Objective : The aim of this study was to examine the relationship between IgE-mediated atopic dermatitis and attention deficit hyperactivity disorder(ADHD) in Korean children. Method : This case-control study included 69 patients with atopic dermatitis and 42 normal students. Diagnoses of atopic dermatitis and assessments of its severity were made by the dermatologist. The MAST tests were administered to atopic dermatitis patients. The parents of all of the subjects completed the parent versions of the ADHD Rating Scale-IV(ARS). Results: Compared to the normal control group, the atopic dermatitis group scored significantly higher in the total, inattention, and hyperactivity/impulsivity profiles of the ARS(t=3.35, p<0.01 : t=6.41, p<0.01 ; t=3.93, p<0.01, respectively), The atopic dermatitis patients with ADHD hyperactivity/impulsivity subtype showed more severe symptoms of atopic dermatitis than those with ADHD inattentive subtype. The MAST-positive atopic dermatitis patients showed significantly increased incidence of ADHD symptoms than the MAST-negative counterparts. Conclusion : The results of this study suggest the possibility of an association between IgE-mediated atopic responsiveness and ADHD symptomatology.

Objectives : This study was conducted to investigate the association between the symptoms of boys with attention-deficit hyperactivity disorder (ADHD) and the attention-deficit hyperactivity symptoms, temperament and character patterns of their parents. Methods : Forty-five boys with ADHD and who met the DSM-IV criteria were evaluated by using the ADHD rating scale (ADHD-RS), and their parents completed the Korean Adult ADHD scale (K-AADHDS) and the Temperament and Character Inventory (TCI). Results : The parental K-AADHDS scores were not associated with the ADHD-RS total score and the subscale scores of their siblings. The most potent variable related to the ADHD-RS total score was the maternal self-directedness, and the second was the maternal persistence. The maternal self-directedness was the variable that was most correlated with the hyperactivity/impulsivity subscale scores of the ADHD-RS. Conclusion : The results suggest that the paternal ADHD symptoms may not be related to the ADHD symptoms of boys with ADHD. Higher maternal self-directedness and persistence may decrease overall the ADHD symptoms of these boys, and higher maternal self-directedness itself may predict lower hyperactivity/impulsivity symptoms of the boys with ADHD.

Objective : The purpose of this study was obtaining data on the efficacy and safety of risperidone in child and adolescent psychiatric patients. Method : Thirty one children and adolescents (males n=18, females n=13, age ranged from 5.4 to 17.3 years) treated with risperidone were selected among child and adolescent psychiatric inpatients of Seoul National University Hospital from January, 2001 to June, 2002, and charts for them were reviewed retrospectively. Results : The primary psychiatric disorders treated with risperidone were schizophrenia and other psychosis, bipolar I disorder with psychotic features, Tourette's disorder, autism spectrum disorders, mixed receptive and expressive language disorder, attention deficit-hyperactivity disorder, conduct disorder and obsessive-compulsive disorder. twelve of these had comorbid mental retardation. Primary target symptoms of risperidone were psychotic symptoms (n=13 or $41.9\%$), behavioral symptoms (n=10 or $32.3\%$) including aggression, impulsivity, hyperactivity, stereotypy nonresponsive to other psychiatric treatments, and chronic and severe tics (n=8, $25.8\%$). The efficacy of risperidone was measured by clinical global improvement (CGI) for target symptoms, $67.7\%$ of subjects showed moderate or marked improvements and its therapeutic effect appeared to be maintained during at least 7.5 months. Mean daily dosage of risperidone was $0.05{\pm}0.01mg/kg$, the group with psychotic symptoms had significantly higher mean daily dosage (0.07mg/kg) compared with other two groups (0.04mg/kg) with behavioral symptoms or tics. A variety of adverse events were reported in this study : weight gain (n=23) most commonly reported, extrapyramidal symptoms (n=15), autonomic symptoms (n=6), sedation (n=5) and symptoms related to hyperprolactinemia (n=2) etc. Although there was no drug change related to the adverse events of risperidone, and $90\%$ of subjects at their last visits were maintained on it, thus its tolerability appeared good. Conclusions Results suggest that risperidone may be relatively safe and effective drug in managing a wide variety of child and adolescent psychopathologies such as psychotic symptoms, behavioral symptoms including aggression, impulsivity, hyperactivity and stereotypy nonresponsive to other psychiatric treatments, and chronic and severe tics. Controlled and long-term studies of efficacy and safety of risperidone treatment for children and adolescents are recommended in the future.

Behavioral characteristics of Attention Deficit Hyperactivity Disorder (ADHD) are aften observed in normal children. As a result, it is at times difficult to distinguish behavior disorder of clinical significance and normal developmental phenomenon. In addition, symptoms of ADHD can vary greatly depending on situations and social context, creating considerable difficulties in assessment. Therefore it is important to obtain information from various sources and in diverse situations. It is also desirable to quantify the severity of the problems whenever possible and determine their clinical significance by comparing the data to developmental norms. Specifically, various assessment methods such as interview with parent and child, behavior rating scales, behavioral observation and psychological testing were reviewed with discussion on merits and limitatious of each. It was emphasized that systematic and comprehensive assessment utilizing appropriate methods is necessary for accurate diagnosis and treatment evaluation of ADHD.

The purpose of this study is to examine the associations among attention deficit/hyperactivity, social withdrawal, peer relationships, and depression in early adolescence. Gender differences in the associations were also examined. This study investigated these relationships and the gender differences using structural equation modeling multi-group analysis. The third wave data from Korea Children and Youth Panel Survey (KCYPS) of fourth graders were analyzed. The results indicated that attention deficit/hyperactivity had significant effects on depression directly and indirectly through social withdrawal and peer relationships. These results suggest that new programs should be developed to prevent or alleviate depression associated with attention deficit/hyperactivity among adolescents. Specifically, social withdrawal and peer relationships need to be emphasized in planning prevention or intervention programs to promote mental health of adolescents with attention deficit/hyperactivity.

Diagnosis of nutrient disorders in cultivating crops is based on the visual symptoms and results of soil and plant analysis. This study was carried out to investigate the influence of B concentrations in fertilizer solution on the growth of and nutrient uptake by domestically bred strawberries. Tissue analysis based on the dry weight were also conducted to determine the threshold levels in plants when toxicity developed in boron. The growth was seriously restricted in the three strawberry cultivars as the B concentrations in fertilizer solution were elevated. The fresh and dry weights were heavier and crown diameters were thicker in the 0.25 mM boron treatment than the other treatments tested. The toxicity symptoms of boron appeared on the older leaves of three strawberry cultivars while interveinal chlorosis symptoms appeared on the young leaves of 'Keumhyang' and 'Seolhyang' strawberries. The toxicity symptoms in lower leaves were developed when B concentrations in fertilizer solution were higher than 2 mM in 'Keumhyang' and 0.5 mM in 'Maehyang' and 'Seolhyang' strawberries. The elevated boron concentrations in fertilizer solution did not influence the tissue K, Ca, and Mg contents, but influenced the phosphorus contents with decreasing tendency. The tissue Fe and Zn contents decreased and increased, respectively, as the B concentrations in fertilizer solution were elevated. When the concentration of boron at which the growth of a plant is retarded by 10% is regarded as a upper threshold level, the boron contents based on dry weight of above ground plant tissue should be lower than 25.1, 44.2, and 62.5 $mg{\cdot}kg^{-1}$ in 'Keumhyang', 'Maehyang', and 'Seolhyang' strawberries, respectively.

The present study was designed to investigate variables associated with mother-child interaction patterns of Attention Deficit Hyperactivity Disorder(ADHD), and also to evaluate short-term effects of stimulant medication on the behaviors of ADHD children and their mothers during interaction. 15 ADHD boys(ages 5${\sim}$10 years) were treated with metylphenidate(0.5mg/kg per day) for 1 month, and their behaviors as well as their mothers for the 10 minute free play and 20 minute task performance period were videotaped through one-way mirror. The childrens attention was also evaluated using the Continuous Performance Task(CPT) and ratings of their hyperactive behaviors were obtained from their mother prior to the treatment. The videotaped interaction were rated according to the Response Class Matrix developed by Mash, Terdal & Anderson(1973). Results indicated that percentage of behavior of the mother and child during interaction was highly correlated with each other, which, in turn, was highly correlated with the symptom severity of the ADHD child. That is the more severe the cognitive and behavioral symptoms of ADHD, the more negative the interaction behavior pattern was. After 4 weeks of stimulant medication the mothers as well as the ADHD children showed a significant decrease in the percentage of negative-aggressive behavior during the task performance period. The results indicated that negative interaction behavior of the mothers was in large part a response to the negative behavior of their ADHD children.

The ADHD, a common condition of childhood onset, is of critical educational and social concern at every level of school. Investigating the determinants of teachers' ADHD coaching and their relative importance is important for improving teaching and counseling practice in inclusive education setting. Based on three hundred and fifty three survey responses from elementary, junior and high school teachers, this research examines the impact of knowledge level, facilitating condition, cooperation with parents, attitude of teachers toward teachers' ADHD coaching. Statistical analysis shows that the knowledge level and facilitating condition influence the level of teachers' attitude, and that attitude has some impact on the cooperation level with parents, at 5% significance level. The cooperation with parent, one of two precedence factors of ADHD coaching, was identified to be significant, but attitude was shown to be nonsignificant predictor of ADHD coaching. A brief discussion concerning the critical needs of teachers is also presented.

본 연구는 양액재배에서 영양진단에 기초한 배양액관리를 하기 위해 유효한 수단으로 이용되고 있는 신속하고 간편하며 정확한 즙액분석 방법(질산태질소의 정량방법, 인산정량방법, 즙액추출법, 추출비율, 마쇄시간 및 샘플채취 부위 등)들에 관한 비교검토를 하였다. 'Earl's Favorite 춘계 F$_1$호'를 1993년 1월 11일에 파종하여 본엽 3~4매의 묘를 스티로폼베드내 암면슬라브에 정식하여 비순환방식으로 재배했다. 즙액분석법은 결핍이나 과잉증상이 외관적으로 나타나기 전에 신속하고 간이한 즙액분석법에 의해 작물체의 영양상태를 진단하여 대응이 가능하다고 판단되었다. 즙액분석시 질산태질소의 분석에는 자외부흡광도법, 인산분석에는 바나드몰리브덴산법이 추천되었고, 추출비율은 1:4로, 엽병의 마쇄시간은 60초, 그리고 채취 부위는 일정부위로 하는 것이 바람직하다고 판단되었다. 그러나 샘플채취시간에 대해서는 채취시간에 따른 차이가 크기 때문에 앞으로 보다 상세한 검토가 요청되었다.
