  • Learning disorders are diagnosed when the individual's achievement on standardized tests in reading, mathematics, or written expression is substantially below that expected for age, schooling, and level of intelligence. Subtypes of learning disorders may be classified into two groups, language-based type learning disorders including reading and writing disorder, and nonverbal type learning disorder (NLD) such as those relating to mathematics & visuospatial skills, and those in the autism spectrum. Converging evidence indicates that reading disorder represents a disorder within the language system and more specifically within a particular subcomponent of that system, phonological processing. Recent advances in neuroimaging technology, particularly the development of fMRI, provide evidences of a neurobiological basis for reading disorder, specifically a disruption of two left hemisphere posterior brain systems, one parieto-temporal, the other occipito-temporal. The former is the reading system for beginner reading, the latter for skilled reading. Compensatory engagement of anterior systems around the inferior frontal gyrus(Broca's area) and a posterior(right occipito-temporal) system is noted in persistent poor readers in long-term follow up study. The theoretical model proposed to explain NLD's source is not right hemisphere damage, but rather the white matter model. The working hypothesis of the white matter model is that the underdevelopment of, damage to, or dysfunction of cerebral white matter(long myelinated fibers) is the source of this disorder. The role of an evidence-based effective intervention in the remediation of children with learning disorder is discussed.

  • Diagnosing reading disorders involves complex procedures to evaluate complex cognitive processes. For an accurate diagnosis, a series of tests and evaluations by human experts are required. In this study, we propose a quantitative tool to diagnose reading disorders based on natural reading behaviors using minimal human input. The eye movements of the third- and fourth-grade students were recorded while they read a text at their own pace. Seven machine learning models were used to evaluate the gaze patterns of the words in the presented text and classify the students as normal or having a reading disorder. The accuracy of the machine learning-based diagnosis was measured using the diagnosis by human experts as the ground truth. The highest accuracy of 0.8 was achieved by the support vector machine and random forest classifiers. This result demonstrated that machine learning-based automated diagnosis could substitute for the traditional diagnosis of reading disorders and enable large-scale screening for students at an early age.

  • Objectives : The purpose of this study is to examine the effects of treatment with scalp acupunctures for children with learning disorders. Methods : For this study, we evaluated Korea standard progressive matrices test (K-SPM) on 24 children with learning disorders who visited Korean medical center neuropsychiatry outpatient clinic from July 2012 to January 2013. Scalp acupuncture, cognitive enhancement therapy and speech-language therapy were applied. All children were treated 2 times a week for 4 months and we compared K-SPM test scores before treatment and 30 times after the treatment. Results : 1) After the treatment, K-SPM test scores have increased significantly (p<0.05) and the number of children in grade 5 (<5%) have decreased from 14 to 6. 2) Comparing K-SPM test scores between two groups: one with medical history and the other without medical history, the scores in both groups have increased significantly (p<0.05). 3) We also divided the children into two groups according to age: under the age of 13 and over the age of 13, and compared K-SPM test scores. Although the scores in both groups have increased respectively, it is the scores of the former group (under the age of 13) that have increased significantly (p<0.05). Conclusions : The treatments with scalp acupunctures were shown to be an effective intervention when improving K-SPM test scores of children with learning disorders.

  • Currently, polysomnography is essential to diagnose sleep-related breathing disorders. However, there are several disadvantages to polysomnography, such as the requirement for multiple sensors and a long reading time. In this paper, we propose a system for predicting the severity of sleep-related breathing disorders at home utilizing measurable elements in a wearable device. To predict severity, the variables were refined through a three-step variable selection process, and the refined variables were used as inputs into three machine-learning models. As a result of the study, random forest models showed excellent prediction performance throughout. The best performance of the model in terms of F1 scores for the three threshold criteria of 5, 15, and 30 classified as the AHI index was about 87.3%, 90.7%, and 90.8%, respectively, and the maximum performance of the model for the three threshold criteria classified as the RDI index was approx 79.8%, 90.2%, and 90.1%, respectively.

  • Learning disabilities (LD), also known as learning disorders, refers to cases in which an individual experiences lower academic ability as compared to the normal range of intelligence, visual or hearing impairment, or an inability to peform learning. Children and adolescents with learning disabilities often have emotional or behavioral problems or co-existing conditions, including depression, anxiety disorders, difficulties with peer relationships, family conflicts, and low self-esteem. In most cases, attention deficit and hyperactivity disorder coexists. As learning disabilities have the characteristics of a difficult heterogeneous disease group that cannot be attributed to a single root cause, they are diagnosed based on an interdisciplinary approach through medicine and education, such as mental health medicine, education, psychology, special education, and neurology. In addition, for the accurate diagnosis and treatment of learning disabilities, the diagnosis, prescription, treatment, and educational intervention should be conducted in cooperation with doctors, teachers, and psychologists. The treatment of learning disabilities requires a multimodal approach, including medical and educational intervention. It is suggested that educational interventions such as the Individualized Education Plan (IEP) and the Response to Invention (RTI) should be implemented.

  • 본 논문에서는인공지능(AI; Artificial Intelligence)알고리즘을 활용한 조음 장애 아동들의 '개인화된 맞춤형 학습' 모바일 애플리케이션을 제시한다. 조음과 관련된 빅데이터(Big Data)를 수집-정제-가공한 데이터 셋(Data Set)으로 학습자의 조음 상황 및 정도를 분석, 판단, 예측한다. 특히, 인공지능 활용 시 기존 애플리케이션에 비해 어떻게 개선되고 고도화할수 있는지를 UX/UI(GUI) 측면에서 바라보고 프로토타입 모델을 설계해 보았다. 지금까지 시각적 경험에 많이 치중해 있었다면, 이제는 데이터를 어떻게 가공하여 사용자에게 UX/UI(GUI) 경험을 제공할 수 있는지가 중요한 시점이다. 제시한 모바일 애플리케이션의 UX/UI(GUI)는 딥러닝(Deep Learning)의 CRNN(Convolution Recurrent Neural Network)과 Auto Encoder GPT-3 (Generative Pretrained Transformer)를 활용하여 학습자의 조음 정도와 상황에 맞게 제공하고자 하였다. 인공지능 알고리즘의 활용은 조음 장애 아동들에게 완성도 높은 학습환경을 제공하여 학습효과를 높일 수 있를 것이다. '개인화된 맞춤형 학습'으로 조음의 완성도를 높여서, 대화에 대한 두려움이나 불편함을 갖지 않길 바란다.
