Dança de salão: história e evolução

A dança surgiu desde os primórdios da humanidade, quando os povos mais antigos dançavam, para a chuva e para o sol, para seus Deuses e para as pessoas mortas ou pelo simples fato de se comunicar. A partir do século XV, ela passou a ser executada nos grandes salões dos palácios, e algumas dessas danças são a valsa, o minueto e a quadrilha. Surgiu, então, a Dança de Salão, sendo que, cada região tinha suas danças características. No início do século XX começam as primeiras competições de dança e uma organização e padronização delas, buscando sua inserção nos Jogos Olímpicos. A dança de salão chegou ao Brasil com a Família Real, e após sua popularização, sofreu influência da cultura africana, que deu origem a novas danças, como o maxixe, o samba, o choro, a lambada, o forró entre outros. A dança como esporte chegou ao Brasil há pouco tempo, com a criação da Confederação Brasileira de Dança de Salão. Com essa profissionalização da Dança de Salão e mesmo pelo seu caráter lúdico, hoje, existem muitos praticantes. Este estudo teve a finalidade de fazer um levantamento histórico, que possa contribuir e enriquecer a quantidade de estudos nesta área, além de possibilitar àqueles que buscam a obtenção de informações relevantes sobre a dança de salão.

A prática pedagógica das lutas nas academias de ginástica

The fights are one of the most elementary manifestations of body culture, which are also constituted by sports, dances, games, and others. They are present in a lot of different ways, being very diverse among themselves. However, there is no consensus or agreements in the literature about the pedagogical practice of these modalities in fitness centers, sport clubs and sports centers. How do the teachers teach in these environments? What strategies do they use? How do they organize the contents? In what subjects they are based to execute the teaching and learning process? In this way, the objective of this study was to analyze some classes from different styles of fights/ martial arts teachers, trying to find what are their focus, goals, methodologies, classes’ dynamics and didactical and pedagogical procedures, aiming to check what is the focus of fights/ martial arts´ pedagogical practice in non-formal education. For this, it was selected one experienced teacher from the following modalities of fights from oriental origin: karate, judo, jiu jitsu and kung fu. The methodology used in this study consisted first in a literature review about the fights and sports pedagogy. Furthermore, there was one field research of qualitative nature, whose methods of data collection were divided in two: systematic observations of some classes of each teacher and semi-structured interviews with each teacher after the observation process, looking deeper into the pedagogical practice of these modalities. The results were analyzed through a content analyze, crossing the informations acquired with the instruments used. In addition to the description of these teachers and their classes, there was a classification of information, arriving the following categories: ritual and ceremony, tradition and discipline, didactical and pedagogical procedures ...(Complete abstract click electronic access below)

Análise do consumo de energia elétrica e da eficiência energética em uma indústria de processamento de madeira

In the industries of wood processing (sawmills), where timber is sawn in equipment such as band saws, circular saws, trowel, thicknessers, among others, that mechanically transform this resource and use of electric motors, which are not unusually poorly scaled working or overloaded, often a factor that is not found in these industries and has fundamental importance in the production process is energy efficiency that is achieved by both technological innovation and through all the practices and policies that aim to lower energy consumption, lowering energy costs and increasing the amount of energy offered no change in generation. For both during the design of an electrical installation, both overall and in various sectors of the installation, investigations are necessary, considerations and uses of variables and factors that put into practice the theme of energy efficiency. Therefore, in this paper, these factors were calculated and analyzed for a wood processing industry (sawmill) in the municipality of Taquarivaí - SP, namely: active power, power factor, demand factor and load factor. Where they were small in relation to the literature, these events that occur when devices are connected at the same time and due to the conditions of processing the wood, where the engines have large variations in electricity consumption during the unfolding of the same, due to efforts with the load and idle moments between each machining operation in the equipment

A imagem do técnico Bernardinho na opinião de alunos graduandos e professores de Educação Física escolar

A importância da mídia no mundo atual é evidente, pois ela exerce muita influência no âmbito da cultura corporal de movimento, que engloba lutas, danças, ginástica, conhecimento sobre o corpo, esporte e jogos, conteúdos de extrema importância para a formação do cidadão, ditando fazeres sobre as diversas práticas corporais e criando novos modelos de consumo. Dentro desse contexto o ídolo esportivo é intercambiável, negociável e consumível como imagem. Sendo assim a representação que um ídolo exerce sobre o indivíduo (telespectador) é referência de atitudes e a mídia contribui para a construção dessa imagem. Por causa dessa exposição, o técnico de vôlei Bernardo Rocha de Rezende passou a ter maior ascensão no cenário esportivo nacional, resolvi realizar esse estudo para investigar a opinião de alunos graduandos em Educação Física e professores da Educação Física escolar sobre a imagem do técnico Bernardinho. Objetivo: O objetivo do trabalho é investigar como a imagem do técnico Bernardo de Souza Rezende (Bernardinho), influenciada pela mídia, é interpretada por alunos graduandos em Educação Física e professores de Educação Física Escolar.

Desgaste e rugosidade superficial de um cimento de ionômero de vidro nanoparticulado

To compare the abrasion wear resistance and superficial roughness of different glass ionomer cements used as restorative materials, focusing on a new nanoparticulate material. Material and Method: Three glass ionomer cements were evaluated: Ketac Molar, Ketac N100 and Vitremer (3M ESPE, St. Paul, MN, USA), as well as the Filtek Z350 (3M ESPE, St. Paul, MN, USA). For each material were fabricated circular specimens (n=12), respecting the handling mode specified by the manufacturer, which were polished with sandpaper disks of decreasing grit. The wear was determined by the amount of mass (M) lost after brushing (10,000 cycles) and the roughness (Ra) using a surface roughness tester.

Results: Except for the composite, significant loss of mass was observed for all glass ionomer cements and the ΔM was comparable for all of them. Significant increase in roughness was observed only for Vitremer and Ketac N100. At the end of the brushing cycle, just Vitremer presented surface roughness greater than the composite resin. Conclusion: All glass ionomer cements showed significant weight loss after 10,000 cycles of brushing. However, only Vitremer showed an increase of roughness greater than the Z350 resin, while the nanoparticulate cement Ketac N100 showed a smooth surface comparable to the composite.

Protocolo radiográfico para a instalação de mini-implantes: descrição da técnica

In the last decade mini-screws have gained popularity in orthodontics field and a correct placement of mini-screws is a critical point to the success of the skeletal anchorage. A careful clinical and radiographic diagnostic before insertion mini-screw is an essential requirement to achieve the central point of the radicular septum. The correct application of these pre-surgical procedures should avoid possible iatrogenic damages in periodontal ligament, dental roots, nasomaxillary cavities, or even important vascular tissues. As of today, periapical radiographs is a regular pre surgical procedure during mini-screw insertion technique. Nevertheless, accurate execution of the radiographic parallax technique can offer to us useful and precise radiographic images, to decide the right local insertion of mini-screws in to the septum bone. The purpose of this paper is to describe the ¬application of new positioning circular guides in conjunction with a ¬parallax radiographic protocol before placement of orthodontic mini-screws.

Entre os muros da escola: o saber experiencial emergente nas aulas de educação física da periferia

This study aimed to analyze the teachers´ knowledge of a physical education teacher network state of São Paulo. The interviewed reported having problems regarding the use of the court, especially because there is invasion of the community to smoking marijuana and/ou playing football, revealing the predominance of experiential knowledge to work in a new school, whose location and local culture do not seem to prioritize this social space as learning, dissemination and preservation of other bodily manifestations of the process of human civilization. It was found in such a setting an imbalance of the relative strengths of power between teacher and students, from schools, football and drugs in relation to body movement culture, it being understood that the relationships between these individuals are interdependent and dynamic. Finally, it urges an integrated process in educational, family, social and political fields from the perspective of balancing forces in relation to the use of that space, providing conditions for teaching and propagation of content (games, sports, gymnastics, dances and fights) of the body movement culture.

Microbialitos da formação Codó (Aptiano Superior) às margens do rio Tocantins em São Miguel do Tocantins (TO)

The southwestern region of the São Luís-Grajaú Basin has a rare outcrop of the Codó Formation (upper Aptian) with seven outstanding microbialite bioherms along the left margin of the Tocantins river, near Imperatriz (MA). Resting on sandstones of the Grajaú Formation, the Codó Formation presents: 1) a 20 cm thick basal calcilutite with gypsite pseudomorphs and some fossil tree stems; 2) metric dark shales with carbonate nodules and thin intercalated carbonate layers, enclosing some microbial laminites; 3) a 2 cm thick upper breccia composed of microbialite fragments and other carbonate clasts, with halite hoppers on the top; 4) the carbonate bioherms, which partially overlie the extensive shales and interrupt them laterally, as well as the breccia. The bioherms in the northern part of the outcrop are thicker (<2 m) and have interbedded dark shales, whereas the southern are thinner and continuous in the vertical direction. In general, they are composed of irregular gently to strongly wavy microbial laminites, sometimes with pseudocolumnar to conical lamination. All microbialites with highest synoptic relief (<20 cm) look like columnar stromatolites on weathered lateral expositions. In plan view, the horizontal sections of these microbialites are circular to slightly elliptic, sometimes forming very small channels (N60W) filled with fine breccia. The highest bed of the northern bioherm has mixed microbial laminites and columnar stromatolites, where intercolumnar spaces were filled with microbialite clasts, fish bones, plant fragments and very small probable crustacean coprolites. Several fractures and deformation in this upper bed indicate an initial brecciation process probably caused by subaerial exposure. In microscopic scale, the lamination is smooth, diffuse, defined by subtle granulation differences of very fine granular calcite crystals within micrite, but oxide levels, dissolution surfaces or thin precipitated calcite veneers...
