  • In general, estimates of average service lives and of mortality functions are less well-based than most types of economic statistics published by statistical offices. Therefore, hypotheses about service lives of tangible assets and their distribution are most difficult aspects to tackle. In this paper, estimates of service lives based on directly observed data on domestic industrial property and retirement rates are presented.

  • Purpose: The purpose of this study was to investigate the effects of hospital characteristics on employment rate, working period, and retirement of ward nurses in Korea through a retrospective cohort study based on HIRAS data. Methods: Data were obtained from a report on medical care institutions of Health Insurance Review & Assessment Service (HIRAS). Data from 259,941 nurses who were working for a day or more from January 1, 2012, to December 31, 2016, at 2,942 medical care institutions were analyzed. Life table method analysis, Kaplan-Meier analysis, and Cox proportional hazard regression analysis were conducted. Results: The employment rates of 5 yeas and 10 years for the total sample were 38% and 28%, respectively. The estimated mean value of the working period was 3,642.7 days (SE: 17.4 days). Cox proportional hazard regression analyses revealed that nurses who were working at the general hospital/hospital, clinic, and nursing hospital were more likely to leave the hospital compared to those who were working at the 3rd general hospital. Nurses who were working at the medical institutions which were located in cities and countries, established by the private foundation, rated lower levels of nursing, and owned an insufficient number of beds, nurses and doctors were more likely to leave their workplace compared to those of the counterparts. Conclusion: This study indicates that hospital characteristics may play a significant role in retirement and working period of ward nurses in Korea. The improvement of hospital conditions to reduce ward nurses' retirement are needed.

  • In insurance, the surrender rate is an important variable that threatens the sustainability of insurers and determines the profitability of the contract. Unlike other actuarial assumptions that determine the cash flow of an insurance contract, however, it is characterized by endogenous variables such as people's economic, social, and subjective decisions. Therefore, a microscopic approach is required to identify and analyze the factors that determine the lapse rate. Specifically, micro-level characteristics including the individual, demographic, microeconomic, and household characteristics of policyholders are necessary for the analysis. In this study, we select panel survey data of Korean Retirement Income Study (KReIS) with many diverse dimensions to determine which variables have a decisive effect on the lapse and apply the lasso regularized regression model to analyze it empirically. As the data contain many missing values, they are imputed using the random forest method. Among the household variables, we find that the non-existence of old dependents, the existence of young dependents, and employed family members increase the surrender rate. Among the individual variables, divorce, non-urban residential areas, apartment type of housing, non-ownership of homes, and bad relationship with siblings increase the lapse rate. Finally, among the financial variables, low income, low expenditure, the existence of children that incur child care expenditure, not expecting to bequest from spouse, not holding public health insurance, and expecting to benefit from a retirement pension increase the lapse rate. Some of these findings are consistent with those in the literature.

  • The present study was conducted to devlop and appropriate retirement home model for the elderly in terms of clothing and textiles; nutrition, health, and foodservice; housing and environment; and psychological adaptation. Specifically, the purposes of the study were: 1) to provide basic guidelines for clothing by comparing the clothing behavior of the elderly living in the retirement home and those living in their own homes with family, 2) to provide basic guidelines for balanced diet and effective foodservice, 3) to develop an ideal life space and facilities, and 4) to assess the psychological characteristics of the elderly. Questionnaires, observation, experimental method, and survey of literature were used for the study. Clothing behavior showed that the elderly were much concerned about clothing, and they preferred comfortable as well as fashionable designs. The elderly in the retirement homes complained of a lack of quantity and variety in clothing. They preferred natural fiber rather than blended fabrics. Flame resistance, thermal insulation, and flexibility of textile fabrics were found to be prime considerations in manufacturing and selecting clothing materials for the elderly. The health status of the surveyed elderly was generally good, but some poor eating habits were observed. Dietary nutrients intakes were generally sufficient, but several nutrients intakes were insufficient. The level of equipment in the kitchens of the institutions was low. Furthermore, the employment rate of dietitians in institutional settings was extremely low. This resulted in a lack of systematic foodservice management. Residents in the institution were generally satisfied with present life space and facilities but this was mainly because of abandonment, adaptation, and past experience. Optimal allocation of residents per bedroom and an adequate design for storage, bathroom, utility room, and dining room were recommended. The comparison of psychological status of the elderly living at home was more stable than those living in an institution. The emotional state of the elderly living in the institution was characterized by loneliness; they did not have close interpersonal relationships or future plans. An appropriate model for the elderly was developed on the basis of these findings.

  • This study deals with the conditions of nutritional intake of the urban elderly (age sixty years and older). This study analysis is based on factors that are influenced on the prevalent conditions of dietary-intake of the urban elderly either it be for better ment of health or desire. The method of this research was based on the interview-survey with questinaire in the Seoul area. In comparison to the surveys taken of the rural society and the urban slum elderly the urban elderly standard nutritional requirements was higher. Of the standard nutritional requrieemtns the twomen's nutrition intake was higher than of the men. But still the problem of malnutrition existed in the urban elderly both men and women at the probability nutritional deficienty rate higher than 30%. The food intake frequency factors which might influence the condition of nutritional intake was significant more than condition of eating. Another important factors of the conditions of nutritioal intake of the urban elderly are one's self-consciousness of health and degree of one's will change . In healthy case of the aged, their will was almost maintained and hand -grip strength was high when they had regular meal with their family . For elderl with the lower academic career and the one with more satisfactory to his meal, their wills didn't change before or after retirement. The objectiveness of this survey is to convince the elderly that the problems of nutritional deficiency can only be solved by reeducation and to improve their nutritional diet to have the enjoyments of a healtheir elderly life.

  • In recent years, the average life span of people in advanced countries has increased. Conwequently, the number of middle-aged and old workers who have the will to work has increased. On the other hand, the declining birth rate has decreased the number of young workers. However, because many enterprises in advanced countries have extended their mandatory retirement age from 55 to 60 years, labor accidents involving aged workers are on the increase. As a result, the need for a method to evaluate the work skills of middle-age and old workers has become urgent. To explore one such method, this study investigated the relationship between aging and manual dexterity. Dexterity was found to deteriorate with age, but with large variability from individual to individual. The parameters of dexterity used in this experiment were found to be reliable.

  • Purpose: The purpose of this study is to present a plan to expand the employment of the elderly in Small business as one of the ways to solve the problem of the supply and demand of the company due to the aging population and the problem of the elderly poverty. Research design, data and methodology: The method of this study is a qualitative research method, and the researcher visited a small and medium-sized company directly and collected data by conducting an in-depth interview with a business owner. The interview period was conducted on a total of 15 business owners from November 5, 2013 to November 18, 2013. Results: First, the reason why companies hire the elderly is because they are suitable people, and the reason why they are not employed is because the elderly are not suitable. Second, it was found that the most recruiting paths continued to work after retirement. Third, the strengths of the elderly in their businesses were diligence, integrity, leadership, wisdom, warmth, and skill. Disadvantages the elderly in their businesses include wanting to be treated as an adult, poor productivity, poor accuracy, and health risks. Fourth, in case of hiring the elderly, they were considering convergence with young employees, and it was suggested that there are no difficulties in being an elderly because the companies hiring the elderly use the elderly according to the characteristics of the elderly. Fifth, It is realistic to actively utilize the employment system after retirement. Sixth, it was found that, unlike young people, it is not easy to recruit people on the Internet, so it is necessary to improve the system. Lastly, some industries clearly distinguished between the jobs of the elderly and the jobs of the young, but in many industries, it was desirable to create jobs for the elderly by harmonizing the main and secondary jobs. Conclusion: Ultimately, the work of the elderly in small and medium-sized enterprises should be reborn as a high-quality job that can solve the poverty of the elderly by working as a regular worker in the enterprise, rather than simply working for the elderly.

  • Estimation of mortality behavior of a industrial property are useful for calculating depreciation and making management decisions relating to property. The common methods of computing depreciation require an estimation of service life, and some methods may require an estimate of life expectancy. Estimation of service life and life expectancy can be computed from a smoothed and extended life table of original life tables developed through life analysis techniques. Several actuarial techniques are available to construct a life table for depreciation application. Of these methods, the graphic approach and graduation by mathematical formula are the most widely used in the field of depreciation. A commonly used technique of smoothing and of extending the life table is to fit a lows type survivor curves to the observed retirement rate by the least square method. In this paper, estimates of depreciation rate based on directly observed data of the domestic petrochemical equipments are presented.

  • The National Wealth Survey Method has been used to estimate capital stocks in Korea by the Korea National Statistical Office in every 10 years. However, this method requires huge amount of time and money, Since the Benchmark Year Method also has similar problems of difficulties to estimate the annual retirement rate and depreciation, the Korea National Statistical Office is now considered to adapt the Perpetual Inventory Method being used by the most OECD countries as an alternative. Hence, in this paper, the concepts of the Perpetual Inventory Method are introduced and its formation plans for the National Wealth Survey are suggested.

  • 목적: 본 논문에서는 의료기사 인력수급의 기초 자료로 사용되고 있는 오영호 연구원의 "의료기사인력수급에 관한 보고서"의 문제점을 분석하였으며 안경사 인력수급과 관리제도의 개선방안에 대하여 연구하였다. 방법: 이 보고서에 내재된 의료기사의 인력 수급과 공급 정책, 미래 안경사 수에 대한 잘못된 추계, 제한된 자료(취업률, 은퇴율, 사망률)에 의한 부정확한 예측, 미래 수요와 공급에 대한 추산에 대한 오류를 분석하였다. 결과: 안경광학과의 입학정원 산정시 정원 외 입학자 수를 배제하고 추산하여 18% 정도의 오차를 보였으며, 졸업률을 62.6%(전문대학과 산업대학 각각 78.9%와 85.98%), 취업률을 65.8%(2002년부터 2007년까지 평균 취업률 73.96%), 은퇴율을 사회복지사와 동일하게 2.3%(약사 은퇴율 1.3%)로 적용하여 객관적인 자료와 큰 차이를 보였다. 또 적절한 인구대 안경사의 비 산정에 있어서는 연령층의 의료기관 사용비율을 사용하여 안경착용자 1,280명당 안경사 1인을 제시하였으나 독일(4,706명), 미국(1,789명), 한국(1,825명당 1인)의 적용 기준과 크게 다른 수치를 적용하였다. 그리고 공급추계에서 낮은 취업률을 적용하고 현 상태를 유지하는 것이 좋다고 하면서 미취업자를 활용하자는 주장은 공급추계에 이중적 가중효과를 갖도록 하는 결과를 야기하였다. 결론: 안경사의 인력수급과 관련된 문제를 해결하기 위해서는 인원 추계 시 정확한 자료와 최적의 적용 모델을 탐색해야 하며, 적절한 인구 대 안경사 비의 산정에 독일과 같이 직무영역이 유사한 나라의 사례와 직무만족도에 대한 연구 결과를 연계하여 결정해야 한다. 안경사 공급 및 수요 추계는 통합된 연구결과가 도출된 후에 형평성이 확보된 정책을 실행해야 한다. 따라서 정부와 관련단체는 정확한 조사를 선행하고 장기적이고 체계적인 정책을 수립하고, 인력수급을 담당하는 상설기구를 만들어야 한다.
