Abstract: A method of preparing a carbon fiber including: preparing a precursor fiber for preparing a carbon fiber; and stabilizing the precursor fiber. The stabilization of the precursor fiber includes a first stabilization phase, a second stabilization phase, a third stabilization phase, and a fourth stabilization phase, which are set at four different temperatures between a temperature at which heat starts to be generated from the stabilization reaction of the precursor fiber and a temperature at which the generation of heat is maximized. Ozone gas is input while at least one phase of the third stabilization phase and the fourth stabilization phase is carried out.

Abstract: Provided are apparatuses, a non-transitory computer-readable medium or media, and methods for supporting predicting of vascular disease using a fundus image of a subject. In certain aspects, disclosed a method including the steps of: extracting a feature information from a first fundus image of the subject based on a machine learning model; generating a second fundus image having a feature which is corresponding to the feature information by mapping a saliency factor to the first fundus image; and displaying the first fundus image and the second fundus image on a display device.

Abstract: A display device includes: a substrate; a display area including pixels arranged on the substrate; a first area disposed at one side of the display area; a second area including pads arranged on the substrate; a bending area disposed between the first area and the second area; and a fan-out line disposed in the first area, the bending area, and the second area. The fan-out line includes: a plurality of sub-routing lines arranged in the first area and electrically connected to each other; and a plurality of sub-pad lines arranged in the second area and electrically connected to each other. The number of the plurality of sub-routing lines is greater than the number of the plurality of sub-pad lines.

Abstract: A method of dynamically managing and sharing database in a mobile communication terminal and a server system is provided. By installing applications such as a database system and a user interface programs in the mobile communication terminal, a user forms a database arbitrarily in a form of his/her own preference, input data there, and forms a user interface in a form of their preference. Also, the data managed in the mobile communication terminal may be stored and managed in a mobile communication server system through a wireless network or in a computer through a wired network. The user can download database template a provider provides to the mobile communication terminal from the mobile communication server, use them without generating the database structure for him/herself, and graphs and numerical expressions the user produced using the data of database may be included.

Abstract: A door opening and closing device adapted for use at reinforce glass door or front door for gentle and quick swivel when a door is opened and for slow rotation when the door is closed, wherein the device comprises: a shaft rotatably supporting a door and coupled to the door for integral rotation with the door; a piston inserted to a circumference of the shaft so as to vertically move along a lengthwise direction of the shaft; a connector for connecting the shaft with the piston for the piston to move vertically in response to rotary movement of the shaft; a housing for receiving therein the shaft and the piston and having an upper chamber and a lower chamber partitioned by the piston, each chamber filled with operation fluid; a first fluid passage formed at an inner wall surface of the housing for communicating the upper chamber with the lower chamber; and a check valve mounted at the piston for being opened when the piston is upwardly moved to allow the operation fluid in the upper chamber to move to the low
