Objective The Constitutional Seong-Jeong therapy is one of the important ways to prevent Sasang constitutional symptomatology. But, there are various interpretations and unclear aspects of the content and meaning, so there are many difficulties in applying it concretely in actual clinical practice. The purpose of this study is to clarify the physiology, pathology, treatment mechanism and its specific meaning. Method The pathology associated with constitutional symptomatology is known as Deepening-Seong and Exploding-Jeong. Therefore, related pathologies and corresponding treatment and prevention mechanisms were reviewed, focusing on the related contents of Donguisusebowon, and their specific meanings were considered. Results and Conclusions 1. Constitutional Seong-Jeong therapy is a regimen to prevent and manage Deepening-Seong and Exploding-Jeong. 2. Deepening-Seong and Exploding-Jeong are the inappropriate occurrences of Seong and Jeong in the poor area of the Heavenly-frame recognition and in the vulnerable area of Humanly-activity practice, and the antecedent cause is covetous desire. 3. Deepening-Seong and Exploding-Jeong cause the weakening in the power of ears-eyes-nose-mouth to perceive Heavenly frame and the power of lung-spleen-liver-kidney to practice Humanly activity in the four constitution's weak system, which lead to the Interruption in processing of four Qi in each weak system. 4. The four constitutions must be careful about the occurrence of covetous desire in the process of recognizing Heavenly frame and doing Humanly activity so that intellectual and behavioral abilities can be exerted to overcome the poor area of the recognition of Heavenly frame and the formation of Humanly activity to prevent deepening-Seong and exploding-Jeong from occurring.

Objectives This paper was aimed to review the preceding research on the origins, changes and constructive principle of Mahwangjeongchun-tang. Method Based on Jema Lee's works such as Dongyisusebowon and Dongmuyoogo, we analyzed contents related to Mahwangjeongchun-tang and its modification. Moreover, we reviewed physiological and pathological pecularities of Taeeumin symptomatology and applied the theory to induce the principle of the modified Mahwangjeongchun-tang in Sasang medicine. Results and Conclusion 1) The origins of Mahwangjeongchun-tang might be Mahwang-tang, Jungchun-tang and Saengmaek-san. 2) Mahwangjeongchun-tang had been changed in composition when it moved from Manbyonghoichun to Dongyisusebowon. 3) Mahwangjeongchun-tang consists of a) Platycodi Radix (桔梗), Liriopis Tuber(麥門冬) and Scutellariae Radix(黃芩) which directly or indirectly enhance lung function, b) Ephedra Sinica(麻黃) which affects circulation of lung companion, c) Prunus Armeniaca(杏仁) and Ginkgo Biloba(白果) which affect wiwan's upward circulatory force, d) Radish Seed (蘿葍子) which affects small intestine's digesting effect, e) Mori Cortex Radicis(桑白皮) and Farfarae Flos(款冬花) which affect cough and asthma.

Objectives Sasang constitutional medicine is a traditional Korean medicine that classifies humans into four constitutions in consideration of individual differences in physical, psychological, and physiological characteristics. In this paper, we proposed a method to classify Taeeum person (TE) and Non-Taeeum person (NTE), Soeum person (SE) and Non-Soeum person (NSE), and Soyang person (ST) and Non-Soyang person (NSY) using a convolutional neural network with only facial images. Methods Based on the convolutional neural network VGG16 architecture, transfer learning is carried out on the facial images of 3738 subjects to classify TE and NTE, SE and NSE, and SY and NSY. Data augmentation techniques are used to increase classification performance. Results The classification performance of TE and NTE, SE and NSE, and SY and NSY was 77.24%, 85.17%, and 80.18% by F1 score and 80.02%, 85.96%, and 72.76% by Precision-Recall AUC (Area Under the receiver operating characteristic Curve) respectively. Conclusions It was found that Soeum person had the most heterogeneous facial features as it had the best classification performance compared to the rest of the constitution, followed by Taeeum person and Soyang person. The experimental results showed that there is a possibility to classify constitutions only with facial images. The performance is expected to increase with additional data such as BMI or personality questionnaire.

Background Abdominal obesity, a major public health concern, is related to many health problems. In addition, it is influenced by individual characteristics. We investigated sleep quality and physical activity (PA) as risk factors for abdominal obesity, according to the Sasang constitutional medicine. Methods In this cross-sectional study, we analyzed data from 5,221 community-based participants. Sleep quality and PA were measured using structured questionnaires, and abdominal obesity was classified according to waist circumference. Sasang constitution (SC) was classified as Taeeumin (TE), Soeumin (SE), or Soyangin (SY) type, using an established SC questionnaire. Chi-square test and logistic regression analysis were performed to access the association of sleep quality and PA with abdominal obesity in individuals stratified according to the SC types. Results The percentage of poor sleep quality and inactive PA was the highest in the SE type, and the higher prevalence of abdominal obesity was found in the TE type. After adjusting for variables, inactive PA was associated with abdominal obesity in the TE type (OR=1.694, 95% CI=1.42-2.021), and in the SE type, abdominal obesity was associated with poor sleep quality (OR=1.688, 95% CI=1.091-2.611) and low PA (OR=2.127, 95% CI=1.163-3.89). Moreover, the combination of these two factors were also significantly associated with abdominal obesity in the TE and SE types. Conclusion Abdominal obesity was associated with sleep quality and PA, and these results were different in each SC type. Taking various associated lifestyles and individual characteristics in consideration may contribute to better management of abdominal obesity in clinical practice.

Objectives The purpose of this study is to review the current Sasang constitutional research on obesity and to provide basic data for further development in the direction of better research. Methods Clinical research articles on obesity of the Sasang Constitutional Medicine were extracted from five database. Published year, published journals, and subjects of studies were classified. Clinical methods for the classification of Sasang type and diagnostic criteria for obesity were summarized. Results A total of 36 selected research articles were published from 1998 to 2020. And 20 articles(55.6%) have been published in Journal of Sasang Constitutional Medicine and Journal of Oriental Rehabilitation Medicine. Most of the clinical study subjects were studies that identified independent factors that were correlated with obesity by Sasang constitution type. But these studies have not sufficiently reflected the distinctive characteristics of Sasang Constitution Medicine. Discussion Through this study, it was confirmed to the necessity of developing new research designs for obesity by Sasang constitution and researching on obesity treatment through improvement of symptoms by using the already developed questionnaires that have proven reliability and validity, away from the research biased towards Taeeumin and Taeeumin's prescription. If additional research based on this study is accompanied, it is expected that it can be utilized in typed obesity treatment fields.

A 52-year-old female diagnosed with Atypical Parkinsonian Disorders (APD) about one year ago suffered from dizziness and gait disturbance. The patient was identified as Taeeumin esophagus-cold lung-dry symptomatology pattern and was treated with Jowisengcheong-tang. The patient's symptoms of dizziness and night sweats were assessed using Global Assessment Scale (GAS). And, the Unified Multiple System Atrophy Rating Scale (UMSARS) and the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) were used to assess the overall function of the patient. The patient's symptoms of dizziness and night sweats were significantly improved, and UMSARS and MDS-UPDRS scores were decreased. This case showed that Sasang constitutional medicine treatment can improve APD symptoms and improve the quality of life of the patient.
