Estudo do perfil térmico de fornos do tipo "caipira" utilizados pelo setor de cerâmica vermelha em parelhas na região Seridó-RN

The present study aimed to characterize the thermal profile of wood fired oven used by the red ceramic industry in Parelhas, in the Seridó region/RN, aiming to propose structural interventions that can contribute to increasing productivity and product quality, optimize wood consumption and mitigate existing losses during the burning process. The study was conducted at Cerâmica Esperança in the city of Parelhas -RN, Brazil, during the period from August 2012 to September 2013. Four treatments were performed with three replicates, ie, with, a total of 12 experimental units (burnings). In the first stage 4 treatments were performed with three replicates, totaling 12 experimental units (firings). In the second stage 2 treatments were performed with three replications, totaling 6 experimental units (firings). The physical characteristics of the wood were analyzed using standard NBR 11941 and NBR 7190 for basic density and moisture, respectively. The clay was used as a reference parameter for distinguishing treatments. For both the analysis and characterization was carried out using techniques of fluorescence X (XRF) rays, X-ray diffraction (XRD) analysis, particle size analysis (FA). In the first and second stages were monitored: the time during the firing process, the amount of wood used at each firing, the number of parts enfornadas for subsequent determination of the percentages of losses, but also product quality. To characterize the thermal profile of the oven, we measured the temperature at 15 points scored in the surface charge put into the oven. Measurements were taken every 30 minutes from preheat until the end of burning, using a pyrometer laser sight sighting from preheating until the end of burning. In the second step 12 metal cylinders distributed on the oven walls, and the cylinder end walls 8 of the furnace 2 and rollers on each side walls are installed equidistant to 17 cm from the soil and the surface 30 of the wall are installed. The cylinders distributed on the front were placed 50 cm above the furnace, and the base of the oven 20 cm distant from the ground. 10 also thermocouples were installed, and five thermocouples distributed 1.77 cm above the combustion chambers, and one thermocouple on each side, and three thermocouples in front of the oven. We carried out the measurements of the temperatures every 1 hour during the burning two hours in cooling the cylinders with a pyrometer and thermocouples for dattaloger. These were fixed with depth of 30 cm from the wall. After statistical analysis it was found that: the thermal profile of the furnace surface and at different heights was heterogeneous; and the ranges of density and moisture content of wood are within recommended for use as an energy source standards. We conclude that even at low temperatures reached during firing there was a significant production of good quality products, this is due to high concentrations of iron oxide and potassium oxide found in clay, which lowers the melting point of the piece. The average burn time for each step varied 650-2100 minutes wood consumption was on average 20 m3, product quality was on average 16% of first quality, 70% second, third and 5% to 10% loss . The distance between the wire and the surface of the oven was a significant parameter for all treatments, but with different variations, meaning that the wire should not be so generic and unique form, used as a criterion for completion of the burn process. The central part of the furnace was the area that reached higher temperature, and in a unified manner, with the highest concentration of top quality products. The ideal temperature curve, which provided the highest quality of ceramic products was achieved in the central part of the furnace

Políticas públicas e associativismo no RN: experiências populares

Rural Popular experiences, socially organized on the constructions of the dams at Espinharas River, Serra Negra do Norte, which have been investigated, have reached in positive results. Several institutions, such as the City and State Power, multilaterals, governmental and non-governmental financial organizations, commonly refer to the success of such experiences. What success are they referring to? Is it recognized by family rural workers? What about institutional parts, how do they evaluate such experience? Is there legal continuity on such association structure? What kinds of gains have there been with such experiences? Has the association structure become any stronger? In search for demystifying the process, it has been made a research on classic and contemporaneous authors, as well as the interview of ten institutional parts, and twenty rural parts involved on the process, as well as the analysis of thirty-eight of the associations. It was concluded that the applied social public policies had resulted in heterogeneous social-economical process that has fulfilled the first step of a planning (not yet documented, but know by some institutional parts which lead, and still lead such social initiative). In the coming years the associations are to have a great potential for development, with the dams, as well as other projects. This persistence and external support, when integrated may have great deeds come to reality

Sociedade civil no espaço de atuação com juventude: uma cartografia social

This report has as its objective the setting up of a social cartography, mapping and characterizing non-governmental organizations working with adolescents and young people (OSC) in the western districts of the city of Natal. Characteristics such as the profile, themes and principal activities, how the organizations fit into the public sector and their participation in social networks are observed. Thus common differences and similarities which serve as a means of indentification, take as reference the symbolic cartography of Boaventura of Sousa Santos. Since there are relatively few studies relating to civil society of Rio Grande do Norte and in particular, Natal, the starting point was the setting up of a database allowing for a general overview. Hence a panorama of the organizations could be observed: where they are located, when they were formed how they operate and their relationships with other sectors (the state, the market and civil society) in addition to basic facts and location. The principal lines of enquiry were a) the OSC which operate with the public comprising adolescents and young people and b) the OSC operating or having branches in four suburbs on the periphery of the western administrative region of the city (Felipe Camarão, Bom Pastor, Cidade Nova and Guararapes).The present report has identified the impacts of ongoing social transformation caused by the process of globalization ,by the various currently contested political projects which are as follows: the project of neoliberal globalized capitalism(hegemonic)and the project of social emancipation (contra-hegemonic),how these are seen from the local viewpoint and how they influence the profiles and operation of the cartographic organizations. The area of the OSC is a heterogenous one with political, cultural and ideological strains, characterized by its infiltration, its local/global and multicultural dimensions. As civil organizations are fundamental in the processes of transformation within society, and following the idea of social emancipation referred to by Boaventura Santos, the enquiry classified the organizations according to the afore-mentioned characteristics, establishing eight types of associations. These different types and their respective characteristics were analysed from a related perspective using the mechanisms of symbolic cartography: scale, projection and symbolisation. The theoretical references underpinning this research arise from the debate on civil society which becomes redefined as a result of the dispute involving the two afore-mentioned political projects. These demand the theoretical application of the comprehension of heterogeneity in its diversity and complexity together with the idea of social emancipation.The main authors consulted were Boaventura de Sousa Santos, Antonio Gramsci, through the texts translated by Marco Aurelio Nogueira; Carlos Nelson Coutinho and Alberto Rivera ,who supported the construction of the types of associations identified by the local reality.Finally this research enabled an understanding of the current form of social action happening in the Space of the Four Neighbourhoods (Espaço dos 4 Bairros) and how the distinct profiles analysed together with the ares of operation of the organizations define their emancipatory potencials within the following two poles: regulation/adaptation and emancipation/transformation

Uma educação tecida no corpo

In theory say the education as a knot of meanings made in the body. We take as a reference for demonstration of this argument the shows Folguedos, Guarnicê and Flor do Lírio and built within such spectacles cultural, symbolic and aesthetic meanings, which reveal the education woven in the body. Education that can happen not only in the formal space like the classroom or the university, but also in the area of art and the inclusion of individuals in the world of culture. So during the construction of the thesis we reflect on the following issues: what is the construction of culture and art that have in the Parafolclórico group? What way theses shows in their buildings bring significant elements that might compose an educational activity. How objectives sought asking the dichotomies present in the concepts of art and culture; critically systematize a work of artistic, cultural and educational production in the group, in addition to expanding the understanding of education, considering the body experiences. The phenomenological attitude of Merleau-Ponty, is a reference methodology of this study, which places the reference knowledge as a result of our experience in the world, our world lived. Thus, this study considers the experience of the researcher in the three shows in tariff, represented by scenes described, as a dancer and spectator. Therefore we understand that Folguedos, Guarnicê and Flor do Lírio in their artistic, aesthetic and cultural languages, allow many meanings that occur in the body, which invites the perception and extend the experience of the subject, demonstrating an education that allows sight and knowledge, seeking new sensations and experiences, we show our intimacy with the world, with the objects and with the other. The art is understood as virtuality, as a human creation that carries the reality and that allows many readings and experiences, each perception can recognize and know new horizons, having as base and material the culture. This entails the heterogeneous, is not closed but that individuals can interpret it entered and recognize the symbols they created the same way, confirming a unit. The art and culture show us significant evidences of an education woven in the body

PLANFOR: política compensatória para a inclusão na informalidade?

Study about the national politics on the professional education, under responsibility of the brazilian Work Department in 1990 years. Purposes to apprehend the results of the actions of the professional education in a basic level, offered by the National Plan of the worker qualification ( PLANFOR ), as well as the effects on the assisted exits, starting from the experience appreciated on the Plan of Qualification developed in the state of Maranhão between 1996 to 2000. It adopts a theoretical-methodological conception by an ontological nature, if being worth of categories as the one of totality and of mediation that together, makes possible the apprehension of a dialectical movement that happens among the analysis object, the professional education politics in a basic level, performed by PLANFOR and your context, the underdevelop and heterogeneous Brazilian capitalism and the consequent job market generalized precarious and informal, making possible that the reality investigated become to understood rationally. This paper uses the indirect documentation technique, instruments of the bibliographical research and documental research. This study is based on those that aren´t part of PLANFOR, qualified by professional education courses in basic level,they didn't get to be inserts at the formal job market, just occupying precarious occupations in the informal job market. Aims to presents and discusses the productive process and your restructuring globally in progress. It focuses at the impacts on the workers, the precariousness of the work that appears like a new phenomenon calls new informality. Talks about the particularity process of productive restructuring assumed in Brazil highlights, showing that the informality, was always a structural phenomenon in the country. Discusses about the professional qualification in the contemporary capitalism, specifying some of your theses. Shows in a historical view the process of appearance of the employment notions and competence, and the influence that it exercised on the reforms of the basic and professional education, as well as the implications of both in the politics of professional education in the country. Rescues the process of creation of PLANFOR, your official formulations and your organized bases, starting from the second half of the 1990 decade. Shows yet the continuos changes in the job market of Maranhão state, for after, starting from the reports expresses at the Plans of Qualification from the state, elaborated by the Group of Evaluation and Studies of the Poverty and the Politics addressed to the poverty from the Master degree Program in Public Politics, from the Federal University of Maranhão, analyzing the acting of PLANFOR in the State, your probable deficiencies, as results the changes verified in the conditions of occupation and the gains of the exits from the professional education courses in basic level

Entre saberes e práticas :a alfabetização de jovens e adultos no MOVA Belém

This research analyses the experience of the Alphabetization of Young and Adults Movement named Prof. Paulo Freire (MOVA Belém) in the time period 2001-2004. the study intends to reveal which knowledge/activities are constituent of pedagogical practices of popular alfhabetzers. It also intends to contribute with the registry in the history of alphabetization of young and adults in Belém, without any intention of making general the analyzed aspects. The research is characterized by the use of a qualitative approach of the type ethnographic, because it involves an analysis that considers at the same time the local and global aspects. It analysis documents produced in the period and uses semi-structured interviews for data construction. It tries to show living cues and experiences of the pedagogical activities found in the theoretical references of Brandão (2003), Freire (1979; 1987; 1992), Gadotti (1998; 2000), Ribeiro (1999; 2003), Santos (1995; 2000), Soares (1985; 1998; 2003) and other authors of alphabetization and popular education fields. This multiplicity of bibliographical and empirical references has produced a heterogeneous framework, that is much more complex and multifaceted than the one which would be constituted as the knowledge of the pedagogical, alphabetizer practice. It can not happen, however, an absolute concept that is clear and total that resumes significance and matter of the pedagogical, alphabetization practice of young and adults. So, the study establishes a relativism between them assuming as valid the ones that are of popular and democratic types. At last but not least, it intended to contribute to the history of the alphabetization of youngsters and adults in Belém with a popular education perspective without any pretension to turn the analyzed aspects into generalized ones

Análise da dinâmica espaço-temporal de macrófitas submersas mapeadas com técnicas hidroacústicas no reservatório de Taquaruçu, rio Paranapanema

O objetivo deste trabalho foi avaliar o desenvolvimento da vegetação submersa, em termos da altura dos dosséis, considerando as dimensões espaço e tempo, usando técnicas de hidroacústica. Foram realizados dez levantamentos de campo no período de outubro de 2009 a dezembro de 2010, para aquisição de pontos georreferenciados de altura dos dosséis, frequência de ocorrência de vegetação, bem como de profundidade. Medidas limnológicas também foram feitas, a fim de verificar se suas variações poderiam explicar a distribuição espacial das macrófitas. Os dados de vegetação foram analisados por levantamento e por profundidade; além disso, compuseram um banco de dados implementado em um Sistema de Informação Geográfica. Foram então interpolados e das superfícies resultantes foram geradas cartas, que indicam a distribuição espacial do crescimento ou decaimento da vegetação. Modelos em três dimensões dos dosséis foram produzidos, para representar a ocupação volumétrica das macrófitas submersas. Os resultados mostraram que houve significativa redução da infestação de um ano para outro. Observou-se, ainda, que os maiores dosséis concentram-se em uma profundidade de 2 a 4 m. O mapeamento identificou tanto áreas de crescimento quanto de decaimento, distribuídas de modo heterogêneo. Não foi possível observar relação direta das medidas limnológicas com a dinâmica da vegetação, pois não apresentaram variação espaço-temporal significativa. Foi possível estimar o volume ocupado pelas macrófitas submersas, e a tendência observada é de que o aumento de volume é precedido por uma aparente homogeneização dos dosséis.

Avaliação cinética e potencial do Nb2O5 obtido a partir de um complexo de nióbio para formação do oleato de metila através da reação de esterificação do ácido oleico

Among the heterogeneous catalysts materials made from niobium show up as an alternative to meet the demand of catalysts for biodiesel production. This study aims to evaluate the potential of a heterogeneous catalyst derived from a complex of niobium in the reaction of methyl esterification of oleic acid. The catalyst was synthesized after calcination at different temperatures of a niobium complex ((NH4)3[NbO(C2O4)3].H2O) generating a niobium oxide nanostructure with a different commercial niobium oxide used to synthesize the complex. The commercial niobium oxide, the complex niobium and niobium catalyst were characterized by thermogravimetry (TG and DTA), surface area analysis (BET), scanning electron microscopy (SEM) and X-ray diffraction (XRD), showing the catalyst has researched morphological and crystallographic indicating a catalytic potential higher than that of commercial niobium oxide characteristics. Factorial with central composite design point, with three factors (calcination temperature, molar ratio of alcohol/oleic acid and mass percentage of catalyst) was performed. Noting that the optimal experimental point was given by the complex calcination temperature of 600°C, a molar ratio alcohol/oleic acid of 3.007/1 and the catalyst mass percentage of 7.998%, with a conversion of 22.44% oleic acid in methyl oleate to 60 min of reaction. We performed a composite linear and quadratic regression to determine an optimal statistical point of the reaction, the temperature of calcination of the complex at 450°C, the molar ratio of alcohol/oleic acid 3.3408/1 and mass percentage of catalyst of 7.6833% . Kinetic modeling to estimate parameters for heterogeneous catalysis it set well the experimental results with a final conversion of 85.01% with 42.38% of catalyst and without catalyst at 240 min reaction was performed. Allowing to evaluate the catalyst catalytic studied has the potential to be used in biodiesel production

Estudo da produção de pectinase por fermentação em estado sólido utilizando pedúnculo de caju como substrato

Pectinolytic enzymes, or simply pectinases, are complex enzymes that degrade pectic polymers. They have many uses, such as fruit juice extraction and purification, textile fiber treatment and vegetal oil extraction. The aim of this work was to study the kinetics of pectinases production by solid-state fermentation, using dry cashew apple residue as substrate and the microorganism Aspergillus niger CCT 0916. The influence of the initial medium moisture and medium supplementation with a source of nitrogen and phosphorus was evaluated using the factorial experimental planning and response surface methodology. Ammonia sulphate and potassium phosphate were used as nitrogen and phosphorus source, respectively. The variables time of contact (T) and ratio volume solvent/fermented medium (RZ), in systems with and without agitation, were evaluated in order to study the best extraction condition of the produced enzyme. Washed and unwashed cashew apple residues were tested as the growth medium. The unwashed residue was obtained by drying the residue after the extraction of the juice, while the washed residue was obtained by water washing 5 times using the proportion of 1 kg pulp/2 liters of water. Samples were taken every 12 hours for moisture content, pH, protein, reducing sugars, polygalacturonase activity (PG) and viscosity reduction. The physical-chemical composition of the residues had different sugar and pectin levels. For the unwashed residue, the peak activity was reached with 40% of initial moisture content, 1% of nitrogen supplementation without phosphorus addition after 30 hours of process. These conditions led to 16 U/g of PG activity and 82% of viscosity reduction. The calculated models reached similar values to the experimental ones in the same process conditions: 15.55 U/g of PG and 79.57% of viscosity eduction. Similarly, the greatest enzyme production for washed residue was reached with 40% initial moisture content, 1% nitrogen supplementation without phosphorus addition after 22 hours of cultivation. In this condition it was obtained polygalacturonase activity of 9.84 U/g and viscosity reduction of 81.36%. These values are close to experimental values that were of 10.1 U/g and 81%, respectively. The conditions that led to the best PG activity results was the agitated one and the best extraction condition was obtained with 100 minutes of solvent/medium contact and RZ of 5 (mL/g)

Avaliação de catalisadores a base de carbeto e nitreto de molibdênio na obtenção de lactitol via hidrogenação da lactose

Seeking a greater appreciation of cheese whey was developed to process the hydrogenation of lactose for the production of lactitol, a polyol with high added value, using the catalyst Ni / activated carbon (15% and 20% nickel), the nitride Mo2N, the bimetallic carbide Ni-Mo/ activated carbon and carbide Mo2C. After synthesis, the prepared catalysts were analyzed by MEV, XRD, laser granulometry and B.E.T. The reactor used in catalytic hydrogenation of lactose was the type of bed mud with a pressure (68 atm), temperature (120 oC) and stirring speed (500 rpm) remained constant during the experiments. The system operated in batch mode for the solid and liquid and semi-continuous to gas. Besides the nature of the catalyst, we studied the influence of pH of reaction medium for Mo2C carbide as well as evaluating the character of the protein inhibitor and chloride ions on the activity of catalysts Ni (20%)/Activated Carbon and bimetallic carbide Ni-Mo/Activated Carbon. The decrease in protein levels was performed by coagulation with chitosan and adsorption of chloride ions was performed by ion exchange resins. In the process of protein adsorption and chloride ions, the maximum percentage extracted was about 74% and 79% respectively. The micrographs of the powders of Mo2C and Mo2N presented in the form of homogeneous clusters, whereas for the catalysts supported on activated carbon, microporous structure proved impregnated with small particles indicating the presence of metal. The results showed high conversion of lactose to lactitol 90% for the catalyst Ni (20%)/Activated Carbon at pH 6 and 46% for the carbide Mo2C pH 8 (after addition of NH4OH) using the commercial lactose. Monitoring the evolution of the constituents present in the reaction medium was made by liquid chromatography. A kinetic model of heterogeneous Langmuir Hinshelwood type was developed which showed that the estimated constants based catalysts promoted carbide and nitride with a certain speed the adsorption, desorption and production of lactitol

Análises estatísticas em redes complexas: propriedades topológicas, críticas e dinâmicas

In this thesis, we address two issues of broad conceptual and practical relevance in the study of complex networks. The first is associated with the topological characterization of networks while the second relates to dynamical processes that occur on top of them. Regarding the first line of study, we initially designed a model for networks growth where preferential attachment includes: (i) connectivity and (ii) homophily (links between sites with similar characteristics are more likely). From this, we observe that the competition between these two aspects leads to a heterogeneous pattern of connections with the topological properties of the network showing quite interesting results. In particular, we emphasize that there is a region where the characteristics of sites play an important role not only for the rate at which they get links, but also for the number of connections which occur between sites with similar and dissimilar characteristics. Finally, we investigate the spread of epidemics on the network topology developed, whereas its dissemination follows the rules of the contact process. Using Monte Carlo simulations, we show that the competition between states (infected/healthy) sites, induces a transition between an active phase (presence of sick) and an inactive (no sick). In this context, we estimate the critical point of the transition phase through the cumulant Binder and ratio between moments of the order parameter. Then, using finite size scaling analysis, we determine the critical exponents associated with this transition

Caracterização comportamental e distribuição de neurônios inibitórios em um modelo animal de autismo induzido por ácido valpróico

Autism comprises a heterogeneous group of neurodevelopmental disorders that affects the brain maturation and produces sensorial, motor, language and social interaction deficits in early childhood. Several studies have shown a major involvement of genetic factors leading to a predisposition to autism, which are possibly affected by environmental modulators during embryonic and post-natal life. Recent studies in animal models indicate that alterations in epigenetic control during development can generate neuronal maturation disturbances and produce a hyper-excitable circuit, resulting in typical symptoms of autism. In the animal model of autism induced by valproic acid (VPA) during rat pregnancy, behavioral, electrophysiological and cellular alterations have been reported which can also be observed in patients with autism. However, only a few studies have correlated behavioral alterations with the supposed neuronal hyper-excitability in this model. The aim of this project was to generate an animal model of autism by pre-natal exposure to VPA and evaluate the early post-natal development and pre-puberal (PND30) behavior in the offspring. Furthermore, we quantified the parvalbumin-positive neuronal distribution in the medial prefrontal cortex and Purkinje cells in the cerebellum of VPA animals. Our results show that VPA treatment induced developmental alterations, which were observed in behavioral changes as compared to vehicle-treated controls. VPA animals showed clear behavioral abnormalities such as hyperlocomotion, prolonged stereotipies and reduced social interaction with an unfamiliar mate. Cellular quantification revealed a decrease in the number of parvalbumin-positive interneurons in the anterior cingulate cortex and in the prelimbic cortex of the mPFC, suggesting an excitatory/inhibitory unbalance in this animal model of autism. Moreover, we also observed that the neuronal reduction occurred mainly in the cortical layers II/III and V/VI. We did not detect any change in the density of Purkinje neurons in the Crus I region of the cerebellar cortex. Together, our results strengthens the face validity of the VPA model in rats and shed light on specific changes in the inhibitory circuitry of the prefrontal cortex in this autism model. Further studies should address the challenges to clarify particular electrophysiological correlates of the cellular alterations in order to better understand the behavioral dysfunctions

Expressão imuno-histoquímica da e-caderina e da ß-catenina em carcinoma epidermóide oral com e sem metástase nodal

The adhesion molecules E-cadherin and β-catenin have been studied as possible markers to distinguish carcinomas with and without metastatic potential. The objective of this research was to study the imunohistochemistry expression of the E-cadherin and β-catenin in oral squamous cell carcinoma (OSCC), aiming to contribute for the better understanding of the biological behavior of this lesion. The sample consisted of 30 cases of OSCC, being 15 of tongue and 15 of lower lip. The profile and intensity of labeling and semi quantitative analysis of the percentage of immunopositive tumoral cells in membrane for E-cadherin and β-catenin had been related with the anatomical localization of the lesion, the presence or not of nodal metastasis and the histological grade of malignancy in the invasive front area of the tumor. It was registered the presence or not of cytoplasmic and nuclear labeling of the β-catenin. The results had been submitted to the statistical analysis, being used the Mann-Whitney Test, the Fisher Test and the Spearman Correlation Coefficient (α=0, 05). The results showed that the expression in membrane for E-cadherin and β-catenin was, predominantly, the heterogeneous profile in the lower lip and tongue carcinomas, as well as in the cases with and without nodal metastasis. It was not observed significant statistical difference between expression profile and amount of immunopositive cells for E-cadherin, β-catenin and the anatomical localization of the lesion and for the presence or not of nodal metastasis. However, there was significant difference of the reduced expression of these proteins with the high score of malignancy. It was verified that the expression of the β-catenin in cytoplasm was present in 22 (73.33%) of the 30 analyzed cases, and 6 cases (20%) showed nuclear expression. The statistical analysis detected significant association between the expression of the β-catenin in the cytoplasm with the histological grade of malignancy, being this molecule more frequently present in the cytoplasm in the cases of high score of malignancy. It was concluded that the reduced immunoexpression of these proteins in membrane can be related with the lowest cellular differentiation, as well as with the pattern of invasion in nests and isolated cells, demonstrated in the cases of OSCC with high histological grade of malignancy

A percepção de suporte organizacional dos novos servidores da Universidade Federal do Rio Grande do Norte

This work deals with organizational support perception-OSP. This is done considering staff global beliefs, value of their contributions, care and well being related of individuals in an organization. These issues has been have been present in many researches since the 80s. It is important to analyze this matter considering all the changes that occurred nationally and internationally in the academic environment, characterized as being diversified in academic and managerial level. This occurs especially in Brazil since Federal Universities and their agents have suffered impact and restructuring. The research has emphasized the technical-managerial as well as professor staff level at Universidade Federal do Rio Grande do Norte aiming to deal with their unsatisfaction upon social political support. Thus, there was participation of 259 staff that were admitted from 2003 to 2005 in many sectors and units of the university. These subjects were submitted to a social and demographical query through an application of a scale of organizational support perception-OSP. Descriptive and multivariate analysis was done considering factors (management style of higher command), material support, wages, work overload, social support at work and ascending levels). Results show that there a hierarchy of the analyzed factors, the factor social support at work as being the first one with 3,31%, the factor management style of the higher command in second with 3,30%, then followed by the factor social support at work with 2,92%, in a sequence the factor material support, factor overload with 2,49% in the fourth position, and in the fifth place, the factor ascending with an average of 2,33% and in last the factor wages with 2,20%. It is concluded that the factors related to the more positive attributions of the OSP (social support at work), in a sequence material support opposing from the most negative factors of the OSP (wages, overload, ascending) reveal a reality that points out that the OSP is very much related to the individualized actions of the members of the organization (leader-member-group) rather than on structure and institutionalized actions carried out at UFRN
