Abstract: The present disclosure relates to a multi-organ model, and the multi-organ model of the present disclosure is excellent in culturing each organoid due to linkage between organoids and properties of hydrogel and can more accurately reflect the interactions between organs and the microenvironment in vivo. Also, the multi-organ model is further subjected to free fatty acid treatment and thus can more accurately mimic the phenotypes of non-alcoholic fatty liver. Accordingly, it is possible to analyze the effects of candidate drugs on peripheral organs.

Abstract: Disclosed are a functional photoresist for patterning a nanoparticle thin film including nanoparticles on a substate and a method of patterning a nanoparticle thin film using the functional photoresist, wherein the functional photoresist includes a photoactive compound (PAC); and a functional ligand that is bound to the surfaces of the nanoparticles and controls the physical properties of the nanoparticles.

Abstract: A method for recognizing an identification (ID) card of a user terminal using deep learning includes extracting an outline region of the ID card included in an input image using a first neural network model, modifying the ID card image of the image to a reference form using at least a partial value of the extracted outline region, and determining whether the modified ID card image is valid and recognizing text information in the valid ID card image. A recognition rate of the ID card may be increased by modifying an ID card image into a reference form using a trained neural network model.

Abstract: A lens spacer may be configured to maintain a gap between a first lens and a second lens arranged along an optical axis. The lens spacer may include a first film member having a ring shape and may include a plurality of first tabs and a plurality of first recesses disposed between adjacent ones of the first tabs. The first tabs may protrude from an inner circumferential surface of the first film member toward the optical axis. A second film member may have a ring shape and may include a plurality of second tabs and a plurality of second recesses between adjacent ones of the second tabs. The second tabs may protrude from an inner circumferential surface of the second film member toward the optical axis. The first and second film members may be arranged along the optical axis, and the second tabs may overlap respective ones of the first recesses.

Abstract: A zoom lens barrel assembly includes a first barrel, a second barrel, a lens barrier, and a transparent member. The first barrel supports at least one lens. The second barrel surrounds at least a portion of an outer surface of the first barrel, and supports the first barrel to protrude along an optical axis direction. The lens barrier is disposed on a front side of the first barrel, and is moved in a direction that intersects an optical axis to expose the at least one lens when the first barrel is protruded. The transparent member is disposed on a front side of the lens barrier, and prevents impurities from entering the first barrel.
