This paper examines whether the successful bid rate of the OnBid public auction, published by Korea Asset Management Corporation, can identify and forecast the Korea business-cycle expansion and contraction regimes characterized by the OECD reference turning points. We use logistic regression and support vector machine in performing the OECD regime classification and predicting three-month-ahead regime. We find that the OnBid auction rate conveys important information for detecting the coincident and future regimes because this information might be closely related to deleveraging regarding default on debt obligations. This finding suggests that corporate managers and investors could use the auction information to gauge the regime position in their decision-making. This research has an academic significance that reveals the relationship between the auction market and the business-cycle regimes.

While the origin of Korean Industrial Relations goes back 150 years when the country opened its seaports to foreign countries, it didn’t emerge as a field of study until 1950s when academics began to write books and papers on the Korean labor movement, labor laws, and labor economics. In this paper, we sketch this history and describe important events and people that contributed to the development of industrial relations in Korea. Korean industrial relations in the early 20th century were significantly distorted by the 35-year-Japanese colonial rule (1910–1945). After regaining its independence, the U.S. backed, growth-oriented, military-based, authoritarian Korean government followed suit and consistently suppressed organized labor until 1987. Finally, the 1987 Great Labor Offensive allowed the labor movement to flourish in a democratized society. Three groups were especially influential in the field of industrial relations in the early 1960s: labor activists, religious leaders, and university faculty. Since then, numerous scholars have published books and papers on Korean industrial relations, whose perspectives, goals, and processes are still being debated and argued. The Korean Industrial Relations Association (KIRA) was formed on March 25, 1990 and many other academic and practitioner associations have also come into being since then. The future of industrial relations as a field of study in Korea does not seem bright, however. Issues regarding organized labor are losing attention because of a steadily shrinking unionization rate, changing societal attitude toward labor unions, and the enactment of new and improved laws and regulations regarding employment relationships more broadly. Thus, we suggest that emerging issues such as contingent workers, works councils and tripartite partnership, conflict management, and human rights will be addressed by the field of industrial relations in Korea only if this field breaks with its traditional focus on union and union–management relations.

The purpose of this paper is to analyse international political economy (IPE) thought in Korea during its pre-modern and colonial eras.

It divides these eras into three periods. The first period is the eighteenth century, in which Silhak arose. The second is the mid- and late nineteenth century, a time characterised by conflicts between Wijeong-cheoksa and Gaehwa thoughts. The final period is that of colonial Korea under imperial Japan, and during this time economic nationalist movements were pursued while Marxist theories were also introduced to the country.

This research shows that IPE thoughts analogous to Western economic liberalism and economic nationalism did emerge endogenously in Korea when its environment was similar to those in which these Western thoughts arose, although in ways that reflected Korea’s peculiar situations of the times. This study also demonstrates that the “economic” thoughts of the Koreans in these periods were shaped largely by their political thoughts.

This research contributes to the building of a more “globalised” intellectual history of classical IPE thought.

Evolutionary operation (EVOP) is a continuous improvement system which explores a region of process operating conditions by deliberately creating some systematic changes to the process vairable levels without jeopardizing the product. It is aimed at securing a satisfactory operating condition in full‐scale manufacturing processes, which is generally different from that obtained in laboratory or pilot experiments. Information on how to improve the process is generated from a simple experiemental design. Traditional EVOP procedures are established on the assumption that the variance of the response variable should be small and stable in the region of the process operation. However, it is often the case taht process noises have an influence on the stability of the process. This process instability is due to many factors such as raw materials, ambient temperature, and equipment wear. Therefore, process variables should be optimized continously not only to meet the target value but also to keep the variance of the response variables as low as possible. We propose a scheme to achieve robust process improvement. As a process performance measure, we adopted the mean square error (MSE) of the replicate response values on a specific operating condition, and used the Kruskal‐Wallis test to identify significant differences between the process operating conditions.

The purpose of this paper is to identify security technologies that are essential in making home network systems secure and to describe specialized security mechanisms for the home network and the relationships among them.

The research model is designed to support three functions: authentication, authorization, and security policy. Authentication is tested in several methodologies such as id/pw, certificate, or bio; authorization is tested using RBAC methodologies; and security policy is specified using newly‐designed script language, such as xHDL.

The findings for “authentication” suggest that home network users can access services conveniently and securely. In addition, the findings for “security policy” suggest that security policy for home network requires specialized rather than general specification.

The paper identifies three security functions essential for home network: authentication that supports most existing authentication mechanisms, so as to maximize user accessibility; authorization that is middleware‐independent and beyond the physical transport layer; and security policy optimized for the home network environment.

The paper focuses on an implementation‐based security model for the home network. Though interest and research in home network security are increasing, only limited authentication applications have been adopted in real deployment up to now. This paper introduces an integrated security model and emphasizes safety and convenience so as to promote reliability in home network services.

With increasing attention to sustainability in port operations, the purpose of this paper is to analyze the role of sustainability practice (SP) as a moderator on the relationships between competitiveness and performance in port operations.

To explore the specific route of SPs in managing competitiveness and performance, this study adopted the hierarchical moderated regression analysis. Additionally, to analyze the difference in the level of implementation of SP, alternative subgroup analysis was conducted via independent sample t-tests in SPSS 21.

Research results have shown the role of SPs in achieving outstanding port activities, which significantly moderates the relationship between competitiveness, particularly for operational efficiency and service quality, and performance.

As this study is based on cross-sectional data, it does not tap any temporal attitude change, which would require a longitudinal approach. The authors contribute to filling a void between what is achievable and how sustainable practice contributes to managing competitiveness and performance, based on commercial port operations.

Results provide useful insights to establish the strategies to develop sustainable port operations and a strategic agenda to assist ports to incorporate SP.

Drawing on multiple theories, this study advances the role of SP by shedding new light on how it improves operational sustainability through strengthening the relationships between competitiveness and performance.

This paper investigates a retrospective on the Journal of Derivatives and Quantitative Studies (JDQS) on its 30th anniversary based on bibliometric. JDQSs yearly publications, citations, impact factors, and centrality indices grew up in early 2010s, and diminished in 2020. Keyword network analysis reveals the JDQS's main keywords including behavioral finance, implied volatility, information asymmetry, price discovery, KOSPI200 futures, volatility, and KOSPI200 options. Citations of JDQS articles are mainly driven by article age, demeaned age squared, conference, nonacademic authors and language. In comparison between number of views and downloads for JDQS articles, we find that recent changes in publisher and editorial and publishing policies have increased visibility of JDQS.
