The effects of sea surface temperature (SST) gradient induced by the previous typhoon on the following typhoon motion over East Asia have been investigated using Weather Research and Forecasting (WRF) model for the previous Typhoon Bolaven (1215) and following Typhoon Tembin (1214). It was observed that Typhoon Bolaven remarkably reduced SST by about $7^{\circ}C$ at Yellow Sea buoy (YSbuoy). Using the WRF experiments for the imposed cold wake over West of Tembin (WT) and over East of Tembin (ET), this study demonstrates that the effects of eastward SST gradient including cold wake over WT is much significant rather than that over ET in relation to unexpected Tembin's eastward deflection. This difference between two experiments is attributed to the fact that cold wake over WT increases the magnitude of SST gradient under the eastward SST gradient around East Asia and the resultant asymmetric flow deflects Typhoon Tembin eastward, which is mainly due to the different atmospheric response to the SST forcing between ET and WT. Therefore, it implies that the enhanced eastward SST gradient over East Asia results in larger typhoon deflection toward the region of warmer SST according to the location of the cold wake effect. This result can contribute to the improvement of track prediction for typhoons influencing the Korean Peninsula

Background: Worldwide, the incidence of cancers is increasing and is becoming a major public health issue, including those in the Asia Pacific region. South-East Asia is a region with diverse populations with different disease spectra. This study looked at the spectrum of cancers among South-East Asians working in Brunei Darussalam. Materials and Methods: The cancer registry from 1994 to 2012 maintained by the State Laboratory was retrospectively reviewed. Crude incidence rates were calculated based on the population census of 2010. Results: Altogether, there was a total of 418 cancer cases diagnosed among South-East Asians, giving an incidence of 5.1% (n=418/8,253). The affected nationals in decreasing frequency were Malaysians (53.1%), followed by Filipinos (25.8%), Indonesians (15.3%), Thais (3.8%), Myanmese (1.7%) and Vietnamese (0.2%) with no recorded cases for Singapore and the People's Republic of Laos. The overall mean age of diagnosis was $46.1{\pm}4.2$ years old, with an increasing trend over the years (p<0.05 ANOVA). The overall gender ratio was 42.3:57.7 (male:female), more females among the Filipinos and Indonesians, more males among the Thais, and equal representation among the Malaysians and the Myanmese. The most common were cancers of the digestive system (19.9%), followed by female reproductive/gynecologic system (16.0%), breast (15.6%), hematological/lymphatic (12.0%) and head/neck (8.1%). There were differences in the prevalence of cancers among the various nationalities with highest crude incidence rate among the Myanmese (141.2/100,000), followed by the Malaysian (88.5/100,000), and the Filipinos (40.6/100,000) and the lowest among the Thais (18.4/100,000), Indonesians (10.5/100,000) and the Vietnamese (6.3/100,000). Conclusions: Cancers among South-East Asian residing in Brunei Darussalam accounted for 5.1% of all cancers. The most common cancers were cancers of the digestive, gynecologic/female reproductive system and breast with certain types slowly increasing in proportions. There mean age of diagnoses was increasing.

This thesis examines analyzing how historic knowledge was shaped in museum. Examining by Tokyo Imperial Museum, Government General Museum of Taiwan, Yi Wang Ga Museum, Government General Museum of Chosun, and NanTong Museum of late 19th and early 20th century, tried to find out similarities and differences. These museums are similar in that they adopt museums as modern system considering models of other countries(Europe or Japan) and exhibitions played important roles in gathering relics. Experts who leaded adoption of western civilization played an important role. These experts were conservatives who valued tradition and relics while they aimed for western civilization. It originated in the character of museum system. Historical Knowledge by museums was constituted with five combinations of conceptions which are nationality, locality, coloniality, and artistry. Every museum cannot help having modernity for museum itself is modern system. Modernity was symbolized by museum building of western style in Yi Wang Ga Museum, Government General Museum of Chosun. Tokyo Imperial Museum revealed nationality in that it tried building of imperial history which includes colonies. In early time, Tokyo Imperial Museum pursued modernity and artistry, however it concentrated on artistry than modernity later. We can find locality in that Tokyo Imperial Museum tried to find meaning about Japanese art by relating with natural characteristics. It is Taiwan Governor Museum that extremely expressed coloniality and artistry was not considered. Government General Museum of Chosun could not be exceptions of features of coloniality, but it need to recognize that artistry was focused all over the exhibitions. It was NanTong Museum that most directly expressed locality. Like these, Museums of East Asia established in around 1900 made different historical knowledge by varying weigh of five factors, nationality, locality, modernity, coloniality and artistry.

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.

This study explores the main causes that have led Japan to conclude an FTA with ASEAN. This paper appraises Japan-ASEAN relations and shows that closer relations between Japan and ASEAN have provided momentum for the launch of Japan's FTAs with ASEAN. Consequently, this paper explores the origins and progress of Japan-ASEAN FTA, as well as the strategies and initiatives embraced by Japan in its FTA negotiations with ASEAN. By examining the domestic, regional, and global factors that led to the launch of the Japan-ASEAN FTA, this paper concludes that the strategies adopted were primarily aimed at its main rival, China. The rivalry has resulted in both positive and negative consequences for East Asian Regional economic environment. The negative consequences include the creation of a "spaghetti bowl", which increases costs for Japanese firms operating abroad, and "slows down the progress of the creation of an effective single regional institution".

Three Loxoconcha Sars, 1866 (L. bizenensis Okubo, 1980, L. japonica Ishizaki, 1968, and L. tosaensis Ishizaki, 1968), one Loxocorniculum Benson and Coleman, 1963 (Lc. mutsuense Ishizaki, 1971), and two Pontocythere Dubowsky, 1939 (P. miurensis(Hanai, 1959), and P. xiphoidea Nakao and Tsukagoshi, 2002) species are briefly redescribed and illustrated. Soft part morphology of L. tosaensis are described and illustrated here for the first time, since this species was known only by the shell morphology. A key to all living Loxoconcha and Loxocorniculum species from East Asia is suggested to facilitate subsequent identification, along with the lists to all East Asian species of the three genera.

Foot-and-mouth disease (FMD) is the most contagious disease of mammals. The use of inactivated vaccine can be chosen to prevent or control FMD. However, vaccination against one serotype of FMDV doses not cross-protect against other serotypes and may not protect fully against some strains of the same serotype. Appropriate selection of vaccine strain is an important element in the control of FMD. The immunity of vaccine antigens should be matched against newly circulating viruses. The phylogenetic analysis of serotype Asia1 reported from China, Mongolia, North Korea and Russia since 2005 shows that they are all classified into genetic group V, but the strain, Asia1/Shamir (ISR/89) which have been used as a vaccine strain in Korea, is clustered into different genetic group. So, in this study the serological relationship between the isolate (Asia1/MOG/05; MOG) and the Shamir strain was determined by ELISA and virus neutralization test. Even though the matching value of the virus (MOG) against the vaccinated sera in target animals was not so high, the vaccinated animals elicited antibodies enough for protection after vaccinated once or twice. Conclusively, we suggest that the vaccine containing Asia1/Shamir antigen could protect the genetic group V strains circulating in East Asia currently if vaccinated twice or the more.

East Asia, which includes China, Japan, Korea, and Mongolia, is highly impacted by hydroclimate extremes such drought, flood, and typhoon recent year. In 2017, more than 18.5 million hectares of crops have been damaged in China, and Korea has suffered economic losses as a result of severe drought. Satellite-derived rainfall products are becoming more accurate as space and time resolution become increasingly higher, and provide an alternative means of estimating ground-based rainfall. In this study, we verified the availability of rainfall products by comparing widely used satellite images such as Climate Hazards Groups InfraRed Precipitation with Station (CHIRPS), Global Precipitation Climatology Centre (GPCC), and Precipitation Estimation From Remotely Sensed Information Using Artificial Neural Networks-Climate Data Record (PERSIANN-CDR) with ground stations in East Asia. Also, the satellite-based rainfall products were used to calculate the Standardized Precipitation Index (SPI). The temporal resolution is based on monthly images and compared with the past 30 years data from 1989 to 2018. The comparison between rainfall data based on each satellite image products and the data from weather station-based weather data was shown by the coefficient of determination and showed more than 0.9. Each satellite-based rainfall data was used for each grid and applied to East Asia and South Korea. As a result of SPI analysis, the RMSE values of CHIRPS were 0.57, 0.53 and 0.47, and the MAE values of 0.46, 0.43 and 0.37 were better than other satellite products. This satellite-derived rainfall estimates offers important advantages in terms of spatial coverage, timeliness and cost efficiency compared to analysis for drought assessment with ground stations.

2013년 가을, 한국 통영의 13개 해변에서 해양쓰레기의 풍도와 조성을 조사하였다. 대형쓰레기(25 mm 이상)의 풍도는 평균 약 30개/$m^2$, 소형쓰레기(1 mm-25 mm)의 풍도는 평균 26,971개/$m^2$로서 한국의 다른 지역이나 전세계 다른 지역에 비해 매우 높은 편이었다. 스티로폼, 경질플라스틱, 섬유, 금속, 유리, 목재, 기타 등 7개 재질로 구분했을 때 대형쓰레기 중 스티로폼의 갯수가 차지하는 비율은 약 75%, 소형 쓰레기에서는 약 98%였다. 대형 스티로폼 쓰레기 중 원래 부피의 50% 이상이 남아 있는 '완제품' 쓰레기들을 양식용 부자와 기타 완제품 쓰레기로 구분했을 때 양식용 부자가 차지하는 비율은 갯수로 93%였다. 결국 조사된 해변들에서 쓰레기로 인한 해변 오염은 매우 심각한 수준이며, 쓰레기의 발생 원인의 대부분은 양식장에서 사용되는 스티로폼 부자인 것으로 밝혀졌다. 통영 지역은 한국에서 굴 양식장이 가장 많은 곳이므로 굴 양식장의 스티로폼 부자 쓰레기 관리를 개선하는 것은 통영뿐만 아니라, 다른 지역의 해변 오염을 예방하는 데도 중요한 것으로 보인다.
