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.

The purpose of this study was to verify preschool children can be classified of Attention-Deficit Hyperactivity Disorder (ADHD) children across situation. It also was to examine differences among groups according to sex and age, and to investigate the family caracterisitcs of ADHD groups. The subjects of this study consisted of 228 preschool chilren (147 boys and 136 girls aged from 3- to 7- year-old) drawn from five Child Care Centers in Chung-Ju. Data were analyzed by the frequency, percentages, Cronbach's ${\alpha}$ coefficient, ${\chi}^2$-test, F-test, Tukey post-hoc test, and Pearson correlation using SAS program. The results were as follows: 1. Preschool children could be classified by four diagnostic groups across situation; (1) 168 children (59%) of the control group (no disorder of ADHD), (2) 49 children (17%) of ADHD-Home group (ADHD only at home), (3) 43 children (15%) of ADHD-School group (ADHD only at school), and (4) 23 children (8%) of ADHD-PH group (ADHD both at home and at school). Ratings by parents and by teachers correlated very low with each other, as in previous studies. These results confirm the findings that ADHD be classified across situation. 2. There were significant differences among four groups according to sex and age. In the ADHD-PH groups, the boys is 3 times higher than the girls and the children aged 6- to 7-year-old was shown highly distributed in the pervasive ADHD.

Background: Snoring in children, is associated Kith adenotonsillar hypertrophy and sinusitis which contribute to upper airway obstruction, so we studied the sinusitis and adenoid size of snoring children with plain radiography Materials and method: Fifty patients having snoring, nasal obstruction in our hospital between November 2001 and November 2002 were studied using plain radiology PNS(water's view) and Neck lateral view(adenoid size with A/N ratio) Results: 1. In oriental medicine, Hu-Bi means laryngopharyngeal edema and obstruction, laryngopharyngeal disease are due to Hwa-Yeoul( fire and hot), sinus disease are due to Fung-Han(wind and cold) and Fung-Yeoul(wind and hot). 2. Age ranged from 2 to 17 year-old ( mean age: 6 years), 5-7 year-old were 18 patients (36%). Age of on set, 25 patients were 1-4 year-old (50%). 3. Of the 50 snoring patients, 37 patients were sinusitis(74%), 20 patients had enlarged adenoid(40%). Of the 20 large adenoid patients, 19 patients were sinusitis(95%). 4. Of the 50 snoring patients, size of tonsil were flowed. Fifteen were severe(3+), 17 patients were moderate(2+) and 15 patients were mild(1+). Of the 20 enlarged adenoid patients, size of tonsil flowed. Five were severe(3+), 11 patients were moderate(2+) and 4 patients were mild(1+). Conclusion : Of the 50 Snoring patients, 37 patients showed sinusitis(74%), 32 patients showed large tonsil(64%), 20 patients showed large adenoid(40%).

This study examined the development of phonological awareness of 3-, 5-, and 7-year-old children, 20 subjects at each age level. The 3-year-olds were given 2 phoneme detection tasks and the 5- and 7-year-olds were given 5 phoneme detection tasks. In each task, the children first heard a target syllable together with 2 other syllables and were asked to tell which of the 2 syllables sounded similar to the target. Children were able to detect relatively large segments ($Consonant_1+Vowel$ or $Vowel+Consonant_2$: $C_1V$ or $VC_2$) at the age of 3 and gradually progressed to smaller sound segments(e.g., phonemes). This study indicated the Korean children detect $C_1V$ segments better than $VC_2$ segments and detect the initial consonant better than the middle vowel and the final consonant.

The purpose of this study was to investigate children's ideas about self-regulation in such situational variables as the presence of explicit rules and the domains of social rules. The subjects were 6-, 9-, and 12-year-old children (344). To assess children's ideas about self-regulation, a procedure was devised in which children were presented with stories portraying a protagonist in a conflict between an implicit or an explicit rule and a personal desire. The children were asked to make a choice for the protagonist and to give reasons for their choice. Major findings as follows: (1) There was significant difference in children's self-regulation depending on the presence of explicit rules. (2) There was significant difference in children's self-regulation depending on the domains of social rules. In situations that involved no explicit rules for behaviors, there were significant differences depending on the domains. In situations that involved explicit rules for behaviors, for 6- and 9-year-old children, there was no significant difference depending on the domains. (3) Children's use of justifications for their choice of action varied as a function of the characteristics of the social rules.

This study investigated preschoolers' happiness, behavior problems, and interpersonal problem solving strategies according to their sex and age, and the relationships among them. The subjects were 185 preschoolers (97 boys and 88 girls; 83 four-year-olds and 102 five-year-olds). Results showed that boys were higher in behavior problems (aggression) and forceful problem solving strategies than girls, while girls were higher in happiness (characteristics of self) than boys. Also, 4-year-old children were higher in forceful problem solving strategies than 5-year-olds. Children's happiness was negatively related to their internalizing and externalizing behavior problems. Behavior problems and interpersonal problem solving strategies of children were influenced by their happiness. These findings provide preliminary evidence that children's happiness may predict their behavior problems and interpersonal problem solving strategies.

Objective: The purpose of this research was to investigate the age-related changes in whole-body motor variability during sit-to-stand (STS) task. It has been reported that children perform motor tasks less accurately with greater variability as compared to adults. However, it is still unknown how they utilize the abundant degrees of freedom and accomplish voluntary actions. Uncontrolled manifold (UCM) analysis has been used to partition motor variabilities into two independent variability components, task-relevant variability (V_ORT) and task-irrelevant variability (V_UCM). We investigated what differences exist between children and adults with respect to these two motor variability components in relation to motor development stages. Method: Ten 6-year-old children (height: 116.2 ± 4.3 cm, weight: 23.1 ± 3.9 kg, motor development assessment percentile score: 77.5 ± 18.6%), ten 10-year-old children (height: 138.7 ± 7.2 cm, weight: 35.8 ± 10.3 kg, motor development assessment percentile score: 73.9 ± 12.7%), and ten young adults (age: 23 ± 1.6 year-old, height: 164.3 ± 11.4 cm, weight: 60.8 ± 12.0 kg) participated in this study. Each participant performed STS ten times, and a motion capture system was used to capture the whole-body kinematics. Each segment centers of mass and the whole-body center of mass were calculated, and UCM analysis was used to quantify motor variabilities, V_ORT and V_UCM. One-way ANOVA was used for statistical analysis. Results: We found that children produced more motor variabilities in V_ORT and V_UCM in all three dimensions, anterior-posterior, medial-lateral, and vertical. As age increased, both, V_ORT and V_UCM significantly decreased (p<.05). Conclusion: The greater V_ORT found in children compared to adults indicates that the repeatability over repetitions improves through development, while the greater V_UCM found in children suggests that children better utilize the abundant degrees of freedom during STS compared to adults.

Respiratory tract symptoms such as cough, wheeze, and strider may occur frequently or persist for long periods in a substantial number of children, others may have persistent or recurring lung infiltrates with or without symptoms. It is important to study on clinical significance of this symptoms for avoiding unnecessary test or treatment. Chronic or Recurrent Respiratory Symptoms are similar to cold(感冒) and cough(咳嗽) in Oriental Medicine. Diagnostic criteria is followed : in case of children less than three years old, upper respiratory infections are more than seven per year or lower respiratory infections are more than three ; in case of children three to five years old, upper respiratory infections are more than six per year or lower respiratory infections are more than two ; in case of children six to twelve years old, upper respiratory infections are more than five per year or lower respiratory infections are more than two. In oriental medical treatment is classified into the treatment of internal use, external use, internal and external use, acupuncture, cupping therapy, and combination treatment of chinese and western medicine.

The purpose of this study was to examine the development of detailed description for drawing houses according to the shapes of lines, and dimensions of space from 4 to 5 years-old children. Participants were 76 children from a daycare center in Busan, Korea. Each child was asked to draw 4 different houses according to the shapes of lines and dimensions of space, such as: straight lines and 2-dimensional pictures straight lines and 3-dimensional Models, curved lines and 2-dimensional pictures and curved lines and 3-dimensional models. The children's drawings were scored based on a "detailed description rating table" which consisted of 10 items. Summarizing the overall results, first, 5 year-olds scored significantly higher than 4 year-olds in the detailed description of 4 different house models. Second, the houses with straight lines scored significantly higher than those with curved lines in the detailed description. Third, there were no significant differences between 2-dimensional houses and those of 3-dimensional models in the detailed description. These results suggest that the detailed description of young children's drawing is developed as children grow older, and drawing with straight lines are earlier developed than curved lined drawings.
