Abstract: A wafer manufacturing method, an epitaxial wafer manufacturing method, and a wafer and epitaxial wafer manufactured thereby, are provided. The wafer manufacturing method enables the manufacture of a wafer with a low density of micropipe defects and minimum numbers of particles and scratches. The epitaxial wafer manufacturing method enables the manufacture of an epitaxial wafer that has low densities of defects such as downfall, triangular, and carrot defects, exhibits excellent device characteristics, and improves the yield of devices.

Abstract: An air conditioning device for a vehicle includes: a housing having an inside divided into an inflow space, a heat exchange space, and an outflow space, which are straightly arranged, and having a plurality of discharge ports, which communicates with an interior, at the inflow space; a blowing unit disposed at the inflow space of the housing and configured to blow air; a heat exchange unit disposed at the heat exchange space of the housing and configured to adjust a temperature of conditioned air by exchanging heat with air; and an opening-closing door disposed at the outflow space of the housing and configured to open and close the plurality of discharge ports such that conditioned air at an adjusted temperature selectively flows to the plurality of discharge ports. The air conditioning device adjusts the temperature of conditioned air for respective modes and reduces a flow resistance of air.

Abstract: A self-healing alloy contains 5 to 11% by weight of molybdenum (Mo), iron (Fe) as a remainder, and unavoidable impurities. A method for manufacturing the self-healing alloy includes heat treating the alloy or preparing an alloy raw material powder and sintering, homogenizing, and cooling the alloy raw material powder.

Abstract: A system and method for monitoring security around a vehicle are provided. The method includes searching, by a controller, for a mobile device in the vicinity of the vehicle and determining whether a detected mobile device is an identified mobile device previously known to the vehicle. When the detected mobile device is the identified mobile device, the controller is configured to continuously search for another mobile device. When the detected mobile device is an unknown mobile device, the controller is configured to transmit information regarding the detected mobile device to a driver of the vehicle when the time or the frequency of which the detected mobile device is searched in the vicinity of the vehicle is greater than a pre-set time or frequency.

Abstract: The present disclosure provides a system and a method capable of properly supporting a driver by monitoring driver information and vehicle data in real time by linking with a wearable smart device and providing the driver information to a medical center, an emergency center, or an emergency vehicle through a mobile communication network upon an occurrence of an emergency situation of the driver.

Abstract: A method for determining a position of a wireless terminal belonging to a passenger positioned in a vehicle; providing interworking devices among devices provided in the vehicle interworking with the wireless terminal based on the position of the wireless terminal; bi-directionally interworking a device selected by the passenger among the provided interworking devices and the wireless terminal with each other through short range communication; and controlling the selected device through a display of the wireless terminal.
