  • The study is to estimate the social costs of premature deaths due to nuclear power plant(NPP) accidents, by resorting to the contingent valuation method(CVM) which is used to estimate the value of a statistical life(VSL). The VSL estimate is about 3.55 billion won, which is multiplied by some 1.8 million premature deaths due to the accidents in world history of NPP, to get a maximum social cost of 1,952 trillion won. This estimate is equivalent to the 2022 real GDP of Korea. The annual average number of premature deaths and the resulting average social cost is 26,000 and 28 trillion won, respectively. The social cost of premature deaths due not only to accidents, but also the air pollutants from fired power plants(FPP) during 1987~2021 is estimated to be 26,919 trillion won. This is equivalent to 2021 US GDP, and is about 3,000 times higher than that for NPP of 9 trillion won. In 2021, the estimated social costs of FPP and NPP are 1,075 trillion won and 292 billion won, respectively. For South Korea, the study suggests to adapt an energy mix of increased share of electricity production for NPP relative to FPP, given that the 2050 carbon neutrality strategy of Korea is expected to lead to an increased share of renewable energy in electricity production. The study emphasizes accumulating the number of CVM-based VSL studies to ensure efficient energy policies.

  • Although it is mandatory to wear a seat belt that can minimize human injury when traffic accident occurs, the number of traffic accident casualties not wearing seat belts still accounts for a significant proportion.The seat belt wearing detection system for all seats is a system that identifies whether all seat passengers wear a seat belt and encourages their usage, also it can be a useful technical countermeasure. Firstly, this study established the viability of system implementation by assessing the factors influencing the severity of injuries in traffic accidents through the development of an ordered probit model. Analysis results showed that the use of seat belts has statistically significant effects on the severity of traffic accidents, reducing the probability of death or serious injury by 0.054 times in the event of a traffic accident. Secondly, a meta-analysis was conducted based on prior research related to seat belts and injuries in traffic accidents to estimate the expected reduction in accident severity upon the implementation of the system.The analysis of the effect of accident severity reduction revealed that wearing seat belts would lead to a 63.3% decrease in fatal accidents, with the front seats showing a reduction of 75.7% and the rear seats showing a reduction of 58.1% in fatal accidents. Lastly, Using the results of the meta-analysis and traffic accident statistics, the expected decrease in the number of traffic accident casualties with the implementation of the system was derived to analyze the traffic safety effects of the proposed detection system. The analysis demonstrated that with an increase in the adoption rate of the system, the number of casualties in accidents where seat belts were not worn decreased. Specifically, at a system adoption rate of 60%, it is anticipated that the number of fatalities would decrease by more than three times compared to the current scenario. Based on the analysis results, operational strategies for the system were proposed to increase seat belt usage rates and reduce accident severity.

  • The main purpose of this study is to examine the suicide pattern during major holidays which are considered to be in high social integration - New Year's Day, Lunar New Year's Day, Harvest Festival (Chuseok) and Christmas. To confirm suicide patterns, this study hypothesized firstly, the number of suicides would decrease before and on each holiday, and secondly, the number of suicides would increase after each holiday. In detail, this study postulated different patterns by marital status and age groups. Utilizing "Causes of Death Statistics" from 2000 to 2005, the number of suicides by marital status and age group on each day is calculated and categorized by holiday. There are four major findings. First, the decrease in the number of suicides during holiday periods is significant. Second, different suicide patterns by marital status are not found. Third, the difference in suicide patterns by age groups is significant. Specifically, there is a decrease in the number of suicides of the old during Lunar New Year's Day and Harvest Festival (Chuseok). On the other hand, there is no changes in the number of suicides of the young during the same periods. Fourth, a decrease in the number of suicides regardless of marital status and age is found at the end of a year. These results mean that increased social integration is functioned as a "suicide immune system." However, each generation has its own main factor that increases social integration.

  • In this paper, we systematically investigate regional differences of the dead due to injuries in cities, towns and counties about transportation accidents, suicides and fall accidents, which have recently been an important issue of health problems in Korea, The data are from the Annual Report on the Cause of Death Statistics in Korea in 2008. They include the deaths over the age 19 from transportation accidents, suicides and fall accidents with the criterion of the International Statistical Classification of Diseases. Poisson HGLM is applied to estimate the mortality rate under the assumption that the number of deaths follow a Poisson distribution, by considering regions as random effects and by adjusting age, sex and standardized residence tax as fixed effects. Using the results of random effects prediction, the regional differences in cities, counties and towns are marked in disease mapping. The results showed that there were significant regional differences of mortality rates for transportation accidents and suicides, but no significant differences for fall accidents.

  • 본 지역 재정지표와 표준화사망률간의 관계에 대한 것으로, 연구대상지역은 1998년부터 2007년까지의 전국 232개 시 군 구이며 이를 5개 광역권과 4개 도시 종류에 따라 분류하였다. 지역 재정지표는 1인당 지방세부담액과 재정자립도, 재정자주도, 의존재원비율을 활용하였고, 지역 총사망률은1998년에서 2007년까지의 통계청 사망 원자료 상의 사망자수를 분자로, 주민등록인구를 분모로 직접 표준화법을 사용하여 연구대상 지역의 성 연령표준화사망률을 산출하였다. 자료의 분석은 SPSS 12.0K를 이용하여 상관분석, 일원배치분산분석(Tukey b 사후검정) 및 회귀분석을 실시하였다. 주요 결과로는 첫째, 재정지표와 표준화사망률간의 상관분석을 실시하여 연도별로 계수 값을 구한 결과 1인당 지방세부담액을 제외하고 재정자립도, 재정자주도, 의존재원비율 모두 남자, 여자, 전체 모두가 전 연도에 걸쳐 상관계수 값이 통계적으로 유의하였으며, 남자가 여자보다 높은 상관관계를 보였다. 둘째, 재정자립도, 재정자주도 각각을 표준화사망률과 단순 회귀분석을 실시한 결과, 표준화사망률 남자, 여자, 전체가 전 연도에서 통계적으로 유의하였고, 재정자립도와 재정자주도가 낮을수록 사망률이 높은 것으로 나타났다. 셋째, 광역권역, 도시 종류까지 고려한 재정지표의 다중회귀분석을 실시한 결과, 1인당 지방세부담액과 의존재원비율, 광역권역과 도시 종류에 따른 지역을 고려하고도 재정자주도의 효과는 전체사망과 남자, 여자, 전 연도에 걸쳐 모두 통계적으로 매우 유의하여 재정자주도가 높을수록 사망률이 낮은 것으로 나타났고 이런 경향은 여자보다 남자에서 더욱 강하게 나타났다. 넷째, 광역권별 분석의 경우, 충청권은 수도권에 비해서 표준화사망률에서 유의한 차이는 없었으며 호남권과 영남권은 전체 표준화사망률의 경우 전체 연도의 절반 이상에서 수도권에 비해서 통계적으로 유의하게 높았고, 남자와 여자에서는 이런 경향이 약해졌다. 강원 제주권은 전체 사망에서 수도권에 비해 전체 연도의 절반 이상이 유의하게 사망률이 낮았으며, 여자도 이와 비슷한 양상을 보여주었다. 다섯째, 도시 종류에 따른 분석에서 대도시에 비해 중소도시는 통계적으로 유의한 차이는 없었으나, 전 연도에 걸쳐 도농통합도시와 군지역은 대도시에 비해 통계적으로 사망률이 높았다. 여섯째, 전 연도에 걸쳐 의존재원비율이 높아질수록 사망률이 유의하게 높아졌다. 이는 남자, 여자 모두에서 유사하게 나타났다. 마지막으로 연도별 분석 이후 1998년에서 2007년 전체 다중 회귀분석을 실시한 결과 전체 사망과 여자의 경우 1인당 지방세부담액을 제외한 모든 변수에서 통계적으로 유의하였다. 지역의 재정력이 성 연령 표준화사망률에 영향을 미치는 것으로 파악되었는데 이를 단서로 지역의 건강 격차가 발생하는 원인과 기전을 밝히기 위해 향후 보다 면밀한 후속 연구가 이뤄져야 하겠고 지역 간 건강 격차를 완화하기 위한 여러 방법론적 고찰 안에 지역간 재정력의 격차를 완화하려는 정책적인 접근도 필요할 것으로 사료된다.

  • Adult longevity and fecundity of the foxglove aphid, Aulacorthum solani Kaltenbach, were studied at $12.5{\sim}25^{\circ}C$ with $60{\sim}70%$ RH under 16L:8D and the results were put together to build a life table. The longevity of foxglove gradually increased with decreasing temperature below $25^{\circ}C$. Also total fecundity increased with decreasing temperature and highest fecundity was 74.1 nymphs per female at $15^{\circ}C$. However, daily fecundity increased with increasing temperatures up to $20^{\circ}C$ showing 2.9 nymphs per day and thereafter decreased. Net reproduction rate ($R_0$) was highest of 58.7 at $15^{\circ}C$. The intrinsic rate of increase per day ($r_m$) and the finite rate of increase per day (${\lambda}$) were highest of 0.27 and 1.32, respectively and the doubling time (Dt) was shortest of 2.52. the mean generation time (T) was 10.99 at $22.5^{\circ}C$.

  • Adult development and fecundity of the green peach aphid, Myzus persicae $S\H{u}lzer$, were studied at $15{\sim}32.5^{\circ}C$ with $60{\sim}70%$ RH under 16L:8D and the results were put together to build a life table. The longevity shortened as temperatures rose at and below $25^{\circ}C$ whereas it remained relatively constant at $27.5^{\circ}C$. Total fecundity was not significantly different at all temperatures except at $30^{\circ}C$. Daily fecundity gradually increased from $15\;to\;22.5^{\circ}C$. It was 5.1 at $25^{\circ}C$ and as temperatures either went down or up, it decreased to 2.8 at both $15^{\circ}C\;and\;30^{\circ}C$. Fecundity model built from total fecundity at various temperatures suggests that $18.3^{\circ}C$ was the optimum temperature for the maximum progeny of 51. Net reproduction rate RO was highest of 36.5 at $27.5^{\circ}C$. The intrinsic rate of increase per day $r_m$ and the finite rate of increase per day $\lambda$ were highest of 0.4 and 1.6, respectively and the doubling time Dt was shortest of 1.6. Constructed life table suggests that the optimum temperature for adult development for the green peach aphid was $27.5^{\circ}C$ at which the mean generation time was 8.1.
