This thesis analyzes Somali piracy as a non-traditional threat to the Sea Lines of Communication (SLOC) and international countermeasures to the piracy. In an era of globally interdependent economies, the protection of sea lines and freedom of navigation are prerequisites for the development of states. Since the post-Cold War began in the early 1990s, ocean piracy has emerged as a significant threat to international trade. For instance, in the Malacca Strait which carries 30 percent of the world's trade volume, losses from failed shipping, insurance, plus other subsequent damages were enormous. Until the mid-2000s, navies and coast guards from Malaysia, Indonesia, Singapore, together with the International Maritime Organization (IMO), conducted anti-piracy operations in the Strait of Malacca. The combined efforts of these three maritime states, through information sharing and with reinforced assets including warships and patrol aircrafts, have successfully made a dent to lower incidents of piracy. Likewise, the United Nations' authorization of multinational forces to operate in Somali waters has pushed interdiction efforts including patrol and escort flotilla support. This along with self-reinforced security measures has successfully helped lower piracy from 75 incidents in 2012 to 15 in 2013. As illustrated, Somali piracy is a direct security threat to the international community and the SLOC which calls for global peacekeeping as a countermeasure. Reconstructing the economy and society to support public safety and stability should be the priority solution. Emphasis should be placed on restoring public peace and jurisdiction for control of piracy as a primary countermeasure.

Participation of ROK navy in the Rim of the Pacific(RIMPAC) in likely to stimulate rethinking of Korea's defense role in Northeast Asia. Although the RIMPAC exercise was originally maneuvers to improve combat techniques in ASW, anti-aircraft combat. ocean supply support. surface combat. and electronics warfare. it will be finally be directed to ward securing the SLOC connecting the US, Canada. Australia and the Far East. Based on this concept, my conclusion is that two future arrangements are possible for the security of the Korean peninsula and protecting the SLOC in the combined defense of the Pacific. One is the naval cooperation between ROK and Japan. the other is the Standing Naval Force Pacific(STANAVFORPAC) The concepts of the Naval Cooperation between ROK and Japan and the STANAVFORPAC is whose time has come. The leaders, policymakers, and planners of the countries concerned need to consider such a move seriously.

The Chinese government portrays the One Belt One Road Initiative (BRI) and South Korea President Park Geun-hae's Eurasia Initiative as a win-win opportunity which will hurt nobody's interests, but some South Korean commentators have interpreted it as much more than just a trade and development deal: they focus on the geopolitical implications and the possibility that the balance of power in Asia will be disturbed. South Korea depends upon its maritime-oriented Sea Lanes of Communication (SLOC) in focusing on its alliance with the US to deter North Korean threats and explore its export-based economic growth and development, and yet cannot afford to be left out of these initiatives which could transform the economic and logistical linkage between South Korea and Europe. Given its negative reception by the some pundits, however, South Korea should be more precautious for expressing only full-fledged supports for the BRI and Eurasia Initiative. Opponents of these two initiatives doubt that its putative benefits can be realized, at least in the short term, arguing that creating the necessary rail interconnections may be too costly.

It is a commons sense that the Republic of Korea is a maritime state that depends its survival on International Trade and International Economy. Korea was a peninsula and do it can be both maritime and continental state by its choice. However, after the national division in 1945, South Korea had became a virtual island and pursue a maritime way for national development in the past 60 plus years. Now, South Korea is becoming a world's 12 th largest major trading and maritime state. South Korea has far more ships per capita than any other nations in the world and its economy is heavily depend upon the imports and exports with other nations in the world that pass through the oceans. Therefore, the Koreans regard the security of the sea lanes of communication as vital to the survival of the nation. The SLOC is the life line for Republic of Korea. Since the early 1990s, immediately after the Cold War was over, South Koreans began to recognize the importance of Sea Routes and thus began to build a navy that can handle with the new problems of the post Cold War era. However, the maritime security environments of the Republic of Korea today is shaky and dangerous. Almost every water near the Korean peninsula, some kind of international confrontations are going on. Territorial disputes on Dok do, Senkaku, Scarbrough, Shisha, Nansha and Eodo between and among Korea, Japan, China, Taiwan, Phillipines, Indonesia and Vietnam are the examples. In this essay, the author argues that the S. Korean efforts and capabilities to deal with these challenges are not enough and exhorts more efforts and more powerful navy for the Korean people.

The purpose of this paper is to analyze the status of naval arms race in Northeast Asia. To this end, the scope of the research was limited to national security strategies, maritime strategies and naval strengthening of the United States, China, Russia and Japan. The major powers' active maritime strategies and naval arms race give some strategic implications to the Republic of Korea Navy as follows. First, China and Japan, unlike the past, are actively using submarines in offshore waters including the Korean Peninsula. Therefore, the ROK Navy must successfully promote the Jangbogo-III-class submarine, which is currently constructed, and get a nuclear-powered submarine and P-8 MPA capable of long-range and long-time operations to enhance ASW capability. Second, North Korea's current building submarines capable of loading SLBMs and SLBMs are a new threat to the ROK Navy. The current building KAMD, which focuses on terminal phase defense, cannot effectively respond to North Korea's SLBMs and should be converted to a multi-layered defense system including SM-3 at a mid-course phase. Third, as China militarizes the South China Sea, the instability of the South China Sea is growing. Therefore, the ROK Navy should strengthen its maritime cooperation with the regional countries such as Japan and ASEAN navies to protect SLOC. In conclusion, the ROK Navy needs to build a strong naval power to keep in mind that the 21st century naval rivalry in Northeast Asia is accelerating. The navy must do one's best to protect national strategic and vital interests by strengthening cooperation with regional countries. South Korea is also accelerating its defense reforms in accordance with the pattern of future warfare and the ROK Navy do one's best to have a balanced naval capability capable of actively operating in the offshore waters.

Today distant oceans around the world are regarded as a major 'global commons' for international trade and transportation. Korea is not an exception, because Korea hugely depends on sea lines of communication (SLOC) for supplying vital commodities such as food and energy resource. As a result, assuring a free and safe use of distant ocean beyond territory is also an important agenda for Korea's maritime security. However there are a number of challenges for Korea to enjoy a free and safe use of distant ocean; dangers of regional maritime conflict in East Asia, naval arms race of China and Japan, and concerns on possible decline of U.S naval presence and power projection capabilities. These factors provide a reasonable basis for Republic of Korea Navy (ROKN) to pursue capabilities for major naval operations at distant ocean in a long-term perspective toward the year 2030. The introduction of aircraft carrier and nuclear-powered submarine is a key requirement for achieving this goal. ROKN needs to acquire a 'multi-role strategic landing platform' type of light aircraft carrier, which takes a role to escort naval task force by providing air superiority at distant ocean. Additionally nuclear-powered submarine will offer ROKN a formidable power to carry out offensive missions effectively at distant ocean.

Revolution of Shale gas literally brings about great changes in many spheres. In the past most academic research had been focused on the influence and innovative change in term of economic perspective. But nowadays we should more concern about the security approach and perspective as its status of the future's core energy resources. Revolution of Shale gas has an great influence on the reshaping of global and regional alliance order. There are many international political implications as follows. Contribution of energy hegemony with leading U.S.; Acting as strategic leverage on the reshaping international order; Deepening competition among major states on the construction of energy security and so on. We'd better make a good solution and systematic policies which are preparing for the Shale gas's revolution period including on the understanding about the change on the global energy structure and making a national policy agenda of energy security issues and so on. The thesis like 'to get the energy resources is to get the hegemonic power in the world' will persist. The same holds good of Shale gas case. To meet the revolution of shale gas era, we have important tasks as like making an opportunity to develope not only regional but also international prosperity.
