The Principle objective of this paper is to introduce a systematic approach to identifying similar container ports in Asia. For this, it analyses data on port facilities, port facility availability, port service level total container throughput, and economic index, by using Multidimentional Scaling (MDS) method. Based on the analysis it identifies five groupings of similar container ports in Asia within which Port comparison can be justifiably made, evaluates a present position of five groupings on the basis of factors used to compare container ports in Asia ; and finally proposes policy implications for operation efficiency of Pusan container port in comparison with Kaohsiung Port. The major implication is that both the Kaosuing and the Pusan port have to strengthen port facility to attract more traffic, and particularly, Pusan Port has to reinforce the number of berth, total length of berth. and yard areas.

After 1970-80's rapid economic and urban development, nowadays the old downtown suffers from the deterioration of physical environment, outflow of its function and cavitation of population. And this phenomenon makes urban regeneration as a new paradigm in urban development. This is the case of Myeongdong area (Jungang-dong, Monsung-dong), old downtown of Cheonan around rail station, in the same way. City government has tried many regeneration/ redevelopment projects on this area but all failed due to lack of feasibility. This study intends to suggest new viable strategic regeneration scheme of this area through research and analysis of TOD development, existing condition and problems. As a result, the area needs to be considered as a node that links bus terminal complex and central market place with walkable street. For regeneration of this area, a strategic development scheme of this area is suggested deploying private capital invested rail station, underground shopping mall, transfer center, culture complex and nature park with Myeongdong street mall.

Java Card has gained genera1 acceptance with standard for smart card and (U)SIM technology, and it is in distinction from native card by its post-issuance of an application and independence from hardware platforms. However, a main weak point of Java Card is its low execution speed caused by the hardware limitation and Java programming language itself. In this paper, we propose a new Java Card Installer to improve the download speed during the post-issuance of an application by resolving symbolic references to physical references in HAM. Our Resolution_In_RAM is based on the improved new RAM writing is 100,000 times faster than EEPROM writing and PageBuffer that is operated as block mode, rather than cell mode is used to write to EEPROM. Consequently, the total number of EEPROM writing are reduced 37%, and the times of downloading are reduced over 30% by using the Resolution_In_RAM-based Java Card Installer.

In this paper, we describes the design and implementation of real-time management system for efficient operation via monitoring and control of MCC(Motor Control Center). The real-tine management system can be divided hardware(MCC panel) and software(management program). First, hardware is divided into load attaching motor and MCC components for working together control and data network. Second, software(management system) are consisted of communication interface, environment setting, data processing modules. The produced and implemented reduction model of MCC panel is pretested using m-PRO, iM-PRO devices, and HyperTerminal. For field test, MCC panel is tested by RS-232C/485, communication procedure in management system is certified by transmitting and receiving message using control command. By the experimental results, the implemented real-time management system can be used to operate MCC system.

This article describes advanced clover algorithm for effective loading and unloading of containers using stackers position data in a yard. The job scheduling must rely on job assign of stackers and position data processing to dynamically allocate stackers, and maintain multiple job processing, all based on task requirements. A stacker tracking using GPS and GIS is an essential capability and is used as yard loading and unloading process improvement for yard management. After estimating position of stackers in a yard the raper describes advanced clover algorithm and other techniques for monitoring loading and unloading of individual containers as well as combinatorial stacker load balancing problems such as estimating load of each stackers. Results from simulations and experimental implementations have demonstrated that the suggested approaches are efficient in stacker management.

This paper is concerned with departure passengers' dwell time analysis using real system data. Previous researches emphasize the importance of dwell time analysis from perspective of airport terminal planning and non-aeronautical revenue. However, short-term airport operation using passengers' dwell time is considered impossible due to absence of passengers' behavior data. Recently, in accordance with the wave of smart airport, world leading airports are systematically collecting passenger data. So there is high possibility of analyzing passengers' dwell time with the data stacked in the airport database. We conducted dwell time analysis using data from Incheon Int'l airport. In order to handle passenger data, we adapted clustering algorithm which is one of data mining techniques. As a clustering result, passengers are divided into 3 clusters. One is the cluster for passengers whose dwell time is relatively short and who tend to spend longer time in the airside. Another is the cluster for passengers who have near 3 hours dwell time. The other is the cluster for passengers whose total dwell time is extremely long.

The purpose of this study is to activate Korea's coastal passenger shipping by improvement of the deterrent factors on the basis of field data collected in order to help stimulate it and enhance its competitiveness. As the representative model of this study, the "P" car-ferry liner was chosen, whereby various deterrent factors were observed in the course of the SWOT analysis and through the questionnaires. The major deterrent factors in summary were inflexible government regulations for additional ship operation, disadvantages of taxes policy, port facility shortages, non-allowing of ship's night operation, complicated and inflexible ship's operation controls by the concerned authorities, unreasonable divisions of steaming areas, and existences of obstacles on the ship's running routes, etc. which considered all are important to activate the liners.

Most metropolitan shippers (MS) have used trans pacific route (TPR) or Asia-Europe route (AEP) through Busan port (BP). If Incheon new port (INP) sets up the deep water-depths under -16m, however, there might be a change in MS's port choice behavior (PCB). In this respect, the aim of this paper is to estimate an INP's allotment rate for metropolitan cargo using Logit Model (LM) considering changing global shipping and port environment. This paper reviews previous studies related to shippers' PCB then sets up the utility function (UF) including the dummied dependent variable which is comprised of BP and INP, and some independent variables such as the frequency of liner shipping route (TPR), inland transportation fare, and the rate of container terminal service. As a result of LM analysis, BP has 0.6618 and INP has 0,3382.

The cruise industry is a future-oriented convergence industry based on tourism and shipping, and has attracted great attention not only in the global market but also in Korea. The rapid growth of Asian cruise population, especially in China, has had a considerable impact on both the global market as well as the Korean market. With the recent THAAD problem, the need for diversification of the market has been raised as the entry of cruise tourists from China has been greatly reduced. It is also time for a more systematic and comprehensive development strategy ahead of the opening of the new cruise terminal. This study draws out the problems based on the interviews with experts such as prefectures, travel agencies, and related organizations, as well as analyzing literature on domestic and overseas government plans, policy reports, and research data. Then, the SWOT analysis is used to develop the development strategy and explore the policy support direction. The research scope can be extended to sustainable development model through wider linkage of mid to long term strategy and policy.

This paper assessed the impacts of the specification of the yard, handling equipment, and operation approaches on the expected number of re-handles during the loading operation for empty containers. When the various types of empty containers from multiple shipping liners are placed in separate spaces from each other, then the storage space cannot be fully utilized. So as to increase the utilization of the storage space, empty containers from multiple vessel liners are stored together incurring additional re-handles during the loading operation. Several formulas are derived for the estimation of the expected number of handles, including re-handles, for empty container retrieval from a bay. Transfer cranes and top handlers are utilized as handling equipment and various retrieval strategies are examined. Numerical analysis was conducted to assess the effects of various designs and operational parameters of the container stacking yard on the expected number of handles.
