Zizyphus jujube leaf fractions (ZLFs) showed no cytotoxic effects of up to $100{\mu}g/mL$, while the anti-inflammatory effects of ZLFs were analyzed by checking the productions of nitric oxide (NO), prostaglandin $E_2$ ($PGE_2$), cyclooxygenase-2 (COX-2), and inflammatory cytokines TNF-${\alpha}$, IL-$1{\beta}$, and IL-6 in the lipopolysaccharide (LPS)-stimulated Raw264.7 macrophage up to the concentration of $100{\mu}g/mL$. ZLFs ($100{\mu}g/mL$) demonstrated a strong anti-inflammatory activity that reduced 61~85% of NO and 71~100% of $PGE_2$ production in the LPS-stimulated Raw264.7 macrophage. Even the low ZLFs concentration of $1{\mu}g/mL$ have reduced NO and $PGE_2$ production by 34~64%. Expressions of COX-2 protein were also effectively inhibited by the ZLFs. Furthermore, the TNF-${\alpha}$, IL-$1{\beta}$, and IL-6 production were significantly suppressed through the treatment of ZLFs at concentrations of 1, 10, and $100{\mu}g/mL$. In the order of the Zizyphus jujube leaf water fraction (ZLWF) < buthanol fraction (ZLBF) < ethyl acetate fraction (ZLEF) showed anti-inflammatory activity. In particular, the ethyl acetate fraction ZLEF at $100{\mu}g/mL$ showed an excellent anti-inflammatory activity by reducing the production of NO, $PGE_2$, COX-2, and inflammatory cytokines (TNF-${\alpha}$, IL-$1{\beta}$, IL-6) in the level of Raw264.7 macrophage without LPS-stimulation or even better. The results of our study suggest the potential of ZLEF for use as an excellent ant-inflammatory inhibiting mediator and may be used as a therapeutic approach to various inflammatory diseases.

The purpose of this study is to reveal the effects of the VDSPA(Vulnerability to the Different Sex's Physical Attraction) on IOM(the intention of open marriages), the mediating effect of the SAEMR(Self Acceptance of Extra-Marital Relationship) and the moderating effect of gender. This is an empirical research based on data analysis obtained by surveying 655. The notable findings are as follow: First, respondents' perceptions of their own extramarital affairs(M=2.284) and open marriages(M=2.175) are generally negative, but women were more negative than men. Second, both men and women were vulnerable to the physical attraction of the opposite sex(M=3.569), especially men than women. Third, the more vulnerable to the physical attraction of the opposite sex, the more receptive to their own infidelity. The more receptive to their own extramarital affair, the more clear their intention to open marriage. Lastly, in the case of women, it is confirmed that the vulnerability of the physical attraction of the opposite sex has a significant effect on the intention of an open marriage, with the acceptability of the one's own infidelity as a mediator. In the case of men, there is no mediating effect of accepting their own extramarital affairs, which proved to be a moderating effect by gender. Unlike men, in the case of women, it is concluded that 'accepting their own extramaritality is a critical factor that directly or indirectly has a significant effects on their intention to open marriage.

Purpose: This study was done to develop and test a structural model for caregiving experience including caregiving satisfaction and caregiving strain in families providing care for family members with a mental disorder. Methods: The Stress-appraisal-coping model was used as the conceptual framework and the structural equation model to confirm the path that explains what and how variables affect caregiving experience in these families. In this hypothesis model, exogenous variables were optimism, severity of illness and uncertainty. The endogenous variables were self efficacy, social support, caregiving satisfaction and caregiving strain. Data were collected using structured questionnaires. Results: Optimism and caregiving self-efficacy had significant direct and indirect effects on caregiving satisfaction. Optimism, severity of illness and uncertainty had significant direct and indirect effects on caregiving strain. The modified path model explained effects of optimism on caregiving self-efficacy with social support in the path structure as a mediator. Also, there were direct and indirect effects of optimism and uncertainty on caregiving satisfaction with social support and caregiving self-efficacy in the path structure as a mediators. Conclusion: Results suggest the need to improve caregiving self-efficacy of these families, establish support systems such as a mental health professional support programs for caregiving self-efficacy. Optimism, severity of illness and uncertainty perceived by families need to be considered in the development of support programs in order to increase their effectiveness.
