SI(System Integration) process in KSLV-I development project is integrate whole assemblies which was submitted to system integration supervising team to one complete launch vehicle with proper quality control through test and verification and launch KSLV-I. It is not a one or a few teams' separate job but overall comprehensive job which request all related function group and manufacturing companies' voluntary cooperation. This paper was intended to provide entire SI process outline to whole related function groups and manufacturing companies for better cooperation in SI process and will be revised through continuos discussion among SI supervising group, whole function groups and manufacturing companies.

Korea augmentation satellite system (KASS) integration, verification, qualification (IVQ) activity is verification of requirements for KASS system and its sub-system that were performed based on the inspection, analysis, review of design, test (IART) method from factory acceptance test (FAT) to test readiness review (TRR) after critical design review (CDR) was closed. In the FAT phase, developed equipment was installed on the test platform and we were verified interfaces between sub-systems and coupling test with the kass control station (KCS). In the site aceeptance test (SAT) phase, on-site verification was conducted by installing equipment verified by FAT such as kass reference station (KRS), kass processing station (KPS), kass uplink station (KUS), KCS. However, considering the developed plan and status, SAT was divided into 3 phases and coupling test was performed. In the TRR phase, the KASS system verification was performed through FAT's test list and additional test list using the satellite based augmentation system (SBAS) broadcast signal from geostationary earth orbit (GEO) 1.

In this paper, we implemented total monitoring system in which LED light turned on only when user detected and LED light turned out only when user disappeared. This system is composed of two modules, one is HW board based on Micro Controller and the other is SW control system based on Web server. Micro controller board is based on ATMega2560 chip which is connected with Infra Red and Ultra sonic sensors. Web based monitoring system was designed can be used in smart device. The validity of this monitoring system was proved by integration test of two modules.

The Propulsion System Integration can be defined as the optimization technology of combining the propulsion system components with the airframe to achieve the overall aircraft misson performance goals. The disposition of propulsion system components on engine compartment enveloped by front fuselage and fire bulkhead is very restricted because of the interference with nose L/G and engine mountig strut. The design of components depends on the traditional technical data base. The engine satisfying a customer's ROC was selected among worldwide existing engines by the comparision studies of performance analysis with enigine installed effect, future growth potential, ILS, and application to aircrafts, etc. The ground test of the propulsion system integration was performed in the test cell and on the aircraft to assure the function of the components. The flight test was performed to confirm complying the performance requirements.

오늘날 과학기술 정보는 아주 다양한 곳에서 다양한 방식으로 생산 유통된다. 그러므로 원하는 정보의 위치나 각 정보 소스의 사용법을 모르는 사용자들은 일일이 정보 소스를 찾아 들어가 검색을 수행하여야 하는 번거로움이 있다. 본 논문에서는 사용자들에게 여러 곳에 위치한 과학기술 정보들을 한번에 검색하여 제공할 수 있는 과학기술 종합정보 시스템을 구현한다. 이를 위하여 KISTI와 (주)엔퀘스트에서 공동 개발한 분산통합검색 프로토콜을 사용한다. 사용된 분산통합 검색 프로토콜은 XML 기반으로 정의되어 있으며, 원천서버의 위치와 질의 형식 등에 관한 메타데이터를 유지하고 있어 분산된 서버들을 쉽게 통합검색에 참여 시킬 수 있다.

Avionics System Integration Laboratory is an integrated test environment for the integration and the verification of avionics systems. Recently, in order to fully consider the requirements verification of avionics system from the aspect of the entire system integration, the participation in the development of the SIL field is advanced from the requirement analysis of the aircraft. Efforts are being made to minimize the cost and the period of development of a SIL so that it does not affect the overall schedule of the aircraft development. We propose the avionics simulation model framework (ASMF) based on the modeling formalism applicable to SIL in order to reduce development period/cost and increase maintenance by standardizing the modeling methods of SIL.

Database Integration problems has been recognized as a critical issue for effective logistics service in logistics environment. However, researches related to effective methodology for this have been studied theoretically in the DB schema integration, are insufficient in the side of the system realization. The aim of this paper is to present a schema integration technique to integrate DB using XML( eXtensible Markup Language) in the part of practical DB integration, a quantitative methodology for the identification of conflict that is a representative problem on database integration. To achieve this aim, we extracted the entity name and attribute name from DB schema and suggested a quantitative methodology to easily fine name conflict that frequently give raise to a trouble when schema integration, based on the level of semantic similarity between attributes and entities.
