Ventilação e prescrições urbanísticas: uma aplicação simulada no bairro de Petrópolis em Natal/RN

The present work studies the natural ventilation and its relationship with the urban standards, which establishes the form of occupation and use of the land in our cities. The method simulates the application of the urban standards of the City Master Plan over the last three years. The simulation takes place in the District of Petrópolis, in the city of Natal , Brazil and analyses the effects of the standards of natural ventilation. The formulated hypothesis states that the reductions in the urban spaces between buildings rises up the vertical profile of ventilation, reducing, therefore, the velocity of the wind at the lower levels of the buildings. To develop the study, occupation models were built, using computerized, three-dimensional models. These occupation models were analyzed using the CFD (Computational Fluid Dynamics) code. The conclusion is that the more we reduce the urban space between buildings, the more we reduce the wind speed in constructed areas, increasing, therefore, the possibility to generate heat islands

O descompasso de uma experiência: avaliação do Programa Habitar Brasil na Comunidade África-Natal/RN

This research deals with the evaluation of the Programa do Governo Federal para Urbanização de Favelas Habitar Brasil(1993) carried out in the Africa slum - Redinha neighbourhood in Natal-Rn. This study carried out in period from 2005 to 2006 searches to identify the effects of the actions proposed by Program in 1993-1994 about the current urbanistic configuration of the Africa community. It analyzes the effectiveness in the process of achievement of the considered objectives to habitation, communitity equipments, infrastructure and agrarian regularization. On the evaluation process, it has been as reference the works developed by Adauto Cardoso (2004), Blaine Worthen (2004), Ronaldo Garcia (2001) and Rosângela Paz (2006). About the Habitational Policy with approach to the Urbanistic Right and the right to the housing, the reflections by Raquel Rolnik, Nabil Bonduki, Ermínia Maricato, Saule Júnior, Betânia de Moraes Alfonsin and Edésio Fernandes are main references. To gauge the execution of the objectives proposed by Habitar Brasil in 1993, it has searched in the documentary data of the time and in information gotten in interviews with technicians that had participated of the program, consistent references on what was considered, what was executed and the process of the intervention of Habitar Brasil in the Africa community. The area analysis in 2005-2006 has developed on the base of the urbanistic survey of the current situation from the four performance lines of the Program: habitation, infrastructure, community equipments and agrarian regularization, with a current urbanistic evaluation of Africa considering the intervention carried out in 1993 and 1994. The study points out the context of Brazilian Habitational Policy where the Programa Habitar Brasil was launched, explaining the main principles of the Program. In terms of local, it empahsizes the administrative-political factors that had contributed so that Natal-Rn city has been pioneering in the resources captation of Habitar Brazil (1993). Considering Habitar Brazil in Africa, the work argues and presents the intervention diagnosis and the proposal, developed by Program in 1993 evidencing the local problem of the time. After that, it makes a current reading of the area, identifying in 2006 representative elements of Habitar Brasil (1993-1994) for the Africa community. It identifies significant advances in the constitution of the institucional apparatus of the plaining system of Habitation of Social Interest for the city of Natal and points the fragilities in the implementation of the urban infrastructure actions and above all in the achievement of the objectives of the agrarian regularization

Reutilização de imóveis de interesse patrimonial, voltados para a ahabitação: um estudo de caso na Ribeira-Natal/RN

This work analyzes the reutilization of real estate of patrimonial interest, come back toward habitation. One understands as real estate of patrimonial interest the old ones that present relevant architectural typologies that must be preserved; some buildings that represent characteristic architectural styles of a determined period; some valued real estates for the history of the city (historical, memory and image signification that has of certain places) and buildings with exceptional artistic elements. In short, real estate of patrimonial interest. The place or site to be studied will be the neighborhood of the Ribeira, because is an area that protects a bigger interest for the historic patrimony of the city. The habitation use was thought as a booster element of revitalization processes of degradable historic site, contributing to the preservation of artistic, architectural and historic patrimony, and thus to stimulate the accomplishment of the re-qualification of the neighborhood of the Ribeira. It is intended with the present study to examine alternatives to make possible habitation re (uses) in the historical quarter of the Ribeira in old constructions of patrimonial value

Análises de elementos arquitetônicos de proteção solar em edificações institucionais na cidade de Natal/RN Diretrizes projetuais

The present work concerns the use of shade elements as architectural elements to block sunlight in public buildings. In a city like Natal, (5o South) the incidence of sunrays in any type of design should be a constant concern for all the architects. Besides, this habit of avoiding insolation in the environment is not a common practice. Within this context, the present work has the objective to dig deep into the knowledge of solar control, studying some cases and verifying its function according to the orientation and the original design of the building, having in mind if the shade elements usually used in the region have achieved their purpose of providing protection against the incidence of direct sun rays. This study considers the position of the shade element (horizontal and vertical), the angle formed between them and the respective facades, and the local of the buildings in relation to their orientation during the summer, winter and equinox solstice. As supporting instruments the solar map of the city and the protractor, for measuring shade angles, were used. It was concluded that in all the cases studied, it was not possible to obtain the maximum use of the elements. It was verified that the best type of shade element (more efficient) for the city of Natal is the mixed type (horizontal and vertical) and that the vertical shade elements are more efficient in the early mornings and late afternoon. The horizontal shade elements are used more effective at midday. We intend to present the results of this study to the architects in the region in order to show them the correct ways of using the shade elements according to the possible orientation on the facade, as a supporting tool at the time of designing a project as well as a subsidy for further discussions on the elaboration of the new urban standards for the city of Natal/RN

Avaliação da ecotoxicidade de percolados em áreas de disposição de resíduos na região metropolitana de Natal/RN

Leachates are effluent produced by decomposition of solid waste, they have complex composition and can be highly toxic. Therefore such percolated liquid should be collected and treated properly to avoid environmental contamination of soil and of water bodies. The objective of this study was to evaluate the toxicity through ecotoxicological tests with Ceriodaphnia dubia (Cladocera - Crustacea) of percolated liquids generated in two different systems of municipal solid waste (MSW) disposal in the city of Natal/ RN: A Sanitary Landfill in the Metropolitan Region of Natal/ RN, and in a dump off area. Furthermore, it was evaluated the possible contamination of the underground water of the dump off area. Two monthly samples were taken at four points between the months of May/2009 and January/2010. The Point "A" corresponds to the end of the pond leachate treatment in ASRMN; The Point "B" corresponds to a containment pond at the dump. The Point "C" is an area near one of the cells of the dump off area where the leachate outcrops; The Point "D" stands for an underground water well at the area. The last point, called "E" was sampled only once and corresponds to the slurry produced by temporary accumulation of solid waste in the open area of the dump. The ecotoxicological tests, acute and chronic, followed the ABNT 13373/2005 rules, with some modifications. The samples were characterized by measuring the pH number, the dissolved oxygen (DO), the salinity, BOD5, COD, Cd, Cu, Pb, Cr, Fe, Mg, Ni, and Zn. At Point A, the average number of EC50-48h ranged between 1.0% and 2.77% (v/v), showing a high toxicity of the leachate to C.dubia in all months. To this point, positive correlations were found between the EC50- 48 with precipitation. Negative correlations were found between the EC50- 48h with salinity. At point B there was no response of the acute exposure of organisms to the test samples. At point C the EC50-48h ranged from 17.68% to 35.36% in just two months of the five ones analyzed, not correlated meaning. Point D, the EC50-48h level ranged between 12.31% and 71.27%, showed a negative correlation with, only, precipitation. Although it was observed toxicity of underground water in the Landfill Area, there was no evidence of water contamination by leachate, however, due to the toxic character of this water, additional tests should be conducted to confirm the quality of water that is used for human supply. At point E there was no acute toxicity. These results support the dangers of inappropriate disposal of MSW to water bodies due to the high toxicity of the leachate produced highlighting the necessity of places of safe confinement and a treatment system more effective to it

Incidência e fatores de risco da retinopatia diabética em pacientes do Hospital Universitário Onofre Lopes, Natal-RN

Estudar a incidência e fatores de risco (tempo de doença e presença de hipertensão arterial sistêmica) para retinopatia diabética em 1002 pacientes encaminhados pelo Programa de Diabetes do Hospital Universitário Onofre Lopes no período de 1992 – 1995. Métodos: Estudo retrospectivo de pacientes com diagnóstico de diabetes mellitus encaminhados ao Setor de Retina do Departamento de Oftalmologia pelo Programa de Diabetes do Hospital Universitário e submetido, sob a supervisão do autor, a exame oftalmológico, incluindo medida da acuidade visual corrigida (tabela de Snellen), biomicroscopia do segmento anterior e posterior, tonometria de aplanação e oftalmoscopia binocular indireta sob midríase(tropicamida 1% + fenilefrina 10%). Foi realizada análise dos prontuários referente ao tempo de doenças e diagnostico clínico de hipertensão arterial sistêmica. Resultados: Dos 1002 diabéticos examinados (em 24 deles a fundoscopia foi inviável), 978 foram separados em 4 grupos: sem retinopatia diabética (SRD), 675 casos (69,01%); com retinopatia diabética não proliferativa (RDNP), 207 casos (21,16%); com retinopatia diabética proliferativa (RDP), 70 casos (7,15%); e pacientes já fotocoagulados (JFC), 26 casos (2,65%). Do total, 291 eram do sexo masculino (29%) e 711 do sexo feminino (71%). Os 4 grupos foram ainda avaliados quanto ao sexo, a faixa etária, a acuidade visual, tempo de doença, presença de catarata e hipertensão arterial sistêmica e comparados entre si. Com relação ao tipo de diabetes, 95 eram do tipo I (9,4%), 870 pacientes eram do tipo II (86,8%), e em 37 casos(3,7%) o tipo de diabetes não foi determinado. Conclusões: Comprovou-se que os pacientes com maior tempo de doença tinham maior probabilidade de desenvolver retinopatia diabética, e que a hipertensão arterial sistêmica não constituiu fator de risco em relação à diminuição da acuidade visual nos pacientes hipertensos

Os comportamentos de alguns adolescentes estudados indicam um estilo de vida saudável, enquanto outros demonstram justamente o contrário, através de práticas como: pouca participação no lazer, por falta de opção; consumo de drogas lícitas e ilícitas; a falta de diálogo com os pais sobre sexo; relacionamento sexual precoce, somados às condições econômicas e sociais desfavorecidas que os expõem à adoção de um estilo de vida que implica em vulnerabilidade

O uso do móbile marketing como estratégia de fidelização de clientes :um estudo e empresas do setor de comércio e serviços em natal-RN

This study aims to understand the effects of the mobile marketing use as a relationships tool for companies that operate locally, because of the lack of information about this new marketing tool, as well as the scarcity of studies in this area. This is an exploratory and qualitatively study, based on primary sources, raised through books, articles in the marketing area and the telecommunications industry organs as well as secondary sources. With the purpose to look into the issue, a semi-structured interview is made with the companies managers of the sectors of trade and services in Natal-RN. The advances in technology allow an important discussion focused on the marketing in the new communication technologies scenario. It appears that the mobile marketing adoption and use by local companies is already a reality and companies are awake to changes and technological innovations accessible, especially the mobile telephony as well as convergence with other media. There is, however, that the use of technologies offered by mobile marketing is still limited to the sending of text messages (SMS), despite the numerous possibilities of it use. Moreover, the results obtained with mobile marketing use show that companies can identify them, but there is no effective monitoring in quantity and financial terms. Only affect sales growth and support for progress in loyalty with customers. It shows up that the mentality of not measuring the results still in the plan of changes and technological innovations. The data allow saying that the mobile marketing is a reality, however has not yet signed as a tool for carrying out campaigns and marketing tool for loyalty of customers, despite presenting a wide range of possibilities to streamline and make more effective the marketing businesses process

Diagnóstico da cultura organizacional em hospitais da rede privada de Natal/RN

As peculiaridades presentes no ser humano são observadas a partir da manifestação de sua cultura. Estas manifestações podem ser influenciadas pelo contexto social do indivíduo. A cultura nacional é uma destas influências. A brasileira, por exemplo, possui alguns traços nacionais peculiares ao seu povo que amenizam a sua complexidade e pluralidade. Estes traços podem se tornar influentes na cultura organizacional, através da manifestação das práticas e dos valores utilizados pela organização. Diante disso, o presente trabalho teve como objetivo diagnosticar a cultura organizacional dos hospitais, enfatizando as práticas e os valores organizacionais e a percepção dos colaboradores sobre a cultura organizacional. A metodologia utilizada na pesquisa foi de caráter descritivo e explicativo. A pesquisa ocorreu através da aplicação do Instrumento Brasileiro para a Avaliação da Cultura Organizacional IBACO, com 283 sujeitos distribuídos em três hospitais da rede privada de Natal/RN. As evidências encontradas pelo estudo foram analisadas através do software estatístico SPSS, com as técnicas multivariadas de análise fatorial, análise de aglomerados e análise discriminante. A partir dessas análises, foram obtidos cinco fatores distribuídos entre práticas e valores apresentados pelo IBACO, que foram: as práticas de recompensa e treinamento; integração externa e promoção do relacionamento interpessoal; e, os valores de satisfação, bem-estar e cooperação dos empregados e profissionalismo competitivo. Os grupos encontrados na análise apresentaram divergências de opinião quanto às práticas e os valores utilizados nos hospitais. Concluiu-se, portanto, que o Hospital A apresentou uma cultura mais proativa e voltada mais para a satisfação e bem-estar dos funcionários. Já os outros dois hospitais apresentaram culturas semelhantes, com limitações quanto à valorização do bem-estar e da cooperação entre os colaboradores, porém com uma boa prática do relacionamento interpessoal

Síndrome de Burnout e autoeficácia: um estudo com profissionais de enfermagem de hospitais privados de Natal/RN

This research verifies the influence of the self-efficacy level on burnout syndrome incidence in relation to nursing professionals from private hospitals located in the Municipality of Natal, State of Rio Grande do Norte. The nature of the research was descriptive, and the used data analysis method was quantitative which was developed through SPSS computational package, version 17.0. The used instrument for the investigation was Maslach-Burnout Inventory (MBI), and the General Perceived Self-efficacy Scale (GPSES) was applied to a sample formed from 230 nursing professionals. The statistic techniques to data analysis were: frequency analysis; factor analysis; Cronbach.s alpha; Kaiser-Meyer-Olkin test (KMO); Bartlett efericity test; percentual analysis; Spearman rank correlation analysis; and simple regression. The achieved factors from factor analysis of MBI were the same, taking into account the dimensions which Maslach initially suggested to the instrument (emotional exhaustion, lack of personal realization, and depersonalization). However, one highlights that the low internal consistence of the depersonalization dimension can occur from people.s difficulty (caused by cultural aspects) of assuming this attitude in their work environment. Through GSE, it was achieved a factor which confirmed the unidimensionality showed by the author of the instrument. In relation to the syndrome incidence, it was verified that about 50% of the researched sample presented burnout syndrome evidence. Referring to self-efficacy level, about 65% of the researched sample presented low level of self-efficacy, what can be explained by the work characteristics of these professionals. In relation to the self-efficacy influence on the Burnout syndrome, it was verified that self-efficacy can be one of the aspects which influences occupational stress chronification (burnout), mainly to the personal realization dimension. Therefore, the researched hospital organizations need reflect about their attitudes in respect to their professionals, since the numbers showed a dangerous tendency regarding a predisposition to burnout syndrome of their staff, what implies not only a significant amount of individuals who can present high levels of emotional exhaustion, lack of personal realization, and depersonalization, but also the fact that this group presents low level of self-efficacy

Racionalidade substantiva no processo decisório: um estudo em instituições que lidam com o tratamento oncológico infantojuvenil na cidade de Natal-RN

The present study regards an applied social research (qualitative) performed in two institutions which lead children s cancer treatment in Natal, Rio Grande do Norte. The main goal of this study is, as of a literature review at works which characterizes the first generations of study about substantive rationality, to detect Decision Making process related aspects that may serve as a basis to elaborate analysis categories from decision making process, aggregating them into a new study that may provide an advance to the theme in administrative science. The academic works based on the analysis model created by Mauricio Serva served as a basis to deep research into such theme, which verifies the predominant rationality in eleven administrative internal processes in productive organizations. This dissertation intends to go beyond the identification of the predominant rationality by elaborating new categories of analysis, and making possible the continuity of the subject in administrative science. Based on Guerreiro Ramos s work, which sees a kind of ideal organization, as known as isonomies, this study still calls upon Karl Polanyi s thoughts, which with the objective of comprehending the independent economic phenomenon of the value that allows considering non-market economies, find that the economy of the men is submerged in his social relations; it also rescues the studies from Max Weber who investigates the meaning of social action to better understand the rationality, and refers to the study of Jürgen Habermas, who proposes a broader conception about rationality, within the theory of communicative action. As a result of this theme s review, seven analysis categories of the decision making process have been formulated. They were applied in the institutions that had been chosen and helped to detect the type of predominant rationality in the categories of the decision making process. The results confirm that, although the decisions making process involves rational elements, such as information, identification of alternatives, there are also specific values of each individual with his experience and view oh the world, permeated not only by instrumental rationality, but also by substantive rationality. The study has verified that two similar institutions may show different types of rationality in the decision making process, when decision factors may tend to instrumental rationality, according to administration classic way, as well as they may emerge from substantive rationality, thus contributing to the process of emancipation of the human being in his sphere of work

Política pública e educação digital no ensino fundamental em Natal/RN: análise de eficácia da atuação dos objetivos do Proinfo Municipal
