Com o aumento do consumo de bens e serviços, os riscos ocupacionais enfrentados pelos colaboradores em suas funções laborais aumentaram, tornando-os mais suscetíveis a doenças ocupacionais, acidentes de trabalho e outros prejuízos associados à falta de treinamento adequado. O objetivo deste artigo é mostrar a importância do treinamento e desenvolvimento na saúde e segurança no trabalho. Os resultados indicam o quão é valioso para a empresa a aplicação de programas de T&D, pois eles trazem benefícios ao empregador e ao empregado, como: diminuição de processos trabalhistas, diminuição de acidentes, aumento da produtividade, redução do absentismo e turnover, e melhora a qualidade de vida do colaborador. No entanto, conclui-se que as empresas, de modo geral, ainda carecem de treinamentos efetivos de saúde e segurança do trabalho, em que pese sua importância para o bem-estar do trabalhador.

In studies to identify genotypes resistant to infection with citrus viroids, Eremocitrus glauca and Microcitrus australis were selected because their evolution in their habitat in Australia and New Guinea may have led to the selection of unusual traits. The movement and accumulation of Citrus exocortis viroid (CEVd), Hop stunt viroid , Citrus bent leaf viroid , Citrus dwarfing viroid , Citrus bark cracking viroid and Citrus viroid V (CVd‐V) in self‐rooted as well as in graft‐ propagated E. glauca and M. australis plants was assessed by northern hybridization, RT‐PCR and by topworking to the sensitive selection 861‐S1 of Etrog citron. In both plant species the inoculated viroids were undetectable unless these plants were grafted to a susceptible Citrus partner, the rough lemon rootstock and/or the topworked Etrog citron, which acted as viroid sources. The results obtained indicate that M. australis and in particular E. glauca are poor viroid hosts in which viroid replication/accumulation does not occur or is extremely inefficient. However, viroid downward and upward movement to grafted Citrus partners in which viroid replication and accumulation occurs efficiently was not impaired. Eremocitrus glauca and M. australis showed differences regarding their properties as viroid hosts, but for both species CEVd seemed to have the lowest affinity among the viroid species tested and CVd‐V the highest. Even though E. glauca and M. australis do not appear to be truly resistant to viroid infection, they are interesting genotypes for further characterization of the mechanisms involved in viroid infection.
