Saponin is a main component of ginseng widely known as an oriental traditional medicinal ingredient. A variety of biological effects of saponin has been reported, but its action related to skin regeneration has remained unclear so far. In this study, the effect of saponin on matrix metalloproteinase as well as its antioxidant effect in cell free system was examined in human dermal fibroblasts. First of all, as a result of investigating the effect of saponin on cell viability using MTT assay, it was shown to increase cell viability below 10 ${\mu}g$/ml, but it also showed cytotoxicity above 25 ${\mu}g$/ml. The antioxidant effect of saponin was exerted by inhibition of $H_2O_2$ in addition to reducing power above 1 ${\mu}g$/ml. In particular, saponin showed a protective effect on DNA oxidation. Furthermore, it was observed that saponin activates MMP-2 and increases MMP-1 activity in gelatin and casein zymography analyses, respectively, indicating that saponin could have potential a therapeutic agent for anti-aging and skin regeneration.

The results of analyzing collected data with the SPSS 24.0 program showed that students without smoking experience had higher scores in brushing, oral health-related self-efficacy and oral health-related quality of life than those with smoking experience. Brushing self-efficacy was positively correlated with oral health-related self-efficacy, and oral health-related self-efficacy was positively correlated with oral health quality of life, which were all statistically significant. It was found that the presence or absence of smoking experience was associated with oral health promotion and improvement of quality of life in foreign students. Thus, the results of this study are expected to be used as basic data by conveying the necessity of developing oral health promotion programs for healthy living of foreign students.

Fourth, parental social support increased adolescents' efficacy for self-regulated learning and parental achievement pressure increased adolescents' achievement motivation. Fifth, parental expectation had positive influence on adolescents' academic achievement. Sixth, efficacy for self-regulated learning had direct positive influence on academic achievement. These results indicate that the past achievement is the most important predictor of adolescents' current academic achievement and parent-child relationship and efficacy for self-regulated learning are also important variables that influence adolescents' achievement.
