O percurso da ressignificação de si : do esporte à formação do professor de dança

The present work is characterized as a research-formation study. The author analyses his trajectory as dance professor, observing processes of transition in the perception of the body: from the mechanical body to the sensitive body. He tries to outstand this new meaning of the body and the dance teaching and artistic experience as the matter that instructs itself. This research puts together the experience of two teachers, one of them as student (researcher), while the other, as master and professor (collaborator) and intends to comprehend how this new meaning of the body was brought to each one s life, motivated by the dance. It is used the self biographic method and the research-formation methodology to analyze and identify common points between their self formation processes. The researcher and collaborator life narratives as well as a partially structured interview with the collaborator were used as investigation source. The analysis followed the models suggested by Schütze (1977), presented by Bauer and Jovchelovitch (2004), guided by the five pillars of the study: the Subject aspect, as guiding point for the analysis; Corporal aspect, as component and integrant element of an individual and of the dance; the Dance while seen as forming and guiding practice for the individuals researched; the Complexity aspect; and finally the Instructor and Professional Formation, emphasizing the self formation process. The results showed how the dance has changed their perception of their own bodies and the whole corporal aspect, leading to subject-actor body point of view, and no longer from a strictly mechanic perspective. The teaching trajectory was defined by the new evaluation of the body through the Dance bringing the individuals researched to a dialogical-reflexive teaching practice that motivates self consciousness, humanization and automatization, in the context of their background experiences and the environment they act

PROEJA FIC/Fundamental no IFRN-Campus Mossoró: das intenções declaradas ao funcionamento de um curso em espaço prisional

This research aims to analyze the FIC Course of Assistant Technician in Service Management and Quality, integrated to elementary education / EJA form developed by IFRN MO Campus between 2011 and 2013 in the form of a PROEJA FIC / AT ELEMENTARY SCHOOL LEVEL. We seek to understand the adhesion between the national guidelines postulated for the Program, established in PPC and mediations with the process conceived in the run of the course. Guiding by the socio-critical approach and the dialogical paradigm, the theoretical-epistemological mark is especially buoyed by the theoretical contributions of Ciavatta (2005) , Rock (2011) , Haddad and Di Pierro (2000), Freire (2005), Marx (1982), Ramos (2005), Frigotto; Ciavatta; Ramos (2005), Moura (2012), and also on education in prisons by Onofre (2007, 2011), Bueno (2007), Julião (2011) and Foucault (2001). We assume that an action that enables professional qualification as FIC courses articulated to the EJA in the context of education in prisons have conceptual, methodological, political and pedagogical implications for it focuses challenges, weaknesses and opportunities on the same area of education., We have developed four techniques of data collection based on procedures and tools of qualitative research, such as document analysis, a student survey, the conduction of focus groups with teachers and administrators of the course and on-site observation. Mediated by the investigated context, results showed that the consolidation of PROEJA FIC / AT ELEMENTARY SCHOOL LEVEL goes beyond the intentions officially declared. It is inferred that after seven years of its creation, even though it keeps some potential, this program is not being satisfactorily developed and it shows weaknesses national and locally, it is set at low capillarity, it has a limited scope, and dissolved essential public commitments to the course development. The effectiveness of PROEJA FIC / AT ELEMENTARY SCHOOL LEVEL as part of an emancipatory inclusion social policy, according to official statement, entails approximating the legal logic with social logic, so as not only to propagate discourses and enforce worship to specific and successful experiences that reach only a minority, but to provide actual and necessary conditions to promote the breadth and social quality of the offered deals in this program format

O ensino de enfermagem gerontológica na formação do enfermeiro

At the current time of demographic changes in the world , it is observed that the health sector requires restructuring of its practices in caring for the elderly , in order to enable a comprehensive and humane care . In this sense, we identify the need for qualified professionals to assist the elderly and, therefore , it is important that training curricula are adequate to this reality . The study aims to analyze how it develops teaching gerontological nursing component in undergraduate nursing . This is a descriptive , exploratory study with a qualitative approach, in two higher education institutions in the city of Natal / RN . The population involved corresponded to the coordinators of graduate courses in nursing and teachers who teach content of health care for the elderly, a total of seven participants . The data collection instruments were used: a questionnaire containing questions related to the characterization of the participants and the teaching of gerontological nursing in undergraduate courses in nursing and a form with items of analysis for pedagogical projects . The results were presented descriptively in tables and analyzed from coming themes of the main themes of the instruments defined in: knowledge about the research participants , knowledge of teaching gerontological nursing component and knowledge of pedagogical projects , discussed under Resolution paragraph . 03 of 7/11/2001 , which establishes standards for the nursing program , the educational projects of educational institutions , the Theoretical Donald Shoon and thematically relevant literature . The results indicate that the majority of participants were female (four), all have graduate though , none of them stated in the qualification of aging or elderly health area; the organization of the contents of the component in the curriculum, workload theoretical- methodological and practical teaching strategies presented was heterogeneous and sometimes diverging at the same institution . On the definition of gerontological nursing component was identified that is not well defined along the pedagogical design of educational institutions surveyed . It was concluded that in the context of this study , teaching gerontological nursing is present in the course of nursing education, but needs reevaluation and updating in order to teach a wider range of driving and health practices

Disponibilidade de nutrientes no solo: decomposição e liberação de compostos orgânicos de resíduos vegetais

O objetivo principal desta revisão foi reunir informações a respeito da ação de compostos orgânicos produzidos por plantas na disponibilidade de nutrientes nos solos, principalmente sobre os cátions Ca, Mg e K e sobre o ânion fosfato. O sistema de cultivo adotado ocasiona mudanças nas propriedades químicas e físicas do solo, especialmente na disponibilidade de nutrientes e condicionamento físico do solo. Tem-se observado o acúmulo de nutrientes nas camadas superficiais do solo no sistema de semeadura direta, pelo não-revolvimento do solo e pela deposição de resíduos de culturas na superfície. Os ácidos orgânicos provenientes de plantas podem interagir com a fase sólida e ocupar os sítios de adsorção de nutrientes, competindo diretamente com eles e aumentando sua disponibilidade no solo. A adição de resíduos vegetais pode promover, antes da humificação, a elevação do pH, por promover complexação de H e Al com compostos do resíduo vegetal, deixando Ca, Mg e K mais livres em solução, o que pode ocasionar aumento na saturação da CTC por estes cátions de reação básica. Também é normal observar o aumento na disponibilidade de P no solo com a adição de resíduos vegetais, tanto pelo P presente no resíduo como por competição de compostos orgânicos dos resíduos pelos sítios de troca no solo. A persistência dos compostos orgânicos também é fator que tem grande interferência nos processos de sorção/dessorção de cátions e ânions, dependendo da atividade microbiana, da disponibilidade metabólica do substrato carbonado e da sorção aos colóides do solo.

Obtenção de ferrita de cobalto através de dois métodos de síntese: método de complexação combinando EDTA/Citrato e método hidrotérmico

In this work it was synthesized and characterized the cobalt ferrite (CoFe2O4) by two methods: complexation combining EDTA/Citrate and hydrothermal investigating the influence of the synthesis conditions on phase formation and on the crystallite size. The powders were mainly characterized by x-ray diffraction. In specific cases, it was also used scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), x-ray fluorescence (XRF) and isotherms of adsorption and desorption of nitrogen (BET method). The study of the crystallite size was based on the interpretation of x-ray diffractograms obtained and estimated by the method of Halder-Wagner-Scherrer and Langford. An experimental design was made in order to assist in quantifying the influence of synthesis conditions on the response variables. The synthesis parameters evaluated in this study were: pH of the reaction medium (8, 9 and 10), the calcination temperature (combined complexation method EDTA/Citrate 600°C, 800°C and 1000°C), synthesis temperature (hydrothermal method 120°C, 140°C and 160°C), calcination time (combined complexation method EDTA/Citrate - 2, 4 and 6 hours) and time of synthesis (hydrothermal method 6, 15 and 24 hours). By the hydrothermal method was possible to produce mesoporous powders with high purity, with an average crystallite size up to 7 nm, with a surface area of 113.44 m²/g in the form of pellets with irregular morphology. By using the method of combined complexation EDTA/Citrate, mesoporous powders were produced with greater purity, crystallite size up to 22nm and 27.95 m²/g of surface area in the form of pellets with a regular morphology of plaques. In the experimental design was found that the hydrothermal method to all the studied parameters (pH, temperature and time) have significant effect on the crystallite size, while to the combined complexation method EDTA/Citrate, only temperature and time were significant

Utilização de métodos estatísticos multivariados na caracterização do mosaico sucessional em floresta semidecídual

O presente trabalho objetivou verificar a possibilidade da utilização de métodos estatísticos multivariados na caracterização das fases do desenvolvimento do mosaico sucessional de um trecho de floresta estacional semidecidual, através de variáveis estruturais. Foram alocadas parcelas de 10 m x 10 m, em que se procedeu à análise estrutural, ou seja, levantamento fitossociológico acrescido das variáveis Porcentagem de Cobertura (PC), Altura do Dossel (AD) e Cobertura por Lianas (CL). Os métodos estatísticos empregados foram Análise de Componentes Principais e Análise de Agrupamento, mais especificamente Classificação Hierárquica Ascendente. O primeiro componente principal explicou 43,96% da variância total, enquanto o segundo, 25,66%. As variáveis Área Basal (AB), Diâmetro Médio (DM) e Dominância Média (DOM) apresentaram correlações positivas entre si superiores a 0,75, podendo ser DM e DOM consideradas como um grupo de variáveis. As variáveis Número de Indivíduos (NI) e Número de Espécies (NE) apresentaram correlação 0,60, enquanto AD, CL e PC baixas correlações com as demais, indicando a importância da inclusão destas na análise. A classificação hierárquica e a partição dos grupos em quatro foram feitas considerando os dois primeiros eixos fatoriais. Os resultados indicaram dois comportamentos diferenciados: 1) valores baixos para AD e AB: Grupo 1, com valores baixos também para NI, NE e PC (fase de clareira); e Grupo 2, com valores elevados para NI e CL e baixos para DOM e DM (fase de construção); e 2) valores altos para AD e AB: Grupo 3, com valores altos também para NI, NE e PC e valor baixo para CL (fase madura); e Grupo 4, com valores elevados para DOM e DM e mais baixos para CL (fase de degradação). Os métodos estatísticos multivariados permitiram caracterizar as fases do desenvolvimento do mosaico sucessional, através das variáveis estruturais. A forma como foram estimadas as variáveis AD, CL e PC, porém, deve ser aprimorada, assim como é preciso incluir variáveis que discriminem melhor cada fase.

Estudo de técnicas para o tratamento alternativo de efluentes oleosos oriundos da industrialização da castanha de caju

An evaluation project was conducted on the technique of treatment for effluent oil which is the deriving process to improve cashews. During the evaluation the following techniques were developed: advanced processes of humid oxidation, oxidative processes, processes of biological treatment and processes of adsorption. The assays had been carried through in kinetic models, with an evaluation of the quality of the process by means of determining the chemical demand of oxygen (defined as a technique of control by means of comparative study between the available techniques). The results demonstrated that the natural biodegradation of the effluent ones is limited, as result using the present natural flora in the effluent one revealed impracticable for an application in the industrial systems, independent of the evaluation environment (with or without the oxygen presence). The job of specific microorganisms for the oily composite degradation developed the viability technique of this route, the acceptable levels of inclusion in effluent system of treatment of the improvement of the cashew being highly good with reasonable levels of removal of CDO. However, the use combined with other techniques of daily pay-treatment for these effluent ones revealed to still be more efficient for the context of the treatment of effluent and discarding in receiving bodies in acceptable standards for resolution CONAMA 357/2005. While the significant generation of solid residues the process of adsorption with agroindustrial residues (in special the chitosan) is a technical viable alternative, however, when applied only for the treatment of the effluent ones for discarding in bodies of water, the economic viability is harmed and minimized ambient profits. Though, it was proven that if used for ends of I reuse, the viability is equalized and justifies the investments. There was a study of the photochemistry process which have are applicable to the treatment of the effluent ones, having resulted more satisfactory than those gotten for the UV-Peroxide techniques. There was different result on the one waited for the use of catalyses used in the process of Photo. The catalyses contained the mixing oxide base of Cerium and Manganese, incorporated of Potassium promoters this had presented the best results in the decomposition of the involved pollutants. Having itself an agreed form the gotten photochemistry daily paytreatment resulted, then after disinfection with chlorine the characteristics next the portability to the water were guarantee. The job of the humid oxidation presented significant results in the removal of pollutants; however, its high cost alone is made possible for job in projects of reuses, areas of low scarcity and of raised costs with the capitation/acquisition of the water, in special, for use for industrial and potable use. The route with better economic conditions and techniques for the job in the treatment of the effluent ones of the improvement of the cashew possesses the sequence to follow: conventional process of separation water-oil, photochemistry process and finally, the complementary biological treatment
