It has not been revealed which is more effective: an education program using virtual reality technology or a simulation education program using Sim-man.

In this study, the participants are new doctors who graduated from medical school and started working as interns at hospitals. The participants were divided into two groups. One group received a training program using virtual reality technology, and the other group received simulation training using Sim-man. The investigators would like to compare the increase in confidence and satisfaction before and after training.

After the classes and surveys are completed for each group, the participants will be able to receive other educational methods if they wish.

- The educational program was designed for participants to experience an emergency setting where a patient's oxygen saturation falls. The scenario starts with the decrease in the patient's oxygen saturation and the patient's condition could be changed according to the intern's management. The scenario includes various situations in which oxygen saturation could decrease, and the patient's condition changes depending on the expected responses of participants.

The scenario has been revised and supplemented through expert meetings.

• Experience two types of cases: an easy case where the patient's condition improves just by connecting an oxygen line, and a difficult case where the patient's condition does not improve even after connecting an oxygen line.
• A training program is prepared before the interns start work. The participants are divided into two groups (test group and control group). The test group wears an HMD (head-mounted display) and experiences both easy and difficult cases.
• The control group participates in simulation training using Sim-man, and the scenarios are the same for the test group (easy cases and difficult cases).
• Training on coping skills is provided through debriefing after VR and simulation.
• After completing the assigned program, participants can take the program that was not assigned to them if they wish.
• Both the test and control groups will fill out questionnaires before and after training to see changes in confidence and coping skills before and after training.
