Civil and commercial disputes can be resolved through alternative dispute settlement systems other than court proceedings. Among them, the arbitration procedure is a system that is clearly distinguished from the mediation procedure in which the dispute is terminated by agreement between the parties. The arbitration proceedings shall have the same effect as the result of the final judgment by the decision of a third-party arbitrator, and its essence is a judgment. The Korean Arbitration Association Studies was founded in December 1990 to recognize the importance of arbitration procedures and conduct specialized research on them, with professional research on 'arbitration procedures' continuing until today. Thus, the Korean Arbitration Association Studies is positioned as the only specialized research organization in the field of arbitration. In the case of the Korean Arbitration Association Studies, which is the only society in Korea related to arbitration and alternative dispute resolution, the members are mainly scholars majoring in trade and commerce and ones majoring in law. This situation reflects the distinctive character of the arbitration system because it is a matter of dispute procedures related to trade and commerce and many scholars who research trade and commerce need to prepare for possible disputes. In addition, the arbitration procedure is a dispute settlement procedure that substitutes for litigation because it has research value as a legal system. In particular, the 'Journal of Arbitration Studies' published by the Korean Arbitration Association plays a role in mediation, as well as mediation and presentation of research papers in the ADR field. This study analyzes the trends of mediation and ADR-related papers published in 'Journal of Arbitration Studies', an academic journal of the Korean Arbitration Association Studies, in four dimensions, celebrating the 30th anniversary of the Korean Arbitration Association Studies. First, this study examined which sub-themes are mainly studied among the various viewpoints of mediation through thematic analysis. Second, it looked at what methodology was used to study intervention at the methodological level. Third, it assessed what countries and regions had been mainly studied at the regional level. Fourth, in terms of content, what kind of research had been mainly conducted and what kind of research was relatively insufficient was investigated, analyzing the research results of the last 30 years and presenting a milestone for the research direction of 'Journal of Arbitration Studies' in the future.

This current research investigated whether job stress mediates the relationship between physical environment and safety behavior of members in organization. Furthermore, we hypothesized that safety climate functions as moderator between physical environment-job stress link. In order to examine the hypotheses, 870 employees in various fields of companies were sampled. Using structural equation modeling(SEM), we conducted moderated mediation model analysis which cab elaborately test the significance of our hypotheses. The results showed that job stress mediated the link between physical environment and safety behavior of members. Moreover, the relationship between physical environment and job stress was moderated by safety climate. The implications and limitations of our study and suggestions for future research were discussed.

Background: This study aimed to examine the impact of chronotype on depressive symptoms and explore the mediating effects of sleep quality, pre-sleep cognitive arousal, and social jetlag in a sample of wage earners. Methods: A total of 3,917 waged workers were surveyed online in July 2022. Logistic regression and mediation analysis were used to assess the relationship between chronotype (morningness, intermediate, and eveningness) and depressive symptoms (Patient Health Questionnaire ≥ 5), and the mediating effects of Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI), and Pre-Sleep Arousal Scale (PSAS). All analyses were adjusted for age, education level, income level, marital status, coffee consumption, alcohol consumption, physical activity, occupation, employment status, and working hours to calculate odds ratios (ORs). Results: The chronotypes of all the participants were divided into morningness (4.7%), intermediate (93.5%), and eveningness (1.8%). Multiple logistic regression analysis showed an increased risk of depression in the eveningness chronotype (OR: 2.96; 95% confidence interval [CI]: 1.51, 5.86). Regarding the mediation analysis, ISI mediated 28.44% (95% CI: 16.39-40.5), PSQI for 31.25% (95% CI: 19.36, 43.15), and PSAS-Cognitive Score (PSAS-C) for 23.58% (95% CI: 10.66, 36.50) of the association between chronotype and depressive symptoms. However, social jetlag did not significantly mediate this relationship. (percentage mediated = 0.75%, 95% CI: -3.88, 5.39) Conclusions: Evening chronotypes exhibit an increased risk of depressive symptoms, which ISI, PSQI, and PSAS-C partially mediated. This suggests that interventions to improve sleep quality and maintain adequate sleep habits may effectively prevent and treat depression in employees with an eveningness chronotype.

Elderly males in retirement experiencing a change in their social status and role in the family are likely to develop negative perception toward the elderly and the elderly life. The purpose of this study is to examine how the experiences of age discrimination affect elderly male's perception and his attitude towards the elderly life, and to verify the mediation effects of the family and peer relations, which would necessitate the need for social welfare intervention. 215 participants, the elderly men registered at the welfare centers in Seoul Metropolitan area, participated in this research utilizing the structural equation modeling to verify the mediation effect. The findings are as follows. First, the elderly males's experiences of age discrimination is found not to have a significant effect on their perception towards the elderly. Second, the elderly males' discrimination experience has a significant effect on their attitude towards the elderly life. Third, it is found out that family function and peer relationship has complete mediation effect on the perception on the elderly experiencing discrimination in their perception towards the elderly life. Fourth, the family function and peer relationship has partial mediation effect on the elderly male experiencing discrimination in their attitude toward their life after retirement. This shows that more efforts are needed to reduce discrimination towards the elderly, and that strong family function and peer relations help the elderly to develop more positive perception and attitude towards the elderly life. In conclusion, it proposes an institutional approach towards the problem as well as increased support for elderly welfare service including family counseling intended to strengthen family function and alternative family, and more active social activities aimed at strengthening of peer relationship.

Previous works on safety behavior have paid less attention to the influence of several leadership styles on safety behavior. Among the various leadership styles, I focus on the effect of coaching leadership on safety behavior. To be specific, this paper investigates the impact of coaching leadership on safety behavior and its underlying mechanisms (mediator) as well as contextual factor (moderator). This research examines the sequential mediating effect of perceived organizational support and organizational identification in the association between coaching leadership and safety behavior. Also, work overload will negatively moderate the coaching leadership-perceived organizational support link. My results showed coaching leadership increases employee safety behavior through the sequential mediation of perceived organizational support and organizational identification. In addition, work overload functions as a negative moderator which diminishes the positive effect of coaching leadership on perceived organizational support.

Purpose - The present study examines the effect of service employees' experienced customer incivility through their emotional exhaustion. We identified service employees' emotion regulation ability as a boundary condition (i.e., moderating variable) that decreased the positive relationship between service employees' experienced customer incivility and their emotional exhaustion. Furthermore, we also investigated the negative relationship between service employees' experienced customer incivility and their service performance via emotional exhaustion. Research design, data, and methodology - Drawing on AET (affective event theory) and COR (conservation of resources) theory, we developed three research hypotheses (i.e., mediation, moderation, and moderated mediation). Online panel survey data from 552 frontline employees at several service organizations (e.g., department stores, retail stores, hotels, restaurants, airlines, banking, insurance company, and etc) in South Korea were examined. To assess two types of validity (i.e., convergent and discriminant validity) and reliability of measurement model, we employed the CFA (confirmatory factor analysis) using M-plus 8.2 software. Internal consistency also was tested by Cronbach' α. In addition, we employed the SPSS PROCESS MACRO 2.16, which was recommended by Hayes (2013, 2015), to estimate mediation, moderation, and moderated mediation effects. Results - As predicted, the negative relationship between service employees' experienced customer incivility and their service performance was mediated by emotional exhaustion. Furthermore, service employees' emotion regulation ability also played a significant moderating role of the relationship between service employees' experienced customer incivility and emotional exhaustion, such that this relationship was less pronounced when service employees had a high level of their emotion regulation ability than when thir emotion regulation ability was low. Service employees' emotion regulation ability further moderated this mediation effect of service employees' experienced customer incivility on service performance through emotional exhaustion. These findings have theoretical implications for employees' experienced customer incivility and emotion regulation ability research and provide managerial implications for practitioners. Conclusions - This study empirically elaborated the previous model of service employees' experienced customer incivility and personal resource (e.g., emotion regulation ability) literature by presenting the findings that service employees' experienced customer incivility influences their service performance via emotional exhaustion and that emotion regulation ability effectively reduces this negative effect.

Objectives The aim of this study was to examine the association between the sleep pattern, chronotype (midpoint of sleep on free days) and the depressive symptoms in adults aged 19 years and over in Korea. This study also investigated the mediating effect of perceived usual stress (PUS) and self-rated health (SRH) on the association between chronotype and depressive symptoms. Methods Among the subjects of the 7th Korea National Health and Nutrition Examination Survey (KNHANES) 2016 and 2018, 16142 adults aged 19 or over responded to the survey and finally 8604 were analyzed according to the exclusion conditions. Logistic regression analysis was conducted to see the risk of depressive symptoms, suicidal ideation over sleep pattern, chronotype. Finally, mediation analysis was performed in order to clarify how PUS and SRH are associated to chronoytpe and depression. Results After controlling for potential covariates, weekly sleep duration < 5 hours, ≥ 10 hours was associated with depressive symptoms. And late bed time sleeping after am 1:00 and later midpoints of sleep was associated with a higher level of depressive symptoms. Additionally, the PUS and SRH between chronotype and depressive symptoms showed a serial multiple mediation effect. Conclusions Short or long sleep duration, late bed time and later midpoints of sleep on free days are associated with depressive symptoms. Furthermore, the mechanism between chronotype and depressive symptoms needs to be further clarified by identifying the serial multiple mediation effects of PUS and SRH.

Purpose - The purpose of this study is to examine the effect of basic value satisfaction on service quality evaluation and customer loyalty and the moderating effect of Bargain-proneness in this process. Specifically, I analyzed the influence of basic value satisfaction, the mediating effect of service quality evaluation, and the moderated mediation effect of Bargain-proneness. Research design, data, and methodology - Data collection for this study was conducted for adults over 18 years of age with shopping experiences in traditional market within a month around the traditional market in the metropolitan area. A total of 250 questionnaire response data was obtained. Hypotheses were tested using SPSS. The PROCESS macro method was used to verify the mediating effect of the service quality evaluation on the relationship between basic value satisfaction and customer loyalty. Hierarchical regression analysis was performed to analyze the moderated mediation effect of the bargain-proneness tendency. Results - Empirical results showed that the basic value satisfaction affected service quality evaluation and customer loyalty. Specifically, it has been found that it directly affects customer loyalty and indirectly influences through service quality evaluation. The moderated mediation effect of the bargain-proneness tendency in the process of basic value satisfaction affecting customer loyalty through service quality evaluation has been verified. In other words, the higher the bargain-proneness tendency, the more influence the basic value satisfaction has on the favorable service quality evaluation. Conclusions - This study contributed to the distribution literature in that it attempted a new empirical study considering the variable 'bargain-proneness tendency', which had not received much academic attention in the past. Furthermore, this study contributed academically in that it presented important moderating variables that should be paid attention in the field of distribution studies. In this study, bargain-proneness was used with a focus on traditional markets, but this variable could play an significant role in future offline distribution studies that should pay attention to meet hedonic needs of shopping. These results suggested that traditional market practitioners should focus on the basic value and that the bargain-prone consumer segment should be considered as a target.

This study focuses on the instructor's role in student-centered learning and aims to test the effects and moderating role of instructor feedback on perceived loafing in team project-based learning. A conditional effect model including team efficacy, perceived loafing, instructor feedback, and team performance was proposed. Data were collected from students who registered for team project-based learning courses at a university in South Korea. A total of 420 cases were subjected to moderated mediation analysis. The results demonstrated that instructor feedback was negatively related to perceived loafing and moderated the relationship between team efficacy and perceived loafing. Furthermore, instructor feedback moderated the relationship between perceived loafing and team performance. In particular, even when perceived loafing was high, students who received frequent instructor feedback were found to significantly reduce the damage to team performance. Based on these findings, the importance of instructors' facilitation in team project-based learning is discussed.
