Latin-American Society of Forensic Genetics (SLAGF) Interlaboratory Quality Control Exercise (2010-2011) included the analysis of three bloodstain samples in FTA Classic Card (three persons, biologically unrelated) and one theoretical exercise. There were 56 participating laboratories from 13 Latin-American countries that belong to society, were reported 70 STRs, including autosomal and sex chromosome markers with consensus in 53 STRs with a rate in reporting errors of 2.3%. Fifty-six laboratories reported results in theoretical exercise with mistakes in calculation of IP for each marker. It is necessary to hold meetings to discuss the results of this exercise to reach conclusions and recommendations on all aspects of DNA forensics analysis and paternity test, to improve results and quality in the results of each laboratory. © 2011 Elsevier B.V.

No presente artigo, conforme o entendimento de que modelos te- óricos subsidiam a compreensão de fenômenos investigativos, objetivou-se elucidar os conceitos da teoria sociológica de Norbert Elias, considerando-se que esta é uma excelente fonte de análise para se compreender o universo do ser professor, apesar de o autor não abordar diretamente questões relacionadas ao campo da educação. A partir do conceito de configuração, é possível dizer que a constituição do ser professor resulta das diferentes configurações nas quais ele está imerso, pois, de acordo com Elias, as pessoas (professores, pais, gestores, ministros, alunos etc.) modelam suas ideias a partir de todas as suas experiências e, essencialmente, das experiências vividas no interior do próprio grupo. É observável que as configurações, formadas por grupos interdependentes de pessoas, e não por indivíduos singulares, apresentam-se cada vez mais ampliadas nos contextos escolares, com funções especializadas e específicas (professores, alunos, diretores, coordenadores, supervisores, secretários etc.), em grupos que se tornam cada vez mais funcionalmente dependentes. As cadeias de interdependência estão mais diferenciadas e, consequentemente, mais opacas e dificilmente controláveis por parte de quaisquer grupos ou indiví- duos. Portanto, uma melhor compreensão será possível quando se estudar empiricamente as configurações que estão em jogo na educação brasileira. Daí se justifica a análise das configurações e das teias de interdependência em que os professores estão envolvidos. Enfim, a aplicação dos modelos de competição abordados por Elias possibilita evidenciar as problemáticas sociológicas do ser professor, tornando-as mais evidentes e facilitando o entendimento do jogo para reorganizá-lo em termos de equilíbrio na teia social.

Introduction: Studies on education in health are important for the concretion of action of promotion of the health. Objective: To verify the changes of theoretical knowledge on sitting posture, evaluated at two moments (initial and final,) considering two programs of education (expositive lesson and operative groups). Methods: 75 pupils had been citizens, of both the sexes, three 4as series of a public school, evaluated previously (A1) on seated position; group 1 was submitted to a procedure of expositive education, the 2 educative games in the 2 and, the 3 to no intervention. After one week they had been reevaluated (A2). For the moments the test of Wilcoxon was applied and between the Kruskal groups Wallis. Results: In the comparison inside of the groups, of 2 and 3 they had presented increase in the number of rightness on position seated in the after-test, with statistical significant difference, whereas in the group has controlled, such fact did not occur. In the comparison between groups, at the first moment (A1), 2 groups e 3 had not presented significant difference statistical (p > 0,05), however, in as moment notices that it had difference statistics between the three groups (p < 0,01), being that the G3 presented minor frequency of errors (md = 5) in relation to the g2 (md = 8) and g1 (md = 10). Conclusions: It can be affirmed that educative techniques that supply information and promote debates and exchanges of experiences between the participants increase the possibilities of incorporation of the contents related to the sitting posture.

Four different assays (the Folin-Ciocalteu, DPPH, enzymatic method, and inhibitory activity on lipid peroxidation) based on radically different physicochemical principles and normally used to determine the antioxidant activity of food have been confronted and utilized to investigate the antioxidant activity of fruits originated from Brazil, with particular attention to more exotic and less-studied species (jurubeba, Solanum paniculatum; pequi, Caryocar brasiliense; pitaya, Hylocereus undatus; siriguela, Spondias purpurea; umbu, Spondias tuberosa) in order to (i) verify the correlations between results obtained by the different assays, with the final purpose to obtain more reliable results avoiding possible measuring-method linked mistakes and (ii) individuate the more active fruit species. As expected, the different methods give different responses, depending on the specific assay reaction. Anyhow all results indicate high antioxidant properties for siriguela and jurubeba and poor values for pitaya, umbu, and pequi. Considering that no marked difference of ascorbic acid content has been detected among the different fruits, experimental data suggest that antioxidant activities of the investigated Brazilian fruits are poorly correlated with this molecule, principally depending on their total polyphenolic content. © 2013 Elena Gregoris et al.
