Five Islands in the West Sea of Korea (Baekryeong-do, Daecheong-do, Socheong-do, Yeonpyeong-do, and Woo-do) are located very close to the North Korea's coast and all of them are under the jurisdiction of South Korea. The North and South Korean naval vessels clashed twice in the West Sea of Korea on June 15, 1999 and on June 29, 2002. These incidents were resulted from conflicts over the validity of the Northern Limit Line(NLL) and the appropriate maritime boundary between the two Koreas. From the viewpoint of South Korea, the North Limit Line is a lawful Maritime Military Demarcation Line under the Korean Military Armistice Agreement and it must be maintained as a maritime boundary between two Koreas until being substituted by a peace treaty. In conclusion, the maritime boundary between two Koreas cannot be settled easily by the principles of the International Law of the Sea at present.

After successful nuclear tests Pakistan launched a more severe surprise attack toward India than before. It is highly possible that North Korea will adopt this Pakistan military strategy if it is armed with nuclear weapons. The North Korean forces armed, with nuclear bombs could make double its war capability through strengthening aggressive force structure and come into effect on blocking reinforcement of the US forces at the initial phase of war time. Therefore we may regard that Pyongyang's nuclear arming is a major one of various factors which increase possibility of waging a conventional warfare or a nuclear war. North Korea's high self-confidence after nuclear arming will heighten tension on the Korean Peninsula via aggressive military threat or terror toward South Korea, and endeavor to accomplish its political purpose via low-intensity conflicts. For instance, nuclear arming of the Pyongyang regime enforces the North Korean forces to invade the Northern Limit Line(NLL), provoke naval battles at the West Sea, and occupy one or two among the Five Islands at the West Sea. In that case, the South Korean forces will be faced with a serious dilemma. In order to recapture the islands, Seoul should be ready for escalating a war. However it is hard to imagine that South Korea fights with North Korea armed with nuclear weapons. This paper concludes that the Pyongyang regime after nuclear arming strongly tends to occupy superiority of military strategy and wage military provocations on the Korean Peninsula.

1953년 7월 27일 한국정전협정 체결시 육상에서의 경계는 쌍방 간의 군사 접촉선을 중심으로 군사분계선이 합의되었으나 해상경계에 관하여 아무런 근거규정을 두고 있지 않다. 다만 정전협정 제2조 13항목에서 "백령도 등 서해 5도만 유엔군 사령관 통제 하에 둔다"라는 내용만 명시되어 있을 뿐이다. 이러한 입법적 흠결로 북한은 서해북방한계선을 비합법적인 선으로 그 법적 효력을 부인하고 있다. 그러나 서해 북방한계선은 1953년 8월 30일에 유엔군과 한국군의 북쪽 해상으로 월선(越線)을 방지하기 위해 설정되었다. 간헐적으로 무력충돌은 있었으나 쌍방 간의 무력적 충돌방지역할은 물론 평화와 군사적 안정을 유지시켜 온 사실상 남북한 간의 해상경계선이다. 특히 서해 북방한계선은 한국해군에게 북한의 해주 및 옹진반도, 장산곶을 연하는 해역을 통제함으로써 북한 해군의 활동 영역을 제한시키고 있기 때문에 대한 민국의 안보에 중대한 역할을 하고 있다. 따라서 북한은 서해5도의 주변 해역을 자기들의 영해라고 주장하지만 서해5도를 위시하여 38도선 이남에 있는 영역과 섬들은 대한민국이 주권을 중단 없이 행사해온 곳이다. 우리는 실효적 지배를 강화함으로써 서해북방한계선에 대한 영토관할권 행사를 해야 할 것이다.

Northeast Asia has a multi-layered security structure within which major economic and military powers both confront one another and cooperate at the same time. Major regional powers maintain mutually cooperative activities in the economic sphere while competing one another in order to secure a dominant position in the politico-military arena. The multifarious threats, posed by the North Korea's nuclear development, territorial disputes, and maritime demarcation line issues demonstrate that Northeast Asia suffers more from military conflicts and strifes than any other region in the world. Specifically, major maritime security threats include North Korea's nuclear proliferation and missile launching problems as well as military provocations nearby the Northern Limit Line(NLL) as witnessed in the Cheonan naval ship and Yeonpyong incidents. The ROK Navy has been supplementing its firm military readiness posture in consideration of North Korea's threats on the NLL. It has performed superb roles in defending the nation and establishing the Navy advanced and best picked. It also has been conducive to defend the nation from external military threats and invasion, secure the sea lanes of communications, and establish regional stability and world peace. In order to effectively cope with the strategic environment and future warfares, the ROK Navy needs to shift its military structure to one that is more information and technology intensive. In addition, it should consolidate the ROK-US alliance and extend military cooperative measures with neighboring countries in the Asia-Pacific region. Evolved steadily for the last 60 years, the ROK-US alliance format has contributed to peace and security on the Korean peninsula and in the Northeast Asian region. In conclusion, this manuscript contends that the ROK Navy should strive for the establishment of the following: (1) Construction of Jeju Naval Base; (2) Strategic Navy Equipped with War Deterrence Capabilities; (3) Korean-type of System of Systems; (4) Structure, Budget and Human Resources of the Naval Forces Similar to the Advanced Countries; and (5) Strategic Maritime Alliance and Alignment System as well as Domestic Governance Network for the Naval Families.

서해 북방한계선에 관한 논쟁은 1953년 8월 유엔군사령관이 한반도 해역에서 남북간의 우발적 무력충돌을 예방한다는 목적으로 설정한 이후부터 지금까지도 첨예하게 대립하고 있는 문제이다. 2022년에는 분단이후 최초로 NLL이남으로 북한이 미사일 도발을 한 바 있다. 이처럼 북한의 실질적 도발이 진행중인 NLL에 대한 연구는 어떻게 진행되어 왔는지 확인해보고 나아갈 방향제시를 하는데 본 연구의 목적이 있다. 본 연구는 1998년부터 2023년까지 NLL에 관해 연구된 학술논문을 중심으로 RISS, 스콜라 등 총 5개의 학술정보 DB를 활용하여 연구의 경향을 살펴보았다. 연도별, 분야별, 연구 방법별 현황을 살펴본 결과 연도별로는 정부별 대북관계 기조에 따라 연구량의 유의미한 차이를 확인할 수 있었으며, 연구 분야는 NLL에 대한 개념소개와 역사적 배경 등이 가장 많아 힘의 논리에 따라 변화하는 국제 환경을 고려할 때 NLL의 국제법적 당위성과 명분을 구비하기 위해 더욱 다양한 분야로 확대될 필요성을 확인했다. 마지막 연구방법면에서는 문헌연구가 대부분이어서 면접, 설문, 빅데이터 등을 활용한 양적연구 등의 필요성도 알 수 있었다. 이러한 본 논문의 분석결과가 현재도 여전히 진행중인 국제정치환경의 이해관계 속에 향후 NLL의 국제적인 대응을 위한 연구방향설정에 긍정적인 역할을 하길 기대한다.

본고의 목적은 히라타 오리자의 세 희곡, 과학하는 마음, 북방한계선의 원숭이, 발칸동물원을 리오타르의 포스트모던 과학관으로 분석하는 데 있다. 과학과 서사가 각기 독자적인 화용법의 규칙을 따른다고 주장하는 리오타르는 둘 사이의 공약 불가능한 평행성을 이야기한다. 히라타 오리자는 이러한 포스트모던의 세계에서 인간이 서사에 의지하는 양상을 짚어 낸다. 본고는 히라타 오리자의 희곡을 세 가지 측면에서 분석한다. 첫 번째는 거대 서사가 사라진 포스트모던의 세계에서, 방향을 잃고 발달하는 과학 기술 아래 인간이란 존재의 정체성을 규정하는 경계가 희미해지는 지점을 확인한다. 두 번째는 서사에 기대어 세계를 이해하는 인간의 특성으로 인해, 과학 지식과 서사 지식의 평행성이 끊임없이 희석되는 양상을 살펴본다. 끝으로 거대 서사가 사라지고 수행성의 최대화만으로 정당화되고 있는 세계를 향해, 개인이 스스로의 위로로 제기하는 작은 서사의 양상을 파악한다.

This study analyzed the status of climate-change indicator plants native to the main islands of the Korean peninsula, while elucidating their distribution characteristics. Information on flora from over 129 island locations, comprising more than 100 species of native plants, was collected, compiled into a database, and utilized as raw data. The distribution of 193 climate-change indicator plants was confirmed. The distribution area of broadleaf evergreen trees and ferns, including Mallotus japonicus and Cyrtomium falcatum, was relatively wide. In contrast, the distribution of common northern plants such as Corydalis turtschaninovii and Malus baccata was limited. If global warming persists, northern plant distribution is expected to decrease rapidly in the Korean Peninsula island region, while the northern limit line of the southern plants is expected to migrate further northward. During this process, it is likely that the plant congregation structure and species diversity within the island region will change dynamically. In this study, comparative analyses between species and regions were conducted by assessing the relative frequency of their occurrence, and six types of botanical geographic distribution patterns were noted.

The Han River is divided into North and South Korea by NLL(Northern Limit Line) and its area has been blocked by CCL(Civil Control Line) since the Korean War in 1950. Satellite remote sensing, therefore, is uniquely suited to monitoring bar transformation in the region. In river with bar, the characteristics of its physical conditions have a close relationship with bar morphology. In this paper, a monitoring approach of bar transformation in the Han River Estuary is presented using RADARSAT/SAR images from 2000 to 2005 and spatial patterns of bar morphology are presented. it could be said that in the estuary vegetated area and natural levees are developed well, but bars are shifted after an event like a flood. It is also showed that suspended solids such as silt transported through the estuary could contribute highly to a sedimentation environment around Incheon.

Unmanned surface vehicles(USVs) have been developed for special operations in foreign navies. These will be employed to conduct critical missions including inspection, coast guard, ISR, fire protection, precision strike, mine interception warfare and antisubmarine warfare. It is also known the USVs will be deployed at the front line of the network-centric warfare to replace the manned naval operations. The unmanned operation can, thus, minimize unnecessary risk to personnel and enhance the success probability for the imposed mission. In this research, the USVs which are under operation and development in foreign navies are investigated. Based on this, an USV with $7\~10m$ of length and 10ton of weight for the Korean Navy which can be deployed near the Northern Limit Line(NLL), is proposed.

Two species of Moroco oxycephalus and M. lagowskii were studied to examine patterns of genic variation and morphological difference within and between populations of two species, and to clarify their taxonomic status and geographic distribution. The number of scales above lateral line(SAL) was the key character to classify these species. On the average, M.lagowskii had 22 or more SAL whereas M.oxycephalus had 20 or less. Previously known character of the position of dorsal fin was found to be not appropriate to distinguish them. Five loci, Gp, st-1, Est-2, Est-3 and Got-1 , showed fixed difference electrophoretically between two species and these could be used as genetic markers to identify them. The degree of genic variation of M. oxycephalus was four fold higher(H=0.032) than that of M. lagowskii(H=0.008) but both species were far less than the average genic variation of freshwater fish in general. Rogers' genetic similarity coefficients between two species were S=0.692 and their presumed divergent time was estimated to be sbout 1.8million years ageo. Detailed survey of the geographic distribution of thses revealed that M.lagowskii was distributed in northeastern part of South Korea(Ganseong , Gangreung, Wangsan, and Oggye) and M. oxycephalus was occupied rest of the peninsula. The distrance between Oggye, the southern limit of M. lagowskii distribution , and Samwha (near Samcheog), the northern limit of M.oxycephalus, was aobut 15 Km apart and no symparty was found in between.
