Estuda a relação entre o Programa de Interiorização do Curso de Formação de Professores para Pré-Escolar e 1ª a 4ª do Ensino Fundamental, da Universidade do Estado do Pará e as políticas oficiais de formação de professores(as) desencadeadas no Brasil no período de 1999 a 2004. O objetivo é analisar a política de interiorização desenvolvida pela Universidade do Estado do Pará (UEPA) nesse Programa e sua relação com as políticas oficiais de formação de professores(as) implementadas no Brasil, a partir da década de 1990. A hipótese inicial era de que a política de formação de professores(as) adotada pela UEPA, no referido Programa, favoreceu a ampliação do mercado formativo no estado do Pará e, com isso, ocasionou uma corrida de professores(as) e de prefeituras àquela instituição, para a realização de processos de qualificação em nível superior. Para constatar essa hipótese, fez-se uma investigação do problema, orientada por pressupostos da abordagem qualitativa. Para coleta dos dados, realizou-se uma pesquisa bibliográfica, tendo como fonte: literatura especializada e documental; na pesquisa de campo, utilizou-se de entrevistas com os(as) alunos(as), professores(as), gestores(as) e os(as) secretários(as) de educação dos municípios atendidos pelo programa. Para análise dos dados, utilizou-se o critério de categorização temática para perceber e identificar as informações manifestadas nos enunciados dos conteúdos. A análise dos dados confirmou a relação do Programa de Interiorização do CFP com as políticas oficiais de formação de professores(as), especialmente, quando o Estado se desresponsabilizou dessa formação em nível superior, ao tornar a educação uma atividade não-exclusiva do Estado, o que favoreceu a ampliação do mercado formativo no Pará. A UEPA, sem apoio do Governo Estadual, oferta o Programa de Interiorização do CFP por meio de contrato de prestação de serviços educacionais.

This study quantifies fifth year medical students' knowledge after their participation in a basic clinical integration activity of psychiatry and pharmacology and investigates their opinions on the importance of the activity. A quali-quantitative study was performed using pre- and post-test assessment (multiple choice) and linguistic content analysis using the Discourse of the Collective Subject (DCS) technique. A significant increase in the percentage of correct answers in the post-test assessment was found compared to pre-test (p <0.001). The central ideas obtained from the DCS content analysis were: very relevant activity; expansion of the activity to other internships; difficulty in basic disciplines; application of cognitive assessment; and teacher's active participation in discussions. These results suggest that integration between pharmacology and the practical intern activities in psychiatry allowed pharmacological concepts to be broadened, rendering the learning meaningful. Although students identified the need for better organization of the activity, its the level of acceptance was verbalised through the suggestion that it could be extended to the other fifth year internships.

Environmental monitoring of aquatic systems is an important tool to support policy makers and environmental managers' decisions. Long-term, continuous collection of environmental data is fundamental to the understanding of an aquatic system. This paper aims to present the integrated system for environmental monitoring (SIMA), a long-term temporal series system with a web-based archive for limnological and meteorological data. The following environmental parameters are measured by SIMA: chlorophyll-a (µgL-1), water surface temperature (ºC), water column temperature by a thermistor string (ºC), turbidity (NTU), pH, dissolved oxygen concentration (mg L-1), electric conductivity (µS cm-1), wind speed (ms-1) and direction (º), relative humidity (%), shortwave radiation (Wm-2) and barometric pressure (hPa). The data were collected in a preprogrammed time interval (1 hour) and were transmitted by satellite in quasi-real time for any user within 2500 km of the acquisition point. So far, 11 hydroelectric reservoirs are being monitored with the SIMA buoy. Basic statistics (mean and standard deviation) and an example of the temporal series of some parameters were displayed at a database with web access. However, sensor and satellite problems occurred due to the high data acquisition frequency. Sensors problems occurred due to the environmental characteristics of each aquatic system. Water quality sensors rapidly degrade in acidic waters, rendering the collected data invalid. Data is also rendered invalid when sensors become infested with periphyton. Problems occur with the satellites' reception of system data when satellites pass over the buoy antenna. However, the data transfer at some inland locations was not completed due to the satellite constellation position. Nevertheless, the integrated system of water quality and meteorological parameters is an important tool in understanding the aquatic system dynamic. It can also be used to create hydrodynamics models of the aquatic system to allow for the study of meteorological implications to the water body.

Background: The use of all by-products of bovine slaughter is of high economic importance for the industries of products of animal origin. Among these products, fat has an important role, once fat rendering may generate several different products, such as protein material that may be used in the manufacture of meat products. However, in spite of the importance that the use of all by-products has for the economic balance of the industry, there are no reports on their use in Brazil, or studies that supply data on microbiological and physical-chemical local standards for this protein. Thus, the objective of this study was to evaluate microbiological and physical-chemical characteristics of protein material obtained from fat rendering, as well as to provide support for companies to use fat rendering to generate protein material, adding value to industrialized meat products.Materials, Methods & Results: The experimental production of edible protein obtained of fat rendering was conducted in slaughterhouse with supervision of the Brazilian Ministry of Agriculture, Livestock and Food Supply. Protein material was obtained in a continuous, humid heat system at high temperatures. Fat scraps containing protein were ground and cooked at high temperature (85 degrees C), and placed in a three phase decanter centrifuge. After centrifugation, protein material was ground again and packed. Samples were collected from 15 batches of protein material, and the following microbiological analyses were carried out: counts of aerobic mesophilic and psychrotrophic microorganisms, coliforms at 35 degrees C, Escherichia coli, sulfite-reducing Clostridium, and Staphylococcus aureus, besides presence or absence of Salmonella and Listeria monocytogens. The following physical-chemical analyses were also carried out: protein, total lipid, moisture, ash, carbohydrate, and energy content. Mean counts of mesophiles, psychrotrophs, and coliforms at 35 degrees C were 4.17; 3.69 and 1.87 (log CFU/g), respectively. Levels of protein, total lipids, moisture, ashes and carbohydrates were 27.50; 7.83; 63.88%; 0.24%; and 0.55%, respectively, and energy content was 182.63 kcal/100g.Discussion: Results of microbiological analyses demonstrated that, although low, the final product showed to be contaminated. Contamination that occurred during the second grinding procedure may be an explanation for these bacterial counts. Also, the temperature used for fat fusion was not enough to eliminate thermoduric microorganisms. However, even with the presence of indicator microorganisms in the samples, none was contaminated by E. coli, sulfite-reducing Clostridium, S. aureus, Salmonella or L. monocytogenes. Physical-chemical analyses showed that the product had adequate nutritional quality. Based on these results, it was possible to conclude that protein material obtained in fat rendering showed characteristics that enable the use of this product as raw material for processed meat products. Besides, the present study was the first one to present scientific results in relation to edible by-products obtained in fat rendering, supplying important information for slaughterhouses and meat-processing plants. The study also produced relevant data on the innocuousness of the product, which may be used to guide decision-making of health inspectors.

DIGITAL ELEVATION MODEL VALIDATION WITH NO GROUND CONTROL: APPLICATION TO THE TOPODATA DEM IN BRAZIL
Resumo:
Digital Elevation Model (DEM) validation is often carried out by comparing the data with a set of ground control points. However, the quality of a DEM can also be considered in terms of shape realism. Beyond visual analysis, it can be verified that physical and statistical properties of the terrestrial relief are fulfilled. This approach is applied to an extract of Topodata, a DEM obtained by resampling the SRTM DEM over the Brazilian territory with a geostatistical approach. Several statistical indicators are computed, and they show that the quality of Topodata in terms of shape rendering is improved with regards to SRTM.

The number of papers on History of Mathematics Education presented at EBRAPEM (Brazilian Meeting of Graduate Students in Mathematics Education) has increased significantly between 2003 and 2008. This article presents a study with the aim of identifying themes, periods in focus, and sources and theoretical and methodological references used by the authors of the papers on History of Mathematics Education published in the proceedings of VII, VIII, IX, X, XI and XII EBRAPEM. The study indicates that the approach of ongoing research in History of Mathematics Education in Brazil has been similar to the approach of research in History of Education in general. However, the institutional separation between these two areas of investigation is noted as a factor rendering communication between both groups of researchers difficult.

This study has the objective of presenting a new suggestion to the public relations professional into the Brazilian fashion business, seeing that, besides promising and little explored, presents social-economic conditions that allow the profession actuation. For this, it has been deeply analyzed the social character of fashion history e its development parallel to the society historical and economic transformations, basing, then, the study of fashion history in Brazil. To understand contemporaneity and the relations which interlace on it, there were used two analyzes about nowadays social order, liquid pos-modernity, from Bauman; and the hypermodernity, from Lipovetsky. In this context, it‟s approached new ways of relating with marks and with products which, since their consumption, are prepared to posterior discard. In the accelerated scenario of marks and consumption, the human relations, more liquids and tenuous, create the urgent possibility of action from on communication professional, who knows to identify the consumers desires and foresee their needs, rendering the tenuous laces stronger and the relationships more solid. This is when the profession of public relations presents itself as a new proposal to create experiences and to tight the loose laces on the consumption era

In the last twenty years, and more expressively in the past decade, the search for improvement in the organ transplantation system has contributed to the achievement of positive results in the Brazilian statistics related to the survival of transplanted individuals. However, for a transplantation to be performed, a number of phases must be followed by professionals working in organ search services. The phase that generates the greatest tension is undoubtedly that of family interviews, as it involves both the feelings of relatives who are facing a recent loss and those of interviewers who need to know how to deal with families at this time. The goal of this study was to apprehend perceptions of professionals working for an Organ Search Organization concerning interviews with relatives of potential donors. The qualitative methodology was used by adopting the Collective Subject Discourse for data organization. Interviews were conducted with six staff members of an organ search service whose experience as interviewers comprised from eight to fourteen years of work. It was possible to apprehend the professionals’ perceptions of family interviews and identify facilitating and hindering factors in this phase of the donation process. Such factors mainly involve: contact with the teams assisting patients, the difficult moment that families are experiencing and the teams’ as well as the institution’s preparation for rendering this type of service. The balance between the offer of and demand for organs in Brazil will only be achieved by means of an efficient and effective structure in transplantation organ search services and increased donation consent rates to be obtained by adequate communication between interviewers and relatives

This research is being read, thus rendering text on the pole of understanding, as a practice effective dialogue and therefore responsive through which the reader, author, text and context interact. To this end, the reader must turn their knowledge systems and relate them to the linguistic materiality. Thus, aimed to investigate whether the teaching of reading in the early years of elementary school literacy builds skills related to this cultural practice and its relationship to the conceptions of classroom teachers of reading, as well as the teaching and learning methodologies practiced in class classroom. Therefore, I base this research on the theoretical basis of linguistic studies and expository sociointeractionist redefine that, among other things, the concepts of language, genre and text. As for the methodological framework, this study followed the methodology of literature research and fieldwork. The fieldwork took place from the perspective of observing the pedagogical practice of teaching reading, in order to investigate how the educational activities are conducted in a reading room for the third year of elementary school, part of the municipal education Bauru- SP. Were used as instruments of data collection the questionnaire given to school teachers and the school studied the direct observation of teaching practice of one of these professionals. The results of data analysis indicate that the teachers surveyed know key content for teaching reading, as well as renovations of the theoretical and methodological studies of reading, with the consequence that the practices of reading done in the classroom limit the role of student as a reader and does not guarantee the formation of the reader

New Yb3+, Er3+ and Tm3+ doped fluoro-phosphate glasses belonging to the system NaPO3–YF3–BaF2–CaF2 and containing up to 10 wt% of rare-earth ion fluorides were prepared and characterized by differential scanning calorimetry, absorption spectroscopy and up-conversion emission spectroscopy under excitation with a 975 nm laser diode. Transparent and homogeneous glass-ceramics have been reproducibly obtained with a view to manage the red, green and blue emission bands and generate white light. X-ray diffraction as well as electron microscopy techniques have confirmed the formation of fluorite-type cubic nanocrystals at the beginning of the crystallization process while complex nanocrystalline phases are formed after a longer heat-treatment. The prepared glass-ceramics exhibit high optical transparency even after 170 h of thermal treatment. An improvement of up-conversion emission intensity – from 10 to 160 times larger – was measured in the glass-ceramics when compared to the parent glass, suggesting an important incorporation of the rare-earth ions into the crystalline phase(s). The involved mechanisms and lifetime were described in detail as a function of heat-treatment time. Finally, a large range of designable color rendering (from orange to turquoise through white) can be observed in these materials by controlling the laser excitation power and the crystallization rate.
