Background: Thermophysiological comfort in a cold environment is mainly ensured by clothing. However, the thermal performance and protective abilities of textile fabrics may be sensitive to extreme environmental conditions. This article evaluated the thermal insulation properties of three technical textile assemblies and determined the influence of environmental parameters (temperature, humidity, and wind speed) on their insulation capacity. Methods: Thermal insulation capacity and air permeability of the assemblies were determined experimentally. A sweating-guarded hotplate apparatus, commonly called the "skin model," based on International Organization for Standardization (ISO) 11092 standard and simulating the heat transfer from the body surface to the environment through clothing material, was adopted for the thermal resistance measurements. Results: It was found that the assemblies lost about 85% of their thermal insulation with increasing wind speed from 0 to 16 km/h. Under certain conditions, values approaching 1 clo have been measured. On the other hand, the results showed that temperature variation in the range (-40℃, 30℃), as well as humidity ratio changes (5 g/kg, 20 g/kg), had a limited influence on the thermal insulation of the studied assemblies. Conclusion: The present study showed that the most important variable impacting the thermal performance and protective abilities of textile fabrics is the wind speed, a parameter not taken into account by ISO 11092.

Ear keloids are challenging lesions to treat due to high recurrence rates postexcision. Conservative compression techniques as adjunct treatment have been reported to be effective. An innovative technique of using computer-aided design/computed-aided manufacturing to print a customized auricular splint improves efficiency and comfort level for patients compared with conventional methods. The ear is scanned using an intraoral scanning 2 weeks postsurgery. A two-piece auricular splint is designed on the digital model, incorporating perforated projections for three nylon screws for retention of the splint. The splint is printed with clear acrylic material, postprocessed, and finished. The patient is taught to assemble the components of the splint and instructed to wear for at least 8 hours daily. The surgery site reviewed for any ulceration, pain, or recurrence of keloid for 6 months. During the 6-month review, the excision scar remained flat and pink. The patient also reports unrestricted daily activities. The digital workflow increases comfort for the patient and reduces the number of hours required to produce a customized auricular splint compared with conventional methods. A fully digital workflow for a printed auricular splint should be considered for adjunctive treatment to excision of ear keloids.

The purpose of this study was to determine the practicability of an experimental protective clothing by identifying the human body's physiological responses to it as well as the human body's comfort level when wearing it, particularly with the use of a processed charcoal material. The experimental protective clothing came in two types: one whose outer side made use of polypropylene film, and the inner side, a non-woven rayon fabric; and one whose inner side made use of a non-woven fabric processed with charcoal with a 10% density. Experiments were conducted on five healthy adult women whose average age was 21. These experiments were conducted at a climatic chamber, in which the temperature and relative humidity were set below $28{\pm}1^{\circ}C\;and\;50{\pm}10%$, respectively, and were measured within a period of 60min, consisting of a 20-min rest period, a 20-min exercise period, and a 20-min recovery period. Based on the results of this study, the efficiency of the processed charcoal material was reviewed, and a database requiring the production of more functional and comfortable protective clothing materials was established.

This research was designed to investigate the preference for underwear and textiles of college students according to season. One hundred and nine subjects majoring in fashion design were surveyed about the most favorite materials among underwear textiles according to each season. The extent of preference was compared by season. The results of this study were as follows: 1. The most important purpose of wearing underwear was the hygienic performance in summer and the insulation in winter. 2. The most favorite textile of underwear was cotton regardless of season and the most favorite type of underwear was fashionable underwear in summer and insulating underwear in winter. 3. The most preferred material underwear was white jacquard knitted with cotton 30's yarn for summer and white and gray melange plain knit made with cotton and polyester blended 38's syro-spunned yarn for winter. 4. From the results about the factors influencing on the preference for the textiles of underwear, color, touch and cool sensation were the positive factor in summer, while insulation and pattern were comparatively affirmative factor in winter. 5. From the results about the sensibility factors influencing on the preference for the textiles of underwear, 'comfort', 'refined', 'naive' were the positive factor in summer, while 'comfort', 'naive', 'refined' were comparatively affirmative factor in winter. From the above results, hygienic and fashionable underwear is required in summer and thin and insulating underwear in winter for young people. Additionally, in textiles, cotton and cotton blended, comparatively light and simple patterned material is recommended for underwear.

The study has been intended to find out meaningful information about the development of a prototype of enhanced maternity girdle. The girdles of three different models which were available in the market have been carried out by three six-month pregnant women and three nine-month pregnant women. The results of the study are as follows. 1. All three girdles showed improved wear effects in order of model A, model B, model C. Body surface area measurement and two body surface angles of abdomen are significantly dicreased by wearing and type of girdles. It is presumed that the reasons of good wear effect of model A is low expansion rate of the material and tight fitness of the model. Model B is made of material whose expansion rate is higher than model A. Also abdominal part of the model B is bias cut which is considered to result better stretch and consequently lower wear effect. 2. For wear comfort, subjects preferred in order of model B, model C, and model A. All subjects feel more comfortable after wearing girdles 30 minutes than after wearing girdles 1 day. Comparing 2 subject groups, 6-month pregnant group feel more comfortable about wearing girdles than 9-month pregnant group. 3. The girdles are expanded as a whole in order of model B, model C and model A. Considering the expansion rate of some specific area of the girdles, abdominal area expands more than hip area which expands more than thigh area. The expansion rates of girdles worn to 6-month pregnant group are very low at all area, while the expansion rates of girdles worn to 9-month pregnant group are very high.
