이 논문은 고리 $\#$1 원자력 발전소를 기준 발전소로 하여 개발되고 있는운전원 교육용 가상 시뮬레이터 의 일부로서, 제어봉 제어계통 모델링에 대한 내용을 제시하는 것이 주된 목적이다. 제어봉 제어 계통의 목적은 원자로 출력을 변화시키기 위하여 제어봉 집합체(RCCA)를 동작시켜 단기적인 반응도(Short Term Reactivity)를 조절하기 위한 것이다. 실제 발전소와 똑같은 제어봉 제어가 가능하면, 실제로 운전원이 가상 시뮬레이터를 통해서 모든 상황과 사고들을 대처하는 능력을 가질 수 있도록 설계되었다 본 논문에서는 고리 $\#$1 원자력 발전소 운전원 교육용 가상 시뮬레이터를 구현하기 위해 현재까지 설계된 제어봉 제어계통의 기능, 구성, 제어봉 제어에 대한 전반적인 내용을 제시하고자 한다.

A correctly designed bridge offers improved operational safety in terms of increased vigilance, flexibility of operation, precision of control and operator＇s situational awareness. According1y to design human centered bridge, the consideration shall be given to the man-machine interface, location and interrelation of workstation, configuration of console, windows. field of vision and bridge working environment. The state-of-the-art suits for one-man operation by integration of conning information and central information presentation. Further, it is desirable to enable two man ship operation for emergency operations, training purposes and redundancy. In this point of view, this thesis would like to design a conceptual bridge.

This paper presents a new method for representing complex power system phenomena using 3-D computer graphics animation. The proposed method was tested on both the generator dynamics phenomena and subsynchronous resonance phenomena. It is anticipated that the proposed method would be helpful for the operator training as well as power system education.

A target signal simulation method for passive sonar systems is introduced. The method uses multirate signal processing techniques to simulate moving target signals in the multi-path sound propagation environment by introducing Lloyd's mirror and Doppler effect. Time and frequency variation of target signal due to the target maneuvering is also considered to provide realistic ship signatures in the LOFAR gram so that the simulated target is used for sonar operator training. Synthesized target characteristics is analyzed and compared with real target signal in terms of interference pattern and frequency variation in the LOFAR gram.

This paper presents a new method for representing SSR(Subsynchronous Resonanace) Phenomena using 3-D computer graphics animation. A virtual power system simulation environment was made for simulation and visualization of SSR phenomena. It is anticipated that the proposed method would be helpful for the operator training as well as power system education.

A helicopter is used in a variety of situations because of its usability. Its operation, needs human skill. The authors are working on automatization of human skill. Helicopter operation is one of such fields of practicing human skill. This is why the present paper deals with helicopter (model helicopter) operation. Full operation of a helicopter needs more complicated system in both aspects of software and hardware, and also requires more training for operation. From the purpose here that helicopter operation is for checking the applicability of the authors' idea for automatization based on experience, attitude regulation in hovering is the target. In the present paper, a human operator's operation is recorded as a time series of operation actions, and the record is reorganized as the correspondence between the helicopter's attitude and the proper operation action required in that particular situation.

A low cost PC based simulator for excavator manipulation has been developed using virtual reality technology. The simulator consists of two joystick input devices, server and client PCs, an excavator kinematics module, and a graphic rendering program Open Inventor. In order to use two joysticks in the PC window environment multi-thread programing with network protocol TCP/IP has been used. To provide realistic view to the operator, CAD program Pro/Engineer and 3D modeller have been employed to create 3D part geometry of tile manipulator and virtual environmental geometries. Those geometries also have been transformed and imported to the Open Inventor. The Simulator developed is to be improved for more realistic excavator operational training.

When a large scale system and its machinery have a trouble, an inexperienced personnel has a difficulty to find out a countermeasure and to understand the situation quickly. In this paper, a Online Guide Application using 3D Virtual Reality is proposed, and it will be used for operator to work out a countermeasure quickly and to see a trouble situation widely. This application shows possibility of minimizing effects of an incident by presenting effective troubleshooting process. moreover, this is expected to be applied to training program.

The spacecraft simulator is used for command validation, operational check of the Satellite Operation Subsystem (SOS), spacecraft anomaly analysis support, satellite operator training etc. In this paper, S/W design features and modeling characteristics of the KOMPSAT Spacecraft Simulator Subsystem (SIM) are described. Validation procedures and simulation results are also provided. The SIM provides extensive simulation capabilities by including models for most of the spacecraft subsystems. The software structure of the SIM was designed and implemented so as to support operations not only in real-time but also in non real-time by utilizing the Hewlett Packard (HP) UNIX functions. The SIM incorporates as many user-friendly Man Machine Interface (MMI) windows as possible so that all the SIM normal operations can be executed through the MMI windows.
