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 was conducted to investigate the chemical characteristics of Gochujang with different amounts of sweet persimmon powder added during fermentation at $20^{\circ}C$ for 90 days, in an effort to improve its taste and organoleptic quality. The moisture content was shown to be inclined to increase in all the treatments throughout the fermentation. There was no significant difference between the paste with sweet persimmon powder and the control. The pH showed a tendency to decrease with increased fermentation time in all the samples during fermentation, keeping a pH range of 4.64-4.67 after 60 days of fermentation. On the contrary, the titratable acidity increased during fermentation, showing a level of 0.147-0.156 mg% in the paste with sweet persimmon powder on the 90th day of fermentation. The sugar content was shown to be $33.67-39.67^{\circ}Brix$ in the early stage of fermentation, revealing a tendency to in crease with an increase in the amount of sweet persimmon powder added. The amino-type nitrogen content was at the 241.27-245.47 mg% level in the early stage of fermentation, and appeared to be significantly high (p<0.05) in the treatments with 3 and 4% sweet persimmon powder added, respectively, after 60 days of fermentation. The content was within the range of 357.47-371.53 mg% on the 90 th day of fermentation in the final stage, showing an increase trend throughout the fermentation. The alcohol content gradually increased with an increase in fermentation time, showing a range of 0.94-0.10% on the 90th day of the final stage of fermentation. Moreover, the content was highest (0.96-0.108%) on the 70th day of fermentation, demonstrating a trend to slightly decline in all the treatments thereafter.

This study was aimed to investigate the motivators of smoking in 300 subjects using convenient extraction in one hospital. After informed consent, the survey that consisted of general characteristics, health behavior, stage of change, health behavior-related-perceived benefit, health behavior-related-perceived barrier, health behavior-related-family support, oral health behavior, subjective oral health and others was carried out. The smoking rate was higher in case of male (sex), high school graduates (education) and 2~3 million Korean won (KRW) (monthly income). The present smokers responded lower oral health behavior (p<0.001), lower health behavior-related-perceived benefit (p=0.021), higher health behavior- related-perceived barrier (p<0.001) and lower stage of change (p<0.001). The oral health related variables were not influenced by smoking. In logistic regression model, odds ratios in smoking were 0.378 in below average (health behavior-related-perceived barrier), 4.746 in below average (stage of change), 12.743 in male (sex) and 3.271 in 2~3 million KRW (monthly income/standard : over 3 million KRW). It was suggested that oral health related manpower should take account of not only smoking-related oral health but also motivators of smoking as to deliver effective no-smoking program.

Health behavior is one component of life style and is defined as behaviors performed by a person to protect, promote, or maintain the their health. General health behavior habits include not smoking, weight management, moderate drinking, regular exercise. The aim of this study was to analyze the relationship between toothbrushing and general health behaviors in 1,013 adults using data from the 2008 Daejeon Health Promotion Survey. Results showed no significant difference by region in general health behavior and toothbrushing. Smoking, alcohol consumption and toothbrushing frequency were related to sex, age, monthly income, occupation, and the degree of obesity. The predictoers of toothbrushing more than a day by losistic regression were female sex (vs. male, OR 1.88, 95% CI 1.20~2.95), age ${\geq}65$ years (vs. twenties, OR 0.51, 95% CI 0.26~0.99), monthly income 2 miillions Korean Won (KRW) to 3 millions KRW (vs. <2 million won, OR 1.58, 95% CI 1.04~2.42), white collar (vs. self-employment, OR 2.74, 95% CI 1.62~4.64), and regular exercise (vs. never, OR 1.60, 95% CI 1.21~2.11). We recommend the independent administration of oral health promotion programs focusing on aged and vulnerable social group because general health behaviors except regular exercise were not related to toothbrushing frequency.
