Pusan is the largest fishing port in Korea, and deals with more than I million ton of fish catches annually, including catches of coastal and off-shore fisheries as well as those of deep-sea fishery. However, it hen had no fishing port facilities specialized fer deep-sea fishery since it started 30 years ago. Economic and physical losses resulting from this have teen enormous. Although fishing port facilities are a part of infra-structures built by Governments, the construction of them has been delayed due to financial difficulties of Central or local governments. To overcome this harsh situation to which deep-sea fishery cooperations faced, some cooperations have decided to construct fishing port facilities including fish-pier specialized for deep-sea fishery in Gamcheon port. The construction expenses of these facilities were financed by private funds to which they themselves jointly contributed. As a result, a fish-[pier, which has the capacity of serving one fishing vessel of 10, 000 ton or four of 5, 000 ton or four of 1, 000 ton at the same time, will be opened in here by 1994. The paper examines the master plan to revitalize the deep-sea fisheries industry in a deep depression with the opening of these physical facilities. The framwork of the plan is pursued in two different aspects, which are both hardware and software. In a hardware aspect, the plan in to develop Pusan into a city which is suitable for one of the best fishing ports in the world. That is, it is to develop the city into a place famous for sightseeing as well as the distribution and processing of fish-products centering around fish-piers. On the other hand, in a software aspet, it is regarding improvement of the distribution system of fish-products. One way to do that is to make up some deficiencies of the current system of a producers' joint sale. And the other is to establish an exchange of fish-products futures. Through these institutions, we could abrsorb speculative funds, which would otherwise be invested in speculation on fish-products, into productive investment opportunities, We believe that if the plan is realized, the deep-sea fishery in Korea will revive from a long-tasted depression and make progress to become one of the mai industries of Korea.

As port competitiveness is becoming more important in the global market environment RFID (Radio Frequency Identification) Is also becoming a crucial enabler In implement efficient visible, secure and productive ports. However there Is a lack of practical validated RFID technology acceptance cases in the port logistics industry until now, even though various related projects have been undertaken. In this study, we applied 13.56MHz passive RFID readers, tags, and their applications into existing bar-code based gate systems to improve the port logistics process, and we analyzed results of a pilot test in economic and non-economic perspectives. The main purpose of this study is to develop the RFID based automatic gate passing system in container terminals, and is to validate its economic and non-economic feasibility. In order to accomplish the purpose of this study, first, we examined previous researches on RFID technology acceptance in the port logistics industry, second, we Identified and analyzed the business process of existing gate systems in container terminals, third, we build RFID gate systems with 13.56Mhz tags, readers, and its middle-ware, finally we tested the system and its performance. The results were successful and showed the feasibility of the system in real container terminal gates. Economic and non-economic contribution was confirmed. Although the system has technological limitations with short range passive type, we clearly identified its potential capability and its economic validity in the field, which are the implications of this study.

The Korean government has been pursuing many supporting programs to enhance the competition of water transportation companies in recent years. To implement the policies effectively, which needs its monitering and evaluates about their business performance. The purpose of this study was to evaluate the business performance of water transportation company groups and determine the outranking between the groups using the Integrated Fuzzy AHP-PROMETHEE.. To achieve this purpose, first, the companies were classified into seven alternative company groups and the criteria for their evaluation was extracted Second, the weights of the criteria, by maritime and port expert survey, were calculated using the Fuzzy AHP. This paper, finally, determined the total priority orders of their company groups as the link Fuzzy PROMETHEE II with weights of the criteria and the local priority orders between them using the Fuzzy PROMETHEE I. In the proposal for this model, thus was collected four criteria such as growth ability, beneficial ability, technical ability, and productive ability. Through the result of this evaluation, the other marine transportation services group was determined as the highest outranking but the inland passenger & cargo transportation services group was lowest. Thus, the developing plan of the productive ability for the other marine transportation services group should be reviewed to continue its good performance, and all off the criteria for the inland passenger & cargo transportation services group to raise the performance should be reviewed.

The purpose of this paper is to measure the competition power of administration service in Korean Seaports by using the scores of customer satisfaction for administration service investigated yearly from 2000 to 2003 by Ministry of Maritime Affairs & Fisheries. And also, this paper shows the competition power of Korean seaports in terms of efficiency by using DEA(data envelopment analysis) method after measuring the change of productive efficiency scores subject to including and excluding the scores of customer satisfaction for administration service as output variable. The empirical main results of this paper are as follows: First, the efficiency scores of the Ports of Donghae, Gunsan, Jeju, Yeosu, Masan, and Pohang have worsened if the customer satisfaction score is excluded as output variable. Therefore these ports have been influenced by the score of customer satisfaction more positively. Second, the changes of the ranking order by measuring the average efficiency scores of each ports subject to including and excluding the scores of customer satisfaction for administration service as output variable are as follows: Busan(9-->7), Incheon(6-->6), Yeosu(1-->4), Gwangyang(4-->3), Masan (10-->9), Ulsan(5-->5), Donghae(8-->11), Gusan(12-->12), Mogpo(3-->2), Pohang(11-->10), Jeju(7-->8), Daesan(2-->1).

Apart from the DEA method, the traditional measuring systems of container terminal productivities generally bring to light the partial productive efficiencies, because they evaluate only the productivity of each individual facility. However, these methods do not play roles of the reasonable productivity measures to compare and evaluate the efficiencies of terminals to meet the requirement of terminal customers like as shipping lines, shippers, etc. with the cutthroat competition in container handling market. As the suppliers of service, the terminals struggle to cope with the needs of buyers' markets due to the lack of suitable criteria to measure the efficiencies. Therefore, this paper uses the simulation approach to reveal which strategies enhance the productivities through the container terminal analysis. An additional intent of this paper is to build the active strategies to present what the experimental indexes like as norm-time exactness ratio, norm-time excess ratio, etc. compare between terminals to measure the total productivities for the age of global supply chain management. However, the experimental productivity indexes presented in this paper require a validation of the exact usefulness, by consideration from all angles in the future, and a development to more reasonable measuring method/indexes for the container terminal productivities.

The Real Time Kinematic (RTK) technique is the most productive and accurate GPS positioning method today, as it can be determinate position within few centimeters instantly. This method is widely used for applications such as surveying, structure monitoring and machine guidance etc. In order to perform RTK processing for large scale systems (i.e. precise vehicle monitoring with many rovers), many expensive RTK receivers and same number of bidirectional communication units have to be installed to collect observation data communicate with the reference site and monitor its RTK solutions. Moreover, if applications require remote control or apply sensing instruments, we have to install computers at each rover. To limit expense and complexity of system management with a large number of rovers, we have developed server based RTK processing platform to share RTK function for all rovers. The system can be process many GPS stations with a single personal computer. we have also developed a specialized dual frequency GPS receiver unit without on-board RTK processing capability to reduce receiver cost in order to demonstrate the advantage of our server based RTK platform. This paper describes the concept of our server based RTK platform and specialized GPS receiver unit with existing applications in Japan.

In light of the significant increase in the quantities of goods transported and the development of the shipping industry, the frequency of usage of port structures has increased; yet, the government's budget for the shipping & port of SOC has been reduced. Port structures require systematically effective maintenance and management trends that address their growing frequency of usage. In order to construct a productive maintenance system, it is essential to develop deterioration models of port structures that consider various characteristics, such as location, type, use, constructed level, and state of maintenance. Processes for developing such deterioration models include examining factors that cause the structures to deteriorate, collecting data on deteriorating structures, and deciding methods of estimation. The techniques used for developing the deterioration models are multiple regression analysis and Markov chain theory. Multiple regression analysis can reflect changes over time and Markov chain theory can apply status changes based on a probabilistic method. Along with these processes, the deterioration models of open-type and gravity-type wharfs were suggested.
