The purpose of this study is concerned with an investigation of the actual condition of traumatic injuries of teeth and supporting structures in children to set up possible criteria for prevention and treatment of injured teeth. The materials consisted of the clinical records of 431 traumatically injured teeth of 212 children, accumulated during two years from the first of April in 1998 to the end of March in 2000, supplied from the Dept. of Pediatric Dentistry, Chonbuk National University Hospital. The incidence of injuries in boys was extremely high for permanent teeth, twice as high as in girls. Accidents to primary teeth were most common from 1 to 2 years of age and to permanent teeth were most from 8 to 9 years of age. The most common cause of trauma was a fall for both primary and permanent teeth, followed by collision. The anterior teeth in maxilla was most frequently affected by trauma in both the primary and permanent teeth. The most common type of trauma were loosening for the primary teeth, followed by luxation types which included the intrusion, displacement and extrusion and complete avulsion types. For the permanent teeth, the most common type of trauma were tooth fracture. The most common trauma of soft tissue was laceration of upper lip, lower lip and gingiva of maxilla Concerning treatment at the first visit, primary teeth with only loosening and concussion were not usually treated. Permanent teeth were often treated by crown restorations for crown fractures and by endodontic procedures for pulpal exposure. Though we could elucidate actual condition of traumatic injuries of teeth in children, we should make a follow-up survey to ensure the prognosis of injured teeth and establish the most desirable criteria for traumatized teeth in children.

This study purpose was to explore whether career maturity and parents-children relationship related factors were differentiated by giftedness, gender and secondary school level (research question 1). In addition, this study focused on the effects of parents-children relationship related factors on career maturity with a comparison on gifted and regular students (research question 2). The sample included 213 gifted middle school and high school students who participated in the Korean gifted education center and 243 regular students. Multivariate analysis of variance was conducted for research question 1, and hierarchical regression analysis was conducted for research question 2. The results of this study showed that (1) gifted students showed a higher level of career maturity, achievement expectation (parents-children relationship), respect (parents-children relationship), discussion and leisure (activity with parents), sharing ordinary life and communication (activity with parents), career support of parents compared to regular students ; (2) Girls showed higher level only in sharing ordinary life and communication compared to boys ; (3) middle school students more highly perceived the parents' achievement expectation and control, respect for parents, activities with parents (discussion and leisure, sharing ordinary life and communication) compared to high school students ; (4) the career support of parents was the strongest predictor of career maturity, and discussion and leisure was also a significant factor predictor of career maturity. Based on these results, it was suggested for parents to support their children's career maturity of both gifted and regular students by increasing frequencies of various activities shared with their children such as discussion and leasure.

The Purpose of this study is to provide the basic data for the improvement or the contents or clothing curriculum in the 7th technology home economics of middle school. The standard of satisfaction of students' according to the detail domains and the standard of necessity and practical use and learners' patterns of activity task suggested in textbooks were evaluated. The ninth grade 169 boy students and 336 girl students in the national capital region were participated in this survey. According to the survey results, firstly, a dress domain got the highest relative importance(28.56%) while a clothes material domain took the lowest relative importance(8.07%) among various detail domains. Secondly, the standard of satisfaction according to each detail domain fell below the average. Generally girls' satisfaction for teaching was higher than boys'. Thirdly, a clothes material domain showed the lowest necessity for textbook contents according to detail domain and other domains showed above the average. The necessity for textbook contents appeared high for boy students rather than girl students. In addition, boy and girl students did not have interest in content relevance in textbook. Especially, they could not do well and understand experiments and practices in clothing section. Finally, The degree of utilization of the activity task ill textbooks was very low. Among various activity tasks, the learning by discovering and exploring were more utilized than cooperating learning.

The purpose of this research was to provide the information needed for improving the contents in housing unit of middle school technology and home economic textbook. For this purpose, a survey questionnaire was developed to examine teachers' importance perception of 48 contents in housing unit. A direct survey and an e-mail survey were used to collect data from teachers, and a total number of 233 data were analyzed. Conclusions were summarized as following: 1. Among the 48 contents in housing unit, the average score of teachers' importance perception of the 18 contents on 'interior environment and equipments' was 3.94; the average score of teachers' importance perception of the 15 contents on 'living space plan and use' was 3.78; and the average score of teachers'importance perception of the 15 content on 'housing maintenance and repair' was 3.42. Therefore, the 15 contents on 'housing maintenance and repair' must be revised. 2. Teachers' importance perception of 25 contents, among the 48 contents in housing unit, were significantly differentiated by gender, age, teaching experience, scholastic attainment, subject in charge(technology, home economics, technology and home economics), school type(boys' middle school, girls' middle school, coeducation), and region(city, county). Therefore, the 25 contents, of which importance perception were influenced by teachers' characteristics, must be revised in order to maintain the consistent importance perception. Suggestions were that the team teaching of technology and home economic textbook was more recommendable; that the local situations must be considered in the contents of housing unit and; that the contents of housing unit must be segmented into a minimum unit for the accurate evaluation.

The purpose of this study was to investigate food involvement, dietary behavior and relationship according to the levels of nutrition knowledge. Data in this research was obtained by using the questionnaire which was given out to 528 subjects(boys 182, girls 346) in Naju city area. The awareness of dietary behavior of middle school students put the first priority on breakfast from among 3 meals a day, and they selected 'taste' as the most important criterion. The majority and above of subjects responded that they had ever delivered food at least more than 1 or 2 times a week. This research found that middle school students are tends to regard themselves as being rather close to obesity or fatness. Subjects were also aware that they have some problems with a unbalanced eating habbit and irregular timing of having meals, and more than 40% of the subjects responded that they obtain the most of information about food & dietary behavior through television. Significant difference was found in the food involvement with related variables such as sex, grade, the academic background of mother, self-perception of weight, the way of weight control, perception of problems requiring improvement. Dietary behavior related with variables showed significant difference. Variables are grade, perception of meal importance, selecting standard of food, method of weight control, improvement of eating habits. Dietary behavior is found highly relative with food involvement. Dietary behavior is found highly relative with food involvement. In conclusion, suggestions that could bring motivation to improvement is more essential to the nutrition education rather than knowledge oriented education.

Purpose: To identify factors that influence serum zinc concentrations in children with acute gastroenteritis. Methods: Thirty-two children under 5 years of age (15 boys and 17 girls) were selected randomly among those who visited to an pediatric emergency room of Ehwa Womans University Mokdong Hospital with acute gastroenteritis from May to August 2005. This study estimated the association between serum zinc concentrations and clinical, biochemical variables in patients with acute gastroenteritis. Results: Serum zinc concentration was lower in febrile patients than afebrile patients with acute gastroenteritis ($67.5{\pm}25.3$ vs $85.5{\pm}14.2$, p<0.05). It also was lower in patients with positive C-reactive protein (CRP) than those with negative CRP ($63.9{\pm}25.4$vs $86.7{\pm}13.8$, p<0.05). Serum zinc concentration was negatively correlated (r=-0.494, p<0.05) with CRP concentration, whereas positively correlated with hematocrit (r=0.370, p<0.05), total protein (r=0.474, p<0.05), and albumin (r=0.636, p<0.05). Twelve patients (37.5%) showed very low serum zinc concentration (< $70{\mu}g/dL$) without clinical symptoms of deficiency or growth retardation. Frequency of febrile illness or positive CRP is significantly greater in group with zinc < $70{\mu}g/dL$ than the group with zinc ${\geq}70{\mu}g/dL$ (91.7% vs 55%, p<0.05; 91.7% vs 40%, p<0.05, respectively). Conclusion: In patients with acute gastroenteritis, serum zinc concentration was influenced by various factors such as fever, CRP, and biochemical factors. For evaluating zinc status in the body. factors.

Purpose : Conservative management of multicystic dysplastic kidney(MCDK) without nephrectomy has recently been advocated. The purpose of this study was to determine the clinical course of conservatively managed MCDK and to find out possible predictive factors for involution of MCDK by ultrasonography(US). Methods : A retrospective analysis was made on 45 patients(26 boys and 20 girls) in whom MCDK was detected and had been traced by US between Dec. 1993 and Aug. 2005 at Severance Hospital. Results : Median follow-up time was 30 months(range 2-102 months). All patients under-went radionuclide scans and voiding eystourethrograms. The serial follow-up US showed complete involution in 11(24%), partial involution in 19(41%), and no interval change or increased in cyst size in 13(28%) patients. Nephrectomy was done in 3 patients(7%) due to relapsing urinary tract infection(UTI) and severe abdominal distension. The mean age of complete involution of MCDK was 37 months(range 12-84 months). Episodes of UTI were present in 17 patients(37%) and additional genitourinary(GU) abnormalities were found in 22 patients(44%). Hypertension and renal insufficiency was complicated in one patient. No child developed malignant tumor. Univariate analysis showed that five variables were associated with complete involution of the MCDK; gender, site, UTI episode, additional GU abnormalities, and renal length on initial US. After adjusting using the Pearson model, the presence of additional GU abnormalities was exclusively associated with complete involution among the 5 variables(P=0.034). Conclusion : In our review of 46 cases of MCDK, non-surgical approach for patients with MCDK was advisable and we could predict poor prognosis when MCDK is associated with other GU anomalies.

Purpose: To investigate the effect of eating behavior on nutritional status according to temperament type. Methods: One thousand one hundred three preschool children aged 2 to 6 years in Gyeongsan, Gyeongsangbuk-do from April to June 2018 were surveyed about their eating behavior and nutritional status using DBT (Dietary Behavior Test) and NQ (Nutrition Quotient) which are proven tests. The dietary behaviors of the children were classified into four categories: approach avoidance, sensory sensitivity, hyperactivity, and irregularity. NQ scores were divided into five categories: balance, diversity, moderation, regularity, and practice. Results: The mean of the children's age was 3.42 ± 1.4 (596 boys and 507 girls). The percentage distribution of the NQ grade was as follows: 5.5% (highest), 12.5% (high), 47.1% (medium), 22.2% (low), and 12.6% (lowest). The risk group of approach avoidance and sensory sensitivity had significantly (p < 0.001) lower scores than the normal group in balance factor (51.9 ± 12.0 vs. 57.8 ± 15.9 in approach avoidance type, 52.6 ± 17.6 vs. 57.7 ± 15.9 in sensory sensitivity type) and diversity factor (32.5 ± 24.4 vs. 50.1 ± 22.4 in approach avoidance type, and 32.5 ± 24.0 vs. 50.7 ± 22.2 in sensory sensitivity type). The scores of the hyperactivity risk group were significantly lower in moderation factor (78.2 ± 12.1 vs. 81.2 ± 11.9), and those of the irregular risk group were significantly lower in variety (35.9 ± 24.5 vs. 48.8 ± 23.2), regularity (57.6 ± 37.1 vs. 66.1 ± 17.6), and practice (57.1 ± 19.4 vs. 65.1 ± 22.5) factors than the normal group (p < 0.001). Especially, the risk group of approach avoidance and sensitivity type had significantly (p < 0.001) lower intakes of whole grain, fruit, bean and bean products, vegetables, and Kimchi. Conclusion: This present study suggested that the eating behavior based on temperament of demanding preschool children affected food choice resulting in food consumption diversity of children. Therefore, it is important to provide customized nutrition education programs based on temperament type.

Dietary supplement use is prevalent and represents an important source of nutrition. This study was conducted in order to assess the dietary maximum exposure of vitamins and minerals from various sources including regular diet, vitamin mineral supplements for non-prescription drug (VMS-NPD), vitamin mineral supplements for health functional foods (VMS-HFF), and fortified foods (FF). A total of 1,407 adolescent boys and girls attending middle or high schools were chosen from various cities and rural communities in Korea. Users of vitamin and mineral supplements (n = 60, 15-18 years of age) were chosen from the above 1,407 students. Intake of vitamins and minerals from a regular diet and FF was assessed by both food record method and direct interview for three days of two weekdays and one weekend, and those from VMS-NPD and VMS-HFF were assessed by both questionnaire and direct interview, and compared with the recommended nutrient intake (RNI) and the tolerable upper intake level (UL) for Korean adolescents. Daily average exposure range of vitamins and minerals from a regular diet was 0.3 to 4.4 times of the RNI. Some subjects had an excessive exposure to the UL in the following areas: from regular diets, vitamin A (1.7%) and niacin (5.0%); from only VMS-NPD, vitamin C (9.1%) and iron (5.6%); and from only VMS-HFF, niacin (8.6%) > vitamin $B_6$ (7.5%) > folic acid (2.9%) > vitamin C (2.3%). Nutrients of daily total intake from regular diet, VMS-NPD, VMS-HFF, and FF higher than the UL included nicotinic acid for 33.3% of subjects, and, then, in order, vitamin C (26.6%) > vitamin A (13.3%), iron (13.3%) > zinc (11.7%) > calcium (5.0%) > vitamin E (1.7%), vitamin $B_6$ (1.7%). Thus, findings of this study showed that subjects may potentially be at risk due to overuse of supplements, even though most of them took enough vitamins and minerals from their regular diet. Therefore, we should encourage adolescents to have sound health care habits through systematic and educational aspects.

The purpose of this study was to verify the clinical utility of th Korea Child Behavior Checklist 16-18(K-CBCL 6-18) in diagnosing ADHD among children with psychological disorders in child welfare institutions. The participants were 509 elementary school children(309 boys and 200 girls) who lived in child welfare institutions. They were assessed using the Korean ADHD Rating Scale(K-ARS) and K-CBCL 6-18. Only five scales of the K-CBCL 6-18 related with attention were used for analysis: syndrom total, externalizing total, aggressive behavior, attention problems and DSM-oriented ADHD scales. The results were as follows. First, K-ARS and K-CBCL 6-18 had significantly positive correlations with all five scales. Second, as a result of a t-test on the ADHD and the non-ADHD groups, which were divided using K-ARS, the mean scores of ADHD group were significantly higher than the non-ADHD group for all five scales of the K-CBCL 6-18. The hit rate of all five scales of the K-CBCL 6-18 was 60 to 70 percent. The syndrom total and externalizing total scales had high sensitivity, whereas the aggressive behavior, attention problems, and the DSM-oriented ADHD scales had high specificity. In addition, all scales had high positive predictive values. Third, as the result of a t-test on the ADHD group and the emotional disorder group, there were significant difference in the mean scores of the attention problems and the DSM-oriented ADHD scales. The attention problems and the DSM-oriented ADHD scales had a similar percentage of hit rate, high specificity and low sensitivity. Especially, the DSM-oriented ADHD scale revealed higher specificity than the attention problems scale. The results of this study suggested that the five scales related to attention of the K-CBCL 6-18 are useful in diagnosing ADHD in child welfare institutions.
