No setor hospitalar, o marketing compõe um grupo interdependente de serviços e tem como objetivo principal aproximar clientes - externos, internos e corpo gestor -, através de estratégias específicas que promovem satisfação e qualidade. Esta organização possui uma larga diversidade de profissionais da saúde e o marketing, neste sentido, auxilia no processamento de seus serviços de forma a lapidá-los sob a ótica do cliente, buscando efetividade e produtividade. Neste cenário encontra-se o enfermeiro, cujo trabalho é composto pelas dimensões cuidar, gerenciar, educar/pesquisar, que se entrelaçam e caracterizam o serviço deste profissional. No entanto, costumeiramente, a enfermagem não declara o marketing como uma ferramenta estratégica ao seu processo de trabalho – fato verificável na exploração de publicações científicas -, e, paralelamente, depara-se com empecilhos na execução de seu trabalho que podem comprometer a sua excelência. Assim, este estudo busca analisar a relação do marketing com o trabalho do enfermeiro nas dimensões cuidar, gerenciar, ensinar/pesquisar. Para sua efetivação, optou-se pelo referencial metodológico Estudo de Caso, onde o fenômeno é verificado como ocorre em seu cenário real. Assim, a coleta, caracterizada por pesquisador e unidade únicos, ocorreu em um hospital universitário, geral e público no sul do país que declara publica e virtualmente o marketing institucional. Como fontes de evidência, foram utilizadas: entrevista focada com quatro sujeitos de áreas estratégicas para esta pesquisa; análise de documentação criada pela assessoria de marketing e observação direta. O tratamento e a análise dos dados ocorreram por meio da Análise Temática, que possibilitou a exposição dos resultados através de dois artigos: “A relação do marketing com o processo de trabalho do enfermeiro na dimensão cuidar” e “A relação do marketing com o processo de trabalho do enfermeiro nas dimensões gerenciar e educar/pesquisar”. Os resultados evidenciaram que o marketing no cuidar - auxilia a efetividade do cuidado através de novas estratégias de comunicação com o usuário, produz materiais elucidativos, lúdicos para sua continuação e manutenção e o divulga no meio intra e extra-hospitalar; no gerenciar - auxilia a o enfermeiro a ter um método mais inovador e criativo, a focar no cliente e no bom relacionamento interpessoal com a equipe; no educar/pesquisar - cria canais de comunicação interna e campanhas únicas que, além de auxiliar na realização da educação permanente e na atualização de enfermeiros, propicia meios para transmitir novos achados científicos à prática da enfermagem hospitalar. Através deste estudo, percebeu-se que ações de marketing podem contribuir para a efetividade do trabalho do enfermeiro em suas facetas dimensionais, aproximando este agente de saúde do usuário ao qual seu serviço é destinado e da gestão da organização, propiciando a este profissional maior visibilidade e valorização no espaço hospitalar e social.

O aparecimento da fibra de vidro deve-se à pesquisa de novos materiais. No século XIX, as fibras de vidro foram pela primeira vez tecidas. Só mais tarde, durante o século XX, com o desenvolvimento de resinas foi possível produzir a fibra de vidro como material compósito. Ainda durante a 2ª Guerra Mundial foi construído um avião de combate em fibra de vidro. Desde então sofreu um grande desenvolvimento, tendo sido aplicada nas mais diversas indústrias. Recentemente, a fibra de vidro tem sido também aplicada em estruturas na construção civil. Nos últimos anos tem havido uma crescente investigação acerca das estruturas de betão armado com armaduras de fibra de vidro (GFRP). A análise de parâmetros como a fendilhação, a deformação e a contribuição do betão entre fendas, é fundamental para a compreensão do comportamento desse material compósito. A aderência entre os varões e o betão é condicionada pela resistência do betão e pela superfície das armaduras, podendo estas propriedades influenciarem a evolução dos parâmetros atrás referidos. Contudo, a investigação neste domínio ainda está pouco desenvolvida e carece de mais estudo, para que seja possível a sua aplicação em estruturas de uma forma mais criteriosa e abrangente. Pretendeu-se conjugar as vantagens do betão estrutural de agregados leves (BEAL), bom desempenho de resistência e a reduzida densidade, com as dos varões de GFRP, sendo necessário estudar o seu comportamento em conjunto para uma boa compreensão dos fenómenos inerentes a esta combinação de materiais. Neste trabalho analisam-se vários parâmetros fundamentais ao comportamento de elementos de BEAL reforçado com varões de GFRP, nomeadamente: a aderência da interface betão-armadura, a fendilhação, tension stiffening effect e a deformação. Para esta análise, considerou-se a variação da resistência mecânica do BEAL, do tipo de armadura de reforço (aço e GFRP) e o diâmetro dos varões. Foi desenvolvido um programa experimental que contempla um total de doze tirantes de betão armado, seis com varões de GFRP e seis com varões de aço, de forma a poder efectuar-se uma comparação directa. Foram também incluídos no programa experimental trinta e seis provetes de ensaios pull out, dezoito com armaduras de fibra de vidro e dezoito com armaduras de aço, igualmente com o objectivo de comparação dos resultados. Na análise dos resultados foi possível verificar as diferenças entre o uso de armaduras de GFRP e de aço nos parâmetros em estudo, assim como a influência da resistência dos BEAL e dos diâmetros das armaduras. Verificou-se que a largura de fendas, bem como as deformações nos tirantes com armaduras de GFRP foram superiores às observadas com armaduras de aço. No que diz respeito à aderência foram observadas menores tensões nas armaduras de GFRP.

Leptospirosis is a worldwide zoonosis of considerable medical and economical importance that affects humans in both urban and rural contexts, as well as domestic animals and wild fauna. Leptospira interrogans is the causative agent and is transmitted to humans by indirect contact with contaminated soil or water. The clinical syndromes include sub clinical infection, self-limited anicteric febrile illness, and severe and potentially fatal illness, known as Weil´s syndrome. In developed countries, leptospirosis is related to occupational or recreational activities while in developing countries, outbreaks occur during floods. In those regions, traditional strategies to prevent the transmission are difficulties to be implemented because of costs and lack of community acceptance. In addition, no efficient vaccine is available for human use. Several studies have suggested that chemoprophylaxis with doxycycline pre and post-exposure may be effective to prevent leptospirosis. Leptospirosis has been reported in rural areas of the State of Rio Grande do Norte, Brazil since 1985 in rice farmers who present the anicteric illness. The disease cause great social and economics impact. The study was conducted in São Miguel where an epidemic of leptospirosis in rice farmers was reported. The main objective was to determine the efficacy of doxycycline in preventing Leptospira exposure. A taxa de soroprevalência de leptospirose na população estudada antes e após a colheita foi de 14,2% (n=22) e de 16.6% (n=27) respectivamente. Anti-Leptospira serology was determined for 61 subjects in two instances, pre and post-exposure to potential contaminated water. There was an increased risk of 29.0 per cent in acquiring infection for individuals that did not use doxycycline. In addition, an increased risk of 30.0 % observed in farmers who did not use protection when exposed to Leptospira. The adhesion to preventive chemoprophylaxis was 55.7%. Therefore doxycycline, under specific circunstances appears to be an effective alternative to protect against leptosprirosis infection. A large sample composed of individuals to adhere to preventive therapy is needed to define time, dosage and length of use of doxycycline in this area

Forecast is the basis for making strategic, tactical and operational business decisions. In financial economics, several techniques have been used to predict the behavior of assets over the past decades.Thus, there are several methods to assist in the task of time series forecasting, however, conventional modeling techniques such as statistical models and those based on theoretical mathematical models have produced unsatisfactory predictions, increasing the number of studies in more advanced methods of prediction. Among these, the Artificial Neural Networks (ANN) are a relatively new and promising method for predicting business that shows a technique that has caused much interest in the financial environment and has been used successfully in a wide variety of financial modeling systems applications, in many cases proving its superiority over the statistical models ARIMA-GARCH. In this context, this study aimed to examine whether the ANNs are a more appropriate method for predicting the behavior of Indices in Capital Markets than the traditional methods of time series analysis. For this purpose we developed an quantitative study, from financial economic indices, and developed two models of RNA-type feedfoward supervised learning, whose structures consisted of 20 data in the input layer, 90 neurons in one hidden layer and one given as the output layer (Ibovespa). These models used backpropagation, an input activation function based on the tangent sigmoid and a linear output function. Since the aim of analyzing the adherence of the Method of Artificial Neural Networks to carry out predictions of the Ibovespa, we chose to perform this analysis by comparing results between this and Time Series Predictive Model GARCH, developing a GARCH model (1.1).Once applied both methods (ANN and GARCH) we conducted the results' analysis by comparing the results of the forecast with the historical data and by studying the forecast errors by the MSE, RMSE, MAE, Standard Deviation, the Theil's U and forecasting encompassing tests. It was found that the models developed by means of ANNs had lower MSE, RMSE and MAE than the GARCH (1,1) model and Theil U test indicated that the three models have smaller errors than those of a naïve forecast. Although the ANN based on returns have lower precision indicator values than those of ANN based on prices, the forecast encompassing test rejected the hypothesis that this model is better than that, indicating that the ANN models have a similar level of accuracy . It was concluded that for the data series studied the ANN models show a more appropriate Ibovespa forecasting than the traditional models of time series, represented by the GARCH model

Due to the appreciation of family farming by the Brazilian Federal Government, the Technical Assistance and Rural Extension was induced to restructure and act in a more participative way, culminating in the National Policy of Technical Assistance and Rural Extension (PNATER), changing the profile of technology transfer and knowledge (diffusionism) for an action that uses participatory methodologies focused on exchange of knowledge between farmers and technicians. The process of discussion of the trends of ATER brought the New ATER , with the recognition of agroecology as the main guidance. This research aimed to analyze methods of public ATER developed by institutions of Rio Grande do Norte, under the guidance of New ATER. The research is qualitative. Secondary data were collected through documental research and literature. Primary data were collected through a set of interviews applied to representatives of public institutions ATER, namely EMATER-RN, Diaconia and AACC and representatives of organizations that receive public ATER. The research showed the difficulties of EMATER-RN in implementing of New ATER due to lack of infrastructure and low adherence of the new form of technical assistance and rural extension. It was shown also that the AACC and Diaconia act with ATER through projects with implementation deadlines set, often interrupting ATER while communities are still in need of assistance

A comunicação é um instrumento importante da prática médica e em especial da medicina geral e familiar, pelo seu âmbito menos específico. A abordagem biopsicossocial para ser eficaz necessita de uma forte componente comunicacional nas diversas fases da relação médico doente, nomeadamente, na consulta, nas actividades de prevenção da doença e de educação para a saúde, na relação com os familiares do doente. A comunicação médico-doente influencia a aderência à terapêutica pelo doente e os seus índices de satisfação com a consulta. A comunicação desempenha, também, um papel importante, conforme é adequada ou não, no desencadear ou na prevenção do stress e burnout do(a) médico(a), que são aspectos directamente relacionados com o seu bem-estar ou absentismo por doença. A comunicação é uma componente central das estratégias de coping para as situações difíceis do quotidiano médico como as emoções associadas à doença, sofrimento e morte. Devido ao papel fulcral que a comunicação tem na prática médica, considera-se que a formação em comunicação deve ser mais valorizada, nos diversos níveis, pré ou pós-graduado.

The system built to characterize electrodes and, consequently, deposited fine films are constituted by a hollow cathode that works to discharges and low pressures (approximately 10-3 to 5 mbar), a source DC (0 to 1200 V), a cylindrical camera of closed borossilicato for flanges of stainless steel with an association of vacuum bombs mechanical and spread. In the upper flange it is connected the system of hollow cathode, which possesses an entrance of gas and two entrances for its refrigeration, the same is electrically isolated of the rest of the equipment and it is polarized negatively. In front of the system of hollow cathode there is a movable sample in stainless steel with possibility of moving in the horizontal and vertical. In the vertical, the sample can vary its distance between 0 and 70 mm and, in the horizontal, can leave completely from the front of the hollow cathode. The sample and also the cathode hollow are equipped with cromel-alumel termopares with simultaneous reading of the temperatures during the time of treatment. In this work copper electrodes, bronze, titanium, iron, stainless steel, powder of titanium, powder of titanium and silício, glass and ceramic were used. The electrodes were investigated relating their geometry change and behavior of the plasma of the cavity of hollow cathode and channel of the gas. As the cavity of hollow cathode, the analyzed aspects were the diameter and depth. With the channel of the gas, we verified the diameter. In the two situations, we investigated parameters as flow of the gas, pressure, current and applied tension in the electrode, temperature, loss of mass of the electrode with relationship at the time of use. The flow of gas investigated in the electrodes it was fastened in a work strip from 15 to 6 sccm, the constant pressure of work was among 2.7 to 8 x 10-2 mbar. The applied current was among a strip of work from 0,8 to 0,4 A, and their respective tensions were in a strip from 400 to 220 V. Fixing the value of the current, it was possible to lift the curve of the behavior of the tension with the time of use. That curves esteem in that time of use of the electrode to its efficiency is maximum. The temperatures of the electrodes were in the dependence of that curves showing a maximum temperature when the tension was maximum, yet the measured temperatures in the samples showed to be sensitive the variation of the temperature in the electrodes. An accompaniment of the loss of mass of the electrode relating to its time of use showed that the electrodes that appeared the spherical cavities lost more mass in comparison with the electrodes in that didn't appear. That phenomenon is only seen for pressures of 10-2 mbar, in these conditions a plasma column is formed inside of the channel of the gas and in certain points it is concentrated in form of spheres. Those spherical cavities develop inside of the channel of the gas spreading during the whole extension of the channel of the gas. The used electrodes were cut after they could not be more used, however among those electrodes, films that were deposited in alternate times and the electrodes that were used to deposit films in same times, those films were deposited in the glass substrata, alumina, stainless steel 420, stainless steel 316, silício and steel M2. As the eletros used to deposit films in alternate time as the ones that they were used to deposit in same times, the behavior of the thickness of the film obeyed the curve of the tension with relationship the time of use of the electrode, that is, when the tension was maximum, the thickness of the film was also maximum and when the tension was minimum, the thickness was minimum and in the case where the value of the tension was constant, the thickness of the film tends to be constant. The fine films that were produced they had applications with nano stick, bio-compatibility, cellular growth, inhibition of bacterias, cut tool, metallic leagues, brasagem, pineapple fiber and ornamental. In those films it was investigated the thickness, the adherence and the uniformity characterized by sweeping electronic microscopy. Another technique developed to assist the production and characterization of the films produced in that work was the caloteste. It uses a sphere and abrasive to mark the sample with a cap impression, with that cap form it is possible to calculate the thickness of the film. Through the time of life of the cathode, it was possible to evaluate the rate of waste of its material for the different work conditions. Values of waste rate up to 3,2 x 10-6 g/s were verified. For a distance of the substratum of 11 mm, the deposited film was limited to a circular area of 22 mm diameter mm for high pressures and a circular area of 75 mm for pressure strip. The obtained films presented thickness around 2,1 µm, showing that the discharge of arch of hollow cathode in argon obeys a curve characteristic of the tension with the time of life of the eletrodo. The deposition rate obtained in this system it is of approximately 0,18 µm/min

The partial fixed prosthodontics restoration is used to rehabilitate form and function of partial or total compromised teeth, having to remain permanently joined to remainder tooth. The most useful material on prosthodontics is the feldspar porcelain, commercialized as aluminosilicate powders. Dental porcelains are presented with limited mechanical properties to rehabilitate extensive spaces. The association with Ni-Cr metallic systems (metal-ceramic system) allows that the metallic substructure compensates the fragile porcelain nature, preserving the thermal insulation and aesthetics desirable, as well as reducing the possibility of cracking during matication efforts. Cohesive flaws by low mechanical strength connect the metallic substructure to the oral environment, characterized by a electrolytic solution (saliva), by aggressive temperature, pH cyclic changes and mechanical requests. This process results on ionic liberation that could promote allergic or inflammatory responses, and/or clinical degradation of ceramometal system. The aim of this study was to evaluate the presence of an intermediate titanium layer on the microscopic fracture behavior of porcelains on ceramometal systems. Plasma deposition of titanium films result in regular passivating oxide layers which act as barriers to protect the metallic substrate against the hazardous effects of corrosive saliva. Tribocorrosion tests were performed to simulate the oral environment and mechanical stress, making it possible the early detection of crack formation and growth on metal-ceramic systems, which estimate the adherence between the compounds of this system. Plain samples consisting of dental feldspar porcelain deposited either onto metallic substrates or titanium films were fired and characterized by scanning electron microscopy. The result showed that the titanium film improved the adherence of the system compared to conventional metal-ceramic interfaces, thus holding crack propagation

Cells the solid oxide fuel are systems capable to directly convert energy of a chemical reaction into electric energy in clean, quiet way and if its components in the solid state differentiate of excessively the techniques for having all. Its more common geometric configurations are: the tubular one and to glide. Geometry to glide beyond the usual components (anode, cathode and electrolyte) needs interconnect and sealant. E the search for materials adjusted for these components is currently the biggest challenge found for the production of the cells. The sealants need to present chemical stability in high temperatures, to provoke electric isolation, to have coefficient of compatible thermal expansion with the excessively component ones. For presenting these characteristics the glass-ceramics materials are recommended for the application. In this work the study of the partial substitution of the ZrO2 for the Al2O3 in system LZS became it aiming at the formation of system LZAS, this with the addition of natural spodumene with 10, 20 and 30% in mass. The compositions had been casting to a temperature of 1500°C and later quickly cooled with the objective to continue amorphous. Each composition was worn out for attainment of a dust with average diameter of approximately 3μm and characterized by the techniques of DRX, FRX, MEV, dilatometric analysis and particle size analysis. Later the samples had been conformed and treated thermally with temperatures in the interval between 700-1000 °C, with platform of 10 minutes and 1 hour. The analyses for the treated samples had been: dilatometric analysis, DRX, FRX, electrical conductivity and tack. The results point with respect to the viability of the use of system LZAS for use as sealant a time that had presented good results as isolating electric, they had adhered to a material with similar α of the components of a SOFC and had presented steady crystalline phases
