To develop the work clothes for the employees in the mechatronics industry in South Korea, a questionnaire survey on many aspects of the work clothes such as type, color, detailed design and function preference of the subject employees has been carried out in the study. The results throughout the survey highlighted certain functions such as extensibility, thermal and air permeability of importance for the work clothing performance. To improve the discomfort caused by some work motions (i.e. squatting down, ascending/descending the stairs, raising arms), more allowances were given to the measurements (i.e. body rise + 2cm and crotch depth + 1cm for squatting down pose; thigh circumference + 1cm and knee circumference + 1cm for ascending/ descending the stairs pose; chest circumference + 5~6cm and jumper length to the level of hip circumference line for raising arms pose) for work clothes patternmaking. The evaluation of the two types of spring/summer and winter work clothes' clothing comfort and wearer mobility suggested certain points to improve the clothing performance (e.g. ventilation slits on the back pleats, arm pits and collar band of the spring/summer suit using net material and lining for the winter suit using quilted thermal materials) and wearer mobility (e.g. pants hem buckles for the easy work motion), which also enabled to fulfill the workers' work clothes design preference.

The purpose of this study was to investigate perception of risks among South Korean female college students within the process of purchasing apparel products through the Internet. The study was implemented by descriptive survey method using questionnaire and subjects consisted of 324 South Korean female college students. Findings of the study showed that the purchasing process particularly regarding delivery and security issues seemed to be a strong concern. On the other hand, unique selection such as apparel brands only available through the Internet was a strong appeal to 37.7% of subjects. Factor analysis profiled risk perception as: 1) Internet Shopping Selection Preference, 2) Delivery Problems and Lack of Security 3) Product Quality and Characteristics 4) Return Policy Difficulties and 5) Fair Prices. Discriminant analysis showed Factors 1, 2 and 3 were significant in helping to differentiate among Non-Purchasers, Fewer-purchasers and Many-Purchasers. Factor 1 and 3 helped differentiate among respondents relative to age range. Across all types of purchasers, offering unique selections of cutting edge fashions and improving risk perception relative to delivery and security concerns seemed important for gaining greater market share. Being able to delivery quality products and communicate product characteristics would be a powerful competitive edge to add to the incentive of convenience in shopping for apparel on the Internet.

The effect of coated polyester (PET) textiles with metal oxide, chitosan, and copper ion on the antibacterial and antiviral activities was evaluated to investigate the applicability of multi-coated PET textiles as antiviral materials. Compared to coated PETs with a single agent, multi-coated PETs reduced the loading amount of coating materials as well as the contact time with bacteria for a bacterial cell number of < 10 CFU/mL, which was not detectable with the naked eyes. Metal oxides generate reactive oxygen species (ROS) such as free radicals by a catalytic reaction, and copper ions can promote contact killing by the generation of ROS. Chitosan not only enhanced antibacterial activities due to amine groups, but enabled it to be a template to load copper ions. We observed that multi-coated PET textiles have both antibacterial activities for E. coli and S. aureus and antiviral efficiency of more than 99.9% for influenza A (H1N1) and SARS-CoV-2. The multi-coated PET textiles could also be prepared via a roll-to-roll coating process, which showed high antiviral efficacy, demonstrating its potential use in air filtration and antiviral products such as masks and personal protective equipment.

With entering the 21st century, modern people's dark inside and panic are emerging as the talking point on the theater stage. Even in the field of stage costume, the necessity of a research is being demanded through analyzing on psychological anguish and structure of characters. Accordingly, this study aims to allow the stage costume design to be expressed a human being's Doppelg$\ddot{a}$nger Image, which was elicited through analyzing a work of the play titled Le Grand C$\acute{e}$r$\acute{e}$monial by a playwriter Fernando Arrabal, who draws the conflictory and contradictory duplicity, which positions in a human being's deep inside by having chaos as catalyst. A research subject is 'Le Grand C$\acute{e}$r$\acute{e}$monial,' which was staged as the winter performance in commemoration of the 50th anniversary for the foundation of Dept. of Theater, Chung-Ang Univ. in November 2009. Psychology of characters in a play, which varies dimensionally, could be delivered, as nonverbal element called costume, by applying costume design of Cavanoza, Syl, Nice to Doppelg$\ddot{a}$nger Image such as Innocence vs Cruelty, Purity vs Superficiality and Restraint vs Freedom, which were elicited through analyzing characters. Through this study, the costume, which was expressed by visualizing a human being's Doppelg$\ddot{a}$nger Image, could be known to function as important dramatic factor of allowing character's psychology to be understood through costume as well as functioning as visual and sensible language, which is important for communication with the audience. A research on costume design, which reflects a character's complex inside, is expected to be likely continued through in-depth analysis on a playwriter's intention and on the appearing characters at the current point of time when an active research is being performed on stage costume in the wake of this study.

This study examines the effects of collaboration type and brand sensitivity on consumer responses toward fashion collaboration brands. For this study, six brands of fashion collaboration were selected by collaboration types: collaboration with same industry (Uniqlo-Jill Sander, H&M-Sonia Rykiel, and Levis-Jean Paul Gaultier) and collaboration with different industries (LG-Prada, Samsung-Armani, and LG-Levis). A selfadministered questionnaire was developed based on the literature that mainly included brand sensitivity, consumer response (brand association, brand values, and purchase intention), and marketing strategic elements in the context of fashion collaboration. For collecting the data, respondents were asked to choose and assess a previously purchased brand. A total of 299 usable data responses were obtained from Korean consumers aged from 15 to 40 years old. The consumer response toward the fashion collaboration brand consisted of four factors: Emotional value, perceived quality, symbolic value, and brand association. The results showed that the collaboration type had the main effect on emotional value, symbolic value, and purchase intention. Brand sensitivity had the main effect on brand association, emotional value, symbolic value, and purchase intention. There was also an interaction effect on emotional value. With respect to strategic marketing elements, product differentiation, premium pricing, and value pricing had partially positive effect on consumer responses; however, promotion had a negative effect on consumer responses (e.g., perceived quality, and emotional value). In addition, collaboration type or brand sensitivity moderated the effect of strategic marketing elements on consumer responses. This study discussed a managerial implication to develop a strategic brand alliance to manage brand equity in the fashion marketplace.

Ethnical tendency follows the current political, economical, and cultural influence eastwards, highlighting films, architecture and interiors as well as fashion. With this tendency, the ethnic outfits are expressed by various styles. This study analyzes the features of current ethnic styles with 1,535 ethnic image pieces from 2005 S/S to 2010 F/W of Pr${\^{e}}$t-${\'{a}}$-Porte in Paris and Milan. First, 'ethnic' is to refer to the distinct features of an ethnic group or a country. 'Ethnic look' refers to the adaptation or re-arrangement of various ethnic group's traditional costumes, dying, textile, patterns, color, silhouettes, and accessories. Second, the most popular ethnics in the modern fashion is the African style, followed by India, Japan, China, and Latin America in both collections. Third, the proportion of ethnics decreased, 2005 (14.9%), 2006 (12.8%) and 2007 (8.2%). In 2008 the proportion increased again. 2010 (27.3%) and compared 2010 to 2007, it increased by 20%. By season, S/S had 1.4 times more ethnic styles than F/W with the prevalence of African and Indian styles. Fourth, as of 2005, the ethnic style became colorful and went through changes to combine various images. This is from the polycentric tendency of co-existing various styles with a prevalence of low tone and various colors. It also shows warm colors in front to show a sense of nature.

Consumers nowadays spend more time using computers and are getting used to buying products through the Internet(Park, 2002), and therefore, understanding consumers' impulse buying behavior in an online shopping context is also important for retailers. The purpose of this study was to examine the relationship between online apparel impulse buying behavior and the two risk dimensions of apparel involvement(i.e., risk importance, risk probability). The data were collected using an online survey with a structured questionnaire. A total of 339 college students were used in the study. The results of MANOVA showed that the impulse buyer group perceived the risk importance and risk probability of apparel involvement significantly lower. Based on the results, the two hypotheses were supported. From the results of the present study, it is concluded that the two risk dimensions of apparel involvement are negatively related to online impulse buying behavior of apparel products. From the results of the present study, it is concluded that the risk dimensions of apparel involvement are closely related to the online apparel impulse buying behavior.

The effects of removal of lignin or hemicellulose on the cottonizing and pulping characteristics of kenaf fiber were studied by comparing the conditions of non-cellulosic material contents, fiber lengths and dyeability. And the effects of lignin or hemicellulose on dyeability of the kenaf fiber using CI Direct Green 26 and CI Direct Red 81 were investigated. The results were as follows. The lignin contents decreased and the kenaf fiber became shorter and finer as the reaction time with sodium chlorite increased. The hemicellulose could be removed by treating sodium hydroxide solution to the fiber from which the lignin partly removed. The 80% of hemicellulose could be removed by 5% of sodium hydroxide solution in 5 minutes. But if lignin were not removed at all, hemicellulose could not be removed. The fiber lengths proper for apparel were obtained after treating sodium chlorite for 10-20 minutes and those for pulping were obtained after treating sodium chlorite for 40 minutes. The kenaf fibers from which lignin and hemicellulose partly removed were dyed with CI Direct Green 26 and CI Direct Red 81. Their dyeability increased as the removal rates of lignin increased. The ${\Delta}E$ values of kenaf fiber dyed with CI Direct Green 26 were lower than CI Direct Red 81.
