Despite the current Environmental Legislation resolution, concerning the protection of the Permanent Preservation Areas (PPA), be quite rigid, in practice, is observed noncompliance with the minimum limits of protection, especially in urban areas where, historically, the urbanization processes have been executed without compliance with the minimum standards of urban and environmental planning. Given the above, the present study aimed to analyze the urban sprawl evolution at the Olinda stream APP, located in the city of Rio Claro - SP. By means of the visual interpretation of aerial photographs in the GIS/ARCGIS environment, thematic maps of the urban sprawl of the years 1972, 1995 and 2010, as well as the Olinda Stream APP surroundings, were prepared. From the maps, it was possible to measure the occupation density for each scenario and indicate from which period the urbanization process has intensified. It was also possible to quantify the loss of vegetation area and indicate the major environmental problems in the basin of the Olinda stream. Therefore, the development of this research shows its importance, considering that its results can support the public administration, assisting in proper planning of land use and occupation in urban watersheds

Ce travail montre une étude sur l’oralité et l’interculturalité présentes dans l’ouvrage Le chercheur d’or, de J.-M. G. Le Clézio. Les sources des principaux mythes et légendes introduits dans le récit seront mis en évidence, afin de faire ressortir la façon par laquelle l’auteur propose un panorama culturel avec plusieurs faces, en mélangeant, d’une manière homogène, des éléments différents par rapport à ses origines. Ainsi, nous décrirons les éléments essentiels du récit pour que nous puissions comprendre comment Le Clézio transforme son texte en une mosaïque ethno-culturelle, dont l’aspect poliphonique a une grande importance pour que l’interculturalité proposée et l’unité du récit soient atteintes

The need for unmanned aerial vehicle (UAV) is a Brazilian reality in the worlds agricultural, once they have models penetrating the market with agrictural purpose. After processing, the images collected by a UAV can generate a mosaic of the study area. For making and georeferencing the mosaic, can be deployed or not ground control points. Thus, the study aimed to compare a mosaic with ground control points and without ground control points generated from images collected by a UAV used primarily for agricultural purposes. The results showed that the quality in the determination of areas and perimeters no presented significant difference with or without the use of ground control points. The mosaic generated without ground control points obtained an average error of 23.7% of the pixel size; with ground control points, the average error was 10.6%, providing an improvement of approximately 50%. Planimetric and altimetric errors, with respect to the ground control points, for the controlled mosaic, reached the order of decimeters, with planimetric accuracy of 12.8 cm, a result considered satisfactory taking into account mainly the purpose of assessed UAV

O presente trabalho tem como objetivo descrever a estrutura fitossociológica do estrato herbáceo, de diferentes manchas que definem o mosaico da vegetação de um trecho do Ribeirão Claro e seu afluente Jardim Bandeirantes, analisando a diversidade das comunidades no tempo e no espaço, a dominância e a distribuição das espécies, estabelecendo relações com variáveis ambientais edáficas (umidade, pH e teor de matéria orgânica) e microclimáticas (luminosidade, cobertura de dossel e declividade), a fim de estudar a estrutura, composição e os processos sucessionais desta fitocenose. Foram definidas 13 manchas de vegetação como foco de estudo, em cada uma foram dispostas 6 parcelas de 5x5m perfazendo uma extensão de 30 m perpendicularmente ao rio. No interior das parcelas foram levantadas todas as formas de vida vegetais abaixo de 1,5m de altura, aplicando-se um método de avaliação de cobertura (método do toque), onde a amostragem foi realizada em intervalos de 0,5m. Os indivíduos foram amostrados com indicação do seu hábito e classificação taxonômica. As quantificações foram realizadas tanto no período chuvoso quanto no período seco, com a finalidade de entender a dinâmica sazonal dessa comunidade. A comunidade estudada apresentou variação em sua composição e estrutura no que se refere às estações seca e chuvosa. Os parâmetros ambientais analisados mostraram uma heterogeneidade física nas fisionomias descritas, o que pode estar contribuindo para a diferenciação na distribuição das espécies amostradas em cada fisionomia. Com base no inventário realizado, envolvendo a vegetação marginal do trecho estudado do Ribeirão Claro e seu tributário Jardim Bandeirantes, em duas estações distintas, os dados mostraram maiores variações da cobertura herbácea nas fitocenoses em estágios sucessionais mais avançados...

Teaching cases are records, through written narratives, of an academic episode or incident, they appear in educational scenery as a rich strategy not only for the teacher's conformation but also for their investigation. The bibliography shows that young students are still not very much investigated and it contributes to the establishment of negative images of this social subject. In this sense, the objective of this work is to analyze the stories and episodes, called teaching cases, in narrative style, written by students from High School about their physical education classes. The participants of this study are High School students from two public schools from two cities in the countryside of São Paulo state. The researcher stayed in the schools for nine months and in this meantime she made contact with the students, asking, for the ones who showed interest, the construction of teaching cases. For this interested students, the researcher explained researcher explained what teaching cases are, as well as, she presented a template to guide them in the production. At the end of this process, twenty teaching cases were delivered to the researcher. They were analyzed under the qualitative approach, valuing the expressive wealth in the narratives, complemented by the interviews with the authors. Inset the mosaic of narratives and interviews, showing a variety of experiences and possibilities of distance and approximation of the students to the physical education classes, we can indicate that from the 20 cases, only one was set as a total distance from the physical education classes (this is the student's situation since she was in the second grade from elementary school). Mentioning the positive experiences and the approximation to the physical education classes, the association of teaching cases and interviews showed that seven students lived the context and until today present an affective proximity to the classes. These evidences can help...
