A Multitechnique Study of Structure and Dynamics of Polyfluorene Cast Films and the Influence on Their Photoluminescence

This article describes the microstructure and dynamics in the solid state of polyfluorene-based polymers, poly(9,)-dioctylfluorenyl-2,7-diyl) (PFO), a semicrystalline polymer, and poly [(9,9-dioctyl- 2,7-divinylene-fluorenylene)-alt-co-{2-methoxy-5-(2-ethyl-hexyloxy)- 1,4-phenylene vinylene}, a copolymer with mesomorphic phase properties. These Structures were determined by wide-angle X-ray scattering (WAXS) measurements, Assuming a packing model for the copolymer structure, where the planes of the phenyl rings are stacked and separated by an average distance of similar to 4.5 angstrom and laterally spaced by about similar to 16 angstrom, we followed the evolution of these distances as a function of temperature using WAXS and associated the changes observed to the polymer relaxation processes identified by dynamical mechanical thermal analysis. Specific molecular motions were studied by solid-state nuclear magnetic resonance. The onset of the side-chain motion at about 213 K (beta-relaxation) produced a small increase in the lateral spacing and in the stacking distance of the phenyl rings in them aggregated Structures, Besides, at about 383 K (alpha-relaxation) there occurs a significant increase in the amplitude of the torsion motion in the backbone, producing a greater increase in the stacking distance of the phenyl rings. Similar results were observed in the semicrystalline phase of PFO, but in this case the presence of the crystalline structure affects considerably the overall dynamics, which tends to be more hindered. Put together, Our data explain many features of the temperature dependence of the photoluminescence of these two polymers.

Temperature dependence of molecular dynamics and supramolecular aggregation in MEH-PPV films: A solid-state NMR, X-ray and fluorescence spectroscopy study

This article presents an investigation of the temperature induced modification in the microstructure and dynamics of poly[2-methoxy-5-(2`-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV) cast films using Wide-Angle X-ray Scattering (WAXS), solid-state Nuclear Magnetic Resonance (NMR), and Fluorescence Spectroscopy (PL). MEH-PPV chain motions were characterized as a function of temperature by NMR. The results indicated that the solvent used to cast the films influences the activation energy of the side-chain motions. This was concluded from the comparison of the activation energy of the toluene cast film, E(a) = (54 +/- 8) kJ/mol, and chloroform cast film, E(a) = (69 +/- 5) kJ/mol, and could be attributed to the higher side-chain packing provided by chloroform, that preferentially solvates the side chain in contrast to toluene that solvates mainly the backbone. Concerning the backbone mobility, it was observed that the torsional motions in the MEH-PPV have average amplitude of similar to 10 degrees at 300 K, which was found to be independent of the solvent used to cast the films. In order to correlate the molecular dynamics processes with the changes in the microstructure of the polymer, in situ WAXS experiments as a function of temperature were performed and revealed that the interchain spacing in the MEH-PPV molecular aggregates increases as a function of temperature, particularly at temperatures where molecular relaxations occur. It was also observed that the WAXS peak associated with the bilayer spacing becomes narrower and its intensity increases whereas the peak associated with the inter-backbone planes reduces its intensity for higher temperatures. This last result Could be interpreted as a decrease in the number of aggregates and the reduction of the interchain species during the MEH-PPV relaxation processes. These WAXS results were correlated with PL spectra modifications observed upon temperature treatments. (C) 2008 Elsevier Ltd. All rights reserved.

Seguimento clinoceletrográfico de criançcas e adolescentes com crise epiléptica única não-provocada

Os fenômenos convulsivos despertaram o interesse de estudiosos e pensadores já na Antigüidade, quando aspectos mágicos e sobrenaturais eram a eles associados. No século XIX foram lançadas as bases dos conceitos atuais sobre a desestruturação funcional cerebral na epilepsia, e Berger, em 1929, marcou definitivamente a história com a descoberta dos ritmos cerebrais. Crise epiléptica e epilepsia não são sinônimos, já que o último termo refere-se a crises recorrentes espontâneas. Ela costuma iniciar na infância, daí a preocupação com o risco de repetição do primeiro episódio e com a decisão de instituir tratamento medicamentoso. Fatores prognósticos são apontados, mas não há consenso. No Brasil existem poucas pesquisas nesta linha, tanto de prevalência da epilepsia como de fatores envolvidos na recorrência de crises. Este estudo teve como objetivo geral avaliar aspectos clinicoeletrográficos capazes de auxiliar no prognóstico e no manejo da epilepsia da criança e do adolescente. Foram objetivos específicos determinar a incidência de crise epiléptica não provocada recorrente; identificar fatores remotos implicados na ocorrência de crise epiléptica; relacionar tipo de crise com achados eletrencefalográficos; relacionar tipo de crise, duração da crise, estado vigília/sono no momento da crise e achados eletrencefalográficos com possibilidade de recorrência; e identificar os fatores de risco para epilepsia. Foram acompanhados 109 pacientes com idades entre 1 mês e 16 anos, com primeira crise não-provocada, em média por 24 meses, a intervalos trimestrais, no Hospital de Clínicas de Porto Alegre (HCPA). Foram realizados eletrencefalogramas (EEG) após a primeira crise; depois, solicitados anualmente. Não foram incluídos casos com epilepsia ou síndrome epiléptica bem definida, ou que fizeram uso prévio de drogas antiepilépticas. A média de idade foi 6 anos, com predomínio da faixa etária de 6 a 12 anos. Setenta eram meninos e 39, meninas. Os indivíduos brancos eram 92, e os não-brancos, 17. O nível de escolaridade dos casos esteve de acordo com a distribuição da idade e, entre os responsáveis, predominaram 8 anos de escolaridade. Foi possível concluir que as crises únicas não-provocadas mais freqüentes foram generalizadas, e sem predomínio significativo do tipo de EEG. A incidência de crise não-provocada recorrente foi 51,4%. História de intercorrências pré-natais maternas aumentou em 2 vezes o risco de repetição de crises. Via de nascimento, escore de Apgar no 5º minuto, relação peso ao nascer/idade gestacional, intercorrências no período pós-natal imediato e desenvolvimento neuropsicomotor não tiveram influência na recorrência. História familiar de crises mostrou tendência à significância estatística para repetição dos episódios, com risco de 1,7. Não foi encontrada associação entre tipo de crise e achado eletrencefalográfico. A maioria das crises foi de curta duração (até 5 minutos), mas este dado não esteve relacionado com a recorrência. Estado de vigília teve efeito protetor na recorrência. Se a primeira crise foi parcial, o risco de repetição foi 1,62, com tendência à significância. Quando o primeiro EEG foi alterado, houve relação significativa com primeira crise tanto generalizada como parcial. O primeiro EEG com alterações paroxísticas focais apontou risco de repetição de 2,90. Quando as variáveis envolvidas na repetição de crises foram ajustadas pelo modelo de regressão de Cox, EEG alterado mostrou risco de 2,48, com riscos acumulados de 50%, 60%, 62% e 68%; com EEG normal, os riscos foram 26%, 32%, 34% e 36% em 6, 12, 18 e 24 meses respectivamente.

Avaliação de cultivares de melancia na Depressão Central do Rio Grande do Sul

O objetivo do presente trabalho conduzido na Estação Experimental Agronômica da Universidade Federal do Rio Grande do Sul em Eldorado do Sul, RS, em um solo Podzólico Vermelho Amarelo, foi avaliar nove cultivares de melancia (Citrullus lanatus) buscando identificar cultivares de melhor adaptação à região, possibilitando o cultivo em anos sucessivos na mesma área, pois os produtores devido a problemas fitossanitários buscam a cada cultivo novas áreas para produzir. A semeadura no espaçamento 3,0m x 1,5m, foi feita em novembro, com ressemeadura em dezembro de 2000. As cultivares foram avaliadas quanto à produtividade e ocorrência de doenças. Em termos de produtividade, a cultivar Vista F1, com 10,8 t.ha-1, foi significativamente mais produtiva que a cultivar Vitória F1 (2,6 t.ha-1). Quanto a ocorrência de doenças, a cultivar Athens F1 apresentou o menor número de plantas com sintomas de antracnose (Colletotrichum orbiculare), com 5,4 plantas, diferindo estatisticamente das cultivares Vista F1, Crimson Select, Crimson Magic F1, com 9,2, 8,6, 8,5 plantas, respectivamente, e das cultivares Vitória F1, Arriba F1 e Verona F1, com 8,1 plantas com sintomas. O peso 6,4 Kg por fruto da cultivar Crimson Magic F1 foi significativamente maior que o peso de frutos das cultivares Vitória F1 (4,4 Kg) e Crimson Sweet (4,4 Kg). O peso de melancias das demais cultivares foi intermediário e não diferiu estatisticamente do peso médio da cultivar Crimson Magic F1. Na classificação dos frutos por peso, somente as cultivares Athens F1 e Vista F1 apresentaram frutos com peso acima de 10 Kg, frutos na categoria especial. As cultivares Verona F1, Crimson Magic F1 e Vista F1 apresentaram a melhor performance em relação ao número de frutos na categoria 1, isto é, frutos com peso entre 6 e 10 Kg . As cultivares Vista F1 e Crimson Magic F1 destacaram-se na produtividade e a cultivar Athens F1 destacou-se na resistência a antracnose. Estas cultivares são promissoras, mas são necessários novos ensaios para consolidar estes resultados.

O medo no contexto organizacional

This study looked for identify the causes and the effects of fear in the individuals within the organizational context. The procedure for data collection consisted in a questionnaire divided in two stages, and applied in 76 individuals. The first stage consisted in a words evocation test and the second, as a complementary mode, was composed by four open questions. The theory of social representations and the central nucleus theory were the foundations of the data analysis of the words evocation test. The processing of the open questions was consisted in an interpretative analysis, based in the presented theoretical referencial and supported by the respondents social representation of fear. In the enterprises context, different causes and effects of fear had been found in the inserted individuals. However, in its majority, it was identified that the biggest individuals fears are the unemployment, the threats, punishments, the unstable and unsafe environments of work, the unfair competition, the collusions, sabotages, tricks, the incapacity to do its work¿s tasks and the abusive increase of the work load. On the other hand, about the fear¿s effects, there is a frequent physiological and psychological instability when they had been submitted in high work loads. The fear is an excellent creativity, innovation and aptitude repressor, and it is capable to generate disgusts, frustrations, defensive postures, standstills and to increase the jobs navigability.

Índia e crescimento: modelos tradicionais e impacto da filosofia hindu

A Índia, com sua notável expansão econômica, cultura e filosofia milenares, é o tema desse trabalho, com dois objetivos: exemplificar diversos aspectos teóricos ligados ao crescimento econômico e aprofundar o estudo de um aspecto institucional pouco difundido na literatura, os impactos das filosofias religiosas. A princípio, são analisadas as reformas econômicas realizadas após a crise do balanço de pagamentos ocorrida em 1991. Diversos estudos teóricos são citados ao longo do texto para contextualizar o efeito das reformas no potencial de crescimento. O setor externo é analisado com profundidade, seguido pela desregulamentação no setor privado, principalmente na atividade industrial e no controle de preços. Estes dois setores foram conjuntamente responsáveis pelo grande salto de produtividade na economia (descrito pelos impactos na produtividade total dos fatores). Alguns aspectos de política monetária e fiscal também são analisados, mas com menor ênfase, visto que as reformas e resultados nesses setores são limitados. A seguir, apresenta-se análise sobre a filosofia Hindu, predominante no país. Introduz-se o tema com breve descrição dos aspectos filosóficos, para seguir com avaliação dos impactos econômicos resultantes. Max Weber e Amartya Sen contradizem-se sobre o sinal do impacto: Weber suportando que a magia hindu impediria o racionalismo; Sen argumentando que o próprio hinduísmo tem histórico de racionalismo heterodoxo, de contestação e criação. Para disseminar dúvidas apresenta-se um modelo econométrico, com base em convergência condicional: impactos diretos e indiretos não se mostram significantes. Levanta-se um debate e um alento a alguns países: um histórico institucional bastante desalentador ao desenvolvimento, baseado em uma filosofia religiosa controversa de nuances pós-vida, pode ser superado com algumas corretas reformas na economia.

A magia dos invencíveis

Esta dissertação de mestrado parte da constatação de que o sistema econômico social brasileiro. Apresenta uma anomalia ao propor, em leis e planos de desenvolvimento, a não inclusão do negro; com sua cultura e valores diferenciados, no projeto global de nação. Pretende, a partir daí, refletir sobre alguns pontos da Escola Tia Ciata, uma escola da rede do município do Rio de Janeiro, que objetiva basicamente alfabetizar adolescentes e jovens adultos, entre 12 e 20 anos, rejeitados pela escola regular, dando-lhe condições de se profissionalizar numa sociedade letrada, ao aprender a ler, escrever e contar. Por outro lado, ao discorrer sobre a experiência, tomou vulto uma dimensão inimaginável a priori e que se refere à origem histórica daqueles que são Invencíveis para o sistema escolar instituído e que por isso não conseguem ser “educados" e "civilizados". Procurar entender os Invencíveis, o significado e a magia que a "rua" tem para eles, significa pesquisar as propostas e projetos das classes dirigentes, para essa clientela, visando "ordenar a desordem". Por fim, diante da caracterização possível desses Invencíveis, tomando como base os alunos da Escola Tia Ciata, tenta-se descrever a Escola Imaginária e a que se tornou real, hoje. Quais as suas inovações básicas, sua forma de abordar o aluno que se pretende educar e a possibilidade de intervenção na rede pública escolar, de modo a abrir a perspectiva de transformação do quadro educacional atual.

Escola : da magia da criação : as éticas que sustentam a escola pública

Esta tese procura mostrar como a Escola Pública consegue recriar-se e permanecer apesar dos antagonismos e problemas que a consomem indefinidamente. Ela resulta de um estudo de caso, desenvolvido na Escola Estadual de Ensino Médio Bandeirante de Guaporé, (RS-Brasil), nos anos de 2000 a 2004. A partir de uma perspectiva sócio-antropológica, ancorada em aportes teóricos de Georges Balandier, Edgar Morin, Michel Maffesoli e Humberto Maturana, o pesquisador utilizou-se dos meios e técnicas conferidos pelo método etnográfico de pesquisa para investigar os movimentos de ordem, desordem, organização e mudança na Escola, buscando enfocar os vitalismos que a perpassam e lhe dão jovialidade. Pela observação reflexiva, registrada em diário de campo, procurou perceber nas ações de conduta, comportamentos, posturas e atitudes dos sujeitos o fluir das emoções, geradoras das éticas que perpassam as relações, bem como as ambigüidades de sua manifestação. Por meio de entrevistas, com amostras selecionadas de professores, pais, alunos e funcionários, investigou as razões e motivações de suas presenças na Escola, bem como as qualidades, sabores e dissabores por eles produzidos na convivência. Pôde conferir que, como organismo vivo, a Escola pública se configura em teias de relações onde magia, criação e sentidos encontram espaço de manifestação nos prazeres que a convivência produz.É nesta Estética do Estar-Juntos que o autor percebeu a fonte inesgotável das Éticas que se transfiguram nos encontros, reencontros e relações e que possibilitam a Escola auto-organizar-se e recriar-se constantemente, produzindo os liames de sua e sustentação e permanência, apesar do turbilhão que a consome.

Fragmented messages : a reading of L.P. Hartley's novel The go-between

A intenção deste trabalho é efetuar uma leitura do romance O Mensageiro, do autor inglês L.P. Hartley, na forma de uma jornada ao país estrangeiro do passado do protagonista-narrador. Tal leitura é uma espécie de convite aceito para a viagem, que esteticamente deixa sugestões sob a forma de truques, fragmentos de mensagens veladas, expressões ambíguas, sombras, vazios no caminho. Todavia, Mercúrio, o mensageiro dos antigos deuses, o protetor dos viajantes, o trapaceiro, é agora um ser indistinto, cuja imagem e função passou por grandes transformações ao longo da viagem até a modernidade. Guerras, restos de experiências traumáticas coletivas e pessoais são recuperadas na rota movediça do narrador melancólico, sob a forma de substância própria para a narração. Nietzsche e Walter Benjamin são companheiros na trajetória, provendo o suporte teórico básico para a viagem.

Espirito de catimbo: a moral magico-religiosa da jurema

This participative research interested in the social praxis attempts to understand the moral principles that set the magic rituals and the places of worship of three jurema centers of the potiguar region of Canguaretama. Among other inner particularly aspects of each focused catimbó-jurema center, it is being discussed the collective standards involved in the reliance and fellowship values assumed in the private magical gatherings by the juremeiras leaders and their partners, in contrast to the prestige seeking and the individualism that influence both the symbolic competitions and the witchcraft works that link these agents to the broader catimbozeiro universe of this region. Finally, the moral practices which make part of the juremeiro left-right dualism are investigated based on the understanding that the referred native pantheonic-ritual dichotomy does not necessarily express two moralities substantially adversed in terms of benefits or harms, but a series of moral actions subject to the specular logic of the tit-for tat. Thus, this research seeks to prove that this moral structure of symbolic reciprocity, as well as the witchcraft centrality in the catimbozeiro world, finds a certain causal link in a world view which guiding principle is the ontological evil of the catholic cosmology

Os trabalhos de amor e outras mandingas: A experiência mágico-religiosa em terreiros de umbanda

The following text addresses the magical-religious experience carried on by many individuals when they seek to solve their love, financial and health problems by means of white magic spells done by pais-de-santo e mães-de-santo (saint s father and saint s mother) from umbanda. The rites through which this seek can be detected are free love spells, troublesolving spells, and healing spell. The concept of experience, here understood as the thing which gives sense to the sense, has been the main guiding idea of the reflections here enclosed. People who seek the umbandista spells as a way of solving their daily afflictions have the opportunity of living a rich magical-religious experience in which several dimensions intersect. Among these dimensions I decided to study the performance, the knowhow and the subjetivity. Each one gave rise to the opportunity of studying a range of other themes, such as the corporeity, the gestuality, vocality, the world knowledge, the science, the secret, the emotions and the moral. The ethnographic research was carried on in the yards which are named after Dona Luiza, Pai Gledson, Pai Salviano and Dona Terezinha umbanda, all of them situated in the town of Limoeiro do Norte, Ceará

O tempo das brincadeiras : memória, turismo e tradição em Barra do Camaratuba PB

Barra do Camaratuba belongs to Mataraca city, nearby the boarder between Paraíba and Rio Grande do Norte states. It was the chosen community to develop this research, objectifying to study the set of practical of the cultural manifestations and the implications of the local tourist activity, considering the cultural dynamics. We tried to reconstruct stories from the narratives of the oldest inhabitants, natives, among others that they had lived, some how, individual and collective experiences related to the popular tricks and the traditional parties, considering what they speak and imagine about their experiences and its culture. The Lapinha, the Pastoril, the viola s songs, the Balls of Concertina, the João Redondo, the Ox of Kings, the wheel of Coconut were common practical perceivable through the communitarian bonds. Among these manifestations, the only one that resisted for a longer time was the wheel coconut. The São Pedro s fest is another popular manifestation that appears on the current scene like the padroeiro party, while others cultural practical compose the spectacle s scenery. These questions cover many of the narratives of the interviewed ones in the interlaced thing between memory, tourism and tradition. Therefore, we tried to build our research from the memory, participant observation, orality, techniques of the life history, personal depositions, among others basic methods for the reconstruction of a collective memory . Speaking about the past of Barra do Camaratuba is to live again the parties, the blood relations, the terço , the work in the roçados , in the flour house, the fishing, the leisure and the habits of the daily life. In this community, there is the presence of conflicts of social and cultural order, caused for the hegemonic classes that sponsor the parties. In the padroeiro party we perceive that the mercantile logic has started, very recently, to transform the religious factor into an excuse to put into motion the local economy. This way, a community originated from artisan fishers and agriculturists, having the fishing practical as a way of subsistence and the tricks as a reference, they had started to compose a new social picture with the arrival of the others and with the presumption and recent tourist development. We perceive social, environmental and cultural impact transformations, exemplified by a non planned activity or a predatory tourism. The changes will always be pointed and compared with other passing in a sphere of relations lived by the natives, local players and fishers

Teodora e Porcina: faces simbólicas da natureza em narrativas de mulheres sábias

This research looks at the collective imagination in which it keeps alive the issue of heroin wise. Two wise women appear in the narratives of popular history and the History of Donzela Theodora and History Imperatriz Porcina, collated by Luís da Câmara Cascudo in his Five Books of the People. The universality, mobility and circularity of these narratives are discussed by authors such as Bakhtin and Guinzburg. The research is developed from three key categories: Knowledge Magic as the knowledge of tradition (Almeida), sensitive knowledge (Levi-Strauss), thought mythical / magical / symbolic (Morin); Wise Women as carriers of this knowledge, which merge and overlap with the imagery of witches and healers; and Mythical Elements which corresponds to the archetypal images (Jung and Silveira), symbols and other images that relate to the magic universe, the magical beliefs and practices considered, ie belonging to the imaginary magic (Bethencourt). Porcina and Theodora are understood as bearers of knowledge of Métis (Detienne and Vernant), or the cunning intelligence, the manipulation of phármakon (Derrida), the healing potion, which may be the word or ointment of the herb. The route takes us to meet the great archetype of the Wise Woman as psychic power of the feminine, the anima. Narratives are medicinal balms (Estes) and is the clash between the anima and its embodiments by wise women, and animus, his opponents, which gives the transmutation of the psyche, a work comparable to that of alchemyThe Knowledge Magic, operating through the female, myth and nature can recover from its essential value to the emerging paradigm that suggests a more complete human science and a more plural

A arte rupestre como expressão comunicativa da cultura

Along their existence, through of the millenniuns, the Man registers, one way or another, their saga. One in those registration ways is the rupestrian art. Through the rupestrian art the Prehistory is brought even us, portraying in images the daily ritualist and magic of the Man, in scenes that show, among other, their cults and also their daily hard work. The Man is imposed, while registering of their existence, starting from the moment in that he is capable to leave their marks through the transformation that attributes to the Nature; also for the produced interferences and for the cultural singularities that themselves were constituted before the period of the alphabetical writing. In an artifice of duplicating utensils and in the sense of representing animals and to himself own, he delegated us a communicative system whose contexts and details were - and it continue being - an enigma to be deciphered. Starting from this argument, the research has for objective to understand the daily and the history of cultural groups that they preceded us, taking as base the reading of the rupestrian paintings found at the located archeological ranches in the Area of Seridó, more specifically in the Complexo Xique-xique, close to the Municipal district of Carnaúba dos Dantas, distant 220 kilometers of Natal, the capital of Rio Grande do Norte State

Educação - Corporeidade - Lazer: saber da experiência cultural em prelúdio

In the passage of life, the labyrinth of songs and corners are propitious ways for a better comprehension, perception and incorporation of learnings that emerge from our subjectiveness in a magic caught by senses. Eyesight, taste, hearing, touch and smell in communication with the world, put us in front of cultural diversities. The ludicity accumulated by experiences promote the flow of hilarious and concrete discoveries that express themselves in work and leisure demonstrations. Such reflections emerge indicators to the problematic construction centralized in the incorporation of cultural experience knowledge to the formation process and professional interventions in this rule and area. From this significant problematic, aiming to deepen studies, we favored leisure as field of investigative production in full expansion. This, for sure, was an exercise of qualification that guided us through meander of education and made us dip into studies about the corporeity. A research in which the scenery was painted and constructed with the complicity of the culture lived with shine, colors, rhythm and drummings of one of the most present cultural cycles: carnival. Recognized as a stimulant for beauty, participation, socialization, and helped us to enter in the essence of gestures and expressions of corporeity, to think, elaborate and socialize a critic-scientific knowledge which, appropriating from the rhythm of colors, of sounds, of tonalities, of senses and of meanings impregnated in the web of life. All these things seduced the researcher, making imagination flow amid ludic-creative dialogues with the imaginary of researchers creation and production in the rule and area of leisure, education and corporeity. Option that made us outline as objective to investigate and interpret how leisure teachers-researchers, from their studies, researches and interventions, locate and incorporate the knowledge from cultural experience to the formation process and intervention of professionals in this rule and in this area, emphasizing the contributions from this knowledge to fence and qualify this praxis. So, as living each cultural scenery, each epistemological contribution was feeding the production with images of the different versions of the Brazilian breedings, creating and raising expectations and new discoveries and newcomers. With the seriousness of a scientific study, we lived an xxiii academic experience with complex intensity, rigor and coherence, eliminating, step by step, the risks and limitations always present in a work of this magnitude. However, we weren t, even for one moment, alone. Our epistemic regard always maintained mediated by the principles of a methodological approach - the Etnomethodology, that while central guide provided us clues to unveil the lived world by our people-playful , in a universe of 15 members, that allowed themselves to comprehend, comment, analyze. This way, grasping the object in interactions arised and provoked by narrative interview, it was systematically dialected by (re) interpretation of images and formulations of people-playful, enriched by their beliefs, myths, conceptions and rituals inherent to knowledge from cultural experience, which each one attuned with Brazilian and international history, in a mixture of senses echoed from songs and tales. Inspired in drummings and percussions, clothing and choreographies of gestures and expressions, in mixtures produced in unit interactions in the multiplicity shown as necessary requests to the totality of life, with ludicity the rescue of the past, the conquest of present and the construction of future was the axle guide. This rich process of scientific creation made us realize that is possible qualify and empower the praxis in the rule and area of leisure incorporating the knowledge from cultural experience. What also becomes possible is the recuperation of objective revolutionaries and changing conditions of praxis itself with the view of strengthening and triggerment of vital elements in the rule and area of leisure. We also reaffirm that from this praxis emerge elements necessary to human formation in plenitude, by the appropriation of knowledge that guide the facing of challenges of a complex and plural world that valorize education, corporeity and leisure
