This paper proposes a geometrical method for generating and draping the skirt 3D models. The method constructs a 3D basic skirt model using a truncated elliptical cone and generates the various skirt 3D models by controlling the elliptical cone. The B-Spline approximates the 3D drapes which change variously according to the angles and the textiles of the skirts. The mapping sources consist of the textile textures and the skirt 2D model. The 2D models are obtained by mapping the 3D skirt models to the 2D plane. The mapping sources allow us to map the textiles to the 3D skirts. We make the real skirts for the 6 kinds of angles and textiles. and investigate the data of their drape appearances. The investigated data are applied to the virtual skirts. Appearances of the virtual skirts are similar to those of the real.

This study was performed to develop the flare skirt pattern in CAD system by each of the textile's test. 1 made 28 flare skirts(360$^{\circ}$, length of 60 cm, straight gram at front ST side seam, 28 kind of textiles) and found the changes of skirt length. And I measured thickness, weight, density, drapability and bending in these textiles. Therefore, It analyzed these data and found it regression.

The purpose of this study is to evaluate the differences of visual effects 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 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 2 factors: verticality and thickness of lower body, shape of abdomen. In these factors, verticality and thickness of lower body factor is estimated by the most important factor. The accordion pleats skirt makes the lower body look longer when the width of the pleats is wider, and helps the calf and leg look thinner. Also, the waist looks more slender and thin. As the skirt gets longer, one looks taller, and legs look longer and thinner. The shape of abdomen is no difference according to the width of pleats. As the skirt gets longer, the waist looks more slender and thinner. The interaction of visual effect according to the changes in width of pleats and skirt length of accordion pleats skirt is not shown, and the skirt length has more effect than the width of pleats does in verticality and width of lower body factor. The width of pleats has more effect than the skirt length does in shape of abdomen factor.

In this study, visual images were analyzed with the representative seven kinds of selected skirts, by the differences of shape and length which are affecting to the images of skirts. In addition, the purpose of the study is to present the basic data for the skirt design and patterns those are appropriate to the preferred images of 20-30s. The results of this study are as follows. First, analyzed by the visual evaluation about the composing factors are as follows. Factor 1 is a Cute image factor, factor 2 is a charming image factor, factor 3 is a transversal factor, Factor 4 is active image factor, Factor 5 was classified as a longitudinal factors. Second, analyzed by the visual evaluation according to the shape and length of the skirt, 20-30s women's most preferred form of the skirt is pleated skirt which was highly evaluated looks good, beautiful, favorite, attractive factors. Non-prefered skirts are gored skirt which was highly evaluated not corny, not pretty, heavy, unattractive factors and gored skirt which was negatively evaluated with classic and dislike factors. In the length of skirt, the knee length short skirt is attractive, active and positively evaluated by the 20-30s women than long skirt. Therefore, the results of this study, there are almost no differences according to the age groups of 20-30s women. They are more affected from the length of the skirt rather than the shape.

This study aimed to find the components of visual image by researching main image-related adjectives applied to high-waist skirts. In addition, it compared and analyzed the differences and mutual influences of visual images according to variations in the waistline and skirt length of high-waist skirts. The researchers made nine high-waist skirts-combinations of three different levels of waistlines and skirt lengths. The test involved 121 people who hold degrees in the field of Clothing and Textiles. The panels tested actual images of all models wearing the high-waist skirts shown on a computer screen. The results of the study are as follows.: Four factors affected the visual image as waist-height and skirt-length changed: attractiveness, upper-body compensation, length compensation, and hips compensation. Among these factors, attractiveness was estimated as the most important factor. The torso and the hip were highlighted as the waistline increased from 3cm to 11cm, due to the optical illusion of a tighter skirt wrapping the bust, waist, and hips. As the waistline increased, the stature and leg length increased, possibly revising the overall appearance. For the skirt length, a length measuring 20cm above the knees, proved to be most attractive. This resulted in elongated height and leg length, and a slimmer overall look.

유량조절을 위한 자동수문은 설정된 관리수위 이하에서는 수문이 개방되지 않으며, 유량이 증가하여 관리수위 이상이 되면 수문이 개방되어 방류를 시작하여 일정 수위를 유지하는 것을 의미한다. 자동수문의 운영 중 수문의 거동과 자동 개폐 시점을 예측하는 것은 정밀한 수문 설계를 위해 매우 중요하다. 수문 하단으로 흐름이 발생하면 수문 선단을 포함한 주변에서의 압력 차이로 인한 동수압 하중이 발생하고 진동을 유발, 수문 개방을 억제하는 하향력 등의 효과로 수문 운영에 큰 영향을 미친다. 본 연구에서는 부력식 수문의 모형실험을 통하여 정수압 상태의 부력 이론에 의한 수문 개방률과 측정에 의한 수문 개방률을 비교하였으며, 이론과 측정 수문 개방고의 차이를 하향력에 의한 효과임을 확인하였다. 부력식 수문의 하향력을 검토하기 위해 기존 이론식을 이용한 결과, 이론식은 부력식 수문에 적용하기 어려운 것으로 나타났다. 따라서, 기존 이론식을 이용하여 부력식 수문의 하향계수 산정을 위한 매개변수 관계식을 개방률을 이용하여 제시하였다. 제시된 매개변수 관계식의 결정계수는 0.721, 수정된 결졍계수는 0.690으로 나타났다. 부력식 수문의 형상비에 따른 하향력을 검토하기 위해서 수치모의를 수행하였다. 모형실험에서 측정된 자료와 수치모형 ANSYS-Fluent의 사용성을 검증하였고, 부력식 수문의 형상비를 0.24, 0.49, 0.69, 0.89, 1.09로 총 5가지로 설정하여 하향계수와 하향력을 분석하였다. 부력식 수문의 하향계수와 하향력 검토는 부력체, 스커트로 구분하여 분석을 수행하였다. 하향계수 분석결과, 하향계수는 개방률이 증가함에 따라 감소하였으며 하향계수가 부력체 부분에서는 0.465~1.542, 스커트 부분에서는 0.058~1.148의 범위로 나타났다. 하향력 분석결과, 하향력은 개방률 0.300 이하에서는 개방률이 증가함에 따라 하향력은 증가하였나 개방율 0.300 초과하면서부터 개방률이 증가함에 따라 하향력이 감소하는 것으로 나타났다. 또한 부력체 부분에서는 형상비가 증가함에 따라 하향력이 감소하였으나, 스커트 부분에서는 형상비가 증가함에 따라 하향력이 증가하였다. 이는 형상비가 증가함에 따라 스커트 부분의 면적이 증가하기 때문이다. 부력식 수문의 전체적인 하향력을 계산한 결과, 부력식 수문의 하향력은 0.002~0.015 kN의 범위를 가지며 형상비가 증가함에 따라 부력식 수문에 발생하는 하향력은 증가하는 것으로 나타났다.

The purpose of this study is to evaluate the differences of visual image by variations in the volume of flare and the length of flare skirt. The stimuli are 12 samples: 4 variations of volume of flare and 3 variations of the length of skirt. The data has been obtained from 181 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 image by the volume of flare and the length of flare skirt are composed of 4 factors : matureness, attractiveness, stiffness and softness, moderateness. In these factors, matureness is estimated by the most important factor. When the volume of flare is $180^{\circ}$, the visual images are shown to be better. As the skirt gets shorter, it has more vivid and attractive image. And as the skirt gets longer, it looks older and gentle but not too plain or ordinary. The volume of flare and skirt length interact with each other in matureness and attractiveness factors. But the volume of flare affects more in stiffness and softness and moderateness factors than skirt length.

This study verified the 'Hemline Index' theory by George (1926) and established a new fashion theory frame to forecast future fashion cycles of skirts by analyzing the past fashion cycle of skirts through a diachronic method. Skirt pictures from 1980-2013 (the post-industrialized period of Korea) were analyzed and representative skirt styles, the fashion cycle of skirts and relation between skirt style, length, width and stock index were identified. A total of 1496 pictures in fashion magazine published over 34 years were selected and analyzed using PASW 18.0. The results were: For 34 years, representative skirts styles were mini skirt, midi skirt and long skirt. Fashion trend cycles of skirt length decreased for 10 years and the fashion cycle showed a trend to shorten. Skirt length & stock index related negatively and skirt length & skirt width related positively. All relations revealed significant results. Finally, the 'Hemline Index' theory of George (1926) was verified. Fashion marketers can develop successful and suitable products using a fashion cycle theory based on the results of this study.
