Orientação geográfica: uma proposta metodológica para o ensino da geografia na 5ª série

Cartographical representations (maps, charters and plans) are taken as didactic resources in Geography classes in the 5th grade of the municipal public schools in São José de Ribamar through a methodological approach taking into consideration the use of those resources is still worries an important part of the teachers of the Maranhão State public schools who teach in this level. Papers related to the theme, most of the time, are non accessible to the teachers of the maranhense public schools, mainly because the education instilutions, which use those resources, do it in a very incipient way. So this research proposes from the drawings of magnetccoursein the school courtyards, together with maps, charts, plans among others representation used in the classroom environment, motivate the students to a deeper interests in participating in Geography learning process in the 5th grade. Interviews, analyses of socialcultural questionnaires of the families involved in the process; observations of classes, trainings, geocartographical orientations, application of pre and posttests, discussions about the usage of cartographic representations, proposed and effectivated tasks in the classroom, as well as around the school, were the basis of the researched population. As a result of this process, it was produced a was complement didatical material showing, among others, the space in which students, for sure, will contribute in an effective way to a better teaching practice in the chain of maranhense public schools, having in mind that these geographic subjects may be taught in the level we focused our study

Atlas municipais elaborados por professores: a experiência conjunta de Limeira, Rio Claro e Ipeúna

Na última década, as recomendações curriculares de história e geografia para o ensino fundamental incentivaram a produção de atlas municipais, uma vez que permitem incluir num só volume mapas, textos, fotografias, gráficos, entre outras fontes de informação, a respeito do espaço local. Este artigo apresenta uma experiência em que a produção de atlas municipais se tornou projeto de pesquisa colaborativa entre pesquisadores da universidade e professores de geografia, história e ciências de três municípios. Problemas como recorte curricular, linguagem cartográfica e formação de professores consistem nos pontos principais da pesquisa, a qual traz uma contribuição significativa para a constituição de uma linha de pesquisa que vem sendo chamada de cartografia escolar.

Aplicação da geologia de engenharia na redução de risco geológico urbano em Itapecerica da Serra - SP: estudo de caso

O município de Itapecerica da Serra, Região Metropolitana de São Paulo (RMSP), possui uma população de 162 mil habitantes e cerca de 150 km² de área. As características geológicas e geomorfológicas do seu território e o fato de localizar-se quase inteiramente em área de proteção aos mananciais que abastecem a RMSP implicam restrições ao uso do solo e à expansão da ocupação nos moldes em que vem ocorrendo. O diagnóstico das áreas de risco geológico do município foi uma das atividades implementadas para a execução do Plano Municipal de Redução de Riscos (PMRR) do município. O PMRR tem por objetivo apresentar os resultados da identificação e da análise das situações de risco geológico-geotécnico, criando propostas de intervenções estruturais para a sua eliminação e/ou redução, estimativas de custo e estratégias para a gestão de risco no município. O mapeamento do risco geológico foi realizado em 35 áreas, onde foram identificados 66 setores de risco englobando, 419 moradias, sendo 175 moradias em setores cujo grau de risco foi classificado como alto ou muito alto. As propostas de intervenção estrutural buscaram a aderência entre o processo geodinâmico atuante e a tipologia de intervenção sugerida para estabilização e controle. A definição de critérios para a hierarquização das intervenções propostas contribuiu para a inserção das propostas do PMRR no planejamento plurianual do município de Itapecerica da Serra.

SPT-T: test procedure and applications

Ranzini (1988) proposed the Standard Penetration Test with torque measurement (SPT-T) and some geotechnical engineers in Brazil have been using it since 1991. This paper presents the state of the art on SPT-T testing, emphasizing what is already established as common knowledge in Brazilian engineering practice, besides a suggestion for test procedure, including equipment and practical aspects. In addition, the study of the shape of the torque versus rotation-degree angle curve obtained by an electric torquemeter used in several SPT-T tests carried out on six experimental research sites in the southeast region of Brazil is discussed here. Four different methods to predict pile capacity based on SPT-T test results are briefly presented and a comparison with load tests carried out on different types of piles, on those six experimental research sites, is presented.

Dilatometer tests in a Leda clay crust

The dilatometer test results have been lately applied in foundation design for prediction of settlement and bearing capacity problems. The equipment, its calibration, test procedures and test data interpretation are simple. These advantages seem to explain the increasing use of the dilatometer (DMT) test as a routine technique for subsoil investigation. The DMT test boreholes were carried out on the grounds of the National Research Council (NRC) in Ottawa. Several test results based on laboratory, and other in situ tests available in the literature for the Leda clay deposit in Ottawa area were used to provide correlations between geotechnical properties and soil index parameters as proposed by Marchetti (1980). More appropriated relationships, even though preliminaries, are presented for the crust layer.

Automatic absolute orientation of scanned aerial photographs

Image orientation is a basic problem in Digital Photogrammetry. While interior and relative orientations were succesfully automated, the same can not be said about absolute orientation. This process can be automated by using an approach based on relational matching and a heuristic that uses the analytical relation between straight features in the object space and its homologous in the image space. A build-in self-diagnosis is also used in this method, that is based on the implementation of data snooping statistic test in the process of spatial resection, using the Iterated Extended Kalman Filtering (IEKF). The aim of this paper is to present the basic principles of the proposed approach and results based on real data.

The influence of the physigraphic and geologic condition aspects on the environmental degradation in the city of Guaratingueta

The present paper deals with environmental degradation in the city of Guaratingueta, Brazil; as a result of disordered urban settlement and development. Three site areas in the city resting on different geologic units were selected for the analyses, i.e.: precambrian rocks, tertiary sedimentary basin, and recent quaternary soil deposits. It has been found that geological and geotechnical aspects are fundamental to form the basis for environmental preservation and urban planning.

Energy efficiency for standard penetration tests

The need for standardization of the measured blow count number N-spt into a normalized reference energy value is now fully recognized. The present paper extends the existing theoretical approach using the wave propagation theory as framework and introduces an analysis for large displacements enabling the influence of rod length in the measured N-spt values to be quantified. The study is based on both calibration chamber and field tests. Energy measurements are monitored in two different positions: below the anvil and above the sampler. Both experimental and numerical results demonstrate that whereas the energy delivered into the rod stem is expressed as a ratio of the theoretical free-fall energy of the hammer, the effective sampler energy is a function of the hammer height of fall, sampler permanent penetration, and weight of both hammer and rods. Influence of rod length is twofold and produces opposite effects: wave energy losses increase with increasing rod length and in a long rod composition the gain in potential energy from rod weight is significant and may partially compensate measured energy losses. Based on this revised approach, an analytical solution is proposed to calculate the energy delivered to the sampler and efficiency coefficients are suggested to account for energy losses during the energy transference process.

This paper describes the experiences of long-distance courses, it focused on the continuing education of basic education teachers in all Brazilian territory. Such courses were offered by CECEMCA (Center for Continuing Education in Mathematics Education, Science and Environment), linked to the Universidade Estadual Paulista Julio de Mesquita Filho - Campus de Rio Claro during 15/01/2009 to 30/11/2009. The subjects report to the theme of Education, Geography and Environment, it was organized in four courses: "Introduction to Cartography," Environment and climate change - thinking a new paradigm of sustainable green planet "," Remote Sensing in environmental studies Environment "and" Methodological Alternatives for Inclusive Classroom: Experimenting with visual and hearing impairments". So, we show here, the feasibility and importance of distance learning tools for education, specifically teacher training, based on the results obtained in these courses.

Methodological contributions towards the study of health care production: lessons from a research study on barriers and access in mental health

This article presents methodological contributions and a conceptual innovation for thinking about the production of health care, stemming from a study on access and barriers in mental health carried out in the municipality of Campinas (São Paulo, Brazil). The study used a cartographic approach and, after an initial identification of the most complex cases (on the part of the teams of workers), adopted the users as guides to explore the different levels of production of their lives and to evaluate the possibility of forming a network of existential connections that produce life as a fundamental analyzer of access or barriers to care.
