Abstract: Disclosed is a method of producing lithium sulfide (Li2S) without using hydrogen sulfide (H2S) gas. Particularly, the method of producing lithium sulfide (Li2S) includes preparing a starting material including a metal oxide by subjecting a mixed powder including an inorganic compound containing lithium and oxygen, a metal reducing agent, and sulfur (S) to synthesis reaction using mechanical force, preparing a mixed solution by mixing the starting material and a solvent, and obtaining a lithium sulfide (Li2S) powder by removing the metal oxide from the mixed solution and then performing drying.

Abstract: The present invention relates to a novel lappaconitine derivative and a pharmaceutically acceptable salt thereof, a preparation method therefor, and a medical use thereof using osteogenesis-promoting activity. The lappaconitine derivative induces the differentiation of stem cells into preosteoblasts, and increases bone density when administered to an osteoporosis animal model, and induces osteogenesis, and thus can be effectively used for preventing, alleviating, or treating bone-related diseases such as osteoporosis.

Abstract: The present invention pertains to a novel lappaconitine derivative, a method for producing same, and a pharmaceutical use thereof using osteogenesis-promoting activity. The lappaconitine derivative induces the differentiation of stem cells into osteoblasts, increases bone mineral density when administered to animal models of osteoporosis, and induces bone formation in animal models of bone fracture, and thus can be advantageously used for preventing, ameliorating, or treating bone-related diseases such as osteoporosis, as well as treating non-disease fractures caused by physical trauma.

Abstract: Provided is a method of image searching based on artificial intelligence (AI), the method including acquiring retrieved information, which includes at least one of a retrieved image and an image address, and a user query on the basis of a search result of an image search engine, detecting a keyword-category combination on the basis of a type of the acquired user query, determining whether cache data that matches the detected keyword-category combination exists, generating, in response to absence of the cache data that matches the keyword-category combination, an object-category combination through an AI technology based object detection on the acquired retrieved information.

Abstract: A semiconductor device including at least one drift region formed near a channel region on a substrate, a first buried insulating layer formed in the drift region, and a first reduced surface field region interposed between the first buried insulating layer and the drift region. Accordingly, the semiconductor device provides first reduced surface field regions arranged between drift regions and first buried insulating layers, thus having advantages of improved junction integrity, suitability for LDMOS transistors employing a high operation voltage and reduced total size.
