In the present maritime traffic conditions of Gwangyang harbor, there exists many hazardous factors which may lead to huge accidents including marine oil pollution. To mitigate the danger to vessels in Gwangyang harbor and to secure the safety of maritime environment, we established one way traffic between No.3 Route and No.4 Route, Designed of deep water line on No.3 route, Extended one-way route for Myo-Do Passage etc.

Recently many researchers are keen interested in the concept of ubiquitous using mobile internet and RFID. Busan also plans to build a first U-city in the areas of port logistics, traffic, tourism convention, medical service. It is important to be accepted by consumers for U-tourism convention service adoption to determine the future growth potential. The purpose of this paper thus examines the effect of tourism contents on U-tourism convention service adoption using technology acceptance model.

Mt. Yokmang landscape design awarded first in [North container terminal site furtherance construction in Busan new port], design competition sponsoring in the Korea Container Terminal Authority in 2005. Design guideline was to propose the symbol of new port and to establish landscape plan in consideration of view and geological location. Because landscape plan required establishment of restoration plan for cutting slope, Mt. Yokmang became the major object. The purpose of planning are as follows. The first purpose is to minimize existent natural environment damage, and the second, to connect with ambit and create new image. The third is to provide place of rest and interchange for local resident. Reflecting stratum structure and landscape characteristics, cutting slope consisted of [utilization slope], [presentation slope], [landscape slope], and [ecological slope]. Vegetation design applied ecological restoration method through restoration of stratum, and eve environment-friendly afforestation, planned program that can connect area with existing ecosystem. In process that decides form of the cutting slope, analyze view structure and visual exposure in various access routes, sensitivity etc. was accomplished. Also, symbolic tower(Ocean Polaris) that presents in architecture and landscaping features, night landscape planning could gain synergy effect by keeping consistence with landscape and ecological planning. Passing through final design and construction process, I expect that the Mt. Yokmang will be a new landmark in Busan new port.

국제해사기구(International Maritime Organization)는 선박 평형수로 인하여 발생하는 환경문제를 방지하기 위하여 지난 2004년 선박 평형수 관리 협약을 제정하였고, 2016년 핀란드의 비준함에 따라 2017년 9월 8일부터 발효될 예정이다. 이 협약에 대응하기 위하여 선박 평형수 처리기술이 개발되어 승인이 되었다. 이중 수중방전을 이용한 기술은 화학약품의 첨가 등이 없어 경제적이고 내부에서 발생하는 OH라디컬, 자외선, 충격파, 전기장, 오존 등에 다양한 요소들에 의하여 수처리가 가능하고, 중화를 위한 첨가제 등이 필요없어 친환경적이다. 본 연구에서는 부산 항만 근처연안에서 채취한 바닷물을 대상으로 수중방전을 이용한 방법을 연구하였다. 실험방법은 그림1과 같이 Point to Point 방식의 전극을 꾸몄고, 용액은 1L이며, 전압은 8kV, 30kHZ로 가해주었다. 광학분석장비(OES)를 이용하여 수중방전시 발생되는 빛 분석을 하였다. 실험결과 OES분석 결과 살균작용하는 OH 라디컬이 발생하는 것을 확인할 수 있었다. 또한 실험 도중 시료를 채취하여 $35^{\circ}C$ 48시간동안 배양하였다. 배양 결과 시간이 경과함에 따라 미생물의 개체가 그림 2와 같이줄어두는 것을 확인할 수 있었다.

This paper introduces a new method of improvement for marine soft ground, MLPP (Marine large Pack Pile). The MLPP is a reinforcement technique far the conventional SCP or GCP piles by confining them with geotextile pack. A pilot project at Busan New Port site and laboratory model tests were carried out to investigate the settlement reduction and bearing capacity enhancement effect of pack pile. The results of field and laboratory tests show that MLPP method can be a safe and economic alternative method for SCP and GCP.

The Korean government establishes a strategy to develop the Busan New Port as a world ranking two transit-oriented port. This paper aims at presenting an efficient Inter-Terminal Transportation system in the Busan New Port as a method of achieving the government strategy. It proposes four systems to treat Inter-Terminal Transportation in the port; Double stack Multiple Trailer System (DMTS) Rail-based transportation system, Private road for Inter-Terminal Transportation, and platform for Inter-Terminal Transportation. This is shown to highly potential for efficient Inter-Terminal Transportation in the port.

Estimation of wave height is the most important factor in the design of coastal structures such as breakwaters. In the present study, typhoon wind distribution was constructed by applying the parametric model of Holland (1980), and numerical simulations on the typhoon-generated waves were carried out using the WAM. The typhoons which affected the southern coast of the Korean Peninsula and several hypothetical typhoons were selected to construct the training sets. Design wave heights were estimated using the empirical simulation technique for various return periods and wave directions. The estimated design wave heights were compared with those by the peaks-over-threshold method and the results of KORDI(2005).

Recently, the increasing trend for the transshipment traffic of Busan port in Korea is slowing down because of the extensive development plan of domestic ports in china. For solving this problem, Korea is going on the project for preoccupying the transshipment port for attraction of port traffic from the newly potential markets(NPM) based on the Northeast Asia area. As a part of the project, this paper proposes the efficient methodology for selecting the optimal shipping network and strategic transshipment port within NPM using the mathematical models and simulation analysis. For that, we firstly find the alternative transshipment ports within NPM through the status analysis of the current port traffic and shipping network and then, we choose the candidate transshipment-ports in order of minimizing the transport costs through the mathematical approach. With the scenarios based on the selected transshipment-ports, we perform the simulation analysis for choosing the optimal transshipment-ports and the shipping network minimizing the total costs and times concurrently. We expect that the results of this paper will be used efficiently when korea select the strategic transshipment-port in the future.

This paper aims to determining the optimal capacity of Pusan port in view point of Container Physical Distribution cost. It has been established a coast model of the container physical distribution system in Pusan port is composed of 4 sub-systems and in-land transport system. Cargo handling system, transfer & storage system and in-land transport system, and analyzed the cost model of the system. From this analysis, we found that the system had 7 routes including in-land transport by rail or road and coastal transport by feeder ship between Pusan port and cargo owner's door. Though railway transport cost was relatively cheap, but, it was limited to choose railway transport routes due to the introducing of transport cargo allocation practice caused by shortage of railway transport capacity. The physical distribution ost for total import & export container through Pusan port was composed of 4.47% in port entring cost, 12.98% in cargo handling cost, 7.44% in transfer & storage cost and 75.11% in in-land transport cost. Investigation in case of BCTOC verified the results as follows. 1) The optimal level of one time cargo handling was verified 236VAN (377TEU) and annual optimal handling capacity was calculated in 516, 840VAN(826, 944TEU) where berth occupancy is $\rho$=0.6 when regardless of port congestion cost, 2) The optimal level of one time cargo handling was verified 252VAN (403TEU) and annual optimal handling capacity was calculated in 502, 110VAN (803, 376TEU) where berth occupancy is $\rho$=0.58 when considering of port congestion cost.

This study aimed to reduce of traps incident of metro train door by suggesting preventive actions throughout analyzing why railway drivers and passengers commit unsafe behaviors which are human factors making occurrence of the incidents. The incident cases were analyzed and Incident Tree was structured by brainstorming with safety experts. In addition, the questionnaire survey was conducted for comparison with the analysis results. As the result, this study suggested driver's factors, passenger's factors, and public relation plan for safe use of metro in order to reduce the frequency of the incidents. For driver's factors, implementing job-rotation systems between railway and non-railway drivers, installing Object Detection Sensors between the metro doors and PSD, and flexible operation of dwell time were suggested. For passenger's factors, placing a platform safety person, installing a safety fence in front of the stairs and the elevators, and country wide public relations through mass media were suggested.
