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.

본 논문에서는 명세를 기반으로 한 통합 테스트를 수행할 때 사용되는 시나리오 작성지원 절차를 제시하고, 시나리오 작성지원 도구를 구현하였다. 이를 위해 기본적으로 요구사항 정의테이블, 프로세스 정의테이블, 프로그램 대 테이블 상관도를 사용한다. 추가로 앞의 3가지 테이블 기능을 요구분석, 설계, 테스트 단계별로 나누어 한곳에서 신속·정확하게 체크할 수 있는 요구사항 추적테이블을 생성한다. 본 연구의 통합 테스트를 위한 시나리오 작성지원 도구의 출력물은 시나리오 작성을 위한 지침서 역할을 한다. 그 결과 검사팀의 시나리오 작성노력을 상당부분 줄일 수 있을 뿐만 아니라 요구사항의 누락을 방지하고, 해당 프로세스에 대한 테이블 정보를 알 수 있으므로 테스트할 때 잘못된 값을 입력하는 것도 방지할 수 있다.

This study is about user satisfaction of the Junior College Library based on its characteristics of space composition. For this, we studied characteristics of space composition targeting the libraries in colleges in Seoul and Gyeonggi-do. First, in case of study of characteristics of space composition for books and library data, student satisfaction for traditional and normal library areas was high. It means that the service based on library areas should start from normal library areas as well as there is a change about space as the type of data in libraries change to electric data and multimedia. Second, If we look at the space for a reader and a user, satisfaction for a normal reading room was high. we can also see that satisfaction for a computer room and a multimedia reading room was not higher but still high. Also, the reason why satisfaction for a multimedia reading room that provides various activities was high was that the complex of a library space is needed to provide users with various activities. Third, in case of space for programme function and meeting, satisfaction for the room of video information and the group study room was high. we can see that user satisfaction for the space got high basically when a user is satisfied with the proper information technology based on interaction Fourth, as a result of variance analysis of 3 spaces of Junior College Library and the services, the size of the space of service does not influence user satisfaction directly. Even the space is small, if it decorates variously like with a lighting for a user, a window seat to meet the nature of users and has specific factors such as space reservation using internet, user satisfaction is high. If we summarise the result of this study, to make user satisfaction for speace in a Junior College Library higher, not just we need to try to make it extend as a educational, a cultural place but we also need to accept the student's requirement that the space also needs to be extend as a complex cultural space.

User Requirements are analyzed and quantified by decision making models and system engineering methods to select alternative concepts which satisfy the various requirements. In this study, the design concepts for guided missile are derived using Quality Function Deployment(QFD) and Analytic Hierarchy Process(AHP). The design alternatives that satisfy the user requirements are extracted by QFD and Morphological Matrix, then the best design concept are obtained using AHP and Pugh concept Selection.

Participatory sensing applications rely on recruiting appropriate participants to share their surrounding conditions with others, and have been widely used in many areas like environmental monitoring, health care, and traffic congestion monitoring, etc. In such applications, how to ensure the privacy of a participant is important, since incentive mechanisms are used to maintain their enthusiasm for sustainable participation by offering certain amount of reward. In this paper, we propose a pseudonym-based privacy protection scheme, that takes both privacy protection and user incentives into consideration. The proposed scheme uses the pseudonym mechanism and one-way hash function to achieve user incentives, while protecting their identity. We also show extensive analysis of the proposed scheme to demonstrate that it can meet the security and performance the requirement of a participatory sensing application.

In this study, we first define user requirements to fulfill the reconnaissance and the search missions, by analyzing the system characteristics and operation environment. By investigating the design technology level, the development and procurement costs, the strong system design concepts and possible alternatives will be proposed. To analyze the system requirements, the Quality Function Deployment of the systems engineering approach will be implemented. The promising design alternatives that satisfy the user requirements are extracted by constructing the Morphological Matrix, then the best design concept will be obtained using the Pugh Concept Selection Matrix and the TOPSIS(Technique of Order Preference by Similarity to Ideal Solution).

In this paper, we analyse security threats and security requirements about the designated PC solution which restricts usable PCs that are only an user own PCs or a registered PC for online banking or very important services. Accordingly, causable threats of the designated PC solution are classified a process, a network layer, a software module, and an environment of platform, and we draw security requirements based on analysed security threats. Results of this research are considered utilization of criteria for improving security of the designated PC solution and standards for giving hint of imposition of the designated PC solution.

Systems Engineering Approach was applied to the development of operator-support core management system based on the on-site operation experience and document of core management procedures, which is for enhancing operability and safety in PHWR (Pressurized Heavy Water Reactor) operation. The dissertation and definition of the system were given on th basis of investigating and analyzing the core management procedures. Fuel management, detector calibration, safety management, core power distribution monitoring, and integrated data management were defined as main user's requirements. From the requirements, 11 upper functional requirements were extracted by considering the on-site operation experience and investigating documents of core management procedures. Detailed requirements of the system which were produced by analyzing the upper functional requirements were identified by interviewing members who have responsibility of the core management procedures, which were written in SRS (Software Requirement Specification) document by using IEEE 830 template. The system was designed on the basis of the SRS and analysis in terms of nuclear engineering, and then tested by simulation using on-site data as a example. A model of core power monitoring related to the core management was suggested and a standard process for the core management was also suggested. And extraction, analysis, and documentation of the requirements were suggested as a case in terms of systems engineering.
