Education is a field that has tried to make use of the advantages of computers since they were introduced to the world. Intelligent Tutoring System and multimedia have become methods of teaching students of Computer Science, Education, Psychology, and Cognitive Science. Until now, they have been designed and produced only on the basis of a very specific domain and format. However, in the education field, most learners ask for integrated service that is practical, realizable, and sensitive to technological change. Therefore, in this study, we would like to present the technological and formal integration model as an ITS model which acknowledges changes in the fields of technology and education. As a technological integration model, the integration model of traditional Symbolic Artificial Intelligence and Artificial Neural Networks was presented. As a formal integration model, three integration models were presented according to (a) the process of learning diagnosis (b) learners' action behaviors (c) intelligence service respectively.

최신항공기 개발에서 증가추세에 있는 항공전자 장비들의 효율적인 통합시험 수행을 위 해 통합시험환경구축이 중요한 역할을 하고 있다. 특히 개발기간 최소화 및 신뢰성과 신속한 통합시험수행을 위해 통합시험장비 개발이 필수적이다. 본 논문에서는 수리온(KUH) 임무탑재장비(MEP)의 각 장비별 특성을 분석 후 최적의 통합시험 수행을 위한 장비별 모델개발을 다루었다. 모델은 동작특성에 따라 동적(Dynamic), 행동(Behavior), 연동(ICD) 모델로 구분하였으며 장비의 고장탐구 및 미장착된 장비의 동작특성 모사가 모델링의 주목적이다. 모델은 소프트웨어 단위시험 및 체계 통합시험 두 단계로 나누어 객관적 신뢰성을 검증하였다. 수리온 MEP 통합시험장비(SIL)를 이용하여 개발된 모델을 통합시험에 적용한 결과 설계 목적에 부합됨을 확인하였다.

We have developed a data integration system for ground-based space weather facilities in Korea Astronomy and Space Science Institute (KASI). The data integration system is necessary to analyze and use ground-based space weather data efficiently, and consists of a server system and data monitoring systems. The server system consists of servers such as data acquisition server or web server, and storage. The data monitoring systems include data collecting and processing applications and data display monitors. With the data integration system we operate the Space Weather Monitoring Lab (SWML) where real-time space weather data are displayed and our ground-based observing facilities are monitored. We expect that this data integration system will be used for the highly efficient processing and analysis of the current and future space weather data at KASI.

An intelligent system embedded with multiple sources of knowledge may provide more robust intelligence with highly ill structured problems than the system with a single source of knowledge. This paper proposes th hybrid knowledge integration mechanism that yields the cooperated knowledge by integrating expert, user, and machine knowledge within the fuzzy logic-driven framework, and then refines it with a genetic algorithm (GA) to enhance the reasoning performance. The proposed knowledge integration mechanism is applied for the prediction of Korea stock price index (KOSPI). Empirical results show that the proposed mechanism can make an intelligent system with the more adaptable and robust intelligence.

The application of computers and information technologies progressed with remarkable pace has paved the way for technological innovation toward the efficient integration of various functions in a manufacturing system. Actually it is observed that the greater part of manufacturing companies already initiated significant efforts to integrate information systems and attained the level of integration to some extent. The purpose of this paper is to clarify the strategic direction that manufacturing firms are pursuing through integrating information systems. Using the extensive data gathered from Japanese manufacturers, it is attempted to find the differences in competitive priorities and action programmes between the companies with high and low-level system integration. Our empirical data reveals that the manufacturers with highly integrated system are focusing their competitive capabilities on the rapid design change and new product introduction, and accordingly they place a greater emphasis on the action programmes related to design, process and quality improvement. As a conclusion, highly integrated firms tend to pursue new product development strategy more intensively, thereby they want to be a preemptor in the new market through exploiting technological advantages of integrated manufacturing system.

Regarding project management, many organizations have developed and distributed general project management knowledge systems, and application fields use the knowledge systems to apply the process suitable for characteristics of a project. This study suggests project management process models to apply to system integration projects. This system integration project management process model is composed of six top processes of initiation, preparation for contract, planning, implementation management, coordination and control, and termination and transfer. The five processes are re-divided into 25 bottom processes. These processes are expressed as input, control, output, and mechanism by using the IDEF0 model. For this model development, it has chosen the items which constituted a process through a questionnaire of experts.

Testing evaluation is a part of process for design, production, evaluation, operation and abolition, and is the process of certifying system performance. The main purpose of testing evaluation is to reduce the risk factor under the determining process. Testing process has the three step such as design qualification, integration and validation test in factory, system integration and commissioning test. Design Qualification is to verify errors on the design process. Integration and validation test in factory is for the H/W and S/W of an equipment and is to verify interface of subsystem, communication protocol and main functions. System integration and commissioning test is a functional test to adjust successful installation of equipment. According to the testing process, briefly consideration for test item, test method and test contents about signalling system is carried out.

Needs of automation and computerization in the construction industry has been recognized but the implementation of e-business solutions with project management systems has not been fully explored. In order to cope with different management practices in home office and project sites, integration of two popular systems, Enterprise Resource Planning (ERP) and Project Management System (PMS) is essential. The objective of this study is to find ways to functionally and systematically integrate ERP and PMS. With the integration of ERP and PMS, a project will be managed much more efficiently and effectively. It is expected that this study will benefit system integrators and help them to understand construction management processes and integrate the solutions with minimized programming work.

무인기 개발 시 항공전자시스템의 요구도 검증을 위해 통합시험능력을 제공하는 통합시험환경(SIL)을 개발하였다. 개발된 SIL은 유인항공기 SIL이 보유하고 있는 기능들을 기본적으로 제공하며, 각 구성품인 지상제어 모의, 비행체 모의, 비행환경 모의가 폐루프(Closed-Loop)로 연동되는 구조 하에서 시험 데이터의 가시화 및 시험자동화에 중점을 두고 설계되었다. 이로써 무인기의 복잡하고 수많은 요구도가 개발된 SIL을 통해 간편하고 정확하게 검증될 수 있었다. 개발된 SIL은 4단계의 검증과정을 통해 기능 및 성능의 정확성과 신뢰성이 검증되었으며, 무인기 지상체 및 비행체 통합을 위한 체계 SIL에서도 정상 동작함을 확인하였다.
