In relation with inspection systems of small fishing vessels, Government is drawing up revision of the law about ships safety act(Article 3) on the basis of supporting safe fishing activities to expand the application range of ships safety act for vessels under 2 tons(small fishing vessels) that are exempted from inspection systems. There are two opinions about inspection of small fishing vessels. Government's opinion is that inspection of small fishing vessels must be enforced to confirm small fishing vessels' safety but fishermen's opinion is that inspection systems keep on existing law because inspection systems spends a lot of time and money to the poor and the old. The alternatives for countered opinions is that the poor fishermen's vessels' for living or small vessels' inspection must be operated by themselves in principle and minimizing the limitation through policies is recommended. In addition, Government needs to develop various programs for inspection systems of small fishing vessels like the main fisheries countries. Particularly, in case of operating inspection systems of small fishing vessels, Government needs to consider some solutions for example supporting inspection fee, minimum inspection for confirming vessels' safety, inspecting when a vessel is building, expanding an inspection period.

Aids to Navigation (AtoN) are marine traffic facilities to improve the safety and efficiency of shipping. "New Dangers" should be appropriately marked using lateral, cardinal or isolated danger marks or by using an Emergency Wreck Marking Buoy. However, Emergency Wreck Marking Buoys are difficult to implement in terms of speed and accuracy of installation. In the case of sinking accidents, it is often difficult to immediately install an Emergency Wreck Marking Buoy because of weather conditions, the marine environment or accident positioning. This study concerns Auto-Releasing Emergency Wreck Marking Buoys, which should be installed in all vessel for safe marine navigation and efficient maritime transport with reference to the Maritime Buoyage System (MBS). Auto-Releasing Emergency Wreck Marking Buoys include an auto-release unit, auto reel chain and auto lighting lantern. These buoys can be automatically released from the deck of a vessel and will float in the water for quick installation at the scene of an accident, even in the case of sinking accidents. Auto-Releasing New Mark Buoys are expected to reduce to installation process, prevent secondary accidents by the risk of navigation and be search and rescue rapidly.

This study investigated the environmental conditions and planktonic organisms in the ballast waters (BW) of 22 vessels originating from the international ports of Japan for the purpose of negotiating exemptions from the Ballast Water Management Convention (BWM Convention). The shortest duration of the BW was $3.33{\pm}1.87days$ in area "A", which included Kyushu and Suo Nada at Seto Inland. The total suspended solids, dissolved organic carbon, and particulate organic carbon ranged from 4.60 to 60.9 mg L-1, from 0.97 to 2.69 mg L-1, and from 0.24 to 4.51 mg L-1, respectively. A low average concentration of nutrients was measured in the BW from area "A", but that in the BW from area "C" (around central Honshu) was high, which may be related to the ballasting periods. High chlorophyll-a concentrations (>$1{\mu}g\;L-1$) were measured in four vessels, three of which carried the BW in area "A". High abundances of phytoplankton (> 50,000 cells L-1) were measured in four vessels, three of which carried the BW in area "A". The two vessels originating from Tokyuyama Bay in area "A" showed high densities of dinoflagellates, which are known to be harmful algae. Our results suggest that the negotiations for an exemption from the BWM Convention for Japan should proceed with caution.

In the last 5 years, a total of 567 accidents of operating vessels occurred under the influence of alcohol at sea, most of which occurred in fishing boats. Accidents caused by operating vessels under the influence of alcohol at sea are causing human and physical damages. There were 69 accidents caused by operating vessels under the influence of alcohol, leading to five deaths and one missing. The social damage due to operating vessels under the influence of alcohol is also increasing. Under the current law, punishment is given lightly compared to the seriousness of violation. In order to prevent the recurrence of accidents caused by operating vessels under the influence of alcohol, cases in Korea need to be analyzed. Regulations on the crackdown in foreign countries were compared to those in Korea and reviewed. In addition, risks of operating vessels under the influence of alcohol should be provided to ship workers while improving related laws and systems. In addition, efforts should be made to reduce the number of accidents due to operating vessels under the influence of alcohol by strengthening crackdowns on ships at sea so that accidents caused by operating vessels under the influence of alcohol could be prevented in advance in the future.

최근 해상교통관제시스템(VTS : Vessel Traffic Service)은 항행지원정보교류가 가능한 육상국으로서 선박 통항의 안전과 효율성을 증진시키고 환경을 보호하는 e-Navigation의 핵심적 시스템으로 역할이 기대되고 있다. 최근 IALA를 통하여 국제적으로 데이터 공유를 위한 구조에 대한 연구와 표준 포맷이 정해지고 있으며 IVEF(IVEF:Inter-VTS Data Exchange Format)는 이중의 한 중요한 요소이다. 이러한 실시간의 트래픽 정보는 국가적으로 보안에 민감한 요소이나 현 규격에 정해진 보안성에 대한 규정은 다소 정해진 바 없이, 연동하기 위한 보안 규격을 다시 설계하여 상호 추진하고 연동시험을 수행해야 될 수준이다. 또한 Radar에 대한 물표 자체의 전달은 현재 고려하고 있지 않기 때문에 Track되지 않은 물표는 불필요한 많은 속성들을 같이 전송해야 하며, 레이더 물표에 대한 별도의 정해진 속성은 없는 상태여서 기존의 선박의 길이를 기반으로 비율을 고려하여 다시 재 산출되어야 가능하다. 따라서, 본 연구에서는 이러한 데이터 공유를 위한 IVEF의 규격을 검토하고 이를 보완하는 내용을 고려하여 새로운 프로토콜 및 방안을 제시한다. 이러한 구조는 VTS 시스템에서 적용 가능한 방안인지를 확인하여, 실제 적용할 수 있는 기술개발로서 방향을 정립하고자 한다.

Component-Based Development(CBD) for a system has benefits in terms of improvement of operation and maintenance as well as reduction of development period. But applying the CBD methodology to a system can give rise to difficulties, which are there should be specialists in CBD and domain to apply and there would be a lot of products resulting in the application. To solve the problems, we suggested a suitable methodology in overall process from analysis to implementation after investigating the methodology applicable to small and medium software system by software systems engineering approach. In the application of the suggested methodology to design a ship design process management system, we could confirm the efficiencies of the methodologies.

The right of hot pursuit is an exception to the general rule that a ship on the high seas is subject to the jurisdiction of the state whose flag she flies. The right of hot pursuit is provided in the United Nations Convention on the Law of the Sea. This paper discusses the requirements for the right of hot pursuit. The use of force should be avoided during hot pursuit. When force is unavoidable, it should not be used beyond what is reasomable and necessary in the circumstances.
