OBJETIVO: avaliar a sintomatologia climatérica e fatores relacionados entre mulheres dos meios urbano e rural do Rio Grande do Norte. MÉTODOS: estudo transversal, descritivo, envolvendo casuística de 261 mulheres climatéricas residentes em Natal e Mossoró (grupo urbano; n=130) e Uruaçu, em São Gonçalo do Amarante (grupo rural; n=131). A sintomatologia climatérica foi avaliada pelo Índice Menopausal de Blatt-Kupperman (IMBK) e Escala Climatérica de Greene (ECG). A análise estatística constou de comparações das medianas dos escores entre os grupos e regressão logística. Defi niram-se como “muito sintomáticas” as pacientes com escores ≥20, para ambos instrumentos (variável dependente). As variáveis independentes foram: idade, procedência, alfabetização, obesidade e prática de atividade física. RESULTADOS: o grupo urbano apresentou escores signifi cativamente superiores ao grupo rural, tanto para o IMBK (medianas de 26,0 e 17,0, respectivamente; p<0,0001), quanto para a ECG (medianas de 27,0 e 16,0, respectivamente; p<0,0001). Na amostra total, evidenciou-se que 56,3% (n=147) das mulheres foram classifi cadas como “muito sintomáticas”. Na comparação intergrupos, essa prevalência foi signifi cativamente mais elevada nas mulheres urbanas em relação às rurais (79,2 e 33,6%, respectivamente; p<0,05). Pela análise de regressão logística, evidenciou-se que a chance de pertencer ao grupo defi nido como “muito sintomáticas” foi maior para mulheres do meio urbano [odds ratio ajustado (OR)=7,1; 95% intervalo de confi ança a 95% (IC95%)=3,69-13,66] e alfabetizadas (OR=2,19; IC95%=1,16-4,13). A idade superior a 60 anos associou-se com menor chance de ocorrência de sintomas signifi cativos (OR=0,38; IC95%=0,17-0,87). CONCLUSÕES: a prevalência de sintomas climatéricos signifi cativos é menor em mulheres do meio rural, demonstrando que fatores socioculturais e ambientais estão fortemente relacionados ao surgimento dos sintomas climatéricos em nossa população.___________________________________ABSTRACT PURPOSE: to evaluate climacteric symptoms and related factors in women living in rural and urban areas of Rio Grande do Norte, Brazil. METHODS: a cross-sectional study involving 261 women in the climacteric was performed. A total of 130 women from Natal and Mossoró (urban group) and 131 from Uruaçu, in São Gonçalo do Amarante (rural group), were studied. Climacteric symptoms were assessed by the Blatt-Kupperman Menopausal Index (BKMI) and Greene Climacteric Scale (GCE). Statistical analysis involved comparison of median between groups and logistic regression analysis. Patients were defi ned as “very symptomatic” when the climacteric score was ≥20 for both questionnaires (dependent variable). Independent variables were: age, living area, schooling, obesity and physical activity. RESULTS: the urban group had signifi cantly higher scores than those of the rural group, both for BKMI (median of 26.0 and 17.0, respectively; p<0.0001) and for GCE (median of 27.0 and 16.0, respectively; p<0.0001). For the entire sample, a total of 56.3% (n=147) of the women were classifi ed as “very symptomatic”. This prevalence was signifi cantly higher in urban than in rural women (79.2 and 33.6%, respectively; p<0.05). Logistic regression analysis showed that the likelihood of belonging to the group defi ned as “very symptomatic” was greater for urban women [adjusted odds ratio (OR)=7.1; confi dence interval at 95% (95%CI)=3.69-13.66] who were literate (OR=2.19; 95%CI=1.16- 4.13). Individuals over the age of 60 years had less chance of having signifi cant symptoms (OR=0.38; 95%CI=0.17-0.87). CONCLUSIONS: the prevalence of signifi cant climacteric symptoms is less in women from a rural environment, showing that sociocultural and environmental factors are strongly related to the appearance of climacteric symptoms in our population

This research investigates how functionality, rationality, and emotionality applied to urban furniture design contribute to the organization, legibility, and qualification of public spaces, according to different layouts, physical and visual qualities of the urban furniture as well as the quality of urban infrastructure that may influence the uses and appropriation of urban spaces by pedestrians, turning those spaces into socially centripetal or centrifugal places. The work consists of two parts. First refers to a bibliographical review concerning two main issues of the investigation: product design and legibility of public space, defining the conceptual and theoretical bases, linked to methodological strategies aimed at systemic planning and integrated management of urban furniture design and legibility of public spaces (sidewalks), that are necessary to define the existing relationships among the user s interface (pedestrians); product (urban artifacts); built environment (sidewalks). The second part refers to the achievement of empirical approach throughout visual analysis of public spaces and the functional and qualitative evaluation of the existing urban furniture in the central neighborhood of Cidade Alta, Natal, RN, according to the theoretical researched concepts and methodological procedures. The results expose the weaknesses and levels of intensity arising from the relations among public space, urban furniture, and users, revealing the need for theoretical and practical approaches which would help the decision-making in planning, designing and integrating innovative, sustainable, and ethical solutions in order to design attractive public spaces that could provide sociability and citizenship throughout integrated public management, city systemic thinking and urban identity. The suggested guidelines at the end of this research will provide the necessary strategies to design suitable urban furniture systems according to aesthetic and practical urban infrastructure and city context, aiming to ease visual and physical conflicts that may negatively interfere with the appropriation of public spaces by the citizens

Both the end of the twentieth century and the beginning of the twenty-first century have been characterized as a period of major political, economic, social and cultural transformations. Two of the major consequences of the political-economical crisis of the end of last century are the restructuring of capitalist production, and the consolidation of neoliberalism as a worldwide phenomenon. This new world political-economical scenario has influenced, in a dialectic way, the contemporary urban development. In that sense, "new" spatial processes and new paradigms in both urban management and urban planning have gained shape. In this context of urban transformations, the central areas of western cities, also known as historic centers, are being increasingly (re)valued. Since the Second World War, the historic centers urban areas which have great infrastructure and symbolic relevance had been undergoing a process of evasion of population and activities, undeniably linked to the neglect of government authorities. However, in recent decades, the question of historic centers rehabilitation has acquired a growing interest, academically and in political agendas. The object of this dissertation is to focus on how the government of each Brazil and Portugal has dealt with the issue of historic center rehabilitation through programs of urban rehabilitation

The Noise Pollution causes degradation in the quality of the environment and presents itself as one of the most common environmental problems in the big cities. An Urban environment present scenario and their complex acoustic study need to consider the contribution of various noise sources. Accordingly to computational models through mapping and prediction of acoustic scene become important, because they enable the realization of calculations, analyzes and reports, allowing the interpretation of satisfactory results. The study neighborhood is the neighborhood of Lagoa Nova, a central area of the city of Natal, which will undergo major changes in urban space due to urban mobility projects planned for the area around the stadium and the consequent changes of urban form and traffic. Thus, this study aims to evaluate the noise impact caused by road and morphological changes around the stadium Arena das Dunas in the neighborhood of Lagoa Nova, through on-site measurements and mapping using the computational model SoundPLAN year 2012 and the scenario evolution acoustic for the year 2017. For this analysis was the construction of the first acoustic mapping based on current diagnostic acoustic neighborhood, physical mapping, classified vehicle count and measurement of sound pressure level, and to build the prediction of noise were observed for the area study the modifications provided for traffic, urban form and mobility work. In this study, it is concluded that the sound pressure levels of the year in 2012 and 2017 extrapolate current legislation. For the prediction of noise were numerous changes in the acoustic scene, in which the works of urban mobility provided will improve traffic flow, thus reduce the sound pressure level where interventions are expected

The present work analyzes the fast evolution of gated communities in Natal-RN´s urban space. Characterized by the occupation of large areas, providing private security and utilities, this kind of real estate use arises a long list of questions and issues from society and scholars, due to privatization of urban space, bending of law constraints and the lack of an integrated planning of the cities where they are built. The reasons for its fast growth in Brazil s urban areas are analyzed, considering the impact on formal urban planning and municipal services and on the identification of urbanistic, architectural pattern and constraints, as well as legal, social and economic issues. This study is based on the detailed analysis of the first three units of gated communities built in the urban space in Natal, between 1995 and 2003, including their evolution throughout time and the specific social and economic reasons for its present widespread adoption in Brazilian real estate market and, particulary, in our city. The main objective of this piece of work is to answer the why s and how s these phenomena evolved, setting a basis for the definition of adequate public policies and regulation of this kind of urban land use

The present study deals with the relationship between urban vegetation and climate. The process whereby the Parque das Dunas a 1,172 ha green area in the city of Natal, State of Rio Grande do Norte exerts influence on the climate of the city is analyzed. The hypothesis on which the present work rests is that the green area referred to acts upon the climate of the city. The study is based on the analysis of climatic factors and elements of this green area and of the city of Natal. In order to give rise to final recommendations, a methodology grounded on a quantitative and qualitative standpoint has been used. The data were collected both within and without the limits of the Parque das Dunas area. Secondary and primary data resulting from the measurements taken by the researcher and her work group have been used. The aim was to contribute to the understanding of the influence of vegetation on the climate of a city having a warm and humid climate. A historical and environmental characterization of the Parque das Dunas was then sought. The local climatic factors and the elements of the climate have been studied within the scope of the city of Natal. A comparative study between the climatic elements within and without the limits of the Parque das Dunas area from the survey of technical data and the systematization of the information collected has been made, aiming at proposing a set of bioclimatic recommendations for the urban design in Natal. The results of such work allowed for the validation of the important role that the Parque das Dunas plays in the climate of Natal. This has led to the acknowledgement of the relevance of the green areas on the climate of cities. They bring about important benefits to the process of rendering agreeable the climate in the urban environment by providing pleasant microclimates that give a valuable contribution to the environmental comfort of urban nuclei having the same size of Natal

This work aims to analyze and evaluate the Urban furniture designed to public areas according to the Revitalization planning for Rio Grande do Norte coastland, defining visual relations among urban elements in the landscape of revitalized public urban areas with cultural, paisagistic and touristic values and the design process used for developing urban furniture to those areas, observing the incoming consequences use to that process in a specific urban context which alters use, functions, cultural images as well as social values attributed to each particular place. Environmental perceptions, legibility of local cultural references and their representation through the design of urban elements, act in a positive or negative manner over the inhabitants cognition process of some particular revitalized area, determining new use and attributions to those areas. Designs for coastal urban interventions try excessively to standardize technical media, construction materials and planning configurations, creating artificial sceneries that segregates users, imposing new structures and usage, generating, consequently, the so called non-places and burlesque regionalism. The research is divided into 4 chapters: 1) Theoretical support (Industrial design; Urban furniture; Public urban spaces; Urban image and environmental perception; Urban occupation and interventions in coastland areas); 2) Methodological procedures and data collection; 3) Analysis of Rio Grande do Norte coastal areas and their urban interventions; 4) Final considerations and Industrial Design contributions to the subject

Os seres humanos ao se reproduzirem como espécie e ao produzirem seus bens materiais produzem o espaço geográfico. Historicamente, o espaço vem sendo produzido em função do processo produtivo geral da sociedade. Partindo dessa abordagem, o trabalho em foco destina-se a fazer a análise da produção do traçado urbano de um simples povoado do litoral norte-rio-grandense, denominado Cajueiro, no qual observa-se uma total despreocupação com a composição urbanística da área, pelo fato da sua construção seguir os caminhos naturais vivenciados pelos seus moradores, mediante o atendimento das suas necessidades de sobrevivência ao longo dos anos. Para melhor entender historicamente a produção desse espaço litorâneo, optou-se por caminhar pelas suas ruas, becos e veredas, buscando através de entrevistas dirigidas e "bate papos espontâneos", explicações para a sua atual configuração urbana. Atualmente, esse parcelamento desordenado do solo, constitui-se num emaranhado tanto de ruas, como de casas que avançam sobre o leito das vias, provocando, assim, uma composição desordenada do espaço de circulação, fato esse que se constitui num problema de fluidez de veículos e pessoas que percorrem esses caminhos estreitos e tortuosos, os quais, muito se assemelham a um verdadeiro labirinto urbano, pelo fato de ruas apresentarem linhas sinuosas entrelaçadas e intricadas.

The Escritório Saturnino de Brito (Saturnino de Brito Office), created in 1920 under the sanitaristic guidance of the engineer Saturnino de Brito, has a vast record of works throughout the whole national territory, even after the death of its founder, in 1929 at which point his son, and also engineer, Saturnino de Brito Filho, assumed the head of the company , with a compromise to continue his father s work and assure his administrative, technical and urbanistic principles up until the early 1980s, when that institution came to an end. The scarcity of theorical studies about this Office, alongside the importance of the contributions it made in countless cities, oriented the focus of this study on its performance in Natal, where it remained from 1935 to 1969, designing, executing and managing sanitationist works and the services associated with them and going through several political, economical, social, cultural and urbanistic contexts periodicized in this work into three moments. Thus, it is intended to analyze how the Saturnino de Brito Office behaved and adapted itself to the conjunctural changes that unfolded into each of these moments, and more specifically, to observe the forms of intervention adopted the principles, the instruments and the scope aiming to verify the transition of the sanitaristic set of urbanistic ideas into the urban planning as a development strategy on a local level

The present research deals with the modernization process of the Cidade da Parahyba2, between 1850 and 1924, and its relation with the cotton economy, which represented the main source of wealth accumulation for both the private and the public sectors throughout the First Republic. This study on urban history was developed by focusing on the understanding of the city s spatial formation, and despite its emphasis on the economic aspects involved, other factors that also contribute to the development of the social life were not put aside. The modernization process of the Cidade da Parahyba was also analyzed during the period established for the study according to a chronological and thematic approach that established comparisons with the financial situation of the State, whenever this was necessary, with special attention to the contribution of the cotton economy to the State´s revenues. It was possible to detect a lack of financial help and loans from the federal and municipal administrations for finishing several public works already underway in the capital, since the federal funds allocated to the State of Parahyba do Norte were rather employed in emergency works against droughts and in agricultural development. One can then conclude that the financial resources required for the urban interventions were withdrawn from the State s treasury itself, resources that were collected mainly from activities such as cotton exportation and cotton trading. Another factor shows the interdependence between the urban remodeling and the cotton economy: during the years marked by great droughts or by hard plagues on the cotton plantations, cotton production decreased, as well as the State s finances. The first measures taken by the State s administrators were to halt all projects of urban remodeling in progress in the Cidade da Parahyba, which was, clearly, the most privileged city by the State s presidents during the period analyzed. 2 The city of João Pessoa was named Cidade da Parahyba, a designation that remained until September 1930, when it received its present-day name in order to pay homage to the president of the State, João Pessoa Cavalcanti de Albuquerque, murdered in the city of Recife in August of that same year. At that time, the State of Paraíba was known as Parahyba do Norte. Since this work is limited to a period of time comprised within the First Republic, the names employed respect the terms used in those days

Although already to exist alternative technique and economically viable for destination of used tires, quantitative data on properties of constructive elements that use the rubber waste as aggregate still are restricted. In the present work, the waste proceeding from industry of retreading as material for manufacture of composite destined to the production of constructive elements was considered. Mechanical and thermal properties of mortar had been analyzed Portland cement with addition of waste without treatment, in the ratios of 10%, 20% and 30% in mass in relation to the mass of the cement, substituting the aggregate in the trace in mortar 1:5 mass cement and sand. The size of the used residue varied between 0,30mm and 4,8mm (passing in the bolter 4,8mm and being restrained in the one of 0,30mm), being it in the formats fibers and granular. The influences of the size and the percentage of residue added to the mortar (in substitution to the aggregate) in the thermal and mechanical properties had been considered. Assays of body-of-test in thestates had been become fullfilled cool (consistency index) and hardened (absorption of water for capillarity, strength the compression, traction and strength flexural). The work is centralized in the problem of the relation thermal performance /strength mechanics of used constructive systems in regions of low latitudes (Been of the Piauí), characterized for raised indices of solar radiation.

Population growth experienced in major cities, allied to society s need of infra-structure, especially ones related to habitational demands, increases the consumption of construction materials. As a consequence, consumption of natural resources itself. Thus, due to this process, concrete is one of the most produced materials in civil construction. This is also due to the great diversity of its application, easiness in its execution and adequate mechanical performance, as well as low production costs. Following the same tendencies in construction development, the ceramic industry has intensified the production of porcelain ceramic tiles and floors. These are achieved by a fine finishing and receive polishing at the end of the fabrication process. This work researched the use of porcelain residues in polishing for the production of concrete. All of which; due to economical and environmental issues. This process aims to prove adequate destiny for this type of residue, due to environmental issues, incorporating it to the concrete itself; all of which provides economy in consumption of the materials that constitute concrete. Thus, the main characteristics of concrete were investigated through the inclusion of different concentration of the porcelain residue as additional trait element. The residue rates incorporated to the trait varied from 10% to 50% in relation to the cement mass, in the traits with plastic additives and without plastic additives. It is observed that the inclusion of porcelain residue produced a meaningful alteration in the consistency of fresh concrete. This residue has a fine granulometry and it considerably absorbed the water used in the concrete spreading, influencing the way this material is dealt with. Thus, the value of cement striking decreases with the increase of residues present in trait. The maximal incorporation of the residue was of 50%, massively, for the same factor water/initial cement. The use of residues in concrete results in an 40% increase in the compression resistance. It is also proportional to residue concentration of porcelain in the trait. The microstructure was also favored once porosity and concrete absorption decreases with the use of this residue. The parameters demonstrate the quality and durability of the concrete produced with this residue. The use of porcelain residue in concrete composition has not produced meaningful thermal behavior changes. Thermal conductivity, heat capacity and thermal diffusivity have been maintained basically constant
