The purpose of this paper is to investigate the effect of empowering leadership on employees’ psychological well-being (PWB) and job engagement. This study also examines the mediating role of psychological capital (PsyCap) in these relationships.

The study draws on survey data (n=285) from employees in eight large-sized firms in South Korea. Confirmatory factor analysis was conducted to examine the convergent validity of the construct measures. Structural equation modeling was used to estimate the fit of the hypothesized model to the data.

The authors found that empowering leadership influenced job engagement both directly and indirectly through PsyCap. Employees’ PsyCap fully mediated the relationship between empowering leadership and employees’ PWB, while partially mediating the relationship between empowering leadership and job engagement.

This is the first empirical study to examine the effects of empowering leadership behaviors of leaders on both PWB and PsyCap, which are positive psychological resources of employees. The study has also provided empirical evidence for the importance of PsyCap, which plays a positive role in the ability of employees to manage their overall feelings in achievement situations and in employees’ engagement in the workplace.

The purpose of this study is to investigate the effects of leaders' managerial coaching on followers' organizational citizenship behavior (OCB), creativity and task performance. This study also examined the mediating role of intrinsic motivation and self-efficacy, recognizing the follower’s attitude and cognition as essential elements of behavioral changes.

This study collected data from 20 companies across multiple industries in South Korea, and a total of 386 leader–follower dyads' data were used.

The results show that leaders' coaching is positively associated with OCB directly, but a direct impact of coaching on creativity and task performance was not supported. The results also showed that intrinsic motivation partially mediates the effect of coaching on OCB and fully mediates the effect of coaching on creativity and task performance. Self-efficacy played a role as a full mediator between coaching and task performance.

This study considered both the cognitive and affective aspects of managerial coaching and examined the influence of managerial coaching on the followers' in-role and extra-role behaviors (i.e. OCB, creativity and task performance) using responses from both the leaders and the followers at multiple organizations. Specifically, the results of this study empirically illustrated that managerial coaching by leaders serves as a mechanism mediated through intrinsic motivation and self-efficacy, linking to employees' OCB, creativity and task performance. This provides a clear explanation of the processes through which managerial coaching impacts employees and offers insights into the specific aspects that organizational leaders should focus on when engaging in managerial coaching.

The purpose of this study is to examine employees' perceived influence of the learning organization culture and learning goal orientation on their knowledge sharing attitude and intention across multiple industries. In connecting these concepts, the researchers incorporated theories of the knowledge-based firm, goal orientation and reasoned action.

A survey was used to collect data from a total of 323 responses from eight South Korean organizations to examine the influence of organizational and individual learning factors on employees' knowledge sharing. Structural equation modeling showed that the proposed research model was supported by item internal consistency and model-fits.

Results indicated that employees' learning goal orientation, knowledge sharing attitude and learning organization culture positively influence employees' knowledge sharing intention. This study highlights that those employees are more likely to share knowledge when employees with high learning goal orientation form a positive attitude toward knowledge sharing in a learning supportive culture and structure.

This study added to the literature of learning organizations by identifying a strong positive connection between the learning organization culture and employees' knowledge sharing. The theoretical contribution of this study lies in which the important roles were extended that the learning goal orientation exerts on employee behaviors when they perceive the organization valuing learning.

An anomaly of entrepreneurship literature was that, despite serious efforts required to manage a business, few studies had investigated entrepreneurs' health conditions at the end of their careers. This study investigated whether one's entrepreneurship in a lifetime enhanced their health after a career plateau.

The authors tested the main effect and mediating effects of entrepreneurs' life habits and self-esteem, respectively, using two longitudinal representative examples with 8,984 and 12,686 participants.

Results indicated that entrepreneurship significantly improved individuals' general lifetime health condition. Moreover, life habits (e.g. vigorous activities or sports, light activities, drinking habits and diet habits) and self-esteem significantly mediated the relationship between entrepreneurship and lifetime health. Entrepreneurs tended to have better health due to healthier life habits and higher self-esteem than salaried employees. In this paper, the authors also discussed theoretical and practical implications.

The authors proposed and found that, to counter the harsh requirements of entrepreneurial actions, entrepreneurs need to seek personal physical and psychological resources, and these resources can benefit their health even after decades.

The purpose of this paper is to examine the mediating role of burnout (i.e. exhaustion, cynicism, professional inefficacy) in the relationship between job level and job satisfaction as well as between job level and task performance.

The final sample included 342 Korean workers from selected companies. The authors employed the Hayes (2013) PROCESS tool for analyzing the data.

The results showed that all three subscales of burnout (i.e. exhaustion, cynicism, professional inefficacy) mediate the relationship between job level and job satisfaction. However, only two mediators (i.e. cynicism, professional inefficacy) indicated the mediating effects on the association between job level and task performance.

This research presented the role of burnout on the relationships between job level, job satisfaction, and task performance especially in South Korean organizational context. In addition to role of burnout, findings should prove helpful in improving job satisfaction and task performance. The authors provide implications and limitations of the findings.

Employee well-being has been an under-researched area in the field of human resources (HR) and organizational behavior. The purpose of this paper is to investigate personal (learning goal orientation (LGO)), contextual (empowering leadership), and job-related (psychological empowerment) antecedents of psychological well-being (PWB).

Individual perceptions of knowledge workers in nine Korean consulting firms in South Korea were obtained using a cross-sectional survey. HR managers distributed paper versions of a survey questionnaire to 400 employees, and 334 usable questionnaires were collected, giving the authors a final response rate of 83.5 percent.

As a result of structural equation modeling analysis, the level of employees’ psychological empowerment turned out to partially mediate the relationship between LGO and PWB, while fully mediating the relationship between empowering leadership and PWB. LGO and perceived empowering leadership accounted for 54 percent of the variance in psychological empowerment and the three antecedents explained 47 percent of the variance in PWB.

This study relied on a cross-sectional survey method with potential common method bias. As a result of the single-factor test, however, it is unlikely to confound the interpretations of the results. Another limitation of this study is that the sample of this study was restricted to knowledge workers with relatively high cognitive ability since they were mostly junior male managers with four-year college or graduate degrees.

To enhance perceived empowerment and PWB, HR, and OD practitioners can support employees and their managers by providing relevant HR practices and services including developing supportive empowering leaders with effective coaching skills, hiring, and developing employees with higher LGO, and redesigning jobs for employees so they feel more empowered.

This study linked four emerging subjects in management and positive psychology: goal orientation, empowering leadership, psychological empowerment, and well-being research. The theoretical contribution of this study lies in that it is one of the first attempts to investigate the relationships among LGO, psychological empowerment, and PWB specifically for knowledge workers in South Korea.

While guanxi is by far the most prominent network construct in international business research, the literature on other informal network constructs (wasta, sifarish, svyazi, yongo, etc.) is emerging. Though guanxi research suggests that the influence of informal networks in business may recede with increasing levels of economic growth and institutional effectiveness, this hypothesis remains to be tested in different contexts using varied network constructs in order to come to general conclusions. Assuming that informal networks are culturally rather than institutionally driven, we elaborate on the developmental dynamics of informal networks in Korea, namely yongo and inmaek, arguing that yongo persists and adjusts to changes in the sociocultural environment. While we define traditional yongo based on three in-group ties (family, university, and regional ties), today we see workplace-related ties and networks becoming an increasingly important yongo base, which we call yongo 2.0. Societal trends reflected in the so-called spoon-class theory and N-po generation debate mirror the ambivalence of traditional yongo and the reliance on yongo 2.0. Hence, we assume that yongo will not recede but remain an important in-group tie that foreign business expatriates need to understand and learn to access in order to manage business effectively and integrate into society.

The weapon system of The Navy is the small quantity producing system on multiple kinds. It is consisted of various equipment and the subordinate parts of those which can repair the damaged part. The operating procedure concerning warship's repair parts managed under these systems is as follows. Firstly, if demand of repair parts occurs from warship which is the operating unit of weapon, then the Fleet(the repair & supply support battalion) is in charge of dealing with these requests. If certain request from warship is beyond the battalion's capability, it is delivered directly to the Logistic Command. In short, the repair and supply support system of repair parts can be described as the multi-level support system. The various theoretical researches on inventory management of Navy's repair parts and simulation study that reflects reality in detail have been carried out simultaneously. However, the majority of existing research has been conducted on aircraft and tank's repairable items, in that, the studies is woefully deficient in the area concerning Navy's inventory management. For that reason, this paper firstly constructs the model of consumable items that is frequently damaged reflecting characteristics of navy's repair parts inventory management using ARENA simulation. After that, this paper is trying to propose methodology to analyze optimal inventory level of each supply unit through OptQuest, the optimization program of ARENA simulation.
