    Electric shocks fatalities are common globally, and so the number of annual worldwide electrical fatalities needs to be reduced. Electrical fatalities are caused by contact with a live-wire. Contact with 35 and 50 V live-wires can be harmful, and accidents can take place when an insulating safeguard is not used, especially in high voltage power applications where the insulating safeguards are heavy. Hence, a safeguard for preventing shocks during such applications needs to be developed. However, safeguards that are easy to handle are not often developed because it is difficult to evaluate the function of such safeguards. Thus, we need to develop a safeguard that can be easily handled in narrow space. In this study, we investigate a design for safeguards that have a capability of easy handling in the space. The safeguards are studied based on the results of the measured AC breakdown voltage. In the experiments, we measure the AC breakdown voltage for the single and double layers of an EVA sheet and a PMMA plate. The insulating materials of the EVA sheet and PMMA plate are used for designing the insulating safeguard. The results prove that the experimental formulae can be used for designing the safeguards that are used for AC live-wires, which consist of two insulating materials.

    The purpose of the present study was to clarify the current status of psychiatric services and return to work programs within occupational mental health services provided by psychiatric hospitals and clinics in Osaka prefecture. The study focused on whether employment of occupational health physicians and psychological specialists was associated with providing of occupational mental health services. A self-administered questionnaire was mailed to 470 psychiatric hospitals and clinics in Osaka prefecture in 2013. A total of 215 organizations responded (response rate=45.7%). In the psychiatric organizations studied, 46.5% of clinical psychologists and 34.0% of psychiatric social workers who were employed as psychological specialists. Psychiatric medical organization reporting the employment of occupational health physicians was 48.4%. Organizations providing return to work programs was 19.5%; of those that did not provide such programs, 17.7% reported that they would do so in the future. The employment of occupational health physicians increased the percentages of providing of return to work programs. The employment of psychological specialists increased the percentages of psychological counseling services and return to work programs. To provisions of counselling and return to work programs, the employment of occupational health physicians and psychological specialists may be important factors.
