Abstract: Disclosed is a bulk block for manufacturing a prosthesis having high aesthetics and processability required for one-day dental prosthetic materials, which is a dental composite bulk block comprising a glass ceramic matrix and a polymer, wherein the glass ceramic matrix consists of an amorphous glass matrix and a crystalline phase dispersed in the glass matrix, the crystalline phase comprises as a main crystalline phase at least one selected from a leucite crystalline phase and a lithium disilicate crystalline phase, and has an average particle diameter of 0.01-1.0 ?m, and the polymer is included in an amount of 20-40 wt % with respect to the weight of the total bulk block. The bulk block has the advantages of improved mechanical properties, being capable of preventing microleakage, exhibiting excellent aesthetics, and enabling machining.

Abstract: A strain sensor may have a conductive elastic yarn including a first fiber having a predetermined length and a shape of a fiber yarn and a second fiber having electrical conductivity and a sheet shape. The strain sensor may have a pair of wiring members electrically connected to both ends of the conductive elastic yarn. The conductive elastic yarn, with the second fiber wrapped around the first fiber, is twisted in a coil shape.

Abstract: A method for transmitting specific data whose data format is unknown at a relay from a first blockchain network to a second blockchain network via the relay is provided. The method includes steps of: the relay (a) in response to detecting that a blockchain communication message for transmitting the specific data from the first blockchain network following a first data format to the second blockchain network following a second data format is generated, generating a relay message including the blockchain communication message and verification information; and (b) transmitting the relay message to the second blockchain network, thereby instructing the second blockchain network to (i) verify the relay message by using the verification information included in the relay message and (ii) convert the specific data included in the relay message into the second data format to generate converted specific data and then transmit the converted specific data to a receiving party.

Abstract: The present invention relates to a compound of dihydrophaseic acid 3?-O-beta-D-glucopyranoside for the prevention and treatment of osteoporosis. It was found that the D3G isolated from the Lycium root bark extract induces the activity of osteoblast differentiation while promoting the proliferation of pre-osteoblast, and promotes the bone remodeling by promoting the differentiation of both osteoblast and osteoclast when mixing and culturing pre-osteoblast which is the precursor of osteoblast, and monocyte which is the precursor of osteoclast. Therefore, the D3G of the present invention is expected to be useful as a pharmacological agent or functional food effective for the prevention and treatment of osteoporosis which is a disease caused by the abnormal balance of bone remodeling.
