In global shipping logistics, it is important for users to keep track of the location of their continuously moving cargos. Analyzing the GPS data stream coming from the tag which is attached to the cargo, we are able to keep track of the cargo location in terms of going into or out of a certain logistics area using the information of the spatial relationship change between the tag and the logistics area. In this paper, we propose a simulation system for measuring the precision and false alarm rate of the cargo location tracking algorithm which generates spatial events over the global logistics areas. Due to the difficulty of experiment with a real tag, we developed a tag emulator to create a virtual tag which operates exactly like a real tag. We show the cargo location tracking system works correctly with the tag emulator which communicates with it using the same protocol as the real tag.

Recently it has become easier to figure out cargo positional information by using GPS(Global Positioning System) and wireless communication technology. The acceleration of globalization in the shipping logistics is ever more increasing the need to provide visibility, traceability and real time informations of entry, departure of vessel including cargo and status of logistic vehicle entry into each logistic base. Providing such positional information to logistics party by using wireless communication technology can bring effective operation of supply chain and reduction in logistics costs. In the previous paper, I suggested a global location tracking system based on GPS data in global shipping logistics by means of software using GPS data. However, the previous system had a problem of being inadequate to figure out a real time location movement information and was unsatisfactory on quickly searching and checking the location of global logistics hubs according to the longitude and latitude coordinates. Hence, in this paper, I suggest a real-time location tracking system that provided real-time location of the container cargos and logistics hubs can be searched quickly according to the GPS coordinates in global shipping logistics.키워드 :실시간 위치추적, 해운물류, 가시성, GPS

This study concerns the importance of workforce on job satisfaction, organizational commitment, and customer orientation through the change of global logistics industry and the operational condition of Busan port and Busan new port container terminals such as below. The purpose of this study is to firstly, that understand the current facilities and situation of container terminals in Busan port and Busan new port, and its changing environment of port industry. Secondly, provide basic information through the seeking whether the concept of importance of workforce is able to apply into container terminals. Thirdly, establish the theoretical system through the literature consideration on workforce on job satisfaction, organizational commitment, and customer orientation in container terminals. Finally, draw useful suggestions for managing container terminals through the structural relationship among variables, which are workforce on job satisfaction, organizational commitment, and customer orientation in container terminals.

This study aims to analyze a relationship marketing of freight forwarders, and based on this, customer's satisfaction, trust, and long-term relationship orientation are additionally analyzed. Through previous research, a relationship marketing of freight forwarders is considered, at the same time, the key factors of a relationship marketing is divided into reputation, physical feature, size, and professionalism. Targets of survey are companies which are registered in Korea complex transportation forward association. And a total of 292 questionnaires are collected from freight forwarder in Basan and Kyongnam from November 7 through November 18 in 2011. The result of hypothesis testing, show that relations between freight forwarders and customers is mightily important. In the future research, what effects of maintaining relation between freight forwarders and customers should be analyzed.
