This study aimed to identify factors influencing awareness and interest in male nail care and nail art among people in their 20s and 30s, using a survey that included 390 men and women. The survey consisted of sub-factors, including awareness of appearance management, interest in nails, perception of male nail care and nail art, behavioral factors in nail care, and image factors in nail care. The results showed that the overall average interest in male nail care and nail art was 3.76, which fell between "average" and "yes". Women showed higher interest in male nail care than men did. While there was no statistically significant difference in the average value, interest in male nail care and nail art was higher among those in their 30s than those in their 20s. Unmarried individuals showed more interest in male nail care than married ones, and higher levels of education were associated with higher interest. In terms of occupation, service workers showed the highest interest in male nail care and nail art. In conclusion, the findings suggest the need for marketing research that caters to the development of services and programs targeting the male nail industry. The study also highlights the importance of segmenting and differentiating marketing strategies that target male and female customers with a high interest in male nail care and nail art. Based on these findings, this study aims to provide direction for the male nail care industry and serve as a basis for the development of customized programs. Additionally, it aims to provide basic data to aid in the development of the nail industry in Gyeongnam.

This experiment was carried out to investigate the effects of nail diameter, driving distance from end on the nail check length, and the effects of nail diameter, prehole for nail driving, and nail driving slope on the nail withdrawal resistance, by the static test of universal testing machine. The test specimen were Japanese cedar (Cryptomeria japonica D. Don.) boards grown in southern district of Korea, and the nails for test were 2.02～4.82 mm in diameter. After nail driving, the back face checks of test boards were longer than the surface checks. The optimum nail diameter without checks or loss of nail withdrawal resistance were below 10% of board width and the optimum driving distance from end of boards were ten multiple of nail diameter. The relation between nail diameter (x) and withdrawal resistance (y) was linear and the regression formulae for Japanese cedar board was y = 8.66x + 7.6 ($R^2=0.978$). As both of the prehole diameter and driving slope were increased, the withdrawal resistances were significantly decreased.

Nail withdrawal tests were conducted on clear wood of radiata pine. Nails were driven into the earlywood and latewood zones of each specimen, and nail withdrawal tests were then performed. Nail withdrawal loads were strongly dependent on earlywood and latewood and on nail position. The average load values for nail withdrawal in both the tangential and longitudinal directions were higher for latewood than for earlywood. Linear and nonlinear regression analyses of nail withdrawal load with specific gravity showed no discernible differences. Good correlations were obtained between nail withdrawal load and specific gravity.

The differentiation of nail matrix and fine structure of matrix cells were studied with light and electron microscope using specimens from nails of thumb finger in Korean fetuses 14 to 24 weeks old. Fetal nail matrix consisted of two horizontal layers, thicker ventral and thinner dorsal matrices, originating from invagination of epidermis in proximal nail field. Matrix being generally thicker in its distal region than the apex became gradually thickened with increase of the fetal age. Each matrix consisted of single layer of basal cells and multiple layers of squamous cells which are arranged close to and parallel to the central axis of the nail mairix. The process of keratinization of fetal nail matrix was noted to be occured concurrently in the ventral and dorsal matrices along the central axis of matrix toward distal and dorsal direction. Squamous cells became matured with accumulation of tonofilaments, increase of keratohyalin granules, discharge of membrane coating granules, and narrowing of intercellular spaces, thickening of plasma membrane and finally being transformed into horny cells of nail plate. Horny cells of nail plate filled with fibrous elements in the electron dense amorphous substance. These findings of keratinization process of fetal nail matrix appeared to be similar to those of keratinization in epidermis and inner root sheath of the hair. In the nail matrix, however, corresponding region to the keratogenous zone of growing hair follicle was not observed. Vacuolated squamous cells of nail matrix seen on light microscopy was considered to be artefactual product, but squamous cells with condensed small nuclei rarely found adjacent nail plate was considered to be one of the squamous cells with unknown function. Proximal end of nail plate was observed on dorsal surface of nail field distal to the proximal nail fold at 14 and 16 weeks old human embryos. Proximal prolongation of the proximal end of nail plate was occured with advancing fetal age and afterward 21 weeks nail plate invaded into nail matrix. Melanin granule containing cells and Merkel cells were present only on the basal layer of dorsal nail matirx.

This study was conducted with students who had experience in purchasing nail products asa result of by taking the nail design course of the department of beauty at a junior college. The purpose of this study was to provide useful information to nail companies, including the importance of product elements and effective media promotion, to support the planning and promoting of nail products for beauty major students. Means analysis, one-way ANOVA, and multiple regression analysis were conducted on detailed characteristics related to nail beauty (degree of nail management, degree of contact with nail beauty media) and considerations for the purchase of nail products. The results were as follows: For beauty major students, it was concluded that the greater the interest in nail beauty, such as degree of nail management and degree of contact with nail beauty media, the greater the interest in product quality, purpose, and safety, which are practical product elements considered when purchasing nail products. It was also confirmed that Instagram and YouTube advertising media have a significant effect on promoting nail product brands for beauty major students. As the subjects of this study comprise beauty major students in their early 20s, there is a limit to expanding and applying the conclusions of this study to general nail product consumers. Therefore, in subsequent studies, analysise of a wider range of nail product consumers should be conducted through an expanded sampling method.

Unlike nail care, nail art is a field with strong decorative elements that decorate the surface of the nail. In line with the trend of the times, which freely expresses one's personality, nail art is establishing itself as a definite and a key area in the beauty industry. Currently, design creation and technology developments are important, with the release of various nail materials and new trends that spread through mass media. Despite the great developments in the nail beauty industry, there is a lack for nail artists. Due to this fact, it is considered a necessary to combine nail art with the contemporary art styles, which have various motifs of design, and to study nail art design using them. In response, this study selected art from the Rococo era, where delicate and colorful decorative elements were at their peak, to consider the artistic styles of the time and present them in various nail designs. This study would like to expand the scope of new nail designs by suggesting colorful and feminine designs to women, who are the main customers of nail salon. In addition, the purpose of this study is to provide nail artists with basic materials that can be used in creative ideas and expressions, such as 2D and 3D nail designs, and composite nail design art, which are the art areas for nail art.

Purpose: The fingertip is the most commonly injured part of the hand and its injury frequently results in avulsion or crushing of a segment of the nail bed and fracture of the distal phalangeal bone. Restoration of a flat and smooth nail bed is essential for regrowth of a normal nail, which is important not only for cosmetic reasons but also for tactile capability of the fingertip. It is also anatomical reduction of the distal phalanx to promote patient's cosmetics and prevent nail bed deformity. Absence or no replacement of the nail plate results in obliterated proximal skin fold. When the avulsed nail plate cannot be returned to its anatomic position or when it is absent, we use a synthetic material for splinting the nail bed and alternative reductional method for distal phalangeal bone fracture, especially, instead of hardwares. Methods: From January of 2006 to June of 2009, a total of ten patients and fourteen fingers with crushing or avulsion injuries of the fingertip underwent using the artificial nails for finger splint. We shaped artificial nails into the appropriate sizes for use as fingernail plates. We placed them under the proximal skin fold and sutured to the fold proximally and to the lateral and medial edges of the nail bed or to the distal fingertip. Our splints were as hard as K-wire and other fixation methods and more similar to anatomic nail plates. Artificial nails were kept in place for at least 3 weeks. Results: No artificial nail related complication was noted in any of the ten cases. No other nail fold or nail bed complications were observed, except for minor distal nail deformity because of trauma. Conclusion: In conclusion, in order to secure the nail bed after injury and reduce the distal phalangeal bone fracture, preparing a nail bed splint from a artificial commercial nail is a cheap and effective method, especially, for crushed or avulsion injuries of the fingertip.
