The purpose of this study was to develop effective oral health education programs for mentally retarded children and promote their oral health, by offering oral health education for 45 mentally retarded children between age 6 to 20, tracking the change of their knowledge depending on the frequency of education, and examining the educational effect before and after oral health education. The children with mental retardation attended a special school for idiots in Gweonseon-gu, Suwon, Kyonggi Province, being able to take training(IQ 25-49). The education program was designed to be suitable for their cognitive power after consultation with a special school teacher. A teacher provided the same education seven times, once a week, and an interview was held with each of them to assess their correct answer rate. The findings of this study were as below: 1. The repeated oral health education served to have the children with mental retardation acquire better knowledge about harmful food for the teeth, what had to be done after eating cookies or candies between meals, the right time for toothbrushing, the concept of dental caries, and how to cope with dental caries(p<0.01). But after that education was offered four times, the frequency of that education made no difference. 2. The repeated oral health education increased, their knowledge on the role of the teeth and the right choice of toothbrush(p<0.01), yet there was no significant difference in their knowledge about oral health behavior, because they had already been familiar with that. 3. As a result of investigating the change of their oral health know-ledge before and after oral health education according to the type of handicap, the type of handicap made no significant difference to the change of their oral health knowledge. 4. The oral health education for the children with menial retardation had a significantly different effect on their knowledge about harmful food for the teeth, what had to be done after eating between meals, the right time for toothbrushing, the role of the teeth. the right choice and use of toothbrush, how to do toothbrushing, and fluorine(p<0.01).

The objectives of this study were to analyze and compare 24 hrs personal exposure levels of MF at microenvironments such as home, school, educational institute, internet pc game room, transportation, and other places according to time activity patterns using various metrics for children attending the primary schools located near and away from the power lines, and to characterize the major microenvironments and impact factors attributed personal exposure level. The study was carried out for 44 children attending a primary school away from the lines(school A) and 125 children attending a school away from 154 kV power lines(school B), all who aged 12 years and were 6 grade, from July 2003 to December 2003. All participants filled in a questionnaire about characteristics, residence, use of electrical appliances and others. Children wore a small satchel in which EMDEX II and Lite (Enertech, Co. Ltd) and a diary of activity list for period of registration in 20 minutes blocks. All statistical calculations were made with the SAS System, Releas 6.12. The summary of results was presented below. First, about the characteristics of subjects, there no differences between two groups. The subject almost spent about 56 % of their time at home and about 20~25 % of their time at school. Fifty percent of children spent 2 hours at private educational institutes. Second, the personal exposure measurements of children in school B was statistically higher than those of children in school A by various metrics such as arithmetic mean, geometric mean, percentile(5, 25, 50, 75, 95), maximum, rate of change metric, constant field metric. The arithmetic and geometric mean magnetic fields during the time the children were at school B were 0.98 and $0.86{\mu}T$ and were about 23 times higher than those of children were at school A. In conclusion, the significant major determinants of personal exposure level is the distance from the power line to microenvironments.

Although the improvements in the health sanitary facilities of the elementary school were made by the implementation of the 7th curriculum, color design and concept of toilets used by lower classes students were shown to be still insufficient and so, it is also necessary to have color planning for toilets considering users' preferences. This study is targeting lower classes children of elementary schools under Seoul Gangseo Office of Education. The purpose of this study is to propose a toilet color design direction preferred by children as users. Therefore, the toilets of elementary school were investigated and at the same time, juvenile pictures were analyzed. The results of this study are that the color space used in the current design, the following gives a substantial psychological and emotional impact for many elementary school children in the developmental stages of children leads to an interesting use of color. Therefore, this study propose to improve the toilet to a more familiar environment with high accessibility considering the development of the child when using color in design space through color preference.

Purpose: The use of implantable cardioverter defibrillators (ICDs) to prevent sudden cardiac death is increasing in children and adolescents. This study investigated the use of ICDs in children with congenital heart disease. Methods: This retrospective study was conducted on the clinical characteristics and effectiveness of ICD implantation at the department of pediatrics of a single tertiary center between 2007 and 2011. Results: Fifteen patients underwent ICD implantation. Their mean age at the time of implantation was $14.5{\pm}5.4$ years (range, 2 to 22 years). The follow-up duration was $28.9{\pm}20.4$ months. The cause of ICD implantation was cardiac arrest in 7, sustained ventricular tachycardia in 6, and syncope in 2 patients. The underlying disorders were as follows: ionic channelopathy in 6 patients (long QT type 3 in 4, catecholaminergic polymorphic ventricular tachycardia [CPVT] in 1, and J wave syndrome in 1), cardiomyopathy in 5 patients, and postoperative congenital heart disease in 4 patients. ICD coils were implanted in the pericardial space in 2 children (ages 2 and 6 years). Five patients received appropriate ICD shock therapy, and 2 patients received inappropriate shocks due to supraventricular tachycardia. During follow-up, 2 patients required lead dysfunction-related revision. One patient with CPVT suffered from an ICD storm that was resolved using sympathetic denervation surgery. Conclusion: The overall ICD outcome was acceptable in most pediatric patients. Early diagnosis and timely ICD implantation are recommended for preventing sudden death in high-risk children and patients with congenital heart disease.

This study analyzed the relation of children's attachment security and mother-child interaction to children's peer interactions. The subjects were 51 preschoolers, 44 to 57 months of age and their mothers. Attachment was assessed using the Attachment Q-set (Waters, 1987), mother-child interactions at home were observed with the use of the Teaching Strategies Rating Scales (Erickson, Sroufe, Egeland, 1985), and peer interactions were observed during free play time, using the Holloway and Erickson(1988) categories. Pearson correlation and multiple regression showed that attachment security scores were negatively related to dependency toward peers. Mother's "structure and limit setting" and "respect for child's autonomy" were positively related to "helping with peers" and negatively to "asking for help" and "physical attack". The variables accounting for dependency toward peers were mother's hostility and attachment security.

This study investigated children's interests in learning English, affected by educational activities in and out of institutes, and mothers' perceptions regarding early childhood English education. We recruited, 253 mothers of 3- to 5-year-old children in either general kindergartens or English immersion institutes. They answered questions on socioeconomic status, perceived interest in English by their children, their perceptions regarding early childhood English education, and English education outside institutes. In addition, 42 English teachers provided information within institutes such as class time per week, teacher-pupil rate, and language use policy during class. The collected data were analyzed through SPSS 22 for frequency analysis, descriptive statistics, independent t-test, and hierarchical multiple regression analysis. The major findings are as follows. First, the two groups were in distinct learning environment. Second, mothers' perceptions and outside-institute activities were significantly different between the two groups. Third, the English interests of children at both institutes were influenced by mothers' worries and at-home English interactions. Fourth, education within institutes did not affect both group's English interests. Fifth, private education and socioeconomic status did not affect both group's English interests. Lastly, only the children's interests in English immersion institutes were affected by gender and mother's perceived necessities. Focusing children's interests, this study helps in understanding young children's affective aspects regarding learning English. The findings are expected to be a guideline for each home and institute to increase children's interest in learning English.

Bed rest is recommended to prevent postlumbar puncture headaches(PLPHA), but the period of bed rest varies in the literature from 6 hours to 24 hours. In clinical practice the period of bed rest varies but nursing methods for adults and children have little difference. In Seoul National University Hospital, children have been given at least 6 hours bed rest after a lumbar puncture. Pediatric oncology patients require a lumbar puncture for an initial diagnosis, follow up treatment or administration of chemotherapeutic agent. But it is difficult for young children to lie supine or to refrain from their usual activities in any way, and unpleasant problems related to a shortage of beds often occurs during discharge or in an outpatient setting. The purpose of this study is to substantiate the preventive effect of PLPHA by the period of bed rest, to identify the other factors that influence PLPHA, and to use the nursing methods proper to children. The subjects were 65 children, ages 1-17, undergoing treatment in the children's cancer center at SNUCH during the period June 1, 1995, to Aug. 31, 1995. The team nurses asked questions about PLPHA of the parents and children in order to fill out a questionnaire. The data were evaluated by percent, t-test, Chi-square test and Mann-Whitney U test. Result; 1. There was no significant difference relating the bed rest time spent to the occurrence of postspinal headaches (t-test). 2. There was a significant risk of PLPHA in the children who were irritable before procedure and/or had experienced previous PLPHA(p<0.05, ${x^2}-test$). 3. The following factors were not found to be associated with increased risk of PLPHA: previous puncture experience, giving analgesics, the choice of puncturist, inpatient/outpatient status, gauge of needle, purpose, the amount of CSF removed, gender, diagnosis, the number of peripheral WBCs, previous lumbago experience after LP, position after bed rest, age, the number of aural puncture at the time. A longer period of bed rest is unlikely to be more effective to prevent PLPHA and seems impractical. A shorter period will save time and effort. Perhaps it will also allay some of the fears which surround LP. So 1 hour bed rest after LP is suggested and nursing methods for emotional support should be investigated to reduce PLPH.

Purpose: Congenital diaphragmatic hernia (CDH) is rare but potentially fatal. The overall outcome is highly variable. This study aimed to identify a simple and dynamic parameter that helps predict the mortality of CDH patients in real time, without invasive tests. Methods: We conducted a retrospective chart review of 59 CDH cases. Maternal and fetal information included the gestational age at diagnosis, site of defect, presence of liver herniation, and lung-to-head ratio (LHR) at 20 to 29 weeks of gestational age. Information regarding postnatal treatment, including the number of days until surgery, the need for inhaled nitric oxide (iNO), the need for extracorporeal membrane oxygenation (ECMO), and survival, was collected. The highest respiratory severity score (RSS) within 24 hours after birth was also calculated. Results: Statistical analysis showed that a younger gestational age at the initial diagnosis (P<0.001), a lower LHR (P=0.001), and the presence of liver herniation (P=0.003) were prenatal risk factors for CDH mortality. The RSS and use of iNO and ECMO were significant factors affecting survival. In the multivariate analysis, the only remaining significant risk factor was the highest preoperative RSS within 24 hours after birth (P=0.002). The area under the receiver operating characteristic curve was 0.9375, with a sensitivity of 91.67% and specificity of 83.87% at the RSS cut-off value of 5.2. The positive and negative predictive values were 82.14% and 92.86%, respectively. Conclusion: Using the RSS as a prognostic predictor with simple calculations will help clinicians plan CDH management.
