피부의 관리를 위한 방법 중 광을 이용한 케어는 비침습적인 방법으로 세포를 활성화 시켜 도움을 주는 매우 유용한 방법이다. 최근에는 낮은 에너지의 LED를 광원으로 이용하는 LLLT (Low Level Light Therapy)가 많이 적용이 된다. 본 논문에서는 피부 미용기기에서 많이 사용되고 있는 가시광 영역의 적색과 황색, 그리고 적외선 영역의 LED를 이용하여 array를 제작하였다. 제작된 LED array는 5V의 전압과 50mA의 전류로 구동되며, 적색이 평균 $10.7mW/cm^2$, 황색이 평균 $1.8mW/cm^2$, 적외선이 평균 $5.5mW/cm^2$의 광출력을 갖는다. 이를 배양된 human cell plate에 각각 10, 20, 40분의 시간으로 조사하였으며, LED array와 조사면 사이에 20 mm의 거리를 두어 균일한 광량이 조사 될 수 있도록 하였다. 실험결과, wound healing의 경우는 적색광을 조사하였을 때, injury line의 길이가 $604.36{\mu}m$에서 10분 조사 시 $368.92{\mu}m$, 20분 조사 시 $298.04{\mu}m$, 40분 조사 시 $491.22{\mu}m$로 줄어드는 효과를 보였으며 특히 20분간 조사하였을 경우의 효과가 가장 좋았다. Cell regeneration의 경우는 황색광을 20분간 조사하였을 경우에 UV 에 의해 손상된 세포 수가 가장 크게 줄어드는 것을 확인할 수 있었다. 결과적으로 photorejuvenation 효과를 줄 수 있는 wound healing과 cell regeneration에는 적색 및 황색광의 LED array를 20분간 조사하였을 때가 가장 효과적이었으며, 적외광의 경우에는 모든 실험에서 효과가 없음을 확인할 수 있었다.

Hot spring water is underground water which naturally flows out to the earth's surface or is drilled for artificially and the water temperature should be higher than the region's average temperature for the year or underground water temperature of the earth's shallow strata of the region. Our nation stipulates that hot spring can be called if it is over $25^{\circ}C$. Generally, it is widely know that hot spring water has an effect on blood circulation, pain alleviation, soothing, and skin care and that its efficacy is mainly due to water temperature and a variety of minerals contained in water. The Onyang springs are the oldest spring district in our country and one of the most typical hot springs in this country. The current study found that there's no skin irritation through the skin irritation test applying hot spring water to cosmetic formulas, and that products using Onyang hot spring water showed an increase of 8.56% in epidermal water rate and a decrease of -67.74% in relative transepidermal water loss(TEWL), which indicates that cosmetics using Onyang hot spring water has an effecton skin improvement.

The purpose of this study was to examine the relationship of body-shape perception and periodontal diseases in female adolescents based on the sixth 3rd-year(2015) data of the National Health and Nutrition Examination Survey. The subjects in this study were 211 female teenagers who were at the western ages of 12 to 18. As a result of analyzing, it's found that the body-shape perception of the female teens were linked to age, sleep hours, BMI, weight control and toothbrushing frequency, and whether they had periodontal diseases or not was found to be under the influence of age, smoking, sleep hours, stress, BMI and toothbrushing frequency. When the relationship between their body-shape perception and peridontal diseases was analyzed by controlling the confounders, the adolescents who considered their own bodies to be obese suffered from 3.18-fold more periodontal diseases(OR=3.18, 95% CI: 1.21, 8.38) than the teenagers who considered their body shape to be average. In the future, oral health care should be provided in consideration of the mental health of female adolescents to prevent periodontal diseases.

This study was conducted to identify the using self-nail products for the purpose of developing indicators to respond to changes in nail industry due to the evolution of consumption patterns caused by the spread of self-nail culture. The final analysis of 293 survey was conducted on female adults living in South Gyeongsang Province from September 1, 2018 to October 30, 2018. The study found that women in their 20s were more interested in nail care than in most cases. The main route of obtaining nail-related product information was the higher the use of SNS as the age was younger(${\chi}^2=185.048$, p<.001). According to a survey of 165 people who have experience with self-nail products, 53.3 percent of 'paste stickers' were the most common, followed by 39.4 percent of 'paste nail tips' and 7.3 percent of 'home care products'. Looking at the disadvantages of self-nail products, between groups under their 50s and over 50s group saw a significant difference(${\chi}^2=27.032$, p=.008). For those in their 50s or younger, 'the inconvenience of daily life' was considered a disadvantage. On the other hand, people in their 50s and older considered 'short duration' as a disadvantage. The lower the age, the higher the willingness to use continuously(${\chi}^2=14.308$, p=.006).We found that there were differences in preference for self-nail products according to age. It was noticed that there were differences in satisfaction and persistence. This suggests the need for more specific follow-up studies on the use of self-nail products by age group. Therefore, this research aims to present basic data for the development of direction and custom program for the professional nail industry to advance, thus providing basic data to help the development of nail industry in South Gyeongsang Province.

This study analyzed the Internet consumption behavior concerning pet care through in-depth interviews with 11 people who take care of pets. In this study, along with owners of domestic companion animals, stray cat caregivers were included as pet consumers, which have not yet been included in this category in existing research. Internet consumption was found to differ between people with dogs and people with cats. In the case of dog owners, they bought a lot of bath products, clothes harnesses, and strollers that were not appropriate for cats. Although the pet-poor phenomenon is known to occur a lot among young consumers, who care for pets behavior at the cost of money spent on themselves, even stray cat caregivers, mostly middle-aged women, are wary of becoming pet-poor. It cannot be said that there are gender differences in online shopping of pet consumers. In general, women, who did mainly Internet shopping, and if they are not used to using the Internet, their husbands made purchases online instead.

This study is aimed at suggesting a direction for the development of sensuous and creative art mask design by making art masks rooted in the aesthetic characteristics of psychedelia. The conceptual definition and characteristics of psychedelia were identified on previous studies, specialized books and works of art. The characteristics of psychedelia based on theoretical research were limited to illusionism, abstraction, play, and dynamism, which are often used in researcher's work, and four research works were produced by combining them with art mask design. By trying to diversify works regardless of form or tradition, this study could make the infinite creation of art mask possible and transform that into a new modern beauty. In addition, by expressing internal meaning along with external characteristics in the design of works, it could bring the establishment of a new perception and value of art mask. In the future, it is hoped that this study will be used as basic data for follow-up research related to art mask design and be helpful in the development of art mask design.
