  • As the era of e-navigation begins, the significance of harmonized collection, exchange, and integration of marine information conventional "ship-to-ship" and "ship-to-shore"/"shore-to-ship" has become more significant in ensuring safety and security at sea. This research aims to provide an internationally applicable list of Standard e-Navigation Phrases (SENP ) for communication in the e-Navigation environment, along with practical approaches to this. For this purpose, the importance of standardized communication phrases specific to e-Navigation will first be illustrated. In order to approach the e-Navigation phrases in a practical and pragmatic manner, means of compiling and processing authentic VHF linguistic data accumulated from one of the Korean ports, Ulsan, will be detailed. In addition, major outcomes to be considered in designing SENP will be suggested. Finally, future actions and a joint effort for the standardization of e-Navigation phrases among stakeholders will be sought.

  • Two species from the genus Escharoides Milne Edwards, 1836, E. biseriatata and E. buffonellarioides n. sp. Were first found in Korean waters in this study. Their colonies were collected from two locations in the South Sea, Korea: Tongyeong Marine Ranch in 2004 and Daebyeon Port in 2009. Escharoides biseriatata shows a difference in the position of avicularia from the Chinese specimens. While avicularia are lateral to the orifice in Chinese specimens, the ones in Korean specimens seem to be located more latero-proximally. Since Escharoides biseriatata was reported as fouling bryozoans in China in 2001, this species first occurred at Daebyeon Port in Korea in this study. Escharoides buffonellarioides n. sp. is similar to E. adeonelloides in morphological features of zooids but is clearly distinguished by having the erect colonial form of small masses. With the addition of two species reported herein, four Korean Escharoides are recorded: E. biseriatata, E. buffonellarioides, E. excavata, and E. sauroglossa.

  • IMO MSC 에서 제안된 E-Navigation 개념은 전자정보통신기술에 기반한 선박과 육상간 해양정보의 수집, 통합, 교환, 표현, 분석 풍을 통해서 항행 안전과 효율을 높이고, 해양환경을 보호하는 항행서비스를 개선하는 것이다. E-Navigation 전략을 개발하고 E-Navigation 환경을 구축하는 과정에서 해상교통환경의 주체가 되는 관제센터와 운항 선박의 정보교환 연동 시뮬레이션은 E-Navigation 환경 구축에서 중요한 의의가 있다. 육상-선박간 연동 시뮬레이션을 통해서 E-Navigation의 다양한 정보 교환의 기술적 가치와 새로운 교통환경의 안전성과 효율성을 평가할 수 있다. 본 연구에서는 항만 관제 모의를 수행하는 VTS 시뮬레이터와 선박운항을 모의하는 선박운항 시뮬레이터를 통합 운영하여 고급의 교통 정보를 양방향으로 교환하고, 각 선박마다 차별화된 교통 정보를 제공받을 수 있는 방안을 마련하기 위한 E-Navigation 환경을 시뮬레이션하는 시스템을 연구하였다.

  • From the economic point of view the fishing port is the complex of installations on land, organized to serve the fishing fleet and its cargo, and is the main link in the production chain of all components of the fishing industry, with the aim of achieving the planned targets with the minimum cost. Fishing port investment decisions have had significant impact on the development aims of Korean fisheries. Fishing port investments in Korea are made mostly by public or semipublic port authorities. Such investments should be judged not purely on the basis of financial profitability but rather on the extent to which they serve the development aims of the fishing industry. This makes the economic appraisal process more complex and presents certain problems in correctly quantifying the economic costs and benefits of the fishing port projects. This study concentrates more on the theoretical economic appraisal models than on the purely financial aspects of fishing port investments and points out the difference between the two approaches. In the result, there is clearly an element of judgment as to whether or not a shadow price needs to be used in estimating economic benefits and costs. From this viewpoint, some attempts are made to provide definitions of the possible economic benefits and costs, and methods for estimating and evaluating them in Part III and IV. Especially queueing theory is applied in the calculation of economic benefits. When a project is contemplated and analysis shows it to Lave a positive NPV, one question that arises is whether it should be implemented now or delayed. In this paper, the first year rate of return method is regarded as a more concise way of solving the timing of investment, At the end of Part IV, risk analysis of fishing port investments is considered. It can be handled in a number of ways, ranging from informal judgment to complex statistical analyses involving large-scale computer models, This paper recommends that evaluators of fishing port investments use the sensitivity analysis indicating exactly how much NPV will change in response to a given change in an input variable, other things held constant. Decisions regarding the amount of capacity to provide must be made in fishing port investments. Providing too much service would involve excessive capital costs. On the other hand, not providing enough service capacity would cause the waiting line of fishing vessels to become excessively long at times. Therefore, in Part V, the optimal number of berths and berth productivity in fishing port are defined as follows: Minimize E(TC) = E(WC)+E(SC) The minimum of this function is the solution and that is the optimal number of berth and berth productivity in fishing port.
