Leptospirosis is a worldwide zoonosis of considerable medical and economical importance that affects humans in both urban and rural contexts, as well as domestic animals and wild fauna. Leptospira interrogans is the causative agent and is transmitted to humans by indirect contact with contaminated soil or water. The clinical syndromes include sub clinical infection, self-limited anicteric febrile illness, and severe and potentially fatal illness, known as Weil´s syndrome. In developed countries, leptospirosis is related to occupational or recreational activities while in developing countries, outbreaks occur during floods. In those regions, traditional strategies to prevent the transmission are difficulties to be implemented because of costs and lack of community acceptance. In addition, no efficient vaccine is available for human use. Several studies have suggested that chemoprophylaxis with doxycycline pre and post-exposure may be effective to prevent leptospirosis. Leptospirosis has been reported in rural areas of the State of Rio Grande do Norte, Brazil since 1985 in rice farmers who present the anicteric illness. The disease cause great social and economics impact. The study was conducted in São Miguel where an epidemic of leptospirosis in rice farmers was reported. The main objective was to determine the efficacy of doxycycline in preventing Leptospira exposure. A taxa de soroprevalência de leptospirose na população estudada antes e após a colheita foi de 14,2% (n=22) e de 16.6% (n=27) respectivamente. Anti-Leptospira serology was determined for 61 subjects in two instances, pre and post-exposure to potential contaminated water. There was an increased risk of 29.0 per cent in acquiring infection for individuals that did not use doxycycline. In addition, an increased risk of 30.0 % observed in farmers who did not use protection when exposed to Leptospira. The adhesion to preventive chemoprophylaxis was 55.7%. Therefore doxycycline, under specific circunstances appears to be an effective alternative to protect against leptosprirosis infection. A large sample composed of individuals to adhere to preventive therapy is needed to define time, dosage and length of use of doxycycline in this area

This work has the main purpose of conducting a survey of educational products present in dissertations and doctoral theses focused on the use of history in mathematics teaching and Didactics of mathematics with a French foundation produced in graduate programs in the strict sense of the Brazil between 1990 and 2010, the areas of Education, Mathematics Education, school of Natural Sciences and Mathematics and related areas, according to the research proposal of Mendes (2010). Our interest was to select the products that present concrete proposals for educational activities that can be used in the classroom of Basic Education and Training of Teachers of Mathematics. The research was implemented through a bibliographic study documents the Bank of dissertations and theses from CAPES, libraries and archives of some Postgraduate programs in the country who focus their studies on the subject object of this research, besides the Brazilian Digital Library Theses and Dissertations (BDBTD). From this survey we selected works that present educational products materialized in blocks of activities based on the use of teaching history of mathematics to the classroom as well as the sequence of activities based on the Teaching of Mathematics. In possession of material, produce a CD-ROM containing the selected activities, in order to help support the work of teachers regarding the use of these activities, as a supplementary material to textbooks in their math classes

Intrafamily sexual violence against children and adolescents is a highly complex and serious issue in terms of the damage caused to this population. However, despite the relevance of this discussion, the matter only began to be addressed in the second half of the twentieth century, with its inclusion in academic research from the perspective of damage caused to the victims. Debate on intrafamily sexual violence against children and adolescents has intensified in recent decades, particularly with the enactment of the Statute on Children and Adolescents (Federal Law 8069/90), which recognizes children and adolescents as rights holders. Open discussion on the issue meant several fields of knowledge began to study the topic. Particularly prominent among these areas is the field of Psychology, promoting theoretical discussions and practical interventions focusing on this type of violence. Given the theoretical and methodological diversity of psychological science and the many possibilities for the production of knowledge, this study aims to map and debate research conducted in the field that discusses intrafamily sexual violence against children and adolescents in Brazil. To that end, articles published in Psychology journals were analyzed. In order to achieve this objective, a search was conducted of Scielo Brasil using descriptors on the subject, chosen from a list reported by Faleiros (2000). The time frame studied was between 1990 and 2013, therefore included the date of the enactment of the Statute of Children and Adolescents. Qualitative analysis was selected as a data analysis technique around two main themes. The first involved analyzing the concept of intrafamily sexual violence based on its components. The second analytical theme addressed the theoretical and methodological strategies used by the authors. The aim was to identify and discuss the approaches chosen to achieve the proposed objectives as well as the justifications provided by the authors for their research. Analyses of these themes were based on theoretical discussions on intrafamily sexual violence against children and adolescents. Difficulties were identified in conceptualizing intrafamily sexual violence so as to include all its elements and differentiate it from sexual exploitation. The studies assessed showed substantial diversity in both the theoretical and methodological approaches used, contributing to understanding the phenomenon. It is expected that this study will contribute to reflection on intrafamily sexual violence against children and adolescents, promoting new studies and/or practical interventions

The present research study the work professional of the Social worker in the National Institute of Social Security of Rio Grande do Norte s State, especially about the working terms, the demands and working process of Social worker in consequence of the limits established with disorganization of his institutional space derived of the Counter-Reforms of the State and of Social Security. In decade of 1990 there was in Brazil adhesion to the neoliberal politics what configured a new organization of work and a new performance of the State. Inside this context, it was accomplished the Counter-Reforms with emphasis in the privatizations, reform of the Social Security and of the device of the Brazilian State, among other actions. Particularly, in Social Service reforms brought profound consequences for the Social workers of INSS, among it: reduction of professionals and in his institutional space. This study situates the Social Worker of Social Security in front of the contemporary modifications in the world of work as well as in front of the consequences come upon of the Counter-Reforms implemented and executed by the neoliberal governments in the country of way the of frame and to enter to the globalized world and the new order of the capital. From the qualitative research based in the critical and dialectic theoreticianmethodological perspective that study the phenomena from your relations, mediations and contradictions, was possible unveil the limits and the possibilities of the professional work of the Social worker in INSS placed the Counter-Reforms of Social Security. Synthetically, the results of this investigation indicate that, there is an worsening in the inconsistency of the work with relation to social worker's functional situation and his working terms in the institution

Student’s mistakes as viewed in a didactic and pedagogical perspective are a phenomenon inevitably observed in any context in which formal teaching-andlearning processes are taking place. Researchers have shown that such mistakes are viewed most of the times as undesirable and often as a consequence of lack of attention or poor commitment on the part of the student and rarely considered didactically useful. The object of our reflections in this work is exactly those mistakes, which are born in the entrails of the teaching-and-learning processes. It is our understanding that a mistake constitutes a tool which mediates knowledge and may therefore become a strong ally of the instructor’s actions in her/his teaching tasks and thus should be taken into the teacher’s best consideration. Understanding a mistake as so, we postulate that the teacher must face it as a possibility to be exploited rather than as a negative occurrence. Such an attitude on the part of the teacher would undoubtedly render profitable didactic situations. To deepen the understanding of our aim, we took a case study on the perception of senior college students in the program of Mathematics at UFRN in the year 2009, 2nd term. The reason of this choice is the fact that Mathematics is the field presenting traditionally the poorest records in terms of school grades. In this work we put forth data associated to ENEM1 , to the UFRN Vestibular2 and the undergraduate courses on Mathematics. The theoretical matrixes supporting our reflections in this thesis follow the ideas proposed by Castorina (1988); Davis e Espósito (1990); Aquino (1997); Luckesi (2006); Cury (1994; 2008); Pinto (2000); Torre (2007). To carry out the study, we applied a semi-structured questionnaire containing 14 questions, out of which 10 were open questions. The questions were methodologically based on the Thematic Analysis – One of the techniques for Content Analysis schemed by Bardin (1977) – and it was also used the computer program Modalisa 6.0 (A software designed by faculties the University of Paris VIII). The results indicate that most of the teachers training instructors in their pedagogical practice view the mistakes made by their students only as a guide for grading and, in this procedure, the student is frequently labeled as guilty. Conclusive analyses, therefore, signal to the necessity of orienting the teachers training instructors in the sense of building a new theoretical contemplation of the students’ mistakes and their pedagogical potentialities and so making those professionals perceive the importance of such mistakes, since they reveal gaps in the process of learning and provide valuable avenues for the teaching procedures.

This research aims to make a reflective analysis about the academic production originated in the stricto sensu post graduation programs in the country, produced in the period of 1990 to 2010, in the field of History of Mathematics, especifically on works about the History of Mathematics in Mathematics education and that present pedagogical proposals that make use of the History of Mathematics in order to teach Mathematics. Defending the thesis that the researches on mathematics education with goals turned to the use of didactic proposals related to the history of mathematic that take in consideration the coherency between epistemological aspects inherent to mathematics history and anthological elements materialized on the conceptions of mathematics and mathematics history and of apprenticeship (implicitly or explicitly exposed) may originate significant contribution to the field of history of mathematics on education. Among these, nine were Master’s Degree dissertations and five PHD’s theses. The reflective analysis was accomplished from two matrixes; one from theoretical nature and the other, ontologic nature, elaborated from the pretexts of Sanches Gamboa, about the epistemological analysis from academic production in the field of Mathematics Education and the following theoretical perspectives in the field of History of Mathematics Education, that are: linear evolutionary theory, structural construtivist operative, evolutionary discontinuous, historical and socialcultural investigation and the use of activities estimulating the usage of verbal and nonverbal expressions. These perspectives were based on the works of Miguel and Miorim, Mendes and Radford. As results, we have detected some established dissonances between the categories related to theoretical and ontologic levels and the pedagogical proposal presented in these researches. On the other hand, we have discovered works that are able to establish consonances between the theoretical and ontological elements and the presented pedagogical proposal. These works carry significative contributions to the field of History of Mathematics applied to Mathematics pedagogical practice, inclusively presenting significative theoretical elements to the production of knowledge recognized as scientific in the Mathematics field
