveis (PMQC), instituído pela Agência Nacional de Petróleo e Biocombustíveis ANP, executado no Estado do Maranhão pelo Laboratório de Análises e Pesquisa em Química Analítica de Petróleo e Biocombustíveis - LAPQAP. Para isto, são propostas melhorias no Sistema Inteligente de Monitoramento e Controle da Qualidade de Combustíveis SIMCQC utilizado pelo laboratório no auxilio a tomada de decisões. Propõe-se a inclusão de novos agentes à sociedade multiagente, tendo como objetivo aumentar a quantidade de técnicas análises químicas no SIMCQC. Para o mecanismo de comunicação é mostrada a criação de uma ontologia de combustíveis que foi modelada utilizando-se da metodologia 101, cujo objetivo é a representação do conhecimento do domínio de análises químicas e o fornecimento de uma linguagem de conteúdo para o mecanismo de comunicação dos agentes da sociedade. Para o alcance dos objetivos foram utilizadas técnicas de Inteligência Artificial, motor de inferência JESS (Java Expert System Shell), a tecnologia de Ontologia para representar o conhecimento do domínio e servir como vocabulário do processo de comunicação, o middleware JADE (Java Agent DEvelopment Framework) para execução do ambiente com suas melhorias e a metodologia de desenvolvimento de sistemas multiagente PASSI para a modelagem do sistema.
