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

Cartografia do trabalho de agentes penitenciários: reflexão sobre o “dispositivo prisão”

The Brazilian prison system is going through a serious crisis, not only due to the growth in the number of prisoners and the consequent overcrowding of prisons, but also for the violation of human rights, institutionalization and difficulty in social rehabilitation of inmates. Furthermore, the harmful effects of the prison system affect their workers, who generally are not prioritized by researchers, health programs and government policies. The literature pointing to some consequences of work in prison, among them, the mental illness, stress, alcohol abuse, etc., but little is known about this profession, their problems, the difficulties of their work routine, so as subjective processes involved. So, what are the effects of this work in the prison in the lives of correctional officers? What strategies developed to address the work in prison? This research aims to analyze the effects of this work in the prison in the lives of correctional officers from the state prison in Parnamirim, located in the metropolitan region of Natal-RN. Within the theoretical and methodological perspective of institutional analysis and cartography were carried conversation circles, interviews, in addition to participant observation of the correctional officers work’s routine. The results point to a working routine marked by the performance of procedures that involve risk to the worker, generating situations of tension and stress. Besides, the culture of violence (which is implemented in jail everyday) as well as the training and initial learning of the profession, are responsible for the militarization process of the subjectivities of the correctional officers, producing hard subject, disciplined, stiff, likely to violent practices and other rights violations. Other mapped effects relate to the acquisition of knowledge about the human (“psy” knowledge) responsible for forging the conception of the criminal as "dangerous subject", which, in turn, acts as subjectivity vector in the daily life of prison guards by setting up a way of life crossed by fear and insecurity outside the work environment. Produces a control in the open about their lives and their families, limiting them with regard to family and community life and the realization of leisure activities in public spaces. In this sense, it appears that the arrest acts producing “bad meetings” (from Espinosa's perspective), once it produces sad affections responsible for weakening the conatus, limiting the possibilities of action of these subjects. Although agents develop some strategies to deal with the difficulties of working in prison (among which stand out the development of other professional or leisure activities, spirituality / religiosity and the ability to separate the labor moments from those of their the personal lives, is advocated that such strategies do not offer significant resistance, since they do not question the contemporary legal-criminal logic. The thesis presented supports the proposals of penal abolitionism to present other conceptions of crime and justice through the invention of other practical and conceptual strategies.

Aplicação de agentes remineralizantes sobre o esmalte clareado: eficácia contra o manchamento por café

The aim of this study was to evaluate the influence of remineralizing agents on the susceptibility of enamel cleared by the coffee pigmentation during office bleaching. Fifty bovine incisors were selected and randomly assigned into 5 groups (n = 10) on the basis of remineralizing agents: G1 gel hydrogen peroxide to 35% (control group); G2, hydrogen peroxide gel and a 35% gel 2% neutral fluorine; G3, hydrogen peroxide gel and a 35% nanostructured calcium phosphate gel, G4, hydrogen peroxide gel and a 35% casein fosfoptídia-phosphate and amorphous calcium folder; G5 hydrogen peroxide gel to 35% without mineralizing agent. All groups exception G1 (control group) were subjected to pigmentation soluble coffee according to the manufacturer's guidelines. The samples were immersed in coffee at temperature of 55° C, 1 time a day for 4 minutes. Color changes were performed by Easyshade spectrophotometer at CIE Lab method before and after 3 whitening sessions. Data were analyzed by analysis of variance ANOVA. The results showed statistically significant differences between the remineralizing substances for the parameters L *, a *, b * ΔE (p <0.0001). The L * values for the group G5, and the b * for G2 and G5 groups differed from the control group. After the 3rd whitening session, Fluor's group (G2) and that without mineralizing agent (G5) showed ΔE values less than the control group that did not undergo pigmentation. It was concluded that only the nanoclusters remineralizing agents Phosphopeptides Casein-Amorphous Calcium Phosphate and Calcium Amorphous phosphate were able to reduce the coffee interference whitening efficacy of hydrogen peroxide.
