The purpose of this study was to find out the body shape characteristics of each Sasang constitution typology. The constitution type of the subjects was determined by Sasang Constitution Analysis Tool(SCAT) and a Sasang specialist. The body circumference of the subjects and their respective proportions were analyzed. Concordance rates between SCAT and the specialist were 33.0% and 41.5% for men and women, respectively, and Soyangin had the lowest concordance rate. Forehead/neck, chest/iliac, rib/iliac, and rib/curvature circumference ratios of female subjects showed the same results in both SCAT and the specialist. In determining the constitution type, it was confirmed that the ratio between specific circumferences can be a more meaningful criterion than the circumference.

The purpose of this study is to help classifying Sasang Constitution through correlation with sound characteristic. This study was done it under the suppose that Sasang Constitution has correlation with sound spectrogram. The following result were obtained about correlation between sound spectrogram and Sasang Constitution by comparison and analysis 1. Soeumin answered his voice low tone, smooth and quiet in the survey. Soyangin answered his voice high, clear, fast and speaking random. Taeumin answered his voice low, thick and muddy. 2. Taeyangin was significantly slow compared with the others in the time of reading composition. Taeyangin was significantly slow compared with the others in Formant frequency 1. Taeyangin was significantly discriminated from Soeumin in Formant frequency 5. Taeyangin was significantly low compared with the others in Bandwidth 2. Soeumln was significantly low compared with Taeyangin in Pitch Maximum and Pitch Maximum-Pitch Minimum. Taeyangin was significantly high compared with the others in Energy mean. 3. In list of specification, the discrimination rate was higher than that by lists of 13 in the results of Multi-dimensional 4-class minimum-distance. The discrimination rate of three disposition except Soyangin was higher than that of four disposition in the results of One way ANOVA and Analysis of dis crimination in SPSS/PC+. In CART, the estimate rate of Sasang Constitution discrimination was higher than any other method. It is considered that there is a correlation between sound spectrogram and Sasang constitution according to the results. And method of Sasang constitution classification through sound spectrogram analysis can be one method as assistant for the objectification of Sasang constitution classification.

Objectives It is very important to diagnose Sasang Constitution (SC) correctly. The aim of this study was to reveal the concordance and validity of the specialists in Sasang Constitutional Medicine (SCM). Methods Three experts who had more than 5 years of experience and used more than 90% of Sasang Constitutional prescription in clinical practice of SCM participated in this study. The data composed of body shape, face, voice, temperament and physio-pathological symptoms were collected in the Korea Constitutional Multicenter Bank and 81 subjects' data were extracted randomly. The experts reviewed all 81 subjects data independently. Kappa analysis was conducted. Results 1) The concordance is from 52.5% to 68.4% among three experts. 2) The validity between individual expert and gold standard is from 54.3% to 63% and Kappa's coefficients are from 0.283 to 0.421. 3) The validity is from 68.5% to 70.7% when two or three experts agree the Sasang constitution independently and 75.7% when all of experts agree it. Conclusions The concordance and validity of experts in SCM seems to be moderate. We think further study is needed.

In this paper, we propose an efficient method to classify human facial impression using frontal face image. The features that represent the shape of eye, jaw and face are used. The proposed method employs PCA, LDA and SVM in series. PCA is used to project the feature space to a low dimensional subspace. LDA produces well separated classes in a low dimensional subspace even under severe variation. This results in good discriminating power for classification. SVM is used to classify the data. Human face has been classified for 8 facial impressions. The experiments have been performed for many face images, and show encouraging result.

1. Objectives : In Sasang constitutional medicine, it has been known that diagnosing Sasang constitution correctly is mostly important. We had developed an Integrated Sasang Constitutional Analysis Tool (SCAT) ${\beta}$-version using face, voice, body shape and questionnaire before. The purpose of this study is to suggest whether SCAT ${\beta}$-version is reliable or not. 2. Methods : We collected 371 subjects from 6 oriental medical clinics. We analyzed the Sasang constitutional diagnostic results using Kappa and coincidence rates between experts in Sasang constitution and SCAT ${\beta}$-version which was developed on the basis of face, body shape, voice and characteristics and symptom questionnaire data. 3. Results : The agreement rates between SCAT ${\beta}$-version and experts was 69.3% in total, and 73.2%, in Taeeumin, 70.8% in Soeumin, and 56.9% in Soyangin in detailed. The Kappa was 0.510 (p value<.000). There was an increasing trend of agreement rates and kappa value corresponded to increasing constitutional probability. When The constitutional probabilities were changed from below 40%, to over 40%, 50%, 60%, the agreement rates corresponded from 50.8% to 79.5%, 91.4%, 95.7% respectively. 4. Conclusions : A SCAT combined with a constitutional probability seemed to help experts to diagnose a patient's Sasang constitution correctly.

1. Objective : This study aimed to know the concordance coefficient and diagnostic trend of 6 Sasang constitution diagnosis factors among experts, which are important to diagnose Sasang constitution. 2. Methods : We suggested each 100 cases containing body shape, face, temperament, physiological and pathological symptom and constitutional drug response to 2 groups experts, and researched expert opinions. We analyzed concordance coefficient with Kendall's coefficient of concordance W. 3. Results : 1) Experts agreed with 167(82.5%) diagnosis results of cases, but there were 33 cases(17.5%), with which even one expert disagreed 2) The concordance of priority order of Sasang constitutional factors was significantly associated within expert. 3) Experts put the priority concordance to drug response and Face, body shape, voice and Pathological and physiological symptoms in order. 4) In case by case, concordance coefficient was 47(55.9%) in group 1, 9(10.8%) in group 2, 56 (33.5%) in total. 4. Conclusions : Experts made much account of drug responses and faces in diagnosing Sasang constitution. but there were different opinions in concordance coefficient. So Sasang Constitution Diagnosis Guideline is necessary to integrate experts opinions.

1. Objectives: We report the relation between the questionnaire and the health state on the Sasang Constitution. 2. Methods: We carried out a clinical test, in which 2 Oriental medical doctors participated to diagnose health state in each Sasang Constitution with 239 subjects. The subjects were divided into 3 subgroups, which are allocated to healthy group, poor health group and disease group. 3. Results: We extracted 4 questions for Taeeumin, 5 questions for Soyangin and 3 questions for Soeumin from the whole 98 questions respectively. Soyangin and Taeeumin share a same question that shows significant difference by health status. For the statistical analysis, we used a Chi-square test. As a result, we found out that Taeeumin showed different distributions of answers in direct/indirect characteristic, perspiration, frequent urination, regular defecation. According to the health status Soyangin showed the different distribution of the answers in color of urination, frequent urination, mouth dryness, abnormal perspiration, discomfort of head. Soeumin showed the different distribution of the answers in cold and chilly feel of abdomen, digestion status and cause of digestion problems when body condition gets worse. 4. Conclusions: This is the first work which reports the relatedness between Questionnaire and Health State in each Sasang Constitutions by an objective clinical test. We found out that several questions have different distributions by health status in each Sasang Constitution. These extracted questions are categorized not only by Wansilmoobyung(완실무병), but also by other symptoms and body status.

Objectives In Sasang Constitutional medicine(SCM), it is an important factor to assess the degree of cold/heat and healthy status. We purposed to check the agreement among the experts on the assessment of cold/heat and healthy status. Methods Six SCM experts and 10 healthy volunteers were recruited for this study. The SCM experts had an interviewed with each volunteer in the similar condition like that of the actual clinic. And then the expert evaluated each volunteer's cold/heat and healthy status. Intraclass correlation coefficient(ICC) was used to measure the interrater reliability and interrater agreement among the experts. Results Two volunteers are excluded due to the missing data, therefore eight persons' data (3 males and 5 females) were included in our analysis. The mean of age and BMI are 21.73(${\pm}2.32$) and 29.63(${\pm}4.66$), respectively. In health status, cold status and heat status, the ICC was 0.789, 0.904, 0.925, respectively. Conclusions We found that the assessment of cold/heat and healthy status was continued reliable among SCM experts. The assessment of cold/heat status was more consistent than the assessment of healthy status.
