본 연구에서는 물류정보시스템을 도입활용하고 있는 무역업체들을 대상으로 내부업무효율성과 조직혁신정도를 조절변수로 하여, 내부업무효율성과 조직혁신정도가 높은 집단과 낮은 집단으로 구분하여, 이들 각 집단의 물류정보시스템 특성변수가 성과(이용자가치와 인식된 유용성)에 미치는 영향을 분석하였다. 연구결과, 구조화된 업무 환경에서 물류정보시스템을 통한 지속적인 업무수행과 더불어 조직혁신을 위한 기업차원에서의 노력이 병행되어야 하며, 물류정보시스템 도입 무역업체들은 정기적으로 기업의 업무활동전반에 대한 정확한 평가와, 전략수립을 통해 물류정보 시스템의 성과 제고를 위한 노력을 기울여야 할 것이며, 본 연구에서 나타난 바와 같이 물류정보시스템 도입 무역업체들의 낮은 조직혁신정도를 향상시킬 수 있는 조직자체의 각성과 노력이 뒤따라야 할 것이다.

In the paper We have analyzed the case study of the domestic and foreign railway logistic information systems based on the railway logistic to build the information architect basis system of real-time simultaneous. In case of domestic examples, We have analyzed the logistic information system used in Korea Railroad and the information systems of Kyungin ICD(Inland Container Depot) and Busanjin CY(Container Yard). In case of foreign example, we have analyzed the logistic information system of Japanese FRENS(Freight information network system) and the examples of freight tracking using RFID(Radio Frequency Identification). Through the above analysis, We have induced the main problems and improvement methods. We are able to build the railway-oriented information network system for the massive and efficient railway transportation.

The development of information communication technology leads the growth of logistic industry including delivery service as well as electronic commerce. The researchers predict that it will be still improving for the next several years. The logistic information system of railroad courier has been growing for a long time with small-package delivery transportation which is similar to the land-road delivery system. Despite of the long-time growth, it is recently in pain of the great loss since the 1990's, due to the failure to satisfy the customer's need for door-to-door delivery service. But the logistic information system of railroad still has the great potential. There are so many benefits such as timeliness, Punctuality, speed, multi-node storage base, transportation efficiency, energy frugality, environmental sociability, and so on. If the railroad logistic system plays a role of a portion of the nation-wide logistic with other logistic system, the synergy through the balancing logistic will also get much of international competitive advantages. So the objective of this research is to design the model and prototype of the web-based logistic system from which railroad service provider(Korean National Railroad), delivery service providers, and the customers can share the best effective delivery information.

Recently, RFID has emerged as the main technology in the logistic services. When the existing recognition technology based on bar codes brings about lots of problem due to its own limits. RFID becomes the center of attention to solve them. However, RFID is not without any obstacles: companies have their own operating systems, while RFID is developed regardless of each company's special features. RFID middleware system based on web service is expected to remove these obstacles. This paper shows how to operate the middleware based on web service and to lay in the DB the tag informations taken from reader system. Middle assures that companies adopting RFID system for their logistic service are given adaptability to any systems whatsoever, available by way of defining logistic information, tag information and reader information. For this purpose, we implement as the basic web service a middleware system that turns all data into XML(eXtensible Markup Language) of SOAP (Simple Object Access Protocol), the standard data.

In this research we present a new model, PLCM(Cort-Logistics Chain Management), which can cooperate each other in the port-logistic industry that occupy a heavy rain in the Northeast Asian economy. PLCM(Port-Logistics Chain Management) synthetically manages the logistic chain and information laying stress on the port. Unlike SCM, which hat a vertical relationship between the main groups to cooperate each other, PLCM has a horizontal relationchip between the ports to achieve common purpose and to improve their whole competitive power. In this research we present a concept of PLCM and a specific plan to develop a system for PLCM targetting Pusan, Shanghai, and Tokyo Port which occupy a heavy rain in the Northeast Asian port industry. This system is composed of integrated information system and EDI document exchange system according to the special quality of user's request information. And in order to prove its feasibility and validity, the case study sailing from Shanghai to Busan has been applied to this study.

The standard logistic map is an iterative function, which forms a discrete-time dynamic system. The chaotic logistic map is a kind of ergodic map defined over the unit interval. In this paper we study the limiting behaviors on the several processes induced by the chaotic logistic map. We derive the law of large numbers for the process induced by the chaotic logistic map. We also derive the uniform law of large numbers for this process. When deriving the uniform law of large numbers, we study the role of bracketing of the indexed class of functions associated with the process. Then we apply the idea of DeHardt (1971) associated with the bracketing method to the process induced by the logistic map. We finally illustrate an application to Monte Carlo integration.

미래전은 정밀 타격과 같은 첨단 군 기술에 의한 효과 중심의 마비전이다. 이러한 미래전에서 작전 주도권과 집중력 강화를 지원하기 위한 새로운 개념의 군수 역할이 요구되고 있으며 전투원 및 전투부대 중심의 집중군수가 대안으로 제시되고 있다. 이와 같은 집중 군수를 실현하기 위해서는 전 제대의 자산을 실시간으로 파악 할 수 있는 자산가시화가 선행되어야 하지만 현재 우리 군에서 사용하고 있는 군수정보체계는 제한적인 정보만을 제공하고 있다. 본 연구에서는 웹 기반 2종 및 4종 군수품 관리 시스템의 구현 방안을 제시하였다. 제시된 대안 체계 시제는 전투원 및 전투부대 중심으로 군수가 지원될 수 있도록 전투부대 중심의 업무 프로세스 통합과 군수 기능간 동기화를 추구하였다. 또한 집중 군수의 필수 요소인 자산 가시화를 제공함으로써 이를 통한 신속하고 효율적인 군수 지원이 가능함을 확인하였다.

With the rapid growth of e-logistics in the global logistics industry, it is important to gain further insight into this growing segment of Chinese logistics industry. The current situation in China consists of many small and medium-sized logistics firms. Furthermore, e-logistics is still relatively undeveloped in the majority of the Chinese logistics companies and presently there are still many problems unresolved. This paper attempted to review the concepts and theoretical background of e-logistics systems from previous studies. After acknowledging the essential issues related to e-logistics systems, a research model based on the theory acceptance model was designed and tested. The key factors to the e-logistics system (reliability, maintainability, software, facility and transportation) were validated through the modeling and testing process. Included in the modelling and testing process are other related factors of e-logistics process, logistics information system and added value as dependent variables in this model. The results of this study confirm that the e-logistics Process is affected by transportation, while maintainability and software factors influence logistics information system. reliability, maintainability, facility and transportation are significant factors associated with added value. This research aimed to provide theoretical and practical contribution to Chinese logistics companies and to give some insights into e-logistics system as a whole. The paper also provided some useful theoretical implication and practical guidelines for the development of e-logistics system in the chinese logistics industry.
