Avaliação de arquitetura de agentes emocionais : uma abordagem baseada em métrica de qualidade e na influência das emoções sobre usuários

There is a need for multi-agent system designers in determining the quality of systems in the earliest phases of the development process. The architectures of the agents are also part of the design of these systems, and therefore also need to have their quality evaluated. Motivated by the important role that emotions play in our daily lives, embodied agents researchers have aimed to create agents capable of producing affective and natural interaction with users that produces a beneficial or desirable result. For this, several studies proposing architectures of agents with emotions arose without the accompaniment of appropriate methods for the assessment of these architectures. The objective of this study is to propose a methodology for evaluating architectures emotional agents, which evaluates the quality attributes of the design of architectures, in addition to evaluation of human-computer interaction, the effects on the subjective experience of users of applications that implement it. The methodology is based on a model of well-defined metrics. In assessing the quality of architectural design, the attributes assessed are: extensibility, modularity and complexity. In assessing the effects on users' subjective experience, which involves the implementation of the architecture in an application and we suggest to be the domain of computer games, the metrics are: enjoyment, felt support, warm, caring, trust, cooperation, intelligence, interestingness, naturalness of emotional reactions, believabiliy, reducing of frustration and likeability, and the average time and average attempts. We experimented with this approach and evaluate five architectures emotional agents: BDIE, DETT, Camurra-Coglio, EBDI, Emotional-BDI. Two of the architectures, BDIE and EBDI, were implemented in a version of the game Minesweeper and evaluated for human-computer interaction. In the results, DETT stood out with the best architectural design. Users who have played the version of the game with emotional agents performed better than those who played without agents. In assessing the subjective experience of users, the differences between the architectures were insignificant

Doenças de Veiculação Hídrica em Trechos da Bacia do Rio Piranhas-Assu: ocorrência de bactérias oportunistas, caracterização epidemiológica e concepções de professores e agentes de saúde

Water is essential to life and all living organisms and their supply is necessary for economic development and quality of life of human populations, but their quality has been altered by human actions. In semi-arid northeast, the water is an issue of concern, especially its quality. This region is common to the construction of reservoirs that capture rain water, streams and temporary rivers in search of ease this situation, being intended for various purposes. Water scarcity is a limiting factor for the economic and social development of the region and contributes to the maintenance of waterborne diseases. About 80% of diseases that occur in developing countries are infected by waterborne pathogens. Therefore, this study aimed to determine in two environments that are part of semilênticos Armando Ribeiro Gonçalves reservoir, and a stretch of the river Assu, all located in the semiarid RN, the occurrence of opportunistic pathogenic bacteria; check the conceptions of teachers and health workers about the issues "waterborne diseases" and "bacteria" and a diagnosis of diarrheal diseases that affect the population in some municipalities of the semi-arid region of RN from a survey of epidemiological data. For identification of bacteria using commercial kits and the diagnosis of diarrheal disease was based on information from databases. The previous conceptions of teachers and health workers were obtained through questionnaires. The results confirmed the presence of opportunistic bacteria in the studied area, showing the importance of monitoring water quality. There was an under-reporting of cases of diarrhea pointing out flaws in the monitoring of Diarrheal Diseases and indicating the need to improve it. It was felt also the need to implement educational activities on topics dealt with both with teachers and health workers, since they were identified misconceptions on the subject

Geografia, turismo e meio ambiente: uma nova face do litoral dos municípios de Extremoz e Ceará-Mirim

La presente pesquisa contempla reflexiones referentes de la actividad turística en la organización socio-espacial en el litoral de las comarcas de Extremoz y Ceará-Mirim, región de la Grande Natal. Nuestro objetivo principal es el estudio de las transformaciones del espacio y de sus implicaciones socio-ambientales en curso en el proceso de producción del espacio turístico en el litoral de las referidas comarcas desde 1997 hasta 2007, momento de importancia publica-privada que, a partir del PRODETUR, tuvo la base para el incremento de las potencialidades turísticas. En este sentido, varias fueron las técnicas para una mejor compresión de las aspiraciones y de la percepción de los actores envueltos con la actividad turística (comerciantes, turistas, populación y poder publico local) para conocer cuales son sus consideraciones en cuanto a los cambios que proceden de la implantación de la actividad turística en el lugar, cuanto a la mejora de la calidad de vida, de la generación de empleo y de renta, comercialización, conservación, preservación del ambiente, cumplimiento de la legislación, afirmación cultural así como las acciones puestas en ejecución en las comarcas. Para tal necesidad, se buscó analizar los datos estadísticos a partir del uso de los cuestionarios con preguntas estructuradas y semi-abiertas como instrumento de colecta de información que les era correlacionada con la opinión de los actores locales de modo que podamos formar y entender los elementos básicos que son parte de los espacios turísticos en foco. Fueran utilizadas fotografías aéreas de las comarcas de Extremoz y Ceará-Mirim, provistas por el IDEMA, con la intención de percibir acerca de los cambios del espacio y las implicaciones socio-ambientales de la área en estudio. Concluimos en función de los resultados que el modelo de Turismo concebido por lo Brasil, estimulado y financiado por lo Gobierno Federal, está insertado en el contexto de la economía global y, por lo tanto, el Estado del Rio Grande del Norte, en específico los espacios litoraneos de las comarcas de Extremoz y Ceará-Mirim, que poseen características similares a este modelo, con sus particularidades, que si traduzca por la exclusión social, formas de apropiación privada de los espacios público y áreas de protección ambiental como las playas, las dunas y las lagunas, el desacato o no el cumplimiento de la legislación ambiental, aumento de las desigualdad de renta en una región que posee una problemática social grave y sin inversión, implantación de la infraestructura, ausencia de política pública local, donde los intereses económicos son prioridad delante de las aclamaciones populares. Se sugiere un repensar cuanto al modelo actual de desarrollo adoptado, que el planeamiento sea pautado en base a la participación integrada de los varios agentes implicados con la actividad turística, incluyendo en la medida del posible, las aspiraciones de la población local como precusoras de sus reales necesidades, donde esta acción interactiva contestará ciertamente en un esfuerzo significativo en la construcción de un nuevo paradigma, modelo del desarrollo sustentable, siendo posible superar gradualmente el incremento de la pobreza, de la exclusión y de los impactos ambientales, donde la calidad de vida sea factor fundamental
