Metal materials have been used in the clothing design on the spirit of ingenious experiment by fashion designers, and they have been put to practical use by several designers who work out a scheme of popular fashion merchandise. This current starting from the 1960s was weakened in the 1980s, but it was appeared with various shapes of metal materials in the 1990s due to a popularity of techno/cyber fashion. Recently, textile engineering technology causes to develop new-materials which are practical and sanitary. The development of fashionable metal materials brings about the popularization of fashion with metal materials, and it induces that mainstream of modem fashion has been changed into designers of pursuing the spirit of ingenious experiment. This study examines the formative characteristics of metal materials that are based on the spirit of ingenious experiment. As a result, it is evaluated that the formative of metal materials shown in modern fashion is futurism, visual concentration, avast-garde, resistance, precious.

This study is to enhance the competitiveness of the domestic cosmetic industry and provide basic materials needed for a design idea by analyzing perfume bottles designed by Rene Lalique. The methods of this study are documentary research and demonstrative research. The documentary research considered the theoretical background with a focus on related domestic and international literature, previous research, and Internet materials. The demonstrative research extracted photo materials of the bottle designs of Lalique from domestic and international web sites along with literature that classified them into shapes, colors, materials, and patterns that analyzed the general characteristics and chronologic changes. The results of this study are as follows. The curve-oriented shape was common and multi-colors were used more frequently than a single color in the 1910's. Colorless-transparent glass and a flower patterns were used frequently for materials and patterns, respectively. Lalique reflects this style in his bottle designs because the Art Nouveau effect in the 1910's. In the 1920's, curved and straight shapes had a similar percentage. The use of multi-colors and one type of glass bottle increased versus the 1910's. Similar to the 1910's, a flower pattern was used most frequently. This suggests that Lalique was influenced by the established Art Nouveau and was also interested in the Art Deco style, In the 1930's, an organic curved shape was common. Unlike the 1910's and 1920's, a single color was more common than multi-colors. The one type of glass bottle and a geometric pattern were common for materials and patterns, respectively. The Art Deco style was reflected in the bottle design of Lalique in the 1930's.

This study analyzes the current educational curricula in the field of Clothing and Textiles in order to develop appropriate educational methods and courses. We reviewed the curricula offered by 58 Clothing and Textiles Departments at four-year universities in Korea. We analyzed the educational content of each curriculum by dividing all of the courses offered into eight categories. The analysis was based on the information posted on the universities' Internet websites, and the analysis was performed by using descriptive statistics. The results of this study are as follows: First, the educational courses of the Clothing and Textiles Departments are composed of, 36.2% design, 20.4% production, and 14.5% textile categories. In comparison with the results of a similar study conducted in 1999, emphases on the design, distribution, and marketing categories have increased, while the emphases on the production, apparel material, basic knowledge, and consumption science categories have decreased. Second, in the case of the apparel material category, basic knowledge of materials constituted 18.5%, the largest part of the category. The average number of units offered in the area of apparel materials by the 58 Departments was 17 units per year. The curricula were found to vary by regions of the country. The universities located in the Chungcheong region offer more textile material courses, but the universities in the Capital region offer fewer textile material courses than other regions. Departments that are affiliated with universities that emphasize Art and Design have more courses on basic knowledge, dyeing and finishing, and fabric design than other universities.

This research was designed to investigate the preference to textiles for slacks of college students. 105 subjects majored in fashion design were surveyed. Subjects selected three favorite materials among 120 samples presented in swatch book and weighted frequency and percentage were added by order. The extent of preference was compared by season and sex. The results of this study were as follows: 1. College students preferred twill cotton Drill foremost as a textile for spring and fall season. 2. Plain linen Crash was the most preferred material for summer. 3. Cotton Corduroy was the most preferred textile for winter. 4. In thickness and weight, textiles for winter were thicker and heavier than those of other seasons. 5. In fiber content, natural fiber such as wool were preferred for all seasons. 6. In weave of textiles, twill weave fabric was preferred for spring fall and winter season, and plain weave for summer. 7. College students preferred plain texture materials foremost and navy blue and black color was preferred for textiles for slacks. 8. Girl students preferred cotton fabrics and boys preferred wool fabric for slacks. Also, girls generally preferred thinner fabrics than those of boys.

The biodegradation and water absorption properties of lignin/poly(vinyl alcohol) (PVA) nanofibrous webs are investigated. Lignin/PVA nanofibrous webs containing 0, 50, and 85wt% of lignin were prepared via an electrospinning process to observe the effect of the lignin concentration on the biodegradability and water absorption properties of lignin/PVA nanofibrous webs. The morphology of the materials was examined by field emission scanning electron microscopy (FE-SEM) and atomic force microscopy (AFM). To understand the wetting behavior and hydrophilic nature of the electrospun lignin/PVA nanofibrous webs, the water absorbency, contact angle, and water uptake were examined. The enzymatic degradation of lignin/PVA nanofibrous webs was investigated using laccase by measuring total organic carbon (TOC) concentration over a course of 50 days. Water drops were absorbed immediately into all of the specimens. The water uptake of lignin/PVA nanofibrous webs increased as the amount of PVA in the lignin/PVA hybrid webs increased. The enzymatic degradation experiment indicated that the inherent biodegradability of lignin was retained after its transformation into nanofibers. Our findings imply that blending these two types of polymers is promising because it can lead to the development of a new range of multifunctional materials such as antimicrobial absorbent nanotextiles based on sustainable biopolymers.

Mass-production caused by industrialization has led to environmental pollution; however, a potential solution to this problem is the Up-cycling fashion design belonging to the sustainable design category. This study analyzed the material characteristics of each brand fashion product by selecting 21 domestic Up-cycling fashion brands. The product types manufactured by domestic Up-cycling fashion brands could be divided into fashion clothing, bag, and fashion accessories. The materials used for each item included special material, waste fiber, waste leather, waste paper, and others. In the results of analyzing the material characteristics into the external characteristics and internal characteristics, the external characteristics included the durability with less abrasiveness and deformation as well as a mixture with other different materials, while the internal characteristics included a story arousing consumers' empathy, and scarcity without the same design due to the limitation of material.

This research explores consumer preferences for materials in different clothing product categories, using web-crawling and text mining techniques. Specifically, the study focuses on the material-related terms found in consumer reviews across three distinct product categories: functional clothing, formal shirts, and knit sweaters. Top-selling products within each category were identified on the Naver Shopping website based on the volume of reviews, and the four most-reviewed products were selected. Six hundred reviews per product were analyzed using the Textom big-data analysis software to determine the frequency of material-related mentions and word associations. The analysis utilized two comparative metrics: product category and usage duration. Our findings reveal notable variations in the material preferences mentioned by consumers across different product categories. The study suggests a need to re-evaluate existing standardized review criteria to better reflect consumer interests specific to each product category. Additionally, an increase in material-related terms in reviews over one month indicates the potential importance of extending the duration of product reviews to enhance the accuracy of information that reflects longer-term consumer experiences with material quality.

Several kinds of biodegradable hydrogels were prepared via in situ photopolymerization of Pluronic F127/poly($\varepsilon$-caprolactone) macromer and acrylic acid (AA) comonomer in aqueous medium. The swelling kinetics measurements showed that the resultant hydrogels exhibited both thermo- and pH-sensitive behaviors, and that this stimuli-responsiveness underwent a fast reversible process. With increasing pH of the local buffer solutions, the pH sensitivity of the hydrogels was increased, while the temperature sensitivity was decreased. In vitro hydrolytic degradation in the buffer solution (pH 7.4, $37^{\circ}C$), the degradation rate of the hydrogels was greatly improved due to the introduction of the AA comonomer. The in vitro release profiles of bovine serum albumin (BSA) in-situ embedded into the hydrogels were also investigated: the release mechanism of BSA based on the Peppas equation was followed Case II diffusion. Such biodegradable dual-sensitive hydrogel materials may have more advantages as a potentially interesting platform for smart drug delivery carriers and tissue engineering scaffolds.

The geometries, electronic structures and absorption spectra of the two organic triphenylamine-based dyes TA-St-CA and TA-DM-CA, containing identical electron donors and acceptors but the different conjugated bridges, were studied by density functional theory (DFT) at the B3LYP and PBE1PBE levels, respectively. The influence of para-orientating methoxyl units on the electronic structures and light absorption properties of the dyes and the consequent photovoltaic performance of the dye-sensitized solar cells (DSSCs) were investigated in detail. The results indicate that the introduction of the para-orientating methoxyl units into the conjugated bridge induces the increased absorption wavelength as well as the more negative EHOMO corresponding to the bigger driving force $(E_{I^-/I^-_3}-E_{HOMO})$ for dye reduction, which together improve the photovoltaic performance of TA-DM-CA, although there is a decline of the open circuit voltage caused by the more negative $E_{LUMO}$.
