The study was conducted to understand the relationship among university students’ interest in horticulture, psychological well-being and social development and the influence of measured variables. In order to collect data, the surveys were executed by convenience sampling on university students attending four-year universities in Daegu and Gyeongbuk regions of South Korea during the period from July 3 to July 17, 2016. A total of 307 survey results which measured the university students’ interest in horticulture, psychological well-being and social development were analyzed. The results showed that there are differences in the interest in horticulture, psychological well-being, and social development depending on the students’ general characteristics. According to the results analyzed by t-test and one-way ANOVA, the interest in horticulture depending on gender, religion, academic marks, family life satisfaction and school life satisfaction had significant differences showing high interest for the students with religion, good academic marks, high family life satisfaction and school life satisfaction as well as female students. Psychological well-being showed significant differences in academic marks, family life satisfaction and school life satisfaction, while social development displayed significant differences in gender, grade, academic marks, family life satisfaction and school life satisfaction. According to the results analyzed by correlation analysis, there was a significant correlation among university students’ interest in horticulture, psychological well-being and sociality development. Furthermore, regression analysis verified that university students’ interest in horticulture has a positive influence on psychological well-being and social development. The results of this study implies that university students with a higher interest in horticulture have higher levels of psychological well-being and social development.

One of the most effective and safe therapeutic methods for treating vitiligo, mixed autologous keratinocytes (KCs) and melanocytes (MCs) cultures have been used for autologous cell transplantation. However, the present transplantation method is faced with a problem that may require a large amount of skin tissue and keratinocytes have limited culture potency. We have found previously that human adipose derived stromal cells (hASCs) from aspirated fat tissue could be used in place of KCs and sufficient amounts of hASCs for transplantation could be obtained by small amount of aspirated fat tissue. The present investigation was determined the effect of ASCs on ex vivo expansion MCs for transplantation. In addition, we examined for a preservation conditions of MCs which have reported low recovery rates and a slowdown in growth after cryopreservation. Various conditions including ASCs ratio, incubation period, and additive materials for MCs cultivation was determined to improve the expansion ability of MCs. The growth rate of MCs colony was elevated 6.85 folds compared the previous conditions. These MCs showed a specific expression of immature melanocyte protein, Trp-2, but did not express the mature melanocyte proteins and markers (c-kit, CD133, and etc.) of mesenchymal stem cells that represents in ASCs feeder. Results in cryopreservation experiments were determined a preservation medium for MCs showing an increased recovery rates after thawing. The characteristics of MCs after cryopreservation using a designed medium were indicated consistent morphology and immunophenotype. In conclusion, ASCs as a feeder could be used in place of keratinocytes for ex vivo expansion of MCs. For clinical trial for vitiligo patients, efficiency experiments in preclinical state should be followed.

This study was conducted to investigate the effects of Woohwangcheungsimweun (ox bezoar), deer antlers, and wild ginseng on induction of cardiomyocyte differentiation using the established mouse embryonic stem (ES) cells. The expression of atrial natriuretic peptide (ANP) was highest in Woohwangcheungsimweun treatment group. The expression of rabbit anti-GATA-4(GATA-4) and troponin (TnI) were highest in wild ginseng and Woohwangcheungsimweun treatment groups, respectively. Fluorescence activated cell sorting (FACS) analysis showed that the expression of ANP was highest in Dimethyl sulfoxide(DMSO) and Woohwangcheungsimweun treatment groups. The expression of GATA-4 was relatively high in wild ginseng treatment group. The expression of TnI was highest in Woohwangcheungsimweun treatment group. In the gene expression analysis, DMSO greatly inhibited GATA-4 expression to 25% of control. Woohwangcheungsimweun treatment caused to increase cTnI and cardiac ANP expression significantly. Wild ginseng extract upregulated GATA-4 gene expression. In conclusion, DMSO widely used as cardiomyocyte differentiation inducer did not show significant effects on the expression of ANP, GATA-4 and TnI in this study. Woohwangcheungsimweun showed upregulation of ANP and TnI expression. Wild ginseng extract showed greater effects than DMSO on GATA-4 expression. These results might suggest that the combination of Woohwangcheungsimweun and wild ginseng extract treatment can be expected to increase expressions of all three genes.
