In this study, in order to examine the applicability of computational fluid dynamics with the porous model to the analysis of APR+ (Advanced Power Reactor Plus) internal flow, simulation was conducted with the commercial multi-purpose computational fluid dynamics software, ANSYS CFX V.14. In addition, among the various reactor internals, the effect of flow skirt geometry on reactor internal flow was investigated. It was concluded that the porous model for some reactor internal structures could adequately predict the hydraulic characteristics inside the reactor in a qualitative manner. If sufficient computation resource is available, the predicted core inlet flow distribution is expected to be more accurate, by considering the real geometry of the internal structures, especially located in the upstream of the core inlet. Finally, depending on the shape of the flow skirt, the flow distribution was somewhat different locally. The standard deviation of the mass flow rate (${\sigma}$) for the original shape of flow skirt was smaller, than that for the modified shape of flow skirt. This means that the original shape of the flow skirt may give a more uniform distribution of mass flow rate at the core inlet plane, which may be more desirable for the core cooling.

This study was intended to identify the constructing factors and hierarchy of images in the gathered skirts, which is expected to be helpful in shape classification. The gathered skirts were made by different gathering conditions: three kinds of the gathers ratio(1.5T, 2.0T, 2.5T) and different fabrics(cotton, mixed wool, polyester). 45 undergraduate and graduate women students responded to the nine gathered skirts during December in 2004 to February in 2005. 184 words expressing gathered skirt were collected through the investigation and analysis of questionnaires. 32 words arranged in based on the standard form with frequency before conducting factor analysis to identify the constructing factors of gathered skirt images. As a result of factors analysis, 2 factors-H shape, A shape were found out as constructing factors of gathered skirts. To explain the hierarchy of gathered skirt images, cluster analysis was applied. To observe the association of 32 words, dendrogram was introduced, and to interpret the result, five sub clusters were determined. This 5 clusters were continuously combined according to their frequency, based on the factors marks. Two major division of image clusters were 'simple and neat image', and 'fairly good and feminine image'.

Long bridges, such as suspension bridges and diagonal bridges, are complex phenomena that show different behaviors depending on the shape and rigidity of the cross sections, such as wind vibrations and liquid vibrations from earthquakes in liquid storage containers. This is called the lower skirt on the lower side of the bridge, and the installation of lower skirt is effective for release and vortex vibrations caused by rapid winds, and that increases the stability of the wind resistance of the bridge. Optimal shape and installation of the lower skirt is also essential to make maximum wind speed effect of the lower skirt. Therefore, this study proposes a numerical analysis method to control the vibration of a bridge by calculating the optimal installation angle of an optimal lower skirt according to the optimal control theory and this study evaluates the impact on the optimal control system by minimizing the dominance equation with an evaluation function,which is an indicator for evaluating the optimal control theory state.

The purpose of this study is to find the optimum skirt size for a composite pressure vessel using optimum analysis technique. The size optimization for skirt shape of a composite pressure vessel was conducted using sub-problem approximation method and batch processing codes programmed by APDL(ANSYS Parametric Design Language). The thickness and length of skirt part were selected as design variables for the optimum analysis. The objective function and constraints were chosen as weight and displacement of skirt part, respectively. The numerical results showed that the weight of skirt of a composite pressure vessel would be saved by maximum 4.38% through the size optimization analysis for the skirt shape.

The purpose of this study was to detect the effect of the lower body type on the shape of flare skirts. The subjects for the wearing test were 50 female students, who were controlled in their hip and waist shapes. The skirts used for wearing test were six types(three flar angles $\times$ two fabric types). The effect of lower body type on the shape of flare skirts was determind by the hemline trace method and the silhouette photography. The data were then analyzed by the repeated measures of analysis of variance and the SNK multiple range test. The results obtained from this study were as follows : 1) When a flare skirt made with larger flare angle and better drapable fabric was worn, the numeric of the nodes increased as the drop value(hip - waist) increased. When a flare skirt made with smaller flare angle was worn, the width of horizontal sectio of hemline increased as the drop value increased. The hemline uneveness decreased on the sides and back as the drop value increased. When a flare skirt made with worse drapable fabric was worn, the sides angle of the flarskirt increased as the drop value increased. 2) When a flare skirt made with larger flare angle was worn, the numeric of nodes increased as the ratio of dropped hip increased. The wave-height increased and the back variation ratio of wave-height was higher than the front variation ratio of wave-height as the ratio of dropped hip increased. The hemiline uneveness decreased on the back as the ratio of dropped hip increased. When a flare skirt made with larger flare angle was worn, the sides angle of the flare skirt increased as the ratio of dropped hip increased.

This study compared and analyzed the interaction visual effect of skirt silhouettes and skirt length by body mass index. This study provides basic data for women in their 20s and 30s to choose suitable skirts for their image. Twelve skirts were made, consisting of two categories of body mass index, three types of skirt silhouette and two levels of skirt length. Men and women in their 20s and 30s evaluated the visual effects of the experimental skirts using a questionnaire. The interaction effect of the visual effect following the skirt's length and silhouette by body mass index were analyzed by three-way ANOVA. Overall, a shorter the body and lower body length resulted in better vertical effects in normal weight. In terms of horizontal effects, such as lower body thickness and full-body shape, the 40 cm skirt, 50 cm tight, and A-line skirt were generally shown as better images. Skirt length helped supplement body type rather than silhouette in the overweight section. When the length was 40 cm, three skirts showed a more positive image. This study provide results for women in their 20s and 30s to choose skirts that are suitable for their image.

We studied the 3D simulating shapes of the flared skirt using NARCIS-Drape Simulation software made in Korea D&M FT. The experimental conditions were made of three types of cuttings (lengthwise, crosswise, 45 bias) and polyester fabrics for flared skirt (light, medium, heavy) and different simulating repetitions (1, 2, ${\cdots}$, 9, 10 times). We accomplished some experimental data on the 3D simulating shapes of the flared skirt made by different conditions. The 3D simulation shapes of the flared skirts were gradually getting stabilized from 5 repetitions. And the length of skirts and the width and depth of hems diminished lower by degrees as the simulating repetitions. It is considered that the simulating repetition for the flared skirt was appropriate in the range of 8 to 10 times. But it was not reasonably showed that the difference in the drape of the flared skirt was made by different cuttings and fabrics.

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.

Study is a basic analysis of a future virtual clothing system based on a comparative analysis of all the shirring, using a 3-dimensional apparel cad system. Frilled skirts shirred at the lower hemline were the subject of this study for a comparison of expression and shape of shirring. It compared the silhouette and details expressed in virtual and real skirts made of woolen fabrics and polyester satin, with different widths (1.5, 2 and 2.5 widths). It was found that the virtual skirt could not express shirring as exquisitely as the real skirt due to fabric thickness and other fabric characteristics. In addition, the increase in widths caused the frill shape to deform badly. In the case of a virtual skirt made of polyester satin, the increased multiplication factor let the frill spread out sharply (unlike the real skirt). Simulated skirts of polyester satin and woolen spread out to the sides with the sidelines of their frills hanging down markedly (unlike the real cloths) when the frills changed from 1.5 widths to 2 widths. When it came to the virtual skirt, side-line from the hip down all the way short of frill contorted with the wrinkle multiplication factor of 2 and 2.5 widths. This phenomenon was more notable in polyester satin skirts than in woolen skirts.
