As the demand of the consumer for high-sense clothing, relation with materials is becoming important even in clothing construction. Especially, the cutting angle of materials is becoming an crucial element in the formation of silhouette, and drape of Hem line, of skirts. Accordingly, in this study, Hem line shapes between real clothing and 3D virtual clothing of "i-Designer" were analyzed by manufacturing semi-flare skirts of polyester 100% according to a cutting angle, and the results are as follows. As a result of comparison of silhouette between the real clothing and the virtual clothing, the real and the virtual have a similar feeling regardless of a cutting angle. In case of drape shapes, both the front and the lateral side were represented in almost similar shapes. The back side, however, the real and the virtual showed a great difference in case of grain direction. And in the whole silhouette, the real and the virtual were represented similarly. It could be known that with regard to Hem-line drape shapes between the real clothing and the virtual according to a cutting angle, the real clothing is represented in a location farther from the body than the virtual clothing and, the location or number of node was similarly showed in the real and the virtual.

The world-view of a period or a society refers to the way it conceives of the order and governing principles of the universe. The ad and outcome of the crealive process of a designer reflect his or her world-view or value system. Contemporary students of design seem to find the traditional approach to art based upon the Euclidean logic rather redudive and confining and are trying to develop a new way of thinking and methodology, a new frame of reference. In this study, I am offering the chaos- and fractal theory, concepts drawn from science, as a new anchoring point for design. This approach makes use of the concept of chaos as the basis of a new, open system that enables a designer to find and generate numerous visual possibilities immanent in chaos. Likewise. fractal geometry is offering new concepts and vocabularies for the study of physical universe and design thinking, as well as bridging the gap between science and art. The number of structural possibilities fractal theory generates for environmental design seems to be virtually unlimiLl'd. In fine. this study places a great emphasis on the new approaches t() the environment we inhabit. which I hope will contribute to generating a greater number of creative possibililil:s for environmental design.

This study investigated the formability and appearance performance of 20 women's worsted fabrics. For this purpose, 10 foreign fabrics (9 Italian + 1 Japan fabrics) were prepared and 10 domestic worsted fabrics for women were made in Cheil woolen textile company for comparing with foreign fabrics. The mechanical properties of the 20 fabrics were measured using KES-FB and FAST systems; subsequently, fabric formability (F) and total appearance value (TAV) were calculated and compared with a virtual 3-D simulation silhouette by i-designer CAD system. The fabric formability of the domestic fabrics, calculated by KES-FB system, was lower than foreign fabrics, which was assumed to be caused by the stiff tactile property. The result was similar to that of the FAST system. Good wearing performance of the foreign worsted fabric was assumed to be caused by high extensibility and the compressibility of the fabrics. The TAV's of the domestic fabrics were also lower than foreign fabrics. Both the correlation between TAV and formability by the KESFB system and the correlation between TAV and formability by FAST system showed a good correlation coefficient. Fabric formability between KES-FB and FAST systems also showed a good correlation. The 3-D simulation silhouette of the foreign fabric by i-designer CAD system appeared superior to the domestic one, and assumed to be attributed to the low extensibility of the weft direction, stiff bending and high shear properties of the fabric.

This study investigated the formation of silhouette and hemline shape of knit flare skirts according to the properties of knit material through virtual clothing with a 3D virtual clothing system called i-Designer of Technoa, thus building a database of the property data of knit material to reduce the number of sample making steps repeated and implemented several times in the process of clothes making. The results would help to estimate a silhouette in advance, offer assistance to the development of original knit wear, and explore ways to provide basic data for the development of the knit industry of the nation. The investigator made 12 kinds of experimental clothes to the angles(width of skirt: $90^{\circ}$ and $180^{\circ}$), gauge(7G, 12G, and 15G), and grain directions(wale and bias direction) of experimental clothes for virtual clothing. The dynamic characteristics of knit skirt samples according to each gauge were measured with the KES-FB system. Draper shapes were analyzed with the sectional shape data of hemline based on i-Designer. As for the measurements of the sectional shape of hemline and the formation of silhouette, the number of nodes, the average height of node mountains and valleys, and the hemline width right and left and before and after increased at the angle of $180^{\circ}$ than $90^{\circ}$. As gauges multiplied, the number of nodes, and silhouette angle dropping. When considering grain directions, the number of nodes and silhouette index increased in the wale direction at the angle of $90^{\circ}$ with the number of nodes and silhouette angle increasing in the wale direction at the angle of $180^{\circ}$.

This study is designed to analyze the similarity of fit and appearance between 3D virtual torso length sloper with real torso length sloper according to three 3D virtual clothing simulation programs (Optitex, CLO 3D, i-Designer), three body types (A, N, H) and fit status. We selected three representative body type models of females aged 20~30 and got their direct body measurements. Using these body measurements, we developed three 3D avatar body models and made three torso length fitted sloper with long sleeves. Thirty expert fit judges consisting of technical designers and graduate students assessed the similarity of fit and appearance between 3D virtual clothing and real clothing by observing images classified into front, back and side scene. We conducted ANOVA and post-hoc analyses to compare fit and appearance between real clothing and virtual clothing depending on three program. The results showed that CLO 3D represented fit and silhouette most similarly among the programs, especially girths, width and length. i-Designer tended to be relatively good to represent stress fold amount and silhouette. Optitex was assessed relatively better in expressing ease amounts in torso girths and armscye girths, but relatively worse for width, length, stress fold amount and silhouette.

Patterns are something that comes out of necessity in human life, which is closely associated with it. Thus come the SFAA (Seoul Fashion Artists Association) collection which uses patterns varying in form, color, way of expression and material. For this research, I first categorized the patterns the SFAA designers used into: natural patterns, symmetric patterns, traditional patterns, stripe, plaid, dot and abstract patterns. As a result of the process. the designers most favored the natural patterns and symmetric patterns, and dot patterns were rarely used. The designer who most favored patterns in general was Sul Yun-hyoung, and the designer Kim Chul-ung rarely favored the surface effect. The seven kinds of patterns naturally differ according to the designer. as Park Hang-chi liked to use the plaid patterns along with yam dyeing material, whereas Jin Teok expressed stripe patterns using the yarn dyeing fabric. Natural patters were presented in a bizarre way with Lie Sang-bong. who took the motives appearing in Eastern ceramic and paintings into the clothes, using the print method. The symmetric patterns, which the SFAA designers most preferred. was used evenly among designers like Chang Kwang-hyo, Gee Choon-hee. Rubina, and Haneza. In contrast. Lie Sang-bong. who used abstract patterns that do not give out meaning of the actual form of the pattern. rarely used symmetric patterns. The dot patterns were most often used by Park Youn-soo. and traditional patterns were overwhelmingly chosen by Sul Yun-hyoung. Secondly. in expressing the colors, SFAA designers were much more likely to choose achromatic colors. not choosing to show off colors. This is especially apparent in works by Haneza and Lie Sang-bong. In the SFAA collections, numerous methods were used to create. For instance, Sul Yun-hyoung used the oriental embroidery method. and Rubina and Lie Sang-bong used many unique dying methods. In terms of materials, Sul Yun-hyoung preferred silk. due to her methods, and Lie Sang-bong was one of the designers that used a number of different materials such as vinyl. Jacques Mueclier of the Paris Clothes Association in France, who was invited to SFAA collection once, remarked. "While the choice of material and the actual sewing done were excellent, there lacked much difference among the designers, as most of them choose flowing silhouette In terms of composition," which is all too correct. In addition, there were cases in the collection where the inherent feelings of cultural artifacts was expressed without alteration. Summing up, the research aimed to analyze the surface expression methods, forms and color of SFAA designs. and I hope that it can open up ways for new projects in the future.he future.

The purpose of this study is to suggest designing goals and directions in the lobby area of obstetric hospitals by constructing a space evaluation structure model, which is made by image evaluation structure model used by SD method and Advanced Repertory Grid Technique. As a result of the image evaluation used by SD method, it turned out 4 factors which are related to recognizing and evaluating the space formativeness, openness, decorativeness, sensitiveness. I found out the relationship between space evaluation structure and the element of interior space. I also suggested detailed designing method based on this relationship. Space evaluation structure model can be applied to designing lobby areas of obstetric hospitals to reconstruct more specific and objective designing goals and standards rather simply designer's sensitive and abstract designing approach.

This paper described design as a purposeful human activity for solving its problems. This means, problem solving is finding a way to get from some initial situation to a desired goal.In order to do this, like a voyage, there should be a compass, and a route map to guide the designer through the design process. Evaluation gives information about the way a design is proceeding and suggests the direction in which change should be made in order that the complex of design concepts should be fulfilled in a satisfactory manner.I think Pugh's total design model discussing in this paper takes a layered approach through a series of sequential actions, part of which is to find the product status. Each layer has the $$\mu$ti-dimensional elements, Product Design Specification (PDS) around the design core. I made a comparative study of several evaluation tools wi th Pugh's model and examined the criteria for evaluation and the rating / weighing methods.It needs, however, more study in order that PDSs may have its values and be fixed from the dynamic design concepts.
