A eficiência e a racionalidade energética da iluminação pública têm relevante importância no sistema elétrico, porque contribui para diminuir a necessidade de investimentos na construção de novas fontes geradoras de energia elétrica e nos desperdícios energéticos. Apresenta-se como objetivo deste trabalho de pesquisa o desenvolvimento e aplicação do IDE (índice de desempenho energético), fundamentado no sistema de inferência nebulosa e indicadores de eficiência e racionalidade de uso da energia elétrica. A opção em utilizar a inferência nebulosa deve-se aos fatos de sua capacidade de reproduzir parte do raciocínio humano, e estabelecer relação entre a diversidade de indicadores envolvidos. Para a consecução do sistema de inferência nebulosa, foram definidas como variáveis de entrada: os indicadores de eficiência e racionalidade; o método de inferência foi baseado em regras produzidas por especialista em iluminação pública, e como saída um número real que caracteriza o IDE. Os indicadores de eficiência e racionalidade são divididos em duas classes: globais e específicos. Os indicadores globais são: FP (fator de potência), FC (fator de carga) e FD (fator de demanda). Os indicadores específicos são: FU (fator de utilização), ICA (consumo de energia por área iluminada), IE (intensidade energética) e IL (intensidade de iluminação natural). Para a aplicação deste trabalho, foi selecionada e caracterizada a iluminação pública da Cidade Universitária \"Armando de Salles Oliveira\" da Universidade de São Paulo. Sendo assim, o gestor do sistema de iluminação, a partir do índice desenvolvido neste trabalho, dispõe de condições para avaliar o uso da energia elétrica e, desta forma, elaborar e simular estratégias com o objetivo de economizá-la.

A Iluminação Pública (IP) está num momento de profundas mudanças, principalmente com a popularização da tecnologia LED e dos sistemas de controle a distância. O gestor de serviços públicos precisa conhecer a complexidade do uso final da IP para que possa gerir esse ativo direcionado às necessidades dos usuários, tendo em vista o dinamismo de evolução diária dos centros urbanos. Este estudo tem por objetivo desenvolver uma metodologia que permite levantar, cadastrar, diagnosticar e avaliar, o parque de IP existente em ambientes urbanos. Tem como questão de pesquisa: Como prover os gestores de serviços públicos de conhecimento da situação dos ativos de IP? Trata-se de uma pesquisa observacional e descritiva, desenvolvida em uma região que compreende uma área de 26,5 km², com uma população de 344.632 habitantes, localizada em uma região metropolitana brasileira. A metodologia aplicada divide-se em dois momentos: pesquisa documental e de campo. Inicia-se com um levantamento de documentações a respeito da vida pregressa do acervo, disponíveis nos escritórios da Concessionária de Energia local e da Prefeitura Municipal. Posteriormente procede-se uma identificação do perfil da cidade, onde o sistema de iluminação está inserido, buscando compreender como o sistema de IP instalado está integrado às necessidades da população. Essas primeiras ações visam recolher subsídios para a etapa seguinte, de levantamento técnico em campo, que buscou identificar não só os atributos de IP existentes para atualização cadastral, como também identificou anomalias que estavam atrapalhando o desempenho do sistema e a influência provocada pelo meio onde está inserido. A metodologia pode ser uma ferramenta que contribui para a gestão do serviço de IP inserida dentro dos centros urbanos, possibilitando a adoção de medidas de ajustes que visem dotar o acervo de IP de uma estrutura de manutenção direcionada para cada região da cidade, considerando sua especificidade e perfil dos usuários. Antes de qualquer adoção de novas tecnologias, como por exemplo lâmpadas LED, telecomando, etc., é imprescindível que se tenha um diagnóstico do acervo existente e a identificação do uso final da IP no meio em que se encontra.

Throughout our history as an actor, director and teacher, we appreciate comedic performances they proposed a dialogue with the public through the body language of the performers whose performances abdicate the use of speech of the actors. This way of representing, in the silence of the stage, caught our attention and sparked our curiosity about the subject, which is directly related to the poetic constructions of the body on the scene. Before initial readings on the subject, we begin to understand that for a long time in human history, especially in the West, understanding body was constructed from various epistemological looks disregarded the body as a unit, an incarnation of the subject in all . This kind of thinking, reflecting the philosophy of modernity, reverberated strongly about the aesthetic issues of art making, here specifically in Theatre. For several centuries the theatrical make up molded from various aesthetic elements, but ignoring the potential of embodiment of the artist, ie the theatrical text, for example, was considered for a long time, as the main element of the scene and gave little emphasis on dramaturgy elaborate body. With the emergence of reflections on the subject, brought especially from the early twentieth century, the perception of the body as a creative element and creator, also began to gain ground. Over time artistic practices began to glimpse the creative possibilities of the body, including rethinking its relationship with the text written with the spoken word. And as part of these new reflections on the body in the creation process, we proposed this research, we have entitled "A poetics of non-verbal body: a look at the comic on the scene." In our research on this subject, also seek to understand how the corporeality of the actor may give us clues to realize / build nonverbal body and comical scene. From this perspective we can analyze how could the construction of a comical and non-verbal dramaturgy from the phenomenology of laughter. And with that look, we want to point out some aspects and procedures, arising from reflections on corporeality and comedy, that constitute, among other possible, non-verbal construction methodology scenic.

The purpose of this research is to analyze different daylighting systems in schools in the city of Natal/RN. Although with the abundantly daylight available locally, there are a scarce and diffuse architectural recommendations relating sky conditions, dimensions of daylight systems, shading, fraction of sky visibility, required illuminance, glare, period of occupation and depth of the lit area. This research explores different selected apertures systems to explore the potential of natural light for each system. The method has divided into three phases: The first phase is the modeling which involves the construction of three-dimensional model of a classroom in Sketchup software 2014, which is featured in follow recommendations presented in the literature to obtain a good quality of environmental comfort in school settings. The second phase is the dynamic performance computer simulation of the light through the Daysim software. The input data are the climate file of 2009 the city of Natal / RN, the classroom volumetry in 3ds format with the assignment of optical properties of each surface, the sensor mapping file and the user load file . The results produced in the simulation are organized in a spreadsheet prepared by Carvalho (2014) to determine the occurrence of useful daylight illuminance (UDI) in the range of 300 to 3000lux and build graphics illuminance curves and contours of UDI to identify the uniformity of distribution light, the need of the minimum level of illuminance and the occurrence of glare.

In educational observed difficulty in train teachers to meet the medium and higher education needs, and one reason for this is the different experiences in the training of educators in relation to those found in the classroom. So often arise criticisms related to relevance and efficiency of degree courses, as regards the performance of its natural mission, which weakens the teacher training. Thus, improving the quality of education is very dependent on the initiatives of teachers, creating teaching alternatives to strengthen their performance in school. From this reflection, it is concluded that teacher training needs new educational proposals that qualify, and so can promote the formation of his students more adequately. Among the educational proposals as alternatives to initial teacher training may use the scientific theater (TC). Considering this possibility, this work has been proposed as investigate and discuss the influence of TC combined with experimentation in the initial training of future teachers in Chemistry who participate in the Groups Fanatics chemistry Theatre (UERN) and Chemistry on Stage (UFRN). Therefore, there was, in a first stage, theatrical essays based on the theater of the oppressed, and written dramaturgical scripts, a collaborative proposal. To incorporate experimentation in chemistry to theater rehearsals, there was a systematic literature search and after content analysis, were selected categories, materials and reagents easily accessible, easy procedures and implementation with low risk of accidents and easy care chemical waste. In the second part we identified: a) the beliefs of student teachers in the use of TC ally trial for initial training of chemistry teachers; b) the influence of TC ally to trial on learning of chemical concepts of high school students who attended the shows; c) the reasons for using or not TC ally to trial by chemistry teachers who participated in the TC group and currently work in the classroom. In this study, questionnaires and interviews were used, compounds, respectively, by a Likert scale and open questions. Quantitative data were analyzed by classical statistics the media, using as centrality measures the average, the concordance argument and the average deviation. Qualitative data were discussed according to content analysis, with categories that emerged from reading the answers. These analyzes concluded that the licensees have a positive view on the use of scientific theater for disclosure of the chemical for use in the learning of chemical concepts, pedagogical and disciplinary knowledge, and to form promotion strategy for research and extension at the University. They credit improvements in their initial training on the use of scientific theater combined with experimentation. The TC provides motivation for the construction of conceptual thinking in an informal way of chemical communication, allowing the student to expand their knowledge, not only favoring the phenomenological approach, but also the construction of chemical knowledge and the internalization of scientific concepts.
