In this paper, we implement the XML modeling and data modeling by the class diagram that is made by the use case after drawing out the sequence diagram. For the XML modeling, the guiding line to map the UML classes on the XML document will be presented. Then, an example to generate the ie DTD from the UML classes will be shown under the presented guiding line. In the data modeling, the transformation method from the In classes into the object-oriented database also will be proposed. Finally, we will give an example developed by the Proposed transformation method.

The quadrilateral analysis is a proportional analysis which evaluates the skeletal configuration of lower face on the relations between both jaws in the horizontal as we]1 as vortical dimensions. This study was undertaken to analyse the harmony and disharmony of quadrilateral patterns in normal occlusion and malocclusion. The present study was carried out on lateral cephalograms of 530 Korean children; the subjects consisted of 135 normal occlusions (63 male and 72 female), 105 Class II division 1 malocclusions (52 male and 53 female), 109 Class III malocclusions (50 male and 59 female), 91 hypodivergent facial types (44 male and 47 female) and 90 hyperdivergent facial types (45 male and 45 female). The following conclusions were reached: 1. Means and standard deviation in each group and sex were obtained from normal occlusion and malocclusion. 2. Quadrilateral mean diagram in normal occlusion was constructed for male and female, respectively. 3. In normal occlusion, 1:1 ratio exists between the maxillary base length (A' to Ptm') and mandibular base length (B' to J'), but lower facial height is targer than above. 4. Difference is effective to estimate the degrees of Class II and Class III malocclusion, and lower facial height (LFH) and sagittal angle is effective to recognize the hypodivergent and hyperdivergent facial type. 5. Quadrilateral analysis is able to visualize the anteroposterior and vertical dysplasia of lower face, and it is helpful to recognize certain problems in malocclusion.

According to the increase of organizational complexity and the change of rapid information technology environment, many firms have shifted their information technology(IT) strategy from developing information systems in-house to purchasing application software such as Enterprise Resource Planning(ERP) Systems. Marketing and Sales functions within a Korean automotive part company include developing new assembly products, determining pricing, taking customer's orders, and shipping assembly products to customers. Marketing and Sales Information System(MSIS) in ERP system plays an important role in next Production Planning process. MSIS also makes management reporting and decision making faster and more uniform throughout an organization. MSIS promotes thinking about corporate goals, as opposed to thinking only about the goals of a single department or functional area. This paper intends to design and implement a MSIS in ERP systems for Korean automotive part company using object-oriented methodology In order to accomplish the implementation of MSIS in ERP system, we employed UML as its standard modeling language. In this study, four diagramming techniques such as use case diagram, sequence diagram, class diagram, component diagram among eight modeling techniques are used for analyzing hierarchical business process. In traditional marketing and sales function, a company with an unintegrated information system can have marketing and sales data that is data redundant or inaccurate. MSIS integrated in ERP system can solve the sales forecast problem, which minimizes the total costs of production, inventory, and transportation under constraints of production capacity. Also, the use of UML methodology makes S/W programmers shorten the phase of analysis and design in the implementation of MSIS system, and increase the reuse of software and the interoperability with corporate internal Information system.

In order to design a system, software developers use an object model such as the UML class diagram. Object-Relational Transformation Methodology (ORTM) is a methodology to transform the relationships that are expressed in the object model into relational database tables, and it is applied for the implementation of the designed system. Previous ORTM studies have suggested a number of transformation methods to represent one relationship. However, there is an implementation problem that is difficult to apply because the usage criteria for each transformation method do not exist. Therefore, this paper proposes a binary decision diagram-based modeling rule for each relationship. Hence, we define the conditions for distinguishing the transformation methods. By measuring the query execution time, we also evaluate the modeling rules that are required for the verification. After evaluation, we re-define the final modeling rules which are represented by propositional logic, and show that our proposed modeling rules are useful for the implementation of the designed system through a case study.

It is possible to indicate the complex design and execution of object-oriented program with dynamic UML diagram. This paper shows the way how to make several test cases from sequence, state, and activity diagram among dynamic UML diagram. Three dynamic UML diagrams about withdrawal work of ATM simulation program are drawn. Then different test cases are created from these diagrams using previously described ways. To evaluate effectiveness of test cases, mutation testing is executed. Mutants are made from MuClipse plug-in tool based on Eclipse which supports many traditional and class mutation operators. Finally we've got the result of mutation testing and compare effectiveness of test cases, etc. Through this document, we've known some hints that how to choose the way of making test cases.

In this paper, we introduce a length function for elements of the imprimitive complex reflection group G(m, 1, n) and study its properties. Furthermore, we show that every conjugacy class of G(m, 1, n) can be represented by an admissible diagram. The corresponding results for Weyl groups are well known.

본 연구에서는 자바 코드로부터 UML 클래스 다이어그램을 추출하는 역공학방법을 제시하였다. 파서를 이용하여 자바 코드로부터 AST를 생성하고 이를 순회하면서 클래스다이어그램 생성에 필요한 정보를 추출하였다. 이를 위해 구조정보와 관계정보를 정의하였는데, 구조정보에서는 클래스 몸체를 구성하는 정보를 표현하였다. 관계정보에서는 클래스들 간의 연관관계를 결정하기 위해 필요한 정보를 표현하였으며, 얻어진 관계정보를 통해 연관관계를 유추하는 방법을 제시하였다. 특히 클래스들간의 연관관계를 추출하기 위한 규칙들을 정의하고, 이를 통해 얻어진 관계정보를 이용하여 연관관계를 유출하는 과정을 설명하였다.

In this paper, we realize the algebra of ${\mathbb{Z}}_2$ relations, signed partition algebras and partition algebras as tabular algebras and prove the cellularity of these algebras using the method of [2]. Using the results of Graham and Lehrer in [1], we give the modular representations of the algebra of ${\mathbb{Z}}_2$-relations, signed partition algebras and partition algebras.

최근 Workflow System의 컴퍼넌트화는 필수적인 것으로 인식되고 잇다. 컴퍼넌트화의 장점으로는 유지, 보수의 용이성과 다른 어플리케이션과의 원활한 통합을 들 수 있고, 컴퍼넌트 기반의 Workflow System은 e-business infra를 형성하는데 필수적이다. 따라서 본 연구에서는 기업 내부의 포로세스를 관리해 주는 Workflow System을 컴퍼넌트형태로 설계하여 가장 진보된 형태의 Workflow System의 기반을 마련한다. 본 논문에서는 RUP방법론에 다라 use case분석, class diagram분석을 통해서 DISFlow(Daewoo Information Workflow)를 EJB Architecture에 맞게 변환하였다.

최근 XML 문서가 급증함에 따라 웹-기반 XML 응용 문서의 중요성이 많이 부각되고 있는 실정이다. 웹-기반 XML 응용 문서 중 대표적인 예로 OSD가 있다. OSD는 소프트웨어 패키지와 그들 간의 관계를 정의하는 것이다. UML은 객체지향 표준 모델링 방법으로 객체지향 코드 생성이나 데이터베이스 스키마 생성을 용이하게 해주는 표기법이다. 따라서, 본 연구는 XMI를 이용하여 OSD로 부터 UML 클래스 다이어그램을 생성하는 시스템을 구현한다. 본 연구의 의의는 향후 늘어나는 웹 기반 XML 응용인 OSD의 표준 모델링 방법을 제안함으로써 객체지향 문서 관리의 기반이 되도록 한다.
