L accès et la permanence des étudiants à l université sont très présents dans les débats actuels relatifs à l'enseignement supérieur. De nombreuses mesures sont prises dans les politiques d'accès dans le but de réduire les inégalités et d'encourager les étudiants ayant moins de chances d'entrer dans l'enseignement supérieur, comme les étudiants issus de l'enseignement public, qui ont encore un niveau inférieur à celui souhaité. Lorsque ces élèves réussissent à terminer leurs études secondaires, passer l'examen d'entrée et réussir leur entrée dans l'enseignement supérieur ils se considèrent comme « victorieux ». Cette étude (pour le Master de l UFRN), développée au sein du groupe de recherche de la formation et professionnalisation des enseignants (PPGed / UFRN), vise à étudier la trajectoire des élèves issus des écoles publiques qui accèdent à une université publique. Nous avons interviewé 12 étudiants, six de l'Université fédérale de Rio Grande do Norte (UFRN) et 6 de l'Université d'État de Bahia (UNEB) inscrits à différents cours du premier cycle (Licence). Nous cherchons savoir comment s est déroulé leurs parcours au sein de l'Université, notamment en ce qui concerne la préparation aux examens d'entrée à l université (Vestibular) , la motivation du choix de cours, la première année à l'université, les habitudes d'étude, la relation avec l'apprentissage et les perspectives quant à l'avenir des élèves interrogés. Nous nous sommes référés aux travaux menés par Zago (2006), Ramalho (2003), Charlot (1997), Galland et Gruel (2009), Coulon (2008), Tinto (1993), Doray et l'équipe canadienne du CIRST (2009). L'entrée à l'université comporte un triple processus, institutionnel (formelles et informelles), intellectuel (composantes cognitives et académiques) et social (vie sociale au sein de l'université). L'étudiant entre à l'université et y trouve une nouvelle culture, de nouvelles connaissances et devra apprendre à être universitaire. Apprendre à surmonter le moment de l étrangeté et bien passer par le processus de l'apprentissage des règles, des codes de son nouveau statut et s accommoder de sa position d étudiant à l'université, arrive enfin, le temps d'affiliation, c'est à dire, le moment de l'admission où l'étudiant se sent comme un «vétéran», et qu il peut dire que les dangers de l'abandon sont passés et qu il pourra continuer son parcours avec succès. Cette étude vise à apporter des connaissances nouvelles sur les étudiants issus des écoles publiques, comme contribution au domaine des politiques d'accès et de permanence à l université et de soutien pédagogique au sein de cette institution

This work discusses about the teacher salary in the primary school after the creation of the Fundo de Manutenção e Desenvolvimento do Ensino Fundamental e Valorização do Magistério (Fundef), in the public schools in Natal/RN, from 1996 to 2006. The salary is considered one of the politic dimensions of the valorization of teaching. We aim to analyze the implication of this fund to the teacher remuneration, with different levels of training, in the early career, comparing it to the annual minimum salary, during the same period. This study has a historic-critic approach, establishing the relationship between the elements into a particular context (valorization of teaching/ teacher salary) and the elements from general contexts (financing/ Fundef). Analyzing data of the teacher remuneration from municipal payroll and comparing them to the annual national minimum salary gave us the result that the teachers, in their early career, do not have remuneration with a satisfactory evolution. Teachers that finished high school received until three minimum salaries before the creation of Fundef (1996-1997), after that (in 1998) they received under two minimum salary. In addition to this, independently of the level of the teacher training, their remuneration is under three minimum salaries. Hence, we can infer that the politic of funds is distant from the ideal to valorize the professional of the municipal teaching

This work, named Teaching conditions: a study in municipal schools of Currais Novos RN (2009 to 2012) aims to analyze the status of teaching in schools in the municipality of Currais Novos RN in the period ranging from 2009 - 2012, considering infrastructure, initial and continued training and intensification and casualization of teaching factors in the context of the 1990s educational reformations. It, also, assumes that teaching is a constitutive part of capitalist society, and has been reconfigured with based on the new requirements demanded by the labor market. In order to conduct this study the considered data included the survey research Teaching Work in Basic Education in Brazil (2009 to 2010) , held in seven Brazilian states being: Pará, Rio Grande do Norte, Minas Gerais, Goiás, Paraná, Santa Catarina and Espírito Santo. Specifically selected for deepening of the study, there were schools in the municipality of Currais Novos in which semi-structured interviews were performed with teachers of the said municipality. This research is constituted of a qualitative and quantitative approach whose survey instruments adopted were, namely: documental research, literature review, interviews and surveys. The obtained data analysis allows us to infer that the teaching work performed by teachers in the states which participated in the survey has been influenced the changes in the labor market and educational reformations and has been taking on characteristics such as flexibility, tendency to precariousness and intensification; and this trend is also present in schools that were surveyed in the municipality of Currais Novos. As pertaining to the teachers conditions in classroom, these signs are more evident, considering that they had their duties and responsibilities extended beyond the classroom environment. The data also show that in general working conditions of teachers in national, state and local levels are unprofitable and heterogeneous, increasingly deepening the gap between school units and education networks. Therefore, the implantation of public policies that enhance the teaching work and improve their working conditions in all dimensions that directly interfere in their work are crucial

The present scenario is permeated by different comprehensions about the body and health. These are the result of a historical process experienced by men in different times and social contexts through which were being built. Faced this scenario, we emphasize the media as a powerful means of information and training ideas regarding the body and health of theses. The media also as a means of mediating information we present characteristics of the social scenario where is inserted. In our research we bring reflects about the comprehensions, knowledge and practices propagated by the way the body and health under "Medida Certa" of the program Fantastico the broadcaster Globo Telecommunications, in order to identify how Physical Education, has contributed the construction of knowledge disseminated. Therefore, we focus our analysis to the table "Medida Certa" exhibited by Fantastico in the months of April, May and June of 2011.The data for analysis were collected through the videos shown live in Fantastic and the information provided in the blog that table. Thus, we had 14 videos shown live, 16 videos posted on the blog, 97 posts in blog. As technique of analysis of the datas used of content analysis of the Bardin (2011). About body obtained as analytical categories: body as operating system; biological body; fragmented body exterior to the subject; body trailer quantified to patterns; subject body. How to health we analyze the categories of health existential: health existential based in biological indices of normality; health existential associated with weight loss and aesthetic patterns; health existential associated with physical activity and nutritional control; and finally we propose a comprehension of health existential. Therefore, from the analysis of the data evidenced a predominance of comprehensions, knowledge and practices about the body and health guided the biological constituents of the body, quantification and classification in medium and normal patterns on pervasive forms of care, in the linear association among physical activity and nutritional control with health, evidenced that Physical Education has contributed to these constructions, through some of his discourses with emphasis on biological aspects. Thus, in our study we advocate an understanding of not only the body as object, but also as a subject clipped by organic, cultural, historical and social elements, a living body, feeling, desire and above all expresses itself, and health viewed as something body, interlaced through the biological, cultural, historical and emotional aspects of this body that coexist in this society

The Urinary Tract Infection (UTI) in pregnancy is important as a consequence of the high incidence during the gestation. It is the third most common clinical complication in pregnancy affecting 10-12% of women whether prevalence is increasing in the first trimester of pregnancy, it may also contribute to maternal and infant mortality. Due the relevance for the results of obstetric and neonatal complications from UTI, these complications must be prevented, because it can lead to health hazards to pregnant women and newborns, producing a direct effect on morbidity and perinatal mortality. On this basis, it was defined as objectives of this research the identification of the profile of nurses from the Family Health Strategy (FHS) in the East and West Health Districts from the city of Natal / RN before the women with UTI and to verify the nurse performance during prenatal consultations. This is an exploratory study with a quantitative approach using a sample of 40 nurses active workers during this survey, it was approved by the Research Ethics Committee of the Universidade Federal do Rio Grande do Norte Protocol n0 232/10 P-CEP/UFRN and opinion n0 080/2011. The tool for data collection was a structured interview. The data collected were organized into an electronic database application Microsoft ® Excel 2007, exported and analyzed using the Statistical Package for Social Sciences (SPSS) version 17.0, and coded, tabulated and presented through tables and charts into their respective percentage distributions, using the descriptive and inferential statistical analysis, chi-square test and significance level of 5% (distribution in relative and absolute frequencies) in the independent variables. Therefore, it was observed from these results that the longer action of nurses in the FHS from the East and Weast health districts of the city of Natal/RN contributed to the development of a greater number of activities to control the incidence of UTI in women who are attended in the prenatal care service, proven by significance in statistics

This work provides a discussion involving the development of practices in Environmental Education (EE) in Natal-RN city, taking as reference the Programa Vamos Cuidar do Brasil com as Escolas (PVCBE). The EE is emphasized by importance it takes within the context of the reforms carried out in Brazil to formal education, especially from the decade of 1980. The investigations focus the effect of PVCBE in promoting the EE. We take as theoretical - methodological base the global/national guidelines on EE, carried out the non-participant observation, document analysis, and application of questionnaires and use of statistical techniques in the data tabulation. The results indicate that there has been reasonable progress to the achieving of an implementation policy of EE clearly qualitative, with a better coordination among municipal policymakers and the schools involved. It has been also noticed that there is a gap between what the law provides for a formal EE and what is carried out in practice. Despite the limitations noted, we must remember that actions have been achieved. Even considering that they are isolated action; they already show that there are possibilities of follow ways to processes based on the criteria of integration, reflexive action, quality and autonomy

Telecommunication is one of the most dynamic and strategic areas in the world. Many technological innovations has modified the way information is exchanged. Information and knowledge are now shared in networks. Broadband Internet is the new way of sharing contents and information. This dissertation deals with performance indicators related to maintenance services of telecommunications networks and uses models of multivariate regression to estimate churn, which is the loss of customers to other companies. In a competitive environment, telecommunications companies have devised strategies to minimize the loss of customers. Loosing customers presents a higher cost than obtaining new ones. Corporations have plenty of data stored in a diversity of databases. Usually the data are not explored properly. This work uses the Knowledge Discovery in Databases (KDD) to establish rules and new models to explain how churn, as a dependent variable, are related to a diversity of service indicators, such as time to deploy the service (in hours), time to repair (in hours), and so on. Extraction of meaningful knowledge is, in many cases, a challenge. Models were tested and statistically analyzed. The work also shows results that allows the analysis and identification of which quality services indicators influence the churn. Actions are also proposed to solve, at least in part, this problem

Nowadays, telecommunications is one of the most dynamic and strategic areas in the world. Organizations are always seeking to find new management practices within an ever increasing competitive environment where resources are getting scarce. In this scenario, data obtained from business and corporate processes have even greater importance, although this data is not yet adequately explored. Knowledge Discovery in Databases (KDD) appears then, as an option to allow the study of complex problems in different areas of management. This work proposes both a systematization of KDD activities using concepts from different methodologies, such as CRISP-DM, SEMMA and FAYYAD approaches and a study concerning the viability of multivariate regression analysis models to explain corporative telecommunications sales using performance indicators. Thus, statistical methods were outlined to analyze the effects of such indicators on the behavior of business productivity. According to business and standard statistical analysis, equations were defined and fit to their respective determination coefficients. Tests of hypotheses were also conducted on parameters with the purpose of validating the regression models. The results show that there is a relationship between these development indicators and the amount of sales

This Master s Thesis proposes the application of Data Envelopment Analysis DEA to evaluate economies of scale and economies of scope in the performance of service teams involved with installation of data communication circuits, based on the study of a major telecommunication company in Brazil. Data was collected from the company s Operational Performance Division. Initial analysis of a data set, including nineteen installation teams, was performed considering input oriented methods. Subsequently, the need for restrictions on weights is analyzed using the Assurance Region method, checking for the existence of zero-valued weights. The resulting returns to scale are then verified. Further analyses using the Assurance Region Constant (AR-I-C) and Variable (AR-I-V) models verify the existence of variable, rather than constant, returns to scale. Therefore, all of the final comparisons use scores obtained through the AR-I-V model. In sequence, we verify if the system has economies of scope by analyzing the behavior of the scores in terms of individual or multiple outputs. Finally, conventional results, used by the company in study to evaluate team performance, are compared to those generated using the DEA methodology. The results presented here show that DEA is a useful methodology for assessing team performance and that it may contribute to improvements on the quality of the goal setting procedure.

This Master s Thesis proposes the application of Data Envelopment Analysis DEA to evaluate the performance of sales teams, based on a study of their coverage areas. Data was collected from the company contracted to distribute the products in the state of Ceará. Analyses of thirteen sales coverage areas were performed considering first the output-oriented constant return to scale method (CCR-O), then this method with assurance region (AR-O-C) and finally the method of variable returns to scale with assurance region (AR-O-V). The method used in the first approach is shown to be inappropriate for this study, since it inconveniently generates zero-valued weights, allowing that an area under evaluation obtain the maximal score by not producing. Using weight restrictions, through the assurance region methods AR-O-C and AR-O-V, decreasing returns to scale are identified, meaning that the improvement in performance is not proportional to the size of the areas being analyzed. Observing data generated by the analysis, a study is carried out, aiming to design improvement goals for the inefficient areas. Complementing this study, GDP data for each area was compared with scores obtained using AR-O-V analysis. The results presented in this work show that DEA is a useful methodology for assessing sales team performance and that it may contribute to improvements on the quality of the management process.

Telecommunications play a key role in contemporary society. However, as new technologies are put into the market, it also grows the demanding for new products and services that depend on the offered infrastructure, making the problems of planning telecommunications networks, despite the advances in technology, increasingly larger and complex. However, many of these problems can be formulated as models of combinatorial optimization, and the use of heuristic algorithms can help solving these issues in the planning phase. In this project it was developed two pure metaheuristic implementations Genetic algorithm (GA) and Memetic Algorithm (MA) plus a third hybrid implementation Memetic Algorithm with Vocabulary Building (MA+VB) for a problem in telecommunications that is known in the literature as Problem SONET Ring Assignment Problem or SRAP. The SRAP arises during the planning stage of the physical network and it consists in the selection of connections between a number of locations (customers) in order to meet a series of restrictions on the lowest possible cost. This problem is NP-hard, so efficient exact algorithms (in polynomial complexity ) are not known and may, indeed, even exist

The telecommunications play a fundamental role in the contemporary society, having as one of its main roles to give people the possibility to connect them and integrate them into society in which they operate and, therewith, accelerate development through knowledge. But as new technologies are introduced on the market, increases the demand for new products and services that depend on the infrastructure offered, making the problems of planning of telecommunication networks become increasingly large and complex. Many of these problems, however, can be formulated as combinatorial optimization models, and the use of heuristic algorithms can help solve these issues in the planning phase. This paper proposes the development of a Parallel Evolutionary Algorithm to be applied to telecommunications problem known in the literature as SONET Ring Assignment Problem SRAP. This problem is the class NP-hard and arises during the physical planning of a telecommunication network and consists of determining the connections between locations (customers), satisfying a series of constrains of the lowest possible cost. Experimental results illustrate the effectiveness of the Evolutionary Algorithm parallel, over other methods, to obtain solutions that are either optimal or very close to it
