Purpose : The purpose of this study was to investigate menstrual symptoms and patterns of high school girls by Sasang constitution and relationship between such symptoms and Sasang constitution. Methods : For the study, QSCCII and 'M.B.Q' employed to analyze the data collected from 581 high school girls in Pusan from July 11 to July 20, 2006. Results : As for menstrual characteristics of the subjects by Sasang constitution Taeeumins start menarche is relatively early in contrast with Soeumins who experienced menarche relatively late(P=.012). This survey proves that menses last relatively long for Soeumin whereas Soyangins have relatively short period of menstruation(P=.043). Furthermore, Taeeumins account for majority of those who have much quantity of menstruation with 22.7% while Soeumins account for majority with 13.2%. From the analysis into menstrual symptoms of the subjects put under 5 categories of Sasang constitution, it became evident that Soeumins turned out to have most negative affect(11.8${\pm}$3.78) (P=.053). Soeumins scored the highest points in the response area of autonomic reactions(10.6${\pm}$3.24)(P=.014). In the total points of menstrual symptoms including the above 5 sub-categories, Soeumins recorded the highest scores(52.4${\pm}$12.5), followed by Soyangins(50.0${\pm}$12.2) and Taeeumins in order, showing that there is no statistically significant difference(F = 2.859, p = .058) among them although Soeumins seem to feel slightly more menstrual symptoms than Soyangins and Taeeumins. Conclusion : We hope these results could be helpful to diagnosis and treatment of mestrual diseases.

Objectives: The purpose of this study is to find out the health condition and the etiology in oriental medicine of the high school girls menstrual disorders by Sasang constitution. Methods: The data from the 795 participants were collected using a structured menstrual history questionnaire. Based on the survey responses, we had 97 adolescents with menstrual disorder as the test group and 97 adolescents without menstrual disorder as the control group. The clinical trials subjects were asked to respond to another questionnaire for identifying their constitutional types and respond to the DSOM and undergo Inbody. We identified significant variables for dysmenorrhea from comparison between the test and control group. Results: The DSOM test showed that the scores of qi stagnation, static blood, cold, dampness, phlegm, heart, kidney were significantly higher in dysmenorrhea, scant menstruation, menstruation at irregular intervals. For the Sasang constitution, there is a difference on the cause of the outbreak. Soyangin from yin deficiency, dryness and blood deficiency is associated with menstrual disorders. Taeumin from cold, dampness and qi deficiency is associated with menstrual disorders. Soeumin from heart, qi stagnation, static blood and spleen is associated with menstrual disorders. Conclusions: For the Sasang constitution, there is a difference on the cause of the outbreak. The result of a comparison of the test and control groups showed that there's no relevance to the body fat mass and body fat percentage with menstrual irregularities.

Objectives: This study aimed to reveal the gait characteristics of each Sasang constitution by examining the differences in gait analysis indicators using a 3-axis accelerometer. Methods: Ninety-one participants were classified through the TS-QSCD (Two-Step Questionnaire for Sasang Constitution Diagnosis) method and gait analysis was performed using a 3-Axis Accelerometer (G-WALK. BTS Bioengineering, Italy). Gait analysis in returning to the 6-meter turnaround point and 6-minute walking test were performed. The differences in the gait analysis index values were analyzed between each constitution. Results: The gait analysis of 91 subjects (37 Taeumin, 37 Soyangin, and 17 Soeumin), showed that the percent stride length/height in the Soyangin subjects was significantly higher than that of the Taeeumin and Soeuminin subjects in the spatiotemporal walking variables (p<0.05). Stride length also showed the widest tendency in the Soyangin subjects (p=0.05). In the kinesiological analysis, the range of pelvic obliquity angles in the Soeumin subjects was significantly wider than that of the Taeumin and Soyangin subjects (p<0.05). In the six-minute walking test, the Soyangin subjects walked the farthest at 309.41±35.23 m (p=0.064). Conclusions: In a comparison of the gait characteristics for each Sasang constitution using a three-dimensional accelerometer, the stride width of the Soyangin subjects was the widest compared to the Taeeumin, and Soeumin subjects, and Soyangin's walking speed showed a faster tendency than that of the Taeeumin and Soeumin subjects.

In this paper, the O-Ring Measurement System (O-R MS) has been designed to supplement such subectivity and apply to the diagnosis by constitution. A single chip microprocessor of Intel MCS-51 family has been used to control the O-R MS and process data with real time, and the O-R MS could measure the minute muscular strength, expanded width between fingers, and time of the measurement. Therefore the objective constitutional diagnosis is possible by the O-R MS. As a clinical testing for estimating credibility of O-R MS, the acupuncture points representing the constitution has been stimulated using a semiconductor laser stimulator and measure the muscular strength by the O-R MS. The result of clinical testing has been shown that the constitutional diagnosis with the O-R MS is proved highly precision of 96% and it is expected that the O-R MS can be used practically for the objective constitutional diagnosis.

1. Objectives The purpose of this study was to investigate the concordance rate of the diagnostic results among Sasang Constitutional Medicine(SCM) specialists. 2. Methods We carried out two studies in order to investigate the concordance rate of the diagnostic results between SCM specialists. We calculated the kappa value for analyzing concordance rate(using the SPSS program). 1) Study A : We investigated 142 clients who had taken health examinations and diagnosis of Sasang constitution from March 9, 2005 to March 29, 2005 at a health examination center of Kyung-Hee medical center. Every SCM specialist diagnosed 142 clients directly. Each SCM specialist don’t know the other specialist’s diagnosis. 2) Study B : We investigated 176 clients who had taken health examinations and diagnosis of Sasang constitution from January 2005 to March 2005 at the department of Occupational and Environmental medicine of Kyung-Hee medical center. One SCM specialist diagnosed 176 clients directly and the other specialist knowing previous specialist’s diagnosis, diagnosed each person indirectly 3. Results 1) The concordance rate of the diagnostic results among SCM specialists in study A was relatively high(kappa value=0.700). 2) The concordance rate of the diagnostic results among SCM specialists in study B was high(kappa value=0.895). 4. Conclusions We can confirm the concordance rate of the diagnostic results among SCM specialists is relatively high.

Objectives: We analyzed Sasang constitution case reports using text mining to derive network analysis results and designed a classification algorithm using machine learning to select a model suitable for classifying Sasang constitution based on text data. Methods: Case reports on Sasang constitution published from January 1, 2000, to December 31, 2022, were searched. As a result, 343 papers were selected, yielding 454 cases. Extracted texts were pretreated and tokenized with the Python-based KoNLPy package. Each morpheme was vectorized using TF-IDF values. Word cloud visualization and centrality analysis identified keywords mainly used for classifying Sasang constitution in clinical practice. To select the most suitable classification model for diagnosing Sasang constitution, the performance of five models-XGBoost, LightGBM, SVC, Logistic Regression, and Random Forest Classifier-was evaluated using accuracy and F1-Score. Results: Through word cloud visualization and centrality analysis, specific keywords for each constitution were identified. Logistic regression showed the highest accuracy (0.839416), while random forest classifier showed the lowest (0.773723). Based on F1-Score, XGBoost scored the highest (0.739811), and random forest classifier scored the lowest (0.643421). Conclusions: This is the first study to analyze constitution classification by applying text mining and machine learning to case reports, providing a concrete research model for follow-up research. The keywords selected through text mining were confirmed to effectively reflect the characteristics of each Sasang constitution type. Based on text data from case reports, the most suitable machine learning models for diagnosing Sasang constitution are logistic regression and XGBoost.
