A competência leitora de alunos do ensino fundamental: uma proposta de intervenção

Reading is a activity of paramount importance in the life of every human being, since this practice is essential condition for the exercise of citizenship. Therefore, it is through reading that the student has access to the knowledge that part of the world around him. However, given the complexity involved in the process of learning to read, teach students to read is not an easy task because often they do not acquire the skills necessary to understand the texts. According to this view, the present study focuses on an educational intervention who aim at contribut to the development of reading competence of students in 6th grade "U" of the State School Senador José Bernardo, in São João do Sabugi - RN. The activities which were of that intervention process were conducted in Portuguese Language classroom and developed through didactic sequences drawn from reading strategies, based on the genres tale and news, since students had serious problems with regard to reading comprehension. Given the importance of meeting the aforementioned difficulty, we seek to develop a proposal for interactive reading activities through genres as a language of social practices, whose goal aimed read to understand and make sense of texts. This intervention proposal falls under the Applied Linguistics and to perform it, were taken as a basis some theories focused on the notion of language as sociointerativa practice, such as studies of Bakhtin (2006, 2011), Bronckart (2012) and targeted contributions to the teaching of reading activity, including, Solé (1998), Oliveira (2010), Kleiman (2013), Leffa (1996, 1999), Silveira (2005). Discussions about genres followed the studies of Bakhtin (2011), Marcuschi (2008), as well as other theoretical; the didactic sequences were constructed from Bronckart (2012), Dolz; Noverraz; Schneuwly (2013) and, with regard to the teaching of Portuguese Language, the guidelines were adopted contained in PCN / LP (1998), as well as in Antunes (2003, 2009) and other authors. The results showed that students in the 6th grade increased their understanding capacity of the read texts, by implementing the didactic and pedagogical actions, thereby acquiring the reading competence they needed to keep learning.

Usabilidade da Interface do Sistema Eletrônico de Editoração de Revistas: um estudo da revista BiblioCanto da UFRN

The electronic journals correspond publishing channels and dissemination of scientific information. Through them, users can spread their studies as well as developing new researches. One of the systems used for creation and e-journals management is the Electronic System for Journal Publishing (SEER), used in the construction of periodic portals, as well as the creation of magazines in isolation. In this purport, it is believed that the management systems and creation of e-journals should be developed (internally and externally) according to the needs of its users. In the case of internal development, some of these processes refer to the copyright registration and submission of articles, which, in turn, are relevant tasks in the editorial process. Thus, the proposed study, thematic Usability of scientific journals, aims to analyze the usability of the copyright registration process and submission of articles in the Electronic System for Journal Publishing through BiblioCanto magazine, part of the Electronic Journals Portal of the Federal University of Rio Grande do Norte (UFRN). For the realization of the research, two valuation techniques were used: the Usability Test with a total of twenty participants and the Cooperative Evaluation, with the same number of participants separated in four categories considered target audience of that magazine, namely: undergraduate students, graduate students, teachers and librarians. The results indicated that the two analyzed processes (copyright registration and submission of articles) need improvement. In the case of the registration process, the following needs are: signalizing of the conducting registration ambient; description and exclusion of requested information on the registration form. In the process of article submission, it is emphasized improvement of aspects: the early steps to submission, signaling of required fields, concise description of the steps, minimization and review of the steps. To this end, it is believed that in general idea the SEER partially meets the needs of its users regarding the usability of such software.

Recomendações para um sistema de sinalização tátil a partir de abordagens ergonômicas e da percepção do deficiente visual para o Campus Parnamirim do IFRN

This study reports recommendations for a tactile and graphic wayfinding system aiming to offer more orientability and mobility for visually impaired people (blindness and low vision) at Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte (IFRN), Parnamirim Campus. It was necessary to focus on visual impaired people and approach concepts like orientation and accessibility at the built environment. In order to provide the comprehension of a complex social phenomenon and preserve the meaningful characteristics of the events, this research has developed a single case study in which elements of Post Occupation Evaluation have been used. Its purpose was to allow not only a technical analysis, but also the user perception about the space in use. The chosen tool to collect the user’s opinions and considerations was the Walk Together Method. The collected and analyzed information has demonstrated that, although Parnamirim Campus has implemented some interventions in relation to the spatial accessibility, they are still not enough to create an environment which arranges safety and autonomy for the visual impaired people and the other ones who attend there. This study suggests that it happened because the engineering interventions at the Campus have been based on Brazilian technical standards NBR 9050:2004, which is proper for the physical impaired people, but it does not offer enough information to respond to all the specific needs demanded by all the classifications of visual impairment.

Autoeficácia de alunos de Administração: um estudo com concluintes do curso de graduação em Administração no Estado do Pará

The current study presents the characteristics of self-efficacy of students of Administration course, who work and do not work. The study was conducted through a field research, descriptive, addressed quantitatively using statistical procedures. Was studied a population composed of 394 students distributed in three Higher Education Institutions, in the metropolitan region of Belém, in the State of Pará. The sampling was not probabilistic by accessibility, with a sample of 254 subjects. The instrument for data collection was a questionnaire composed of a set of questions divided into three sections: the first related to sociodemographic data, the second section was built to identify the work situation of the respondent and the third section was built with issues related to General Perceived Self-Efficacy Scale proposed by Schwarzer and Jerusalem (1999). Sociodemographic data were processed using methods of descriptive statistics. This procedure allowed characterizing the subjects of the sample. To identify the work situation, the analysis of frequency and percentage was used, which allowed to classify in percentage, the respondents who worked and those that did not work, and the data related to the scale of self-efficacy were processed quantitatively by the method of multivariate statistics using the software of program Statistical Package for Social Sciences for Windows - SPSS, version 17 from the process of Exploratory Factor Analysis. This procedure allowed characterizing the students who worked and the students who did not worked. The results were discussed based on Social Cognitive Theory from the construct of self-efficacy of Albert Bandura (1977). The study results showed a young sample, composed the majority of single women with work experience, and indicated that the characteristics of self-efficacy of students who work and students who do not work are different. The self-efficacy beliefs of students who do not work are based on psychological expectations, whereas the students who work demonstrated that their efficacy beliefs are sustained by previous experiences. A student who does not work proved to be reliant in their abilities to achieve a successful performance in their activities, believing it to be easy to achieve your goals and to face difficult situations at work, simply by invest a necessary effort and trust in their abilities. One who has experience working proved to be reliant in their abilities to conduct courses of action, although know that it is not easy to achieve your goals, and in unexpected situations showed its ability to solve difficult problems

Simulação do transporte de poeiras radioactivas resultantes de um acidente no complexo de Angra dos Reis, Brasil

O objetivo da avaliação de impactos ambientais (AIA) é permitir uma análise integrada de possíveis impactos diretos ou indiretos ao meio ambiente decorrentes da implantação e operação de empreendimentos, de forma a propor de medidas ou programas que visem evitar, mitigar ou compensar tais impactos. Para tanto é necessário conhecer as diversas características das áreas direta e indiretamente afetadas pela instalação de um projeto, tais como as condições meteorológicas e climatológicas. Estas também são relevantes no estudo das emissões em cenários de operação regular ou acidental de empreendimentos, dada sua influência nas condições de transporte e de dispersão de poluentes na atmosfera. Neste trabalho é realizado um estudo das condições de dispersão de poluentes na atmosfera para a região da Central Nuclear Almirante Álvaro Alberto (CNAAA) em Angra dos Reis, no Estado do Rio de Janeiro, utilizando o modelo WRF, considerando um cenário acidental com liberações por 48 horas. Os dois episódios simulados representam os regimes de tempo predominantes na região obtidos a partir da análise pelo o método k-means sobre as EOFs para o campo de pressões ao nível médio do mar entre os anos de 1985 e 2014. A aplicação da metodologia dos regimes de tempo permite observar os fenômenos meteorológicos de grande escala persistentes e recorrentes sobre uma dada região, servindo como uma ferramenta para a elaboração de estudos e documentos técnicos que fundamentem a decisão dos órgãos reguladores.

Mover/se(r) a gênese do corpo entre/corpos e seus trajetos no processo coreográfico

This paper proposes a reflection on the body between/bodies, especially in contemporary dance, in their path that starts from the choreographic construction, permeating the body of the choreographer, the dancer s body and when fulfills themselves as artistic expression, the body of the spectator. Initially discusses the body in dance as a body/space for convergence, connectedness and continuity, from the thought of the Greek philosopher Epicurus of Samos, in dialogue with the thought of Maurice Merleau-Ponty, Gilles Deleuze and José Gil. Reflect about the creation of this body/space in the relationship choreographer/dancer using as connecting thread the experiences of the author in his artistic path. Finally describes the process of creating the scenic experiment (h)áporos, which constitutes the practice scene of this dissertation, having as main objective the creation of spaces of convergence and interaction between a proponent and an affluent body that, in this move, transforms itself and the space that now cohabits / is

Avaliação transcricional de Glutationas -transferases em PEIXE-ZEBRA (Danio rerio) e alterações causadas pela exposição á Microcistina-LR

As Microcistinas são heptapeptídios cíclicos produzidos como metabólitos secundários por diferentes espécies de cianobactérias, sendo relevantes pelo seu potencial hepatotóxico. Peixes apresentam estratégias bioquímicas para detoxificar contaminantes ambientais, incluindo a ativação de enzimas de fase II de biotransformação, que incluem as isoformas de glutationa S-transferase (GST). As GST catalizam a conjugação de glutationa reduzida (GSH) com uma variedade de xenobióticos, incluindo as microcistinas. O presente estudo avaliou os níveis transcricionais de quinze isoformas de GST a fim de identificar isoformas possivelmente envolvidas na detoxificação de contaminantes ambientais como a microcistina-LR (MC-LR) em Danio rerio. A técnica de PCR em tempo real (RT-qPCR) foi utilizada para avaliação dos níveis transcricionais, permitindo análise das GST em diferentes órgãos, abundância e a ativação/repressão das isoformas de GST pela exposição à MC-LR. Foram avaliados os possíveis efeitos causados em brânquia e fígado após exposição por 24 hs às concentrações de 5 µg.L-1 e 50 µg.L-1 de MC-LR. Baseado nos scores de estabilidade para oito genes normalizadores, foram selecionados glicose-6-fosfato desidrogenase (g6pdh), β-actina1 e beta-2-microglobulina (b2m); b2m, alfa-tubulina 1 (tuba) e β- actin1; e tuba, b2m e g6pdh, para normalização dos níveis trancricionais de GST para distribuição órgão-específica, abundância e efeito da MC-LR em brânquia e fígado, respectivamente. A avaliação transcricional da distribuição órgão-específica revelou níveis significativos de gstal e gstk1.1 no fígado; gstp1 e gstp2 em brânquia; mgst3a, gstr1, gstm2, gstm33, gstp1, gstp2 e gstk1.1 no intestino; gstm2, gstm3 e gstal no olho e gstt1a e gsta2.1 no cérebro. Considerando os níveis de transcritos para um dado órgão, gstk1.1, gstal, gstp1 e gstt2 foram mais abundantes nos órgãos de detoxificação, tais como o fígado, brânquias e intestino, enquanto gstt1a e gsta2.1 foram mais abundantes no rim. Em brânquia, gsta2.1 e gstt1b foram reprimidas por 5 µg.L-1 de MC-LR e mgst1.1 foi reprimida em 50 µg.L-1 de MC-LR. No fígado, as isoformas gst2.2 e gstp2 foram reprimidas em ambas as concentrações, gstal foi reprimida em 5 µg.L-1, e gstt1a e gstk1.1 foram reprimidas em 50 µg.L-1 de MC-LR. As isoformas gstal, gstr1, gstp1, mgst3a, gstm1, gstm2 e gstm3 não foram alteradas pela exposição a MC-LR. Os resultados obtidos fornecem informações para a escolha de isoformas específicas de GST possivelmente envolvidas na detoxificação/toxicidade de MC-LR, a serem melhores caracterizadas ao nível protéico e também contribui para a escolha de genes normalizadores a serem utilizados em outros estudos da mesma natureza
