Abstract: There are provided a scenario similarity retrieval-based automatic scenario generation system and method. According to an embodiment, a scenario retrieval-based automatic scenario generation method includes: retrieving scenarios similar to a query scenario from a scenario DB for an autonomous driving test; filtering only scenarios that meet a selection condition from the retrieved scenarios; and converting components of the filtered scenarios to suit a target condition. Accordingly, a desired scenario may be automatically generated by retrieving a scenario similar to a targeted scenario, converting the retrieved scenario, and concretizing the scenario.

Abstract: An air conditioner for a vehicle with an improved structure so that hot air is not directly discharged to a defrost vent in a floor mode or a mix mode, includes an air conditioning case in which an air flow path is formed, and a cooling heat exchanger and a heating heat exchanger provided sequentially on the air flow path of the air conditioning case in an airflow direction, wherein a defrost vent, a face vent, and a floor vent are formed on the air conditioning case, wherein the defrost vent includes a first defogging flow path allowing air passing through the heating heat exchanger to be discharged directly, and a second defogging flow path allowing air passing through the cooling heat exchanger or the heating heat exchanger to be mixed and discharged therethrough.

Abstract: A pre-coating filter device includes: a filtration tank comprising a raw water inlet through which raw water flows on one side, and a drain port at the bottom; a top cover coupled to the upper part of the filtration tank and comprising a coupling hole through the middle part; a purified water discharge pipe coupled to the coupling hole of the top cover; a purified water storage space unit coupled to the lower part of the top cover and located within the filtration tank, and comprising a communication pipe connected to the central part; a filter coupling plate body coupled to the lower part of the purified water storage space unit and comprising a plurality of coupling holes through; and a pre-coating filter coupled to the coupling hole of the filter coupling plate body.

Abstract: The present invention is to provide a vending machine for engraved medals and a method of automatically engraving medals wherein an engraver is contained in the vending machine, and if a coin or a note is inserted into the vending machine and a starting button is pushed according to messages displayed on a monitor, a desired type of medal is selected and loaded on a bed of the engraver to be engraved according to a selected image, and the engraved medal is taken out outside the vending machine.
