A varicose vein of the lower limbs is dilated, tortuous and elongated vein. Western medical treatment involves conservative management, sclerotherapy, and surgery. Currently, internal medicinal treatment is inadequate. Recently a patient was diagnosed with varicose veins of the lower limbs based on clinical symptoms. In this case, Guibi-tang was administered and clinical symptoms improved. This report suggests that oriental medicinal treatment is efficacious in treating varicose veins of the lower limbs. We think that further oriental medical studies on various surgical diseases are needed.

Lumbar spinal stenosis results from the progressive combined narrowing of the central spinal canal, the neurorecesses, and the neuroforaminal canals. In the absence of prior surgery, tumor, or infection, the spinal canal may become narrowed by bulging or protrusion of the intervertebral disc annulus, herniation of the nucleus pulposis posteriorly, thickening of the posterior longitudinal ligament, hypertrophy of the ligamentum flavum, epidural fat deposition, spondylosis of the intervertebral disc margins, or a combination of two or more of the above factors. Patients with spinal stenosis become symptomatic when pain, motor weakness, paresthesia, or other neurologic compromise causes distress. In one case, we administrated oriental medical treatment with acupuncture treatment and herb-medicine. Oriental medical treatment showed desirable effect on lumbar spinal stenosis.

최근 스마트 기기에서 오디오 데이터를 이용하는 응용 기술들이 증가하면서, 오디오 데이터에서 관심 있는 구간을 찾아내는 기술의 필요성이 증가하고 있다. 본 논문에서는 Perceiver 모델을 활용하여 오디오 데이터에서 사람의 음성 구간을 검출하고 축약하는 방법을 제안한다. Perceiver 모델은 복잡한 입력 데이터에 대하여 Self-attention을 기반으로 특징을 추출하면서 이전의 특징을 다음 입력으로 다시 학습하는 특징을 갖고 있어서 연속적인 데이터인 오디오에 효율적으로 적용할 수 있다. 외부 및 자체에서 수집한 음성과 비음성 데이터셋에 대하여 실험을 진행하였고, 10초 단위 세그먼트에서 대해서 92.4%의 검출 정확도를 달성하였다.

Liver cirrhosis is a disease of the liver in which normal cells are replaced by scar tissue. This condition results in the failure of the liver to perform many of its usual functions. Liver cirrhosis include acsites, jaundice, portal hypertension, varices etc. This report is about one case of ascites with liver cirrhosis. In this case, we administrated Taeumjowetang-gamibang was administered and acupuncture was done in treatment of ascites and its symptoms. After administration of Taeumjowetang-gamibang medication, clinical symptoms and prominently improved and ascites dwindled to nothing. This reports suggests Taeumjowetang-gamibang has desirable effected on ascites.

Recently there has been an increase in annual per capita consumption of alcohol beverage and the incidence of Alcoholic liver disease is steadily and significantly increasing. Alcoholic liver disease includes alcoholic fatty liver, alcoholic hepatitis, alcoholic cirrhosis and it may lead to systemic influence, in a case of CVA. This report is about one case's treatment for ICH with alcoholic liver disease. In this case, we administrated Taeumjowetang and did acupuncture treatment to a patient suffering from ICH with alcoholic liver disease and its withdrawal symptoms. After administration of Taeumjowetang medication, clinical symptoms and liver function were prominently improved. This report showed that Taeumjowetang might be useful for alcoholic liver disease.

We designed the flyback planar transformer, which had 8 W capacity, with 70 V input voltage and 8.2 V output voltage for the establishment of design method and the confirmation of application possibility. The numerical value of inductance measured under the switching frequency of 120 ㎑ was 1650 μH, which was the inductance efficiency of 85~87% against theoretical value. The A.C. resistance of primary and secondary coil was 4.2 Ω and 0.25 Ω respectively, On the other hand, the quality factor for each wound numbers showed quite a high value of 158 and 75 respectively. And the Coupling Factor was 0.96~0.97 under 120 ㎑ switching frequency. The inductance rapidly increased as the thickness of the core plane increased until it became 1.4 ㎜ but under the thickness more than 1.4 ㎜, there was no substantial change. Therefore, the critical value of the plane thickness of core was 1.4 ㎜. And the shape of the output wave of the planar transformer at 70V input voltage was a stable square wave.

Objective : Solar ultraviolet (UV) light can cause photoaging of human skin. Many researchers have focused on effective prevention to mitigate the aging process. This study was aimed to investigate anti-wrinkle effects of pomegranate concentration solution (PCS) using photoaged hairless mouse model. Method : To clarify the protective effect of PCS against UVB-induced photo-damage, water capacity was measured with transepidermal water loss (TEWL) in SKH-1 hairless mice. In addition, image of skin replicas was analyzed. Results : Our results showed that the PCS treatment protects skin against UVB-induced photoaging, based on the parameters including moisture capacity and TEWL. According to visual assessment of skin replica, application of 1 ml/kg PCS inhibited UV-induced wrinkle formation in mice skin as compared to the vehicle-applied control mice. Conclusion : Taken together, these results indicated that PCS could improve skin wrinkle formation induced by UVB irradiation in SHK-1 hairless mice. PCS could be applied as an anti-wrinkle agent.

Medical images in clinical practice are analyzed by pathologists, requiring human and time resources. Recently, deep learning methods that can predict the location of specific diseases in medical images has been developed. Also, regularization, constraints, and augmentation are introduced to solve data scarcity problems. This paper proposes an algorithm to detect multiple sclerosis lesions using Residual 3D U-Net. In particular, detection accuracy is improved through preprocessing and random patch enhancements. To verify the performance of the proposed algorithm, MS lesion datasets from 2008 MICCAI MS lesion segmentation challenge was used and compared with 3D U-Net. As a result, 70% DSC and 52% IoU were achieved, and 5.9% DSC and 6.9% IoU accuracy were improved. Quantitatively, detection results showed satisfactory performance except for local areas within the entire MRI image.
