Forma??o continuada de professores em informática na Educa??o Especial: análise de disserta??es e teses
Orth, Miguel Alfredo;Mangan, Patrícia Kayser Vargas;Sarmento, Dirléia Fanfa;
Revista Brasileira de Educa??o Especial , 2011, DOI: 10.1590/S1413-65382011000300010
Abstract: this study aimed to map studies done in the sphere of brazilian theses and dissertations that focus on computer sciences in special education. this paper is one of the results of an earlier study on the evaluation of further education and distance education courses for teachers of basic education in brazil. using the davies' systematic review method, we mapped brazilian theses and dissertations available on the capes' repository of theses published between 1990 and 2009 and that related to this issue. we carried out fluctuating reading of abstracts, titles, and keywords, which enabled us to select 34 dissertations and three theses, grouped and discussed in four major categories. other analyses and categorizations enabled us to identify some of the major concerns of brazilian researchers during this period; they also lead us to infer that the increase in studies on this theme is negligible. we were able to detect that there are few studies related to further education (8 dissertations) and to the didactical use of computer resources in education (6 dissertations), both of which are essential for enabling inclusion of diversity of special needs.

Abstract: studies indicate that the presence of physical chronic disease in childhood may constitute an important factor to the quality of mother-child interaction. however, few studies investigate the childrearing practices in children with physical chronic disease. the daily care demand by the disease treatment as well as the child physical and emotional fragility may affect the childrearing practices. fourty mothers participated in this study, half of them with a child with physical chronic disease and the other with a child without this condition. the children were of both sexes, 3 to 4 years old. the participants were selected in public hospitals and schools. a semi-structured interview was used to investigate the mother's childrearing practices, examined by content analysis. the results show a marginally significant difference showing that the group of mothers of the chronic disease children uses coercive practices less frequently. moreover, there was a significant difference between the groups in relation to the use of physical punishment and privation/penalty, suggesting that mothers of chronic disease children use less frequently this type of practice. the results support the initial hypothesis that mothers of chronic disease children would be less coercive when compared to mothers of the other group.
Valor nutritivo do feno de braquiária amonizado com uréia ou inoculado com Pleurotus ostreatus

Abstract: the effect of a chemical treatment (ammoniation with urea) or a biological treatment (innoculation with the fungus pleurotus ostreatus) on the nutritive value of brachiaria decumbens hay was evaluated by means of chemical analyses and a digestibility trial with sheep. both treatments lasted 42 days, and thereafter the hay was dried and ground for animal feeding. the experimental diets were the following: untreated brachiaria hay (fnt); untreated hay plus urea added in the trough (fnt+u); fungus-treated hay plus urea (ftb+u); and ammoniated hay plus untreated hay (ftq+fnt). the fnt+u, ftb+u and ftq+fnt diets were isonitrogenous. both the chemical and biological treatments caused changes in hay chemical composition. ammoniation raised crude protein (cp) and acid detergent fiber (adf) contents and reduced both hemicellulose(hem) content and the proportion of hemicelullose in cell walls (hem-ndf). the biological treatment tended to raise cp; it increased adf, lignin (lig), cellulose proportion in cell walls (cel-fdn) and lignin proportion in cell walls (lig-fdn); it reduced neutral detergent fiber (ndf), hem and hem-ndf. however, it reduced dry matter (dm), ndf, cellulose (cel) and fda digestibility; however, it increased intake, probably due to smaller ndf content and smaller particle size, causing a higher rate of passage. both the biological and chemical treatments are important alternatives in increasing the nutritive value of lignocellulosic materials. nevertheless, the results obtained in this experiment were not satisfactory.

Abstract: the problem of minimising the technical energy losses in electric power distribution systems corresponds to the definition of the best network configuration, through the manipulation of sectionalising switches. using a graph terminology, we have a combinatorial optimisation problem, whose solution asks for the definition of the minimum spanning tree for the network. with the purpose of treating the case of time-varying profiles of energy requirements, this paper presents the first results obtained with the application of learning classifier systems, an evolutionary computation approach to find network configurations close to the one associated with minimum energy losses. its uttermost feature is the possibility of application to on-line network supervision, proposing new configurations that will reduce the level of energy losses when significant demand variations are detected.

Abstract: O consumo de doce de leite caseiro, vendido em feiras livres, é comum no Estado do Rio Grande do Sul. Geralmente, estes produtos n o s o fabricados em acordo com as boas normas de fabrica o e podem constituir perigo à saúde do consumidor. O objetivo do presente estudo foi analisar, microbiologicamente, amostras de doce de leitecomercializado nas feiras livres da cidade de Pelotas, Estado do Rio Grande do Sul, conforme legisla o em vigor da Agência Nacional de Vigilancia Sanitária – Anvisa, e, dessa forma, verificar as condi es sanitárias do produto em quest o. Foram adquiridas, aleatoriamente, amostras de doce de leite de feiras livres existentes na cidade de Pelotas, Estado do Rio Grande do Sul, Brasil. Das 12 feiras cadastradas na prefeitura de Pelotas, em apenas cinco foram encontradas amostras de doce de leite. As análises microbiológicasforam realizadas conforme metodologias preconizadas pela Resolu o RDC n° 12 de 2 de janeiro de 2001 da Agência Nacional de Vigilancia Sanitária – Anvisa. Com base nas metodologias empregadas, n o se obteve isolamento de microrganismos patogênicos nas amostras de doce de leite pesquisadas. De acordo com os critérios estabelecidos pelodocumento RDC no 12 da Anvisa, concluiu-se que nenhuma das amostras de doce de leite revelou contamina o bacteriana patogênica. The consumption of homemade doce de leite, which is sold in street markets, is very common in the state of Rio Grande do Sul, Brazil. Generally, these products are not manufactured according to good hygiene guidelines, and may be a risk to consumers’ health. The aim of the present study was to analyze microbiologically samples of doce de leite commercialized in street markets in the city of Pelotas, Rio Grande do Sul State, according to the present legislation of Brazil’s National Health Surveillance Agency (Anvisa), and thus verify the sanitary conditions of this product. Samples of doce de leite were randomly acquired from street markets in Pelotas, Rio Grandedo Sul State, Brazil. Among the 12 street markets registered in the Pelotas City Council, doce de leite samples were found in only five. The microbiological analyses were carried out according to document RDC n° 12 (Jan. 12, 2001) from Brazil’s National HealthSurveillance Agency (Anvisa). Based on the methodologies employed, no microbial pathogen isolates were detected in the investigated samples of doce de leite. According to the criteria established by document RDC n° 12, it was concluded that none of the doce de leite samples revealed pathogenic bacterial contamination.
