Crianças no pátio escolar :a utilização dos espaços e o comportamento infantil no recreio

The interest for understanding the relationship of the child with its environment has increased in the whole world during the last few years. Several researchers, using Environmental Psychology as basis, have analyzed the implications of this relation for the child development and the organization of playful spaces. Being a place where children spend a great part of their time and develop many intellectual and social abilities, the school becomes one of the main focus of this research. This study investigated different sectors of the outdoor area of NEI -UFRN, during the recreation time, in which the use of space and the interaction between children were analyzed, through the observation of the child behavior (place-centered and individual-centered mapping). The results had disclosed that the school s outdoor area and its equipments presents a great range of choices possible to the children, however its occupation is not uniform: there are areas very used and others almost without use. Generally, this heterogeneity happens again in relation to the distribution of the interaction states in the sectors, the friendly associative behavior being the most present. The observation of children behaviors favored a better understanding of the use of the spaces, and contributed for discussion about the environment what these users really need for a healthy development, including differences in related to gender, age and daytime. In spite of the studied outdoor areas being vast, pleasant and varied, it needs a better distribution of its equipments and a plan that allows greater children participation in the place organization

Construção de mosaicos georreferenciados usando imagens aéreas de pequeno formato

In this work we propose a technique that uses uncontrolled small format aerial images, or SFAI, and stereohotogrammetry techniques to construct georeferenced mosaics. Images are obtained using a simple digital camera coupled with a radio controlled (RC) helicopter. Techniques for removing common distortions are applied and the relative orientation of the models are recovered using projective geometry. Ground truth points are used to get absolute orientation, plus a definition of scale and a coordinate system which relates image measures to the ground. The mosaic is read into a GIS system, providing useful information to different types of users, such as researchers, governmental agencies, employees, fishermen and tourism enterprises. Results are reported, illustrating the applicability of the system. The main contribution is the generation of georeferenced mosaics using SFAIs, which have not yet broadly explored in cartography projects. The proposed architecture presents a viable and much less expensive solution, when compared to systems using controlled pictures

Lazer e urbanização: a dinâmica do setor de serviços no litoral de Parnamirim e Nísia Floresta - RN

The research here undertaken analyzes the process of urbanization on the coast of Panamirim - RN and Nísia Floresta - RN, arising from leisure, the main leisure expression was considered the second residence and coastal tourism. The leisure promoted the growth of businesses and public and private services to meet consumer demand in that area, which initially occurred with users of second home, and which also gradually begin to occupy the coastline of these municipalities in 1980 and more recently with the development of tourism in the 1990s until now. To undertake such an analysis, we did the georeferencing about the trade and also public and private services of that coast, characterizing them; evaluated the extent to which services deployed in this area meets the demands of tourists and users of second residence; it was also identified how the centrality of Natal interferes in the expansion of services in these locations. The spatial area of research includes the coastal municipalities of Parnamirim and Nísia Floresta, considering the limits of the census of the Instituto Brasileiro de Geografia e Estatística- IBGE, and about the time frame, it was considered the 1990s to the present day. The methodology consists of: 1. survey and reading of the literature related to the researched topic, serving as the theoretical analysis in the construction of the object studied; 2. collection and organization of secondary data by the IBGE and tourism sectors of the State of Rio Grande do Norte, Natal and main municipalities of the research; 3. Questionnaires and / or interviews with the traders, service providers, tourists, users of second homes, local residents, and government. The analysis of such data collected allowed the preparation of graphs, maps and tables that illustrate the results obtained in the research field, basing so the study. The relevance of the study is shown by the extensive survey data involving agents of the research, including tourists, users of second homes and, above all, the data for the service sector that did not exist in the analyzed area. The study results identified in the area analyzed the emergence of three new centers, arising from the urbanization process from leisure, one of them located in the municipality of Nísia Foresta Beach in Barra de Tabatinga, and two in Parnamirim, more specifically in locality Pium and Beach Pirangi do Norte. It was further observed that, being located in tourist areas, the main feature of these new centers is seasonality

Piranha attacks in dammed streams used for human recreation in the State of São Paulo, Brazil

Ataques por piranhas vêm se tornando um problema comum em trechos represados de rios e córregos no estado de São Paulo, Sudeste do Brasil. em dois surtos ocorridos em dois municípios vizinhos no noroeste do estado, 74 banhistas foram mordidos. Uma mordida por pessoa foi registrada, em curto período do ano. As mordidas estão relacionadas a cuidado parental e/ou defesa do território de desova, o que reforça estudos anteriores e desmistifica os ataques por este peixe lendário, da maneira como são popularmente percebidos. A colocação de redes de malha fina e a remoção de vegetação aquática cessaram os ataques.

O processo de urbanização turística em Natal: a perspectiva do residente

The objective of the study was to analyze and discuss the process of urbanization in the tourist city of Natal focusing on the actions of the resident agent as a producer of space tourism. The production and expertise in the areas of the city for the performance of tourism have led to the intensification of social problems of nature that comes to few expelling the residents of the beaches. The cut space of the study included the four beaches of Natal / RN, the praias do Centro, Via Costeira, Ponta Negra beach in the Redinha. For this, was conducted a case study, using the technique of questioning, with the application of one hundred and sixteen (116) questionnaires to residents, with age from thirty-five years, between the four of the City Administrative Regions. The results show that the process of urbanization has interferido tourism on the practices of the recreation of residents in the areas as tourism has shown a trend seen in the intensifying problems of social order, such as prostitution, insecurity, pollution of beaches, etc. The combination of these problems are reflected negatively on the tourist areas and are gradually removing the residents. Through this framework problematic, given to tourist areas in the city, the resident still has not positioned the way criticizes the defense of these, choosing not express or adopting a form of discrete event, such as the gradual exit of the areas and electing tourist beaches in other municipalities. The results are of great significance for the direction of a trip planning committed with the participation of the resident in the planning process. The study is to corroborate with the importance of the participation of the resident, before the trip planning, as it is a fundamental agent for the sustainability of space tourism

Levels of toxic and essential metals in maternal and umbilical cord blood from selected areas of South Africa-results of a pilot study

This pilot study uses concentrations of metals in maternal and cord blood at delivery, in seven selected geographical areas of South Africa, to determine prenatal environmental exposure to toxic metals. Samples of maternal and cord whole blood were analysed for levels of cadmium, mercury, lead, manganese, cobalt, copper, zinc, arsenic and selenium. Levels of some measured metals differed by site, indicating different environmental pollution levels in the regions selected for the study. Mercury levels were elevated in two coastal populations studied (Atlantic and Indian Ocean sites) with mothers from the Atlantic site having the highest median concentration of 1.78 mu g/L ranging from 0.44 to 8.82 mu g/L, which was found to be highly significant (p < 0.001) when compared to other sites, except the Indian Ocean site. The highest concentration of cadmium was measured in maternal blood from the Atlantic site with a median value of 0.25 mu g/L (range 0.05-0.89 mu g/L), and statistical significance of p < 0.032, when compared to all other sites studied, and p < 0.001 and p < 0.004 when compared to rural and industrial sites respectively, confounding factor for elevated cadmium levels was found to be cigarette smoking. Levels of lead were highest in the urban site, with a median value of 32.9 mu g/L (range 16-81.5 mu g/L), and statistically significant when compared with other sites (p < 0.003). Levels of selenium were highest in the Atlantic site reaching statistical significance (p < 0.001). All analysed metals were detected in umbilical cord blood samples and differed between sites, with mercury being highest in the Atlantic site (p < 0.001), lead being highest in the urban site (p < 0.004) and selenium in the Atlantic site (p < 0.001). To the best of our knowledge this pilot investigation is the first study performed in South Africa that measured multiple metals in delivering mothers and umbilical cord blood samples. These results will inform the selection of the geographical sites requiring further investigation in the main study.

A vilegiatura marítima e a urbanização em Tibau/RN

This research aims the analysis of the urbanization process that has taken place in the coastal city of Tibau/RN in the period comprising 1980-2012, due to the (re) production of space to consumption of leisure and recreation, through the so called practice of Maritime Villeggiatura. Such practice exists so that people settle temporarily on the beach as a second home, interfering in the Regulation of the land use as well as in the urban planning of Tibau, promoting urbanization based in the logic of leisure, with enormous capacity for appropriation and space consumption. The practice of Maritime Villeggiatura in Tibau began in the late nineteenth century, becoming more relevant in the 1980s, when the practice became fashionable for the citizens of Mossoró City, in view of their economic strength, and consumption power to invest in this type of domicile. Tibau has become a great depository of second homes for leisure practice, which contributed even to the city administrative and political emancipation in 1997. The intensification of Real Estate activities, expanding second homes along the coast, results in the urbanization of Tibau territory with the assistance of Local Government, whom was interested in entering Tibau on the State tourism routes. The used methodology comprised literature review, data collection and local observation. Questionnaires were applied in the form of interviews to the villeggiaturistas, local residents, business and trade services local companies, a local agricultural firm named Agricultura Famosa Ltda., Municipal government and the Association of Senior Citizens of the municipality of Tibau. A photographic record was made to visualize the urbanization evolution of Tibau. It has also been taken georeference measures of the area object of study in this research, in order to analyze the use and occupation of the territory by urban and social agents villeggiaturistas and residents. The conclusion is that the urbanization process that has been taken in Tibau occurred along the coast shore, with low population density, and therefore creating difficulties to governance of the Municipal government. Real Estate Sector has been promoting the value increase of urban land in order to fragment the space with private condominiums segregating local resident population to outlying areas of the city, away from the coastline and lacking infrastructure and basic urban services

Spatial distribution of trachoma cases in the City of Bauru, State of São Paulo, Brazil, detected in 2006: defining key areas for improvement of health resources

Introduction: The objective of this study was to analyze the spatial behavior of the occurrence of trachoma cases detected in the City of Bauru, State of São Paulo, Brazil, in 2006 in order to use the information collected to set priority areas for optimization of health resources. Methods: the trachoma cases identified in 2006 were georeferenced. The data evaluated were: schools where the trachoma cases studied, data from the 2000 Census, census tract, type of housing, water supply conditions, distribution of income and levels of education of household heads. In the Google Earth® software and TerraView® were made descriptive spatial analysis and estimates of the Kernel. Each area was studied by interpolation of the density surfaces exposing events to facilitate to recognize the clusters. Results: of the 66 cases detected, only one (1.5%) was not a resident of the city's outskirts. A positive association was detected of trachoma cases and the percentage of heads of household with income below three minimum wages and schooling under eight years of education. Conclusions: The recognition of the spatial distribution of trachoma cases coincided with the areas of greatest social inequality in Bauru City. The micro-areas identified are those that should be prioritized in the rationalization of health resources. There is the possibility of using the trachoma cases detected as an indicator of performance of micro priority health programs.
