This study aimed to develop virtual reality (VR)-based content on surgical aseptic techniques for nursing students and evaluate its effectiveness. Methods: The content was developed following the system development life cycle, involving analysis, design, implementation, and evaluation. Experts and fourth-year nursing students validated the content for its validity and usability of the content. The study was conducted from December 2022 to April 2023. Results: The VR content was developed using Keller's ARCS motivational design model (attention, relevance, confidence, and satisfaction) as the fundamental strategy. Upon applying the VR content developed in this study, the research participants confirmed the values of the following sub-factors: confidence (3.86 out of 5), relevance (3.74 out of 5), attention (3.68 out of 5), and satisfaction (3.65 out of 5). Conclusion: VR-based surgical content on aseptic techniques demonstrates potential benefits for nursing students. Therefore, through systematic development and utilizing of diverse nursing skill content, we can enhance the core competencies of nursing students, providing them with high-quality practical education.

The purpose of this study was to determine the conditions necessary for the total eradication of mite pests in indoor environments. The study involved the construction of a sterilization experimental setup. For this setup, various sterilization techniques, such as UV-C, ozone, ultrasound, and heat were applied, based on previous research. The experimental procedure consisted of placing mite pests in a chamber and subjecting them to different sterilization techniques. Observations were conducted immediately after the experiment and repeated five days later to assess the extent of eradication. The results showed that UVC, ozone, and ultrasound methods were not successful in completely eradicating the mite pests. In contrast, heat sterilization demonstrated effectiveness depending on the specific temperature and exposure time. To achieve the eradication of mite pests in indoor environments, it is necessary to maintain conditions of short-term high-temperature sterilization above 65°C or sustain temperatures above 50°C for a minimum duration of 90 minutes.
