This study investigates the relationship between a founder’s occupational background and the survival rate of technology-based startups, focusing on founders with prior research positions. Utilizing a unique tech-based startup database, the study discovers that startups founded by researchers exhibit a lower survival rate compared to those led by founders with other backgrounds. Nevertheless, prior entrepreneurial experience positively moderates the relationship between a founder’s research experience and startup survival rate, indicating that practical business knowledge can offset the inherent lack of business expertise in a researcher’s background. Moreover, the study reveals that startups established by researchers from large companies have an even lower survival rate, as specialization within large organizations may impede the acquisition of essential management skills. These findings emphasize the importance of developing a diverse skill set for startup success.

Many researchers are interested in the relationship between leaders and their followers, whether in the technology or nontechnology sector. However, the moderating factors of the relationship between leadership types and followers’ performance have been underexplored. This study investigates the moderating role of a leader’s narcissism in the relationship between leadership types (transformational and transactional) and follower performance in technology and nontechnology industries. We analyze the results of a survey of 46 chief executive officers and 205 followers at 46 large companies in Korea, of which 30 are in the technology sector and 16 are in nontechnology industries. The results show that a leader’s narcissism mitigates the positive relationship between transformational leadership and followers’ performance. Moreover, a leader’s narcissism strengthens the negative relationship between transactional leadership and followers’ performance. When industry type is considered, this effect remains evident only in the technology sector. These findings suggest that the moderating role of narcissism in the relationship between leadership and follower outcomes can be industry-specific. The results contribute to theoretical discussions about the relationship between leadership types and followers’ performance and its moderating factors.

Medical skill education has been scaled down due to the COVID-19 pandemic. In particular, the decrease in CPR skill training has caused the quality of medical services to deteriorate. While new online education methods have emerged, few studies exist on online teaching and its effects. Since the online teaching of medical skills presents several challenges for instructors, it has not been as effective as face-to-face training. This study designed a new remote system focusing on medical skill education. The proposed video-based application prototype uses an IoT device to measure CPR performance metrics and provides real-time data to users. It was tested using the Kano model on a small group of subjects. The effects of skill training were analyzed quantitatively and qualitatively. A comparative analysis of the remote group and face-to-face group revealed similar average values for appropriate compression depth. In other categories, the remote group fared poorer than the face-to-face group. Considering the high scores given to system usability in the USE survey, remote education shows promise as an alternative to face-to-face education. The significance of this study lies in being the first to develop and test a remote education system for medical skill training in the age of COVID-19.

During technological shifts in which new technology threatens to substitute for existing technology, how do firms search for such new technology? Although several studies have demonstrated the benefits of collaboration among firms in the development of new technologies, research in this stream has largely overlooked the potential roles of competition. Our empirical analysis of U.S. pharmaceutical firms’ adoption of artificial intelligence in 2000–2019 shows that early and late entrants learn from each other. Specifically, late entrants learn basic technology from early entrants, and early entrants learn applied technology from late entrants.
