Objective : The aim of this study is to investigate the effectiveness of ShinBaro Pharmacopuncture in the treatment of patients with Lumbar spine Herniated Nucleus Pulposus. Methods : We investigated 20 cases of patients with lumbar disc herniation and devided into two groups. Experimental group were treated with ShinBaro Pharmacopuncture with integrated package treatment and control group were treated the same therapies without ShinBaro Pharmacopuncture. To evaluate the treatment effects of two groups, we used numeric rating scale(NRS), oswestry disability index(ODI). Results : In NRS of lumbar and sciatica pain and ODI, that of experimental group was much more improved than control group, and decrement of NRS of lumbar pain showed statistical significance along with the duration of treatment. Conclusions : ShinBaro Pharmacopuncture was thought to be effective for relieving symptoms of lumbar spine herniated nucleus pulposus, although further study is needed.

전병철(Byung Chul Jun),장대진(Dae Jin Jang),이민철(Min Chul Lee) 대한기계학회 2021 大韓機械學會論文集B Vol.45 No.8
본 연구에서는 모델 가스터빈 연소기로부터 계측된 고속화염 이미지를 활용해 기계 학습을 수행하여 연소 불안정을 진단하였다. 기계학습에 사용된 이미지는 연소불안정이 안정영역에서 불안정 영역으로 천이되는 조건을 대상으로 초고속 카메라를 이용하여 8 kHz의 속도로 취득하였다. 연소불안정 여부를 판단하기 위하여 CNN과 CNN+LSTM의 두 가지 기계학습 모델을 개발・적용하였고, confusion matrix와 accuracy, recall, precision, F1-score 값을 활용하여 각 모델의 진단성능을 평가하였다. CNN 모델은 단일 이미지만으로 학습하기에 48.92~100%의 정확도의 일부 부정확한 분류를 수행하는 것을 확인하였고, 이에 반해 시계열 화염이미지 데이터를 활용한 CNN+LSTM 모델은 98.97~100%의 매우 정확한 분류를 수행하는 것을 확인하였다. In this study, combustion instability has been diagnosed by performing machine learning using the flame images measured from a model gas turbine combustor. The images were acquired with an ultra-high-speed camera at the rate of 8 kHz in the transition condition of combustion instability from stable to unstable regimes. To judge the onset of combustion instability, two machine learning models of CNN and CNN+LSTM were developed and applied, and their diagnostic performances were evaluated using confusion matrix, accuracy, recall, precision and F1-score. It was confirmed that the CNN model performs partially inaccurate classification with an accuracy of 48.92~100% because it was trained and judges with only a single image, whereas the CNN+LSTM model, which uses time-series flame image data, performs very accurate classification with an accuracy of 98.97~100%.

Objectives The aim of this study is to investigate the difference of effectiveness according to Pharmacopuncture treatment depth on lumbar spinal herniated Intervertebral Disc. Methods We investigated 40 cases of patients with lumbar disc herniation and devided into two groups. Each 12 cases of patients complete treatment and 16 cases of patients droped out. Experimental group was treated with 3cm depth Pharmacopuncture with integrated package treatment and control group was treated the same therapies without 1cm depth Pharmacopuncture. To evaluate the treatment effects of two groups, we used numeric rating scale(NRS), oswestry disability index(ODI). Results In NRS of lumbar and sciatica pain and ODI, that of experimental group was much more improved than control group, and decrement of NRS of lumbar pain and ODI showed asymptotically statistical significance along with the duration of treatment. Conclusions 3cm depth Pharmacopuncture was thought to be effective for relieving symptoms of lumbar spine herniated nucleus pulposus rather than 1cm depth Pharmacopuncture , although further study is needed.

본 연구에서는 가스터빈 연소기 내에서 연소 불안정을 진단하기 위해 주로 사용되는 동압 측정법의 타당성을 검증하고, 오차를 최소화하기 위한 보정식을 제안하였다. 비연소 상태에서 원기둥 형상의 캔형 가스터빈 모사 연소기의 일측에 부착된 스피커를 이용하여 50Hz~6,000Hz로 가진 주파수를 변경하였을 때, 라이너의 길이 방향으로 벽면 매설방식(flush mount type)으로 설치된 6개의 동압 센서를 이용하여 연소실 내 동압이 측정되었다. 일부 실험 조건에서 오측정 현상을 관찰되었고, 정상파 모드 분석을 통해 원인을 파악하였다. 이러한 계측 오차를 줄이고자 두 개의 보정식을 제안 · 검증하였고, 이 결과는 가스터빈 연소기 내 연소 동압 측정의 정확성을 향상시키고 연소 불안정 사고 위험성을 감소시킬 것으로 기대된다. In this study, the adequacy of the conventional measurement method of dynamic pressure, which is mainly used to diagnose combustion instability in a gas turbine combustor, was checked and new correction equations are proposed to minimize the error. When changing the excitation frequency from 50 Hz to 6,000 Hz using a speaker installed at one end of a can-type cylindrical model combustor in a non-combustion state, dynamic pressure in the combustion chamber was measured using 6 flush-mount-type dynamic pressure sensors installed along the liner in a longitudinal direction. Measurements errors for several experimental conditions were examined and the cause of this phenomenon was identified through standing wave mode analysis. To reduce this error in measurement, two correction correlations are proposed whose validity was verified. These results are expected to improve the measurement accuracy of dynamic pressure in a gas turbine combustor and, consequently, to reduce the risk of accidents from combustion instability.

N/A We performed 1856 cases of ERCP from 1976 to August 1985 and among them we analyzed 116 cases of ERCP after biliary stone surgery. 1) Among 1856 cases of ERCP, biliary tract diseases were 709 cases(38.2%), and among 709 cases, 336 cases(47.4%) had stones in the biliary tract. Among 709 cases, 116 cases of ERCP after biliary tract surgery demonstrated following data. 2) Almost all cases of 116 cases(16.4%) of ERCP received cholecystectomy due to gall stone and the duration from operation to ERCP were variable. Many cases received operation in the private hospital but 31.4% cases received operation in the general hospital and university hospital. 3) Sex distribution in ERCP 116 cases of biliary tract surgery showed predominence in the female(62.1%) and most of the cases were over 40 years of age. SGOT and serum bilirubin were normal in half the cases, but alkaline phosphatase was elevated in 80 cases. Clinical impression in ERCP 116 cases of biliary tract surgery were in the order of remained CBD stone(67 cases), obstructive jaundice(24 cases), T-tube CBD stone(10 cases), pancreatitis(5 cases), cholangitis(4 cases), postop jaundice(2 cases), etc. 4) 111 cases in 116 cases of biliary tract surgery were performed ERCP and ERCP demonstrated recurrent or remained biliary tract stone in 62 cases(53.4%) and chronic pancreatis in ERCP was demonstratated in 52 cases(44.8%) So we think that biliary stone induces duronic pancreatitis. Among 62 cases of recurrent or remained CBD stone EST was performed in 35 cases and after EST good results were obtained.
