A mediação da informação aliada ao uso das tecnologias da informação e comunicação em uma biblioteca escolar

Introduction: This paper presents preliminary results of the research project "Information access: actions and strategies of the Chamber of Deputies to meet 12.527/2011 Law”. Finally some considerations about the implementation of the Law within the Chamber of Deputies are presented. Objectives: Discuss the matter of public information access after the new Brazilian information access law and his relationship between the theories information policy, information regime and informational state. Methodology: Bibliographic research about several theoretical topics related to information access were raised, for example: the concept of information, information policy, informational state, information regime, electronic government and information asymmetry. Results: The preliminaries data shows a convergence of information policies from many countries, for example, Finland, Canada and South Africa, to a same point, which indicates an increase of transparency and a bigger active disclosure of information public. Conclusion: In Brazilian case, in the relationship between State and citizen, the new information access law means a materialization paradigm change or the concretization de other information regime. The sanction of this law can be interpreted as another step to increase the transparency and the affirmation of democratic relationship between State and society.

Processos de gestão da informação: tratamento, recuperação e uso da informação no mercado de capitais

In the capital market the information are used as subsidies for the decision making of investors, among the main highlights are the economic, political, accounting and relating nature to the financial results of companies which have stocks traded at Stock Exchanges. In this perspective, it is essential that the agents involved especially brokerage companies establish management processes that contain a set of criteria for the organization and treatment of information collected in newspapers, news agencies and the companies that trade in stocks. Thus, it is essential to establish rigor in relation to recovery mechanisms of such information, which requires more than technology, because actions are necessary that will propitiate the informational content are made available with consistency, clarity and trustworthiness, so as that users can retrieve them in a timely manner. Furthermore, those processes should provide the efficient use of the information retrieved by users, so that they can use them aiming to subsidize the decisions of sale or purchase shares. Considering that the information systems are responsible for the information dissemination in the framework of capital market, it is necessary to present requisites that contemplate the set organization, treatment, retrieval and use of information. That way, we sought to evidence in this paper these issues, utilizing as a premise the elements proposed by Guimarães (2003) from the perspective of the information environment of a values brokerage companies reflecting through the model used, how these companies realize their work considering the dimensions of the documentary analysis, informational treatment, and the instruments for retrieval and use of information.

Web colaborativa: inovação na criação, proteção e uso legal de informação

In the contemporary world, the Internet enables the development of a Collaborative Web where the decentralization and sharing of information and knowledge generate new cultural configurations of increasing representation in informational flows. In this environment, collaboration and remix practices are covered by a legislation established for another context, and an imbalance is created between what is provided by the technology and what is established by Copyright. Therefore, it is necessary to address, under the perspective of the third time in Information Science, contemporary issues concerning creation, recreation, use, reuse, sharing and dissemination of intellectual content under the legislation which regulates them. This article seeks to highlight the dilemma that contemporaneity is experiencing and how important is for both society as a whole and specially the professional of Information Science to know the legal conditions for the processes of generating, processing, using, recovering and, especially, re-using information on the Web at a larger scale. The Creative Commons licenses are emerging alternatives that offer individuals options to become not only users but also holders and creators of intellectual content under legal conditions.

Análise da dinâmica de ocupação e uso das terras e suas implicações no sistema morfohidrográfico da Bacia do Ribeirão Bonito-SP

Os sistemas ambientais são compostos por elementos e atributos que atuam em sua dinâmica, os quais, ao longo de um dado período de tempo, podem responder às condições naturais ou às imposições antrópicas, sendo que estas últimas podem desencadear modificações no seu equilíbrio natural. Neste contexto, o objetivo principal do trabalho proposto foi identificar e analisar as alterações na dinâmica de ocupação e uso das terras e sua interferência nas características naturais da bacia do Ribeirão Bonito – SP, com ênfase à geomorfologia e hidrografia. A área em questão situa-se junto à baixa bacia do Rio Piracicaba, no Estado de São Paulo, numa área de transição entre a Depressão Periférica Paulista e as Cuestas Basálticas. Para a consolidação do objetivo proposto foram utilizados os seguintes procedimentos metodológicos: revisão de literatura referente à temática adotada; caracterização do meio físico e do processo de ocupação da área em estudo; elaboração de mapas geomorfológicos de dois cenários (1962 e 2007) de acordo com as metodologias de Tricart (1965) e Verstappen; Zuidan (1975), adaptados por Cunha (2001); elaboração de mapas de ocupação e uso das terras dos dois períodos (1962 e 2007) utilizando o sistema de classificação do IBGE (2006b) e trabalhos de campo. Para manuseio dos dados e posterior análise dos mesmos, foi utilizada a idéia de sistema ambiental, que se fundamenta na teoria dos sistemas gerais, aplicada a Geografia. Findados os levantamentos, observou-se que o aumento do nível de base local com conseqüente retomada erosiva, assim como a intensa ocupação das terras pela cultura da cana-de-açúcar, foram fatores que condicionaram as alterações geomorfológicas locais, expressas principalmente pela dinâmica erosiva e processos de denudação

Uso da calculadora nas aulas de Matemática: possibilidades e percepção de licenciandos e professores

The objective of this work is to analyze teaching situations with the use of calculator inside classroom aiming to understand its function and potential to the learning of Mathematics. A survey was carried out about the students and teachers’ conceptions concerning the use of calculator as an auxiliary tool in the learning of Math . The first part of the research is based by means of official documents (Parâmetros Curriculares Nacionais (PCN) , Proposta Curricular do Estado de São Paulo, Guia do Programa Nacional do Livro Didático (PNLD)) , researches and other publications , characterizing by a bibliographic study. The survey with the participants— Math students and teachers acting in public or private schools of São Paulo state— was done through a questionnaire and interviews . The results show that most part of interviewed people are in favor of the use of calculator in the classroom . However , a big part of this number still consider it only as a tool to speed calculations with high numbers or decimals . It was verified that teachers who have recently graduated and have taught for a short period of time accept and comprehend the role of calculator more easily in some activities and consider it as an useful and auxiliary tool to the students’ learning

Uso de células-tronco para o tratamento de tendinite em eqüinos

Brazil has the fourth largest horse herd in the world, this is due the recognition and appreciation that the different equestrian games are having within the country. Injuries of the tendon, especially in the digital flexor tendon, are the main cause of athletic life reduction among horses. The treatment of tendinitis in horses seeks full recovery of the damage tissue reestablishing the function previously lost, however conventional treatments have proven to be ineffective when considered the quality of the scar tissue and the rate of recurrence. Due to this, the use of adult stem cells to the treatment of musculoskeletal injuries of horses has been studied for some time. This method of treatment consists of aspiration of bone marrow or removal of subcutaneous fat tissue and implantation of these cells in the injured tissue. After obtaining the bone marrow the implantation can be performed with total bone marrow, with the mononuclear fraction of MSC or with cells cultured in vitro. From the fat tissue is used the stromal vascular fraction obtained by collagenase digestion, followed or not by cell culture. According to some studies, cell therapy with material obtained from bone marrow or adipose tissue has shown to be viable, given that these materials are abundant in repair components such as mesenchymal stem cells (MSC), growth factors and other components of the collagen matrix. Several studies using both types of cells have shown great potential and promising clinical results. However, knowledge of the biology and characterization of these cells remain largely unknown, and therefore is needed great care and caution when using stem cells for the treatment of musculoskeletal disorders in horses

Uso sustentável da biodiversidade brasileira: prospecção químico-farmacológica em plantas superiores: estudo químico de Astronium graveolens (Anacardiaceae)

O gênero Astronium, pertencente à família Anacardiaceae, é composto por cerca de 35 espécies, sendo típico das regiões norte e nordeste do Brasil. De acordo com a literatura, apenas a espécie Astronium urundeuva foi investigada sob o ponto de vista farmacológico, sendo detectada atividades antiulcerogênica , antiinflamatória e efeitos no trânsito gastrintestinal . Nas espécies A. graveolens e A. fraxinifolium foram avaliados somente os óleos essenciais, sendo que em A. graveolens um desses compostos voláteis mostrou atividade repelente a insetos. Desta forma, percebe-se que a investigação desse importante gênero vegetal ainda é incipiente. Estudos preliminares com o extrato em acetato de etila das folhas de A. graveolens mostraram grande concentração de compostos fenólicos, como derivados de ácido gálico e flavonoides, os quais estão descritos na literatura em geral como substâncias antioxidantes em potencial. As propriedades antioxidantes de diversas substâncias são alvo de interesse nos dias de hoje principalmente por estarem relacionadas à terapêutica de doenças degenerativas. Com o objetivo de dar continuidade aos estudos das espécies citadas, foram utilizadas neste trabalho técnicas de cromatografia como análise por cromatografia líquida de alta eficiência para o estudo do perfil químico de Astronium graveolens, separação e identificação de metabólitos secundários. Baseado na literatura e na comparação com padrões, os espectros de ultravioleta observados, indicaram que os extratos em acetato de etila da espécie em estudo são compostos por substâncias derivadas do ácido gálico, derivadas do ácido cafeoilquínico e também por flavonóides. A substância Ag1 foi identificada a partir de experimentos de comparação por CLAE usando banco de padrões, após verificação de similaridade entre tempo de retenção e máximo de absorção...

Uso de pré-dicas informacionais em tarefas de alcance a um alvo: um estudo desenvolvimental

Alterações nas competências motoras da infância até a idade adulta envolvem vários aspectos do comportamento humano. Na perspectiva cognitiva, indivíduos planejam ações motoras através de três estágios seqüenciais e interdependentes: identificação do estímulo, seleção da resposta e programação da resposta. Após tais estágios que correspondem à preparação motora, o tempo de execução inicia. A partir do sinal imperativo, o executante seleciona e programa a ação. Se o estímulo é apresentado consistentemente da mesma forma, então a resposta a tal estímulo será mais rápida, comparada a uma situação em que o estímulo é apresentado de forma diferente do esperado. Neste último caso, o executante necessitará reprogramar sua ação motora e consequentemente levará mais tempo para planejá-la. O objetivo deste estudo foi examinar o efeito de informação prévia (i.e., dica) na preparação e execução de tarefa de alcance a um alvo por crianças de 6, 8, e 10 anos e adultos. Informação prévia era fornecida em três condições experimentais: correta, incorreta e neutra. As variáveis dependentes foram: tempo de reação (TR), tempo de movimento (TM), tempo de desaceleração (TD), índice de retidão (IR) e número de unidades de movimento (UnM). Com respeito à preparação da ação motora, os resultados indicaram que o TR diminuiu com a idade. Para as crianças de 6 anos, o TR com dica correta foi ligeiramente mais rápido do que na condição sem dica. Todavia, na condição com dica incorreta, o TR para as crianças de 6 anos era mais lento comparado com os demais grupos. Com respeito à execução da ação motora, os resultados indicaram mudanças desenvolvimentais em todas as variáveis dependentes, TM, TD, IR, UnM. De modo geral, os resultados do presente estudo mostraram que aos 6 anos de idade crianças são capazes de utilizar informação antecipada para preparar uma simples ação de alcance...

Avaliação do uso de fantomas antropomórficos na análise experimental dos fatores que afetam o contraste de imagens radiográficas

This experimental study aimed the evaluation of the use of anthropomorphic phantoms in the analysis of the influence of the acquisition parameters in the contrast of radiographic images. The analyzed factors were the variation of the peak kilovoltage (kVp) and the product of the filament circuit by the time of exposition (mAs). The influence of these factors was verified for different anthropomorphic phantoms: foot, knee and chest. The image contrast behavior with the simulators was compared to values obtained with the use of an aluminum ladder being the behavior of this reference for analysis and discussion. To assure the reproducibility of images, quality control tests were made and evaluation of procedure conditions before the experiments. The results obtained are shown in a scale of images where it was possible to evaluate the impact in the darkness of images. Regions with different compositions were analyzed which were different in image, this way the values of optical density and contrast are represented as charts and graphics. We conclude that the use of anthropomorphic phantoms in the evaluation of the influence of tension of the tube and time of exposition in the contrast of the radiographic images is not indicated for a quantitative analysis through optical density, once they present incompatible results with the data as reference as the aluminum ladder even so these simulators present a great property in qualitative analysis regarding the differentiation of structures and subjective evaluations

Análise de atividade epileptiforme com uso simultâneo de eletrencefalografia e ressonância magnética funcional

The use of multimodal neuroimaging techniques has been helpful in the investigation of epileptogenic zone in patients with refractory epilepsies. This work aims to describe an ictal event during EEG-fMRI performed simultaneously in a 39-year-old man with refractory epilepsy. The EEG data were recorded at a sampling rate of 5 kHz, using a BrainAmp (BrainProducts, München, Germany) amplifier, with 64 MR (magnetic resonance) compatible Ag/AgCl electrodes. MR images were acquired using a 3T scanner in 3 sequences of 6 minutes of echo-planar images (EPIs), with TR = 2s, being the last sequence stopped after the ictal event. The EEG was corrected for gradient and pulse artifacts using the Brain Vision Analyzer2 software (BrainProducts), and the functional images were realigned, slice-timing corrected, normalized and smoothed. The start of the ictal changes was used for the evaluation of the BOLD response in MR images, using a t-test with a minimum cluster of 5 voxels, p <0.005 (T>2.5). The patient had a partial complex seizure, as noted by neurologist. The fMRI data showed positive BOLD responses (activation) in dysplastic areas, but showed the most significant activation outside the lesion, in areas compatible with secondary spread of the epileptic focus, probably caused by motor reaction also observed during the seizure. As a conclusion, we note that the technique of EEG-fMRI can detect the epileptogenic zone in patients with refractory epilepsy, but areas of dissemination of primary epileptogenic focus may show significant activation, introducing additional difficulties to the interpretation of the results
