The objective of this study is to investigate a perceived discomfort and cause of Korean elderly in various activities such as work and leisure as well as in daily activities. 120 subjects (30 female and 30 male for each age: the young and elderly) participated in the interview type of questionnaire. Each participant answered to 41 items of activities of daily living. The examination of each item was progressed with 3 steps: whether to do the activity or not, degree of activity discomfort, and the reasons or causes of discomfort. Borg's CR10 scale is used to measure the degree of discomfort of daily activities. As a result, there are differences for the proportion of performers between two age groups, except for essential activities such as individual maintenance and housekeeping. The elderly complained about their daily activities more than the young did, and the degree of discomfort of women was significantly larger than that of men with aging. There are seven items, the mean degree of discomfort of which is over three points for the elderly, and they showed significant difference between two age groups. It was the important reason that physical capacities such as muscle strength and suppleness are declined. The results showed the characteristics of Korean elderly in the whole daily activities. These will be used to understand various life styles of them and to propose a field or direction of study related to the aging.

Purpose: This study was done to investigate the practice level of 14 health behaviors between male (N=139) and female (N=175) elderly and to identify the barriers to each health behavior of elderly people in Korea. Methods: Data were collected from 314 elderly people (65yr and older) living in metropolitan, urban, and rural areas. Descriptive statistics, $x^2$-test and ordinal logistic regression were used in data analysis using the SPSS Win 15 version. Results: 1) The performances were different in some health behaviors between male and female elderly people. Male elderly showed better performances in balanced diet, regular exercise, and more than 30 min of exercise, while female elderly showed better performances in restriction of fat and cholesterol, restriction on alcohol, and smoking. There were no differences in stress management and health prevention behaviors between the two groups. 2) The common significant barriers in health behaviors of the elderly in Korea were the lack of habit and physical discomfort. However, the lack of perceived benefit was a significant barrier in male elderly. Lack of time and lack of family support were significant barriers in female elderly people in Korea. Conclusion: These results suggest that tailored strategies should be developed considering the gender difference to reduce the main barriers of each health behavior in order to improve the health status of elderly people.

Sit to stand(STS) movement is one of the most common activity in daily life. In addition, Korean traditionally stand up from various sitting heights in one's daily life compared to other foreigners. As Korea enter rapidly to the aging society, needs of the elderly's independent life are increasing. Therefore the importance of research about the analysis of elderly's activity in daily life is rapidly increasing. In this study, we analyzed joint movements and changes of muscle length during STS(sit-to-stand) at various sitting heights(table seat, bath seat, bottom) in the Korean elderly's daily life by using the motion analysis and musculoskeletal modeling. Ten Korean elderly and young were participated in this experiment. Three heights of sitting posture which could represent typical sitting in Korean daily life were chosen as table seat(42cm), bath seat(21cm) and bottom(0cm). As the results, the elderly showed both smaller knee/hip flexion and larger trunk flexion relatively in comparison to the young during table seat STS. The elderly also showed larger dorsiflexion and smaller ROM of knee, hip, trunk compared to the young during bath seat STS. Additionally, the elderly showed larger plantarflexion, hip flexion, smaller knee flexion and trunk flexion during the first half of bottom STS and larger knee flexion, hip flexion and trunk flexion during the second half of bottom STS. In addition, we could know contraction and relaxation characters of major muscles in lower limb during various STS through the analysis of changes in muscle length by musculoskeltal modeling.

Objective : Extremely low alanine transaminase (ALT) levels are associated with all-cause mortality in frail elderly individuals; the clinical significance of ALT as a reliable biomarker is now being considered. Predicting mortality with routine tests at the time of diagnosis is important for managing patients after intracranial hemorrhage. We aimed to investigate whether an extremely low ALT level is associated with mortality in the elderly after intracranial hemorrhage. Methods : A retrospective review was performed on 455 patients with intracranial hemorrhage admitted to a university-affiliated tertiary care hospital from February 2014 to May 2019. Multivariate Cox regression analysis was performed for all ages and for each age group to determine whether an extremely low ALT level is an independent predictor of mortality only in the elderly. Results : Overall, 294 patients were enrolled, and the mean age of the subjects was 59.1 years, with 99 (33.8%) aged ≥65 years. The variables associated with all-cause mortality in all subjects were age, C-reactive protein (CRP) levels, hemoglobin (Hb) levels (<11 g/dL), and initial Glasgow coma scale (GCS) scores. In young patients, CRP, low Hb levels, and initial GCS scores were significantly associated with all-cause mortality. However, in the elderly (≥65 years), the variables significantly associated with all-cause mortality were extremely low levels of ALT (<10 U/L) (adjusted hazard ratio, 3.313; 95% confidence interval, 1.232-8.909; p=0.018) and initial GCS scores. Conclusion : Extremely low ALT level (<10 U/L) at the time of diagnosis is a significant risk factor for all-cause mortality in the elderly after intracranial hemorrhage.

Purpose: The purpose of this study was to investigate the changes of static and dynamic balance control ability according to the stability of shoes in elderly woman and female university student. Design: Cross-sectional study. Methods: Six elderly women and seven female university students were recruited for this study. The subject's static and dynamic balance were evaluated while wearing two different types of shoes (comfortable running shoe and masai walking shoe). The BT4 system was used to measure the static (postural sway area and velocity) and dynamic balance (limit of stability on forward, backward and left and right side). The measurement of static and dynamic balance control ability was performed in standing posture wearing comfortable running shoes and masai walking shoes. Results: In the static balance control ability, both female university students and elderly women showed significant increase in postural sway area and velocity when wearing unstable shoes (p<0.05) In addition, in the dynamic balance control ability, both female university students and elderly women showed significant decrease in limit of stability on forward and backward when wearing unstable shoes (p<0.05). Conclusion: In selecting shoes for the elderly, the stability of shoe should be considered for prevention of falls.

This study regards the need for jobs to overcome the poverty of the elderly in an aged society, and as well as researches ways to participate in active economic activities in old age. The results of the study are as follows. First, the legal system needs to be improved. In addition to institutional support for the expansion of jobs for the elderly, improvement of awareness of the elderly and reinforcement of infrastructure such as a delivery system are required, and a legal basis for this is needed. To this end, occupations targeting the elderly must be selected first, and legal procedures must be prepared by the government. Second, there must be social consideration and support for the elderly. Extension of the retirement age plays an important role in enhancing employment for the elderly. Along with the improvement of the legal system, social consideration is required. Therefore, since the elderly policy without social consensus is bound to fail, various support methods that can lead to social support must be devised. Third, the elderly must have a sense of poverty and willingness to rehabilitate themselves. Elderly people should not only ask for their children and social support. The elderly must be able to find a way to become the economic agent themselves. To do this, a basic awareness of the elderly poverty consciousness is needed, and a change of awareness to escape the poverty of the elderly is necessary. Therefore, the elderly need to be self-reliant, and they must choose jobs according to their own abilities. In conclusion, the elderly job program is a part of income increase that solves the poverty of the elderly in the aged society, and the elderly are required to actively participate in economic activities.

The main purpose of this research is to investigate the qualitative nature of Korean adolescents and their parent's perception of elderly parents care. In addition, this research exams the quantitative differences between the two generations in term of their elderly parents care self-efficacy and attitude towards caring for their elderly parents. Further, an examination of the parental influence upon their children's elderly parents care self-efficacy and attitude towards caring for their elderly parents. There were 2,460 participants in this study, with 820 adolescents, and 820 fathers and 820 mothers. The results of the study were as follows: First, in terms the participants perceptions of "the most difficult aspect of caring for elderly parents", the most representative response for adolescents was financial difficulties, while for parents differences in opinions. When it came to "the best aspect of caring for elderly parents" the most representative response for adolescents was harmonious family, while for parents good for children's upbringing. When it came to "actual acts (behavior) of elderly parents care" the most representative response for adolescents was living together with their elderly parents, while for parents looking after their elderly parents. When it came to "the best method of caring for their elderly parents" the most representative response for both adolescents and parents was providing a peace-of-mind for their elderly parents, followed by the second most frequent response of adolescents living together with their elderly parents, and for parents talking with their elderly parents. When it came to "how one feels when not caring for their elderly parents" the most representative response for both groups was a feeling of indebtedness. Second, for the quantitative analyses of the differences between the two generations, the parents showed a lower level of elderly parents care self-efficacy and a higher level of negative attitude towards caring for their elderly parents, when compared to the adolescents. Third, for the parental influence upon the adolescents' elderly parents care self-efficacy and attitude towards caring for their elderly parents, the only significant influence found was the mothers' elderly parents care self-efficacy.

Purpose: While Japan undergoes super aged society, Japanese Elderly Facilities are trying to keep elderly residents from social isolation and expand regional interaction. Methods: This study analyzes regional linkage characteristics through 8 cases of Aichi-Elderly Facilities which realize regional interaction and symbiosis(life together) between various generations by visiting. Result: 1) Most researched facilities except SO provide and share opportunity for interaction with community and residents through space for regional interaction including cafe and various programs and interactive settings. 2) The facility which seeks regional linkage through Mixed-use of facilities can devide into (1) Mixed-use of facilities easy to found, (2) Addition of housing function (NM, SM, DM) and (3) Mixed-use with different facilities(HY, GM) 3) The characteristics of interaction and symbiosis between generations are (1) to adopt concept of life together to have interaction possibility with young generation and children: most studied facilities except SO (2) to establish elderly residence into facility to have interaction(FE, SM, GM) or place family room or single room into elderly residence (NM, DM, BN) (3) to disperse small facilities into community (FE) or facility or community realizing symbiosis through various facility arrangement (SM, GM). 4) Therefore, this study can categorize (1) Program network, (2) Temporary interaction, (3) Symbiosis residence, (4) Symbiosis community according to characteristics which regional linkage has. Implication: Regional Linkage is an important concept to improve social interaction in community-based facilities. It is a thought-provoking concept to Korean elderly facilities because Korean facilities are still far from a city and in isolated environment.
