Abstract: There is provided a cooperative driving control method based on a vehicle security status. The cooperative driving method according to an embodiment includes: identifying a security status of a cooperative driving target vehicle; determining a cooperative driving strategy according to the identified security status; and controlling driving according to the determined cooperative driving strategy. Accordingly, cooperative driving may be performed or excluded based on a security status of a target vehicle, so that an accident may be prevented from being caused by cooperative driving with a problematic vehicle, and safety of a driver and an occupant may be guaranteed.

LidPSeX2f??[Chemical Formula 2] Here, d satisfies an equation 4?d?7, e satisfies an equation 3?e?7, f satisfies an equation 0?f?2, X2 includes Cl or Br, and an ionic radius of X1 is greater than an ionic radius of X2.

Abstract: Provided is a system for preventing snow from piling or freezing into slippery ice on a road in the winter season. The system comprises a case, an antifreeze fluid supply tank installed in an upper portion of the case, an electric heater installed in a lower portion of the case to heat an antifreeze fluid supplied from the antifreeze fluid supply tank, a circulation pump connected between the antifreeze fluid supply tank and the electric heater to supply the antifreeze fluid to the electric heater, an antifreeze fluid discharge pipe connected to one side of the electric heater to discharge the heated antifreeze fluid outside the electric heater therethrough, a synthetic resin hose buried under a road and connected to the antifreeze fluid discharge pipe at one end thereof, and an antifreeze fluid return pipe connected between the other end of the hose and a middle portion of the antifreeze fluid supply tank.

Abstract: The present invention relates to a headset having a transmitter which is freely rotatable in 3D with respect to a handset housing of a headset. In a headset which includes a built-in handset housing which is electrically connected with a micro speaker and a printed circuit board, a connection line connected with an external terminal from the handset housing, a cushion ring coupled through the handset housing, a headband which is coupled to an upper cover and is putted on a user's head, and a microphone and transmitter connected with the upper cover for thereby transferring a certain sound wave, there is provided a transmitter connection structure of a headset which includes a socket formed in an outer side surface of the upper cover, the microphone formed in a lower portion of the socket in the handset housing, and a ball which is detachably engaged to the socket and is formed in an outer side surface of the transmitter.
