This paper identified the values and awareness of Koreans in 20s regarding Hanbok, the traditional clothing of Korea, and proposed an approach to promote the traditional clothing culture. The subject of the survey were male and female Koreans in their 20s who wear modern street clothes in places people frequently visit including in the metropolitan area and Chungcheong-do as well as those who wear Hanbok in Seoul and Jeonju, Jeollabuk-do. In accordance with the analysis of the survey, Koreans in their 20s rented Hanok rather than buying it. The respondents wore Hanbok for events, festivals or national holidays or while travelling. Elements to improve in Hanbok rental services were designs, materials, washing and stains. The decision factors for renting Hanbok were 'personal tendency' and 'advice from an expert.' While Koreans in their 20s had a positive awareness of Hanbok, they thought it was difficult to buy, rent and put on Hanbok and that it was not comfortable to wear. There was not sufficient opportunity and means to wear Hanbok due to insufficient accessories or shoes to match. On the basis of the analysis of the survey results, the following approach was proposed for the development of the traditional clothing culture. First of all, develop traditional clothing designers who can satisfy the personalities of Koreans in their 20s. It is necessary to develop experience-focused and participatory programs that provide systematic education regarding traditional clothing to pass down this tradition. In addition, it is necessary to create a social and cultural atmosphere that enables the Koreans in their 20s to easily wear Hanbok by popularizing Hanbok.

We collected age determination cases which were done at Yonsei university dental hospital, department of oral medicine from 1976 to 1999 to analyze it's tendency among Koreans. We analyzed 435 clients cases which were stored by age estimation program from January 1993 to December 1999. The results are as follows: 1. There were no significant difference in the sexual distribution (male : 52.0%, female : 48.0%) and more than half percent (51%) were 20's and 30's. 2. Among the age determination clients, those who wanted to decrease their age (50.3%) and those who wanted to increase their age (49.7%) shows similar in number. And the former case were predominant in the female clients, but the latter case in the male clients. Also the clients below six years of age were predominant in the former case, but the clients more than sixty were predominant in the latter case. 3. The purposes of age correction showed different distribution for ages: job or employment for 20's and 30's, marriage for 20's, registration for school for below six, welfare and other social services for 50 and older. 4. Age was estimated by Nolla's growth stage for 12 and under, calcification of the second and third molar for 12~20, and for 20 and over, Takei's tooth abrasion model was used. 5. The alleged age was in accordance with the documents and other information given by clients, but in the 20.6% of the estimation cases, the alleged age was discarded. In the results of the analysis of age determination cases in Koreans, many of the cases resulted from our historical turbulence and social distinctiveness, causing an increase in the necessity for age correction in each age group. For more accurate determination for each age group, further studies with Koreans must be done continuously.

Twenty Ardi lactating goats were used to investigate the effect of substituting 10%, 15%, and 20% of concentrate feed with date pits on milk production, composition, and blood parameters. Four isocaloric and isonitrogenous dietary treatments were used. Four levels (0% [control], 10%, 15%, and 20%) of date pits were used to replace concentrate feed. The forages to concentrate ratio used was 60 to 40. Dry matter intake (DMI) of goats fed diets containing 10% and 15% date pits was significantly (p<0.05) higher than those fed diets containing 0% and 20%. However, goats fed a diet containing 20% date pits were significantly (p<0.05) lower in DMI compared to those fed control diet. The protein percent was significantly higher for goats fed control diet compared to the other dietary treatments. Total solids percent was significantly the lowest for goats fed diet supplemented with 10% date pits. Goats fed a diet containing 20% date pits was significantly (p<0.05) higher in the total protein compared to those fed a diet containing 10%. In addition, goats fed a diet containing 15% date pits exhibited no significant differences in the total protein percent compared to those fed a diet containing 20% date pits. Triglyceride was significantly higher for goats fed diets containing 10% and 20% date pits compared to those fed 15% date pits. Results obtained in the present study suggest that date pits can be added up to 20% of the concentrate feeds into lactating Ardi goat diets without negative effects on their productive performance.

This study aimed to identify changes in upper body measurements and body shape types among women over a 10-year period based on data from the 6th and 8th Size Korea Anthropometric Surveys. The study used regression analysis to explore the relationship between various dimensions, enabling the prediction of different upper body dimensions based on height and waist circumference. The sample consisted of 1,179 women in their 20s who participated in the 6th (2010) and 8th (2020) Size Korea Anthropometric Surveys, with 33 items analyzed. Initially, most items, except those related to height, exhibited larger values in the 8th Survey than in the 6th, suggesting a general increase in the upper body dimensions of females in their 20s over the 10-year period. Subsequent factor analysis revealed three factors crucial for determining the upper body shape of women in this age group. The body shapes were then categorized into four distinct clusters. Regression analysis indicated that both waist circumference and height significantly influence most of the measured items, with waist circumference having a more substantial impact in most models. Through this research, we aim to provide foundational data that reflects the evolving upper body shapes of women in their 20s to enhance clothing production and improve the sizing system.

In narrow maxillary arch, midpalatal suture can be readily opened in growing children with maxillary palatal expansion. In adult patients, narrow maxilla is generally treated surgically because their growth are deemed completed due to their age. However, in patients under 25, midpalatal suture may not be closed. In addition, maxillary expansion may depend upon the closure of other maxillary sutures, which generally remain open at this stage. The present study attempted suture openings with palatal expansion on 5 female patients in their early 20's. The opening was successful in 4 patients, while only one patient showed no suture opening. In all 4 subjects, no discomfort or pain was present during s\expansion, and the successful suture opening was confirmed on occlusal x-rays. Therefore, for those patients with narrow maxilla in their early 20's, rapid palatal expansion or slow palatal expansion may offer a simple and less complicated option which, if successful, may preclude the need for surgery and thereby circumvent the psychological and financial burdens for the patients.

The purpose of this study is to suggest fundamental information about wearing method and production of brassiere, which is suitable for physiological hygiene and efficient action for elderly women. The subject is 418 elderly women aged 50∼69 years old. Data is processed by a computer(SAS) and is analyzed by using frequency, percentage, x²-test. The main results of this study are as follows. 1. Elderly women'weight and breast size are higher thant their younger counterparts'in their 20's, but the older and poorer women with more children have smaller weight and breast. Most of the elderly women feel that their breasts are drooped or falling apart. I fact, those elderly women who gave birth to more children have more drooped and wider breasts. The major type of elderly women'breast is the 'drooped breast' featured more by those elderly women who have more children. 2. Most of the elderly women began to wear the brassiere for the first time in their 20's the older women with more children began to wear the brassiere earlier, while those less educated and poorer began to protect their breasts with brassiere later. Many elderly women wear the brassiere to be protected from dirt, noise or look more neat, but day tend to wear the brassiere not all day around but at certain times, older, less educated and proper women with more children tend to use the brassiere for etiquette and less often. This group of elderly women feel tedious, stage or uncomfortable for the brassiere. 3. Most of the elderly women know about their brassiere size. Such variables as age, education and income are correlated positively with the interest in and consciousness of the brassiere size. All in all, the statistical distribution of elderly women's brassiere size is very wide, while most of them use 90A, 85A and 95A sizes. On the other hand, the most popular size of the under bust circumference is 85∼90cm, while their primary cup size is A.
