La séparation entre les deux cultures (Snow, 1995) a battu la compréhension du monde, a influencé l'éducation à tous les niveaux et a fragmenté les êtres humains dans leur façon de penser et de produire des connaissances. L'accumulation des connaissances héritées dès la naissance de la science moderne au XVIIe siècle, n'a pas été suffisantes pour relever les nouveaux défis du monde contemporain (Morin, 2000, 2001, 2002a). Maintenant c est le temps de chercher une nouvelle compréhension du monde et des nouveaux façon de comprendre et résoudre les événements et problèmes de l'âge moderne. La Pédagogie de la fraternité écologique "est défendue et construite à partir d'un point de référence cosmologique nouvelle, basée sur le grand récit de l'univers, et inspirés par la vie fraternelle, l'amour, la poésie et la sagesse de saint François d'Assise (Italie , sec. XII-XIII) et l'expérience des connaissances traditionnelles et la «logique du sensible» (Lévi-Strauss) de Francisco da Silva Lucas, un résident de la communauté de Areia Branca, sur les rives du lac Piató dans la ville de Assu, Rio Grande do Norte. Une épistémologie fondée sur le grand récit de l'Univers rachetera des relations fraternelles entre l'homme et la nature. À partir de ces références j ai elaboré une nouvelle formation pour les éducateurs, «formation interdisciplinaire pour enseigner de l'éducation», dans lequel je développe ce que j'appelle «Architecture transdisciplinaire de savoir pour la formation des enseignants, fondé sur les principes de la complexité et de la transdisciplinarité. Nous comprenons que notre rôle est plus large intégrant l'homme dans l'histoire de l'univers, car le bien de la terre et le bienêtre de la communauté humaine sur terre peut être le point que rejoindra l'enseignement de l'avenir

A detecção, a transmissão e o efeito de Xanthomonas campestris pv. campestris (Xcc) na qualidade fisiológica de sementes de brócolis (Brassica oleracea var. italica) foram avaliados, a partir de sementes obtidas de plantas (Baron, Flórida, Hana Midori Sakata, Precoce Piracicaba de Verão, Ramoso Santana e Sabre) inoculadas com a bactéria, em condições de campo. Para a detecção do patógeno nas sementes foram utilizados os meios de cultura semi-seletivos: SX ágar, NSCAA e BSCAA; a taxa de transmissão da bactéria pelas sementes às plântulas foi avaliada usando semeadura em areia e meio de cultura contido em tubo de ensaio. Para a avaliação da qualidade fisiológica de sementes foram realizados o teste padrão de germinação e os testes de vigor: envelhecimento acelerado, índice de velocidade de emergência, crescimento de plântulas e massa seca. de acordo com os resultados, o meio de cultura semi-seletivo NSCAA foi mais eficaz para detectar Xcc em sementes de brócolis; não houve diferença significativa entre os genótipos na taxa de transmissão da bactéria pelas sementes e Xcc não afetou a germinação e o vigor das sementes.

Um amplo projeto de estudos sobre a utilização do umezeiro como porta-enxerto para pessegueiro está sendo desenvolvido na FCAV/UNESP, Câmpus de Jaboticabal-SP, devido, especialmente, às promissoras características para uso como redutor de vigor da copa e sua boa qualidade de frutos. Alguns trabalhos na literatura citam o umezeiro como resistente ao nematóide das galhas, entretanto dispõe-se de poucas informações. Neste trabalho, teve-se por objetivo estudar a reação de clones de umezeiro e cultivares de pessegueiro a Meloidogyne javanica. O experimento foi conduzido em casa de vegetação, com 6 tratamentos (Clones 05; 10 e 15 de umezeiro e as cultivares Okinawa, Aurora-1 e Dourado-1 de pessegueiro) e 9 repetições. As plantas foram mantidas em vasos de cerâmica contendo uma mistura de solo e areia (1:1, v/v), previamente autoclavada a 121ºC e 1kgf.cm-2 por 2 horas. Aos sessenta dias após o plantio, cada planta foi inoculada com 3.000 ovos e juvenis de segundo estádio de Meloidogyne javanica. Aos 100 dias após a inoculação, as plantas foram colhidas para avaliação da massa de matéria fresca do sistema radicular, número de galhas por sistema radicular, número de ovos e juvenis por 10 g de raízes, número de ovos e juvenis por sistema radicular e fator de reprodução. Verificou-se que todos os clones e cultivares de umezeiro e pessegueiro, respectivamente, mostraram-se resistentes a Meloidogyne javanica.

O presente estudo teve por objetivo avaliar a reação dos Clones 05; 10 e 15 de umezeiro (Prunus mume Sieb. et Zucc.) e das cultivares Okinawa, Aurora-1 e Dourado-1 de pessegueiro [Prunus persica (L.) Batsch] a Meloidogyne incognita (Kofoid and White) Chitwood, em condições de casa de vegetação. As plantas foram mantidas em vasos de cerâmica contendo uma mistura de solo e areia (1:1, v/v), previamente autoclavada a 121ºC e 1kgf.cm-2 por 2 horas. Aos 60 dias após o plantio, cada planta foi inoculada com 2.000 ovos e juvenis de segundo estádio de Meloidogyne incognita. O experimento foi conduzido em delineamento inteiramente casualizado, com 6 tratamentos (genótipos) e 9 repetições. Transcorridos 116 dias após a inoculação, as plantas foram colhidas para avaliação do sistema radicular. Foi possível verificar que o número de galhas por sistema radicular, o número de ovos e juvenis por 10g de raízes e por sistema radicular foi nulo ou praticamente nulo em todos os clones e nas cultivares estudadas, de forma que os respectivos fatores de reprodução foram todos inferiores a 1. Conclui-se que os Clones 05; 10 e 15 de umezeiro, assim como as cultivares Okinawa, Aurora-1 e Dourado-1 de pessegueiro são resistentes a Meloidogyne incognita.

Tem sido atribuído a vários patógenos reduções na qualidade de sementes de soja. Com o objetivo de avaliar o transporte dos fungos pelas sementes provenientes de plantas de soja, artificialmente inoculadas em condições de campo com dois isolados de Colletotrichum dematium var. truncata e um isolado de Phomopsis sojae, e seu efeito sobre a qualidade sanitária e fisiológica das mesmas, quatro variedades de soja (BRS 133, MSoy 6101, Conquista e Liderança) foram manualmente semeadas no campo, e as plantas obtidas foram inoculadas com C. dematium var. truncata isolado 1 e isolado 2, e P. sojae. A testemunha permaneceu sem inoculação. As sementes foram colhidas manualmente e submetidas a testes para avaliação da sanidade, teor de água, peso de 100 sementes, germinação em papel e emergência em areia. A desinfestação das sementes com hipoclorito de sódio a 1% por 3 minutos diminuiu a incidência dos patógenos nas mesmas. As sementes apresentaram uma alta infecção por Fusarium spp.. Phomopsis sojae foi encontrada em todos os tratamentos, e sua incidência nas sementes esteve relacionada com a incidência de Fusarium sp.. Há diferença na patogenicidade entre isolados de C. dematium var. truncata, sendo o isolado 1 o mais patogênico, com destaque para a variedade Liderança (25% de infecção por C. dematium var. truncata). Fusarium sp. influenciou negativamente a germinação de sementes da variedade MSoy 6101, independente do tratamento, e C. dematium var. truncata afetou negativamente a germinação das sementes das variedades Conquista e Liderança. Os valores de emergência em areia apresentaram-se significativamente superiores à germinação em papel, para as variedades MSoy 6101, Conquista e Liderança.

The issue of multi-classes in schools from the field and methodology for these classes is controversial and contentious, both in terms of teaching, monitoring and organizational, is the perspective of values, training and systematization of public policy. Why the strategy Methodological Active School facing those classes appeared as a significant and exciting topic of research. Thus, it was aimed to apprehend the social representations of active school by teachers (s) to understand the extent to which these representations influence the acceptance and use of the program strategies. Perceiving and analyzing also the various factors related to the management, monitoring and training needs of (the) teachers as alternatives to make this meaningful action. The study focused 112 teachers (s), which for over a year, worked in the program in six municipalities in the micro-region of Rio Grande do Norte / RN - Areia Branca, Baraúna, Grossos, Mossoró, Serra do Mel and Tibau. From this perspective relied on Social Representation Theory and the Theory of the Central Core, attending to the subjectivity of the object searched, inserted in the psychosocial field of knowledge, we opted for multi-methodological approach, using quantitative and qualitative techniques. However, the highlight was a projective technique Free Association of Words from the term Active School is .... The words were systematized by EVOC program, and also applied semi-structured interviews, focusing specific issues that led to trace the socio-demographic profile of (the) participants and wider issues about the object of study. The evocations, justifications and interviews provided the basis for the analysis of the content that followed the steps: formation of the corpus, the composition of the analysis and categorization. The results show the representations an attitude of acceptance and positive appraisal of the participants to the Active School Program. At the core, these representations are objectified around the words "action", "learning", "autonomy" and "interaction". Based on the premise that the representations have a duty to guide the practices and behavior, one can see that the positive attitude of the group favors a systematic methodology and acceptance of the program, but we must look at the changes in management, training, monitoring of (the) teachers (s) and support to schools.

The present work concerns an auto-ethnographic study based on life experiences and reflections of an educator at Escola Viva Preschool and Elementary-Middle School, located in the city center of Natal, Rio Grande do Norte. As a cognitive model of operation, we use the metaphor of the Circle Dance. The objective of this study is to identify, interpret and describe the ludopoetics that are achieved through a Musical Education program, which we denominate, Humanescent. The data of this investigation was derived from the music making by Preschool and Elementary-Middle School students at Escola Viva during 2007, 2008 and 2009, from which 20 learners were selected to form the corpus, along with the description and interpretation of photos of their experiences and sand tray scenes. We justify the methodological systemization of the research based on our own pedagogical practice, which supports Musical Education in the schools based on the principals of Embodiment, Autopoesis and Flow. The methodological systemization was developed through an Action Research model and on the concepts of Systemic Development, with the goal of re-reading the context investigated through the structuring of categories of Ludopoesis: Self-esteem, Self-territory, Self-connectivity, Self-realization and Selfworth. We used an observant-participant research approach with regard to the perception of emergent knowledge, the surroundings, the experience lived and the contextual and vibration of the circumstances. Besides this, we used projection to interpret the experiences lived, in the form of drawings, short poems, letters or sand tray scenes as symbolic interpretations of experience. In the unfolding of the Ludopoetic Process (Selfesteem, Self-territory, Self-connectivity, Self-realization and Selfworth) we draw conclusions about the relevance of the ludic musical experience, which foments the formation of the self based on music learning, and which is demonstrated in the Embodiment of the learners. In the auto-formative process (of learners and educators) we observe the importance of pedagogical work based on Musical Humanescent Education that gives value to the music making path to the construction of music and performance in play, creativity, and sensibility. The experience of making music in a playful way allows for organization of the self and its autonomous production in the joy of living within a ludopoetic process. These findings highlight the educator as in a permanent state of selfformation, which generates moments of flow. However, in Musical Humanescent Education, music is learned collectively, doing a circle dance, experiencing love, fostering an expansion of the creative spirit, and giving recognition to playfulness as a necessary condition for education and to the value of music made with the true nature and sensibilities of the educators

This study shows the movement of educators ludopoiese ecosystem of the Center for Early Childhood Education Marise Paiva-CEIMAP. We used the metaphorof dance as an opportunity to stimulate scientific creativity. Ecosystem Thought, complex thinking, the theory of autopoiesis and Flow Theory, constituted the main theoretical steps to understand the phenomenon of ludopoiese, from the look of your totalidadem with the following objectives: 1 - Identify and interpret the process of self ludopoiética CEIMAP of Early Childhood Educators in the actions of the play, care for and educate in school life; 2 - Analyze Ecosystem Thought from ludopoiéticos how these processes affect and / or possible changes and transformations in practice humanescenteseducational CEIMAP. The theoretical metodógicos steps to address the proposed objectives are grounded in existential action research part of the appreciation of the complexity of the real, considering the human being a whole dynamic. In this sense the game of sand, recreational experiences, the systematic studies and video training were explored with a view to the transdisciplinary relevance of everyday phenomena. New knowledge acquired in accordance with the directions given indicating the movement of the ecosystem studied ludopoiese educators, involved in four main streams: love, play, care for and raise it from love streamline interdependently. The ludopoiese eachteacher would then be fed by this web generated by love that permeates all other educational activities, nurturing and maintaining a constant creative self-organization of knowledge and know-how to be teachers. Thus, every network that generates andstream lines the system emerges ludopoiético biology of love, the open dialogue and playing in the wishing well to the student, the aesthetic beauty of caring and educating, as a human conditionand relevant as possible to live / live not only in teaching children, but in other educational contexts of teaching and teacher education

L étude vient de présenter la recherche qui a eu lieu pendent la formation des professeurs d l'Institut d'Enseignement Supérieur Président Kennedy à Natal-RN, dont les sujets son les professeurs de la septième période du Cours Normal Supérieur. L objet d´étude sont les pratiques formatives de ces professeurs en formation par des difficultés qui ils présentaient pour comprendre les relations entre les domaines de connaissance le l interface avec les expériences, et le processus de formation. L objectif a éte identifier dans l expériences ludopoèthiques, les lieus de construction de l autoterritorialité des professeus en tant qu en formation. Parmi les pressuposés théoriques qui ont soutenu le développement de la recherche comprennent: Enseignement Humain ; Corps-espace; Corporéité; Auto-formation et Transdisciplinarité. L'approche de la recherche qualitative adopte les principes de la rechercheaction- formation, dans une perspective etnophenomenologique. La discipline Memorial de Formação avec l'utilisation de jeu de sable,a été le laboratoire des expériences, l outil de la recherche qui a subventionné la construction des narratives autobiographiques. La perspective transdisciplinaire sur l'étude a rassemblé dans la dimension épistémologique les références théoriques de la Géographie, de la corporéité. et des histoires de vie dans la formation. L'Atelier Corps (Bio) Géographique a été développé par cinq rencontres: Paysage du Sensible, Lieu de Sentipensar, Territoires des Découvertes, Région des Savoirs et de l'Espace Géographique de la Ecoformação. Les expériences vécues dans l'Atelier par les participants de la recherche ont permis une sensible et attentive écoute sur leur propre histoire, en donnant la possibilité de la reconstruction de la mémoire, et en faisant réfléchir sur son l'auto-formation. La découverte des cartes et la construction d un nouveau paysage autoformatif par les memoires ludiques des différentes phases de la vie, a fait apparaître la propriété ludopoètique de l autoterriotalité, au même temps qui a enrégistré la construction ontologique dans sa corporéité

A partir de una concepción de la educación como una obra de arte, la disertación revela los estudios realizados en una escuela de la comunidad de Areia Branca Piató, en la Laguna de Piató en Assú, Estado de Rio Grande do Norte. Como una forma de hacer dialogar conocimientos científicos y saberes tradicionales, la investigación establece el intercambio de saberes y afectos sobre todo por intermedio del intelectual de la tradición Francisco Lucas da Silva. Para construir un conocimiento pertinente (Edgar Morin), el que forma parte de un contexto, buscamos aquí la comprensión de una pedagogía viva e imaginativa. La disertación encontró en la Laguna un laboratorio vivo para pensar en una enseñanza educativa y para ejercer el pensamiento complejo. A partir de estudios e investigaciones anteriores, pude organizar lo que considero que se constituye como constelaciones de saberes que permiten dar continuidad a ese eje de investigación que empezó desde 1986 en el Grupo de Estudios de la Complejidad GRECOM. En la construcción de este trabajo, pude aprender valores que creo que son importantes para una educación compleja: la humildad delante de la vida; la abertura para diferentes lenguajes del mundo; el diálogo con la naturaleza; la apuesta en nuestras creencias; el sueño de resignificar a la realidad a partir del lazo entre la profundidad de nuestro ser y el mundo; el uso pleno de nuestras potencialidades imaginativas y creativas; y, finalmente, la vivencia intensa de los sentidos. Partiendo de ese aprendizaje, la investigación teórico‐práctica tuvo como elemento central el desarrollo de talleres sobre el tema del agua con alumnos de la enseñanza básicas de diversas series, y con la participación activa de dos profesoras de la comunidad de Areia Branca Piató. Fueron llevadas adelante experiencias que contemplaron una visión sistémica de la naturaleza, las fotografías, los atelieres, las clases de campo, el arte de educar, la narración de historias y sobre todo las enseñanzas del intelectual de la tradición Francisco Lucas da Silva

This research has as study objective the development of humanescent experience in the process of self-formation of the teachers of the Infantile Educational Unit of the Education Center of the Federal University of Rio Grande do Norte. It has as general objective the description and analysis of how the humanscent experience of life contributes and is manifested in the children educator in his way of being, living and in his pedagogical practice. As specific objectives, the identification of the contributions of the humanescent experiences in the children educator in his way of being, living and in his pedagogical practice; the analysis of the contributions of the humanescent experiences to the children educator from the ludopoetic categories self-esteem, selfworth, self-realization, self-territory and self-connectivity. It is a descriptive study of qualitative nature understood as an existential action research that uses the principles and fundamentals of the etnomethodology and phenomenology. Sixteen teachers six that are effective teachers, six substitute teachers and 4 interns - took part in this investigation. Six humanescent experiences were carried out with them. As main tools we point out: the participative observation, the sand game, the photographic register and the semi-structured interview. The analyses were centered in the categories of the ludopoetic system, described above and referred to in the theoretical fundamentals selected for the study. From the analyses and to the answers to the objectives of the study, we make clear the following considerations: the reports of the teachers reveal that the humanescent experiences have contributed to make them more ludic, sensitive, emotional and lovely people, and this has reflected in their educational practice and has been making sense in their and their students lives. In this way, we make evident that the humanescent experiences have contributed to improve the ludopoesis of the teachers, revealing in the embodiment changes in their way of being, of living together and in their educational practice. In relation to the contributions of the humanescent experiences to the children educator from the ludopoetic categories self-esteem, selfworth, self-realization, self-territory and self-connectivity, we emphasize the following aspects: with the self-esteem, teachers have become more creative, rebuilding their possibilities of intensely experiencing the pleasure of living; in the context of selfterritory, the teachers have provided the realization of the wishes and expresson of oneself while lively interacting with the environment and with the other different territories of the educational process, in a continuous process of demarcation. Concerning the self-connectivity category, we emphasize that the teachers started to become more tuned with themselves, with the environment and with the other teachers because of the general well-being to the success of personal, pedagogical and institutional objectives, promoting a harmonic, lovely and ludic environment. Concerning the self-worth category, the teachers have valued the struggle for a school that is more committed with the search for happiness. From the self-realization, the teachers have shown self-recognition while ludic beings, playing with the beauty in their lives, allowing the flowing in its completeness, the other possibilities of analysis, the educational formation and development. We would like to emphasize that the considerations above are not over after what has been presented because of the richness of experiences revealed in the research

This thesis objective systemize and discuss the ecological knowledge constructed by means of tradition knowledge with basis in a complex ecology (MORIN, 2002b). The conception of tradition knowledge (ALMEIDA, 2001c) corresponds to a diversity of knowledgement, of men and women, constructed from heteroclite elements of the geographic way, making use of analogies and homologies which serves as the base for this scientific inquiry. These knowledge are extremely related the context where these people are inserted. To construct an ecology of complex base is to understand that the reality is not given previously, and that its construction assumes indissociability among the elements that composes it, that is, between nature and society, material and immaterial elements. To incorporate the disorder, the uncertainty, the unpredictable and the auto-echo-organization as guide principles of a new ecology, constitutes in a new vision of the biological science and the scientific ecology in direction to a science of complexity. The work focuses the ecological knowledge of the Piató lagoon, municipality of Açu, in the State of Rio Grande do Norte, having as interlocutor of this boarding Mr. Francisco Lucas da Silva (known in the local as Chico Lucas), fisherman and agriculturist, who was born, and lives until today, in the community of Areia Branca, around the lagoon. Having for base the method as strategy (MORIN, 2001a), the research construction was performed through the realization of more than 10 trips carried out between the years of 2005 and 2007. In these trips the ecological aspects of the environments such as, the flora and the fauna, as well as the environmental impacts on the lagoon, were obtained in recorded dialogues and interviews with Chico Lucas, which were later transcripts. The information from there showed a natural and social complex reality, little known by Cartesian science, since it brings a wealth of details of daily life full, over all, for tradition knowing of the people that had lived there and the ones who remain living there. The thesis looks to understand the strategies of thought and the knowledge production referring to traditional knowing and its ability of interchange between different cognitive operators. The ecological knowledge that emerges of these knows reveals a systemic perception of the environment, presenting the beings and phenomena in its peculiarities and its degrees of complexity, but immutable in its indissociability

Um experimento em casa de vegetação foi conduzido entre novembro de 2006 e abril de 2007, na FCAV/UNESP, Brasil, objetivando estudar a produção de massa seca, a distribuição e o acúmulo de macronutrientes por Ipomoea quamoclit, uma importante planta infestante de culturas anuais e perenes no Brasil. As plantas foram cultivadas em vasos de 7 L com substrato de areia, que foram irrigados diariamente com solução nutritiva de Hoagland & Arnon. O delineamento experimental foi inteiramente casualizado, com quatro repetições. Os tratamentos corresponderam às épocas de avaliação, em intervalos de 14 dias, iniciando-se 21 dias após a emergência (DAE). em cada avaliação, as plantas de quatro vasos foram analisadas quanto à produção de massa seca e ao conteúdo de macronutrientes. I. quamoclit apresentou pequeno acúmulo de massa seca e de macronutrientes no início da fase experimental. Esses acúmulos intensificaram-se após 77 DAE, atingindo o máximo valor teórico aos 146, 143, 140, 149, 142, 153 e 124 DAE, para massa seca, N, P, K, Ca, Mg e S, respectivamente. K e N foram os macronutrientes acumulados em maior quantidade por plantas de I. quamoclit.

Os objetivos deste trabalho foram avaliar o desempenho germinativo de sementes de palmeira-australiana em diferentes substratos e estabelecer a granulometria e intensidade de umedecimento adequado. A semeadura foi realizada com quatro repetições de 25 sementes em solo, areia, rolo de papel e em vermiculita de diferentes granulometrias: mícron (0,15-0,20 mm), superfina (0,21-0,30 mm), fina (0,30-0,50 mm) e média (1,19-0,50 mm), umedecidas com 0,5; 1,0; 1,5; e 2,0 vezes o seu peso em água. O teste de germinação foi conduzido a 20-30 °C, avaliando-se a primeira contagem do teste aos sete dias após a semeadura e, semanalmente, a germinação (plântulas normais) até os 35 dias, quando foram contabilizadas, também, as plântulas anormais e as sementes mortas. Calcularam-se o tempo médio e frequência relativa de germinação. A vermiculita mícron umedecida com uma vez o seu peso em água apresentou o melhor desempenho como substrato para o teste de germinação de sementes de palmeira-real-australiana, por possibilitar a máxima germinação das sementes (90%) e velocidade de germinação, demandando tempo médio de 15,3 dias nesse processo.
