Population projections provides useful basic information for the need of economic resources and labor forces. The National Office of Statistics(NSO) presents population projections for the whole country and some of higher level local governments, but not do projections of the lower level local governments. Here are some projection methods as Hamilton-Perry methods and modified auto regression methods, which are compared to cohort method published by NSO in case of Daegu metropolitan city. The simulation results are a little stagnant with modified auto regression, but a little declines are shown with NSO and HP method, for 2010, 2015 and 2020 year, respectively.

Among the various statistical factors for South Korea, the population has been steadily decreased by lower birthrate. Nevertheless, the number of household is constantly increasing amid population aging and single life style. In general, residential electricity use is more the result of the number of household than the population. Therefore, residential electricity consumption is expected to be far higher for decades to come. The existing long-term load forecasting, however, do not necessarily reflect the growth of single and two-member households. In this respect, this paper proposes the long-term load forecasting for residential users considering the effect of changes of the housing type, and in the case study the changes of the residential load pattern is analyzed for accurate long-term load forecasting.

The development of modern medicine and economic growth has caused the elderly population to increase rapidly in Korea and the country is becoming an aging society. As the population of elderly has increased the interest in silver towns has also increased. the elderly population is more affluent in the past and more willing to spend their money on themselves. This led to the need of supplying silver towns where they can have comfortable retirement. The research conducted for this study was to understand the silver town market by finding the preference of silver town service according to their life style. The target of this survey was the pre-elderly in the Cheongju area and several analysis techniques like factor analysis, crowding analysis, and conjoint analysis were used to understand the life style of the preelderly and preference factors of silver town services.

According to the Korea National Statistical Office data in 2008, the population over ages of 65 years would possess to 10.7% whole population of Korea in 2009 denoting Korea is already in the aging society. In addition, the office also expected that Korea would enter in the aged population over 65 years: 14.3% and post-aged 20.8% society in 2019 and 2026 respectively, and which suggests that an averaged age of workers in Korean industries may increase rapidly in future. The main purpose of this study is to assess the work ability and the job stress of each age group in order to identity the influential factors on those items. To this end, Questionnaires about work ability and job stress were distributed to practitioners in shipbuilding industry and statistical analysis was performed to assess work ability and the job stress based on the responses from the practitioners.

Mortality risk is a significant threat to individual life, and quantifying the risk is necessary for making a national population plan and is a traditionally fundamental task in the insurance and annuity businesses. Like other advanced countries, the sustainability of life pensions and the management of longevity risks are becoming important in Asian countries entering the era of aging society. In this study, mortality and pension value sustainability trends are compared and analyzed based on national population and mortality data, focusing on four Asian countries from 1990 to 2017. The result of analyzing the robustness and accuracy of generalized linear/nonlinear models reveals that the Cairns-Blake-Dowd model, the nonparametric Renshaw-Haberman model, and the Plat model show low stability. The Currie, CBD M5, M7, and M8 models have high stability against data periods. The M7 and M8 models demonstrate high accuracy. The longevity risk is found to be high in the order of Taiwan, Hong Kong, Korea, and Japan, which is in general inversely related to the population size.

Aging society and aged society are determined by the component ratio of the elderly to the whole population; aging society is defined as a society whose ratio of the elderly population is less than 7%, and it is called aged society when the ratio is over 14%. Korea's aging process is so fast and unprecedented over the world according to many statistical data and investigations. The purpose of this study was to provide guidance and basic data to educate the elderly for the proper use of medication and health functional food. This study was carried out on 80 subjects of age 65 or older in Cheong Jusi in Choogncheongbuk-do. They answered questionnaire that was prepared for this study. The data were collected from August 4, 2008 to August 18, 2008. The collected data were analyzed by using the SPSS 12.0OK (for window) program and Microsoft EXCEL. The following is a summary of the results of this study. First, in the aspect of purchasing, the majority of respondents bought OTC drugs and health functional food for health and illness prevention. Purchasing places of drugs were diverse. Second, in the aspect of taking drugs, the older answerers were, the higher the number of drugs being taken was. Third, in the aspect of proper storage of drugs, most respondents have no specific spaces. Finally, regarding recognition of drug abuse and disposal, most people have little awareness or have no idea.

Mobility of elderly people is an important issue in Korea (ROK) where the aging process of the population is so rapid. This paper aims to examine the unique characteristics of elderly travel behavior in comparison to younger people and the changes in such characteristics given that Korea (ROK) has the world's fastest aging population. To this end, the paper analyzes two recent large scale survey data sets, each including more than a quarter of a million individuals' travel diaries in metropolitan Seoul, collected in 2002 and 2006, respectively. The analysis found that elderly travel differs greatly from younger people's in many aspects, and the mobility of the elderly, particularly those aged 65 to 69, has increased a great deal. Recent reforms of public transportation systems in the city could contribute to the increase in elderly mobility.

As the world's aging population increases, the aging problem in China, which has a huge population, has reached a serious situation. Therefore, this study intends to present the CCRC model of smart home care. Seven application factors of CCRC of smart home care and problems of CCRC of smart home care in China were derived through theoretical review and case analysis. Based on this, this study presented a value proposition for the 7 application elements of smart home care CCRC tailored to China's aging status and future technology demand. First, it improves the environmental atmosphere and increases the comfort of the spatial environment. Second, we value the physical and environmental safety of the elderly. Third, online convenience services are provided. Fourth, we guarantee the health and psychological health of the elderly. Fifth, it increases the efficiency of responding to unexpected situations. Sixth, predict the physical condition and surrounding environment of the elderly. Seventh, add more recreational rides. Through this, we expect to improve the quality of life by providing a safe and comfortable smart service environment for the elderly.

Globally, the elderly population is increasing, making the primary concern of modern society the healthy aging and welfare and medical facilities for the elderly. However, many seniors experience cognitive decline due to aging, making cognitive activities crucial for them. In this context, a study has developed a cognitive activity support system for the elderly using the metaverse. To achieve this, the characteristics and needs of the elderly were analyzed to design an interface in the metaverse that they can easily use. Additionally, the type and difficulty of cognitive activities were adjusted to engage seniors in a captivating manner. Experimental results showed that the proposed system effectively enhances the cognitive abilities of the elderly. Thus, the personalized metaverse-based cognitive activity support system proposed in this study can be a valuable tool for improving the cognitive abilities of the elderly.
