Abstract: Disclosed are taxifolin derivative with superior antioxidant effect, a method of synthesizing the same and a cosmetic composition containing the same. In accordance with the method, taxifolin derivatives having higher antioxidant activity than taxifolin can be synthesized using lipoic acid. As such, a novel taxifolin derivative synthesized according to the present invention can exhibit anti-aging effects when used for cosmetics and the like.

Abstract: A method and apparatus for performing an image forming job by maintaining a cover, which covers a scan area and has adjustable transparency, in a transparent state until a job for acquiring image data of a scan object starts in an image forming apparatus. If the job for acquiring the image data of the scan object positioned in the scan area starts, the image forming apparatus converts the cover into an opaque state and acquires the image data of the scan object. If the job for acquiring the image data of the scan object is ended, the image forming apparatus reconverts the cover into a transparent state. Therefore, efficiency of a job for acquiring image data of a scan object is improved.
