1. Objectives This study was to designed investigate the relationship between hypertension and its risk factors and the prevalence of hypertension according to Sasang Constitution. 2. Methods Five hundred and twenty six people were subjects out of 666 people, over 40 years old, who participated in the community-based cohort in Wonju, South Korea from July 2nd to August 30th in 2006. Hypertensive group was 263 peoples and normal group was 263 people, selected randomly among non hypertensive people who had same age and sex with hypertensive groups. Sasang Constitutional Diagnosis was carried out using PSSC(Phonetic System of Sasang Constitution), face and tongue photos and a checkup list. Risk factors from blood samples, physical measurements and social indices were analyzed using SPSS. 3. Results The prevalence of hypertension in Taeeumin was 63.1%(N=166), that of Soeumin was 22.4%(N=59) and that of Soyangin was 14.4%(N= 38). Considering risk factors of hypertension, there weren't any differences between two groups in social support indices and Framingham type A score. But scores of Soeumin's and Soyangin's were significantly high compared with that of Taeeumin in female normal group. There were significantly high results in Adiponectin of Soeumin's and HDL-cholesterol of female Soyangin's and HOMA-IR of Taeeumin's than any other groups. Crude OR of Taeeumin was 2.18 as compared with that of Soeumin in terms of risk of hypertension, and OR of Taeeumin was 2.02 as compared with that of Soeumin after drinking, smoking, total cholesterol, fasting blood sugar and HOMA-IR were adjusted. But after BMI was adjusted there wasn't a significance between Soeumin and Taeeumin and the OR of more than 25 was 2.42 as compared with that of less than 23 in BMI. 4. Conclusions Sasang Constitution is thought to be the reasonable variable to control hypertension in terms of prevention, treatment and regimen. And constitution is needed as a good variable to make a cohort study concerning chronic diseases, especially hypertension.

Objectives Recently, Sasang Constitutional Analysis Tool (SCAT) was developed using face, body shape, questionnaire, and voice information. The purpose of this paper is to analysis the characteristics of SCAT in detail for the subjects whose Sasang Constitutional (SC) type was confirmed clearly. Methods 1) The SC types of 108 patients were diagnosed by an expert of Sasang constitutional medicine through the observation of improvements after taking more than 20 packs of herbal medicine prescribed 2) The diagnostic results of SCAT were acquired for the patients. 3) Comparison between diagnostic results of the SCAT and expert was performed according to SC probability difference, the number of packs of herbal medicine prescribed, the number of hospital visits, and age. Results 1) The concordance rate was 65.9% and 59.4% in the male and female groups, respectively. 2) Overall, the concordance rate increased as the SC probability difference increased. In case of more than 5% SC probability difference, it increased up to 71.0% and 66.7% in the male and female groups, respectively. 3) The concordance rate did not show any trend as the number of packs of herbal medicine prescribed and the number of hospital visits increased. 4) The higher concordance rate was observed in Taeeumin, Soyangin, and 20s ~ 40s groups of male patients, and in Soyangin, 20s, and 40s groups of female patients. Conclusions The strong and weak points of SCAT were observed and they will contribute to the improvement of SCAT performance.

Since Traditional Korean medicine (TKM) doctors use various knowledge systems during treatment, diagnosis results may differ for each TKM doctor. However, it is difficult to explain all the reasons for the diagnosis because TKM doctors use both explicit and implicit knowledge. In this study, an upgraded random forest (RF)-based evaluation tool was proposed to extract clinical knowledge of TKM doctors. Also, it was confirmed to what extent the professor's clinical knowledge was delivered to the trainees by using the evaluation tool. The data used to construct the evaluation tool were targeted at 106 people who visited the Sasang Constitutional Department at Kyung Hee University Korean Medicine Hospital at Gangdong. For explicit knowledge extraction, four TKM doctors were asked to express the importance of symptoms as scores. In addition, for implicit knowledge extraction, importance score was confirmed in the RF model that learned the patient's symptoms and the TKM doctor's constitutional determination results. In order to confirm the delivery of clinical knowledge, the similarity of symptoms that professors and trainees consider important when discriminating constitution was calculated using the Jaccard coefficient. As a result of the study, our proposed tool was able to successfully evaluate the clinical knowledge of TKM doctors. Also, it was confirmed that the professor's clinical knowledge was delivered to the trainee. Our tool can be used in various fields such as providing feedback on treatment, education of training TKM doctors, and development of AI in TKM.

1. Objectives The purpose of this study lies on the objectification of the Sasang Constitutional diagnosis. This study was analyzing the constitutional characteristic of adult men voices by PSSC-2004. 2. Methods The study was conducted on the subjects inputted /a/ 2.5-3 sec of 231 adult men voices to PSSC-2004. The statistical analyses are applied to three groups: total group, under 55 year-old group, over 55 year-old group. The group of total 231 was composed with 5 Taeyangins, 32 Soyangins, 102 Taeumins and 92 Soeumins. The under 55 years old group was composed with 4 Taeyangins, 23 Soyangins, 83 Taeumins and 77 Soeumins. The over 55 year-old group was composed with 1 Taeyangin, 9 Soyangins, 19 Taeumins and 15 Soeumins. 3. Results 1) In total group, the Soeumin's mean value of center pitch(4)$(1,000{\sim}2,000Hz)$ was significantly high compared with the others (P=0.034). 2) In total group, the Soeumin's group 3 APQ was significantly low compared with the others (P=0.042). 3) In under 55 year-old group, the Soeumin's center value of center pitch 4$(1,000{\sim}2,000Hz)$ was significantly high compared with the others (P=0.025) 4) In over 55 year-old group, no statistical significance was found between the Taeyangin, Soyangin, Taeumin and Soeumin. 4. Conclusions In under 55 year-old group, Soeumin's voice showed high pitched sound (clearness) at the low frequency (1000-2000Hz). In over 55 year-old group, there is no significant differences. This fits in with that 'Soeumin's voice is 'Yu-tone' born by 'Shang-tone', very short and high.' 'Yu-tone' corresponds to 'Ra' and witch is highest among Gong, Shang, Gao, Chi and Yu. This is related with the appearance that the Soeumin's voice is weak, thin and high tone. Therefore it is supposed that Soeumin adult men's voices are thick, and there are vibrations of the ending. It is accepted one of the Soeumin's characters like as a mild tremor of limbs and deep breath caused by Soeumin's Qi-deficiency. This outcome accords with the theory that Soeumin's Qi is less than the Other constitutions.

Sasang Constitutional Medicine focuses on the different constitutional manifestations of the individual's nature and emotions. The nature and emotions drive the ascending and descending of Qi in the body. And this dynamics of the Qi's ascent and descent shapes the different types of structures, functions and temperaments. Although Sasang Constitutional Medicine has many advantages, its diagnosis of the constitution still depends on the doctors' own idea and has no objective identification. So many doctors in Korea have been trying to solve this problem. Recently, there are several efforts to find out the relationship between genetic information and constitution. By the way, May, 1998 there is a astonishing report about the gene which determines the human performance, that is ACE(angiotensin converting enzyme). And it suggests that the I allele was associated with improved endurance performance. ACE has three genotype including II, ID and DD. "I" means insertion and "D" means deletion. We determined the type of the Sasang constitution with QSCCII questionaire and the one's ACE genotype with PCR of the 127 people and we discovered the relationship between the constitution and the ACE genotype. The result is as follow. Among 39 people who have the II genotype, 7(18%) belong to Taeum(Taiyin), 9(23.1%) belong to Soyang(Shaoyang) and 23(59%) belong to Soeum(Shaoyin). Among 62 people who have the ID genotype, 18(29%) belong to Taeum(Taiyin), 21(33.9%) belong to Soyang(Shaoyang) and 23(37.1%) belong to Soeum(Shaoyin). Among 26 people who have DD genotype, 11(42.3%) belong to Taeum(Taiyin), 4(15.4%) belong to Soyang(Shaoyang) and 11(42.3%) belong to Soeum(Shaoyin). This data indicates that there are implicable relationship between the Sasang constitution and ACE genotype. Especially people who have II genotype have much possibility to be a Soeum(Shaoyin) person (59%) and Soyang(Shaoyang) person have less possibility to have DD genotype (15.4%). With this conclusion, we suggest further study of relationship between the Sasang constitution and ACE genotype and we think that other polymorphism can be a candidate of the partner of Sasang constitution.

Objectives This study aimed to evaluate reliability of questionnaire when self reporting questionnaire created by Korea Institute of Oriental Medicine was applied to Vietnamese. Methods This study began to collect 135 Vietnamese patients questionnaires collaborated with National Hospital of Traditional Medicine located in Hanoi, Vietnam from March to August 2013. All participants for this study filled out the questionnaires respectively. After initial survey finished, additional survey was performed on the same questionnaires used at the beginning eight weeks later. In order to evaluate internal coherence in terms of questionnaires of classification, Cronbach's alpha and Cohen's kappa was measured. Results After analysis of 78 questions collected, less than 0.4 in Kappa was achieved by 21(26.9%) out of 78 questions, 0.4 to 0.75 Kappa by 49(62.8%) and 0.75 over in 5(6.5%) questions, respectively. More than 0.6 Cronbach's alpha was defined from 41 out of 78 questions connected with internal coherence of character, digestion, perspiration, excrement, urine, cold and heat. Conclusions The questionnaire has credibility according to values of Kappa and Cronbach's alpha. Therefore, Sasang Constitution questionnaire can be applied to Sasang Diagnosis. In order to increase usefulness, questions in questionnaire should be revised and validity study must be performed afterwards.

Objectives: The purpose of this studay was to compare the eating-related index and the patterns of pre- and post-prandial gut hormone level in normal-overweight and obese subjects of Taeemin population. Methods: We enrolled healthy male participants who were diagnosed with Taeeumin by Sasang Constitutional diagnosis and who were normal-overweight ($18.5kg/m^2{\leq}$body mass index [BMI)< $25kg/m^2$) or obese ($25.0kg/m^2{\leq}$BMI< $30kg/m^2$). Eating behavior and gastrointestinal problems were assessed by using standardized scale. Subjective appetite ratings using visual analogue scales and the profiling of serum levels of ghrelin and peptide YY (PYY) were assessed before and after a standard meal (6 time points: 30 minutes pre-prandial, immediately before meal, 15, 30, 60, and 120 minutes post-prandial). Results: Tewnty two healthy Taeeumin people classified as normal-overweight group or obese group are the final subjects. External eating score of Dutch eating behavior questionaire scores is higher in normal-overweight group than in obese group. The variations of subjective appetite ratings in obese group are smaller than in normal-overweight group. The pattern of ghrelin in normal-overweight group shows a high peak at 30 minutes post-prandial point, which is contrary to existing studies. The pattern of PYY in obese group decreases from 15 minutes post-prandial point and shows lower peak level, whereas in normal-overweight group shows increasing tendency from pre-prandial point until 30 minutes post-prandial point. Conclusions: There are differences in the eating-related index and the gut hormone patterns related to obesity.

Objective : This research was conducted to evaluate the method of sasangin classification by voice analysis, The 2 pilot tests were thus designed to solve the following problems: 'What are the conditions at classification for sasangin by the voice analysis?' and 'What are the important variances of /a/ parameter?'. Methods: 122 volunteers Were examined to make a diagnosis of sasangin by QSCC II and they were disease-free and healthy, First, they said /a/ three times for 2 seconds in their usual voice, Second, they said /a/ for 2 seconds by the different ways of high tone, mid tone, and low tone. The sounds were collected by a recording program (cooledit 2000) through a Sony microphone (ecm-26l). We analyzed the voices by maltlab, the simulation tool. Results: There were no differences and were correlations when one said /a/ three times for 2 seconds in the usual voice. There were some things to correlate when one said /a/ three times for 2 seconds by the different ways of high speech, usual speech, and low speech. Others were nothing to correlate. We evaluated the value of sasangin classification method by only /a/ voice analysis. The hit ratio was average $66.3\%\;:\;soyangin\;67.9\%,\;taeumin\;68.0\%,\;soeumin\;63.9\%$. Conclusion: We must set up the conditions to use the method of sasangin classification by voice analysis. The value of sasangin classification method by only fa! voice analysis was a hit ratio of $66.3\%$.

Objectives The aim of this study is to develop a Korea Sasang Constitutional Diagnostic Questionnaire (KS-15) with practicality and validity. Methods The data of body shape, temperament and symptoms were collected from 11 nationwide multi-centers in Korean Medical Clinics between Nov. 2009 to Aug. 2012. KS-15 algorithm was developed through Multinomial Logistic Regression and was applied for test group to verify it's classificatory function. Results The weight value of variables of KS-15 were different between male and female. The concordance of KS-15 with the expert in training group was 58.34% (72.8% in Tae-eumin, 54.8% in Soeumin, and 44.1% in Soyangin). The concordance of KS-15 with the expert in test group was 63.1% (63% in Tae-eumin, 83.3% in Soeumin, and 51.9% in Soyangin). Conclusions KS-15 seems to have suitable implement with practicality and validity. Further study is necessary to verify it accuracy and cut-off.
