Purpose: The purpose of this study was to examine the sexual maturation, body image, and self-esteem of Korean elementary school girls with symptoms of precocious puberty compared to those with no symptoms of precocious puberty. Methods: The subjects were 309 girls of lower grades in elementary school. Tanner's Sexual Maturation Rating (SMR), Self Image Scale, and Self-esteem Scale were utilized to determine the presence of symptoms of precocious puberty, body image, and self esteem. Collected data were analyzed by Chi-square test, independent t-test, and one-way ANOVA using the SPSS/WIN 17.0 program. Results: The percentage of the girls with breast development was 14.9%. Breast development usually began in the third grade (56.5%). Of the subjects, 0.3% were experiencing menstruation. Breast development was related to grade, age, height, weight, and a cause of worry. There was a significant difference of body image between girls with breast development in the first grade and in the second grade. Conclusion: An effective intervention that can improve the self-image of children with symptoms of precocious puberty should be developed to prevent and treat physical and mental problems related to sexual maturation.

This study investigated the relationship between school-age children's overt/covert narcissism with self-control and mothers' parenting. The subjects were 517 children in the 5th and 6th grades attending elementary schools located in Daegu and Gyeongbuk Province. The collected data were analyzed by t-test, Pearson's correlation, multiple regressions and SPSS Win 19.0 was used. The results were as follows: (1) School-age children's overt narcissism differed in boys and girls. However, this was not the case for covert narcissism. (2) The overt narcissism of school-age boys and girls was positively correlated with self-control. However covert narcissism was negatively correlated with self-control. (3) The active-responsive and active-restrictive parenting of mothers influenced on the overt narcissism of school-age boys, while the active-responsive parenting of mothers influenced the overt narcissism of school-age girls. Also, the active-responsive and active-restrictive parenting of mothers influenced the covert narcissism of school-age boys, while the active-responsive and passive-permissive parenting of mothers influenced the overt narcissism of school-age girls. (4) The active-restrictive parenting of mothers was the most powerful factor in the overt/covert narcissism of school-age boys and the covert narcissism of school-age girls.

Maximal active movements of the mandible in the vertical and the horizontal plane were measured in 147 boys and 155 girls. with an age of 13, 15, 17 years respectively. The studied persons had no pain or severe symptoms of dysfunction of the masticatory system and the method used in this paper was devised by Agerberg, and the numerical calculations were performed at the Dept. of Medical Engineering of Seoul National University Hospital. The obtained results were as follows : 1. The mean values of maximal opening in 13 year-old boys and girls were 58.5 mm,58.9 mm respectively, and the mean values of boys were increased with age. 2. The mean values of maximal lateral movement to the right in 13-year-old boys and girls were 9.1 mm, 8.3 mm respectively, and the mean values to the left were 9.3 mm, 8.7 mm resprctively. The mean values were not increased with age in both. 3. The mean values of maximal protrusion in 13-year-old boys and girls were 8.7 mm, 8.1 mm respectivly, and in all ages the mean values of boys were larger than those of girls. 4. The range of maximal mandibular movements in teen-agers with 95% probability prediction ellipses were presented.

Recently in the apparel industry, early adolescent girls are emerging as a new consumer group. In response to this, companies are developing clothes, cosmetics, underwear, etc. This study proposed a new size range and size interval for early adolescent girls and presented reference measurements for body parts necessary in designing clothes. For this purpose, a total of 529 girls aged between 10 and 14 were measured and data were collected from 42 anthropometric measurements and 41 photographic measurements per a person. SAS 8.1 was used in data analysis including means, standard deviations, frequency analysis. Based on the results, this study proposed: for Type A - 7 sizes (140A-67, 145A-65, 145A-69, 150A-69, 150A-73, 155A-73, 155A-76): for Type X - 7 sizes (150x-72, 155x-72, 155x-77, 160x-77, 160x-80, 165x-77, 165x-80); and for Type H - 8 sizes (145H-74, 145H-82, 150H-78, 150H-82, 155H-82, 155H-86, 160H-86, 160H-88). Reference measurements suggested for upper garments were 9 items. The outcome of this study may be used as a basic material for adolescent apparel manufacturers to set their apparel sizing system and to supply their consumers, namely, adolescent girls with products fitting their somatotype.

This research attempts to analyze the physical characteristics of middle school girls and compare the product sizes and patterns of school uniform blouses by brand. And wearing tests were performed regarding the appearance of blouse by bland. The results are follows. The standard deviation for bust circumference and waist circumference of middle school girls measured in 2004 were showed extremely large difference among individuals compared to the previous results. While waist back length reached adult size by $2^{nd}$ grade high school, bishoulder length reached adult size by $2^{nd}$ grade middle school. And girls after $2^{nd}$ grade middle school had their depth and breadth of bust, underbust circumference and bust circumference growing proportionally. These results need to be reflected in producing a pattern drafting for middle schoolers. By comparing wearing test results on appearance, it was shown that in terms of ease of bust circumference, the expert group evaluated brand with less ease as not having adequate ease compared to brand, while the middle schooler group evaluated as having sufficient ease. The front silhouette also showed same results. This reflects the preference for appearance by the middle schooler group, which is a factor to be considered during pattern drafting of school uniform blouse.

This study analyzes the characteristics of somatotype changes of girls from the ages of 13 to 18 that provide basic data on clothing construction for middle and high school girls. We use data obtained from body measurements of 1,590 adolescent girls 13 to 18 years of age provided in the 6th national anthropometric survey report. The differences among the age groups for 56 direct measurements were analyzed by ANOVA, and the structures of the differences by SNK (Students-Newman-Keuls test) were analyzed. The two major growth ages were 'ages 13-14' and 'ages 15-16'. The first major growth ages focused on all measurement items of height, length, circumference, breadth, depth and other items. The second one focused on measurement items of height and length of torso, circumference, and breadth of lower body. The major growth pattern of the age groups was 'ages 13<14&15<16&17&18' which appeared focused on the height and length items of upper body and torso, the width items of lower body and the circumference items of upper body and lower body. The measurement items of front length like waist front length, N.P. to B.P to waistline, N.P. to B.P., and B.P. to B.P. showed the growth pattern for 'ages 13<14<15<16<17&18'.

The purpose of this study was to investigate the association of protective and risk factors with adolescent delinquency. Using nationally representative data from the National Longitudinal Study of Adolescent Health (Add Health) project, the delinquency level and the influence of individual characteristics, dyadic relationships in the family, school and peer variables on adolescent delinquency were examined by gender. Boys and girls differed in delinquency level with boys showing significantly higher delinquency than girls. The relative influence of protective and risk factors in individual, familial, peer, and school contexts differed by gender as well. More diverse variables influenced the delinquency level of girls than that of boys.

The author investigated the carpal bone and ephiphyses on the roentgenographic films. Several methods have been used in the study of carpal bones but I have calculated the numbers of ossification center. The subjects consisted of 259 boys and 239 girls from 3 to 13 years of age. The results are summerized as follows; 1. The number of ossification center were increased in aging both boys and girls. 2. Ossification tendency was more faster boys than girls and the difference of left and right hand were non significant. 3. The ossification of ephiphyses was completed in 4 years of age.
