Consciência corporal e educação física escolar: possibilidades de intervenção

The investigation about the body consciousness in school Physical Education had as main objective reporting a possibility of intervention, linking it directly to the contents of Physical Education and considering it as a crosscutting theme in this research. In this scope, we worked specifically with two contents of Physical Education - knowledge about the body and fights. During the study, we are going to discuss about teaching strategies for the themes of body awareness. To develop this work, we used the following study questions: how is treated the body consciousness in Physical Education and how it has been addressed in educational interventions? What are the difficulties found to the themes of body awareness on different issues of school Physical Education? How body awareness thematized in contents in Physical Education is received by the students and what are the attitudes demonstrated by them during the development of these lessons? Based from questions of study, we used the following methodological tools: participant observation, interviews, photographic records, debates, films, dramatizations and dynamics, which they were performed to stimulate students' critical thinking about their body and the other children s one. The research with ethnographic characteristics was conducted in two schools: one elementary school I, in Natal and one elementary school II, held in the municipality of the João Câmara, in the state of Rio Grande do Norte. We developed a structure in order that the three dimensions of contents conceptual, procedural and attitudinal were experienced by students. The work is structured in five chapters. At first, we made an introduction to justify the motivations that led us to write about body awareness at school. In the second chapter, we discussed reflection about the body and its possibilities of understanding, reflecting on the body and how this awareness was being treated in physical education classes at school. In the third chapter, dealing with the body awareness and dialogue with the Physical Education, we had made a theoretical approach, from authors such as CLARO (1988), NÓBREGA (2000), ARAGÃO (2004), MELO (2006), LORENZETTO and MATTHIESEN (2008) in order to situate the body consciousness and its relationship with physical education. In the fourth chapter, we talked about body awareness thematized in physical education contents: knowledge about the body and fights. We introduced the teaching experience developed in the school and we discussed with authors such as OLIVIER (2000), DARIDO AND RANGEL (2008), among others, about how was the reflection about the body leaving of these experiences. The fifth chapter was intended to closing remarks, in which we concluded that the body awareness, treated in physical education in school by sociocultural and historical aspects, it will contribute in building a man, a body and a society. Although the body consciousness is crafted in a few moments of Physical Education, based on the practices of body awareness or alternatives; in our proposal, we pointed out another perspective to work with body awareness, bringing its elements to permeate and pass through the contents of Physical Education. At work we can see a suggestion for that these experiences are carried out by other Physical Education professionals, obviously adapting the activities according to age and educational level of students

Desenvolvimento de um compósito de espuma rígida de poliuretana de mamona e fibras de sisal para isolação térmica

The search for sustainable technologies that can contribute to reduce energy consumption is a great challenge in the field of insulation materials. In this context, composites manufactured from vegetal sources are an alternative technology. The principal objectives of this work are the development and characterization of a composite composed by the rigid polyurethane foam derived from castor oil (commercially available as RESPAN D40) and sisal fibers. The manufacture of the composite was done with expansion controlled inside a closed mold. The sisal fibers where used in the form of needlepunched nonwoven with a mean density of 1150 g/m2 and 1350 g/m2. The composite characterization was performed through the following tests: thermal conductivity, thermal behavior, thermo gravimetric analysis (TG/DTG), mechanical strength in compression and flexural, apparent density, water absorption in percentile, and the samples morphology was analyzed in a MEV. The density and humidity percentage of the sisal fiber were also determined. The thermal conductivity of the composites was higher than the pure polyurethane foam, the addition of nonwoven sisal fibers will become in a higher level of compact foam, reducing empty spaces (cells) of polyurethane, inducing an increase in k value. The apparent density of the composites was higher than pure polyurethane foam. In the results of water absorption tests, was seen a higher absorption percent of the composites, what is related to the presence of sisal fibers which are hygroscopic. From TG/DTG results, with the addition of sisal fibers reduced the strength to thermal degradation of the composites, a higher loss of mass was observed in the temperature band between 200 and 340 °C, related to urethane bonds decomposition and cellulose degradation and its derivatives. About mechanical behavior in compression and flexural, composites presented a better mechanical behavior than the rigid polyurethane foam. An increase in the amount of sisal fibers induces a higher rigidity of the composites. At the thermal behavior tests, the composites were more mechanically and thermally resistant than some materials commonly used for thermal insulation, they present the same or better results. The density of nonwoven sisal fiber had influence over the insulation grade; this means that, an increaser in sisal fiber density helped to retain the heat

Caracterização morfológica e microestrutural da perovskita BaCexPr1-xO3 sintetizada a partir do método de complexação combinando EDTA/Citrato

In this study, binary perovskite (BaCexO3) were doped with praseodymium (Pr) to obtainment of the ternary material BaCexPr1-xO3. This material was synthesized by the complexation method combining EDTA/Citrate with the stoichiometric ratio of the element Praseodymium ranging from x = 0.1 to x = 0.9 in order to determine the influence of this rare earth element on the morphology and microstructure of the final powder. At first the material was synthesized based on the route proposed by literature (Santos, 2010), and then characterized by SEM and XRD, besides being refined by the Rietveld method. In the material that had lowest residual parameter, S, and lowest average size of crystal, pH variation of synthesis solution was made in order to identify the influence of this parameter on the morphology and microscopy of the final powder. The results show that addition of praseodymium did not directly influence the crystallographic and lattice parameters, keeping even the same orthorhombic structure of the binary material BaCexO3, according to Yamanaka et al (2003). Material type BaCe0,2Pr0,8O3 had lowest residual parameter (S=1.4) and lowest average size of crystallite (26.4 nm), being used as reference in the pH variation of synthesis solution for 9, 7, 5 and 3, respectively. Variation of this parameter showed that when the synthesis solution pH was decreased to below 11, there was an increase in the average size of crystals, for pH 9, about 58.3%, for pH 7 (30.3 %), for pH 2 (2.3%) and for pH 3 (42%), indicating that the value initially used and quoted by Santos (2010) was the most coherent

Relação entre habilidades auditivas e fonológicas em crianças com dislexia do desenvolvimento

A dislexia do desenvolvimento, dificuldade específica de leitura, é caracterizada pela dificuldade em realizar a decodificação fono-grafêmica e percepção de fonemas acusticamente semelhantes. Este estudo teve como objetivo caracterizar o desempenho de crianças com dislexia quanto às habilidades auditivas e de consciência fonológica, correlacionando-as. Participaram deste estudo crianças com dislexia e com bom desempenho escolar, submetidas a avaliações audiológica, do processamento auditivo e das habilidades fonológicas. Os resultados indicaram diferença estatisticamente significante entre as habilidades auditivas de seqüência para sons verbais, mensagem competitiva ipsi e contra-lateral, dicótico de dígitos e dissílabos alternados e ainda nos subtestes de síntese, segmentação, manipulação e transposição. Os achados deste estudo evidenciaram correlação entre provas de memória auditiva e manipulação silábica e fonêmica e associação entre habilidades auditivas e fonológicas, sugerindo que os processos auditivos interferem diretamente na percepção de aspectos acústicos, temporais e seqüenciais dos sons para formação de uma representação fonológica estável.

CONCLUSÃO: o estudo concluiu que escolares com dislexia do desenvolvimento apresentam dificuldades quanto à identificação de rima e produção de palavras com o som dado, apontando para um déficit em acessar os códigos e as representações fonológicas.

O turismo de base local como um possível indutor de desenvolvimento rural: uma análise da realidade e das potencialidades no distrito de dondo-moçambique

The current debate on rural development focuses on the territorial approach, recognizing the multifunctional character of rural areas. Emphasize the use of endogenous forces, the need of implement policies which valorize local specificities, the participation of social actors in revitalization of rural areas. In this context tourism enters as a means to induce a new dynamic to rural areas, since the activity is regarded as a channel for the upgrading of the natural and cultural resources and the rural way of life. This study focuses on local-based tourism as a promoter of rural development, giving an analysis of the social reality and potential for this tourism in the district of Dondo. In it, is proposed to analyze the potential for development of local-based tourism in the district of Dondo, assessing the extent to which local reality enables the inclusion of the community in the management of local tourism resources. For this, was showed the inclusion of local-based tourism in the current context of rural development, was identified and organized systematically the factors that influence the implementation of local-based tourism in the study area and was verified as far as possible the study area corresponds to the constraints identified, showing how local-based tourism can best been encouraged. Was adopted a qualitative methodological approach to both the procedures and data processing, but also by critical approach, using bibliographical research, semi-structured interviews that fell on the group of public administrators who work in tourism and community leaders. The critical analysis was based on the principles of sustainability o Sachs particular ecological, social, cultural, economic, space, beyond the analysis of political and institutional aspects. The survey results show that the district of Dondo has a potential for implementing a model of tourism development on a local basis, since it is rich in natural and cultural research, benefits from good network accessibility in the context of the market in the region, the population live according to their habits and customs and value their identity. There is also a good cooperation between community members, although not in tourism, a fact which is observed through the lever of community participation in associations, cooperatives, working in areas such as agriculture, fishing, environment, civic education etc. It also has public funding sources to augment or stimulate local investment. Despite obstacles such as inexistence of policies and local plans for tourism development, lack of awareness of tourism, lack of basic infrastructure, as well as equipment and facilities to support tourism, the results shows that these problems can be solved through a public commitment from both government, and community through a joint planning and participation

Caracterização morfológica e sedimentologica da plataforma, continental brasileira adjacente aos municípios de Fortim, Aracati e Icapuí- CE

The study area is located on the Brazilian Continental Shelf adjacent to Ceará State, inserted in the submerged Potiguar Basin. This area was submitted to extensional efforts during Upper Cretaceous, associated to the begining of the rifting that resulted in African and South American Continent separation. The main goal of this research was to better understand the sedimentary and geomorphological characteristics of the continental shelf adjacent to Fortim, Aracati and Icapuí (Ceará State). The used data base included geophysical (sides scan sonar and bathymetry studies) and sedimentological survey, associated to satellite image processing and interpretation. Inferences about suspended material and longshore drift was possible using satellite images, and differente bedforms were characterized such as: different kinds of dunes (longitudinal, cross and oblique), bioclastic banks, paleochannels, flat and rock bottom. The researched area comprehended about 2509,13 km2, where 6 different sedimentary facies, based on sediment composition and texture, could be recognized, such as: Bioclastic Sand, Siliciclastic Sand, Biosiliciclastic Sand, Bioclastic gravel, Biosiliciclastic sand with granule and gravel, and Silicibioclastic sand with granule and gravel. The integration of bathymetric, satellite image, side scan sonar and sedimentological data allow us a better characterization of this continental shelf area, as to advance in the knowledge of the continental shelf of the state of Ceara, a very important area to the oil industry because of its potential exploration and e exploitation, and to environmental survey as well

A liga como recebido, exibe a seguinte morfologia: pites hemisféricos> região de transição A> região de transição B> irregulares> cônicos. A quantidade de pites na liga tratada a cada tempo de exposição é: região de transição B> hemisféricos> região de transição A> cônicos> irregulares.

Caracterização morfológica do útero e tubas uterinas de fetos bovinos da raça Nelore (Bos primigenius indicus) em diferentes fases de gestação

Para a realização desta pesquisa, foram coletados vinte fetos fêmeas em diferentes fases de gestação da raça Nelore. Os cornos uterinos e as tubas uterinas foram dissecados, mensurados e os fragmentos fixados em paraformaldeído tamponado a 4,00%, processados e incluídos em paraplástico. Os cortes com 5 mm foram corados com hematoxilina e eosina, tricrômio de Masson (para fibras colágenas), Verhoeff (para fibras elásticas) e com reticulina (para fibras reticulares). Os resultados mostraram que não há diferença significativa das mensurações entre os lados direito e esquerdo para os cornos uterinos e tubas uterinas, porém há correlação entre os valores obtidos das mensurações dos órgãos em função da idade dos fetos, ou seja, o crescimento dos órgãos acompanha o crescimento fetal. O epitélio de revestimento do útero não apresenta variações morfológicas evidentes no período analisado. A partir de 23 semanas de gestação, a mucosa uterina apresenta evolução marcante no desenvolvimento das projeções e não há aparecimento de glândulas endometriais na parede uterina no período analisado. A camada muscular apresenta a subcamada circular interna desenvolvida até 23 semanas de gestação e a partir de 24 semanas há presença das duas subcamadas. A camada serosa é típica e não mostra variabilidade no decorrer da gestação. As tubas uterinas apresentam diferenças de crescimento, principalmente dos pregueamentos que a partir de 23 semanas de gestação tornaram-se mais altos e ramificados, porém sem aparecimento de pregas terciárias. Com o desenvolvimento fetal, os cílios epiteliais do pregueamento tubárico são maiores em tamanho e em número. Até 32 semanas de gestação, a camada muscular das tubas uterinas apresenta apenas a subcamada circular interna. A camada serosa e o mesosalpinge são típicos e não apresentam variações importantes. As variações mais marcantes para os órgãos estudados ocorreram a partir de 23 semanas de gestação.
