The main objective of this study is to show how to measure the education effectiveness of simulator system in the army. We investigate the education effectiveness through the measuring model that consists of three dimensions such as understanding, experience, and learning. The results of empirical analysis demonstrate that the education effectiveness depends on three dimensions. The result also suggests that the higher the degree of each dimension is, the higher the education effectiveness. However, there is no education effectiveness difference between the traditional training and the simulator training because of the elementary level of simulator function.

This paper presents a graphical windows-based program for the education and training for novel network reduction. The object of developed simulator is to provide users with a simple and useable tool for gaining an intuitive feel for power system analysis. The developed simulator consists of the main module (MMI,GUI), the location marginal price module (LMP), the clustering module and network reduction module. Each module has a separate graphical and interactive interfacing window. The developed simulator needs with the PSS/E input data format, generator cost function, location information. Line admittances of reduced network was determined by using the power flow method(Newton-Raphson). So line flow of reduced network is almost same to original power system. Results of reduced network are compared on the window in the tabular format. Therefore, the developed simulator can be utilized as a useful tool for effective education and training for power system analysis.

In this paper a Hybrid Real Time HVDC Simulator fur both operator Training and Researching in the Cheju-Haenam HVDC System is proposed and its performance is studied by means of RTDS (Real Time Digital Simulator), EMTDC (Electro-Magnetic Transients system for DC), PSS/E (Power System Simulator for Engineering), and experienced scenarios. The objective of this paper is to represent the strategy in development for KEPCO's hybrid HVDC simulator for the Cheju-Haenam HVDC system. This simulator consists of two DC stations, DC cables, external digital/analog controllers, monitoring systems and control desk for education, and AC networks. Its suitability for operator's education is tested during startup/shutdown and normal state operations. Dynamic performances of it are also verified.

Simulator is being utilized usefully in industrial education. Especially, it is the best method to use for the higher value-added business or hazardous system to train. Also, it is needed to effect in forward-looking industrial education changing from theoretical education to hands-on training. Therefore, the development of equipment that can be used in both theory and experience class and its application to education help you to maximize the training effect on LPG transportation method when you work in the field. As a result of its applying to the education, the understanding of transportation system of educational equipment came out 4.86 points of 5 points, the utilization on site had 4.47 points/5 points, and the satisfaction has 0.5 points/4.48 points. The LPG transporting system(simulator) is considered effective when it is utilized in the education.

Many digital logic circuit simulators have been developed for the education on the experiments of digital logic circuits for college or high school students. But the existing simulators have some constraints on the number of inputs of gate, on the display of gate and wire states, and on the number of logic diagrams to be simulated. 1n this paper, we propose a simulator XSIM(eXpandable digital logic circuit SIMulator) which mitigates the constraints and allows multiple diagrams for large scale logics. It is expected that the multiple diagrams on large logics are helpful for team-teaching in school.

This paper summarizes an education and training system for the auto-reclosing of power transmission system using a real time digital simulator. The system is developed to understand the principle of reclosing and the sequence of automatic reclosing schemes, and practice the effects of reclosing actions to power system in real-time simulator. This study is concentrated into the following two parts. One is the development of real time education and training system of automatic reclosing schemes. For this, we use the RTDS(real time digital simulator) and the actual digital protective relay. The mathematical relay model of RTDS and the actual distance relay which is equipped automatic reclosing function are also used. The other is the user friendly interface between trainee and trainer. The various interface displays are used for user handing and result display. The conditions of automatic reclosing which is a number of reclosing, reclosing dead time, reset time, and so on, can be changed by the user interface panel. A number of scenario cases are reserved for the education and training. Through the test, we verified that the proposed system can be effectively used to accomplish the education and training of automatic reclosing.

There are many difficulties and inconveniences in the process of completing driving education for the disabled. Even in the content of driving education, various unpredictable unexpected situations occur during actual driving. Although education on emergency situations is being conducted in the current driving education course, education to cope with various unexpected situations is insufficient. Therefore, in this paper, we propose a Unity-based driving education simulator for the disabled. Create a simulator by composing scenarios for various unexpected situations using Unity. A simulation is conducted through the test subjects, and the coping score for the existing unexpected situation is evaluated according to the evaluation items. It was confirmed that the evaluation score of the ability to cope with unexpected situations of the proposed system was higher than that of the existing driving education simulator. If the proposed system is used, it can be expected to improve the ability to cope with unexpected situations and improve the quality of life through realistic driving experience.

Standard oral and maxillofacial three-dimensional model was developed with patients' medical data while virtual reality (VR) simulator was developed in conjunction with head mount display (HMD) and Haptic device. The objective of this study was to evaluate the preclinical use of a VR training simulator in tooth preparation practice. Eighty-nine dental students were trained how to operate the simulator. The participants were then given sufficient time on the simulator to practice dental preparation. The students experience and opinion was then taken in through filling of questionnaires. On average content received 1.8 points, anatomy had 2.5 points, 2.6 points for the applicability, and 2.0 for the usability. As for the detailed items scores, queries about the possible development of the simulator and the interest of the learning process through the simulator were the highest at 3.1 and 3.0 points, respectively. Question about the benefit of the HMD and the haptic device during the practice had 1.5 and 1.6 points, respectively. The average total score was 2.2 points. VR tooth preparation simulator in the field of clinical dental education has powerful potential in regard to realistic models, environments, vision, posture, and economical efficiency.
