Qualidade do ar interior e conforto térmico : um estudo em espaços de estacionamento em Natal/RN

The recent tendency to utilize parking lots for other purposes has demonstrated that more time has been spent by visitors, mainly in great cities. Therefore, this paper investigates the thermal comfort and the air quality indoors in areas specifically used as parking lots by analyzing the direct relation between such environments and vehicular pollution. The thermal comfort and the quality of air indoors in parking lots with different architectonic typology (ground-floor and underground) are also studied, aiming to contribute to the proposition of suitable new areas designated to human usage. Field research was done, in two distinct periods within different weather conditions (January and July) in, two naturally cooled, parking lots located in Natal - RN. The internal environment agents were measured by using tools for air temperature, humidity, speed and direction; interviews with employees and visitors and chemical analysis through appropriate tools to analyze specific material, carbon monoxide and ozone. The results showed that chemical agents densely concentrate mostly in the closed parking space, aggravated by weather conditions, which dissatisfied the visitors. Still, it was shown that architectonic typology, alongside topographical aspects compromise internal environmental conditions, which increases the retention of pollution, leading to dissatisfactory thermal comfort levels and becoming less suitable for usage by visitors considering air and thermal comfort aspects. Consequently, they are not suitable for human stay due to the poor quality of the indoor air

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

Percepção ambiental do patrimônio cultural: estudo de caso na Cidade Alta e Ribeira em Natal-RN

Contemporary studies have shown that the evolution of the heritage concepts is accompanied by an affirmation of the importance of social participation in recognizing heritage values and in managing cultural assets. We used the Brazilian context to emphasize the challenges for democratizing this process. This problematic is discussed based on the cases of Cidade Altaand Ribeira, neighborhoods that date from the formation of Natal-RNand have cultural assets recognized by levels of government. The study builds elements to answer the research question: what meanings and representations does the culturalheritage in the case study have for its users? The research method analyzes the representations and the meanings of the neighborhoods, firstly is based on historiographical studies, memories records of the city and on the process of heritage management. Secondly, it isbased on the field research, it is structured in environmental perception studies (areas of Environmental Psychology, Architecture and Urbanism) and has been applied with users with different bonds with the studied environment (residents, workers and visitors). The data were obtained with the multi-method which included direct observation, questionnaire survey and mentalmaps (that replicate Kevin Lynch). The analysis of result verified the research hypothesis, emphasizing aspects of the relationship between users and cultural heritage relevant to strengthening collective memory, local identity, contributing to heritage management. Among the results, the socio-environmental image obtained which emphasized a "cultural axis" linkingboth studied neighborhoods and confirms the influences of elements rein the memories records of the city and in the area s management. Identified aspects to strengthen the relationship between the users and cultural assets, such as the presence of placeswith affective ties to certain groups, as well as the need to fight off negative images (of degradation and insecurity) associated to the site and also expand the participation of the population, including residents, in policies and cultural activities. After all, recognition of value and the involvement of societycultural assets have the potential of contribute to integrate city development with heritage conservation

Influência de variáveis arquitetônicas no desempenho energético de hotéis no clima quente e úmido da cidade de Natal/RN

This master thesis aims to assess the influence of the design decisions on the energy building performance of hotels. The research is based on the integration of field study and computer simulation. Firstly, a detailed field study is carried out to identify the characteristics of hotels in Natal, Rio Grande do Norte. The items assessed are occupancies, light and equipment densities, types of air conditioning, total and monthly energy consumption, among others. A second and more comprehensive field study is carried out to identify the range of occurrence of architectural variables, with a larger number of buildings. A base case is modelled in VisualDOE, based on the first field study. Then, a first set of simulations are run to explore the sensitivity of the variables on the energy consumption. The results analyses were the base of a second set of simulations, which combined the most influential variables. The results of 384 models were assessed, and the impacts of design decisions were quantified. The study discusses tendencies and recommendations, as well as the methods advantages and disadvantages

Estádios larvais e ocorrência saxonal de imaturos de Psaroniocompsa incrustata (Lutz,1910)(Diptera:Smimuliidae) no Rio Pium, município de Nísia Floesta, RN

The larval instars, seasonal occurrence and environmental factors influence on Psaroniocompsa incrustata (Lutz, 1910) (Diptera: Simuliidae) immature were studied according to its physical and chemical aspects of breeding water. Four collects were made at vegetal substrate from margin, middle and floating on the Pium river, city of Nísia Floresta, state of Rio Grande do Norte, Brazil at dry and wet season. Some of larval characters were used to determinate the larval instars number like lateral length of cephalic capsulae, antennae and the distance among cephalic apodema, as well as pH, water temperature, width, depth, stream velocity, discharge and pluviometric precipitation were used for physical factors. Seven larval instars were determined for this P. incrustata community being the lateral length of cephalic capsulae as the best structure with this meaning propose. The seasonality immature abundance of this species were found in dry season and a positive correlation with pH, stream velocity and precipitation

Caracterização ambiental de bancos areno-lamosos nos campos petrolíferos de Macau e Serra (RN), como subsídio às medidas mitigadoras ao processo erosivo

On Rio Grande do Norte northern coast the process of sediment transport are intensely controlled by wind and sea (waves and currents) action, causing erosion and shoreline morphological instability. Due to the importance of such coastal zone it was realized the multi-spectral mapping and physical-chemical characterization of mudflats and mangroves aiming to support the mitigating actions related to the containment of the erosive process on the oil fields of Macau and Serra installed at the study area. The multi-spectral bands of 2000 and 2008 LANDSAT 5 TM images were submitted on the several digital processing steps and RGB color compositions integrating spectral bands and Principal Components. Such processing methodology was important to the mapping of different units on surface, together with field works. It was possible to make an analogy of the spectral characteristics of wetlands with vegetations areas (mangrove), showing the possibility to make a restoration of this area, contributing with the environmental monitoring of that ecosystem. The maps of several units were integrated in GIS environment at 1:60,000 scale, including the classification of features according to the presence or absence of vegetation cover. Thus, the strategy of methodology established that there are 10.13 km2 at least of sandy-muddy and of these approximately 0.89 km2 with the possibility to be used in a reforestation of typical flora of mangrove. The physical-chemical characterization showed areas with potential to introduce local species of mangrove and they had a pH above neutral with a mean of 8.4. The characteristic particle size is sand in the fine fractions, the high levels of carbonate, organic matter and major and trace element in general are concentrated where the sediment had the less particles size, showing the high correlation that those elements have with smaller particles of sediment. The application of that methodological strategy is relevant to the better understanding of features behavior and physical-chemical data of sediment samples collected on field allow the analysis of efficiency/capability of sandy-muddy to reforestation with local mangrove species for mitigation of the erosive action and coastal processes on the areas occupied by the oil industry

Avaliação ambiental de manguezais adjacentes aos campos petrolíferos de Macau e Serra (RN), como subsídio às medidas mitigadoras ao processo erosivo

Among the various effects caused by the climate change and human intervention, the mangrove ecosystem changes through of the years has been worth mentioning, which hasn t known which are the pros and cons for the adjacent coastal and estuarine environments yet. It happens due to the present dynamism in these areas, besides of the difficult understanding of the processes associated with evolution. This study aimed to environmentally evaluate adjacent mangroves from the Macau and Serra oil fields, located on Rio Grande do Norte northern coast, to support the mitigating actions related to the containment of the erosive process, as well as, according to the principles of the Clean Development Mechanism (CDM), to assess the amount of atmospheric carbon sequestered by the studied ecosystem. An inventory was conducted through mangrouve mapping which has supplied this research, especially regarding to the structural characterization of mangrove areas. To understand the local mangrove behavior in a greater level detail, techniques of remote sensing, GIS and GPS were used to make an analogy between the current and past states of the mangrove studied, allowing to make anticipated projections for the future impacts or changes in that region. This study combined data from multispectral LANDSAT 5 TM, Landsat 7 ETM+ with radar microwave data from SAR RADARSAT-1, which increased the interpretation capacity of the data from optical sensor systems. The interpretations have been supported by the data field, representing a better and innovative methodology for the environmental and taxonomic characterization of mangrove forests considered. The results reveal that mangroves of the Ponta do Tubarão Sustainable Development Reserve are biologically representative areas and providing a variety of benefits, especially for local communities, constituting the priority sites for actions development aimed at conservation. They also have been showing the necessity to make mitigating measures in order to recover degraded areas through reforestation or creating new areas of mangrove, as currently 7.1% of the mangrove forests studied are dead or in an advanced state of decomposition. The amount of atmospheric carbon sequestered proved very significant when analyzed for the whole area, which is able to sequester atmospheric 4,294,458 Ton CO2 per year

Design gráfico da pluma de contaminação por compostos orgânicos voláteiss utilizando software CAD na investigação de passivo ambiental em um posto revendedor de combustíveis em Natal/RN

Among the potentially polluting economic activities that compromise the quality of groundwater are the gas stations. The city of Natal has about 120 gas stations, of which only has an environmental license for operation. Discontinuities in the offices were notified by the Public Ministry of Rio Grande do Norte to carry out the environmental adaptations, among which is the investigation of environmental liabilities. The preliminary and confirmatory stages of this investigation consisted in the evaluation of soil gas surveys with two confirmatory chemical analysis of BTEX, PAH and TPH. To get a good evaluation and interpretation of results obtained in the field, it became necessary three-dimensional representation of them. We used a CAD software to graph the equipment installed in a retail service station fuel in Natal, as well as the plumes of contamination by volatile organic compounds. The tool was concluded that contamination is not located in the current system of underground storage of fuel development, but reflects the historical past in which tanks were removed not tight gasoline and diesel

Caracterização fenotípica e genotípica de Staphylococcus aureus resistentes à meticilina isolados na cidade do Natal/RN

Staphylococcus aureus resistente à meticilina (MRSA) é um dos principais agentes de infecções associadas a serviços de saúde em todo o mundo. No Brasil, há a predominância de um clone de MRSA multirresistente denominando clone epidêmico brasileiro (CEB). Entretanto, novos clones nãomultirresistentes com alta virulência têm sido descritos em infecções comunitárias e hospitalares. O objetivo desse estudo foi realizar a caracterização fenotípica e genotípica de cepas de MRSA isoladas na cidade do Natal/RN. Inicialmente avaliamos 60 amostras de S. aureus quanto a resistência à meticilina através de diferentes técnicas fenotípicas, utilizando a detecção do gene mecA por PCR como padrão. O antibiograma de todas as cepas foi realizado utilizando 12 antimicrobianos conforme descrito pelo CLSI. As cepas de MRSA foram caracterizadas geneticamente através da tipagem do cassete cromossômico estafilocócico mec (SCCmec) e da eletroforese em campo elétrico alternado (PFGE). Dos 60 S. aureus estudados, 45 foram resistentes à meticilina. Observamos que para algumas cepas de MRSA os testes de triagem em ágar com 6μg/mL de oxacilina e difusão em meio sólido com oxacilina-1μg apresentaram dificuldades na sua interpretação. No entanto, todas as 45 amostras de MRSA, foram facilmente detectadas pelos testes com o disco de cefoxitina-30μg e pesquisa da PBP2a. A análise molecular das cepas de MRSA mostrou 8 padrões distintos de PFGE (A-H), com predominância do padrão A (73%), relacionado ao CEB. Estas carreavam o SCCmec tipo IIIA, e apresentaram uma considerável variedade de subtipos (A1-A16). Cinco cepas de MRSA portando SCCmec IV também foram xiv identificadas, três delas relacionadas geneticamente ao clone USA800 (Padrão B). Destas cinco, três (2 padrão F e 1 padrão B) foram altamente susceptíveis as drogas testadas, entretanto, dois outros isolados, padrão B, apresentaram multirresistência. As amostras restantes pertenciam a padrões de PFGE distintos dos clones internacionais predominantes em nosso continente. Para realização deste projeto de pesquisa, a metodologia exigiu a interação com pesquisadores de áreas como: infectologia, microbiologia e biologia molecular. Portanto, esta dissertação apresentou um caráter de multidisciplinaridade e transdiciplinaridade no seu desenvolvimento

Associativismo nos municípios rurais: uma alternativa de desenvolvimento local em Portalegre/RN

This work aims to study the associations as mediating the process of social change and its importance for local development. The hypothesis is that associations, but bring dynamism to the smaller cities and improve the living conditions of their members, relegated to the background social sustainability, understood this as a permanent exercise of mobilization and participation in community life. The assumptions of the study are that the practice group has influenced the processes of local development in Brazilian rural municipalities through the mediation of government programs and projects aimed at combating rural poverty require social organization for their achievement. The concept of local development in this work was rescued from studies of political economy and sociology. But the concepts of collective action and partnerships advêem studies of political participation and social development of the theory of alternative or solidarity. The party consisted of an empirical case study conducted with four associations of farmers in the municipality of Portalegre-RN. Why choose qualitative study was used the technique of semi-structured interviews with the chairmen I members of associations and other actors considered essential to understanding the study (religious leaders, local political power and chairman of the union of rural workers), a total of 20 interviews, in addition to the observations of field and documentary research in records of the.ir own organizations. The survey results show that the performance of groups of farmers are key components and determinants for the production I marketing of agricultural products and for boosting the economy, as well as security for minimum levels of citizenship. Yet we are still in a space purpose of social change, which comes to confirm the initial hypothesis of this work

Implementação da política de assistência social em Mossoró/RN : uma avaliação a partir dos centros de referência da assistência social

The current National Policy for Social Assistance (PNAS) is the instrument that regulates the organization and procedures of social-welfare actions. Developed and approved in 2004 since the Unified Social Assistance System (ITS) was crated in 2003, it reaffirms the democratic principles of the Social Assistance Organic Law (LOAS) focusing on the universalization of social rights and equality of rights when accessing the social-welfare system. In the SUAS point of view, the PNAS highlights the information, monitoring and evaluation fields for being the best way to assure the regulation, organization and control by the Federal Government paying attention to the principles of decentralization and participation. This political-institutional rearrangement occurs through the pact among all the three federal entities. The pact deals with the implementation of the task. It says that it has to be shared between the federal autonomous entities, established by dividing responsibilities. To the cities, considered as the smallest territorial unit of the federation and closer to the population, was given the primary responsibility, which is to feed and maintain the database of SUAS NETWORK and identify families living in situations of social vulnerability. In addition to these responsibilities, the cities that have full autonomy in the management of their actions, have the responsibility to organize the basic social protection and the special social protection, that using the Center of Social Assistance Reference (CRAS) and the Center of Specialized Social Assistance Reference (CREAS), are responsible for the provision of programs, projects and services that strengthen the family and community; that promote people who are able to enjoy the benefits of the Continuing benefit of Provisions (BPC) and transfer of incomes; that hold the infringed rights on its territory; that maximize the protective role of families and strengthen its users organization. In Mossoró/RN, city classified as autonomous in the social assistance management, has five units of CRAS that, for being public utilities, are considered the main units of basic social protection, since they are responsible for the connection between the other institutions that compose the network of local social protection. Also known as Family House, the CRAS, among other programs and services, offers the Integral Attention to Families Program (PAIF), Juvenile ProJovem Program, socio-educational coexistence services programs, as well as sending people to other public policies and social-welfare services network, provides information, among others. In this large field, social workers are highlighted as keys to implement the policy of social assistance within the city, followed by psychologists and educators. They should be effective public employees, as a solution to ensure that the provision of the services are to be continued, provided to the population living around the units. However, what we can find here is inattention to the standard rules of social assistance, which not only undermines the quality of programs and services, but also the consolidation of policy on welfare as public policy of social rights

A Cabana Umbamdista Pai Joaquim de Angola: frente a intolerância a Umbanda na Cidade do Natal/RN

This dissertation presents an attempt to register the initial steps of african-Brazilian religion Umbanda in the city of Natal, capital of Rio Grande do Norte, from a case study of Cabana Umbanda Pai Joaquim de Angola, represented by its maintainer, umbanda of the priest José Clementino. The main objective is to record the memories of fans in aspects of its tradition, experience social and cultural religious building, in an attempt to show the religious hatred with practitioners of Umbanda. Used to: in audio recordings of festivals and rituals, narratives about the memories and stories of employees and their explanations, photographs, diary entries in the field, participant observation and interviews available. The analysis referred to in umbanda Natal / RN, was based on field research as a product of the visits that took place between the years 2006 to 2009 in Terreiro de Umbanda Pai Joaquim de Angola, located in the neighborhood of Rocas.

Jovens assentados, jovens estudantes, jovens professores: juventude em assentamentos rurais do RN

This work discusses how schooling processes can contribute to young settlers resignify their relationship with rural settlements where they live. We want to understand youngster s place, his relationship with local community, social movements and their acting, after formation, at their localities. Thereunto, we tracked a group of students of Land Teaching Course, developed through a partnership between UFRN, INCRA and MST in the years 2004 to 2007. We observed their trajectories, the learnings provided by the Course and how Formation Centre experiences contributed to their agent conditions, offering them choice opportunities on different fields. We understand that formation process enabled them to have individual gains, widening their range of choices, while have contributed to development of areas in which they live, from their collective action. Social practices experienced in collective environment, combined with education access, provided a set of knowledge. These learnings have enabled youngsters to assume positions in participation areas which have been opened at school, while teachers, at social movements and at associations that manage the settlements

Entre desvios e normas: infração juvenil feminina na cidade de Natal - RN

This paper presents some reflections on the social world of young female transgression. The context corresponds to those ones that obey social and educational measures in The Padre João Maria Education Centre (CEDUC), in Natal- RN. This behavior, according to the Statute of Children and Young (ECA, 1990), is defined as "conduct described as crime or misdemeanor." Our goal is to discuss aspects of the contexts in which young women are interacting with the universe of total institutional control mechanisms. Through the socio-anthropological analysis of the ethnographic practice in field research, it was necessary to question the concept of misuse engaged in the practice of penalties awarded to young women in the context of private freedom. So was built a frame relating the representations of the relations of gender, generation, the practice of violence and crime from the look on CEDUC/ Padre João Maria Education Centre

Política cultural no RN: uma avaliação das casas de cultura popular (2003/2010)

The issue of public policy for the culture area has experienced a significant increase of interest of academic researchers. The research "Cultural Policy in infants: an evaluation of the home culture (2003/2010)" aimed to evaluate the effectiveness of cultural policy in Rio Grande do Norte in the period 2003/2010. When was the program created and deployed the houses of popular culture. Specifically, he sought: a) mapping the major elements of cultural policy in the RN during the chronological period mentioned b) hold up in more detail in the description of the implementation process of the houses of popular culture, c) investigate cultural actions implemented by the houses of popular culture and its effectiveness. The methodological process consisted of a review of the literature on culture, cultural policy, public policy and public policy evaluation for the construction of the theoretical-analytical, documentary research in public and private institutions related cultural production; interview with managers and cultural producers in visits field research conducted in seven major houses of popular culture, taken as a sample of the total d 29 outlets installed during the chronological period mentioned. The survey found that the program houses RN popular culture in general was effective in meeting its objectives, among which the decentralization of cultural inclusion in the artist market cultural production, the promotion of folk traditions in the region , respect and support for new artists, respect and support for popular memory
