지적 객체는 지적소유변경, 토지 분할/합병, 토지 영역경계 변경 등의 사건이 발생함으로써 비공간 또는 공간 속성이 변경된다. 이러한 변경에 대한 정보는 지적 객체의 이력으로써 지적 관리 시스템에 저장된다. 사용자는 단일 지적 객체가 가지는 전체 이력 또는 특정 시점이나 기간 동안의 지적 객체 상태에 대한 질의를 수행할 수 있고, 과거 지적 객체가 가졌던 속성 및 형태를 확인하거나 현재의 속성 및 상태와 비교하여 지적 객체의 소유변경 내용, 행정구역상 지번/지목의 변경 과정, 영역 경게 변경 과정 등과 같은 정보를 얻을 수 있다. 이 논문은 시간 지원 지적 관리 시스템에 사건 지향 시공간 데이터 모델인 이력 그래프 데이터모델을 적용하고 객체 단위 이력 질의를 위한 시공간 연산자를 제안함으로써 시간 지원 지적 관리 시스템을 위한 객체 이력 관리 기법에 대해 설명한다.

The tracing system means that the system can follows, traces, and records every steps of production and delivery of goods and its ingredient. Specially, Koreans have big concern about food tracing system which is influential for health directly. We were more interested in medical herb using in oriental medicine than any other things. We proposed the process and design of tracing system for medical herb based on RFID(Radio Frequency IDentification) technology in this research. This study shows current medical herb tracing ways and RFID code system by using for world standard. Firstly, We designed the new process of traceability of medical herb with various preceding references based on RFID technology. Secondly we suggest that RFID code configuration using the international standard code(ISO code) and korean agricultural and marine products code for the proposed process. RFID code system is very important because this plays a means of identification for tracing about medical herb. The proposed code system have the elements as Issuing Agency Code, Issuer Number, inspection information, inheritance flag, area code, modified agricultural and marine products code, serial number in 96 Bit length. Lastly We defined the code-generation process in the tracing system.

Recently, it is expected that the agricultural and stockbreeding industry are damaged by the China-Japan-South Korea FTA and FTA between the United States and South Korea. After free trade, it is increasing to import crops, aquatic products, and livestock which are produced in a foreign land. But it is affected negatively to the trust relationships and markets, because of breaking it out that low grade foreign products are turned into domestic products. For this reason, we need the traceability management system. In this paper, it designs and implements the traceability management system using RFID and USN providing distribution traceability information as well as the traceability information of the growth environment, automatic control according to the facility growing and monitoring of the storehouse. The implemented whole systems consist of the growth environment monitoring and the traceability management. First, the growth environment monitoring shows the environment of plantation and automatic controller of the storehouse and growing facility. This growth environment monitoring information provides the detailed information about growth environment and writing the farming diary automatically by producer. Second, the traceability management provides all of the traceability information such as production, shipment and consumption to consumers. The traceability management system that has been designed and implemented using RFID and USN in this paper, provides the u-IT agriculture to producer and the reliability about agricultural products. In addition, this system provides the foundation data to operate GAP and HACCP, and becomes the advantaged agricultural products of the interior of a country by application of this system.

Recently, the renewable energy resources play an important role as an energy resources of future due to an environmental pollution and lack of resources and so on. The development and diffusion of information systems related to renewable energy resources have been driven actively abroad. However, at domestic an efficient history management for renewable energy resource data and web retrieve service are not provided. Therefore, in this paper, we propose a history data management system for the renewable energy resources, which stores and manages vast history information of renewable energy resource data systematically. This system collects renewable energy resource data in the outside observation system and stores them in the history database. The stored Information is retrieved through the history query process and can be provided in various forms - table, graph, chart and counter line, etc. - on the internet. Especially, the proposed system manages the history data in real-time so the latest information is always provided to the users through the web interface.

GIS Tools is able to not only store the integrated information between attribute data and spatial data, but also analyze them. Most of GIS Tools support current information of land. However, lawsuit of right of possession as well as statistic of past data for land policy may need historical information. Therefore, in the paper, we designed the spatiotemporal operators what can handle the historical information. and implemented them. The spatiotemporal operators are used in the history management system of Cadastre and Cadastral map based on GIS. The historical information is generated in spatial operation of spatiotemporal operators and then the implemented operators provide a function to store the historical information, and handle them.

In this study, IT based traceability system which is able to measure weight and moisture content of grain in the post-harvest process of intake, drying, storage and milling was developed in RPC(Rice processing complex). Measured information of weight, moisture content, yield, loss and quality was saved in the DB sever. Simultaneously, lot No. was generated and connecting to quality and traceability information. Also, automatic control system with MMI(Man Machine Interface) and yield and inventory control system(YICS) for grain was developed for the traceability system by applying the TCP/IP communication. In addition, simulation of system was performed for evaluation in RPC.

시간지원 데이터베이스는 시간에 따른 이력데이터가 단조증가 형태를 띄고 있는데 반해 이력질의는 주로 최근 생성된 데이터에 관한 질의 비율이 상대적으로 높다. 또한 방대한 양의 데이터를 관리하기 위해 3차 저장장치를 효율적으로 사용할 필요가 있으며 이를 위해 시간지원 데이테베이스 관리시스템은 특정 시간마다 이력데이터를 3차 저장자치에 이동시키는 버큐밍(Vacuming)작업을 수행한다. 이 논문에서는 이력데이터 페이지와 현재 데이터 페이지의 시간선상에서의 참조 빈도수를 고려하며, 이력질의에 대하여는 페이지의 과거의 참조밀도 이력을 고려하여 버퍼를 관리하는 LRU/PRD기법을 제안한다.
