Abstract: A display device includes a display panel having a first non-folding region, a folding region, and a second non-folding region consecutively arranged in a first direction. The folding region is adjacent to the first and second non-folding regions and is foldable about a folding axis. A lower substrate is disposed under the display panel. The lower substrate includes a spacing portion and a pattern portion. The spacing portion overlaps the folding region on a plane. The pattern portion is spaced apart from the display panel by the spacing portion in a thickness direction of the display device. The pattern portion includes a plurality of holes.

Abstract: Provided is an encoding apparatus for integrally encoding and decoding a speech signal and a audio signal, and may include: an input signal analyzer to analyze a characteristic of an input signal; a stereo encoder to down mix the input signal to a mono signal when the input signal is a stereo signal, and to extract stereo sound image information; a frequency band expander to expand a frequency band of the input signal; a sampling rate converter to convert a sampling rate; a speech signal encoder to encode the input signal using a speech encoding module when the input signal is a speech characteristics signal; a audio signal encoder to encode the input signal using a audio encoding module when the input signal is a audio characteristic signal; and a bitstream generator to generate a bitstream.

Abstract: A sealing structure may include a lid including a first lid face, a second lid face opposite to the first lid face, and a fragile area between the first lid face and the second lid face, a cover including a first cover face facing the second lid face and covering the fragile area and a second cover face opposite to the first cover face, wherein a first distance between the second lid face and the first cover face is substantially equal to or less than a second distance between the first cover face and the second cover face, and a connector configured to connect the lid and the cover.

Abstract: A suture according to an embodiment of the present disclosure includes a first barb portion, a second barb portion, and a center portion which connects the first barb portion and the second barb portion to each other. Each of end portions of the first barb portion and the second barb portion may be formed so as to face the center portion, and a hole portion including a plurality of holes may be formed in at least one of the first barb portion, the second barb portion, and the center portion. The suture may show an excellent recovery and a lifting effect to be semi-permanently maintained and may have an excellent strength.

Abstract: A device for skin care, cosmetics and medical treatment according to an embodiment of the present disclosure includes a roller coupled with microneedles and a handle unit for movement coupled with the roller to move the roller. The handle unit for movement may include a roller coupling part to which the roller is detachably coupled, an elastic pressing part connected to the roller coupling part to adjust a width thereof, and a grip part extended from the elastic pressing part. Accordingly, the roller may be easily attached and detached.

Each of end portions of the first barb portion and the second barb portion may be formed so as to face the center portion, and a hole portion including a plurality of holes may be formed in at least one of the first barb portion, the second barb portion, and the center portion. The suture may show an excellent recovery and a lifting effect to be semi-permanently maintained and may have an excellent strength.

Abstract: A method for producing a suture includes a first step of heating a suture raw material under a set temperature condition, a second step of compression molding, by applying pressure, the heated suture raw material, and a third step of forming cut lines at a first edge and a second edge of the compression molded suture and forming, by applying tensile force, a barb part in the compression molded suture having the cut lines, wherein the cut lines are continuously formed at predetermined intervals while being inclined at a predetermined angle toward one direction or both directions of the first and second edges. Thus, a suture which enables a sutured part to show an excellent recovery and a lifting effect to be semi-permanently maintained and which has an excellent strength is produced.
