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.

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.

Epimedii Herba (EH) is an herbal medicine originating from several plants of the genus Epimedium. It is a major therapeutic option for kidney yang deficiency syndrome, which is closely related to androgen hormones and also has been used to treat hemiplegia following a stroke in traditional medicine of Korea and PR China. To date, many clinical and basic researches of EH have shown the activities on functional recovery from brain diseases. Recently, neuroplasticity, which is the spontaneous reaction of the brain in response to diseases, has been shown to accelerate functional recovery. In addition, androgen hormones including testosterone are known to be the representative of neuroplasticity factors in the brain recovery processes. In this review, we described the neuro-pharmacological activities of EH, focusing on neuroplasticity. Thirty-three kinds of papers from MEDLINE/PubMed, EMBASE, and CNKI were identified and analyzed. We categorized the results into five types based on neuroplasticity mechanisms and presented the definition of each category and briefly described the results of these papers. Altogether, we can suggest that neuroplasticity is a novel viewpoint for guiding future brain research of EH and provide the evidence for the development of new clinical applications using EH in the treatment of brain diseases.

Aims: This paper presents updated prevalence estimates of awareness, ever‐use, and current use of nicotine vaping products (NVPs) from 14 International Tobacco Control Policy Evaluation Project (ITC Project) countries that have varying regulations governing NVP sales and marketing. Design, Setting, Participants and Measurements: A cross‐sectional analysis of adult (≥ 18 years) current smokers and ex‐smokers from 14 countries participating in the ITC Project. Data from the most recent survey questionnaire for each country were included, which spanned the period 2013–17. Countries were categorized into four groups based on regulations governing NVP sales and marketing (allowable or not), and level of enforcement (strict or weak where NVPs are not permitted to be sold): (1) most restrictive policies (MRPs), not legal to be sold or marketed with strict enforcement: Australia, Brazil, Uruguay; (2) restrictive policies (RPs), not approved for sale or marketing with weak enforcement: Canada, Malaysia, Mexico, New Zealand; (3) less restrictive policies (LRPs), legal to be sold and marketed with regulations: England, the Netherlands, Republic of Korea, United States; and (4) no regulatory policies (NRPs), Bangladesh, China, Zambia. Countries were also grouped by World Bank Income Classifications. Country‐specific weighted logistic regression models estimated adjusted NVP prevalence estimates for: awareness, ever/current use, and frequency of use (daily versus non‐daily). Findings NVP awareness and use were lowest in NRP countries. Generally, ever‐ and current use of NVPs were lower in MRP countries (ever‐use = 7.1–48.9%; current use = 0.3–3.5%) relative to LRP countries (ever‐use = 38.9–66.6%; current use = 5.5–17.2%) and RP countries (ever‐use = 10.0–62.4%; current use = 1.4–15.5%). NVP use was highest among high‐income countries, followed by upper–middle‐income countries, and then by lower–middle‐income countries. Conclusions: With a few exceptions, awareness and use of nicotine vaping products varied by the strength of national regulations governing nicotine vaping product sales/marketing, and by country income. In countries with no regulatory policies, use rates were very low, suggesting that there was little availability, marketing and/or interest in nicotine vaping products in these countries where smoking populations are predominantly poorer. The higher awareness and use of nicotine vaping products in high income countries with moderately (e.g. Canada, New Zealand) and less (e.g. England, United States) restrictive policies, is likely due to the greater availability and affordability of nicotine vaping products.

The Korean economy has been significantly affected by the emergence of China. It is now the largest market for Korean exports and a major supplier of its low-cost imports but has at the same time become a serious challenger to Korea in the world markets for manufacturing exports. This paper investigates changes in China's export structure and its effect on Korea, and bilateral trade between the two. It also examines the motives for Korean investment in China and its effect on bilateral trade and cross-border production networks. [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]

This paper empirically examines whether three East Asian stock markets, namely, those of China, Japan and South Korea, are individually and/or jointly efficient, and whether contagion exists between the cointegrated markets. While individual market efficiency is examined through testing for the random walk hypothesis, joint market efficiency is examined through testing for cointegration and contagion. The present study finds that the hypothesis of individual market efficiency is strongly rejected for the Chinese stock market, but not for the Japanese and the South Korean stock markets. However, when testing for cointegration, market efficiency is strongly rejected for all these markets. We take a simple case of contagion and find that although there is a long-term relationship among the three markets, the contagion hypothesis cannot be rejected only between Japanese and South Korean stock markets, indicating short-run portfolio diversification benefits from these two markets.

In June 2010, the People's Republic of China and Taiwan signed the Economic Cooperation Framework Agreement (ECFA), a preferential trade agreement, which is arguably the most important agreement between China and Taiwan. In this paper, we analyze ECFA and investigate its implications for South Korea since China is South Korea's largest trade partner and Taiwan is its sixth largest. We find that ECFA will have significant political and economic implications for South Korea due to China's role in East Asia and South Korea's competition with Taiwan in the China market.

This paper examines trades and trade relationships among China, Japan, and South Korea. It shows that China possesses a large comparative advantage in labor-intensive products, while Japan and Korea maintain large comparative advantages in capital-intensive products. Using quarterly data from 1981 to 2001, the paper evaluates the effect of yen depreciation on the exports of China and South Korea. Our empirical results prove a positive impact of depreciation of yen on China's exports but a negative impact on Korea's exports. This finding suggests that Japan is competing with South Korea in terms of exports, but not with China. [ABSTRACT FROM AUTHOR]

Background It has been suggested that live attenuated influenza vaccine (LAIV) may be less effective in older individuals because of prior wild-type influenza infections. LAIV is currently approved in the United States, South Korea and Hong Kong for individuals 2–49 years of age. Objective To examine data from previously published pediatric studies to determine the efficacy of LAIV in various age groups. Methods Four studies in which the subject age range exceeded 36 months were identified: one 2-year study comparing LAIV with placebo and three 1-year studies comparing LAIV with trivalent inactivated influenza vaccine (TIV). Efficacy against any strain regardless of antigenic similarity to vaccine was analyzed by age; age groups were based on the study design and sample size. A logistic regression model was used to assess whether age, as a continuous variable, was an effect modifier on LAIV efficacy. Results The efficacy of LAIV did not vary with age in children aged 15–84 months compared with placebo or in children aged 6 months to 17 years compared with TIV. Conclusions The available data from prospective, randomized studies in children does not support the concept that prior repeated exposure to influenza, either through wild-type infection or vaccination with live, attenuated or inactivated vaccines, reduces the efficacy of LAIV compared with placebo or TIV. The decreased immunologic responses to LAIV reported in older individuals or those with pre-existing immunity do not appear to translate into reduced protection from influenza in children.

The impressive economic growth in a select group of Asian economies in the last several decades prompts some to argue that authoritarianism helps rapid economic growth while democracy hampers it. In this paper, we used the panel data approach to test this hypothesis for seven Asian economies, including South Korea, Singapore, and China. Our results reject the strong version of this hypothesis but fail to reject the weak version of it. Specifically, we found insignificant impacts of political freedom but significant effects of economic freedom on advancing economic convergence in these economies. [ABSTRACT FROM AUTHOR]

Background: China witnessed a surge of Omicron infections after abandoning 'zero COVID' strategies on 7 December 2022. The authorities report very sparse deaths based on very restricted criteria, but massive deaths are speculated. Methods: We aimed to estimate the COVID‐19 fatalities in Mainland China until summer 2023 using the experiences of Hong Kong and of South Korea in 2022 as prototypes. Both these locations experienced massive Omicron waves after having had very few SARS‐CoV‐2 infections during 2020–2021. We estimated age‐stratified infection fatality rates (IFRs) in Hong Kong and South Korea during 2022 and extrapolated to the population age structure of Mainland China. We also accounted separately for deaths of residents in long‐term care facilities in both Hong Kong and South Korea. Results: Infection fatality rate estimates in non‐elderly strata were modestly higher in Hong Kong than South Korea and projected 987,455 and 619,549 maximal COVID‐19 deaths respectively, if the entire China population were infected. Expected COVID‐19 deaths in Mainland China until summer 2023 ranged from 49,962 to 691,219 assuming 25–70% of the non‐elderly population being infected and variable protection of elderly (from none to three‐quarter reduction in fatalities). The main analysis (45% of non‐elderly population infected and fatality impact among elderly reduced by half) estimated 152,886–249,094 COVID‐19 deaths until summer 2023. Large uncertainties exist regarding potential changes in dominant variant, health system strain and impact on non‐COVID‐19 deaths. Conclusions: The most critical factor that can affect total COVID‐19 fatalities in China is the extent to which the elderly can be protected. [ABSTRACT FROM AUTHOR]

This study estimates long‐term PM2.5 exchange flux between the atmospheric boundary layer (ABL) and free troposphere (FT) in the North China Plain. The effect of PM2.5 long‐range transport (LRT) on air quality in downwind regions is also assessed. The PM2.5 exchange fluxes are calculated based on a mass budget method with data from WRF‐Chem simulations, during wintertime months (November, December, and January) in 2014, 2016, and 2017 (represent moderate, heavier, and less polluted years). The overall PM2.5 exchange exhibits clear topographical correlation and diurnal variation. The plain area is characterized by a considerable upward flux of −0.13 μg m−2 s−1 (in a 3‐year average), acting as an effective source for LRT. ABL height variation contributes significantly to the diurnal cycle of PM2.5 vertical exchange. Over the mountainside and ridge areas, the PM2.5 exchange flux is downward and its diurnal variation is weak, due to the dominant cross‐mountain descent flows. Four LRT patterns in the FT are identified, that is, eastward, southward, recirculation, and local stagnation. They can affect air quality in Northeast China, Yangtze River Delta, South Korea, and Japan. Indicating with averages and standard deviations, the PM2.5 concentration increases (relative contribution) for these four target regions over the 3‐year winter period are respectively 5.5 ± 4.8 μg m−3 (12.6 ± 10.9%), 4.6 ± 4.5 μg m−3 (8.4 ± 6.4%), 4.4 ± 3.9 μg m−3 (5.2 ± 4.4%), and 1.6 ± 0.9 μg m−3 (2.6 ± 1.6%). While the maximum impacts can be 36.7 μg m−3 (59%), 31.1 μg m−3 (41%), 25.7 μg m−3 (30%), and 7.2 μg m−3 (13%), respectively. Plain Language Summary: The PM2.5 exchange between the boundary layer and the free troposphere is a key process directly affecting air pollution transport and influence scale. This study estimates the PM2.5 vertical exchange flux over the North China Plain (NCP) during wintertime in 2014, 2016, and 2017, and quantifies the impact of the subsequent long‐range transport on air quality in downstream areas. The long‐term average PM2.5 exchange flux is closely related to the topographic distribution and has diurnal variation characteristics. The plain area is characterized by considerable PM2.5 vertical outflow, allowing the pollutants to be transported long distances in the free troposphere. There are four transport patterns with the main affected areas being the Yangtze River Delta, Northeast China, South Korea, and Japan, as well as the NCP itself. PM2.5 concentration increases due to the long‐range transport for these areas are quantified. These results provide a more solid understanding of atmospheric transport and large‐scale air pollution. Key Points: PM2.5 vertical exchange flux over the North China Plain is characterized by topographical distribution and diurnal variationThe plain area provides an effective PM2.5 source for long‐range transport in the free troposphere with a seasonal average upward flux of −0.13 μg m−2 s−1Four long‐range transport patterns are identified and PM2.5 concentration contributions to downstream regions are quantified [ABSTRACT FROM AUTHOR]

Several polygenic risk scores (PRSs) have been developed to predict the risk of colorectal cancer (CRC) in European descendants. We used genome‐wide association study (GWAS) data from 22 702 cases and 212 486 controls of Asian ancestry to develop PRSs and validated them in two case‐control studies (1454 Korean and 1736 Chinese). Eleven PRSs were derived using three approaches: GWAS‐identified CRC risk SNPs, CRC risk variants identified through fine‐mapping of known risk loci and genome‐wide risk prediction algorithms. Logistic regression was used to estimate odds ratios (ORs) and area under the curve (AUC). PRS115‐EAS, a PRS with 115 GWAS‐reported risk variants derived from East‐Asian data, validated significantly better than PRS115‐EUR derived from European descendants. In the Korea validation set, OR per SD increase of PRS115‐EAS was 1.63 (95% CI = 1.46‐1.82; AUC = 0.63), compared with OR of 1.44 (95% CI = 1.29‐1.60, AUC = 0.60) for PRS115‐EUR. PRS115‐EAS/EUR derived using meta‐analysis results of both populations slightly improved the AUC to 0.64. Similar but weaker associations were found in the China validation set. Individuals among the highest 5% of PRS115‐EAS/EUR have a 2.52‐fold elevated CRC risk compared with the medium (41‐60th) risk group and have a 12% to 20% risk of developing CRC by age 85. PRSs constructed using results from fine‐mapping and genome‐wide algorithms did not perform as well as PRS115‐EAS and PRS115‐EAS/EUR in risk prediction, possibly due to a small sample size. Our results indicate that CRC PRSs are promising in predicting CRC risk in East Asians and highlights the importance of using population‐specific data to build CRC risk prediction models.

Based on a perspective that understands the South Korean perception of the People's Republic of China (PRC) as resulting considerably from Korea's historical experience of its tributary relationship with China, this study explains what significant implications a South Korean understanding of the historical tributary order may have for its perceptions of a "new China" and preferences for the Republic of Korea's (ROK; South Korea) foreign policy directions. In premodern times, Korea had a special experience with China. Korean kingdoms shared with imperial China a tributary relationship in which the former was positioned as the latter's tributary state. South Koreans in general understand the traditional Chinese–Korean tributary relationship negatively. This negative understanding of the historical tributary relationship affects the South Korean perception of a "new China." Many South Koreans see the PRC that seeks to reconstruct the traditional tributary order as a rising threat. South Korean perceptions of both the premodern tributary relationship and its possible restoration by the PRC may determine their foreign policy preferences. While the established conservatives prioritize the ROK–US alliance and the progressives give priority to the ROK–PRC partnership, South Koreans as a whole prefer the United States over China as the ROK's security partner and balancing against China over bandwagoning with it.

Biological invasion has been a serious global threat due to increasing international trade and population movements. Tracking the source and route of invasive species and evaluating the genetic differences in their native regions have great significance for the effective monitoring and management, and further resolving the invasive mechanism. The spotted lanternfly Lycorma delicatula is native to China and invaded South Korea, Japan, and the United States during the last decade, causing severe damages to the fruits and timber industries. However, its global phylogeographic pattern and invasion history are not clearly understood. We applied high‐throughput sequencing to obtain 392 whole mitochondrial genome sequences from four countries to ascertain the origin, dispersal, and invasion history of the spotted lanternfly. Phylogenomic analyses revealed that the spotted lanternfly originated from southwestern China, diverged into six phylogeographic lineages, and experienced northward expansion across the Yangtze River in the late Pleistocene. South Korea populations were derived from multiple invasions from eastern China and Japan with two different genetic sources of northwestern (Loess Plateau) and eastern (East Plain) lineages in China, whereas the each of Japan and the United States had only one. The United States populations originated through single invasive event from South Korea, which served as a bridgehead of invasion. The environmental conditions, especially the distribution of host Ailanthus trees, and adaptability possibly account for the rapid spread of the spotted lanternfly in the native and introduced regions.

During June–July 2020, the record‐breaking flooding in the recent four decades struck the plum rain belt over China, Japan, and Korea. Concurrent with this persistent heavy rainfall, pronounced Indian Ocean basin warming (IOBW) was observed, following the previous El Niño event in the transition to La Niña‐like mean state this summer. This tropical Indo‐Pacific large‐scale thermal condition provided favorable conditions for rainfall surpluses over the plum rain belt via the western North Pacific anticyclone. Superimposed on the tropical Indo‐Pacific large‐scale thermal condition, an extraordinary long‐lasting and quasistationary Madden‐Julian Oscillation (MJO) active phase persisted in the Indian Ocean throughout June–July 2020, lasting for 59 days. The MJO‐associated teleconnection was mainly responsible for the extreme rainfall over the plum rain belt, which was facilitated by the conducive large‐scale Indo‐Pacific oceanic‐atmospheric condition. Plain Language Summary: The East Asian rainy season (commonly called the plum rain, also known as Meiyu in China, Baiu in Japan, and Jangma in Korea), is caused by rainfall along a persistent stationary front. The plum rain season usually starts in June and persists into the middle of July. During June–July 2020, the region of the plum rain belt over China, Japan, and Korea, was ravaged by the strongest flooding in decades with catastrophic losses. The physical mechanisms driving this extreme flooding remains unclear. Concurrent with this persistent rainfall surpluses, the Indo‐Pacific oceans featured a developing La Niña‐like state in the eastern tropical Pacific and pronounced sea surface temperature warming in the Indian Ocean basin. Although these Indo‐Pacific thermal conditions can provide a favorable large‐scale background for the rainfall surpluses over East Asia, they cannot explain the extreme rainfall amount over the plum rain belt during 2020. We show that an exceptionally long‐lasting and quasistationary Madden‐Julian Oscillation activity over the Indian Ocean was the key reason for this extreme event. Key Points: The rainfall amount over the East Asian plum‐rain belt during summer 2020 was the largest in the recent four decadesThe intense flooding coincided with an exceptionally persistent Madden‐Julian Oscillation (MJO) active phase in the Indian Ocean throughout June and JulyThis extraordinary MJO activity was facilitated by the conducive pantropic background oceanic‐atmospheric conditions [ABSTRACT FROM AUTHOR]

This article examines the origin, process, and outcome of an understudied, but important multilateral climate change negotiation: the OECD negotiation to restrict export finance for coal‐fired power projects. It assesses how the United States – the OECD's most powerful member – led the negotiations, and how Japan, South Korea, and China – a non‐OECD state – affected the negotiation's outcome. It shows how internal and external dynamics of the negotiation under the shadow of China's rising market influence shaped the preferences of Japan and South Korea in such a way that constrained US attempts to build new rules in curbing coal export finance. This research illustrates the collective action problem in an increasingly fragmented global governance landscape driven by transitions in global power. Contrary to critics that have identified China's participation in multilateral organizations as weakening the global liberal order, this research shows that a 'club‐based' approach to this liberal order proved ineffective absent China's participation. Regardless of the global ECA regime's imperfect nature, the new OECD guidelines have in some way catalyzed a movement among financial institutions, both public and private, to stay away from coal.

We evaluate the direct impact of China trade shock on the Korean labour market following the approach of Acemoglu, Autor, Dorn, Hanson, and Price (Journal of Labor Economics, 2016, 34, S1). Using firm‐ and industry‐level data for the period 1993–2013, our direct estimates imply that the net employment effect of the China shock in the manufacturing sector is the creation of 0.52 million jobs. The positive impact is mostly driven by China's rising demand for intermediate inputs and capital goods from Korea to support its export expansion to the global economy. The import‐competition channel plays a negligible role in manufacturing employment because it creates temporary jobs that merely compensate for the loss in permanent jobs. By contrast, over the same period, the average wage declined by 2.4%, and income inequality, measured as the gap between the high‐ and low‐income quantile, grew substantially in manufacturing. In addition, we find that the direct effect of China shock lowers labour market concentration by shifting workers from big firms to small‐ and medium‐sized firms. [ABSTRACT FROM AUTHOR]

In response to growing public scrutiny of ethical business practices, corporations have become actively engaged in reporting their social and environmental performances publicly. Drawing on the institutional theory to explain the growing diffusion of corporate social responsibility (CSR) reporting on a global, yet distinctively specific level of adoption, this study examines the level of transparency signaling in CSR reports in three countries: the United States, South Korea, and China. In addition, within each country, the study compares the level of transparency signaling between environmentally sensitive and nonsensitive industries. Using a computer‐aided content analysis program, DICTION 7.0, the study analyzed 181 CSR reports from 2014 to 2017. Results show that the three dimensions of transparency signaling—participation, substantial information, and accountability—in CSR reports varied across different countries. Firms in the United States and South Korea showed higher scores in the participation and accountability dimensions than China, whereas firms in China showed relatively high scores in the substantial information dimension. The theoretical and practical implications are discussed. [ABSTRACT FROM AUTHOR]

Objective: Lower urinary tract symptoms (LUTS) in males can reduce patients' quality of life (QoL) and affect sexual function and satisfaction. Although this has been documented in the US, Canada, Germany, Italy, UK, and Sweden, data are limited on the effects of LUTS on QoL and sexual function in Asian men. The present subgroup analysis of an Internet‐based survey correlated the incidence of male LUTS by severity and category with self‐assessed QoL and sexual function and satisfaction measures. Methods: Males aged ≥40 years were randomly selected from consumer survey panels in China, Taiwan, and South Korea. LUTS were defined using the International Continence Society (ICS) 2002 symptom definitions; symptom severity was assessed by the International Prostate Symptom Score (IPSS). The effect of LUTS on QoL was assessed using Patient Perception of Bladder Condition (PPBC) and IPSS QoL scores. Sexual function and satisfaction were assessed using the International Index of Erectile Function (IIEF). Results: Men with moderate‐to‐severe LUTS and overlap of voiding, storage, and post‐micturition symptom categories reported dissatisfaction with their QoL and sexual function. LUTS severity was negatively correlated with IIEF scores. Overlap of LUTS categories had a greater effect on QoL and sexual satisfaction than the incidence of just 1 LUTS. Conclusion: The findings of the present study suggest that LUTS is prevalent in >60% of Asian males aged ≥40 years and is associated with reduced QoL and sexual function, particularly in those with overlap of LUTS categories and greater symptom severity.

Objective: The aim of this study was to compare the prevalence of behavioural and psychological symptoms of dementia (BPSD) in cognitively impaired elderly residents of long‐term care facilities in East Asia and to explore the factors associated with these patterns. Methods: This was a cross‐sectional survey of BPSD in cognitively impaired elderly residents of long‐term care facilities in Japan, South Korea, China, Taiwan, and Thailand. The Mini‐Mental State Examination, Clinical Dementia Rating (CDR), and Neuropsychiatric Inventory, Nursing Home version (NPI‐NH), were used to assess cognitive status, dementia severity, and BPSD, respectively. NPI‐NH subscale severity scores were multiplied by frequency scores to obtain the subscale scores and aggregated into two groups based on score (clinically insignificant = 1– 3; clinically significant ≥4). Results: Data from 662 people were analyzed. Median age, median Mini‐Mental State Examination scores, and median CDR scores differed significantly among the seven study sites. The prevalence of BPSD varied from 64% in Taiwan to 100% in dementia care units in Japan, and the median total NPI‐NH scores ranged from 2 in Taiwan to 14 in dementia care units in Japan. After stratification of the sample by dementia severity and clinical significance of NPI‐NH scores, differences in the prevalence of clinically significant BPSD were mostly observed among facilities dedicated to dementia patients in the CDR 1 group. In the CDR 3 group, the prevalence of some clinically significant BPSD, such as apathy, was high even among study sites with low median total NPI‐NH scores. Conclusions: Our findings may suggest referral and selection biases in the study sites. Future prospective studies are needed to address the impact of environmental and care factors on the occurrence of BPSD in Asian countries. [ABSTRACT FROM AUTHOR]

The online shopping craze in South Korea has been ongoing for more than a decade, but in China, online shopping is experiencing tremendous growth, with 64 million additional shoppers per year. Consumers in Asia are among the world's most prolific online shoppers. This study compares the evolution, cycle, and stages of the online shopping markets in South Korea and China. Using the fast-expanding market model as an initial analytical framework and multiple case approach, we find that Chinese online shopping corresponds to the take-off stage of a successful cluster, in which significant opportunities are still present in Chinese Tier 3 and Tier 4 cities. Conversely, the South Korean online market is nearing saturation, though major foreign players are still entering this perceived lucrative marketplace. © 2016 Wiley Periodicals, Inc.

The purpose of this research is to quantitatively compare everyday situational experience around the world. Local collaborators recruited 5,447 members of college communities in 20 countries, who provided data via a Web site in 14 languages. Using the 89 items of the Riverside Situational Q-sort (RSQ), participants described the situation they experienced the previous evening at 7:00 p.m. Correlations among the average situational profiles of each country ranged from r = .73 to r = .95; the typical situation was described as largely pleasant. Most similar were the United States/Canada; least similar were South Korea/Denmark. Japan had the most homogenous situational experience; South Korea, the least. The 15 RSQ items varying the most across countries described relatively negative aspects of situational experience; the 15 least varying items were more positive. Further analyses correlated RSQ items with national scores on six value dimensions, the Big Five traits, economic output, and population. Individualism, Neuroticism, Openness, and Gross Domestic Product yielded more significant correlations than expected by chance. Psychological research traditionally has paid more attention to the assessment of persons than of situations, a discrepancy that extends to cross-cultural psychology. The present study demonstrates how cultures vary in situational experience in psychologically meaningful ways. [ABSTRACT FROM AUTHOR]

Objective This study aims to synthesise evidence on time trends of dementia prevalence in East Asian countries including Japan, China, South Korea and Taiwan and assess the impact of the societal changes on future prevalence. Method Relevant reviews and recent nationwide studies in East Asia were identified to investigate changes in prevalence of dementia over time taking into account the potential impact of methodological factors and study designs. Results The robust evidence that has been interpreted to suggest a substantial increasing trend over time is less compelling once fundamental differences in study methods and populations across individual surveys are considered. In Japan, longitudinal studies in small areas suggest the potential increase of prevalence after 2000. Increasing trends in China, South Korea and Taiwan over the last 20-30 years are based on the literature review without adjustment for methodological differences. Economic development and huge societal changes alongside the rise of non-communicable disease in East Asia could lead to increasing prevalence of dementia in the future once those cohorts with high risk of dementia reached their older age. Conclusion Current evidence is not sufficient to suggest increasing trends of dementia prevalence in East Asia. Longitudinal studies with representative samples and stable methodology are needed to provide fundamental information of the epidemiology of dementia and identify important risk factors in East Asian societies. © 2015 The Authors.

Background China has a great variety of geographical and climatic conditions, and several cultural differences exist within the country; thus, understanding the regional and seasonal differences that cause skin sensitivities in this country is important. Objective The aim of this study was to assess skin sensitivity of women from six cities in China and from South Korea during the winter and summer seasons to aid the development of suitable and effective dermatological products. Methods This multicentre study included 754 healthy female volunteers, and was conducted in the winter (between January and March) and summer (between June and July) of 2011. Patch tests were performed using 0.5% sodium lauryl sulphate (SLS) aqueous solution and 0.15% retinol in 1,3-butylene glycol on the back of the volunteers. Simultaneously, stinging tests were performed on their cheeks by using 5% lactic acid solution and 0.001% capsaicin solution, each in a negative control vehicle (distilled water and 10% ethanol solution, respectively). Results The patch test results showed that the subjects in Beijing and Shenyang were more sensitive to SLS, retinol and lactic acid in the winter than were those in Guangzhou, Shanghai, Wuhan, Chengdu and South Korea. The stinging test results revealed that the subjects in Beijing were more neurosensitive to lactic acid in the winter; however, during the same season, the subjects from Shanghai and Guangzhou were significantly more neurosensitive to capsaicin. Conclusion Our observations indicate that skin sensitivity differs considerably between women from different parts of China and South Korea. We recommend that these differences be considered during the development of cosmetic products in these countries. [ABSTRACT FROM AUTHOR]

Why has Korean migration policy been ethnicized? This research mainly aims to explain ethnic preference in Korea's immigration policy through the lens of Korean nationalism. The influx of ethnic Koreans in China (or Joseonjok) since the early 1990s has created a new dilemma for the South Korean government, which has long claimed to be the only legitimate polity of the Korean nation. The discrepancy between the legal citizenship and ethnicity of the Korean- Chinese workers in Korean society has forced the Korean state to redefine both legal and discursive national boundaries. This study analyzes the bifurcation of the Korean state discourses regarding Korean- Chinese workers in Korean society. [ABSTRACT FROM AUTHOR]

In May 2012, China, Japan, and South Korea (CJK) signed a trilateral investment agreement-their first legal agreement on trilateral economic cooperation. This article argues that the diffusion of liberal investment rules in the trilateral agreement was circumscribed by China's market power. It examines the evolution of CJK policies on investment agreements and how these policies clashed in the negotiation of the trilateral deal. During the last decade, Japan and Korea have secured agreements with Southeast Asian nations that liberalize rules governing investment but they were unable to push China toward preestablishment liberalization in the trilateral agreement. As a result, there is a bifurcation of investment rules in East Asia with more liberal rules among Japan, Korea, and Southeast Asia than any that the three share with China. [ABSTRACT FROM AUTHOR]

ABSTRACT Recent developments in the biopharmaceutical industry in Taiwan, South Korea and China bear witness to the transformation of these states in nurturing an innovation-based industry. This article argues that the segmentation of the value chain of the biopharmaceutical industry has provided industrializing countries with a window of opportunity. These East Asian states have modified their former catching-up approaches by establishing a more effective institutional platform that can attract knowledge-creation players to the industry. Through case studies, the authors show that the Taiwan state's promotion of the biopharmaceutical industry has been based on an incremental approach; existing state policies have been modified to cope with the demands of the industry, which has resulted in the continuation of its SME-based industrial structure. The methods of the Korean state have been more radical, in that the policies that previously favoured the chaebols have gradually been reoriented toward the promotion of smaller, science-based firms that now co-exist alongside the chaebols. Finally, the Chinese state and local governments have sought to promote this innovation-based industry by building biotech parks. This approach has resulted in a boom in new science firms, which have become increasingly isolated from the flourishing domestic SOE-led market. [ABSTRACT FROM AUTHOR]

This Introduction sets the scene for the Symposium. It considers the governance value of civic engagement, along with civic engagement as identifiable modes of governance. Such matters are embraced in the subsequent analyses of significant developments and experience in South Korea, the Philippines, Australia, Hong Kong and China.

Gao Q, Yoo J, Yang S-M, Zhai F. Welfare residualism: a comparative study of the Basic Livelihood Security systems in China and South Korea Int J Soc Welfare 2011: 20: 113-124 © 2010 The Author(s), International Journal of Social Welfare © 2010 Blackwell Publishing Ltd and International Journal of Social Welfare. In this article, the Basic Livelihood Security (BLS) systems of China and South Korea are compared. The purpose of BLS is to provide a safety net for poor families, particularly the unemployed and the retired who were hard-hit by recent economic reforms and crises. A common characteristic of the two systems is residual welfare marked by strict eligibility rules and limited coverage. Both systems are subordinate to the primary goal of economic growth and therefore only compensate for the very disadvantaged left behind by market competition. Neither system is particularly effective in achieving its original antipoverty goals. However, South Korea's provision of self-support programs to supplement cash transfers has helped individuals to move from welfare to work, and thus has implications for China's BLS system. Both countries need to put more emphasis on equity and social justice in their ongoing reforms and expansions of BLS. [ABSTRACT FROM AUTHOR]

As suggested in a growing literature that securitizes the phenomenon of refugee migration and analyzes it as a national as well as a regional security issue, the growing number of North Korean border-crossers has far-reaching political implications for both North Korea and the international community. Studies have argued that refugees could contribute significantly to democratic change in their home countries by assisting and actively participating in the struggle of the domestic opposition, even sparking regime instability and eventual regime breakdown. Much of the North Korean refugee research has focused on the human rights issues faced by the refugees, but a largely unexplored area of the refugee research concerns the political consequences of the refugee flight for the current regime in Pyongyang. This article examines whether North Korean refugees are expected to play the role of political opposition in exile by raising the following four questions: (i) Are the refugees political dissidents? (ii) Are they a resourceful critical mass? (iii) Does exit always lead to regime instability? and (iv) Would China and South Korea encourage exile politics against the current North Korean regime? The article contends that the North Korean refugee community does not currently represent a critical mass that can trigger instability of the Pyongyang regime. Most of the North Korean refugees are not political dissidents, nor have they organized into any resourceful critical mass capable of generating a threat to their home country. In addition, people's exit does not necessarily destabilize the regime as it can sometimes yield a positive political effect by driving out dissidents' voices. Furthermore, several of the receiving countries, in particular, China and South Korea, would not encourage exile dissident movements against North Korea for fear of Pyongyang's collapse. The North Korean regime's stability does not seem to be threatened by the current refugee situation, although the potential of refugees becoming a critical threat should not be discounted should people's exit ever reach the point of developing into an uncontrollable mass exodus.

In response to calls regarding the applicability of marketing scales in other cultures, the current study re-examined the psychometric properties and measurement equivalence of the consumer vanity scale. The sample consisted of 723 undergraduate participants from China, South Korea and Thailand. Results revealed that the 21-item, four-factor (physical concern, physical view, achievement concern and achievement view) model of consumer vanity exhibited a satisfactory condition of psychometric properties across three samples. Multigroup analysis also revealed that the consumer vanity scales have partial factorial invariance. More specifically, the results as related to latent means comparison revealed that there are differences and similarities between the four dimensions of consumer vanity among Chinese, South Korean and Thai participants. Implications and future research directions are discussed. [ABSTRACT FROM AUTHOR]

There have been fewer cross-national comparative works on social mobility in East Asian countries than in Western countries. The present study aims to explore the similarities and differences of intergenerational social mobility in three East Asian countries and to examine whether the Featherman–Jones–Hauser (FJH) hypothesis would fit well into the mobility tables for Japan, Korea, and China. Log-linear and log-multiplicative models are applied to the mobility tables of respondents’ occupations according to the father's occupation in the three countries. The analysis of relative rates of mobility did not completely support the FJH hypothesis in a strict sense, even though it reasonably accounts for the total association of origin and destination in the three countries. My analysis demonstrates that a level of social fluidity has been higher in Korea and China than in Japan. Focusing on how relative mobility patterns differ between the three countries, intergenerational mobility in Korea is characterized by lower rates of class inheritance compared to Japan, while there seems to be a similarity between the patterns of social fluidity in Japan and Korea, even though they are to a certain extent deviant from Erikson and Goldthorpe's core model. In contrast to Korea, class inheritance rates in China are almost as large as in Japan. However, the mobility pattern between classes appears to differ substantially between the post-socialist and two capitalist countries. In particular, both downward and upward mobility between the white collar bloc and the unskilled manual position are more pervasive in China than in Japan and Korea. These results imply that sociologists interested in cross-national comparison of the social mobility between the East Asian countries should pay attention to both political institutions and the local labor market situatuion which can substantially affect social mobility.

This article examines the question of how serious President Eisenhower was in contemplating the use of nuclear weapons on the Korean peninsula and Chinese mainland. To do this, it surveys Eisenhower's thinking and policies about the issue from 1953 to 1968 in regard to maintaining the security of South Korea. In contrast to many in the literature who argue that Eisenhower would have been very reluctant to authorize their use or who downplay the significance of his many statements about the use of nuclear weapons, it maintains that the president was much more willing to use nuclear compellent force than many have supposed. In regard to Eisenhower's reputation, this article adopts a post-revisionist stance that questions the consensus in the literature that he viewed them as instruments of deterrence, not war fighting. It also suggests that more research should be initiated to investigate the relationship between presidents’ national security policies, commitments, and the option of nuclear compellence.

The tectonic history of the Okcheon Metamorphic Belt (OMB) is a key to understanding the tectonic relationship between South Korea, China and Japan. The petrochemistry of 150 psammitic rocks in the OMB indicates that the depositional environment progressively deepened towards the northwest. These data, combined with the distribution pattern of oxide minerals and the abundance of carbonaceous material, support a half­graben basin model for the OMB. Biotite and muscovite K­Ar dates from metasediments in the central OMB range from 102 to 277 Ma. K­Ar ages of 142–194 Ma are widespread throughout the area, whereas the older ages of 216–277 Ma are restricted to the metasediments of the middle part of the central OMB. The younger (Cretaceous) ages are only found in metasediments that are situated near the Cretaceous granite intrusions. The 216–277 Ma dates from weakly deformed areas represent cooling ages of M1 intermediate pressure/temperature (P/T) metamorphism. The relationship between age distribution and deformation pattern indicates that the Jurassic muscovite and biotite dates can be interpreted as complete resetting ages, caused by thermal and deformational activities associated with Jurassic granite plutonism. Well-defined 40Ar/39Ar plateau ages of 155–169 Ma for micas from both metasediments and granitic rocks can be correlated with the main Jurassic K­Ar mica ages (149–194 Ma). U­Pb zircon dates for biotite granite from the southwest OMB are 167–169 Ma. On the basis of the predominantly Jurassic igneous and metamorphic ages and the uniformity of d002 values for carbonaceous materials in the study area, it is suggested that the OMB has undergone amphibolite facies M2 metamorphism after M1 metamorphism. This low P/T M2 regional thermal metamorphism may have been caused by the regional intrusion of Jurassic granites. The OMB may have undergone tectono­metamorphic evolution as follows: (i) the OMB was initiated as an intraplate rift in the Neoproterozoic during break-up of Rodinia, and may represent the extension of Huanan aulacogen within the South China block; (ii) sedimentation continued from the Neoproterozoic to the Ordovician, perhaps with several unconformities; (iii) M1 intermediate P/T metamorphism occurred during the Late Paleozoic due to compression caused by collision between the North and South China blocks in an area peripheral to the collision zone; and (iv) during the Early to Middle Jurassic, north-westward subduction of the Farallon­Izanagi Plate under the Asian Plate resulted in widespread intrusion of granites, which triggered M2 low P/T regional thermal metamorphism in the OMB. This event also formed the dextral Honam shear zone at the boundary between the OMB and Precambrian Yeongnam massif. [ABSTRACT FROM AUTHOR]

Previous studies of firms that issue seasoned equity in the US and Japan have found that these firms significantly underperform over the long-run subsequent to the issue. I offer further evidence of this by examining Japanese seasoned offerings (SEOs) from 1975 to 1992. I find similar results for firms issuing seasoned equity in Hong Kong. However, I also find that Korean SEOs generate insignificant abnormal returns over a 36-month period following the issue. These results suggest that the asymmetric information argument offered for the US and Japanese markets do not always hold, especially in markets where the regulatory and market structures vary greatly. Cross-sectional results suggest that younger firms tend to perform worse than older firms. [Copyright &y& Elsevier]

The relationship of state policy to economic growth in such countries as Japan, South Korea, Taiwan and Singapore has been appreciated by some social scientists for quite some time while; Hong Kong seemed to be the deviant case. The article focuses on economic growth in Hong Kong, which was also predicated on substantial state intervention. However, state ownership of land, the provision of collective consumption, and the supply of basic commodities by the People's Republic of China, at less than market prices, are the defining characteristics. Although many commentators have noted the advantages of Hong Kong's geographical position in aiding rapid industrialization, her political status may have been equally important. Because it is administering a colony, Hong Kong's government has been able to avoid the types of political pressures that have often led to mushrooming public sectors, disproportionate investment in "non-productive" activities and resultant financial difficulties in many third world countries.

The purpose of this study was to investigate how the aging problem in China was reflected in Yun-bian, an area where the Korean-Chinese converge, and to forecast future aging issues. The findings of this study revealed that 60% of the elderly identified themselves as healthy or normal, while 30.8% of them identified themselves as having a disease. Over 80% (80.6%) of the population who had an illness were elderly. The most prevalent diseases were hypertension, angina pectoris, arthritis, cerebral thrombosis, and digestive and respiratory disease. The leading causes of death were cerebrovascular disorders, accidents, malignant tumors, and heart disease. Among the Yun-bian elderly, 68.8% were found to be cared for by their families, with 30.8% of them living with their offspring. Only 0.45% of the Yun-bian elderly were found to be living in social welfare centers. The medical treatment services provided were either community-centered or hospital-centered. It was concluded that reinforcement for administration and organization of the health-care services, policy development regarding medical insurance for the aged, professional health-care provider education for the elderly, and health-care program development for the elderly are needed.
