Active RFID tags are currently used in harbor transportation; they are attached to cargo containers for sea transportation. They are designed to be able to be identified by RFID readers installed at ports in many countries. The international standard ISO/IEC 18047-7 regarding RFID conformance test methods suggests the use of air interface evaluation between an RFID reader and a tag. However, the test method suggested by the international standard is intended to detect a radio signal over only a very short period. Outcomes were uncertain, making it difficult to evaluate the system accurately. This paper proposes a new evaluation method by incorporating a 'self-running test mode' environment into the RFID tags in order to reduce the test time and increase testing accuracy. We found that the application of the suggested method to actual tags improves measurement time and uncertainty over that obtained using existing methods.

The ports have been confronted with rapid environmental changes. This means that it is imperative to enhance the competitiveness by resolving the chronic and difficult problems regarding Busan New Port. This paper, hence, suggests how to activate the hinterland of the New Port. The New Port was designed to become a leading logistics port in Northeast Asia and its economic ripple effect was expected to be much greater with the construction of New Port Hinterland. The government should also seek to supply the sufficient land as well as establish port clusters with various port-related industries, which enables the New Port to survive the forthcoming harsh environmental changes and meet the diverse demands. Those measures also enable the New Port to overcome the deterioration of the competitiveness and enjoy the economies of scale. The cluster-based hinterland policy framework is sure to be very efficient but should be complemented with infrastructure policies for the better policy-mix.

Because of rapid expansion of third party logistics, fierce competition in the transportation industry, and the diversification and globalization of transportation channels, an effective transportation planning by means of multimodal transport is badly needed. Accordingly, this study aims to suggest an optimal transport algorithm for the multimodal transport in the international logistics. As a solution for this problem, first of all, we have applied a pruning algorithm to simplify it, suggesting a heuristic algorithm for constrained shortest path problem to find out a feasible area with an effective time range, which has been applied to the Label Setting Algorithm, consequently leading to multiple Pareto optimal solutions. Also, in order to test the efficiency of the algorithm for constrained shortest path problem, this paper has applied it to the actual transportation path from Busan port of Korea to Rotterdam port of Netherlands.

최근의 통상환경중 "Logistics" 혁명을 통한 컨테이너 운송의 신속화, 인터넷혁명을 통한 전자상거래 활성화는 EDI, EC등을 통해 "Paperless trade"가 실현을 앞당기고 있다. 본 논고는 이러한 물류혁명과 인터넷 정보기술의 발달로 대두되는 문제중 기존의 종이서류로서의 운송서류를 전자식 운송서류로 대체하는데 따른 문제점과 이의 활성화 방안에 대해서 살펴보고자 한다. 인터넷 전자거래가 활성화되어지면 기존의 종이서류들은 전자메시지로 대체될 것으로 여겨진다. 이에 따라 전자계약서, 전자송장, 전자보험증권, 전자선하증권 등이 출현할 것이지만 이중 무엇보다도 전자식 운송서류중 유통성 운송서류의 전자화는 그간 전자화의 핵심부문으로 여겨서 상당한 중요성을 두어왔다. 현재 이용되는 유통성 운송서류는 그간 선하증권의 지연도착문제와 이에 따른 추가 경비의 소요, 또한 선하증권 발급에 따른 부대경비의 과다소비, 종이서류로서의 선하증권의 위조에 따른 사기문제 등에 제기되어 졌고 이에 따라 선취화물보상장 등의 현실적 대안이 제시되었지만 이 또한 여러 문제점을 야기시켜왔다. 전자식 운송서류는 이러한 문제점을 다소 해소할 수 있는 방안으로 알려져 왔다. 전자거래가 활성활 될 미래에는 운송서류의 전자화는 필연적으로 대두되게 될 것이고, 이러한 전자화에 있어 해상운송장의 사용은 바람직한 모델로 여겨지고 있다. 그렇지만 전매가 잦은 산업에 있어 해상운송장은 자체의 유통성의 미비로 인해 그 사용에 문제점이 있고, 실제 상관행에서 많은 이점을 가진 선하증권의 발행 욕구를 충족시켜 줄 수 있어야 할 것이다. 본 논고에서는 전자식 운송서류의 활성화 방안으로 첫째, 전자식 운송서류에 관한 법률정비가 필요할 것으로 여겨지며 둘째, 유통성 전자식 운송서류에 있어 관리기관의 안정성이 확보되어야 할 것으로 여겨지며 셋째, UCP에서 전자식 운송서류에 관한 조항이 삽입되어져야 할것으로 여겨지며 넷째, 여러 측면에서 우위성을 지닌 전자무역거래의 활성화는 점차적으로 운송서류의 전자화를 활성화시키는데 반드시 필요한 명제로 등장할 것으로 여겨진다.

As the current trend to the main index of the port competitiveness evaluation, the competitiveness index of the port service comes to more important than the part of expense, location and facility. To reform the bottleneck of port has an effect on improving port service competitiveness. Therefore, this study shows the importance of analyzing bottlenecks on logistics to improve port competitiveness. It collected recent questionnaire data which are the subject as the Custom Service, the Chamber of Commerce and Industry, the Trade Association about bottlenecks of port logistics for working out bottlenecks of domestic port logistics and it produced the order of priorities of bottlenecks by multiplying each output priorities and weights of each process in user of Incheon inner-outer port which is focused on container freight by analysis of priority and Analytic Hierarchy Process(AHP). Unlike existing studies, this study has important values. It presents the priority evaluation only focused on the container freight was produced by port users who are categorized into shipping company, terminal operation company and forwarder, car-ferry in Incheon inner-outer port and making a application of logistics process. It means internal and external competitiveness improvement plan can be presented more concretely and detailed than past competitiveness attributes such as location, facility, service and expense. If the analysis of port logistics bottlenecks which was focused on container freight is extended to the part of general cargo and sundries such as haul grain, car, scrap iron, those studies will be able to provide Incheon port users with useful information and a model of analyzing overall bottleneck of logistics in Incheon port.

Korea has achieved a remarkable growth by pursuing externally-oriented growth policy since 1960s. That is, we imported raw materials and spare parts, manufactured them into products and exported them, which led to successful economic development. Therefore, our marine business has played an important roles as one of key industries. The development of marine business has contributed to efficient distribution and cost reduction in addition to production of added value and creation of employment creation, which improved external competitive power. In spite of economic importance of marine business, national perception on it is in general low and its developmental conditions are considerably poor. Therefore, this study aims to speculate the effect of Port-related business on regional economy using regional input-output tables.

In maritime logistics, a large number of containers are transported to the destination through a port in the form of composite transportation such as ships, trucks, and railways. Logistics parties such as shipping companies and consignors prefer having the real-time information on the entry and exit of the logistics hubs of the freight. Particularly, a port is an important space that connects the maritime and inland areas. Hence, the interest about freight of the logistics party in port is high. This study describes tracking the location of freight by using GPS dynamically based on area type rather than point type. This presents dynamic information of location tracking when the freight enters, exits from, and passes through a certain port area. I suggest a real-time location of the container cargos tracking algorithm in port-entry, port-exit, and port inside using Active IP-RFID technology based on the location tracking algorithm of previous research.

The Port of Pusan, the largest port in Korea, handled 23% of total sea borne cargo movement, 14% of imported cargo, 58% of exported cargo and 95% of container cargo in 1989. Also the port of Pusan has been played a key role in handing container cargo throughout the last 10 years. The paper is aimed to survey the effect of sea borne cargo movement to urban transportation, that is, to find traffic volume arising by general/bulk cargoes through the port and to estimate vehicle rated of container tractor tailer on the roads between terminal including conventional piers and ODCY, and finally the following results are obtained. (1) AADV of truck to transport general/bulk cargoes are 6,322 units in 1989,and routes penetrate into the center of city and pass through the most of urban arterials. (2) In the container transport, if HVEF is adopted to 3 of tractor trailer, AVR in each transport freeway 13.7%. (3) IF HVEF is adopted to 6 of tractor trailer. AVR are as follows: BooDoo-Ro 44.1%, WooAm-Ro 39.3%, SooYoung-Ro 17.8%, Urban freeway 20.3%. Based upon these results, the following suggestions were drawn : o ODCY scattered around the city should be unified in a few groups to raise port productivity. o Rail service for inland container transportation should be escalated to relieve urban traffic congestion. o Coastal feeder service between terminal and hinterland should be studied to restrict the penetration of container tractor trailer into the central parts in the urban areas. o Exclusive freeway system for effective container transportation should be implemented to reduce urban traffic delay.

The purpose of this study is to show the clustering trend and compare empirical results, as well as to choose the clustering ports for 3 Korean ports (Busan, Incheon, and Gwangyang) by using meta-frontier DEA (Data Envelopment Analysis) and integer models on 38 Asian container ports over the period 2005-2014. The models consider 4 input variables (birth length, depth, total area, and number of cranes) and 1 output variable (container TEU). The main empirical results of the study are as follows. First, the meta-frontier DEA for Chinese seaports identifies as most efficient ports (in decreasing order) Shanghai, Hongkong, Ningbo, Qingdao, and Guangzhou, while efficient Korean seaports are Busan, Incheon, and Gwangyang. Second, the clustering results of the integer model show that the Busan port should cluster with Dubai, Hongkong, Shanghai, Guangzhou, Ningbo, Qingdao, Singapore, and Kaosiung, while Incheon and Gwangyang should cluster with Shahid Rajaee, Haifa, Khor Fakkan, Tanjung Perak, Osaka, Keelong, and Bangkok ports. Third, clustering through the integer model sharply increases the group efficiency of Incheon (401.84%) and Gwangyang (354.25%), but not that of the Busan port. Fourth, the efficiency ranking comparison between the two models before and after the clustering using the Wilcoxon signed-rank test is matched with the average level of group efficiency (57.88 %) and the technology gap ratio (80.93%). The policy implication of this study is that Korean port policy planners should employ meta-frontier DEA, as well as integer models when clustering is needed among Asian container ports for enhancing the efficiency. In addition Korean seaport managers and port authorities should introduce port development and management plans accounting for the reference and clustered seaports after careful analysis.

The purpose of this paper is to show the clustering trend and the comparison of empirical results and is to choose the clustering ports for 3 Korean ports(Busan, Incheon and Gwangyang Ports) by using the bootstrapped DEA(Data Envelopment Analysis) and game Cross-efficiency models for 38 Asian ports during the period 2003-2013 with 4 input variables(birth length, depth, total area, and number of cranes) and 1 output variable(container TEU). The main empirical results of this paper are as follows. First, bootstrapped DEA efficiency of SW and LT is 0.7660, 0.7341 respectively. Clustering results of the bootstrapped DEA analysis show that 3 Korean ports [ Busan (6.46%), Incheon (3.92%), and Gwangyang (2.78%)] can increase the efficiency in the SW model, but the LT model shows clustering values of -1.86%, -0.124%, and 2.11% for Busan, Gwangyang, and Incheon respectively. Second, the game cross-efficiency model suggests that Korean ports should be clustered with Hong Kong, Shanghi, Guangzhou, Ningbo, Port Klang, Singapore, Kaosiung, Keelong, and Bangkok ports. This clustering enhances the efficiency of Gwangyang by 0.131%, and decreases that of Busan by-1.08%, and that of Incheon by -0.009%. Third, the efficiency ranking comparison between the two models using the Wilcoxon Signed-rank Test was matched with the average level of SW (72.83 %) and LT (68.91%). The policy implication of this paper is that Korean port policy planners should introduce the bootstrapped DEA, and game cross-efficiency models when clustering is needed among Asian ports for enhancing the efficiency of inputs and outputs. Also, the results of SWOT(Strength, Weakness, Opportunity, and Threat) analysis among the clustering ports should be considered.
