항만 내에서 선박 체류 시간을 단축시켜 선박의 운항 회전율 극대화 및 컨테이너 처리 현황 정보를 실시간으로 제공하는 동의 선사에 대한 서비스 제공은 항만 간의 경쟁에서 우위를 정하기 위해 매우 중요해지고 있다. 이러한 변화에 대응한 u-Port(또는 smart-Port)는 항만을 통하는 모든 수출입 물류에 대해 u-IT 기술을 기반으로 실시간 경로 추적 등이 가능한 항이다. RFID, RTLS 및 USN 기술을 통한 u-Port 구축 노력과 최근에는 스마트폰, GPS, WiFi, Wibro, 3G, 유무선 통합 등의 기술을 활용한 smart-Port 구축에 대해 논의되고 있다. 이들 첨단항만들은 물류 프로세스의 리드타임단축, 실시간 컨테이너 추적, 무인자동화 등을 가능하게 하여 항만의 시간적 경제적 효율성을 대폭 향상시킬 것이다.

This paper measures the economic impacts of the U.S. port investment strategies coping with the Panama Canal expansion. Using secondary import data, negative and positive estimates of the impacts were presented in this study. Reduced port activities into the West Coast Customs Districts negatively affect transportation and warehousing industries, among other effects. Still, they have simultaneous positive effects in other states from increased imports resulting from modal shifts and changes in the entry port located in the South and East coasts. This study applied the supply-driven National Interstate Economic Model that measures all interstate trade among the U.S. states to divert foreign imports from 15 Pacific Rim countries. For this purpose, the following assumption was adopted: larger ships using the canal will lead to a redirection of seaborne trade among U.S. (and other) ports and result in secondary effects, e.g., using different freight modes and regional growth spillovers. This study also accounted for the entry point change and significant port investments for foreign trade under alternative scenarios. The choice of ports for international trade depends on decisions about how to minimize multimodal delivery costs. The total direct reduction of transportation and warehousing activities associated with foreign imports in the West Coast ports was estimated at $3.3 billion, leading to total negative effects of $5.8 billion. Total positive impacts from the shift of transportation modes with the choice of an entry port and new warehousing activities for foreign imports in the selected 12 states varied. As expected, states that involved an entry port had the most prominent benefits, but Texas, New York, and New Jersey may be benefited through all the port enhancement projects in the U.S. Also, except for Transportation and Postal, and Warehousing industries, Construction is another dominant positive affected industry of the Canal expansion in the U.S.

Due to increased competition in supply side to reduce operational costs, port professionals have experienced extreme pressure, which demanded academicians to develop the model for efficient port operations from the industry perspective. Among many ports in the world, U.S. ports are our primary interest to analyze in our study for its high volume of cargoes transacted in the U.S. ports. We primarily employed DEA (Data Envelopment Analysis) technique to research the productivity of U.S. ports and applied the algorithm of double bootstrapped DEA proposed by Simar & Wilson (2007) to further investigate the driving forces of the performance of U.S. port operations. The external variables employed in our study comprise onDock Rail, Channel Depth, Location, Area, Acres, ForeignCargoRatio, and TEUChange, out of which onDock Rail, Acres, ForeignCargoRatio, and TEUChange were significant. In order to evaluate the effects of methodology selection, we conducted the same analysis applying the Censored model (Tobit) and contrasted the outcomes drawn from the two different techniques. Based on the findings from this work we proposed managerial implications and concluded.

As the ubiquitous environment is created, the latest ports introduce U-Port services in managing ports generally and embody container's location identification system, port terminal management system, and advanced information exchange system etc. In particular, the location identification system for freight cars and containers provide in real time the information on the location and condition for them, and enables them to cope with an efficient vehicle operation management and its related problems immediately. However, such a system is insufficient in effectively handling with the troubles in a large-scale port including freight car's disorderly driving, parking, stop, theft, damage, accident, trespassing and controlling. In order to solve these problems, this study structures the vehicle positioning system and the image verification system unsing high resolution image compression and AVE/H.264 store and transmission technology, able to mark and identify the vehicle location on the digital map while a freight car has stayed in a port since the entry of an automatic gate, or able to identify the place of accident through image remotely.

This research proposed the method for application of SCORM in U-learning system. That is, I proposed the API broker to connect between U-learning and API Instance of RTE that is existing SCORM based learning object interface environment. The API broker operated handling process using request port and response port between SCORM and U-learning server. For efficient operation in each service, this system has learning contents service buffer in API broker.

In recent years, the pileup of world ports is deepening as time goes by due to China effect and continuous increase of world trade volume. The shipping companies try to reduce their shipping cost by using mega vessels in the ports. Shipping companies consider most of the ships turnaround time as a critical factor when selecting a calling port for reducing cost. This paper will suggest how we can guarantee terminal QoS like ship waiting time ratio and ship residing time applying RFID(Radio Frequence IDentification) technology, raising up rapidly as a fundamental solution of new growing industry to port information system. Also, lead time of whole port logistics can be decreased for reduction of loading & discharging time and result from productivity improvement of Twin-lift G/C(Gantry Crane} as applying RFID technology to terminal operation. The purpose of this paper suggests that the new business model of U-Port which port QoS can be guaranteed using RFID based RTLS technology.
