  • 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.

Reassessment of the Taxonomic Status of the Bemisia tabaci Complex (Hemiptera: Aleyrodidae) Based on Mitochondrial COI Gene Sequences (미토콘드리아 COI 유전자 분석을 통한 담배가루이 종복합군의 분류학적 재평가)

  • Bemisia tabaci (Hemiptera: Aleyrodidae) is one of the most important insect pests in the world. In the present study, the taxonomic status of B. tabaci and the number of species composing the B. tabaci complex were determined based on 550 COI gene sequences of B. tabaci. Genetic divergence within B. tabaci ranged from 0% to 27.8% (average 11.1%). This result indicates that the B. tabaci complex is composed of multiple species that may belong to different genera or subfamilies. A phylogenetic tree constructed based on 217 COI gene sequences without duplications revealed that the B. tabaci complex is composed of a total of 43 putative species, including a new species, Java. In addition, genetic divergence within nine species (Australia, Asia II 1, Asia II 6, Asia II 7, Asia II 10, Mediterranean, New world, New world 2, Sub Saharan Africa 1) indicates that 4.0% is reasonable to be used as a threshold of species boundaries within the B. tabaci complex, and species with high intraspecific genetic divergences can be related with cryptic species.

The Study on the Origin of Soybean Cultivation (대두재배(大豆栽培)의 기원(起源)에 관한 고찰(考察))

  • According to the literature, soybean cultivation originated from Wang-Gong (B.C. 685-643) of China who brought it from northeast Asia, for the first time. FUKUDA, of Japan divided soybean into three species-the wild, the cultivated and the intermediate. From the result of that study, he concluded that the soybean originated in northeast Asia. But Wang Kum Rung of China insisted that soybean originated in Hwa-Nam, because the soybean is a shortday plant and the agricultural history of Hwa-Nam, south of China, is older than that of northeast Asia. However, agriculture in northeast Asia had been already begun about B.C. 4000-6000 and the origin of culture cannot be decided only by photosensitivity. It has been proved that soybeans found in Korea were same as the ones of B.C. 2000. The soybeans of northeast Asia meet the conditions of the probable place of origin of cultivated crops established by Vabilov. Accordingly it is concluded that soybean has been originated from northeast Asia.

The Sogdian Descendants in Mongol and post-Mongol Central Asia: The Tajiks and Sarts

  • This paper is devoted to the examination of the identity of the Sogdian descendants and their historical role in the second millennium CE. More specifically, it discusses the Sogdian connection to the later Iranic-speaking peoples of Central Asia, namely, the Sarts and the Tajiks. It then discusses the symbiotic relationship between the Sogdian descendants and the Mongols and the Mongol descendants (Chaghatays and Uzbeks) in Central Asia. In sum, this paper argues that the Sogdians did not perish after the Arab conquest of Central Asia in the eighth century CE. They survived under new exonyms Sart and Tajik. Like the Sogdians in pre-Islamic Central Asia, the Tajiks or Sarts played important historical roles in the Mongol and post-Mongol states of Central Asia, maintaining a symbiotic relationship with the nomad elites.

  • Trends toward an influx of new migrants have been pronounced in East Asia through a development we call the third round of migrant incorporation. At the same time, other features of East Asian societies, such as strong levels of ethnic nationalism, have changed little, posing challenges to multiculturalism. In this introduction to this special issue, we review the latest research trends broadly concerning multiculturalism, migrant groups that have received little attention, racism and xenophobia. We first discuss the state of migrant incorporation in East Asia and the limits of multiculturalism in this region, where various features of the developmental state persist. We then introduce research on voices opposing multiculturalism in East Asia. This introduction highlights what is peculiar―and ordinary―about migrant incorporation and the associated challenges in East Asia.

  • The paper examined Southeast Asia as a whole and focused on similarities among countries composing what is now known as the Association of Southeast Asian Nations (ASEAN). In order to determine these similarities, the analysis focused on the fact that during World War II the whole of Southeast Asia was occupied by one political power: Japan. The policies the Japanese implemented in the region were to a degree very similar in terms of pressures and tensions that occurred in the different countries. The paper argues that these pressures and the responses of the various peoples of Southeast Asia instilled a nucleus of common identity in Southeast Asia as a whole. Basically, the policies that the Japanese implemented all over Southeast Asia were the following: the setting up regional administrations; the extraction of resources and emphasis on local self-sufficiency; the implementation of cultural Japanization; and local indigenization policies. The Southeast Asian responses that crystalized this joint Southeast Asian identity may be described as: accommodating and resisting the Japanese; commemorating portraying; and collectively remembering the era. The process of action and reaction between Japan and Southeast Asia was formative of this joint Southeast Asian identity.

  • The paper discusses how the new EU Strategy towards Central Asia issued in May 2019 might be analyzed through the lens of the intensely debated transformations from the liberal to a post-liberal international order. The author claims that the EU's normative power is transforming from the post-Cold War predominantly liberal/ value-based approach, with democracy and human rights at its core, to a set of more technical tools and principles of good governance and effective management of public administration. The paper problematizes a nexus between the dynamics of the EU's nascent post-liberalism and the geopolitical challenges of the EU's growing engagement with illiberal regimes, focuses on direct encounters between the post-liberal EU and the illiberal elites in Central Asia, and seeks to find out the impact of these connections upon the EU's international subjectivity. In this context geopolitical dimensions of EU foreign and security policies, along with the specificity of the EU's geopolitical actorship in Central Asia, are discussed.
