Abstract: According to the present disclosure, a query information processing method of a database performed on a computing device includes: identifying query information requested from a client; acquiring initial search result data from a fully homomorphic encrypted database in response to the query information; performing a finite extension field-based grouping operation in response to the initial search result data; and providing the grouping-operated search result data to the client.

Abstract: According to the present disclosure, a query information processing method of a database performed on a computing device includes: pre-building a plaintext index corresponding to a fully homomorphic encrypted structured database; generating an encryption index by homomorphically encrypting the plaintext index; identifying query information requested from a client; indexing the encryption index in response to the query information; acquiring search result data through a homomorphic operation corresponding to a result value indexed by the encryption index; and providing the search result data to the client.

Abstract: An artificial turf structure includes a protective layer, a buffer layer disposed on a lower surface of the protective layer and having a three-dimensional structure comprising a front surface layer, an intermediate layer and a rear surface layer, a bubble layer disposed on a lower surface of the buffer layer, a pile unit tufted to the protective layer, the buffer layer and the bubble layer, and a backing layer disposed on a lower surface of the bubble layer and preventing the pile unit from leaving.

Abstract: Disclosed is a USB adapter for a vehicle that can effectively dissipate heat generated during power supply and data transmission. The USB adapter includes a casing installed at a center fascia or a console box of the vehicle, wherein one surface of the casing is open; a printed circuit board received inside the casing, wherein a USB port is mounted at one end of the printed circuit board and a receptacle is mounted at the other end of the printed circuit board; and a heat dissipation member configured to transfer heat generated during power supply and data transmission to the casing, such that the casing dissipates the heat out of the USB adapter.

Abstract: Provided herein are a probe capable of simultaneously detecting a virus and treating virus-infected cells, a composition for detecting a virus, which comprises the probe, a composition for treating a virus, which comprises the probe, and a method of detecting a virus or treating a viral infection by using the same. According to the present disclosure, it is possible to simultaneously perform diagnosis by virus detection and treatment of virus-infected cells, and in particular, diagnosis and treatment may be simultaneously performed on various types of viruses by varying the type of molecular beacon, and thus may be usefully applied to virus diagnosis and treatment fields, which require rapid diagnosis and treatment, and the spread of viral infections may be effectively prevented. In addition, the probe of the present disclosure has excellent stability and excellent detection sensitivity, and thus enables the detection of even a very low amount of a target at the pmole level.

Abstract: An apparatus includes a first camera module providing a first image of an object with a first field of view, a second camera module providing a second image of the object with a second field of view different from the first field of view, a first depth map generator that generates a first depth map of the first image based on the first image and the second image, and a second depth map generator that generates a second depth map of the second image based on the first image, the second image, and the first depth map.

Abstract: Provided is casting equipment and a casting method using same. A casting method includes: preparing a tundish; injecting molten steel to the tundish; installing a vacuum forming member on an upper portion of the tundish to form vacuum in at least a partial area of an upper portion of a melting surface of molten steel accommodated in the tundish; forming a rotational flow by blowing a gas into the molten steel; and forming vacuum in at least a partial area of the upper portion of the melting surface of the molten steel. More particularly, the present disclosure may effectively remove inclusions in the molten steel and restrict reoxidation of the molten steel.

Abstract: A safety system for bicycle riding is capable of preventing collision of a bicycle by generating vibrations to alert a rider to a dangerous situation when a front object is detected within a collision risk distance and is capable of reducing accidents by emitting a light beam to alert a driver of a rear object to a dangerous situation when the rear object is closely approaching.
