This article was aimed to investigate the effects of 'values related to work-family balance' on work-family conflict and facilitation. Participants were 311 married working women, who were in the thirties fifties. The major findings of this study were as follows. First, work-orientation and extrinsic work value had significant positive influence on work-family conflict. Second, in addition that both of work-orientation and family-orientation had positive effect on work-family facilitation, it was revealed that family-orientation showed moderating effect on work-orientation and work-family facilitation. Third, the variance of independent variables on work-family facilitation was twice as much as on work-family conflict. These results indicated that 'values related to work-family balance' were important factors as well as were worthy of notice when it comes to work-family facilitation.

The current study examines the mediation effect of the work-family spillover between full-time married working women's inefficient working culture and career interruption intention. The mediation effect is tested by classifying the work-family spillover effect into two subfactors: the work-family conflict and the work-family facilitation. For this purpose, we sampled 281 full-time married working women aged between 30 and 50s and conducted a hierarchical regression analysis. The main results are as follows: both work-family conflict and work-family facilitation play the role of partial mediation. This finding implies that it is necessary to carefully examine the effects of subfactors for work-family spillover to married working women's career interruption.

This study intends to find out the influence of a consumer's shopping style on impulse buying mediated by sales promotion, based on low-cost cosmetic goods. For the study, pleasure, economical, and convenience shopping styles were set as the independent variables, and impulse buying was set as the dependent variable, and as the mediating variable between the two, sales promotions such as price discount event, free giveaway event, and visit-inducing activity were reviewed. Accordingly, the influence relation of shopping style, sales promotion, and impulse buying were reviewed with hierarchical regression analysis to examine the mutual influence relation. The data for this study employed a structured questionnaire, and 230 copies were collected against men and women in their 20s-30s, who are the main consumers of low-cost cosmetic goods, and 197 faithful responses were analyzed, and the major findings from the analysis results are as follows. First, pleasure-style consumers were found to have influenced impulse buying, while economical-style consumers were found to have a negative influence, and convenience-style was found to have no significant relation. Second, as for the examination of the mediating effect of sales promotion, price discount event, free giveaway event, and visit-inducing activity were found to have a partial mediating effect on the influence of pleasure shopping style on impulse buying, and did not fulfill the economical shopping style mediating effect condition. Also, as convenience shopping style was found to be insignificant towards impulse buying, it was excluded from the mediating effect. Such result is thought to be a useful elementary material for establishing a sales promotion strategy according to shopping styles through the analysis of styles of major consumers in order to increase the sales of businesses. The theoretical and pragmatic implications of such study results were discussed and the future study directions were suggested.

To observe the stimulating effects of low-dose ${\gamma}-radiation$ on the Chinese cabbage, $1{\sim}5$ years old seeds were cultivated in the green house and the experimental field after irradiation of $0.5Gy{\sim}30.0Gy$ and the growth characters of them were investigated. The germination rates and the seedling heights of old seeds increased positively in the green house, but different from each other depending on their period of storage. Those of 3-, 4-, and 5-year old seeds increased remarkably at the 4.0Gy-, 1.0Gy-, and 0.5Gy-irradiation group respectively. However, in the case of 1-year and 2-year old seeds, there were not significant effects of irradiation except the increase of seedling height. There were significant increasing effects of radiation on the plant height, fresh weight, and diameter of all seeds grown in the experimental field of 4.0Gy- and 8.0Gy-irradiation group, including the corresponding effects of 1-year and 2-year old seeds in 20.0Gy- and 30.0Gy-irradiation group.

Wrinkle formation is mainly attributed to the environmental factors such as UV rays, air pollution, smoking and stress etc. Especially, UV rays induce premature skin aging which is characterized by deep wrinkle, leathery dryness etc. Recently, researches on the wrinkle formation and its prevention have been the main theme in cosmetics fields. We have studied the various plant extracts having anti-wrinkle effects and finally showed that Noni (Morinda citrifolia) extracts have the efficacy of promoting the type I collagen synthesis in normal human fibroblast, using PICP assay. We purified one active compound from Noni extracts and identified its structure. It was identified as 6,7-Dimethoxy-2H-1-Benzopyran-2-one; scopoletin by $^1H-NMR,\;^{13}C-NMR,$ IR, Mass analysis. Scopoletin increased collagen synthesis in a dose dependent manner (89.5% at $0.2{\mu}g/mL$). In order to verify the anti-aging effectiveness of the cream containing 3% noni extracsts, we performed the in vivo test with some female volunteers for 12 weeks. It reduced the signs of aging, especially face wrinkles. From these results, we conclude that the noni extracts could be used as an useful anti-wrinkle agent.

Rhizobacterial strain isolated from barren soil, Bacillus subtilis RFO41 exhibits a high level of phosphate solubilizing activity and produces some phytohormones. Its promoting effect on the growth of Xanthium italicum Moore, a wild plant growing at lakeside barren land and thus a good candidate plant for revegetation of barren lakeside was evaluated in the in situ test for 19 weeks at Lake Paro, Kangwon-do. Strain RFO41 could enhance the dry weight of X. italicum by 67.7%. It also increased the shoot length of X. italicum plant by 21.1% compared to that of uninoculated control. Both growth enhancements had statistical significance. However, the inoculation did not show any effect on the root growth, which might be due to the breakage of tiny root. Denaturing gradient gel electrophoresis analysis showed that the inoculated bacteria were maintained in the soils, and the indigenous bacterial community did not exhibit any significant change. This plant growth promoting capability may be utilized as an environment-friendly and low cost revegetation method, especially for the sensitive areas such as barren lakeside lands.

Major business journals have been annually announced '100 best companies to work for'. These companies have some characteristics having not only high organization performance but also various benefit programs such as job satisfaction, organization commitment, work-family balance and positive psychology. When people have job satisfaction, organization commitment, and happiness, it will increase the positive psychology of people. Therefore, in this study, we examined the moderating effect of work-family facilitation between occupational well-being and innovative behavior. For the empirical analysis, the survey was executed on employees of 11 companies in IT, Service, and Manufacturing business field. The analysis result is as follows. First, occupational well-being gives positive(+) influence on innovative behavior. Second, the control effect of work-family facilitation in the relationship between occupational well-being and innovative behavior was significant according to statistics. The conclusion states the implications and limitations of this study, and suggests directions on future studies.
