In order to analyze the sex-linked lethal mutagenic effects of ethyl methanesulfonate (EMS) in Drosophila melanogaster, the mutagenicities from the attached-X and Basc method have been detected. The indexes of relative lethal mutations at 2.0 and 4.0mM EMS treated group using the attached-X method were about 1.5 and 2.4 times than that of 1.0mM treated group, respectively. EMS had more pronounced effect in the sperm and spermatid stages in the induction of X-linked lethal mutations during the spermatogenesis. And, in the induction of X-linked recessive lethal mutations from the Basc method, the mutation frequency of 4.0mM EMS treated group as compared with 2.0mM was more than three fold. Two assay systems used in this study can support mutually according to experimental purposes, and the area of its application can be considerably wide.

Objective : This study aimed to investigate the associations of anxiety symptoms with behavior and attention in elementary school children with attention-deficit/hyperactivity disorder (ADHD). Methods : A total of 195 elementary school children with ADHD participated in the study. The Korean Version of ADHD Rating Scale (K-ARS) and Behavior Assessment System for Children(BASC-2) were used to measure the children's behavior. Anxiety and attention was assessed with State-Trait Anxiety Inventory for Children (STAIC) and ADHD Diagnostic System (ADS), respectively. Children with ADHD were categorized to two groups of ADHD with low anxiety (ADHD-LA) and ADHD with high anxiety (ADHD-HA) according to the total STAIC scores. Scores on K-ARS, BASC-2 and ADS were compared between two groups of ADHD-LA and ADHD-HA. Results : The Scores on K-ARS total and both subscales in ADHD-HA group were significantly higher than ADHD-LA group. Scores on the BASC-2 subscales including hyperactivity, aggression, conduct problem, anxiety, depression, somatization, withdrawal, attention problems were also significantly higher in ADHD-HA group compared to ADHD-LA group. In contrary, scores on ADS subscales were not significantly different between the both groups. Conclusion : Our study identified that the anxiety accompanied with ADHD was associated with the negative behavioral aspect in children with ADHD. However, the performances on attention task were not affected by the anxiety comorbid with ADHD. Future studies to reveal underlying mechanism are needed for further understanding the association with anxiety and ADHD.

Objectives ： The purpose of this study was to evaluate gender differences with respect to the internalization or externalization of symptoms according to the amount of time spent engaged in extracurricular education. Methods ： The study included a community sample of 755 boys and girls (mean age, 6.6 years), collected from five elementary schools in Gunpo, South Korea. Primary caregivers completed a questionnaire which included information on demographics, the amounts of time children spent in extracurricular education and with other activities, and an adapted form of the Behavior Assessment System for Children (BASC-2). Gender differences regarding externalizing and internalizing behavior problems were examined according to extracurricular education. Results ： With respect to the boys, there was a difference in the frequency of those who had externalizing behavior problems according to their time spent in extracurricular education. In contrast, the girls exhibited no difference. With respect to those children who spent a lot of time engaged in extracurricular education, there was a gender-specific difference only with respect to externalizing behavior problems. Conclusion ： A gender-specific difference exists only in terms of externalizing behavior problems according to time spent engaged in extracurricular education.

목적 연구의 목적은 빈곤가정아동의 문제행동과 비만도의 발생양상을 밝히고 그 관계를 규명하는 것이다. 방법 인천지역 22개의 지역아동센터의 차상위계층과 기초생활수급자 가정의 초등학교 4-6학년 아동 197명을 대상으로 신체검진과, 아동이 직접 아동문제행동검사(K-BASC2)를 수행하였으며, 자료분석은 SPSS17.0을 이용하여 빈도분석과, Mann-Whitney test, Kruskal-Wallis test를 실시하였다. 결과 신체계측결과 중등도이상비만이 9.6%이었다. 문제행동에서는 내면화문제의 위험군이상은 8.6%, 주의력결핍/과잉행동문제 위험군 이상은 22.8%, 학교문제의 위험군은 33.8%, 적응기술에서 49%가 위험군 이상이었다. 이는 2012년 교육과학기술부에서 우리나라 전국초등학생을 대상으로 실시한 정서행동선별검사보다 매우 높은 비율이었다. 성별에 따른 문제행동의 결과는 모든 영역에서 남학생에서 높은 비율이었다. 비만도에 따른 문제행동의 결과는 학교문제와 정서지표에서 비만도 그룹간 차이가 유의한 결과를 보였다. 결론 빈곤가정아동을 대상으로 현재의 학교 체계 안에서 이루어지는 검진시스템보다 더 자주, 주기적으로 점검되어야 하며, 특히 정신, 행동문제의 조기발견과 심각한 질환으로 발전하기 전에 아동 일대일 맞춤치료와 지속적인 상담, 간호중재가 절실히 필요하다. 특히 빈곤가정의 비만한 아동은 정신건강의 스트레스를 많이 받는 만큼, 이 아동들을 질병발생의 위험군으로 선정하고 조기발견, 예방중재, 치료적 상담의 시스템을 아동에게 적용해야 할 필요가 있다.
