Abstract: PURPOSE: A virtual machine-using file system management device and a method thereof easily and timely analyze an error taking place in a file system due to a certain activity of the system or an object by setting a certain file in the system or a certain object as a monitoring point. CONSTITUTION: A virtual machine (VM) (120) includes an operating system with a kernel module (122) for analyzing a file system (123). A control unit (110) controls the VM, sets a certain point of the kernel chosen by a user as a monitoring point, notifies a display unit about the setting of the monitoring point, and requests the VM to generate a snap shot for the monitoring point. Upon the request by the control unit, the VM generates a snap shot for the monitoring point. The control unit sets the monitoring points only on those files corresponding to a certain path of the file system, certain i-nodes, or certain blocks as a debugging target.

Abstract: PURPOSE: Doppler radar based target displacement detection method and apparatus are provided to classify the movement of background and the movement of a real target. CONSTITUTION: A Doppler signal of a real target is received(S110). The phase of the Doppler signal is measured(S120). The real movement amount of the real target is measured based on the phase(S130).
