Objectives: This is a case report regarding the effect of Korean traditional medicine on vision disorder and quadriplegia in a patient with neuromyelitis optica. Methods: We treated a patient who was diagnosed with neuromyelitis optica with Korean traditional medicine, including acupuncture, moxibustion, and herbal medicine (Gigugyanghyeol-tang gamibang) for 106 days. We evaluated the patient with the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI), Modified Barthel Index (MBI), Modified Ashworth Scale (MAS) Grade, and Numeric Rating Scale-11 (NRS-11). Results: After treatment, the patient's symptoms were improved. The ISNCSCI scores increased from 42 to 66 in motor score, from 152 to 196 in sensory score, and from A to D in the ASIA impairment scale; the MBI score increased from 9 to 33, while the score of the MAS Grade decreased from I+ to I, and the NRS-11 scores of vision disorder, spasticity, and tingling decreased from 10 to 7, 3, and 2-3, respectively. Conclusions: Korean traditional medicine may be effective for treatment of vision disorder and quadriplegia in patients with neuromyelitis optica.

Attention deficit hyperactivity disorder (ADHD) is a neurobehavioral developmental disorder characterized by a persistent pattern of inattention and/or hyperactivity, as well as forgetfulness, poor impulse control or impulsivity, and distractibility. The recommended evaluation includes documenting the type and severity of ADHD symptoms, verifying the presence of normal vision and hearing, screening for comorbid psychological conditions, reviewing the child's developmental history and school performance, and applying objective measures of cognitive function. Prevailing opinion characterizes ADHD as a disorder of executive function attributable to abnormal dopamine transmission in the frontal lobes and frontostriatal circuitry. A clearly defined etiology remains unknown, but studies suggest a strong genetic link. The aim of treatment is to decrease symptoms, enhance functionality, and improve well-being for the child and his or her close contacts. Stimulants remain the pharmacological agents of first choice for the management of ADHD, and psychosocial, behavioral and educational strategies that enhance specific behaviors may improve educational and social functioning in children with ADHD.

According to the Statistics Korea in 2017, the 10 leading causes of death contain a cardiac disorder disease, self-injury. In terms of these diseases, urgent assistance is highly required when people do not move for certain period of time. We propose an unusual event detection algorithm to identify abnormal user behaviors using dust, vision and activity sensors in their houses. Vision sensors can detect personalized activity behaviors within the CCTV range in the house in their lives. The pattern algorithm using the dust sensors classifies user movements or dust-generated daily behaviors in indoor areas. The accelerometer sensor in the smartphone is suitable to identify activity behaviors of the mobile users. We evaluated the proposed pattern algorithms and the fusion method in the scenarios.

Dissociative disorder is a psychiatric disorder characterized by a sudden loss of memory, but which has no organic disease or explanation. It usually occurs after heavy psychosocial stress or traumatic experience. A transient cerebral ischemic attack (TIA) is an acute episode of temporary and focal loss of cerebral function of vascular origin. TIAs are rapid in onset; symptoms reach their maximal manifestation in fewer than 5 minutes. Manifestations are of variable duration and typically last 2-15 minutes(rarely as long as 24 h). Most TIA durations are less than 1 hour. Of concern is the careful detection of changes in behavior, speech, gait, memory, movement, and vision. TIAs are uncommon in persons younger than 60 years. I treat 6 cases of Sudden Temporary Amnesia Patients with oriental medicine and they are improved. All of them had amnesia for $6{\sim}10\;hours$. During that time, they show behavioral changes and they are not on the state of unconsciousness. After recovery, they also forget what happen at the time. they have some emotional reason too. In conclusion, 4 cases of them belong to dissociative disorder and 2 other cases, TIA.

We propose a homology between thermodynamic systems and images for the treatment of time-varying imagery. A physical system colder than its surroundings absorbs heat from the surroundings. Furthermore, the absorbed heat increases the entropy of the system, which is closely related to its disorder as given by the definition of Clausius and Boltzmann. Because pixels of an image are viewed as a state of lattice-like molecules in a thermodynamic system, the task of reckoning the entropy variations of pixels is similar to estimating their degrees of disorder. We apply this homology to the uncalibrated stereo matching problem. The absence of calibrations alleviates user efforts to install stereo cameras and enables users to freely modify the composition of the cameras. The proposed method is also robust to differences in brightness, white balancing, and even focusing between stereo image pairs. These peculiarities enable users to estimate the depths of interesting objects in practical applications without much effort in order to set and maintain a stereo vision setup. Users can consequently utilize two webcams as a stereo camera.

목적: 양안개방형 자동굴절검사기를 이용하여 완전교정과 저교정 상태에서 실제 일어나는 조절 반응량을 측정하여 조절의 변화를 알아보고자 하였다. 방법: 20~30세($21.14{\pm}2.00$세)의 대학생 79명(남 58명, 여 21명)을 대상으로 타각적 자각적 굴절검사를 실시하여 완전교정은 시력이 1.0일 때, 저교정은 임의적으로 플러스 렌즈를 부가하여 0.8, 0.7, 0.6일 때의 조절 반응량을 5.0 m, 1.0 m, 0.50 m, 0.33 m, 0.25 m에서 측정하였다. 피검사자를 대상으로 주시거리에 따른 1.0, 0.8, 0.7, 0.6 시력 상태에서 조절 반응량의 변화를 비교 분석하였다. 결과: 우안 좌안 모두 완전교정 상태(1.0)가 저교정 상태(0.7) 보다 조절 반응량의 값이 크게 나타났다(p=0.000). 완전교정 상태가 저교정 상태(0.7) 보다 주시거리가 짧아질수록 조절 반응량의 변화가 더 크게 나타났다. 주시거리에 따른 시력과 조절 반응량의 상관관계는 거리가 짧을수록 더 낮게 조사 되었다. 결론: 장시간 근거리 작업은 조절기능에 영향을 줄 수 있으므로 저교정을 하여 눈의 안위를 편안하게 하는 것이 안정피로 증상을 해소하는데 도움이 될 것이다.

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.
