This paper aims to improve survival ratio at ship fires by soot density reduction This study examines soot density and visibility using FDS. And also examines evacuation time by Pathfinder. The FDS(Fire Dynamic Simulator) is a 3 zone model(Field Model) analysis tool and the patherfinder is a useful analysis tool for evacuation. This research examined about evacuation time using the current regulations of the ship's corridor width and exit width first And then studied evacuation time again when ship's structure was changed according to the method that is proposed in this paper. And finally compared the results each other.

부산 수영만 해상케이블카 설치예정수역에서 파랑 및 유동환경에 대한 기본 자료 조사와 아울러 대상해역에서 구조물을 설치하였을 때 주요 입사파에 대한 파랑 및 유통환경 변화 특성을 수치모텔 시뮬레이션으로 분석하여 타당성을 검토하고자 하였다. 대상해역에서 광안대교가 설치된 조건이나 이의 외해측으로 일련의 해상케이블 지지구조물을 설치함에 따라 발생할 수 있는 환경 중 해저저질의 이동 및 표사에 영향을 미치는 파랑과 유동장 해석을 대상으로 하였다. 파랑해석은 SWAN 모델을 이용하여 분석하였고, 유동장 해석은 MIKE21 HD 모듈을 이용하여 해석하였다.

울산신항의 활발한 개발로 인하여 기존에 설치되어 있던 온산항북방파제는 원래의 목적인 방파제로서의 기능은 사라지고, 울산항 3항로에 간섭된 지장물이 됨에 따라, 기존방파제의 철거를 수행하였으며 철거순서는 상치 콘크리트 깨기, 속채움 제거, 케이슨 절단 및 천공, 인양 및 제거, 케이슨 파쇄의 순서로 진행되었다. 특히, 파쇄한 콘크리트는 크라싱 작업을 통해 재생골재로 생산하였으며, 향후 신설케이슨의 속채움 재료로 재활용하는 것으로 하여 경제적 자원재활용에도 기여하고 있다.

Many studies on BIM-based design, construction and operation have already been conducted on roads, railways, etc., but BIM research in the ports and harbors is still lacking. This research develops BIM Library and Technical contents focused on practical usability of ports and harbors infrastructure. We have developed technical content by applying various User Interfaces and workflows, considering the characteristics of ports and harbors design. In order to examine the practical utility of the developed library and contents, we tried modeling the breakwater using these. As a result, we confirmed that collaboration of BIM library and technical contents could significantly improve the productivity of BIM design by increasing library usage and automating repetitive tasks.

Most of Cities are suffering from the traffic congestion problem with the vehicles increased. Especially, the City of Pusan is experiencing the severest traffic congestion with the lower read capacity and the higher travel demand than any other cities in the country. Thus, the purpose of this study was to grasp the conditions, review the problems and finally suggest the improvements which we faced at this time for the construction of the Urban Transportation System considered in Pusan area. Based upon the results, it was concluded that firstly the Urban Transportation System(UTS) in Pusan area should be constructed by the Public Transportation System in the center of the Public Transit Modes(i.e., bus and subway), secondly the Para-transit Modes(i.e., Light Rail Transit, LRT) introduced, and thirdly the Transportation Demand Management(TDM) implemented with the expansion of the transportation facilities if possible.

Tidal current and water level change in coastal waters are formulated in terms of mathematical models. A systematic discussion of the derivation of a set of governing equations, expressing conservation of mass and momentum is presented. A simplification is introduced by integrating all variables and equations over the total water depth, the Solution of the formulated problem is achieved by using the finite difference method(FDM). The applied study area is taken from Mokpo harbor and its adjacent coastal water which have significant hydrographical changes due to the construction of the estuary barrage and land reclamation work of estuary barren. Some comparisons with the observed current and water level changes the numerical solutions are found to be considerably fit well for the recent coastal water motion.

With the modernization fund of the government, construction of new passenger ships make the level of interior design is improved, but the space where the crew is working is still inadequate. This study is to investigate the color environment of the Bridge Deck and Engine Room among working spaces of passenger ships. It aims to improve the mental health of crews and set up a safe working environment by presenting color design, and suggest the specificity of ship's working space and color value with matching the color environment.

It can be replaced with a smart work service centering on tasks that do not require on-site work among container terminal tasks. Here, the cloud service is helpful for small and medium-sized stevedoring companies as it reduces the cost and time required for initial system construction, and allows you to pay usage fees as needed. This study introduces a case study on the development of web services that comply with industry standards so that advanced ICT can be used in connection with the terminal operation system.

A ship's maneuvering motion model is important in a computer simulation, especially under the trend of intelligent navigation. This model is usually constructed by the hydrodynamic parameters of the ship which are generated by the principles of hydrodynamics. Ship's motion model is a nonlinear function. By using this function, ships' motion elements can be calculated, then the ship's trajectory can be predicted. Deeping neural networks can construct any linear or non-linear equation theoretically if there have enough and sufficient training data. This study constructs some kinds of deep Networks and trains this network by real ship motion data, and chooses the best one of the networks, uses real data to train it, then uses it to predict the ship's trajectory, getting some conclusions and experiences.
