Abstract: The present invention relates to a vaccine composition for preventing or treating coronavirus disease (COVID-19) comprising a recombinant adenovirus as an active ingredient. The present invention enhances immune responses against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is a severe pandemic that has resulted in millions of deaths worldwide, through the recombinant adenovirus, and thus may be useful as a prophylactic vaccine composition that provides fundamental and efficient protection against SARS-CoV-2.

Abstract: A system to provide circadian-friendly lighting for nighttime hospital care comprising a lighting module and a transmitter tag that interface wirelessly wherein the lighting module comprises red-shifted light spectra, which is proven to be less disruptive to melatonin production than current blue-shifted hospital lighting; wherein the light output of the devices is modulated by the proximity of a tag to the device, with light intensity increasing with closer proximity between these two components and decreasing with increased distance, thereby providing hands-free lighting to caregivers in the specific locations where they need light to perform care tasks.

Abstract: A bulletproof equipment for protecting personnel against a projectile fired from a gun or the like. The equipment includes a inflatable bulletproof air bag for protecting a targeted individual from fire of a weapon; an air tank for ejecting compressed gas or air into the air bag; a high speed fan for feeding air into the air bag when the air bag is punctured; a controller for controlling the associated components; and a power supply for applying electric current.
