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.

Purpose: In this study, we evaluated the effects of training for survival prediction of terminally ill patients in terms of medical professionals' confidence, accuracy and knowledge of survival prediction. Methods: Twenty-nine participants completed a self-administered questionnaire where they scored their confidence, accuracy and knowledge of survival prediction before and after the training session. The training was provided in July 2009 at a university hospital located in Gyeonggi province, Republic of Korea. The participants were instructed by a professor of family medicine specialized in hospice palliative medicine to predict survival of a case using the palliative prognostic score and objective prognostic score. The training was provided in the form of a PowerPoint presentation for 40 minutes. Results: Participants' confidence in survival prediction significantly increased from $4.00{\pm}1.73$ ($mean{\pm}SD$) (0~10, visual analogue scale) to $5.83{\pm}1.71$ after the training (P<0.001). Before training, participant's level of confidence significantly correlated with their age (P=0.04). The training significantly improved the correlation between the confidence level and the number of terminal cancer patients whom they have experienced (P=0.005 before training, P=0.017 after training). Participant's accuracy in survival prediction also significantly improved from 14 of 29 (48%) to 27 of 29 (93.1%) (P<0.001). The change in knowledge of survival prediction was too small to be statistically analyzed. Conclusion: After training, the confidence and accuracy scores significantly improved. Further study with a greater number of participants is needed to generalize this finding.
