This article discusses non-daily concept formation in children talking about contributions from historical-cultural theory, highlighting school learning and teaching mediation as effective instruments on the development of these concepts. The goal is to reaffirm the understanding that it is by teaching activity that children acquire cultural concepts that are necessary to their humanization process. It also discusses the opposition established between psychogenic understanding on the formation of non-spontaneous concepts and the perspective in this historical-cultural theory, lines of development of daily concepts and not daily ones, and finally highlights the assumption that school educative practices are universal and necessary forms for this development.

This article makes a historiography discussion about slavery, indicates the advances in combats for an afro-brasilian history and, in view of cultural re-sense shows a need to consider the student’s prior knowledge and content of teaching History. These knowledges are essential to move beyond the denunciation of the violence of slavery and lead to the classroom buildings of the recent historiography on slavery in Brazil in view of breaking of stereotypes and changing attitudes.

This project aims to use concepts of innovation and obsolescence in products, to analyze and test the technological product FingerByte, a blend glove and joystick that needs to be appropriate for specific audiences. For this adjustment, this project uses a qualitative opinion survey, known as focus group in order to obtain data during product testing with certain audiences. Another purpose of the paper is to serve as a guide to readers in similar situations where you wish to use focus groups to develop products that have not been put on the market. The experiment uses the knowledge of public relations, both in research and in data analysis. The main results of the research are described in this monograph, in order to demonstrate what are the possible types of data being collected, helping the reader to approach the experience of qualitative research

Obesity is a growing problem all over the world, reaching all age groups and social categories. This is a concern ing fact, because the current life style, more and more sedentary, favors the develop of this disease. Children suffer with this ill more and more prematurely and many of its consequences will be carried during all their lives. With the intention of better understand the relationship between obesity and children's motor development, the present research investigated, through psychomotor evaluations of equilibrium and appendicular motor coordination, based on the Exame Neurológico Evolutivo (ENE), the existence of changes in the performance of this variables in obese children and children with normal weight, in their first year on fundamental education in a public state school. The static equilibrium presented itself lower than normal in obese, compared to the normal weight group. Statistically significant differences were not found in respect to dynamic equilibrium and appendicular motor coordination. With that, we can conclude that the static equilibrium suffered influence of obesity, because the centre of gravity might have been changed due to excessive weight

Após o infarto agudo do miocárdio (IAM), ocorrem alterações complexas na arquitetura ventricular, envolvendo tanto a região infartada como a não infartada. Nos últimos anos, estas adaptações, que podem ser identificadas na fase aguda do IAM, ou mais tardiamente, passaram a ser estudadas com o nome de remodelação ventricular (RV) pós-IAM 1 . O reconhecimento e entendimento deste processo é crítico, pois a RV pode estar associada a um pior prognóstico, pós-infarto, na dependência de diversos fatores. Outro aspecto relevante é que sua evolução pode ser modificada, por meio de diversas intervenções terapêuticas. Assim, abordaremos aspectos fisiopatológicos que envolvem a RV, bem como os efeitos das medicações comumente usadas no tratamento do infarto, nesse processo adaptativo.

We investigate in this work the behaviour of the decay to the fixed points, in particular along the bifurcations, for a family of one-dimensional logistic-like discrete mappings. We start with the logistic map focusing in the transcritical bifurcation. Next we investigate the convergence to the stationary state at the cubic map. At the end we generalise the procedure for a mapping of the logistic-like type. Near the fixed point, the dynamical variable varies slowly. This property allows us to approximate/rewrite the equation of differences, hence natural from discrete mappings, into an ordinary differential equation. We then solve such equation which furnishes the evolution towards the stationary state. Our numerical simulations confirm the theoretical results validating the above mentioned approximation

Em países de clima tropical, o calor é um dos principais limitantes à produção de frangos de corte, sendo ainda responsável por induzir uma elevada mortalidade, especialmente na fase de terminação. Visando aliviar o efeito do estresse pelo calor, foram avaliadas duas técnicas para melhorar a tolerância térmica: o condicionamento térmico precoce (TCP) e a formulação dieta utilizando o princípio de Mongin (equilíbrio eletrolítico). Para tanto, o balanço eletrolítico do K+Na-Cl foi ajustado em 350 mEq/kg e a relação eletrolítica (K+Cl)/Na em 3:1, pelo programa PPFR (http://www.fmva.unesp.br/ppfr). Foram utilizados 300 pintos machos Cobb 500, em arranjo fatorial 2x2 (com e sem TCP e com e sem o princípio de Mongin), num delineamento inteiramente casualizado, em 24 boxes (6 repetições por tratamento). As aves foram inicialmente alojadas em baterias metálicas (1-7 dias de idade), e posteriormente em piso (8-48 dias de idade), sendo arraçoadas com: (T1) dieta tradicional sem TCP; (T2) dieta tradicional com TCP; (T3) dieta com a aplicação do equilíbrio eletrolítico sem TCP e (T4) dieta com aplicação do equilíbrio eletrolítico com TCP. O condicionamento térmico foi realizado no quinto dia de idade, por 24 horas a 36 °C, somente na metade do lote (150 aves). Após esse período, todas as aves foram transferidas para boxes de 1,5x3m (12 aves/boxe), tendo como cama a maravalha de madeira reutilizada. Aos 36 dias de idade foi aplicado um estresse agudo (36°C) por 8 horas em todos os tratamentos, sendo monitorado eletronicamente a temperatura e a umidade do galpão e do microclima na altura das aves. A alimentação e a água foram ad libitum, mesmo durante o período de estresse. Foram aferidos os dados de desempenho aos 7, 35 e 48 dias de idade para ganho de peso, consumo de ração e conversão alimentar, e também a taxa de mortalidade de cada boxe. Verificou-se que tanto o equilíbrio eletrolítico como o condicionamento térmico precoce foram eficazes significativamente (P<0,05) para minimizar a mortalidade dos frangos submetidos ao estresse agudo de calor, sem prejuízo no desempenho das aves. Além disso, foi observado um efeito mais favorável quando aplicados simultaneamente (T4). Assim, para o tratamento em que nenhuma destas estratégias foram utilizadas (T1), a taxa de mortalidade foi 83% superior ao tratamento em que ambas foram aplicadas (T4). Assim, tanto o condicionamento térmico precoce como o princípio de Mongin foram válidos para minimizar os efeitos danosos causados pelo calor em frangos de corte.

Pets bring expressive benefits into the life of the elderly, so it becomes necessary to emphasize some of the concepts regarding responsible ownership consisting of a set of important attitudes that accounts for the well-being of all. In this context, non-governmental institutions represent an excellent mean of communication and information. Besides, the increase of the third aged people population indicates that a survey of parameters to this respect is necessary. Being thus, the objective of this work was to analyze the aged ones´ level of knowledge regarding their responsibility for their pet. A questionnaire was applied to 134 aged people, members of non-governmental organizations in the city of Araçatuba, SP, in order to find out how they took care of their pet animals. The pets aged from 2 to 336 months, being 43,3% mixed-breed animals. Out of that, 60,9% were male dogs and among cats, 65.2% were female cats. There was a 69.4% preference for dogs and a 17.9% preference for cats, only 10.5% of the elderly had preference for birds. From the descriptive statistics analysis it could be observed that 69.40% did not have any access to the street and that 50% did not have a veterinarian follow-up. Regarding vaccination it could be observed that 71.64% had received the rabies vaccine and 70.9% had received the combination vaccine. Also, 74.63% did not know the right moment to give medicines against animal worms. Another important fact was that 85.07% of the animals were not castrated and 84.91% were not under any preventive contraception method. In regard to food 50.75% of the animals were fed strictly with animal food, 12.69% with domestic food and 36.57% with both. Finally, 78.36% of the pets had never been ill. In this way, we can assure the importance of making responsible pet ownership measures well-known among third-aged people.
