This paper describe the most advanced database management system for the mobile number portability(MNP) in the world The database management system can process the procedure of porting_out and porting_in in 30 minutes and it is the shortest time in the world. The MNP DB management system consists of two functional blocks, one is for the call processing system and the other is for the management of subscriber of MNP. The hardware and processing algorithm are presented in this paper. The DB for call processing is located at each mobile operator and be called local number portability database (L-NPDB). The DB for the management of subscriber of MNP consist of L-NPDB and master database which is located at the Korea telecommunications operators association(KTOA). The hardware database system for MNP consists of the interconnection system of master-NPCDB (NP customer database, M-NPCDB), local-NPCDB, M-NPDB and L-NPDB. The master database is interconnected to the local database through dedicated line and can process any MNP service in real time. The presented MNP structure in this paper has been implemented in Korea and became the most effective and advanced DB management system for MNP in the world.

Through USN (Ubiquitous Sensor Network) is collected the patient's vital information in real-time, also information collected will be stored in the DB (Date Base), frequent use hospital saved patient's vital information for DB. Stored in the patient's vital medical information stored in the patients with frequent hospital patient to hospital if the patient's vital information is stored in DB. But, stored location is within hospital server or stored in a PC environment, because If utilize other Hospital existing hospitals will need to request. However, Existing hospital have problem for security, authentication, management, cost, manpower, such as, because other hospitals and the exchange of information does not come easily. So, If has the advantage of the patient and the patient's vital information is stored on mobile devices that you can use as DB. It is important to find information quickly and accurately, in this study, Is A study on mobile circulation loop DB systems for patient-centered serbices.

The established NEIS has a lot of problems in the management of security. It does not realize access control in following authority because it only uses PKI certification in user certification and the use of central concentration DBMS and plain text are increased hacking possibility in NEIS. So, This paper suggests a new NEIS for the secure management of data and authority certification. First, we suggest the approached authority in AC pf PMI and user certification in following the role, RBAC. Second, we realize DB encryption plan by digital signature for the purpose of preventig DB hacking. Third, we suggest SQL counterfeit prevention by one-way hash function and safe data transmission per-formed DB encryption by digital signature.

최근 전자우편이나 해킹을 통한 피싱과 파밍 등 금융 사기가 많이 발생하고 있다. 이에 이러한 피해로부터 사용자의 경제적 손실 및 개인정보 보호를 위하여 웹 사이트 인증, 전자우편 인증 등의 연구가 진행되고 있다. 기존 인증 방법에서는 WBL (Website Black-List) DB를 사용하였는데, 피싱의 짧은 생명주기(life cycle)로 인해 WBL DB의 유효성은 떨어질 뿐만 아니라, 피싱 사건 발생 후 웹 사이트가 WBL DB에 등록되기 전까지는 확인 불가능하다는 단점을 가지고 있다. 이러한 문제점을 극복하기 위해 WWL (Website White-List) DB를 이용한 연구가 진행 중이지만 아직은 미비한 편이다. 이에 본 논문에서는 기존의 WBL DB와 WWL DB를 이용한 방법이 가지고 있는 한계점을 극복하기 위해 WWL DB 항목을 정의하고, 이를 이용하여 웹사이트 보안 위험도를 정량화할 수 있는 웹사이트 위험도 산정 기법을 제안한다.

This research developed the RMIS(Risk Management Information System) which focus on works of risk management fields required of apply of a space information, and focus on the DB to establish and apply the space information efficiently with research scope on the LPG refueling station in city. On the basis of the RMIS, this research provides the baseline to lead on an efficiency of safety inspection of LPG refueling station, advance risk assessment, and efficient making decision of an accident correspondence assessment with interlocking the GIS representing risk through the automation of a quantitative risk assessment standardize requirement to control at real-time. The RMIS development process is as follows. firstly, Relational Database(RDB) was developed by using fundamental data both On-site and Off-site relating data as peforming risk assessment on the LPG refueling station in city. Second, the risk management integral database system was developed to monitor and control the risk efficiently for user with using the Visual Basic Program. Third, through interlocking the risk management integral database system and the GIS(Falcon-map) was suggested the decision making method. Represented results through out the RMIS program development are as follows. Firstly, the RMIS was established the mutual information to advance management the risk efficiently for user and inspector with using the risk management data. Second, as this study managed risk for on-site and off-site separately and considered effect for inside and outside of facility, constructed the basis on safety management which can respond to major accident. Third, it was composed the baseline to making decision that on the basis of user interface.

현재 지방자치단체에서는 각자 도시기반시설물관리시스템을 구축하여 활용하고 있다. 그리고 GIS DB 구축 시, 같은 속성 값을 가지고 있는 시설물에 대해서도 중복 작업을 진행하고 있다. 각 지방자치단체가 관리하고 있는 시설물의 대부분은 공통된 시설물을 대상으로 하고 있지만 DB 속성항목에서 다소 차이가 나고 있다. 이에 공통된 동일 시설물에 대해서는 DB의 속성항목을 표준화하고 시설물의 사양을 표준화하여 각 시설물 사양에 따라 ID를 부여하여 도시기반시설물 전자라이브러리(Electronic Library)를 구축하는 방안을 제시한다.

This study mainly concentrates on the development of a land information management system to manage the land related information in an effective way for the water-pollutant buffering zone, which was established to sustain better quality of the drinking water over the upper part of the Han river. For developing such system, a procedure was implemented covering user requirement analysis, system design, spatial DB design, and coding. DB linkage with affiliated institutes and cadastral DB updating were proposed as the part of the efforts to enhance the applicability of the system. In addition to that, modularization was adopted for more efficient and cost-effective system development.

This study is aimed at the development of ubiquitous based road disaster management system. The fundamental technologies used for developing this system are classified into three modules - wireless internet communication module, mobile module and server module. These fundamental technologies can be used not only for developing road disaster management system but also for developing various mobile or ubiquitous systems. With this system, workers can download many DB (Digital map, Attribute information etc.) from server to the field in realtime. The accuracy and objectivity of the DB could be improved with these informations collected at fields because these data can be used as basic data for road disaster information collection. Because in the web based server module - Web based Road Disaster Management System (URDMS) - field disaster information was showed link up with exist DB on road by absolute coordinate, the decision making with all of the field information was made and it sent to a field staff in realtime. The problems of current road disaster management rule ran be solved by this URDMS.

A company needs low cost and high efficient S/W tools to improve the white color productivity in daily operation, These needs may be satisfied by end-user knowledge management system to be suggested in this paper. We suggest that the end-user knowledge management is not made by specialized developer but directly made by end-users of some related managers using company-wide DB and department DB. We expect that this end-user knowledge management system will increase the efficiency of end-user daily operation and minimize the total life cycle cost of end-user computing system in industry. The suggested end-user knowledge management system has been tested in some companies through the training course.
