A case of chronic dry cough which was tried to be treated through so many medications in a period of two months, responded very well to a simple ayurvedic remedy composing of a common formulation chosen as per the ayurvedic principles of pathogenesis and management. This case may be an eye opener to the concurrent ayurvedic clinical practice and invites ayurvedic practitioners to stick to their own principles of disease management for obtaining better responses.

In recent years, and with the increased adoption of digital transformation and spending long hours in front of these devices, clinicians have observed that the prolonged use of visual display units (VDUs) can result in a certain symptom complex, which has been defined as computer vision syndrome (CVS). This syndrome has been affected by many causes, such as light refractive errors, poor computer design, workplace ergonomics, and a highly demanding visual task. This research focuses on eliminating one of CVSs, which is the eye dry syndrome caused by infrequent eye blink rate while using a smart device for a long time. This research attempt to find a limitation on the current tools. In addition, exploring the other use cases to utilize the solution based on each vertical and needs.

This study aimed to identify the prevalence of dry eye, sleep disorder, depression and factors related to dry eye among the elderly living in the community. Study subjects were 149 elderly, 65 years of age or older from nearby people, acquaintances and community elderly-related centers that researchers could access. Data collection period was from June 1 to August 31, 2021. Data were analyzed by frequency, percentage, mean, standard deviation, ANOVA, χ²-test, and multiple logistic regression. The results showed that dry eyes in elderly people were statistically significant according to age (χ²=4.50, p=.034), occupation (χ²=7.14, p=.008), chronic diseases (χ²=6.59, p=.010), drugs (χ²=4.86, p=.027), eye surgery (χ²=6.02, p=.014), and sleep disorders (χ²=7.29, p=.007). Multiple logistic regression revealed that dry eyes were associated with sleep disorders (OR=2.45, 95% CI=1.17-5.13). Therefore, for the management and prevention of dry eyes in the elderly, there is a need for nursing intervention and strategy that can find the causes of sleep disorders and improve the quality of sleep.

Through this, we hope that the development of our diagnosis and treatment. Methods : From June 1, 2010 to May 31, 2019, Based on the electronic medical records of patients who had funduscopy examination at Korean Medicine Ophthalmology, Busan University Korean Medicine Hospital, the gender, age, visiting motives and paths, diagnosis, examination number of years, other eye examinations and treatments method were summarized and analyzed. Results : 463 patients were able to check the electronic medical records. They were 283 females and 180 males. The mean age of the patients was 51.5 years and elderly patients who 50s and 60s were 49.3% of whole patients. The most common motives for Korean Medicine Ophthalmology visitation was 'combination treatment with other department in Korean Medicine Hospital'. Outer eye diseases were 283 cases, inner eye diseases were 198 cases. Dry eye syndrome, asthenopia, visual discomfort, conjunctivitis, and eye discomfort were most common in the outer eye diseases. Cataracts, Vitreous floater, Macular Degeneration, Glaucoma and Ocular Pain were most common in the inner eye disease. The most common parts of outer eye diseases were Conjunctival, lacrimal gland, paralytic, corneal, eyelid and front uveal, scleral disease and then in inner eye diseases parts, Retinal, lens, vitreous, glaucoma, optic nerve, behind uveal, choroid disease were most common. The number of funduscopy examination was ups and downs. Herbal medicine was the most common used. Conclusions : The funduscopy examination is essential for diagnosis and treatment of eye disease. We hope that the use of fundus examination and other ophthalmologic examination will be expanded soon in Korean Medicine Ophthalmology.

Leaf area index (LAI) is important in explaining the ability of crops to intercept solar energy for biomass production, amount of plant transpiration, and in understanding the impact of crop management practices on crop growth. This paper describes a procedure for estimating LAI as a function of image-derived vegetation indices from temporal series of RapidEye imagery obtained from 2010 to 2012 using empirical models in a rice plain in Seosan, Chungcheongnam-do. Rice plants were sampled every two weeks to investigate LAI, fresh and dry biomass from late May to early October. RapidEye images were taken from June to September every year and corrected geometrically and atmospherically to calculate normalized difference vegetation index (NDVI). Linear, exponential, and expolinear models were developed to relate temporal satellite NDVIs to measured LAI. The expolinear model provided more accurate results to predict LAI than linear or exponential models based on root mean square error. The LAI distribution was in strong agreement with the field measurements in terms of geographical variation and relative numerical values when RapidEye imagery was applied to expolinear model. The spatial trend of LAI corresponded with the variation in the vegetation growth condition.

Purpose. The purpose of this study was to investigate the effect of changes in tear break-up time, accommodative response amount, and accommodative microwave on the eyes due to changes in humidity. Methods. A total of 48 adult men and women in their 20s (21.1±1.56 years old) were surveyed on dry eye questionnaires (OSID questionnaires), tear destruction time was measured by humidity (40%, 60%, 80%), and controlled reactions and controlled fine waves were measured through tactile tests. Result. As a result of the OSID questionnaire, there were 10 normal patients, 8 mild dry eyes, 1 moderate dry eye, and 5 severe dry eyes. The initial tear film destruction time was 7.34±4.67 seconds at 40% humidity, 8.99±4.75 seconds at 60% humidity, 10.26±4.52 seconds at 80% humidity, and the average tear film destruction time was 9.51±4.07 seconds at 40% humidity, 10.99±3.82 seconds at 60% humidity, and 12.05±3.42 seconds at 80% humidity. The accommodative response was -0.41~1.79D at 40% humidity, -0.34~1.79D at 60% humidity, and -0.30~2.01D at 80% humidity. The accommodative microwave was measured as 56.39~63.43dB when it was 40%, 56.41~62.64dB when it was 60%, and 55.96 ~61.13dB when it was 80%. Conclusion. As the humidity (40~80%) increased, the tear break-up time increased, and as the accommodative stimulus amount increased, the accommodative response amount increased. It was found that the accommodative microwave according to the amount of accommodative stimulation increased, and as the humidity increased, the accommodative microwave decreased.

Purpose: The study was performed to compare the differences in lens rotation, lens movement by blinking and lens centration with alignment or steep fitting of soft contact lens in normal and dry eyes. Methods: Total 40 eyes (aged 20~30 years) were classified into the normal (n=20) or dry eye group (n=20) by the diagnosis methods for dry eyes and worn soft contact lens (polymacon material) with alignment fitting or steep fitting. Lens rotation, lens movement by blinking and lens centration were separately measured immediately after lens wearing and after stabilization of tear film and compared by fitting states of soft contact lenses. Results: With steep fitting of soft contact lens in dry eyes, averaged lens rotation immediately after lens wearing was not significantly different from that of the normal eye group with alignment fitting however, lens rotation after stabilization in dry eyes was significantly larger than that in normal eyes. Any significant difference in lens movement by blinking was not shown in normal eyes. However, lens movement by blinking in dry eyes was increased with steep fitting. The range of lens centration on cornea in normal eyes with alignment fitting was more vertically distributed. On the other hand, the range of lens centration on cornea in dry eyes with alignment fitting was more horizontally distributed. Lens centration was shown to be changed by stabilization of tear film. That is, lens centrations were somewhat vertically widespread immediately after lens wearing and restrictively distributed in horizontal direction, respectively, with steep fitting in dry eyes. Conclusions: These results suggested that lens movements and centration in dry eyes were different from those of normal eyes. Especially, those differences between normal and dry eyes were much bigger with steep fitting of soft contact lenses. Thus, those differences should be considered for the comfortable and safe fitting of soft contact lens in dry eyes.

Objective : Acupuncture has been used for treating eye disease for thousands of years but there are few evidence based medicine (EBM) for its use. This study is a review of Clinical trials related to the treatment of eye disease by acupuncture therapy. Methods : We referred a Pubmed site by using searching word of "eye, acupuncture" (Limits: 10 Year, Clinical Trials, Humans, English). Results : Eight journals with twelve papers were searched. Eight of these studies were randomized and ten trials of acupuncture treatments reported significant effect. On the topic of these clinical trials, five of them were about dry eyes, four about disorder of refraction, two about intraocular pressure and one about visual function. The result of clinical studies represented the significant cure rate. Conclusion : We found that RCTs about the acupucnture for eye diseases were more and more published. But their average impact factor was 2.16 and average modified Jadad score was 3.89, so there needs more qualifying studies.
