Provided are a high efficiency light emitting diode and a method for fabricating the same, in which a multi-layer reflector is laminated to a surface emission type light emitting diode to improve the efficiency of a light emitting diode. A high efficiency reflector is integrated on the light emitting diode using a dry etching process and a wet etching process. Although light produced from an active layer when applying a current thereto is emitted in several directions, the reflectors formed both sides of the active layer reflect the emitted light toward a surface of a semiconductor substrate, thus improving the light efficiency. Compared with the existing light emitting diode, the structure of the proposed light emitting diode is more efficient and therefore it can be used as a light source having low power consumption and high brightness. Also, the light emitting diode can be fabricated using the existing semiconductor process, thus reducing the complexity of the fabricating process.

An apparatus and method is provided for processing an application program-related event in a wireless terminal. In the apparatus, a memory stores character user interface (UI) images associated with application program-related events. An event collection part collects the application program-related events occurring in the wireless terminal, and generates an event message for identifying its associated application program-related event. An agent control part, including a plurality of specialists for processing the application program-related events, selects a specialist mapped to the event message, sets an alarm event for an application program-related event of the selected specialist, and upon arrival of an occurrence time of the alarm event, selects and outputs a character UI for information on the alarm event and processes user feedback information for an associated event in response to the feedback information received from a user. An agent expression part outputs a character and text mapped to the application program-related event and the feedback information.

The optimal direction-based flooding method for relaying a broadcast message for mobile ad-hoc networks comprises (a) an original source node selecting a first relay node; (b) selecting a message relaying direction into an area divided by a predetermined interval; (c) relaying the broadcast message by selecting the first relay node set for each message relaying direction; and (d) selecting a next relay node and relaying the broadcast message received by the previously selected relay node. Duplicated broadcast message transmissions, and competition and collision among the nodes to obtain transmission media, are reduced by transmitting the broadcast message using a minimum number of nodes in a mobile ad-hoc network including nodes having limited resources.
