The prosody of children with autism spectrum disorders (ASD) has several abnormal features, including monotonous speech. The purpose of this study was to compare acoustic features between an ASD group and a typically developing (TD) group and within the ASD group. The study also examined audience perceptions of the lengthening effect of increasing the number of syllables. 50 participants were divided into two groups (20 with ASD and 30 TD), and they were asked to imitate a total of 28 sentences. In the auditory-perceptual evaluation, seven participants chose sentence types in 115 sentences. Pitch, intensity, speech rate, and pitch slope were used to analyze the significant differences. In conclusion, the ASD group showed higher pitch and intensity and a lower overall speaking rate than the TD group. Moreover, there were significant differences in s2 slope of interrogative sentences. Finally, based on the auditory-perceptual evaluation, only 4.3% of interrogative sentences produced by participants with ASD were perceived as declarative sentences. The cause of this abnormal prosody has not been clearly identified; however, pragmatic ability and other characteristics of autism are related to ASD prosody. This study identified prosodic ASD patterns and suggested the need to develop treatments to improve prosody.

Tic disorder including Tourette's disorder is a neurodevelopmental disorder that appears in childhood and characterized by the presence of motor and vocal tics. Childhood-onset obsessive-compulsive disorder (OCD) is suggested to be a phenomenologically and etiologically distinct subtype of OCD, bearing a close genetic relationship to tic-disorders. Tourette's disorder and OCD are comorbid in $40-75\%$ of patients initially diagnosed with either disorder. Basal ganglia and cortico-striato-thalamic circuits are implicated in the pathophysiology of both disorders and these disorders have similar clinical features. Over the past decades, the progress in research on Tourette's disorder and OCD has been extraordinary. This review describes some of important insights from these work, involving these areas : 1) clinical implication 2) genetics and epidemiology 3) brain imaging study 4) neuroche-mistry 5) pediatric autoimmune neuropsychiatric disorders associated with streptococcal infection (PANDAS).

수면은 우리 삶의 많은 부분을 차지하는 중요한 삶의 영역이다. 그러나 여러 가지 원인으로 인하여 많은 현대인들이 수면의 즐거움을 제대로 누리지 못하고 있다. 미국의 경우 수면 장애에 의한 졸리움증으로 생기는 사회적ㆍ개인적 손실의 규모를 연간 약 150억 달러로 추정하고 있을 정도다. 우리나라 성인 중에 수면 장애의 하나인 불면증을 경험한 사람의 비율은 73.4%나 될 정도로 광범위하게 나타나고 있지만 정작 그 해결책을 찾지 못하고 있는 실정이다. 수면장애에는 크게 불면증을 보이는 수면 장애, 낮에 과도한 졸리움을 일으키는 수면 장애, 자다가 이상한 행동을 보이는 수면 장애로 구분되어지는데 우리가 일상에서 인식하는 수면 장애는 불면증 정도로 그치는 것이 일반적이다. 더욱이 이러한 수면 장애를 해결하는 방법의 이해 부족으로 수면제나 담배, 술 등에 의존하기 쉽고 단순히 잠을 자야 한다는 강박관념에 시달려 오히려 증상을 악화시키는 경우가 많다. 그러나 수면 장애를 올바르게 이해하고 있다면 그 해결 방안은 의외로 간단하다. 우리의 몸속에 있는 생체 시계의 주기를 규칙적으로 맞추어 가는 것이 중요하다. 또한 수면은 신체적인 요소보다는 정신적인 요소가 많이 작용하기 때문에 무엇보다도 편안한 마음가짐과 무의식적인 수면 유도가 필요하다.

후각장애를 가져오는 질환에는 비, 부비동 질환, 두부외상, 상기도 감염, 간질 및 노인성치매 등의 신 경게 질환, 칼만증후군과 같은 대사성 질환 등이 있으나, 현실적으로 후각장애의 정도를 측정하기가 쉽 지않고, 후각역치가 개인간에 차이가 많아 아직 연구가 미진한 상태이다. 특히 교통사고나 산업현장에서 쉽게 접할 수 있는 두부외상이나 독성화학물질 등에 의해 후각장애가 많이 나타나고 있으나 아직 보상의 기준이 없어 환자들이 어려움을 겪고 있다. 두부손상 후에 발생하는 후각장애는 병원에서도 놓치기 쉬우며, 알아내더라도 두렷한 치료방법이 없기 때문에 간과되어온 것이사실이다. 그러나, 이런 후각장애 환자들은 집안에서 가스가 새는 것을 느끼지 못하며, 화재로연기가 나더라도 알아차리지 못하고, 음식이 상해도 잘 모르므로 위험에 빠지기가 쉽고, 후각에 이상이 있으면 자연적으로미각도 감소하므로 식욕도 떨어지고, 때로는 우울증에 빠지기도하며, 주부의 경우에는 음식을 만들기가 어렵게 된다. 두부외상을 받은 전체 환자 의 약5 -10%에서 후각장애가 나타나는 것으로 알려져 있으나, 냄새가 나지만 정확히 무슨 냄새인지 이름을 대지 못하거나 어떤 냄새를 다른 냄새와 감별하지 못하는 경우까지 합하면 대개 20-30%로 생각된다. 두부 손상 후의 후각장애의 정도는 얼마나 크게다쳤는 가에 달려있지만, 조금 다치더라도 후각장애가 심한 경우도 있다.

The authors intended to investigate personality characteristics and those influence on the outcome of cognitive behavioral therapy in patients with panic disorder. 167 patients who met DSM-IV criteria for panic disorder were assessed by the PDQ-R(Personality Disorder Questionnaire-Revision) and various self-report tools for assessing symptoms of panic disorder. The effect of therapy was measured by the changes of scores and the end state functioning before and after 12-sessions of CBT. The patients with panic disorder were more likely showed obsessive-compulsive, avoidant and paranoid personality disorder and also Cluster C. If is needed when patients were divided into two groups according to total scores of PDQ-R(high or low personality disorder groups), high personality disorder group showed many evidences for increased psychopathology at the start of treatments, this suggested the close linkage between panic disorder and personality disorder. Interestingly, there were no significant differences between both groups in scores of clinical variables and the end state functioning. In conclusion, although patients with high tendency of personality disorder had more generalized problems at the beginning of treatments, they could improve as much as the patients with low tendency of personality disorder. They can be helped by cognitive behavioral therapy for panic disorder and seem to profit as much as patients with low tendency of personality disorder. If is needed to seek other factors in poor responders for cognitive behavioral therapy.

There has been significant movements in the provision of equal access to library and information services for persons with disability. This study aimed to analyze the use and needs of library services of disabled people with a survey. The survey data revealed that the majority of disabled persons did not visit library and not experience library sol-vices. The main reason was reported that they had poor information about the library services. Also, they did not satisfy the variety, sufficiency, accessibility, up-to-dateness of the materials in general. And there were difference of favorite programs and needs among different kinds of the disabled. Therefore, active guidance and public relations about library services. improvement of accessibility for the disabled by building digital collection, resource sharing and extension of services by building library cooperation network, and the arrangement of librarians for the disabled and education for them should be back up for improving library services for the disabled.

REM sleep behavior disorder is parasomnia characterized by unpleasant dreams and dream-enactment behaviors associated with excessive electromyography activity in REM sleep. This may appear idiopathic or secondary to other neurological or medical conditions. REM sleep behavior disorder, which appears to be idiopathic, most often implies the possibility of later neurodegenerative diseases due to synucleinopathy, so accurate diagnosis is important in predicting prognosis. For the diagnosis of REM sleep behavioral disorder, REM sleep without atonia, which appears in the polysomnography, is essential. Obstructive sleep apnea, trauma-related sleep disorders, and vigorous periodic leg movements during sleep are known as diseases that show dream enactment behavior in elderly patients. Considering that it may be accompanied by other sleep disorders that can mimic REM sleep behavioral disorders, it is important to differentiate sleep

Objectives：This study was conducted to compare the cognitive characteristics and visual-motor coordination ability of children with Asperger’s disorder and with those of children with PDD NOS. Methods：27 children(13 in AS group and 14 in PDD NOS group) were individually assessed using the K-WISC and BGT, and the results of those tests were analyzed. Results：The mean FSIQ of the AS group was significantly higher than that of the PDD NOS group. There was also a large discrepancy between VIQ and PIQ in the PDD NOS, while there was not significant discrepancy in the AS. The AS was distinguished from PDD NOS group by significantly higher scores in Vocabulary and Comprehension subscales and lower score in Block design. Also, when compared with the PDD NOS, the AS showed more difficulties in visual-motor coordination. Conclusion：The AS showed relatively good verbal and learning ability, while the PDD NOS relatively superior ability in visuospatial function and visual-motor coordination. The findings indicated that the K-WISC and BGT might be useful assessment tool to differentiate the AS from PDD NOS.

Background: Sleep-related breathing disorders(SRBD) and periodic leg movements disorder(PLMD) are both common, and are considered as separate sleep disorders. However, both disorders show high comorbidity. SRBD and PLMD can result in excessive daytime sleepiness and insomnia due to frequent sleep fragmentation. So, it is very important to consider the presence of PLMD, when we are dealing with the diagnosis and management of SRBD. The objectives of this study were to determine the incidence of PLMD in patients with SRBD, and to describe any differences between patients with and without PLMD. Method: The authors reviewed the sleep recordings of 106 patients with a final diagnosis of SRBD(obstructive sleep apnea or upper airway resistance syndrome), who underwent full nocturnal polysomnography, including the monitoring of the anterior tibialis electromyogram. All sleep records were recorded and scored using the standard criteria. The data was analyzed by the student t-test. Result: 106 patients(M=76, F=30) were included in the analysis. Data revealed a mean age of $49.5{\pm}13.6$ years, a respiratory disturbance index(RDI) of $22.3{\pm}25.4$/hour sleep, a lowest oxygen saturation of $84.9{\pm}11.3%$, a maximal esophageal pressure of $-41.0{\pm}19.1cmH_2O$, and PLM index(PLMI) of $13.1{\pm}22.4$movements/hour sleep. Forty four percent(47 of 106 patients) had a PLMI of greater than 5 on this study. The mean age of the patients with PLMD was significantly higher than that of the patients without PLMD(p<0.005). Female patients with SRBD accompanied more PLMD(p<0.05). The apnea index of the patients with PLMD was significantly lower than that of the patients without PLMD(p<0.01). The percentage of stage 1 sleep in the patients with PLMD was significantly lower than that of the patients without PLMD(p<0.05). Conclusion: The prevalence of PLMD in the patients with SRBD was high at 44.3%. The patients with PLMD were older and had more high RDI in comparison to the patients without PLMD, which was consistent with previous findings. The authors recommend that more careful consideration of PLMD is required when diagnosing and treating SRBD.
