Companies are increasingly performing corporate social responsibility (CSR) as part of their strategic plans, but the effect of CSR activities on short-term financial performance is disputed. Researchers have found ambiguous relationships through mediating factors, but few studies have investigated internal stakeholders in this context and the firm characteristics that moderate these relationships. This study uses a competitive mediating model that examines job satisfaction as a mediator in the relationship between CSR and short-term financial performance for Korean companies. For the analysis, data from 195 companies covering 2014 to 2017 were collected and analyzed via panel regression. The findings indicate that CSR activities had a negative effect on short-term financial performance but a positive effect on job satisfaction; however, the larger the firm, the smaller the positive effect of CSR activities. Moreover, job satisfaction positively affects short-term financial performance, and this relationship is stronger in service firms.

The two competing underlying mechanisms of anchoring, anchoring-and-adjustment and selective accessibility, have very different managerial implications for the effect of price as an anchor on willingness-to-pay (WTP). To clarify their relative roles in inducing the anchoring effect, path analysis modeling in which two paths are included in a single model was utilized. The first path proceeds directly from anchor price to WTP, representing anchor-and-adjustment. The second path, representing selective accessibility, includes a mediator formed by various explanatory variables of WTP. The results consistently show that only the direct path, anchoring-and-adjustment, is significant. The results also show that the level of available product information has no significant moderation effect on both of the paths, which implies the robustness of the result with respect to information level.

Previous works on safety behavior have paid less attention to the influence of several leadership styles on safety behavior. Among the various leadership styles, I focus on the effect of coaching leadership on safety behavior. To be specific, this paper investigates the impact of coaching leadership on safety behavior and its underlying mechanisms (mediator) as well as contextual factor (moderator). This research examines the sequential mediating effect of perceived organizational support and organizational identification in the association between coaching leadership and safety behavior. Also, work overload will negatively moderate the coaching leadership-perceived organizational support link. My results showed coaching leadership increases employee safety behavior through the sequential mediation of perceived organizational support and organizational identification. In addition, work overload functions as a negative moderator which diminishes the positive effect of coaching leadership on perceived organizational support.

This study attempted to identify multi-dimensional influencing factors of working condition, job stress and supervision affecting care service personnel's job satisfaction by using structural equation model. From the results of this study, first, working condition (B=.247), job stress (B=-.610) and supervision (B=.635) were analyzed to have statistically significant effects upon job satisfaction as a dependent variable. Approximately 34.9% of job satisfaction was found to be explained through variables put into research models. Second, supervision affecting job satisfaction was found to have mediation effects on job stress. It will be necessary to apply the method to effective manpower management plan through supervision in the manager education course to improve job satisfaction for social service delivery manpower as well as care service in the future.

The purpose of this study is to find out how a parents' mental characteristics with preschool children(self-esteem, self-efficacy, depression) has effect on a mother's parenting stress by the medium of a father's parenting stress. The fourth year data of The Korean Children Panel of the KICCE(2011) was used, and the collected data was fathers and mothers with 1,754 children who are more than 35 months but not more than 42 months. For data analysis, analysis of frequency and correlation analysis were carried out using SPSS 18.0, and they were analysed with Structural Model to observe the relationship of each variable and influence, and it was found that the goodness of fit of the model was outstanding. As a result, the psychological traits of fathers impact directly on mothers' parenting stress. Mothers' psychological features increased mothers' parenting stress by a medium of fathers' parenting stress. The study showed that fathers' parenting stress that is a mediator variable performed a role as a mediator variable.

Many researches have been reported that collagen as cellular stroma, matrix of grafting materials, mediator of agents for the purpose of promoting healing process invivo, but the responses in vivo were seen various. The goal of this experiment is to assess the effect of collagen on bony healing, through histological evaluation of implanted collagen on the calvarial defect in rats. 2-month-old Sprague-Dawley, 24 rats were used and 12 rats assigned to each group of control and test. Defect of 5mm in diameter was made on the calvarial bone with trephine bur. Following thorough saline rinse, defect of control group was left in empty and that of experimental group was filled with fibrillar collagen($COLLATAPE^{(R)}$, COLLA-TEC. INC. U.S.A.) soaked in saline. 3 rats in each group were sacrificed at 3, 7, 14, 21 days after operation respectively, and the tissue blocks were prepared for light microscope with H-E for evaluation of overall healing, with TRAP(tartrate resistant acid phosphatase) for evaluation of osteoclastic activity and with immunohistochemical staining for macrophages. The results were as follows : 1. In the control group, inflammatory responses were disappeared at day 14, but, in the experimental group inflammatory infiltrates were reduced at day 21. Thus, the experimental group showed more severe soft tissue inflammation than control group. 2. Both control and experimental group showed slight appositional growth at day 7 and gradual bony growth to 21th day. But, complete bony healing of the defect was not shown. There was no significant difference in bony healing between control and experimental group 3. Specific response of macrophages for implanted collagen was observed at day 14 in the experimental group. In conclusion, although fibrillar collagen caused inflammation of soft tissue during initial healing period, inflammatory responses by fibrillar collagen didn't inhibit bony regeneration and implanted collagen was biodegradaded by macrophages. Thus, we expect that fibrillar collagen can be used for useful mediator of graft materials or growth factors.

Background: Extracellular sulfatases (Sulfs), sulfatase 1 (Sulf1) and sulfatase 2 (Sulf2), play a pivotal role in cell signaling by remodeling the 6-O-sulfation of heparan sulfate proteoglycans on the cell surface. The present study examined the effects of Sulfs on angiotensin II (Ang II)-induced hypertensive mediator expression and vascular smooth muscle cells (VSMCs) proliferation in spontaneously hypertensive rats (SHR). Methods: Ang II receptors, 12-lipoxygenase (12-LO), and endothelin-1 (ET-1) messenger RNA (mRNA) expressions in SHR VSMCs were analyzed by real-time polymerase chain reaction and Western blotting. VSMCs proliferation was determined by [$^3H$]-thymidine incorporation. Results: Basal Sulfs mRNAs expression and enzyme activity were elevated in SHR VSMCs. However, Sulfs had no effect on the basal or Ang II-induced 12-LO and ET-1 mRNA expression in SHR VSMCs. The inhibition of Ang II-induced 12-LO and ET-1 expression by blockade of the Ang II type 2 receptor ($AT_2\;R$) pathway was not observed in Sulf1 siRNA-transfected SHR VSMCs. However, Sulf2 did not affect the action of $AT_2\;R$ inhibitor on Ang II-induced 12-LO and ET-1 expression in SHR VSMCs. The down-regulation of Sulf1 induced a reduction of $AT_2\;R$ mRNA expression in SHR VSMCs. In addition, the inhibition of Ang II-induced VSMCs proliferation by blockade of the $AT_2\;R$ pathway was mediated by Sulf1 in SHR VSMCs. Conclusion: These findings suggest that extracellular sulfatase Sulf1 plays a modulatory role in the $AT_2\;R$ pathway that leads to an Ang II-induced hypertensive effects in SHR VSMCs.

It has been reported that ginseng is effective in the central nervous system, immune system, and the strong inflammatory responses. However, there has been no research report yet about the effect of ginseng on allergic hypersensitivity reactivity. To confirm the ginseng effects on the release of mediators(histamine. leukotrienes etc.) which cause the hypersensitivity reactivity and inflammatory response, we used actively sensitized guinea pig airway tissues by utilizing the superfusion technique. In this procedure. the contractile response and mediators released after antigen stimulation of sensitized tissues, and IgG and IgE antibody products were measured in sera of immunized animals. Then the results of the controll group were compared to those of ginseng pretreatment groups. In the total saponin(TS) and panaxatriol(PT) pretreatment, histamine release decreased by $20\%$ in the tracheal tissues after active sensitization by ovalbumin(OVA, 10mg/kg), but in the lung parenchyma, histamine release decreased by $40\%.$ Panaxadiol(PD) significantly decreased histamine release by $40\%$ in the both tissues after active sensitization. TS, PT and PD of ginseng poorly blocked leukotrienes (LTs) and prostagrandin $D_2(PGD_2)$ release(less than $10\%$). Ginseng TS and PT had no effect on the serum IgG antibody production by ovalbumin, whereas PD significantly increased serum IgG antibody contents(approximately by 2 times). However, $IgG_1$ antibody products in the serum of guinea pig actively sensitized with ovalbumin after PD pretreatment were decreased, compared to that with ovalbumin alone. IgE antibody production by passive cutaneous anaphylaxis(PCA) titer in the TS pretreatment increased 3 times more than in the absence of TS(PCA titer by PT was not detected). These studies show that some ginseng saponins can in part act to inhibit mediator release in antigen - induced airway smooth muscle by inducing the IgG antibody production which has been changed in the specificity.

The study is to examine the mediating effect of psychological empowerment on the causal relationship between high-performance work system and organizational citizenship behavior. This study collected data from public organizations that are responsible for social welfare provision in Daegu, Gyeongsangbuk-Do, and Pusan in South Korea. This study employs confirmatory factor analysis in Amos 21 to find the discriminant validity of all constructs and regression analysis by Baron and Kenny (1986) to test that psychological empowerment is a mediator of the causal relationship between high-performance work system and organizational citizenship behavior. As the result of the analysis, psychological empowerment has a significant mediating effect on the relationship between high-performance work system and organizational citizenship behavior. The study suggests to the managers in social welfare organizations how they need to enhance organizational citizenship behavior through psychological empowerment themselves.
