A Chebyshev filter is well known for having a sharp skirt characteristic and equi-ripple. On the other hand, a Butterworth filter has a smooth skirt characteristic and maximally flat ripple. This paper analyzes the skirt characteristics of the filters with the cascade connection. The paper deals with the Chebyshev BPF, Cascading Chebyshev BPF, Butterworth BPF, Cascading Butterworth*Chebyshev BPF. First of all, the paper designs the prototype analog LPF in order to analyze skirt characteristics of the BPFs. Then the paper does the frequency transformation into the BPFs and tests the BPFs with cascading them. As a result, the skirt characteristics of the Chebyshev BPF was the sharpest and those of the Cascading Chebyshev BPF, Butterworth BPF, Cascading Butterworth*Chebyshev BPF was superior in order. The validity of the paper was confirmed through minute measurements of test results.

The purpose of this study is to analyze the formative characteristics of accordion pleats shown in 10/11 S/S London, Paris, New York collection and evaluate the differences of visual image by variations in the width of pleats and the length of the accordion pleats skirt. The stimuli are 21 samples: 7 variations of the width of pleats and 3 variations of the length of skirt. The data has been obtained from 43 fashion design majors. The data has been analyzed by Factor Analysis, Anova, Scheffe's Test. The results of the study are as follows: Accordion pleats was first introduced by Marriano Fortuny. He published delphos dress by creating silk pleats manufacturing technique and it was recognized as the best pleats work. Since then, pleats with synthetic fiber characteristics were used by many fashion designers. Accordion pleats were used in various items including one-peice, skirt and pants in collection of 2010 and 2011. The design of accordion pleats skirt used different width of pleats, length of the skirt and materials. The visual image by the width of pleats and the length of skirt are composed of 3 factors : dearness, attractiveness and elegance. In these factors, dearness factor is estimated by the most important factor. The accordion p1eats skirt is most attractive and dear when the width of pleats is the shortest, 1/8", and the width of 4/8" and 5/8" follows. The accordion pleats skirt is most attractive and dear when the length of skirt is similar to that of mini-skirt, and the skirt was estimated to be elegant as the skirt gets longer. When the length of skirt is in between, the skirts were estimated to be ambiguous in all visual images. The interaction effect of visual image according to the changes in width of pleats and skirt length of accordion pleats skirt was seemed to have significant differences by factors, and the main effect had great differences in all factors.

The Purpose of this study is to investigated characteristics of many pleated skirt of Miao women's Guizhou province in China. The method of this study is referd to sundry recordes and demonstrated traditional clothing of several region in Guizhou province. The most important characteristic of the costume of the Miao is the many pleated skirt, worn by most but not all groups. Pleats are pulled into place with a sharp pointed instrument and sprinkled constantly with starch. The length of the pleated skirt depends on the group. The long skirts reach to the ankle, the medium-sized to the shank and the short ones not below the knee. The design of the pleated skirt is simple but most pleated skirt ornamented with fine, cross-stiched or batic designs of geometrical figures. The figures decorated on the pleated skirt has been handed down with little change from generation to generation and has become an important mark of Miao women's each area. Seeing the many pleated skirt of Miaos investigated in these several respects by the standard of contemporary beauty, it is thought that it has the infinite possibility of being used in contemporary fashion design on account of the characteristics of almost perfect costume.

Skirts hold an important position in dress culture among various dress forms, being worn by more than half of mu. In this study, Chima is defined as garment for lower part of the body without crotch sewing, contrasting with trousers. The authors classify and compare the formation of the skirts of minority races in Yunnan area, based on Korean Chima, understanding the forms of skirts and examining the composition, color, pattern and material. For the study, the authors investigated 57 pieces of skirts among 341 pieces of minority races dresses from Yunn Nationality Museum collection exhibited at Korea Folk Village in May 2003, and referred to customs materials and photos in various literatures. Skirts in Yunnan area are divided into 6 areas, that is, seamless one-piece skirt area, wrapskirt area and mixed type skirt area. Skirt formation factors from the effect of environment such as climate, lifestyle and means of production were studied, and characteristics, differences and similarities were reviewed. Figure of skirts are studied by compostion, color, material, and technique. By composition, they can be classified based on the similarity to Hanbok (traditional Korean dress). By color, worshipped color and preferred color vary by races and by area. Materials vary in kinds and thickness by area with various climate. By technique, national characteristic patterns are inherited through national traditional dyeing and embroidery. It is not easy to conclude based on single item of skirt, but we suggest that national dresses have been settled through the mutual supplements between the effect of social and cultural exchange such as historical inheritance, geological environment, religion and production activity and the various forms of skirts from changes in shape, color, material and wearing form of dresses.

The purpose of this study is to help user understand the basic principles and interfaces of each program, and to provide a base material for the development of more efficient apparel CAD systems to compensate for each program's shortcomings by comparing the function of three apparel CAD systems: Yuka CAD, Opti-tex, and Style CAD. For this purpose, the skirt waistband and sleeve armhole line creation process were selected based on these two criteria. 1) There is a big difference between principle and method between CAD systems. 2) When CAD system is used rather than paper drawing process, the process is shortened and convenience is high. In this study, pros and cons and supplement point of each CAD system are suggested by comparing the functions of the CAD system performing the selected drafting process by four criteria: icon, key, method, and characteristic point. As a result of the study, it was confirmed that the three CAD systems differ in the basic principle and interface environment. As a result of analyzing the skirt waistband method function, it was confirmed that the band line is formed directly on the outline of the skirt and the band dart recognition function is the most efficient function and as a result of the analyzing the sleeve armhole line method function, it was confirmed that the curve generation function using the shape of the actual curve measure and the length adjustment function through the automation of the dimension calculation is the most efficient function.

In terms of junior high school girls' growth patterns during early adolescence, unlike childhood when relatively balanced growth patterns are found and high school years in which the normal adult body type is almost reached, junior high school girls display imbalanced and rapid growth. In fact, diverse size changes by body part occur with a significant difference among individuals. Therefore, it has been difficult for junior high school students to select their exact size when buying a school uniform. This study attempted to develop winter blouse and skirt patterns reflecting the latest comfortable and active school uniform trends, using middle school girl avatars of various body shapes. Skirt and blouse pattern-drawing methods and margins differed. Based on such results, research prototypes were prepared. Then, virtual wear prospective drawings, clothing pressure, and appearance were assessed by body shape. Skirts were assessed with 22 factors while blouses were analyzed with 25 factors. Then, correlations between skirts and blouses were analyzed. According to the analysis, the reason why the dart & pleats position and margin were rated low was confirmed. In a virtual wear assessment on skirt patterns by body shape, a significant difference was found in all categories except for position of the hip circumference, margin of the hips, width of the skirt, and appropriateness of waist line position. The virtual wear assessment on the blouse patterns by body shape also revealed a significant difference in all categories but fit and shape pf the back part. In blouses, a significant difference was observed around shoulders and waist in type 1 and around the belly in type 2. On the contrary, for skirts, a significant difference was found around the hips and waists in type 1 and type 2. Therefore, these factors should be considered in making blouses and skirts. The above results suggested that skirt and blouse patterns should vary by body shape. It is anticipated that there should be further studies comparing brand-name school uniforms for high school girls and school uniforms by body shape.
