Objectives : This study focused on Schisandrae Fructus (SF) and Perilae Folium (PF), traditional medicine herbs and health functional food in Korea, Japan and China. We investigated various pharmacological activities that include a potential source of free radical scavenging, anti-viral, anti-microbial, anti-allergy and anti-inflammatory activities. Methods : We conducted an investigation of total contents of phenolic and flavonoid compounds in these single herbal extraction with/without combined to mixture. We also measured antioxidant activities such as DPPH free radical scavenging, SOD-like scavenging, nitrite scavenging and hydroxyl radical scavenging activities, xanthine oxidase inhibition, linoleic acid peroxidation inhibition, and reducing power. Results : As the results, contents of total phenoilc compounds and flavonoids were higher in those of PF than those of SF. Those of SF+PF mixture showed the synergy effects compared with those of SF and PF single extractions. Activities of DPPH free radical and SOD-like scavenging in 1 mg/mL concentration increased in dose dependent manners. That of SF increased compared with that of PF. That of SF and PF mixture also increased compared with that of BHA as a positive control. The other antioxident activities also showed similar to patten of activity of DPPH free radical scavenging. When combined to SF and PF extractions, there was showed synergic effect compared with those of BHA, excepted activities of xanthine oxidase inhibition and reducing power. Taken together, SF and PF have high phenolic and flavonoid compounds content furthermore, antioxidant activities in SF and PF mixture showed more synergy effect compared with those of BHA. Conclusions : Therefore, these findings suggest that SF and PF mixture may offer functional materials potential for development of functional beverage. But further studies are needed for the identification of the active compounds.

This study identifies the impact of social network service (SNS) on the spatial characteristics of retail stores locations in the hyper-connected society, which have been closely related to the everyday lives of urban residents. In particular, we focus on the changes in the spatial distribution of restaurants since the information retrieval process was added to the decision-making process of a consumer's restaurant selection. Empirically, we analyze restaurants in Seoul, Korea since the smart-phone was introduced. By applying the kernel density estimation and Moran's I index, we examine the changes in the spatial distribution pattern of restaurants during the last ten years for running, newly-open and closed restaurants as well as SNS popular ones. Finally, we develop a spatial regression model to identify geographic features affecting their locations. As the results, we identified geographical variables and online factors that influence the location of restaurants. The results of this study could provide important groundwork for food and beverage location planning and policy formulation.

The results of this study are the two. First, for convergence technology and convergence technology transfer based on analysis of previous studies I suggested a framework for convergence-type technology transfer conceptualization and measurement. Second, I am compared convergence-type technology transfer to total technology transfer from public research(university and public institute) to SME. Overall, despite the trend to increase technology transfer to SMEs, convergence-type technology transfer is only 4.4%. Both total technology transfer and convergence-type technology transfer to the Industry is active to electronic components, machinery, chemicals, food and beverage, and the medical. The role of universities is emphasized in both total technology transfer and convergence-type technology transfer. There are small transactions of less than 5 million in both total technology transfer and convergence-type technology transfer. Both total technology transfer and convergence-type technology transfer to the region are concentrated in Seoul, Daejeon and Gyeonggi-do.

This study was to estimate the economic value of Gaecheon Arts Festival in Jinju, Korea. To measure the value of the festival, improved travel cost measurement that applied new weight concept from the Travel Cost Measurement(TCM) proposed by Peares(1972) was used. The total value was evaluated to approximately 2,270.057 billion KRW. The result showed that travel cost items affecting on economic value of the festival were transportation, food and beverage, shopping, accommodation, amusement and entrance fee in order. The effect of accommodation due to the visitors' surplus was small, due to day trip participation trend??. Because accommodation, shopping and entrance fee, therefore, directly affect the regional economy, it is necessary for festival planning party to develop the program for tourist accommodation and so forth.

This study was conducted to examine the sugar intake and perception of sugar reduction based on the practice of Dietary Action Guides among the college students in Cheongju. A convenience sample of 343 healthy college students(male n=195, female n=148) was divided into two subgroups based on a median split(male M=12, female M=11) of the extent to which they practice the Dietary Action Guides: low practice(LP) group(male n=117, female n=82) and high practice(HP) group(male n=78, female n=66). There was no significant difference in age, weight, and body mass index between the groups; however, among the female students, the LP group had significantly higher frequencies of snacking and smoking, and higher sweet taste perception. For both male and female students, the LP group were more likely to eat sweet snacks such as carbonated beverage, flavored milk, and snacks sold outside, and had significantly higher total sugar intake from the sweet snacks than the HP group. The percentage of exceeding the WHO recommended daily sugar intake (50 g) was significantly higher for the LP group(36.59%) than for the HP group(13.64%) among female students. The perceived necessity of the sugar intake reduction was not significantly different between the LP and HP groups. The identification of nutrition labels when purchasing snack was significantly lower for the LP group than for the HP group regardless of gender. The necessity of nutrition labels education was higher than 80 percent for both the groups. Based on these results, encouraging the practice of Dietary Action Guides seems to be helpful in reducing the sugar intake among the college students.
