The purpose of this study is to investigate whether the job engagement mediates relationship between positive psychological capital and turnover intention in the event worker. For it, a questionnaire survey is performed for 394 participants consisted of male and female living in BUSAN. Their age is from 20 to 50. Afterwards, the collected data is analyzed using the regression analysis. Positive psychological capital is significantly positive to the job engagement. Meanwhile, positive psychological capital is significantly negative to the turnover intention. Likewise, job engagement is significantly negative to the level of turnover intention. Also, job engagement partially mediated relationship between positive psychological capital and turnover intention. Therefore, this study suggests that it will be developed the mediation program that improves both work environment and positive psychological capital to increase job engagement as well as reduce turnover intention in the event worker.

It is an important issue to evaluate the effectiveness of chemical warfare through modeling and simulation(M&S) technology. In this paper, we propose the M&S methodology and environment for the chemical warfare for effectiveness analysis. In detail, for modeling perspective, we propose three fundamental component models according to their behaviors, which are a chemical weapon, a detecting device system, and an engaging unit system. Among proposed models, the chemical weapon and the detecting device system models are represented by engineering-level system models, whereas the engaging unit system model are described as an engagement-level system model. For simulation perspective, we apply a hybrid simulation environment using High Level Architecture (HLA) to interoperate with the proposed engineering and engagement-level models. The proposed M&S methodology and environment enables to evaluate the effectiveness of the chemical warfare system considering the doctrines, the performance of device or weapon, and weather factors. To verify the efficiency of the proposed methodology and environment, we experimented three categorized case studies, which are related with those considering factors.

The purpose of this study is to examine, at the team level, the relationship between shared leadership and team work engagement and team psychological capital which have rarely been introduced into academic leadership research in Korea. This study tested the impact of shared leadership on team work engagement and the mediating role of team psychological capital between the two variables. And also, this study tested moderating role of task characteristics between shared leadership and team psychological capital. A total of 421 employees of 100 teams in 16 companies in South Korea participated in this study. The SPSS 23.0 statistical program was used in this study to analyze and statistically process the collected survey data. The result showed that high level of shared leadership positively influence team work engagement and team PsyCap works as mediator in the relationship between shared leadership and team work engagement. This results means that shared leadership is a crucial factor to facilitate team's psychological capital toward team's work engagement. However, Task characteristics had no moderating effect between shared leadership and team PsyCap. Finally, theoretical and practical implications of the study results have been discussed along with limitations and future direction of the study.

Objectives: A mobile health intervention program was provided for employees with overweight and obesity for 12 weeks, and a process evaluation was completed at the end of the program. We investigated participant engagement based on app usage data, and whether engagement was associated with the degree of satisfaction with the program. Methods: The program involved the use of a dietary coaching app and a wearable device for monitoring physical activity and body composition. A total of 235 employees participated in the program. App usage data were collected from a mobile platform, and a questionnaire survey on process evaluation and needs assessment was conducted during the post-test. Results: The engagement level of the participants decreased over time. Participants in their 40s, high school graduates or lower education, and manufacturing workers showed higher engagement than other age groups, college graduates, and office workers, respectively. The overall satisfaction score was 3.6 out of 5. When participants were categorized into three groups according to their engagement level, the upper group was more satisfied than the lower group. A total of 71.5% of participants answered that they wanted to rejoin or recommend the program, and 71.9% answered that the program was helpful in improving their dietary habits. The most helpful components in the program were diet records and a 1:1 chat with the dietary coach from the dietary coaching app. The barriers to improving dietary habits included company dinners, special occasions, lack of time, and eating out. The workplace dietary management programs were recognized as necessary with a need score of 3.9 out of 5. Conclusions: Participants were generally satisfied with the mobile health intervention program, particularly highly engaged participants. Feedback from a dietary coach was an important factor in increasing satisfaction.

This study holds various implications and usefulness toward nurses as well as hospitals in that the study empirically found out the relations among hospitals' ethical climates, employee engagement (job engagement and organizational engagement) and intention to quit. The study shows that nurses' awareness of principles of responsibilities and benevolent ethical climates impact on enhancing organizational engagement and lowering intention to quit. Internally, employees are encouraged to make decisions accompanying fairness and responsibility and thus, shared values will be created between hospitals and nurses, while it will contribute to create a good image of the hospital to the public. However, it is also revealed that climates deficient in ethics, such as a climate of selfishness, have strong negative influences on workplace attitude of nurses. Therefore, recognizing importance and effectiveness of ethical climates, hospitals should underscore personal ethics of managers and nurses, and should go further to exert strategic efforts on the organizational level to create ethical hospital climates where nurses can naturally take ethical actions.

This study is a descriptive research study to confirm the mediating effect of job engagement on the relationship between the nursing organizational culture and the quality of nursing service perceived by nurses. The research subjects and data were collected from June 1 to June 7, 2022, and 215 nurses working at hospital-level or higher medical institutions recruited through the online community for nurses. As a result of the study, Relation orientated culture(Z=3.88, p<.001) and Task orientated culture(Z=3.16, p=.001) affected the quality of nursing service, and it was found that job engagement fully mediating effect. Hierarchical orientated culture (Z=2.39, p=.017) affected the quality of nursing service, and it was found that job engagement had a partial mediating effect. Therefore, in order to improve the quality of nursing services, it is necessary and to promote work engagement by forming a culture to establish a trust relationship among members based on the order and procedure for safety in nursing sites that require rapid and accurate response in emergency situations and performing tasks efficiently to achieve organizational goals.

An emphasis on public-private partnership (PPP) in the regulatory policy process can overcome the challenges hindering regulatory effectiveness with the emergence of fast developing technologies and new industries. This study attempts to evaluate quantitatively different aspects of institutional settings of South Korean regulatory policy in terms of stakeholder engagement as PPP, using evidence-based data released by the OECD. From the results of the principal component analysis, South Korea can be evaluated as being at a very good level overall in its institutional establishment. Nevertheless, the fact that the outcome of regulatory reforms in South Korea is still insufficient compared with this well-established system suggests that the country should concentrate on improving system operation. Consequently, this study makes policy suggestions to improve regulatory effectiveness through PPP by supplementing the facets that are well-equipped but not feasible with respect to regulatory policy cycle, regulatory governance, regulatory method, and conflict resolution.

High-Level Architecture(HLA)/Run-Time Infrastructure(RTI) are standards for distributed simulation systems and offer a technology to interconnect them and form one single simulation system. In defense domain, M&S is the only way to prove effectiveness of weapon systems except for Live Fire Testing (LFT). This paper focuses on guided missile simulations in weapon systems for engagement analyses and proposes the integrated flying vehicle model that is based on HLA/RTI. There are a lot of missiles in real world; therefore, we should develop each missile models in M&S in order to apply battlefield scenarios. To deal with the difficulties, in this paper, firstly, I classify these missiles into three models: ballastic, cruise, and surface-to-air missile models, and then I design each missile model and integrates them into a single model. This paper also offers a case study with my integrated flying vehicle model. At the conclusion, this paper presents contributions of this paper.

Recently, Korean universities have increased the number of English Medium Instruction (EMI) lectures in order to allow students to gain both specialized knowledge and enhanced English ability. Previous researches on effective EMI lectures have focused on exploring the effects of learners' cognitive and affective characteristics on learning outcomes. Whereas the input variables of learning have been investigated as predicting variables of effects in EMI lectures, there has been a few research for investigating process variables to yield learning outcomes. The purpose of this study is to analyze the structural relationships among variables affecting on learner satisfaction and effects. The participants are 209 engineering students from various majors. Independent variables are defined as English motivation, English competency, and English confidence, a mediated variable is Cognitive engagement, and dependent variables are Learning satisfaction and Educational effect perception. The results show that the relationships are statistically significant: learners' English competency & English confidence ${\rightarrow}$ Cognitive engagement ${\rightarrow}$ Learning satisfaction ${\rightarrow}$ Educational effect perception. Especially, the structural model confirms that the effect of learners' English confidence on Learning satisfaction and Educational effect perception is mediated by the level of learners' Cognitive engagement. Further, the implication for effective EMI lectures is discussed based on the observed research results.

This study examines the potentials of realistic controller and point-of-view to affect users' arousal, valence, identification and engagement. While media researchers have advocated the role of realistic controller and point-of-view as a possible contributor to psychological reactions of playing video game, this claim is based on a relatively small number of empirical studies. Collegiate subjects took part in an experimental investigation manipulation the level of controller realism(gamepad vs. steering wheel) and point-of-view(first person vs. third person). Results of the study showed the influence of controller realism and point-of-view on arousal, identification and engagement, and the implication of the findings are discussed.
