摘要： The present invention relates to carbon nanotube fibers reinforced with a carbon precursor and a method for manufacturing the same. The carbon nanotube fibers reinforced with a carbon precursor according to the present invention are carbonized by the empty space inside the carbon nanotube fibers being filled with a carbon precursor, and therefore, are highly effective in that the mechanical and thermal properties are improved due to effective stress transfer and contact resistance decrease, and these properties are maintained intact even at high temperatures.

摘要： A mobile device and a method of operating a mobile device are disclosed. The mobile device includes a main processor executing a normal code of a mobile application program, a co-processor executing a core code of the mobile application program, and a co-processor driver enabling the main processor and the co-processor to communicate with each other. The normal code includes commands executable by the main processor, and the core code includes commands executable by the co-processor. Since the core code is separated from the mobile application program on a level lower than an operating system level when the mobile application program is installed on the mobile device and the core code is stored in a core code storage to which the main processor is not allowed to access directly, the core code is not exposed to an attacker, such that resistance to a reverse engineering attack is increased.
