In this study, literature review was done to examine and compare the current status and problems of different evaluation approaches toward permanent impairment in Korea. Alternatives and improvements in the current approaches in Korea were suggested. Series of cases were also examined to compare different approaches applied to the real cases, using 105 cases from a hospital data and another 207 cases from a insurance company data. The main findings of the literature review are as follows; 1. The current evaluation methods of permanent impairment in Korea are grouped into two categories, grading and rating. Gradings of impairments are expressly specified in 17 various statutes. 2. In Grading methods, the rigid system of 74 different grades has been adopted uniformally for the convenience of administration, which may not be, appropriate or valid from medical and scientifical aspect. 3. The adventage of McBride method is assessment of occupational disability rate. However the classified compensable occupations are only 280 and limited to manufacturing industries in 1960s'of U.S.A., which is not appropriate to current Korean circumstances. Especially, the job list does not include managerial officers or mental workers. 4. AMA Guides is the scientific and reasonable method for the assessment of physical impairment rate. However compensation and reparation of impairment case is difficult because this method cannot assess the disability rate according to occupation, age, etc. The results of cases comparative study are as follows: 5. The physical Impairment could be compared in 167 out of total 312 cases, and for the cases of complex impairment, McBride method underestimate physical impairment rate compared with AM A method. 6. When disability late was assessed, occupation was considered the compensation of only 85 cases, and age was used in only 21 cases. This was because occupation and age compensation in McBride method are unreasonable. 7. The most Ideal alternative is to assess physical impairment according to AMA method and then to develop a compensation method appropriate for the circumstances of Korea society.

Diabetic retinopathy (DR) is a prevalent complication of diabetes that can lead to vision impairment if not diagnosed and treated promptly. This study presents a novel approach for the automated grading of diabetic retinopathy in ultra-widefield fundus images (UFI) using deep learning techniques. We propose a method that involves preprocessing UFIs by cropping the central region to focus on the most relevant information. Subsequently, we employ state-of-the-art deep learning models, including ResNet50, EfficientNetB3, and Xception, to perform DR grade classification. Our extensive experiments reveal that Xception outperforms the other models in terms of classification accuracy, sensitivity, and specificity. his research contributes to the development of automated tools that can assist healthcare professionals in early DR detection and management, thereby reducing the risk of vision loss among diabetic patients.

본 연구의 목적은 청각장애인이 경험하는 위험상황과 청각 대체기술로 사용하는 보조기기 사용실태를 조사하여 청각증강 기술 개발의 적용점을 모색하는 데 있다. 이를 위해 청각장애 등급을 판정받은 청각장애인을 대상으로 설문조사하여 총 355명의 자료를 분석에 사용하였다. 연구결과 첫째, 소리 및 진동을 인지한 경험이 없는 상황으로 교통수단, 사물, 자연 영역 순으로 높게 나타났다. 이 중 교통수단의 소리와 진동을 인지하지 못한 비율이 높아 일상생활에서 청각장애인이 경험하는 위험 가능성이 높은 것으로 조사되었다. 둘째, 청각장애인이 경험한 위험상황은 교통사고, 보행사고, 가정에서의 일상생활 순으로 높게 조사되었다. 셋째, 위험상황 인식과 알림을 위한 보조기기로 2G폰/스마트폰, 진동디지털알람시계, 경광등, 진동손목시계의 인지도가 높았으며, 2G폰/스마트폰의 만족도가 가장 높았다. 넷째, 의사소통을 위한 보조기기로 보청기, 스마트폰, 영상전화기, 인공와우, 2G폰 순으로 인지도가 높았으며, 스마트폰을 사용하였을 경우 만족도와 의사소통 개선정도가 가장 높게 조사되었다. 마지막으로 청각증강 기술 개발을 위해 고려할 점으로 휴대/착용 편의성, 가격, 동작 정확도 순으로 선호하였으며, 알림 전달 방식은 시각(문자와 빛)을 활용한 알림방식을 선호하였다. 연구결과에 근거하여 위험상황에서 청각장애인의 청각증강 기술 개발을 위한 정책적, 실천적 방안을 제시하였다.

This study aimed to compare movement patterns of shoulder joints between the right and left symmetry in stroke patients and control subjects. This study proposes use of the voluntary response index (VRI) calculated from quantitative analysis of surface electromyographic (sEMG) and motion data recorded during voluntary movement as a feeding task. The VRI is comprised of two numeric values, one derived from the total muscle activity recorded for the voluntary motor task (magnitude), and the other from the sEMG distribution across the recorded muscles with the similarity index (SI). Five stroke patients and five age-matched healthy controls were recruited. Feeding motion was performed using the provided spoon five times with rests taken on a chair in between tasks. EMG data were digitized and analyzed on the basis of the root mean square (RMS) envelope of activity. The average amplitude of responses was calculated. Responsiveness and clinically meaningful levels of discrimination between stroke patients and control for EMG magnitude and SI were determined. The similarity index of the results from two successive examinations of both sides apart for stroke patients and control subjects were .86 and .95 in motion analysis and .84 and .99 in electromyographic analysis. The SI of sEMG data and motion data was significantly correlated in stroke patients. The data suggest that SI is a sensitive program for comparing and analyzing the symmetry of muscle activity and motion in both sides. This analysis method has a clinical value in grading muscular activity and movement impairment after brain injury.
