Esses reposit?rios lidam com a produ??o intelectual de uma determinada institui??o, e est?o diretamente ligados as institui??es de ensino superior. Por?m, o ambiente tecnol?gico no qual se inserem ? fr?gil, e exp?e os formatos e suportes ? obsolesc?ncia. Com isso, a preserva??o digital, enquanto conjunto de processos que visa garantir a salvaguarda e acesso de longo prazo a essa produ??o, ganha fundamental import?ncia. Nesse sentido, atua a rede brasileira de servi?os de preserva??o intitulada Rede Cariniana, gerida pelo IBICT. A Rede utiliza o modelo de preserva??o digital distribu?da, operacionalizada atrav?s do software LOCKSS. Com o objetivo de apoiar um acordo de coopera??o entre a UFRN e o IBICT, este estudo prop?s um conjunto de requisitos m?nimos, direcionado para a UFRN e seu reposit?rio institucional, com o intuito de adequ?-lo ? Rede Cariniana, para com isso possibilitar a preserva??o e o acesso de longo prazo ? produ??o da UFRN. O conjunto ? voltado principalmente para a prepara??o dos documentos, visando trat?-los, para que sejam inseridos de forma adequada no reposit?rio e posteriormente incorporados ? Rede Cariniana. Com o conjunto proposto pretende-se apoiar o acordo de coopera??o e tratar a preserva??o digital da produ??o intelectual da UFRN a curto prazo, para que a institui??o possa construir, a m?dio e longo prazo, um Plano de Preserva??o Digital mais ambicioso, ou mesmo um Plano para certifica??o de seu reposit?rio. / Institutional repositories include a technological and service infrastructure that aims to publication, access, use and store information. These repositories handle intellectual production of a given institution, and are directly connected with higher education institutions. However, their technological environment is fragile, and exposes the formats and supports to obsolescence. Therefore, digital preservation, as a set of processes aimed at ensuring the safety and long-term access to this production, gain fundamental importance. ?Rede Cariniana?, the Brazilian network of preservation services managed by IBICT, is committed to solve this problem. The network uses the model of distributed digital preservation, operationalized through the LOCKSS software. With the goal of supporting a cooperation agreement between the UFRN and IBICT, this study proposes a set of minimum requirements, directed to the UFRN and its institutional repository, to tailor the repository to ?Rede Cariniana?, enabling the preservation and long-term access to the intellectual production of UFRN. The requirements concern mainly the preparation of documents, so that they are deposited properly in the repository and subsequently incorporated into ?Rede Cariniana?. The proposed set of requirements is aimed at supporting the working agreement and treat the digital preservation of UFRN intellectual production in the short term, enabling the institution to build, in a medium and long term, a more ambitious digital preservation plan, or a certification plan for its repository.

Pesquisa do estado de Minas Gerais (FAPEMIG) / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior (CAPES) / Conselho Nacional de Desenvolvimento Cient?fico e Tecnol?gico (CNPq) / Pouco conhecimento est? dispon?vel em torno da preval?ncia e dos fatores associados ?s altera??es de mucosa bucal em crian?as pr?-escolares procedentes da zona urbana ou rural. O objetivo do presente estudo foi verificar a preval?ncia e os fatores associados com varia??es da normalidade e les?es de mucosa bucal em 541 pr?-escolares saud?veis da zona urbana e rural do munic?pio de Diamantina, Minas Gerais, Brasil. Atrav?s de question?rio aplicado aos pais/respons?veis investigaram-se informa??es sociodemogr?ficas como proced?ncia da crian?a (zona urbana ou rural), escolaridade da m?e e renda mensal do grupo familiar, al?m da presen?a de h?bitos nocivos como bruxismo, suc??o e mordiscagem de objetos. Em seguida, exames bucais foram realizados para verificar altera??es de mucosa e higiene bucal, al?m da presen?a de c?rie dent?ria. An?lise descritiva, testes Kruskal-Wallis, Mann-Whitney, qui-quadrado, Exato de Fisher e regress?o log?stica multivariada foram utilizados para an?lise dos dados (p<0,05). A preval?ncia de altera??es de mucosa bucal foi de 49,5%. As varia??es da normalidade mais frequentes foram: l?ngua saburrosa (23,4%), manchas mel?nicas (14,4%) e gr?nulos de Fordyce (8,1%). Por outro lado, as les?es mais prevalentes foram: les?es ulceradas (11,8%), queilite angular (3,0%) e f?stula (1,3%). Independentemente do g?nero, idade, escolaridade da m?e, renda familiar e proced?ncia da crian?a, pr?-escolares de 3 a 5 anos possu?ram maior chance de apresentar l?ngua saburrosa [OR:2,55; (IC95%: 1,6-4,1)], manchas mel?nicas [OR:4,07; (IC95%: 2,3-7,2)] e gr?nulos de Fordyce [OR:12,70; (IC95%: 7,2-28,6)]. L?ngua saburrosa foi mais prevalente em crian?as de baixa renda [OR:2,35; (IC95%: 1,3-4,3)] e higiene bucal insatisfat?ria [OR:4,65; (IC 95%: 2,9-7,4)]. Crian?as da zona rural [OR:3,86; (IC 95%: 2,1-7,1)] e do g?nero feminino [OR:2,23; (IC 95%: 1,3-3,8)] apresentaram maior ocorr?ncia de manchas mel?nicas. Pr?-escolares com c?rie possu?ram maior chance de apresentar linha alba [OR: 6,19; (IC95%: 1,1-26,1)], ulcera??es bucais [OR:2,15; (IC95%: 1,2-3,9)] e f?stula [OR:12,0; (IC95%: (1,4-11,3)]. Pr?-escolares com bruxismo apresentaram maior ocorr?ncia de queilite angular [OR:5,55; (IC95%: 1,9-16,3)]. Concluiu-se que a preval?ncia de altera??es de mucosa bucal em crian?as pr?-escolares foi alta. Os fatores mais frequentemente associados ?s varia??es da normalidade foram o g?nero feminino, idade entre 3 e 5 anos, higiene bucal insatisfat?ria, baixa renda familiar, proced?ncia rural e c?rie dent?ria.

The aim of the present study was to determine the prevalence of abnormalities and lesions in the oral mucosa and associated factors among 541 healthy preschool children in urban and rural areas of the city of Diamantina, Minas Gerais, Brazil. A questionnaire administered to parents/guardians investigated socio-demographic variables, such as child?s place of residence (urban or rural area), mother's schooling and monthly household income as well as harmful habits such as bruxism (teeth grinding/clenching), sucking habits and chewing on objects. Oral examinations were performed to determine mucosa alterations, oral hygiene and dental caries. Descriptive analysis, Fisher?s Exact test, the Kruskal-Wallis, Mann-Whitney and chi-square tests and multivariate logistic regression were used for data analysis (p < 0.05). The prevalence of alterations in the oral mucosa was 49.5%. The most prevalent abnormalities were coated tongue (23.4%), melanotic macules (14.4%) and Fordyce granules (8.1%). The most prevalent lesions were oral ulcers (11.8%), angular cheilitis (3.0%) and fistula (1.3%). Preschool children aged three to five years had a greater chance of exhibiting coated tongue (OR: 2.55; 95% CI: 1.6-4.1), melanotic macules (OR: 4.07; 95% CI: 2.3-7.2) and Fordyce granules (OR: 12.70; 95% CI: 7.2-28.6). Coated tongue (OR: 2.35; 95% CI: 1.3-4.3) and poor oral hygiene (OR: 4.65; 95% CI: 2.9-7.4) were more prevalent among low-income children. Children in rural areas (OR: 3.86; 95% CI: 2.1 to 7.1) and the female gender (OR: 2.23; 95% CI: 1.3-3.8) had a higher occurrence of melanotic macules. Preschool children with dental caries had a greater chance of exhibiting linea alba (OR: 6.19; 95% CI: 1.1-26.1), oral ulcers (OR: 2.15; 95% CI: 1.2-3.9) and fistula (OR: 12.0; 95% CI: 1.4-11.3). Children with bruxism had higher incidence of angular cheilitis (OR: 5.55; 95% CI: 1.9-16.3). The prevalence of alterations in the oral mucosa of preschool children was high. The factors most often associated with such abnormalities were the female gender, age between three and five years, poor oral hygiene, low income, residing in a rural area and dental caries. However, the only factors associated with oral mucosa lesions were dental caries and bruxism.

Ambas as les?es apresentam caracter?sticas cl?nicas distintas, apesar de possu?rem caracter?sticas histol?gicas semelhantes. Assim, estudos imunoistoqu?micos em LPCG e LCCG est?o sendo realizados, para permitir um melhor entendimento dessas les?es. Tem sido relatado que a express?o aumentada de FASN e a angiog?nese est?o diretamente ligadas com desenvolvimento dos tumores. No entanto, ainda n?o se sabe se estes eventos est?o envolvidos na patog?nese das LPCG e LCCG. O objetivo deste trabalho foi avaliar a express?o de FASN e o grau de angiog?nese entre LPCG e LCCG, al?m de verificar a correla??o entre essas vari?veis. Assim, 13 casos de LCCG e 14 casos de LPCG foram selecionados para an?lise da express?o imunoistoqu?mica de FASN, CD34, CD105 e D2-40. A express?o de FASN foi avaliada nos componentes celulares da les?o, seguida da mensura??o da densidade microvascular (DMV) e ?rea microvascular (AMV) para cada uma das amostras selecionadas. Os dados coletados foram submetidos ? an?lise descritiva e sequencialmente aos testes de Mann Whitney, teste t para amostras independentes e testes de correla??o de Pearson e Spearman. Os resultados do nosso estudo indicam que: (1) n?o h? diferen?as na imunoexpress?o de FASN entre os grupos de les?es (CM ? 8% FASN+ / CGM ? 38% FASN+); (2) LPCG possuem maior DMV em CD34; n?o houve diferen?as na DMV em CD105 e D2-40 entre as les?es. A AMV em LPCG foi maior que em LCCG para CD34, CD105 e D2-40; (3) em LPCG houve correla??o positiva entre (CM ? FASN+ com DMV/CD105); (4) nas LCCG houve correla??o positiva entre (CM ? FASN+ com DMV/CD105), (CM ? FASN+ com AMV/CD105 e CD34), (CGM ? FASN+ com AMV/CD105). A partir dos resultados obtidos concluiu-se que os n?veis similares da express?o imunoistoqu?mica de FASN indicam processos constitutivos da manuten??o tissular de ambas as les?es. No entanto, as diferen?as na vasculariza??o, entre os grupos de les?es, parecem ser influenciadas por CM positivas para FASN. / Disserta??o (Mestrado) ?

These lesions show distinct clinical features, although they have similar histological characteristics. Thus, immunohistochemical studies in PGCL and CGCL are being done to improve understanding these diseases. It has been reported that high level of FASN and angiogenesis are linked with tumors development. However, remains unknown whether these events are involved in the pathogenesis of LPCG and LCCG. The aim of this research was to study FASN expression and angiogenesis degree between PGCL and CGCL, in addition, verify the correlation between this variables. Thus, 13 cases of CGCL and 14 cases of PGCL were selected and examined by immunoexpression of FASN, CD34, CD105 and D2-40. The immunoexpression of FASN was assessed in components cells of lesions, followed by measurement of Microvassel Density (MVD) and Microvassel Area (MVA) for each selected sample. Data collected was submitted to descriptive analysis and followed by Mann Whitney test, ?t? test to independent samples and Person?s and Spearman?s correlation. The results of this study indicate that: (1) there are no differences in FASN immunoexpression between group lesions (MC ? 8% FASN+ / MGC ? 38% FASN+); (2) PGCL have greater MVD in CD34 than CGCL; there are no MDV differences in CD105 and D2-40 between lesions. PGCL have greater MVA in CD34, CD105 and D2-40 than CGCL; (3) in PCGL there was a positive correlation between (MC ? FASN+ and MVD/CD105); (4) in CGCL there was a positive correlation between (MC ? FASN+ and MVD/CD105), (MC ? FASN+ and MVA/CD105 and CD34), (MGC ? FASN+ and MVA/CD105). With base on these results it is concluded that similar expression of FANS levels indicate constituent process of tissue maintenance in both lesions. On the other hand, differences on angiogenesis between lesions seem be influenced by FASN+ mononuclear cells.

O estudo foi conduzido em ?reas de reserva legal de propriedades particulares no munic?pio de Presidente Juscelino (MG), nas coordenadas 18?38?40?S e 44?04?57?W, com altitudes variando entre 600 e 890 m. O remanescente possui aproximadamente 150 ha, com relevo c?ncavo e declividades acentuadas. Foram observadas por??es ?reas com alto grau de dist?rbios antr?picos. H? evid?ncias de corte raso em uma faixa de vegeta??o, assim como de corte seletivo de algumas esp?cies de interesse comercial. Destaca-se tamb?m a exist?ncia de dist?rbios como, a alta compacta??o do solo gerada pela entrada de gado em algumas parcelas, clareiras naturais e antr?picas; solo exposto e trilhas ao longo do fragmento. Para o invent?rio florestal foram alocadas 25 parcelas permanentes de 20 ? 20 m (400 m?), totalizando ?rea amostral de 1 hectare. Nestas foram amostrados todos os indiv?duos arb?reos com circunfer?ncia ? altura do peito (CAP) > 15,7 cm, exceto lianas e indiv?duos mortos. As esp?cies amostradas foram classificadas em cinco sistemas de guildas (grupo ecol?gico, dispers?o, poliniza??o, toler?ncia ? desseca??o e densidade da madeira), a fim de formar grupos funcionais. Para a avalia??o das rela??es entre as vari?veis ambientais e a distribui??o do compartimento arb?reo, foram coletadas aleatoriamente no interior de cada parcela cinco amostras simples do solo superficial (0?20 cm), com cerca de 500 g de solo. Al?m do solo foram coletadas vari?veis de relevo, dossel e matriz de impacto (natural e antr?pico). Estas foram submetidas a uma An?lise dos Componentes Principais (PCA), onde apenas cinco das 28 vari?veis iniciais apresentaram alta correla??o: Calc?rio (Ca); Pot?ssio (k); Argila; rocha exposta e mat?ria org?nica. Tr?s das cinco esp?cies de maior valor de import?ncia apresentaram distribui??es diam?tricas relacionados com efeitos de resposta p?s-dist?rbio e a caracter?sticas da pr?pria esp?cie. Foi verificado um alto valor de H?, o que indica uma ?rea com diversidade relativamente alta e um baixo valor para J? e uma forte domin?ncia ecol?gica de esp?cies. Os resultados da an?lise de parti??o da vari?ncia a partir dos modelos de regress?o m?ltipla feita para cada eixo da an?lise NMDS mostraram que a distribui??o da vegeta??o est? altamente correlacionada com a estrutura espacial e ? influenciada em parte pelas vari?veis ambientais argila e mat?ria org?nica. A an?lise de classifica??o Twinspan definiu quatro grupos distintos entre as esp?cies avaliadas os quais se diferenciaram em rela??o ?s suas fun??es ecol?gicas. A compara??o da participa??o dos grupos de ordena??o da NMDS em rela??o aos grupos funcionais de classifica??o Twinspan, mostrou que a ?rea estudada apresenta um padr?o funcional dominado por esp?cies pioneiras a secund?rias iniciais, com dispers?o anemoc?rica e germina??o ortodoxa. O fragmento estudado encontra-se em um est?dio inicial de sucess?o secund?ria, onde as diferentes estrat?gias ecol?gicas das esp?cies ocuparam posi??es distintas ao longo do fragmento, apresentando tend?ncias adaptativas das esp?cies as condi??es do ambiente. Os resultados refor?am a hip?tese da grande import?ncia de conserva??o deste fragmento de Floresta Estacional Decidual. / Disserta??o (Mestrado) ?

The study was conducted in areas of legal reserve of private properties in the municipality of President Juscelino (MG), at coordinates 18 ? 38'40 "S and 44 ? 04'57" W, with altitudes ranging between 600 and 890 m. The remainder has approximately 150 ha, with concave topography and steep slopes. Portions were observed areas with a high degree of human disturbance. There is evidence of clear-cutting in a strip of vegetation, as well as selective logging of some species of commercial interest. Also noteworthy is the existence of disorders such as high soil compaction caused by the entry of cattle in some parts, natural and anthropogenic clearings, exposed soil and trails along the fragment. For the forest inventory were allocated 25 permanent plots of 20 ? 20 m (400 m?), a total sample area of ??1 hectare. These were all sampled trees with circumference at breast height (CAP)> 15.7 cm, except lianas and dead individuals. The sampled species were classified into five systems guilds (ecological group, dispersion, pollination, desiccation tolerance and density of the timber) to form functional groups. To assess the relationships between environmental variables and distribution of tree compartment were collected randomly within each plot five single samples of surface soil (0-20 cm), with about 500 g of soil. Apart from the soil were collected relevant variables, canopy and impact matrix (natural and man-made). These were submitted to a Principal Component Analysis (PCA), where only five of the 28 initial variables were highly correlated: Limestone (Ca), Potassium (k), Clay, exposed rock and organic matter. Three of the five species of greatest importance value showed diameter distributions related to effects of disorder and post-response characteristics of the species itself. There was a high value H ', which indicates an area with relatively high diversity and a low value for J' and a strong predominance ecological species. The results of analysis of variance partitioning from the multiple regression models made for each shaft NMDS analysis showed that the distribution of vegetation is highly correlated with the spatial structure and is partly influenced by environmental clay and organic matter. The classification analysis Twinspan identified four distinct groups among the studied species which differ in relation to their ecological functions. The comparison of the participation of groups of NMDS ordination in relation to the functional group classification Twinspan showed that the study area presents a functional pattern dominated by pioneer species to early secondary, with orthodox anemochoric and germination. The fragment is studied in an early stage of secondary succession, where the different ecological strategies species occupied different positions along the fragment, present trends adaptive species environmental conditions. The results reinforce the hypothesis of the importance of conservation of this fragment Deciduous Forest.

A turfeira pode ser definida como um substrato constitu?do por restos de vegetais mortos, em diferentes est?gios de decomposi??o, que se acumulam em sucess?o em lugares ?midos ou encharcados onde haja uma consider?vel redu??o na atividade biol?gica devido ?s in?spitas condi??es do meio. ? formada pelo ac?mulo em sucess?o de restos vegetais, em locais que apresentam condi??es que inibem a atividade de microrganismos decompositores, como excesso de umidade, baixo pH, escassez de oxig?nio e temperaturas amenas. Outro papel importante reservado para as turfeiras ? sua utiliza??o como arquivo ambiental e cronol?gico da evolu??o das paisagens, das mudan?as clim?ticas e da deposi??o atmosf?rica de metais pesados, em escala regional ou mesmo global. O objetivo deste trabalho foi mapear as turfeiras da por??o norte da SdEM, determinar seu estoque de mat?ria org?nica armazenada e utilizar is?topos de carbono para identificar mudan?as ambientais regionais que ocorreram no Quatern?rio. Turfeiras pr?-selecionadas foram mapeadas atrav?s de trabalhos de campo e de t?cnicas de geoprocessamento e sensoriamento remoto, utilizando os softwares Arcgis 9.3, Envi 4.5 e GPS Trackmaker Pro. A caracteriza??o dos organossolos foi realizada de acordo com metodologia preconizada no Sistema Brasileiro de classifica??o de Solos. Amostras foram enviadas para determina??o da composi??o isot?pica (?13C) e data??es radiocarb?nicas (14C) por espectrometria de cintila??o l?quida de baixa radia??o de fundo. Numa primeira aproxima??o foi poss?vel mapear 14.287,55 hectares de turfeiras distribu?das ao longo de 1.180.109 hectares da SdEM, o que representa 1,2% da ?rea total. Essas turfeiras ocupam um volume m?dio de 170.021.845,00 metros c?bicos, armazenam 4.488.576,71 toneladas de mat?ria org?nica e acumulam em m?dia 314,16 t ha-1. A maioria das turfeiras mapeadas segue o seguinte padr?o ambiental: ocorrem em ?reas aplainadas da superf?cie S2, tendo em sua base rochas quartz?ticas, entre 1100 e 1350 metros de altitude, onde as temperaturas e precipita??es anuais m?dias s?o respectivamente menores que 19?C e maiores que 1200 mm e est?o colonizadas por vegeta??o campestre, com esparsos cap?es de mata. Nas turfeiras da SdEM predominam os est?gios de decomposi??o da mat?ria org?nica avan?ado (s?prico), seguido do intermedi?rio (h?mico). A taxa de crescimento vertical variou entre 0,058 e 0,43 mm ano-1, enquanto a taxa de ac?mulo de carbono oscilou entre 0,95 e 53,91 g m-2 ano-1. As turfeiras que se situam em posi??es altim?tricas de 1.000 a 1.200m e acima de 1.700 m s?o mais recentes (Holoc?nicas), ao passo que aquelas que ocupam posi??es entre 1.200 e 1.700 metros de altitude s?o mais antigas (Pleistoc?nicas). As turfeiras da SdEM, come?aram a ser formadas no Pleistoceno Superior (42.175? 3390 anos A.P.), quando estavam colonizadas predominantemente por plantas de ciclo fotossint?tico CAM. A vegeta??o foi mudando gradativamente para plantas do ciclo fotossint?tico C3 ao longo da transi??o Pleistoceno-Holoceno, processo associado a mudan?as paleoclim?ticas. Atrav?s de mapeamentos via t?cnicas de geoprocessamento e sensoriamento remoto foi poss?vel entender melhor a natureza geol?gica, geomorfol?gica e hidroclimatol?gica das turfeiras e sua inser??o na paisagem regional. Os ambientes turfosos da SdEM guardam significativa import?ncia no armazenamento de carbono org?nico e ?gua e enquanto testemunho de mudan?as paleoambientais, o que fundamenta uma necessidade urgente e emergente no sentido de proporcionar maior prote??o e preserva??o a esses pedoambientes. / Disserta??o (Mestrado) ?

A disserta??o foi estruturada em quatro cap?tulos. O primeiro refere-se ? revis?o bibliogr?fica visando o entendimento dos conceitos que foram abordados no estudo. No segundo capitulo, a influ?ncia do composto no substrato foi avaliada por meio das altera??es nos atributos qu?micos (pH, mat?ria org?nica (MO), soma de bases (SB), CTC, satura??o por bases (V), f?sforo (P), pot?ssio (K), c?lcio (Ca2+), magn?sio (Mg2+), acidez troc?vel (Al3+), acidez potencial (H + Al) e satura??o por alum?nio (m)) e f?sicos (resist?ncia mec?nica a penetra??o (Rp) e granulometria) do substrato. Foi avaliada tamb?m a atividade microbiana: carbono da biomassa microbiana (CBM) respira??o microbiana (C-CO2) e quociente metab?lico (qCO2) ap?s aplica??o de cinco tratamentos: sem aplica??o de composto org?nico e diferentes concentra??es 0,0; 4,5; 9,0; 18,0 e 36,0 g dm-3 por cova. O delineamento foi sistem?tico tipo ?leque? sendo os tratamentos dispostos em tr?s blocos casualizados. A adi??o do composto proporcionou o aumento nos valores de pH, MO, SB, CTC, V e nutrientes (P, K, Ca2+ e Mg2+) e promoveu a redu??o de Al3+, H + Al e m. O substrato minerado apresentou valores elevados de Rp indicando a compacta??o na ?rea degradada pela extra??o de cascalho, mesmo ap?s a aplica??o do composto. A adi??o de doses crescentes do composto promoveu o aumento significativo de CBM e C-CO2 ao substrato minerado. O maior valor de qCO2 indicou efici?ncia da biomassa microbiana com a incorpora??o das menores doses do composto ao substrato quando comparado ao controle. O terceiro cap?tulo refere-se ao estudo do crescimento das esp?cies nativas Kielmeyera lathrophyton Saddi (Pau santo), Plathymenia reticulata Benth (Vinh?tico), Dalbergia miscolobium Benth (Jacarand? do cerrado) e Bowdichia virgilioides Kunth (Sucupira-preta) plantadas em delineamento sistem?tico tipo ?leque? submetidas a cinco tratamentos: sem aplica??o de composto org?nico e diferentes doses de composto 0,0; 4,5; 9,0; 18,0 e 36,0 g dm-3 por cova dispostos em tr?s blocos casualizados. Ap?s 12 meses, verificou-se que n?o houve diferen?a significativa entre os tratamentos para sobreviv?ncia e incremento em altura, di?metro e cobertura de copa para cada esp?cie. Ainda, de forma preliminar foi poss?vel determinar que a adi??o de 4,5 g dm-3 de composto na cova proporcionou maiores valores de incremento em altura, di?metro e cobertura de copa para Plathymenia reticulata e Bowdichia virgilioides. No quarto cap?tulo, foi realizado o plantio em linha de Chamaecrista debilis submetida a quatro tratamentos, 0,0; 30,0; 60,0 e 120,0 g dm-3 de composto como adubo por cova, dispostos em tr?s blocos casualizados. Os resultados indicaram que n?o houve diferen?a significativa entre as doses de composto aplicado para incremento em altura, di?metro e cobertura de copa. O maior valor de incremento em altura e cobertura de copa ocorreu sem a adi??o de composto de res?duo org?nico de ind?stria de fia??o e tecelagem e para di?metro com a aplica??o de 60,0 g dm-3, no entanto, ? necess?ria a realiza??o de avalia??es futuras. A taxa de sobreviv?ncia apresentou decr?scimo significativo com a aplica??o das maiores dosagens de composto org?nico.

The dissertation was structured in four chapters. Being the first, regarding the bibliographical revision seeking the understanding of the concepts and theoretical questions of what was borded in the study. In the second I chapter, the influence of the compound in the substratum was evaluated through the alterations in the chemical attributes (pH, organic matter (MO), sum of bases (SB), CTC, saturation for bases (V), match (P), potassium (K), calcium (Ca2+), magnesium (Mg2+), exchangeable acidity (Al3+), potential acidity (H + Al) and saturation for aluminum (m)) and physical (mechanical resistance the penetration (Rp) and texture) of the substratum. As well as in the microbial activity of the same: carbon of the microbial biomass (CBM) microbial breathing (C-CO2) and metabolic quotient (qCO2) after application of five treatments: without application of organic composition and different concentrations 0; 4,5; 9,0; 18,0 and 36,0 g dm-3 for hole. The delineation was systematic type "fan" being the treatments disposed in three blocks unexpected. The addition of the compound stimulated the increase in the pH values, MO, SB, CTC, V and nutritious (P, K, Ca2+ and Mg2+) and it promoted the reduction of Al3+, H + Al and m. The mined substratum presented high values of Rp indicating the compactation in the area degraded by the gravel extraction, even after the application of the composed. The addition of growing doses of the compound promoted the significant increase of CBM and C-CO2 to the mined substratum. The largest qCO2 value indicated efficiency of the microbial biomass with the incorporation of the smallest dosages of the compound to the substratum when compared to the control. The third chapter, refers to the study of the growth of the native species Kielmeyera lathrophyton Saddi (sacred Wood), Plathymenia reticulata Benth (Vinh?tico), Dalbergia miscolobium Benth (Jacaranda of the Thicket) and Bowdichia virgilioides Kunth (Sucupira-black) planted in delineation systematic type " fan " submitted to five treatments: without application of organic composition and different doses of compound 0,0; 4,5; 9,0; 18,0 and 36,0 g dm-3 for hole disposed in three blocks unexpected. After 12 months, it was verified that there was not significant difference among the treatments for survival and increment in height, diameter and top covering for each species. Still, in a preliminary way it was possible to determine that the addition of 45 g dm-3 of compound of organic residue of textile industry in the hole stimulated larger increment values in height, diameter and top covering for Plathymenia reticulata and Bowdichia virgilioides. In the fourth chapter, the planting was made in line of Chamaecrista debilis submitted to four treatments, 0,0; 30,0; 60,0 and 120,0 g dm-3 compound dm-3 as fertilizer for hole, disposed in three blocks inexpected. The results indicated that there was not significant difference among compound applied for increment in height and diameter. The largest increment value in height and diameter happened without the addition and with the application of 60,0 g dm-3 of compound of organic residue of textile industry, however it is necessary the accomplishment of future evaluations. The survival rate presented significant decrease with the application of the largest doses of organic compund. The species Chamaecrista debilis presented important characteristics for recovery of degraded area, as fast growth and biomass production.

Two experiments were conducted. With the first experiment was aimed to select genotypes of sweet potato with best features of production of branches and assess the chemical composition of branches wilted sweet potato and its silages. The experiment was conducted at the Fazenda Rio Manso of the UFVJM in the city of Couto Magalh?es de Minas ? MG - Brazil. We used a randomized block design, with fifteen genotypes of sweet potato: BD-31TO, BD-26, BD-13, BD-17, BD-22, BD-24, BD-54, BD-56, BD-69, BD-43, BD-44, BD-46, BD-52, BD-35 and the commercial cultivar Brazl?ndia Rosada, with three replications. Only the number of leaves per linear meter no significant differences were observed among genotypes. Most genotypes has medium to high productivity of green mass (PGM) and dry mass of branches. Due the correlation between the length of the main branch (CB) and productivity of dry mass of branches (PDM), can in future studies to measure the length of the rod aiming higher PDM. No significant differences were observed among genotypes for soluble carbohydrates from branches and wilted silages of branches. Significant differences were found for dry matter (DM), ash, crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF) and lignin. For the wilted branches, genotypes BD-26, BD-13, BD-56, BD-46, BD-35 and Brazl?ndia Rosada presented better compositions bromatologic. The number of leaves in the culture of sweet potato has no relation with the chemical quality of their branches. For silages of branches, genotype BD-56 have the best qualitative characteristics. The second experiment aimed to evaluate characteristics of root yield, composition of silages of roots and the potential production of crude protein of sweet potato genotypes. We used a randomized block design with ten treatments and two replications, and the sweet potato genotypes from the germplasm bank of UFVJM (BD-31TO, BD-17, BD-22, BD-24, BD-54 , BD-69, BD-43, BD-46, BD-52, BD-35). The plots were composed of two piles of 3.0 m, with 0.90 m between furrows and 0.30 m between plants. At harvest, the characteristics evaluated were total root yields (TRY) and marketable yield of roots (MYR), no differences were observed among genotypes these characteristics. The TRY and MYR were low, below the national average. For the average levels of DM, ammonia nitrogen (% N-NH3.NT-1), NDF and lignin were no significant differences between genotypes. The genotypes BD-17, BD-69 and BD-46 showed the best results of composition of silages roots.

Isso se deu pelo fato de n?o ensinarem somente ferramentas b?sicas contidas nos computadores, mas tamb?m os fundamentos da Ci?ncia da Computac?o e como eles podem ser aplicados no dia-a-dia. No Brasil praticamente n?o h? ensino de computac?o nas escolas. Com o objetivo de estimular a inserc?o da computac?o na educac?o b?sica do Brasil, este trabalho apresenta v?rias ferramentas de ensino e aprendizagem de programac?o. Discute como essas ferramentas podem ajudar os alunos a desenvolverem caracter?sticas e conhecimentos desej?veis, tanto para a pr?pria computac?o quanto na sua interdisciplinaridade. ? realizada uma an?lise sobre as caracter?sticas de duas dessas ferramentas: Blockly e App Inventor. Al?m disso, s?o apresentados exemplos de uso. Mostra tamb?m uma reflex?o sobre a import?ncia de trabalhar e desenvolver o pensamento cr?tico e o racioc?nio l?gico dos alunos atrav?s da l?gica de programac?o inserida nas escolas. Foi proposto nesta dissertac?o o desenvolvimento de uma plataforma que re?na as principais ferramentas e oriente os alunos e professores sobre como us?-las. Este trabalho busca contribuir para escola, alunos e professores, apresentando ferramentas de ensino que interajam com crian?as e adolescentes, de forma a proporcionar divers?o e estimular a curiosidade. / Disserta??o (Mestrado Profissional) ?

This is due by the fact they are not teaching only basic computers tools, but also computer science fundaments and how they can be applied in their daily life. In Brazil, there is practically no computer science education in schools. With the aim of motivate the insertion of computing science in Brazil?s basic education, this work presents several teaching and learning tools for computer programming. It discusses how these tools can help students to develop characteristics and knowledge desirable, for their own programing skills and also in their interdisciplinary. An analysis is performed on the characteristics of two tools: Blockly and App Inventor. In addition, their usage examples are provided. It also shows a reflection on the importance of developing the student critical and logical thinking using programming logics inserted in schools. It was proposed in this dissertation the development of a platform that brings together the main tools and guides students and teachers on how to use them. This work aims to contribute to school, students and teachers, presenting teaching tools which interacts with children and teenagers, in order to provide fun and stimulate curiosity.

Tem como objetivo caracterizar a interdisciplinaridade no ?mbito do referido curso tomando como base: as propostas do Programa de Reestrutura??o e Expans?o das Universidades Federais (REUNI), os Referenciais Orientadores para os Bacharelados Interdisciplinares e Similares e os estudos realizados por autores da ?rea relacionados ?s caracter?sticas dessa metodologia de ensino. Procedeu-se a an?lise por meio de pesquisas bibliogr?fica, documental e de campo. As informa??es delas decorrentes, ap?s serem estudadas e integradas, nortearam a elabora??o de propostas e sugest?es de adequa??o do Projeto Pedag?gico do Curso (PPC) e de inser??o de novas pr?ticas did?ticas e pedag?gicas visando contribuir para a efetiva??o da interdisciplinaridade no processo ensino-aprendizagem. Com a realiza??o do levantamento bibliogr?fico foi poss?vel reunir um conjunto importante de informa??es que promoveu o embasamento das pesquisas documental e de campo. A pesquisa documental consistiu na an?lise do PPC juntamente com a estrutura curricular. Atrav?s dela verificou-se que no corpo desses documentos, mesmo sendo feita refer?ncia ? necessidade e import?ncia da interdisciplinaridade na realiza??o das atividades acad?micas, n?o existem caracter?sticas e previs?o de a??es que induzam ou inspirem um trabalho interdisciplinar. Com a pesquisa de campo, que consistiu na aplica??o de question?rio a alunos matriculados no quinto e sexto per?odos e na realiza??o de entrevista junto a professores do curso, procedeu-se a reuni?o de informa??es sobre o contexto analisado no que se refere ao desenvolvimento de pr?ticas interdisciplinares e a aspectos que dificultam ou que contribuem para isso. Foi verificado que, de um modo geral, a metodologia interdisciplinar n?o permeia o planejamento e execu??o das atividades de ensino-aprendizagem do curso. Diante disso, ? eminente a necessidade de que sejam previstas a??es que promovam a inser??o dessa metodologia no desenvolvimento das disciplinas visando a forma??o de egressos baseada no perfil esperado e nos objetivos e princ?pios que regem essa modalidade de ensino. / Disserta??o (Mestrado Profissional) ?

It aims to characterize interdisciplinarity of the course on focusing the following basis: the proposals of the Programme of Restructuring and Expansion of Federal Universities (REUNI), the Guiding Professors for Interdisciplinary and Similar Bachelor degrees and the studies made by authors related to the characteristics of this teaching methodology. The analysis was done by means of bibliographic research, documentary and field. The information resulting from them, after being studied and integrated, guided the preparation of proposals and fitting suggestions of the Pedagogical Project of the Course (PPC) and insertion of new didactic and pedagogical practices to contribute to the realization of interdisciplinarity in the teaching-learning process. With the completion of the bibliographic research, it was possible to gather an important set of information that promoted the foundation of the documentary and field research. The documentary research was the PPC analysis along with the curriculum. Through this research it was found that in these documents, even with reference to the need and importance of interdisciplinarity in carrying out academic activities, there aren't features and prediction of actions that induce or inspire an interdisciplinary work. With the field survey, which consisted of a questionnaire to students enrolled in the fifth and sixth terms and conducting interviews with the professors of the course, it was proceeded the gathering information about the context analyzed in relation to the development of interdisciplinary practices and aspects that hinder or contribute to it. It was found that, in general, the interdisciplinary methodology does not permeate the planning and execution of teaching-learning course activities. Therefore, it is quite important the need to be provided some actions that promote the inclusion of this methodology in the development of the subjects for the training of graduates based on the expected profile and on the goals and principles that conduct this type of education. / . . . .

No. of bitstreams: 1 BeneditaMGC_TESE.pdf: 2605116 bytes, checksum: d46e59abd294480d5e8cc02148c2148d (MD5) Previous issue date: 2012-04-17 / The starting point of the present work consisted of investigating the development of biotechnology in the Northeast region of Brazil from the perspective of a Regional Innovation System (RIS). The theoretical framework adopted relied on the approaches and concepts presented by the Neo-Schumpeterian perspective. This framework was chosen because, by means of the Innovation System concept, this literature allows us to analyze the relationships and configurations of actors, as well as the role of the state and of social, science and technology, and economic policies in the studied region. The analysis considered four selected dimensions: physical infrastructure, human capital, scientific production, and funding. These variables were chosen because they allow us to verify the possibilities and limitations of developing a biotechnology RIS in the Northeast of Brazil, and these elements would help in answering the question behind this dissertation. The location of the physical infrastructure was determined by means of bibliographic and documental research and interviews with heads of institutions that do biotechnology research. Regarding human capital, the analysis focused on resource training in biotechnology, highlighting graduate courses and research groups in the area. To measure knowledge production, we delimited scientific collaboration among researchers in the field of biotechnology as the focus of this category. For the funding dimension, information was gathered from reports available at the websites of national and state funding agencies. The data was analyzed through method triangulation, involving quantitative and qualitative research stages. To back the analyses, we revisited the integration policies in the area of Science, Technology and Innovation. Our analysis has shown that these policies play a crucial role in the development of biotechnology in the region being studied. The data revealed that the physical infrastructure is concentrated in only three states (Bahia, Cear?, and Pernambuco). In this regard, the Northeast Biotechnology Network (Renorbio) stands out as a strategic actor, enabling states with poor infrastructure to develop research through partnerships with institutions located in another state. We have also verified that the practices involving human resource training and knowledge production are factors that enable the emergence of a regional system for biotechnology in the studied region. As limitations, we have verified the low immersion level of regional actors, the heterogeneity of socioeconomic indicators, the lack of financial resources, and a low innovation culture in the business sector. Overall, we have concluded that the development of a Regional Innovation System in Biotechnology, based on the current regional dynamics, depends on an effective change in the behavior of the social agents involved, both in the national and regional dimensions as well as in the public and private spheres / O ponto de partida do presente trabalho consistiu em investigar o desenvolvimento da biotecnologia no Nordeste brasileiro na perspectiva de um Sistema Regional de Inova??o (SRI). Assim, o marco te?rico adotado consistiu nas abordagens e conceitos apresentados pela corrente neoschumpeteriana. A escolha ocorreu em fun??o de a literatura possibilitar, mediante o conceito de sistema de inova??o, a an?lise de rela??es e as configura??es de atores, bem como do papel do Estado e das pol?ticas sociais, de ci?ncia e tecnologia e econ?micas na Regi?o em estudo. A an?lise ocorreu mediante a elei??o de quatro dimens?es: infraestrutura f?sica, capital humano, produ??o cient?fica e financiamento. A escolha destas vari?veis ocorreu em fun??o de elas possibilitarem verificar as possibilidades e limites de desenvolvimento de um SRI em biotecnologia no Nordeste brasileir, elementos que permitem responder ao questionamento norteador desta tese. A localiza??o da infraestrutura f?sica ocorreu mediante pesquisa bibliogr?fica, documental e entrevistas com coordenadores de institui??es voltadas para o desenvolvimento de pesquisas em biotecnologia. Capital humano - a an?lise incidiu sobre a forma??o de recursos em biotecnologia, destacando-se os cursos de p?s-gradua??o e grupos de pesquisas na ?rea. Para mensurar a produ??o do conhecimento delimitamos como foco dessa categoria a colabora??o cient?fica entre pesquisadores na ?rea de biotecnologia. Quanto ? dimens?o: financiamento, as informa??es foram coletadas junto a relat?rios disponibilizados nos sites de ag?ncias financiadoras de ?mbito nacional e estadual. Os dados foram analisados mediante a triangula??o de m?todos, envolvendo etapas das pesquisas quantitativas e qualitativas. Para subsidiar as an?lises revisitamos as pol?ticas de integra??o na ?rea de Ci?ncia, Tecnologia e Inova??o. A an?lise possibilitou verificar que estas pol?ticas desempenham papel essencial para o desenvolvimento da biotecnologia na Regi?o em estudo. Os dados revelaram que a infraestrutura f?sica apresenta concentra??o em apenas tr?s estados (Bahia, Cear? e Pernambuco). Nesse aspecto, a Rede Nordeste de Biotecnologia (Renorbio) surge como ator estrat?gico por possibilitar que estados com baixa infraestrutura desenvolvam pesquisas em parcerias com institui??es localizadas em outro estado. Verificamos, tamb?m, que as pr?ticas voltadas para a forma??o em recursos humanos e produ??o do conhecimento apresentam-se como fatores que possibilitam a emers?o de um sistema regional em biotecnologia em biotecnologia na Regi?o em estudo. Como limita??es, verificamos a baixa imers?o entre atores regionais, heterogeneidade nos indicadores socioec?micos, escassez de recursos financeiros e baixa cultura para inova??o por parte do setor empresarial. De forma geral, conclu?mos que o desenvolvimento de um sistema regional de inova??o em Biotecnologia, tomando-se como base a atual din?mica regional, depende de uma efetiva mudan?a de comportamento dos agentes sociais envolvidos, tanto nas dimens?es nacionais e regionais, como p?blicas e privadas
