The hat on the back of the upper jacket in Scythian, in of northern region surrounding the Black Sea, is described as a typical woolen hood, but until now has been overlooked in Korean costume studies. The purpose of this study is to analyze the hat on the upper jacket in Scythians and to recognize the meaning of the hat. A further purpose is to complete the basic framework of research concerning the Scythian costume by adding the part that was overlooked previously As for the research method, we collected literature, previous research results, the exhibition catalog, and the related artifacts for analysis. The literature was collected at the German Archaeological Research Institute. The analysis of artifacts was based on data collected by the researchers at the Heremitage Museum in Russia and data was taken by the staff of the Heremitage Museum. The conclusions of this study are as follows: Among the artifacts in the northern region of the Black Sea, it was perviously believed that Scythians status was signified by the wearing of hat-tops. Regardless of age, warriors and knights all wore upper jackets with hats, so it appears that the people who are active wore upper jackets with hats. On the other hand, it was assumed that the royal family, who wore ornamented, colorful, and decorative hats were not observed to have worn upper jackets with hats, and therefore did not require a hat. Therefore, it is considered that the hat in the Scythian society was a costume element emphasizing practicality, not necessarily a class symbol.

다지털 카메라의 mosaicked image는 Bayer CFA 등의 센서를 통해 획득되며 full resolution의 컬러 영상을 얻기 위해서는 demosaicking이라는 과정이 요구된다. 그러나 시그널이 센서를 통과할 때 noise가 더해지게 되기 때문에 이를 제거하기 위한 denoising process는 demosaicking 과정 전단에 반드시 고려되어야 하는 것이다. 본 논문에서는 demosaicking과 denoising을 분석하고 효율적으로 noise를 제거하는 방식을 제안한다. 제안된 알고리듬은 noiseless CFA에서 얻어지는 필터를 수정함으로서 얻어지며, 낮은 연산량과 함께 만족할만한 성능을 보여준다. CPSNR, SCIELAB, FSIM로 대표되는 화질 측정 방식들은 제안하는 알고리듬이 다양한 레벨의 noise를 효율적으로 제거한다는 것을 보여준다.
