AIS is the most important navigation equipment for the identification of other ships, etc. However, the AIS overload problem has been raised recently due to an increase in AIS equipped vessels. The government is planning to introduce the wireless LTE network at 100 km offshore as part of the SMART-Navigation project. Continuous development and dissemination of the services available through such platforms will be necessary to achieve major goals such as marine accident prevention and environmental protection. In this study, we applied a WAVE communication system, which could be the basis for the development of such services. As a result, reliable data transmission was confirmed for a range of communication of approx. 5 miles, although the service was limited to 1 km in road traffic. Therefore, it is expected that WAVE communication technology will be used to prevent marine accidents through such efforts as collision avoidance and the transfer of marine safety information between ships.

This paper attempts to quantitatively assess the conservation value of Ellobium chinense (EC), which belongs to the endangered marine species designated by Ministry of Oceans and Fisheries. To this end, we apply the contingent valuation (CV) method, an economic technique of valuing a non-market goods such as EC. A national survey of randomly selected 1,000 households was administered in order to derive the public's willingness to pay (WTP) for conserving EC. One-and-one-half-bound model was adopted to elicit the WTP responses and a spike model was employed to deal with the zero WTP responses. The results show that the conservation value of EC is estimated to be 2,346 won per household per year that is statistically significant at the 1% level. Expanding the value to the national population gives us an annual value of 43.8 billion won. We can judge that the Korean people are willing to pay a significant amount to conserve EC.

한국은 세계 유일의 분단국가로서 대륙으로는 북한과 대치 중에 있으며, 해양으로는 세계 강대국인 중국, 일본, 러시아 등에 의해서 둘러 쌓여 있다. 이러한 안보환경에서 최근 북한은 김정은 후계세습을 위해 천안함 피격사건과 연평도 포격도발 사건을 감행하였으며, 이러한 북한의 도발위협은 김정일 사후 지속되고 있다. 그러나 한국은 북한이라는 현존 위협에 대비함과 동시에 주변국으로 상정할 수 있는 잠재적 위협에도 대비해야 한다. 특히 잠재적 위협의 경우 해상에서 한국과 국가이익이 상충되고 있으며, 이들 모두 한국보다 강한 해군력을 보유하고 있을 뿐만 아니라 최근 들어 해군력을 강화하고 있다. 따라서 최근의 안보정세는 한국해군이 향후 어떠한 해양전략을 추구해야 하는지에 대한 재정립을 요구하고 있다고 할 수 있다. 본 논문은 한국의 잠재적 위협인 러시아와 일본 간에 발생한 러일전쟁을 통해 미래 위협에 대비한 최정예해군(Post modern navy)으로 도약하기 위한 한국해군의 발전방향을 도출하고, 이를 달성하기 위한 4가지 핵심개념을 제시하였다. 구체적으로 이는 최정예해군으로서 해양통제와 거부를 균형적으로 갖추고, 원정작전 수행능력을 보유하며, 해양경찰과 결속력이 있는 유대관계를 형성 및 북한의 비대칭전력에 대한 대응능력을 갖춘 해군이라고 설명할 수 있다. 결국 한국해군은 대륙세력인 북한의 위협에 대비하고 동시에 미래 잠재적 위협에 대비함과 동시에 해양에서의 국가이익을 보호해야 한다고 할 수 있다. 한국은 해양국가이다. 한국은 결코 바다를 포기할 수 없으며, 한국해군이 추구하는 해양전략은 국가의 운명을 결정짓는다고 해도 과언이 아닐 것이다. 이러한 측면에서 본 논문은 향후 한국해군이 어떠한 해양전략을 추구해야 하는지에 대해 하나의 방향을 제시하고 있다.

The IMO e-navigation strategy has requested a communication infrastructure providing authorized seamless information transfer between stakeholders. The Maritime Cloud is the term used to describe the concept of an infrastructure that support authorized, seamless information transfer, adding those elements, that are necessary to support the e-navigation domain. It is necessary to consider the study on maritime cloud security, but the study is still an early stage. In this paper, we propose a secure synchronization method for the maritime cloud services. The proposed method can be synchronize between the vessel based on the SH-Tree, and it has the advantage that there is no exposure information in the synchronization process.

In this paper, we study a FDS(fishery detection system) for protection of an aquaculture farm. The FDS will identify a robbing vessel with real time and detect variance of the position of aquaculture farm. We also propose a F-AIS(Fishery- Automatic Identification System), which can detect the object approaching to aquaculture farm and distinguish fishing boats from thief vessel The F-AIS with low price and wideband responsibility will be adopted to the FDS.

This paper describes Fishery Safety and Security System using F-AIS based on the concepts of RFID(Radio Frequency Identification). This system is to track, protect and arrest the thief who invaded in an fishing ground. The system composed with various functional modules to implement selectively available system providing low cost to high cost and simple function to high function according to user's requirement in a practical fishing fields. Sea trial tests are carried out at Mokpo, Busan and Incheon and, it is found that the system can guard the wide area of cultivating farm field.

This paper describes the implementation procedures and results of Fishery Safety and Security System to secure an aquaculture area from a thief. The system designed with various functional modules to implement selectively available system providing low cost to high cost and simple function to high function according to user's requirement in a practical fishing fields. In the abalone farm field located in Jin island, Jeonranam province and having condensed aquaculture facilities with 50 cages (10 row by 5 column) within 0.5 miles from coast, practical field tests are carried out. As results from that tests, it is found that the system can guard not only the whole area of cultivating farm field but also each cages with detail.

Bans on TBT based antifouling paints have been drafted since 1998 by meetings 42, 43, 45 and 46 for the MEPC (Marine Environmental Protection Committee) of the International Marine Organization, and decided finally at a Diplomatic Conference of IMO in October 2001. It was a key issue that there should be a global prohibition on the application of organo-tin compounds as biocides in Anti-fouling systems by Jan. 2003, and a complete prohibition on the presence of organo-tin compounds on ships by 1 Jan. 2008. This paper suggests a method to design International Anti-fouling system cretificate, Record of anti-fouling system, Endorsement of the Records, Declaration on Anti-fouling System, Port State Control and reform(legislative) associated a law.

There is a growing concern about the damage to aquatic ecosystem caused by immigration of non-indigenous species. It is estimated that more than 10,000 million tons of ballast water is transported by shipping activities annually, and ballast water has been recognised as a major vector for the transplant of aquatic species across bio-geographical boundaries. The problem of harmful aquatic organism in ballast water for the control and management of ships' ballast water and sediments was adopted and diplomatic conference of IMO at February 2004. At once ballast water is transported by shipping activities for organic compounds, nitrogen, phosphorus and heavy metal etc. but, It's fixing a focus only for the transported of pathogenic bacteria and non-indigenous species. Hence, this studies on the distribution of organic compounds, nitrogen, phosphorus and heavy metal in ballast water during the shipping activity with the basic data which is necessary to the systemic manage of ballast water.

This study collected data of college students' volunteering for maritime and fisheries and found that only few subjects participated in it. They took part in control for release of oil, services for sea village and coastal cleansing. Most were satisfied with their volunteering referring contributing to environment protection, self-fulfillment, social interaction, gaining special experiences and assimilation with nature. The subjects were not satisfied with lack of systematic and effective services, monolithic activities, insufficient publicity, deficient rewards and a shortage of self-capacity. Based upon the research findings, implications for college students' volunteering policies were suggested to promote volunteering for maritime and fisheries.
