Background: Korean ginseng (Panax ginseng C. A. Meyer) is recognized for its medicinal properties. Because ginseng is cultivated for 4 – 6 years in one place, the growing environment can affect ginseng growth. Specifically, root growth can be altered by plant hormones, which in turn, affects crop yields. Among plant hormones, cytokinin is known to increase secondary growth by promoting cambium cell division. In addition, ethylene and propiconazole can regulate root development. In this study, the effects and interactions of cytokinin, ethylene, and propiconazole on four-year-old ginseng plants were analyzed. Methods and Results: Ginseng plants were treated with each hormone every two weeks. Cytokinin (6-benzylaminopurine, 500 μM) was applied to the soil, and 100 nM of propiconazole or 100 μM of ethylene was applied in combination with cytokinin. Root width and weight, and ginsenoside content of each plant were the highest when cytokinin and propiconazole were applied together. The highest number of buds was observed under cytokinin treatment. However, no significant differences were observed in shoot growth, except for stem width. Conclusions: The greatest effect on root development was observed when cytokinin and propiconazole were applied together, and ginsenoside content increased following hormone treatment.

Purpose: The purpose of this study was to investigate the relationship between teaching effectiveness and clinical practice satisfaction among nursing students. Method: The subjects of this study were 107 junior and senior nursing students in E university. Data were collected using self-reported questionnaire including general and practicum related characteristics, teaching effectiveness of clinical instructors and clinical practice satisfaction from September 12 to September 21, 2011. Collected data were analyzed by SPSS 19 program using t-test, ANOVA with Scheffe test, and Pearson`s correlation coefficients. Result: The mean score of teaching effectiveness was 3.35(±.51), and mean of clinical practice satisfaction was 3.19±.47. There were significant differences of teaching effectiveness of clinical instrutor by satisfaction of overall clinical practicum(F=8.332, p<.001), satisfaction of practice hour(F=3.230, p=.044), and satisfaction of major(F=9.883, p<.001). There were significant differences of clinical practice satisfaction by grade(t=2.274, p=.025), motive of choosing nursing science as a major(F=3.329, p=.007), satisfaction of overall clinical practicum(F=17.437, p<.001), satisfaction of practice hours(F=9.925, p<.001), and satisfaction of nursing major(F=12.748, p<.001). Relationship between teaching effectiveness of clinical instructor and clinical practice satisfaction showed positive correlation(r=.704, p<.001). Conclusion: In this study, teaching effectiveness of clinical instructor was related with clinical practice satisfaction. Therefore, we should consider improving teaching effectiveness of clinical instructor to improve clinical practice satisfaction.
