차량이 위치하고 있는 다양한 경사조건에 따라 사용자가 도어에 가하는 개폐 힘을 평지와 같도록 하기 위해 개폐보조 힘을 예측하는 모델을 제안하였다 . 학습에 앞서 모의실험장치로부터의 데이터는 외부 요인에 의한 오차를 가질 수 있다고 판단하였다 . 이러한 문제를 해결하기 위해 최소제곱법을 이용하여 구간마다 최댓값을 보정하였고 , 예측 값의 정확도를 높이는 방안을 제안하였다 . 그에 따른 결과를 인공신경망 모델을 통하여 검증하였고 예측 신뢰 도를 높였다 . 이와 같은 알고리즘 검증을 통하여 사용자가 평지와 유사한 힘으로 도어를 효과적으로 제어하도록 돕는 방안을 제시하였다 . \Ve proposed prediction model of assistance force for the user when use the automobile door to assist the deviation of required door force in the slope condition as needed in the plane condition. Before the training of data we supposed the data can have some error by external factors. So we used Least Squares Method(LSM) to resolve it and proposed the plan can improve accuracy of the prediction force data by revising maximum value. We validated the result Artificial Neural Network(ANN) and improved confidence of prediction force. As a result we proposed to control the door as a similar force regardless of a slope condition.

The electrocardiogram of frogs were obtained in winter (January), spring (April), summer (July) and autumn (September and November). Electrocardiograms were recorded applying electrodes to the atria, ventricle and apex of the heart by unipolar or bipolar leads. V wave was recorded prior to P wave, for the presence of the sinus venosus which controls the automaticity of the frog heart, in four seasons. Regardless of the leads or the position of the electrodes P wave was diphasic and wide. According to the rise of temperature the rate of heart beat was increased, and V-P and P-R interval were shortened. Two regression line between R-R interval and both V-P interval and P-R interval were drawn. These were calculated as V-P interval=1 0.276R-R $interva1+0.067{\pm}0.15$ (sec.) and P-R interval=0.179R-R $interva1+0.155{\pm}0.1$ (sec). From these calculation the larger gradient of V-P interval than P-R interval was suggestive that the heart rate is more dependent on the changes of V-P interval than that of P-R interval. Changes of the heart rate were also measured in four seasons and artificial temperatures. Two regression lines between the heart rate (H.H.) and both seasonal temperature (T) and artificial temperature, were drawn. These two lines were calculated as H.R.=20+3.71 (T-10) and H.R.=32+1.425 T respectively. From two gradients of the above equations it is considered that the changes of the heart rate in artificial temperature were milder than that in seasonal temperature. The number of RBC and WBC of frogs were measured in four seasons and a tendency of the changes was observed according to the seasonal variation.

본 논문에서는 차량이 주차된 지형의 조건에 따라 적용되는 도어 개폐 보조력 예측 모델을 제시하였다. 경사도, 사용자의 힘 등의 조건에 따른 개폐력 설정을 위하여 작동 보조력에 대한 학습 모델을 구현하여 비교하였고, 예측 모델의 학습을 위하여 축소모형을 제작하여 실험을 통해 학습데이터를 얻을 수 있는 실험 모델을 구성하였다. 실제 보상력 데이터를 학습, 반영하여 적정 값을 도출할 수 있는 학습 알고리즘을 개발하고, 이를 적용할 수 있는 시스템을 개발하였다. 학습 방법 중에서 인공신경망(Artificial Neural Network, ANN)과 서포트 벡터 머신(Support Vector Machine, SVM) 알고리즘을 적용하여 비교·검증하였다. 실제 측정값과 비교·검증한 결과, 차량의 도어 개폐 보조력 예측을 위해서 서포트 벡터 머신의 상대적으로 높은 적용성을 확인할 수 있었으며, 이 예측 모델을 활용하여 경사, 사용자의 힘에 따라 도어 개폐 구동 모터가 보상해야 할 적정한 힘을 예측하여 시간에 따라 구동함으로써 사용자가 평지와 같은 힘으로 문을 제어할 수 있는 시스템 구성을 제시 하였다. We developed a prediction model of assistance force for the opening/closing of an automobile door depending on the condition of the parking ground. The candidates of the learning models for the operating assistance force were compared to determine the proper force according to the slope and user's force, etc. The reduced experimental model was developed to obtain learning data for the estimation model. The learning algorithm was composed to predict the assistance force to incorporate real assistance force data. Among these algorithms, an Artificial Neural Network (ANN) and Support Vector Machine(SVM) were applied and the adaptability was compared between these models. The SVM provided more adaptability for the learning process of the door assistance force prediction. This paper proposes a system for determining the assistance force to control a door motor to compensate for the deviation of required door force in the slope condition, as needed in the plane condition.

By means of drawing eccentricity distribution curve, the distribution curve of the ratio of the short diameter to the long diameter and the distribution curve of the area of surface of the red blood cells under the microscope in each stage of the development of Rananigro-maclata follow sesults are obtained. In each stage of the development of Rana nigromaculata mountain shape above mantioned three kind distribution curves have been drawn. But the locations of those curves move as the development of individual goes. In the stage of tadploe most of red blood cells are round or nearly round, but the number of those red blood cells decreases and the number of the red blood cells the eccentricity of which are greater increases as the development of individual goes. On the area of surface of the red blood cell under the microscope, the number of the red blood cells the area of surface of which are greater decreases and the number the red blood cells the area of surface of which are smaller increases as the development goes in the stage of tadpole, but in the stage of frog the number of the red blood cells the area of surfaca of which are greater increases and the number of the red blood cells the area of surface of which are smaller decreases as the develoment of individual goes.

In order to know the diagnostic value of pancreas scanning, scans were performed on 23 cases using selenium^(75)-Selenomethionine. These cases were also given egg white, probanthine and morphine. 1) Good visualization of the pancreas scanning was observed on 19 cases, presumably with normal pancreas. 2) A case which showed diffusely decreased uptake on pancreas scanning was proven to have lesions in the bile duct and the gall bladder. 3) Of those two cases which showed localized cold area, ond had pancreas cyst and the other one was not explored. 4) A case which showed no visualization of the pacreas was proven to have pancreatic carcinoma. 5) Two cases which showed widened duodenal loop by upper gastro-intestinal series revealed normal pancreas scanning, and no pancreatic disease was found in both cases. $quot;

Ether 全身麻醉와 Barbital Sodium 및 Thiopental Sodium의 In Vitro 添加가 家兎 赤血球의 酸素消費量에 미치는 影響

申鉉鑽 慶北大學校 1975 論文集 Vol.20 No.-

It has been reported that the addition of some barbiturate derivatives enhances potassium transport through the red cell membrane and inorganic phosphate level of the red cell. However, little has been known of the effect of barbiturate derivatives on the oxygen consumption rate (QO_2) of the red cell. In the present study, the changes in the QO_2 of the rabbit red cells were measured by the standard Warburg manometric methods following subjecting the rabbits to the general ether anesthesia, and adding barbital sodium or thiopental sodium to the blood of the rabbit. A comparision was made with the normal group where the QO_2 of the normal rabbit blood was measured, and with the control group where the red cells were mixed with saline only. The results thus obtained are as follows: 1) QO_2 of the normal group showed a tendency of a gradual decrease as the experiment proceeded, the values being 1.01± 0.32×10 exp (-9) ㎕ O_2/RBC/10 min in the first 10 min, and 0.43±0.17×10 exp (-9) ㎕ O_2/RBC/10 min in the last 10 min. 2) QO_2 of the control group were less than the normal as 0.70±0.22×10 exp (-9) ㎕ O_2/RBC/10 min in the first 10 min and 0.33± 0.14×10 exp (-9) ㎕ O_2/RBC/10 min in the last 10 min. 3) The general ether anesthesia produced a significantly lower values of QO_2 comparing with the normal regardless of the degree and time after the anesthesia. 4) The addition of barbital sodium in the concentratration of 1 : 1600 resulted in the lower QO_2 than the control. 5) The QO_2 were found to be increased with the addition of barbital sodium in the concentration of 1 : 2400. 6) Generally elevated QO_2 levels were observed with the addition of thiopental sodium in the concentration of 1 : 800. 7) A tendency of the decreased QO_2 levels were observed with the addition of thiopental sodium in the concentration of 1 : 1200.
