Genome Resources for Identifying SNPs Associated With Eight Horticultural Traits in Commercial Korean Elite Radish (Raphanus sativus) Lines

ABSTRACTRadish (Raphanus sativus), which belongs to the family Brassicaceae, has relatively limited genomic resources, especially for elite lines used in commercial breeding and other agricultural applications. Thus, this study aimed to provide a comprehensive catalogue of genome sequences for 100 elite radish lines used in the Korean industry for commercial breeding purposes. These lines were sequenced and mapped to the elite Bakdal genome. A total of 33,919 high‐quality single nucleotide polymorphisms (SNPs) were identified and were found to be associated with eight distinct phenotypic traits. Five diverse machine learning (ML) models revealed that a subset of 198 SNPs had high predictive potential for the eight horticultural traits. Furthermore, the 100 elite lines were grouped into four clusters based on the eight traits, and their predictive potential was evaluated using the ML models trained using both individual and pooled SNPs. The accuracy ranged from 0.83 to 0.96 for the individually trained models and from 0.84 to 0.95 for the pooled models. This study provides a substantial basis for the advancement of digital/precision radish breeding.

Comparison of the Competitiveness of Chinese and Korean Cultural Industries Based on the Perspective of New Institutional Economics

Based on the perspective of new institutional economics, this paper compares the competitiveness of the cultural industries in China and South Korea, and analyses the similarities and differences between the two countries in terms of the institutional environment, market structure and business cases. By sorting out the theoretical framework of new institutional economics, it explores the influence of factors such as property rights system, transaction costs and cultural industry efficiency on the development of cultural industry. China's cultural industry has advantages in terms of policy support and market scale, but the problems of insufficient intellectual property protection and imperfect market mechanism still restrict its international competitiveness. In contrast, South Korea's cultural industry is known for its mature market mechanism, strong content creation ability and effective intellectual property protection, which has successfully promoted the global spread of the "Korean Wave" culture. Through case studies of typical enterprises such as Tencent and YG Entertainment, the differences in competitiveness between the two countries' cultural enterprises in the international market are revealed. Finally, puts forward suggestions to optimise the institutional environment, strengthen international cooperation and promote cultural innovation, so as to promote the sustainable development of the cultural industries in China and South Korea. The research in this paper provides theoretical basis and empirical support for an in-depth understanding of the development mode and international competitiveness of Chinese and Korean cultural industries.

Evolution to entrepreneurial hospital led by open innovation: A case of Korean hospital industry

The role of hospitals as leaders of innovation in the bio health industry is emerging in the bio health industry. Hospitals are evolving from medical treatment-centered traditional hospitals to innovation-centered entrepreneurial hospitals that focus on research and development (R&D), and technology commercialization. A series of commercialized medical technologies by clinicians in hospital turns into business models in collaboration with firms. However, few studies have attempted a practical approach to entrepreneurial hospitals. Therefore, this study aims to explore the transformation of traditional hospitals to entrepreneurial hospitals through Korean hospital cases. This study studied the Korean government's initiatives related to supporting entrepreneurial hospitals. In addition, this study conducted interviews with key stakeholders involved in hospital-based innovation networks. Korea has been promoting entrepreneurial hospitals based on open innovation since 2004, and various government-supported projects have been carried out in parallel, making it suitable for examining the development trajectory and challenges from a research perspective. The findings of this study provide a theoretical framework for research on hospital-based open innovation.

Optimal preventive maintenance: Balancing reliability and costs in the electricity market

This study addresses the challenge of achieving optimal preventive maintenance within power systems, aiming to balance reliability and costs effectively. The primary focus is on understanding the relationship between preventive maintenance expenditures and the failure rate of essential transmission components, particularly transformers in substations. We contribute to the existing literature by providing two key insights. Firstly, we establish a theoretical framework for determining the optimal level of preventive maintenance, which can be extended across various electricity facilities. By analyzing the relationship between preventive maintenance costs and failure rates, our goal is to identify the investment level that ensures a reliable power system while minimizing financial burdens. Secondly, we explore the functional form that accurately characterizes the link between preventive maintenance costs and failure rates. The diminishing marginal rate of failure, dependent on different functional forms, highlights the variability of optimal preventive maintenance expenses. Utilizing Lasso regression, we identify the functional form that optimally characterizes the relationship between outage occurrences and maintenance costs. These insights extend well beyond the confines of the Korean power industry, offering a sustainable approach to managing transmission facilities and enhancing the overall stability and efficiency of global electricity networks.

Developing a Dynamic Feature Selection System (DFSS) for Stock Market Prediction: Application to the Korean Industry Sectors

For several years, a growing interest among numerous researchers and investors in predicting stock price movements has spurred extensive exploration into employing advanced deep learning models. These models aim to develop systems capable of comprehending the stock market’s complex nature. Despite the immense challenge posed by the diverse factors influencing stock price forecasting, there remains a notable lack of research focused on identifying the essential feature set for accurate predictions. In this study, we propose a Dynamic Feature Selection System (DFSS) to predict stock prices across the 10 major industries, as classified by the FnGuide Industry Classification Standard (FICS) in South Korea. We apply 16 feature selection algorithms from filter, wrapper, embedded, and ensemble categories. Subsequently, we adjust the settings of industry-specific index data to evaluate the model’s performance and robustness over time. Our comprehensive results identify the optimal feature sets that significantly impact stock prices within each sector at specific points in time. By analyzing the inclusion ratios and significance of the optimal feature set by category, we gain insights into the proportion of feature classes and their importance. This analysis ensures the interpretability and reliability of our model. The proposed methodology complements existing methods that do not consider changes in the types of variables significantly affecting stock prices over time by dynamically adjusting the input variables used for learning. The primary goal of this study is to enhance active investment strategies by facilitating the creation of diversified portfolios for individual stocks across various sectors, offering robust models and feature sets that consistently demonstrate high performance across industries over time.

일본 손해보험산업의 재무성과 분석에 관한 연구

Purpose: This study examines financial performance of the Japanese non-life insurance industry comparing USA and Korean non-life insurance industry by using the A.M. Best’s rating technique. We also aim to contribute to an improved understanding of the relationship between growth, efficiency, profitability, safety, and liquidity in Japanese non-life insurance industry. Research design, data, and methodology: We conduct factor analysis to measure the validity of key variable factors of property-liability insurers in Japan, USA, and Korean for the 2010 to 2019 time period. After factor analysis, we also calculate total score of each non-life insurance industry and compare total scores without weighting value by using principal component analysis. Also, we analyze the relationship among these variables and the interdependence between profitability and safety by using a multiple linear regression analysis. Implications: Three findings are highlighted as follow: First, the correlation coefficient in the Japan general insurance industry represents the linear relationship between variables. It can be seen that profitability has a positive relationship with growth of the premium, asset size of the Japanese non-life insurance industry, and liquidity and it has a negative relationship with safety and efficiency. The highest correlation among the variables occurs between profitability and safety because less profitable insurers are more willings to take risks. Second, there is strong relationship between profitability and safety, which is signifiant at 0.01 level in the Japan general insurance industry. We conclude that insurers with a higher solvency ratio should show a better profitability than other peers. Finally, Japan non-life insurance has good level of efficiency, safety, and liquidity, the growth and profit performance shows the margin(below) of average level, it should improve profitability and growth areas in order to take comparative advantages in a competitive global general insurance industry.

Effects of gender and slaughter age on physicochemical and quality traits of Korean Hanwoo striploin.

Hanwoo beef is in high demand because of its unique flavor, freshness, and high-fat content. However, the longer rearing period required to enhance marbling in Hanwoo cattle has adverse environmental consequences, such as greenhouse gas emissions and overall rearing costs. To address consumer preferences for leaner and healthier meat, the Korean meat industry has recently introduced Hanwoo heifer meat as an alternative source, but its quality traits are still unclear. Nevertheless, there is a limited body of research exploring the impact of Hanwoo gender (steer, heifer, and cow) and their corresponding slaughter ages on meat quality traits. This study looked into how gender affected the physicochemical and qualitative features of Hanwoo striploin at their respective slaughter ages. Results revealed that cow striploin has higher levels of moisture (66.81%) and protein (20.76%), whereas it contains lower levels of fat (10.66%) and cholesterol (34.66 mg/100 g). Regarding the physicochemical properties, cow striploin exhibited significantly lower shear force, color indexes, and soluble collagen (p < 0.05). However, chondroitin (1.19%) and muscle fiber area (1,545.23 μm2) were significantly higher in steer striploin than in heifer and cow (p < 0.05). Cow striploin exhibited significantly higher levels of oleic acid, unsaturated fatty acids (UFAs), and monounsaturated fatty acids (MUFAs) while having lower levels of eicosadienoic acid and atherogenic index compared to the other two groups. Cows and heifers had higher concentrations of amino acid metabolites than striploin from steers. Furthermore, bioactive metabolites such as carnitine and carnosine content were found higher in cow and heifer respectively. Overall, Hanwoo cattle gender influences the qualitative attributes of striploin; nevertheless, compared to steer and heifer striploin, cow striploin is a relatively good source of protein, fatty acid content, and metabolites conducive to a healthy diet.

Determinants Influencing Korean Agri- Food Companies’ Modes of Overseas Market Entry

Purpose - Faced with the constraints of a limited domestic market, the Korean agri-food industry necessitates regional diversification through the establishment of offshoring production subsidiaries. This study tests the validity of Root’s model of the determinants of offshoring and sequential entry to overseas markets on Korean agri-food companies’ offshoring of production subsidiaries. Design/Methodology – This study employs the convergent mixed-methods research design, wherein qualitative and quantitative data collection and analysis are conducted, then compared, before interpreting the data affecting Korean agri-food outward direct investment (ODI). Methodologically, based on Korean agri-food manufacturing company ODI data from the KOTRA, a survey was conducted to quantitatively analyze the factors influencing their selection of production subsidiaries for ODI. Findings – Though Korean agri-food companies also consider Root’s external factors when selecting overseas entry methods, the sequential entry route and selection model, factors theorized to influence Root’s overseas market entry method, were not found to be statistically significant. Instead, they tailor their market entry approach based on the type of investment and the operating objectives of the local subsidiary. This is attributed to Korean agri-food companies’ deviation from sequential entry routes when entering markets through ODI, as well as the determination of the form and type of investment of these overseas subsidiaries according to the purpose of their operations. Originality/value - This study distinguishes itself by employing a convergent mixed-methods design, which combines quantitative and qualitative analyses to identify the determinants of ODI market entry by Korean agri-food companies. Furthermore, it evaluates Root’s market entry model from the perspective of Korean agri-food companies.

The Accomplishments of KoCVAM in the Development and Implementation of Alternative Methods in Korea.

The Korean Center for the Validation of Alternative Methods (KoCVAM), which promotes the Three Rs principles and the use of alternative methods in Korea, has been operating within the Toxicological Screening and Testing Division of the Ministry of Food and Drug Safety (MFDS) since 2009. KoCVAM has exchanged opinions and information on the development and validation of non-animal alternative test methods as part of the International Cooperation on Alternative Test Methods (ICATM), and provided input into draft OECD Test Guidelines (TGs). Several Korean laws (e.g. the Cosmetics Act) encourage the use of alternative test methods for chemical testing and assessment. To promote and support the use of alternative test methods in the country, KoCVAM has published information and provided training on the national guidelines, which are based on the OECD TGs. In addition, KoCVAM has held annual training workshops on alternative test methods, to help Korean research institutions (including GLP test facilities) to implement them. In addition, by helping to develop and validate alternative test methods that were adopted in OECD TG 442B, TG 492 and TG 439, KoCVAM has contributed to the enhanced competitiveness of Korean industry on the worldwide stage.

Türkiye-Japan FTA and Türkiye’s Changing Economic Relations with the East Asian Economies

Türkiye has always run a large trade deficit against Japan due to the low value-added and technology contents of its export products and the very high technology content of Japanese export products. Japan was not viewed as a major trading partner considering that around six-tenths of Turkish exports were destined for Europe. However, some industrial products such as electronic machines and motor vehicles were essential not only for consumption but also for industries as inputs. In Türkiye’s trade with East Asia, Japan dominated its position as the major trading partner of Türkiye in the region. During the early 2000s, Japan lost its top position first to China and then second position to Korea, dropping to the third rank. The decreasing importance of Japan in Türkiye’s trade with East Asia reflects the demise of Japanese industries which have been losing competitiveness against Korean and Chinese industries. Recently, a free trade agreement (FTA) has been proposed between Türkiye and Japan. The negotiations started in 2014 but are yet to be completed due to disagreements about opening up the agricultural sector in Japan and other trade[1]related issues. The proposed FTA is expected to improve the ailing trade relations between Türkiye and Japan. In this paper, we evaluate the trade relations between the two countries, in conjunction with the rise of China and Korea in Türkiye’s trade, by a careful comparison of trade statistics and a simulation analysis using a computable general equilibrium model.

Abstract 838: Population attributable fraction of occupational carcinogens for cancer incidence among Korean adults in 2020

Abstract Assessing the level and scope of exposure to occupational carcinogens on a country-specific basis presents challenges, and as a result, it has been appraised as uncertain when compared with other factors in the estimation of the burden of cancer. The Korean CARcinogen Exposure (K-CAREX) developed in 2021 is utilized to estimate the population at risk in industrial work environments in Korea (Koh et al., 2021). Our goal is to estimate preventable cancer incidence attributable to occupational carcinogens in Korea, utilizing the K-CAREX program and employing appropriate methodology. Among the exposures classified as Group 1 factors by IARC, considering the possibility of occupational exposure. Population attributable fractions (PAFs) were computed using Levin's Formula (1953), considering a latency period of 15 years between exposure and cancer in our assessment. The prevalence of exposure was calculated using K-CAREX program and census data. The relative risk (RR) for incidence was derived from a meta-analysis of literature. It was possible to calculate PAFs for 11 occupational factors linked with 8 cancer types. This estimation was chosen based on a combination of exposure and sufficient evidence of human carcinogenicity. As a result, Population attributable fractions (PAFs) for cancer incidence associated with occupational carcinogens was estimated at 1% in 2020. Lung cancer (approximately 90%) was found to be the most prevalent type of cancer attributable to occupational factors, as widely acknowledged. The prevalence of exposure to occupational carcinogens was 22%, with Diesel engine exhaust being the most significant source for both genders. Since the early 2000s, the exposure levels of asbestos, subject to usage prohibition and restriction measures, were estimated to be at a lower level compared to other countries. It is evident that these estimates reflect the characteristics of the Korean industry. This is anticipated to provide a foundation for the development of methodologies and indicators essential for measuring the burden of occupational cancer in the country.

Naeseon Ilche and Nazi medievalism: making nation, history, and film

ABSTRACT The present study aims to compare the cinematic propaganda of colonial Korea and Nazi Germany, revealing how the two countries used film to construct narratives of nationalism. Furthermore, this study will aid our recognition and understanding of the similarities and differences between victims and aggressors in spreading nationalist propaganda. Despite the similarities between the colonial Korean and Nazi German film industries in spreading nationalist propaganda, there are significant differences between these two countries’ ways of promoting national values: the colonial Koreans adopted transcolonial nationhood (i.e. the strategy of integrating nations), whereas the Nazis excluded minorities, such as Jews. Therefore, dichotomous evaluations of the victim and the aggressor are inconsistent with existing standard interpretations. Colonial Korea, generally known as having experienced the trauma of colonization, also engaged in cinematic fabrication and the weaponization of history, as Nazi Germany did. Propaganda films in both colonial Korea and Nazi Germany played a significant role in reconstructing their national identities. Regarding the cinematic reinvention of these national identities, we should eschew the artificial dichotomy between victims and aggressors.

Characterization of the life cycle carbon footprint of the automobile industry in the Republic of Korea by environmentally extended input-output model

The automobile industry is a major economic driver in Republic of Korea (Korea). However, little is known about its climate change contribution. This study estimates the direct and indirect greenhouse gases (GHG) emissions of the Korean automobile industry for the first time, by using a 2017 environmentally extended input-output (EEIO) model integrated by energy balance, GHG inventory and input-output table of 2017. The results show that the final demand of Korean automobile industry led to 8.4% of national GHG emissions in 2017, mostly because of indirect emissions embodied in the supply chain. The study also found that the Scope 1, Scope 2 and Scope 3 emissions on average accounted for 3.0%, 2.9%, and 94.7%, respectively. This highlights the contribution of the upstream supply chain such as primary metals (40.9%) and electricity (32.5%) when assessing the GHG emissions. Finally, the study underscores that carbon taxes could have a significant impact on the competitiveness of automobile export. Overall, this study provides valuable insights on countermeasures by identifying the GHG emissions characteristics of the automobile industry. The results of the study could be used to develop policies and strategies to reduce the GHG emissions and promote sustainable practices in the Korean automobile industry.

Implications of the Carbon Border Adjustment Mechanism on South Korean industries: Challenges and policy recommendations

This study examines the effects of the European Union's Carbon Border Adjustment Mechanism (CBAM) on South Korean industries. Concerns about carbon leakage, where carbon emissions increase in countries or regions with less stringent climate policies, have grown recently. Specifically, firms strategically relocate their operations to countries with lower carbon costs, where they can produce goods more cheaply and without carbon constraints. CBAM is a carbon tariff on carbon intensive products imported by the European Union. While the CBAM has the potential to reduce global carbon emissions, it poses significant risks to South Korea, which relies heavily on exports of CBAM-affected products. This study provides an overview of the potential effects of the CBAM on industries in South Korea, applies event study analysis to quantitatively evaluate how the financial market has reacted to CBAM-related events. Based on the research findings, as the details of CBAM become clearer, there is a shift in perception from environmental goals to broader issues across industries. Building on this understanding, we discuss issues related to the CBAM enactment: firm-level carbon accounting, EC-certified accreditation institutions, and the carbon allowance price gap between the EU and South Korea. We propose necessary short-term and long-term policies to attenuate CBAM-related risks.
