본 연구에서는 연안의 해저면에 누적된 퇴적오염물을 효율적으로 수거할 수 있는 저속 쌍동형 정화선에 대한 선수선형의 개념설계에 대해 수행하였다. 선형설계는 선체건조가 용이하도록 단순화하였으며, 쌍동선 선형의 선수 Water line, 선수각 등의 변화에 따른 저항성능의 영향을 검토하였다. Ansys CFX를 이용한 수치시뮬레이션과 회류수조에서의 모형시험결과와의 비교/분석 등을 통하여 선수부 선형변화에 따른 저항성능과 자유표면 유동특성 사이의 관계를 고찰하였으며, 그 결과 선수재 위치와 어깨부 체적의 선수부 이동에 따른 파형개선으로 조파저항이 감소하는 등 저항성능의 향상을 확인하였다. In this study, conceptual design of the fore-body hull form of catamaran type dredging vessel was performed that can effectively remove the contaminated sediments in coastal seabed. The hull form was simpled for the easy hull construction and the resistance performance was investigated to find out the effect of hull form parameters between variation of waterline and angle of entrance, etc. The relation between resistance performance and characteristics of free surface flows according to variation of bow forms was investigated by model testing in the circulating water channel and using Ansys CFX. The improvement of ship resistance performance to the wave resistance decrease due to improved wave pattern has been verified according to move the stem and the volume of the shoulder to the fore part of the vessel.

The nesting of parts cut on raw steel plate has been a subject of interest to the shipbuilding industry for many years. "Nesting" is defined operation of layout of the parts on the raw material with minimizing the waste rate. Therefore, it is very important to optimize the cutting area. Since the existing nesting programs are prepared for expensive workstations and the expert, it is needed to develop nesting program for personal computer to improve the technology of small/middle sized shipyards and their productivity. This study involves development and application of appropriate optimization technique to solve the problem of plate nesting. And the appropriate D/B for storing nesting data developed, the function of D/B is introduced in this paper.

This study, which is intended to increase the safety of highly utilizable 28ft class leisure boat with side-fin, has been confirmed by the model test of expected stability and rolling damping test in CWC(circulating water channel) at Chosun University. Especially, the problems of stability in small boat have occurred frequently. In order to solve those problems, the current status and regulation of the stability have been analyzed and the research to improve the stability of leisure boat has been conducted. As a result, the model of a ship with perfect designed side-fin has better righting arm and rolling damping factor than those of current model ship. Consequently, this study has enhanced the stability of popularized 28ft class leisure linear vessels, and it is also expected to make good use of leisure ship``s basic design.

The marina port facility that need to a fixed temperature is affected by a lot of external force caused by ship wave due to frequent traffic count around the coast. These waves function as main cause that inhibits the stability of the moored sailing vessels and port facilities. In this study, Harbor and marina facilities are installed to secure sea waters and water tank tests were carried out numerical analysis. Fixed floating structures due to changes in wave height and fluid mechanical properties was evaluated. Marine environment was calculated according to the reduction of the wave. And the stationary floating structures due to changes in the shape of the wave characteristics and wave height suggests a stable shape. The relate wave stabilization was identified in the condition of Multi-body of flat panel and flat floating structure and expecially in the condition of λ/L=6.35, the wave stabilization was about 25% higher than water tank test of multi-body floating structure.

A practical method to investigate the sharing architecture of FMS, for small and medium enterprises, on distributed heterogeneous environmental conditions is investigated. Because the industrial FMS model requires a reasonable size for actual work-site flexible operation, the initial facility expense is very heavy. The support for flexible cooperation of FMS, with some external different FMS, can reduce expenditures and provide greater functionality. While most FMS provide their operation process using an adequate mechanism, when used in isolation, such as island of automation, there is increasing demand for FMS that can cooperate. By exchanging intermediate products and information with other external FMS, products can be produced that cannot be produced alone, such as those that require various processes. This study first considers the sharing architecture of FMS for small and medium enterprises, and investigates the effects of the general sharing architecture of FMS on distributed heterogeneous environments, by using transducer approach to agentification. In this study, set-up station or in-out station takes charge of the gateway of intermediate products, and routes them among distributed heterogeneous FMS plants. The transducer approach is applied to web agent and set-up agent established interfaces, with system controller and setup controller. In this study, the FMS-established sharing architecture is able to obtain not only the internal flexibility, but also the external flexibility.
