The Paper Using the meta-analysis research method, first through literature retrieval to obtain 23 relevant empirical studies in China, and then using Review Manager for quantitative analysis, it is found that VR technology has a positive impact on students' overall learning effect and VR technology has a significant positive impact on all dimensions of learning effect (theoretical performance, operational performance, learning motivation, learning interest, learning attitude). There is no significant difference between the dimensions. Significant differences were found for moderating variables such as Discipline types, Teaching Length, and Teaching Method. No significant differences were found for the Academic segments and VR technology types.

This study is about the development of a device that reduces bacterial diffusion and odor by improving the water quality of the toilet using ozone water. In public toilets used by an unspecified number of people, various pollutants and pathogens are present in the toilet. These substances that are harmful to the human are dispersed in the form of aerosols into the air through toilet flushing. Aerosols containing various contaminants may flow into the user's respiratory tract or spread to the skin and cover, serving as a medium for various diseases. In order to prevent this spread, it is essential to continuously maintain cleanliness inside the toilet. Therefore, in this study, ozone water that can improve the water quality of the toilet was used as a way to keep the toilet environment clean. A device that is mounted in a toilet tank and continuously generates ozone water to improve pollutants inside the toilet was designed and developed.

This study aims to enhance the cultivation of SWㆍAI basic competencies of middle school students by forming and distributing SWㆍAI education programs for middle school students who form the basis of their lives. In addition, by planning SWㆍAI education programs in connection with the regular curriculum, it is intended to serve as a cornerstone for the public education of SWㆍAI education that will be implemented from 2025. To this end, the concept of SW and AI in middle school was first defined and a plan to link software/artificial intelligence learning factors to the regular curriculum was proposed, and based on this, SWㆍAI education programs for middle school students were prepared. Based on literature research, the understanding of artificial intelligence technology, the value of data, and the use of artificial intelligence technology in real life were set as SWㆍAI education contents, and educational programs were organized by linking them with the current middle school curriculum. All SWㆍAI education was organized in the form of practice rather than theory so that classes could be conducted centered on participants, and the purpose of the course was to cultivate the ability to use artificial intelligence technology in real life based on understanding artificial intelligence technology.
