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.

This study is a follow-up paper on “Development of flipped learning class model for nail beauty education” published by Seol (2022). This model was conducted from March to June 2022 for 70 students taking the “Nail color design 1” course. After 15 weeks of class, a survey of the students’ perceptions of flipped learning and their self-evaluation of goal achievement was conducted, which was composed of questionnaires using a 5-step Likert scale. 15 questions were designed to evaluate the students’ satisfaction with their experience and class operations; 4 questions to evaluate whether the class goal had been reached through flipped learning; and 9 questions to evaluate the students’ perceptions of flipped learning. As a result of applying this model to theoretical and practical nail beauty classes, it was confirmed that flipped learning helped students better understand the content and had a positive effect on learning, while the subject’s educational goals were also achieved. By evaluating the students’ perceptions of flipped learning, we may conclude that they experienced learning satisfaction and perceived the approach positively. Moreover, they have expressed a desire for additional flipped learning. This study is thus meaningful in confirming the procedure’s effectiveness by applying the flipped classroom model to theoretical and practical subjects with a focus on the nail beauty field, and showing how it achieved students’ positive perceptions and educational goals.

Flipped learning research has been applied in various educational fields since 2015 and the educational effects have been discussed in previous literature. In the beauty field, flipped learning research is insufficient; in particular, it is difficult to find research on flipped learning specifically concerning nail beauty education. The purpose of this study is to develop a model for applying flipped learning to nail beauty education which should involve practical training based on theory. Such an approach is considered effective. Data were collected and analyzed focusing on previous studies with flipped learning applied as a research method. The subject of the research is “Nail Color Design 1”, a common nail major elective subject at J college. The “Nail Color Design 1” course is a practice-oriented course in the form of theory and practical classes. Consequently, the flipped learning education model for nail beauty was designed by reflecting learners’ needs through the ADDIE instructional design model. It was applied based on the education structure of the Pre-class, In-class, and Post-class of the PARTNER instructional learning model. This study deviates from the traditional practical education model, and has educational significance as a practical model in which flipped learning is applied to nail beauty subjects and self-reflection is derived through project practice.

In the rapidly changed 21st century when the flow speed of information is so fast and the quantity of information is too much increasing, personal appearance and characteristic image-formation is highly evaluated. Nowadays personal appearance is very essential to competition and may be considered the non-linguistic expression of selfimage. The beauty action of the youth is shown to follow the object which youth want to rely on or long for and it is affected by the influence of the sociocultural elements. The purpose of this study is to identify the corelation between appearance and beauty action according to the sociocultural elements of the juveniles concerning appearance and to make an inquiry into how they pursue beauty in the restrictive bound compared with the adults. As their restrictive beauty action, the practical reflection percentage of hair-style, management of face, hand and nail control will be investigated and analyzed. Furthermore this basic material of this survey was used for the development of beauty article, cosmetics and education program. With the findings of the beauty articles in which the growing generation have a deep interest, this study provided the basic materials to the customer analysis and also the reference materials to the beauty marketing.

In order to establish a year round indoor-rearing system for Copper butterflies; large copper butterfly, Lycaena dispar, the effect of temperature on larval development and diapause was investigated. Temperature has been suggested as an important factor regulating the developmental rate, length of life, and survival rate from insect. As temperature increased, the developmental period was gradually shorten. The developmental periods of large copper larvae had a range of 11.0 days to 28.5 days at 30℃ and 17.5℃ respectively. The highest emergence rate was 94.2% recorded at 20℃. And the low emergence rate was 72.7% under 17.5℃. We investgated the sensitive stages to diapause induction in the larger copper effect of temperature and photoperiod. The experiment involves transfer of individuals from diapause averting (LD 16:8h, 25℃) to diapause inducing condition (LD 8:16h, 20℃) at various stages. Diapause was induced in 95.2% insect transferred at hatching larvae, in 15.6% of insects transferred at 2nd stadium molt, in 0% of insects transferred at after 3rd stadium molt. Percentage diapause induction increase with the length of short days and low temperature experienced. The main stage sensitive to photoperiod and temperature induction of diapause determination is the early first larval instar. The diapause induction began 14 days and ended 20 days after hatching larvae (LD 8:16h, 20℃).
