Objectives : The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.

본 연구는 수직적 골결손부에 골이식을 시행한 후 교정력 적용시기에 따른 치주조직의 반응을 알아보고자 시행하였다. 체중 15 kg 내외의 성견 9마리에서 상악 좌우측 제3절치의 원심 치근면에 수직적 골결손을 형성하고 치주질환을 유발시킨2주 후 치주판막술을 시행하고 골결손 기저부 수준의 치근면에 기준 흠을 형성하였다. 골이식 후 치유기간에 따라 2주군, 4주군, 6주군으로 각각 3마리씩 분류하고 우측 제3절치는 치주판막술만 하는 비이식측으로, 좌측 제3절치는 치주판막술과 골이식을 병용한 이식측으로 설정하여 양측 모두 술후 2주, 4주, 또는 6주부터 120 gm의 교정력을 적용하여8주 동안 치체이동 시킨 후2주간 보정하였다. 이후 동물을 희생시키고 조직표본을 만든 후 치주조직의 반응을 비교 관찰하여 다음과 같은 결과를 얻었다. 1. 모든 실험동물에서 비이식측에 비해 이식측의 골재생양이 많이 나타났다. 2. 6주군에서는 홈에서 백악-법랑 경계부까지 거리의 1/2이상 치조골과 백악질이 재생되었고 상피의 하방증식없이 결합조직대가 치근면과 부착을 이루었다. 3. 4주군에서는6주군과 유사한 치주조직 재생소견을 보였으나 그 양은 더 적게 나타났다. 4. 2주군의 경우 골재생이 양측 모두 홈에 한정되어 나타났으며 상피의 하방증식이 홈의 기저부까지 연장되고 백악질과 결합조직의 재생은 관찰되지 않았다. 이상의 결과는 치주질환에 의한 수직적 골결손 환자에서 치주판막술과 골이식을 시행하고 교정적 치아이동을 할 경우 교정력 적용시기에 따른 치주조직의 반응이 차이가 있음을 시사하였다. (주요 단어 : 수직적 골결손, 골이식, 교정력 적용시기, 치주반응) The aim of this study was to investigate the periodontal response according to the timing of orthodntic force application after bone graft into the angular bony defect. Nine dogs were divided into three groups, 2, 4, and 6 weeks, according to the timing of orthodontic force application after bone graft. Periodontal angular bony defects were created surgically at the distal aspect of both maxillary third incisors. Two weeks later, flap operation was performed to eliminate inflammation and reference notch was made on the root surface at the level of the bottom of each defect. Demineralized freeze-dried bone was implanted on the left side whereas only debridement was done on the other side. Experimental tooth movement was executed during 8 weeks on both graft and non-graft sides. After 2 weeks of retention period, animals were sacrificed for histologic specimens. The results were obtained as follows : 1.New bone formation was more pronounced in the graft side than in the non-graft side in all experimental animals. 2.In the 6-week group, new bone and cementum formation was observed in more than half from the notch to the cemento-enamel junction, and the zone of connective tissue attachment was found without apical migration of junctional epithelium. 3.In the 4-week group, the amount of new bone formation was smaller than in the 6-week group whereas the overall remodeling pattern was similar. 4.New bone formation was confined to around the notch and the junctional epithelium migrated apically to the level of the notch with no connective tissue attachment and cementum formation in the 2-week group. The results of the present study suggest that periodontal response may be influenced by the timing of orthodontic force application after bone graft into angular bony defect.

This study is intended to verify an appropriateness of a test tool for elementary school students, which was made by Oh Suk-Yeong(1966) and modified by Jang Jeong-Ae (1998), in order to examine the test tool of the emotional intelligence for elementary school students, as a part of providing the basic data for a development of a new test tool. The survey was conducted for 250 students in the fifth grade and 150 students in the sixth grade, except dishonestly-responded 12 students among total 412 students of 'P' and 'S' Elementary School located in Dalseo-gu, Daegu. The following is the result of looking into a reliance of the Emotional Intelligence test through statistics of the emotional intelligence test. Firstly, the overall average answer rates were similar. However, there was a high variation of a minimum value and maximum value. Secondly, students in the fifth grade had higher score of the emotional intelligence than students in the sixth grade for all areas except the emotional control, as the result of examining the difference o the emotional intelligence score by grades. In terms of the difference of the emotional intelligence score by gender, female students had higher average score than male students for all areas except a repletion. Thirdly, there was the different reliance on the test tool of the emotional intelligence between male and female students. However, the overall reliance by grade was similar. Next, the survey indicated that there was a low relation in terms of a relationship between the whole and items. However, the appropriateness of individual item was low. Finally, there was the relatively low relation between sub-areas, as the result of looking into the appropriateness of the emotional intelligence test. However, it showed the relatively high relation between sub-area and the whole.
