Rosae laevigatae Fructus extract (RLF) was tested for the effects on the urethral nitric oxide synthase (NOS) activity and Antioxidation in streptozotocin (STZ) induced diabetic rats. RLF was treated firstly into samples, and then STZ induced diabetic rats were set with them. In vitro, the urethral NOS activity was not noted but the type O activity and type conversion ratio of xanthine oxidase and the level of urethral lipid peroxide were decreased in the level of Dose of extract prepared from RLF. In vivo, after the extract was administered to the animal model for fifteen days, the urethral NOS activity increased in STZ induced diabetic rats to the level of normal rats. The content of urethral nitrite and glutathione followed by RLF pre-medicating administration, increased as highly as normal group in compare with the group treated with STZ. The type O activity and type conversion ratio of xanthine oxidase and the level of urethral lipid peroxide followed by RLF pre-medicating administration, decreased as lowly as normal group in compare with the group treated with STZ. In conclusion, the extract of RLF will be able to restore erectile dysfunction of STZ induced diabetic rats.

Despite the organizational benefits of knowledge sharing among employees, many workers are reluctant to share their knowledge with their colleagues. Most organizations have taken a lot of actions to facilitate knowledge sharing among employees, including developing reward systems, enhancing social networks and interpersonal relationships and crafting organizational cultures that support knowledge sharing. To date, however, earlier studies have demonstrated that knowledge doesn't flow easily when an organization makes a concerted effort to facilitate knowledge sharing. The issue whether or not employees are motivated to share their knowledge with others is definitely the main concern in knowledge sharing. The purpose of this study is to explore the conditions under which employees are inclined to share knowledge with other members. Specifically, we examine the effect of knowledge self-efficacy on knowledge sharing intention. In addition, we attempt to investigate medicating effects of personal outcome expectation and performance-related outcome expectation on the relationship between knowledge self-efficacy and knowledge sharing intention. To test the proposed hypotheses in our study, we collected data via a survey with a sample of 210 employees in 23 firms in Korea. The major findings of the empirical research are as follows: 1) knowledge self-efficacy was positively related with knowledge sharing intention. 2) personal outcome expectation has turned out to have a mediation effect on the relationship between knowledge self-efficacy and knowledge sharing intention. 3) performance-related outcome expectation also mediates the relationship between knowledge self-efficacy and knowledge sharing intention That is, this result indicates that knowledge self-efficacy has indirect effect on knowledge sharing intention through personal outcome expectation and performance-related outcome expectation. Based on these findings, implications of the research findings and recommendation for future research are discussed.

Purpose - This paper empirically investigates the relationship between the corporate value chain and performance of non- financial businesses of South Korean stock market companies. It aims to explore the evidence that can be used to infer the relationship between value chains and corporate performance in the case of firms forming a value chain with other companies with the means of an equity investment or a special business relationship. Design/methodology - Non-financial corporations listed from 2011 to 2017 on the securities market of South Korea are analyzed. The data used for analysis are found for transactions with the related party by year for all the corporations of non-financial industries in the securities market. Multiple analysis attempts are conducted including the relationship between the value chain and productivity, corporate value, risk-adjusted corporate value, and mediation effects of productivity. The empirical model employs sixteen variables including the value chain index which identifies its impact on various aspects of business performances. Findings - The results of this study clearly supports the phenomenon that corporate productivity and value are enhanced when the corporation expands its value chain established with domestic related firms and overseas companies. Such a positive effect is statistically significant even after the possible risk factors that accompany the expansion of value chain were considered, and productivity plays the role as a medicating variable in the effect of the value chain on the corporation values. Originality/value - The findings of this study confirms that domestic companies' expansion of their value chain centered on the related firms overseas that helped them in terms of the maximization of their productivity and corporate values. This study shows that Korean government's policy on expanding the corporate GVC can enhance the productivity and value of firms. The expansion of value chain and its impact on business performance has not been explored thoroughly, although it is getting more and more important in the global trade operation.

This study identifies the relationship between the anger expression and interpersonal problems of college students, and then confirms the influence on emotion regulation difficulties as a mediating effect. And, it was conducted to understand college students who complain of interpersonal problems and to provide basic data for developing programs that can solve their problems. As a result of the study, anger expression showed a positive correlation in interpersonal relations problem and emotion regulation difficulty, and interpersonal relations problem showed somewhat high positive correlation with emotion regulation difficulty. In addition, it was found that emotion control difficulties were partially mediated in the anger expression among college students and interpersonal relationships. In conclusion, we could see the need for future research to develop educational programs that reduce the difficulty of emotion control and lead to positive anger expression among college students, and intervention programs that can improve interpersonal relationships.

This study was intended to research into the possibility of corilagin (CRN) isolated from Euphorbia helioscopia as rheumatoid arthritis drug. For the study, CRN was medicated to the abdominal cavity of collagen induced arthritis (CIA) mice that was a animal model for rheumatoid arthritis and its effects on incidence and arthritis index (AI) were studied. The results were as folllows; Medicating corilagin that were isolated from Euphorbia heliscopia to CIA mice resulted in inhibiting an incidence of arthritis and reducing in arthritis index. It was found that inflammatory cells were remarkably decreased and joint cavity was well secured. Also it was displayed that the formation of pannus was not observed and a cartilage was preserved well by cell histological research. Performing fluorescence flow cytometry of CIA mice resulted in reducing in inflammatory cells infiltrated each tissue.
