Since the mid-1990s, Korea has been aging rapidly. At the same time, real interest rates have declined sharply. This paper studies whether population aging has contributed to the real interest rate decrease in Korea. We first present empirical evidence that increases in life expectancy and the old-age-dependency ratio, and a fall in population growth, i.e., the population aging, decrease real interest rates. Then we calibrate a life-cycle model to capture the features of the old-age-dependency ratio and population growth in Korea, and show that population aging accounts for about one third of the fall in real interest rates between 1995 and 2018. Furthermore, according to simulation results, increased life expectancy is more important than decreased population growth in affecting the real interest rate decrease during the period.

In this study, I aimed to suggest political data on the plantation of chestnut trees given the local features by conducting an analysis on the economic efficiency of the plantation of chestnut trees aimed at chestnut tree plantation farmhouses (total 67 farmhouses) in Chungbuk, Chungnam, Jeonbuk, Jeonnam and Gyeongnam, which are the chief producing place in Korea. As a result, the central area (Chungbuk, Chungnam) was proven to post 2.7 times as many as the average total income, 3.9 times as many as income, and 12.1 times as many as net income per ha when compared with those in the southern area (Jeonnam, Gyeongnam). That is, the southern area demonstrated a very low economic efficiency on the plantation of chestnut trees compared with that of the central area, and this was caused by the reduction of chestnut production and the degradation of chestnut quality due to the aging of chestnut trees. Therefore, it is imperative to consistently renovate aged chestnut orchards and manage them in the southern area.

Abstract Social pathologic phenomenon such as low fertility, nuclear family and one person households seems to be on the rise as Korea moves towards being an aging society. We think many trouble is expected to be exit as aging society progresses, but there were few studies about an aging society, especially funeral culture. Appearance of the aging society in Korea similarly follows the course of Japan. So we studied about similar funeral culture of aging society in Japan and prepared for the funeral culture in Korea. This study will suggest a gaze on realistic objective point of view, through the way to illustrate exactly the concept of "funeral for family (家族葬)" among Japanese funeral culture(Syukacheu(終活), Chyokusou(直葬) and funeral for family(家族葬)) and will be expected to be an important guide for leading the funeral culture in Korea occur due to aging in future. And this study will give a chance to ruminate on our's funeral attitude about the deceased's dignity.

At present, construction automation is a critical solution for the shortage of labor and the aging of skilled workers. Especially, researches for transportation automation are achieved to improve the efficiency as the construction of tall-building construction. Transportation automation needs to control the swung member by the inertia and/or the wind-force at the end of cable. However, previous to control, the presupposition of the swing is heavily difficult work because the inertia and the wind force are irregularly changable according to work condition. Therefore, in this study, dynamic modeling of crane and simulation was performed to find the characteristic of the swing. In the result, the maximum displacement of the swung material was analyzed. And, on the basis of analysis, the criteria to decide workability of automated transportation considering the material size and the wind force onsite was proposed.

This paper aims to explain the changes of social spatiality in rural areas as seen on a sloping scale in reference of population structure and utilization of territorial assets. Guessing from the population characteristics of rural communities and farming activities in Hwangsan village of Uichon-Myeon, Geochang-Gun and Hanam village of Chogye-Myeon, Hapchon-Gun, it will become a society characterized by super-aged intensification and large-scale crop cultivation. Deokgok-Myeon and Yulji village of Hapchon-Gun are required to intake outside residents. They have to understand the complementary cooperation and become conscious of the relationship between existing residents and relocated people in Yudong village of Yokji-Myeon, Tonyoung-Si. Due to a decreasing population and the phenomena of the 'super-aged', the efforts to revive the spatial function as a living and working space while utilizing territorial assets could be challenged in these case study regions.

As disease and aging increased on the map of nuclear families, the interests in protecting individual privancy and u-Healthcare has increased as well. Until now, the health management of individual medical institutions have limited their researches on the future of offline diagnostics and treatment works, time and space only to medical services. However, in the future, healthcare through mobile medical devices to real-time online personality, mobility, and bulwark where patients can receive personal health statues anywhere seems inevitable. Therefore, in this paper, the PDA based on the each individual elderly and patients that updates their physical health statues through the signal meter management system can notify both the individual and the hospital when a medical emergency occurs. Additionally, it provides relevant information on the results of measurements monitoring system.

The purpose of this study is to forecast the ship-management market size and to propose a management improvement scheme to support Korean ship management companies in the stagnating world shipping market. Recently, global shipping companies have begun outsourcing all ship management activities. However, the Korean ship-management market represents just 3.75% of ocean shipping companies' sales, making it necessary to enlarge this market. This study performs a business analysis of ship management companies in Korea. The findings show that these companies' profitability and financial structures are not very good, mainly because of insufficient management ability and small firm sizes. Therefore, we propose that the Korean government supports crew training programs and shipping financial systems.

The Korean government has been promoting the establishment of comprehensive information systems as one of supports for preschools' administration. This support is expected to enhance the efficiency of preschool education support systems and to improve the quality of educational services. The gap between government's expectation on an introduction of the information system and preschool educators' expectations has also been an issue in deploying this new system. This study identifies user resistance factors for comprehensive preschool administration assistance systems' deployment. We find that the performance expectancy, social influence, effort expectancy, and the psychological cost of user resistance have impacts on the user resistance. When these factors related resistance are resolved in the process of systems' deployment, active participation in these systems by preschool educators would be increased.

As society becomes more complex and advanced, the risk of accidents is inevitably increased, and this is an opportunity to increase the occurrence of not only congenital disabilities but also acquired disabilities. In this situation, the use of rehabilitation robots, a complex of advanced technologies, is expected to increase steadily in the future. So the authors would take a look the technological trends and future development prospects of domestic and foreign rehabilitation robots. Until now, disability assistive robot technology has been mainly developed in the field of supporting disability with walking disabilities or work limitations rather than cognitive disabilities. However, another issue of population aging is that cognitive impairment has the potential to increase, so development of a disability assistance robot that secures user safety must be actively promoted. It is thought that empirical results should be derived and converged

The purpose of this study is to evaluate for effective eye care service to the aged population of rural community. The results was as follow. 1. The aged who were using aids such as glasesses or had difficulties in everyday life without aids account for 66%. 2. The case of having some difficulties in everyday life and not using glasesses was 68persons(28.8%). 3. as for the reason why not using visual aids, 40.7% responded that they were able to see well without it and 31.4% could not have for burden of cost though in need of it.
