Recently, as change in global logistics environment, various issues have been presenting. These issues are including the pursuit of low cost-high added value, the realization of sustainable logistics system, the protection of environment, and the development of ubiquitous techniques. To cope with these environment changes and improve the national logistics system, the government have carried out various logistics policies and pushed ahead development of national logistics information network. But still, from a view-point of national logistics, there are several inefficient elements such as information connection and utilization, code/data standardization. In this paper, the survey result of global logistics environment change, logistics policy of a developed countries, domestic logistics policy and information system status will be presented. And from these status, suggestive points are mentioned. Finally the status of railway logistics information and future developments are presented.

To cope with these environment changes and improve the national logistics system, the government have carried out various logistics policies and pushed ahead development of national logistics information network. But still, from a view-point of national logistics, there are several inefficient elements such as information inconnection and code/data unstandardization. In this paper, the survey result of domestic inland-logistics information system status will be presented and the future developments will be presented for the efficient national logistics.

Number of researches on efficient terminal operation system applying RFID(Radio Frequency Identification) are in progress. However, RFID has limitations on tracking and providing accurate positions of containers. In this paper, to enhance the performance of the integrated terminal operation system, an efficient loading management of yard is proposed by applying RFID based RTLS(Real Time Locating System) that provides real time accurate positions of containers. It was found that a group based sequence system is more efficient than the existing individual sequence number system in the container yard In the group based sequence system, the containers in the same group should have similar characteristics such as port of destination(POD), size, weight, etc. In order to run this system, we proposed the parameters to the unspecified N bytes of RFID tag which are specified in ISO 18000 7. And then, we developed an integrated operation system of container terminal using RFID. The proposed system reduces the ship turnaround time in ubiquitous port environments.

Nowadays, ubiquitous computing services begin to be suggested from a few domains such as supply chain, logistics, and location-based services. However, to what extent the services will be successful is hard to be estimated, mainly because a sophisticated service evaluation method focusing on the ubiquitous computing perspective has not been supplied. Hence, this paper alms to build a model to assess the quality of ubiquitous computing service. To do so, an amended model, Ubi-SERVQUAL, is applied to assess the service quality mentioned in ubiquitous computing scenarios. According to the Ubi-SERVQUAL, we found that an actual service with higher quality should consider reliability. responsiveness, assurance and empathy in order to increase customer satisfaction, computer system's intimacy with users and trust.

Logistics creates a boom in accordance with the recent new technique's development along with the recent RFID/USN of ubiquitous computing technique. The wave of 4PL(Fourth Party Logistics) that added the strategic consulting based on new IT techniques to logistics outsourcing through existing 3PL service with is a great issue. Moreover, the customer enterprises which contained manufacturers and distributors need the one stop service, therefore a method for effectively dealing with global logistics' environment changes is needed. Above all, a development of the 4PL system with RFID is very urgent. We developed the RFID u-4PL system progressed more than the present system, in which we applied many international standards. Finally, we constructed the web service based on Web 2.0 because of important condition of 4PL.

A recent advance in RFID technology is one of the major technological drives in reducing cost in logistics, distribution and even in the manufacturing sector. However, currently the technology is practically accepted only in the area of logistics and inventory control. The characteristic of these application areas is that the technology is used in the controllable environment. In this paper, we discuss a case study of using active and passive RFID technologies to automatically gather process information in the mold factory. Active RFID tags are attached on the main parts of molds and their positions in the floor are tracked with the routers. We also discuss on the idea of using mobile device with RFID reader to inquire information for molds on the spot in the factory floor. The inquirable information includes 3D design data and basic mold data. The paper shows implementation results with hardware configuration for the testbed.

최근 물류의 양이 증가함에 따라 빠르고 정확한 물류처리가 요구되어 지고 있다. 특히, 광역 물류 환경에서 게이트웨이로서의 역활을 수행하는 항만에서의 물류처리는 무엇보다 중요하다. 본 논문에서는 항만에서 보다 신속, 정확한 물류 처리를 수행하기 위한 스마트 태그 시스템을 설계 및 구현한다. 스마트 태그 시스템은 사물의 정보를 인식하는 능동형 RFID, 컨테이너의 보안을 담당하는 전자봉인 장치, 그리고 사물의 위치를 파악 및 추적하는 RTLS 시스템으로 이루어져 있다. 물류 환경에서 사용되어는 인식 기술은 이종 시스템들에서 판독되어지므로 표준과의 호환성은 중요하다. 본 논문에서는 표준과의 호환성을 유지하는 방법을 소개하고 검증을 수행하였으며, 스마트 태그의 수명, 인식률 및 인식시간 등과 같은 시스템의 성능을 분석한다.
