Min Nyoung Seo , Young Seok Koo DOI: AbstractThe purpose of this study is to analyze the differences in color, pattern, and texture of functional materials of outdoor clothing according to new senior women``s psychological comfort. The data were collected from 163 female respondents aged 55-64 living in Busan. The results of the study are as follows. First, both the high and low psychological comfort groups preferred soft material the most. The high psychological comfort group particularly preferred soft textures and highly evaluated textured material in general. Second, both groups mostly preferred plain patterns while the high psychological comfort group preferred the dot pattern more. Third, in terms of colors, the high psychological comfort group preferred navy and purple, while the low psychological comfort group preferred brown. As to achromatic colors, both groups preferred black the most with the high psychological comfort group preferred gray and white more than the other group. Fourth, the high psychological comfort group preferred colors and patterns of clothing that made one look the most slimming, while the low psychological comfort group strongly preferred colors and patterns of clothes. Therefore, our results suggest that new senior women have a strong interest in outdoor clothing, not only in terms of textile functions, but also having interest in textile designs. In particular, the new silver women value psychological comfort in colors more than patterns of textile design.

TitleDevelopment of Ergonomic Leg Guard for Baseball Catchers through 3D Modeling and Printing
Hyojeong Lee , Ran-i Eom , Yejin Lee DOI: AbstractTo develop baseball catcher leg guards, 3-dimensional (3D) methodologies, which are 3D human body data, reverse engineering, modeling, and printing, optimized guard design for representative positions. Optimization was based on analysis of 3D body surface data and subjective evaluation using 3D printing products. Reverse engineering was used for analysis and modeling based on data in three postures: standing, 90° knee flexion, and 120° knee flexion. During knee flexion, vertical skin length increased, with the thigh and knee larger in anterior area compared to the horizontal dimension. Moreover, 120° knee flexion posture had a high radius of curvature in knee movement. Therefore, guard designs were based on increasing rates of skin deformation and numerical values of radius of curvature. Guards were designed with 3-part zoning at the thigh, knee, and shin. Guards 1 and 2 had thigh and knee boundaries allowing vertical skin length deformation because the shape of thigh and knee significantly affects to its performance. Guard 2 was designed with a narrower thigh and wider knee area than guard 1. The guards were manufactured as full-scale products on a 3D printer. Both guards fit better in sitting than standing position, and guard 2 received better evaluations than guard 1. Additional modifications were made and an optimized version (guard 3) was tested. Guard 3 showed the best fit. A design approach based on 3D data effectively determines best fitting leg guards, and 3D printing technology can customize guard design through immediate feedback from a customer.

Title3D Modeling of a Fabric based on its 3D Microstructure Image and Application of the Model of the Numerical Simulation of Heat Transfer
Hyojeong Lee , Heeran Lee , Ran-i Eom , Yejin Lee DOI: AbstractThe objective of this study was to perform 3D solid modeling from 3D scanned surface images of cotton and silk in order to calculate the thermal heat transfer responses using numerical simulations. Continuing from the previous methodology, which provided 3D surface data for a fabric through optical measurements of the fabric microstructure, a simplified 3D solid model, containing a defined unit cell, pattern unit and fabric structure, was prepared. The loft method was used for 3D solid-model generation, and heat transfer calculations, made for the fabric, were then carried out using the 3D solid model. As a result, comprehensive protocols for 3D solid-model generation were established based on the optical measurements of real fabric samples. This method provides an effective means of using 3D information for building 3D models of actual fabrics and applying the model in numerical simulations. The developed process can be used as the basis for other analogous research areas to investigate the physical characteristics of any fabrics.

TitleJersey Design and Pattern Making for Disable Players of Ice Sledge Hockey
Sanghee Park , Sungheum Um , Jinhee Park DOI: AbstractAs the quality of life has improved with development of science and technology, desire for better quality of life of disable people has also increased. Currently, prejudiced views of disabled people in South Korea are changing, but sports for all disabled people is not revitalized and social support is also inadequate. In developed countries, administration and systems for sports among people with disabilities are provided at the consumer level, and many companies willingly provide support to disabled athletes. However, in South Korea, low awareness of sports for disabled people is companied by minimal support companies. In order for South Korea to advance, support for the disable sports players is needed, especially sports-wear that fits their body conditions and differences game playing from ordinary sports players. This study specifically focused on the ice sledge hockey players, taking into account the complaints on their jersey and their special conditions through motion analysis while sleds. For the easy use of the hockey, armhole depth and sleeve breadth was reduced and sleeve hem was designed for flexibility of sleeve such that it does not slide down. Also, because only the front of the Jersey is tucked in the pants, the side vent was designed to be deep such that the back hem is prevented from being pulled. Sportswear pattern making for the players with disabilities required to account for distinct body characteristics, as compared to the ordinary players. Thus, studies that develops sports-wear design for those with disabilities contributes to the qualitative development of sports for people with disabilities.

TitleNew Seniors` Information Sources, Store Selection Criteria, and Sales Associates` Attributes for Clothing: Based on Their Clothing Involvement
Jeong-hyun Ghal , Miyoung Lee DOI: AbstractThis study examines female new seniors’ clothing consumption behaviors, such as their information sources, clothing store selection criteria, and perceived importance of sales associates’ attributes, based on their level of clothing involvement. A face-to-face survey was conducted through a market research firm. The subjects of this study were female adults in their 50s and 60s residing in the Seoul metro area (N=197). Significant differences were found in the clothing consuming behaviors of new seniors depending on their clothing involvement(CI). High-CI new seniors tended to place more importance on both personal and non-personal information sources than low-CI new seniors. High-CI new seniors place importance both "merchandise assortment and store atmosphere" and "sales associates and service" when they select stores for clothing than low-CI new seniors. In terms of sales associates’ attributes, high-CI new seniors tend to place more importance on customer-orientation than medium- and low-CI groups. Medium- and high-CI new seniors tend to place more importance on appearance than low-CI groups. However, there were no significant statistical differences for professional expertise among the three different CI groups.

TitleProduct-Story Congruence and Actor Attractiveness in Product Placements in Television Drama
Minhye Cheon , Yena Ahn , Ju Hee Mo , Jee-sun Park DOI: AbstractAs more consumers avoid ads aided by advanced technologies that conveniently block ads, traditional advertising is becoming less effective than ever before. Product placements are increasingly executed to unobtrusively expose products and brands to consumers while they watch media programs. The current study attempts to enhance our understanding of the factors that affect consumer attitude towards the brands placed in TV dramas. In particular, this study examines whether the attractiveness of actors and the congruency between the products placed and the story of the TV drama influence consumer attitudes towards the TV drama and the brand. A total of 211 male consumers in their 20s and 30s were used for data analyses. Structural equation modelling revealed that the product-story congruence had a positive impact on consumer attitude towards the TV drama as well as their attitude towards the brand. Actor attractiveness (in terms of similarity and likability) positively influenced consumer attitude towards the brand. Only the perceived likability dimension of actor attractiveness was found to affect consumer attitude towards the TV drama.

TitleA Study on the Properties of Silk and Nylon 6 Fabrics by Tannic Acid Treatment
Soojin Yoa , Jongjun Kim DOI: AbstractWeighting of silk fabrics have long been practiced in silk fabric trading based on the primary consideration of price-weight, and secondary one of quality improvement in handle, luster, and drape properties. Recent trend of practicing weighting of silk fabrics is, however, focused on the improvement of the handle, luster, drape, andother properties. During the finishing processes of synthetic fiber, nylon, comprising amide structure, include the use of tannic acid, especially in the dyeing. A multitude of studies are being implemented in terms of improving fastness to washing, fastness to light of dyed nylon product, or the light fastness of nylon 6 itself. In this study, the effects of various tannic acid treatments on the physical properties related to the handle of nylon 6 and silk fabrics are examined and reviewed. The effects of treatment condition of the tannic acid, e.g., the concentration of the aqueous tannic acid solution, treatment time, and temperature were investigated. As the concentration of the aqueous solution of tannic acid increased, the bending rigidity values of the silk and nylon 6 fabrics increased. The treated fabrics felt stiff to the touch. Within the mild conditions of bending employed in the bending measurement of KES, nylon 6 treated fabric specimen exhibited a trend of improvement of bending resiliency within the range of small bending deformation. The weight of treated fabrics have all increased. The air-permeability values decreased as the treatment concentration increased. However, the decrease tendency of air permeability values may be alleviated by adjusting the fabric count during the tentering or expanding processes, either by tension adjustment or heat treatment. Optimum conditions of the treatment for nylon 6 are 1.25% tannic acid concentration, bath temperature of 85 , pH 3.1, ℃ and those for silk fabric treatment are 1.25% tannic acid concentration, bath temperature of 85℃, pH 3.1. The treatment conditions will lead to the improvement in the properties of fabrics for summer. Key Wordssilk, nylon, tannic acid, bending stiffness, weighting |
