다국어 초록 (Multilingual Abstract)

Purpose: The purpose of this study is to develop and apply a virtual reality training program to improve the performance of archery and support psychological technology training. Methods: To explore changes in visual exploration strategies during the training interval and neurophysiological changes after program application, researcher analyzed using Functional near-infrared spectroscopy, virtual reality devices, eye movement tracking equipment, and simulation images. The experiment conducted a total of 8 simulation training sessions twice a week for 4 weeks, and it took about 20 to 30 minutes for each session. Repeated measurement ANOVA was conducted to find out the change in the HbO level of the prefrontal cortex and the difference in group, pre and post-test for Dorsolateral Profrontal Cortex (DLPFC). Post-analysis was conducted using Bonferonni corrections for the main effect and interaction in which significant differences were found. In virtual reality training (Section 1: Before the buzzer of the shot, Section 2: First shot, Section 3: Second shot, Section 4: Third shot, Section 5: Aiming section), descriptive statistics and t-test were conducted for pre-post comparison according to the group for data on the measurement of gaze behavior patterns for each section. Results: As a result of verifying the hemodynamic change of DLPFC, the oxygen saturation of the right DLPFC in the experimental group was found to maintain the level of the pre-test in the post-test, but the control group decreased in the post-test and oxygen saturation of the left DLPFC decreased in post-test than in pre-test in both groups. As a result of analyzing the gaze fixing time to confirm the effect of virtual reality (VR) simulation training, there was a difference in the pre and post-measurement of the experimental group and the control group(2, 3, 4, 5 sections), and only in 4 sections in the number of gaze movements. Conclusion: As a result of these studies, it is judged that stabilization and consistency of gaze processing of archers can be expected through repeated VR simulation training.
