Abstract: A method of performing chatroom transition, performed by a user terminal is provided. The method may include: continuously displaying, while a screen of a first chatroom that is active is displayed on a user terminal, a first notification bar indicating at least one first new message occurring in a second chatroom; and activating the second chatroom and displaying a screen of the second chatroom, instead of the screen of the first chatroom, in response to a first user input to select the first notification bar.

Abstract: A method, which is performed by at least one processor, includes: displaying a currently running application list in response to a first user input; generating a recommended application set including one or more recommended applications for configuring a split screen for a first application included in the currently running application list; displaying the recommended application set for the first application at a position adjacent to the first application; selecting, based on a second user input, a recommended application in the recommended application set for the first application; configuring a split screen including the first application and the selected recommended application; and automatically displaying the split screen.

Abstract: The present invention relates to a composition for preventing or treating transplantation rejection or a transplantation rejection disease, comprising a novel compound and a calcineurin inhibitor. A co-administration of the present invention 1) reduces the activity of pathogenic Th1 cells or Th17 cells, 2) increases the activity of Treg cells, 3) has an inhibitory effect against side effects, such as tissue damage, occurring in the sole administration thereof, 4) inhibits various pathogenic pathways, 5) inhibits the cell death of inflammatory cells, and 6) increases the activity of mitochondria, in an in vivo or in vitro allogenic model, a transplantation rejection disease model, a skin transplantation model, and a liver-transplanted patient, and thus inhibits transplantation rejection along with mitigating side effects possibly occurring in the administration of a conventional immunosuppressant alone.

Abstract: It is disclosed a blood glucose prediction system and method using saliva-based artificial intelligence deep learning technique.

Abstract: The present invention relates to a polyester sound absorption material having improved moldability and decreased weight and a method of manufacturing a molded product using the same, and more particularly to a polyester sound absorption material, which is capable of integrally molding a skin member and a sound absorption material using a felt including a polyester base fiber, a low-melting-point polyester adhesive fiber and a polyester hollow fiber, without the need to attach an additional sound absorption pad onto a skin member.

Abstract: Provided are an electronic system of a real-time operating system, an operating method thereof, and an operating method for a memory device. The operating method comprising obtaining a call graph by performing static code analysis on at least one thread that corresponds to a task, obtaining a stack usage of the thread and a call probability for each node by performing runtime profiling of the call graph, allocating a threshold value of a stack size for a first memory area by taking into account the call graph, the call probability for each node, and the stack usage, expanding and storing a stack from the first memory area to a second memory area according to a comparison result between the threshold value and a stack usage of the first memory area and returning the stack to the first memory when execution is completed in the second memory area, wherein the electronic system comprises a memory device configured to include the first memory area and the second memory area.

Abstract: The present invention relates to an OPCPA apparatus. The OPCPA of the present invention includes an optical pulse stretcher (100) for outputting chirped laser light using odd-order dispersion (third-order dispersion is mainly used). A pump laser (200) outputs pump laser light. An OPA unit (300) receives the pump laser light and the chirped laser light (signal), amplifies the signal using the pump laser light, and generates an idler. An optical signal separation unit (400) separates output light of the OPA unit into the signal, the idler, and remaining light (pump). An optical pulse compressor (600) compensates for pulse chirping caused by odd-order dispersion that is imparted by the optical pulse stretcher, thus temporally compressing the signal and the idler, which overlap each other.
