Abstract: The present invention provides a device for conducting dynamic analysis of embedded software of a vehicle. More particularly, it relates to a device for dynamically analyzing embedded software of the vehicle to detect real time errors of embedded software based on the analysis. More specifically, a data communication unit communicates data in real time with an electronic unit of the vehicle; and a control unit that monitors the condition of one or more hardware components which are used by embedded software of an electric field based on the data received through the data communication unit, and thereby outputs the monitored result accordingly.

Abstract: The present invention relates to a method for purifying hyaluronic acid using calcium salt and phosphate salt, or calcium phosphate salt, specifically to a method for purifying hyaluronic acid characterized by effectively removing lipids, nucleic acids and proteins from an extract or a culture solution which contains hyaluronic acid by treating with calcium salt and phosphate salt, or calcium phosphate salt. According to the method of the present invention, it is possible to purify hyaluronic acid more effectively, by avoiding a use of toxic organic materials as well as reducing additional processes.
