Recently, global terminal operotors are struggling to attract more cargoes into their ports through enlarging facilities and trying to be more efficient operotion Many researches on container terminal efficiency have been conducted, but most of the traditional studies are focused on the partial efficiency of the container terminal using quantitative questionnaires and basic statistical data In this paper, the Stochastic Frontier Model of the interaction among the variables was employed to execute numerical analysis on the efficiency of terminal. The objective of this paper is to measure the level of efficiency in the container terminals every year and to assess the influence in container terminal's efficiency on domestic and foreign terminals by changing the terminal scales and the level of input factors.

The waterfront has distinct climate characteristics different from urban or inland area. These may create not only the rise of energy and maintenance costs for facilities located at waterfront areas, but also the negative effects on the climate of the nearby inland area, unless these are treated with particular care. For the present study, the climate characteristics of waterfront were examined with climate data of 10 observation points carefully selected in Busan area. Each weather observation point was classified into either waterfront area of inland area, based on the distance from the coastal line. Special considerations were given to the climate data gathered at the Dae-Yeon weather station because it shows the climate characteristics similar to those of inland area, although it is located very near the waterfront area. Results indicates that this peculiar climate condition attributes, at least in part, to the reclamation of frontal coastal area.

This study is on the spatial composition of accommodation area in accommodation barge. The accommodation barge which is used as living facilities for offshore plants' workers can be classified into Accommodation Work Barge, Accommodation Pipe Lay Barge and Multi-purpose Accommodation Barge. We study on the spatial composition of accommodation area in Accommodation Work Barge, most frequently used, through analyzing G.A drawings of the barges. The spatial composition has great influences into the convenience and amenity for workers' daily life in the accommodation area of accommodation barge. The spatial composition of accommodation area shows many characteristics not in horizontal arrangement on any deck but in vertical space arrangement on layers of decks. The particular types of vertical space composition can be classified into 'Centralized Type' and 'Dispersive Type'. These two types will be the basis of space planning for new accommodation barge.

Currently many vessels determine an overhead obstruction by a rule of thumb based on their draft for maritime navigation. Therefore they doesn't have a good overhead obstruction clearance because vertical position of vessels varies on time by tidal. As a result, it is occurred maritime accidents that the mainmast of vessels is bumped against overhead facilities. And disaster by global warming and rising sea levels have increased casualties. So we feel keenly the necessity of warning system for not an earthquake but disaster wave such a tsunami. This paper analyzes a precise GPS ephemeris for maritime precise positioning to solve these problems. The precise GPS ephemeris provided by International GNSS service gives a difficulty to real-time application because of its sample interval. This paper proposes an effective interpolation method for real-time application, and it analyzes an accuracy of precise GPS ephemeris through an interpolation method.

Lab scale experiment study was carried out for biological treatment process development in shipboard. SBR(Sequence Batch Reactor) process with BM(Beneficial Microorganisms) was investigated for practical application on shipboard sewage treatment. From the results it was suggested that SBR process with BM might be a suitable process in terms of harmful materials removal. By adding BM to SBR system, the useful species of microorganisms and EPS(Extracellar Polymetric Substances) in sludge was increased. It was found that the biodegrability and harmful organic compounds like VOCs and harmful inorganic compounds like heavy metals. was reduced over 70%. As far as reclamation water is considered, this process is very advantageous to special environments such as cruise ships, because the method of adding BM makes it unnecessary to add other facilities on the SBR system.

Daesan Harbor is developing under the Industrial Complex or Petrochemistry Development Plan making the port the main hub-port in the West coast. Because of this development. the traffic volume is expected to increase to 9,1.95 incoming vessels by 2020, an increase of 167% compared to 2008 figure. This study thoroughly analyzes and evaluates a systematic and comprehensive use of the fairway in the Daesan Harbor. It establishes a future oriented and safe marine transportation environment upon appropriate examination of the total fairways and sailing assistance facilities.

Hamburg is going with the HafenCity Project to create new urban space for city's bustling central district. HafenCity will add an additional 155 hectares to Hamburg's central urban area, increasing its total area by some 40 percent. The new developments in HafenCity will be oriented towards the River Elbe and the great seaport. Its centre will have a close relation to water. They will be used for the construction of a fascinating mix of residential accommodation, offices, cultural and leisure amenities, retail facilities and restaurants set in a framework of an elaborate urban layout. This study is focusing on the purpose of the project goals, the task of the Hamburg authorities and GHS (Gesells chaft f$\ddot{u}$r Hafen und Standortentwicklung) and an urban planning ideas competition (draft masterplan). Regarding of the new trend of the reurbanisation in Europe, the aim of this study will be to find out, in which way Hafencity is trying to develope the new city district as a model for the European inner city of the 21st century.

Automatic Collision Prevention Training and RADAR Simulation Training, designated educations by the STCW Convention, are essential for officers to complete in order to board a ship. Recently, designated education institution standard based curriculum and requirements of the necessary facilities have been placed as a regulatory advisory requiring each institutions to match this and introduce equipment for simulation education, the FMSS(Full Mission Simulator System). Since the introduction of this research until today, a survey has been executed in order to find out the effect of utilizing the FMSS in ARPA/RADRA/Simulation Training for a period of 1 year. The result showed that 2.13times have been more effective. In addition, based on the results, identifying problems that occur during the education period and providing solutions to these problems have been proposed.

A theme park plays an important role as a preferred facility for attracting international and domestic tourists. Many local autonomies try to establish theme parks within their own territory. Busan Metropolitan City also places emphasis on hosting an outstanding theme park, and to be identified as the tourism destination toward the world city in 21st century. The purpose of this paper is to suggest tourism policy and management strategy based on the literature review and survey analysis to international tourists. First, it is needed to supply low land price to reduce construction cost and to invite investors. Second, the theme park has to have an attractive theme and new events for repeaters Third, infra structures related to the theme parks are necessarily provided for high accessability. Finally, more priority is placed on public relation for citizen and service education of the industry.

Maritime transportation engineering is a technical field that observes the flow of vessel's traffic in accurate and describes the feature of ship's movement statistically, then contributes to the improvement of traffic flow and the safety of traffic. The flow of marine traffic can be controlled by carrying out assessment and analysis of vessel's traffic. It can realize the safety of marine traffic by accurate research and analysis of vessel's traffic, understanding its flow and analysis data of vessel traffic. This study the analysis system of marine traffic connected with Radar, AIS based on ENC(Electronic Navigational Chart). The marine traffic analysis system contributes to safety of marine traffic through the design of marine traffic route, harbour facilities and improvement of vessel's traffic flow.
