The purpose of this study was to analyze the effectiveness of integrated simulations conducted by virtual simulation and in situ simulation among nursing college students during COVID-19. This study was conducted from July 7 to 9, 2020 and the participants included 126 fourth-year nursing college students. Integrated simulation consisted of virtual simulation, teledebriefing, pre-briefing, in situ simulation, and debriefing. The results showed that after the use of various simulation modules and the training of integrated simulations incorporating virtual and in situ simulation training, critical thinking (t=5.20, p=<0.001), clinical judgment (t=6.71, p=<0.001), and simulation effectiveness (t=3.53, p=0.001). These findings could help establish the direction for more diverse forms of simulation-based education and it should be conducted in future nursing simulation during this COVID-19 pandemic era.

Purpose: The purpose of this study was to explore the meaning of nursing students' experiences in virtual simulation practice. Methods: The participants were six nursing students who have experience in a virtual simulation. Data were collected from August to September 2019 through a focus group interview. Giorgi's phenomenological method was used for analysis. Results: The study results revealed 3 constituents and 6 sub-constituents that are essential for nursing student's experiences in a virtual simulation. The three constituents were: "Chaos in the virtual reality", "The process of adjusting to chaos", and "Becoming an independent nurse in a safe virtual reality". Conclusion: Based on the results of this study, the following suggestions are made. Results suggest the development of virtual simulations in Korean, the use of simulations as a group activity first, and the use of simulation between lecture and practice or in the regular curriculum. The results of the study can be used as primary data for providing virtual simulation in nursing education.

Purpose: The purpose of this study is to identify the educational needs of virtual reality simulations that can be applied to novice nurses during the waiting period before starting work in a hospital. Methods: A convergent mixed methods was used. The survey data were collected from 230 novice nurses, and a focus group interview was conducted with 6 new nurses. The data were collected from November 2022 to January 2023. Descriptive statistics, a frequency analysis, independent t-test, and an Importance-Performance Analysis were performed using SPSS 24.0. Results: Appropriate topics for virtual reality simulation education were indicated to be medications and intravenous injections, which are high priority topics in quantitative and qualitative research. The novice nurses wanted group activity training three to four times a week for two weeks before beginning work in a hospital. They also wanted an immersive virtual reality system based on a real hospital environment. Conclusion: Based on the above results, this study provides basic data for the development of a virtual reality simulation education that can improve the adaptation of novice nurses to clinical practice. A strategy was suggested to utilize the waiting time before beginning work in a hospital as educational time.

산업안전을 위한 가상훈련시스템들 중 마중형 햅틱 제시 시스템에서는 가상 및 실제 물체 사이의 자연스러운 상호 작용을 위해 시각-촉각 일치가 필요하며 이를 위해 캘리브레이션이 수행된다. 본 논문에서는 어느 정도의 시각-촉각 일치를 구현한 몰입형 VR 햅틱 시스템의 사용자 평가를 수행하였다. 평가의 목표는 실제 및 가상환경에서 수행하는 일정한 과업들에 대해 두 환경에 대한 사용자 성능 (반응시간 및 거리 정확도)이 크게 다르지 않다는 것을 보이는 것이다. 사용자 평가 결과는 반응 시간에서 통계적으로 유의한 차이가 보이지만 절대 차이는 1초 미만이며 거리 정확도는 가상 환경과 실제 환경 간에 차이가 없는 것을 보여준다. 따라서 개발된 햅틱가상훈련시스템은 값비싼 실제 환경을 대신하여 저렴하게 산업안전 훈련을 할 수 있다고 사료된다.

Background: Most pain management techniques for challenging procedures are still performed under the guidance of the C-arm fluoroscope although it is sometimes difficult for even experienced clinicians to understand the modified three-dimensional anatomy as a two-dimensional X-ray image. To overcome these difficulties, the development of a virtual simulator may be helpful. Therefore, in this study, the authors developed a virtual simulator and presented its clinical application cases. Methods: We developed a computer program to simulate the actual environment of the procedure. Computed tomography (CT) Digital Imaging and Communications in Medicine (DICOM) data were used for the simulations. Virtual needle placement was simulated at the most appropriate position for a successful block. Using a virtual C-arm, the authors searched for the position of the C-arm at which the needle was visualized as a point. The positional relationships between the anatomy of the patient and the needle were identified. Results: For the simulations, the CT DICOM data of patients who visited the outpatient clinic was used. When the patients revisited the clinic, images similar to the simulated images were obtained by manipulating the C-arm. Transforaminal epidural injection, which was difficult to perform due to severe spinal deformity, and the challenging procedures of the superior hypogastric plexus block and Gasserian ganglion block, were successfully performed with the help of the simulation. Conclusions: We created a pre-procedural virtual simulation and demonstrated its successful application in patients who are expected to undergo challenging procedures.

Purpose: The purpose of this study was to examine the effects of a virtual reality simulation and a blended simulation on nursing care for children with asthma through an evaluation of critical thinking, problem-solving processes, and clinical performance in both education groups before and after the educational intervention. Methods: The participants were 48 nursing students. The experimental group (n=22) received a blended simulation, combining a virtual reality simulation and a high-fidelity simulation, while the control group (n=26) received only a virtual reality simulation. Data were collected from February 25 to 28, 2019 and analyzed using SPSS version 25 for Windows. Results: The pretest and posttest results of each group showed statistically significant improvements in critical thinking, problem-solving processes, and clinical performance. In a comparison of the results of the two education groups, the only statistically significant difference was found for critical thinking. Conclusion: Simulation-based education in child nursing has continued to involve high-fidelity simulations that are currently run in many programs. However, incorporating a new type of blended simulation, combining a virtual reality simulation and a high-fidelity simulation, into the nursing curriculum may contribute to the further development of nursing education.

We introduce a piece of special-purpose equipment for responding to disasters that has a dual-arm manipulator consisting of six-axis multi joints, and a master-slave operating system controlled by a wearable joystick for intuitive and convenient operation. However, due to the complexity and diversity of a disaster environment, training and suitable training means are needed to improve the interaction between the driver and equipment. Therefore, in this paper, a system that can improve the operator's immersion in the training simulation is proposes, this system is implemented in a virtual environment. The implemented system consists of a cabin installed with the master-slave operation system, a motion platform, visual and sound systems, as well as a real-time simulation device. This whole system was completed by applying various techniques such as a statistical mapping method, inverse kinematics, and a real-time physical model. Then, the implemented system was evaluated from a point of view of the appropriateness of the mapping method, inverse kinematics, the feasibility for real-time simulations of the physical environment through some task mode.
