Jean-Charles de Castelbajac is gaining worldwide recognition as a designer who is not conscious of fashion and meet the desire of times. Castelbajac's works can be devided into three periods. 1. Creative challenge period. (1968~78) - His works started from creative challenge against haute-couture attract with practical design and extraordinary textile use. 2. Artistic development period. (1979~88) - He made unique ideas with the four primary colors affected by modern formative art. Pop-art clothes using cartoon or graffito were highlighted. 3. Aesthetic maturity period. (1989-now) - He received chevalier of Arts and the Letters at 1989. He was acquainted with other many designers in the world at 1990s, and his works came to mature. The aesthetic qualities in Castelbajac's works can be identified with the following themes. 1. Geometrical simplicity - Geometrical form without decoration and unnecessary lines used for the most comfortable cloth to wear and act gives an impression of explicitness and intelligence. 2. Humorous decoration - An unique idea having wit and humor shows his philosophy that must be new, vital and delightful. 3. Parody presentation - Pictures or people are reorganized 9Y work philosophy, then that get satirical and comic effects. 4. Pop-art image - Using mass communication media like a cartoon, figures, flag, graffiti, it produces clear and bright image.

This study presents a conductivity measurement technique that is applicable at radio frequencies (RF). Of particular interest is the measurement of the RF conductivity of a flexible Zell fabric, which is often used to implement wearable antennas on clothes. First, the transmission coefficient is measured using a planar microstrip ring resonator, where the ring is made of a Zell fabric. Then, the fabric's conductivity is determined by comparing the measured transmission coefficient to a set of simulation data. Specifically, a MATLAB-based root-searching algorithm is used to find the minimum of an error function composed of measured and simulation data. Several error functions have been tested, and the results showed that an error function employing only the magnitude of the transmission coefficient was the best for determining the conductivity. The effectiveness of this technique is verified by the measurement of a known copper foil before characterizing the Zell fabric. The conductivity of the Zell fabric at 2 GHz appears to be within the order of $10^4S/m$, which is lower than the DC conductivity of $5{\times}10^5S/m$.

To show the recognition of hand-sanitizer, we studied the answers of research questions where we got from the northern part of Seoul and Kyunggi Province. We had categorized two groups both industry-related people who work in restaurants, hygiene service shops, whole sales, government organizations, PC shops, factory-department stores and non industry-related people who work in schools, general offices for this study. 1. Hand sanitation level: Over 60% people washed hands 6 times a day. The group using water and soap was much bigger than the group using water for washing hands. For drying, people preferred wipe tissue, towels, clothes, non drying in that order. 2. Recognition of hand sanitizer and its usage experience: Most people(66.5%) did not know what hand sanitizer is, but they have positive attitude if they use this machine. 3. Place of hand sanitizer: The proper places to install were such public places as hospitals, restrooms, and restaurants. The fifties-group was the most frequently hand washing generation with over 9 times a day. 4. Comparison of recognition for hand-sanitizer by male and female: There were different results in each evaluation item by either male or female. The frequency and method of hand washing showed high in males, while females observed hand sanitization, installation requirements, installation areas, home installation, etc more than anything else.

This study aims at establishing a sizing system required for producing ready-made clothes which can fit the body shape of disabled men using wheelchair. It measured the bodies of 178 adult men using wheelchair and compared the sizing system of German adult men using wheelchair (1984) with KS system(KS K0050, 2004) in order to establish standards of the sizing system. AS a result, in terms of classification of body shapes, KS system cover more types of disabled men's body shapes and especially, A types (Drop 15.6) showed the widest coverage with 32%. In classification of heights, the widest range of height was 170 cm, and Korean men's four sizes between 158 cm and 176 cm covers 88.2% of disabled men's body shape. For chest size, 91.1% of disabled men's chest sizes were included in seven sizes, which are 4 cm intervals between 88 cm and 112 cm with 100 cm standard. In consideration of the ranges of height and chest, the general sizes (A types; 11 sizes, B types; 3 sizes, Y types; 5 sizes) are selected to present the standardized measurements. Basic parts of the upper garment sizing system for disabled men using wheelchair were height-chest-waist size.

What human beings wear is closely related to how they conceptualize their bodies and how they classify the group they belong to and the way they wear their cloth s an important cultural element that shows wearers' awareness and social relationship. Especially, underclothes reflect unrevealed cultural inside of the society more abundantly than outer wear do. Through such characteristics of underclothes, we are able to better understand inherent order of culture. This study si to understand the characteristics and changes of Korean culture by reviewing the convention of underclothes wearing that takes important role in clothing without being explicitly revealed. For this study, in addition to biblical review of under clothes of traditional societies, a total of 301 college students aging from 19 to 28, who are the most open to accepting new cultures and changes, residing in Seoul area were participant. Questionnaire consists of open-ended questions of underclothes terms, kinds, why they wear, items of wearing, how they obtained, how they take care of, etc. In conclusion, changes in cultural meaning of underclothes analyzed through convention of underclothes wearing are as follows; 1) changes in wearing pattern implies changes in functions of underclothes and changes in members' roles and values in a society; 2) changes in recognition of underclothes are related to the changes in awareness of sex; 3) consumer behaviour of underclothes represents a part of information culture; 4) changes in the pattern of maintaining underclothes show that differentiation of sex role in household tasks is decreased.

This Paper deals with the stochastic behavior and failure analysis of a Viscose Staple Fibre Plant which produces fibre for making clothes. The fibre making plant is a complex system with various subsystems as: Vendor (supplies Charcoal and Sulphur, raw materials for the process), Carbon di sulphide Plant, Acid Plant, Pulp Plant and Processing Plant. The considered system can completely fail due to failure of any of the subsystems. The Carbon di Sulphide Plant can fail in two different ways, due to lack of Sulphur or Charcoal. Processing Plant has the configuration 5-out-of-10: d and 6-out-of-10: f. It is also assumed that the system can fail due to workers strike and catastrophic failure. All failures follow exponential time distribution whereas all repairs follow general time distribution. Preventive Maintenance policy has been applied to reduce the failure in the system. Various reliability characteristics such as transition state probabilities, steady state behavior, reliability, availability, M.T.T.F and the cost analysis have been obtained using supplementary variable technique and Gumbel-Hougaard copula methodology.

According to flow of energy, the loss occurs through walls, roofs, windows and so on. Among these case, most of the loss that is about 45% occurs through windows. windows's U-value is six times higher than wall's one according to Building code, so the loss through windows accounts for very much rates. Currently, Exterior wall's U-value about building envelope is 0.35~0.58W/ mK, but windows's one is 3.3W/ mK. It means that the loss through windows occupy very much amounts relatively. Therefore, the solution is required to reduce energy loss and increasing displeasure caused by excessive influx of solar energy through windows, to solve the problems Like decoloration on indoor furniture an clothes by harmful ultraviolet rays, air conditioning and increased cost. Therefore, on this paper, Thermal Performance was evaluated through actual test about high insulation Super Window which can improve thermal performance and the Simulation result was compared with actual resul by using Simulation program WINDOW and THERM.

All the outdoor and indoor spaces are connected with each other. The human being moves toward those spaces and experiences temperature fluctuation between the natural and artificial temperature. We conducted an experiment which subjects are the college students wearing the data logger in urban life, and measured 24 hours' exposed temperature and thermal comfort in summer. Results were as follows. 1. Most subjects get weather information(84.6％). Fashion(46.2％) and weather (30.8％) are the reasons to select clothes. They spend their time in indoor environment for 84.92％ hours of a day and have an air-conditioner(61.5％) in their houses. 2. Exposed temperature fluctuation were from 33.8$^{\circ}C$ to 15.6$^{\circ}C$. The median value of experienced temperature were 26-27$^{\circ}C$ and average temperature was 26.3$^{\circ}C$. Subjects experienced cold shock of 3.96 times in a day and 67.21％ of all evaluated thermal comfort in the range of -1 and 1 by ASHRAE 7 Category Scales.

The previous study reported that the quaternary copolymer of MMA, BA, MAA, and NEA was expected to be a good monomer composition for a binder polymer with good rubbing fastness for digital textile printing(DTP) pigment ink. However, the rubbing fastness of the dyed fabric with the quaternary copolymer binder containing pigment ink is not enough to be commercially used. Therefore, this study aims to optimize MMA:BA:MAA:NEA composition for improved rubbing fastness. And the binder polymer with various MMA:BA:MAA:NEA compositions were synthesized using miniemulsion polymerization. The particle size, viscosity, molecular weight, and Tg of the synthesized binder were evaluated. And the color strength and rubbing fastness of the black pigment ink dyed cotton fabrics with the prepared binders were also evaluated. Then, the stiffness of undyed and dyed cotton fabrics were evaluated to investigate the changes in touch as the binder structure changes.
