This paper presents a novel evaluation method of life expectancy of power system equipment. The life expectancy means expected remaining lifetime; it can be usefully utilized to maintenance planning, equipment replacement planning, and reliability assessment. The proposed method is composed of three steps. Firstly, a cumulative probability for future years is evaluated for targeted age year. Secondly, the cumulative probability is modeled by well-blown cumulative distribution function(CDF) such as Weibull distribution. Lastly, life expectancy is evaluated as the mean value of the model. Since the model CDF is established in the proposed method, it can also evaluate the probability of equipment retirement within specific years. The developed method is applied to examples of generators of combined cycle power plants to show its effectiveness.

This paper discusses life expectancy differentials of beneficiaries of national pension old-age benefit and benefit-cost analysis in Korea. These results are useful indicators for the assessment of retirement income security of beneficiaries and old-age benefits. This paper analyzes benefit-cost ratio, internal rate of return and generation transfer amount, using life tables by lifetime incomes. The result of the actuarial analysis for male life expectancy is approximately 21.69 to 24.63 years. The result of the actuarial analysis for female life expectancy is approximately 27.63 to 29.81 years. The result of the actuarial analysis of low income level is that the benefit-cost ratio is lower approximately 2.68 to 4.83%, the internal rate of return lower approximately 0.00 to 0.74%, the generation transfer amount lower approximately 3.00 to 5.74%, than total income level. The result of the actuarial analysis of high income level is that the benefit-cost ratio is higher approximately 2.07 to 4.98%, the internal rate of return higher approximately 0.03 to 1.73%, the generation transfer amount higher approximately 2.53 to 9.68%, than the total income level. The results by income varies due to the effect of income redistribution and life expectancy on the national pension.

한국, 일본, 미국의 생명표, UN의 인구연감, WHO의 세계보건통계연감 등 공식통계를 활용하여, 한국 노인의 기대여명 및 사망원인별 사망력을 미국 및 일본과 비교하여 파악하고 있다. 한국 노인의 기대여명은 미일보다 빠른 속도로 증가하고 있는데, 1970년대 중반 이후는 미국처럼 여자보다 남자 노인의 기대여명 증가가 빠르면서, 남녀 노인의 기대여명 차가 감소하고 있다. 1997년 현재 65세시 기대여명은 남자 13.64세, 여자 17.26세로 남녀간 3.62세 차이를 보이며, 출생후 남자 72%, 여자 88%가 65세까지 생존한다. 노인의 주요 사인은 미일과 마찬가지로 순환기계질환 및 악성신생물인데, 순환기계질환중 한일은 뇌혈관질환이, 미국에서는 허혈성 심장질환이 노인의 주된 사망원인이 된다. 한국 남녀 노인의 연령층과 상관없이 허혈성 심장질환 및 폐렴 사망률은 미일보다 낮고, 뇌혈관질환, 고혈압성질환, 위암, 간암, 결핵, 당뇨병, 정신 및 행동장애, 간질환 및 교통사고 사망률은 미일보다 높다. 대부분의 사망원인에서 남자사망률이 여자사망률보다 높지만, 한국의 고혈압성 질환, 간암, 폐암 및 간질환에 의한 성별 사망률 격차가 미일보다 크며, 한미일 모두 75세 이상 노인의 정신 및 행동장애에 의한 여자 사망률보다 남자사망률보다 높게 나타난다. 사망원인 생명표 작성결과를 보면, 1997년 현재 한국의 65세 남성과 여성은 순환기계질환 제거시 각각 3.47년과 2.7년을, 악성신생물 제거시 각각 3.87년과 1.58세의 기대여명 증가를 예상할 수 있고, 일본에 비해 특정 사인을 제거시 상대적으로 많은 기대여명 증가를 기대할 수 있는 사망원인은 남자 노인의 간질환 및 교통사고를 들 수 있다.

This study analyzed the work and retirement behavior of middle- and old-aged Koreans using panel-data based multi-state life table models. Compared to previous studies that have mainly focused on gender differences in the work and retirement behavior, this study also analyzed educational differences in the retirement life course. With respect to the heterogeneity of work and retirement experiences, this study finds that the retirement life course of men and women differs substantially. Despite their longer life spans, women are expected to have shorter working life expectancies but live in a non-working state longer, resulting in a substantially higher proportion of non-working state in their lives. In terms of educational differences, this study finds that there is little difference in the expected length of stay in the labor force across educational levels but that poorly educated persons are more likely to spend a greater proportion of their lives in the labor force due to their shorter non-working life expectancies.

Benefit-cost ratios are estimated using life-expectancies of the national pension old-age pensioners in Korea and a compared to whole nation. To obtain the ratios, future mortalities are estimated by multiplying the ratios of experienced mortalities for old-age pensioners to those of the whole nation and the future mortalities of the whole nation projected on an expanded CBD model. The results indicate that the life expectancies of old-age pensioners are longer than the whole nation that lead to higher benefit-cost ratios for old-age pensioners.

The purposes of this study is to calculate the gender-based Life Expectancy and Disability Free Life Expectancy of 65-year-olds in accordance with the regions of 16 in Korea based on the years 2005 and 2010 by using the Sullivan method. We used the Census in 2005, 2010, the Korea National Statistical Office(10% sample). We also reviewed examining the changes in LE and DFLE and understanding the relevance between the DFLE of 65-year-olds of the year 2010 and related factors. As a result of this study, it was shown that the LE of the group of all 65-year-old in Korea increased from 18.15 years in 2005 to 19.75 years in 2010 and DFLE increased from 11.41 years in 2005 to 11.64 years in 2010. Regionally, the highest LE for total of 65-year-olds was found to be the entire Jeju area and DFLE was the highest in the city of Seoul. And the highest LE and the highest DFLE for 65-year-old male were found to be in the city of Seoul. Regarding the regional LE of 65-year-old female, both in 2005 and 2010 Jeju area was seen to be the highest. The results of a correlation analysis showed that the DFLE of 65-year-olds in 2010 was found to be increasing with high LE and high population density and in regions with low average temperatures, low number of beds and low age standardized death rates of malignant neoplasms and circulatory disease.

The purpose of this study was to examine and compare factors affecting the subjective life expectancy among the elderly, and to suggest health practice and social welfare service implications for later life. A total of 4,483 seniors from the 6th wave(2016) of the Korean Longitudinal Study on Aging (KLoSA) were used for analysis. The subjects were divided into three age groups: the young-old (n=2,106, 65~74 years), middle-old (n=1,803, 75~84 years), and oldest-old (n=574, 85 years and older). Control variables were sociodemographic factors and health status factors. Independent variables were health promotion behavior, cognition of public care, participating social activity, economic activity, and receiving basic pension. The data were analyzed using hierarchical multiple regression. The main results were as follows. Health promotion behavior was associated with the young-old. Social activities and economic activity were associated with the young-old and middle-old. Receiving basic pension had a significant impact on all age groups. In the middle-old, significant results were focused on socio-demographic and health status factors compared to other groups. The results of this study will provide basic data for the elderly policy and welfare service and will help to find and improve the important factors for the life of the elderly.

In Korea, most studies have used the conventional Wolfbein and Wool method, which cannot be applied to women's work-life table because of bimodality and/or M curve of female labor force participation. The increment/decrement work-life table method, however, is equally applicable to both men and women, but requires individual data on employment transition. This paper demonstrates that the Garfinkle-Pollard method is the same as the increment/decrement work-life table method developed by Hoem, Schoen and Woodrow and adopted by BLS. The merit of Garfinkle-Pollard method is to produce work-life table using labor force participation rate without individual employment transition. This paper applies the Garfinkle-Pollard methods to the estimation and projection of work-life of Korean labor force for the period of 2000-2050, using the abridged life tables provided by Korean National Statistical Office and a projection of labor force participation rates. The work-life expectancy at 65 is 5.8 years for men and 4.1 years for women in 2000, and it increased to 7.7 years for men and 5.1 years in 2050. However, differences in work-life expectancy are found depending on the data processing of elderly labor force participation and mortality assumption. Detailed data on elderly labor force participation and further study on future mortality are required to estimate and project more accurate work-life expectancy.
