Abstract: A dielectric based metasurface hologram device includes: a substrate layer provided at a lowermost portion of the dielectric based metasurface hologram device; and a dielectric layer forming a geometric metasurface on the substrate layer. The substrate layer includes a plurality of unit cells which are continuous, and the dielectric layer includes a plurality of nano-structures which are disposed with a predetermined distance therebetween. The single nano-structure is disposed on the unit cell, and a hologram image is formed when an incident light from a light source is reflected by the nano-structure so that a phase of the light is controlled.

Abstract: Provided are a wavelength converting particle, a method for manufacturing a wavelength converting particle, and a light-emitting diode containing a wavelength converting particle. The wavelength converting particle comprises an organic/inorganic/hybrid perovskite nanocrystal that converts a wavelength of light generated by an excitation light source into a specified wavelength. Accordingly, it is possible to optically stabilize and improve color purity and light-emission performance without changes in a light-emitting wavelength range.

Abstract: Provided are: a light-emitting layer for a perovskite light-emitting device; a method for manufacturing the same; and a perovskite light-emitting device using the same. The method of the present invention for manufacturing a light-emitting layer for an organic and inorganic hybrid perovskite light-emitting device comprises a step of forming a first nanoparticle thin film by coating, on a member for coating a light-emitting layer, a solution comprising organic and inorganic perovskite nanoparticles including an organic and inorganic perovskite nanocrystalline structure. Thereby, a nanoparticle light emitter has therein an organic and inorganic hybrid perovskite having a crystalline structure in which FCC and BCC are combined; forms a lamella structure in which an organic plane and an inorganic plane are alternatively stacked; and can show high color purity since excitons are confined to the inorganic plane. In addition, it is possible to improve the luminescence efficiency and luminance of a device by making perovskite as nanoparticles and then introducing the same into a light-emitting layer.

Abstract: The present invention relates to: a transgenic Caenorhabditis elegans in which a glutamine tRNA 5′ terminus-derived fragment (Gln 5′-tsRNA) is overexpressed; a preparation method therefor; and a method for screening for aging-associated factors by using the transgenic Caenorhabditis elegans. A transgenic Caenorhabditis elegans model provided in the present invention is an animal model in which Gln 5′-tsRNA is overexpressed such that aging is inhibited. When the model of the present invention is used, anti-aging mechanisms can be easily investigated, thereby significantly contributing to various research fields such as that of developing new anti-aging drugs and screening for age-inducing materials.

Abstract: Disclosed is a method of manufacturing a surface-modified polymer film, including forming a hydroxyl group (—OH) on the surface of a polymer film by subjecting the polymer film to light irradiation and surface treatment with a photoacid generator. The polymer film can be introduced with a hydroxyl group (—OH) group using a photoacid generator, thereby modifying the surface of the polymer film without damage to the polymer film. Also, an organic electronic device including the surface-modified polymer film can be improved in electrical characteristics and stability.

Abstract: Provided herein are a pharmaceutical composition for preventing or treating a stress-related disease, which includes the DISC1 protein or a gene encoding the DISC protein, and a method of screening a material for preventing or treating the stress-related disease. As a result of studying the association between DISC1 and psychological stress, the inventors of the present disclosure verified the function of DISC1 in downregulating ER-mitochondria Ca2+ transfer induced by stress hormone-mediated oxidative stress by competitively inhibiting the binding of IP3 to inositol 1,4,5-trisphosphate (IP3) receptor type1 (IP3R1) by binding to the IP3R1 at the MAM, and an acting site of DISC1, and this provides a model of intracellular calcium response to physiological stress, and DISC1, a stress modulating substance, and the model may be usefully used in related fields for the prevention and treatment of stress-related diseases.
