Comportamento de pesquisa da informação no Facebook por estudantes de Biblioteconomia da UnB

Monografia (graduação)—Universidade de Brasília, Faculdade de Ciência da Informação, 2014.Aborda o comportamento de pesquisa da informação na ferramenta da Web 2.0, Facebook, pelos estudantes a partir do 7º Semestre do curso e recém-formados em Biblioteconomia na Universidade de Brasília. A pesquisa ocorre mediante análise documental e análise quantitativa, por meio de questionário aplicado via Web. Os resultados obtidos identificam que o público-alvo utiliza a Internet diariamente e acessa o Facebook principalmente para fins de entretenimento. Porém, considera que ele seja uma ferramenta importante de divulgação referente ao mercado de trabalho. Quanto à literatura da área de biblioteconomia postada no Facebook, ainda existem barreiras de aceitação ao relacionar sites de rede social com conteúdo científico. Além disso, os estudantes em final de curso e bacharéis em biblioteconomia costumam pesquisar a veracidade de notícias lidas no Facebook em outras fontes informacionais, e que o excesso de propagandas de serviços, produtos e eventos é o principal obstáculo que dificulta o acesso à informação. _________________________________________________________________________________ ABSTRACTIt addresses the information behaviour research in the Web 2.0 tool, Facebook, by students from the 7th semester and recently graduated in Librarianship at the University of Brasilia. This is a survey conducted through documentary analysis and quantitative analysis, using a questionnaire applied via Web. The results show that the target audience uses the Internet daily and accesses the Facebook mainly for entertainment purposes. However, they consider it as an important tool for disclosure connected to the labor market. Concerning the literature of the area as a benefit provided by Facebook to librarians, it was found that there are barriers to the acceptance related to social networking sites with scientific content. It was found that students in final year and graduated in librarianship often search for the veracity of news read on Facebook in other informational sources; also the excess of service advertisements, products and events is the main obstacle that makes the access to information more difficult

ANÁLISE DE FREQUÊNCIA DE PRECIPITAÇÃO E CARACTERIZAÇÃO DE ANOS SECOS E CHUVOSOS PARA A BACIA DO RIO ITAJAÍ

Eventos extremos de precipitação influenciam a sociedade de forma direta e indireta. Dependendo de sua magnitude e extensão, os danos gerados por estes eventos podem, na maioria das vezes, ser enquadrados na categoria de desastres naturais. O objetivo deste trabalho é estabelecer e discutir valores normais e extremos para a chuva na bacia do Rio Itajaí, através da utilização da técnica estatística dos quantis, utilizando dados de precipitação das estações convencionais da Agência Nacional de Águas (ANA), no período de 1930-2013. O cálculo de frequência de classes de chuva foi realizado empregando-se as classes recomendadas pelo Instituto Nacional de Meteorologia (INMET). A análise de frequência mostrou que a classe de precipitação 0,1-2,5mm é a mais comum, com ocorrência superior a 14,5%. As classes entre 50-100mm e >100mm não chegam a ultrapassar 5% de frequência. Quanto aos anos com os maiores acumulados anuais, destacam-se os anos de 1983 e 1998 e 200

EXTREMOS DE PRECIPITAÇÃO E OCORRÊNCIA DE DESLIZAMENTOS DE TERRA NA BACIA DO RIO ITAJAÍ

Estudos voltados para avaliação de áreas suscetíveis a movimentos de massa têm sido realizados em diversas regiões do Globo, especialmente em áreas urbanas e regiões de alta pluviosidade. O objetivo deste trabalho é analisar informações sobre movimentos de massa e extremos de precipitação na bacia do Rio Itajaí, assim como conhecer a magnitude dos eventos adversos a partir dos relatórios da Defesa Civil, através associação entre registros de deslizamento de terra disponíveis no banco de dados do Sistema Nacional de Defesa Civil e chuvas extremas. Os resultados indicaram que 42,7% dos casos de deslizamento de terra ocorreram em dias de chuvas extremas, sendo que, em 94,% dos casos, os extremos foram precedidos por dias consecutivos de chuva. O maior número de ocorrências foi registrado nos anos 2001, 2008, 2011 e 2013, principalmente na estação da primavera

Building a National IoT Plan: Policy Recommendations and the Case of Brazil

The Internet of Things (“IoT”) is an expression that refers to a whole set of new services and devices that includes at least three fundamental aspects: connectivity, use of sensors or actuators, and computational capacity for data processing and storage. The Internet of Things goes beyond connecting objects to each other; it also gives them the power to process data (thereby making them "smart"). For developing countries such as Brazil, the opportunities offered by the Internet of Things can compensate for shortcomings in infrastructure and services, and can improve innovation, quality of life, productivity, and even the economic complexity of our basket of export products. However, the way in which each country will seize this opportunity will depend on its specific aspirations and strategies. The broader economic, social, political, and legal context of the country should be considered, as well as the local development of information and communication technologies. For this reason, the National Bank for Economic and Social Development (BNDES), in partnership with the Ministry of Science, Technology, Innovation and Communications (MCTIC), has commissioned this study, "Internet of Things: An Action Plan for Brazil." This study, mapped by a consortium comprised by McKinsey & Company, the CPqD Foundation, and Pereira Neto | Macedo Law Firm, outlines the local technological and economic challenges related to the topic, as well as well as how to address legal issues inherent to the development of IoT in Brazil

Effects of plant protease inhibitors (Pep-3-EcTI, Pep-BbKI, and Pep-BrTI) versus corticosteroids on inflammation, remodeling, and oxidative stress in an asthma–COPD (ACO) model

The peptide derived from E. contortisiliquum trypsin inhibitor (Pep-3-EcTI), peptide derived from kallikrein inhibitor isolated from B. bauhinioides (Pep-BbKI), and B. rufa peptide modified from B. bauhinioides (Pep-BrTI) peptides exhibit anti-inflammatory and antioxidant activities, suggesting their potential for treating asthma–chronic obstructive pulmonary disease (COPD) overlap (ACO). We compared the effects of these peptides with dexamethasone (DX) treatment in an ACO model. In this study, 11 groups of male BALB/c mice were pre-treated under different conditions, including sensitization with intraperitoneal injection and inhalation of ovalbumin (OVA), intratracheal instillation of porcine pancreatic elastase (ELA), sensitization with intraperitoneal injection, and various combinations of peptide treatments with Pep-3-EcTI, Pep-BbKI, Pep-BrTI, dexamethasone, and non-treated controls (SAL-saline). Respiratory system resistance, airway resistance, lung tissue resistance, exhaled nitric oxide, linear mean intercept, immune cell counts in the bronchoalveolar lavage fluid, cytokine expression, extracellular matrix remodeling, and oxidative stress in the airways and alveolar septa were evaluated on day 28. Results showed increased respiratory parameters, inflammatory markers, and tissue remodeling in the ACO group compared to controls. Treatment with the peptides or DX attenuated or reversed these responses, with the peptides showing effectiveness in controlling hyperresponsiveness, inflammation, remodeling, and oxidative stress markers. These peptides demonstrated an efficacy comparable to that of corticosteroids in the ACO model. However, this study highlights the need for further research to assess their safety, mechanisms of action, and potential translation to clinical studies before considering these peptides for human use

Skin color and severe maternal outcomes: evidence from the brazilian network for surveillance of severe maternal morbidity

Taking into account the probable role that race/skin color may have for determining outcomes in maternal health, the objective of this study was to assess whether maternal race/skin color is a predictor of severe maternal morbidity. This is a secondary analysis of the Brazilian Network for Surveillance of Severe Maternal Morbidity, a national multicenter cross-sectional study of 27 Brazilian referral maternity hospitals. A prospective surveillance was performed to identify cases of maternal death (MD), maternal near miss (MNM) events, and potentially life-threatening conditions (PLTC), according to standard WHO definition and criteria. Among 9,555 women with severe maternal morbidity, data on race/skin color was available for 7,139 women, who were further divided into two groups: 4,108 nonwhite women (2,253 black and 1,855 from other races/skin color) and 3,031 white women. Indicators of severe maternal morbidity according to WHO definition are shown by skin color group. Adjusted Prevalence Ratios (PRadj - 95%CI) for Severe Maternal Outcome (SMO=MNM+MD) were estimated according to sociodemographic/obstetric characteristics, pregnancy outcomes, and perinatal results considering race. Results. Among 7,139 women with severe maternal morbidity evaluated, 90.5% were classified as PLTC, 8.5% as MNM, and 1.6% as MD. There was a significantly higher prevalence of MNM and MD among white women. MNMR (maternal near miss ratio) was 9.37 per thousand live births (LB). SMOR (severe maternal outcome ratio) was 11.08 per 1000 LB, and MMR (maternal mortality ratio) was 170.4 per 100,000 LB. Maternal mortality to maternal near miss ratio was 1 to 5.2, irrespective of maternal skin color. Hypertension, the main cause of maternal complications, affected mostly nonwhite women. Hemorrhage, the second more common cause of maternal complication, predominated among white women. Nonwhite skin color was associated with a reduced risk of SMO in multivariate analysis. Nonwhite skin color was associated with a lower risk for severe maternal outcomes. This result could be due to confounding factors linked to a high rate of Brazilian miscegenation.2019CNPQ - Conselho Nacional de Desenvolvimento Científico e Tecnológico402702/2008-
