Pusan the principal port of South Korea, has opened its door since 1876. Currently, the four-stage port construction project is under way to handle ever-growing marine transportation volume. While the port unloading capabilities are increasing the infrastructure to deal with all the transportation volume failed to catch up with them. Accordingly the city had to suffer from worst traffic congestion on due to the increasing container traffic volume causing logistical costs to rise. This study was designed to inspect the enforcement of infrastructure construction plan and suggest systematical and effective ways to improve the plan. The study focused on :\circled1The decision-making procedure, \circled2Financial resource for the plan, \circled3Effectiveness of the project enforcement, and \circled4Who will be in charge of the project. As a result from the study, these followings were suggested to improve the plan. First, Pusan Port Infrastructure consisting of (Inter-city Free way, Belt Highway and Outer Highway) should be immediately legally-regulation project. Second, the method to finance the project should be deter-mined and investment consultation among the central government the city government and private sector should be also made. Measures to make the central government budget allocation for the project mandatory should be discussed. Third, Effectiveness of the project can be doubled by gradually or partialyl opening the routes based on long-term or short-term operating plans. Fourth, The organizer of the project should be appointed, or a special task-force team in charge of the plan can be formed.

The flag State is primarily responsible for implementing international maritime conventions(IMO conventions) and national laws and other standards as far as its own vessels are concerned, on the other hand the port State exercise its rights for the safety and marine environment under international law especially UNCLOS within port and territorial sea. In particular, the port State may take appropriate measures including detention of ships identified as sub-standard vessels which are considered as port State's supplementary role aiming for implementing international and national and regulations. But in the course of implementing port state control, international disputes may happen between port state, coastal state and flag state in spite of making all possible efforts to avoid these disputes. This paper aims to consider legal grounds on port state control(PSC) in international conventions and national laws concerned and deals with contradictions between international and national law arising from exercising PSC by port state control officers(PSCOs).

Rapid change in the technological environment of marine transportation and the development of the ocean shipping industry have fostered a revolution in the port system. This in turn has caused major changes in the function and use of port in Korea. Aside from this, Mokpo Port, however continues to decline, because the existing port facilities and related subsystem are already obsolete with no chance of regaining operational effectiveness and treatment for proper implementation. Although a few studies have been done on the Mokpo Port, has not been found, any reseach for the analytical approach to the transportation system of it. This paper aims to make an extensive analysis of the physical distribution system in Mokpo Port focusing on the coordination of subsystems such as navigational aids system. The base of introduced simulation tool here is the queueing theory. The overall findings are as follows: 1. Among those vessels called at Mokpo Port in 1994, 556 ships(2,736,669 G/T) are oceangoing while 8155 ships(2,587,217 G/T) are domestic. The average size of oceangoing vessels is 4,922,1 G/T, and the domestic is 317,8 G/T. The average arrival interval and service time of the domestic vessels are 6.0 hours and 24.1 hours respectively marking the berth occupation rate over 100%. Those for oceangoing vessels are 34.5 hours, 120.0 hours and 37.2%. In order to maintainin the berth occupation rate to 70% the capacity considering the 1994 of domestic piers must be extended to 145% and oceangoing vessels must be increased to 165%. 2. The capacity of approaching channel is enough to handle the total traffic volume of 3. Tugs are sufficiently being provided to handle all ships requiring their services 4. The capacity of storage and inland transportation systems are sufficient to handle the throughput and the yard stroage utilization rate of No.1 - No.5 is 4.5% and No.6 is 30% of 1993's. 5. The utilization rate of LLC(Level Looping Crane) and PNT(PNeumaTic) are 2.7% and 18.8%, respectively.

As dual port RAMs are widely used in the various applications, the need for an efficient algorithm to diagnose faults in dual port RAMs is increased. In this paper we propose an efficient algorithm that can diagnose all kinds of faults in dual port RAMs. In addition, the new algorithm can distinguish various fault models and locate the position related to each fault. Using the new algorithm, fault diagnosis for dual port RAMs can be performed efficiently and the performance evaluation with previous approaches proves the efficiency of the new algorithm.

In order to respond dynamic changes in the global distribution system, the City of Pyeongtaek hope to expand port facilities and its hinterlands. In specific, it plans to designate these areas as free economic zones(FEZ), synthesizing the whole procedures from the development proposals to the operation and management. This paper examines the proposed urban development strategies focused on Pyeongtaek port which still reveals critical weakness as a gateway port backed up by the Seoul Metropolitan Areas. In order to enhance the global competitiveness of Pyeongtaek port, theoretically it depends on Geo Coyle's ACTIFELD methods. In addition to the traditional quantitative data, Coyle's ACTIFELD methods emphasize qualitative approaches, all of which would facilitate structural and systemic analyses of complex social phenomena. Applying ACTIFELD methods, this paper proposes that the City of Pyeongtaek should focus on three alternatives. That is, Pyeongtaek's policy priority should be given to ts he port city based on the key concepts of Supply Chain Management(SCM), Co-opetition supporting city, and waterfront-initiated urban development.

In this paper, a method of inputting one analog input and two digital switch inputs by using one analog port of microcontroller embedded in IoT device was proposed. In this method, the upper limit and the lower limit of the input voltage range of the analog input port are determined, and the analog input voltage is input to this interval. The digital switches are configured to exceed the boundaries of the upper and lower limits, respectively. To verify the performance of the proposed method, an experimental circuit was constructed and tested using a microcontroller. As a result, all three inputs can be sensed using a single analog port, thus confirming that the three required input ports are reduced to one input port, ie, 33%.

To develop the port productivity and effictiveness, the introduction of the On Dock Operating System in Pusan Container Terminals has to be considered and the present Off Dock CY be closed step by step. This work aims to evaluate the needed CY area in Pusan Port under the On Dock Operating System. This researching flow is as follows. Firstly, estimate total sea-borne container cargo volumes in Korea and distribute them to all container terminals according to the past trends and the planned port development. Secondly, estimate the average period and the average tiers stored at On Dock CY in case of On Dock Operating System. Thirdly caculate the needed CY Area to handle the distributed container cargo volume under the On Dock Operating System. Finally, the following results are obtained. (1) In 1998, opening the Gamman Terminal, 827 thousands cubic meters are insufficient. (2) In $2001\sim2004$, the insufficiency of needed CY Area will be maximized and estimated to be 936 thousands cubic meters in 2001. (3) In $2005\sim2011$, opening the Gadu Terminal, the insufficiency of needed CY Area will be decreased and estimated to be 240 thousands cubic meters in 2011.

Nowaday all the countries of the world have studied the various problems caused in operating their own ports efficiently. Ship delay in the port is attributal to the inefficient operation in the navigation aids, the cargo handling, the storage and transfer facilities, and to the inefficient allocation of gangs or to a bad service for ships. Among these elements the allocation of gangs is the predominating factor in minimizing ship's turn round time. At present, in the case of Pusan Port. the labour union and stevedoring companies allocate gangs in every hatches of ships by a rule of thumb, just placing emphasis on minimizing ship's turn round time, without applying the principle of allocation during the cargo handling. Owing to this the efficiency of the cargo handling could not be expected to be maximized and this unsystematic operation result in supplying human resources of much unnecessary surplus gangs. Therefore in this paper the optimal size and allocation of gangs for minimizing the ship's turn round time is studied and formularized. For the determination of the priority for allocation the evaluation function, namely $F=PHi^{n}{\times}(W+H)$, can be obtained; where, PHI : Principal Hatch Index W : Total Cargo Weight represented in Gang-Shifts H : Total Number of Ship's hatches and also for the optimal size of gangs the average number of gang allocated per shift (Ng), namely Ng=W/PHI, is used. The proposed algorithm is applied to Pusan Port and its validity is verified.

It is no exaggeration to say that today's world economy is dependent on international trade, which is the result of inter-state transactions. As the vast majority of international goods transport is transported by international shipping, interest in the seaborne transport field is natural in international and trade studies. In particular, in the case of international shipping, as it is the basis of typical international transportation, changes in international shipping due to the innovation of technology may have an effect on international trade norms. In this study, as a result of evaluating port preference in a hypothetical scenario by using the Design of Experiments method, bunkering as well as port service, which is traditionally important, was identified as a major competitive factor of future ports. It has been revealed that, above all, the port to respond to the future is the continued importance of port services and the supply of ship fuel. Therefore, port authorities are providing implications that LNG bunkering infrastructure suitable for international environmental regulations is important.
