  • In this study, 25gsm melt-blown polypropylene nonwoven for dust-proof/medical masks was finished by the corona discharging treatment. The influence of corona discharging parameters on the filtration efficiency was investigated. Several parameters such as discharging voltage, discharging speed, distance to discharging wire and configuration of discharging system had an effect on filtration efficiency, while the parameters had no effect on breathing resistance. Optimum corona discharging conditions are as follows: Wires were installed on the upper part of the nonwoven and paper pipe was installed on the lower part of the nonwoven having a distance of 5cm. The sequence of wire voltages was +60 kV, +60 kV, 0, -60 kV, and -60 kV. The discharging voltage and speed were 60 kV and 30m/min respectively. The nonwoven treated by corona discharging at the optimum condition showed a filtration efficiency of 80% or more, which is suitable for dust-proof/medical masks.

  • Over the past decades, silk sericin (SS) received increasing attention in the academic and industrial fields. In nature, SS acts as a glue that holds the two strands of silk fibrils together. However, recent works suggest that SS might have a more diverse role during the silk spinning process, such as stabilizing the SF in the silk gland. On the other hand, the sericulture industry has been trying to find novel applications for SS discarded from the silk fabric manufacturing process. Recovery and refining of SS would be the first step of the recycling of SS. Using a proper solvent SS could be shaped into various forms, such as spherical beads, microparticles, fibers, and films. Moreover, the applicability of these SS materials has been investigated in various fields such as cosmetics, templates for nanomaterials, drug delivery, heavy metal adsorption, and enzyme immobilization.

  • In this study, the structural characteristics of sericin recovered from wastewater released from the silk textile industry (Plant sericin) were comparatively analyzed with those of sericin extracted from a silkworm cocoon produced in a laboratory (Lab sericin). To prepare Plant sericin, ethanol was added to wastewater (i.e., a sericin aqueous solution) after the degumming process to remove nonprotein materials, affording a sericin precipitate. To prepare Lab sericin, nonprotein materials were removed from a silkworm cocoon and sericin was subsequently extracted from the cocoon. Lab sericin and Plant sericin exhibited similar solution viscosities, gel strengths, and crystallinity indices, indicative of the similar molecular weights (MWs) of the two sericin samples. In the case of sericin powder, Plant sericin was more crystalline than Lab sericin due to its treatment with ethanol. The findings of this study revealed that sericin recovered from industrial wastewater can be used equally as its MW is similar to that of sericin obtained through laboratory-scale extraction.

  • The wave of Avant-garde swept away all in the unique social background so called 'October Revolution' and the early 1900 Russian society which was able to absorb and accept anything. The Russian avant-garde has been affected by the Cubism and the Futurism those had peculiarly appeared in the early twentieth century, spreaded out to three spheres: the Suprematism, the Rayonism and the Constructivism. The Russian Constructivism has appeared in this background, concretely and ideally ex-pressed the ideology of the revolution into the artistic form and made an huge influence to the whole Russian society. The Constructivist like Tatlin, naum Gabo, Pevaner, Rodchenko, Stepanova, Popova and Exter gave great effect on the Soviet Constructive fashion design in 1920's after the Revolution. The Soviet costume in 1920s hold in common the characteristicss of the Constructive graphic as it is, geometrical and abstractive form, energetic and motility. In fashion design, these graphic qualities have been showed as the application of geometrical form and architectural image, physical distortion and transformation. And in textile design, the simple, dynamical presentation has been appeared. We can classify the Soviet costume at this time into three occasions. The first term is from late 1910 th mid 1920, and it is altered from folk costume design to modern one. With Lamanova as the first on the list, using the folk mitif, the Constructive expression of simple form has been gradually revealed in design. Designers like Makarova, Pribylskaia and Mukhina produced the plane, simple chemise style with the decoration of the Russian traditional motif. From early to late 1920 is the second term, and it is at the pick of the most active processing of the Constructive design. Not only at the costume in daily life but also at the theatrical costume and textile, the con-structive design has been represented all avail-able fields. Many Constructivists including Stepanova, Popova, Exter and Rodchenko took part in the textile design and costume design so as to evlvo their aesthetic concept. The third term is from late 1920 to early 1930. The socialistic realism has dominated over the whole culture and art, the revolutionary dynamic motif has been presented also in textile design. The formative features of Soviet Constructive fashion design are; silhouette, from, motif, color and fabric. The first, the silhouette : a straight rectangular silhouetted has been expressed through the whole period and a volumed one with distorted human body shape has introduced in the theatrical costume design. The second, the form: many lengthened rectangular forms have been made at beginnings, but to the middle period, geometrical, architectural forms have been more showed and there are energy and movement in design. At the last period, only a partial feature-division has been seen. The third, the motif; no pattern or ethnic motif has been partly used at beginnings, a figure like circle, tri-angle has gradually appeared in textile design. At latter period, a real-existent motif like an airplane has been represented with graphing and simplicity. The fourth, the color ; because of insufficient dyeing, neutral color like black or grey color has been mainly covered, but after middle term, a primary color or pastel tone has been seen, contrast of the fabric; without much development of textile industry after the Revolution, thick and durable fabrics have been the main stream, but as time had going to the last period, fabrics such as linen, cotton, velvet and silk have been varously choesn. At the theatrical costume, new materials like plastics and metals that were able to accentuate the form. The pursuit of popularity, simplicity and functionalism that the basic concept of Constructive fashion is one of the "beauty" which has been searching in modern fashion. And now we can appreciate how innovative and epochal this Soviet Constructive fashion movement was.ement was.

  • Nowadays more than 200 countries are living on the earth in international relation. Having their own culture and history, these countries constitute international society, creating their national image with their own identity based on the culture and history. Though each country has cultural goods in which it combines its culture and history to economic area, the global and cultural goods representing a country is not made in short term, but completed by the combination of its long tradition, cultural consciousness of the nation and artistic level. That is to say, the image developed by the country is naturally embodied in the goods and the world recognizes the image and confirms the goods. To embody such Korean and global goods, it is essential to put priority on the research of history and culture of our society. Needless to say, it is very important to find the value of our own differentiated beauty and apply it to each area of design industry. Recognizing the differentiated value of our own cultural originality, this research performs the design of scarf and necktie to exhibit Korean image in modern and fashionable ways for commercialization by developing design of fashion and cultural goods to which Korean image is applied. Through literature and various informations, the theme of design that can best convey Korean image is determined to be the national flag of Korea, Taegeukki and five cardinal colors and the researching method is as follows. First, though the area of developing designs of cultural goods is very wide and various including commerce, industry, products , fashion, handicraft and traditional handicraft, etc., this research sets the scope of developing design, focusing on the fashion accessories utilizing the textile design such as costume, scarf, necktie and so on. Second, the definition and scope of cultural goods and the present situation of domestic cultural goods will be examined. Third, the modelling property and symbolic meaning of the national flag of Korea (Taegeultki) and five cardinal colors, the theme of design will be studied. Fourth, on the basis of above research, scarf and necktie will be designed by modern and fashionable design to which Korean image is applied. Fifth, this is textured in textile printing and gradation for commercialization.

  • The present study proposes a model for literature-based instruction within the context of a fashion design curriculum at a Korean university. The fashion design market continues to grow. The fashion design market now requires more cultural-bound strategies and efficient communication skills. The literature provides authentic resources and is highly relevant to the development of students' culture awareness as well as language awareness. Alice's Adventures in Wonderland written by Lewis Carroll contains various cultural contexts of the Victorian Era. The text provides explicit knowledge of the era depicted in both illustrations and satire languages. This study instructs students to analyze and interpret texts and illustrations so that they can engage critically and analytically in reading text to increase culture awareness and language awareness. The integration of literature and fashion design can provide students an opportunity to explore language choice and acquire refined knowledge of the target culture. Along with the text, illustrations in the literature provoke student's imaginative and creative thinking skills. Students can think and discuss many issues that deal with Victorian values and reinforce creative thinking skills. In the final stage, students can design fashion inspired by Victorian values and present their own designs using the acquired languages. This eventually leads students to adapt to a new notion for the fashion market and become competent communicators in the fashion world.

  • This study investigates customers' possession, usage, and satisfaction of newborn clothing, and analyzes their satisfaction with textiles of baenaet jeogori (the most basic Korean item of newborn clothing). The survey was conducted on 102 mothers with infants under 24 months old. The baenaet jeogori was the most commonly possessed item, followed by swaddling blanket, shirt and pants set, bodysuit, one-piece, and baenaet gown. About 52.6% of respondents used the swaddling blanket all day, 52% of respondents possessed 4-6 baenaet jeogories, and most respondents used the baenaet jeogori 4 weeks or more. Two most important selection criteria of the baenaet jeogori were textiles and season suitability which are closely related to functionality. Respondents were satisfied with the baenaet jeogori; however, there are a few problems with difficulty in putting and taking off as well as textiles. Most baenaet jeogories chosen by respondents were made of cotton and 68.8% of them were made of eco-friendly textiles. Respondents were dissatisfied with textiles when they are unsuitable for the season. Eco-friendly textiles were chosen for baby health and eco-friendliness, and respondents were satisfied with a baenaet jeogori made of eco-friendly textiles in general. The results show customers' high interest in textiles and the popularization of newborn clothing made of eco-friendly textiles. There was little interest in eco-friendly or safety certification marks despite the significant interest in the functionality and safety of textiles. Therefore, correct information on those certification marks is required.

  • Korean traditional mask play was done at outdoor to let spectators join the play and take mask at performance and to have disadvantage of poor transfer of dialog to the spectators. Performers transferred dialog directly and/or indirectly by using visual costume, and Tongyeong Ogwangdae with many dialogue expressions concerning the costume made use of proper intention to help spectators understand. In this study, the author watched performance of Tongyeong Ogwangdae to collect and investigate not only image material but also photograph material and to classify intention of the costume into three: First, contents of the dialog were intended to make shape. The costumes of Hongbaek Yangban, Meoktal Yangban and Jorijung of the 2nd section gave spectators contents of the play, and the costume of Halmi Yangban of Nochangtal of the 4th section described dialog of Halmi. Second, dialog had connotative metaphor. The costume of Yeongno of Yeongnotal of the 3rd section symbolized an unfinished dragon, while that of Halmi of Nongchangtal of the 4th section did sacred of Halmi. And, Nongchagtal Ai's costume of the 4th section prayed for value of Ai, richness of the life and fecundity. Third, conflict between characters was intended by indirect media. The costume of Maltukee of metaphor mask of the 2nd section became base of the assertion supporting that Maltukee had better birth history than Yangban had, and the costume of Yeongnoyangban of Yeongnotal of the 3rd section produced conflict at disclosure of identity.

  • This study identifies how the luxury brand marketing mix affects customer equity drivers and suggests intangible equity management strategies so that companies can make long-term profits through luxury brands based on empirical studies of Korean luxury consumers. The results of the study are as follows: First, this study classified the properties that use 8 key factors (product integrity, heritage, exclusivity, premium image, environment and consumption experience, premium price, luxury communication strategy, and brand signature). Second, it shows that product integrity and luxury communication strategy have a positive effect on all customer equity drivers, that brand signature has a positive effect on value equity and brand equity, and that premium price has a negative effect on relation equity. It is important to provide products and services equipped with high quality and luxurious designs based on excellent craftsmanship in order to establish brand equity and value equity. Brand identity needs to be maintained and unique brand signatures need to be developed based on the long history of luxury brands against a traditional backdrop. A diversified communication strategy improves brand recognition while playing a part in facilitating brand association and brand image. In order to improve relationship equity, actions such as a loyalty program to strengthen brand loyalty, need to be taken as well as measures to maintain and enhance customer trust through a reasonable price strategy.
