In order to examine cause-specific mortality in Korea by comparing mortality of Japan, various mortality indicators are calculated using 1995 of ficial statistics of twonations. The mortality measures are cause-specific mortality rate by sex, age, andmarital status, cause-specific age-standardized death rate and potential years of lifelost, and their ratios by sex and nation. Items of major causes of death include allcauses (total deaths),tuberculosis, malignant neoplasm, diabetes mellitushypertensive diseases, heart diseases, cerebrovascular diseases, liver diseasestransport accidents, and suicide. Major characteristics of mortality in Korea are asfollows . (1) Death rates from most causes except suicide are higher in Korea thanJapan and especially death rates from tuberculosis, hypertensive diseases, liverdiseases, and transport accidents are higher for economically active Koreans : (2)Death rates from tuberculosis, liver diseases, transport accidents, and malignantneoplasm are salient for Korean children (3) Sex-differentials in mortality fromliver diseases, tuberculosis , and transport accidents are large for economically activeKoreans, because male mortality is higher than female mortality : (4) Suicide ratesare lower for economically active males, and higher for females aged 10s and 20s inKorea than Japan : (5) Death rates are highest f3r divorced or widowed under 45years of age depending on causes, but death rates from all causes are highest fornever-married of the age 45 and over in Korea : and (6) Sex-differentials inmortality are greatest for widowed in Korea and for divorced in Japan.

이 논문은 최근 들어 국민들의 행복감(happiness)이 어떻게 변화되어 왔는지에 초점을 두고 있다. 최근 연구논문들을 살펴보면, 미국과 영국의 경우 경기침체 등의 영향으로 국민들이 체감하는 행복감 수준이 정체내지는 줄어든 것으로 보고 되고 있다. 미국의 경우 1970년대 이래 최근 들어 여성들이 느끼는 행복감은 가장 큰 폭의 감소세를 보이고 있는 것으로 조사되고 있다. 이러한 행복감 상실의 가장 큰 주된 요인은 경기침체 등에 따른 실업률(unemployment)과 이혼 등에 따른 것으로 알려지고 있다.

This study analyzed the relationship between elderly suicide rates and socio-economic factors from the macroscopic perspectives. As certain theoretical background of elderly suicide, sociological and economic perspectives are applied. The economic factors of elderly suicide rates consisted of economic growth and unemployment rate, economic activity rate of the aged, and relative poverty rate (income inequality rate). The sociological factors included social welfare spending, divorce rate, growth rate of population aging, and elderly dependency ratio. According to research findings, first, the more economic activity of the aged is low, the more elderly suicide rate is high. Second, the more social welfare spending rate goes flat, the more elderly suicide rate is growing. Third, the more relative poverty rate (income inequality), increasing population aging rate, and elderly dependency ratio are high, elderly suicide rate goes high at the same time. Finally, this study proposed several socio-economic policy alternatives for preventing continuous growth of Korean elderly suicide rate.

This study is to examine the status and trends of regional elderly group(pre-elderly and elderly segment)'s suicide rates and socio-economic factors, to analyze the relevance of suicide rates and socio-economic factors, and to understand differential factors of elderly group's suicide rates between metropolitan areas and small-medium sized areas. For this, analysis on relevance between socio-economic factors and elderly group's suicide rates has been done using regional statistical data for the past ten years(2006~2015) by National Statistical office. According to research findings, Socio-economic factors such as welfare budget ratio, divorce rates, economic activity rates, and financial independent rates have shown different effects on elderly group's suicide rates by age range and regional characteristics. Based on these analyses, this study suggested policy tasks for alleviating suicide rates of elderly group.

This study aims to find out changes of marital status and average marital life expectancy in Korea according to educational attainment. The study produces Korean marriage life table to accomplish the goal of study by introducing Wolfbein-Wool style working life table. Specific data utilized in this study are collected from the Population & Housing Census 2005 and Death Census 2005. Educational attainment is divided into four categories to accommodate to this study: elementary school course and lower, middle school course, high school course, college course and higher. Marriage rate, divorce rate, widowhood rate and death rate according to educational attainment are used as basicdata to analyze marital life expectancy. The results of this study are as follows: 1. As subjects age is younger, the average marital life expectancy of the highly educated tends to be higher. The disparity of average marital life expectancy according to educational attainment is apt to become narrow as subjects age is older. However, the gap between people who graduated from middle school and high school in older age group does not distinctive. 2. Males marital life expectancy is higher than females controlling for their educational attainment. 3. Males live with their wife for most of their lives but females live alone more than 10 years in every single educational categories. Based on the above, this study concludes that the average marital life expectancy is differentiated among age and sex according to educational attainment. Marital rate tends to be higher as educational level is higher. Divorce rate is lower in the highlyeducated group as their age is younger but this is apt to reverse as age is older. Furthermore, bereavement rate shows division according to educational attainmentsince one tends to marry other who has similar level of education with him or her. Therefore, educational attainment acts as an significant factor in Korean average life expectancy.

Recognizing the importance of early childhood education, the government is preparing measures at the national level, including expanding the scope of free education for infants, linking early childhood education to elementary schools, unifying the system in charge of early childhood education, printing the cost of operating a full-time system for double-income couples, and policies for low-income infants. In Korea's childcare policy, the need for childcare has increased due to the increase of free double-income couples, the increase of nuclear families, and the increase of divorce rates. Despite the overall increase in the child care budget, Korea's child care policy shows many problems in its efficiency due to the burden of childcare facilities and childcare fees for caregivers. After looking into the theoretical contents of the free childcare policy and the corresponding child care support policy, we would like to consider ways to improve the free childcare policy.

2 ply laminated composite is regarded to simulate the interply behavior of the belt layer of the tire. It was cone with 3 dimensional FE(Finite Element) analysis to determine interply shear stress and strain. Widthwise, the shear strain was measured by the pin method. These results are compared with those of CLT(classical lamination theory) in center region and those of Kassapoglou's and Kelsey's theory in edge region. In the FE analysis. rubber is assumed as linear elastic material. and rubber/cord laminate as the orthotropic material composed of cord and rubber In the FE result, interlaminar shear stress causing the interlaminar delamination has the largest value in the edge region of the inner rubber layer. Numerical results obtained coincides with CLT well in the center region, and agrees with other theoretical result little in the edge region.

This study was conducted to propose regional policy for reducing suicide rate by confirming the change of local suicide rate for 10 years from 2005 to 2015 and the effect of change of local environmental factors influencing the change. The main results are as follows. First, the change of city, county, and province suicide rate in 10 years showed that the suicide rate decreased in order of military district, city area, and district. Second, in the case of economic factors, local suicide rate decreased as the local tax burden per capita increased, and as the financial self - reliance increased. Third, in the case of the social integration factors, the local suicide rate decreased as the ratio of the basic livelihood recipient decreased. In addition, local suicide rate decreased as the number of elderly leisure welfare facilities increased. Fourth, in the case of the social demolition factor, the region where the divorce rate is increased, the depression experience rate is increased, and the region where the rate of one person is increasing, the local suicide rate is increased. Therefore, it is expected that the local suicide rate can be reduced through efforts to improve the economic capacity of the whole region, social integration and reduction of the social disintegration phenomenon in the region.
