Os levantamentos epidemiológicos são importantes para o conhecimento da prevalência e tipologia das doenças bucais, podendo-se a partir dos dados coletados, planejar, executar e avaliar ações de saúde. É necessário, no entanto, que haja rigor metodológico que garanta reprodutibilidade, validade e confiabilidade, e que haja uniformidade de procedimentos para permitir comparações nacionais e internacionais. A iniciativa da Organização Mundial da Saúde (OMS) na assessoria à realização de levantamentos tem se mostrado extremamente útil, estimulando o estabelecimento de padrões de procedimentos que podem ser utilizados em todos os países. em 1991 foi publicada a edição em português da terceira edição do Oral Health Surveys - basic methods, de 1987, um manual que objetiva fornecer instruções para a realização de levantamentos epidemiológicos e tal publicação passou a servir de base a estudos realizados em diversos locais do Brasil e do mundo. O objetivo deste trabalho, é analisar criticamente a metodologia para Levantamento Epidemiológico em Saúde Bucal da OMS, na tentativa de contribuir para o aperfeiçoamento da mesma. de acordo com a presente análise, foram encontrados pontos relevantes para consideração, referentes à amostragem, à calibração dos examinadores e aos critérios para a avaliação de saúde bucal e necessidades de tratamento. Concluiu-se, em nível de recomendação, que, devido ao caráter dinâmico do conhecimento científico e, levando-se em consideração as diferenças regionais com relação ao padrão de desenvolvimento das doenças bucais, as propostas de padronização de levantamentos devem ser periodicamente revisadas. É provável, ainda, que outros pontos importantes não tenham sido detectados nesta análise, tornando-se premente ampliar esta discussão para toda a comunidade odontológica.

Despite the frequent use of stepping motors in robotics, automation, and a variety of precision instruments, they can hardly be found in rotational viscometers. This paper proposes the use of a stepping motor to drive a conventional constant-shear-rate laboratory rotational viscometer to avoid the use of velocity sensor and gearbox and, thus, simplify the instrument design. To investigate this driving technique, a commercial rotating viscometer has been adapted to be driven by a bipolar stepping motor, which is controlled via a personal computer. Special circuitry has been added to microstep the stepping motor at selectable step sizes and to condition the torque signal. Tests have been carried out using the prototype to produce flow curves for two standard Newtonian fluids (920 and 12 560 mPa (.) s, both at 25 degrees C). The flow curves have been obtained by employing several distinct microstep sizes within the shear rate range of 50-500 s(-1). The results indicate the feasibility of the proposed driving technique.

The cell block technique is widely used and recognized by health professionals, but lacks in information regarding the specific contribution of this method to veterinary medicine. The cytology of bone marrow and buffy coat (cellular portion of the hole blood) are widely used in the diagnosis of neoplastic and nonneoplastic diseases, and also for the detection of infectious agents. Although the importance of these samples is widely recognized, there is no information about the use of buffy coat and bone marrow samples in the cell block procedure among the research material used for this paper. This work aims for the cell block standardization for canine buffy coat and bone marrow samples. We collected 110 buffy coat samples and 44 bone marrow samples for the cell block preparation, and 68.2% of buffy coat and bone marrow proved to be viable at the end of the procedure. The 95% ethanol fixatives along with the 20 minute processing steps (absolute ethanol, xilol and paraffin, 3 of each) were crucial for the quality of the material both in microtomy and optical microscopy. Mechanical separation of the buffy coat proved to be easy and cheap and was used to compose the cell block technique. In this research we emphasized the importance of cell block standardization in order to develop and easy, inexpensive and reproducible method, regardless of any of the professionals' limitations.

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

This work aims to study the movement periodically interrupted realized by four handmade toys. Such movement can be studied by nonlinear dynamics, but this topic is not covered in the general undergraduate courses in Physics. The study presented aim to observe, search, identify and measure physical quantities characteristic of toys according to the information provided by the dynamic, in this case, the formalism of moment of forces and energy. It also allows an approach to non-formal education in physics, since the measures and instruments differ from formal laboratory approach. These toys are unknown examples of simple machines studied in Mechanics and allow to illustrate passive walkers in Robotics

Jazz brings to the surface discussions about globalization and its unfolding. The development of such music style allows a reflection about the processes that influence 20th century culture, thus enabling a closer look into debates that involve cultural industrialization and standardization in such context. Horkheimer‟s and Adorno‟s work deal with this theme, considering culture as something standardized, a result of the process that fits into the industrial production mold. Morin goes further in this discussion, suggesting the emergence of a mass culture as a third culture. Later, Latin-American authors Ortiz and Canclini bring up new tones and approaches to the globalization through culture theme

The aim is to analyze a corpus of remote sensing in order to identify acronyms in English and then search for their equivalents in Portuguese. The research is based on the approach of Corpus-Based Translation Studies (BAKER, 1995), Corpus Linguistics (BERBER SARDINHA, 2004), and Phraseology (PAVEL, 2003). The program WordSmith Tools version 6.0 is used. The results show that there is no standardization in these translations.
