A dynamic simulation program for pantograph-catenary system is developed based on a mode superposition method to predict current collection performance. Formulations for the dynamic simulation are presented in this paper. The number of modes which should be considered for a KTX catenary system is reviewed through frequency response analyses. The responses for GPU pantograph - KTX catenary system are simulated with various train speeds. The our simulation results are in reasonably good agreements with RTRI simulation program, SNCF simulation program, and BR simulation program.

Purpose: This study was designed to develop and evaluate the a web-based simulation program on patient rights education using integrated decision making model into values clarification for nurse students. Methods: The program was designed based on the Aless & Trollip model and Ford, Trygstad-Durland & Nelms's decision model. Focus groups interviews, surveys on learning needs for patient rights, and specialist interviews were used to develop for simulation scenarios and decision making modules. The simulation program was evaluated between May, 2011 and April, 2012 by 30 student nurses using an application of the web-based program evaluation tools by Chung. Results: Simulation content was composed of two scenarios on patient rights: the rights of patients with HIV and the rights of psychiatric patients. It was composed of two decision making modules which were established for value clarifications, behavioral objective formations, problems identifications, option generations, alternatives analysis, and decision evaluations. The simulation program was composed of screens for teacher and learner. The program was positively evaluated with a mean score of $3.14{\pm}0.33$. Conclusion: These study results make an important contribution to the application of educational simulation programs for nurse students' behavior and their decision making ability in protecting the patient rights.

Simulation has been recognized as one of major application areas of world wide web. Over the last several years, most research has been focused on the development of web-based simulation languages mostly using JAVA and validation of simulation modeling on web with the newly developed languages. In this paper, we develop a tentative web-based simulator for a simple unit-load automated warehouse system, named Web-SAW. In constructing Web-SAW, we program a user interface program, a simulation logic program, and an animation program with JAVA while utilizing the class library functions and embodiment environment of existing web-based simulation languages. Web-SAW simulates the automated warehouse system with the user input about system operation, displays the animation on a static background representing the system, and generates the various textual outputs after simulation.

본 연구는 간호대학생을 대상으로 시뮬레이션 교육이 자기주도 학습능력, 메타인지, 임상수행능력에 미치는 효과를 파악하기 위해 실시되었다. 시뮬레이션 교육은 청주시 소재 대학교 간호학과 4학년 88명을 대상으로 팀별 사전토의, 팀 시뮬레이션, 디브리핑으로 구성되어 12주간 운영되었다. 사전 자료 수집은 2014년 10월 8일에, 사후 자료 수집은 12주간 시뮬레이션 교육이 종료된 후 2014년 12월 8일에 수행되었다. 연구결과, 시뮬레이션 교육 후 자기주도 학습능력(t=4.270, p<.001), 메타인지(t=4.435, p<.001)는 교육 전보다 통계적으로 유의하게 상승하였고, 임상수행능력은 교육 전보다 상승하긴 하였으나 통계적으로 유의하진 않았다. 그러므로, 간호대학생의 자기주도 학습능력, 메타인지, 임상수행능력 향상을 위해 보다 체계적인 시뮬레이션 교육과정의 개발 및 운영이 필요할 것으로 사료된다.

기존의 헬리콥터 모델링은 주로 많은 가정들을 통한 수식 전개에 의존해 왔기 때문에 모델링이 어렵고, 특정 구간에서만 활용 가능하며, 모델링 구성이 바뀌면 많은 수정이 거쳐야 한다는 단점들이 제기되어 왔다. 본 연구에서는 다물체 동역학 기법을 적용한 헬리콥터 시뮬레이션 프로그램을 개발하여 AH-1 헬리콥터에 대한 모델링을 수행하였고, 또한 시뮬레이션 결과를 비행 시험 데이터 및 상용 헬리콥터 시뮬레이션 분석 도구인 FLIGHTLAB과 비교하여 그 가능성을 확인해 보았다.

Smoke is one of the most critical factor when escaping from the fire since it reduces visibility and interrupts finding emergency exit lights. Therefore, it is recommended that an evacuation simulation program should incorporate the smoke factor. In addition, it is suggested that the program should include not only the unilateral damage by the smoke but also the detour evacuation by risk communication. In this study, MAS (Multi Agent System)-based simulation program which incorporates the reduced walking speed by smoke and adopts the dispersion evacuation logic during escaping from the fire. To make comparison, a commercial evacuation program, Pathfinder was used. It was found that the simulation results of MAS (Multi Agent System)-based program is better than Pathfinder in terms of safe evacuation. It means that evacuation simulation need a additional evaluation categories that include not only quick evacuation time but also safe evacuee number.

Purpose: This study was conducted to develop a simulation-based postpartum care education program for women with postpartum hemorrhage and to verify the effects of the program on postpartum care. Methods: This program was developed according to the ADDIE model of instructional system design, which consists of analysis, design, development, implementation, and evaluation phases. This quasi-experimental study used a non-equivalent control group pre- and post-test design, and data were collected from April 23 to May 4, 2015. To verify the effects of the program, 33 nursing students in the experimental group participated in a simulation program, whereas 31 students in the control group were given a case study. Results: The experimental group had statistically significantly higher scores for clinical performance (t=-4.80, p<.001), clinical judgment (t=-4.14, p<.001), and learning satisfaction (t=-10.45, p<.001) than the control group. Conclusion: The results of this study indicate that the simulation-based postpartum care education program for women with postpartum hemorrhage was effective for developing students' competency, implying that a similar program should be integrated into the clinical training component of the maternal nursing curriculum.

Purpose: Clinical training for nursing students is limited to rudimentary skills to avoid potential risks. Simulation-Based Training (SBT) can overcome the shortcomings of clinical training. We evaluated the educational effect of SBT for obstetrical nursing students using high-fidelity simulation courses. Methods: We developed a simulation program for obstetrical nursing students to practice nursing skills that are necessary to provide quality care. The program consisted of four sessions. 1st: An orientation and a preliminary test. 2nd: Learning core skills required in obstetrical nursing. 3rd: Testing each student with scenario. 4th: Providing a debriefing session. At the beginning of the program, students were surveyed about their self-confidence in obstetrical nursing care, and at the end of the program, they were surveyed about the adequacy of SBT as well as self-confidence. Results: Students' self-confidence showed a significant difference before and after simulation. Mean adequacy of SBT was $7.15{\pm}1.35$ (out of 10). Most students became more interested in Women's Health Nursing after SBT. Conclusion: The results from evaluating the effects of simulation-based obstetrical nursing training show that SBT provides invaluable clinical experience for obstetrical nursing students by overcoming the lack of actual clinical involvement in clinical training programs.
