Abstract: The present disclosure relates to a high-strength Fe—Cr—Al—Ni multiplex stainless steel and a manufacturing method therefor. The multiplex stainless steel comprises 35 to 67 wt % of iron (Fe), 13 to 30 wt % of chrome (Cr), 15 to 30 wt % of nickel (Ni), and 5 to 15 wt % of aluminum (Al) and has a multiplex structure in which an austenite phase accounting for high ductility, a ferrite phase accounting for high strength, and an NiAl(B2) phase providing both strength and high-temperature steam oxidation resistance, exist in combination. The multiplex stainless steel can secure necessary fabricability and mechanical strength even if for/in a thin state, can maintain integrity as a structural member in a normal operation condition of a light-water reactor thanks to the formation of a chrome oxide layer thereon, and can form a stable oxide layer including alumina under a high-temperature steam environment, which is plausible in a high-temperature nuclear accident, thereby providing exceptionally improved resistance to serious accidents.

Abstract: A method for generating a trained model is provided. The method for generating a trained model includes: receiving a learning data; generating an asymmetric multi-task feature network including a parameter matrix of the trained model which permits an asymmetric knowledge transfer between tasks and a feedback matrix for a feedback connection from the tasks to features; computing a parameter matrix of the asymmetric multi-task feature network using the input learning data to minimize a predetermined objective function; and generating an asymmetric multi-task feature trained model using the computed parameter matrix as the parameter of the generated asymmetric multi-task feature network.

Abstract: An inspection apparatus inspects a pressure vessel using laser ultrasound. The apparatus includes an oscillation device that oscillates an excitation laser for exciting the pressure vessel and a conduit to guide the excitation laser oscillated from the oscillation device to inside the pressure vessel. The conduit is inserted into the pressure vessel with one conduit end located inside the pressure vessel and an opposite end located outside the pressure vessel. The apparatus includes a reflector at one conduit end inside the pressure vessel to reflect the excitation laser guided by the conduit and a detector that detects ultrasonic waves generated in the pressure vessel by the excitation laser reflected by the reflector by oscillating a receiving laser from outside of the pressure vessel. At least the conduit, reflector, or detector moves to correct an optical path of the excitation laser or the receiving laser.

Abstract: The present invention relates to a transition metal nitride support, a method of manufacturing the same, a metal catalyst and a platinum-alloy catalyst including the transition metal nitride support, and manufacturing methods thereof. The manufactured transition metal support prevents corrosion of the support and aggregation of the platinum catalyst, thereby exhibiting high oxygen reduction catalytic activity. Also, strong metal-support interaction (SMSI) can be stabilized, thus improving the durability of the catalyst. The transition metal support includes large pores uniformly distributed therein, thereby increasing the amount of the catalyst supported and minimizing mass-transfer resistance in a membrane- electrode assembly, increasing the performance of a polymer electrolyte membrane fuel cell. The metal catalyst includes platinum particles loaded on the transition metal nitride support, thus exhibiting superior durability and activity. The manufactured platinum-alloy catalyst decreases the use of expensive platinum, thus generating economic benefits and improving the inherent oxygen reduction performance.

Abstract: Various embodiments relate to an electronic device for supporting a finger pinch interaction using a return loss of a radio frequency signal and an operating method thereof. The electronic device is configured to measure a return loss of an antenna while radiating a radio frequency signal through the antenna and to detect whether a thumb and a finger touch each other within a predetermined distance from the antenna based on the measured return loss. Accordingly, there can be provided an interaction for the touch between the thumb and the finger.
