The purpose of this study is to analyze the effect of sustainability of festival in Gangwon province on satisfaction. A total of 243 questionnaires were analyzed for the tourists participating in the Gangwon - do area festival. Using SPSS Statistics 20, we conducted frequency analysis, factor analysis, reliability analysis, correlation analysis, regression analysis, and ANOVA (Variance Analysis of Variance among Respondents). The results of this study are as follows. First, the satisfaction of the local festival persistence in Gangwondo area festival was found to be higher when the service satisfaction, program satisfaction, and red general satisfaction were higher in the regional festival sustainability. And it was analyzed to have a statistically significant effect. Second, there was no statistically significant effect of participating motivation on the program festival. Third, the correlation between the persistence of local festivals and the satisfaction of the local specialties was higher in R = .812, and the t value was 21.569 (p = .000) Respectively. The purpose of this study was to examine the effect of personal factors on regional festival tourists' satisfaction with regional festival sustainability and participatory motivation for service satisfaction, program satisfaction, There is a significance of research.

This study was performed to investigate the effects of the chitosan oligosaccharide administration on the improvement of the lipid compositions, blood glucose and enzyme activities in the serum of hypercholesterolemic rats fed the experimental diets for 5 weeks. Concentrations of total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free cholesterol, cholesteryl ester ratio, triglyceride (TG), phospholipid (PL) and blood glucose in serum were higher in the hypercholesterolemic group (group CW) and cholesterol+chitosan oligosaccharide administration group (group CCW) than those in the control group (group BW, basal diet+water). But the concentrations of total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free cholesterol, cholesteryl ester ratio, TG, PL and blood glucose in serum were lower in the group CCW than those in the CW, whereas the ratio of HDL-cholesterol concentration to total cholesterol and HDL-cholesterol concentration in the group CCW were higher than in the group CW. The activities of alkaline phosphatase (ALP) and aminotransferase (AST, ALT) in serum were lower in the group CCW than in the hypercholesterolemic group CW. From the above results, it was suggested that chitosan oligosaccharide administration was effective in the prevention and improvement of the lipid level, blood glucose and enzyme activities in serum of hypercholesterolemic rats.

For the development of the chitosan industry in Korea, the catch of red snow crabs caught on the east coast is rapidly decreasing. Therefore, it is urgent to develop raw materials that can replace the red snow crab as the top priority to solve the supply and demand problems, as well as wastewater treatment costs account for a large proportion of the cost of chitosan. In order to solve the problems, continuous research on biological extraction methods such as enzymatic extraction and microbial fermentation will increase production efficiency and lower unit cost as well as chemical extraction methods. Further efficient manufacturing method can be established. Establishing of novel techniques is indispensable for production of high-purity chitosan and the ability to regulate and separate the molecular weight, as well as joint research with industry, academia and research institute for the research and development of high-functional chitosan derivatives.
