Letramento no trânsito: eventos e práticas na formação de condutores de veículos

In the contemporary society, the language is presented in all social spaces and assumes many different purposes in order to meet the needs that emerge from each of these sphere. In traffic, this reality is not different. To guide vehicles, it is necessary to know, by means of reading artifacts, what the legislation establishes in what concerns the way to act in this domain. Thus, this works aims at describing the practices of literacy held in events of driver trainings and know the expectations generated by drivers/learners from this training. In theoretical terms, it anchors in Literacy Studies, comprehended here as social practices (BARTON; HAMILTON, 1998; KLEIMAN, 1995, 2008; MORTATTI, 2004; STREET, 1984; OLIVEIRA, 2008, 2010; ROJO, 2009; PAZ, 2008). Genre Theory (BRONCKART, 2004, 1999; OLIVEIRA, 2010) and in your multimodal instance (KRESS; VAN LEEUWEN, 1996; DIONÍSIO, 2006). In terms of methodology, it follows the bias of qualitative research, because of its ethnographic nature (BOGDAN; BIKLEN, 1994; MINAYO, 2010; CANÇADO, 1994; CHIZZOTTI, 2005). The research corpus was generated by reading the Brazilian Traffic Code, by observing the literacy events held in Drivers Training Centers of Natal, analysis of course books used in these events, plus questionnaires with open and closed questions and semistructured interviews. The collaborators are constituted of drivers in training, and instructors who work in this field. The analyses show significant contributions regarding the placement more committed of future drivers with the welfare and safety of those who use the public roads, from the practice or reading done during the traffic training. The contribution of this work lies in the possibility to expand the discussion about the language practice uses regarding the training for the traffic, more specifically, the training of drivers of vehicles

A produção do gênero monografia em discursos de professores e alunos do curso de letras

A current worry in the teaching process at the university these days is text production process and genres produced there, especially those kind of writing that is concerned to course conclusion such as monograph, dissertation and thesis. From this perspective and considering our aims at understanding discursive process involved in the production of monograph genre at the university we want to analyze teachers and students discourses about the productive process of monograph in Letras Course, considering the guide, writing and specific aspects of that genre. To get the aims, we took as background theory the studies by Bakhtin linked to Utterance Linguistics with foundation concepts in Discourse Text Analysis by Adam (2010), and finally the studies developed about text production at college. This way, this work is based on a qualitative research and in data ethnographic procedures, they are: the observation in locus, as well as the application of questionnaires with opened questions to ten students and six teachers from Letras Course. The discourse analysis from the subjects reveal us that: i) the monograph production and the guidance are form of act by language, that need take into account in its development: students free chose as a principle in writing monograph, as well as a wide involvement between the teacher and the student in a sense to turn the writing better, among other aspects; (ii) there is a need to articulate monograph project and the text produced, considering that the guide process comes from a project written before; (iii) there are a number of role to discourses by teachers and students to the function of student and guide teacher, in a way that both can see the same assumptions in teachers and students discourses; (iv) teacher s and students discourses show that they assume the utterance responsibilities by the content of utterances proposed, they also show the voice from methodology guidebooks to monograph texts. So, we conclude that this research has some contributions to teach writing production at the university, especially to monograph in the ending of the courses. It can also be helpful in developing research in this area, mainly at the question about guide final works at college

Analisando conhecimentos e práticas de agentes educacionais e professoras relacionados à alimentação infantil

Objetivou-se identificar os conhecimentos e as práticas relacionados à alimentação de crianças entre zero e três anos, a fim de complementar a formação das profissionais que trabalham com crianças, na área da educação nutricional. O procedimento metodológico seguiu as orientações do estudo de caso, com abordagem qualitativa. Os saberes e as práticas das participantes do estudo foram analisados por meio de questões abertas e fechadas e das observações dos tópicos relacionados à nutrição infantil, juntamente com os dados sobre a formação dessas profissionais. Pode-se concluir que tanto as agentes educacionais quanto as professoras de Ensino Infantil são detentoras de um conhecimento sobre Nutrição Infantil, porém a preocupação maior destas foi atender as necessidades nutricionais das crianças por meio de uma boa alimentação, deixando, em segundo plano, as atividades pedagógicas, as quais poderiam ser realizadas em um programa de educação nutricional, construído coletivamente e inserido no projeto político-pedagógico da escola.

Atuação profissional e vivência do cirurgião-dentista na estratégia do programa de saúde da família

The purpose of this research was to analyze the working profile of dentists from the Family Health Program (PSF Programa de Saúde da Família, Brasil) of some Municipal Districts of Rio Grande do Norte (Brazil) in order to understand the way they handle the experience acquired with the work developed in that Program. This discussion evolves a reflection about the perspectives of consolidation of the FHP as well as the possible advancements of the Brazilian Unified Health System (SUS - Sistema Único de Saúde). The target population was composed of dentists from the FHP of Rio Grande do Norte. Thus we performed twenty-one interviews orientated by a semi-structured guidebook with open questions and identification data. We opted for recording the speech of all the professionals in order to ensure the accuracy of the information gathered. The main results found were: predominance in the female gender; the majority of dentists has no post graduation courses; in those few cases of dentists with some post-graduation a lack of correlation with Public or Collective Health was observed; the dentists interviewed present a profile directed to clinical activities; the dentists used to develop basic restorative and periodontic treatment, simple surgeries and educative and preventive activities, even though the last two ones are carried out in an extremely traditional way (lectures and topical application of fluoride). In addition, as biggest difficulties to manage the work dentists pointed out the lack of permanent and consumer material, inadequate infrastructure, no transport to take them to distant places, no integration with the Health Family Team, technical difficulty such to perform educative and preventive activities as to provide adequate service to a repressed lawsuit. The results indicate the existence of a necessity to lead them to reflect and redirect their practices. In order to reach this aim it must be considered as initial measure the investment and encouragement toward to permanent education as well as a close follow-up and evaluation of the actions developed by them

Percepção ambiental por uma comunidade rural do entorno de uma reserva particular do patrimônio natural (RPPN), semiárido brasileiro

Com o aumento dos problemas ambientais surgiram várias formas de proteção da natureza, como a criação de Unidades de Conservação (UC s) para preservar a biodiversidade que, por si, não tem obtido os resultados esperados. Para isso, a Percepção Ambiental (PA) vem sendo utilizada em estudos que tratam da relação homem-ambiente. Uma dessas UC s é a Reserva Particular do Patrimônio Natural (RPPN) Stoessel de Britto, no Estado do Rio Grande do Norte. Este trabalho teve como objetivos identificar o perfil socioeconômico e analisar a PA da comunidade do entorno dessa RPPN para conhecer os significados e atitudes que regem as relações estabelecidas pela comunidade com os elementos naturais e a UC. Foi empregado o instrumento da PA, na forma de formulários com questões abertas e fechadas aplicados a 90 entrevistados, e os dados foram analisados através do método Análise de Conteúdo. Os resultados mostram que a maioria dos moradores reconhece esta RPPN como uma área de proibições e legalizada pelo Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis-IBAMA. A falta de investimentos e de apoio é considerada grande empecilho na proteção e para o desenvolvimento local

Significado do Trabalho e Escolha Acadêmico-Profissional: um estudo com universitários primeiranistas

Relations between the meaning attributed to work by first year university students and their academic and professional choice were analyzed. The participants were 921 students, 17-52 years old (M = 22; SD = 4.9), enrolled in 16 courses common to two college level institutions of the city of Natal, RN, one public, the other private. A questionnaire was designed for collecting data about the academic-professional choice, with open-ended and multiple choice questions. Work meaning was obtained by means of two questions on centrality and two scales pertaining to the Inventory of Motivation and Work Meaning: value and descriptive attributes. A socio-demographic set of questions ended the questionnaire. Data was entered in a SPSS (Statistical Package for the Social Sciences) database, allowing for the pertinent statistical analyses, such as frequency, t test, chi square, factor analysis, cluster analysis and ANOVA. Results indicated that the decision about academic-professional career was made by the majority of the participants (in first option, N = 921) without the adequate consideration of the socio-professional reality (80.7%) and personal internal resources (98.5%). When considering the second option (N = 654), only the first criterion was taken into account, but only by 12.5% of the sample. The main difficulties faced by students during the choosing process were, then, made apparent in the data. 46.8% of the participants were unsatisfied with the course they had started and were anticipating unpromising perspectives in relation to it. The first year students took work as the second most important aspect of their lives and demonstrated an idealized vision about it. Five patterns of work meaning were identified. In relation to centrality and the value and descriptive attributes, the university students displayed differentiation in the attribution of work meaning according to course and area of knowledge

Violência doméstica contra adolescentes: o olhar dos educadores sociais

Domestic violence as a specific expression of violence against adolescents, is historically constructed from phenomenon of power relations that permeate the gender, ethnicity and social class, requiring differentiated attention. Sorting in A mass grave of what is understood by a child and teenager under the doctrines of the law of the minor and of irregular situation resulted, in General, in the preparation for the teenage audience, of policies and actions, fragile and inefficient with regard to domestic violence. Despite the status of children and adolescents clearly define what is meant by child and teenager, break with the menoristas doctrines and embrace the doctrine of integral protection, even if there is little guidance for the public actions and policies geared to the theme. Such deficiency contributes to characterize the current practice of social educators about domestic violence, marked by the absence of specific training; by inadequate working conditions; lack of preparation of the network of care. Thus, with the objective to start the discussion regarding the elements that make up the practice focused on this issue, the present study proposes to problematizing the design held by social educators working in public Social assistance of the city of Natal/RN, regarding the issue of domestic violence against adolescents, by paying attention to such things as their vocational integration, their training and their working conditions. Adopts norteadoras references as having its roots in the Pedagogia Problematizadora, Paulo Freire, and socio-historical perspective. The methodological procedure of nature quali-quantitative was lifting censitário and psychosocial characterization of educators together to State and local Departments of assistance; the application of questionnaire to educators, composed of open and closed issues; and observation and field journaling activities of their work. Of network professionals, 111 64 replied to the questionnaire, which represents more than 50% of the total. Psychosocial characterization exposes data as the predominance of low family income and female professionals; the note identified that do not have a professional technical parameter, and the activities carried out in accordance with the representations of each professional the respect of labour, problematic and adolescents involved, revealing an individual perspective of action. And a preliminary analysis of responses to the questionnaire pointed out that such professionals are subjected to precarious working conditions, as well as one realizes a relative ignorance about the network of care for adolescents at risk and ACE, all this resulting in restricted marginalizantes conceptions, and misleading information regarding domestic violence against teenagers.

Problemas de aprendizagem sobre ligações químicas para estudantes de graduação

This research aims at identifying the learning problems in newly undergraduate students at university, interpreting the nature and causes of these problems, offering subsidies to overcome these difficulties and enabling a meaningful learning through which students give meaning to their learning. As an object for this work was chosen the theme Chemical Bonds - where were studied the forces between atoms to form molecules, compound ions and ionic crystalline structures - and is characterized as one of the most important subjects of Chemistry. In research, it was used a questionnaire with five open questions, answered by 147 students from the early periods of degrees in Chemistry at Universidade Federal do f Rio Grande do Norte. The answers revealed uncertainty on the part of students, both conceptual and representation, with superficial justifications, always using the octet rule to describe models of chemical bonds. Results suggest that these students had inadequate training in high school and that the examinations for entrance into the ranks were made according to flexible criteria less demanding in terms of knowledge. These observations have led to the conclusion that for future changes, it is necessary for high schools and in the early periods in universities favoring the adoption of pedagogical approaches in context and applying strategies to overcome the teaching of superficial memorization on Chemical Bonds, which probably have applied to the teaching of other subjects of chemistry

As diretrizes da política pública de saúde bucal e suas inflexões nos serviços da Clínica Odontológica da UFRN

The crisis that the Brazilian State have been crossing throughout the last decades has revealed intense oscillations in the the way of life of the population reality. In the health area, specifically of buccal health, new alternatives of attending to demands for odontological services have been increasing from the 1990 decade. The research had as objective to analyze the demand of the services of the clinic-school of odontology of the UFRN to identify the socio-economic profile of the users and the inflections of the standards of the National Politics of Buccal Health. The methodology is based on a dialectic perspective and a quali-quantitative boarding. It was used as instrument of data collection forms with open and closed questions, applied to two distinguished groups of citizens: 53 users of the services and 12 pupils of 9th and 10th term of the Odontology Course. The results reaffirm that, with the aggravation of the crisis of SUS (Sistema Único de Saúde- Single Health System) grow the difficulties of accessing the odontological services of the users majority. The subjects of the research make use of a regular socio-economic condition, with high school, own house, formal bond to labor and monthly medium income between 1 and 2 minimum wages. The conclusive analyses point to the selective and exculpatory character of the buccal health right, mainly, those users who find themselves in situation of extreme poverty and social vulnerability. Immediate and of lesser cost odontological assistance is what it s aimed, but the standards praised in the Public Politics of Buccal Health walk in another direction, requiring a bigger strongness of the formation bases and implementation of the programmatical actions since the academic field until the effectiveness of Politics of Buccal Health as a right while as a right to attention and care

Impactos sócio-econômicos e ambientais da introdução da Tilápia do Nilo, Oreochromis niloticus, em açudes públicos do semi-árido nordestino, Brasi

The stocking of exotic fish, especially the tilapia, has become a common practice in the public reservoirs of the Brazilian semi-arid region. The stocking of tilapias has had as its main aim the improvement of the fisheries in the reservoirs and consequently the improvement of the socio-economic conditions of the families that have fishing as the main source of income. However, the environmental risks associated with this practice are high and can lead to a loss in aquatic biodiversity and to changes in the quality of the water. The object of this work was to quantify the socio-economic and environmental effects of the introduction of the Nile tilapia in the public reservoirs of the semi-arid northeastern Brazil. The analysis of the fish yield of 100 public reservoirs from 1970 to 2000 demonstrated that the introduction of the Nile tilapia apparently contributed to an increase in the total fish yield from the late 1970 s until the mid-1980 s. Nevertheless, from that time onwards the fish yield in these reservoirs has fallen into decline to levels inferior to those observed prior to the introduction of the tilápia. The analysis of the fishing activity statistics of the Gargalheiras reservoir located in the city of Acari, Rio Grande do Norte, demonstrated that the introduction of the Nile tilapia in the reservoir has not significantly increased the fish yield, the gross overall income, the gross per capita income nor the number of fishermen actively fishing in the reservoir. On the other hand, the analysis of the fishing activity statistics of the Gargalheiras reservoir has revealed a significant reduction in the captures of other commercially important fish species after the introduction of the tilapia. This result suggests that the Nile tilapia could have negatively affected other species of fish in the reservoir, contributing to the decline in their stocks. In order to assess the perception of the fishermen concerning the effects of the Nile tilapia over other species of fish and the quality of the water, questionnaires containing open and multiple choice questions were applied with 30 fishermen from the colony of the Gargalheiras reservoir. The great majority of the local fishermen stated that the tilapia is currently the most important species of fish to those who depend on fishing as a source of income and that they have not caused damage to other species of fish nor to the quality of the water in the reservoir. However, the results of the present work indicate that the alleged socio-economic benefits, employed to justify the introduction of the Nile tilapia in the reservoirs, are overestimated while the environmental impacts of the introduction of this exotic species are underestimated

Bioecology of the uçá-crab, Ucides cordatus (Linnaeus, 1763), in Vitória Bay, Espírito Santo State, Brazil

A biologia de Ucides cordatus na Baía de Vitória (ES) foi avaliada como subsídio ao manejo populacional. As amostragens ocorreram mensalmente durante um ano (outubro/1998 a setembro/1999), com análise biométrica (LC = largura da carapaça; PE = peso total úmido) e de fatores abióticos em quatro transectos, com quatro faixas cada (margem à região supratidal). A densidade foi de 3,7±1,5 caranguejos.m-2, com incremento em direção à região supratidal, sendo a profundidade das galerias de 1,1±0,3 m. A salinidade da água intersticial diferiu entre as faixas, sendo mais elevada na região supratidal. Houve correlação significativa entre a abundância de exemplares e alguns fatores ambientais, o mesmo ocorrendo quanto as tocas abertas e fechadas. A razão sexual evidenciou um predomínio de fêmeas (1,0M:1,6F), particularmente entre 50 e 75 mm LC. A maior incidência de tocas fechadas ocorreu em agosto e setembro, enquanto as fêmeas ovígeras foram registradas de janeiro a abril. A relação PE/LC mostrou isometria para os machos (PE=0,425.10-3 LC3,0014; R²=0,99) e fêmeas (P=0,439.10-3 LC2,97; R²=0,99). Para o total da população a média de tamanho (LC) e peso (PE) foi de 54,6±11,8 mm e de 77,5±42,4 g, respectivamente. Os dados evidenciam que a população encontra-se sobrexplotada, requerendo manejo adequado para a viabilidade da atividade extrativa na área estudada.
