In the era of the internet and ubiquitous computing, IS users are still facing a variety of threats. Therefore, a need of more tightened information security service increases unprecedentedly. In this sense, this study is aimed at proposing a new research model in which IT assets (i.e., network, system, and information influence) Security and Information Security Service (i.e., confidentiality, integrity, nonrepudiation, authentication) affect information security quality positively, leading to users' satisfaction eventually. To prove the validity of the proposed research model, PLS analysis is applied with valid 177 questionnaires. Results reveal that both IT assets Security and Information Security Service influence informations security qualify positively, and user satisfaction as well. From the results, it can be concluded that Korean government's recent orchestrated efforts to boost the IT assets Security and Information Security Service helped great improve the information security quality and user satisfaction.

Purpose The purpose of this study is to investigate the factors that affect the user satisfaction and continuous use intention of the improved ATCIS in the Korean Army. Design/methodology/approach Based on the various theories in relation to IT continuance, user satisfaction was identified as the main factor with regard to the continuous use intention of the improved ATCIS. In addition, computer self-efficacy, education-training, and system quality were hypothesized as antecedent variables to user satisfaction, and information security stress was set as a moderating variable for these relationships. Findings Survey results show that computer self-efficacy, education and training, and system quality had a positive effect on user satisfaction, and information security stress was found to moderate these relationships. The effects of computer self-efficacy and education-training on user satisfaction were higher in the group with low information security stress. However, the relationship between system quality and user satisfaction was higher in the group with high information security stress. User satisfaction is found to have a positive effect on the continuous use intention even with habit considered as a control variable.

This study explored the performance factors of casino information systems for foreigners, empirically examined the causal relation between these factors and the business performances through organizational trust and job satisfaction and suggested a direction to enhance the casino information systems. The result of this study showed that, firstly, information quality impacted positively on security reliability and job satisfaction. Secondly, system quality impacted positively on security reliability and job satisfaction. Thirdly, service quality impacted positively on security reliability and job satisfaction. Fourthly, security reliability impacted positively on job satisfaction through security reliability. Lastly, security reliability and job satisfaction impacted positively on business performance. This research must be continued by expanding upon the variables of this research study, and there is a need for follow up research on methods that can analyze the management performance of casino information systems from a diverse set of approaches and also research that conducts an analysis on systems that are implemented to prevent tax evasion.

This study explores performance factors of a casino information system for foreigners, empirically examines the causal relation between these factors and business performances through organizational trust and job satisfaction and suggests a plan to develop such a information system. We found that information quality positively impacted on perception of information security, but negatively on job satisfaction; system quality positively did on security reliability, but negatively on job satisfaction; service quality positively did on trust in information security and job satisfaction; lastly security reliability positively did on job satisfaction. We found that information quality, system quality and service quality would affect perceived information security and job satisfaction.

The purpose of this study is to empirically verify the relationship of how job stress and job satisfaction of information security professionals affect turnover intention, a precursor of actual turnover. The moderation effect of organizational justice is also explored within these causal relationships. This empirical analysis used 150 responses from information security professionals within 4 different industries. The analysis result from survey responses shows that job stress increases turnover intention, and job satisfaction decreases turnover intention, and that interactional justice, a subordinate concept of organizational justice, has a negative moderating effect at the relationship between job stress and turnover intention. The moderating effect of interactional justice, which can reduce turnover intention with warm words from managers or colleagues even when information security professionals who respond to emergencies such massive incidents are with high job stress, is a piece of important knowledge for information security managers. To reduce voluntary turnover of information security professionals from the organizational perspective, making efforts to lower job stress and raise job satisfaction and interactional justice is necessary.

Recently, interest in ChatGPT has been increasing. This study investigated the factors influencing the satisfaction of users using ChatGPT service, a chatbot system based on artificial intelligence technology. This paper empirically analyzed causality between the four major factors of service quality, system quality, information quality, and security as independent variables and user satisfaction of ChatGPT as dependent variable. In addition, the mediating effect of reliability between the independent variables and user's satisfaction was analyzed. As a result of this research, except for information quality, among the quality factors, security and reliability had a positive causality with use satisfaction. Reliability played a mediating role between quality factors, security, and user satisfaction. However, among quality factors, the mediating effect of reliability between service quality and user's satisfaction was not significant. In conclusion, in order to increase user satisfaction with new technology-based services, it is important to create trust among users. The research results sought to emphasize the importance of user trust in establishing development and operation strategies for artificial intelligence systems, including ChatGPT.
