Abstract: A device comprises a substrate, a plurality of emission portions disposed on the substrate and emitting light, a plurality of light sensing portions disposed on the substrate and sensing an incident light, a bank layer partitioning the plurality of emission portions and the plurality of light sensing portions, and a touch sensing layer disposed on the bank layer. The touch sensing layer comprises a first touch insulating pattern disposed on the bank layer and partitioning a light opening overlapping the plurality of light sensing portions and a touch electrode disposed on the first touch insulating pattern. A cross-sectional shape of the first touch insulating pattern has a reverse tapered shape having a width that decreases towards a top surface of the substrate.

Abstract: Disclosed are a method and apparatus for providing an instant messaging service associated with one or more item transactions. A first user interface screen associated with an item transaction may be provided in a chatroom interface of an executed messenger application. The first user interface screen may comprise an interfacing object associated with a list of user interface templates. Based on a user selection of the interface object and based at least one exposure condition associated with the list of user interface templates, at least one user interface template may be selected from the list of user interface templates for display in a second user interface screen of the executed messenger application. In a second user interface screen of the executed messenger application, a first user interface template of the at least one user interface template may be displayed.

Abstract: The present disclosure provides a mobile communications system line number sheet management device and method. Provided, according to one aspect of the present disclosure, is a line number sheet management device and method, for automating access network-related line number sheet management by automatically collecting and updating line number information, the line number information being collected from a mobile communications base station management server (mobile communications system management server) and a fronthaul management server. Provided, according to another aspect of the present disclosure, is a fronthaul device for: acquiring unique information of a base station by receiving an optical signal from any one of a radio unit (RU) and a digital unit (DU); and transmitting the unique information of the base station to a fronthaul management server.

Abstract: A stent for expanding a lumen of a body having a structural stability along the length of the stent, as well as a good expandable force. According to one embodiment of the present invention, the stent is made of a single length of a filament and includes zigzag sections, in which the filament is wound in a zigzag manner, disposed on both end portions of the stent; and a spiral section, in which the filament is wound in a spiral manner, disposed between the zigzag sections. The zigzag section includes a plurality of bands. Each of the bands includes a series of straight portions, peak portions, and valley portions, the peak and valley portions being integrally engaged with the straight portions, and each of the bands is disposed along a circumferential direction of the stent on a plane substantially perpendicular to a longitudinal axis thereof; and each valley portion of the bands is twisted with a peak portion of an adjacent band.
