We tried to do research on main views(risk and knowledge-based) and propose user knowledge as a factor to be managed in order to strengthen the performance. This study empirically analyzed the user-related and project management risk that affect the IT project performance, and verified user knowledge as a moderating variable. The survey was conducted for respondents who have experience on IT Project of public sector and data were analyzed by Smart PLS 3.0. The results show that low user-related and project management risks have a positive effect on performance. In addition, user knowledge has been shown to enhance the impact of two risks on performance. These findings are meaningful in that they emphasize the importance of user knowledge in public-sector IT projects, as well as the repeated verification of integrated research results.

This study is to draw out factors affecting job stress and its effects on their turnover rate as it considers Job satisfaction, organization commitment. In this study, survey have been conducted targeting 124 personnel in National Police Agency and then the collected data were analyzed by using Smart PLS 3.0. This study have proved that causal relationship between job stress, satisfaction, commitment and job turnover respectively which is borrowed from organizational concepts. There will be theoretical and practical contribution to improve work circumstance and secure digital forensic talents as well.

This study sought to examine the impact relationship of the mediated effects of organizational justice on the effects of workplace bullying on turnover intentions. The research hypothesis was verified using SPSS 24 and smartPLS 3 by analyzing 400 surveys of small and medium enterprise workers. Studies have shown that increasing bullying in the workplace also increases emotional depletion and turnover intentions. Emotional depletion has been shown to significantly mediate the impact relationship between workplace bullying and turnover intentions, and organizational justice has laid a theoretical foundation for significantly moderating the impact relationship between workplace bullying and emotional depletion. Therefore, it presented practical implications to increase competitiveness through the well-being and growth of individuals and businesses by increasing respect and sensitivity for workers through compulsory bullying prevention education and various programs. Future research requires research using various variables to prevent bullying.

In this paper, the security behaviors and attitudes related with the personal information of teenagers were investigated using empirical data based on rational behavior theory and protection motivation theory. An experiment for teenagers was conducted on Excel and the statistical packages (i.e., SPSS 21.0 and SmartPLS2.0.M3) to see how self-efficiency, security attitude, security intention and individual innovation affect their security behaviors. The experimental results showed that the security behaviors and attitudes of teenagers between internet and information devices are closely related, and the social influences can affect personal self-efficacy and security attitudes. Finally, we can know that teenagers should recognize the importance of security and protect their personal information safely through continuous education and training so that they can be linked to security behaviors.

This study tried to examine the relationship between superior leadership and emotional support from co-workers on task performance through performance evaluation fairness and self-efficacy in order to find factors that affect the task performance of a company in an uncertain market environment. For this purpose, 500 copies of questionnaire data were collected from corporate employees, and the research hypothesis was verified using Smart PLS 3.0. As a result of the study, superior leadership and emotional support from co-workers showed a positive (+) effect individually on the fairness of employee performance evaluation, Performance evaluation fairness showed a positive (+) effect on self-efficacy. Through this study, it was found that the fairness and self-efficacy of the performance evaluation accepted by employees affects work performance, providing a theoretical foundation for subsequent researchers. Practical implications are suggested to inspire employees to take on a challenge by managing them properly. In future research, based on the results of this study, various studies are needed on the factors that an organization must have for task performance.

This study examined significant differences in the impact of workplace bullying on emotional depletion and organizational commitment, and used 400 questionnaires to examine whether there would be significant differences depending on social support. As an analysis method, we used SPSS 24 for sample characteristics, SmartPLS 3 statistical programs for verifiable factor analysis, reliability and validity, path analysis, and structural equation models. Studies have shown that bullying in the workplace affects significant positive (+) for emotional depletion, and that emotional depletion affects significant negative (-) for tissue commitment. The influence relationship between workplace bullying and tissue commitment was partially mediated in the direction of wealth (-), and the effect of emotional depletion on tissue immersion was shown to be significant differences in the control of social support. Implications are that bullying in the workplace affects emotional depletion, so corporate efforts to prevent bullying are urgently needed, suggesting that employees can improve their organizational commitment, by using a system or community that can promote communication with their bosses.

Most of the preceding studies related to Internet Primary banks are studies on laws, regulations, and expected effects of introduction, and studies on financial consumers' intention to switch to financial services are insufficient. Apply to the PPM(Push-Pull-Mooring)theory to find out the factors that influence financial consumers' intention to switch services from commercial banks to Internet Primary banks. A survey was conducted service users, 1st-order and 2nd-order factor analysis were performed using Smart PLS 3.0. As a result, it was confirmed that the Pull, Push and Mooring had a positive (+) effect on the Intention to Switch, and the Mooring, which is a moderating variable, did not have a moderating effect on the Intention to Switch of the Push and the Pull. The scope of application of the PPM theory, which was used in the service conversion research, was extended to Fintech services, and it can provide various practical useful implications, such as the strategy and spread of Internet Primary banks, and it will be used in various studies to study consumer attitudes.

This study tried to identify the key success factors of ABC by identifying the influence of ABC's success factors on project performance and analyzing the moderating effect of communication. For this purpose, factors applicable to construction projects were extracted through case studies related to the success factors of ABC, an activity-based financial management technique. The survey method was conducted as an online survey method using the Delphi method. For statistical analysis, frequency analysis and factor analysis were performed with SPSS Statistic 20, and hypothesis testing was performed with SmartPLS 2.0. As a result of the analysis, it was found that linkage with quality initiatives affects not only ABC's success factors on project performance, but also communication moderation effects. It was confirmed that linkage and communication with quality initiatives are the most important key success factors for ABC's success. Based on the results of this study, it is expected that if ABC and quality management are well linked, it will be effective in improving project performance.
