Recently, The government of Korea declared to develop RFID(Radio Frequency IDentification) as one of key strategic technology to perform U-Government using Ubiquitous technology. But, most of the related technologies for RFID are mainly focused on the inlaned application excepting marine applications. The last target of this study is to implement new Marine RFID(M-RFID) that can cover all of EEZ areas as large five times as inland volume. In this paper, as a basic study for the M-RFID, we carried out an establishing the concept design of M-RFID, developing the construction method of M-RFID and, extending the idea of M-RFID. As studying results, it is known that the M-RFID can be use in many practical areas such as the protection of EEZ area and aqua culture, the safety of fisher man, the disaster control for inlander and, fisheries ligistics with real-time.

This paper presents the educational methodology shipboard training methods of Maritime Colleges in U.S.A. and the fields of engagement in business of the graduates from them. There are two Maritime Academies, i.e. U.S. Merchant Marine Academy (USMMA) and U.S. Coast Guard Academy, which are supported by federal government and six Maritime Colleges operated by each State. Maritime Administration (MARAD) in the Department of Transportation (DOT) supports the training of merchant marine officers and crew members with a focus on safety in U.S. waterborne commerce. The shipboard training methods are not unique, but have various process. One is continuous sea term training onboard during sophomore (100 days) and junior year (200 days) in case of USMMA, the other is summer sea term training onboard every three months during freshman, sophomore and junior years in case of SUNY Maritime College. They offer also one month ship simulator training ashore. The employment status for the 1999 year graduates from USMMA shows 43 percent in the field of maritime afloat, 34 percent of maritime ashore, 22 percent of active duty military and 1 percent of others.

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, quay handling and transfer system, storage system and inland transport 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, 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% year called. 2. The capacity of approaching channel is enough to handle the total traffic volume. 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 $\cdots$ No.5 is 4.5% and No.6 1S 30% of 1993's. 5. The utilization rate of LLc(Level Looping Crane) and PNT(PNeumaTic) are 2.7% and 18.8%, respectively. Practical solution and proposal for improvement of Transportation System in Mokpo Port are as follows; 1. To avoid the congestion in domestic pier introduction of a new port operation system is necessary allowing the domestic vessel to use the oceangoing pier. 2. To establish the port management information system to improve the efficiency of port operation. 3. To build a new storage system for high valued cargos including modernization of the present storage and handling system. 4. To insure the safety of navigation in approaching channel, The Vessel Traffic System including separation scheme is introduced. 5. To interest enormously on public relation to ship owner's association, shippers and consignees by showing that they can save cost and ship turnaround time in order to promote the call to Mokpo Port. At last, to be strategically change the function of Mokpo Port to the Leisure, Fishing & Ferry as well as Maritime port.

In order to propose basic references for the policy making of fishing vessel fishery by Jeju Special Self-Governing Province, we have obtained the basic productivity through analyzing operating days and catches of 16 sample fishing vessels registered in Aewol port, the north of Jeju island in the year of 2011. In addition, to compare with the basic productivity of southern sea area in the Jeju island, that of 7 sample fishing vessels registered in Kangjung port was used. Around Aewol port, average operating days during the main catch period from July to October were over 15 days a month. A average daily catch of fishing vessels was minimum 21.0 kg in May and reached to maximum 54.5 kg in December, showing U-shaped catch pattern through the year. The trend formula of the average daily productivity (y) depending on a tonnage (x) of fishing vessels around Aewol port was described by the equation, y = 18.867 ln(x) + 11.001, and that around Kangjung port in the year of 2009 was understood to be y = 23.271 ln(x) + 25.715. As a result, it seemed that the productivity of fishing vessels around Kangjung port, operating in the southern sea area of Jeju Island, was much greater than that of fishing vessels around Aewol port in the northern sea area of Jeju Island. Especially, that of fishing vessels less than 10 tons was 35-40% more.

This paper outlines a plan to promote South Jeonnam region's logistics capability in connection with the regional logistics bases such as Gwangyang Port, Jangseong Integrated Freight Terminal, Mokpo Port and Muan International Airport. The capability of regional innovation bodies, and industrial innovation generally, needs to be improved by establishing a systematic regional innovation plan. Smaller import and export logistics bases, presently scattered in downtown Gwangju and its suburban area, need to be integrated as soon as possible, in advance of the completion of a traffic network connecting all of the triangle logistics bases. Moreover, plans to develop Muan International Airport to the status of a hub airport need to be established, and its function as an air freight terminal should be strengthened. Gwangyang Port and Mokpo Port should be developed as Korea's key harbors with international logistics bases the two ports, presently conducting simple cargo work, should be transformed into general logistics ports conducting logistics, assembling, trading, and international business by developing their surrounding areas.

Today the role of Vessel Traffic Service(VTS) is increasing due to the function to preserve the safety of marine traffic and harbour, improve the efficiency of harbour, protect the marine environment. However, Vessel Traffic Service(VTS) lacks the international and domestic legal basis. For this reason it is hard to fulfill the positive and systemic operation of Vessel Traffic Service(VTS). It is essential to establish a domestic legal basis upon which to perform function and role of Vessel Traffic Service(VTS) fully. The purpose of this study is to propose the directing point for the adequate regulation of vessels to participate in Vessel Traffic Service(VTS) by doing a comparative analysis between domestic regulations and other countries's regulations.

More accurate forecasting of port cargo in the global long-term recession is critical for the implementation of port policy. In this study, the Busan Port container volume (export cargo and transshipment cargo) was estimated using the Vector Autoregressive (VAR) model and the vector error correction (VEC) model considering the causal relationship between the economic scale (GDP) of Korea, China, and the U.S. as well as ARIMA, a single volume model. The measurement data was the monthly volume of container shipments at the Busan port J anuary 2014-August 2019. According to the analysis, the time series of import and export volume was estimated by VAR because it was relatively stable, and transshipment cargo was non-stationary, but it has cointegration relationship (long-term equilibrium) with economic scale, interest rate, and economic fluctuation, so estimated by the VEC model. The estimation results show that ARIMA is superior in the stationary time-series data (local cargo) and transshipment cargo with a trend are more predictable in estimating by the multivariate model, the VEC model. Import-export cargo, in particular, is closely related to the size of our country's economy, and transshipment cargo is closely related to the size of the Chinese and American economies. It also suggests a strategy to increase transshipment cargo as the size of China's economy appears to be closer than that of the U.S.

Recently several researches of high speed container ship and loading system are mainly accomplished in U.S.A. and Japan. Its shipping service is not realized but it is realized in near future. To effective use of the feature and efficiency of them, quay, loading/unloading. yard operation system, port management system and connection transport system must be well integrated and operated. Specially, loading /unloading speed of container crane is important for making effective use of them. To speed up loading/unloading system, RO-RO and LO-LO methods that are mostly exclusive system are studied on the container crane with special structure and mechanism to handle individual container or bundle of containers. In this paper these methods are shown. When new high speed loading system of container is desighed, the realistic constrains must be considered.

Within the framework of the modified factorization method, we solve the $Schr{\ddot{o}}dinger$ equation with the modified Yukawa potential. The energy spectrum is obtained using the Pekeris approximation scheme for the centrifugal term. The thermodynamic properties, including the vibrational partition function, vibrational mean energy, vibrational mean free energy, vibrational specific heat capacity and vibrational entropy, are calculated. As a special case, we compare our result with that work of Dong [Int. J. Quant. Chem. 107, 366 (2007)] and find good agreement.
