In this paper, we analyse empirically the relations between ownership structure and cash holdings of firms listed on Korea Securities Market and Kosdaq Market of Korea Exchange. The main results of this study can be summarized as follows. Cash holdings increase as large shareholder's equity holdings increase. Cash holdings increase as the difference between first largest shareholder's and second largest shareholder's equity holdings increase, and cash holdings increase as the ownership concentration increase. Managerial ownership exert a non-linear effects on cash holdings. So to speak, at lower level of managerial ownership, managers hold more cash to pursue their own interests at the expense of minority shareholders, but at higher level of managerial ownership, the interests of managers and shareholders are aligned, and also at highest level of managerial ownership, managers hold more cash to pursue their own interests at the expense of minority shareholders. Cash holdings increase larger in owner-controlled firm than in management-controlled firm. These results support the expropriation of minority shareholders hypothesis that large shareholders can extract private benefits from corporate resources under their control at the expense of minority shareholders. This paper contributes to defining information value of large shareholder's equity holdings on cash holdings for a firms' other stakeholders such as investors and creditors, and to strengthening a legal and institutional safeguard for external minority shareholders. Ownership concentration might have negatively affected the evolution of the legal and institutional frameworks for corporate governance and the manner in which economic activity is conducted. It could be a formidable barrier to future policy reform.

The purpose of this study was to verify the effects of growth orientation, life satisfaction, perceived stress, positive psychological capital and interpersonal relationships in the group coaching program for the promotion of growth orientation for university students based on the model of the social-cognitive approach to motivation. The program consisted of eight topics: growth orientation, growth mindset and brain plasticity, self-directed goal setting, talent which is a product of ongoing effort, failure attitude and perspective change, positive emotion, thinking and behavior, value of growth orientation and self-coaching, respectively. The program comprised a total of eight sessions, 120 minutes each, and the final program was completed through a preliminary experiment with three university students. In order to verify the effectiveness of the program, 48 university students were divided into 16 in the experimental group, 16 in the comparative group, and 16 in the control group. The experimental group participated in the group coaching program to enhance the growth orientation based on the model of the social-cognitive approach to motivation developed in this study, the comparative group participated in a learning goal orientation improvement program based on an incremental implicit theory, and the control group did not carry out any program. Three groups were tested in pre, post, follow-up1(after 1 month) and follow-up2(after 3 months) in order to growth orientation, life satisfaction, perceived stress, positive psychological capital and interpersonal relationships. We performed analysis to confirm the homogeneity to the data of the three groups and to verify the interaction effects between times and groups. As a result, it was confirmed that the group coaching program to promote growth orientation, life satisfaction, perceived stress, positive psychological capital and interpersonal relationships had statistically significant effect and was more effective than the comparative program due to the larger effective size. Also, we confirmed that the coaching effect was sustained after the program was finished and more effectively maintained than the comparative program. Based on the results of this study, this study has academic implications because it verify the effectiveness of the group coaching for the promotion of the growth orientation by scient ic method.

Objectives: This study investigated the challenges of young cross-cultural individuals (CCIs) through the cultural homelessness (CH) framework. Methods: Through a survey of 151 CCIs, the study empirically examined the relationship between CH and psychological well-being (PWB), as well as the moderating role of emotional clarity (EC). Results: Results indicated that CH was significantly and negatively associated with PWB, especially on the Positive Relations with Others and Environmental Mastery dimensions. Individuals with high CH tended to have less satisfactory relationships and a reduced sense of control over daily life situations, regardless of their EC level. A significant interaction effect between CH and EC was found, specifically in Positive Relations with Others (PR) and Personal Growth (PG). For individuals with high CH, however, satisfactory relationships were dependent on their EC level; they reported more positive relationships with others when their EC levels were high. Interestingly, individuals with high CH were likely to report a high desire for personal growth regardless of their EC level, indicating that they may appear ambitious but may be experiencing unclear emotions. Conclusions: These findings suggest that CH and EC are issues that need to be dealt with simultaneously. As individuals' PWB depends not only on their CH level, but also on their EC, reducing the level of CH should not be the only goal in promoting the well-being of CCIs. Increasing individuals' EC would be just as important, as high EC, along with low CH, predicts important dimensions of PWB.

4차 산업혁명으로 기존 일자리가 사라지고 있으며, 보다 창의적인 진로전략이 요구되고 있다. 기존의 진로전략이 구직(求職), 즉 '직업을 찾는다.'는 개념이었다면, 4차 산업혁명 시대의 중요한 진로전략인 창직은 구직의 틀에서 벗어나 개인이 직업을 적극적으로 발굴하고 일자리를 창출하는데 초점을 두고 있다. 즉, 개인이 직업을 '발굴하고', '선택한다.'는 점이 중요하며, 구직이 '남이 나를 고용한다.'는데 의미가 있다면, 창직은 '내가 나를 고용한다.'는 점에서 구직자의 주체적이고 적극적인 의지를 더욱 필요로 하고 있다. 창직교육을 통해 청소년이 자신의 진로를 직접 발굴하고 선택할 수 있는 진로결정 자기효능감의 향상이 자기고용을 이루기 위한 주체적이고 적극적인 의지를 반영하는 창업의지에 미치는 영향을 분석하기 위해 본 연구를 진행하였다. 본 연구의 결과는 다음과 같다. 창직교육 프로그램을 처치한 실험집단은 총 293명으로 검증 시 진로결정 자기효능감, 대인관계기술, 자기주도 학습력, 기업가정신, 기회발견, 기회활용, 사회적 문제해결력, 창의성역량, 창업의지 전 항목에서 통계적으로 유의한 수준에서 평균값의 상승을 보였다. 창직교육 프로그램을 처치하지 않은 통제집단은 총 85명으로 사전/사후의 평균값이 미미한 수준의 차이를 보였다. 실험집단은 통제집단에 비해 자기주도 학습력과 창의성역량이 매우 두드러지게 향상되었고, 진로결정 자기효능감과 창업의지가 두드러지게 향상되었다. 반면, 통제집단은 실험집단과 비교하여 자기주도 학습력과 창의성역량이 미약하게 향상되었고, 진로결정 자기효능감도 미약하게 향상되었으나 오히려 창업의지는 감소하였다. 본 연구로 창직교육을 통한 자기주도 학습력과 창의성역량의 향상이 진로결정 자기효능감과 창업의지에 매개변수가 되어, 진로결정 자기효능감과 창업의지를 향상시켰음을 알 수 있다.

The purpose of this study was to investigate the mediating effects of rejection sensitivity in pathological narcissism and dating violence, and to verify whether there is a gender difference in each variable, further examining the gender difference in the mediating pathways. The participants of this study were 381 men and women in 20s living across the country, and online self-report surveys was conducted regarding their experiences of pathological narcissism, rejection sensitivity, and four types of dating violence. As a result of verifying gender differences, it was found that women had a higher vulnerability to narcissism, rejection sensitivity and committed more psychological violence, sexual violence, and controlling behavior than men. As a result of the mediation analysis, it was found that rejection sensitivity partial mediated the effect of pathological narcissism on psychological violence and control behavior, but it showed a complete mediation effect on sexual violence. And there was no mediating effect of rejection sensitivity between pathological narcissism and physical violence. As a result of measuring the moderating effect of gender in this mediating pathways, the moderated mediating effect of gender was verified in the effect of naricissistic grandiosity and narcissistic vulnerability on control behavior through rejection sensitivity. These results show that pathological narcissism promotes psychological and sexual violence in both men and women, and rejection sensitivity acts as a mediator in this process. In addition, the effect of pathological narcissism on the control behaviors through rejection sensitivity was significantly higher in women than in men, indicating that there are gender differences in the mediated pathways. Finally, the implications and limitations of this study and suggestions for follow-up studies were discussed.

Unsignalized intersections are classified into two-way-stop-controlled(TWSC) and all-way-stop-controlled(AWSC) intersections for the analysis of capacity and level of service. There is no AWSC intersection in Korea, but non-controlled intersections are common. Non-controlled intersections are operated only by the driver's decision without any control. However, the study for the analysis of capacity and level of service of the non-controlled intersection has been rare. As the first stage research, this study aims to determine the measure-of-effectiveness (MOE) for the performance evaluation of non-controlled intersections. The relationships between traffic volume and the intersection passing time (delay) and number of conflicts on each intersection are analyzed. It was found that the number of conflicts were more sensitive to the traffic volume compared with the delay. It means that number of conflicts can be the MOE for the performance of non-controlled intersection. The analysis of the number of conflicts and traffic volume showed a linear relationship, so that traffic volume can also be an MOE. The level of service of non-controlled intersection can be determined with either of the MOE's. Since the performance is also influenced by the ratio of traffic volumes of crossing streets, the traffic volume should be adjusted by the ratio. The capacity of non-controlled intersection was suggested to be 2,000veh/hr referring that of AWSC intersection in the USHCM. The criteria was suggested by evenly dividing the traffic volumes based on the capacity.
