The purpose of this paper was to explore the underlying mechanism of the relationship between psychological safety and performance.

A serial multiple mediation model that explains the impact of psychological safety on performance via job crafting and thriving at work was proposed and tested using PROCESS macro (Model 6). Data were collected from 320 employees at three different large Korean organizations.

The results of this study found that job crafting and thriving at work sequentially mediate the relationship between psychological safety and performance. However, the direct effect of psychological safety on performance was found to be nonsignificant. Put differently, psychological safety is unrelated to performance independent of the effects of job crafting and thriving at work.

The present study theoretically contributes to psychological safety research by proposing and testing a serial mediation model that explores the underlying mechanism of the relationship between psychological safety and performance in detail. Practically, this study informs managers about the importance of ensuring a psychologically safe workplace environment and encouraging employees' proactive behaviors to enhance their performance and ability to thrive at work.

The purpose of this study is to clarify the relationship between two sub-constructs of heavy work investment: work engagement and workaholism.

The authors conducted a systematic review and meta-analysis to synthesize and critically assess existing research on the relationship between these concepts.

The review revealed three major shortcomings of the extant literature: a dichotomous perspective, variations in measurements and the unaddressed complexity of the relationship.

Based on these findings, this study provides a discussion on the limitations and suggestions for future research on work engagement and workaholism, including using a person-centered approach.

The purpose of this paper is to review the existing workplace learning measures used in empirical studies in human resource development (HRD).

By reviewing 141 studies on workplace learning published in six journals in the field of HRD, we identified nine measures for workplace learning. Tynjälä’s (2013) 3-P model of workplace learning was adopted as the framework to analyze the features of each measure in terms of presage, process and product.

Workplace Climate Questionnaire, Learning Opportunities Questionnaire, Approaches to Work Questionnaire and Self-regulated Learning in the Workplace Questionnaire belong to the presage category. Small Business Workplace Learning Survey and Workplace Learning Activities are categorized as the process dimension. The Questionnaire on Informal Workplace Learning Outcomes is in the product dimension. Informal Workplace Learning Survey and Workplace Adaptation Questionnaire are across the three categories.

The authors identified the issues of existing workplace learning measures to emphasize the importance of reliable and valid measures for workplace learning and to gain the attention of researchers concerning these issues.

The findings can provide organizations and practitioners with insights and ideas on how to prepare employees to engage in diverse learning activities, how to support their learning activities and how to combine their learning activities with the existing job structure and work system.

This study is the first to review workplace learning measures in the field of HRD. The authors review the dimensions, items and reliability of each measure, and summarize the features of nine measures in terms of presage, process and product of workplace learning.

The high turnover of new graduate employees has become a concern for many organizations in Korea. This study explores when new graduate employees leave first jobs and what makes these employees decide to leave employees' organizations.

Using national panel data from South Korea, the authors employed a survival analysis and examined the factors that explain the turnover of new graduate employees.

The findings of this study reveal that many new graduate employees leave the employees' organizations within two years. Moreover, work conditions, work satisfaction and job-skill match were associated with new graduate employee turnover.

Based on the results of survival analysis derived from actual turnover data, not turnover intentions, the authors emphasize appropriate human resources (HR) intervention, a working environment and organizational culture, and employee development opportunities.

The purpose of this study is to validate the Korean version of the thriving at work measurement by Porath et al. (2012).

After translating the thriving at work measurement into Korean, the researchers assessed the validity and reliability of the measurement in a Korean working context using two different samples. In Study 1, the study validated the translated measurement using Rasch’s (1960) model, exploratory factor analysis and a reliability test with a sample of 322 employees. In Study 2, the study conducted a confirmatory factor analysis, a reliability test and a convergent and discriminant validity test using a sample of 187 employees.

Based on the analyses, this paper concluded that thriving at work has a two-factor construct and eight-item thriving at work measurement was better than the original 10-item measurement. The eight-item measurement demonstrated good discriminant and convergent validity.

This study validated the thriving at work measurement in a Korean context using Rasch’s (1960) model from the item response theory perspective.

The purpose of this study is to investigate individual and organizational factors that influence the relationship between career development and job performance improvement.

This study adopts multilevel analysis, using the 2013 Human Capital Corporate Panel data set compiled by the Korea Research Institute for Vocational Education and Training.

Taking into consideration 572 employees over 61 companies, our findings reveal that job satisfaction and organizational commitment are significant individual factors that affect job performance through career development. Moreover, mentoring/coaching is found to be an organizational factor that influences job performance improvement through career development, while job rotation interferes with job performance through career development.

The framework of the present study is consistent with the framework for organizational career development created by McDonald and Hite (2016), which emphasizes considering both organizational and individual factors together.

The results of this study provide empirical evidence and practical implications for leaders, line managers and human resource managers who are responsible for employees’ career development when they plan career development interventions.

This study offers a conceptual framework for career development, paying special attention to multi-level development.

The purpose of this paper is to study the conceptual design and optimisation of a compound gyroplane. A study of a compound gyroplane configuration and its characteristics was performed to develop a sizing program.

The vertical takeoff and landing capabilities of a helicopter are particularly important. The need for efficient hover and the effectiveness of forward flight in the helicopter can cause conflicts within the design process. The designers usually wish to increase the helicopter's maximum forward speed. Recently, the compound aircraft is one of the concepts considered for the purpose of expanding the flight envelope of rotorcraft. The study of the compound gyroplane showed its advance capabilities for this purpose. Understanding its characteristics, a number of calculations are conducted to implement a sizing program for compound gyroplanes based on the conventional helicopter sizing process.

The results of the sizing program were validated using existing aircraft data such as the Challis Heliplane, Carter Copter, FB‐1 Gyrodyne, and Jet Gyrodyne. The program is appropriate to size a compound gyroplane at the conceptual design phase. An optimisation study was also performed to enhance sizing results. The compromise between the rotor lift sharing factor and the ratio of the wing span (Bw) to rotor diameter (D) was solved by choosing the total gross weight (TOGW) as the objective function, while the design variables are compromising factors. The optimum results showed that the TOGW of all four kinds of compound gyroplanes was considerably reduced.

A conceptual sizing program for unconventional compound aircraft was developed. The study showed that an optimum design process is necessary to enhance the sizing results.

The purpose of this study was to examine the indirect effects of strategic leadership for learning between sales employees’ perceived learning opportunities and organizational commitment and job performance.

A total of 204 responses from sales employees in a South Korean company were analyzed using path analysis to test the hypothesized model and hypotheses.

Results of the analysis showed that strategic leadership has a significant indirect effect on the relationship between perceived learning opportunities and job performance and organizational commitment.

The results of this study challenge the belief that providing learning opportunities improves salesperson performance and organizational commitment. The results indicate that the relationship between continuous learning opportunities and performance, as well as between opportunities and organizational commitment, is statistically nonsignificant. However, the authors did find that providing continuous learning opportunities via strategic leadership because learning increases performance and organizational commitment.

Recently the route connecting the trans-Korean railway and the trans-Siberian railway has become of particular interest for many academics and policy-makers in East Asian countries. The extensive review of previous studies, however, reveals that literature on the subject is lacking solid analytical framework. Most studies are one-sided, focusing on the political aspects of the issue or paying little attention to the economic aspects of the problem.

This study intends to develop an analytical framework through which the most efficient route among four major alternative routes connecting the trans-Korean and trans-Siberian railways can be identified. It attempts to assign priorities to the four alternative routes according to their level of economic efficiency.

This study utilizes a simple cost-benefit analysis in evaluating the four routes. Cost side, transportation time, effectiveness of customs procedures, and gauge difference are selected as the main economic factors. The volume of cargo, industrial production in adjacent regions, access to natural resources, and market size and foreign investment climate are used to evaluate the benefits of the routes.

The study concludes that Route 3, which connects ‘Busan - Seoul (South Korea) –Pyongyang -Sinuiju (North Korea) –Shenyang –Beijing - Erenhot (China) –Ulaanbaatar (Mongolia) –Ulan-Ude - Moscow (Russia)’ is the most efficient route.
