Inserção de fornecedores locais como fonte de desempenhos em custos de transação e legitimidade: estudo de caso na cadeia produtiva do petróleo e gás do Rio Grande do Norte

The inclusion of local suppliers in production chains has considerable impact on its performance, but most notably in its main actors. The results of this process may be of different kinds and can be analyzed from economic or institutional approaches. This study aimed to verify the existence of different performances of Petrobras due to the inclusion of local suppliers in the oil and gas production chain in the state of Rio Grande do Norte, from the viewpoints of transaction costs and the Institutional Theory. In order to this, were made the characterization of the PROMINP, the description of its actions and results, the mapping of its institutional context of reference, and identification of results obtained by Petrobras in terms of transaction costs and legitimacy. The theoretical framework is based on authors dealing with industrial concentration, as like Marshall, Krugman, Porter and Schmitz, from the sociological perspective of neoinstitucional theory, as like DiMaggio and Powell and Scott and Meyer, and transaction costs, as like Williamson. This is a qualitative research, with data collection done by consulting secondary fonts and semi-structured interviews with nineteen actors of three groups, namely: actors involved in actions of the program, representatives of enterprises and representative of Petrobras. To analyze the content was used the Suchman s model (1995) for categories associated with strategies of legitimation and fourteen variables associated with the three variables assets specificity, bounded rationality and opportunism (Williamson, 1995, 1989) in the case of transaction costs. The results indicate that PROMINP has achieved its objectives by encouraging the increased participation of local companies in the oil and gas production chain, reflecting in the economic development of the state. The Redepetro/RN, fostered and built upon the interaction of the participants, is presented as a solution of continuity to the participation of enterprises in the chain, after the closure of the actions of the program. PROMINP demands responses to coercive, legislative and regulatory pressures of the organizational field, whose institutional context of reference is wide. From the point of view of legitimacy, through strategies to gain cognitive legitimacy and maintaining pragmatic legitimacy, Petrobras can manipulate the environment, ensuring the compliance of the constituents to their technical and institutional demands. Enterprises, in turn, respond to the demands through compliance with technical demands, mainly through the certification of processes, and cultural changes. There aren t clear gains related to the transaction costs, however, gains in legitimacy can be seen as a cumulative capital that can serve as a competitive differential that generates economic gains. In terms of theoretical findings, it was found that, due to its explanatory power for actions that are difficult to explain only in economic terms, Institutional Theory may be used as theoretical support concurrent with other theories. TCE model has limitations in explaining the program actions. In the case, it s emphasized that Petrobras doesn t seek only economic efficiency, but has in its mission the commitment to social development.

Relações entre mecanismos de coordenação e controle com desempenho organizacional: um estudo nas instituições públicas de ensino médio de Natal

This research aimed at relating coordination and control forms to organizational performance. The multicase study was applied in two public high schools: Centro Federal de Educação Tecnológica do Rio Grande do Norte and Floriano Cavalcanti. In order to accomplish these objectives, it was developed a qualitative analysis and considered coordination and control forms of several authors. Also was considered Sander´s (1984) model of organizational performance. The mentioned model considers two criteria to analyze organizational performance: one instrumental (efficiency and efficacy) and other substantive (effectiveness e relevance). The research attempts to show the importance of balancing these criteria in a way that effectiveness and relevance becomes more important at schools. It was proven that the use of bureaucratic coordination forms has the power to influence the evaluation on the instrumental technique. At the same time, it was observed that the use of mechanisms based on the autonomy of the school is related to efficiency and efficacy. The object of this research can be considered successful

A Internet como tecnointeração da aprendizagem: valorização da cultura e identidade juvenil

The present study investigates Internet as technological interaction in the school environment as a resource of the teaching-learning process. It aims to discuss the lack of synchronicity between proposals of educational access for Internet use and types of access and interaction applied by youngsters. For the development of this research, I resorted to a qualitative, descriptive and explanatory research focused on a group whose subjects are youngsters from eleven to fifteen years of age in a catholic school which belongs to a group of private teaching schools in Natal city, Rio Grande do Norte state. As methodological option it focus on a group and the observation of its participation, discourse analysis and ethnography, considering facts and data of the pedagogical practice concerning the focused theme, besides the attempt to know the youngsters everyday at school and the relationship between them and juvenile cultures. It recognizes the existence of two moments of the focused group: the first related to internet use like technological interaction; the second concerns to the way Internet is problematic as technological interaction in classroom learning. While contacting with youngsters, the study discusses the concepts of Media Environments, Culture, Identity, Network, Consumption and Citizenship. It recognizes that it is relevant for the school to consider Internet a pedagogical tool, directed not just at research, but mostly as learning environment and as learning construction in a collaborative way. It points out the need of approach between school and media environment, reevaluating the pedagogical practice, offering a new evaluation proposal (self-evaluation). It suggests a renewal in the teacher's pedagogical practice in the classroom and using Internet, valuing the connection between technological interaction and communication as motivation elements of student s learning construction and their effective participation in decisions involving citizenship. It gives priority to educational work directed at the establishment of dialogic relationship between codes, learning and contents, leading to the new findings domain in the media environment, enabling the development of abilities and performances directed at the recognition and consumption of information from a critical reading of the media

Intencionalidades e práticas na construção de metodologias o CEFET-SE

Successive curricular changes that occurred in professional education altered pedagogical practices, and these practices being developed by means of integrating projects, at Centro Federal de Educação Tecnológica de Sergipe (CEFET-SE), between 2001 and 2003, originated some questions which became the study object of this thesis. We search for theoretical support mainly in GEPEM research (GEPEM/UFRN) works and practices in order to analyze elements that emerged from this pedagogical practice. To do so, we take as main reference the research of qualitative approach. We developed documents analysis, interviews, considering three aspects: the scenery where these changes took place, the conception and implementation of the Integrating Projects for what, we ask support in pedagogy of projects studies and principles of interdisciplinary, and contextualization as curriculum structuring elements. This research brought out some difficulties, conflicts and possible consensus in developing the methodological strategies for the Projects. In this process of coexistence of the traditional and the new, of an unavoidable distance between what was thought and what was effectively done, elements for a new pedagogical practice emerged. This could be noticed in terms of participative work, formative moments, teacher s autonomy related to the pedagogical work. A new door could be open to the possibilities of taking conscience of accepting the differences and oneself autoexperimentation. These are the possibilities that make men, not being mere information deposit, can dialog and transform, producing his existence by this means. In the present case, the existence of being teacher, the build himself in the time of possibilities

Políticas de educação profissional técnica e de ensino médio no Brasil: a implementação no CEFET-RN (1998 2008)

This study has analyzed the high school and professional education policies (1998-2008) and their impacts on the Centro Federal de Educação Tecnológica do Rio Grande do Norte. It has presented an analysis and design of the productive restructuring process in the world of work and education, the technical, vocational education and high school policies in Brazil, referring to this period, as well as the changes in Cefet-RN for implementation of Political Guidelines of Vocational, Technical and High School Education. This study is guided by assumptions related to these policies, which are located in different historical moments. It is a study in which subjects are understood as historical and social beings, embedded in the economic, political and cultural rights which, by its actions, can be transformed. It was based on a theoretical framework consistent with the object of research to give it shape and meaning, serving as a parameter to address the problem outlined in research questions. It was used analysis of bibliographical material and specific documents from the Institution, semi-structured interviews with the subjects part of technical and high school. Results show that many of the recommendations in the present high school policies and vocational technical and high school education, implemented in Cefet-RN, for the period 1998-2002, show inconsistencies between what is said and what can be officially established in the pedagogical practice of teachers and professional practice of some graduates. Regarding the integration of vocational education with the high school (2005-2008) in this Institution, the study signaled that its prioritization failed to materialize in full, in Cefet-RN, although it was developed and implemented a Political-Pedagogical Project in 2005

Em busca de novas territorialidades pedagógicas para a identidade da Educação Física no Ensino Médio integrado: uma perspectiva pós-crítica

Cet étude s agit du domaine de l Éducation Physique comme composante curriculaire dans le contexte de l Ensino médio integrado (l enseignement secondaire professionnel intégré) dans le IFRN, Campus Natal Zona Norte (Régio Nord). Son objectif principal est sur le plan éducatif des actions de l enseingant au procès des convivialités avec la culture corporale à partir des expériences, désires, besoins et volontés des apprenants dans la perspective de l imersion dans le monde de la créativité, de la recherche, de la connaissance et de la transformation de l identité pédagogique de la composante curriculaire. Dans ce sens, l étude a eu comme objectif l élaboration d une propisition pédagogique, fondamentée sur la Théorie Post-critique de l éducation qui contribue pour la configuration de l identité de l Éducation Physique dans les cours téchniques intégrés de niveau secondaire. La recherche s est configuré dans une intervention pédagogique fondamenté sur les préssuppositions methodologique d une expérience empirique du genre recherche-action apliqué dans l univers scolaire des cours thécniques intégrés de l enseignement secondaire de l IFRN, Campus Natal Zona Norte. Les sujets qui ont participé de la recherche, sont les apprenants des groupes de la première année du cours de Commerce et Éléctronique de la soirée (13h à 18h), inscrit à partir de l année 2012. Les instruments utilisés pour la recherche ont été deux questionaires et une cahier de bord. Les résultats obtenus sont disposés dans des graphiques qui représentent les paroles des sujets après le procès d intervantion et les analyses réalisées sous l étude-recherche, qui ont été faites por l analyse de contenu, de l image principale de la population recherchée. On considère que les résultats de la recherche ont été plausibles à la mesure que au-delà du support et de la participation dans la recherche, les réponses obtenues ont démontré que le procès d intervantion pédagogique a été pertinent pour les apprenants des cours téchniques intégrés de niveau secondaire de Commerce et Électronique de l IFRN, Campus Natal Zona Norte. Le sense essentielle de cette thèse s est concentrée dans la dimension interculturelle pour l Éducation Physique dans le secondaire intégré, comme un travail fondamenté à partir des temoignage des apprenants et par la conception post-critique du curriculum qui refuse les explications évidentes et instituées comme des véritées finales dans l objectif de réguler et controler les sujets de l éducation. L option faite par cet abordage de thèse a été pour rompre avec l établi à partir de la proposition d un dialògue, avec les apprenants, à la recherche de nouveaux territoires pédagogiques pour l Education Physique à l enseignement intégré de l IFRN, Campus Natal Zona Norte. Des territoires qui occupent des espaces dans la culture scolaire, dans une dynamique dialogique avec les apprenants, qui se défine politique et pédagogiquement pour la diversité culturelle du mouvement, qui aborde le concept de mouvement dans la proximité des actions corporales cotidiennes et qui propose de nouvelles possibilités et de recréations pour les pratiques de la culture corporale. La perspective post-critique ouvre des possibilités pour de nouvelles langages en fortifiant les narratives de ce qui ont toujours entendu et cependant ont silencié ses voix et ainsi, la thèse a confirmé que, l étude présent et la recherche supporté par la théorie post-critique du curriculum ont possibilité une nouvelles configuration pour l identité pédagogique de l Éducation Physique dans la condition de composant curriculaire des cours téchniques intégrés de niveau secondaire de l IFRN au Campus Natal Zona Norte

O Fundef e o Fundeb como política de financiamento para a valorização do magistério: efeitos na carreira e na remuneração dos professores da rede pública estadual de ensino do RN

Le présent étude analyse les effets de la politique de financement de l éducation de base, par les Fonds contables, Fundef et Fundeb, et sa proposition de valorisation de l enseignement, en considerant les dimensions de la carrière et de la rémunération des professeurs de l éducation publique de l état du Rio Grande do Norte, entre les années de 1996 et 2000. Pour comprendre les contraintes de l évaluation des politiques publiques, en cherchant aussi les contribution en Marx (1996) selon qui « le concret est concret » et que la dialétique du concret peut appuyer pour la tentative de capter le fenomène étudié. On a utilisé encore le référentiel bibliographique relatif au financement de l éducation et la valorisation de l enseignement à partir de la littérature reférente aux dimensions de l objet (Fundef et Fundeb) et (carrière et rémuneration). Dans la recherche documental, au-delà des législations, directrices nationales et locales pertinentes, se sont utilisés des donnés référents aux ressources, disponibles à la Finbra, Trésor National, SIOPE/RN, INEP/MEC, des informations du résumé de la feuille et feuille de payement du Secrétariat d État, de l Éducation et de la Culture (SEEC) et 289 bulletins de salaire de 21 professeurs. On a réalisé interview semi structurée avec une quantité de 9 professeurs, reférent à la carrière, et un questionaire appliqué à 12 professeurs relatif à la remuneration. On considère que sur les résultats reférents aux indicateurs éducationnel, dans la période Fundef il y a eu une réduction des inscriptions aux écoles de l état comme aussi aux fonctions des professeurs de l Enseignement Fondamental, et cela correspond à 37%. À partir de la vigence du Fondebe (2007 - 2010) ces indicateurs ont équalisé. Pendant toute la période, 1996 et 2010 il y a eu une augmentation des inscriptions de 119,03%, et aussi aux fonctions des professeurs de 77,44%. Par rapport aux informations de financement, on a constaté que, du minimum exigé (60%) sur l aplication des fonds à la rémuneration de l enseignant, on applique pour la période des deux fonds, plus que le minimum exigé, c est-à-dire de 83,29% à 98,89% des fonds. Les effets des fonds sur la carrière des 9 professeurs n ont pas été satisfactoires, si l on considère la promotion et la progression. Au cas de la promotion des 9 de ces professeurs, un seul a évolué son niveau (les titres) mais a, au même temps, rétroagit dans sa progression. Pour la progression des 9 professeurs, 8 d entre eux ont sa progression retardée, ce qui correspond à entre 2 et 5 classes, et ce qui provoque un préjudice qui varie entre 10% à 45% sur sa remunération. La différence d une classe à l autre correspond à 5% de son salaire. On évalue que les avantages financières contribuent pour la remunération avec un pourcentage plus élevé que son salaire, ce qui diminuent pendant lo Fundeb. Par rapport à la remunération un professeur de 24 ans de service avec formation, n arrive même pas à gagner 2 salaires minimums. Le professeur de 30 ans de service, maître, reçoit un salaire, en 2010, qui correspond a moins de 3 salaires minimums, c est-à-dire, une proportion de 2,82 et une remuneration qui correspond à un peu plus que 3 salaires minimums, c est-à-dire, une proportion de 3,66. L enseignement n est pas très favorisé si on le met face à d autres profession qui ont aussi l exigence de formation supérieure, ce qui provoque un effet négatif pour voir l enseignement comme profession. À propos des effets sur la rémuneration, on conclue qu il y a eu une amélioration mais encore insufisante, surtout si l on compare au Salaire Minimum annuel. On évalue que les fonds Fundef et Fundeb n ont pas été capables de promouvoir la valorisation de l enseignement dans le contexte de carrière et rémuneration. On observe quelques résultats négatif dans la politique de fonds, une fois qu il y aurait en avoir avec l incapacité de tel politique en promouvoir la dite valorisation de l enseignement, ce qui est une des causes, le financement avec des restriction budgétaire

O PROEJA ensino médio no ifrn, campus Caicó: causas da desistência e motivos da permanência

This dissertation deals about the theme of National Integration Program of the Professional Education to the Basic Education in the form of Youth and Adults Education - PROEJA, which was developed at the Federal Institute of Education Science and Technology of Rio Grande do Norte - IFRN - Campus Caicó. It aims to analyze the causes of the abandonment and the reasons for the permanence of students within the mentioned program. To substantiate this research, we used methodologically, some procedures such as bibliographical research, documentary analysis, semi-structured interviews and focus group. To analyze the data, we discussed the contradiction that involves duality and educational compensation based in the struggles and achievements of rights at the core of public policies for high schools, for vocational education and the education of youth and adults in the 2000s. We analyze the integrated high school under PROEJA, having as reference the conception of the total human formation; the inseparability of the primary education system and vocational education and the integration of knowledge and expertise as a whole, discussing the specificities of the modality EJA, discussing the causes of abandonment and the reasons for the permanence of the students of education for youth and adults (EJA) in the primary education system. As for the results, we found that although the PROEJA be a program that aims to provide a complete human formation to contribute to the full citizenship of their graduate members, what is announced in the document that guides its creation has not been materialized in Caicó Campus. The curriculum of the course was not designed for the students of EJA, nor teachers have had an adequate training to work with these specific individuals, and its specificities of being workers with differentiated learning times have not been considered. In addition, the courses are predominantly of instrumentalist characteristics. This indicates that the material and institutional conditions to achieve the promised total and complete training have not being fully materialized at the researched school. Associated with the difficulties concerning the intra-school and extra-school conditions, personal and socioeconomic conditions which are related to the obligation to work that implies in limitations to balance work, school and family, they influenced in the interruption of the school trajectory of these subjects. Through research, we confirmed that the motives of students who remain have to do also with intraescolares conditions the quality of education (qualification of technical staff and teachers) involved in the educational process, as well as socioeconomic and personal issues represented by the support of colleagues and family.Then it is concluded that the causes of abandonment and the reasons of the permanence are of institutional, socioeconomic and personal origins. Finally, it is observed that capitalist society demands as much as possible high levels of educated workers, and at the same time makes difficult the access to that education for much of the population, and it is not randomly. The objects of that exclusion are the popular worker classes and their children

PROEJA FIC/Fundamental no IFRN-Campus Mossoró: das intenções declaradas ao funcionamento de um curso em espaço prisional

This research aims to analyze the FIC Course of Assistant Technician in Service Management and Quality, integrated to elementary education / EJA form developed by IFRN MO Campus between 2011 and 2013 in the form of a PROEJA FIC / AT ELEMENTARY SCHOOL LEVEL. We seek to understand the adhesion between the national guidelines postulated for the Program, established in PPC and mediations with the process conceived in the run of the course. Guiding by the socio-critical approach and the dialogical paradigm, the theoretical-epistemological mark is especially buoyed by the theoretical contributions of Ciavatta (2005) , Rock (2011) , Haddad and Di Pierro (2000), Freire (2005), Marx (1982), Ramos (2005), Frigotto; Ciavatta; Ramos (2005), Moura (2012), and also on education in prisons by Onofre (2007, 2011), Bueno (2007), Julião (2011) and Foucault (2001). We assume that an action that enables professional qualification as FIC courses articulated to the EJA in the context of education in prisons have conceptual, methodological, political and pedagogical implications for it focuses challenges, weaknesses and opportunities on the same area of education., We have developed four techniques of data collection based on procedures and tools of qualitative research, such as document analysis, a student survey, the conduction of focus groups with teachers and administrators of the course and on-site observation. Mediated by the investigated context, results showed that the consolidation of PROEJA FIC / AT ELEMENTARY SCHOOL LEVEL goes beyond the intentions officially declared. It is inferred that after seven years of its creation, even though it keeps some potential, this program is not being satisfactorily developed and it shows weaknesses national and locally, it is set at low capillarity, it has a limited scope, and dissolved essential public commitments to the course development. The effectiveness of PROEJA FIC / AT ELEMENTARY SCHOOL LEVEL as part of an emancipatory inclusion social policy, according to official statement, entails approximating the legal logic with social logic, so as not only to propagate discourses and enforce worship to specific and successful experiences that reach only a minority, but to provide actual and necessary conditions to promote the breadth and social quality of the offered deals in this program format

Revelações e contradições entre concepção e gestão do currículo em um curso técnico no IFRN, na modalidade de educação de jovens e adultos

This dissertation reports the results of a research which has aimed to analyze the senses attributed to the curriculum by the students of the Technical Course of Computation Maintenance and Support, organized through the Programme of Integration of the the Professional Education with the Basic Education in the Youngster and Adult Education Modality (PROEJA), at Instituto Federal do Rio Grande do Norte (IFRN), Campus Santa Cruz. It has been sought to know who the students are and to investigate their curriculum conceptions, on which the this investigation has been based on. Thus, those senses attributed by the students on their narratives have been compared to the official proposed curriculum for the Programme and to the curriculum implemented by IFRN. The current research follows the qualitative approach being led by a study case and life stories methods. In order to effective that approach, two data collecting instruments have been developed: questionnaires and semi structured interviews. The collected data has been complemented by the legal and institutional documents analysis. This study is derived from the presupposition that PROEJA s students, although are able to access school after the educational system restructuration, are still facing difficulties during their courses because of the excluding and traditional curriculum, decontextualized with their personal and work life, that is, without curriculum integration. This study has accomplished PROEJA s students characterization presenting important data for the integrated curriculum construction at IFRN and revealing that the students consider the Programme as inclusive. Nevertheless, the practices concerned to the democratic construction of the curriculum and its dialogical action indicate partial inclusion, considering that, in order to include those students indeed, it would be necessary to include them to the institutional and academic context. Contradictory situations have been detected on the course pedagogical project, considered traditional and decontextualized, especially regarding to methodological aspects. The research also allowed to increase PROEJA s investigation field as well as to contribute with a better implementation of the Programme as curricular proposal bonded to Basic and Professional Education in the Youngster and Adult Modality Education Modality

Avaliação de desempenho em mercados reguladores de transporte urbano por ônibus :proposição de um modelo aplicável ao caso de Natal

Increased competition in the market of urban transport, characteristic of the Brazilian cities from years 90, has required actions of the managing agencies to ensure the universality of service, enhancing efficiency and consumer welfare. It grows in the Brazilian municipalities, the need to adopt a systematic performance evaluation in terms of management system of indicators and targets appropriate to the regulatory context, which has the purpose of evaluating the accomplishment and compliance by dealers, of the services granted during the contract period, marked by increasingly long periods. The introduction of an index operational performance in permission contracts/concession in urban buses is intended to establish a regulatory performance, giving the contract a pro-competitive feature and to allow the managing agency the systematic and continuous monitoring of the performance of the delegated service to avoid major deviations from desired performance. A performance assessment model of public transportation companies by bus, and applicable to the case of Natal is proposed. Sought to add the particularities found in the transport system in order to assess the performance of enterprises, contribute to improving the service quality to the population and enable decision-makers a detailed knowledge of the behavior of the licensees

Uma avaliação comparativa de estratégias de arranjos físicos para estaleiros de construção de embarcações metálicas de pequeno porte

The present study aims to analyse, in different levels of demand, what is the best layout strategy to adopt for the small metallic shipbuilding. To achieve this purpose, three simulation models are developed for analyze these production strategies under the positional, cellular and linear layouts. By the use of a simulation tool for compare the scenarios, Chwif and Medina (2010) and Law (2009)´s methodologies were adapted that includes three phases: conception, implementation and analysis. In conception real systems were represented by process mapping according to time, material resources and human resources variables required for each step of the production process. All of this information has been transformed in the cost variable. Data were collected from three different production systems, two located in Natal RN with cellular and positional layouts and one located in Belém-PA with linear layout. In the implementation phase, the conceptual models were converted in computacional models through the tool Rockwell Software Arena ® 13.5 and then validated. In the analysis stage the production of 960 ships in a year vessels were simulated for each layout noting that, for a production of until 80 units positional layout is the most recommended, between 81 and 288 units the cellular layout and more than 289 units the linear layout

A Informática como recurso didático para a aprendizagem de Física no ensino médio

The accomplishment of this work was motivated by our concerns, while teacher of Physics discipline, in the medium teaching and in the higher education, where we have been observing a lot of difficulties in the students' acting, to the they try to give pursuit out to their studies of the classroom, because of the lack of appropriate equipments, or even, of a laboratory where they can put in practice the studied contents. The work aims at to build and to test an educational software that it serves as tool auxiliadora in Physics learning in the Medium Teaching, in the area of electricity, with emphasis in the study of the electrodynamic in resistors. The developed software comes as an alternative to the learning problems, putting the computer science as auxiliary tool, because, besides being an alternative in the middle of the technological expansion, endowed with several resources, it stimulates the significant learning, according to David Ausubel's perspective. A software containing a program destined to the applicability of physics contents in the branch of the electricity is presented as an auxiliary tool, where the student can, not just, to review the contents presented at room, as well as for in practice, through a virtual laboratory, some of these contents, besides testing their knowledge through a bank of discursive subjects. The evaluation of the developed software was made submitting him/it to the professionals' of physics area appreciation. Equally, through continuous evaluations, they were made comparisons among the students' of five different groups acting, in the same school, that you/they were used of the program as tool of his auxiliary learning, and the acting of those that didn't use it

A desistência de alunos na licenciatura em física no Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte (IFRN): causas e sugestões para o combate

This dissertation proposes studying the issue of withdrawal undergraduate in physics at the Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte (IFRN) and collaborate with suggestions for dealing with this problem. The first chapter begins with an overview of two significant problems in the Brazilian educational system: the high dropout rates in degrees in physics and the lack of teachers with specific training in this science. Then, we discuss the relevance of this research to the area of physics teaching, as well as justify its completion as part of a professional master's degree. After, we present a proper definition for the term withdrawal, which is based on the existing problem in the IFRN. And, in the same chapter, we explicitly the focus, the objectives and the methodological aspects of this work. The results obtained in our investigation are presented in next four chapters. In the second chapter of this dissertation, we present: a brief history of the creation of IFRN degree in physics, the functioning of this course and the foundation of classrooms 2004.2 and 2006.1. We also show a kind of map of the withdrawal of the groups investigated (the dropout rate was 84.4% in both groups) and an analysis of the relationship between the curricula of each of them and the number of dropouts. In the third chapter, we display a descriptive statistics of the students which dropout and found that the largest dropout occurred with students who are women, married, parents of one kid; workers, joined with a minimum age of 23 years and completed high school at least 6 years. Then in the fourth chapter, we reveal and discuss the students' reports on the causes of their dropout. From the data presented, we can say that the answer to the question "What was the main reason for your dropout?" Is mainly in personal injury claims: another option for upper-level course and lack of time to devote to the course. In the fifth chapter, we show the results related to teacher s opinions about the phenomenon in question. We detected three main causes for the abandonment, according to teachers: the lack of dedication, the lack of interest and lack of integration in the course. In the sixth and final chapter, we discuss the results and present our conclusion and the proposed report - the product of this dissertation, presented as Annex. This report contains mainly suggestions for curricular and institutional actions that can contribute to reducing the dropout degree in Physics in the IFRN. The main actions suggested are: implementation of the curriculum in disciplines, implementation of programs or actions to combat this poor content of basic training, implementation of specific programs or actions for the student worker, and dissemination of IFRN degree in physics in schools through seminars or workshops
