Abstract: A method for preparing a tightly sealed 3D lipid structure and a tightly sealed 3D lipid structure prepared thereby is disclosed. The method allows for simpler and more convenient preparation of an artificial biomembrane structure on a substrate using a lipid material, by using a plurality of transparent microwells formed on the substrate, and observation inside the microwells. In addition, a spherical 3D artificial single bilayer structure may be sealed very tightly through a simple method of changing the frequency of an electric field applied vertically to the microwells having a lipid layer formed. Through this, a biomimetic 3D structure having the structural and/or functional characteristics of a cell membrane constituting a cell can be provided more effectively.

Abstract: Provided is a method of forming a dynamic maximal viewing zone (DMVZ) of an autostereoscopic display apparatus. The method includes rearranging viewpoint images for each three dimensional (3D) unit pixels of a certain period k when a viewer deviates in a depth direction from a designed viewing distance (DVD), wherein the certain period k is determined according to a distance by which the viewer deviates in the depth direction from the DVD.

Abstract: Disclosed is a zinc-imidazole complex mixed catalyst. Also disclosed are a method for preparing the zinc-imidazole complex mixed catalyst and a method for producing a methyl N-phenyl carbamate in high yield with high selectivity in the presence of the catalyst. The zinc-imidazole complex mixed catalyst can be reused due to its high reaction stability. In addition, the use of the zinc-imidazole complex mixed catalyst leads to a marked improvement in the production yield of a methyl N-phenyl carbamate with high selectivity.

Abstract: A method of multi-view deblurring for 3-dimensional (3D) shape reconstruction includes: receiving images captured by multiple synchronized cameras at multiple viewpoints; performing iteratively estimation of depth map, latent image, and 3D motion at each viewpoint for the received images; determining whether image deblurring at each viewpoint is completed; and performing 3D reconstruction based on final depth maps and latent images at each viewpoint. Accordingly, it is possible to achieve accurate deblurring and 3D reconstruction even from any motion blurred images.

Abstract: A plasmonic structure having an identifier pattern indicating a genuine product for preventing counterfeiting, falsification or reuse, includes a metal layer; a photoconversion pattern layer including a plurality of photoconverting nanoparticles disposed in a pattern on and in direct contact with the metal layer; a metal pattern layer including a plurality of metal particles disposed in a pattern on and in direct contact with the photoconversion pattern layer; and an adhesive film disposed on the metal pattern layer. An identifier pattern indicating a genuine product is easily identified even by visual inspection after irradiation with infrared light irradiation. The plasmonic structure is fundamentally impossible to re-assemble after deformation of the plasmonic structure caused by disassembly of a product or packaging container, thereby preventing counterfeiting, falsification or reuse.
