Reye syndrome is a rapidly progressive encephalopathy with hepatic dysfunction, which often begins several days after apparent recovery from a viral illness, especially varicella or influenza A or B. Salicylate use was identified as a major precipitating factor for the development of Reye syndrome. With the recommendation to avoid use of salicylates in children, Reye syndrome has virtually disappeared in recent years. We report a case of Reye syndrome in a 5-month-old infant who had been treated with intravenous immunoglobulin and aspirin under the diagnosis of Kawasaki disease, and showed symptoms of sudden onset of irritability, rigidity, decreased activity, vomiting, poor appetite, lethargy, liver dysfunction without jaundice, coagulopathy, and hyperammonemia.

무한 사이버 공간인 인터넷의 발달과 함께 인터넷의 사용이 크게 늘어 거의 대부분이 인터넷을 이용하고 있다. 이러한 인터넷에서의 정보와 지식은 누구나가 어떠한 환경에서도 사용가능해야 한다. 장애인, 노인, 어린이, 약시 등을 고려한 웹 개발이 절실하다. 국내에서는 2008년 4월 11일 "장애인차별금지 및 권리구제 등에 관한 법률" 동법시행령(제14조)에 웹 접근성 의무화 조항 마련을 마련하여 복지 분야 뿐 아니라 인터넷에서도 장애인에 대한 평등을 강화하였다. 매년 웹 접근성 실태조사를 하고 있는 중앙행정기관의 웹 접근성 평균 점수는 2005년 72.3점, 2006년 81.8점, 2007년 88.2점, 2008년 90.6점이고, 광역지자체는 2005년 71.6점, 2006년 81.8점, 2007년 86.8점, 91.6점으로 해마다 향상되고 있는 것으로 나타났다(한국정보화진흥원 웹접근성연구소, 2009). 이와 비교해 볼 때, 민간기업의 웹사이트는 웹 접근성 준수율이 많이 낮으므로 본 연구에서는 한국 미국 일본 50대 기업의 웹 접근성 및 사용성에 대해 나라별, 기업별로 실증 평가 분석하여 문제점을 도출하고 개선안을 제시하여 민간기업의 웹 접근성, 사용성 수준을 향상시키는데 다소라도 기여하고자 하며 향후 IPTV, 휴대폰 등 다양한 웹 접근성 연구 분야에 대해 제시했다.

웹이 대중화되면서, 사용자 계층도 어린이, 노인, 장애인 등으로 다양해졌다. 인지적, 신체적 특징에 상관없이 모든 사람에게 동등한 웹 기회를 제공하고 있는가를 나타내는 지표가 웹 접근성이다. 웹 사이트들이 특정 수준의 웹 접근성을 준수하도록 유도하기 위해 W3C(World Wide Web Consourtium)의 WAI(Web Accessiability Initiative)는 웹 콘텐츠 접근성 가이드라인 WCAG (Web Content Accessibility Guideliens)를 개발하였다. 현재, WCAG2.0까지 발표된 가이드라인은, 4개의 원칙(Principle), 12개의 지침(Guideline), 그리고 61개의 성공기준(Success Criteria)으로 구성 되어 있다. 평가자들은 WCAG2.0에서 제시하는 성공 기준에 맞춰, 웹 사이트가 웹 접근성을 어느 수준으로 준수하고 있는지 평가한다. 하지만, WCAG2.0을 기준으로 웹 사이트를 평가할 경우, 성공기준의 준수여부는 평가가 가능하지만, 특정 사용자 집단의 특성을 반영한, 우선순위가 포함되지 않아, 특정 사용자 집단을 위한 개선 사항을 도출하는데 어려움이 있다. 이에, 본 논문에서는 이러한 점을 고려하여 WCAG2.0 기반의, 특정 사용 집단을 위한 웹 접근성 평가 모델을 제안한다. 사용자 특성에 따라 성공지침들의 중요도가 달라 질 수 있으므로, AHP 기법을 활용하여 성공지침들의 상대적 중요도를 평가하고, 우선순위화 하였다. 평가 모델의 효용성을 입증하기 위해, 특정 사용집단으로 노인 집단을 선정하여, 웹 접근성 평가 모델을 개발하였다.

Purpose: Patients with chronic gastrointestinal disease are at risk for trace element deficiency due to impaired absorption and gastrointestinal loss. The aim of this study was to evaluate the trace element status of patients with gastrointestinal disease by blood and hair analysis, and to determine the usefulness of hair mineral analysis for diagnosing trace element deficiency not detected by a blood test. Methods: An analysis of hair minerals was performed and compared with blood mineral analysis in 13 patients with chronic gastrointestinal disease. The concentration of each element in the hair and blood was compared in the subgroups based on parenteral nutritional support or clinical symptoms. Results: Almost all patients had trace element deficiency. The trace elements deficient in the blood or hair analysis included zinc, selenium and copper. The hair zinc concentration was significantly lower in the group receiving parenteral nutritional support. The hair selenium concentration was statistically associated with the clinical symptoms of hair loss, brittle hair and loss of hair pigmentation. Conclusion: The results of this study suggest that patients with chronic gastrointestinal disease should receive adequate zinc and selenium replacement to avoid trace element deficiency especially when treated with long-term parenteral nutrition. Hair mineral analysis is useful as a complementary tool for the detection of a trace element deficiency.

The malignant tumor in childhood is one of the main causes of children s death due to disease. The traditional treatment for the malignancy is known for the radiation therapy and the chemical therapy or both. However, the treatments tend to induce intraoral complications. Different from adults, almost all children on cancer therapy are expected to have dental complications, because their permanent teeth are on the developmental stage. The degree of dental complication depends on the patient's age, type of chemical and other factors-radiation dose and frequency. In this report, 3 children who had experienced the anti-cancer therapy on their age between 1 and 4 years were selected and dental complications were examined. The children have chance for the various oral complications including the developmental problems such as agenesis, microdontia and hypoplasia of the teeth. Therefore, it's important to understand the side-effects of anticancer therapy during the permanent teeth had been developmental stage in young patients. Also, oral health care specialists, including pediatric and hospital dentist can support the oncology team by providing basic oral care, implementing oral care protocols, delivering emergency dental treatment undergoing anticancer treatment.

The purpose of this study was to test characteristics between normal and autistic children via comparison of nutrient intakes, hair mineral, blood free radical, and serotonin contents. A total of 50 children aged 3-9 were divided into two main groups of normal control children (n=22) and autistic children (n=28) tested by child psychiatrist. The nutrient intakes by 24-hour recall method were no significantly different between the two groups. The concentrations of toxic mineral, such as cadmium (Cd) and lead (Pb) in hair of autistic children were significantly higher, while concentration of antioxidant mineral (Cu, Zn, Fe) was lower than that of normal children. The autistic children had significantly higher concentrations of blood free radical than that of normal children. No significant difference was observed in serotonin concentration between the two groups. Our results suggest a possible role of increased toxic mineral and free radical, both of which may be relevant to the pathophysiology of autism in children with developmental delay.

Self-injurious behavior is often showed in mental retardation, especially in autism. Self-injurious behavior has been regarded as a symptom cluster rather than a disease but it is an emergent clinical situation that can directly affect mortality. This case is about a refractory autistic patient who showed a self-injurious behavior of hitting the head repetitively. He was hospitalized and was treated by pharmacotherapy and behavior therapy and for this reason this clinical experience is reported with literature review. The patient is a 7-year old boy who was ward admitted from 1999 April 20 till July 10 into OO hospital OO ward because of self-injurious behavior. During the 12 weeks he had admission treatment. As for the pharmacotherapy, haloperidol was dosed up from 0.5mg to 1.0mg from the 4th week and combination drug therapy was done during the admission with naltrexone 25-50mg. As for the behavioral therapy, Differential Reinforcement of Other behavior was used and regular play therapy was done. To remove the physical restraint, headgear and hard sleeve was used. Currently, OPD follow up treatment is being done and haloperidol 0.5mg and naltrexone 50mg is maintained. The patient’s mother is educated and play therapy is done an hour daily at home. When the patient was released form the hospital, self-injurious behavior was decreased more than the moderate state and remission state is still being maintained at the outpatient clinic.

Objective : This study was conducted to confirm the effect of the oral motor facilitation technique (OMFT) on oral motor function in stroke patients. Methods : This study was conducted on 72 stroke patients with dysphagia were included. Thirty-six patients were randomly assigned to the experimental and control groups were randomly classified into 36 patients each using a random table, and a two-group pre-post test was designed. The experimental group underwent OMFT, and the control group underwent traditional dysphagia therapy for 30 min, once a day, 5 times a week for 4 weeks, for a total of 20 sessions. The Comprehensive Orofacial Function Scale (COFFS) was used to evaluate oral motor function. Repeated-measures analysis of variance (ANOVA) was performed to confirm the effect of the period, and an independent t-test was performed to analyze the difference in change between the two groups. Results : Total COFFS scores improved in both groups. The experimental group showed significant changes in mandibular and lip movements, cheek blows, and tongue movements. In addition, there were significant differences depending on the intervention period in terms of masticatory distribution, food spillage, swallowing of solid and liquid foods, and voice changes. There were significant differences in the mandibular opening and closing categories between the two groups. Conclusion : OMFT is effective in improving oral motor function in stroke patients with dysphagia and can be used as basic evidence in clinical practice.

The purpose of this study is to find out the characteristics of depressive episode about major depression and bipolar disorder in child and adolescent. The subjects of this study were 34 major depression patients and 17 bipolar disorder patients hospitalized at child and adolescent psychiatry in OO university children's hospital from 1st March 1993 to 31st October 1999. The method of this study is to review socio-demographic characteristics, diagnostic classification, chief problems and symptoms at admission, frequency of symptoms, maternal pregnancy problem history, childhood developmental history, coexisting psychiatric disorders, family psychopathology and family history and therapeutic response through their chart. 1) The ratio of male was higher than that of female in major depressive disorder while they are similar in manic episode, bipolar disorder. 2) Average onset age of bipolar disorder was 14 years 1 month and it was 12 years 8 months in the case of major depression As a result, average onset age of major depression is lower than that of bipolar disorder. 3) The patients complained of vegetative symptoms than somatic symptoms in both bipolar disorder and depressive disorder. Also, the cases of major depression developed more suicide idea symptom while the case of bipolar disorder developed more aggressive symptoms. In the respect of psychotic symptoms, delusion was more frequently shown in major depression, but halucination was more often shown in bipolar disorder. 4) Anxiety disorder coexisted most frequently in two groups. And there coexisted symptoms such as somartoform disorder, mental retardation and personality disorder in both cases. 5) The influence of family loading was remarkable in both cases. Above all, the development of major depression had to do with child abuse history and inappropriate care of family. It is apparent that there are distinctive differences between major depression and bipolar disorder in child and adolescent through the study, just as in adult cases. Therefore the differences of clinical characteristics between two disorders is founded in coexisting disorders and clinical symptoms including onset age, somatic symptoms and vegetative symptoms.
