Objectives : The aim of this study was to investigate the sleep patterns of South Korean elementary school children and whether the differences in sleep patterns were related to behavior, emotional problems, attention and academic performance. Method : This study included a community sample of 268 boys and girls from fourth-, fifth- and sixth-grade classes in a South Korean metropolitan city from November to December 2010. The primary caregivers completed a questionnaire that included information on demographic characteristics, as well as the Child’s Sleep Habit Questionnaire (CSHQ), the Korean version of Child Behavior Checklist (K-CBCL), the Korean version of the Learning Disability Evaluation Scale (K-LDES), the Korean version of ADHD Rating Scale (K-ARS) and the Disruptive Behavior Disorder Scale (DBDS). We conducted analyses on the CSHQ individual items, between the subscales, on the total scores and on the K-CBCL, the K-LEDS, the K-ARS and the DBDS. Results : Based on the findings from the CHSQ, the subjects had significantly higher scores for bedtime resistance (9.18±2.17), delayed sleep onset (1.32±0.62), the sleep duration (4.19±1.52) and daytime sleepiness (14.10±3.55) than the scores from the previous reports on children from western countries. The total CHSQ score showed positive correlations to all subscales of the K-CBCL : withdrawn (r=0.24, p<.005), somatic complaint (r=0.24, p<.005) and anxious/depressive (r=0.38, p<.005). Bedtime resistance was associated with oppositional defiant disorder (r=0.15, p<.05) and a positive correlation was demonstrated between sleep anxiety and the oppositional defiant disorder score (r=0.13, p<.05), night waking and the conduct disorder score (r=0.16, p<.05). Delayed sleep onset was related with low performance on the K-LDES with respect to thinking (r=-0.17, p<.05) and mathematical calculation (r=-0.17, p<.05). Conclusion : The results of this study reconfirm Korean children’s problematic sleep patterns. Taken together the results provide that the reduced sleep duration and disruption of sleep pattern can have a significant impact on emotion, behavior, performance of learning in children. Further studies concerning more diverse psychosocial factors affecting sleep pattern will be helpful to understanding of the sleep health in Korean children.

37세 폐결핵 남자환자와 동종신장이식 후 steroid 치료받은 48세 남자환자의 설사변에서 C. lari를, 위암으로 항암 치료를 받은 64세 여자환자의 설사변에서 C.hyointestinalis를 분리하였다. 이세균은 모두 Campylobacter의 선택배지인 Butzler 배지에서 분리되었다. Campylobacter 장염의 상대적 빈도가 증가하고 있으며, 대부분의 원인균은 C. jejuni subsp. ujejni와 C. coli이지만, 드물게는 C. lari와 C. hyointestinalis도 일으킬 수 있다는 결론을 얻었다. Compylobacter lari and C. hyointestinalis were rarely isolated from the patients with diarrhea. We isolated C. lori from the stool culture of a 37-year-old man with pulmonary tuberculosis and a 48-year-old man with kidney transplantation, and C. hyoinlestinalis from the stool culture of a 64-year-old woman with gastric cancer. These organisms were isolated on Butzler media, and identified by biochemical characteristics and antimicrobial susceptibility to nalidixic acid and cephalothin. This report suggests that the clinical significance of Campylobacter species must be expanded to include C. lari and C. hyointestinalis as a potential cause of human gastrointestinal disease.
