  • This study aims to find the optimal skirt dimensions for a composite pressure vessel with a separated dome part. The size optimization for the skirt structure of the composite pressure vessel was conducted using a sub-problem approximation method and batch processing codes programmed using ANSYS Parametric Design Language (APDL). The thickness and length of the skirt part were selected as design variables for the optimum analysis. The objective function and constraints were chosen as the weight and the displacement of the skirt part, respectively. The numerical results showed that the weight of the skirt of a composite pressure vessel with a separated dome part could be reduced by a maximum of 4.38% through size optimization analysis of the skirt structure.

  • The purpose of this study was to survey the high school girls' alteration of school uniforms concerned about both size satisfaction and dissatisfaction and to improve the size of school uniforms. The subjects were 1,007 girls attending high schools in Cheju. The questionnaire survey was done from July 8th to Sep. 21th, 2001. According to the survey, 67.3 percentile of the interviewed girls alterated their uniforms. It was appeared that they alterated skirts more than blouses as a way of shortening. The main reason of alteration is ill-fitting uniforms, most of girls had a positive idea to alterate uniforms. Dissatisfaction of uniforms is mainly caused by the large size not by the small size. It was appeared that dissatisfaction rate of skirt was higher than that of blouse. The large part of dissatisfaction was appeared on waist circumference of blouse and hem circumference of skirt. The girls who experienced alterating the part of uniforms such as waist circumference of skirt, skirt length and hem circumference had high satisfaction rate. And a result of analyzing the level of satisfaction with uniforms-size-satisfaction/dissatisfaction showed the significant differences in fashion, factors-aesthetics and factors-activity of skirt and blouse.

  • The study purpose was to increase Han-bok's convenience by changing materials while maintaining keep the traditional Han-bok style. For this purpose we surveyed actual Han-Bok wearers about the inconveniences of its form and design by combining knit with Han-bok. On the basis of this survey, we present a practical design for use in daily fife. Responding to the question about Jeo-Go-Ri(jacket), most respondents preferred a Han-bok which stressed elasticity by utilizing knit on Jeo-Go-Ri's front and back body line(JD1, JD4). For the question about ann holes, most respondents liked a design which substituted knit materials for Sam-hoi-jang(colorful strips) to ensure ease of use and shorten both the width and length of the breast-tie(JD2, JD3). For the sleeve edge, they preferred a design which solved the difficulties of rolling up the sleeve when working ($JD2{\sim}JD5$). Regarding the most inconvenient aspect of wearing Chi-mas(skirts), the respondents indicated tightening of the breast and an uncomfortable feeling due to the skirt length. This suggested that the waist of the vest should be lengthened to avoid the feeling of pressure(CD2, CD5). Regarding changes to the skirt shape the respondents preferred buttons and hooks rather than using skirt strings(CD4, CD5).

  • The present study deals with the Pressure-settlement behavior of square and rectangular skirted footing resting on sand and subjected to a vertical load through a laboratory experimental study. A series of load tests were conducted in the model test tank to evaluate the improvement in pressure-settlement behavior and bearing capacity of square and rectangular model footings with and without structural skirt. The footing of width 5 cm and 6 cm and length/width ratio of 1 and 2 was used. The relative density of sand was maintained at 30%, 50%, 70%, and 87% respectively. The depth of skirt was varied from 0.25 B to 1.0 B. All the tests were carried out using a strain controlled loading frame of 50 kN capacity. The strain rate for all test was kept 0.24 mm/min. The results of present study reveal that, the use of structural skirt improves the bearing capacity of footing significantly. The improvement in bearing capacity was observed almost linearly proportional to the depth of skirt. The improvement in bearing capacity of skirted footings over footing without skirt was observed in the range of 33.3% to 68.5%, 68.9% to 127% and 146.7% to 262% for a skirt depth of 0.25 B, 0.50 B and 1.0 B respectively. The skirted footings were found more effective for sand at relative density of 30% and 50% than at relative density of 70% and 87%. The bearing capacity was found to increase linearly with footing width for footings with and without skirts. This observation was found to be consistent for footings with different skirt depths and for relative density of sand i.e., 30%, 50%, 70%, and 87%. The obtained results from the study for footing with and without skirts were comparable with available solutions from literature.

  • The purpose of this study was to find out apparel fit satisfaction according to item(jacket, pants, skirt) by body perception and body satisfaction. This research was done by a survey method. Descriptive Statistics, Pearson's Correlation, Crosstabs were used for data analysis. The results of this study are as follows. 1) Correlation between body perception and body satisfaction : The subjects were less satisfied with larger or thicker girth of upper body. The subjects were less satisfied with thicker upper arm, lower arm, waist and lower abdomen. The subjects were more satisfied with taller height. The subjects were less satisfied with larger or thicker girth of lower body. The subjects were less satisfied with thicker hips. thighs, calves, ankles, and longer crotch length. However, they were more satisfied with longer legs. 2) Apparel fit by body perception and body satisfaction: The subjects who were less satisfied with thicker upper arm, waist, thighs and wider hips were less satisfied with the upper arm area, waist area. hip area of jacket. The subjects who were more satisfied with longer arms were more satisfied with the sleeve length of jacket. The subjects who were less satisfied with wider shoulder width were less satisfied with the upper back width of jacket. It means the shoulder width affected more the upper back width of jacket than shoulder width of jacket. The subjects who were less satisfied with wider hips were less satisfied with the hip area of pants and skirt. The subjects who were less satisfied with thicker thighs were less satisfied with the thigh area and the hip area of pants and skirt. The subjects who were less satisfied with longer crotch length were less satisfied with the crotch length of pants. 3) Difference between actual body and perceived body by Rohrer Index: Rohrer Index 109 calculated by average of the ideal height(165.83cm) and weight(49.78kg) of the subjects ranged in thin body type(below 120). The subjects tended to perceived their bodies fatter than their actual bodies. Also, the subjects tended to perceived their lower bodies fatter than upper bodies.
