A survey research was conducted for a sample of 306 adult children who have an elderly parent or both parents alive. The purpose of the research was to test a structural equation model which specified the effects of early family relationships on comtemporary relationships and assistance patterns between adult children and their parents. The data were analyzed using EQS for Windows 5.7, utilizing maximum likelihood method. The results showed that early family relationships affected filial concern first, which in turn affected the level of assistance provided by adult children for elderly parents. No direct effect has been found between early family relationships and the level of assistance by adult children for elderly parents. Filial concern was played as an intervening variable. Early family relationships gave no direct effects to adult children's intention to assist their parents. Here again, filial concern was played as an intervening factor. Adult children's intention to assist their parents had not been led directly to provision of actual support to parents by their adult children. Thus, it was identified that intention to support is one thing, and the actual support is another. Controlling for the effects of filial concern, overall, early family relationship patterns gave no differential effects to the different aspects of support provided to parents by their adult children. On the basis of these results, this paper provided both discussions and suggestions for some strategies of intervention in the present family relationships in order for the inter-generational exchange of supports to happen in the future.

The Korean Long-Term Care Insurance (K-LTCI) provides financial support for long-term care service to people who need various types of assistance with daily activities. As the number of elderly people in Korea is expected to increase in the future, the demand for long-term care insurance would also increase over time. Projection of future expenditure on K-LTCI depends on the number of beneficiaries within the grading system of K-LTCI based on the test scores of applicants. This study investigated the suitability of mixture distributions to the model K-LTCI score distribution using recent empirical data on K-LTCI, provided by the National Health Insurance Service (NHIS). Based on the developed mixture models, the number of beneficiaries in each grade and its variability under the current grading system were estimated by simulation. It was observed that a mixture model is suitable for K-LTCI score distribution and may prove useful in devising a funding plan for K-LTCI benefit payment and investigating the effects of any possible revision in the K-LTCI grading system.

공격적인 성향의 운전은 자동차 사고의 주요한 원인이 된다. 기존 연구에서는 공격적 성향의 운전을 검출하기 위해, 주로 청년을 대상으로 연구가 이뤄졌으며 기계학습의 순수한 Clustering 또는 Classification 기법을 통해 이뤄졌다. 그러나 노인들은 취약한 신체적 조건에 의해 젊은 운전자와는 다른 운전 강도를 가지고 있어 기존의 방식으로는 검출이 불가능 하며, 데이터를 보정하는 등의 새로운 방법이 필요하다. 그리하여, 본 연구에서는 기존의 클러스터링 기법(K-means, Expectation - maximization algorithm)에, 새롭게 제안하는 ECA(Enhanced Clustering method for Acceleration data)기법을 추가하여, 주행 차량에 위치한 스마트폰으로부터 수집된 가속도 데이터를 분석하고 공격적인 운전 형태를 검출해 낸다. ECA는 모든 피험자의 데이터에서 K-means와 EM을 통해 검출된 군집군의 데이터 중 높은 강도의 데이터를 선별하여, 특징을 스케일링한 값을 통해 모델링한다. 본 방식을 통해 기존의 연구의 순수한 클러스터링 방식과는 달리, 모든 청장년 및 노인 실험 참가자 개인들의 공격적인 운전 데이터가 검출되었으며, 클러스터링 기법간의 비교를 통해 K-means 기법이 보다 높은 검출 효율을 갖고 있음을 확인했다. 또한, K-means 방식을 검출한 공격적인 운전 데이터에서는 젊은 운전자가 노인운전자에 비해 1.29배의 높은 운전 강도를 가지고 있음을 발견했다. 이와 같이 본 연구에서 제안된 방식은 낮은 운전 강도를 갖고 있는 노인의 데이터에서 공격적인 운전을 검출 가능하게 되었으며, 특히. 제안된 방법은 노인 운전자를 위한 맞춤형 안전운전 시스템을 구축이 가능하며, 추후 다양한 연구을 통해 이상 운전 상태를 검출하고 조기 경보하는데 활용이 가능할 것이다.

We live in a digital age. Smartphones are used by everyone from children to the elderly. And many smart devices are pouring out and changing our daily life a lot. However, even in the development of this digital age, there are some marginalized groups. There are also those who are reluctant to expose their information in the digital age. They have difficulty making reservations on their smartphones, using payment systems, logging into the site using various authentication and verification procedures, and entering and leaving buildings. We still carry most IDs, seals, certificates, etc. in physical form. Those who use smartphones are enjoying the convenience of the times. However, among the underprivileged, the desire to pass everything with only one device is growing. In this study, the most suitable smart band model was proposed by collecting the Delphi survey and the opinions of the general public. Future research is required to improve practical usability and utility by developing cheaper and more convenient models.

Purpose - With rapid population aging in Korea, changes in the population structure will result in a rise in the fiscal burden. This paper investigates the effects of population aging on fiscal spending based on Korea's province data and country panel data from the OECD. Research design, data, and methodology - We use province-level fiscal data from Local Finance Integrated Open System and the Korean Statistical Information Service and also collect country panel data from the OECD. To investigate the relationship between population aging and fiscal expenditures, our analysis uses the fixed effects model. Results - The empirical analysis based on Korean local finance and country panel data show that population aging has a positive impact on social welfare expenditures and it also has a positive impact on spending related to children and the elderly, implying that population aging may lead to an increase in fiscal spending via an increase in social welfare expenditures and spending related to children and the elderly. Conclusion - These empirical results suggest that countries like Korea that expect to experience rapid population aging need to pay more attention to prepare for the expected increase in age-related spending in the near future.

Purpose : This study was to develop a strategy for modeling future workforce projections to serve as a basis for analyzing annual supply of and demand for physical therapists across the South Korea into 2030. Methods : In-and-out movement model was used to project the supply of physical therapists. The demand was projected according to the demand-based method which consists of four-stages such as estimation of the utilization rate of the base year, forecasting of health care utilization of the target years, forecasting of the requirements of clinical physical therapists and non-clinical physical therapists based on the projected physical therapists. Results : Based on the current productivity standards, there will be oversupply of 39,007 to 40,875 physical therapists under the demand scenario of average rate in 2030, undersupply of 44,663 to 49,885 under the demand scenario of logistic model, oversupply of 16,378 to 19,100 under the demand scenario of logarithm, and oversupply of 18,185 to 20,839 under the demand scenario of auto-regressive moving average (ARIMA) model in 2030. Conclusion : The result of this projection suggests that the direction and degree of supply of and demand for physical therapists varied depending on physical therapists productivity and utilization growth scenarios. However, the need for introduction of a professional physical therapist system and the need to provide long-term care rehabilitation services are actively being discussed in entering the aging society. If community rehabilitation programs for rehabilitation of disabled people and the elderly are activated, the demand of physical therapists will increase, especially for elderly people. Therefore, healthcare policy should focus on establishing rehabilitation service infrastructure suitable for an aging society, providing high-quality physical therapy services, and effective utilization of physical therapists.

This study has a purpose to devise an education program in relation to Gerontology and geriatrics applicable to Korean nurses through literature review and analysis of education programs utilized by the Geriatric Education Centers (GECs) of USA. Educational contents on gerontology and geriatrics are very diverse in precedent literatures. The education programs of GECs for health care personnel are equally very diverse. Among educational contents, subjects considered important are age-related changes, health problems of the aged, pharmacology, death, fall and osteoporosis, delirium, dementia, depression, urinary incontinence, communication with elderly. Methods used in education program are mainly seminar, workshop and lecture through internet. In addition, case study, small-group discussion and conference are also adopted. The program proposed in this study for nurses in relation to gerontology and geriatrics consists of 32 hours' education; 6 hours for age-related changes, 10 hours for health problems of the elderly, 14 hours for health problems in old age and 2 hours of communication technique. Educational method proposed is to utilize lecture through internet, direct education, workshop, practical exercise, case study and role play in parallel. This study proposed an education program on the basis of precedent literature and the program of GECs. Therefore, it is desirable to develop in the future more practical education program applicable to and required in practicing fields. Of course, this development needs to be based on nurses' educational needs by field in relation to gerontology and geriatrics.

Objective: The purpose of this systematic review and meta-analysis was to investigate age-related bimanual coordination functions in older adults. Method: Thirteen studies that compared bimanual coordination functions in older adults with those in healthy young adults qualified for this meta-analysis. We additionally categorized 21 total comparisons from the 13 qualified studies into two types of task-related moderator variables: (1) kinematic versus kinetic movements and (2) symmetry versus asymmetry movements. Results: Random effects model meta-analysis found that older adults revealed significant bimanual coordination impairments as compared with young adults (Hedges's g = -0.771; p < .0001; I² = 74.437%). We additionally confirmed specific bimanual coordination deficits using two moderator variables: 1) kinematic (Hedges's g = -0.884; p < .0001; I² = 0.000%) and kinetic (Hedges's g = -0.666; p = .023; I² = 86.170%). 2) symmetry (Hedges's g = -0.712; p = .001; I² = 74.291%) and asymmetry (Hedges's g = -0.817; p < .0001; I² = 76.322%). The moderator variable analysis indicated older adults indicated bimanual coordination deficits in the upper extremities than healthy young adults while performing kinematic bimanual coordination tasks and asymmetry coordination tasks. Conclusion: These findings suggest that developing motor rehabilitation programs based on asymmetric bimanual movement task for enhancing interlimb coordination functions of older adults may be crucial for increasing their independence in everyday activities. Given that elderly revealed the deficits in lower extremities coordination when older adults perform gait, posture, and balance, future studies should estimate lower limb coordination functions in elderly people.
