The digital business environment is rapidly evolving with advancements in information technology (IT), increasing the risk of information security incidents. Grounded in the resource-based view and in contingency theory, this study adopts a different approach from prior research by conceptualizing security management activities not as mere risk control mechanisms, but as strategic innovation drivers that can enhance corporate performance (sales revenue and operating profit). The authors develop a research model with six independent variables, including internal and external security management activities, CISO role configuration (independent or dual-role with CIO), and investment levels in IT and information security. The dependent variables include sales revenue and operating profit, with ISMS or ISO certification as a moderating variable. Using information security (IS) disclosures and financial data from 545 Korean firms that have reported their security management activities to the Ministry of Science and ICT, multiple regression and moderation analyses reveal that high IT investment negatively impacts performance, but this effect is mitigated when formal security systems, like ISMS or ISO, are in place. The results suggest that integrating recognized security frameworks into management strategies can enhance both innovation and financial outcomes, encouraging a proactive approach to security management.

Augmented Reality Smart Glasses (ARSGs) allow users to engage in picture-taking and video recording, as well as real-time storage and sharing of pictures and videos through cloud services. Unlike smartphones, newer ARSGs resemble ordinary sunglasses, allowing for unobtrusive recording. As these devices become available on an international market, it is important to understand how different cultural attitudes towards privacy and the recording and sharing of images of bystanders could impact the acceptance and adoption of ARSGs. South Korea and the United States have vastly different culturally based perceptions of photography and recording in public. S. Korea has cultural and legal restrictions in place, while the U.S.’s values of freedom of expression and individual rights are reflected in limited restrictions. Accordingly, drawing upon the Technology Acceptance Model (TAM), this paper explored the impact of privacy concerns on key constructs of the TAM for U.S. and S. Korean participants. This paper examined how Americans’ (U.S. = 402) and S. Koreans’ (S. Korea = 898) perceived usefulness, perceived ease of use, attitude toward using, and behavioral intention to use ARSGs were impacted by privacy concerns. The results of this study found that S. Korean respondents had significantly greater privacy concerns about using ARSGs than U.S. respondents. However, they also had significantly more positive attitudes and greater behavioral intentions to use ARSGs. Path analyses examining ARSGs’ acceptance revealed that privacy concerns impacted attitudes towards ARSGs, but that these had a greater impact on U.S. participants than on Koreans. The results highlight the importance of considering nuanced cultural perspectives, specifically privacy concerns, in examining the development and adoption of new technologies. Raw data and scripts for this study are available to ensure reproducibility. Full article

This study evaluates coordinate consistency in the static Korean Geodetic Datum 2002 (KGD2002) by comparing GNSS station positions derived independently from GAMIT/GLOBK and Bernese software. Using a nationwide network of approximately 3000 unified geodetic control points (UGCPs), we analyze horizontal coordinate differences (ΔN, ΔE) to identify regional patterns and potential systematic biases. The results indicate that both solutions are closely aligned with the official KGD2002 coordinates, generally within a few millimeters to sub-centimeter levels. However, small regional discrepancies are evident; for example, some provinces exhibit consistent mean northward or southward offsets on the order of 0.1–0.3 cm, and greater dispersions—up to 2 cm—are observed in peripheral regions such as Jeollanam. Notably, the Bernese solution demonstrates slightly tighter agreement, with lower standard deviations compared to GAMIT/GLOBK. The application of two distinct processing strategies within a unified static reference frame is a novel aspect of this study, revealing subtle differences attributable to network geometry, environmental factors, and software modeling approaches. The findings also underscore the limitations of KGD2002’s static nature, particularly its fixed epoch and lack of motion modeling. In response to these issues, this study discusses the rationale for transitioning to a dynamic geodetic reference frame, such as ITRF2020, to improve compatibility with international systems and account for ongoing crustal motions. Overall, the results provide a foundation for the future modernization of Korea’s spatial reference infrastructure and highlight the importance of adopting time-dependent datums in geodetic applications.

Firefighters experience high noise levels from various sources, such as sirens, alarms, pumps, and emergency vehicles. Unlike industrial workers who experience continuous noise exposure, firefighters are subject to intermittent high-intensity noise, increasing their risk of noise-induced hearing loss (NIHL). Despite global concerns regarding firefighters’ auditory health, research on Korean firefighters remains limited. This study aimed to assess personal noise exposure among Korean firefighters across three primary job roles—fire suppression, rescue, and emergency medical services (EMS)—and to predict worst-case noise exposure scenarios. This study included 115 firefighters from three fire stations (one urban, two suburban). We measured personal noise exposure using dosimeters attached near the ear following the Korean Ministry of Employment and Labor (MOEL) and International Organization for Standardization (ISO) criteria. Measurements included threshold levels of 80 dBA, exchange rates of 5 dB (MOEL) and 3 dB (ISO), and a peak noise criterion of 140 dBC. We categorized firefighters’ activities into routine tasks (shift handovers, equipment checks, training) and emergency responses (fire suppression, rescues, EMS calls). We performed statistical analyses to compare noise levels across job roles, vehicle types, and specific tasks. The worst-case exposure scenarios were estimated using 10th percentile recorded noise levels. The average 8 h time-weighted noise exposure levels varied significantly by job role. Rescue personnel exhibited the highest mean noise exposure (MOEL: 71.4 dBA, ISO: 81.2 dBA; p < 0.05), whereas fire suppression (MOEL: 66.5 dBA, ISO: 74.2 dBA) and EMS personnel (MOEL: 68.6 dBA, ISO: 73.0 dBA) showed no significant difference. Peak noise levels exceeding 140 dBC were most frequently observed in rescue operations (33.3%), followed by fire suppression (30.2%) and EMS (27.2%). Among vehicles, noise exposure was the highest for rescue truck occupants. Additionally, EMS personnel inside ambulances had significantly higher noise levels than drivers (p < 0.05). Certain tasks, including shift handovers, equipment checks, and firefighter training, recorded noise levels exceeding 100 dBA. Worst-case scenario predictions indicated that some work conditions could lead to 8 h average exposures surpassing MOEL (91.4 dBA) and ISO (98.7 dBA) limits. In this study, Korean firefighters exhibited relatively low average noise levels. However, when analyzing specific tasks, exposure was sufficiently high enough to cause hearing loss. Despite NIHL risks, firefighters rarely used hearing protection, particularly during routine tasks. This emphasizes the urgent need for hearing conservation programs, including mandatory hearing protection during high-noise activities, noise exposure education, and the adoption of communication-friendly protective devices. Future research should explore long-term auditory health outcomes and assess the effectiveness of noise control measures. Full article

Decoding motor imagery (MI) electroencephalogram (EEG) signals in the brain–computer interface (BCI) can assist patients in accelerating motor function recovery. To realize the implementation of plug-and-play functionality for MI-BCI applications, cross-subject models are employed to alleviate time-consuming calibration and avoid additional model training for target subjects by utilizing EEG data from source subjects. However, the diversity in data distribution among subjects limits the model’s robustness. In this study, we investigate a cross-subject MI-EEG decoding model with domain generalization based on a deep learning neural network that extracts domain-invariant features from source subjects. Firstly, a knowledge distillation framework is adopted to obtain the internally invariant representations based on spectral features fusion. Then, the correlation alignment approach aligns mutually invariant representations between each pair of sub-source domains. In addition, we use distance regularization on two kinds of invariant features to enhance generalizable information. To assess the effectiveness of our approach, experiments are conducted on the BCI Competition IV 2a and the Korean University dataset. The results demonstrate that the proposed model achieves 8.93% and 4.4% accuracy improvements on two datasets, respectively, compared with current state-of-the-art models, confirming that the proposed approach can effectively extract invariant features from source subjects and generalize to the unseen target distribution, hence paving the way for effective implementation of the plug-and-play functionality in MI-BCI applications.

Commercial fishing, one of the most dangerous sectors globally and, particularly, in South Korea, faces fatal accident rates significantly exceeding other industries, and an urgent improvement in safety measures is necessary to reduce these numbers effectively. The main objective of this study is to analyse fishing vessel accidents in South Korea and present the direction of safety policy for fishing vessels based on the lessons learnt from previous accidents, and, ultimately, to contribute to reduce fishing vessel accidents. For this purpose, we have analysed the marine accident data from the last five years provided by the Korea Maritime Safety Tribunal (KMST), the statistical yearbook of oceans and fisheries provided by the Ministry of Oceans and Fisheries (MOF), and the statistical survey of marine fisheries provided by the Korean Statistical Information Service (KOSIS), using both quantitative and qualitative approaches. After thorough review and analysis of the accident data, we have proposed seven suggestions for the direction of future safety policy for fishing vessels in South Korea: adopt international safety benchmarks, focus on occupational and collision accidents, tailor safety measures to vessel size and age, enhance lookout practices to prevent collisions, implement comprehensive strategies to mitigate human errors, and address communication issues among Korean and international crews.

This article delves into the history of one of the most infamous internment facilities in Korea’s recent past—Hyungje Bokjiwon (형제복지원), or Brothers Home. The article outlines the history of Brothers Home, its biopolitical production of ‘vanished lives’, and what enabled it to come into existence—arguing that this is an essential context for understanding the history of international adoption from Korea. Located in Busan, South Korea, Brothers Home began as an orphanage in the early 1960s but developed into a ‘social welfare institution’ in the early 1970s. The events that transpired from the early 1970s until the facility shut down in the late 1980s—a period which aligns with the height of international adoption from Korea—have led to some referring to this place as Korea’s ‘concentration camp’. Inmates died in the hundreds, predominantly due to malnutrition and illness, while many suffered brutal deaths through physical abuse and torture. Some of the children from Brothers Home were relocated to Western nations for adoption. The history of Brothers Home embodies the biopolitical process of bodies and lives simultaneously enveloped in and, at the same time, kept outside socio-legal frameworks to invalidate those lives or render them insignificant or invisible; to erase them from any meaningful, socio-legal context and thereby reducing those lives to bare life. The article will focus on three main areas: the history of Brothers Home, the biopolitical production of vanished lives, and how the latter resonates with specific instances depicted in testimonies written by people returning to Korea to uncover details about their adoption circumstances, that is, moments encapsulating this ‘production of vanished lives’. The central concern here is less to draw a direct line between international adoption and the events at Brothers Home, but rather to outline a crucial biopolitical context—epitomized in the history of Brothers Home—that precedes the adoption process and thus constitutes its condition of possibility. By juxtaposing this biopolitical context with autobiographical testimonies of people searching for information about the circumstances of their adoption, the article seeks to understand what it means to bear witness to the existence of a life whose desubjectivization—or disappearance—at the same time constitutes the witnessing subject’s condition of possibility.

Around 1930, the Japanese publishing market was restructured, and as part of this process, the colonial market emerged within the Japanese Empire. In an attempt to expand into the colonial market, publishers such as Kaizō-sha, Chūōkōron-sha, and Senki-sha competed among each other, producing ‘legal’ and ‘illegal’ commodities related to socialism. This paper examines the circulation of illegal commodities such as the often-banned magazine Senki (Battle Flag), cross-reading them with internal documents from Senki-sha (Senki’s publisher) and NAPF (All-Japan Federation of Proletarian Arts), as well as with those from the Japanese Home Ministry and the Japanese Government-General in Korea. By doing so, the essay argues that the main actors of the socialist cultural movement around 1930 purposefully planned to capitalize on the ‘illegal’ nature of their commodities, while adopting a public stance of differentiation from commercial capital. Furthermore, by proposing that the publication of illegal commodities was in fact deeply imbricated with the movement of capital in the publishing market, this paper also reveals that Korean-language publications–notably, the magazine Uri tongmu (Our Comrades)–produced by socialists in the Japanese interior around 1930, ended up playing a role in undermining the reconstruction of socialism in Korea. For this reason, it is crucial to reconsider the prevailing narrative about the history of the Japanese socialist movement of the late 1920s and early 1930s, which often essentializes the connection between Japanese and Korean socialists as pure ideological solidarity, paying little attention to the complex movement of capital, legal and illegal, at work in the Japanese Empire around 1930.

Both South Korea and China have collective cultures; however, there are significant differences in employee behavior due to cultural, economic, and environmental factors. This study explores the influence of organizational climate on employee innovative behavior and service performance using a competitive value model, as well as the mediating effects of social capital and organizational silence. Adopting the interpersonal relationship, rational goal, and internal process approaches, it focuses on three aspects: supervisory support, pressure to produce, and formalization. A total of 773 valid questionnaires were collected from four- and five-star hotels in South Korea and China, and the data were analyzed using SPSS and AMOS. The results showed that supervisory support and pressure to produce positively affected employee social capital, thereby affecting their service performance. Formalization positively affected organizational silence and negatively affected employees’ innovative behaviors. This study confirmed the mediating effects of social capital and organizational silence in the organizational environment. The positive effects of supervisory support and pressure to produce on social capital were similar in South Korea and China. However, among the effects of organizational silence, Korean employees were more likely to benefit from formalization. This study identified the differences in organizational climate and organizational performance between South Korea and China and provides implications for enterprises’ sustainable development.

Building Information Modeling (BIM) has been one of the most dominant trends in the construction industry worldwide. In Korea, since 2012, public construction projects worth more than USD 40 million have been subject to the application of BIM. However, many public owners have hesitated to adopt BIM for their projects; they generally view BIM as being very complex to manage and difficult to understand. In 2021, the Korean governmental entity in charge of developing the public policies to furnish quality infrastructure requested a variety of individual public owners to prepare BIM guidelines fit to the infrastructures they manage. While there are diverse BIM guides available for them to refer to in preparing the BIM guidelines, these involve certain deficiencies in meeting the public owners’ preferences, such as being tailored for the public procurement process. The main objectives of this study were to investigate the desirable nature of an owner-oriented BIM guide, suggest the structure of the guide, and identify the major advisory contents to be included in the guide. To achieve these research objectives, a number of domestic and international BIM guides were analyzed, and workshops were operated twice with 12 BIM experts from the Korean construction industry. As a result of the study, a four-stage guide structure was developed consisting of the BIM service Scoping, Tendering, Executing, and Wrapping-up (STEW) guides. Full article

South Korean universities have been facing student shortages to sustain their growth due to its severe population decline. The Korean government has since introduced policies to attract more international students to the country. The present study examined the prestige-seeking tendencies of international students in Korea and their influence on students’ satisfaction levels. The five dimensions of prestige-seeking behavior were adopted to help explain students’ satisfaction levels. Research samples were current and former international students in Korea. The findings reveal the quality of the education did not contribute directly to the students’ overall satisfaction level. Instead, it was hedonic elements that affected satisfaction. Moreover, status, snob, and bandwagon effects contributed significantly to the quality and hedonic motives. Full article

An audit team includes engagement partners, CPAs, and staff. Among them, partners play a vital role in performing tasks that require expertise and experience, such as analyzing and understanding the industry, and supervising the overall audit process. In detail, the partners establish an audit plan, determine the overall audit time, provide the audit input ratio of the engagement team, and review the audit reports. This study examines for association between the partner’s audit hour ratio and audit quality depending on the client firms’ characteristics. Although the role of partners is important, the information about partner audit hours is limited. However, the Korean government requires audit firms to disclose the partner hour information in the audit report starting in the 2014 fiscal year. By the disclosure, it is possible to examine the association between partner audit hours and audit quality. In this study, the information on partner audit hour is hand-collected from the firms’ business reports. Using 6340 observations from 2014 to 2017, the partner audit hour ratio is associated with audit quality, under the characteristics of client firms. Firms’ risks are adopted for client characteristics, and we focused on the operation of internal control. The internal control operation level is measured by the following: (1) the ratio of internal control personnel and (2) experience of the internal control personnel in the accounting and IT departments. The result suggests that for the firms where internal control is not effectively operated, partners make more effort to enhance audit quality. Full article

This study aims to shed light on determinant factors for the introduction of Government as a Platform (GaaP) by public officers who can be platform providers or main stakeholders in GaaP. It focuses on public officers in 261 Korean public agencies. In order to verify the research model’s hypotheses, we take advantage of Structural Equation Modeling and the Technology Acceptance Model. As a first result, concerning the direct effect on GaaP, the quality of open data, the scope of the stakeholders, and attitudes to civic engagement have a positive relationship on the perceived usefulness of Intelligent Information Technology (IIT). Second, in terms of the effect of IIT on GaaP, the perceived usefulness of IIT mediates positively on the intention to adopt GaaP based on the quality of open data, the scope of the stakeholders, and attitudes towards civic engagement. Based on these results, policy implications can be described as follows. Besides managing internal open data, governments should actively mine new open data that can create added value for innovation. They need to create an easily cooperative environment with other stakeholders, especially non-public participants, and governments should encourage public officers to more actively accept and utilize IIT in their jobs.

Firms have been undergoing a fundamental transformation of the Fourth Industrial Revolution, and the transformation is driven by the adoption and development of innovative technology such as big data or artificial intelligence. While the impacts of the Fourth Industrial Revolution technology on economic performance have been actively documented, Korean firm-level data indicates that still, the majority of firms have not yet utilized the Fourth Industrial Revolution technology. Hence, this study examines determinants and propensity for adopting and developing the Fourth Industrial Revolution technology. Probit model estimations show that size, internal R&D intensity, the ratio of intangible assets to the sum of intangible and tangible assets, and patent rights are positively associated with adopting and developing the innovative technology, while there are sectoral differences. Notably, a strategic alliance is the most substantial factor for the propensity of adopting and developing the Fourth Industrial Revolution technology. In sum, this study finds that not only internally accumulated intangibles and R&D investment but also active collaboration with other firms can facilitate diffusion of the Fourth Industrial Revolution technology. Therefore, building up the environment to prompt collaboration can be another effective way to accelerate transformation in addition to supporting R&D and intangible investment. Full article

This study investigates whether recognized accounts receivable (AR) factoring is more value relevant than disclosed AR factoring. After the adoption of the Korean International Financial Reporting Standards (K-IFRS), AR factoring is recognized as short-term debt, thus increasing firms’ leverage ratio. Using cross-sectional equity valuation regressions, we find that recognized AR factoring is value relevant, unlike disclosed AR factoring. Moreover, the market value of equity and AR factoring are more significantly correlated in highly leveraged firms than in less-leveraged ones. Accounting data are important from the perspective of big data. In the accounting industry as well, professionals started realizing the implications of big data. The COVID-19 pandemic has created a health crisis and wreaked havoc in an already-fragile global economy. Although there is no way to predict exactly what the economic damage from the COVID-19 pandemic will be, there must be widespread agreement that it will have severe financial impact on every company. Global financial markets have suffered dramatic falls due to the pandemic, and highly leveraged companies are in serious need of financing. While diving deeper, sound debt management and debt transparency are critical to ensure debt sustainability. Thus, companies would be willing to use AR factoring in order to overcome this financial status. This study also shows that highly leveraged firms decrease AR factoring after K-IFRS adoption.
