Implantar um Centro de serviços Compartilhados (CSC) é uma prática atualmente utilizada tanto por empresas brasileiras quanto em outros países para padronizar processos, otimizar recursos e reduzir custos, permitindo que suas unidades operacionais se dediquem as suas atividades fim, deixando as atividades comuns (transacionais) sob suporte e responsabilidade do CSC. De outro lado, as áreas de Saúde Ocupacional e Meio Ambiente (SSMA) têm importante papel em grande parte das empresas, tendo em vista que a gestão da saúde e segurança dos empregados da empresa está sob sua responsabilidade. O objetivo deste trabalho é analisar a viabilidade e identificar os resultados da inserção de atividades relacionadas à SSMA em um Centro de Serviços Compartilhados (CSC). Para cumprir esse objetivo, optou-se por adotar como metodologia de pesquisa, além do levantamento bibliográfico, um estudo de caso em uma empresa multinacional atuante nos segmentos de Mineração, Logística, Energia, Óleo e Gás e Entretenimento. Os dados coletados permitiram uma comparação entre a bibliografia pesquisada e o estudo de caso realizado. Os resultados mostraram que o mapeamento dos processos da área de SSMA foi essencial para desafiar os processos existentes, gerando oportunidades de melhoria de desempenho organizacional ao identificar interfaces críticas e, sobretudo, criar bases para implantação do SAP. Este mapeamento estruturado de processos permitiu, ainda, reduzir custos no desenvolvimento de produtos e serviços, falhas de integração entre áreas e promover melhoria de desempenho organizacional, além de ser uma excelente ferramenta para o melhor entendimento dos processos atuais e eliminação ou simplificação dos que necessitam de mudanças.

This research work intends to carry out a study focused on the dynamic between development, poverty reduction and conservation of natural resources. To consider this relationship to the region chosen was the micro-region of Eastern and Western Seridó in the state of Rio Grande do Norte. In recent years, several studies (Araújo, 2011; BASTOS, 2009) have pointed out that after a period of economic crisis in its tripodproductive, formed by the activities of farming, cotton farming, mining and faced in the eighties, this region of the State of Rio Grande do Norte, has not only shown signs of economic recovery but also improve their social indicators. On the other hand, studies of desertification as the view of the state of RN (produced in cooperation between the Government of RN and research institutions) and the Sustainable Development Plan of Seridó (ADES, 2000), indicate that there is an ongoing French process of degradation of natural resources that is capable of compromising the ability of sustaining such a system. To verify this reality and likely finding this relationship, this work is adopted for this study, the analysis of evolution of secondary data from official bodies such as the IBGE on HDI, per capita income and other social indicators between 2000 and 2009. Here is another time of the survey analysis of qualitative data collected from interviews with institutions of academic intervention in nature, researchers at the Federal University of Rio Grande do Norte (UFRN) State agencies that address the issue of the Middle Environment in Seridó: Institute for Sustainable Development of the NB (IDEMA) and the Brazilian Institute of Environment and the Amazon (IBAMA) and institutions of direct intervention in the region, as the Agency's Sustainable Development Seridó (adhesive) and the Joint Semi-Arid (ASA). After crossing data from quantitative and qualitative, it was found that the dynamics of the region's economic Seridó Potiguar partially answers the improvement of social indicators of poverty. Contribution by the State in this shared stock transfer income. Regarding the influence of productive restructuring in the region on issues of environment, it is noted that the ceramic tile industry, responsible for the absorption percentage of the population with limited ingress into the urban economy, given the low education, accounts for the increase of susceptibility to the ongoing process of desertification in North Seridó Rio Grande. We conclude finally that the guarantee of increased income, freedom and conservation of natural resources ensures primarily by changing the beliefs and values, especially on the part of the business sector, which use natural resources so predatory, aimed at maintaining their rates of return on investment. And concomitantly, the synchronization between technological change, through the use of new energy sources, and institutional change.

O tema foi escolhido em função da sua relevância global, atualidade e importância para a população brasileira. A valorização de resíduos sólidos tem sido um tema central das políticas ambientais desde a década de 1970. Desde então, os resíduos são vistos não só como parte da problemática ambiental, mas também como um recurso produtivo e uma fonte de energia. A pesquisa proposta neste estudo tem o objetivo de analisar os benefícios da valorização energética de resíduos sólidos urbanos para a sociedade, e analisar as possíveis dificuldades que se colocam diante desta alternativa energética

In this dissertation we propose a Teaching Unit of Physics to teach content through environmental discussions of the greenhouse effect and global warming. This teaching unit is based on a problem-methodological intervention from the application of the method of the Arch of Charles Maguerez. The methodological foundations of the thesis are embedded in action research and this is structured in five chapters: the first chapter deals with the Physical Environment (FMA) as a subject in Degree Courses in Physics in Brazil, bringing the concern of how this discipline has been taught. We started the first chapter explaining the reasons behind the inclusion of the discipline of Physical Environment in a Physics Degree Courses. Then we did a search on the websites of Institutions of Higher Education, to know of the existence or not of this discipline on curricular. We then analyzed the menus to see what bibliographies are being adopted and what content of Physics are being worked, and how it has been done. The courses surveyed were those of Federal and Federal Institutes Universities. Thus ended the first chapter. Given the inseparability between studies in Physics Teaching and studies on competencies, skills and significant learning, wrote the second chapter. In this chapter we discuss the challenge of converting information into knowledge. Initially on initial teacher training, because even if this is not our focus, the study is a discipline on the upper reaches, therefore, offered to future teachers. Then we talked about the culture of knowledge, where we emphasize the use of a teaching approach that promotes meanings taught by content and make sense to the student. We finished the third chapter, making some considerations on skills and abilities, in order to identify what skills and competencies were developed and worked during and after the implementation of Curriculum Unit. The third chapter is the result of a literature review and study of the radioactive EarthSun interaction. The subjects researched approach from the generation of energy in the sun to topics stain solar coronal mass ejections, solar wind, black body radiation, Wien displacement law, Stefan-Boltzmann Law, greenhouse effect and global warming. This chapter deals with material support for the teacher of the aforementioned discipline. The fourth chapter talks about the arc method of Charles Maguerez; Here we explain the structure of each of the five steps of the Arc and how to use them in teaching. We also show another version of this method adapted by Bordenave. In the fifth and final chapter brought a description of how the method of Arc was used in physics classes of Environment, with students majoring in Physics IFRN Campus Santa Cruz. Here, in this chapter, a transcript of classes to show how was the application of a problem-based methodology in the teaching of content proposed for Physics Teaching Unit from the environmental discussion about the greenhouse effect and global warming phenomena
