There is likely to be a fit problem when women aged in their 30s-40s purchase down-age clothing from brands that target women in their 20s. To identify the part of the lower body that causes the fit problem, the sizes and types of lower body of women in their 30s-40s were compared with those of women in their 20s. The data for this study was from the 2010 Size Korea survey of body measurements of 1675 female adults in their 20s-40s. To examine differences in the average sizes of the lower body between women in their 20s and 30s-40s, descriptive statistics and t-tests were conducted. Factor and cluster analysis were used to classify body types by age groups. On the whole, compared to women in their 30s-40s, women in their 20s were found to be higher for all height items and smaller for size, thickness and width items. The result of the Glycemic index analysis showed that the body type of women in their 20s was generally larger than that of women in their 30s-40s. In addition, women in their 20s had a large drop value compared to those in their 30s-40s, whereas flatness of body cross section was bigger in the group of women in their 30s-40s. Four factors related to the lower body type of female adults in their 20s-40s were identified in the factor analysis, and three categories of body type were identified by cluster analysis. A Type 1 individual had abdominal obesity and chubby lower limbs, Type 2 had short legs and slightly chubby lower limbs, and Type 3 had long legs and a skinny lower body. A significant number of women in their 30s-40s were included in the Type 1 group, which was the least common category for women in their 20s.

In this study, the Korea National Health and Nutrition Examination Survey in 2016 examined the nutrient and food intake of women in their 20s and 30s according to the number of meals a day, and the results were as follows: The study included 256 women in their 20s and 474 women in their 30s. Women in their 20s and 30s ate two meals a day, indicating that the notion of three meals a day was gradually changing to two to three meals a day. Those in their 20s and 30s who eat one, two or three meals a day were consuming less than the estimated energy requirement of the DRI for Koreans 2015. The vitamin A and C were eating less than the recommended intake in all meals. In the case of minerals, calcium was taken less than the recommended intake in all meals, but sodium was taken above the goal intake in all groups. Women in their 20s and 30s must reduce their intake of saturated fatty acids and sodium, and increase their intake of vitamins A, C, calcium, and potassium. Women in their 20s and 30s drank a lot of coffee, ate baechu-kimchi and rice frequently per week.

Women in their 30s and 40s, who are at the center of "ageless" and "down-aging" consumer trends, are likely to encounter problems with fitting and size conformity when they wear casual clothes targeting women in their 20s. Hence, differences in upper body sizes and body types between women in their 20s and women in their 30s and 40s were analyzed. The data for this study was from the 6th Size Korea survey of body measurements of 1,675 female adults in their 20s-40s. SPSS 21.0 for Windows was used for analysis of the collected data. To examine differences in average upper body size between women in their 20s and women in their 30s and 40s, descriptive statistics and independent sample t-tests were conducted. Factor and cluster analyses were used to classify body types by age groups. Comparing direct measurement items showed that women in their 20s tend to have higher average values for most height-related items-including body height-and lower average values for circumference, thickness, and width than women in their 30s and 40s. Factors in determining the upper body shapes of women in their 20s to 40s were narrowed to five; through a cluster analysis, upper body shapes of women were classified into three body types as follows. Type 1 women are shorter and thinner with small frames; Type 2 women have the highest vertical values for their upper bodies and average values for obesity-related categories of circumference, thickness, and width. Type 3 women are the shortest and has the highest body mass index (BMI), verifiable as obese. By analyzing differences in body type distribution according to age groups, it was found that more than 90% of women in their 20s belong to Types 1 and 2. On the other hand, most women in their 30s and 40s are identified as Type 3.

In order to improve the problems with obese women's ready-to-wear by age range, this study surveyed the actual clothing purchase and wearing of women in their 20s and 30s with normal and obese body types, and compared and analyzed their satisfaction with ready-to-wear by age and body type. First, for normal body types, both women in their 20s and 30s use department stores the most. Meanwhile, obese women in their 20s make most of their purchases at internet shopping malls, while those in their 30s mostly go to department stores. For criteria for purchasing clothing, normal women both in their 20s and 30s value design most whereas, obese women put size and fit before design regardless of their age. Normal women in their 20s and 30s both were most unsatisfied with standardized design because they could not find designs they wanted. Obese women in their 20s and 30s also showed disapproval of unvaried sizes, indicating a distinct difference in body types and age. As well, the study found that both normal and obese women wear casual style the most, followed by semi-formal style. Also, regarding the images they were seeking when wearing clothing, the normal women wanted to look fashionable, while obese women wanted to look slim, regardless of age. Both body-type groups generally like preferred semi loose-fits the most, followed by tight-fit. They however, dislike relaxed loose-fitting.

This study investigated the divorce and post-divorce adjustment of divorced men and women in their 20s and 30s and explored the sex differences. For this empirical analysis, the data was collected from 230 divorced men and women in their 20s and 30s who lived in the Seoul metropolitan area from Sep. 23rd to Oct. 20th, 2002. The questionnaire for the survey dealt with demographic information and other scales. The major findings of the research project were as follows: First, although men and women experienced a similar level of pre-divorce conflicts, women were more likely to want to divorce. Second, although women had worse physical and psychological condition and more difficult problems than men after divorce, women more readily accepted their divorce reality than men. Divorce was not the best but the second best way to escape from a bad marriage for women. The results of the current research are expected to contribute to the pre-marital preparation and divorce adjustment programs.

The purpose of this study is to do an in-depth examination of Korean women in their 30's on the characteristics of their online fashion shopping, clothes-wearing, and presentation. In-depth interview and quantitative analysis were conducted as study methods. Results of this in-depth analysis showed that the factor with the most significant influence in their lifestyle was "childbirth." Childbirth was a major factor during fashion shopping and clothes-wearing. Also the results showed that the reason they used online shopping was for convenience, efficiency, rationality, pursuit of information, variety, and hedonism. In particular, women in their 30's had a higher motivation for efficiency and rationality compared to those in their 20's, and of those women, married working women showed the highest preference for fashion soho malls. Meanwhile, full-time homemakers, who pursued rationality, used open markets to search for fashion items based on price. Furthermore, the factors that women in their 30's considered during online shopping were price, design, purpose or situation for wearing the clothing, respectively. Compared to the women in their 20's, they emphasized recommendation, product properties, credibility, economy more than women in their 20's. Factors such as marriage and childbirth were more influential than occupation. Meanwhile, the factors that women in their 30's considered for wearing and presentation were time, place, and occasion(TPO), which all showed high importance in in-depth interview and quantitative analysis. Other factors were 'suitable image to self' and 'covering up body figure.'

Objective: This study aimed to analyze somatotype characteristics of the women of 20's, 30's 40's and 50's and thus to provide the basis for developing pants patterns by the age groups. Background: Despite many previous researches for the somatotype characteristics of adult women, few studies have considered age groups. Method: The data of the $5^{th}$ anthropometry by Size Korea were analyzed for the purpose. The 32 direct body measurements and the 32 indexes of 2,213 women aged 20~59 were analyzed. In order to compare somatotype characteristics among the age groups, an ANOVA and a Tukey test were used. Results: The women in 20's were the tallest among the age groups, and had the smallest waist circumference and hip circumference. Their waist breadths were also the narrowest. They had a slim and long body type but their calves were relatively thick. The 30's women were smaller, shorter with the height and length items than the 20's were. They were bigger, wider and deeper with the circumference, breadth and depth items than the 20's were and they were heavier. On the other hand, their hip circumference and crotch length were in the same group as the women in 20's. The crotch length(omphalion) of the 40's women was the longest among all the age groups and the crotch length(natural indentation) of the 40's women was in the same as the women in 50's. The women in 50's were the smallest and heaviest among all the age groups. The difference between their hip circumferences and waist circumferences was the smallest. They had an obese abdomen and sagged hips. Conclusions: The somatotype characteristics of the age groups were significantly different, and thus it is suggested to develop skirt and pants patterns for each age group. Application: The skirt and pants patterns for the somatotype characteristics of the women by age groups will be developed through the body feature data of this study.

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 purpose of this study was to identify imported apparel selection behavior according to Mongol women's conspicuous consumption orientation. A self-administered questionnaire was used for data collection. First, factors of conspicuous consumption orientation were high price and luxury brand, fashion style, altruism, prestige, and brand. Mongol women were segmented into the price and prestige pursuit group, the fashion and brand pursuit group, the altruism pursuit group, and the conspicuous consumption retard group. Second, factors of motivating the selection of imported apparel were value, symbolism, and aesthetics, and Mongol women considered the aesthetics of imported apparel important. Married Mongol women in their 30's chose imported apparel because of its symbolism. More married women selected imported apparel because of its value and more educated women selected imported apparel because of its aesthetics. Women with higher apparel expenditure selected imported apparel because of its value and symbolism. Quality, diversity, and the fit of imported apparel were the selection criteria for Mongol women and they were satisfied with the quality, diversity, and fit of the imported apparel. Brand awareness was very important when selecting imported apparel but the women's satisfaction level was significantly low. Third, more women in their 30's, unmarried, or with a lower educational level were found in the price and the prestige pursuit group, and the price and prestige pursuit group and the altruism pursuit group selected imported apparel for its aesthetics. More unmarried women in their 30's with a higher educational level were found in the fashion and brand pursuit group and selected imported apparel for its value, symbolism, and aesthetics. More unmarried women in their 20's with a higher educational level were found in the altruism pursuit group, but unmarried women in their 20's with a lower educational level were found in the conspicuous consumption retard group.
