This paper presents a well-designed templating system for CMS web Publication using XML/XSL technology. The primary motivation is the need of Web CMS to separate content from layout and logic. Our system provides GUI XSLT editor (x-editor) to create and modify XSLT stylesheet documents easily. These documents are used to add "layout" and "look and feel" information to XML document which contains content and functionality. The modified XML document is processed by XML-template engine to produce dynamic or static web sites.

With its recent popularity, Web is now considered as a huge repository of information. Most documents on the web have been created using HTML(Hyper Text Markup Language). Even though HTML is simple and easy to learn, it has several features that are obstacles to the efficient information retrieval. XML(eXtensible Markup Language) can provide a solution to such problems and in fact, has already been used in many applications, XML is a standard markup language for exchanging data on the web. It can describe a document structure freely by defining its DTD, which enables efficient integration and retrieval of data on the web. In this paper, we propose a versatile and efficient XML document manager. Its features include (i) form-based XML editor that enables easy creation of new XML documents, (ii) automatic document converter that can transform HTML documents with similar structure into XML documents automatically, and (iii) GUI-based DTD editor.

Hand shape is one of important elements in Korean Sign Language (KSL), which is a communication method for the deaf. To express sign motion in a virtual reality environment based on OpenGL, we need an editor which can insert and modify sign motion data. However, it is very difficult that people, who lack knowledge of sign 1anguage, exactly edit and express hand shape using the existing editors. We also need a program to efficiently construct and store the hand shape data because the number of data is very large in a sign word dictionary. In this paper we developed a KSL hand shape editor to easily construct and edit hand shape by a graphical user interface (GUI), and to store it in a database. Hand shape codes are used in a sign word editor to synthesize sign motion and decreases total amount of KSL data.

Researches on particle physics have benefited our everyday life in many aspects. They have tested the safety of the objects we use everyday, conducted experiments to examine harmful environments to man, and treated diseases. Despite the usefulness of particle physics in a range of fields, however, it's difficult to conduct researches and experiments directly. But the advancements in the computer industry have allowed for experiments of particle physics in virtual simulations. One of the foremost simulation libraries for particle physics that have been researched actively these days, Geant4 has been put to diverse uses in particle physics. This study designed GUI so that physicists, who were not good at programming, could use a simulation library faster, more accurately, and more conveniently. It also developed the Geant4Editor, a simulation automation framework. The advantages of the Geant4Editor include automatic generations of essential classes in a simulation using Geant4 libraries and real-time reflection of user demands in a simulation. It also allows for efficient management of resources(user-created data) through the Data Manager.

This study is focused on developing a program which can edit different formats of power system data used by system operators PSS/E program, which has been widely used as a tool for power system analysis. Provides only a limited function of editing PSS/E input data. Considering that more and more power system analysers will be developed and applied for power system planning and operation in the near future, unified handling of multi-types of power system data format, such as conversion of one input data format into another, is indispensible. In this paper, a new power system data editor, functionally augmented from PSS/E editor, is introduced. The new editing program was developed in GUI environment for users to conveniently edit input data for EUROSTAG program without running several editors. Considerable savings in time and manpower are expected.

현재 GUI 인터페이스와 컴퓨터 기술의 발전으로 다양한 형태의 그래픽 모델링 도구들과 시각 프로그래밍 시스템들이 사용되고 있다. 이러한 시스템들을 개발하기 위해서는 사용자가 그래픽 요소들의 형태와 그래픽 요소들간의 연결 관계를 개발자가 직접 프로그램을 이용해서 작성하여야 하기 때문에 많은 시간과 노력을 필요로 한다. 이러한 문제를 해결하기 위해서 본 논문에서는 그래픽 요소의 형태와 그래픽 요소들간의 연결성을 직접 조작 방식을 이용해서 기술할 수 있는 토큰 편집기인 TEdi(Token Editor)와 시각 프로그래밍의 기본적인 기능을 지원할 수 있는 AVE(Abstract Visual Editor)를 소개한다. TEdi는 그래픽 요소들을 정의하기 위해서 사용되며, 토큰 단위의 각 그래픽 요소는 다른 그래픽 요소와 연결되기 위해서 연결자를 사용한다. 연결자는 그래픽 편집기에서 연결될 수 있는 그래픽 요소를 제한함으로써 시각 프로그래밍 혹은 모델링에서 구문 오류를 줄여줄 수 있다. 본 논문에서 제공하는 시스템을 사용하는 경우에 사용자는 보다 쉽게 그래픽 요소와 시각 프로그래밍 혹은 모델링 도구를 작성할 수 있을 것이다.

A power plant simulation tool ('PowerSim') has been developed with 10 years experience from the development of a plant simulator for efficient modeling of a power plant. PowerSim is the first developed tool in Korea for plant simulation with various plant component models, instructor station function and the Graphic Model Builder (GMB). PowerSim is composed of a graphic editor using general purpose design software, a netlist converter, component models, the scheduler, Instructor Station and an executive. The graphic editor generates a netlist that shows the connection status of the various plant components from the Simdiagram, which is drawn by Icon Drag method supported by GUI environment of the PowerSim. Netlist Converter normalizes the connection status of the components. Scheduler makes scheduling for the execution of the device models according to the netlist. Therefore, the user makes Simdiagram based on the plant Pipe and Instrument Drawing (P&ID) and inputs the plant data for automatic simulating execution. This paper introduces Graphic Model Builder (GMB), instructor station, executive and the detailed introduction of thermal-hydraulic modeling. This paper will also introduce basic ideas on how the simulation Diagram, based on netlist generated from general purpose design software, is made and how the system is organized. The developed tool has been verified through the simulation of a real power plant.

생산일정계획 수립 시스템을 통하여 수립된 생산계획을 현장에서 실천하고자 할 때, 일반적으로 계획수립 후 얼마 지나지 않아 계획수립시 고려할 수 없었던 기계고장 또는 자재조달 지연, 작업 지체, 주문 취소 등과 같은 요인으로 생산일정을 계획대로 실천할 수 없는 경우가 발생한다. 이런 상황에서는 기존의 생산계획을 계속 실행할 수 없으므로 손쉽게 대처할 수 있는 방안이 필요하다. 본 연구에서는 일정계획편집기를 이러한 문제점을 해결할 수 있는 대안으로 제시한다. 일정계획편집기를 GUI, 객체지향적 설계를 통해 구현하므로서 이상상황과 일정변동에 효과적으로 대처할 수 있다. GUI환경을 통해, 수립된 생산일정과 이상상황, 작업진척, 수행도 등을 화면에 Gantt 도표로 표시해 주어 현장 파악을 용이하게 하고 작업추가, 삭제, 작업시간 변경, 대체공정으로의 이동 등의 편집을 mouse와 icon을 이용, 편리하게 수행할 수 있다. 편집작업시 자동으로 생산일정의 타당성을 만족시켜 줄 수 있는 지능화를 위한 기초 단계로서 객체지향설계를 이용한 규칙기반 일정계획 편집기를 설계한다.
