The role of fashion image in modern society is being diversified from product planning to consumer satisfaction. In this research, after surveying female college students, the diversified modern fashion image was patterned. On the analogy of the relationship between these patterned image and design factors, the following conclusion was obtained. 1. The most popular styles are jacket and pants suits, three-piece outfits, tight mini-skirts and X-silhouette. Little decoration is used in general. simplicity is shown as trend by utility fabrics in single color-black, brown, beige and blue-with no pattern. Various materials such as wool, cotton, wool or cotton blended with other materials, silk, satin, knit, lace, vinyl and leather are used. 2. Fashion image is divided into four factors; factors that show fad, dignity, activity and simplicity. 3. Factors that show fad; style of tops, material of bottoms and length of bottoms reflect fad. blousons, three-piece outfits, pants rather than skirts, X-silhouette and mini-skirts are prevailing. Vinyl, leather, knit, lace and satin are the materials well used. 4. Factors that show dignity; Style and material of tops, the way of top and bottom pieces are matched and length of bottom or pieces reveal the characteristics. Jackets, blouses, half-coats and one-piece outfits rather than two-pieces are popular. Tight skirts in natural or midi length or pleated skirts are common. Wool, wool blended with other materials, leather and X-silhouette are design factors that reveal dignity well. 5. Design factors that show active image; Straight pants, three-piece outfits, T-shirts, shirt -blouses, vests, and blausons are popular. Knit and lace are used for tops, leather and vinyl are used for bottom pieces and cotton is widely used. Y- or H-silhouette are used to show active image.

Every year fish skin, bone and intestines are discarded as processing waste material. The use of fish processing waste material is more economical and environmental-friendly. The leather-like material was produced using shark intestine. Physical charactistics such as tensile strength, elongation, tongue tearing strength, and bursting strength of the leather-like material were measured, and compared with those of a commercial leather product. The values of tensile strength, elongation, tongue tearing strength, and bursting strength of the leather-like material were $3.3kg/mm^2$, $53\%$, 13.0kg/mm and $18kg/cm^2$, respectively. Elongation $(l09\%)$ of the leather-like material coated with lacquer was higher than that of a commercial leather material, and the other factors were similar. The tensile strength and tongue tearing strength of the leather-like material was higher than those of shoes leather, but bursting strength was lower. These results suggested a potential value to use the leather-like material from shark intestines as a substitute for commercial leathers.

The main purpose of this study was to examine factors affecting adolescents materialism and the relations between parenting, materialism and self-esteem in adolescents. The subjects were 439 first-grade high school students in Kang-nam area located in Seoul. The main results were as follows; (1) Material value was not significantly different according to gender, SES and parents education; (2) Adolescents whose parents are permissive or inconsistent have higher material value. On the other hand, adolescents whose parents are affectionate have relatively lower material value. And adolescents who communicate openly with their parents also have lower material value; (3) Lower material value was found for the adolescents whose self-esteem was high; (4) The mediating role of self-esteem was found: Adolescents self-esteem mediate the relations between parenting, parent-child communication style and material value of adolescents.

Although bonding material content of the high strength flowing concrete is very important in engineering properties, in rich mix concrete increasing the bonding material content may not follow more good properties. This study is to investigate the influence of the bonding material content affecting on the engineering properties of high strength flowing concrete, and this paper is to analyze the properties of hardened concrete. The results reveal that the strength of concrete having loss bonding material content is higher than that of concrete having more bonding material content, and that in proportion to increasing of concrete strength brittleness factors decrease, and that the static modulus of elasticity in this study is less than that in specification.

Stress and displacement fields for a propagating crack in a functionally gradient material (FGM) which has shear modulus as $\mu$=$\mu$$\_$0/(1＋ζX) are derived. The equations of motion in FGM which is nonhomogeneous material are different from those of homogeneous material. The stress intensity factors in stress fields have influence on odd terms of γ$\^$n/2-1/(n=1,3,5,...,) but stress at crack tip only retains term of γ$\^$-1/2/, where the γ is a radius of cylindrical coordinates centered at crack tip. When the FGM constant ζ is zero or γ→0, the fields for FGM are almost same as the those for isotropic material.

In this paper, transparent dynamic photoelastic experimental hybrid method for propagating cracks in orthotropic material was developed. Using transparent dynamic photoelastic experimental hybrid method, we can obtain stress intensity factor and separate the stress components from only isochromatic fringe patterns without using isoclinics. When crack is propagated with constant velocity, the contours of stress components in the vicinity of crack tip in orthotropic material are similar to those of isotropic material or orthotropic material with stationary crack under the static load. Dynamic stress intensity factors are decreased as crack growths. It was certified that the dynamic photoelastic experimental hybrid method was very useful for the analysis of the dynamic fracture mechanics.

In normal grinding abrasive particles of a grinding wheel rotate on planes parallel to the direction of workpiece fred. which may induce continued scratch lines on ground surface as the workpiece feeds. Instead in helical scan grinding the planes make an angle, called a helical angle, with the feeding direction. Thus scratch lines produced by abrasive particles per one revolution are discontinued which implies that the generation of scratch lines are suppressed by the helical scan grinding. In this study some experimental works have been done on the helical scan grinding of glass to find the effects of grinding conditions on the surface roughness and estimate the optimal grinding conditions. The helical angle, fred rate, material removal rate and the wheel speed are taken as factors for three kinds of grinding wheels i.e., coarse(#140 mesh), medium(#400) and fine(#800) diamond wheels. The experiments are scheduled by Taguchi technique and ANOVA has been carried out for the interpretation of the results. As a result of this study effects of the factors are verified quantitatively showing that the major factors are changed according to the wheel's mesh size and the helical angle is one of the influencing factors on the surface quality.

The wrinkling behavior of a thin sheet with perfect geometry is a kind of compressive instability. The compressive instability is influenced by many factors such as stress state mechanical properties of the sheet material geometry of the body contact conditions and plastic anisotropy. The analysis of compressive instability in plastically deforming body is difficult considering all the factors because the effects of the factors are very complex and the instability behavior may show wide variation for small deviation of the factors. In this study the bifurcation theory is introduced for the finite element analysis of puckering initiation and growth of a thin sheet with perfect geometry. All the above mentioned analysis and the post-bifurcation behavior is analyzed by introducing the branching scheme proposed by Riks. The finite element formulation is based on the incremental deformation theory and elastic-plastic material modeling. in order to investigate the effect of plastic anisotropy on the compressive instability a square plate that is subjected to compression in one direction and tension in the other direction is analyzed by the above-mentionedfinite element analysis. The critical stress ratios above which the buckling does not take place are found for various plastic anisotropic modeling method and discussed. Finally the effect of plastic anisotropy on the puckering behavior in the spherical cup deep drawing process is investigated.
