Abstract: A combined power generation system includes a gas turbine including a compressor configured to compress air, a combustor configured to mix the compressed air from the compressor and fuel and combust a mixture of the compressed air and fuel, and a turbine section in which rotational power is obtained by combustion gases generated by the combustor. The system also includes a heat recovery steam generator (HRSG) in which steam is generated by heat of exhaust gases from the gas turbine, and a steam turbine driven by the steam generated by the HRSG, wherein the HRSG includes a plurality of heat exchangers provided to cool the compressed air by heat exchange between the compressed air and the exhaust gases.

Abstract: Access of a home network terminal to a work server in a telecommuting environment is effectively managed to maintain security of the terminal. According to one embodiment of the present invention, a method for controlling access to a remote system in a home network environment includes: an access request reception step of receiving a request signal according to a network protocol when an access request for a remote server, which is an access target, is performed by a terminal on a home network; a security environment inspection step of checking the security environment of the terminal through a host sensor for each protocol that has received the request signal through the access request reception step; and an access permission step of managing access to the remote server according to the security environment checked according to a result of performing the security environment inspection step.

Abstract: A parking assist system with improved avoidance steering control and a method thereof are provided. The parking assist system includes a sensor fusion calculation module that fuses sensing data of an ultrasonic sensor and image data of an SVM camera to calculate position information of an object with respect to a current location of a vehicle and a parking assist module that avoids the object based on the position information and performs steering control of the vehicle for autonomous parking. The parking assist system accurately detects the object on a position departing from a field of view (FOV) of the ultrasonic sensor and performs avoidance steering robust to a surrounding object upon autonomous parking.
