A computer program for matrix structural analysis by object-oriented programming technique using $C^{++}$ language has been developed. Object, class, method and inheritance which are used in object-oriented programming are illustrated using a graphical representation. The matrix operations and the structural analysis by matrix displacement method were satisfactorily performed by the proposed program. Numerical tests demonstrate that this proposed program can be widely used for the matrix structural analysis for personal computers.s.

Recently, object-oriented concepts and technology are on the leading edge of programming language and database systems research, and their usefulness in those contexts has been successfully demonstrated. The adoption of object-oriented concept to the design of model bases has several benefits. From the perspectives of object-oriented approach, models in a model base are viewed as object which encapsulate their states and behaviors. This paper focuses on the design of an object-oriented model base that handles various resources of DSS(data, knowledge, models, solvers) in a unified fashion. For the design of a model base, we adopted Object Modeling Techniques(OMT). An object model of OMT can be used for the conceptual design of an overall model base schema. The object model of OMT provides several advantages over the conventional approaches in model base design. The main advantage are model reuse, hierarchical model construction, model sharing, meta-modeling, and unified model object management.

데이터베이스에 대한 제약사항들은 소프트웨어의 개발 및 사용에 있어 개발자와 사용자가 모두 참고해야 하는 중요한 사항임에도 불구하고 데이터베이스 모델링괴 소프트웨어 모델링의 불일치 및 표현 방법의 차이로 인해, 일관성 있는 제약사항 명세 및 설계에 많은 어려움을 겪어왔다. OCL(Object Constraint Language)은 객체의 제약사항을 표현하는 언어로서 UML(Unified Modeling Language)의 일부분이다. 본 논문은 객체의 제악사항을 표현하는데 사용하던 OCL을 데이터베이스의 제악사항을 설계에 일관성 있게 표현, 반영하기 위하여 사용하는 기법을 제시하고, 이에 대한 검증을 수행하는 방법에 대한 연구이다. 본 논문에서는 요구사항에서 추출한 데이터베이스의 제악사항을 정의한 규칙에 따라 추출해내고, 이를 OCL의 표현법을 이용하여 정형적으로 표현한다. 그리고 그 OCL의 형식적 표현을 ODL(Object Description Language)로 정의하는 기법을 정의함으로서 이에 대한 일관성 검증을 수행하는 기법을 제안한다.

XML (extensible Markup Language) is a flexible way to create common information formats and share both the format and the data on the World Wide Web, intranets, and elsewhere. A document type definition (DTD) is a specific definition of the rules of the Standard Generalized Markup Language. A relational database management system (RDBMS) is a program that lets you create, update, and administer a relational database. An RDBMS takes Structured Query Language (SQL) statements entered by a user or contained in an application program and creates, updates, or provides access to the database. This paper has been studied a method of mappings from XML DTD to RDB schemas based on object model.

Semantics-based notations need to be used for specification of static and dynamic semantics to specify and implement new programming language. If the semantics is practically defined, we easily gain a translator according to the implementation of the semantics. In this paper, we describe the static and dynamic semantics to get a translator easily. We present practical semantics-based Action Equations, an extension and transformation of Attribute Grammar(AGs) suitable for specifying the static and dynamic semantics of a object oriented programming language. Compare with the existing descriptions, Action Equations is superior, modernized, and accurate.

This paper presents an application of Unified Modeling Language(UML) software technique for developing transmission pricing evaluation package. Also, this paper describes a transmission pricing algorithm applicable to a large-scale power system. The usage-based transmission pricing mechanism is very complex since it requires power flow analysis, fault current analysis, sensitivity evaluation of a transmission line, penalty factors calculation, transmission asset databases, and cost allocation rules, etc. For the efficient and flexible development of the transmission pricing package, a UML. approach is applied, which is composed of a use-case diagram, interaction diagram, class diagram, and package diagram using Rational Rose Unified Process(RUP). The designed transmission pricing package can be efficiently modified and reused as the market environments evolves since it is designed by Object-Oriented Programming(OOP).

This paper investigates syntactic variations in English such as Dative Alternation, Particle Inversion, and Object Postposition (Heavy NP Shift) within the framework of Optimality Theory, and shows that the same set of morphological, informational, and processing constraints affect all these variations. In particular, it shows that the variants that used to be regarded as ungrammatical are in fact used fairly often in reality, especially when processing or informational conditions are met, and therefore, grammatical judgment may not be always categorical but sometimes gradient. It is argued that the notion of distance in constraint ranking in stochastic OT can effectively explain the gradience and variability of grammaticality in the variation phenomena.

In this paper, an English-Korean machine translation system which consists of a syntax analyzer, a semartic analyzer and a sentence generatodr is proposed. The intermediate language in the syntax analysis is described by a lambda categorial grammar that is based on Montague Grammar, and the augmented context free grammar is introduced in the description of object language. Much difficulty in constructing general rules and semantic representations of an object language in the parser can be avoided by using the knowledge from the user interface utility that can modify the contents of dictionary and grammar rules.

Currently, generative artificial intelligence is a hot topic around the world. Generative artificial intelligence creates various images, art, video clips, advertisements, etc. The problem is that it is very difficult to verify the internal work of artificial intelligence. As a requirements engineer, I attempt to create a toon image by applying linguistic mechanisms to the current issue. This is combined with the UML object model through the semantic role analysis technique of linguists Chomsky and Fillmore. Then, the derived properties are linked to the toon creation template. This is to ensure productivity based on reusability rather than creativity in toon engineering. In the future, we plan to increase toon image productivity by incorporating software development processes and reusability.

The present code generation system, developing based on single system, Is not easy for developers or maintenance men to share pattern design information in distribution environment. So in this paper, we design and implement XML as basis of web environment, and JiKU/XML object-oriented code generator using pattern design. We use UML to change pattern design to XML code, and create code, suitable to PIML command, to generate design information designed by UML into XML code. This JiKU/XML Object-oriented Code Generator makes 10-step codes, and can be easily applied to web environment. It complements the disadvantage of present generator, F77/J++, and makes standardization of design because it uses UML and design pattern information. We compare it with present system by implement Eases, and as a result, generator suggested in this study gives more effective function.
