Abstract: In a method for coating on a surface of a medical PEEK material with titanium to have a microporous structure, titanium is coated on a surface of polyether ether ketone (PEEK) via magnetron sputtering. The surface of the titanium coated on the surface of PEEK is polished via an electromagnetic polishing apparatus. A thin-film with titanium dioxide (TiO2) having a microporous structure is formed on the polished surface of the titanium via an anodic oxidation treatment.

Abstract: The present invention relates to a patient-specific breast implant. More particularly, the present invention relates to a patient-specific breast implant which, when a breast-conserving surgery (BCS, also called lumpectomy or partial mastectomy) is performed to remove breast cancer while leaving as much normal breast tissue as possible, prevents deformation of breast that may occur due to the depression of breast skin or adhesions of remaining breast tissues after the BCS, shortens surgery time, and facilitates securing breast symmetry, thereby ultimately dramatically increasing the success rate of surgery and maximizing patient satisfaction.

Abstract: A display device includes a display panel and a panel driver. In a case where input image data represents a moving image with respect to a first partial region and represents a still image with respect to a second partial region, the panel driver performs a normal frequency driving operation on the first partial region, and performs a low frequency driving operation on the second partial region. In a standby mode, after the normal frequency driving operation and the low frequency driving operation are performed on the first partial region and the second partial region, respectively, the panel driver sets a portion of the second partial region adjacent to the first partial region as an adjacent region, performs the low frequency driving operation on the first partial region and the second partial region except for the adjacent region, and performs a variable frequency driving operation on the adjacent region.
