Reliability of a Tablet Computer-Based Dyslexia Screening Application Using an Eye-Tracking System
Segeun Park,Jonggeun Song,엄태훈,김영훈 대한소아신경학회 2024 대한소아신경학회지 Vol.32 No.2
Purpose: The early detection and management of dyslexia are crucial for preventing irreversible educational gaps and various negative consequences for affected students. However, diagnosing dyslexia is challenging because it requires a comprehensive assessment. Dyslexia screening tests that utilize fast, automated, computer-based technology can be useful for early identification and management. In this paper, we introduce a tablet computer-based dyslexia screening application that uses an eye-tracking system and verify its reliability. Methods: The study included 200 participants between 8 and 13 years of age from an elementary school, all of whom underwent dyslexia screening tests twice. The screening was conducted using the VisualCamp SeeSo eye-tracking Android Software Development Kit v3.0.0, implemented on Samsung Galaxy Tab S5e tablets. The eye-tracking system measured reading speed by gaze, mean gaze fixation time, gaze fixation frequency, saccadic length, and regression ratio. To assess the reliability of the two sets of measurements, the intraclass correlation coefficient (ICC) was employed. Results: Excellent reliability was found for measurements of gaze fixation frequency (ICC=0.83), gaze fixation mean time (ICC=0.82), and reading speed by gaze (ICC=0.76), and good reliability for measurements of regression ratio (ICC=0.75) and saccadic length (ICC=0.72). Conclusion: This study demonstrated that the tablet computer-based dyslexia screening application reliably measured eye movements in subjects with dyslexia. Furthermore, the application proved to be highly reliable and potentially suitable for use in clinical or school settings, eliminating the need for a laboratory environment and extensive equipment.

외부압력으로 부착된 강판으로 보강된 구속콘크리트의 압축반복거동 모델
최은수,송세근,Choi. Eunsoo,Song. Segeun 한국방재학회 2013 한국방재학회논문집 Vol.13 No.1
본 연구에서는 그라우팅 없이 외부압력을 이용해서 부착된 강판으로 보강된 콘크리트의 압축반복거동에 대한 응력-변형률 모델을 개발하여 제공하고자 한다. 두께 1.0 mm와 1.5 mm 두 종류의 스테인레스 스틸로 <TEX>$150mm{\times}300mm$</TEX> (<TEX>${\Phi}xH$</TEX>)의 시편을 보강하였다. 압축강도가 1.0 mm 및 1.5 mm 두께에 대해서 각각 강도 증가율이 32.1% 및 45.6% 으로 나타났으며 Sakai and Kawashima 모델을 이용하여 구속 효과를 확인하기 위해 보강된 콘크리트 기둥의 반복하중 거동을 분석하였다. 본 연구 실험의 반복하중 거동을 Sakai and Kawashima 모델과 비교 분석해 본 결과, 제하 이력곡선과 재재하 이력곡선이 값의 재해석을 통해 매우 일치함을 확인할 수 있었다. This study provides a model for cyclic compressive behavior of concrete confined by steel wrapping jackets without grouting. This study uses concrete specimens of <TEX>$150mm{\times}300mm$</TEX> (<TEX>${\Phi}xH$</TEX>) with steel jackets of the thickness of 1.0 mm and 1.5 mm. The peak strength of concrete increases by 32.1% and 45.6% with applying the steel jacket of 1.0 mm and 1.5 mm, respectively. This study adopts the Sakai and Kawashima model for cyclic compressive behavior of confined concrete, and it is found that the experimental results correspond well to the adopted model.
