Ambiente pesqueiro e saúde: representações sociais sobre saúde e doença de pescadores e marisqueiras nos distritos de Diogo Lopes, Barreiras e Sertãozinho Macau RN

According to Brazil s Ministry of Fisheries and Aquaculture, artisanal fishermen are responsible for a significant fish production at national level, highlighting the importance of this activity. In Rio Grande do Norte State, Brazil, fishing has become an important part of economic and social processes. In this context, there are many inland fishing communities such as Barreiras, Diogo Lopes and Sertãozinho, which are part of Ponta do Tubarão State Reserve of Sustainable Development (RDSEPT), located in Macau and Guamaré, Rio Grande do Norte coastline cities. Fishermen and women, the last ones known as marisqueiras who work alongside the menfolk at sea, especially in the shellfish harvest, have been developing narrow relationships with nature, mainly with the sea, from where they extract their families subsistence. However, those communities have been facing several issues related to living conditions, health and diseases. Social representations have been analyzed in the speeches of fishermen/women who were registered active members in a fishermen association named Associação Colônia de Pescadores Z-41, regarding the period from 2008 to 2011. The analysis involved socio-economic profiles verification, identification and analysis of the group s main representative diseases and representations related to health and illness. This study searched for elements in order to provide the comprehension of the relationships among people s social representations and the fishing environment in which they live.. This qualiquantitative study was performed using recordings and transcriptions of structured and open-question interviews. The Collective Subject Speech tecnique proposed by Lefevre & Lefevre (2002) was applied to perform the interviews analysis using QualiQuantiSoft® software. The results showed that health and illness phenomena as well as social representations related to them in the fishing environment are not only abstract states but also physical ones, which interfere in all life extensions, establishing a set of relevant information that indicates that those people realize their own socio-cultural, economic, environmental and political context

É como se tivesse a roça e faltasse a enxada: formação em serviço de professores de História no ensino sergipano

This thesis has the aim to comprehend the development of the superior graduation in life service and daily scholar of the history teachers in-land of Sergipe. The History Course graduation was realized through the second part of (Projeto de Qualificação Docente-PQD), the so-called, Teaching Qualification Project of the Federal University of Sergipe, first settled in 1998. Eight teachers were chosen for this research with more than (15) fifteen years of teaching in the Fundamental and Medium levels at public schools of our state (Sergipe). This empiric research priviledged oral testimony from them, which (ones) reveled about the memory tragetory of life. Since childhood until the History Course graduation, besides the evidence as Principal of schools as well as the following classes. All of them were interviewed from in-land and they are from very poor families with lack of social economical conditions. Those evidencies point out economic limitations in their different towns, that contributed to the continuous obstacle in the following studies, moreover in the common market. Therefore they still teach in order to believe in who´s at the botton of this business. Their testimony about this history graduation through PQD , gave them new Professional horizons, modifying their pedagogic practice, choosing what is worth into the social space beyond life expectancy. Through the analyses from all the documents and evidence in loco, it was evident that this graduation is not sufficient to change all the acting of teaching. Consequently, the lack of scholar situation still happens because this qualification doesn´t consider the knowledge of the teachers into their contexts. This research could also observe that besides the changing purposes in the suggested common-job by the globalization, the public politics education, is still underdeveloped in-land of Sergipe. According to the educational laws which obliges all tearches should be graduated, it could be observed that nothing changed into their acting. The old curricula don´t give them new possibility in their acting. At last their salaries, poor conditions in their common-job as well as the difficult ways to get to their pos graduation course still contributes to the underdeveloped acting before they´d graduated from the period before of their graduation

Avaliação das barragens subterrâneas no regime de um curso d água na região do semi-árido do RN

The Serido is a region of northeastern Brazil highlighted by its problems related to water scarcity because of its semi-arid region, large rates of evaporation and rainfall irregular and scarce. Thus, the underground dams, become a strategically important resource with a simple and inexpensive technique for storage of water. They act in a positive way in the development of inland cities that suffer from drought, because in addition to exercise a great improvement in the social role of these families, can enjoy the type of soil (silt) and provides water for both irrigation and for human consumption throughout the year. Is therefore essential to its monitoring and studies to assess its effectiveness in accordance with its purposes, along with their wells Amazons, as can occur in conditions of physical degradation, chemical and microbiological appropriate, according to the Ordinance No 518/04 Ministry of Health, however, the proposed work aims to analyze the underground dams in the municipality of Sierra Negra North-RN (semi-arid region) as to their uses and their influences on the quality and quantity of water in periods of drought and rain. Analyzing monthly these parameters: determination of pH, conductivity, calcium, magnesium, sodium, potassium, chloride, sulfate, RAS (sodium adsorption ratio), turbidity, total iron, nitrite, nitrate, total dissolved solids (STD), bicarbonate (HCO3), fecal coliform and pesticides compared to the standards allowed by the Ordinance in force for quality for human consumption. While at the risk of salinity and sodicity on the model proposed by the United Salinity Laboratory (USSL). Although efficient, it was found that results varied annually on water quality which may influence their specific uses, whether or irrigation water supply in the city

Educação científica no contexto pós-ontológico: por uma concepção plural de conhecimento e educação

The development of this work arises from the research of sociological and philosophical characters contemplating also other approaches which aims to answer the followingquestions: what is the responsibility of science teaching for the image one has about science? ; which scientific education should be designed for nowadays? . After considering the assumptions brought along by rationalism and the criticisms to the illuminist model proposed by sociology and philosophy of science, as well by the biology of the knowing process, going through discussions concerning post-modernity issues, one is given to understand that the image of science has become the central point of discussion in the last hundred years, including what concerns the area of science teaching, and that practically none of those discussions really reached natural science classes indeed. We adopt the term postontological to characterize the recent proposals on philosophy and sociology, because we evaluate that this term allows a better identification of the scientific realism crisis, which supports the existence of an ontological domain which science, and only science, is able to understand. One notices that the general public is not aware of those discussions, mainly if they are science teachers and students. So we believe that discussing the logic in which science is structured, the new understandings concerning the scientific undertaking, especially those of an externalist character, and the relationship between science and society, all of this contributes to build up a science teaching which contemplates a reflective contribution, besides allowing the inclusion of the study of other epistemologies in the educational practice. We argue that a revisionist posture seems to be the most appropriate for the contemporary scientific education, contemplating, besides the teaching of the usual science contents, discussions on the issues involving that knowledge, as well as respecting epistemologies alternative to the modern Western scientific one, in order one can work on the perception of local knowledge generated from other epistemological bases. We describe here practical activities we did involving teachers (short-term courses) and high-school students in an inland school in the Rio Grande do Norte state, in Brazil, as a way to demonstrate the possibility of interventions which can take those conceptions, discussions and changes to the classroom

Conciliação entre modelos de mecanismos avançados de oxidação eletroquímica

Many pollutants dumped in waterways, such as dyes and pesticides, have become so ubiquitous that they represent a serious threat to human health. The electrochemical oxidation is presented as an alternative clean, efficient and economic degradation of wastewater containing organic compounds and a number of advantages of this technique is to just not make use of chemical reagents, since only electrical energy is consumed during the removal of pollutants organic. However, despite being a promising alternative, still needs some tweaking in order to obtain better efficiency in the elimination of persistent pollutants. Thus, this study sought a relationship between a recently discovered phenomenon that reflects the participation of dissolved oxygen in solution in the electrochemical oxidation process, as an anomaly, present a kinetic model that shows instantaneous current efficiency (ICE) above 100% limited by theory, manifested for some experiments with phenolic compounds with H2SO4 or HClO4 as supporting electrolyte with electrodes under anodic oxidation on boron doped diamond (BDD). Therefore it was necessary to reproduce the data ICE exposes the fault model, and thus the 2-naphthol was used as phenolic compound to be oxidised at concentrations of 9, 12 and 15 mmol L-1, and H2SO4 and HClO4 to 1 mol L-1 as a supporting electrolyte under a current density of 30 mA cm-2 in an electrochemical reactor for continuous flow disk configuration, and equipped with anodes DDB at room temperature (25 oC). Experiments were performed using N2 like as purge gas for eliminate oxygen dissolved in solution so that its influence in the system was studied. After exposure of the anomaly of the ICE model and investigation of its relationship with dissolved O2, the data could be treated, making it possible for confirmation. But not only that, the data obtained from eletranálise and spectroscopic analysis suggest the involvement of other strongly oxidizing species (O3 (ozone) and O radicals and O2 -), since the dissolved O2 can be consumed during the formation of new strong oxidizing species, not considered until now, something that needs to be investigated by more accurate methods that we may know a little more of this system. Currently the performance of the electrocatalytic process is established by a complex interaction between different parameters that can be optimized, so it is necessary to the implementation of theoretical models, which are the conceptual lens with which researchers see
