A total of 45 bacterial strains were isolated from the traditional Korean soybean-fermented food, Chungkookjang. Among these strains, seven strains were selected and identified based on morphological, physiological, and biochemical characteristics, as well as phylogenetic analysis using 16S rDNA sequences. All strains were Gram-positive, aerobic, motile, oxidase-positive, rod-shaped, and endospore-forming bacteria, and produced extracellular enzymes such as amylase, cellulase, lipase, protease, and xylanase. The isolates were grown in the presence of 0-11% (w/v) NaCl. Growth was optimal at pH 6-9 and at temperatures of $30-45^{\circ}C$. According to VITEK automicrobic system tests and supplementary tests, the isolates were similar to several species of the genus Bacillus. The phylogenetic analysis of seven bacterial strains based on comparisons of 16S rDNA sequences, revealed that the strains were closely related to Bacillus species. The identification of strains that produced surfactin was also carried out, based on PCR screening of the sfp gene. Among the seven isolated strains, six yielded a surfactin-positive result with PCR.

While technologies such as the 4th revolution and artificial intelligence (AI), which create new value through the convergence of intelligent information technology, are becoming hot topics, the beauty industry is rapidly developing and combining information and communication technology to produce beauty items based on smartphones among mobile technologies. As the area of expands, YouTube is forming a network through various means of information. In particular, beauty-related YouTube videos are a field of great interest and popularity among the public. By classifying the makeup characteristics according to the emotional images shown in domestic YouTube videos by emotional image and identifying the characteristics of makeup, the needs for watching YouTube makeup videos are identified. We aim to build trust in the delivery of information about makeup. The emotional images were divided into four types: 'modern', 'natural', 'gorgeous', and cute. Among the domestic makeup YouTubers, Pony, Isabe and Shinnim, Lamuque were selected. By organizing more diverse makeup-related content systematically and creatively, we expect to have a positive influence on k-makeup not only domestically but also overseas. We aim to provide basic data for follow-up research on makeup YouTuber videos in the field of cosmetology and contribute to marketing plans for the development of the beauty content industry and establishment of promotional strategies.

This study examined differences in beauty majors' career maturity and career decision-making depending on the grade and analyzed the relationship between the career maturity with the career decision-making to present basic data for guidelines that would help any relevant field with their career consultations and education targeting those students majoring in beauty at college. A total of 336 beauty majors in the metropolitan area were selected as the research subjects. The study confirmed that the higher the grade, the greater the career maturity. The students who had a higher level of career maturity tended to be included in the reasonable career decision-making category while those students with a lower level of career maturity were determined to conduct dependent decision-making. In terms of the career decision, the students in the higher grades were reasonable enough to make decisions logically because they collect various information through systematic stages but when it comes to the students in the lower grades, they were divided into the intuitive type that would reach a decision through emotional self-recognition depending on how one feels at this moment or what situation one is going through as well as the dependent type that would let people or environments influence one's decision-making. The grades of the students tended to cause differences in the career maturity and the career decision-making, and the significance between the two variables was proven. If the relevant fields carry out systematic grade-focused programs and career guidance not only to improve the career maturity of even the lower graders but also to encourage the students to make reasonable decisions, such programs and career guidance will be a help when the students try to determine a career.

In this study, we applied 15% glycolic acid peeling agent and 30% glycolic acid peeling agent to the dorsal skin of mice and analyzed the oil content, moisture content, and pH value of the skin before and after test using cutometer. Ultrastructure for changes in the epidermis of mice were observed under a dermoscope and a scanning electron microscope before and after test. When using 15% glycolic acid peeling agent, the changes of moisture content was measured 74.67 AU for the normal control group and 70.21 AU for the experimental group, the oil content was 13.49 mg/$cm^2$ for the normal control group before test and 8.25 mg/$cm^2$ after test, and the pH value was 6.70 and 5.36 before and after test, respectively. When using 30% glycolic acid peeling agent, the moisture content was measured 74.46 AU for the normal control group before test and 53.50 AU for the experimental group after test, the oil content was 13.82mg/$cm^2$ and 5.70 mg/$cm^2$ before and after test, and the pH value was 6.45 and 4.58 before and after test, respectively. As such, it was found that the changes of moisture and oil content on the skin rely on the concentration of peeling agent and the degree of exfoliation of keratin. The surface of stratum corneum of mice with application of 15% glycolic acid peeling agent was relatively smooth and the exposed cellular surface of keratinocyte had some wrinkles. The surface of stratum corneum of mice with application of 30% glycolic acid peeling agent was smooth. No wrinkles were observed under high-resolution scanning electron microscope.

The purpose of this study was to compare and analyze the differences and satisfaction of each purchase behavior by classifying cosmeceutical and medical cosmetics. A total of 861 questionnaires were distributed to males in their 20s to 50s (from 1 march 2017). A total of 446 respondents with experience using cosmeceutical cosmetics and medical cosmetics used as the final analysis material. According to the study, the term recognition for cosmeceutical cosmetics and medical cosmetics was very low. The differences in each purchase behavior were not statistically significant. but cosmeceutical cosmetic products have been found to have a significant impact on quality, price, container design, and service satisfaction among purchase preference factors (p<0.05, p<0.01, p<0.001), In particular, it was found that satisfaction with quality was the greatest. Medical cosmetics have been found to have a significant positive (+) effect on brand image, price, and container design among purchase preference factors (p<0.01, p<0.001), It was also found to have the biggest satisfaction with the brand image. Based on the results of this study, The features of cosmeceutical cosmetics and medical cosmetics are subdivided. It has been deemed necessary to develop differentiated products according to each purchase behavior and preference.

In this study, 340 Korean women were surveyed to analyze the impact of the type of sunscreen and use status on the satisfaction of products and resale. Studies have shown that indoor activity is higher than outdoor activity, and both simple and complex sunscreen is often used to compensate for skin tone. Out of single sunscreen, sun cream was used and air cushion was used a lot. Although product usability and UV protection indices were important factors in purchasing, 30% experienced side effects while product satisfaction and willingness to repurchase were high. The recognition of safety, Effectiveness, convenience, usability, satisfaction, and repurchase were all higher than that of composite UV-blocking products, and among subcomponents of product usage recognition, the level of convenience, efficacy, usability, and safety affected satisfaction and repurchase in order. Consequently, the perception of simple UV protection products was higher when using products for UV protection, and its convenience had a significant impact on satisfaction and resale.
