As diferentes concepções de corpo ao longo da história e nos dias atuais e a influência da mídia nos modelos de corpo de hoje

Sabe-se até hoje, que falar sobre o corpo não é só tratar de matéria. O corpo tem uma importância bastante grande e interessante dentro do contexto social e filosófico. Sócrates, Platão, Descartes são exemplos de filósofos que tentavam compreender o corpo de alguma forma. Desde a Grécia Antiga, o corpo é encarado como um santuário. Os Jogos Olímpicos representavam essa visão, com toda a beleza de corpos atléticos e vigorosos. Ficava clara a concepção de que um corpo bonito e saudável era sinônimo de beleza e virilidade. Mas nem sempre isso foi assim. Na Idade Média, corpos bonitos eram aqueles que, esteticamente falando, não pareciam tão atraentes assim. Ser gordo nessa época representava saúde. Para as mulheres, ser gorda significava ser uma boa reprodutora e mãe de filhos saudáveis. Além disso, a Igreja exercia forte influência nessa época, chegando até a extinguir os Jogos Olímpicos. Qualquer culto ao corpo era estritamente proibido. Até chegarmos aos dias de hoje, o corpo passou por diversas modificações. O que se vê hoje, são corpos construídos, seja pela mídia ou por cirurgias plásticas. A concepção de corpo da sociedade contemporânea é puramente artificial.

Dilema moral na Educação Infantil: generosidade ou justiça?

The aim of this study is to investigate the judgments about the virtue of generosity or justice by teachers in early childhood education and compare their judgments with the children’s judgments about generosity or justice. We interviewed 26 teachers and 90 children aged 4, 5 and 6 years at this level of education. The instrument used was a moral dilemma in which the protagonist of the story would have to choose between giving a prize to the child who drew the most beautiful picture (justice) or to the child who was sad (generosity). The results indicate that justice is the virtue most valued by teachers and that it is already valued by children and may be a need for them. And generosity is valued more by children than by teachers.

Avaliação de um sensor de resistencia eletrica e sua correlação com atributos do solo

The electrical measures of the soil have been used as variables that correlate with its characteristics. This study aimed at developing an electrical capacitance sensor of low cost, to evaluate its performance on the field and verify the correlation between the measurements of electrical capacitance with physical properties (sand, silt and clay) and chemical properties of soil (pH, MO, P resin, H + Al, K, Ca, Mg, SB, CTC and V%) and the moisture content. The data sampling was performed at the farm named "Capão da Onça" which belongs to the State University of Ponta Grossa. The samples collection was conducted in an area of approximately 13 hectares, totalizing 81 samples. In each sampling the electrical capacitance of the soil was measured. After the sensor withdrawal, soil samples were collected and sent to be analysed in the laboratory of the College of Agronomics Science of the Paulista State University. The measuring instrument used to collect data on electric capacitance of the soil a digital multimeter was used. The data were submitted to the analysis of correlation and regression. The developed system presented a low cost and it was capable to measuring variation of the electrical capacitance of the soil. The obtained measures satisfactorily correlated with the levels of clay and sand, and weakly with the moisture content. This had demonstrated the possibility to use a sensor to verify the soil texture in not homogeneous areas. The measures of the electrical capacitance of the soil obtained by the sensor had significantly correlated with the soil attributes: calcium, magnesium, pH, SB and CTC. These results had demonstrated the possibility to use a sensor for soil fertility control.

Description of the female and new records of Triatoma baratai Carcavallo & Jurberg, 2000 (Hemiptera: Heteroptera: Reduviidae: Triatominae) from Mato Grosso do Sul, Brazil, with a key to the species of the Triatoma matogrossensis subcomplex

Triatoma baratai Carcavallo & Jurberg, 2000, a species similar to Triatoma williami Galvao, Souza & Lima, 1967 and belonging to the T. matogrossensis subcomplex, was described based on a male specimen collected in a sylvatic environment, near a cave, in Bonito county, Bodoquena mountain range, state of Mato Grosso do Sul, Brazil. In the present work we describe the female of T. baratai, captured in a chicken house, in Nioaque county, state of Mato Grosso do Sul, Brazil. Furthermore, we recorded the occurrence of T. baratai in domiciles and peridomestic environment in another four municipalities (Bodoquena, Bela Vista, Corumba, and Miranda), extending its geographical distribution. Finally, we present a key to the species of the Triatoma matogrossensis subcomplex.

Magnetic Barkhausen emission in lightly deformed AISI 1070 steel

The Magnetic Barkhausen Noise (MBN) technique can evaluate both micro- and macro-residual stresses, and provides indication about the relevance of contribution of these different stress components. MBN measurements were performed in AISI 1070 steel sheet samples, where different strains were applied. The Barkhausen emission is also analyzed when two different sheets, deformed and non-deformed, are evaluated together. This study is useful to understand the effect of a deformed region near the surface on MBN. The low permeability of the deformed region affects MBN, and if the deformed region is below the surface the magnetic Barkhausen signal increases. (C) 2011 Elsevier B.V. All rights reserved.

Polyphyly of the hawk genera Leucopternis and Buteogallus (Aves, Accipitridae): multiple habitat shifts during the Neotropical buteonine diversification

Abstract Background The family Accipitridae (hawks, eagles and Old World vultures) represents a large radiation of predatory birds with an almost global distribution, although most species of this family occur in the Neotropics. Despite great morphological and ecological diversity, the evolutionary relationships in the family have been poorly explored at all taxonomic levels. Using sequences from four mitochondrial genes (12S, ATP8, ATP6, and ND6), we reconstructed the phylogeny of the Neotropical forest hawk genus Leucopternis and most of the allied genera of Neotropical buteonines. Our goals were to infer the evolutionary relationships among species of Leucopternis, estimate their relationships to other buteonine genera, evaluate the phylogenetic significance of the white and black plumage patterns common to most Leucopternis species, and assess general patterns of diversification of the group with respect to species' affiliations with Neotropical regions and habitats. Results Our molecular phylogeny for the genus Leucopternis and its allies disagrees sharply with traditional taxonomic arrangements for the group, and we present new hypotheses of relationships for a number of species. The mtDNA phylogenetic trees derived from analysis of the combined data posit a polyphyletic relationship among species of Leucopternis, Buteogallus and Buteo. Three highly supported clades containing Leucopternis species were recovered in our phylogenetic reconstructions. The first clade consisted of the sister pairs L. lacernulatus and Buteogallus meridionalis, and Buteogallus urubitinga and Harpyhaliaetus coronatus, in addition to L. schistaceus and L. plumbeus. The second clade included the sister pair Leucopternis albicollis and L. occidentalis as well as L. polionotus. The third lineage comprised the sister pair L. melanops and L. kuhli, in addition to L. semiplumbeus and Buteo buteo. According to our results, the white and black plumage patterns have evolved at least twice in the group. Furthermore, species found to the east and west of the Andes (cis-Andean and trans-Andean, respectively) are not reciprocally monophyletic, nor are forest and non-forest species. Conclusion The polyphyly of Leucopternis, Buteogallus and Buteo establishes a lack of concordance of current Accipitridae taxonomy with the mtDNA phylogeny for the group, and points to the need for further phylogenetic analysis at all taxonomic levels in the family as also suggested by other recent analyses. Habitat shifts, as well as cis- and trans-Andean disjunctions, took place more than once during buteonine diversification in the Neotropical region. Overemphasis of the black and white plumage patterns has led to questionable conclusions regarding the relationships of Leucopternis species, and suggests more generally that plumage characters should be used with considerable caution in the taxonomic evaluation of the Accipitridae.

Necessidades em saúde segundo percepções de pessoas com tuberculose pulmonar

O presente estudo teve como objetivo conhecer as percepções sobre necessidades em saúde de pessoas com tuberculose pulmonar. Trata-se de estudo qualitativo, desenvolvido no distrito administrativo Capão Redondo, São Paulo. Os dados foram coletados em janeiro de 2010 por meio de entrevista semidiretiva. Foram entrevistadas onze pessoas em tratamento contra tuberculose, com idade mínima de 18 anos e sem limites de cognição. O material empírico foi decodificado a partir de técnica de análise de discurso. As percepções sobre necessidades em saúde estão relacionadas às dificuldades enfrentadas no processo saúde-doença, e o reconhecimento das necessidades em saúde mostrou-se condicionado à vigência do agravo à saúde. As necessidades identificadas decorrem de alterações biológicas, do cotidiano e de insuficiências no processo de produção dos serviços de saúde. A qualidade da assistência às pessoas com tuberculose está, entre outros fatores, condicionada à identificação e ao atendimento de suas necessidades em saúde.

Coinfecção de Tb/HIV em um distrito administrativo do município de São Paulo

OBJETIVO: caracterizar o perfil sóciodemográfico e epidemiológico de pessoas com co-infecção Tb/HIV, residentes no distrito administrativo Capão Redondo do Município de São Paulo no período de 2000 a 2009. MÉTODOS: Trata-se de um estudo retrospectivo. RESULTADOS: De um total de 1.612 casos de tuberculose, 162 casos foram positivos para o HIV. Houve predomínio da faixa etária de 30 a 39 anos (39,5%), sexo masculino (61,1%) e a forma pulmonar (68,5%). Apenas 47,5% dos casos evoluíram para a cura, 13% abandonaram o tratamento e 32,2% foram a óbito. RESULTADOS: Ressalta-se a necessidade do conhecimento da situação da co-infecção Tb/HIV no sentido de oferecer uma assistência adequada a esta clientela, considerando que ambas as enfermidades não podem ser discutidas isoladamente. CONCLUSÃO: Conclui-se que os casos de associação Tb/HIV contribuem para a não adesão ao tratamento e aumento da taxa de mortalidade.
