난독증자란 지능점수에서 예견하는 것보다 유의하게 낮은 읽기 수준 능력을 가진 사람들이다. 국내의 경우 난독증에 대한 연구가 미진하여 외국의 검사도구를 번역하여 사용하고 있지만, 언어의 경우 민족의 특성과 언어의 특성이 매우 크기 때문에 외국의 검사도구를 그대로 가져오기에는 무리가 있다. 본 논문에서는 난독증 환자를 검사 하고 그 검사 결과에 따라 분석을 할 수 있는 검사도구를 설계하는데 있어 키 반응 검사기의 구현시의 문제점과 문제점을 해결하는 방법을 제시하고자 한다. 다양한 컴퓨터 환경에서의 실험을 통하여 일반적인 키 반응 검사기의 문제점을 보이고 구현한 키 반응 검사기가 검사도구로서의 정확도를 유지하고 있음을 보인다.

난독증은 정상적인 지능에도 불구하고 문장을 읽기가 어려운 독서 장애다. 난독증 진단 방법은 ADHD처럼 증상 체크리스트가 없다. 지적장애를 판정할 때 사용하는 웩슬러 지능검사 같은 전 세계인이 사용하는 아주 보편화된 심리검사도 없다. 미국 진단기준의 최신판인 DSM-5에도 어떤 검사를 해서 기준점수 아래여야 진단할 수 있다고 명확히 써놓지 않았다. 본 논문에서는 이를 해결하기 위해 글자, 단어, 문장, 문단의 단위를 설정하여 화면에 출력하고 아이트래커를 활용하여 읽는 사람의 시선 데이터를 수집하여 히트맵으로 분석한다.

Purpose: The purpose of this study was to investigate the relationships between reading ability and binocular functions, based on self tests through surveys. The possibility of the reading ability tests used in this study as a tool on the determination about vision efficiency was also evaluated. Methods: Through reading ability tests about 138 university students, 72 students (52.2%) of them were first selected. Through self tests about dyslexia and light sensitivity, 38 students (52.7%) of the first selected students were secondly selected, whose extents are more than 3. Binocular tests were carried out about three groups (high, middle, low) of these secondly selected students. Tests about NPCs, distance and near phoria, amplitude of accommodation, fusional vergence, AC/A ratio, accommodative facility, and vergence facility were performed as binocular tests. Results: NPCs were closest to eyes at high groups. Fusional vergence, AC/A ratio, accommodative facility, and vergence facility of high group showed higher than other groups. The phoria at middle group showed higher than other groups. Conclusions: We found that reading ability and some of binocular functions were closely related. Therefore, vision training, associated with insufficiencies of binocular functions, is expected to improve reading ability.

Objective : The purpose of this study was to provide for the intervention and outcome measurement tools of children with Attention Deficit Hyperactivity Disorder (ADHD) through ICF model. Methods : The systematic review methods were used. Papers published in the journal between January, 2000 and July, 2014 were searched through MEDLINE/PubMed, Sciencedirect, Ovid. The main terms searched were 'ADHD, Children, intervention, outcome measure', and 8 papers were analyzed. Results : 1. The subjects of ADHD were pure ADHD (75.8%), ADHD with dyslexia (9.1%), ADHD with conduct disorder (5.8%), ADHD with tic disorder (3.8%), ADHD with DCD (3.0%), ADHD with emotional disorder (2.5%). 2. The nonpharmacologic intervention of ADHD were functioning and disability (80%) and contextual factors (20%). Most frequently used intervention were body function and structure (60%). 3. The outcome measurement tools of ADHD were functioning and disability (80.5%) and contextual factors (19.5%). Most frequently used outcome measurement tools were body function and structure (70.8%). Conclusion : This study can provide information on the intervention and outcome measurement tools of ADHD.

The present paper reviews experimental finding such as kanji stroop effect, kana superiority effect in naming task, kanji superiority effect in lexical devision task, and the different pattern of facilitatory priming effect in repetition priming task. Most of the experimental findings indicate that kana script and kanji script are processed independently and modularly. These indications are also consistent with the basic observations on Japanese dyslexics. A connectionist model named JIA(Japanese Interactive Activation)is proposed which is a revision of interactive activation model proposed by McClelland & Rumelhart(1981). The differences between the two models are as follows. Firstly, JIA has a kana module and kanji module at letter level. Secondly, JIA adopts script-specific interconnections between letter-level nodes and word-level nodes:word nodes receive larger activation from the script consistent letter-level nodes. JIA successfully explains all the experimental findings and many cases of Japanese dyslexia. A computer program which simulates JIA model was written and run.

Speech and language are uniquely human-specific traits, which contributed to humans becoming the predominant species on earth. Disruptions in the human speech and language function may result in diverse disorders. These include stuttering, aphasia, articulation disorder, spasmodic dysphonia, verbal dyspraxia, dyslexia and specific language impairment. Among these disorders, stuttering is the most common speech disorder characterized by disruptions in the normal flow of speech. Twin, adoption, and family studies have suggested that genetic factors are involved in susceptibility to stuttering. For several decades, multiple genetic studies including linkage analysis were performed to connect causative gene to stuttering, and several genetic studies have revealed the association of specific gene mutation with stuttering. One notable genetic discovery came from the genetic studies in the consanguineous Pakistani families. These studies suggested that mutations in the lysosomal enzyme-targeting pathway genes (GNPTAB, GNPTG and NAPGA) are associated with non-syndromic persistent stuttering. Although these studies have revealed some clues in understanding the genetic causes of stuttering, only a small fraction of patients are affected by these genes. In this study, we summarize recent advances and future challenges in an effort to understand genetic causes underlying stuttering.

With the advance of digital technology, new methods which acquire color information and combine it with various contents are emerging. Color has some effect on emotion while it gives some information as component of an image. In addition, change in emotion and sensation from color stimulus makes some change in cognition. This research investigate the effect of color overlay on cognition depending on emotional state. With this goal, subjects consisting of 10 men and 10 women solved some problems with color overlay of red, orange, and green after watching short video clips which intend to induce target emotion. Experimental results show that red color overlay under positive emotion significantly reduces the average score of solving problems, while green overlay under negative emotion significantly increases it. It is also analyzed that there is not statistically significant difference in cognitive function with color overlay while it is significantly better under positive emotion than negative emotion without color overlay.

The purpose of this study is to suggest design characteristics of picture books for silver generation empirically through academic consideration of necessity and characteristics of picture books targeting silver generation. Through an analytical result of literature materials such as library and information science, pedagogy, and literature therapeutics, and aging phenomenon, picture books help mental and physical health of silver generation, but picture books for silver generation are insufficient in comparison with demand. Therefore, a theoretical basis of study and development of fairy tale books for silver generation is acutely needed. This study suggested that close attention for characteristics of silver generation is needed to solve a problem about dyslexia of silver generation in story, picture(expression, size, layout, structure, and color), and typography of characteristic factors of picture on designing fairy tale books for silver generation, suggesting needs to develop picture books reflecting characteristics such as visual organ, body function, and psychological factor of silver generation. In addition, design characteristics for composition of picture books for silver generation will be used as part of advanced data in a study on solid analytical data through an actual analysis on silver generation in the future.

A film colored overlay has been used as an assistive device for dyslexics, Recently, several virtual colored overlays which can be used in computer were developed. But existing virtual overlays have some drawbacks which have limited colors and limited control capability over overlapped window by the overlays. Limited colors may prevent optimum color selection and limited control capability can obstruct to transfer keyboard and mouse operation to the overlapped window. In this paper, we implemented an overlay function which controls an overlapped window under the overlay window by using keyboard hooking and tray icon. We propose a method to determine the source color of a virtual overlays by estimating alpha value of alpha blending algorithm through measurement of the chromaticity and transmissivity of film overlays and implemented all colors which we can produce colors by using Intuitive Overlays. Test results of the developed virtual overlay show that all mentioned drawbacks of existing virtual overlays were eliminated. Therefore we can employ a result of WRRT to use the developed overlays.

We assessed reading-related skills in children with reading comprehension difficulties ("Poor comprehenders"), word decoding difficulties ("Poor decoders") and normal readers, matched for age and nonverbal IQ. The reading-related skill tests used in our study are phonological processing, visual processing test, and receptive vocabulary test. The authors argue that children who had difficulty in reading comprehension had lower scores only on the phonological short-term memory test compared with normal readers, although their performance on receptive vocabulary and visual processing tests are comparable to normal readers. The results of our study revealed that poor decoders had lower scores on the phonological processing, visual processing, and receptive vocabulary tests.
