Purpose: This study examined the possibility of muscle strength and balance ability improvement through coordinative locomotor training by making a difference on the supporting plane using a resistance band for adolescent athlete of Taekwondo sparring athletes. Methods: A total of 22 students were selected as to the participants of the study, and 11 students each were randomly assigned to the control and experimental group for coordination locomotor training using a resistance band on stable and unstable supporting surface. The training period was 60 min, three times a week, for 8 weeks in total. To confirm changes on balance ability of each participant, balance assessment devices are used. Moreover, surface electromyography was used for muscle strength evaluation. Results: After coordinated locomotor training using a resistance band for 8 weeks, the difference bet ween groups was not significant; Also, the improvement in strength was no significant difference in other muscles in the between groups, but there was a significant in the muscle activity of the rectus muscle of the right thigh in the experimental group. Conclusion: The participants demonstrated that coordinative locomotor training using the elastic band on an unstable supporting surface was able to obtain junctional effects for the prevention of exercise injuries in youth taekwondo sparring athletes, and muscle activity exercise of the rectus muscle of the right thigh was particularly effective.

Purpose: This study aimed to identify the reciprocal relationship between parenting attitudes (positive and negative) and adolescent emotional problems as indicated by aggression, social withdrawal, and depression. Methods: This study analyzed longitudinal data from 2,325 parents and their children from the Korea Children and Youth Panel Survey 2018 at three time points over a three-year period (the first to third grade of middle school). Autoregressive cross-lagged modeling was conducted using AMOS 26.0. Results: The results indicated that both parenting attitudes and adolescents' emotional problems were relatively stable over time. In other words, the parenting attitude at a previous point affects the parenting attitude at a later point, and the emotional problem at the previous point continues to affect the emotional problem at the later point. There were no significant cross-lagged effects from both positive and negative parenting attitudes to adolescents' emotional problems. In contrast, adolescents' emotional problems at previous time points positively predicted negative parenting attitudes at later time points. In other words, if there were many emotional problems of aggression, social withdrawal, and depression in adolescents at a previous time, negative parenting attitudes such as rejection, force, and inconsistency at a later time increased. Conclusion: This study can reflect the characteristics of the development of independence in adolescence. Parents should deal with their children's emotional problems based on their understanding of the developmental characteristics of adolescence, and this study provides a strategy for parents to establish appropriate parenting attitudes for adolescents with emotional problems.

Make-up culture has recently emerged as a major trend among adolescents, and their knowledge of this culture is acquired from their peers. Adolescence is a period in which peer relationships have a significant effect on individuals' behavior and self-esteem. Also, adolescents are conscious of others' evaluation because they only want to exhibit their ideal-self. They generally apply make-up for various reasons; pursuing ideal beauty, concealing their insecurities and improving their own self-esteem. The purpose of this study is to design and implement the MUSE(Make-Up & Self-Esteem) project, to reduce self-esteem disparity based on make-up status. Ten female adolescents(mean age=17.0 yrs, SD=1.49) participated in the MUSE project, in which the participants gradually reduced their make-up steps and posted feelings about this on SNS. Also, events were designed for the participants to enhance their interest and become more focused on themselves without make-up. Resultantly, it was obeserved that after the project, the gap between the particiapnts' self-esteem with and without make-up decreased. More specifically, there was no significant difference in self-esteem with make-up before and after participating in the project, but a significant increase was observed in self-esteem without make-up after the project. Although the participants were mostly satisfied with the project, individual interviews were conducted to obtain feedback regarding how the project could be improved. The participants suggested that future project could be developed within their own peer group and the term of the project could be extended so that the participants could become accustomed to daily make-up reducing steps.

Using Random Sampling, the authors measured the body heights and weights of 31,151 persons - 17,102 in males and 14,049 in females from metropolitan, urban and rural areas between 6 to over 80 year old - for the purpose of investigating the type and the actual condition of the Korean's growth and development. At first, on the basis of the results, the authors measured the growth and development, various kinds of physiques, nutritional index of the 6 to 20s age group. Second, the authors presented the standard body weight of males and females by their body height, who were in the end of their growth (20-29 age group). Third, the authors calculated and presented the normal adapted body weight of the age group who were over 30 age after the growth had been completed. Forth, the author presented the obesity rate of the adults over 20 years old by body mass index. Finally, the authors compared chronological change of the Koreans' body heights and body weights with the results of other researchers. 1. Body Measurement Rapid growth, in terms of body height, which is described by a straight line on a growth curve has been observed among males in the ages 6-13 and among females 6-14. That growth curve turned out to be slower among the people of higher ages by both sexes. The cross-over occurred in both sexes at 11-14. The highest growth rate for a year is at 13-16 for males and 11-13 for females. This indicates that females enter a rapidly growing stage 2 years earlier than males. 2. Various Physiques and Nutritional Index Rapid growth, in terms of Relative Body Weight Index, which is described by a straight line, has been observed among males in the ages 6-16 and females in the ages 6-14. The cross-over occurred in both sexes 12.5-14.5 age in the adolescencent period. Whereupon females outgrow males. The Roher Index displayed more good value in case of females than male and in the adolescent period, the level of fullness is lower than after the completion of development. The Kaup Indices of both sexes increase with age. The index is less than 2.0 for males in 6-14 age group and for females in 6-13 age group and with this, it appeared that development of horizontal axis to long axis is poor. The index is more than 2.0 after 15 age group in males and 14 age group in females and developmental state4 age group and for females in 6-13 age group and with this, it appeared that development of horizontal axis to long axis is poor. The index is more than 2.0 after 15 age group in males and 14 age group in females and developmental state Body Mass Index is less than 20 for males 6-14 age group and for females in 6-13 age group. In the case of the higher age group, that index maintains a normal state.

Purpose: The present study intended to reveal the association between the physique of adolescent women and dysmenorrhea, and the factors related to the frequency of dysmenorrhea. Methods: The study subjects included 511 girls of a women's high school in Daejeon city and they were, during the period of March 1st through April 30th, 2005, given self-administered questionnaires about frequency of menstruation, age, physique, exercise, and such menstruation-related items as age of menarche, menstrual period and days, and amount. Results: As with the frequency of dysmenorrhea, 38.4% experienced it 「always」, 44.6% 「occasionally」, and 17.0% 「almost scarcely」, and those with dysmenorrhea accounted for 83.0% of the subjects. The frequency of dysmenorrhea was not significant difference according to the BMI and HPI. However, the lower the age of menarche and the greater the amount of menstrual flow, the more frequent dysmenorrhea. The symptoms of dysmenorrhea included the highest frequency of low back pain(68.5%) and it was followed by abdominal pain(65.9%), sensibility(54.0%), fatigue(51.7%), and nervousness(49.5%). These accompanied symptoms tended to be worse as the frequency of dysmenorrhea increased. The multiple logistic regression analysis revealed that the relative risk of frequency of dysmenorrhea is 2.2 times in age of 14, by a standard age of 15 as menarchial age, 2.2 in 13, and 3.1 in below 12. The menstrual days was 3.0 times in both below 2 days and over 8 days with the standard days of 3-7 days. The menstrual amount was 1.9 times in the group with a greater amount of menstrual bleeding and 1.5 times in the group with a less amount than the normal group, respectively. Conclusion: The above results suggest that the rate of experiencing dysmenorrhea was up to 83.0% and 38.4% from these had dysmenorrhea upon every menstruation. It is thought that dysmenorrhea could be a great disadvantage sufficient to impair optimal health to a larger body of school girls. Further, for quality of life, it is required that more fundamental strategies instead of pain killers or others for palliation of dysmenorrhea would be established among adolescents.

Adolescence is a transitional stage of physical development which occurs during the period from puberty to adulthood. Going through this period, various parts of an adolescent's body grow at different rates, leading to different body shapes and proportions when compared to adults. Therefore, this study aimed to investigate the body sizes and shapes of junior high school boys from ages 13-15 based on body measurement items that are used as the basis for school uniform designs including jackets, shirts, and pants. For this, the study sought the basic data needed to develop body shapes and school uniform patterns for junior high school boys using the data from the 6th Size Korea Survey (2010). Specifically, it provided basic data for the development of school uniform patterns that fit well through the classification of bodies into particular types. After extracting body shape componen a cluster analysis using ANOVA was performed. According to the factor analysis conducted to determine body shape components, 5 factors were obtained as follows: Factor 1: bulk and horizontal size, Factor 2: body height and length, Factor 3: shoulder shape and length, Factor 4: characteristics of horizontal size, Factor 5: shape of the upper body with a variance of 82.62%. To classify junior high school boys' body shape was determined using various characteristics, and a cluster analysis was performed with the variables obtained by the factor analysis. For this, body shapes were classified into 3 different types: Type 1 accounted for 33.4%, with a total of 463 subjects. This type was a tall, long body individual with the smallest bulk and size. Type 2 accounted for 22.7%, with a total of 315 subjects. This type was large in bulk and horizontal size, but the lowest in height and length. Type 3 accounted for 43.9%, with a total of 610 subjects. This type was close to average in terms of horizontal size, length, and height. To develop well-fitting school uniforms for junior high school students, there should be further studies on changes in body shape and their associated causes. The study results will be available as basic data for comparing branded school uniform patterns for junior high school boys and developing school uniform patterns based on body shape, using 3D virtual clothing simulations.
