Abstract: The present disclosure relates to an apparatus and method for fast refining segmentation for a V-PCC encoder. The apparatus may include a grid segmentation unit segmenting a coordinate space of a point cloud into grid units, and an edge cube search unit searching a cube containing one or more points among the cubes segmented into grid units and containing a segment boundary. The apparatus may also include a surrounding cube search unit searching an edge surrounding cube containing one or more points within a predetermined range from the edge cube, and a smooth score calculation unit calculating smooth scores for all the edge surrounding cubes and all the edge cubes. The apparatus may further include a projection plane index update unit obtaining a normal score based on the calculated smooth scores and updating a projection plane index of each point in the edge cube using the normal score.

Abstract: The present invention relates to a peptide with anti-inflammatory activity, wherein the peptide comprises SEQ ID NO: 1, the peptide has above 80% homology of amino acid sequence with above-mentioned sequence, or the peptide is the fragment of the above-mentioned peptides. The present invention also relates to an inflammatory composition comprising the above mentioned peptides. According to the present invention, a peptide comprising a sequence of SEQ ID NO: 1 has an outstanding efficacy in both suppressing inflammation and in prophylactic means. Therefore, the composition comprising the peptide of this invention can be used as anti-inflammatory pharmaceutical composition or as cosmetic composition, in turn, treating and preventing a variety of different types of inflammatory diseases.

Abstract: An infusion flow regulator includes: a main body having an inlet through which fluid is introduced and an outlet through which the fluid is discharged; and a rotary dial rotatably coupled to the main body, with a sealing member interposed therebetween, so as to regulate a flow rate of the fluid, in which the rotary dial includes a regulating flow path having a shape of a recessed groove in cross section with a first width and a first height, and the regulating flow path includes a first region in which the first width is constant and the first height is decreased, and a second region in which both the first width and the first height are decreased. By the aforementioned configuration, the infusion flow regulator for the fluid can accurately regulate the flow rate even in a region where the flow rate of the fluid is very small.

Abstract: The present invention relates to a process for producing tetrahydrofuran polymer or tetrahydrofuran copolymer by using heteropolyacid catalyst, and more particularly, to a process for producing tetrahydrofuran polymer by using hydronium ion water having a pH of 5.5 or less as a reaction initiator in the initiation step.

Abstract: A plasma display apparatus and a method of driving the plasma display apparatus are provided. The plasma display apparatus includes a plasma display panel including a first electrode and a second electrode, a first electrode driver, and a second electrode driver. The first electrode driver supplies a first falling signal of a voltage magnitude, that is more than a voltage magnitude of a scan signal supplied during an address period, to the first electrode before the supply of a rising signal with a gradually rising voltage in at least one subfield of several subfields of a frame. The second electrode driver supplies a second signal having a polarity opposite a polarity of the first falling signal to the second electrode during the supply of the first falling signal.

Abstract: The present invention relates to hepatitis B virus (hereinafter it refers to HBV) polymerase containing a histidine tag, RNase H enzyme derived from HBV polymerase and processes for preparation thereof.
