Abstract: The present invention provides marble chips produced by hardening or molding a resin composition including a binder and a reactive monomer, wherein the binder comprises a halogenated alkoxylated diacrylate oligomer. The marble chips of the present invention can be formed into a uniform pattern, so that an artificial marble made using the marble chips of the present invention may have an outer appearance and texture similar to that of engineered stone.

Abstract: The present invention provides an inorganic artificial marble having excellent impact strength and weather resistance. The inorganic artificial marble can be a substitute for natural stone and used as an exterior finishing material.

Abstract: The present invention provides transparent chips with natural metal-like texture by coating silica-containing transparent chips with colored material, such as a metal powder, in a transparent resin as a base resin. The present invention also provides artificial stone with natural metal-like texture and patterns by mixing the colored material coated transparent chips and inorganic filler with a matrix resin. The artificial stone of the present invention can be prepared by mixing about 4 to about 24 parts by weight of inorganic filler and about 0.1 to about 5.0 parts by weight of the colored material coated transparent chips, per about 1 part by weight of the matrix resin. The colored material coated transparent chips can have a specific gravity of about 2.0 to about 2.65, while the matrix resin can have a specific gravity of about 2.2 to about 2.

Abstract: Artificial marble having a transparent amorphous pattern includes a base or matrix material portion and a transparent pattern portion. The pattern portion has a specific gravity or about 1.60 or more and is formed by hardening or curing a resin composition comprising a binder selected from halogenated urethane acrylates, halogenated epoxy acrylates and combinations thereof and an acrylic polymerizable monomer.

Abstract: Provided is an apparatus and method for searching for a WLAN in a portable terminal. The method includes, upon registering a WLAN, mapping and storing cell information on a present position and information on the registered WLAN; comparing the stored cell information with connected cell information when entering a mode concurrently supporting a cellular network and a WLAN in a state where a connection to the cellular network is made; and searching for a WLAN using the WLAN information mapped to the stored cell information, when the stored cell information is consistent with the connected cell information.

Abstract: A demand response (DR) system includes a DR control unit to generate different DR levels having different power rates for each power unit, and transmit a current DR level, and a household appliance to receive the DR level from the DR control unit, and differentially control energy output of a product in response to the received DR level so as to reduce power consumption of the product. As a result, the DR system reduces power consumption when power rates are high so as to reduce electricity bills.

Abstract: A demand response (DR) system, computer-readable medium and method are disclosed. The DR system controls a high-power-consumption load to be pre-operated or post-operated in a low-power-rate interval instead of a high-power-rate interval, and reduces an amount of power consumption required for a high-power-rate interval, resulting in reduction of power rates. In addition, limitation to household appliance operation is minimized, to greatly reduce inconvenience of a user.

Abstract: An article of artificial stone includes a first resin matrix and a plurality of artificial stone chips in the first resin matrix. The specific gravity of the artificial stone chips is the same as or similar to the specific gravity of the first resin matrix.
