Technology status was investigated by analyzing patents and development cases of wearable robots. Development direction of wearable robot for wearability was also suggested by understanding the problems of wearability from development cases through the FGI technique. The number of patents per technical field was the most in the field of strength support, but AI in the technology field was different in each country; Korea was found to be poor in the category of daily living assistance. The number of patents by technology category was the most in the category of muscular strength assistance. However, the values of AI in the technology category were different in each country; Korea was found to be poor in the category of daily living assistance. Development cases were focused on rehabilitation, so development is not fulfilled uniformly by use purpose. By wearing body parts, robots with single function type were mainly developed. Rigid material robots were mainly developed. It was confirmed that wearable robot technology is not developed evenly in the category of application because it is in the early stage of the technical proposal and centered on main performance improvement. We derived twelve wearable conditions for wearable robots: Shape and Size Appropriateness, Movement Appropriateness, Composition Appropriateness, Physiological Appropriateness, Performance Satisfaction, Ease of Operation, Safety, Durability, Ease of Dressing, Ease of Cleaning, Portability and Ease of Storage and Appearance Satisfaction. Finally, the development direction of a wearable robot for each wearable condition was suggested.

Virtual reality is currently mainly used in games, but is starting to be applied as a variety of media fields, such as broadcasting and film. Virtual reality provides more fun than reality, and can provide new experiences in areas that cannot be experienced in reality due to the constraints of time, space, and environment. In particular, as the social non-contact arena has increased due to COVID-19, it is being applied to education, health, and medical industries. The contents are further expanding into design and military fields. Therefore, the purpose of this study was to observe the change in distribution of load and pressure felt by the body in the flying state while wearing a short pants harness, which are mainly used in the game and entertainment industry. In the experiment, the average pressure in the flying state was measured by attaching a pressure sensor to the back and front of a human mannequin. As a result, it was confirmed that the load concentrated on the waist in the flying state was 44 N, with a pressure of 1353 kPa. The pressure distribution was concentrated in front of the center of gravity, and was measured was at 98% by the pressure sensors, with an average pressure value of approximately 15 kPa, and a pressure value of approximately 12 kPa at the back, which was measured at 67% by the pressure sensor. The results of the load and pressure distribution measurement are presented as fundamental data to improve the wearability and comfort of harnesses in the future, and are compared to actual measured pressure values by analyzing the clothing pressure in flight through virtual wear of harnesses through the CLO 3D program.

This study is to understand the preferences of pilots, flight engineers and crew who work in the same aircraft but are exposed to different working environments and perform different mission operations in order to develop an ergonomic flight jacket. Based on a preliminary investigation, a survey of 107 pilots and 36 flight engineers and crew was conducted. The results are as follows; Pilots can control the temperature inside the cockpit, so they are less exposed to the cold when working, while flight engineers and crew are exposed to the cold more because they have many external tasks. The reason for the problem of the current flight jacket was a difference in ranking between two groups, but the highest ranking was poor dimensional suitability due to the habit of wearing layers of clothing. As a result of preferred design, there were significant differences between groups in the item of overall style. Pilots preferred a bomber jacket style(P:68.2%, E&C:44.4%), on the other hand, flight engineers and crew preferred a field jacket style(P:26.2%, E&C:55.6%)(p<.01). They preferred a stand collar(P:71.0%, E&C:86.1%), a fastener slider for a front fastening(P:62.6%, E&C:61.1%), fastener tape cuffs(P:54.2%, E&C:47.2%), a jacket with a softshell(P:86.9%, E&C:83.3%), fleece as softshell material(P:88.8%, E&C:69.4%), and fastener sliders as a attaching method(P:69.2%, E&C:61.1%). A hem fastening will be selected differently according to the overall style of outshell. Additionally, they preferred more than 5ea pockets(P:51.4%, E&C:44.4%), fastener sliders as pocket's fastenings(P:48.6%, E&C:61.1%), armpit ventilations(P:62.9%, E&C:58.5%). The results of above will be considered to design an ergonomic flight jacket.

This study aimed to develop a new Hanbok Jeogori prototype based on design extracted through a preference survey on new Hanbok Jeogori. This study was conducted based on K-patterns selected as excellent patterns in prior research and utilized the SPSS 27.0 program for analysis of appearance evaluation. As a result of the first appearance evaluation and garment pressure evaluation, the shoulder area was required to be modified, so the shoulder end point was moved within 1cm to rearrange the armhole line. Modification of sleeve length and circumference was also required, reducing sleeve length by 1.5cm and sleeve circumference by 0.5cm at both ends. As a result of the second evaluation, the length of Jeogori, hem circumference, and sleeve length were required, reducing the length of the front and back Jeogori by 1 cm and reducing the sleeve length by 1cm. The hem circumference was reduced by 0.2cm each in the princess line, which was highly evaluated in the final evaluation. In future research, it is thought that pattern studies by material, length, and age should be conducted and corrections should be derived through actual wear experiments.

Before the tenth century, the dress of elite women in and around China often reflected "Han" Chinese fashions and preferences. In funerary paintings and relief sculptures of Sogdian and Xianbei couples from the sixth century, for example, women wear "Han" Chinese-style clothing. Even in the Tang dynasty (ca. 618-907), when exchange with Central Asia via overland Silk Road trade impacted the styles and patterning of elite dress and men incorporated clear Central Asian attributes into their dress, elite women in the Tang sphere wore recognizably Tang fashions. Chinese-style dress in these centuries clearly conveyed cultural import and, likely, political power, especially after the founding of the Tang dynasty. However, the straightforward borrowing of Tang women's dress shifted in the Khitan Liao dynasty (ca. 907-1125). The Liao, in contrast to other states that shared a border with China in previous centuries, saw themselves as political equals to the Song dynasty (ca. 960-1278) court in the south. The Liao court was interested in Song customs and culture and incorporated artistic motifs and practices from the Song court. However, the Liao courtly idiom was never fully subsumed into the greater world of the Song - rather, the Liao used facets of Song courtly culture for their own ends. One way this is manifested is through the dual administrative system, a bureaucratic organization that, among other things, regulated and distinguished between who was permitted to wear Khitan and non-Khitan dress. In this paper, I will examine the material evidence from funerary contexts for how the dress of elite Liao women both engaged with the dress of the Song, while also maintaining a certain amount of cultural autonomy. Through their dress, elite Liao women signaled clear messages about their status, identity, and difference to their Song counterparts.

This study aims to analyze the macramé technique used in costume design based on the cases from 2011 to 2020, when the macramé technique became popular. The research data are the results of analyzing the materials, clothing items, and structural combination of macramé knots by season, year, and collection from 2011 S/S to 2020 F/W, focusing on the four major fashion collections New York, Paris, London, and Milan. Macramé appeared often in the S/S season, and in the 2019 and 2020 S/S seasons, macramé was identified as a keyword for fashion trends based on its frequent usage. Overhand knots were used the most for the types of macramé knots used in costumes, and overhand knots were also used the most in the S/S season and in the New York, Paris, and Milan collections. Rope was the most frequently used material for macramé knots, and it was confirmed that it appeared frequently in 2011 and 2019, and ropes were also used often in the London, Milan, and Paris collections. One-piece appeared the most in the S/S season and F/W season as costume items. In addition, the costumes used as layers in the S/S season appeared most often, and in 2019 and 2020, the layered combination appeared most frequently in London and New York collections. It is judged that macramé appears repeatedly in the S/S season depending on the type of knot and is used as a layered look, making it a decorative element rather than a practical element. This study is expected to help develop modern fashion design by drawing attention to the value of the macramé technique expressed as handcrafted work.

Radiation shielding clothing for medical institutions is used based on lead equivalent of 0.25 mmPb. However, this study intends to study the shielding suit that can guarantee the user's activity while considering the sensitivity of each part of the body. By manufacturing based on eco-friendly shielding material, it was attempted to solve the weight problem and environmental problem of existing lead aprons, and to present the same shielding performance as lead equivalent in thickness. The fabric of the produced shielding sheet was manufactured through a calendar process that adjusts the thickness of the shielding sheet from lead equivalent 0.12 mmPb to 0.32 mmPb. In addition, the usability evaluation of the manufactured shielding clothes was conducted for the subjects who were workers in medical institutions. As a result, the activity became easier and the weight was reduced by 0.26 kg. In the future, it is thought that it is necessary to improve the shielding suit design considering the activity.
