The purpose of this study is to investigate the burden of caring for the care-givers of the elderly in Korea by using an integrated literature review method. A total of 23 studies were analyzed using a search database. When care-givers had higher sense of filial and guilt or more than two diseases, they showed high level of feeling of burden. Also, they had high level of feeling of physical burden by their oldness, service period (especially at the period of 1-3 years). In the feeling of economic burden, they had high level of feeling of burden by their oldness, or elderly's disease periods. The feeling of burden by psychological condition was found in elderly in aged and the beginning of admission of nursing home. The feeling of burden by environment situation was found when the functional status of the elderly was bad. Therefore, we need to concern care-givers's feeling of burden with elderly people in the nursing home. In the future, I believe that the findings of this study will be helpful for development of the intervention program for alleviate burden for the care-giver.

This study involved a secondary analysis of 2016 Korean National Health and Nutrition Examination Survey data to identify the relations between metabolic syndrome, physical activity, and dietary patterns in Korean adults. The ${\chi}^2$-test, t-test, and logistic regression analysis of complex samples were conducted on the data of 3,352 subjects aged 19 to 64 years with metabolic syndrome. The prevalences of metabolic syndrome among men and women were 29.7% and 16.7%, respectively. In men, the high physical activity group showed a 0.8-fold increase in the likelihood of metabolic syndrome (OR=0.8, p=.038), and higher fat intake increased the risk of metabolic syndrome 0.98-fold (OR=0.98, p=.007). In women, the high physical activity group showed a 0.7-fold increase in the likelihood of metabolic syndrome (OR=0.71, p=.034), higher carbohydrate intake increased the risk of metabolic syndrome by 1.03-fold (OR=1.03, p<.001), and that higher protein and fat intakes reduced the risk by 0.96-fold (OR=0.96, p=.009) and 0.95-fold (OR=0.95, p<.001), respectively. The study shows that to meet the challenge presented by the increasing prevalence of metabolic syndrome, efforts are needed to screen for adults at risk of the metabolic syndrome by regular physical examination and to develop and provide intervention programs that involve regular high intensity physical activity and controlled carbohydrate, protein, and fat intakes.

The purpose of this study was to compare the immediate effect of EMS (electrical muscle stimulation) on rectus femoris thickness during resisted knee extension exercise in healthy adults. This experiment was conducted on 20 healthy adults as pretest-posttest nonequivalent one group design. The subject's 1RM of both knee extension was measured indirectly using an elastic band, and the knee extension resistance exercise using an elastic band was applied to high intensity (80% of 1RM) on the right leg and low intensity (50% of 1RM with EMS) on the left leg, which were applied with 5 sets. Muscle measurements were performed on the rectus femoris (1/2 site, 1/4 site) using ultrasonography before and after exercise. There was a statistically significant difference on the thickness of the rectus femoris in low intensity exercise of the elastic band applied with EMS between pre-test and post-test (p<.05). The results of this study showed that elastic band low intensity exercise combined with EMS had an immediate effective in increasing the thickness of rectus femoris. Based on this result, it is also necessary to verify the effectiveness of intervention methods incorporating low-intensity resistance exercises applying EMS to elderly who cannot exercise high-intensity resistance training in the future, and to develop exercise programs for various body parts.
