North Korean leader Kim, Jung-Il visited Beijing, China, May 2010, when he made a common recognition with Chinese President Hu Jintao on construction of the Rasun SEZ and the Hwanggumpyong-Wyhwado SEZ for development of Economic cooperation between N.Korea and China and accelerating establishment of SEZs in N.Korea. However, after N.Korea's third nuclear test on Feb. 2013, the relationship between N.Korea and China became a little worse. Recently, three nations' border region near Rasun in N.Korea is reconsidered that it is very important place for collaboration between and among 2, 3 or 4 countries, S.Korea, N.Korea, China and Russia. This thesis examined these changes of cooperation and plans among the countries near the border region and proposed some measures for participation of S.Korea on the projects in the Rasun region.

The international collaboration on marine biodiversity increases in the proportion of the world's scientific papers produced with more than one international author, 2006-2010. The number of scientific papers from 2006 to 2010 describing "marine new species (or spec. nov., n. sp.)" published 401 (international ranking : $13^{th}$) by S. Korea, 824 ($7^{th}$) by China, 1,249($5^{th}$) by Japan, 1,282($3^{rd}$) by Austrailia, and 3,679 ($1^{st}$) by United States. The papers having an international co-authorship account for 52.0% by S. Korea, 79.0% by China, 67.0% by Japan, 81.0% by Australia at the same period. The proportion of national publication output produced in collaboration with other countries differs proportionately between countries. In S. Korea, the overall numbers of international collaboration were not growing significantly. Both in Japan and China, an overall numbers of international collaboration increased well in accordance with the proportion of national output with international collaboration.

This study speculates on responses to the nuclear threats of North Korea and mutual assistance and cooperation between South Korea, the U.S. and China for the unification of the Korean Peninsula. As for the North Koreas nuclear issue and unification of the Korean Peninsula, South Korea is the subject of national division, the U.S. is a responsible country in international issues and does not have diplomatic ties with North Korea. China is a traditional socialist nation and a supporter of North Korea. As North Korea's strategic weapons including nuclear weapons and ballistic missiles are international issues, to defend against Kim Jung-Eun's unexpected acts, the three countries should actively cooperate with each other and develop countermeasures. However, with respect to the road map of the North Koreas issue, there are subtle differences between the U.S. and China in recognition of and sanctions against North Korea as a resolution of the U..N. Security Council. The U.S. has continued a deterrence policy and sanctions against North Korea based on joint threats between South Korea and the U.S. while China has showed a negative position in the process of solving the North Korean nuclear issue because of the unstable security derived from the U.S. 's intervention in the Korean peninsula. North Korea should change its diplomatic policy in a more concrete way towards world peace although it has continued trade of strategic weapons with Middle Eastern countries to maintain its political system. For example, to restart the summit talks and open multilateral security channels. Although the issue of unification of the Korean peninsula should be resolved by South and North Korea themselves, it is strange that South and North Korea depend on the logic of powerful countries for the resolution of a national problem. As for North Koreas nuclear and the Unification issues, peaceful solutions presented by South Korea seem more persuasive than the solution presented by North Korea which did not secure any international support. However, South Korea, the U.S. and China need to develop uni-directional two-tract strategies for sanctions against North Korea and talks with North Korea for peace on the Korean peninsula, and should continue to support the economic independence of North Korea.

Entrepreneurship has been received enormous attention all around the world in terms of economic prosperity of local society and a nation. This paper explores the critical factors which influence entrepreneurship, particularly how role models affects social competence and entrepreneurship of Korean and Chinese university students. Total 440 students participated in the study; Korea(n=224) and China(n=216). Verifying mediating effect of social competence was another aim of this study. Four hypotheses were suggested to assess the extent to which they prove the students' perceptions with hierarchical multiple regression analysis(PASW Statistic 18). Our findings showed that role models have positive relationships with social competence as well as entrepreneurship. Social competence influences entrepreneurship significantly, too. Social competence has also a partial mediating effect in relationship between role models and entrepreneurship. We presented both theoretical contribution and practical implication for school authorities and policy makers as to the effective pedagogy for promoting entrepreneurship of university students.

Using webometric big data, this study examines the diversity of online information sources about the novel coronavirus causing the COVID-19 pandemic. Specifically, it focuses on some 28 countries where confirmed coronavirus cases occurred in February 2020. In the results, the online visibility of Australia, Canada, and Italy was the highest, based on their producing the most relevant information. There was a statistically significant correlation between the hit counts per country and the frequency of visiting the domains that act as information channels. Interestingly, Japan, China, and Singapore, which had a large number of confirmed cases at that time, were providing web data related to the novel coronavirus. Online sources were classified using an N-tuple helix model. The results showed that government agencies were the largest supplier of coronavirus information in cyberspace. Furthermore, the two-mode network technique revealed that media companies, university hospitals, and public healthcare centers had taken a positive attitude towards online circulation of coronavirus research and epidemic prevention information. However, semantic network analysis showed that health, school, home, and public had high centrality values. This means that people were concerned not only about personal prevention rules caused by the coronavirus outbreak, but also about response plans caused by life inconveniences and operational obstacles.

From 1994 the cooperation between NEU of China and MJU of South Korea for study of ReBaCuO (Re=Rare earth elements) superconductors has been carried out. The progress has been got in following projects. Critical current density ($J_c$) of YBaCuO superconductor prepared by Melting Textured Growth (MTG) was improved. In the preparation of textured YBaCuO, 20 wt.% of YBaCuO 211 phase was added, which would be climactic for the microcracks in the textured YBaCuO. The effects of the 211 phase and Ag content on the superconductivity were studied and discussed in detail. The improved $J_c$ value was reached to 8$\times$10^4 A/cm^2 (77K,0T). Single phase $YbBa_{2}Cu_{3}O_{x}$ superconductor was sintered by the traditional powder metallurgical method, and its reaction process was studied. In recent years, NdBaCuO superconductor is being performed. The behavior of $Nd_{4}Ba_{2}Cu_{2}O_{10}$(Nd422 phase) and the solid solubility, x in the superconductor $Nd_{1+x}Ba_{2-x}Cu_{3}O_{y}$ by the heat treatment in the low oxygen partial pressure (1%) or Ar at $950{\circ}C$ were investigated. The zone-melting process was used to make oriented NdBaCuO superconductor in order to increase the critical current density.

Since the introduction of Israeli carp into Korea for farming in 1973, there are no breeding studies on developing Korea Israeli carp (domestic) so far. This study performed gene-based cross-breeding studies to restore genetic diversity of lowered Israeli carp through continuous inbreeding, and for rapid growth and better scales. This study produced four cross-breeding groups (F1) using Koean Israeli carp and Chinese Songpu mirror carp for the improvement of growth and scale of Israeli carp in Korea. And mating scheme for breeding groups was set in consideration of the morphological analysis and genetic distance of broodstock. In addition, this study used microsatellite markers and genotype data to analyze genetic diversity and parentage analysis. As a result, the average N_A and H_E values of Korean select broodstock are 8.3 and 0.743, and F1 is 13.0 and 0.764. This study shows that the genetic diversity of F1 has been recovered over Korean Israeli carp through breeding between Korean Israeli carp and Chinese Songpu mirror carp. Common Israeli carp in Korea reached 1.7 kg in 17 months, and improved Israeli carp reached to 2.2 kg. The KC (Korea×China, KC) group was 2.52 and broodstock group was 3.15. F1 showed lower scale score (0.63) than broodstock. The improved carp (F1; CK, KC) had 20% better scales than the parent group (F0), which improved 27% in weight and 25% in scales compared to common Israeli carp. The Israeli carp developed by the genetics-based breeding grew quicker and had improved genetic diversity and fewer scales, which will be of great value for Korean Israeli aquaculture industry due to good marketability.
