In this research, we show that constructing a specific job-processing-sequences like a OPL paragraph in OPM (we call it int a new terminology 'program', which just means plan) is essential step in programming, just like a blueprint for a wood furniture or a house. As a result of our research on how to produce a specific job-processing-sequences without OPM, we found that outlining tool is the most easy-to-use tool for the required job. We show that the MS-word outlining function can be used easily as a good programming supporting tool with Visual Studio C/C++.

그동안 우리는 분산응용을 구성하는 자원들을 하나의 논리적인 그룹으로 관리하기 위한 연구를 수행하여 분산객체그룹 프레임워크(Distributed Object Group Framework, DOGF)를 구축하였다. 또한 DOGF 기반에서 분산응용의 복잡한 개발절차를 최소화하고, 이전에 개발된 분산자원들의 재사용성을 효율적으로 제고할 수 있는 분산프로그램 개발도구인 DPD-Tool(Distributed Programming Developing Tool)을 개발하였다. 본 논문에서는 우리가 개발한 GUI 지원 DPD-Tool을 이용한 분산응용의 개발 편리성과 DOGF가 지원하는 그룹관리 분산서비스의 수행성을 검증한다. 이를 위해 GUI 기반에서 분산응용의 예를 들어 서버와 클라이언트 측의 개발절차를 제시하며, 이로부터 DPD-Tool이 DOGF의 지원 서비스를 통하여 그룹화 분산응용 내 중복자원들을 효율적으로 이용하는지 그 수행결과를 확인한다.

As software industry is rapidly evolving, IT business enterprises have been meeting with cutthroat competition in developing software. As software reusability, time to market, and maintainability are considered as a competitive edge, software component techniques have lately attracted considerable attention. Currently, although there are some supporting tools for developing software components, they do not have tight connections among component developing processes such as component identification, component modeling, detailed design, code generation, deployment, and testing. And it is restrictive for users to construct various scales of components on component platform architecture. In this paper, we provide an implementation and a design of a supporting tool for constructing platform-independent software components, which covers all development lifecycles of components. In the phase of component modeling, platform independent, conceptual components are identified from domain model information in the view of system partitioning. Detailed design and implementation of a component are performed on the J2EE platform architecture. And the changes on the design model and source codes are consistently managed by using round-trip techniques.

In this paper, we developed the Distributed Programming Developing Tool(DPDT) which can make distributed application program efficiency based on the distributed object group framework supporting group management and dynamic binding for object resources requested from clients on distributed systems. The distributed object group framework we constructed provides not only the group register/withdraw, the access right and the name/property services for server objects from a point of view of group management services, but also dynamic binding, replicated object supporting, load balance, and federation among the object groups from a point of view of the supporting services of distributed application, When developing distributed application, by using our tool, server programming developer implements objects in each server system, next registers the properties to need for service provision to the object group. Client programming developer can also develop client program easily by obtaining the access right for the object or the object group and using the properties of objects with the access right permitted to the client. For providing above application developing environment in this paper. we described the definition of object group, the architecture of the distributed object group framework which our tool supports, and its functionalities, then specified the 3 GUI environments of DPDT implemented for providing efficient interfaces between the distributed object group and distributed applications. Finally, by using the DPDT, we showed the group register/withdraw and the access right grant procedure of objects which are server programs, the developing process of client program, and the executing results of the distributed application developed.

Due to increased software development cost, interest about the method and automated tool for reusing legacy system have been running high. Therefore, In this study, it proves the definition, concept and also background of legacy system by showing real market and technology trend. Automation tool is designed and developed to handle the concrete development methodology, procedure and reference. Also, we implemented the process that analyze the legacy system and extract, refine, store and reuse the candidate components by using LM(Legacy to Modern System) supporting tool presented in this paper. If LM supporting tool is applied to legacy system migration, we can expect cutting costs, shortening the developing period and succeeding the intellectual property by software re-engineering.

In order to prevent the production defects the optimum design of product, jig and fixture putting in the field is very significant manufacturing method. Drilling Jig is the device according to industrial demand for multi manufacturing products on the growing at alarming rate. In the field of design and making for machine tool working, welding, assembling with jig and fixture for mass production is a specific division. They require analysis of many kinds of important factors, theory and practice of machine tool operating process and jig & fixture structure, machining condition for tool making, tool materials, heat treatment of jig & fixture components, know-how and so on. In this study we designed and constructed a drilling jig of mass production and performed tryout under the Auto CAD, Auto Lisp database, that we made by database, and window environment. Especially this study is reveals with the analysis of part drawing, jig planning, jig design etc, and then the result of drill jig's making try out.

Recently, the development of high speed and high precision NC-lathe for piston head machining is needed for the complexity and diversity of the piston head shape used in automobile reciprocating engine. THe piston head has many complex shapes in the aspect of fuel economy, such as ovality, profile, double ovality and recess. Among them, for the maching of the over shape of 0.1~1mm the cutting tool should move periodically symchronized with the rotation of piston workpiece. The cutting tool feeed system must have high positioning accuracy for the precise machining, high speed for the fast maching and high dynamic stiffness for the cutting force. The linear brushless DC motor is used for satisfying these coditions. The ballbush guide and supporting guide using turcite is used for the guidance of the feed drive system. Linear encoder, digital servo ampllifer and controller are used for driving the motor. THis paper presents the design and simulation of the new tool feed system for noncircular machining.

This study provides a thorough methodology for IT Investment evaluation. A software tool to support the evaluation process was introduced along with a case study. The software supports the methodology that consists of 7 phases : Target analysis, ldentifying IT measures, Measuring IT impact, Assessing business value, Analyzing the decree of realization, Cost-benefit analysis, and Reporting. The case study showed that the software (CAFA) was a very useful tool supporting both decision-making and post-implementation reviews of IT investment.

XML이 표준화 제정될 당시 XML문서의 구조를 정의하기 위해 DTD를 사용하였다 DTD는 XML의 전신인 SGML에서부터 사용되어 왔으며 여러 훌륭한 기능을 지원하고있다. 그러나 DTD는 그 고유의 형식으로 이루어져있어 XML 개발자는 XML구문분석기 이외에 DTD 구문분석기를 별도로 개발하여야하고, DTD는 지원하는 데이터 형식에 제한이 있으며, 데이터 값의 범위 등을 설정할 수 없어 XML 문서의 유효성 검사에 제한이 많다. 이러한 문제를 해결하기 위하여 W3C에서는 XMLSchema를 제정하였다. DTD의 구문을 XML Schema로 모델링하였고, XML 문서에서 XML스키마를 적용하기 위한 도구와 DTD의 XMLSchema변환을 효과적으로 생성할 수 있는 GUI기반 XMLSchema Tool을 설계, 구현하였다.

Since the traditional designing approach of forming processes is based on trial and error it consumes much time and needs cost to design successful processes. Today for higher marketability of products a manufacturing system is required that can reduce production time and enhance product properties greatly. In order to implement the system a computerized design-supporting tool is indispensable for the design and supply of optimized production process for high product quality in short time In this study a design supporting system is developed and implemented to ballstud die. Using the developed system the designer can rapidly produce layouts of dies for each process sequences with consistency.
