Although some CASE tools supported conceptual data design, they required for users too much preliminary knowledge to learn how to use and handle them. In addition, in a number of studies on conceptual data design with natural language, they claimed passive participation for users with conforming to messages predefined by CASE tools. As an alternative to these traditional CASE tools, we proposed an ERD formulator for automated data design tool, called ERDF, so that even ordinary users, not necessarily data modeler, are capable of formulating ERD on business requirements by use of ERDF. We, first of all, introduced NSM as the standard methodology. We also designed the structure of ERDF including main controller, input controller, operation controller, regulation controller, schema controller, and output controller. We then defined conceptual domains and basic operations to lay down schema operations as well as sentence rules to handle input sentence in natural language. To get an ERD that is faithful to business requirements, we laid out supplementary design for dialogue and confirmation of soundness and completion.

본 논문은 Use Case 기반 개발에서 요구사항부터 테스트 케이스를 자동 추출하는 메커니즘을 제안 하고자 한다. 제안한 메커니즘은 기존의 테스트케이스 생성 메커니즘을 Use Case 메커니즘과 접목한 것이다. 그리고 그 기반으로 자동 도구 구현을 통해 모든 가능한 테스트 케이스 추출하는데 있다. 이는 최소의 테스트 케이스로 100%의 기능적인 요구사항 커버리지 만족시킨다는 Gary 방법을 이용하고자 함이다. 이 도구의 단계는 확장된 UML 다이어그램으로부터 원인-결과 다이어그램을 전환 한 후, 결정 테이블화한다. 마지막 단계는 이를 통하여 테스트케이스가 자동적으로 발생 한다.

This research is intended to analyze the tendency and mixed-use of the PFI for the middle schools in Chiba Province, Japan. The Ichikawa 7th middle school has included food supply system, nursery school, auditorium, day service center and care house. It consists of 2 PFIs. The one is middle school, food supply system, nursery school and Auditorium. The other is Day Service Center and Care House for elderly. This is the first mixed-use school by PFI in Japan. The PFI is a very nice tool for the future of our educational environment. But it has weak points, too. This paper analyze the case of Japanese PFI for the better results of Korean BTL systems.

Many Swedish health care organizations have during the last decade started implementing the Balanced Scorecard (BSC) as a systematic way of following-up and analyzing their activities. However, the knowledge of its use and contribution in a health care context is insufficient. Based on a multiple case study the authors explore the use of the BSC in the Swedish health care services. The authors conclude that the concept in a health care context is used as a quality management tool that make new demands on management. In addition, the authors bring out important factors for a long-term use of the BSC.

This study uses a hybrid estimation tool for effective cost data management of building projects, and develops a realistic cost estimation model. The method makes use of newly available information as the project progresses, and project cost and percentage progress are analyzed and used as inputs for the developed system. For model development, case-based reasoning (CBR) is proposed, as it enables complex nonlinear mapping. This study also investigates analytic hierarchy process (AHP) for weight generation and applies them to a real project case. Real case studies are used to demonstrate and validate the benefits of the proposed approach. By using this method, an evaluation of actual project performance can be developed that appropriately considers the natural variability of construction costs.

Electronic Industries Association has set a standard format called CDIF(CASE Data Interchange Format) for exchanging information between CASE tools from 1991. If data used on a CASE tool is represented in CDIF format, then any other CASE tools can use the data by translating CDlF format into their own format. In order to do so, each CASE vendor must provide a translator program from CDIF to its own data format or from its own data to CDIF format. In this thesis, we have implemented a source code generator for translating CASE data format into CDIF format only if they provide how data is stored. This automatic program generator generates CDIF statements using data format used in CASE tools, meta information about stored data and CDIF meta information. In the thesis, the automatic program generator has been implemented with Java and Oracle DBMS with JOBC interface in Sun O/S environment.

One of the traditional optical methods to monitor a tool is a CCD sensor-based vision system which captures an aspect of the tool in real time. In the case using the CCD sensor, specific lens-modules are necessary to monitor the tool with higher resolution than its pixel size, and a microprocessor is required to attain desired data from captured images. Thus theses additional devices make the entire measurement system complex. Another method is to use a pair of an optical source and a detector per measuring axis. Since the method is based on the intensity modulation, the structure of the measurement system is simper than the CCD sensor-based vision system. However, in the case measuring the three dimensional position of the tool, it is difficult to apply to micro machine-tools because there may not be space to integrate three pairs of an optical source and a detector. In this paper, in order to develop a tool-origin measurement system which is employed in micro machine-tools, the improved method to measure a tool origin in x, y and z axes is introduced. The method is based on the intensity modulation and employs one pair of an optical source radiating divergent beams and a quadrant photodiode to detect a three dimensional position of the tool. This paper presents the measurement models of the proposed tool-origin sensor. The models were verified experimentally The verification results show that the proposed method is possible and the induced models are available for design.

The major concern of component users who develop applications using the existing components is to confirm whether a component is collaborating with the different components in accordance with the requirements. Therefore, interoperability testing whose role is to check whether components collaborate with each other within the new operating environment not within the component development content of each component is considered as an importance research topic. In this paper, we propose a test case generation technique for interoperability test of component based software. The proposed technique defines a test model for generating test cases. The proposed technique generates test models from the use case specification and thereafter from these models, test cases for Interoperability testing are derived. In addition, we describe a tool which Implements the procedures for generating test sequences from test models.

SMIL(Synchronized Multimedia Integration Language) allows multimedia objects into a synchronized multimedia presentation. In this paper, I propose modeling rules, formal models, modeling function and an algorithm for SMIL documents using use case diagram and sequence diagram of UML(Unified Modeling Language)to Develop for SMIL Documents Editor. It will be used the use case diagram and collaboration diagram for object-oriented visualizing tool to describe the temporal behavior of the presentation. The main contribution of this paper is that developers of SMIL documents editor easily generate them using this rules and algorithm. And, the formal models and modeling functions provide an environment for processing object-oriented. documents.
