The objective of this study was to investigate the perception of ginseng and ginseng products among university students living in Yeongsu, Ganwon-do. 196 university students participated in the survey for our study. The ginseng intakes of male students(59.1%) was significantly(p<0.05) higher than the intake of female students(40.9%). The primary reasons for consuming ginseng were to “Maintain my [one’s] health” and to, “Restore my [one’s] energy”. The reasons for not consuming ginseng were “Taste” and, “Physical constitution”. Consumers purchased the following ginseng products at the market: For males, ginseng wine(21.7%), ginseng beverage(17.4%), ginseng candy(17.4%) and ginseng kimchi(17.4%) for females, Korean ginseng snacks(23.3%), ginseng yogurt(20.9%), ginseng candy(14.0%), and ginseng jelly(11.6%).

This experiment was performed with the purpose of finding out the effect of simulated acid rain at various pH levels on the morphology and enzyme of Perilla frutescens var. japonica Hara. The pH levels of simulated acid rain ranged from pH 2.0 to pH 6.0. The experiment showed the anion concentrations in the order of SO4^-2, Cl^-, NO3, and F^-. SO4^-2 was found out to be the main factor which contributed to the rainwater acidification. A general decrease of growth in Perilla frutescens var. japonica Hara growth was shown with the decreas of pH concentration. As acidity increases, a definite reduction in the rates of germination, heigth of plant, malate dehydrogenase, and 6-phosphogluconate dehydrogenase was ovserved, but the density of spots on the leaf apex was increased.
