Disclosed is a show case capable of managing and displaying objects stored therein. A show case according to one aspect of the present disclosure is a show case having an accommodation space in which an object is stored, and includes: a body; a moving body configured to form the accommodation space together with the body and including a transparent window; a blowing part configured to circulate air in the accommodation space; a first illumination configured to illuminate an object placed on a bottom surface of the accommodation space; a second illumination configured to illuminate a rear surface of the accommodation space; an input part to which an image of the object accommodated in the accommodation space is input; and a controller configured to recommend a type of second illumination to a user depending on the image input to the input part.

Show case

A display device according to an embodiment includes a display panel and a protection layer that is disposed on the display panel, wherein the protection layer includes: a first protection layer; a metal layer that overlaps the first protection layer and includes a hole; and an adhesive layer disposed between the first protection layer and the metal layer. The adhesive layer includes a first area disposed between the first protection layer and the metal layer, and a second area and a third area that are disposed in the hole, wherein a peeling strength of the second area and a peeling strength of the third area are different from each other.

Display device

Disclosed are a speech processing method and a speech processing apparatus in a 5G communication environment through speech processing by executing embedded artificial intelligence (AI) algorithms and/or machine learning algorithms. The speech processing method includes determining a temporary pause of reception of a first spoken utterance, outputting a first spoken response utterance as a result of speech recognition processing of a second spoken utterance received after the temporary pause, determining, as an extension of the first spoken utterance, a third spoken utterance that is received after outputting the first spoken response utterance, deleting, using a deep neural network model, a duplicate utterance part from a fourth spoken utterance that is obtained by combining the first and the third spoken utterance, and outputting a second spoken response utterance as a result of speech recognition processing of the fourth spoken utterance from which the duplicate utterance part has been deleted.

Speech processing method and apparatus therefor

Disclosed are a speech processing method and apparatus therefor which execute an installed artificial intelligence algorithm and/or machine learning algorithm to perform speech processing in a 5G communication environment. The speech processing method may include determining a temporary pause of reception of a first spoken utterance, outputting a first spoken response utterance as a result of speech recognition processing of a second spoken utterance received after the temporary pause, determining, as an extension of the first spoken utterance, a third spoken utterance received after outputting the first spoken response utterance, deleting a duplicate utterance part from a fourth spoken utterance that is obtained by combining the first and the third spoken utterance, when performing speech recognition processing on the fourth spoken utterance, and outputting a second spoken response utterance as a result of speech recognition processing of the fourth spoken utterance from which the duplicate utterance part has been deleted.

A method of preparing a biodegradable polyester resin is provided. The method of preparing a biodegradable polyester resin includes: (a) synthesizing the biodegradable polyester resin having a reheating crystallization initiation temperature (T), a reheating crystallization peak temperature (T), and a reheating crystallization end temperature (T); and (b) crystallizing the biodegradable polyester resin synthesized in step (a) by cooling the resin from a temperature of Tto a temperature of Tand then maintaining the resin at a temperature of Tfor a time of t. Thus, the biodegradable polyester resin with improved solidification rate may be obtained.

Method for preparing biodegradable polyester resin

The present invention provides a method of preparing a polyester-based polymer and a polyester-based polymer prepared by the method. The method of preparing the polyester-based polymer includes a prepolymerization step of polymerizing a dicarboxylic acid compound (A), a diol compound (B), and an aromatic branching agent (C) at 160-220&#xb0; C. to produce a prepolymer; and a condensation polymerization step of performing a condensation polymerization of the prepolymer at 200-250&#xb0; C., under a vacuum pressure of 0.1 to 2 Torr.

Method for preparing biodegradable polyester copolymer

There are provided a resin composition for foaming including a biodegradable resin and a foamed article made thereof. The resin composition for foaming according to the present invention includes an ethylene-vinyl acetate resin, a biodegradable polyester resin containing a monomer of a double bond compound, a cross-linking agent, a co-crosslinking agent, a filler, and a foaming agent. In the resin composition, the double bond in the biodegradable polyester resin can be chemically cross-linked to the ethylene-vinyl acetate resin by a cross-linking agent, so that a compatibility with the ethylene-vinyl acetate resin can be improved, processability (mold releasability) during a mixing and melting process can be improved, and a foaming property and a mechanical property of a foamed article can be remarkably improved.

Resin composition for foaming containing biodegradable resin, and foam manufactured therefrom

There is provided a method of preparation for a biodegradable co-polyester, the method including: forming an oligomer through a primary esterification reaction between a hydroxy group of an aliphatic dihydroxy compound and a carboxylic group of an aliphatic dicarboxylic acid compound; performing a secondary esterification reaction between the formed oligomer and an aromatic dicarboxylic acid compound; and performing a polycondensation reaction in a vacuum, in which sequentially divided addition of the aromatic dicarboxylic acid compound is performed and the weight ratio of the aromatic dicarboxylic acid compound with respect to the oligomer for each time of the sequentially divided addition is from 2:8 to 5:5. The method efficiently increases a solubility of aromatic dicarboxylic acid, thereby increasing a reaction rate and reducing a side reaction.
