Entre o mar e estrela, um lugar para se bem viver : a problemática da expansão urbana da Cidade de Baía Formosa/RN

The urban expansion problem of Baía Formosa, a southern edge city of de Rio Grande do Norte eastern coast, which has been presented in other coast Brazilian towns, specially on those with tourist activities increase. Therefore, this situation brings huge concerns to their inhabitants, to their technical /scientific community and to the governments, because of the conflicts of interest and of the growth of urban problems that this has been created. At Baía Formosa, the situation is aggravated because the city is confined, once around it, there are large private proprieties, environmental preservation area and the sea, at the eastern edge. The objectives of this study are the analyses of this city expansion process in order to obtain adequate alternatives and defining methodology to apply in other urban nucleus that are subjected to similar situations. Of course, presents social relations, environmental conditions and promoting local population insertion should be considered in order that enjoin this process and contributing to a better social balance. This case study has used bibliography research, field data, maps and soil occupation recorders and photographs of the area, besides the primary data gathering by surveys carried out with many social actors. The present analysis shows that the urban expansion observed today is featured by a recent unsustainable model, which attacks the environment and brings either farm conflicts. On the other hand, the ecological tourism can represent an alternative in order to achieve an adequate expansion form, without forgetting the several structural parameters necessary to support the sustainable activities

Agroindústria canavieira e unidade de conservação: Impactos Sociais na comunidade de pescadores de Baía Formosa (RN)

The conservation unities emerged in response to the environmental damages. In the Atlantic Forest of the Brazilian Northeast, the most of the damages come from the sugar-cane agro-industry, especially by the deforestation for the introduction of sugar-cane fields and installation of the industry structure. Besides the damages over the biodiversity, there are critical social problems that affect the communities which survive using directly or indirectly the biome from the Atlantic Forest. The objective of this research is to analyze the social impacts on the fishermen of Baía Formosa/RN generated by the changes and socio-environmental transformations occurred starting the installation of a sugar-cane factory and the creation of a conservation area in the municipality of Baía Formosa/RN community. The research is based on a qualitative and diachronic perspective, for both approach, it was used the method of oral history in conjunction with the literature search and some technical and research tools such as direct observation, interview, records images and recordings . The results show that social and symbolic practices of the community in the conservation unit Mata Estrela last more strongly presented. Today fewer natural resources are used, due to factors such as limit access to forest and disappearance of some natural resources by deforestation. It is believed that the loss of free access to space for the community is the most significant negative impact, as promoted changes in the relationship of the community with the Star Forest that contributed to the fading of their social and symbolic practices. The loss of free access caused the decline in the practice of agriculture, which resulted in the loss of one of the means of social reproduction of the community

Análise de estabilidade de falésias na zona costeira de Baía Formosa - RN

The natural and anthropogenic changes that are occurring at the coastal zone around the world represent the greatest problem to society in this century. This problem becomes more evident due to high density of coastal cities, to growing tourist-estate speculation of those areas and to climate change that tend to trigger and accelerate the erosive processes that operating in the littoral. In this context, it‟s possible perceive ever more a significant increase of problems associated to the coastal erosion and retreat of cliffs in the state of Rio Grande do Norte, where this study area of this search is located. The area is located in the coastal zone of the city of Baía Formosa/RN, in south-eastern coast of Rio Grande do Norte, and has a extension of about 1200 meters along the Porto beach. The main objective of this study is to analyze the stability of these cliffs in this region. Through field investigations, testings and computational analysis using the Finite Element Method and Equilibrium Limit Methods. The area was divided into four sections, and were applied checklists, and also realized characterization tests and direct shear tests with materials obtained along these sections. In this manner, it was found that the segments of cliff in this coastal zone have heights around 4 meters to 14 meters and inclinations of approximately 40° to 90°.However the constituents soils of the cliffs were classified, in general terms in accordance to Unified Soil Classification System (USCS), as clayey sands or silty sands, clays of low plasticity, clayey gravels and poorly graduaded sands. The most variegated and clayey soils belong to base of the cliff. The stability analysis showed that the safety factors ranged in section 01, from 1.92 to 4.93, in the section 02, from 1.00 to 1.43, in the section 03, from 1.36 to 1.75 , and section 04, from 1.00 to 3.64. Thus, the sections 02 and 03 were considered more unstable. However, the section 03 can be considered as the most critical section due to the absence of coastal protection structures and the narrow strip of beach.

Petrologia do Plutão Bom Jardim de Goiás (PBJG): implicação na evolução neoproterozoica da Província Tocantins

The Bom Jardim de Goiás Pluton (PBJG) is a semi-circular body, located in the central portion of the Tocantins Province, intrusive into orthogneisses and metassupracrustals of the Arenópolis Magmatic Arc. These metasupracrustals present a low to moderate dipping banding or schistosity, have a low to moderate angle of banding / foliation, defined by mica, andalusite and sillimanite and cordierite, which characterize an amphibolite facies metamorphism. This structure is crosscut by the emplacement of the PBJG rocks. The abrupt nature of the contacts and the absence of ductile structures indicate that the intrusion took place in a relatively cold crust. Under petrographic grounds, the pluton consists mainly of monzodiorites, tonalite and granodiorite, following the low to medium-K calk-alkaline alkaline trend. Rocks of the PBJG have hornblende and biotite as the main mafic phases, besides subordinate clinopyroxene, titanite, epidote and opaque. Late dikes of leucogranite contain only mineral biotite as relevant accessory mineral. One U-Pb zircon dating of a monzodiorite yielded an age of 550 ± 12 Ma (MSWD = 1.06). Whole-rock and mineral chemistry suggest that the studied rocks are calc-alkaline, having evolved by fractional crystallization of Ca- and Fe-Mg minerals under high oxygen fugacity. Using the amphibole-plagioclase geothermometer and the Al-in amphibole geobarometer, we calculate temperatures and pressures of, respectively, 692-791 °C e 2.4-5.0 kbar for the intrusion of the PBJG, which is corroborated by previous metamorphic assemblages in the country rocks. The geological, geochemical and geochronological features of PBJG demonstrate their post-tectonic or post-collisional nature, with emplacement into an already uplifted and relatively cool crust at the end of brasiliano orogeny in this portion of the Tocantins Province.

Este estudo objetivou conhecer a incidência do evento queda e identificar a presença de seus principais fatores de risco. Estudo exploratório, realizado de março a novembro/2009, com aplicação de um formulário sobre quedas em um grupo de idosos. Os dados foram analisados por cálculo de frequências, média e desvio-padrão. Participaram 62 idosos, 41,9% relataram queda nos últimos seis meses, a maioria mulheres. Identificou-se ocorrência de agravos concomitantes: visão regular, audição boa, polifarmácia, IMC normal, forte força de preensão palmar e condições dos pés adequadas. Na maioria dos que caiu, o desequilíbrio foi apontado como principal motivo. A queda ocorreu mais no período da manhã, em local de piso áspero e seco, sem degraus, rampas ou tapetes, iluminação adequada e o tipo de calçado mais utilizado foi chinelo de borracha. Percebe-se a alta ocorrência das quedas na população idosa, fato que fundamenta a necessidade de avaliação das condições de risco envolvidas

Cuidados de enfermagem ao paciente em pós-operatório de prostatectomia: revisão integrativa

Este estudo trata-se de revisão integrativa da literatura com objetivo de sintetizar o conhecimento produzido em artigos sobre os cuidados de enfermagem aos pacientes em pós-operatório de prostatectomia. Para seleção dos artigos foram consultadas cinco bases de dados – SCOPUS, CINAHL, PUBMED, LILACS e Cochrane – sendo incluídos dezenove artigos. Os resultados mostram estudos que se enquadram nos níveis II, IV, V, VI e VII de evidência, a maioria realizada nos Estados Unidos durante os anos de 1999 a 2011. Os cuidados de enfermagem identificados foram agrupados em seis categorias: acompanhamento psicológico, orientações pós-operatórias, tratamento da disfunção erétil, tratamento da incontinência urinária, tratamento da dor e tratamento da hiponatremia. Conclui-se que os estudos com maior nível de evidência identificado recomendam cuidados de enfermagem centrados no acompanhamento psicológico, nas orientações do período pós-operatório e no tratamento da disfunção erétil. Destaca-se ainda que tais recomendações concentram-se, sobretudo, nas ações de apoio emocional e educativo

Etnobiologia do boto cinza (Sotalia guianensis, van Bénéden, 1864) por comunidades pesqueiras do Rio Grande do Norte, Basil

Ethnobiology studies Local Ecological Knowledge (LEK) as well as the use and management of natural resources by local communities in order to understand how the environment is perceived, known and classified by human groups. In fishing communities, LEK adds empirical information about the biology of aquatic species and complements scientific findings, especially when it is difficult to obtain factual information during studies on cetaceans, whose behavior is essentially underwater. Cetaceans (whales and dolphins) are constantly threatened by human activities, especially by accidental capture of small coastal species, as in the case of the estuarine dolphin (Sotalia guianensis), object of this study. Ethnobiological researches in fishing communities are of great importance and can clarify aspects of the biology and conservation of this species. Although extensively studied throughout its distribution range, there are still gaps in the knowledge about S. guianensis. Therefore, fishers local ecological knowledge becomes an additional tool to get and confirm information about S. guianensis. This study evaluated the LEK of artisanal fishers who are daily exposed to local population of S. guianensis, through the use of semistructured interviews (N=116). The interviewed fishers were asked about the biology and popular classification of S. guianensis and about possible interactions between this dolphin and them. The studied communities were located in Tibau do Sul (n=39), Pipa (n=36) and Baía Formosa (n=41), all on the south coast of Rio Grande do Norte, Brazil. The study was based on the assumption that differences in fishers LEK among those communities would be caused by both the variety of fishing environments (lagoon/estuary and ocean) and the intensity of tourism activities. Fishers knowledge is expressive and differed among the studied communities depending on the topic investigated. Fishers correctly reported the habitat, distribution, seasonality and behavioral particularities of S. guianensis. Tourism mainly affected the naming of the species. The study results also suggest that marine fishers have greater knowledge about the species than the estuarine/lagoon ones. Local populations accumulate empirical knowledge according to their environment. Hence, it is important to take into account both empirical knowledge and popular participation in management systems, in order to maintain information sharing among communities

As condições do trabalho docente: um estudo em escolas da rede municipal de Currais Novos-RN (2009 a 2012)

This work, named Teaching conditions: a study in municipal schools of Currais Novos RN (2009 to 2012) aims to analyze the status of teaching in schools in the municipality of Currais Novos RN in the period ranging from 2009 - 2012, considering infrastructure, initial and continued training and intensification and casualization of teaching factors in the context of the 1990s educational reformations. It, also, assumes that teaching is a constitutive part of capitalist society, and has been reconfigured with based on the new requirements demanded by the labor market. In order to conduct this study the considered data included the survey research Teaching Work in Basic Education in Brazil (2009 to 2010) , held in seven Brazilian states being: Pará, Rio Grande do Norte, Minas Gerais, Goiás, Paraná, Santa Catarina and Espírito Santo. Specifically selected for deepening of the study, there were schools in the municipality of Currais Novos in which semi-structured interviews were performed with teachers of the said municipality. This research is constituted of a qualitative and quantitative approach whose survey instruments adopted were, namely: documental research, literature review, interviews and surveys. The obtained data analysis allows us to infer that the teaching work performed by teachers in the states which participated in the survey has been influenced the changes in the labor market and educational reformations and has been taking on characteristics such as flexibility, tendency to precariousness and intensification; and this trend is also present in schools that were surveyed in the municipality of Currais Novos. As pertaining to the teachers conditions in classroom, these signs are more evident, considering that they had their duties and responsibilities extended beyond the classroom environment. The data also show that in general working conditions of teachers in national, state and local levels are unprofitable and heterogeneous, increasingly deepening the gap between school units and education networks. Therefore, the implantation of public policies that enhance the teaching work and improve their working conditions in all dimensions that directly interfere in their work are crucial

There was predominance of females, with civil state married, with age between 29 and 47 years, inserted as nurses in Family Health Strategy 1 to 9 years. All referred satisfaction with work. Emerged 02 main meanings of work, whichever the design of work as a source of human and practical transforming of reality, with the sense of perform an action by the individual facilitator and suffers change. Include the precarious work not only as the absence of links labor and social protection, unlike the thought of the Ministry of Health, similar to the design of the study, the precariousness understood yet as the absence of participation of workers in the spaces work management and running of the work and the absence of structural conditions and infra-structural where the work process takes place. evidenced the totality of nurses inserted in Family Health Strategy by public tender. Refer have labor rights guaranteed. Don´t include under which legal arrangements are governed. The researched reality does not have a policy desprecarização nursing work of Family Health Strategy. Concluded the municipality presents progress and setbacks for the precariousness of work of the nurse of Family Health Strategy. The collective work in health is a challenge in researched reality and the policy of desprecarização of the work of the management of education and work was not evidenced. Despite the implementation of the public tender these professionals have a degree of precariousness of work, with the accumulation gradient of responsibilities, some lack of working conditions in structural aspects, infra-structural and means and instruments

Análise da atividade de trabalho profissional de gerentes de hotel à luz da abordagem da ergonomia

This Masters degree dissertation presents a research that aims at analyzing the activities regarding within a hotel managers work in Natal/RN - Brazil, This Masters degree dissertation presents the research that aims at analyzing the activities regarding the hotel managers work in Natal / RN - Brazil, performing diagnosis of their activities and relating the aspects that impact the quality and productivity of hotel services and managers occupational health. This research is characterized as a case study with a qualitative approach, taking the method of Ergonomic Work Analysis which is the analysis of the managers work activity as a reference to the focus; and combining the use of observational and interactional methods. Ergonomics and macroergonomics are used in this study not only to understand the physical, cognitive and organizational constraints of the manager s duties, but also to characterize the work organizational architecture and design of that hotel. High workload, accumulation of tasks and diversion of functions performed by managers were noticed, increasing thereby the physical and psychological suffering for them. It was found that the activity of managers is characterized by the ambivalence of power, limited autonomy, cooperation, interdependence between managers and the fear of incompetence. It was also noticed that managers devote more time to the day job (37%), another time to sleep (30%), while only 33% of the rest of the day are meant for activities like taking care of health, family, social life and study. Although there are few studies addressing the health and safety of hotel managers, this research revealed that 84% of the surveyed hotel managers complain of musculoskeletal pain which 50% are obese and are 100% sedentary. It was also observed that managers adopt unsuitable postures for carrying out the work activities that contribute to becoming injured or work-related musculoskeletal disorders in the near future. Ergonomic measures were recommended as an investment in the skills and the training of managers, encouraging cooperative work, appropriateness of workload, limiting overtime, preserving the enjoyment of breaks during work and weekly holidays, changing the layout of the work sector , usage of communication technology to prevent displacement, compensatory physical activities, furniture adaptation, among others

Extração e Representação de Conhecimento de Séries Temporais de Demanda de Energia Elétrica Usando TSKR

The opening of the Brazilian market of electricity and competitiveness between companies in the energy sector make the search for useful information and tools that will assist in decision making activities, increase by the concessionaires. An important source of knowledge for these utilities is the time series of energy demand. The identification of behavior patterns and description of events become important for the planning execution, seeking improvements in service quality and financial benefits. This dissertation presents a methodology based on mining and representation tools of time series, in order to extract knowledge that relate series of electricity demand in various substations connected of a electric utility. The method exploits the relationship of duration, coincidence and partial order of events in multi-dimensionals time series. To represent the knowledge is used the language proposed by Mörchen (2005) called Time Series Knowledge Representation (TSKR). We conducted a case study using time series of energy demand of 8 substations interconnected by a ring system, which feeds the metropolitan area of Goiânia-GO, provided by CELG (Companhia Energética de Goiás), responsible for the service of power distribution in the state of Goiás (Brazil). Using the proposed methodology were extracted three levels of knowledge that describe the behavior of the system studied, representing clearly the system dynamics, becoming a tool to assist planning activities

Estudo da circulação hidrodinâmica e da dispersão de óleo na zona costeira entre Macau e Galinhos RN

This paper presents a study on coastal hydrodynamics and the spread of an oil spill in waters off Macau and Galinhos, on the east coast of the state of Rio Grande do Norte in Northeast Brazil. This area has a very marked coastal dynamic owing to the complexity of its geomorphological features, developed in a regime of semidiurnal mesotides involving reefs, spits, estuaries, mangroves, lakes and dunes. The region also plays an important role in the socioeconomic development of the state, given that the production of oil, natural gas, salt and shrimp is concentrated there. The series of oil platforms is interconnected by a pipeline system that carries oil to the local terminal. This pipeline could leak at any moment, causing immense ecological damage. To gauge the risks of an oil leak and resulting contamination of the coastal region, two hydrodynamic scenarios were simulated. The results obtained were used to implement a contaminant transport model with the creation of various oil leak scenarios modeled at different volumes (from small to large) and intensities (sporadic and continuous), at points considered critical for the model (on two platforms and at two pipeline intersections), under different wind (summer and winter) and tidal (high and low at new, full and quarter moon phases) conditions. The use of hydrodynamic circulation computer models as a tool for representing a real project design has been increasingly frequent in recent years, given that they enable the realistic simulation of the hydrodynamic circulation pattern in bodies of water and an analysis of the impacts caused by contaminants released into the water. This study used the computer models contained in SisBAHIA®, in continuous development in the area of Coastal Engineering and Oceanography at COPPE/UFRJ
