The purpose of this study is to enhance an understanding of employee's OCB(organizational citizenship behavior) in manufacturing innovations like a TPM(total productive maintenance). OCB is examined as a dependent variable in three dimensions; compliance behavior, altruistic behavior, and innovative behavior. The six determinants of OCB are considered based on previous literature : organizational culture, team climate, transactional leadership, transformational leadership, job satisfaction, and organizational commitment. And the moderating effect of TPM on the relationships between OCB and determinants are examined. Data is collected through questionnaires and interviews from 684 employees in the Korean medium-sized manufacturing company that are conducting TPM. The result indicates that the important influencing factors of OCB are team climate, organizational culture, and job satisfaction. And the moderating effect of TPM on the relationships between OCB and job satisfaction is founded.

Dual-cooled annular fuel allows a significant increase in power density while maintaining or improving safety margins. However, the dual-cooled design brings much higher Zircaloy charge in reactor core, which could cause a great threaten of hydrogen explosion during severe accidents. Hence, an innovative fuel combined dual-cooled annular geometry and SiC cladding was proposed for the first time in this study. Capabilities of fuel design and behavior simulation were developed for this new fuel by the upgrade of FROBA-ANNULAR code. Considering characteristics of both SiC cladding and dual-cooled annular geometry, the basic fuel design was proposed and preliminary proved to be feasible. After that, a design optimization study was conducted, and the optimal values of as-fabricated plenum pressure and gas gap sizes were obtained. Finally, the performance simulation of the new fuel was carried out with the full consideration of realistic operation conditions. Results indicate that in addition to possessing advantages of both dual-cooled annular fuel and accident tolerant cladding at the same time, this innovative fuel could overcome the brittle failure issue of SiC induced by pellet-cladding interaction.

From the past to the present, justice has attracted many people's attention. Most of the previous studies carried out in relation to justice are studies of the resulting variables, and there is a great advantage that they let us know about the importance of justice. However, the findings are focused only on the behavior of the members of the organization according to the status of justice already perceived. Therefore, studies on the antecedent of justice are also necessary to understand justice accurately. This study identifies the factors that can directly affect justice and the contextual factors that could moderate their relationship. In particular, using the '2017 Public Employee Perception Survey' released by the Korea Institute of Public Administration, we examined how innovative behavior of public employees affects the perception of distributive justice and how the relative professionalism, which is the situation variable, moderates the relationship between variables. A regression analysis of 321 public employees showed that innovative behavior affects the perception of distributive justice, and that the positive relationship of innovation behavior to the perception of distributive justice is weakened when the level of individual perceived relative professionalism is high.

The purpose of this study is to examine the mediating effect of organizational commitment in the relationship between transformational and transactional leadership and innovative behavior and demonstrate the moderated mediating effect of job satisfaction. To this end, 4,133 cases from the 『2021 Public Servant Life Survey』 conducted to general public servants belonging to central administrative agencies and metropolitan governments by the Korea Institute of Public Administration were used for the analysis, and SPSS 21.0 and Mplus 8.4 programs were used to test the research hypotheses. As a result of the analysis, it was confirmed that transformational and transactional leadership had a positive effect on organizational commitment and innovative behavior, and organizational commitment had a positive effect on innovative behavior. In addition, it was confirmed to have a significant mediating effect in the relationship between transformational and transactional leadership and innovative behavior. Finally, it was confirmed that the mediating effect of transformational and transactional leadership on innovative behavior through organizational commitment was moderated by the level of job satisfaction, and all the proposed hypotheses were adopted. Based on theses findings, theoretical and practical suggestions and future research suggestions were discussed.

This study first presents the characteristics of emerging leadership researches by theoretically analyzing the studies related to leadership since the Millenium. The first finding is that most of leadership researches shared same if not similar aspects of transformational leadership. Secondly, much of leadership researches centered around horizonally expanded shared/distributed leadership. Thus, this researches analyzed the effectiveness of the shared/distributed leadership theory based on previous researches and found shared/distributed leadership has positive impact on member's recognized performance and innovative behavior. However, in competition-oriented culture, shared/distributed leadership did not control recognized performance of its members. This implies the demand for shared/distributed leadership is necessary today and research on the matter will expanded globally but, the results may differ according to the cultural value of the company.

Background: This study aimed to investigate whether there is a difference in organizational member attitudes by workplace environment and workplace types in dental hygienists working at dental health centers. Methods: A face-to-face survey or online survey was administered to dental hygienists working at dental health centers, and a total of 95 subjects were included. The survey includes 13 items to ask factors affecting employee's job satisfaction. Also, some questions were included to assess perception of organizational member attitude: five about organizational citizenship behavior, two about innovative behavior, and four about organizational commitment. Results: Dental hygienists working at dental clinics were more satisfied with their incomes and numbers of working days, while those from dental university hospitals and general hospitals were more satisfied with education support. In addition, hygienists working at dental hospitals were more satisfied with job autonomy, individual work capability, safe working environment, personal relation, potential for personal development, and positive labor-management relations, compared to those working at general and university hospitals (p<0.05). Among the items about perception of organizational member attitudes, the scores of items about organizational citizenship behaviors were higher, whereas the scores of items about innovative behaviors were relatively lower. Individuals working at dental hospitals than those working at general and university hospitals, chiefs and team and department leaders than team members, and those with increased satisfaction with current workplace had more positive perception of organizational member attitudes. Conclusion: For dental hygienists to have positive attitudes as organizational members, working environment should be improved, and executives of dental healthcare centers should pay attention to improving job satisfaction of organizational members. Moreover, since dental hygienists need to improve their perception of innovative behaviors and citizenship behaviors to strengthen specialty of dental hygienists in a changing dental healthcare, relevant training should be addressed in refresher courses or school programs.

The purpose of this study is to confirm the mediating effect of followership characteristics when the components of transformational leadership influences the innovative behavior of follower. For this study, response data of nationwide 551 workers were finally analyzed using SPSS 24 and Process Macro 3.5. The research results are as follows. All of the components of transformational leadership had a positive(+) effect on innovative behavior. In this process, team spirit, the characteristic of followership, was confirmed to have a mediating effect in all relationships. Perception of goal alignment and active orientation were found to have mediating effects in some types of combination. On the other hand, critical thinking had no mediating effect. This study has academic significance that variables with complex characteristics were divided into sub-characteristics for analyzing. In practice, it is suggested that there is an effective combination type for each characteristic of the variables in promoting the innovative behavior of follower. Based on the research results, the limitations of the research and future research tasks were presented.
