Esta dissertação apresenta um estudo exploratório sobre a experiência de implantação de um sistema digital de segurança. O estudo teve como locus a Guarda Civil Metropolitana de São Paulo e o objetivo geral da pesquisa é analisar o uso das tecnologias da informação e comunicação no campo operacional da organização. Primeiramente foi realizada a pesquisa bibliográfica para rastreamento de temas análogos. Foi possível verificar a escassez de estudos sobre as tecnologias da informação e comunicação na Segurança Pública no Brasil. Dos raros trabalhos encontrados o que deu inspiração para essa pesquisa foi o experimento realizado em Brasília, na área de Gestão do Conhecimento e da Tecnologia da Informação, que investigou a integração de sistemas de info rmações na Segurança Pública do Distrito Federal. Para a realização deste estudo de caso adotou-se a metodologia qualitativa com pesquisas bibliográfica, documental e de campo (entrevistas e observações diretas). Os resultados obtidos demonstram a necessidade de investimentos em tecnologias da informação e comunicação, objetivando a integração e a interoperabilidade das organizações de Segurança Pública. Os resultados também confirmaram os achados em pesquisas e estudos sobre a violência urbana que apontam que só os investimentos na estrutura técnica, em pessoal, em gestão de segurança, chamada política de combate à violência e à criminalidade, não resolve. É preciso urgência na gestão de políticas públicas integradas para combater as causas provocativas da violência e da criminalidade que são a miséria crescente, o desemprego, a falta de serviços públicos eficientes, em especial no setor da saúde e da educação e a ausência de políticas sociais, todos entendidos como violência.(AU)

The public political investments of urban mobility financed by PAC of Cup 2014 have developed discussions and questions by the civil society in Brazil expecting positive results to the urban infrastructure referring to the possible human rights violation and, specially, rights of habitation related to the removing/expropriation noticed. Natal, capital of Rio Grande do Norte, is into this context, due to the urban mobility project linking North Zone of the city to the Arena das Dunas stadium, financed by the PAC of Cup 2014, named West Structural Corridor, that crosses a field of social interest and proposes almost 400 expropriations. This research analyzes how strategies and mechanisms of integration were presented between the mobility project of West Structural Corridor and the Social Interest Habitation affected by this project. We have as hypothesis those projects financed by PAC of Cup 2014/Urban Mobility to Natal/RN present many problems related to the integration of social interest to the housing project, however the National Politics of Urban Development has planned this integration. As a result we detach 3 strategies in the elaboration process about the integration of those politics: (i) integration between municipal secretaries involved in this project; (ii) urban integration of the city; and (iii) integration of public rules or public politics integrated. For each strategy were presented the main mechanisms used to establish the integration of the project. Those mechanisms, however, in this process of establishment/implementation of the empirical research, presented many contradictions and conflicts that compose problems to the integration between the mobility project and the housing area affected.

The metropolitan regions of Northeast Brazil are being gradually included in a scenario of international investments, which are motivated by the restructuring of both touristic and real-estate sectors. The new capital, real-estate developers and space configurations that result from this process indicate the need for the creation and implementation of public tools which should, at least, allow the mitigation of the urban impacts and environmental losses resulting from this situation. The effects on landscape and on the socio-spatial configuration result from the intensification caused by the dynamism of the "real estate-tourism" sector. There is a regional integration as an expression of the urban expansion of the metropolitan area of Natal. This study investigates the uniqueness of the restructuring and territorial integration of coastal areas and the strategies of the circuit of capital accumulation formed by linking the real estate to tourism. It is intended to increase the understanding about the strategies of tourism, real estate and public policy agents involved in this territorial reconfiguration and in the fund-raising needed for the investments, to understand the existing social and environmental effects and their future trends and also to understand the forms of spatial production as results from the practices of approaching the land transformation and the tourism valorization of the landscape, in a synchronous manner, first in the Northeast region and, as a focal study, in the Metropolitan Area of Natal. Likewise, it is intended to apprehend the current processes of metropolization of the eastern coast of Rio Grande do Norte, in addition to indicate its physical-territorial transformation and the types of projects/developments promoted by the market in the recent period. Based upon analysis undertaken for the Metropolitan Region of Natal RN, this piece of work presents some considerations on possible legal instruments that can be adjusted to the municipalities which are experiencing the impact of this peculiar and recent phenomenon in the region, caused by the arrival of the real estate-touristic capital. It is also intended to point out basic proposals to the forms of public intervention, in a speculative way, starting from a Metropolitan Planning project within a medium and long term

This study intends to establish a relation between environmental degradation, particularly the devastation of the green canopy, and public health. Utilizing a mapping of the trees included in the researched area, each individual tree was analyzed according to its age, taxonomic listing, architecture, shape and size (determined by aesthetic/convenience reasons or deformed by pruning). Initially investigated were the covert reasons lying underneath the constant aggression against trees (which many times seem to contain elements of hatred and contempt) within the urban environment. In addition to that, the aspects concerning environmental modifications and the consequent impact on public health were also assessed. Two main problems promptly emerged as a result of the removal of trees: a) without a canopy to protect the areas, they became subject to winds directly blown from SW Africa and impregnated with aerosol partic les, which are common causes for respiratory disorders and, b) direct UV solar radiation, which causes some types of skin cancers and eye disorders. To reach such results, we studied the origins and formation of UV radiation induced cancers and searched for the UV radiation spectra of action, e.g., usual intensity and quantity reaching clear and shadowed spaces in a certain area and its consequences. In a second instance, we also searched for pertinent data resources in order to confirm the increase of skin cancer cases due to exposure to UV radiation and the relation between the destruction of the green canopy and the above mentioned problems. We believe that a few significant results have been achieved by this study, namely: the relation between a culture based on medieval beliefs and its consequences on the environment; how this culture exploits and deforms nature in pursuit of financial and psychological interests to a point of transforming the landscape into a copy of something devoid of any relation to latitude and altitude; and above all, the indifference concerning the alarming results carried by these modifications

This study aimed to evaluate the population ecology of Hydrochoerus hydrochaeris (Linnaeus, 1766) in two urban areas in the north of Paraná, an open and other protected by assessing the effects of these two different types of environments on the structure and dynamics of the population and its implications for conservation of the species. The monitoring of the populations were performed monthly between June 2014 and March 2015 in Jaboti Lake Park (Apucarana / PR) and Conservation Unit Parque Arthur Thomas (Londrina / PR). To conduct the survey population data was used the methodology of total census (direct counting of individuals).They were evaluated ecological parameters of the populations of capybaras, such as ecological density, abundance, age distribution and birth rate, as well as performed the analysis of the landscape. It was applied to analysis of variance (ANOVA) to test the differences between the averages of the abundance of each age group per year of observation, as well as the differences between the average ecological density over the years of observation. The standard relationship between the use of classes and land use in the landscape and the ecological parameters of the capybara populations was evaluated by Principal Component Analysis (PCA). The trend of variation of average abundance over time to Thomas Arthur Park revealed abrupt decrease of the population in a short period of time (2014 16 ± 9, 14 ± 1 and 2015 7±1) as well as ecological density in 2015 (0.05 ind./ha). On the other hand, the Jaboti Lake Park, showed an increase in absolute abundance, with marked recovery of the population in the same period (2014 38±8,30 and 2015 45±1,73) and coming up with an ecological density in 2015 (2 ind ./ha). The birth rate found Lake Park Jaboti was superior to Arthur Thomas Park, which had a negative rate between 2012 and 2015. The use and land cover analysis showed significant differences from the point of view of the relative contribution of landscape elements in the spatial heterogeneity. Arthur Thomas Park shows areas of dense vegetation and urban areas relatively higher than those observed in Jaboti Lake Park that revealed relatively higher proportions of the areas of agriculture / field and exposed soil. Thus, the present study revealed that the local population structure is directly related to the spatial characteristics of both studied landscapes, as can be seen by the greater abundance and density seen in Jaboti Lake Park compared to Arthur Thomas Park in recent years of study.

Air pollution can threat the environment and public health, and is assess by pollutant ́s concentration measurements in order to verify whether the limits set by environmental agencies are being respected. However, these measures do not indicate immediately the impacts to living beings. To faced this problem, plants are been investigated as potential bioindicators of air pollution and, among them, stand out bromeliads Tillandsia genus which colonize various substrates,. obtaining water and nutrients from the atmosphere directly. In this context, this research assessed the potential of epiphytic bromeliad Tillandsia recurvata (L.) L. found in urbanized areas of the city of Curitiba - PR as a bioindicator of urban air pollution. According to vehicle traffic, five sample points were selected and classified. Points P1 and P2 were classified as high-traffic vehicle due presenting trucks and urban transport; point P3 was classified as moderate traffic due the predominance of private vehicles and urban transport; and points P4 and P5 were classified as low-traffic, presenting circulation of private vehicles only. There were analyzed the abundance of T. recurvata, morphophysiological parameters (leaf area, leaf specific area, sclerophylly index, percentage dry weight / fresh weight, chlorophyll (a + b), analysis of structural mesophyll organization) and the heavy metals accumulation (Fe, Cd, Cr, Cu, Pb and Zn). The abundance analysis and the results obtained for metals analysis were correlated with the intensity of vehicular traffic, directing the sampling points P1 > P2 = P3 > P4 = P5. This result demonstrate that the abundance of T. recurvata is greater in urban air pollution impacted areas, thus indicating that T. recurvata absorbs and accumulates metals and can be used in biomonitoring of urban air pollution in areas impacted by vehicular traffic. Morphophysiological parameters analyzed shows that the internal plant ́s structure is not significantly impacted by urban air pollution due plant ́s adptations. The presence of absorbing scales, the CAM metabolism pathway and it ́s store water ability, among other features, demonstrate their potential as bio-indicator in urban areas, especially regarding heavy metals accumulation .

Urban paving is of paramount importance for a city, both socioeconomic and in quality of life. The urban flooring not different so-called road surface are constituted by a set of horizontal layers, overlaid on the ground, which have the main function of supporting the actions induced by the vehicle redistributing the stresses transmitted to the ground. Soils are important materials for the execution of paving, mainly because they are part of the basic structure of the floor and mostly be available in abundance, with a very low cost, however, their properties usually do not meet the requirements necessary to perform the floor. The soil stabilization for the implementation of urban pavement bases and sub-bases is an increasingly important aspect in the current situation, because always there is the concern with the environment, and there is now the clear awareness that every effort should be made to minimize the effects caused by the exploitation of deposits and deposition of material. In this sense this work presents the effects of adding different proportions of lime to stabilize a sedimentary soil sample from the urban area of the city of Curitiba. It selected a sample quantity of soil in the region to study the stabilization insertion of hydrated lime type (CHIII) powder. The two variables in the study are related to the content of lime mixed with the soil at 0% percentages of 3%, 6%, 8% and 16%, and cure times at which these mixtures were subjected to (0, 7, 14, 28 and 56 days). The tested mixtures were prepared from dosages defined by two methods: one checking the chemical behavior of the samples by means of changes in pH values, and the second analyzing the mechanical behavior through the RCS values. It has been found that the chemical stability analyzed by addition of lime, provided an average increase of RCS in most soil samples studied, because of some physical and chemical characteristics thereof. For mixtures with 6%, 8% and 16% of lime after 28 days of curing, the average RCS was 0,57 MPa, 1,06 MPa and 2,37 MPa, respectively, for the normal proctor, and as for intermediate proctor, in the same curing time and on the same percentages RCS results were 0,54 MPa, 1,04 MPa and 2,71 MPa, respectively. In global terms, the soil-lime mixtures studied showed acceptable behavior by law to use as layers of sub-base. However, only the mixture with 16% of lime, at 28 days, is recommended for use on floors bases. Even so, the mixtures studied constitute a good alternative economic and socio-environmental.

Coleodactylus natalensis Freire, 1999, an endemic species of Atlantic Forest fragments around the Natal municipality, Rio Grande do Norte State, Brazil, has as type locality the Parque Estadual Dunas de Natal (05º48 S to 05º53 S and 35º09 W to 35º12 W), one of the largest restinga (herb and shrub association on sand dunes along the Brazilian coastline) associate fragment, surrounded by urban zone, placed on setentrional Atlantic Forest limits. We made estimates on populational density, spatial distribution, habitat and microhabitat preferences and feeding ecological aspects like sazonal and sexual variations on diet, prey electivities and niche breadth. We randomly sampled ninety-six 50m2 quadrants in each of the four habitats identified in the study area. Were collected 49 specimens and their stomach contents were analyzed; prey items found were correlated with leaf-litter invertebrates from habitat samples. We found a 98,5 ± 75,5 individuals/ha density, in grouped distribution pattern on densest habitats and random distribution on others habitats. This species lives mostly on leaf-litter in forest habitats, in higher humidity points, with lower temperatures, deeper leaf litter and lower sea level elevations than the randomly chosen points in the study area. Isopoda and Aranae were the most important prey categories in numeric, frequency and volumetric terms. Niche breadth has an intermediate value and was variable in sexual and in habitat terms. There was no correlation between morfometric measures and prey size on diet. The C. natalensis population studied seems to be diet opportunist, although selects larger prey items. The Parque Estadual das Dunas do Natal has several indications of anthropic pressure from the surrounding urban area that may affects the local C. natalensis population. Thus, the fragility of this species calls for urgent conservation efforts

As cidades médias brasileiras apresentam potencialidade para investimentos. Isto implica no surgimento de novas demandas e na necessidade do fortalecimento da gestão municipal. O lento avanço das políticas públicas urbanas para promover ordenamento urbano sustentável é preocupante. Entre os problemas encontrados nos grandes centros urbanos e já verificados nas cidades médias está a situação do sistema de transporte urbano. Este apresenta uma matriz de deslocamento não sustentável. O presente trabalho tem por escopos apresentar as diretrizes da Política Nacional de Mobilidade Urbana (PNMU) e diagnosticar a mobilidade de pedestres, ciclistas e usuários do transporte público da cidade de Araguari e sua forma de organização. A metodologia a ser utilizada consiste em pesquisa bibliográfica referente às temáticas da urbanização, planejamento e mobilidade urbana. Será realizado levantamento de dados primários e secundários, além do apontamento das características a serem exploradas e das fragilidades a serem combatidas através de um processo de gestão.

O presente artigo apresenta os resultados de uma pesquisa sobre as dinâmicas socioeconômicas ocorridas nas últimas décadas na formação territorial do Estado do Paraná, no Brasil, proporcionado pelo avanço tecnológico em comunicação e informação. Essas novas formas de organização territorial, onde a base urbana tem despertado grande interesse de segmentos para investimentos imobiliários, atividades industriais, bancárias e tecnocientificas, têm proporcionado a algumas cidades do Estado do Paraná se destacar como pólos de crescimento regional formando pólos tecnológicos. Dentre os 399 municípios do estado, 14 com população entre 100 a 500 mil habitantes, têm despertado interesse dos investidores, tanto regionais, nacionais como internacionais, ampliando assim as relações econômico-financeiras com cidades maiores ou regiões metropolitanas, sendo escolhidas pela sua densidade social e econômica, infra-estruturas de qualidade e suporte financeiro, como pólos tecnológicos. Londrina, localizada no Estado do Paraná, Brasil, tem-se projetado no cenário nacional e internacional, pelo seu desenvolvimento na área tecnológica, favorecida pela presença de institutos de pesquisa agropecuária, universidades com cursos de graduação e pós-graduação, empresas do setor de informática de grande porte técnico e científico, reforçada pelo dinamismo agroindustrial. O setor de ensino e saúde polariza e consolida Londrina como importante centro de serviço regional.

A alteração da estrutura da paisagem para um novo estado no contexto urbano leva a modificações dos elementos naturais em função do crescimento da população e da ocupação de novos espaços. A arborização urbana participa dessa transformação, pois é um elemento qualificador das cidades. Assim, esta pesquisa tem por objetivo analisar a relação da configuração espacial da arborização urbana em quatro bairros da cidade de Ponta Grossa – PR, a partir de dados de inventários da composição florística viária levantados nos anos de 2005 a 2008, cruzados com aspectos socioeconômicos da população apontados pelo Censo Demográfico do IBGE (2000).
O PROCESSO DE FORMAÇÃO DA REDE URBANA BAIANA: O MUNICÍPIO DE CANAVIEIRAS- BA NA REDE URBANA REGIONAL
Resumo:
A intensificação do processo de urbanização no Brasil a partir do século XIX condicionou mudanças cruciais na sociedade caracterizando novos padrões de produção, de distribuição e de consumo. A rede urbana, nesse contexto, passou a ser o meio através do qual a produção, a circulação e o consumo se realizam efetivamente, articulando distantes lugares e estabelecendo uma economia e um território nacional. Dessa forma, é de fundamental importância entender a rede urbana como um arcabouço que reforça e influi nos conteúdos sócio-econômicos do território, sendo, portanto, uma dimensão sócio-espacial da sociedade. Pensar a cidade, e de modo especial as pequenas cidades e seu papel na rede urbana nacional e regional permite-nos considerar as especificidades apresentadas pelas mesmas na formação e desenvolvimento urbano do país. O presente trabalho está sendo desenvolvido como parte da revisão bibliográfica do curso de Mestrado em Geografia, no Programa de Pós-Graduação MINTER entre a Universidade Estadual de Campinas (UNICAMP) – Instituto de Geociências e a Universidade Estadual de Santa Cruz (UESC). Essa etapa da pesquisa consiste num estudo de caráter bibliográfico, através do qual objetiva-se analisar o processo de formação da rede urbana no sul da Bahia buscando compreender o papel dos centros de pequeno porte, como a cidade de Canavieiras, no contexto da referida rede. O estudo será norteado pela concepção proposta por Milton Santos (2004) ao considerar que a rede urbana funciona a partir dos dois circuitos da economia urbana e por Roberto Lobato Corrêa (2001) ao afirmar que uma das características marcantes da estrutura dos sistemas de cidades é a organização hierarquizada dos centros urbanos, que variam conforme o tamanho, a qualidade funcional e a extensão da zona de influência espacial dessas aglomerações.
