A power control method of a Central Processing Unit (CPU) in a multi-core system. The power control method includes acquiring current usage information of the CPU and system information, estimating a CPU usage of a next time interval based on the acquired current usage information, calibrating the estimated CPU usage of the next time interval based on the acquired system information, and determining a power control mode based on at least one of the acquired system information and the calibrated CPU usage of the next time interval.

As to the method for fabricating a member of a vehicle, after a member for the vehicle having high-rigidity of martensite organization is fabricated by a hot stamping forming, the martensite organization is transformed to a ferrite having a low-rigidity partially and improved toughness or to a metal organization heat treated by tempering process through induction heating or secondary heat treatment using laser beam of conduction area, and thereby collision absorption performance is improved by stabilizing the absorption directivity of the collision energy without additional reinforcement.

The present invention relates to an antenna matching method and apparatus of a mobile terminal, and the antenna matching method of the present invention includes configuring a predetermined matching value for an antenna corresponding to a channel selected in broadcast reception mode and adjusting, when reception performance is degraded on the channel, the matching value. According to the present invention, it is possible to support adaptive control for optimizing the frequency matching characteristic according to the variation of the antenna performance using control signal. As a consequence, it is possible to provide the mobile terminal with optimal signal reception environment.

An arginine-grafted bioreducible poly(disulfide amine) (“ABP”) as a reagent for efficient and nontoxic gene delivery is described. ABP forms positively charged nano-particles of less than 200 nm with plasmid DNA. ABP is biodegraded under reducing conditions, such as the cytoplasm. ABP exhibits much higher transfection efficiency than polyethyleneimine in mammalian cells and exhibits no cytotoxicity.

Disclosed herein is a protection circuit module (PCM) including a protection circuit for controlling overcharge, overdischarge, and overcurrent of a battery. The protection circuit module includes a pair of connecting members, which are mounted to a rectangular lower end of the PCM and electrically connected to a protection circuit, and a pair of coupling members coupled to the corresponding connecting members while plate-shaped electrode terminals of a battery cell are interposed between the connecting members and the coupling members, and a battery pack including the protection circuit module, which is electrically connected to a battery cell. According to the present invention, a welding or soldering process, which requires a large amount of time and a high degree of technical skill to manufacture a battery pack, is not necessary, the coupling force between the battery cell and the PCM is increased, and the inner space of the battery pack is maximally utilized.

Disclosed herein is a shared Local Area Network (LAN) emulation method and apparatus. The method includes the following four steps. At the first step, a Logical Link Identifier (LLID) management table is set up to assign unique LLIDs to a plurality of Optical Network Units (ONUs) and manage the assigned LLIDs so as to identify the plurality of ONUs connected to a single Optical Line Terminal (OLT). Thereafter, a MAC address table is set up for the LLIDs to learn MAC addresses of the ONUs. Thereafter, the unique LLIDs are assigned to ONUs when the ONUs request registration from the OLT. Finally, data frames, which are received by a Shared LAN Emulation (SLE) layer of the OLT, are bridged using the LLIDs, VIDs of Virtual LANs to which the ONUs belong and destination MAC addresses of the data frames so as to provide a single matched port between a Logical Link Control (LLC) layer and a MAC layer of the OLT.
