O processo de invenção de si: um estudo sobre a construção identitária de pedagogas em formação

This work was developed in the course of Pedagogy, Universidade Federal do Rio Grande do Norte. Aims to understand the process of identity construction of teachers and educators in initial training. We started from the idea that such process was made by a complex and interdependent movement, once it was an inventive phenomenon wrought by individuals who are authors and actors of the story of their "real life" (KAUFMANN). This identity is rooted in the trajectories and social biographical experiences (FERREIRA), relationships with the constructed and accumulated knowledge in this route (CHARLOT) and in the developing of a sense of cultural belonging institutionally constructed (Luckmann, Berger). Then, the training involves relationships with knowledge in several instances, considering the effects, in one hand, the historic-social production and, in another hand, from the positions of subject and their biographical itinerary, existential and formative. We used the methodology of the Comprehensive Interview (KAUFMANN; SILVA), associated with a network of theoretical references, empirical and very analytical and interpretive activity. She researcher also relied on the "sensitive listening" (BARBIER), empathic attitude of "listening / seeing" the subject, and the notion of "intellectual artisan" (MILLS). The individual interviews were supplemented by the Focus Group. The approach was multi-referential (ARDOINO; MACEDO), with the intertwining of different perspectives, allowing a more complex configuration and less reductionist. In the analysis and interpretation we located the starting point, genesis of identity whose dynamics is not rigidly determined, but localized in space-time that precedes entry into the initial training. It is the time of concerns, questions and reflections about what you want to be in the future professional life. In sequence, we saw the route, multifaceted process whose the direction is the increasing involvement of individuals with their training. This training is engendered by the relations with the curricular, extracurricular and discursive knowledge, as simultaneous dynamics of self training and socio training. The self training of the individuals, understanding the critical, ethic and authority reading of their own experiences, is also seen as an exercise of shared responsibility, it assumes that the relationship with others meanings and professor mediation. The socio training refers to the collective subject and turns to the historical production and diversified knowledge, and comprehension of the various training instances. Self training and socio training are both objects of negotiation, because they are provocative of new designs, and cultural and identity maps, mobilizing the senses towards new meanings of themselves and the professional reality. It is in this interdependence between what is historically produced and the experiences of the subjects, who we located the arrival, considering it as a radically incomplete process of the professional identity and the building itself.

Formação de professores, saberes, reflexividade e apropriação da cultura digital no Projeto Um Computador por Aluno (UCA)

This study investigates teacher training and cognitive practice of teachers in a Basic Education school that adopted the Project One Computer per Student (OCS) in their school routine. Its relevance consists in provide directions for the continuation of training activities on the Project and guide the teachers with their pedagogical practices using the laptop model one to one. The thesis defended is that the educator formation for social using of digital media (specially the laptops from the Project UCA) gives space to establish new sociotechnical relationships, of new social and professionals practices, new identitary components and a process of reflexivity and knowledge reconstruction to teach. We reaffirm the importance of reflexivity and appropriation of digital culture for the better development of teaching practice using the Information and Communication Technologies (ICTs), giving focus to the aspects of social and professional use of the technology. The study is part of the qualitative aspect and is a procedural tracking based on principles of ethnographic research. As procedures and methodological tools, were used: intensive observation of school environments, documental analysis, focal group, semi-structured questionnaires and semi-structured individual interviews. The research was held in a public school in the city of Parnamirim - RN. The subject sample relates to 17 teachers, coming from the elementary school I and II, Youth and Adult Education and High School, who went through the process of training UCA and having entered the laptops in their teaching. The research corpus is structured based on the messages built into the process of data collection and is analyzed based on principles of Content Analysis, specified by Laurence Bardin (2011). Was taken as theoretical reference studies by Tardif (2000; 2011), Pimenta (2009), Gorz (2004, 2005), Giddens (1991), Dewey, J. (1916), Boudieu (1994; 1999), Freire (1996; 2005), among others. The analysis indicates a process of reconstruction / revision of knowledge to teach and work in digital culture, being these knowledges guided by the experience of the subjects investigated. The reconstructed knowledges will be revealed from a categorization process. The following groups of knowledges: "technical knowledges", "didactic-methodological knowledges and knowledges of professionalization" were built on the assumption of ownership of digital culture in the educational context. The analysis confirms the appearance of new ways of sociability when acquiring other forms of acting and thinking ICTs, despite the environment adverse to the reflexivity shared among the teachers. Also reveals, based on the ownership concept present on the data analysis, the construction of meanings of belonging and transformation of individuals into social routes from the interweaving of the teaching practice with the digital culture. Emphasizes, finally, the importance of a training for use of ICTs that exceeds the instrumentation, in other words, what we call "technical knowledges", but taking on its structural basis the shared reflection, the opening for the ressignificance (new meaning) and reconstruction of new knowledges and practices and that really allows, to the teacher, the living of an experience capable of providing socio-technical transformations of their relationships

Luiz Antônio dos Santos Lima e o seu legado educacional (Natal/RN, 1910-1961)

This research aims to analyze the intellectual practice of Luiz Antônio Ferreira Souto dos Santos Lima. This is done considering the author´s legacy related to the History of Education in Rio Grande do Norte/Brazil in the time span of 1910 to 1961. Thus, the research is grounded on assumptions that rely on the Cultural History field. The research also dealt with dialogues between the author and Chartier (1990), Elias (1994), Morais (2003; 2006), as well as Gondra (2003). For the bibliographical research the work dealt with a vast array of documents such as newspapers called A República and Diário do Natal, Pedagogium, Revista do ensino, as well as state laws and decrees These documents were obtained at the Historical and Geographical Institute in Rio Grande do Norte. The research also dealt with School Bylaws and a medical doctoral thesis called Mental Hygiene and Education that was written by Luiz Antônio dos Santos Lima. Other documents were obtained at the State´s Public Archive, such as the Book of Honor, Work Records, Reports and Minutes of the General Directorate of Public Instruction Meetings. It was possible to infer that professor Luiz Antônio dos Santos Lima was teacher at Grupo Escolar Augusto Severo, the Atheneu as well as some local grade schools. The professor had a broad role in society, in administrative positions such as the Presidency of the Association of Teachers of Rio Grande do Norte, as Grade School Director in the School of Pharmacy and the State Education Department. He was also a member of the Academy of Arts and a partner at Historical and Geographical Institute in Rio Grande do Norte. The professor has also concerned with issues related to teaching good habits such as feeding, grooming, discipline, game morals, temperance, smoking, sex education; all of which necessary for the formation of healthy children. He was an enthusiast of an intuitive method and teaching lessons through practice, that he considered key elements in education. It is seen that professor Luiz Antônio dos Santos Lima had presence in the State´s health education and that his ideals were line with the ideal of modernity of the early twentieth century

A concepção de ensino sob medida na obra hygiene mental e educação (1927), de Luiz Antônio dos Santos Lima

This dissertation examines the concept of the personalized teaching proposed by the physician and educator from Rio Grande do Norte Luiz Antonio dos Santos Lima, in his doctoral thesis "Mental Hygiene and Education," published in 1927. To do so, we start from the assumption that this thinker appropriated part of the educational theory formulated by Èdouard Claparède - specifically, in the case of the teaching concepts of the personalized teaching and comprehensive education designed by the Swiss intellectual - and, considering the Brazilian social reality of early twentieth century, reframed these concepts, adapting them to the country context. To implement the proposed idea, the bibliographical study was the option chosen, and so was done through a theoretical research which had as a reference authors whose studies referred to the Brazilian historical moment in the late nineteenth and early twentieth century, our examined time frame. As for the understanding and the methodological analysis of discourse, seen as socially constructed, the Foucault postulations were studied under an analytical approach, in which the disciplinary society is analyzed from the relations of power and knowledge that exist in it. The main source of this research was the work of "Mental Hygiene and Education," published as a requirement to the obtainment of Luiz Antonio s medical degree by the Rio de Janeiro Medicine School. Thus, it was found that the conception of personalized learning to the comprehensive education of students, as proposed in the doctoral thesis of Luiz Antonio dos Santos Lima, was related to abnormalities of mental character that children could present. School education was thought in a way by the potiguar thinker that it could be applied as deep as the moral, intellectual and behavioral deviations of the individual were, making use of hygiene practices of the minds through a normalizing process towards a civilized and developed future of the Brazilian nation which would manage, watch and fix the thoughts of the school students

Avaliação da escória de siderurgia e de calcários como corretivos da acidez do solo no cultivo da alface

O presente trabalho objetivou avaliar os efeitos da escória de siderurgia e dos calcários magnesiano e dolomítico, na produção de matéria seca da alface (Lactuca sativa L.) e as alterações na sua nutrição e em alguns atributos químicos do solo. Os tratamentos consistiram dos corretivos calcário magnesiano e dolomítico e escória de siderurgia, em três doses: 2,36, 4,72 e 7,08 g por vaso. Utilizou-se o delineamento experimental inteiramente casualizado, com quatro repetições, em esquema fatorial 3x3+1 (três corretivos x três doses + testemunha). Todos os materiais corretivos aumentaram a produção de matéria seca da alface, porém destacaram-se os calcários, sendo que para a escória, a alta concentração do Mn na parte aérea limitou a produção. Na parte aérea da alface, os teores e quantidade acumulada de Ca, Mg e Cu aumentaram, e os teores de Mn e Zn não foram alterados com a aplicação dos corretivos. Todos os materiais corretivos foram eficientes na correção da acidez do solo, especialmente quando se utilizou calcário magnesiano. A escória de siderurgia não é o corretivo mais apropriado para a cultura da alface.

Uso da poda e de diferentes diâmetros de alporques sobre o desenvolvimento e o acúmulo de nutrientes de mudas de lichieira

O objetivo deste estudo foi avaliar os efeitos do diâmetro do caule e da poda de alporques sobre o desenvolvimento e o acúmulo de nutrientes em mudas de lichieira cultivadas em substrato. Para isso utilizou-se de alporques da variedade Bengal. O delineamento experimental foi o inteiramente casualizado, em esquema fatorial 3 x 2, com oito repetições, sendo três diâmetros do alporque: fino (1,0 ±0,5 cm); médio (2,0 ±0,5 cm) e grosso (3,0 ±0,5 cm), e alporques com e sem poda. As mudas de lichieira foram cultivadas durante 140 dias após o plantio dos alporques. Avaliaram-se a matéria seca das brotações da parte aérea e das raízes, e os teores de macro e micronutrientes. A melhor muda de lichieira foi obtida de alporque com diâmetro grosso, e podado. O alporque de diâmetro médio e fino não-podado, comparado ao podado, proporcionou maior desenvolvimento da muda de lichieira. O alporque com diâmetro grosso proporcionou maior acúmulo de nutrientes na parte aérea e na raiz da muda de lichieira.

Gestão da satisfação e fidelidade do cliente : um estudo dos fatores que influenciam na satisfação e fidelidade dos clientes corporativos de telefonia celular

The competition in the telecommunications industry has grown in Brazil since the privatization, forcing companies that are active in the market to a growing commitment to quality products and services in order to survive. In this context, this work aims to understand the main factors that influence the degree of satisfaction exists in respect of a mobile operator with its corporate customers. The research covered theoretical concepts and analytical models of quality management system and models of indices related to the measurement of customer satisfaction. For the field research was carried out in a practical application of the main approaches based on this thesis by a case study in corporate segment, through a questionnaire applied to 10 consultants and 40 corporate customers of that company. Comparing the results of research with the consultants and corporate clients there is the concern of respondents to the indicators that comprise the constructs of customer satisfaction, commitment calculated, the price index and the handling of complaints, denoting the dissatisfaction of the general assessment for corporate customers with the carrier, against its current expectations. It is concluded that the mobile operator of the telecommunications industry have a big challenge, after ten years of privatization and consequently the period of rapid expansion of customer base and with the depleted, retain corporate customers as highly strategic, thus avoiding that migrate to other companies. We emphasize the need for further research and analysis of different approaches through research and using the same models to specifically evaluate and measure customer satisfaction of mobile enterprise, to adjust the model to the national market. Finally, we suggest the creation of an effective customer loyalty program with a strategy of relationship and specific to the corporate sector of mobile telephony

Otimizações da transmissão de imagens em redes de sensores visuais sem fio explorando a relevância de monitoramento dos nós fontes e codificação DWT

The development of wireless sensor networks for control and monitoring functions has created a vibrant investigation scenario, covering since communication aspects to issues related with energy efficiency. When source sensors are endowed with cameras for visual monitoring, a new scope of challenges is raised, as transmission and monitoring requirements are considerably changed. Particularly, visual sensors collect data following a directional sensing model, altering the meaning of concepts as vicinity and redundancy but allowing the differentiation of source nodes by their sensing relevancies for the application. In such context, we propose the combined use of two differentiation strategies as a novel QoS parameter, exploring the sensing relevancies of source nodes and DWT image coding. This innovative approach supports a new scope of optimizations to improve the performance of visual sensor networks at the cost of a small reduction on the overall monitoring quality of the application. Besides definition of a new concept of relevance and the proposition of mechanisms to support its practical exploitation, we propose five different optimizations in the way images are transmitted in wireless visual sensor networks, aiming at energy saving, transmission with low delay and error recovery. Putting all these together, the proposed innovative differentiation strategies and the related optimizations open a relevant research trend, where the application monitoring requirements are used to guide a more efficient operation of sensor networks

Técnicas neuronais de agrupamentos aplicadas à detecção de anomalias em mamogramas digitais

This work proposes the development of an intelligent system for analysis of digital mammograms, capable to detect and to classify masses and microcalcifications. The digital mammograms will be pre-processed through techniques of digital processing of images with the purpose of adapting the image to the detection system and automatic classification of the existent calcifications in the suckles. The model adopted for the detection and classification of the mammograms uses the neural network of Kohonen by the algorithm Self Organization Map - SOM. The algorithm of Vector quantization, Kmeans it is also used with the same purpose of the SOM. An analysis of the performance of the two algorithms in the automatic classification of digital mammograms is developed. The developed system will aid the radiologist in the diagnosis and accompaniment of the development of abnormalities
