공항의 용량측정은 수요군의 흐름에서 발생하는 소비시간분석을 요구하며 공항체계 의 대부분 시설에서는 흐름의 시간변위를 연속대기례에 의한 비효율적방법으로 예측할수도 있으나 청사내의 여객동선에 대해서는 여러 시설을 활용하려는 여객의 선택선호로 인하여 확률적 접근이 바람직하다. 본 논문은 공항의 청사내에서 부대시설에 의하여 소비되는 여객 의 이완시간을 예측하는 모형을 개발하였다. 총이완시간은 여객이 각 시설을 이용하는 확률 과 이용시간의 기대치에 대한 함수로서 계산되었으며 정상적인 여객의 동선이 이들 시설에 의하여 영향을 받을 경우에만 정의되도록 하였다. 이 이완도는 연속된 청사의 기능시설에 대한 여객동선분포의 입력과 출력을 설명하는데 쓰이게 되며 나아가서는 청사전반의 용량산 정을 위한 지표를 제공한다. 모형 검증을 위한 자료는 매표대와 보안검사대 사이의 부대시 설을 중심으로 수집되었으며 자료의 특성과 모형의 심요성이 논의되었다.

At a passenger terminal which is a core facility of a large-scale airport, users are not easy to recognize its space and to approach each facility by composition of large-scale space not recognized at a glance and arrangement of complicated functional space. Such a passenger terminal should be designed by putting a focus on functionality, safety and convenience since diverse passengers use it. At a passenger terminal, a lot of passengers' circulation followed by diverse purpose appear. Therefore, it needs a lot of functional space and space to satisfy passengers' demands. When circulation is planed, it should be designed by a systematic standard. The study was carried out on the basis of international airports, considering features and functions of airport circulation system. In kind of circulation in passenger terminal of an airport, there are user's circulation (passenger's circulation, employee's circulation and service circulation) and baggage circulation. The study examined passenger's circulation which was a major circulation of passenger terminal out of user's circulation. The study examined elements which had an effect on circulation system at a large-scale airport passenger terminal and basic data for an efficient circulation system standard of passenger terminal through case analysis of passenger terminal circulation systems at international airports.

크루즈 관광에 대한 인식과 생활수준 향상으로 크루즈 관광에 대한 수요가 급증하는 추세이다. 그러나 기능중심으로 발전된 항만시설은 크루즈 여객선 터미널의 건설에 대한 대응력이 미약한 실정이다. 따라서 다이어그램을 통해서 계획 된 요코하마 여객 터미널의 동선 및 배치계획을 바탕으로 크루즈 터미널에 적합한 공간설계의 기술개발을 목표로 한다.

동북아시아지역에서 인천국제공항이 최고의 허브공항으로서 역할을 위해서는 무엇보다도 환승율에 대한 연구가 필요하다고 판단된다. 인천국제공항은 2005년도에 3,054,485만명의 환승여객을 처리하여 환승율은 11.9% 를 기록하였는데 이는 동북아시아의 경쟁허브공항의 환승율인 30-40%와 비교해보면 공항경쟁력이 상당히 뒤쳐진다고 할 수 있다. 이러한 약점을 보완하기 위하여 여러 가지 관련 인자들을 검토하는 것이 중요하다고 판단되어지는데 그중에서 인천국제공항의 비행편최소연결시간(MCT)을 개선하는 것이 필요하다. 이러한 문제를 개선하기 위해서는 항공기 스케줄, 항공사 배치, 게이트 배정방법, 수하물처리, 여객 동선 등이 함께 검토되어야 할 것이다. 그러나 이러한 인자들에 대한 세부적인 분석이 단기간에 걸쳐 해결되는 문제가 아니기 때문에 본 연구에서는 외국 허브공항의 MCT 수준, 관리방법, 국외사례 등을 고찰해 보고 동북아시아에서 허브공항을 향한 인천국제공항의 환승율 제고차원에서 정책적 방안을 제시하고자 한다.

In the development of railroad station area, there are many factors about business management, but the interest of railroad users is an important factor as customer satisfaction. It is necessary to have the quality estimation of railroad service, and important factors of service as customer satisfaction aspects can be supply, reliability, convenience, and safety. In this study, primary factors are deduced in the efficiency aspects of railroad station facilities from analyzing relative importance index using AHP(Analytic Hierarchy Process) methods. The most high rank important factor is railroad station user facilities, and the AHP importance index of passenger facilities and elevator facilities for KORAIL personnel and facility users is index. The third of KORAIL personnel is movement facilities, but facility users index is sanitation. And the low important factors of KORAIL personnel and facility users are shown as the platform in passenger facilities, the rest facilities in waiting room, the escalator in going up and coming down facilities, the escalator in movement facilities, the raised letters block in guide facilities, and the parking lot in subsidiary facilities.

One of good ways to make a ship perform well in rough seas is to reduce its waterplane area and accordingly is subject to a reduced wave exciting forties. However, a great reduction of the waterplane area may create a penalty in speed performance due to the increased ratio of the wetted area to the displacement volume. This paper suggests a new catamaran hull form which compromises the speed and seakeeping quality by increasing the waterplane area somehow compared with that of the conventional SWATH ship. A 350 passenger carrying SWATH ship with a cruising speed of 30 knots in sea state of 4 has been developed and its performance was validated by the model tests. The design concept resistance performance and seakeeping dualities of the design craft are presented together with its comparative performance comparison with other high speed crafts.

A very good seakeeping vessel is able to operate effectively even in high sea states and also the passengers and the cargos are ensured in good conditions. The motions of a high speed boats are highly influenced by speed and dynamic forces even in encounter frequencies so that the assessment of seakeeping ability of the design craft in an early stage needs to be calculated for all three motions and for all ralative wave headings. In this paper, it concludes that RAO and RMS values of the catamaran's 3 motion are calculated according as the variation of Beafort scales and ship's speed. The ship motion response of the catamaran based on the RAO and RMS by encounter angles and speed was calculated.

Since 2000, many local governments have been trying to introduce trams because of the government's failure to adopt environment-friendly policies and light rail. However, there is no service evaluation system that can maintain and enhance tram users' convenience, safety, and comfort during operation. In addition, the tram characteristics are not reflected in the application of the evaluation system of "management and service evaluation for public transportation operators" which is being implemented to railway operators or bus transportation operators. The purpose of this study is to develop the evaluation criteria of operating service according to tram operation model. First, we reviewed cases related to the evaluation of operating services in roads, buses, railways, and airways. And the evaluation criteria and the evaluation items are presented. This study is expected to help to secure and improve operational service in the operation phase of the tram that will be introduced in the future.
