Objective: To investigate the phenotypes and predominant skeletodental pattern in pre-adolescent patients with Pierre-Robin sequence (PRS). Methods: The samples consisted of 26 Korean pre-adolescent PRS patients (11 boys and 15 girls; mean age at the investigation, 9.20 years) treated at the Department of Orthodontics, Seoul National University Dental Hospital between 1998 and 2019. Dental phenotypes, oral manifestation, cephalometric variables, and associated anomalies were investigated and statistically analyzed. Results: Congenitally missing teeth (CMT) were found in 34.6% of the patients (n = 9/26, 20 teeth, 2.22 teeth per patient) with 55.5% (n = 5/9) exhibiting bilaterally symmetric missing pattern. The mandibular incisors were the most common CMT (n = 11/20). Predominant skeletodental patterns included Class II relationship (57.7%), posteriorly positioned maxilla (76.9%) and mandible (92.3%), hyper-divergent pattern (92.3%), high gonial angle (65.4%), small mandibular body length to anterior cranial base ratio (65.4%), linguoversion of the maxillary incisors (76.9%), and linguoversion of the mandibular incisors (80.8%). Incomplete cleft palate (CP) of hard palate with complete CP of soft palate (61.5%) was the most frequently observed, followed by complete CP of hard and soft palate (19.2%) and CP of soft palate (19.2%) (p < 0.05). However, CP severity did not show a significant correlation with any cephalometric variables except incisor mandibular plane angle (p < 0.05). Five craniofacial and 15 extra-craniofacial anomalies were observed (53.8% patients); this implicated the need of routine screening. Conclusions: The results might provide primary data for individualized diagnosis and treatment planning for pre-adolescent PRS patients despite a single institution-based data.

Objective: The purpose of this study was to examine pathways from parent attachment to adolescent life satisfaction and to determine the mediating roles of peer attachment and romantic relationships. Methods: The participants were 221 high-school students (117 boys and 104 girls) living in Jeonnam province who had been in a romantic relationship for more than 3 months. The data were analyzed by t -tests, Pearson correlations, and SEM using SPSS 19.0 and Amos 18.0. Results: Based on the research objective, 4 important results were summarized. First, father attachment and mother attachment had direct effects on adolescent life satisfaction. Second, mother attachment had an indirect effect on adolescent life satisfaction through peer attachment. Third, father attachment had an indirect effect on adolescent life satisfaction through romantic relationships. Fourth, mother attachment had an indirect effect on adolescent life satisfaction through peer attachment and romantic relationships. Conclusion: The results from this study highlight the significant roles of parent attachment, peer attachment, and romantic relationships in adolescent life satisfaction. Specifically, the roles of father attachment and of romantic relationships in adolescent life satisfaction, which have seldom been explored in previous studies, should be emphasized. The findings can be used as an important basis for prospective research and practices for improving adolescent life satisfaction.

Background: Adolescence is the transitional period between childhood and adulthood. We have to pay attention to their psycho-social problems as well as their physical symptoms. In this context, we need to investigate the adolescent depression tendency and its related factors. Method : From May to June in 1008, we chose one elementary school, one middle school and one high school in Seoul and surveyed for all students who were above the 4th grade of elementary school and their parents. We analyzed the data for 3,685 students. Result: From the 6th grade of elementary school to the 1st grade of high school, the girls' DSRS(Depression self-rating scale) score was significantly higher than the boys'. The DSRS score was increased from the 2nd grade of high school for boys and from the 1st grade of high school for girls. The Pearson correlation coefficient between age and DSRS score was 0.16(p<0.01) and that between APGAR and DSRS score was -0.45(p<0.01). The median number of psychosomatic symptoms of the past month was 6, and when students complained for more psychosomatic symptoms, the DSRS scores were higher. Those who drank or smoked ranked significantly higher in DSRS score; and, those who exercised regularly, had leisure activity, and had a faithful person for counselling ranked significantly lower in DSRS score. Conclusion : Adolescents who complained of many psychosomatic symptoms needed to be screened for depression. A primary physician have to intervene about health related behavior such as family function, smoking, exercise and relieving stress.

The objective of this study is to identify the secular trend in age at menarche and to investigate the factors influence the early menarche(<12 years old) among Korean middle and high school girls. We analyzed data from the Korean Youth Risk Behavior Web-based Survey(KYRBWS) 2006-2014. This study was a descriptive study of 216,917 Korean middle and high school girls born between 1988 and 2002. Linear trends test performed to assess the trend age at menarche and percentage of early menarche. Multiple logistic regression analysis was to assess the risk factors influence the early menarche. Mean age at menarche decreased from $12.61{\pm}1.32$ years for middle and high school girls born 1988 to $11.88{\pm}0.75$ years for those born 2002(p for trends<.001). Percentage of early menarche increased from 19.7% to 25.2% between 1988 and 2002(p for trends<.001). Living in city, higher stress level, short sleep duration, and higher body mass index were associated with an early menarche among middle and high school girls(all p<.001). We found that age at menarche is still falling in the Korean adolescents, and it need intervention strategies to control the early menarche.

The purpose of this research was to examine the effects of sensation seeking and socialization on the risk taking behavior of adolescents. The subjects were 460 3rd year high school adolescents (272 boys and 188 girls) in Seoul, Korea. Data were collected through questionnaires, including the Arnett Inventory of Sensation Seeking (1994) a socialization scale (mother's parenting style, parent's open communication and relationship with friends), and a risk taking scale devised by the researcher. The results showed that both the degree of sensation seeking and the socialization process influenced risk taking behaviors in both males and females. The effect of sensation seeking on risk taking behavior was mediated by the degree of communication with fathers for male but not for female adolescents. For males, sensation seeking directly and indirectly influenced risk taking behaviors through closeness with risk taking friends. For females, sensation seeking did not directly influence risk taking behavior but had an indirect influence through closeness with risk taking friends. Implications were discussed in terms of sensation seeking and socialization.

The relations between family functioning (cohesion, conflicts, family sociability, and democratic family style) and self-esteem and loneliness in adolescents were examined in a sample of 485 2nd-grade high school students (256 boys and 229 girls). Data were collected using three questionnaires on the loneliness, family functioning, and self-esteem of adolescents. Family functioning and self-esteem were significantly related to loneliness both in adolescent boys and girls. Adolescents experienced less loneliness when family cohesion and sociability were higher, conflicts were lower, the family style was more democratic, and self-esteem was higher. Family functioning was also related to self-esteem. The more functional the family, the higher the self-esteem of adolescents. Self-esteem played a partly mediating role in the relation between family functioning and loneliness only for boys. This emphasizes the influential role of self-esteem on loneliness.

The purpose of this study was to investigate the dietary intake, obesity index and psychosocial factors influencing obesity among 200 high school girls in Seoul. The Social Cognitive Theory provided the Conceptual basis for this study. A cross-sectional survey was conducted to examine factors related to obesity, including self-efficacy for controlling overeating, social support for eating behavior, perception of body image and weight control, nutrition knowledge, and attitudes toward obesity. The data were analyzed using t-test and multiple logistic regression. The results of this study are as follows : 1) The mean age of the girls was 16.4 years, and the rate of overweight and obesity(measured by obesity index) was 27.0$\%$. 2) The mean energy intake of subjects was 1832.3$\pm$384.0kcal. The energy derived from carbohydrates, proteins and fats was 62.7$\%$, 13.8$\%$, and 23.5$\%$, respectively. There was no significant difference between the obese and the comparison group in energy intake. 3) The result of multivariate analysis indicated that obesity had a significant relation to the perception of ideal body image, social support for eating behavior, and self-efficacy for controlling overeating(p〈0.01). As subjects preferred thinner body images(OR=0.39) and received less social support(OR=0.93), the odds of being classified as obese increased. The odds of being obese were also associated with self-efficacy, however, the relation was not strong(OR=1.04). 4) Specific social support was related to obesity among adolescent girls. As subjects received more support from family member, the odds of being obese decreased. The emotional support as well as family member's positive nutrition behavior plays a significant role. In addition, instrumental support from friends was associated with obesity. With repect to self-efficacy, the odds of being obese were increased as subjects felt less confident in controlling overeating when tempting food was placed in front of them or after an argument. In contrast, the obese group felt more confident in controlling overeating for the rest of the specific situations examined. These findings suggest that educational interventions for weight control should incorporate strategies to help participants realize their degree of obesity, to reduce the discrepancy between current and ideal body image, to elicit and maintain social support from friends and family, and to increase the self-efficacy for changing eating behaviors.

The purpose of this study was to identify dietary patterns among Korean elementary school girls based on the change in body mass index (BMI), body fat, bone mineral density (BMD), and bone mineral content (BMC) during 22 months and to explore the characteristics of dietary patterns identified. Girls aged 9-11 years were recruited and 3-day dietary data were collected four times. Subjects with a diet record of 8 or more days and anthropometric data measured at baseline and 22 months later were included (n = 198). Reduced rank regression was utilized to derive dietary patterns using a change in BMI, body fat, and calcaneus BMD and BMC as response variables. Two dietary patterns were identified: the "Egg and Rice" dietary pattern and "Fruit, Nuts, Milk Beverage, Egg, Grain" (FNMBEG) dietary pattern. Subjects who had high score on the FNMBEG pattern consumed various food groups, including fruits, nuts and seeds, and dairy products, whereas subjects in the "Egg and Rice' dietary pattern group did not. Both dietary patterns showed a positive association with change in BMI and body fat. However, subjects who had a higher score on the "Egg and Rice" dietary pattern had less of a BMC increase, whereas subjects who had a higher score on the FMBEG dietary pattern had more increased BMC over 22 months after adjusting for age, body and bone mass, and Tanner stage at baseline. Our results provide evidence that a well-balanced diet contributes to lean body mass growth among young girls.
