Turismo e economia solidária : uma análise nas cooperativas e associações de artesanato do Roteiro Seridó norte-rio-grandense

The present study has addressed the issues surrounding the Solidarity Economy and Tourism, their perspectives and contributions to the development process of local communities, as well as the connection point between the two. This study evaluated the extent to which social economy through cooperatives and associations in tourism has generated socio-economic improvements for the artisans of the tourist Seridó. The study made as to their objectives, was exploratory and descriptive, since it involved both standard techniques of data collection, questionnaires and systematic observation, and secondary research and case studies, which characterizes an exploratory research, according to Castro (2008 ). The results indicate significant improvements offered by the inclusion of members in groups (associations and cooperatives) in matters concerning health, education, interpersonal relationships, and access to consumer credit to the artisans. Through this study, one might also note that the inclusion of products and services in tourism is not a relevant factor for the socio-economic improvements observed for the elevated presence of middlemen in the marketing process

Diagênese e proveniência dos arenitos da tectonossequência Rifte na bacias do Rio do Peixe Araripe, NE do Brasil

This thesis presents diagenetic and provenance studies of sandstones belonging to the Rift Tectonosequence of the Rio do Peixe and Araripe basins. These basins are located in the interior of Northeast Brazil aligned along the Trend-Cariri Potiguar. Their origin is related to the Early Cretaceous rifting event. In terms of lithostratigraphy, the studied section corresponds to the Antenor Navarro, Sousa and Rio Piranhas formations of the Rio do Peixe Basin, and the Missão Velha and Abaiara formations of the Araripe Basin, outcropping in the central-west Cariri Valley. A facies analysis was performed and identified nine distinct sedimentary facies for the Rio de Peixe Basin and ten sedimentary facies for the Araripe Basin, individualized according to the different rock types and their sedimentary structures. These facies associations to led paleoenvironments interpretations and their vertical succession allowed understanding the evolution of the depositional setting during the cronostratigraphic interval studied in these basins. Based on petrographic and diagenetic studies it was possible to characterize the texture and mineralogy of these sandstones, identifying their diagenetic stage and the grain framework provenance. The petrographic study allowed to classify the lithotypes studied in both basins as quartzarenites. Such quartzarenites, in general, are rich in quartz, feldspar and lithic fragment grains, and at accessory levels tourmaline, sphene, zircon, epidote and other mineralogy. The diagenetic history of the studied rocks proved to be very complex, being characterized by a variety mineral of phases that succeeded each other during the eo, meso and telodiagenetic stages. According to the studied formation and the textural and compositional aspects of the rocks, some processes were more or less active, while others were even absent. The eodiagenetic stage is marked by mechanical infiltration of clays and early mechanical compactional processes. The mesodiagenetic phase is characterized by continuity of the mechanical compaction and the beggining of chemical compaction, with quartz and feldspar overgrowths, precipitation of kaolinite, alteration of framework grains to chlorite and illite, and finally, precipitation of opaque minerals. The telodiagenetic stage is represented by the oxidation of some grains, matrix and cements. For the provenance analysis of the studied sandstones were used ternary diagrams whose vertices correspond to the percentage of quartz, feldspar and lithic fragments. This study allowed identifies the source area of these rocks as continental blocks. It was also possible, based on the chemical stability and mineralogical maturity of the rocks, recognize that the Antenor Navarro Formation of the Rio do Peixe Basin, and the upper section of the Missão Velha Formation of Araripe Basin have less maturity and stability when compared with the other studied formations

O Circuito espacial de produção do biodiesel: configuração no território brasileiro e uso do território Norte-Rio-Grandense

This research aims to understand the use of the territory from the Rio Grande do Norte to the circuit spatial of production from the Biodiesel understanding it as part of the national context. The introduction of biodiesel into the Brazilian energy matrix begins to take shape in the year 2005 with the implementation of the National Program for Production and Use of Biodiesel (NPPB). This is anchored on three pillars: social inclusion (through family agriculture), environmental sustainability and economic viability. The NPPB consists of a set of standards, which turned into shares and distributed by almost all the national territory. Our reflection assumes that the places accommodating different forms of productive activities and, thus, the performance of the circuit space of biodiesel production depends on several factors, including the configuration of the territory they receive this new nexus economic. Understanding that the places by their technical content determine the realization of productive activities, it was found that the inclusion of this circuit space production in Rio Grande do Norte, reveals the reality expressed in the national territory, where some places are endowed with a privileged technical content and other extremely poor infrastructure. As our research could confirm the circuit space of biodiesel production that is expressed in the way plants are distributed within the country (mostly in South-Central), in more significant participation of small farmers in the South in the supply of raw material for the production of biodiesel and the main raw material used for the production of agrofuels (soybeans, whose production sector is highly consolidated and technified). Already the project materialization of NPPB regarding the settlements and communities of the Rio Grande do Norte State, we observed that the "event" or advent of realization encountered a technical means lacking in infrastructure that need to be molded to the needs of production, or is to cultivate castor beans or sunflower would be needed inputs and implements that farmers don´t have. Given the above, the research concludes that, as proposed previously, the use of the territory of Rio Grande do Norte to this circuit has summarized the performance of experiments, either with regard to the participation of family farmers as suppliers of raw materials, including the development of related research in the stage of production fuel oil by Petrobras. This finding came from research done from the concept of "spatial circuits of production," which allowed the verification of the circuit that steps outlined in Potiguar territory. Regarding the inclusion of family farmers in the productive circuit in RN, research reveals that, in the manner as has been done, it is doomed to failure. Furthermore, we dare say that this persistence in trying to put these family farmers, the way is being made, and the resulting successive failures, indicating that social inclusion advocated by NPPB not take place, and that this production circuit relies on the same logic circuit concentrated and exclusive space for ethanol production

Identificação da dinâmica espaço-temporal para estimar área cultivada de soja a partir de imagens MODIS no Rio Grande do Sul

The objective of this study was to define a method for estimating soybean crop area in the Northern Rio Grande do Sul state (Brazil). Overall, six different remote sensing methods were proposed based on spectral-temporal profile and minimum and maximum values of NDVI/MODIS related to the stages of sowing, maximum development and harvesting of soybean areas. The resulting estimates were compared to official crop area data provided by the Brazilian government, using statistical analysis and the fuzzy similarity method. The performance of each method depended on information such as crop size, type of crop management, and sowing/harvesting dates. Regression coefficients of determination and fuzzy agreement values were above 0.8 and 0.45, respectively, for all methods. For operational monitoring of soybean crop area, the empirical threshold applied to the image difference with inclusion of harvest image method was the most effective, producing estimates that matched closely the official data. For spatial analysis the application of multitemporal images classification method is recommended that generated a map of better quality. The efficiency of these methods should be evaluated in the areas of soybean expansion in the state.

Zaira de Bittencourt Martins: pioneira da psicanálise de crianças no Rio Grande do Sul

The objective of the present article is to introduce Zaira de Bittencourt Martins’s contributions to psychoanalysis in Rio Grande do Sul, identifying her as pioneer in child psychoanalysis in this State. Starting from a historic research based on interviews with psychoanalysts, bibliographical sources and contacts with relatives, the author composed a biographical outline of the psychoanalyst above mentioned. Zaira Martins, together with her husband, the psychiatrist and psychoanalyst Mario Martins, immigrated to Argentina in 1944, and in 1947 was recognized as an analyst by the Argentinian Psychoanalytic Association. On her return to Brazil she became the first non physician woman to make part of the Psychoanalytic Society of Porto Alegre, collaborating with her foundation, in 1963. She played the pioneer role as child psychoanalyst and contributed in the dissemination of Kleinian ideas in her State. She also contributed in the formation of young analysts who were beginners in the child analyst field, through courses and supervisions.

Stable carbon and oxygen isotope ratios of Miocene to Recent foraminifera from the Rio Grande Rise, South Atlantic

Miocene to Recent species of planktic foraminifera in the Globorotalia (Globoconella) lineage evolved entirely within the thermocline. All species are most abundant within subtropical-temperate watermasses throughout their history. The near stasis in distribution within the thermocline and the subtropical convergence suggests the major morphological changes in Globorotalia (Globoconella) may have occurred through habitat subdivision rather than by vicariant shifts into new watermasses. At the Rio Grande Rise, in the South Atlantic, modern G. inflata is 0.66-0.84? more positive for delta18O than the most enriched coexisting Globigerinoides sacculifer and probably grows in the mid thermocline deeper than 325 m. All extinct globoconellid species have mean delta18O ratios 0.5-0.8? more positive than Globigerinoides trilobus and G. sacculifer and probably lived within the thermocline as well. Major events in skeletal evolution are poorly correlated with changes in delta18O in this group. These include evolutionary transitions to compressed, smooth-walled tests and acquisition of keels. In addition, morphological reversals from the umbilically-inflated G. conomiozea to biconvex G. pliozea and to unkeeled G. puncticulata occur in the absence of changes in delta18O signature. Instead, the ranges of delta18O between different species almost completely overlap once corrected for temporal changes in delta18O of sea water. Foraminifera morphologies have been widely considered to evolve in response to changes in watermasses or depth habitats. However, the variety of skeletal shapes in the globoconellid lineage apparently are not adaptations to a progressive radiation from the surface mixed layer into deeper waters.

Promotion of intangible heritage as a tool to strengthen revitalisation of historic centres: the case of de Monumenta Programme in the City of Porto Alegre (Rio Grande do Sul State) Brazil

The preservation of tangible cultural heritage does not guarantee effective revitalisation of urban historic areas as a whole. The legacy of our history consists not only of paintings, sculptures, architectural monuments and public spaces, but also the safeguarding of immaterial aspects of social life, such as oral traditions, rituals, practices, knowledge and craft skills. From 1999 to 2013, 26 Brazilian cities benefited from the Monumenta Programme - a national cultural policy that involved institutions, the private sector and the local community. The purpose of the programme was to stimulate economic growth and increase cultural and social development of the historic centres. Moreover, it sought to increase the number of residents in the benefited areas as defined in its agenda (IDB, 1999; MinC & Programa Monumenta, 2006). Using the Historic Centre of Porto Alegre as a case study, this paper examines how this cultural programme enables demographic change through the promotion of intangible cultural heritage, e.g. by supporting educational projects. The demographic flow was analysed using the microdata of the Populations Censuses (years 2000 and 2010) available from the Brazilian Institute of Geography and Statistics. The results showed an increase in low-income residents the areas that participated in the programme. This increase may have been motivated by a set of cultural-educational projects under the auspices of the Monumenta Programme. The retraining of artisans of Alfândega Square, the training of low-income youth for restoration work and the implementation of the "Black Route Museum in Porto Alegre" (Bicca, 2010) are just some examples of what was done to improve the local community's economy, to encourage social cohesion and to enhance the awareness of cultural diversity as a positive and essential value in society.

Evaluación del impacto del programa Monumenta en los centros históricos del sur de Brasil : los casos de Pelotas, Porto Alegre (Rio Grande do Sul) y São Francisco do Sul (Santa Catarina)

Esta Tesis tiene como objetivo demostrar que los programas de preservación del patrimonio, durante su fase de implementación, deben someterse a un análisis multidisciplinar que haga un balance de su ejecución. Dicho análisis permitirá identificar resultados significativos, capaces de fundamentar la rectificación de las bases conceptuales de la política pública en cuestión. Este reajuste podrá darse, por lo tanto, durante su vigencia y, de forma más relevante, posteriormente, sus motivos y resultados permitirán elaborar nuevas estrategias que serán aplicadas en futuros programas de intervención. Por otro lado se indagó, además, si las ciudades participantes en un programa nacional de preservación del patrimonio, regidas por normas y metas comunes, podrían alcanzar resultados diferentes. Para atender a estos objetivos, la investigación se encuentra enfocada a la realidad brasileña, siendo seleccionado como objeto de estudio el Programa Monumenta. Este Programa formó parte de la política pública cultural del Ministerio de Cultura con una importante implicación del Banco Interamericano de Desarrollo. Implementado a partir de 1999, procuró promover un proceso de recuperación urbana sostenible y de preservación del patrimonio de 26 Sitios Históricos Urbanos o Conjuntos de Monumentos Urbanos protegidos por el Instituto del Patrimonio Histórico y Artístico Nacional (Iphan). El Programa contó con el apoyo de la Unesco y del Iphan, así como con la participación de las Administraciones Municipales y/o Estatales, sectores privados y la sociedad civil. Las hipótesis planteadas en esta Tesis Doctoral fueron: (a) el análisis de los resultados en la fase de implementación de un programa de preservación del patrimonio es imprescindible, porque permite extraer conclusiones preliminares y orientar sus reformas; (b) los objetivos a corto plazo establecidos por el Programa Monumenta fueron alcanzados de modo diferenciado en las distintas ciudades beneficiadas; (c) a pesar de las diferencias, el Programa Monumenta presentó resultados preliminares positivos y significativos en la preservación del patrimonio histórico urbano brasileño. Los procedimientos metodológicos se centraron en un análisis cuantitativo, cualitativo y comparativo de los resultados alcanzados por tres ciudades beneficiadas por el Programa Monumenta, seleccionadas según su tamaño poblacional: Pelotas, Porto Alegre (Estado de Rio Grande do Sul) y São Francisco do Sul (Estado de Santa Catarina). Estos procedimientos fueron aplicados en los siguientes indicadores: utilización de los equipamientos culturales, características de la población y de los domicilios, variación de las actividades económicas, financiación destinada al sector privado para la recuperación de inmuebles y el fomento de la seguridad urbana. La Tesis ha englobado discusiones y conceptos abordados en las disciplinas de la Sociología Urbana, Geografía Urbana, Historia, Economía y Estadística de modo que se atribuye al objeto de investigación una visión interdisciplinar que ayudará a la comprensión de la teoría y la práctica preservacionistas. El análisis de la varianza, la regresión lineal y el análisis factorial fueron las herramientas estadísticas aplicadas sobre los datos con el objetivo de constatar la significación de los resultados y la relación de correspondencia entre algunas variables. Esta Tesis contribuye a la elaboración de una metodología analítica que puede ser aplicada en el cálculo de la superficie ocupada por las actividades económicas, con base en el método estadístico del Diagrama de Caja y Bigotes, de John Wilder Tukey. Las conclusiones corroboran las hipótesis planteadas y pretenden contribuir al diseño de las nuevas políticas públicas de preservación de sitios históricos de carácter urbano, enfatizando, con ello, la necesidad de evaluaciones más profundas de los resultados durante su fase de implementación. ---------------------------------------------------------------------------------- RESUMO--------------------------------------------------------------------------- A presente Tese apresenta como objetivo principal demonstrar que os programas de preservação do patrimônio histórico, durante a sua fase de implementação, necessitam de uma análise multidisciplinar sobre a sua execução. Essa análise permite identificar resultados significativos, capazes de fundamentar a retificação das bases conceituais da política pública em questão. A correção poderá, portanto, ser realizada tanto durante a sua vigência como posteriormente, ao permitir a elaboração de novas estratégias a serem aplicadas nos futuros programas de intervenção. Por outro lado, indagou-se se cidades participantes de um mesmo programa nacional de preservação do patrimônio histórico, regidas por normas e metas comuns, poderiam alcançar resultados não similares. Para atender tais objetivos, a investigação enfoca a realidade brasileira, tendo sido selecionado o Programa Monumenta como objeto de estudo. Esse Programa fez parte de uma política pública cultural do Ministério da Cultura, que atuou em parceria com o Banco Interamericano de Desenvolvimento. Implantado em nível nacional, a partir de 1999, visava promover um processo de recuperação urbana sustentável, bem como a preservação do patrimônio de 26 Sítios Urbanos Históricos ou Conjuntos de Monumentos Urbanos, protegidos pelo Instituto do Patrimônio Histórico e Artístico Nacional (Iphan). O Programa contou com o apoio da Unesco e do Iphan, além da participação das Administrações Municipais e/ou Estaduais, setores privados e sociedade civil. As hipóteses estabelecidas nesta Tese Doutoral foram: (a) a análise dos resultados na fase de implementação de um programa de preservação do patrimônio é imprescindível, pois permite extrair conclusões preliminares e orientar as suas reformulações; (b) os objetivos em curto prazo, estabelecidos pelo Programa Monumenta, foram alcançados de modo diferente pelas cidades beneficiadas; (c) apesar das diferenças, o Programa Monumenta apresentou resultados preliminares positivos e significativos sobre a preservação do patrimônio histórico urbano brasileiro. Os procedimentos metodológicos se centraram em análises quantitativa, qualitativa e comparativa dos resultados alcançados em três cidades beneficiadas pelo Programa Monumenta, selecionadas de acordo com o tamanho populacional: Pelotas, Porto Alegre (Estado do Rio Grande do Sul) e São Francisco do Sul (Estado de Santa Catarina). Esses procedimentos foram aplicados nos seguintes indicadores: utilização dos equipamentos culturais, características da população e dos domicílios, atividades econômicas, financiamento destinado ao setor privado para a recuperação dos imóveis e, ainda, o fomento da segurança urbana. A Tese inclui discussões e conceitos abordados nas disciplinas de Sociologia Urbana, Geografia Urbana, História, Economia e Estatística, de modo a atribuir ao objeto de investigação uma visão interdisciplinar e uma compreensão entre a teoria e a prática preservacionista. A análise de variância, regressão linear e análise fatorial foram as técnicas estatísticas aplicadas sobre os dados, com o objetivo de constatar a significação dos resultados e a relação de correspondência entre algumas variáveis. Esta Tese contribui com a elaboração de uma metodologia aplicada no cálculo da superfície ocupada pelas atividades econômicas, utilizando como método estatístico o Diagrama de Caixa e Bigodes, de John Wilder Tukey. As conclusões corroboram com as hipóteses estabelecidas e pretendem contribuir para o desenho de novas políticas públicas de preservação de sítios históricos de caráter urbano, enfatizando a necessidade de avaliações mais profundas dos resultados durante a sua fase de implementação. ---------------------------------------------------------------------------------- ABSTRACT ---------------------------------------------------------------------------------- The main goal of this PhD. Thesis is to demonstrate that a multidisciplinary analysis is needed during the implementation phase of preservation of heritage programmes. Such analysis allows the identification of significant results, which in turn can serve as the foundation for the conceptual bases of the public policy at hand. Thus, any corrections can be made both during the programme and afterward, by introducing new strategies to be applied in future intervention programmes. On the other hand, this project also asks whether cities participating in the same national preservation of heritage programme with common rules and goals can achieve distinct results. In order to meet these objectives, the project chose Brazil as its focus and Monumenta Programme for its object of study. This Programme is part of the Ministry of Culture’s public cultural policy, and was developed with cooperation by the Inter-American Development Bank. Implemented at the national level in 1999, the Programme aimed at promoting a process of sustainable urban renewal and the preservation of 26 urban historic sites or urban monumental ensembles, protected by the National Historic and Artistic Heritage Institute (IPHAN). UNESCO and IPHAN supported the Programme, and participants included municipal and state offices, private businesses, and local residents. The hypotheses established in this Doctoral Thesis were: (a) the analysis of the results in the implementation phase of a cultural public policy is imperative, because it enables preliminary conclusions to be drawn and orientate reforms; (b) the short-term objectives set out in the Monumenta Programme were achieved differently in the benefitted cities; (c) despite the differences, the Monumenta Programme displayed significant positive preliminary results in the conservation of the urban historic heritage in Brazil. Methodology procedures centered around quantitative, qualitative, and comparative analyses of the results achieved in three benefiting cities, selected according to population size: Pelotas, Porto Alegre (Rio Grande do Sul State) and São Francisco do Sul (Santa Catarina State). These procedures were applied to the following indicators: the use of the cultural facilities, characteristics of the population and the residential housing, variation of the economic activities, financing destined for the recovery of real estate, and promoting urban safety. The Thesis includes discussions and concepts addressed in urban sociology, urban geography, history, economics, and statistics, in order to examine the object of study with an interdisciplinary eye and an understanding between preservation theory and practice. Variance analysis, linear regression, and factorial analysis were the statistical techniques applied to the data, with the goal of defining the significance of the results and the correspondence ratio between some of the variables. This Thesis attempted to elaborate an applied methodology for calculating the space occupied by economic activities, using John Wilder Tukey's statistical method of Box-and-Whisker Plot. The conclusions corroborated the hypotheses established and are meant to contribute to the design of new public policies of historical site preservation in urban settings, emphasizing the need for deeper evaluations of the results during the implementation phase.

Contribuição a estratigrafia do Grupo Passa Dois no Rio Grande do Sul

O presente trabalho tem por finalidade estudar as relações estratigráficas das rochas consideradas do Grupo Passa Dois no Estado do Rio Grande do Sul. Este estudo foi feito através de levantamento de secções geológicas perpendiculares ao mergulho das camadas, em regiões cujo reconhecimento preliminar determinou serem as mais propícias para a demonstração das variações faciológicas das unidades. Foi completado com o estudo de testemunhos e perfis de sondagens e estabelecimento de secções colunares em áreas consideradas interessantes e que não se prestavam para um perfil contínuo. Foram feitas cinco seções, estudadas três áreas complementares e sete sondagens, cedidas pela Companhia Riograndense de Mineração - CRM. Os trabalhos de campo foram completados com estudos de laboratório que incluíram análises granulométricas, lâminas delgadas, testes colorimétricos e difração de Raios X. A integração dos dados de campo e de laboratório mostrou que: 1 - O grupo Passa Dois está constituído pelas Formações Irati e Estrada Nova, estando ausente a Formação Rio do Rasto, na faixa aflorante no Estado; 2 - A espessura do Grupo Passa Dois, na faixa aflorante no Estado varia ao redor de 100 metros; 3 - A Formação Irati apresenta duas fácies litológicas no Rio Grande do Sul. A primeira, quando presente, ocupa a posição basal e é caracterizada pela ocorrência de duas camadas de folhelhos pretos pirobetuminosos, associados com lentes calcárias fossilíferas. As camadas de folhelhos pretos contêm, entre elas, um pacote de folhelhos cinza com fratura concóide, com concreções calcárias de coloração amarelo-palha. Estas três camadas estão sobrepostas a um folhelho semelhante ao que está intercalado aos folhelhos pretos e contêm as mesmas lentes calcárias. A essa fácies é aqui proposta a designação fácies Tiaraju, indicando como área tipo a região a sul e a leste da estação Tiaraju, no município de São Gabriel. A segunda fácies, parcialmente sincrônica com a primeira, e que encerra a sedimentação Irati no Estado, é atípica da Formação Irati do resto da Bacia e pode ser descrita como folhelhos cinza-claros e cinza-escuros, às vezes com ritmitos na base, com laminação cruzada, com lentes calcárias de cor amarelo-palha. Em algumas áreas, como a Mina do Leão, os folhetos estão intercalados com siltitos e arenitos finos, de cor cinza, micáceos. A parte superior, a oeste de Pântano Grande, é cortada por veios verticalizados, espessura de 2 a 15 cm, preenchidos por sílica. Para esta fácies é proposta a designação fácies Valente e indicada como área-tipo a região a 5 quilômetros a norte do Passo do Valente, na estrada Bagé-Aceguá; 4 - O conteúdo fossilífero destas fácies da Formação Irati, no Rio Grande do Sul, é o mesmo; 5 - A Formação Estrada Nova também se apresenta com duas fácies litológicas bem distintas, sendo uma pelítica e outra arenosa. Em todas as regiões em que ambas ocorrem a arenosa situa-se no topo; 6 - O contato inferior da Formação Estrada Nova, com a Formação Irati, é marcado pelo aparecimento das cores vermelhas de alteração, que se intercalam com cores cinza-esverdeadas nos folhelhos e folhelhos sílticos. É considerado como topo da fácies inferior o aparecimento de arenitos muito finos em camadas lenticulares de pequena espessura que se alternam com lamitos vermelhos. Para a litofácies é aqui proposto o termo fácies Caveiras, sendo indicada como área tipo a região do Cerro das Caveiras no Município de Dom Pedrito; 7 - O contato superior da Formação Estrada Nova é com a Formação Rosário do Sul, sendo caracterizado pela ocorrência de arenitos médios, de coloração rosa, com estratificação cruzada planar ou acanalada, com conglomerados intraformacionais, ou de arenitos com estratificação ondulada. Este contato é, na maioria dos casos, erosivo sobre os sedimentos da Formação Estrada Nova, sendo aqui interpretado como discordante; 8 - O membro superior é caracterizado pela incidência de corpos lenticulares de arenitos muito finos e pela ocorrência de lentes calcárias com bordos irregulares, e de concreções calcárias elipsoidais de diâmetros de mais de dois metros. A este conjunto é aqui proposto o termo fácies Armada, sendo indicada como área tipo a região a leste do Rio Ibicuí da Armada, na estrada BR-293, no Município de Dom Pedrito; 9 - O conteúdo fossilífero da Formação Estrada Nova no Rio Grande do Sul, presentemente conhecido, não permite caracterizar qualquer das duas fácies.

Prevalência da síndrome metabólica e seus componentes nos estágios pubertários de escolares do sexo feminino norte-rio-grandenses

The diagnosis of nutritional status is extremely re levant in clinical practice and population assessment, due to the association betwe en body fat and metabolic alterations. The aim of this study is to analyze th e prevalence of metabolic syndrome (MS) and its components in the pubertal stages of f emale students in Rio Grande do Norte state, Brazil, in accordance with Internation al Diabetes Federation criteria. This is a cross-sectional study with 449 students aged betw een 8 and 19 years, stratified into pubertal stages systematized by Marshal and Tanner (1969), as follows: 27.6% prepubertal, 44.3% pubertal and 28.1% postpubertal, with mean ages of 9.4±1.27, 12.4±2.23 and 15.1±1.88 years, respectively. Preval ences were analyzed using distribution of frequencies and their respective 95 % confidence intervals, while the chi- square test and odds ratio were applied to analyze the associations between variables. The general prevalence of MS was 3.3% (CI: 2% - 5%) , without occurrences in the prepubertal stage, observing that it emerges from t he pubertal stage onwards with a prevalence of 2.5% (CI 95% 0.1% - 5%), 1% (CI 95% 0.4% - 2.3%) of cases with overweight and 1.5% (CI 95% -0.1% - 3.2%) with obes e individuals, while in the postpubertal stage the prevalence is 7.9% (CI 95% 3 .2% - 12.6%), 0.8% (CI 95% -0.8% - 2.3%) normal weight cases, 4% (CI 95% 0.6% - 7.4% ) overweight and 3.1% (CI 0.1% - 6.2%) obese individuals. There was an association (p<0.02) between pubertal stages and MS ( x 2 =5.2), with an OR of 3.3 (CI: 1.2 - 5), showing tha t postpubertal adolescents are more prone to SM than pubertals, while the OR i n obese individuals was 2.1 (CI: 2– 2.2) compared to the overweight. Body mass index (B MI) ( x 2 = 29.4; p<0.001) and age range ( x 2 = 13.1; p<0.001) showed a significant linear assoc iation with MS. Of the adolescents with MS, those aged ten years or younge r exhibited higher %G. The most prevalent components in all the stages were altered waist circumference (27.2% [CI 23% - 31%]) and low HDL cholesterol (39.6% [CI 35% – 44%]), which, coupled with hypertension, displayed significant differences in the postpubertal stage in relation to the other stages. The results show that MS emerges from the pubertal stage onwards in proportion to excess childhood body fat, a fact tha t calls for prevention strategies using an educational approach, reducing the large demand on the National Health System. Keywords: Metabolic syndrome, pubertal stages, risk factors.

Dinâmicas de reprodução do comércio e os novos papéis urbanos de pequenas cidades norte-rio-grandenses: um olhar a partir das redes associativistas de supermercados

The work presented here aims to make an analysis of the socio-spatial dynamics of associative supermarket chains and their importance in redefining the roles of small urban North Rio Grande cities. The theoretical approach gives priority to business as a city constituent whose understanding allows us to seize the new socio-spatial dynamics of small towns in the face of globalization and which caused changes in the scope of its commercial forms. In this sense, we understand that trade, as an essentially urban activity has a very specific characteristic, with respect to its ability to transform the content and meaning of places. Another important factor in the construction work was the context of changes in the capitalist production system with the advent of flexible production and the determinations of the economic globalization process that brought new ways of organizing trade. The empirical analysis of the research includes two associative supermarket chains, the “Rede 10” and the “Rede Seridó”, bringing together basic elements for understanding the genesis and evolution of this new organizational model of trade in small towns of the state, as well as allowed -In understand the main changes in this segment of commercial activity. The methodology we used literature in books and periodicals, collected mainly secondary data collection with the SEBRAE and the ABRAS and was still a field research where interviews were conducted forwarded along to the associative network managers to supermarkets, owners of associated facilities and with consumers of the surveyed networks .Finally, we conclude that the formation and expansion of associative supermarket chains in the context of small cities potiguares is essentially in a survival alternative traditional small traders, that sharing the associative principles albeit somewhat rigidly guided by the training cooperation networks can not only stay in the market , but to impose as a new agent in the capital of the reproduction process. Thus, the associative supermarket chains in the search for new spaces, particularly within small towns end up promoting new momentum in these cities providing different flows and interconnections with different places, giving new content and urban roles. By taking not only the condition of the place of living, but also the place to reproduce the capital, small towns offer their population better able to make purchases, thus avoiding the mandatory population shifts to other urban centers in order to meet their consumption needs.

Consanguinidade e efeito fundador da mutação G377S da doença de Gaucher em população de Tabuleiro do Norte – Ceará – Brasil

Gaucher’s disease (GD) is caused by a β-glucocerebrosidase deficiency, leading to the accumulation of glucocerebroside in the reticuloendothelial system. The prevalence of GD in Tabuleiro do Norte (TN) (1:4000) is the highest in Brazil. The purpose of this study was to present evidence of consanguinity and founder effect for the G377S mutation (c.1246G>A) among GD patients in TN based on enzyme, molecular and genealogical studies. Between March 2009 and December 2010, 131 subjects at risk for GD (GC in dried blood ≤2.19 nmol/h/ml) and 5 confirmed GD patients from the same community were submitted for molecular analysis to characterize the genetic profile of the population. Based on the enzymatic and molecular analysis, the subjects were classified into three categories: affected (n=5), carrier (n=20) and non-carrier (n=111). All carriers were (G377S/wt). Affected subjects were homozygous (G377S/G377S). The identification of a single mutation in carriers and homozygotes from different generations, the history of the community and the genealogy study suggest that the high prevalence of GD in this population may be due to a combination of consanguinity and founder effect for the G377S mutation

Foraminíferos, ostracodes e microfauna associada da plataforma continental equatorial norte-rio-grandense, NE Brasil: área Porto do Mangue a Galinhos

This study was conducted in the adjacent Brazilian equatorial inner shelf to Rio Grande do Norte, between the region of Porto do Mangue and Galinhos. The main objective is the characterization of biogenic sediments, especially foraminifera and ostracod collected on the surface of the seafloor. The methodology involved standard procedures including literature, surveys, processing of samples in the laboratory and identification of foraminifera and ostracods by genera or species under stereo microscopy and scanning electron microscopy (SEM). Multivariate statistical analyzes and study of ecological indexes were also applied to the study of foraminifera. Three transects, from inner shelf to slope were sampled: profile 01 (east, near Galos), profile 02 (center, near the city of Macau) and profile 03 (west, near Ponta do Mel). Results indicated the predominance of benthic foraminifera and little plankton occurrence. Benthic foraminifera genera observed in abundance were Quinqueloculina, Textularia, Globigerina and Pyrgo, Quinqueloculina, Textularia, Pyrgo, Ammonia, Elphidium, Pseudononion, Peneroplis, Bolivina and Poroeponides, occurred more frequently. Less frequently been described Amphistegina, Archaias, Bigenerina, Cibicides, Cassidulina, Amphicorina, Cornuspira, Paterina, Hopkunsina, Oolina, Uvigerina, Fusenkoina, Nonionella, Amphisorus, Wiesrella, Reussella, Reophax, Nodosaria, Marginulina and Cyclogyra. Six genera of ostracods were also identified: Puriana variabilis / P. convoluted?, Loxoconcha sp, Bairdiidae, Xestoleberis sp, Hemicytheridae and Ruggiericythere sp. Groups of organisms found in the studied shelf presented chemical composition of Ca, C, O, Na, Cl, Al, Mg, and Si. The proportions of chemical elements may vary according to the type of biogenic sediment, with the highest values identified as Ca, C, Cl, Na and O. The absolute dating by carbon 14 method indicated sediments of different colors (light and dark), correspond to a single age from 3000 to 6000 years BP, related to the Quaternary. These data intend to complement information about biogenic sediments in the Brazilian continental shelf, especially in the Northeast, where there is a lack of such studies.

Foraminíferos, ostracodes e microfauna associada da plataforma continental equatorial norte-rio-grandense, NE Brasil: área Porto do Mangue a Galinhos

This study was conducted in the adjacent Brazilian equatorial inner shelf to Rio Grande do Norte, between the region of Porto do Mangue and Galinhos. The main objective is the characterization of biogenic sediments, especially foraminifera and ostracod collected on the surface of the seafloor. The methodology involved standard procedures including literature, surveys, processing of samples in the laboratory and identification of foraminifera and ostracods by genera or species under stereo microscopy and scanning electron microscopy (SEM). Multivariate statistical analyzes and study of ecological indexes were also applied to the study of foraminifera. Three transects, from inner shelf to slope were sampled: profile 01 (east, near Galos), profile 02 (center, near the city of Macau) and profile 03 (west, near Ponta do Mel). Results indicated the predominance of benthic foraminifera and little plankton occurrence. Benthic foraminifera genera observed in abundance were Quinqueloculina, Textularia, Globigerina and Pyrgo, Quinqueloculina, Textularia, Pyrgo, Ammonia, Elphidium, Pseudononion, Peneroplis, Bolivina and Poroeponides, occurred more frequently.
