General aspect of marine ranching programme in Korea was introduced. It contains the status of Korean fisheries industry, background and the scope of ranching project being conducted by KORDI since 1996. Long term plan for the marine ranching programme as a national project is also introduced including socio-economic analysis of project as well as economic impact of investment.

The Korean government has been carrying out the marine ranch development project since 1998 with the purpose of responding to the decrease in coastal fishery resources and fishery income, preparing a systematic management system for the sustainable use of fishery resources and realizing advanced fisheries power by expanding and upgrading fisheries resource development projects. In addition, the government established the Korea Fisheries Resources Agency and promoted projects for the protection and management of fishery resources by increasing basic productivity by artificially creating marine forests in areas where whitening events occur. Since the project of building marine ranches and marine forests requires immense government financial support, it is important to estimate the economic value and thoroughly evaluate the feasibility of the project. In this paper, the project of non-market economic value of the development of marine ranches and the development of marine forests was estimated. CVM (Contingent Valuation Method) was applied as a methodology for benefits estimation. Prior to the analysis, a one-on-one interview survey was conducted with participation of 512 residents and 514 residents respectively for the project of creating a marine ranch and developing a marine forest. A DBDC (Double-Bounded Dichotumous Choice) model was applied in the WTP (Willingness To Pay) analysis model and the socioeconomic variables of the surveyor, such as sex, age, education and income, were reflected in the model. The economic benefits from the two projects, namely, building of marine ranches and developing marine forests were estimated to be equal to 4,608 won and 7,772 won per household per year, respectively. According to the results of the survey, it seems that respondents think that marine forests are more valuable than marine ranches. This is as a result of ordinary citizens' thought that the marine ranches are more cost-effective than the marine forests. The benefits estimated through this study can be used for analysis of economic feasibility prior to carrying out the project of building marine ranches and developing marine forests, and are considered to be the valuable for policy-making purposes and finding social and economic consensus.

이번 연구에 사용된 깃비늘치는 2021년 2, 5, 8, 11월과 2022년 2, 4, 8, 11월에 우리나라 남해에서 저인망으로 채집하였으며, 채집된 깃비늘치의 전장범위는 16~73 mm였다. 깃비늘치의 가장 중요한 먹이생물은 난바다곤쟁이류와 요각류였으며, 그 외 단각류, 새우류, 곤쟁이류를 섭식하였으나 그 양은 매우 적었다. 깃비늘치의 영양단계는 3.16으로 나타났다. 크기군별 먹이생물 조성변화를 분석한 결과, <40 mm 크기군에서는 요각류를 주로 섭식하였으며, 성장함에 따라 난바다곤쟁이류의 비율이 증가하였고, 가장 큰 크기군인 ≥60 mm에서는 난바다곤쟁이류의 비율이 감소하고 새우류의 비율이 증가하는 결과가 나타났다. 개체당 평균먹이생물의 개체수는 유의한 차이를 보이지 않은 반면, 중량은 크기군이 증가함에 따라 유의하게 증가하는 경향이 관찰되었다.

전체 418개체의 참조기를 분석하였고, 전장의 범위는 12.0~27.5 cm였으며, 평균 전장은 19.6 cm였다. 참조기의 주먹이생물은 어류로 46.5%의 상대중요도지수비를 차지하였고 그 다음으로 난바다곤쟁이류가 우점하였다. 성장에 따른 먹이생물의 변화에 유의한 차이가 나타났는데, 성장하면서 어류의 섭식율은 증가하지만 새우류의 비율은 감소하였다. 계절적 변화는 여름과 가을의 고수온기와 겨울과 봄의 저수온기와 유의한 차이가 나타났다. 계절적 변화를 다변량분산분석(PERMANOVA)을 통해 분석한 결과, 계절에 따른 유의한 변화가 나타났다.

한국 서해에 출현하는 붕장어(Conger myriaster)의 식성을 알아보기 위해 총 158개체의 붕장어를 분석하였으며, 채집된 붕장어의 항문장(Preanal length)은 8.2~40.1 cm (±17.3 cm)의 범위를 보였다. 공복률은 30.4%를 보였으며, 위내용물이 발견된 붕장어는 110개체였다. 총 21개의 먹이생물이 출현하였으며, 그중 4개는 과까지, 1개는 속까지, 16개는 종까지 분류되었다. 붕장어의 가장 중요한 먹이생물은 54.4%의 상대중요도 지수비(%IRI)를 나타낸 어류(Pisces)였다. 어류 중에서도 멸치(Engraulis japonicus)가 우점하였다. 어류 다음으로 중요한 먹이생물은 새우류(Macrura)로 39.6%의 상대중요도지수비를 차지하였고, 새우류 중에서는 마루자주새우(Crangon hakodatei)가 가장 우점하였다. 붕장어의 성장에 따른 먹이생물 변화를 분석한 결과, 성장함에 따라 새우류의 섭식비율은 감소하였고 어류의 섭식비율은 증가하는 경향이 나타났다. 또한, 성장함에 따라 개체당 평균 먹이생물의 중량이 유의하게 증가하는 양상을 보였다.

The duty of disclosure it is a preliminary requirement to effect marine insurance contract between the assured and the underwriter. The contract of Marine Insurance is called a uberrimae fidei contract, the assured, therefore, in the law of marine insurance, shall communicate a material circumstances to the latter before the policy to be effected. As growing the maritime industries in Korea, there is forming a larger marine insurance market, accordingly, and having a wide relation with the practice of the marine insurance in England. It means that the most of the legal theories of the marine insurance would be adopted by the English Marine Insurance Case Law and M.I.A., 1906. From the viewpoint of the said this author has tried out to study what is the duty of disclosure of the marine insurance based upon the English Marine Case Law.

Harbour marine steel structures, which are served in severe marine environment, should be protected in appropriate method to reduce corrosion problems. Cathodic protection, one of the protection methods in terms of practical and economical point of view is being widely used to marine steel structures mentioned above. Recently it has been reported that the life of Al alloy anode with sacrificial anode for protection of harbour marine steel structures was shortened significantly than the original design life. In this study, the optimum cathodic protection design of harbour marine steel structures was investigated with parameter of sea water pollution degree.
