Using a reliable assessment procedure and according to the severity of hyperactivity, thirty-six clinic-referred outpatients, 6-12 years of age, were given a diagnosis of Attention Deficit Disorder with Hyperactivity(ADD+H) or without Hyperactivity(ADD-H). Comparisons of behavioral measurement by Conners Rating Scale(CRS) and Home/School Situations Questionnaire(HSQ/SSQ) revealed that the children with ADD+H displayed more pervasive behavior problems at home and school than the children with ADD-H. Also the children with ADD+H were more likely to be delinquent and aggressive compared to the children with ADD-H when using the Child Behavior Check-list(CBCL) for parents Hyperactivity symptom in ADHD is highly correlated with aggression scale on CBCL These finding suggest that ADD+H and ADD-H may differ in clinical disease entity.

The purpose of this study is to investigate the lifestyle factors influencing behavioral problems such as Inattention, hyperactivity/impulsivity, and internet overuse in elementary and middle school students. Data from 889 elementary school students and 676 middle school students were used and teacher reporting on students' attention deficit and hyperactivity and impulsivity symptoms was also included in the analysis. Lifestyle included opportunities for family interaction, sleep, watching TV, playing Video games, eating breakfast, eating junk food, and private education. As a result of stepwise regression analysis, Video games, junk foods, and family interactions significantly predicted the inattention of elementary and middle school students. Video games, TV, junk foods, and family interactions significantly predicted elementary school students' hyperactivity and impulsivity, but the lifestyle variables hardly accounted for the hyperactivity/impulsivity of middle school students. Video game, and family interactions significantly predicted Internet overuse for both elementary and middle school students. Current study suggest that family interaction opportunities and the use of video games, TV and junk food should be considered to intervene in behavior problems.

A 12-year-old girl with a 6 year history of childhood-onset schizophrenia required 2 hospitalizations and long-term clozapine trial due to inadequate responses to combinations of typical neuroleptics and traditional treatments of schizophrenic disorder. On admission, she had continuous auditory and visual hallucinations, persecutory delusion, emotional instability, regression of behaviors including temper tantrums as well as specific developmental delays in learning, language, and motor coordination. The clozapine trial significantly reduced most of the positive symptoms, and facilitated in successful discharge from the hospital. During the 4 year clozapine treatment, no significant adverse reactions were noted, and she returned to a structured school setting with minimal degrees of schizophrenic symptoms. From this clinical experience, we suggest that clozapine might be safe and effective in treating treatment-refractory schizophrenic children.

Object：The purpose of this study was to investigate that infection with group $A[{\beta}]$ hemolytic streptococcus may associate the mechanisms that cause or exacerbate the tic symptoms in some cases of Tourette's disorder Method：Fourteen cases with abrupt worsening of tics participated in this study：10 males,4 females. The subjects were divided into two groups composing of the group with increasing level of ASO titer and the group with normal level of ASO titer. The subjects were administered Yale Global Tic Severity Scale(YGTSS). Result：The global severity scores and overall TS impairment rating scores of YGTSS in the group with increasing level of ASO titer were more higher than in the group with normal level of ASO titer Conclusion：These results suggest that increasing level of ASO titer, resulting from group $A[{\beta}]$ hemolytic streptococcal infection has affected worsening the tic symptoms in Touette's disorder.

The purpose of this research was to investigate the prevalence of peer harassment in preschool children and assess its influence on self-concept, hyperactivity, and behavioral problems. The participants were 4 and 5 year old children recruited from preschools and day care centers. Results indicated that a small group of children were identified as victims by self and teacher-reports. Negative self-concept and hyperactivity predicted self-reported victimization. In addition, hyperactivity, internalizing, and externalizing problems were significant contributors in teacher reported victimization.

The purpose of this study was to identify the characteristics and the attributes related to Internet use in patients with Internet addiction. This study is a descriptive secondary analysis study, at Internet addiction clinics used the data of 63 patients diagnosed with Internet addiction. Data were obtained from Internet addiction clinic Electronic Medical Records(EMR), there was included the Korean Internet addiction scale(K-scale), Beck Anxiety Inventory(BAI), Beck Depression Inventory(BDI), Barratt Impulsivity scale(BIS), Conners ADHD Rating Scale(CAARS), Lubben Social Network Scale(LSNS). K-scale had significantly correlations with Internet use time per day, anxiety, impulsivity, Attention deficit Hyperactivity Disorder(ADHD) symptom. In stepwise multiple regression, factors significantly affecting ADHD symptom (${\beta}=.37$), Internet use time per day(${\beta}=.29$), Impulsivity(${\beta}=.25$), which accounted for 44% of the variance. Results indicate that patients with Internet addiction had psychological difficulties and suggest that children with ADHD needed to intervention for appropriate internet use.

The purpose of this study is to develop a family resilience program for families of children with ADHD. For this purpose, a preliminary program was developed as a pre-program development stage and its effectiveness was evaluated. To develop a preliminary program, a prior study was reviewed before developing the program, which was carried out. The program was conducted after recruiting seven mothers of children diagnosed with ADHD. It was operated for a total of eight sessions, two times a week, for 120 minutes. A single system design was designed to assess the effectiveness of the developed Family Resilience program. Then, the Family Resilience goals of the individuals set by the research participants were measured. The results of the study showed a slight increase in scores for all participants in the program. By discussing the effects, limitations and suggestions of the developed preliminary program, we hope that a family resilience program for families of children with ADHD will be developed based on this preliminary program research.

본 논문은 주가(株價)의 변동성검증모형(變動性檢證模型)을 한국주식시장(韓國株式市場)에 적용하여 시장의 효율성을(效率性) 검증하였다. 1975년부터 1990년까지 의 17년 기간중 Shiller[81a], Mankiw-Romer-Shapiro[85], West[88b]의 모형을 이용하여 검증한 결과, 높은 수준의 과잉변동성(過剩變動性)이 발견되었다. 그러나 이러한 주가의 과잉 변동성을 시장이 비효율적이라는 증거로 간주하기는 어렵다. 왜냐하면 이들 모형의 가정 중의 하나인 할인율이 일정하다는 가정을 완화시켜 다시 검증한 결과는 오히려 과잉변동성 중에서 많은 부분이 감소하는 것으로 나타났기 때문이다. 다시말해서 주가에 과잉변동성이 존재하는 것은 시장이 비효율적이라기 보다는 기간에 따른 할인율의 변동폭이 큰 데에 원인이 있는 것으로 해석된다. 따라서 할인율(割引率)의 변동원인(變動原因)을 조사하여 주식시장의 효율성을 분석하였다. 주가의 일부는 랜덤웍의 요소에 의해 결정되고, 나머지 일부는 평균회귀(平均回歸) fads(mean reverting fads)에 의해 결정된다고 가정하여 검증한 결과, 후자에 의해 설명된 비율이 매우 높게 나타났다. 즉 한국주식시장에서의 투자자는 교란거래(攪亂去來)(noise trading)나 피드백거래(去來)(feedback trading) 등의 비합리적인 투자행동을 취하고 있으며, 이러한 비합리적인 행동에 의해 주가변동의 $60{\sim}80%$가 설명되는 것으로 보인다.

This study presents the behavioral and cognitive changes by administration of methylphenidate(MPH) and imipramine(IMI) for the treatment of attention-deficit hyperactivity disorder(ADHD) in $5_{1/2}{\sim}12$ years old children referred to child psychiatric clinics. Behavioral changes are assessed with parent's and teacher's ratings. Drug effects on attention. short-term memory, and impulsivity are evaluated with psychological tests in laboratory. The changes were assessed twice in a 8-week periods. The data were analyzed seperately for 15 subjects each drug using repeated measured analysis of variance(ANOVA). The findings indicates that behavioral and cognitive impairments are improved by both drugs, but impulsivity is not. And MPH is superior to IMI on the improvement of attentional problem ; especially the findings indicates important differences between simple task and complex. perceptual-search task. These data confirm the effectiveness of MPH for treatment of ADHD, also raise questions regarding assessment method of attention and impulsivity as fell as importance of impulsivity in ADHD.
