Abstract: A refrigerator for storing a beverage at an optimal temperature to stably supercool the beverage and maintain the beverage in a supercooled state, and that can rapidly produce a supercooled beverage while maintaining the supercooled state of the beverage. A supercooling apparatus of the refrigerator includes a storage to which chilled air is supplied from a chilled air supply unit, a supercooling compartment positioned in the storage and refrigerated by the chilled air to indirectly refrigerate an object therein, a hole formed at one side of the supercooling compartment to allow flow of the chilled air into and from the supercooling compartment, and a damper to open or close the hole. The object is directly or indirectly refrigerated in the supercooling compartment according to user's selection by opening or closing the damper.

Abstract: Disclosed herein is a method of coating nanoparticles with a metal oxide. The method includes substituting surfaces of hydrophobic nanoparticles with an organic substance having a hydrophilic group effective to render the nanoparticles hydrophilic; and injecting the hydrophilic nanoparticles and a precursor of the metal oxide into an organic solvent including an amphiphilic surfactant to coat the nanoparticles with a metal oxide.

Abstract: Disclosed are a barb-wired single crystalline silicon micro needle and a biopsy method and a medicine injecting method using the same. The micro needle comprises a main body part, at least one extension part formed on a side surface of the main body part, and a protrusion part protruded from both side surfaces of the extension part. A medicine storage is formed on a surface of the main body part. A fluid passage is formed in the extension part and the main body part. It is easy to pick the tissue sample with the protrusion part just by inserting and extracting the extension part of the micro needle into and from the tissue for a biopsy. Therefore, the biopsy procedures can be simplified. In addition, the medicine in the storage can be injected into the tissue via the fluid passage.

Abstract: Disclosed is a catheter used to pick a sample of a lesion cell tissue existing in the living body, and more particularly a catheter capable of freely coupling or separating a micro biopsy tool and picking a tissue required for an examination just by inserting and extracting the biopsy tool into and from a lesion region when picking the tissue. The catheter can pick a tissue required to diagnose and treat an examinee with a minimal invasion. Accordingly, it is possible to alleviate the examinee's pain and to prevent a perforation from occurring in the picked region when picking the tissue. In addition, according to the catheter of the invention, since the micro biopsy tool can be easily mounted and separated, the catheter can be semi-permanently used by continuously replacing the biopsy tool only.

Abstract: The present invention relates to a method of improving a 3D ultrasound color Doppler image through a post-processing. A method of processing an ultrasound image, includes the following steps: a) recognizing a target object from an inputted ultrasound image based on an object recognition algorithm using connectivity of the target object; b) setting at least one object region by using the connectivity of the recognized target object; c) calculating a structure matrix by using voxel gradients of the object region; d) calculating a diffusion matrix from the structure matrix; and e) acquiring a processed ultrasound image by applying the diffusion matrix and the voxel gradients to the inputted ultrasound image.

Abstract: A database query system is provided. The database cache system includes: a network library which processes an access request issued by the online game server by using an input output completion port (IOCP); at least one database connection module which provides a connector for reading data from the database or recording data to the database; a database cache which stores data read from the database by the database connection module; and at least one cache buffer which is allotted to an IOCP worker thread corresponding to a database query request issued by the online game server and stores data read from the database, which is to be transmitted to the online game server.

Abstract: A height adjustable folding work platform includes two footplates, a footplate folding portion that foldably connects the footplates, two legs, and two leg folding portions, each of which connect the leg to the outer end of the footplate. Each of the legs includes two support legs and a plurality of cross members that connect the support legs. The leg folding portion selectively engages with one of the cross members so that the height of the height adjustable folding work platform is adjusted.
