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.

This study is on the behavior analysis which can define and verify a system requirement through a behavior diagram for High speed rail system. The model considered in this study is limited to the preconditioning control of the control system specification for HSRS. To build an executable model, requirements should be decomposed first into leaf node requirements. The behavior model is composed of input, output, and functions which are linked with leaf node requirements. It is important that a single requirement must specify a single Auction. Using the developed executable model and the traceability between requirements and functions, this study found out a lot of static and dynamic inconsistency, missed and derived requirements. This is to develop and executable behavior model to do functional analysis and be able to verify the integrity of a specification.

Traffic engineering function consists of traffic management, capacity management and network planning. In this paper, we present the requirements for each functional traffic management, and also present functional and process model to efficiently to handle the traffic engineering for multimedia internet services. Finally, the traffic management methods for each step are described in detail.

Tight integration of product design and process planning in the early design stage would make bigger impact as wider spectrum of design and manufacturing alternatives can be pursued and evaluated. Thus the development of systematic computer-based support for this integration is desirable. For this integration and process planning in the early design stage. the systematic method to synthesize shape of part from functional requirements is crucial. This research presents the methods of functional decomposition from overall function or product and synthesizing shape of part based on functional relations extracted from functional decomposition using planetary gear transmission system as an example.

All medical information system stakeholders and the environment exists. Medical information systems for development in these environments and non-functional requirements, functional requirements and quality goals are to be met. In order to achieve these goals in a variety of ways currently being made to develop information systems and various applications are emerging. However, the process of developing these health information systems meet the basic requirements and does not consider that from the point of view should not be separate. This study of the development of health information systems related to quality measurement indicators for the analysis software architectures, and medical information, information quality evaluation of service quality information associated indicators evaluation are offered. This way of associated indicators for the quality of the output sum and analyze the trends in software architecture u-Healthcare should be available for assessment. Quality score compared with pre-set goals for achievement and satisfaction levels of analysis further support the cause excerpt field use in analysis and improvement is possible.

We compared nanotechnology web portal requirements using a Kano method, to identify similarities and dissimilarities in Kano-categorizations of features and functions required of nanotechnology among users in universities, government research institutes, and industry. Based upon data obtained from 130 user members of the National Nanotechnology Policy Centre, this study analyzed assessed asymmetries in web users' feelings based on hypothesized provision and non-provision of web portal requirements. In doing this, this study utilized measures and procedures suggested in the literature such as the most frequent-response categorization, customer satisfaction (dissatisfaction) coefficient, category strength and total strength, and Fong test. This study found that overall, sectors were an important factor in explaining the relationships between web portal requirements and user satisfaction/expectations. When these requirements were classified, users' perceptions of information contents requirements were consistent across the sectors, but the other functional requirements including communication and collaborations considerably varied.

As the cases of merging and cooperation of archives and libraries increase abroad, research and discussions about integration of complex information services among information centers, such as archives, libraries and museums started to emerge. In a similar vein, the need for integrated cultural information centers are suggested in Korea as the museums encounter the need for expansion of contents, and libraries try to diversify their functions, yet regional public archives has not been established. In this context, the concept of 'Larchiveum(libraries + archives + museums)' was proposed as an alternative that integrates and provides various information functions and resources, and research related to this started to emerge. At present, however, the Larchiveum has not been realized, the specific pathway to realize this kind of institution need to be discussed. This study analyzes the functional characteristics and elements of archives, libraries and museums, and based on these, the functional requirements of the larchiveum are drawn, and are reflected on the Larchiveum's functional planning for space planning in this study.

The main purpose of this study is to analyse and evaluate the metadata elements of 'Records System' and 'Electronic Document System' specifications for Korean government agencies based on functional requirements of ISO 15489. This present paper begins with discussing the characteristics of recordskeeping metada, and extract the metadata elements fulfilling the ISO 15489 functional requirements. And this study tries to compare the metadata elements of current specifications with ISO 15489 elements. Based on these analyses, it suggests the directions for improving current metadata specifications and for developing national metadata standard.

Security Policy Model is a structured representation using informal, semiformal or formal method of security policy to be enforced by TOE. It provides TOE to get an assurance to mitigate security flaws resulted from inconsistency between security functional requirements and functional specifications. Therefore, Security Policy Model has been required under an hish evaluation assurance level on an evaluation criteria such as ISO/IEC 15408(Common Criteria, CC). In this paper, we present an evaluation method for security policy model based on assurance requirements for security policy model in Common Criteria through an analysis of concepts, related researches and assurance requirements for security policy model.
