Companies engaged in the enterprise, while still at the start will have social responsibility. But recently, more and more companies will shorten the life expectancy of a corporate environment and is also rapidly changing. In this study, the longevity of global enterprises through the company's longevity factor analysis, that has continued to gain corporate answer. DuPont's global corporate giant Siemens and the longevity of the two factors in analyzing the factors that change the business portfolio, risk management, and continuous research and development, trust management, environmental management and other factors have been described. This ongoing internal and external environment analysis and core competencies by strengthening the implementation of responsible management as the core of the upcoming general management are appearing.

We propose an extension of the Lee and Jho (2015) mean reverting the two factor mortality model by incorporating a period-specific cohort effect. We found that the consideration of cohort effect improves the mortality fit of Korea male data above age 65. Parameters are estimated by the weighted least squares method and Metropolis algorithm. We also emphasize that the cohort effect is necessary to choose the base survival index to calculate longevity bond issue price. A key contribution of the article is the proposal and development of a method to calculate the longevity bond price to hedge the longevity risk exposed to Korea National Pension Services.

In this study, I examine overall conditions and problems of personal asset management processes by the old age people in Korea from the global perspectives. Major recommended policy implications for those are as follows.. First, the IRR (income replacement ratio) of public pensions in Korea is found to rank nearly the lowest among the OECD member countries. The relatively low fund performance compared to that of developed countries as well as this low IRR can be pointed out as major problems of public pension in Korea. It is recommended to reinforce specialty in fund management as a top priority to solve out these problems related with public pensions in Korea. Second, it is needed to set retirement pensions to be mandatory for almost all the firms in Korea to substitute for the above lower IRR of public pensions and to recover from the highest elderly poverty ratio among the OECD countries. Third, it is required to discuss about the expansion of tax refund policy application in the individual pension sector and many financial investment products under the correction of current budget control to motivate voluntary subscription for individual pension planning and to stabilize elderly lives of ordinary people in Korea. Fourth, it is required to induce market mechanism in controling price and longevity risk of reverse mortgages for the long-run sustainability.

당뇨병은 침묵의 살인자다. 그러나 당뇨병환자도 건강하게 장수할 수 있다. 과학적인 연구에 따르면 당뇨는 얼마나 조기에 혈당을 잘 조절하느냐에 달려 있다. 자신이 당뇨병이라는 것을 알게 된 날 즉시 혈당을 조절하면 합병증의 위험을 줄일 수 있다. 혈당이 높은 수치로 지속되면 합병증이 발생한다.

This study aims to evaluate the retirement income readiness of Korea, a country that-considering its high property asset ratio-is seeing an unprecedented rapid progression of graying. The result of analyzing 6,589 non-retired households in Statistics Korea's Survey of Household Finances (2011) is as follows. First, the Retirement Readiness Index, considering annual income and asset utilization income before including longevity risk, was 70.6. The index increased to 89.5 when utilizing real assets excluding houses and exceeded 100 when utilizing houses. Second, when designating 100 to be the life expectancy and taking into consideration longevity risk, there results were 52.5, 63.7, and 81.1, respectively. Third, since it is less likely for one to use all current financial assets as post-retirement income, the study reviewed the changes in the Retirement Readiness Index by applying three different levels of asset utilization ratios (50%, 75%, and 100%), which refer to the conversion ratios of current assets to retirement assets. This study is significant in that it considers longevity risk and applies asset utilization ratios in various ways, outside of the assumption that all current financial assets will be used as post-retirement income, to take a more realistic approach to retirement readiness.

과도한 스트레스가 만병의 근원이라는 사실은 누구나 당연히 알고 있다. 따라서 스트레스를 잘 해결한다면 만병이 발생할 가능성이 그만큼 줄어들게 되어 장수할 수 있다는 의미도 된다. 요즘 전세계를 위협하고 있는 신종플루가 가장 위험이 되는 사람들은 바로 면역력이 떨어져 있는 상태에 노출되어 있는 환자나노약자들이다. 하지만 신종플루에 의해 사망한 사람 중에 20~40대 건강한 사람들도 포함되어 있다. 그 이유가 뭘까. 바로 과도한 스트레스로 인하여 비타민C가 소모되고, 부족한 비타민C가 면역을 맡고 있는 백혈구의 기능을 떨어뜨리기 때문이다.

Road conditions which obstruct the driver from seeing road markings, such as in the evening or in the rain, due to the lack of a light source gives way to increasing the risk of traffic accidents. In order to increase road safety, the Korea Expressway Corporation set up a pilot project which used high-quality materials along a section of the Gyeongbu Expressway between Daejeon and Pangyo. There is little research on high-quality materials in the field of pavement marking. This study introduces high-quality materials used in pavement materials, presents the results of a survey conducted to examine the effect of the pilot project and analyzes traffic accident data from before and after the implementation of the pilot project. The survey results show that 87% of the respondents were highly satisfied with the pilot project. With the goal of evaluating the effect of the pilot project, this study used traffic accident data provided by the Korea Expressway Corporation accident data and performed a before-after study of the number of traffic. The results of data analysis show that there were 62 and 48 traffic accidents before and after the implementation of the pilot project. In addition, the result of Emperical Bayes Method indicates that there is an 41.7% decrease in the number of traffic accidents as an effect of High-quality Pavement Marking Materials.

This paper proposes a way to a risk quantification of public sector comparator in the value-for-money test of the BTL (Build-Transfer-Lease) scheme in rail investment projects. Two principal risks that are project delay and budget increasing costs are identified and are empirically quantified with a case study of the Haman-Jinju link. The methodology suggested is expected to be a good reference for the similar research afterwards and also to help in settling down the scheme that is only an early stage.
