Abstract: Disclosed are a method and apparatus for controlling an inverter of an eco-friendly vehicle, which may generate noise outside of a frequency band audible to infants in a protection mode. The control method includes calculating a current noise frequency, determining whether the current noise frequency is higher than a target noise frequency, and changing a current inverter switching frequency based on the real-time motor rotation frequency to generate noise corresponding to the target noise frequency when the current noise frequency is lower than the target noise frequency. Accordingly, it may be possible to prevent noise generated when the eco-friendly vehicle is driven from affecting the sense of hearing of an infant in the vehicle, whose audible frequency band is higher than that of an adult, thereby preventing hearing loss of the infant.

Abstract: Disclosed is a composition for preventing, treating or ameliorating a viral infection disease, which is safe for human application since the safety of a reactive oxygen species production inhibitor and a reactive oxygen species scavenger has already been verified. The disclosure utilizes inversely the mechanism of viruses which induces oxidative damage of a host cell and then activates viral replication and infection. Although not having direct specificity to a specific virus like existing vaccines, the composition can effectively inhibit proliferation of all viruses including oxidative stress, regardless of virus type or mutations. It can be applied as a sub-universal infection inhibitor and therapeutic agent as a limited alternative to vaccines that must be newly developed each year due to emergence of new viruses or viral mutations, and is expected to be used as a preventive agent or auxiliary agent to prevent epidemics.
