In this study, numerical hull form development of a platform supply vessel, a full scale with the overall length of 26.75m, was performed to predict a bare-hull resistance and a large scale of model tests with a 1/10 scaled model were conducted to verify the success of numerical results. Numerical analysis on heave and pitch motion as a function of encounter frequency and ship's speed for the prediction of seakeeping characteristics are also presented. The experiment results of resistance agreed well with numerical analysis. As a result in the motion response characteristics, the heave RAO indicates high values with the range of encounter frequency 1.8~2.0. The Pitch RAO indicates high motion response characteristics at Beaufort scale No. 3 and 4 in rough seas.

This research analyzes whether the curricula of the designated educational institutions which cultivate fishing vessel officers are properly coordinated to fulfill the requirements of an international convention and the designated compulsory courses. It also compares these with the educational curriculum published by the designated educational institutions in 2013 with the STCW-F Convention and IMO Model Course. The outcome of this research shows the curricula operated by the designated institutions fulfills the standard of The Ministry of Maritime Affairs and Fisheries. However, some of them do not meet the requirements of the STCW-F Convention and IMO Model Course. The compulsory coursework for marine technicians comprise 21 to 34 credits, compared to the 64 compulsory credits approved by maritime university. For the last five years (2008-2012), 555 out of 833 graduates have earned marine technician licenses, which accounts for 62% of the total. In preparation for ratifying the STCW-F Convention and in accordance with IMO Model Course and the minimum requirements of STCW-F Convention in the near future, improvements to the curricula are recommended.

This paper studied the feasibility for utilization of the automatic fishing information recording system, which stores and manages navigational information and fish catch results of a fishing vessel in a portable storing device, in order to help promote the systematic management of fishing information by offshore and coastal fishing vessels. Position accuracy was within 10 meters on the position accuracy experiment using GPS module. Characteristics of navigation according to the navigation, anchoring and fishing operation showed the difference of navigation track information for GPS, and fishing possibility of fishing boat could be estimated through the analysis as the utilization result of system for the large pair trawl and large purse seiners. In particular, it is impossible to provide false positional information by arbitrarily operating the system, and it may be possible to present the factual results of fish catch by date, fishing ground, and fish species by comparing the fishing information with fish catch. Such contents are considered to be useful as basic data for the management of fisheries resources.

Recently, ships' average navigation speed become faster than before because of the increasing of high-speeds vessel including container ships and passenger-ferries. So, it is considered that the speed limit in the navigation channel in Korea isn't proper for vessel management in these days. Also, there is rare paper studies about the speed limit quantitatively and numerically, especially the speed limit is discussing continuously, as abrogation of Incheon Port's speed limit and alleviation of Gwang-yang Port's speed limit according to the requests by the navigating mariners. Consequently this paper deals with the effectiveness of speed limits using the Environmental Stress Model, after replay of the navigation traffic flow in the straight waterway using marine traffic flow simulation technique.

The fishery compensation by marine spatial planning such as routeing of ships and offshore wind farms is required objective data on whether fishing vessels are engaged in a target area. There has still been no research that calculated the number of fishing operation days scientifically. This study proposes a novel method for calculating the number of fishing operation days using the fishing trajectory data when investigating fishery compensation in marine spatial planning areas. It was calculated by multiplying the average reporting interval of trajectory data, the number of collected data, the status weighting factor, and the weighting factor for fishery compensation according to the location of each fishing vessel. In particular, the number of fishing operation days for the compensation of driftnet fishery was considered the daily average number of large vessels from the port and the fishery loss hours for avoiding collisions with them. The target area for applying the proposed method is the routeing area of ships of Jeju outer port. The yearly average fishing operation days were calculated from three years of data from 2017 to 2019. As a result of the study, the yearly average fishing operation days for the compensation of each fishing village fraternity varied from 0.0 to 39.0 days. The proposed method can be used for fishery compensation as an objective indicator in various marine spatial planning areas.

The authors investigated the present status of employment of graduates from ship-boarding departments, Department of Fishing Technology, of Marine Engineering in National Fisheries University of Pusan from 1974 to 1988 by communication of every kind. The prospects of the graduates were studied on the bases of the present status of employment The results obtained can be shown as follows ; 1. In Department of Fishing Technology, the number of graduates who are engaged in major field is 562 (81%) among total members of graduates 693, and fishing vessel officer and fisheries company officer is 308(55%), 215(38%) respectively among the above members of employment in major field. 2. In Department of Marine Engineering, the number of graduates who are engaged in major field is 468(74%) among total members of graduates, 634, and engine and machinery field officer, merchant vessel officer is 331(71%), 89(19%) among above members of employment in major field respectively. 3. Developement of deep sea fisheries and industry of engine and machinery seems to graduates easy to get their jobs in major field.
