    Abstract: Provided is a handover method of a wireless communication system using a hierarchical cellular scheme. In the method, signal quality of a serving node is measured, so that whether to start scanning for a handover is determined. When the scanning for the handover starts, signal qualities of a serving cell including the serving node and one or more neighbor cells are measured through a first preamble including a first identifier for distinguishing a cell. An intra-cell handover or an inter-cell handover is selected using the signal qualities of the serving cell and the neighbor cells. Therefore, a terminal can easily distinguish between the inter-cell handover and the intra-cell handover, and an overhead during a handover can be reduced because an intra-cell handover procedure is simplified.

    Abstract: The present invention relates to a nano-scale MOS device having a saddle structure. Particularly, the invention relates to a high-density, high-performance MOS device having a novel structure capable of improving the scaling-down characteristic and performance of the MOS device, in which a channel and gate structure is formed in the shape of a saddle. The inventive MOS device is mainly characterized in that a channel region is recessed, a gate insulating film and a gate electrode are formed on the surface and sides of the recessed channel, and the gate electrode is self-aligned with the recessed channel. Namely, in the disclosed MOS device, a portion of the insulating film around the recessed channel is selectively removed to expose the surface and sides of the recessed channel. According to the present invention, the scaling-down characteristic of the device is excellent and current drive capability is greatly increased since a channel through which an electric current can flow is formed on the surface and sides of the recessed channel. Also, the ability of the gate electrode to control the channel is enhanced. Accordingly, the invention can improve device characteristics.

    Abstract: A drum washing machine and washing method are provided. The washing machine directly sprays water to laundry inside the drum through a nozzle unit. The method includes passing some water through a detergent container and directly spraying some water to the inside of a drum through a nozzle unit such that a high concentration of detergent bubbles is generated while applying a force to the laundry. The washing machine includes a cabinet, a tub inside the cabinet, a drum inside the tub, a door on the cabinet, a diaphragm, and a nozzle unit installed so interference with the door is avoided and to receive water directly from an external source to spray water inside the drum during a washing cycle and a rinsing cycle. The nozzle unit adjusts water jetting according to a displacement of an actuator installed inside the nozzle unit.
