This paper has been designed extend object-orientid database model that introducted new class basing the Heurilistic Classfication model. In order to implement this model, we have introducted heurilistic class to traditional object-orinted database. And we designed querry for search data that basis on the heurilistic classficasion model using stored data in extened object-oriend data model.

In this paper, the multi-stage radius-directed algorithm is applied to fractionally spaced equalizers which are insensitive to the sampling timing-phase. these equalizers exhibit good convergence characeristics when compared to fractionally spaced blind equalizers using conventional blind algorithms. Also, multi-model fractionally spaced blind equalizers, which use multiple symbol spaced blind equalizers that operate independently, converge faster than conventional fractionally spaced blind equalizers.

본 연구는 방사선사가 인지하는 조직문화와 셀프리더십 유형을 살펴보고, 조직유효성에 영향을 미치는 관련요인을 분석하였다. 셀프리더십의 전체 평균은 5점척도에 3.35점이었,다. 셀프리더십의 자기목표설정과 조직문화의 관계지향적요인은 조직몰입과 직무만족에 모두 관련이 있었다. 조직몰입은 근무지, 조직문화의 위계지향적, 관계지향적 요인이 26.8%의 설명력으로, 직무만족은 기혼자, 셀프리더십의 자기목표 및 자기관찰, 관계지향적 조직문화 요인이 41.6%의 설명력으로 나타났다. 조직의 성과를 높일 수 있는 조직문화를 형성해 나가는 방안의 모색이 필요 할 것이다.

As the importance of software measurement increases, there are more researches developing the new software measure. Given the importance of object-oriented development techniques, one specific area where this has occurred is coupling measurement in object-oriented systems. This thesis presents the coupling measure COM based on the methods and OOC based on the classes in measuring the coupling of object-oriented systems. And, it evaluates them using the coupling properties suggested by Briand while it compares them with other coupling measures by applying them to a system developed in the language of C++programming language.

XML is being accepted as a standard for the next generation web documents, as it enables to extend the document structures. However, general users have difficulties in writing valid and well-formed XML documents, since the documents should satisfy the grammatical constraints of XML. In this paper, we present a syntax-directed XML document editor which will ease users in writing valid XML documents. The editor will help users, and increase productivity in writing XML documents.

Electronic socuments described in SGML DTD are effedtive to manage with the object-oriented database. To do that,first of all, a database design for SGML documents must be preceeded. In this paper, we suggest an object-oriented meta schema for managing SGML DTDs, which describes logical structures of electrinic socuments. We also propose a method a methof to manage electronic documents in object-oriented databases through the application database schema which is synamically create from the meta schema.

Satellite structure is distorted by thermal load in orbit. The structural distortion induces the pointing errors of observation unit that is difference between initial pointing direction at ground integration and at in-orbit. In that case, satellite is not able to point along required direction. As observation capability becomes higher, structural distortion due to thermal load should be smaller to achieve successful mission. In this paper, the method to predict pointing error and results are described.

객체 지향 설계를 재구조화하기 위해서는 메소드와 속성들 사이의 관계를 파악해야 한다. 메소드와 속성들이 동일한 클래스에 속하는지를 추론하는 과정은 클래스 자료 참조 분석과 메소드 호출 분석에 의존한다. 최근의 많은 소프트웨어들은 규모가 방대하고 복잡하여 개발자가 도구를 사용하지 않고 수작업으로 설계를 재구조화기 어려우며 또한 너무 많은 시간과 노력이 요구된다. 본 논문에서는 메트릭을 이용하여 객체 지향 설계를 자동적으로 재구조화하는 방법을 기술한다. 먼저 메소드, 속성, 클래스, 그리고 그들의 관계츨 추상화된 모델로 표시한다. 이 모델을 기반으로 객체 지향 설계를 정량적으로 측정할 응집도와 결합도 메트릭을 정의한다. 본 논문의 메크릭은 재고조화 과정 동안에 여러 다른 설계들을 효율적으로 비교하기 위한 유용한 기준을 제공한다. 기본 재구조화 행위들과 그 의미(semantics)를 정의하고 메트릭과 행위들을 사용하여 설계를 자동적으로 재구조화한다.

The purpose of this study was to investigate orientation toward teaching of science teachers had shown in lesson on Law of Definite Composition for middle school students and the factors which influenced its formation. To achieve this, we collected survey materials by recording and analyzing lessons of 8 teachers, interviewing them, and using CoRe questionnaire. From teachers' activities in lessons, we found their orientation toward science teaching, and through analyzing collected materials, drew the factors which influenced the formation of orientation toward science teaching. The result identified two types of orientation toward science teaching: activity-directional and lecture-directional. The former, activity-directional was categorized further as exploration and non-exploration; the latter as interaction-centered and content delivery. The main factors which affected the formation of orientation toward science teaching were reflective thinking through teaching experiences, interaction with colleagues, consideration on education environment, training as a learner, and their own interest and curiosity. Among them, the reflective thinking through teaching experiences was strongest cause, and teacher's interest and curiosity was even limited, also influenced positively. On the other hand, unlikely other factors, consideration on education setting affected negatively to build teacher's teaching orientation. Interaction with colleagues, training for teachers by universities and graduated schools acted on a bit, but had a limit just for mainly developing science content knowledge.
