의료정보 교환을 위한 국제 표준인 HL7 메시지의 처리와 HL7의 다양한 버전 간 호환성 문제를 해결하기 위해 객체 지향적 구조에 기반한 HL7 파서(Parser)가 개발되었다. 그러나 개발된 파서를 의료정보시스템과 연동하여 사용하기 위해서는 의료분야 전문가와 소프트웨어 전문가의 협력이 필수적이다. 또한, 이들 전문가의 협업을 위해서는 각 분야의 전문지식에 대한 상호 이해가 전제되어야 하는데, 이를 위해서는 오랜 시간 상호간의 많은 노력이 필요한 과정이다. 따라서 본 연구에서는 버전 간 호환 가능한 HL7 파서를 기반으로 하여 HL7 메시지의 생성과 변환을 가능하게 하는 HL7 GUI 도구를 설계한다. 이를 통해, 컴퓨터 프로그래밍 언어에 익숙하지 않은 의료 분야의 전문가들도 HL7 GUI 도구를 통해 개념적으로 표현되는 그래프를 직접 디자인하여 의료정보시스템 간의 다양한 버전의 HL7 메시지를 처리하고 교환할 수 있는 환경을 제공한다.

Software reengineering is making various research for solutions against problem of maintain existing system. Reengineering has a meaning of development of softwares on existing systems through the reverse-engineering and the forward-engineering. It extracts classes from existing system's softwares to increase the comprehension of the system and enhance the maintenability of softwares. Most of the important concepts used in reengineering is composition that is restructuring of the existing objects from other components. The classes and clusters in storage have structural relationship with system's main components to reuse in the higher level. These are referenced as dynamic informations through structuring an architect for each of them. The classes are created by extractor, searcher and composer through representing existing object-oriented source code. Each of classes and clusters extract refined informations through optimization. New architecture is created from the cluster based on its classes' relationship in storage. This information can be used as an executable code later on. In this paper, we propose the tools, it presented by this thesis presents a new information to users through analysing, based on reengineering, Object-Oriented informations and practicing composition methodology. These composite classes will increase reusability and produce higher comprehension information to consist maintainability for existing codes.

Network management represents those activities which control and moitor the use of resources. Remote delegation model supports flexible and effective distribution of management functions among managers and agents, and it may cause an reliable network management in a relatively complex and high-speed networks. in this model, managers delegate to agents execution of management programs as prescribed in a management scripting language. In addition, primitives included in the management programs enable agents to monitor and control localmanaged objects effectively. We suggest management algorithms in which management scripts are delegated from managers to agents and partiality implement OSI fault management. This mans gement algorithm can effectively support delegation and control concurrent accesses to management information. Moreover, it can be easily translated into object-based concurrent programming language: ABCL. In this paper, we will scrutinize some essential aspects of this management.

This study is to suggest the bibliographic description of RDA & KCR4 cataloging rules for FRBRizing the aggregates based on aggregates modeling. It is to suggest bibliographic description of RDA & KCR4 cataloging rules of aggregates through analyzing FRBR and LRM aggregates modeling and comparing RDA and KCR4 cataloging rules about aggregates. First, it is to describe the bibliographic records based on object oriented model, and to describe both aggregates works and separate works appropriately. Second, in case of aggregates by one person, family, or corporate body, collective title as aggregates work and separate works in aggregates must be regulated in RDA. In KCR4, collective titles rules should be regulated for aggregate works and separate works should be described. Third, aggregates of works by different persons, families, or corporate bodies should be accessible by aggregates work and separate works, and aggregates of works by different persons, families, or corporate bodies without collective title should be accessible by each of the works in both RDA and KCR4. Fourth, augmentation aggregates could be accessible by main work's expression, the expression of aggregates work, and separate expressions of the augmentation. This study will contribute to FRBRize the aggregates by suggesting bibliographic description of RDA & KCR4 cataloging rules.

While various types of information can be mixed in a continuous video stream without any cleat boundary, the meaning of a video scene can be interpreted by multiple levels of abstraction, and its description can be varied among different users. Therefore, for the content-based retrieval in video data it is important for a user to be able to describe a scene flexibly while the description given by different users should be maintained consistently This paper proposes an effective way to represent the different types of video information in conventional database models such as the relational and object-oriented models. Flexibly defined attributes and their values are organized as tree-structured dictionaries while the description of video data is stored in a fixed database schema. We also introduce several browsing methods to assist a user. The dictionary browser simplifies the annotation process as well as the querying process of a user while the result browser can help a user analyze the results of a query in terms of various combinations of Query conditions.

With the development of the domestic character industry, the interest in public characters has also been increased as like the characters of industrial contents. The public character is a non-commercial character implicitly expressing the symbolism shared or directed by members of the specific region, organization, organization, organization, or event. It has been distinguished from commercial design, aiming the profit for a specific person or group, and it has been given the role coincided with the purpose of public design, pursuing social value such as citizens' happiness, happiness in the subject and object, aiming value and role of design. Public characters has been grown around the local government character development, but most of the characters were not practically utilized. However, as interest in public characters has been increased, those have been received worm welcome again as a means of expressing the uniqueness and identity of the region. In this paper, we have tried to study the expression of identity of public character by substituting the site-specificity. The site-specificity is referring the art of the time that focuses on the region in contemporary art, a work in which the meaning is created by a specific region and situation. Currently, as a main role of public character is representing the region or the institution, its identity and value can be judged by the community it belongs. Through this, it is intended to study the social meaning of the character in the region as a public design.

EDI is being considered as a new way for exchange business data in the form of electronic document, aiming the paperless transaction in business-to-business commerce. However, only a few enterprises select and practically use EDI accepts the closed and complicated method based on exclusive protocol for electronic document exchange. There, second, is insufficient regulation and system that support it. Last, the cost for operating is too high. In this paper, Open EDI Document Information Management System (OEIMS) was designed for solving the problem that mentioned above. We represented exchange document in code from as XML DTD. OEIMS that makers feasible to transfer their document through the web with low cost and, manage and search the information more efficiently and effectively using object-oriented database. We suggest OEIMS that provide efficiency to reposit and manage a system by modulized design of structural feature from EDI unlike other systems.

In order to develop high quality software, software metrics have been made to assess the quality of software, and recently, many object-oriented metrics have been suggested for this purpose as well. However, research on the utilization of metrics to control software quality in a development process has been inadequate. This is due to the difficulty in assessing the significance of metrics in a software development process from the perspective of overall software quality. In this paper, we propose a method of applying metrics to a development process using the Hierarchical Software Quality Model(H-SQM) which is defined in terms of the products' special features. The method represents the H-SQM as the cause-and-effect diagram and changes the diagram to the process-analysis diagram. And it applies software quality metrics to each development stage by the process-analysis diagram. In this way, we could utilize the software quality metrics efficiently in order to improve the quality of software in the software development process.
