Manifestações de obstáculos gnosiológicos para a seleção de conteúdos na implementação de um currículo crítico em ciências
(Universidade Federal de São Carlos, 2014-02-13) Alves, Anaí Helena Basso; Silva, Antonio Fernando Gouvêa da; https://lattes.cnpq.br/9621931288117213; https://lattes.cnpq.br/5143745113412522
From literature searches and semi - structured interviews with educators, science, high school, the state education Sorocaba - SP network, we sought to characterize possible manifestations of gnosiological obstacles that constitute a limit for a content selection in implementation of a critical science curriculum. For the critical science curriculum implementation, participation of the subjects of the school community in building and curriculum implementation review in science, standalone and conscientious manner, collective, socially committed and dialogical, become sociocultural, political and epistemological fundamental requirements. From references to Bachelard, Fleck, and Freire, we sought to deepen understanding about the manifestations of gnosiological obstacles in the school context. To that end, we explored some possible manifestations , such as fear of freedom (Fromm) for the selection of content, the denial of epistemological discontinuity (Delizoicov) for the genesis of knowledge, the claim of scientific truth (PINTO) and epistemological arrogance (Freire). Then we were given some considerations about the methodology of qualitative research that guided data collection. And finally, we systematize possible obstacles gnosiological assumed as for theoretical work, in that educators share showed naive conceptions of knowledge, science and education, for example, the vision of continuous knowledge, cumulative and linear, the content- of the curriculum, the vision of universal and common knowledge to all, denying the specifics of the community, among other visions that can be considered as limits for the implementation of a critical science curriculum. As a proposal for overcoming the obstacles shared by educators, are suggested to be organized new models of teacher education to consider the limits, especially regarding the understanding of curriculum development and selection of contents in critical curricular context. Take practical problem-solving and dialogical freireanas, to question entrenched and culturally shared beliefs can be constituted as alternatives and possibilities for overcoming and mobilization of the conceptions of teachers, pointing to a new model of teaching-learning, critical and committed to a humanizing education and emancipation of the socially oppressed subjects.

The investigation of land use changes as a result of pressure from anthropogenic processes, is a tool for establishing correlations between spatial and temporal patterns and ecological processes of the landscape, being adequate for management of the surrounding protected areas. The Conservation Units surrounding_s in Brazil require measures that complement conservation strategies adopted only for the limits of the protected areas. The bu_er zones of conservation units surrounding has not yet received the attention needed to meet the objectives of in situ conservation. The general aim of this work was to analyze and quantify the land use dynamic and fragmentation process of natural vegetation, analyze the ecological sustainability and delineate scenarios for biodiversity conservation in the Passo Fundo National Forest surrounding, in the period 1986 to 2011, in order to generate information to management and implementation of conservation measures. Land use maps were made from Landsat image 5 of 12/09/1986, 08/09/1997 and 01/09/2011, orbit 222, 79 and 80 points. The mapping was done by visual classi_cation in software Mapinfo 10.0. The natural vegetation fragmentation process in 1986, 1997 and 2011 was analyzed from the elaboration of thematic maps of natural vegetation, and application of the landscape metrics in software Fragstats 4.1 (number of fragments, mean area of the fragments, proportion of natural area in the landscape, and degrees of isolation /connectivity and complexity of shapes of the patches). Ecological sustainability was assessed by using naturalness / urbanity (IB), environmental quality of fragments of natural vegetation (IQABIO) and environmental vulnerability (VAT-P) indicators, whose equations were calculated using the Idrisi software Selva. With environmental quality and naturalness and natural vegetation indicators were selected fragments of the study area with higher naturalness and quality to delineate a biodiversity conservation scenario for the Flona-PF surrounding. The results showed that the direct and indirect drivers of landscape change are respectively the agricultural activities, urbanization and conict with the local indigenous community. From 1986 to 2011 there was a reduction in the areas occupied by human activities and an increase in the proportion of natural areas. The average size of fragments or patches of natural vegetation increased, and the isolation distance between the fragments decreased in 2011, compared to previous periods (1986 and 1997). The indicators (IB, IQABIO and VAT-P) pointed Flona-PF and neighboring fragments as the areas with higher environmental quality, naturalness and less vulnerability. However, the vulnerability analysis (VAT-P) take into account only the direct forces changes of landscape changes disregarding the indirect forces as the demand of land by the local indigenous community, which can cause changes in this conservation area, including change of category. The results show a tendency to decrease the direct forces of landscape change for the Flona-PF surrounding during 1986 to 2011.
Metodologias, instrumentos e interfaces de organização de fotografias na web: uma análise na perspectiva do Patrimônio Cultural Rural Paulista
(Universidade Federal de São Carlos, 2014-02-13) Silveira, Letícia Reis da; Gracioso, Luciana de Souza; https://lattes.cnpq.br/4898201916360294; https://lattes.cnpq.br/2964936440944082
The present days are characterized by the increasingly volume of information available on different kinds of media, and proportionally by the increasingly need to think, create and evaluate methodologies and tools that deal with the processing and dissemination of relevant information to users' satisfaction. In this context, the objective of this research was to identify in what proportion some of the online systems available for organizing and retrieving photos include in their search interfaces for the user some of the major categories related to thematic processing of photographs, as surveyed and reported in the literature of Information Science. Among these systems, special attention was given to the analysis of Virtual Memory, software that has been developed within the project "Criteria and Methodologies for conducting an inventory for Rural Heritage", funded by FAPESP and coordinated by Professor Luzia Fernandes Sigoli Costa, from Federal University of São Carlos, which proposes the construction of a standard description of informational goods for the software. Methodologically, this paper is configured as an exploratory, bibliographic and documentary research, also developing actions of intervention research and using participant observation to collect data. The results indicate that relevant practices have been developed for online information systems regarding the organization of photographs and confirmation of the use of resources for social indexing as means of organization and information retrieval. Finally, it is hoped that this study can contribute to CTS field presenting what scientific literature has to offer regarding image organization, assisting in future research and suggesting ways for the construction or improvement of technological tools that give support to the imagery processing and dissemination of information to society, such as the Virtual Memory software, contributing to the process of memory and heritage of humanity.
