Purpose: To reinforce the product competitiveness of Korean small and medium-sized business in the world market. Methods: By clarifying the definition of a masterpiece, developing global masterpiece quality index(MQI) equipped with checklists, surveying several companies and customers, and analyzing the results of the survey via the MQ zone diagram. Results: The results of the survey show the gap between Korean small and medium-sized business and global masterpiece companies in terms of MQI. From this analysis, in order for the surveyed Korean companies to be the world-class ones, the managerial aspects to be improved could be clearly pointed out through the measurement indices. Conclusion: This research would provide Korean small and medium-sized companies, which wish to get on the global masterpiece level, with an objective guideline.

UML cannot meet all the requirements offered in different software system for diverse application domain. GNSS (Global Navigation Satellite System) application domain is an especial environment that requires precise measurement and precision calculation of real-world geographical entities with the help of GPS (Global Position System) in both temporal and spatial factor. Therefore in the paper new extended iconic stereotypes for better modeling GNSS application in the UML Diagram are proposed, and the implementation of a program called StereotypeCreator, which is able to create iconic stereotypes used in one of the most popular visual modeling tools for software development, Rational Rose, will be also proposed.

We present in this paper the methodology for automatic generation of OWL-S service model ontology along with the results and issues. First, we extract information related to atomic services and their properties such as IOPE from the UML class diagram, and retrieve information related to the composition of services from the UML state-chart diagram. Then, the XSLT applications utilize the acquired information to generate the OWL-S service model ontology through the predefined mappings between OWL-S constructs for composite services and UML state-chart primitives. For the justification of generated service ontology, several validation checks are performed. Our service ontology generation method is general and fully automatic, as well as effective, in that it is achieved in an environment familiar to developers, and information needed to generate service ontology is provided necessarily during service development. It is also noticeable to facilitate representing the condition with GUI rather than a complex language such as OCL.

This paper presents critical steps in building client/server application with UML and Visual Basic, which are derived from the implementation case of a typical order processing system. To begin with, we briefly review the software architecture, the diagrams and the object-oriened building process in the UML. In the inception phase, it is critical to define the project charter, to draw use case diagrams, and to construct a preliminary architecture of the application. In the elaboration phase, it is critical to identify classes to be displayed in the class diagram, to develop user interface prototypes for each use case, to construct sequence diagram for each use case, and finally to design an implementation architecture. Steps to construct implementation architecture are given. In the construction phase, it is critical to design both the database and components. Steps to design these components are described in detail. Additionally the way to create the Internet interface is suggested.

We propose the iconic animation of the software requirement specifications by using the object and dynamic models of the object modeling technique(OMT) methodology. In order to produce the iconic animation, we use "graphical classes" and "icon transformations." In general, the graphical classes are defined for each class of the object diagram. The icon transformations which show the activities of the application are constructed by considering the meaning of the activities and are defined by either basic or compound icons. The icon transformations are added to the state diagrams to generate extended state diagrams. The animation system generates the header files and the code instantiating GUI from the object diagram having graphical classes. The system also generates "event methods" from the extended state diagrams. When the event methods are executed, the behavior of the events is animated by the icon transformations.

본 연구는 UML(Unified Modeling Language) 표준에 의해 작성된 객체지향 다이어그램의 일관성과 정확성을 검증하는 방법에 관한 연구이다. 일관성은 하나의 요구사항으로 표현된 여러 가지 UML 다이어그램이 통일된 의미로 표현되었는가를 나타내는 성질이고, 정확성은 사용자가 작성한 다이어그램이 UML 표준에 적합하게 작성이 되었는가를 나타내는 성질이다. 정확성을 검증하기 위해서는 관계를 가지는 다이어그램들의 관계요소를 파악할 필요가 있다. 메타모델을 유도한 후에는 각 메타모델을 기초로 일관성 및 정확성 검증 규칙을 유도해 내고 검증의 자동화를 위하여 정형적 명세로 표현한다. 본 연구에서는 다이어그램별로 작성한 메타모델에서 규칙을 유도하고 그러한 규칙을 OCL(Obiect Constraint Language) 형태로 표현하여 검증하는 방법을 제안한다.

This paper presents a framework for analytical seismic vulnerability assessment of substandard reinforced concrete (RC) structures in developing countries. Amodified capacity-demand diagram method is used to predict the response of RC structures with degrading behaviour. A damage index based on period change is used to quantify the evolution of damage. To demonstrate the framework, a class of substandard RC buildings is examined. Abrupt accumulation of damage is observed due to the brittle failure modes and this is reflected in the developed vulnerability curves, which differ substantially from the curves of ductile structures.

본 논문에서는 대화형 시스템을 시험하기 위한 시험 사례를 마코프 연쇄의 통계적 확률 과정으로 생성하는 방안을 제시한다. 객체지향 방법론의 통합안인 UML에서는 클래스도(Class Diagram)가 표현할 수 없었던 시스템의 동적인 관점을 상태 전이도(State Transition Diagram)는 구체적으로 표현할 수 있다. 시스템의 사용법을 상태 전이도로 표현하고, 상태간의 전이 확률(Transition Probability)을 계산하여 사용법 연쇄(Usage Chain)를 구성한다. 사용법 연쇄는 다음 상태가 과거의 상태에 영향을 받지 않고 현시점의 상태에만 의존하는 이산 시간형 확률과정인 마코프 연쇄(Markov Chain)가 된다. 본 논문에서는 사용법 연쇄를 분석하여 상태 전이도의 상태와 원호가 어떤 범위에서 시험될 것인지 결정되었을 때, 사용법 연쇄의 전이 확률이 높은 순서별로 연결하여 시험 사례를 생성하는 방안을 제시하고, 예제를 설명한다.

This study aims to suggest an evaluation methodology of green-tourism potential for village level with amenity resources in rural areas. The amenity resources system was classified into three sub-classes(social, industrial, and natural/cultural/historical resources) and a relationship diagram between three classes and tourists' behavior was also defined. The methodology considers human resources in the village including the three sub-class amenity resources. The table and diagram were applied to make renewal plan for rural villages of the study area, Nami-myun, Keumsan-gun, Chungnam province, so that the development scheme for the villages was suggested reasonably by the new findings of this study.

XML이 웹에서 사용하는 문서와 데이터의 표준이 되고 있다. XML의 문서를 정의하는데 사용되는 것이 스키마다. 이 중 마이크로소프트사가 중심이 되어 개발하고 있는 스키마인 XDR은 스키마 중에서 실제적인 활용을 주도하고 있다. UML은 객체지향 개발 방법론에서 나온 표기법으로 시스템의 구조를 나타내는데 유용한 도구이다. 본 논문은 XDR의 스키마의 구조를 UML 클래스 다이어그램으로 변환하는 방법과 알고리즘을 제안한다. 이 변환으로 XML의 문서구조를 시각화하여 XML문서의 구조를 쉽게 파악할 수 있게 되었고 재사용성과 유연성을 높여 XML문서 개발을 효율적으로 하게 하였다.
