A influência do método pilates sobre a qualidade de vida em mulheres climatéricas

Objetivo: Avaliar a influência do método Pilates sobre a qualidade de vida em mulheres climatéricas atendidas pelo Sistema Único de Saúde. Métodos: Trata-se de um estudo prospectivo do tipo ensaio clínico randomizado, cego para avaliador, com amostra por conveniência, composta por 51 mulheres divididas em grupo controle (n=25) e experimental / Pilates (n=26), ao longo de 12 semanas. Os instrumentos usados para coleta foram: o Medical Outcome Study 36-item Short Form Health Survey (MOS SF-36 Health Survey) versão brasileira e o índice menopausal de Blatt e Kupperman. Os dados foram tratados com estatística descritiva e inferencial (teste t para amostra pareada e de Wilcoxon), com p≤0,05. Resultados: Observou-se que a amostra estudada apresentava idade média de 53,7±4,07 e 53,9±5,52 anos, IMC médio de 25,2Kg/m2±3,71 e 26,06 Kg/m2±2,56, no grupo controle e experimental, respectivamente. A maioria era casada, sem trabalho formal e com pelo menos o 2º grau completo. O grupo submetido ao método Pilates apresentou efeitos positivos sobre a diminuição dos sintomas climatéricos (19,6 para 12,2) com p= 0,001 (GE) e p=0,062 (GC), bem como apresentou significância estatística para comparação no parâmetro de capacidade funcional (p=0,001), limitação por aspectos físicos (p=0,05), dor (p=0,001), estado geral de saúde (p=0,001), vitalidade (p=0,001), aspectos sociais (p=0,027) e saúde mental (p=0,001) em mulheres na meia idade. Conclusões: Os resultados do estudo mostraram que 12 semanas de intervenção com o método Pilates apresentaram efeitos positivos sobre a diminuição dos sintomas climatéricos, bem como melhora nos domínios de qualidade de vida nestas mulheres, possibilitando efetivas propostas de intervenção profissional às especificidades deste público, com foco na promoção de saúde através de ações interdisciplinares

Avaliação dos parâmetros hematológicos e imunofenotípicos de pacientes com doenças linfoproliferativas crônicas no Rio Grande do Norte

Chronic lymphoproliferative disorders (DLPC) are lymphoid system diseases characterized by the abnormal proliferation of mature lymphocytes that affect B cells, T lymphocytes and NK cells. The aim of the study was to demonstrate the relevance of immunophenotyping by flow cytometry in patients with prolonged lymphocytosis and / or cytomorphological changes compatible with lymphoproliferative diseases. In this study 460 patients (244 men and 216 women) with DLPC were evaluated. Were analyzed by flow cytometry with a panel of monoclonal antibodies consisting of CD3, CD4, CD5, CD8, CD10, CD19, CD22, CD23, CD25, CD38, CD45, CD16/CD56, and HLADR heavy and light chains of immunoglobulins. It also examines information regarding age, gender of patients and laboratory data as leucocytes, cytomorphological analysis, platelet count and hemoglobin determination. The results showed 398 cases of chronic lymphoproliferative disorders and 62 of DLPC B cell lymphoproliferative diseases T. B showed the following distribution : 253 cases of chronic lymphocytic leukemia (CLL), 42 cases of multiple myeloma ( MM ), 37 cases of lymphoma non - Hodgkin lymphoma in leukemic phase (NHL) , 17 cases of pro- B lymphocytic leukemia ( B -PLL), 15 cases of mantle cell lymphoma (MCL ), 12 cases of plasma cell leukemia ( PCL), 9 cases of lymphoma Burkitt (Linf B), 8 cases of leukemia villous cells ( LCV), 3 cases of splenic lymphoma with villous cells (LECV), a case of follicular lymphoma (LF) and a Waldenströn macroglobulinemia ( MW). The diseases source NK / T were 23 cases of peripheral T cell lymphoma (LCTP), 14 cases of T prolymphocytic leukemia (T -PLL), 10 cases of leukemia T of large granular lymphocytes (LGL -T) 9 cases of leukemia cells of adult T (LCTA), 5 cases of Sezary syndrome (SS) and a case of large granular NK leukemia (LGL -NK) lymphocytes. In conclusion, the combined use of the monoclonal antibody panel careful cytomorphological analysis was shown to be essential in immune diagnosis and classification of chronic lymphoproliferative disorders. This study was approved by the IRB - HUOL under number 356 / 09

Avaliação de efeitos toxicológicos e comportamentais de ginseng panax em ratos

Panax ginseng CA Meyer (Araliaceae) is a herbaceous plant widely used in China, South Korea, Japan and other Asian countries for the treatment of various diseases micro circulatory, cerebrovascular, among others, representing one of the drugs used by older man. It has over 30 biologically active ginsenosides with different pharmacological and behavioral effects and inhibitory effect on the NMDA receptor. The amino acid glycine is a co-agonist of the NMDA receptor, activating this receptor. At the cellular level, ketamine is widely known to be NMDA receptor antagonist. The aim of this study was to evaluate the general activity in the open field, and anxiety in elevated plus maze, mice treated with P. ginseng compared with the action of ketamine and glycine, to better understand the action of this herbal medicine at the NMDA receptor. We used 66 adult male rats were divided into six groups: a positive control, treated for 30 days with water by gavage, who received glycine (500mg/kg; po) on days 7, 14, 21 and 28 of treatment, one hour before of behavioral assessment, a negative control was treated for 30 days with water by gavage received ketamine (5mg/kg, ip) on days 7, 14, 21 and 28 of treatment, one hour prior to behavioral evaluation, three experimental groups, receiving 100, 200 or 300 mg / kg P. ginseng by gavage for 30 days and one group treated solely with white water, and is also administered 1 ml of water by gavage one hour prior to behavioral evaluation. Animal behavior in these three groups was also examined on days 7, 14, 21 and 28 of treatment. On day 30 of treatment, the animals were anesthetized with thiopental (70mg/kg) for blood collection and after euthanasia, withdrawal of various organs. There were no changes in weight and body weight gain and weight reasons in organ / body weight. However the consumption of water and food values showed a significant increase. Serum levels of AST was increased in a dose-dependently in the animals treated with doses of P. ginseng, glycine and ketamine as compared to the blank group. Unlike creatinine levels proved to be decreased in all treated groups when compared with white. However, the level of urea in these groups was reduced and no changes were observed in the ALT parameter. Histopathological examination revealed no changes in cell morphology in different tissues. There were no behavioral changes in the elevated plus maze and few changes were observed in the open field, animals treated with P. ginseng, glycine and ketamine when compared to white. These data suggest that the doses of P. ginseng employed were unable to induce general toxicity in rats treated for 30 days and also shows that the general behavior of mice treated with P. ginseng was slightly different from that observed in animals treated with ketamine and glycine. Finally, the study on the elevated plus maze showed that the extract of P. ginseng showed no anxiolytic or anxiogenic action

Transplantes: re-inserção social e qualidade de vida dos transplantados cardíacos do Estado do RN

The experience of transplantation is a very serious situation from the clinical standpoint. Therefore, there must be some subjective and social breakdown in people who have been undergone such a procedure. Recent product of modernity, the transplanted is someone who owns his recover to the scientific advances of contemporary society and a deceased donor. This paper aims at examine the implications, from the changes in patterns of behavior and thought that occur after the experience of an extreme and critical situation, as the process of illness and its consequent transplant surgery. The symbolism of the heart suggests that some social impressions about the organ itself are also reflected in how the transplanted interprets the experience of this type of procedure. So investigating how the changes occurred throughout the process interfere in the re-insertion of these people to social life, after his recovery, is the purpose of this work. The concept of habitus coined by Pierre Bourdieu will be used to measure conceptually how this experience (clinical, modern and symbolic) fits in the contemporary discussion of sociology

Cola para quem tem fome: um ensaio sobre as potencialidades e limitações da sociologia da fome

This work aims to present a systematic study of sociology developed by Josué de Castro. It is a theoretical work that aims to evidence the potentialities and limitations of the hunger analysis theoretical models of contemporary sociology. It was used concepts of Social Institution (Berguer and Bourdieu), Habitus-precário and Ralé (Jessé Sousa) as weapons to comprehend better the hunger phenomenon on the sociology field, to consequently generate dialogs between Castros writings and the contemporary sociology. It demonstrates how hunger reproduces more by pre reflexive behavior patterns in a way that the moral rules become invisible and allow the phenomenon to continue in an invisible way

Folha de São Paulo: o diário oficial do grande irmão

This project wants to analyze the newspaper like a collective organic intellectual thing, and its action like a conservator integral journalism, it makes it looks like a politics block. In this case, the newspaper inserts itself in a process to support the dominated fundamental class. In the same time, it searches to disqualify politically, using the news and the opinion, the sprouting of against-hegemony even untimely and distant in the historical time. Facing this proposal we take as study object the FOLHA DE S. PAULO, nowadays the most representative agency of the great conservative press. Our theoretical reference takes as base the Gramsci organic intellectual formularizations, hegemony, position´s war, integral journalism and private device of hegemony. We allow ourselves, in a subsidiary way to the Gramsci basement, using the novel 1984 written by George Orwell, as a method to explicit, in a comparative way, the manipulation of the reality by the newspaper in its activity of collective organic intellectual. The ideology is the heuristic connection point to make convergence between reality and fiction. For the intended evidences we develop analysis of the daily covering about two great accidents occurred in 2007: The landslide of part of the workmanships of the tunnel of the Companhia do Metropolitano de São Paulo-Metrô (line yellow 4). And the flying disaster involving the airbus of Transportes Aéreos Meridionais-TAM, flight 3054, also in that state. In the first accident we find endorsement of the newspaper to the São Paulo´s government, in the person of the politician actor José Serra (PSDB), representative of the conservative forces and responsible for the workmanships of the Subway, to who it tried to distance politically of the fact. In the second event, the opposition to the politician actor Luis Inácio Luis Lula da Silva and his politics block, the PT, as a possibility against-hegemonic contested, being the mentioned actor appointed as responsible for the occurrence. However, the newspaper says that it is independent and direct, and this direct action comes from the environment. In this environment, the diversity of conceptions of world would guide the publishing work, making the FOLHA DE S. PAULO to take it as a reference for the intended objective, hiding the politics block militancy

Do controle de constitucionalidade dos atos jurisdicionais transitados em julgado

The following study aims to verify in which hypothesis res judicata, when it comes of an unconstitutional decision, shall not prevail over Constitution. It displayed the characteristics of formal and material constitutional systems. It debated the concepts of existence, validity and efficacy of juridical rules and acts. It dissertated about the idea of Constitution s superiority and about the birth of the judicial review of constitutionality. It focused some contemporary models of this judicial review and its historical evolution in Brazil, showing its effects towards the current Constitution. It sustained that the decision given by Supremo Tribunal Federal during abstract control of rules must bind even legislative bodies, preventing them to produce the same rules previously declared unconstitutional. It held up that all parts of the decision of Supremo Tribunal Federal oblige, even the juridical arguments employed, in both diffused and concentrated reviews. It showed that, despite these models of review live together in Brazil, our constitutional system preferred the concentrated one, considering one only court over the other constitutional organs. It discussed about res judicata with the purpose of clarifying its juridical nature, its objective and subjective limits and its regulation in collective demands. It explained that the material res judicata is an effect of a decision which cannot be reviewed, which makes the law s will free of discussion, binding the contendants and avoiding that other courts, judging future demands about the same object, may decide differently. It showed how the regulation of res judicata in collective demands, in respect oh their subjective limits, is useful to demonstrate that it is not the material law who must adapt itself to res judicata as traditionally thought, but res judicata, as a warranty of juridical certainty and security, who must be shaped from the debated rule. It presented to view the main doctrinal conceptions about res judicata s review in the hypothesis of unconstitutional judgement. It concluded that the decisions forged by unconstitutional rules or interpretations reputed not compatible to the Constitution by Supremo Tribunal Federal, in spite of it can make res judicata, may be reviewed beyond the term to file a recissory claim, since while the debated law is still valid, no matter if its decision was before or after the res judicata. At the end, it asserted that, when it is not legally authorized, the judicial review of res judicata is not admissible, after the term to file a recissory claim, under the argument that there was no direct violation to the constitutional principle or rule

A ação civil pública como meio de concretização do direito à saúde na Constituição de 1988

The work presented here is about aspects of the constitutional extension in which is the public civil action with the objective of verifying its aptitute in tutelaging subjective situations derived from fundamental rights, especially right to health assistance. Thus, it offers a clear analysis of the practical functioning of most aspects of the public civil action (lawsuit), with philosophical foundation and necessary doctrinaire to your comphehension. How it once was (history), how it could be (reform suggestion), how it is (current interpretation of the law) and how it should be (critic analysis of the microsystem of collective tutelaging of rights, its perspectives, as well as the efficacy of the public cilvil action about accomplishment of the right to health as supraindividual right). The objective is to analyse the main version of the theme (for instance: the impacts caused to the dissociation of the Procurations theory), so that it can be extracted the philosophy and the general theory, of the public civil action and collective tutelaging in general, pragmatically applicable to study purposes. With this theorical fountain, the reader will be in a more solid position, not only being able to understand the subtilities of the public civil action, but mainly being able to recognize its faults and present solid reform proposals and improvement. It is know that the Juridical Power (Procuration) does not allow any more inactivity about negating accession to health in its collective dimension (lato sensu: spread, collective stricto sensu and homogeneous individuals), being imputed to it novel usage that consolidates in the assumption of the role instrument set aside to be used by all with organized instancy of solution to collective conflicts in large sense. This happens, overall, because of the current justice politization, understood as juridical activism, connected to the struggle between the groups defending their interests and the acceptance of the constitution about solidifying the public politics of quality health

Repercussão geral e súmula vinculante: os efeitos no controle difuso

Brazil since its first republican constitution has adopted systems of laws control. The review activity was given to three state powers or functions state, Executive, Legislative and Judiciary. However, it appears that in the country along the constitutional history, has stood considerably the jurisdictional control of the most important control. Initially, back in 1891, Brazil adopted the jurisdictional control of diffuse from U.S, whose role in monitoring of standards is delivered to all organs of the judiciary, which may face a case, put on trial, ascertain whether or not the possibility of applying a law, removing its impact in case of unconstitutionality. In 1969, entered in the second legal model of judicial review, the concentrated control of constitutionality, whose inspiration comes from the positivist theory of Hans Kelsen, and was adopted by the Austrian Constitution of 1920. According to the abstract control the supervision of law is given to a Court or Constitutional Court, responsible for the analysis of the legal constitutionality independent of its application to a specific case. In Brazil the role of concentrated control was handed over exclusively to the Supreme Court, which serves as the Constitutional Court, which accumulates that function with other constitutionally provided jurisdiction. Throughout this period, from 1891 until today, Brazil has maintained a dual system of judicial control of legal constitutionality, where they coexist and harmonize the diffuse control exercised by any organ of the Judiciary, and concentrated control of competence the Supreme Court. However, one must recognize that with the advent of the Federal Constitution of 1988, the concentrated control has emerged on the national stage due to two important factors: the expansion of the legal capacity to sue and the inclusion of other ways control, besides the already known Direct Claim of Unconstitutionality. This concentrated control and projection of the Supreme Court s attempt to become a true constitutional court, led to a relative weakening of diffuse control even when performed by the Brazilian Constitutional Court. In order to become a true constitutional court, all decisions handed down by the Supreme in the exercise of constitutional jurisdiction should have the same weight and the same measure, or at least bring improvement to similar effects, once is the responsible for the final word when it comes to constitutional interpretation. Thus, the writs of certiorari and stare decisis were responsible for profound changes in the diffuse control, allowing the Supreme Court can strengthen its decisions even in the diffuse control. These two institutions have substantially changed the legal status of diffuse control, allowing an extension of the effects of decisions handed down by the Supreme Court, so that you can no longer be said that the effects of this control to restrict the disputing parties in the process

Defensoria pública e sua legitimidade à tutela jurídica dos direitos humanos

The realization of human rights is a prerequisite to the development of peoples, this requires legal mechanisms and techniques to its consistent and effective promotion, protection and fulfillment. So, agree that there is an institution or public agency created for the purpose of protecting those who suffer most in the face of human rights violations: the needy. In Brazil, among other institutions and public agencies, the responsibility of the Public Defender to promote the protection of human rights. The constitutional system recognizes the institution in its essence the role of the state court, whose duty is to provide guidance and legal defense of the needy. The legal system as a whole sufraga the relevance of the Ombudsman as a mainspring of human rights. In the prison system, with the ultimate regulatory changes, such as Law 12.313 of 2010 which introduced changes to the Law 7.210 of 1984, the institution must ensure the correct and humane enforcement of sentences and the security measures pertaining to the needy. With the Complementary Law 132 of 2009, to systematize other duties of the Public Defender, highlighting their contribution to the movement of access to justice. Within the OAS, to adopt Resolution 2656, 2011, characterizing, with ruler and compass, the relevance of the Ombudsman access to justice and protection of human rights. In this step, the present study concerns the role of Defender in the legal protection of human rights, through monographic and deductive methods, as there remains a technical and theoretical connection between these two points themed legal phenomenon, since the rights humans, especially after the second half of the twentieth century, form the basis of the legal system of the major Western nations in the world. This led, therefore, the emergence of technical and legal institutions aimed at realizing human rights. This applies to the Defender. Access to justice and public service provision of legal assistance are human rights, therefore, essential to humans and necessary for social inclusion. Countries such as Brazil, marked by social inequality, depend on the structuring of institutions like the Defender, designed to promote citizenship to the Brazilian people

Intervenção judicial nas sociedades limitadas em face da liberdade de iniciativa

The judicial intervention in limited liability company goes through several issues of legislative and hermeneutics origin, based considerably on the small importance given to freedom of economic initiative by the participants in the process of formation and application of the law. In addition, Brazilian law, due to incompleteness, inconsistency or lack of valid grounds, put the judge in a procedural delicate situation. Being forced to judge, the judiciary faces severe uncomfortable interpretive situations, of which derive solutions of dubious constitutionality and affecting, significantly, the dynamics of business activity. In this context, and considering the limited liability company as an expression of free enterprise, corresponding to a lawful association of people in order to undertake economically, in exercise of his freedom of contracting and professional action, intended to be offered safe parameters of constitutionality for judicial intervention in limited liability company in the hypothesis of (i) transfer of corporate shares, (ii) attachment of corporate shares, (iii) dismissal of directors, (iv) appointment of judicial stakeholders, (v) exclusion of shareholders and (vi ) trespass. The hypothetical-deductive approach was adopted, building hypotheses to overcome the gaps and unconstitutionality of the law and subjecting them to tests, reviews, and comparisons with hypothetical facts and case law in order to determine the constitutional validity of the proposed solutions. The procedure aimed to reconcile the historical, comparative, dialectical and scientific methods. The roots of temporal institutes were researched as well as current solutions provided by national and compared law. From problematizations point, addressed by the constitutional interpretation of the law and jurisprudence, responses that bring out the unconstitutionality of certain conceptions were headed

Democracia brasileira: fortalecimento da participação popular

A democracia tem representado ao longo da História o mais perfeito mecanismo político de convivência social, encontrando na soberania popular seu fundamento e legitimidade. De berço grego, instituiu-se sob princípios que radicavam o poder político no povo, exercido diretamente na ágora ateniense. O iluminismo dos séculos XVII e XVIII reacendeu o ideal democrático, encontrando no positivismo sua base teórica. O poder passou a ser exercido por via de representantes eleitos periodicamente. O locus da atividade política era o parlamento, ambiente fechado e refratário à participação popular, cingida, à época, ao voto do cidadão nos períodos eleitorais. O distanciamento entre governantes e governados gerou déficit de legitimidade no modelo liberal clássico, levando o constitucionalismo do século XX a abandonar o rigor formal positivista, para adotar uma nova hermenêutica, de base axiológica e centrada na participação direta do povo nas instâncias do poder. A Constituição Federal de 1988 compendiou a democracia participativa em seu texto, declarando no parágrafo único, de seu artigo 1º, que todo o poder emana do povo. Consagrou como base da soberania popular o sufrágio universal, o voto direto, secreto e de igual valor, além do plebiscito, do referendo e da iniciativa popular de leis. Garantiu ainda a ação popular como ferramenta de cidadania. A participação popular foi restringida com o advento da Lei nº 9.907/98, que impôs bloqueios processuais para seu exercício, gerando déficit de legitimidade no sistema representativo brasileiro. O propósito desse trabalho é demonstrar a necessidade de se estabelecer um novo espaço público na ordem constitucional do Brasil, de textura aberta e dialógica e de perspectiva emancipatória, que customize a participação do povo nas instâncias do poder, a partir da desburocratização dos instrumentos de soberania popular já existentes e da adoção de outros institutos democráticos semidireto, notadamente a iniciativa popular de emenda à Constituição, a revogação de mandato eletivo e o veto popular

Um estudo sobre as origens da Lógica Matemáitca

The present study has as objective to explaining about the origins of the mathematical logic. This has its beginning attributed to the autodidactic English mathematician George Boole (1815-1864), especially because his books The Mathematical Analysis of Logic (1847) and An Investigation of the Laws of Thought (1854) are recognized as the inaugural works of the referred branch. However, surprisingly, in the same time another mathematician called Augutus of Morgan (1806-1871) it also published a book, entitled Formal Logic (1847), in defense of the mathematic logic. Even so, times later on this same century, another work named Elements of Logic (1875) it appeared evidencing the Aristotelian logic with Richard Whately (1787-1863), considered the better Aristotelian logical of that time. This way, our research, permeated by the history of the mathematics, it intends to study the logic produced by these submerged personages in the golden age of the mathematics (19th century) to we compare the valid systems in referred period and we clarify the origins of the mathematical logic. For that we looked for to delineate the panorama historical wrapper of this study. We described, shortly, biographical considerations about these three representatives of the logic of the 19th century formed an alliance with the exhibition of their point of view as for the logic to the light of the works mentioned above. In this sense, we aspirated to present considerations about what effective Aristotelian´s logic existed in the period of Boole and De Morgan comparing it with the new emerging logic (the mathematical logic). Besides of this, before the textual analysis of the works mentioned above, we still looked for to confront the systems of Boole and De Morgan for we arrive to the reason because the Boole´s system was considered better and more efficient. Separate of this preponderance we longed to study the flaws verified in the logical system of Boole front to their contemporaries' production, verifying, for example, if they repeated or not. We concluded that the origins of the mathematical logic is in the works of logic of George Boole, because, in them, has the presentation of a new logic, matematizada for the laws of the thought similar to the one of the arithmetic, while De Morgan, in your work, expand the Aristotelian logic, but it was still arrested to her

Professores em contexto formativo: um estudo do processo de mudanças de concepções sobre o ensino da matemática

El objetivo en esta tesis consistió en estudiar el proceso de los cambios de los conceptos de profesores de la educación infantil y de los años iníciales de la educación básica referente a la enseñanza de la matemática. La investigación se desenvolvió en la escuela Presidente Kennedy, en la ciudad de Natal, en Rio Grande do Norte, teniendo como participante 05 (cinco) profesores del curso normal superior a través de la educación superior del instituto relacionado. El trabajo asocia el programa a él Programa de Pós-Graduação em Educação da Universidade Federal do Rio Grande do Norte, en la base de pesquisa Formação e Profissionalização Docente coordinada de los doctores Betânia Leite Ramalho e Isauro Beltran Núñez. El referencial teórico-metodológico en quien si apoya el trabajo se inserta en la señal conceptual usada por Giordan y de Vecchi (1996), de Carrillo y Contreras (1994), Ramalho; Núñez y Gauthier (2003), Ponte (1998), Guimarães (1988), Ernest (1989). En esta investigación, los conceptos de los profesores habían sido estudiados en el contexto educativo de la formación del nivel superior, usándola reflexiva crítico práctico como estrategia formativa. Estos conceptos se entienden como estructuras subyacentes al pensamiento del profesor. Dado la naturaleza del objeto del estudio, la información, para las intenciones de esta investigación, habían sido cosechados a través de los instrumentos siguientes: cuestionario, plan de la lección, entrevista diaria y del campo. El cuestionario fue constituido de preguntas abiertas y de las entrevistas de la mitad-structuralized. La organización de los datos permitió a La inferencia de los conceptos, usando la técnica de la triangulación de datos. La investigación divulgó que los conceptos de los profesores, a través del proceso formativo, se habían desarrollado de una plataforma para otra, yéndose puesto que los modelos didácticos tradicionales para otros modelos dirigidos a una tendencia didáctica de espontaneísta/investigativa. La reflexión crítica era considerada como elemento catalítico de los cambios de los conceptos de los profesores en la educación de las matemáticas, sin embargo déjenos verifican que estos cambios son difíciles de ocurrir para la naturaleza compleja de estos conceptos. Como facilitadores de los factores de estos cambios, encontramos y el investigativo el trabajo, la dinámica y la naturaleza de las actividades se convirtió en el colaborativo de proceso formativo, entre otros. Como obstáculos a los cambios, identificamos el contexto del trabajo de los profesores, de la cultura de los individualistas prácticos de sus profesores de los colegas, del concepto linear, estático y de los mecánicos de los procesos para enseñar, el conocimiento profesional construído durante la formación inicial, alineación con los modelos didácticos de sus viejos profesores, entre otros

Pedagogia etnomatemática : ações e reflexões em matemática do Ensino Fundamental com um grupo sócio cultural específico

mongst the trends in Mathematics Education, which have as their object a more significant and criticallearning, is the Ethnomathematics. This field of knowledge, still very recent amongst us, besides analyzing an externalist history of the sciences in a search for a relationship between the development of the scientific disciplines and the socio-cultural context, goes beyond this externalism, for it also approaches the intimate relationships betwe_n cognition and culture. In fact, the Ethnomathematics proposes an alternative epistemological approach associated with a wider historiography. It struggles to understand the reality and come to the pedagogical action by means of a cognitive approach with strong cultural basis. But the difficulty of inserting the Ethnomathematics into the educational context is met by resistance from some mathematics educators who seem indifferent to the influence of the culture on the understanding of the mathematics ideas. It was with such concerns in mind that I started this paper that had as object to develop a curricular reorientation pedagogical proposal in mathematics education, at the levei of the 5th grade of the Ensino Fundamental (Elementary School), built from the mathematical knowledge of a vegetable farmers community, 30 km away from the center of Natal/RN, but in accordance with the teaching dimensions of mathematics of the 1 st and 2nd cycles proposed by the Parâmetros Curriculares Nacionais - PCN: Numbers and Operations, Space and Form, Units and Measures, and Information Treatment. To achieve that, I developed pedagogical activities from the mathematical concepts of the vegetable farmers of that community, explained in my dissertation research in the period 2000 through 2002. The pedagogical process was developed from August through Oecember 2007 with 24 students of the 5th Grade of the Ensino Fundamental (Elementary School) of the school of that community. The qualitative analysis of the data was conducted taking into account three categories of students: one made up of students that helped their parents in the work with vegetables. Another one by students whose parents and relatives worked with vegetables, though they did not participate directly of this working process and one third category of students that never worked with vegetables, not to mention their parents, but lived adjacent to that community. From the analyses and results of the data gathered by these three distinct categories of students, I concluded that those students that assisted their parents with the daily work with vegetables solved the problem-situations with understanding, and, sometimes, with enriching contributions to the proposed problems. The other categories of students, in spite of the various field researches to the gardens of that community, before and during the pedagogical activities, did not show the same results as those students/vegetable farmers, but showed interest and motivation in ali activities of the pedagogical process in that period
