Electronic waste is always a big problem when it comes to the disposal of electronic appliances, and they pose a significant threat ecologically. New technology replaces the existing one, and the older one is discarded. Biodegradable electronics, as an emerging research area, gives viable solutions to the problem of E-waste. It mainly deals with the development of transient electronic devices, i.e., getting decomposed gradually or dissolvable in an eco-friendly way when their purpose has been achieved. This paper presents a scientometric analysis of the research in biodegradable electronics by employing a Scopus database of more than 1109 research articles, conference papers, review papers, and books published on this topic. This study is done over two decades of data from 2003 to 2023 on biodegradable electronics. It describes the trends and future of the research area using keyword analysis, citation network, and bibliometric tools. The study of the number of papers shows a 68%, 75%, and 55% increase in research articles, conference papers, and review documents in 2022. The country-wise contribution to the research shows that China, the USA, India, and South Korea are the major contributing nations. China is the most productive nation, with 297 publications. This paper reveals that the research area has increased the interest of researchers, and countries are collaborating to achieve sustainable development goals. The bibliometric analysis identifies various challenges to biodegradable electronics, such as degradation diversity, integration, fabrication and scalability. Based on these, the future aspects of biodegradable electronics are identified in organic bioelectronics, soft electronics, novel fabrication mechanisms, and Innovative chemistry for green electronics. This study will aid academia, researchers and government agencies in exploring biodegradable electronics with multifaceted society-wide applications. [ABSTRACT FROM AUTHOR]

Recently, papers with multiple corresponding authors (co-correspondence) are frequently noticed in scientific journals. This is a trend that parallels a significant increase in research collaboration, but its rapidity raises concern about whether the legitimacy and value of the corresponding authorship are changing or even damaged. This study investigated how extensive and sound the trend of co-correspondence in science and engineering is. The increasing trend of co-correspondence papers was confirmed by examining SCOPUS index (www.scopus.com) for the papers published by scholars of the USA, Japan, South Korea, and China in 2008-09 and 2018-2019. The number of co-correspondence papers indeed increased in all four countries. However, the numbers varied significantly among the countries, markedly higher in South Korea and China cases, which also showed far higher numbers of the papers with a co-corresponding author who is the only member from his group. To dig into reality, South Korean scholars were surveyed with questionnaires regarding the trend of co-correspondence. Over 64% of respondents answered that they had participated in papers where multiple corresponding authors are listed, and 22% of them thought that the co-corresponding author did not play his due role and the co-corresponding authorship was exchanged between friends or given as a courtesy for various reasons. Although corresponding authorship allocation is majorly a concern for journal editors, a trend of inappropriate practices or misuse of co-corresponding authorship calls for local and global academic community awareness.

Strontium (Sr) is an element of toxicological concern due to its close chemical proximity to Ca. In this work, Sr in sea salts collected from China and South Korea was analyzed by laser‐induced breakdown spectroscopy (LIBS). The precision could be improved by using multiple filter‐paper sampling and intensity normalization using a weak Na I line as a reference signal. The analyte signal variation between filter‐paper pieces as well as that within a single filter‐paper piece could be corrected by the suggested method. The limit of detection of ~2 ppm and the precision of ~5% could be obtained. As a measure of accuracy, the root‐mean‐square error was estimated to be 9 ppm. The multiple filter‐paper sampling can be performed easily on the salt production sites and improves the LIBS analysis precision resulting to sufficient quantification capability for minor metallic elements in edible sea salt products.

Background We previously showed that the number of publications in dermatology is increasing year by year, and positively correlates with improved economic conditions in mainland China, a still developing Asian country. However, the characteristics of publications in dermatology departments in more developed Asian countries such as Japan and South Korea are unknown. Methods In the present study, publications from 2003 through 2012 in dermatology in Japan, South Korea and mainland China were characterized. All data were obtained from www.pubmed.com. Results Dermatology departments in Japan published 4,094 papers, while mainland China and South Korea published 1528 and 1,758 articles, respectively. 48% of articles from dermatology in Japan were original research and 36% were case reports; The number of publications in Japan remained stable over time, but the overall impact factors per paper increased linearly over the last 10 year period (p < 0.05). In mainland China, 67% of articles from dermatology were original research, while 19% were case reports; The number of publications and their impact factors per paper increased markedly. In South Korea, 65% of articles from dermatology were original research and 20% were case reports. The impact factors per paper remained unchanged, despite of the fact that the number of publications increased over the last 10 year period (r2 = 0.6820, p = 0.0032). Only mainland China showed a positive correlation of the number of publications with gross domestic product per capita during this study period. Conclusions These results suggest that the total number of publications in dermatology correlates with economic conditions only in developing country, but not in more developed countries in Asia. The extent of economic development could determine both the publication quantity and quality. [ABSTRACT FROM AUTHOR]

Traditional wisdom on how late industrialized countries follow the technology trajectories of preceding economies is in need of reformation as these countries have attained industrial leadership in a growing number of fields. However, current understandings about these countries' development of their emerging technologies have yet to investigate the divergence of idiosyncratic technology trajectories. The aim of this paper was to explore how their knowledge production strategies in emerging technology sectors are diverging. Specifically, this research examines the changing patterns of knowledge production in quantum technology in South Korea and China by developing a knowledge portfolio and knowledge strategic diagram. According to the knowledge portfolio, the relative literature position differs. In the knowledge strategic diagram, there are diverging patterns in the emerging keywords sector. This paper contributes to the literature by demonstrating the diverging strategies of late industrialized countries in their transition from catch‐up to post‐catch‐up paradigms and provides policy implications for countries developing an idiosyncratic trajectory in emerging technology sectors.

The entertainment industry is driven to sell certain commodities transnationally, particularly in a world where borders are becoming increasingly diffused through the access afforded by the Internet. Media content is easily consumed, making cultural exporting fast and easy. Similar tropes and plot have been replicated in the East Asian film and TV industry, perhaps in hopes of replicating the success. This paper looks at the manufacture of ideal masculinities within East Asia, particularly China. From ex-members of K-pop group EXO to the successful TV series, cross-influence of East Asian popular culture is prominent. Through this paper, I look at the influence of K-dramas on the Chinese TV industry and particularly the manufacturing of a militarized masculinity on Chinese TV. Far from portraying brute and fearsome soldiers, ideal masculinity on TV is portrayed as "steely exterior but gentle internally" and thus desirable romantic partners to heterosexual women. By exploring the basic conception of Chinese masculinity, I then discuss representations of militarized masculinity on the silver screen (Wolf Warrior II) and C-dramas, with particular focus on the series, You Are My Hero (2021).

This proposed work aims to understand the Korean Academic Circle (KAC)'s research trend on the "One Belt One Road" (OBOR) by employing a quantitative analysis of the recent research articles published by the KAC. To do so, this proposed research has used the well-known network analysis software, Ucinet 6, by which the papers on related topics are collected and filtered from Korea Citation Index. To perform the analytical selection, the proposed work has chosen 'keywords' as the core research object and performed analysis from transverse to longitudinal aspects, and from holistic to individual aspects, respectively; and from this, the KAC's research trend on OBOR is derived. The present work has established that the KAC's attention is continuously increasing on OBOR and has sustainability. Centered on the OBOR, Korean researchers have spread their studies in various dimensions ranging from the issues like China's political economy to Sino-Korea economic and trade exchanges, and so on. The KAC has even combined OBOR with Korea's international development initiatives, which can help Korea benefit from active and sustainable cooperation with China. Moreover, the proposed work has found that Korean researchers have also actively expressed their growing attention, highlighted Korea's interest, and showed concern about China hegemony and Sinocentrism in their recent documented research works.

During the Ming Dynasty, China and Korea exchanged frequently and recorded a large amount of written information, which is of great value for understanding the culture of that time. The large amount of data makes it difficult to conduct quantitative analysis by researchers, which makes the analysis limited. This paper carries out a research on the cognition and analysis method of Chinese and Korean envoys to foreign cultures in Ming Dynasty based on big data analysis technology. Based on the literature research, this paper determines the ontology model establishment method to efficiently detect the written records of Chinese and Korean envoys in Ming Dynasty. The established ontology model and the improved clustering analysis method can improve the efficiency of data detection, reduce the error of data detection, and provide data basis for the research of this paper. According to the technology of big data analysis, this paper analyzes the focus and status class of Chinese and Korean envoys in Ming Dynasty and analyzes cognition of the Chinese and Korean envoys for the foreign culture. The results show that the envoys of the Chinese and Korean pay different attention to the foreign culture due to their different cognition of the foreign culture, compared with Ming Dynasty envoys, Korean envoys paid 15.3 percent less attention to geography, 19.7 percent more to history, 11.7 percent more to people, and 16 percent less to customs. This reflects the two envoys' different perceptions of the foreign culture. And the status class of the envoys exacerbates this difference. In the early Ming Dynasty, the creative diversity of Ming envoys was far lower than that of Korean envoys. As time went by, the creative diversity of Ming envoys increased. The results provide support for further understanding of Chinese and Korean culture and their relationship in Ming Dynasty. [ABSTRACT FROM AUTHOR]

Alibaba and Coupang had enjoyed a period of success, starting with their IPOs. However, both companies have underperformed Amazon during the last 12 months. This special issue explores the underlying drivers for their tumultuous performance outcomes, including governance, political risks and internationalization strategies. This introduction paper sets the scene by studying the market perspective based on analyst reports, financial statements and stock market data. To understand growth expectations, we decompose current share prices into their present value, explained by current earnings and future value, driven by future growth and profitability. Exogenous factors such as the recent increase in interest rates, woes of governance problems associated with foreign corporations in South Korea and China's anti-monopoly drive aimed at its tech giants have contributed to weaker performance. Our analysis of implied growth rates suggests that the market expects annual revenue growth above 11% for the foreseeable future. These expectations will be hard to meet, requiring a rethink of business models and processes. [ABSTRACT FROM AUTHOR]

In recent years, the world's free trade system has been severely damaged by a series of protectionist measures in the United States and anti-globalization practices such as Brexit. Against this background, RCEP, the world's largest trade agreement, was officially signed on November 15, 2021. The RCEP provided a good working basis for the establishment of a Korea, China, and Japan free trade zone. First, this paper describes the current status of Korea-China-Japan trade cooperation and the current status of the trilateral telecommunication industry. Second, this paper simulates the changes in the overall economy of China, Japan, and Korea when tariffs are reduced to 0%, 5%, and 10%, respectively, after the establishment of a free trade zone using the 8th edition GTAP database. Then, using the simulated data changes and using the 2019 data as a benchmark, we calculated the changes in the RCA index for the three countries' telecommunications industries for the three tax rates. In the end, it is concluded that the economies of the three countries will grow to different levels in many ways when the Korea, China, and Japan free trade zone is established. Japan's telecommunications industry will not be significantly affected, Korea will grow significantly with higher tax rates and China will grow significantly with lower tax rates.

Background: Mild cognitive impairment (MCI) is commonly defined as a transitional subclinical state between normal aging and dementia. A growing body of research indicates that health behaviors may play a protective role against cognitive decline and could potentially slow down the progression from MCI to dementia. The aim of this study is to conduct a bibliometric analysis of literature focusing on health behaviors and MCI to summarize the factors and evidence regarding the influence of health behaviors on MCI. Methods: The study performed a bibliometric analysis by retrieving publications from the Science Citation Index and Social Sciences Citation Index subdatabases within the Web of Science Core Collection. Utilizing VOSviewer and CiteSpace software, a total of 2,843 eligible articles underwent co-citation, cokeywords, and clustering analyses. This methodology aimed to investigate the current status, trends, major research questions, and potential future directions within the research domain. Results: The bibliometric analysis indicates that research on healthy behaviors in individuals with MCI originated in 2002 and experienced rapid growth in 2014, reflecting the increasing global interest in this area. The United States emerged as the primary contributor, accounting for more than one-third of the total scientific output with 982 articles. Journals that published the most articles on MCI-related health behaviors included "Journal of Alzheimer's Disease," "Neurobiology of Aging," "Frontiers in Aging Neuroscience," and other geriatricsrelated journals. High-impact papers identified by VOSviewer predominantly cover concepts related to MCI, such as diagnostic criteria, assessment, and multifactorial interventions. Co-occurrence keyword analysis highlights five research hotspots in health behavior associated with MCI: exercise, diet, risk factors and preventive measures for dementia, cognitive decline-related biomarkers, and clinical trials. Conclusion: This study provides a comprehensive review of literature on health behavior in individuals with MCI, emphasizing influential documents and journals. It outlines research trends and key focal points, offering valuable insights for researchers to comprehend significant contributions and steer future studies. [ABSTRACT FROM AUTHOR]

Objective: The study aims to assess the current development status of transforaminal full-endoscopic spine surgery (TFES) by exploring and analyzing the published literature to obtain an overview of this field and discover the evolution and emerging topics that are underrepresented. Methods: Using Bibliometrix, CiteSpace, and VOSviewer, we analyzed the bibliometric data selected from the Web of Science Core Collection between January 2002 and November 2022. The descriptive and evaluative analyses of authors, institutes, countries, journals, keywords, and references are compiled. The quantity of research productivity was measured by the number of publications that were published. A quality indicator was thought to be the number of citations. In the bibliometric analysis of authors, areas, institutes, and references, we calculated and ranked the research impact by various metrics, such as the h-index and m-index. Results: A total of 628 articles were identified in the field of TFES by the 18.73% annual growth rate of research on the subject from 2002 to 2022, constituting the documents are by 1961 authors affiliated with 661 institutions in 42 countries or regions and published in 117 journals. The USA (n = 0.20) has the highest international collaboration rate, South Korea has the highest H-index value (h = 33), and China is ranked as the most productive country (n = 348). Brown univ., Tongji univ., and Wooridul Spine represented the most productive institutes ranked by the number of publications. Wooridul Spine Hospital demonstrated the highest quality of paper publication. The Pain Physician had the highest h-index (n = 18), and the most cited journal with the earliest publication year in the area of FEDS is Spine (t = 1855). Conclusion: The bibliometric study showed a growing trend of research on transforaminal full-endoscopic spine surgery over the past 20 years. It has shown a significant increase in the number of authors, institutions, and international collaborating countries. South Korea, the United States, and China dominate the related areas. A growing body of evidence has revealed that TFES has leapfrogged from its infancy stage and gradually entered a mature development stage. [ABSTRACT FROM AUTHOR]

Purpose: This conceptual paper aims to explore under what conditions multinational companies (MNCs) are more likely to internationalize through externalization modes. Design/methodology/approach: This paper complements previous studies by proposing three industry-specific factors that affect MNCs' decision for externalization. It then applies this framework to the case of Korean MNCs' strategic choice when entering the Chinese film market which is highly regulated by the government, to illustrate how such a framework works in practice. Findings: This paper suggests that MNCs are more likely to choose externalization entry modes under the three industry conditions: when the business grows fast, when there are best practices of industry standard and when the business requires multi-competence. It also shows that the three conditions explain well the growing Korea–China co-productions in the Chinese film market. Practical implications: This paper provides useful implications for the government's regulatory effectiveness. The protectionist policies of the host government are valid only in an industry where the three conditions are met, as they increase the possibility of domestic firms' participation by encouraging foreign MNCs to shift their entry mode from sole venture toward alliances with domestic firms. Originality/value: This paper enriches the entry-mode research by indicating that MNCs' externalization decisions need to consider these industry-specific factors. In addition, it also contributes to the understanding on why some countries maintain their high attractiveness for foreign MNCs, whereas other countries do not, given the similar level of restrictive government regulations.

With the acceleration of economic globalization, the development of aviation logistics plays an increasingly significant role in the logistics industry. As the foundation of aviation logistics development, airport terminals are attracting increasing attention. In this respect, the aim of this research is to analyze 65 academic papers on Chinese airport terminals from 2003 to 2020 by utilizing analytic keywords of academic papers and suggest the research trend of Chinese airport terminals. The SNA was adopted as research methodology. Airport Terminal, Boned, and Chinese Mainland were the keywords for the first period (2003-2008), while the second period (2009-2014) included the keywords such as China, DEA, Airport, and Flight Delay. For the third period (2015-2020), Airport Competitiveness and Aviation Network were also highly connected keywords. This indicates that with the growth of the economy, the research trend of China’s airport terminals has been gradually expanding from infrastructure construction to network development. The results have implications on suggesting the research trend of Chinese airport terminals, and providing insights to the policy makers, academics, and practitioners in neighboring countries including Korea.

This article aims to understand the global and longitudinal trends of research on Panax ginseng. We used bibliometrics to analyze 3974 papers collected from the Web of ScienceTM Core Collection database during 1959--2016. The number of publications showed a steady growth before 2000 and exponentially increased in stage III (2000--2016, about 86% of the papers were published). Research on P. ginseng was conducted in 64 countries, mainly in Asia; in particular, 41% and 28% of the publications were from South Korea and China, respectively. The institutions from South Korea and China had high publication output and close cooperation and provided the majority of financial support. All top 10 authors and four of the top 20 journals in terms of number of publications originated from South Korea. The leading research subjects were pharmacology (39%), plant science (26%), and integrative complementary medicine (19%). The hotspot of P. ginseng research transformed from basic science to application, and multidisciplinary sciences will play a substantial role in the future. This study provides a comprehensive analysis to elucidate the global distribution, collaboration patterns, and research trends in the P. ginseng domain. [ABSTRACT FROM AUTHOR]

The Exchange Market Pressure Index (EMPI) is an indicator of pressure on a currency. Because of the presence of serial correlation, financial time series may not be normally distributed even for large sample sizes. They may have undefined parameters and hence parametric tests of normality may give misleading results. In this paper, we look at the time series of EMPI of eleven countries of the world, put the data to normality check using tests suggested by various scholars. We also apply a test used exclusively for serially correlated data. No one has used this test earlier. In this context, we also compare the power of these statistical tests, which is another novel contribution of this paper. On the basis of these tests the EMPI time series is found to be non-normal. Two tests are found to be the most powerful. The test which is designed exclusively for time series data is found to be powerful only for China and South Korea, the countries which had the lowest EMPI- standard- deviation in the group of all the eleven countries studied in this paper.

With an increasing number of children diagnosed with Autism-Spectrum-Disorder in Canada, this paper focuses on how their mothers, as Asian immigrant women, experience the process of diagnosis and learn to parent their children. By taking two Asian (Korean and Chinese) mothers' critical personal narratives as major data sources, this paper aims to explore the diagnosis process of Autism-Spectrum-Disorder through a sociocultural lens on the intersectionality of (im)migrants and their cultural competence, and argues that their identity (re)construction and learning for parenting take place at the intersectionality of race, gender, class, and disability. This paper highlights possible implications for everyone involved in this 'medical' process, in the context of Canadian or other similar multicultural societies. Asian immigrant mothers usually have to deal with children with Autism-Spectrum-Disorder (ASD) and they have bitter experience of mistreatment tied to race, gender and class. This study reveals how Asian immigrant mothers struggled in their integration to Canadian society as well as their experiences of denial into Canada's medical system. The stories of these two women shed lights on the social and cultural aspects of immigrant mothers' learning strategies, including how they utilize accessible resources and networks for their children's treatment and diagnosis. This paper suggests that policymakers need to consider the social and cultural aspects of diagnosis in immigrant families to better fit their needs and provide them appropriate medical and social support.

The post-World War II experience of conflict and regional cooperation in (Western) Europe and East Asia has been very different. Despite their differences in terms of receptiveness of, and preferences for, regional cooperation, regional cooperation and/or integration still remains one of the most promising avenues for achieving or at least institutionalising peace. Against this backdrop, we aim to assess the scope for EU–Korean collaboration in regional integration, outlining the European and the Korean perspectives on regional integration and conflict resolution, their similarities and differences in this process, and prospects of cooperation amid the intensifying US–China rivalry. We argue in this paper that although confronted with the spectre of global power politics heading for a new Cold War, both the EU and Korea have normatively and practically sought to pursue a policy of 'hedging', and that integration may be a testament to the power of integration in the peaceful transformation of international order than undermining its rationale. The paper thus argues that the future trajectory that regional cooperation for conflict transformation would be bound up by the spectre of power politics by the geostrategic rivalry between the US and China would not necessarily be the only one expected.

Under the background of global energy transformation and structural upgrading, the development of solar photovoltaic industry in various countries has been paid attention to, and solar photovoltaic products occupy an important position in the international trade of renewable energy. The signing of the RCEP agreement can create favorable external conditions for the trade and industrial cooperation of solar photovoltaic products, which has attracted global attention. Therefore, based on the background of RCEP, it is of practical significance to analyze the development and export competitiveness of solar energy products in the agreement countries. This paper uses TOPSIS to establish a comprehensive evaluation index system for the international competitiveness of solar photovoltaic products to study the international competitiveness of solar photovoltaic products in China, Japan, and Korea under the context of RCEP. The study shows that (1) China's international competitiveness in solar photovoltaic products is strong and continues to improve, while Japan is declining and Korea is growing slowly. (2) There are significant differences in the components that lead to international competitiveness among different countries. Based on the above findings, this paper proposes corresponding policy recommendations for the three countries. [ABSTRACT FROM AUTHOR]

This paper examines the history of crossing the Sino-Chosŏn borders in various contexts. The evolution of border crossing can be traced from its origins as a political mission that was part of the diplomatic ritual to its later development as an economic circuit where individuals vied for profits, and finally to its status as a public program that carried significant weight in high-level politics. Throughout its history, border crossing was characterized by its dual nature, encompassing both ritual and mundane, exotic and domestic, national and international elements. It was emblematic of the ongoing interactions between China/Chinese and Korea/Koreans, and the flows of people and goods between them. These individuals and items were re-identified and re-categorized following their crossing of the borders, and the processes of identification and categorization shed light on the political dynamics of both countries.

Purpose: The purpose of this paper is to verify the mediating role of commitment between market-oriented organizational culture and international market performance, and to discuss the moderator effect of national institutional environment on this mediating role. Design/methodology/approach: The research design follows a mixed methodology, combining qualitative and quantitative data collection and analysis. In the first phase, research hypotheses are proposed based on a literature analysis. In the second phase, sample data are collected through interviews and questionnaires sent to domestic contractors in China and South Korea, and a validity analysis of the results is carried out. Correlation and regression analyses are then performed on the valid data to verify hypotheses to prove the existence and influence of mediating effects. Hayes PROCESS Macro is used on the regression results to test the mediating effect of commitment on international project performance and the moderation effect of institutional environment. Findings: The results reveal that the commitment between partners has a mediating effect on the relationship between market culture and international project performance; however, no hierarchy culture is revealed. The mediating effect of commitment is regulated by the institutional environment. Research limitations/implications: Although the reliability and validity of the questionnaire data in this study are in line with research standards, a larger sample size would improve the reliability of the results. Further, the interviewed samples are mainly from China and South Korea; large representative samples from additional countries, such as Japan, should be considered to gain a fuller understanding and more comprehensive results. Originality/value: By emphasizing the differences between the two institutional environments of developing and developed countries in East Asia, a theoretical and empirical basis is provided. International construction enterprises in other countries can apply the findings to improve their international market performance in different institutional environments. The findings also provide an empirical reference that international construction enterprises in China and South Korea may use to adjust their organizational cultures and commitments to improve market performance.

Objective: A scientometric analysis to obtain knowledge mapping of Coptis revealed the current research situation, knowledge base and research hotspots in Coptis research. Methods: Coptis -related documents published from 1987 to 2020 were selected through the Web of Science Core Collection. CiteSpace, VOSviewer and Microsoft Excel were used to construct knowledge maps of the Coptis research field. Results: A total of 367 documents and their references were analyzed. These papers were primarily published in mainland China (214), followed by Japan (57) and South Korea (52), and they each formed respective cooperation networks. The document co-citation analysis suggested that the identification of Coptis Salisb. species, the production of alkaloids, and the mechanisms of action of these alkaloids formed the knowledge bases in this field. A keyword analysis further revealed that the research hotspots were primarily concentrated in three fields of research involving berberine, Coptis chinensis Franch, and Coptis japonica (Thunb) Makino. Oxidative stress, rat plasma (for the determination of plasma alkaloid contents), and Alzheimer's disease are recent research hotspots associated with Coptis. Conclusion: Coptis research was mainly distributed in three countries: China, Japan, and South Korea. Researchers were concerned with the identification of Coptis species, the production of Coptis alkaloids, and the efficacy and pharmacological mechanism of the constituent alkaloids. In addition, the anti-oxidative stress, pharmacokinetics, and Alzheimer's disease treatment of Coptis are new hotspots in this field. This study provides a reference for Coptis researchers.

China has initiated a series of "economic sanctions" against South Korea, affecting Korean pop stars visiting China and Korean investments in China. Sanctions were imposed on South Korea in response to the decision of South Korea to deploy Terminal High Altitude Area Defense (THAAD) in 2016. Furthermore, the Global Daily assembled local population to boycott Korean products and investments in China. However, the Chinese Foreign Ministry has never positively confirmed these activities as economic sanctions to South Korea related to the THAAD installation. In other words, the Chinese government singled a relatively weak message via these sanctions to South Korea. As a result, the THADD implementation continued in South Korea. In the paper, I interpret China's rationale to impost puzzling economic sanctions, which have a weak resolution, to South Korea and Taiwan. As signaling theory argues, economic sanctions with insufficient resolution, which are more likely to fail, is a more provocative foreign policy. By reviewing China's sanctions usage to South Korea and Taiwan, I propose arguments of bureaucratic competition to answer why China launched such sanctions to other countries: those are caused by domestic institutions who are seeking reward from the Communist Party of China. By comparing shifts of leadership between domestic agencies, the paper provides evidence to support the proposed argument. I also include two alternative explanations to strengthen the proposed argument, albeit connecting the paper with other two larger streams of research, which address analyses of China's aggressive foreign policies as well as the domestic politics of economic sanctions.

Passive members are a major part of online political communities, but there is a lack of quantitative research exploring this topic. Furthermore, little is known about how a sense of socialization drives their participation in online political communities. Therefore, this paper tried to depict the drivers of the participation of passive members in online political communities. 591 data were collected through an online survey platform in China and Korea. Then, Mplus8.0 was used to test the related hypotheses, and a multigroup analysis approach has been implemented to quantify the moderating effect of political environment. Results suggest that collective psychological ownership has positively affect sense of community, which then positively affects passive members' sustained participation behavior in the online policy community. By the way, prior behavior observation and perceived political efficacy have a positive effect on socialization. Results also suggest that socialization positively affect sense of community. The findings not only enriched the literature of online political community participation, but also provided important enlightenment for the operation and management of online political community.

Purpose: This paper aims to examine which role governments can play in facilitating the small and medium-sized enterprises (SMEs)' environmental capabilities in a global marketplace. It also investigates whether the extent of the impact of government intervention on firm performance varies depending on country-specific policies. Design/methodology/approach: The authors develop a series of hypotheses that are predicated on the ecological modernization theory and the institutional theory. To test those hypotheses, the authors collected cross-national data reflecting both Korean and Chinese SME practices and then used the structural equation model. In addition, the authors utilized cross-validation techniques for methodological rigor. Findings: A series of hypotheses test results revealed that government intervention had a positive impact on the MNF's environmental innovation capabilities and technological innovation capabilities. In addition, the authors discovered that SMEs' reaction to government intervention had a mediating effect between government intervention and the SME's performance. This discovery verifies the ecological modernization and institutional theories. Originality/value: This is one of the few studies that conducted cross-cultural analyses of two different nations with contrasting government structures (i.e. capitalistic versus socialistic).

Introduction: Endoscopic spine surgery (ESS) is a minimally invasive surgical technique that offers comparable efficacy and safety with less collateral damage compared to conventional surgery. To achieve clinical success, it is imperative to stay abreast of technological advancements, modern surgical instruments and technique, and updated evidence. Purposes: To provide a comprehensive review and updates of ESS including the nomenclature, technical evolution, bibliometric analysis of evidence, recent changes in the spine communities, the prevailing of biportal endoscopy, and the future of endoscopic spine surgery. Methods: We conducted a comprehensive review of the literature on ESS for the mentioned topics from January 1989 to November 2022. Three major electronic databases were searched, including MEDLINE, Scopus, and Embase. Covidence Systematic Review was used to organize the eligible records. Two independent reviewers screened the articles for relevance. Results: In total, 312 articles were finally included for review. We found various use of nomenclatures in the field of ESS publication. To address this issue, we proposed the use of distinct terms to describe the biportal and uniportal techniques, as well as their specific approaches. In the realm of technical advancement, ESS has rapidly evolved from addressing disc herniation and spinal stenosis to encompassing endoscopic fusion, along with technological innovations such as navigation, robotics, and augmented reality. According to bibliometric analysis, China, South Korea, and the USA have accounted for almost three-quarters of total publications. The studies of the biportal endoscopy are becoming increasingly popular in South Korea where the top ten most-cited articles have been published. The biportal endoscopy technique is relatively simple to adopt, as it relies on a more familiar approach, requires less expensive instruments, has a shorter learning curve, and is also well-suited for interbody fusion. The uniportal approach provided the smallest area of soft tissue dissection. While robotics and augmented reality in ESS are not widely embraced, the use of navigation in ESS is expected to become more streamlined, particularly with the emergence of recent electromagnetic-based navigation technologies. Conclusions: In this paper, we provide a comprehensive overview of the evolution of ESS, as well as an updated summary of current trends in the field, including the biportal and uniportal approaches. Additionally, we summarize the nomenclature used in ESS, present a bibliometric analysis of the field, and discuss future directions for the advancement of the field. [ABSTRACT FROM AUTHOR]

This paper evaluates the trade and welfare implications of further East Asian trade integration, through the signing of the China-Japan-Korea FTA, and continued trade tensions between the US and China. Our analysis uses a structural gravity approach to explore the effects of these cooperative and non-cooperative trade policies. Our key findings are: (i) for China, the FTA can compensate for continued trade tensions (ii) in terms of the FTA and for the members involved, reductions in tariffs are expected to lead to larger welfare gains compared to those from lower NTBs (iii) for the members involved, a deeper agreement will be more welfare enhancing. Overall, East Asian integration appears to be a more appealing prospect in light of tensions with the US. [ABSTRACT FROM AUTHOR]

Purpose: This study provides real-world evidence for the relationship between strategic communication from a global/multinational perspective and the effectiveness of corporate message strategies in the context of environment risk communication. Among sustainability issues, particulate matter (PM) air pollution has threatened the health and social wellbeing of citizens in many countries. The purpose of this paper is to apply the message framing and attribution theories in the context of sustainability communication to determine the effects of risk message characteristics on publics' risk responses. Design/methodology/approach: Using a 2 (message frame: gain vs loss) × 2 (attribution type: internal vs external) × 2 (country: China vs South Korea) between-subjects experimental design, the study examines the message framing strategies' on publics' risk responses (i.e. risk perception, risk responsibility attribution held toward another country and sustainable behavioral intention for risk prevention). Findings: Findings include (1) main effects of message characteristics on participants' risk responses; (2) the impact of country difference on participants' differential risk responses and (3) three-way interactions on how risk message framing, risk threats type and country difference jointly affect not only participants' risk perception and risk responsibility attribution but also their sustainable behavioral intention to prevent PM. Research limitations/implications: Although this study used young–adult samples in China and South Korea, the study advances the theory building in strategic environmental risk communication by emphasizing a global/multinational perspective in investigating differences among at-risk publics threatened by large-scale environmental risks. Practical implications: The study's findings provide evidence-based implications such as how government agencies can enhance the environmental risk message strategy so that it induces more desired risk communication outcomes among at-risk publics. Insights from our study offer practical recommendations on which message feature is relatively more impactful in increasing intention for prosocial behavioral changes. Social implications: This study on all measured risk responses reveals important differences between at-risk young publics in China and South Korea and how they respond differently to a shared environmental risk such as PM. The study's findings provide new evidence that media coverage of global environmental issues needs to be studied at the national level, and cross-cultural comparisons are imperative to understand publics' responses to different news strategies. Thus, this study offers implications for practitioners to understand and apply appropriate strategies to publics in a social way across different countries so as to tailor risk communication messaging. Originality/value: This study offers new insights to help connect message framing effects with communication management practice at the multi-national level, providing recommendations for government communication practitioners regarding which PM message features are more likely to be effective in forming proper risk perception and motivate sustainable actions among at-risk publics in different countries.

Bisphenol S (BPS), an organic compound and bisphenol analog, is commonly used as a substitute for bisphenol A. BPS is widely used in epoxy glues, can coatings, and thermal receipt papers; however, its risks have not been fully determined and the probability of its toxicity has been continuously suggested. In this study, we conducted BPS toxicity tests on aquatic plants (acute), cladocerans (acute and chronic), and fish (chronic) to determine its adverse effects, and calculated the toxicity values. Additionally, we conducted an ecological risk assessment of BPS in freshwater ecosystems with toxicity data from previous studies using the species sensitivity distribution method and BPS exposure data from 14 rivers in four countries in Asia (China, Japan, India, and South Korea). The chronic-based risk quotient (RQ) values of BPS in one river in China and two rivers in India were > 1, indicating a high ecological risk of BPS to aquatic organisms. The other four rivers in China showed medium ecological risk (0.1 < RQ < 1) and those in Japan and South Korea showed negligible chronic risk (RQ < 0.1) to aquatic organisms. We also suggest sensitive indicators in the model organism Danio rerio and highlighted the importance of the development of new method of ecological risk assessment. This study could provide new information that will assist in managing BPS and bisphenol analogs in freshwater ecosystems. [ABSTRACT FROM AUTHOR]

Since the establishment of "friendly and cooperative relations' in 1992, relations between South Korea and China have been continuously elevated almost every 5 years. The two countries have achieved great advancements in expanding civil exchanges, bringing economic relations closer, finding common ground in foreign policy and security and elevation of political relations. Despite the honeymoon period that the two countries experienced after they established diplomatic relations, however, conflict is now arising due to differences in opinion and interests in various fields such politics, economy, society, culture, diplomacy, and security. This paper will examine Sino-South Korean relations using the four factor model, which is based on four approaches, starting with economic relations, followed by perception and emotions, diplomacy and security and lastly, these factors" influence on domestic politics. Following this analysis, this paper will argue that despite their continuous but rocky developments, Sino-South Korean relations will sustainably maintain their development. Considering the synergy effect of bilateral relations, two countries are standing on the opportunity to build a New Type of Sino-South Korean relations which would allow for resolution of conflicts and misunderstandings through dialogue and communication.

The purpose of this paper is to investigate the link between culture, history, government policies and the development of economic institutions. Specifically, the paper discusses the impact that history and culture, including the influence of Confucianism, have played in shaping the economic institutions of South Korea and the People's Republic of China. Research results indicate that culture, history and government policies all played a role in shaping the organizational structure of these two East Asian nations. However, China's economic landscape is dominated by small and medium-sized, family-oriented firms, particularly in the rural parts of the country. The South Korean economic landscape, on the other hand, is dominated by large conglomerate firms called Chaebols which are also dominated by one family. [ABSTRACT FROM AUTHOR]

The article discusses the coverage of the "White Paper on International Economy and Trade 2006," in Japan, with emphasis on the Japanese trade issue of international business networks in Asia. The structure of the international division of labor within East Asia, which includes Japan, China, South Korea, was clarified by the paper. In the input-output linkages with the electric machinery sector, an increase in the number of industries with significant linkages with foreign nations was reported.

In this paper, we use a multinomial logit model and identify the important factors in determining the staging categories of Korean tariff concessions in the Korea–China free trade agreement (FTA). We find that most-favored-nation (MFN) tariff rates and whether a product is agricultural or not are the most influential determinants of tariff concessions in the FTA. The results also show that the effects of the determinants are heterogeneous over industries: the influence of the Chinese import share is more pronounced for agricultural products than for manufactured goods, while that of MFN tariffs is less prominent for agricultural products. The latter result implies that quite a few Korean agricultural products are heavily protected in the FTA, despite their relatively low MFN rates. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this paper is to examine individuals' levels of work ethic amongst current and recent university attendees across three countries. This article presents the results of a survey of 537 respondents from the United States of America, Korea and China, thus extending the previous research into work ethic, often conducted from a Western perspective. The comparative study aims to enhance the understanding of cross-cultural and gender differences and similarities whilst probing for the levels of work ethic amongst the respondents. Design/methodology/approach: A comparative research method was adopted because the authors' aim was to probe similarities and differences across three societies. Multiple analysis of variance (ANOVA) and t-tests were utilised to explore gender and country-related differences. Cluster analysis was applied to probe for segments highly similar to each other in the levels of work ethic of the respondents. Findings: The results confirm the hypothesised differences between countries as well as across gender groups, with American females having the highest levels of work ethic, closely followed by Chinese males and females. Three distinct segments – low, medium and high levels of work ethic – were found in all three countries, indicating that there are individuals in each of the societies who could benefit from strategies for increasing the individuals' levels of work ethic. Originality/value: Novel gender comparisons of the three country groups revealed American females as having the highest levels of work ethic and Korean females the lowest, whilst the identification of clusters of low, medium and high levels of work ethic provides evidence of the need to increase levels of work ethic to enhance productivity, regardless of the country of origin.

This paper investigates the impact of the monetary policies in 3 countries (the Republic of Korea, China and the United States) on the Korean stock markets (e.g., KOSPI), using a structural Vector Autoregression. We find that a positive shock in Money Supply (M2) in all 3 countries is positive to the Korean stock markets but the degree of the response differs from one another. Surprisingly, the response of the KOSPI was largest to China's M2, reflecting that China is Korea's largest trading partner. From the responses of Korea's industrial production and CPI, we speculate that a possibility of liquidity trap was not ruled out in some periods. We also find that the KOSPI responded negatively to a positive shock in Korea's policy rate while it rarely responded to the shocks in the China's policy rate and the US federal fund rate. We consider that China's policy rate did not affect Korea's economic activities as it was not a main monetary policy tool. We also consider that Korea's determination of policy rate was not fully free from the US monetary policy and thus any shock in the US federal fund rate was substantially mitigated in the KOSPI.

This paper examines whether second language (L2)-English learners whose native languages (L1; Korean and Mandarin) lack obligatory plural marking transfer the properties of plural marking from their L1s, and whether transfer is manifested both offline (in a grammaticality judgment task) and online (in a self-paced reading task). The online task tests the predictions of the morphological congruency hypothesis (Jiang 2007), according to which L2 learners have particular difficulty automatically activating the meaning of L2 morphemes that are incongruent with their L1. Experiment 1 tests L2 learners' sensitivity to errors of –s oversuppliance with mass nouns, while Experiment 2 tests their sensitivity to errors of –s omission with count nouns. The findings show that (a) L2 learners detect errors with nonatomic mass nouns (sunlights) but not atomic ones (furnitures), both offline and online; and (b) L1-Korean L2-English learners are more successful than L1-Mandarin L2-English learners in detecting missing –s with definite plurals (these boat), while the two groups behave similarly with indefinite plurals (many boat). Given that definite plurals require plural marking in Korean but not in Mandarin, the second finding is consistent with L1-transfer. Overall, the findings show that learners are able to overcome morphological incongruency and acquire novel uses of L2 morphemes. [ABSTRACT FROM AUTHOR]

This paper explores the diverse ways Chinese policymakers view the foreign policy process in China. Two approaches characterize conventional accounts of the foreign policy decision-making process. One of these, based on Graham Allison's rational, organizational, and bureaucratic politics models, focuses on intragovernmental aspects of foreign policy decision-making processes, while the other highlights extra-governmental domestic and foreign factors. However, these approaches have neglected the question of who leads foreign policy and how state, society, and grassroots interact through coalition. We interviewed Chinese scholars and foreign policy experts using Q statements to explore China's foreign policy response to South Korea's deployment of THAAD. Our findings offer new theoretical insights into China's foreign policy process by identifying state-driven, grassroots-based, and state-society coalition models. [ABSTRACT FROM AUTHOR]

The current environment is highly dynamic and undergoing continuous change, and the recent outbreak of the COVID-19 pandemic has shown how firms and governments need to act promptly to face unexpected threats. In this regard, location-based applications have been implemented successfully in China and South Korea, but in some Western countries, serious privacy issues have been raised. With these premises in mind, this paper has the aim of examining the factors that motivate or discourage users to adopt mobile applications able to trace location. The proposed model is based on the combination of the Protection Motivation Theory, the Theory of Planned Behavior, and the Technology Acceptance Model. A variance-based Structural Equations Modeling approach has been used to test the conceptual model using Partial Least Squares (PLS). The findings show that perceived usefulness positively influences attitude. In addition, subjective norms and self-efficacy were found to be the key drivers of the intention to adopt location-based applications, whilst perceived severity emerged as an important barrier. Finally, this study provides empirical evidence for the positive and significant relationship between the intention to use this type of apps and actual behavior. Academic and managerial implications are drawn and future research directions are suggested. [ABSTRACT FROM AUTHOR]

Taoism and Confucianism both exited simultaneously as philosophies of living in dynastic China. Although there has been an increasing popularity in scientometric studies, religion and health (R&H) literature lacks a holistic evaluation investigating articles relevant to Taoism and Confucianism. All publications produced in Taoism and Confucianism literature and indexed in Web of Science (WoS) databases between 1975 and 2018 were included in this study. Database search on health and Taoism literature retrieved 199 documents from WoS databases. Main research areas were Psychology, Religion and Behavioral Sciences (24.121, 21.608 and 20.603, respectively). The USA ranked first with 38 papers followed China, Taiwan and the UK (n = 35, 20 and 6 documents, respectively). Hong Kong Polytechnic University from China was the most contributor institution in health and Taoism literature. A total of 448 documents were published in health and Confucianism literature between 1975 and 2018, and original articles covered 93.08% of all literature. China was leading country with 126 articles followed by the USA, South Korea and Taiwan (n = 97, 35 and 35 items, respectively). The most productive institutions were City University of Hong Kong (China), Karolinska Institute (Sweden) and University of Hong Kong (China). Researchers from developing and least developed countries should be encouraged to carry out novel scientometric studies in R&H literature. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this narrative is to share insights on the little-known two-by-two evangelical sect, specifically its use of English teaching in South Korea and China as a missionary tool of conversion. Design/methodology/approach: This narrative is written in memoir-style, with sections that analyze the author's experiences. The analysis looks at the two-by-two sect through the lens of Gee's Theory of Discourse. Findings: Based on the author's experiences as an insider for 35 years in the two-by-two evangelical sect, four of those in China and S. Korea, she discusses the use of English teaching as a missionary tool of conversion. The paper questions the ethicality of this practice. Practical implications: The author suggests that global English teachers should carefully examine their own religiosity to make sure they are not ethically compromising opportunities for their students in an effort to create converts. Originality/value: This paper sheds light on the global nature of the two-by-two sect, a religion that has very little written about it in the scholarly realm. [ABSTRACT FROM AUTHOR]

Featured Application: Our research not only provides a method for estimating evapotranspiration, but also provides the possibility for additional remote sensing models to appear on a "minute" or even "second" time scale. Using remote sensing to estimate evapotranspiration minute frequency is the basis for accurately calculating hourly and daily evapotranspiration from the regional scale. However, from the existing research, it is difficult to use remote sensing data to estimate evapotranspiration minute frequency. This paper uses GF-4 and moderate-resolution imaging spectroradiometer (MODIS) data in conjunction with the Surface Energy Balance Algorithm for Land (SEBAL) model to estimate ET at a 3-min time interval in part of China and South Korea, and compares those simulation results with that from field measured data. According to the spatial distribution of ET derived from GF-4 and MODIS, the texture of ET derived from GF-4 is more obvious than that of MODIS, and GF-4 is able to express the variability of the spatial distribution of ET. Meanwhile, according to the value of ET derived from both GF-4 and MODIS, results from these two satellites have significant linear correlation, and ET derived from GF-4 is higher than that from MODIS. Since the temporal resolution of GF-4 is 3 min, the land surface ET at a 3-min time interval could be obtained by utilizing all available meteorological and remote sensing data, which avoids error associated with extrapolating instantaneously from a single image.

This paper responds to the call for more focus on how micro-level processes of identity regulation are shaped by, and constitutive of, wider societal institutions. We provide a case study of identity regulation in a Chinese multinational and show how senior managers in the firm draw on distinctive national and organizational contexts in China to construct, reinforce and reproduce a particular set of identities for employees. These identities draw upon discourses in the wider Chinese context which reflect the struggle of China to become a major industrial power after a century of humiliation by the West and the need for employees to provide this extra effort in the face of the existential challenges faced by the company and by the country. We demonstrate how managers create specific HR mechanisms that intertwine these discourses with the identities of employees and with the identity of the organization. This paper contributes to a better understanding of how micro-processes of identity work and mid-level processes of identity regulation and firm strategy are linked to macro-level institutional structures. Based on the framework provided, the paper discusses how far similar identity regulation mechanisms could be adopted elsewhere where similar macro-level discourses might be available, first in other Chinese MNCs, second, in other East Asian countries such as South Korea, third, more widely in emergent economies where MNCs are embedded in state-driven forms of capitalism, and finally in developed economies where populist nationalism is becoming increasingly influential. In this way, studies of identity regulation can bring organization studies into greater dialogue with other social sciences concerned with wider institutional change and continuity [ABSTRACT FROM AUTHOR]

Previous studies of East Asian welfare regimes focus on similarities between social security schemes. In contrast, this paper explores cross-national variations in public–private pension mixes in six welfare states: China, Hong Kong, Japan, Singapore, South Korea and Taiwan. Our research echoes the pension policy analysis of international organisations but takes a step forward with emphasis on the historical and institutional characteristics of the respective pension systems. The analysis identifies three institutional patterns. First, the statist pension system (Taiwan and China) primarily relies on public pensions to provide old-age security, with private pensions playing a rather minor role. Second, in the dualist pension system (Japan and Korea) both public and private pensions work in parallel to ensure retirement income, though a clear security gap exists between workers in the formal and informal economies. Finally, the individualist pension system (Hong Kong and Singapore) is characterised by genuine fully funded individual accounts, emphasising citizens' own responsibilities for ensuring old-age security. These three types of pension systems demonstrate distinct institutional characteristics and policy outcomes, illustrated by the juxtaposition of their institutional structures as well as by the comparison of key indicators collected from government reports and Organisation for Economic Co-operation and Development statistics. The paper concludes with a theoretical reflection of East Asian pension policies and a diagnosis of the distinct challenges confronted by each of the various pension patterns. [ABSTRACT FROM AUTHOR]

This paper applies the Markov-switching model to analyse the transition probabilities and generalized method of moments (GMM) with Newey–West heteroscedasticity and autocorrelation consistent covariance estimators (HAC) to examine the continuity of monetary policies in different countries when the U.S. and China change their monetary policies. Our results indicate that the euro area's monetary authority continues to increase/decrease their money supply to stimulate/depress the economy. In Japan, long-term economic recession motivated the Japanese government to maintain a loose money supply. The continuity of Korea's monetary policy in expansionary states lasts up to 5.1 years. Besides, the outcomes show the implementation of U.S. quantitative easing (QE), overnight reverse repurchase agreement (RRP), and Chinese RRP policies have significant spillover effects on other nations. Particularly, the effects on the euro area are the largest. Furthermore, although the monetary policies of China and the euro area seem to move in opposite directions, they are interdependent.

The politics of international finance for coal power plants have intensified since the 2015 Paris climate agreement was negotiated. Over the past few years, Japan and South Korea have signaled their intent not to fund new coal projects overseas, leaving China and its Belt and Road Initiative as the 'financier of last resort.' In September 2021, China too announced its intent to stop providing finance for overseas coal projects. What accounts for their decision to cease financing overseas coal projects despite prominent differences in political systems, degree of internationalization of their financial systems, and economic size? Drawing on datasets of coal projects and financing supplemented by case material and interviews, this paper explores the dynamics of coal export finance and how the combination of international reputational pressures and declining demand for coal finance diminished the domestic support for incumbent coal exporters in all three countries.

Artificial intelligence (AI) is being used in our daily lives, in all situations and in particular those concerning service systems. However, there is an absence of the ability of the conceptual structure, thematic structure, intellectual structure, and research trends of AI and disruptive technologies in service systems. The main purpose of this study was to carry out a bibliometric analysis of the scientific production of AI and disruptive technologies in service systems based on Elsevier's Scopus database. To do so, keywords were chosen and then data outputs such as the number of published documents, top authors and citations, top journals, countries, and affiliations with the highest number of productions, and network analysis using R-based "biblioshiny" software. The main results showed the growing interest in the subject in the last five years, pointed out current themes and research trends, and revealed the intellectual structure of the field, namely the importance of smart services, cloud computing, and smart sustainable cities. The number of articles for this study reached 1,323, the growth rate has increased in the last five years and the main sources have been reported. China, South Korea and the USA were the leading countries on the subject, and the top 10 authors of influence showed. The word cloud and word growth were presented, as well as the co-citation clusters and co-occurrence network revealed important aspects, and finally the thematic map and the thematic evolution of the subject showed the important concepts. It is hoped that this research will supply future directions for researchers in the area while highlighting the potential of quantitative methods. [ABSTRACT FROM AUTHOR]

We estimate the degree and scope of PM2.5-induced negative price shock in Korea's local housing markets, taking a two-stage hedonic approach. For the analysis, Korea's local PM2.5 levels are treated as endogenous and are instrumented with regional air pollutants from China. We find that a unit µg/m3 PM2.5 level increase in a Korean city is associated with a 3.7% decline in local residential property value. Long-range transboundary pollution has significant effects on Korea's local PM2.5 levels with an elasticity of 0.05. These results enrich the sparse hedonic literature on local air-quality valuation in connection to long-range transboundary pollution in East Asia. The advanced methodological features presented in our two-staged identification strategy with a novel instrument is another contribution of this paper. [ABSTRACT FROM AUTHOR]
