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.

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]

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]

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.

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]

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.

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.

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.

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]

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]

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]

The aim of this study is to identify the most prolific countries in the field of special education and to discuss the widespread impact of their papers by taking into account the country's h-index. Through a bibliometric analysis, the data were collected in the Web of Science Core Collection category "Education, Special" in the Social Science Citation Index during 2011-2020. The 25 most prolific countries in the field of special education were determined in terms of paper productivity, and it was seen that the leading country was undisputedly the USA (54.42%). Meanwhile, a strong positive correlation was found between the h-index and the number of papers published by the countries (r=0.864). On the other hand, when the ranking in terms of the number of papers was reconfigured by the h-index, it was relatively changed. The possible reasons for this change for the countries with the most changing rankings were discussed by considering some definitive criteria such as the journal quartiles, the percentage of international and domestic, and the percentage of open access papers. This study reports a positive correlation between the quality and quantity in the field of special education for the publications of countries. It has been shown that where the positive correlation deviates, then especially, the journal quartiles, the percentage of international collaboration and the percentage of open access papers have a significant effect. The bibliometric findings may be useful to enrich the discussion about the widespread impact of papers and debate whether the use of h-index is acceptable for cross-national comparisons.

In the past decade, Korea and Japan have increasingly exhibited different strategic priorities in trade in face of China's rising global economic prowess and worsening USChina trade conflict. Japan's trade policy decisions have worked to reinforce its economic and security ties with the US as a means to counter China. Japan has used both bilateral and multilateral means to secure its ties with the US against China. In contrast, Korea's trade policy positions have been one of 'strategic ambiguity'. Korea has been more conciliatory towards China, reluctant to take actions that would counter China's interest. Korea has mainly resorted to bilateral channels to maintain favorable relations with both China and the US. Korea's reluctance to clearly ally with the US against China has been observed across different administrations with opposing political orientations. This paper examines Korea and Japan's diverging strategic priorities in trade through the 2017 World Trade Organization Ministerial Conference; the 2017 US imposition of Section 232 on steel; the Comprehensive and Progressive Agreement for Trans-Pacific Partnership, the Korea-US FTA renegotiation and the Korea-China FTA Phase Two Negotiation; and the 2019 Japan-US Trade Agreement.

Qiu Jun of Ming China, with the aim of "rendering the Zhuzi jiali both accessible and practicable for ordinary folks," compiled the Jiali yijie. Among the annotations of Jiali in the Ming dynasty, Jiali yijie gained the widest popularity and greatest influence, and was regarded as a new classic, on par with the Jiali itself. In the 16th century, Jiali yijie was also introduced to Joseon Korea, where it was regarded as "an important supplement to the Zhuzi jiali" by Korean scholars, attaining a high level of popularity. This paper draws on 23 versions of the Jiali yijie from the Ming dynasty and 33 from the Qing. Historically, the Jiali yijie was introduced to the Joseon dynasty from China by Kim Anguk in 1518. Through the comparison of these four Joseon print versions and their Chinese counterparts, we are led to the conclusion that it was the Yingtian prefecture's print, dated the twelfth year of the Zhengde Era, that Kim Anguk brought back to Joseon from Ming China.

Medical electrical impedance tomography (EIT) reconstruction algorithms are approximately forty years old and are now being used to treat patients. At the same time, many advanced concepts are still active research areas, and literature regarding EIT algorithms has been presented in different professional journals and scientific conferences. Bibliometrics analysis method is used to assess the 30 years of scientific output and activity regarding EIT algorithm research from a global perspective, covering global publications, cooperation between countries, and clustering of keywords. 2467 research articles, reviews, letters, and proceeding papers published from 1987 to 2021 in English on EIT reconstruction algorithm were analyzed. Literature statistics show that the worldwide growth trend is rising, and global geographic distribution of publications in this field indicates that USA, South Korea, and China ranked as the top three prolific contributors in terms of EIT algorithm. "inverse problem" "regularization""electrode models" were research focus. Overall, EIT algorithms bibliometric research provides the current hotspots and future directions of algorithm research.

The various possibilities that social media offers to language learners and teachers have long been recognized by researchers within the field of language instruction, and many studies have been carried out in an attempt to address and unpack its potential contributions. This paper aims to review such research on the use of mainstream social media in language teaching and learning published in "Computer Assisted Language Learning," a top tier (i.e., Q1) journal indexed in major citation index systems (e.g., Arts & Humanities Citation Index, the Social Sciences Citation Index and Scopus), between the years 2016-2020 inclusive. For the purposes of the study, a total of 23 articles that meet the selection criteria is reviewed and presented in five sections. The first section deals with the majority of the articles, which are found to be on the use of social networking in language teaching and learning. In the following sections, studies on the use of videoconferencing, wikis, blogging and forums are discussed. Collectively, the studies reviewed in this paper outline a critical role for the use of social media in language instruction and the study aims to provide valuable insights for researchers, teachers and learners.

In recent years, several studies pointed out that anthropogenic emission sources in China which significantly contribute to the PM2.5 mass burden was an important cause of particulate pollution in South Korea. However, most studies generally focused upon a single pollution event. It is rare to see comprehensive research that captures those features prone to interannual variations concerning the transboundary pollutant contribution in South Korea using a unified method. In this paper, we establish the emission inventories covering East Asia in 2010, 2015, and 2017, and then conduct the source apportionment by applying a coupled regional air quality model called the Integrated Source Apportionment Module (ISAM). Comparison of simulated and observed PM2.5 mass concentration at 165 CNEMC (China National Environmental Monitoring Center) sites suggests that the PM2.5 concentrations are well represented by the modeling system. The model is used to quantitatively investigate the contribution from emission sources in China to PM2.5 concentrations over South Korea and those features found to be prone to interannual variations are then discussed. The results show that the average annual contribution of PM2.5 has dropped significantly from 28.0% in 2010 to 15.7% in 2017, which strongly suggests that China has achieved remarkable results in the treatment of atmospheric particulates.

This paper employs the threshold cointegration methodology to assess the long- and short-run dynamics of asymmetric adjustment between economic policy uncertainty (EPU) of China-India, China-Japan, China-Korea, India-Japan, India-Korea, and Japan-Korea pairs using monthly EPU data ranging from January 1997 to April 2020. The relationship between the EPU pairs is examined in terms of Engle-Granger and threshold cointegrations. The findings provide evidence of long-run threshold cointegration and that the adjustments towards the long-run equilibrium position are asymmetric in the short run for the China-India and India-Japan EPU pairs in M-TAR specification with nonzero threshold values. Also, the results suggest a unidirectional causal relationship between China-India, China-Japan, and India-Korea EPU pairs in the long and short run using the spectral frequency domain causality approach. However, a bidirectional causal relationship between China-Korea, India-Japan, and Japan-Korea pairs exists in the long and short run. Therefore, the findings provide some clues to economic policymakers within the Asian subregion for possible policy uncertainty synergies and spillovers among the Asian countries.

Background The rising incidence of thyroid cancer (TC) has generated growing concern globally; yet there are no studies examining whether this incidence was followed by a rise in related mortality. We aimed to comprehensively quantify current trends and future projections of TC incidence and mortality, and to explore the association between the TC burden and socioeconomic inequality in different income strata. Methods We obtained incidence and mortality data on TC and population from the 2019 Global Burden of Disease (GBD) study and the United Nations' World Population Prospects 2022. We applied an age-period-cohort (APC) model to estimate the overall annual percentage change (net drift) and age, period, and cohort effects from 1990 to 2019, and also constructed a Bayesian APC model to predict the TC burden through 2030. Results Over a third of global TC cases belonged to the high-income group. From 1990 to 2019, net drifts of TC incidence were >0 in all income groups, while a modest reduction (net drift <0) in mortality was observed in most income groups, except for the lower-middle-income group. Unfavourable age, period, and cohort effects were most notable in Vietnam, China, and Korea. The age-standardised incidence rate (ASIR) is predicted to increase whereas the age-standardized mortality rate (ASMR) is expected to decrease globally between 2020 and 2030, with geographic heterogeneity being detected across income groups. We observed a positive correlation between ASIR and universal health coverage index and health worker density, but a negative one between ASMR and the two indicators, primarily in upper-middle-income and high-income countries. Conclusions Opposite patterns in incidence and mortality of TC raise concerns about overdiagnosis, particularly in upper-middle-income and high-income countries. Discrepancies in the distribution of health service accessibility, including diagnostic techniques and therapeutic care, should be addressed by narrowing health inequalities in the TC burden across countries.

• This study applied a logistic growth model with parameters estimated by a non-linear least squares (NLS) method to daily new COVID-19 cases. • The model fitted time-series data exceedingly well for the whole of China, eleven selected Chinese provinces and municipalities, South Korea and Iran. • This study provided key estimates and a 95% confidence interval for parameters K , r, and P 0. • This study found that the growth rates of outbreaks differed between provinces in China and between South Korea and Iran. • As of March 13, 2020, this study's model suggested that countries such as the U.S.A., France, Italy, and Spain were still in the early stages of outbreaks. As the coronavirus disease 2019 (COVID-19) pandemic continues to proliferate globally, this paper shares the findings of modelling the outbreak in China at both provincial and national levels. This paper examines the applicability of the logistic growth model, with implications for the study of the COVID-19 pandemic and other infectious diseases. An NLS (Non-Linear Least Squares) method was employed to estimate the parameters of a differentiated logistic growth function using new daily COVID-19 cases in multiple regions in China and in other selected countries. The estimation was based upon training data from January 20, 2020 to March 13, 2020. A restriction test was subsequently implemented to examine whether a designated parameter was identical among regions or countries, and the diagnosis of residuals was also conducted. The model's goodness of fit was checked using testing data from March 14, 2020 to April 18, 2020. The model presented in this paper fitted time-series data exceedingly well for the whole of China, its eleven selected provinces and municipalities, and two other countries - South Korea and Iran - and provided estimates of key parameters. This study rejected the null hypothesis that the growth rates of outbreaks were the same among ten selected non-Hubei provinces in China, as well as between South Korea and Iran. The study found that the model did not provide reliable estimates for countries that were in the early stages of outbreaks. Furthermore, this study concured that the R 2 values might vary and mislead when compared between different portions of the same non-linear curve. In addition, the study identified the existence of heteroskedasticity and positive serial correlation within residuals in some provinces and countries. The findings suggest that there is potential for this model to contribute to better public health policy in combatting COVID-19. The model does so by providing a simple logistic framework for retrospectively analyzing outbreaks in regions that have already experienced a maximal proliferation in cases. Based upon statistical findings, this study also outlines certain challenges in modelling and their implications for the results. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this paper is to investigate the legal issues of simultaneous Internet transmission of broadcasting programs of the Open University of Japan (OUJ) and to take legal measures to promote the mutual utilization of open university courses in Japan, the UK, China and Korea. Design/methodology/approach: The author examines the legal relationship regarding Internet simultaneous distribution of broadcast courses at the OUJ. The author then considers the legal relationship between the UK, China and South Korea regarding the simultaneous transmission of broadcast courses over the internet. Based on that consideration, this paper clarifies legal measures to promote its utilization. Findings: Internet transmission of broadcasting courses will be webcasting. Arguably, it can be assumed to be streaming and on-demand, albeit controversial. Webcasting will be publicly transmitted, but there is only an on-demand provision for Internet transmission. As webcasting is streaming and on-demand, it involves reproduction of broadcasting courses. Therefore, webcasting needs to provide streaming provision for public transmission rights and associate them with reproduction right. Originality/value: The originality of this paper lies in clarifying the legal response of the object, subject and rights of webcasting from the perspective of the OUJ, in order to dispel legal problems that may arise in the future against this unexplored phenomenon. Additionally, this paper is valuable in that it presents legal consistency from the point of view of the comparative laws of Japan, the UK, China and South Korea, based on an examination of the legal response in Japan.

Reverse brain drain (RBD) is a fertile area to examine in the inter-countries movement of professionals. The basic idea of RBD is that the professionals who migrated to the industrialized nations represent potential human resources for the socioeconomic development of their home countries. It is argued that every 'brain drain' is a potential 'brain gain' for a country. However, there is inconclusive evidence on the best practices of RBD that may become lessons for any country to adopt in tapping the valuable experiences of the intellectual elites. Using 'human capital theory' and 'diffusion of innovation theory', this conceptual paper specifically aims i) to illustrate evidence of the best practices of RBD in selected Asian developing countries of South Korea, Taiwan, China, and India that have commended track records in dealing with RBD; and ii) to suggest strategies for Malaysia, which is a beginner in developing the RBD programs, to adopt the best practices as experienced by the selected countries.

It has been observed that since the Early Qing Dynasty, the eastward spread of Western classics has been in decline; this article aims to looks at how Protestant missionaries helped to revive it in the late nineteenth and early twentieth centuries. First, this study examines the circumstances that Protestant missionaries faced upon arriving in China and describes the challenges, opportunities, and issues they encountered when attempting to spread Western classics as part of their missionary effort. Second, this article reveals the strategies Protestant missionaries employed to revive the Western classics, with a focus on the utilization of the translated literature, press, and academic institutions. Third, this article explores the ways the spread of Western classics by the missionaries of the late nineteenth and early twentieth century outshone the achievements of their predecessors of the late sixteenth and seventeenth centuries. Unlike the missions through secular knowledge in China, the spread of Protestantism in Korea took place in a more direct manner. This comparative study in the last section highlights the importance of each country's endowment in terms of the method and effectiveness of missionary efforts. [ABSTRACT FROM AUTHOR]

In this article, the authors discuss what public administrative theory says about promoting optimal levels of performance and accountability and what the papers in this issue say about this issue with regard to public administration in the People's Republic of China, the United States, and the Republic of Korea. The papers in this issue explore performance and accountability at various levels of government. The article notes that the three countries have different governments at different levels of experience, they all struggle with similar public administration problems.

Previous research shows that transnational entrepreneurs move between home and host societies, taking advantage of new markets, currency differentials, and transnational resources. This paper problematizes current theories that stress the importance of human capital in transnational entrepreneurship, by highlighting the powerful role that cultural skills can play in the mobilization of resources. Using ethnographic, interview, and survey data from transnational firms in Beijing's Korean enclave, the paper compares the experiences of South Korean and Korean Chinese entrepreneurs in Beijing, and demonstrates how Korean Chinese, who have lower levels of human capital and material resources, are able to achieve upward mobility by using their positions as cultural middlemen whereas the South Korean entrepreneurs, despite better access to seed money, education, and entrepreneurial experience, are crippled by their limited cultural knowledge.

This article maps the scientific production and the contents associated with the sustainable development goals and their integration with universities during the past 21 years. Although many of the topics related to sustainable development goals (SDGs) have been addressed in different studies for decades, it is since 2015 onwards that they gained greater prominence due to the inclusion of higher education as an important actor in the fulfillment of the 2030 agenda and the United Nations SDGs. For the purpose of this paper, a bibliometric analysis of 871 papers, 535 documents in Scopus, and 336 in Web of Science (WoS) from 1998 to 2019 was performed, and the Bibliometrix analysis tool was used. The objective of this mapping is to answer the following research question: Is the integration of the Sustainable Development Goals and Universities a field of study? An analysis of the network of collaborators and trend topics in Scopus and WoS allows us to identify the concurrence and relationships of some keywords, such as sustainable development, sustainability and planning, and some background words, such as humans and global health. In another analysis, the word "higher education" is related to change. This article suggests that the integration of the Sustainable Development Goals in Universities is becoming a field of study under exploration, with a peak of production in 2016 and that has remained stable in the last three years, but thanks to the leading role assigned to Universities, intellectual production should increase in the following years.

The spectacular economic success of the Newly Industrialising Countries (NICS) of Asia since the 1960s, has led to the quest to identify other less developed countries which may be just about to become the next NICS of Asia. This paper examines the arguments for and against the view that there is a "second tier" of less developed countries which are about to join the ranks of the Asian NICS. While Malaysia and Thailand are generally thought to be the most likely candidates, this paper argues that one hitherto unrecognised contender. China, is likely to join these countries in achieving NIC status. This paper examines the question of whether there are likely to be more Newly Industrializing Countries (NICS) emerging over time, following in the footsteps of the original four in Asia (Hong Kong, Singapore, South Korea and Taiwan). While some writers suggest that several developing countries are about to achieve NIC status in the near future, others argue that world trading conditions have deteriorated to such an extent as to make this very unlikely.

In this study, the WRF-Chem v4.4 model was utilized to evaluate the sensitivity of O 3 simulations with three bottom-up emission inventories (EDGAR-HTAP v2 and v3 and KORUS v5) using surface and aircraft data in East Asia during the Korea-United States Air Quality (KORUS-AQ) campaign period in 2016. All emission inventories were found to reproduce the diurnal variations of O 3 and its main precursor NO 2 as compared to the surface monitor data. However, the spatial distributions of the daily maximum 8 h average (MDA8) O 3 in the model do not completely align with the observations. The model MDA8 O 3 had a negative (positive) bias north (south) of 30° N over China. All simulations underestimated the observed CO by 50 %–60 % over China and South Korea. In the Seoul Metropolitan Area (SMA), EDGAR-HTAP v2 and v3 and KORUS v5 simulated the vertical shapes and diurnal patterns of O 3 and other precursors effectively, but the model underestimated the observed O 3 , CO, and HCHO concentrations. Notably, the model aromatic volatile organic compounds (VOCs) were significantly underestimated with the three bottom-up emission inventories, although the KORUS v5 shows improvements. The model isoprene estimations had a positive bias relative to the observations, suggesting that the Model of Emissions of Gases and Aerosols from Nature (MEGAN) version 2.04 overestimated isoprene emissions. Additional model simulations were conducted by doubling CO and VOC emissions over China and South Korea to investigate the causes of the model O 3 biases and the effects of the long-range transport on the O 3 over South Korea. The doubled CO and VOC emission simulations improved the model O 3 simulations for the local-emission-dominant case but led to the model O 3 overestimations for the transport-dominant case, which emphasizes the need for accurate representations of the local VOC emissions over South Korea.

Background: As chromatographic techniques have advanced, many articles that analyze the constituting compounds of medicinal materials have been published in relation to Northeast Asian traditional medicine, including traditional Chinese medicine (TCM). TM-MC was launched in 2015, providing information about the chemical compounds in medicinal materials from chromatographic articles in PubMed. Since 2015, through continuous curation efforts, we have now released TM-MC 2.0 with significant improvements to the quantity and quality of the data (https://tm-mc.kr). Description: TM-MC 2.0 contains 635 medicinal materials, 34,107 chemical compounds (21,306 identified and de-duplicated), 13,992 targets, 27,997 diseases, and 5,075 prescriptions (2,393 de-duplicated by name). The database provides the largest number of identified compounds for medicinal materials listed in the pharmacopoeia compared to all TCM databases. In particular, marker compounds of medicinal materials and many newly discovered compounds were added through the manual curation of recent chromatographic articles. Conclusion: TM-MC 2.0 provides the largest collection of information about the chemical compounds of the medicinal materials listed in the Korean, Chinese, and Japanese pharmacopoeias. Our database can be utilized for network pharmacology in traditional medicine and for the compound screening of medicinal materials for modern drug discovery. [ABSTRACT FROM AUTHOR]

Transboundary fine dust has been a leading cause of dispute between China and Korea since the mid‐2010s. This study observes that transboundary fine dust is not purely an environmental issue, but rather mixed with political and diplomatic challenges. Despite the emerging bilateral and multilateral efforts to tackle this issue, this research sheds light on how political and diplomatic factors have undermined the outcomes of environmental negotiations between China and Korea. We highlight three dimensions of policy‐based studies: scientific joint research on source‐receptor relationships, interstate environmental negotiations, and multilateral environmental institutions in Northeast Asia. This study argues that transboundary fine dust cooperation has been extensively entangled with national political interests and proceeded via diplomatic channels, leading to the current absence of binding agreements and policy commitments. Therefore, a steady process of de‐linking environmental cooperation and diplomatic fluctuations would be the best direction to proceed in a long‐term perspective. [ABSTRACT FROM AUTHOR]
