홍강의,송혜양,김중술,홍경자,박성수 大韓神經精神醫學會 1988 신경정신의학 Vol.27 No.2

This is an epidemiological study of emotional/behavior problems in Korean elementary school children(total 2,399 : 1.236 boys, 1,163 girls) by empolying Children's Behavior Check List(CBCL) developed by Achenbach and Edelbrock(1983), to which 3 problem items were added for this study. A test-retest reliability of CBCL was was assessed by computing the Spearman-Browm correlation and the average correlation among items was. 72. The interparent agreeement was also assessed and the average correaltion between mother and father was. 62. The study subjects were drawm by stratified sampling from 5 schools in Korea ; 3 schools (A, B, C) from Seoul, one school(D) from a medium size city one school (E) from a rural town. School C is located in upper/middle-upper class residential area, School A and D in middle class, and School B and E in lower-middle/lower class. The present paper reports the prevalence of behavioral/emotional problems in relation to sex, grade, locality and socioeconomic variables. Some of the major findings were as follows ; 1) The mean total problem score excluding 3 additional items was 27.28 and did not differ significanthy according to sex and locality(Seoul vs non-Seoul), However, the mean total problem scores were significanthy different from school to school. The lowest score was observed in children of School C(22.15), higher scores for School B(30.89) and E(30.64) and in-between scores for the School A(27.58) and D(25.47). Father's education also had significant effect on the total problem scores : 31.46 for elementary of less 27.79 for middle and high school and 23.05 for college or more. As for to the grade, mean total score was lowest for the first graders(22.12), increasing up until 4th grade(29.83), then decreasing for 5th graders(26.81) and then relatively high score for the 6th graders(29.81). 2) Examination of each 122 problem items revealed that prevalence rate ranged from 2.1% to 61.7% : less than 5% for 13% items, 5-10% for 18 items, 10-20% for 31 items, 20-30% for 25 items, 30-40% for 15 items, 40-50% for 13 items, more than 50% for 7 items. Although sex did not make any difference in total problem scores, examination of the prevalence of each item revealed that 47 problem items were significanthy different between sexes : 26 items were more prevalent in boys and 21 items in girls. The items more prevalent for boys were externalizing problems such as hyperkinetic, aggressive and other behaviors and 21 items, more prevalent for girls were internalizing problems such as emotional and psychosomatic problems. School grade had significant effect in 47 items, only 3 of which showed lower prevalence in the younger children and the prevalence of 39 items were higher in older children. Significant differences were observed in 83 items, and 94 items, respectively according to school and father's education that could be considered to reflect socioeconomic status and it was reavealed that the lower the status, the higher the prevalence in most items. Items more common in upper class tend to be more anxiety-tension related(internalizing) and items more common in lower class tend to be more aggressive, hyperactive and other behavioval problems(externalizing). 3) Brief cross-cultural comparisons between the current study and other studies reported in the literature revealed major differences in several areas. The total problem score for Korean children was much higher than those of American and Dutch children, but lower than those of Canada and Chile. Although most of other studies reported higher total problem scores for boys, than for girls there was no sex difference in total problem score for Korean children. This was reflected in the finding of an almost equal numbers of items(26 for boys, 21 for girls) being more common than the other sex. Analyses by grade(age) also indicate major differences between Korean and American-Dutch children ; In contrast to the finding that total problem score was higher and larger number of items were more common for younger children in American and Dutch studies, they were higher for older children in Korean study. Socioeconomic variables seems to exert far more significant effect on the total score and the prevalence of each items in Korean study, when compared with American and Dutch studies. Further analyses of the data including a comparison with a clinic sample are deferred to another paper and so are the factor analysis results of 122 items into emotional/behavioral syndromes.

The intracavitary cones were designed which were made of stain-less steel and have scratched inside cone to be generated electron scatter and designed to be attached easily to the LINAC collimator and controlled cones length to be contacted smoothly between the patient and the cone tip. Two types of intracavitary cones were designed. One is the straight end cones with circular opening on the distal end and the other is 30 degree beveled end cones with elliptical opening on the distal end Each type of intracavitary cone ranged in daimeter from 2.5 cm to 3.5 cm and required a separate set of lower trimmer annulias cone diameter. The film phantom was designed with an internal cassette that accurately aligned the film edge with the film phantom surface. Film optical density data were measured by photodensitometer( Wellhofer 700i) Dosimetry measurements were made to commission the LINAC for 6 - 20 MeV electron using the intracavitary cones. Isodose curves were measured for all energy and cones combinations. Output is defined as the maximum dose per MU along the clinical central axis in water at 113 cm SSD. Calibration output, defined to be the output for the 15cm x 15cm diameter straight cone, was adjusted to 1.00 cGy/MU at each energy according to the TG-21 pro- tocol.

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.
