Abstract: The present disclosure relates to a cathode active material for an all-solid-state battery with a controlled particle size and a method for preparing the same. In particular, the cathode active material includes lithium and a transition metal, wherein the cathode active material has a single peak in the range of 1 ?m to 10 ?m as a result of particle size distribution (PSD) analysis.

Abstract: A packaging device including bumps and a method of manufacturing the packaging device are presented. In the method of manufacturing a packaging device, a dielectric layer that covers a packaging base is formed and a lower layer is formed over a packaging base including first and second connecting pads. A plurality of dummy bumps that overlaps with the dielectric layer is formed. A sealing pattern that covers the dummy bumps, filling areas between the dummy bumps, is formed. A lower layer pattern in which the plurality of dummy bumps have been disposed is formed by removing portions of the lower layer that are exposed and do not overlap with the sealing pattern.

Abstract: Provided are a method for preparing a polyetherketoneketone and a polyetherketoneketone prepared thereby, wherein, at the time of a polymerization reaction, nitrogen gas is blown into a liquid reaction medium while stirring, thereby quickly removing hydrochloric acid, which is a by-product generated during the reaction, and preventing aggregation of resin particles, thus suppressing the generation of scales.

Abstract: The surface of a gallium nitride single crystal substrate is processed, e.g., comprising steps by planarizing the top side and the bottom side of a gallium nitride original substrate positioned on a support bed; radiating light having wavelengths ranging from 370 to 800 nanometers (nm) onto the planarized gallium nitride original substrate; measuring transmittance of the gallium nitride original substrate; and confirming whether the transmittance is within the range of 65 to 90%. A gallium nitride single crystal substrate obtained through the method of processing the surface has high transmittance ranging from 65 to 90% measured using light having wavelengths of 370 to 800 nm. The thickness ratio (DLa/DLb) of the damage layers on the both sides of the gallium nitride single crystal substrate can be obtained within the range of 0.99 to 1.01.

Abstract: Disclosed herein is a mobile advertisement processing method. The method is performed by a mobile terminal and an advertisement server connected over a network to an application server for providing an application. An advertisement to be exposed on the application and an advertisement completion condition are set. Advertisement data to be played on the application is provided in response to a request of the application run in the mobile terminal. Notification of whether the user has recognized the advertisement is received through the application, and exposures of the advertisement are totalized. Accordingly, the present invention prevents users from getting tired with application-based mobile advertisements, and allows the users to positively respond to mobile advertisements, thus improving advertising effects.

Abstract: A portable memory device for use with a USB-supporting computer includes a USB connector, an integrated circuit memory for writing and reading data, and a USB interface, connected between the USB connector and the memory, for interfacing with the computer, and a housing for accommodating the memory and the USB interface. The memory device is used as a portable memory medium such as a floppy disk. The USB memory device is less dangerous of data loss caused by dusts or shock. Additionally, the USB memory device can be used as an electronic security key device of a computer or a computer-based system.

Abstract: An advertising system and method using a lotto game. The advertising system provides a user with a free-of-charge lotto game in payment for the exposure of advertising messages, enables the user having a lotto-game subscription coupon manufactured by an advertiser to enjoy the free-of-charge lotto game such that it can encourage the user to aggressively view the advertising messages of the advertiser by himself or herself, resulting in the maximum advertising effect of the desired advertisement.

Abstract: A method for upgrading firmware (F/W) of a wireless communications device is capable of updating F/W at all times through a simple process by transferring, directly and wirelessly, new firmware required for the wireless communications device from a base station. In the F/W upgrade method, a user's identification of the wireless communications device and information required for F/W upgrade are transferred to the corresponding base station, and the current mode of the wireless communications device is converted into an F/W upgrade mode according to whether or not the corresponding base station allows the upgrade, which is determined based on the transferred information. Then, F/W of the wireless communications device is wirelessly upgraded by the corresponding base station.

Abstract: An apparatus for controlling a disk player used for a computer system and a method therefor. The apparatus includes a disk information storing unit for storing disk position information, a disk information reading unit for reading information on the position of the disk in which the playing of the disk is stopped in the disk player, a controller for controlling the disk player such that the information of a disk stop position read from the disk information reading unit is stored in the disk information storing unit when the playing of the disk is stopped in the player, and the information stored in the disk information storing unit is read to begin playing of the disk from the stopped position when playing of the disk is resumed. When a reproduction operation of the disk is stopped, the disk ID number and stop position information is stored, and the playing of the disk is controlled to resume playing of the disk, with reference to the information.

Abstract: A communications card, PCMCIA card, with a retractable BNC connector receptacle built into one edge of the card. The BNC connector receptacle can be rectangular or have an X-shape and is thinner than the PCMCIA card when retracted. The retractable BNC connector receptacle allows the PCMCIA card to directly interface with an external BNC connector without using an adapter. Having a retractable receptacle makes it easier to store the PCMCIA card and built-in connector. This new communications card and BNC connector receptacle will increase the efficiency of computer use and will increase the ease of data transmission.
