목적: 중심장액성맥락망막병증을 가진 눈의 망막 두께 및 망막 부피와 같은 망막 상태와 시력과의 상관관계를 알아보았다. 방법: 총 78명 136안을 대상으로 중심장액성맥락망막병증을 치료 중인 눈 및 무증상 반대편 눈, 중심장액성맥락망막병증을 진단받은 후 완치된 눈 및 반대편 눈과 정상인 눈 각각의 나안시력, 최대교정시력, 망막 두께, 망막 부피를 측정하였다. 결과: 중심장액성맥락망막병증을 치료 중인 눈은 나안시력, 최대교정시력, 망막 두께, 망막 부피 모두에서 반대편 무증상 눈, 질환이 완치된 눈 및 정상 눈과 비교하여 통계적으로 유의하게 차이가 있었다. 중심장액성맥락망막병증의 반대편 무증상 눈의 최대교정시력은 정상 눈과 차이가 없었으나 망막 두께 및 망막 부피는 정상 눈과 통계적으로 유의한 차이가 있었다. 망막 두께가 증가함에 따라 망막 부피가 증가하는 정도가 정상안의 경우보다 중심장액성맥락망막병증 소견을 보이는 눈이나 반대편 무증상 눈, 중심장액성맥락망막병증이 완치된 눈 및 그 반대편 눈에서 더 컸다. 결론: 본 연구를 통하여 중심장액성맥락망막병증을 가지고 있는 눈 뿐만 아니라 반대편 무증상 눈에서도 망막 두께 및 망막 부피가 증가하며, 중심장액성맥락망막병증에 의한 최대교정시력의 변화는 일정 정도 이상의 망막 두께 및 망막 부피가 증가되었을 때 나타남을 밝혔다.

The purpose of this study was to examine the need of the eyelash design area and the changes of an eye image according to eyelash design. Methodology included both a theoretical research and an empirical research. The theoretical research reviewed previous researches and technical books. The empirical research divided eye shapes, complemented the defect of eye shapes, and examined resulting image changes. A mechanical way was performed for treatment because it was more efficient than a manual way. A J-curl type was used. Eye length was divided into five and the point was determined. The length and density of curl were changed in each point to maximize a treatment effect. As a result, eye images were changed as follows. First, round eyes became stable. Slit eyes became vivid and soft. Wide-set eyes became intelligent and narrow-set eyes became smooth. Large eyes were naturally gradated and small eyes became larger. Double-eyelid eyes became stable and elegant and single-eyelid eyes became gentle and soft. Bulging eyes became easy and soft and sunken eyes became smooth. Peaked eyes became gentle and soft and sleepy eyes became strong and vivid. Based on the findings, eyelash design can play a role in changing an image according to eye shapes. In particular, a speed eyelash extension device to extend eyelash can reduce working hours and gradate only by angle control. It can complement the defect of eyes according to the design of each shape and change into a better image.

The purpose of this study to evaluate and compare the proprioception of the dominant knee joint at different conditions in normal 20 years of age. The pripriocption was measured at sitting, supine, prone position with the eyes opened and the eyes closed. All were assessed with and without a knee brace around the knee by reproduction the position to which a joint has previously been placed. In this study, 24 rehabilitation therapy major students were assessed at Hansoe University. In this study applied the paired t-test and 1-way ANOVA to determine the statistical significance of results at 0.05 level of significance. The error average of proprioception was $4.65{\pm}2.95^{\circ}$ with the eyes closed and $4.08{\pm}1.14^{\circ}$ with the eyes opened in sitting position, $5.56{\pm}3.18^{\circ}$ with the eyes closed and $4.98{\pm}2.99^{\circ}$ with the eyes opened in supine position and $5.60{\pm}1.64^{\circ}$ with the eyes closed and $4.87{\pm}2.16^{\circ}$ with the eyes opened in prone position. There was no significantly difference the error average between the eyes opened group and the eyes closed group. There was no significantly difference the error average among the three positions. The error average decreased significantly in knee brace group at all conditions.

Objectives Eyes, one of visual inspection regions, present important clues to pathological patterns including deficiency and excess patterns to the clinicians. The purpose of this study was to develop Eyes Inspection Questionnaire (EIQ) and to examine which items among the EIQ were more predictive of clinicians' determination for the deficiency and excess patterns. Methods Nine questionnaire items for Visual Inspection of Eyes were extracted through the literature review. These items were presented to the 4 Korean medical doctors who are specialized in visual inspection to conduct the Delphi method. The Korean medical doctors were asked to rate the importance of each items for the corresponding Visual Inspection of Eyes, using a Likert 5-point scale(the 3 points of importance as a cut-off point). Then, out of 75 photographs submitted to the Society of HyungSang Medicine in 2009, 30 portrait pictures were selected as samples. The samples were copied to make 60 sample pictures, and then randomly assigned to 4 clinicians. The 4 clinicians evaluated the 60 samples for excess and deficiency of the eyes and were asked to check the 6 questionnaire items. The results were recorded as 5-points-scale, and their average and standard deviations were calculated. Intra- class reliability test and multi regression test were performed using SPSS 13. Results Intra-class correlation coefficient (ICC) was between 0.750 to 0.841 (P<0.05). Indices for visual inspection of the eyes were: endowment of the bone structure around the eyes; brightness of the eyes; upward deviation of the eyes; eye shapes; and definition of iris. 76.92% of deficiency symptom patterns and 86.42% of the excess symptom patterns matched the patterns predicted by the visual inspection of the eyes, according to the frequency analysis. According to the multiple regression analysis, were significantly related to the excessive symptoms, and to the deficiency symptoms. Conclusion This study is the first attempt of development for checklist of excess and deficiency of Visual Inspection of Eyes and quantitative measurement of excess and deficiency using the Visual Inspection of Eyes by the visual inspection experts. Still, additional studies are needed regarding the relationship visual inspection methods have with existing standards of diagnosis.

본 논문은 얼굴에서 왼쪽 눈, 오른쪽 눈, 입, 코의 위치를 검출하고 POSIT(Pose from Orthography and Scaling with ITterations) 알고리즘을 이용하여 3차원 객체의 위치와 방향을 알아내는 방법을 제안한다. 왼쪽, 오른쪽 눈을 검출하는 단계에서는 사람의 얼굴에서 눈이 가지는 위상학적 특징과 형태학적 특징을 이용한다. 위상학적 특징을 기반으로 눈의 대략적인 위치를 구하고 형태학적인 특징을 이용하여 눈동자를 검출한다. 4개의 특징점 검출 후 POSTIT를 이용하여 얼굴의 회전 정도를 찾아 눈의 시선 방향을 찾았다.

This study aimed to evaluate the surface area and velocity of center of pressure (COP) during one leg standing by stimulating the sensory system in normal adults. Thirty subjects were enrolled in this study. Subjects were asked to stand on one leg during testing conditions. Testing conditions included 6 different sensory stimulations as follows: eyes opened, eyes closed, eyes opened with vibrator, eyes opened with head-mounted display (HMD), eyes opened with vibrator and HMD, and eyes closed with vibrator. During each testing condition, the surface area and velocity of center of pressure were measured. There were significant differences in the mean surface area and the mean velocity of COP between the "eyes opened" condition and the other five testing conditions (p<.05). However, in the comparison between the "eyes closed" and "eyes opened with HMD" conditions, there were no significant differences in the tested parameters. This study shows that closing eyes or keeping eyes opened while using HMD to experience virtual reality has the same effect on one leg standing balance. This finding should be considered in the evaluation or intervention of balance, especially one leg standing balance and balance while standing with a small base of support.

Nowadays, eyes detection is required and considered as the most important step in several applications, such as eye tracking, face identification and recognition, facial expression analysis and iris detection. This paper presents the eyes detection in facial images using Harris corner detection. Firstly, Haar-like features for face detection is used to detect a face region in an image. To separate the region of the eyes from a whole face region, the projection function is applied in this paper. At the last step, Harris corner detection is used to detect the eyes location. In experimental results, the eyes location on both grayscale and color facial images were detected accurately and effectively.
