Objectives: Facial diagnosis is an important part of clinical diagnosis in traditional East Asian Medicine. In this paper, we proposed a model to quantitatively classify cold sensitivity using a fully automated facial image analysis system. Methods: We investigated cold sensitivity in 452 subjects. Cold sensitivity was determined using a questionnaire and the Cold Pattern Score (CPS) was used for analysis. Subjects with a CPS score below the first quartile (low CPS group) belonged to the cold non-sensitivity group, and subjects with a CPS score above the third quartile (high CPS group) belonged to the cold sensitivity group. After splitting the facial images into train/validation/test sets, the train and validation set were input into a convolutional neural network to learn the model, and then the classification accuracy was calculated for the test set. Results: The classification accuracy of the low CPS group and high CPS group using facial images in all subjects was 76.17%. The classification accuracy by sex was 69.91% for female and 62.86% for male. It is presumed that the deep learning model used facial color or facial shape to classify the low CPS group and the high CPS group, but it is difficult to specifically determine which feature was more important. Conclusions: The experimental results of this study showed that the low CPS group and the high CPS group can be classified with a modest level of accuracy using only facial images. There was a need to develop more advanced models to increase classification accuracy.

1. Objectives: In SCM, a personal Sasang constitution must be determined accurately before any Sasang treatment. The purpose of this study is to develop an objective method for classification of Sasang constitution. 2. Methods: We collected samples from 5 centers where SCM is practiced, and applied two-stage decision tree analysis on these samples. We recruited samples from 5 centers. The collected data were from subjects whose response to herbal medicine was confirmed according to Sasang constitution. 3. Results: The two-stage decision tree model shows higher classification power than a simple decision tree model. This study also suggests that gender must be considered in the first stage to improve the accuracy of classification. 4. Conclusions: We identified important factors for classifying Sasang constitutions through two-stage decision tree analysis. The two-stage decision tree model shows higher classification power than a simple decision tree model.

1. Objectives: Voice diagnosis has been used to classify individuals into the Sasang constitution in SCM(Sasang Constitution Medicine) and to recognize his/her health condition in TKM(Traditional Korean Medicine). In this paper, we purposed a new speech classification algorithm for Sasang constitution. 2. Methods: This algorithm is based on the SVM(Support Vector Machine) technique, which is a classification method to classify two distinct groups by finding voluntary nonlinear boundary in vector space. It showed high performance in classification with a few numbers of trained data set. We designed for this algorithm using 3 SVM classifiers to classify into 4 groups, which are composed of 3 constitutional groups and additional indecision group. 3. Results: For the optimal performance, we found that 32.2% of the voice data were classified into three constitutional groups and 79.8% out of them were grouped correctly. 4. Conclusions: This new classification method including indecision group appears efficient compared to the standard classification algorithm which classifies only into 3 constitutional groups. We find that more thorough investigation on the voice features is required to improve the classification efficiency into Sasang constitution.

1. Objectives This study focuses on the Validity of the Questionnaire about Sasang Constitution Classification for Mongolians 2. Methods By using the way of backward elimination, certain variables are chosen from the 438 cases whose physical conditions are absolutely diagnosed. After that, discriminant analysis for the selected variables has been done to obtain the physical constitution equation and the accuracy ratio of diagnosis which are useful for physical constitution diagnosis. 3. Results and Conclusions (1) In tile Validity for the Questionnaire of Sasang Constitution Classification for Mongolians, the accuracy ratio of diagnosis of Taeyangin is 100%, Soyangin 62.5%, Taeumin 76.7%, and Soeumin 66.1% respectively as a result of the discriminant analysis employing Cronbach's alpha coefficient. On the whole, the accuracy ratio of diagnosis is 70.1%. (2). In the Validity for the Questionnaire of Sasang Constitution Classification for Mongolians, the accuracy ratio of diagnosis of 70.1% means that it beats the maximum chance criterion of 41.4% and the proportional chance criterion of 34.4% by 28.7% and 35.7% respectively. Conclusively, this questionnaire has discriminant power.

Background In Sasang Constitutional Medicine (SCM), human beings are classified into four constitutions: Taeyangin, Taewnin, Soyangin, and Soeumin. SCM presents various lifestyles and treatments for each constitution. The problem of SCM is that its diagnosis is so subjective that the result of the diagnosis depends on the doctor. In order to solve this problem, multiple approaches have been objectively researched. To use a questionnaire is the most common method among the different approaches. Since there are a few problems in the Questionnaire for the Sasang Constitution Classification II (QSCC II), which in recent days has been used frequently, the necessity of a new questionnaire has arisen. Objective The purpose of this study is to develop a new questionnaire for the objectivity of the Sasang Constitution Classification by complementing the existing questionnaire. Methods In order to search for the existing questionnaire's problems, I first compare the ratio of the amount of questions regarding external appearance to that of questions of mental characteristics and physiologic & pathologic symptoms in QSCCII and QSCCII +. We created the new questionnaires by reinterpreting ${\ulcorner}Dongyi$ Soose $Bowon{\lrcorner}$ through SCM professors' and medical residents' discussion and by adding some items related to the diagnosis about the constitution from other SCM books and clinical experience. Results 1. The new questionnaire for the Sasang Constitution Classification is self-reported questionnaire based on a multiple choice system of 4 questions. 2. The new questionnaire for the Sasang Constitution Classification consists of 28 questions, which include 7 questions about external appearance, 4 questions about mental characteristics, and 17 questions about physiologic & pathologic symptoms. 3. The new questionnaire for the Sasang Constitution Classification consists of 24 questions of Taeyangin, 28 of Taeumin, 28 of Soyongin, 28 of Soeumin. 4. We will have to verify validity and reliability of new questionnaire for rhe Sasang Constitution Classification.
