최근 오픈 소스 소프트웨어를 활용하여 리눅스 기반의 모바일 플랫폼을 구성하려는 추세를 보이고 있다. 특히 최종 사용자(end-user)와의 상호 작용(interaction)을 담당하는 모바일 UI 프레임워크로 GTK+를 많이 사용한다. 본 논문에서는 GTK+의 구조에 대해서 살펴보고, 데스크톱 기반의 GTK+를 모바일 UI 프레임워크에서 사용하기 위하여 고려해야 하는 주요 이슈(issue) 들을 살펴본다.

This paper describes the GUI implementation of an intelligent embedded system which can be used for a personal information platform and an industrial mobile application system. It shows the architecture and the necessary structure and components of X Window graphic system. The embedded system used in this paper has low power and high performance processor, and has a large memory size with a nand-flash memory device. We configured the linux kernel with a TIT-LCD and touch screen device for the operation of X Window system. And we used GTK+2 for running application softwares on the platform embedded system. The GUI library of GTK+2 is useful for providing the same graphics programming environment with host Linux PC. We have developed in this paper the X Window system and the GUI environment for GTK+2 in a new embedded system, and verified the full operation of X Window system and application softwares using GTK+2. The embedded system with large memory size can be used in X Window application softwares for providing a personal information service with a mobile embedded system.

The Study on the technique of applying the method USB redirection on Linux-based SPICE-GTK VDI solution for in (Virtual Desktop Infrastructure) VDI solution for Android-based USB redirection in this paper. VDI solutions are developed according to the development of many of the latest Android-based devices, but a VDI solution that supports USB redirection is limited. Also does not support USB redirection of Android to use the SPICE VDI solution. Therefore, the text presents the techniques applied to the Android-based VDI solutions applied to analyze the way USB redirection of SPICE-GTK VDI solution based on Linux. G PRO smartphone devices to install and use Linux-based VDI server to a test of the method applied in this paper, and the USB redirection applied VDI clients using a USB storage device, USB redirection is done playing files results you can check

Primary purpose of the system developed in this study is 3-D seismic data processing system for underground investigation and this system is developed in PC based on Linux for lower-cost system. Basic data processing modules are originated from SU (Seismic Unix) which is widely used in 2-D seismic data processing and auxilious modules are developed for 3-D data processing The system which is constructed by using these data processing modules Is designed to GUI (Graphic User Interface) in order that one can easily control and for this purpose, GTK (Gimp Tool KiT) conventionally adapted in producing Linux application.

이 논문은 철근 가공 산업 현장에서 스프레드쉬트에 의해 수작업으로 행하던 절단 작업의 계획 수립을 자동화된 시스템에 의해 최적의 절단 계획을 생성하도록 하는 소프트웨어의 개발을 다룬다. 이를 위하여, 먼저 시스템의 데이터 표현과 최적 문제 풀이를 위한 자동 계획 알고리듬의 설계가 요구된다. 이것은 다중 규격의 1차원 자재 절단 문제를 푸는 것으로, 동적계획법에 근거하여 자재 절단 문제를 재구성하고, 유한 범위의 조합 열에서도 근사 최적의 해를 찾을 수 있는 탐색 기법을 사용한 자재 절단 계획 알고리듬을 사용하였다. 그리고, 자동화된 철근 가공 산업용 소프트웨어는 작업 환경에 맞게 사용이 편리한 그래픽 화면과 사용자 인터페이스가 요구되는데, 공개 소프트웨어를 활용한 GUI 라이브러리 툴킷인 GTK+를 활용하여 이를 구현하였다.

The value of a system is highly dependent upon its reliability, Reliability means not merely correctness but means fault tolerance of the system. This paper emphasizes software fault tolerance in design stage especially in case of computer controlled system. The general method of fault tolerance design especially including dual computer system and its advantage and disadvantage was introduced. Finally for example of fault tolerance design we would like to present our GTK-500 EPABX.

VoIP that conveys voice in internet is getting into the spotlight as means to alternate existing PSTN in corporation as well as users. Current VoIP is furnishing voice efficiently, but it needs to support various services for VoIP acceleration. IETF is developing CPL standard which is call processing language for supporting various services. User has to store script to specific server for the use of CPL, therefore it is required client to support CPL. This paper describes about design and implementation of SP-based CPL client for various services. The CPL client was implemented using LINUX 2.4.x, C, and GTK1.2.

PDA(Personal Digital Assistant)는 GUI(Graphical User Interface) 환경이 필수적이다. 최근 기존의 개인정보 관리기능 외에 휴대단말기를 내장한 인터넷 기능, 멀티미디어 기능, 게임 등이 가능한 고성능의 PDA가 일반화됨에 따라, 기존의 단일 task 환경 대신 뛰어난 GUI와 멀티미디어 환경을 지원하는 내장형 운영 체제가 사용될 전망이다. 본 논문에서는 Linux의 GTK+/GDK(GNU Image Manipulation Program Toolkit) 툴킷을 이용하여 Framebuffer를 직접적으로 사용할 수 있게 하고, 불필요한 내부 함수를 제거함으로써 X-윈도우시스템으로 인한 오버헤드 및 저장공진을 줄일 수 있는 내장형 운영체제를 설계 및 구현한다.

In this paper, we deal an implementation of the software that produces sub-optimal solution of cutting-ironbar planning problem using dynamic programming. Generally, it is required to design an optimization algorithm to accept the practical requirements of cutting ironbar manufacturing. But, this problem is a multiple-sized 1-dimensional cutting stock problem and Linear Programming approaches to get the optimal solution is difficult to be applied due to the problem of explosive computation and memory limitation. In order to overcome this problem, we reform the problem for applying Dynamic Programming and propose a cutting-ironbar planning algorithm searching the sub-optimal solution in the space of fixed amount of combinated columns by using heuristics. Then, we design a graphic user interfaces and screen displays to be operated conveniently in the industry workplace and implement the software using open-source GUI library toolkit, GTK+.
