The inadequate soil use is an aggravating factor of the environmental degradation and ecological unbalance. The analysis of the use and covering of the soil, by information of Remote Sensing, constitutes a technique of great usefulness to the planning and administration of the ordered occupation and rational of the physical middle, besides making possible to evaluate and to monitor the preservation of areas of natural vegetation. This work sought to evaluate the conflicts of soil use in permanent preservation areas (PPA) in Stream Comur watershed - Botucatu (SP) through Geographical Information System and satellite image of 2009. The study area is located among the geographical coordinates 48o 23’ 04” to 48o 25’ 54” of longitude WGr. and 22o 44’ 42” to 22o 48” 12” of latitude S with an area of 1,719.6 ha. The results allowed to verify that the geoprocessing techniques were of fundamental importance in the identification of the areas of soil use, of APP and of conflicts among use and PPA where it leaves of the areas of APP is being used inadequately. In terms of environmental sustainability, it can be deduced that the watershed is very unfavorable, once it presents 70.67% of area used inadequately with sugarcane and pasture.

Evaluation and adequacy of land occupation in Permanent Preservation Areas (PPAs) are important to ensure quantity and quality of water and local biodiversity. The objective of the study was mapping PPAs according to the Brazilian Forest Code and quantifying land cover and use, establishing the conflict of PPAs occupation in the Ribeirão Lavapés sub watershed. The area is 11,154.58 ha, and is located in Botucatu city, Midwestern region of São Paulo state. For this reason, geoprocessing tools, such as Remote Sensing and the Geographic Information System (SIG) were used. The dominant classes of land use and cover were the Urban Zone in Reverse Cuesta, 4,394.27 ha (39.39%) and Annual Crops in the Peripheral Depression, 3,670.89 ha (39.39%). The mapped area of native forest vegetal cover in the sub watershed was of 1,109.70 ha. Regarding the mapping of PPAs, considering the total area of 1,721.80 ha, a total of 532.15 ha (30.91%) are covered by Riparian Forest and 1,189.65 ha (69.09%) had no native riparian vegetation, therefore, requiring its reforestation.

This article focuses on some aspects of the agrarian history of Soledade, a town in the north of the state of Rio Grande do Sul, southern Brazil. Our aim is to understand how this area was in many ways affected by the Land Law of 1850, particularly in economic and social terms. Population growth, arrival of European immigrants and increasing privatization of the commons contributed for the increasing of land prices in the region during the second half of the 19 th century. Understanding this situation as a great opportunity to make money, some landowners, directly or through a colonization company, allotted and sold the land they had previously acquired through the Land Law of 1850

Vivemos um período de transformações políticas, econômicas, sociais e culturais que, a todo instante, nos impõe desafios. Neste contexto, nas últimas décadas, o uso da tecnologia tem sido ampliado na realização de diversas atividades cotidianas, na divulgação de informações, na comunicação, como forma de expressão e organização da sociedade. A escola, enquanto instituição social, precisa reconhecer esta nova realidade, esta diferente possibilidade de aquisição e transformação de saber, para que possa intervir, ressignificar e redirecionar sua ação, a fim de atender as demandas de seu tempo. O objetivo geral desta pesquisa, a partir da apresentação e análise de experiências realizadas com o uso de Tecnologias da Informação e Conhecimento, é o de refletir sobre como inserir estas ferramentas no processo de ensinar e aprender na escola a partir da visão de professores e alunos, visando a formação integral do educando. Deste modo, no desenvolvimento, entendemos como necessário conhecer e considerar o contexto histórico, bem como as perspectivas relacionadas a escola e seus protagonistas (professores e estudantes) na chamada Sociedade da Informação e do Conhecimento. Ressaltamos a importância do docente (sua formação) e seu papel de mediador nos processos de aprendizagem, assim como a recepção à tecnologia, observando função e espaço de atuação desta. Destacamos experiências com a utilização de TDIC, realizada por professores e alunos, como a produção de game, revistas científicas, escrita de histórias, produções artísticas, blogs, vlogs, discussões em grupos presentes em redes sociais. A metodologia utilizada nesta pesquisa é qualitativa, na modalidade de pesquisa-ação e narrativa, em função do envolvimento com o grupo e com as atividades desenvolvidas, nas quais os participantes compartilham com o pesquisador suas histórias pessoais e de aprendizagem relacionadas às ações ou às atividades que realiza, fornecendo informações e indícios relevantes sobre o seu processo de formação ao longo do tempo. A revisão de literatura foi realizada por meio de análise bibliográfica e documental em livros, teses, dissertações, periódicos específicos sobre o assunto, além de artigos publicados na Internet. A coleta de dados foi realizada a partir de conversas informais, entrevistas semiestruturadas e filmagem dos relatos. A análise foi realizada a partir da abordagem hermenêutico-fenomenológica, que busca descrever e interpretar fenômenos da experiência humana, a fim de investigar a essência por meio da identificação de temas. Os resultados apontam para a necessidade e possibilidade da ampliação da utilização de TDIC como recurso no processo de ensino e aprendizagem, por meio de formação, diálogo, interação, intencionalidade, expectativas, esperança e seus desdobramentos.

A crescente demanda por recursos naturais e a conseqüente perda de qualidade e quantidade dos mesmos, indica a necessidade do desenvolvimento de alternativas, nas diversas áreas do conhecimento e das atividades humanas. No caso dos agroecossistemas, as práticas convencionais provocaram ao longo do tempo a degradação do solo e dos recursos hídricos, a perda da biodiversidade e a desestruturação dos ecossistemas, que culminaram em desequilíbrios globais de balanço hídrico e temperatura. O presente estudo visa analisar o potencial de utilização de Sistemas Agroflorestais (SAFs). SAFs são práticas de manejo da terra há muito tempo conhecidas, que associam, deliberadamente, árvores com culturas agrícolas temporárias, permanentes e/ou animais simultaneamente ou sucedendo-se temporalmente no espaço; obtendo os benefícios de proteção ambiental e de produção proporcionados pelas árvores. Para a realização do estudo foram utilizadas as bases cartográficas digitalizadas das características ambientais (solo, topografia, hidrologia e clima) do município e as mesmas foram sobrepostas através do Sistema de Informação Geográfica (SIG). As características ambientais de São Carlos, indicam a necessidade da adoção de sistemas de produção sustentáveis, capazes de conservar a qualidade e a quantidade do solo e dos recursos hídricos disponíveis, bem como sua biodiversidade, por isso apresenta grande aptidão para a utilização dos SAFs e uma ampla variedade de espécies com potencial de uso. A prioridade de adoção de SAFs é para áreas degradadas e subutilizadas, áreas de preservação ambiental e adjacentes, reservas legais e áreas suscetíveis à erosão. Sugere-se novos estudos, em campo, para comprovação dos resultados teóricos obtidos.

This dissertation describes the construction of a alternative didactic incorporating a historical approach with the use of the Roman abacus for teaching multiplication to students of 2nd year of elementary school, through activities ranging from the representation of numbers to multiplying with the Roman abacus, for learning the multiplication algorithm. Qualitative research was used as a methodological approach since the research object fits the goals of this research mode. Concerning the procedures, the research can be seen as a teaching experiment developed within the school environment. The instruments used for data collection were: observation, logbook, questionnaires, interviews and document analysis. The processing and analysis of data collected through the activities were classified and quantified in tables for easy viewing, interpretation, understanding, analysis of data and then transposed to charts. The analysis confirmed the research objectives and contributed to indicate the pedagogical use of the Roman abacus for teaching multiplication algorithm through several activities. Thus, it can be considered that this educational product will have important contributions for the teaching of this mathematical content, in Basic Education, particularly regarding to the multiplication process

In this work, we present our understanding about the article of Aksoy [1], which uses Markov chains to model the flow of intermittent rivers. Then, we executed an application of his model in order to generate data for intermittent streamflows, based on a data set of Brazilian streams. After that, we build a hidden Markov model as a proposed new approach to the problem of simulation of such flows. We used the Gamma distribution to simulate the increases and decreases in river flows, along with a two-state Markov chain. The motivation for us to use a hidden Markov model comes from the possibility of obtaining the same information that the Aksoy’s model provides, but using a single tool capable of treating the problem as a whole, and not through multiple independent processes

Data Visualization is widely used to facilitate the comprehension of information and find relationships between data. One of the most widely used techniques for multivariate data (4 or more variables) visualization is the 2D scatterplot. This technique associates each data item to a visual mark in the following way: two variables are mapped to Cartesian coordinates so that a visual mark can be placed on the Cartesian plane; the others variables are mapped gradually to visual properties of the mark, such as size, color, shape, among others. As the number of variables to be visualized increases, the amount of visual properties associated to the mark increases as well. As a result, the complexity of the final visualization is higher. However, increasing the complexity of the visualization does not necessarily implies a better visualization and, sometimes, it provides an inverse situation, producing a visually polluted and confusing visualization—this problem is called visual properties overload. This work aims to investigate whether it is possible to work around the overload of the visual channel and improve insight about multivariate data visualized through a modification in the 2D scatterplot technique. In this modification, we map the variables from data items to multisensoriy marks. These marks are composed not only by visual properties, but haptic properties, such as vibration, viscosity and elastic resistance, as well. We believed that this approach could ease the insight process, through the transposition of properties from the visual channel to the haptic channel. The hypothesis was verified through experiments, in which we have analyzed (a) the accuracy of the answers; (b) response time; and (c) the grade of personal satisfaction with the proposed approach. However, the hypothesis was not validated. The results suggest that there is an equivalence between the investigated visual and haptic properties in all analyzed aspects, though in strictly numeric terms the multisensory visualization achieved better results in response time and personal satisfaction.

Shaping the Luso-Brazilian space in Portuguese America was through constant conflicts between different individuals and institutions. Regarding to land ownership, such conflicts were aggravated, depending on the individuals involved and their context. The captaincy of Rio Grande, there is conflict over land ownership Cidade dos Veados and Olho d' Água Azul and its stakeholders: priests of the Society of missionaries of the village Guajiru; indian mission Guajiru; and members of Carneiro da Cunha family. In 1725, the jesuit mission Guajiru requested a league of land at a place called Cidade dos Veados for the indians of his mission claiming that the land that the mission had was not sufficient for the subsistence of the same. In 1727, priest requested another league of land in place Olho d'Água Azul, stating that the mission had more than 192 couples. Both lands were properly required for the mission guajiru. however, in 1760, with the changes imposed by the indian directorate ombudsman responsible for investigating indigenous possessions realized that the indians did not occupy the two lands requested in the 1720s , due to the fact João Carneiro da Cunha has taken possession of the same. As a result, the impasse over land are ligth. This conflict over land ownership Cidade dos Veados and Olho d'Água Azul, we intend to highlight in particular the motivations and mindsets about possessory property of each party involved. We seek to understand the motivations of each group involved allowed the use of specific strategies and set out to try to take possession of the lands of the Cidade dos Veados e Olho d'Água Azul
