After adopting the Paris Agreement, many countries (including developing countries) have started to develop targets aimed at achieving net-zero emissions to realize a "decarbonized society" in response to the 1.5 °C target. Effective plans and actions need to be urgently developed on how to achieve the ambitious targets associated with these targets, but not many countries have developed long-term strategies to achieve net zero emissions. The Asia–Pacific Integrated Model (AIM) team has been working with researchers and policymakers in Japan and other Asian countries to develop a long-term strategy toward a decarbonized society. Asia is a region with diverse countries, and there are many different pathways to achieve decarbonized societies. This paper presents the process of developing a long-term strategy for several Asian countries based on our experiences to date and discusses challenges and solutions, including how to use the AIM models in the policy-making process.

This paper demonstrates and assesses the capability of the advanced three-dimensional (3-D) ionosphere tomography technique, during severe conditions. The study area is northeast Asia and quasi-Japan-centred. Reconstructions are based on total electron content data from a dense ground-based global navigation satellite system receiver network and parameters from operational ionosondes. We used observations from ionosondes, Swarm satellites and radio occultation (RO) to assess the 3-D picture. Specifically, we focus on St. Patrick's day geomagnetic storm (17–19 March 2015), the most intense in solar cycle 24. During this event, the energy ingested into the ionosphere resulted in Dst and Kp and reaching values ~ − 223 nT and 8, respectively, and the region of interest, the East Asian sector, was characterized by a ~ 60% reduction in electron densities. Results show that the reconstructed densities follow the physical dynamics previously discussed in earlier publications about storm events. Moreover, even when ionosonde data were not available, the technique could still provide a consistent picture of the ionosphere vertical structure. Furthermore, analyses show that there is a profound agreement between the RO profiles/in-situ densities and the reconstructions. Therefore, the technique is a potential candidate for applications that are sensitive to ionospheric corrections. [ABSTRACT FROM AUTHOR]

This paper is based on a localized case study of teaching Sino-Japanese energy issues in the area studies setting of Japanese studies through a historical perspective. It is based on the author's four semesters of teaching at Chinese University of Hong Kong, the complexities of which are increased by the 11 March 2011 Great East Japan Earthquake and the resulting discussions of energy issues in Northeast Asia. Five sub-topics related to energy are discussed here: energy transitions; history of energy fuel use in Northeast Asia; the scarcity of fossil fuels in the region; competition and cooperation for energy resources; and the potential and possibility of non-fossil fuel replacement resources. These five sub-topics are collectively discussed and contextualized in the post-311 or post-Great East Japan Earthquake scenario. The methodology used in analyzing the content approach to covering these topics and making them accessible to students fall into three main areas: the use of historiography to cover the major arguments, concepts and scholarly arguments/schools of thought in teaching these sub-topics; techniques in constructing historical overviews to make these topics accessible to area studies students and constructing literature reviews to stimulate student discussions on post-311 energy scenarios in Northeast Asia within the contextualized of the globalized energy industry and relations. Limitations of these approaches will be discussed through observation techniques. Textual analysis of textbooks covering these topics will also be analyzed based on the author's bibliographic use in constructing the course materials for the above subject areas. Finally, some concluding trends, remarks and observations as well as implications of the above teaching experience are covered in the concluding section. [ABSTRACT FROM AUTHOR]

There has been an increasing demand for detailed and accurate landslide maps and inventories in disaster-prone areas of subtropical and temperate zones, particularly in Asia as they can mitigate the impacts of landslides on social infrastructure and economic losses. Hence, in this study, models using automatically constructed high-performing convolutional neural network (CNN) architectures for landslide detection were applied and their outcomes were compared for landslide susceptibility mapping at the Kii peninsula, Japan. First, a total of 38 landslide and 63 non-landslide points were identified and divided into 70% and 30% of training and validation datasets, respectively. Eight landslide influence factors were used: slope angle, eigenvalue ratio, curvature, underground openness, overground openness, topographic witness index, wavelet, and elevation. These factors were selected using a 1-m DEM, which is easy to acquire and process data. Experimental results of model evaluation using receiver operating characteristics (ROC), area under the curve (AUC), and accuracy showed that the optimal models (ROC = 96.0%, accuracy = 88.7%) were more accurate than initial models (ROC = 91.1%, accuracy = 80.7%) in predicting landslides spatially. Furthermore, the landslide susceptibility mapping is consistent with the trends in the distribution of gentle slopes and knick lines unique to the study area and can be used as a powerful method for predicting landslides in future.

We examined satisfaction and perceived challenges with antiretroviral therapy (ART) among people living with HIV (PLHIV) in Japan vs three other Asian countries (China, Taiwan, South Korea), and 21 non-Asian countries, using data from the 2019 Positive Perspectives Study (pooled sample size from all 25 countries = 2389). Participants in other Asian countries were more likely than those in Japan to report they missed ART ≥ 1 time in the past month because they were depressed/overwhelmed (57.4%[89/155] vs 32.0%[24/75]), had privacy concerns (56.8%[88/155] vs 30.7%[23/75]), were concerned about the potential long-term negative impacts of ART (46.5%[72/155] vs 26.7%[20/75]), or just wanted to forget about HIV (45.8%[71/155] vs 22.7%[17/75]). ART satisfaction however did not differ significantly between surveyed PLHIV in Japan (54.7%[41/75]) vs those in other Asian countries (47.7%[74/155]). The percentage who felt that daily ART dosing limited their lives was 36.0%[27/75] among participants from Japan, 48.4%[75/155] among participants from other Asian countries, and 27.3%[589/2159] among those from non-Asian countries. Within a structural equation model using pooled data from all 25 countries, positive correlations were seen between ART satisfaction and "provider engagement" (β = 0.35), high perceived control over ART dosing schedule (β = 0.28), and the belief that ART prevents HIV transmission (β = 0.16). Conversely, negative correlations were seen between ART satisfaction and experience of ART side-effects (β = − 0.24), high "ART anxiety" (β = − 0.20); and being on multi-tablet regimens (β = − 0.13). Those ART-satisfied reported higher self-rated health and greater ART adherence. These findings underscore the need for patient-centered care to enhance treatment satisfaction and improve ART adherence. [ABSTRACT FROM AUTHOR]

Background: The mortality and risk factors of severe disease and death due to arterial and venous thromboembolism (ATE and VTE, respectively) in patients with inflammatory bowel disease (IBD) remain unclear, especially in Asia. Aims: This study aimed to reveal the mortality and risk factors of TE in IBD patients in Japan. Methods: In the primary surveillance, responses to questionnaires regarding the number of cases of severe TE and TE-associated death in IBD patients in a span of over the past 10 years were obtained from 32 institutions in Japan. In the secondary surveillance, detailed data about IBD patients with TE were collected. The characteristics, laboratory data, therapy status, and situation at the time of TE development were retrospectively collected, and the data were compared between the patients with and without severe TE and TE-associated death. Results: The incidence of TE was 1.89% among 31,940 IBD patients. The frequencies of severe TE and TE-associated mortality were 10.7% and 1.0% among the total IBD and TE with IBD patients, respectively. The only risk factor for severe ATE and ATE-associated death was ischemic heart disease. The independent risk factors for severe VTE and VTE-associated death were age (≤ 45 years old), the site of VTE, and disease severity, with anti-TNF therapy as a potential negative risk factor. Patients with severe VTE had a high risk of developing persistent VTE and sequelae. Conclusion: Unlike ATE, the incidence of VTE was comparable in Asian and Western countries. Therapeutic and prophylactic strategies for managing IBD-associated TE in Asia are urgently needed. [ABSTRACT FROM AUTHOR]

The author reflects on the state of thermal spraying in Asia. He mentions that Korea has more than forty thermal spraying companies and is engaged in research. He comments that with China's economic expansion, its thermal spray industry is small but has a lot of potential for growth. He also discusses thermal spraying in Japan.

The article cites a U.S. report that states that Asian nations are catching up with Europe and the United States in terms of scientific output. According to the report, in 2004, countries from the Asia Pacific region including China, South Korea, Taiwan, Japan, Singapore and India produced 25 percent of the world's research papers. By comparison, Europe produced 38 percent of the world's scientific papers, and the United States produced 33 percent. Within Asia, China, South Korea, Singapore and Taiwan grew the most. In China, some institutions even pay researchers extra for publications in indexed journals, especially ones that carry widely cited articles.

Large, extensively diversified pyramidal business groups of listed firms dominate the histories of developed economies and the economies of developing economies. While such groups (called zaibatsu in Japan) are thought to have provided coordination for big push growth successfully in pre-second-world-war Japan after a state-run big push failed, it is still being debated whether such a pyramidal business group driven big push coordination exists in developing countries elsewhere in Asia. We hypothesize that pyramidal business groups can be private-sector mechanisms for coordinating big push growth, provided that first, competition between rival groups induces a sufficiently high level of coordination efficiency, and second, conditions exist for maintaining economic openness and basic infrastructure and legal institutions. Another condition that must be satisfied for a country to sustain economic growth after its big push phase is complete is a timely demise of business groups. Where these criteria are not met, growth stalls and the few pyramidal business groups become too powerful to dislodge. [ABSTRACT FROM AUTHOR]

This article explores the economic calculations behind the recent initiatives for the Free Trade Agreement (FTA) between the Governments of China, Japan and South Korea (CJK) and clarifies the implications for future regional economic integration. First, the proposed trilateral FTA signifies an advancement of China-centered regional economic integration. Regional economic integration led by China may also increase its political clout at the global stage. Second, the Governments of South Korea and Japan seek greater involvement in China's huge domestic market, but the former is concerned that a trilateral FTA will worsen its trade deficit with Japan, and the latter is afraid of losing its market shares in China and America to its Korean rival. Japan, therefore, seeks membership of both the CJK FTA and the Trans-Pacific Partnership (TPP). Third, China and the US' active involvement in regional economic integration will push the three countries to go forward towards greater economic cooperation. However, it will take longer for China-led Regional Comprehensive Economic Partnership (RCEP) and America-led TPP to bear fruit because of the large number of countries involved. Therefore, the conclusion of CJK FTA will be an important boost for the further progress of both RCEP and TPP. It will also be an important stabiliser for the trilateral political relations in the future. [ABSTRACT FROM AUTHOR]

The Japanese government faces many competing challenges as it seeks to balance its multilateral and bilateral relationships within and beyond the region: whilst addressing its rapidly changing contentious domestic politics, there is pressure for it to realign relations with the USA, manage the rise of China, strengthen links with its region and continue to deal with its lingering historical legacy. All of these demands are now set against the backdrop of a so-called 'lost decade' of economic woes and global economic recession. This article demonstrates how the Japanese government is apparently adopting a de facto multilevel foreign policy, attempting to engage in a range of bilateral and collective initiatives simultaneously and to assume a regional leadership role whilst having to manage difficult bilateral relations, notably with the USA and China.

A study was conducted to understand the floral characteristics and diversity of benthic diatoms (Bacillariophyceae) at Nanaura mudflat (E 130° 10′, N 33° 04′) on the coast of the Ariake Sea, Japan. A literature review was also performed to better understand the biogeography of the marine benthic diatoms of Northeast Asia. Light microscopic and scanning electron microscopic observations revealed a total of 90 Nanaura taxa. All species were listed along with their dimensions, microstructural densities, and if necessary, their ultrastructures. Dominant species found were Navicula sp. 1 (12.6%), Paralia sulcata (10.3%), Tryblionella granulata (8.8%), Navicula flantanica (6.8%), Gyrosigma wansbeckii (5.8%) and Cyclotella striata (5.6%). The abundance of the six species collectively accounted for ca. 50% of the total. As for salinity requirements, marine and brackish-marine forms were dominant, while brackish and freshwater species were also observed. Species composition of diatom flora at the study site showed relatively close similarity with those of mudflat (e.g., Isahaya Bay) and brackish lagoon (Matsukawaura Lagoon) in Japan, but were also similar to those of other localities, e.g. at Songdo mudflat in Korea and Fujian coast in China. Thirteen reports of the benthic diatoms from Northeast Asia were selected for comparison based on diatom habitats and data quality. Twentyone species of Nanaura diatoms, including Cymatotheca weissflogii and Tryblioptychus cocconeiformis, whose reports are rare in the Western Hemisphere and Europe, occurred across Japan, Korea, and China, and represent common benthic diatoms in Northeast Asia.

Japan was Asia's leading generator of international tourism in the 1980s and 1990s. Japanese tourists make up over 30% of all international tourists to Taiwan and they have been the highest ranking tourist source market since the early stages of the island's tourism development in the 1970s. However, the Severe Acute Respiratory Syndrome (SARS) outbreak in 2003, the most catastrophic disaster in the past 100 years in Taiwan, had a huge impact on Japanese inbound tourism to the island. The purpose of this study is to evaluate how Japanese inbound arrivals have been affected by the SARS outbreak. A SARIMA with intervention model is used to assess the impact of the epidemic on inbound tourism from Japan to Taiwan in the aftermath of the SARS outbreak. The empirical results indicated that inbound tourism from Japan was devastated by the crisis, particularly during the first 5 months after the SARS outbreak. This study provides some helpful insight for the tourism industry to respond to the impact of exogenous shock. [ABSTRACT FROM AUTHOR]

Institutional regionalization has come very late to East Asia compared with Europe, but its pace has dramatically increased since the mid-1990s. Many agreements, including bilateral ones such as those signed between Japan and Singapore, or pluri-lateral ones such as those between ASEAN countries, cover an ever increasing number of countries of the East Asian region, including Japan, India, and China. We first analyze Asian integration as a de facto, spontaneous, development of trade. Trade specialization in Asia has often been described as guided by the different levels of development of the countries participating in the regional integration. It constitutes a vertical division of labor between poor countries exporting natural resources and/or labor-intensive products to developed countries exporting machinery, sophisticated parts and components, and high-tech products. This trade structure is radically different from the European horizontal division of labor (exchange of different varieties of similar goods). Then we look at the micro-economic level how Japanese firms tend to integrate Asia into their international network, with Japanese partners being used as relays for Japanese export of semi-manufactured products. Last we present a simulation with the MIRAGE model of a scenario of general regionalization in which all the regions of the world develop preferential treatment for neighboring countries. These agreements are limited to industrial products with particular attention to the automotive sector. The main results are that Asia is the main winner in such a scenario, and within Asia it is Japan and Korea that will be the main winners. In fact, because developing Asia is one of the most protected regions of the world, the impact of liberalization is also the highest. Second, Japan and Korea are best placed to profit from these regional agreements, because other developed countries are excluded from the market of developing Asia. They also have superiority in manufacturing goods whereas countries like China might have problems upscaling their industrial production. Nevertheless our model did not take into account the voluntary pace of development chosen by China and that she will use her powerful state system to avoid being locked into low-tech, low-value-added products.

Outbreaks of highly pathogenic avian influenza (HPAI) have been occurring in domestic poultry in Asia since 1996. In the beginning of 2004, HPAI outbreaks were caused by H5N1 virus in two farms and a group of pet chickens in different areas of Japan. In the present study, the pathogenicity of A/chicken/Yamaguchi/7/04 (H5N1), which had been isolated from a dead chicken during the first outbreak in Japan, was assessed in chickens, quails, budgerigars, ducklings, mice, and miniature pigs by experimental infection. The virus was highly pathogenic to all the birds tested. Mice were susceptible to infection with a low mortality rate and miniature pigs were resistant to infection with the virus.

The Pacific plate converges with northeastern Eurasia at a rate of 8-9 m per century along the Kamchatka, Kuril and Japan trenches[SUP1]. Along the southern Kuril trench, which faces the Japanese island of Hokkaido, this fast subduction has recurrently generated earthquakes with magnitudes of up to ∼8 over the past two centuries[SUP2-6]. These historical events, on rupture segments 100-200 km long, have been considered characteristic of Hokkai-do's plate-boundary earthquakes[SUP7,8]. But here we use deposits of prehistoric tsunamis to infer the infrequent occurrence of larger earthquakes generated from longer ruptures. Many of these tsunami deposits form sheets of sand that extend kilometres inland from the deposits of historical tsunamis. Stratigraphic series of extensive sand sheets, intercalated with dated volcanic-ash layers, show that such unusually large tsunamis occurred about every 500 years on average over the past 2,000-7,000 years, most recently ∼350 years ago. Numerical simulations of these tsunamis are best explained by earthquakes that individually rupture multiple segments along the southern Kuril trench. We infer that such multi-segment earthquakes persistently recur among a larger number of single-segment events. [ABSTRACT FROM AUTHOR]

The symposium focused on the bio-logging research including telemetry, tracking, tagging, and remote monitoring of aquatic and terrestrial animals initiated by Chinese and Japanese researchers. The symposium's program is divided into 4 sessions and several advances in bio-logging science and technology in Asia were presented.

Unlabelled: Tumour necrosis factor receptor-associated periodic syndrome (TRAPS) is a dominantly inherited disorder characterised by recurrent episodes of sustained fever. Here we report a case of TRAPS with a novel TNFRSF1A mutation, C70S, in a Japanese family. The mutation disrupts one of the three disulphide bonds in cysteine-rich domain 2 of TNF receptor 1, similar to the reported mutations of the same cysteine residue (C70R, C70Y). This is the first confirmed case of TRAPS in an eastern Asian population. The patient's asymptomatic sister as well as their mother with mild symptoms had the same mutation.Conclusion: Although tumour necrosis factor receptor-associated periodic syndrome has been reported mainly in families of northern European ancestry, our case suggests the need to include it in the differential diagnosis of patients with recurrent fever even in ethnic groups in which no case has been documented.

The article reports that Cryptotympana facialis, a black cicada insect, threatens citizens and fiber-optic system in western Japan and other subtropical regions of eastern Asia. A survey conducted by Shigehiko Shiyake, curator of the Osaka Museum of Natural History, and Eiji Numata, a biologist at Osaka University, shows that the insect population increases every four years with nearly 2.5 times as many in 2006. Study also shows that these insects are mistakenly layed their eggs on fiber-optic cables as withered branches, however, telephone companies have responded by creating new cables with added protective plastic layer to the cable.
