As praças de cultura no governo Djalma Maranhão

Le présent texte vise à analiser la apropriation de l'espace par le pouvoir publique. Entre les années 1956 et 1964, la ville brésilien de Natal a été administré par le maire Djalma Maranhao, dirigeants politiques marquées par des idées nationalistes, comme la lutte contre l'impérialisme et l'émancipation du peuple a travers de ce que l'on appelle « culture populaire ». Le terme a acquis une connotation politique, en même temps dans ce qui était considéré comme la plus pure manifestation du peuple brésilien. La dynamique politique signifie aussi un nouveau regard sur la ville, enquant que le désir de progrès, de industrialisation et de réformes sociales propagée dans la politique nationale brésilienne, directement traduit par des changements dans son espace physique. Dans cette orientation nationaliste, la ville a entrepris des actions systématiques à l'encontre des nouveaux besoins urbains qui se posent en même temps que tourné certains places de la ville à espaces culturelles, appelée « places de la culture ». Ces espaces sont destinés à la promotion de la culture populaire en même temps il a été un domaine stratégique de la production et la réception des valeurs défendues par Djalma Maranhao. En ce sens, nous avons demandé répondre quelle a été la position du maire face à la besoins urbaines qu'ils se posaient et comme les places de la culture sont intégré à la vie quotidienne de la ville de Natal, donnant une nouvelle signification à la place publique. Pour la construction de ce travail, nous utilisons les sources orales et de revues, de journaux et de A República et Folha da Tarde, comme le principal ressources méthodologiques

Poluição sonora: um grave problema na cidade de Mossoró-RN

In the latest decades, we have observed some environment alterations of big proportions in our planet. Sound pollution, visual pollution, water pollution, air pollution, soil pollution, all the principal kinds of environment pollution have raised in the path of economy development. In Mossoró it is not different; the environment has suffered a long and continuous damage caused by predatory abuse. The river is polluted, the ciliar vegetation of Carnauba was totally altered and with it a part of the local fauna disappeared. In fact, the city urban environment has, and continues to be, deeply altered and the sound pollution is a reflex of the urban modifications undergone in the city as time goes by. Through bibliographic review, the gauging of noise and fieldwork, this research project had the objective of analyzing the principal activities that cause sound pollution in the urban perimeter of the city of Mossoró, RN, emphasizing the causes, effects and spacial distribution of the polluter agents, as well as understanding how the environmental laws treat the sound issue in the urban environment of the city. The President Dutra avenue, where popular events of Mossoró take place and an important access for the city, was the chosen place to study this pollution that became, recently, another hindrance that interferes on the life quality of the local population. The results of this brief research emphasizes the urgency to alert society, specially about the importance of law and public organs that are located in our city, therefore solving problems such as the aforementioned above

Análise da mobilidade urbana de Natal/RN a partir do uso de indicadores de sustentabilidade

In contemporary times, the urban mobility is presented as one of the main challenges of large and medium-sized Brazilian cities , it presents signs of unsustainability , above all due to the increase in motorized transport system , especially the individual . Thus , it is clear that mobility is considered of special interest for sustainable urban development , is facing a crisis that is reflected in negative externalities , particularly with regard to congestion , accidents , air pollution , social exclusion , among others. The complexity of these problems requires an integrated analysis based on the principles of sustainability . In this sense , trying to understand this problem and in the attempt to minimize its impacts, Costa (2008 ) proposed the Index of Sustainable Urban Mobility (I_SUM) with the goal of providing a methodology capable to assess relevant aspects of mobility , including social dimensions , political, economic and environmental . Given the above, was elected as the main objective of this study is to analyze urban mobility in Natal / RN from the perspective of sustainability . Like specific objectives will seek to analyze Natal´s urban mobility, using the I_SUM like a tool for both the city as a whole and for each of its four administrative regions; evaluate Natal s urban accessibility conditions and verify to what extent the access to urban services and equipment is facilitated or hindered because of the location and incomes of the population . For this, it was necessary to use bibliographic , documentary and field research . The index , which varies from 0.00 to 1.00, revealed for Natal an Global value of 0,510, and that refers to its administrative regions, it was found that there are very small percentage differences from the overall index calculated for the city . The performance of I_SUM by administrative region showed that although there are differences , the results were very similar , varying between 0,494 and 0,537. Particularly in relation to urban accessibility, it appears that Natal presents as an unequal city and this inequity , which is not only income is reflected in the issues related to accessibility and hence urban mobility

Quilombolas e desenvolvimento sustentável: análise a partir da comunidade Capoeira dos Negros (Macaíba/RN)

Quilombo communities remaining are groups marked by insufficient public assistance and characterized by living in rural and conducting economic activities such as agriculture. The development on a sustainable basis is important to ensure strategies for economic growth and environmental preservation. This work aims to study the remaining Quilombo Capoeira Black community, located in the municipality of Macaíba, Rio Grande do Norte, considering the principles of sustainable development. Attempt to respond to what level such community can be considered sustainable from an analysis of their social practices. The methodological procedures used consisted of a literature review and documentary, questionnaires, conducting semi-structured interviews and direct observation. The final results show that the family farm has characteristics that approximate the principles of sustainable development, including the diversification of labor, food production with less environmental damage and strengthening the rural environment, and indicate that the main economic activities practiced in Capoeira dos Negros community are agriculture, manufacturing of cassava flour and brick manufacturing, which, in turn, are linked to negative environmental impacts, such as sedimentation pond, groundwater contamination, air pollution and soil erosion. What lead to the conclusion that the social practices of the community are not in line with the dimensions of sustainable development. It is hoped that the survey results provide subsidies for development and implementation of public policies

Poluentes atmosféricos: monóxido e dióxido de carbono no nordeste do Brasil

The interference of man in the middle atmosphere can be evidenced by the presence of carbon monoxide, gas associated with burning fossil fuels and carbon dioxide content, essential for respiration of plants and thermal balance of the Earth. In this thesis we initially evaluated the intensity of the spatial distribution of carbon monoxide in the Northeast of Brazil, and subsequently the behavior of temporal variations of the pollutants carbon monoxide and carbon dioxide in the atmospheric boundary layer Maxaranguape / RN. Research has shown that, driven by speculation and promoting the occupation of land for agriculture, cattle ranching and tourism in the Northeast of Brazil, the changes established by the man in the middle geomorphological affect the lower troposphere on a large scale, with a predominance of concentrations in central Pernambuco, Paraiba's south-central and central-west of Alagoas. However, the study of Maxaranguape / RN results showed little variation in carbon monoxide and carbon dioxide, with the speed of the wind persisting with values greater than 7.8 m / s, showing dispersion and diffusion of pollutants which resulted in faster renewal of local atmospheric air
