The technologies’ originality, innovation, and merit procured through patent applications for the aforementioned areas of implementation (configuration and operation). - Construction materials and air handling systems with anti-viral photocatalysts are widely used in ordinary residential and public facilities; stimulation of construction and photocatalyst industries expected. - Increased movement of the global population is causing a sharp rise in the number of people suffering from new and mutated infectious diseases. The MERS epidemic in 2015 highlighted the need to implement permanent quarantine and anti-epidemic systems to prevent the spread of infectious diseases. Improving systems to control infectious diseases will help solve a variety of social problems. ㅇ Expected effects - Early detection of high-risk infectious diseases from overseas and preventing these diseases from entering the country through immigration facilities such as airports and ports and permanent suppression of secondary infection at major public facilities such as hospitals; ensuring public safety and reducing socioeconomic losses due to infectious diseases. - Resolves social unrest and alleviates public concern over infectious diseases, which cause large economic losses through reduced consumption, poor exports, and poor competitiveness for export products. - Allows for a quick, initial response at airports and ports against infectious diseases from overseas, ensuring public safety and preventing direct costs of treatment, as well as indirect economic costs.
