Abstract: Provided are an operating method of a storage device and an operating method of a storage system including the storage device. An operating method of a storage device including a nonvolatile memory device and a storage controller includes storing, by the storage controller, a public key received from a first host, transmitting, by the storage controller, a random number to a second host in response to a host authentication start request from the second host that has obtained the public key and a private key corresponding to the public key, receiving, by the storage controller, a signature generated based on the private key and the random number from the second host, verifying, by the storage controller, the signature based on the public key, and changing, by the storage controller, a first device parameter according to a request from the second host in response to the signature being verified.

Abstract: A composition comprising dichloroacetic acid and glyoxylic acid, wherein, the content of glyoxylic acid is below 1000 pm, and the preparation method and application of the composition. A process for preparing the composition, comprising: mixing a dichloroacetic acid material having greater than 1000 ppm glyoxylic acid with a glyoxylic acid capture reagent, and a process for preparing oligonucleotides, comprising using the composition. It is found that glyoxylic acid is an impurity in commercially available DCA products, which may cause the oligonucleotides synthesis failure. Ion chromatography can be used to detect glyoxylic acid in dichloroacetic acid and accurately determine its concentration.

Abstract: A mask inspection method including the steps of obtaining an image of a mask including a first region having a plurality of first openings, and a second region having a plurality of second openings, sectioning the image into a first partial image corresponding to the first region and a second partial image corresponding to the second region, respectively, inspecting the first region of the mask based on the first partial image, and inspecting the second region of the mask based on the second partial image.

Abstract: The present invention relates to a novel compound exhibiting anti-inflammatory activity, and the compound of the present invention plays a key role in the generation of pro-inflammatory cytokines, thereby having excellent inhibitory activity against p38 MAPK, which is known to cause inflammatory diseases, and thus can be effectively used as an agent for treating inflammatory diseases.

Abstract: A semiconductor device may include lower metal wirings on a substrate, a first upper insulating interlayer on the lower metal wirings, a first upper wiring including a first upper via in the first upper insulating interlayer and a first upper metal pattern on the first upper insulating interlayer. The semiconductor device may also include a second upper insulating interlayer on the first upper insulating interlayer, an uppermost wiring including an uppermost via in the second upper insulating interlayer, an uppermost metal pattern on the second upper insulating interlayer, and an oxide layer for supplying hydrogen on the second upper insulating interlayer. The lower metal wirings may be stacked in a plurality of layers. The oxide layer for supplying hydrogen may cover the uppermost wiring. A thickness of the uppermost via may be less than 40% of a thickness of the uppermost metal pattern.

Abstract: Aspects of the present disclosure relate to version control. A version control server receives, from a client device, a request for making changes to a portion of data stored in a data store. The version control server verifies that the client device has permission to make the changes to the portion of the data stored in the data store. The version control server updates, using a version control servlet, the data store according to the request. The version control sever creates, forks, merges or deletes, using a repository management API (application programming interface), a repository and/or the files in the repository in the data store based on the request. The version control server triggers, using the repository management API, one or more webhooks in response to the request.
