A noção de festa nas relações públicas: a comunicação comunitária na Feira da Vila Madalena

This paper aims to review the concept of Festival in the area of Public Relations and discuss about it according to the Classical Anthropology, Urban Anthropology and Public Relations theories, by their main exponents Emile Durkhein, Rita Amaral, Roberto Damatta and Joseph Guilherme Magnani, Waldemar Kunsch, Margarida Kunsch, Cicilia Peruzzo, Rennan Mafra and Márcio Simeone. The 33rd Vila Madalena Fair, a craft fair that takes place once a year in São Paulo, was chosen as a case study to provide this research with an empirical dimension. The Fair emerged as a result of the neighborhood residents and merchants´ mobilization in the late 70's and until today, has been responsible for the re-updating and the strengthening of the neighborhood identity. Thus, the proposal is to evaluate the possibilities of the Festival performance as a favorable strategy to sociability, to the strengthening and the re-updating the symbolic representations of a community

Proposta para melhoria da qualidade dos produtos cerâmicos e de criação de um polo cerâmico artesanal na cidade de Indiana - SP

This work presents a proposal to create a Polo Ceramic Craft in the town of Indiana - SP, through the potter’s organization in a cooperative that will coordinate activities to add value to ceramic pieces. To achieve this, two things are essential: improving the ceramic body and improve the properties of the ceramic material. For the first action it’s necessary to create a Central Mass Production of Ceramics, to provide raw materials and homogeneous composition that results in differentiated ceramic after burning process (sintering). To this end, we propose the incorporation of additives (which act as fluxes) to the clay material. These additives can be mineral such as feldspar and nefelinas or leavings, such as glass powder obtained from disposable containers. For the second action is necessary to acquire an oven, electric or gas, it reaches higher temperatures (around 1200 ° C). The presence of the additive and burning at higher temperatures will enable better production of sintered ceramic material with less porosity and water absorption and higher mechanical strength, and pieces vitrified and glazed, allowing them to assign a higher value. For the production of these materials (thinner walls) requires a smaller volume of clayey raw materials. Besides benefiting the ceramic pieces, the proposed changes reduce the environmental impact caused by burning wood, since it will be replaced by natural gas (or electricity), and even will reduce the disposal of glass containers in the environment by recycling and incorporating this material in the clay. From a social standpoint, the cooperative is crucial to the viability of the proposed project, to coordinate activities and commercial production, which will result in better wages and profits for companies and consequently for the city and its population

O dispositivo metodológico e interventivo autoconfrontação e seus usos em pesquisas de educação

This article presents an academic and scientific study about the use of the device methodological and intervening of selfconfrontation in research in post-graduate studies in Education in Brazil. The self-confrontation is a device created by linguist Daniel Faïta and perfected by psychologist Yves Clot. She seeks to capture the multiple discourses and perspectives around a particular craft, integrating researcher and workers to facilitate the installation of a dialectical movement of analysis and production of knowledge about the work, ownership of these knowledge workers and the collective transformation of labor activity. We chose a qualitative approach and the realization of documental analysis of the abstracts of researches that resulted in the production of doctoral theses and dissertations held in Brazil between 1987 and 2011. Were examined studies that had their abstracts gathered and made available by the Coordenadoria de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) on its website. The results show that self-confrontation is used piecemeal studies produced in the area of Education, used primarily to collect data and to give less emphasis to the transformation of the labor process.

Estudo exploratório sobre a delimitação e práticas contemporâneas da educação não formal

This paper presents the survey, demarcation and discussion of different forms of education, which are education unintentional or intentional informal education, which unfolds in formal and non-formal education. The study of the proposed theme was carried through the review, critical analysis and synthesis of academic and scientific literature relevant to different forms of education. It approaches so prominent non-formal education, due to the significant rise of the practices related to it and increase the visibility of the professionals who took teaching as craft specifically in this educational modality. The main sub-areas of non-formal education presented in the article are: corporate education, non-formal education in social held on nongovernmental organizations (NGOs), non-formal education aimed at prevention and health promotion, formation of free courses to people in different areas of knowledge and practice. At the end, pointing to the importance of considering the non-formal education records within its ambit the existence of political and pedagogical rationales different, even opposite, which requires teachers and researchers in the educational field constant vigilance epistemological, so to contribute to the construction and consolidation of a critical education, creative and emancipatory.

Estudo de propriedades da resina acrílica termoativada por energia de micro-ondas frente às variações nos procedimentos de inclusão

On heat cured acrylic resins by microwaves energy the action of electromagnetic waves on methylmethacrylate promote the polymerization process. However, part of this energy is absorbed by the gypsum present in the flask and the function of this gypsum is to maintain the characteristics of specimen, nevertheless is unknown in the literature as the amount of water present in this gypsum affects the characteristics of acrylic resin. The proposal of this study was verified if dried gypsum influenced in some properties of the acrylic resins thermally activated by microwaves: presence of porosity, microhardness, roughness, flexural strength and dimensional change. Two different types of acrylic resin for complete denture were utilized: Lucitone 550 e Vipi-Wave and groups were formed: Lucitone 550, polymerization by microwave energy without gypsum treatment; Lucitone 550, polymerization by microwave energy with pretreatment gypsum; Vipi-Wave by microwave energy without gypsum treatment; Vipi Wave, polymerization by microwave energy with pretreatment gypsum; Lucitone 550 control group polymerization in hot water bath. For both situations were performed analysis of microhardness and porosity three different metallic shaped specimens were formed with followed dimensions: 2,0x2,0x2,0cm (8cm3); 2,0x2,0x1,0 (4cm3) e 2,0x2,0x0,5 (2cm3). Standardized wax specimens was used to prepare groups (n=9) and included in glass fiber flasks. The gypsum dry was made by microwave oven cycle (10min and 600W) and then the flasks were maintained in dry oven during two hours. Polymerizations of specimens were made and then polished. Wax patterns #7 obtained from the metal were embedded in plastic flask and following the processes of pressing and polymerization of the resin according to established groups. To evaluate the flexural strength, specimens 65mm x 10mm x 3.0mm from metallic patterns in bar format were made. ...

Analysis of anticaries potential of pit and fissures sealants containing amorphous calcium phosphate using synchrotron microtomography

The aim of this study was to analyze the anticaries potential of pit and fissure sealants containing amorphous calcium phosphate (ACP) by synchrotron microtomography. Bovine enamel blocks (4x4 mm; n=50) were selected through surface hardness (Knoop) analysis. Slabs were obtained through cross-sections taken 1 mm from the border of the enamel. Five indentations, spaced 100 mu m apart, were made 300 mu m from the border. Ten specimens were prepared for each tested material (Ultraseal XT plus TM, Aegis, Embrace, Vitremer and Experimental Sealant). The materials were randomly attached to the sectioned surfaces of the enamel blocks and fixed with sticky wax. The specimens were submitted to pH cycling. After that, the surface hardness (SH1) was determined, and the blocks were submitted to synchrotron microcomputed tomography analysis to calculate the mineral concentration (Delta g(HAp) cm(-3)) at different areas of the enamel. The comparison between the SH1 and DgHAp cm(-3) showed a correlation for all groups (r=0.840; p<0.001). The fluoride groups presented positive values of DgHAp cm(-3), indicating a mineral gain that was observed mainly in the outer part of the enamel. The ACP showed mineral loss in the outer enamel compared with fluoride groups, although it inhibited the demineralization in the deeper areas of enamel. The combination of two remineralizing agents (fluoride and ACP) was highly effective in preventing demineralization.

Glycaspis brimblecombei Moore, 1964 (Hemiptera: Psyllidae) on eucalyptus: oviposition non-preference and antibiosis

Forest plantations with Eucalyptus spp. (L'H,r) in Brazil are highly yielding. However, this activity is more and more threatened due to interactions with phytophagous insects, especially by exotic species, such as the red gum lerp psyllid Glycaspis brimblecombei Moore (Hemiptera: Psyllidae). This study aimed to evaluate the resistance in eucalyptus against the psyllid in oviposition and biological development assays, attempting to identify potential genotypes resistant to the pest for forest plantations. In addition, we tested the hypothesis of that concentration of total phenolics and lignin, and amount of epicuticular wax were associated with the expression of resistance. Results showed that there was variation in the levels of resistance among the genotypes assessed. Oviposition non-preference was observed on Eucalyptus citriodora (Hook) in free-choice and no-choice tests, and Clone FP10 was least preferred in the no-choice test. The genotypes E. citriodora and Clone FP6 provided 100 % nymphal mortality, and Clones FP7 and FP9 also affected negatively the G. brimblecombei development by lengthening the duration of the nymphal stage and reducing adult emergence. Clone FP6 had higher concentration of total phenolics and larger contact angle formed between the water droplet and leaf surface, which may be associated with thicker layer of epicuticular wax on the leaves, and one of the causes of high nymphal mortality. Thus, the use of the resistant genotypes of eucalyptus screened against G. brimblecombei is a promising and viable alternative for forest plantations infested with this pest.
