In this study, we sought to establish a vessel-discharge pollutant-treatment system recommended by IMO by first investigating advanced facilities overseas to help us understand and evaluate our domestic facility and needs. IMO recommends the installation and operation of port pollutant-storage facilities to adequately treat pollutants emitted by ships entering the port, and we reviewed the registration and operation of these facilities in IMO member countries, focusing on the IIII Code. Due to recent environmental regulations, additional facilities are required to treat the washing water discharged from equipment such as scrubbers mounted on the ship so pollutant-storage facilities must be established. Currently, Korea's ship-discharged wastes are being moved from ports to land waste-treatment plants, and their quantity and properties are not being monitored. Therefore, in this study, we improved monitoring of the discharged pollutants and investigated the proper arrangement of pollutant storage facilities as recommended by IMO. The system we established can help provide smooth service to incoming ships - and appropriate treatment of pollutants and will greatly benefit international maritime operations.

Recently, with the worldwide development of the fourth industry, the development of technologies for smart and eco-friendly ships is accelerating. With the emergence of autonomous vessels with complete unmanned or minimum personnel on board and eco-friendly fuel (methane, ammonia, electricity, etc.), the role of existing seafarers on board is expected to change significantly. To improve the competitiveness of seafarers in the future, predicting future seafarer occupation groups, improving the educational curriculum, and creating an educational system are necessary. In this study, eight occupational groups that seafarers may have in the future were derived through a review of earlier studies and brainstorming of maritime university students, incumbent seafarers and expert groups. A survey was conducted on the eight occupational groups using the Likert scale, and based on the results, a leading occupational group related to future seafarer was derived. The most likely occupational groups with high scores were remote control centre operators and cargo remote manager. In addition, essential educational elements to be educated first for these occupational groups were derived and presented.

The International Maritime Organization(IMO) which is responsible for measures to improve the safety and security of international shipping and to prevent marine pollution from ships is a specialized agency of the United Nations. It is involved in legal matters, including liability and compensation issues and the facilitation of international maritime traffic as well. But the ROK has not been actively coping with the environment of the shipping industry because of the absence of the organization or researching bodies that specialized in the field related to IMO. Therefore this paper investigates the maritime administration system of the major countries such as the USA, japan and the UK. And particularly by conducting IMO research and responding system, this study gathers relevant materials from those countries for the comparison and analysis with the purpose of providing the ROK with the assistance in forming the responding measures in the shipping and shipbuilding industries.

There have many research papers to see China's evolution of maritime strategy and naval modernization in terms of its naval mind-set. However, this article focuses on assessing how China uses its all sorts of maritime strength to achieve 'a building maritime great power.' The aim of the article is to introduce a new perspective to this debate by analysing China's diversified ma maritime capabilities and a new way of implementation in maritime security strategy. In recent years, China has been developing not only unpredictable maritime military capabilities but also maritime supporting forces - Coast Guard and Maritime Militia. And recently China adopted up-to-date operational concept aimed at gaining military superiority in Asia-Pacific waters. By taking salami slicing strategy, gray zone strategy and cabbage strategy, China has been trying to exercise surpassing influences in regional maritime area, also in western Pacific region. This article provides a stepping stone to comprehend the aspect of China's recent maritime strategic actions, especially in Yellow Sea. In conclusion, this article suggests some policy recommendations for countering China's coercive maritime strategy. First, Korea should make sure a strategic concept of maritime security, instead of land warfare focused strategic concept. Second, it is needed to set up suitable naval forces for actively responding to neighbor nation's offensive actions.

2010년 천리안위성의 성공적인 발사에 따라 인공위성의 활용에 대한 기대가 커지고 있다. 천리안 해양관측위성(GOCI)이외에 아리랑 2호가 현재 운용중인 우리나라 위성들이다. 가까운 시기에 아리랑 5호(2011년 말), 아리랑 3호(2012년), 아리랑 3A호(2013년)가 발사될 예정이다. 즉, 해양적용을 위한 위성환경은 이제부터 준비되고 있다고 볼 수 있다. 대외적으로 보면, 인공위성 자원은 아주 많다. 문제는 이와 같은 자원을 어떻게 활용할 것인가 인데 이의 활용 기술 개발적 측면에서는 많이 소홀한 것이 사실이다. 전세계적으로 이 시스템 개발을 위한 치열한 경쟁이 진행 중에 있다. 이미 소말리아 주변 감시체계는 많은 부분을 위성에 의지하고 있다. 우리나라에서 최초로 위성활용 가능성을 보여준 사건이 허베이스피리트호 원유유출 사고이다. 이 사고는 2007년 12월7일 아침 7시6분경 서해안 만리포 북서쪽 10km 해상에서 크레인을 적재한 1만1800t급 바지선이 정박 중인 홍콩 선적 유조선 허베이 스피리트호(14만6000t급)와 부딪치면서 발생했다. 이와 같은 기름 유출 사고의 경우, 유출 범위를 정확하게 이해하는 것이 중요하다. 거의 준비된 상태가 아님에도 불구하고 12월 8일 아침 최초로 유출된 기름을 모습을 보여주는 위성이미지(광학위성)가 얻어졌다. 하지만 이와 같은 자료가 관련 전문가가 이용할 수 있기까지 많은 시간이 소용되었고, 이 정보를 전달할 수 있는 방법도 없었다. 사실 단순한 이미지가 아니라 지리정보체계를 가진 오염정보를 제공할 방법도 준비도 되어 있지 못한 상황이었다. 본 발표를 통하여, 허베이스피리트호 사고뿐만 아니라, 2011년 6월부터 수개월간 지속된 발해만 오염사고 적용 등 다양한 사례 소개를 하고, 이를 기반으로 해양경찰청에서 업무활용을 위한 방안을 제시한다. 먼저, 해경청의 주요 임무인, 경비, 수색구조, 오염대응 분야별로 현황 분석을 수행하였다. 또한 국외사례에 대한 조사를 한 후, 최종 인공위성 원격탐사기술의 해경청 도입방안에 대한 설계를 실시하였다. 국제적으로 인공위성을 이용한 해양 경비, 수색구조, 오염 모니터링기술 개발이 이루어지고 있으며, 유럽 국가는 시범도입을 진행 중에 있다. 유럽해사안전국(EMSA)은 해양경비 및 수색구조를 위한 선박통항 및 보고 서비스와 오염대비대응(Pollution Preparedness and Response, PPR) 위성 서비스를 회원국에 제공하고 있다. 해양경찰청 임무 수행뿐만 아니라, 해양영토 관리적 측면에서 첨단 위성장비 활용, 선진국형 해상경비 패러다임의 전환 필요성이 크다고 할 수 있다.

Despite the facts that navigation technology and educational programs were developed, and that maritime law has been enforced strictly, the number of maritime accidents has not dropped significantly. Accident prevention is emphasized because of the extreme life, property, and environmental losses that accompany maritime accidents. Even though there are a variety of preventive activities, their performance is not satisfactory. In order to promote preventive activities and to organize safety management, a Preventive Index of Ship Accident(PISA) and a Preventive Level of Ship Accident(PLSA) which are abstracted from the statistical data of ship accidents (2009~2013) are proposed. The survey module by which these variables can be calculated is composed of preventive domains such as education, engineering, enforcement and information, and is applied for the preventive indexes measurement of cargo, passenger, tanker, tugboat and fishery ships. We compared and analyzed measured result with statistical accident rates and cases to confirm the index utilities. It was found that there is some correlation between the index value and the ship accident rate. It is expected that this index will become useful to evaluate a preventive status for the prevention of ship accidents and for the maritime safety culture.

The dispute between China and Japan regarding $Di\grave{a}oy\acute{u}t\acute{a}i$ is believed to be quite similar to the controversy surrounding Dokdo in terms of historical and post-war processes except for the point that the phenomena of occupation is different with regard to Dokdo. China's claim to $Di\grave{a}oy\acute{u}t\acute{a}i$ is based on historical title and continuous use while the basis of Japan's claim is summarized as preoccupancy of ownerless land. Even though Japan acknowledges that China discovered $Di\grave{a}oy\acute{u}t\acute{a}i$, Japan claims that the act to establish sovereignty over the island from the standpoint of International Law was not taken by China. However, at that time, effective occupation was not an essential prerequisite for the acquisition of a territory. That is to say, from a legal perspective, the legal right for an area could be established based on the discovery of the land, and so it is thought that Japan is applying the current criteria of International Law in a manner that is inappropriate. When we review the post-war process, the San Francisco Peace Treaty does not directly mention $Di\grave{a}oy\acute{u}t\acute{a}i$. But based on the said treaty, we can note that Japan gave up all rights for the southern area that is north of the boundary line that equates to latitude $29^{\circ}$ and that includes the Ryuku Islands and $Di\grave{a}oy\acute{u}t\acute{a}i$. Of course, the provisions for the territory in the San Francisco Peace Treaty and its disposal are not the final factor for the judgment regarding dominium of $Di\grave{a}oy\acute{u}t\acute{a}i$. However, it seems clear that Japan's attitude and interpretation regarding the issues of $Di\grave{a}oy\acute{u}t\acute{a}i$, the Kuril Islands and Dokdo is problematic.

The ocean in the 21st century is getting emphasized as a treasury of natural resources and a growth engine for the nation. And nations around the world have entered into the hyper-competition to take the initiative for those marine resources. Under the situation, the Korea Coast Guard is devoting itself with full force to protecting maritime sovereignty, ensuring maritime safety and security and preserving the marine environment. Purpose of this study is to analyze Maritime Policing Act of 2012 and their problems and to suggest improvement measures. Objectives of Maritime Policing Act of 2012 is national Defence, policing for maritime security, protection of marine natural resources and marine facility in territorial waters and exclusive economic zone(EEZ) of Korea. Limits of Maritime Policing Act of 2012 are as follows. First, As organization related rules in Maritime Policing Act of 2012 are not enough, Maritime police agency Act should be revised and enacted in order to cope with future administrative demands and legal ground. Second, Article 22 penal regulation is more severe than regulations of another Act. Third, Article 14 should be made improvement for pre-prevention through the pre-report and the establishment of prohibition boundary in maritime demonstration.

When oil tankers, large passenger ships and cargo ships sink under the sea owing to various maritime accidents, the residual cargo oil or fuel oil in the such vessels could pose direct risk to factor for the marine environment and it require safe and rapid removal. Although domestic and foreign salvage companies are adopting various recovery methods and technologies with customizations according to each site during recovery operations studies on reasonable assessment modules for the operation process are relatively insufficient. In this study, the data from trapped-oil recovery operations performed at different site conditions were collected and analyzed in order to designed an operation assessment module, define the operational process steps in terms of preparation, implementation and completion, and derive key factors for each detailed process. Subsequently, the module was designed in such a way as to construct performance indicators to assess these key factors. In order to exclude subjective opinions from the assessment as much as possible, the assessment each item was constructed with indicators based on data that could be evaluated quantitatively and its usefulness was verified by applying the module to the trapped-oil recovery operation cases. We expect this the method and the technology assessment module for the trapped-oil recovery operation on sunken vessels will help to verify the adequacy of the trapped-oil recovery such operation before or after. Furthermore, it is expected that the continuous accumulation of assessment data and feedback from past or future operation cases will contribute toward enhancing the overall safety, efficiency and field applicability of trapped-oil recovery operation.

Local management trade ports are small-sized trade ports, which require active operation to strengthen the local cities' economic power and enhance the local industries' added value. In addition, local management trade ports should berth ships larger than the existing ships to increase efficiency and keep up with the international trend where ships are becoming larger. Furthermore, they should also prepare operating standards. This study selected Okgye Port among local management trade ports. We performed a mooring safety simulation evaluation according to the scenario where a 50,000 DWT vessel is moored at the current 20,000 DWT class pier. The emergency departure criteria were 27kts at 3.2s of wave period and 22kts at 5.0s of wave period at the existing pier. Results showed that mooring limit condition increased by about 50% to 41kts at 3.2s of wave period and 36kts at 5.0s of wave period. This study can be used for strengthening mooring facilities and setting operational standards for safe port operation when large ships are berthing.
