On this study, we have observed the change of the gel nail morphology as the time elapse and measured the surface roughness/volume, moisture content/purcutaneous moisture vaporizing amount of the nail surface before gel nail treatment and after gel nail removing of the 100%acetone remover, 5%acetone remover and 0%acetone remover and the avocado non acetone remover for the comparison of the effect on the nail surface and the degree of the removing of the gel nail of the removers as the acetone contents. The removing ability were the order of 100%acetone remover, avocado non acetone remover, 5%acetone remover and the 0%acetone remover. There were no statistical significance difference in the nail surface roughness comparision before and after gel nail removing in 5%acetone, 0%acetone and avocado non acetone, and there was no statistical significance difference in the nail surface volume comparision before and after gel nail removing in 0%acetone. We measured the moisture content of the nail surface and the purcutaneous moisture vaporizing amount before gel nail treatment and after gel nail removing, resulted that, the decrease of the moisture content of the nail surface after removing the gel nail is the minimun and the increase of the purcutaneous moisture vaporizing amount of the nail surface after removing the gel nail is the minimun at the case of 0%acetone. In conclusion, 5%acetone remover and 0%acetone remover is possible to use as the gel nail remover and they had revealed that there was the least harmful effect on the nail. We hope that this study is utilized to the development of the non acetone remover and the basic research of the nail beauty industry.

To treat a kind of nail damage, this study proceeded with gel polish procedure oriented to 19 women in their twenties and thirties, dividing into three experimental groups, such as the A group with non-treatment (n=6), the B group taking Nutritional Convergent supplement (n=6), and the C group simultaneously taking Nutritional Convergent supplement and Nail Convergent Strengthener (n=7), and inquired into the superficial change of nails, changes of thickness, analysis of damage degree and satisfaction rate. The analysis shows that the C group simultaneously applied with dietary supplement and complex nail supplement presented the best result in all areas. As for the morphological changes of the surface of nails measured by the scanning electron microscope, there were definite changes as compared with the B group. According to the result, it is proved that complex dietary supplement helps to improve the thickness and the surface of damaged nails and it is reasoned that a higher effect can be expected when complex nail supplement is simultaneously used.

Excessive work intensity and stress from customers visiting nail salons due to the increase in the frequency of visits and treatments to nail salons of modern people are negatively affecting the job psychology of nail salons. Accordingly, according to the need to prepare realistic and specific measures to increase job efficacy and job satisfaction through nail treatment techniques of nail salons, the perceived job efficacy and job This study was conducted based on the research model and hypothesis for satisfaction. As a result of the study, it was found that the nail gradation technique induces the highest job efficacy of nail polishers, and it was found that the more gel manicure techniques were applied, the higher the job satisfaction of nail polishers was. Through this study, it is expected that the complex application between various nail techniques will be possible and the coordinates of the job psychology of nail beauticians will be presented, and at the same time, it will serve as basic data for improving the work environment and developing new nail treatment techniques.

As nailists do not pay much attention to development of new designs while repeating existing or variated designs, nail design is not developed further and just simple design is repeated. In this perspective, this study is to suggest nail art designs grafted on Mosaic technique using diverse objets to overcome the problems of lacking materials and design skills. For the purposes, this study analysed the concept and characteristics of Mosaic technique based on bibliographical data, Internet web-sites and previous studies, and presented 4 pieces of UV gel nail art design using diverse materials of cellophane paper, gel, hologram and stone as a convergence design. As a result, this study discovered that there is a possibility that more materials would be used and the limitation of existing nail art can be overcome through a suggestion of new convergence nail art. It is expected that further research would be conducted on satisfaction of clients in the developed skills and the result will be helpful to more sale in nail shops.

Use of UV gel for nail management have been increasing gradually. In order to develop an UV lamp necessary to UV gel, in this study, we was designed circuits of the UV-LED lamp. Power supply part that supplies constant power to the several UV-LEDs, was designed the circuit with the method of DC-DC converter. Taking into account the direction of the thumb nail and the position of the little finger nail, it was placed UV-LEDs. Input power of the power supply part was used as a battery voltage of 3.8[V]. The output voltage of the power supply part was appeared in approximately 3.1[V]. And in order to examine the state of change of the output voltage according to the amount of current consumption of UV-LEDs, after inserting of load resister, the output voltage was more than about 3.0[V] in the simulation results of the power supply part while changing the resistance value.
