Purpose: The present study was conducted to investigate the effect of the physical properties of RGP lens induced by lens polishing on the actual wearer's subjective comfort, the tear film break-up time and the blinking rate as a follow-up study that revealed the relationship between the lens physical properties during lens manufacturing and lens wearer's factors. Methods: RGP lenses made from the three different polishing conditions (25, 50 and 100 seconds) were applied on 28 eyes of 17 subjects, aged 20 to 29 years, without any known disease and surgical history in the eyes. While the subjects were asked to wear the RGP lenses longer than a week, the questionnaire for the comfortability was administered everyday. Subjective and objective tear break-up time and blinking rate of the wearers were further measured. Results: The wearer's subjective comfortability showed some difference in the type of discomfort and satisfaction score according to the polishing status when wearing RGP lenses made from different polishing conditions longer than a week, and a bigger difference in satisfaction score induced by polishing condition was especially shown in experienced RGP lens wearer rather than un-experienced wearer. In the case of RGP lens wearer compared with the ones without the wearing experience, as the wearing time increased subjective and objective tear break-up time were increased and the blinking rate was decreased. However, subjective and objective tear break-up time were tended to decrease with even longer wearing time when wearing the RGP lens made from the polishment for 100 seconds. Conclusions: These results confirmed that the optimization of physical properties of the lens may not give the same effect on the wearer's subjective and objective symptoms and other factors when actual wearing. From the results, it can suggest that the success rate of RGP lens wear may be changed by physiological factors such as the stabilization of wearer's tear film, comfortability and lens wearing experience when wearing RGP lens based on 'The manufacturing standard for soft contact lens/hard contact lens' provided by Korea Food and Drug Administration.

The purpose of this study was to confirm the difference of garment pressure and comfort depend on age group wearing the Korean skirt-band. A loadcell was used for measuring garment pressure, and 25 female subjects were chosen for each of young, middle, and old age groups. Garment pressure was measured in front, side, and back parts of the body. The results were as follows: 1. The younger the subjects, the greater the garment pressure. This suggests that the young age group wear the Korean skirt-band more tightly than needed. 2. The measurements of the pressure in 3 parts of the body were different. In young and middle age groups, pressure decreased from side to back, while in the old age group the order was side, back, and (rent. 3. The young age group felt high restriction of pressure. And the pressure in side part of body is the greatest among the three measurement.

The purpose of this study is to analyze the subjective fabric hand of sleepwear fabrics, and to assist in developing sleepwear fabrics that offer maximum comfort in wearing sensation. In general, the respondents noted that sleepwear fabrics made with polyester had better tactile sensation than those made with cotton, while satin weave fabrics felt better than plain weave fabrics. As regards the difference in fabric hand according to gender, female students responded with more receptiveness and sensitivity than male students in the category of woven fabric evaluation. As regards the same textile materials, the evaluations of female students and male students differed in fabric hand descriptors, particularly for the evaluation on cotton fabrics. Male students responded that both plain weave fabrics and satin weave fabrics were stiff while female students replied that satin weave fabrics had better tactile sensation.

This study investigates clothing pressure and subjective sensations in brassieres depending on breast type or bra type. The results of this study show that clothing pressure and subjective sensations were significantly influenced by breast type. The flat type breast and drooping type breast have a lower subjective satisfaction. Satisfaction for 3/4WL is the largest; however, 1/2W having low preventing breast shake and no-wire bra having low bust-up or low arrange-breast are required enhancements in bra function. The results are useful to provide basic data and produce high-quality brassieres depending on breast type.
