This study researched the status and prospect of a natural dye program in Gyeongsang region that focused on private centers with sufficient infrastructure and abundant human resources were available for natural dyes. The entire site for metropolitan cities that have difficulty in securing the land are limited (as well as smaller) because they are closer to the city; in addition, they do not own the drying house and the agricultural land for natural dyes. It is understood that the one-time program of all centers researched help to promote and maintain the centers rather than generating profit; in addition, it is shown that Jun - Aug (summer) is preferred over Dec - Feb (winter). This program uses natural indigo; consequently, natural dye program for hobby and education is operated when it is required because the number of participants are low in most cases, Persimmon Juice is used for the dyeing raw materials. Programs in operation are often outsourced with other institutes registered under private certification system; therefore, many cases of starting business are found in the institutes operating programs directly after obtaining the certification. Their plans do not allow for investment in facility such as enlargement of experience center and prospect of program; in addition, business value is generally bright for business strategies that include an exhibition shop for natural dye products and program development.

In this study, the dyeing conditions(temperature, time, concentration) are changed from various conditions on wool fabrics by using corydalis tuber extract in order to develop new natural dyes. The purpose of this study is to improve the dyeability, color fastness, and functionality and to derive optimal dyeing conditions by comparing and analyzing the changes of K/S values and surface color by dyeing pH changes, mordant method, and mordant type. As a result of the experiment, the optimum dyeing condition of the wool fabrics is shown dyeing temperature:$80^{\circ}C$, dyeing time:90min, dyeing concentration:100%. The dyeability by pH variants of corydalis tuber extract indicates that K/S values is higher alkaline than acidic. The mordant method of corydalis tuber extract showed pre-mordant has high K/S values. In terms of color fastness, marked improvement has not been shown despite of mordant treatment on wool fabrics. In particular, color change of color fastness to washing, color fastness to light indicates the low fastness. In addition, the functionality such as antibacterial activities and deodorization can be given at dyeing with corydalis tuber extract thus it is expected to be applied to underwear or apparel products for the elderly and infirm and children with weak skin that required high functionality.

This study aims at developing ergonomics patterns for the sleeve of structural firefighting protective clothing through 3D motion analysis in order to ensure efficiency and safety of firefighters who are exposed to harmful environment at work. A new research pattern was developed by applying the total results of 3D motion analysis, changes of body surface length measurements, and 2D data on 3D body shape analysis on the size 3 patterns of the existing coat sleeve. For the sleeves, we used the body surface length of the range of shoulder's flexion and the joint angle of the range of wrist's ulnar deviation. And for the production of structural firefighting protective clothing using the research pattern, we recruited a recognized producer of structural firefighting protective clothing designated by KFI. Unlike everyday clothes, structural firefighting protective clothing should be able to fully protect the wearers from the harmful environment that threatens their lives and should not cause any restrictions on their movement. Therefore, the focus of research and development of such protective clothing should be placed on consistent development of new technologies and production methods that will provide protection and comfort for the wearer rather than production cost reduction or operational efficiency. This study is meaningful as it applied 3D motion analysis instead of the existing methods to develop the patterns. In particular, since 3D motion analysis enables the measurement of the range of motion, there should be continuous research on the development of ergonomics patterns that consider workers' range of motion.

This study proposed a revision of standard sizing system for infant clothing to provide exact information for consumers and manufacturers. The size designation was set up by compensating the defect of existing system. Basic body measurement and reference body measurement were analysed according to size designation. The ages of the infants ranged from 0 to 36 month in accordance with safety standard of KC Self-Regularity Safety Confirmation. The results are as follows: Size designation for infant clothing was based on height that was basic body measurement. Chest girth, waist girth, head girth, arm length, foot length and weight were also analysed according to age of the month. It was proposed that height could be written alone and height with age of month did together for size designation. Size intervals of basic and reference body measurements were fixed as follows: size intervals are 5 cm in height, 2 cm in chest girth, 2 cm in waist girth, 1 cm in head girth, 2 cm in arm length, 0.5 cm in foot length and 2 kg in weight. The distributions of height and chest girth showed normal distributions. As height was taller, chest girth was also bigger. But the distribution of waist girth didn't show remarkable change with age of month. The distributions of arm length and weight showed remarkable difference with growth in 0~9 months, but the amount of growth variation got less in 12~18 months.

This study considers application types and meanings of fashion engineering by analyzing CuteCircuit. The conclusions of this study are as follows. The application type of fashion engineering shown in CuteCircuit is first, electronic fashion, which attaches LED or WL on the surface of clothes to express the decorative function in clothes as optical light change, ultimately performing one-dimensional function. Second, interactive fashion is a medium in which clothing connects human beings with other human beings with sensors that can recognize the changes in tactile or movement with the wearer or with a light source that can visualize the emotional changes of the wearer. Third, scientific fashion has emerged as a new type of fashion in which new materials introduced in the field of engineering are fused with clothing to expand functionality and aesthetics. The meanings of fashion engineering in CuteCircuit is first, trying to conceptualize a new beauty as an open fashion that can freely change with the creation of a dual beauty by combining analog and digital sensibility. Second is the external representation of human psychological change or emotional exchange, which helps to form a consensus by understanding and exchanging emotions of different people. Third, reorganization of apparel pursuing integrated value appeared. Clothing, as a connection body in which the human body and the mechanical environment are combined with each other, is reestablished as a product of variable body that can embody an integrated value that includes various characteristics and can be diversified appropriately in any circumstance.

This study aims to discuss what changes Korean clothing companies and manufacturers have undergone with production facilities moving abroad due to offshore outsourcing and examine what conditions the clothing manufacturers are facing and how the clothing companies recognize those manufacturers. For these purposes, in-depth interviews were conducted with 24 firms with annual production capacity of more than 200,000 pieces among clothing brands for the domestic market, clothing exporters and promotion agencies. Those interviewed firms were the companies who were found to produce more than 200,000 pieces of clothing per year, and the interview-based survey was conducted from December 18, 2008 to January 30, 2009. The key findings from this study are as follows; first, a high percentage of interviewed firms were producing only a small number of items in Korea with a large part of their production line transferred abroad or outsourcing all of their production abroad only with their headquarters in Korea. Second, many were employing contractors rather than their own factories. Third, when asked about the wage levels of clothing manufacturers, many of the clothing companies gave responses such as: 'They are just our contractor, so we respect their decision,' 'We don't know because it's none of our business,' or 'We don't know at all.' Fourth, when asked about the work environment of clothing manufacturers, the clothing companies gave responses such as: 'We know in part,' 'To our knowledge, they conform to the Labor Standards Law,' or 'We don't know at all.' Fifth, the production line of clothing manufacturers featured straight-line systems, specialization, pairing and compounding/mixing. Sixth, it was found that clothing companies had interest in mass customization but their preparations were not satisfactory.

Packaging of shopping bag is a 'silent salesman' which plays an important role in marketing communication due to the increase of self-service outlets and changing lifestyles of customers. Retail shopping bags, which are defined as bags provided by retailers to customer as a means of transporting merchandise, are a type of secondary packaging. This study explored the effect of a fashion product's shopping bag types in sense of shopping value, customers' response, attitude toward advertising, and purchase intention. Data was analyzed by factor analysis, frequency analysis, correlation, structural equation modeling using SPSS 18.0 and AMOS 18.0. The results of this study were as follows. Consumers' responses about shopping bags show that there are some differences between consumers who have either hedonic or utilitarian shopping value. Hedonic shopping value influences on consumers' response as unique, interesting, and attention; however utilitarian value affects prestige in addition to those four significant factors. Therefore, this study shows that consumer response is different in accordance with shopping value. Thus, using the various types of shopping bags can be influenced on effective advertising. It will also great effect on marketing activity with lower cost. The significant result from this study has proven that the shopping bag is correlates to the definition of pop art today because it can offer an opportunity to look at, play with and buy sophisticated visual stimulus. Therefore, retail and brands have to concern about shopping bag considering their decisive role in the apparel market.

This study was conducted to find out the relationship between skin temperature and clothing temperature in body parts. Four different kinds of fabrics were used in this experiment. These fabrics were a (Ny/Spun, 81.8/18.2%), b (Wool/Poly/span, 50/45/5%), (Wool/Ny/Span70/25/5) and d (Wool/Poly/Span 45/45/10%). The subjects skated at indoor ice rink where the length was 111.12 m, the temperature was $11{\pm}1^{\circ}C$ and the humidity was $70{\pm}10%$. The four an male professional skaters speed was $17{\pm}1$ seclm/lap. Physiological parameters were skin temperature at 4 body points (chest, upper arm, thigh, leg) and clothing temperature at chest was measured every 15 second. Experiment protocol was as follows: resting before skating (5 min.), skating (5 min.), and resting after skating (10 min.). The results were as follows; The mean skin temperature by fabrics shows b > a > d > c. The mean skin temperature began to decline little by little as soon as the subjects entered the indoor ice rink. After they rested for five minutes, they started skating and the mean skin temperature declined widely. After skating, the mean skin temperature increased step by step. It maintained the similar temperature. The value of skin temperature at body points shows Leg > Chest > Upper arm > Thigh. Because of the characteristics of skating uniforms, the skin temperature of the leg is the highest. The skating uniform was designed to have a protective portion in the leg. The chest produces the highest temperature in the body. The comparison of difference values in skin temperature show Thigh > Upper arm > Chest > Leg. While skating in a cold atmosphere, the largest difference value is clothing temperature. The clothing temperature is lower than the skin temperature during skating. The difference value of clothing temperature is larger than the skin temperature of the chest.

This study aims to suggest practical considerations for designing protective clothing with increased visibility that will have higher user acceptance by law enforcement officers. Light-emitting diode(LED) patrol vests were visually and structurally assessed, and 125 police officers' responses from surveys about user acceptance of the vest were analyzed. The current LED patrol vest was designed for enhanced safety of police officers by increasing visibility in the dark. However, the user acceptance rate of the LED patrol vest indicates low use of and low satisfaction with the vest despite its enhanced safety features. In particular, differences in materials, design, functionality of the pockets and size of the vest depending on the hours worked, were statistically significant. The police officers' responses suggest areas of improvement in design, materials, ease of movement, size and functionality. Key issues include 'tactile discomfort'; 'impeded vision from the glare of the LED'; 'frequent malfunctions of the LED'; 'impossible repair of the broken LED units'; 'no user feedback'; 'inconvenient to replace batteries'; 'brittle materials' and 'unpleasing look'. To increase user acceptance, designer should incorporate context-awareness, a convenient user interface, a modular design approach, first responders' self-image as public servants in relation to their aesthetic perspectives of their uniforms, and scientific evaluation of the effectiveness of the intended functions of the clothing. Suggested implications for designing the LED patrol vest can be applied to designing other functional/protective clothing for intended end users with special needs.

This study aims to propose various ways to utilize CLO, which focuses mainly on the production of 3D virtual samples, by comparing it with the pattern drafting functions of Four apparel CAD experts, who have teaching experience in YUKA and CLO, participated in a focus group interview, and a basic bodice prototype drafting was carried out by each participant to evaluate the pattern drafting functions of YUKA and CLO. The result of this study showed that the pattern drafting tools of YUKA are subdivided since YUKA is a CAD tool inherently specialized in pattern making. Though CLO provided a relatively limited pattern drafting menu compared to YUKA, it was found that pattern drafting could be accomplished with the help of supplementary tools and functions. This finding suggests that each CAD offers the corresponding tools for the same use of menus or functions in the prototype drafting process. The major difference between YUKA and CLO is that YUKA defines the pattern area by a set of line segments, whereas CLO utilizes an outline composed of closed curves. YUKA provides various specific tools according to the options such as angles, straight lines, and curves, while CLO produces the same results using combinations of a limited number of tools. Compared with YUKA, the advantage of CLO is its user-friendly task environment such as the Windows-based user interface, from the usability perspective. This study concludes that pattern drafting education using CLO would help not only industrial 3D design practitioners but also pattern education in academia
