The container terminals in Korea usually adopts both the bar code and the image recognition systems at the gate complex to capture necessary information on containers passing through the gate. With the rapid advancement of Information Technology(IT) these systems, however, seem to make the user not satisfied due to the inherent limitations such as the long process time taken, low rate of recognition etc., This paper, therefore, examines the adoption of Radio Frequency Identification (RFID) technology to container terminals, and tried to get some implication for the way to improve the productivity of the terminal. The results imply that some improvement in the gate and storage yard operation is feasible by the benefit of using the information of vehicles and containers collected in advance by RFID technology.

This paper proposed a new method in the implementation of ISDN (integrated services digital network) LAPD (link access procedure on the D-channel) and LAPB (link access procedure on the B-channel) protocols. The proposed method in this paper implement ISDW LAPD protocol through multi-tasking operating system and adopt a kernel part that is changed operating system to target board. The features of implemented system are (1) the para.llel processing of the events generated at each layer, as follows (2) the supporting necessary timers for the implementation of ISDW LAPD protocol from the kernel part by using software, (3) the recommanded SAP (Service Access Point) from CCITT was composed by using port function in the operating system. With the proposed method, the protocols of ISDH layerl, layer2 and layer3 (call control) were implemented by using the kernel part and related tests were carried out by connecting the ISDH terminal simulator to ISDN S-interface system using the ISDN LAPD protocol The results showed that ISDW S-interface terminals could be discriminated by TEI (Terminal Equipment Identifier) assignment in layer 2 (LAPD) and the message transmission of layer 3 was verified by establishing the multi-frame transmission and then through the path established by the LAPD protocol, a user data was tranfered and received on B-channel with LAPB protocol Thererfore, as new efficient ISDN S-interface environment was implemented in the thesis, it was verified that the implemented system can be utilized by connecting ISDW in the future to transfer a medical image data.

This study explores the incentive system in Korean ports to become a global logistics hub in Asia or to be competitive among Korean ports as a regional hub. First, we identified the types of port incentives in Korea and in overseas ports. We selected potential incentives applicable to Korean ports and compared whether they were meaningful, efficient, and effective in the short and long term. We selected IPA (Importance-performance Analysis) as an analytical method and surveyed users and experts. The results show that it is necessary and effective to provide incentives for new shipping companies, both export and import shippers, while setting criteria for reasonable incentives. Factors needed for improvement included simplifying and calculating the incentive request process, incentives for terminal operators, and new incentives, in addition to existing incentives. Policy-making organizations will also need to collect feedback on institutional improvements and raise awareness among users. Key factors for improvement include providing incentives for existing shipping companies. In particular, in order to actively manage systematic and efficient policies, incentive criteria for existing shipping companies need to be reconsidered.

Currently, ITs(Information Technologies} performances have been recognized as an essential tool for terminal operations. However, there have been little research that analyze level of ITs performance on port operation. Thus, the aim of this research is to analyze current level of ITs performance of major container terminals in Busan and Gwangyang. To achieve this objective, we developed HFP-based index that improve pervious indicator for evaluation of ITs performance. And then, level of ITs performance of four major container terminals were measured by the collected data through face to face interviews. Finally, through this analysis, some findings including weaknesses of ITs performance and implications were discussed.

The decreasing number of import and export containers is causing a problem with container circulation. In particular, this problem has reached a serious level in the Gyeongin area. Empty containers are accumulating in the Gyeongin container yard, where most of the returned containers are stored. In order to improve the empty container return problem at Gyeonhin, this study analyzes the actual situation and the empty container return process. A preference survey was conducted to suggest solutions from the perspective of users rather than shippers. A logistics company's data was analyzed to identify the inefficient cost structure in the Gyeongin area. The results show that the empty container return problem in Gyeongin is becoming more and more serious. To solve this problem, this paper proposes reestablishing functions at the Incheon Port, and securing a third new storage terminal in the Gyeongin area. Finally, an efficient empty container circulation system is presented. It will also be necessary to prepare laws and institutions to ensure these solutions.

Road transportation accounts for the largest share of cargo transport in Korea. Inland transportation is not only the beginning and completion point of container transportation, but it is also very complex and has many workers. The main job of container drivers, who play a key role in inland logistics, is to transport containers from ports and terminals to destinations. However, in addition to the main role, various container management obligations, such as cleaning containers and managing damaged containers during the transportation process, are implicitly transferred to container drivers. However, little research has been conducted on this issue. This study identified the working environment of container drivers and empirically analyzed the current status of container management responsibilities by drivers. Furthermore, it analyzed whether there was a difference in the degree of container management requirements by shipping company, terminal, and shipper. Differences in requirements for region(Busan, Kwangyang, Pohang) were analyzed, and improvement measures for the problem of transferring container management were also presented.

It is most desirable to build a crane training program in the same evvironment as the actual port, but it has problem such as time constraint and cost. To overcome these limitations, next-generation training programs based on AR/VR are receiving a lot of attention. In this paper, a prototype of a harbor crane training system based on virtual reality was designed and implemented. The system implemented in this paper consists of two elements: an Arduino-based IoT terminal and an HMD equipped with a Unity application program. The IoT terminal consists of 2 controllers, 2 toggle switches, and 8 button switches to process data generated according to the user's operation. The HMD uses Oculus Quest2 and is connected to the IoT terminal through wireless communication to provide user convenience. The training system implemented in this paper is expected to provide trainees with a training environment independent of time and place through virtual reality and to save time and money.

Korean ports have some problems in the aspect of quality & quantity in the bunkering process. Quality of bunker is assessed as more higher than competing ports. However, quality of bunkering procedure is assessed as lower. Especially, supply chain from loading of bunker to the bunker barge at oil terminal, transport it, and supply it to the ship has not been secured. Furthermore, aspect of quantity of bunker is more serious rather than that of quality of bunkering process. Disputes on the quantity of bunker between seller and buyer occur frequently, and residue & theft of bunker is also popularized issue and serious problem. Low bunkering fee is recognized as major reason of that problem, however, though low fee can be solved, it can not be necessary secured that problem could be solved, Therefore, this paper investigates and suggests the scheme to solve the quality problems of bunker supplying procedure, and develop solution toward advanced bunkering ports through removal of the quantity disputes. Concretely, this paper suggests introduction of quality system of bunker supply chain in the aspect of bunker supply procedure, and diversion from conventional sounding method to innovative Mass Flow Metering System in the aspect of bunker measuring. These two innovative solutions contribute to the removal and improvement of current structural problems in bunkering procedure.

The purpose of this study is to identify and evaluate the competitiveness of ports in ASEAN(Association of Southeast Asian Nations), which plays a leading role in basing the hub of international logistics strategies as a countermeasure in changes of international logistics environments. This region represents most severe competition among Mega hub ports in the world in terms of container cargo throughput at the onset of the 21 st century. The research method in this study accounted for overlapping between attributes, and introduced the HFP method that can perform mathematical operations. The scope of this study was strictly confined to the ports of ASEAN. which cover the top 100 of 350 container ports that were presented in Containerization International Yearbook 2002 with reference to container throughput. The results of this study show Singapore in the number one position. Even compared with major ports in Korea (after getting comparative ratings and applying the same data and evaluation structure), the number one position still goes to Singapore and then Busan(2) and Manila(2), followed by Port Klang(4), Tanjugn Priok(5), Tanjung Perak(6), Bangkok(7), Inchon(8), Laem Chabang(9) and Penang(9). In terms of the main contributions of this study, it is the first empirical study to apply the combined attributes of detailed and representative attributes into the advanced HFP model which was enhanced by the KJ method to evaluate the port competitiveness in ASEAN. Up-to-now, none have comprehensively conducted researches with sophisticated port methodology that has discussed a variety of changes in port development and terminal transfers of major shipping lines. Moreover, through the comparative evaluation between major ports in Korea and ASEAN, the presentation of comparative competitiveness for Korea ports is a great achievement in this study. In order to reinforce this study, it needs further compensative research, including cost factors which could not be applied to modeling the subject ports by lack of consistently qualified in ASEAN.
