According to the epidemiological studies in chromium workers, hexavalent chromium is associated with the risk of lung cancer. Reactive oxygen species produced by hexavalent chromium exposure may play an important role in the carcinogenesis process. We measured one kind of oxidative DNA damages, 8-hydroxydeoxyguanosine (8-OHdG) and its repair activities as an indicators of cellular oxidative stress in rat lungs by the repeated inhalation exposure to sodium chromate.(omitted)

This study proposes to suggest a direction hereafter which is the most suitable operating system of electrical safety management agency for electrical facilities to enhance electrical safety considering our domestic conditions. It was designed to prevent electrical disasters which are increasing due to environmental changes in the electrical industry, and the diversification and complication of the electrical facilities. And the strategy of this research is based on conditions of safety management agency for the electrical facilities, with the analysis on conditions of electrical disasters, and with a questionnaire investigation for owner of electrical facilities, safety management agency. Results of this research are expected to be used to prevent electric fires and shocks effectively by reinforcing the electrical safety management agency of electrical facilities having danger of large-scaled accidents. It is expected to enhance the nation's competing power against foreign countries by reducing the human and physical loss, resulted from the development of reasonable operating system for electrical safety management agency.
