본 연구에서는 실험 실습 가상교육 또는 원격 교육 콘텐츠가 학습 효과를 향상할 수 있는 효과적인 교육 수단으로 인정되고 있으나 원격에서 실험 실습을 하기위한 환경구성의 어려움을 극복을 위한 방안으로 웹 기반의 하드웨어 원격제어 기술을 이용하여, 임베디드 시스템 활용 교육을 위한 가상교육 시스템을 구현 하였다. 본 가상교육 시스템의 구성은 서버 시스템과 학습 시스템으로 되어 있다. 서버 시스템은 컴파일 서버, 원격 실습 서버, 웹 서버, Telnet 서버, 웹 카메라 서버 등으로 구성한다. 학습 시스템은 이론 강의, 가상 실습, 원격 실습의 세 부분으로 구성한다. 본 연구에서 구현한 시스템은 원격지에서의 프로세서 실습 환경을 제공하기 위해 웹에서 동작하는 Telnet 클라이언트를 제작하여 임베디드 하드웨어를 제어한다. 또한 이론학습 과정을 별도로 구성하고, 원격제어가 불가능한 개발환경 구축 과정은 가상 실습으로 학습하게 하였다. 이러한 점을 활용하여 임베디드 시스템의 효율적인 학습이 가능하다.

서로 다른 지역에서 서로 다른 과정의 실습 중심의 정보보호 단기 교육을 진행하기 위하여 SaaS 기반 가상훈련 시스템을 사용하였다. 본 논문에서는 SaaS 기반 가상훈련 시스템을 이용한 정보보호 실습 교육의 장단점을 정리한다. 강사 및 수강생들은 교육 과정 중 데스크톱 가상화를 사용하여 실습 환경을 구축하는 시간을 절약할 수 있었다. 또한, 원격 실습 지원, 진행 상황 확인도 가능하였다. 관리자는 강사 및 장소와 무관하게 균등한 실습 교육을 제공할 수 있다는 점이 가장 큰 장점이었다. 향후에는 서버 가상화와 데스크톱 가상화가 결합된 하이브리드 형태의 실습 환경 개발을 고려할 필요가 있다.

The purpose of this study is to compare the differences in transfer motivation and learning self-efficacy before and after applying virtual simulation for nursing in psychiatric nursing practice, and to provide them as basic data for effective psychiatric practical education. This study was conducted from October to December 2020. The subjects were 41 people who were enrolled in the third year of a located in U city, and who had received psychiatric nursing practice education using virtual simulation for nursing. Data were analyzed by paired t-test and pearson's correlation coefficient. After practice compared to before psychiatric nursing practice with virtual simulation nursing applied, transfer motivation was significantly increased and learner self-efficacy increased, but it was not statistically significant. Therefore, It was confirmed that psychiatric nursing practice education using virtual simulation for nursing is partly an effective practice strategy.

Laboratory works for embedded system courses are usually performed with hardware based experimental kits that equipped with an embedded board and software development tools. Hardware-based kits have demerits such as high initial setup cost, burdensome maintenance, inadaptability to industry evolution, and restricted educational outcomes. This paper proposes using virtual experimental environments to overcome the demerits of hardware-based kits and describes the design and implementation of a simulation-based virtual experimental kit. With ARM's ARMulator, we developed the kit by adding hardware IPs and user interface modules for peripherals. The developed kit is verified with an experimental program that uses all the augmented software modules. We also ported MicroC/OS-II on the virtual experimental kit for real-time OS experiments.

Purpose: This study aims to understand the online practice experience of nursing students through virtual simulation in order to prepare basic data for online practice program development. Methods: This study is a descriptive study that applied a qualitative thematic analysis method to explore the online practice experiences of nursing students. It was targeted to 16 students in the department of nursing at a university. Results: As a result, 5 themes such as 'Feeling ambivalent about the online practice', 'Doubts about the effectiveness of online practice', 'Running into the limits of online practice', 'Feeling like a virtual simulation as an alternative', and 'Approaching true nursing' Conclusion: Virtual simulation is considered a very effective online practice program. However, since the lack of various scenarios and cases is pointed out as a limitation, it is necessary to develop and apply more diverse and systematic practice programs in future research.

This study examined the reality of military counseling education applied by the Army and studied the effects of military counseling training using virtual reality. First, we explored the cases of virtual reality application related to counseling, reviewed the virtual reality technology that can be benchmarked in the Army military counseling education, and examined the applicable technology. We classified the education method and the curriculum for the students and tested the difference using the analysis of variance, which is a statistical analysis method, through the satisfaction measurement of the current education. In addition, after having students experience virtual reality contents, the effects of practical training applied with virtual reality technology were derived and the difference in actual training was compared and analyzed through T-test. Then, the reliability of the study was improved by analyzing the effects of practical training using virtual reality by using the Analytic Hierarchy Process for the expert group who can consider the overall situation. Based on the results of the analysis, the development plan of military counseling training combined with virtual reality technology and the supplements of current military counseling education were presented as policy implications.

Cloud computing is already well known paradigm that a support computing resource flexible and scalable to users as the want in distributed computing environment. Actually, cloud computing can be implemented and provided by virtualization technology. Also, various products are released or under development. In this paper, we built the teaching practice system using cloud computing and evaluated practical environment which constructed over a virtual machine. Virtualization-based cloud computing provides optimized computing resources, as well as easy to manage practical resource and result. Therefore, we can save the time for configuration of practice environment. In the view of faculty, they can easily handle the practice result. Also, those practice condition reuse comfortably and apply to various configuration simply. And then we can increase capabilities and availabilities of limited resources. Additionally, we measure the performance requirements for educational applications through evaluation of virtual-based teaching practical system in advance.

In order to overcome practical limitations in installing, managing and operating MRI machines with expensive equipment, this study developed and utilized virtual reality (VR) experience education by combining virtual reality (VR) with magnetic resonance imaging devices. The Students who experienced virtual reality-based educational systems were surveyed to identify possible side effects during the experience and self-directed learning ability and academic self-efficacy surveys were conducted to analyze the impact of virtual reality-based practice on learning. In the analysis of the self-directed learning ability survey there was no difference in the average between the student group who experienced education and the student group who did not but there was a significant difference in the average for each group. Virtual Reality-based practical education is expected to provide an efficient practice system by providing new learning methods and opportunities for education that can be repeated anytime, anywhere regardless of time and space.

The purpose of this study is to identify the differences in self-efficacy, clinical performance ability, and critical thinking disposition after applying education integrated educational virtual reality simulation to training and outside school clinical practice to nursing college students and to provide them as basic data for effective practical education. This study was conducted from June 8 to July 3, 2020, and enrolled in the 3rd year of university in G city, and 30 subjects who did not receive virtual reality simulation training or outside school clinical training at all. Data were analyzed by Paired t-test. As a result of the study, the result of pretest and posttest to each group showed statistically significant improvements in self-efficacy, clinical performance ability, and critical thinking disposition. As a results of the study, education integrating virtual reality simulation training and clinical practice for nursing students to improves clinical performance ability, improves critical thinking, and self-efficacy, so it is thought that various virtual reality simulation training must be suitable for clinical situations before practice is necessary.
