Soil science has sought to develop better techniques for the classification of soils, one of which is the use of remote sensing applications. The use of ground sensors to obtain soil spectral data has enabled the characterization of these data and the advancement of techniques for the quantification of soil attributes. In order to do this, the creation of a soil spectral library is necessary. A spectral library should be representative of the variability of the soils in a region. The objective of this study was to create a spectral library of distinct soils from several agricultural regions of Brazil. Spectral data were collected (using a Fieldspec sensor, 350-2,500 nm) for the horizons of 223 soil profiles from the regions of Matão, Paraguaçu Paulista, Andradina, Ipaussu, Mirandópolis, Piracicaba, São Carlos, Araraquara, Guararapes, Valparaíso (SP); Naviraí, Maracajú, Rio Brilhante, Três Lagoas (MS); Goianésia (GO); and Uberaba and Lagoa da Prata (MG). A Principal Component Analysis (PCA) of the data was then performed and a graphic representation of the spectral curve was created for each profile. The reflectance intensity of the curves was principally influenced by the levels of Fe2O3, clay, organic matter and the presence of opaque minerals. There was no change in the spectral curves in the horizons of the Latossolos, Nitossolos, and Neossolos Quartzarênicos. Argissolos had superficial horizon curves with the greatest intensity of reflection above 2,200 nm. Cambissolos and Neossolos Litólicos had curves with greater reflectance intensity in poorly developed horizons. Gleisols showed a convex curve in the region of 350-400 nm. The PCA was able to separate different data collection areas according to the region of source material. Principal component one (PC1) was correlated with the intensity of reflectance samples and PC2 with the slope between the visible and infrared samples. The use of the Spectral Library as an indicator of possible soil classes proved to be an important tool in profile classification.

This paper addresses the problem of multilingual digital libraries. The motivation for a such a digital library comes from the diversity of languages of the Internet users as well as the diversity of content authors, from e-book authors to writers of courseware. The basic definitions of such a system, the specifications of its functionality and the identification of the items it holds are discussed. The impact of multilinguism in each of the former aspects is presented. A case study of a multilingual digital library - in the Maxwell System in PUC-Rio - is described in the last sections. Its main characteristics are described and the current status of its digital library is shown.

Este estudo foi desenvolvido em um hospital privado, no Rio de Janeiro, com o intuito de demonstrar o valor de uma biblioteca médica digital, como ferramenta de suporte para fundamentação científica das condutas assistenciais adotadas pela equipe médica, que resultaram em glosas técnicas e perda de faturamento para a instituição. Para isso, por meio do método revisão integrativa, foi coletada a literatura clínica referente às glosas, ocorridas durante o período de janeiro a setembro de 2014, e analisada sob a perspectiva do modelo conceitual apresentado pela Cochrane (LEFEBVRE et al., 2011) que identifica o nível da evidência científica e estabelece o seu grau de recomendação para a prática clínica. Durante a análise de conteúdo, considerando as técnicas propostas por Bardin (1977), foram identificadas as evidências científicas que conferem valor à prática assistencial, conforme proposto pelo modelo conceitual. Além disso, o valor dos itens glosados foi incluído na análise dos resultados, reforçando a tendência do estudo para a validação do modelo conceitual que recomenda a prática clínica baseada em evidências científicas para geração de resultados mais efetivos e de melhor custo/benefício na saúde. Com base nos achados, são discutidas as implicações teóricas e práticas, assim como sugestões para futuros estudos sobre o tema.
