The effect of surface tension and viscosity of polymer solution on the thickness of water casting membranes was studied. Spreading of polymer solutions on water surface was governed by the surface tension and viscosity of the polymer solution. The thickness of water casting membrane was affected by these two factors. The properties, mentioned above, were proportional to the polymer concentration. The order of magnitude in surface tension was PVC>PS>CA and that of viscosity was CA>PS>PVC. The difference of surface tension between water and polymer solution acts as driving force for spreading of polymer solution, but the viscosity as resistance. The thickness of polymeric membrane prepared by water casting was PS>CA>PVC. The order of membrane thickness was not as same as that of surface tension. This phenomena were due to the viscosity which acts as more effective spreading resistance than the surface tension.

This paper examines the impact of on-the-job training (OJT) programs on turnover rates and employment status in the labor market. Exploiting the administrative data (the Employment Insurance Database), we apply the propensity score matching method to investigate 1) whether OJT participation increases the probability of remaining in the labor market after the job training, and 2) whether trainees are more likely to transition to a new employer. Our findings reveal positive effects of OJT on the continuous employment (2.4~5.3%p). We also observe that trainees show lower rates of turnover for some part of the study period, from 2008 to 2015.

As per the results verified in this study for the effect, which is given to the intent for contract according to the franchisor's capacity and support factors per the founder's characteristics. Firstly, as for analysis of the effect given by the conditions of the founder to the capacity of the franchisor, the experience and the founder's self-confidence are attentively affected in the history of the franchisor among the capacity of the franchisor, and the experience and the specialized knowledge done in the number of the franchises, and the experienced, specialized knowledge and self-confidence of the founder done in the brand and the self-confidence of the founder done in the capacity of the franchisor. Secondly, as for the hypothesis, which the founder's conditions is the support of the franchisor, the experience, specialized knowledge and the founder's self-confidence attentively affected in the support for advertisement, and the capital and experience done in the educational support, and the capital and specialized knowledge and the founder's self-confidence done in the business manual and the founder's self-confidence done in the package. Thirdly, as for the effect given by the capacity of the franchisor to the intent for contract, the number of the franchises possessed the franchisor and brand are affected to the capacity of the franchisor, and fourthly, as for the hypothesis, which the support of the franchisor affects the intent for contract, the educational support, business manual and package purchase are attentively affected. Therefore, through this study, it can be known that the characteristics of the founder and the capacity and support of the franchisor are mutually related to the intent for contract.

This study aimed to examine the influence of problem gambling on suicidal ideation through depression among stayers in the area of casino and to investigate the moderated mediation effect of gender. For the purpose, this study used a sample of 298 stayers in the area of casino, and conducted data analyses by utilizing Process Macro for SPSS. The main results are as follows. First, problem gambling positively significantly influenced suicidal ideation among stayers in the area of casino. Second, depression perfectly mediated the influence of problem gambling on suicidal ideation. Third, gender moderated the influence of depression on suicidal ideation. Fourth, the moderated conditional mediation effect of gender in the influence of problem gambling on suicidal ideation through depression was found. Based on the findings, this study concludes with discussing intervention strategies to address problem gambling and suicidal ideation among stayers in the area of casino.

The purpose of this study is to identity the relationship between CAGE distance and Korean foreign subsidiaries' social responsibility, which is divided into responsive and strategic activities. The hypothesis is that CAGE distance has positive relationships with subsidiaries' social responsibility to overcome local liabilities of foreignness and acquire social legitimacy. The key findings are as follows. Firstly, culture distance has positive significant impacts on subsidiaries' social responsibility activities. It especially has positive influences on strategic CSR. Secondly, administration distance has no impacts on subsidiaries' social responsibility. Thirdly, geographic distance also has positive impacts on subsidiaries' social responsibility activities, especially on responsive CSR. Lastly, economic distance has significantly negative effects on social responsibility. This empirical study identifies the relationships between cross national distance and subsidiaries' social responsibility. Culture and geographic distance has positive influences on subsidiaries' social responsibility. Market seeking subsidiaries group shows more positive relationship between culture distance and social responsibility activities, which means that foreign subsidiaries would engage in social responsibility activities for strategic purpose.
