The purpose of this paper is to investigate the predictors of game addiction based on loneliness, motivation and inter-personal competence using the samples of college students recruited from South Korea (n=251).

The authors examined the underlying mechanism of game addiction by testing a moderated mediation model, in which inter-personal competence moderated the mediation model of loneliness, regulatory focus and online game addiction. First, the authors clarified the relationship among loneliness, motivation and inter-personal competence, to understand the influences of loneliness on other variables in this study (mediation test). Second, the authors examined the underlying mechanism of game addiction by testing a moderated mediation model, in which inter-personal competence moderated the mediation model of loneliness, regulatory focus and online game addiction (moderated mediation).

Regulatory focus mediated the effect of loneliness on online game addiction. Moderated mediation analyses using PROCESS confirmed that inter-personal competence significantly buffered the indirect effect of loneliness (through regulatory focus) on online game addiction. The findings indicated that inter-personal competence accounted for significant differences in the mediation models.

This study bridges the gap in the online game addiction literature by explaining how loneliness is associated with online game addiction.

The purpose of this paper is to investigate the market structure and the key drivers of the competitiveness of an agile and collaborative fast fashion supply chain using South Korea’s Dongdaemun fashion market – one of the world’s largest and most competitive fashion hubs – as an example.

A qualitative approach is employed with a two-stage study. The first stage is a preliminary study based on a desk research and several field visits, while the second is an in-depth interview study with seven informants collectively representative of the members of all echelons along a fashion supply chain.

The findings demonstrate that the Dongdaemun fashion market has a complex market structure and a unique business pattern. Supply chain agility and collaboration are two important components of its success, which are supported by five factors: self-sufficient structure, multiple-integrated network, strong entrepreneurship, close and long-lasting buyer-seller relationships, and quick-response product delivery and inventory replenishment.

This study extends our knowledge of supply chain management in the fast fashion industry and provides insights to assist in the development of supply chain strategies in other fashion markets and/or other industries. The extended conceptual framework as well as the proposed questions may serve as points of reference for future studies in the subject area.

The revitalization of big data has gained attention in the public sector. However, such open government data (OGD) is facing major challenges with respect to data quality and limited use. To solve this problem, this study analyzes the factors driving the use of OGD from the perspective of data providers in the public sector.

Using the analytic hierarchy process and analytic network process methodologies, the importance of the factors driving the use of big data in the public sector was ranked. In addition, the different characteristics of tasks among the departments in a public agency were compared based on expert interviews.

The factors driving OGD use are not only political environment or the technological environment. The importance of the institutional culture within the organization increases with the motivation of the data provider. The priorities of the OGD factors also depend on the objectives of the department involved.

This study provides implications for improving the publication of open data by analyzing the priorities of the factors driving its use from the perspective of big data providers. It focuses on different perceptions of the factors valued by public officials in charge of data in institutions. The results suggest the need to explore officials' perceptions of value creation in big data fields.

The purpose of this paper is to compare customer experience (CE) between digital and traditional South Korean bank users and its relationship with customer satisfaction (CS).

A survey of bank customers was conducted, and an ANOVA test was performed to compare the means of CS between digital and traditional bank (TB) users as well as four dimensions of CE, such as usefulness, convenience, employee-customer engagement (ECE) and security. The ordinal regression analysis was also performed to test the moderation effect of digital bank (DB) use on the relationship between CE and satisfaction.

The means of usefulness were higher among DB users than TB users. By contrast, ECE and security means were lower for digital than TB users. The ordinal regression analysis indicated that DB use had a moderating effect on the relationship between convenience and CS and the relationship between ECE and CS. DB use encouraged increased positive relationships between convenience and CS, and moderated the relationship between ECE and CS in a negative direction.

ECE and security for DBs is weak. Therefore, bank executives need to improve these areas through real-time customer services and adding authentication procedures.

Unlike previous studies, this study proposed a model that reveals differences in CE between traditional and DB users. It explored the effects of CE on CS to contribute to the continued development of South Korean DBs.

In this paper, a three-dimensional (3D) printer-based manufacturing line and supporting system, which supports personalized/customized manufacturing for individual businesses or start-up companies, was studied to evaluate the practicality of using additive manufacturing for personalization/mass customization.

First, factory-as-a-service (FaaS) system, which provides factory as a service to customers, was proposed and designed to manufacture various products within a distributed manufacturing environment. This system includes 3D printer-based material extrusion processes, vapor machine/computer numerical control machines as post-processes and assembly and inspection processes with an automated material handling robot in the factory. Second, a virtualization module for the FaaS factory was developed using a simulation model interfaced with a cloud-based order and production-planning system and an internet-of-things-based control and monitoring system. This is part of the system for manufacturing operations, which is capable of dynamic scheduling in a distributed manufacturing environment. In addition, simulation-based virtual production was conducted to verify and evaluate the FaaS factory for the target production scenario. Main information of the simulation also has been identified and included in the virtualization module. Finally, the established system was applied in a sample production scenario to evaluate its practicality and efficiency.

Additive manufacturing is a reliable, feasible and applicable technology, and it can be a core element in smart manufacturing and the realization of personalization/mass customization.

Various studies on additive manufacturing have been conducted with regard to replacing the existing manufacturing methods or integrating with them, but these studies mostly focused on materials or types of additive manufacturing, with few advanced or applied studies on the establishment of a new manufacturing environment for personalization/mass customization.

The purpose of this study is to examine the association between additional audit efforts and clients’ future equity value. The study hypothesizes that auditors’ additional audit efforts directly increase clients’ stock return performance. Additionally, this study expects that the additional audit effort lowers the likelihood of audit failure and improves accounting information quality, thereby indirectly increasing clients’ future equity return performance.

The regression and portfolio return tests are conducted using observations from 2003 to 2016. This study uses the abnormal audit hours as a proxy for additional audit effort using mandatorily disclosed audit hour data from Korean listed firms. The study also conducts mediation analyses to examine the causal intermediate steps that link audit effort to client equity return performance.

The paper documents a significant and positive association between abnormal audit hours and clients’ subsequent years’ stock return performance and Tobin’s Q. This finding is accentuated for clients audited by Big N auditors or with greater demand for superior audit service. This finding is robust after controlling for various proxies of accounting quality. The portfolio return tests also find evidence that investors cannot fully perceive the value of audit efforts. A battery of additional tests does not alter the main findings.

The results provide implications for investors and policymakers by emphasizing the importance of audit efforts in value-creation. Moreover, this study’s findings suggest that auditors’ assurance, insurance and information roles are all the important drivers of this value-creation.

This study highlights a prominent feature of audit effort that enhances the value of auditees.

The purpose of this study is to investigate critical factors needed for an internal environment conducive to entrepreneurial activity. Also, this study aims to suggest improved measurement items that can be applied to national corporations in the national management environment where is much interested in the implementation of corporate entrepreneurship.

In particular, by using the corporate entrepreneurship assessment instrument (CEAI) and through the Delphi and analytical hierarchy process (AHP) surveys on the group of corporate entrepreneurship experts, a comparative analysis among the emergent four kinds of types is deducted with main internal environmental factors of corporate entrepreneurship activities in South Korea.

This study contributes to the decision-making of many organizations about new business directions and success factors to gain new growth opportunities with corporate entrepreneurship activities according to each of their own internal environment status. As a result of the AHP analysis on the opportunist type, work discretion was revealed as the most significant factor. Furthermore, the avoiding identical work approach/steps, the subjective work assessment and the opportunities to practice one’s own style were all recognized as crucial enough to occupy the top to fourth place in the overall importance priority.

Academically, the local organizational environmental critical factors based on an existing CEAI were issued by allowing the AHP survey with specific scenarios per corporate entrepreneurship activity. This can be applied through various means to benefit many organizations looking for continuous growth and innovation based on corporate entrepreneurship.

The purpose of this paper is to investigate the mediating effects of organization-based self-esteem (OBSE) for the relationship between workplace ostracism with helping behavior, voicing behavior, in-role behavior, and deviant behavior. The workplace has now become a social context where ostracism occurs and the study emphasizes how ostracism can affect workplace behaviors.

The study was designed using a three-wave self-reported survey. Confirmatory factor analysis, structural equation modeling, and bootstrapping for indirect effects were conducted to test the study’s hypotheses.

The study found OBSE to fully mediate the relationship between workplace ostracism and helping behavior, voicing behavior, and in-role behavior, while OBSE partially mediated workplace ostracism and deviant behavior as workplace ostracism was found to have a direct effect on deviant behavior.

The study explores and empirically tests the mediating effects of OBSE with helping behavior, voicing behavior, in-role behavior, and deviant behavior. Therefore, the study extends research on workplace ostracism by investigating beyond the direct effects of workplace ostracism on workplace behaviors.

Many see the United States as a country of immigrants, but an examination of the past 150 years of education and language policies regarding immigrant children shows a tendency toward the disservice and underservice of many immigrant children. In this study, the authors conduct a historical analysis of how immigration, education, and language-related legal issues have affected the schooling of Asian Americans. The authors hope that this case study will improve educational policies and practices making them equitable educational opportunities for all immigrant children

The purpose of this paper is to develop a novel research model to examine the relationship among information sharing (IS), supply chain integration (SCI), operational performance (OP) and business performance (BP) in the fashion supply chains.

A survey of 247 executives from Chinese fashion brand firms was conducted and the data were analyzed to investigate how IS affects the organizational BP. Structural equation modeling (SEM) was applied to study the relationship among IS, SCI, OP and BP.

The empirical research results indicate that IS is critical to enhance the SCI and OP, and both SCI and OP exert mediating effects on BP of fashion brands. This result also reveals constructive suggestions that allow fashion brands to strengthen their SCI and OP, as well as BP.

Multiple data sources were applied to develop the sampling frame, and respondents were selected (according to their experience and position) to ensure they had the knowledge and expertise to provide valid response. However, this could not guarantee the adequacy of the sample. This limitation is compounded by the reliance on a simple respondent per firm, which precludes testing for inter-rater reliability.

The empirical findings provide an enhanced understanding of the relationship among IS, SCI, OP and BP in Chinese fashion brand settings. The research results will help fashion brands to improve supply chain efficiency and enhance company performance.

Although previous studies have realized that the value of IS varies in different industries, few have specifically explored the impact on the fashion industry characterized by short life cycles, high volatility, low predictability and high impulse purchasing. To fill this knowledge gap, the present study employed a questionnaire survey and SEM techniques to explore the relationship among IS, SCI, OP and BP in the fashion supply chain. Comprehending the impact mechanism of IS on organizational performance can provide useful management insights into the development of effective strategies that allow enterprise to improve BP.
