Increasing product variety based on product family and product platform provides a company with a competitive advantage over its competitors. As products become more complex, short-life cycled and customized, the design efforts require more knowledge-intensive, collaborative and coordinating efforts for information sharing. By sharing knowledge, information, component and process across different families of products, the product realization process will be more efficient, cost-effective and quick-responsive. Formal Concept Analysis (FCA) is used for analyzing data and forming semantic structures that are formal abstractions of concepts of human thoughts. A Web Ontology Language (OWL) is designed for applications that need to process the content of information instead of simply presenting information to humans. OWL also captures the evolution of different components of the product family. The purpose of this paper is to develop product variety modeling to increase the usefulness of common platform. In constructing and analyzing product ontology, FCA is adopted for conceptual knowledge processing. For the selected product family, product variety Ontology is constructed and implemented using prot$\'{e}$g$\'{e}$-2000.

The ebXML (Electronic Business using eXtensible Markup Language) Specification Schema is to provide nominal set of specification elements necessary to specify a collaboration between business partners based on XML. As a part of ebXML Specification Schema, BPSS (Business Process Specification Schema) has been provided to support the direct specification of the set of elements required to configure a runtime system in order to execute a set of ebXML business transactions. The BPSS is available in two stand-alone representations, a UML version and an XML version. Due to the limitations of UML notations and XML syntax, however, current ebXML BPSS specification is insufficient to specify formal semantic constraints of modeling elements completely. In this study, we propose a classification schema for the BPSS semantic constraints and describe how to represent those semantic constraints formally using OCL (Object Constraint Language). As a way to verify a Business Process Specification (BPS) with the formal semantic constraint modeling, we suggest a rule-based approach to represent the formal constraints and to use the rule-based constraints specification to verify BPSs in a CLIPS prototype implementation.

This paper presents a formalism-based methodology and its implemented environment which constitutes a sound framework for real-time systems development. The software and/or hardware systems developed in such a formal manner are well structured and maintainable. We first propose a set-theoretic VSSS (Variable Structure System Specification) formalism. This formalism is the core of the presented methodology which supports a means of formal specification for real-time systems. We then develop the environment, including VSSS language definition, a translator for the language, and supporting libraries for real-time execution. Finally, a demonstration of the methodology in development of a real-time event manager, a subsystem of an ATM-based communication system, shows the correctness and efficiency of the methodology.

Unit testing which is the first task to perform software testing has a major impact on reducing s/w development cost and improving s/w quality. In order to make unit testing become the formal procedure rather than ad-hoc tasks performed by developer, the language-neutral measures are necessary in the programming which is able to specify the test cases. This paper presents a test assertion language for the language-neutral specification of the test cases. The suggested language is based on the ISO/IEC 24709-1, but it supports object oriented features and can describe test cases for unit testing. The test cases that are specified by the language can be used for generating test oracle source codes by test oracle generation tools.

SMIL(Synchronized Multimedia Integration Language)는 멀티미디어 객체의 집합으로 시간적인 동기화를 표현할 수 있는 마크업 언어이다. 본 연구에서는 SMIL 문서를 시간에 따라 동기화 표현을 명확히 할 수 있도록 객체 지향 기반의 시각화 도구인 UML의 사용 사례(Use case), 순서(Sequence), 다이어그램을 이용한 객체 모델링 방법을 제안한다. 이를 위해 SMIL 문서에서 UML 사용사례와 순서 다이어그램으로의 사상 규칙과 알고리즘, 형식 모델, 그리고, 모델링 함수를 제안한다. 본 연구의 의의는 SMIL 문서 개발자들이 손쉽게 문서 구조 파악 및 개발을 할 수 있으며, 형식 모델과 다이어그램 모델링 함수는 객체지향 데이타베이스 문서 관리의 기반이 된다는 것이다.

VOQL* query language, recently proposed, is a visual language for object-oriented databases. It is based on Ven Diagram and graph, so that the underlying schema structure can be naturally implied in query expressions. In VOQL*, structural relationship among the objects used in a query expression is represented graphically and thus it has formal semantics that can be inductively defined, as well as it can be used with ease. In this paper, we proposed revised VOQL* and introduced its query processor, InQs(Intelligent Querying System). While retaining the merit of VOQL* that it allows the structural relationship among the objects to be represented visually, the revised VOQL* has another merit that users can formulate a query interactively using various forms supplied by InQs. As a query processor that translates queries in revised VOQL into those in ODMG OQL, InQs provides an environment in which users express queries in revised VOQL* and then the system automatically translates them into those in ODMG OQL. Translation algorithm of InQs is much simpler and intuitive than other algorithms used in QUIVER and other systems, since it reflects the formal semantics of VOQL*, which is defined inductively.

This paper examines the way in which the idea of language has been introduced in architectural discourse since the late 1960s. The paper reviews the works of Robert Venturi, Charles Jencks, Peter Eisenman, Alan Colquhoun, and Mario Gandelsonas, which explore the analogy between linguistic and architectural form. All of the writers above are responsive to each other's theoretical positions, sometimes implicitly and sometimes explicitly. A system of signs can be approached by asking how the lexicon and syntax are proportioned. The same question may be posed to architecture: can architecture be understood as a lexicon or as a relational structure, such as language is\ulcorner Two perspectives are presented by architectural theorists. The first advocated by Venturi and Jencks posit architectural form as a problem of signs. The problem with this perspective is that, it reduces architecture into popularized iconography in favor of the representational aspects of architectural form. The second perspective, developed by Eisenman, explores the possibility of finding new formal constructs in the abstract relationship of formal properties. Eisenman's theory, however, has its own problems for, in highlighting syntactic structure, it minimizes the distinction between the perceptual and the pragmatic dimensions. Yet both perspectives address crucial problems of contemporary architecture and expand architectural discourse into the broader realm of humanistic studies.

웹서비스 기술의 활성화와 더불어, XML 문서에 대한 접근통제기술이 새롭게 개발되었다. 그 결과, 기존의 접근통제시스템에서와 마찬가지로, 중요정보 자원에 대한 접근통제문제에 대한 연구가 큰 각광을 받고 있다. 본 논문에서는 XML 문서에 대한 접근통제정책을 정형명세언어인 CSP로 변환하는 방법을 제시한다. 이를 위해, 첫째, XPath 경로지정 언어로 표현된 XML 문서의 계층적 접근을 CSP 프로세스 알제브라로 변환하는 방법을 소개한다. 둘째, XML 스키마 문서를 오토마타 형태의 정형모델로 표현하는 방법을 설명한다. 셋째, XML 접근통제정책에 사용되는 적용 규칙 및 충돌규칙의 의미론을 프로세스 알제브라 언어로 표현하는 방법을 제시한다. 마지막으로, 본 논문에서 제시한 방법론의 타당성을 보이기 위해, XML 스키마 문서 및 경로지정 표현에 대한 CSP 명세 예제를 보여준다.

분산 객체 시스템에서 보안 기술과 객체지향 기술의 통합은 중요한 요소이기 때문에 OMG(Object Management Group)에서는 객체 시스템에서 보안성을 다루기 위한 표준 보안 서비스 규격으로 CORBA(Common Object Request Broker Architecture) 보안 참조 모델(security reference model)을 제시하였다. CORBA 보안 참조 모델에서 접근 제어 기능은 특정 구현 메카니즘에 종속되지 않는 독립적인 개념으로 정의되고 있으며, 또한 보안 특성의 의미가 완전하게 기술되지 않는다. 이는 구현자와 사용자가 상호 일치되지 않은 개념을 갖을 가능성을 내포한다 따라서 본 논문에서는 CORBA 보안참조 모델에 기술된 접근 제어 기능이 갖는 의미가 정확히 기술될 수 있도록 집합론에 기초하는 정형화 언어인 Z 언어의 스키마 구조를 이용하여 CORBA 접근 제어 모델을 정형화한다.
