Cool and wet weather conditions hit northern Central Asia, East Asia and central North America during the 2009 summer in concert with a strong jet stream and a prominent meandering upper-level circulation in the Northern Hemisphere mid-latitudes despite the fact that the year 2009 is the fifth warmest year globally in the modern record. It is found that the conspicuous atmospheric variability in the entire Northern Hemisphere mid-latitudes during the summer of 2009 was caused by a combination of teleconnections associated with significant tropical thermal forcings, strong polar forcing, and interaction between high-frequency weather events and climate anomalies. The strong negative circumglobal teleconnection pattern associated with the deficient Indian summer monsoon rainfall and developing El Niño condition was the major contributor to the cool and wet summer in June. On the other hand, the July weather conditions were attributable to the high-latitude impact of the unprecedented negative Arctic Oscillation, together with the Rossby wave response to the subtropical heating generated by convective activities over the Western North Pacific summer monsoon region. It is also noted that enhanced storm track activity and frequent cold surges from high-latitudes may have played a role in the cool and wet summer over the regions of interest. (letter)

Surface ozone is a greenhouse gas and pollutant detrimental to human health and crop and ecosystem productivity. The Tropospheric Ozone Assessment Report (TOAR) is designed to provide the research community with an up-to-date observation-based overview of tropospheric ozone's global distribution and trends. The TOAR Surface Ozone Database contains ozone metrics at thousands of monitoring sites around the world, densely clustered across mid-latitude North America, western Europe and East Asia. Calculating regional ozone trends across these locations is challenging due to the uneven spacing of the monitoring sites across urban and rural areas. To meet this challenge we conducted a spatial and temporal trend analysis of several TOAR ozone metrics across these three regions for summertime (April-September) 2000-2014, using the generalized additive mixed model (GAMM). Our analysis indicates that East Asia has the greatest human and plant exposure to ozone pollution among investigating regions, with increasing ozone levels through 2014. The results also show that ozone mixing ratios continue to decline significantly over eastern North America and Europe, however, there is less evidence for decreases of daytime average ozone at urban sites. The present-day spatial coverage of ozone monitors in East Asia (South Korea and Japan) and eastern North America is adequate for estimating regional trends by simply taking the average of the individual trends at each site. However the European network is more sparsely populated across its northern and eastern regions and therefore a simple average of the individual trends at each site does not yield an accurate regional trend. This analysis demonstrates that the GAMM technique can be used to assess the regional representativeness of existing monitoring networks, indicating those networks for which a regional trend can be obtained by simply averaging the trends of all individual sites and those networks that require a more

Full Text Available Nephila clavata L Koch, known as the Joro spider and native to East Asia (Japan, China, Korea, and Taiwan, is newly reported from North America. Specimens from several locations in northeast Georgia were collected from around residential properties in Barrow, Jackson, and Madison counties in late October and early November 2014. These are the first confirmed records of the species in the New World. Our collections, along with confirmed images provided by private citizens, suggest that the Joro spider is established in northeast Georgia. Genomic sequence data for the COI gene obtained from two specimens conforms to published sequences for N. clavata, providing additional confirmation of species identity. Known collection records are listed and mapped using geocoding. Our observations are summarized along with published background information on biology in Asia and we hypothesize on the invasion history and mode of introduction into North America. Recognition features are given and photographic images of the male and female are provided to aid in their differentiation from the one native species of the genus (Nephila clavipes in North America.

Multiple sclerosis (MS) is one of the most common chronic immune-mediated diseases of the human central nervous system and an important cause of non-traumatic neurologic disability among young population in several countries. Recent reports from East Asia, South East Asia and South Asia have proposed a low to moderate prevalence of MS in these countries. A literature review search was carried out in December 2014 in Medline, Embase, Scopus and Cochrane library to recover original population-based studies on MS epidemiology in East Asia, South East Asia and South Asia countries published between January 1, 1950 and December 30, 2014. We intended search strategies using the key words: multiple sclerosis, prevalence, incidence and epidemiology. Based on our inclusion criteria, 68 epidemiologic studies were included in this systematic review. The most extensively used diagnostic criteria in the studies were McDonald's criteria. Most studies were performed in a multi-center hospital setting. The female to male ratio varied and ranged from 0.7 in India to 9.0 in China. The mean age at disease onset ranged from the lowest age of 25.3 in Iran to the highest age of 46.4 in China. MS prevalence ranged from 0.77 in 100,000 populations in Hong Kong (1999) to 85.80 in 100,000 in Iran (2013). Advances in MS registries around the globe allow nationwide population-based studies and will allow worldly comparisons between the prevalence and incidence in different regions that are provided to monitor estimation. © 2016 S.

Recent analyses of world NGL trade indicate that important changes in LPG supply and demand are under way in Asia and North America. LPG markets in the 1990s reflect a rapidly shifting balance between East-of-Suez and West-of-Suez markets. This shift has increased concern about availability of future LPG supplies for Asia. The paper discusses world developments, East versus West of Suez, end uses and supplies in Asia, Canadian ethane, propane, butane, and natural gasoline, Mexican ethane, LPG, and natural gasoline, US ethane, propane, butanes, and iso-C 4 and C 5

Further development of the North-East Asian energy system is at a crossroads due to severe limitations of the current conventional energy based system. For North-East Asia it is proposed that the excellent solar and wind resources of the Gobi desert could enable the transformation towards a 100% renewable energy system. An hourly resolved model describes an energy system for North-East Asia, subdivided into 14 regions interconnected by high voltage direct current (HVDC) transmission grids. Simulations are made for highly centralized, decentralized and country-wide grids scenarios. The results for total system levelized cost of electricity (LCOE) are 0.065 and 0.081 €/(kW·h) for the centralized and decentralized approaches for 2030 assumptions. The presented results for 100% renewable resources-based energy systems are lower in LCOE by about 30-40% than recent findings in Europe for conventional alternatives. This research clearly indicates that a 100% renewable resources-based energy system is THE real policy option.

Security environment and nuclear proliferation problems in East Asia

International Nuclear Information System (INIS)

Suh, Mark Byung-Moon

East Asia was and still is divided into two conflicting ideological blocs. Because of the Cold War between these two blocs, two international wars were fought and tensions limited interactions among these countries. Despite these political constraints, in recent years East Asia has become economically one of the most dynamic regions in the world. Now that the Cold War between the USA and the Soviet Union is over, the danger of global nuclear war involving the nuclear powers in the region has been practically eliminated. Nonetheless, security has become more complex and demands a whole new set of arrangements. Yet the region lacks a cohesive multilateral framework for conflict resolution, and only recently have various attempts been made to create a political forum for the countries in the region. The problem and the danger of nuclear proliferation was vividly shown by the North Korean nuclear crisis in the last years. This issue not only halted the fragile process of normalization between the two Koreas, which started in 1988, but almost led to a new military conflict on the peninsula involving the two Koreas and the USA. It was defused only after the USA proved willing to offer security guarantees to North Korea. This problem still needs to be resolved, and it demands radical changes in the overall political environment in the region. Needless to say, proliferation in North Korea would have entailed grave consequences for the security of the region as well as for the international non-proliferation regime. This paper reviews the issue of nuclear proliferation of the three non-nuclear states in the region and deals with the non-introduction of nuclear weapons in the region by the nuclear powers. It discusses the prospects for a nuclear-weapon-free zone on the Korean peninsula. Perspectives of a sustainable security environment in East Asia will be briefly discussed

Impact of the Dominant Large-scale Teleconnections on Winter Temperature Variability over East Asia

2013-01-01

Monthly mean geopotential height for the past 33 DJF seasons archived in Modern Era Retrospective analysis for Research and Applications reanalysis is decomposed into the large-scale teleconnection patterns to explain their impacts on winter temperature variability over East Asia. Following Arctic Oscillation (AO) that explains the largest variance, East Atlantic/West Russia (EA/WR), West Pacific (WP) and El Nino-Southern Oscillation (ENSO) are identified as the first four leading modes that significantly explain East Asian winter temperature variation. While the northern part of East Asia north of 50N is prevailed by AO and EA/WR impacts, temperature in the midlatitudes (30N-50N), which include Mongolia, northeastern China, Shandong area, Korea, and Japan, is influenced by combined effect of the four leading teleconnections. ENSO impact on average over 33 winters is relatively weaker than the impact of the other three teleconnections. WP impact, which has received less attention than ENSO in earlier studies, characterizes winter temperatures over Korea, Japan, and central to southern China region south of 30N mainly by advective process from the Pacific. Upper level wave activity fluxes reveal that, for the AO case, the height and circulation anomalies affecting midlatitude East Asian winter temperature is mainly located at higher latitudes north of East Asia. Distribution of the fluxes also explains that the stationary wave train associated with EA/WR propagates southeastward from the western Russia, affecting the East Asian winter temperature. Investigation on the impact of each teleconnection for the selected years reveals that the most dominant teleconnection over East Asia is not the same at all years, indicating a great deal of interannual variability. Comparison in temperature anomaly distributions between observation and temperature anomaly constructed using the combined effect of four leading teleconnections clearly show a reasonable consistency between

The present study revealed that a climate regime shift occurred during the 1988-1991 period involving changes in tropical cyclone (TC) intensity (central pressure, maximum sustained wind speed) during the summer near 30°N in East Asia. Climatologically, TC intensity at 110°-125°E near 30°N (over Mainland China) is the weakest at that latitude while the strongest is found at 125°-130°E (over Korea). The TC intensity during the 1991-2015 (91-15) period had strengthened significantly compared to that of the 1965-1988 (65-88) period. The strengthening was due to a significantly lower frequency of TCs that passed through Mainland China during the 91-15 period. This lower frequency of was due to anomalous northeasterlies blown from the anomalous anticyclonic circulation located over continental East Asia and that had strengthened along the coast. Instead, TCs mainly followed a path from eastern regions in the subtropical western North Pacific to Korea and Japan via the East China Sea due to anomalous cyclonic circulations that had strengthened in the western North Pacific. In addition, low vertical wind shear had formed along the mid-latitude region in East Asia and along the main TC track in the 91-15 period, and most regions in the western North Pacific experienced a higher sea surface temperature state during the 91-15 period than in the previous period, indicating that a favorable environment had formed to maintain strong intensities of TCs at the mid-latitudes. The characteristics of TCs at the lower latitudes caused a strong TC intensity at the time of landfall in Korea and a gradual shifting trend of landing location from the western to southern coast in recent years.

A useful sub-seasonal forecast is of great societal and economical value in the highly populated East Asian region, especially during boreal summer when frequent extreme events such as heat waves and persistent heavy rainfalls occur. Despite recent interest and development in sub-seasonal prediction, it is still unclear how skillful dynamical forecasting systems are in East Asia beyond 2 weeks. In this study we evaluate the sub-seasonal prediction over East Asia during boreal summer in the operational monthly forecasting system of Environment and Climate Change Canada (ECCC).Results show that the climatological intra-seasonal oscillation (CISO) of East Asian summer monsoonis reasonably well captured. Statistically significant forecast skill of 2-meter air temperature (T2m) is achieved for all lead times up to week 4 (days 26-32) over East China and Northeast Asia, which is consistent with the skill in 500 hPa geopotential height (Z500). Significant forecast skill of precipitation, however, is limited to the week of days 5-11. Possible sources of predictability on the sub-seasonal time scale are analyzed. The weekly mean T2m anomaly over East China is found to be linked to an eastward propagating extratropical Rossby wave from the North Atlantic across Europe to East Asia. The Madden-Julian Oscillation (MJO) and El Nino-Southern Oscillation (ENSO) are also likely to influence the forecast skill of T2m at the sub-seasonal timescale over East Asia.

The effect of future climate change on surface ozone over North America, Europe, and East Asia is evaluated using present-day (2000s) and future (2100s) hourly surface ozone simulated by four global models. Future climate follows RCP8.5, while methane and anthropogenic ozone precursors are fixed at year-2000 levels. Climate change shifts the seasonal surface ozone peak to earlier in the year and increases the amplitude of the annual cycle. Increases in mean summertime and high-percentile ozone are generally found in polluted environments, while decreases are found in clean environments. We propose climate change augments the efficiency of precursor emissions to generate surface ozone in polluted regions, thus reducing precursor export to neighboring downwind locations. Even with constant biogenic emissions, climate change causes the largest ozone increases at high percentiles. In most cases, air quality extreme episodes become larger and contain higher ozone levels relative to the rest of the distribution.

Redefining Human Security for Vulnerable Migrants in East Asia

Jiyoung Song

2015-01-01

Full Text Available This article proposes human security as an analytical framework to understand the current trends of irregular migration (both forced and unauthorised in East Asia and revisits the seven pillars of human security defined in the 1994 Human Development Report by the United Nations Development Programme (UNDP. It explains how the concepts of human security are parallel to those prescribed in international human rights conventions but different in terms of the attitude towards states. Human security does not directly challenge state authority and adds a sense of urgency and moral authority that requires extra-legal measures by the states. The author argues that human security is the securitisation of human rights and is a better framework and policy discourse than human rights to engage with state and non-state actors, especially in East Asia where political leaders are more receptive to the former idea. The study draws examples from stateless Rohingyas, undocumented sex workers in Thailand and Singapore, trafficked brides from Vietnam and Cambodia, and smuggled North Korean refugees in China to demonstrate the nexus between human security and irregular migration.

Molecular anthropological studies of the populations in and around East Asia have resulted in the discovery that most of the Y-chromosome lineages of East Asians came from Southeast Asia. However, very few Southeast Asian populations had been investigated, and therefore, little was known about the purported migrations from Southeast Asia into East Asia and their roles in shaping the genetic structure of East Asian populations. Here, we present the Y-chromosome data from 1,652 individuals belonging to 47 Mon-Khmer (MK) and Hmong-Mien (HM) speaking populations that are distributed primarily across Southeast Asia and extend into East Asia. Haplogroup O3a3b-M7, which appears mainly in MK and HM, indicates a strong tie between the two groups. The short tandem repeat network of O3a3b-M7 displayed a hierarchical expansion structure (annual ring shape), with MK haplotypes being located at the original point, and the HM and the Tibeto-Burman haplotypes distributed further away from core of the network. Moreover, the East Asian dominant haplogroup O3a3c1-M117 shows a network structure similar to that of O3a3b-M7. These patterns indicate an early unidirectional diffusion from Southeast Asia into East Asia, which might have resulted from the genetic drift of East Asian ancestors carrying these two haplogroups through many small bottle-necks formed by the complicated landscape between Southeast Asia and East Asia. The ages of O3a3b-M7 and O3a3c1-M117 were estimated to be approximately 19 thousand years, followed by the emergence of the ancestors of HM lineages out of MK and the unidirectional northward migrations into East Asia.

Full Text Available The article focuses on major dimensions, achievements, challenges and prospects of relations between Russia and East Asia. Strategic importance of the region is shaped by East Asia's increasing role in world politics and economy as well as by its appeal for Russia's modernization agenda. Russia's great power status rests upon the effectiveness of its East Asian policy and development model of Siberia and the Russian Far East. Russia's positions in East Asia have improved substantially over the 2000s. However, its involvement in regional economic interaction is still insignificant and Russia cannot be regarded as a full-fledged regional player in this domain. Russian-Chinese strategic partnership has been the axis of Russia's East Asian foreign policy, though overdependence on China threatens Russia's independent policy in the region and encourages Russia to search for ways to diversify its ties. Russia's national interests reside in multivector policy, aimed at developing substantive relations not only with China but also with Japan, South Korea, ASEAN (Vietnam in the first place and India along with Russia's involvement in the resolution of Korean nuclear crisis. The rise of China and the US counter-offensive have resulted in a changing strategic environment in East Asia. A need for balancing between the US and China has brought about ASEAN countries' desire to welcome Russia as a "balancer" or an "honest player" in the region. It corresponds with Russia's course on playing a greater role in regional cooperation and integration. Russia's improving ties in political, economic, energy and security dimensions have the potential to contribute to the stability of the emerging polycentric regional order in East Asia and development of Russia's regions of Siberia and the Far East.

Surface seawater and marine boundary layer air samples were collected on the ice-breaker R/V Xuelong (Snow Dragon) from the East China Sea to the high Arctic (33.23-84.5° N) in July to September 2010 and have been analyzed for six current-use pesticides (CUPs): trifluralin, endosulfan, chlorothalonil, chlorpyrifos, dacthal, and dicofol. In all oceanic air samples, the six CUPs were detected, showing highest level (>100 pg/m(3)) in the Sea of Japan. Gaseous CUPs basically decreased from East Asia (between 36.6 and 45.1° N) toward Bering and Chukchi Seas. The dissolved CUPs in ocean water ranged widely from air. Trifluralin in seawater was relatively high in the Sea of Japan (35.2° N) and evenly distributed between 36.9 and 72.5° N, but it remained below the detection limit at the highest northern latitudes in Chukchi Sea. In contrast with other CUPs, concentrations of chlorothalonil and dacthal were more abundant in Chukchi Sea and in East Asia. The air-sea gas exchange of CUPs was generally dominated by net deposition. Latitudinal trends of fugacity ratios of α-endosulfan, chlorothalonil, and dacthal showed stronger deposition of these compounds in East Asia than in Chukchi Sea, while trifluralin showed stronger deposition in Chukchi Sea (-455 ± 245 pg/m(2)/day) than in the North Pacific (-241 ± 158 pg/m(2)/day). Air-sea gas exchange of chlorpyrifos varied from net volatilizaiton in East Asia (<40° N) to equilibrium or net deposition in the North Pacific and the Arctic.

We used a chemical transport model to investigate the long-term trends of sulfur deposition in East Asia during 1981-2005. The model reproduced the observed spatial distributions in East Asia of the rate of wet deposition of non-seasalt sulfate (nss-SO42-), volume-weighted mean concentrations of nss-SO42- in precipitation, precipitation, and concentrations in air of gaseous sulfur dioxide and particulate nss-SO42-. The model also reproduced well observed seasonal variations and long-term trends of wet deposition of nss-SO42- in Japan from 1988 to 2005. The increasing rate of wet deposition of nss-SO42- in Japan during 1991-2005 was demonstrated with 99.9% significance for both observed and modeled data. The annual rate of total (wet + dry) sulfur deposition in Japan increased from 15.6 Gmol S y-1 in 1981-1985 to 23.9 Gmol S y-1 in 2001-2005 in response to both increasing contributions from Chinese emissions and the eruption of Miyakejima volcano in 2000. During that 25-year period, approximately 2.1% of the sulfur from Chinese emissions was deposited in Japan. Over the same period, the rate of deposition of sulfur in East Asia increased gradually from 14.2 mmol S m-2 y-1 to 24.0 mmol S m-2 y-1, and the contribution of emissions from China to total sulfur deposition in East Asia increased from 65% to 77%. The contribution of Miyakejima volcano was 3% during 2001-2005. The increase in the sulfur deposition rate was remarkably high on the North China Plain, around Guangzhou, and south of Chongqing. The rate of increase in East Asia was greatest in winter, although the rate of sulfur deposition was highest in summer. Sulfur flux from China to Japan increased by a factor of 2.5 at altitudes of 0-3000 m from 1981 to 2005.

Development of Europe's gas hubs: Implications for East Asia

Directory of Open Access Journals (Sweden)

Xunpeng Shi

2016-10-01

Full Text Available Gas trading hubs have been initially developed in the US in 1980s, UK in 1990s, more recently in European in the 2000s and mulled in East Asia now. Due to its freshness and diversification in nationality, governance and culture, the European hub experience can offer valuable lessons for East Asia. This paper seeks to advance understanding of gas hub development in Europe and provide lessons for East Asia. The European experience highlights that market liberalization and transition of gas pricing mechanism are necessary in creating the competitive markets that are needed for functional gas hubs. Political will and regulations further safeguard the competition environment needed for hub development. Natural factors, such as significant domestic production and culture could have a significant impact on the hub development and transition of pricing mechanism. In East Asia, the path to gas trading hubs might be more difficult than in Europe but a growing market creates an opportunity to start new terms with new contracts. Nevertheless, East Asian needs to work hard to development its indigenous gas or LNG trading hubs.

The situation in South-East Asia is something of a paradox wrought by the end of the cold war and super Power rivalry. As a subregion and integral part of the great Pacific region in cannot be considered in isolation. On the other hand South-East Asia is one of great complexity in terms of its history, peoples and cultures, as well as in its political social and economic systems and orientation. Security picture in South-east Asia in the coming decades depends on a number of impoderables, mainly the situation in Indochina, notably Cambodia, the kind of relationship that will develop between the ASEAN member states and the Indochina countries, as well as with China, as nuclear owning regional Power

The Continental Margin of East Asia: a collage of multiple plates formed by convergence and extension from multiple directions

Mao, J.; Wang, T.; Ludington, S.; Qiu, Z.; Li, Z.

2017-12-01

East Asia is one of the most complex regions in the world. Its margin was divided into 4 parts: Northeast Asia, North China, South China and Southeast Asia. During the Phanerozoic, continental plates of East Asia have interacted successively with a) the Paleo Tethyan Ocean, b) the Tethyan and Paleo Pacific Oceans and c) the Pacific and Indian. In the Early Mesozoic, the Indosinian orogeny is characterized by the convergence and extension within multiple continental plates, whereas the Late Mesozoic Yanshanian orogeny is characterized by both convergence and compression due to oceanic subduction and by widespread extension. We propose this combination as "East Asia Continental Margin type." Except in Northeast Asia, where Jurassic and Cretaeous accretionary complexes are common, most magmatic rocks are the result of reworking of ancient margins of small continental plates; and oceanic island arc basalts and continental margin arc andesites are largely absent. Because South China is adjacent to the western margin of the Pacific Plate, some effects of its westward subduction must be unavoidable, but juvenile arc-related crust has not been identified. The East Asian Continental Margin is characterized by magmatic rocks that are the result of post-convergent tectonics, which differs markedly from the active continental margins of both South and North America. In summary, the chief characteristics of the East Asian Continental Margin are: 1) In Mesozoic, the periphery of multiple blocks experienced magmatism caused by lithospheric delamination and thinning in response to extension punctuated by shorter periods of convergence. 2) The main mechanism of magma generation was the partial melting of crustal rocks, due to underplating by upwelling mafic magma associated with the collapse of orogenic belts and both extension and compression between small continental blocks. 3) During orogeny, mostly high Sr/Y arc-related granitoids formed, whereas during post-orogenic times, A

Monetary Cooperation in East Asia: Major Issues and Future Prospects

Full Text Available The Asian currency crisis in 1997 and the launch of the euro in 1999 made the possibility and desirability of introducing a regional currency union in East Asia a point of debate. At present, the empirical findings and policy implications of previous studies are mixed. We are still in need of theoretical and empirical studies that capture the salient features of East Asia, and give us reliable recommendations for incentive structures, configurations and policy instruments in monetary cooperation in its various stages. This paper aims to review major conceptual and empirical issues relevant to monetary cooperation in East Asia, including proposals for a regional cooperative framework for exchange rate stability or forming a currency union in the region. East Asian countries have no experience with any type of monetary cooperation and all we have are hypothetical predictions. Nevertheless, East Asian countries may be on the brink of an historical evolution to economic and monetary integration, as Europe was half a century ago. The progressive integration of markets in East Asia has conferred a commonality of economic interest upon the countries in the region. As the economic structures of East Asian countries converge with one another through closer ties of trade, investment and finance, the necessity for monetary cooperation will be more likely to emerge in the future. Monetary cooperation in East Asia will be a long process. East Asian countries should make efforts to build collective institutions in the beginning.

Southeast Asia (SEA) is enriched with a complex history of peopling. Malaysia, which is located at the crossroads of SEA, has been recognized as one of the hubs for early human migration. To unravel the genomic complexity of the native inhabitants of Malaysia, we sequenced 12 samples from 3 indigenous populations from Peninsular Malaysia and 4 native populations from North Borneo to a high coverage of 28-37×. We showed that the Negritos from Peninsular Malaysia shared a common ancestor with the East Asians, but exhibited some level of gene flow from South Asia, while the North Borneo populations exhibited closer genetic affinity towards East Asians than the Malays. The analysis of time of divergence suggested that ancestors of Negrito were the earliest settlers in the Malay Peninsula, whom first separated from the Papuans ~ 50-33 thousand years ago (kya), followed by East Asian (~ 40-15 kya), while the divergence time frame between North Borneo and East Asia populations predates the Austronesian expansion period implies a possible pre-Neolithic colonization. Substantial Neanderthal ancestry was confirmed in our genomes, as was observed in other East Asians. However, no significant difference was observed, in terms of the proportion of Denisovan gene flow into these native inhabitants from Malaysia. Judging from the similar amount of introgression in the Southeast Asians and East Asians, our findings suggest that the Denisovan gene flow may have occurred before the divergence of these populations and that the shared similarities are likely an ancestral component.

In the contribution under consideration the author reports on the impact of the United States of America (U.S.A.) in East Asia. The American policy in East Asia is based on two fundamental principles: providing, that no regional authority may provoke the position of the U.S.A., as well as protection of the access to regional markets for the American economy. The U.S.A. fulfill their protective function of their Asiatic partners by means of their maritime superiority with the pacific fleet. Strong-points and safety contracts with Japan and the Republic of Korea form the support of the presence of the U.S. American military. The According to energy security, the interests of the U.S.A. in East Asia are: (a) Secure supply of the national economies in East Asia; (b) Security of the maritime supply systems; (c) Stability and liberalization of the international oil markets; (d) Responsible handling of nuclear energy; (e) Environmental protection. Furthermore, the author describes the conflict potentials between the U.S.A. and the energy safety in East Asia as well as the long-term significance of the energy safety in East Asia

Full Text Available Due to the heterogeneity and complexity of terrestrial ecosystems of East Asia, a better understanding of relationships between climate change and net primary productivity (NPP distribution is important to predict future carbon dynamics. The objective of this study is to analyze the temporal-spatial patterns of NPP in East Asia (10°S - 55°N, 60 - 155°E from 1982 to 2006 using the process-based Boreal Ecosystem Productivity Simulator (BEPS model. Prior to the regional simulation, the annual simulated NPP was validated using field observed NPP demonstrating the ability of BEPS to simulate NPP in different ecosystems of East Asia.

East Asia basin Analysis Project

The United Nations-related Committee for Coordination of Joint Prospecting for Mineral Resources in Asian Offshore Areas (CCOP), in cooperation with the International Union of Geological Sciences and Circum-Pacific Council, is implementing the East Asia Basin Analysis Project. National and regional organizations, principally members of the ASEAN Council of Petroleum, are compiling maps at a scale of 1:2 million and stratigraphic cross sections of basins, with particular initial emphasis on defining and assessing oil and gas plays and with later analytical focus on other sedimentary minerals (e.g., coal, phosphate, evaporites, and uranium). Completion is anticipated in 1988. Two major elements of the project are being contributed from other agencies. (1) Base maps. - The US Geological Survey (USGS) has partly compiled eight sheets covering east Asia that show bathymetry, shorelines, and drainage systems. One sheet also presents topography and selected cultural features. All sheets are scheduled to be completed in 1987. (2) Geotectonic maps. - The Working Group on Studies of East Asian Tectonics and Resources (SEATAR) is now completing 10 transect studies with crustal profiles and strip maps at a scale of 1:1 million. One map for each transect shows a plate tectonic interpretation. Transect coordinators or others will be encouraged to extrapolate between the strips and complete the geotectonic interpretation (on USGS bases) in 1987. The IGCP Project 220 is also compiling on (USGS bases) the tin and tungsten granites of east Asia, emphasizing geochemical data needed to identify predictive models. Other mapping will probably follow mineral-deposit modeling workshops on ophiolotic chromite and regional symposia on oceanic massive sulfide and subvolcanic gold and base metals. Completion may be possible by 1989

North America and Asia Pacific LNG markets

Pirie, J.D.

1997-01-01

The liquefied natural gas (LNG) export opportunities in the Asia Pacific market were reviewed. Some of the differences that affect a North American LNG projects compared to more typical LNG projects were also outlined. The two main aspects of the LNG market in North America include the establishment of LNG import terminals on the east and southern coasts of the United States and the development of export oriented LNG projects. The Pac-Rim LNG project calls for initial delivery to South Korea of 4.0 MTPA by the end of 2000. A large LNG project has also been proposed for the year 2005 which would use Prudhoe Bay gas. Generally, in North America, there is little use for large scale LNG import projects because of the vast pipeline network that delivers gas reliably and at low cost anywhere in North America. However, LNG remains a good alternative for the Asia Pacific region because of the lack of a pipeline network. Also, Japan, Korea and Taiwan, the three main centers for LNG demand, have no domestic energy supplies and rely on imported energy sources. China is another major market opportunity for LNG. The Pac-Rim LNG project differs from others of its kind in that usually, an LNG project is based on the availability of large reservoirs of natural gas owned by state governments and involves production agreements with multi-national oil and gas companies. This scenario is simply not possible in Canada's deregulated environment. In contrast, the existence of upstream facilities, technical expertise, and low capital costs, hence reduced risks and time to develop an LNG project, gives Canada significant advantages. 3 tabs., 3 figs

Diaphorina citri is the vector of 'Candidatus Liberibacter asiaticus', the most widespread pathogen associated huanglongbing, the most serious disease of citrus. To enhance our understanding of the distribution and origin of the psyllid, we investigated the genetic diversity and population structures of 24 populations in Asia and one from Florida based on the mtCOI gene. Simultaneously, genetic diversity and population structures of the primary endosymbiont (P-endosymbiont) 'Candidatus Carsonella ruddii' and secondary endosymbiont (S-endosymbiont) 'Candidatus Profftella armatura' of D. citri were determined with the housekeeping genes. AMOVA analysis indicated that populations of D. citri and its endosymbionts in east and south-east Asia were genetically distinct from populations in Pakistan and Florida. Furthermore, P-endosymbiont populations displayed a strong geographical structure across east and south-east Asia, while low genetic diversity indicated the absence of genetic structure among the populations of D. citri and its S-endosymbiont across these regions. The 'Ca. C. ruddii' is more diverse and structured than the D. citri and the 'Ca. P. armatura' across east and south-east Asia. Multiple introductions of the psyllid have occurred in China. Management application for controlling the pest is proposed based on the genetic information of D. citri and its endosymbionts. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

Composite study of aerosol export events from East Asia and North America

Directory of Open Access Journals (Sweden)

Y. Luan

2013-02-01

Full Text Available We use satellite observations of aerosol optical depth (AOD from the Moderate Resolution Imaging Spectrometer (MODIS together with the GEOS-Chem global chemical transport model to contrast export of aerosols from East Asia and North America during 2004–2010. The GEOS-Chem model reproduces the spatial distribution and temporal variations of Asian aerosol outflow generally well, although a low bias (−30% is found in the model fine mode AOD, particularly during summer. We use the model to identify 244 aerosol pollution export events from E. Asia and 251 export events from N. America over our 7-year study period. When these events are composited by season, we find that the AOD in the outflow is enhanced by 50–100% relative to seasonal mean values. The composite Asian plume splits into one branch going poleward to the Arctic in 3–4 days, with the other crossing the Pacific Ocean in 6–8 days. A fraction of the aerosols is trapped in the subtropical Pacific High during spring and summer. The N. American plume travels to the northeast Atlantic, reaching Europe after 4–5 days. Part of the composite plume turns anticyclonically in the Azores High, where it slowly decays. Both the Asian and N. American export events are favored by a dipole structure in sea-level pressure anomalies, associated with mid-latitude cyclone activity over the respective source regions. This dipole structure during outflow events is a strong feature for all seasons except summer, when convection becomes more important. The observed AOD in the E. Asian outflow exhibits stronger seasonality, with a spring maximum, than the N. American outflow, with a broad spring/summer maximum. The large spring AOD in the Asian outflow is the result of enhanced sulfate and dust aerosol concentrations, but is also due to a larger export efficiency of sulfate and SO₂ from the Asian boundary layer relative to the N. American boundary layer. While the N. American sulfate outflow

Spring Soil Temperature Anomalies over Tibetan Plateau and Summer Droughts/Floods in East Asia

Recurrent extreme climate events, such as droughts and floods, are important features of the climate of East Asia, especially over the Yangtze River basin. Many studies have attributed these episodes to variability and anomaly of global sea surface temperatures (SST) anomaly. In addition, snow in the Tibetan Plateau has also been considered as one of the factors affecting the Asian monsoon variability. However, studies have consistently shown that SST along is unable to explain the extreme climate events fully and snow has difficulty to use as a predictor. Remote effects of observed large-scale land surface temperature (LST) and subsurface temperature variability in Tibetan Plateau (TP) on East Asian regional droughts/floods, however, have been largely ignored. We conjecture that a temporally filtered response to snow anomalies may be preserved in the LST anomaly. In this study, evidence from climate observations and model simulations addresses the LST/SUBT effects. The Maximum Covariance Analysis (MCA) of observational data identifies that a pronounce spring LST anomaly pattern over TP is closely associated with precipitation anomalies in East Asia with a dipole pattern, i.e., negative/positive TP spring LST anomaly is associated with the summer drought/flood over the region south of the Yangtze River and wet/dry conditions to the north of the Yangtze River. Climate models were used to demonstrate a causal relationship between spring cold LST anomaly in the TP and the severe 2003 drought over the southern part of the Yangtze River in eastern Asia. This severe drought resulted in 100 x 106 kg crop yield losses and an economic loss of 5.8 billion Chinese Yuan. The modeling study suggests that the LST effect produced about 58% of observed precipitation deficit; while the SST effect produced about 32% of the drought conditions. Meanwhile, the LST and SST effects also simulated the observed flood over to the north of the Yangtze River. This suggests that inclusion of

Foot-and-mouth disease (FMD) is endemic in Southeast Asia (SEA) and East Asia with circulation of multiple serotypes and multiple genotypes within each serotype of the virus. Although countries like Japan and South Korea in the Far East were free of FMD, in 2010 FMD serotype O (O/Mya-98) outbreaks were recorded and since then South Korea has experienced several FMD outbreaks despite regular vaccination. In this study a total of 85 serotype O FMD viruses (FMDV) isolated from 2007 to 2012 from SEA, East Asia and Far East were characterized by virus neutralisation tests using antisera to four existing (O/HKN/6/83, O/IND/R2/75, O/SKR/2010 and O/PanAsia-2) and one putative (O/MYA/2009) vaccine strains, and by full capsid sequencing. Serological studies revealed broad cross-reactivity with the vaccine strains; O/PanAsia-2 exhibited a good match with 95.3%, O/HKN/6/83 with 91.8%, O/IND/R2/75 with 80%, and the putative strain O/MYA/2009 with 89.4% isolates employed in this study. Similarly O/PanAsia-2 and O/IND/R2/75 vaccines showed a good match with all eight viruses belonging to O-Ind-2001d sublineage whereas the vaccines of O/Mya-98 lineage, O/MYA/2009 and O/SKR/2010 exhibited the lowest match indicating their unsuitability to protect infections from O-Ind-2001d viruses. A Bayesian analysis of the capsid sequence data indicated these circulating viruses (n = 85) to be of either SEA or Middle East-South Asian (ME-SA) topotype. The ME-SA topotype viruses were mainly detected in Lao PDR, Vietnam, Myanmar and Thailand reflecting the trade links with the Indian subcontinent, and also within the SEA countries. Implications of these results in the context of FMD control in SEA and East Asian countries are discussed. Copyright © 2017 The Author(s). Published by Elsevier Ltd.. All rights reserved.

"(East) Asia" as a Platform for Debate: Grouping and Bioethics.

Science.gov (United States)

Sleeboom-Faulkner, Margaret

This article examines the use of the notions of "Asian" and "East Asian" in definitions of bioethics. Using examples from East Asia, I argue that the verbal Asianization of bioethics is based on the notion of "Asia" as a family metaphor and serves as a platform of bioethical debate, networking, and political change. I maintain that the use of "Asia" and "East Asia" to shape bioethics is not so much a sign of inward-looking regionalism, but an attempt to build bridges among Asian countries, while putting up a common stance against what educated elites interpret as undesirable global trends of Westernization through bioethics. Using the notions of "grouping" and "segmentary systems" to show the performative nature of characterizations of (East) Asian bioethics, allowing users to mark regional identity, share meanings, take political positions, and network. Deploying Peter Haas's notion of "epistemic communities," I argue that academic and political elites translate "home" issues into "Asia speak," while at the same time, introducing and giving shape to "new" bioethical issues. Although the "Asianisms" and group-marking activities of Asian networks of bioethics are ideological, thereby engaging in the politics of in/exclusion, they succeed in putting politically sensitive topics on the agenda.

Evaluation of anthropogenic emissions of carbon monoxide in East Asia derived from the observations of atmospheric radon-222 over the western North Pacific

We used the observed CO/"2"2"2Rn ratio in the Asian outflows at Minamitorishima (MNM), Yonagunijima (YON), and Ryori (RYO) in the western North Pacific from 2007 to 2011, together with a three-dimensional chemical transport model (STAG), in order to estimate anthropogenic emissions of CO in East Asia. The measurements captured high-frequency synoptic variations of enhanced "2"2"2Rn (ERN) events associated with the long-range transport of continental air masses. "2"2"2Rn and CO showed high correlation during the ERN events observed at MNM and YON in the winter and spring, but not at RYO. The STAG transport model reproduced well the concentrations of observed "2"2"2Rn when forced with a constant and uniform flux density of 1.0 atom cm"-"2 s"-"1, but underestimated the associated enhancement of synoptically variable CO caused by the underestimated flux values in the EDGAR ver. 4.1 emission database used in the model for East Asia. Better estimates for the East Asian emission were derived using a radon tracer method based on the difference in the enhancement ratio of CO/"2"2"2Rn between the observation and the model. The anthropogenic emissions of CO for China, Japan, and Korea were estimated to be 203 Tg CO yr"-"1, 91% of which originated in China. When compared with other estimated emissions of CO, our estimated result showed consistency with those of the inverse method, whereas the emission database of EDGAR was about 45% smaller than our anthropogenic estimation for China.

Sustainability Measures of Urban Public Transport in Cities: A World Review and Focus on the Asia/Middle East Region

Directory of Open Access Journals (Sweden)

Chris De Gruyter

2016-12-01

Full Text Available Previous studies of public transport sustainability in cities have been very limited to date, particularly in more developing countries located throughout Asia and the Middle East. This paper assesses the sustainability of urban public transport systems in cities by adopting a quantitative measurement framework containing 15 public transport sustainability indicators. It compares aggregate sustainability performance of urban public transport in international regions of cities, and then examines the relative sustainability of selected cities in the Asia and Middle East region. The world region analysis shows that Eastern Europe, Asia, and Latin America achieve the highest aggregate normalised scores for sustainable public transport, in that order. In general, the results suggest that western developed countries (Western Europe, North America, and Oceania have better performance on environmental and social indicators but poorer performance on system effectiveness and economic indicators. Asia and Latin America perform the other way round; better on economic and system effectiveness and worse on social and environmental indicators. Eastern Europe is one of the few regions with higher level performance all round. The city-based analysis of Asia/Middle East suggested that out of the 26 cities studied, the top 3 cities in terms of sustainable public transport in the Asia and Middle East Region are: 1st, Manila (Philippines; 2nd, Tokyo (Japan; and 3rd, Chennai (India. Dubai (United Arab Emirates (UAE, rated 26th, Shizuoka (Japan, rated 25th and Kuala Lumpur (Malaysia, rated 24th were the lowest rated cities. The paper explores the implications of the findings and makes suggestions for future research.

The East Asia, from north to south, including Russia, China, Korea, Japan, Taiwan, Philippines and Indonesia etc., is one of the most active tectonic and natural hazardous regions in the world. The subduction and collision zones, such as the Pacific Plate subducting into the Japan Arc and the Philippine Sea, and the Philippine Sea Plate subducting into the Eurasia Plate, and the collision zones of the Philippine Sea Plate with the Asian continental margin in the Taiwan mountain belt, and the India Plate with the Eurasia Plate in Himalaya mountain belts, distribute widely in this region. It is also the most densely populated areas in the world. More than two billion people (one/third populations of the world) live in East Asia. Most of disastrous natural hazards, such as volcanic eruptions, earthquakes and debris flows induced by floods occur frequently and cause many building collapses and causalities in this area. Geoscientists, therefore, must seriously consider and endeavor for mitigations of the natural hazards and reduction of the properties lose and human death.

Prostate cancer in East Asia: evolving trend over the last decade

Yao Zhu

2015-02-01

Full Text Available Prostate cancer is now becoming an emerging health priority in East Asia. Most of our current knowledge on Prostate cancer has been generated from studies conducted in Western population; however, there is considerable heterogeneity of Prostate cancer between East and West. In this article, we reviewed epidemiologic trends, risk factors, disease characteristics and management of Prostate cancer in East Asian population over the last decade. Growing evidence from East Asia suggests an important role of genetic and environmental risk factors interactions in the carcinogenesis of Prostate cancer. Exposure to westernized diet and life style and improvement in health care in combination contribute substantially to the increasing epidemic in this region. Diagnostic and treatment guidelines in East Asia are largely based on Western knowledge. Although there is a remarkable improvement in the outcome over the last decade, ample evidence suggests an inneglectable difference in diagnostic accuracy, treatment efficacy and adverse events between different populations. The knowledge from western countries should be calibrated in the Asian setting to provide a better race-based treatment approach. In this review, we intend to reveal the evolving trend of Prostate cancer in the last decade, in order to gain evidence to improve Prostate cancer prevention and control in East Asia.

CORRUPTION AND FOREIGN DIRECT INVESTMENT IN EAST ASIA AND SOUTH ASIA: AN ECONOMETRIC STUDY

Directory of Open Access Journals (Sweden)

Rahim M. Quazi

2014-04-01

Full Text Available Many recent FDI studies have focused on the effects of corruption on FDI inflows. Theoretically, corruption can act as either a grabbing hand by raising uncertainty and transaction costs, which should impede FDI, or a helping hand by “greasing” the wheels of commerce in the presence of weak regulatory framework, which should facilitate FDI. This study analyzes the impact of corruption on FDI inflows in East Asia and South Asia – two regions that have recently received huge FDI inflows. Using GLS methodology with 1995-2011 panel data, this study finds that the impact of corruption on FDI is significantly negative and robust, which validates the “grabbing hand” hypothesis. It is also found that, even after accounting for the economic fundamentals, East Asia seems to enjoy a locational advantage in attracting FDI vis-à-vis South Asia. These results further our knowledge of the FDI dynamics, which policymakers should find helpful in devising pro-FDI strategies.

Sulfur dioxide emissions in China and sulfur trends in East Asia since 2000

Directory of Open Access Journals (Sweden)

Z. Lu

2010-07-01

Full Text Available With the rapid development of the economy, the sulfur dioxide (SO₂ emission from China since 2000 is of increasing concern. In this study, we estimate the annual SO₂ emission in China after 2000 using a technology-based methodology specifically for China. From 2000 to 2006, total SO₂ emission in China increased by 53%, from 21.7 Tg to 33.2 Tg, at an annual growth rate of 7.3%. Emissions from power plants are the main sources of SO₂ in China and they increased from 10.6 Tg to 18.6 Tg in the same period. Geographically, emission from north China increased by 85%, whereas that from the south increased by only 28%. The emission growth rate slowed around 2005, and emissions began to decrease after 2006 mainly due to the wide application of flue-gas desulfurization (FGD devices in power plants in response to a new policy of China's government. This paper shows that the trend of estimated SO₂ emission in China is consistent with the trends of SO₂ concentration and acid rain pH and frequency in China, as well as with the increasing trends of background SO₂ and sulfate concentration in East Asia. A longitudinal gradient in the percentage change of urban SO₂ concentration in Japan is found during 2000–2007, indicating that the decrease of urban SO₂ is lower in areas close to the Asian continent. This implies that the transport of increasing SO₂ from the Asian continent partially counteracts the local reduction of SO₂ emission downwind. The aerosol optical depth (AOD products of Moderate Resolution Imaging Spectroradiometer (MODIS are found to be highly correlated with the surface solar radiation (SSR measurements in East Asia. Using MODIS AOD data as a surrogate of SSR, we found that China and East Asia excluding Japan underwent a continuous dimming after 2000, which is in line with the dramatic increase in SO₂ emission in

Application of DNA barcodes in wildlife conservation in Tropical East Asia.

Science.gov (United States)

Wilson, John-James; Sing, Kong-Wah; Lee, Ping-Shin; Wee, Alison K S

2016-10-01

Over the past 50 years, Tropical East Asia has lost more biodiversity than any tropical region. Tropical East Asia is a megadiverse region with an acute taxonomic impediment. DNA barcodes are short standardized DNA sequences used for taxonomic purposes and have the potential to lessen the challenges of biodiversity inventory and assessments in regions where they are most needed. We reviewed DNA barcoding efforts in Tropical East Asia relative to other tropical regions. We suggest DNA barcodes (or metabarcodes from next-generation sequencers) may be especially useful for characterizing and connecting species-level biodiversity units in inventories encompassing taxa lacking formal description (particularly arthropods) and in large-scale, minimal-impact approaches to vertebrate monitoring and population assessments through secondary sources of DNA (invertebrate derived DNA and environmental DNA). We suggest interest and capacity for DNA barcoding are slowly growing in Tropical East Asia, particularly among the younger generation of researchers who can connect with the barcoding analogy and understand the need for new approaches to the conservation challenges being faced. © 2016 Society for Conservation Biology.

Anopheles baimaii is a primary vector of human malaria in the forest settings of Southeast Asia including the north-eastern region of India. Here, the genetic population structure and the basic population genetic parameters of An. baimaii in north-east India were estimated using DNA sequences of the mitochondrial cytochrome oxidase sub unit II (COII) gene. Anopheles baimaii were collected from 26 geo-referenced locations across the seven north-east Indian states and the COII gene was sequenced from 176 individuals across these sites. Fifty-seven COII sequences of An. baimaii from six locations in Bangladesh, Myanmar and Thailand from a previous study were added to this dataset. Altogether, 233 sequences were grouped into eight population groups, to facilitate analyses of genetic diversity, population structure and population history. A star-shaped median joining haplotype network, unimodal mismatch distribution and significantly negative neutrality tests indicated population expansion in An. baimaii with the start of expansion estimated to be ~0.243 million years before present (MYBP) in north-east India. The populations of An. baimaii from north-east India had the highest haplotype and nucleotide diversity with all other populations having a subset of this diversity, likely as the result of range expansion from north-east India. The north-east Indian populations were genetically distinct from those in Bangladesh, Myanmar and Thailand, indicating that mountains, such as the Arakan mountain range between north-east India and Myanmar, are a significant barrier to gene flow. Within north-east India, there was no genetic differentiation among populations with the exception of the Central 2 population in the Barail hills area that was significantly differentiated from other populations. The high genetic distinctiveness of the Central 2 population in the Barail hills area of the north-east India should be confirmed and its epidemiological significance further

Full Text Available We examine how port infrastructure affects trade and role of transport costs in driving exports and imports for East Asia. Existing studies use survey indexes to explain transport costs. These do not link investment in port infrastructure to transport costs. We include in our estimates a variable to represent the congestion of the ports to explain the transport costs. We find that the port congestion has significantly increased the transport costs from East Asia to the United States. Our analysis suggests that increase in port capacity by 10 percent could cut transport cost in East Asia by up to three percent. This translates into a 0.3 to 0.5 percent across-the-board tariff cut.

Panorama 2012 - The oil and gas producing countries of North Africa and the Middle East

International Nuclear Information System (INIS)

Cueille, Jean-Philippe

2011-11-01

Despite the extent of their reserves, oil production in most countries of the Middle East and North Africa is not likely to increase significantly in the years ahead. Exports from the Middle East, 75% of which are to Asia, and those from North Africa, most of which are focused on Europe, should remain stable overall. The increase in gas production will contribute more to meeting fast-growing domestic demand than to boosting exports. Indeed, many Middle Eastern countries are paradoxically experiencing strains on domestic energy supplies due to energy demand stimulated by energy prices that are generally - and artificially - very low, and the adoption of economic development models based on energy-intensive industries.

2018-03-29

The surface temperature variance and its potential change with global warming are most prominent in winter over Northern Hemisphere mid-high latitudes. Consistent wintertime surface temperature variability has been observed over large areas in Eurasia and North America on a broad range of time scales. However, it remains a challenge to quantify where and how the coherent change of temperature anomalies occur over the two continents. Here we demonstrate the coherent change of wintertime surface temperature anomalies over North Asia and the central-eastern parts of North America for the period from 1951 to 2015. This is supported by the results from the empirical orthogonal function analysis of surface temperature and temperature trend anomalies over the Northern Hemisphere extratropical lands and the timeseries analysis of the regional averaged temperature anomalies over North Asia and the Great Plains and Great Lakes. The Asian-Bering-North American (ABNA) teleconnection provides a pathway to connect the regional temperature anomalies over the two continents. The ABNA is also responsible for the decadal variation of the temperature relationship between North Asia and North America.

NASA has contributed to resolve global water issues by utilizing their long-term legacy of remote sensing technologies supported by a state of art software engineering. In this context, NASA Goddard Space Flight Center has developed a land surface model framework to monitor and predict water hazards such as flood and drought with the Land Information System (hereafter LIS) applied to North America and beyond it to include a global coverage. However, it is still challenging to apply the LIS to East-Asia where a rice-paddy agriculture is prevalent compared to other parts of the world, but retains a high population density in this region. Thus, this paper introduces recent efforts from the Korea Water Resources Corporation (K-water) in S. Korea to establish the LIS in East-Asia including Korea, aiming at producing surface hydrology datasets in Asia. One of the ultimate goals of this project is to manage the water hazards in Korea and to provide the water resources dataset in East-Asia by adapting the LIS with their abundantly available hydrometeorological observations to support the LIS applications. Preliminary results from initiating efforts since the beginning of 2017 between NASA and K-water are addressed in the paper to review the possible outcomes after this ongoing project to benefit both entities.

Synergistic impacts of anthropogenic and biogenic emissions on summer surface O3 in East Asia.

Science.gov (United States)

Qu, Yu; An, Junling; Li, Jian

2013-03-01

A factor separation technique and an improved regional air quality model (RAQM) were applied to calculate synergistic contributions of anthropogenic volatile organic compounds (AVOCs), biogenic volatile organic compounds (BVOCs) and nitrogen oxides (NOx) to daily maximum surface 03 (O3DM) concentrations in East Asia in summer (June to August 2000). The summer averaged synergistic impacts of AVOCs and NOx are dominant in most areas of North China, with a maximum of 60 ppbv, while those of BVOCs and NOx are notable only in some limited areas with high BVOC emissions in South China, with a maximum of 25 ppbv. This result implies that BVOCs contribute much less to summer averaged O3DM concentrations than AVOCs in most areas of East Asia at a coarse spatial resolution (1 degree x 1 degree) although global emissions of BVOCs are much greater than those of AVOCs. Daily maximum total contributions of BVOCs can approach 20 ppbv in North China, but they can reach 40 ppbv in South China, approaching or exceeding those in some developed countries in Europe and North America. BVOC emissions in such special areas should be considered when 03 control measures are taken. Synergistic contributions among AVOCs, BVOCs and NOx significantly enhance O3 concentrations in the Beijing-Tianjin-Tangshan region and decrease them in some areas in South China. Thus, the total contributions of BVOCs to O3DM vary significantly from day to day and from location to location. This result suggests that 03 control measures obtained from episodic studies could be limited for long-term applications.

Gas and LNG trading hubs, hub indexation and destination flexibility in East Asia

Shi, Xunpeng; Padinjare Variam, Hari Malamakkavu

2016-01-01

In the East Asian gas markets, issues like gas trading hubs, hub indexed pricing, and destination flexibility are being debated. This paper examines the impact of a change in East Asia's pricing benchmark and contract flexibility on the regional and global gas markets. The paper uses the Nexant World Gas Model, a linear program with global cost minimization as the objective. To our knowledge, this study on hub competition, price benchmark change and contract flexibility improvement in East Asia will be the first in the literature and have real policy relevance. The results show that both price benchmark change and contract flexibility improvements will create an overall benefit for the world and East Asia importers, but the impacts are different among exporters and importers. However, there is no evidence of competition among different benchmark hubs and no evidence that destination restrictions cause the “Asia Premium”. It implies that removal of destination clauses has higher priority than the change to hub indexation for Japan, Korea and Chinese Taipei, but both should be treated equally in China. The study also suggests that East Asian importers should cooperate among themselves and with exporters to facilitate the hub creation and contract changes in East Asia. - Highlights: •Gas trading hubs in Japan and China are not mutually exclusive. •Both price benchmark changes and contract flexibility improvements are beneficial. •The “Asian Premium” is not caused by destination restriction. •Destination flexibility is much more important than hub indexation in East Asia except China. •Hub indexation is as important as destination flexibility in China due to pipeline imports.

Impact of ice sheet induced North Atlantic oscillation on East Asian summer monsoon during an interglacial 500,000 years ago

Marine Isotope Stage (MIS) 13, an interglacial about 500,000 years ago, is unique due to an exceptionally strong East Asia summer monsoon (EASM) occurring in a relatively cool climate with low greenhouse gas concentrations (GHG). This paper attempts to find one of the possible mechanisms for this seeming paradox. Simulations with an Earth System model LOVECLIM show that the presence of ice sheets over North America and Eurasia during MIS-13 induces a positive phase of the winter North Atlantic Oscillation (NAO) like feature. The ocean having a longer memory than the atmosphere, the oceanic anomalies associated with NAO persists until summer. The signals of summer NAO are transmitted to East Asia to reinforce the monsoon there through the stationary waves excited at the Asian Jet entrance. The geopotential height shows clearly a mid-latitude wave train with positive anomalies over the eastern Mediterranean/Caspian Sea and the Okhotsk Sea and a negative anomaly over Lake Baikal. This reinforces the effect of the high-latitude wave train induced independently by the Eurasian ice sheet topography as shown in previous study. These features reinforce the Meiyu front and enhance the precipitation over East Asia. The results obtained from LOVECLIM are further confirmed by an atmospheric general circulation model, ARPEGE.

Impact of climate and land cover changes on tropospheric ozone air quality and public health in East Asia between 1980 and 2010

Fu, Y.; Tai, A. P. K.

2015-09-01

Understanding how historical climate and land cover changes have affected tropospheric ozone in East Asia would help constrain the large uncertainties associated with future East Asian air quality projections. We perform a series of simulations using a global chemical transport model driven by assimilated meteorological data and a suite of land cover and land use data to examine the public health effects associated with changes in climate, land cover, land use, and anthropogenic emissions between the 5-year periods 1981-1985 and 2007-2011 in East Asia. We find that between these two periods land cover change alone could lead to a decrease in summertime surface ozone by up to 4 ppbv in East Asia and ~ 2000 fewer ozone-related premature deaths per year, driven mostly by enhanced dry deposition resulting from climate- and CO2-induced increase in vegetation density, which more than offsets the effect of reduced isoprene emission arising from cropland expansion. Climate change alone could lead to an increase in summertime ozone by 2-10 ppbv in most regions of East Asia and ~ 6000 more premature deaths annually, mostly attributable to warming. The combined impacts (-2 to +12 ppbv) show that while the effect of climate change is more pronounced, land cover change could offset part of the climate effect and lead to a previously unknown public health benefit. While the changes in anthropogenic emissions remain the largest contributor to deteriorating ozone air quality in East Asia over the past 30 years, we show that climate change and land cover changes could lead to a substantial modification of ozone levels, and thus should come into consideration when formulating future air quality management strategies. We also show that the sensitivity of surface ozone to land cover change is more dependent on dry deposition than on isoprene emission in most of East Asia, leading to ozone responses that are quite distinct from that in North America, where most ozone

The genus Rhaponticum in East Asia

Full Text Available The genus Rhaponticum in East Asia has always been a taxon for discussion. Rhaponticum carthamoides from East Siberia comprises three subspecies: carthamoides, chamarensis and orientale. Even though they differ in morphology, they do not have isolated areas. Rhaponticum satzyperovii was recently described and its author pointed out its affinity with Rh. uniflorum. Plant height, stem indumentum, and radical and stem leaf dissection were signaled as the diagnostic characters. Our present study on living and herbarium specimens of Rh. satzyperovii shows that the diagnostic characters are not consistent. The species area was also claimed to be an argument for considering Rh. satzyperovii a distinct species. This area covers the south of the Primorye Province in the Far East of Russia with some locations in the adjacent Jewish Autonomous Region and in China. In our study, the area of Rh. satzyperovii is found to be within the area of Rh. uniflorum and thereafter they turned out to have no disjunction. In East Asia, Rh. uniflorum is characterized by a wide range of morphological variability. We suggest that Rh. satzyperovii should be included within Rh. uniflorum without any taxonomic rank.El género Rhaponticum en el Este de Asia ha sido siempre un taxón discutido.

Prospects of natural gas demand and pipeline projects in the East Asia

International Nuclear Information System (INIS)

Ishii, A.

1997-01-01

The development of the natural gas industry in East Asia was discussed. It was predicted that by 2010, the demand for natural gas could potentially reach 80 billion cubic feet per day. This represents an 8 per cent per year growth rate from a 1995 baseline. Similarly, it was predicted that by 2010, the region's natural gas supply could potentially reach 65 billion cubic feet per day which would represent 2.5 times the supply of natural gas in 1995. The additional demand will most likely be supplied from the Middle East in the form of liquefied natural gas (LNG), from Eastern Russia through pipelines of LNG, or from North America in the form of LNG. Some gas may also be supplied from Central Asia through pipelines. The price and cost of natural gas are major uncertainties in the future of the East Asian gas demand. Pipeline projects from Russia to China were discussed. Japan and Korea are also interested in collaborating on the feasibility study with Russia and China on a 3,400 km pipeline of 60 inch diameter from the Koviktinskoye gas field through Mongolia to Beijing, Tianjin and Korea, transporting 20 to 30 billion cubic metres of gas annually. A natural gas pipeline project transporting gas from the southern edge of the Sakhalin Island to the Tokyo area was also discussed. The project would involve construction of a 2,200 km 40-48 inch pipeline, much of it undersea, transporting 6 to 12 million tonnes of liquid natural gas, annually

Hydrologic effects of land and water management in North America and Asia: 1700–1992

Full Text Available The hydrologic effects of land use changes, dams, and irrigation in North America and Asia over the past 300 years are studied using a macroscale hydrologic model. The simulation results indicate that the expansion of croplands over the last three centuries has resulted in 2.5 and 6 percent increases in annual runoff volumes for North America and Asia, respectively, and that these increases in runoff to some extent have been compensated by increased evapotranspiration caused by irrigation practices. Averaged over the year and the continental scale, the accumulated anthropogenic impacts on surface water fluxes are hence relatively minor. However, for some regions within the continents human activities have altered hydrologic regimes profoundly. Reservoir operations and irrigation practices in the western part of USA and Mexico have resulted in a 25 percent decrease in runoff in June, and a 9 percent decrease in annual runoff volumes reaching the Pacific Ocean. In the area in South East Asia draining to the Pacific Ocean, land use changes have caused an increase in runoff volumes throughout the year, and the average annual increase in runoff is 12 percent.

Uncertainty in biogenic isoprene emissions and its impacts on tropospheric chemistry in East Asia

Han, K.M.; Park, R.S.; Kim, H.K.; Woo, J.H.; Kim, J.; Song, C.H.

2013-01-01

In this study, the accuracy of biogenic isoprene emission fluxes over East Asia during two summer months (July and August) was examined by comparing two tropospheric HCHO columns (Ω HCHO ) obtained from the SCIAMACHY sensor and the Community Multi-scale Air Quality (CMAQ v4.7.1) model simulations, using three available biogenic isoprene emission inventories over East Asia: i) GEIA, ii) MEGAN and iii) MOHYCAN. From this comparative analysis, the tropospheric HCHO columns from the CMAQ model simulations, using the MEGAN and MOHYCAN emission inventories (Ω CMAQ, MEGAN and Ω CMAQ, MOHYCAN ), were found to agree well with the tropospheric HCHO columns from the SCIAMACHY observations (Ω SCIA ). Secondly, the propagation of such uncertainties in the biogenic isoprene emission fluxes to the levels of atmospheric oxidants (e.g., OH and HO 2 ) and other atmospheric gaseous/particulate species over East Asia during the two summer months was also investigated. As the biogenic isoprene emission fluxes decreased from the GEIA to the MEGAN emission inventories, the levels of OH radicals increased by factors of 1.39 and 1.75 over Central East China (CEC) and South China, respectively. Such increases in the OH radical mixing ratios subsequently influence the partitioning of HO y species. For example, the HO 2 /OH ratios from the CMAQ model simulations with GEIA isoprene emissions were 2.7 times larger than those from the CMAQ model simulations based on MEGAN isoprene emissions. The large HO 2 /OH ratios from the CMAQ model simulations with the GEIA biogenic emission were possibly due to the overestimation of GEIA biogenic isoprene emissions over East Asia. It was also shown that such large changes in HO x radicals created large differences on other tropospheric compounds (e.g., NO y chemistry) over East Asia during the summer months. - Highlights: • GEIA isoprene emissions were possibly overestimated over East Asia. • Using MEGAN or MOHYCAN emissions in CMAQ well captured

Research and Development Strategy for Fishery Technology Innovation for Sustainable Fishery Resource Management in North-East Asia

Hidemichi Fujii

2017-12-01

Full Text Available The development of fishery technologies supports food sustainability to achieve a steady supply of fish and fishery products. However, the priorities for research and development (R&D in fishery technologies vary by region due to differences in fish resource availability, environmental concerns, and consumer preferences for fishery products. This study examines trends in fishery technology innovations using data on patents granted as an indicator of changing R&D priorities. To clarify changes in R&D priorities, we apply a decomposition analysis framework that classifies fishery technologies into three types: harvesting, aquaculture, and new products. This study mainly focuses on China, Japan, and Korea as the major fishing countries in the north-east Asia region. The results show that the number of fishery technology patents granted increased between 1993 and 2015; in particular, the number of aquaculture patents granted has grown rapidly since 2012. However, the trend in Japan was the opposite, as the apparent priority given to aquaculture technology innovation decreased between 1993 and 2015. The trends and priority changes for fishery technology inventions vary by country and technology group. This implies that an international policy framework for fishery technology development should recognize that R&D priorities need to reflect diverse characteristics across countries and the technologies employed.

Regimes of Diurnal Variation of Summer Rainfall over Subtropical East Asia

Energy Technology Data Exchange (ETDEWEB)

Yuan W.; Lin W.; Yu, R.; Zhang, M.; Chen, H.; Li, J.

2012-05-01

Using hourly rain gauge records and Tropical Rainfall Measuring Mission 3B42 from 1998 to 2006, the authors present an analysis of the diurnal characteristics of summer rainfall over subtropical East Asia. The study shows that there are four different regimes of distinct diurnal variation of rainfall in both the rain gauge and the satellite data. They are located over the Tibetan Plateau with late-afternoon and midnight peaks, in the western China plain with midnight to early-morning peaks, in the eastern China plain with double peaks in late afternoon and early morning, and over the East China Sea with an early-morning peak. No propagation of diurnal phases is found from the land to the ocean across the coastlines. The different diurnal regimes are highly correlated with the inhomogeneous underlying surface, such as the plateau, plain, and ocean, with physical mechanisms consistent with the large-scale 'mountain-valley' and 'land-sea' breezes and convective instability. These diurnal characteristics over subtropical East Asia can be used as diagnostic metrics to evaluate the physical parameterization and hydrological cycle of climate models over East Asia.

Impacts of the leading modes of tropical Indian Ocean sea surface temperature anomaly on sub-seasonal evolution of the circulation and rainfall over East Asia during boreal spring and summer

Liu, Senfeng; Duan, Anmin

2017-02-01

The two leading modes of the interannual variability of the tropical Indian Ocean (TIO) sea surface temperature (SST) anomaly are the Indian Ocean basin mode (IOBM) and the Indian Ocean dipole mode (IODM) from March to August. In this paper, the relationship between the TIO SST anomaly and the sub-seasonal evolution of the circulation and rainfall over East Asia during boreal spring and summer is investigated by using correlation analysis and composite analysis based on multi-source observation data from 1979 to 2013, together with numerical simulations from an atmospheric general circulation model. The results indicate that the impacts of the IOBM on the circulation and rainfall over East Asia vary remarkably from spring to summer. The anomalous anticyclone over the tropical Northwest Pacific induced by the warm IOBM is closely linked with the Pacific-Japan or East Asia-Pacific teleconnection pattern, which persists from March to August. In the upper troposphere over East Asia, the warm phase of the IOBM generates a significant anticyclonic response from March to May. In June and July, however, the circulation response is characterized by enhanced subtropical westerly flow. A distinct anomalous cyclone is found in August. Overall, the IOBM can exert significant influence on the western North Pacific subtropical high, the South Asian high, and the East Asian jet, which collectively modulate the precipitation anomaly over East Asia. In contrast, the effects of the IODM on the climate anomaly over East Asia are relatively weak in boreal spring and summer. Therefore, studying the impacts of the TIO SST anomaly on the climate anomaly in East Asia should take full account of the different sub-seasonal response during boreal spring and summer.

Here, we give an updated overview of the subtype distribution of lymphomas in East Asia and also present the genome sequencing data on two major subtypes of these tumors. The distribution of lymphoma types/subtypes among East Asian countries is very similar, with a lower proportion of B-cell malignancies and a higher proportion of T/natural killer (NK)-cell lymphomas as compared to Western populations. Extranodal NK/T-cell lymphoma is more frequently observed in East Asia, whereas follicular lymphoma and chronic lymphocytic leukemia, are proportionally lower. The incidence rate of lymphoma subtypes in Asians living in the US was generally intermediate to the general rate in US and Asia, suggesting that both genetic and environmental factors may underlie the geographical variations observed.Key cancer driver mutations have been identified in Asian patients with diffuse large B-cell lymphoma or extranodal NK/T-cell lymphoma through genome sequencing. A distinct somatic mutation profile has also been observed in Chinese diffuse large B-cell lymphoma patients. The incidence and distribution of lymphoma subtypes differed significantly between patients from East Asia and Western countries, suggesting subtype-specific etiologic mechanisms. Further studies on the mechanism underlying these geographical variations may give new insights into our understanding of lymphomagenesis.

An improved understanding of the variations in the mass concentration and size distribution of black carbon (BC) in the free troposphere (FT) over East Asia, where BC emissions are very high, is needed to reliably estimate the radiative forcing of BC in climate models. We measured these parameters and the carbon monoxide (CO) concentration by conducting the Aerosol Radiative Forcing in East Asia (A-FORCE) 2013W aircraft campaign in East Asia in winter 2013 and compared these data with measurements made in the same region in spring 2009. The median BC concentrations in the FT originating from North China (NC) and South China (SC) showed different seasonal variations, which were primarily caused by variations in meteorological conditions. CO concentrations above the background were much higher in SC than in NC in both seasons, suggesting a more active upward transport of CO. In SC, precipitation greatly increased from winter to spring, leading to an increased wet deposition of BC. As a result, the median BC concentration in the FT was highest in SC air in winter. This season and region were optimal for the effective transport of BC from the planetary boundary layer to the FT. The count median diameters of the BC size distributions generally decreased with altitude via wet removal during upward transport. The altitude dependence of the BC size distributions was similar in winter and spring, in accord with the similarity in the BC mixing state. The observed BC concentrations and microphysical properties will be useful for evaluating the performance of climate models.

This study aims to how well the ecological drought index can capture the drought status in the East Asia. We estimated the drought severe index (DSI), which uses the evapotranspiration, potential evapotranspiration and the normalized difference vegetation index (NDVI), suggested by Mu et al. (2013) to define the ecological drought. In addition, the meteorological drought index, which is standardized precipitation and evapotranspiration index (SPEI), are estimated and compared to the DSI. The satellite data by moderate resolution imaging spectroradiometer (MODIS) and advanced very-high-resolution radiometer (AVHRR) are used to analyze the DSI and the monthly precipitation and temperature data in the climate research unit (CRU) are applied to estimate the SPEI for 2000-2013 in the East Asia. We conducted the statistical analyses to investigate the drought characteristics of the ecological and meteorological drought indices (i.e. the DSI and SPEI, respectively) and then compared those characteristics drought indices depending on the drought status. We found the DSI did not well captured the drought status when the categories originally suggested by Mu et al. (2013) are applied to divide the drought status in the study area. Consequently, the modified categories for the DSI in this study is suggested and then applied to define the drought status. The modified categories in this study show the great improvement to capture the drought status in the East Asia even though the results cannot be acquired around Taklamakan desert due to the lack of the satellite data. These results illustrate the ecological drought index, such as the DSI, can be applied for the monitoring of the drought in the East Asia and then can give the detailed information of drought status because the satellite data have the relatively high spatial resolutions compared to the observations such as the CRU data.

In this study, the accuracy of biogenic isoprene emission fluxes over East Asia during two summer months (July and August) was examined by comparing two tropospheric HCHO columns (Ω{sub HCHO}) obtained from the SCIAMACHY sensor and the Community Multi-scale Air Quality (CMAQ v4.7.1) model simulations, using three available biogenic isoprene emission inventories over East Asia: i) GEIA, ii) MEGAN and iii) MOHYCAN. From this comparative analysis, the tropospheric HCHO columns from the CMAQ model simulations, using the MEGAN and MOHYCAN emission inventories (Ω{sub CMAQ,} {sub MEGAN} and Ω{sub CMAQ,} {sub MOHYCAN}), were found to agree well with the tropospheric HCHO columns from the SCIAMACHY observations (Ω{sub SCIA}). Secondly, the propagation of such uncertainties in the biogenic isoprene emission fluxes to the levels of atmospheric oxidants (e.g., OH and HO{sub 2}) and other atmospheric gaseous/particulate species over East Asia during the two summer months was also investigated. As the biogenic isoprene emission fluxes decreased from the GEIA to the MEGAN emission inventories, the levels of OH radicals increased by factors of 1.39 and 1.75 over Central East China (CEC) and South China, respectively. Such increases in the OH radical mixing ratios subsequently influence the partitioning of HO{sub y} species. For example, the HO{sub 2}/OH ratios from the CMAQ model simulations with GEIA isoprene emissions were 2.7 times larger than those from the CMAQ model simulations based on MEGAN isoprene emissions. The large HO{sub 2}/OH ratios from the CMAQ model simulations with the GEIA biogenic emission were possibly due to the overestimation of GEIA biogenic isoprene emissions over East Asia. It was also shown that such large changes in HO{sub x} radicals created large differences on other tropospheric compounds (e.g., NO{sub y} chemistry) over East Asia during the summer months. - Highlights: • GEIA isoprene emissions were possibly overestimated over East Asia. �

The present analysis investigates the spatio-temporal variability of the convective parameters and associated lightning flash rates during the period 1997-2013 including the El Niño and La Niña episode. It reveals that north-western and north-eastern part along the foothills of Himalayas as well as Indo-China peninsular region and South China Sea are much convective prone zones over the South/South-East Asia. The terrain/orography of the Himalayan range, the influence of cross-equatorial low-level jet and large-scale circulation during pre-monsoon and active phase of monsoon, the western Pacific Warm Pool with increased sea surface temperature as well as the solar-heating-originated local instability instigate the convective anomaly to propagate over the north-western and north eastern Indian sub-continent along with the Indo-China peninsula and South China Sea respectively. The land surfaces of the Indian sub-continent and the sea surface of South China Sea possesses significant correlation with lightning flash rates and convective parameters whereas the sea surface surrounding Indian sub-continent do not show such good correlations among them. Although, the occurrence of convective activities during the El Niño (La Niña) gets reduced (increased), the occurrence of lightning flashes gets enhanced (diminished) during this period which may be the direct consequence of warming atmosphere in relation to changing patterns of regional climate.

Many recent FDI studies have focused on the effects of corruption on FDI inflows. Theoretically, corruption can act as either a grabbing hand by raising uncertainty and transaction costs, which should impede FDI, or a helping hand by “greasing” the wheels of commerce in the presence of weak regulatory framework, which should facilitate FDI. This study analyzes the impact of corruption on FDI inflows in East Asia and South Asia – two regions that have recently received huge FDI inflows. Using ...

Future regional nuclear fuel cycle cooperation in East Asia: Energy security costs and benefits

International Nuclear Information System (INIS)

Hippel, David von; Hayes, Peter; Kang, Jungmin; Katsuta, Tadahiro

2011-01-01

Economic growth in East Asia has rapidly increased regional energy, and especially, electricity needs. Many of the countries of East Asia have sought or are seeking to diversify their energy sources and bolster their energy supply and/or environmental security by developing nuclear power. Rapid development of nuclear power in East Asia brings with it concerns regarding nuclear weapons proliferation associated with uranium enrichment and spent nuclear fuel management. This article summarizes the development and analysis of four different scenarios of nuclear fuel cycle management in East Asia, including a scenario where each major nuclear power user develops uranium enrichment and reprocessing of spent fuel individually, scenarios featuring cooperation in the full fuel cycle, and a scenario where reprocessing is avoided in favor of dry cask storage of spent fuel. The material inputs and outputs and costs of key fuel cycle elements under each scenario are summarized. - Highlights: → We evaluate four scenarios of regional nuclear fuel cycle cooperation in East Asia and the Pacific. → The scenarios cover fuel supply, enrichment, transport, reprocessing, and waste management. → We evaluate nuclear material flows, energy use, costs, and qualitative energy security impacts. → Regional cooperation on nuclear fuel cycle issues can help to enhance energy security. → A regional scenario in which reprocessing is rapidly phased out shows security and cost advantages.

For two post-Cold War Russia decades was involved in almost all the basic mechanisms of multilateral cooperation in the Asia-Pacific region. However, often Russia isn't perceived by Asian partners as an equal participant in the Asia-Pacific region, it is felt particularly in the area of multilateral economic cooperation. Russia's entry into the WTO (2011 and the formation of the Common Economic stimulated Russia's engagement in multilateral economic structures.

Full Text Available The particle mixing state plays a significant yet poorly quantified role in aerosol radiative forcing, especially for the mixing of dust (mineral absorbing and anthropogenic pollution (black carbon absorbing over East Asia. We have investigated the absorption enhancement of mixed-type aerosols over East Asia by using the Aerosol Robotic Network observations and radiative transfer model calculations. The mixed-type aerosols exhibit significantly enhanced absorbing ability than the corresponding unmixed dust and anthropogenic aerosols, as revealed in the spectral behavior of absorbing aerosol optical depth, single scattering albedo, and imaginary refractive index. The aerosol radiative efficiencies for the dust, mixed-type, and anthropogenic aerosols are −101.0, −112.9, and −98.3 Wm−2 τ−1 at the bottom of the atmosphere (BOA; −42.3, −22.5, and −39.8 Wm−2 τ−1 at the top of the atmosphere (TOA; and 58.7, 90.3, and 58.5 Wm−2 τ−1 in the atmosphere (ATM, respectively. The BOA cooling and ATM heating efficiencies of the mixed-type aerosols are significantly higher than those of the unmixed aerosol types over the East Asia region, resulting in atmospheric stabilization. In addition, the mixed-type aerosols correspond to a lower TOA cooling efficiency, indicating that the cooling effect by the corresponding individual aerosol components is partially counteracted. We conclude that the interaction between dust and anthropogenic pollution not only represents a viable aerosol formation pathway but also results in unfavorable dispersion conditions, both exacerbating the regional air pollution in East Asia. Our results highlight the necessity to accurately account for the mixing state of aerosols in atmospheric models over East Asia in order to better understand the formation mechanism for regional air pollution and to assess its impacts on human health, weather, and climate.

The red fox (Vulpes vulpes) is the most widely distributed terrestrial carnivore in the world, occurring throughout most of North America, Europe, Asia, and North Africa. In South Korea, however, this species has been drastically reduced due to habitat loss and poaching. Consequently, it is classified as an endangered species in Korea. As a first step of a planned red fox restoration project, preserved red fox museum specimens were used to determine the genetic status of red foxes that had previously inhabited South Korea against red foxes from neighboring countries. Total eighty three mtDNA cytochrome b sequences, including 22 newly obtained East Asian red fox sequences and worldwide red fox sequences from NCBI, were clustered into three clades (i.e., I, II, and III) based on haplotype network and neighbor-joining trees. The mean genetic distance between clades was 2.0%. Clade III contained South Korean and other East Asian samples in addition to Eurasian and North Pacific individuals. In clade III, South Korean individuals were separated into two lineages of Eurasian and North Pacific groups, showing unclear phylogeographic structuring and admixture. This suggests that South Korean red fox populations may have been composed of individuals from these two different genetic lineages.

Many ancestry informative SNP (AISNP) panels have been published. Ancestry resolution in them varies from three to eight continental clusters of populations depending on the panel used. However, none of these panels differentiates well among East Asian populations. To meet this need, we have developed a 74 AISNP panel after analyzing a much larger number of SNPs for Fst and allele frequency differences between two geographically close population groups within East Asia. The 74 AISNP panel can now distinguish at least 10 biogeographic groups of populations globally: Sub-Saharan Africa, North Africa, Europe, Southwest Asia, South Asia, North Asia, East Asia, Southeast Asia, Pacific and Americas. Compared with our previous 55-AISNP panel, Southeast Asia and North Asia are two newly assignable clusters. For individual ancestry assignment, the likelihood ratio and ancestry components were analyzed on a different set of 500 test individuals from 11 populations. All individuals from five of the test populations - Yoruba (YRI), European (CEU), Han Chinese in Henan (CHNH), Rondonian Surui (SUR) and Ticuna (TIC) - were assigned to their appropriate geographical regions unambiguously. For the other test populations, most of the individuals were assigned to their self-identified geographical regions with a certain degree of overlap with adjacent populations. These alternative ancestry components for each individual thus help give a clearer picture of the possible group origins of the individual. We have demonstrated that the new AISNP panel can achieve a deeper resolution of global ancestry. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

In 1991, the G. Bush administration decided to remove away all US surface tactic nuclear weapons everywhere in the world in order to reduce the nuclear warfare risk. This decision has led to the ratification by both Northern Korea and Southern Korea of the declaration on the denuclearization of the Korean peninsula, followed the same year by Mongolia which has become nuclear weapons free. As a consequence of these initiatives, the Center for international strategy, technology and policy (CISTP) of the Georgia institute of technology (Atlanta, USA) has decided the creation of a 'limited nuclear weapons free zone North-East Asia'(LNWFZ), based on cooperation, arms control and non-proliferation. This article describes the genesis of this inter-governmental process of informal diplomacy: proposal of creation of a league for non-nuclear states for North-East Asia, of implementation of an inspection regime and of a cooperative security community, of establishment of confidence building measures and of economic incentives. Then it describes the main components of the LNWFZ project and the obstacles that must be cleared away before its official implementation. (J.S.)

Geopolitics and security in post-cold-war South-East Asia

Regnier, P.

1997-01-01

The most likely scenario is the one in which South-east Asia acquires a greater autonomy, as in Scenario 1. The recomposition of ASEAN as a larger and yet solid entity is far-reaching and requires a lot of mutual internal efforts and policy coordination on external issues. As aforementioned, a situation somewhere between the two sub-scenarios of Scenario I could be achieved. The broadened identity of ASEAN will definitely contribute to the autonomization of South-east Asia as a whole, at least in general geopolitical and security terms. In addition, a greater convergence may develop in economic, strategic and even political areas and gradually produce a subregional order with its own local character and specificities

Review on occurrence and behavior of PCDD/Fs and dl-PCBs in atmosphere of East Asia

Science.gov (United States)

Trinh, Minh Man; Chang, Moo Been

2018-05-01

This paper reviews the data from studies mainly published after 2000 to provide the current understanding of the physicochemical properties, atmospheric occurrence, gas/particle partitioning, fate and temporal trends in atmospheric matrix of PCDD/Fs and dl-PCBs of East Asia. Ambient PCDD/Fs and dl-PCBs concentrations in East Asia are found to be tens to hundreds times higher than that measured in Europe and North America. After strict regulations on PCDD/Fs and dl-PCBs emissions are enacted, the concentrations of these compounds decrease dramatically in Eastern Asian countries. In general, most of PCDD/Fs distribute in particle phase while dl-PCBs majorly exist in gas phase. Three main factors including physicochemical properties of the compounds, properties of particle and atmospheric condition affect the gas/particle partitioning of PCDD/Fs and dl-PCBs. The accuracy of absorption and adsorption models on predicting gas/particle partitioning of PCDD/Fs and dl-PCBs is evaluated. Gas-phase compounds are mostly removed from the atmosphere via reactions with OH radicals while those in particle phase are majorly removed by wet/dry deposition processes. The effects of removing processes and long-range transport on gas/particle partitioning are also discussed.

Regional climate projection based on RCP scenarios in the CORDEX East Asia Domain Using RegCM4

Regional climate projection data is essential to the adaptation and risk management for the expected climate change. In this stduy, we reproduced regional climate over CORDEX East Asia for 72 years from 1979 to 2050 with 50-km resolution using the latest regional climate model version 4, RegCM4, driven by HadGEM2-AO with about 135-km resolution under Intergovernmental Panel on Climate Change (IPCC) Representative Concentration Pathway (RCP) 8.5/4.5. Simulation skills of RegCM4 for the present climate (1980-2005, spin up time: 1979) over CORDEX East Asia are evaluated with CRU-TS (Climate Research Unit Time-Series) 3.0 and GPCP (Global Precipitation Climatology Project). And KMA ground observation data are also used for the detailed assessment of RegCM4 over South Korea. The evaluation results showed that RegCM4 reasonalbly simulated the spatial distribution, and inter-annual and seasonal variations of surface air temperature. However, it showed a non-negligible systemartic biases in the precipitation. In particular, the rainband accompanied by the seasonal march of East Asian summer monsoon was simulated too southward, below 30° N comparing to the GPCP. As a reulst, summer precipitation over South Korea and Japan island was significantly underestimated. Under RCP8.5 (RCP4.5) scenario, annual mean temperature over the CORDEX East Asia is expected to increase by + 1.6 oC(+1.4oC) above the present level (1980-2005) by the end of the future simulation period.

The objective of this research was to obtain thermal performance data for reflective insulations in a South East Asia environment. Thermal resistance data (RSI, m2 ṡ K/W) for reflective insulations are well established from 1-D steady-state tests, but thermal data for reflective insulation in structures like those found in South East Asia are scarce. Data for reflective insulations in South East Asia will add to the worldwide database for this type of energy-conserving material. RSI were obtained from heat flux and temperature data of three identical structures in the same location. One unit did not have insulation above the ceiling, while the second and third units were insulated with reflective insulation with emittance less than 0.05. RSI for the uninsulated test unit varied from 0.37 to 0.40 m2 ṡ K/W. RSI for a single-sheet reflective insulation (woven foil) varied from 2.15 to 2.26 m2 ṡ K/W, while bubble-foil insulation varied from 2.69 to 3.09 m2 ṡ K/W. The range of RSI values resulted from differences in the spacing between the reflective insulation and the roof. In addition, the reflective insulation below the roof lowered attic temperatures by as much as 9.7° C. Reductions in ceiling heat flux of 80 to 90% relative to the uninsulated structure, due to the reflective insulation, were observed.

This study quantifies the costs and impacts of six scenarios for carbon dioxide (CO 2 ) and sulphur dioxide (SO 2 ) emissions in North East Asia (NEA) within an integrated probabilistic analysis. The inclusion of the cooling effect of sulphates means that CO 2 control in China would be likely to increase the regional temperature in NEA in the short-term. This is because CO 2 control measures would also automatically control SO 2 emissions, and so reduce their cooling effect. The scenario that involves no control for CO 2 and SO 2 emissions has the lowest mean total cumulative net present cost (NPC) as compared to scenarios with various SO 2 controls or with CO 2 reduced to 5% below year 1990 levels (in China and Japan), or any combination of SO 2 + CO 2 controls at these levels. The mean value of the total cumulative NPC of climate change damage, acid rain damage, CO 2 and SO 2 control cost in China for no CO 2 or SO 2 control is about US$ 0.1 trillion, compared, for instance, to about US$ 1.1 trillion for CO 2 emission stabilisation at 1990 levels and no SO 2 control. SO 2 control also brings more disadvantages than advantages in China and Japan. The higher mean climate change impacts and control costs outweigh the benefit of lower acid rain damage. However, strict SO 2 control brings more benefits than costs in South Korea where there is a large urban population and the sensitivity to acid rain is high. However, the impacts of emissions and valuation of these effects are very uncertain. Uncertainty analysis shows that the key determinants of the total NPC of costs and damages are exported climate change damages, followed by domestic climate change damages, and acid rain damages. The use of other valuation methods would make health damage bigger than this study's estimation and acid rain damage could be a major concern in the future

The scientific publications in anesthesiology research from East Asian authors have not been reported yet. The present study was designed to analyze the contribution of articles from East Asia to anesthesiology research. Articles published in 17 journals in anesthesiology originating from Japan, China, and South Korea from 2000 to 2009 were retrieved from the PubMed database and Web of Science. From 2000 to 2009, there were 3,076 articles published from East Asia. During this period, there were a notable decrease in publications from Japan and modest increases in publications from both China and South Korea. The average 5-year impact factor of the published articles was similar among the three regions, and China had the highest average number of citations to each article. Anesthesia & Analgesia published more articles than any other journal from all three regions. Our analysis showed that Japan was the most productive region in East Asia, but there was a notable decrease in publications from Japan in 2000-2009. The impact factor of the articles suggests similar levels of scholarship. Anesthesia & Analgesia was the most popular journal in East Asia.

Changes in Cold Surge Occurrence over East Asia in the Future: Role of Thermal Structure

Directory of Open Access Journals (Sweden)

Jin-Woo Heo

2018-06-01

Full Text Available The occurrence of wintertime cold surges (CSs over East Asia is largely controlled by the surface air temperature (SAT distribution at high latitudes and thermal advection in the lower troposphere. The thermodynamic background state over northeastern Asia is associated with the strength of the East Asian winter monsoon and the variation of Arctic Oscillation. This study assesses the importance of the SAT structure with thermal advection in determining the frequency of CS occurrences over East Asia through the analysis of nine atmosphere–ocean coupled global climate models participating in the Coupled Model Intercomparison Project Phase 5. The historical simulations can reproduce the observed typical characteristics of CS development. On the basis of this model performance, ensemble-averaged future simulations under the representative concentration pathway 8.5 project a reduction in CS frequency by 1.1 yr−1 in the late 21st century (2065–2095 compared to the present-day period (1975–2005. The major reason for less frequent CSs in the future is the weakened cold advection, caused by notable SAT warming over the northern part of East Asia. These results suggest that changes in the meridional SAT structure and the associated changes in thermal advection would play a more substantial role than local warming in determining future changes in the frequency of CS occurrences over East Asia.

Background At the southern entrance to East Asia, early population migration has affected most of the Y-chromosome variations of East Asians. Methodology/Principal Findings To assess the isolated genetic structure of Hainan Island and the original genetic structure at the southern entrance, we studied the Y chromosome diversity of 405 Hainan Island aborigines from all the six populations, who have little influence of the recent mainland population relocations and admixtures. Here we report that haplogroups O1a* and O2a* are dominant among Hainan aborigines. In addition, the frequency of the mainland dominant haplogroup O3 is quite low among these aborigines, indicating that they have lived rather isolated. Clustering analyses suggests that the Hainan aborigines have been segregated since about 20 thousand years ago, after two dominant haplogroups entered East Asia (31 to 36 thousand years ago). Conclusions/Significance Our results suggest that Hainan aborigines have been isolated at the entrance to East Asia for about 20 thousand years, whose distinctive genetic characteristics could be used as important controls in many population genetic studies.

MOPITT satellite- and ground-based measurements both suggest of a widespread downward trend in CO concentrations over East Asia during the period 2005-2016. This negative trend is inconsistent with bottom-up inventories of CO emissions, which show a small increase or stable emissions in this region, except for the Multi-resolution Emission Inventory for China (MEIC). We try to reconcile the observed CO trend with emission inventories using an inversion of the MOPITT CO data that provides emissions from primary sources, secondary CO production, and chemical sinks of CO. We find that the decreasing trend of -0.41% yr-1 for CO column concentrations over East Asia is mainly due to a -2.51% yr-1 decrease in emissions from primary sources over this region, or a cumulative decline of -32% from 2005 to 2016. This emission decrease is enough to counterbalance the effect of rising concentrations of CH4 in East Asia, that increase the secondary CO formation at a rate of 1.56% yr-1, according to our multispecies inversion. The reducing emissions are mainly contributed by China. The MEIC inventory is the only one to be consistent with the inversion-diagnosed regional decrease of CO emissions. According to this inventory, decreased CO emissions from four main sectors (iron and steel industries, residential sources, gasoline vehicles, and construction materials industries) in China explain 76% of the inversion-based trend of emissions from East Asia. This result suggests that global inventories underestimated the recent decrease of CO emission factors in China which occurred despite the increasing consumption of carbon-based fuels, and is driven by fast technological changes and emission control measures.

The Spatial and Temporal Distributions of Absorbing Aerosols over East Asia

Full Text Available Absorbing aerosols can strongly absorb solar radiation and have a profound impact on the global and regional climate. Black carbon (BC, organic carbon (OC and dust are three major types of absorbing aerosols. In order to deepen the overall understanding of absorbing aerosols over East Asia and provide a basis for further investigation of its role in enhanced warming in drylands, the spatial-temporal distribution of absorbing aerosols over East Asia for the period of 2005–2016 was investigated based on the Ozone Monitoring Instrument (OMI satellite retrievals. Overall, high values of Aerosol Absorption Optical Depth (AAOD mainly distribute near dust sources as well as BC and OC sources. AAOD reaches its maximum during spring over East Asia as a result of dust activity and biomass burning. Single-scattering albedo (SSA is comparatively high (>0.96 in the most part of East Asia in the summer, indicating the dominance of aerosol scattering. Hyper-arid regions have the highest Aerosol Optical Depth (AOD and AAOD among the five climatic regions, with springtime values up to 0.72 and 0.04, respectively. Humid and sub-humid regions have relatively high AOD and AAOD during the spring and winter and the highest SSA during the summer. AAOD in some areas shows significant upward trends, which is likely due to the increase of BC and OC emission. SSA shows overall downward trends, indicating the enhancement of the aerosol absorption. Analysis of emission inventory and dust index data shows that BC and OC emissions mainly come from the humid regions, while dust sources mainly distribute in drylands.

The origin and evolution of the domestic dog remains a controversial question for the scientific community, with basic aspects such as the place and date of origin, and the number of times dogs were domesticated, open to dispute. Using whole genome sequences from a total of 58 canids (12 gray wolves, 27 primitive dogs from Asia and Africa, and a collection of 19 diverse breeds from across the world), we find that dogs from southern East Asia have significantly higher genetic diversity compared to other populations, and are the most basal group relating to gray wolves, indicating an ancient origin of domestic dogs in southern East Asia 33 000 years ago. Around 15 000 years ago, a subset of ancestral dogs started migrating to the Middle East, Africa and Europe, arriving in Europe at about 10 000 years ago. One of the out of Asia lineages also migrated back to the east, creating a series of admixed populations with the endemic Asian lineages in northern China before migrating to the New World. For the first time, our study unravels an extraordinary journey that the domestic dog has traveled on earth. PMID:26667385

East Asia has the most rapidly growing shipping emissions of both CO2 and traditional air pollutants, but the least in-depth analysis. Full evaluation of all pollutants is needed to assess the impacts of shipping emissions. Here, using an advanced method based on detailed dynamic ship activity data, we show that shipping emissions in East Asia accounted for 16% of global shipping CO2 in 2013, compared to only 4-7% in 2002-2005. Increased emissions lead to large adverse health impacts, with 14,500-37,500 premature deaths per year. Global mean radiative forcing from East Asian shipping is initially negative, but would become positive after approximately eight years for constant current emissions. As a large fraction of vessels are registered elsewhere, joint efforts are necessary to reduce emissions and mitigate the climate and health impacts of shipping in the region.

The Weather Research and Forecasting model with Chemistry (WRF-Chem) is used to investigate the seasonal and annual variations of mineral dust over East Asia during 2007-2011, with a focus on the dust mass balance and radiative forcing. A variety of measurements from in-stu and satellite observations have been used to evaluate simulation results. Generally, WRF-Chem reproduces not only the column variability but also the vertical profile and size distribution of mineral dust over and near the dust source regions of East Asia. We investigate the dust lifecycle and the factors that control the seasonal and spatial variations of dust mass balance and radiative forcing over the seven sub-regions of East Asia, i.e. source regions, the Tibetan Plateau, Northern China, Southern China, the ocean outflow region, and Korea-Japan regions. Results show that, over the source regions, transport and dry deposition are the two dominant sinks. Transport contributes to ~30% of the dust sink over the source regions. Dust results in a surface cooling of up to -14 and -10 W m-2, atmospheric warming of up to 20 and 15 W m-2, and TOA cooling of -5 and -8 W m-2 over the two major dust source regions of East Asia, respectively. Over the Tibetan Plateau, transport is the dominant source with a peak in summer. Over identified outflow regions, maximum dust mass loading in spring is contributed by the transport. Dry and wet depositions are the comparably dominant sinks, but wet deposition is larger than dry deposition over the Korea-Japan region, particularly in spring (70% versus 30%). The WRF-Chem simulations can generally capture the measured features of dust aerosols and its radaitve properties and dust mass balance over East Asia, which provides confidence for use in further investigation of dust impact on climate over East Asia.

In this study, the accuracy of biogenic isoprene emission fluxes over East Asia during two summer months (July and August) was examined by comparing two tropospheric HCHO columns (ΩHCHO) obtained from the SCIAMACHY sensor and the Community Multi-scale Air Quality (CMAQ v4.7.1) model simulations, using three available biogenic isoprene emission inventories over East Asia: i) GEIA, ii) MEGAN and iii) MOHYCAN. From this comparative analysis, the tropospheric HCHO columns from the CMAQ model simulations, using the MEGAN and MOHYCAN emission inventories (Ω(CMAQ, MEGAN) and Ω(CMAQ, MOHYCAN)), were found to agree well with the tropospheric HCHO columns from the SCIAMACHY observations (Ω(SCIA)). Secondly, the propagation of such uncertainties in the biogenic isoprene emission fluxes to the levels of atmospheric oxidants (e.g., OH and HO2) and other atmospheric gaseous/particulate species over East Asia during the two summer months was also investigated. As the biogenic isoprene emission fluxes decreased from the GEIA to the MEGAN emission inventories, the levels of OH radicals increased by factors of 1.39 and 1.75 over Central East China (CEC) and South China, respectively. Such increases in the OH radical mixing ratios subsequently influence the partitioning of HO(y) species. For example, the HO2/OH ratios from the CMAQ model simulations with GEIA isoprene emissions were 2.7 times larger than those from the CMAQ model simulations based on MEGAN isoprene emissions. The large HO2/OH ratios from the CMAQ model simulations with the GEIA biogenic emission were possibly due to the overestimation of GEIA biogenic isoprene emissions over East Asia. It was also shown that such large changes in HO(x) radicals created large differences on other tropospheric compounds (e.g., NO(y) chemistry) over East Asia during the summer months.

Analysis of the summertime buildup of tropospheric ozone abundances over the Middle East and North Africa as observed by the Tropospheric Emission Spectrometer instrument

We use the GEOS-Chem chemical transport model to interpret observations of tropospheric ozone from the Tropospheric Emission Spectrometer (TES) satellite instrument in summer 2005. Observations from TES reveal elevated ozone in the middle troposphere (500-400 hPa) across North Africa and the Middle East. Observed ozone abundances in the middle troposphere are at a maximum in summer and a minimum in winter, consistent with the previously predicted summertime "Middle East ozone maximum." This summertime enhancement in ozone is associated with the Arabian and Sahara anticyclones, centered over the Zagros and Atlas Mountains, respectively. These anticyclones isolate the middle troposphere over northeast Africa and the Middle East, with westerlies to the north and easterlies to the south, facilitating the buildup of ozone. Over the Middle East, we find that in situ production and transport from Asia provides comparable contributions of 30-35% to the ozone buildup. Over North Africa, in situ production is dominant (at about 20%), with transport from Asia, North America, and equatorial Africa each contributing about 10-15% to the total ozone. We find that although the eastern Mediterranean is characterized by strong descent in the middle and upper troposphere in summer, transport from the boundary layer accounts for about 25% of the local Middle Eastern contribution to the ozone enhancement in the middle troposphere. This upward transport of boundary layer air is associated with orographic lifting along the Zagros Mountains in Iran and the Asir and Hijaz Mountain ranges in Saudi Arabia, and is consistent with TES observations of deuterated water.

Quest for Middle East oil: the US versus the Asia-Pacific region

International Nuclear Information System (INIS)

Salameh, Mamdouh G.

2003-01-01

Two very powerful geopolitical factors will decisively determine whether the quest for Middle East oil (mainly Gulf oil) could enhance the global oil security or could lead to oil supply disruptions and also instability and conflict in the Asia-Pacific region. The two factors are the United States' growing dependence on oil imports from the Middle East and the Asia-Pacific region's thirst for oil and the increasingly likely Chinese dependence on oil from the region. The Asia-Pacific countries are increasingly growing concerned about their ability to supply enough oil to fuel future economic growth. The region's phenomenal economic growth up to July 1997 and its economic recovery since then, and its steadily rising energy needs lend urgency to the question of how the region would meet its considerable energy challenges. This paper will endeavour to analyze the impact of this growing dependence on Middle East oil, on global oil supplies, the price of oil and global oil security. It will argue that such dependence on a volatile region like the Middle East and the perception of scarcer energy resources in the Asia-Pacific region, have the potential to lead to conflict in both regions unless these issues are dealt with in geoeconomic rather than geostrategic terms. The paper will strongly express the view that potential conflicts can be resolved not by force but through markets and investment and also through the diversification of energy sources and the promotion of alternative energy development and use across the region

Methane emissions in East Asia for 2000-2011 estimated using an atmospheric Bayesian inversion

We present methane (CH4) emissions for East Asia from a Bayesian inversion of CH4 mole fraction and stable isotope (δ13C-CH4) measurements. Emissions were estimated at monthly resolution from 2000 to 2011. A posteriori, the total emission for East Asia increased from 43 ± 4 to 59 ± 4 Tg yr-1 between 2000 and 2011, owing largely to the increase in emissions from China, from 39 ± 4 to 54 ± 4 Tg yr-1, while emissions in other East Asian countries remained relatively stable. For China, South Korea, and Japan, the total emissions were smaller than the prior estimates (i.e., Emission Database for Global Atmospheric Research 4.2 FT2010 for anthropogenic emissions) by an average of 29%, 20%, and 23%, respectively. For Mongolia, Taiwan, and North Korea, the total emission was less than 2 Tg yr-1 and was not significantly different from the prior. The largest reductions in emissions, compared to the prior, occurred in summer in regions important for rice agriculture suggesting that this source is overestimated in the prior. Furthermore, an analysis of the isotope data suggests that the prior underestimates emissions from landfills and ruminant animals for winter 2010 to spring 2011 (no data available for other times). The inversion also found a lower average emission trend for China, 1.2 Tg yr-1 compared to 2.8 Tg yr-1 in the prior. This trend was not constant, however, and increased significantly after 2005, up to 2.0 Tg yr-1. Overall, the changes in emissions from China explain up to 40% of the increase in global emissions in the 2000s.

Yellow fever, Asia and the East African slave trade.

Science.gov (United States)

Cathey, John T; Marr, John S

2014-05-01

Yellow fever is endemic in parts of sub-Saharan Africa and South America, yet its principal vectors--species of mosquito of the genus Aedes--are found throughout tropical and subtropical latitudes. Phylogenetic analyses indicate that yellow fever originated in Africa and that its spread to the New World coincided with the slave trade, but why yellow fever has never appeared in Asia remains a mystery. None of several previously proposed explanations for its absence there is considered satisfactory. We contrast the trans-Atlantic slave trade, and trade across the Sahara and to the Arabian Peninsula and Mesopotamia, with that to Far East and Southeast Asian ports before abolition of the African slave trade, and before the scientific community understood the transmission vector of yellow fever and the viral life cycle, and the need for shipboard mosquito control. We propose that these differences in slave trading had a primary role in the avoidance of yellow fever transmission into Asia in the centuries before the 20(th) century. The relatively small volume of the Black African slave trade between Africa and East and Southeast Asia has heretofore been largely ignored. Although focal epidemics may have occurred, the volume was insufficient to reach the threshold for endemicity.

The Impacts of East Asia FTA: A CGE Model Simulation Study

Directory of Open Access Journals (Sweden)

Mitsuyo Ando

2007-12-01

Full Text Available In light of the on-going discussions of the possibility of an East Asia FTA, this paper attempts to estimate the impacts of an East Asia FTA using a Computable General Equilibrium (CGE model. Although most previous simulation studies on the impacts of FTAs focus only on the liberalization of trade in goods, our paper attempts to take into account other aspects of FTAs such as capital accumulation and trade and investment facilitation measures. Our simulation analysis finds that an ASEAN+3 FTA is the most desirable FTA of eight hypothetical FTAs in East Asia to all member countries at the macro level. At the same time, our results demonstrate the significant impacts of capital accumulation and various trade and investment facilitation and coordination programs. At the sectoral level, many sectors gain in terms of output and trade. Although some sectors in certain countries indeed lose in terms of output as a result of an ASEAN+3, most of them experience increases in both exports and imports, even if output declines. These results indicate that the larger the coverage in terms of membership as well as contents such as trade and FDI liberalization and facilitation, and economic cooperation is, the greater benefits can be accrued to the members.

Full Text Available The article demonstrates that during the extended period of cooperation, the IMF’s activities have had both positive and negative impact on the development of economies of the East Asia region. On the one hand, the IMF initiated and supported in-depth reforms that formed a solid basis for sustainable development and growth of countries of the region. On the other hand, the IMF failed to achieve positive outcomes in some specific important areas mostly because of its unbalanced policies and due to disregard to specific needs of particular countries of the region. Furthermore, the IMF failed to properly discharge one of its main mandates to effectively predict, address, and overcome international financial crisis tendencies and processes that emerged from the fragility and the lack of sustainability of the global liquidity system at the regional level, and in particular during the Asian crisis of 1997-98. The IMF’s failures led to a significant decrease of cooperation with the East Asia region and gave rise to the IMF stigma and subsequent regionalism processes. Although quite uncertain, any further cooperation may only be carried out on a new basis with due consideration of the specificity of the region and the particular countries. Methodology. The author provides first, based on the IMF’s official statistics and data, an analysis of the cooperation between the IMF and the East Asia region in order to identify main achievements and failures and then explores possible forms of further cooperation with due regard to all stakeholders’ interests and needs. The author aims to demonstrate, based on the IMF’s experience in East Asia, that cooperation between the IMF and particular countries or regions is a complex and challenging process, which most often involves the need to give due consideration to various important factors, including country-based specificities and risks of reluctance to the IMF’s activities.

This study examines the ability of the Beijing Climate Center Climate System Model (BCC_CSM) to predict the meridional pattern of summer precipitation over East Asia-Northwest Pacific (EA-NWP) and its East Asia-Pacific (EAP) teleconnection. The differences of summer precipitation modes of the empirical orthogonal function and the bias of atmospheric circulations over EA-NWP are analyzed to determine the reason for the precipitation prediction errors. Results indicate that the BCC_CSM could not reproduce the positive-negative-positive meridional tripole pattern from south to north that differs markedly from that observed over the last 20 years. This failure can be attributed to the bias of the BCC_CSM hindcasts of the summer EAP teleconnection and the low predictability of 500 hPa at the mid-high latitude lobe of the EAP. Meanwhile, the BCC_CSM hindcasts' deficiencies of atmospheric responses to SST anomalies over the Indonesia maritime continent (IMC) resulted in opposite and geographically shifted geopotential anomalies at 500 hPa as well as wind and vorticity anomalies at 850 hPa, rendering the BCC_CSM unable to correctly reproduce the EAP teleconnection pattern. Understanding these two problems will help further improve BCC_CSM's summer precipitation forecasting ability over EA-NWP.

Hydroclimatic variability in East Asia: A case study in the Yangtze river basin

2017-12-01

New regional patterns of droughts and flooding are emerging at south and east Asia river basins, but the causal climatic mechanisms underlying these new hydrological extreme events are yet unknown. The Southern Oscillation, monsoons, and sea surface temperatures affect hydrological conditions in Asia at different spatiotemporal scales. During the negative phase of the Southern Oscillation, anticyclone systems occur more frequently and modulate precipitation patterns near the southeast coast of China. Monsoons related to the Intertropical convergence zone (ITCZ) locations have been used to explain regional droughts and flooding. Moreover, sea surface temperatures affect wind anomalies and thermocline adjustments across the Pacific and Indian oceans. Here we propose using a major catchment in China, the Yangtze river basin, to understand regional modes of climate variability influencing local hydrological dynamics in Asia. By decomposing the variance of precipitation and hydrological time series, we are able to quantify the relative contributions of the Southern Oscillation, monsoons, and sea surface temperatures to the Yangtze river discharges. Our results suggest that the Southern Oscillation has a relatively weak effect on discharges, whereas the Indian and western North Pacific monsoons are important for the upstream and downstream Yangtze river, respectively. Furthermore, rising Pacific sea surface temperatures may be related to more intensive precipitation at the downstream basin. Based on the hydroclimatic relationships identified here, we discuss future scenarios of changing environmental conditions in the region.

Given the existence of plenty of river valleys connecting Southeast and East Asia, it is possible that some inland route(s) might have been adopted by the initial settlers to migrate into the interior of East Asia. Here we analyzed mitochondrial DNA (mtDNA) HVS variants of 845 newly collected individuals from 14 Myanmar populations and 5,907 published individuals from 115 populations from Myanmar and its surroundings. Enrichment of basal lineages with the highest genetic diversity in Myanmar suggests that Myanmar was likely one of the differentiation centers of the early modern humans. Intriguingly, some haplogroups were shared merely between Myanmar and southwestern China, hinting certain genetic connection between both regions. Further analyses revealed that such connection was in fact attributed to both recent gene flow and certain ancient dispersals from Myanmar to southwestern China during 25-10 kya, suggesting that, besides the coastal route, the early modern humans also adopted an inland dispersal route to populate the interior of East Asia.

Phytogeography of the tropical north-east African mountains

I. Friis

1983-11-01

Full Text Available The tropical north-east African mountains are tentatively divided into four phytochoria, the formal rank of which is not defined. The division is based on patterns of distribution and endemism in the region. The recognition of a distinct Afromontane phytochorion is now well established (Chapman & White, 1970; Werger, 1978; White, 1978. However, there is still very little information on the phytogeography of the individual mountains or mountain systems. This study hopes to fill a little of the gap by analysing distribution patterns and patterns of endemism in the flora of the tropical north-east African mountains. The north-east African mountain system is the largest in tropical Africa (see e.g. map in White, 1978. At the core of this system is the large Ethiopian massif, around which are located various mountains and mountain chains. These include the Red Sea Hills in the Sudan, the mountain chain in northern Somalia, the south-west Arabian mountains, and the Imatong mountains of south-east Sudan. The latter are often referred to the East African mountain system (White, 1978 but. as I will point out later, they also have a close connection with the south-west highlands of Ethiopia. The paper presents some results of my study of the mountain flora of tropical north-east Africa, particularly the forest species. Where no source is indicated, the data are from my own unpublished studies.

East Asian dust (EAD) exerts considerable impacts on the energy balance and climate/climate change of the earth system through its influence on solar and terrestrial radiation, cloud properties, and precipitation efficiency. Providing an accurate description of the life cycle and climate effects of EAD is therefore critical to better understanding of climate change and socioeconomic development in East Asia and even worldwide. Dust modeling has undergone substantial development since the late 1990s, associated with improved understanding of the role of EAD in the earth system. Here, we review the achievements and progress made in recent decades in terms of dust modeling research, including dust emissions, long-range transport, radiative forcing (RF), and climate effects of dust particles over East Asia. Numerous efforts in dust/EAD modeling have been directed towards furnishing more sophisticated physical and chemical processes into the models on higher spatial resolutions. Meanwhile, more systematic observations and more advanced retrieval methods for instruments that address EAD related science issues have made it possible to evaluate model results and quantify the role of EAD in the earth system, and to further reduce the uncertainties in EAD simulations. Though much progress has been made, large discrepancies and knowledge gaps still exist among EAD simulations. The deficiencies and limitations that pertain to the performance of the EAD simulations referred to in the present study are also discussed.

Ciguatera fish poisoning in East Asia and southeast Asia.

Science.gov (United States)

Chan, Thomas Y K

2015-06-02

In the coastal countries of East Asia and Southeast Asia, ciguatera should be common because of the extensive tropical and subtropical coral reefs along the coasts and in the neighboring seas with ciguatoxic fishes. An extensive search of journal databases, the Internet and the government websites was performed to identify all reports of ciguatera from the regions. Based on the official data and large published case series, the incidence of ciguatera was higher in the coastal cities (Hong Kong, Foshan, Zhongshan) of southern China than in Japan (Okinawa Prefecture). In Singapore, ciguatera appeared to be almost unknown. In other countries, only isolated cases or small case series were reported, but under-reporting was assumed to be common. Ciguatera may cause severe acute illness and prolonged neurological symptoms. Ciguatera represents an important public health issue for endemic regions, with significant socio-economic impact. Coordinated strategies to improve risk assessment, risk management and risk communication are required. The systematic collection of accurate data on the incidence and epidemiology of ciguatera should enable better assessment and management of its risk. Much more work needs to be done to define the size threshold for important coral reef fish species from different regions, above which the risk of ciguatera significantly increases.

Nuclear nonproliferation strategy in Asia

International Nuclear Information System (INIS)

Jenkins, F.W.

1989-07-01

The most immediate danger of a further spread of nuclear weapons in Asia is in South Asia, where both India and Pakistan have developed the means of producing nuclear explosive materials. In East Asia, North Korea appears to be in the early stages of a weapon-related nuclear program, and before the end of the century South Korea or Taiwan could revive their past efforts to move closer to a nuclear weapons capability. Over the longer run, Japan could conceivably decide to abandon its present strong opposition to the acquisition of nuclear Weapons. At present, the United States has largely separate approaches to the nuclear weapon proliferation problems in South Asia and in East Asia. This paper argues that these separate approaches should be strengthened and integrated into a broader regional nonproliferation strategy. This regional strategy would have three major strands: inducing India and Pakistan to agree not to produce nuclear weapons or test nuclear explosive devices for a specific period; bolstering the existing nonproliferation regime, principally by maintaining nonproliferation incentives and involving China more in the nonproliferation regime; and encouraging regional cooperation in peaceful uses of nuclear energy

Atmospheric Circulation Patterns over East Asia and Their Connection with Summer Precipitation and Surface Air Temperature in Eastern China during 1961-2013

Science.gov (United States)

Li, Shuping; Hou, Wei; Feng, Guolin

2018-04-01

Based on the NCEP/NCAR reanalysis data and Chinese observational data during 1961-2013, atmospheric circulation patterns over East Asia in summer and their connection with precipitation and surface air temperature in eastern China as well as associated external forcing are investigated. Three patterns of the atmospheric circulation are identified, all with quasi-barotropic structures: (1) the East Asia/Pacific (EAP) pattern, (2) the Baikal Lake/Okhotsk Sea (BLOS) pattern, and (3) the eastern China/northern Okhotsk Sea (ECNOS) pattern. The positive EAP pattern significantly increases precipitation over the Yangtze River valley and favors cooling north of the Yangtze River and warming south of the Yangtze River in summer. The warm sea surface temperature anomalies over the tropical Indian Ocean suppress convection over the northwestern subtropical Pacific through the Ekman divergence induced by a Kelvin wave and excite the EAP pattern. The positive BLOS pattern is associated with below-average precipitation south of the Yangtze River and robust cooling over northeastern China. This pattern is triggered by anomalous spring sea ice concentration in the northern Barents Sea. The anomalous sea ice concentration contributes to a Rossby wave activity flux originating from the Greenland Sea, which propagates eastward to North Pacific. The positive ECNOS pattern leads to below-average precipitation and significant warming over northeastern China in summer. The reduced soil moisture associated with the earlier spring snowmelt enhances surface warming over Mongolia and northeastern China and the later spring snowmelt leads to surface cooling over Far East in summer, both of which are responsible for the formation of the ECNOS pattern.

Alternatives of Cross-Border Securities Settlement System in East Asia

Hee-Yul Chai

2005-12-01

Full Text Available The establishment of cross-border securities settlement system is a very important element of regional capital market integration. Despite its importance, relatively few arguments, both theoretical and practical, have been advanced on the subject. This paper aims to examine the alternatives of cross-border securities settlement system in East Asia, and analyse the feasibility and the advantages and disadvantages of each alternative. The paper underlines the need to develop a multi-currency DVP securities settlement system. The conceivable alternatives of East Asia's cross-border securities settlement system can be divided into decentralized system and centralized system. It is possible to consider a large array of institutional settings according to the depository/settlement methods. The comparison of the alternatives is based on economic efficiency, feasibility and institutional location of settlement system. In view of these criteria, it is argued that a 'big-bang' approach toward imperfectly cenralized system is the most desirable alternative.

Gas and LNG pricing and trading hub in East Asia: An introduction

Xunpeng Shi

2016-10-01

Full Text Available This paper summarizes the four papers in the special issues on ‘Gas and LNG pricing and trading hub in East Asia’. The papers examine lessons and experience from European hub development, other commodity, the Japanese history on developing of futures markets and inter-fuel substitution in East Asia. The papers finds that liquid futures market is the key to formulate benchmark prices while a well-developed spot market is the foundation; political will and strong leadership are required to overcome the power of incumbents and to restructure the gas market that impede the the development of competitive markets; and East Asia needs to develop its indigenous gas or LNG trading hubs even in low oil prices period and its developing market allows easier changes in new contracts than in existing ones. This hub development requires governments to go through tough domestic market reforms, including liberalization and cooperation with each other and with gas exporters.

New fossil seeds of Eurya (Theaceae from East Asia and their paleobiogeographic implications

Directory of Open Access Journals (Sweden)

Hai Zhu

2016-06-01

Full Text Available Eurya has an excellent fossil record in Europe, but it has only a few fossil occurrences in East Asia though this vast area houses the highest modern diversity of the genus. In this study, three-dimensionally preserved fossil seeds of Eurya stigmosa (Ludwig Mai from the late Pliocene of northwestern Yunnan, southwestern China are described. The seeds are compressed and flattened, slightly campylotropous, and nearly circular to slightly angular in shape. The surface of the seeds is sculptured by a distinctive foveolate pattern, consisting of funnel-shaped and finely pitted cells. Each seed valve contains a reniform or horseshoe-shaped embryo cavity, a characteristic condyle structure and an internal raphe. These fossil seeds represent one of the few fossil records of Eurya in East Asia. This new finding therefore largely extends the distributional ranges of Eurya during Neogene. Fossil records summarized here show that Eurya persisted in Europe until the early Pleistocene, but disappeared thereafter. The genus might have first appeared in East Asia no later than the late Oligocene, and dispersed widely in regions such as Japan, Nepal, and southwestern China.

Donor issues in Indonesia: A developing country in South East Asia.

Soedarmono, Yuyun S M

2010-01-01

In most developing countries in South East Asia blood services have not been treated properly as an important service to support health program. Indonesia as a large archipelago country in South East Asia has specific obstacles in managing a blood service. To position the country blood service profile especially in term of donor issues, we compared our blood service with that in other South East Asia countries. Indonesia has 17 thousand islands with 220 million inhabitants. Blood services have been mostly run by the Indonesian Red Cross as a government assignment since 1950. Donor recruitment programs have been directed toward 100% of Voluntary Non Remunerated Blood Donor (VNRD), which now have reached 81.3%. Dissemination of information on VNRD, donor recruiter's training and VNRD appreciation programs are strategies to increase and maintain the VNRD. Limited female donors and insufficient blood supply during the fasting month and holidays constitute major challenges. Low hemoglobin level, low body weight and fear are reasons for low number of female donors. Poor management of blood stock during fasting month, long holidays and also poor networking of blood supply are reasons for insufficient blood supply during the year. Considering the great size of Indonesia with different ethnic groups and cultures, worsened by lack of infrastructure, decisive and effective strategies in donor recruitment and retention programs are needed.

Forecasting of Currency Crises in East Asia

Directory of Open Access Journals (Sweden)

Chi-Young Song

2005-06-01

Full Text Available In this paper, we have developed a forecasting system for currency crisis in East Asia based on a signaling approach. Our system uses 15 monthly indicators of five East Asian countries including Indonesia, Korea, Malaysia, the Philippines and Thailand that were severely hit by the currency crisis in 1997. We investigate the performance of the system through deploying out-of-sample forecasting for the periods both before and after the 1997 East Asian currency crisis. Unlike the existing research based on the signaling approach, our out-of-sample forecasting does not fix the in-sample period. The out-of-sample forecasting between July 1995 and June 1997 shows that prior to breakout of the crisis, several indicators including real exchange rates and exports sent frequent warnings to all crisis-hit East Asian countries except the Philippines. This may indicate that a signaling-based early warning system for currency crisis could have been an useful method of forecasting the East Asian crisis. On the other hand, we also find that our forecasting system often generates warning signals during the out-of-sample period between July 1999 and June 2001. Since we have not observed any currency crisis in this region after 1998, these are all false alarms, indicating that our system may be seriously exposed to the type II error. We can, however, mitigate this problem if we adjust the optimal critical values of indicators depending on the preferences of forecasting system manager.

Late Jurassic-Early Cretaceous continental convergence and intracontinental orogenesis in East Asia: A synthesis of the Yanshan Revolution

The basic tectonic framework of continental East Asia was produced by a series of nearly contemporaneous orogenic events in the late Middle Jurassic to Early Cretaceous. Commonly, the Late Mesozoic orogenic processes were characterized by continent-continent collision, large-scale thrusting, strike-slip faulting and intense crustal shortening, crustal thickening, regional anatexis and metamorphism, followed by large-scale lithospheric extension, rifting and magmatism. To better understand the geological processes, this paper reviews and synthesizes existing multi-disciplinary geologic data related to sedimentation, tectonics, magmatism, metamorphism and geochemistry, and proposes a two-stage tectono-thermal evolutionary history of East Asia during the late Middle Jurassic to Early Cretaceous (ca. 170-120 Ma). In the first stage, three orogenic belts along the continental margins were formed coevally at ca. 170-135 Ma, i.e., the north Mongol-Okhotsk orogen, the east paleo-Pacific coastal orogen, and the west Bangong-Nujiang orogen. Tectonism related to the coastal orogen caused extensive intracontinental folding and thrusting that resulted in a depositional hiatus in the Late Jurassic, as well as crustal anatexis that generated syn-kinematic granites, adakites and migmatites. The lithosphere of the East Asian continent was thickened, reaching a maximum during the latest Jurassic or the earliest Cretaceous. In the second stage (ca. 135-120 Ma), delamination of the thickened lithosphere resulted in a remarkable (>120 km) lithospheric thinning and the development of mantle-derived magmatism, mineralization, metamorphic core complexes and rift basins. The Middle Jurassic-Early Cretaceous subduction of oceanic plates (paleo-Pacific, meso-Tethys, and Mongol-Okhotsk) and continent-continent collision (e.g. Lhasa and Qiangtang) along the East Asian continental margins produced broad coastal and intracontinental orogens. These significant tectonic activities, marked by

Carbon emission, energy consumption and intermediate goods trade: A regional study of East Asia

International Nuclear Information System (INIS)

Zhang, Jingjing

2015-01-01

Using country level panel data from East Asia over the period 1998–2011, this paper examines the implications of international production fragmentation-induced intermediate goods trade on the link between energy consumption and carbon pollution. The paper focuses on the interaction effect between energy consumption and trade in intermediate goods on carbon emission. The empirical results presented suggest that international trade in intermediate goods decreases the positive impact on carbon emission of energy consumption. When compared with the trade in final goods, intermediate goods trade contributes to a greater decrease in carbon pollution resulting from energy consumption. These results confirm that the link between energy consumption and carbon pollution in East Asia is significantly affected by international production fragmentation-induced trade in intermediate goods. The results presented in this paper have some important policy implications. - Highlights: • This paper tests the role of intermediates trade in energy-development nexus. • Empirical study is based on data of East Asia. • International trade can reduce the carbon pollution caused by energy use. • Intermediates trade has higher moderating effect than non-intermediate trade.

The Asia-Pacific region: non-proliferation and other disarmament issues

International Nuclear Information System (INIS)

1992-01-01

In the past few years, the United States and the former Soviet Union began to adjust their force structures in Asia-Pacific region. In this respect, a large range of issues have been raised in discussions on the non-proliferation of nuclear and other weapons of mass destruction. Apart from the issues and trends related to proliferation, military expenditure, arms transfer and other disarmament matters, the specific situations in the respective subregions of South-East Asia, South Asia and North-East Asia were discussed. Comprehensive and verified commitments not to possess any such weapons is stressed as the main goal of the meeting. It is vitally important that opportunities that were opened should be seized to prevent the spread of nuclear, chemical, biological as well as highly destabilizing conventional weapons

Inland post-glacial dispersal in East Asia revealed by mitochondrial haplogroup M9a'b

Directory of Open Access Journals (Sweden)

Wang Wen-Zhi

2011-01-01

Full Text Available Abstract Background Archaeological studies have revealed a series of cultural changes around the Last Glacial Maximum in East Asia; whether these changes left any signatures in the gene pool of East Asians remains poorly indicated. To achieve deeper insights into the demographic history of modern humans in East Asia around the Last Glacial Maximum, we extensively analyzed mitochondrial DNA haplogroup M9a'b, a specific haplogroup that was suggested to have some potential for tracing the migration around the Last Glacial Maximum in East Eurasia. Results A total of 837 M9a'b mitochondrial DNAs (583 from the literature, while the remaining 254 were newly collected in this study pinpointed from over 28,000 subjects residing across East Eurasia were studied here. Fifty-nine representative samples were further selected for total mitochondrial DNA sequencing so we could better understand the phylogeny within M9a'b. Based on the updated phylogeny, an extensive phylogeographic analysis was carried out to reveal the differentiation of haplogroup M9a'b and to reconstruct the dispersal histories. Conclusions Our results indicated that southern China and/or Southeast Asia likely served as the source of some post-Last Glacial Maximum dispersal(s. The detailed dissection of haplogroup M9a'b revealed the existence of an inland dispersal in mainland East Asia during the post-glacial period. It was this dispersal that expanded not only to western China but also to northeast India and the south Himalaya region. A similar phylogeographic distribution pattern was also observed for haplogroup F1c, thus substantiating our proposition. This inland post-glacial dispersal was in agreement with the spread of the Mesolithic culture originating in South China and northern Vietnam.

Food for humans is one of the most important of all global issues. It is a critical determinant of planetary and individual health, of economic development, of how sustainable energy and water supplies are, and its security a powerful determinant of peace or conflict. Those who assume leadership for the integrity of food and health systems have great responsibility. The IUNS (International Union of Nutritional Sciences), regional and national nutrition science and food technology organizations have concern about the leadership capacity available and required in what are rapidly changing and increasingly demanding circumstances. These include persistent poverty and hunger, climate change which threatens the sustainability of food production and fragile financial systems which are making food less affordable for many. North East Asia (NEA) is a major region for its population size, its economic wealth and disparities, its food production, its life expectancies among the best and its global reach. In 2008, for those of Chinese ancestry and of wider Asian origin, Nutrition Leadership training has been conducted in Hangzhou, Shanghai, Seoul and Taiwan (Hsinchu and Zhunan). Ninety prospective young leaders participated in all. Several successful early career Asian nutrition scientists and professionals served as role models. Senior colleagues acted as mentors for groups of 2 or 3. With mentors, the concept of leadership has been examined, careers and roles explored, knowledge and skills honed for a different future, and plans made to network in mutual support. Early feedback indicates that new opportunities have been created and seized.

Full Text Available Abstract Background Carassius auratus is a primary freshwater fish with bisexual diploid and unisexual gynogenetic triploid lineages. It is distributed widely in Eurasia and is especially common in East Asia. Although several genetic studies have been conducted on C. auratus, they have not provided clear phylogenetic and evolutionary descriptions of this fish, probably due to selection bias in sampling sites and the DNA regions analysed. As the first step in clarifying the evolutionary entity of the world's Carassius fishes, we attempted to clarify the phylogeny of C. auratus populations distributed in East Asia. Results We conducted a detailed analysis of a large dataset of mitochondrial gene sequences [CR, 323 bp, 672 sequences (528 sequenced + 144 downloaded; CR + ND4 + ND5 + cyt b, 4669 bp in total, 53 sequences] obtained from C. auratus in East Asia. Our phylogeographic analysis revealed two superlineages, one distributed mainly among the Japanese main islands and the other in various regions in and around the Eurasian continent, including the Ryukyus and Taiwan. The two superlineages include seven lineages with high regional specificity that are composed of endemic populations indigenous to each region. The divergence time of the seven lineages was estimated to be 0.2 million years ago (Mya by a fossil-based method and 1.0-1.9 Mya by the molecular clock method. The antiquity and endemism of these lineages suggest that they are native to their respective regions, although some seem to have been affected by the artificial introduction of C. auratus belonging to other lineages. Triploids of C. auratus did not form a monophyletic lineage but were clustered mostly with sympatric diploids. Conclusions The results of the present study revealed the existence of two superlineages of C. auratus in East Asia that include seven lineages endemic to each of the seven regions examined. The lack of substantial genetic separation between triploids and

Full Text Available Cylindrocladiella spp. are widely distributed especially in tropical and sub-tropical regions, where they are mainly known as saprobes although some species are plant pathogens. Very little is known about these fungi in South-East Asia. The aim of this study was to identify a collection of Cylindrocladiella isolates from soils collected in forest nurseries and plantations in Vietnam and Malaysia. This was achieved using DNA sequence comparisons and morphological observations. The study revealed two previously described species, Cy. lageniformis and Cy. peruviana as well as five novel taxa, described here as Cy. arbusta sp. nov., Cy. malesiana sp. nov., Cy. obpyriformis sp. nov., Cy. parvispora sp. nov. and Cy. solicola sp. nov. A relatively small collection of isolates from a limited geographic sampling revealed an unexpectedly high level of Cylindrocladiella diversity suggesting that many more species in this genus await discovery in South-East Asia.

Previous climate modeling studies suggest that the surface uplift of the Himalaya-Tibetan plateau (TP) is a crucial parameter for the onset and intensification of the East Asian monsoon during the Cenozoic. Most of these studies have only considered the Himalaya-TP in its present location between ∼26°N and ∼40°N despite numerous recent geophysical studies that reconstruct the Himalaya-TP 10° or more of latitude to the south during the early Paleogene. We have designed a series of climate simulations to explore the sensitivity of East Asian climate to the latitude of the Himalaya-TP. Our simulations suggest that the East Asian climate strongly depends on the latitude of the Himalaya-TP. Surface uplift of a proto-Himalaya-TP in the subtropics intensifies aridity throughout inland Asia north of ∼40°N and enhances precipitation over East Asia. In contrast, the rise of a proto-Himalaya-TP in the tropics only slightly intensifies aridity in inland Asia north of ∼40°N, and slightly increases precipitation in East Asia. Importantly, this climate sensitivity to the latitudinal position of the Himalaya-TP is non-linear, particularly for precipitation across East Asia. The simulated precipitation patterns across East Asia are significantly different between our scenarios in which a proto-plateau is situated between ∼11°N and ∼25°N and between ∼20°N and ∼33°N, but they are similar when the plateau translates northward from between ∼20°N and ∼33°N to its modern position. Our simulations, when interpreted in the context of climate proxy data from Central Asia, support geophysically-based paleogeographic reconstructions in which the southern margin of a modern-elevation proto-Himalaya-TP was located at ∼20°N or further north in the Eocene.

2014-10-15

To balance the need to develop nuclear power for peaceful purposes and to prevent the risks of nuclear proliferation, multinational approach (MNA) of nuclear fuel cycle has been developed on the basis that nuclear technology is managed not by individual countries, but by a community of state-level technology users, so that countries can have access to the benefits of peaceful applications of nuclear technology while any proliferation intention will be collectively eliminated by the community. This paper focuses on why MNA is still necessary for this region in the non-proliferation and nuclear power development context of East Asia. Following the analysis on the need for MNA, the possible challenges and necessary considerations for new proposal of MNA in East Asia are provided. The paper is concluded with a summarization on the necessity and challenges of MNA as well as further direction for research. From the analysis in this paper, it could be concluded that the development of MNA for nuclear fuel cycle is a complex process, of which the success could only be assured by the combination of political effort, feasible technology choice, and practical approach. The complexity and political-implied nature of MNA in East Asia have resulted in the failure of every proposals in this region. Nevertheless, given the numerous issues of the regional nuclear industry, MNA has become once again a reasonable choice for the East Asia countries, which are thriving to a solution to assure fuel supply and back-end fuel cycle management while trying to eliminate the risk of nuclear proliferation in the region. The creation of such cooperation regime will have to surpass the obstacles of international relations, regional political tension and scope of approach. In this paper, a comprehensive coverage of the MNA for nuclear fuel cycle is not presented due to space limitation. Rather, this paper focuses on analysing the advantages and obstacles of MNA in East Asia, with the hope that it

Asian dust events, transport of dust particles from arid and semi-arid areas in China and Mongolia to the east by prevailing westerlies, are often observed in Japan in spring. In recent decades, consumption of fossil fuels has markedly increased in mainland East Asia with rapid economic growth, and severe air pollution has occurred. A part of air pollutants including mutagens, such as polycyclic aromatic hydrocarbons (PAHs), generated in mainland East Asia are thought to be transported to Japan by the prevailing westerlies, like Asian dust, and winter monsoon. The objective of this study was to clarify the long-range transport of mutagens and other air pollutants in East Asia. Thus, we collected total suspended particles (TSP) at a rural town in western Japan, namely, Yurihama in Tottori Prefecture, for 1 year (June 2012-May 2013), and investigated their chemical constituents and mutagenicity. Many TSP collected from January to March showed high mutagenicity toward Salmonella typhimurium YG1024 with and without S9 mix, and high levels of lead (Pb) and sulfate ions (SO4 (2-)), which are indicators of transboundary air pollutions from mainland East Asia, were detected in those TSP. A large amount of iron, which is an indicator of sand, was found in highly mutagenic TSP collected in March, but not in TSP collected in January and February. High levels of PAHs were detected in highly mutagenic TSP collected from January to March. The ratios of the concentration of fluoranthene to those of fluoranthene and pyrene suggested that the main source of PAHs in TSP collected in winter and spring was coal and biomass combustion. Backward trajectories of air masses on days when high levels of mutagenicity were found indicated that these air masses had traveled from eastern or northern China to Yurihama. These results suggest that high levels of mutagens were transported from mainland East Asia to western Japan, and this transportation accompanied Asian dust in March, but not in

Reconstruction of regional mean temperature for East Asia since 1900s and its uncertainties

Science.gov (United States)

Hua, W.

2017-12-01

Regional average surface air temperature (SAT) is one of the key variables often used to investigate climate change. Unfortunately, because of the limited observations over East Asia, there were also some gaps in the observation data sampling for regional mean SAT analysis, which was important to estimate past climate change. In this study, the regional average temperature of East Asia since 1900s is calculated by the Empirical Orthogonal Function (EOF)-based optimal interpolation (OA) method with considering the data errors. The results show that our estimate is more precise and robust than the results from simple average, which provides a better way for past climate reconstruction. In addition to the reconstructed regional average SAT anomaly time series, we also estimated uncertainties of reconstruction. The root mean square error (RMSE) results show that the the error decreases with respect to time, and are not sufficiently large to alter the conclusions on the persist warming in East Asia during twenty-first century. Moreover, the test of influence of data error on reconstruction clearly shows the sensitivity of reconstruction to the size of the data error.

2014-12-01

Impact of mineral dust and biomass burning aerosols on air quality has been well documented in the last few decades, but the knowledge about their interactions with anthropogenic emission and their impacts on regional climate is very limited (IPCC, 2007). While East Asia is greatly affected by dust storms in spring from Taklamakan and Gobi deserts (Huang et al., 2010; Li et al., 2012), it also suffers from significant biomass burning emission from Southeast Asia during the same season. Observations from both surface monitoring and satellite data indicated that mineral dust and biomass burning aerosols may approach to coastal area of East Asia simultaneously, thus have a very unique impact on the local atmospheric environment and regional climate. In this study, we first investigated the inter-annual variations of biomass burning and dust aerosols emission for 5 consecutive years from 2006-2010 to estimate the upper and lower limits and correlation with meteorology conditions, and then evaluate their impacts with a chemical transport system. Our preliminary results indicated that biomass burning has a strong correlation with precipitation over Southeast Asia, which could drive the emission varying from 542 Tg in 2008 to 945 Tg in 2010, according to FLAMBE emission inventory (Reid et al., 2009). Mineral dust also demonstrated a strong dependence on wind filed. These inter-annual/annual variations will also lead to different findings and impacts on air quality in East Asia.

2002-01-01

Russia's Far East and East Siberia are emerging as new major sources of gas supplies for East Asian energy markets. Thanks to ongoing and earmarked resource and infrastructure developments in Sakhalin, Yakutia (Sakha) and Irkutsk, by around 2020 these poorly developed but naturally endowed areas of the country's East can provide between 50 and 70 Bcm/yr (5-7 Bcfd) of natural gas, including up to 10 Mt/yr of LNG, available for exports to neighbouring Pacific countries (primarily to the PRC, Japan, South Korea as well as to Taiwan and the U.S. West Coast). This can noticeably reshape today's matrix of the Asia-Pacific energy flows and even destabilize the regional gas market. (author)

The quantity and quality of publications in critical care medicine from East Asia haven't been reported. This study aimed to investigate the contribution of publications from East Asia. Articles from China, Japan and South Korea in 2005 to 2014 were retrieved from Web of Science and Pubmed. The number of publications, impact factor, citation, and article types were analyzed. There were 3076 publications from East Asia (1720 from China, 913 from Japan, and 443 from South Korea). There were a significant decrease in publications from Japan (p = 0.024) and significant increases from China (p = 0.000) and South Korea (p = 0.009). From 2006, the number of articles from China exceed Japan. China had the highest total impact factor (6618.48) and citation (18416), followed by Japan (4566.03; 15440) and South Korea (1998.19; 5599). Japan had the highest mean impact factor (5.00) and citations (16.91), followed by South Korea (4.51; 12.64) and China (3.85; 10.71). China and South Korea`s contributions to critical care medicine had significant increases during the past 10 years, while Japan had a significant decrease. China was the most productive region in East Asia since 2006. Japan had the highest quality research output.

Poland’s Trade with East Asia: An Outlier Approach

Directory of Open Access Journals (Sweden)

2015-12-01

Full Text Available Poland achieved an excellent reputation for economic transformation during the recent global recession. The European debt crisis, however, quickly forced the reorientation of Poland’s trade outside of the European Union (EU, especially toward the dynamic region of East Asia. This study analyzes time series data from 1999 to 2013 to detect outliers in order to determine the bilateral trade paths between Poland and each East Asian country during the events of Poland’s accession to the EU in 2004, the global financial crisis from 2008 to 2009, and the European debt crisis from 2010 to 2013. From the Polish standpoint, the results showed significantly clustering outliers in the above periods and in the general trade paths from dependence through distancing and improvement to the chance of approaching East Asian partners. This study also shows that not only China but also several other countries present an excellent opportunity for boosting bilateral trade, especially with regard to Poland’s exports.

Hard science is essential to restoring soft-sediment intertidal habitats in burgeoning East Asia.

Science.gov (United States)

Lee, Shing Yip; Khim, Jong Seong

2017-02-01

Intertidal soft-sediment ecosystems such as mangrove, saltmarsh, and tidal flats face multiple stresses along the burgeoning East Asia coastline. In addition to direct habitat loss, ecosystem structure, function, and capacity for ecosystem services of these habitats are significantly affected by anthropogenic loss of hydrologic connectivity, introduction of invasive exotic species, and chemical pollution. These dramatic changes to ecosystem structure and function are illustrated by four case studies along the East Asian coast: the Mai Po Marshes in Hong Kong, the Yunxiao wetlands in Fujian, China, and the Lake Sihwa and Saemangeum tidal flats in Korea. While investment in restoration is increasing significantly in the region, the lack of key basic knowledge on aspects of the behaviour of intertidal soft-sediment ecosystems, particularly those in Asia, impairs the effectiveness of these efforts. The relationship between biodiversity and ecosystem function for relatively species-poor mangrove, seagrass, and saltmarsh systems has implications for restoration targeting monospecific plantations. The trajectory of recovery and return of ecosystem function and services is also poorly known, and may deviate from simple expectations. As many introduced species have become established along the East Asian coast, their long-term impact on ecosystem function as well as the socio-economics of coastal communities demand a multidisciplinary approach to assessing options for restoration and management. These knowledge gaps require urgent attention in order to inform future restoration and management of intertidal soft-sediment ecosystems in fast-developing East Asia. Copyright © 2016 Elsevier Ltd.

Finance and Inequality – Evidence from East Asia

Directory of Open Access Journals (Sweden)

Mohamed Salah Mansour

2015-08-01

Full Text Available The economic debate about inequality has occupied a huge place in the scientific discourse of the last decades. Several factors have been identified as causes for the rising wealth and income inequality in various regions such as economic growth, capital return and intergenerational wealth. In this paper, East Asia is chosen as a regional focus for the analysis due to the region’s specific characteristics and history regarding inequality. Until the end of the 1980s, the region experienced a period of so-called “growth with equity” where high economic growth rates were associated with decreasing poverty and inequality. In recent years, however, growth in East Asia has gone hand in hand with inequality. This shift from “growth with equity” to “growth with inequality” makes the region worth investigating. The paper focuses particularly on the size of the financial sector, analyzing its role and impact on the development of inequality. Therefore, the theoretical connection and the natural relationship between poverty, inequality, economic growth as well as the size of the financial sector are discussed. Indicators, proxies and measurements for these variables are identified, based on existing literature. The main analysis delivers an answer to the research question of whether and how financial development affects the inequality in a society. For the analysis, cross-country and panel data for the ASEAN+3 countries from 1960-2012 are used.

Bowen, Kathryn J; Ebi, Kristie L

2017-09-01

Countries in the World Health Organization (WHO) South-East Asia Region are particularly vulnerable to a changing climate. Changes in extreme weather events, undernutrition and the spread of infectious diseases are projected to increase the number of deaths due to climate change by 2030, indicating the need to strengthen activities for adaptation and mitigation. With support from the WHO Regional Office for South-East Asia and others, countries have started to include climate change as a key consideration in their national public health policies. Further efforts are needed to develop evidence-based responses; garner the necessary support from partner ministries; and access funding for activities related to health and climate change. National action plans for climate change generally identify health as one of their priorities; however, limited information is available on implementation processes, including which ministries and departments would be involved; the time frame; stakeholder responsibilities; and how the projects would be financed. While progress is being made, efforts are needed to increase the capacity of health systems to manage the health risks of climate change in South-East Asia, if population health is to be protected and strengthened while addressing changing weather and climate patterns. Enhancing the resilience of health systems is key to ensuring a sustainable path to improved planetary and population health.

This is because the Impossible Trinity model does not fit the actual circumstances very closely. Capital flows are dominated by factors other ...

Improvement of PM10 prediction in East Asia using inverse modeling

Koo, Youn-Seo; Choi, Dae-Ryun; Kwon, Hi-Yong; Jang, Young-Kee; Han, Jin-Seok

2015-04-01

Aerosols from anthropogenic emissions in industrialized region in China as well as dust emissions from southern Mongolia and northern China that transport along prevailing northwestern wind have a large influence on the air quality in Korea. The emission inventory in the East Asia region is an important factor in chemical transport modeling (CTM) for PM10 (particulate matters less than 10 ㎛ in aerodynamic diameter) forecasts and air quality management in Korea. Most previous studies showed that predictions of PM10 mass concentration by the CTM were underestimated when comparing with observational data. In order to fill the gap in discrepancies between observations and CTM predictions, the inverse Bayesian approach with Comprehensive Air-quality Model with extension (CAMx) forward model was applied to obtain optimized a posteriori PM10 emissions in East Asia. The predicted PM10 concentrations with a priori emission were first compared with observations at monitoring sites in China and Korea for January and August 2008. The comparison showed that PM10 concentrations with a priori PM10 emissions for anthropogenic and dust sources were generally under-predicted. The result from the inverse modeling indicated that anthropogenic PM10 emissions in the industrialized and urbanized areas in China were underestimated while dust emissions from desert and barren soil in southern Mongolia and northern China were overestimated. A priori PM10 emissions from northeastern China regions including Shenyang, Changchun, and Harbin were underestimated by about 300% (i.e., the ratio of a posteriori to a priori PM10 emission was a factor of about 3). The predictions of PM10 concentrations with a posteriori emission showed better agreement with the observations, implying that the inverse modeling minimized the discrepancies in the model predictions by improving PM10 emissions in East Asia.

Depth variations of P-wave azimuthal anisotropy beneath East Asia

Science.gov (United States)

Wei, W.; Zhao, D.; Xu, J.

2017-12-01

We present a new P-wave anisotropic tomographic model beneath East Asia by inverting a total of 1,488,531 P wave arrival-time data recorded by the regional seismic networks in East Asia and temporary seismic arrays deployed on the Tibetan Plateau. Our results provide important new insights into the subducting Indian, Pacific and Philippine Sea plates and mantle dynamics in East Asia. Our tomographic images show that the northern limit of the subducting Indian plate has reached the Jinsha River suture in eastern Tibet. A striking variation of P-wave azimuthal anisotropy is revealed in the Indian lithosphere: the fast velocity direction (FVD) is NE-SW beneath the Indian continent, whereas the FVD is arc parallel beneath the Himalaya and Tibetan Plateau, which may reflect re-orientation of minerals due to lithospheric extension, in response to the India-Eurasia collision. The FVD in the subducting Philippine Sea plate beneath the Ryukyu arc is NE-SW(trench parallel), which is consistent with the spreading direction of the West Philippine Basin during its initial opening stage, suggesting that it may reflect the fossil anisotropy. A circular pattern of FVDs is revealed around the Philippine Sea slab beneath SE China. We suggest that it reflects asthenospheric strain caused by toroidal mantle flow around the edge of the subducting slab. We find a striking variation of the FVD with depth in the subducting Pacific slab beneath the Northeast Japan arc. It may be caused by slab dehydration that changed elastic properties of the slab with depth. The FVD in the mantle wedge beneath the Northeast Japan and Ryukyu arcs is trench normal, which reflects subduction-induced convection. Beneath the Kuril and Izu-Bonin arcs where oblique subduction occurs, the FVD in the mantle wedge is nearly normal to the moving direction of the downgoing Pacific plate, suggesting that the oblique subduction together with the complex slab morphology have disturbed the mantle flow.

Since the onset of the Asian crisis, what characterizes the East Asian exchange rates has been a topic of considerable discussion. In the pre-crisis period, the de facto pegs to the U.S. dollar sometimes destabilized the real "effective" exchange rates of these currencies. Several economists have, thus, proposed the desirability of intermediate exchange rate regimes in East Asia that might stabilize their effective exchange rates. The post-crisis experience in East Asia, however, taught us th...

Bottom-up design of a gas futures market in East Asia: Lessons from the Dojima rice exchange

Directory of Open Access Journals (Sweden)

2016-10-01

Full Text Available The natural gas market in East Asia remains fragmented without a functioning benchmark price to duly reflect the dynamics of demand and supply forces in the region. A functional regional gas futures market, which is highly dependent on the presence of well-developed physical spot trading, is yet to be established. Since the intra-regional pipeline connection is largely non-existent in East Asia, it is the LNG spot cargo trading that is likely to become the basis for the regional gas futures market. This paper offers a novel approach to understanding the development of such a market by analyzing the experience of a different commodity market – the Dojima Rice Exchange (DRE – and identifying potentially transferrable lessons in the market design and the role of government regulations. Based on the case study analysis, implications for the development of natural gas trading hubs in East Asia are offered and an LNG futures exchange design is put forward.

Even among HIV-infected patients who fully suppress plasma HIV RNA replication on antiretroviral therapy, genetic (e.g. CCL3L1 copy number), viral (e.g. tropism) and environmental (e.g. chronic exposure to microbial antigens) factors influence CD4 recovery. These factors differ markedly around the world and therefore the expected CD4 recovery during HIV RNA suppression may differ globally. We evaluated HIV-infected adults from North America, West Africa, East Africa, Southern Africa and Asia starting non-nucleoside reverse transcriptase inhibitorbased regimens containing efavirenz or nevirapine, who achieved at least one HIV RNA level Africa showed diminished CD4 recovery as compared with other regions. Three years after antiretroviral therapy initiation, the mean CD4 count for a prototypical patient with a pre-therapy CD4 count of 150/ml was 529/ml [95% confidence interval (CI): 517–541] in North America, 494/ml (95% CI: 429–559) in West Africa, 515/ml (95% CI: 508–522) in Southern Africa, 503/ml (95% CI: 478–528) in Asia and 437/ml (95% CI: 425–449) in East Africa. CD4 recovery during HIV RNA suppression is diminished in East Africa as compared with other regions of the world, and observed differences are large enough to potentially influence clinical outcomes. Epidemiological analyses on a global scale can identify macroscopic effects unobservable at the clinical, national or individual regional level.

Crustal evolution in north-east and east Africa from model Nd ages

The authors present the results of an Nd isotope study on the major rock units of the Pan-African (1,100-500 Myr BP) terrane. Charnockites from Jabel Uweinat, a basement inlier at the junction of Egypt, Libya and the Sudan, yield middle Archaean model Nd ages, whilst model ages of < 1,200 Myr have been obtained in a belt from the Eastern Desert of Egypt to north-west Kenya. Overall, the Pan-African rocks from north-east and east Africa and those from the Damara of Namibia exhibit a wide range of epsilonsub(Nd)(T) from +7.5 to -18.0 which reflects regional changes in tectonic style and is not readily reconciled with simple models for the evolution of average continental crust.

North-east India, being a corridor to South-east Asia, is believed to play an important role in transmitting drug resistant Plasmodium falciparum malaria to India and South Asia. North-east India was the first place in India to record the emergence of drug resistance to chloroquine as well as sulphadoxine/pyrimethamine. Presently chloroquine resistance is widespread all over the North-east India and resistance to other anti-malarials is increasing. In this study both in vivo therapeutic efficacy and molecular assays were used to screen the spectrum of drug resistance to chloroquine and sulphadoxine/pyrimethamine in the circulating P. falciparum strains. A total of 220 P. falciparum positives subjects were enrolled in the study for therapeutic assessment of chloroquine and sulphadoxine/pyrimethamine and assessment of point mutations conferring resistances to these drugs were carried out by genotyping the isolates following standard methods. Overall clinical failures in sulphadoxine/pyrimethamine and chloroquine were found 12.6 and 69.5% respectively, while overall treatment failures recorded were 13.7 and 81.5% in the two arms. Nearly all (99.0%) the isolates had mutant pfcrt genotype (76T), while 68% had mutant pfmdr-1 genotype (86Y). Mutation in dhps 437 codon was the most prevalent one while dhfr codon 108 showed 100% mutation. A total of 23 unique haplotypes at the dhps locus and 7 at dhfr locus were found while dhps-dhfr combined loci revealed 49 unique haplotypes. Prevalence of double, triple and quadruple mutations were common while 1 haplotype was found with all five mutated codons (F/AGEGS/T) at dhps locus. Detection of quadruple mutants (51I/59R/108N/164L) in the present study, earlier recorded from Car Nicobar Island, India only, indicates the presence of high levels of resistance to sulphadoxine/pyrimethamine in north-east India. Associations between resistant haplotypes and the clinical outcomes and emerging resistance in sulphadoxine/pyrimethamine in

The emerging antibiotic resistance genes in the aquatic environment have aroused public concern. As β-lactam is the most widely used group of antibiotics, β-lactam resistance genes were selected to investigate their distribution and diversity in the activated sludge from 15 geographically different sewage treatment plants (STPs) of China, Singapore, USA, and Canada. Specific PCR and quantitative real-time PCR (q-PCR) were used to investigate the occurrence and abundance of nine β-lactam resistance genes. Five genes (OXA-1, OXA-2, OXA-10, ampC, and TEM-1) were detected in most of the sludge collected, while three genes (mecA, CTX-M-1, and SME) were not found in any sludge sample. The total abundances of the six detected β-lactam resistance genes in the 15 STPs varied from 5.34 × 10(1) copies/ng DNA (ampC) to 5.49 × 10(4) copies/ng DNA (OXA-1). Overall, OXA-1 had the highest total concentration, followed by IMP and OXA-10. Noticeably, the abundances of TEM-1 in Chinese STPs were generally higher than those in the STPs of other countries, while the abundances of OXA-2 and IMP in the STPs of North America were much greater than those of East Asia. A total of 78 clones carrying β-lactam resistance genes were randomly selected from six clone libraries for phylogenetic diversity analysis; the similarity of these cloned genes to known β-lactam resistance genes with sequence identities ranged from 96% to 100%. Furthermore, OXA-1, ampC, and IMP were found to be more diverse than the other β-lactam resistance genes.

The Jurassic of North-East Greenland: Jurassic dinoflagellate cysts from Hochstetter Forland, North-East Greenland

Directory of Open Access Journals (Sweden)

Piasecki, Stefan

2004-11-01

Full Text Available Three sections in Hochstetter Forland, North-East Greenland, referred to the Jurassic Payer Dal and Bernbjerg Formations, have been analysed for dinoflagellate cysts. The dinoflagellate cysts,new finds of ammonites and previously recorded marine faunas form the basis for improved dating of the succession. The basal strata of the Payer Dal Formation at Kulhus is here dated as Late Callovian, Peltoceras athleta Chronozone, based on the presence of relatively abundant Limbicysta bjaerkei, Mendicodinium groenlandicum, Rhychoniopsis cladophora and Tubotuberella dangeardii in an otherwise poor Upper Callovian dinoflagellate assemblage. Ammoniteshave not been recorded from these strata. The upper Payer Dal Formation at Agnetesøelven is dated as Late Oxfordian, Amoeboceras glosense – Amoeboceras serratum Chronozones, based onthe presence of Sciniodinium crystallinum, together with Cribroperidinium granuligera and Stephanelytron sp. The age is in accordance with ammonites present in the uppermost part ofthe formation at Søndre Muslingebjerg. New ammonites in the Bernbjerg Formation at Agnetesøelven together with dinoflagellate cysts indicate an earliest Kimmeridgian age, Raseniacymodoce and Aulacostephanoides mutabilis Chronozones.The Upper Callovian dinoflagellate cysts from Hochstetter Forland belong to a local brackish to marginal marine assemblage, which only allows a fairly broad correlation to coeval assemblagesin central East Greenland. In contrast, the Oxfordian and Kimmeridgian assemblages are fully marine and can be correlated from Milne Land in central East Greenland via Hochstetter Forland to Peary Land in eastern North Greenland.

The U.S. Geological Survey (USGS) collaborated with the China Geological Survey (CGS) to conduct a mineral resource assessment of Mesozoic porphyry copper deposits in East Asia. This area hosts several very large porphyry deposits, exemplified by the Dexing deposit in eastern China that contains more than 8,000,000 metric tons of copper. In addition, large parts of the area are undergoing active exploration and are likely to contain undiscovered porphyry copper deposits.

Multifaceted intra-seasonal modes over the East Asia-western North Pacific summer monsoon region

Science.gov (United States)

Ha, K. J.; Oh, H.

2017-12-01

Intra-seasonal monsoon prediction is the most imperative task due to high impact on 2/3 of world populations' daily life, but there remains an enduring challenge in climate science. The present study aims to provide a physical understanding of the sources for prediction of dominant intra-seasonal modes in the East Asian-western North Pacific summer monsoon (EA-WNPSM): preMeiyu&Baiu, Changma&Meiyu, WNPSM, and monsoon gyre modes classified by the self-organizing map analysis. The preMeiyu-Baiu mode is strongly linked to both the anomalous low-level convergence and vertical wind shear through baroclinic instability, and the Changma&Meiyu mode has a strengthened tropic-subtropics connection along the western north Pacific subtropical high, which induces vertical destabilization and strong convective instability. The WNPSM and monsoon gyre modes are characterized by anomalous southeasterly flow of warm and moist air from western north Pacific monsoon, and low-level easterly flow, respectively. Prominent difference in response to the ENSO leads to different effects of the Indian Ocean and western Pacific thermal state, and consequently, the distinct moisture supply and instability variations for the EASM intra-seasonal modes. We attempt to determine the predictability sources for the four modes in the EA-WNPSM using physical-empirical model. The selected predictors are based on the persistent and tendency signals of the SST/2m air temperature and sea level pressure fields, which reflect the asymmetric response to the ENSO and the ocean and land surface anomalous conditions. For the preMeiyu&Baiu mode, the SST cooling tendency over the WNP, which persists into summer, is the distinguishing contributor which is causative of north-south thermal contrast. Since the Changma&Meiyu mode is strongly related to the WNP subtropical high, a major precursor is the persistent SST difference between the Indian Ocean and the western Pacific. The WNPSM mode is mostly affected by the

Hepatitis B epidemiology in Asia, the Middle East and Africa.

André, F

Asia and Africa have previously been classified as areas of high endemicity for hepatitis B virus (HBV), but in some countries highly effective vaccination programmes have shifted this pattern towards intermediate or low endemicity. Thus, China is now the only country in Asia where HBV endemicity is high. Countries with intermediate endemicity include India, Korea, the Philippines, Taiwan and Thailand, and those with low endemicity include Japan, Pakistan, Bangladesh, Singapore, Sri Lanka and Malaysia. Most countries in Africa have high HBV endemicity, with the exceptions of Tunisia and Morocco, which have intermediate endemicity. Zambia has borderline intermediate/high endemicity. In the Middle East, Bahrain, Iran, Israel and Kuwait are areas of low endemicity, Cyprus, Iraq and the United Arab Emirates have intermediate endemicity, and Egypt, Jordan, Oman, Palestine, Yemen and Saudi Arabia have high endemicity. All of these Middle East countries reach a large proportion of their population with hepatitis B vaccination, which is reducing the infection rate, particularly in Saudi Arabia. The vaccination programme in Taiwan has also greatly reduced the HBV infection rate. Future vaccination programmes must take into account the mode of transmission of HBV, the healthcare infrastructure to deliver vaccination, and the socioeconomic and political factors in each individual country, to determine the most cost-effective way of infection control.

Previous studies on the impacts of free trade agreements (FTAs) in East Asia have assumed full utilization of preferences. The evidence suggests that this assumption is seriously in error, with the estimated uptake particularly low in East Asia. In this paper, we assume a more realistic utilization rate in estimating impacts. We find that actual utilization rates significantly diminish the benefits from preferential liberalization, but in a non-linear way. Reciprocity is an important motivati...

Full Text Available This study was examined to reveal haplotype distribution and phylogenetic relationship using mitochondrial DNA CYTB gene sequences of Reeve’s turtle (Mauremys reevesii of East Asia. CYTB sequences of Reeve’s turtles were divided into 6 haplotypes (Hap01–Hap06. Chinese turtles were found in Hap01, Hap02, Hap04, and Hap05, and Hap01 was the highest frequency of 85.0%. Korean Turtles were found in Hap01, Hap03, Hap04, and Hap05, and Hap03 was the highest frequency of 52.1%. Although there was no haplotype which includes only the CYTB sequence exclusive for Reeve’s turtles of Korea, since no CYTB sequence of China was found in Hap03, it would be possible that Hap03 turtles of Korea are separated from those of China. The haplotypes of Reeve’s turtles of East Asia were monophyletic, which indicated that they had been evolved from a single maternal lineage, but went through local evolution after geographical migration and isolation in East Asia.

Winter to winter recurrence of atmospheric circulation anomalies over East Asia and its impact on winter surface air temperature anomalies.

Science.gov (United States)

Zhao, Xia; Yang, Guang

2017-01-01

The persistence of atmospheric circulation anomalies over East Asia shows a winter to winter recurrence (WTWR) phenomenon. Seasonal variations in sea level pressure anomalies and surface wind anomalies display significantly different characteristics between WTWR and non-WTWR years. The WTWR years are characterized by the recurrence of both a strong (weak) anomalous Siberian High and an East Asian winter monsoon over two successive winters without persistence through the intervening summer. However, anomalies during the non-WTWR years have the opposite sign between the current and ensuing winters. The WTWR of circulation anomalies contributes to that of surface air temperature anomalies (SATAs), which is useful information for improving seasonal and interannual climate predictions over East Asia and China. In the positive (negative) WTWR years, SATAs are cooler (warmer) over East Asia in two successive winters, but the signs of the SATAs are opposite in the preceding and subsequent winters during the non-WTWR years.

Building a new energy network in North East Asia. A perspective from post-Fukushima Japan

International Nuclear Information System (INIS)

Shibutani, Yu

2012-01-01

The accident at Fukushima Daiichi Nuclear Power Station (NPS) has accelerated Japan's drive for less dependence on nuclear and fossil energy and more green renewables, which inevitably require a new energy strategy. In this paper, a new strategic scenario for moving 'beyond a single economy' is proposed to incorporate Japan with the North East Asian (NEA) energy market in regards to its electricity grid and natural gas pipeline network while preserving nuclear power by strengthening safety. Suggestions are also made that Japan should open more doors for new comers in a manner of open-access towards member economies of NEA. However, there are persistent geopolitical constraints and risks in NEA. The connection of Japan's energy network to its regional neighbors would avoid the tendrils and tentacles of geopolitics that wrap around NEA, and subsequently provide opportunities to build on common energy interests.

Cancer is becoming the most important public health burden around the globe. As per the GLOBOCAN 2008 estimates, about 12.7 million cancer cases and 7.6 million cancer deaths were estimated to have occurred in 2008. The burden of cancer cases for India in the year 2020 is calculated to be 1,148,757 (male 534,353; female 614,404) compared to 979,786 in 2010. The pattern of cancer incidence is varying among geographical regions, esophageal cancer for example being high in China, lung cancer in USA, and gallbladder cancer in Chile. The question remains why? Is it due to the diversity in genome pool, food habits, risk factor association and role of genetic susceptibility or some other factors associated with it? In India, the North East (NE)-India region is seeing a marked increase in cancer incidence and deaths, with a very different cancer incidence pattern compared to mainland India. The genome pool of the region is also quite distinct from the rest of India. Northeastern tribes are quite distinct from other groups; they are more closely related to East Asians than to other Indians. In this paper an attempt was made to see whether there is any similarity among the pattern of cancer incidence cases for different sites of NE-India region to South or East-Asia. Principal Component Analysis (PCA), Hierarchical Cluster Analysis (HCA), Pearson Correlation coefficient test was assessed to evaluate the linkage of North-East India region to other regions. A p value NE-India with South and East-Asian regions, which may lead to the conclusion that there might be a genetic linkage between these regions.

Full Text Available Poverty is a multidimensional problem that the approach to eradicate poverty must also be multidimensional. The study aims to formulate a model of poverty alleviation in coastal fishing in the North Coast of East Java. Grounded research approach used to determine the causes, impacts and implications of poverty fishermen. The results showed that the main cause of poverty that occurred in the three districts in East Java's north coast is different from one another. In Gresik district, the major cause of poverty is law enforcements that do not support fishermen and overfishing. While Lamongan more due to low fish prices and capital problems. While in Tuban fishermen due to limited infrastructure and lazy and extravagant lifestyle of the fishermen. These differences lead to different coping strategies so that later can form a concept model of poverty alleviation North Coast fishermen in East Java.

Recently, the frequency and intensity of natural hazards have been increasing due to human-induced climate change. Because most damages of natural hazards over East Asia have been related to extreme precipitation events, it is important to estimate future change in extreme precipitation characteristics caused by climate change. We investigate future changes in extremal values of summer precipitation simulated by five regional climate models participating in the CORDEX-East Asia project (i.e., HadGEM3-RA, RegCM4, MM5, WRF, and GRIMs) over East Asia. 100-year return value calculated from the generalized extreme value (GEV) parameters is analysed as an indicator of extreme intensity. In the future climate, the mean values as well as the extreme values of daily precipitation tend to increase over land region. The increase of 100-year return value can be significantly associated with the changes in the location (intensity) and scale (variability) GEV parameters for extreme precipitation. It is expected that the results of this study can be used as fruitful references when making the policy of disaster management.

A study was made on the LP gas supply/demand in Asia including an outlook for 2000. Eleven countries in Asia including NIES countries, ASEAN countries, China and India have been continuing their rapid growth of economy and have rapidly been increasing their energy consumption. There, LP gas spreads as a home use fuel, and countries excluding some LP gas producing countries depend considerably upon the import from the Middle East. The LP gas consumption quantity is steadily increasing in China and India having huge population, etc., and dependence of LP gas is increasing upon LP gas producing countries of the Middle East. Nevertheless, in the Middle East, the domestic consumption of LP gas, mostly butane, is increasing. Namely, butane is used as raw material of MTBE, and LP gas as that of petroleum chemicals. The Middle East has a lot of plant projects of a sizable size in the future, which predicts that LP gas export from LP gas producing countries of the Middle East is decreasing. 2 refs., 62 figs., 57 tabs.

Population Genetic Structure and Evidence of Demographic Expansion of the Ayu (Plecoglossus altivelis in East Asia

Directory of Open Access Journals (Sweden)

2012-10-01

Full Text Available Plecoglossus altivelis (ayu is an amphidromous fish widely distributed in Northeastern Asia from the East China Sea to the northern Japanese coastal waters, encompassing the Korean Peninsula within its range. The shore lines of northeastern region in Asia have severely fluctuated following glaciations in the Quaternary. In the present study, we investigate the population genetic structure and historical demographic change of P. altivelis at a population level in East Asia. Analysis of molecular variance (AMOVA based on 244 mitochondrial control region DNA sequences clearly showed that as the sampling scope extended to a larger geographic area, genetic differentiation began to become significant, particularly among Northeastern populations. A series of hierarchical AMOVA could detect the genetic relationship of three closely located islands between Korea and Japan that might have been tightly connected by the regional Tsushima current. Neutrality and mismatch distribution analyses revealed a strong signature of a recent population expansion of P. altivelis in East Asia, estimated at 126 to 391 thousand years ago during the late Pleistocene. Therefore it suggests that the present population of P. altivelis traces back to its approximate demographic change long before the last glacial maximum. This contrasts our a priori expectation that the most recent glacial event might have the most crucial effect on the present day demography of marine organisms through bottleneck and subsequent increase of effective population size in this region.

Tephra (volcanic ash) layers have the potential to synchronise disparate palaeoenvironmental archives on regional to hemispheric scales. Highly productive arc regions, like those in East Asia, offer a considerable number of widespread isochrons, but before records can be confidently correlated using these layers, a refined and integrated framework of these eruptive events is required. Here we present the first high-resolution Holocene cryptotephra study in East Asia, using the Lake Suigetsu sedimentary archive in central Japan. The Holocene tephrostratigraphy has been extended from four to twenty ash layers using cryptotephra extraction techniques, which integrates the deposits from explosive eruptions from North Korea/China, South Korea and along the Japanese arc. This Lake Suigetsu tephrostratigraphy is now the most comprehensive record of East Asian volcanism, and the linchpin site for correlating sequences across this region. Major element glass geochemical compositions are presented for the tephra layers in the sequence, which have been compared to proximal datasets to correlate them to their volcanic source and specific eruptions. This study has significantly extended the ash dispersal of many key Holocene marker layers, and has identified the first distal occurrence of isochrons from Ulleungdo and Changbaishan volcanoes. Utilising the high-precision Lake Suigetsu chronology, we are able to provide constrained eruption ages for the tephra layers, which can be transferred into other site-specific age models containing these markers. This new framework indicates that several isochrons stratigraphically bracket abrupt climate intervals in Japan, and could be used to precisely assess the regional and hemispheric synchronicity of these events.

The modulation of Tibetan Plateau heating on the multi-scale northernmost margin activity of East Asia summer monsoon in northern China

Science.gov (United States)

Zhang, Jie; Liu, Chen; Chen, Haishan

2018-02-01

The northernmost margin of East Asian summer monsoon (EASM) could well reflect wet/dry climate variability in the EASM marginal zone (northern China). The study shows that EASM occurs in northern China from Meiyu period to midsummer, and it is also the advancing period of the northern margin of EASM (NMEASM) before the 43rd pentad. NMEASM activity exhibits multi-scale variability, at cycles of 2-3-yr, 4-6-yr and 9-12-yr, which respond not only to EASM intensity but also to westerly circulation anomaly, exhibiting the mid-latitude Eurasian waves and the high-latitude Eurasian teleconnection (EU) patterns. The positive anomalies of Silk Road pattern and EU pattern in recent two decades contribute to the enhanced west-ridge and east-trough anomaly around 120°E over northern China, leading to divergence of moisture flux and north wind anomaly, which is helpful for southward western pacific subtropical high (WPSH) and southward NMEASM. Negative Eurasian pattern along subtropical Jet leads to anticyclone anomaly over south of the Yangtze River, deep trough and north wind anomaly along the west coast of the subtropical Pacific, contributing to southward WPSH and NMEASM at the cycle of 4-6-yr. Remote forcing sources of these anomalous Eurasian waves include North Europe, north of Caspian Sea, Central Asia, Tibetan Plateau and the west of Lake Baikal; the south of Lake Baikal is a local forcing region. The Tibetan Plateau heating and snow cover could modulate Eurasian wave pattern at multi-scale, which could be used as prediction reference of multi-scale NMEASM.

Influences of the variation in inflow to East Asia on surface ozone over Japan during 1996–2005

Directory of Open Access Journals (Sweden)

2011-08-01

Full Text Available Air quality simulations in which the global chemical transport model CHASER and the regional chemical transport model WRF/chem are coupled have been developed to consider the dynamic transport of chemical species across the boundaries of the domain of the regional chemical transport model. The simulation captures the overall seasonal variations of surface ozone, but overestimates its concentration over Japanese populated areas by approximately 20 ppb from summer to early winter. It is deduced that ozone formation around Northeast China and Japan in summer is overestimated in the simulation. On the other hand, the simulation well reproduces the interannual variability and the long-term trend of observed surface ozone over Japan. Sensitivity experiments have been performed to investigate the influence of the variation in inflow to East Asia on the interannual variability and the long-term trend of surface ozone over Japan during 1996–2005. The inflow defined in this paper includes the recirculation of species with sources within the East Asian region as well as the transport of species with sources out of the East Asian region. Results of sensitivity experiments suggest that inflow to East Asia accounts for approximately 30 % of the increasing trend of surface ozone, whereas it has much less influence on the interannual variability of observed surface ozone compared to meteorological processes within East Asia.

The Rapid Arctic Warming and Its Impact on East Asian Winter Weather in Recent Decade

Science.gov (United States)

Kim, S. J.; Kim, B. M.; Kim, J. H.

2015-12-01

The Arctic is warming much more rapidly than the lower latitudes. In contrast to the rapid Arctic warming, in winters of the recent decade, the cold-air outbreaks over East Asia occur more frequently and stronger than in 1990s. By accompanying the snow over East Asia, the strong cold surges have led to a severe socio-economic impact. Such severe cold surges in recent decade over east Asia is consistent with the more dominant negative phase of the Arctic Oscillation (AO), that may be attributed by the Arctic amplification. In both observation-based reanalysis and numerical model experiments, the Arctic sea ice melting leads to the weakening of the AO polarity by reducing the meridional temperature gradient through a heat flux feedback. The Arctic warming and associated sea ice melting over the Kara-Barents area in late fall and early winter first release a lot of heat to the atmosphere from the ocean by a strong contrast in temperature and moisture and higher height anomaly is developed over the Kara/Barents and the Ural mountains The anomalous anticyclonic anomaly over the Arctic strengthen the Siberian High and at the same time the east Asian trough is developed over the western coast of the North Pacific. Through the passage between the margin of the Siberian High and east Asian tough, an extremely cold air is transported from east Siberia to east Asia for sometimes more than a week. Such a severe sold air brings about the moisture from nearby ocean, largely influencing the daily lives and economy in north East China, Korea, and Japan. The recent Arctic and associated sea ice melting is not only contributed to the local climate and weather, but also a severe weather in mid-latitudes through a modulation in polar vortex.

Polycyclic aromatic hydrocarbons (PAHs) are hazardous pollutants, with increasing emissions in pace with economic development in East Asia, but their distribution and fate in the atmosphere are not yet well understood. We extended the regional atmospheric chemistry model WRF-Chem (Weather Research Forecast model with Chemistry module) to comprehensively study the atmospheric distribution and the fate of low-concentration, slowly degrading semivolatile compounds. The WRF-Chem-PAH model reflects the state-of-the-art understanding of current PAHs studies with several new or updated features. It was applied for PAHs covering a wide range of volatility and hydrophobicity, i.e. phenanthrene, chrysene and benzo[a]pyrene, in East Asia. Temporally highly resolved PAH concentrations and particulate mass fractions were evaluated against observations. The WRF-Chem-PAH model is able to reasonably well simulate the concentration levels and particulate mass fractions of PAHs near the sources and at a remote outflow region of East Asia, in high spatial and temporal resolutions. Sensitivity study shows that the heterogeneous reaction with ozone and the homogeneous reaction with the nitrate radical significantly influence the fate and distributions of PAHs. The methods to implement new species and to correct the transport problems can be applied to other newly implemented species in WRF-Chem.

A comparative analysis between the relation of income distribution and economic regional integration in East Asia and Latin America

Full Text Available This paper analyses the relationship between inequality and de facto regional economic integration during the last two decades in Latin America and East Asia Pacific regions, focusing on intra-regional exports. Globalization has been considered as a driving of inequality, although export-led growth models are associated with high economic growth rates. Export-led growth models have been more dynamic in East Asia than in Latin America, through the development of supply chain networks of intermediate and final goods. Research questions explore the relation between inequality and patterns of de facto intra-regional trade. Empirical analysis uses a fixed effects panel data with Heteroskedasticity and Autocorrelation Consistent (HAC covariance matrix. Results showed that increments in regional intra-trade are associated with reductions of inequality, more in East Asia Pacific than in Latin America. The contribution of this paper is the introduction of intra-regional trade as a new factor that is negatively associated with inequality.

We have developed the Integrated Climate and Air Quality Modeling System (ICAMS) through the one-way nesting of global-regional models to examine the changes in the surface ozone concentrations over East Asia under future climate scenarios. Model simulations have been conducted for the present period of 1996-2005 to evaluate the performance of ICAMS. The simulated surface ozone concentrations reproduced the observed monthly mean concentrations at sites in East Asia with high R2 values (0.4-0.9), indicating a successful simulation to capture both spatial and temporal variability. We then performed several model simulations with the six IPCC SRES scenarios (A2, A1B, A1FI, A1T, B1, and B2) for the next three periods, 2016-2025 (the 2020s), 2046-2055 (the 2050s), and 2091-2100 (the 2090s). The model results show that the projected changes of the annual daily mean maximum eight-hour (DM8H) surface ozone concentrations in summertime for East Asia are in the range of 2-8 ppb, -3 to 8 ppb, and -7 to 9 ppb for the 2020s, the 2050s, and the 2090s, respectively, and are primarily determined based on the emission changes of NOx and NMVOC. The maximum increases in the annual DM8H surface ozone and high-ozone events occur in the 2020s for all scenarios except for A2, implying that the air quality over East Asia is likely to get worse in the near future period (the 2020s) than in the far future periods (the 2050s and the 2090s). The changes in the future environment based on IPCC SRES scenarios would also influence the change in the occurrences of high-concentrations events more greatly than that of the annual DM8H surface ozone concentrations. Sensitivity simulations show that the emissions increase is the key factor in determining future regional surface ozone concentrations in the case of a developing country, China, whereas a developed country, Japan would be influenced more greatly by effects of the regional climate change than the increase in emissions.

Forests play an important role in regional and global carbon (C) cycles. With extensive afforestation and reforestation efforts over the last several decades, forests in East Asia have largely expanded, but the dynamics of their C stocks have not been fully assessed. We estimated biomass C stocks of the forests in all five East Asian countries (China, Japan, North Korea, South Korea, and Mongolia) between the 1970s and the 2000s, using the biomass expansion factor method and forest inventory data. Forest area and biomass C density in the whole region increased from 179.78 × 10(6) ha and 38.6 Mg C ha(-1) in the 1970s to 196.65 × 10(6) ha and 45.5 Mg C ha(-1) in the 2000s, respectively. The C stock increased from 6.9 Pg C to 8.9 Pg C, with an averaged sequestration rate of 66.9 Tg C yr(-1). Among the five countries, China and Japan were two major contributors to the total region's forest C sink, with respective contributions of 71.1% and 32.9%. In China, the areal expansion of forest land was a larger contributor to C sinks than increased biomass density for all forests (60.0% vs. 40.0%) and for planted forests (58.1% vs. 41.9%), while the latter contributed more than the former for natural forests (87.0% vs. 13.0%). In Japan, increased biomass density dominated the C sink for all (101.5%), planted (91.1%), and natural (123.8%) forests. Forests in South Korea also acted as a C sink, contributing 9.4% of the total region's sink because of increased forest growth (98.6%). Compared to these countries, the reduction in forest land in both North Korea and Mongolia caused a C loss at an average rate of 9.0 Tg C yr(-1), equal to 13.4% of the total region's C sink. Over the last four decades, the biomass C sequestration by East Asia's forests offset 5.8% of its contemporary fossil-fuel CO2 emissions. © 2014 John Wiley & Sons Ltd.

2016-09-01

Full Text Available In order to understand impacts of global warming on dust aerosol over East Asia, a regional climate model (RegCM3 coupled with a dust model is employed to simulate the present (1991–2000, following the observed concentration of the greenhouse gases and future (2091–2100, following the A1B scenario dust aerosol. Three experiments are performed over East Asia at a horizontal resolution of 50 km, driven by the outputs from a global model of the Model for Interdisciplinary Research on Climate (MIROC3.2_hires, two without (Exp.1 for the present and Exp.2 for the future and one with (Exp.3 for the future the radiative effects of dust aerosols. Effects of climate changes on dust aerosols and the feedback of radiative effects in the future are investigated by comparing differences of Exp.2 and Exp.1, Exp.3 and Exp.2, respectively. Results show that global warming will lead to the increases of dust emissions and column burden by 2% and 14% over East Asia, characterized by the increase in December–January–February–March (DJFM and the decrease in April–May (AM. Similar variations are also seen in the projected frequencies of high dust emission events, showing an advanced active season of dust in the future. The net top-of-atmosphere (TOA radiative forcing is positive over the desert source regions and negative over downwind regions, while the surface radiative forcing is negative over the domain, which will lead to a reduction of dust emissions and column burden.

Full Text Available BACKGROUND: The burden of breast cancer in Asia is escalating. We evaluated the impact of ethnicity on survival after breast cancer in the multi-ethnic region of South East Asia. METHODOLOGY/PRINCIPAL FINDINGS: Using the Singapore-Malaysia hospital-based breast cancer registry, we analyzed the association between ethnicity and mortality following breast cancer in 5,264 patients diagnosed between 1990 and 2007 (Chinese: 71.6%, Malay: 18.4%, Indian: 10.0%. We compared survival rates between ethnic groups and calculated adjusted hazard ratios (HR to estimate the independent effect of ethnicity on survival. Malays (n = 968 presented at a significantly younger age, with larger tumors, and at later stages than the Chinese and Indians. Malays were also more likely to have axillary lymph node metastasis at similar tumor sizes and to have hormone receptor negative and poorly differentiated tumors. Five year overall survival was highest in the Chinese women (75.8%; 95%CI: 74.4%-77.3% followed by Indians (68.0%; 95%CI: 63.8%-72.2%, and Malays (58.5%; 95%CI: 55.2%-61.7%. Compared to the Chinese, Malay ethnicity was associated with significantly higher risk of all-cause mortality (HR: 1.34; 95%CI: 1.19-1.51, independent of age, stage, tumor characteristics and treatment. Indian ethnicity was not significantly associated with risk of mortality after breast cancer compared to the Chinese (HR: 1.14; 95%CI: 0.98-1.34. CONCLUSION: In South East Asia, Malay ethnicity is independently associated with poorer survival after breast cancer. Research into underlying reasons, potentially including variations in tumor biology, psychosocial factors, treatment responsiveness and lifestyle after diagnosis, is warranted.

East Asia has experienced rapid development with increasing carbon monoxide (CO) emission in the past decades. Therefore, uplifting CO from the boundary layer to the free troposphere in East Asia can have great implications on regional air quality around the world. It can also influence global climate due to the longer lifetime of CO at higher altitudes. In this study, three cases of high CO episodes in the East China Sea and the Sea of Japan from 2003 to 2005 are examined with spaceborne Measurements of Pollution in the Troposphere (MOPITT) data, in combination with aircraft measurements from the Measurement of Ozone and Water Vapor by Airbus In-Service Aircraft (MOZAIC) program. Through analyses of the simulations from a chemical transport model GEOS-Chem and a trajectory dispersion model FLEXPART, we found different CO signatures in the elevated CO and distinct transport pathways and mechanisms for these cases.

Fragmented Production in East Asia: What are Their Implications for the Sino-U.S. Trade

Full Text Available Fragmented production means organization of production in which different stages of production are divided among different suppliers that are located in different countries. East Asia is one of the most important manufacturing centers in the world, China imports components from other East Asian economies for processing and then exports to the United States. The volume of export from China to the United States increase in traditional international trade statistics. Therefore, the solution of Sino-U.S. trade imbalance should pay attention to the relationship between the United States, China, and other East Asian economies.

The Steel and Shipbuilding Industries of South Korea: Rising East Asia and Globalization

Directory of Open Access Journals (Sweden)

Kyoung-ho Shin

2015-08-01

Full Text Available In this paper, we focus on the roles of the steel and shipbuilding industries as generative sectors in Korea’s rapid economic ascent. We argue that a world-systems analysis focusing on these generative sectors provides a more complete understanding of Korea’s rapid economic ascent than do other theoretical models. We outline the similarities between this case and those analyzed by Bunker and Ciccantell (2005, 2007 both in terms of the central role of generative sectors in raw materials and transport industries and how the creation and growth of these two industrial sectors shaped institutional patterns and the broader economic ascent of South Korea and East Asia. Even though South Korea has not and may never become a challenger for global hegemony, its rapid ascent has helped reshape East Asia and the capitalist world-economy. We use the model of generative sectors to analyze the critical industries that underlay and shaped South Korea’s ascent from a low wage, light industry base to a world leader in electronics, automobiles, and other advanced industries.

Multi-scale model analysis of boundary layer ozone over East Asia

Directory of Open Access Journals (Sweden)

M. Lin

2009-05-01

Full Text Available This study employs the regional Community Multiscale Air Quality (CMAQ model to examine seasonal and diurnal variations of boundary layer ozone (O₃ over East Asia. We evaluate the response of model simulations of boundary layer O₃ to the choice of chemical mechanisms, meteorological fields, boundary conditions, and model resolutions. Data obtained from surface stations, aircraft measurements, and satellites are used to advance understanding of O₃ chemistry and mechanisms over East Asia and evaluate how well the model represents the observed features. Satellite measurements and model simulations of summertime rainfall are used to assess the impact of the Asian monsoon on O₃ production. Our results suggest that summertime O₃ over Central Eastern China is highly sensitive to cloud cover and monsoonal rainfall over this region. Thus, accurate simulation of the East Asia summer monsoon is critical to model analysis of atmospheric chemistry over China. Examination of hourly summertime O₃ mixing ratios from sites in Japan confirms the important role of diurnal boundary layer fluctuations in controlling ground-level O₃. By comparing five different model configurations with observations at six sites, the specific mechanisms responsible for model behavior are identified and discussed. In particular, vertical mixing, urban chemistry, and dry deposition depending on boundary layer height strongly affect model ability to capture observed behavior. Central Eastern China appears to be the most sensitive region in our study to the choice of chemical mechanisms. Evaluation with TRACE-P aircraft measurements reveals that neither the CB4 nor the SAPRC99 mechanisms consistently capture observed behavior of key photochemical oxidants in springtime. However, our analysis finds that SAPRC99 performs somewhat better in simulating mixing ratios of H₂O₂ (hydrogen peroxide

2018-03-01

Full Text Available The paper presents the current state of autonomous energy sources in the north of the Far East. Consideration is given to the capacity structures with a focus on industrial and residential autonomous energy sources. One of the main problems facing power supply to residential consumers in the north of the Far East is the insufficiently developed transport infrastructure, which causes complicated fuel delivery patterns, fuel price rise, and hence high electricity generation cost. The changes in the installed capacity of renewable energy sources (RES in the north of the Far East are demonstrated for the period between 2011 and 2015. The research shows the main directions of power production diversification in the north of the Far East. The directions include the use of local fuel types, the development of cogeneration, the involvement of renewable energy sources and small-scale nuclear power plants. The paper presents a forecast for the renewable energy development in the north of the Far East up to 2035, made by the authors. The priority RES projects in the off-grid power supply in the north of the Far East are wind and solar power plants

Interannual Rainfall Variability in North-East Brazil: Observation and Model Simulation

Science.gov (United States)

Harzallah, A.; Rocha de Aragão, J. O.; Sadourny, R.

1996-08-01

The relationship between interannual variability of rainfall in north-east Brazil and tropical sea-surface temperature is studied using observations and model simulations. The simulated precipitation is the average of seven independent realizations performed using the Laboratoire de Météorologie Dynamique atmospheric general model forced by the 1970-1988 observed sea-surface temperature. The model reproduces very well the rainfall anomalies (correlation of 091 between observed and modelled anomalies). The study confirms that precipitation in north-east Brazil is highly correlated to the sea-surface temperature in the tropical Atlantic and Pacific oceans. Using the singular value decomposition method, we find that Nordeste rainfall is modulated by two independent oscillations, both governed by the Atlantic dipole, but one involving only the Pacific, the other one having a period of about 10 years. Correlations between precipitation in north-east Brazil during February-May and the sea-surface temperature 6 months earlier indicate that both modes are essential to estimate the quality of the rainy season.

Regulatory infrastructure in East and West Asia: Present status and perspectives

International Nuclear Information System (INIS)

2001-01-01

A detailed assessment carried out by the IAEA showed that five Member States in East Asia (Bangladesh, Mongolia, Myanmar, Sri Lanka, Vietnam) and nine Member States in West Asia (Jordan, Kazakhstan, Lebanon, Qatar, Saudi Arabia, Syria, United Arab Emirates, Uzbekistan, Yemen) did not have an adequate radiation and waste safety infrastructure in general and a basic regulatory infrastructure in particular. This indicated the partial or complete lack of control of radiation sources, i.e. location, identification, registration, licensing and inspection. Since 1996, these countries have been participating in the Model Project on Upgrading Radiation and Waste Safety Infrastructure with the primary objective of establishing or upgrading their basic regulatory infrastructure. The results achieved in the establishment/upgrading of this infrastructure and the follow-up and extension to other Member States are presented in this paper. (author)

2018-02-01

Full Text Available We present a 3-D climatology of the desert dust distribution over South and East Asia derived using CALIPSO (Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation data. To distinguish desert dust from total aerosol load we apply a methodology developed in the framework of EARLINET (European Aerosol Research Lidar Network. The method involves the use of the particle linear depolarization ratio and updated lidar ratio values suitable for Asian dust, applied to multiyear CALIPSO observations (January 2007–December 2015. The resulting dust product provides information on the horizontal and vertical distribution of dust aerosols over South and East Asia along with the seasonal transition of dust transport pathways. Persistent high D_AOD (dust aerosol optical depth values at 532 nm, of the order of 0.6, are present over the arid and semi-arid desert regions. Dust aerosol transport (range, height and intensity is subject to high seasonality, with the highest values observed during spring for northern China (Taklimakan and Gobi deserts and during summer over the Indian subcontinent (Thar Desert. Additionally, we decompose the CALIPSO AOD (aerosol optical depth into dust and non-dust aerosol components to reveal the non-dust AOD over the highly industrialized and densely populated regions of South and East Asia, where the non-dust aerosols yield AOD values of the order of 0.5. Furthermore, the CALIPSO-based short-term AOD and D_AOD time series and trends between January 2007 and December 2015 are calculated over South and East Asia and over selected subregions. Positive trends are observed over northwest and east China and the Indian subcontinent, whereas over southeast China trends are mostly negative. The calculated AOD trends agree well with the trends derived from Aqua MODIS (Moderate Resolution Imaging Spectroradiometer, although significant differences are observed over specific regions.

The dispersal of Homo sapiens across southern Asia: how early, how often, how complex?

Science.gov (United States)

Dennell, Robin; Petraglia, Michael D.

2012-07-01

The timing and the paths of colonization of southern Asia by Homo sapiens are poorly known, though many population geneticists, paleoanthropologists, and archaeologists have contended that this process began with dispersal from East Africa, and occurred between 60,000 and 40,000 years ago. However, the evidence for this scenario is very weak, particularly the lack of human skeletal evidence between the Levant and Borneo before 40 ka, and other explanations are possible. Here we argue that environmental and archaeological information is increasingly indicating the likelihood that H. sapiens exited Africa much earlier than commonly thought, and may have colonized much of southern Asia well before 60,000 years ago. Additionally, we cannot exclude the possibility that several dispersal events occurred, from both North and East Africa, nor the likelihood that early populations of H. sapiens in southern Asia interbred with indigenous populations of Neanderthals, Denisovans and Homo erectus. The population history of southern Asia during the Upper Pleistocene is likely far more complex than currently envisaged.

Predictable patterns of the May-June rainfall anomaly over East Asia

Science.gov (United States)

Xing, Wen; Wang, Bin; Yim, So-Young; Ha, Kyung-Ja

2017-02-01

During early summer (May-June, MJ), East Asia (EA) subtropical front is a defining feature of Asian monsoon, which produces the most prominent precipitation band in the global subtropics. Here we show that dynamical prediction of early summer EA (20°N-45°N, 100°E-130°E) rainfall made by four coupled climate models' ensemble hindcast (1979-2010) yields only a moderate skill and cannot be used to estimate predictability. The present study uses an alternative, empirical orthogonal function (EOF)-based physical-empirical (P-E) model approach to predict rainfall anomaly pattern and estimate its potential predictability. The first three leading modes are physically meaningful and can be, respectively, attributed to (a) the interaction between the anomalous western North Pacific subtropical high and underlying Indo-Pacific warm ocean, (b) the forcing associated with North Pacific sea surface temperature (SST) anomaly, and (c) the development of equatorial central Pacific SST anomalies. A suite of P-E models is established to forecast the first three leading principal components. All predictors are 0 month ahead of May, so the prediction here is named as a 0 month lead prediction. The cross-validated hindcast results demonstrate that these modes may be predicted with significant temporal correlation skills (0.48-0.72). Using the predicted principal components and the corresponding EOF patterns, the total MJ rainfall anomaly was hindcasted for the period of 1979-2015. The time-mean pattern correlation coefficient (PCC) score reaches 0.38, which is significantly higher than dynamical models' multimodel ensemble skill (0.21). The estimated potential maximum attainable PCC is around 0.65, suggesting that the dynamical prediction models may have large rooms to improve. Limitations and future work are discussed.

The air quality over Northeast Asia have been deteriorated for decades due to high population and energy use in the region. Despite of more stringent air pollution control policies by the governments, air quality over the region seems not been improved as much - even worse sometimes. The needs of more scientific understanding of inter-relationship among emissions, transport, chemistry over the region are much higher to effectively protect public health and ecosystems. Two aircraft filed campaigns targeting year 2016, MAPS-Seoul and KORUS-AQ, have been organized to study the air quality of over Korea and East Asia relating to chemical evolution, emission inventories, trans-boundary contribution, and satellite application. We developed a new East-Asia emissions inventory, named KORUS2015, based on NIER/KU-CREATE (Comprehensive Regional Emissions inventory for Atmospheric Transport Experiment), in support of the filed campaigns. For anthropogenic emissions, it has 54 fuel classes, 201 sub-sectors and 13 pollutants, including CO2, SO2, NOx, CO, NMVOC, NH3, PM10, and PM2.5. Since the KORUS2015 emissions framework was developed using the integrated climate and air quality assessment modeling framework (i.e. GAINS) and is fully connected with the comprehensive emission processing/modeling systems (i.e. SMOKE, KU-EPS, and MEGAN), it can be effectively used to support atmospheric field campaigns for science and policy. During the field campaigns, we are providing modeling emissions inventory to participating air quality models, such as CMAQ, WRF-Chem, CAMx, GEOS-Chem, MOZART, for forecasting and post-analysis modes. Based on initial assessment of those results, we are improving our emissions, such as VOC speciation, biogenic VOCs modeling. From the 2nditeration between emissions and modeling/measurement, further analysis results will be presented at the conference.

Summertime land-sea thermal contrast and atmospheric circulation over East Asia in a warming climate—Part I: Past changes and future projections

Science.gov (United States)

Kamae, Youichi; Watanabe, Masahiro; Kimoto, Masahide; Shiogama, Hideo

2014-11-01

Land-sea surface air temperature (SAT) contrast, an index of tropospheric thermodynamic structure and dynamical circulation, has shown a significant increase in recent decades over East Asia during the boreal summer. In Part I of this two-part paper, observational data and the results of transient warming experiments conducted using coupled atmosphere-ocean general circulation models (GCMs) are analyzed to examine changes in land-sea thermal contrast and the associated atmospheric circulation over East Asia from the past to the future. The interannual variability of the land-sea SAT contrast over the Far East for 1950-2012 was found to be tightly coupled with a characteristic tripolar pattern of tropospheric circulation over East Asia, which manifests as anticyclonic anomalies over the Okhotsk Sea and around the Philippines, and a cyclonic anomaly over Japan during a positive phase, and vice versa. In response to CO2 increase, the cold northeasterly winds off the east coast of northern Japan and the East Asian rainband were strengthened with the circulation pattern well projected on the observed interannual variability. These results are commonly found in GCMs regardless of future forcing scenarios, indicating the robustness of the East Asian climate response to global warming. The physical mechanisms responsible for the increase of the land-sea contrast are examined in Part II.

Full Text Available This work aims at characterising the seamount physiography and biology in the OSPAR Convention limits (north-east Atlantic Ocean and Mediterranean Sea. We first inferred potential abundance, location and morphological characteristics of seamounts, and secondly, summarized the existing biological, geological and oceanographic in situ research, identifying examples of well-studied seamounts. Our study showed that the seamount population in the OSPAR area (north-east Atlantic and in the Mediterranean Sea is large with around 557 and 101 seamount-like features, respectively. Similarly, seamounts occupy large areas of about 616 000 km2 in the OSPAR region and of about 89 500 km2 in the Mediterranean Sea. The presence of seamounts in the north-east Atlantic has been known since the late 19th century, but overall knowledge regarding seamount ecology and geology is still relatively poor. Only 37 seamounts in the OSPAR area (3.5% of all seamounts in the region, 22 in the Mediterranean Sea (9.2% of all seamounts in the region and 25 in the north-east Atlantic south of the OSPAR area have in situ information. Seamounts mapped in both areas are in general very heterogeneous, showing diverse geophysical characteristics. These differences will likely affect the biological diversity and production of resident and associated organisms.

Full Text Available Magnetic data provides basic information for geological and geophysical interpretation. In this study we compile recently collected (57 cruises survey and old (published and open access magnetic data. This compilation includes land, marine and aeromagnetic data acquired in the East Asia region. The newly acquired magnetic data are mainly concentrated mainly in the South China Sea (SCS (especially in the northern continental shelf, the northwestern part of the West Philippine Basin (WPB, and the East China Sea. The updated magnetic dataset is gridded with a spacing of one arc-minute. The new magnetic map provides new insights into the tectonic setting of East Asia. Analysis of the compiled data reveals several regional anomaly patterns: (1 the NE-SW trending high positive magnetic anomaly zone extending from southwest Taiwan to the area about 114.5°E114.5°E and 22°N22°N is pronounced; but it is less continuous southwest of the Penghu islands. In addition, the orientation of this high linear magnetic zone changes slightly in 118.5°E,118.5°E, 22.5°N22.5°N from N60°EN60°E - N50°E.N50°E. (2 Between the Gagua Ridge (GR and the Luzon-Okinawa Fracture Zone (LOFZ the marine magnetic stripes of the WPB exhibit a NW-SE orientation. This suggests that the seafloor spreading could be related to the first stage of the WPB east of the LOFZ. (3 The Urdaneta and Amami plateaus are associated with high magnetization zones. These high magnetization zones extend northwestward and are subducting beneath the Ryukyu Trench.

Due to lack of reliable proxies from the Westerlies-dominant region, the strength change of Northern Hemisphere Westerlies remains poorly understood. The aim of this study is to provide a reliable paleoclimatic proxy about the Northern Hemisphere Westerlies change. Here we report a 30.7 m thick loess section from the Ili basin directly controlled by the Westerlies. Based on optically stimulated luminescence (OSL) and high resolution grain-size records, we reconstruct the change history of the Westerlies strength during the last glacial period (mainly Marine Isotope Stages 2, MIS2), being similar with the Westerlies index recorded in the Qinghai Lake sediments. Within error limits, all ages are in stratigraphic order. We further compare the climatic records among the Ili loess, Qinghai Lake and the NGRIP, their similarity shows a good climatic coupling relationship among the Central Asia, East Asia and the North Atlantic, and the Westerlies plays a critical influence in transporting the North Atlantic signal to Central and East Asia.

Evaluation of aerosol optical properties of GEOS-Chem over East Asia during the DRAGON-Asia 2012 campaign

A nested version of 3-D chemical transport model (GEOS-Chem v9-01-02) is evaluated over East Asia during the Distributed Regional Aerosol Gridded Observation Networks (DRAGON)-Asia 2012 campaign period, focusing on fine-mode aerosol optical depth (fAOD) and single scattering albedo (SSA). Both are important to assess the effect of anthropogenic aerosols on climate. We compare the daily mean simulated optical properties of aerosols with the observations from DRAGON-Asia campaign for March-May, 2012 (provided in level 2.0: cloud screened and quality assured). We find that the model reproduces the observed daily variability of fAOD (R=0.67), but overestimates the magnitude by 30%, which is in general consistent with other global model comparisons from ACCMIP. However, a significant high bias in the model is found compared to the observed SSA at 440 nm, which is important for determining the sign of aerosol radiative forcing. In order to understand causes for this gap we conduct several sensitivity tests by changing source magnitudes and input parameters of aerosols, affecting the aerosol optical properties under various atmospheric conditions, which allows us to reduce the gap and to find the optimal values in the model.

Whither the TPP? Political Economy of Ratification and Effect on Trade Architecture in East Asia

Directory of Open Access Journals (Sweden)

Byung-il Choi

2016-09-01

Full Text Available In the race for establishing trading architecture consistent with new landscape of the global economy, the US is ahead of the game by concluding the Trans Pacific Partnership Agreement with 11 countries. To make it reality, the ratification is essential. In the battle for ratification in the US, declining globalism confronts rising protectionism. This paper models the ratification process as contest between globalism and protectionism, and analyzes the optimal timing for ratification. Based on this framework, various ratification scenarios are analyzed. The paper argues less likelihood for the lame-duck session passage and more likelihood for prolonged and protracted delay, due to changing political dynamics and declining intellectual support for globalism. Hence, the future of Trans Pacific Partnership Agreement may prove different, compared to the North American Free Trade Agreement and the Korea-US Free Trade Agreement, both of which were renegotiated and ratified eventually. Then, the US would lose the first move advantage. The paper also discusses strategic implications of delayed ratification on the evolution of trading architecture in East Asia.

Evaluation and uncertainties of global climate models as simulated in East Asia and China

International Nuclear Information System (INIS)

Zhao, Z.C.

1994-01-01

The assessments and uncertainties of the general circulation models (GCMs) as simulated in East Asia and China (15-60 N, 70-140 E) have been investigated by using seven GCMs. Four methods of assessment have been chosen. The variables for the validations for the GCMs include the annual, seasonal and monthly mean temperatures and precipitation. The assessments indicated that: (1) the simulations of seven GCMs for temperature are much better than those for precipitation; (2) the simulations in winter are much better than those in summer; (3) the simulations in eastern parts are much better than those in Western parts for both temperature and precipitation; (4) the best GCM for simulated temperature is the GISS model, and the best GCM for simulated precipitation is the UKMO-H model. The seven GCMs' means for both simulated temperature and precipitation provided good results. The range of uncertainties in East Asia and China due to human activities are presented. The differences between the GCMs for temperature and precipitation before the year 2050 are much smaller than those after the year 2050

The Role of Stigma and Denormalization in Suicide-Prevention Laws in East Asia: A Sociocultural, Historical, and Ethical Perspective.

Science.gov (United States)

Chen, Justin A; Courtwright, Andrew; Wu, Kevin Chien-Chang

In many Western countries, the criminalization and stigmatization of suicide has given way to a biomedical approach aimed at destigmatizing suicide and treating underlying mental illness. By contrast, in many East Asian countries, suicide has never historically been criminalized or stigmatized. High rates of suicide in Japan, South Korea, and Taiwan have recently led policy makers in those countries to pursue innovative suicide-prevention strategies. The intentional denormalization of harmful behaviors has been discussed in the public health and ethics literatures, particularly with regard to smoking cessation, and could represent a novel mechanism for preventing suicides in East Asia. Using examples from the sociocultural, historical, and legal discourses surrounding suicide in Western and East Asian contexts, we suggest that denormalization can be a justified, culturally relevant suicide-prevention strategy, but that care must be taken to avoid shaming or stigmatizing suicidal individuals. Specifically, we propose the term weak denormalization to refer to an ethically permissible strategy at the mildest end of a spectrum of denormalizing approaches-milder than the reintegrative shaming described in the criminal justice literature, and diametrically opposed to outright stigmatization, which is generally considered ethically impermissible. Given the severe stigma of mental illness in East Asia, adopting the dominant Western view of suicide as solely a psychiatric concern would not be justified. Weak denormalization strategies in East Asia should be culturally tailored and rigorously tested on a small scale. They should include social supports, praise for the bravery of those of who seek help, and strategies to reduce shame regarding perceived social failure.

East Asia is the major atmospheric mercury (Hg) source region in the world due to the excessive coal combustion, industrial emission, and biomass burning in this area. Nonetheless, studies concerning the export of atmospheric Hg from East Asia are still limited. Accordingly, atmospheric Hg has been measured at various sites in Taiwan to study its temporal and spatial distribution, and the significance of long-range transport from the East Asian continent as well. Here we report the data collected in Fu-guei-jiao (121.97°E, 25.47°N, ~30 m a.s.l.), Mt. Bamboo (121.54°E, 25.19°N, 1025 m a.s.l.), and Lulin Atmospheric Background Station (LABS; 120.87°E, 23.47°N, 2862 m a.s.l.) to discuss the atmospheric Hg export from the East Asian continent. Twenty-four hour-integrated total atmospheric Hg (THg) samples were manually collected in Fu-guei-jiao and Mt. Bamboo in 2007-2008 and quantified by dual amalgamation CVAFS. On the other hand, continuous measurements of gaseous elemental Hg (GEM), reactive gaseous Hg (RGM), and particulate Hg (PHg) at LABS began since April 13, 2006 using the Tekran 2537A/1130/1135 speciation system. Mean(±S.D.) THg concentrations were 2.09±0.71 and 1.86±0.50 ng m-3 for Fu-guei-jiao and Mt. Bamboo, respectively. At LABS between April 2006 and April 2009, the mean(±S.D.) concentrations of GEM, RGM and PHg were 1.77±0.54 ng m-3, 22.4±43.8 pg m-3 and 6.3±10.9 pg m-3, respectively. Evident seasonal distribution in THg/GEM concentrations was observed at all sites with higher values usually occurred between fall and spring when the air masses were mainly from the East Asian continent, indicating the influence of the East Asian atmospheric Hg outflow. This also demonstrated that the atmospheric Hg export is occurring both in the boundary layer and in the free troposphere. Concentrations of PHg were usually low at LABS; however, elevated values were detected in spring when the Indochina Peninsula biomass burning plumes frequently affected

Stressors including regional climate change, economic development effects upon land use and an increasing demand for food production have resulted in significant impacts on the dryland ecosystems in the East Asia (DEA) region. Ecosystem services, such as its provisional services in providing forage for grazing as well as its functional services in regulating water and carbon fluxes, have been significantly altered over the past three decades. Conversely, changes in the landscape, particularly land cover types, have also been blamed for intensified climatic events such as dust storms and severe and frequent droughts within the region. The interactive nature of climate, ecosystems and society is complex and not fully understood, making it difficult, if not impossible, to develop effective adaptation strategies for the region. A special synthesis workshop on ‘Dryland Ecosystems in East Asia: State, Changes, Knowledge Gaps, and Future’ was held from 18–20 July 2011 in Kaifeng, Henan Province, China, with the aim of identifying knowledge gaps, quantifying impacts and developing a future research agenda for the region. The specific objectives of this workshop were to answer some key socio-environmental questions, including the following. (1) What do we know about the drylands in DEA? (2) What are the knowledge gaps? (3) What are the solutions to these issues? This paper provides a synthesis of the workshop consensus and findings on the state of knowledge and challenges in addressing these science issues for the DEA region. (letter)

2013-11-01

Full Text Available There is as much abundance of archaeological heritage in East Asia as there is diversity in the methodology for its reconstruction and representation. The Re-relic program in China recognizes the uniqueness of archaeological heritage in East Asia and has developed a tailored virtual reconstruction methodology that is both scientifically robust and popular for public interpretation. The theoretical consideration and field experience over the years shall contribute to the global understanding of the value and technique in virtual reconstruction, while testifying to the very principles of Seville Charter.

An intense summer dust storm over East Asia during June 24-27, 2010, was systematically analyzed using the Weather Research and Forecasting model coupled with Chemistry (WRF-Chem) and a variety of in situ measurements and satellite retrievals. The results showed that the WRF-Chem model captured the spatial and temporal distributions of meteorological factors and dust aerosols over East Asia. This summer dust storm was initiated by the approach of a transverse trough in the northwestern Xinjiang. Because of the passage of the cutoff-low, a large amount of cold air was transported southward and further enhanced in the narrow valleys of the Altai and Tianshan Mountains, which resulted in higher wind speeds and huge dust emissions over the Taklimakan Desert (TD). Dust emission fluxes over the TD were as high as 54 μg m-2 s-1 on June 25th. The dust aerosols from the TD then swept across Inner Mongolia, Ningxia and Mongolia, and some were also transported eastward to Beijing, Tianjin, the Hebei region, and even South Korea and Japan. The simulations further showed that summer dust over East Asia exerts an important influence on the radiation budget in the Earth-atmosphere system. Dust heat the atmosphere at a maximum heating rate of 0.14 k day-1, effectively changing the vertical stability of the atmosphere and affecting climate change at regional and even global scales. The dust event-averaged direct radiative forcing induced by dust particles over the TD at all-sky was -6.0, -16.8 and 10.8 W m-2 at the top of the atmosphere, the surface, and in the atmosphere, respectively.

To provide an integrative review of literature on health communication in East Asia and detail culturally-specific influences. Using PRISMA model, search of PubMed, PsychInfo, Web of Knowledge, ERIC and CINAHL databases were conducted for studies between January 2000 and March 2017, using the terms 'clinician/health professional-patient', 'nurse/doctor-patient, 'communication' and 'Asia'. 38 studies were included: Mainland China, Hong Kong, Japan, South Korea, and Taiwan. The existing body of research on clinician patient communication in East Asia can be classified: 1) understanding the roles and expectations of the nurse, clinician, patient, and family in clinician-patient consultations: a) nurse-patient communication; b) doctor-patient communication; c) the role of family member; and 2) factors affecting quality of care: d) cultural attitudes towards death and terminal illnesses; e) communication preferences affecting trust, decision-making and patient satisfaction; f) the extent to which patient centred care is being implemented in practice; and g) communication practices in multilingual/multi-disciplinary environments. The review detailed the complexity and heterogeneity of clinician-patient communication across East Asia. The studies reviewed indicate that research in East Asia is starting to move beyond a preference for Western-based communication practices. There is a need to consider local culture in understanding and interpreting medical encounters in East Asia. The paper highlights the need for a specific culturally-appropriate model of health communication in East Asia which may significantly improve relationships between clinicians and patients.

Andreasen, Arne Døssing; Dahl-Jensen, T.; Thybo, Hans

2008-01-01

The combined Greenland-Senja Fracture Zones (GSFZ) represent a first-order plate tectonic feature in the North Atlantic Ocean. The GSFZ defines an abrupt change in the character of magnetic anomalies with well-defined seafloor spreading anomalies in the Greenland and Norwegian basins to the south...... but ambiguous and weak magnetic anomalies in the Boreas Basin to the north. Substantial uncertainty exists concerning the plate tectonic evolution of the latter area, including the role of the East Greenland Ridge, which is situated along the Greenland Fracture Zone. In 2002, a combined ocean-bottom seismometer...

Economic analysis of milk production and consumption in the Middle East and North Africa

Mansoor Maitah

2012-01-01

Full Text Available Milk products are considered as the essential food commodities for humans. Milk products contain essential elements for the human body such as protein, glucose, minerals and vitamins. Moreover, milk is considered the cheapest source of animal protein, an important resource for some related transformation industries and provides employment opportunities for a large number of small producers in both rural and urban areas. The aim of this paper is to analyze the factors which determine the supply and demand for liquid milk (henceforth milk in the Middle East and North Africa in order to point out the main problems and constraints obstructing the milk production in this region. The research also attempts to understand the drivers for the development in milk production in the Middle East and North Africa.Total milk production in the Middle East and North Africa increased from about 12.57 million tons in 1990 to about 25.18 millions tons in 2008. This paper attempts to identify the factors which influence the effectiveness of production, consumption and foreign trade of milk in the Middle East and North Africa. The most important factors affecting consumption is the population, per capita income and produced quantity where a 1% increase in all of them results in increasing the quantity consumed by 1.3%, 2.86% and 0.611%, respectively. Milk sector provides employment opportunities for more than 25% of the working force in some Middle East and North Africa countries.

Woessner, J.; Nyst, M.; Seyhan, E.

2015-12-01

The last decade has tragically shown the social and economic vulnerability of countries in South-East Asia to earthquake hazard and risk. While many disaster mitigation programs and initiatives to improve societal earthquake resilience are under way with the focus on saving lives and livelihoods, the risk management sector is challenged to develop appropriate models to cope with the economic consequences and impact on the insurance business. We present the source model and ground motions model components suitable for a South-East Asia earthquake risk model covering Indonesia, Malaysia, the Philippines and Indochine countries. The source model builds upon refined modelling approaches to characterize 1) seismic activity from geologic and geodetic data on crustal faults and 2) along the interface of subduction zones and within the slabs and 3) earthquakes not occurring on mapped fault structures. We elaborate on building a self-consistent rate model for the hazardous crustal fault systems (e.g. Sumatra fault zone, Philippine fault zone) as well as the subduction zones, showcase some characteristics and sensitivities due to existing uncertainties in the rate and hazard space using a well selected suite of ground motion prediction equations. Finally, we analyze the source model by quantifying the contribution by source type (e.g., subduction zone, crustal fault) to typical risk metrics (e.g.,return period losses, average annual loss) and reviewing their relative impact on various lines of businesses.

The countries of the South East Asia region, which includes Bangladesh, Bhutan, Pakistan, Korea, India, Indonesia, Maldives, Myanmar, Nepal, Sri Lanka, and Thailand, have undertaken a variety of strategies to address the health challenges in the region. The ever-growing pressure of population in the region has allowed rapid transmission of communicable diseases like malaria, tuberculosis (TB), leprosy, and HIV/AIDS. One of the innovative community-based health initiatives in response to this problem is Indonesia's Primary Health Care Project. This project aimed to develop a sustainable health infrastructure by training medical staff, coordinators, village cadres, midwives and those working for TB programs; provision of ongoing guidance and education in this area; and provision of medicines and funds. The project has pioneered a process towards positive changes. Another strategy is the collaboration of youth groups, island development committees, and health workers in Maldives which has led to the declaration of two islands (Madifushi and Haa Alif Berinmadhoo) as 'no smoking' islands. In addition, Sarvodaya has successfully developed a methodology to involve Buddhist monks in AIDS prevention and control through "the Buddhist approach to AIDS prevention in Sri Lanka."

Phylogeography of Quercus variabilis based on chloroplast DNA sequence in East Asia: multiple glacial refugia and Mainland-migrated island populations.

Full Text Available The biogeographical relationships between far-separated populations, in particular, those in the mainland and islands, remain unclear for widespread species in eastern Asia where the current distribution of plants was greatly influenced by the Quaternary climate. Deciduous Oriental oak (Quercus variabilis is one of the most widely distributed species in eastern Asia. In this study, leaf material of 528 Q. variabilis trees from 50 populations across the whole distribution (Mainland China, Korea Peninsular as well as Japan, Zhoushan and Taiwan Islands was collected, and three cpDNA intergenic spacer fragments were sequenced using universal primers. A total of 26 haplotypes were detected, and it showed a weak phylogeographical structure in eastern Asia populations at species level, however, in the central-eastern region of Mainland China, the populations had more haplotypes than those in other regions, with a significant phylogeographical structure (N(ST= 0.751> G(ST= 0.690, P<0.05. Q. variabilis displayed high interpopulation and low intrapopulation genetic diversity across the distribution range. Both unimodal mismatch distribution and significant negative Fu's F(S indicated a demographic expansion of Q. variabilis populations in East Asia. A fossil calibrated phylogenetic tree showed a rapid speciation during Pleistocene, with a population augment occurred in Middle Pleistocene. Both diversity patterns and ecological niche modelling indicated there could be multiple glacial refugia and possible bottleneck or founder effects occurred in the southern Japan. We dated major spatial expansion of Q. variabilis population in eastern Asia to the last glacial cycle(s, a period with sea-level fluctuations and land bridges in East China Sea as possible dispersal corridors. This study showed that geographical heterogeneity combined with climate and sea-level changes have shaped the genetic structure of this wide-ranging tree species in East Asia.

A brief preliminary analysis of the economic feasibility of regional fuel cycle centres in South and South-East Asia is presented. The indicative break-even costs and break-even plant sizes for the various fuel cycle services are estimated and the timing for their establishment on the basis of IAEA and ESCAP nuclear power projections in the region are shown. The paper discusses the need for achieving regional self-sufficiency for nuclear fuel services and suggests that a detailed study should be undertaken by the IAEA in close co-operation with the countries of the region to find out their requirements for nuclear fuel services.

Han, Zhiwei; Ueda, Hiromasa; Sakurai, Tatsuya

A regional air quality model (RAQM) has been developed and applied together with an aerosol model to investigate the states and characteristics of wet deposition in East Asia in December 2001. Model simulation is performed with monthly based emission inventory [Streets, D.G., Bond, T.C., Carmichael, G.R., Fernandes, S.D., Fu, Q., He, D., Klimont, Z., Nelson, S. M., Tsai, N.Y., Wang, M.Q., Woo, J.-H., Yarber, K.F., 2003. An inventory of gaseous and primary emissions in Asia in the year 2000. Journal of Geophysical Research 108(D21), 8809] and meteorological fields derived from MM5. Model results are compared with extensive monitoring data including relevant gaseous species and ions in precipitation. The validation demonstrates that this model system is able to represent most of the major physical and chemical processes involved in acid deposition and reproduces concentrations reasonably well, within a factor of 2 of observations in general. The study shows that the regions with pH less than 4.5 are mainly located in southwestern China, parts of the Yangtze Delta, the Yellow Sea and the Korean peninsula, indicating wide regions of acid precipitation in East Asia in wintertime. Japan islands mainly exhibit pH values of 4.5-5.0, whereas over wide areas of northern China, pH values are relatively high (⩾5.0) due to neutralization by alkaline materials such as calcium-laden particles and ammonia, which are more abundant in northern China than that in southern China. While acid rain over most of China is still characterized by sulfur-induced type, considerable areas of eastern China and the western Pacific Rim are found to be more affected by nitric acid than sulfuric acid in acidification of precipitation, which is supposed to result from a combined effect of variations in photochemistry and emission, suggesting the increasing importance of NO x emission in these regions.

Mitochondrial DNA transit between West Asia and North Africa inferred from U6 phylogeography

Directory of Open Access Journals (Sweden)

Larruga José M

2003-10-01

Full Text Available Abstract Background World-wide phylogeographic distribution of human complete mitochondrial DNA sequences suggested a West Asian origin for the autochthonous North African lineage U6. We report here a more detailed analysis of this lineage, unraveling successive expansions that affected not only Africa but neighboring regions such as the Near East, the Iberian Peninsula and the Canary Islands. Results Divergence times, geographic origin and expansions of the U6 mitochondrial DNA clade, have been deduced from the analysis of 14 complete U6 sequences, and 56 different haplotypes, characterized by hypervariable segment sequences and RFLPs. Conclusions The most probable origin of the proto-U6 lineage was the Near East. Around 30,000 years ago it spread to North Africa where it represents a signature of regional continuity. Subgroup U6a reflects the first African expansion from the Maghrib returning to the east in Paleolithic times. Derivative clade U6a1 signals a posterior movement from East Africa back to the Maghrib and the Near East. This migration coincides with the probable Afroasiatic linguistic expansion. U6b and U6c clades, restricted to West Africa, had more localized expansions. U6b probably reached the Iberian Peninsula during the Capsian diffusion in North Africa. Two autochthonous derivatives of these clades (U6b1 and U6c1 indicate the arrival of North African settlers to the Canarian Archipelago in prehistoric times, most probably due to the Saharan desiccation. The absence of these Canarian lineages nowadays in Africa suggests important demographic movements in the western area of this Continent.

Ha Yong-Chool

2013-06-01

Full Text Available The purpose of this short paper is to introduce a new concept and way of thinking about the future of Northeast Asia in conjunction with the development of Russian Far East and Eastern Siberia. The basic arguments of this paper are: first, the specialists should shed the conventional definition of geographical boundaries, especially in defining Northeast Asia; second, Russia’s Far Eastern development can make a significant contribution to the regional community building depending on how creatively and imaginatively the development proceeds; lastly, it is high time to start preparation for the future of Northeast Asia before it gets too late. In this regard, at the end of this paper the authors introduce their initial effort to establish a consortium, the purpose of which is to lay groundwork for the establishment of an institute for Northeast Asian community building

Tracing the origin of the east-west population admixture in the Altai region (Central Asia.

Mercedes González-Ruiz

Full Text Available A recent discovery of Iron Age burials (Pazyryk culture in the Altai Mountains of Mongolia may shed light on the mode and tempo of the generation of the current genetic east-west population admixture in Central Asia. Studies on ancient mitochondrial DNA of this region suggest that the Altai Mountains played the role of a geographical barrier between West and East Eurasian lineages until the beginning of the Iron Age. After the 7th century BC, coinciding with Scythian expansion across the Eurasian steppes, a gradual influx of East Eurasian sequences in Western steppes is detected. However, the underlying events behind the genetic admixture in Altai during the Iron Age are still unresolved: 1 whether it was a result of migratory events (eastward firstly, westward secondly, or 2 whether it was a result of a local demographic expansion in a 'contact zone' between European and East Asian people. In the present work, we analyzed the mitochondrial DNA lineages in human remains from Bronze and Iron Age burials of Mongolian Altai. Here we present support to the hypothesis that the gene pool of Iron Age inhabitants of Mongolian Altai was similar to that of western Iron Age Altaians (Russia and Kazakhstan. Thus, this people not only shared the same culture (Pazyryk, but also shared the same genetic east-west population admixture. In turn, Pazyryks appear to have a similar gene pool that current Altaians. Our results further show that Iron Age Altaians displayed mitochondrial lineages already present around Altai region before the Iron Age. This would provide support for a demographic expansion of local people of Altai instead of westward or eastward migratory events, as the demographic event behind the high population genetic admixture and diversity in Central Asia.

Temporal correlation between opiate seizures in East/Southeast Asia and B.C. heroin deaths: a transoceanic model of heroin death risk.

Science.gov (United States)

McLean, Mark E

2003-01-01

Because heroin supply changes cannot be measured directly, their impact on populations is poorly understood. British Columbia has experienced an injection drug use epidemic since the 1980s that resulted in 2,590 illicit drug deaths from 1990-1999. Since previous work indicates heroin seizures can correlate with supply and B.C. receives heroin only from Southeast Asia, this study examined B.C. heroin deaths against opiate seizures in East/Southeast Asia. Opiate seizures in East/Southeast Asia and data from two B.C. mortality datasets containing heroin deaths were examined. The Pearson correlation coefficient for seizures against each mortality dataset was determined. Opiate seizures, all illicit drug deaths and all opiate deaths concurrently increased twice and decreased twice from 1989-1999, and all reached new peak values in 1993. Three B.C. sub-regions exhibited illicit drug deaths rate trends concurrent with the three principal datasets studied. The Pearson correlation coefficient for opiate-induced deaths against opiate seizures from 1980-1999 was R=0.915 (popiate seizures from 1987-1999 was R=0.896 (popiate seizures in East/Southeast Asia were very strongly correlated with B.C. opiate and illicit drug deaths. The number of B.C. heroin-related deaths may be strongly linked to heroin supply. Enforcement services are not effective in preventing harm caused by heroin in B.C.; therefore, Canada should examine other methods to prevent harm. The case for harm reduction is strengthened by the ineffectiveness of enforcement and the unlikelihood of imminent eradication of heroin production in Southeast Asia.

The neglected tropical diseases (NTDs), which affect the very poor, pose a major public health problem in the South-East Asia Region of the World Health Organization (WHO). Although more than a dozen NTDs affect the region, over the past five years four of them in particular - leprosy, lymphatic filariasis, visceral leishmaniasis (kala-azar) and yaws - have been targeted for elimination. These four were selected for a number of reasons. First, they affect the WHO South-East Asia Region disproportionately. For example, every year around 67% of all new leprosy cases and 60% of all new cases of visceral leishmaniasis worldwide occur in countries of the region, where as many as 850 million inhabitants are at risk of contracting lymphatic filariasis. In addition, several epidemiological, technological and historical factors that are unique to the region make each of these four diseases amenable to elimination. Safe and effective tools and interventions to achieve these targets are available and concerted efforts to scale them up, singly or in an integrated manner, are likely to lead to success. The World Health Assembly and the WHO Regional Committee, through a series of resolutions, have already expressed regional and global commitments for the elimination of these diseases as public health problems. Such action is expected to have a quick and dramatic impact on poverty reduction and to contribute to the achievement of the Millennium Development Goals. This paper reviews the policy rationale for disease control in the WHO South-East Asia Region, the progress made so far, the lessons learnt along the way, and the remaining challenges and opportunities.

Asia, which is characterized by monsoon climate and intense human activities, is one of the prominent understudied regions in terms of terrestrial carbon budgets and mechanisms of carbon exchange. To better understand terrestrial carbon cycle in Asia, we initiated multi-model and data intercomparison project in Asia (Asia-MIP). We analyzed outputs from multiple approaches: satellite-based observations (AVHRR and MODIS) and related products, empirically upscaled estimations (Support Vector Regression) using eddy-covariance observation network in Asia (AsiaFlux, CarboEastAsia, FLUXNET), ~10 terrestrial biosphere models (e.g. BEAMS, Biome-BGC, LPJ, SEIB-DGVM, TRIFFID, VISIT models), and atmospheric inversion analysis (e.g. TransCom models). We focused on the two difference temporal coverage: long-term (30 years; 1982-2011) and decadal (10 years; 2001-2010; data intensive period) scales. The regions of covering Siberia, Far East Asia, East Asia, Southeast Asia and South Asia (60-80E, 10S-80N), was analyzed in this study for assessing the magnitudes, interannual variability, and key driving factors of carbon cycles. We will report the progress of synthesis effort to quantify terrestrial carbon budget in Asia. First, we analyzed the recent trends in Gross Primary Productivities (GPP) using satellite-based observation (AVHRR) and multiple terrestrial biosphere models. We found both model outputs and satellite-based observation consistently show an increasing trend in GPP in most of the regions in Asia. Mechanisms of the GPP increase were analyzed using models, and changes in temperature and precipitation play dominant roles in GPP increase in boreal and temperate regions, whereas changes in atmospheric CO2 and precipitation are important in tropical regions. However, their relative contributions were different. Second, in the decadal analysis (2001-2010), we found that the negative GPP and carbon uptake anomalies in 2003 summer in Far East Asia is one of the largest

What explains high plant richness in East Asia? Time and diversification in the tribe Lysimachieae (Primulaceae).

What causes the disparity in biodiversity among regions is a fundamental question in biogeography, ecology, and evolutionary biology. Evolutionary and biogeographic processes (speciation, extinction, dispersal) directly determine species richness patterns, and can be studied using integrative phylogenetic approaches. However, the strikingly high richness of East Asia relative to other Northern Hemisphere regions remains poorly understood from this perspective. Here, for the first time, we test two general hypotheses (older colonization time, faster diversification rate) to explain this pattern, using the plant tribe Lysimachieae (Primulaceae) as a model system. We generated a new time-calibrated phylogeny for Lysimachieae (13 genes, 126 species), to estimate colonization times and diversification rates for each region and to test the relative importance of these two factors for explaining regional richness patterns. We find that neither time nor diversification rates alone explain richness patterns among regions in Lysimachieae. Instead, a new index that combines both factors explains global richness patterns in the group and their high East Asian biodiversity. Based on our results from Lysimachieae, we suggest that the high richness of plants in East Asia may be explained by a combination of older colonization times and faster diversification rates in this region. © 2018 The Authors.

Key Issues on Nuclear Energy Non-proliferation in East Asia

Hwang, Yong Soo; Whang, Joo Ho; Lee, Un Chul

2005-01-01

Energy demand in East Asia casts a significant challenge to sustainable economy development and socio-political stability in the region which has experienced tensions throughout the history. The energy demand in this region has been dramatically increased since the start of reform in PRC. DPRK is another challenge. The current electricity consumption in DPRK is around 10% of that in ROK. If the economy of PRC continuously grows to the level of neighboring states and if the living standard of DPRK reaches that of ROK, the energy and electricity demand in the region will certainly be out of control unless the proper measures are taken into actions from today. The only feasible energy option is the nuclear one. PRC already proclaimed its ambitious plan to deploy more than 30 reactors in the near future. In addition, a couple of the South Eastern Asian states expressed their willingness to introduce nuclear power plants in the future. The increase in the use of nuclear energy is expected to bring up the nuclear renaissance in the region. However, without the proper mechanisms to supply fresh fuels and to manage spent nuclear fuels with full compliance of nuclear energy nonproliferation, the new development will inevitably cause the instability in the region. So far many interesting proposals on nuclear cooperation in East Asia were announced. Unfortunately, none of them works out properly yet, partly because the old proposals were too political. To restart the engine of the nuclear cooperation and nonproliferation in the region, it is necessary to find out what would be the common interests of the region not so much related to politics. In this paper, some key technical issues are addressed for future regional joint studies

Foot-and-mouth disease virus (FMDV) is a highly contagious and genetically variable virus. Sporadic introductions of this virus into FMD-free countries may cause outbreaks with devastating consequences. In 2010 and 2011, incursions of the FMDV O/SEA/Mya-98 strain, normally restricted to countries in mainland Southeast Asia, caused extensive outbreaks across East Asia. In this study, 12 full genome FMDV sequences for representative samples collected from the People's Republic of China (PR China) including the Hong Kong Special Administrative Region (SAR), the Republic of Korea, the Democratic People's Republic of Korea, Japan, Mongolia and The Russian Federation were generated and compared with additional contemporary sequences from viruses within this lineage. These complete genomes were 8119 to 8193 nucleotides in length and differed at 1181 sites, sharing a nucleotide identity ≥ 91.0% and an amino acid identity ≥ 96.6%. An unexpected deletion of 70 nucleotides within the 5'-untranslated region which resulted in a shorter predicted RNA stem-loop for the S-fragment was revealed in two sequences from PR China and Hong Kong SAR and five additional related samples from the region. Statistical parsimony and Bayesian phylogenetic analysis provide evidence that these outbreaks in East Asia were generated by two independent introductions of the O/SEA/Mya-98 lineage sometime between August 2008 and March 2010. The rapid emergence of these viruses from Southeast Asia highlights the importance of adopting approaches to closely monitor the spread of this lineage that now poses a threat to livestock industries in other regions.

The Internationalization and Market Competition of Tsai Yueh-Hsun’s Post-Confucian TV Drama and Films in East Asia

2018-04-01

Full Text Available This essay investigates the East Asia-oriented TV and film productions of Taiwanese producer-director Tsai Yueh-hsun. His productions have made wide use of the transnational bankability of Taiwanese TV stars. Set in nationally non-specific urban societies, they are categorized as post-Confucian TV dramas, adopting liberal Western values and presenting problems in the authoritative patriarchal culture of the modern yet Confucian East Asia. They have competed in this market with neo-Confucian Korean and mainland Chinese TV dramas that follow Confucian patriarchal values. His productions in the 2000s entered many East Asian markets, including Southeast Asian countries, Japan, and mainland China, with the latter airing censored versions. In the 2010s, his productions have prioritized the rapidly increasing mainland Chinese market among all East Asian markets and adopted Taiwanese-mainland Chinese cooperation. The productions maintain the post-Confucian style of presentation, but remove the political viewpoint commonly perceived in Taiwan. Confronted with Taiwanese skepticism toward the Taiwanese-mainland Chinese cooperation, Tsai argues that this strategy will contribute to the development of Taiwan’s film and TV industry. The presentation of Taiwan’s modern places in the productions will help promote its tourism.

Full Text Available In this paper we propose to highlight the tourism evolution and its intensity in the North-East region of Romania, compared to two regions with similar touristic potential from the Eastern European Union: Subcarpathia from Poland and Central Slovakia. We analysed if the EU attachment of Romania, Poland, and Slovakia had some effects on tourism development in the three regions mentioned. Issues arising from the analysis of the current situation of tourism will allow us to draw some sustainable development directions of tourism in the North-East region based on conserving and capitalizing the uniqueness of the area. We will consider the experience of the other two regions, trying to adapt them to the situation of the North-East region. Based on the analysis we have made, we consider that other countries can inspire us by authorities’ initiatives in supporting tourism, good human resources training, entrepreneurship stimulation, and assistance in accessing financial resources, including EU ones.

The loess record of Central Asia provides an important archive of regional climate and environmental changes. In contrast to the widely investigated loess deposits in the Chinese Loess Plateau, Central Asian loess-paleosol sequences remain poorly understood. Here, we present an aeolian loess section in the southern Ili Basin. Based on granularity and mineralogical analyses, we reconstruct climatic changes during the last glaciation. The results indicated that most of the abrupt climatic events (such as Dansgaard-Oeschger events and Heinrich events) were imprinted in this loess section, although their amplitudes and ages showed some differences. Compared with the millennial oscillations recoded in loess and stalagmites in East Asia, the arid Central Asia responded more sensitively to the warming events than to the cooling events. The shifting trajectory of westerlies across Central Asia played an important role in dust deposition during the stadials. The North Atlantic climatic signals may have been transmitted from Central Asia to the East Asian monsoon regions via the westerlies.

Seasonal, interannual, and long-term variabilities in biomass burning activity over South Asia.

The seasonal, interannual, and long-term variations in biomass burning activity and related emissions are not well studied over South Asia. In this regard, active fire location retrievals from the Moderate Resolution Imaging Spectroradiometer (MODIS), the retrievals of aerosol optical depth (AOD) from MODIS Terra, and tropospheric column NO2 from Ozone Monitoring Instrument (OMI) are used to understand the effects of biomass burning on the tropospheric pollution loadings over South Asia during 2003-2013. Biomass burning emission estimates from Global Fire Emission Database (GFED) and Global Fire Assimilation System (GFAS) are also used to quantify uncertainties and regional discrepancies in the emissions of carbon monoxide (CO), nitrogen oxide (NOx), and black carbon (BC) due to biomass burning in South Asia. In the Asian continent, the frequency of fire activity is highest over Southeast Asia, followed by South Asia and East Asia. The biomass burning activity in South Asia shows a distinct seasonal cycle that peaks during February-May with some differences among four (north, central, northeast, and south) regions in India. The annual biomass burning activity in north, central, and south regions shows an increasing tendency, particularly after 2008, while a decrease is seen in northeast region during 2003-2013. The increase in fire counts over the north and central regions contributes 24 % of the net enhancement in fire counts over South Asia. MODIS AOD and OMI tropospheric column NO2 retrievals are classified into high and low fire activity periods and show that biomass burning leads to significant enhancement in tropospheric pollution loading over both the cropland and forest regions. The enhancement is much higher (110-176 %) over the forest region compared to the cropland (34-62 %) region. Further efforts are required to understand the implications of biomass burning on the regional air quality and climate of South Asia.

Fifteen chemistry-transport models are used to quantify, for the first time, the export of oxidised nitrogen (NOy) to and from four regions (Europe, North America, South Asia, and East Asia), and to estimate the uncertainty in the results. Between 12 and 24% of the NOx emitted is exported from each region annually. The strongest impact of each source region on a foreign region is: Europe on East Asia, North America on Europe, South Asia on East Asia, and East Asia on North America. Europe exports the most NOy, and East Asia the least. East Asia receives the most NOy from the other regions. Between 8 and 15% of NOx emitted in each region is transported over distances larger than 1000 km, with 3-10% ultimately deposited over the foreign regions. (authors)

The interaction of politics and ecology in the quest for sustainable development in South East Asia is explored in this book by contributors who provide a broad range of perspectives. In the first of the four main sections, the political context of ecological change is examined. The topics discussed are: Indonesia and Thailand in a globalising pulp and paper industry; environmental organisations and different political contexts in Malaysia, Indonesia and Vietnam; Japan and South East Asia's environment. Some of the processes and forms of human-induced environmental change are illustrated in the second section. These include: the search for sustainable livelihoods in Indonesian transmigration settlements; the 210 MW hydro-power project on the Theun river in Laos which illustrates the tensions between environmental costs and potential economic benefits; forest management in Laos. Discussion of the various methods which strengthen understanding of human-induced environmental change in the region is integrated with further illustrations of its process and context in the third section where the following are considered: environmental change in Malaysian Borneo; the value of remote sensing and geographical information systems in mapping the environment; the weakness of Vietnam's tropical forestry action plan. In the final section, an examination of some of the options for change which are necessary if sustainable development is to become a reality includes: the sustainability of ecotourism in Indonesia; the potential stewardship role of the Bajau people in Indonesia's proposed marine parks; environmental degradation, non-timber forest products and Iban communities in Sarawak; conservation and development in Brunei's rainforests; Philippine community-based forest management.

Middle Eastern and North African countries are undergoing nutrition transition, a transition which is associated with an increased burden of non-communicable diseases. This necessitates the evaluation of dietary patterns in these regions. The present study aimed to assess changes in dietary patterns in Middle Eastern and North African countries between 1961 and 2007. Availability of energy and fifteen main food items during 1961-2007 was examined using FAO food balance sheets from the FAOSTAT database. Fifteen countries including nine in the Middle East and six in North Africa were selected and the average availability of total energy and different food items in these regions were compared. Over the 47 years studied, energy and food availability (apart from animal fats and alcoholic beverages) has increased in the Middle East and North Africa. In both regions the proportion of energy derived from meat and vegetable oils has increased significantly while that from cereals decreased significantly. In addition, the proportion of energy from milk and dairy products and vegetables has shown an ascending trend in North Africa while the proportion of energy from fruits has shown a descending trend in the Middle East. The study results reveal an unfavourable trend towards a Westernized diet in the Middle East and, to a certain extent, in North Africa. Tailored nutritional education encouraging healthy eating for prevention of the burden of chronic diseases in these countries seems essential.

The North East Department is a resource-limited region of Haiti. Health care is provided by hospitals and community clinics, with no formal Emergency Medical System and undefined emergency services. As a paucity of information exists on available emergency services in the North East Department of Haiti, the objective of this study was to assess systematically the existing emergency care resources in the region. This cross-sectional observational study was carried out at all Ministry of Public Health and Population (MSPP)-affiliated hospitals in the North East Department and all clinics within the Fort Liberté district. A modified version of the World Health Organization (WHO) Tool for Situational Analysis to Assess Emergency and Essential Surgical Care and Generic Essential Emergency Equipment Lists were completed for each facility. Three MSPP hospitals and five clinics were assessed. Among hospitals, all had a designated emergency ward with 24 hour staffing by a medical doctor. All hospitals had electricity with backup generators and access to running water; however, none had potable water. All hospitals had x-ray and ultrasound capabilities. No computed tomography scanners existed in the region. Invasive airway equipment and associated medications were not present consistently in the hospitals' emergency care areas, but they were available in the operating rooms. Pulse oximetry was unavailable uniformly. One hospital had intermittently functioning defibrillation equipment, and two hospitals had epinephrine. Basic supplies for managing obstetrical and traumatic emergencies were available at all hospitals. Surgical services were accessible at two hospitals. No critical care services were available in the region. Clinics varied widely in terms of equipment availability. They uniformly had limited emergency medical equipment. The clinics also had inconsistent access to basic assessment tools (sphygmomanometers 20% and stethoscopes 60%). A protocol for transferring

South and East Asia are a particularly fast developing world economic areas, and are becoming increasingly more economically integrated. These countries, however, are not homogenous, and are lacking in any supra - national Authority. The total fiscal pressure of South and East Asian countries looks somewhat low when compared to that of countries with a similar per-capita income, pertaining to other economic world areas. However, a smooth Wagner law is confirmed by the data so that fiscal pres...

In contrast to Europe and North America, air pollution in Asia is increasing rapidly, resulting in both local air quality problems and higher acidic depositions. In 1989, an east-west group of scientists initiated a multi-institutional research project on Acid Rain and Emissions Reduction in Asia, funded for the past two years by the World Bank and the Asian Development Bank. Phase I, covering 23 countries of Asia, focused on the development of PC-based software called the Regional Air Pollution Information and Simulation Model (RAINS-ASIA). A 94-region Regional Energy Scenario Generator was developed to create alternative energy/emission scenarios through the year 2020. A long-range atmospheric transport model was developed to calculate dispersion and deposition of sulfur, based upon emissions from area and large point sources, on a one-degree grid of Asia. The resulting impacts of acidic deposition on a variety of vegetation types were analyzed using the critical loads approach to test different emissions management strategies, including both energy conservation measures and sulfur abatement technologies. 14 refs., 7 figs

Batrachochytrium dendrobatidis (Bd) is the pathogen responsible for chytridiomycosis, a disease that is associated with a worldwide amphibian population decline. In this study, we predicted the potential distribution of Bd in East and Southeast Asia based on limited occurrence data. Our goal was to design an effective survey area where efforts to detect the pathogen can be focused. We generated ecological niche models using the maximum-entropy approach, with alleviation of multicollinearity and spatial autocorrelation. We applied eigenvector-based spatial filters as independent variables, in addition to environmental variables, to resolve spatial autocorrelation, and compared the model's accuracy and the degree of spatial autocorrelation with those of a model estimated using only environmental variables. We were able to identify areas of high suitability for Bd with accuracy. Among the environmental variables, factors related to temperature and precipitation were more effective in predicting the potential distribution of Bd than factors related to land use and cover type. Our study successfully predicted the potential distribution of Bd in East and Southeast Asia. This information should now be used to prioritize survey areas and generate a surveillance program to detect the pathogen.

This study describes the effect of pollution transport between East Asia and South Asia on tropospheric ozone (O3) using model results from the Task Force on Hemispheric Transport of Air Pollution (TF HTAP). Ensemble mean O3 concentrations are evaluated against satellite-data and ground observations of surface O3 at four stations in India. Although modeled surface O3 concentrations are 1020ppb higher than those observed, the relative magnitude of the seasonal cycle of O3 is reproduced well. Using 20% reductions in regional anthropogenic emissions, we quantify the seasonal variations in pollution transport between East Asia and South Asia. While there is only a difference of 0.05 to 0.1ppb in the magnitudes of the regional contributions from one region to the other, O3 from East Asian sources affects the most densely populated parts of South Asia while Southern Asian sources only partly affect the populated parts of East Asia. We show that emission changes over East Asia between 2000 and 2010 had a larger impact on populated parts of South Asia than vice versa. This study will help inform future decisions on emission control policy over these regions. Copyright © 2015 Elsevier B.V. All rights reserved.

Rapid decline in carbon monoxide emissions and export from East Asia between years 2005 and 2016

Measurements of Pollution in the Troposphere (MOPITT) satellite and ground-based carbon monoxide (CO) measurements both suggest a widespread downward trend in CO concentrations over East Asia during the period 2005–2016. This negative trend is inconsistent with global bottom-up inventories of CO emissions, which show a small increase or stable emissions in this region. We try to reconcile the observed CO trend with emission inventories using an atmospheric inversion of the MOPITT CO data that estimates emissions from primary sources, secondary production, and chemical sinks of CO. The atmospheric inversion indicates a ~ ‑2% yr‑1 decrease in emissions from primary sources in East Asia from 2005–2016. The decreasing emissions are mainly caused by source reductions in China. The regional MEIC inventory for China is the only bottom up estimate consistent with the inversion-diagnosed decrease of CO emissions. According to the MEIC data, decreasing CO emissions from four main sectors (iron and steel industries, residential sources, gasoline-powered vehicles, and construction materials industries) in China explain 76% of the inversion-based trend of East Asian CO emissions. This result suggests that global inventories underestimate the recent decrease of CO emission factors in China which occurred despite increasing consumption of carbon-based fuels, and is driven by rapid technological changes with improved combustion efficiency and emission control measures.

Several intercomparison exercises were organised by the International Atomic Energy Agency (IAEA) on the determination of operational quantities at the regional or inter-regional basis. In East Asia region, a third phase of the intercomparison finished in mid 2004. It was organised within the frame of the Regional Cooperation Agreement (RCA) as a follow-up to previous exercises carried out during 1990-1992 and 1995-1996. The results of this intercomparison for the determination of operational quantities were satisfactory for all Member States. The laboratories demonstrated a good performance in quantities tested. The purpose of this paper is to present the results of the RCA/IAEA intercomparison and the future of RCA activities in support of assessment of occupational exposure by organising intercomparison runs.

The French nuclear policy. A model for security policy in North-East Asia

International Nuclear Information System (INIS)

Choe, K.

1998-01-01

Between the end of the second world war and the collapse of the Berlin wall, the French diplomacy was based on the nuclear policy in a solid and coherent way. This nuclear policy was an 'incarnation' of the national security conception, allowing France to recover its political, military and economical rank on the international scene. The most important characteristic of the French nuclear policy concerns the commercialization of the nuclear energy which aims to ensuring the national security through the building up of a financial, technological and political 'reserve'. In front of the domination of the USA and USSR during the cold war era, NE Asia had a similar geostrategic configuration as Western Europe. It concerns in particular the massive application of nuclear energy for both military and industrial purposes. The bases of the security policy in this region refers to the real use of the nuclear weapon by the USA against Japan in 1945. The French nuclear policy may be considered as a model for the building of the security policy of NE Asia, in particular through the commercialization of the nuclear technology between the countries in concern. This nuclear approach would allow the countries of these region to change their present day national defense policy into an economical and military cooperation. (J.S.)

A roaring trade? The legal trade in Panthera leo bones from Africa to East-Southeast Asia.

The African lion is the only big cat listed on CITES Appendix II, and the only one for which international commercial trade is legal under CITES. The trade in lion body parts, and especially the contentious trade in bones from South Africa to Asia, has raised concerns spanning continents and cultures. Debates were amplified at the 2016 CITES Conference of the Parties (CoP17) when a proposal to up-list lions to Appendix I was not supported and a compromise to keep them on Appendix II, with a bone trade quota for South Africa, was reached instead. CoP17 underscored a need for further information on the lion bone trade and the consequences for lions across the continent. Legal international trade in bones to Asia, allegedly to supply the substitute 'tiger bone' market, began in South Africa in February 2008 when the first CITES permits were issued. It was initially unclear the degree to which bones were sourced from captive-origin lions, and whether trade was a threat to wild lion populations. Our original assessment of the legal CITES-permitted lion bone trade from South Africa to East-Southeast Asia was for the period 2008-2011 (published 2015). In this paper, we consolidate new information that has become available for 2012-2016, including CITES reports from other African countries, and data on actual exports for three years to 2016 supplied by a freight forwarding company. Thus, we update the figures on the legal trade in lion bones from Africa to East-Southeast Asia in the period 2008-2016. We also contextualise the basis for global concerns by reviewing the history of the trade and its relation to tigers, poaching and wildlife trafficking. CITES permits issued to export bones escalated from ±314y-1 skeletons from 2008-2011, to ±1312y-1 skeletons from 2013-2015. South Africa was the only legal exporter of bones to Asia until 2013 when Namibia issued permits to export skeletons to Vietnam. While CITES permits to export ±5363 skeletons from Africa to Asia from

CITES permits issued to export bones escalated from ±314y-1 skeletons from 2008–2011, to ±1312y-1 skeletons from 2013–2015. South Africa was the only legal exporter of bones to Asia until 2013 when Namibia issued permits to export skeletons to Vietnam. While CITES permits to export ±5363 skeletons from Africa

2017-01-01

Aims: In the Far East, there has generally been low uptake of oral anticoagulants (OACs) using vitamin K antagonists (VKA, e.g. warfarin) for stroke prevention in atrial fibrillation (AF), but OAC use has been increasing more recently, with the introduction of the non-vitamin K antagonist oral...... anticoagulants (NOACs). To explore the risks of ischaemic stroke (IS) and death related to AF in East Asia using modelling projections. Methods and results: We performed a modelling analysis of possible trends of IS and death rates in AF patients from the time period of only VKA use to current increasing trends....... There was an estimated annual risk reduction of 5484 ISs and 1128 deaths from 2016 to 2030, respectively. The AF population is estimated to reach 861 900 in 2050, with a reduction of 206 315 ISs and 139 353 deaths. Conclusion: This modelling analysis suggests that the transition from VKA to NOACs may greatly help...

The very long baseline interferometry (VLBI) technique offers angular resolutions superior to any other instruments at other wavelengths, enabling unique science applications of high-resolution imaging of radio sources and high-precision astrometry. The East Asia VLBI Network (EAVN) is a collaborative effort in the East Asian region. The EAVN currently consists of 21 telescopes with diverse equipment configurations and frequency setups, allowing flexible subarrays for specific science projects. The EAVN provides the highest resolution of 0.5 mas at 22 GHz, allowing the fine imaging of jets in active galactic nuclei, high-accuracy astrometry of masers and pulsars, and precise spacecraft positioning. The soon-to-be-operational Five-hundred-meter Aperture Spherical radio Telescope (FAST) will open a new era for the EAVN. This state-of-the-art VLBI array also provides easy access to and crucial training for the burgeoning Asian astronomical community. This Perspective summarizes the status, capabilities and prospects of the EAVN.

The Middle East and the Development of a Natural Gas World Market

International Nuclear Information System (INIS)

Honore, Anouk

2006-01-01

Gas resources can easily meet the projected increase in global demand. However, international trade in energy will need to expand to accommodate the growing mismatch between the location of demand or production. The Middle East nations emerge among the leading countries, with a reserve to production ratios exceeding 100 years. Although some have significant domestic consumption, this mostly leaves ample potential for exports. Most of the incremental output in the Middle East will be exported to North America, Europe and Asia, where indigenous production will fall behind demand on the short to medium term. The key question is whether the Middle East can live up to the consuming countries' supply expectations

Impact of meteorological anomalies in the 2003 summer on Gross Primary Productivity in East Asia

Directory of Open Access Journals (Sweden)

2010-02-01

Full Text Available Northern Eurasia experienced anomalous weather conditions in the 2003 summer. We examined how forest ecosystems responded to the meteorological anomalies during the period using the dataset collected at flux monitoring sites in Asia, including a boreal forest in Mongolia, temperate forests in China and Japan, and a sub-tropical forest in China, as well as the dataset from satellite remote sensing. From July to August 2003, an active rain band stayed in the mid-latitude in East Asia for an unusually long period. Under the influence of the rain band, the Gross Primary Production (GPP, of temperate forests was 20–30% lower in the 2003 summer than in other years due to significant reduction in the Photosynthetic Photon Flux Density (PPFD. The GPP of a cool-temperate forest in the north of the rain band was slightly enhanced by the higher PPFD; however, the GPP of a sub-tropical forest located in the south of the rain band was reduced by drought stress due to extremely hot and dry conditions. The correlation coefficients for the year-to-year changes in the PPFD and GPP during mid-summer were calculated, and the spatial distribution was examined. The spatial pattern of the PPFD was calculated by satellite data, and that of the GPP was estimated by a regression-type model, which was trained and tested by ground observation data. The correlation was positive in the mid- and high-latitudes since light was an essential factor of the summer GPP. On the other hand, a negative correlation appeared in the lower latitudes, suggesting that the water limitation was much more important than the PPFD in the region. Our study illustrated that the integration of flux data from wide areas by combining satellite remote sensing data can help us gain an understanding of the ecosystem responses to large-scale meteorological phenomena.

Atmospheric concentration of 210Pb in East Asia and its contribution to Japanese islands by long-range transport

International Nuclear Information System (INIS)

Doi, Taeko; Sato, Shin; Sato, Jun

2007-01-01

Atmospheric 210 Pb is a long-lived progeny of 222 Rn generated from the earth's crust and exists as adsorbed onto the surface of aerosol particles. The distribution of atmospheric 210 Pb in East Asia reflects (1) the concentration levels in continental and maritime air masses and (2) the spatial extent of the continental air mass. This paper reviews the previously observed results on seasonal variation of 210 Pb concentration at several sites of Japan, Korea and China to evaluate the contribution of continental to Japanese atmosphere, and the specific activity of 210 Pb in the main components of aerosol samples and discusses from the view point of the Japanese islands. The authors conclude that aerosols from continental East Asia in winter contain more soil particles with low specific radioactivity of 210 Pb than the aerosols in Japan and that the natural radionuclide is extremely useful tracer for researches on meteorological phenomena and global transfer of environmental pollution.

Influences of introduced plague on North American mammals: Implications from ecology of plague in Asia

Science.gov (United States)

Biggins, D.E.; Kosoy, M.Y.

2001-01-01

Intercontinental movements of invasive species continue to modify the world's ecosystems. The plague bacterium (Yersinia pestis) has colonized and altered animal communities worldwide but has received much more attention as a human pathogen. We reviewed studies on the ecology of Y. pestis in ancient foci of central Asia and in western North America, where the bacterium apparently has become established much more recently. Although rodent populations on both continents are affected dramatically by epizootics of plague, the epidemiologically important species of Asia demonstrate resistance in portions of their populations, whereas those of North America are highly susceptible. Individual variation in resistance, which is widespread in Asian rodents and allows a microevolutionary response, has been documented in few North American species of rodents. Plague increases costs of sociality and coloniality in susceptible hosts, increases benefits of disease resistance in general, and increases benefits of adaptability to variable environments for species at higher trophic levels. Prairie dogs (Cynomys) epitomize taxa with high risk to plague because prairie dogs have uniformly low resistance to plague and are highly social. Relationships to plague are poorly understood for many North American rodents, but more than one-half of the species of conservation concern occur within the geographic range of plague.

Few studies on size-specific health effects of particulate matter have been conducted in Asia. We examined the association between both fine and coarse particles (PM_2_._5 and PM_1_0_−_2_._5) and mortality across 11 East Asian cities from 4 countries (Korea, Japan, Taiwan, and China). We performed a two-stage analysis: we generated city-specific estimates using a time-series analysis with a generalized additive model (Quasi-Poisson distribution), and estimated the overall effects by conducting a meta-analysis. Each 10−μg/m"3 increase in PM_2_._5 (lag01) was associated with an increase of 0.38% (95% confidence interval = 0.21%–0.55%) in all causes mortality, 0.96% (0.46%–1.46%) in cardiovascular mortality, and 1% (0.23%–1.78%) in respiratory mortality. Each 10−μg/m"3 increase in PM_1_0_−_2_._5 (lag01) was associated with cardiovascular mortality (0.69%, [0.05%–1.33%]), although this association attenuated after controlling for other pollutants, especially PM_2_._5. Increased mortality was associated with increasing PM_2_._5 and PM_1_0_−_2_._5 concentrations over 11 East Asian cities. - Highlights: • Few studies on size-specific health effects of PM have been conducted in East Asia. • We estimated size-specific PM effects on mortality over 11 East Asian cities. • Both fine and coarse particles were associated with mortality in East Asian cites. • Effect estimates for fine particles were higher than those for coarse particles. - Short-term exposure to PM_2_._5 and PM_1_0_−_2_._5 was associated with an increased risk of mortality in East Asian cities, and PM_2_._5 effect estimates were higher than PM_1_0_−_2_._5.

Projections of East Asian summer monsoon change at global warming of 1.5 and 2 °C

Science.gov (United States)

Liu, Jiawei; Xu, Haiming; Deng, Jiechun

2018-04-01

Much research is needed regarding the two long-term warming targets of the 2015 Paris Agreement, i.e., 1.5 and 2 °C above pre-industrial levels, especially from a regional perspective. The East Asian summer monsoon (EASM) intensity change and associated precipitation change under both warming targets are explored in this study. The multimodel ensemble mean projections by 19 CMIP5 models show small increases in EASM intensity and general increases in summer precipitation at 1.5 and 2 °C warming, but with large multimodel standard deviations. Thus, a novel multimodel ensemble pattern regression (EPR) method is applied to give more reliable projections based on the concept of emergent constraints, which is effective at tightening the range of multimodel diversity and harmonize the changes of different variables over the EASM region. Future changes projected by using the EPR method suggest decreased precipitation over the Meiyu belt and increased precipitation over the high latitudes of East Asia and Central China, together with a considerable weakening of EASM intensity. Furthermore, reduced precipitation appears over 30-40° N of East Asia in June and over the Meiyu belt in July, with enhanced precipitation at their north and south sides. These changes in early summer are attributed to a southeastward retreat of the western North Pacific subtropical high (WNPSH) and a southward shift of the East Asian subtropical jet (EASJ), which weaken the moisture transport via southerly wind at low levels and alter vertical motions over the EASM region. In August, precipitation would increase over the high latitudes of East Asia with more moisture from the wetter area over the ocean in the east and decrease over Japan with westward extension of WNPSH. These monthly precipitation changes would finally contribute to a tripolar pattern of EASM precipitation change at 1.5 and 2 °C warming. Corrected EASM intensity exhibits a slight difference between 1.5 and 2 °C, but a

Paleoclimate records of effective moisture (precipitation minus evaporation, or P-E) show a dry (low effective moisture) period in mid-latitude arid/semi-arid central Asia during the early Holocene (11,000-8,000 years ago) relative to the middle and late Holocene, in contrast to evidence for greater-than-present precipitation at the same time in the south and east Asian monsoonal areas. To investigate the spatial differences in climate response over mid-latitude central Asia and monsoonal Asia we conducted a series of simulations with the Community Climate System Model version 3 coupled climate model for the early, middle and late Holocene. The simulations test the climatic impact of all important forcings for the early Holocene, including changes in orbital parameters, the presence of the remnant Laurentide ice sheet and deglacial freshening of the North Atlantic. Model results clearly show the early Holocene patterns indicated by proxy records, including both the decreased effective moisture in arid central Asia, which occurs in the model primarily during the winter months, and the increase in summer monsoon precipitation in south and east Asia. The model results suggest that dry conditions in the early Holocene in central Asia are closely related to decreased water vapor advection due to reduced westerly wind speed and less evaporation upstream from the Mediterranean, Black, and Caspian Seas in boreal winter. As an extra forcing to the early Holocene climate system, the Laurentide ice sheet and meltwater fluxes have a substantial cooling effect over high latitudes, especially just over and downstream of the ice sheets, but contribute only to a small degree to the early Holocene aridity in central Asia. Instead, most of the effective moisture signal can be explained by orbital forcing decreasing the early Holocene latitudinal temperature gradient and wintertime surface temperature. We find little evidence for regional subsidence related to a stronger summer Asian

The Asian cultivated rice, Oryza sativa, is one of the most important crops feeding more than a third of global population. In spite of the studies for several decades, the origin and domestication history of rice varietal groups, japonica and indica, have not been fully unveiled. Genetic information of ancient rice remains is essential for direct and exclusive insight into the domestication history of rice. We performed ancient DNA analysis of 950- to 2,800-year-old rice remains excavated from Japan and Korea. We found the presence of both japonica- and indica-type varieties in the Yayoi period and the middle ages of Japan and the middle part of Korea Peninsula 2,000 years ago. It is popularly considered that japonica has been exclusively cultivated in northern part of East Asia including Japan and Korea. Our result disclosed unexpectedly wide diversity of rice varieties in archaic East Asia. The present results from ancient rice DNA reveal an exclusive insight for the domestication history of rice which is not provided as far as contemporary rice. © The Author 2016.

Potential cooperative measures on nuclear issues in Asia

International Nuclear Information System (INIS)

Olsen, J.

1997-01-01

Cooperation on nuclear issues is receiving increased attention in Asia. In Northeast Asia, where the nuclear industry is well-developed, cooperation in the back end of the nuclear fuel cycle could help deal with issues such as disposition of spent fuel and long term storage options. In Southeast Asia, where countries are just beginning to introduce nuclear energy, cooperation would be useful in developing standards for the nuclear industry. Throughout Asia, nuclear research and power activities can raise concerns about safety, environmental pollution and proliferation. The sharing of relevant information, i.e. cooperative monitoring, will be essential to addressing these issues. In fact, a number of regional interactions on nuclear issues are already occurring. These range from training exchanges sponsored by the more advanced states to participation in environmental monitoring of the East Sea (Sea of Japan). Several states are considering sharing information from their nuclear facilities; some exchanges of radiation data are already in place. The KEDO reactor project will involve close working relations between the nuclear experts of South Korea, North Korea, Japan, and the US. Areas for further regional cooperation are discussed

Regional precipitation variability in East Asia related to climate and environmental factors during 1979-2012

2014-01-01

This paper studies the inter-annual precipitation variations in different regions of East Asia from oceans to interior areas in China during 1979 – 2012. The results computed by Empirical Orthogonal Functions (EOF) demonstrate that the annual precipitation changes are mainly related to the El Niño-Southern Oscillation, East Asian summer monsoon and aerosols. We also found that the increased Sea surface temperature (SST) could explain the precipitation changes over the Northwest Pacific in the dry season (Oct. – May) and the East China Sea and the South China Sea in the rainy season (Jun. – Sep.). The precipitation changes over the ocean unexplained by SST were likely due to the water vapor transport dominated by dynamic factors. With the increased SST, the moisture transported from oceans to interior land was likely redistributed and caused the complicated regional variability of precipitation. Moreover, the impacts of aerosols on cloud and precipitation varied with different pollution levels and different seasons. PMID:25033387

2018-03-01

The influence of boreal winter-spring eastern Tibetan Plateau snow anomalies on the East Asian summer rainfall variability has been the focus of previous studies. The present study documents the impacts of boreal summer western and southern Tibetan Plateau snow cover anomalies on summer rainfall over East Asia. Analysis shows that more snow cover in the western and southern Tibetan Plateau induces anomalous cooling in the overlying atmospheric column. The induced atmospheric circulation changes are different corresponding to more snow cover in the western and southern Tibetan Plateau. The atmospheric circulation changes accompanying the western Plateau snow cover anomalies are more obvious over the midlatitude Asia, whereas those corresponding to the southern Plateau snow cover anomalies are more prominent over the tropics. As such, the western and southern Tibetan Plateau snow cover anomalies influence the East Asian summer circulation and precipitation through different pathways. Nevertheless, the East Asian summer circulation and precipitation anomalies induced by the western and southern Plateau snow cover anomalies tend to display similar distribution so that they are more pronounced when the western and southern Plateau snow cover anomalies work in coherence. Analysis indicates that the summer snow cover anomalies over the Tibetan Plateau may be related to late spring snow anomalies due to the persistence. The late spring snow anomalies are related to an obvious wave train originating from the western North Atlantic that may be partly associated with sea surface temperature anomalies in the North Atlantic Ocean.

This study estimated the health and economic burden of child maltreatment in the East Asia and Pacific region, addressing a significant gap in the current evidence base. Systematic reviews and meta-analyses were conducted to estimate the prevalence of child physical abuse, sexual abuse, emotional abuse, neglect, and witnessing parental violence. Population Attributable Fractions were calculated and Disability-Adjusted Life Years (DALYs) lost from physical and mental health outcomes and health risk behaviors attributable to child maltreatment were estimated using the most recent comparable Global Burden of Disease data. DALY losses were converted into monetary value by assuming that one DALY is equal to the sub-region's per capita GDP. The estimated economic value of DALYs lost to violence against children as a percentage of GDP ranged from 1.24% to 3.46% across sub-regions defined by the World Health Organization. The estimated economic value of DALYs (in constant 2000 US$) lost to child maltreatment in the EAP region totaled US $151 billion, accounting for 1.88% of the region's GDP. Updated to 2012 dollars, the estimated economic burden totaled US $194 billion. In sensitivity analysis, the aggregate costs as a percentage of GDP range from 1.36% to 2.52%. The economic burden of child maltreatment in the East Asia and Pacific region is substantial, indicating the importance of preventing and responding to child maltreatment in this region. More comprehensive research into the impact of multiple types of childhood adversity on a wider range of putative health outcomes is needed to guide policy and programs for child protection in the region, and globally.

East Asian winter temperature variation associated with the combined effects of AO and WP pattern

Park, Hye-Jin; Ahn, Joong-Bae

2016-04-01

The combined effects of the Arctic Oscillation (AO) and Western Pacific (WP) teleconnection pattern on the East Asian winter monsoon (EAWM) over the last 56 years (1958/59-2013/2014) were investigated using NCEP/NCAR reanalysis data (Park and Ahn, 2015). The study results revealed that the effect of the AO on winter temperature in East Asia could be changed depending on the phases of the WP pattern in the North Pacific. The negative relationship between the EAWM and the AO increased when the AO and WP were in-phase with each other. Hence, when winter negative (positive) AO was accompanied by negative (positive) WP, negative (positive) temperature anomalies were dominant across the entire East Asia region. Conversely, when the AO and WP were of-of-phase, the winter temperature anomaly in East Asia did not show distinct changes. Furthermore, from the perspective of stationary planetary waves, the zonal wavenumber-2 patterns of sea level pressure and geopotential height at 500hPa circulation strengthened when the AO and WP were in-phase but were not significant for the out-of-phase condition. It explained the possible mechanism of the combined effects of the AO and WP on the circulation related to EAWM. Reference Park, H.-J., and J.-B.

Impact of boreal summer intraseasonal oscillation on heat wave occurrence in Asia and Europe during the summer of 2016

Science.gov (United States)

Lee, June-Yi; Hsu, Pang-Chi; ha, Kyung-Ja; Kim, Hae-Jeong; Jung, Yoo-Rim

2017-04-01

The summer of 2016 was the earth's hottest summer on record since 1880. Especially, in August, the global mean temperature was 1.66 degree higher than normal and heat waves set records across Asia, Europe, and North America. This study proposes that boreal summer intraseasonal oscillation (BSISO) played an important role in heat wave outbreaks over many regions of the Northern Hemisphere (NH) extratropics in the summer 2016 in addition to other factors including global warming, atmosphere-land interaction, and Africa-Pakistan heavy rainfall. By utilizing the real-time multivariate BSISO indices recently proposed, it has been demonstrated that the two dominant BSISO modes significantly modulate occurrence probability and spatial distributions of extreme rainfall and heat wave over Asia and Europe depending on their phases. The BSISO1 represents the canonical northward propagating variability that often occurs in conjunction with the eastward propagating Madden-Julian Oscillation with quasi-oscillating periods of 30-60 days. The BSISO2 represents the northward/northwestward propagating variability with periods of 10-30 days during primarily the pre-monsoon and monsoon-onset season. In August of 2016, BSISO1 was very active with amplitude up to 2 standard deviation and stayed at phase 7 state for about 20 days. During the phase 7 of BSISO1, extreme convective activity over the South China Sea and western North Pacific typically exerts significant global teleconnection leading to heat wave occurrence over East Asia including Korea and Japan, some part of Russia and Europe, and the western and eastern part of North America. In particular, anticyclonic circulation anomaly tends to be developed over East Asia inducing enhanced adiabatic and diabatic warming over Korea and Japan providing a favorable condition for extreme heat wave occurrence. The August of 2016 exhibited the typical global teleconnection pattern of BSISO1 associated with active convection over the western

Natural and Anthropogenically Perturbed Biogenic Aerosol over Tropical South East Asia

Coe, H.; Robinson, N.; Allan, J. D.; Hewitt, C. N.

Tropical forested regions are of interest as sources of atmospheric aerosol since they cover very large areas of the tropics and are a source of a large amount of volatile organic compounds which act as precursors for particle formation. Natural forest regions offer the potential to study the background state of the tropics and so potentially gain some insight into the pre-perturbed atmosphere. However, over the last decade in South East Asia, a considerable fraction of the native tropical deciduous forest has been deforested and replanted with palm oil plantations. This changes the range of volatile organic compounds that are emitted and act as sources of secondary organic aerosol. A suite of intensive ground and airborne measurements were made over both tropical forest and oil palm plantations in Sabah, Malaysia as part of the "Oxidant and Particle Photochemical Processes above a South East Asian tropical rainforest (OP3) during 2008. These data will be used together with recent improvements in our understanding of aerosol formation from biogenic compounds to discuss aerosol formation in tropical regions and the influence of human influence through widespread palm oil agriculture.

Cities, as places where human activities are concentrated, account for a small percent of global land cover but are frequently cited as the chief causes of, and solutions to, climate, biogeochemistry, and hydrology processes at local, regional, and global scales. Accompanying with uncontrolled economic growth, urban sprawl has been attributed to the accelerating integration of East Asia into the world economy and involved dramatic changes in its urban form and land use. To understand the impact of urban extent on biogeophysical processes, reliable mapping of built-up areas is particularly essential in eastern cities as a result of their characteristics of smaller patches, more fragile, and a lower fraction of the urban landscape which does not have natural than in the West. Segmentation of urban land from other land-cover types using remote sensing imagery can be done by standard classification processes as well as a logic rule calculation based on spectral indices and their derivations. Efforts to establish such a logic rule with no threshold for automatically mapping are highly worthwhile. Existing automatic methods are reviewed, and then a proposed approach is introduced including the calculation of the new index and the improved logic rule. Following this, existing automatic methods as well as the proposed approach are compared in a common context. Afterwards, the proposed approach is tested separately in cities of large, medium, and small scale in East Asia selected from different LANDSAT images. The results are promising as the approach can efficiently segment urban areas, even in the presence of more complex eastern cities.

Based on the bi-linearly interpolated meteorological reanalysis data from National Centers for Environmental Prediction, USA and by using the leaf area index data derived from the GIMMS NDVI to run the process-based Boreal Ecosystems Productivity Simulator (BEPS) model, this paper simulated and analyzed the spatiotemporal characteristics of the terrestrial ecosystem gross primary productivity (GPP) and net primary productivity (NPP) in East Asia in 2000-2005. Before regional simulating and calculating, the observation GPP data of different terrestrial ecosystem in 15 experimental stations of AsiaFlux network and the inventory measurements of NPP at 1300 sampling sites were applied to validate the BEPS GPP and NPP. The results showed that BEPS could well simulate the changes in GPP and NPP of different terrestrial ecosystems, with the R2 ranging from 0.86 to 0.99 and the root mean square error (RMSE) from 0.2 to 1.2 g C x m(-2) x d(-1). The simulated values by BEPS could explain 78% of the changes in annual NPP, and the RMSE was 118 g C x m(-2) x a(-1). In 2000-2005, the averaged total GPP and total NPP of the terrestrial ecosystems in East Asia were 21.7 and 10.5 Pg C x a(-1), respectively, and the GPP and NPP exhibited similar spatial and temporal variation patterns. During the six years, the total NPP of the terrestrial ecosystems varied from 10.2 to 10.7 Pg C x a(-1), with a coefficient of variation being 2. 2%. High NPP (above 1000 g C x m(-2) x a(-1)) occurred in the southeast island countries, while low NPP (below 30 g C x m(-2) x a(-1)) occurred in the desert area of Northwest China. The spatial patterns of NPP were mainly attributed to the differences in the climatic variables across East Asia. The NPP per capita also varied greatly among different countries, which was the highest (70217 kg C x a(-1)) in Mongolia, far higher than that (1921 kg C x a(-1)) in China, and the lowest (757 kg C x a(-1)) in India.

Rice bean [Vigna umbellate (Thumb.) Ohwi and Ohashi] is an underutilized crop believed to be domesticated in the Myanmar-Thailand region of Asia. In India, rice bean is mainly cultivated in the North-Eastern Hills, which is a hotspot for biological diversity. A 5' anchored PCR was used to develop microsatellite markers in rice bean. Twenty-eight specific primer pairs were designed and employed to characterize sixty five ricebean accessions collected from North East India. A total of 179 alleles were amplified with an average of 6.393 alleles per locus. The gene diversity was high (mean 0.534) in the accessions collected from Darjeeling, Nagaland and Manipur, which are bordering areas with East Nepal and Myanmar, respectively. Exceptionally high outcrossing rate was observed in the entire population. Population structure analysis identified three distinct clusters in which accessions collected from areas bordering Myanmar and East Nepal grouped separately. Using a combination of STRUCTURE and Principal Coordinate Analysis, relative affinity of the intermediate accessions could be established. However, differences in allelic counts among populations were non-significant. The results showed that there is a high level of genetic diversity within the accessions, with high outcrossing rate.

The Asia Pacific natural gas market: Large enough for all?

2014-01-01

Among natural gas producing nations, there has been some concern about how the Asia Pacific will meet future demand for energy. We argue that natural gas, both regional and global, will play a vital role. Estimates of potential gas consumption in the region are analyzed and used to develop consensus projections to 2030. These consumption profiles are compared with gas supply estimates including indigenous, pipeline and LNG for the Asia Pacific market. From this analytical framework, we find that demand will be sufficiently large to accommodate supplies from diverse sources including North America, the Middle East, Central Asia, Russia, and the Asia Pacific itself. An important policy implication is that gas producing and consuming nations should benefit from promoting gas trade and not be concerned about a situation of potential lack of demand coupled with oversupply. - Highlights: • Estimates of gas consumption in the Asia Pacific (AP) in 2030 are presented. • Compared with supply estimates for AP including indigenous, pipeline, and LNG. • Find that demand in AP large enough to accommodate supply from all regions. • Nations should promote gas trade policy and not be overly concerned about oversupply

The biogeographical relationships between far-separated populations, in particular, those in the mainland and islands, remain unclear for widespread species in eastern Asia where the current distribution of plants was greatly influenced by the Quaternary climate. Deciduous Oriental oak (Quercus variabilis) is one of the most widely distributed species in eastern Asia. In this study, leaf material of 528 Q. variabilis trees from 50 populations across the whole distribution (Mainland China, Korea Peninsular as well as Japan, Zhoushan and Taiwan Islands) was collected, and three cpDNA intergenic spacer fragments were sequenced using universal primers. A total of 26 haplotypes were detected, and it showed a weak phylogeographical structure in eastern Asia populations at species level, however, in the central-eastern region of Mainland China, the populations had more haplotypes than those in other regions, with a significant phylogeographical structure (N ST = 0.751> G ST = 0.690, Ptree showed a rapid speciation during Pleistocene, with a population augment occurred in Middle Pleistocene. Both diversity patterns and ecological niche modelling indicated there could be multiple glacial refugia and possible bottleneck or founder effects occurred in the southern Japan. We dated major spatial expansion of Q. variabilis population in eastern Asia to the last glacial cycle(s), a period with sea-level fluctuations and land bridges in East China Sea as possible dispersal corridors. This study showed that geographical heterogeneity combined with climate and sea-level changes have shaped the genetic structure of this wide-ranging tree species in East Asia. PMID:23115642

Understanding the past significant changes of the East Asia Summer Monsoon (EASM) and Winter Monsoon (EAWM) is critical for improving the projections of future climate over East Asia. One key issue that has remained outstanding from the paleo-climatic records is whether the evolution of the EASM and EAWM are correlated. Here, using a set of long-term transient simulations of the climate evolution of the last 21,000 years, we show that the EASM and EAWM are positively correlated on the orbital timescale in response to the precessional forcing, but are anti-correlated on millennial timescales in response to North Atlantic melt water forcing. The relation between EASM and EAWM can differ dramatically for different timescales because of the different response mechanisms, highlighting the complex dynamics of the East Asian monsoon system and the challenges for future projection.

Full Text Available Objectives There are large populations of indigenous horse (Equus caballus in China and some other parts of East Asia. However, their matrilineal genetic diversity and origin remained poorly understood. Using a combination of mitochondrial DNA (mtDNA and hypervariable region (HVR-1 sequences, we aim to investigate the origin of matrilineal inheritance in these domestic horses. Methods To investigate patterns of matrilineal inheritance in domestic horses, we conducted a phylogenetic study using 31 de novo mtDNA genomes together with 317 others from the GenBank. In terms of the updated phylogeny, a total of 5,180 horse mitochondrial HVR-1 sequences were analyzed. Results Eightteen haplogroups (Aw-Rw were uncovered from the analysis of the whole mitochondrial genomes. Most of which have a divergence time before the earliest domestication of wild horses (about 5,800 years ago and during the Upper Paleolithic (35–10 KYA. The distribution of some haplogroups shows geographic patterns. The Lw haplogroup contained a significantly higher proportion of European horses than the horses from other regions, while haplogroups Jw, Rw, and some maternal lineages of Cw, have a higher frequency in the horses from East Asia. The 5,180 sequences of horse mitochondrial HVR-1 form nine major haplogroups (A-I. We revealed a corresponding relationship between the haplotypes of HVR-1 and those of whole mitochondrial DNA sequences. The data of the HVR-1 sequences also suggests that Jw, Rw, and some haplotypes of Cw may have originated in East Asia while Lw probably formed in Europe. Conclusions Our study supports the hypothesis of the multiple origins of the maternal lineage of domestic horses and some maternal lineages of domestic horses may have originated from East Asia.

The intercontinental biogeography between eastern Asia and eastern North America has attracted much attention from evolutionary biologists. Further insights into understanding the evolution of the intercontinental disjunctions have been hampered by the lack of studies on the intracontinental biogeography in eastern Asia, a region with complex geology, geography, climates and habitats. Herein we studied the biogeographic history of the eastern Asian-eastern North American disjunct genus Panax with special emphasis on the investigation of its uneven diversification in Asia. This study reconstructs the diversification history of Panax and also emphasizes a large clade of Panax taxa, which has a wide distribution in eastern Asia, but was unresolved in previous studies. We examined the noncoding plastid DNA fragments of trnH-psbA, rps16, and psbM-trnD, the mitochondrial b/c intron of NAD1, and the nuclear ribosomal internal transcribed spacer (ITS) region of 356 samples from 47 populations. The results revealed the subtropical Northern Hemisphere origin (Asia or Asia and North America) of Panax in the Paleocene. Intercontinental disjunctions between eastern Asia and eastern North America formed twice in Panax, once estimated in early Eocene for the split of P. trifolius and another in mid-Miocene for the divergence of P. quinquefolius. Intercontinental diversifications in Panax showed temporal correlation with the increase of global temperature. The evolutionary radiation of the P. bipinnatifidus species complex occurred around the boundary of Oligocene and Miocene. Strong genetic structure among populations of the species complex was detected and the populations may be isolated by distance. The backbone network and the Bayesian clustering analysis revealed a major evolutionary radiation centered in the Hengduan Mountains of western China. Our results suggested that the evolutionary radiation of Panax was promoted by geographic barriers, including mountain ranges

This study investigates the multidecadal variations of the interannual relationship between the East Asian summer monsoon (EASM) and El Niño-Southern Oscillation (ENSO) in 1000-year simulation of a coupled climate model. The interannual relationship between ENSO and EASM has experienced pronounced changes throughout the 1000-year simulation. During the periods with significant ENSO-EASM relationship, the ENSO-related circulation anomalies show a Pacific-Japan (PJ)-like pattern with significant wave-activity flux propagating from the tropics to the north in lower troposphere and from the mid-latitudes to the south in upper troposphere. The resultant ENSO-related precipitation anomalies are more (less) than normal over the East Asia (western North Pacific) in the decaying summers of El Niño events. In contrast, the circulation and precipitation anomalies are weak over East Asia-western North Pacific during the periods with weak ENSO-EASM relationship. Based on the energy conversion analysis, the related anomalies achieve barotropic and baroclinic energy from the mean flow during the periods with strong ENSO-EASM relationship. On the contrary, during the low-correlation periods, the energy conversion is too weak to form the link between the tropics and mid-latitudes. The main reason for the multidecadal variations of ENSO-EASM relationship is the amplitude discrepancy of SST anomalies over the Indo-western Pacific Ocean which, in turn, leads to the intensity difference of the western North Pacific anomalous anticyclone (WPAC) and related climate anomalies.

2005-05-01

Full Text Available Soil conservation in the highlands of South-East Asia is essential for sustainable agro-environmental development. The effectiveness of soil conservation treatments developed in runoff plots was investigated in farmer-managed plots on a natural catchment. This wasachieved by the development and scientific evaluation of modified and novel cropping practices in a representative highland catchment in Yunnan Province, China. Wang Jia Catchment covers 40.1 hectares near Kedu, in Xundian County, north-east Yunnan (25o28'N, 102o53'E. The initial project consisted of an evaluation of the effects of modified cropping practices on maize productivity and soil properties. This programme was extended to investigate ways of increasing the productivity of maize, wheat and soybean on fragile slopes in a sustainable and environmentally-friendly way. The approach incorporates modified and novel agronomic and soil conservation measures, with the evaluation of their agricultural, environmental and socio-economic impacts using multidisciplinary approaches. This European Union funded project involved an international research team from Belgium, China, Ireland, Thailand and the U.K. Five co-ordinated work packages were implemented.

Projections of East Asian summer monsoon change at global warming of 1.5 and 2 °C

Directory of Open Access Journals (Sweden)

J. Liu

2018-04-01

Full Text Available Much research is needed regarding the two long-term warming targets of the 2015 Paris Agreement, i.e., 1.5 and 2 °C above pre-industrial levels, especially from a regional perspective. The East Asian summer monsoon (EASM intensity change and associated precipitation change under both warming targets are explored in this study. The multimodel ensemble mean projections by 19 CMIP5 models show small increases in EASM intensity and general increases in summer precipitation at 1.5 and 2 °C warming, but with large multimodel standard deviations. Thus, a novel multimodel ensemble pattern regression (EPR method is applied to give more reliable projections based on the concept of emergent constraints, which is effective at tightening the range of multimodel diversity and harmonize the changes of different variables over the EASM region. Future changes projected by using the EPR method suggest decreased precipitation over the Meiyu belt and increased precipitation over the high latitudes of East Asia and Central China, together with a considerable weakening of EASM intensity. Furthermore, reduced precipitation appears over 30–40° N of East Asia in June and over the Meiyu belt in July, with enhanced precipitation at their north and south sides. These changes in early summer are attributed to a southeastward retreat of the western North Pacific subtropical high (WNPSH and a southward shift of the East Asian subtropical jet (EASJ, which weaken the moisture transport via southerly wind at low levels and alter vertical motions over the EASM region. In August, precipitation would increase over the high latitudes of East Asia with more moisture from the wetter area over the ocean in the east and decrease over Japan with westward extension of WNPSH. These monthly precipitation changes would finally contribute to a tripolar pattern of EASM precipitation change at 1.5 and 2 °C warming. Corrected EASM intensity exhibits a slight difference

Decadal trends in tropospheric ozone over East Asian Pacific rim during 1998-2007: Implications for emerging Asian emissions impacts and comparison to European and North American records (Invited)

Tanimoto, H.; Ohara, T.; Uno, I.

2010-12-01

We examine springtime ozone trends at nine remote locations in East Asian Pacific rim during the last decade (1998-2007). The observed decadal ozone trends are relatively small at surface sites but are substantially larger at a mountainous site. The level and increasing rate of ozone at the mountainous site are both higher than those observed at background sites in Europe and North America. We use a regional chemistry-transport model to explore the observed changes and how changes in Asian anthropogenic emissions have contributed to the observed increasing trends. The model with yearly-dependent regional emissions successfully reproduces the levels, variability, and interannual variations of ozone at all the surface sites. It predicts increasing trends at the mountainous site, suggesting that increasing Asian anthropogenic emissions account for about half the observed increase. However, the discrepancy between the observation and model results after 2003 (the time of largest emission increase) suggests significant underestimation of the actual growth of the Asian anthropogenic emissions and/or incompleteness in the modeling of pollution export from continental Asia. These findings imply that improving emissions inventory and transport scheme is needed to better understand rapidly evolving tropospheric ozone in East Asia and its potential climatic and environmental impacts.

2008-02-01

Full Text Available The spatial-temporal distributions and sources of sand and dust storm (SDS in East Asia from 2001 to 2006 were investigated on the basis of visibility and PM₁₀ data from the routine SDS and weather monitoring networks run by CMA (China Meteorological Administration. A power functional relationships between PM₁₀ and visibility was found among various regions generally with a good correlation (r²=0.90, especially in Asian SDS source regions. In addition, three SDS occurrence centers, i.e. western China, Mongolia and northern China, were identified with the Mongolia source contributing more dust to the downwind areas including Korea and Japan than other two sources. Generally, high PM₁₀ concentrations were observed in most areas of northern China. The highest value was obtained in the center of western China with a spring daily mean value of 876 μgm⁻³, and the value in other source regions exceeds 200 μgm⁻³. These data sets together with the satellite observations in China form the main observation database for the evaluation and data assimilation of CUACE/Dust system – an operational SDS forecasting system for East Asia.

Many peninsulas in the temperate zone played an important role as refugia of various flora and fauna, and the southern Korean Peninsula also served as a refugium for many small mammals in East Asia during the Pleistocene. The Asian lesser white-toothed shrew, Crocidura shantungensis, is a widely distributed species in East Asia, and is an appropriate model organism for exploring the role of the Korean Peninsula as a refugium of small mammals. Here, we investigated phylogenetic relationships and genetic diversity based on the entire sequence of the mitochondrial cytochrome b gene (1140 bp). A Bayesian tree for 98 haplotypes detected in 228 C. shantungensis specimens from East Asia revealed the presence of three major groups with at least 5 subgroups. Most haplotypes were distributed according to their geographic proximity. Pairwise F ST 's and analysis of molecular variance (AMOVA) revealed a high degree of genetic differentiation and variance among regions as well as among populations within region, implying little gene flow among local populations. Genetic evidence from South Korean islands, Jeju-do Island of South Korea, and Taiwan leads us to reject the hypothesis of recent population expansion. We observed unique island-type genetic characteristics consistent with geographic isolation and resultant genetic drift. Phylogeographic inference, together with estimates of genetic differentiation and diversity, suggest that the southern most part the Korean Peninsula, including offshore islands, played an important role as a refugium for C. shantungensis during the Pleistocene. However, the presence of several refugia on the mainland of northeast Asia is also proposed.

Does Sustainability Affect Corporate Performance and Economic Development? Evidence from the Asia-Pacific region and North America

Directory of Open Access Journals (Sweden)

Kyungbok Kim

2018-03-01

Full Text Available This paper explores how sustainability influences financial returns and economic development in the Asia-Pacific region and North America, utilizing real data empirically. It is controversial that sustainable activities are related to financial performance. For clarification, we tested hypotheses analyzing sustainability index, seven stock markets, financial data such as ROI, ROIC, and ROA from eleven companies, and GDP/GNI per capita, based on the Asia-Pacific region and North America. The results indicate that both financial return for companies and economic development in the two regions are positively germane to sustainable investment. Besides, we found evidence that sustainable investment impacts economic development based on variance decomposition analysis, depending on GDP per capita between the two regions. This implication will be interesting for both practitioners and researchers regarding the measurement of sustainable performance.

Growing threat of intense tropical cyclones to East Asia over the period 1977–2010

International Nuclear Information System (INIS)

Park, Doo-Sun R; Ho, Chang-Hoi; Kim, Joo-Hong

2014-01-01

The threat of intense tropical cyclones (TCs) to East Asia has increased in recent decades. Integrated analyses of five available TC data sets for the period 1977–2010 revealed that the growing threat of TCs primarily results from the significant shift that the spatial positions of the maximum intensity of TCs moved closer to East Asian coastlines from Vietnam to Japan. This shift incurs a robust increase in landfall intensity over east China, Korea and Japan. In contrast, an increase of TC genesis frequency over the northern part of the South China Sea leads to a reduction in the maximum TC intensity before landfall, because of their short lifetime; thus, there are no clear tendencies in the landfall intensity across Vietnam, south China and Taiwan. All changes are related to the strengthening of the Pacific Walker circulation, closely linked with the recent manifestation that the warming trend of sea surface temperature in the tropical western Pacific is much higher than that in the central to eastern Pacific.

In 2013, ESCAP's members adopted the Bangkok Declaration to enhance efforts towards deeper regional economic integration. Yet this document neither proposes a concrete modality or modalities of achieving deeper integration, nor provides a sense of distance of individual countries to a "perceived" integrated Asia-Pacific.This paper aims to comprehensively quantify recent integration efforts of economies in the Asia-Pacific region. We provide an "index of integration effort" based on twelve metrics that measure the relative distance of a given economy to the region as an economic entity. Generally, we find that while the region has trended towards becoming integrated in general, both the level of integration and integration effort are inconsistent among Asia-Pacific economies. We discuss potential applications and extensions of the index in developing our perspective of the region's economic and social dynamics.

The present paper examined the teleconnections between two huge Asian summer monsoon components (South and East Asia) during three time slices in future: near-(2010-2039), mid-(2040-2069) and far-(2070-2100) futures under the RCP4.5 and RCP8.5 scenarios. For this purpose, a high-resolution atmospheric general circulation model is used and integrated at 40 km horizontal resolution. To get more insight into the relationships between the two Asian monsoon components, we have studied the spatial displaying correlation coefficients (CCs) pattern of precipitation over the entire Asian monsoon region with that of South Asia and three regions of East Asia (North China, Korea-Japan and Southern China) separately during the same three time slices. The possible factors responsible for these teleconnections are explored by using mean sea level pressure (MSLP) and wind fields at 850 hPa. The CC pattern of precipitation over South Asia shows an in-phase relationship with North China and an out-of-phase relationship with Korea-Japan, while precipitation variations over Korea-Japan and Southern China exhibit an out-of-phase relationship with South Asia. The CCs analysis between the two Asian blocks during different time slices shows the strongest CCs during the near and far future with the RCP8.5 scenario. The CC pattern of precipitation over Korea-Japan and Southern China with the wind (at 850 hPa) and MSLP fields indicate that the major parts of the moisture over Korea-Japan gets transported from the west Pacific along the western limb of NPSH, while the moisture over Southern China comes from the Bay of Bengal and South China Seas for good monsoon activity.

Pitmatic: the talk of the north east coalfields

The dictionary of Pitmatic, the oddly-named argot of north-east Englands miners for more than 150 years, has been compiled through detailed research in archives and interviews with the last generation to talk of kips, corf-batters and arse-loops. First recorded in Victorian newspapers, the language was part of the intense camaraderie of underground working which excluded even friendly outsiders such as the parliamentary commissioners pressing for better conditions in the pits in 1842. 'The barriers to our intercourse were formidable,' they wrote in their report on encountering the Pitmatic dialect. 'Numerous mining technicalities, northern provincialisms, peculiar intonation and accents and rapid and indistinct utterance rendered it essential for us to devote time to the study of these peculiarities ere we could translate and write the evidence.' The book includes pit recollections and analysis of the origins of the dialect's words. It reveals a rich combination of borrowings from Old Norse, Dutch and a score of other languages, with inventive usages dreamed up by the miners themselves. Part-financed by the Heritage Lottery Fund, in a three-stage dialect study of the north-east called Wor Language, the dictionary reveals the deeply practical nature of Pitmatic. The dialect was originally called Pitmatical, and its curious name was a parallel to mathematics, intended to stress the skill, precision and craft of the colliers' work.

In the present study the links between spring Arctic Oscillation (AO) and East Asian summer monsoon (EASM) was investigated with focus on the importance of the North Pacific atmospheric circulation and sea surface temperature (SST). To reduce the statistical uncertainty, we analyzed high-pass filtered data with the inter-annual time scales, and excluded the El Nino/Southern Oscillation signals in the climate fields using a linear fitting method. The significant relationship between spring AO and EASM are supported by the changes of multi-monsoon components, including monsoon indices, precipitation, and three-dimensional atmospheric circulations. Following a stronger positive spring AO, an anomalous cyclonic circulation at 850 hPa appears in southeastern Asia and the western North Pacific in summer, with the easterly anomalies spanning from the Pacific to Asian continent along 25 N-30 N and the westerly anomalies south of 15 N. At the same time, the summer western North Pacific subtropical high becomes weaker. Consistently, the positive precipitation anomalies are developed over a broad region south of 30 N stretching from southern China to the western Pacific and the negative precipitation anomalies appear in the lower valley of the Yangtze River and southern Japan. The anomalous cyclone in the western North Pacific persisting from spring to summer plays a key role in modulating EASM and monsoon precipitation by a positive air-sea feedback mechanism. During spring the AO-associated atmospheric circulation change produces warmer SSTs between 150 E-180 near the equator. The anomalous sensible and latent heating, in turn, intensifies the cyclone through a Gill-type response of the atmosphere. Through this positive feedback, the tropical atmosphere and SST patterns sustain their strength from spring to summer, that consequently modifies the monsoon trough and the western North Pacific subtropical high and eventually the EASM precipitation. Moreover, the SST response to

Increasing population and urbanization have created stress on developing nations. The quickly shifting patterns of vegetation change in different parts of the world have given rise to the pertinent question of feedback on the climate prevailing on local to regional scales. It is now known with some certainty, that vegetation changes can affect the climate by influencing the heat and water balance. The hydrological cycle particularly is susceptible to changes in vegetation. The Monsoon rainfall forms a vital link in the hydrological cycle prevailing over South East Asia This work examines the variability of vegetation over South East Asia and assesses its impact on the monsoon rainfall. We explain the role of changing vegetation and show how this change has affected the heat and energy balance. We demonstrate the role of vegetation one season earlier in influencing rainfall intensity over specific areas in South East Asia and show the ramification of vegetation change on the summer rainfall behavior. The vegetation variability study specifically focuses on India and China, two of the largest and most populous nations. We have done an assessment to find out the key meteorological and human induced parameters affecting vegetation over the study area through a spatial analysis of monthly NDVI values. This study highlights the role of monsoon rainfall, regional climate dynamics and large scale human induced pollution to be the crucial factors governing the vegetation and vegetation distribution. The vegetation is seen to follow distinct spatial patterns that have been found to be crucial in its eventual impact on monsoon rainfall. We have carried out a series of sensitivity experiments using a land surface hydrologic modeling scheme. The vital energy and water balance parameters are identified and the daily climatological cycles are examined for possible change in behavior for different boundary conditions. It is found that the change from native deciduous forest
