This article aimed to select items with which to evaluate the ergonomic and safety conditions in tractors used by smallholders and family farmers, based on standardization research and legislation for the sector. Brazil has a comprehensive set of technical standards and legislation for the agricultural machinery sector intended to guarantee product standardization and to promote the health and safety of the users. Therefore, the initial step of this research was to review the technical norms and legislation for the product in order to develop instruments to assess their ergonomic and safety conditions. Twenty-eight Brazilian Technical Standards (NBR) and four Regulatory Norms (NRs) were investigated, in addition to CONTRAN (the Brazilian Traffic Council) Resolution No. 227/2007, which establishes requirements for vehicle lighting and signaling systems, generating 57 safety evaluation items and 35 ergonomic items. These evaluating items were applied to six tractor models commonly sold to smallholders with a rated engine power of 37-57kW. The results indicate levels of safety unconformities as high as 39.7% for the worst case and 44.7% ergonomic-related problems for the same tractor model. These data point to the need for improvements, especially in lower power tractors.
RESUMOO objetivo desse trabalho é desenvolver um aplicativo pedagógico como tecnologia de informação e comunicação móvel com acesso à Internet, a fim de auxiliar a disciplina de Desenho Técnico nas escolas da rede pública. O projeto foi executado pelas alunas da especialização em Ciências e Tecnologias na Educação do Instituto Federal Sul-rio-grandense, nos meses de junho e julho de 2016, como parte da disciplina de Informática para Educadores.Para desenvolver o aplicativo, utilizou-se um site gratuito, denominado Appy pie, o qual apresenta uma interface intuitiva para criar novos apps em plataformas como IOS, Android e Windows Mobile. O aplicativo gerado visou tornar-se uma ferramenta de complementariedade do ensino de Desenho Técnico, sendo um facilitador na pesquisa de diferentes tópicos, porém não são todos que se adaptam à nova tecnologia, devido à dicotomia das escolas, gerando um entrave educacional para a realização de testes do aplicativo. Contudo, o software teve boa aceitação pelo corpo docente da Instituição Federal Sul-rio-grandense, podendo ser, futuramente, inserido na grade da disciplina, como assessório de consulta, visto que estimula a pró-atividade do educando em tarefas extra classe.
