Abstract:
A channel search method for a vertical handoff in a wireless network environment is provided, the channel search method including: collecting channel information from a first terminal which is provided with a wireless local area network (WLAN) service via a channel connection with a WLAN node; and determining a channel search order for a channel connection between a second terminal and the WLAN node by using the collected channel information. A channel search system for a vertical handoff in a wireless network environment is also provided, the channel search system including: a channel information collection unit for collecting channel information from a first terminal which is provided with a WLAN service via a channel connection with a WLAN node and a search order determination unit for determining a channel search order for a channel connection between a second terminal and the WLAN node by using the collected channel information.
Abstract:
Provided is a method of controlling a home hub in a virtual group that may provide a geographical boundary about the virtual group by associating an identifier of a network of a virtual group included in an access point list with a name of the virtual group and a name of the home hub managing the virtual group, and may provide a terminal which moves to a visited virtual group with information about a network of the visited virtual group, thereby facilitating recognition of a virtual group and content sharing.
Abstract:
Emoticon message composition is supported in a portable terminal. An edit window in the form of a lattice is displayed for message composition. During special character input selection, a list window including a plurality of special characters is displayed in the edit window. The list window is arranged such that a plurality of lines are shown in the edit window. The special characters displayed in the list window are arranged in a sequence of being stored in a queue that includes one of a special character queue for a message recipient or a basic special character queue.

Abstract:
Disclosed herein is a polar nematic liquid crystal assembly. The liquid crystal assembly comprises 5˜7.5% by weight of a dopant having the structure of Formula 1 below: (wherein X is an alkyl, alkenyl or heteroalkyl group having three or more carbon atoms) and 92.5˜95% by weight of smectic liquid crystal molecules having a linear alkyl chain wherein the N-bonding moiety of the dopant is spontaneously bonded to the alkyl chain of the smectic liquid crystal molecules to induce macroscopic spontaneous polarization in a particular direction.
Abstract:
Disclosed are a method of forming metal wiring and metal wiring formed using the same. The method includes printing wiring using an ink composition including metallic nanoparticles and dispersants maintaining dispersion of the metallic nanoparticles, performing a first firing process of firing the wiring under vacuum or in an inert atmosphere to suppress grain growth, and performing a second firing process of firing the wiring with the vacuum or inert atmosphere released, to accelerate grain growth. The method of forming metal wiring induces abnormal grain growth by rapidly removing dispersants, capable of inducing the growth of metallic nanoparticles, at a temperature at which the growth force of the metallic nanoparticles is high, in the process of firing the metallic nanoparticles. Accordingly, the metal wiring has a coarse-grained structure containing metallic particles with a large average particle size, and the electrical and mechanical characteristics thereof can be enhanced.

Abstract:
A queue management method of an access network device includes receiving a packet, determining feasibility of a packet transmission within a delivery deadline allowed from a destination if the received packet is for real-time transmission, storing the packet in the transmission queue and transmitting the packet in sequential order of the storage when the packet transmission within the delivery deadline is feasible, and dropping the packet instead of storing the packet in the transmission queue when the packet transmission is determined infeasible. Accordingly, resources required for the packet transmission are saved.
