In order to know cephalometric norms for the preschool children, this roentgeno cephalometric study was undertaken in each 50 Korean male and female children of primary dentition age from 4 to 5 year. The following results were obtained. 1. In the skeletal analysis, there was no significant difference between male and female in angular measurement and the linear measument of the male was generally greater than that of the female. 2. Saddle angle was $122.3^{\circ}$, articular angle was $147.6^{\circ}$, gonial angle was $119.4^{\circ}$ and the sum of each angle was $396.1^{\circ}$ in male and $396.6^{\circ}$ in female. 3. The ratio of mandibular body to anterior cranial base was about 1 : 0.91. 4. In the primary dentition, suggested that the nasion and point A move forward relative to sella turcica in a fashion, pogonion and point B are equal in angular position relative to plan S-N, bony chin and chin button was yet underdeveloped, and the forward growth of mandible was seen rapid than maxilla after 4 years. 5. Suggested that the percentage of anterior facial height to the posterior facial height were 64.4% in male and 64.1% in female. 6. Maxillary primary incisors was more upright than the permanent incisors, mandibular primary incisors was inclined lingually relative to the permanent incisor, and primary incisors was more upright than the permanent incisors. 7. Maxillary primary incisors in female was inclined labially than male. 8. In the the relationship of the upper lip and lower lip to the esthetic line, the upper lip was 2.11mm and the lower lip was 2.33mm front of the esthetic line.

Purpose: This study examined the distribution of the body mass index (BMI) according to gender and age among Korean children and adolescents to compare the distributions of being underweight, normal, overweight, and obese using both Korean and international criteria. Methods: This secondary data analysis utilized the data of the 2016 Korean National Health Examination for School Students Height, weight, and BMI distributions among children and adolescents were analyzed using descriptive statistics, and the differences in BMI distribution according to gender and age were analyzed using chi-square tests. Differences in the mean BMI according to the Korean Centers for Disease Control (KCDC), the World Health Organization (WHO), and the International Obesity Task Force (IOTF) criteria were analyzed using ANOVA. Results: Using the IOTF criteria, the prevalence of underweight, overweight, and obesity among grades 1-12 students was 6.7%, 20.8%, and 7.1%, respectively; 1.6%, 21.3%, and 11.8%, respectively, according to the WHO criteria; and 5.8%, 10.1%, and 13.0%, respectively, according to the KCDC criteria. Conclusion: It is recommended to use the IOTF criteria for health promotion programs to target underweight children and adolescents while the WHO and KCDC criteria should be used for health programs for treating obese people.

The purpose of this study was to measure the nutrition knowledge, dietary attitude, eating behavior, physical ability and locomotion of 5-year-old-children, and thereby to provide the fundamental information necessary to develop a nutritionrelated physical education program. A survey was performed on 143 5-years-old boys and 113 girls. The results were as follows. The average score in the nutrition knowledge item, was 7.22 out of a possible 10 points; in the dietary attitude item, 32.46 out of 50 points; in the eating behavior item, 26.67 out of 40 points. According to body measurement, there was a significant difference in height by gender (p<0.05), Significant differences in muscle mass and basal metabolic rate were also observed by gender (p<0.001). Gender also influenced the flexibility and reflexibility (p<0.001), with significant difference in balance of the right side (p<0.01). Although this study was limited by its cross-sectional study design, the body muscle (p<0.05) and basal metabolic rate (p<0.05) were observed to have a positive relation with nutritional knowledge. In addition, there was a significant positive correlation between nutritional knowledge and dietary attitude (p<0.01). According to the results, it is necessary to develop a long-term and systematic program with the combination of nutrition and physical education to develop correct dietary habits and for the balanced growth of children.

Currently, there is a gradual increase in double-income households in our country, and one-child families gradually become the norm as well due to a decrease in the birth rate. The purpose of this study was to examine the characteristics of spatial use and furniture arrangements in the residential spaces of one-child double-income households in an effort to be of use for spatial planning suitable for their living. 30 cases of double-income households whose children's ages ranged from infancy to secondary school years were visited to have in-depth interviews and make on-site inspections. The findings of the study were as follows: First, the most common spatial use pattern for three bedrooms was using one for the parents, another for their child and the third for personal computers and clothing storage. It signified that the parents and their child used one room respectively, and that there were personal computers and clothing in the third room. Second, as for the pattern of using the rooms according to furniture arrangements, there were great disparities in that regard according to child age. It implies that there were differences in their living and needs for furniture arrangements according to their children's growth. The findings of the study made it possible to determine the state of living in the double-income households in detail, and suggest that differentiated house planning is required depending on children's age groups.

This study aims to examine developmental trajectories and predictor variables of problem behaviors and school adjustment trajectories among children from low-income families using latent growth modeling. The data was collected from the 2nd year to the 4th year (2012-2014) of a community child center child panel survey conducted by the National Youth Policy Institute. The major findings are as follows. First, as the grade went up, the problem behaviors of children from low-income families increased while school adjustment decreased. Second, multi-level domains, such as individual, school, and family variables influenced school adjustment trajectory, while only individual variables, such as depression, isolation, and motivation for achievement influenced problem behavior trajectory. Third, common protective factors between problem behaviors and school adjustment trajectories were motivation for achievement in and satisfaction of the community child center. Common risk factors between problem behaviors and school adjustment trajectories were isolation and aggression. Based on the results, the implications for child welfare practices were discussed.

In this study, John Burningham's picturebooks(『Come Away from The Water, Shirley』, 『Time to Get Out of The Bath, Shirley』) was analyzed using the concept of carnival among Bakhtin's conversationalism theory. In John Burningham's picturebooks, the unconscious desire for the deviation of the main character, Shirley, is transformed into an adventure in an extraordinary imaginary world, and is depicted as a festival with laughter. Through picturebooks, children are satisfied by indirectly experiencing the forbidden behavior in reality by converting it into an event in the imaginary world. This indirect experience is very important for children to naturally resolve their dissatisfaction in reality and to develop their own original inner development. This study also suggests that providing an environment where children can easily access various picturebooks at home or early childhood education institutions plays a very important role in their growth.

Variation in the facial pattern and effect of the rotational jaw growth on the facial proportion were studied in serial cephalometric radiographs of 40 Korean children (25 boys, 15 girls) ranging in age from 6 to 13 years. According to Y-axis (N-S-Gn) growth change during the 7 years of period, the subject who had exhibited 'wave-like' manner of Y-axis growth change within ${\pm}\;2^{\circ}$ was classified to the Parallelwise group and the subject who had exhibited Y-axis increase more than $+2^{\circ}$ was classified to the Clockwise rotation group and the subject who had exhibited Y-axis decrease more than $-2^{\circ}$ was classified to the Counterclockwise rotation group. For the comparison of each group, a total of 22 morphologic variables were employed and the data were analyzed by means of computer morphometrics and statistical methods. On the basis of the finding of this study, the following trends were established. 1. The Parallelwise group was $75\%$, the Clockwise rotation group was $12.5\%$ and the Counter-clockwise rotation group was $12.5\%$. 2. The growth pattern of cranial base was related to the rotation of mandible. 9. Maxillary prognathism was occured in the Counterclockwise rotation group and the rotation of palatal plane was occured in the Clockwise rotation group. 4. Mandibular prognathism was occured in the Parallelwise and the Counterclockwise rotation groups, especially in the Counterclockwise rotation group. 5. The degree of maxillo-mandibular divergency was constant in the Clockwise rotation group but decreased in the Counterclockwise rotation and the Parallelwise groups, especially in the Counterclockwise group. 6. There were no differences in the size of the anterior upper facial height (N-ANS) and the posterior lower facial height ((Go-Me)-PNS) but there were differences in the size of the anterior lower facial height (ANS-Me) and the posterior upper facial height ((S-N)-PNS) between each group. 7. The growth increment and the size of the facial depth was not related to the growth pattern of the face but the growth increment and the size of the facial height was related to the growth pattern of the face. 8. Proportional change due to the facial growth rotation was concentrated in the anterior lower face. 9. The most apparent difference between each group was happened in the size of the posterior cranial base (S-Ba) and the facial length (S-Gn).

Before 1970, mandibular overgrowth was known as main cause of skeletal Class III malocclusion in growing children ; however, recent study reports that many skeletal Class III malocclusion patients also show maxillary deficiency. Since 1972, when Delaire re-accommodated Protraction Head Gear (P.H.G.), many researchers have reported that skeletal Class III discrepancies could be corrected through use of P.H.G., which induces anterior movement of maxilla and change in mandibular growth pattern into infero-posterior direction ; nevertheless, it is very difficult to predict resultant changes of orofacial region. The purpose of this study was to find out what treatment effect P.H.G. has on different study samples. Author divided 51 skeletal Class III malocclusion patients with maxillary deficiency who were treated with P.H.G. into different study groups depending on sex, treatment beginning age, intraoral appliance, and facial growth pattern. By doing so, following results were obtained. 1. Treatment beginning age and Sex Four age groups (5.8 to 8 year-old, 8 to 10 year-old, 10 to 12 year-old, 12 to 14 year-old) were compared, and no significant difference was observed. (p<0.05) There was no significant difference between the sex groups, either. (p<0.05). 2. Intraoral appliance Treatment effects of study groups that used R.P.E.(mean age of 10.2) and Labio-Lingual appliance(mean age of 8.9) were compared. There was no significant difference depending on the type of intraoral appliance that was used. (p<0.05) 3. Facial growth pattern 1) Amounts of SNB and ANB corrections were smaller in clockwise growth pattern group than those in normal or counterclockwise growth pattern group. (p<0.05) 2) Amounts of increase in Wits appraisal and mandibular plane angle were greater in counterclockwise growth pattern group than those in normal or clockwise growth pattern group. (p<0.05) 3)Amounts of increase in articular angle were greater in counter lockwise growth pattern group than those in clockwise growth pattern group. (p<0.05)

Purpose: This study aimed to evaluate the time trends of waist circumference (WC) and waist-height ratio (WHR), and to present WC and WHR distributions with optimal WHR cutoff for abdominal obesity in Korean children and adolescents. Methods: We performed a retrospective cross-sectional analysis of data from 13,257 children and adolescents (6,987 boys and 6,270 girls) aged 6-18 years who were included in the third to sixth Korea National Health and Nutrition Examination Survey (KNHANES, 2005-2015). Linear regression analyses were used to identify secular changes in WC and WHR by age, sex, and KNHANES waves. A receiver operating characteristic curve analysis was used to determine the optimal WHR cutoff values for abdominal obesity and cardiometabolic risk factors. Results: The mean WC and WHR distributions from 2005 to 2015 showed no significant secular changes between the KNHANES 4 waves (P for trend ${\geq}0.05$ in all ages and both sexes). The mean WCs in the present study were lower than those in the 2007 Korean National Growth Charts. The mean WHR at ages <13 years was statistically higher in the boys than in the girls, but did not significantly differ between the sexes among those aged 13 to 18 years. The optimal WHR cutoff for abdominal obesity was 0.48 (area under the curve, 0.985; 95% confidence interval, 0.985-0.985) in the 13- to 18-year-old adolescents. Conclusion: WC and WHR showed no secular changes over 10 years. The optimal WHR cutoff for abdominal obesity of 0.48 is useful for diagnosing and managing obesity and thus preventing obesity-related cardiometabolic complications in 13- to 18-year-old Korean adolescents.

This research has been attempted to measure health acknowledgement and needs of 1158 respondents, the parents of elementary, middle, and high school students, residing in Seoul and In-chon. 1. The majority of parents had high interests in health and their children's health education. In addition, more than half of parents showed positive responses in their willingness to participate in organizational activities. 2. 41.7% of parents thought that their children were receiving health education regularly. For their recognitions of the course title, 'Physical Education' was the most highly recognized by the parents of elementary and middle school students, and 'Military Drill' for the parents of high school students. 3. A high number of parents perceived the problems of school health education. 4. There was a high number of parents, who thought that health education teachers' knowledge was deficient, and 86.3% of them agreed that additional education for 33the teachers should be desired. 5. 95.5% of parents acknowledged the necessity of health education; 78.8% of them recognized the reinforcement of health education; and 60.0% of them percepted the necessity of establishing the independent health education courses. 6. For the matter of instruction period, the majority of parents responded that health education should be taught from "kindergarten" and "elementary school". For the appropriate instruction hour per a week, the majority answered 1 hour. Most respondents answered that those, who majored in health education, should be the appropriate teachers. 7. The survey result indicated that there was a close correlation between the cognition of the importance of health education and the correspondents' health educational background, their interest and willingness to participate in health education. 8. The most desired areas of health education were Safety Education and Health-Habit. The followings were Environmental Health, Prevention of Disease, Mental Health, Growth and Nutrition, and Drug-Abuse in a sequent order. The parents of elementary school students showed a high acknowledgement on Health-Habit, Growth and Nutrition, and Prevention of disease, Safety Education. On the other hand, as the children entered into the advanced schools, the parents' recognition of the health education needs shifted into Sex education, Drug Abuse, and Mental Health. 9. Those respondents, who recognized the necessity of health education and advocated the establishment of independent health education courses, had a strong demand for the implementation of the health education.
