The concept of ontoloy as a tool for knowledge organization and representation, which is not yet stable, is analyzed in two spanish journals of information science, namely “Scire: representación y organización del conocimiento” and “Ibersid: revista de sistemas de información y documentación”, both published by the University of Zaragoza. The term "ontology" and its variations were searched in the fields of title, keywords and abstract. A corpus of eighteen articles was obtained. The approaches to ontologies were classified into four categories of analysis: conceptualization, comparison, application and new applications. It was observed that the way which the concept of ontologies is treated in both periodicals is in consonance with their editorial policies. The term ontology is suffering a process of meta-terminologization, from the field of philosophy towards information science, a fact that deserves further and more vertical studies.

The school geographic knowledge must remain in line with theoretical advances produced by academic geographical knowledge. This is important for guarantee much better quality of education which is offered in schools. In this context, there are some important questions: do the teaching manual of geography for the basic level are updated according to the geographical knowledge produced by academia? Do the teachers of Geography in the basic education level have accompanied the theoretical and methodological innovations produced recently by geographical science? Through a research conducted with 51 teachers of Geography, who working in public schools in Marília, and after an analysis of geographic knowledge transmitted by textbooks used in most schools, the goal of this paper is to present some response to these questions. The research with teachers and the analysis of the contents of the textbooks were guided by one principal issue: the meaning of region.

The focus of this work is to present an example of refutation of the concept of element inside the seventeenth-century scientific revolution, mainly through Robert Boyle’s The Sceptical Chymist. On the first section of this paper the notion of element as considered by the ancient Greeks in Aristotle’s Physics and modern chemists in Paracelsus will be briefly presented. After that in the second section Boyle’s deconstruction of the idea of element will be exposed considering his argumentation of why this notion is prejudicial to the study of nature. Finally, in the third section follows the constructive stage in which a new hypothesis is presented (the corpuscular hypothesis) as the best option to replace the notion of element.

The objective of this essay is to make a connection between E. P. Thompson and Georg Lukács seeking rescue the ontological foundations of the concept of “experience”, as used by Thompson. At first, we present the category of experience in Thompson and then, category of work and the ontology of social being, according to Lukács. Approximate the concrete historical analysis developed by E. P. Thompson of reason dialectical-materialist presupposed in the ontology of social being of Georg Lukács is a contribution to overcoming the poverty of reason, just so you can achieve the necessary dialectical understanding of the category of experience that while social praxis is modeled the work category.

The increasing demand for alternative fuels lead to the search for solutions to use these fuels in old equipments and bring for new equipments the necessity of alternative fuels based burners. As a solution for these necessity the Gas Interchangeability`s studies came in evidence, because it studies the possibility of changing one fuel for another without changing the initial condition. In integrated industries, as most of steel industries, there is a link between process, the byproducts of one process are used as fuel for other process. There are new conditions for the equipments, that will be developed for these fuels, but even in these industries there will be situations which the byproduct won`t be available, and the process cannot stop. Using the gas interchangeability`s concepts is possible to work with security in both cases. Using alternative fuels in fossil fuel based burners and having a back-up solution for new technology burner. But using these new solutions were verified that there are some cases which the interchangeability`s methods does not work with satisfactory results, and for this reason, this study came to develop a new concept for the Method of Wobbe Index to evaluate the possibility to increase the range of the satisfactory results

The work aims to analyse the concept of economics as the science of scarcity is distorced in the newspaper Folha de Sao Paulo. Neoclassical economists characterize the economy as the science that is concerned with the welfare of the people, satisfying their needs. However, the economy in the newspapers of the mainstream media appears in contexts where only the profit of companies and businesses are addressed, leaving aside the problem of economic inequality, unemployment, working conditions and other issues that are also part of economy, but they are hardly concerns of journalists. In this work, the object of study was the notebook Market and content analysis followed the criteria of Bardin (1977). Ten words were chosen in the category science of scarcity and ten words were chosen in the category science of abundance. From these categories, a careful reading was done, counting how many times each word appeared in the newspaper. Also paid attention to the words that appeared and contexts in which they fell journalistic genre. In a second step, interviews were conducted with journalists from economics to know what they mean by the economy and what the guidelines are more common. Data collection and interviews contributed to the interpretation and confirmation on whether or not the distortion of the concept of economy and how it happens

The quality control is of great importance for the development of any organization, mainly for providing an assurance of delivering high quality services and goods for the consumers. Quality can be defined by the word „change‟, for the company which intends to implement a quality control system must be open to changes. This can be noticed from the JURAN concept (1992 In SILVEIRA ET AL., 2002): “Quality is to fit for usage”, i.e., depending on the goal, the situation and the consumer, quality is seen in different ways, since each one has different wishes and opinions. Taking in to account the availability of means such as norms, theories and tools, that contribute for an efficient quality management system, this discrepancy of opinions and the lack of objectivity of this concept can be solved, since through the analyzes of these means one can set quality standards, i.e., market references which fulfill both consumers and builders demands. Thus, the quality concept ceases to be something so abstract, non-measurable, to become a more objective concept. Finally, the goal of this work is to analyze the quality concept through bibliographic studies and possible consumers‟ enquires, aiming at the building industry, and show how the quality, often taken as something abstract, can be a measurable and objective concept, that benefits both the consumer as well as the enterprise of this branch

Esta monografia teve como objetivo demonstrar as diferentes concepções culturais do corpo ao longo de diferentes épocas e como os padrões sociais estabelecidos influenciam diretamente a maneira de visualizar esse corpo. Os meios de comunicação do século XX se desenvolveram de maneira vertiginosa, ficando mais acessíveis a população e aumentando a influência sobre esta. A geração fitness do início da década de 1980, que tinha como objetivo incentivar a prática de exercícios físicos para a população, acabou sendo amplamente divulgada pela mídia e exercendo grande influencia na sociedade. O padrão de corpo, bastante divulgado na sociedade atual, consiste em mulheres jovens, magras, e com o corpo bem delineado e homens fortes e musculosos. O corpo ficou banalizado. A mídia impõem o corpo ideal para toda a sociedade utilizando de inúmeras propagandas, com pessoas famosas e bem sucedidas relacionando muitas vezes o sucesso delas com o seu corpo. Várias pessoas acabam utilizando métodos nada saudáveis para a obtenção desse corpo ideal. Porém, isso pode causar inúmeras complicações de saúde e em alguns casos, a morte. O corpo perfeito, que deveria significar saúde, está virando sinônimo de doença e obsessão.

A alta incidência da cárie no Brasil vem despertando muito interesse para estudos que visem combatê-la. Tem-se observado a procura pela utilização de produtos naturais (plantas medicinais e resinas) que buscam atividade contra a principal bactéria causadora da cárie, que é o Streptococcus mutans, entre estas a geoprópolis (Melipona scutellaris). Todavia, apesar de os estudos mostrarem ação destes produtos de origem animal contra este micro-organismo, muitas vezes a baixa substantividade (bioadesão) deste material ao substrato determina uma baixa efetividade. Este estudo promoveu o desenvolvimento de um sistema líquido cristalino objetivando aumento da substantividade da própolis. Foram desenvolvidos sistemas constituídos por dispersão de quitosana, ácido oleico e álcool cetílico propoxilado e etoxilado (Procetyl® AWS), de acordo com o diagrama de fases ternário. Foram selecionadas 3 formulações, as quais foram submetidas a ensaios de microscopia de luz polarizada, análise de textura, bioadesão e reologia. Os resultados mostraram que os sistemas são viáveis para incorporação do extrato de própolis, aumentando sua bioadesão em ensaios in vitro

Baseado nas evidencias atuais de crescimento e expansão da atuação profissional do educador físico, em particular a sua atuação como prestador de serviços, ou seja, o personal trainer; que vende seus serviços, ou produtos relacionados à aptidão física e a relação promissora desta atuação, é que nos motivou a desenvolver este trabalho que segue por uma pesquisa bibliográfica de evidencias do histórico e perfil do personal trainer quanto aos conceitos culturais, sociais e psicológicos deste profissional, em seguida levantamos questões relacionadas à formação acadêmica do personal trainer e os pontos diferenciais deste profissional. Tais como a necessidade de conhecimentos que vão alem do âmbito acadêmico, pois se trata de um profissional prestador de serviços o que foge da regularidade da formação convencional. Portanto neste trabalho procuramos evidenciar estas e outras questões (como ética e profissionalismo), que podem levar este profissional a uma carreira de sucesso ou fracasso. Para isso existe uma necessidade fundamental de que se entenda que o personal trainer como prestador de serviços esta surgindo dentro de uma profissão já consolidada (Educador Físico), porem esta assumindo características próprias, como a necessidade de conhecimentos específicos da profissão. Concluímos, portanto que esta promissora atuação do educador físico necessita de atenções especiais e de um processo de formação diferenciado e que não podemos deixar que a nossa profissão se vulgarize e se venda por migalhas, pois esta é a grande chance do profissional se impor e conquistar o desejado respeito diante as profissões da área da saúde
