To investigate psychopathoIogy and executive functions of attention deficit hyperactivity disorder (ADHD) children according to intelligence level, this study included 197 ADHD children who visited the outpatient department of neuropsychiatry of YeungNam University Medical Center, from July 2000 to June 2002. The children were divided into groups based on their intelligence levels. They were compared by the Personality Inventory for Children (PIC), Conncers' Continuous Performence Test (CPT), and Wisconsin Card Sorting Test (WCST). There were significant differences in PIC, on the subscales of verbal development, socialization and autism. In the CPT, there was no significant difference. In the WCST, there were significant differences in the total number of errors, the number of perseverative errors, the number of completed categories and the number of trials needed to complete the first category. Considering these results, the intelligence level of ADHD children is related to their disabilities and behavioral symptoms.Executive functions such as abstract thinking, categorization, working memory and flexibility had significant relationship to the intelligence levels of ADHD children. Therefore, the intelligence level of children with ADHD influences the higher executive functions of regulating attention and information processing rather than attentional functions and capacity alone.

본 연구에서는 굴뚝주변에 위치한 건물에 의한 세류현상을 보다 정확히 모사하기 위해서 전산유체모델을 이용하였다. 계산 신뢰도를 검증하기 위해서 전산모델 계산치와 1993년 Thompson의 추적자 실험에 의한 실측치 및 대기 환경영향평가에 많이 사용되는 ISCST3 모델 계산치와 각각 비교하였다. ISCST3에서는 건물의 영향을 고려하기 위하여 BPIP을 이용, 건물의 높이와 폭을 결정하여 모델링을 수행하였다. 전산유체모델에서는 건물을 형상화시키고 굴뚝에서 오염물질을 배출시켜 확산 계산을 하였다. 전산유체모델로 모사한 결과, 건물의 후면에 wake가 발생하는 것을 볼 수 있었고, wake zone의 길이는 건물 높이의 약 2배가 되었다. 오염물질 농도를 비교한 결과 ISCST에서는 최대 농도값과 착지점이 일치하지 않았으나, 전산유체모델로 계산한 결과는 추적자 실험치와 거의 일치한 값을 나타냈다. This study used the computational fluid dynamic(CFD) for describing a dispersion influenced by building downwash. We compared calculated concentrations with Thompson's tracer experiment and ISCST3 models. In calculating ISCST3 model, BPIP(Building Profile Input Program) was used to estimate building heights & widths corresponding to a specific wind direction. Results show that ISCST3 model is not appropriate to describe the building downwash but CFD model, which calculates the flow fields and dispersions simultaneously, is in good agreement with tracer measurements. In order to describe the dispersion induced by building wake near the stack, it is recommended to use CFD model.

For the evaluation of oncogenesis, progression and prognosis of cancer, CGH is an important technique, because this technique is economic due to utilization of only one probe and lack of culture, screening mathod of whole genome and possibility of retrospective and prospective study. By the CGH, genornic variation of 20 breast cancer tissues, 23 stomach cancer tissues and 16 bladder cancer tissues were analyzed. The results were as followes ; 1. breast cancers The CGH results showed gains on chromosomes 8q(40%), lq(30%), 17q(15%), 20q(15%), 18q (15%), 5p(15%), and 13q(15%). The Deletions were on chromosomes 17p(45%) and 22q(20%). High-level amplifications(green/red ratio >1.5) were noted on chromosomes 1p31, iq, 3q25-qter, 5p, 7q31-qter, 8q, 9q22-qter, 10p, l1p, 11q22-qter, 12p, 12q24, 14g21-qter, 15q23-qter, 17q, 18p, 18q12-qter, 20p, and 20q. By comparison with infiltrating ductal carcinoma, the two medullary carcinomas showed high-level amplification on chromosomes iq3l, lq, 8q, 10p, 11p and 12p. 2. stomach cancers 1) Usual amplification sites of genome were lq, 13q, 17q, 20p,q. 2) 17p was the most common deletion site. The other sites of the deletion were lq, 4q. 3) In intestinal type of stomach cancer, genomic variation is more common than diffuse type. 4) In the cases of no evidence of lymph node metastasis, deletion of 17p is absent but amplification of 8q is obvious in the case of lymph node metastasis. 3. bladder cancers Common amplification of copy numbers of DNA sequences by CGH were seen at 1q, 3q, 4q, 5p, 6pq, 7p, 8q, 11q, 12q, 13q, 17q, 18q and 20pq(more than 20% of cases). High level amplification was noted at 1p32, 3p2l, 3q24, 4q26, 8q21-ter, 11q14-22, 12q15-21, 12q21-24, 13q 21-31, 17q22, and 18q22. Deletions were noted at 2q21-qter, 4q13-23, 5q, 8p12-22, 9pq, 11p13-15 (more than 20% of cases).

This work applies the nonequilibrium molecular dynamics simulation method to study a Lennard-Jones liquid thin film suspended in the vapor and calculates the thermal conductivity by linear response function. As a preliminary test, the thermal conductivity of pure argon fluid are calculated by nonequilibrium molecular dynamics simulation. It is found that the thermal conductivity decrease with decreasing the density. When both argon liquid and vapor phase are present, the effects of the system temperature on the thermal conductivity are investigated. It can be seen that the thermal conductivity of liquid-vapor interface is constant with increasing the temperature.

구본훈,박형배,이희정,송창진,김진성,이광헌 大韓神經精神醫學會 1999 신경정신의학 Vol.38 No.6

서 론: 본 연구는 주의력결핍 과잉행동장애(이하 ADHD) 아동과 정상대조군의 연속수행검사(이하CPT) 결과 양상을 비교하여 CPT의 진단적 유용성을 알아보고자 하였다. 그리고, ADHD 아동의 연령과 성별, 지능, 그리고, 장애의 유형 등과 같은 변수에 따른 CPT의 결과양상을 비교하여, CPT가 ADHD의 어떤 특성을 잘 반영해주는가를 알아보고자 하였다. 대상 및 방법: DSM-Ⅳ의 진단기준에 의하여 진단이 내려진 ADHD 실험군 68명과 정상대조군 30명을 선정하였으며, 두 군간의 연령과 성별을 통제하였다. 실험군과 정상대조군 모두 환아의 부모가 ADHD 평가척도(ADDES-HV)를 작성하였으며, 환아에게 직접 CPT를 실시하였고 지적 능력을 평가하기 위해 K-ABC를 시행하였다. 결 과: 실험군과 정상대조군에서의 CPT 결과 양상을 비교하였을 때, 실험군과 정상대조군 사이에 민감도가 유의한 차이를 나타내었고, 반응 기준도 유의한 차이를 나타내었다(p<0.05). ADHD 아동을 대상으로 연령과 지능의 변화에 따른 CPT의 결과 양상을 비교하였을 때, 연령과 지능이 증가함에 따라 CPT각각의 결과들도 대체로 수행력이 호전되는 경향을 나타내었다. 주의력결핍 과잉행동 장애의 유형을 과잉행동을 동반한 군과 과잉행동을 동반하지 않은 군으로 나누어 비교분석을 한 결과, CPT 각각의 결과에서 유의한 차이는 나타나지 않았다. CPT 결과 양상에 있어서 남녀간 차이점을 비교하였을 때, 오경보오류와 정반응시간의 표준편차, 표준편차의 다양성, 그리고, 민감도가 유의한 차이를 나타내었다(p<0.05). CPT 각각의 8가지 결과 변수들에 대해 판별분석을 실시한 결과, 각각의 결과 변수들에 있어서 진단에 대한 전체 판별력이 모두 50%이상을 나타내었다. 그 중, 정반응시간의 표준편차와 표준편차의 다양성, 그리고, 민감도는 진단에 대한 전체 판별력이 모두 60%이상을 나타내었다. 결론 및 고찰: 이러한 결과들은 CPT가 ADHD의 진단에 있어서 어느 정도의 유용성을 가지고 있다는 점을 보여준다 하겠다. 즉, ADHD에 있어서 CPT는 비교적 선별검사와 같은 목적으로는 유용할 것으로 생각되며, 이는 또한 CPT가 장애의 진단에 있어서 보조적인 검사도구임을 나타낸다 하겠다. Objectives: The purpose of this study was to examine to diagnostic availability of CPT in children with ADHD, and what factors are affected to CPT results in the diagnosis of ADHD. Method: CPT, ADHD scales(ADDES-HV), K-ABC were administered to 68 ADHD patients and 30 normal elementary school students as the control group. Also, ages and sex are controlled between two groups. Results: In the differences of the results of CPT between ADHD patients and normal subjects, attentiveness and risk taking are significantly different(p<0.05). In the differences of the results of CPT between ages in ADHD patients, usually as more aged children are better performances in CPT. Also, in the differences of the results of CPT between intelligence in ADHD patients, usually as higher intelligent children are better performances in CPT. There are no differences of the results of CPT between types of ADHD in ADHD patients. In the differences of the results of CPT between sex in ADHD patients, commission error, hit reaction time standard error, variability of standard error, and attentiveness are significantly different between male and female patients(p<0.05). The correlations between ADHD scales and the results of CPT show that inattention subscale is significantly related to hit, omission error, hit reaction time standard error, and variability of standard error. In the discriminant ability between ADHD patients and normal children by the results of CPT, accuracy rates are more than 50% in all results of CPT. Especially, the accuracy rate of hit reaction time standard error, and the accuracy rate of variability of standard error, and also, the accuracy rate attentiveness are more than 60%. Conclusion: In this point of view, this study suggest that CPT is relatively valuable method in the diagnosis of ADHD. For instances, CPT is more likely to screen the ADHD from normal children, or to use as assisted method of diagnosis of ADHD in clinical settings.

As tools to improve productivity and quality, SPC(statistical process control) and Af'Ctautomatic process control) are used in the instrumental process. In process, we know that a statistical control-in is identified with a process of random variables being independently and identically distributedriid). It IS often difficult in practice to attain a statistical control-in because of systematic time series effects like autocorrelation. When the data are autocorrelated In a process, as the diagnosis, we can use ARIMA procedure. In this thesis, a procedure is introduced to diagnose and identify a statistical control-in/out using ARIMA.
