Luta pela terra, luta pela palavra: história de vida e formação de duas educadoras populares do campo

This project has resulted from a reunion between me and two teachers with whom I had already worked, pedagogically counseling them during the execution of the Project of Youngsters and Adults Schooling at the Agrarian Reform Settlements in the State of Sergipe (PAJA/PRONERA) between 2002 and 2003. The matter that really motivated the research was related to the essential principle that guided the accomplishment of the PAJA s teachers education and professionalization: understanding their reality and knowing their needs, promoting the dialogue between scientific and common sense knowledge. Taking as a reference the fact that the teachers education is not restricted to the academic qualification, that is, that it is a part of the educational process, which, in turn, is a result of each one s personal background, dialectically individual and collective, the access to the teachers reality and needs was accomplished by studying their backgrounds, especially their school and professional career. They, inevitably, focused themselves on the country life s social and cultural context, that could be better understood by living together with the teachers during the twenty-seven days I stayed in the Golfo s settlement, located in the town named Pacatuba/SE. The approach to the teachers lives through their stories and the daily contact proved how much Science is still distant from the peasants routine, sometimes being presented to them as a finished product . That way, the dialog between those two categories and the expectation of the country life s social and cultural conditions, together with the education, in which teachers have an essential role, still remain as a challenge

Toxoplasmose canina: aspectos clínicos e patológicos

Inquiries about toxoplasmosis are essential because its zoonotic potential and pathogenicity in pets and production animals. The dog can be involved in the mechanical transmission of the infection by Toxoplasma gondii and in spite of not being the definitive host, it has an epidemiological role in this disease. The high rate of dogs naturally infected by T gondii and the great possibility of adquiring this protozoan, justify the importance of attempting against for the occurrence of this illness. The aim of this article was to demonstrated through literature revision, some clinical aspects, epidemic and pathological of the toxoplasmosis in the canine species.

O desafio da parceria na implementação do PRONERA: o caso do projeto alfabetização cidadã no nordeste Paraense.

El desafío de la parcería en la implantación del PRONERA: el caso del Proyecto Alfabetización Ciudadana en Noreste de Pará se constituye en un estudio sobre las políticas públicas de educación del campo. El trabajo tiene como objeto de análisis la implantación del PRONERA, a partir del estudio de caso del Proyecto de Alfabetización Ciudadana en Noreste de Pará, con el objetivo de comprender como la parcería, principio operacional y metodológico propuesto por el PRONERA, se concretó en la implantación del Proyecto y cuales sus posibles implicaciones en las políticas públicas de educación del campo. Entre los procedimientos metodológicos, realizamos la investigación bibliográfica y documental que nos permitieron situar la educación del campo en términos históricos y políticos, sistematizar la constitución y la organización del PRONERA y reflexionar acerca de la parcería a partir de diferentes ópticas. Realizamos también la investigación de campo por medio de entrevistas semi-estructuradas, con el propósito de analizar la implantación del Proyecto da Alfabetización Ciudadana, a partir del dialogo con los actores sociales involucrados. Los resultados de las análisis indicaron que, históricamente, las políticas públicas de educación destinadas a las poblaciones de la zona rural fueron instituidas verticalmente, desvinculadas de la realidad del campo e incompatibles con las necesidades e intereses de los sujetos. Constatamos que, en período reciente, movimientos sociales del campo reivindican y proponen acciones que se establezcan como políticas públicas de educación del campo. Identificamos que el PRONERA resulta de ese movimiento y se presenta como anuncio de una política pública de educación del campo, teniendo como diferencial el hecho de ser un programa del gobierno federal idealizado fuera de la esfera gubernamental, construido por los movimientos sociales del campo y presentar, entre otras innovaciones, el modelo de parcería y la gestión compartida, participativa y democrática. En esta perspectiva, en este estudio de caso, se evidenció que la parcería, frente a los conflictos y las disputas entre sus miembros participantes, no es el problema de la implantación del PRONERA, sino su punto fuerte. De este modo, la parcería es uno de los elementos necesarios para la construcción de políticas públicas, en particular, de educación del campo, una vez que posibilita la interacción de instituciones públicas y movimientos sociales locales, atribuyendo legitimidad a la educación del campo. Al promover un proceso de aprendizaje democrático, la parcería se presenta como estrategia de democratización de la educación del campo.

Helminth fauna of bovines from the Central-Western region, Minas Gerais State, Brazil

A prevalência e a intensidade de parasitismo por diferentes espécies de helmintos foram estudadas em bovinos da microrregião de Formiga, região Centro-oeste de Minas Gerais. Para tanto, foram necropsiados 76 bovinos naturalmente infectados, machos e fêmeas, SRD (sem raça definida) e de oito a 12 meses de idade. Os resultados necroscópicos revelaram a presença de nove gêneros e 16 espécies de helmintos, com a seguinte prevalência e média de intensidade de infecção: Haemonchus placei (100,0%; 3895,5); Haemonchus similis (29,0%; 159,6); Cooperia punctata (100,0%; 5595,0); Cooperia spatulata (32,9%; 137,8); Cooperia pectinata (34,2%; 1010,5); Trichostrongylus axei (69,7%; 239,2); Trichostrongylus colubriformis (10,5%; 10,8); Trichostrongylus longyspicularis (2,6%; 0,5); Ostertagia ostertagi (2,6%; 3,1); Ostertagia lyrata (2,6%; 1,5); Ostertagia trifurcata (1,3%; 0,3); Oesophagostomum radiatum (94,7%; 470,9); Trichuris discolor (47,4%; 32,5); Strongyloides papillosus (1,3%; 0,1); Capillaria bovis (9,2%; 10) e Bunostomum phlebotomum (2,6%; 0,3). A carga parasitária média foi de 11.558,5 helmintos por animal. Dos 76 bovinos necropsiados, 92,1% estavam infectados por três a sete espécies de helmintos. Apenas 7,9% dos hospedeiros mostravam-se parasitados por oito espécies diferentes de helmintos. Este estudo mostra o primeiro relato das espécies Ostertagia lyrata e Ostertagia trifurcata no Estado de Minas Gerais. É importante ressaltar que, no presente trabalho, por meio da identificação dos helmintos colhidos nas necropsias, foi possível observar que está ocorrendo uma inversão na intensidade parasitária média, com uma diminuição no número de Cooperia e um aumento nos valores de Haemonchus, em comparação com os valores relatados na literatura.

Histopathological analysis of the reproductive system of male dogs experimentally infected with Toxoplasma gondii

O presente trabalho teve como objetivo descrever eventuais alterações histopatológicas no sistema reprodutor (testículo e epidídimo) de cães machos experimentalmente infectados com Toxoplasma gondii. Para tal, 10 animais sorologicamente negativos para T. gondii foram selecionados e distribuídos em três grupos experimentais: GI - três cães inoculados com 2,0 x 10(5) oocistos da cepa P, GII - três cães infectados com 1,0 x 10(6) taquizoítos da cepa RH e GIII - quatro cães mantidos como controle. Pesquisa de anticorpos (IFI) contra T. gondii foi realizada. A infecção por T. gondii confirmou-se pela soroconversão de todos os machos infectados a partir do 7° e do 14° dia pós-inoculação (DPI) para cães que receberam taquizoítos e oocistos respectivamente. Decorridos 70DPI, realizou-se, em todos os cães, orquiectomia, e amostras (testículo e epidídimo) foram coletadas e processadas histologicamente para leitura em microscópio óptico. As seguintes alterações foram diagnosticadas: infiltrado inflamatório mononuclear leve e moderado em epidídimo, edema celular moderado, degeneração hidrópica e fibrose intersticial moderada em túbulos seminíferos. Os resultados histopatológicos do presente trabalho, aliados ao isolamento do T. gondii em fragmentos de testículo e epidídimo pela imunoistoquímica, juntamente com os resultados encontrados na literatura por outros autores em diferentes tecidos, permitem inferir que as alterações encontradas nos cães infectados com o respectivo protozoário são sugestivas de infecção toxoplásmica.

O currículo e as práticas pedagógicas na EJA: concepções e crenças dos professores da escola municipal Francisca Leonísia Cruz

The present investigation deals with the Curriculum and Pedagogical Practices of Young and Adults, EJA, and articulates with the conceptions and beliefs of teachers sitting. The empirical scope of this investigation consisted in the Municipal School Francisca Leonísia, located in the Agrarian Reform Settlement Serra Nova, city of Florânia/RN. Seeks to analyze the relationship between the Curriculum and Educational Practices of Young and Adult EJA - conceptions beliefs of these teachers. This work is based on qualitative research, interpretative character reflective and makes use of documentary analysis, structured interviews and reflective sessions as methodological procedures which ensure the achievement of our goals in research. These procedures allowed us to enter the practice setting and curriculum for teachers to understand how they think, prepare and practice of adult education in school curriculum research field. The documentary analysis provided the rethinking of the curriculum selected references, Political Pedagogical Project and Proposed Course of EJA, from a critical reading of concepts and conceptions given in these references, with a view to construction and reconstruction of concepts that reclaim the identity of young people and adult field, inserted in the Rural Workers Movement landless/MST. As reflective sessions were constituted in spaces of collective training and allowed the group to selfreflection e collective reflection about the ideas and beliefs that permeate the curriculum and guide their practices education in adult education. In these areas of training are also discussed current problems of adult education, the construction of an educational project of the adult education field to, warranties of learning and cultural identity of the adult education field and placed in the context of the MST. Under this view, it is concluded that the conceptions and beliefs of teachers seated directly relate to the curriculum designed, developed and practiced in adult education, as well as the educational practices that permeate the curriculum. This relation is in the midst of adversities of Rural Education, inserted in the Movement of Landless Rural Workers-MST, and requires the commitment of teachers to the necessary changes to an education are critical and emancipatory

Revelações e contradições entre concepção e gestão do currículo em um curso técnico no IFRN, na modalidade de educação de jovens e adultos

This dissertation reports the results of a research which has aimed to analyze the senses attributed to the curriculum by the students of the Technical Course of Computation Maintenance and Support, organized through the Programme of Integration of the the Professional Education with the Basic Education in the Youngster and Adult Education Modality (PROEJA), at Instituto Federal do Rio Grande do Norte (IFRN), Campus Santa Cruz. It has been sought to know who the students are and to investigate their curriculum conceptions, on which the this investigation has been based on. Thus, those senses attributed by the students on their narratives have been compared to the official proposed curriculum for the Programme and to the curriculum implemented by IFRN. The current research follows the qualitative approach being led by a study case and life stories methods. In order to effective that approach, two data collecting instruments have been developed: questionnaires and semi structured interviews. The collected data has been complemented by the legal and institutional documents analysis. This study is derived from the presupposition that PROEJA s students, although are able to access school after the educational system restructuration, are still facing difficulties during their courses because of the excluding and traditional curriculum, decontextualized with their personal and work life, that is, without curriculum integration. This study has accomplished PROEJA s students characterization presenting important data for the integrated curriculum construction at IFRN and revealing that the students consider the Programme as inclusive. Nevertheless, the practices concerned to the democratic construction of the curriculum and its dialogical action indicate partial inclusion, considering that, in order to include those students indeed, it would be necessary to include them to the institutional and academic context. Contradictory situations have been detected on the course pedagogical project, considered traditional and decontextualized, especially regarding to methodological aspects. The research also allowed to increase PROEJA s investigation field as well as to contribute with a better implementation of the Programme as curricular proposal bonded to Basic and Professional Education in the Youngster and Adult Modality Education Modality

EJA: saberes na articulação curricular da Escola Municipal Professor Amadeu Araújo

The target of this paper is to investigate the possibilities of inscribing into the EJA curriculum the knowledge detected in the neighborhood of a school if the point of view of the student body regarding the basic schooling deserves its due consideration. The empirical field of our research focuses on the elementary school of professor Amadeu Araújo Municipal School in Natal. Our investigative course tried to understand the way pupils think the curriculum contents of knowledge spread around the school from the vision furnished by their elementary school. With this, we hoped to develop a creative understanding concerning that question. Then we reviewed, along the debate, questions related to Nova Natal Housing Estate and its historic, social and cultural beginnings taking in account the participants memories of this research and their suggestions concerning the utility of the community knowledge to the curriculum practices. This project is supplied by the qualitative research and reinforced by the Focal Group s methodological procedures and semi-structured interviews. This procedure allowed us to discern different points of viewing, feeling and understanding in the complexity of the daily life around school and its environment. With these elements, we could note that some students perceptions pointed to a basic schooling fomented by traditionalized pedagogical practices in which teacher and pupil seldom dialogue with each other, what corroborates the impression of undervaluation of the pupil s role. Consequently, the nets of knowledge waved around the school in Nova Natal Housing Estate become useless, when they could be of great utility if inserted in the curriculum contents

Metodologia de implantação da construção enxuta: estudo de caso em construtora de porte médio

In recent years, the Brazilian construction industry has gone by changes like currency stability, increasing competition, shortage of skilled labor and increasing quality importance required by the customer, who made the sector companies seek solutions through new management practices in order to become more efficient. A alternative to these management practices is known as Lean Construction which is derived from the Toyota System Production. Lean Construction main goals are to reduce parts of activities that do not add value, increase product value by considering customer needs, reduce variability and production cycle time, simplify process by reducing the number of parts or steps, increase the flexibility in the product execution and transparency process, focus the control on overall process, introduce continuous improvement process, maintain a balance between improvements in flows and conversions and seek to learn from practices adopted by competitors. However, the construction industry is characterized by having nomadic activity, which undertakes an unique product with high cost of production and big inertia for behavioral change, making it difficult to implement the philosophy of lean construction in companies. In this sense, the main objective of this study is to develop a methodology for implementation of the principles of Lean Construction. The method of implementing the proposed management system was designed with the aid of 5W2H tool, and the implementation process is divided into three phases. The first one aims to know in a macro way the current operation of construction, identify who is its target audience and what are the products and services offered to the Market. The second phase aims to describe what actions should be taken and which documents are needed to be created or modified; finally, the third step goal consists in how to control and monitor established processes, where through Strategic Planning the company goals would be set along with their respective targets and indicators in order to keep the system working, aiming for continuous improvement with focus on the customer. This methodology was conceived as a case study analyzing a medium size construction with more than 18 years of activity and certified for almost 10 years with ISO9001 and level A in PBQP-H. We also conclude that this implementation process can be used in any developer and / or builder

Carbohydrate metabolism of Xylella fastidiosa: Detection of glycolytic and pentose phosphate pathway enzymes and cloning and expression of the enolase gene

The objective of this work was to assess the functionality of the glycolytic pathways in the bacterium Xylella fastidiosa. To this effect, the enzymes phosphoglucose isomerase, aldolase, glyceraldehyde-3-phosphate dehydrogenase and pyruvate kinase of the glycolytic pathway, and glucose 6-phosphate dehydrogenase of the Entner-Doudoroff pathway were studied, followed by cloning and expression studies of the enolase gene and determination of its activity. These studies showed that X. fastidiosa does not use the glycolytic pathway to metabolize carbohydrates, which explains the increased duplication time of this phytopatogen. Recombinant enolase was expressed as inclusion bodies and solubilized with urea (most efficient extractor), Triton X-100, and TCA. Enolase extracted from X. fastidiosa and from chicken muscle and liver is irreversibly inactivated by urea. The purification of enolase was partial and resulted in a low yield. No enzymatic activity was detected for either recombinant and native enolases, aldolase, and glyceraldehyde-3-phosphate dehydrogenase, suggesting that X. fastidiosa uses the Entner-Doudoroff pathway to produce pyruvate. Evidence is presented supporting the idea that the regulation of genes and the presence of isoforms with regulation patterns might make it difficult to understand the metabolism of carbohydrates in X. fastidiosa.

Effect of inclusion of citrus pulp in the diet of finishing swines

No primeiro ensaio foram utilizados 16 suínos machos castrados da linhagem Topigs, com peso inicial de 80,5±4,7 kg, para a avaliação biológica da polpa cítrica. Por apresentar 18,85% de fibra em detergente neutro e 41,18% de fibra solúvel em detergente neutro, a polpa cítrica mostrou-se como um ingrediente viável a ser utilizado em programas de restrição alimentar qualitativa. No segundo ensaio foram utilizados 36 suínos machos castrados, com peso inicial de 83,7±5,1 kg, recebendo rações com níveis de 0, 10, 20 e 30% de polpa cítrica. Os animais foram abatidos com peso próximo de 130 kg, sendo avaliados quanto ao desempenho e parâmetros séricos. Houve resposta quadrática (P<0,05) para ganho diário de peso e número de dias para atingir o peso de 130 kg, em função dos níveis de polpa cítrica na dieta, sendo observados melhores resultados com níveis de inclusão de 10,79 e 10,97%, respectivamente. Para os parâmetros séricos avaliados, não foi observado efeito (P>0,05) dos níveis de polpa cítrica sobre a uréia e triacilgliceróis, porém houve resposta quadrática (P<0,05) para o colesterol em função dos níveis de polpa cítrica.

Effect of adding macro and micro minerals in pig feces fed diets with different levels of probiotic

O objetivo deste trabalho foi avaliar dietas contendo diferentes doses (0, 100, 200 e 300 ppm) de probiótico sobre a produção diária de fezes (PDF) e teor de macro e microminerais nas fezes de suínos, nas fases de creche e de crescimento e no período total. A PDF, como porcentagem do peso vivo, somente apresentou diferença estatística (P<0,05) na fase inicial 1. Os teores de macro e microminerais excretados nas fezes não apresentaram diferença (P>0,05) entre tratamentos, a exceção de cálcio e sódio na fase inicial 1 e cálcio, zinco e níquel no período total. A adição de um poliprobiótico às dietas, não afetou a produção de fezes dos suínos nas fases de creche e de crescimento. Entretanto, a presença de microrganismos, adicionados (níveis de 200 e 300 ppm) às dietas reduziu a excreção fecal de cálcio, zinco e níquel.
