Abstract: A vehicle seat reinforcement device includes a leg portion mounted on a floor panel, a seat cushion frame slidably mounted on the leg portion, and a load reinforcing structure connected between the leg portion and the seat cushion frame, wherein when a seat belt anchorage load is transferred to the seat cushion frame, the seat cushion frame is locked to the leg portion by the load reinforcing structure.

Abstract: The present invention provides a system and method for high-precision fire simulation-based virtual fire training interaction that features a fire suppression support virtual fire training interaction that combines a scientific fire simulation (FDS) result expression technology used for fire situation analysis and a real-time interaction technology processing dynamic changes in order to have more realistic training in virtual fire training such as fire suppression.

Abstract: The present invention provides a composition for improving sexual function comprising at least one compound as an active ingredient selected from the group consisting of arginine derivatives or pharmaceutically acceptable salts thereof. The composition of the present invention does not act as a substrate for arginase, but increases the generation of nitric oxide in endothelial cells along with enhancing the expression of nitric oxide synthase and induces the increase of the content of cGMP related to an erection depending on the concentration, thus remarkably exhibiting the effects of improving sexual function.
