This paper suggests a method for developing computer code that can solve inverse heat conduction problem, The concept of the object-oriented development is employed to implement the computer code in an efficient and flexible fashion. The software design is conducted based on the unified modeling language. Furthermore, this paper also explains how to implement the deliverable computer code using the existing software development tools.

Manufacturing equipments should be integrated to construct CIM (Computer Integrated Manufacturing) environment, but several economical and technological difficulties may be arisen in case heterogeneous systems are integrated into each other. MMS (Manufacturing Message Specification) can be effective in such a case, but the problem is that MMS-related products are comparatively expensive and the existing manufacturing equipments mostly do not support MMS. This study was focused on developing a gateway suitable to a non-MMS-compatible CNC machine-tool, and on implementing OSI(Open System Interconnection) upper layer on TCP/IP. The development system was applied to a cell controller by means of heterogeneous equipments under CIM environment, and to evaluate interoperability and portability.

The Clustering is representative method of components classification. The previous clustering methods that use cohesion and coupling cannot be effective because design pattern has focused on relation between classes. In this paper, we classified design patterns with features of object-oriented relationship. The result is that classification by clustering showed higher precision than classification by facet. It is effective that design patterns are classified by automatic clustering algorithm. When patterns are retrieved in classification of design patterns, we can use to compare them because similar pattern is saved to same category. Also we can manage repository efficiently because of storing patterns with link information.

문화유산 정보 관리를 위한 참조온톨로지인 CIDOC Conceptual Reference Model(CRM)을 통해 관련 기관 간의 상호 협력 가능성이 증대되었으며, 서지레코드를 중심으로 개발된 FRBR 모형을 CRM을 기반으로 재구조화하여 통합한 FRBRoo 모형이 개발되었다. 본 연구에서는 FRBRoo 온톨로지를 분석하고 향후 적용방안을 도출하였는데, 그 결과 FRBRoo를 통해 문화유산 관리기관 간 정보의 교환과 통합을 위한 상호운용성 강화와 보다 확장된 추론 규칙을 설계할 수 있었다. 또한 통합의 부산물로써 FRBR과 CRM이 간과했던 정보 자원의 특징들을 새로운 시각으로 인식하고 개선할 수 있는 기회도 얻게 되었다.

A reference ontology for cultural heritage information, CIDOC Conceptual Reference Model (CRM), has promoted cooperation among memory institutions and FRBRoo, re-constructed version of FRBR based on CRM, was developed. In this study, the harmonized ontology version of FRBR, FRBRoo, was analysed and, as a results, the followings are suggested: empowered interoperability for information exchange and integration among cultural institutions and designing more comprehensible inference rules than original FRBR model. Moreover, the by-products of harmonization gave opportunity to recognize internal inconsistencies of the FRBR model and CRM itself and refine them.

Theory-wise, of course, much has been said and done already about Object Oriented Ontology (OOO). I will briefly discuss key issues revolving around OOO and how they might be relevant to reading Romantic works of art. I’m primarily concerned with demonstrating the conditions and instances of mediation between nonhuman objects working independently of human relevance and purposes in the pieces of works selected from William Wordsworth, Samuel Taylor Coleridge, P. B. Shelley and Henry David Thoreau. It’s part of a greater scheme to approach the world of lively things not particularly disadvantaged by anthropocentricism and human-oriented semiotic conventions. Noticeable topics include, but are not limited to: the ontic self-identity of things, lively matters, the ontological unity between humans and nonhumans, the ethics of things, and the art of attentiveness, all of which I think are crucial to make this planet a sustainable place.

The purpose of this paper is to examine the structural similarities between serial verbs and object-oriented depictive secondary predicates in agglutinative languages, such as Korean, Japanese and Turkish. In many serial verb languages, such as Korean, the first verb(V1) in V1-V2 constructions of simultaneous serial verb constructions usually express the manner of the V2 and the subevent denoted by V1 occurs simultaneously with the one denoted by V2. Similarly, the object-oriented depictive predicate denotes an event that occurs at the same time as the main verb and generally expresses the manner of the main verb. Moreover, Baker’s(1989) and Collins’(1997) internal argument-sharing hypothesis, which asserts that in a serial verb constructions, V1 and V2 must share an internal argument, also applies to object-oriented depictive constructions. We will demonstrate that these two constructions share some syntactic, semantic and prosodic characteristics. Based on an investigation of some serial verb languages, we conclude that object-oriented depictives form complex predicates with the verb, much like V1-V2 simultaneous serial verbs.

생산 시스템은 일반적으로 규모가 크고 복잡하며 동시 발생적인 특성을 가지는 경우가 많다. 이러한 특징은 시스템의 행태를 사전에 분석하고 시뮬레이션하기 위한 모델링에 많은 어려움을 가져오게 한다. 본 논문은 이러한 어려움을 해결하기 위하여 객체지향 페트리네트를 이용한 생산시스템 모델링 및 분석 도구를 제사한 것이다. 기본적인 구조는 페트리네트를 객체의 개념으로 구성하는 것이다. 객체의 개념으로 페트리네트를 구성하고 시스템의 행태는 객체간의 메시지 교환과 객체내의 행태로 표현된다. 시스템 분석에 있어서는 객체간의 메시지 전달관계와 객체내의 행태 분석 등이 가능하다. 대상 시스템이 객체의 클래스 개념으로 구성되기 때문에 복잡도가 많이 감소될 수 있다. 특히 본 논문에서는 상속성의 개념을 객체 지향 페트리네트에서 어떻게 구현할 것인가에 대한 방법과 분석 방법이 제시되었다.

DEM(Digital Elevation Model) 크기의 변화에 따라 특정 지역에 많은 규격의 수문 데이터가 존재할 수 있기 때문에, 어느 지역, 어느 기상 데이터에도 작동할 수 있는 수문 모형의 개발이 절실히 필요하게 되었다. 이와 같은 필요성을 설명하기 위해서 객체지향(object-oriented)적인 프로그래밍 기술을 적용한 GHISMO(Geographic and Hydrologic Information System Modeling Objects)라는 수문모형(hydrologic model)을 개발하였다. GHISMO의 가장 핵심적인 수문학적 접근방법은 저류-배출(storage-release)과 지표면 유효 강수량을 구하기 위하여 SCS curve number 방법을 사용한 것이다. 이 연구에서 수문모형의 모의실험 결과를 제공할 것이다.

With the availability of multi-scale hydrologic data in public domain depending on DEM size, there is a need for a modeling framework that is capable of using these data to simulate hydrologic processes at multiple scales for different topographic and climate conditions for distributed hydrologic model. To address this need, an object-oriented approach, called Geographic and Hydrologic Information System Modeling Objects (GHISMO), is developed. Main hydrologic approaches in GHISMO are storage-release for direct runoff and SCS curve number method for infiltration part. This paper presents conceptual and structural framework of storage-release concept including its application to two watersheds will be presented.

Also, the reverse analysis of game help us understand the technique to be used in game. Through this process, we introduce learning method enabling us to actively understand object-oriented concept. Thus, the proposed method describes case learning based on XNA game development environment, and presents a scenario according to role of teacher and learner.
