Levando em conta as transforma??es sociais ocorridas em rela??o ao parto e assist?ncia obst?trica nas ?ltimas d?cadas, procuro analisar os aspectos que permeiam a atua??o das parteiras em suas comunidades, onde o papel desempenhado por elas vai al?m do partejar. Abordando suas trajet?rias, os conflitos com o sistema formal de sa?de, o di?logo com institui??es governamentais e a incorpora??o de novas concep??es sobre o exerc?cio, elaboro minhas considera??es sobre a pr?tica, numa perspectiva antropol?gica. E nesse sentido, direciono minhas impress?es sobre uma atua??o que longe de mostrar-se cristalizada nos saberes populares, revela-se flex?vel ao incorporar elementos de outras pr?ticas e concili?-los ? sua. Logo, ? essa aproxima??o entre o que ? considerado moderno e tradicional que marca a pr?tica recente das parteiras, cuja configura??o ? perpassada por diversos aspectos e rela??es de poder que, direta ou indiretamente, definem sua configura??o e seu espa?o concreto de atua??o. / The aim of this work is to understand how unofficial obstetric practices have formed in the municipality of S?o Gon?alo do Amarante, Rio Grande do Norte state, Brazil. Considering the social changes that have occurred in the relationship between childbirth and obstetric assistance in recent decades, I seek to analyze aspects seen across the activities of midwives in their own communities today, where the role they play goes beyond childbirth. Addressing their career development, conflicts with the formal health system, dialogue with governmental institutions and the incorporation of new concepts of exercise, I aim to work on devising practical considerations in an anthropological perspective. Therefore, I will focus this dissertation on the work of midwives, something that is not only learned from popular knowledge, but is also sufficiently flexible to be able to incorporate elements of other practices and reconcile them with each other. Thus, it is that coming-together of what is considered modern and traditional that marks the recent practice of midwives, whose work brings together several aspects and power relationship that, directly or indirectly, define that configuration and the concrete space it occupies.

O presente trabalho foi dividido em tr?s cap?tulos. Os objetivos foram avaliar os coeficientes de utiliza??o biol?gicos (CUB?s) dos nutrientes pelo eucalipto, a efici?ncia e possibilidade de utiliza??o das redes neurais artificiais (RNA) para obter os CUB?s e estimativas para a biomassa de tronco sob diferentes espa?amentos. O experimento foi instalado em dezembro de 2002 utilizando-se um h?brido de Eucalyptus grandis W. Hill ex Maiden x Eucalyptus camaldulensis Dehnh sobre Latossolo Vermelho-Amarelo em relevo plano a 1097 m altitude. Adotou-se o delineamento em blocos ao acaso sendo estudado, em tr?s blocos, o efeito de cinco espa?amentos de plantio: T1 - 3,0 x 0,5 m; T2 - 3,0 x 1,0 m; T3 - 3,0 x 1,5 m; T4 - 3,0 x 2,0 m e T5 - 3,0 x 3,0 m. Realizou-se o invent?rio florestal cont?nuo nas idades de 48, 61, 73, 85 e 101 meses. Em cada ?rvore-amostra por unidade experimental na ?ltima idade foram: quantificada a biomassa; mensurada a ?rea e per?metro foliar, ?rea foliar espec?fica e realizada a an?lise qu?mica de N, P, K, Ca, Mg e S para amostras composta (ao longo do fuste) e simples (regi?o do DAP) dos componentes. Os resultados foram submetidos ? ANOVA, regress?o e a aplica??o das RNA. A modelagem por redes neurais artificiais demonstrou-se adequada para estimar a produ??o de biomassa de tronco em fun??o da idade sob diferentes espa?amentos, utilizando o DAP e per?metro foliar como vari?veis preditoras. N?o houve grande varia??o da efici?ncia de uso dos nutrientes entre os espa?amentos, principalmente para o tronco. A rede neural artificial foi eficiente em estimar a efici?ncia de uso dos nutrientes. A modelagem por redes neurais artificiais utilizando-se apenas amostra da casca na regi?o do DAP demonstrou ser adequada para a estimativa do coeficiente de utiliza??o biol?gico do tronco. / Disserta??o (Mestrado) ?

This work was divided into three chapters. The objectives were assess the coefficient of biological use (CUB's) of nutrients by eucalyptus trees, the efficiency and possible use of artificial neural networks (RNA) for the CUB's and biomass trunk under different spacings. The research plots was installed in december 2002 using a hybrid of Eucalyptus grandis W. Hill ex Maiden X Eucalyptus camaldulensis Dehnh. The statistical design was randomized blocks being studied, in three blocks, the effect of different planting spacings: T1???3,0?x?0,5?m, T2???3,0?x?1,0?m, T3???3,0?x?1,5?m, T4???3,0?x?2,0?m e T5???3,0?x?3,0?m. Data collection was carried out at ages 48, 61, 73, 85 and 101 months. In each sample-tree per experimental unit in the last age were: quantified biomass; measured leaf area, leaf perimeter, specific leaf area and chemical analysis of N, P, K, Ca, Mg and S for composite samples (along the stem) and simple samples (the region of the DAP) of components. Statistical analysis of the data consisted of ANOVA, regression and application of RNA. The modeling by artificial neural networks demonstred to be adequate to estimate the biomass of the trunk in relation to age at different spacings, using the DBH and perimeter leaf as predictors variables. There wasn't wide variation in efficiency use nutrient among spacings, especially for the trunk. The artificial neural network was effective in estimating the efficiency of nutrient use. The modeling by artificial neural networks using only sample in the DAP region proved to be adequate for estimating the coefficient of biological use of stem.

Guapuruvu Reserve (RG) in Itamarandiba; Minas Gerais, in order to contribute to the knowledge of the patterns of regional flora; (b) to verify how the rock outcrops have influence on the ecological patterns of shrubs and arboreal species of an area of rocky stricto sensu savanna in PEB and go through the existence of indicator species in a specific type of ambient related rocks; e (c) evaluate the correlations between the distribution and density of shrub and arboreal species with the environmental variables and realize based on this correlation, a stratification of the area and describe the floristic composition and the total community structure and for each ambient formed in the fragmentation of the area of savannah stricto sensu studied in PERP. Plots of 20???50?m?(1,000?m?) were located by systematic form, with seventeen plots in area 1 (PERP), ten in area 2 (PEB) and nineteen in area 3 (RG), totaling the sample areas with 1.7 ha, 1.0 ha and 1.9 ha, respectively. In these plots, recorded all living shrub and arboreal individuals that attended to the inclusion criteria, diameter at 0.3 m above soil (DAS) ? 5 cm. In the three areas were collected ten single samples of topsoil (0-20 cm of depth) in each plot, to obtain a randomly compound sample of 300cm3. In PEB were collected information on the cover of rocks in each plot. In PERP was realized the georeferencing and of the relief survey of the plots and anthropic and natural events were observed per plot and utilized to compose the environmental variables group with the soil and relief variables. There were registred in three areas of savannah stricto sensu 5.078 shrub and arboreal individuals, where 1.651 in PERP (971,18 ind.ha-1), 440 in PEB (440 ind.ha-1) e 2.987 in RG (1.72,11 ind.ha-1), totaling 118 species in 78 genera and 42 botanical families. The areas 1 and 2 are the most similar according to results Detrended Correspondence Analysis (DCA) and Principal Component Analysis (PCA). In the aggrouping analysis (dendogram) e DCA performed with ten plots of the PEB, show that these are divide into two groups of according with rock outcrops covering within some of these plots; according to the indicator species analysis (ISA) in the analyzed species, four had significative preference to ambient with non existence of rock outcrops and three with the ambient with rock outcrops. In PERP the Canonical Correspondence Analysi (CCA) presents five distinct ambient, with the greater influence of the correlation among the species distribution and the environmental variables: shallow soils, % of sand, pH and t. Each ambient showed a different group of species with higher VI, and the ambient 1 and 5 were the dissimilar ones by the Jaccard analysis (Sj).

Os experimentos foram realizados no Centro Integrado de Propaga??o de Esp?cies Florestais ? CIPEF do Departamento de Engenharia Florestal da UFVJM, em Diamantina, Minas Gerais, constituindo os tr?s cap?tulos apresentados seq?encialmente. No cap?tulo 1, sementes de sucupira - preta foram submetidas aos tratamentos pr?-germinativos Controle (sem quebra de dorm?ncia), Imers?o em H2SO4 puro por 5 minutos, Escarifica??o mec?nica com lixa N?80, e Pr?-embebi??o em ?gua por 48h seguida de imers?o em H2SO4 puro por 5 minutos, em dois substratos (Papel e Areia). Todos os tratamentos pr?-germinativos promoveram a germina??o da sucupira - preta nos dois substratos, sendo que a Imers?o em H2SO4 puro por 5 minutos e a escarifica??o mec?nica com lixa foram os que apresentaram maiores valores para as caracter?sticas avaliadas. No cap?tulo 2, os experimentos foram instalados em dois ambientes (Pleno Sol e Casa de Sombra), sendo avaliados os efeitos de dois tamanhos de tubetes (55 cm? e 180 cm?) e quatro substratos (70% de vermiculita + 30% de casca de arroz carbonizada; 70% de vermiculita + 30% de moinha de carv?o; 70% de vermiculita + 15% de casca de arroz carbonizada + 15% de fibra de coco; e 40% de vermiculita + 30% de casca de arroz carbonizada + 30% de fibra de coco), sobre o crescimento em altura e di?metro do coleto de mudas durante 270 dias. O maior crescimento em altura e di?metro do coleto foram observados, em geral, com a utiliza??o do substrato 70% de vermiculita + 15% de casca de arroz carbonizada + 15% de fibra de coco e do tubete de 180 cm?, nos dois ambientes. No cap?tulo 3, aos 270 dias ap?s a semeadura, foram avaliados os efeitos dos tamanhos de tubetes, substratos e ambientes, semelhantes ao cap?tulo anterior, sobre as caracter?sticas morfol?gicas de qualidade de mudas (altura, di?metro do coleto, peso de mat?ria seca da parte a?rea, peso da mat?ria seca da raiz, peso da mat?ria seca total, rela??o peso de mat?ria seca da parte a?rea/di?metro do coleto, rela??o de altura da parte a?rea / peso de mat?ria seca da parte a?rea, rela??o entre o peso de mat?ria seca da parte a?rea / peso de mat?ria seca das ra?zes e o ?ndice de qualidade de Dickson).

The experiments were performed at the Center for Integrated Forest Species Propagation - CIPEF at Department of Forest Engineering UFVJM in Diamantina, Minas Gerais, Brazil, constituting the three chapters that were presented sequentially. In chapter 1, black sucupira seeds were treated by pre-germination control (no dormancy), Immersion in pure H2SO4 for 5 minutes, mechanical scarification with sandpaper number. 80, and pre-soaking in water for 48h and after, immersion in pure H2SO4 for 5 minutes, two substrates (Paper and Sand). All pre-germinative treatments promoted germination of black sucupira on both substrates, and the immersion in pure H2SO4 for 5 minutes and mechanical scarification with sandpaper presented the highest values for the parameters evaluated. In Chapter 2, the experiments were conducted in two environments (full sunlight and 50% of shade), evaluated the effects of two sizes of tubes (55 cm? and 180 cm?) and four substrates (70% vermiculite + 30% rice hulls, 70% vermiculite + 30% chaff coal, 70% vermiculite + 15% carbonized rice hulls + 15% coconut fiber, and 40% vermiculite + 30% carbonized rice hulls + 30% coconut fiber), on growth in height and stem diameter of seedlings during 270 days. The greatest growth in height and stem diameter were observed, in general, using the substrate 70% vermiculite + 15% carbonized rice hulls + 15% coconut fiber and plastic tube of 180 cm ? in both environments. In chapter 3, at 270 days after sowing, we evaluated the effects of tube sizes, substrates and environments, were similar to the last chapter on the morphological parameters of quality of seedlings (height, stem diameter, dry weight of shoot , dry weight of root, total dry weight, ratio of dry weight of shoot / stem diameter, ratio of shoot height / dry weight of shoots, ratio of dry weight of shoot / dry weight of roots and the Dickson quality index), the substrate 70% vermiculite + 15% carbonized rice hulls + 15% fiber coconut and tubes of 180 cm ? were higher than in most characteristics, regardless of the environment studied.

A participa??o de Produtores Rurais (PR) tem se destacado nos ?ltimos anos e socializa uma atividade ent?o praticada predominantemente por grandes empresas florestais, fato este que suporta a escassez de trabalhos direcionados para produ??o em menor escala. Este estudo objetivou avaliar as pr?ticas de silvicultura empregadas pelos PR tendo como refer?ncia as pr?ticas adotadas por uma empresa que utiliza em seus plantios as melhores tecnologias silviculturais; estimar os custos de forma??o e condu??o de florestas conforme os procedimentos empregados pelos produtores em rela??o a diferentes op??es tecnol?gicas; e analisar o retorno de investimentos estimados sob crit?rios econ?micos. A popula??o abrangida neste estudo correspondeu a 583 PR do Alto Jequitinhonha que apresentaram Declara??es de Colheita e Comercializa??o no Instituto Estadual de Florestas entre janeiro de 2008 e outubro de 2009. Neste universo, 71 PR foram escolhidos aleatoriamente para responder um formul?rio com perguntas que abordaram a origem do material gen?tico, espa?amento, rota??o, todas as pr?ticas de silvicultura, a colheita e comercializa??o da madeira adotada. Estas mesmas vari?veis foram avaliadas em uma grande empresa florestal instalada na regi?o que trabalha com as melhores pr?ticas silviculturais. Ap?s obtidos, os dados foram analisados pela estat?stica descritiva. Os PR do Alto Jequitinhonha t?m significativa ?rea plantada com Eucalyptus urophylla e E. cloesiana, entretanto a tecnologia de silvicultura adotada ? obsoleta em rela??o ?s tecnologias empregadas por grandes empresas. Consequentemente, reduzem-se o potencial produtivo dos s?tios florestais e o retorno econ?mico. De forma geral a madeira de eucalipto ? direcionada para produ??o de carv?o vegetal. A tecnologia utilizada pelos produtores rurais na regi?o de estudo n?o ofereceu os melhores resultados econ?micos em qualquer dos cen?rios de pre?os estudados quando comparadas com a tecnologia utilizada pela empresa que utiliza elevado n?vel tecnol?gico. Devido ?s suas propriedades tecnol?gicas e ao uso pelo mercado madeireiro, a melhor viabilidade econ?mica para a madeira do E. cloesiana ? sua comercializa??o para a produ??o de postes de cerca, mour?es e para a constru??o civil. / Disserta??o (Mestrado) ?

The participation of farmers has been prominent in recent years, increasing the social benefits of eucalyptus plantation, as it had been traditionally planted by large forest companies so far. This study aimed to evaluate the forestry practices employed by these farmers in comparison to the best practices adopted by traditional companies, by estimating cost x benefit relation of forestry as a complementary business, based on the procedures carried out by these farmers under different technological options. The population covered by this study was represented by 583 farmers from Alto Jequitinhonha, who registered a document called ?Harvest statement?, as required by the state agency ?Instituto Estadual de Florestas?, between January 2008 and October 2009. From these, 71 farmers were randomly selected to answer a questionnaire addressing data such as the origin of species, spacing, rotation, the main silvicultural practices, harvesting and commercialization strategies employed. The same variables from a large regional forestry company were evaluated and used as reference. Data collected was analyzed by using descriptive statistics. It was found that farmers of Alto Jequitinhonha owns a very significant planted area with Eucalyptus urophylla and E. Cloesiana, although they employ much lower technological level in comparison to the technologies used by the large company. In consequence, the potential yield in these sites is reduced. In general, the eucalyptus wood is intended for charcoal production. The technology used by farmers in the study area did not offer the best economic results in any of the price scenarios studied, when compared to the company used as reference. E. cloesiana showed a better economic return, due to its technological properties and better acceptance into the local market, for lamp posts, fence posts and overall use in civil construction.

From 2007 to present date, it reached approximately 50,000 hectares in development projects with the protective bias. The techniques used in forest development projects are the promotion or induction of natural regeneration, the enrichment trough seedlings and when it is necessary, the plantation of the whole area with seedlings of native tree species from the region. To assess whether these restore\ recovery actions are reaching their goals, whether the resources invested in these actions are being well employed, or even if it will be necessary some rearrangement in the taken actions, it was necessary to evaluate and monitor the restored areas within the program scope. Before this effort, the monitoring of these worked areas allows that the development program assess the improvement rates in order to make them more effective. This study aims to suggest an assessment methodology of the restoration projects of the forest development program, guided by principles, criteria and indicators, seeking to verify the trends of successful projects. 19 projects were randomly visited in the municipalities of Concei??o do Mato Dentro, Datas, Diamantina, Rio Vermelho, Santo Antonio do Itamb? and Serro and it was applied an array of indicators based on two criteria therefore any civil servant in the local authority would be able to apply it, without needing an expertise to perform the monitoring. Based on technical and legislative recommendations, it was developed benchmarks to assess the project status executed. Because of the different phyto-physiognomies in studied area some benchmarks were developed for the Stational Semideciduous Forest and Rupestrian Field. Data were analyzed through principal component analysis (PCA) and TWINSPAN. With the proposed methodology it was possible to verify if the development projects were suitable with literary and technical recommendations. This study demonstrates that it is possible to perform the monitoring of recovering\ restoration projects of the forest development program of the IEF. Another important feature is guided by the usage of low financial resources and it also points the performance of evaluated projects. The proposal was not able to point all ecological benchmarks, but it detects favorable and unfavorable changes concerning the resilience of the recovery projects, requiring further studies and adjustments in order to add improvements to the quality of monitoring.

Foi instalado um experimento em ?reas da empresa APERAM BIOENERGIA, no munic?pio de Itamarandiba - MG, utilizando o delineamento experimental, blocos ao acaso. As parcelas foram constitu?das por cinco espa?amentos iniciais de plantio (3,0 x 0,5 m; 3,0 x 1,0 m; 3,0 x 1,5 m; 3,0 x 2,0 m e 3,0 x 3,0 m) e as ?pocas de medi??o ocorreram aos 7, 12, 18, 24, 48, 61, 77, 85 e 102 meses. A partir das informa??es coletadas em campo, foram estimados para cada tratamento o volume e a biomassa por hectare, a densidade b?sica, o poder calor?fico superior, al?m de outras vari?veis dendrom?tricas e de povoamento. Verificou-se que o espa?amento e a idade influenciaram significativamente nos valores de di?metro m?dio, de altura total, de ?rea basal por hectare, de volume total por hectare, de biomassa por hectare, de densidade b?sica da madeira e de poder calor?fico superior. O crescimento em volume por hectare em biomassa por hectare e em ?rea basal por hectare apresentou rela??o direta com a densidade de plantio, sendo os maiores valores obtidos nos menores espa?amentos. Por outro lado, o di?metro m?dio e a altura total das ?rvores apresentaram correla??o negativa com a densidade de plantio. A densidade b?sica tende a aumentar com o espa?amento e com a idade das ?rvores. E o poder calor?fico tende a elevar-se com a idade e com o espa?amento de plantio.

The experiment was performed in areas of the company APERAM BIOENERGIA in the city of Itamarandiba, MG, using a randomized block design. The plots consisted of five spacing initial (3.0 x 0.5 m, 3.0 x 1.0 m, 3.0 x 1.5 m, 3.0 and 3.0 x 2.0 x 3.0 m) and measurements were performed at 7, 12, 18, ??24, 48, 61, 77, 85 and 102 months. From the information collected in the field were estimated for each treatment the volume and biomass per hectare, density, calorific value, and other dendrometric variable and stand variables. It was found that the spacing and age influence significant on the values ??of average diameter, height total, basal area, volume total per hectare, biomass per hectare, density and calorific value. The growth in volume per hectare in the biomass per hectare and basal area per hectare was directly related to planting density, and the higher values ??for the smaller spacing. On the other hand the average diameter and total height of the trees were negatively correlated with the density. The specific gravity tends to increase with age and with the spacing of the trees. And the calorific value tends to rise with age and with the planting spacing. The spacing did not influence the survival rate of trees. The technique rotation and economic rotation occurred earlier in smaller plantings spaced. For all spacing the technique age cutting was higher than the economic age cutting. The spacing of 3.0 x 1.5 proved to be a more attractive option according to the criteria net present value and equivalent periodic benefit, considering the sale of standing timber.

The remnant has approximately 162 hectares and is located on the Experimental Moura?s Farm in Curvelo, MG, which were systematically allocated 25 plots of 400 m? (10 X 40 m), and all the individuals of the woody compartment who had bole with a DBH ? 5 cm were recorded values?? of DBHs, total height and bole, and categorical attributes related to the sanity and tortuosity of the boles. Were sampled 1105 individuals in 114 species, 41 families and 91 genera. The values? ?found for the index of Shannon Weaver diversity and evenness were 3.91 and 0.82 respectively. By volume analysis, it was found that models that use basal area and the average height as independent variables have rough estimates to quantify the stand volume, being indicated for this purpose. Similarly, the methodology of artificial neural networks also proved to be efficient in quantifying the volume of native forests in the conditions of this study, by the test and significance level adopted. The association of categorical variables to continuous in the input layers of neural networks generated, did not result in more accurate estimates by the conditions assumed in this work.

Pesquisa do estado de Minas Gerais (FAPEMIG) / Objetivou-se com esse trabalho avaliar o impacto do uso de herbicidas na regenera??o e no banco de sementes em ?reas em processo de recupera??o. Para isso, foram desenvolvidos quatro experimentos sendo tr?s em ambiente de campo e um em ambiente protegido. No primeiro experimento, avaliou-se a infesta??o de gram?neas ex?ticas sobre o processo de regenera??o natural. No segundo, avaliou-se a influ?ncia do banco de sementes no processo de restaura??o de ?reas infestadas com plantas daninhas gram?neas. No terceiro trabalho, foi avaliada a sensibilidade de algumas esp?cies arb?reas nativas ? a??o do herbicida glyphosate e no quarto e ?ltimo experimento foi avaliado o efeito desse herbicida e do paraquat no controle das gram?neas invasoras em ?reas degradadas, comparado ? ro?ada, visando ? adequa??o de m?todos mais eficientes no controle de plantas daninhas. A partir de uma cobertura de plantas daninhas acima de 50% h? retrocesso no processo de regenera??o natural, por?m, h? um grupo de plantas capaz de colonizar tal ?rea. Verificou-se tamb?m que o banco sementes ? composto basicamente por esp?cies herb?ceas com car?ter invasor, n?o contendo sementes de esp?cies arbustivo-arb?reas, logo, n?o ? recomendada a recupera??o dessas ?reas utilizando o banco de sementes local. No ensaio com doses do glyphosate, concluiu-se que tr?s das quatro esp?cies florestais avaliadas possuem caracter?sticas que indicam toler?ncia ao herbicida testado, por?m, recomenda-se a realiza??o de testes em campo em est?dios alternativos de desenvolvimento. Na compara??o de m?todos de controle das gram?neas, embora n?o observadas diferen?as entre os herbicidas aplicados, parcelas tratadas com glyphosate apresentaram emerg?ncia de esp?cies presentes no banco ed?fico ao passo que nas parcelas tratadas com paraquat somente foram observadas brota??es. De modo geral, pr?ticas no controle qu?mico das plantas daninhas gram?neas devem ser adotadas para que a ?rea atinja a plena restaura??o. Recomenda-se a inclus?o de outras t?cnicas de recupera??o para que haja a entrada de esp?cies arb?reas adaptadas ao local. / Disserta??o (Mestrado) ?
