Otimização de vazão de poços injetores em projeto de injeção de água utilizando simulação por linhas de fluxo

Until the early 90s, the simulation of fluid flow in oil reservoir basically used the numerical technique of finite differences. Since then, there was a big development in simulation technology based on streamlines, so that nowadays it is being used in several cases and it can represent the physical mechanisms that influence the fluid flow, such as compressibility, capillarity and gravitational segregation. Streamline-based flow simulation is a tool that can help enough in waterflood project management, because it provides important information not available through traditional simulation of finite differences and shows, in a direct way, the influence between injector well and producer well. This work presents the application of a methodology published in literature for optimizing water injection projects in modeling of a Brazilian Potiguar Basin reservoir that has a large number of wells. This methodology considers changes of injection well rates over time, based on information available through streamline simulation. This methodology reduces injection rates in wells of lower efficiency and increases injection rates in more efficient wells. In the proposed model, the methodology was effective. The optimized alternatives presented higher oil recovery associated with a lower water injection volume. This shows better efficiency and, consequently, reduction in costs. Considering the wide use of the water injection in oil fields, the positive outcome of the modeling is important, because it shows a case study of increasing of oil recovery achieved simply through better distribution of water injection rates

Simulador de dano à formação, aplicado ao Projeto e à execução da perfuração de poços de petróleo

With the high oil price variability, the petroleum and the reservoir engineers are usually face to face on how they can evaluate the well performance and productivity. They can improve high productivity from the well construction to the secondary recoveries, but they have never tried a measurement in the drilling operations about the lower productivity index. As a rule, frequently the drilling operations hear from the reservoir engineering and geology that, if there is a formation damage, probably some drilling operations practices were not done properly or the good practice in petroleum engineering or mud engineering were not observed. The study in this working search is an attempt of how to measure a formation damage just from the project drilling to the drilling operations, with datum from the fields in Brazilian northeast and putting into practice a Simulator developed from the modeling on the theory offered by different experts and sources in formation damage

Projeto, construção e análise de um prototipo vibracional em escala de bancada aplicável ao tratamento de água de produção de petróleo bruto, mediante inovadora operação híbrida de adsorção e auto-flotação

A self-flotator vibrational prototype electromechanical drive for treatment of oil and water emulsion or like emulsion is presented and evaluated. Oil production and refining to obtain derivatives is carried out under arrangements technically referred to as on-shore and off-shore, ie, on the continent and in the sea. In Brazil 80 % of the petroleum production is taken at sea and area of deployment and it cost scale are worrisome. It is associated, oily water production on a large scale, carrier 95% of the potential pollutant of activity whose final destination is the environment medium, terrestrial or maritime. Although diversified set of techniques and water treatment systems are in use or research, we propose an innovative system that operates in a sustainable way without chemical additives, for the good of the ecosystem. Labyrinth adsor-bent is used in metal spirals, and laboratory scale flow. Equipment and process patents are claimed. Treatments were performed at different flow rates and bands often monitored with control systems, some built, other bought for this purpose. Measurements of the levels of oil and grease (OGC) of efluents treaty remained within the range of legal framework under test conditions. Adsorbents were weighed before and after treatment for obtaining oil impregna-tion, the performance goal of vibratory action and treatment as a whole. Treatment technolo-gies in course are referenced, to compare performance, qualitatively and quantitatively. The vibration energy consumption is faced with and without conventional flotation and self-flotation. There are good prospects for the proposed, especially in reducing the residence time, by capillary action system. The impregnation dimensionless parameter was created and confronted with consecrated dimensionless parameters, on the vibrational version, such as Weber number and Froude number in quadratic form, referred to as vibrational criticality. Re-sults suggest limits to the vibration intensity

Qualidade de vida do servidor da Universidade Federal do Rio Grande do Norte em condição crônica de saúde

The study aimed to analyze the influence of chronic health conditions (CHC) on quality of life (QOL) of UFRN servers assaulted by CHC. It is a descriptive and cross-sectional study with prospective data and quantitative approach, accomplished in the ambulatory clinic of the Department of Server Assistance (DSA) of the Pro-Rectory of Human Resources, during three months. The sample was composed by accessibility, totaling 215 people, being 153 active and 62 inactive servers, in chronic health condition. The data were collected through the application of the sociodemographic characterization, health, environmental and laboral form, the Medical Outcome Study 36-Item Short Form (SF-36). The study was evaluated by the HUOL Ethics Committee (CAAE no. 0046.0.294.000.10), obtaining assent. The results were analyzed in the SPSS 15.0 program through the descriptive and inferential statistics. It was identified servants predominantly male (59,1%), under 60 years old, married or in stable union, Catholics, brown color, living in the capital and residents in own home. Regarding labor issues, there was a predominance of active servers technical-administrative with intermediate and medium level positions and small proportion of docents. Among the CHC, the non-communicable diseases - NCDs (95.8%) had a higher frequency, followed by persistent mental disorders - PMDs (18.6%) and, finally, the continuous and structural physical deficiency - CSPD (16.9 %). The QOL of servers was considered good, with a mean score of 72.5 points in the total score, with the most affected domains: physical (59.1), general health (66.2), bodily pain (66.3) and functional aspects (72.0). The mental health dimension (76.5) had a better average than the physical dimension (68.0 points). It was found that the decrease in QOL scores is significant statistically related to higher number of CHC (ρ <0.001), with no statistical significance regarding the functional situation (p = 0.259). The administrative technicians of elementary, primary, secondary levels and docents had the worst QOL scores. After the correlation analysis of CHC with the domains and dimensions of the SF-36, there was statistically significant, negative and weak correlation of the domains: functional aspect (ρ = 0.002, r = -0.207), physical aspects (ρ = 0.007; r = -0.183), vitality (ρ = 0.002, r = -0.213), social function (ρ = 0.000, r = -0.313), emotional aspects (ρ = 0.000, r = -0.293), mental health (ρ = 0.000 , r = -0.238), physical health dimension (ρ = 0.002, r = -0.210) and mental health dimension (ρ = 0.000, r = -0.298). The presence of PMD isolated or together, contributed to a lower SF-36 scores, being the domains variation of mean significant, except for bodily pain, general health and physical aspects. By correlating the categories of CHC and QOL, there was a weak correlation (r ≤ -0.376) and significant (ρ ≤ 0.011), mainly related to the NCD, PMDs and NCD + PMD, affecting the mental health, social function, emotional aspects, vitality and functional aspect domains. Front of the results, it was concludes that the servers quality of life is influenced by the CHC. Thus, it was inferred that the presence of CHC causes a negative effect on quality of life, leading the active and inactive servers to exposure their overall life activities and work over the years, due to the morbidity affected, mainly related to NCDs and PMDs.

Projeto Prevenir: uma pesquisa acerca das mudanças no perfil das infecções por DST/AIDS, com a perspectiva de detectar pontos vulneráveis da prevenção

Rio Grande do Norte is among the Brazilian States where the tourism and sexual violence increasingly grow in the country, occupying 4th place in 2004. Associated to this fact, it comes the problematic one of the contamination of the women by Sexually Transmitted Disease (STD). Studies in Brazil have presented a considerable increase of the STDs, caused through lack of suitable protection in the sexual relationships. Due to the biological and psychosocial vulnerability, besides failures or inconsistencies in the condom use associated to the raised taxes of sexual activity with different partners, the STDs constitute the main risk of health. Many difficulties are found by the confrontation of this problem. In this context, this project had as aim to evaluate the vulnerability of this population of sexually active women in Natal-RN Ponta Negra neighbourhood to the infections by STDs, such as, Candida sp., Vaginoses Bacterial, Trichomonas Vaginalis and Chlamydia sp., arisen with the explosion of the sex market, showing a current statistical panorama. It was possible to detect vulnerable points in prevention through patient anamnesis, where the study it showed: high number of partners (8,3% with more than five), low age of first relationship and not the use of condoms (31,8% sometimes use and 45,8% had not used in the first relationship). Already consolidated by the preventive cytopathologic examination, these data were strengthened by high incidence of causing agents of STDs (58,6%). In this way, it is clear that the sexuality must to be thought on the context of the deep economic and socio-cultural transformations in which pass societies, and mainly the ones concerning to the sexuality exercise and to the sex market. With the profile change of the infections, new demands are placed in relation to the risk factors. Therefore, it can be concluded that the prevention vulnerable points detected as more important had been the deficiency in self-perception and wareness of the risk existence among the studied women

A encruzilhada da vida política em assentamentos de reforma agrária no Rio Grande do Norte

The rural settlements represent a mark in the expensive historical process of fight by the land in Brazil. At first offer basic terms of survival, through the access the land and of the fundamental supports for exploration. At the same time, have stimulated organization forms politicizes of the families who manage to work with the new challenges of the everyday. The moment that follows the land conquest, and therefore, the settlements construction while life and work project, it is crossed for objective and subjective demands, with highlight for options of agricultural production and strategies of collective action. Originally formed as representation instance legitimates of the families - front to the government and social actors - the settlers associations are private spaces for political sociability, that guided by principles participative, can lead the settlers the new conquests through indeed democratic experiences. The goal of this work is to comprehend the participation forms in the scope of these associations and the way as that translates in life best terms for the group, from the settlements experiences located in the Territories of the Citizenship Mato Grande and Açu-Mossoró, in Rio Grande do Norte's State. The theoretical conceptions that guide this analysis are concentrate on discussions about democracy and participation (Patermam, Putnam, Bodernave) and in the reflections about the rural world (Medeiros, Martins, Woodman e Woodman and Bergamansco). About methodological, different point of view strategies were developed: The direct observation, the application in locate of questionnaires to the families settlers and interviews semi-structured with the internal leaderships. With that could verify that the participation forms in the associations operate in two heartfelt: Of a side, they promote assimilation opportunities of democratic abilities accompanied of notions of social rights and redefinition of political standards; Of another, it offers indeed the possibility of the settlers lead, with relative autonomy, the political organization and her changes in direction to a way of life that wish to have in the settling

Auta de Souza, a poeta de pele clara, um moreno doce : memória e cultura da intelectualidade afrodescendente no Rio Grande do Norte

In the first half of the twentieth century different groups of intellectuals were engaged in the pursuit of an ideal of Brazility. Thereon, two currents are perceived. The first was marked by a nostalgic bias about the past, being formulated by intellectuals from the region that was turning as Northeast. This group of intellectuals emphasized values and traditions of the agrarian aristocracy of the region that was losing visibility in the political and economic Brazil scene. Already the other current has a more modern and industrial feature, was formed by intellectuals from the Southeast that in detriment of the first, was rising. This group, on the other hand, was intended to give a new face to Brazil and break with the "roots" of our delay that in their view were linked to our agrarian past. This resulted in different perceptions and interpretations of our historical past, and the construction of different profiles to the Brazilian. Accordingly, our work seeks to understand how was produced the writing that silenced the mixed ancestry of Auta de Souza (1876-1901) considering the position that she should occupy in the intellectuals projects who were in charge of forming a memory for our state. Auta as a relevant historical character in this project of potiguares intellectuals, she was raised to the condition of a model woman and elected in the pantheon of the most beloved poets of Rio Grande do Norte, however, to occupy such prestigious position she had her racial ancestry concealed in the writings that these same intellectuals had written about her, what is still spreaded in memory and rituals places of religious and civic features

Trajetória dos assentamentos rurais financiados pelo crédito fundiário no estado do Rio Grande do Norte: uma análise da experiência do assentamento da fazenda Paz no município de Maxaranguape/RN

The market-assisted land reform (RAAM) has been constituted as an alternative of agrarian reform funded by the Programa Nacional do Crédito Fundiário (PNCF). It is a policy of acquisition, distribution and use of Earth ideologically disseminated and funded by the World Bank in the context of productive insertion of landless workers. Accordingly, this study seeks to analyze the trajectory of rural settlements financed by this policy, seeking to understand what factors promote or limit the process of rural development of those settlements. To do so, take as a reference case study of the Assentamento da Fazenda Paz, in the municipality of Maxaranguape in the State of Rio Grande do Norte. From the methodological point of view, bibliographical and documentary research were used, in addition to visits to the settlement and semi-structured interviews with the settlers, trade union leaders, consultants and technicians linked to the project. Assuming the reports of respondents, initially constructs the hypothesis that informal and formal institutions present in the Assentamento da Fazenda Paz were unable to effectively coordinate the actions of the agents. The results obtained showed the existence of a very complex undertaking, with a total area of 607 hectares and 80 families settled, endowed with good quality water and irrigation infrastructure, with assets of approximately R$ 5 million reais. Experience experienced by the settlers understood the development of complex systems of production and marketing of fruits and vegetables, with an emphasis on the cultivation of papaya in an area of 45 hectares based on modern irrigation system and extensive use of technology. Collective management of production, marketing, revenue and costs stood out as a major challenge for the settlers and their representative organisations, i.e. the Community Association and the cooperative. From this observation it was possible to identify two moments on the trajectory of the project: the first, between 2007-2011, considered by respondents as successful, in which the integration of public policies and abundant input of revenue from the commercialization of the fruits da Paz, mainly through the sale of papaya and pineapple in national and international markets, allowed an average remuneration of R$ 800.00 reais to R$ 1,000 reais seated/monthIn addition to the production of vegetables and other types of products for sale and consumption; the second, from 2012, characterized as a failure, due to the discontinuity of the cultivation, production and marketing of fruits based on the collective bargaining model deployed. Important factors explain the discontinuity of the project, including the model of agriculture implemented, difficulties related to the management of production, marketing and finance the venture, in addition to the breach of trust between the Board of the cooperative and the associates and the distancing of the governmental organizations more directly responsible for the project. It is therefore concluded that we must to rethink rural development as a multidimensional phenomenon, requiring a broad engagement between State and society under the foundations of a territorial development contract

O Projeto político-pedagógico na perspectiva de consolidação da cultura organizacional e da autonomia da escola

In this research, we have found that, besides the literature in educational area presents the politic-pedagogical project as a pedagogical component that is able to promote changes in educational practices and to consolidate the school autonomy, some researches point to an opposite view-point, mainly due to the fact that these researches verify that several schools have elaborated their project just to comply with a formal exigency of the Brazilian educational reform implemented from the 1990 decade. Despite of the neoliberal and neoconservative forces (that guide this reform) understand the politic-pedagogical project as a way of stimulating scholar organizations, in order to put in practice the educational politics of this decade, we understand that this project can, in fact, promote changes in the scholar practices in the sense of overcoming the bureaucratic scholar culture historically developed in this environment. This research presumes that the process of planning, implementation and evaluation of school actions that is excited by the politic-pedagogical project can stimulate the subjects to develop practices, values, and senses, bypassing in some aspects the culture that is traditionally instituted in school, what will certainly favor the construction of its autonomy. The research that we have done in Professor Ascendino de Almeida Municipal School situated in the South Zone of Natal, RN, Brazil, was developed according to the following methodological procedures: document analysis, semi-structured interview, and participative observation. In the focused school we evidence that the politic-pedagogical project is a product of interpersonal and professional relations that are marked by shared powers, by dialogical action, by participation, and by equality, that (all of them) mediate decisional processes, what makes it possible the construction of common senses in order to guide the educative action. We yet evidence the existence, between the professionals that integrate this institution, of a culture for valuation of planning, of collective reflection, and of theoretical support, besides a commitment with the formation of the student with who they work, this making possible that the politic-pedagogical project constitutes in an orientation for the process of reflection, action, and evaluation of the school work. In these conditions, this project propitiates the consolidation of the school autonomy, what, in its turn, prints higher quality to the educative work developed in the institution

O ensino de matemática no Rio Grande do Norte: trajetória de uma Modernização (1950-1980)

This work aims to describe and analyze the process of the mathematics teacher modernizing in Rio Grande do Norte, in the period from 1950 to 1980. For that, we use as theoretical foundation assumptions of Cultural History and memories of the researchers Maurice Halbwach, Ecléa Bosi and Paul Thompson. As methodological tools, we used bibliographical resources and semi-structured interviews, in order to do a historical reconstruct of the mathematics educational scene of institutions and people who taught mathematics in Rio Grande do Norte, or those who participated in the modernization of the teaching of this subject, recovering their training and its practices in teaching. For the analysis of the bibliographical resources, initially we organized in a systematic way the transcripts of the interviews and documents, which were accumulated during the research, so long our thoughts, returning to the theoretical basis of this research, through questioning of knowledge acquired and that guided the problem of our study. The analysis showed that, important moments to modernize the teaching of mathematics in Rio Grande do Norte happened such: (1) Training Course of Lay Teachers in Rio Grande do Norte, in 1965, (2) Course for Teachers in Normal Schools, in 1971 (3) Satelite Project on Interdisciplinary Advanced Communications (SPIAC) in 1973; (4) Lectures of the teacher Malba Tahan, at Natal, from the end of the 50 s, that could be analyzed through the lessons notes of the teacher Maria Nalva Xavier de Albuquerque and the narrative of teacher Evaldo Rodrigues de Carvalho and (5) Courses of the Campaign for Improvement of Secondary Education and Broadcasting (CISEB). Thereby, the modernization of the school s mathematics teaching in Rio Grande do Norte, in the period from 1950 to 1980, was given mainly by disclosure of the Discovery Method and by the Set Theory contents in Teacher Training Courses

Políticas públicas de atendimento à criança: desafio da ação articulada no Projeto Belém Criança (2001-2004)

Public politics of Service to the Child: The Challenge of the Action Articulated in the Project Belém Criança (2001-2004) if it constitutes in a study on the politics directed toward the children of 0 the 6 years. It has as objective to analyze the configuration of the politics of integral attention to the child, evidencing the form as the same ones they had been redimensioned by the neoliberal ideas and by the lines of direction of the international organisms. The work has like empiric reference the project Belém Criança, developed by county of Belém from a partnership with the Deep of United Nations for Infancy (UNICEF), in the period of 2001 and 2004. The project intends to develop an articulated action among the several county departments which offer assistance to the children looking for to rationalize the resources and to optimize the services. Amongst the methodological procedures that materialized the research distinguished: The bibliographical review and documental allowed to analyze the contextualization of the public politics and, between them, the social politics of attendance to the child; the historical revolution this attendance; the paper of the UNICEF how articulator of the politics in municipal scope; and the paper of county how executer these politics. Still it was utilized, the half-structuralized interview, Having like subjects: the representative of the UNICEF in Belém, the municipal co-managers and actors of community in which the project was implemented. The result of the analyzes review that, historically, the politics destined to the child they had been being dimensioned having like support the fight of social movements vindictive for publics politic which guarantee the fundamentals rights these citizen. Although legal dimension of current politics of attendance to the child, to assume a vision of completeness and the guarantee of the rights, it still has a great exaggeration between the speech and the practical one. Actually, the same one are elaborate inside the neoliberal optics, with ruled actions by the beginning in combat to the poverty, implanted with low costs and with practice which to lead to the excessive fragmentation, generating inadequate actions and punctual programs which don t guarantee the social quality of the attendance. This perspective was evidenced to the most of the actors which the Project Belém Criança don t constitute itself a real public politic toward the child of 0 the 6 years, although present innovating aspects, how the mobilization and participation. It was demonstrated yet, in the participant s depositions of the research, that the bureau had numberless of difficulty to develop the action preview in the project, it has seen the great complexity of articulation between the several organism responsible by politics of attendance

A Associação Cultural Itapetinguense: um projeto de emancipação educacional e política para uma vila (1936-1961)

Este trabajo de pesquisa posee um carácter histórico y documental, teniendo como objetivo la Associação Cultural Ipapetinguense fundada em el año de 1936, por la dedicación de los hombres de la élite ganadera se congregarem para la lectura de los periódicos existentes en aquella época en la villa de Itatinga, actualmente la ciudad de Itapetinga (BA). Conocer la ACI, representó evidenciar sus proyectos direccionados para la cultura y la enseñanza, desde su comienzo hasta el año de 1961, analizando los conocimientos vinculados en esos proyectos. Entre los mismos, examiamos detalladamente a Biblioteca Dr. Orlando Bahia y las iniciativas realizadas para la enseñanza: la Escola da ACI, el Curso de Ciências, Letras e Artes, el Ginásio Alfredo Dutra y la Escola Normal Juvino Oliveira, desde el punto de vista de los conocimientos socializados en estas acciones. Entendemos que estos saberes fueron sembrados por la lectura de los libros da la Biblioteca Dr. Orlando Bahia, lo que nos hizo analizar el acervo de la misma, para así percibir que estos libros fueroan los testigos de los conocimientos de los maestros en quel período de la história de la educación en Itapetinga. Ellos fueron y todavia son, no sólo, los portadores de los contenidos y de los saberes enseñados, mas los reveladores de un proyeto de la emancipación educativa y política para la villa de Itapetinga. Estudiar la história de la Associação Cultural Itapetinguense, sus proyetos dedicados para la cultura y para la educación nos ofreció la posibilidad de conocer la villa de Itapetinga y su trayectoria económica y social, su desarrollo cultural y el camino recorrido en su emancipación educativa y política. De esta manera, las acciones culturales y educativas impulsionadas por la ACI y direccionadas hacia la villa fueroan la posibilidad del progreso, del esclarecimiento y confirmación de uma élite en el ámbito económico y social local y de aumento en el ámbito de los conocimientos y de la educación formal del pueblo en su sentido amplio. Las fuentes citadas para la pesquisa fueron, fundamentalmente, los libros de las actas y los estatutos de la ACI, periódicos locales, y libros de registros de préstamo de la Biblioteca Dr. Orlando Bahia, además de todas las comunicaciones orales em las charlas realizadas

Projeto político-pedagógico: instrumento de ação educativa na Escola Municipal Ascendino de Almeida Natal-RN (2002-2003)

In this dissertation, we investigate the process of elaboration of the Political-Pedagogical Project in the Municipal School Ascendino de Almeida , situated in the west zone of Natal city, in Rio Grande do Norte State, Brazil. We performed a qualitative research, using information provided by several sources as: interviews carried out in the Municipal Department of Education and also in the mentioned School, document analysis, and literature reviews, mainly with the objective of knowing more about the complexity of this particular reality. This was done in order to establish a mediation between the actual reality and the social, political, and economic context that surrounds it. We analyze the Political-Pedagogical Project according to the visions of Education theoreticians, under the political-normative plan, and also as a process of educational planning that can collaborate significantly for the introduction of changes in school Education. This instrument of the educative action, as a fruit of the participation of the school community, may constitute itself in an important learning instrument of the participation in the social sphere, demanding from the educators the development of complex abilities so that they can construct the Project. In the data analysis, we describe and analyze the process of elaboration of the Political-Pedagogical Project of the mentioned School. We also determine how participation of the school community was constructed as well as the consequences of this envolvement. We also discuss the abilities they needed to develop, the process of studies and dialogues that gave support to the whole process, and the democratic participation in the school decisions, including a dialogical interaction

O desafio da parceria na implementação do PRONERA: o caso do projeto alfabetização cidadã no nordeste Paraense.

El desafío de la parcería en la implantación del PRONERA: el caso del Proyecto Alfabetización Ciudadana en Noreste de Pará se constituye en un estudio sobre las políticas públicas de educación del campo. El trabajo tiene como objeto de análisis la implantación del PRONERA, a partir del estudio de caso del Proyecto de Alfabetización Ciudadana en Noreste de Pará, con el objetivo de comprender como la parcería, principio operacional y metodológico propuesto por el PRONERA, se concretó en la implantación del Proyecto y cuales sus posibles implicaciones en las políticas públicas de educación del campo. Entre los procedimientos metodológicos, realizamos la investigación bibliográfica y documental que nos permitieron situar la educación del campo en términos históricos y políticos, sistematizar la constitución y la organización del PRONERA y reflexionar acerca de la parcería a partir de diferentes ópticas. Realizamos también la investigación de campo por medio de entrevistas semi-estructuradas, con el propósito de analizar la implantación del Proyecto da Alfabetización Ciudadana, a partir del dialogo con los actores sociales involucrados. Los resultados de las análisis indicaron que, históricamente, las políticas públicas de educación destinadas a las poblaciones de la zona rural fueron instituidas verticalmente, desvinculadas de la realidad del campo e incompatibles con las necesidades e intereses de los sujetos. Constatamos que, en período reciente, movimientos sociales del campo reivindican y proponen acciones que se establezcan como políticas públicas de educación del campo. Identificamos que el PRONERA resulta de ese movimiento y se presenta como anuncio de una política pública de educación del campo, teniendo como diferencial el hecho de ser un programa del gobierno federal idealizado fuera de la esfera gubernamental, construido por los movimientos sociales del campo y presentar, entre otras innovaciones, el modelo de parcería y la gestión compartida, participativa y democrática. En esta perspectiva, en este estudio de caso, se evidenció que la parcería, frente a los conflictos y las disputas entre sus miembros participantes, no es el problema de la implantación del PRONERA, sino su punto fuerte. De este modo, la parcería es uno de los elementos necesarios para la construcción de políticas públicas, en particular, de educación del campo, una vez que posibilita la interacción de instituciones públicas y movimientos sociales locales, atribuyendo legitimidad a la educación del campo. Al promover un proceso de aprendizaje democrático, la parcería se presenta como estrategia de democratización de la educación del campo.
