The purpose of this research was to compare the preference of tone on tone coloration of traditional Korean dress by Korean and American women college students. The respondents were asked to evaluate 48 stimuli of the traditional Korean skirt and jacket with different tone of color. It could be supposed that the different evaluation were caused by their different cultural backgrounds. The results of research can be summarized as follows. As to the red colors, Korean students preferred vivid and light tone coloration, and disliked dull and dark tone coloration, the same tone coloration. but American students preferred usually the same tone coloration and preferred coloration of 4 tone skirts and vivid jacket, dull and dark tone coloration. As to the yellow colors, Korean students preferred dull and dark tone coloration and disliked the same tone coloration. American students preferred vivid and light tone coloration and disliked dull tone coloration as dull jacket and skirt. As to the green colors, Korean students preferred dull and dark tone coloration and disliked the same tone coloration. American students preferred dull and dark tone coloration and preferred the same tone coloration.

The purpose of this research are to identify the nature of artistic beauty of Kokuryeo dresses and to apply the artistic beauty, formative uniqueness, and esthetic value of Kokuryeo in the modern Korean dress design for creation of new designs. Significance of this research lies in the fact that beauty of traditional dresses possesses highly valuable importance for application to modern fashion design processes. Kokuryeo dresses basically comprised of Yu, Sang, Go and Po, and contains within abstract beauty along with emphasis on geometric elements like dots, lines, and surfaces. Red, Black, Violet, Verdant and scarlet colors were moderately used against the mainly white canvas, and different colors were often used for the top and the bottom. Silk, Hemp cloth and Wool were used for different social levels or ranks, and from the wide variety of colors and patterns of the dresses, such as Round-patterns, Cloud-patterns and Vine-patterns, worn by the people illustrated on the wall paintings, it appears that various materials were used. Vertical hems, Yu (shirts), Sang (skirts), noblemen's dresses, kings' dresses, etc. from Kokuryeo tomb wall paintings were applied, and various dying methods, natural materials and sewing methods were used to recreate the unique features of Kokuryeo dresses in modern designs in an attempt to recreate the esthetic value of Kokuryeo dresses.

Many mobile communication systems require bandpass filter with sharp skirt characteristics and consequently a filter was formed by more order. It needs to improve flatness in passband. In this paper, amplitude equalizer was used to improve the flatness of passband. We modified Chebyshev prototype filter by use of network synthesis and computed the prototype elements for Shaping filter. We designed and realized a 13-order combline bandpass filter and 4-order amplitude equalizer with coaxial dielectric resonators at WiBro band. The measured results show $\pm$0.82 dB amplitude difference in passband, 6 dB improved flatness.

In this study, using the general expressions predicting the pressure under a blade and the volume of coating fluid passing through the blade edge, it is predicted the change of the coating wet film thickness related with various parameters determining the characteristics of this blade coating process. Using the results of this research, it can be found the optimized coating wet film thickness taking into account the parameters related with various coating process on various metal surfaces will be able to be predicted.

본 논문에서는 개방 스터브(open stub)와 전송선로가 커플된(coupled) 구조를 Chebyshev prototype을 이용하여 저역통과 여파기를 설계하였다. 같은 길이의 스터브를 연속적으로 배열함으로써 깊은 저지대역을 갖고, 커플링에 의해 우수한 스컷 (skirt) 특성을 갖는 여파기를 설계할 수 있었다. 또한, 감쇄극이 다른 스터브를 추가로 연결하여 저지대역을 확장하였다.

In this letter, a novel compact duplexer which consists of Tx and Rx Filter using microstrip line ${\lambda}/4$ resonators with a pair of tap-connected open-ended stepped impedance stubs is designed. The tapped open stubs not only work as K-inverters but also introduce attenuation poles, attenuation poles are located at upper and lower side of the passband by adjusting the open stub length and width. The result of measurement duplexer has been yielded better isolation and sharper skirt behavior than that with a conventional bandpass filter and similar to those of simulation results.

In this paper, we propose a microstrip bandpass filter using stepped-impedance coupled-line hairpin resonators. The stepped-impedance coupled-line hairpin resonator has extended harmonic suppression in comparison with a conventional hairpin resonator due to transmission zero and the movement of harmonic frequencies resulting from the stepped-impedance characteristic. A high-pass type impedance/admittance inverter is employed in order to improve the lower frequency skirt characteristics of the passband. A 4-pole bandpass filter is designed and fabricated at 1.8 GHz. The measured results show the excellent attenuation performance at the stopband which is greater than 30 dB up to 10 GHz.

The purpose of this research was to compare the harmony of tone on tone coloration according to transformation of color area-ratio in traditional Korean dress. The respondents were asked to evaluate 36 stimuli of the traditional Korean skirt and jacket with different color tone. The subjects were 83 female undergraduate students. The results are as follows. For red colors, combinations of vivid/dull, vivid/dark, and light/dark made a difference in the harmony of coloration according to the transformation of color area-ratio. For yellow colors, combinations of vivid/dark, light/dull, and light/dark made a difference in the harmony of coloration according to the transformation of color area-ratio. For green colors, combinations of vivid/dull, vivid/dark, light/dull, and light/dark made a difference in the harmony of coloration according to the transformation of color area-ratio.

In order to enhance satellite communication system performance, filters are required with the characteristics of sharp skirt, low insertion loss, and high power handling capability. But the performance of microwave passive filters is significantly declined by the conduction losses, especially in case of planar structures using film conductors. By using high temperature superconducting(HTS) film material as the conductor, higher performance could be expected. We have designed and developed narrow bandpass filters using haripin-type superconducting microstrip line for satellite communication. High quality superconducting YBCO thin films have been grown on MgO substrates by pulsed laser deposition(PLD) The deposited YBCO films were patterned by conventional wet-etching process. The transition temperatures of these films had shown 86 - 89 K. The film thicknesses were about 500 nm. Experimental results are presented for the insertion loss and return loss of the filter at 60 K.
