Growth charts are curves or tables that facilitate the visualization of anthropometric parameters, and are widely used as an important indicator when evaluating the growth status of children and adolescents. The latest version of the Korean National Growth Charts released in 2007 has raised concerns regarding the inclusion of data from both breastfed and formula-fed infants, higher body mass index (BMI) values in boys, and smaller 3rd percentile values in height-for-age charts. Thus, new growth charts have been developed to improve the previous version. The 2006 World Health Organization Child Growth Standards, regarded as the standard for breastfed infants and children, were introduced for children aged 0-35 months. For children and adolescents aged 3-18 years, these new growth charts include height-for-age, weight-for-age, BMI-for-age, weight-for-height, and head circumference-for-age charts, and were developed using data obtained in 1997 and 2005. Data sets and exclusion criteria were applied differently for the development of the different growth charts. BMI-for-age charts were adjusted to decrease the 95th percentile values of BMI. Criteria for obesity were simplified and defined as a BMI of ${\geq}95th$ percentile for age and sex. The 3rd percentile values for height-for-age charts were also increased. Additional percentile lines (1st and 99th) and growth charts with standard deviation lines were introduced. 2017 Korean National Growth Charts are recommended for the evaluation of body size and growth of Korean children and adolescents for use in clinics and the public health sector in Korea.

After the WHO Growth Standards (WHOGS) was published in 2006, many countries in the world endorsed and adopted the new growth references as a standard measure for the growth of infants and young children. Certainly, the WHOGS has an impact on the global policy about obesity and underweight in children. Such WHOGS innovation has influenced many regional health authorities and academies, which have managed their own growth charts for a long time, in changing their strategies to develop and use regional growth charts. In Korea, along with the tradition to create a national growth chart every decade, we now face a new era of advancing with the WHOGS.

목 적 : 1967년 이후로 1998년까지 대한소아과학회와 정부는 매 10년마다 한국 소아청소년 신체발육표준치를 제정하여 왔다. 지난 40년간의 한국 성장도표는 체계적이고 통계학적인 표준화를 거치지 않은 기술적인 도표였다. 전 세계적인 비만의 유행에 대하여 WHO나 CDC와 같은 국제적인 기관들은 이에 대처하기 위하여 성장도표의 제정 원리들을 변경하여 왔다. 본 논문은 고찰과 함께 새로운 2007년 성장도표 개발과정을 요약하였다. 방 법 : 질병관리본부 만성병조사과의 주도로 2005년에 새로운 성장도표 제정을 위한 신체계측 조사를 시행하였고, 그 결과 소아 비만의 급증과 청소년 최종 성장의 세대별 증가 현상이 정체된 것을 확인하였다. 이에 연구진은 혁신적인 방법론을 도입하였으며, 이를 통하여 새로운 성장도표를 제정하였다. 확보 가능한 원자료인 1997년 및 2005년 측정 자료를 표준화고 통합하였으며, LMS 방법을 도입하여 통계적 모델링을 시행하였다. 결 과 : 표준화된 자료로서 연령별 신장, 연령별 체중, 연령별 체질량지수, 연령별 두위, 신장별 체중 도표가 제공되며, 2005년 조사의 표준화되지 않은 자료로 제공되는 연령별 허리둘레, 연령별 가슴둘레, 연령별 상완둘레, 연령별 피부 두겹집기가 제공된다. 임상 지침도 함께 제공된다. 결 론 : 새로운 한국 성장도표의 개발 과정과 결과는 국제적인 기준인 WHO 표준성장도표 및 미국 CDC 성장도표의 방법론을 적용한 것으로서, 비만과 성 발육이 가속화된 현 상황에 적절하다. 이는 특히 한국 국민과 한민족에게 유용하다. 향후 보다 과학적인 표준을 제시하기 위하여 지속적인 연구가 요청된다.

Food habit forming the basis for a lifetime of food and nutrient intake is established in early childhood and has an effect to the child's growth, sociality, and obesity. A variety of nutrition screening tools exists for assessing the health and nutrition status of children such as the Growth Curve, for determining if growth is appropriate. Body mass index(BMI) as a more reliable index of overweight to prevent childhood obesity, and Nutrition Quotient(NQ) and eating behaviors questionnaire for young children and parents to estimate their nutrient intake adequate or not. Such tools are mainly used by health practitioners, such as doctor and dietitian to provide nutrition intervention services to children at risk, especially and are not easy to use for general parents, who need assessment at any time and at any place. We propose Growth Assistance System for infants and children, which is possible to assess their physical condition, nutritional status, and eating behavior integrated. To be convenient and portable, it is implemented over the smartphone as an application. The system offers the growth charts, the BMI curves, NQ and eating behavior questionnaire to take a monitoring and the functionalities operate well. We hereby expect this system support the normal growth and development of infants and young children. And also support for the health practitioner (dietitians and nutritionists) to take a role in providing nutrition counseling and education to children needing nutrition services.

In order to assess the validity of fatigue crack arrest design charts obtained from our previous numerical approach to fatigue crack arrest condition, an extensive fatigue crack growth/arrest test was performed using CT-type integrally stiffened panels. The results are presented as fatigue crack growth rate and non-dimensional crack length relationship, and these are compared with numerically simulated crack growth rates. The measured values of da/dN at the moment of fatigue crack arrest occurred in stiffened panels are good agreement with those numerically simulated crack growth rates.

To demonstrate the feasibility of utilizing FCAD chart proposed in our previous work, series of crack growth/arrest behavior in the integrally stiffened panels were simulated by numerical method using upper mentioned FCAD charts and a new crack growth rate equation. It is concluded that proposed family of FCAD curves, in the form of non-dimensional arrest load ranges, are reliable indicators of fatigue crack growth/arrest behavior of integrally stiffened panels considered here.

Purpose: The purpose of this study was to evaluate the physical growth and developmental status of infants and children of married immigrant women. Methods: The participants were 92 infants and children aged from birth to 6 yr whose mothers were married immigrant women living in one rural area. Physical growth and developmental status were evaluated by using anthropometric assessment, and Korean Denver II developmental screening test. Results: Of the participants, 10.8% were below the 3rd percentile for weight, 13.0% for length, 5.4% for head circumference, and from 69.6% to 79.3% were distributed below the 50th percentile on growth charts. Further, 18.5% were classified as having questionable development. Factors related to low physical growth in infants and children were mother's weight and mother's level in Korean language classes. Conclusion: The physical growth and developmental status of children is vulnerable and serious. The study results suggest a need for regular growth and developmental evaluations. Political support is important for these mothers. In addition, there also is a need to develop early intervention strategies to promote growth and development of the infants and children of these married immigrant women.

Purpose: This study aimed to investigate the clinical features of macrocephaly at birth in Korea using ultrasonography. Methods: We retrospectively investigated the medical records of full-term birth neonates in Cheil General Hospital & Women's Healthcare Center from January 2000 to June 2012. The following parameters were recorded and analyzed: gestational age, sex, birth weight, height, occipitofrontal circumference (OFC), physical examination, perinatal problems, and ultrasonography results. Macrocephaly was diagnosed when the OFC was greater than two standard deviations, based on the 2007 Korean National Growth Charts. Results: There were 75 neonates with macrocephaly at birth (52 boys and 23 girls), with a mean OFC of $38.1{\pm}0.49cm$. A comparison of the birth weight and height with the OFC value showed that height was correlated with OFC (r=0.35) but birth weight was not correlated with OFC (r=0.06). There were no remarkable findings in 56 cases (75%). Germinal matrix hemorrhage was identified in 10 cases (13%). An enlarged cerebrospinal fluid space was found in 5 cases (6.7%). There were 3 cases of mega-cisterna magna (4%), 1 case of ventriculomegaly, and 1 case of an enlarged interhemispheric space (6 mm) among these patients. In addition, a choroid plexus cyst was seen in 1 case. Mineralizing vasculopathy in both basal ganglia with no evidence of congenital infection was found in 2 cases and an asymptomatic subarachnoid hemorrhage was found in 1 case. Conclusion: Our results indicate that macrocephaly at birth has benign ultrasonography findings and shows a pattern of male dominance.
