The purpose of this study is to verify the effect of human resource flexibility on organizational commitment and to verify the mediating effect of self-efficacy in the relationship between human resource flexibility and organizational commitment. In order to achieve this research purpose, a survey was conducted on employees working in the service industry in China, and the results of the analysis are as follows. First, it was found that technological flexibility, behavioral flexibility, and relationship flexibility, which are sub-factors of human resource flexibility, all had a significant positive effect on organizational commitment. Second, as a result of verifying the mediating effect of self-efficacy in the relationship between human resource flexibility and organizational commitment, it was verified that self-efficacy has a partial mediating effect in the relationship between technological flexibility, behavioral flexibility, relationship flexibility, and organizational commitment. Finally, the implications of this study were presented and the future research direction was discussed.

본 논문은 단기신용등급의 변화가 주가에 미치는 영향을 실증적으로 고찰함으로써 신용등급의 정보기능과 우리나라 주식시장의 효율성을 함께 검증하는데 그 목적이 있다. 단기신용등급이 변화한 104 상장기업을 대상으로 한 실증분석 결과, 우리나라의 주식시장이 기업의 재무상태와 영업상태를 수시로 주가에 반영하여 신용등급변화의 발표 자체가 갖는 정보효과는 극히 작다는 것을 보임으로써 주식시장의 효율성이 지지되었다. 신용등급변화의 정보효과가 평균적으로는 영에 가까우나 발표일 이전에 관련 정보가 주식시장에 적게 반영된 기업의 경우 신용등급변화의 정보효과가 크게 나타남을 보여줌으로써 신용등급변화의 발표가 기존 정보의 오차를 수정하는 효과가 있음을 시사하였다.

The aim of this study was to explain the mediating effects of self-control in the relationship between academic stress and impulse buying tendency. Participants were recruited from one nursing university student located in Gwangju and J city. Data were collected from 145 nursing university student. The SPSS WIN 23.0 version was used with Sobel test and Baron and Kenny's mediating effect. It was investigated whether there was a mediating effect of self-control on academic stress and impulse buying tendency. First, academic stress showed a significant effect on impulse buying tendency. Second, Self-control had a partial mediating effect in the relationship between academic stress and impulse buying tendency(z=-2.69, p<.001). To reduce the impulse buying tendency among nursing university student, it is necessary to develop education·non-education interventions that promotion self-control in addition to decreasing academic stress.

This study investigated how the big five personality traits among clinical laboratory science students affect their levels of academic satisfaction and verified the mediating effect of career preparation in the context of these personality traits influencing academic satisfaction. A total of 300 college students attending a 3-year college in Daegu were surveyed, and 260 were analyzed. SPSS 22.0 was used for statistical analysis while Baron and Kenny (1986)'s three step method was carried out for basic analysis, correlation analysis, and verification of the mediating effect of the collected data. Results of this study are as follows. Firstly, the correlation analysis between variables shows that extroversion, openness, agreeableness, and conscientiousness among the big five personality traits had significant positive relationships with academic satisfaction and career preparation while neuroticism showed a significant negative relation with academic satisfaction and no significant relation with career preparation. Secondly, the mediating effect verification found that extroversion, openness, agreeableness, and conscientiousness, but not neuroticism, had significant mediating effects; extroversion especially was confirmed to have a complete mediating effect. Thus, methods are needed to improve academic satisfaction and career preparation in college.

The purpose of this study was to 1) replicate the Wells effect(i.e., reluctance to rule against the Defendant solely on the basis of probabilistic evidence) in Korea and 2) examine the validity of an Alternative explanation(i.e., perception of risk of wrong verdict). In study 1(n=46), mock jurors in the tire-tracks condition were reluctant to rule against the defendant based on their perceived probability and this pattern was not resulted in the tire-tracks-belief condition. Therefore, the Wells effect was replicated in Korea. In study 2(n=70), we manipulated the participants' perception of risk of wrong verdict. That is, participants who were assigned in the high risk perception of wrong verdict were informed that if the defendant were found guilty, the defendant would get considerable demage both in finance and reputation of the company. Participants in the low risk perception of wrong verdict condition were informed that these demage would not be great. The results revealed that the Wells effect was pronounced in the high risk perception of wrong verdict condition. That is, participants were more reluctant to rule against the defendant when they perceive the significance of the result of wrong verdict as high. Limitations of the study and the directions for future study were discussed.

This study aims to investigate the mediation effect of creativity in the relationship between the core competencies of lifelong educators and the life competencies of adult learners. A survey was conducted for adults participating in the lifelong education programs in lifelong education institutes in Gyeonggi-do. Consequently, a toows. First, among the life competencies of adult learners, the problem solving ability showed the highest correlations with the planning, action, and support competencies, which are the sub-factors of the core cotal of 520 questionnaires were used for research analysis. The main findings of this study are as follmpetencies of lifelong educators. Among the creativity factors of adult learners, unique flexibility showed high correlations with the life competencies of adult learners. Second, the core competencies and creativity of lifelong educators had a 74.6% effect on the life competencies of adult learners. Among them, creativity was a variable that had a greater effect on the life competencies of adult leaners than on the core competencies of lifelong educators. Third, the mediation effect of creativity in the relationship between the core competencies of lifelong educators and the life competencies of adult learners was verified. The results of this study proved that the creativity of adult learners is an important variable for improving life competencies and that qualitative improvement through the core competencies of lifelong educators is required.

Recently, interest in organizational performance has been increasing due to marketization and diversification of supplier introduced in long-term care system. To analyze the effects of caregivers' calling on the organizational performance of long-term care facilities and to examine the mediating effects of job satisfaction on the path, data were collected from caregivers in Seoul and Kyonggi-do. Multiple regression analysis was used to examine the effect of caregivers' calling on job satisfaction and job performance, and the mediating effect of job analysis was tested by hierarchical regression analysis. As a result, caregivers' calling had a positive effect on job performance and job satisfaction, and the job satisfaction showed full mediation effect between caregivers' calling and effectiveness and partial mediation effect between caregivers' calling and efficiency. Based on this, we discussed the need to improve efficiency through job satisfaction management and to manage efficiency by managing job satisfaction and vocation awareness.

In this study, factors affecting the efficacy of EV charging infrastructure improvement were investigated for EV users on Jeju Island. This study analyzed satisfaction with the EV charging infrastructure and demographic factors that affect the efficacy of EV charging infrastructure improvement. Factors found to affect the efficacy of EV charging infrastructure improvement include a sufficient number of charger installations, the speed in using EV chargers, the ease of obtaining additional information about charging, and fast customer service for faulty chargers. It was also confirmed that demographic factors such as user's housing types had a significant effect. This study contributes to verifying user satisfaction with the construction of EV charging infrastructure throughout Jeju Island.

수요증가 지속과 에너지 산업 구조개편에 따른 발전용 수요의 수급조절역할의 축소로 인해 도시가스 수요 관리에 대한 필요성이 높아지고 있다. 이에 본 연구에서는 도시가스 수료관리를 몇가지 유형으로 분류하고 각 유형별로 가스부문투자(LNG 저장설비소요)에 미치는 영향을 분석할 수 있는 모델을 제시하고 그 검증을 통해 향후 도시가스 수요 관리 시행전략의 수립방향을 제시하고자 한다. 수요관리별 개별효과를 비교하면 동일한 목표율일 경우 최대수요억제가 가장 효과적인 것으로 검증되었으며, 적은 수요물량조정으로 큰 효과를 나타내는 수요관리 유형은 기저부하증대였다. 또한 수요관리전략을 복합하여 시행할 경우, 기저부하증대는 다른 수요관리수단과 같이 실시하여 더 큰 감축효과를 가져왔으나, 전략적 부하창출과 최대수요억제를 동시에 시행하면 그 효과가 상쇄되는 것으로 나타났다. 결론적으로 기저부하증대를 기본으로 하여 전략적 부하창출과 최대수여억제 조치를 시간적인 차이를 두고 시행하는 것이 좀더 효과적일 것으로 검증되었다.
