말소리의 생성 및 전달에서 화자의 청각적 피드백은 말소리 발달에 중요한 부분을 차지한다(고도흥 외, 2000). 그러나 청각장애 아동의 경우, 청각적인 피드백이 부족하여 말소리 발달과 언어발달에서 지체를 보이게 된다. 특히 이러한 말소리 발달은 아동의 말명료도에 큰 영향을 미치게 되고, 국내외 여러 학자들은 청각장애 아동의 말 산출에 대한 연구를 활발하게 하고 있다. 그러나 현재 국내의 연구 중 이중모음에 대한 연구는 거의 없는 실정이다. 국내의 청각장애 성인이나 아동을 대상으로 한 연구들은 대부분 연구자의 지각적이고 주관적인 입장에서 이루어지고 있다. 좀더 객관적인 연구 자료는 임상적인 목적뿐만 아니라 말소리 발달의 연구에서 필요하다. 따라서 이 연구는 청각장애 아동의 이중모음의 특징을 음향음성학적인 방법으로 객관적으로 분석하여 그 자료를 제시하고, 건청 아동과의 비교를 통해 임상적인 자료를 제시하고자 한다.

Objectives：The purpose of this study was to investigate the characteristics and differences of brain function in pervasive developmental disorder and developmental language disorder. Method：The subjects were composed of 14 cases of pervasive developmental disorder and 13 cases developmental language disorder. They were investigated by technitium-99m-EDC SPECT. All SPECT were visually assessed by two nuclear medicine specialists, and then quantified by region of interest including temporal, parietal cortex, thalamus, basal ganglia and cerebellum. Result：In both groups, cerebral blood flow was decreased in the temporal, parietal cortex, basal ganglia, thalamus, cerebellum by visual assessment. There was no significant difference between the 2 groups by quantitative and qualitative assessment. Conclusion：These results suggest that pervasive developmental disorder and developmental language disorder are caused by defects in the interneural connection and that both disorders are spectrum disorders.

Children with language developmental disabilities often struggle through their lives from a lot of challenges in everyday life and social activities. They're often easily deprived of the opportunity to engage in social activities, because they find difficulty in understanding or using language, a core means of communication. With regard to this issue, AAC(Augmentative and Alternative Communication) can be an effective communication tool for children who are suffering from language disabilities. In this paper, we propose a deep learning-based AI service to make full use of the pictogram as an AAC tool for children with language developmental disabilities to improve not only the ability to interact with others but the capacity to understand language. Using this service, we strive to help these children to more effectively communicate their intention or desire and enhance the quality of life.

This study the awareness and the demands of the parents on the communication level for social participation of the youth with developmental disability were identified and investigated the relation on client's age, detection time of the condition, disability grades, handicapped types, speech therapy period. For the non-parametric test, Man-Whitney U test, and Kruskal-Wallis test were performed and for post-hoc test, Scheffe test was performed. The results of this study was that the significant difference was found in the awareness and the demand of the communication level of the youth with developmental disability according to the age of children, time of discovery, disability grade, type of disability and speech therapy period. In conclusion, the speech therapy for the youth with developmental disability should be made in the dimension of communication for the purpose of social participation. The follow-up research to emphasize the social support and the institutional backup will be required.

Objectives : Since the awareness of autism spectrum disorders(ASD) is growing, as a result, it is increasing numbers of infants and toddlers being referred to specialized clinics for a differential diagnosis and the importance of early autism spectrum disorders detection is emphasized. This study is to know the difference between ASD and intellectual disability(ID) from comparison of the demographics, clinical characters and obstetric complications. Methods : The participants are 816 toddlers who visited the developmental delay clinic(DDC) in National Health Insurance Ilsan hospital. The number of toddlers diagnosed as ASD and ID was 324 and 492. 75 toddlers out of 114 who returned to DDC were diagnosed as ID at the first visit but 7 of them had changed diagnosis to ASD at the second visit. After compared ASD with ID from the first visit, we analyzed characters of toddlers who had the changed diagnosis to ASD at the second visit. Results : As a result, the comparison between ASD and ID at the first visit shows that the boys have higher ratio, lower obstetric complication and lower language assessment score in ASD. The toddlers who had the changed diagnosis at the second visit were all boys and they had more cases of family history of developmental delay and had lower score of receptive language developmental quotient. Conclusions : These findings suggest that sex, language characteristics and obstetric complication could be useful in the early detection of ASD.

발달 장애 아동은 사회생활을 위한 언어 훈련을 진행하고 있다. 언어 훈련은 상황에 맞는 질문에 대한 답변과 행동을 위한 교육이다. 본 연구는 발달 장애 아동의 발음학습을 위해 가상상담 시스템 구축 방법론을 적용한다. 발달 장애 아동 교육을 위해서는 각 상황에 맞는 질문과 답변 등을 구성하여 교육한다. 가상상담 구축도 시나리오 형태로 시스템을 구축한다. 본 연구는 가상상담 시스템 구축 방법론을 활용하여 발달 장애 아동 발음학습을 구현하는 방법을 제시하도록 하겠다.

Purpose : The study aimed to evaluate the efficacy of auditory brainstem response(ABR) as a screening tool in children with speech and language disorders. Methods : Between January 1, 1999 and December 31, 2001, 139 patients with chief complaints of speech and language delay were recruited from the pediatric neurology clinic, Kyungpook National University Hospital, Daegu, Korea. They had ABR on entry and the clinical data were then analyzed. Results : Fifteen out of 139 cases(10.8%) showed abnormal findings; seven had pervasive developmental disorders, four had developmental language disorders, and four were noted to have other conditions. Among them, seven cases were noted to have conductive hearing loss and eight had sensoryneuronal hearing loss. We also evaluated the normal values in children at the ages of 18 months to seven years. The mean latency of wave I and V were $1.40{\pm}0.13$ and $5.57{\pm}0.26$ respectively. Interpeak latency of I-V was $4.18{\pm}0.24$. Conclusion : Based on these findings, ABR has proved to be a highly sensitive and specific index of hearing impairment. It should be used as a screening tool in children with speech and language disorders.

The purpose of this study is to analyze the general characteristics, effect size, and qualitative indicators of self-advocacy studies of people with developmental disabilities published in domestic academic journals and theses. For this purpose, among a total of 2153 papers related to self-advocacy published from 2000 to 2023, 41 studies with developmental disabilities as the keyword were selected, and the specific research results are as follows. Based on the results of this study, when developing a language intervention program related to self-advocacy for people with developmental disabilities, it is recommended to develop an intervention program based on the number of sessions of 10-19 in a learning situation with 20-30 people in adolescents and adults, or during the transition period. There are many studies limited to educational aspects such as special education and integrated education, and by applying this, it is hoped that a self-advocacy language intervention program will be developed at the level of language rehabilitation that can effectively and sophisticatedly assert self-assertion and self-rights after experiencing difficulties in communication.

The pathophysiology of developmental language disorder is a highly controversial matter. In order to investigate the neural mechanisms involved in developmental language disorders, the authors studied three dimensional regional cerebral blood flow(rCBF) using Tc-99mH-MPAO in 42 children with developmental language disorders. The results are summarized as follows : 1) 61.9% (26/42) of this series revealed decreased perfusion in SPECT. 2) Regions of hypoperfusion were seen in cerebral cortex(47.6%, 20/42), thalamus(33.3%, 14/42), basal ganglia(11.9%, 5/42) and cerebellum(7.1%, 3/42). This study suggests that developmental language disorder could be due to specific functional impairment of the local brain regions which could not detected by conventional investigations such as brain CT or EEG.
