Computer Aided Software Engineering(CASE) tools are suggested as an automated method for the efficient development of softwares. This study are intended to measure the use level of CASE tools and to provide the meaningful information on the whole software development environment supported by CASE tools. Therefore, the results of a survey on CASE environment in Korea are empirically reported and analyzed. The use of CASE tools is measured; purposes purchasing CASE tools and achievement levels are investigated. Implications from the comparative analysis of the utilization of software engineering methodologies between the CASE user group and the non-user group are described. A proposition is suggested to check the request frequency for program change. Further studies on the reverse engineering, program reuse and the use of CASE tools under distributed processing systems such as client-server environments are suggested.

CASE tools are complex software products offering many different features. Systems professionals have evaluated various CASE products from a feature and attribute basis. Each product has a different mix of strengths and weaknesses as perceived by the end user. Specific CASE tools support different steps of the applications development process as well as varying methodologies. In this paper we develop a method for evaluating CASE tools. The model has an analytic hierarchy process for evaluating CASE tools in terms of functionality, management efficiency, and support ability of provider, and a data envelopment analysis for overall evaluation considering cost and AHP results. We applied the developed model to a real world case study.

The diversity of students is getting increased in the contemporary classroom. To deal with the diversity, differentiated instruction (DI) should be considered as a way of providing alternative approaches to content, process and product according to the students' readiness, interest, and learning needs. Teachers have problems and difficulties in supporting different student's needs. In fact, teachers need proven tools including framework, guidelines or computing systems to help to practice DI in real context. According to the activity theory, tools influence on how people act and think and even their social practice, playing a crucial role in mediating the activities with people. In DI practice, there are also some studies about physical and abstract tools, but they have been not widely utilized by teachers in real schools. It means that more innovative tool to promote DI might be required. Therefore, to design a better tool to mediate the DI activities with teacher, case studies were conducted. In order to elicit the design implications, two physical and two abstract tools for DI practice were analyzed as case studies. Through the analysis of the case studies, eight design implications better to facilitate DI practice were suggested. This study has implications in suggesting design guidelines for teachers' tools to facilitate their DI practice by analyzing case studies in DI practices for an innovative tool in the educational practice.

Most of enterprises depend on a data modeler during developing their management information systems. In formulating business requirements for information systems, they widely and naturally use the interview method between a data modeler and a field worker. But, the discrepancy between both parties would certainly cause information loss and distortion that lead to let the systems not faithful to real business works. To improve or avoid modeler-dependant data modeling process, many automated data design CASE tools have been introduced. However, since most of traditional CASE tools just support drawing works for conceptual data design, a data modeler could not generate an ERD faithful to real business works and a user could not use them without any knowledge on database. Although some CASE tools supported conceptual data design, they still required too much preliminary database knowledge for a user. Against these traditional CASE tools, we proposed a Requirement-Oriented Entity Relationship Model for automated data design tool, called ROERM. Based on Non-Stop Methodology, ROERM adopts inner systematic modules for complete and sound ERD that is faithful to real field works, where modules are composed of interaction modules with a user, rules of schema operations and sentence translations. In addition to structure design of ROERM, we also devise detailed algorithms and perform an experiment for a case study.

Focusing on a product, this paper reconstructs the concept of technological systems first introduced by Carlsson and Stankiewicz (1991). Based on the model and our earlier works, we compare the salient features of technological systems for computer numerically controlled (CNC) machine tools in Korea, Sweden, and the United States.. We also try to measure the performance of the systems in an international comparison. Major findings are as follows: (1) The length of 'learning period' for local (national) technological system is substantial, even though it is a catching-up case. (2) The key success factor of the technological system appears to be the connectivity among various actors or infrastructures, rather than just the existence or formation of those. (3) In three countries' experience, the government played an important role in the formation of each own technological system. (4) The performance of Korea's technological system for CNC machine tools during the past two decades(1981-97) seems to be better than that of Sweden and the U.S. Lastly, many policy implication are presented.

미국의 전자산업협회(Electronic Industries Association)에서는 1991년부터 CASE 도구간의 정보교환을 용이하게 하기 위하여 CDIF (CASE Data Interchange Format) 이라는 표준 형식을 제정해 오고 있다. 각 CASE 도구에서 사용된 데이터를 CDIF 형식으로 변환만 해주면 다른 CASE 도구에서 이를 자신에 맞는 형식으로 변환하여 사용할 수 있다. 이때 각 CASE 도구 공급자는 CDIF 형식으로 변환 혹은 CDIF 형식을 자신에 적합한 형식으로 변환하는 프로그램을 작성하여야 한다. 본 논문에서는 이러한 불편을 해소하기 위해서 CASE 도구 공급자가 각 CASE 도구에서 사용된 자료의 저장형식을 지정하여 주면 CDIF 형식을 지원하는 변환기의 소스코드를 자동으로 생성하는 생성기를 개발하였다. 이 자동 생성기는 CASE 도구에서 사용된 자료의 저장형식, 저장형식에 대한 메타정보, CDIF 메타정보를 입력받아서 CDIF 문장을 생성한다. 본 연구에서 개발한 자동 생성기는 정보저장소에 관계없이 단일화된 인터페이스를 제공하는 JDBC 및 Oracle과 Sun O/S 환경하에서 구현하였다.
