A política de formação continuada de professores do ensino médio no RN: limites e possibilidades

El trabajo titulado La Política de Formación Continua de Profesores de Enseñanza Media en RN: límites y posibilidades tiene como objetivo analizar la política de formación continua de profesores de Enseñanza Media implantada en Río Grande del Norte. Parte del supuesto de que las directrices de formación continuada se articulan conforme a los organismos internacionales que desde la década de 1990 extendieron por América Latina un modelo homogéneo de formación, que tiene como principales características la de constituir un servicio a través de la modalidad a distancia y teniendo a la escuela como principal locus. En Brasil, estas características se apoyan en la Ley de Directrices y Bases de Educación Nacional nº. 9.394/96. Este trabajo es parte de un estudio que se desarrolla desde 2004 por la base de investigación Políticas y Gestión de Educación llamada Factores que influyen en la productividad de la Escuela Media: un estudio en Río Grande del Norte. El estudio en cuestión se centra en la dimensión pedagógica de la referida investigación y analiza la política de formación continua del personal docente, y considera como dimensiones de análisis la formación continua promovida en el ámbito escolar, ofrecida por la SECD/RN en el marco de la autoformación. Para la realización del estudio se hizo una búsqueda bibliográfica y documental que permitió la comprensión del objeto de estudio. La investigación empírica se realizó mediante la aplicación de cuestionarios, con preguntas abiertas y cerradas, a los maestros de Enseñanza Media de RN, y a través de entrevistas, semi-estructuradas de naturaleza complementaria, a las coordinadoras estatales de programas dirigidos a la Enseñanza Media. El análisis de los datos obtenidos muestra que no hay en SECD/RN una programación específica para la formación continua de los docentes de ese nivel educativo. Los programas implantados son de carácter nacional, de índole focalizada y no prestan atención a la mayoría de los docentes. La formación continua desarrollada en el âmbito escolar es prácticamente inexistente, y se limita a reuniones y algunos seminarios, sin mucha repercusión en la práctica docente. En cuanto a la autoformación son pocos los profesores que tratan de mejorar su práctica pedagógica con cursos de capacitación. Por lo tanto, se percibe una laguna en la formación de esos profesores y la necesidad de implementar acciones generales de formación continua que favorezcan una mayor y mejor articulación entre la formación inicial y continua, entre la teoría y la práctica, desde una perspectiva transformadora, en el sentido de superar modelos tradicionales de formación que no han tenido repercusión en la práctica docente

A formação do pedagogo-professor no curso de pedagogia: limites e possibilidades na visão de professores formados no campus avançado de Patu da UERN

The inconclusive policies regarding the teaching background, specifically the Pedagogy Course, whose National Curricular Directives DCN were ratified by the Ministry of Education on April 4th 2006, have been causing protest from the various forces within the scope of the university, specifically in the Pedagogy Departments in which, through their professionals, express the several stands about the pedagogue profile, his/her professional acting field and a curriculum that meets the background needs of this professional. This paper tried to assess, from the viewpoint of the student who graduated from the Pedagogy Course and who acts in classroom in the first years of the Elementary School, to what extent this course meets the background needs of the professional who works as teacher. In specific terms it was this paper's objective to identify the most important background needs of teachers who graduated in Pedagogy, who act in the first years of the Elementary School; To list the contributions and limitations of the Pedagogy Course of CAJIM/UERN in the teachers' background, outlined by the graduates of the course; to raise suggestions for the improvement of the teachers' background in the Pedagogy Course of the CAJIM/UERN. In order to turn these objectives viable we opted for the qualitative approach in research, more precisely for the case study methodology, from which we used as instruments for the execution of the field work the observation in classrooms, semi-structured interviews which became the main instrument used for the data construction and analysis. The data analysis process took place through the content analysis technique based in Bardin (2000). The theoretical line is based on the studies from Schön (2000), Nóvoa (1997), Perrenoud (1993), Alarcão (2003), Ramalho (2003) we also used the National Curricular Directives which serve as current Parameter for the Pedagogy courses. The study indicated that the Pedagogy Course contributed for the personal and professional enrichment, however, difficulties in the theory-practice articulation are still present in the everyday life. The theoretical knowledge assimilated, though represent increments to the professional practice, are not enough to enable a pedagogical practice with excellence. There is a need to consider a curriculum in a dialectic perspective, configurator of social and cultural practices sustained by the reasoning as praxis, thus it must not be seen solely in a theoretical plan, mas as a process that builds itself between the acting and the reasoning.

O processo ensino-aprendizagem de história no ensino fundamental: seus limites, suas possibilidades

Study about the teaching-learning process in History, which intents to point limits and possibilities to this process, starting from its characterization and analysis and understanding of the concepts of history, time, society and culture, used by teachers and students. The field research was performed in the Municipal School of Basic Education Zumbi dos Palmares, located in the city of João Pessoa, Paraíba State, in the period between 1996 and 2006. To achieve the objective of the study, a number of research instruments were used, amongst which, interviews, questionnaires and exercises emphasizing conceptual learning. The theoretical-methodological premises of the qualitative research justify the use of these various instruments, and serve as base for the interpretation and analysis of the data. This study demonstrated that some limits and possibilities that are found in the teaching-learning process in History are originated in the school context of the 1st phase of basic education and remain in the 2nd phase of this education level, partly, because of the understanding that teachers and students have regarding the concepts of history, time, society and culture

Sistema de detecção e isolamento de falhas em sistemas dinâmicos baseado em identificação paramétrica

The present research aims at contributing to the area of detection and diagnosis of failure through the proposal of a new system architecture of detection and isolation of failures (FDI, Fault Detection and Isolation). The proposed architecture presents innovations related to the way the physical values monitored are linked to the FDI system and, as a consequence, the way the failures are detected, isolated and classified. A search for mathematical tools able to satisfy the objectives of the proposed architecture has pointed at the use of the Kalman Filter and its derivatives EKF (Extended Kalman Filter) and UKF (Unscented Kalman Filter). The use of the first one is efficient when the monitored process presents a linear relation among its physical values to be monitored and its out-put. The other two are proficient in case this dynamics is no-linear. After that, a short comparative of features and abilities in the context of failure detection concludes that the UFK system is a better alternative than the EKF one to compose the architecture of the FDI system proposed in case of processes of no-linear dynamics. The results shown in the end of the research refer to the linear and no-linear industrial processes. The efficiency of the proposed architecture may be observed since it has been applied to simulated and real processes. To conclude, the contributions of this thesis are found in the end of the text

Detecção e isolamento de falhas em sistemas dinâmicos baseados em redes neurais

This master dissertation presents the development of a fault detection and isolation system based in neural network. The system is composed of two parts: an identification subsystem and a classification subsystem. Both of the subsystems use neural network techniques with multilayer perceptron training algorithm. Two approaches for identifica-tion stage were analyzed. The fault classifier uses only residue signals from the identification subsystem. To validate the proposal we have done simulation and real experiments in a level system with two water reservoirs. Several faults were generated above this plant and the proposed fault detection system presented very acceptable behavior. In the end of this work we highlight the main difficulties found in real tests that do not exist when it works only with simulation environments

Sistema híbrido para detecção e diagnóstico de falhas em sistemas dinâmicos

The industries are getting more and more rigorous, when security is in question, no matter is to avoid financial damages due to accidents and low productivity, or when it s related to the environment protection. It was thinking about great world accidents around the world involving aircrafts and industrial process (nuclear, petrochemical and so on) that we decided to invest in systems that could detect fault and diagnosis (FDD) them. The FDD systems can avoid eventual fault helping man on the maintenance and exchange of defective equipments. Nowadays, the issues that involve detection, isolation, diagnose and the controlling of tolerance fault are gathering strength in the academic and industrial environment. It is based on this fact, in this work, we discuss the importance of techniques that can assist in the development of systems for Fault Detection and Diagnosis (FDD) and propose a hybrid method for FDD in dynamic systems. We present a brief history to contextualize the techniques used in working environments. The detection of fault in the proposed system is based on state observers in conjunction with other statistical techniques. The principal idea is to use the observer himself, in addition to serving as an analytical redundancy, in allowing the creation of a residue. This residue is used in FDD. A signature database assists in the identification of system faults, which based on the signatures derived from trend analysis of the residue signal and its difference, performs the classification of the faults based purely on a decision tree. This FDD system is tested and validated in two plants: a simulated plant with coupled tanks and didactic plant with industrial instrumentation. All collected results of those tests will be discussed

Folhetos de cordel entre realidade e ficção cotidiana: um estudo da mídia na construção do personagem Seu Lunga

In this work, from the case of Mr. Lunga, a character of the brazilian northeastern culture whose stories circulated orally until they turned into verses of cordel (regional literature illustrated by xylographic printing images), we intend to understand that gender of leaflet, as significant cultural product, like media, with specific language features that act as means of construction and transmission of realities. To understand this phenomenon of meaning production in the cordel media, we used hermeneutics as a method and applied the general theory of interpretation in six chosen leaflets. We worked with a constructivist perspective that grounds the discussion of everyday reality and fiction, concepts that are raised around the essence of the character that is real, but it is also part of the creative activities of poets, how both are interrelated and constitute the understanding that individuals have the real. From the analyzes, we realize that each poet presents the fields of significance of Mr. Lunga in a different way, based on subjectivity, intention and mediations between each of them and the discourses they produce. Each cordelist contributes in his own way of significance for the construction of the imaginary Mr. Lunga. The speech of the cordelists contains a number of elements that aim to legitimize as truth the actions described. In this confrontation, our goal in this work is to understand the construction of the fields of signification, where these discourses are located, the production of meaning around a character who is not in a finite field, but transits through many of them, making the boundaries between reality and fiction dynamic

O Mitsein e as perspectivas decisórias da autenticidade segundo a analítica existencial: ponderações ontológicas para além dos limites éticos e políticos do ser-com

The present work focuses in the question of being-wit-others (Mitsein) on Martin Heidegger s philosophy. To do so, it takes base on his pivotal scripts, such as Being and Time and Na Introduction to Philosophy, in which this theme is scrutinized. The development line adopted in this work consists in advancing the existential connection between the being-with-others question attained to Dasein s ontological relation in its terms of authenticity and inauthenticity. So on, it is necessary to comment é others philosophical elements that surround this alterity relationship, analyzing phenomenologically how being-in-the-world inflicts the Dasein in its deepest and more important choice aspects, which can direct Dasein to its authenticity or inauthenticity. Facing this decisory context, also shall be observed the way Dasein finds to share the truth in accordance with its interaction with others, and how this mode of being summarizes all ontological structure of man s comprehension. The truth works as an integrative element from which the Dasein cannot escape, being-with-others is an existential situation that Dasein is not able to stop itself from living (its life-in-progress). This work also contemplates the apparent contradiction of Dasein s been always unfolded in The They mode of being, in its everydayness and being like that interacting with others. As along as this question is developed, the work explains how it is possible to be authentic and resolute (as much as inauthentic) as the Dasein interscts with others, even though, there is no pre-defined rule for these ways of relationship between the Dasein and the others

O corpo no pensamento de Epicuro: limites e possibilidades

The theme that fits the perspective of this thesis comes from the interest of treating, in the Epicurean corpus, about the importance of the body and its manners of realization for understanding the thought of Epicurus of Samos. Based on the inferences contained in the texts that remained from Epicurus, we did an analysis of the aspects that characterize Epicurism as a thought that makes repeated references to the body as an instance of sensitivity. It was necessary, therefore, to discuss how the body is linked to the possibility of thought, and how the latter can be admitted as a body element. It is further understood that the atomistic physics converges to the idea that asserts natural phenomena as likely to be contained and explained by the observations that come from the senses which are manifested through the body. For this reason, it was also pertinent to reflect on the admission of the body as a key element for the interpretation of Epicurean thought, even under the constitution of language. The Epicurean construction about body image was also used for the interpretation and questioning of the dynamics that define the relationships between individuals, characterizing the koinonía of the garden through the notion of corporeal unity. It was defined, therefore, that the characterization of the action field of individuals who lived in the Epicurean garden revolves around the use of logos, with the dialogues coming from the exercise of philosophy for therapeutic purposes, which were able to introduce a specific mode of political action marked by the absence of strange interests of the notion of philía

Aspectos dinâmicos da água versus álcool e acetona por técnicas de congelamento

Water still represents, on its critical properties and phase transitions, a problem of current scientific interest, as a consequence of the countless open questions and of the inadequacy of the existent theoretical models, mainly related to the different solid and liquid phases that this substance possesses. For example, there are 13 known crystalline forms of water, and also amorphous phases. One of them, the amorphous ice of very high density (VHDA), was just recently observed. Other example is the anomalous behavior in the macroscopic density, which presents a maximum at the temperature of 277 K. In order to experimentally investigate the behavior of one of the liquid-solid phase transitions, the anomaly in its density and also the metastability, we used three different cooling techniques and, as comparison systems, we made use of the solvents: acetone and ethyl alcohol. The first studied cooling system employ a Peltier plate, a device recently developed, which makes use of small cubes made up of semiconductors to change heat among two surfaces; the second system is a commercial refrigerator, similar to the residential ones. Finally, the liquid nitrogen technique, which is used to refrigerate the samples in a container, in two ways: a very fast and other one, almost static. In those three systems, three Beckers of aluminum were used (with a volume of 80 ml, each), containing water, alcohol and acetone. They were closed and maintained at atmospheric pressure. Inside of each Becker were installed three thermocouples, disposed along the vertical axis of the Beckers, one close to the inferior surface, other to the medium level and the last one close the superior surface. A system of data acquisition was built via virtual instrumentation using as a central equipment a Data-Acquisition board. The temperature data were collected by the three thermocouples in the three Beckers, simultaneously, in function of freezing time. We will present the behavior of temperature versus freezing time for the three substances. The results show the characterization of the transitions of the liquid

O (in)imaginável elefante mal-ajambrado: a questão de limites entre o Ceará e o Rio Grande do Norte e o exame da formação espacial e identitária norte-rio-grandense na Primeira República

This study s main goal is to analyze the way the limits between Ceará and Rio Grande do Norte states, the so called Grossos matter, has been associated to the norte-rio-grandense spacial and identity formation during the first republic period. Thus, a consistet number of sources: RN and CE old newspapers, as well as a república from Natal and Fortaleza and o mossoroense ; historical drafts from the historical and geographical institute associated and historical, gographical and anthropological institute of Ceará; the Ação Cível Originária de nº 6 from the supreme federal tribunal and many other cartographies. The documents haven t been hierarchized, neither accepted as proof effects, but understood as the base matter for this text composition by the deconstruction of the analyzed discusses. In order to do that the ablação or bricolagem method, without quotations marks or long quotations themselves, has been used. Along the three analyzed charpters: the two phases the litigious was found, since its beginning yet in the XVIII century until 1888 and its return within the republic proclamation, in the 1920 resolution; the development of the documental, historical and identity dispute between IHGA-CE and IHG-RN; and, at last, the political game existing between the Albuquerque Maranhão oligarchy , Manuel Pereira Reis and Rui Barbosa, explaining the intentions, silent and miths built along the time by these intellectual participations

Psicologia e pobreza no Brasil: limites e perspectivas da produção de conhecimento e atuação do psicólogo

Poverty is a main theme in Brazil: according to official data, poverty reachs 70 million Brazilian people, and, between them, 20 million are unable to provide their basic needs. Psychology, as a welfare profession, and given its historical concerns with social actions, could not be away from this theme. Based on this, we ask: Which answers Psychology can provide, toward both the production of knowledge and the practice about social reality? The purpose of this paper is to investigate the psychological scientific production on poverty and the propositions, limits and impacts of psychological actions. We carried out a three stages documental based study analyzing Brazilian psychological literature: (1) online databases survey (312 papers identified); (2) 109 scientific abstracts accessed and coded; (3) selected 47 scientific papers read and analyzed. Results are presented in three sections: general description of the selected scientific production; characterization of the role of poverty in psychological literature; and themes presented at the papers. The academic production about the main theme (poverty) is dispersed, heterogeneous, and related to other fields of knowledge. Poverty is presented at these studies in many ways, such as: a criterium for sample design and the assessment of its psychological impacts; reports on professional experience with poor population; descriptions of this population group; relationship between poverty and others social themes; developmental and learning problems of poor children. In general, it appears that Psychology has improved the scientific production and experiences with poor population. However, it is necessary to build up theories and technical innovations and also to understand structural boundaries for professional practice with this population group

Limites e possibilidades da educação em saúde na estratégia de saúde da família de Pau dos Ferros/RN

A Estratégia Saúde da Família (ESF) apresenta-se como um espaço privilegiado para a efetivação de práticas de educação em saúde orientadas pelo diálogo entre o saber científico e o saber popular, uma vez que é nesse espaço de saúde que profissionais e indivíduos/família se interrelacionam, criam vínculos, dialogam e constroem soluções para o enfrentamento dos problemas de saúde da população. O objetivo geral deste estudo foi analisar os limites e as possibilidades de efetivação da educação em saúde voltada para a coletividade na ESF de Pau dos Ferros/RN. Nesse sentido, buscou-se conhecer as concepções de educação em saúde dos profissionais de nível universitário da ESF; observar onde as práticas de educação eram desenvolvidas; conhecer os conteúdos e metodologias utilizadas para a efetivação das práticas de educação em saúde e caracterizar os espaços onde tais práticas eram desenvolvidas. Trata-se de uma pesquisa qualitativa, de caráter descritivo-exploratório realizada junto a nove equipes localizadas na zona urbana do município. Foram investigados 28 profissionais que atuam nessas equipes, dentre os quais elencamos: quatro médicos, oito enfermeiros e dezesseis cirurgiões dentistas. Fez-se uso da entrevista semiestruturada e da observação baseada em princípios etnográficos. Os dados foram analisados com base na técnica de análise de conteúdo de Bardin. O estudo obedeceu aos aspectos éticos contidos na Resolução 196/96 que regulamenta as Pesquisas Envolvendo Seres Humanos. Os resultados apontam que as concepções e práticas de educação em saúde dos profissionais da ESF são orientadas por uma educação bancária , pautadas pela transmissão e reprodução de conhecimentos. As temáticas são desenvolvidas de forma verticalizada, dissonantes da realidade de vida e saúde dos usuários. As práticas educativas são ofertadas majoritariamente por enfermeiros e estudantes de graduação em estágio na USF. Em sua maioria não são planejadas em equipe, e estão direcionadas à prevenção de doenças, distanciando-se da promoção da saúde. As principais dificuldades apontadas para a efetivação da educação em saúde dizem respeito à dificuldade de trabalhar em equipe, à falta de apoio da gestão, à estrutura física inadequada e a pouca adesão dos profissionais as práticas educativas. Portanto, a educação em saúde praticada na ESF não consegue instrumentalizar os sujeitos para que estes tenham autonomia e possam tornar-se sujeitos de suas vidas, de sua história. A prática educativa centrada na transmissão de conhecimentos ainda é uma realidade presente na ESF, constituindo-se em um desafio a ser superado
