O comportamento informacional de pós-graduandos da área de Educação

The study of information behavior of graduate students is important because it reveals aspects of the search and information use that will impact the performance of future researchers and other professionals. Earlier studies on the UNESP, campus of Marilia (São Paulo State, Brazil), indicated that the graduate students in the areas of Applied Social Sciences and Humanities little use information sources traditionally used for bibliographic and restricted to the sources indicated by their teachers, contrary to expectations for a student with this level of training. Continuing the theme, we investigate the information behavior of students in postgraduate programs in the field of Education with five and six notes in the latest assessment of the Coordination of Improvement of Higher Education Personnel (CAPES). This research aimed to characterize the information behavior of Brazilian post-graduate in Education; identify factors that may influence the information behavior of the participants; investigate whether there are significant differences in behavior between masters and doctoral students; check the influence of gender in information behavior of post-graduate students. Data collection was performed in two stages: the establishment of a focus group with group of 11 participants for raising subsidies for the next step, which consisted in the application of electronic questionnaire to 16 graduate regular student of programs of excellence in the Brazil. Participated in the survey 493 post-graduates, 54% doctoral students and 46% of masters students and 75% women and 25% of men. The results showed that most subjects did not participate in formal instruction to search in databases. They are open to new ideas and do not restrict your search only to information that confirms their view on the research topic. Respondents are concerned not to overlook details and have the habit of regularly seeking information on their research and were willing to...

Os 600 transplantes renais do Hospital das Clínicas da Faculdade de Medicina de Botucatu (HC da FMB) - UNESP: Mudanças ao longo do tempo

Introdução:Os resultados alcançados pelos transplantes renais nas últimas décadas têm melhorado progressivamente. Objetivo:A fim de determinar a extensão desse progresso, conduzimos uma análise dos resultados obtidos em nosso programa de transplantes através de três períodos diferentes. Métodos:Avaliamos os 600 transplantes renais realizados no HC FMB-UNESP até dezembro de 2011, subdividindo-os em três eras, de acordo com a imunossupressão vigente. Era 1: de 1987 a 2000 (n = 180); associação de ciclosporina e azatioprina. Era 2: de 2001 a 2006 (n = 120); associação de ciclosporina e micofenolato e Era 3: de 2007 a 2011 (n = 300); associação de tacrolimus e micofenolato. Resultados:Os resultados mostram aumento da idade média do receptor, da prevalência de diabetes e do número de transplantes com doador falecido (60%) na terceira era. O uso de terapia de indução foi de 75% era atual contra 46,6% (Era 2) e 3,9% (Era 1), p < 0,0001. Os dados de sobrevida geral por tipo de doador mostram dados semelhantes à literatura. Houve progressivo aumento da sobrevida do enxerto com doadores falecidos em 5 anos, saindo de 13,7% (Era 1) para 81,9% (Era 3). Conclusão:Houve significativas diferenças ao longo do tempo, culminando com aumento do volume de transplantes na atual era (média de 14 transplantes/ano na Era 1 para 75 transplantes/ano na Era 3). Inverteu-se o perfil de transplantes na era atual com predomínio de doador falecido. A melhor sobrevida com doador falecido da atual era foi atribuída a maior experiência do centro e aos esquemas de imunossupressão baseados na combinação de tacrolimus com micofenolato associados a esquema de indução.

Estudo do comportamento cortisol, gh e insulina apos uma sessao de exercicio resistido agudo

INTRODUÇÃO:Muitos trabalhos têm estudado o comportamento hormonal nos exercício resistido, entretanto poucos relacionam os hormônios cortisol, GH e insulina.OBJETIVO:Estudar os ajustes das concentrações plasmáticas dos hormônios cortisol, GH e insulina em exercícios resistidos de mesma intensidade com relação à massas musculares distintas.MÉTODOS:Dez voluntários, com 20,3 ± 4,2 anos, 74,1 ± 10,2 kg de peso, 177,2 ± 4,6 cm de estatura e 23,8 ± 3,2 kg/m2 de IMC, realizaram uma sessão de leg press (LP) e supino reto (SR) com quatro séries com 10 repetições a 70% 1 RM com três minutos de intervalo. Foram coletadas amostras de sangue para dosagem das concentrações plasmáticas de cortisol, GH e insulina em repouso (Pré) e em 0' (Rec. 0'), 30' (Rec. 30') e 90' (Rec. 90') de recuperação.RESULTADOS:As concentrações plasmáticas de cortisol foram significativamente reduzidas ao final da recuperação em LP (2,20±0,37 ng/dl para 1,33±0,38ng/dl) em relação à pré-dosagem. As concentrações de GH e insulina elevaram-se significativamente durante a recuperação. GH em LP foi significativamente maior em Rec. 0' (2,75±3,29 ng/ml para 9,60±5,32 ng/dl) do que em pré. A insulina elevou-se significativamente em Rec. 30' em LP (14,70±7,92 ulU/ml para 21,66 ± 8,61 ulU/ml) e em SR (6,17 ± 2,99 ulU/ml para 19,70 ± 13,8 ulU/ml) em relação à pré. As concentrações plasmáticas de insulina pré em LP foram significativamente superiores a SR (14,70 ulU/ml e 6,17 ± 2,99 ulU/ml).CONCLUSÃO:O exercício resistido promoveu diferentes ajustes nas concentrações hormonais de cortisol, GH e insulina durante o período de recuperação.

Cyanobacteria detection in Guarapiranga Reservoir (São Paulo State, Brazil) using Landsat TM and ETM+ images

Algae bloom is one of the major consequences of the eutrophication of aquatic systems, including algae capable of producing toxic substances. Among these are several species of cyanobacteria, also known as blue-green algae, that have the capacity to adapt themselves to changes in the water column. Thus, the horizontal distribution of cyanobacteria harmful algae blooms (CHABs) is essential, not only to the environment, but also for public health. The use of remote sensing techniques for mapping CHABs has been explored by means of bio-optical modeling of phycocyanin (PC), a unique inland waters cyanobacteria pigment. However, due to the small number of sensors with a spectral band of the PC absorption feature, it is difficult to develop semi-analytical models. This study evaluated the use of an empirical model to identify CHABs using TM and ETM+ sensors aboard Landsat 5 and 7 satellites. Five images were acquired for applying the model. Besides the images, data was also collected in the Guarapiranga Reservoir, in São Paulo Metropolitan Region, regarding the cyanobacteria cell count (cells/mL), which was used as an indicator of CHABs biomass. When model values were analyzed excluding calibration factors for temperate lakes, they showed a medium correlation (R²=0.81, p=0.036), while when the factors were included the model showed a high correlation (R²=0.96, p=0.003) to the cyanobacteria cell count. The empirical model analyzed proved useful as an important tool for policy makers, since it provided information regarding the horizontal distribution of CHABs which could not be acquired from traditional monitoring techniques.

Comparison of Botu-bov and Tris as Freezing Extenders of Buffalo Sperm Recovered from Epididymal Cauda

Valuable genetic material can be preserved by the cryopreservation of epididymal sperm. This study evaluated the viability of pre-freezing and post-thawed sperm samples recovered from the epididymal cauda of buffaloes. Epididymides from eight Murrah buffaloes with 18 months of age were used. Semen samples were diluted in two different freezing extenders: Botu-bov (BB) and Tris (TRIS). Immediately after slaughter, both testicles from each animal were collected and transported at 4 degrees C for six hours interval. In laboratory, the removed epididymides were flushed to obtain sperm and the fractions were diluted in both freezing extenders (BB and TRIS). Semen doses were analyzed before and after frozen at -196 degrees C. BB and TRIS pre-freezing results were 38.54 +/- 22.33%(b) and 14.17 +/- 12.78%(a) for total motility (TM), 25.00 +/- 16.12(a) and 9.44 +/- 9.11(a) for progressive motility (PM), 7.21 +/- 0.98(a) and 5.09 +/- 2.65(a) for percentage of rapid cells (RAP), 91.08 +/- 12.53(b) and 63.33 +/- 31.47(a) for velocity of trajectory (VAP), 73.54 +/- 20.17(b) and 49.50 +/- 9.11(a) for linear progressive velocity (VSL), 172.21 +/- 24.55(a) and 116.94 +/- 59.48(a) for curvilinear velocity (VCL), respectively (P < 0.05). BB and TRIS post-thawing results were 42.25 +/- 21.50(b) and 17.62 +/- 19.46(a) for TM, 27.25 +/- 24.86(a) and 18.00 +/- 13.68(a) for PM, 7.35 +/- 0.98(a) and 6.26 +/- 1.13(a) for RAP, 91.42 +/- 16.86(a) and 75.96 +/- 13.17(a) for VAP, 67.96 +/- 12.13(a) and 60.04 +/- 10.42(a) for VSL, 177.54 +/- 23.53(b) and 141.29 +/- 24.97a for VCL, respectively (P < 0.05). The sperm recovered from the epididymal cauda, after 6 h storage of epididymides at 5 degrees C ensures sperm preservation demonstrating that the diluent Botu-bov had higher total motility both pre-and post-freezing when compared with TRIS. Additionally, the sperm frozen with the diluent Botu-bov showed higher values of VSL at post-thawing. These findings may reflect in improvement of conception rates.

Tecnologias de Informação e Comunicação no cotidiano dos adolescentes: enfoque no comportamento e na competências informacionais da geração Google

Introduction: Individuals born from the 1990’s to accompany technological change course and learn how to use the technological resources that have access before they even learn to read or write. In this sense, the literature considers the digital natives or even 'Google generation'. However, it has been questioned their skills to identify information needs and seeking and use of information in the most varied environments digital information available on the Web. Objectives: To characterize the behavior of information seeking in everyday life of a group of teenage students from a private school in Marilia, Sao Paulo. Methodology: A qualitative study with 30 adolescent students of a private school in Marilia, Sao Paulo. Data collection was accomplished at first by means of a questionnaire, based on the research of Hughes-Hussell and August (2007), containing questions about age, gender, hobbies and everyday tasks, and issues the use of computers and the internet, which allowed determination of the social, economic and cultural rights of respondents. Results: have focused on the use of Information and Communication Technologies (ICT) to search access and use information. It was suggested that the "Brotherhood of Informatics', an incentive for students to (re) learn the tools of digital communication and make appropriate use of the resources, products and services on the web to search and effective use of information compatible with their needs and that is tied to the ethical and responsible use of technology environments. Conclusions: The results arising from this study will continue through the continuation of the Confraternity of Computing, which became a "thermometer" on the use of digital information environments and the attitude of the students in front of Information and Communication Technologies in the College “Cristo Rei”.

Realismo, Nominalismo e Cartesianismo: Sentido e natureza das idéias como representações do mundo

The approach about the ideas, understood as metal representations, has practically bookmarked the whole Philosophy History, since the ancient Greece to the contemporary period. A lot of interpretations have been given to the meaning and to the nature of the ideas by many schools, among them lots of Realism slopes. This paper aims to present, from a historical and epistemological fragment, some theoretical perpectives, with emphasis in the realistic, nominalist and Cartesian proposals in relation to the formation and nature of the ideas.
