In recent years many people are changing their mobile phones from feature phones to smart phones because huge number of useful smart phone applications are released onto the market everyday. Development of smart phone applications could be very helpful educational contents for technologically gifted children who has lots of curiosity and creativity. For this reason this paper deals with development of smart phone application UI(User Interface) layout education programs for the technologically gifted children. These education programs which can operating under Android-based smartphone, have been developed by using JAVA and Eclipse. Survey from the technologically gifted children education experts has been analyzed by Delphi method to figure out effectiveness of the developed education programs.

This paper describes an implementation of the document class editor based on ODA(Open Document Architecture). For processing, we divided document structure into generic logical structure and generic layout structure as ODA standard. Also this editor could edit document profile. Using the utility which was implemented to investigate the composed document by object. we confirmed the document. And we could verify the ODIF stream data of the document. We designed this editor based on DAP level 2 of international functional standard. This system was implemented in environment of the X window system and the Motif as graphical user interface. This document class editor will be used to create real document having specific document structure.

Due to the rapid growth of ship building industry and increment of ship construction in Korea, several hundred thousand of lifting lugs per year, have been installed at the lifting positions of ship block and removed after finishing their function, therefore, appropriate design system for strength check or optimal design of each lug structure has been required in order to increase the capability of efficient design. In this study, design system of D-type lifting lug structure which is most popular and useful in shipyards, was developed for the purpose of initial design of lug structure. Developed system layout and graphic user interface for this design system based on the C++ language were explained step by step. Using this design system, more efficient performance of lug structural design will be expected on the windows of personal computer.

Web development and Internet technology development bring many kinds of works to web. This is the main reason why XML, document standard is popular. XML in web can be used to express document template or standard. XML with java can be more powerful and general. For example, XML can be used to transmit data and to print data into the screen using Ajax in JSP(Java Server Page) and to make interfaces in android, which is useful to reduce development cycle. However, XML is not easy to learn for the novice. In this paper, we propose the easy and effective way to reduce the learning curve of XML and to make and use XML documents. For the purpose, we suggest template base XML document generation and we design and implement XML document generator based on Template. XML document generator of template-based provides user interface and layout of XML document. So, users can generate XML document easily and effectively.

Variable Reference Graph 는 C 언어로 작성된 프로그램으로부터 상호 절차적인 자료 흐름 분석 정보를 수평적 방향 그래프(directed graph)로 자동 생성해주는 역공학(reverse engineering) 도구들 중 하나이다. 본 논문에서는 판독성 있는 구조적 정보를 제공하기위한 그래픽 표현의 전략을 바탕으로 JAVA 로 구현된 그래픽 사용자 인터페이스(graphic user interface) 및 그래프 레이아웃 알고리즘(graph layout algorithm)을 기술한다. 이 알고리즘은 4 단계로 구성되어 있다: 정보 모형, 레벨 알고리즘, 순서 알고리즘, 위치 알고리즘. 각 단계별에서 수행되는 주요 알고리즘을 살펴 본다. 특히, 이 알고리즘들은 사이클(cycle) 및 비사이클(acyclic) 방향 그래프, 그리고 트리(tree)를 수평적 계층 구조를 생성하는데 사용될 수 있다. 본 논문에서 구현된 Variable Reference Graph 는 소프트웨어 재공학 도구를 개발하는 RESORT(RESearch on object-oriented SOftware Reengineering Technology) 과제에서 개발되었다.

Most recent mobile devices can store a massive amount of images. However, the typical user interface of mobile devices, such as a small-size 2D display and discrete-input buttons, make the browsing and manipulation of images cumbersome and time-consuming. As an alternative, we adopt motion-based interaction along with a 3D layout of images, expecting such an intuitive and natural interaction may facilitate the tasks. We designed and implemented a motion-based interaction scheme for image browsing using an ultra mobile PC, and evaluated and compared its usability to that of the traditional button-based interaction. The effects of data layouts (tiled and fisheye cylindrical layouts) were also investigated to see whether they can enhance the effectiveness of the motion based interaction.

Gaining information via the internet is becoming pivotal in today's society as the internet is becoming the center of knowledge and information. The goal of this study is to present the guideline of web interface design for the elderly who are alienated in gaining information from the Internet. If the internet were more user friendly to the elderly, they would be able to spend more time in doing what they enjoy and also in self development, with the information gained on the internet. This study investigated current portal sites to understand the present situation, surveyed and interviewed the elderly, and researched literatures on how the elderly perceive various stimulants and also researched documents for previous guidelines on interface design for them. This study investigated internet sites which the elderly use to gather information about products and which entice their purchasing desires. The conclusion is that the usability can be improved by eliminating visual dizzy elements in the pages, simplifying the layout and the menu designs which represent the information architecture.

In this paper to cope with the reduction of products life-cycle as the variety of products along with the various demands of consumers, a virtual simulator is developed to make the changeover of manufacturing line efficient to embody a virtual simulation similar to a real manufacturing line. The developed virtual simulator can design a layout of a factory and make the time scheduling. Every factory has one simulator so that one product can be manufactured in the factories to use them as virtual factories. We suggest a scheme that heightens the agility to the diversity of manufacturing models by making the information of manufacturing lines and products models to be shared. The developed unit simulator can construct a proper virtual manufacturing line along with the required process of products using several kinds of operator and work cell. A user with the simulator can utilize an interface that makes one to manage the separate task process for each manu(acturing module, change operator components and work cells, and easily teach tasks of each task module. The developed simulator was made for users convenience by Microsoft Visual C++ 6.0 that can develop a program supplying graphic user interface environment and by OpenGL of the Silicon Graphics as a graphic library to embody 3D graphic environment. Also, we show that the simulator can be used efficiently for the agile manufacturing by the communication among the factories being linked by TCP/IP and a hybrid database system made by a hierarchical model and a relational model being developed to standardize the data information.

Due to the distribution of digital camera, many work for photo management has been studied. However, most work use a sequential grid layout which arranges photos considering one criterion of digital photo. This interface makes users have lots of scrolling and concentrate ability when they manage their photos. In this paper, we propose a clustering method based on a temporal sequence considering their color similarity in detail. First we cluster photos using Cooper's event clustering method. Second, we makes more detailed clusters from each clustered photo set, which are clustered temporal clustering before, using maximal clique finding algorithm of interval graph. Finally, we arrange each detailed dusters on a user screen with their overlap keeping their temporal sequence. In order to evaluate our proposed system, we conducted on user studies based on a simple questionnaire.
