  • Objectives: The purpose of this study is to develop a standard tool for pattern identifications in Korean Medicine for depression. Methods: The advisor committee for this study was organized by 15 Korean Medicine neuropsychiatry professors from 11 Colleges of Korean Medicine. The items and structure of the tools were based on reviews of published literature. In order to develop the tool, we took the consultation from discussions with the advisor committee twice and also incorporated additional advices from e-mail correspondences. Results: 1) We divided the symptoms and signs of depression into 11 pattern identifications. 2) We obtained the mean weights which reflected the standard deviations from each symptoms of the 11 pattern identifications which were scored on a 100-point scale by 15 experts. 3) We designed the Korean medicine pattern identification tool for depression. It was composed of 66 questions in the question- and-answer format. Conclusions: There are some points which should be considered in this study. First, we couldn't reach a complete agreement on the concept of 11 patterns. Second, each pattern identification has a different number of symptoms and signs. In addition, the items of symptoms and signs of each pattern identification are unequal. Third, as we did not set any clinical trials when using this tool, it was not possible to test its validity and reliability. Although there are some limits in this study, the development of pattern identification tools for depression through discussions with the advisor committee is meaningful. If the validity and reliability of the Korean Medicine pattern identification tools for depression are confirmed through clinical trial,s this tool is expected to be applied to the subsequent researches in the future.

  • Objectives : By analyzing symptoms of tinnitus, we tried to find out the relationship between deficiency and excess(虛實) and visceral pattern identification(臟腑辨證). By testing Tinnitus Handicap Inventory(THI), we evaluated the quality of life of people suffering from various aspects of tinnitus, as well as comparing treatment efficiency. Methods : 52 patients were recruited in this study who was ill with tinnitus. They wrote out the questionnaire about tinnitus and the THI. Results : The vast majority of high-grade tiny noise patients are deficiency type(虛症). The vast majority of low-grade roar patients are excess type(實症). Tinnitus persistence and feeling of ear occlusion were prominent in low-grade roar patients. low-grade roar patients suggest that overall quality of life is lower than high-grade tiny noise patients. In terms of treatment efficiency, spleen-stomach weakness(脾胃虛弱)-type, stomach heat(胃熱)-type and phlegm-fire(痰火)-type was higher than kidney essence depletion(腎精虧損)-type and liver qi depression(肝氣鬱結)-type regardless of the aspect of tinnitus. Conclusions : The present study suggests that tinnitus pattern may be helpful in differentiating patients with tinnitus, and the effectiveness of treatment can be predicted through differentiation.

  • Purpose: The standard tool for the pattern identification is used for identifying patterns in patients using a questionnaire. The purpose of this study is to reorganize the standard tool for the pattern identification of gastroesophageal reflux disease (GERD) developed in 2017 and to analyze the reliability and validity of the standard tool for pattern identification by applying it to GERD patients. Methods: To reorganize the standard tool for the pattern identification of GERD developed in the previous study, we searched the literature in the main databases, OASIS (Oriental Medicine Advanced Searching Integrated System) and CNKI (China National Knowledge Infrastructure). We added the search results to the data used in the previous study and went through the reorganizing courses, such as evaluating the validity of the translation, the Delphi technique, and a small survey. After reorganization, the patients who visited the Kyunghee University Korean Medicine Center for GERD symptoms were provided the questionnaire, including the reorganized standard tool for pattern identification. We analyzed the survey results to evaluate their reliability and validity. Results: Fifty patients completed the questionnaire. Reliability analysis results showed a pattern identification match rate of 86%, Cronbach's α coefficient of 0.834, and intraclass correlation coefficient of 0.907. The Mann - Whitney U test and logistic regression were implemented to check the relations between the survey questions and pattern identification results; the Pearson correlation, compared with other scales, showed a moderate score. Conclusion: We reorganized the standard tool for the pattern identification of GERD to be updated on current issues and so that it is easily used. The analysis results of the questionnaire showed that the reorganized standard tool had high reliability and moderate validity.

  • Objectives : This study was aim to investigate the relationship between NIHSS and distribution of pattern identification in stroke patients. Methods : 1471 participants from the patients hospitalized for stroke within 4 weeks from April 2007 to August 2009 were included. They were grouped according to the NIHSS score; group 1 for the participants whose NIHSS were less than six, group 2 for seven to fifteen, and group 3 for over than sixteen. And the patients were re-divided into two groups according to their post-onset interval. The difference of distribution of five pattern identification for each group were investigated. And five pattern identification were re-analyzed according to the deficiency-excess pattern identification. K-W test was used for statistical synthesis, and the result was regarded as significant one, if its p-value was below 0.05. Results : Dampness-phelegm pattern was the most frequent out of five patterns in total participants as well as all the subgroups. In group 3 with more serious neurological deficit, larger proportion of patients in early acute stage was diagnosed as excess pattern including Fire-Heat pattern. On the other side the proportion of Deficiency of Qi and Yin was larger in late convalescent stage of group 3 than in other groups. But nothing was statistically significant. Conclusions : Further study including patients with more variant classification with follow-up evaluation is needed to reflect the real characteristics of stroke population.

  • With the advent of the Information Age, the source identification of digital images, as a part of digital image forensics, has attracted increasing attention. Therefore, an effective technique to identify the source of digital images is urgently needed at this stage. In this paper, first, we study and implement some previous work on image source identification based on sensor pattern noise, such as the Lukas method, principal component analysis method and the random subspace method. Second, to extract a purer sensor pattern noise, we propose a sample selection method to improve the random subspace method. By analyzing the image texture feature, we select a patch with less complexity to extract more reliable sensor pattern noise, which improves the accuracy of identification. Finally, experiment results reveal that the proposed sample selection method can extract a purer sensor pattern noise, which further improves the accuracy of image source identification. At the same time, this approach is less complicated than the deep learning models and is close to the most advanced performance.

  • This study was aimed to develop the instrument of Korean medical pattern Identification and Functional Evaluation for Five Organ. This study followed seven steps, consisted of first composition of research members, second set-up of the aim, third review for advanced research, fourth finding an important index, fifth puting on the weight for index, sixth advice from linguist and last development of draft of questionnaire. Twenty two in and out researchers joined and put the weight on each question. We developed a draft version of questionnaire of Korean medical pattern identification and functional evaluation for five organ. Most questions between pattern identification and functional evaluation of five organ have similar weight, but several ones have difference in order. Generally, specific symptom represented specific location or related with pain have relatively higher weight on pattern identification, and weakness question gained weight on functional evaluation. We develop the questionnaire of Korean medical pattern identification and functional evaluation for five organ. Following study, which will evaluate the reliability and validity, is needed.

  • Objectives : Our purpose of this study was to evaluate the association between abdominal adipose tissue and oriental obesity pattern identification. Methods : This study was performed in 78 healthy obese(BMI(body mass index)${\geq}25kg/m^2$) women in Seoul. Subjects underwent abdominal CT(computed tomography) scanning and were asked to complete the oriental obesity pattern identification questionnaire. Subjects were given written consent and this study was performed under permission of institutional review board of Kyung-hee East-west Neo medical center. Results : 1. VFA(visceral fat area) and VSR(visceral/subcutaneous adipose tissue ratio) were significantly correlated with stagnation of the liver qi(肝鬱, gan-yu)(p<0.05). But, other patterns were not significantly correlated with oriental obesity pattern identification(p>0.05). 2. We evaluated a difference of oriental obesity pattern identification score in visceral obesity group(n=34) versus non-visceral obesity group(n=44). Scores of all patterns except food accumulation(食積, shi-ji) were significantly higher in the visceral obesity group than in the non-visceral obesity group(p<0.05). Especially, there was a further significant difference in stagnation of the liver qi(肝鬱, gan-yu)(p<0.01). Conclusions : Generally, the stagnation of the liver qi(肝鬱, gan-yu) has a close relation with stress and depression. This study suggests that stress and depression might be correlated with visceral fat, and the use of oriental obesity pattern identification would be helpful for planning a treatment schedule of visceral obesity in the clinic.

  • 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.

  • Objectives We aimed to analyze traditional Chinese medicine (TCM) literatures in regards to the pattern identification and related symptoms of idiopathic short stature (ISS). Methods We searched relevant literatures published up to September 29, 2020 through three Chinese electronic databases. We performed frequency analysis of the selected studies by extracting information on pattern identification, clinical symptoms, and TCM treatments presenting pattern identification of ISS. Results Sixteen studies were included. Spleen deficiency, kidney deficiency, dual deficiency of spleen-kidney, and liver-kidney yin deficiency were frequently reported. Clinical symptoms of the spleen deficiency include sallow complexion, body constituent weakness, anorexia, lack of qi and no desire to speak, and loose stools. Herbal medicines (HMs) such as Sijunzi-tang were frequently reported. Clinical symptoms of the kidney deficiency include cold limb and fear of cold, soreness and weakness of waist and knees, and clear and long urine. HMs such as Bishendihuang-wan were frequently reported. Clinical symptoms of the dual deficiency of spleen-kidney include body constituent weakness, spirit lassitude and lack of strength, anorexia, soreness and weakness of waist and knees, and cold limb and fear of cold. HMs such as Sijunzi-tang plus Bishendihuang-wan were frequently reported. Clinical symptoms of the liver-kidney yin deficiency include tidal fever and night sweating, heat in the palms and soles, dizziness, and dry throat. HMs such as Liuweidihuang-wan were frequently reported. Conclusions This was the first study to analyze the frequency of pattern identification and related symptoms on ISS. In the future, a standardized Korean medicine pattern identification system should be established.
