Cai-go management facility of harbor are required an expansion due to increase of cargo quantity. Design technology of Yard AGV call be possible to deal many cargo rapidly and accurately. So it is produced a profit about cal-go management. This study is presented optimum of suspension parameter for design technology Yard AGV. Model I, II are modeled about Initial of container weight, height. When the maximum stroke of suspension is 0.26m, optimum is achieved to reduce the reaction force at the minimum. Also, the reaction force is study to become stability in I second. A change of spring constant and coefficient of damper make change the reaction force and minimum reaction force appear in optimum value. All modeling and analysis are used combination. contact element of Ansys program.

현재 전 세계 체약국들은 증가하는 항공수요를 충족하고 공역의 이용 효율성 및 항공기 운항의 경제성 등을 제고하기 위해 국제민간항공기구(ICAO)에서 전략적으로 개발하고 채택한 차세대항법시스템(New CNS/ATM, PBN 등)의 각종 항법 및 통신 어플리케이션 등을 도입 적용하고 있다. 이 가운데 AIDC(ATS inter-facility Data Communication)는 조종사와 관제사간 반복적으로 이루어지는 교신(Verbal Communication)사항을 포맷화한 후 데이터로 송출하여 조종사와 관제사 양측 모두의 업무로드를 감소시키며 주파수 점유 시간을 단축시켜 주파수 활용도를 크게 증가시키고 있다. 또한, 비영어권 국가와의 음성 통신시 부정확한 발음 등으로 야기 될 수 있는 인적요인(Human Factor)을 사전 제거하는 등 많은 혜택(Benefits)을 제공하고 있다. 비록 이번 연구에서 항공 AIDC의 모든 요소가 VTS에 1:1 적용 되지는 않지만 AIDC의 주요 요소(TOC, AOC 등)와 우리 해상교통 실정에 맞는 응용 요소(RTOC)를 추가하여 주파수와 관제센터는 다르지만 관제구역이 서로 인접해 있는 구역에 적용시켜 잠재적 위험요소를 사전에 예방하고, 궁극적으로 Service provider로서 이용자 중심의 VTS를 설계하고자 한다.

This study is intended to apply universal design concept and guideline to the boarding facilities of pleasure boat. In order to fulfill the purpose of the study a site survey at Suyoung Marina has been carried out. Out of the survey some problems are picked up for each part of access and pier facility, boarding platform and inside door. Practical measures for improving the situation are suggested.

This paper focuses on the frozen storage warehouse located in Busan area, and it is because Busan is the most dense area in Korea. Busan is a port city, and almost all of the frozen refrigerated cargo imported from abroad is concentrated. By taking advantage of its strength as a fishery industry as well as importing, Busan is building the largest international fishery logistics base in Northeast Asia and plays an important role in the export of refrigerated cargo is. Therefore, although the freezing and chilling facilities seem to be developed with the latest technology, the reality is not so. Most of them are functioning as a warehouse, that is, a storage function, and a considerable number of refrigerated warehouses are in a state of aging. Therefore, in this paper, the facility and function restructuring of the freezing storage warehouse have been set as a solution task, and the introduction of the cold chain system containing the latest smart technology has been proposed as a solution.

A Teleport is an integrated facility that provides its users with fast, convenient access to advanced telecommunicatoins by satellites, fiberobtics, microwave and other networks. A teleport town is an urban sub-center equipped with teleport and other telecommunication infra-facilities. This study is based on the explicit disclimination between these two related concepts. In this paper we classify various types of teleport town with respect to the specific conditions and situation in Korea. The teleport town which will be developed in Korea should be fitted into the balanced regional structure to boost up the effects of urban or regional development plan. Three models of teleport town(large scale, middle scale, small scale) are proposed on the basis of the classified types of teleport town.

China, a leader of regional economies in North-East Asia, helps to integrate a single shipping market and affects diversely main ports in the region through affecting the flows of container transshipment, strategies of shipping companies for port calling and shipping networks. This study examines competition and cooperation among the hub ports in the region through studying examples of the three Chinese hub ports -Hong Kong, Shanghai, and Tianjin- and concludes some implications of status change of hub ports in the region after scrutinising development process of the Chinese main hub ports and the historic interaction of port development among these ports. The characteristics of growth pattern of three ports are as follows. The port of Hong Kong constructs step by step the container facilities in accordance with demand growth and prefers stabilisation of operation and management through scale enlargement of port facilities. Even though demand grows continually, the port of Shanghai continued its defensive attitude towards facility expansion till the 1990s and has tried to get economies of scale in enlargement of port facilities. The port of Tianjin, similarly as the two other ports, expands serially its facilities and utilizes the capacity concentration and functional specialisation of facilities. The analysis of panel data and panel regression of three hub ports implicates that each port has its own specific demand and shows that the interaction of container handling among three ports was weak in 1980s and has become stricter and stronger since 1990.

Nowadays the trade volume between Korea and China is rapidly increasing. With the current trend in mind, this study aims to seek strategic plans for increasing cooperation between Korean and Chinese logistics industries. The plans are especially centered around port regions, since ports are responsible for most of the trade volume between the two nations. As for the method, a case study was carried out in capital area ports in Korea and Shandong Province port regions of Bohai Economic Rim in China to address the problems and propose strategic plans to promote cooperation between the two nation's logistics industries, specifically with port regions as the center. The results showed that in increasing cooperation between Korean and Chinese logistics industries, the most important factor is for the two governments to put effort in solving the problems arising in port areas. Moreover, Korean government should strengthen its support to Korean companies in Chinese port areas as well as exert effort in multilateral ways such as system improvement and facility investment for capital area ports so as to gain competitive edge against China. This study contributes to the existing literature in that it applies suggested cooperative strategies for Korea-China logistics industry from previous studies to port regions as the focus, and it also sheds new light on institutions located in port areas through in-depth interview.

The quantity of container transportation of the world harbors is constantly increasing by 8.8％ per year until 2011. present port facilities will not satisfy it. So facility expansion is necessary. Because the processing cost in the harbor becomes to 30％ of total transportation expense, major ports in the world are making an effort in the automation facilities to solve the problems of higher labor costs and insufficient labor and to maximize the efficiency of the work and use of the land. Especially, the automation of the gate, which is the place of cargo's appearance and disappearance, the node which creates the information. is now rising as the important issue. In this study suggests more efficient design for port gate automation.
