In this study, we examined the effect of shared leadership on organizational trust, knowledge sharing, and innovative behavior. Also, it was verified that organizational trust and knowledge sharing play a mediating role in the relationship between shared leadership and innovative behavior. Data were collected from a survey of 348 manufacturing workers in Ulsan and Gyeongju. SPSS 22 was used for frequency analysis and exploratory factor analysis. AMOS 22 was used for confirmatory factor analysis to verify the validity of the variables and for covariance structure analysis to verify the research hypothesis. The results of this study are as follows. First, shared leadership has a significant positive effect on organizational trust, knowledge sharing, innovative behavior. Second, organizational trust has a significant positive effect on knowledge sharing and innovative behavior. Third, knowledge sharing has a significant positive effect on innovative behavior.

This study examined the effects of the R&D project managers' leadership on the product development performance. A survey was carried out empirically on a group of 175 experts associated with project management R&D operations in the field of manufacturing, construction engineering, shipbuilding, plant, and IT. The survey results showed that the effects of the R&D project managers' leadership on the product development performance were not significant, and the mediating effects of the project sponsor roles were significant. This means that the leadership of leaders, which requires efficient control and management based on complicated intergroup relationships and roles, is important in a project involving experts from the professional field. This suggests that the efficient leadership of leaders can improve the performance through the cooperation of members in the organization and aggregation of their core competencies in a limited time. Overall, the key results of this study mean that project leaders should play an active mediating role to maximize their leadership and enhance the role of project sponsors. In addition, the mediating role of project sponsors has an effect on the leadership of project managers, affecting the project performance quality.

This study was conducted focusing on the innovative behavior necessary for the long-term survival of an organization in a business environment in which uncertainty and complexity are increasing. To this end, the relationship between issue leadership and innovative behavior of organizational members was investigated from the perspective of Signaling theory, Path-Goal theory and Job Demands-Resources theory. In addition, the mediating role of learning agility and sub-components of learning agility was empirically analyzed. For empirical analysis, a survey was conducted with a total of 252 team leaders and team members working in multinational companies (142 in Korea, 110 in the US). The results of this study are as follows. Issue leadership was analyzed to have a positive (+) effect on the innovative behavior of employees. Learning agility was found to play a mediating role between issue leadership and innovative behavior. On the other hand, the mediating effect was tested for each of the sub-components of learning agility, such as feedback seeking, information seeking, reflecting, experimenting, agility. As a result, all five sub-components were found to play a mediating role between issue leadership and innovative behavior. In particular, it was analyzed that the mediating effect of agility was the largest. Next, information seeking appeared to be large. Although there are some studies that have identified the mediating role of learning agility between issue leadership and innovative behavior, this study is considered to have academic implication as there are few cases of subdivided study. At the practical level, it is expected to provide implications for where to focus more when trying to improve an organization's learning agility and innovation behavior

The survey collected data on general leadership roles such as information roles, decisional role and interpersonal role, as well as on specific Information Technology leadership roles such as planning leader, R&D manager, general manager, chief operating strategist. The role of a change leader is positively influenced by the number of years, the extent of strategic responsibility and the organization's revenue while it is negatively influenced by the number of years in the current position. R&D manager can be predicted by strategic responsibility and chief executive's IT use, Manager can be predicted by the extent of strategic responsibility. Although several significant predictors of Information Technology leadership roles were identified, the more signigicant study should continue in the future.

The organizational effectiveness of hospital in various environmental fluctuations is a large and complex problem. Hospital CEO leadership characteristics may be a critical determinant of employees' job satisfaction and turnover intention. Several empirical studies on transformational leadership found that transformational leadership behaviors were positively related to workers' job satisfaction and turnover intention. Very little research related to this subject has been done in health care settings in Korea. The author explores the relationship between hospital CEO leadership style and its effect on job satisfaction and turnover intention among the all staffs of general hospital. The relationship of hospital CEO leadership style to employees' job satisfaction was investigated using the Bass's leadership paradigm of transformational and transactional leadership. The Multifactor Leadership Questionnaire(MLQ) and the index of job satisfaction and turnover intention were completed by 493 hospital employees(doctors, nurses, hospital administrators, technicians, and assistants). The findings show a similar trend to the previous studies. Hospital CEO leadership behaviors and employee outcomes were significantly correlated. Correlations showed a significant positive relationship between those hospital CEO exhibiting a transformational leadership style and the job satisfaction of their staffs. The results of multiple regression analysis indicate that the effect of charisma in transformational leadership behaviors is more higher than other variables. Transformational leadership style may be a more effective strategy and have a greater effect on staff outcomes, attitudes and behaviors. The findings of this study reveal implications for efficient hospital management and the importance of understanding relationship between hospital CEO's leadership style and subordinate behaviors in the context of CEO's desirable role and function for hospital strategy planning and future direction.

This study examined the effects of perceptual differences of safety leadership between managers and workers on workers' safety attitudes and behavior in two construction sites. In addition, the mediating role of safety attitude between safety leadership and safety behavior across discrepancy level of safety leadership. This study was conducted on two first-tier construction companies within the 100th place in 2019. Two companies were similar in size(100 - 150 billion won) and process from the basement frame finishing stage to start of the ground structure of apartment. In A Site, 40 managers and 73 workers, 42 managers and 77 workers in B site participated the survey on managers' safety leadership, and workers' safety attitude and behavior. The results showed that there was no significant difference between the safety leadership scores assessed by the manager and workers at site B. However, the safety leadership scores assessed by the managers were significantly higher than that by the workers at site A. The workers' safety attitudes and behaviors at site B were higher than those of workers at site A. Moreover, Site B was significantly higher in the effects of safety leadership on safety behavior than Site A. At site B, safety leadership had a significant influence on safety behavior even after controlling the safety attitude of workers. At site A, safety leadership had no significant effect on safety behavior after controlling safety attitude. These findings suggest that there is managers' self-serving bias on safety leadership in site A and that this bias of leadership can negatively affect workers' safety attitude and behaviors. In addition, it can be seen that if the self-serving bias on safety leadership occurs, the manager's safety leadership has less influence on workers' safety behavior.
