In the paper analyzes the process of knowledge construction in the news regarding the emergence of massive information and communication technologies. In this context, through a qualitative approach, first we examine the potential of production, dissemination, access and use information in a technocratic perspective, and secondly, the negative impacts stemming from the computed mediation, mainly linked to the complexity of policies of democratization of access to information and loss of criticality of science. The focus of this review focuses on the current model of information search and knowledge construction through the Web, outlining aspects inherent to the process in general. Similarly, envision different contributions of information science for the systematization of human knowledge, guided through the social actions of professionals working in various fields, with emphasis on the information representation and retrieval. It is hoped that work can contribute to the current thematic reflection on the production, dissemination and use of information as well as on digital inclusion policies.

Devido às crescentes pressões antrópicas sobre os ambientes naturais e o decorrente desmatamento, fragmentação florestal e extinções locais, diversos processos ecológicos importantes para a manutenção da biodiversidade estão sumindo. Diante de tal cenário a restauração ecológica vem avançando consideravelmente nas últimas décadas visando à recuperação de ambientes degradados e restituir os processos ecológicos intrínsecos das comunidades. Um dos principais processos intrinsecamente relacionados com a manutenção da integridade do ecossistema é a dispersão de sementes. Neste aspecto as aves oferecem uma enorme gama de serviços, funcionando como elos móveis que ativamente se deslocam na paisagem, conectando habitats no espaço e no tempo, mantendo sua memória e resiliência. Dessa maneira se faz necessário ter conhecimento se está havendo a retomada de interações ecológicas em áreas restauradas. No presente estudo foram estudadas as interações entre aves e plantas ornitocóricas através da frugívoria em três áreas de restauração de diferentes idades e um remanescente de vegetação como controle localizadas no interior do Estado de São Paulo. Foram registradas 25 espécies de aves consumindo frutos de 16 espécies de plantas ornitocóricas nas três áreas de restauração. As espécies de ave mais importantes das áreas de restauração foram Tangara sayaca, Turdus leucomelas, Pitangus sulphuratus, Myiozetetes similis e Elaenia flavogaster, todas de porte médio pequeno e de hábitos generalistas. Já as espécies mais importantes de plantas foram Cecropia pachystachia, Myrsine umbellata, Cytharexylum mirianthum, Trichilia clausenii e Schinus terebinthifolius. Deixando evidente que as principais espécies de aves presentes são de porte médio pequeno e as principais plantas possuem frutos e sementes pequenos...

The problem of flooding in urban areas exist in many cities and their causes are as varied as the areas of occupancy or Valley weatherproofing Fund areas of infiltration in the drainage basin. The anthropic activity come triggering changes and impacts on the environment for a long time, and there is a growing need to come up with solutions and strategies that minimize and reverse the effects caused these risk areas. Thus, the present work will address the case study in São José do Rio Preto-SP that is an exception, since the area that is considered of risk lies in the Centre, unlike most lying on the outskirts. This will also analyze the processes of urban expansion and the situations of social and environmental vulnerability, including their interrelations in urban scale. The physical study of the area will serve as an important basis for the work, but it will focus mainly on the population and the problems which this is being in hazardous areas. We will not join a single methodology, wharever, we will follow our knowledge to adapt what we feel that fits better, every time. The importance of this study is that in addition to identifying the problems which the local population suffers with floods, lists measures that minimize the environmental impacts arising through the fostering of public policies

The crescent increasing demand of the electric power in Brazil has stimulated the implantation of Small Central Hydroelectric Power (SCHP) in several regions of the country. However, the silting up of the reservoirs is one of the main problems faced by hydroelectric power plants and SCHP. In this context, this research aimed evaluate the phenomenology and propose the enforcement of appropriate bioengineering techniques to control the intense erosive process of the hydrographical basin of the “Alto Rio Sucuriú,” that cause silting up of the reservoirs of the SCHP Costa Rica, located in the municipal district of Costa Rica (MS). In order to identify the phenomenology of the main falling in of this basin, a diagnosis of the conditions of the physical environment of the region (climate, geology, pedology, hydrology, and use of the ground) was realized. A surveying was also realized to specify the geometric feature of the falling in using the Total Station of the Ruide brand, series RTS 860R and the geodetic GPS of the Ashtech brand and the data obtained was used on the preparation of the Digital Elevation Model (DEM) of the falling in. Based on this diagnosis an official register of the falling in was done with identification of the different types of present erosion. Due to the advanced erosive stage of the falling in researched, the use of bioengineering techniques could be the best solution considering that the traditional engineering techniques make use of heavy material like concrete, iron and large machines that besides causing higher impact to the natural and esthetic aspects of the environment also require a higher investment of capital. This research establish a great cooperation to the knowledge of the erosive process and of the rehabilitation of the degraded areas with application of bioengineering techniques not only hydrographical basin of “Alto Rio Sucuriú” but also to other basins that show similar situation

There is a demand to incorporate the nature in the city in order to meet the wishes of the entire population. The valuation of water, a key component of the quality of the landscape, becomes a key element in this context both for its ecological potential because of their potential for recreational activities. The areas that suffer most impacts are the Permanent Preservation Areas (PPAs) and this paper will be a weighting on the urban interface - PPA. With the study area the basin of the stream of Limoeiro, in the context of the Friendship Fountain Balneary, especially the source contained between residential neighborhoods Maré Mansa and Parque Imperial, the city of Presidente Prudente and Álvares Machado, Sao Paulo, this paper aims to search and use of knowledge about technologies and techniques of environmental restoration, with emphasis on bioengineering, through an environmental characterization of the basin, with a view the incorporation of nature in the lives of the urban population. The methodology includes: literature review priority issues related to the PPAs, linear parks, relevant environmental legislation, environmental characterization of the watershed of the stream Limoeiro; study of technologies and techniques for environmental remediation of soil bioengineering and implementation of parks linear, development of proposals for the environmental recovery of PPA in the basin of the stream Limoeiro, focusing on emerging...

As leishmanioses são enfermidades infecciosas que costumam afetar populações de países de clima tropical e subtropical, em sua maioria subdesenvolvidos, uma vez que seus principais vetores necessitam de condições ambientais e climáticas adequadas facilmente encontradas nessas regiões, para se proliferar. Há diferentes formas clínicas que se caracterizam por sua evolução crônica, sendo a forma visceral (LV) uma das mais graves. Neste caso, a disseminação é relativamente rápida uma vez que existe também a abundância de um dos seus principais reservatórios domésticos, o cão, que vive bem próximo ao homem, o qual é também acometido por esta zoonose. Dessa maneira é preciso que as populações, principalmente aquelas localizadas em áreas endêmicas, saibam identificar os pontos principais dessa doença como a transmissão, sinais clínicos e prevenção. Por esse motivo, essa revisão sistemática objetivou procurar saber qual o conhecimento de diferentes populações sobre as leishmanioses. Foram utilizados os seguintes descritores: (knowledge) AND (population) AND (leishmaniasis), através de um levantamento bibliográfico em três bases de dados, LILACS, SCIELO e PUBMED. Foi possível concluir, através da análise de sete artigos, que o conhecimento das leishmanioses ainda se encontra muito superficial dentro das populações e que a principal fonte de informação ainda é a informal, de pessoa a pessoa
