Provided is a device and a method for adjusting a loop filter gain in an automatic frequency controller, which can allow the automatic frequency controller to operate while maintaining an optimal performance. The device includes a velocity estimator for estimating a change in velocity in accordance with a movement of a terminal; a loop filter gain controller for controlling a loop filter gain in accordance with a change in velocity received from the velocity estimator; and a loop filter gain unit for multiplying a loop filter gain received from the loop filter gain controller and a frequency error for output. Further, there is provided a method for adjusting a loop filter gain in an automatic frequency controller, having the steps of: estimating a change in velocity in accordance with a movement of a terminal; adjusting a loop filter gain in accordance with the estimated change in velocity; and multiplying the adjusted loop filter value and a frequency error for output.

The present invention relates to a method for preparation of the supersaturated calcium and phosphate ions solution and a method for preparation of the thin film of calcium phosphate crystal on solid surface by using the said solution. Particularly, the lowered temperature and/or the use of suitable buffer system inhibit the nucleation of calcium phosphate in aqueous solution, and thereby highly supersaturated calcium and phosphate ions solution can be prepared. And the thin film of calcium phosphate crystal on solid surface can be prepared with rapidity and good quality of high reactivity and low crystallinity by using the said solution. Also the thin film of calcium phosphate crystal prepared according to the present invention has biocompatibility and can be applied as biomaterials.
