A escola rural e o desafio da docência em salas multisseriadas: o caso do seridó norteriograndense

Uno de los principales desafíos colocados a la educación del medio rural está relacionado a la enseñanza de las escuelas rurales con salas multifacéticas. Estas comprehenden alumnos de diferentes comunidades, series, edades, aprendizaje y niveles de conocimientos. Son cursos heterogéneos, que tienen como característica central la diversidad. En muchas regiones rurales de Brasil, la educación escolar es organizada en cursos multifacéticos debido a las grandes distancias entre las comunidades y el bajo número de alumnos en cada serie/año. Es común encontrar a los que están en fase de alfabetización estudiando con quien ya sabe leer y escribir - y todos sobre la orientación de apenas una profesora, que necesita enseñar a partir del contexto y la cultura local. El punto principal a ser tratado en este estudio está relacionado a las prácticas ejercidas en la acción educativa de las profesoras que actúan en escuelas rurales con salas multifacéticas de la región del Seridó do Rio Grande do Norte, precisamente en los municipios de Caicó, Jardim do Seridó y Ouro Branco. Creemos que este es uno de los puntos centrales en la discusión sobre la organización de la educación en el medio rural con fuertes implicaciones para el atendimiento cualificado de la población en condiciones de escolaridad de ese medio. Las contribuciones de Werthein y Bordenave, Calazans, Paiva, Ramalho, Therrien y Damasceno, Leite, Passador, Molina, Arroyo, Nascimento, Hage, además de documentos oficiales del MEC, como cuadernos SECAD, Ley de Directrices y Bases de la Educación Nacional, Directrices Operacionales para la Implantación de la Enseñanza Básica de 9 (nove) años, Proyecto Base del Programa Escuela Activa, entre otros, fundamentaron el análisis sobre la escuela rural y el desafío de la docencia en salas multifacéticas en el contexto del Seridó norteriograndense. El estudio envolvió 24 (veinticuatro) profesoras y 06 (seis) profesionales de la educación que desempeñan sus funciones en los Centros Municipales de Enseñanza Rural (CMER). Los instrumentos de investigación empleados fueron cuestionarios y observaciones aplicados para responder a las siguientes preguntas: ¿cómo se estructura la escuela rural con salas multifacéticas? ¿Cómo las profesoras se posicionan sobre su trabajo en salas multifacéticas esto es, como las concibe en el contexto de la educación rural del Seridó? ¿Qué opinan sobre la formación recibida para actuar en salas multifacéticas? Las profesoras y los/las profesionales de los CMER poseen en general formación superior en pedagogía, sin embargo, presentan limitaciones delante de las situaciones surgidas en el día a día de la sala de clases. El estudio revela que son las deficiencias de las políticas sociales y educacionales de formación docente, el bajo apoyo didáctico-pedagógico, reforzadas por la ausencia de un plano de carrera que dignifique el trabajo docente en ese medio, que generan limitaciones en el desarrollo profesional del magisterio rural, claramente junto a los docentes que actúan en salas multifacéticas en los municipios investigados

Survey on Chlamydophila psittaci in captive ramphastids in São Paulo State, Brazil

Chlamydophila psittaci (C. psittaci) has been detected in 460 avian species, among them the most frequent are the Psittaciformes, Columbiformes, Anseriformes and raptors. In Brazil, the main avian species recognized as healthy carriers belong to the order Psittaciformes and Columbiformes, but very few studies have been done in other bird families. Reports of the occurrence of this disease in the clinical form are rare in the Ramphastids; consequently, they are not commonly evaluated for this agent. The present study reports the investigation of C. psittaci in 25 captive ramphastids from a zoological park in São Paulo State, Brazil. Swabs samples from the cloaca were submitted to semi-nested polymerase chain reaction (semi-nested PCR) for direct detection of the microorganism. Additionally, blood samples obtained from these birds were submitted to the Complement Fixation Test (CFT) for detection of antibodies anti-C. psittaci. The presence of C. psittaci was not detected in the cloacal swab samples tested by the PCR. Nevertheless, 16% (4/25) of the bird's sera were positive by the CFT. Among the species with positive results, there are the saffron toucanet (Pteroglossus bailloni) and black-necked-aracari (Pteroglossus aracari), two species with no descriptions of the survey of C. psittaci published in the literature. Intermittent elimination of C. psittaci is a feature of chronically infected birds; however the absence of a positive-antigen sample did not guarantee that the bird is Chlamydophila-free. The serological results obtained show that the ramphastids tested were previously exposed to the pathogen and developed immune response, but showed no clinical signs of the disease and didn't eliminate regularly the organism in their feces in the moment of the sample collection.

Associação entre consumo alimentar e atividade física com a síndrome metabólica em mulheres na pós-menopausa

Post-menopause is characterized as the period beginning one year after the permanent cessation of menstrual cycles, which is typically related to medical disorders that, in association with Metabolic Syndrome (MS), represent a set of cardiovascular risk factors. Objective: To assess dietary intake and the prevalence of metabolic syndrome in postmenopausal women, according to the level of physical activity. Methods: The sample consisted of 82 women, evaluated in the Northern Zone of the city of Natal / RN who were participants in the Natal Active Program. People completed a Food Frequency Consumption Questionnaire (FFCQ) and were interviewed about physical activity. Anthropometric measurements and biochemical tests were used to diagnose MS (Metabolic Syndrome). Result: The active women consumed more protective foods (flaxseed, nuts, whole wheat bread, brown rice and olive oil) than inactive women. Risky foods (sugar, crackers, white bread, white rice, margarine and beef) were consumed more by the group of inactive women. The prevalence of MS was higher in inactive women (53.30%) than in physically active women (46.70%). Conclusion: Active post-menopausal women had a higher daily intake of protective foods in relation to cardiovascular disease, while the inactive post-menopausal women had higher intake of risky foods for such diseases

Crescimento e acúmulo de macronutrientes em chicória coberta e não coberta com polipropileno

O experimento foi realizado com o objetivo de comparar o crescimento e acúmulo de macronutrientes pela chicória coberta e não coberta com tecido de polipropileno (TP), branco de 20 g m-2. O delineamento experimental adotado foi de blocos ao acaso em parcelas subdivididas, com 4 repetições. Na parcela, os quatro tratamentos constituíram-se de duas cultivares de chicória crespa (Chicória Crespa e AF-218) em dois sistemas de cultivo (com e sem tecido de polipropileno) e nas subparcelas as épocas de avaliação da chicória, correspondentes às idades da planta (7; 14; 21; 28; 35 e 42 dias após o transplante). A semeadura foi realizada em 02/06/03 e o transplante em 27/06/03. Foi avaliada semanalmente a altura da parte aérea, número de folhas, diâmetro das plantas, matéria fresca e seca da parte aérea e o acúmulo de macronutrientes. Exceto para o diâmetro da parte aérea, observou-se superioridade das demais características nas plantas que receberam a cobertura com TP. A cobertura com TP por todo o período pós-transplante proporcionou maior acúmulo de P, K, Mg e S. Plantas da 'AF-218' cobertas com TP por todo período pós-transplante, e que apresentaram maior matéria fresca da parte aérea, acumularam 836; 515; 205; 144; 90 e 65 mg planta-1 de N, K, Ca, Mg, S e P, respectivamente.

Avaliação dos indicadores de desempenho de instituições federais de educação tecnológica doBrasil na abordagem do balanced scorecard

This Master of Science Thesis deals with a study on applying the BSC Balanced Scorecard to assess the performance of Federal Institution for Technological Education Institution in Brazil, a government organizations non for profit. It s accomplished a literature review in order to understand the BSC and its application to non for profit organizations and as a main result it is proposed a BSC conceptual model with an inversion of the main BSC perspective from financial to customer/society. It is used the annual management report of thirteen Institutions and applied a Pearson correlation analysis in order to verify a cause-effect situation between indicators. The main findings suggest that the model teachers qualification in terms of degree earned, quantity of teachers in full time job, and rate of students by teacher in full time job having good pearson correlation with the results expected of quality, throughput, social and demand response. However, the student unit cost use as the sole financial indicator did not get any reasonable correlation with the results, as so the quality and quantity of books in the libraries. Although it suggests a need for improvement in the model, the general model adopted appears to be satisfactory as a starting point to a BSC-like performance measuring system to this kind of Institutions
