The main objective of this study is to determine the methodology to increase the practical use of future Marine GIS based on the user's point of view of the analysis of maritime & fishery government agencies's roles. GIS related job duty of two Busan District offices of MOMAF(Ministry of Maritime and Fisheries), NFRDI(National Fisheries Research & Development Institute), Korea Institute of Maritime and Fisheries Technology and marine & fisheries local government offices of Busan Metropolitan city were analyzed for the establishment of MGIS, future extended service targeting user's increased practical utilization. Several suggestions in the area of production mechanism and technical policy for marine geographic information among the government agencies are developed to settle down successfully MGIS in Busan. Furthermore, 10 fields of Marine Geographic issues are rearranged for intending the desirable system and service.

In this study, heavy metal in road-deposited sediments (RDS) and marine sediment around Gwangyang Bay area have been investigated to assess the pollution status of metals and to understand the environmental impact of RDS as a potential source of metal pollution. Zn concentration for <63 ㎛ size fraction was the highest (2,982 mg/kg), followed by Cr, Ni, Pb, Cu, As, Cd, and Hg. Metal concentrations in RDS increased with decreasing particle size and relatively higher concentrations were observed around the metal waste and recycling facilities. For particle size in RDS smaller than 125 ㎛, EF values indicated that Zn was very high enrichment and Cr, Cd, Pb were significant enrichment. The concentrations of metals in marine sediments were mostly below the TEL value of sediment quality guidelines of Korea. However, the Zn concentrations has increased by 30~40% compared to 2010 year. The amounts of Zn, Cd and Pb in less than 125 ㎛ fraction where heavy metals can be easily transported by stormwater runoff accounted for 54% of the total RDS. The study area was greatly affected by Zn pollution due to corrosion of Zn plating materials by traffic activity as well as artificial activities related to the container logistics at Gwangyang container terminal. The fine particles of RDS are not only easily resuspended by wind and vehicle movement, but are also transported to the surrounding environments by runoff. Therefore, further research is needed on the adverse effects on the environment and ecosystem.

In the present trends at which vessels would be supersizedly designed for adapting special cargoes in order for effective controls of logistics in marine transportation, it brings poor manoeuvrability of ships and makes environmental or economical loss seriously due to accidents of a large scale at sea. International Maritime Organization adopted manoeuvring standards and also recommended manoeuvring booklets for ship operators recently. We attempted to find variation of hydrodynamic derivatives when a bare hull was fitted with propeller and rudder, or propeller only by captive model test in the circulating water channel. On comparing experimental results with theoretical values derived from equations, almost same tenden-cies were found at hull-propeller-rudder and hull-propeller situations. Interactions with rudder displayed well at large drift angles.

In 1990s the debate on very large ships made the Mega ship and mega port concept emerge. Many studies have bees done on such big ships by consultant, naval architects, port designers, ship operators, economists etc,. with different points of view and results. This paper, by reviewing the literature systematically, identifies limitations and major issues, and suggests directions for further studies.

We tried to find the optimal growth conditions of sea cucumber and to analyze the economic effectiveness of the sea cucumber seedling release project in Korea. We first examined the optimal growth conditions of sea cucumber in the relating literatures. Then, we analyzed the economic effectiveness of the sea cucumber seedling release project of the Woncheon fishing village union of Gyeongnam Province in 2016-2018 by using the cost benefit analysis method. The net income of the release project of the Woncheon fishing village union was 69,850 Korean won. The benefit to cost ratio of the sea cucumber seedling release project of the Woncheon fishing village union was estimated to be 1.7, indicating that the project was economically feasible. In order to improve the economic feasibility of the sea cucumber release project, as we see in the case of the Woncheon fishing village union, it is necessary to manage the purchase of the sea cucumber seedling, to improve the recapture rate of sea cucumber, and to manage marketing of sea cucumber.

In this paper, we explore a novel transportation container in the marine terminals. The container includes Smart Tag embedded with radio frequency(RF) chips, which is used to access information about productions and possibly incorporated with GPS systems for integrated managements of them. The proposed mechanism is valuable for decreasing cost, increasing satisfaction of customers, and preventing economic loss due to production missing, thus increase of economic efficiency is highly anticipated. Consequently, accurate and proficient management is considerably accomplished in overall procedures of inventory and currency by means of the proposed systems.

통신기술이 1 세에서 5 세대로 발전하는 동안 해상물류의 핵심인 컨테이너는 기능상의 큰 발전없이 과거에 머물러 있다. 이에 본 논문에서는 컨테이너의 위치 및 상태 정보를 수기로 관리하던 기존의 방식에서 벗어나 IoT 장비를 활용해 실시간 위치 파악, 상태 모니터링 및 자동화 등을 통해 물류의 가시성을 확보하고 컨테이너를 효율적으로 재배치함으로써 비용 절감 및 새로운 서비스 창출하기 위한 스마트 컨테이너를 제안한다. 부가적으로, 태양열판을 이용한 전원공급, 펠티어 소자를 이용한 냉방기능을 제공함으로써 신선 식품 배송의 핵심인 풀 코드 체인(Full Cold Chain) 플랫폼으로 활용범위를 넓히고자 한다.
