Small-sized domestic logistics-companies are required to satisfy the high quality of logistics information service. However, these companies are not prepared to complete customers' requirement because of the e-logistics process, excess of logistics distribution steps, and so forth. Moreover, large-sited foreign logistics companies are going into domestic market and trying to share the market. In this paper, we propose an ASP-based real-time Logistics Information Control System using location-based service(LBS) and logistics information service to reinforce the competitiveness of domestic logistics-companies and improve the customer service quality. This system is designed to trace and control the real-time logistics movement information by using GPS and to process the transportation information by using SMS.

본 논문은 제주 택시 텔레매틱스 시스템에 축적되고 있는 차량들의 이동이력 데이터에 대한 처리구조를 설계하고 구현한다. 각 차량은 1분마다 자신의 위치와 GPS 정보 및 택시의 상태에 관련된 보고를 발생시키며 중앙의 관제시스템은 이를 수합하여 이력데이터를 구성한다. 본 논문에서 구현하는 시스템은 위치 보고를 처리하여 인코딩 변환, 좌표 변환, 맵 매칭, 도로상에서의 위치 계산 등을 수행한 후 오라클 데이터베이스의 이력 테이블에 저장하도록 한다. 이를 위하여 도로 네트워크가 데이터베이스로 변환되었으며 도로망에의 가시화를 위하여 지도 인터페이스 프로그램이 구현되었다. 이러한 정보들은 이력 테이블과 아울러 공간 데이터베이스 엔진과 결합하여 C 언어나 SQL 문장에 의하여 다양한 위치기반 질의를 가능하게 할 뿐 아니라 배차 정보 분석, 현재 통행 속도 분석 등 부가가치가 높은 정보를 산출하는데 필수적인 역할을 수행한다.

Among the various application to use FRID, the parking control system widely uses it recently. However, it is rare for the existing systems to integrate several parking lot in the clustered shopping center. This paper proposes the integrated parking control system based on RFID. The system searches optimal path to parking lot with due regard to the position of users who own a tag and the status of parking lots. Then, it transmits the path to mobile devices of the users. The system consists of main server, middle ware to filter and manage tag information, parking lot client to send and manage the status of each parking lot and application module of mobile devices based on WIPI for displaying the optimal path. The main server integrates these components by a database and a new method to filters and manage tag information is newly proposed for the sake of maintaining the position and the direction of the cars in the middle ware. The implemented system shows that it is highly expected to be useful in an advanced integrated parking control system.

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.

HACCP is a scientific and systematic program that identifies specific hazards and gives measurements in order to control them and ensure the safety of foods. Transportation of livestock and its products is one of the vulnerable sectors regarding food safety in Korea, as meats are transported by truck in the form of a carcass or packaged meat in a box. HACCP application and its acceleration of distribution, in particular transportation, are regarded as important to providing consumers with ultimately safe livestock products. To achieve this goal, practical tools for HACCP application should be developed. Supply chain management (SCM) is a holistic and strategic approach to demand, operations, procurement, and logistics process management. SCM has been beneficially applied to several industries, notably in vehicle manufacture and the retail trade. HACCP-based real-time visibility system using wireless application (WAP) of the livestock distribution is centralized management system that enables control of temperature and HACCP management in real-time for livestock transportation. Therefore, the application of HACCP to livestock distribution (transportation, storage, and sale) can be activated. Using this system, HACCP management can be made easier, and distribution of safe livestock products can be achieved.
