Avaliação das condições de trabalho em Hospitais de Natal, Rio Grande do Norte, Brasil

Buscou-se identificar como os profissionais de saúde avaliam as condições de trabalho em hospitais de diferentes naturezas, e verificar como estas condições interferem na satisfação laboral. A amostra foi composta por 213 profissionais de diferentes categorias. A análise dos resultados evidenciou um perfil distinto entre os hospitais no tocante as condições de trabalho. De forma geral, apontou as menores médias no hospital estadual, enquanto as maiores foram observadas no hospital filantrópico; resultado que corrobora o atual cenário da saúde pública do País. Ressalta-se ainda, uma associação significativa entre satisfação no trabalho e as variáveis renda familiar e hospital em que o profissional atua. Acredita-se que os conflitos nesse cenário são inevitáveis, frente à precária estrutura de algumas instituições públicas, contudo, são previsíveis e passíveis de solução se o hospital dispuser de um canal de expressão livre e acessível a todos os agentes.

Aplicação da análise exploratória de dados na discriminação geográfica do quiabo do Rio Grande do Norte e Pernambuco

Foram analisadas amostras de quiabo dos municípios de Caruaru e Vitória de Santo Antão, em Pernambuco, assim como nos municípios de Ceará-Mirim, Macaíba e Extremoz no estado do Rio Grande do Norte. A aplicação de dois métodos de análise exploratória de dados: Análise de Componentes principais - PCA e Análise de Agrupamentos Hierárquicos - HCA permitiu a discriminação geográfica do quiabo proveniente dos dois estados.

Hydrobiidae (Gastropoda, Neotaenioglossa, Rissooidea) da planície costeira do Rio Grande do Sul, Brasil

A família Hydrobiidae, que apresenta maior diversidade entre os moluscos límnicos e estuarinos, com mais de 300 gêneros e cerca de mil espécies Recentes, constitui-se em um importante componente biótico de águas continentais. A monofilia da família ainda é duvidosa, uma vez que a maioria das espécies é apenas conhecida pelos caracteres da concha, opérculo, pênis e rádula, insuficientes para traçar relações filogenéticas em Hydrobiidae. Apresentam alta diversidade específica e genérica, nos diferentes continentes, sendo a América do Sul uma exceção, com 120 espécies em sete gêneros recentes, enquanto que na América do Norte as mais de 200 espécies da família estão distribuídas em 40 gêneros, como registrado pela literatura. Estes caracóis acham-se distribuídos ao longo de toda Planície Costeira do Rio Grande do Sul, Brasil. A presente tese objetiva: identificar, definir e redefinir os hidrobiideos ocorrentes em ambientes límnicos e estuarinos da Planície Costeira do Rio Grande do Sul, a partir de coleções científicas e amostragens de material vivo. Examinou-se Hydrobiidae das coleções: Museu Museu de Ciências Naturais da Fundação Zoobotânica do Rio Grande do Sul (MCNZ); Departamento de Zoologia da Universidade Federal do Rio Grande do Sul (UFRGS); coleção particular de Rosane Lanzer (RL); The Academy of Natural Sciences of Philadelphia (ANSP); The Natural History Museum, Londres (BMNH). Realizou-se coleta no rio Hercílio em Santa Catarina, nas lagoas Itapeva, Tramandaí, Rondinha, Fortaleza e arroio do Carvão (bacia do rio Maquiné) no Rio Grande do Sul, utilizando peneira com malha de 1mm de abertura para a amostragem. Material coletado está depositado na coleção de moluscos da UFRGS. Obtiveram-se dados conquililógicos, conquiliometricos e morfoanatômicos in vivo - cabeça-pé, cavidade palial, sistemas reprodutores feminino e masculino e rádula. As ilustrações correspondem a desenhos da morfo-anatomia, e fotomicrografias da concha, opérculo, cabeça-pé e rádula. Foram inventariados 145 táxons do grupo da espécie de Hydrobiidae, descritos para a América do Sul, acrescidos de lista sinonímica e informações morfológicas de material-tipo. Registram-se os seguintes hidrobídeos para Planície Costeira do Rio Grande do Sul: Heleobia australis (Orbingy, 1835) (rio Tramandaí, lagunas Tramandaí e Armazém, lagoas Custódia e Paurá e laguna dos Patos); Heleobia bertoniana (Pilsbry, 1911) (lagoa Caieiras); Heleobia cuzcoensis (Pilsbry, 1911) ( lagoa Rondinha); Heleobia doellojuradoi (Parodiz, 1960) (lagoas Figueiras, Bojuru Velho e Mangueira); Heleobia parchappei (Orbigny, 1835) (lagoas Itapeva, Quadros, Ramalhete, Negra, Malvas, Marcelino, Quintão, Barro Velho, Moleques, Peixe, Jacaré, Mangueira e Laguna dos Patos); Heleobia xi sp. (lagoas Itapeva, Quadros, Malvas, Palmital, Pinguela, Lessa, Peixoto, Marcelino, laguna Tramandaí, lagoas Gentil, Manuel Nunes, Fortaleza, Rondinha, Cerquinha, Rincão das Éguas, Cipó, Porteira, Capão Alto, Quintão, Charqueadas, Barro Velho, São Simão, Veiana, laguna Mirim, lagoas Nicola e Jacaré); Potamolithus kusteri (Strobel, 1874) (arroio Carvão); Potamolithus philippianus Pilsbry, 1911 (lagoas Itapeva e Figueiras). Registra-se pela primeira vez para o Brasil, H. bertoniana, H. doelojuradoi e P. kusteri; para o Rio Grande do Sul, P. philippianus; e para a Planície Costeira, H. cuzcoensis. A partir de topótipos, é redescrito o táxon Potamolithus catharinae Pilsbry, 1911, assinalado na literatura para o litoral norte da Planície Costeira do Rio Grande do Sul, cuja ocorrência não é confirmada. Heleobia charruana (Orbigny, 1835), registrada na literatura para o litoral norte do RS, não tem sua ocorrência confirmada. Transfere-se o gênero monotípico Parodizia, arrolado entre os hidrobídeos, para Pyramidellidae (Gastropoda, Heterobranchia), a partir da morfologia das partes moles, desconhecidas até o presente. A morfologia do pênis de exemplares de Potamolithus kusteri (Strobel, 1874), do arroio Carvão, justifica sua remoção de Heleobia para Potamolithus. Heleobia australis nana (MARCUS & MARCUS, 1963) é considerada sinônimo de H. australis, por tratar-se de táxons morfoanatomicamente iguais. As distintas dimensões da concha (2,0 a 8,4 mm) de populações, ao longo da distribuição da espécie (Rio de Janeiro á Baía San Blás), decorrem de fatores ambientais, provavelmente relacionados com o grau de variação da salinidade.

Hidrocarbonetos policíclicos aromáticos em sedimentos de fundo do estuário do rio Potengi, região da grande Natal (RN): implicações ambientais

Estuaries are environments prone to the input of chemical pollutants of various kinds and origins, including polycyclic aromatic hydrocarbons (PAHs). Anthropogenic PAHs may have two possible sources: pyrolytic (with four or more aromatic rings and low degree of alkylation) and petrogenic (with two and three aromatic rings and high degree of alkylation). This study aimed to evaluate the levels, distribution and possible sources of polycyclic aromatic hydrocarbons in the estuary of the Potengi river, Natal, Brazil. Samples of bottom sediments were collected in the final 12 km of the estuary until its mouth to the sea, where the urbanization of the Great Natal is more concentrated. Sampling was performed on 12 cross sections, with three stations each, totaling 36 samples, identified as T1 to T36. The non alkylated and alkylated PAHs were analyzed by gas chromatography coupled to mass spectrometry (GC / MS). PAHs were detected in all 36 stations with total concentration on each varying 174-109407 ng g-1. These values are comparable to those of several estuarine regions worldwide with high anthropogenic influence, suggesting the record of diffuse contamination installed in the estuary. PAHs profiles were similar for most stations. In 32 of the 36 stations, low molecular weight PAHs (with 2 and 3 ring: naphthalene, phenanthrene and their alkylated homologues) prevailed, which ranged from 54% to 100% of the total PAH, indicating that leaks, spills and combustion fuels are the dominant source of PAH pollution in the estuary. The level of contamination by PAHs in most stations suggests that there is potential risk of occasional adverse biological effects, but in some stations adverse impacts on the biota may occur frequently. The diagnostic ratios could differentiate sources of PAHs in sediments of the estuary, which were divided into three groups: petrogenic, pyrolytic and mixing of sources. The urban concentration of the Great Natal and the various industrial activities associated with it can be blamed as potential sources of PAHs in bottom sediments of the estuary studied. The data presented highlight the need to control the causes of existing pollution in the estuary

Hidrocarbonetos alifáticos em sedimentos de fundo do estuário do Rio Potengi, grande Natal (RN): implicações ambientais

The Potengi river estuary is located in the region of Natal (RN, Brazil), comprising a population of approximately 1,000,000 inhabitants. Besides the dominant urban presence, the estuary has fragments of mangrove forest. The objective of this study is to determine the aliphatic hydrocarbons found in the bottom sediments of this estuary, identifying their levels, distribution and their possible origins through the diagnostic rates, indexes and results comparisons with the local anthropic and natural characteristics. The samples were obtained according to a plan that allowed sampling of the estuary up to 12 km upstream from it as mounth. 36 stations were selected, grouped into 12 cross sections through the course of the river and spaced on average by 1 km. Each section consisted of three stations: the right margin, the deepest point and the left margin. The hydrocarbon n-alkanes from C10 to C36, the isoprenoids pristane and phytane, the unresolved complex mixture (UCM) and the total resolved hydrocarbons were analyzed by gas chromatography. N-alkanes, pristane, phytane and UCM were detected only at some stations. In the other, the concentration was below the detection limit defined by the analytical method (0.1 mg / kg), preventing them from being analyzed to determine the origin of the material found. By using different parameters, the results show that the estuary receives both the input of petrogenic hydrocarbons, but also of biogenic hydrocarbons, featuring a mixture of sources and relatively impacted portions. Based on the characteristics and activities found in the region, it is possible to affirm that petrogenic sources related to oil products enter the estuary via urban runoff or boats traffic, boat washing and fueling. Turning to the biogenic source, the predominant origin was terrestrial, characterized by vascular plants, indicating contribution of mangrove vegetation. It was evident the presence of, at specific points in the estuary, hydrocarbon pollution, and, therefore is recommended the adoption of actions aimed at interrupting or, at least, mitigating the sources potentially capable of damp petrogenic hydrocarbons in the estuary studied.

Aptidão física relacionada à saúde de escolares Norte- Rio-Grandenses

O sedentarismo é cada vez mais acentuado entre os adolescentes em todo o mundo. Objetivou-se neste estudo analisar o estado nutricional e a aptidão física de escolares norte-rio-grandenses. Participaram 2065 sujeitos, selecionados aleatoriamente (Masc = 1066, Fem = 999) (Natal n=1158; Mossoró n= 312; Lajes n= 231), divididos em três grupos etários pelos estágios maturacionais: 10 a 12 anos, 13 a 14 anos e _ 15 anos. Foi avaliada a composição corporal (IMC, dobras cutâneas tríceps e subescapular); o hábito alimentar (questionário de prevalência do consumo por grupo alimentar); o índice de atividade física (questionário Baeck) e o nível de aptidão física (testes do salto em distância, flexibilidade, resistência abdominal e cardiovascular). Utilizando-se a estatística descritiva, testes de médias pela análise dos intervalos de confiança, o teste de Kruskall-Wallis, teste t, o Qui2 e o coeficiente de contingência. Encontraram-se diferenças significativas com p < 0001 na distribuição do índice de massa corporal (n = 1701); Região Leste Potiguar (RLP) com excesso de peso e obesidade de 16,8 % e 15,2 %, a Região Oeste 16,3% e 9,6 % e a Região Central 10,4 % e 3,9 %, com as escolas privadas contribuindo significativamente na prevalência dessas variáveis nas RLP e ROP com p < 0,003 e p < 0,001 respectivamente. O hábito alimentar demonstrou que 98,3% dos sujeitos consomem alimentos do grupo das massas 98,3%; cereais 97,7%; laticínios 94,7%; frutas 92,3%; gorduras 88,3% e as hortaliças 61,6%, não havendo diferenças significativas no consumo alimentar entre o tipo de escolas e gênero (n = 300). No índice de atividade física habitual há diferenças entre esses respectivos extratos: 2,65±0,78 e 2,81±0,80 (p < 0,014) e 2,89±0,82 e 2,57±0,78 (p < 0,001), com as práticas de atividades esportivas, programas de exercícios físicos e lazer ativo mais significativo em escolas privadas 2,85 ± 1,06 e 3,37±1,26 (p < 0,001) em prol do sexo masculino com 3,47±1,24 e 2,75±1,03 (p <0,001). Resistência abdominal ( =19) e força de membros inferiores ( =128,5 cm) foram classificadas como muito fraco , a flexibilidade ( =26,9 cm) razoável e resistência geral ( =1439 m) como bom . Conclui-se que o hábito alimentar e o baixo índice de atividade física habitual influenciam negativamente os índices da aptidão física relacionada à saúde dos escolares, com menor incidência em instituições privadas em função das práticas esportivas. Este estudo apresenta relação de interface multidisciplinar, tendo o seu conteúdo uma aplicação nos campos da Medicina, Nutrição e Educação Física

Palmyra Wanderley e a educação da mulher no cenário Norte-rio-grandense (1914 -1920)

The present work has the intention to analyze the contribution of the writer and journalist Palmyra Guimarães Wanderley to the education, throughout her writings in the period between 1914 to 1920. I search through her journalist writings produced in the feminine magazine Via Láctea (1914-1915) her idealization, and as in the newspaper A República e Diário de Natal, in the decade of 1920 establishing relationships with education, mostly because of her production in the pages of the paper articles regarding feminine education and women condition. At the same time I sketch the biographic profile of Palmyra Wanderley relating her to the historical moment that she lived. To achieve the proposed goals I begin with a documental research within the available archives and use other sources like pictures and interviews with her relatives. The results of the research show that the worry of Palmira Wanderley with the education in our state, goes beyond her published writings in magazines and newspapers. She has been ahead of Escola de Comércio Feminino and Aliança Feminina, she has also done a conference in the House of the Young Single Ladies' Protection (Casa de Proteção às Moças Solteiras), institution of the Aliança s responsibility that offered shelter, food, formal and religious education to the workers of the Fabric Factory of Natal (Fábrica Tecidos de Natal). Her involvement evidences her contribution to the historiography of the education in Rio Grande do Norte, specially the history of women education ensuring her presence in the day by day history

Avaliação da eficiência da remoção de matéria orgânica e microbiológica de três sistemas de lagoas de estabilização em série na Grande Natal-RN: Beira Rio, Jardim Lola I e Jardim Lola II

Waste stabilization ponds are the main technology in use for domestic sewage treatment in Rio Grande do Norte State (RN), northeast Brazil. The are around 80 systems, constructed mainly by municipal city halls, being series comprised by a primary facultative pond followed by two maturation ponds the most used configuration. Due to problems related with the production and destination of sludge and generation of bad odors, the designers have avoided the use of anaerobic lagoons. The majority of systems are rarely monitored to verify their efficiencies and to get new project parameters for future designing. This work has as purpose to make a diagnosis of efficiency of three series of waste stabilization pond series (WSPS) of Jardim Lola 1, Jardim Lola 2 and Beira Rio, located in the North Zone of the city of the Natal/RN, treating domestic raw sewage, on the removal of organic matter and thermotolerant coliform, comparing the operational conditions of the systems this inside of the bands foreseen in the project, through parameters BOD5, QOD, thermotolerant coliforms, dissolved oxygen, pH, temperature, ammoniac nitrogen, total and suspended solids. The work was carried through in the WSPS, all constituted by a primary facultative pond followed by two maturation ponds. Socioeconomic characteristics of population are predominantly low and all the plants are very near of the contributing basins. The series were monitored from of May the November of 2002, totalizing 20 collections of grab samples of raw sewage and ponds effluents between 8:00 and 9:50 h. The main aspect to be detached by the results was the great concentration of organic matter (BOD and COD) and microorganisms the raw sewage which were around two times more concentrated than those values foreseen one in project. Considering all series the highest removals of organic matter were observed in system Beira Rio (84 and 78% of BOD and COD, respectively), which presented high hydraulic detention time (TDH = 89 days). On the other hand, Jardim Lola 1 and Jardim Lola 2 presented a much lower values of HDT (36 days and 18 days respectively) and their removals of BOD and COD were the same (76% and 60%, respectively). The Beira Rio WSPS, was the most efficient verified in relation to solids and ammonia, proving the great influence of the operational variables such as HDT and applied surface organic loadings on the performance of pond series. Although the treatment plants have reached efficiencies of thermotolerant coliforms around 99,999%, the concentrations in the final effluent can be considered very high for launching in aquatic bodies, particularly those produced by Jardim Lola 1 and Jardim Lola 2 series

Impactos Geoquímicos e Sócio-Ambientais no Estuário do Rio Potengi Região Metropolitana da Grande Natal/RN

The present work studied the problems faced riverine populations of the estuary Potengi, detaching its perception with regard to the environment, as well as in the evaluation of the institucional arrangement that acts in the place. Questionnaires were used in five riverine communities and conducted interviews with agents of public agencies and colonies of fishermen. There is little understanding of the needing to preserve and weakness in the application of the regulation mechanisms

Ambiente institucional e desempenho diferenciado na agropecuária norte-rio-grandense: quais as relações?

This thesis aims to identify how civil servants perceive changes made inthe carrying out of their work after their taking part in the Course forTechnicians in Public Management of the Government of Rio Grande do NorteState. As for the methodological procedures, an exploratory-descriptivequantitative research has been carried out through structured questionnaires appliedto 118 civil servants from the first groups of the Course for Technicians, thusshowing a margin of error of 4.18% to 95% of confidence, according to theprocedures of finite sampling. The table processing and analysis rested uponthe Statistical Package for the Social Sciences SPSS and was carried outthrough univariate, bivariate and multivariate techniques with emphasis on thetechnique called Factor Analysis. It was possible to identify that the level ofsatisfaction of the students was high and there was a clear perception by themthat the course assisted to changes in their work. Through Factor Analysis itwas verified that the factors that may be related to changes in the work of thecivil servants are "Contribution to Society", "Efficiency andEfficacy in the Work Environment", "Applicability of Contents"and "Capacitating for Leadership". The conclusion of the studyindicates that the factors obtained are directly related to the basis of thenew public management by means of guidance toward efficiency and efficacy in aperspective of leadership, the contents of the course being thus made into newattitudes toward work which end up yielding better results for society

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

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
