In Korea, all investigations of maritime crime such as murder, robbery, drug trafficking, and illegal fishing that have been committed at sea are under the jurisdiction of maritime police. As maritime crimes tend to have more unique cases, cause damage on a larger scale, and be limited to evidence that is possibly contaminated, compared to non-maritime crimes, the cases demand maritime police investigators with a higher level of expertise. However, there is currently a lack of competent investigators in the maritime police, leading to the training of maritime police investigators in training agencies. so many of maritime investigators goes to land police training agency including Korean Police Investigation Academy. Therefore, in order to improve the capabilities of maritime crime investigation we must first gather information and data in relation to maritime crimes to foster more investigation specialists, and establish specialized training agencies offering a training course more focused on maritime crimes.

Recent marine territorial disputes in the East China Sea and the South China Sea have come to us as a great threat. China, which has recently established the China Coast Guard and has rapidly developed maritime security forces, is trying to overcome the various conflict countries with its power. Japan is also strengthening intensively its maritime security forces. Since Korea, China, and Japan are geographically neighboring and sharing maritime space in Northeast Asia, there is no conflict between maritime jurisdiction and territorial rights among the countries. The struggle for initiative in the ocean is fierce among the three coastal nations in Northeast Asia. therefore, Korea needs more thorough preparation and response to protect the marine sovereignty. As the superpowers of China and Japan are confronted and the United States is involved in the balance of power in strategic purposes, the East Asian sea area is a place where tension and conflict environment exist. China's illegal fishing boats are constantly invading our waters, and they even threaten the lives of our police officers. The issue of delimiting maritime boundaries between Korea and China has yet to be solved, and is underway in both countries, and there is a possibility that the exploration activities of the continental shelf resources may collide as the agreement on the continental shelf will expire between Korea and Japan. On the other hand, conflicts in the maritime jurisdictions of the three countries in Korea, China and Japan are leading to the enhancement of maritime security forces to secure deterrence rather than military confrontation. In the situation where the unresolved sovereignty and jurisdiction conflicts of Korea, China and Japan continue, and the competition for the strengthening of the maritime powers of China and Japan becomes fierce, there is a urgent need for stabilization and enhancement of the maritime forces in our country. It is necessary to establish a new long-term strategy for enhancing the maritime security force and to carry out it. It is expected that the Korean Coast Guard, which once said that it was a model for the establishment of China's Coast Guard as a powerful force for the enforcement of the maritime law, firmly establishes itself as a key force to protect our oceans with the Navy and keeps our maritime sovereignty firmly.

South Korean national security strategy should be developed to effectively handle and counter increasing maritime threats and challenges. There are three major maritime threats South Korea faces today; maritime disputes on the EEZ boundary and Dokdo islet issues, North Korean threats, and international maritime security. Maritime disputes in the region are getting intensified and turned into a military confrontation after 2010. Now regional countries confront each other with military and police forces and use economic leverage to coerce the others. They are very eager to create advantageous de facto situations to legitimize their territorial claims. North Korean threat is also increasing in the sea as we witnessed in the Cheonan incident and Yeonpyoung shelling in 2010. North Korea resorts to local provocations and nuclear threats to coerce South Korea in which it may enjoy asymmetric advantages. The NLL area of the west sea would be a main hot spot that North Korea may continue to make a local provocation. Also, South Korean national economy is heavily dependent upon foreign trade and national strategic resources such as oil are all imported. Without an assurance on the safety of sea routes, these economic activities cannot be maintained and expanded. This paper argues that South Korea should make national maritime strategy and enhance the strength of naval forces. As a middle power, its national security strategy needs to consider all the threats and challenges not only from North Korea but also to maritime security. This is not a matter of choice but a mandate for national survival and prosperity. This paper discusses the importance of maritime security, changing characteristics of maritime threats and challenges, regional maritime disputes and its threat to South Korea's security, and South Korea's future security strategy and ways to enhance the role of naval forces. Our national maritime strategy needs to show middle and long term policy directions on how we will protect our maritime interests. Especially, it is important to build proper naval might to carry out all the roles and missions required to the military.

The paper evaluated the effects of port hinterlands and suggested the policies to improve them in Korea. The results of evaluation indicated that it is difficult for the effects to be evaluated so good. It seems that a lot of efforts should be made to make port hinterlands carry out their own functions well, in that, in particular, they have had so bad effects in carrying out such functions as production, international trade, and city. Policy actions were suggested including reduction of rent, strengthening international logistics networks, and governmental funding etc.

This study analyzed a correlation between South China Sea summer (June to September) monsoon (SCSSM) and the ENSO for the last 32 years (1979 to 2010). There was a correlation that the higher (lower) the SST in the $Ni{\tilde{n}}o-3.4$ region was, the weaker (stronger) the SCSSM intensity was. To identify the reason for this correlation, a difference of means between 8 El $Ni{\tilde{n}}o$ years and 8 La $Ni{\tilde{n}}a$ years (June to September). The analysis on the difference between two groups with respect to the 850 hPa stream flows showed that there were anomalous huge cyclones in the subtropical Pacific in the both hemispheres so that cold and dry anomalous northerlies were strengthened in the South China Sea relatively while anomalous westerlies were strengthened from the Maritime Continent to the off the coast of Chile. The analysis on the difference between two groups with respect to the 200 hPa stream flows showed that the opposite anomalous pressure system pattern to that in the 850 hPa stream flows were shown. In the subtropical Pacific of the both hemispheres, anomalous anticyclones existed so that anomalous easterlies were strengthened from the Maritime Continent to the equatorial central Pacific. Considering the anomalous atmospheric circulations in the upper and lower layers of the troposphere, upward airflows from the equatorial central and eastern Pacific were downward in the South China Sea and the Maritime Continent, which was a structure of anomalous atmospheric circulations. This means that the Walker Circulation was weakened and it was a typical structure of atmospheric circulations revealed in El $Ni{\tilde{n}}o$ years.

The stability, reliability and efficiency of a smart ship are important issues as the interest in an autonomous ship has recently been high. An automatic collision avoidance system is an essential function of an autonomous ship. This system detects the possibility of collision and automatically takes avoidance actions in consideration of economy and safety. In order to construct an automatic collision avoidance system using reinforcement learning, in this work, the sequential decision problem of ship collision is mathematically formulated through a Markov Decision Process (MDP). A reinforcement learning environment is constructed based on the ship maneuvering equations, and then the three key components (state, action, and reward) of MDP are defined. The state uses parameters of the relationship between own-ship and target-ship, the action is the vertical distance away from the target course, and the reward is defined as a function considering safety and economics. In order to solve the sequential decision problem, the Deep Deterministic Policy Gradient (DDPG) algorithm which can express continuous action space and search an optimal action policy is utilized. The collision avoidance system is then tested assuming the $90^{\circ}$intersection encounter situation and yields a satisfactory result.

This study is aimed at finding policy directions for Korean fisheries and fishing villages by using Delphi method for fisheries experts. Fisheries experts have highly evaluated the achievements of fostering aquaculture industry, seafood export support measures, and natural disasters relief and recovery arrangements among the policies promoted as so far. And it was recognized that policies such as fishery resources management, creation and recovery of fishery resources, improvement hygiene and seafood safety, and provision young fishermen with training and capacity building will be important. Future megatrends, for example changes in food consumption pattern, climate change, and demographic structure changes are expected to have a significant impact on fisheries and fishing villages. The Delphi survey indicates that the most important policy objective is to secure a stable fisheries production. In other words, fisheries policy in the future should be aimed at suppling sustainable seafood for popular consumption. Finding strategies and action plans that can achieve this goal will be an important policy issue. In conclusion, it is necessary that a number of fundamental researches carry out in Korea, which can lead to finding out a multifunctionality of fisheries and fishing village. In addition, it is important to expand the scope of fisheries policy, which can consider not only the fisheries producers but also seafood consumer's and young fishermen perspectives. Furthermore, it recommends that fishery policy needs to include fishery related industry as well as application of 4th industrial revolution technology to fishery.

Between 1920 and 1996, a total of 39 Conventions, 29 Recommendations and one Protocol were adopted by the International Labour conference. But Many ILO Instruments were outdated, deficient and not reflective of modern practice, many contained technical detail which discouraged ratification and were thus ineffective. However, many issues which had become relevant were not covered by existing instruments. Therefore, the Governing Body of ILO, at its 262nd Session(March-April 1995), decided to set up a Working Party on Policy regarding the Revision of Standards. It was decided that the Working Party would examine the need for revision of all maritime Conventions and Recommendations adopted before 1985 with a view to rejuvenating and strengthening the standard-setting system. The Working Party initiated its examination of maritime instruments during 273rd Session(November 1998) of the Governing Body. The review made by the Working Party has concluded that of the maritime Conventions examined, seven of them are obsolete and should be revised, 13 should be denounced and six were considered either up to date or were identified for promotion, most of which were approved by the Governing Body. The consolidated maritime labour convention will be adopted in February 2006.

Republic of Korea is the first country which received international aids, h1s become a member of DAC, and recently has strengthened the international aids policy through ODA(Official Development Assistance). Korea ODA has focused on the area of education, social infrastructure, etc., but not on maritime affairs. However, since Korea has become a maritime country and a member of "A Group" council of IMO, the international shipping community including IMO strongly requests Korea to transfer Korea's maritime safety technology to developing countries for the sake of international maritime safety and marine environment protection. In this study, the direction of road map for effective transfer of maritime safety technology and marine environment protection technology was presented. The strategy for implementation of the suggested road map was proposed as well.

IMO is treating various and numerous agenda with time, and the contents of agenda have been tending to achieve international standardization for details of technology, for example GBS(Goal based new ship construction standards), PSPC(Performance Standards of Protective Coating), LRIT(Long-Range Identification and Tracking of Ships), etc. This paper presents the latest agenda trend of IMO committees and analyzes the ROK's activities in response to IMO committees. In the result of analysis, ROK lacks in performance ability as a A-category council member as well as infrastructure to support the government activities in IMO continuously. Therefore, ROK should be conscious of policy approaches to international maritime tendency and needs to complete the internal/external infrastructure which leads the international maritime policy.
