This study tried to compare and analyze the body measurements of female adults in China by various age groups. As for the study method, direct and anthropometric measurements were used on the 357 female subjects living in Yenbien and Harbin, China, consisting of 122 women in their 20's, 114 women in their 40's, and 121 women in their 60's. The results were as follows: 1. The comparison of major body measurements between Korean Chinese and Korean in land indicated that the former were shorter and plumper than the latter. Those groups in their 60's did not show any significant difference in height related measurements and revealed less differences in body measurements comparing to other age groups. 2 The comparison of Chinese anthropometric measurements among age groups of Korean Chinese indicated that, higher the age, shorter the height measurements, the leg length shorter, the upper-half body length longer, and the chest drooping due to the breast descent. 3. The comparison of indirect measurements among age groups of Koreans Chinese indicated that those in their 60's showed many items of big discrepancies in comparison with those in their 20's or 40's, with wide gap in discrepancies, thus resulting in large differences among individuals.

As interest in skin care increases, this study aims to contribute to the development of the beauty self-care market by providing basic data through the measurement of the oil and moisture skin condition of women in their 20s and 30s. The study was conducted from November 27, 2020 to January 31, 2021, with 20 women in their 20s and 30s divided into 4 groups, A~D, by age, 5 per group. Skin measurements were taken four times at 4 hour intervals at 0H, 4H, 8H, and 12H based on the first measurement that was taken within 30 minutes after waking up, and the oil and moisture indices were observed over time. As a result, both T and U zones showed significant differences in moisture levels over time, with no difference between groups for both T and U zones. Moisture decreased the most between 0H to 4H, and moisture changed the least between 4H to 8H. Changes in moisture increased the similar at 0H and 12H. The oil condition changed more irregularly compared to moisture over time, but all groups showed lower oil content in the U-zone compared to the T-zone. Overall, the facial oil and moisture conditions of women in their 20s and 30s changed over time, indicating that the skin changes in real time. The fact that the skin data, which was measured in the primary activity living environment, can be used as basic research data in the beauty self-care market is meaningful.

This is a follow-up study to "An Analysis of the Fitting of Plus-sized Women's Formal Jackets in On-line Shopping Malls", in which we compiled basic sizes of formal jackets sold in online retailers for plus-sized women and compared specific measurements of the jackets from each retailer. Emphasizing a comparison of age groups 20-39 and 40-59, fit evaluations and analyses were conducted in order to provide data to help manufacturers develop formal jacket patterns that reflect physical characteristics of plus-sized consumers and offer better physical fit. The surveys and evaluations were conducted between October 2007 and May 2008. and the compiled data were analyzed using the SPSS 17.0 statistics program. The results were summarized as follows. The two age groups gave different evaluations of the fit problems in the women's formal jackets sold in online retailers. Whereas the age group 20-39 felt that the main problems were in the shoulder, armscye, upper arm, waist, abdomen and hip areas, the age group 40-59 said that they found more problems in the armscye, upper arms, sleeve length and jacket length. Modifying the shoulder area, armscye depth and jacket length severely compromises the jacket's balance, and attention to these areas must be given during pattern design.

Silver nanoparticles (AgNPs) are widely used nanoparticles and they are mainly used in antibacterial and personal care products. In this study, we evaluated the effect of AgNPs on cell death induction in the murine dendritic cell line DC2.4. DC2.4 cells exposed to AgNPs showed a marked decrease in cell viability and an induction of lactate dehydrogenase (LDH) leakage in a time- and dose-dependent manner. In addition, AgNPs promoted reactive oxygen species (ROS)-dependent apoptosis and AgNP-induced ROS triggered a decrease in mitochondrial membrane potential. The activation of the intracellular signal transduction pathway was also observed in cells cultured with AgNPs. Taken together, our data demonstrate that AgNPs are able to induce a cytotoxic effect in DCs through ROS generation. This study provides important information about the safety of AgNPs that may help in guiding the development of nanotechnology applications.

The purpose of this study is to identify cross-cultural features among Korea, China, and Japan by comparing differences in facial awareness, attractiveness preferences, and consideration of facial parts in a group of Korean, Chinese, and Japanese men and women as they evaluated the faces of Korean women in their 20s. A survey was conducted targeting male and female Korean, Chinese, and Japanese college students in their 20s. Frequency analysis, ANOVA, Duncan test, factorial analysis, and reliability analysis, MANOVA were carried out using SPSS 18.0. The results of this study are as follows: Faces of Korean women in their 20s were evaluated by Korean, Chinese, and Japanese men and women in their 20s and were classified into four categories as 'Youthfulness', 'Classiness', 'Friendliness' and 'Activeness'. Differences in facial image awareness were observed depending on nationality and gender. Korean participants were found to place importance on overall morphological factors; The Japanese focused on the eyes; and the Chinese on the skin color. Women of all nationalities showed, on average, a higher awareness of facial parts than men. No significant differences in facial attractiveness preferences were found based on nationality or gender, but there were differences in how the participants evaluated faces for attractiveness, showing that reasons for preferences may vary even if the preferences are the same.

An analysis of adult women's somatotypes classified by drop values can provide important preliminary data in determining standard clothing sizes for mass production of ready-made clothes. This is because the values are based on measurements of girth, which is essential information in the size-setting process. Adult women's body types are classified according to drop values in a standard clothing size system adopted by Korea and several other countries. This study aims to identify somatotype characteristics of adult women aged 20 to 69 by using five types of drop values: bust-waist, hip-waist, hip-bust, abdomen-waist, and hip-abdomen. Statistical cluster analysis of collected data revealed four somatotypes among adult women. Type R, with a developed lower body, accounted for 36.6%, and its bodyline was found to be closest to the average adult woman. Type X, constituting 25.4%, had the curviest contours of all and relatively large hip measurements, with the thinnest figure. Flat abdomen and hips characterized type Y, which accounted for 18.9%. Lastly, 19.0% fell into type H, the most obese figure, in which abdomen girth exceeded hip measurements. Since type H has excess fat deposits in the abdomen, not only hip measurements but also abdomen girth should be considered when designing top longer than torso-length and bottoms.

The purpose of this study is to analyze breast shape by age, to classify breast types and then to suggest brassiere size chart. The subject of anthropometric measurement were 232 women in 20's and 40's. The direct anthropmetric measurement were analyzed by mean, standard deviation, duncan test, T-test, ANOVA, factor & cluster analysis The results are as follows; 1) as a result of analysis for the measurements, according to the increase of age, the items of height were decreased and the items of width, depth, cir- cumference, length were increased, being obesity and breast points were dropped. So the volume and bottom area of 40's women's breast were lager than 20's women's. The width of breast points was bide by increasing of intereior. 2) as a result of factor analyxis, 5 factors were extracted as important factor of breast shapes(obesity of breast and location of breast point, breast height and volume, upper dimensions of breast/lower dimensions of breast, interior dimensions of breast/exterior dimensions of breast, volume of the lower part and drop of breast) 3) as a reslut of cluster analysis, the breast shape were classified into 4 types. namely, typel has the smallest volume, bottom area of breast and the slenderest breast, type2 was the second obesity type. type3 was middle sized type. type4 has much dropped, wide bottom area of breast and the biggest form. 4) To establish brassiere sizing system, the loss funtion was used to decide interval of under bust girth and cup size of size chart. 20 brassiere sizes were established and the size chart covers 92.2% of all subject.

The purpose of this research is to analyze the plasticity of women's hats in the 20th century. This paper reveals the characteristics of formation through the historical survey of women's hats, which can be used as a basic design data for developing high value added products. Hats have been worn to play as key roles of various social codes. During the 20th century, functional roles of hats still existed, and the roles of ornaments had been gradually increased, however, the roles with symbolic meanings of regarding social class had been weakened. The major plasticities of hats can be generally analyzed based on the shape, material, technique, and ornament. As the time passed by to the end of the 20th century, flat-shape hats have been worn casually in both Western countries and Korea.

The purpose of this study was to investigate the test-retest of plantar pressures using the F-Scan system over speeds and plantar regions. 6 healthy female subjects in 20's were recruited for the study. Plantar pressure measurements during locomotor activities can provide information concerning foot function, particularly if the timing and magnitude of the loading profile can be related to the location of specific foot structures such as the metatarsal heads. The Tekscan F-Scan system consists of a flexible, 0.18mm thick sole-shape having 1260 pressure sensors, the sensor insole was trimmed to fit the subjects' right. left shoes - sneakers shoes & dress shoes. It was calibrated by the known weight of the test subject standing on one foot. The Tekscan measurements show the insole pressure distribution as a function of the time. This finding has important implications for the development of plantar pressure test protocols where the function of the forefoot is important. According to the result of analysis it is as follows 1) Center of force trajectory in women's dress shoes display direct movement, compare with center of force trajectory in Sneaker shoes displays a little bit curved slow pronation movement. Sneaker shoes in forefoot part display very quick supination movement, therefore, this shoes effects negative effectiveness for ankle's stability Considering center of force trajectory analyzing the more center of force close straight line, the more movement can be quick movement for locomotion. For foot pressure distribution, center of force trajectory in locomotion is better to curved trajectory with pronation movement. So sneaker shoes style is good shoes considering center of pressure distribution trajectory compare with women's dress shoes. 2) Women's dress shoes increased peak pressure in medial, this is effected by high hill's height. The more increased women's dress shoes's height, the more women's peak pressure will increase, pronation can increase compare with before. Supination movement increase, this focused pressure in lateral, also, supination increased more. If the supination movement increased, foot pressure focused in lateral, therefore, it is appeared force distribution in gait direction. This is bad movement in foot's stability. 3) Women's dress shoes in landing phase displayed a long time, this is when women's dress shoes wear, gait movement is unbalance, so, landing phase displayed a long time. For compensation in gait, swing phase quick movement. 4) Women's dress shoes displayed peak pressure distribution in lateral of rearfoot part, Sneakers shoes displayed peak pressure distribution in medial of forefoot part. Its results has good impact absorption compare with women's dress shoes. In forefoot part, sneakers shoes has good propulsive force compare with women's dress shoes.

Objectives: The purpose of this study is to analyze the perception that women in 20s and 30s have on Traditional Korean Medical(TKM) treatment on the leukorrhea. Methods: We studied the perception of TKM treatment by questionnaire From October 1 to November 20, 2010. A questionnaire was given to 50 women and we studied 47 except 3 questionnaire which have inappropriate answer. Results: 1. In 47 women, 46(97.9%) women have heard about leukorrhea, 1(2.1%) woman hasn't heard about it. 2. In 32 women who suffered from the leukorrhea, 14(43.8%) women checked up for leukorrhea. 18(56.2%) women doesn't checked. 10 of 14 women took the medical treatment (drug or injection) and 2 of 14 women took the TKM treatment. 3. In 32 women, 16(50.0%) women know about TKM treatment for leukorrhea, 16(50.0%) women don't know. 4. In 32 women, 20(62.5%) women have intention of TKM treatment for leukorrhea, 2(6.2%) women don't have, and 10(31.3%) women don't know. The biggest obstacle was the high cost of TKM treatment. Conclusions: Many women are willing to take TKM treatment on the leukorrhea. We need more accumulation of data for demonstrating the efficacy and safety of TKM treatment.
