  • Objective: The Agu is the only native pig breed in Japan, which is reared in Okinawa prefecture, the southernmost region in Japan. Its origins are considered to be of Asian lineage; however, the genetic background of the Agu is still unclear. The objective of this study was to elucidate the maternal lineage of the Okinawa indigenous Agu pig with the use of the mitochondrial DNA (mtDNA) control region. Methods: The mtDNA control regions of Agu pigs were sequenced and the phylogenetic relationship among Agu, East Asian and European pigs was investigated with the use of 78 Agu individuals. Results: Twenty-seven polymorphic sites and five different haplotypes (type 1 to type 5) were identified within the Agu population. Phylogenetic analysis indicated that types 1 and 2 were included in East Asian lineages; however, the remaining types 3, 4, and 5 were of European lineages, which showed a gene flow from European pigs in the 20th century. Sixty-seven out of 78 Agu individuals (85.9%) possessed mtDNA haplotypes 1 and 2 of the East Asian lineage, which were identical to two haplotypes of ancient mtDNA (7,200 to 1,700 years before the present) excavated at archaeological sites in Okinawa. Conclusion: This study confirmed that the East Asian lineage is dominant in the maternal genetic background of the Agu population, supporting the hypothesis that the ancestors of the Agu pig were introduced from the Asian continent.

  • The Russian Far East Region covers an area of 6 Million and 216 thousands km2 and it is as vast as 36% of the Russan Federation on one hand. And this region also exists in a very severe climate condition as 90% of the region is covered with permanently frozen land on the other. This vast region has many of the world's richest natural resources : woods, fish, non-metals, energy resources, and other. The Russian Far East Region is prompts to participate in the world economy, specifically Asian and other Parcific Natiops along with the recent changes in the national structure of Russia. Although the transition to market economy and foreign investment in Russia is not sufficient, the time has come for us to actively promote technological exchanges with Korean and Russian Far East Region which are of our prosopective neighboring countries and seek for mutural relationships with us.

  • Discussion of Economic Community in East Asia are active. This trend began in the late 20th from the EU and North America's regional economic integration is in response to the movement. East Asia in the late 1990s to the actual for the FTA, it was not very active. As East Asian Economic Community became one of agendas for ASEAN+3 Leaders' meeting since 2004. Japan has been positioned itself as a leading country in East Asia. However, the emergence of China in the East Asian economic community have been changes. Moreover, East Asian countries began concerns over regional economic community with frequent conclusions of FTAs and China is leading the discussion on strengthening economic cooperation in the region. Some of it in terms of economic community in East Asia will not be smooth. First, East Asian countries do not have a common goal. Second, East Asian countries have a lot of diversity. Third, China and Japan are expected to compete in the championship. Therefore, East Asian economic community should be approached in the long-term perspective.

  • The purpose of this study is to outline the strategic implications of a structure analysis and trends of transferred air cargoes for the main airports of the North Asian region for 13 years from 2000 to 2012. To do so, it analyses the concentration levels using a Gini coefficient and Hirschmann Herfindahl index and represents the competitive positioning with regard to the main East Asian airports using the BCG framework and shift-share analysis. Currently, the concentration level is getting weaker in response to the emergence of Chinese airports in the north-east region. It is likely that the steady growth of air cargo of Shanghai airport (PVG) has caused the increase in concentration levels in the region. Seoul airport (ICN) may be directly in competition with PVG for air cargo in the region, giving consideration to reducing or maintaining an average increase ratio of air cargoes of ICN, NRT (Tokyo), and KIX (Osaka) for same period. In the same sense, the average increase in ratio for ICN for same period yields 1.3%, which is far behind the 6.2% and 5.2% of the north-east region and PVG respectively. Additionally, shift-share effect analysis indicates that ICN lost 422,180 tons in the north-east region during the same period, suggesting that transferred cargoes might have been forwarded to PVG.

  • Background The demand for aesthetic procedures continues to grow globally, particularly in East Asian countries. The popularity of specific aesthetic procedures varies, however, depending on the particular East Asian geographical region being studied. This study aimed to evaluate the experiences of and attitudes toward aesthetic procedures in five East Asian countries/regions, including China, Japan, South Korea, Hong Kong, and Taiwan. Methods To recruit participants, an online questionnaire was designed and distributed on social media networks between May 2015 and March 2016. The statistical analysis was conducted using SPSS software, version 22.0. Results A total of 3,088 people responded (approximately 600 in each country/region). Of these, 940 participants (47.8%) responded that they had experienced at least one aesthetic procedure in the past. Taiwan had the highest number of participants who had experienced at least one procedure (264/940, 41%), with primarily non-surgical experiences. Only in South Korea did surgical cosmetic experiences exceed non-surgical cosmetic experiences (55.9% vs. 44.1%). The popularity of particular procedures and the motivation for undergoing aesthetic procedures varied by country. Conclusions The popularity of aesthetic procedures continues to evolve. Similar trends were observed across the East Asian regions; however, each country had its unique demands and preferences. The information provided by this study can help aesthetic plastic surgeons further understand the patients in their corresponding region, customize their practice, and develop the requisite skills.

  • International trade environment is rapidly changing. Developing all economic activities included in the value chain of economy out of a particular country or region in the trends where globalization is spreading all over the world, 'a borderless world' has been created and become common throughout the world. Especially, in case of East Asian region, becoming the factory of the world, China has become a center of the world's economic activities in recent years; and the increase of regional investment among East Asian countries and trade expansion focused on China has been the factor of promoting the formulation of a regional trade network. SCM is an efficient way of adaptation to the complexity or uncertainty on the scene through the achievement of a sustainable competitive advantage by integrating the activities of improving the relationships in the supply chain. In this study, Sumitronics, a Japanese company, was studied as a case of the company who had implemented SCM effectively and efficiently utilizing the East Asian trade network. Not being engaged in the manufacturing processes in the headquarter, Sumitronics has implemented SCM which is capable of maximizing the responsiveness upon the requirements of customers by effective information sharing. In particular, the profits of the company have been maximized through SCM by its headquarter in Japan, which is capable of managing each base in East Asia as China and Southeast Asia, etc. Korean companies may also be able to create a new source of profit by dint of establishing SCM as such. The results of this case study has revealed that the implementation of an effective business model is the key of the successful implementation of SCM.

  • The monsoon front lies on East Asian region, but it gradually propagates to the north during the boreal summer. The equivalent potential temperature (EPT) reveals the thermodynamical features of air masses and monsoon front. Therefore, this study considered the thermodynamical EPT and dynamical wind fields to clarify the peculiarity of East Asian summer monsoon (EASM) variations in June and July, respectively. Western North Pacific subtropical high (WNPSH) and Okhotsk sea high (OSH) both play the crucial role to interannual variations of EASM frontal activity and amount of rainfall. The OSH is important in June, but the WNPSH is key factor in July. Furthermore, the OSH (June) is affected by North Atlantic tripolar sea surface temperature (SST) pattern and WNPSH (July) is influenced by North Indian Ocean SST warming.

  • This paper attempts to rethink the ancient Emperor's Capital transition process from the viewpoint of territorial history. Emperor Tenmu, who planned first capital as Fujiwara-kyo in Asuka region, had a grand plan to put multiple cities in Japan. At that time the important cities were situated along east-west axis. However, since relocation of the capital from Fujiwara-kyo to Heijyo-kyo, the axis had turned towards north-south direction. The last ancient capital Heian-kyo was clearly organized utilizing north-south water systems in territorial sense.
