Abstract: A method of manufacturing a cathode active material for a lithium secondary battery according to embodiments of the present invention includes performing a first heat treatment on a first mixture of a transition metal precursor and a lithium precursor at a first calcination temperature to obtain a preliminary lithium-transition metal composite oxide particle; and performing a second heat treatment on a second mixture obtained by adding the lithium precursor to the preliminary lithium-transition metal composite oxide particle at a second calcination temperature which is lower than the first calcination temperature to form a lithium-transition metal composite oxide particle.

Abstract: The present invention relates to a pharmaceutical composition containing ?-lapachone as an active ingredient for prevention or treatment of cholestatic liver disease, and can provide agents for effectively preventing and treating cholestatic liver disease.

Abstract: Proposed are a non-aqueous freestanding ion conductive gel for application to an electrolyte of a lithium secondary battery and a preparation method thereof. The non-aqueous freestanding ion conductive gel including: a matrix including a hydrophobic polymer famed through polymerization of monomers having an unsaturated double-bond; a domain dispersed in the matrix and including a hydrophilic ionic liquid; and a surface active layer including an ionic liquid having surface activity, in which a portion of a hydrophobic segment in a chain of the ionic liquid having surface activity is positioned in the matrix, and a portion of a hydrophilic segment in the chain is positioned in the domain. The gel has high ionic conductivity, high lithium ion transference number, and excellent mechanical strength.

Abstract: This present invention relates to novel compounds, isomer thereof or pharmaceutically acceptable salts thereof as vanilloid receptor (Vanilloid Receptor 1; VR1; TRPV1) antagonist; and a pharmaceutical composition containing the same. The present invention provides a pharmaceutical composition for preventing or treating a disease such as pain, migraine, arthralgia, neuralgia, neuropathies, nerve injury, skin disorder, urinary bladder hypersensitiveness, irritable bowel syndrome, fecal urgency, a respiratory disorder, irritation of skin, eye or mucous membrane, stomach-duodenal ulcer, inflammatory diseases, ear disease, heart disease and so on.

Abstract: The present invention relates to a high-voltage gas circuit breaker, and there is provided a gas circuit breaker including a movable arc contact and a fixed arc contact engaged with the movable arc contact; a cylinder rod coupled with the movable arc contact; an insulating rod connected to the cylinder rod through a link mechanism in which an end thereof is connected to an operating mechanism; and an ejection nozzle for ejecting an arc-extinguishing gas between the movable arc contact and the fixed arc contact, wherein the link mechanism is reduced in a length direction of the insulating rod to pull the cylinder rod to a side of the insulating rod when the insulating rod is moved apart from the cylinder rod.

Abstract: Provided herein is a cancer detection and treatment instrument comprising: a first conductive plate; a second conductive plate which is opposed to the first conductive plate and has a first opening; a first signal line disposed between the first conductive plate and the second conductive plate; a first contact member of which one end is exposed through the first opening and of which the other end is connected to the first signal line; a dielectric portion filled between the first and second conductive plates and the first signal line; and a conductive layer surrounding both side surfaces and a front end surface of the dielectric portion which are exposed. Therefore, it is possible to accurately detect cancer by the use of the ultrahigh-frequency signal and to treat a diseased portion without damaging tissues around the diseased portion.
