The aesthetic value of Korea is rising in various fields through the use of designs using Korean materials. Korean materials contain oriental ideas and are widely used as materials for design development due to the uniqueness of its form. The purpose of this study is to present basic data of nail art design differentiated nail art designs required at the nail art industry site by producing nail works using Korean materials. Accordingly, We proceeded on the basis of theoretical consideration and empirical research for the development of nail art design, a field of beauty in this study, and made a Korean and unique nail art design work using the Four Gracious Plants. For this purpose, we considered theoretically the characteristics of nail art and the Gracious Plants, and made nail art design works derived from empirical research. The work was analyzed by color, texture, and design elements of form. Therefore, the mixed method of Nail Art and the Gracious Plants, which is the core of this study, is considered to be meaningful in laying the foundation for creative nail art design development.

YouTube has established itself as a major media platform. Businesses give more attention to YouTube's influence as marketing using the platform demonstrates positive effects. Accordingly, this study aims to look into how the quasi-social interaction of the users of beauty content on YouTube affect purchase behavior intentions and provide results as basic data for establishing an efficient marketing strategy. Quasi-social interaction exerted significantly positive influence on purchase behavior and purchase intention. This suggests that the stronger the quasi-social interaction becomes, purchase behavior and purchase intention get stronger. Therefore, strategies for facilitating marketing should be devised by increasing efficient quasi-social interaction according to user characteristics.

In this paper, we investigated the implementation of a hairstyle recommendation system based on big data and deepfake technology. The proposed hairstyle recommendation system recognizes the facial shapes based on the user's photo (image). Facial shapes are classified into oval, round, and square shapes, and hairstyles that suit each facial shape are synthesized using deepfake technology and provided as videos. Hairstyles are recommended based on big data by applying the latest trends and styles that suit the facial shape. With the image segmentation map and the Motion Supervised Co-Part Segmentation algorithm, it is possible to synthesize elements between images belonging to the same category (such as hair, face, etc.). Next, the synthesized image with the hairstyle and a pre-defined video are applied to the Motion Representations for Articulated Animation algorithm to generate a video animation. The proposed system is expected to be used in various aspects of the beauty industry, including virtual fitting and other related areas. In future research, we plan to study the development of a smart mirror that recommends hairstyles and incorporates features such as Internet of Things (IoT) functionality.

In the rapidly changing 21st century, image management has become more important. Under these circumstances, as a lot of hair colors and beaching agents are used to create diverse hair colors, hair damage resulting from frequent chemical hair coloring has been inevitable. This study investigated how to reduce morphological changes in hair and hair damage after dividing hair into healthy hair('Group A') and damaged hair('Group B'), using the following bleaching agents: basic bleaching agent(a), beaching agent diluted with water(b), oil ingredient-added bleaching agent(c), water-shampoo mixed bleaching agent(d). The results found that even though hair damage can be prevented by a bleaching agent diluted with a mixture of diverse additives, there were better effects on hair texture in both 'Group A(4.83)' and 'Group B(4.41)' at a sensory test when hair was bleached with an addition of Camellia oil, according to blinded experiment, in particular. As a result, hair damage could be reduced. Therefore, this study expects that hair bleaching with an addition of Camellia oil to the mixture of a bleaching agent would bring the development of diverse new materials which can minimize hair damage as well as regulate hair brightness and make a contribution to the development of cosmetology market.

The cosmetic and stimulating effects of lemon oil have been widely proven in the fields of beauty therapy and psychology therapy. But the lemon oil's proper effects on the anti asthma and the anti inflammation have not rarely been verified. This study was conducted to find out the lemon oil's effects on the anti asthma and anti inflammation in the OVA-induced allergic asthma mice model. OVA-induced allergic asthma mice were divided into 4 groups consisting of normal group, control group, positive control group and experimental group. 0.3% of lemon oil was nebulized to experimental group for 3 weeks on a basis of 3 times per week and 30 min each time. After 6 weeks from the initial experiment, the degree of hyper activeness of respiratory system, the hematological change, the amount of the cytokein in serum, the change of airway organization were evaluated. The results showed that lemon oil controled effectively the hyper activeness of respiratory system and restricted the multiplication of cells in acidophil in terms of statistical significance. It also turned out that lemon oil restricted effectively the infection of airway reaction and the hyper sensitiveness of respiratory system by controlling the creation of histamine(cytokein) and IgE.

This study aims to prevent maternal social isolation by analyzing the causes of postpartum obesity and postpartum depression and stress in Korea. Gneral characteristics of mothers as a result of the study: 91.1% (102 people) answered that they had social experience, and only 8% (9 people) answered that they had no social experience. In the question of whether to return to society, 17.9% responded that they have already returned, 54.5% did not, and 18.8% were on maternity leave. As a result of examining the level of BMI increase among mothers through chi-square test of BMI changes before and after childbirth and general characteristics, 55% experienced below-average BMI increase; 45% experienced above-average BMI increase. Those in their 30s accounted for 40.2%, and those in their 40s accounted for 57.1%. Postpartum obesity and maternal psychological status (t-test): Mothers with postpartum obesity were more hypersensitive (t = -1.997, p = 0.048) and more prone to suffer from hard breathing (t = -1.930, p = 0.056), emptiness (t = -2.673, p = 0.010), and body numbness (t = -2.315, p = 0.024) than mothers who are not suffering from not postpartum obesity. Per the results of postpartum BMI increase and maternal psychological state (t-test) analysis, mothers with an average increase in postpartum BMI were more depressed than mothers who did not. Research Results - Postpartum obesity due to pregnancy and childbirth has been identified as an important individual cause affecting mental and physical problems after childbirth. In conclusion, I also think that the government should support the management of maternal obesity and the elimination of depression through the results of this study.
