Tecendo Papéis:viagem pelos saberes e práticas do ensino de arte

Nowdays, recycling became a relevant social and educational aim among many other factors, which involve balance between man and nature. This study relates the experiences with the production of recycled handmade paper directed at the teaching in Universidade Federal do Rio Grande do Norte UFRN, and through workshops of carnauba recycled handcrafts papers as a pioneer activity accomplished at the Felix Rodrigues Foundation, in the city of Pendências, Açu Valley, Rio Grande do Norte. A bibliographic review was done about the history of handmade paper and a discussion about carnauba´s paper artistic possibilities in art-education. Analyses within the context of art teaching, accordingly to Ana Mae Barbosa´s triangle propose and, also, Buoro, Ostrower and Nachmanovitch´s pedagogy of art. It deals with a group of artisans in order to establish the nature of their relationship and the possibilities of achieving more ecological awareness. Finally, we intend to realize a dialogue with Morin and other authors

Tear identitário:a prática docente em arte como conhecimento compartilhado

This investigative tissue is about the formation of identification processes of teachers and pedagogical practice of Art, in Teresina city. This search comprised the sum of the needs presented, agreed upon with the teachers engaged in the process, it was developed through the establishment of interactive environment Loom Team where collaboration and critical reflection were steering actions to promote the understanding of existing connections or relations within the processes of identifications and the pedagogical practice of Art. The tissue is formed by the polyphonic plot of the critical reflection of nine teachers of Art who engaged voluntarily and this investigation of formative nature and a production of knowledge. All these teachers have degree and the course of artistic education and especial qualification in Fine Arts and/or Drawing. The texture, which we denominated Identification Loom: The pedagogical practice of Art as share knowledge is (de) (re) construction of knowledge resulting from the critical reflection, in an environment of collaboration, which may have implications and ethical political attitudes in the pedagogical practice of the group. Within this context, we pose the following question: - How does the pedagogical practice in Art influence and/or be influenced by the identification processes of the teachers, and how do they interfere with the search and manifestation of the knowledge involved and the investment in professionalization? In view of this query, we make use of the cooperative investigation, having social history as theoretical reference and as analytic perspective of interactive and dialogical-reflexive processes. Thus, social historic theory, cooperative approach and pedagogical practice were the major components of the plot. The methodological texture counted on the threads of dialogical reflexion, of mediation and of collaboration. The conceptual formulation, the recording in videos of classes and the narratives of formations were the main threads of the analytic substrate of the investigation. With this articulation, theses threads appear as developers of processes leading to a major approximation of the thought on the identity/alterity dialectical pair of the participants involved. The language within this plot had a decisive importance in all the moments of the search of signification, embracing and connecting the identification/alterative processes, the pedagogical practice of Art and the knowledge shared. In such processes involving (de) (re) construction, one can notice a close correlation of the triad social identity, pedagogical practice and knowledge shared. For this reason, the vigotskian, guetmanovian and kopnian theoretizations were the major framework for the analysis of conceptual formulations; and, as for discourse analysis, Baktin and Orlandi were our masters. For these teachers, the experience shared throughout the process of this typology of tri-axial investigation focused the experience of many theoretical and practical assumptions. Such an experience enabled them to state that this, with collaboration, can make reflection on the practice a starting and promoting element, within the individual level of self-management, in addition to being a space of (de)(re)construction of meanings, of knowledge and of reinvention per se

O lugar pedagógico da educação física na educação infantil: saberes (re)construídos na formação continuada do PAIDÉIA/UFRN

The present study aimed to investigate the overview of teachers in continuing education program who work in kindergarten, about the continuing education developed by the Paideia/UFRN through the Course of Specialization in Art Teaching and Physical Education in Childhood, having as key focus, the knowing / doing related to physical education in Childhood. From this general goal, it was elected some specific objectives as: to know the interests and expectations that motivated the teachers to participate of that referred training; the evaluation by teachers on regard of the continuing education proposed: boosters factors for possible changes in teaching activities regarding the practice of teaching physical education in kindergarten. The methodology took the principles and techniques of qualitative research strategy and the characteristics of descriptive and interpretive strategy. The locus of this research was the Course of Specialization in Art Education and Physical Education in childhood, having as the citizens of this research twenty three teachers taking that specialization course. For building and systematization of the data, we used the following tools and procedures: a questionnaire, a semi structured interview and documents analysis. The data was constructed based on the technique of content analysis, focusing the reflections and speech of the teachers about the creation of new meanings and senses for the knowing / doing in Physical Education. It was found, among other results, the need and quest for improvement of teacher education, in order to improve educational practice. It was also evident that the situations of dialogues (interactions with peers, with their professors and other professionals in the related area or not) were mentioned by most teachers in the course as a relevant moment of redefinition of knowledge. In relation to Physical Education, it was found that participation in the course of specialization provided the recognition of teaching practice of physical education as part of the curriculum and the importance of inclusion of its specificities in their educational planning. From these elaborations, we come to the conclusion that knowing the perspectives of the teachers about continuing education can contribute to the theoretical and methodological discussions in teachers education and the creation of new actions - projects and programs of continuing education constructing increasingly ways towards a successful teacher formation, able to provide new forms of acting in the educational context

Ferrugem da teca (Olivea neotectonae): novas ocorrências no Brasil e revisão do nome específico

O agente causal da ferrugem da teca (Olivea neotectonae) vem atacando as plantações de diversos países que possuem plantios naturais ou comerciais. Ocasiona desfolha intensa das plantas contribuindo para a redução da área fotossintética e consequentemente, a produção. Especialmente associado a viveiros, apresenta maior severidade em plantas com menos de 10 anos de idade. Como sintomas da infecção são observadas manchas marrons e como sinais, soros pulverulentos de cor amarelo alaranjado. em maio de 2009, estes sintomas e sinais foram observados em folhas de teca, provenientes do norte do estado do Mato Grosso, Maranhão, Tocantins e da região centro-oeste do estado São Paulo, recebidos pelo laboratório de Patologia Florestal da FCA UNESP-Botucatu. O objetivo do presente trabalho é fazer o registro dessas constatações nos estados brasileiros e uma breve revisão sobre a denominação correta do patógeno.

Análise da imagem digital para estimativa da área foliar em plantas de laranja Pêra

Objetivou-se, com o trabalho, avaliar dois métodos de estimativa da área foliar, em plantas de laranja Pêra, pela análise da imagem digital obtida com scanner e câmera fotográfica digital. Para determinar a área das folhas, um grupo de discos foi colocado sobre um leitor de scanner, sendo que a imagem obtida foi armazenada. Os mesmos grupos de discos foram fixados sobre cartolina branca e fotografados com câmera fotográfica digital. As imagens obtidas da câmera fotográfica e do scanner foram processadas utilizando ferramentas de um editor de imagem que permite a contagem de pixels de determinada cor, no caso verde. Para a comparação dos métodos, os discos foram submetidos a integrador óptico de área foliar modelo LICOR-3100, utilizando os mesmos agrupamentos. Foram coletadas 20 folhas (cinco em cada quadrante da planta) por parcela de um experimento para comparação de fertilizantes comerciais e doses de zinco, aplicados via foliar, em plantas de sete anos de idade. O experimento foi composto de sete tratamentos e quatro repetições, num total de 28 parcelas. Os dois métodos apresentaram alta correlação com a área estimada pelo integrador óptico de área, considerado como método de referência. O método da análise da imagem obtida com câmera fotográfica, na resolução de 5.0 megapixel, foi mais precisa quando comparada à área estimada pelo integrador óptico de área.

Desenvolvimento de um Sistema de Visão Global para uma Frota de Mini-Robôs Móveis

Navigation based on visual feedback for robots, working in a closed environment, can be obtained settling a camera in each robot (local vision system). However, this solution requests a camera and capacity of local processing for each robot. When possible, a global vision system is a cheapest solution for this problem. In this case, one or a little amount of cameras, covering all the workspace, can be shared by the entire team of robots, saving the cost of a great amount of cameras and the associated processing hardware needed in a local vision system. This work presents the implementation and experimental results of a global vision system for mobile mini-robots, using robot soccer as test platform. The proposed vision system consists of a camera, a frame grabber and a computer (PC) for image processing. The PC is responsible for the team motion control, based on the visual feedback, sending commands to the robots through a radio link. In order for the system to be able to unequivocally recognize each robot, each one has a label on its top, consisting of two colored circles. Image processing algorithms were developed for the eficient computation, in real time, of all objects position (robot and ball) and orientation (robot). A great problem found was to label the color, in real time, of each colored point of the image, in time-varying illumination conditions. To overcome this problem, an automatic camera calibration, based on clustering K-means algorithm, was implemented. This method guarantees that similar pixels will be clustered around a unique color class. The obtained experimental results shown that the position and orientation of each robot can be obtained with a precision of few millimeters. The updating of the position and orientation was attained in real time, analyzing 30 frames per second

Molecularly organized Langmuir-Blodgett films from a ruthenium biphosphine complex

Langmuir-Blodgett (LB) films from a ruthenium complex mer-[RuCl3 (dppb)(4-Mepy)] (dppb = PPh2 (CH2)(4)-PPh2; 4-Mepy = 4-methylpyridine), termed Ru-Pic, display a distinct color, which is different from the coloration exhibited by cast films or chloroform solutions. The solution and cast films are red, while the LB films are green-bluish. The manifestation of the blue color in the LB film finds its explanation in a unique absorption band at 690 nm, which is associated with the oxidation of the phosphine moieties. Fluorescence emission and absorption-reflection infrared spectroscopy measurements revealed the molecular organization in the LB films. In contrast, cast films showed a random distribution of complexes. Surface-enhanced Raman scattering was also used in an attempt to identify the main interactions in Ru-Pic.

DESENVOLVIMENTO DE UMA ESCALA em SILICONA PARA TONS DE PELE HUMANA

O autor desenvolveu em silicona uma escala de tonalidades de pele humana. Foram confeccionados vinte e sete corpos-de-prova em silicona acética (Silastic 732 RTV), pigmentados com óxidos de ferro e dióxido de titânio. A quantidade de silicona acética manteve-se constante (dois gramas) em todos os corpos-de-prova, e os pigmentos foram misturados a ela em várias proporções até a obtenção de vinte e sete diferentes tonalidades. Através da comparação da cor dos corpos-de-prova com a cor da pele de quarenta e um indivíduos, foram selecionados os cinco corpos-de-prova com as tonalidades que mais se igualavam à cor da pele dos pacientes, compondo, assim, um guia de tonalidades. Com a metodologia empregada, foi possível desenvolver uma escala de tonalidades de pele que poderá facilitar a definição do tom da pele do paciente quando da confecção de próteses faciais em silicona, permitindo economia de tempo e de material no momento da seleção da cor.
