However, in order to built more realistic models it is necessary to consider the evolution of small density perturbations for explaining the richness of observed structures in the scale of galaxies and clusters of galaxies. The structure formation process was pioneering described by Press and Schechter (PS) in 1974, by means of the galaxy cluster mass function. The PS formalism establishes a Gaussian distribution for the primordial density perturbation field. Besides a serious normalization problem, such an approach does not explain the recent cluster X-ray data, and it is also in disagreement with the most up-to-date computational simulations. In this thesis, we discuss several applications of the nonextensive q-statistics (non-Gaussian), proposed in 1988 by C. Tsallis, with special emphasis in the cosmological process of the large structure formation. Initially, we investigate the statistics of the primordial fluctuation field of the density contrast, since the most recent data from the Wilkinson Microwave Anisotropy Probe (WMAP) indicates a deviation from gaussianity. We assume that such deviations may be described by the nonextensive statistics, because it reduces to the Gaussian distribution in the limit of the free parameter q = 1, thereby allowing a direct comparison with the standard theory. We study its application for a galaxy cluster catalog based on the ROSAT All-Sky Survey (hereafter HIFLUGCS). We conclude that the standard Gaussian model applied to HIFLUGCS does not agree with the most recent data independently obtained by WMAP. Using the nonextensive statistics, we obtain values much more aligned with WMAP results. We also demonstrate that the Burr distribution corrects the normalization problem. The cluster mass function formalism was also investigated in the presence of the dark energy. In this case, constraints over several cosmic parameters was also obtained. The nonextensive statistics was implemented yet in 2 distinct problems: (i) the plasma probe and (ii) in the Bremsstrahlung radiation description (the primary radiation from X-ray clusters); a problem of considerable interest in astrophysics. In another line of development, by using supernova data and the gas mass fraction from galaxy clusters, we discuss a redshift variation of the equation of state parameter, by considering two distinct expansions. An interesting aspect of this work is that the results do not need a prior in the mass parameter, as usually occurs in analyzes involving only supernovae data.Finally, we obtain a new estimate of the Hubble parameter, through a joint analysis involving the Sunyaev-Zeldovich effect (SZE), the X-ray data from galaxy clusters and the baryon acoustic oscillations. We show that the degeneracy of the observational data with respect to the mass parameter is broken when the signature of the baryon acoustic oscillations as given by the Sloan Digital Sky Survey (SDSS) catalog is considered. Our analysis, based on the SZE/X-ray data for a sample of 25 galaxy clusters with triaxial morphology, yields a Hubble parameter in good agreement with the independent studies, provided by the Hubble Space Telescope project and the recent estimates of the WMAP / As recentes observa??es astron?micas indicam que o universo tem curvatura espacial nula, expande aceleradamente e seu conte?do de mat?ria-energia ? composto por cerca de 30% de mat?ria (b?rions + mat?ria escura) e 70% de energia escura, uma componente relativ?stica com press?o negativa. No entanto, para construir modelos ainda mais real?sticos do universo, ? necess?rio considerar a evolu??o de pequenas perturba??es de densidade sob a??o da gravidade, a fim de explicar a riqueza de estruturas observadas na escala de gal?xias e aglomerados de gal?xias. O processo de forma??o de estruturas foi pioneiramente descrito por Press e Schechter (PS) em 1974, atrav?s da fun??o de massa dos aglomerados de gal?xias. O formalismo PS pressup?e uma distribui??o gaussiana para o campo primordial das perturba??es de densidade. Al?m de um s?rio problema de normaliza??o, tal abordagem n?o explica os atuais dados de raios-X dos aglomerados, e est? em desacordo com as modernas simula??es computacionais. Nesta tese, discutimos diversas aplica??es da q-estat?stica n?o extensiva (n?o gaussiana) proposta em 1988 por C. Tsallis, com especial ?nfase para o processo cosmol?gico de forma??o das grandes estruturas. Inicialmente, investigamos a estat?stica do campo de flutua??es dos contrastes de densidade primordiais, j? que os dados mais recentes do Wilkinson Microwave Anisotropy Probe (WMAP) indicam um desvio da gaussianidade. Assumimos que tais desvios podem ser descritos pela estat?stica n?o extensiva, pois ela se reduz ? distribui??o gaussiana, no limite do par?metro livre q = 1, o que permite uma compara??o direta com a teoria padr?o. Estudamos sua aplica??o para um cat?logo de aglomerados gal?ticos baseado no ROSAT All-Sky Survey (doravante nomeado como HIFLUGCS). Concluimos que o modelo gaussiano padr?o aplicado ao HIFLUGCS n?o corrobora os dados mais recentes obtidos de forma independente pelo WMAP. Utilizando a estat?stica n?o extensiva obtemos valores bem mais compat?veis com os resultados do WMAP. Demonstramos tamb?m que a distribui??o de Burr corrige o problema da normaliza??o. O formalismo da fun??o de massa dos aglomerados foi tamb?m investigado na presen?a da energia escura. Neste caso, limites sobre os mais diversos par?metros c?smicos foram tamb?m obtidos. A estat?stica n?o extensiva foi ainda implementada em 2 problemas distintos: (i) a sonda de plasma e (ii) na descri??o da radia??o de Bremsstrahlung (a radia??o prim?ria dos aglomerados de raio-X); um problema de consider?vel interesse astrof?sico. Numa outra linha de desenvolvimento, utilizando dados de supernovas e fra??o de massa do g?s em aglomerados, discutimos a varia??o do par?metro da equa??o de estado da energia escura, considerando 2 expans?es distintas. Um aspecto interessante desse trabalho ? que os resultados n?o necessitam de um prior no par?metro de massa, como ocorre usualmente nas an?lises envolvendo apenas os dados de supernovas. Finalmente, fazemos uma nova estimativa do par?metro de Hubble, atrav?s de uma an?lise conjunta envolvendo o efeito Sunyaev-Zeldovich (SZE), o espectro de raios-X de aglomerados e as oscila??es ac?sticas dos b?rions. Mostramos que a degeneresc?ncia dos dados observacionais em rela??o a ? quebrada quando incluimos a assinatura das oscila??es ac?sticas dos b?rions, dada pelo cat?logo do Sloan Digital Sky Survey (SDSS). Nossa an?lise, baseada nos dados de SZE/raios-X para uma amostra de 25 aglomerados com morfologia triaxial, deriva um par?metro de Hubble em bom acordo com estudos independentes do projeto Hubble Space Telescope e as recentes estimativas do WMAP

However, there is still a scarcity of studies with well-controlled methods to investigate the possible effects of Yoga practice. In this study, we investigated the effects of regular Yoga practice, based on Yoga postures (asanas), breathing techniques, and meditation exercises, on memory and physiologic and psychological parameters related to quality of life. There were significant improvements on performance tasks of short term memory and long term memory. We also observed significant beneficial effects on psychological and physiological parameters such as mood, anxiety, depression, stress, and modulation of the autonomic nervous system in Yoga practitioners group compared to the conventional physical exercises group. The results suggest the possible influences of stress, emotional state and mental training on cognitive effects of yoga practice. Our results support the indication of practice of Yoga for the treatment or prevention of stress, psychological disorders and their possible cognitive consequences / T?cnicas de controle de mente e do corpo parecem beneficiar o organismo de forma geral e em particular a cogni??o, porque envolvem pr?tica de aten??o plena.

Foi analisada uma amostra de 38 crian?as do sexo masculino praticantes de futebol divididos em dois grupos: 20 no grupo do treinamento neuromuscular integrativo (GINT) e 18 no grupo controle (GC). Em seguida, foi aplicado o question?rio socioecon?mico para os pais, n?vel de atividade f?sica di?ria para os integrantes do estudo e a avalia??o da predi??o da idade ?ssea (CABRAL, 2013). Para determinar o efeito do INT no DM foi realizado uma bateria de testes f?sicos para a avalia??o do equil?brio, flexibilidade, agilidade, velocidade e pot?ncia anaer?bica de membros inferiores em tr?s momentos, antes (pr?) durante (6 semanas) e ap?s (12 semanas) de realiza??o do INT.. O INT foi realizado duas vezes por semana, 20 minutos iniciais de cada treino e constou de cinco exerc?cios voltados para aptid?o f?sica relacionada ? sa?de e ao desempenho. para verificar a homogeneidade das vari?veis do estudo entre os grupos, aplicou-se teste t de Student n?o pareado e o teste de Mann-Whitney. Para observar o efeito do tempo e a intera??o do treinamento no desempenho motor entre os dois grupos foram utilizadas a ANOVA mista de medidas repetidas, al?m do teste Post- Hoc com ajuste de Bonferroni, com intuito de identificar poss?veis diferen?as. Desta forma, para a vari?vel equil?brio ocorreu diferen?a significativa no efeito do tempo para o grupo INT, F(1,5;55,3) =5.865, p= 0.009, ??= 0.14, nos momentos pr? para 12 semanas do GINT (p < 0.001, d = 0,74) e do momento seis semanas para 12 semanas (p= 0.005, d = 0,35). Bem como, observou-se o efeito da intera??o, F(1,5;55,3) = 6.536, p=0.006, ??= 0.14, entre o GINT e GC no momento 12 semanas. Para a flexibilidade encontrou-se melhoria significativa no efeito do tempo, F(1,2;45,5) = 11.620, p= 0.001, ??= 0,24, no GINT entre os momentos pr? para seis semanas (p= 0.02; d= 0,48) pr? para 12 semanas (p < 0.001; d = 0,75) e entre os momentos seis para 12 semanas (p= 0.003; d= 0,25). Na agilidade verificou-se o efeito do tempo, F (2,72) = 7.332, p= 0.001, ??= 0,16, no grupo interven??o somente entre os momentos pr? para 12 semanas (p = 0.02). Em rela??o a vari?vel velocidade revelou-se n?o haver efeito do tempo nos grupos, (F (1,5;54,4)= 2.422, p= 0.112, ??= 0,06), como tamb?m n?o houve intera??o dos grupos nos tempos, (F (1,5;54,4)= 0.059, p= 0.898, ??= 0,002).Para a pot?ncia anaer?bica de membros inferiores houve intera??o entre os grupos, F(1,2;44,8)= 6.644, p= 0.009, ??= 0.15, por?m o teste post hoc com ajuste de Bonferroni n?o identificou em qual tempo havia intera??o. Quando analisado a m?dia ?% entre os grupos nas vari?veis motoras, algumas vari?veis tiveram melhorias significativas nos momentos pr? para 12 semanas, sendo apresentados os seguintes resultados: equil?brio (w=62,0; p=0,005), flexibilidade (w=97,0; p=0,015) e pot?ncia anaer?bica de membros inferiores (w=94,0; p=0,012). A adi??o do INT ao treinamento sistem?tico aplicado a crian?as teve influ?ncia direta no desempenho motor na maioria das capacidades f?sicas no per?odo de 12 semanas, a t?cnica dos exerc?cios integrais, o volume e intensidade adequados forneceram adapta??es de natureza neuromuscular na qual possibilitou uma melhora na mec?nica do movimento. / The present study aims to evaluate the effects of integrative neuromuscular training (INT) on motor performance in children between 06 and 10 years old. A sample of 38 male soccer players were divided into two groups: 20 in the integrative neuromuscular training group (GINT), age: 8.2 ? 1.2 years; body mass: 28.4 ? 6.4 kg; height: 1.3 ? 0.1 m. In addition to the 18 for the control group (GC), age: 8.5 ? 1.3 years; body mass: 32.8 ? 8.9 kg; height: 1.3 ? 0.1 m. The socioeconomic questionnaire was then applied to the parents, daily physical activity level for the study participants, as well as to evaluate the prediction of bone age (CABRAL, 2013) through anthropometric measurements. To determine the effect of INT on DM, a battery of physical tests was performed to evaluate the balance, flexibility, agility, speed and anaerobic power of the lower limbs at three moments, before (during) (6 weeks) and after (12 weeks ) of INT. The INT was performed twice a week, 20 minutes after each training, and consisted of five exercises aimed at physical fitness related to health and performance. To verify the homogeneity of the study variables between the groups, we applied unpaired Student's t test and the Mann-Whitney test. To observe the effect of time and interaction of training on motor performance between the two groups, the mixed ANOVA of repeated measures was used, in addition to the Post-Hoc test with Bonferroni adjustment, in order to identify possible differences. Thus, for the balance variable, there was a significant difference in the time effect for the INT group, F (1.5; 55.3) = 5.865, p = 0.009, ?? = 0.14, at the pre-12 weeks GINT <0.001, d = 0.74) and from the moment 6 weeks to 12 weeks (p = 0.005, d = 0.35). As well, the interaction effect, F (1,5; 55,3) = 6,536, p = 0.006, ?? = 0.14, was observed between the GINT and GC at the moment 12 weeks. For flexibility, significant improvement in the time effect was found, F (1.2; 45.5) = 11.620, p = 0.001, ?? = 0.24, in GINT between the pre-six and six-week periods (p = 0.02; d = 0.48) and pre-12 weeks (p <0.001; d = 0.75), and between times six and 12 weeks (p = 0.003; d = 0.25). In the agility, the effect of time was found, F (2.72) = 7.332, p = 0.001, ?? = 0.16, in the intervention group only between the pre-12 weeks (p = 0.02). In relation to the velocity variable, there was no effect of time in the groups, (F (1,5; 54,4) = 2,422, p = 0.112, ?? = 0,06), as well as there was no interaction of the groups in the times , (F (1.5; 54.4) = 0.059, p = 0.898, ?? = 0.002). For the anaerobic power of lower limbs, there was interaction between the groups, F (1,2; 44,8) = 6,644, p = 0.009, ?? = 0.15, but the post hoc test with Bonferroni adjustment did not identify at what time there was interaction. When the mean ?% between the groups in the motor variables was analyzed, some variables had significant improvements in the moments pre-12 weeks, and the following results were presented: balance (w = 62.0, p = 0.005), flexibility 0, p = 0.015) and anaerobic power of lower limbs (w = 94.0, p = 0.012). The addition of INT to the systematic training applied to children had a direct influence on motor performance in the majority of physical abilities over the 12 week period, the technique of the integral exercises, the adequate volume and intensity provided neuromuscular adaptations in which an improvement in mechanics of movement

Para o desenvolvimento desta pesquisa foi realizado um estudo observacional, de car?ter descritivo, transversal, com uma abordagem quantitativa. Participaram dessa pesquisa doze jovens jogadores de futebol de campo do sexo masculino, pertencentes a uma mesma equipe (idade: 16,6?0,51 anos; estatura: 175?8cm; massa corporal: 65?7,9kg), da categoria sub 17, que jogaram quatro jogos competitivos (J1, J2, J3 e J4) com 24 horas de intervalos entre os jogos. Para quantifica??o da imunoglobulina A salivar (S-IgA), esse foi expresso como concentra??o absoluta de IgA (s-IgAabs), taxa de secre??o de IgA (s-IgAtaxa) e fluxo salivar (FS). Para a carga interna competitiva, a mesma foi determinada pela Percep??o Subjetiva de Esfor?o da sess?o (PSE). O tempo de jogo de cada atleta participante durante os quatro jogos foi registado para determinar a carga interna competitiva pela PSE da sess?o, assim como a monotonia e o esfor?o competitivo. Os dados est?o apresentados em de m?dia e desvio padr?o. Verificou-se a normalidade das vari?veis dependentes com o teste de Shapiro Wilk (p > 0,05). Utilizou-se o teste t de Student para an?lise do IgA salivar e taxa de fluxo salivar no primeiro e no quinto jogo da competi??o. ANOVA de medidas repetidas comparou a PSE da sess?o e a carga interna ao longo dos jogos, o post hoc de Bonferroni foi utilizado para identificar as diferen?as entre as medidas. O ?d? de Cohen foi utilizado para estimar a magnitudes das diferen?as (tamanho do efeito - TE) entre todas as compara??es. Foi utilizado o coeficiente de correla??o de Spearman para analisar a correla??o entre o ?ndice de monotonia e o esfor?o competitivo com o SIgA absoluto. Os valores de PSE da sess?o n?o foram diferentes ao longo dos jogos F(4,33) = 1,680, p < 0,1902, ??: 0,72. Os valores de carga interna diferiram ao longo da competi??o F(4,33) = 6,299, p = 0,001, ??:0,66. Sendo observado diferen?as nos jogos 2 e 4 em compara??o com o 3 (p<0,05). As concentra??es de IgA salivar absolutos e relativos diminu?ram ap?s a competi??o quando comparado com o momento pr? competi??o (IgA absoluto t (11) = 2,744 p = 0,01 e IgA relativo (t (11) = 2,744, p = 0,04). Diferentemente, a taxa de fluxo salivar pr? jogos foi semelhante ao momento p?s t (11) = 0,1010, p = 0,921). A associa??o entre os valores do delta de varia??o do IgA salivar absoluto com a monotonia da competi??o, verificou-se que houve uma alta correla??o significante com um (r = 0,62: p=0,031). Al?m disso foi encontrada uma correla??o quase significante entre o esfor?o competitivo e o delta de varia??o do IgA absoluto (r = 0,57: p=0,051). Os dados demonstraram que jogos competitivos em um calend?rio congestionado diminu?ram a imunidade da mucosa em respostas ao aumento da carga interna percebida. / The purpose of this study was to investigate the effect of competitive games on a congested schedules on mucosal immunity in young soccer players. For the development of this research, an observational, descriptive, cross-sectional study was conducted with a quantitative approach. Twelve young male soccer players from the same team (age: 16.6 ? 0.51 years, height: 175 ? 8cm, body mass: 65 ? 7.9kg), from the sub category 17, who played four competitive games (J1, J2, J3 and J4) with 24-hour breaks between games. For quantification of salivary immunoglobulin A (S-IgA), this was expressed as absolute concentration of IgA (s-IgAabs), IgA secretion rate (s-IgAtaxa) and salivary flow (FS). For the competitive internal load, it was determined by the Subjective Effort Perception of the session (PSE). The playing time of each participating athlete during the four games was recorded to determine the competitive internal load by the PSE of the session, as well as the monotony and the competitive effort. Data are presented as mean and standard deviation. Normality of the dependent variables was verified with the Shapiro Wilk test (p> 0.05). Student's t-test was used to analyze salivary IgA and salivary flow rate in the first and fifth games of the competition. Repeated measures ANOVA compared the session PSE and the internal load throughout the games, the Bonferroni post hoc was used to identify the differences between the measures. Cohen's "d" was used to estimate magnitudes of differences (effect size - TE) among all comparisons. The Spearman correlation coefficient was used to analyze the correlation between the monotony index and the competitive effort with the absolute SIgA. The PSE values of the session were not different throughout the games F (4,33) = 1,680, p <0,1902, ??: 0,72. The internal load values differed throughout the competition F (4,33) = 6.299, p = 0.001, ??: 0.66. Differences were observed in games 2 and 4 compared to 3 (p <0.05). Absolute and relative salivary IgA concentrations decreased after competition when compared to the pre-competition time (absolute IgA t (11) = 2.744 p = 0.01 and relative IgA (t (11) = 2.744, p = 0.04) The salivary flow rate pre-set was similar to the post-t (11) = 0.1010, p = 0.921). The association between the values of the absolute salivary IgA variation delta and the monotony of the competition showed that there was a significant high correlation with one (r = 0.62: p = 0.031). In addition, a quasi-significant correlation was found between the competitive effort and the absolute IgA variation delta (r = 0.57: p = 0.051). The data demonstrated that competitive games in a congested schedules decreased mucosal immunity in response to increased internal perceived load.

From an ethnographic research, I have searched to do a description of some musical activities, which have been developed in the downtown, promoting, as well, reflections about to be independent, and arguing the different implications, which can be attributed to the category with different problematic issues. Also, it has been analysed processes that involve a musical digitalisation promoted by the advent of new technologies in the musical ambient, realising, therefore, which effects are inferred about the creation, production, recording, dissemination, distribution and sharing methods about music by using available internet tools, such as social network, streaming and music download services. By the way, recognising how such mechanisms are achieved by the interlocutors, i have described various uses employed by agents of band members, music producers, sound technicians, cultural members and other professionals involved in musical projects. Finally, I have argued about different musical places in the downtown with the goal of constructing a description of some events that clarify the ?independent individual? in Natal.

As reflex?es que nortearam a investiga??o est?o fundamentadas em autores que abordam os aspectos referentes ? criatividade em geral, o indiv?duo criativo, o processo de cria??o (NACHMANOVICTH, 1993; GARDNER, 1996) ? incluindo o processo criativo musical ?, as motiva??es envolvidas nesse processo (REEVE, 2006), e a forma??o e atua??o pedag?gica do professor criativo (ABRAH?O, 2015; SCHAFER, 1991). As concep??es constru?das a partir da fundamenta??o te?rica baseiam-se na ideia de que, para criar, o indiv?duo necessita ter o dom?nio sobre os elementos a serem usados na cria??o, assim como a viv?ncia de experi?ncias que lhe subsidiam na a??o de gerar novos produtos, e o conhecimento sobre o processo criativo, que lhe permite persistir na trajet?ria at? que chegue ao produto final. Sobre a quest?o pedag?gico-musical especificamente, as ideias que fundamentam a investiga??o s?o aquelas que tratam a criatividade como um elemento fundamental para o exerc?cio da profiss?o. O m?todo de pesquisa escolhido foi o estudo de caso, utilizando como ferramentas de coleta de dados o question?rio, a observa??o direta e a entrevista semiestruturada. A an?lise dos dados se deu, primeiramente, de forma quantitativa e qualitativa, quando analisadas as respostas colhidas a partir do question?rio. Posteriormente, a abordagem qualitativa se sobrep?s na an?lise das etapas seguintes, quando os dados foram organizados em tr?s categorias: 1. As concep??es dos professores; 2. As caracter?sticas dos professores; e 3. As pr?ticas criativas realizadas. Os resultados apresentam alguns fatores relevantes sobre o processo criativo do professor, a fim de possibilitar a reflex?o de que todos possuem a condi??o e a possibilidade de criar, desde que se permita e possua o conhecimento sobre o processo criativo (NACHMANOVICTH, 1993). Al?m disso, as reflex?es realizadas a partir da rela??o entre a abordagem dos autores te?ricos e os dados emp?ricos coletados, visam promover uma inquieta??o no que tange a forma??o inicial dos educadores musicais, e a sua posterior atua??o pedag?gica. / The present work had the purpose of understanding the conceptions and practices that characterizes the pedagogical action of teachers that has the creativity as a process and aim of their musical education proposal in Natal/RN school context. The reflections that guided us are based on authors who deal with aspects related to creativity in general, the creative individual, the creative process (NACHMANOVICTH, 1993; GARDNER, 1996) - including the creative musical process - the motivations involved in this process (REEVE, 2006), and the training and pedagogical performance of the creative teacher (ABRAH?O, 2015; SCHAFER, 1991). Our concepts, built from the theoretical background, are based on the idea that, to create properly, the individual needs to have control over the elements to be used in creation, as well as the grasp of experiences that support him in the action of generating new products, and knowledge about the creative process, which allows it to persist in the path until it reaches the final product. On the pedagogical-musical question specifically, the ideas the investigation are based upon are those that treat the creativity as a basilar element for the exercise of the profession. The research method chosen was the case study, using as a data collection tool the questionnaire, direct observation and semi-structured interview. Data were analyzed first, in a quantitative and qualitative way, when the answers collected from the questionnaire were analyzed. Afterwards, the qualitative approach was set before in the analysis of the following stages, when the data were organized into three categories: 1. The conceptions of teachers; 2. The characteristics of teachers; and 3. The creative practices. The results present some relevant factors on the creative process of the teacher that allow us to reflect that all have the condition and the possibility of creating, if the knowledge about the creative process is endowed and permitted (NACHMANOVICTH, 1993). Furthermore, the reflections based on the relationship between the theoretical authors' approach and the empirical data collected, drive us to prosecute a concern about the initial formation of musical educators and their subsequent pedagogical performance.

Nesse contexto, considerando as bandas de m?sica como um dos espa?os onde se articulam saberes para a atua??o e forma??o do professor de m?sica, este estudo apresenta uma pesquisa realizada com tr?s maestros que atuam respectivamente em tr?s bandas de m?sica da regi?o do Alto Oeste Potiguar, com o objetivo de conhecer e refletir sobre quais saberes docentes est?o presentes na pr?tica desses maestros, como se constituem e de que forma cada maestro articula esses saberes durante a sua pr?tica pedag?gico-musical. Os estudos de Maurice Tardif (2014), Le?o e Carvalho (2016), Gauthier (2013), entre outros, em di?logo com outros autores da educa??o musical sobre o tema, fundamentam teoricamente o estudo. A metodologia utilizada tem uma abordagem qualitativa, em que foi escolhido como m?todo de pesquisa, o estudo multicaso. Os dados foram colhidos por meio de entrevistas semiestruturadas e observa??es participantes nos ensaios. Foram selecionados tr?s maestros com perfis de forma??o distintos, sendo um bacharel, um licenciado e um autodidata, atuantes, cada um, em uma das bandas de m?sica do Alto Oeste Potiguar. Foi descrito o contexto de atua??o de cada um deles e, a partir da an?lise das entrevistas, foram destacadas 06 (seis) categorias para an?lise: saberes musicais; rela??es interpessoais; experi?ncia com performance de mais de um instrumento musical; import?ncia das iniciativas autodidatas; experi?ncia em diferentes grupos musicais; e experi?ncia de lideran?a de grupos musicais. Ap?s a an?lises dos dados, o estudo indica uma reflex?o sobre a import?ncia de se propor uma forma??o inicial que contribua com a forma??o de profissionais para atuar no contexto das bandas de m?sica, tendo em vista que s?o espa?os bastante s?lidos de atua??o profissional e poder?o contribuir para uma reflex?o sobre os saberes necess?rios ao professor de m?sica para atuar nesse espa?o de ensino. A partir do exposto foi poss?vel afirmar que os maestros aprendem tamb?m durante o fazer pedag?gico-musical, em que a partir da intera??o com os alunos da banda, bem como com seus pares e atrav?s de experi?ncias nos diversos contextos profissionais pelos quais passaram, puderam adquirir saberes e mobiliz?-los para o desenvolvimento de um processo de ensino-aprendizagem musical dentro de cada banda de m?sica. / The studies on the knowledges that are acquired by teachers in formation and how these knowledges are articulated in the teaching performance, has been configured as a relevant subject in the debates about education in the contemporaneity. In this context, considering the music bands as one of the spaces where they articulate knowledge for the performance and training of the music teacher this study presents a research carried out with three conductors, respectively, in three bands from the region of the Upper West Potiguar, with the objective of knowing and reflecting on the teacher's knowledge in the practice of these teachers, how they are constituted and how each teacher articulates these knowledge during their pedagogical-musical practice. The studies of Maurice Tardif (2014), Le?o e Carvalho (2016), Gauthier (2013), and others, in dialogue with other authors of musical education on the subject, theoretically base the study. The methodology used has a qualitative approach, in which was chosen as research method, the multicaso study. The data were collected through semi-structured interviews and participant observations on essays. Three conductors with distinct training profiles were selected, being a bachelor, a licensee and a self-taught, each one of them in one of the bands of music of the Upper West Potiguar. It was described the context of action of each of them and, from the analysis of the interviews, six (6) categories were highlighted for analysis: musical knowledge; interpersonal relationships; experience with performance of more than one musical instrument; importance of self-taught initiatives; experience in different musical groups; and leadership experience of musical groups. After analyzing the data, the study indicates a reflection on the importance of proposing an initial training that contributes to the training of professionals to act in the context of the music bands, considering that they are very solid spaces of professional performance and may contribute to a reflection on the knowledge needed by the music teacher to work in this teaching space. From the above it was possible to affirm that the teachers also learn during the pedagogical-musical fase, in which from the interaction with the students of the band as well as with their peers and through experiences in the different professional contexts through which they passed were able to acquire knowledge and mobilize them for the development of a musical teaching-learning process within each music band.

To achieve this goal a survey was conducted with the following specific objectives: determine general aspects about the cultural and professional training of the active teacher at SESC Cidad?o; understand how the knowledge acquired in the "formal" training of the teacher has subsidized his pedagogical action in the social project; identify and analyze the professional knowledge that sustain the work of this teacher in the SESC Cidad?o project. The theoretical referential is based on studies of teaching knowledge proposed by Tardif (2014) and other studies in the field of Education and Musical Education addressed to this theme. At the investigation was used the case study methodology with the main data collection instruments consisting of direct observation, semi-structured interviews, document research and bibliographical studies. The data were organized and analyzed qualitatively with the help of Atlas.ti software. The results show that the teaching knowledge of the music teacher was constituted throughout his educational and musical experience, as a participant of social projects, and through professional experience as music teacher of the conservatory and SESC Cidad?o project. Moreover, compose his range of knowledge a degree course in Music and a specialization course in Music Therapy. His teaching knowledge is articulated in different ways considering, the way he deals with children, adolescents and young people from the social project, to the choices of how to conduct his work in music activities.

O alvo estudado ? um plug conhecido como S?o Jo?o, intrusivo em rochas sedimentares da borda sul da Bacia Potiguar, regi?o setentrional do Rio Grande do Norte. Com uma ?rea aproximada de 0,5 km?, este plug ? um dos diversos corpos ?gneos constituintes do Magmatismo Macau (50-7 Ma). Os arenitos e calc?rios pr?ximos ao corpo subvulc?nico sofreram modifica??es mineral?gicas significativas por efeito termal. Utilizamos dados magn?ticos aerolevantados do Projeto Bacia Potiguar e aquisi??es terrestres, que resultaram em 5698 leituras com o magnet?metro de campo total e 128 esta??es gravim?tricas com o grav?metro CG5. O mapa das derivadas verticais do campo magn?tico an?malo dos dados a?reos contextualizou regionalmente a geologia e geof?sica da Bacia Potiguar, enquanto que os dados magn?ticos e gravim?tricos terrestres detalharam o plug S?o Jo?o e foram utilizados para as modelagens. Foram realizadas medidas de susceptibilidade magn?tica e densidade em amostras de rochas metam?rficas (buchitos), ?gneas (diab?sio) e sedimentares (arenito e calc?rio). Tais medidas auxiliaram na constru??o de modelos 2D e 3D, revelando a arquitetura interna do plug S?o Jo?o, cujas profundidades chegam a cerca de 400 m. O modelo gravim?trico apresenta uma geometria no formato de lop?lito, com uma regi?o na parte nordeste do corpo apresentando maiores contrastes de densidade. Tal regi?o ? tamb?m observada no modelo magn?tico, com altos contrastes de susceptibilidade magn?tica. M?ximos gravim?tricos pr?ximos ao plug indicam tr?s regi?es com contrastes de densidade positivos, que podem ser corpos ?gneos sem express?o em superf?cie. / This dissertation presents a geophysical study of a Cenozoic basic intrusion, involving steps of acquisition, processing, and 2D and 3D modeling of terrestrial magnetic and gravity data. The target studied is a plug known as S?o Jo?o, located in the southern border of the Potiguar Basin (NE Brazil). This plug has an area of approximately 0.5 km? and was formed by magmatism Macau. Sandstones and limestones near the hipoabissal body suffered metamorphization with significant thermal changes. We use airborne magnetic data named Potiguar Basin Project and terrestrial acquisition, which resulted in 5698 readings with the total field magnetometer and 128 gravity stations with CG5 gravimeter. The map of vertical derivative of the total magnetic intensity anomalies from the airborne data contextualized regionally the geology and geophysics of the Potiguar Basin, while the terrestrial magnetic and gravimetric data detailed the plug S?o Jo?o and were used for the modeling. Magnetic susceptibility and density were measured in metamorphic (buchites) igneous (diabase) and sedimentary (sandstone and limestone) rock samples. Such measures help to constrain the 2D and 3D modeling, which reveal the internal architecture of the S?o Jo?o plug, whose maximum depths reach 400 m. The gravity model of the plug shows a lopolith shape, with a region in the northeastern part of the body having higher density contrast. This region is also observed in the magnetic model with high contrast of magnetic susceptibility. Gravity highs closer to S?o Jo?o plug indicate three regions with high density contrasts, which probably are igneous bodies with no surface expression.

A dan?a potencializa a expressividade do corpo, apresentando-se como uma arte completa, de uma beleza singular. Em primeiro, h? uma descri??o sobre a tradi??o do Araruna considerando a liga??o entre as dan?as europeias, as festas aristocr?ticas da Modernidade e a pr?pria historicidade dos corpos brincantes. Atrelado a isso, ? realizada uma discuss?o sobre a mem?ria do corpo e da Cultura de Movimento do Araruna em Natal/RN. Em segundo, ? evidenciado todo o universo simb?lico existente nos objetos c?nicos e nas letras das m?sicas, que desvelam rela??es entre corpo, cultura, natureza, ludicidade e sexualidade. Tais dimens?es constituem for?as profundas que integram e potencializam a exist?ncia humana. Em terceiro, s?o apresentadas algumas proposi??es est?ticas para a Educa??o F?sica, buscando mobilizar outras reflex?es que intensifiquem a valoriza??o da beleza do dan?ar e celebrar a tradi??o. Por fim, s?o trazidas indaga??es que possam contribuir para a feitura de novas rela??es est?ticas entre a Educa??o F?sica, a dan?a e o corpo. / We situate the Araruna Group in the world lived of Merleau-Ponty?s phenomenology in order to understand it through the method of the network of meanings that was built through photos, videos, interviews with players and also the symbols contained in the props: music, hat, fan, makeup, colors and costumes. Dance enhances the expressiveness of the body, presenting itself as a complete art of singular beauty. First, there is a description of the tradition of Araruna considering the link between European dances, the aristocratic parties of Modernity and the historicity of the players bodies. Coupled to this, it is held a discussion on the memory of the body and Araruna Movement of Culture in Natal/RN. Second, it is highlighted all existing symbolic universe in props and lyrics of the songs, that reveal relationships between body, culture, nature, playfulness and sexuality. Such dimensions are deep forces that integrate and enhance human life. Third, some aesthetic propositions for Physical Education, seeking to mobilize other reflections that intensify the appreciation of the beauty of dance and celebrate tradition, are presented. Finally, are brought some questions that can contribute to the making of new aesthetic relationships between physical education, dance and body.
