  • The supply chain management (SCM) systems have emerged as strong managerial tools for manufacturing firms in enhancing competitive strength. Despite of large investments in the SCM systems, many companies are not fully realizing the promised benefits from the systems. A review of literature on adoption, implementation and success factor of IOS (inter-organization systems), EDI (electronic data interchange) systems, shows that this issue has been examined from multiple theoretic perspectives. And many researchers have attempted to identify the factors which influence the success of system implementation. However, the existing studies have two drawbacks in revealing the determinants of systems implementation success. First, previous researches raise questions as to the appropriateness of research subjects selected. Most SCM systems are operating in the form of private industrial networks, where the participants of the systems consist of two distinct groups: focus companies and vendors. The focus companies are the primary actors in developing and operating the systems, while vendors are passive participants which are connected to the system in order to supply raw materials and parts to the focus companies. Under the circumstance, there are three ways in selecting the research subjects; focus companies only, vendors only, or two parties grouped together. It is hard to find researches that use the focus companies exclusively as the subjects probably due to the insufficient sample size for statistic analysis. Most researches have been conducted using the data collected from both groups. We argue that the SCM success factors cannot be correctly indentified in this case. The focus companies and the vendors are in different positions in many areas regarding the system implementation: firm size, managerial resources, bargaining power, organizational maturity, and etc. There are no obvious reasons to believe that the success factors of the two groups are identical. Grouping the two groups also raises questions on measuring the system success. The benefits from utilizing the systems may not be commonly distributed to the two groups. One group's benefits might be realized at the expenses of the other group considering the situation where vendors participating in SCM systems are under continuous pressures from the focus companies with respect to prices, quality, and delivery time. Therefore, by combining the system outcomes of both groups we cannot measure the system benefits obtained by each group correctly. Second, the measures of system success adopted in the previous researches have shortcoming in measuring the SCM success. User satisfaction, system utilization, and user attitudes toward the systems are most commonly used success measures in the existing studies. These measures have been developed as proxy variables in the studies of decision support systems (DSS) where the contribution of the systems to the organization performance is very difficult to measure. Unlike the DSS, the SCM systems have more specific goals, such as cost saving, inventory reduction, quality improvement, rapid time, and higher customer service. We maintain that more specific measures can be developed instead of proxy variables in order to measure the system benefits correctly. The purpose of this study is to find the determinants of SCM systems success in the perspective of vendor companies. In developing the research model, we have focused on selecting the success factors appropriate for the vendors through reviewing past researches and on developing more accurate success measures. The variables can be classified into following: technological, organizational, and environmental factors on the basis of TOE (Technology-Organization-Environment) framework. The model consists of three independent variables (competition intensity, top management support, and information system maturity), one mediating variable (collaboration), one moderating variable (government support), and a dependent variable (system success). The systems success measures have been developed to reflect the operational benefits of the SCM systems; improvement in planning and analysis capabilities, faster throughput, cost reduction, task integration, and improved product and customer service. The model has been validated using the survey data collected from 122 vendors participating in the SCM systems in Korea. To test for mediation, one should estimate the hierarchical regression analysis on the collaboration. And moderating effect analysis should estimate the moderated multiple regression, examines the effect of the government support. The result shows that information system maturity and top management support are the most important determinants of SCM system success. Supply chain technologies that standardize data formats and enhance information sharing may be adopted by supply chain leader organization because of the influence of focal company in the private industrial networks in order to streamline transactions and improve inter-organization communication. Specially, the need to develop and sustain an information system maturity will provide the focus and purpose to successfully overcome information system obstacles and resistance to innovation diffusion within the supply chain network organization. The support of top management will help focus efforts toward the realization of inter-organizational benefits and lend credibility to functional managers responsible for its implementation. The active involvement, vision, and direction of high level executives provide the impetus needed to sustain the implementation of SCM. The quality of collaboration relationships also is positively related to outcome variable. Collaboration variable is found to have a mediation effect between on influencing factors and implementation success. Higher levels of inter-organizational collaboration behaviors such as shared planning and flexibility in coordinating activities were found to be strongly linked to the vendors trust in the supply chain network. Government support moderates the effect of the IS maturity, competitive intensity, top management support on collaboration and implementation success of SCM. In general, the vendor companies face substantially greater risks in SCM implementation than the larger companies do because of severe constraints on financial and human resources and limited education on SCM systems. Besides resources, Vendors generally lack computer experience and do not have sufficient internal SCM expertise. For these reasons, government supports may establish requirements for firms doing business with the government or provide incentives to adopt, implementation SCM or practices. Government support provides significant improvements in implementation success of SCM when IS maturity, competitive intensity, top management support and collaboration are low. The environmental characteristic of competition intensity has no direct effect on vendor perspective of SCM system success. But, vendors facing above average competition intensity will have a greater need for changing technology. This suggests that companies trying to implement SCM systems should set up compatible supply chain networks and a high-quality collaboration relationship for implementation and performance.

  • Untact marketing is being activated due to COVID-19. As a result, live commerce, an untact seller, is also active in the e-commerce market. Therefore, in this study, we tried to find out what factors influence consumers when they purchase through live commerce. In particular, since consumers' trust and flow in live commerce platforms and products is important, their mediating effects were analyzed. The research model was established by deriving common variables among the characteristics of live commerce based on previous studies. An online survey was conducted for empirical analysis. 200 users who made at least one purchase in live commerce were analyzed. The study results are as follows. Among the characteristics of live commerce, entertainment, economics, professionality were found to have a positive (+) effect on purchase intention. On the other hand, ease of use did not significantly affect purchase intention. The influence was shown in the order of entertainment, professionality and economics. The mediating effect of trust was found to play a mediating role in that entertainment, economics, and professionality affect purchase intention. On the other hand, a significant mediating effect was not tested between ease of use and purchase intention. As for the mediating effect of flow, it was found that flow plays a mediating role in that entertainment and economics affect purchase intention. On the other hand, the mediating effect of flow in terms of ease of use and economics affecting purchase intention was not tested. As for the multiple mediating effect of flow and trust, the mediating effect of flow was stronger than the mediating effect of trust when entertainment had an effect on purchase intention. In terms of professionality affecting purchase intention, the mediating effect of flow was also stronger than the mediating effect of trust. On the other hand, it was analyzed that only trust had a mediating effect when economics had an effect on purchase intention. The results of this study empirically tested that entertainment, which is a fun and interesting factor of live commerce content, is the most important factor when consumers use live commerce. In addition, various results were derived, such as cases where trust and flow act as mediators at the same time or not at all. Practical implications can be found in that it provided a clue about what to prioritize in order to reach consumers for live commerce platform.

  • The purpose of this study is to investigate the effect of toddler's emotionality and mother's reaction to their child's negative emotions of social-emotional behaviors of toddlers. The subjects were 141 mothers and toddlers ranging in age from 18 to 36 months. Instruments used in this study were: 1) Early Childhood Behavior Questionnaire(ECBQ)(Rothbart, 1994), 2) Coping with Toddlers' Negative Emotions Scale(CTNES)(Eisenberg et al., 1996), and 3)Brief Infant Toddler Social and Emotional Assesment(BITSEA)(Carter et al., 2006). Data were analyzed using Pearson's correlation and hierarchical multiple regression analysis. The results of this study show that toddler's emotionality and the mother's negative reaction to their child's negative emotions were related to the social-emotional behaviors of toddler. Also, mother's reaction to their child's negative emotions have mediation effects between toddler's emotionality and social-emotional behaviors. Specifically, toddler's emotionality has a partial mediating effect on social-emotional behaviors through mother's supportive reaction to their child's negative emotions. Additionally it was also determined that the toddler's emotionality has a complete mediating effect on the relationship between mother's unsupportive reaction to their child's negative emotions and the social-emotional behaviors of toddler. Theses results support the notion that mother's character as well as child's personality at birth are critical predictors which could impact social-emotional behaviors of toddler.

  • The physical computing education, as the emerging field, is a form of education that helps learners to develop the attitude of scientific inquiry by developing meaningful and creative output through the integration of hardware and software elements. Based on the literature, the authors of the study used science experience, school support and learning flow as the variables that predict the outcome variable which is the attitude of scientific inquiry. The authors collected data from 64 fourth and sixth graders who studied physical computing at an institution for the gifted and talented in Korea and then analyzed them using descriptive statistics, correlation, multiple regression and simple mediation analysis methods. As a result, science experience and learning flow significantly predicted the attitude of scientific inquiry. In addition, learning flow mediated the relationship between science experience and the attitude of scientific inquiry, and the relationship between school support and the attitude of scientific inquiry. Based on these results, the authors propose that to promote the attitude of scientific inquiry in physical computing education, strategies must be implemented for improving science experience, school support and learning flow in instructional design.

  • The ICT policy domain is one of the most important policy domains in terms of national development and continuity. It is primarily because the contemporary society has been continuously developed and changed based upon the advanced information technologies. Recently, the Moon Jae-in Administration reorganized the Ministry of Science and ICT, and transferred a few of the key ICT related functions to other ministries as an attempt to develop the national ICT policies. However, critics in this domain argue that various problems still exist in the ICT policies in Korea. Therefore, the purpose of this research is to verify the empirical validity of the existing problems in the ICT policies in Korea, and develop alternatives to solve those problems. In order to serve the research purpose, this study employs multiple methods; a quantitative method which is a survey involving experts in ICT policies, and a social network analysis involving public officials in ICT related ministries. Research results show that the Korean government needs to enhance its capacity to make adjustments in ICT-related policies as the current decentralized system continuously creates various types of problems. The second possible solution to the problem is to change the national ICT policy system to a centralized one. However, this requires various efforts such as cooperation among ICT related government agencies, separation of ICT policies from science and technology policies, and increased government capacity to implement the ICT policies.

  • The purpose of this study was to investigate the moderating mediation effect of resilience, on the relationship between emotional intelligence and self-efficacy in career decision-making of nursing students. The participants were 136 nursing college students in the Jeonbuk region. Data was collected in September 2020 via a structured questionnaire survey. The data was analyzed using the SPSS/23.0 program. The analysis used descriptive statistics, Pearson's correlation coefficient, independent t-test, one-way ANOVA, multiple regression analysis, and Sobel's tests. The results showed that emotional intelligence was a circle activity (F=3.13, p=.047), and motivation to nursing (F=4.16, p=.008). Resilience was a circle activity (F=5.50, p=.005), and nursing major satisfaction (t=2.19, p=.031). Career decision-making self-efficacy showed significant differences in grade (F=3.12, p=.048) and major satisfaction (t=2.36, p=.020). Emotional intelligence and resilience (r=.63, p<.001), emotional intelligence and career decision-making self-efficacy (r=.67, p<.001), resilience and career decision-making self-efficacy (r=.76, p<.001) showed significant static correlation. In emotional intelligence and career decision-making self-efficacy, resilience had a partial mediating effect (Z=6.48, p<.001), and explanatory power was 62.2%. Based on the results of this study, to improve the emotional intelligence and career decision-making self-efficacy of nursing students, it is necessary to develop a personalized and resilience-enhanced education program.

  • This study was conducted to investigate the mediating effects of coping on the impact of life stress on depression, subjective well-being and psychological well-being in nursing students. Self-report questionnaires were used to collect data from 147 nursing students. Data were analyzed using descriptive statistics, Pearson's correlation coefficient and hierarchical multiple regression. Nursing students who had a higher level of depression had a higher level of life stress, as well as a higher frequency of avoidance coping. Conversely, those who had a higher level of subjective well-being and psychological well-being had a lower level of life stress, as well as a lower frequency of avoidance coping. There were also significant positive correlations between psychological well-being and problem solving coping. The results showed that avoidance coping partially mediated the effects of life stress on depression, subjective well-being and psychological well-being. The results suggest that it is necessary to offer stress management programs to reduce avoidance coping, with additional consideration of life stress and coping strategies, to prevent depression and improve well-being among nursing students.

  • Purpose - This study is to clarify the structural relationship between the direct supervisor and organizational commitment and organizational citizenship behavior through mediation of the Leader-member exchange (LMX) in the hospital organization, and to confirm the mediating effect of the LMX. Through this study, we will provide basic data on the aspects of HR to enhance organizational immersion and organizational civic behavior in hospital organizations, and present suggestions on academic contribution and effective organizational operation measures. Research design, data, and methodology - This study is to investigate the relationship between authentic leadership and OC and OCB of the organization member, which is proposed to secure more active and high competitiveness in the recent changing medical environment, with multi-regression and B&K(1986) method. For this purpose, 653 employees of senior hospitals in Seoul and Kyeong-In area were surveyed using structured questionnaires. Each questionnaire was composed of 7-point scale, and each hypothesis was testified by multiple leaner regression and by BK method for testifying mediator effect. Result - As a result of the analysis, it was found that the male and non-medical staff had higher recognition level than the medical staff in the LMX, organizational commitment and organizational citizenship behavior. In the senior management or more than 5 years' experience group, organizational commitment and organizational citizenship behavior were recognized higher than the group of subordinate managers. Second, authentic leadership has a positive influence on LMX, organizational commitment and organizational citizenship behavior, and LMX has a significant positive impact on organizational commitment and organizational citizenship behavior. In addition, as a result of analyzing LMX mediating effect in the relationship of authentic leadership and organizational effectiveness by BK method, LMX had partial mediating effects between authentic leadership and organizational citizenship behavior, and between authentic leadership and organizational commitment. Conclusion - Results of the study confirmed that all the members of the hospital organization that were lacking served as positive factors for the relationships of authentic leadership and LMX, and authentic leadership and organizational effectiveness. It is expected that the hospital organization will be able to suggest such as the organizational approach to expect high organizational effectiveness centering on authentic leadership ability as psychological capital.

  • This study was carried out to examine the converging factors related to academic burnout in students from health-related majors who are involved in studying for the Test of English for International Communication (TOEIC). Research subjects included 291 randomly selected students from the J-region, who were enrolled in TOEIC classes. Data collection took place from April 3, 2017 to April 14, 2017, using anonymous self-administered questionnaires. The results of a multiple regression analysis in female students showed higher academic burnout pertaining to studying for the TOEIC when sleeping hours, self-worth, self-efficacy, school adaptation resilience, and study immersion were low, and job-seeking stress and test anxiety were high. The explanatory power of this model was 65%. Based on these results, to reduce academic burnout pertaining to studying for the TOEIC in health majors, it is first necessary to increase sleeping hours, self-worth, self-efficacy, school adaptation resilience, and study immersion, and to make efforts to manage self-competence, job-seeking stress, and test anxiety. The results of this study may be used to decrease the academic burnout caused by studying for the TOEIC in health major students and to increase their aptitude for studying English, to cultivate globalized capabilities. Future studies need to conduct an effect analysis on the control and mediation effect that these factors have on academic burnout.
