Implementação das diretrizes operacionais para a educação básica nas escolas do campo: embates e limitações do trabalho docente no Rio Grande do Norte

Considering the situation of neglect existing in Brazilian public education and, specially, in the process of rural schooling, this dissertation aims to analyze the process of implementation of the Operational Guidelines for Basic Education in Rural Schools (DOEBEC), regulatory framework of the national policy of rural education. On it, we analyze the conditions of teaching work in rural schools of Rio Grande do Norte (RN), in 2010. The sample of the survey has as reference the representativeness of the chosen universe in relation to the totality of rural schools belonging to the state of RN. To answer the goals of the research, we opted to present a critical analysis of the following points: 1) Implementation of the DOEBEC; 2) Conditions of teaching work and teaching training. The points or categories of research were chosen based in the determinations of the DOEBEC (Resolution CNE/CEB n. 01/2002). For the data collection in the referred schools, we opted for the realization of interviews with the teachers and managers of these teaching establishments, in 2010. It was also utilized, for the characterization of school attendance in rural schools of RN, in 2010, official statistical data available by the State Secretary of Education and Culture (SEEC/RN). The analysis of the statistical data and of the primary data collected in field research indicated that the conditions of teaching work are still an obstacle to the development of the educative work of the teacher in rural areas. According to interviews with the participants of the research, we realized that the DOEBEC, despite being sanctioned in 2002, were still dimly known and discussed by the interviewees of the referred schools in 2010. Thus, we propose that the implementation of the policy of rural education in RN, instituted by DOEBEC’s legal landmark, and reaffirmed by the Rio Grande do Norte’s Charter to Rural Education (Brazil, 2005), is rethought and reconsidered, in the sense of ensuring that the changes proposed in this legal text, inherent to the school functioning, to the conditions of teaching work, to the rural schools’ management, to the remuneration and valorization of teaching work, to the teaching training, to the conditions of school transport, among others, be turned into concrete actions to improve the quality of education offered in the rural schools of RN state.

Procedimentos legais e protocolos sobre a sistemática de aquisição de cadáveres na Universidade Federal do Rio Grande do Norte para o ensino de anatomia humana

A disponibilidade de cadáveres para estudo e pesquisa vinha sendo feita tradicionalmenteutilizando-se corpos não reclamados sem grandes formalidades. Com a complexidadejurídica, social, ética e moral dos tempos atuais, o simples encaminhamento dessescorpos ao Departamento de Morfologia da Universidade Federal do Rio Grande do Norte,passou a ser temido com o receio de transgredir a legislação penal. Isso desencadeouuma redução no número de cadáveres para as aulas práticas de Anatomia. Essarealidade levou o Departamento de Morfologia da Universidade Federal do Rio Grande doNorte a pesquisar mecanismos legais que solucionassem a escassez de cadáveres parao estudo e pesquisa. A metodologia utilizada constou de reuniões de discussão eapresentação de protocolos de aquisição de cadáveres com base na legislação vigente.Os resultados obtidos foram: (1) Publicação do provimento 093/2012 da CorregedoriaGeral da Justiça do Tribunal de Justiça do Estado do Rio Grande do Norte, que dispõesobre o registro de óbito dos cadáveres destinados às escolas de Medicina para fins deensino e pesquisa; (2) Elaboração de protocolos para aquisição de cadáveres nãoreclamados junto às instituições; (3) Programa de doadores voluntários na UniversidadeFederal do Rio Grande do Norte.Por fim, concluímos que o conhecimento das atribuiçõespor parte das instituições públicas e privada, bem como o programa de doação voluntáriaaumentaram a oferta de cadáveres para o ensino da Anatomia Humana na UniversidadeFederal do Rio Grande do Norte.

Whoever, its necessary a more frequent evaluation of the carried actions, in a way they can be adapted to the real community necessities, and, is fundamental the data accompaniment, for that these serve of base for planning and redirecting activities, in a way that we do not have only a reproduction of traditional practices, fragmented and isolated, but a truly substitution of the traditional practices and a new way of promoting health

Uma janela tropical: análise do desempenho luminoso de ambientes com aberturas sombreadas para o clima de Natal/RN

This master thesis introduces assessment procedures of daylighting performance in office rooms with shaded opening, recommendations for Natal-RN (Latitude 05,47' S, Longitude 35,11' W). The studies assume the need of window exterior shading in hot and humid climate buildings. The daylighting performance analyses are based on simulated results for three levels of illuminance (300,500 e 1000 lux) between 08h00 e 16h00, in rooms with 2,80 m height, 6 m large and 4 m, 6 m e 8 m depths, with a centered single opening, window wall ratio (20%, 40% e 60%), four orientations (North, East, South and West), and two types of sky (clear and partially cloudy). The sky characteristics were statistically determined based on hourly data from INPE-CRN solar and daylighting weather station. The lighting performance is resulted from dynamic computer simulation of 72 models using Troplux 3.12. The simulation results were assessed using a new parameter to quantify the use of interior daylighting, the useful percentage of daylight (PULN), which corresponds to the time fraction with satisfactory light, in accordance with the illuminance design. The passive zone depths are defined based on the PULN. Despite the failures of illuminance data from the weather station, the analyses ratified the high potential of daylighting for shaded rooms. The most influential variables on the lighting performance are the opening size and the illuminance of design, while the orientation is a little influential

Estudo paramétrico da segregação gravitacional na injeção contínua de vapor

Steam injection is the most used method of additional recovery for the extraction of heavy oil. In this type procedure is common to happen gravitational segregation and this phenomenon can affect the production of oil and therefore, it shoulds be considered in the projects of continuous steam injection. For many years, the gravitational segregation was not adequately considered in the calculation procedures in Reservoir Engineering. The effect of the gravity causes the segregation of fluids inside the porous media according to their densities. The results of simulation arising from reservoirs could provide the ability to deal with the gravity, and it became apparent that the effects of the gravity could significantly affect the performance of the reservoir. It know that the gravitational segregation can happen in almost every case where there is injection of light fluid, specially the steam, and occurs with greater intensity for viscous oil reservoirs. This work discusses the influence of some parameters of the rock-reservoir in segregation as viscosity, permeability, thickness, cover gas, porosity. From a model that shows the phenomenon with greater intensity, optimized some operational parameters as the rate flow rate steam, distance between the wells injector-producer, and interval of completion which contributed to the reduction in gravity override, thus increasing the oil recovery. It was shown a greater technical-economic viability for the model of distance between the wells 100 m. The analysis was performed using the simulator of CMG (Computer Modeling Group-Stars 2007.11, in which was observed by iterating between studied variables in heavy oil reservoirs with similar characteristics to Brazilian Northeast

Cinemática de partículas em fluidos de viscosidade variável com o tempo e sua aplicação na construção de poços de petróleo: avaliação durante paradas operacionais

The new oil reservoirs discoveries in onshore and ultra deep water offshore fields and complex trajectories require the optimization of procedures to reduce the stops operation during the well drilling, especially because the platforms and equipment high cost, and risks which are inherent to the operation. Among the most important aspects stands out the drilling fluids project and their behavior against different situations that may occur during the process. By means of sedimentation experiments, a correlation has been validated to determe the sedimentation particles velocity in variable viscosity fluids over time, applying the correction due to effective viscosity that is a shear rate and time function. The viscosity evolution over time was obtained by carrying out rheologic tests using a fixed shear rate, small enough to not interfere in the fluid gelling process. With the sedimentation particles velocity and the fluid viscosity over time equations an iterative procedure was proposed to determine the particles displacement over time. These equations were implemented in a case study to simulate the cuttings sedimentation generated in the oil well drilling during stops operation, especially in the connections and tripping, allowing the drilling fluid project in order to maintain the cuttings in suspension, avoiding risks, such as stuck pipe and in more drastic conditions, the loss of the well

Estudo comparativo da utilização do nitrogênio como fluido alternativo após a injeção de vapor

Currently, due to part of world is focalized to petroleum, many researches with this theme have been advanced to make possible the production into reservoirs which were classified as unviable. Because of geological and operational challenges presented to oil recovery, more and more efficient methods which are economically successful have been searched. In this background, steam flood is in evidence mainly when it is combined with other procedures to purpose low costs and high recovery factors. This work utilized nitrogen as an alternative fluid after steam flood to adjust the best combination of alternation between these fluids in terms of time and rate injection. To describe the simplified economic profile, many analysis based on liquid cumulative production were performed. The completion interval and injection fluid rates were fixed and the oil viscosity was ranged at 300 cP, 1.000 cP and 3.000 cP. The results defined, for each viscosity, one specific model indicating the best period to stop the introduction of steam and insertion of nitrogen, when the first injected fluid reached its economic limit. Simulations in physics model defined from one-eighth nine-spot inverted were realized using the commercial simulator Steam, Thermal and Advanced Processes Reservoir Simulator STARS of Computer Modelling Group CMG

Estudo dos parâmetros operacionais do processo de combustão in situ em reservatório de petróleo pesado

The occurrence of heavy oil reservoirs have increased substantially and, due to the high viscosity characteristic of this type of oil, conventional recovery methods can not be applied. Thermal methods have been studied for the recovery of this type of oil, with a main objective to reduce its viscosity, by increasing the reservoir temperature, favoring the mobility of the oil and allowing an increasing in the productivity rate of the fields. In situ combustion (ISC) is a thermal recovery method in which heat is produced inside the reservoir by the combustion of part of the oil with injected oxygen, contrasting with the injection of fluid that is heated in the surface for subsequent injection, which leads to loss heat during the trajectory to the reservoir. The ISC is a favorable method for recovery of heavy oil, but it is still difficult to be field implemented. This work had as an objective the parametric analysis of ISC process applied to a semi-synthetic reservoir with characteristics of the Brazilian Northeast reservoirs using vertical production and vertical injection wells, as the air flow injection and the wells completions. For the analysis, was used a commercial program for simulation of oil reservoirs using thermal processes, called Steam, Thermal and Advanced Processes Reservoir Simulator (STARS) from Computer Modelling Group (CMG). From the results it was possible to analyze the efficiency of the ISC process in heavy oil reservoirs by increasing the reservoir temperature, providing a large decrease in oil viscosity, increasing its mobility inside the reservoir, as well as the improvement in the quality of this oil and therefore increasing significantly its recovered fraction. Among the analyzed parameters, the flow rate of air injection was the one which had greater influence in ISC, obtaining higher recovery factor the higher is the flow rate of injection, due to the greater amount of oxygen while ensuring the maintenance of the combustion front
