Objectives：Present study developed the computerized ADHD Diagnostic System(ADS) in order to diagnose ADHD and evaluate treatment effect of it, and conducted a standardization study for ADS. Methods：The normative group was composed of 847 children and adolescents between the age of 5 and 15(boy 429, girl 418) living in the areas of Seoul, Kyunggi-do, and Kangwon-do. 30 ADHD children with age ranged 7 to 9 years were participated present study to evaluate the validity of ADS. To establish the norms for diagnosing ADHD, the means and standard deviations of normative group were used to calculate T-scores for each age group. Results：The reliability coefficient of ADS(Cronbach's ${\alpha}$) was .85. There were significant differences in the measures of ADS except commission error between the normal and the ADHD groups. Three factors were extracted through factor analysis of ADS, which were labelled 'inattention', 'slow information processing' and 'impulsivity'. Discriminant analysis showed that ADS significantly discriminate the normal and the ADHD groups. Percentage of correct classification by ADS variables was 96.7%. Conclusion：These results put together strongly support the reliability and validity of ADS as a diagnostic instrument for ADHD.

1. 서론 o 연구배경 05년 4월에는 생손보 공통의 신체장해분류표 개정시행 및 표준약관개정이 있었으며 05년도까지는 어떤 형태로든지 장애인차별금지법안이 입법화될 것이라고 한다. 따라서 장애인의 보험이 거절되었을 경우 입증책임은 보험회사에 있게 될 것이다. 생명보험업계로서는 공 통 인수지침마련을 통해 민원소지 최소화를 위해 노력했으나 오히려 장애인차별이라는 비난을 받게 되었다. 이에 개정신체장해분류표에 대한 연구 및 언더라이팅적 시각에서의 개선방안 모색이 필요하게 되었다. o 연구방향 신체장해제도는 보험회사 뿐만 아니라 각종 법규 및 정부기관에서 다양하게 운영되고 있다. 이들에 대한 연구 및 특히 보험청약시에 주로 접하게 되는 복지장애(장애인복지법하(下))에 대해 주로 연구하여 이와 개정신체장해분류표를 비교분석 하도록 한다. 그리고 개정신체장해분류표에서 향후에 발생가능한 문제에 대해 업계경험을 토대로 개선점을 강구하도록 한다. 2. 신체장애등급의 이론적 배경 o 신체장애제도의 종류 o 국내법상의 신체장애제도 o 신체장애평가제도 근거법규 o 해외주요국의 신체장애평가제도 3. 우리나라의 장애보장제도 현황 o 국가장애등급과 생명보험 실제지급경험의 연구를 통해 신체장해비교를 통해 장애1급의 주요원인이 질병원인에 있으며 재해원인은 상대적으로 낮은 수준을 보이고 있다. 특히 질병장애의 경우 05년 3월까지 등록된 복지장애에서보다 생명 보험 지급경험에서 훨씬 높은 비율을 나타내고 있음이 05년$1{\sim}5$월 생명보험 장애1급 지급 건의 연구결과 나타났다. 문제는 복지장애와 생명보험약관상의 신체장애의 평가기준이 상이하여 등급간 정도와 신체장해물의 정도의 비교에 표준화된 이론적 근거나 tool이 없다는 것이다. 이에 대해 외국사의 경우에는 장애의 결과보다는 원인질병에 의거하여 그에 따른 후유장애로 나뉘어 인수지침을 두고 있다. o 우리나라의 신체장해 평가방법을 보면 각종 법규나 정부기관에서 사용하는 평가방법을 포함하여 대략 신체장애등급방식과 신체장해율 방식으로 나눌 수 있다. 복지장애는 독자적인 신체장애등급방식으로 장애를 평가하고 있으며 생명보험약관은 05넌4월개정시부터 손해보험의 장기보험에서 기(旣)시행중인 신체장해율방식을 쓰고 있으며 이는 미국의 A.M.A법에 근간을 두고 있다. 상호간의 판정기준이 상이한 상황에서 언더라이팅은 장애의 원인은 고려되지 않은 결과물에 해당되는 신체장해율표만 가지고 인수지침을 세우기 어려우므로 A.M.A법에 대한 연구가 필요할 것이다. 또한 손해보험경험에서 이미 문제로 대두되고 있는 한시장해와 기타 제도적 개선방향을 모색해야 할 것이다. 4. 결론 우리나라에서 운영되고 있는 장해는 원인에 대한 고려나 선천성과 후천성의 구별이 없이 운영되고 있다. 또한 신체장해 평가기준이 너무나 다양하게 운영되고 있어서 기초통계축적에도 어려움이 많다. 보험회사의 사회적 책임의 한계도 존재한다. 따라서 장해의 결과보다는 원인에 대한 연구가 더욱 필요할 것이며 이에 대한 국민의 관심 및 공감대형성이 필요할 것이다.

Although obsessive-compulsive disorder(OCD) affects children, adolescents, and adults whether its juvenile(dhild and adolescent) and adult forms are different subtype of a disorder remains unknown. But there are increasing findings that suggest that juvenile OCD may be unique subtype of the disorder. One proposed subtype is the childhood OCD associated with high comorbidity of tic disorder and increased familial loading for OCD or tic disorder. The other proposed subtype is the childhood OCD and/or tic disorder occuring in association with streptococcal infection(PANDAS). These two subtypes of OCD are unlikely to respond to SSRI due to possible different pathphysiological mechanism. So this paper reviews the characteristics of OCD and therapeutic approaches for treatment resistant OCD in childhood and adolescence. Considering the likely heterogeneity of OCD, the possibility that juvenild OCD may be a variant of the disorder can have important clinical and scientific implications because it may further our understanding of this disorder, its etiology, and perhaps its treatment.

Objective : The purpose of this study is to explore the effectiveness of a perceptual motor program in promoting visual motor and motor control outcomes in a child with Attention-Deficit/Hyperactivity Disorder (ADHD) who is enrolled in an elementary school. Methods : The subject is 8-year-old boy who was diagnosed with ADHD but did not receive medication. Research design is a single-subject A-B-A(follow-up). Baseline and follow-up phase were 3 sessions and intervention phase were 8 sessions. After performing 40 minutes of free play on the baseline A and follow-up A, we used the copying subtest of the Korean Development Test of Visual Perception 2 (K-DTVP-2) for evaluating visual motor integration skill and the rope jumping subtest for motor skill. After providing the perceptual motor activity in intervention phase B, copying and ropejumping were performed. Results : The standard scores of the Copying for measuring visual motor integration skill were poor at an average of 4.7 points at baseline phase A, but maintained an average of 9.6 points at intervention phase B and an below average of 7.7 points at the follow-up phase A. In the Rope jumping for the motor skill, it was increased by 4.3 times in the baseline phase A and 5.9 times in the intervention phase B, but slightly decreased by 5 times in the follow-up phase A. Conclusion : This study suggests that perceptual motor program has a positive effect on visual motor and motor function of ADHD children.

Purpose: To identify the factors associated with poor self-rated health in individuals with acquired visual impairment through classification of such individuals into severe and mild visual impairment groups. Methods: This descriptive, cross-sectional, survey-based study analyzed data from 563 individuals with visual impairment due to acquired causes who had been recruited in the 2017 Korean National Survey on Persons with Disabilities. Results: Individuals with severe visual impairment reported poorer self-rated health. Mild depression (p=.003), and low smartphone use (p=.045) were associated with poorer self-rated health in those with severe visual impairment. The factors associated with poor self-rated health in those with mild visual impairment were comorbidities, low smartphone use (p=.006), needed health information (p=.020), unbalanced diet (p<.001), low weight (p=.024), and lack of health checkups (p=.001). Conclusion: Depression was found to be a predictor of poor self-rated health in individuals with severe visual impairment, which highlights the need for nursing and related healthcare intervention to lower depression in this specific population. Further, promoting social network building and providing health information using smartphones may serve to encourage appropriate health behavior in people with severe visual impairment who have reduced mobility and health literacy.

It is hard to understand the coexistence of giftedness and disorder in an individual, but the twice-exceptional is widely recognized now. Gifted autistic spectrum disorder is one of its subtypes in which giftedness exists with autistic spectrum disorder (ASD) simultaneously. Like other constructs including giftedness, the nature of gifted ASD has not been understood in a fundamental and wholistic manner. This paper suggests a cognitive mechanism of gifted ASD based on the integrated model of human abilities(Song, 2009; Song & Porath, 2005), which explains how giftedness coexists with ASD and interacts with each other, producing the characteristics of gifted individuals with ASD. According to the suggested mechanism, the excessive growth of mental spaces in the brain may cause ASD. The over-grown mental spaces result in excessively strong short-term sensory memory and better facility of processing, promoting internal cognitive activities on one hand, but relative lack of cognitive activities in the real world space results in ASD symptoms on the other hand. The cognitive structure of gifted ASD students also contributes to the presentation of giftedness in specific domains. This study suggests that gifted individuals with ASD need to be discouraged from fully engaging in domains they are interested in or the most confident of, rather to be encouraged to invest their giftedness to overcome their ASD symptoms. This study also provides new perspectives on theoretical and educational approaches for gifted ASD.

Among the employer-supported subscribers to the National Health Insurance Service, 6,797 people with mild disabilities with western ages of 20 and up and who received health checkups were investigated. Of these 6,797 people, 3,186 and 3,611 received health checkups in 2009 and 2013, respectively. Those people who were diagnosed with physical handicaps, brain lesions, visual impairment, hearing impairment, intellectual disabilities, mental disorders, kidney disorders or other disorders according to the classification standard for people with disabilities were classified into disability groups of the 3rd through 6th degrees. The purpose of this study was to examine the dangerous influence of obesity of people with mild disabilities on their hyperglycemia, hypertension and high cholesterol. The items measured in this study were abdominal obesity, body mass index, fasting glucose, total cholesterol, systolic blood pressure and diastolic blood pressure. To look for connections between the obesity level and at-risk groups for each disease, cross tabulation and multinomial logistic regression analyses were utilized. Higher levels of abdominal obesity and BMI were found among those who were male, were younger and had higher incomes. The risks of abdominal obesity and BMI were higher in the abnormal groups for each disease. In 2009, the obesity group whose BMI was higher had a 1.51-fold higher risk of hypertension than the normal group. The abdominal obesity group had a 1.59-fold higher risk of high cholesterol, a 1.26-fold higher risk of hypertension and a 1.54-fold higher risk of hyperglycemia than the normal group. In 2013, the obesity group whose BMI was higher had a 1.72-fold higher risk of high cholesterol and a 1.43-fold higher risk of hypertension than the normal group. Those with abdominal obesity had a 1.59-fold higher risk of hyperglycemia than the normal subjects. As the risk of obesity was higher in those with disabilities than in those without disabilities, the former should be encouraged to undergo health checkups on a regular basis, and the coverage of the health checkups should be extended to keep track of their illness. In addition, appropriate education and concern are both required to prevent obesity.
