The loss of nitrogen and phosphorus from sediments in two watersheds, one naturally regenerating and one artificially planted, in Sacheon-myun, Gangneung-si, Gangwon Province, were measured two years after a forest fire in 2000. Sediment losses occurred five times in the course of the year. In the artificially planted watershed, $50{\sim}140$ times more nitrogen and $54{\sim}139$ times more phosphorus were lost with sediments during heavy rains, from July to August, than in the naturally regenerating watershed. When the typhoon Rusa struck the country, 1,389 times more nitrogen and 1,647 times more phosphorus were lost from the artificial watershed. In spite of the limited scope of this study, these results suggest that artificially planted watersheds are extremely vulnerable to catastrophic natural disasters such as typhoons. Elevated loss of nutrients in the artificially planted watershed might have resulted from the mechanized silvicultural practices employed immediately after the fire. To maximize soil preservation, the timing and necessity of plantation practices should be reconsidered, and rapidly regenerating vegetation should be protected to promote nutrient uptake and to mitigate nutrient loss from burned forests.

Cigarette smoking has been identified as the most important source of preventable morbidity and premature mortality (WHO, 1995), The prevalence of smoking among men is very high in Korea. This study estimated productivity losses due to smoking in Korea, 1997. The derivation of cost estimates for mortality, disability, hospitalization and use of physician services related to cigarette smoking is bas 어 on the calculation of attributable fractions suggested by MacMahon and Cole and Smoking-Attributable Mortality, Morbidity, and Economic Cost(SAMMEC) software. To estimate the number of deaths from neoplastic, cardiovascular, respiratory diseases associated with cigarette smoking, estimates for adults(aged 20 years and over) were based on 1997 mortality data, 1995 data on smoking prevalence from Korea Institute for Health and Social Affairs. Smoking-attributable indirect morbidity cost data were obtained from the National Federation of Medical Insurance. As the result of cost estimation, these productivity losses were 336-430 billion won. During 1997, 8,620-10,804 deaths were attributed to smoking. Cigarette smoking resulted in 133,991-169,422 Years of Potential Life Lost (YPLL) to life expectancy. For smoking -attributable indirect mortality costs, the present value of future earnings(PVFE) for the age at death are 299-384 billion won. Smoking-attributable indirect morbidity costs, the costs of lost productivity for persons who are disabled by smoking-related chronic diseases are 37-46 billion won. In this study the productivity losses due to smoking were restricted to the health effects of smoking. It is possible that these costs were underestimated with the limitation of the data. Smoking is the leading preventable cause of illness and death. The results of this study can be used as elementary data for antismoking policy.

The aim of this study is to analyze the mortality and potential years of life lost (PYLL) by malignant neoplasm of lung between OECD countries and Korea. Based on the result, we tried to point out a problem on mortality caused malignant neoplasm of lung to make the best strategy for policy and education on public health. Using the ANOVA analysis between Korean and OECD countries, the lung cancer-induced mortality and PYLL in total and gender-specific Korean population were greater after 21th century than before. In particular, the PYLL was sharply elevated than the mortality. Taken together, the present study indicated that the lung cancer-induced PYLL between Korean and OECD countries can be more important parameter.

This present study is designed to analyze the mortality and potential years of life lost (PYLL) by malignant neoplasm of lung between OECD countries and Korea before and after the year 2000. We used the methods of Wilcoxon Singed Ranks Test between korean and other 30 OECD countries between 1993-1999 and 2000-2006 year using 2009 OECD Health data(2010) of 30 contries. At the results, the mortality of lung cancer in male korean was significantly increased after 2000 year whereas those in other 23 countries decreased. The mortalities in female were increased in 20 countries including Korea. PYLL in male and female korean were significantly decreased and male PYLL in other 26 countries was decreased, but female PYLL in other countries showed various patterns; increase in 12 countries and decrease in 3 countries. Therefore, the present study elucidated that the lung cancer-induced PYLL in the comparison between korean and OECD countries can be more important parameter.
