The study is a user experience design study on the function of action cams used for leisure activities that have been on the rise recently. Along with the video platforms that are developing in a user-friendly way, the size of the action cam market is also growing. However, there is a lack of research on the quality of a function that enhances the user experience. Thus, this study classified action cam functions according to user experience elements by using Kano Model's analysis method and in-depth interview, and analyzed how the quality of action cam functions affects the user experience by conducting a satisfaction survey by function. The results of the study have shown which functions should be improved first and which functions should be continuously researched and invested. I hope this study will contribute useful information to developing user-centered action cams.

Objective : The purpose of this study was to identify the relationships among cognitive function, activities of daily living (ADL), participation and quality of life in community-dwelling elderly. Methods : Cognitive function, ADL, participation and quality of life were assessed in the 144 elderly people residing in the community. We used MMSE-K for measuring cognitive function, K-ADL for ADL, K-ACS for participation, and GQOL for quality of life. Results : Cognitive function was significantly correlated with social activity of participation and quality of life (physical health, psychological health, social relations and economic level). ADL was significantly correlated with participation (instrumental ADL, leisure activity) and all sub-areas of quality of life. Social activity of participation were significantly correlated with all subarea of quality of life except physical health. Among the variables, the most relevant variable was leisure activity. Conclusion : It was related to quality of life in the order of participation, ADL, and cognitive function. Among the sub-areas of participation, leisure activity was the most correlated with quality of life. This study, thus, aimed to provide basic data for successful elderly life by examining the correlation between cognitive function, daily life activity, participation and quality of life in community-dwelling elderly.

The purpose of the present study is to investigate the effects of long-term exercise program on exercise capacity and cognitive function (MMSE) in male patients with dementia. 24 male patients were divided into two experimental groups : the exercise group (n=12) and the control group (n=12). The exercise group participated in regular exercise program for 12 months, and their exercise capacity (cardiopulmonary function, muscle strength, muscular endurance, flexibility, balance, agility) and MMSE (Mini-mental state examination) levels were evaluated at baseline (pre), after 6 months (mid) and after 12 months (post). The subjects carried on group-exercise of $VO_{2}max\;30\~60\%$, $30\~60$ minute a day, $2\~3$ times per week. Statistical techniques for data analysis was paired samples t-test. The level of statistical significance was ${\le}.05.$ The results of this study were summarized as follows: In the exercise group, there were significant differences in cardiopulmonary function, muscle strength, muscular endurance and MMSE at the times of pre & mid and pre & post, there were significant differences in balance and agility at the time of pre & post only, whereas there was no significant difference in flexibility following the long-term exercise. In the control group, there were no significant differences in all the times. Based on the results of this particular study, one year exercise program increases on the cognitive function & exercise capacity in male patients with dementia.

As the participation in marine sports activities has increased according to the increased national income, changes in lifestyle, etc., this study explored various values and possibilities towards a sport for all, which are inherent in marine sports, through the literature research with respect to leisure activities, sport for all, and marine sports. As a result of study, marine sports include the functional values, such as leisure satisfaction and welfare function, as a tool to improve the quality of life, which the sport for all may have, and not only have a positive impact on individual lives, but further, can also contribute to raising the level of social well-being. Marine sports are directly experienced physical activities utilizing nature and importantly functioning in human beings' understanding nature; especially, it could be found that they have the high emotion-educational value which could make the right personality formed for the adolescents in modern society, whose unrealistic leisure activities account for the most part of their leisure time. These results suggest that marine sports contain sufficient positive values and possibilities as a sport for all, and the value as a sport for all could be realized which marine sports may have through active participation.

This paper makes some contributions on optimal environmental taxes in the generalized utilitarian social welfare function. It is not to suggest as to appropriate environmental tax rates but to contribute the direction of environmental tax policy. The tax rates depend on parameters of individual utility function (CES utility function) and social welfare function and income tax rate. The major findings are that, as the elasticity of substitution between labor and leisure and the concavity of social welfare function increase, both the optimal tax rates and the government demogrants rise. And, as the parameter of environmental pollution in the individual utility function increases, the optimal tax rates also increase. For the future study, this model involves the income tax and the capital tax as endogenous variables and the wage changes due to international trade.

This study analyzed the impact of the well-being trends and the attributes of the choice of the walnut-cookie on the consumer's purchasing intention. The results of this study would enhance newly revised product so that brand and product marketing strategy would be strengthened. This study also would contribute for the consumer related management through systematic and exploring research regarding consumers' expectation of products' values and trends. Specific results are as followings. Well-being oriented trends had various meanings such as "Commercial Well-being", "Eco-friendly Well-being", "Physical Well-being", and " Favors for leisure". Consumer's attributes of choice for the walnut-cookie were "Branding", "The Value of Traditional Food", "Environmental Position", and "The Function of Products". And the "Popularity", "Nutrition". and the "Service" were most preferred factors to be chosen. The multiple regression analysis was tried to test the impact of demographics, well-being trend, and the attributes of choice for walnut-cookie influence on the consumer's purchasing intention.

The immune response to any stimulus is complex, requiring coordinated action by several types of cells in a tightly regulated sequence. Thus, a physical stress such as exercise may act at any number of points in the complex sequence of events collectively termed the immune response. Although exercise causes many propound changes in parameters of immune function, the nature and magnitude of such changes rely on several factors including the immune parameters of interest; type, intensity, and duration of exercise; fitness level or exercise history of the subject; environmental factors such as ambient temperature and humidity. Although regular moderate exercise appears to be important factor for increasing immunity, Athletes are susceptible to illness, in particular upper respiratory track infection, during periods of intense training and after competition. In addition, in elite athletes, frequent illness is associated with overtraining syndrome, a neuroendocrine disorder resulting from excessive training. Through this paper, we want to investigate the effects of exercise on the immunosuppression such as exercise induced lymphopenia, asthma, anaphylaxis, URT (upper respiratory track), and TB (tuberculosis) infection. and also, we want to suggest a direct mechanism, protection and therapy of exercise induced immunosuppression.

The purpose of this study was to examine the effects of 8 weeks of resistance exercise on gait-related abilities and the differences in age groups to provide reference materials for application of training by age group. Subjects in their 30s, 40s, and 50s were recruited and subjected to a lower extremity exercise, in which the intensity gradually increased three times a week for eight weeks. The gait-related variables, torque at 0.18 sec, acceleration time, and torque at 30°, were assessed through isokinetic tests before and after the 8-week training. The torque at 0.18 sec showed a significant increase in the 50s group. There was no significant difference in acceleration time according to time and group. The torque at 30° showed a significant increase in the 30s group. In conclusion, 8 weeks resistance training can increase neuromuscular activity in adults in their 50s group, and changes in training variables are needed to increase torque at 30° that affects knee stabilization in adults over 40s group.

The study aims to examine that regular leisure activity of the elderly has a beneficial effect to enhance their health condition. The elderly subjects of 164 (82 of elderly who do leisure and 82 of elderly who do not leisure) aged over 60 years in Suwon area were employed. Survey questionnaires were administered to investigate general characteristics, life style, mental status, dietary life and nutritional status. From the findings, the elderly who do leisure were highly educated, better in living status and higher employment rate. The mental status of the elderly without leisure activity was very much inferior to that of the elderly with leisure activity, representing higher prevalence rate of depression. Furthermore, the elderly who do not leisure showed higher drinking and smoking rates, irregular eating habits, poor teeth condition and chewing style as well as having eating obstacles. Mean caloric intake of both the elderly was also lower than that of RDA. The elderly who do not leisure have shown lower intakes in most of essential nutrients in contrast to the elderly who do leisure. In conclusion, the elderly with regular leisure activity seemed to have better life style and mental status, dietary life and nutritional status. Therefore, it is critically important to establish the health program combined with various leisure activity for the seniors to promote and energize the later years of life.
