Abstract: The present invention relates to a separator for an electrochemical device includes a porous polymer substrate, and a porous coating layer formed on at least one surface of the porous polymer substrate, wherein the porous coating layer contains an acrylic acid-based binder, an acrylamide-based binder, and inorganic particles, and wherein the porous coating layer contains about 90% by weight to 96% by weight of the inorganic particles based on the total weight of the porous coating layer, and a weight ratio of the acrylic acid-based binder and the acrylamide-based binder is about 3:7 to 7:3.

Abstract: A separator for an electrochemical device includes a porous polymer substrate, and a porous coating layer formed on at least one surface of the porous polymer substrate, the porous coating layer includes inorganic particles and a polymer binder, the inorganic particles include, on surfaces thereof, a coating layer of a polymer including an amine group, and at least a portion of the polymer binder is crosslinked with the polymer including the amine group.

Abstract: An electronic device is provided that includes a memory, a display that detects a force input based on an external pressure, and a processor electrically coupled with the memory and the display. The processor executes an application that is operable corresponding to the force input, controls to store history information in the memory on use of the electronic device, the history information being related to a forcing point, to which the force input is applied, on an execution screen of the application, and controls to output via the display the history information to an area adjacent to the forcing point if the force input to the forcing point occurs.

Abstract: Provided is a caffeoylalphaneoendrophin peptide derivative, and use thereof, as an anti-itching agent and an anti-atopic agent. More specifically, provided is a caffeoyl endorphin peptide derivative, which is applicable in a cosmetic material for anti-inflammatory use, such as for an atopic dermatitis treatment, and the like. The caffeoyl endorphin peptide derivative is safe for skin, has resistance to degradation by peptidases, and the like, and also has an excellent stability with respect to temperature change, and the like.
