The hypothesis was tested that children whose families differ in socioeconomic status(SES) and educational level differ in their rates of productive language development because they have different language-learning experiences. Naturalistic interaction between mothers and their children was video taped. Transcripts of these interactions provided the basis for estimating the growth in children's productive vocabularies and properties of maternal speech. The sixty children from age 1 to 3 were selected in Yanji, China. The results show that the high educated mothers' children grew more than the low educated mothers' children in their mean length of utterances. Properties of maternal speech that differed as a function of mother's educational level fully accounted for this difference. Implications of these findings for mechanisms of environmental influence on child development are discussed.

Purpose: This study investigated the parenting experiences of mothers of young children born moderate-to-late preterm (MLPT) in South Korea. Methods: In this qualitative study, semi-structured focus group interviews were conducted with 10 mothers of MLPT children from infancy to preschool age. The interviews were video-recorded, transcribed verbatim, and analyzed using qualitative content analysis. Results: Four categories resulted from the analysis of parenting experiences of mothers with young MLPT children, as follows: "becoming a mother of an early-born child", "difficulties as the primary caregiver for a high-risk child", "helpful social support, but still a lack of professional support for parenting a high-risk child", and "mothers and children growing together". Conclusion: Mothers of young MLPT children experienced difficulties due to concerns about their child's health, growth and development, and insufficient child-rearing support. Therefore, social support systems should be strengthened and more aggressive nursing strategies should be adopted for mothers of young MLPT children.

Objectives : As obese children have been increased, the interest in the impact of obesity on growth also have been increased. This study is to examine relations between obesity and skeletal maturity by analyzing body compositions and bone age. Methods : Subjects were composed of 233 children from 6 years to 17 years of age, without any other diseases related to growth, who visited the department of pediatrics, OO oriental medicine hospital and measured their body composition (body mass index, body fat ratio, fitness score) and bone age. Results : 1. As body mass index was increased, the skeletal maturity significantly was also increased. 2. As the mean of bone maturity was increased, the BMI was increased from the underweight type to the normal type to the overweight type; the bone maturity was increased as the fat ratio was increased from the normal type to the obese type to the excessively obese type; and the bone maturity was higher in the weak, obese type than the normal type when classified according to the Fitness Score. 3. The bone maturity of the overweight group in the BMI classification and excessively obese group in the fat ratio classification significantly were increased. 4. Skeletal maturity significantly was increased in children who developed secondary sexual character. 5. The significance of obesity causing increase of the skeletal maturity was higher in boys than in girls. 6. Only in the case of children without development of secondary sexual character, obesity caused an significant increases in the skeletal maturity. Conclusions : Obesity could cause the increase of skeletal maturity, and the obesity could affect more to the boys than girls and more to the children than teenagers.

It became new social interest for children to have their own appropriate physical, mental, social environment as one independent identity, In these social atmosphere, new design method and standard of children's residence, education, playing environment which can fill their desire. When home and school are the first places to meet the world and learn, museum and science hall are the representing places to provide education and entertainment, especially to preschoolers, they are the prior education system. it is the most important these science halls to give children potential familiarity of science rather than direct knowledge. Also these places should be stepping stones of the process of intellectual growth as foundation stones for future science education. On this research i will provide a direction to space planning of children's science hall, extended to children' museum studying display producing of playing conception, the necessary element of children's physical, mental, social behavior development process.

Sotos syndrome (SS, OMIM 117550) is characterized by prenatal and postnatal overgrowth with multiple congenital anomalies. However, there have been few cases of growth retardation caused by renal failure from infancy. We report a case of dysplasia of the bilateral kidneys with renal failure and poor postnatal growth. A 2-month-old boy visited the emergency room owing to poor oral intake and abdominal distension. He was born at the gestational age of 38 weeks with a birth weight of 4,180 g. After birth, he had feeding difficulty and abdominal distension. Upon physical examination, his height and weight were in less than the 3rd percentile, while his head circumference was in the 50th percentile on the growth curve. He also showed a broad and protruding forehead and high hairline. Blood laboratory tests showed severe azotemia; emergent hemodialysis was needed. Abdominal ultrasonography revealed bilateral renal dysplasia with multiple cysts and diffuse bladder wall thickening. A posterior urethral valve was suggested based on vesicoureterography and abdominal magnetic resonance findings. Results of a colon study to rule out congenital megacolon did not reveal any specific findings. The conventional karyotype of the patient was 46, XY. Array comparative genomic hybridization study revealed a chromosome 5q35 microdeletion including the NSD1 gene, based on which SS was diagnosed. We describe a case of SS presenting with end stage renal disease due to posterior urethral valve. The typical somatic overgrowth of SS in the postnatal period was not observed due to chronic renal failure that started in the neonatal period.

Children from low-income families are vulnerable to variable psychological and emotional stress related to financial issues and dysfunctional families. The subjects were 15 1st to 3rd graders who were low on the Self Esteem Scale (SES). They were attending an after-school center for elementary school students. They participated in three art therapy groups from April to October 2005. Children's depressive symptoms and self-esteem were assessed using the Children's Depression Inventory (CDI) and an observational check-list. Results showed that the group art therapy program brought about significant effects on increasing self-esteem of the children and reducing depressive symptoms, showing that group art therapy can facilitate emotional and psycho-social growth of children from low-income families and can be developed in family-based community programs.

Purpose : This study was performed to determine the developmental expression pattern of nerve growth factor(NGF) in the urine of healthy children. It was hypothesized that NGF may contribute to the development of the spinobulbospinal micturition reflex that represents the adult micturition pattern. Methods : Voided urine was collected in 60 healthy children during the first 5 years of life(0-1 month, n=10; 1 month-1 year, n=10; 2 years, n=10; 3 years, n=10; 4 years, n=10). The urinary NGF was analyzed by using an enzyme linked immunosorbent assay. Results were normalized based on creatinine or total protein in urine. Results : NGF was significantly greater among neonates compared to other age groups(P<0.05). NGF levels declined during 1 month to 1 year and increased by age 2 years. NGF levels at age 3 years were less than in neonates examined. When comparing the NGF levels according to continence in children over 1 year old, NGF levels were significantly lower in children with continence than in children with incontinence(P<0.05). Conclusion : These data suggest that NGF is involved in the achievement of continence and in mechanisms of bladder nerve growth and in the reorganization of bladder reflex pathway.

Purpose: The present study assessed the role of an amino acid-based formula (AAF) in the growth of infants with cow's milk protein allergy (CMPA). Methods: Non-breastfed, term infants aged 0-6 months with symptoms suggestive of CMPA were recruited from 10 pediatric centers in China. After enrollment, infants were started on AAF for two weeks, followed by an open food challenge (OFC) with cow's milk-based formula (CMF). Infants with confirmed CMPA remained on AAF until 9 months of age, in conjunction with a cow's milk protein-free complementary diet. Body weight, length, and head circumference were measured at enrollment and 9 months of age. Measurements were converted to weight-for-age, length-for-age, and head circumference-for-age Z scores (WAZ, LAZ, HCAZ), based on the World Health Organization growth reference. Results: Of 254 infants (median age 16.1 weeks, 50.9% male), 218 (85.8%) were diagnosed with non-IgE-mediated CMPA, 33 (13.0%) tolerated CMF, and 3 (1.2%) did not complete the OFC. The mean WAZ decreased from 0.119 to -0.029 between birth and enrollment (p=0.067), with significant catch-up growth to 0.178 at 9 months of age (p=0.012) while being fed the AAF. There were no significant changes in LAZ (0.400 vs. 0.552; p=0.214) or HCAZ (-0.356 vs. -0.284; p=0.705) from the time of enrollment to age 9 months, suggesting normal linear and head growth velocity. Conclusion: The amino acid-based study formula, in conjunction with a cow's milk proteinfree complementary diet, supported normal growth till 9 months of age in a cohort of Chinese infants with challenge-confirmed non-IgE-mediated CMPA.

This study aimed to explore the trajectories of computer game use of school age children and to identify the related predictors. The data for this study used Korean Children and Youth Panel data covering from the second year to the sixth year of elementary school. A total of 1,959 participants were analyzed. Latent class growth model was employed to explore the trajectories of computer game use and multinomial logistic regression was conducted to identify the significant predictors. Main results indicated that three types of trajectories were identified: low game using group, high initial using-fluctuating group, and high increasing game using group. Each group was found to be associated deferentially with sex, aggression, attention deficit, main caregiver's education, siblings, parent absence after-school, neglecting, family income, family trip, school grades, and peer relationship. Based on these findings, this study emphasized the importance of predictive intervention for the game user among early school age children and suggested useful practical strategies.

The purpose of this study was to get adequate substitute snacks for atopic dermatitis children. For this purpose food preference was surveyed by questionnaires to atopic dermatitis children in the kindergarten of Incheon area. As a result, anthropometric measurements were not significantly different by gender Most of atopic children were severe malnutrition by Rohrer index average 1.375. $13.3\%$ of atopic dermatitis started during newborn baby. $62.3\%$ of atopic dermatitis symptom started from 7 months to 3 years old. $48.9\%$ of atopic children didn't know the causes of the symptom. Though parents didn't thought instant/retort food, fried food, egg, snacks, milk were good for atopic dermatitis, they have offered egg, milk, meat, mackerel to their atopic dermatitis children for growth. Snacks of atopic dermatitis children were positively correlated between children's eating and favorite snacks(r=0.84), children's eating and parents' wishing snacks (r=0.615) and children's favorite and parents' wishing snacks(r=0.23). Therefore $83.7\%$ of atopic dermatitis children and their parents wanted reliable processed foods, $83.3\%$ of them despite high cost.
