The study aimed at investigating the living time as well as disability degree of the elderly based on daily living acting capability and living activity degree. The survey was conducted through the home-visit interview during half month at july, 1996 by the students of nursing department who were previously trained. The survey targeted the elderly aged 65 years or more living at home in rural area. The study tried to utilize Activity Inventory(AI) made for examing health and disease, disability degree, and living acting degree of the elderly. Among the AI's, there are Physical Activity of Daily Living(PADL), Instrumental Activity of Daily Living(IADL), maximum daily activity scope, and physical and mental activity level of the elderly. The daily living time is surveyed physiologic time(sleeping, eating and grooming), labor time(occupation, housekeeping and farming) and leisure time(reading, sport hobby-life). Results of the study show that social activity degree of the elderly is found to be lower than that PADL, LADL, and daily living scope. It seems that the elderly suffer from inability in daily life with lower social activity degree. But the labour time of the daily living time is the most amount time in the targeted 361 elderlys through random sampling. Therefore postponement of the disability of aging should be devised to encourage the labour activity of the elderly.

As people have gained leisure time and become more interested in sports, various industries catering to these sports, including aquatic and underwater activities are growing. Many people are getting into scuba diving, where people can explore the sea at depths of more than 40-meters. Despite the increasing demand, there are limited studies on the sport. This study aims to provide basic research on materials suitable for developing technical scuba diving suits by analyzing several areas, such as design, material, sewing patterns, etc. The following trends were observed in all wetsuits: closure designs, ergonomic patterns, practical and functional details. Neoprene was the primary material of diving suits, and various functional materials were attached to the outer fabric or lining. The seam technique which minimized water contact and improved durability was sewing. Various techniques were also applied, such as flatlock stitching, GBS, LFS, etc. Subsequent studies shall investigate consumer preference etc. and other aspects, and continue to allow for the research and development of technical diving suits.

The ultimate goal of CSV activities is to increase consumer loyalty to the company, brand or organization concerned. Thus, for a professional sports club, CSV activities will ultimately aim to enhance the loyalty of spectators who are consumers of the club. Subjects of this study are the spectators of professional volleyball. We distributed 300 survey to people who were aware of the club's CSV activities among the home spectators of Hyundai Capital SkyWalkers. Data processing was performed using SPSS 23 and AMOS 18 for the analysis of confirmed factors, correlation analysis, reliability analysis, and structural equation model analysis. From these results, we were able to come up with the social problem resolution and long-term orientation among the CSV activities of professional volleyball clubs which affect the club identification. And the identification formed within the spectators of the clubs through CSV affects the club loyalty directly or through the medium of club emotion. Professional volleyball clubs need to identify the problems the community has in planning and proceeding with CSV activities and seek strategies to address them together, and approach them from a long-term oriented perspective.

The aim of this study was to investigate kinematic mechanism of gait different road conditions(dry vs. oil) in order women. For this study, twenty older women and ten young women participated in this research. twelve infrared cameras were used to collect data. It appeared that the gait strategies of older women were slower velocity and higher CoM than young women. Depending on road conditions, gait velocities of dominant muscle older women on dry surface were faster than dominant sense older women, but those of them were inverse on oil surface. The slip displacement of dominant muscle older women was less than young women, but the slip displacement of dominant sense older women was greater than young women. In case of blind during stance phase on oil surface, the rotational motion of the ankle and knee joints were increased. In conclusion, older women were subjected to self-organization theory and phase shift in dynamic theory.
