안구 건조증 예방을 위한 AI 기반 생활습관 개선 시스템 연구
성민규(Min-kyu Seong),송기원(Ki-won Song) 한국정보기술학회 2022 Proceedings of KIIT Conference Vol.2022 No.12
현대인들의 전자기기 사용량이 많아짐에 따라 잘못된 눈 건강 생활습관으로 인해 안구 건조증을 호소하는 사람들이 증가하는데, 안구 건조증은 눈 깜빡임의 적은 빈도수로 인한 눈물막 파괴가 주요 원인이다. 본 논문은 이미지 분석에 특화된 CNN(Convolutional) 딥러닝 모델을 활용하여 사용자의 눈 깜빡임을 인지하여 기록하고 생활습관 개선에 도움을 주는 시스템을 설계 구현한 내용을 기술한다. 본 시스템은 실시간으로 눈 깜빡임을 인지하고 10초 이내에 눈 깜빡임이 없을 시 알람을 주어 잘못된 생활습관을 확인하고 바른 생활습관을 유도하도록 하는 것이 목적이며 실시간으로 눈 깜빡이는 생활습관을 데이터 표와 그래프를 통해 확인하여 안구 건조증 예방에 도움을 준다. As modern people use electronic devices, more and more people complain of dry eyes due to poor eye health lifestyle, which is mainly due to the small frequency of blinking. This paper describes the design and implementation of a system that recognizes, records, and helps improve lifestyle by using CNN (Convolutional) deep learning models specialized in image analysis. The purpose of this system is to recognize blinking in real time and to give an alarm if there is no blinking within 10 seconds to check the wrong lifestyle and induce the right lifestyle. In addition, it helps prevent dry eye syndrome by checking the blinking lifestyle in real time through data tables and graphs.

Purpose: We aimed to analyze the effect of fixation tightness of the syndesmotic screw and its indwelling period on the recurrence of the syndesmosis widening after screw removal and the clinical outcomes. Materials and Methods: Forty consecutive patients with acute syndesmotic injury were retrospectively reviewed. The tibiofibular clear space is measured by digitalized measurement tool on serial radiographs. We analyzed the effect of time from trauma to fixation, syndesmotic screw indwelling duration, and fixation methods. Residual symptoms at the last follow up were evaluated. The student t-test, correlation test, and chi-square test were used for statistical analysis. Results: Eighteen ankles (45%) had recurrent syndesmosis widening (greater than 5% compared to the contralateral side). Seven patients had pain and five had limitation of motion in the ankle joint. Fixation tightness had significant effect on reducing the recurrence while the severity of the initial widening, time to fixation, and duration of fixation did not affect the outcome. Conclusion: Tight fixation of syndesmotic screw is essential for achieving final syndesmotic stability and reducing recurrence.
