UFMC(Universal Filtered Multi Carrier)는 OFDM(Orthogonal Frequency Division Modulation)보다 비동기적인 상황과 ICI(Inter Carrier Interference)에 강한 장점으로 5G 무선통신 시스템의 후보로 주목 받고 있다. UFMC 시스템에서는 부밴드 마다 필터링을 하기 때문에 필터의 성능이 매우 중요하다. 기존 UFMC 시스템의 필터는 대역외 방사가 작다는 장점으로 필터를 사용해 왔다. 그러나 이 필터는 부밴드 내의 왜곡이 있고 스커트 특성이 좋지 않다. 따라서 부밴드 내의 왜곡을 줄일 수 있으며 스커트 특성이 뛰어난 새로운 형태의 UFMC 필터에 대한 연구가 필요하다. 본 논문은 UFMC 시스템에서 필터의 주파수 응답 형태가 미치는 영향을 분석하고 기존 시스템에서 사용되어 왔던 Dolph-ChebyShev 필터를 대체할 필터로 Wavelet 기반의 필터를 제시한다. 모의실험을 통해 wavelet 필터가 기존의 필터 보다 다중 경로 페이딩 채널에서 더 나은 BER(Bit Error Rate)성능을 보임을 확인 하였다.

The purpose of this study is to evaluate the differences of visual effects by variations in the number of pleats and the length of the pleats skirt. The stimuli are 18 samples: 6 variations of the number of pleats and 3 variations of the length of skirt. The data has been obtained from 54 fashion design majors. The data has been analyzed by Factor Analysis, Anova, Scheffe's Test and the MCA method. The results of the study are as follows: The visual effects by the number of pleats and the length of skirt are composed of 3 factors : vertical of lower body, curves of lower body and shape abdomen. In these factors, vertical factor is estimated by the most important factor. The visual effect is positive when the number of pleats is added and the length of skirt is getting shorter. The short length of skirt and more pleats make legs and calves looked long and slim. The interaction effects between the number of pleats and the length of skirt do not appear. In the vertical of low body factor, the length of skirt is more effective than the number of pleats, and in the curve of low body factor, the number of pleats has more effects than the length of the skirt. In the shape of abdomen, the number of pleats and length of skirt have similar influences.

Interests in 3D virtual clothing technology and its application in online shopping malls are increasing with the advent of the Fourth Industrial Revolution. Most studies on 3D virtual clothing, however, are focused on observing drapes or ease of virtual clothing depending on fabric properties of representative clothing items. Therefore, the purpose of this study is: first, to determine if current input of typical material characteristics in 3D CLO are sufficient to formulate virtual skirts with different front and back silhouettes; second, to determine if subjective appearance evaluation matched physical shape characteristics of those skirts. In this study, appearances of typical cotton, wool, silk, rayon, and polyester skirts with different front and back pattern were compared between actual and virtual clothing depending on fabric materials. Subjective appearance evaluation was conducted by 7 experts regarding similarity between actual and virtual clothing with a 5-point scale. For objective evaluation of the both types of skirt shape, degree of roundness at the cross section, displacement of side seam, position of back waistline, and the number of folds at the skirt back were observed. In the case of cotton and wool, not the subjective appearance evaluation as well as shape characteristics of virtual skirts were well matched to the actual shape of skirts with a few material inputs. However, current material inputs for silk, rayon and polyester were insufficient to cover material differences in formation of virtual skirts with different front and back silhouettes.

The study aims to suggest new skirt designs through a modernistic application of the silhouette of Hanbok skirts. It also aims to promote the aesthetic beauty and excellence of Hanbok to the world by using Hanbok skirts that best express the beauty of Korea as motifs, and to promote a pride in Korean culture through a reinterpretation of Hanbok skirts. The study was focused on examining Hanbok skirts from the Three Kingdoms era to the Joseon Dynasty, and the skirts in each era were compared to western silhouettes to suggest design centering on the characteristics of each silhouette. As for the theoretical background, shapes were classified according to waist-grip, the width and length of a skirt, wrinkles and ornamental lines, before being compared to skirt silhouettes of western costume. As a result, it was found that Hanbok skirt silhouettes in the Three Kingdoms era were similar to the A-Line silhouette of western costume, the Empire silhouette of unified Silla, the H-Line silhouette of the Goryeo Dynasty, the Bell-Line silhouette of the Joseon Dynasty and the Bustle Style applied to ceremonial costume in the early Joseon Dynasty. The researcher suggested five skirt designs by applying the above-mentioned five silhouettes, confirming the research premise that Hanbok skirt silhouettes are as diversified as those found in western costume. Designs were suggested for each silhouette, and are expected to lead to the development of designs befitting future trends and concepts through detailed research and development on Hanbok skirt silhouettes.
