The nutritional status of 125 preschool children(Female : 56, Male : 69) residing in low income area of Seoul was surveyed. The mean family size was 4.3 and the mean monthly income was 921,000 won which was below the poverty level. Average heights of boys aged 3, 4, 5 and 6 were 98.6cm, 106.1cm, 111.9cm and 116.0cm and those for girls were 99.4cm, 106.4cm, 110.9cm, and 116.0cm, respectively. There was no significant difference between the height of boys and girls. The proportion of children showing stunted growth(<90% of Korean standard of height) was 3.2%. The mean weight of boys for each age group(3, 4, 5, 6) were not significantly differient from that of girls. The proportion of children assessed as moderately underweight (<80-90% of Korean Standard of weight) was 10.4% and 3.2% of children was underweight(<80% of weight standard). The group of children aged 3 were taking adequate energy, whereas the mean energy intake of children aged 4.5 and 6 were within 77.3-78.6% of RDA. The proportion of energy derived from carbohydrate, fat and protein was 60.1%, 24.6% and 15.3%. The high proportion of energy derived from fat seems partly due to high energy intake from fat in the snack. The nutrients which did not meet 75% of the RDA were vitamin A and calcium for children aged 5, and iron for children aged 3 to 5. Carbohydrate intake was positively correlated with the height, weight and girth of chest(P<0.05-P<0.001). There was positive correlation between protein intake and weight, girth of chest and BMI, respectively(P<0.05). Iron intake showed positive relationship with height, weight and BMI(P<0.05).

This study aimed to identify the development pattern of final stop consonant perception using the gating task. Sixty-four subjects participated in the study: 16 children aged 4 years, 16 children aged 5 years, 17 children aged 6 years, and 15 adults. One-syllable words with consonant-vowel-consonant(CVC) structure, mokㄱ-motㄱ and papㄱ-patㄱ were used as stimuli in order to remove the redundancy of acoustic cues in stimulus words, 40ms-length (-40ms) and 60ms-length (-60ms) from the entire duration of the final consonant were deleted. Three conditions (the whole word segment, -40ms, -60ms) were used for this speech perception experiment. 48 tokens (4 stimuli ${\times}3$ conditions ${\times}4$ trials) in total were provided for participants. The results indicated that 5 and 6 year olds showed final consonant perception similar to adults in stimuli, papㄱ-patㄱ and only the 6-year-old children showed perception similar to adults in stimuli, 'mokㄱ-motㄱ. The results suggested that younger typically developing children require more acoustic information to accurately perceive final consonants than older children and adults. Final consonant perception ability may become adult-like around 6 years old. The study provides fundamental data on the development pattern of speech perception in normal developing children, which can be used to compare to those of children with communication disorders.

The purpose of this study was to investigate the relationship between parent's conflict, paternal/ maternal grandmother's psychological support and school-aged children's well-being. The subjects were 227 6th grade school-aged children in elementary school who were 128(56.4%) boys and 99(43.6%) girls. Instruments used in this research were CDI(Children's Depression Inventory), CPIC(The children's perception of interparental conflict scale), and psychological support scale. The data were analyzed by simple regression, standard multiple regression and hierarchical multiple regression(using SPSS 12.1). Major findings were as follows: (1) There was no difference in maternal grandmother's psychological support and paternal grandmother's psychological support. (2) Maternal grandmother's psychological support was more important variable affecting school-aged children's well-being than paternal grandmother's psychological support. (3) Paternal/maternal grandmother's psychological support operated as a main effect with school-aged children's well-being increasing as paternal/maternal grandmother's psychological support increased. There were not interaction effects of parent's conflict and paternal/maternal grandmother's psychological support on school-aged children's well-being. That result showed that paternal/maternal grandmother's psychological support did not moderate negative effects of parent's conflict on school-aged children's well-being.

The purpose of this study was to determine biochemical parameters related to protein and immunity. Subjects were 125 preschool children(M:69, F:56) residing in low income area of Seoul. Mean serum total protein of the children aged 6 was 7.3g/dl which was significantly higher than 6.6g/dl of the group aged 3. The mean serum albumin was 4.7g/dl for 3, 4, 5 age group, and 4.9g/dl for 6 age group and there was no significant difference. Serum retinol binding protein(RBP) is used as a sensitive indicatior of protein, because it tends to fall rapidly in response to protein status and respond to quickly dietary treatment. Mean RBP for each group(3, 4, 5 and 6 age group) were $2.5\mu{g}$/dl, $2.9\mu{g}$/dl, $2.7\mu{g}$/dl, $3.0\mu{g}$/dl. The Proportion of children whose RBP was than $2.6\mu{g}$/dl was 15.9%, 19.2%, 24.3% and 16.7%, respectively. The 24-hour urinary excretion of hydroxyproline was 7.9mg, 14.6mg, 11.7mg and 11.8mg for each group and the mean excretion of all children was 12.2mg/day. Children aged 3 were excreting significantly lower amount of hydroxprolinc per day than the children aged 4. The mean hydroxyproline index were 2.18, 2.39, 2.52, 2.80 for each age group and the mean of a group aged 6 was significantly higher than that of the group aged 3. The proportion of children assessed as malnourished and impaired growth(hydroxyproline index <2.0) was 18.8%, 4.9%, 2.5% and 4.3%, respectively. The nutrients which showed significant relationship with protein and immunity parameters were niacin, vitamin C and calcium. Vitamin C showed significant positive relationship(p<0.05-p<0.01) with serum RBP, total protein and globulin. The triceps skinfold thickness was significantly and positively correlated with serum globulin. Serum IgG showed significant positive relationship with height, weight, girth of chest and midarm circumference(p<0.05-p<0.01).

The Korean Metaphonological Assessment, adapted from the Metaphonological Abilities Battery (MAB; Hesketh, 2000b) was administered to examine the development of metaphonological skills of 60 normally developing Korean pre-school children aged from 3 to 6. The tasks were specifically designed to evaluate their skills to detect rhymes, onsets, and segments. A gradual improvement of total scores was observed in children from 3 to 5, with evidence for developmental refinements of metaphonological abilities in the ages of 5 and 6. Subjects were found to develop segmenting skills at a relatively early age and gradually progressed toward detecting onsets and then rhymes. The differences in the order of development from the previous studies with English-speaking children were discussed. This preliminary study also aimed to provide foundational information for investigating the link between expressive phonological impairments, metaphonolgocial skills, and literacy in Korean-speaking children.

Purpose: This study aimed to investigate problem behavior and its related factors in school-aged children. Methods: A descriptive correlational study was conducted with 221 mothers of children at 1st to 6th grades. Data were collected from March to April, 2015 using self-report structured questionnaires. Questionnaires included characteristics of subjects, Korean Child Behavior Checklist for measuring problem behavior and Children's Sleep Habits Questionnaire for assessing sleeping habits. Collected data were analyzed by independent t-test, $x^2$ test, and multiple logistic regression. Results: In logistic regression analysis, having any maternal job (aOR=2.8, 95% CI=1.1~6.9) and higher daytime sleepiness (aOR=2.9, 95% CI=1.2~7.4) were statistically significant contributors of internal problems. Higher bedtime resistance (aOR=2.2, 95% CI=1.0~4.9) and higher daytime sleepiness (aOR=2.8, 95% CI=1.2~6.3) were statistically significant contributors of external problems. Higher bedtime resistance (aOR=4.3, 95% CI=1.5~12.4) was statistically significant contributors of total problem behavior. Conclusion: School-aged children with sleeping problem are at risk for problem behavior. More attention is need to consider sleeping habits for supporting behavioral improvement in school-aged children.

The purpose of this study is to investigate the effect of parenting behavior and parent-child communication on internet use among school-aged children. The subjects were 215 children whose grade are 3rd and 5th selected from an elementary school in Incheon. The statistics used for this data were t-test, one-way ANOVA(Duncan's test), and stepwise regression. The findings from the present study suggested that academic achievement and birth order turned out to be significant variables on children's internet use, except for sex and grade. Results of the stepwise regression analyses that the etiologic model of this study was more proper, and parenting behavior is more effective variable than parent-child communication in predicting internet use among school-aged children. Implications based on this study are as follows; In order to decrease the degree of school-aged children's internet use, parents should do less permissive parenting behavior and problematic communication with their children.

This study investigated the effect of parental behavior and school adjustment on the depression of school aged children. The subjects were 386 6th graders (206 boys and 180 girls) from 6 elementary schools in Seoul and Kyoung-gi Province. Questionnaires were used to investigate the children's depression, school adjustment and parental behavior. Data were analyzed by SPSS-WIN program, including mean, standard deviation, correlational analysis, ANOVA, and regression. Results were as follows. (1) The children who perceived their parents' support and warmth as higher were less depressive than those who perceived them as lower. (2) The children who were good at school were less depressive than those who were not. (3) There were interaction effects of the children's school adjustment and parental behavior perceived by children on their depression. The regression analysis showed that the children's school adjustment was more influential on the depression of school aged children than the parental behavior perceived by children.

Purpose: Acute respiratory infection, particularly pneumonia, is the most common cause of hospitalization and death among children in developing nations. This study aimed to investigate the characteristics of children and adolescents with pneumonia who visited Emergency Department (ED) in South Korea in 2012. Methods: We analyzed National Emergency Department Information System (NEDIS) records from 146 EDs in South Korea for all pediatric patients aged ${\leq}18years$ who were diagnosed with pneumonia between January and December 2012. Results: Among 38,415 subjects, the male-to-female ratio was 1:0.8. Patients aged <12 months comprised 18.0% of the study population; those aged 1 to 3 years, 54.4%; those aged 4 to 6 years, 16.8%; those aged 7 to 12 years, 7.4%; and those aged 13 to 18 years, 3.4%. Presentation rates were highest in April, followed by January, March, and May. The hospital admission rate was 43.5%, of which 2.6% were in intensive care units. The mortality rate was 0.02%. Based on the International Classification of Diseases, 10th Revision, diagnostic codes, the types of pneumonia according to cause were viral pneumonia (29.0%), bacterial pneumonia (5.3%), Mycoplasmal pneumonia (4.5%), aspiration pneumonia (1.3%), and pneumonia of unknown origin (59.3%). Conclusion: Despite the limited data due to the ED data from the NEDIS lacking laboratory results and treatment information, this study reflects well the outbreak patterns among children and adolescents with pneumonia. Our results provide a basis for future studies regarding ED treatment for children and adolescents with pneumonia.
