The purpose of this study was to identify beauty influencer attributes on Instagram and their impact on product attitude and purchase intention and on influential difference between micro and mega influencers. The survey was conducted using a consumer survey method with a questionnaire, and the subjects of the survey were 506 women in their 20s and 30s using Instagram. The results of the study are as follows: First, a range of influencer attribute sub-factors were derived in relation to expertise, attractiveness, similarity, reliability, and intimacy. Second, the attributes highly impacted product attitude in the increasing order of attractiveness, similarity, reliability, and familiarity, with expertise having no statistically significant influence. Third, the consumer's attitude toward the product introduced by the beauty influencer had a significant impact on their purchase intention. Fourth, it was shown that there is no difference in attributes according to the influencer's number of followers. Fifth, the number of followers of the beauty influencer had a partial impact on attitude and purchase intention. A limitation of this study is that age and gender samples are narrow, but it is nevertheless meaningful to explore this topic in the absence of research on beauty influencers. It is believed that these findings will serve as a foundation for the development of beauty influencer marketing strategies on Instagram.

Background: The safe use of medication in children is important, as it can have significant implications for their health and wellbeing. Parents or caregivers play a crucial role in the medication administration process. Therefore, this study would evaluate the needs and current status (knowledge, attitude, and practice) of caregivers for children on the safe use of medication. Methods: We conducted questionnaires on 150 caregivers with children under nine years old and asked about their knowledge, attitude, and practice regarding the safe use of medication and their needs. Each question was conducted on a 5-point scale. Results: Of the 150 respondents, 128 were women, 75 were in their 30s, and 63 were in their 40s. Among them, 29 parents answered that they had been educated about the safe use of medicines, and 26 (84%) were satisfied with the education. Knowledge, attitude, and practice assessments on drug safety use (mean±SD) were found to be 3.83±0.44, 3.67±0.38, and 3.53±0.45, respectively. There were significant differences between the educated group and the uneducated group in knowledge and practice, not attitude. Conclusion:To provide appropriate education to caregivers of pediatric patients is necessary to ensure the safe and effective use of medication in children. Moreover, appropriate education can improve caregivers' understanding of medication use and lead to proper administration. Therefore, it is imperative to develop educational materials and strategies for medications that incorporate both specialized knowledge and practical applications for pediatric patients.

This study conducted a survey with 203 single households among men and women in their 20s to 40s who were living in metropolitan areas from October 6 to November 4, 2012 in order to investigate the dietary attitude of the single households. The ratio of single households who had three meals a day regularly was 2.85 points, which was lower than the normal level, and it turned out that those in their 20s and 30s had meals more regularly than those in their 40s did (p<0.001). As for the irregular meal time, most were breakfast (85.9%), and it turned out that they often skipped meals mostly because they did not have time to eat and (41.7%) or because that bothered them (26.0%). 62.6% of the single households did overeating and most of them (39.4%) did overeating because of their irregular meals. Of the single households, women or persons who had lived alone for less than 3 years or more than 7 years cooked at home, more often (p<0.05), and most of them (42%) cooked noodles, easy to cook, but women cooked Korean food-based homemade food such as rice (31.7%) or soup and stew (21.2%), often (p<0.05). It turned out that 36.9% of the single households often ate out about two to three times a day, and as for their favorite eating-out menus, 39.4% were Korean food, followed by Western food (23.8%), flour-based food (13.5%), fast food (9.8%), Chinese food (7.3%) and Japanese food (6.2%). Lastly, as for inconveniences when they ate out, most were the 'price' (22.8%), followed by 'too much amount of food for one person' (20.2%) and 'limitations in menu selection' (19.2%). As a result of this study, it appeared that the single households had an irregular dietary life, often did overeating and often ate out, so it is judged that it would be necessary to develop a variety of nutritionally-balanced HMR food and eating-out menus in a reasonable price range for their healthy dietary life.

This study was designed to find out how the sociocultural attitudes toward appearance, BMI and body image of adult women affect their self-esteem. A questionnaire was prepared in the survey and a total of 456 adult women were selected by way of stratified random sampling. The research findings are as follows: 1. The sociocultural attitudes toward appearance were shown in two factors of 'internalization' and 'awareness'. The body image was shown in three dimensions of 'care for appearance', 'concern about weight', and 'appearance attractiveness'. 2. Internalization, recognition, and BMI influenced on 'care for appearance'. 'Concern about weight' was affected by internalization and BMI. Appearance attractiveness was affected only by BMI. 3. Adult women's self-esteem was influenced by appearance attractiveness, internalization, and care for appearance. 4. The behaviors of appearance management were differed according to the sociocultural attitudes towards appearance. Therefore, adult women form a higher degree of self-esteem is formed when they accept what they are regardless of their actual BMI and when they evaluate their body positively.

This study developed an antimicrobial hydrogel to control Listeria monocytogenes in Yukhoe (Korean beef tartare). Four hydrogels (hydrogel 1: 5% alginate+1% chitosan+0.2% $CaCl_2$, hydrogel 2: 1% ${\kappa}$-carrageenan+1% chitosan, hydrogel 3: 2% ${\kappa}$-carrageenan+1% $CaCl_2$, and hydrogel 4: 2% ${\kappa}$-carrageenan+3% $CaCl_2$) were prepared. The hydrogels then absorbed 0.1% grapefruit seed extract (GSE) and 0.1% citrus extract (CE) for 30, 60, 120, and 240 min to be antimicrobial hydrogels. To select the most effective antimicrobial hydrogel, their swelling ratio (SR) and antilisterial activities were determined. The selected hydrogel ($2{\times}2cm$) was then placed on surface of beef (round; $3{\times}3cm$), where L. monocytogenes (ca. $10^6CFU/g$) were inoculated, and the cell counts were enumerated on PALCAM agar. Among the hydrogels, the SR of hydrogel 1 increased with absorbing time, but other hydrogels showed no significant changes. Antimicrobial hydrogel 1 showed higher (p<0.05) antilisterial activity than other antimicrobial hydrogels, especially for the one absorbed the antimicrobial for 120 min. Thus, the antimicrobial hydrogel 1 absorbed antimicrobials for 120 min was applied on raw beef at $4^{\circ}C$, and reduced (p<0.05) more than 90% of L. monocytogenes on raw beef. These results indicate that antimicrobial hydrogel 1 formulated with 0.1% GSE or 0.1% CE is appropriate to improve the safety of Yukhoe by reducing psychrotrophic L. monocytogenes cell counts on raw beef.

This study establishes the initial data to develop a well-fitted underwear pattern by categorizing and analyzing torso types based on body measurements of women in their 50s and 60s. The results are as follows: First, the statistical assessment on the body measurements showed meaningful differences among age groups in twenty seven items (except for bust breadth, hip width armscye depth, hip depth, neck base circumference, armscye circumference, chest circumference, hip circumference, bishoulder length, shoulder length, front interscye, back interscye, weight and inclined angle of left shoulder). Women in their early 50s and late 60s (respectively) showed the highest values in height and depth. Second, there are five body factors according to the results of the factor analysis: Factor 1 (circumference, width, and depth of upper body measurements) - the degree of body depth and obesity, Factor 2 (height and vertical length) - The vertical torso length, Factor 3 - the size of shoulder, Factor 4 - the vertical upper body length, and Factor 5 - the size of shoulder angle. Third, the results of the cluster analysis showed that there are four distinctive body types. The largest number of the study subjects was related to Type 3 (30.69%), followed by Type 2 (26.78%), Type 1 (25.84%), and Type 4 (16.69%), respectively. For distribution of age groups by body type, Type 3 was the most common among the 60s group while Type 2 appeared most frequently among the 50s.

[Purpose] The purpose of this study was to investigate the effect of diet plus exercise training and detraining for 12 weeks on body composition, aerobic performance, and stress-related variables in obese women. [Methods] Twenty-five women in their 20s-40s with 30% body fat and body mass indices above 25 kg/m² were divided into HR_LT (heart rate at lactate threshold) and HR_LT + 5% groups. Dietary intervention of 70% recommended dietary allowance (RDA) and exercise treatment composed of aerobic exercises on a bicycle (30 min) and treadmill (30 min) were then performed. These interventions were performed three times a week for 12 weeks. [Results] Dietary intake was significantly decreased, while daily activity significantly increased within the 12-week intervention period, and this effect was sustained after 12 weeks of detraining. Exercise training based on dietary intake and daily activity presented a significantly decreased weight and % body fat, improvement of aerobic performance, and a significant increase in heart rate variability (HRV) (e.g., average of all RR intervals and the square root mean squared differences of successive RR intervals) as stress-related variables. It was also confirmed that the improvement of body composition and stress-related variables were maintained even after detraining. [Conclusion] Our results suggest that 70% RDA of dietary intervention and exercise training corresponding to HR_LT and HR_LT + 5% for 12 weeks were effective in improving body composition and aerobic performance, and relieving stress. In particular, enhanced HRV persisted for up to 12 weeks after the end of exercise training in obese women.

The purpose of this study presents bra pattern using the 3D measurements of the upper body subject to women in their 30's. Brassieres available in the market are mostly designed for straight body shape and many women seem to have experienced bearing discomfort in a great extent as they grow older. Brassieres should be designed to cover diverse body types and the accurate measurement of body type and breast shape is needed to accomplish that. As for the study method, 3D human body types were analyzed with RapidForm 2006, and the upper-body types and breast shapes were statistically classified through technical statistics analysis, cluster analysis, t-test, variance analysis, and cross analysis. The wearing tests went through the comparison of the brassieres of three makers in the market and the experiment brassieres(first and second) and then the evaluations were made by the subjects, the outer appearance assessment by experts, and 3D measurements. The results of this study showed that the evaluation of experiment brassieres was excellent in every item, and the significant difference was found out particularly in the items of pressure, rear center, front center, breast underneath, adequate level by wing, and adequate level by armhole. According to the results of 3D evaluation, experiment brassieres had a highest point in fitness with no physical pressure at the wing part and no overall deviation at the cup part.

The purpose of this study is to identify the differences between married women's dissatisfaction towards imported and domestic clothing and to test the role of socioeconomic variables on dissatisfaction. Two-piece formal suit was selected as the item, and country of origin of imported suit was not controlled. Sample selection criteria included married women living in Seoul, Korea, between ages 30-59. The data were analysed using factor analysis, paired t-test, and one-way ANOVA. The results indicate, in the Korean clothing market, both international and Korean marketers should be prudent with their price policies and should implement differentiated marketing strategy based on their target market's demogrophic profile. Higher dissatisfaction towards domestic clothing in terms of most factors, under the rapidly globalizing market environment suggests the Korean marketers will be forced to face full-scale harsh competition from international marketers.
