The purpose of this study was to investigate the degree of cognitive impairment for the elders taking part in activities at senior community center and to identify the multiple factors affecting the cognitive dysfunction of them. Data were collected for the 375 elders taking part in activities at senior community center at 4 different areas of dong, up, and myun of C-city from June 2016 to July 2016, and their general characteristics as well as health-related characteristics, depression, and cognitive dysfunction were investigated and analyzed. The results of this study showed that cognitive dysfunction was affected by the age, education, economic support, history of stroke, and exercise. The risk of cognitive dysfunction was 3.50 times higher in patients over 80 years old than patients below 74 years old(p=.002), and the lower the level of education showed the higher the risk of cognitive dysfunction(p=.036)(p<.001). In addition, the risk of cognitive dysfunction was low in the absence of a history of stroke(p=.033), and the risk of cognitive dysfunction increased by 1.84 times if they do not exercise(p=.044). Based on the present study, It is required to consider the risk factors for cognitive dysfunction efforts to prevent and manage cognitive impairment before the onset of cognitive dysfunction.

The goal of this study was 1) to compare the physical activity between the normal(NO) and obese (OB) group at baseline and 2) to investigate responses of the physical activity to a 24-week walking exercise program in both groups. A total of 29 middle-aged women was classified NO and OB group based on the BMI($25kg/m^2$). Walking exercise was designed to energy expenditure of 500 kcal per day, with a frequence of 3 days per week for 24 weeks. Body composition(Weight, BMI, BF(%), Hip, WHR) were measured at the baseline and after the walking exercise program(24 week). Physical activity were measured during 24 week for wellness convergence in the digital age. In conclusion, the current findings of this study indicate that 1) physical activity is not difference in both groups at baseline 2) 24-week walking exercise program is an effective means of improving physical activity in both NO and OB groups.

In this study, three axillary crutches(Mobilegs, KM crutch, Pro In-motion) were tested with 12 healthy male subjects by measuring the EMG activity of the latissimus dorsi and gastrocnemius and the user-perceived levels focusing on the comfort and ease of use. The result showed that the EMG activity of the gastrocnemius was significantly reduced during ambulation using Mobilegs and Pro In-motion compared with the ambulation using KM crutch, a conventional crutch. However, no statistically significant difference was found for EMG activity of the latissimus dorsi. Subjects perceived the Mobilegs to be more comfortable and easy to use than the other crutches. Theses result may delivered mostly from the characteristics of spring-loaded axillary pad and ergonomic crutch handle. The results indicate that ambulation using the spring-loaded crutch is much easy with asking less exertion at gastrocnemius. In addition, the characteristics of crutch design, such as embedded spring, makes muscles to consume less energy. When the reasonable structure and form of the axillary pad and crutch handle are applied herein, the ambulation using the crutches are perceived to comfort.

The purpose of this study is to contribute basic data toward the efficient management of Hypertension by comprehensive analysis of several factors which make influences on indicators of Hypertension management. To achieve this, using the data of 2007, 2008 Korea National Health and Nutrition Examination Survey, 2,580 adults aged over 19 who suffered from hypertension have been analyzed comprehensively. The major results can be summarized as follows: First, in regard to the influential factors for awareness and treatment of hypertension, the older the patients were, the poorer their self-rated health status were. And when they had experienced a health examination, the more likely the hypertensive patients were aware of their hypertension and took the treatment for it. Second, as for the influential factors for control of hypertension, those who were older and those who had a health examination were significantly more likely to control their hypertension irrespective of gender. However, regular drinkers fell significantly behind in that aspect. The findings of this study show that systematic hypertension management, focusing on health behavior factors that affect the level of hypertension management, in accordance with the patients' sex and age will provide a more efficient way.

The purpose of this study was to investigate effects of physical activity and sedentary life in metabolically healthy obesity(MHO) and metabolically unhealthy obesity(MUO). A total of 1585 middle-aged obesity men and women participated in this study. The subjects were divided to MHO(n=840) and MUO(n=745) by metabolic syndrome markers(National Cholesterol Education Program-Adult Treatment Panel III). We analyzed measurement data using t-test. As results, physical activity and exercise participant between group had not significant difference in men subjects. But, in women subjects, total physical activity volume and muscle strength exercise participant between group had a significant difference. In conclusion, we suggest that physical activity and exercise participant are important factors affecting health status in the same level of obesity women.
