Abstract: Disclosed is a positive electrode for a lithium-sulfur battery, including a sulfur-carbon composite as a positive electrode active material. The sulfur-carbon composite includes a porous carbonaceous material having a high specific surface area, and the total pore volume in the carbonaceous material and a volume of pores having a specific diameter are controlled to specific ranges. Also disclosed is a lithium-sulfur battery using the sulfur-carbon composite. The lithium-sulfur battery shows reduced initial irreversible capacity and improved output characteristics and life characteristics.

Abstract: Disclosed herein are an adhesive protective film, an optical member including the same, and an optical display including the same. An adhesive protective film is formed of a composition including a (meth)acrylic binder derived from a monomer mixture including: an alkyl group-containing (meth)acrylic monomer; and at least one selected from among a hydroxyl group-containing (meth)acrylic monomer, a carboxyl group-containing (meth)acrylic monomer, and a polysiloxane (meth)acrylate, the adhesive protective film having an initial peel strength of about 100 gf/inch or less and a peel strength decrease rate of about 50% or less, as calculated according to Equation 1.

Abstract: A positive electrode for a lithium-sulfur battery is provided. The positive electrode includes a positive electrode active material comprising a first and second sulfur-carbon composites respectively comprising a first and a second carbonaceous materials having a different specific surface area and pore volume from each other, and provides reduced initial irreversible capacity and improved output characteristics and life characteristics of a secondary battery.

Abstract: A method for preparing a sulfur-carbon composite including a step of pretreating a carbon material is provided. The method is capable of removing water and other impurities from the carbon material effectively, and the sulfur-carbon composite obtained by the method used as a positive electrode active material of a lithium-sulfur battery provides improved sulfur supportability and over-voltage performance of the lithium-sulfur battery, reduced initial irreversible capacity of the positive electrode active material, and improved output characteristics and life characteristics.

Abstract: The present invention relates to a method for manufacturing non-slip socks, which arranges and presses a fabric to which a grapping member is bonded at the inside of the sock and then arranges and presses the fabric to which the grapping member is bonded at the outside of the sock. Here, accuracy of positions of the grapping members at the inside and the outside of the sock may increase by using a unit for guiding a position of the fabric, and productivity may improve.

Abstract: The present invention relates to an apparatus for manufacturing non-slip socks, in which a groove is formed in a mold rotating along a rotation table, and which includes a guide device at one side thereof to arrange fabrics at an exact position on the inside and the outside of the sock and maintain a state in which grapping members at the inside and the outside of the sock are exactly alternately arranged.

Abstract: A non-slip shoe wear has a non-slip part on each of an inner surface and an outer surface. The non-slip shoe wear can prevent an injury to the skin while maintaining a non-slip function by alternately arranging a non-slip part of an inner surface and a non-slip part of an outer surface.

Abstract: The present invention relates to a non-slip footwear having a cushion separation part, in which a non-slip material is formed on an inner surface and an outer surface of a bottom of a footwear such as a sock, wherein the non-slip material of the inside and the outside are arranged alternately and a cushion separation part is formed therebetween such that maintenance of a non-slip function and prevention of skin injury are smoothly performed.

Abstract: Disclosed is a non-slip shoe wear having a non-slip part on each of an inner surface and an outer surface, particularly, a non-slip shoe wear that can prevent an injury to a skin while maintaining a non-slip function by alternately arranging a non-slip part of an inner surface and a non-slip part of an outer surface.

Abstract: Provided are a connection error detecting apparatus and method. The connection error detecting apparatus, which detects connection errors for each rating of a smart meter, comprises: a parameter calculating unit for calculating connection error detecting parameters including an actual three-phase voltage value, an actual three-phase current value, an effective amount of three-phase power, and an ineffective amount of three-phase power; and a connection error determining unit for setting connection error criteria for detecting connection errors for each rating of the smart meter, and detecting the connection errors for each rating by determining whether or not any one of the connection error detecting parameters satisfies the connection error criteria.
