Background: 20(S)-Protopanaxadiol (20S-PPD) is a fully deglycosylated ginsenoside metabolite and has potent dermal antiaging activity. However, because of its low aqueous solubility and large molecular size, a suitable formulation strategy is required to improve its solubility and skin permeability, thereby enhancing its skin deposition. Thus, we optimized microemulsion (ME)-based hydrogel (MEH) formulations for the topical delivery of 20S-PPD. Methods: MEs and MEHs were formulated and evaluated for their particle size distribution, morphology, drug loading capacity, and stability. Then, the deposition profiles of the selected 20S-PPD-loaded MEH formulation were studied using a hairless mouse skin model and Strat-M membrane as an artificial skin model. Results: A Carbopol-based MEH system of 20S-PPD was successfully prepared with a mean droplet size of 110 nm and narrow size distribution. The formulation was stable for 56 d, and its viscosity was high enough for its topical application. It significantly enhanced the in vitro and in vivo skin deposition of 20S-PPD with no influence on its systemic absorption in hairless mice. Notably, it was found that the Strat-M membrane provided skin deposition data well correlated to those obtained from the in vitro and in vivo mouse skin studies on 20S-PPD (correlation coefficient $r^2=0.929-0.947$). Conclusion: The MEH formulation developed in this study could serve as an effective topical delivery system for poorly soluble ginsenosides and their deglycosylated metabolites, including 20S-PPD.

This study aims to investigate the actual condition of wearing leggings and the preferred design of down-aging women in their 30s and 40s who have young sensibility, but are starting to enter a middle-aged body type. By analyzing the problems experienced when wearing leggings in this age group, this study intends to provide basic data for the development of a middle-aged female leggings pattern with an improved fit. Therefore, a survey was conducted on 214 women in their 30s and 40s. The results of the survey are as follows. Among down-aging women who want to look younger, leggings are becoming an essential item, but most leggings brands are producing leggings with patterns suitable for women in their 20s. The results of this study also showed that down-aging women in their 30s and 40s mainly purchase and prefer body-fitting leggings. However, they are experiencing discomfort due to 'Y-zone accentuate', 'undergarment accentuate', 'cloth stucking', and 'waist band curling and tightening'. The results indicate that women in their 30s and 40s, who are starting to change to a middle-aged body type, have fit problems. Women in their 20s generally prefer functions that improve the body line, while those in their 30s and 40s prefer functions that improve movement and cover problems caused by the abdomen and the Y-zone area. Therefore, when designing leggings for down-aging women in their 30s and 40s, based on body-fitting leggings, a material with excellent elasticity must be selected. Also develop patterns that solves 'Y-zone accentuate', 'undergarment accentuate', 'cloth stucking', and 'waist band curling and tightening' problems.

The number of North Korean refugees residing in the Republic of Korea (South) has reached 17,000, and this number is expected to exceed 20,000 (North Korean Supporter's Association, 2009). Refugees have developed improper dietary habits while hiding and escaping North Korea. They have also developed preferences for exotic food. This thesis attempts determine the changes in Korean food. This study also describes the view on South Korean food by North Korean refugees. According to our survey, women refugees had better dietary habits than men. Moreover, women and those in their 40's showed a tendency to choose food based on quality over quantity. Both men and women refugees responded that they cook food based on North Korean recipes. Those who view their current financial status as average or higher stated that South Korean food is tastier than North Korean food. Those whose financial status among North Koreans was average or higher when they lived in North Korea appreciated the splendor and beauty of South Korean food more. The results of this study are expected to assist in determining the differences in dietary habits between those from the North compared to Koreans living in the Republic of Korea. Therefore, studies between South and North Korean food should continue.

This research attempted to examine whether there were differences in preference for the shoes according to fashion lifestyle and age by conducting survey on 200 women of 20s and 40s among the adult women who were expected to have interest in not only functionality but also aesthetic aspects of shoes. First, the results of comparing the preferences according to fashion lifestyles showed that those who pursued practical group preferred loafer, strap shoes, and baggy boots, indicating that they preferred low and comfortable shape of shoes which are easy to put on/take off and easy to coordinate with any clothes. Those who pursued personality group and ostentation group were more sensitive to fashion than practical group preferred high heel shoes, which could express their own personality, it would be great to have various designs by reflecting the trendy materials and details focusing on pumps, strap and walker boots which can express individuality and supplement the body shape and height as matching to the trendy clothes. Second, as women in 20s have tendency to show more preference of a certain trendy shoes shape than women in 40s, the shoes designs for 20s should focus on certain types of shoes preferred by them by varying materials and details, rather than having various designs. However, it would be great to show various designs for the shoes for 40s. Most of the 20s are the individual and complex fashion-seeking types while the 40s have the most of practical fashion-seeking type and the least of individual fashion-seeking type.

Purpose - Among potential marketing strategies, the most efficient method to encourage purchase intention is through sales promotions. Sales promotions also serve to enhance customer satisfaction, which is closely related to the incidence of repurchases. Therefore, the success of retail stores greatly depends on the effectiveness of their promotional activities. The present study aimed to obtain the necessary information for apparel stores to establish more effective promotional activities. To this end, the study's specific research questions were to examine 1) consumer satisfaction with the recent sales promotions of retail apparel stores, 2) the levels of consumer preferences for different types of sales promotions (cash discounts, promotional gifts, prize drawings, discount coupons, stamp cards, or mileage cards), and 3) the differences in purchase intention according to preference levels for different types of sales promotions. Research design, data, and methodology - The research employed a descriptive survey method using a self-administered questionnaire. The sample consisted of 700 men (n=234) and women (n=466) ranging in age from their 20s to their 50s and residing in the Seoul area. Data were analyzed through methods including factor analysis as well as Cronbach's α coefficients, the t-test, ANOVA, and the Duncan test. Results - Differences among consumer preferences were identified for each type of sales promotion according to the purchase amount and the customer's age. In relation to purchase amounts below 500,000 won, participants in their 50s have lower preferences for price discounts than those in their 20s or 30s, whereas participants in their 40s or 50s have lower preferences for stamp cards and mileage cards than those in their 20s. When the purchase amount is greater than 500,000 won, housewives have higher preferences for promotional gifts than respondents with other occupations. However, no gender differences were found with regard to preference levels for the different types of sales promotions. Respondents generally exhibited mediocre satisfaction with the sales promotion events of retail apparel stores. They also expressed negative opinions about sales promotions when such promotions lead to high prices, as well as dissatisfaction with the poor quality of promotional gifts. It was also found that, regardless of the purchase amount, the groups with higher preferences for discount coupons and mileage cards displayed higher purchase intentions. Only when the purchase amount is greater than 200,000 won did the group with higher preferences for lottery system promotional gifts express higher purchase intentions. On the other hand, for all purchase amount sizes, there were no differences in purchase intentions according to preferences for cash discounts, promotional gifts, or stamp cards. Conclusions - The results revealed that greater effort must be devoted to enhancing consumers' satisfaction levels with the promotional activities performed by apparel retail stores. The results also showed that it is necessary to differentiate among sales promotion strategies according to preference levels for different types of sales promotions, purchase amounts, and target consumer ages.

With increasing concerns about environmental issues that can result from apparel and textile disposal, the recycling methods for discarded fashion products have gained significant attention. As the influential drivers of consumer purchasing and consuming behaviors, fashion innovativeness and fashion involvement can play important roles in forming consumer attitudes toward apparel recycling. The purpose of this study was to (1) investigate consumer attitudes toward three different methods of apparel recycling including resale, reform, and donation, (2) examine the effects of fashion innovativeness and fashion involvement on consumers' apparel recycling attitudes, and (3) identify gender difference in the relationships among fashion innovativeness, fashion involvement, and recycling attitudes. Using a web-based survey, data were collected from 281 Korean consumers who were in their 20s and 30s. Overall, both male and female consumers revealed the most favorable attitudes toward apparel recycling through donation, followed by reform, and resale. The findings suggest that consumer traits, such as fashion innovativeness and fashion involvement, are important factors predicting male consumers' apparel recycling behaviors. Those male consumers who perceive fashion as important were more interested in apparel recycling than those males who put low importance on fashion. Male fashion innovators were less likely to recycle their unused and old apparel items. Further studies identifying antecedents of female consumers' attitudes toward apparel recycling are warranted.

This study is a cross-sectional survey study aimed at collecting basic data for the development of a program to cultivate a positive attitude toward dementia among people caring for dementia patients. For this study, data were collected from March 1 to March 7, 2022 as a structured questionnaire, and 232 study participants were in their 20s to 60s. The collected data were derived from chi-square test, t-test, and simple regression analysis using the spss 18.0 program. As a result of the analysis, women had higher treatment knowledge for dementia than men, men had higher attitudes toward dementia than women (p<0.01), and people living with dementia patients had higher attitudes than those who gave birth (p<0.01). Attitudes toward dementia were more positive in the family than those with dementia patients (p<0.01). Dementia-related knowledge consists of disease knowledge, treatment knowledge, and nursing knowledge, of which only positive dementia attitude affects dementia treatment knowledge (t=5.29, p<0.01). Based on these results, it is suggested that the provision of accurate knowledge about dementia treatment should be planned first as a nursing program for dementia patients.
