Dominant mechanisms of the sintering of copper nano-powders depending on the crystal misalignment
Seong, Y.,Kim, Y.,German, R.,Kim, S.,Kim, S.G.,Kim, S.J.,Kim, H.J.,Park, S.J. Elsevier 2016 Computational materials science Vol.123 No.-
Sintering mechanisms of nanoscale copper powder are investigated using molecular dynamics (MD) simulations based on the embedded-atom method (EAM). The densification parameters, such as shrinkage, and relative sintered density are calculated using the two-particle sintering model. This paper considers the important role of crystalline misalignment between two particles on densification. Besides volume diffusion contribution, misalignment between the crystal structures results in enhanced grain boundary diffusion. At low temperatures, grain boundary torque cause particles to rotate to reduce grain boundary energy. At higher temperatures, particle rotation becomes complicated including remarkable twist, and grain boundary tilting due to grain-boundary-like diffusion. These results provide insights to the processing cycle parameters applicable to nano-powders.
Migration vs. Repatriation to South Korea in the Past and Present
( German Kim ) 대한민국역사박물관 2017 Journal of Contemporary Korean Studies Vol.4 No.1
South Korea achieved an economic miracle in the last third of the twentieth century and has evolved from a kin state into a host state of international migration. Repatriation of compatriots in the Republic of Korea, as a type of international migration, has its specific characteristics because there is another country―North Korea―which was also involved in cross-border population movements. Based on the growing number of migrants, including chosonjok from China, koryoin from the Commonwealth of Independent States (CIS) countries, primarily Russia and Uzbekistan, and thalbukja, refugees from North Korea, and the reverse migration of overseas Koreans from the United States and other Western countries, the main agenda is repatriation legal support and effective programming for integration into mainstream South Korean society. Repatriates may affect the stability and development of South Korea in the twenty-first century. An investigation of the basic stages of repatriation, of its constituent elements, the problems encountered in the adaptation of immigrants in the modern Republic of Korea, assumes knowledge and consideration of the migrant`s experience, reception, and understanding of national repatriation programs. This article is an attempt toward comparative diachronic and synchronic analysis of Korean repatriation as a type of international migration.
The Correlation of a Global Korean Commonwealth with the Confederation vs Reunification of Korea
German Kim 건국대학교 아시아·디아스포라 연구소 2021 International Journal of Diaspora&Cultural Critici Vol.11 No.1
The year 2020 marked the 30 th anniversary of the establishment of diplomatic relations between Russia (Soviet Union) and the Republic of Korea. Despite plenty of differences in ideology and policy, Moscow and Seoul are trying to realize a similar project on the formation of global communities of compatriots known as “Russkiy Mir” 1 and “Global Korean Commonwealth.” However, Russia is preoccupied with preserving the unity of the federation and numerous inhabiting ethnoses. Korea, in its turn, attempts to create a confederation of the two Korean states with the following reunification of the country. This paper studies the notion of the “Global Korean Commonwealth” meaning the union of North and South Koreans plus all Koreans living abroad and compares it with such quasi-terms as “Korean super ethnos” and “Korean meta-nation” invented by Russian-speaking philosophers. As the formation of the Global Korean Commonwealth is based on a hypothetical unified Korea, the paper is considering concepts of the reunification and the role of Korean Diasporas in inter-Korean relations.
Anthroponymy of the Koryo Saram
KIM, German 단국대학교 한국민족학연구소 1993 한국민족학 연구 Vol.- No.1
In total, the mumber of Koreans who lived in the former USSR, according to the 1989 Census, was 439 thousands, the great bulk of whom live in Uzbekistan, Russia and Kazakhstan. The modern demography of the Korean populations in characterized by dispersion; this demography is a legacy of the policy of forced migration during the Stalin epoch, and also by processes of migration and infiltration among the Korean populations.
