Abstract
Purpose
This study proposes practical digitalization strategies and well-grounded evaluation criteria for maritime container supply chains.
Design/methodology/approach
The authors identified the status of supply chain digitalization of the Port of Busan in South Korea and developed three digitalization strategies based on industry requirements and consultations with port experts. The authors proposed 11 evaluation criteria for examining the main digitalization strategies in the supply chain operations reference model, based on a survey among 46 experts and used multi-criteria decision-making approaches to prioritize the strategies and evaluation criteria.
Findings
The results delineate the status of the digitalization of a real-world port-focal supply chain. The model can be successfully customized to include well-grounded evaluation criteria for digitalization strategies, and presents a practical way to advance the supply chain digitalization strategies. Based on the survey and evaluation, the authors find that increasing data accessibility and improving quality are preferred to adopting a data and information sharing platform.
Research limitations/implications
As the study is limited to the Port of Busan, future case studies could be undertaken to container supply chains driven by different regional ports.
Practical implications
Stakeholders, such as truckers, terminal operators, and shipping liners, might consider the proposed strategies and evaluation criteria when digitalizing their supply chains.
Originality/value
By identifying the needs and specifications of maritime container supply chain digitalization strategies, developing evaluation criteria, and conducting a case study for proof of concept, the study proposes an operational management process with practical, real-world benefits for port-focal supply chains.

Abstract
This chapter focuses on South Korea’s newly found regional leadership, as the emergent middle power of East Asia, in order to advance regional integration and institution-building. Policy leadership is observed and analyzed from an international lens, linked to the literature of middle powers. The chapter first conceptualizes middle powers in connection with the issue of international leadership, since such states often play important roles in promoting cooperation. The chapter looks especially into South Korea’s foreign policy behavior toward East Asian regional processes and how it has manifested innovative and capable leadership. More specifically, the last three presidencies of Kim Dae-jung (1998–2002), Roh Moo-hyun (2003–2008), and Lee Myung-bak (2008–2013) are scrutinized in the hope of underscoring how their particular administrations, political leadership, and strategic approaches to foreign policy toward the region influenced South Korea’s regional leadership attempts and middle power status.

Abstract
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.

Abstract
Purpose
This paper aims to identify the relationship between participation motivation, satisfaction and exercise adherence intention of golf range users on the basis of self-determination theory.
Design/methodology/approach
For this purpose, the authors proposed research questions and a conceptual research model as well. Then, the authors surveyed users of golf ranges located in Seoul Metropolitan City and Gyeonggi-do province.
Findings
By applying convenience sampling, the authors received a total of 313 questionnaires. Results were as follows. First, among the participation motivation sub-factors, health-oriented motivation, achievement motivation, pleasure-oriented motivation and self-displayed motivation had a significant effect on emotional satisfaction, while achievement motivation and pleasure-orientation motivation had a significant effect on performance satisfaction. Second, the following participation motivation factors had a significant effect on exercise adherence intention: health-orientation motivation, achievement motivation and pleasure-orientation motivation. Third, among the satisfaction factors, emotional satisfaction and performance satisfaction both had a significant effect on exercise adherence intention.
Originality/value
This is one of the first papers to examine the relationships that exist between golf range users’ participation motivation, satisfaction and exercise adherence intention.

Abstract
Purpose
Although there are a number of studies on the factors affecting the continuance usage intention for social network services (SNS), the studies on the integrated model encompassing SNS qualities (information, system, and service quality, and hedonic value, which are gratifications for SNS usage), flow, relationship quality (which are trust and satisfaction), and continuance intention are almost non-existent. Based on Bagozzi’s self-regulation framework, the IS success model, uses and gratification theory, and flow theory, the purpose of this paper is to examine the qualities and hedonic value of SNS, which have an influence on flow experience and relationship quality which are posited to affect the continuance usage intention.
Design/methodology/approach
This study used an e-mail survey method to collect 460 questionnaires for the final sample. The sample of the study includes college students or job workers who have experience in using SNS. Various user categories in terms of gender, school degree, occupation, usage years, and daily time of usage were included.
Findings
The study results show that system, service quality, and hedonic value have an impact on flow experience, information and service quality, and hedonic value influence the relationship quality of SNS. The flow experience and relationship quality while using SNS affect the continuance usage intention of SNS. This results show that the consideration of various SNS qualities, hedonic value, flow experience, and relationship quality is necessary to actively explore the factors for continuance usage intention for SNS.
Practical implications
IS managers trying to understand reuse intent can use surveys on information, system, and service quality, and hedonic value. Practitioners should constantly incorporate and develop various activities or useful applications to allow people to reach out to each other, to reinforce users’ attention, interaction, and increase social connections, trust, satisfaction, and further intensify users’ intention to use, increasing SNS value. The findings explain a mechanism through which SNS users’ continuance intention is built. Understanding this mechanism provides valuable information for practitioners to understand the qualities driving SNS users’ intention to revisit SNS.
Originality/value
This study sheds light on the existing literature on website usage that focuses on the design qualities as this paper has combined website quality perspective, i.e., information, system, and service quality, and hedonic value, and the flow and relationship perspective to investigate how these constructs would affect users’ intention to continuously use SNS. On the basis of four theories, Bagozzi’s self-regulation framework, IS success model, users and gratification theory, and flow theory, this study extended the previous studies on SNS by adding information, system, and service quality, hedonic value, flow and relationship quality as second-order constructs affecting continuance intention.

Abstract
Purpose
Drawing on survey data from South Korean police officers, the purpose of this paper is to explore the mediation effects of coping self-efficacy and social support in the relationship between the impact of traumatic events and resilience. Additionally, the moderation effects were assessed to examine how this relationship varies by the state of police officers’ mental health.
Design/methodology/approach
Both multiple mediation and multiple group models within the structural equation modeling framework were adopted to assess the proposed mediating and moderating effects.
Findings
Traumatic events affect resilience not just directly but also indirectly through mediating factors such as coping self-efficacy and social support. These patterns are more pronounced in the high-risk mental health group than in the normal group.
Practical implications
If exposure to traumatic events were an unavoidable aspect of police work, helping officers build resilience as a general capacity to overcome stressful situations would be an effective strategy to prevent many negative consequences associated with the traumatic events. This study examined specific causal mechanisms linking the impact of traumatic events to resilience to better understand the process of developing resilience among police officers.
Originality/value
Instead of further examining the relationship between impact of traumatic events and other physical and mental outcomes, this study attempted to expand the current literature by identifying important mediating and moderating mechanisms that reduce the negative influences of traumatic events on resilience.

Abstract
Purpose
Catastrophic supply chain disruptions can significantly damage the operational and financial performance of firms. While a growing body of literature on supply network structures has studied what influences supply networks' vulnerability to supply chain disruptions and capability to recover from them, it remains unclear how supply network structures change after major supply chain disruptions. We aim to provide an understanding of how these changes occur.
Design/methodology/approach
Using a natural experiment approach and supply network data from Factset, this study investigates how firms' supply network structures change after experiencing the catastrophic supply chain disruptions caused by the 2011 Tohoku earthquake and tsunami in Japan. We capture post-earthquake supply network changes using the measures of degree centrality and ego network density.
Findings
The results of the analysis suggest that compared to unaffected firms, the affected firms experience changes in their supply network structures tending toward lower complexity measured by in-degree centrality, out-degree centrality and ego network density.
Originality/value
This study contributes to social network theory and the complex adaptive supply network literature by providing empirical evidence of structural changes in supply networks after catastrophic supply chain disruptions. A managerial contribution is made by providing a reflection on why these changes might be occurring and alert firms to the challenges of managing complexity in their supply networks.

Abstract
Purpose
The purpose of this paper is to make clear how managers in Western organizations can understand the Japanese and Korean cultural value system and interpret the strategic decision‐making process that exists within organizations exhibiting a collectivist culture.
Design/methodology/approach
A literature review was undertaken and several studies, either jointly or separately undertaken by the authors, were drawn upon in order to provide depth to the analysis and interpretation.
Findings
Although there are similarities between Japanese and Korean people, there are a number of distinct differences between them. These differences have come about as a result of Buddhism and Confucianism being adopted at different points in each country's history, and the fact that these countries have developed their own unique cultural value system. The differences manifest in organizational characteristics, which provide Japanese and Korean organizations with a specific identity, management model and way of doing business. What is evident, however, is that managers in both Japanese and Korean organizations are familiar with the relationship marketing concept and actively embrace the strategic marketing approach.
Research limitations/implications
Undertaking research into national cultural value systems and organizational cultural value systems is complex and requires an interdisciplinary approach. It can also be suggested that more emphasis needs to be placed on undertaking research of this kind in both Japan and Korea. Furthermore, it is advocated that a longitudinal study is undertaken in order to provide both evidence of how organizational cultural value systems within a collectivist culture change through time, and how cultural traits influence the decision‐making process.
Practical implications
Managers in Western organizations will be able to relate to the value systems of Japanese and Korean organizations and as a consequence, will understand how long‐term trustworthy relationships are developed. This should facilitate the negotiation of business deals and result in business partnerships being developed that are based on mutuality.
Originality/value
The interdisciplinary approach adopted allowed the authors to view culture from several perspectives and to link more firmly national cultural value systems with organizational cultural value systems, and with organizational identity. By adopting this research strategy, the authors were able to explain how organizational identity is influenced by and reinforced by the concept of strategic marketing.

Abstract
Purpose
The purpose of the study was to explore heat-accumulative and thermal-conductive characteristics of copper-graphene composite film (Cu-G film) while applying it to a human-skin analogue.
Design/methodology/approach
In the preliminary experiment, the authors evaluated the thermal conductive characteristics of the Cu-G film in three covered conditions (no film, copper film, and Cu-G film conditions). For the first factorial experiment, the heat-accumulative properties over heated pig skin were compared at air temperatures of 10, 25 and 35°C. For the second factorial experiment, 105 trials were conducted on pig skin by combining air temperatures, trapped air volumes, and numbers of film layers.
Findings
The results from the preliminary experiment showed that the Cu-G film distributed the surface heat to the outside of the Cu-G film, which resulted in even distribution of heat inside and outside the Cu-G film, whereas the copper film accumulated heat inside the copper film. The human-skin analogue of pig skin, however, showed the opposite tendency from that of the plastic. The pig-skin temperatures beneath the Cu-G film were higher than those beneath the copper film, and those differences were remarkable at the air temperature of 10°C. The accumulative heat was affected by the trapped air volume, fit to the skin, and number of Cu-G film layers.
Originality/value
In conclusion, the Cu-G film more effectively accumulated heat on the human-skin analogue than copper film, and those effects were more marked in cold environments than in mild or hot environments.

Abstract
Purpose
The purpose of this study is the use of 3D printing technology to perform maintenance on damaged parts on site. To maintain damaged parts, the user needs experience in the parts design and 3D printing technology. To help users who have little or no experience on 3D printing, a part library-based information retrieval and inspection framework was proposed to support the process of manufacturing replaceable parts using a 3D printer.
Design/methodology/approach
To establish the framework, 3D printing-based maintenance procedure was first defined, comprising retrieval, manufacturing and inspection steps, while identifying the technical components required to perform the procedure. Once the technical components are identified, part library-based information retrieval and inspection framework was defined based on the technical components and the relationships between the components. For validation of the concept of the framework, prototype system is developed according to the proposed framework.
Findings
The feasibility of the proposed framework is proved through maintenance experiments on gaskets and O-rings.
Originality/value
The main contribution of this study is the proposal of the framework, which aims to support the maintenance of damaged parts for the user who has little or no experience in part design or does not know how to operate a 3D printer.
