Abstract: The present disclosure relates to a portable printer including a main body in a portable form which is capable of accommodating a cartridge having a nozzle for delivering a printing material to a target having a soft or hard surface, a seating part which is provided to be exposed to an outside from a lower portion of the main body to face the surface of the target and at least partially surrounds the nozzle, a roller provided respectively at the front and rear of the nozzle at the lower portion of the main body with respect to a direction in which the main body moves along the surface of the target to deliver the printing material to the target, and a printing adjustment unit configured to adjust a height difference between the nozzle and the roller to adjust a height difference between the nozzle and the surface of the target.

Abstract: A method of performing collective communication in a collective communication system includes processing nodes, including: determining whether a command message, regarding one function among a broadcast function, a scatter function, and a gather function, is generated by a processor; determining a transmission order between the processing nodes by giving transmission priorities to processing nodes that do not communicate, based on a status of each of the processing nodes if it is determined that the command message regarding the one function among the broadcast function, the scatter function, and the gather function, is generated by the processor; and performing communication with respect to the command message based on the determined transmission order.

Abstract: A mobile terminal supporting detachable memory cards and a method for managing the detachable memory cards attached to the mobile terminal is provided. The detachable memory card management method of the present invention includes displaying, if at least two memory cards are detected, icons representing the memory cards on an idle mode screen, detecting selection of at least one of the icons, and creating files, stored in a source memory card represented by one of the selected icons, in a destination memory card represented by another icon. The detachable memory card management method of the present invention is capable of displaying the card icons representing the memory cards attached to the mobile terminal on the idle mode screen such that the user can identify the attached memory cards.

Abstract: A hardware device for executing conditional instructions out-of-order and the execution method. An architecture is provided, enabling the hardware device such as a processor supporting the conditional instruction and a computer system to execute the instruction out-of-order. To this end, a conditional execution buffer is provided, and a register of a destination operand of the conditional instruction is renamed to another register. Hence, the hardware device using the conditional instruction can carry out the out-of-order execution, and the execution speed of the hardware device can be greatly improved.
