  • In this study, five cases of post-stroke vision disorders are presented. The patients had no distinctive change in vision disorders before Korean medical treatment, which included herbal medicine, acupuncture, and electroacupuncture. After 11 to 28 days of Korean medical treatment, the patients experienced the first improvement of vision disorders after stroke. Also, patients who received Korean medical treatment after 30 days from onset, the duration in which the most improvement of post-stroke vision disorders occurs, progressed their vision disorders by the start of Korean medical treatment. Korean medical treatment might be effective in treating vision disorders after stroke.

  • Machine vision system was used for analyzing leaf color disorders of tomato plants in a greenhouse. From the day when a few leave of tomato plants had started to wither, a series of images were captured by 4 times during 14 days. Among several color image spaces, Saturation frame in HSI color space was adequate to eliminate a background and Hue frame was good to detect infected disease area and tomato fruits. The processed image ($G{\sqcup}b^*$ image) by OR operation between G frame in RGB color space and $b^*$ frame in $La^*b^*$ color space was useful for image segmentation of a plant canopy area. This study calculated a ratio of the infected area to the plant canopy and manually analyzed leaf color disorders through an image segmentation for Hue frame of a tomato plant image. For automatically analyzing plant leave disease, this study selected twenty-seven color patches on the calibration bars as the corresponding to leaf color disorders. These selected color patches could represent 97% of the infected area analyzed by the manual method. Using only ten color patches among twenty-seven ones could represent over 85% of the infected area. This paper showed a proposed machine vision system may be effective for evaluating various leaf color disorders of plants growing in a greenhouse.

  • This study was conducted to find out effect of dynamic balance performance in normal adult when obscuring vision in half of the both eye and to prepare the basic data treatment of brain damage patient with visual field deficit. The subject for this study included 40 healthy right-handed and 20 left-handed were dynamic balance performance when obscuring vision in half of the both eye. who age from 20 to 30 years in normal adult without neurosurgical orthopedic, performance balance disability or other medical disorders. Of these individuals 20 right-handed and 20 left-handed were executed dynamic balance performance when obscuring vision in half of the both eye. individuals of right, left-handed were executed dynamic performance when obscuring vision in half of the both eye measure with a Balance Performance Monitor (BPM) Data print Software Version 5.3. In other to determine the statitsical significance of the result, instrumentation was used to t-test, chisquare of the SAS(Strategic Application Software) The result of the study were that: 1) Significant differences in LOS were found right-handed and left-handed subject when dynamic performance without obscuring vision and obscuring vision(p<0.05). 2) Significant differences in LOS were founded left-handed when dynamic performance were executed obscuring vision and without obscuring vision(p<0.05). 3) Significant differences in LOS were founded right-handed when dynamic performance were executed obscuring vision and without obscuring vision(p<0.05).

  • Among five sense organs or Gyanendriyas 'Eyes' are considered as most important sense organs. They are said to be the path to mind and seat of Tejas (Light). Now a days due to their overuse and negligence in maintenance we are facing many eye related problems like Dry Eye Syndrome, Cataract, Age related Macular Degeneration, Glaucoma, Computer Vision Syndrome etc. To observe the association of defective lifestyle and related eye problems with their preventive measures, different Ayurvedic procedures are reviewed from ancient literatures and some modern researches. Dinacharya (Daily regimen) explained in Ayurveda helps to prevent many derangements. Lifestyle modification in terms of proper daily regimen and dietary regimen could help to prevent eye problems. Padabhyanga (foot massage) is one of the procedures mentioned in Dinacharya, an effective therapy for healing of eye disorders.

  • Objective : The use of herbal therapy is becoming an increasingly attractive approach for the treatment of various inflammatory disorders. The Alpiniae officinari Rhizoma is popular in Aisa as a traditional herbal medicine. Alpiniae officinari Rhizoma is a species of the ginger family(Zingiberacease). Method : This study was performed to investigate the anti-inflammatory effect of Alpiniae officinari Rhizoma extract by the methods of 'carrageenan induced paw edema' and 'Lipopolysaccharide-induced inflammatory mediators in mouse macrophage RAW 264.7 cells'. Result : We suggest that Alpiniae officinari Rhizoma extract decreased paw volume induced by plantar injection of carrageenan. Also Alpiniae officinari Rhizoma extract inhibited nitric oxide, prostaglandin $E_2$ production and induced nitric oxide synthase, cyclooxygenase-2 protein expression in Mouse macrophage RAW 264.7 cells stimulated with lipopolysaccharide. Conclusion : This study shows that Alpinia officinari Rhizoma extract seems to have anti-inflammatory effect by inhibition of nitric oxide, prostaglandin $E_2$ production and nitric oxide synthase, cyclooxygenase-2 protein expression.

  • Digital photographic analysis is currently considered as a routine procedure in clinic because periodic follow-up examinations can provide meaningful information for diagnosis. However, it is impractical to separately evaluate all suspicious lesions with conventional digital photographic systems, which have inconsistent characteristics of the environmental conditions. To address the issue, it is necessary for total diagnostic evaluation in clinic to integrate conventional systems. Previously, a multimodal digital photographic imaging system, which provides a conventional color image, parallel and cross polarization color images and a fluorescent color image, was developed for objective evaluation of facial skin lesions. Based on our previous study, we introduce a commercial product, "DermaVision-PRO," for routine use in clinical application in dermatology. We characterize the system and describe the image analysis methods for objective evaluation of skin lesions. In order to demonstrate the validity of the system in dermatology, sample images were obtained from subjects with various skin disorders, and image analysis methods were applied for objective evaluation of those lesions.

  • 가장 일반적으로 사용되는 주시시차 측정 장치는 Wesson 주시시차 카드이다. 주시시차곡선은 추가한 프리즘량과 주시시차량에 대한 함수이며, 주시시차 곡선에서 진단과 처방에 사용되는 값은 x-절편, y-절편, 기울기, 곡선 타입이다. Wesson 주시시차 카드를 이용하여 102명을 대상으로 주시시차를 측정하였는데, 이 연구의 목적은 Wesson 주시시차카드를 이용한 주시시차 검사법에 의해 주시시차의 방향과 분포 등을 알아보고, 진단과 처방에 응용하는데 있다. Wesson 주시시차 카드를 이용한 주시시차 측정 결과 type I은 63.0%, type II는 0.0%, type III는 25.0% type IV는 12.0%를 얻었다.
