There have been in the history of western costume a few studies on men's headgear that cannot be the second to the women's headdress in terms of the gorgeousness and variety whereas the studies on women's hair styles and head dresses have frequently been carried out. Such varieties of the headgear in terms of forms and ornaments have still been found with various types. Thus, the study on the change in designs and details of headgear and the recreation of them may contribute to the utilization of the fashion in current vogue and the guidance of the creation for the new design. The aim of this study is to find such changes in the designs and the methods for the production of bonnets which have played important roles to emphasize external characteristics of costumes. As a result, this study may provide key materials for the development of new designs. As with the previous studies on the women's headdress and men's hat, the methodology of this study is to recreate bonnets based on the literature review and the portrait analysis. this study will cover the eras from the late fifteenth century to the mid sixteenth century when bonnets began to be produced. First, the characteristics of hair styles and bonnets are to be reviewed for the selection of bonnets to be recreated. Next step is to make a literature review on the form, materials, colors and ornaments used for bonnets. Finally, the patterns of bonnets is to be illustrated for the reproduction of selected bonnets. Materials to be used in this study for such a reproduction are velvets, silks and wools as presented in the literatures and ornaments to be used are similar to those captured in photos.

The purpose of this research is to develop a basic pattern of corset look taking into consideration characteristics of human body and fit, by transforming 3 dimensional information obtained from draping of standard body type of women in their 20s, which constitute the biggest consumer group of corset look in Korea, on the basis of body shape of women best reflecting 3 dimensional characteristics. In order to develop a corset look pattern suitable for standard body type of women in their 20s, wear tests of A, B, and C types of patterns in terms of the bust in the standard body type that bust circumference 86.7cm and chest circumference 87.0cm were evaluated best. Taking into consideration above findings, fer the purpose of developing a corset look pattern having an excellent fit and reflecting characteristics of Korean women in their 20s with standard body type, a corset look pattern was designed with proper ease calculated by draping incorporated, and through alteration and complementation of such a pattern, a study pattern was produced. This study is expected to provide tips for standard body type women in their 20s with smaller bust circumference to choose clothing allowing for a better fit able to make up for weakness of their body, while presenting to clothing makers ways of designing and size-setting in terms of characteristics of body type of these consumers.

The purpose of this study is to provide a basic data of clothing development which can improve the satisfaction of the body shape by examining the subjective evaluation and type characteristics of the old-old women themselves. Q methodology was used for the study of subjectivity. The types of the body shape of the old-old women were analyzed as five types: bent body with protruding abdomen, backward bent body with slender legs, inverted triangle, swollen cylinder, triangle. The bent body with protruding abdomen had a bent back and waist. They were recognized that the bust and shoulders were sagging and abdomen was protruding. The backward bent body with slender legs was the smallest of the five types with a BMI index and shoulders and bust were sagging. And knee and waist were bent and legs were thin. The inverted triangular shape showed the highest BMI index among the 5 types, indicating that it is obese. They thought that the upper body was developed and the lower body and legs were slender. The swollen cylinder shape was analyzed to be the smallest and the most fat body. The triangle shape had developed lower body and bent back and waist. It is considered that a design consideration is needed to cover the disadvantages of the body shape in consideration of not only wearing feeling but also aesthetic part when making clothes. By making ergonomic garments considering the characteristics of body shape, it can be expected to change the body shape due to the wearing of clothing that is not suitable for body shape and the effect on physical health in a positive direction.

This study explored the feasibility of utilizing an SWCNT-coated fabric sensor for the development of a wearable motion sensing device. The extent of variation in electric resistance of the sensor material was evaluated by varying the fiber composition of the SWCNT-coated base fabrics, attachment methods, number of layers, and sensor width and length. 32 sensors were fabricated by employing different combinations of these variables. Using a custom-built experimental jig, the amount of voltage change in a fabric sensor as a function of the length was measured as the fabric sensors underwent loading-unloading test with induced strains of 30 %, 40 %, and 50 % at a frequency of 0.5 Hz. First-step analysis revealed the following: characteristics of the strain-voltage curves of the fabric sensors confirmed that 14 out of 32 sensors were evaluated as more suitable for measuring human joint movement, as they yield stable resistance values under tension-release conditions; furthermore, significantly stable resistance values were observed at each level of strain. Secondly, we analyzed the averaged maximum, minimum, and standard deviations at various strain levels. From this analysis, it was determined that the two-layer sensor structure and welding attachment method contributed to the improvement of sensing accuracy.

It is important to compare and analyze digital camouflage from different countries to promote the continuous development of a camouflage combat uniform. This effort should lead to developing a camouflage pattern suitable for the domestic environment and expand its performance of night camouflage. This study investigates digital camouflage by comparing camouflage fabrics sampled from Korea and eight other countries (USA, UK, Singapore, Croatia, Colombia, and Mongolia) in terms of textile, near-infrared reflectivity of colors, and color distribution. First, the fabric construction of camouflage from Korea, UK, US, Singapore, Span, and Croatia were all characterized by derivative plain weaves, while derivative twill weaves were generally used in Croatia and Mongolia. It is assumed that derivative plain weaves are adopted to improve the tearing strength of fine yarns. However, twill weaves enhance the flexibility of coarse yarn fabrics. Next, reflectivity change was analyzed based on camouflage color. The reflectivity of a combat uniform in Korea, Colombia, Croatia, and UK increased before 780nm in the visible light range, but remained consistent from 800nm which falls under the near-infrared range. In contrast, camouflage samples in Mongolia, Span, Singapore and USA showed a gradual increase of reflectivity in the near-infrared range. Finally, the color distribution analysis of digital camouflage found that camouflage of countries with desert or woodland combat settings dominantly contained brown colors. It indicates the color pattern consideration of different geographic regions is important to determine camouflage performance. This research involves basic study that will have implications for developing patterns and colors suitable for the South Korean environment and expand its use as night camouflage that helps achieve continuous improved camouflage performance.

The purpose of this study was to analyze the direct measurement data of 40-59 year old middle-aged men from Size Korea's 7th anthropometric survey, and to identify the body shape characteristics and to type the body shape of middle-aged men. Through this, this study aimed to provide basic data necessary for the clothing patterns of middle-aged men with excellent fit. The data was SPSS Ver. 24.0 program analysis. Factors extracted six including body horizontal, vertical, shoulder, waist front length, leg thickness, and shoulder deflections. The body shape of middle-aged men was classified into three types. Type 1 had a thin body circumference, a narrow width, a low height, a short waist front length, and a thin ankle and calf. Type 2 had a high body height, a long waist front length, a normal circumference and width, a thick ankle, a calf, and a sagging shoulder. Type 3 had a large body circumference, a wide body, a wide shoulder, and a long waist front length. A prominent feature of the changes in body shape of middle-aged men is the increase in the circumference and thickness items due to abdominal protrusion and fat accumulation. Therefore, pattern design according to these physical characteristics is considered to be necessary.

This review shows the design and the development of new $CO_2$-soluble hydrocarbon copolymers which can be used as effective stabilizers for successful dispersion polymerizations of bio-compatible materials in supercritical carbon dioxide ($scCO_2$). The basic concepts of supercritical fluid including its solvent properties and applications in polymer synthesis are described. We report the facile synthesis of highly soluble hydrocarbon based copolymers, prepared with good control via controlled free radical polymerization from readily accessible and commercially available monomers. The phase behaviour of these materials was monitored in pure $CO_2$ to investigate how the molecular weights and the composition of the copolymers affect their solubility in $CO_2$. Their activity as a stabilizer was then tested in dispersion polymerization of N-vinyl pyrrolidone in $CO_2$ at various reaction conditions to identify the key parameters required for a successful dispersion stabilization of growing PVP particles. Some prospective potentials of this research which can be applied in developing new polymer materials in an environmentally-friendly fashion for use in cosmetics are also discussed.

This study aims to develop a life-friendly, wrap-one-piece style dance sports practice wear considering the physical characteristics of middle-aged, abdominally obese women. These types of practice wear allow people to enjoy exercise easily and to wear these garments as daily wear while meeting the requirements for dance sports wear. The three participants selected for this study were all women with five or more years of dance sports experience and were all average sized on Korea's abdominal obesity scale. In the first phase of the study, practice wear was created in a total of nine styles with three different styles of neckline depths for three different styles of dress skirt lengths. In the second phase of the study, the practice wear was created in 15 styles with five different styles of sleeve lengths for three different styles of waistline heights. After analyzing the design preferences of the participants, the fit preferences of the designs were evaluated and the final appearance was analyzed in order to suggest a pattern. The results of the subjects' first and second preference evaluations showed a preference for a 10 centimeter neckline depth, for high waistlines, and for elbow to wrist-length sleeves. The implementation of this research is expected to be extensive, as its results can be used as basic data for making lifestyle dance sports practice wear that covers the physical insecurities of middle-aged, abdominally obese women and enables them to enjoy their leisure time.

This study attempted to investigate what kind of perception people in their 20s have about masks and to find out the characteristics of each type by categorizing the perception. The Q methodology was used for the study. The cognition types of masks were categorized into three. Type 1 was a 'always wear impact-important type' that always wears masks and thinks masks affect non-verbal communication and the wearer's image. Type 2 was a 'function-important negative recognition type' that wears masks to prevent germs and thinks that masks have a great negative impact. Type 3 was a 'concealment wear positive image type' that wears a mask to cover the face and thinks that a person looks young when wearing a mask. It is thought that the development of masks of various designs and functions reflecting the needs of consumers should be carried out. Also, it is thought that various products should be developed and sold so that consumers can choose according to important considerations such as design, fit, and function.

This study attempted to compare the pattern with the absorption layer by analyzing the pattern of commercially available urinary incontinence panty products. Through this, it tried to obtain basic data necessary for the development of functional urinary incontinence panty for active seniors. Twelve commercially available products were decomposed to analyze size and patterns, and appearance and clothing pressure were evaluated through 3D simulation. As a result of comparing the size and pattern of urinary incontinence panty, it was analyzed that the size difference between parts was large even though the product was called the same. Products from the same brand also showed a big difference depending on design and absorption. As a result of the appearance evaluation for the 3D simulation, it was found that there were significant differences between products in all items such as the front, side, and back. Product No. 9 was analyzed to be the best except for the waist fit on the side. In the evaluation of clothing pressure, most of them were marked in red except for products 1, 2, and 8 due to the nature of the panty product. In the future, it is thought that actual wearing experiments and size standardization studies on urinary incontinence pants should be conducted.
