This study analyzed the attitude and effect of middle-age women on wearing girdles. Through this examination, we investigated types of girdles worn by middle-age women and compared and analyzed characteristics among types. By identifying middle-age women's need to wear girdles, this study enables effective development of girdles for middle-age women. Middle-age women's types of wearing girdles were analyzed according to three types of women wearing girdles: hate type, wearing preference type and inconvenience acceptance type. The hate type woman is frustrated with wearing a girdle because it impedes blood circulation, digestion, and causes fatigue. The wearing preference type woman wears a girdle to feel psychological satisfaction and self-confidence and thinks that wearing a girdle pushes the abdomen and supports the hip (hip-up effect). Women strongly agreed that body shape is made beautiful and the silhouette of the lower body is made beautiful by wearing a girdle. The inconvenience acceptance type of woman thinks it is inconvenient to wear a girdle, but nevertheless is satisfied with wearing a girdle. Based on findings of this study, development of girdles considering body shapes of middle-age women, development of soft materials and improvements facilitating dressing methods are needed.
Objective: This study aimed to evaluate the mean age of menarche, its secular trend in Korean women, and the relationship between malocclusion and the rate of skeletal maturation, as defined by menarcheal age. Methods: We retrospectively collected data on menarcheal age from 931 Korean women born during 1961 - 1997. Subjects were divided by the malocclusion type and birth-year decade into 3 and 4 groups, respectively. The mean menarcheal age for each group was determined, and one-way ANOVA was performed for intergroup comparison (p = 0.05). Two-way ANOVA was also performed to compare all the 12 subgroups (p = 0.05). Results: The mean age of menarche was 12.82 years for Korean women born during 1961 - 1997. A distinct downward secular trend of menarcheal age was noticed (p < 0.05). For the birth-year decade 1961 - 1970, the Class III malocclusion group showed earlier onset of menarche than the other malocclusion groups (p < 0.05), but the other birth-year groups did not show any significant difference in the type of malocclusion (p > 0.05). Conclusions: A positive secular trend towards earlier menarche exists among Korean women. Malocclusion does not show any significant relationship with the rate of skeletal maturation, as defined by menarcheal age.

Purpose : The purpose of this study was to investigate the development of korean vowels by acoustically analyzing whether children produce Korean vowels differently according to their age and gender between ages 4 and 6. Methods : A total of 104 children aged 4~6 years (56 males and 48 females) participated in this study. The participants were classified as either 4, 5, or 6 years old. Vowel speech data was obtained by asking the subjects to pronounce meaningful words in which the vowel in question was located in the first syllable. Speech analysis was performed using the Multi-speech 3700 program. Results : Age, gender, and vowel being pronounced all had significant effects on intensity. There was significant decrease with increasing age, and the intensity was significantly higher in male children than female children. Neither age, gender, nor the vowel being produced affected the fundamental frequency. The fundamental frequency produced did not differ by age or gender. The first and second formants had considerable effect on age and vowels, significantly decreased with age, and did not have a gender difference. Conclusion : The results of this study showed that children aged 4~6 have similar anatomical structures, but that maturity of speech motor skills required to pronounce vowels was correlated with age. The results of this study can be used to evaluate children's speech and develop speech therapy programs.

Automatic age estimation has been used in many social network applications, practical commercial applications, and human-computer interaction visual-surveillance biometrics. However, it has rarely been explored. In this paper, we propose an automatic age estimation system, which includes face detection and convolutional deep learning based on an inception module. The latter is a 22-layer-deep network that serves as the particular category of the inception design. To evaluate the proposed approach, we use 4,000 images of eight different age groups from the Adience age dataset. k-fold cross-validation (k = 5) is applied. A comparison of the performance of the proposed work and recent related methods is presented. The results show that the proposed method significantly outperforms existing methods in terms of the exact accuracy and off-by-one accuracy. The off-by-one accuracy is when the result is off by one adjacent age label to the above or below. For the exact accuracy, the age label of "60+" is classified with the highest accuracy of 76%.
This study was performed to establish the Cephalometric standards and growths change of Korean Teen aged group by McNamara's Analysis. The data from Cephalometric films of 161 male and 205 female subject aged from 10 to 18 years of Normal Korean were used for this study. The following results were obtained: 1. Means, standard deviation from measured values in each age group and sexual values were obtained. 2. Greater measurement stowed in male than female in Condylion to point A, Condylion to Gnathion, MaxilloMandible differential and ANS to mouton in linear measurement of 18 age group. 3. Condylion to point A, Condylion to gnathion, MaxilloMandible differential and ANS to Menton are increased as the age increased. 4. Facial axis angle and Mandible plane angle of 15 and 18 aged group showed less value than that of 10,11,12 age group. 5. There was no significant value changes of Lower incisor to A-Po, SNA angle and Lower pharynx by the increasing of age.
The purpose of this study was (1) to investigate the difference of temperament, self-regulation, and problem behavior according to children's gender and age, (2) to investigate the relationship among three variables by use of canonical correlation analysis. The subjects were 210 children ages from 3 to 5 in five day-care center in Incheon city. The SPSS WIN 12.0 Program was used to analyze the collected data. The statistical methods were Frequency, Percentage, Cronbach's ${\alpha}$, Two-way ANOVA, Correlation analysis, and Canonical Correlation analysis. The major results of this research are summarized as follows: (1) Children's temperament were significantly different by their gender and age. The boys got higher score than girls in adaptability, activity, and total temperament. Girls got higher score than boys in reactivity. The age 3 got higher score than the age 5 in activity and the ages 3, 4 got higher than the age 5 in total temperament. (2) Children's self-regulation were significantly different by their age. The children who were older got higher scores in self-regulation ability. (3) Children's problems behavior were significantly different by their gender and age. The boys got higher score than girls in anxiety behavior, aggressive behavior, hyperactive/distractive behavior, and total problem behavior. And the ages 3, 4 got higher score than the age 5 in anxiety behavior and hyperactive/distractive behavior. The age 4 got higher score the ages 3, 5 in aggressive behavior and the age 3 got higher score the ages 4, 5 in total problem behavior. (4) Canonical correlation results showed that stable temperament and self-regulation were positively correlated and self-regulation and problem behavior were negatively correlated.
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.
The differentiation and development of preadipocyte into mature adipocyte are regulated by transcription factors, such as CCAAT enhancer binding protein (Cebp) gene family and sterol regulatory element binding transcription factor 1 (Srebp1). Steroid hormones give influences on the development and function of adipocyte. The present research examined expression patterns of CCAAT enhancer binding protein alpha (Cebpa), CCAAT enhancer binding protein beta (Cebpb), CCAAT enhancer binding protein gamma (Cebpg), sterol regulatory element binding transcription factor 1 (Srebp1), androgen receptor (Ar), and estrogen receptors (Esr) among different epididymal fat parts during postnatal period by quantitative real-time polymerase chain reaction. In the distal epididymal fat, expression of Cebpa, Cebpb, Cebpg, Srebp1, Ar, and Esr2 was increased until 12 months of age, while expression of Esr1 was decreased at 5 months of age and was not detectable after 8 months of age. In the proximal epididymal fat, transcript levels of Cebps and Srebp1 were increased at 8 months of age, followed by decreases of Cebpb and Cebpg transcript levels at 12 months of age. An additional increase of Srebp1 expression was observed at 12 months of age. Expression of Ar and Esr2 were increased until 8 months of age, followed by a drop of Ar expression level at 12 months of age. Expression pattern of Esr1 was similar to that in the distal epididymal fat. In the tail epididymal fat, expression of Cebpa, Cebpg, Srebp1, Ar, and Esr2 was increased with age. Esr1 was not detectable at all. The highest level of Cebpb was observed at 8 months of age. These data suggest the possibility of developmental and functional differentiation among the epididymal fat parts.

The purpose of this study is to identify the types of consumer problems involving the use of online game services in Korea. This study analyzed the consumer damage cases by age and type that were reported to the Korea Consumer Protection Board (KCPB). The results of this study are as follows: The online game complaints varied by age. In the case of children, most complaints involved phone charging online game fees without parents' consent. There were similarities in the victimization of teens and children according to reason for complaint, handling result and type of damage. However, based on method of charging, mobile phone and credit card payments were causes in the case of teen victimization. Meanwhile, complaints among adults showed more complexity than the previous two groups such as cases relating to online game companies illegally seizing game items and game accounts, and charging fees for unused services caused by identity theft. By type of charging method, most complaints involved phone and mobile phone payments. According to the analysis result of online game victims, the monetary damage of consumers did not differ among socio-demographic variables such as age, residence, gender and occupation but there was difference in the method of charging. In the handling period, differences could be seen by age, year, gender and type of damage.

This study presents characteristics of representative five hand dimensions including hand length, medius finger length, hand circumference, hand breadth and hand thickness, and hand scales by gender and age for Koreans. The study was based on data of hand dimensions published in 2008 by Korean Agency for Technology and Standards. The hand dimensions of males were nearly the same as those of females until age of 12~13(10~11 in hand thickness), but the males' were larger than the females' from age group of 14~15 or 12~13. The growth of the hand dimensions was found until age of 12~13(14~15 in hand thickness) in females and 16~17 in males. After the age groups, the hand dimensions was almost the same irrespective of age groups. ANOVA was performed to investigate significant factors affecting hand dimensions. Representative five hand dimensions were significantly affected by gender and age, while they were not affected by occupation. Two hand scales were proposed depending upon gender, for easily using hand characteristics in design stage of hand relevant products. In addition, regression equations were provided for quantitatively predicting hand dimensions on the basis of representative five hand dimensions.
