Abstract: A coupled torsion beam axle for vehicles may include a torsion beam disposed in a vehicle width direction and trailing arms disposed at both ends of the torsion beam in a length direction of a vehicle body, wherein the torsion beam has an opened cross section formed in a reverse “U” shape by press-forming one sheet member machined so that lengths of right and left sides are different from each other on the basis of a center, and cross section widths which are different from each other along vehicle width directions of both sides on the basis of the center between the trailing arms of both sides, and front and rear surfaces formed in a wave shape along the vehicle width directions of both sides on the basis of the center.

Abstract: A biguanide derivative compound with N1-N5 substitution, which is represented by Formula 1, or a pharmaceutically acceptable salt thereof a method of preparing the same, and a pharmaceutical composition containing the same as an active ingredient are provided. The biguanide derivative may exhibit excellent effect on activation of AMPK? and inhibition of cancer cell proliferation in a low dose, compared to conventional drugs, and thus, may be useful to treat diabetes mellitus, obesity, hyperlipidemia, hypercholesterolemia, fatty liver, coronary artery disease, osteoporosis, polycystic ovarian syndrome, metabolic syndrome, cancer, etc.

Abstract: The present invention relates to a method for easily preparing (2RS)-amino-(3S)-hydroxy-butyric acid, which is a chiral amino acid, in a high yield and a high purity using a chemical synthesis and enzymatic reduction reaction; an intermediate therefor; and a method for preparing the intermediate.

Abstract: A localization system includes terminals and a server. The terminal includes an antenna unit to receive a wireless signals, a distance determining unit to determine a distance relative to other terminals using intensity information of the wireless signals, a direction detection unit to obtain an orientation of the terminal, and a control unit to control the terminal. The server includes a calculating unit to calculate a distance between the terminals based on intensity information, and a memory unit to store the distance information. The control unit may calculate a relative location of other terminals using a triangulation method based on the distance information between the terminals. The control unit may determine a location and orientation of another terminal based on a forward direction or orientation of the terminal obtained by the direction detecting unit of the terminal and the relative location of other terminals.

Abstract: The present invention provides metformin butyric acid salt, a method of preparing the same, and pharmaceutical compositions and combinations containing the same. The metformin butyric acid salt according to the present invention has an excellent pharmacological effect as compared with metformin hydrochloride and is capable of achieving a therapeutic purpose by administering an amount less than metformin hydrochloride. Furthermore, the metformin butyric acid salt has excellent physicochemical properties, such as solubility, stability, hygroscopicity and adsorption preventing property, in processibility of formulations and thereby is capable of being usefully utilized as a pharmaceutically acceptable salt of the metformin.

Abstract: A preamble transmission method for a wireless communication system is provided for improving the probability of successful transmission and reducing unnecessary retransmission power consumption. The preamble transmission method of the present invention calculates an initial transmission power; transmits a preamble with the initial transmission power through a random access channel; if an acknowledgement is received in response to the preamble, starts transmission of data; and if no acknowledgement is received in response to the preamble—calculates a retransmission power, and retransmits the preamble with the retransmission power.

Abstract: A remote control method of a home network and system thereof are disclosed to remotely control devices connected to a home network system. A control point of a home network is set at a home agent in the home network system and at a remote terminal respectively, and then the control point set at the home agent and the control point set at the remote terminal are connected through a specific channel, thereby controlling the device(s) connected to the home network system.

Abstract: A remote control system of a home network includes a local home network to which plural devices are connected; a remote terminal for controlling the local home network from a remote place; and a remote access server having a function of a local control point and transferring and receiving request/response to and from the remote terminal. States of equipments connected to the home network can be monitored and controlled by using various terminals.

Abstract: Synchronization method of an UPnP (Universal Plug and Play)-based home network is disclosed to automatically transfer information of a CP (Control Point) to a different CP. By switching a role of the CP or generating a virtual UPnP device through the CP, information among plural CPs according to user's roaming can be automatically transferred or exchanged, guaranteeing a continuity of an operation. Thus, time for constructing a system can be reduced and user's convenience is maximized.

Abstract: A method and apparatus of providing a public network service when a call management device is in a down state in a private wireless network is disclosed. The present invention provides the public network service when a call management device is in a down state in wire and wireless composite communication system serving through wire terminal and a wireless terminal by connecting the wireless network to an extended network linked to the public network. The method of providing a public network service having the steps of periodically checking, at the base station controller, a state of the call management device, and performing the wireless public network service when the call management device is in a down state.
