The effects and roles of social support and stressors (stressful life events and chronic strains) on psychosocial distress were examined in a model with data from a sample of the white-collar workers (N = 416) in Korea. The findings of this study present that mean levels of psychosocial distress were higher' in the female, youth, unmarried and divorced, and low economic status (monthly income). The analysis also shows that, as expected, stressful life and chronic strains as stressors are positively related to occurrence of psychosocial distress, and social support is negatively related to psychosocial distress. Further, the contribution of social support to predicting psychosocial distress is greater in magnitude than that of stressful events, chronic strains, and sociodemographic variables. There is no evidence that social support buffers the impacts of stressors on psychosocial distress, rather social support takes a role of main or direct effects on psychosocial distress. Therefore, the strength of the social support is an important and meaningful strategy to prevent from stress and mental, physical illness.

The effects of multiple exposures to pesticides on plasma cholinesterase(ChE) activities and urinary p-nitrophenol excretion were evaluated in rats. Rats were received single dose i.p. with LD50/100(mg/kg) of organophosphorous(OP), organophosphorous-organochroline(OP-OC), organophosphorous-carbamate(OP-CAB), organophosphorous-organoarsenate(OP-OA) pesticides for 4 consecutive days. In repeated administration of pesticides, plasma ChE activities were decreased, but urinary p-nitrophenol were increased after the first injection and then decreased gradually. The recovery rates of ChE activities and p-nitrophenol excretion at 48 hours after the fourth infection were delayed in comparison with the baseline value of 24 hours before the first injection. Statistical significances were found between OP and other groups except OP-OA group after the second injection in plasma ChE activities, but in urinary p-nitrophenol excretion there was statistical significance only between OP and OP-CAB.

The coronary artery fistula from right coronary artery to left ventricle is a rare disease among coronary artery anomaly. We experienced three cases of rare coronary fistula and report with literature review. Although symptoms of coronary artery fistula are associated with arteriovenous shunt and coronary steal phenomenon, many cases are asymptomatic. In this report, all patients had no symptom. but incidental murmur was noted (two are continuous, one is diastolic rumbling). The diagnosis was made by transthoracic or transesophageal echocardiogram and selective coronary angiography. Because patients were relatively young and the diameter of dilated coronary artery were huge, we perfomed operation on three patients.

This study was conducted to understand health status by general characteristic, and to find out relationship between social support and worker's health status. Health status was measured using SF-36(Medical Outcome Study Short Form 36), a 36 item self administered Instrument. The finding of this study were as follow; Mean scores of health status by sex were higher in male. The younger worker reported good health on physical functioning and role limitation-physical than did the older worker, but the older worker reported good health on social functioning and mental health. Mean scores of health status were higher in high income and white worker. When the relationship between social support and health status, social functioning, role limitation-emotion, mental health, vitality, general health were significantly related. Therefore we reviewed the evidence that socio-economic condition are associated with health status in this study, and that the strength of the social support was a important to maintain health.
