Until recently, Pacific equatorial tropical island states were subject of only very limited interest by scientists, government officials, industry and policy makers of Korea. And, comprehensive information and data on these island regions is not very detailed to help better understand their social backgrounds as well as their natural environment. However, these island regions are now in the middle of diplomatic tug-of-war among super powers as well as becoming nucleus of various science-based ocean issues including marine biodiversity, shifting ecosystem, global environmental change including sea level rise and ocean acidification, fisheries, etc. Therefore, rising political and scientific importance of these areas call for better understanding of these regions, in social aspects as well as natural scientific knowledge of the region. To be provocatively prepared to more actively role in these regions, "A study on Establishing Research Infrastructures in the Tropical Pacific" has been supported during 2012-2013 as a mission-oriented in-house project of the KIOST. This project aims to provide various research infrastructure for Pacific island states, to reinforce cooperation with these nations, and to enhance Korea's national prestige. This special issue contains 10 research articles based on the studies conducted in 2012~2013.

"Ubiquitous sensor network" definition is this-Someone attaches electro-magnetic tag everything which needs communication between man to man, man to material and material to material(Ubiquitous). By using attached every electro-magnetic tag, someone detects it's native information as well as environmental information such as temperature, humidity, pollution and infiltration information(Sensor). someone connects it realtime network and manage generated information(Network). 21st century's war is joint combined operation connecting with ground, sea and air smoothly in digitalized war field, and is systematic war provided realtime information from sensor to shooter. So, it needs dramatic development on watch reconnaissance, command and control, pinpoint strike etc. Ubiquitous computing and network technologies are essential in national defense to operate 21st century style war. It is possible to use many parts such as USN combined smart dust and sensor network to protect friend unit as well as to watch enemy's deep area by unmanned reconnaissance, wearable computer upgrading soldier's operational ability and combat power dramatically, RFID which can be used material management as well as on time support. Especially, unmanned watch system using USN is core part to transit network centric military service and to get national defense efficiency which overcome the dilemma of national defense person resource reducing, and upgrade guard quality level, and improve combat power by normalizing guardian's bio rhythm. According to the test result of sensor network unmanned watch system, it needs more effort and time to stabilize because of low USN technology maturity and using maturity. In the future, USN unmanned watch system project must be decided the application scope such as application area and starting point by evaluating technology maturity and using maturity. And when you decide application scope, you must consider not only short period goal as cost reduction, soldier decrease and guard power upgrade but also long period goal as advanced defense ability strength. You must build basic infra in advance such as light cable network, frequency allocation and power facility etc. First of all, it must get budget guarantee and driving force for USN unmanned watch system project related to defense policy. You must forwarded the USN project assuming posses of operation skill as procedure, system, standard, training in advance. Operational skill posses is come from step by step application strategy such as test phase, introduction phase, spread phase, stabilization phase and also repeated test application taking example project.

The maritime blockade has long been used as a means of war in that it serves as a bridge for economic warfare by paralyzing enemy maritime transport, although it is not a decisive battle, and in the Korean War, U.N. forces have achieved significant results in the war with limited maritime blockade through the Clark Line. However, with China emerging as a maritime powers based on its strong naval power, there is a lack of consideration on how to set up a blockade to block maritime activities and how to respond neutral ships or carrying wartime contraband products if war breaks out again on the Korean Peninsula, In addition, since maritime blockade should be used as a sensitive and flexible naval force projection in that it has interests with neutral countries, it should be carefully reviewed in that it can be used only through careful and reasonable judgment considering the principle of ensuring the legality of maritime blockade Therefore, in this study, Reexamine the process of change in the application of the International Law of Blockade, and through this, Derive the basic principle of ensuring the legitimacy of maritime blockade. In addition, by reviewing the application of these basic principles in the waters off the Korean Peninsula at wartime, we presented answers to research questions by reviewing what needs to be done to neutral ships and ships carrying wartime contraband products, and considered the implications for us

The construction of Jeju Naval Base was finally completed and donated to the Republic of Korea Navy on February 26th this year. There is no doubt that the new base will contribute to the substantial augmentation of Korea's naval power and maritime security. However, we should note that the new naval base took a long and hard twenty-three years to be completed. In the 21st century, Korea should adopt a new strategy that can fulfill the security requirements of Korea for the new age of international relations. The 21st century is characterized by globalization, and in the world of globalization, a national boarder has become meaningless. In the late 20th century, after the Cold War, trade between countries have greatly increased and so did the importance of the seas. Having transformed from an agricultural country into a commercial country, Korea went from a continental state to a maritime state. Korea has become the 9th largest trading state, and obviously, the importance of the sea has become significant. Korea's national strategic focus needs to be on the sea for national survival. Thus, since the 1990s, the Korean Navy has planned to build the Jeju Naval Base. Jeju, due to its geopolitical characteristics, is extremely important to the 21st century Korea's economy and national security. Jeju is the starting point of the sea route that reaches out to the world, and at the same time, the ending point of the sea route that heads towards Korea. Jeju is located in the center of Northeast Asia and thus, Jeju Naval Base is extremely important for the area's security and order. Jeju Naval Base will be very useful not only for the maritime security of Korea, but also for keeping peace and order in Northeast Asia. Jeju Naval Base was the minimal effort against the six sea route security threats towards Korea. The six sea route threats are: 1) Threat from North Korea; 2) China's Threat towards Korea's sovereignty; 3) China's treat towards Korea's fishery; 4) Threat from Japan; 5) Threat towards Korea's sea routes; 6) Threat from recent phenomena of isolationism of the United States. Jeju Naval Base is built for both warships and civilian ships--such as cruise ships--to use. Just like the United States' Pearl Harbor, Jeju Naval Base will become not only the largest military base, but a beautiful tourist site.

While the United States and other Western states are in trouble with COVID-19 crisis, China is continuing its aggressive ocean expansion with its Gray-zone strategy. The Gray-zone strategy, which China uses around the South China Sea, refers to a strategy that promotes a change in international politics by creating an unclear state, neither war or peace. China, which is trying to expand its influence across East Asia, will also try to project a Gray zone strategy on the Korean Peninsula. The possible scenarios are as follows: 1) South Korea is accidentally involved in a dispute in the South China Sea, 2) Military conflicts between South Korea and China is caused by illegal fishing of Chinese boats in Yellow Sea, 3) China tries to interfere with Socotra Rock, 4) Unlikely, but possible in the future that China induce the military conflicts between Korea and Japan on the Dokdo issue. In order to cope with these scenarios, Korea should prepare the following measures from a long-term perspective: the creation of an Asian maritime safety fleet, the integ rated operation of the navy and the coast guard in the framework of the national fleet, and strengthening the conflict control system for China's provocations.

중국의 남중국해의 분쟁 도서 및 이에 속하는 배타적 경제수역과 대륙사면에 대한 주권과 '역사적 권리' 주장이 동아시아를 격변의 시기로 몰고 있다. 지난 수 십 년간의 중국의 놀라운 경제성장은 100년의 굴욕을 벗어나 '세계 강대국 복귀'라는 중국의 자부심 제고에 크게 기여했다. 그러나, 중국 정부는 지속적인 경제성장과 사회적 만족 유지에 필요한 자원 부족이 잃어버린 중국의 영광을 되찾는데 심각한 위협이 될 수 있음을 염려하고 있으며, 외국자원에 대한 의존성 증가를 그들의 사회적이며 경제적 안정과 자원안보의 심각한 도전으로 인식하고 있다. 2010년 이후 중국은 수차례에 걸쳐 남중국해를 중국의 "핵심 가치"라고 주장하고 있으며, 자원 부족이 중국에게 강압적 남중국해 전략 추진을 강요하고 있다. 본 논문은 자원부족이 중국에게 강압적인 남중국해 전략을 추진하도록 종용하고 있는 전략 환경에 끼친 영향을 분석해 보았으며, 또한 중국정부가 염려하고 있는 중국의 안정에 미치는 영향을 살펴보았다. 그리고, 중국의 자원부족과 이에 따른 강압정책이 중국, 동아시아 및 국제 사회에 미친 전략적 영향을 고찰해 보았다.

The Roman thinker, Cicero said, "The Nations that rule the sea, rule the world". In the world history, the countries done critical roles, have emphasized the importance of the sea. The world history is called as the histories of the countries which governed the sea, such as Phoenicia, Greece, Carthago, Roma, Portugal, Spain, England, and USA. The sea is not only the political, economical, social and cultural basis, serving as the origin of resources and channel of communication, logistics and distribution but also the area of dreams and imaginations and ground of potentiality and visions. This paper reviewed the major countries and their histories to realize the vision of Korea, super power country of maritime and fishery. Main maritime policies and its core issues and prospects of Korea were reviewed. And on the basis of these reviews, the vision of super power country of maritime and fishery was suggested. The vision, the 5th super power country of maritime and fishery in 2020, and 10th country of maritime technology level in 2020 and their details were proposed also. For achieving the vision, the resurrection of MOMAF is necessary and its reasons and 5 necessities were suggested. And the directions of the resurrection of MOMAF were proposed in terms of two viewpoints, policy/functional and institutional basis. I think Korea, the super power country of maritime and fishery, can be realized only when MOMAF may be resurrected.

Why did Kim Jong Un turn his foreign policy upside down in a sudden? US naval blockade became one of candidates for the reason since it had been threatened by Trump administration for the first time in December 2017. Has the blockades worked well like that in the international politic history? This paper reveals the effectiveness of naval blockade on sanctioning in the peacetime. This research analyzes three hypothetical arguments about the naval blockade based on the result of empirical tests with TIES Dataset. First, sanctions by blockading are more effective in gaining political benefits than the other economic sanctions. It was ranked the 4th effective way of sanction out of 9. And 56.3% of pacific naval blockades without packaged economic sanctions were succeeded, whereas the possibility of success increase up to 61.2% when blockade has been imposed in accordance with the other type of economic sanctions. Second, blockades deter military collisions, even war. When it comes to military provocation issue, blockading sanctions gain political interest far more than the other type of economic sanctions. The possibility of the success reaches up to 74%. Also, there wasn't any historical cases of war incurred by blockading sanctions within 5 years after the blockade end. Third, policy makers just need 1.2 years on average to see the end of sanctions when they choose the naval blockade as the method of imposing sanction on the adversary. It is impressively short span of time in achieving political goal compared to the other types of sanctions which are need 9 years on average. North East Asia sea could be the next stage for a naval blockade sooner or later. Because China and Japan not only possess capabilities of blockade but also have will to impose blockades to the others if conditions are set. And even the North Korea with lots of submerging forces could be a blockading threat in the specific area. So, the Republic of Korea has to pay more attention and be prepared for naval blockading sanction.

Maintaining sea superiority through successful mission accomplishments of warships is being proved to be an important factor of winning a war, as in the Ukraine-Russia war. in order to ensure the ability of a warship to perform its duties, the survivability of the warship must be strengthened. In particular, among the survivability factors, vulnerability is closely related to a damage assessment, and these vulnerability data are used as basic data to measure the mission capability. The warship's mission capability is usually measured using a wargame model, but only the operational effects of a macroscopic view are measured with a theater level resolution. In order to analyze the effectiveness and efficiency of a weapon system in the context of advanced weapon systems and equipments, a warship's mission capability must be measured at the engagement level resolution. To this end, not the relationship between the displacement tonnage and the weight of warheads applied in the theater level model, but an engagement level resolution vulnerability assessment method that can specify physical and functional damage at the hit position should be applied. This study proposes a method of measuring a warship's mission capability by applying the warship vulnerability assessment method to the naval engagement level analysis model. The result can be used as basic data in developing engagement algorithms for effective and efficient operation tactics to be implemented from a single unit weapon system to multiple warships.
