This study was designed to collect a precise information concerning to the preference and evaluations after usage of pregnant Korean woman for the maternity wear bysurvey and wear tests. Through the survey, 212 respondents were asked to answer what type of maternity wear they prefer and what requirements for maternity wear design are important. According to the results of survey, the mostly preferred maternity wear items were pants and one-piece dress. Korean customers for maternity wear usually pay more for the one-piece dress than other items and they also usually put on medium price pants and low-price blouse. Concerning to the purchase criteria, it may be said that design and movability, fit factors are the buying decision criteria of great weight for Korean pregnant women. Special function most desired was thermal insulation, followed by buffer action, electromagnetic shield and quickly water-absorbent and dry property. Preferred maternity wear design details were flat collar, slightly fitted waist and empire style, gather skirt, rubber band waist. Wear test was performed for two kinds of blouse (BL) and one-piece dress (OP), and threekinds of pants (PT), which have different design details respectively. According to the wear test for ready-to-wear maternity garments, the garment which considers well the characteristics of Korean pregnant women body shape earned much higher score no matter of brands or prices. Generally, high-priced national brands received an excellent evaluation in design aspect, but not satisfied with comfort to move.
The purpose of this study was to investigate the changes in the flexicurve kyphosis index (KI), the flexicurve lordosis index (LI) and the distance from the inferior angle of the scapula to the nearest vertebral spinous process (DS), as a dependent variable of scapular protraction, after applying of adolescents with thoracic hyperkyphosis using three different garments. A repeated measures design was used. Ten adolescents ($15.8{\pm}1.0$ years) with thoracic hyperkyphosis ($40.1{\pm}3.7$ Cobb angle) were recruited from a university hospital. A flexicurve ruler was used to measure KI and LI and a scoliometer was used to measure DS under three different conditions: wearing-a hospital garment (HG), wearing-a sham garment (SG), and wearing-an experimental garment (EG). KI under EG condition was significantly decreased compared with that wearing the HG. However, there was no significant difference between wearing the SG and HG. LI when wearing the EG was significantly increased compared with that when wearing HG. However, there was no significant difference under SG and HG conditions. DS when wearing the EG was significantly decreased compared with wearing HG. However, there was no significant difference between the SG and HG. The results of this study show that the EG was effective in decreasing KI, but not effective in decreasing LI. Hence, the effect of the EG for correcting sagittal spine angle in adolescents with thoracic hyperkyphosis is still debatable. However, since we showed that DS decreases in the EG, this method could be applied in correcting the scapular protraction.

While the conventional personal protective equipments (PPEs) covers a variety of devices and garments such as respirators, turnout gear, gloves, blankets and gas masks, several electronic devices such as personal alert safety system (PASS) and heads-up displays in the facepiece have become a part of firefighters personal protective equipments through past several years. Furthermore, more advanced electronic sensors including location traking sensor, thermal imaging caerma, toxic gas detectors, and even physiological monitoring sensors are being integrated into ensemble elements for better protection of firefighters from fire sites. Despite any electronic equipment placed on the firefighter must withstand environmental extremes and continue to properly function under any thermal conditions that firefighters routinely face, there are no specific criteria for these electronics to define functionability of these devices under given thermal conditions. Although manufacturers provide the specifications and performance guidelines for their products, their operation guidelines hardly match the real thermal conditions. Present study overviews firefighter's fatalities and thermal conditions that firefighters and their equipments face. Lastly, thermal packaging methods that we have developed and tested are introduced.

The aim of the present stud)r has been to obtain new and additional data allolwing a better design of sports garments as well as a better choice among some materiales, through measure-ment of body surface changes in the upper trunk in movement, measurement on the effects of local heating on other parts of the body and measurement of the thermal resistance of 6 types of materials applied on a manikin. In the first experiment, the upper trunk was divided in 32 Parts, the surface of which was measured by the tape method for two upper limb positions: extension at $90^{\circ}$ and $180^{\circ}$. In the second experiment, skin temperature, local thermal sensations and whole body thermal sensation were measured every 5 minutes during 40 minutes. The four areas of the shoulder, abdomen, hande and feet were heated with the hot pack at $50^{\circ}C$. In the third experiment, the regional thermal resistance of the various materials selected, in two different cases of clothing ease, have been measured by using a thermal manikin. Resultes of experiments were: 1. Extensions cause the upper front part of the trunk surface to lengthen vertically while the back tends to stretch in width. 2. Skin temperatures of the upper limbs are influenced by the abdomen and shoulder boatings. The correlation between the whole body thermal sensation and the upper trunk thermal sensation is significantly asserted. 3. Ceramic and aluminium coated materiales offer the most effective thermal resistance; ease in clothing increases the thermal resistance at the breast and the abdomen as well as the clo value of the materials.

This study investigated the clothing easiness of movement when wearing casual Hanbok(Saenghwal Hanbok), as a high school student uniform, and produced some recommendations for improving the Hanbok. Casual summer-uniform Hanbok produced from different types of materials were produced for this study. They were P/R, P100, P/C, and P/R/S for the blouses, with P/W, P100, P/R, and P/W/F for the skirts. Their clothing easiness of movement were then tested at $25{\pm}1^{\circ}C$ and $50{\pm}10%$ R. H. The results were as follows: The easiness of movement for casual Hanbok was marked as $3.7l({\pm}1.03)$ on average which is higher than those of other garments, so it can be presumed that the easiness of movement for the tested clothes was quite good. The easiness of movement was lower, however, when students had their arms up front, right arms upright, arms crossed on the cheats, and bent forward whereas they were more comfortable when standing straight and sitting on a chair at 90 degrees. In terms of easiness of movement, the following ranking was revealed: waist, bust, shoulder, back, armhole, and upper arm. The easiness of movement for casual Hanbok skirts was quite good, and on average marked around $4.26({\pm}.77)$. Standing straight was the most comfortable position, when they bend forward 45 degree and 90 degree were the most uncomfortable positions. The buttocks area was also more comfortable than the waist area for casual Hanbok skirts.

This study proposes the suggested amount of clothing (SAC) and examines the preferred amount of clothing (PAC) for thermal comfort in mild cold conditions. Six male and nine female college students were systematically exposed to mild cold conditions by reducing the amount of clothing (Step I, 1.2clo ${\rightarrow}$ Step II, 1.0clo ${\rightarrow}$ Step III, 0.8clo ${\rightarrow}$ Step IV, 0.7clo). The subjects were then asked to adjust the amount of clothing to attain overall thermal comfort until they maintained thermal comfort for 10 minutes without changing the amount of clothing (Step V). The experiment was carried out in a climatic chamber at $19.5^{\circ}C$, 50%R.H. Body composition was measured and individual cold climate adaptability was surveyed before starting the experiment. Rectal temperature ($T^{re}$), skin temperature ($T_{sk}$), and oxygen consumption ($\dot{V}O_2$) were measured and the overall thermal sensation was voted in each step. PAC was obtained from the garments weight selected by each subject in Step V. SAC was proposed based on the change of oxygen consumption (${\Delta}\dot{V}O_2$). As a result, males showed higher $\bar{T}_{sk}$ and greater $O_2$ than females (p<.01). SAC obtained from $\dot{V}O_2$ were 652.0 (SE 3.9) g/$m^2$ for males and 766.0 (SE 2.5) g/$m^2$ for females and it was significantly different between groups (p<.01). PAC of males and females were 1.6 and 1.5 times heavier than SAC. In conclusion, females were more sensitive to the cold stress and recommended larger amount of clothing than males.

Nowadays the numbers of the disabled and elderly have been increasing, and the development of adaptive clothing for these people is in demand. The purpose of this study was to give ideas and solutions for the special needs clothing design. The knowledge of medical situation of the individuals with special needs has been examined and factors affecting adaptive clothing were suggested. Twenty-one web sites were investigated and the most practical, functional, fashionable adaptive clothes were suggested by items. Construction and location of openings, number and type of fastenings, and design of garments for comfort and ease of movement were carefully considered in these clothes. Better appearance through improvement of clothing will help these people to believe that they have worth in the sight of others and in their own view of themselves. Disabled and elderly can obtain the quality of life, maintain the dignity, and make the access to the world a little bit easier by solving the particular clothing problems with all these convenient as well fashionable adaptive clothing.
The purpose of this study is, to renew understanding the aesthetic value of a ruff collar and to expand the border of creation in designing as the source of inspiration being applied to an retro style by inquiring various ruff collars re-illuminated in the present-day fashion trend. The ruff collar investigated through the above historical contemplation became the source of inspirations in the current retro trend and was variously modified in modern fashion. In the 1980s, we can find a dignified and feminine image in graceful and exquisite suits or dresses. Especially, the spanish round ruff of the 2st period appeared on works by a lot of designers. From the application by designers like John Galliano in the latter half of the 80s, we can be well aware that the meaning of decoration was newly altered. In the 1990s, the ruff collar was shown in various fashion style, but it was what was reborn as a factor of modern fashion through a liberal compromise and harmony. Various style was shown from exaggeratedly swelling one to smaller one, which were more diversely applied than that of the 80s. A Medici collar and a Queen Elizabeth collar were also displayed being fitted to a modern sense by Vivienne Westwood and Louis F raud. A ruff in the 2000s was settled as a factor of modern fashion, exposing on works of designers more often than in the 1980s and 90s. The spanish round ruff appeared on garments, while a Medici collar and a Queen Elizabeth collar went out of sight. A new form of the ruff was regenerated by extreme magnification and simplification, and several designers like Issey Miyake and Alexander Mcqueen brought forward a new way in materials and technical skills. According to this research, a ruff collar developed as a fashion factor which characterizes a certain period of time, reflecting the aesthetical sense of Renaissance and turning into various and distinct forms. Afterwards, it exerted influence on modern fashion. This is offering the source of inspiration to contemporary designers.

Due to environmental pollution and human hazards of some synthetic dyes, the global fashion companies are increasingly interested in eco-friendly products, especially natural dye. For the globalization of natural dyeing industry based on this concern, however, there are some deficiencies of standardization, specification, and conformity assessment on natural dyestuffs as well as natural dyeing process. These obstacles should be not only studied but also defined for a commercial transaction. Accordingly, a study for conformity assessment on commercialized natural dyestuffs (red) was conducted by HPLC analysis in this study. As the results of HPLC analysis, alizarin and purpurin, representative index ingredients, were detected in most of the samples, but the index ingredient content in each sample was different. In addition, some samples showed the variety of peaks including the index ingredients and others. It was inferred that the representative index ingredients could be used on the traceability of natural sourced dyestuffs. These results are related to the index ingredient consistency, standardization, and reproducibility of natural dyed products including such as yarns, fabrics, garments, and so on. Therefore, the present study was demonstrated that in order to determine the conformity assessment system for the satisfaction of all stakeholders, the offering of information on the origin, manufacturing process, and index ingredient content of natural dyes should be prioritized.
The use of standardized stitches in globalized apparel markets is becoming increasingly important. However, many apparel vendors still use disunified stitches, such as Japanese and English. This study analyzes the usage of clothing stitches of cut and sewn knit garment fabrication of small companies. The results of the analysis of 464 worksheets of cut and sewn knit garments are as follows. First, of the 464 worksheets, only 4.31% are labeled as ISO 4915 No. Among the 1,399 stitches, only 3.15% were marked with the ISO 4915 No. Second, among 1,399 stitches, ISO 4915 No. 406 followed by 401 was the most frequently used. Third, in the case of the top, ISO 4915 No. 406 was used the most; in addition, ISO 4915 No. 401, 301 and 304 were also frequently used. Fourth, in the case of the bottoms, the stitch with the highest frequency was ISO 4915 No. 406 followed by ISO 4915 No. 103 and 401, respectively. Fifth, in the case of the top, ISO 4915 No. 406 was most commonly used in hemlines and sleeve edges; in addition, in the case of the bottoms, ISO 4915 No. 406 and 103 were most commonly used as hemlines. In conclusion, it is important to use international standard stitches, especially for the most frequently used stitches. By using the standard stitches, the communication errors between production departments can be reduced and information can be accurately delivered.
