A random shock model for a system whose state deteriorates continuously is introduced and stochastically analyzed. It is assumed in the model that the state of the system follows a Brownian motion with negative drift and is also subject to random shocks. A repairman arrives at the system according to a Poisson process and repairs the system if the state has been below a threshold since the last repair.

Kolmogorov's forward differential equation is adopted together with a renewal argument to analyze the model stochastically. The renewal reward theorem is used to obtain the long‐run average cost per unit time.

An explicit expression is deduced for the stationary distribution of the state of the system. After assigning several costs to the system, an optimization is also studied as an example.

The present model can be used to manage a complex system whose state deteriorates both continuously and jumpwise due to the continuous wear and random shocks, such as a machine and a production line in a factory. The model can also be applied to an inventory which supplies the stock both continuously and jumpwise, such as a gas station and the distribution center for a franchise, if the continuous wear and random shocks are considered as demands for the stock.

The present model is quite complicate, however, more realistic than the previous models where the state of the system is subject to either one of continuous wear and random shocks.

This paper aims to primarily analyzing the state and pattern of current energy benchmarking progress on commercial buildings since the New York City’s energy disclosure law, Local Law 84: Benchmarking has been implemented. It then compares the yearly benchmarking progress of Leadership in Energy and Environmental Design (LEED)-certified and non-LEED-certified buildings as well as ENERGY STAR-certified and non-ENERGY STAR-certified.

For thorough analytics, the authors combined and examined four sources of data: New York City Local Law 84: Benchmarking, Primary Land Use Tax Lot Output, US Green Building Council and US Environmental Protection Agency. The data sets were combined using two primary keys: the Borough, Block, Lot (BBL) number and the building address. Four years of energy use intensity values were obtained and normalized by shrinking the range of deviance in weather.

The findings indicate a significant improvement in the benchmarking progress when controlling building size, building type, year of construction or the most recent renovation and the presence of renovation. Interestingly, there is no significant difference in the energy benchmarking progress between LEED- and non-LEED-certified buildings. Possible reasons are explored and discussed.

From a methodological perspective, the study benefited from data disclosure as well as open data sources and used secondary data with a relatively large sample size. Many studies in the construction industry are based on the case-study approach, which may affect generalizability and causality of research findings. This unique approach illustrates the potential of secondary data analysis in the industry.

The purpose of this paper is to advance our understanding of international crisis mediation by introducing and examining the nested insider-partial mediator (NIPM) concept, a nuanced perspective on IPM behavior. This study challenges the traditional view of effective mediators as external, unbiased entities by delving into the behavior and contribution of mediators who are deeply embedded in the conflict environment, such as South Korea’s unique position in navigating the US–DPRK crisis in 2017–2018. By analyzing South Korea’s dual role as mediator and negotiator and its employment of both nondirective and directive mediation strategies, the paper demonstrates the potential effectiveness of NIPMs in managing complex biases and contributing to de-escalation in intense crisis scenarios.

This paper uses a focused single-case study approach to analyze South Korea’s role as an NIPM. Using a process-tracing methodology, it examines how contextual factors such as relationships, interests and inherent biases influenced South Korea’s mediation strategies in this complex geopolitical scenario. Empirical evidence was retrieved from public sources, including official statements and press interviews, providing an empirical foundation for understanding NIPM behavior. This approach facilitates a detailed study of South Korea’s unique mediation role within the intricate dynamics of the Korean Peninsula conflict.

The study’s findings illustrate the pivotal role NIPMs can play in complex international conflicts, underlining the significant potential of NIPMs in crisis prevention. The findings highlight South Korea’s adept navigation through intricate geopolitical dynamics, leveraging its unique insider position and established relationships with both the USA and North Korea. This behavior was instrumental in mitigating a potentially explosive situation, steering the crisis toward negotiation and de-escalation. The research underscores the effectiveness of the NIPM framework in understanding the nuanced behavior of mediators who are deeply integrated into multi-level conflicts, influenced by their connections, interests and inherent biases.

This research not only broadens the theoretical framework of insider-partial mediation by introducing the concept of NIPM, but also has practical implications for policymakers and practitioners in leveraging regional mediation strategies for international crisis mitigation. The study underscores the importance of mediators’ deep-rooted connections, biases and vested interests in influencing their mediation tactics, thus offering a comprehensive understanding of the multifaceted nature of international mediation in complex geopolitical conflicts.

In recent years, many of South Korea's most prominent organizations have been involved in large‐scale frauds. These frauds have had a devastating impact on South Korean society and resulted in unnecessary suffering and high levels of unemployment for the middle class. With the aim of understanding the causes of these scandals, this paper takes an in‐depth look at the chaebol organization.

The paper takes a conceptual approach by first examining chaebols in greater detail. The paper then examines classical fraud theory, including the fraud triangle. The paper then examines chaebol organizations through the lens of the fraud triangle. By doing so, it is possible to understand why chaebols, in particular, are susceptible to fraud and corruption.

The paper provides evidence to suggest that chaebol organizations have inherent fraud risks. In order to minimize these fraud risks, chaebol organizations must address these issues.

This paper fulfills an important area of research by providing basic information about the relationship between chaebol organizations and fraud.

Although Korean sociology of sport is relatively unknown to the international community of scholars, it is a mature field in Korea. Sociology of sport was first introduced in Korea in the mid-1960s when the field first evolved in North America and Europe. However, the development of the field shows different aspects from its Western counterpart due to unique cultural and environmental factors both in academia and in society. There are three major research trends that form Korean sociology of sport. First, there is the research focus on the benefit of sport and physical activity by examining empirical data using quantitative methodologies. The second group of researchers pays attention to individual experience in diverse sport fields and utilize qualitative methodologies to investigate empirical or secondary data. The third and most recent trend is a critical approach that theoretically analyzes ideologies, power relations, and identity politics in sport and society. When looking at the future, there are problems and limitations within the field in Korea. These include lack of continuity in terms of conference sub-themes, over-production of doctoral degree graduates, conservatism rooted in the field, and a danger of regarding sport policy research as an exit for sport sociologists. However, there are also possibilities and reasons for optimism. The biggest possibility for Korean sociology of sport is globalization of the field. Another significant possibility is the need for sport sociologists in planning, developing, and evaluating sport policy. Finally, diversification of the field gives ample opportunities for future research.

This paper proposes a new theoretical framework to explain enterprise unionism and conducts the first systematic comparative study of union structure in nine Asian countries. Our framework emphasizes political dynamics and the role of the state in labor relations and argues that the initial period of the collective bargaining era constituted a critical juncture (state labor policy) that occurred in distinctive ways in different countries and that these differences played a central role in shaping the different union structures in the following decades. The nine countries are mainly divided into three groups, depending on the type of state labor policy: enforcement of enterprise unionism; centralization/laissez-faire (non-enterprise unionism); and dual unionism/gradual transition (middle-ground). Governmental data were used for the study. A clear correspondence between state labor policy and union structure in each of these groups was found. We believe that our framework significantly enhances our understanding of the Asian cases. Future research should explore the validity of the proposed framework through comparative studies of Latin American cases where enterprise unions have also been observed.

The purpose of this paper is to explain Japan’s role in the peace process on the Korean Peninsula that began in early 2018.

This paper emphasizes the historical context of international politics in Northeast Asia, rather than power politics or geopolitics. The paper reaffirms the significance of the ongoing peace process on the Korean Peninsula by considering a synthesis of three joint declarations published in 1998, 2000 and 2002 between the Republic of Korea (ROK) and Japan, the ROK and Democratic People’s Republic of Korea (DPRK), and between the DPRK and Japan.

The normalization of diplomatic relations between DPRK and Japan, along with reaffirmation of the joint declaration between the ROK and Japan, and the Panmunjeom Declaration, would be a base for denuclearizing Northeast Asia.

In Northeast Asia, historical reconciliation among the two Koreas and Japan and peace-building between the two parties on the Peninsula are closely linked. Moreover, the three bilateral relationships among these three parties are also the basis for creating a new multilateral security order in Northeast Asia.

This paper explores how gender-related issues are communicated in Korean family-run conglomerates (chaebols) and the roles of women within these businesses. It also addresses to what extent the communication of chaebols about female employment and career development reflects the perception of gender representation in these organisations.

By paying attention to gendered discourse in Korean chaebols, this paper examines what is said and written about gender issues in glottographic statements (texts) and non-glottographic statements (charts and other visuals) of annual reports (ARs) published by five chaebols since 2010. The paper uses a Foucauldian framework to develop the archive of statements made within these ARs.

Although there is an increase in female-employee ratios, ARs show that number of women at the board or senior management level continue to be small. ARs tend to provide numbers related to female employment and retention in their non-glottographic statements, yet these numbers occasionally differ from and frequently are not explained by glottographic statements. The strategies used by chaebols to improve career prospects for their female staff are only vaguely described and rarely evaluated.

This paper looks beyond the existing discourse analysis on “talk and text” by also investigating claims made through graphic and linear/pictorial elements and their interplay with text. This approach opens new understandings of how gendered discourses are constructed and how they (unintentionally) fail to resolve issues and perceptions related to female employment and career development in Korea.
