Abstract: A controller may measure resonance current of a working coil, measure driving voltage of a switching element included in an inverter circuit that supplies current to the working coil, and generates a phase margin pulse based on the resonance current and the driving voltage. The controller may compare the phase margin pulse with a switching signal and determine a driving state of the induction heating apparatus, and control driving of the working coil based on the driving state of the induction heating apparatus. Additionally, when it is determined that a driving frequency of the working coil is included in a capacitive area, the induction heating apparatus stops from operating, or a driving frequency of the working coil is set again.

Abstract: Disclosed is a method for preventing or treating thrombosis, the method comprising administering a composition containing a hemp (Cannabis sativa L.) leaf or flower extract as an active ingredient. The hemp (Cannabis sativa L.) leaf or flower extract inhibits thrombus formation-related enzymes and coagulation factors and exhibits potent antithrombotic activity through inhibitory activity against platelet aggregation which triggers blood clotting, but with no lytic activity on human erythrocytes. In addition to being stable to heat, the extract does not lose the inhibitory activity against coagulation factors and thrombus formation-related enzymes even in the acidic condition of pH 2 and the plasma environment. Therefore, the extract is expected to find applications in preventing and treating thrombosis such as ischemic stroke and hemorrhagic stroke through blood circulation improvement.
