Due to the modern appearance management craze to deliver a positive image to others, beauty has been subdivided and diversified based on science and technology, and has established itself as a professional technical profession. As the national technical qualification for makeup cosmetologists is separated from cosmetologists (integrated), it is necessary to analyze the correlation with the job attitude of make-up cosmetologists at industrial sites along with verification of the effectiveness of the practical test task. Therefore, in this study, the first task, wedding (romantic), wedding (classic), hanbok, natural makeup, etc., to investigate the job efficacy and job satisfaction perceived by makeup beauticians due to beauty makeup procedures, such as wedding (romantic), wedding (classic), and after establishing a hypothesis. As a result of the study, it was found that wedding classic makeup and wedding romantic makeup treatment induce job efficacy and job satisfaction, respectively, in makeup artists. This suggests that high saturation and intense color expression have a positive effect on job attitude due to the nature of makeup work. Therefore, based on the results of this study, it is judged that future efforts are needed to update the practical makeup tasks that have doubled the effectiveness and to improve the job attitude of makeup beauticians.

Diagnosis and management of customer's skin condition is an important essential function in the cosmetics and beauty industry. As the social media environment spreads and generalizes to all fields of society, the interaction of questions and answers to various and delicate concerns and requirements regarding the diagnosis and management of skin conditions is being actively dealt with in the social media community. However, since social media information is very diverse and atypical big data, an intelligent skin condition diagnosis system that combines appropriate skin condition information analysis and artificial intelligence technology is necessary. In this paper, we developed the skin condition diagnosis system SCDIS to intelligently diagnose and manage the skin condition of customers by processing the text analysis information of social media into learning data. In SCDIS, an artificial neural network model, AnnTFIDF, that automatically diagnoses skin condition types using artificial neural network technology, a deep learning machine learning method, was built up and used. The performance of the artificial neural network model AnnTFIDF was analyzed using test sample data, and the accuracy of the skin condition type diagnosis prediction value showed a high performance of about 95%. Through the experimental and performance analysis results of this paper, SCDIS can be evaluated as an intelligent tool that can be used efficiently in the skin condition analysis and diagnosis management process in the cosmetic and beauty industry. And this study can be used as a basic research to solve the new technology trend, customized cosmetics manufacturing and consumer-oriented beauty industry technology demand.

Convergence education is one of the most frequently studied topics in the academic world as well as other various areas of the society today. The importance of convergence-based course in engineering education has long been discussed and resulted in society-wide consensus with series of attempts to apply the theory. To bring about fruitful outcome through theses efforts, we have to establish the sustainable and systematic convergence education in engineering. With this goal, we will cover the critical comprehension on the modern studies divided by three concepts(the truth, the good, and the beauty) and review the notion of "Transdisciplinarity", thereby proposing the macro goals of the convergence-based course in engineering. To realize our goals, we will suggest "Engineering aesthetics" as a convergence-based course in engineering.

This study compares the safety of nail products by reviewing domestic and foreign literature for preparing a safety management plan for reduction of human body exposure to hazardous substances that occur in nail products. We analyzed the cases of exceeding the limit value of hazardous substances. In domestic artificial nail adhesive and nail tip, toluene content was 40.3 times higher than the standard value, chloroform was 22.8 times, and antimony was 15.4 times. In developed countries, it is obligatory to provide material safety data and workplace ventilation equipment through various policy researches. However, there is no safety standard in Korea. Therefore, if the regulations for safety management should be established with each characteristic of nail product, work environment, workers, and consumers, and the awareness of hazardous substance cosmetics should be improved through development and dissemination of various educational programs, it can contribute to disease prevention and health promotion.
