In the industrial accident that occurred in the recent contract type of business or establishment (including subcontractor) employers and contractors who demand among employers, would be liable to have a proper discussion on how to prevent industrial accidents. To resolve this issue, it introduced the discussion with the Japanese legal system, which has a system similar to the Occupational Safety and seeks to help us in our country's future institutional improvements.

This study was carried out to screen high α-glucosidase inhibitor (AGI) activity pepper lines from EMS treated mutants of pepper. The optimal concentration of EMS for inducing mutants to pepper was 0.15M and the optimal treatment time of EMS was 2 hours. With this condition, many mutants which have high AGI activity were screened and especially leaf of two lines were showed 27 times inhibitory activity on α-glucosidase comparing with control. There is no difference between mutants and nornmal plant in growth. These results indicated that AGI activity of pepper leaf would be increased by mutation.
