Historiando a política de formação de professores em serviço da UFRN

Les préoccupations gérées par les changements de l éducation nationale poussés par les réformes mises en places par le gouvernement de Fernando Henrique Cardoso, notamment la politique nationale de formation de professeurs, et le besoin de connaître comment ces réformes ont été incorporées par l Université Fédérale de Rio Grande do Norte - UFRN, constituent les questions centrales développées par cette thèse. Cette étude propose à montrer, à partir d une approche socio-historique, la façon comment la législation éducationnelle brésilienne sur la formation de professeurs pour l éducation basique expresse la politique de l État brésilien et, en même temps, comment le PROBÁSICA signifie une réponse de l UFRN à cette politique. En ce sens, cette recherche, selon sa perspective exploratoire, descriptive et analytique a privilégié plusieurs techniques et procédés de collectes des données conforme au modèle de la recherche participative, à savoir : enquête semi- structurée, observations directes, contacts formels et informels; enregistrement des opinions de professeurs, coordinateurs pédagogiques et étudiants; repérage, systématisation et analyses de plusieurs documents. L analyse des données, qui a été faite d une façon fondamentalement qualitative, a révélé que le PROBÁSICA a sa genèse à l intérieur de l UFRN et représente, en même temps, une réponse de cette université à la demande de la catégorie et la politique de formation de professeurs. Nous espérons que cette étude suscite d autres recherches qui développent des discussions sur les relations entre l État brésilien, ses politiques éducationnelles et les pratiques pédagogiques de formation de professeurs

Respostas morfogênicas e estruturais de gramíneas tropicais em regime de corte no nordeste brasileiro

The production of forage grasses is directly related to the morphogenesis. The knowledge of the morphogenetic and structural variables of forage plants is important for determining appropriate conditions of grazing livestock to ensure efficient and sustainable. Thus the objective of this study was to evaluate morphogenetic and structural responses of three genera of grasses, Brachiaria, Panicum and Cenchrus in a cutting regime. The experimental design was randomized blocks with three replications and six treatments. After each section were evaluated for forage production, appearance and elongation rates of leaves and stem, phyllochron, final leaf length, number of living leaves, leaf lifespan, leaf senescence rate, tiller density and tiller dynamics. On forage yield the highest values were obtained in cultivars Xaraes, Piata and Massai. The tiller density was higher for cv Massai. It is concluded that the cultivars of Panicum and Brachiaria had a higher tillering dynamics in increasing the turnover rate of tissues that are indicators of forage production, assuming that the cultivars of these genera are predisposed to use forage in the Northeast

O Serviço Social nas operadoras de planos privados de assistência à saúde: demandas, atribuições e respostas profissionais

The present study deals with the exercise of professional social workers in private health care plans registered with the Regional Council of Medicine/RN, in the city of Natal/RN, with regards to the demands/tasks, work conditions, and the professional response, given the climate of restructuring the capital. The set of socio-historical transformations, as a results of the dynamic capitalist, is a process of new configurations in relation to state and society that interfere directly in relation to working conditions, social rights historically won by workers. In this context, the operator of health plans arises as a possibilities to provide services in health, through the logic of the market, in which the subjects of law, become consumers contributing to the displacement of the responsibilities of the State. Obligating workers to lessen the burden with the reproduction of their workforce. This involves changing societal context for social service, since it is one of the professions that are active in terms of the immediate social issue, and come as part of the collective worker. From qualitative research based on a theoretical and methodological perspective and critical dialectics, it was possible to unveil some features and trends of the exercise of(a) social operators in private health care plans. The survey results indicated that : a) the demands and duties for certain social service, are associated with the redevelopment of the capital, whose requirements and responsibilities professionals have with their needs, particularly the guarantee of profit, services rendered; b) in the conditions of work there is a trend of insecurity uncertainty and dismantling of professionals; c) the answers professionals suffer the limits and contradictions present in the daily training, mainly depending one the characteristics of management and operation of the operators, which has professional relative autonomy

A questão urbana e a produção acadêmica do Serviço Social brasileiro em foco

O artigo aborda a questão urbana como objeto de pesquisa do Serviço Social. Resulta de pesquisa teórica e de análise das produções sobre esta temática, tendo por base artigos dos anais dos Encontros Nacionais de Pesquisadores em Serviço Social (ENPESS), no período 2000-2010. A ampliação e diversidade de espaços sócio-ocupacionais não correspondem necessariamente ao desenvolvimento de pesquisas, com aprofundamento teórico-metodológico exigido pela complexidade da questão urbana na contemporaneidade. Há crescente interesse pela temática de pesquisadores, profissionais e estudantes e esforços de sistematização e pesquisa evidenciados no número de trabalhos e na busca de qualidade dos mesmos. Mas há também necessidade de aprofundamento teórico-metodológico para uma produção do conhecimento em consonância com o Projeto Ético-Politico, o que supõe construção de vias de superação da sociabilidade capitalista

Adição de policloreto de alumínio e remoção de peixes bentívoros como técnicas de restauração de lagos rasos do semiárido brasileiro

Eutrophication is the most common cause of water quality degradation in the world. This process occurs by excessive nutrients inputs, nitrogen and phosphorus, to the aquatic systems resulting in algal and cyanobacterial blooms. In shallow lakes these effects are pronounced due to the higher interaction of the lake with watershed, air and sediment. There are innumerous restoration techniques of eutrophied lakes with a range of successful results but there is only one case of successful lake restoration in Brazil: Paranoá Lake in Brasília city. The Brazilian semiarid region has many artificial lakes, named açudes, which are mostly eutrophic and shallow lakes. The eutrophication in these lakes is reported and the phytoplankton community is dominated by potentially toxic cyanobacteria species, mainly Cylindrospermopsis raciborskii. The aim of this thesis is to test techniques for water quality management which can be easily applied in Brazilian semiarid lakes. Results from a laboratory experiment suggest that the addition of a phosphorus sorbent clay associated with an aluminium based coagulant is an effective technique in removing soluble reactive phosphorus and reducing C. raciborskii growth rate – cyanobacteria potentially toxic dominant in reservoirs of Brazilian semiarid – but this effect is dependent on the biomass in the application moment. Results from a field experiment in mesocosm in a eutrophied lake showed that the addition of aluminium based coagulant and removal of benthivorous fish is more efficient in removing total phosphorus and chlorophyll-a from water column than the isolated application of one of the techniques. Lastly, laboratory tests showed that aluminium based coagulant exhibited good performance in removing turbidity and total phosphorus from water of six reservoirs but the efficiency was reduced by algal biomass and pH. The results of this study showed that the improvement in water quality of eutrophied reservoirs in semiarid region is possible through internal loading control by phosphorus precipitation and inactivation in sediments or inhibition of phosphorus release by benthivorous fishes, and also that these results show are additives in water quality improvement.

A satisfação e a intenção de continuidade de uso em servços de e-learning:validação empírica de um modelo aplicado no serviço público

The present study aims to investigate the constructs of Technological Readiness Index (TRI) and the Expectancy Disconfirmation Theory (EDT) as determinants of satisfaction and continuance intention use in e-learning services. Is proposed a theoretical model that seeks to measure the phenomenon suited to the needs of public organizations that offer distance learning course with the use of virtual platforms for employees. The research was conducted from a quantitative analytical approach, via online survey in a sample of 343 employees of 2 public organizations in RN who have had e-learning experience. The strategy of data analysis used multivariate analysis techniques, including structural equation modeling (SEM), operationalized by AMOS© software. The results showed that quality, quality disconfirmation, value and value disconfirmation positively impact on satisfaction, as well as disconfirmation usability, innovativeness and optimism. Likewise, satisfaction proved to be decisive for the purpose of continuance intention use. In addition, technological readiness and performance are strongly related. Based on the structural model found by the study, public organizations can implement e-learning services for employees focusing on improving learning and improving skills practiced in the organizational environment

Contra as Secas: a engenharia e as origens de um planejamento regional no nordeste brasileiro

Droughts surfaced in 1877 as a crucial problem for the birthing Brazilian nation. Engineers, who formed the country's technical and scientific elite, took it upon themselves to study, understand and fight the problem through planned actions of intervention on space. This work, based on proposals and discussions contained in engineering magazines and reports, aims to provide elements for the comprehension of how these systematized actions against droughts, in the Iate nineteenth and early twentieth century, contributed to spatial analysis and the formation of a (then-inexistent) regional and territorial planning discipline in Brazi!. Engineers, by taking up the position of masterminds in the country's modernization, guaranteed for themselves personal economic stability, social prestige and political power. By understanding nature, either as a resource to be exploited or an adversary to national progress, they contributed to the delimitation of the region now known as the Northeast. By seeking to understand the drought phenomenon, they created knowledge about the space they sought to intervene on; by constructing their projects amid political and economical difficulty, they changed the organizational structures of cities and country in the northeast. The proposals for açudes (Iarge water reservoirs) allowed the fixation of population and the resistance against droughts; the roads - railroads and automotive roadways - connected the sertão to the capitais and the coast, speeding up help to the affected populations during droughts and allowing the circulation of goods so as to strengthen the local economies in normal rimes. The adopted practices and techniques, adapted from foreign experience and developed through trial and improvement, were consolidated as an eminently spatial intervention course, even if a theoretical body of regional or territorial planning wasn't formed in Brazil. Regional Planning proper was first applied in the country in the Northeast itself, in the 1950s, based off an economical view of reality in order to achieve development. The engineer's work prior tothat date, however, cannot be dlsconsldered. It was proved that, despite facing financial and political hurdles, engineers had a profound commitment to the problem and intended to act systematically to transform the economical and social relations in the region, in order to be victorious in their struggle against droughts

Para que servem hoje nossas cozinhas? :uma análise de uso das cozinhas do Plano 100 (Natal-RN)

This work investigates the using of kitchens of the apartments of PLANO 100 in Natal-RN, through one method s set of the functional and behavior evaluation. The theme was selected through of the emergence of the many questions that sought to understand what manners how individuals relates to the constructed space, what was the possible changes caused by these relation, also verifying how this space interferes in a daily life of theirs users.

Avaliação da correlação entre os parâmetros, carbono orgânico total e elementos tóxicos, em solo de um posto de serviço e revenda de combustíveis

Today a major responsibility for the contamination of soil and groundwater and surface water are establishments known as gas stations of fuel which has attracted increasing attention from both the general population as the state agencies of environmental control due to leaks in storage tanks and mainly to disruption of pipe corrosion of tanks and pumping. Other services, like oil changes and car wash are also causes for concern in this type of establishment. These leaks can cause or waste produced, and the contamination of aquifers, serious health problems and public safety, since most of these stations located in urban areas. Based on this, the work was to evaluate soil contamination of a particular service station and fuel sales in the city of Natal, through the quantification of heavy metals like Cd, Cu, Cr, Ni, Pb, Zn of total organic carbon (TOC) and organic matter using different techniques such as optical emission spectrometry with inductively coupled plasma source (ICP OES), Total Organic Carbon analyzer and gravimetric analysis respectively. And also to characterize the soil through particle size analysis. Samples were taken in 21 georeferenced points and collected in the same period. The soils sampled in sampling stations P3, P5, P6, P10, P11, P12, P13, P14, P15, P17, P18 and P20 showed the smallest size fractions ranging from fine sand to medium sand. The other study sites ranged from fine sand to medium sand, except the point P8 showed that only the type size medium sand and P19, indicating a particle size of the coarse type. The small correlation of organic matter with the elements studied in this work suggests that these are not of anthropogenic origin but geochemical support

Acesso aos serviços odontológicos e incidência de cárie em adolescentes e fatores de risco em município do Nordeste Brasileiro, 2006

The aims of this study were to analyze the access of dental services by child population, to determine the prevalence of dental caries, gingivitis and malocclusion in resident children from the municipal district of Sobral Ceará and to evaluate the incidence of the dental decay in adolescents associated with the factors related to socioeconomic condition, access to health services and self-perception. This study had as main factor the multidisciplinary represented by the participation of health professional (doctors, dentists, nurses) in the development of the survey's initial reference; student from Human Sciences area to apply the structured questionnaire in domiciliary visits; statistics professionals in the orientation of the analysis to be held and family health team (community health agents, dentists and dental clinic assistants) in the scheduling of domiciliary visits and the accomplishment of oral exam. The sample was determined from the domicile record that included children born between 1990 and 1994 to develop the research Children health conditions in the municipal district of Sobral Ceará . The first sample comprised 3425 parents of children from 5 to 9 years old, living in the urban area at the municipal district of Sobral Ceará, aiming at identifying the most important factors associated to the access to dental service. From this sample, 1021 children were selected in a systematic way, for the accomplishment to the epidemiological study of decay, gingivitis and malocclusion. In the study's third phase, in order to arrange the group to be followed, 688 adolescents were examined and interviewed, by means of the active search from the 1021 individuals that had been previously examined. It was observed that 50.9% of the children had access to dental service at least once in a lifetime. Of this total, 65.3% accomplished it during the last year, and 85.4% of these did in public services, what allows to identify the importance of this sector in the access to dental services. It was observed that the factors that most affected the access to dental 129 services were related to socioeconomic condition, such as the access to health plan, the possession of toothbrush, garbage collecting, mother s schooling, sewerage treatment and malnutrition. In relation to oral diseases, an increase in the DMF-T index according the age was observed, from 0.10 in five years old to 1.66 in the nine years old, while with the dmf-t index, the inverse happened, since the index decreased from 3.59 in five years old to 2.69 in nine years old. In relation to gingivitis, an average 32.7% of the children presented gum bleeding. In what concerns malocclusion, it was observed that 60.3% of the children didn't present any problem, 30.17% had light malocclusion and 9.5% severe malocclusion. The average incidence of dental caries was 1.86 teeth per youngster. Among the studied variables, tooth pain in the last six months, mother's income and school snack, adjusted by the perception about the need of treatment, the mother's schooling and the dentist's appointment at least once in a lifetime, were the variables that presented positive relationship with the high incidence of dental caries on this population by logistic regression. Variables of socioeconomic nature, related to the access to health services and behavior and biological variables presented a relationship with the high caries incidence. The study point out to the need of developing health actions in a humanized way, by an oral health team effectively bound to the population's interest, with the great objective to provide, with the public health services managers, adequate conditions to improve oral health

Mortalidade infantil e condições socioeconômicas nas microrregiões do Nordeste Brasileiro

The study aims to answer the following question: what are the different profiles of infant mortality, according to demographic, socioeconomic, infrastructure and health care, for the micro-regions at the Northeast of Brazil? Thus, the main objective is to analyze the profiles or typologies associated mortality levels sociodemographic conditions of the micro-regions, in the year 2010. To this end, the databases of birth and death certificates of SIM and SINASC (DATASUS/MS), were taken from the 2010 population Census microdata and from SIDRA/IBGE. As a methodology, a weighted multiple linear regression model was used in the analysis in order to find the most significant variables in the explanation child mortality for the year 2010. Also a cluster analysis was performed, seeking evidence, initially, of homogeneous groups of micro-regions, from of the significant variables. The logit of the infant mortality rate was used as dependent variable, while variables such as demographic, socioeconomic, infrastructure and health care in the micro-regions were taken as the independent variables of the model. The Bayesian estimation technique was applied to the database of births and deaths, due to the inconvenient fact of underreporting and random fluctuations of small quantities in small areas. The techniques of Spatial Statistics were used to determine the spatial behavior of the distribution of rates from thematic maps. In conclusion, we used the method GoM (Grade of Membership), to find typologies of mortality, associated with the selected variables by micro-regions, in order to respond the main question of the study. The results points out to the formation of three profiles: Profile 1, high infant mortality and unfavorable social conditions; Profile 2, low infant mortality, with a median social conditions of life; and Profile 3, median and high infant mortality social conditions. With this classification, it was found that, out of 188 micro-regions, 20 (10%) fits the extreme profile 1, 59 (31.4%) was characterized in the extreme profile 2, 34 (18.1%) was characterized in the extreme profile 3 and only 9 (4.8%) was classified as amorphous profile. The other micro-regions framed up in the profiles mixed. Such profiles suggest the need for different interventions in terms of public policies aimed to reducing child mortality in the region

O município brasileiro e o direito fundamental do acesso à justiça: a prestação da assistência jurídica municipal ao necessitado

This scholarly work aims to investigate the feasibility and constitutionality of access to justice through the provision of full and free legal assistance by the Brazilian municipalities. Investigates the historical aspects of federalism in a global context, emphasizing the contributions left by American federalism. In the Brazilian context, emphasizing the importance of municipalities as federal entities and their outstanding characteristics, while addressing regional issues of federalism. Leanings to the more detailed analysis of the Brazilian municipalities, contextualizing its legal status, its independence and its constitutional powers. It is emphasized in the same way, the relevant transformations of Brazilian municipalities over the last twenty years of this Constitution of the Federative Republic of Brazil in 1988, especially the various constitutional amendments that affected the local autonomy and budgetary aspects, fiscal and skills, bringing significant changes to the municipalities. It is an approach to the concept of justice and deepening the studies on the fundamental right of access to justice in its various connotations. In this vein, it is a study on the legal advice provided in Brazil, especially the powers of the Public Defender of the States and Union, as well as the provision of such public service by Brazilian municipalities and its relevance to citizens in need. At this point, it deepens the relevance of the theme of this dissertation earning the implications of municipal performance in the provision of legal assistance provided to the needy, and the activity of the Municipal Attorney or legal counsel in conducting such a task and its implications for legal and procedural especially on the constitutionality or otherwise of the conduct of such public service, confronting the constitutional articles that are correlated with the subject. Within this context, evaluates the municipal legal assistance under the test of constitutionality, in particular the assistance given by the Executive, through the Municipal Attorney or specialized secretariats and that provided by the Legislature, although it only has the typical functions of legislating and control the municipal accounts, comes in a few municipalities in Brazil deploying sectors with the performance of legal services to the needy. At this point the thesis, one wonders if some important aspects of this activity such as political influence and patronage, very common in day-to-day municipal prosecutors and legal advisers, public employees or occupying commissioned positions within the municipal administrative structure in several municipalities throughout Brazil. Finally, there will be a conclusion as to the constitutionality of the service being done by presenting proposals and recommendations that may improve the municipal legal aid, allowing a constitutional backing to this important service is being provided in capital cities and municipalities throughout the length of Brazil

O serviço público de fornecimento de água nas regiões metropolitanas: cooperação entre entes da federação e desenvolvimento

This work aims to study the material conflict of jurisdiction as to the ownership of public water supply, between the municipalities and the Member States, in metropolitan areas. One of the important points of analysis is the realization of the fundamental right of access to water, a right that is implicit in the Constitution of 1988, being prevented from having their achievement considering the lack of definition of the ownership of the service. Knowing discussed the essential public service, in all its stages, it will realize it is a complex activity that depends for its operation, joint activities of federal entities and the society. In its pursuit of development (understood as better conditions of life), that in view of the Federal Law nº 11.445 of 2007 is the universal access to service, require the adoption of popular participation and the positive benefits of the state, such as planning. Moreover, it will find cooperation between federal entities (after the study of Brazilian federalism) peaceful solution to the conflict through the adoption of joint management or shared, depending on the factual situation and legal
