Trust is key: Determinants of false beliefs about climate change in eight countries

Science has established the human-caused nature of climate change, yet the prevalence of climate-related misinformation persists, undermining public understanding and impeding collective action. Strikingly, existing research on belief in misinformation about climate change has disproportionately focused on WEIRD (Western, Educated, Industrialized, Rich, and Democratic) countries. To move beyond this, our online survey (N = 8541) includes high-income countries in North America (US), Western Europe (France, Germany, UK) and East Asia (Japan), as well as an upper-middle income country in South America (Brazil) and lower-middle income countries in South Asia (India and Pakistan). By examining the interplay of news media usage, information sources, and trust in these sources, we advance our understanding of how these factors influence belief in climate change-related misinformation in diverse socio-cultural contexts. Across countries, we found that the strongest determinants of belief in misinformation about climate change were identifying as right-wing (compared with left-wing), consuming less offline news, having less trust in scientists, environmental activists, as well as international organizations, and having more trust in politicians, celebrities, and energy companies. Overall, trust in sources of information about climate change and demographic variables were much stronger predictors of belief in misinformation about climate change than reported news consumption (online, offline or on social media). These findings suggest that trust is key to understanding belief in false information about climate change.

Neoadjuvant Chemotherapy Improves Feasibility of Larynx Preservation and Prognosis in Resectable Locally Advanced Cervical Esophageal Cancer.

The optimal strategy for cervical advanced esophageal cancer remains controversial in terms of oncologic outcome as well as vocal and swallowing function. Recently, in East Asian countries, neoadjuvant chemotherapy (NAC) has been a standard strategy for advanced esophageal cancer. This study included 37 patients who underwent NAC, and 33 patients who underwent definitive chemoradiation therapy (dCRT) as larynx-preserving treatment for locally advanced cervical esophageal cancer from 2016 to 2021. This study retrospectively investigated outcomes, with comparison between NAC and dCRT for locally advanced cervical esophageal cancer. Larynx preservation was successful for all the patients with NAC and dCRT. After NAC, the rate of complete or partial response was 78.4%, and 30 patients underwent larynx-preserving surgery. On the other hand, after dCRT, the complete response rate was 71.9%, and 4 patients underwent larynx-preserving salvage surgery. Overall survival (OS) and progression free survival were similar between the two groups. However, for the patients with resectable cervical esophageal cancer (cT1/2/3), the 2-year OS rate was significantly higher with NAC (79.9%) than with dCRT (56.8%) (P = 0.022), and the multivariate analyses identified only NAC and cN0, one of the two as a significantly independent factor associated with a better OS (NAC: P = 0.041; cN0, 1: P = 0.036). The study showed that NAC as larynx-preserving surgery for resectable cervical esophageal cancer preserved function and had a better prognosis than dCRT. The authors suggest that NAC may be standard strategy for larynx preservation in patients with resectable cervical esophageal cancer.

Is replacing missing values of PM2.5 constituents with estimates using machine learning better for source apportionment than exclusion or median replacement?

East Asian countries have been conducting source apportionment of fine particulate matter (PM2.5) by applying positive matrix factorization (PMF) to hourly constituent concentrations. However, some of the constituent data from the supersites in South Korea was missing due to instrument maintenance and calibration. Conventional preprocessing of missing values, such as exclusion or median replacement, causes biases in the estimated source contributions by changing the PMF input. Machine learning (ML) can estimate the missing values by training on constituent data, meteorological data, and gaseous pollutants. Complete data from the Seoul Supersite in 2018 was taken, and a random 20% was set as missing. PMF was performed by replacing missing values with estimates. Percent errors of the source contributions were calculated compared to those estimated from complete data. Missing values were estimated using a random forest analysis. Estimation accuracy (r2) was as high as 0.874 for missing carbon species and low at 0.631 when ionic species and trace elements were missing. For the seven highest contributing sources, replacing the missing values of carbon species with estimates minimized the percent errors to 2.0% on average. However, replacing the missing values of the other chemical species with estimates increased the percent errors to more than 9.7% on average. Percent errors were maximal at 37% on average when missing values of ionic species and trace elements were replaced with estimates. Missing values, except for carbon species, need to be excluded. This approach reduced the percent errors to 7.4% on average, which was lower than those due to median replacement. Our results show that reducing the biases in source apportionment is possible by replacing the missing values of carbon species with estimates. To improve the biases due to missing values of the other chemical species, the estimation accuracy of the ML needs to be improved.

Economic Development Pattern and Trade Imbalance: Comparing the U.S. with East Asia

With the development of trade globalization, East Asian countries have occupied an important position in global trade. The rise of the East Asian economy has led to a long-term trade deficit between the United States and East Asian countries, causing economic imbalance. Focusing on the economic development patterns of the United States and East Asian countries, this paper proposes a research question: How does the difference in economic development between the U.S. and East Asian countries lead to trade imbalance? This article uses comparative advantage and absolute advantage theory, Keynesian political economy, global savings glut hypothesis and the flying-geese model to provide theoretical support for the research, and then uses data from the World Bank and Bureau of Economic Analysis to further demonstrate. The last part of this paper makes an empirical analysis through case analysis and model tests. This study argues that differences in economic development lead to an international division of labor and a savings-investment gap, which in turn lead to trade imbalances.

Liberal Convergence or Differential Exclusion? Temporary Labor Migration Policy in Japan and Korea

Abstract The rapid industrialization of countries in East Asia and the resulting labor shortage are challenging established theories in research on migration policy. Studies argue that the persistence of temporary labor migration programs in this region contests the liberal convergence thesis, which suggests that democratization inevitably leads to more open migration policies. This article revisits the theoretical debate, focusing on conceptual equivalence across time and space. In a comparative policy study of Japan and Korea, we examine the development of two temporary labor migration programs (the Specified Skilled Worker program and the Employment Permit System). Our findings demonstrate how migration policies alternately intersect and diverge throughout time and across policy dimensions. The article contributes to comparative research in migration policy by highlighting the significance of historically informed and empirically equivalent analysis of migration policies.

SFTSV nucleoprotein mediates DNA sensor cGAS degradation to suppress cGAS-dependent antiviral responses.

Severe fever with thrombocytopenia syndrome virus (SFTSV) is a tick-borne RNA virus that is widespread in East and Southeast Asian countries with a high fatality rate of up to 30%. Up to now, many cytoplasmic pattern recognition receptors, such as RIG-I, MDA5, and SAFA, have been reported to recognize SFTSV genomic RNA and trigger interferon-dependent antiviral responses. However, current knowledge is not clear whether SFTSV can be recognized by DNA sensor cyclic GMP-AMP synthase (cGAS). Our study demonstrated that cGAS could recognize SFTSV infection via ectopic mitochondrial DNA, and the activated cGAS-stimulator of interferon genes signaling pathway could significantly inhibit SFTSV replication. Importantly, we further uncovered a novel mechanism of SFTSV to inhibit innate immune responses by the degradation of cGAS. cGAS was degraded in N-induced autophagy. Collectively, this study illustrated a novel virulence factor of SFTSV to suppress innate immune responses through autophagy-dependent cGAS degradation.

Structural snapshots of phenuivirus cap-snatching and transcription.

Severe fever with thrombocytopenia syndrome virus (SFTSV) is a human pathogen that is now endemic to several East Asian countries. The viral large (L) protein catalyzes viral transcription by stealing host mRNA caps via a process known as cap-snatching. Here, we establish an in vitro cap-snatching assay and present three high-quality electron cryo-microscopy (cryo-EM) structures of the SFTSV L protein in biologically relevant, transcription-specific states. In a priming-state structure, we show capped RNA bound to the L protein cap-binding domain (CBD). The L protein conformation in this priming structure is significantly different from published replication-state structures, in particular the N- and C-terminal domains. The capped-RNA is positioned in a way that it can feed directly into the RNA-dependent RNA polymerase (RdRp) ready for elongation. We also captured the L protein in an early-elongation state following primer-incorporation demonstrating that this priming conformation is retained at least in the very early stages of primer extension. This structural data is complemented by in vitro biochemical and cell-based assays. Together, these insights further our mechanistic understanding of how SFTSV and other bunyaviruses incorporate stolen host mRNA fragments into their viral transcripts thereby allowing the virus to hijack host cell translation machinery.

Factory Asia Meets Factory North America: How Far Does Latin America Get Involved in Machinery Production Networks?

International production networks in machinery industry have formed three large clusters, each of which is in East Asia, North America, and Europe. This paper investigates the recent evolvement of the connection between Factory Asia and Factory North America with highlighting the role of Latin American countries as a mediator. For this purpose, we utilized trade matrices and gravity equations to measure each country’s level of commitment to each bilateral machinery trade after controlling the size of the economies, distance, and others. Our major findings are threefold: first, Mexico is the only Latin American country that plays a connecting role between two Factories. Second, in 2010–2019, the linkage of exports to Mexico from not only China but also other East Asian countries is strengthened particularly in machinery parts and components. Third, export linkage of China with Mexico is further intensified in 2019–2021 particularly in machinery parts and components due to the US-China confrontation, the USMCA, and other factors.

Bioinformatic Analysis of Ping-Wei-San Decoction for Pulmonary Malignancy Based on UPLC-QE-Orbitrap-MS Detection

Background The traditional Chinese medicine prescription Ping-Wei-San decoction (PWS) has been used historically in East Asian countries. This study aimed to investigate the ingredients of the decoction and explore its potential role in the adjuvant treatment of pulmonary malignancies. Objectives The primary objective was to analyze the ingredients of PWS and understand its potential in the treatment of pulmonary malignancy. Methods Medical records of 143 394 patients using PWS over a decade were collected from the Affiliated Hospital of Qingdao University. UPLC-QE-Orbitrap-MS detected 13 chemical components, including 12 known components. Lung adenocarcinoma data were obtained from the TCGA-LUAD dataset, and differential genes were screened using R studio. The EVENN website and the STRING database were used to identify drug action and disease targets. Setting The study was conducted at the Affiliated Hospital of Qingdao University. Participants The study included 3147 patients with “pulmonary malignancies.” Intervention PWS was used as an adjuvant treatment. Results Network analysis revealed 10 core targets (CCNA2, CHEK1, TOP2A, CDK1, CCNB1, CCNB2, AURKA, AURKB, KIF11, and MELK) for the treatment of lung adenocarcinoma and associated pathways. Conclusion PWS may offer multifunctional efficacy in the treatment of pulmonary malignancies based on constituent analysis. Further research and clinical trials are needed to explore its potential.

Optics of spectacle lenses intended to treat myopia progression.

This is a review of the optics of various spectacle lenses that have been used in myopia control over the last 60 years, with emphasis on approximately the last 15 years.Myopia has become an increasing health problem worldwide, particularly in some East Asian countries. This has led to many attempts to slow its progression in children and reduce its endpoint value. This review is concerned with the optics of spectacle lenses for use in myopia control, from bifocal lenses to multisegment and diffusion optics lenses. Treatments are based on theories of the onset or progression of myopia. These include the hypotheses that eye growth and myopia in susceptible children may be stimulated by (1) poor accommodation response and the consequent hyperopic defocus with near vision tasks, (2) relative hyperopic peripheral refraction, and (3) high retinal image contrast as occurs in urban environments. Using spectacle lenses to slow myopia progression has a history of about 60 years. The review is laid out in approximately the order in which different types of lenses have been introduced: bifocals, conventional progressive addition lenses, undercorrection with single-vision lenses, specialized progressive addition lenses, defocus-incorporated multiple segments, diffusion optics, and concentric bifocals. In the review, some of the lenses are combined with an eye model to determine refractive errors for peripheral vision for the stationary eye and for foveal vision for the rotating eye. Numbers are provided for the reported success of particular designs in retarding myopia progression, but this is not an epidemiological paper, and there is no critical review of the findings. Some of the recent treatments, such as multiple segments, appear to reduce the eye growth and myopia progression by better than 50% over periods of up to 2 years.

Addressing cultural inertias for co-design: exploring Chinese participants’ perceptions of design games

AbstractInnovation-driven firms must adopt an open design strategy for competitiveness. Co-design games are recommended to foster an open, equal, and collaborative culture. However, most studies focus on the West. East-Asian countries, notably China, face unique challenges due to cultural disparities and inertia. This paper explores design games in the Chinese context through a case study with traditional workshops, revealing participants' perspectives and the potential impact on cultural inertia.

A genomic investigation on the origins of the Korean brown planthopper, Nilaparvata lugens (Stål) (Hemiptera: Delphasidae)

AbstractNilaparvata lugens, the brown planthopper (BPH), is a serious pest species. BPHs cause significant damage to rice plants in Korea as well as other countries in East and Southeast Asia. As BPHs cannot survive winter in Korea, they annually migrate into Korea from foreign countries. The BPHs found in Korea are believed to originate from China, but most BPHs in China are also known to originate from Southeast Asia. To understand the origin of Korean BPHs, we conducted a genotyping‐by‐sequencing (GBS) study. We sampled BPHs from five locations in Korea and five countries in Southeast Asia and analyzed the GBS and sequencing results using various methods based on the f statistics and admixture graph analyses. We confirmed that the domestic BPHs shared a greater genetic drift than the BPHs from Southeast Asian populations over several years, implying that a continuous genetic substratum of Korea exists. This genetic substratum is genetically closer to BPHs from the southern part (Thailand and Cambodia) of Southeast Asia than to BPHs from the northern part (Bhutan, Myanmar and Laos) of Southeast Asia. In addition, direct gene flows from Southeast Asia seem possible, so Korea is considered a hotspot where diverse BPH populations mix. Therefore, the origin of Korean BPHs extends beyond China and as far as southern Southeast Asia. This result will help to understand and control the population dynamics of the Korean BPH population.

Generalized trust and attitudes toward immigrants in East Asia: A cross-national comparative study

Generalized trust has been widely discussed as a non-economic determinant influencing public attitudes toward immigrants among natives in Europe. However, associations between generalized trust and public opinions on immigrants remain underexplored in East Asia. This study investigates the association between generalized trust among natives and their attitudes toward immigrants, considering the interaction between generalized trust and country. Utilizing data from the 7th wave of the World Values Survey dataset for three East Asian countries—South Korea, China, and Japan—we fitted two mixed multilevel logistic regression models for two dependent variables in two scenarios: opposition to immigrants as neighbors, and prioritizing nationals in economic adversity. Results reveal that generalized trust was negatively related to natives' reluctance to accept immigrants as neighbors. However, the association was only marginally significant when examining support for in-group favoritism in economic adversity. The impact of generalized trust on these attitudes also exhibited variations by country. Notably, we found a negative association between generalized trust and opposing immigrants as neighbors in China and Japan, while this may not be the case for Korea.

Revisiting Traditional Chinese Medicine in Hong Kong during the Influenza Epidemics in the 1950s and 1960s.

This paper examines the supply and utilization of traditional Chinese medicine (TCM) in Hong Kong during the influenza epidemics of the 1950s and 1960s. Existing narratives of TCM in Hong Kong have predominantly framed with within the dichotomy of Western medicine "Xiyi" and Chinese medicine "Zhongyi," portraying TCM as marginalized and nearly wiped out by colonial power. Departing from this binary opposition, this study views TCM as an autonomous space that had never been subjugated by the colonial power which opted for minimal interventionist approach toward TCM. By adopting diachronic and synchronic perspectives on Hong Kong's unique environment shaped by its colonial history and the geopolitics of the Cold War in East Asia, particularly its relationships with "China," this research seeks to reassess the role and status of TCM in post-World War II Hong Kong. In Hong Kong, along with other countries in East Asia, traditional medicine has ceded its position as mainstream medicine to Western medicine. Faced with the crisis of "extinction," Chinese medical professionals, including medical practitioners and merchant groups, persistently sought solidarity and "self-renewal." In the 1950s and 1960s, the colonial authorities heavily relied on private entities, including charity hospitals and clinics; furthermore, there was a lack of provision of public healthcare and official prevention measures against the epidemic influenza. As such, it is not surprising that the Chinese utilized TCM, along with Western medicine, to contain the epidemics which brought about an explosive surge in the number of patients from novel influenza viruses. TCM was significantly consumed during these explosive outbreaks of influenza in 1957 and 1968. In making this argument, this paper firstly provides an overview of the associations of Chinese medical practitioners and merchants who were crucial to the development of TCM in Hong Kong. Secondly, it analyzes one level of active provision and consumption of Chinese medicine during the two flu epidemics, focusing on the medical practices of TCM practitioners in the 1957 epidemic. While recognizing the etiologic agent or agents of the disease as influenza viruses, the group of Chinese medical practitioners of the Chinese Medical Society in Hong Kong adopted the basic principles of traditional medicine regarding influenza, such as Shanghanlun and Wenbingxue, to distinguish the disease status among patients and prescribe medicine according to correct diagnoses, which were effective. Thirdly, this paper examines the level of folk culture among the people, who utilized famous prescriptions of Chinese herbal medicine and alimentotherapy, in addition to Chinese patent medicines imported from mainland China. In the context of regional commercial network, this section also demonstrates how Hong Kong served as a sole exporting port of medicinal materials (e.g., Chinese herbs) and Chinese patent medicines from the People's Republic of China to capitalist markets, including Hong Kong, under the socialist planned or controlled economy in the 1950s and 1960s. It was not only the efficacy of TCM in restoring immunity and alleviating symptoms of the human body, but also the voluntary efforts of these Chinese medical practitioners who sought to defend national medicine "Guoyi," positioning it as complementary and alternative medicine to scientific medicine. Additionally, merchants who imported and distributed Chinese medicinal materials and national "Guochan" Chinese patent medicine played a crucial role, as did the people who utilized Chinese medicine, all of which contributed to making TCM thrive in colonial Hong Kong.

The Global Impact of HIV: A Comprehensive Review

The Human Immunodeficiency Virus (HIV) has been a significant global health challenge since its discovery in the 1980s, leading to the devastating Acquired Immunodeficiency Syndrome (AIDS). Despite advancements in medical research and antiretroviral therapies, HIV/AIDS remains a pressing public health concern, particularly in resource-limited regions. This comprehensive review provides updated data and scientific insights on the global impact of HIV, shedding light on the current state of the epidemic and the challenges faced in combating it. The review highlights the resurgence of HIV cases in Eastern European countries, such as Ukraine, Estonia, and Latvia, with surprising increases in AIDS cases observed in East Asian countries. However, it is in sub-Saharan Africa that the burden of HIV remains most acute, with high prevalence rates and a significant number of affected individuals. The region requires continued attention and resources to address the complex challenges associated with HIV prevention, treatment, and care. The article delves into the classification and structure of HIV, emphasizing its belonging to the Lentivirinae subfamily, specifically HIV-1 and HIV-2. HIV-1, the predominant viral species globally, exhibits a distinct clinical latency phase, contributing to its persistence and infectivity. The high replication rate and genetic variability of HIV, driven by the error-prone reverse transcriptase enzyme, result in the emergence of diverse subtypes and strains across different regions. Furthermore, the article explores the structural components of HIV-1, including the envelope glycoproteins (gp120 and gp41), matrix protein, and various enzymes critical to the viral life cycle. Despite progress in medical research and access to antiretroviral therapies, HIV/AIDS continues to present challenges such as limited resources, drug resistance, and regional disparities.

中日“西厢故事”中才子形象的对比考察

The word “Gifted scholar” riginated from Chinese literature During the exchange of Chinese culture with East Asian countries, “Gifted scholar” was absorbed by Japan, which was influenced by Chinese culture, and became a synonym for the hero in Japanese romance novels. As an imitative work of the Chinese Yuan drama “The Romance of the West Chamber”, the Japanese Chinese-character novels “The Romance of Happy Couple ” has both similarities and differences with the Image of Gifted scholar in the Story of “The Romance of the West Chamber”. Based on text analysis, this paper will sort out the content about the image of the gifted scholar in the Chinese and Japanese “The Story of the West Chamber”, highlight the different aspects of the image of the gifted scholar in the two works, and focus on exploring the reasons for this difference. The Japanese writer Miki Aika was influenced by Chinese Confucian culture. The male protagonist in “The Romance of Happy Couple” inherited the image of talented scholar who combines talent, amorous feeling and appearance from “The Romance of the West Chamber”. On the other hand, due to the cultural characteristics of the Japanese nation and the development of the Meiji Restoration, the image of the gifted scholar in Japan's “The Story of the West Chamber” has changed again. By examining and comparing the image of the gifted scholar in Chinese and Japanese “The Story of the West Chamber”, this paper explains that although the external image of the hero in the <The Romance of Happy Couple> is similar to that of the Chinese gifted scholar, his inner core characteristics still contain Japan’s national character and contemporaneity.

First Report of 'Candidatus Phytoplasma asteris'-related Strain (16SrI group) Associated with Small Leaves, Leaf Yellowing, and Shoot Proliferation of Morning Glory (Ipomoea biflora) in Taiwan.

Ipomoea biflora L., commonly known as morning glory, is an herbaceous vine plant in the Convolvulaceae family and is widespread at low elevations in Taiwan and other East Asian countries. In September 2023, six I. biflora plants exhibiting small leaves, leaf yellowing, and shoot proliferation were observed in a vacant lot in Taiwan Agricultural Research Institute (TARI), Wufeng District, Taichung, Taiwan, representing 100% disease incidence in the area. All the symptomatic morning glory climbed onto Murraya paniculata L. (common jasmine orange) which however showed no similar symptoms. The total DNA (two samples for each plant) from leaf tissues of three symptomatic morning glory plants, two asymptomatic morning glory plants, and one asymptomatic common jasmine orange was isolated by the CTAB method (Fulton et al. 1995) and used for PCR with the universal primers, P1 (Deng and Hiruki 1991)/P7 (Schneider et al. 1995), to amplify a fragment containing partial 16S rDNA. Expected 1.8-kb bands were amplified from DNA extracted from all symptomatic plants, whereas no PCR product was detected from that of the asymptomatic I.biflora and M. paniculata plants. Six PCR products were cloned and sequenced in the Biotechnology Center DNA-sequencing facility at National Chung Hsing University, and one representative sequence was selected and deposited in GenBank. BLAST analysis revealed that the obtained 16S rDNA sequence (PP230905) shared 99.92% identity with the following phytoplasma strains: rapeseed phyllody phytoplasma (CP055264), plumbago auriculata leaf yellowing phytoplasma (MN239503), and aster yellows phytoplasma (MK992774), which all belong to the 16SrI subgroup. The query 16S rDNA sequence shares 99.84% identity with that of the 'Candidatus Phytoplasma asteris' reference strain (M30790), suggesting that the phytoplasma is a 'Ca. Phytoplasma asteris'-related strain. A virtual restriction fragment length polymorphism (RFLP) analysis was conducted using iPhyClassifier tool (Zhao et al. 2009), and the pattern derived from the 16S rDNA fragment of the I. biflora phytoplasma was identical (similarity coefficient 1.00) to the reference pattern of 16SrI, subgroup B (onion yellows phytoplasma OY-M; AP006628). Six total DNA samples from symptomatic plants were used as templates to amplify 842 bp secA sequences with SecAfor1 and SecArev3 primers (Hodgetts et al. 2008), and one representative sequence was deposited in GenBank. The partial secA sequence (PP263636) showed 98.22% identity with that of Trema levigatum witches'-broom phytoplasma (MW032212) that also belongs to the 16SrI group (Wan et al. 2021). Phylogenetic analysis of both 16S rDNA and secA confirmed I. biflora phytoplasma as 16SrI, subgroup B. Taken together, we concluded that the morning glory phytoplasma in this study was a 'Ca. Phytoplasma asteris'-related strain belonging to the 16SrI group. To the best of our knowledge, this is the first report of a phytoplasma-infected I. biflora in Taiwan, suggesting morning glory as a new natural host of 16SrI phytoplasmas, alongside other plants like roselle and citrus (Tseng et al. 2014; Feng et al. 2015).

A study on economic cooperation in the EU and East Asia: can Franco-German cooperation be a model for Japan and Korea?

The economic integration has been the most important agenda since the Second World War particularly in Europe because many European nations were heavily destroyed and ruined. After the severe destruction, European political leaders started to rethink how to restore Europe economically and politically in order to establish a long-term peace in Europe. The two major countries, France and Germany, initiated this based on reconciliation processes and signed on the Elysee Treaty that is legally binding and known as the de jour approach. Unfortunately, East Asian countries, Japan and South Korea took a different path, without reconciliation processes, based on the de facto approach only for economic cooperation. As a result, it is not solid yet, but contains fragile risks for the two countries to cooperate in a sustainable way. This paper investigates how and why Franco-German tandem has played core roles in the EU integration. Furthermore, it argues what are successful factors for Franco-German cooperation. Last, but not least, it analyzes whether the Franco-German model can be adapted for the Japan-Korea economic cooperation or not. Received: 31 January 2024Accepted: 05 March 2024

Consumer Satisfaction and Perception Towards Green Tea

Green tea is a type of tea that is made from Camellia sinensis leaves and buds that have not undergone the same withering and oxidation process used to make oolong teas and black teas.[1] Green tea originated in China, but its production and manufacture has spread to other countries in East Asia. Several varieties of green tea exist, which differ substantially based on the variety of C. sinensis used, growing conditions, horticultural methods, production processing, and time of harvest. Although there has been considerable research on the possible health effects of consuming green tea regularly, there is little evidence that drinking green tea has any effects on health

A Research on the Origins of Ritual Theatre in Eastern Asia: The Associative Development of Chinese Nuo Theatre and Japanese Noh Theatre

As a region with a significant agricultural industry, the ritual theatre of East Asia played an important role in the early drama of its origins. In addition, the trajectory of the early agricultural and religious cultural interactions in East Asian countries was decisive in shaping their national cultural roots, so exploring the different developments of ritual theatre among different countries on the basis of the history of early cultural interactions can help to provide a more explicit understanding of the cultural development of ritual theatre in East Asia. This research explores the trajectories of Nuo theatre in China and Noh theatre in Japan, broadly in terms of both agriculture and religion, summarises the similarities and differences between the developmental routes of Nuo and Noh theatre, and analyses the causes of the contemporary phenomenon of Nuo and Noh theatre moving along different developmental routes.
