O ato pedagógico como ato gnosiológico em Paulo Freire ensinar como uma aventura criadora

La presente tesis doctoral tiene como objeto de estudio la visión epistemológica de Paulo Freire y como punto central su comprensión del acto pedagógico como un acto gnoseológico e sus consecuencias para la praxis docente. La tesis original afirma, que en la obra de Freire hay una comprensión sobre el conocimiento ubicando el acto pedagógico como una situación gnoseológica, comprensión esta, indispensable a una praxis educacional libertadora. Para identificar esa comprensión, la presente investigación de carácter bibliográfica y cualitativa fue realizada a partir de indicaciones del propio Paulo Freire sobre el acto de leer/estudiar y del abordaje hermenéutico de Hans-Georg Gadamer, utilizando el diálogo con los textos del autor, buscando los sentidos capaces de responder a las cuestiones desarrolladas en la tesis. El trabajo presenta, además de una pre-comprensión del tema, los resultados de los ejercicios dialógicos mantenidos con los textos de Freire sobre el conocimiento y la educación como situación gnoseológica. Oportunamente fueron construidos mapas conceptuales de los hallados de la autora, para una mejor visualización espacial del lector, así como de los diálogos con tres estudiosos del pensamiento de Paulo Freire. El pensamiento de Freire sobre el conocimiento y la educación como situación gnoseológica abarca las siguientes dimensiones, aparte de la dimensión epistemológica propiamente dicha: dimensión históricofilosófica; dimensión político-ideológica; dimensión comunicativa y dialógica; dimensión ética y estética; dimensión pedagógico-cultural; y dimensión institucional y de gestión. La comprensión por el educador de esas dimensiones bien como sobre el Ciclo de Enseñar y Aprender pueden contribuir de modo significativo para una praxis docente capaz de recorrer el camino del diálogo problematizador, aquel que puede tornar el acto pedagógico un acto verdaderamente gnoseológico, capaz de auxiliar hombres y mujeres en su proceso de humanización

Caracterização e avaliação do macro sistema urbano de distribuição de água de Natal RN

The aim of this study is to characterize and evaluate the Macro System of Regional Water Distribution Natal North (RNN) and Southern Regional Natal (RNS), covering 35% and 65% respectively of the Natal-RN City. The terms of the quality and quantity of water (surface and groundwater) were also evaluated in order to adjust the parameters that contribute to proper distribution and control in water reserves. The methodology of the work took place from collecting volumetric data of production capacity and distribution of the two treatment plants for Regional as well as the flow rates of wells. Yet the quantitative capacity of reservation, distribution and consumption of the main reservoirs, population numbers and consumption of members neighborhoods were collected. Data were tabulated and used in computational simulator EPANET to diagnose possible through the water balance, the offers and demands on the water supply system in the neighborhoods of the capital, linking them to specific distribution points. We also evaluated the wells in the levels of nitrate in water consumed. As a result it was found that some neighborhoods in the South Regional Natal, was ranked as critical supply situation: City of Hope, Lagoa Nova and Nova Descoberta, where demand exceeds supply. While in most Northern Regional Natal present deficiency in the supply system as: Lagoa Azul, the Parque dos Coqueiros, igapó, Amarante and Salinas. The rates of nitrate in the city were significant, but manageable with corrective and preventive measures. The averages were 12 mg /l-N in Candelária, 10 mg/l-N in Lagoa Nova, 9 mg/l-N in Satelite, 20 mg/l-N in Gramore and 15 mg/l-N in N. Sra. Apresentação. Therefore proper distribution of water abstracted and implementation of quality control ensures the supply required by the system, associated with preservation of Water Resources of the Metropolitan Region of Natal

A dupla poética do silêncio: uma análise de Fogo morto e Cartilha do silêncio.

This research presents a reading of the poetics of silence in the profile and actions of characters in Fogo morto, by Paraiba s novelist José Lins do Rego and Cartilha do silêncio, by Sergipe s writer José Francisco Costa Dantas. As a starting point, we intend to demonstrate, through analysis, how the traditional issue of patriarchy, installed in rural areas of Northeast Brazil, live their momentum of rise and decline in different social spaces within narratives. This article shows how man lives tensions caused by the socio-political changes that will gradually be deployed in their environment due to the process of transition from traditional to modern life. From this perspective, this reading encourages a critical reflection on the social space of the mills and farms at the time of their rise and decay, as well as the various gender relationships between the feminine and the masculine world. The analysis indicates that all the changes both in family and social space unfold a world of silent variants and this paper takes as its theoretical basis the concept of silence built from the reflections of Eni Puccinelli Orlandi (2002), Barros Lourival Holland (1990 ), Luiz Costa Lima (1974) and Marisa Simons (1999).

As provas metafísicas da existência de deus em René Descartes

Le but de cet article est de présenter les éléments de preuve de l existence de Dieu présentée dans les Méditationes Métaphysiques de René Descartes, en soulignant son importance et son rôle dans le projet philosophique cartésien. La recherche visait á comprendre comment Descartes, étant um homme de science, la recherche de Dieu dans le pilier et d assurer leur philosophie. Par consé quence que Descartes propose de remplacer lui promettant de construire une nouvelle science fondée sur des bases sûres. Ainsi, le texte suit um ordre qu une partie de doute méthodologique comme um élément essentiel pour surmonter une connaissance née de l incertitude et généralisée et d opinions comme étant de droite, pour finalement atteindre la vérité dans les sciencies, Grace à la découverte Du premier cours, le cogito, moi pensant, alors existantes. Trouvé cette certitude, le sujet qui a en elle l idée d um être infini qui contient toutes perfections et, comme Il fera la démonstration de la preuve a posteriori et a priori. Et donc cet être ne peut pas être considéré comme inexistant projet assurant Descartes

Dimensão educativa do trabalho: estudo de caso da associação de bordadeiras do Seridó ABS- Caicó/ Rio Grande do Norte

This current work s contains issues about the educative dimension of work and its organization s process and managing for it own professionals. It aims to understand how the skills and pedagogic process, in a educative praxis perspective. Are based in a new culture of work of education process an work managing by workers in Handcraft Association of Serido/ Caicó/ RN. It uses as a methodologic-theoric reference cases s study approach, selecting the procedures of part extructure interview. It was done with six embroidereses from the Handcraft Association. The research shows that the educative process of learning and knowledges construction, in the work and by the work. Those processes develop in exchange experiences net in a friendly economic environment and raise elements of a work culture personal that work there. The embroidereses learn how to embroid doing the job and this learning, a lot of times, is influenced by the life conditions, residence local and infantile work in the country area and the living to the urban area, particularly to Caicó. The knowledge relation between them is the matter fact in the embroider learning process that means a social relation based on the knowledge differences between their position in its structure involving the work division, that each handcraft maker knows every part of the embroider, type of work or machine type, step by step until the work is done. It involves decision, execution and machine movements repetition, the focus are the categories that fit in current flexible financial issue. They schedule the work at home so they have time to do other stuff. Most part of the production currently is done to obey de a certain request that aims as production target, being a homework. Another important issue is the embroider work time: time and experience that is within in the professional life and its knowledge representation of job/profession. This time is got as a acquisition process of certain a work dominion and self knowing; time added to changes that were being there practicing from the new characteristics in the furniture, clothes and towels that are in the introduction communicative and its effect. In this way this work include articulations process among skills, educative process and handcraft work organization that allowed the interpretation and finish, that are related to the case study and its developments: handcraft embroidered considered as a profession, money source not conventional where is not work available and a temporary activity while studyng, homework and flexible work

Segmentação fuzzy de objetos tridimensionais com propriedades texturais

Digital image segmentation is the process of assigning distinct labels to different objects in a digital image, and the fuzzy segmentation algorithm has been used successfully in the segmentation of images from several modalities. However, the traditional fuzzy segmentation algorithm fails to segment objects that are characterized by textures whose patterns cannot be successfully described by simple statistics computed over a very restricted area. In this paper we present an extension of the fuzzy segmentation algorithm that achieves the segmentation of textures by employing adaptive affinity functions as long as we extend the algorithm to tridimensional images. The adaptive affinity functions change the size of the area where they compute the texture descriptors, according to the characteristics of the texture being processed, while three dimensional images can be described as a finite set of two-dimensional images. The algorithm then segments the volume image with an appropriate calculation area for each texture, making it possible to produce good estimates of actual volumes of the target structures of the segmentation process. We will perform experiments with synthetic and real data in applications such as segmentation of medical imaging obtained from magnetic rosonance

A poesia ibero-americana de José de Anchieta

El poeta José de Anchieta, a través de sus poesías, contribuyó para la formación de la literatura en suelo brasileño. Con eso, él proporcionó un encuentro entre los dos mundos lo Nuevo y lo Viejo, América y Europa representados en la unión entre los pares antagónicos que son constantes en la poética anchietana, como lo sagrado y lo profano, la muerte y la vida, lo simple y lo erudito. Su poética traduce, por lo tanto, las huellas de la antropofagia cultural, en que el indio y el blanco son uno sólo; el pagano y el cristiano, juntos, caminan para el centro de sus ideologías concebidas por la catequesis y por el popular. En esa amalgama entre las culturas, él construye un nuevo código cultural-lingüístico-literario, formando una nueva identidad para la tierra brasileña, abriendo las puertas para el barroco. Sus poemas están en cuatro lenguas: portugués, tupí, latín y español. Y de ese conjunto, nuestra disertación analiza el corpus en lengua española, que en el suelo americano deja de ser española y se vuelve ibero-americana. Como fuentes de estudio crítico-teórico, nos basamos, como ejemplos, en las obras de Haroldo de Campos, Severo Sarduy, Eugênio D Ors, Lezama Lima, Oswald de Andrade, Alfredo Bosi, Massaud Moisés. Así, esta disertación muestra, por el medio de la poesía iberoamericana de José de Anchieta el rasgo del inicio de nuestra literatura así como del barroco americano y, además, conjuga su poesía dentro del espacio de los Clásicos una vez que se comunica con estos desde el proceso de su producción. En esa intercomunicación, José de Anchieta promueve una apertura para la consciencia poética que hace parte de los grandes poetas de la Literatura Universal. Él une el Brasil, con sus matas vírgenes, con su primitivismo, al Mundo, con su censura desmedida ante la visión del Paraíso

José Paulo Paes, Humanista

La présente recherche examine dans son ensemble l' uvre considérable du "paulista" José Paulo Paes da Silva (1926-1998).

La deuxième partie est consacrée à la lecture critique de sa poésie épigrammatique. La riche bibliographie qui est le résultat de l'effort intellectuel de l'écrivain, est consignée à la fin du volume. Il s'agit donc d'une étude ayant pour but d'esquisser la physionomie littéraire d'une personnalité qui a marqué de sa présence la culture brésilienne dans la seconde moitié du XXe siècle

Palavras da maldição: O Ceará de José Alcides Pinto entre símbolos e alegorias.

This work treats about the speeches that produced the crisis of symbols of Ceará, researching on matters and ways of expression of space between 1950s and 1970s. Therefore, we search discursive practices that since the end of nineteenth century built the identity of Ceará and in the middle of twentieth century produced the crisis of modes of seeing and telling the space in front of enunciations of the national modernization, especially with the emergence of politics by SUDENE to the Northeast, the progressive actions by Catholic Church, the defense of tradition by regional literature of union of Ceará Clã. The contradictions between the glorification and fear the modernization of Brazil produced on the space speeches that his identity would be fractured, that the old symbols of drought, cangaço, mysticism and colonels declined. Among analyzed speeches, we centered the analysis of Trilogia da Maldição formed of novels O Dragão, of 1964, Os Verdes Abutres da Colina and João Pinto de Maria: a biografia de um louco by José Alcides Pinto. In this novel, the enunciation of the crisis of symbologies about the space produced another aesthetic, the allegory, which, mixed with the mystical and melancholy, in search of ways to restore the language of the old themes Ceará, drop of Ceará the same stigma of anti-modern space, where the images of delay changed icons of a fractured identity in front of the modern streams, where the word was transformed in the dimension precarious and redeemer of the tradition, of old, of nature, of the plenitude of senses. In Jose Alcides, the colonel returns as the origin of the lost space, the drought is the revolt of God against the devil place, the apocalypse, the end imminent threat to the village, signs that fantastic, however, are in dialogue with the settings space and time in which they were produced

Circuitos espaciais de produção da atividade boneleira: o uso dos territórios de Caicó, Serra Negra do Norte e São José do Seridó

Cette étude a été fondée sur la reconaissance, la description et l'analyse du circuit spatial de la production de l activité des fabriques des casquettes dans la région du Seridó Potiguar. L activité des fabriques des casquettes est située dans les villes de Caicó, Serra Negra do Norte e São José do Seridó, qui forment le pôle de fabriques de casquettes, composé de soixante-quatre (64) unités de fabrication, le deuxième plus grand producteur de casquettes au Brésil. Dans la condition de base géographique, l'opérationnalisation du concept de circuits spatiales de la production a été essentielle à la compréhension de l'utilisation du territoire et de l'indivisibilité de l'espace, du fournisseur de matières premières au consommateur final, comprenant les étapes des matières premières, la main-d'oeuvre, le stockage, les transports, le commerce et la consommation dans la période actuelle, dans laquelle les instances de la production, la circulation, la distribution et de la consommation sont spatialement diffus. Sur la base de l'identification et de la localisation de ces étapes et des principaux acteurs impliqués dans la activité des fabriques de casquettes, une configuration de circuit spatial de la production a été élaborée, en s'interprétant l'utilisation des territoires par les instances productives. L'interprétation des étapes de production a identifié que les entreprises liées à l'Association Seridoense des Fabricants de Casquettes agissent plus efficacement sur le territoire que celles nonassociées, alors que toujours elles investissent dans des nouveaux équipements, en augmentant sa puissance technique pour se renforcer avant un marché si compétitif comme celui des casquettes. En examinant la contribution de la fabrication des casquettes à l'utilisation actuelle des territoires de la coupe, nous avons appris que les activités complémentaires et des matières premiéres nécessaires à sa réalisation se trouvent dans leur environnement géographique. Ainsi, la proximité spatiale entre les étapes de la fabrication des casquettes fait entrevoir la matérialité du territoire, conférée dans la coexistence des techniques passées et présentes, et l'ensemble des actions effectuées par un certain nombre de travailleurs sociaux qui collaborent à la création du circuit spatial de la production de l activité des fabriques des casquettes. Cette étude a confirmé que les fabriques des casquettes sont organisées sous la forme de cellules de production, continues ou discontinues, dont les équipements et les machines à coudre industrielles obéissent à la logique d'une production de plus en plus standardisée. Ce circuit spatial de la production contribue à l'utilisation actuelle des territoires de Caicó, Serra Negra do Norte et de São José do Seridó car il amplifie le mouvement du commerce et des relations entre les lieux, à travers la dynamique des flux des personnes, des biens et des produits, en constante circulation, guidées par la division du travail entre les étapes productives
