No Brasil, a Eletrobrás, através do Programa Nacional de Conservação de Energia Elétrica (Procel) e em parceria com o Instituto Nacional de Metrologia, Normalização e Qualidade Industrial (Inmetro), lançaram a Etiqueta Nacional de Eficiência Energética em Edificações (ENCE), para edifícios comerciais, de serviços e públicos, reconhecendo edificações que reduzam o consumo de energia elétrica e água. Neste trabalho foi realizado um estudo de certificação energética e ambiental de edificações, bem como a identificação de alternativas técnicas para o enquadramento em níveis mais adequados e correspondente estudo de viabilidade econômica. Como estudo de caso, o edifício da Fundação existente no Campus de Guaratinguetá da UNESP foi analisado de acordo com os preceitos da avaliação de desempenho de ambas as metodologias. Com base nos resultados obtidos, foram realizadas sugestões de tecnologias e modificações possíveis de serem implantadas / The LEED system (Leadership in Energy and Environmental Design) is a methodology for evaluating the energetic and environmental performance of buildings throughout their life cycle, aiming to guide actions for the concept of green building and provide a standard for measuring the size on environmental projects. In Brazil, Eletrobras, through the National Program for Energy Conservation (PROCEL) and in partnership with the National Institute of Metrology, Standardization and Industrial Quality (Inmetro), launched the Label National Energy Efficiency in Buildings (ENCE), for commercial buildings, and public service, recognizing buildings that reduce the consumption of electricity and water. In this research report it was presented an environmental and energetic certification of buildings study, as well as the analysis of technical solutions for the framework in more appropriate levels, and corresponding economic feasibility study. As a case study, the Foundation's existing building on the campus of UNESP at Guaratinguetá was analyzed in accordance with the principles of performance evaluation of both approaches. Based on these results, suggestions were made of possible technologies and changes being implemented

The focus of following thesis is to evaluate selected aspects of animal hygine of livestock husbandry in term of welfare in foothills area. The study covers two private-owned farms in the same area, however with entirely different attitude to stock husbandry. Welfare itself is not easy to quantify and to mesure, but we can pass judgment on the over-all comfort of stock using folowing indicators: health condition, reproductive potential, production efficiency etc.. All above memtioned indicators consist of many aspects. The most important are, alimentation, diet, technology of stockmanship and stress. This thesis involves comparsion of animal welfare and its economical utilization and if the condionts of stock husbandry provided by farmers response welfare standarts . To summe up, the technology of free housing respect more the ethological demand of stock.

Com maior vigor nas últimas décadas do século XX, a eficiência das atividades estatais passou a ser contestada por múltiplos atores sociais, que tomam como paradigma de gestão os resultados alcançados pelo setor privado. Nesse novo cenário, emergiram movimentos globais de reforma do aparelho estatal, a fim de impor às atividades públicas a eficiência com que supostamente atua o mercado, uma vez que o debate acerca da eficiência do capital público é uma questão de grande relevância para o campo de estudo relativo às diversas áreas do conhecimento, às atividades macro e microeconômicas e à própria dinâmica social. Conseqüência dessa atenção crescente destinada à análise, e contestação, da eficiência do gasto público e das atividades a ele imbricadas, é a histórica institucionalização, pela legislação brasileira, da eficiência como um dos princípios fundamentais da administração pública, como propõem o decreto-lei n. 200/67 e a emenda constitucional n. 19/98. Nesse cenário, em que a eficiência das atividades públicas é crescentemente almejada e refutada, tomam projeção e relevância métodos e técnicas que tratam desse aspecto. Adquire importância, por conseqüência lógica, pesquisas destinadas a sistematizar as contribuições e experiências sobre a utilização de tais métodos. Entretanto, poucos trabalhos extrapolam o caráter meramente aplicativo das técnicas, explicitando-se a carência por bibliografia que sistematize, sob diversos aspectos, as aplicações já realizadas, nesse campo do conhecimento. Dessa forma, esta pesquisa objetiva identificar e sistematizar os métodos existentes para avaliar a eficiência dos investimentos públicos em infra-estrutura na literatura internacional e nacional. Contribui-se, portanto, com subsídios teóricos e analíticos para pesquisadores em gestão pública, administradores estatais e cidadãos que se ocupam com a análise da eficiência das atividades públicas, principalmente em infra-estrutura. / With larger energy in the last decades of the 20th century, the efficiency of the state activities passed to be answered by multiple social actors, that you/they take as administration paradigm the results reached by the private section. In this new scenery, global movements of the state\'s reform apparel emerged, in order to impose to the public activities the efficiency where supposedly the market acts, once the debate concerns the efficiency of the public capital is a subject of great relevance for the field of relative study to the several areas of knowledge, to activities macro and microeconomics and to the own social dynamics. The consequence of this growing attention destined to the analysis, and reply, the efficiency of the public expense and of those activities, that\'s the historical institutionalization, which for the brazilian legislation, of the efficiency as one of the fundamental beginnings in public administration, as they propose the law n. 200/67 and the constitutional amendment n.19/98. In this scenery, in what the efficiency of the public activities is increasingly longed for and refuted, they take projection and relevance methods and techniques that treat that aspect. It acquires importance, for logical consequence, researches destined to systematize the contributions and experiences about the use of such methods. However, few works extrapolate the character merely application of techniques, explicated if the lack for bibliography that systematizes, under several aspects, the applications already accomplished, in the field of knowledge. In that way, this objective research to identify and to systematize the existent methods to evaluate the efficiency of the public investments in infrastructure of the international and national literature. It is contributed, therefore, with theoretical and analytical subsidies for researchers in public administration, state administrators and citizens that are in charge with the analysis of the efficiency of the public activities, mainly in infrastructure.

It uses as reference the implementation of FUNDEF - Fund for Maintenance and Development of the Fundamental Education and Valorization of Teaching - to identify the impact of the decentralization on the students’ performance, as well as on the school’s efficiency. For this, a panel data from the school census between 1996 and 2006 is used. First, the impact of decentralization on students’ performance - failure, dropout and age-grade distortion rates - is estimated through the use of differencesin- differences models. An analysis on how the different local conditions might affect these results is also presented. After this, the efficiency of municipal and state schools is compared using a double bootstrap procedure that takes into account the effects of the local context on the estimated efficiency scores. Results indicate that there was an increase in failure rates and, more importantly, these results might be affected by local characteristics such as city size and political participation. Related to the efficiency estimations, results indicate that state schools are relatively more efficient and, local conditions would impact differently the efficiency of these two school types.

M.Com. (Business Management) / More than fifteen years have gone by since the fall of the apartheid regime in South Africa (SA) in 1994. From 1994, it became critical for every institution of the government to work towards the transformation of the public sector. The ultimate aim of this transformation has been to bring about a better life for all. However, the pace at which improvement in the general life of people from the historically disadvantaged communities is moving slowly. The best weapon that can be employed to ensure that life is improved is through the provision of quality education. There is a serious need for an improvement in the educational system of our country which is counted among the lowest in the world in terms of literacy and mathematics. This situation is continuing to prevail despite the fact that South Africa has some of the best infrastructure in the world. The researcher has undertaken this study with the assumption that the Supply Chain Management (SCM) plays a critical role in the improvement of service delivery and cost reduction as well as inventory reduction. Initially, the SCM was applied in the private sector only where the focus is on profitability. However, for the past few years, the SCM has been overlapping into the public sector. The SA government is amongst the first to adopt SCM as a tool to improve service delivery and to reduce costs. The focus of the SCM in the SA public sector is efficiency, effectiveness and the economic use of resources in the context of development and equity. There are many potential benefits that can be gained in the public sector when SCM is implemented effectively. These benefits include improved service delivery, inventory reduction and cost reduction. The Department of Basic Education (DoBE) is investing heavily towards the improvement of the standard of education in the country. Despite this, there are still learners who attend schools without all the necessary textbooks, the basic source of information for learning. The shortage of books prevails even in Limpopo Province which is one of the poorest provinces in SA. As a poor province, learners in Limpopo do not have easy access to other sources of information such as the internet and only very few schools in Limpopo Province have libraries. These learners rely on the textbooks to get information and therefore the failure to provide adequate textbooks to these learners leaves them with nothing to depend on for their studies. Consequently, their performance at schools is affected to the point that they may fail at the end of the school year.

In this article we develop a comprehensive conceptual framework for resource efficiency indicators with a consistent link of resource use to the socio-economic system and activities therein as well as to the natural system and its ecosystem functioning. Three broad groups of indicators are defined: (1) resource use indicators representing pressures on the environment; (2) resource efficiency indicators relating resource use indicators to the socio-economic side; and (3) environmental impact indicators linking resource use impacts on the state of the natural system. Based on this conceptual framework we develop a structure for possible resource efficiency indicators and conduct a RACER evaluation on the Relevance, Acceptance, Credibility, Easiness and Robustness of indicators. With the RACER evaluation, we identify areas where indicators are well established and available as well as areas where indicators still need further development or even need to be designed first.

The objective of this research was to characterize the performance of a downflow bubblecontact (DBCA) hypolimnetic aerator — Speece Cone-. The effect of two key design factors, inlet water velocity and the ratio of gas flow rate to water flow rate on four standard units of measure was examined: (a) the Oxygen Transfer Coefficient, KLa, corrected to 20°C, KLa₂₀ (hr­-¹), (b) the Standard Oxygen Transfer Rate, SOTR (g0₂.hr­-¹) (c) the Standard Aeration Efficiency, SAE (gO₂kWhr­-¹), and (d) the Standard Oxygen Transfer Efficiency, SOTE (%). Two sources of oxygen, Pressure Swing Adsorption (PSA) oxygen (87% purity) and air, were compared. KLa₂₀, SOTR, and SAE increased with an increase in the ratio of gas flow rate to water flow rate for both air and oxygen, over a range of 0.5% to 5.0%; while SAE deceased. An increase in inlet water velocity resulted in a decrease in KLa, corrected to 20°C, SOTR, and SAE, but an increase in the SOTE. Treatments on air showed similar, but much less dramatic effect of the gas flow rate to water flow rate ratio and water inlet velocity on KLa₂₀, SOTE, SAE, and SOTE, when compared to treatments on PSA oxygen. The best performance was achieved with an inlet water velocity of 6.9-7.6 ms­-¹ and oxygen flow rate to water flow rate ratio of about 2.5%. At this combination, the SOTE was about 66-72%. / Applied Science, Faculty of / Civil Engineering, Department of / Graduate
