Purpose: We analyzed the influence of myopic's eye-glasses wearing on myopia progress after cycloplegic refraction. Methods: The 33 people (66 eyes) were school children from 8 years to 12 years having no experience eye-glasses wearing, they were taken cycloplegic refraction at the 100th, the 200th and 300th days in order to evaluate myopia progression. We investigated the eye-glasses wearing group (experimental group, 32 eyes) and the non-eye-glasses wearing group (control group, 34 eyes). The eye-glasses power of the experimental group were -0.50 D, -0.75 D, -1.00 D, -1.25 D and -1.50 D. We compared experimental group with control group for myopia progress according to period, age, and refraction error and investigated the myopia progress according to the eye-glasses power of experimental group. Results: At the 300th day from the first cycloplegic refaction, spherical equivalent for the experimental group increased as -1.03${\pm}$0.43 D (t=13.36, p<0.001) and for the control group increase as -0.61${\pm}$0.35 D (t=10.05, p<0.001) and two groups were statistical difference. Myopia power for experimental group increased 60.75%, for control group increased 56.66% at the 300 days. According to eye-glasses power increased 41.19${\pm}$15.25% at -1.50 D, 36.74${\pm}$19.29% at -1.25 D, 56.57${\pm}$20.21% at -1.00 D, 87.26${\pm}$49.38% at -0.75 D and 106.69${\pm}$59.60% at -0.50 D. Conclusions: The myopia power for the eye-glasses wearing group was 0.46 D faster than the non-eye-glasses wearing group at the 300th day from the first cycloplegic refraction. We will consider the effect of non-eye-glasses wearing to protect the progressing myopia and prescribe the under correction for school children having no experience eye-glasses wearing.

This study aimed to investigate the perceptions and preferences of foreigners residing in Korea towards K-fashion. It sought to provide suggestions for the future development of K-fashion targeting this growing demographic. The results revealed that the longer foreigners had lived in Korea, the more positively they rated Korean fashion, shopping, and culture. The majority of foreigners purchased K-fashion items online, with popular choices including T-shirts, jackets, shirts, and jeans. Both men and women identified shoulders as a common problematic area when wearing clothing, with some issues also reported in the lumbar region. In terms of preferences, younger males (teens and twenties) were more inclined towards fads and celebrity wear compared to older males (thirties and forties). Similarly, younger females (teens and twenties) showed a higher preference for functionality and celebrity wear compared to older females (thirties and forties). These findings suggest that men tend to prioritize aesthetic factors when choosing K-fashion, while women prioritize practical considerations. To better cater to foreign consumers, suggestions for the development of K-fashion include promoting it through K-pop stars, considering dimensions related to foreigners' shoulders when designing top items, diversifying colors, sizes, and patterns, and providing English versions of online shopping platforms.

The recent trend in younger generations of wearing traditional costumes or incorporating fusion hanbok into daily wear necessitates the development of modern hair accessories to complement hanbok. The purpose of this study is to develop practical and modern hair accessory designs inspired by royal women's hair ornaments that complement hanbok, and therefore expand the scope of fashion content development utilizing hanbok culture as well as meeting the demand for various experiences of traditional culture. This research studied the literature on traditional hairstyles and accessories of Queen Yeong and constructed models of these accessories for the purpose of empirical research. The production process first required creating a basic foundation of nylon mesh reflecting the silhouette of a traditional hairstyle, and then grafting a digital textile printed fabric using majestic and extravagant royal relics on top, thus employing the trompe l'oeil technique to ultimately give the impression of wearing traditional jewelry. As a result, a total of six hair accessory designs were completed, produced with hairbands, hair pins, and hair ties. In addition, the accessories are designed to be easily worn regardless of the wearer's hair style, and the stiff yet flexible nylon mesh effectively expresses the shape of a voluminous hairstyle and creates an optical illusion, blending into the hair. These research results present a unique aesthetic and cultural experience to the greater public seeking both daily entertainment and value from rarity.

Despite a rapid market growth in VR, cyber sickness has become the most serious problem in terms of user experience. The aim of this study is to verify whether there are differences in user's perception of cyber sickness by the point-of-view and the movement in VR contents. An experimental testing of game playing with VR headset was conducted on the effects of two conditions: first-person and third-person views in the point-of-view condition, and yaw - pitch rotations in the head movement condition. The results showed that cyber sickness worsened in the first-person point-of-view and in the yaw rotation movement. Point-of-view and movement had main effects on the cyber sickness, but an interaction effect between point-of-view and movement was not found. Based on the findings, along with reducing VR sickness, we proposed practical implications for VR contents planning for building balanced VR user experience. Positive VR experience can be reinforced through visual design, multi-modal interface design, and experience marketing for the optimal level of contents immersion. A future research was suggested on the roll rotation for diverse content genre development.

The health of feet is connected with individual's health and affects a man's activity. Shoes need to be designed to protect feet and to absorb the impact of land. Thus, design, comfort and economical efficiency are important factors of shoes. Consumers can choose suitable shoes for their feet in off-line shopping. However, in on-line shopping, because they can not wear shoes, compare to the off-line shopping, there are many problems in internet shopping. First, consumers can get limited information of shoes because they must search information of purchase without other's help. Second, because consumers can not get important information such as design, size and a comfort of wearing, they can not make a careful decision. Above these, the solution of user-oriented internet shopping is development of new type of prototype which is accessible to user and to offer visual information through 3D virtual reality.
