The war between Ukraine and Russia continues. Ukraine, with the help of the United States and others, is fighting a superior battle against Russia with advanced weapons applied artificial intelligence. In line with this trend, the Korean military announced Defense Innovation 4.0 to expend investment in defense technology for the 4th Industrial Revolution and to realize a smart military. In order to achieve this effectively, it is necessary to examine the weapons R&D system. This thesis examines the existing weapons research and development system and derives the plans that can rapidly develop Advanced weapons in a timely manner. In addition, the plans for Rapid R&D for the application of the recently introduced 4th industrial revolution technology was also presented. Through this, it was intended to help the Korean military quickly adopt Advanced weapons in the future.

Siberian flying squirrel, an endangered species in South Korea, is distributed through major mountain regions of South Korea. The number of Siberian flying squirrel(Pteromys volans) in South Korea has decreased and their habitats are fragmented and isolated because of anthropogenic activities. So far no molecular genetic data has, however, been available for their conservation and management. To obtain better information concerning genetic diversity and phylogenetic relationships of the Siberian flying squirrel in South Korea, we examined 14 individuals from South Korea, 7 individuals from Russia, and 5 individuals from northeastern China along with previously published 29 haplotypes for 1,140 bp of the mtDNA cytochrome b gene. The 14 new individuals from South Korea had 7 haplotypes which were not observed in the regions of Russia and Hokkaido. The level of genetic diversity(0.616%) in the South Korean population was lower than that in eastern Russia(0.950%). The geographical distribution of mtDNA haplotypes and reduced median network confirmed that there are three major lineages of Siberian flying squirrel, occupying; Far Eastern, northern Eurasia, and the island of Hokkaido. The South Korean population only slightly distinct from the Eurasia, and eastern Russian population, and is part of the lineage Far Eastern. Based on these, we suggest that the South Korean population could be considered to belong to one partial ESU(Far Eastern) of three partial ESUs but a different management unit. However, the conservation priorities should be reconfirmed by nuclear genetic marker and ecological data.

Mongolia is located between Russia and China in Central Asia. In coal-rich corners, both the energy and energy sectors of our country prevail. Mongolia has vast resources of renewable energy and limited hydropower plants, such as wind and solar. In their first iNDC (intended Nationally Determined Contributions) submitted in 2015, Mongolia has pledged to increase the share of renewables capacity to 20% by 2020, and 30% by 2030 while reducing their energy related GHG emissions.

최근 농촌관광의 개념이 확대되고 농촌관광의 시장규모가 점점 커지고 추세이다. 이러한 추세를 반영하여 러시아 극동지역 정부에서는 광활한 농업적 생태환경에 근거하여 인접국가와 관광교류을 통한 지역경제의 활성화를 정책적으로 추진하고 있다. 농촌관광에 관한한 30년의 추진경험을 갖고 있는 한국은 이러한 추세에 맞추어 한-러 양측의 상호 보완성에 입각한 협력과 수요변화에 대응한 농촌상품을 개발을 통하여 양국간 관광협력시 많은 가능성을 보여줄수 있다.

From Cold War, Nuclear weapons have emerged military power into a very dangerous and important way of each national security. Throughout the era, the U.S. had stationed nuclear weapons in South Korea. But President George Bush initially started the withdrawal of nuclear tactical weapons deployed abroad in 1991. After that, under the protection of the nuclear umbrella, South Korea guarantees that the United States would operate its nuclear weapons to protect South Korea if it would be needed and the economy of South Korea has rapidly developed as more strong countries in the world. However, South Korea has seen and been realized the present state from the recent war between Russia and Ukraine. The protection of the U.S. nuclear umbrella from nuclear weapons and ballistic missiles of North Korea is unlikely to be permanently guaranteed. At the same time, South Korea should consider the security environment changes of surrounding nations such as China as military power acceleration and Russia as re-formation ambition. Because of these reasons, South Korea independently wants to protect itself and have the own nuclear weapons as a way to counter security threats. A majority of South Koreans also definitely believe that North Korea will not denuclearize or give up because North Korea has been having nuclear weapons as the final survival strategy of Kim Jong Un's regime. However, South Korea considers and makes new nuclear strategy through the role and effect of nuclear deterrence strategy in dispute between India and Pakistan and how to overcome the paradox of nuclear deterrence strategy. Therefore, this research is to suggest the effective nuclear deterrence strategy of South Korea from new security threats of surrounding nations through dispute between India and Pakistan. The focus of this research is that what is the role and paradox of nuclear deterrence strategy in dispute between India and Pakistan and how to find the effective nuclear deterrence strategy of South Korea.

Asiatic black Bear(Ursus thibetanus ussuricus) cubs aged one or two were introduced from Russia(Primosky krai) and North Korea for reinforcement of the bear population and they were released to grow wild in Jirisan National Park. We did research on the characteristics of the denning sites of the Asiatic black cubs, which were released before, from Oct. 2004 to Apr. 2006, and the results were as follows: The released bears hibernated in three types of dens,; tree hollows, rock hollows or ground nests. The hibernating sites were dominated by a community of oak trees and its location was at an average of $923{\pm}221m$ height above the sea level ; the average slope incline was $25.9{\pm}7.9^{\circ}$, and the average denning duration was $98{\pm}9$ days. It was analyzed that the cubs' denning site was $2.8{\pm}2.8km$, on an average, far from the release point; $2.0{\pm}0.9km$ far from villages; $1.9{\pm}1.7km$ far from park inspection trails, and $1.9{\pm}1.0km$ on the average far from a driveway. It is assumed that environmental attributes of the denning sites were closely correlated to those of the release points.

So far, the main threat to South Korea was North Korea. That is why South Korea established a strategy based on the threat of North Korea and most of the budget on defense was used to deter North Korea. Even though the neighboring countries(China, Japan, and Russia) are growing as a real threat with abilities and intentions based on their powerful naval forces, South Korea has not yet been able to establish a strategy that regards neighboring countries as a threat. But the decades-old structural mechanism of the Korean security environment is undergoing a radical change on April 27, 2018, through the South-North summit and the Panmunjom Declaration. Under the changing security environment, South Korea was placed in a complicated dilemma that had to deal with threats of two axes(China), three axes(China, Japan), and four axes(Japan, Russia). If the one axis threat(North Korea) is dominated by land threats, the second, third and fourth axis threats are threats from the sea. This paper analyzed the maritime strategy of Korea within the framework of maritime-geopolitics, in other words recognition and expansion of the sphere of maritime. I have designed that the maritime defense space that we can deny from threats is divided into three lines of defense: 1 line (radius 3,000km), 2 lines (2,000km), and 3 lines (1,000km). The three defense zones of the three lines were defined as an active defense(1 line), defensive offense(2 line), active offense(3 line). The three defense zones of the three lines were defined as the sphere of core maritime, As a power to deny the sphere of core maritime, it was analyzed as a maneuvering unit, a nuclear-powered submarine, the establishment of missile strategy, and the fortification of islands station. The marine strategy of South Korea with these concepts and means was defined as 'Offensive Maritime Denial Strategy'.

The primitive beachflea, Paciforchestia pyatakovi (Derzhavin, 1937) living in gravel beaches was previously reported only from Japan and Russia. This species can be easily distinguished from another species in the same genus, P. klawei (Bousfield, 1961), by the degradation of all plepods and both rami that each consist of single article bearing 2-4 distal plumose setae. Descriptions of the diagnostic characteristics of the species are presented.
