The objectives of this study were to identify fashion trend in the late 1990's by using content analysis of the design elements of wedding dresses in wedding magazine photographs. The data were selected among the wedding dress photographs in 1997 issues of two wedding's magazines, 'My wedding'and 'She's Bride'. The identified 455 photographs were classified into 15 major-categories of silhouettes, necklines, sleeves, materials, and trimmings, etc. 15 major-categories were consisted of 232 sub-categories. In the late 1990's, fashion trends of wedding dresses have mixed mainly dome silhouettes(56.0%), bell silhouettes, and tubular silhouettes. One-piece forms(90.8%) were familar more than two-piece forms. Necklines were used mainly such as square neckline(14.0%), high necklines(13.0) blended with other off-shoulder necklines, heart-shape necklines, and sweet-heart necklines, etc. Also camisole and strapless were added in neckline. Long-tight sleeves dominated at the late 1990's because that were used most (21.1%) among 22 sleeves sub-categories. And short sleeve, ruffled below-elbow length sleeves, and french sleeves were also used with the other sleeves. Long length in skirts(98.4%) were common but mini length were used rarely. Satin, lace, and solid cloth were the main materials in wedding dresses, however, spandex and velvet were also used. Various trimmings such as flowers(corsages), ribbons blended with embroidery, small flowers, buttons, frills, strings, and fur trimming are used. Especially, flowers used most(11.8%) among 61 trimmings sub-categories. But simplicity was shown in trimmings because there were dresses not having any decorations(14.3%). The wedding dress of the late 1990's has become more varied in design due to the reflection of changes in society and fashion of everyday garments while the traditional design of the wedding dress has been preserved.

In order to evaluate the effect of structural degradation of a GFRP composite bogie frame due to ballast-flying phenomena, the impact test and residual compression test after impact was conducted for glass fiber/epoxy 4-harness satin woven laminate composites applied to skin part of a bogie frame. The impact test was performed using a instrumented impact testing system with energy levels of 5J, 10J, and 20J, and the impactor was designed to have various ballast shapes such as sphere, cube, and cone to consider the ballasted track environments. The residual compression strength was tested to evaluate the degradation of mechanical properties of impact-damaged laminate composites. The results showed that the damage area and the degradation of residual compressive strength after impact for laminate composites was increased with increase of impact energy for all ballast shapes, and was particularly most influenced by ballast shape of cone.

The purpose of this paper is to examine the possibility of weight reduction by changing the partition panel of vehicle from an existing aluminum material to carbon fiber reinforced plastics. Three weaving methods (plain, twill and satin) were used in the manufacture of composite materials, and they were produced and tested to derive their material properties. The analysis model of composite partition panel for torsional conditions was developed and the structural stability and system stiffness were evaluated according to Tsai-Hill failure criteria. With design variables for fiber orientation angles and stacking sequence, evolutional optimal algorithm was performed and as the results, the optimal composite partition panel was designed. In addition, the structural analysis results for strength and specific stiffness were compared with aluminum partition panels and composite partition panels to verify the possibility of weight reduction.

This paper describes the optimum design of bolt locations for metal joint parts of railway bogie frame made of glass fiber/epoxy 4-harness satin woven laminate composite and PVC foam core. The optimum design analysis was done by sub-problem approximation method using Ansys Parameter Design Language(APDL). The sub-modeling method was introduced to conduct the detailed recalculation for the only target parts and reduce calculating time. The structural analysis for composite bogie frame was performed according to JIS E 4207. The results showed that the optimum design analysis using sub-modeling method was able to obtain faster and more precise results than that of the entire model by the control of mesh size for the target parts, and the maximum Von-Mises stress has been reduced in comparison with its original dimensions due to the optimum design of bolt locations.

Abstract The effects of the hole size and the specimen width on the fracture behavior of several fabric composite plates are experimentally investigated in tension. Tests are performed on plain woven glass/ epoxy, plain woven carbon/epoxy and satin woven glass/polyester specimens with a circular hole. It is shown in this paper that the characteristic length according to the point stress criterion depends on the hole size and the specimen width. An excellent agreement is found between the experimental results and the analytical predictions of the modified failure criterion. The notched strength increase with an increase in the damage ratio, which is explained by a stress relaxation due to the formation of damage zone. When the unstable fracture occurred, the critical crack length equivalent for the damage zone is about twice the characteristic length. The critical energy release rate $G_c$ is independent of hole size for the same specimen width. The variation of $G_c$ according to the material system, fiber volume fraction and specimen width relates to the notch sensitivity factor. $G_c$ increases with a decrease in the notch sensitivity factor, which can be explained by a stress relaxation due to the increase of damage zone.

The purpose of the study is to give new aesthetic values of black dress one of the important items in contemporary women＇s fashion. Through the work, to give the new aesthetic characteristics that women really needed can be found. This study was processed by fashion books and articles, literal material with fashion photos which were related fashion trend from 1920 to the present. The results are as follows: In early 20th century, the black dress, which had simple form pursuing function like little black dress. In the middle of the 20th century, elegance and minimalism was represented by black dress, expressed erotic images together with see-through fabrics. In the end of the 20th century, body conscious style of black dress expressed sensual images of women. Modem black dress has design characteristics of the form: simple, close, exposure type and of the materials: matte, transparent and dazzling etc. Simple type emphasizes feminine elegance, while close type and exposure type disclose woman body curve to express erotic images. Matte materials made black dress express feminine elegance while transparent materials and dazzling materials made black dress express erotic and sensual beauty. The aesthetic characteristics of black dress were as followings: Sensualism expresses sexual attractiveness of women-close type and exposure type black dress and see-through materials and dazzling materials made black dress. Simplicity of extreme decoration effects are expressed through black dress having temperate and simple form. Femineity expresses traditional femineity to emphasize chaste, modest and elegant women images-the black dress, which is made of simple form, velvet and satin materials. Modernism combines black colour, which is called modem colour, with simplicity and function factors and pursues simple form. Ascetic practice controls mental and physical desire of the individuals, simple form without decoration covering up woman body and box type silhouette of black dress. Therefore, the study on image of the black dress, which have made appearance at modern fashion, is thought to help develop fashion trends and design, through which modern women express themselves and their beauty.

The objective in the part H of this study was to investigate the effects of materials, sleeves, trimming, and perceivers gender on impression formation. Stimuli consisted of 13 color photographs of a female model wearing a wedding dress which were manipulated according to clothing cues. A semantic differential sale of 4 dimensions was used. These were attractiveness, neatness, femininity, and prettiness. Samples were 312 males and females. For the effect of sleeves, there were significant main effects in attractiveness, femininity, neatness, and prettiness. Three-quarters lace ruffled sleeves increased the perception of positive attractiveness, femininity, and prettiness. Flounced sleeves had a positive effect on the perception of neatness. Long-tight sleeves had a negative effect on the perception of attractiveness, femininity, and prettiness. Sleeveless dresses increased the perception of negative neatness. There was an interaction effect between sleeves and the perceivers gender on neatness. For the onぉ of material, there were significant main effects in neatness, femininity, and prettiness. Solid cloth had a positive effect on the perception of neatness and negatively on prettiness. The combination of lace and solid cloth increased the perception of positive femininity and prettiness. lace had a negative effect on the perception of neatness. Satin increased the perception of negative femininity. There was an interaction effect between material and perceivers gender on prettiness. The main effect of trimmings was its effect on prettiness. Ribbons increased the perception of positive prettiness. Not having any trimmings had a negative effect on the perception of prettiness. There was an interaction effect between timings and the perceivers gender on neatness. The results of this study confirm that image perception of wedding dresses becomes different according to the materials, details, and perceiver's gender.

Although some degree of mechanical properties of suede fabrics mainly related to non-woven suede fabric has some researched, the thin suede fabric has rarely been researched. In this study, polyester(DTY 50/72) was used for warp, and after producing latent yarn and sea-island yarn for weft, two yarns were compounded to produce sea-island DTY yarn. By using the two produced yarns for warp and weft, we produced thin suede fabric with stretch function. For weft 2ply, weft density 85, 90, 100(picks/in) were applied to weave fabric, and for weft 1ply, weft density 125, 135, 140(picks/in) were applied to produce weft face 5-end satin weave. The mechanical properties of the produced fabric were researched. The result are as followed. The weight loss ratio of the suede fabric produced for this experiment reached 15% on the conditions of temperature $90^{\circ}C$ and 20 minutes, so that island parts were completely separated. The strength of weft 1ply applied suede fabric was about 7.5kg and that of 2ply suede fabric and about 3.5kg. But the strain of two samples ranged from about 40 to 43%. Although Hari was high when weft was denser. The values of Koshi and Kisimi were low. And shear stiffness was high when sea-island DTY yarn was used. The WC value was higher in the case of 2ply than in that of 1ply sea-island DTY yarn for weft, so that we may conclude that Fukurami was more affected in the 2ply case.

Analysis of the species of wood in the wooden materials and the chemical composition of the fabric of the clothing excavated from the tomb of Yi Jing (1580-1642) has determined that the wooden materials, including the coffin (內棺, naegwan), burial chamber(外棺, oegwan), chilseongpan(七星板, bottom-lining board), and fan-shaped slats were made of pine(Pinus densiflora). The analysis of the fabrics suggested that the cloth attached to the fan-shaped slats, the funeral banner with inscriptions, and the five pouches for the corpse (五囊, onang) were all made of silk. The jacket was made of plain-weave cotton, while the inner and outer cloth of the socks were made of cotton and hemp, respectively. Among the silk items, the pouches for the left and right feet (constituting the five pouches for the corpse) were made from a satin-weave figured silk, while the other silk items were made of ju(紬), or plain-weave silk fabric. Infrared analysis revealed that the fan-shaped slats were decorated with cloud patterns across the entire surface, while the funeral banner and the five pouches for the corpse bore ink inscriptions.
