Abstract: the article's purpose is to reveal the discourse enunciated by the workers of the comupra - community counsel united pro ribeiro de abreu, a ngo from belo horizonte, about the positive (pleasure) or negative (suffering) meaning they attribute to their work. besides being a factor of illness and health, the work is central in individual and social lives and it is one of the fields of study presently in expansion. yet, in the ngos from the third sector, it is still not much studied. semi-structured interviews were the main knowledge collection tool. the obtained information was treated by means of discourse analysis. six workers from the comupra were interviewed. the analyses revealed that the positive meaning of the work surpass the negative meaning. the situations in which pleasure occurs are taken as more important than those provoking suffering, showing that the choice for working in the third sector is associated to an expectation of individual and community changes.

Abstract: experiments with animals are very important for the improvement of science. the use of mice in experiments is due to their similarity with humans, the easy of raising and maintaining them and their very fast response. these animals have the same desaturase and elongase enzymes as humans and so they are used in research involving the incorporation and synthesis of fatty acids in tissues. the fatty acids omega-3 and omega-6 are extremely important in the human diet because they are not synthesized de novo and are precursors of very long-chain polyunsaturated fatty acids, such as the eicosapentaenoic, docosahexaenoic and arachidonic acids. these acids play important roles in animals, such as precursors of eicosanoids, which are directly involved in the immune system and inflammatory response. the dietary n-3:n-6 intake ratio is important for assessing proper fatty acid intake and for preventing the development of diseases. thus, this article assessed the incorporation of fatty acids in animal tissues and discussed the importance of n-3 fatty acids and its metabolites for the immune system.

Revista Eletr?nica de Sistemas de Informa??o , 2008,
Abstract: A eficiência de mercado é muito questionada por especialistas, alguns trabalhos sugerem oportunidades de arbitragem em diversas opera es financeiras. Essas oportunidades podem ser explicadas principalmente pela assimetria de informa o, pois a forma o de pre os no mercado acionário está diretamente ligada as informa es, portanto o investidor que as possuir com mais rapidez, possui uma vantagem competitiva. O objetivo desse artigo é verificar a existência de oportunidades de arbitragem utilizando os Recibos de A es nos Estados Unidos (ADRs –American Depositary Receipts), negociadas no mercado americano, e suas respectivas a es, negociadas no mercado nacional. Através do estudo de caso realizado com quatro empresas, desconsiderando os custos de transi o, foram encontradas janelas de oportunidades para arbitragem. Dentre as empresas estudadas, duas apresentaram oportunidades freqüentes de arbitragem, sendo que uma delas a oportunidade de arbitragem pode ser modelada por modelo de série temporal.
IDENTIFICA O AUTOMáTICA DAS ORDENS DOS MODELOS GARCH UTILIZANDO REDES NEURAIS
André Machado Caldeira,Reinaldo Castro Souza,Maria Augusta Soares Machado
Engevista , 2009,
Abstract: GARCH models are being largely used to model the volatility of financial assets, and GARCH (1,1) is the one mostly used. The identification of the model specification has not been fully explored. However, technology of specialist systems has been used in some applications of time series model as, for example, in time series classification problems (Reynolds et al, 1995) and ARMA models identification (Machado, 2000). The aim of this paper is to propose an intelligent system that can correctly identify the specification of GARCH models providing the right choose of the model to be used, avoiding the indiscriminate usage of GARCH (1,1) model.

Abstract: Norovirus (NoV), sapovirus (SaV) and human astrovirus (HAstV) are viral pathogens that are associated with outbreaks and sporadic cases of gastroenteritis. However, little is known about the occurrence of these pathogens in relatively isolated communities, such as the remnants of African-descendant villages (“Quilombola”). The objective of this study was the frequency determination of these viruses in children under 10 years, with and without gastroenteritis, from a “Quilombola” Community, Northern Brazil. A total of 159 stool samples were obtained from April/2008 to July/2010 and tested by an enzyme immunoassay (EIA) and reverse transcription-polymerase chain reaction (RT-PCR) to detect NoV, SaV and HAstV, and further molecular characterization was performed. These viruses were detected only in the diarrheic group. NoV was the most frequent viral agent detected (19.7%-16/81), followed by SaV (2.5%-2/81) and HAstV (1.2%-1/81). Of the 16 NoV-positive samples, 14 were sequenced with primers targeting the B region of the polymerase (ORF1) and the D region of the capsid (ORF2). The results showed a broad genetic diversity of NoV, with 12 strains being classified as GII-4 (5–41.7%), GII-6 (3–25%), GII-7 (2–16.7%), GII-17 (1–8.3%) and GI-2 (1–8.3%), as based on the polymerase region; 12 samples were classified, based on the capsid region, as GII-4 (6–50%, being 3–2006b variant and 3–2010 variant), GII-6 (3–25%), GII-17 (2–16.7%) and GII-20 (1–8.3%). One NoV-strain showed dual genotype specificity, based on the polymerase and capsid region (GII-7/GII-20). This study provides, for the first time, epidemiological and molecular information on the circulation of NoV, SaV and HAstV in African-descendant communities in Northern Brazil and identifies NoV genotypes that were different from those detected previously in studies conducted in the urban area of Belém. It remains to be determined why a broader NoV diversity was observed in such a semi-isolated community.

Abstract: several studies have demonstrated that regular physical activity improves diabetes conditions, favoring the peripheral glucose uptake, glycogen and protein metabolism. however, the effects of high intensity physical training on the immune system of diabetic organisms are not totally clear. the aim of this study was to verify the effects of high intensity physical training on the total and differential leukocyte count of diabetic rats. male young wistar rats were distributed into four groups: sedentary control (sc), trained control (tc), sedentary diabetic (sd) and trained diabetic (td). diabetes was induced by alloxan (30 mg/kg body weight i.v.). during six weeks the animals of tc and td groups followed a high intensity physical training protocol which consisted of four sets of 10 jumps/day (interrupted by one minute of rest interval) in a swimming pool, with the water level corresponding to 150% of the body length and overload equivalent to 50% of the body weight. at the end of the experimental period, blood samples were collected for total and differential leukocyte count. the results were analyzed by anova at a significance level of 5%. serum glucose was increased in diabetic groups while the insulin level was reduced in these groups. there were no significant differences in lymphocytes, neutrophils, and eosinophils, and in total leukocyte count when the groups were compared. monocytes count was higher in both trained groups (sc = 10.0 ± 4.5, tc* = 25.4 ± 7.9, sd = 19.75 ± 7.4, td* = 25.8 ± 4.4%). the relative weight of the thymus was reduced by diabetes and training (sc = 125.0 ± 37.7, tc* =74.6 ± 8.2, sd* = 47.5 ± 12.2, td* = 40.1 ± 16.9). in conclusion, the high intensity physical training protocol did not change the general diabetes conditions, but improved relative monocytes. these results can represent a positive effect on the immune response.

Revista Brasileira de Medicina do Esporte , 2002,
Abstract: Estudos têm demonstrado que o exercício físico regular melhora as condi es do diabetes, facilitando a capta o periférica da glicose e o metabolismo de glicogênio, proteínas, etc. Por outro lado, pouco se conhece sobre os efeitos do exercício intenso em diabéticos, principalmente com rela o ao sistema imune desses organismos. O presente estudo teve como objetivo verificar os efeitos de um treinamento físico de alta intensidade sobre a contagem total e diferencial de leucócitos em ratos diabéticos. Ratos machos jovens Wistar foram distribuídos em quatro grupos: controle sedentário (CS), controle treinado (CT), diabético sedentário (DS) e diabético treinado (DT). O diabetes foi induzido por aloxana (35mg/kg de peso corporal). Durante seis semanas os animais dos grupos CT e DT realizaram um protocolo de treinamento físico, que consistiu na realiza o de quatro séries de 10 saltos (intercaladas por um minuto de intervalo) em piscina, com o nível da água correspondendo a 150% do comprimento corporal e sobrecarga equivalente a 50% da massa corporal dos animais. Ao final do período experimental, amostras de sangue foram coletadas para a contagem total e diferencial dos leucócitos. Os resultados foram avaliados estatisticamente por ANOVA com um nível de significancia de 5%. A glicemia foi aumentada entre os diabéticos e a insulinemia diminuída. N o foram observadas diferen as significativas na contagem diferencial dos linfócitos, neutrófilos, eosinófilos e contagem total de leucócitos entre os grupos estudados. Houve aumento dos monócitos entre os treinados (CS = 10,0 ± 4,5, CT* = 25,4 ± 7,9, DS = 19,75 ± 7,4, DT* = 25,8 ± 4,4%). O peso relativo do timo foi reduzido pelo treinamento e pelo diabetes (CS = 125,0 ± 37,7, CT* = 74,6 ± 8,2, DS* = 47,5 ± 12,2, DT* = 40,1 ± 16,9mg/100g). Esses resultados permitem concluir que o treinamento físico de alta intensidade n o alterou o estado geral do diabetes, mas aumentou os monócitos, o que pode representar um efeito positivo sobre a resposta imunológica desses animais.

Creative Education (CE) , 2017, DOI: 10.4236/ce.2017.86068
Abstract: The evaluation of learning has been the subject intriguing, full of stigmas historically constructed. Sometimes (most) is seen as instrument of punishment, coercion, discipline. The nature is classified as descriptive exploratory approach with mixed quantitative and qualitative. To collect data, questionnaires were given to students and teachers from 1st to 4th year course and consultation with the instruments of Student Performance Evaluation (AD). Treatment of qualitative data was by content analysis. It was observed that there are similarities between the objectified and practice, teachers and students recognize the systematic evaluation used as a component in the construction of knowledge, however, is not fully understood the operationalization process of this design evaluation by the subjects involved in research, because existence of distortions in its implementation by students and teachers compromising the pedagogical dimension of assessment, for example the “standardization” of the considerations made in relation to student performance. These factors credibility in AD by students showed decline throughout the course. However the traditional evaluation culture is still present in moments of assessment because the talks are still noticeable feeling of fear of exposing opinions. It was therefore concluded that no action needs to AD in practice between in accordance with the theory, for example, with skills that motivate teachers to the correct implementation of the proposal. It is also necessary to make the student realize the process as responsible for the results in individual and collective performances of AD.
