M?TODOS: O trabalho compreendeu duas fases: I) desenvolvimento do simulador inovador e II) ensaio controlado comparando o desempenho do dispositivo ajust?vel ao corpo em rela??o ao simulador comercial no treinamento da habilidade de pun??o venosa no membro superior. Alunos da gradua??o do curso de medicina da UFRN (n=56) participaram da fase de interven??o, que foi constitu?da de pr?-teste, aula te?rica sobre acessos venosos perif?ricos, randomiza??o em grupos conforme o simulador utilizado para treinamento (Grupo Simulador Comercial e Grupo Simulador Inovador), pun??o real interpares, p?s-teste e question?rios de satisfa??o. RESULTADOS: Os Grupos Simulador Comercial e Simulador Inovador n?o tiveram diferen?a estatisticamente significativa quanto ? idade, sexo, cor, resultados do Pr?-teste e P?s-teste, avalia??o atitudinal e desempenho na execu??o da pun??o real. Os alunos do Grupo Simulador Experimental tiveram melhor desempenho no preenchimento do prontu?rio simulado. Ao t?rmino da pesquisa, o ganho cognitivo (conhecimento) teve significativo incremento em ambos os grupos. O grau de realismo, na percep??o dos alunos, foi equivalente em ambos os grupos. O grau de valor para o ensino do simulador inovador foi conceituado como bom a ?timo em 85,7% dos alunos que o utilizaram. CONCLUS?ES: Diante dos resultados obtidos, o simulador inovador demonstrou-se como uma alternativa de baixo custo para o ensino da habilidade de pun??o venosa em membro superior, onde o desempenho cognitivo, procedimental e atitudinal dos alunos que o utilizaram foi equivalente ao dos que treinaram em simulador comercial. / OBJECTIVE: To dev elop and evaluate the use of a body adjustable device for training of peripheral venous catheterization for healthcare undergraduate students . METHODS: This study involved two phases: I) development of the innovative simulator and II) a controlled trial co mparing the performance of the body adjustable device in relation to the commercial simulator for the training of venipuncture skills. A total of 79 first - year medical students participated in the intervention phase, which consisted of pretest assessment, lecture on peripheral venous access, randomization into two groups according to the simulator used for training (Commercial Simulator and Experimental Simulator), real venipuncture procedure, post - test assessment and evaluation of satisfaction. RESULTS: Gr oups were homogeneous in age, sex, pre - test and post - test scores, attitudinal assessment and performance in performing the real venipuncture. Students from the Experimental Simulator group performed better on the filling of simulated records. At the end of the study, cognitive gain significantly increased in both groups. The degree of realism perceived by students was equivalent for two groups. A total of 85.7% of students rated the Experimental Simulator as good or excellent. CONCLUSIONS: Experimental simu lator proved to be a low cost alternative for the training of venipuncture skills in upper limb. The cognitive procedural and attitudinal performances of students who used the experimental simulator were similar to those observed in the group trained with commercial simulator.

Promo??o do aprendizado, recurso de aprendizado, sistema de feedback entre professor e aluno e meio de avalia??o e acompanhamento do desempenho dos alunos ao longo de sua forma??o s?o as vertentes principais dessa ferramenta. OBJETIVO: Avaliar a utilidade dos mapas conceituais como ferramenta de ensino-aprendizagem na forma??o de estudantes de gradua??o do curso de medicina da UFRN. METODOLOGIA: Estudo intervencional, seccional, randomizado, realizado com estudantes de medicina dos 3? e 5? per?odos do curso de medicina da UFRN, durante o semestre acad?mico 2014.2, totalizando 86 participantes, agrupados em dois grupos: GI (interven??o) e GII (controle) em cada semestre acad?mico. RESULTADOS: O uso de mapas conceituais para ensino da s?ndrome de Insufici?ncia Hep?tica resultou em ganho cognitivo, estatisticamente significante, para os alunos do GI, do quinto per?odo (GI: 6,8?1,6 e 8,0?1,5, p = 0,024; GII: 7,2?2,1 e 8,0?1,7, p = 0,125, m?dias pr? e p?s-interven??o, respectivamente), fato n?o observado no terceiro per?odo (GI: 7,7?1,3 e 8,0?1,4, p = 0,501; GII: 6,7?1,8 e 7,8?1,8; p = 0,068, m?dias pr? e p?s-interven??o, respectivamente). A maioria dos estudantes n?o conhece a ferramenta (53,8% do terceiro per?odo e 65,3% do quinto per?odo). Dentre os que conhecem os mapas conceituais, a maioria (59,3%) somente a utilizaram durante o ensino m?dio, 14,8% nunca a haviam utilizado e apenas sete alunos (25,9%) a utilizam durante o curso de Medicina. CONCLUS?O: Apesar do pouco conhecimento da ferramenta, a boa aceitabilidade e compreens?o da mesma pode ser observada entre os participantes do estudo. Entretanto, faz-se necess?ria a an?lise de outros dados como o conhecimento do estilo de aprendizagem desses alunos, especialmente do terceiro per?odo, para entendermos melhor sua rela??o com a melhoria do desempenho cognitivo. / BACKGROUND: Among the wide range of skills displayed by a medical doctor is undoubtedly the need to use cohesive and well grounded clinical reasoning in order for medical care to be indeed effective. It is in this respect that conceptual maps emerge; these are a methodological innovation that allows a comprehensive, panoramic and associative outlook of theoretical content, making it more practical and applicable to the reality of clinical observation. Promoting learning, learning resources and a feedback system between professor and students, as well as assessing and monitoring the performance of students during their academic training, are the main features of this tool. OBJETIVE: Assess the use of conceptual maps as a teaching-learning tool in the training of undergraduate medical students at Universidade Federal do Rio Grande do Norte (UFRN). METHODOLOGY: Interventional, randomized, cross-sectional study conducted with students from the 3rd and 5th periods of the medical course at UFRN, during the second semester of 2014, totaling 86 participants, divided into two groups: GI (intervention ? clinical case resolution with a conceptual map) and GII (control ? clinical case resolution without a conceptual map) in each period. RESULTS: The use of conceptual maps to teach liver failure syndrome resulted in a statistically significant cognitive gain for G1 students from the 5th period (GI: 6.8?1.6 and 8.0?1.5, p = 0.024; GII: 7.2?2.1 and 8.0?1.7, p = 0.125, pre and post-intermediate means, respectively), a result not observed in the period 3rd (GI: 7.7?1.3 and 8.0?1.4, p = 0.501; GII: 6.7?1.8 and 7.8?1.8; p=0.068, pre and post-intermediate means, respectively). Students in the 3 rd period gave better responses to the first clinical case, with a larger number of suitable concepts and crosslinks, when they used conceptual maps (GI: 91.3?13.15 and GII: 64.84?22.84, p=0,002). Students in the 5th period exhibited better clinical reasoning and more complete responses using the tool (p=0,01). Most of the students were not aware of the tool (53.8% from the 3rd period and 65.3% from the 5th period). Among those who knew about conceptual maps, most (59.3%) had only used them during high school, 14.8% had never used them and only seven students (25.9%) used them during the medical course. Analysis of open responses, obtained in process assessment showed clear satisfaction and enthusiasm with learning about the new tool, and frequent suggestions to use it at other moments in the course. Assessment of learning profile, using the VARK questionnaire, showed that most students from both periods exhibited a multimodal style. CONCLUSION: Despite their scant knowledge regarding the tool, good acceptability and understanding was observed in the study participants. The conceptual maps allowed cognitive gains, better responses and clinical reasoning in teaching liver failure syndrome to 5th period students.

A sua alta taxa de mortalidade est? relacionada com detec??o da patologia em est?gios avan?ados. De acordo com a literatura, a tomografia computadorizada (TC) ? a modalidade de imagem mais indicada para a detec??o precoce de n?dulos pulmonares. No entanto, ela impacta diretamente na carga de trabalho dos radiologistas. Pesquisadores propuseram v?rios sistemas automatizados para auxiliar os radiologistas na detec??o do c?ncer de pulm?o. Entretanto, a utiliza??o desses sistemas necessitava de altera??es no fluxo de trabalho cl?nico e altos custos de implanta??o. Visando solucionar estas barreiras, o presente trabalho prop?e uma nova abordagem para detec??o de n?dulos pulmonares, em exames de tomografia computadorizada (TC), baseado no descritor Histograma do Gradiente Orientada (HoG) e M?quina de Vetor de Suporte (SVM). Al?m disso, ? proposto uma aplica??o desta abordagem num sistema de telerradiologia, chamado LCD-OpenPACS, gratuito e c?digo fonte aberto. Este sistema ? uma extens?o do sistema OpenPACS que ? um sistema de comunica??o e arquivamento de imagens m?dicas que possui c?digo fonte aberto e multiplataforma desenvolvido pelo Laborat?rio de Inova??o Tecnol?gica em Sa?de (LAIS) do Hospital Universit?rio Onofre Lopes (HUOL). O m?todo proposto ? formado por cinco etapas: aquisi??o das imagens, segmenta??o, detec??o de n?dulos suspeitos, extra??o das caracter?sticas e classifica??o (elimina??o de falsos positivos). O m?todo proposto foi validado com 100 n?dulos (identificados por, pelo menos, dois radiologistas) e 101 n?o n?dulos (por exemplo, tecido, vasos sangu?neos e outras estruturas que n?o representavam n?dulos cancer?genos) e apresentou uma sensibilidade de 98,03% com 9,6 falso positivo por caso em 0,18 s. O sistema detectou n?dulos pulmonares cancer?genos (solit?rios, opacidade em vidro fosco e n?dulos justavascular) entre 3 mm e 30 mm. Entretanto, a etapa de segmenta??o do sistema ainda n?o est? apresentando resultados satisfat?rios na presen?a de n?dulos justapleurais e outras patologias graves que alteram a opacidade dos contornos pulmonares. As principais contribui??es do presente trabalho foram o desenvolvimento do novo m?todo de detec??o de n?dulos pulmonares e a proposta do sistema de telerradiologia que minimiza as altera??es do fluxo de trabalho cl?nico e o custo de implanta??o, podendo ser utilizado pelo sistema de sa?de brasileiro (SUS). Ainda s?o necess?rias mais pesquisas para aperfei?oar o sistema proposto, principalmente melhorar o processo de segmenta??o das imagens pulmonares. Como trabalhos futuros, propomos mensurar caracter?sticas dos n?dulos (por exemplo, malignidade e volume), avaliar a evolu??o do tratamento oncol?gico e seu poss?vel progn?stico. / Lung cancer is one of the most common types of cancer and has the highest mortality rate. Patient survival is highly correlated with early detection. Computed Tomography technology services the early detection of lung cancer tremendously by offering aminimally invasive medical diagnostic tool. However, the large amount of data per examination makes the interpretation difficult. This leads to omission of nodules by human radiologist. This thesis presents a development of a computer-aided diagnosis system (CADe) tool for the detection of lung nodules in Computed Tomography study. The system, called LCD-OpenPACS (Lung Cancer Detection - OpenPACS) should be integrated into the OpenPACS system and have all the requirements for use in the workflow of health facilities belonging to the SUS (Brazilian health system). The LCD-OpenPACS made use of image processing techniques (Region Growing and Watershed), feature extraction (Histogram of Gradient Oriented), dimensionality reduction (Principal Component Analysis) and classifier (Support Vector Machine). System was tested on 220 cases, totaling 296 pulmonary nodules, with sensitivity of 94.4% and 7.04 false positives per case. The total time for processing was approximately 10 minutes per case. The system has detected pulmonary nodules (solitary, juxtavascular, ground-glass opacity and juxtapleural) between 3 mm and 30 mm.

From this method got up a layer of aluminum oxide on the anodic metal, who presented the basic properties necessary for the application as a support for the production and acquisition of nanomaterials, such as porosity nano and resistance to high temperature, and other properties, as resistance to corrosion, and chemical, high ranking of the structure and pore size of the pores. The latter, ranging from 10 to 100nm depended on the electrolyte used, which in this study was the H2SO4. To remove all remaining aluminum, it is a bath of dissolution with HCl and CuCl where the residual aluminum has been withdrawn, and the deep pores were opened after chemical treatment with NaOH. After the dissolution, the membranes were calcined at temperatures of 300, 600 and 900? C, and sintered at temperatures of 1200 and 1300? C to win mechanical strength, porosity and observe the desired crystallization. Then went through analyses of composition through X-ray diffraction and morphology of the microstructure through a scanning electron microscope. The method was effective for obtaining alumine membranes applied in the processes of production of materials in nano / Trata de um estudo sobre a obten??o de membranas de alumina atrav?s do m?todo da anodiza??o.

Este ?ltimo, variando de 10 at? 100nm dependeu do eletr?lito usado, o qual neste estudo foi o H2SO4. Para retirar todo alum?nio restante, procedeu-se um banho de dissolu??o com HCl e CuCl no qual o alum?nio residual foi retirado, e os poros profundos foram abertos ap?s o tratamento qu?mico com NaOH. Ap?s a dissolu??o, as membranas foram calcinadas nas temperaturas de 300, 600 e 900? C, e sinterizadas nas temperaturas de 1200 e 1300? C para ganhar resist?ncia mec?nica, porosidade desejada e observar a cristaliza??o. Em seguida passou por an?lises de composi??o atrav?s da Difra??o de Raios-X e morfologia da microestrutura por meio de um microsc?pio eletr?nico de varredura. O m?todo se mostrou eficiente para obten??o de membranas de alumina aplicadas nos processos de produ??o de materiais em escala nanom?trica

To overcome these problems means to be able in obtaining accurate geometry information of the limb and, consequently, better manufacturing processes of both transfemural and transtibial prosthetic sockets. The key point for this task is to customize these readings trying to be as faithful as possible to the real profile of each patient. Within this context, firstly two prototype versions (α and β) of a 3D mechanical scanner for reading residual limbs shape based on reverse engineering techniques were designed. Prototype β is an improved version of prototype α, despite remaining working in analogical mode. Both prototypes are capable of producing a CAD representation of the limb via appropriated graphical sheets and were conceived to work purely by mechanical means. The first results were encouraging as they were able to achieve a great decrease concerning the degree of uncertainty of measurements when compared to traditional methods that are very inaccurate and outdated. For instance, it's not unusual to see these archaic methods in action by making use of ordinary home kind measure-tapes for exploring the limb's shape. Although prototype β improved the readings, it still required someone to input the plotted points (i.e. those marked in disk shape graphical sheets) to an academic CAD software called OrtoCAD. This task is performed by manual typing which is time consuming and carries very limited reliability. Furthermore, the number of coordinates obtained from the purely mechanical system is limited to sub-divisions of the graphical sheet (it records a point every 10 degrees with a resolution of one millimeter). These drawbacks were overcome by designing the second release of prototype β in which it was developed an electronic variation of the reading table components now capable of performing an automatic reading (i.e. no human intervention in digital mode). An interface software (i.e. drive) was built to facilitate data transfer. Much better results were obtained meaning less degree of uncertainty (it records a point every 2 degrees with a resolution of 1/10 mm). Additionally, it was proposed an algorithm to convert the CAD geometry, used by OrtoCAD, to an appropriate format and enabling the use of rapid prototyping equipment aiming future automation of the manufacturing process of prosthetic sockets. / Devido aos avan?os no processo de fabrica??o de pr?teses ortop?dicas, a necessidade de uma melhor qualidade t?cnica na leitura da forma (i.e., com menos incertezas) da parte residual dos amputados tornou-se um desafio. Para superar esses problemas ? necess?rio ser capaz de obter informa??es precisas da geometria do membro e, consequentemente, melhorar os processos de fabrica??o de pr?teses e cartuchos transfemurais e transtibiais. O ponto-chave para esta tarefa ? personalizar essas leituras tentando ser o mais fiel poss?vel ao verdadeiro perfil de cada paciente. Dentro deste contexto, duas vers?es (α e β) de um prot?tipo de um scanner 3D mec?nico para ler forma residual de membros com base em t?cnicas de engenharia reversa foram concebidas. Prot?tipo β ? uma vers?o melhorada do prot?tipo α, apesar de ainda trabalhar em modo anal?gico. Ambos os prot?tipos s?o capazes de produzir uma representa??o CAD do membro atrav?s de apropriada planilha gr?fica e foram concebidos para funcionar exclusivamente atrav?s de meios mec?nicos. Os primeiros resultados foram encorajadores, uma vez que foram capazes de conseguir uma grande redu??o em rela??o ao grau de incerteza das medi??es quando comparadas com as dos m?todos tradicionais, que s?o muito imprecisas e desatualizadas. Por exemplo, n?o ? incomum ver estes m?todos arcaicos sendo usados utilizando fitas m?tricas caseiras para medir a forma da perna do paciente. Embora o prot?tipo β tenha melhorado as leituras, ainda ? necess?rio algu?m para introduzir os pontos plotados (i.e., aqueles marcados na planilha em formato de disco gr?fico) para um software acad?mico CAD chamado OrtoCAD. Esta tarefa ? realizada por digita??o manual, que ? morosa e tem confiabilidade limitada. Al?m disso, o n?mero de coordenadas obtidas a partir do sistema puramente mec?nico ? limitado ?s subdivis?es do disco gr?fico (ele grava um ponto a cada 10 graus com uma resolu??o de um mil?metro). Estes inconvenientes foram resolvidos na concep??o da segunda vers?o do prot?tipo β, na qual foi desenvolvida uma adapta??o eletr?nica, tornando-o capaz de realizar uma leitura autom?tica (i.e., sem interven??o humana no modo digital). Um software de interface (i.e., driver), foi desenvolvido para facilitar a transfer?ncia de dados. Resultados muito melhores foram obtidos significando menor grau de incerteza (ele registra um ponto a cada 2 graus com uma resolu??o de 1/10 mm). Al?m disso, foi proposto um algoritmo para converter a geometria CAD, utilizada pelo OrtoCAD, para um formato adequado e que permita a utiliza??o de equipamento de prototipagem r?pida destinado a uma futura automa??o do processo de fabrica??o dos cartuchos de pr?teses.

The structure, surface morphology and magnetic properties were investigated using X-ray diffractometry (XRD), atomic force microscopy (AFM) and vibrating sample magnetometer (VSM). XRD shows the formation of γ FeN phase and a combination of ζFe2N + ɛFe3N phases. The film s saturation magnetization and coercivity depends on morphology, composition, grain size and treatment temperature. Temperature raising from 250 ?C to 350 ?C were followed by an increase in saturation magnetization and film s surface coercivity on the parallel direction in relative proportion. This fact can be attributed to the grain sizes and to the different phases formed, since iron rich fases, like the ɛFe3N phase, emerges more frequently on more elevated treatment s temperature. Using this new and reasonably low cost method, it was possible to deposit films with both good adhesion and good magnetic properties, with wide application in magnetic devices / Filmes de nitreto de ferro, com centenas de nanometros de espessura foram depositados pelo m?todo de deposi??o/nitreta??o por Gaiola Cat?dica utilizando um plasma de N2/H2 sobre um substrato de vidro comum.

A magnetiza??o de satura??o e coercividade dos filmes de nitreto de ferro dependem da morfologia, composi??o, tamanho de gr?o e temperatura de tratamento. Com o aumento da temperatura de 250 para 350 ?C, a magnetiza??o de satura??o e a coercividade na dire??o paralela ? superf?cie dos filmes tamb?m aumentam em propor??o relativa. Isto pode ser atribu?do aos tamanhos de gr?os e ?s diferentes fases formadas, j? que fases ricas em ferro como ɛFe3N surgem com frequ?ncia maior em temperaturas de tratamento mais elevadas.

The qualitative theory of interpretation is used, observing the ethical and political positions of the various parts involved in the contractual process, seeking, from them, to understand in an interpretative way the decisions deriving from human nature, at first guided by social interests, as also political, and at what level the desired change was achieved. The analysis of the information collected is promoted through an integrative review of the literature, involving a descriptive deepening of the COAPES and its foundations; analysis of documents and instruments, such as minutes of meetings, letters, ordinances, decrees and laws; and the interpretation and discussion of the results, with the supervenient purpose of generating a product that presents relevance to other institutions interested in starting the process of contracting. The importance of the agreement, discussion and qualification of the insertion of students in the territory stands out during the contractual procedure. Procedural non-linearity is verified during the problematization, against the orientation present in the Unified Health System (SUS) guides, stagnating with the change in administrative management during and after the period of municipal elections. It is possible, then, to affirm that the COAPES production process under study still needs to progress as a dialogical process with recognition, commitment and participation of the involved actors, in a constant search for the qualification of health care in an integrated way to the process of in-service training and permanent education of the health network.

Contudo, n?o ? pac?fico, na doutrina, o entendimento acerca da natureza de tratado de direitos humanos de todas as Conven??es dessa Organiza??o. H? quem afirme, com base na Declara??o da OIT sobre os Princ?pios e Direitos Fundamentais do Trabalho, serem apenas oito aquelas consideradas tratados de direitos humanos; por outro lado, numa posi??o intermedi?ria, h? os que defendem serem tratados de direitos humanos apenas as Conven??es que desenvolvam direitos trabalhistas j? versados em outros instrumentos de direitos humanos. Nesse cen?rio, ? imprescind?vel identificar quais Conven??es da OIT podem realmente ser consideradas tratados internacionais de direitos humanos e quais as consequ?ncias disso no direito brasileiro. Para resolver a quest?o, na primeira parte do trabalho, busca-se compreender os movimentos de constru??o e reconstru??o dos direitos humanos, e a prote??o internacional de tais direitos, al?m de apresentar as dificuldades te?ricas que permeiam o estudo da mat?ria e fornecer um conceito de tratado de direitos humanos. Em seguida, faz-se o estudo da hist?ria e estrutura da OIT, al?m da forma??o das Conven??es e das teorias que as colocam como tratados de direitos humanos. Na terceira e ?ltima parte, analisam-se a hierarquia e a dualidade de rito de aprova??o dos tratados de direitos humanos no ordenamento brasileiro, antes de se analisar a corre??o do processo de incorpora??o das Conven??es da OIT sobre direitos humanos ap?s a EC n. 45/2004, a insufici?ncia do sistema recursal trabalhista para prote??o dos direitos humanos e a pouca relev?ncia dessas Conven??es na jurisprud?ncia do TST. Ao final, chega-se ? conclus?o de que nem todas as Conven??es s?o tratados de direitos humanos e mesmo as que s?o n?o v?m tendo tratamento adequado no Brasil. / In spite of great development of the Human Rights International Law, the conceptualizations of human rights treaties are vague and unprecise. In relation to ILO?s Conventions, there are three different chains in doctrine which refer to absolute inappropriate criteria to characterize them as human rights treaties, what makes things even more difficult. This problem may have resulted in the unconstitutionality of the internalization process of the Conventions approved since the 3th paragraph was included to article 5 of the Brazilian Constitution by the Amendment number 45/2004. Since the cited amendment entered into force, none of the six Conventions already approved by Brazilian Congress have been voted under the new procedure, indicating a possible unconstitutionality. Other problem related to que lack of adequate criteria to establish the correct nature of the Conventions is the possibility of violation of workers? human rights. Brazilian Superior Labor Court (TST) refuses appellations based on international treaties, even if they are ILO?s Conventions on human rights. In such scenario, it is as important to present elements to correct characterize ILO?s Conventions as human Rights treaties and to analyze the dimension give to them by Brazilian Constitution, as to study the process of internalization of such treaties, the legislation regarding treaties violations, and the importance of ILO?s Conventions on human rights to Brazilian Superior Labor Court (TST). The first part of the thesis is dedicated to the comprehension of the Human Rights. In the second chapter, we discuss the formation of ILO?s Conventions and their nature as human rights treaties. The third and last chapter, ILO?s Conventions situation in Brazilian Law System is analyzed. The thesis concludes that not all Conventions are human rights treaties; however, Brazilian Constitution is being disrespected in relation to ILO?s Conventions on human rights.

Assim, buscou-se analisar a experi?ncia do Curso de Medicina da UFCG-Cajazeiras, bem como: fazer um relato hist?rico do curso; analisar os desafios atuais; reconhecer os fundamentos te?ricos do PPC; descrever a inser??o da Sa?de Coletiva/MFC no curr?culo; analisar se esse PPC atende ?s exig?ncias da APS; descrever como os aspectos referentes ao mundo do trabalho, projeto pedag?gico, abordagem pedag?gica, cen?rios de pr?tica e desenvolvimento docente s?o vivenciados; reconhecer contradi??es entre PPC e condu??o real; e extrair generaliza??es que embasem pol?ticas p?blicas. A pesquisa localiza-se no quadro referencial marxista, utilizando m?todos de procedimento hist?rico, monogr?fico e comparativo, com abordagem qualitativa de car?ter descritivo e explorat?rio, tendo, como t?cnicas de coleta de dados, a Documenta??o Indireta (pesquisas documental e bibliogr?fica) e a Observa??o Direta Intensiva - observa??o participante, inicialmente assistem?tica e, posteriormente, sistem?tica, seguindo instrumento desenvolvido por Lampert; e, enquanto t?cnica de an?lise de dados, o m?todo hermen?utico-dial?tico. A hist?ria do curso revela a tens?o entre baixa capacidade de absor??o da rede de sa?de local e caracter?sticas institucionais da UFCG (corpo docente e PPC). O primeiro aspecto foi p?lo principal da contradi??o nos primeiros anos, parcialmente contornado com redu??o de entradas anuais, viabiliza??o do internato em outras institui??es e instala??o de servi?os hospitalares pr?prios. Somente ent?o o Desenvolvimento Docente ganha principalidade nos desafios atuais. Partindo de problem?tica comum ? Medicina Rural, o PPC apresenta grande ecletismo: flerta com o Materialismo Hist?rico-Dial?tico via Epidemiologia Cr?tica Latino-Americana, que fundamenta sua compreens?o da Medicina, e Metodologia da Problematiza??o, subjacente ? compreens?o do aluno como sujeito e ? diversifica??o dos espa?os de aprendizagem; referenciando-se na Pedagogia das Compet?ncias, dialoga com correntes de cunho racionalista, individualista e neopragmatista; e, finalmente, a P?s-modernidade de Contesta??o de Boaventura de Sousa Santos e o Pensamento Complexo de Edgar Morin fundamentam uma compreens?o ?tica do Ser Humano e da Ci?ncia, que norteiam os pressupostos de curr?culos baseados no humanismo e da pesquisa como eixo condutor do ensino. O curso est? alinhado ?s diretrizes da ABEM/SBMFC para o ensino na APS. Inserido desde o primeiro ano, com o ensino de abordagens coletivas do processo sa?de-doen?a, a forma??o na APS continua com ?nfase, a partir do quarto per?odo, na abordagem comunit?ria e familiar no territ?rio, dentro do qual se desenvolve a Resid?ncia em MFC e onde, nos anos intermedi?rios seguintes e no internato, treina-se abordagem da cl?nica individual na APS. Nesse percurso s?o trabalhadas metodologias diferenciadas, como viv?ncias, grupos tutoriais para acompanhamento de PTS, semin?rios, etc. O curso apresenta perfil Inovador com Tend?ncia Avan?ada, sendo o Desenvolvimento Docente seu ponto cr?tico, revelando sua contradi??o fundamental: avan?os no plano te?rico, mas que n?o s?o expressos totalmente na pr?tica. Conclui-se que as pol?ticas de interioriza??o do ensino m?dico deve priorizar a an?lise da rede de sa?de, e que mudan?as na Educa??o M?dica depende da a??o pol?tica, apresentando-se uma agenda de propostas. / Taking under consideration the medical education reform processes in recent years and the current debate on the transference of medicine undergraduate courses to the countryside, the need of studying the experiences that have arisen after the 2001 National Curriculum Guidelines is visible. As a result, it was sought to analyze the experience UFCG medicine school located in Cajazeiras, moreover, report the history of the course; evaluate the present challenges; consider the theoretical foundations of the Pedagogical Project of the Course (PPC); describe the insertion of Public Health / Family Medicine in the curriculum; consider whether this PPC meets the requirements of Primary Health Care; describe how the aspects related to the world of work, pedagogical project, pedagogical approach, practice scenarios and teacher development are experienced; recognize contradictions between PPC and real conduction; and excerpt generalizations that may support public policies. This research is based on Marxist frame of reference. Historical, monographic and comparative methods of procedure were used. It has a qualitative approach. Its characteristics are descriptive and exploratory. Indirect documentation (documentary and bibliographic research) and Intensive Direct Observation - participant observation, which, in the beginning was unsystematic and later systematic, following the instrument developed by Lampert, were adopted as data collection techniques. As data analysis technique, the hermeneutic-dialectic method. The story of the course reveals the tension between low absorptive capacity of the local health system and institutional characteristics of UFCG (teaching staff, PPC). The first aspect was the main pole of the contradiction in the early years, which was partially overcome thanks to the reduction of annual entries, possibility of supervised internships in other institutions and UFCG?s own hospital services establishment. Only then, the Teacher Development gained preeminence among the present challenges. Starting from common problems of Rural Medicine, PPC has a great eclecticism: it flirts with the Historical and Dialectical Materialism by Latin American Critical Epidemiology, which bases its understanding of medicine, and Methodology of Problematization, with the understanding of the student as a subject and diversification of learning spaces; referencing on Skills Pedagogy, conforms to currents of rationalist imprint, individualistic and neopragmatist nature; and, finally, the Postmodernism of Contestation, of Boaventura de Sousa Santos, and the Complex Thought, of Edgar Morin, establish an ethical understanding of the human being and Science, which guides assumptions of curricula based on humanism and research as a conductor axis of teaching. The course is aligned with the guidelines of ABEM / SBMFC for teaching in primary health care, which is inserted since the first year, by teaching of collective approaches of the health-disease process. Training in primary health care emphatically continues in the fourth term when community and family approaches in the territory are studied, developing Residency in Family Medicine and where, during the intermediate following years and the supervised internships, individual clinical approach in Primary Health Care is trained. Throughout the path, different methodologies are worked such as living in communities, tutorial groups for follow Singular Therapeutic Projects, seminars, etc. The course presents Innovative with Advanced Trend profile, and Teaching Development is a critical point, revealing their fundamental contradiction: the advancements in theory are not fully expressed in practice. It is both concluded that the medical educational policies of transference of the undergraduate course to the countryside should prioritize the analysis of the health network, and that changes in medical education depends on political action, presenting an agenda of proposals.

Soares. A pesquisa ? estabelecida a partir de leituras que tratam, sobretudo, da metafic??o par?dica, da escrita autopoi?tica, do humor enquanto arte das superf?cies, bem como da fabula??o de mundos por vir, fazendo uso de conceitos da filosofia da diferen?a em Deleuze e Guattari e da cr?tica liter?ria, principalmente, em Linda Hutcheon, Blanchot e Foucault, tais como: m?quina autopoi?tica, humor, fabula??o, metafic??o, par?dia, espa?o liter?rio e obra. No plano de composi??o, o romance do humorista brasileiro torna a sua realidade ficcional vis?vel pelo parodiar de obras liter?rias e historiogr?ficas, sobretudo as narrativas policiais doylianas e as que retratam o Rio Janeiro no final do s?culo XIX. Nesse sentido, desenvolve-se, nesta obra, uma escrita que se mant?m em si mesma, desloca significa??es e flagra sua realidade ficcional. No heterocosmo soareano, a narrativa se apresenta como num espa?o de uma biblioteca. O apelo da obra se encontra na convoca??o de estere?tipos apresentados em livros sobre a capital do imp?rio dos tr?picos, no final do segundo reinado, bem como em narrativas policiais. A repeti??o com diferen?a de livros e obras p?e em questionamento imagens arraigadas, abrindo espa?o para o ?flagrante delito? da fabula??o de mundos, que se constituem na superf?cie da escrita e que n?o se reduzem a sedimenta??es. / This thesis discusses and analyzes as the parodic metafiction, namely, the process that makes fiction visible by repetition with difference, enhances the creation of a different detective narrative in the novel A Samba for Sherlock (1995), by J? Soares. The research is established by readings which take into account mainly the parodic metafiction, the autopoietic writing, the humor as the art of surfaces, as well as the fabulation of worlds to come, making use of concepts of the philosophy of difference in Deleuze and Guattari and literary criticism, especially in Linda Hutcheon, Blanchot and Foucault such as autopoietic machine, humor, fabulation, metafiction, parody, space of literature and work. In the plane of composition, the novel of the Brazilian humorist makes its fictional reality visible, parodying literary and historiographical works, mainly the Doylian detective narratives, and work related to the Rio de Janeiro of the late nineteenth century. In this sense, this work develops a writing that remains in itself, displaces significations and sees its fictional reality. In Soares?s heterocosm, the narrative brings together the space of a library. The appeal of the work is in the convening of stereotypes presented in books on the capital of the empire of the tropics at the end of the second reign, as well as on detective narratives. The repetition with difference of books and works call into question deep-rooted images, making room for fabulation ?in flagrante delicto? of worlds that constitute the writing surface and not reduce itself to sedimentation.
