O perfil de bem-estar dos beneficiários em idade economicamente ativa (BIEAs) do Programa Bolsa Família (PBF) : uma proposta de avaliação

O presente trabalho propõe uma avaliação do bem-estar social dos beneficiários em idade economicamente ativa do Programa Bolsa Família (BIEAs PBF) no município de Porto Alegre. Tal avaliação é norteada pela identificação de situações de restrições ou armadilhas (SACHS, 2005) da capacidade dos indivíduos escolherem diferentes estilos de vida, através dos papéis instrumentais da liberdade (SEN, 2010). Assim, são testadas hipóteses que envolvem as relações dos indivíduos com a escolarização, o mercado de trabalho e a renda. Os resultados da avaliação sugerem a existência de um nível de renda com restrições; incentivos para a interrupção do processo de escolarização, antes de um nível desejável; uma relação entre escolaridade e renda, pouco convergente; e um baixo acesso ao mercado de trabalho formal, prevalecendo relações de trabalho mais precárias. Finalmente, o presente trabalho propõe o posicionamento das questões relevantes atinentes aos BIEAs PBF em uma perspectiva mais ampla do desenvolvimento humano.

Cadernos de ensino e aprendizagem de ciências: reflexões sobre uma prática no programa escola ativa em classes multisseriadas

O presente estudo tem como objeto a prática pedagógica na mediação dos Cadernos de Ensino e Aprendizagem da área de Ciências Naturais nas classes multisseriadas, partindo do conceito de inovação pedagógica. Simultaneamente, elabora uma discussão densa acerca do ensinar/aprender ciências; dos Cadernos de Ensino e Aprendizagem; das classes multisseriadas e enfatiza a possibilidade de inter-relação com a inovação pedagógica, ao mesmo tempo em que reflete, explicita e analisa uma experiência pedagógica na qual a educadora compreende o sentido social da sua prática e se institui como organizadora de situações educativas, o que contribui para ratificar o caráter inovador do ensinar/aprender ciências numa classe multisseriada a partir do uso dos cadernos. Para investigar a mediação no uso dos cadernos da área de ciências, optámos pela pesquisa qualitativa, inspirando-nos na etnografia e seus dispositivos de investigação. Durante seis meses, vivenciamos o cotidiano da prática pedagógica da Escola Municipal Leovigildo Ribeiro dos Santos, localizada na zona rural do município de Feira de Santana-Bahia. Para investigar o objeto de pesquisa, utilizámos, dentre outros recursos metodológicos, a entrevista, a observação participante e a filmagem. A pesquisa realizada consubstancia-se numa experiência ímpar ao considerarmos que as mudanças implementadas na prática, de forma intencional e planejada, no sentido de romper com os mecanismos apresentados pelos cadernos apresentam uma nova possibilidade de ensinar/aprender ciências nas classes multisseriadas.

O programa escola ativa e inovação pedagógica: um estudo de caso etnográfico

Esta pesquisa apresenta os resultados do estudo sobre a prática pedagógica em uma classe multisseriada do programa escola ativa. A mesma tem como objetivo identificar a existência de práticas pedagógicas inovadoras na sala de aula do referido programa. Trata-se de um estudo de caso etnográfico, de abordagem qualitativa, o qual nos possibilitou a análise da realidade concreta, por meio da análise da documentação, observação do cotidiano da sala de aula e entrevistas. As relações que ocorreram no âmbito da escola, a análise dos fatos ocorridos e do discurso dos sujeitos se constituiu de grande importância para esta pesquisa. O campo de observação da pesquisa e coleta dos dados aconteceu na Escola Municipal Ernesto Geisel na Agrovila da Barragem no município de Lagoa do Carro, em Pernambuco. Participaram deste estudo, uma classe multisseriada do programa escola ativa composta por dezessete estudantes e uma professora. As aulas aconteciam à tarde. Os alunos cursavam o 4º e 5º ano do ensino fundamental da educação básica. Utilizaram-se, como procedimentos para coleta dos dados para o registro da prática pedagógica, relatórios e anotações em diários. Por se constituir uma pesquisa de natureza qualitativa, no decorrer do trabalho de campo, foi possível e necessária à flexibilização, alterações e ajustes (no decorrer do processo), haja vista a necessidade de alcançar os objetivos pretendidos. O estudo sinalizou para a necessidade de novas reflexões sobre a inovação nas práticas pedagógicas do programa escola ativa e educação do campo, pois se concluiu que, diferentemente daquilo que é descrito nos documentos oficiais, ela não está ocorrendo na prática, sendo necessária a ruptura com o sistema arcaico e tradicional de ensino e aprendizagem.

Fucana ativa via das Map quinases e inibe a proliferação de células de ovário de hamster chinês (CHO)

Fucan is a term used to denominate L-fucose rich sulfated polysaccharides. The fucans have been studied due their pharmacological activities like antithrombotic, antiproliferative and antioxidant. We have extracted three fucan fractions from the brown seaweed Spatoglossum schröederi. These fucans were denominated Fuc B 1, Fuc B 1.5 and Fuc B 2. The chemical analyzes show that the fucans have very similar composition as demonstrated by agarose electrophoresis gel, sugar and sulfate content. The antiproliferative effect was determined by MTT and BrdU methodologies in CHO cells. The inhibition of proliferation effect of the three fractions was about 40%. Therefore this we proceed just with the Fuc B 2 due the higher yield. There is no apoptosis indication using the anexin V/propidium iodide test. We found a cell cycle phase G1 arrest. The western blotting show that the PKC; pFAK; pERK 1/2 are activated when the cells were treated with fucans. The treatement with inhibitor of MAPK PD98059 extinguished the fucan effect. These results indicates that fucan act by the ERK pathway inducing the cell death.

Efeitos do tratamento superficial da sílica ativa com soluções de ácidos nítrico e fosfórico em propriedades do concreto

The addition of active silica potentially improves the quality of concrete due to its high reactivity and pore refinement effect. The reactivity of silica is likely related to its charge density. Variations in surface charge alter the reactivity of the material consequently affecting the properties of concrete. The present study aimed at investigating variations in the charge density of silica as a function of acid treatments using nitric or phosphoric acid and different pH values (2.0, 4.0 and 6.0). Effects on concrete properties including slump, mechanical strength, permeability and chloride corrosion were evaluated. To that end, a statistical analysis was carried out and empirical models that correlate studied parameters (pH, acid and cement) with concrete properties were established. The quality of the models was tested by variance analysis. The results revealed that the addition of silica was efficiency in improving the properties of concrete, especially the electrochemical parameters. The addition of silica treated using nitric acid at pH = 4.0 displayed the best cement performance including highest strength, reduced permeability and lowest corrosion current

Avaliação da efetividade de estratégias não farmacológicas para o alívio da dor de parturientes na fase ativa do período de dilatação no trabalho de parto

This study was aim to evaluate the effectiveness of strategies non pharmacological for the relief of the intensity of the parturient pain in the phase activates of the dilation period in the labor. Is a clinic rehearse of the type therapeutic intervention before and after" with a quantitative approach, accomplished in the Humanized Unit of Childbirth of the Maternity Januário Cicco School of the Federal University of Rio Grande do Norte, in Natal/RN, whit 130 parturient, being 30 in the pre-test of the strategies and 100 in the application of the strategies non pharmacological combined (breathing exercises, muscular relaxation and lombossacral massage) and isolated (shower bath in a normal temperature). We used the visual analogical scale to evaluate the intensity of the pain of the study parturient before and after" to the application of the strategies in the phases of acceleration, maximum inclination and desaceleration in the phase activates of dilation period in the labor. The principal results showed that the majority of the study parturient was between 20 to 30 years old (60%); with incomplete fundamental teaching (85%); family income until 2 minimum wages (74%); 78% had a companion and these, 44% were the own husband. The oxytocin was administered in the parturient during the phase activates of the labor in 81% of the cases and only 15% these women didn´t reciev anything medication. We verified significant relief (ρ=0.000) of intensity of the pain of the study parturient after application of the strategies non pharmacological combined and isolated. We concluded that the strategies non pharmacological combined and isolated were effective in the relief of the pain of the study parturient in the phase activates de labor

Atividades educativas aos portadores de periodontite crônica: escuta e troca de saberes no autocuidado em saúde bucal

This research aimed at evaluating oral health education activities for Periodontitis carriers, emphasizing the motivation for self-care and understanding the cultural aspects involved. This was a qualitative and quantitative study. Based on the qualitative referential, 20 interviews were done, in which differences between scientific and popular explicative models of the health-illness process were verified, besides the increased knowledge and motivation in relation to the use of preventive measures and also the fails in the understanding of the chronic character of periodontitis, enhancing frustration and guilty feelings in the patients. Two groups were structured: intervention and control. The intervention group was submitted to clinical attendance and education activities, while the control group undergone the traditional clinical attendance only. The sample consisted of 51 participants of intervention group and 47 of control group. Structured interviews were conducted at the beginning and at the end of the treatment in order to evaluate the knowledge and motivation for self-care in both groups. For comparison between the previous and post moments in both groups, there were applied McNemar tests with a probability of p < 0.05. In intervention group there was an increase in knowledge related to the name, the causes and related factors of the disease (p < 0.05). In control group there wasn t a rise in the understanding of the diseases chronic character, unlike in intervention group. However, in what concerns self-care, a greatest frequency in medium and high scores was observed in both groups. By this study, it is conclude that there is a common sense knowledge about the importance of preventive techniques and poor oral health as causing periodontitis; clinical interventions for bearers of chronic Periodontitis do not add values to the patients, regarding the illness, its causes and its chronic character; popular beliefs stay in their imagination, and the patients have a increased motivational capacity for self-care

Qualidade de abóbora minimamente processada armazenada em atmosfera modificada ativa

The active modified atmosphere effect was evaluated in the quality of squash fresh-cut (MP).. The squash pieces were conditioned in plastic packings and submitted the gases application in the following concentrations: 0.03% CO2 and 21% O-2 (controls T1); 5% CO2 and 4% O-2 (T2); 6% CO2 and 4% O-2 (T3); 7% CO2 and 4% O-2 (T4); 8% CO2 and 4% O-2 (T5). In T6 it was made vacuum application in the packing. The packings containing the squash were stored in to the temperature of 10 degrees C and relative humidity of 75% for 12 days. The evaluated analyses were weigth loss, total acidity (AT), pH, soluble solids (SS), ratio, firmness, color, antioxidant activity for DPPH and carotenoids content. The weigth loss was gradual and low until the ninth day of storage. The values of AT increased along the experimental period being superior for T1 and T2. The increase of SS during the storage of the fresh-cut squash went smaller for T3 and T4. The brightness stayed during the storage being superior for T5, already the color components red and yellow decreased along the experimental period.

Música, filosofia, formação: por uma escuta sensível do mundo

La musique, plus qu`um mot et le texte écrit, a le pouvoir de produire le déplacement du sujet en relation aux contingences du temps e de l´espace. Entendre de la musique est plus que de l´amusement. Comme un artifice cognitif qui ultrapasse l´expérience analytique e métonymique, les formes tonales doublent la réalité, expandent les sens, actionent l´imagination, retotalisent les sentiments, amplient les expériences, permettent la rencontre du sujet avec les éssences des phénomènes qui ne sont pas traductibles par les mots. Nous écoutons de la musique pour restituer notre dignité e conférer à la vie plus de vérité, plus de concrétion (Santiago Kovadloff). La mélodie permet l´expérimentation des états de cohésion, de conéction pleine entre sens et intention, entre commencement et fin, de la finitude de la vie (Schopenhauer). Le phénomène musical provoque l´expréssion de la douleur, de la souffrance et, au même temps, du jubile et de la joie, réliant nature et homme (Nietzsche). Tenant comme base cette compréhension, la dissertation tient dans la musique une importante métaphore pour comprendre la complexité humaine, une fois qu´elle propicie une écoute sensible du monde et mobilise dans le sujet l´expérimentation de divers états de l´être. Nous pouvons dire que la musique est un opérateur de la conaissence parce qu´elle fait affleurer l´écoute intérieure, la rencontre du sujet avec lui même. Cet opérateur cognitif actione les pôles de l´ésprit qui font dialoguer sensibilité, éthique et esthétique, ordre et chaos, silence et bruit, mouvement et pause, repétition et inovation. Par l´expérience musicale, nous habitons des formes hibrides de sensibilité et raison. L´inachèvement, notre principal caractéristique comme humains, a, dans la musique, une image impair, parce que la musique est l´expression du dévir. Pour tisser ces arguments, la dissertation part des études de Schopenhauer et Nietzsche sur la musique, esthétique et métaphysique; Expose des fragments de la biographie de trois grands penseurs contemporains (Werner Heinsenberg, Ilya Prigogine et Edgar Morin) accentuant la présence de la musique en ses vies; et, par fin, présente ce que nous appelons biographies sonores de quatre artistes-musiciens brésiliens (Benedito Juarez et Gil Jardim, de São Paulo, et Ronaldo Ferreira de Lima et, Cleudo Freire, du Rio Grande do Norte)

Avaliação do programa escola ativa como política pública para escolas do campo com turmas multisseriadas: a experiência em jardim do seridó/rn (1998-2009)

This work aims at developing an evaluation of the implementation of the Program Escola Ativa as a public policy for rural schools with combined grade classrooms in Jardim do Seridó RN (1998 2009) focusing on the following dimensions: school s physical environment, training, follow up, and didactic usage of the methodology. In order to develop this research we refer to the literature that analyzes the cycle of policies (FREY, 2000). In this approach, evaluation represents an important step in the process of analyzing the implementation of public policies, as a way of measuring up their performance, as well as a guide for realignments and redefinitions (PRESSMAN; WILDAVSKY, 1998). In order to accomplish this function, the evaluator of policies must be acquainted with scientific concepts and methods that consist of describing, interpreting and analyzing the policies in the governmental sphere (MENY; THOENIG, 1992; LIMA JÚNIOR, 1978). In this perspective, we intend to investigate whether in its proposition of minimizing the blanks in the Brazilian educational system, the implementation of the Program would be contributing to the improvement of the political-pedagogical practices in the rural schools with combined grade classrooms in Jardim do Seridó RN. In order to do this research, we have developed a theoretical-methodological matrix made of analysis dimensions, variables, indicators and instruments, such as literary revision, documental analysis, semi-structured interviews with four teachers and three supervisors that work and/or have worked in Escola Ativa in that town in the period comprised among 1998 2009, besides notes taken from field observation and photographs from four rural schools with combined grade classrooms. With this research we have identified that the Program, at a national level, has gone through different phases in its implementation process, for the town was not ready to fully take the responsibilities of the autonomous expansion, in 2002. From that period on, the execution of Escola Ativa has suffered several discontinuities, such as the lack of professional training and supervising. It is also noted that the methodology contributes to the dynamization of the didactic-pedagogical activities and promotes the cooperation and autonomy of the students in the organization and the applicability of the components of the curriculum, especially of Governo Estudantil and Cantinhos de Aprendizagem. Although the directions of the Program (BRASIL, 2005) point out that Escola Ativa has among its principles social transformation, we identified that, isolated, the initiative is not capable of promoting the changes that the rural schools need, namely investments in the physical, material, pedagogical and technological infra-structure, besides the estimation and a career plan for the teachers. In a general draft of the results of this research, we realized that some aspects presented about the peculiarities of Escola Ativa in Jardim do Seridó as a governmental Program, reinforce the need for the public policies to be evaluated, in order to confront critic and operationally the planning with the practice, revising action, whenever necessary
