Sasang constitution experts utilize voice characteristics as an auxiliary measure for deciding a person's constitutional group. This study aims at establishing a relationship between speech features and the constitutional groups by subjective listening evaluation of voice characteristics. A speech database of 841 speakers whose constitutional groups have been already diagnosed by Sasang constitution experts was constructed. Speech features related to speech source and vocal tract filter were extracted from five vowels and one sentence. Statistically significant speech features for classifying the groups were analyzed using SPSS. The features contributed to constitution classification were speaking rate, Energy, A1, A2, A3, H1, H2, H4, CPP for males in their 20s, F0_mean, CPP, SPI, HNR, Shimmer, Energy, A1, A2, A3, H1, H2, H4 for females in their 20s, Energy, A1, A2, A3, H1, H2, H4, CPP for male in the 60s, and Jitter, HNR, CPP, SPI for females in their 60s. Experimental results show that speech technology is useful in classifying constitutional groups.

Objectives This study was aimed to compare effects of Yukgunja-tang (YGJT) extract granule on functional dyspepsia (FD) by sasang constitution. Methods A placebo-controlled, double-blind, randomized, two-center trial was performed. We obtained 3D face images of FD patients participating in this study using face-only scanner and classified them into two types as narrow face and wide face by 3D facial shape diagnosis system (3-FSDS). 96 subjects (48 subjects per type) were enrolled and were randomly allocated into treatment or control groups in a 2:1 ratio. YGJT extract granule or placebo were administered to each group during the 8 week treatment period. One of sasang constitutional specialist diagnosed their constitutions by referring to questionnaires and 3D face images. The primary outcome was total dyspepsia symptom scale (TDS scale), the secondary outcomes were single dyspepsia symptom scale (SDS scale), visual analog scale (VAS) and so on. This trial was registered with clinical research information service identifier: KCT0001920, 15 May, 2016. Results In the Taeeumin treatment group, the TDS scale was significantly decreased after 8 weeks compared to the control group (t=2.331, p=0.025) and the SDS scale also significantly decreased. (t=2.042, p=0.048). The specific effects of the YGJT extract granule without the placebo effect on the Taeeumin with functional dyspepsia were 30.61% in TDS scale and 28.33% in SDS scale. Conclusions The effects of Yukgunja-tang extract granule on functional dyspepsia was different according to Sasang constitution. So the constitution should be considered in randomized controlled trials using herbal extract granules.

Objectives: The purpose of this study was to investigate the psychological characteristics of the Sasang constitutions by using Braverman nature assessment (BNA). Methods: One hundred seventy-four students participated in this study, and among them, the 142 individuals who had clearly identified Sasang constitutional types were used for the analysis. Sasang constitutions and the Braverman temperaments of the subjects were determined by using a questionnaire for the Sasang constitution classification (QSCC) II and BNA, respectively. Body mass index (BMI) was used to compare the inclinations of the Sasang constitutions and Braverman temperament types. Results: Significant differences in Braverman temperament type existed among the Sasang constitutions (P = 0.042), and the relations between Soyangin and the dopamine type and between Taeeumin and the gamma-aminobutyric acid (GABA) type were meaningful. Significant differences were also shown in the comparison with the Yin and the Yang constitutions (P = 0.017), and the post-hoc analysis showed a strong and significant relation between the Yang constitution and the dopamine type and between the Yin constitution and the GABA type. The one-way analysis of variance (ANOVA) and the independent t-test were conducted to examine the BMI and the degree of obesity among the Sasang constitutions and the Braverman temperament types. Concerning the BMI, Taeeumin showed a bigger BMI than the other constitutions (P < 0.001), but no significant differences in the BMI were observed between the Braverman temperament types. Conclusion: Soyangin has a close relationship to the dopamine type and Taeeumin has a close relationship to the GABA type. The correlation between two types were more clear when the Yin and the Yang types were compared to Braverman temperaments. These results may serve as a basis for identifying the psychological traits of Sasang constitutional types, especially in regard to the characteristics related to the four Braverman temperament types.

The purpose of this study is to find a classification method with high accuracy in regard with sasang constitutional diagnosis. The BMI, blood pressure, pulse wave, and Sasang constitution diagnosed by a specialist was collected from 2848 subjects who were apparently healthy. Through a selective procedure, the data of 1635 subjects was used in the analysis. The results with the classification methods such as the discriminant analysis, regression, decision tree and neural network were compared with the diagnosis of a Sasang constitutional specialist. In result, the discriminant analysis method was hard to qualify the assumption of the equality of covariance matrices within constitutional groups. Moreover, without BMI, the decision tree and neural network methods were very sensitive to the change of the analysis data. Therefore, the Logistic regression and the decision tree is recommended on condition that the decisive factors of constitution are well concerned.

Objectives The purpose of this study was to investigate the ordinary symptoms, special symptoms and Body Mass Index (BMI) according to Sasang constitution in female college students. Also, we aimed to analyze the factors affecting BMI. Methods Forty-four female college students participated in this study. Sasang Constitution was determined by Questionnaire for Sasang Constitution Classification (QSCC) II. BMI was measured and ordinary symptoms were acqired through the questionnaire. Special symptoms was determined by Fatigue Severity Index (FSS), Premenstrual Symptom Screening Tool (PSST), ROME III, Ocular Surface Disease Index (OSDI), respectively. For statistical analysis, t-test, analysis of variance and correlation test has been used. Results There existed significant differences in ordinary symptoms and special symptoms between sasang constitutions. Taeumin had higher urine frequency than soyangin, soeumin had higher gap of feces than taeumin. Taeumin had higher BMI and ROME III score than soyangin and soeumin. They showed significant differences in ordinary symptoms and special symptoms according to BMI. Overweight and obese group is higher in water intake than low and normal group. Low weight and normal group is higher in gap of feces than overweight and obese group. High score group in PSST and ROME III showed high BMI than low score group. We analyzed the factors that affect BMI. BMI are highly correlated with systolic and diastolic blood pressure. Also, FSS, PSST, ROME III and OSDI showed high correlation with each other. Conclusion Urine frequency and gap of feces are different among sasang constitutional types. The obese group and normal group showed significant differences in water intake, gap of feces, PSST and ROME III score. It is found that factors that affecting BMI are systolic and diastolic blood pressure. These results may lead to identifying the causes and factors of obesity in female college students related to Sasang constitution.

This study was prepared to investigate the correlation between Sasang constitutional groups and voice characteristics using voice analysis system(in this study, CSL). I focused on the voice characteristics in terms of harmonics, Formant frequency and Formant Bandwidth. The subjects were 71 males. I classified them into three groups, that is Soeumin group, Soyangin group and Taeumin group. The classification method of Constitution used two ways, QSCCII(Questionnarie for the Sasang Constitution Classification II) and Interview with a specialist in Sasang Constitution. So 71 people were categorized into 31 Soeumin(people), 18 Soyangin(people) and 22 Taeumin(people). Pitch is approximately similar to the fundamental frequency(F0) in voices. Shimmer in dB gives an evaluation of the period-to-period variability of the peak-to-peak amplitude within the analyzed voice sample. FFT(Fast Fourier Transform) method in CSL can display sampled voices into harmonics. H1 is the first peak and h2 is the second peak in the harmonics. The amplitude difference of h1 and h2(h1-h2) can be explained as the speaker's phonation type, And Formant frequency and bandwidth can be explained as the speaker's vocal tract. So I checked the harmonics and Formant frequency and Bandwidth as the voice parameters. First I have captured /e/ voices from all subjects using microphone. And then I analyzed /e/ voices with CSL. Power Spectrum and Formant History is the menu in the CSL which can display harmonics and Formant frequency and bandwidth. The results about the correlation between Sasang Constitutional Groups and voice parameters are as follows; 1. There is no significant amplitude difference of harmonics(h1-h2) among three groups. 2. There is the significant difference between Soeumin Group and Soyangin Group in Formant Frequency 1 and Formant Bandwidth 1(p<0.05). Any other parameters have no significance. I assume that Soyangin Group has clearer and brighter voice than Soeumin Group according to the Formant Bandwidth difference. And I think its result has coincidence with the context of "Dongyi Suse Bowon" and "Sasangimhejinam".

Background : Sasang Constitutional Medicine (SCM) is the field of traditional Korean medicine that emphasize four constitutional types for diagnosis and treatment. Appearance, personalities and pathological characteristics are main factors of Sasang constitutional classification. Previous studies carried out by the pulse analyzer showed that the pulse wave can discriminate these types. In addition, It was reported that the pulse wave are affected by age and sexuality. In this study, we investigated the pulse wave characteristics related Sasang constitution types in control group regarding their age and sexuality. Subjects and Method : Two hudred and eighteen volunteers participated in this study: healthy men in $20{\sim}49$ years old. Participants were interviewed and examined to evaluate their health condition and Sasang constitution type. Then they were tested with pulse analyzer when they ere stabilized. The pulse at the radial artery just beside styloid process was measured, because this area is landmark for pulse diagnosis in oriental medicine. 3-D Mac pulse analyzer (Daeyo Medi Co. Ansan. Korea) was used in this study. We analyzed main features of pulse waves with the Sasang condtitution types by the SPSS for Windows (ver 12.0). Results : There was significant difference between Taeum and other types in contact pressure as weil as in coefficient of floating and sinking pulse. Conclusion : By analyzing pulse waves of healthy adult men. we found significant differences exist between Taeum and other types. These pulse differences may characterize Taeum type, and it will be helpful for the evaluation of Taeum type.

The Sasang constitution typology was analyzed through SCAT2 and a specialist to examine the correlation between the Sasang constitution and dietary pattern, and the difference in BMI and food preference according to Sasang constitution was determined. The Sasang constitution typology of the subjects was classified by SCAT2 and a specialist. Seventy-four subjects were screened by SCAT2 (SC), and 18 of them were judged by the specialist (SP). The results of SCAT2 and the specialist were consistent in 13 subjects (SS). BMI and food preference among these groups were compared. The concordance rate of SCAT2 and the specialist classification was 72.2%. The BMI in SC was significantly lower in the order of Taeeumin, Soyangin, and Soeumin, but no significant difference was observed between Taeeumin and Soyangin in SP and SS. To analyze the preference of food and the constitutional suitability, the 'Yin-Yang food preference index' was developed and compared with the data classified by constitutional food according to existing ideological medical theory. As a result, there were 33 food items that matched in the SP-SS, which was more than that in the SC-SP (4 items), SC-SS (6 items), and SC-SP-SS (4 items). Twenty-four of the 33 matched food items were consistent with the existing constitutional food data. In conclusion, SCAT2 is a very useful tool for Sasang constitutional research, but for more objective research, it is recommended that subjects who show consistent results by different methods be targeted.
