The study aimed to estimate the economic valuation of statistical life (VSL) in mortality risk of heat wave due to climate change. The double-bounded dichotomous choice (DBDC) of contingent valuation method was used to estimate the willingness to pay (WTP) with 801 adult respondents aged 30 to 75 residing in Seoul. We modified DBDC with adopting spike model to deal with genuine zero willingness to pay. Monthly mean WTP was 18,210 KRW, and monthly mean WTP adjusted by income was 18,488 KRW. Based on the monthly mean WTP, VSL was estimated to 369.8 million KRW (95% CI 325.1 million KRW c- 414.4 million KRW). Our results showed that more serious perception regarding the risk of climate change, the higher WTP to reduce risk of heat wave, and in addition, the seriousness was related with respondent perception that threat would be happen to be real. These patterns of WTP showed similar trend regardless of vulnerable or non-vulnerable groups. The study findings suggested that policy adaptation and alternatives of heat wave should include non-vulnerable population as well as vulnerable population on which the adaption policy of heat wave was mainly focused.

Objectives: The objective of study was to calculate the municipal level environmental burden of disease (EBD) due to heat wave. Methods: The data used were Korea National Health Insurance 2011 claim data and 2011 death registry. Heatwave related diseases included hypertensive heart diseases, ischemic heart diseases, cerebrovascular disease, and heat related illness. According to the method that WHO proposed, the study computed population-attributable fraction with relative risk which come from previous study and proportion of exposure which the study calculated with historical meteorology data. Results: The Average of 251 municipal EBD was 2.11 per thousand persons. The value of years lost due to disability was 11 times higher than that of years of life lost. On average EBD of county and southern geographical areas tended to be higher than those of District or city areas. The relationship between municipal deprivation index (composite deprivation index) and EBD showed the positive association, which means that the worse deprived municipal is, the higher EBD takes. Conclusions: Climate change is getting one of the major risk factors of cardio-cerebrovascular disease, which is the second leading cause of death. The study results suggested the urgent policy planning and reaction of climate change adaptation.

Objectives: The purpose of this study was to investigate the effects of muscle strength exercise on physical function and quality of life in the frail elderly. Methods: Subjects were 401 frail elderly people selected by the screening tool developed by Japan department of Health, Labor and welfare. The program was carried out for twice a week for 12 weeks. Data were analyzed with paired t-test and t-test using STATA program. Results: 1) Muscle strength exercise for the frail elderly showed statistically significant effects on improving grip strength, single leg stand, TUG(Time up to go) and quality of life. 2) The grip strength and single leg stand indicators showed statistically significant effects between the over 75 years old and the under 75 years old. However, TUG and quality of life indicators didn't show statistically significant effects between the over 75 years old and the under 75 years old. Conclusions: The muscle strength exercise for the frail elderly people was very effective on improving grip strength, single leg stand, TUG and quality of life and especially, it was more effective in the over 75 years old than in the under 75 years old.

The purpose of this study is to estimate the amount of willingness to pay (WTP) for adaptation policy to reduce the health damage attributable to cold waves using contingent valuation method (CVM). The survey was conducted on 1,500 adult males and females aged from 30 to 75 years old in Wonju, Ganwon Province, Yeoncheon-gun, Gyeonggi-do, Seoul, Geoje, Gyeongsangnam-do, Namhae, Gyeongsangnam-do, Gwangju from January 23, 2015 to February 13, 2015. In order to solve the problem of treating nonpayment amount, which is common in CVM, we applied the mixed model and estimated the payment amount by the Bayesian method assuming the Weibull distribution. As a result, the average WTP for adaptation policy to prevent the health damage caused by cold waves was 8,492 won per household per year and the median price was 363 won per household. There was a positive relationship between the respondents living in the cold wave areas, the subjective thoughts on the frequency of the cold waves, sex, age, education level and income level of the households. The study of cold wave is insufficient compared to the study of heat wave. Future research should be conducted on health impacts, social burdens of the cold waves and risk based adaptation policies.

Objectives: This study aimed to examine how the relationship between socioeconomic factors at the macro level and suicide mortality rate of Korea was different from that of other OECD countries. Methods: We created OECD panel data of 29 OECD countries from 1985 to 2006 and analyzed the relationship between socioeconomic factors and suicide mortality rate for separate age and sex groups using a fixed-effect model. Economic factors included per capita GDP, per capita GDP growth rate, unemployment rate, and womens economic participation rate. Social factors included birth rate, alcohol consumption, and the percentage of population 65 and older. Results: Unemployment rate had a positive relationship with suicide in other countries but it had a negative relationship in some groups of Korea. Womens economic participation rate was both positively and negatively related with suicide in Korea but it did not relate to suicide in others. The negative relationship of birth rate and the positive relationship of alcohol consumption with suicide were evident in Korea, which were not found in other countries. The percentage of population 65 and older was negatively correlated in some female groups in Korea, while no significant relationship was found in other countries. Conclusions: Korea was substantially different from other OECD countries in the relationship between socioeconomic factors and suicide mortality rate.

There is enormous public interest in measuring the impacts of climate change. Food borne diseases may be one of the most significant contemporary public health problems. The purpose of this study was to estimate the prevalence of food borne diseases due to the climate change and to predict their future impact. The analytical approach used generalized linear Poisson regression models adapted for timeseries data. To account for seasonal patterns of food-borne disease not directly due to weather factors, Fourier terms with annual periodicity were introduced into the model. To allow autocorrelation due to biological process of pathogen development and host reaction and the longterm trend, we considered time lags and year variable. The data we used was a panel data for the years between 2003 and 2007. The food-borne disease patients increased 5.27~5.99%(relative risk rate) per a Celsius degree. Moreover, the weekly food-borne disease patients increased 6.18~7.01%(relative risk rate) per a Celsius degree. In the case of the weekly patients, the relative humidity was significant, so the weekly patient decreased 1.7% when the relative humidity increased 1%. Compared to reference year, 2003, there was no a certain trend in the food borne disease patients due to differences as per year and analysis methods. Climate change will not result in a uniform warming over the globe. With the oceanic and atmospheric circulations, large scale change will adjust smaller scale weather features including the frequency of extreme events, and in turn the prevalence of food-borne diseases. Disease surveillance, proper case management, environmental monitoring and international communication systems were the keys for curbing the spread of contamination and the outbreak of food-borne diseases.
