Objectives : This study aims to examine the background of how the theory of there being no excess pattern of the Kidney has been carried on by looking at contents on Kidney excess patterns pre-Qianyi and at those negating the possibility of Kidney excess post-Qianyi. The history of the Kidney draining method for Kidney excess patterns was studied as well. Methods : Key words such as 腎實(kidney excess), 腎無實(no excess of the kidney), 瀉腎(draning the kidney) were entered into major database such as the Sikuquanshu to excavate contents on both Kidney excess and non-excess from medical classics. Results & Conclusion :In the Neijing, there are few mentions of symptoms due to Kidney excess. The theory of Kidney non-excess marks its beginning with Qianyi, who argued that Kidney manages deficiency in children only. Afterwards, some doctors expanded this theory beyond children and applied it as a general principle of the body. Based on the theory of there being no excess of the Kidney, it could be thought that while there could be excess symptoms of the Kidney, the root mechanism lies in Kidney deficiency. The importance of the Kidney as the basis of heaven-bestowed life, which is responsible for reproduction, growth and development, is what motivated the theories on the Kidney as what needs to be preserved and never drained. It could also be argued that the symptoms of Kidney excess, which were mentioned post-Neijing, got dealt with within the context of other Zhangfu differentiation patterns and deficiency symptoms, and became increasingly less designated to Kidney excess.

Objectives : In pediatrics, one of the most difficult thing might be medication because infant or child cannot take medicine easily. In traditional medicine, Korean taffy or paste preparations sometimes prescribed. Xiao'eryaozhengzhijue was published by Qianyi in 1119 and is specialized for pediatrics text. So I tried to research paste preparations in Xiao'eryaozhengzhijue. Methods : I derived paste preparations from Xiao'eryaozhengzhijue ; paste preparations named on it, and used as paste preparations etc. Results : 1. There were external and internal application of paste preparations. 2. Diverse secondary materials were used for making paste preparations. 3. Several chief complains were recorded in Xiao'eryaozhengzhijue. Conclusions : Paste preparations are really useful way to disease of pediatrics because infant or child cannot take his or her medicine easily. Through the research, I could find out the facts that there are diverse shapes of paste preparations and usages of paste preparations in Xiao'eryaozhengzhijue.

Objectives : Focusing on Wujutong's critiques for Xiebaisan misuse, this study investigates how Xiebaisan and its constituent drugs have historically been used by medical doctors and analyzes the disputes in the controversial context with a summary. Methods : The contents of Xiebaisan prescription were collected and examined from the past literature and medical database, and the issues related to the debate were examined by analyzing the contents. Results : In the results of exploring the opinions of medical doctors, in general, Xiebaisan and Sangbaipi, a major medicinal drug, were seen to play a role in the work of reinforcing and reducing. In particular, Ye Tianshi was used with cold and pungent medicine to Xiebaisan as a method of releasing heat with pungent medicine for acute fever in spring, and at the same time, care was taken to avoid depletion of secretion in the stomach. Conclusions : Wujutong's critique is that in early symptoms of viral infection, the misuse of Xiebaisan seems to emphasize the adverse effects of the illness. It is hoped that further research on Xiebaisan incremental medication will be conducted in the future to help clinical applications of Xiebaisan system medication.

We estimated various neuron functions to construct of engineering neurons, which are the combination of sigmoid, linear, sine, quadric, double/single bended, soft max/minimum functions. These combinations are estimated by the property on the potential surface between the learning points, calculation speed, and learning convergence; because the surface depends on the inference ability of a neuron system; and speed and convergence are depend on the efficiency on the points of engineering applications. After the evaluating discussions, we can select more appropriate combination than original sigmoid function´s, which is single bended function and linear one. The combination ...

In this paper, we propose a solver for differential equations, using a multi-layer neural network. The multi-layer neural network is a transformer function originally where the function is differential and the explicit representation has been developed. The learning determines the response of neural networks; however, the response is not equal to the output values. The differential relations are also the response. The differential conditions can be also set as teaching data; therefore, there is a possibility to reach a new solver for the differential equations. Since it is unknown how to define the input data for the neural network solver during long terms, we could not derive the expressions. Recently, the analogue type neural network is known and it transforms any vector to another The "any" must be...

We propose a neural network solver for an inverse problem. The problem is that input data with complete teaching include defects and predict the defect value. The solver is constructed of a three layer neural network whose learning method is combined from BP and reconstruction learning. The input data for the defects are unknown; therefore, the circulation of an arithmetic progression replaces them; rightly, the learning procedure is not converged for the circulation data vut for the normal data. The learning is quitted after such a learning status id kept. Then, we search a minimum of the differences between teaching data and output of the circulation. Then, we search a minimum of the ...

In the structural health monitoring field, damage detection has been commonly carried out based on the structural model and the engineering features related to the model. However, the extracted features are often subjected to various errors, which makes the pattern recognition for damage detection still challenging. In this study, an automated damage identification method is presented for hanger cables in a tied-arch bridge using a convolutional neural network (CNN). Raw measurement data for Fourier amplitude spectra (FAS) of acceleration responses are used without a complex data pre-processing for modal identification. A CNN is a kind of deep neural network that typically consists of convolution, pooling, and fully-connected layers. A numerical simulation study was performed for multiple damage detection in the hangers using ambient wind vibration data on the bridge deck. The results show that the current CNN using FAS data performs better under various damage states than the CNN using time-history data and the traditional neural network using FAS. Robustness of the present CNN has been proven under various observational noise levels and wind speeds.

본 연구의 목적은 흡수선량 재구성, 방사선 치료간의 재구성된 선량의 등록, 선량-체적 히스토그램의 생산등을 수행하는 선량 재구성의 임상적 응용시스템을 만들고 그것을 변형된 전립선 팬텀에 적용하는 것이다. 이를 위해 변형가능한 전립선 팬텀을 20 cm 깊이와 40 cm너비의 물팬텀에 집에 넣었다. 이것의 영상을 얻고, 전립선, 정낭 및 항문의 윤곽을 그렸다. 동일 평면에서 네개의 조사문을 이용하여 세기 변조계획을 세웠다.항문에 20 ml의 물풍선을 삽입하여 장기를 변형시켰다. 영상을 다시 획득하여 위 장기의 윤곽을 그렸다. XVMC몬테칼로 코드를 사용하여 두 팬텀및 EPID내에서 선량반응 인자를 계산하였다. 세기변조계획에서 얻어진 방사선을 두팬텀에 조사하여 EPID에서 적분형 영상을 얻었다. Demons 방법을 사용하여 변형된 팬텀을 변형전 팬텀에 등록시켰다. 이를 통해 단위체적별 위치변이 정보를 얻었고 이를 이용해 두 팬텀의 재 구성된 선량을 합하여 변형전 팬텀에 생산해 냈다. 순방향으로 계산된 치료계획 선량을 합산된 재구성된 선량과 비교하였다. 200 cGy에서 전립선과 정낭이 받든 체적은 차이를 거의 보이지 않았으나, 210 cGy 이상에서는 3%가량 차이를 보였다. 항문에서는 150-200 cGy영역에서 재구성된 선량에 의하여 받은 체적은 치료 계획과 비교하여 3% 이상 적었다. 본 연구를 통하여 선량 재구성의 임상적 응용시스템이 성공적으로 만들어 졌다. 변형된 전립선 팬텀에 적용되어 작지 않은 선량의 차이를 목표장기와 보호 장기에 보였다.
