OBJECTIVES
To estimate the value of statistical life (VSL) and health damage cost on theoretical mortality estimates due to environmental pollution. METHODS: We assessed the health risk on three environmental problems and eight sub-problems. Willingness to pay (WTP) was elucidated from a questionnaire survey with dichotomous contingent valuation method and VSL (which is the division of WTP by the change of risk reduction) calculated from WTP. Damage costs were estimated by multiplying VSL by the theoretical mortality estimates. RESULTS: VSLs from death caused by air pollution, indoor air pollution and drinking water contamination were about 0.3, 0.5 and 0.3 billion won, respectively. Damage costs of particulate matters (PM10) and radon were higher in the sub-problems and were above 100 billion won. Because damage cost depends on theoretical mortality estimate and WTP, its uncertainty is reduced in the estimating process. CONCLUSION: Health damage cost or risk benefit should be considered as one scientific criterion for decision making in environmental policy.

AbstractAbstract PDF
1,281 male subjects who had been examined more than 3 times for regular check-up in one human dock center of the university hospital were studied between 1990-1995, to evaluate the effect of health counseling with life style and gamma-GTP value between 1054 normal group without intervention and 227 abnormal group with intervention, ages from 30 to 69 years old. Total mean value of gamma-GTP was 45.7+/-40.7 unit with highest gamma-GTP value in age group 50-59 on initial examination. Total abnormal rate was 17.7% with the highest abnormal rate of 18.6% in age group 50-59. Initially, the value of gamma-GTP was significantly different according to the degree of alcohol intake, relative weight and smoking in normal group(p<0.01) not in abnormal group. In conclusion, the value of gamma-GTP were significantly increasing in normal group without intervention and significantly decreasing in abnormal group with intervention(p<0.05), which suggests the effect of health counseling, such as the recommendation to change the health behaviour.

AbstractAbstract PDF
This is to analyze and compare the distribution of the liver function test and its abnormal rates of the preemployment screening for office workers in asymptomatic young age groups between female and male. Liver function test(SGPT and SGOT) of 8,184 young adults(2,633 in female and 5,551 in male) were examined during the period from Jan.1,1994 to Dec. 31, 1994. The results were as follows; 1. Mean level of SGPT was 9.l+/-7.6(IU/L) in female, 21.0+/-27.9(IU/L) in male, and that of SGOT was 15.1+/-6.0(IU/L) in female, 20.5+/-26.5(IU/L) in male. There were significant differences(p<0.01) between female and male in both SPT and SGOT. And also there was significant increasing trend(p<0.05) by age groups in male for SGPT, decreasing trend(p<0.01) in female for SGOT. 2. In the abnormal rates of liver function test by the level of cut-off value, there were significant differences up to twice between the lowest and the highest cut-off value in both female(0.4% vs 0.7%) and male(6.5% vs 12.4%) 3. Abnormal rate of SGPT was 0.4% in female and 6.3% in male, and that of SGOT was 0.2% in female and 1.2% in male with significant differences between female and male in both tests.
