The study was conducted in academic year 2010 in a municipal school in Natal-RN, aimed at investigating the pedagogical practices developed by the participating teachers as well as its view of the front of Intellectual Disabilities students who are inserted in the initial years of Elementary School. In methodological choice, considering the nature of the phenomenon, we chose the qualitative approach and the case study method. The observation and semi-structured interview were used as procedures, which contributed to a significant collection of data in an attempt to answer the objectives. The study subjects were selected by convenience and were formed into two teachers from Elementary School I, linked to the public educational system, which volunteered to collaborate in this research. The analysis of the observations and of the speeches made possible build pedagogical considerations on the action with students with Intellectual Disabilities in a regular school. The results point to a practice covered with a traditional pedagogy, with a few adjustments, although there is an initial process of change, what we observe in the classroom and captured in the words, because, at various times, we saw an interest in developing a pedagogy of Freire. One aspect that caught our attention refers to the formative action at school for these teachers. We found its incipiency, because this does not happen in a systematic way at school. Throughout the years investigated, the teachers had no access to any form of training neither to any form of specialized monitoring. We realize that there is still a concept of Intellectual Disability that makes difficult to "see" this student as a human being having learning opportunities. The aspects that interfere in the formation hinder the development of a pedagogical practice that meets the uniqueness of its customers and promotes a truly effective school inclusion, consistent with social rights proclaimed in this century. We believe in the irreversibility of the inclusive process initiated a few decades ago and that obstacles to the practice of teaching students with ID are visible and possible to overcome if they are turned into challenges for all those who compose the school, the municipal education system and those who build public policies for inclusive education / O presente trabalho se constitui numa pesquisa sobre pr?ticas pedag?gicas de professores que vivenciam o cotidiano escolar com alunos com Defici?ncia Intelectual (DI) nas suas turmas, consideradas inclusivas. A investiga??o foi realizada no ano letivo de 2010 em uma escola municipal de Natal-RN, tendo como objetivo geral investigar as pr?ticas pedag?gicas desenvolvidas pelos professores participantes, bem como sua vis?o acerca da Defici?ncia Intelectual frente a alunos que a apresentam, inseridos em anos iniciais do Ensino Fundamental. Na escolha metodol?gica, considerando a natureza do fen?meno estudado, optamos pela abordagem qualitativa e pelo m?todo estudo de caso. Foram utilizados, como procedimentos, a observa??o e a entrevista semiestruturada, que contribu?ram para uma coleta de dados significativos, numa tentativa de dar respostas aos objetivos propostos. Os sujeitos da pesquisa foram selecionados por conveni?ncia e se constitu?ram em duas professoras do Ensino Fundamental I, vinculados ? rede p?blica, as quais se dispuseram voluntariamente a colaborar nessa investiga??o. A an?lise das observa??es e dos discursos dos sujeitos possibilitou construirmos considera??es sobre a a??o pedag?gica com educandos com Defici?ncia Intelectual, em uma escola regular. Os resultados obtidos apontam para uma pr?tica revestida de uma pedagogia tradicional, com poucas adequa??es, embora haja um processo inicial de mudan?a, o que observamos nas aulas e captamos nas falas, visto que, em v?rios momentos, percebemos um interesse por desenvolver uma pedagogia freireana. Um aspecto que chamou nossa aten??o se refere ? a??o formativa efetivada na escola para esses professores. Constatamos sua incipi?ncia, pois essa n?o acontece de forma sistematizada na escola. Durante todo o ano investigado, os professores n?o tiveram acesso a nenhuma modalidade de forma??o e a pouco acompanhamento especializado. Percebemos que h?, ainda, uma concep??o de Defici?ncia Intelectual que dificulta enxergar esse aluno como um ser com possibilidades de aprendizagem. Os aspectos que interferiram na forma??o prejudicam o desenvolvimento de uma pr?tica pedag?gica que atenda a singularidade da clientela e que promova uma inclus?o escolar verdadeiramente efetiva, coerente com os direitos sociais proclamados neste s?culo. Acreditamos na irreversibilidade do processo inclusivo desencadeado h? algumas d?cadas e que os obst?culos para a pr?tica pedag?gica de alunos com DI est?o vis?veis e poss?veis de serem superados, desde que sejam transformados em desafios para todos os que comp?em a escola, o sistema municipal de educa??o e os que constroem as pol?ticas p?blicas para a educa??o inclusiva

A heterogeneidade de habitat e o clima estacional tendem a causar padr?es de atividade dos organismos e de diversidade de esp?cies. Por?m, esses padr?es sazonais e espaciais em comunidades de borboletas em ambientes secos ainda n?o s?o claros. Estudamos uma comunidade de borboletas frug?voras na ESEC Serid?, no nordeste do Brasil, com o intuito de caracterizar a guilda no semi?rido e verificar a contribui??o relativa de vari?veis clim?ticas e vegetacionais sobre a sua composi??o, diversidade e fenofaun?stica. As borboletas foram amostradas mensalmente, durante um ano, e a distribui??o das esp?cies foi associada ?s caracter?sticas estruturais de tr?s fitofisionomias (ex. riqueza e abund?ncia de esp?cies arb?reo-arbustivas, cobertura de dossel, cobertura de herb?ceas, serapilheira) e a dados climatol?gicos (temperatura, pluviosidade e umidade). Foram capturados 9580 indiv?duos de 16 esp?cies de borboletas, pertencentes a quatro subfam?lias (Biblidinae, Charaxinae, Nymphalinae e Satyrinae). A riqueza, abund?ncia e diversidade variaram em diferentes escalas, principalmente no tempo, sendo maiores na esta??o chuvosa, enquanto a ?-diversidade e turnover foram maiores na seca. A distribui??o das esp?cies seguiu principalmente as mudan?as de umidade, pluviosidade e fenologia vegetacional, n?o havendo limites definidos entre habitats. O per?odo de voo foi compartilhado dentro das subfam?lias, as quais devem ter resposta distinta aos est?mulos ambientais, como tamb?m responder ? fenologia de plantas hospedeiras e ter estrat?gias de reprodu??o distintas. Havendo inclusive, ind?cios de adapta??es fisiol?gicas e comportamentais como reprodu??o sazonal e estiva??o. Portanto, houve controle ambiental sobre a distribui??o e diversidade de esp?cies, com o papel chave da associa??o do clima e estrutura da vegeta??o na diferencia??o da comunidade em esta??es do ano, e da disponibilidade e qualidade de recursos sobre a varia??o de abund?ncia das esp?cies, em pequenas escalas. Tais resultados podem dar suporte ao biomonitoramento e conserva??o de ?reas preservadas, sobretudo em ambientes sob press?o antr?pica e de condi??es ambientais extremas como o semi?rido. / The spatial and temporal distribution of the population reflects the adjustment of their biological characteristics to environmental conditions and biotic interactions as adaptive and phylogenetic precursors elements. The habitat?s heterogeneity and alternating seasons tend to cause patterns of activity of organisms and species diversity. However, these seasonal and spatial patterns in butterfly communities in dry environments are not yet clear. We studied a community of frugivorous butterflies in ESEC Serid?, in northeastern Brazil, aiming to characterize the guild in semiarid and check the relative contribution of climate and vegetation variables on its composition, diversity and phenofaunistic. The butterflies were sampled monthly during one year, and the distribution of species was associated with structural characteristics of three vegetation types (eg. richness and abundance of tree and shrub species, canopy cover, herbaceous cover, litter) and climatological data (temperature, rainfall and humidity). We captured 9580 individuals of 16 species of butterflies belonging to four subfamilies (Biblidinae, Charaxinae, Nymphalinae and Satyrinae). The richness, abundance and diversity varied in different scales, especially in time, being higher in the rainy season, while the ?-diversity and turnover was higher in the dry. The distribution of species mainly followed the changes in humidity, rainfall and vegetation phenology, with no defined boundaries between habitats. The flight period was shared within subfamilies, which should have distinct response to environmental stimuli, as well as respond to the phenology of host plants and have different reproductive strategies. There is even evidence of physiological and behavioral adaptations as seasonal reproduction and aestivation. So there was environmental control over the distribution and diversity of species, with the key role climate Association and vegetation structure in the community of differentiation in the seasons, and the availability and quality of resources on the variation of species abundance in small scales. These results may support the biomonitoring and conservation preserved areas, particularly in environments under human pressure and extreme environmental conditions such as semi-arid.

Abrange uma superf?cie de 370 Km?. A expans?o urbana do munic?pio de Parnamirim tem se desenvolvido de forma muito acelerada sem uma estrutura adequada, notadamente pela aus?ncia de rede esgotos, com riscos de contamina??o das ?guas subterr?neas podendo causar s?rios danos ? sa?de p?blica. As ?guas subterr?neas do Sistema Aqu?fero Barreiras na ?rea de interesse constituem a principal fonte de suprimento h?drico das popula??es urbanas e rurais. O uso da ?gua subterr?nea ? feito sem planejamento adequado e assim, importantes ?reas de recarga est?o sendo ocupadas. O presente estudo foi desenvolvido para a quantifica??o do uso e avalia??o das potencialidades das ?guas subterr?neas, tendo em vista o aumento da oferta de ?gua de boa qualidade e com menores riscos de serem afetadas por atividades contaminantes. Com estes objetivos, foram desenvolvidas as seguintes atividades: cadastro de 268 pontos d??gua; caracteriza??o da litologia, espessuras e estrutura hidrogeol?gica do aqu?fero Barreiras, com base na correla??o de perfis de po?os; e, avalia??o de par?metros hidrodin?micos do aqu?fero, a partir da interpreta??o de resultados de testes de bombeamento de po?os. Verificou-se que a espessura saturada cresce de oeste para leste em dire??o ao mar, com valores que variam de 15,47 a 56,5 m, com m?dia de 32,45 m. Os par?metros hidrodin?micos, obtidos com aplica??o do m?todo de Cooper-Jacob foram: transmissividade m?dia de 5,9x10-3 m?/s e a condutividade hidr?ulica m?dia de 2,82x10-4 m/s. A porosidade espec?fica ? de 15%, obtida com aplica??o da equa??o Biecinski. O mapa potenciom?trico mostra a dire??o principal do fluxo subterr?neo, de oeste para leste, e permite identificar as zonas de recarga correspondentes a regi?o dos tabuleiros do ?Barreiras?.

A Recarga foi estimada em 253 mm/ano, que corresponde ? taxa de infiltra??o de 16,4%. / The study area is within the Pirangi River Basin, eastern sector of Rio Grande do Norte state, where is located of the Parnamirim city. It has an area of approximately 370 km?. Urbanization has developed much fast without an appropriate infrastructure, mainly by the lack of sewage systems, with risks of contamination of groundwater that may cause serious damage to the health of the population. The Barreiras Aquifer System groundwater in the area represents the main source of water supply for urban and rural populations. The use of groundwater occurs without adequate planning and therefore, important recharge areas are being occupied. This study was conducted to quantify the use and evaluation of the potential of groundwater, in order to increase good water quality supply and lower risks of being affected by polluting activities. With these objectives, the following activities were carried out: 268 points of water have been registered; characterization of the lithological, thickness and hydrogeological structure of the Barreiras aquifer, based on the correlation of well logs; and evaluation of hydrodynamic parameters of the aquifer, from the interpretation of results well pumping tests. It was found that the saturated thickness increases from west to east towards the sea, with values ranging from 15,47-56,5 m with an average of 32,45 m. The hydrodynamic parameters using Cooper-Jacob method were: average transmissivity of 5,9x10-3 m?/s and average hydraulic conductivity 2,82x10-4 m/s. The effective porosity is of 15%, obtained by applying Biecinski equation. The potentiometric map shows the main direction of groundwater flow, from west to east, and identifies the recharge areas corresponding to the region of the tablelands of the "Barreiras". The river valleys refer to the discharge areas of the aquifer system. The Recharge was estimated at 253 mm/year, which corresponds to the 16.4% rate of infiltration.

O captopril ? amplamente adaptado para formula??o l?quida em hospitais. Sua estabilidade em meio aquoso ? reduzida, pois sofre oxida??o gerando o dissulfeto de captopril. Com o intuito de garantir a estabilidade do f?rmaco e dosagem precisa, foi desenvolvido um estudo de pr?-formula??o para a obten??o de uma formula??o de captopril em p? para constitui??o de uma solu??o est?vel de uso pedi?trico. A compatibilidade entre o f?rmaco e os poss?veis excipientes foi avaliada atrav?s das an?lises de calorimetria de varredura diferencial (DSC) e o comportamento t?rmico do captopril atrav?s das an?lises termogravim?tica (TG) e t?rmica diferencial (DTA). Em seguida, foram realizados os ensaios de an?lise granulom?trica e das medidas indiretas de fluxo do captopril e dos excipientes. Para estudo em solu??o, foram obtidas diferentes formula??es a partir de planejamento fatorial, em que se variou a concentra??o de EDTA (0,005 e 0,1%) e pH (2,5; 4,0 e 5,5) em ?gua destilada e ?gua mineral, que foram armazenadas a 60?C e analisadas ao longo de doze dias por CLAE para avalia??o da estabilidade do captopril. Nas curvas DSC das misturas de captotpril com os conservantes, a sucralose e o ?cido c?trico, os eventos t?rmicos de cada subst?ncia isolada n?o foram mantidos. Nas demais curvas das misturas bin?rias os eventos correspondentes a cada componente foram preservados, indicando compatibilidade entre as subst?ncias. Foi observada uma grande diferen?a na distribui??o e di?metro m?dio das part?culas e densidade dos agentes tamponantes em compara??o ?s demais subst?ncias, o que pode ocasionar a segrega??o da mistura de p?s. A partir do estudo da estabilidade das solu??es, foi verificado que as vari?veis interferem significativamente (p = 0,05) no teor do captopril, sendo o pH o fator mais relevante. As intera??es entre as vari?veis foram significativas, com maior estabilidade observada em pH pr?ximo a 4,0, maior concentra??o de EDTA e uso de ?gua mineral. Com base nos resultados, pode-se concluir que o desenvolvimento de uma formula??o de captopril est?vel ? vi?vel desde que sejam adotadas medidas estrat?gicas a fim de se evitar a segrega??o dos p?s constituintes da formula??o. / Nowadays, drugs used in children are adapted from solid dosage forms developed for adults. Captopril in solid dosage form is widely adapted in hospitals into a liquid formulation. Its stability in aqueous solutions is reduced because it undergoes oxidation, forming captopril disulfide. In order to ensure a stable and accurate dosage form, a pre-formulation study was developed for obtaining a stable formulation of a powder for preparation of a captopril solution for pediatric use. The compatibility between drug and possible excipients were evaluated by differential scanning calorimetry (DSC) and the captopril thermic behavior, through thermogravimetric analysis (TG) and differential thermal analysis (DTA). Then, particle size and indirect flow measures of captopril and excipients were analyzed. For solution studies, different formulations were obtained through factorial design, varying the EDTA concentration (0.005 and 0.1%) and pH (2.5, 4.0 e 5.5) in distilled and mineral water, which were stored at 60?C and analyzed over twelve days by HPLC to evaluate the stability of captopril. In the DSC curves of captopril mixtures with preservatives, sucralose and citric acid, the isolated thermal events were not maintained. In the other binary mixtures, the events corresponding to each component were preserved in the curves, indicating compatibility between substances. There was a major difference in the distribution and average particles diameters and density of buffering agents in comparison to other substances, which can cause segregation of the powder mixture. From the study of the solutions stability it was found that the variables interfere significantly (p = 0.05) in the captopril content, the pH being the most important factor. The interactions between variables were significant, with greater stability around pH 4.0, higher EDTA concentrations and use of mineral water. Based on the results, it can be concluded that development of a stable captopril formulation is viable if strategic measures are adopted in order to avoid segregation of the powders constituents of the formulation.

This action, spent in a rural settlement in Flor?nia/RN, gets support on a Collab orative Investigation of interpretative/reflective character in which EJA teachers think over conceptions and concepts inscribed in curriculum references rebuilding conceptions concerning their personal identities as EJA rural teachers. We take as guideway the presupposition of two logics influencing the curriculum configuration inside EJA Francisca Leon?sia Cruz Municipal School. On the one hand, the one directed by Education Municipal Department (SME); on the other hand, that other brought about by a social movement (MST), each one based on conflicting political proposals nourished on its own human social right conceptions developed by rural men and women. This work tries to comprehend the tensions and dilemmas of these teachers, their contradictory believes and values put together in the construction of a curriculum proposal. The deadlock faced in the curriculum referential, where principles and models are in dispute, permit to think over a curriculum proposal capable of meeting the exigencies of young and adult students established in a certain space of the public school.

No entanto, as reservas de petr?leo nessas condi??es est?o cada vez mais escassas, surgindo a necessidade operacional de atua??o em condi??es mais severas, ou seja, vem sendo relatada na literatura a necessidade de sistemas aquosos para atua??o em altas temperaturas e altas press?es (ATAP). As altas temperaturas dos po?os de petr?leo favorecem a degrada??o qu?mica dos pol?meros (aditivo comumente presente nas formula??es relatadas, atualmente, na literatura e aplicados em situa??es operacionais), podendo promover a redu??o da massa molar e perdas de viscosidade do sistema.

Neste trabalho, a aplicabilidade de microg?is de hidroxipropilguar (HPG), obtidos por reticula??o do HPG com ?ons borato, foi avaliada quanto ? resist?ncia t?rmica em fluidos de perfura??o aquosos. A aplica??o de microg?is de HPG no fluido de perfura??o base ?gua aumentou a viscosidade aparente e reduziu o volume de filtrado na temperatura ? 25?C. Entretanto, com o aumento da temperatura para 50 ?C ocorreu redu??o da viscosidade aparente de 85 mPa.s para 25,45 mPa.s. Esses resultados indicam que o emprego de microg?is em fluidos de perfura??o aquosos pode ser uma alternativa promissora, desde que o agente reticulante seja adequadamente selecionado, ou seja, n?o sofra desativa??o com o aumento da temperatura e n?o seja influenciado pela salinidade do meio. / Aqueous drilling fluids are a widely used systemin the world to drill oil wells. This drilling system has been being developed excellent formulations for drilling initial sections with low temperature and low pressure in recent decades. However, the oil reserves in these conditions are increasingly scarce, ending up in the need for drilling fluids with better operational performance in the toughest conditions. Therefore, it has been reported in the literature the need for aqueous systems to operate at high temperatures and high pressures (HTHP). High temperatures of oil wells favor the chemical degradation of polymers (commonly reported in additive formulations currently in the literature and applied in operational situations), that can generate molecular weight reduction and viscosity losses. Microgels can be applied in vast industrie`s segments, highlighted in the oil field, as they are used in the estimulation of wells and in the Advanced Oil Recovery (EOR). In this work, the applicability of hydroxypropyl guar`s microgels (HPG), obtained by crosslinking the HPG with borate ions, was measured as the thermal stability in water based drilling fluids.The application HPG microgels in water-based drilling fluid has increased viscosity and the apparent volume of the filtrate reduced around 25 ? C. However, with the increase of temperature to 50 ?C, the viscosity of drilling fluids based on HPG microgels decreased from 85 mPa.s to 25,45 mPa.s. These results indicate that the use of microgels in aqueous drilling fluids is a promising alternative since the crosslinking agent has been properly selected, i.e., does not undergo deactivation with increasing temperature and is not affected by the salinity of the system.

ProEMI NO MARANH?O: necessidades formativas para o desenvolvimento de pr?ticas pedag?gicas inovadoras de professores em escolas p?blicas de S?o Lu?s, vinculado a Linha de Pesquisa: Aprendizagem, Forma??o e Profissionaliza??o Docente, do Programa de P?s Gradua??o da UFRN, teve como problema de pesquisa: O Programa Ensino M?dio Inovador ? ProEMI em S?o Lu?s, desde sua implanta??o em 2009, tem se constitu?do em grandes desafios aos professores, pois traz como um dos pressupostos, a cria??o de ?propostas inovadoras nas escolas?. Este fato tem possibilitado a emerg?ncia de novas necessidades formativas para o desenvolvimento de pr?tica pedag?gicas inovadoras? E como objetivo geral: Analisar necessidades formativas de professores que emergiram no contexto de atua??o do Programa Ensino M?dio Inovador nas escolas p?blicas de S?o Lu?s/MA com vistas ? forma??o continuada para o desenvolvimento de pr?ticas pedag?gicas inovadoras. Para atingir tal prop?sito, optou-se pelo referencial te?rico da concep??o Hist?rico Cultural na teoria da Atividade de Leontiev (1983, 1998) e Vigotsky (2003), como fundamentos principais das an?lises, mantendo-se um constante dialogo com estudiosos dessa teoria e da ?rea de forma??o de professores como Rodrigues e Esteves (1993), N?voa (1995), Carbonell (2002), Ramalho, N??ez e Gauthier (2004), Mu?oz e Hern?ndez (2008), N??ez (2009), Ramalho e N??ez (2011a, 2011b), Marcelo (2013), entre outros. Trata-se de um estudo explorat?rio anal?tico baseado nas abordagens qualitativo/quantitativo, tendo como foco a detec??o, determina??o e prioridade das necessidades formativas dos professores, assim como a identifica??o e caracteriza??o das representa??es mentais sobre pr?tica pedag?gica inovadora para os professores, no referido programa. O instrumento utilizado para coleta dos dados, foi o question?rio com quest?es abertas e fechadas. Os procedimentos utilizados para an?lise dos resultados foram estat?sticas descritivas e an?lise de conte?do de Bardin (2011) As an?lises revelaram que as necessidades formativas apresentadas pelos professores emergiram ao materializarem sua atividade pr?tica profissional docente nos diversos contextos de atua??o do PROEMI. E para os professores, uma pr?tica pedag?gica inovadora pode ocorrer por meio de novas aprendizagens na forma??o continuada, tendo a criatividade, como um dos componentes para o planejamento e desenvolvimento de atividades mais din?micas e criativas no contexto da atividade docente. / This study, called "INNOVATIVE HIGH SCHOOL PROGRAM - IHSP IN MARANH?O: training needs and innovative pedagogical practices of teachers in public schools in S?o Lu?s?, is linked to the research line: Learning, Training and Professional Teaching, as well as the project "innovative high school teachers in RN: beliefs, training needs and pedagogical innovation" developed by the Postgraduate UFRN Program. The problem this research faced was: Since its implementation in 2009 the Innovative High School Program (IHSP) in S?o Lu?s has been facing great challenges to teachers, bringing as one of the requirements, the creation of "innovative proposals in schools." Has this fact warned about the emergence of new training needs for innovative teaching practice? And as a general objective: Conducting a study about the teachers? training needs which emerged in the context of the Innovative High School Program?s performance in public schools in S?o Lu?s / MA aiming continuous education of innovative teaching practices. In order to achieve this objective, we have choosen the theoretical framework of the historical cultural conception in Leontiev?s (1983, 1998) and Vygotsky?s (2003) Theory of Activity, as the main basis of the analysis, keeping a constant dialogue with scholars of this theory and members of the teacher training area as Rodrigues and Esteves (1993), N?voa (1995), Carbonell (2002), Ramalho, N??ez and Gauthier (2004), Mu?oz and Hern?ndez (2008), N??ez (2009), Ramalho and N??ez (2011a, 2011b), Marcelo (2013), among others. It is an analytical exploratory study based on qualitative/quantitative approaches, focusing on identifying and characterizing mental representations of innovative teaching practice, determining and setting the priority for the teachers? training needs in the program. The instrument used for data collection was a questionnaire with open and closed questions. The procedures applied to analysis of the results were descriptive statistics and Bardin content analysis (2011). Throughout the research, the teachers explained that innovative teaching practice can come through further learning in teacher education. According to this view, creativity is one of the components in the planning and development of the most dynamic and creative activities in the framework of teaching practice. The analysis also revealed that the training needs presented by teachers arose from experience of their professional practical activity in several IHSPs performance contexts.

Seu objeto de estudo consiste no redimensionamento do conceito arquiteturas pedag?gicas voltado para o planejamento de professores que utilizam o laptop na sala de aula que tem como objetivo geral compreender as arquiteturas pedag?gicas entendidas como dispositivos de formA??o, a partir dos quais os professores estruturam pr?ticas multiletradas. O conceito de Arquiteturas Pedag?gicas, conforme proposto por Carvalho, Nevado e Menezes (2005), ? compreendido como estruturas de aprendizagem que se realizam na conflu?ncia de abordagens pedag?gicas e tecnol?gicas. Nesse sentido, tomaremos como an?lise os seguintes objetivos espec?ficos: (a) discutir como os professores vivenciam pr?ticas multiletradas a partir do uso de arquiteturas pedag?gicas desenvolvidas durante o planejamento de atividades curriculares, utilizando o laptop e quais os desafios dessa pr?tica; (b) identificar os impactos das arquiteturas pedag?gicas nos modos de ressignificar o espa?o-tempo disciplinado pela escola no trabalho do professor; (c) Apreender os recursos educacionais abertos (REA) por meio dos quais as arquiteturas pedag?gicas, desenvolvidas na forma??o do professor, possibilitam a mobiliza??o de estrat?gias curriculares abertas interessadas na observa??o de como os alunos melhor se engajam em suas atividades escolares, com o laptop. Estes objetivos ser?o realizados dentro da perspectiva dos multiletramentos durante a forma??o de professores que planejam, pesquisam, registram, sistematizam, criam estrat?gias, utilizam tecnologias e avaliam experi?ncias de aprendizagem de seus alunos sob o ponto de vista da Pedagogia da Incerteza (FREIRE, 2002). Propomos como elemento estruturante dessas arquiteturas, a aprendizagem por design de constru??o de sentidos proposto pela Pedagogia dos Multiletramentos (COPE & KALANTZIS, 2000) que estrutura os espa?ostempos culturais do processo ensino e aprendizagem e dos diferentes modos de significar a linguagem mediada pelas tecnologias digitais. Tomamos como referencial te?rico al?m do conceito de arquiteturas pedag?gicas (CARVALHO; NEVADO; MENEZES, 2005), as contribui??es dos Estudos de Letramento (GEE 1991; STREET, 1995), a rela??o estrutura e ag?ncia (ARCHER, 2011), os conceitos de agente de letramento (KLEIMAN, 2006), de mediador agentivo (OLIVEIRA, 2010a) e comunidades de pr?tica (WENGER, 1998). O estudo tem como abordagem metodol?gica a pesquisa-forma??o, proposta por Josso (2009), que se alinha ? perspectiva de pesquisa qualitativa de cunho etnogr?fico, adotando como procedimentos de gera??o dos dados, os instrumentos: observa??o participante, an?lise de documentos, question?rios e entrevistas. A pesquisa tem como contexto a Escola Municipal Prof. Herly Parente, Natal-RN que foi contemplada com a distribui??o de laptops do Projeto UCA e forma??o de seus professores. Tem como colaboradores 16 professores que participaram dessa forma??o, fornecendo relatos e produ??es de suas pr?ticas desenvolvidas na sala, utilizando tecnologias, os quais constitu?ram o corpus da pesquisa. Nossas premissas em torno dos construtos 'Arquiteturas Pedag?gicas? e ?Pedagogia dos Multiletramentos?, buscaram, na forma??o de professores, a concilia??o entre pr?ticas abertas e as j? consolidadas e disciplinadas na escola (OLIVEIRA, 2010b). As an?lises evidenciam que os desafios vivenciados pelos professores em suas pr?ticas, ao desenvolverem arquiteturas pedag?gicas utilizando o laptop, permitiram n?o somente a cria??o de estrat?gias de atividades para que pr?ticas curriculares abertas sejam poss?veis em contexto de ensino tradicional como tamb?m ampliaram os repert?rios de pr?ticas multiletradas desses professores, impactando a sua forma??o. / This research comprises pedagogical architectures as devices of the formation of multiliteracies practices of teachers who have participated of the course of 'Continued Education of Teachers of the Project One Computer Per Student / UCA?, held at the Municipal School Prof. Herly Parente, Natal-RN. Its object of study consists in the redesign of the concept of pedagogical architectures aimed at the planning of teachers who use the laptop in the classroom. The concept of Pedagogical Architectures, as proposed by Carvalho, Nevado and Menezes (2005), is understood as learning structures that take place at the confluence of pedagogical and technological approaches. It will be discussed in the perspective of multiliteracy during the formation of teachers who plan, research, register, systematize, create strategies, use technologies and evaluate their students' learning experiences from the point of view of Uncertainty Pedagogy (FREIRE, 2002). We propose as a structuring element of these architectures, the learning by design of sense construction proposed by the Pedagogy of Multiliteracies (COPE & KALANTZIS, 2000) that structures the cultural spacetime of the teaching and learning process and the different ways of signifying language mediated by digital technologies. We take as theoretical reference beyond the concept of pedagogical architectures (CARVALHO; NEVADO; MENEZES, 2005) The contributions of the Literacy Studies (GEE 1991, STREET, 1995), the structure and agency relationship (ARCHER, 2011), the concepts of the literacy?s agent (KLEIMAN, 2006), agentive mediator (OLIVEIRA, 2010a) and communities of practice (WENGER, 1998). The study has as a methodological approach the research-formation, proposed by Josso (2009), that aligns with the perspective of qualitative research of ethnographic character, adopting as data generation procedures, the instruments: participant observation, analysis of documents, questionnaires and interviews. The research has as context the Municipal School Prof. Herly Parente, Natal-RN that was contemplated with the distribution of laptops by the UCA Project and formation of their teachers. It has as collaborators 16 (sixteen) teachers who have participated in this formation, providing reports and productions of their practices developed in the classroom, using technologies, which have constituted the corpus of the research. Our premises around the constructs 'Pedagogical Architectures' and 'Pedagogy of Multiliteracies', sought, in the formation of the teachers, the conciliation between open practices and those already consolidated and disciplined in the school (OLIVEIRA, 2010b). The analysis show that the challenges faced by teachers in their practices, when they develop pedagogical architectures using the laptop, allow not only the creation of strategies of activities for open curricular practices be possible in the context of traditional teaching, but also to expand the repertoires of multiliteracies practices of these teachers, impacting their formation.

This study was conducted in the states of RJ and MS, although the project is in all states of Brazil and the Federal District, totaling ten thousand units. The research aimed to evaluate the impact of a low-cost social technology with bases agroecological production, systematized in order to organize the integration vegetable animal production in small spaces, using as much as possible locally available materials. In an agricultural setting where pesticide use has intensified and caused the wear of soil and contamination of farmers and consumers, social technology PAIS is to provide small farmers an alternative to the production of healthy food, but at the same time an opportunity to generate income on a growing demand for these products. The methodology of this study used interviews script (step 1) when it sought from the technicians trained by the program with direct management of family production systems, understand the local dynamics in implementing the proposal, identifying the nuances related to the objectives of research and identify relevant production systems, then (step 2), further analysis of successful experiences and failure in the implementation and execution of technology PAIS, seeking improvement in food quality and income of families at social risk through visits to the production units in order to conduct interviews with producers in order to have more information for the study. Finally, in a further step (step 3), visits were made to the sectors of Sebrae participating in the PAIS management in selected states for the consolidation of information. The study revealed that most farmers benefited from the program improved their food with diversified products, completely eliminated the use of synthetic inputs, and in some cases, have obtained organic label. With the conquest of new markets, the sale of surplus production caused the increase in income for most families benefited from the program / O presente trabalho visa avaliar o impacto da tecnologia social PAIS, no que se refere a melhoria na alimenta??o das fam?lias contempladas, assim como a evolu??o da sua renda e a ado??o de pr?ticas agroecol?gicas que vieram junto com a chegada do programa. Esse estudo foi realizado nos estados do RJ e MS, embora o projeto se encontra em todos os estados do Brasil e no distrito Federal, totalizando dez mil unidades. A pesquisa teve como objetivo avaliar os impactos de uma tecnologia social de baixo custo, com bases a produ??o agroecol?gica, sistematizada de forma a organizar a integra??o produ??o animal vegetal em pequenos espa?os, usando o m?ximo poss?vel materiais localmente dispon?veis. Num cen?rio agr?cola onde o uso de agrot?xicos tem se intensificado e provocado o desgaste dos solos e contamina??o dos agricultores e consumidores, a tecnologia social PAIS vem para proporcionar aos pequenos agricultores uma alternativa para a produ??o de alimentos saud?veis, mas ao mesmo tempo uma oportunidade de gerar renda diante de uma demanda crescente por esses produtos. A metodologia desse estudo fez uso de roteiro de entrevistas (etapa 1), quando se buscou junto aos t?cnicos capacitados pelo programa com atua??o direta junto aos sistemas de produ??o familiares, entender a din?mica local na execu??o da proposta, identificando as nuances referentes aos objetivos da pesquisa, bem como identificar sistemas de produ??o relevantes para, em seguida (etapa 2), aprofundar a an?lise das experi?ncias de sucesso e insucesso na implanta??o e execu??o da tecnologia PAIS, na busca de melhoria na qualidade alimentar e da renda de fam?lias em risco social, atrav?s de visitas ?s unidades de produ??o com objetivo de fazer entrevistas com os produtores a fim de ter mais informa??es para o estudo. Finalmente, em uma etapa complementar (etapa 3), foram realizadas visitas aos setores do Sebrae que participavam da gest?o do PAIS nos estados selecionados para consolida??o das informa??es. O trabalho revelou que a maioria dos agricultores beneficiados pelo programa melhorou a sua alimenta??o com produtos diversificados, eliminou totalmente o uso de insumos sint?ticos e, em alguns casos, obtiveram o selo org?nico. Com a conquista de novos mercados, a comercializa??o do excedente da produ??o provocou o aumento da renda para a maioria das fam?lias beneficiadas pelo programa.
