Abstract: Provided is a method for preparing a latex composition for dip forming, the method including: (a) preparing a monomer mixture including a conjugated diene-based monomer, an ethylenically unsaturated nitrile monomer and an ethylenically unsaturated acid monomer; (b) introducing starch, an emulsifier and an inorganic solvent into the monomer mixture; and (c) preparing a copolymer latex by introducing a polymerization initiator, wherein the copolymer includes the starch in a main chain thereof.

Abstract: A positive electrode including a positive electrode active material layer disposed on at least one surface of a positive electrode current collector, the positive electrode active material layer including a lithium transition metal phosphate, a fluorine-based binder, and a conductive material. The lithium transition metal phosphate includes a carbon coating layer formed on a surface thereof, and a ratio (B/A) of a total weight (B) of the fluorine-based binder to a total weight (A) of carbon of the conductive material and the lithium transition metal phosphate in the positive electrode active material layer is 0.7 to 1.7.

Abstract: An exemplary embodiment provides a method for preparing a latex composition for dip forming, the method including: (a) preparing a monomer mixture including a conjugated diene-based monomer, an ethylenically unsaturated nitrile monomer and an ethylenically unsaturated acid monomer; (b) introducing an additive including an inorganic solvent, an emulsifier and starch into the monomer mixture; and (c) preparing a copolymer latex by polymerizing the monomer mixture, wherein a content of the starch is 0.1 to 4.9 parts by weight with respect to 100 parts by weight of the monomer mixture.

Abstract: The present invention relates to a method and system for selling and buying items at auction using information about the purchase of items via an online shopping mall website. In order to sell and buy used items, a used item seller does not need to separately provide pieces of information about used items, and can perform a transaction for the used item using only a minimum number of inputs or actions, thus saving temporal and material costs caused by the disposal of used items. As a result, the present invention can offer convenience to the sellers of used items and can allow the buyers of used items to reasonably fix the states or prices of their desired used items and purchase relevant used items.

Abstract: A repeater for relaying data signals between two nodes is provided. The repeater includes a first signal processor that amplifies the received data signals, a path controller that transmits initial information of the received data signal through a first path to determine if the received data signal is from a specific local area and transmits data signals following the initial information through a second path to amplify the data signals following the initial information, a second signal processor that amplifies and transmits the data signal, and a data selection processor that allows the data signals following the initial information to be transmitted through the second path when it is determined using the initial information received that the received data signal is from the specific local area.

Abstract: A backlight unit includes a lamp to generate and radiate an ultraviolet ray, a light guide plate including a light receiving portion to receive the ultraviolet ray, an optical sheet disposed on the light guide plate to change the ultraviolet ray into a visible ray, the optical sheet including a fluorescent material, and a reflective sheet arranged under the light guide plate.

Abstract: A backlight unit and a liquid crystal display having the backlight are provided. The backlight unit includes a plurality of light emitting diode (LED) chips, a light guide plate for converting light generated from the LED chips into surface light, and a plurality of optical guide modules corresponding to the respective LED chips and disposed between the LED chips and the light guide plate.
