본 논문에서는 HEVC 기술로 부호화된 비디오 비트스트림(HEVC 비트스트림)을 분석하고, 그 결과를 보여주는 방법에 대해서 제안한다.[1] HEVC 기술은 Coding Unit(CU), Prediction Unit(PU), Transform Unit(TU)을 기반으로 부호화가 이루어지므로 부호화 정보를 효과적으로 사용자에게 보여주기 위해서는 CU, PU, TU 를 기반으로 GUI(Graphic User Interface)가 디자인되어야 한다. 제안된 HEVC 비트스트림 분석기에서는 이러한 부호화 구조를 반영하여 사용자 친화적으로 HEVC 비트스트림의 부호화 정보를 편리하게 확인할 수 있도록 하였다.

본 논문은 안전해석 등에 사용되는 RETRAN-3D 등 최적해석 코드를 기반으로 하면서도 복잡한 하드웨어 없이 간편한 GUI (Graphic User Interface)를 이용하여 광범위한 발전소 과도상태를 해석하기 위한 다양한 기능을 통해 시뮬레이션 조작을 쉽게 할 수 있는 웨스팅하우스형 950MW급 최적 원전운전분석기 (Nuclear Plant Analyzer)를 다루고자 한다. WH형 950MW 원전 운전최적분석기는 기존의 단순한 Point Kinetics 모델이 아닌 정교한 3D 실시간 노심모델과 RETRAN 코드를 기반으로 하는 실시간 NSSS 열수력 모델 (ARTS)이 통합된 모델을 갖추고 있으며, 해당형식발전소 (WH 3 Loop PWR Plant : 고리 3,4호기, 영광1,2호기 원전)의 여러 가지 과도사고를 실시간으로 정상, 비정상, 비상운전 등으로 모의할 수 있도록 개발되었다. 모의결과 주요 과도 상태의 결과가 해석한 결과와 잘 일치하였으며, 해당형식 발전소 과도 분석이나 규제요원 훈련에 이용될 계획이다.

This paper describes the simulation environment that verifies whether a new microporcessor described with HDL is compatible with an existing microprocessor. The compatibility verification is done by showing that the new microprocessor executes the OS(Operating System) program used in the existing microprocessor without any modification of its binary code. The proposed verification environment consists of a virtual system and a graphic user interface (GUI) module. Each module is independently designed based on serve-client model and three exists a communication part for information interchange between the two modules. This paper describes the method of constructing the verification environment and presents the compatibility verification environment of the x86 microprocessor as the simulation result.

MMI 시스템은 제철 공정에서 발생되는 다양한 데이터를 조업자에게 쉽고 빠르게 전달하기 위해, real time operating system에서 동작하는 제철공정의 주된 제어 프로세스와 인터페이스 한다. 따라서 MMI 시스템은 제철 공정의 주된 제어 프로세스와 ethernet network을 통해 공유 데이터들을 통신하도록 개발되고, MMI 시스템은 M/S window operating system과 DDE(Dynamic Data Exchange) 라이브러리 환경을 기반으로 개발된다. 수 개의 MMI client PC와 1 개의 MMI server로 구성되는 MMI 시스템은 MMI client들 사이의 공유 데이터가 동기화될 수 있도록 최적 packet 양을 도출하고, 신뢰성 높은 데이터 전송을 위한 특별한 데이터 핸들링 방법을 사용한다. MMI 시스템은 GUI(Graphic User Interface)를 사용하여 조업자에게 친숙한 window 화면을 제공하므로, MMI 시스템의 화면 수정, 첨가 및 삭제가 비용 부담없이 용이하게 진행되므로, 기존 제철 공정에서 사용하던 OCP(Operating Control Panel)들이 MMI 시스템으로 대체되고 있다.

The design program of fitting and thrust block including various shapes and sizes was developed for the GMR project (Great Man-made River Project in Lybia). It can automatically recalculated the minimum size of fitting required for the structural performance and can also determine the proper size of fitting for the safe and economic design by users. It was found that the results of this program was accurate and efficient when it was compared to other references. This program is also developed with GUI (Graphic User Interface) technology for the convenience of users.

The roll Pass design is one of the most important processes to design the whole equipment of the rods and bars rolling system. In this study, the roll pass design program named TollRo(Rolling Factory Organizer) was developed. conventional methods to design roll pass were analyzed and a new algorithm to design the dimension of the intermediate groove was introduced. Object oriented programming technology was implemented in this design program. It comprises GUI(Graphic User Interface), function of automatic pass design, function of modifying pass schedule and database of material properties. The developed program can be used to design roll pass with consistency for the rods and bars rolling system. The man-hours for the whole design can be drastically reduced. The design parameters of rolling system can be extracted quickly by this program.

A decision support system for determining reservoir capacity, named as KORESIDSS (KOwaco's REservoir SIzing Decision Support System), was developed. The system is composed of three subsystems; a database/information subsystem, a model subsystem, and an output subsystem. This system is operated using MS-Windows with a GUI (Graphic User Interface) system developed using Visual Basic 5.0. As a continuous runoff model, the DAWAST model (DAily WAtershed STreamflow model) developed by Noh(1991) was and its analysis module was developed. This system was applied to a newly-planned dam, the Cheongyan Dam, Which will be located in Cheongyang-Gun, Chungcheongnam-Do and it was proved to be applicable in determining reservoir storage.

In university of Korea, the computerization of facility management is lower level than other management areas such as educational matters, administration, library, computing center, teaching assistance, and teaching methodology. So we need urgently the blueprint for an information-oriented and integrated facility management system. In this research, It is presented and implemented an FMS(Facility Management System) for efficient management of the ground and underground facilities on a campus. This studies is computerized the drawings, protocols, and ledgers. It is used a GIS(Geographic Information System) to get the geographical information of facilities. The data more efficiently could be search and update on this system. The decision making process understanding the present facility condition, and analyzing the condition of location could be performed easily by the GUI(Graphic User Interface) of the system.

In this paper, the illuminator is designed to recognize the shape and the existence of holes of radiation fin in the point that the light reflection characteristics are different according to the roughness of the material. The threshold value, the positions of holes and the black pixel nembers in the positon are obtained under the illuminator, in accordance with the reference image, by applying binary conversion and hole segmentation algorithm, as they are suggested in this paper, The existence and shape of hole are recognized by calculating the distance and feature value in the test image, which is obtained from the parameters of reference image. It is programmed to apply to GUI(Graphic User the Interface) in windows. More than 98% of recognition rate is shown, as it is applied to three different sizes of the radiation fin.
