The purpose of this study was to analyze the physical development and health status of 5 year-old children for more effective health management of preschool children. This study carried out examinations of height, weight, hemoglobin, visual acuity & dental examination for 5 years-old preschool children in Kwang-ju up, Kwang-ju gun, Kyunggi-Do from January to February, 1996. For height and weight, the data were compared with the 1985's Korean standard and the hemoglobin and visual acuity data were compared with the Korean standard. The results were as follows. The average height for 5 year-old male children was 106.3${\pm}$4.7(cm) and that of 5 year-old female children was 105.3${\pm}$4.3(cm). Sixty seven point eight percent of male subjects registered below the 50th percentile for the Korean standard height and 79.5% of the female subjects registered below the 50th percentile for female. The average weight for 5 year-old children was 18.6${\pm}$2.6(kg) for females. Also, it is estimated that obese subjects totaled 2.7%. For the visual acuity, 18.0% of subjects had weak vision in the left eye and 16.9% in the right eye. As a result, it was advised that these children undergo further examination. It was remarkable that there were so many anemic children. Children with a hemoglobin content of less than 11.9(g/dl) totaled 47.8%. It is anticipated that the results of this study will contribute to the on-going evaluation and subsequent planning for the children health management program within the health promotion program of public health center in Kwang-ju gun.

Objectives: The purpose of this study is to estimate genetic and environmental factors, which can affect Idiopathic true Precocious puberty, and to evaluate the clinical and endocrinologic characteristics. Methods: Retrospective and Comparative analysis of 76 children (72 girls and 4 boys) has been diagnosed with idiopathic true precocious puberty, and treated with GnRHa from December 2008 to July 2011. Results: 1. The Average chronological age (CA. yr) of children diagnosed with idiopathic true precocious puberty was $8.40{\pm}0.81$ (girls), $9.93{\pm}0.12$ (boys). 2. The Average height & weight percentile (%ile) of the girls diagnosed with idiopathic true precocious puberty was $67.38{\pm}22.04$, $67.69{\pm}23.20$. 3. The girls' mothers have diagnosed with idiopathic true precocious puberty, and they were shorter than the average. This shows that mother's small height and idiopathic true precocious puberty are closely related to each other. 4. BMI percentile (%ile) of girls diagnosed with idiopathic true precocious puberty was $63.26{\pm}24.86$. 23.6% of children were diagnosed with overweight or obesity. This result shows that obesity and idiopathic true precocious puberty are proportionally related. 5. Birth weights (kg) of the children diagnosed with idiopathic true precocious puberty were $3.16{\pm}0.43$ (girls), $3.15{\pm}0.38$ (boys). 8.3% of children were diagnosed with Intrauterine growth retardation. 6. The Average bone ages (BA. yr) of the children diagnosed with idiopathic true precocious puberty were $10.51{\pm}0.99$ (girls), $12.10{\pm}0.97$ (boys). The Average BA-CA was $2.11{\pm}0.81$ (girls), $2.00{\pm}0.87$ (boys). 7. The Average predicted adults' height (PAH. cm) of the children diagnosed with idiopathic true precocious puberty was $151.61{\pm}4.00$ (girls), $163.50{\pm}2.15$ (boys). The Average MPH-PAH was $6.84{\pm}4.91$ (girls), $6.00{\pm}5.35$ (boys). 8. 23.6% of the children treated with GnRHa were co-treated with Growth Hormone. Conclusions: Estimated factors which cause Idiopathic true precocious puberty are mother's small height, obesity, and Intrauterine growth retardation. However, the studies of Oriental Medicine for Idiopathic true precocious puberty were lacking. Further clinical and experimental researches are needed.

A dietary survey of 100 children, aged 5 to 6, of Y.C. Kindergarten located in Yowido apartment compound of Seoul, was conducted July 18 to August 21, 1979. The results are summarized as follows: General family environment: Ninety four percent of the subjects were from families having two to three children, without grandparents in the home. One hundred percent of fathers were educated at or above the college level, while 83.9% of mothers had completed college. Mothers' ages ranged from 30 to 40 years, with 58% in the $31{\sim}35$ age bracket. Nearly 60% of the fathers were office and government employees, 10% were professors and teachers, 30% were engaged in businesses and other work, while 91.3% of mothers were unemployed. Anthropometric measurements: Mean values of standing height, body weight, girth of head and girth of chest, ranged from the 75th to the 90th percentile of Korean standards. None of the subjects had anthropometric indicators below the 5th percentile, representing the malnutrition borderline, of the Korean standards; while 12%, 24%, 17% and 14% of subjects supposed the 97th percentile in standing height, body weight, girth of head, and girth of chest, respectively. Furthermore, 58% of subjects exceeded Jelliffe's standard in arm circumferences; 60%, in triceps skinfold thickness; and 14.5% of subjects exceeded 120% of the latter standard. From this data, a certain number of these children were judged to he rather overweight. Dietary intake: Mean intake per day of energy and of nutrients, excluding iron, reached or exceeded Korean recommended dietary allowances. The energy input ratio of carbohydrate: protein: fat was 61.4 : 13.2 : 25.4, showing lower dependance on carbohydrates and higher dependance on fat for energy needs, compared with the average for Korean children of the same age group. Mean FAO-protein score of each subject's diet was shown to be as high as 90.6. Energy intake was divided among breakfast, lunch, and evening meal, on the average, in a ratio of 19.6 : 24.1 : 23.0. Approximately 33.3% of the daily caloric intake came from the snacks. Nutrition Knowledge of mothers: Nutrition knowledge of mothers was highly scored. Mothers' self-evaluations of their knowledge of nutrition was highly correlated with attitudes toward nutrition behavior.

Objectives The purpose of this study is to analyze the characteristic of pediatric patients who visited oriental medical hospital for growth treatment. Methods The study was conducted with 130 pediatric patients who visited ${\bigcirc}{\bigcirc}$ Korean medicine hospital from January 2016 to August 2017. The patient's data was classified by sex, age, pattern identification and diseases. The classified data was analyzed to find the correlations and characteristics among variables. Results There were 50.8% of boys and 49.2% of girls. 6.2% of the total patients were in 'early childhood', 50.8% were in 'late childhood' and 43.1% were in 'puberty' stage. In terms of pattern identification, 44.6% of the total patients were 'Spleen-lung Qi Deficiency', 53.8% were 'Lung-kidney Yin Deficiency' and 1.5% were 'Weakness of Heart and gallbladder'. 44.3% of the patients had various diseases including rhinitis (77.6% of 120.7%). Height percentile of the children with using the Growth chart of 2017 was lower than using the Growth chart of 2007. Predicted height based on the child's bone-age were higher than the predicted height based on the parental height, although both of the precited factors were correlated to the current child's height. Conclusions This study showed the characteristic of the pediatric patients who visited oriental medical hospital for growth treatment. It helps to determine prognosis and treatment, and to explain treatment measures.

Objectives: This study was performed to investigate secular trends in height, weight, obesity among Korean children and adolescents in 2006-2015. Methods: The study participants were 1,249,698 children and adolescents 6-17 years in age who participated in health examinations for school students supervised by Korean Ministry of Education and conducted by the Korea Association of Health Promotion in 2006-2015. Height and weight were measured unified procedures at each period. Obesity was defined as being 95th percentile of sex-specific body mass index(BMI) for age in the 2007 Korean National Growth Charts or $BMI{\geq}25$. Results: Between 2006 and 2015, the median of height and weight, BMI of Korean children and adolescents has increased significantly. The overall prevalence of obesity was 10.7%(boys 12.6%, girls 8.7%). In 2012-2015, the prevalence of obesity 12.2%(boys 14.1%, girls 10.2%), compared to 9.1%(boys 10.9%, 7.2%) in 2006-2008. The increase in obesity prevalence was statistically significant(p<0.05). The prevalence was highest in Gyeonggi area, lowest in Chungcheong area when compared to other regions(p<0.001). Conclusions: During the period 2006-2015, growth trends, prevalence of obesity among Korean children and adolescents increased significantly. Health promotion and intervention programs promoting healthy growth and development of Korean children and adolescents were need consider the demographic and regional characteristics.

Objectives : This study was performed to investigate the distribution of apolipoproteins A-I and B among Korean employees and their partners. Methods : The study population consisted of 7,633 men and women (4,578 men and 3,054 women) residing in Seoul and Kyung-gee Do, with an average age of $43.5{\pm}8.3$ years. Blood samples were collected following at least 12 hours of fasting. Apolipoproteins A-I and B were measured using a Behring Nephelometer analyzer. The body mass index (BMI) for each participant was calculated as weight (kg) divided by height squared $(m^2)$. Information on health-related behaviors such as exercise, alcohol intake, and smoking habits was collected through self-administrated questionnaires. Results : The mean concentrations of Apo A-I were $132.6{\pm}22.3mg/dL$ and $142.9{\pm}24.8mg/dL$ in the men and women, respectively. The concentration of Apo A-I increased significantly across all age categories of men. The mean concentrations of Apo B were $101.7{\pm}23.2mg/dL$ and $87.8{\pm}23.5mg/dL$ in the men and women, respectively, and Apo B increased significantly across all age categories for both the men and women. Exercise and BMI were major determinants for Apo A-I and B levels. The 10th percentile of Apo A-I concentration was 109 mg/dL in the men and 113 mg/dL in the women, and the 90th percentile of Apo B concentration was 131 mg/dL in the men and 118 mg/dL women. Conclusions : For the prevention of coronary artery disease, we recommend that for individuals in the 10th percentile of concentration for Apo A-I and the 90th percentile of concentration for Apo B, active preventive interventions such as weight loss and exercise should be taken. This study, within its limitations, may be useful for evaluating apolipoprotein A-I and B concentrations in Korean adults.

This survey of 180 6th-grade students was focused owl the differences of nutritional and anthropometric status according to calorie Intakes. The results were summarized as followed : 1) All nutrient intakes of boys were higher than those of girls, and both groups had lower calcium and iron intakes compared with RDA. But all the nutrient Intakes were showed significantly different among three groups divided by percentile of calorie intake(lower 25%, 25∼75% and upper 25%), therefore it suggested that subjects had a large individual variance. 2) Mean height, weight, TSK, and blood pressure of boys were 145.5cm, 40.6kg, 19.3mm, and 114.5/68.4mmHg respectively, and girls were 148.4cm, 38.9kg, 16.7mm, 112.3/67.0mmHg. The differences in anthropometric status according calorie and calcium intake were not found. This study showed protein intake had influence on height and weight of boys.

The aim of this study was to evaluate the body composition difference and obesity prevalence in grade 5 to 8 by gender. A total of 1,333 students, 707 boys and 631 girls, were recruited from one elementary and one middle school in Seoul, Korea. Anthropometric measurements including height, weight, lean body mass, and body fat were assessed. Height and weight were increased by grade, but Body Mass Index (BMI) by grade showed no significant difference among boys. Lean body mass had growth spurt between 7 and 8 grade among boys compared to gradual increase among girls. Overweight and obesity prevalence were higher among elementary schoolers than middle schoolers. Overweight (BMI for age> $85^{th}$ percentile) prevalence was about $44\%$ among $5^{th}$ grade boys compared $29\%$ among same grade girls. These results provided that there were prominent difference regarding body growth and obesity prevalence in gender and grade. Further studies for children and adolescents should be considered their body composition change.

The purpose of this study was to establish the range of the body frame size determination for elderly subjects. Anthropometric data were collected from over 60 years old 229 elderly peoples. Three methods for determining frame size were to measure elbow breadth, ankle breadth, and height to wrist circumference ratio. Among the three variables, ankle breadth exhibited the lowest correlation with skinfold thickness and changed little with age. A pairwise comparision among three methods for determining frame size showed that the highest incidence of overall agreement was achieved when the ankle breadth and elbow breadth were compared. This analysis supported that ankle breadth can be used as an indicator of frame size. Small, medium and large categories of ankle breadth were presented depending on whether the measurements were below the 15th, between the 15th and 85th, and above the 85th percentile for ankle breadth.

It is necessary to have a dummy that describes the anthropometry of a victim with accuracy. This study presents three scaled side impact dummies constructed for the use of MADYMO. They represent five, fifty and ninety-five percentile Korean males ranged from the age of 25 through 39. Thirty-five anthropometric data were used to scale input files required for MADYSCALE. Geometries, inertia, joints and other parameters for dummies were scaled based on the configurations of EuroSID-1. This study proposes the lateral impact response requirements for head, thorax and pelvis of Korean side impact dummies. A lateral drop impact test was conducted for the head at the height of 200 mm. Lateral pendulum impact tests were also carried out for thorax and pelvis at three specific impact velocities. All these test results were obtained from simulation based on MADYMO. All the procedures of the three tests followed the requirement of ISO/TR 9790.
