Purpose: This study was conducted in order to evaluate how chemiluminescent lighting($ViziLite^{(R)}$) could increase the sharpness of margin and contrast to normal mucosa in the diagnosis of oral lichen planus(OLP), the most frequent oral premalignant lesion, compared with direct visual inspection under incandescent light. Methods: 41 consecutive patients, diagnosed to have OLP with visual inspection under incandescent light, were further examined with chemiluminescent light. The degrees of margin sharpness and lesion contrast were ranked on a scale from 1 to 3 for all patients under visual inspection and chemiluminescent light. The presence of additional lesion only detected by chemiluminescent light, complication, and discomfort were checked for each patient. After both screening tests, biopsy specimens were harvested from all patients with scalpels and histopathologic assessments were done. Results: All 41 patients were diagnosed to have OLP by both visual inspection and chemiluminescent light examination. This result was definitively diagnosed by histopathology. Degrees of margin sharpness and lesion contrast were increased by chemiluminescent light compared with visual inspection, but only the difference of lesion contrast was statistically significant. In 22.0% of patients, additional lesions were detected and 88.9% of them were diagnosed to have OLP histopathologically. 17.1% of patients noted discomfort and 9.8% of patients showed complications after chemiluminescent test. Conclusion: Chemiluminescent light may not be proper for the screen test of oral cancer or premalignant lesion but showed some possibility for additional diagnostic tool for definitively diagnosed patients in determination of lesion margin and scope.

Purpose: The purpose of this study was to identify changes in the experience rate and level of symptoms of visual display terminal syndrome in college students attending online classes during the COVID-19 pandemic. Methods: Data were collected from February 22 to June 8, 2021 at three measurement points. A total of 117 college students were administered a visual display terminal syndrome survey just before online classes (T1), one month after the start of online classes (T2), and three months after the start of online classes (T3). The collected data were analyzed by frequency and percentage, paired t-test, McNemar test, and repeated measures analysis of variance using the IBM SPSS 25.0 program. Results: The intensity of college students' visual display terminal syndrome during online classes increased at T2 and T3 compared to T1. The rate of experiencing back discomfort or pain increased abruptly at T2 compared to T1. The intensity of college students' eye related symptoms and skin related symptoms increased at T2 and T3 compared to T1, while the intensity of college students' psychological symptoms, general body discomfort, and musculoskeletal symptoms increased at T3 compared to T1. Conclusion: The results of this study suggest that self-care programs are needed to prevent visual display terminal syndrome in college students who are in long-term online classes.

Daylighting is the controlled admission of natural light into a space, reducing electric lighting and saving energy. By providing a direct link to the dynamic and perpetually evolving patterns of outdoor illumination, daylighting helps create a visually stimulating and comfort environment for building occupants, while reducing energy costs. Especially, however, glare is the most important factor in daylighting, which is issued by incoming direct sunlight into windows. This study analyzed the discomfort glare on a daylighting window by using Image processing methodology and found a solution to problems with glare source of occupants. There are several ways to evaluate discomfort glare such as UGR (Unified Glare Rating) of CIE, DGI (Daylight Glare Index, Hopkinson, 1972) and VCP (Visual Comfort Probability) of IES. These are used to apply to the relatively little artificial light source and they cannot cover discomfort glare from a real daylighting window. In this regarding, this paper aimed to calculate DGI index of the real daylighting window in a experimental space by using image processing methodology. The variables and outcomes are luminance distribution of non-shading window, effect of venetian blind installed on the window and locations related to position index of DGI.

The purpose of this study was to test whether adhesive taping therapy, one of rehabilitation, helps to relieve chronic low back pain. Sample were selected from 35 outpatients at oriental medicine hospital in the period from April 20 to June 20, 1998. The research design was one-group pretest - posttest design. The pretest included measuring discomfort depending on the scope and types of a range of motion, and their pain by their activity of daily living(ADL). In this research design, a treatment was to expose adhesive taping therapy to samples. The posttest included remeasuring of their discomfort and pain by ADL. The results of this study was as follows: Hypothesis I was that the discomfort score of the post-treatment group had lower than does that of the pre-treatment group. This study accepted the hypothesis (t=2.70, p=.015). Hypothesis II was that the post-treatment group had the pain score by ADL lower than does the pre-treatment group. Empirical results showed statistical significance(t=4.53, p=.000). In summary, the effect measured by the discomfort with a visual analog scale was statistically significant. The degree of pain according to postures in ADL also showed statistical significance. Consequently, these findings showed that the adhesive taping therapy was effective to alleviation of chronic low back pain.

This paper suggests the best work conditions, including short break time and number of mouse clicks on a computer, to prevent MSDs(Musculoskeletal Disorders) on VDT(Visual Display Terminal) work. Discomfort measures are calculated according to the Borg's CR-10 Scale. The short break time conditions are grouped into 7, 15, and 30 seconds after every 10-minute work period and the number of mouse clicks are divided into 10 clicks/min, 20clicks/min, and 30clicks/min. The result of the ANOVA on the shift value of subjective discomfort shows the following: 1) Regarding the break time and the number of mouse clicks, there are statistical differences between the measured values for the neck and the wrist(p<0.05). 2) Regarding the number of mouse clicks, there are statistical differences between the measured values for the shoulder and the forearm(p<0.1). 3) Regarding the break time and the number of mouse clicks, there are no statistical differences between the measures values for the eyes, upper arms and back(p<0.1).

자연채광은 건물 재실자에게 시각적 편안함과 쾌적함을 제공하여 건강성을 향상시키며 조명 에너지를 절약할 수 있는 중요한 조명환경 요소이다. 자연광에 의해 발생되는 창면에서의 글레어는 장시간 노출될 시 시각의 저하, 시각적 불쾌감의 원인이 된다. 창면에 의한 불쾌글레어 평가시에는 창면에서 글레어 광원을 어떻게 선별할 것인가가 중요한 문제이다. 기존의 불쾌글레어 평가법을 적용하더라도 글레어 광원을 한정할 방법이 없다. 따라서 본 연구에서는 글레어 광원 선별방법을 모색하기 위하여 불균일한 대광원의 휘도차가 불쾌글레어감에 미치는 영향을 검토하였다. 이를 위하여 $120{\times}120[cm]$의 정사각형 모형창을 제작하였다. 실험변수는 균일과 불균일한 휘도분포의 광원의 휘도비와 광원크기로 선정하였다. 실험방법은 모형창을 3분할한 후, 각기 다른 휘도비를 설정하여, 1[m], 1.5[m], 3[m] 거리에서 불쾌글레어를 평가하도록 하였다. 실험 결과 두 개의 결론을 얻었다. 첫째, 광원의 평균휘도가 증가할수록 불쾌글레어 평가값이 증가하였으며, 둘째, 창면 상부의 천공 부분만을 글레어 광원으로 볼 수 없으며 하부면도 블쾌글레어 평가에 영향을 주는 것으로 나타났다. 본 연구의 결과는 채광창으로부터의 불쾌글레어 평가 시 글레어 광원을 선택하는 기준으로 활용될 수 있을 것이다.

Background: It is well known that nasotracheal intubation is comfort for patient compared to oral intubation. We sometimes delay extubation when it is thought that the patient can not maintain airway, or there may be other emergency associated with airway. And we sometimes experience complaint of discomfort of nasotracheal tube. But, we could not find any report on degree of discomfort of delayed nasotracheal intubation. Methods: Eighteen patients in whom extubation of nasotraceal tube was delayed after operation because of difficulties of airway mamagement were selected. We surveyed the discomfort of nasotracheal tube with 0 to 10 visual analogue scale (VAS) and compared with the pain of operation site (VAS). Result: The VAS of nasotracheal intubation was $6.7{\pm}3.4$, and VAS of the primary operation site was $3.5{\pm}2.4$, and VAS of flap harvest site was $5.5{\pm}2.7$. 10 of the patients complained of nasotracheal suction extremely and 6 patients complained of respiratory difficulties. Conclusions: Nasotracheal intubation was discomfort and there must be intervention.
