Caminhos para a universalização dos serviços de água e esgotos no Brasil: a atuação das entidades reguladoras para indução da eficiência dos prestadores de serviços

The deficit of water and sewerage services is a historic problem in Brazil. The introduction of a new regulatory framework, in 2007, presented ways intending to overcome these deficits, among them, the providers efficiency improvement. This thesis aims to analyze the regulators performance regarding its ability to induce the efficiency of the Brazilian water and sewerage services providers. To this end, an analytical approach based on a sequential explanatory strategy was used, and it consists of three steps. In the first step, the Data Envelopment Analysis ( DEA ) was used to measure the providers efficiency in 2006 and 2011. The results show that the average efficiency may be considered high; however significant inefficiencies among the 29 analyzed providers were detected. The ones in the Southeast region showed better performance level and Northeast had the lowest. The local and the private providers were more efficient on average. In 2006 and 2011 the average performance was higher among non-regulated providers. In 2006 the group regulated by local agencies had the best average performance, in 2011, the best performance was the group regulated by the consortium agencies. To analyse the second step was used the Malmquist Index, it pointed that the productivity between 2006 and 2011 dropped. The analysis through decomposing Malmquist Index showed a shift of technical efficiency frontier to a lower level, however was detected a small provider s advance towards the frontier. Only the Midwest region recorded progress in overall productivity. The deterioration in the total factor productivity was higher among regional providers but the local ones and the private agencies moved quickly to the frontier level. The providers regulated from 2007 showed less decrease on the total productivity and the results of the catch up effect were more meaningful. In the last step, the regulators standardization activity analyses noted that there are agencies that had not issued rules until 2011. The most standards topics discussed in the issued rules were the tariff adjustments and the setting of general conditions for the provision and use of services; in another hand, the least covered topics were new technologies incentive and the introduction of efficiency-inducing regulatory mechanisms and productivity gains for price reviews. Regulators created from 2007 were more active proportionately. Even with the advent of the regulatory framework and the creation of new regulatory bodies, the evidence points to a reality in which the actions of these agencies have not been ensuring that providers of water and sewage, regulated by them, has achieved better performance. The non- achievement of regulatory goals can be explained by the incipient level of performance of the Brazilian regulatory authorities, which should be strengthened because of its potential contribution to the Brazilian basic sanitation department

Prática de coordenação pedagógica e concepções acerca da atuação em psicologia escolar: desvendando um contexto, repensando caminhos

Considering the necessary approaches with the quotidian of the pedagogical field mentioned in the recent productions in Psychology about the insertion of psychologists in the school field, the objective of this work was to know and to understand the dynamics of functioning of a team of pedagogical coordination, intending to produce reflections on the possibilities of action in school psychology with these professionals. Our field of research was the Municipal School Teacher Emília Ramos (EMPER), considering its peculiar history, distinguished by a constant effort of achievement of the school success by its pupils. As subject of the study, six pedagogical coordinators participated, who worked at the school in the diurne turns, where regular classrooms of 1º cycle of basic education functioned. As procedures, we use participant observations and open interviews, focusing the activities performed by the coordinators and its possible demands to psychology. We use the analysis of content for the production of results. These results evidenced a work of coordination realized on a structured routine, but flexible, centered around the activity of conduction of groups of studies with the teachers. We grouped the demands to psychology in four thematic groups: diagnosis and attending the pupils; orientation to the families, contribution in the formation of the professionals and clinical listening of the professionals of the school. In this way, it is made clear that, in a context where happens a well articulated and consistent pedagogical work, the possible performance in school psychology is not scrumbled or confused with social and pedagogical practical others which many times takes attendance. With these information, we expect to contribute for the theoretical and practical elaborations, in Psychology and the Pedagogy, compromised with the success of the educative work realized in the public schools

Caminhos e descaminhos da adesão ao tratamento anti-hipertensivo :um estudo com usuários do Pacha (Programa de Assistência e Cuidado da Hipertensão Arterial) do Hospital Universitário Onofre Lopes

The high blood pressure is a multifactorial chronic disease which possesses emotional and social features in the illness appearance and evolution and in the adherence to the treatment which involves a decision-making through patient so that he or she process the necessary changes on harmful living habits. Adhesion, traditionally, it is referred to the patient to answer to the doctor orientations or of other health professional, about the appearance to the appointment with a doctor, about the use of medicine or lifestyle changes and maintaining this adhesion is the main problem to be overcame. It is expected the adhesion will ever be a continual, stable and satisfactory action, disregarding the complexity of subjectivity processes which permeate the sicken. This research aimed to investigate the difficulties which the person with high blood pressure has to adhere to the treatment, from the signification processes which give sense to the actions dealing with the adhesion. The study was carried out with 48 users of assistance program to the high blood pressure patient from Hospital Universitário from Natal RN, between 40-65 age. The answers were submitted to a double analysis process: 1) answer systematization in categories and codes and admission in statistical program SPSS (Statistical Package of Social Science), for generation of descriptive statistics; 2) Sense and signification analysis which permeated the deepener statement and interpretatively. The greater difficulties found are present on low-salt and law-calorie diets, in the dealing with everyday feeling and stress, being these factors cited as direct motive to the high blood pressure, regardless of interviewee s sex. It is observed there is not adhesion, but adhering, as an experienced everyday process. This work contributes with its results, assessing the used strategies by program with the aim of increasing the adhesion rates

Determinação do ponto de máximo carregamento de sistemas de potência utilizando o fluxo de carga desacoplado rápido parametrizado

Os métodos de fluxo de carga por Newton-Raphson e fluxo de carga desacoplado rápido convencionais são considerados inadequados para a obtenção do ponto de máximo carregamento de sistemas de potência, devido à problemas de mal-condicionamento neste ponto crítico e na sua vizinhança. Neste ponto a matriz Jacobiana do método de Newton-Raphson torna-se singular e considera-se que não são mais válidas as hipóteses de desacoplamento P-V e Q-teta utilizadas para a formulação do método fluxo de carga desacoplado rápido. No entanto, mostra-se neste trabalho, que com pequenas modificações, as versões XB e BX do fluxo de carga desacoplado rápido tornam-se adequadas para a obtenção do ponto de máximo carregamento. Estas novas versões modificadas são comparadas entre si com o intuito de explicitar suas características, assim como da influência da atuação dos limites de geração de potência reativa e de tap's de transformadores. Os resultados obtidos para os sistemas testes do IEEE (14, 30, 57 e 118 barras) mostram que as características de convergência das versões originais são preservadas. Além disso, durante o traçado das curvas PV, os diversos métodos podem ser comutados entre si possibilitando o cálculo de todos os pontos da curva com um número reduzido de iterações.

Famílias privadas de liberdade: a saga da violência vivenciada por adolescentes que trilham os áridos caminhos da criminalidade

This paper has as its main focus the relation between the infringement act and the adolescents families social economical problematic, who obey the social educational deprivation of freedom at CEDUC in the district of Pitimbu RN, establishing in the theme Children and Adolescents, with the objective of showing how these families breed in the social economical and cultural political aspect. It also seizes who those adolescents are and their family members in their social aspect and as those families face their daily activities. The focus on the social matter, family, adolescent, infringement act, exclusion, inclusion formed the analysis categories which made myths and reality possible, taking into consideration the infringement act in our society. The data collection showed that those families conditions of life are of poverty. Families originated from low social classes, 62.5 % coming from the countryside and living with a daily income ranging from R$ 0,31 to R$ 8,31. Their level of education is low; there is lack of human and citizenship rights and no professional qualification whatsoever. It questions the degrading social exclusion suffered by millions of Brazilian people due to social, political and infringement economical problems. Has this favored the infringement practice? How to confirm the families lack of competence having the social vulnerability? Are the Public Political Institutions really performing the way they should? Are they really carrying out their role as they should? We have noticed that from then on, the necessity of understanding the exclusion/inclusion suffered not only in an imprecise and empty way, but understood as processes of integrative exclusion or ways of delinquency, where the excluding is not only the only one who has lack of material care but the one who is seen or recognized as a person, is not being treated as one. The effort of this paper provided an approach to our object, and the seizing of a close relation between the infringement act and the exclusion process or inclusion suffered, which are submitted to families of those adolescents who deprive of freedom

Os caminhos da transição agroecológica: uma análise das experiências da agricultura familiar camponesa no território dos Vales do Curu e aracatiaçu-CE

This study examines peasant family farming from an agroecological perspective. It intends to analyze the changes resulting from the transition from conventional to agro-ecological agriculture in the daily practices of farmers articulated associated with the Network of Agroecological and Solidarity Farmers of the Curu and Aracatiaçu Valleys Territory, the locus of this empirical research, and a space which has highlighted the social dynamics of agroecological innovation, as well as articulating environmental exchanges and knowledge development. As a way to further that goal, we seek to identify the forms of social organization previously present in the daily lives of these subjects, in addition to grasping the determinants that lead or led them to adopt agroecology, noting the need to verify the forms of resistance, and the strategies adopted by farmers and how they articulate collectively. Through the historical and dialectical methods, we seek to take the implications of technical modernization of agriculture under the conditions of production and reproduction of peasants and thus situate the emergence of agroecology, a focus that is born as a counterpoint to conventional patterns of agricultural development based on the paradigm of the Green Revolution. We structured this study around the trajectory of agroecological farmers that developed and internalized agroecological practices, processes, and organizational forms. For the analysis, we used theoretical and methodological frameworks from literature related to field research. The systematization and analysis of experiments revealed that agroecological transition is a broad process of change, not restricted to technical matters. We observed changes in production practices, diversification of production and feeding practices, ecological awareness, production autonomy, and organizations formed to face the challenges resulting from the imposition of the dominant agricultural development model that combines environmental degradation, land ownership concentration, and wealth concentration

Umidificação e aquecimento do gás inalado durante ventilação artificial com baixo fluxo e fluxo mínimo de gases frescos

JUSTIFICATIVA E OBJETIVOS: em pacientes sob intubação traqueal ou traqueostomia, a umidificação e o aquecimento do gás inalado são necessários para a prevenção de lesões no sistema respiratório, conseqüentes ao contato do gás frio e seco com as vias aéreas. O objetivo da pesquisa foi avaliar o efeito do sistema respiratório circular com absorvedor de dióxido de carbono do aparelho de anestesia Cícero da Dräger, quanto à capacidade de aquecimento e umidificação dos gases inalados, utilizando-se fluxo baixo (1 L.min-1) ou mínimo (0,5 L.min-1) de gases frescos. MÉTODO: O estudo aleatório foi realizado em 24 pacientes, estado físico ASA I, com idades entre 18 e 65 anos, submetidos à anestesia geral, utilizando-se a Estação de Trabalho Cícero da Dräger (Alemanha), para realização de cirurgias abdominais, os quais foram distribuídos aleatoriamente em dois grupos: grupo de Baixo Fluxo (BF), no qual foi administrado 0,5 L.min-1 de oxigênio e 0,5 L.min-1 de óxido nitroso e fluxo mínimo (FM), administrando-se somente oxigênio a 0,5 L.min-1. Os atributos estudados foram temperatura, umidade relativa e absoluta da sala de operação e do gás no sistema inspiratório. RESULTADOS: Os valores da temperatura, umidade relativa e umidade absoluta no sistema inspiratório na saída do aparelho de anestesia e junto ao tubo traqueal não apresentaram diferença significante entre os grupos, mas aumentaram ao longo do tempo nos dois grupos (BF e FM), havendo influência da temperatura da sala de operação sobre a temperatura do gás inalado, nos dois grupos estudados. Níveis de umidade e temperatura próximos dos ideais foram alcançados, nos dois grupos, a partir de 90 minutos. CONCLUSÕES: Não há diferença significante da umidade e temperatura do gás inalado utilizando-se baixo fluxo e fluxo mínimo de gases frescos.

Proposta e implementação de uma arquitetura reconfigurável híbrida para aplicações baseadas em fluxo de dados

The increase of applications complexity has demanded hardware even more flexible and able to achieve higher performance. Traditional hardware solutions have not been successful in providing these applications constraints. General purpose processors have inherent flexibility, since they perform several tasks, however, they can not reach high performance when compared to application-specific devices. Moreover, since application-specific devices perform only few tasks, they achieve high performance, although they have less flexibility. Reconfigurable architectures emerged as an alternative to traditional approaches and have become an area of rising interest over the last decades. The purpose of this new paradigm is to modify the device s behavior according to the application. Thus, it is possible to balance flexibility and performance and also to attend the applications constraints. This work presents the design and implementation of a coarse grained hybrid reconfigurable architecture to stream-based applications. The architecture, named RoSA, consists of a reconfigurable logic attached to a processor. Its goal is to exploit the instruction level parallelism from intensive data-flow applications to accelerate the application s execution on the reconfigurable logic. The instruction level parallelism extraction is done at compile time, thus, this work also presents an optimization phase to the RoSA architecture to be included in the GCC compiler. To design the architecture, this work also presents a methodology based on hardware reuse of datapaths, named RoSE. RoSE aims to visualize the reconfigurable units through reusability levels, which provides area saving and datapath simplification. The architecture presented was implemented in hardware description language (VHDL). It was validated through simulations and prototyping. To characterize performance analysis some benchmarks were used and they demonstrated a speedup of 11x on the execution of some applications
