Opiniões sobre estágio curricular e prática de ensino na licenciatura em química: o caso do CEFET-PB

The Brazilian legal documents are directing the reformulation of the courses that prepare students to be teachers. Through out the country many institutions look for to fit themselves in such documents. On the other hand, other IES (Superior Education Institutions), when they are setting up such courses they looked for to be adequate to the new public politics. Based on the National Curricular Norms to form teachers for Basic Education, in tertiary level, in 2004 it was created at the CEFET-PB,the Chemistry Course (Licenciatura) to prepare people to be teachers, whose organization. This work presents the results of a research of phenomenological nature that aimed to comprehend the teachers opinions, in the range of discussions about the current politics of formation, particularly related to the CNE/CP 1 and CNE/CP 2/2002 resolutions. This work based on the curricular proposal for the Chemistry Course (Licenciatura), presents the relationship between the probationary period and the teaching practice at the CEFET-PB, in order to contribute for a reflection about these categories to clarify the teachers of the course. It started from the consideration of all changes operated in contemporary society implies changes on teacher's pedagogical practices. It was used tow instruments for the data collection: a questionnaire with open and closed questions and recordable interviews. Nine teachers form the CEFET-PB took apart and four licensed teachers. It was based in a theoretic frame as a support for discussions about the different models of teachers formation. We concluded that the representations of teachers about probationary period the practice on the activity for the teachers formation was strongly anchored in characteristic elements of the formative tendency of a institution that historically acted on a technician formation, and the results pointed to strong signs of attitudes based on a model of the technical rationality

Estágio menopausal e níveis hormonais no desenvolvimento muscular e funcional em mulheres de meia idade: um estudo transversal

Introduction: Hypoestrogenism is the main characteristic of female aging. It promotes significant changes in body composition, both in fat mass as in lean body mass, leading to a decrease in muscle strength and physical performance. Objective: The aim of this study was to test whether menopausal status and hormone levels are associated with muscular strength and physical performance in middle-aged women. Methods: In a cross-sectional study it was collected sociodemographic data, gynecological history, anthropometric and biochemical measures in women aged 40 to 65 years in Parnamirim-RN. The menopause status (pre, peri and post menopause) was determined by menstrual history. All women underwent three dimensions of physical performance assessment: handgrip dynamometry, gait speed and chair stands test - Short Physical Performance Battery (SPPB). Categorical data were presented as absolute and relative frequencies. Quantitative data were showed as mean and standard deviation and the normality of distribution was verified with Kolmogorov-Smirnov (KS) test. Biochemical measures of estradiol and follicle-stimulating hormone (FSH) were transformed to log10. ANOVA with Tukey post-test for comparison of variables between the groups pre, peri and post-menopausal was performed and then multiple linear regression analyzes. Results: Two hundred and seventy eight women aged 50.2 (±5.58) years composed this study, being 50 women in premenopausal status (18%), 122 in perimenopausal (43.9%), and 106 postmenopausal stage (38.1%). The groups were different in age (p=0.001), marital relationship duration (p <0.001), number of pregnancies (p=0.001) and parity (p=0.001). Differences in biochemical measures were observed among the groups: estradiol (p<0.001), FSH (p<0.001), total cholesterol (p=0.001). There were no differences in gait velocity between menopausal status. Values in mean of grip strength decreased by postmenopausal women to perimenopausal and premenopausal ones (24.5 ± 5.1, 25.6 ± 5.4, 26.9 ± 4.9 for post-stage, pre and peri menopausas, respectively, p = 0.02) and the performance of chair stands test was better in premenopausal women compared with that in peri and postmenopausal status (p = 0.02). In multiple linear regression for muscle strength, the variables that remained were: age, estradiol and somatic symptoms measured by Menopause Rating Scale-MRS (R2=0.15). While for the xiv chair-stands test the predictors were number of births and FSH values (R2=0.04). Conclusion: There is a relationship between the stages of menopause and muscle performance in measures of grip strength and sit-up test and these are influenced by the fall of estrogens levels. Data suggest that the decrease in muscle strength and physical performance already appear in the transition to menopause stage, pointing to the need for more research in this area and appropriate preventive interventions

Avaliação do programa de tutorização da EMATER-RN para servidores em estágio probatório

The present thesis evaluated the contributions and limitations of the tutorship program introduced in EMATER-RN, as a tactic of organizational socialization for civil servants in probationary stage. Tutorship was understood as an intensive and continuous relational process, in which a more experienced person in the organization the tutor offers psychosocial support, stimulates the development of the professional career and enables to the newcomer the tutee learning on job performance. The organizational socialization was considered in the perspective of the symbolic interactionism. The study was characterized as a program evaluation and as an action research. The practical interventions for the program implementation were conducted and, at the same time, the evaluations of process, results and reaction to the program were applied. Among the major contributions of the action research, it stood out: the diagnosis of reasons for the formation of the pair and of expectations of tutors and tutees, the improvement of the tutorship registration tools, the ascertainment of the success of the program in the socialization of the new civil servants, the confirmation of the importance of the compatibility among them and of the adequate performance of tutorship functions for achieving its benefits. Based in constraints of the program, one may quote as essential recommendations: the formation of a technical team supporting the program, the clear establishment of deadlines for each procedure and the reinforcement to its compliance, the investigation of the functions performed by the tutor, the sensitization of the managers to the resolution of problems that affect the program, the voluntary participation of the tutor and the continuous meetings of tutors and tutees. One settles for the relevance of the program and in favor of its continuation, provided that its improvement and systematic management are conducted.

Concepções e práticas da psicologia escolar :um olhar através do estágio curricular supervisionado

School psychology can be considered a growing professional field in Brazil, in spite of the difficulties concerning both the role of the psychologists in the schools and the restrictions of the labor market. Professional training is one of the most problems faced by the area. The present study is an attempt to investigate the conceptions of school psychology and the practice of the school psychologists inside de educational agencies, from the point of view of the professional training, expressed by curricular supervised training. The reason for this choice was the important role played by supervised training in the process of professional training. To carry out this study, supervised training reports written in the 1980s and the 1990s used in the student evaluation process were examined. As the main results, we point out the co-existence during the 1980-decade of two models of psychological practice: the clinical and the educational, with the dominance of the first one. During the 1990-decade, we can observe the co-existence of the same models with the dominance (but not the hegemony) of the educational model, as shown by the activities of the students. In the 1980s, for instance, the most common activities were observation of the children (45.9%), teachers guidance (40.5%) and psychodiagnostic (37.8%). In the 1990s, the main activities were participation in staff briefings (66.6%), parents guidance (58.0%), teachers guidance (50.0%) and students counseling (41.6%). Aspects related to the importance of professional training - represented by curricular supervised training - to the professional practice are discussed

O estágio não-obrigatório na formação profissional dos(as) assistentes sociais: trabalho precarizado ou processo didático-pedagógico?

Coexisten, en el universo académico, prácticas curriculares obligatorias y no obligatorias que pueden ser remuneradas o no. Delante de la constatación de lagunas en la concepción, gestión y operacionalización de las prácticas no obligatorias remuneradas, escogimos este tema como objeto de nuestra investigación, tratando de analizarlo en el contexto de los cambios sociohistóricos contemporaneos y su influencia en la cualidad de la formación profesional del estudiante de la carrera de Servicio Social. Este estudio tiene como ¨locu¨ de investigación la Facultad de Servicio Social del Estado de Rio Grande del Norte (FASSO/UERN). Este estudio se caracteriza por la adopción de una perspectiva de análisis cualitativa, con la expectativa de develarlo mucho más allá de lo que se muestra en su aparecncia. Para esto, realizamos revisión de literatura, análisis de documentos, observación asistemática y entrevistas con estudiantes y profesionales de las entidades que ofrecen prácticas a los estudiantes. Además se incluyó, en los procedimientos metodológicos, la aplicación de encuestas y conversaciones informales. Constatamos la existencia de lagunas en el desarrolllo de las prácticas no obligatorias remuneradas, ocasionadas por la ausencia de supervisión y por la inclusión de pasantes en sectores y/o actividades desvinculadas de su futura profesión. La investigación nos permitió desvelar situaciones en las que la oferta de plazas ocurre en detrimento de la contratación de empleados, lo que configura un distanciamento de este componente curricular del área de formación profesional, desvirtuando su carácter educacional. Cientes de la coexistencia contradictoria entre situaciones ventajosas y problemáticas en las prácticas no obligatorias remuneradas para el proceso de formación profesional de los asistentes sociales, concluimos que esta modalidad de práctica cuando vinculada a la intervención de la facultad y bajo la supervisión de asistentes sociales, independiente de sus implicaciones en los intereses del mercado, potencializa el desarrollo de competencias y habilidades intrínsecas al proceso de formación profesional; pero si distanciada del área de formación y/o sin el debido acompañamiento didáctico-pedagógico establece poca o ninguna relación con la formación de los asistentes sociales. Pero, incluso distanciadas del ejercicio y de la formación académica en el área de servicio social y/o (llenas de aspectos frágiles) llenas de fallas en el proceso de enseñanza y aprendisaje, estas experiencias ejercen profunda influencia en la formación de los asistentes sociales, pudiendo fragilizar el compromiso con el proyecto ético-político, diseminar el aspecto subalterno de la profesión y hacer confuso y conflictivo el proceso de construcción de la identidad profesional. En este sentido, las inversiones de capital para reducir los gastos con mano de obra, las dificultades vividas por las universidades públicas brasileñas para garantizar la cualidad de la enseñanza delante de la insuficiencia de recursos humanos y materiales y la desvalorización de los componentes no obligatorios del proceso de formación profesional de los asistentes sociales, son factores que obstaculizan el reconocimiento y la materialización del potencial didáctico-pedagógico de las prácticas

Avaliação quanto à presença de microalbuminúria e hiperfiltração glomerular no estágio de tolerância à glicose diminuída

Na fase de tolerância à glicose diminuída (TGD) já estão presentes vários distúrbios metabólicos característicos do diabetes mellitus tipo 2 e fatores de risco que predispõem à vasculopatia. Nosso objetivo foi o de verificar se indivíduos de nossa população, com TGD e normotensos, apresentam elevação da excreção urinária de albumina (EUA) e da depuração de creatinina (D Cr). Teste oral de tolerância à glicose padrão com dosagem de insulina foi realizado, classificando os participantes em dois grupos: com TGD e com tolerância à glicose normal (TGN). Urina do período noturno foi utilizada para a determinação da EUA (imunoturbidimetria) e da D Cr. Os dois grupos não diferiram quanto à EUA e à D Cr. A freqüência de microalbuminúria foi de 21,1 e 3,3%, respectivamente, para os grupos com TGD e TGN (NS). Concluímos que, nesta amostra da população brasileira, indivíduos com TGD, normotensos e com resistência à insulina não apresentaram microalbuminúria e hiperfiltração glomerular.

Reações comunicativas dos alunos de enfermagem frente ao primeiro estágio curricular

Este estudo tem como objetivo descrever as reações que os alunos de enfermagem apresentaram quando do seu primeiro estágio curricular. É um estudo transversal e de campo, e o tratamento dos dados foi realizado com base no método de análise de conteúdo. Os resultados descrevem o campo de estágio, o relacionamento com a equipe da enfermaria, com os pacientes e com o docente durante este período. Nas conclusões, podemos afirmar que o estresse e as contradições vivenciadas no primeiro estágio são parte do crescimento e aprendizado do aluno. O professor é maior responsável por determinar o tipo de interação que haverá entre ele e o aluno, cabendo-lhe ouvir, incentivar e capacitar-se para apoiar os alunos nas experiências iniciais da prática, para que o primeiro estágio seja um fator motivador ao aluno.

O graben de Palestina: contribuição à estratigrafia e estrutura do estágio rifte na bacia do Araripe, nordeste do Brasil

The Palestina Graben is one of the NE-trending asymmetric grabens of the Araripe Basin. This basin rests on the precambrian terrains of the Transversal Zone, Borborema Province, immediately to the south of the Patos Lineament. It is part of the Interior Basins province of Northeastern Brazil, being related to the fragmentation of the Gondwana supercontinent and the opening of the South Atlantic ocean. The Palestina Graben trends NE-SW and presents an asymmetric geometry, controled by the NW extensional eocretaceous strain. The graben borders display distinct geometries. The SE border is a flexural margin, characterized by the non conformity of the eopaleozoic Mauriti Formation (the oldest unit of the basin) overlying the crystalline basement, but also affected by normal faults with small displacements. On the opposite, the NW border is continuous and rectilinear, being marked by normal faults with major displacements, that control the general tilting of the layers to the NW. In this sense, the Mauriti Formation is overlain by the Brejo Santo, Missão Velha (which also occurs in the Brejo Santo-Mauriti horst, to the NW of the fault border) and Abaiara formations, the latter restricted to the graben. The interpretation of available gravity data and a seismic line indicates that the main fault has a variable dip slip component, defining two deeper portions within the graben, in which the sedimentary column can reach thicknesses of up to 2 km. Regarding to the stratigraphy of Araripe Basin in the study area, the sedimentary package includes three distinct tectonosequences. The Paleozoic Syneclisis Tectonosequence is composed by the Mauriti Formation, deposited by a braided fluvial system. The Jurassic Tectonosequence, whose tectonic setting is still debatable (initial stage of the Neocomian rift, or a pre-rift syneclisis ?), is represented by the Brejo Santo Formation, originated in a distal floodplain related to ephemeral drainages. The Rift Tectonosequence, of neocomian age, includes the Missão Velha Formation, whose lower section is related to a braided to meandering fluvial system, outlining the Rift Initiation Tectonic Systems Tract. The upper section of the Missão Velha Formation is separated from the latter by a major unconformity. This interval was originated by a braided fluvial system, overlain by the Abaiara Formation, a deltaic system fed by a meandering fluvial system. Both sections correspond to the Rift Climax Tectonic Systems Tract. In the area, NE-trending normal to oblique faults are associated with NW transfer faults, while ENE to E-W faults display dominant strike slip kinematics. Both NE and E-W fault sets exhibit clear heritage from the basement structures (in particular, shear zones), which must have been reactivated during the eocretaceous rifting. Faults with EW trends display a dominant sinistral shear sense, commonly found along reactivated segments of the Patos Lineament and satellyte structures. Usually subordinate, dextral directional movements, occur in faults striking NNW to NE. Within this framework bearing to the Palestina Graben, classical models with orthogonal extension or pull-apart style deserve some caution in their application. The Palestina Graben is not limited, in its extremeties, by E-W transcurrent zones (as it should be in the case of the pull-apart geometry), suggesting a model close to the classic style of orthogonal opening. At the same time, others, adjacent depocenters (like the Abaiara-Jenipapeiro semi-graben) display a transtensional style. The control by the basement structures explains such differences

Estágio de colheita e substrato para o teste de germinação de sementes de ipê (Tabebuia chrysotricha (Mart. ex DC.) Standl.)

Durante o processo de maturação, as sementes passam por modificações físicas, bioquímicas e fisiológicas até atingir o ponto ideal de colheita, quando apresentam a capacidade máxima de germinação e vigor. O objetivo deste trabalho foi identificar o estágio de colheita e o substrato mais favorável à germinação das sementes e ao crescimento de plântulas de Tabebuia chrysotricha. Os frutos de T. chrysotricha foram colhidos em 16 árvores- matriz na Fazenda Lageado, em Botucatu, SP, em quatro estágios de colheita: fruto fechado menor (ME), fruto fechado maior (MA), fruto em início de abertura (IA) e fruto aberto e em início de dispersão das sementes (D). Para caracterizar os estágios de colheita, foi utilizada a coloração dos frutos e das sementes, mensurados a espessura, a largura e o comprimento dos frutos e determinado o teor de água das sementes. O efeito do estágio de colheita sobre a qualidade das sementes foi verificado mediante o teste de germinação sobre areia e sobre papel a 25 ºC, avaliado após 21 dias da semeadura; e o vigor, pelo teste da primeira contagem (7 dias) e do comprimento de plântulas (21 dias). Os resultados indicaram que as sementes de Tabebuia chrysotricha devem ser colhidas quando o fruto estiver em início de abertura. Este estágio de colheita também pode ser identificado pelo teor de água das sementes de 59,6%. O substrato areia mostrou-se mais favorável ao teste de germinação e ao crescimento das plântulas.

Efeito da aplicação de etileno no pH, acidez, índice refratométrico e açúcares totais de frutos de manga, colhidos em estágio pré-climatérico

Este trabalho teve como objetivo o estudo da ação do etileno no amadurecimento de frutos de manga, tentando contribuir para o conhecimento da fisiologia do amadurecimento destes frutos. Foram utilizadas mangas (Mangifera indica L.), variedade Keitt, colhidas em estágio pré-climatérico. Estes frutos receberam tratamento com ethrel (500 e 1.000 ppm, com exceção da testemunha) e foram submetidos às seguintes determinações: pH, acidez, índice refratométrico e açúcares totais. A análise e interpretação dos resultados mostrou a inexistência de diferença estatística entre esses 3 tratamentos, indicando que a aplicação de ethrel não trouxe nenhuma vantagem na melhoria de qualidade dos frutos.

Oferta e distribuição de estágio supervisionado em cursos de odontologia do estado de Minas Gerais, Brasil

Since 2002, which are in effect the Curriculum Guidelines for National Graduate courses in dentistry. The adequacy of the education needs of the Unified Health System is one of its main goals. As guidance, a way of achieving this goal is through supervised, which are presented as a tool for improving the academic scientific and technical, providing you know the reality of health and society in which to work. This study aims to examine the supply and distribution of supervised in graduate programs in dentistry in the state of Minas Gerais - Brazil. The material for analysis was obtained by sending letters to courses and consulting to its sites on the Internet. Were part of the study, 15 of the 23 courses in the state. It appeared that the load-hours of supervised showed variations between 315 and 975 hours, with only 20% of courses devoted 20% of the total working hours of supervised practice. There was no correlation between the total working hours of the course and working hours of supervised practice. The courses in which the supervised activities were represented only by extra muros showed a lower percentage of working hours in relation to total working hours of the course.
