The city of Jacareí above average presents a economic growth of the State of São Paulo, fact that comes if reflecting in the quality of life of the citizens, due to lack of infrastructure to hold the growth rhythm. Today the commercial center of the city, presents diverse urban conflicts with its narrow streets and sidewalk making it difficult to the locomotion and the access the areas and building of public interest gifts in this region. Aiming at the arrival of four multinationals that already make gratings investments in the city and the promise of growth and dinamização of the still bigger economy for the next years, this work studies the urban mesh of the city for a possible implantation of a Technological Park that serves of inductive element of the development of the region north of the city of Jacareí. Place, in which, they are being constructed the multinationals and where, according to Managing Plan of the city, the city hall intends to urbanizar in the next years, with the objective to minimize the areas of urban conflict in the commercial center and of form to absorb the growth of the city. From the study of old experiences, of works carried through on the subject, interviews with city planners of the e region after visits to the place, we will go to argue the possibility of implantation of the Technological Park in Jacareí and optimum place for its installation

In the information society, the use of Technologies has been incorporated to our quotidian. The use of personal computers and internet, however, does not reach to all the individuals, creating the problem of digital exclusion. Nowadays, many inclusion politics are being developed to diminish the digital abyss in society, in a way to enable a plural access to the internet. Between these initiatives, we highlight the projects of digital inclusion among the elderly, slice of the population that grows more each day and seek quality of life, social reinclusion and health. In this context, the open universities for the elderly bring to the aged courses and workshops, in order to encourage the activity in this age group. An example of this idea is the Unati of UNESP Bauru, that develops the project “Terceira Idade Digital”. This work aims to analyze the relation between the elderly with certain technologies, apart from showing the digital inclusion scenario, with its delays and progresses

This project was developed with the aim of contributing to the construction of a system of Unidades de Saúde da Família (USFs) to Presidente Prudente, a city located in the western region of São Paulo state. It was tried to bring to the architectural space the existing guidelines for the public service with the intention of create welcoming and functional environments and a net identity. Given these characteristics it was developed a modular construction system that allows the creation of new units in an agile manner and with a minimum quality standard. Since many of Presidente Prudente’s features are present in other Brazilian cities, the guidelines presented in this proposal will be useful to the work of managers in other cities of the country

O objetivo desse trabalho foi discutir a participação das diferentes instituições integrantes da Rede de Agroecologia Mantiqueira-Mogiana, organização social com enfoque no desenvolvimento comunitário coordenada pela Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA), que trata da construção coletiva do aprendizado e da troca de experiências e intercâmbio de tecnologias em Agroecologia. Para tanto, foi proposto que as instituições participantes da Rede de Agroecologia respondessem um questionário que abrangia tópicos acerca da participação de tais instituições bem como de estruturação e gestão da Rede. Tendo o estudo tratado da participação das instituições, foram contatados os profissionais dessas organizações envolvidos diretamente com as atividades da Rede, por ser de conhecimento prévio que tais instituições são representadas no projeto por um determinado profissional com maior identificação pessoal com o campo da Agroecologia. Tais opiniões foram posteriormente analisadas enquanto representativas das instituições as quais esses profissionais estão vinculados. Os dados obtidos revelaram a necessidade de um acordo formal entre a Empresa Brasileira de Pesquisa Agropecuária e as instituições participantes do projeto, o que permitiria que os profissionais pudessem participar de forma mais efetiva das atividades da Rede de Agroecologia, integrando as atividades do Colegiado Gestor com as atividades das instituições as quais esses profissionais são vinculados. Foi possível observar também que para que os objetivos de uma determinada rede de desenvolvimento comunitário sejam atingidos é necessário que estes estejam em consonância com as motivações que as instituições parceiras apresentam para participar de tal rede. Dessa forma, é possível congregar esforços de todas as partes para que o objetivo coletivo seja atingido.

The present research aims to identify conceptions that teachers and students of the early years have in relation to the disciplines of history and geography. The site chosen for the survey was a municipal school in the city of Lençóis Paulista, in São Paulo. The work's theme was chosen after observing a minimization of the teaching of the contents of the above-mentioned disciplines at the expense of mathematical content and mother tongue. In addition, there were difficulties arising from the standardization of education , such as teaching network uses material apostilled . The survey data , together with literature review was conducted with students and teachers in the early years who participated in a semistructured interview . Authors like Callai (1999 and 2005), Cavalcanti (2005 and 1998) and Burke (1992) theoretically supports the research . They have in common a new conception of education that values the small deeds that result in major events. The student, in this view, plays an important role as a subject of social transformation. The research has favored both the analysis of the conceptions of teachers and students, assisting in reflection on teaching practices, but also led to reflect on the training of teachers. The research shows us that the type of material used and the practice adopted may impair the access of students to the language of nature and society

A monitoring network of atmospheric electric field covering the Vale do Paraiba region was implemented. The sensors were located on different sites with different altitude and geographic topology. The present work reports the study carried on those sensors in order to verify the necessity of using some correction factor to the measured local electric field intensity due to effects of local environment. The measurements were done in continuous 24 hours per day with the data recorded on registers in each device accumulating information during a period of four months. The relation between the electric field values by each sensor was compared to the reference located on Sao Jose dos Campos city using the same period. In a graphical analysis using the local field intensity and the reference, the data were fitted to a straight line obtained by minimum square method. Variation up to 95% was observed between the field values in some sensors. Another method was proposed, comparing the mean values of the electric field in a function of time. The variation in some sensors reached up to 133%. We conclude that the variations are due to local atmospheric conditions and no correction factor is required on the electric field sensors

Distribution networks are formed by long lines that carry electricity substations to homes and industries. These lines have associated impedance and depending on operating conditions of the network these impedances may vary. This paper provides a detailed analysis of the effects observed in studies of voltage drop, short circuit and electrical losses, when considered the drivers sequence impedances used in primary distribution network at different temperatures. Therefore, it is initially presented a calculation methodology and details the factors that influence the final values. The methodology presented tackles in a practical way the main factors that directly or indirectly influence the values of the impedances as an emblematic example and will be properly dealt with throughout the paper is the effect of temperature on the values of the sequence impedances. More specifically is dealt with the case of XLPE cables protected, by having a higher maximum operating temperature than the operating temperature of the network. The effects observed in the power flow generated when considering the impedance values at both temperatures were analyzed. The impedance drivers tend to increase with increasing temperature. Thus the impedance of the conductor XLPE protected will tend to be greater for the maximum operating temperature for which the operating temperature of the network, resulting in greater voltage drop and higher electrical losses
