KEPCO Research Center is carrying out a simulator(full scope replica type) development project for two nuclear power plants(Kori-2, Younggwang-3,4) and one fossil power plant(Poryong-3,4). In this project, we aim not only the installation of high performance simulators at the power plant sites but also the realization of self reliance of power plant simulation technology in Korea. In the course of preparing procurement specification for the 3 simulators, the present status of power plant simulation technology has been surveyed and is presented in this paper. The fidelity of simulation and the automation of simulation model production has been greatly improved due to the ever increasing computing power of today's workstations. The need and importance of the application of high fidelity simulators to the operator training is refocused since the accident at TMI Nuclear Power Plant, U.S.A.

Colleges have been forced to take non-face-to-face classes this year due to the COVID-19, and the situation is expected to continue unless the development of treatments and vaccines is carried out as soon as possible. In the situation where non-face-to-face classes are required under compulsion, two methodologies have been suggested as most representative alternatives to face-to-face classes: online real-time classes and on-demand contents classes. The purpose of this study is to compare the perceived convenience, self-fidelity, and preference of students between online real-time and on-demand contents classes by gender, school year grade, mostly using class media, and number of courses taken. Comparative results between online real-time and on-demand contents classes were statistically analyzed by surveying students at a university.

본 연구는 마취과 임상실습을 마친 의전원 4학년 학생들을 대상으로 충실도를 달리한 과정기술 객관구조화 진료시험에서 보여지는 자기평가와 학습동기의 변화 유무를 비교해 보고자 시행되었다. 학생들을 무작위로 두 군으로 나누어 HF군에서는 고충실도의, LF군에서는 저충실도의 과정기술 객관구조화진료시험을 시행하였다. 사례는 기관삽관과 정맥관삽관의 두 주제로 임상술기교육을 맡은 책임교수가 개발한 후 다른 두 교수가 검토, 수정하였다. 두 주제에 대해 고충실도 사례는 실제 수술실에서 in-situ 시뮬레이션으로, 저충실도 사례는 일반 교실에서 단순과업모형을 이용하여 충실도만 달리하여 시행하였다. 학생들은 수행 전 후로 5점 척도로 구성된 설문조사에 응하였고, 자료의 분석은 Man-Whiteney test와 Paired T-test를 이용하였다. 연구 결과, 의전원 4학년 학생들의 술기 수행능력에 대한 자기평가는 저충실도 사례보다 고충실도 사례에서 평가 전에 보여준 자신감보다 낮게 평가되었고, 고충실도 사례 후에 연습의 필요성을 더 느꼈다. 고충실도 사례의 도입은 학생들의 술기연습에 대한 동기 부여에 도움이 될 것으로 여겨지지만 경제적인 효율도 고려해야 할 것이다.

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.

Purpose: This study aimed to compare the effects of simulation integrated with problem based learning (S-PBL) according to the sequences of problem-based learning (PBL) and high fidelity simulation training (HFS) on knowledge, clinical performance, clinical judgment, self-confidence, and satisfaction in fourth-grade nursing students. Methods: In this randomized crossover design study, four S-PBLs on medical-surgical nursing were applied alternatively to two randomly-assigned groups of 26 senior nursing students for 8 weeks. The collected data were analyzed using an independent t-test. Results: The method of administering PBL prior to HFS led to significantly higher scores on knowledge (t=2.28, p=.025) as compared to the method of administering HFS prior to PBL. However, the latter method led to significantly higher scores on clinical performance (t=-6.49, p<.001) and clinical judgment (t=-4.71, p<.001) as compared to the method of administering PBL prior to HFS. There were no differences in the effect of the two methods on self-confidence (t=1.53, p=.128) and satisfaction (t=1.28, p=.202). Conclusion: The integration sequences of S-PBL was associated with different learning outcomes. Therefore, when implementing S-PBL, it is necessary to consider the educational goal to executes an appropriate sequence of integration.

Over the past decade, driven by advances in educational theory and pressures for efficiency in the clinical environment, there has been a shift in surgical education and training towards enhanced simulation training. Microsurgery is a technical skill with a steep competency learning curve on which the clinical outcome greatly depends. This paper investigates the evidence for educational and training interventions of traditional microsurgical skills courses in order to establish the best evidence practice in education and training and curriculum design. A systematic review of MEDLINE, EMBASE, and PubMed databases was performed to identify randomized control trials looking at educational and training interventions that objectively improved microsurgical skill acquisition, and these were critically appraised using the BestBETs group methodology. The databases search yielded 1,148, 1,460, and 2,277 citations respectively. These were then further limited to randomized controlled trials from which abstract reviews reduced the number to 5 relevant randomised controlled clinical trials. The best evidence supported a laboratory based low fidelity model microsurgical skills curriculum. There was strong evidence that technical skills acquired on low fidelity models transfers to improved performance on higher fidelity human cadaver models and that self directed practice leads to improved technical performance. Although there is significant paucity in the literature to support current microsurgical education and training practices, simulated training on low fidelity models in microsurgery is an effective intervention that leads to acquisition of transferable skills and improved technical performance. Further research to identify educational interventions associated with accelerated skill acquisition is required.

In this paper, attendance in distance learning courses of a cyber university has been surveyed in an effort to verify the effectiveness of distance learning. Based on survey data from 4,749 distance learning participants, major attending place, major reasons for attending online class, fidelity to online classes, attending time per week, perceived educational effectiveness, perceived and relative seriousness of problems, and other variables have been evaluated. The results indicate that perceptional seriousness of the investigated problems is not statistically important. The findings indicate that, among operational problems, self willingness and cheating are the most remarkable. In contrast, the relative seriousness of traditionally recognized problems such as H/W availability and network speed among environmental problems is least remarkable. An analysis of demographic differences such as sex, employment, and school year in terms of seriousness of problems is also performed. The results reveal the existence of statistically significant differences according to sex, employment, and school year with regard to almost all elements of environment, actual current conditions, and seriousness of problems, with the exception of some elements such as attending place and perceived fidelity.

Purpose: The purpose of this study was to evaluate the effects of mechanical ventilation simulation on the clinical judgment and self-confidence of nursing students. Methods: This study was a quasi-experimental study. From one university, 118 undergraduate nursing students participated in this study. Sixty students were in the intervention group, and fifty-eight students were in the control group. A simulation scenario utilizing a high-fidelity human simulator focusing on nursing care for patients with a mechanical ventilator was developed for this study. Data were collected with a self-report survey method before the intervention, right after intervention, and two weeks later. Results: Students in the intervention group showed significantly higher increases in clinical judgment and self-confidence than those in the control group at the immediate posttest. Moreover, 2 weeks later, the increase in clinical judgment and self-confidence from the pretest among the intervention group was significantly larger than those in the control group. Conclusion: Utilizing simulation education focusing on patients with a mechanical ventilator may contribute to training more competent nurses in the area of critical care nursing. It may also serve to provide a better critical care environment for the safety and health of patients.
