  • The purpose of this study was to examine the reliability and validity of attention deficit disorder evaluation scale-school version(ADDES-SV). Between October 1996 and November 1996, ADDES-SV was administered to 263 elementary school students in the second grade and between Jun 1996 and October 1996, 28 attention deficit hyperactivity disorder patients. In the reliability test, the test-retest reliability coefficient was significantly high and that of inattention was 0.88, that of impulsivity was 0.80, that of hyperactivity was 0.83 and total score was 0.83. In the reliability test by internal consistancy, the Cronbach $\alpha$ coefficient was significantly high and that of inattention was 0.98, that of impulsivity was 0.87, that of hyperactivity was 0.87(p<0.05). The half-sprit reliability coefficient by first-second half method showed high correlation and that of inattention was part 1: 0.96, part 2: 0.96 impulsivity was part 1: 0.95, part 2: 0.93, hyperactivity was part 1: 0.92, part 2: 0.94(p<0.05). Inter-rater reliability by pearson correlation coefficient was significantly high and that of inattention was 0.92, that of impulsivity was 0.87, that of hyperactivity was 0.89 and total score was 0.89. The concurrent validity between ADDES-SV and CAP scale was 0.85 in attention deficit hyperactivity disorder patient group and 0.79 in normal control group(p<0.05). In discriminant validity test between attention deficit hyperactivity disorder patient group and normal control group, the patient group showed higher score(p<0.05). The total discriminant capacity of the patient group in ADDES-SV was 94.6%. In this point of view, ADDES-SV scale showed high reliability and validity in applying to Korean subjects and was proved to be the useful screening test tool for attention deficit hyperactivity disorder research.

  • Objectives:This study was conducted to investigate the degree of psychopathologies of the family members of children with chronic convulsive disorder and evaluate the structures and dynamics of those families. Methods:The participant patients and family members were recruited from the population attending the outpatient clinic of department of pediatric neurology in Seoul National University Hospital in Korea. All the patients had idiopathic chronic convulsive disorder. Any patient with mental retardation, pervasive developmental disorder and gross brain pathology was excluded. As controls, normal students were chosen and their sex, age, achievement, socioeconomic status were matched to patients. The author interviewed the children and their family members twice and obtained informations about patient-parent relationship, patient-sibling relationship and others. For in-depth evaluation, we used family environment scales(FES), symptom Checklist-90-revised(SCL-90-R), self administered dependency questionnaire for mother(SADQ). Results:After interviewing with the parents of epileptic children, overprotection of parents, hostile feeling of siblings toward index children were higher than controls. The parental conflict was also more expressed than control families. According to results from FES, the scores of the subscales of expression, achievement-orientation, intelligence-orientation and active recreation were significantly lower than control group. The epileptic children showed higher dependency to parents especially in affection, communication and traveling areas of SADQ than control group. Maternal psychopathologies evaluated by SCL-90-R were much higher than the mothers of controls. According to T scores of SCL-90-R, about 40% of mothers with epileptic children had the risk of clinically significant depressive or anxiety disorders. Conclusion:These results suggested that the family members of epileptic children had more relationship problems and psychopathologies than control group and some mothers might have clinically significant depressive or anxiety disorders. so, effective psychiatric family interventions are needed for resolution of conflict and psychopathologies of family members.

  • Objectives: The purpose of this study was to assess the difference of subjective daytime sleepiness level between primary insomnia patients and healthy control subjects. We also investigated the relationship between subjective daytime sleepiness level and variables of nocturnal polysomnograghic sleep architecture of insomnia patients. Method: Total subjects were 87 patients with primary insomnia diagnosed with polysomnography and 88 normal controls. The daytime sleepiness level in each group was measured by Korean version of Epworth Sleepiness Scale (ESS). The correlations of ESS score and nocturnal polysomnographic variables were calculated in the patient group. Results: Patients with insomnia had the lower ESS scores than the control group. In patients group, the ESS score showed significant negative correlations with total sleep time, sleep efficiency%, and stage 2 sleep time%. The ESS score also showed significant positive correlations with number of awakenings, number of awakenings more than 2 minutes, and wake after sleep onset time. Conclusions: Insomnia patients showed lower level of subjective daytime sleepiness that may indicate their higher alertness comparing to control subjects. Daytime sleepiness of patients with insomnia was associated with polysomnographic variables including total sleep time, sleep efficiency%, stage 2 sleep time% and disrupted continuity of nocturnal sleep.

  • Objectives:This study was aimed at examining the emotional predictors of adolescent suicidal ideas in a community. Methods:The subjects were 1909 middle and high school students(936 males, 973 females) in Koyang-shi. We evaluated all subjects using Center for Epidemiologic Study for Depression(CES-D), Revised Children's Manifest Anxiety Scale(RCMAS), Korean-Youth Self Report(K-YSR), Psychological Self-1 of Offer's Self Image Questionnaire(PS-1 of OSIQ) and Suicide Ideation Questionnaire (SIQ). We compared the PS-1 of OSIQ scores of Anxious-depressive group(above cut-off points of CES-D, RCMAS and K-YSR) to those of control group, and conducted correlation analysis and stepwise multiple regression analysis to all subjects. Results:The number of anxious-depressive group was 126(6.58%) among 1909 subjects with significant gender difference(M:F ratio 1:1.5). Both PS-1 of OSIQ and SIQ scores were significantly higher in Anxious-depressive group than in control group. There were significant correlations among the scales:CES-D, RCMAS, A/D of K-YSR, PS-1 of OSIQ and SIQ. Through stepwise multiple regression analysis, we found that significant predictors of suicidal idea were CES-D, RCMAS and A/D of K-YSR. Conclusion:Anxious-depressive adolescents may be the high-risk group for suicidality and need preventive interventions of suicidality in a community.

  • Objectives: An Increased level of psychophysiologic arousal and diminished physiologic flexibility would be observed in patients with panic disorder compared with a normal control group. We investigated the differences of psychophysiologic response between patients with panic disorder and normal control to examine this hypothesis. Methods: Ten Korean patients with panic disorder who met the diagnostic criteria of DSM-IV were compared with 10 normal healthy subjects. In psychological assessment, levels of anxiety and depression were evaluated by State-Trait Anxiety Inventory, Beck's Depression Inventory and Hamilton Rating Scale For Anxiety and Depression. Heart rate, respiration rate, electrodermal response, and electromyographic activity were measured by biofeedback system (J & J I-330 model) to determine psychophysiologic responses on autonomic nervous system. Stressful tasks included mental arithmetic, video game, hyperventilation, and talking about a stressful event. Psychophysiologic responses were measured according to the following procedures : baseline(3 min)-mental arithmetic (3 min)-rest (3 min)-video game (3 min)-rest (3 min)-hyperventilation (3 min)-rest (3 min)-talking about a stressful event (3 min). Results: The baseline level of anxiety and depression, electrodermal response (p=.017), electromyographic activity (p=.047) and heart rate (p=.049) of patients with panic disorder were significantly higher than those of the normal subject group. In electrodermal response, patient group had significantly higher startle response than the control group during hyperventilation (p=.001). Startle and recovery responses of heart rate in the patient group were significantly lower than responses in the control group during mental arithmetic (p=.007, p=.002). In electrodermal response of the patient group, startle response was significantly higher than recovery response during mental arithmetic (p=.000) and video game task (p=.021). Recovery response was significantly higher than startle response in respiratory response during hyperventilation. Conclusion: The results showed that patients with panic disorder had higher autonomic arousal than the control group, but the physiologic flexibility was variable. We suggest that it is helpful for treatment of panic disorder to decrease the level of autonomic arousal and to recover the physiologic flexibility in certain stressful event.

  • 대조도와 관용도사이의 손실 교환은 투사 방사선 촬영에 있어서 잘 알려져 있고 또한 오랫동안 지속되어온 영상의 질에 있어서의 제약이었다. 전자적인 영상획득의 도입으로 한 영상 내에 넓은 영역의 X-Tay 노출을 포획하는 것이 가능해 졌다. 그러나, 진단에 필요한 세부영역 들을 위해 적절한 대조도를 유지하는 반면, 일반적으로 기대되는 관용도 범위 이외의 정보가 시각화 되어지는 것과 같은 영상의 rendering과 displaying의 문제가 남아 있었다. 이 문서에 묘사되는 EVP(Enhanced Visualization Processing)는 이 문제를 중점적으로 다룬다. 방대한 진단용 CR 영상 데이터베이스로부터 선택된 14개의 검사유형 당 각각 5개의 영상들을 포함한, 총 70개의 영상들을 사용하여 임상 보고서가 제출되었다. 각 영상에 대해, control rendering은 현재 개발되어 있는 automatic tone scaling algorithm(자동 톤 스케일 알고리즘)에 의해 생성되었고, test rendering은 그 control of image에 EVP를 인가함에 의해 생성되었다. 10명의 radiologist들은 각자 개별적으로 140개의 이미지들(70개의 test renderings와 70개의 control renderings)을 9점의 진단 상의 품질 척도로 평가했다. EVP는 세부 대조도의 부당한 손실 없이 증가된 노출 관용도를 제공했다. 많은 영상에서 EVP는 과소 투과 영역에서의 정보의 손실을 줄여주고, 반면 과다 투과 영역의 밝게 빛나는 현상을 실제적으로 감소시켰다. 진단상의 품질 평가는 EVP image와 control image 모두 평균적으로 높았다. 그럼에도 EVP images의 평균 등위는 control image의 그것보다 1 단계 완전히 높은 범위에 있는 것으로 평가되었다. 쌍으로 그 영상들을 보면, EVP images의 76%가 일치하는 control images의 평가 단계보다 1 또는 그 이상 높은 범주인 것으로 평가되었고, 반면 control image의 6% 만이 일치하는 EVP 영상보다 우수한 것으로 평가되었다. 유사한 결과가 연구된 14개의 검사유형에 대해 획득되었다.
