네일미용사의 RN(Return to natural Nail)을 활용한 내향성 발톱관리 프로그램 개발

he purpose of this study is to develop an ingrown toenail care program using nail technicians’s RN, and to provide proper usage methods and standards by developing a program to be utilized in ingrown toenail care, a part of problematic foot care. This study employed a modified Delphi technique to develop the ingrown toenail care program, conducting tests on 204 items across three areas-hygiene, procedure, and follow-up care-with a panel of 12 experts. Data analysis was conducted with the use of the SPSS(ver. 21.0) program for descriptive statistics, measures of central tendency, and validity analysis. The Wilcoxon signed-rank test was conducted to verify the homogeneity of the 2nd and 3rd questionnaire survey results. The findings are as follows: First, analysis of open-ended questionnaire showed expert consensus and high validity for 5 items. Second, in the 2nd Delphi analysis, the experts reached consensus on the mean, standard deviation, agreement, and convergence, indicating high validity. The Content Validity Ratio(CVR) was generally valid, excluding 2 items. Third, the 3rd Delphi analysis results also showed general validity, excluding 2 final items. Fourth, the Wilcoxon signed-rank test confirmed consensus(p＜.05). Based on these findings, this study provides foundational data for standardized ingrown toenail care using the RN nail traction device. It is expected that the program can enhance applicability in education and practice, extending its use beyond the beauty field to the medical field.
