As the interest in leisure and health increases, the domestic outdoor wear industry becomes bigger. The waterproofness of fabrics does not ensure the waterproofness of garments because of the stitch holes during the sewing process even with the seam sealing tapes. Thus the water leakage often becomes a problem during the end use. Still companies use fabrics waterproofness data for garments marketing because they are simple to run the test, less expensive than the whole garment testing, and easy to achieve the quality control. In this study the rain tower system for evaluating the waterproofness of garments has been developed and the waterproofness of the selected waterproof and breathable garments in the market were tested. The rain tower was consisted of rain tower room, rainfall forming system and measurement system. Two different levels of rainfall can be simulated with this system(100l/m²/hr and 450l/m²/hr). Jackets in the market have been tested at two different rainfall conditions. The temperature and humidity data inside jackets didn't provide much information on the waterproofness at severe rainfall condition(450l/m²/hr, 1 hour). However, water leakage was detected on the cotton undershirt inside jacket. 5 out of 8 jackets passed the normal rainfall condition(100l/m²/hr, 30 minutes). The newly developed rain tower system was able to evaluate the waterproofness of the jacket seams. It is recommended the further study on the detailed test conditions for the end use of the waterproof and breathable garments.

In case of pure rubber materials, the initial quality of the rubber materials would be excellent, however, the durability against external impact might be poor. In order to overcome the relatively low durability, textile cord could be employed with silicone rubber. We have studied the improvement of heat-resistant adhesion properties of silicone adhesives between silicone rubber and PET fibers by applying various conditions including dip solution recipe. The silicone rubber used was a platinum catalyst curing type and platinum catalyst type silicone adhesive was used as an adhesive to obtain an optimum adhesive force. Furthermore, the bonding mechanism between silicone and PET fiber was established.

The men's costume of eighteenth century showed feminine image of elegant decoration through the influence of social feminine atmosphere. As years go, heading towards the end of the eighteenth century, most of men's wear were simplified except vest, which had gorgeous decorations showing feminity. Therefore, men's vest of eighteenth was regarded as good item to apply to modern women's wear. The men's vest design of eighteenth century were divided into three types due to the passage of time, they showed the difference in the length, detail and trimming. Cutting lines in the modern fashion are used to give comfort and show the three-dimensional body silhouette. Also, cutting lines, as a decoration element, can define the costume's image and characteristics. Therefore, by using cutting lines, we can represent historical costume as modern costume and men's wear as women's wear. I made five women's costumes applying design characteristics of the men's vest of the eighteenth century. These five women's costumes have decorative aspect of men's vest of eighteenth century and simple aspect of men's costume. I applied dart manipulation in several different ways to make various cutting lines for women's costume. These cutting lines were emphasized by matching various colors and patterns of fabrics. I made small buttons and cords of these various fabrics. I sewed fabric buttons on five costumes for the purpose of function and decoration like buttons of the men's vest of eighteenth century. I applied fabric cords to decorate five costumes in various way. We should further study how to express important characteristics of historical costumes as modern costume in many ways.

Recent economic depression aggravates the difficulty in employment, and it has been expanded to a social issue. Even worse, low wage structure in the textile and fashion industry, and inferior working environment make it difficult for fashion design graduates to stably settle down in society. To tackle all these problems, the demand of a new educational model is on the rise. In responding to such economic and educational environment changes, we can actively cope with structural problems in the textile and fashion field, and a social problem of youth unemployment by vigorously using the Internet as a tool for practice. In other words, Startups are reinvigorated through hands-on education, focused on information by introducing the factor of supply chain management (SCM), which efficiently manages resources within the supply chain, and a business to customer (B2C) model, and by utilizing these for startup education.

This study deals with antibacterial properties of nylon fiber treated with glycidyltrimethylammonium chloride(GTAC) and silver nanoparticles(AgNPs). Nylon fibers were soaked into GTAC(2-30%, v:v) solution for 20 min. After sample was pre-drying at $80^{\circ}C$ for 10min and cured at $180^{\circ}C$ for 5min. The AgNPs coating was accomplished by soaking in silver colloid solution at $45^{\circ}C$ for 90min. The coated nylon fibers were characterized by scanning electron microscopy-energy dispersive spectroscopy(SEM-EDS). EDS analysis indicated that AgNPs and GTAC was attached on nylon fibers. The treated nylon fibers showed antimicrobial properties against Escherichia coli(ATCC 43895), Pseudomonas aeruginosa(ATCC 13388) and Staphylococcus aureus(ATCCBAA-1707).

This study was conducted to find out the purchasing characteristics, the wearing practices and the preferring style of skirts. Also the comparison between recognized body type and actual body type for skirt was analyzed. The questionnaire was developed and administered to 179 women aged 20 to 59 in Busan. The women of 20th liked to buy skirts at the road shops and the internet shops but the 30th, 40th and 50th at the department stores and the discount stores. The main purpose of buying skirts was to coordinate with other clothes. The design of skirt was the most important factor of buying. The women of the 20th wore skirts without special purpose but the 30th, 40th and 50th wore those for social life. The women of the 20th liked to wear skirts with t-shirts and cardigan, the 30th with blouse and cardigan and 40~50th with blouse and jacket. As the age increased, the ratio of women who felt discomfort of skirts increased. Most of these women felt discomforts in the waist and abdomen part of skirt. The style of skirt that made up for the weak points in the body type was preferred. The preferred silhouettes of skirts were semi-tight and A-line. The preferred lengths of skirts were different from ages. Black was preferred color of skirts. There was a significant difference in recognized body type according to age groups. As the age increased, the ratio of women who thought themselves as thick waist type increased. Just only 43% women of total subjects recognized their body type accurately.

The purpose of this study is to examine the evolution of precious metal and gem stores, and to derive the characteristics of this period from the government, industry, and consumers. Correspondingly, the contents of daily newspaper articles during this period were analyzed using Naver's news library search engine. The historical development process is as follows. Before the Korean War, precious metal jewelers operated in Jongno, Namdaemun, and Chungmuro, dealing with gold, silver, and platinum. Large stores not only sold jewelry and watches, but also functioned as craftsmen and watch repairers. After the war, a shopping district for precious metals and jewelry was formed around Midopa Department Store. By 1963, the number of jewelry stores in Seoul increased to about 130 and to about 280 by 1966. The characteristics of the government, industry, and consumers are as follows. The government continued to implement a policy to regulate the precious metal and jewelry industry. Despite challenges, the industry exhibited the potential for foreign currency acquisition and growth through domestic amethyst. Consumers could access information regarding precious metal jewelry in daily newspapers. In the late 1960s, various types of jewelry were distributed in line with an increase in income levels.

With the development of information and communication technology, interest in new educational approaches that can enhance the learning performance of learners with improved information literacy skills is increasing, and universities are actively promoting educational innovation to foster the talents required by society. In the field of fashion studies education, which is closely related to the fashion industry, there is a strong need to develop field-linked educational programs that reflect the trends in the industry and changes in the educational system. The purpose of this study was to introduce industry-coupled problem-based learning (IC-PBL) to the course "Understanding Fashion Consumption Trends" for non-fashion majors to reflect the current needs and strengthen the educational effectiveness of the learners through a survey. A seven-step curriculum (introduction to the class, practitioner's problem, learner's problem analysis, organizing concepts related to variables, information collection and scenario writing, presentation and scenario proposal, and evaluation) not only enhanced learners' understanding of fashion consumption trends and the fashion industry but also greatly amplified learners' satisfaction with the class. The results of the survey showed that the seven-step curriculum was effective in increasing learners' self-directed learning ability, problem-solving ability, and confidence in learning. Self-directed learning ability was stronger than other factors, consistent with the core principle of problem-based learning to empower learners to take the initiative and promote self-directed learning. Each factor analyzed was positively correlated.
