Objectives We aimed to characterize the results obtained from Korean medical examinations and questionnaires on the quality of sleep. Methods The quality of sleep was measured using the Pittsburgh sleep quality index in 400 subjects. Afterwards, heart rate variability (HRV) measurements were done, along with the analyses for tongue color, teeth marks, and tongue coating through the tongue diagnosis system. A questionnaire about body's heat, cold and sweating conditions, and the perceived stress scale (PSS) were performed. Finally, correlations between all these indicators and the sleep quality were analyzed. Results As the quality of sleep decreased, the sympathetic nervous system was stimulated. The subjects who had the blue-purple colored tongue experienced decreased quality of sleep. The quality of sleep was also deteriorated in the subjects who usually feel cold and hot easily, sweat a lot, and feel a lot of discomfort. According to the PSS questionnaire, the higher the stress level is, the lower was the quality of sleep. Conclusions We obtained meaningful results by comprehensively analyzing the sleep quality, HRV, tongue diagnosis, heat and cold conditions, sweating, and stress conditions. In particular, the sleep quality had a significant correlation with the rest of the indicators.

A WTCI is an important criteria for evaluating an mount of patient's tongue coating in tongue diagnosis. However, Previous WTCI tongue coating evaluation methods is a most of quantitatively measuring ration of the extracted tongue coating region and tongue body region, which has a non-objective measurement problem occurring by exposure conditions of tongue image or the recognition performance of tongue coating. Therefore, a WTCI based on deep learning is proposed for classifying an amount of tonger coating in this paper. This is applying the AI deep learning method using big data. to WTCI for evaluating an amount of tonger coating. In order to verify the effectiveness performance of the deep learning in tongue coating evaluating method, we classify the 3 types class(no coating, some coating, intense coating) of an amount of tongue coating by using CNN model. As a results by testing a building the tongue coating sample images for learning and verification of CNN model, proposed method is showed 96.7% with respect to the accuracy of classifying an amount of tongue coating.

Alveolar soft-part sarcoma(ASPS) is a rare, aggressive malignancy of uncertain histologic origin with a propensity for vascular invasion and distant metastasis. ASPS may mimic benign vascular neoplams of malformation but careful evaluation of the unique imaging features on CT scans, MR images, and angiograms lead to the correct diagnosis. ASPS of the tongue is slow-growing, painless mass, especially ASPS of the base the tongue is difficult to be noticed by patient, dentists or oral and maxillofacial surgeons on oral examintion because of its location and clinical resemblance to a benign lesion. And it leads to delayed or inadequate diagnosis. We report radiologic and clinical features of an ASPS of the basal portion of the tongue in a 17-year-old boy, showing normal appearance, but palpation of the tongue and floor of the mouth reveals the tumor. Among the 23 cases of a primary ASPS of tongue reported, 7 cases occured on the basal region of the tongue, inculding the present one. There has been no recurrence or metastasis as of 3 years postoperatively.

A new tongue examination model by using color analysis according to the taste division of tongue. The proposed system consists of a tongue image acquisition in a predefined template, taste region segmentation, color distribution analysis and abnormality decision of tongue by color analysis using Hue-Saturation histograms and the part of a mobile application service. We divided 4 basic taste(bitter, sweet, salty and sour) regions and performed color distribution analysis targeting each region under HSI(Hue Saturation Intensity) color model. To minimize the influence of illumination, the histograms of H and S components only except U are utilized. Using the analyzed results, the abnormality is discriminated by the criteria of the histogram range of normal tongues. Finally, a self tongue diagnosis system which can be used anytime and anywhere on mobile environment.

Objectives: We aim to observe the relation of body mass index (BMI) and the indicators of oral health. Methods: 400 subjects participated in the study. The BMI values are calculated from the height and weight. For the tongue diagnosis, we used the tongue imaging device to analyze the color, tongue coating, and tooth marks. We measured the concentration of hydrogen sulfide (H₂S) and methyl mercaptan (CH₃SH) to evaluate the halitosis. The dry mouth was evaluated through the measurement of saliva secretion and with the questionnaire asking the frequency of dry mouth. Results: The BMI values were significantly higher in the group with light-white and blue-purple colored tongue, and significantly lower for lightly-coated tongue. However, the correlation of BMI and the amounts of saliva secretion was not significant as well as in the correlation of BMI and the concentration of H₂S, CH₃SH. In tongue diagnosis, the subjects who had blue-purple colored tongue also had significantly higher H₂S and CH₃SH, but tendency of lower saliva secretion. Conclusion: We obtain data showing that BMI value and the indicators of oral health including tongue diagnosis have meaningful correlation.

In order to the excellent differentiation of syndromes, we study on the individual characteristic factor by the inspection of face colour and tongue & the auscultation and olfaction. To the subject of diagnosis special books and diagnostics textbook of korean medicine, we arrange the individual characteristic factor by the inspection of face colour and tongue & the auscultation and olfaction. The inspection on the individual characteristic factor was analyzed the face colour, inspection of tongue. The auscultation and olfaction on the individual characteristic factor was analyzed the 25 types by the five-voice (五音) in Huang Di Nei Jing (黃帝內經). As the results, the individual characteristic factor is very important item of the four methods of diagnosis and the differentiation of syndromes. And Therefore the process on four methods of diagnosis and differentiation of syndromesis is necessary to divide the signs of individual characteristic factor and the signs of disease.

1. Objectives and Methods This study was performed to know the relationship between Sasang Constitution and characteristics of ordinary symptoms, inspection diagnosis of face and tongue. There were 666 participants(280 men and 386 women) who answered Sasang Constitutional Checkup list and were taken pictures of faces and tongues. Sasang Constitution was diagnosed by only PSSC(Phonetic System for Sasang Constitution). Distribution of Sasang Constitution and X2 test, kappa value for agreement were calculated using SPSS 10.0. 2. Results From characteristics of ordinary symptoms' point of view, Taeeumin had loud voices, big body shapes and easily sweated themselves. They felt good after sweating and had warm hands and feet. And their upper back, shoulders and chest were, they thought, well developed. They were apt to have meals quickly and overeat themselves. Soyangin and Soeumin had thin body shapes and were difficult to sweat themselves and felt powerless after sweating. They had cold hands and feet. Especially, Soeumin was apt to have meals slowly and a little amounts. They walked so fast. Soyangin was introvert and had developed their abdomen and waist. 'Looking heavy and steady' was higher in Taeeumin, 'delicate and modest' was higher in Soeumin(42.8%) and Soyangin(36.1 %) in first impression. It was thought to be difficult to discriminate Soyangin from Soeumin in first impression and make a notion of right Soyangin's first impression. Soyangin had pinky tongue color and little tongue fur whereas Soeumin had red tongue color and whitish tongue fur. Taeeumin had whitish tongue fur too. 3. Conclusions To diagnose Sasang Constitution much effectively, PSSC results and comprehensive Sasang Constitutional Checkup list extracted from effective Questionnaire items and Face and Tongue Inspection Diagnosis are thought to be needed.

Tongue diagnosis is convenient and non-invasive method to examine the body's functional condition, and it has been frequently used in traditional Korean Medicine (KM). The aim of this study was to investigate the difference of the tongue color assessed by computerized tongue image analysis system (CTIS) between the common cold (CC) patients and healthy subjects. A total of 85 participants, including 45 CC patients without organic diseases and 40 healthy subjects, were asked to complete the CC symptom questionnaire. A tongue image was acquired by using CTIS. Color differences in Commission Internationale de l'Eclairage (CIE) L*, a* and b* between the CC patient group and the control group were analyzes by using paired t-test analysis. The variable CIE b* of the tongue body was significantly lower in CC than that in controls (P=0.019). The variable CIE L* of the tongue coating was significantly higher in CC than that in controls (P=0.032). In CC, the color of the tongue body seems to be changed to intense red color. The color of the tongue coating seems to be changed to thick fur. The present study demonstrated that the CTIS can be used as a diagnostic and monitoring tool for the objective and standardized evaluation of common cold in clinics.

Objectives: The purpose of this study was to specify major tongue diagnostic indicators and evaluate their significance in discriminating pattern identification subtypes in stroke patients. Methods: This study used a community based multi-center observational design. Participants (n=1,502) were stroke patients admitted to 11 oriental medical university hospitals between December 2006 and February 2010. To determine which tongue indicator affected each pattern identification, a decision tree analysis of the chi-square automatic interaction detector (CHAID) algorithm was performed. The chi-squared test was used as the criterion in splitting data with a p-value less than 0.05 for division, which is the main procedure for developing a decision tree. The minimum sample size for each node was specified as n =10, and branching was limited to two levels. Results: From the 9 tongue diagnostic indicators, 6 major tongue indicators (red tongue, pale tongue, yellow fur, white fur, thick fur, and teeth-marked tongue) were identified through the decision tree analysis. Furthermore, each pattern identification was composed of specific combinations of the 6 major tongue indicators. Conclusions: This study suggests that the 6 tongue indicators identified through the decision tree analysis can be used to discriminate pattern identification subtypes in stroke patients. However, it is still necessary to re-evaluate other pattern identification indicators to further the objectivity and reliability of traditional Korean medicine.
