Educação e economia solidária: contribuições da pedagogia da alternância para a formação dos catadores de materiais recicláveis

This text presents the Pedagogy of Alternating methodology, highlighting its contribution to re-think the formation of catadores of recycling materials (rubbish collectors). Whereas the use of this approach in the urban area is unusual, the goal of the article is to initiate a debate to promote further elaborations. Initially an overview of the Pedagogy of Alternating is presented and the main instruments used in this approach are commented. Two theoretical and methodological issues are indicated as challenges for catadores formation: the relations between Education and Work and the relations between Theory and Practice. The need to overcome dichotomy between these dimensions of human activity (that predominates in today's society) is defended. The catadores work reveals the exclusion of these workers of less organized sectors of production chains, with few opportunities to obtain better income and qualification. Overcome this gap requires an intense training to turn the catadores in recycling workers . To reach this goal the implementation of Alternating experiences between study and work in cooperatives and schools is not enough. A deep transformation is needed over the ways and subjects of both study and work, in order to create emancipating activities that promotes a full development of these workers.

Proposição de modelo de logística reversa de resíduos sólidos domésticos recicláveis para o municípios de Rio Claro - SP

The approval of the Solid Waste National Policy on August 2, 2010, brought important advances on the issue of solid waste nationwide. Several requirements were imposed causing public and private sectors to direct the problem more diligently. At the same time, the growth of human consumption and the negative impacts of related activities are increasing pressure for new ways to manage wastes. This study was carried out in order to bring proposals for a new model of solid waste management in the city of Rio Claro. To do so, it was used methodologies which stick to collaborative approaches in order to co-create a new vision considering different points of view . This new proposal includes four main initiatives: the integration of a reverse logistics system and collection of recycling materials in all kinds of educational institutions; the use of a routing platform for collection of solid wastes and recycling materials; the application of a garbage fee to residents who use the collection of solid waste system; and a bonus system developed by the private sector as a marketing strategy, encouraged by the public sector, enabling residents to separate their wastes correctly and leave them in one of the educational institutions to exchange points for discounts at local markets

Avaliação clínica da efetividade do clareamento de consultório sem troca do gel clareador

Esse trabalho teve como objetivo avaliar, clinicamente, a efetividade de dois agentes clareadores aplicados sobre a superfície dentária durante 45 minutos, sem troca do gel. Foram selecionados 10 pacientes de acordo com os critérios de inclusão e exclusão, e a arcada superior dos pacientes foi dividida em duas hemiarcadas (n = 10): na hemiarcada direita (HD), foi aplicado o peróxido de hidrogênio a 35% (PH) Clàriant Office (Angelus); e, na hemiarcada esquerda (HE), o PH 38% Opalescence Boost (Ultradent). Foram realizadas duas sessões clínicas, de 45 minutos cada, com intervalo de uma semana entre as sessões. Inicialmente, ao tratamento clareador, os pacientes receberam profilaxia, moldagem para guia de mensuração de cor com silicone de condensação e avaliação de cor por meio de um aparelho espectrofotômetro Vita Easyshade (Vita Zhanfabrik, Alemanha). Após 14 dias do término do tratamento clareador, foi realizada a mensuração final da cor dos dentes. Os dados foram submetidos ao teste t e de Tukey (p < 0,05). Os resultados demonstraram não haver diferença estatisticamente significativa entre as hemiarcadas quanto à efetividade do clareamento (p = 0,146) e nem quanto à sensibilidade. Pode-se concluir que a aplicação dos materiais avaliados sem troca do gel, por 45 minutos, foi eficaz em promover o clareamento de dentes vitais e com baixa sensibilidade dentária.

Emprego de carvão ativado e resinas de troca ionica na remoção de substâncias orgânicas contaminantes do alcool etílico

This work had with objective to characterize and evaluate the performance of the combined system, involving activated charcoal and ionic exchange resins in the removal of substances organic contaminating of the ethyl alcohol from the fermentation of the cassava starch. To testing was used ethyl alcohol PA 96 oGL, conductivity of 0.90 μS/cm at 25 oC, acidity of 60 mg/L and Barbet test of 43 minutes at 15 oC. The contaminated alcohol was composed of ethyl alcohol additive of higher alcohols, organic acids, ester, diol, aldehydes, ketone and ether. Contaminated alcohol was added 2% activated charcoal and after the adsorption isotherm in ionic exchange resins was tested. The adsorption with activated charcoal was performed in a Water Bath at 30 oC for one hour and a half and shaking. Already adsorption ionic exchange columns occurred at room temperature on columns of 93,4 cm in filling height and diameter of 2.29 cm, for flows of 180 mL/min and 90 mL/min. Samples were collected in the tests with charcoal and with each one of the resins and the following analyses were performed: conductivity, acidity and Barbet test. The medium values for conductivity, acidity and Barbet test after the adsorption in charcoal and cation and anion resins were respectively: conductivity was 240; 354 and 465 μS/cm to 25 oC; acidity of 1.081; 1.103 and 1.062 mg/L and the Barbet test was 21; 20 and 9 minutes to 15 oC. It was observed that the addition of 2% of activated charcoal and the permanence in the columns of adsorption was not sufficient to remove the organic substances contaminating of the ethyl alcohol.

Conformidade ergonômica dos controles no posto de trabalho do operador de trator: estudo de caso NH 7630

This article discusses an ergonomic analysis of the controls used by tractor operators, covering their positions in relation to the casing of your job. Was performed an assessment of the controls of the job of a model NH 7630 tractor average power of 74 kW (100 CV), using the norms of the ABNT. With this screening could detect the positive and negative. Then was accomplished an analytical study of the controls. Evaluation results show that some controls of tractors have errors evaluated in relation to NBR/ ISO 6682.

Comparativo ergonômico de duas metododologias para aquisição de coordenadas tridimensionais do posto de trabalho do operador de trato

This research aimed to the comparison between two methods for obtaining three-dimensional coordinates of the controls of the upper limbs of the job of the tractor operator. The methods used were based on NBR / NM / ISO 5353 - Road machines, tractors and agricultural and forestry machinery – Reference point of the seat. The first method used follows the principles recommended by the standard NBR/NM/ISO/5353 The second method is an adaptation of this standard with the introduction of a laser measuring equipment developed by Silva (2009). The results were compared statistically to evaluate differences between the methodological processes involved. In this research, data was collected thought a brand new tractor Massey Ferguson model MF 292, awarded by the dealership from Londrina. The results have shown a considerable variation between the traditional measurement process and the laser measuring. It must be considered that this variation can be used to calibrate the tractor controls positioning, therefore the tractor is not in accordance to ABNT.

Laboratório de design solidário - LABSOL: projeto de extensão em design na perspectiva da geração de trabalho e renda

Introdução: Na sociedade contemporânea costuma-se associar Design ao consumo de luxo, entretanto o design encontra-se aplicado a todos os objetos, do automóvel ao clips, todavia o Design parece estar sempre atrelado à sociedade de consumo, à indústria a serviço do capital e das relações de subordinação e expropriação a ele atrelado. Assim faz-se necessário despertar no aluno do curso de Design a possibilidade da aplicação de seu conhecimento a serviço de uma sociedade mais democrática e solidária, de não apenas produzir a serviço do capital, mas pensar de forma mais abrangente, considerando o bem comum. Objetivos: O Labsol, desde 2007, procura: Otimizar, revitalizar e qualificar a produção artesanal através dos conceitos de ecodesign, sustentabilidade e economia solidária, tendo em vista a auto sustentabilidade das comunidades produtoras. Desenvolver projetos e ações que promovam encontros entre o Design e o patrimônio cultural do artesanato. Preocupar-se com a qualificação do produto artesanal e sua inserção no mercado, tendo em vista a auto sustentabilidade das comunidades produtoras. Métodos: A formação dos integrantes do LabSol é continua e baseada em três conceitos fundamentais: sustentabilidade, economia solidária e eco design. As ações se dão a partir do convite de uma comunidade de artesãos na perspectiva da qualificação estética ou produtiva de seus trabalhos e a melhoria da geração de renda. Utiliza-se o método empírico, de caráter prático, através de estudo de caso. Em uma visita aprende-se métodos e técnicas utilizados pela comunidade, e de volta à sede, faz-se revisão bibliográfica e utiliza-se a metodologia do projeto em design para melhoria das técnicas produção, o redesenho de produtos e a geração de novos objetos de design. Construídos modelos e protótipos e avaliado seu potencial de comercialização são submetidos a aprovação da comuni-dade através de oficinas. O diferencial no trabalho do LabSol se dá na maneira que os projetos são entregues aos grupos. Entende-se todo o processo como um aprendizado de mão dupla, da troca de saberes, onde os membros do laboratório aprendem da comunidade dados de sua cultura e de seus modos de fazer, em contrapartida novos produtos são levados de volta a comunidade, entendidos como mais um dado cultural posto a disposição da comunidade podendo ou não ser por ela incorporado. Resultados: Com mais de 20 grupos atendidos, e centenas de produtos de eco design, as ações o LabSol resultam na pesquisa de eco design, materiais, técnicas, métodos e de novas tecnologias sociais, gerando um número significativo de publicações e exposições de divulgação. Tem recebido graduandos de relações públicas e engenharia de produção, a junção de saberes tem permitido um aprimoramento na qualidade de atendimento ás comunidades.
