Abstract: Provided is a method of operating a terminal. The method includes determining a profile item applicable to the profile view for the account based on an input received by the terminal and a coordinate indicating a position where the profile item is provided on the profile view. The method includes displaying the profile item on a screen of the terminal based on the determined profile item and the determined coordinate. The method includes receiving an input related to the profile item, and displaying a visual effect corresponding to the input on the screen.

Abstract: A computing resource management system using software modularization in a cluster computing environment in which computing devices are connected, including an application process running on each computing device and an algorithm processing process configured to run independently of the application process and perform task processing on the application process, the computing resource management system including: a task managing system configured to receive a task request message from an application process requiring a task from each computing device; a process managing system configured to confirm an algorithm processing process of computing devices connected to the cluster computing environment, and determine whether there is an algorithm processing process in an idle state to which the application process requested for a task will be assigned; and a performed managing system configured to confirm a result of an application process whose task is performed by the algorithm processing process.

Abstract: In a method for recovering lithium hydroxide from a lithium secondary battery, cathode powder is prepared from a cathode of the lithium secondary battery. A cathode active material mixture is prepared by mixing the cathode powder with a calcium compound. The cathode active material mixture is reduced to form a preliminary precursor mixture. A lithium precursor is recovered from the preliminary precursor mixture. Therefore, a lithium precursor can be obtained with high purity without a complicated leaching process or an additional process, which result from a wet-based acid solution process.

Abstract: A composition for enhancing protein strength according to the present invention contains an aminosilane compound capable of covalent binding with a protein of hair, scalp, skin, nails, leather, or textile, so that the protein and the amino silane compound form a covalent bond, and thus the composition can improve the protein strength enhancement effect and maximize the semi-permanent protein strength enhancement effect.

Abstract: The inventive concept provides a teaching method for teaching a transfer position of a transfer robot. The teaching method includes: searching for an object on which a target object to be transferred by the transfer robot is placed, based on a 3D position information acquired by a first sensor; and acquiring coordinates of a second direction and coordinates of a third direction of the object based on a data acquired from a second sensor which is a different type from the first sensor.

Abstract: An optical film for a display device, includes: a first refractive layer having an upper surface and a lower surface including first projections and second projections extending away from the lower surface in a first direction, the second projections having different heights than the first projections, the first projections having lateral sides with different angles of inclination that decrease in the first direction; and a second refractive layer disposed directly on the upper surface of the first refractive layer, the second refractive layer having a refractive index different from that of the first refractive layer.

Abstract: A display device includes a display portion including a first surface, from which light is emitted in a first direction, and a second surface opposite to the first surface, a first optical portion disposed on the first surface, and a second optical portion disposed on the first surface to be spaced apart from the first optical portion in a second direction crossing the first direction. Each of the first and second optical portions includes a multi-channel lens through which the light from the first surface passes, a first infrared light source, a first camera, and a first lens frame coupled to the multi-channel lens in the first direction to support at least a portion of the multi-channel lens. The first lens frame may include a first recess structure in which the first infrared light source is disposed and a second recess structure in which the first camera is disposed.

Abstract: Provided are a method and an apparatus for providing a secure message service. The method according to some embodiments includes inquiring a public key of a counterpart user to be invited to a chat room, generating an encryption key related to the chat room using the inquired public key and a private key of a chat room opening user, and transmitting the encryption key to be delivered to a terminal of the counterpart user.

Abstract: Provided are a pharmaceutical composition for preventing or treating inflammatory disease, autoimmune disease, graft rejection responses, or combinations thereof, the pharmaceutical composition including a compound represented by Formula 1, or a stereoisomer, derivative, solvate, or pharmaceutically acceptable salt thereof, and a method using the pharmaceutical composition. The pharmaceutical composition and the method can be used to effectively prevent or treat inflammatory disease, autoimmune disease, graft rejection responses, or combinations thereof.

Abstract: Disclosed are a natural soap composition having elasticity, viscoelasticity and ductility without containing polyvinyl alcohol (PVA) and borax, and a method of preparing the same. The soap composition does not contain a plastic material (PVA), borax, a fungicide, a plasticizer or the like, unlike conventional plastic clay toys, and is thus environmentally friendly and safe, and has a cleaning effect. In addition, the composition has the advantages of better elasticity, viscoelasticity and ductility than general soaps or other elastic soap compositions. In addition, even after the composition is molded into a particular shape, it can be transformed into a variety of shapes, can be used as a toy owing to the maximized tactile stimulation thereof, and provides effects such as psychological stability, stress relief and sensory development.
