This study was tested growth hormone and fatigue materials after eight-week high-intensity interval exercise to middle aged women (40's~50's women) who have been obesity without other disease. Two group of 20 candidates were randomly divided 10 persons as exercise group and control group. Exercise was conducted 8 weeks 4 days 35 minutes, before the study each group was checked vital sign for fatigue materials. It showed the following results. First, it has been increased growth hormone level after exercise program compared each group, significantly. Secondly, it has been decreased fatigue materials due to the high-strength interval workout for 8 weeks compared control as significantly. As a result, eight-week high-intensity interval exercise could be increased growth hormone levels by reducing fatigue and it might be preventing fatigue materials levels. We would suggest that high-strength interval workout for 8 weeks could have a positive effect for preventing and reducing fatigue and related disease, obesity.

Traditionally we consider the food and the medicine have common roots, that is, energies from them share the same source, and it brought us an unique food culture of our own, and nurtured an unique academic area of oriental medicated dietary therapy. Thus we devise chocolate based on oriental theory and western food and convergence prevention nutritional approach. The study analyzed and examined the nutritional composition, physical properties and analysis DPPH radical scvenging, total polyphenolic compound contents, total flavonoids contents of chocolate added with 5% tangerine peel powder(TPC). Total polyphenolic compound content of TPC was 394.1 mg GAE/100g and DPPH radical scvenging activity was 68.66% and total flavonoid content was 148.88 mg QE/100g. Antioxidative activity of TPC was significantly higher than that of come into the market milk chocolate(p<0.05). In sensory evaluation, significantly difference(p<0.05)of TPC were surface color, flavor, overall acceptance.

This research was a review and analysis of published articles and theses in Korea on Intervention Programs for patients with Diabetes Mellitus. A comprehensive search of databases was undertaken(Korean studies, Riss4u). using research terms such as"diabetes", "diabetes and education" "diabetes and exercise", "diabetes and intervention", "diabetes and education or exercise." 53 studies were analyzed focusing on type, application method, dependant variable and effect using descriptive statistics. 8 intervention type and 113 dependant variables were used. The most frequently used applied education and counseling and glycometabolism, self-care, self-efficacy the most frequently used dependant variable. The effects of dependant variables no effect or were different effects. Further reserarch in the digital convergence should requires the consideration of Structured content and exercise and the effect of the measurement variables, including the psychological variable effect.
