Este trabalho propõe a inclusão de informação extraída a partir da modelagem de processos para auxiliar pequena empresas do setor madeireiro no controle de fluxo de materiais e estoques. Para isto são apresentados conceitos de modelagem de processos e sistema MRP I (Material Requirement Planning). Desta forma foi realizado um estudo detalhado sobre o sistema citado e posteriormente sobre as possibilidades de aplicações de uma modelagem de processos. Em seguida, chegou-se a proposta de modelagem para o tipo de empresa em questão. A modelagem é constituída por cinco etapas, onde é sugerida a inclusão de tendência de demanda para maior controle de necessidades de materiais. O resultado obtido, a modelagem, pode ter grande utilidade no controle de fluxo de materiais em pequenas empresas, acarretando menores problemas no atendimento de demanda e acumulo de estoques e assim aumentando sua competitividade.

Esta pesquisa pretende contribuir para a compreensão das relações estabelecidas entre estagiários de cursos de licenciatura e professores da Educação Básica, que os recebem em suas salas de aula. Mais especificamente, tem-se o objetivo de investigar os processos de aprendizagem que ocorrem no encontro entre duas gerações profissionais docentes. Nesse sentido, questiona-se: de que maneira são estruturadas as relações estabelecidas entre professor titular e estagiário na escola, como ocorrem os primeiros contatos entre as duas partes, que vínculos são então estabelecidos e que relações formativas se desenvolvem no cotidiano do estágio. Tais percepções foram propiciadas pelas entrevistas e observações realizadas e analisadas sob ótica das “relações intergeracionais na docência” (SARTI, 2009), que pressupõem atenção especial a algumas categorias, tais como: geração (MANNHEIN, 1982), identidade e ciclo de vida profissional docente (HUMBERMAN, 1992; TARDIF, 2010). A pesquisa possibilitou análises que sugerem que o fator geração profissional deva ser sempre balizado com informações sobre a história de vida profissional dos sujeitos, já que, de acordo com os dados reunidos,tais experiências pessoais exercem influências em suas relações com as novas gerações profissionais. A partir desta investigação, foi possível perceber que as relações intergeracionais na formação docente envolvem fatores sutis e importantes, que dizem respeito a aspectos relativos à geração profissional dos sujeitos, mas também a sua geração social (MANNHEIN, 1982) e ao ciclo de vida profissional docente (HUBERMAN, 1992). Esse conjunto de fatores exercem influências significativas para os contatos formativos entre estagiários e professores experientes no magistério

Nesta pesquisa estudamos as relações entre cultura e processos de subjetivação a partir da identificação das marcas da chamada cultura da malandragem tal como se expressa por meio da sensibilidade de uma obra de arte. Cartografamos na peça teatral “A ópera do malandro”, de Chico Buarque de Holanda, as marcas do movimento do corpo do malandro que nos permitem identificar a constituição de um princípio ético e de uma escolha estética ao transitar nas fronteiras da marginalidade e da legalidade estabelecidas no interior da cultura brasileira. Estudamos o “corpo” e o “movimento” em uma dimensão política situados na cultura. Para isso assumimos a concepção de cultura como um campo de materialidade configurada por forças em permanente tensão. Investigamos na “Ópera do Malandro” as configurações da subjetividade observando um corpo que aprende a dançar para “não dançar na vida”.

Technological advances and the availability of computational resources have been facilitating the collection and processing of data. Thus, the natural tendency of the monitoring processes is the simultaneous control of various quality characteristics. In automated processes, observations are generally autocorrelated. Studies with univariate graph for processes have shown that the autocorrelation reduces the ability of this signal changes in the process. In this paper, we study the multivariate autocorrelated processes. Through simulations are obtained properties of graphs, monitoring the mean vector, the properties of graphs VMAX, in monitoring the covariance matrix, and the properties of graphs MCMAX, the simultaneous monitoring of mean vector and covariance matrix. Conclude that increasing the autocorrelation and the number of variables being monitored, reduces the power of the graphics in signal of a special cause

The need for housing in Brazil is very large, and despite government efforts to address this issue, the housing deficit is too large. When analyzing markets without this problem, it is concluded that one of the factors that influence this model is the construction adopted by Brazilian society that is in masonry. Alternatively, the system can be used in constructive Wood-frame. To apply this system in Brazil, one can say that the workmanship and the materials available to meet the demand would be created in a short period of adjustments and capabilities, but identifies himself as one of the biggest problems the planning and management of works. And one of the tools for solving this problem is to use a checklist of the activities of constructive process, avoiding forgetting or not aware of the activities necessary to complete the project

The transportation of oil through pipelines raises a concern related to safety and environmental impacts they may cause, especially when exposed to risks that affect their integrity. Among the natural phenomena that can affect the pipelines are erosion and landslides. Considering the large territory involving the pipelines, remote sensing tools have a great applicability for data acquisition. For this, visual analysis techniques were applied to perform change detection in order to monitor erosion features and landslides along a stretch of pipeline Rio de Janeiro – Belo Horizonte, in the state of Rio de Janeiro. The work involved the characterization of the study area as well as the erosion and landslide processes, through bibliographical data. The satellite image processing and the application of change detection techniques were developed in two scenes for the years 2002 and 2010. It was noted a small increase in the number of the identified features, however with regard to their area, a decrease of 21.7% was observed

In the last 60 years, many Brazilian cities practically doubled their population contingent. As a result of this process, there was an increase on the occupation level on unstable areas, from a physical point of view, and on the anthropogenic interventions at the natural ambient, reorganizing the existent process and forms. Thus, this work shows the results of the analysis of geomorphological changes deriving from urbanization processes at the Lavapés Stream watershed, located at Rio Claro county (SP). The goal of this work was reached by means of historical-evolutionary geomorphological cartography. To achieve this result, it had been prepared geomorphological and land usage charts for the years of 1962, 1988 and 2010, and a declivity chart. Those scenarios have been analyzed from the point of view of the General Systems Theory. The results were attached into an urban use restrictions chart, which allowed identifying the areas that should not be occupied, by geomorphological view and by environmental law restrictions

The competitiveness among global markets, the constant need for reducing manufacturing costs and also the growing environmental commitments are fueling the development of techniques for recovery residual parts generated by industrial processes. Among the various areas of a company, we highlight those that involve the processing of raw materials derived from oil, such as polymers (resins), which may take centuries to decompose in the environment and also present as a economic and environmentally strategic point. Thus, this study would examine the recovery of waste polypropylene, from the injection process of a major multinational in the field of home appliances through the recycling by a process comprising the milling, extrusion and chipping of waste material. Easy to deploy, this proposal aims to reduce levels negligible disposal (scrap) of these residues as well as the reintegration of the production process into pieces no visual and no structural importance, aimed at cutting costs and reducing environmental impacts caused. After the survey data in kilograms of waste material generated in a given period of time, and the study of changes in material properties, it would enable the reuse steadily in the injection process

The purpose of this work is to perform studies of mathematical modeling of the relationship of interaction occurring between microrganisms participants from wastewater treatment processes aimed at understanding, through simulations, such as inter-relationships can affect the performance of such units. The methodology was the implementation in FORTRAN computer language of mathematical models of microbial interactions. The first model addresses the interaction of bacteria-forming flakes and filamentous bacteria in activated sludge systems, which seeks to strike a balance between these bacteria to improve efficiency of the process. Another model is studied the interaction between bacteria and protozoa in activated sludge systems and analyzing the efficiency of the process, observing the changes in daily load. Microbial interactions in anaerobic reactors were dealt a third model, in which there is the mutualistic interaction between acidogenic and methanogenic bacteria. In a fourth and final model was examined the relationship between the bacteria Acinetobacter sp. and Gordonia sp., which are present in activated sludge systems, showing the competitive capacity of Acinetobacter sp. can control the growth of unwanted bacteria.

Esta pesquisa analisa a concepção do corpo a partir dos aspectos que explicitam suas implicações sobre as metodologias empregadas nas práticas de ensino em estudos biológicos como, por exemplo, a vivissecção, bem como sobre os efeitos observados nos corpos dos estudantes. Nossa pesquisa delimita o seu objeto de estudo em um recorte que considera a dinâmica de constituição do corpo em sua dimensão material, esta que se assenta nas condições biológicas do existir humano. Propusemos outra passagem pelo trânsito de territórios nos quais os nossos corpos se investem de simbolismo e de elementos oriundos do universo cultural. Esta passagem na metodologia da análise implica nossa condição de pesquisadores situados na fronteira que se desenha entre os estudos da Biologia, Filosofia e Psicanálise. Consideramos o corpo em sua constituição, mas analisamos os modos como esta base material vem sendo tratada nos processos de subjetivação da sociedade contemporânea. Assim, nosso recorte incide sobre o corpo que se faz no espaço que cada sujeito abre para as relações com a alteridade. Acrescentamos que ao optarmos pelo estudo sobre políticas de subjetivação a partir de suas implicações corporais, observamos o cuidado com este corpo que padece, não somente por um aspecto físico, compreendido como participante da ecologia da natureza, mas também como aquele que sustenta os sentimentos, emoções, compreendido como a ecologia dos ambientes grupais e o aspecto da constituição de si, compreendido como a ecologia do ambiente subjetivo.

The industries face increasingly fierce competition, so that differentiation becomes more and more difficult. In the case of the branch of machine tool industries this scenario is aggressive, those firms face competition from around the world, which have good quality and low price. This paper aims to propose the creation of a department to promote standardization in a company of special tools. The goal was achieved from survey of theories and applications of quality management, knowledge management and standardization, done by scholars in these areas, which added the use of qualitative study resulted in a proposal that contained not only the creation of this department as possible approaches that can be applied by him. This work is limited to the study of a company that manufactures special tools of the state of São Paulo, which despite its small size and limited number of employees, also presents common situations to other companies in the field, especially with regard to the behavior employees, and present good practices that can be implemented by any company
