Objectives : We propose a method to disassemble Traditional East Asian Medicine herbal formulas using machine learning. Methods : After creating a model using Byte Pair Encoding(BPE) and G-Score, the model was trained with training data. Afterwards, the learned model was applied to the test data, of which the results were compared with expert opinion. Results : The results acquired through the model were not significantly different from those of modern expert opinions. However, there were cases where the meaning was partially unclear, while there were cases where new knowledge could be obtained through the disassembling process. Conclusions : It is expected that disassembling herbal formulas through the proposed method in this study will help save resources required to understand complex ones.

Objectives : This article examines the validity of the argument by Dorfer et al. that the tattoos of the 5200-year-old mummy, found in Tyrolean Alps in 1991, are the oldest remains of acupoints or meridians. Methods : Firstly, I reviewed the arguments by Dorfer et al. and the rebuttal by Ma et al. Secondly, I investigated whether the tattoo locations were in accordance with the acupoint locations and meridians documented in Chinese medical classics. Finally, I examined the alternative explanations on the reasoning of their locations by Kean et al. Results : Among the 18 groups of tattoos in total, only 3 groups coincided with classical acupoints, which accounts for 16.7% of total groups. Although 4 groups may also have been acupoints locations, this hypothesis could not be confirmed through an accurate standard of measurement. Conclusions : It is highly possible that the tattoos of the Tyrolean mummy do not have any relationship with classical acupoints and meridians. The tattoos are not decorative, but meant for medicinal purposes. They correspond to chronic musculoskeletal trauma and pain sites.

Objectives : We would like to study what is the most appropriate "feature" to effectively perform authorship attribution of the text of Traditional East Asian Medicine Methods : The authorship attribution performance of the Support Vector Machine (SVM) was compared by cross validation, depending on whether the function words or content words, single word or collocations, and IDF weights were applied or not, using 'Variorum of the Nanjing' as an experimental Corpus. Results : When using the combination of 'function words/uni-bigram/TF', the performance was best with accuracy of 0.732, and the combination of 'content words/unigram/TFIDF' showed the lowest accuracy of 0.351. Conclusions : This shows the following facts from the authorship attribution of the text of East Asian traditional medicine. First, function words play an important role in comparison to content words. Second, collocations was relatively important in content words, but single words have more important meanings in function words. Third, unlike general text analysis, IDF weighting resulted in worse performance.

Objectives : This study examines the grounds on which Wulao(五勞) Liuji(六極) Qishang(七傷) which are categories of Xulao(虛勞) are differentiated, along with standards by which each category is further classified. Methods : Based on "Zhubingyuanhoulun(諸病源候論)", the first text to sort the different types and symptoms of Wulao(五勞) Liuji(六極) Qishang(七傷), each classification and its symptoms were analyzed. Texts which were written relatively close in time to "Zhubingyuanhoulun" were referenced in the process. Results & Conclusions : The differentiation of Wulao(五勞) Liuji(六極) Qishang(七傷) is based on the cause of illness. Wulao(五勞) is caused by mental activity which fatigues the Five Zang, Liuji(六極) is caused by exterior pathogens that damage the Five Body Elements, and Qishang(七傷) is caused by emotional factors as well as damaging practices. In close examination, Wulao(五勞) was further classified according to the different layers of mental activity, described in terms of taxation illness of the damaged Zang. Liuji(六極) is damage of the Five Body Elements by exterior pathogens, which was put into the spacial structure of nature and explained in six. Qishang(七傷) refers to the collective of representative symptoms and representative causes of Xulao.

Objectives : Chimgugyeongheombang's Byulhyul, or special points, is a list of extra points, and its acupoint types and positions are different from other books. Its source, however, is kept behind the vale. This paper aims to reveal Byulhyul's contents and source. Methods : Qixiaoliangfang, Jinjiudacheng, and Donguibogam's Gihyul were studied to determine the source of Chimgugyeongheombang's Byulhyul. Results & Conclusions : Chimgugyeongheombang lists a total of 59 special points. It cites 22 meridian points from Qixiaoliangfang, 26 points from Jinjiudacheng, and 36 points from Donguibogam. The Dictionary of Acupuncture records the source of 6 meridian points that aren't found in conventional books, namely the Soongol, Backro, Yeose, Eumdo, Naetaechoong, and Gabgeun points, as Zhenjiujicheng. However, Zhenjiujicheng, in reality, is a book put together with excerpts from three books: Donguibogam, Chimgugyeongheombang, and Leijingtuyi. This means that it's Chimgugyeongheombang that is the source of Zhenjiujicheng. Moreover, all of the points save for Soongol and Eumdo were also used in the acupunctural treatment of 9 diseases including epilepsy. In other words, it can be safely assumed that Heo Im came up with and utilized new special points based on his personal clinical experiences, and this is significant in that he expanded the boundary of the conventional study of acupuncture through his independent experiences and studies.

Objectives : The purpose of this paper was to examine quantitative methods for estimating and detecting local text reuse in the texts of East Asian Traditional Medicine. Methods : We introduce techniques that estimate the volume of local text reuse with n-gram and those that directly detect the reuse with the Smith-Waterman algorithm (SW algorithm). Based on this, the estimation and detection of local text reuse were carried out for 『Donguibogam』 and 『Huangdineijing·Suwen』. Results : Estimates with n-gram had more errors than methods with SW algorithms. SW algorithms detected suspected strings directly with local text reuse, resulting in more accurate results. Conclusions : Although n-gram does not accurately find local text reuse, its high speed makes it a preferable method for certain purposes, such as screening similar documents. On the other hand, SW algorithms have the advantage of being relatively good at finding similar phrases suspected as local text reuse even if the strings do not completely match. However, due to its excessive consumption of time and computing resources, its benefits are limited to cases where precise results are required.

Objectives : To investigate how 『Duchanggyeongheombang』 has been adopted and edited in practical texts such as 『Gosachwalyo』, 『Sallimgyeongje』, 『Gosasinseo』. Methods : Based on the disassembled verses of a paragraph in the 『Duchanggyeongheombang』, the 「Duchanggyeongheombang」 contents in 『Gosachwalyo』, 『Sallimgyeongje』,『Gosasinseo』 were compared and examined. Results : 『Gosachwalyo』 directly summarized and quoted the contents of 『Duchanggyeongheombang』 written by Park, Jinhee, while the contents in 『Sallimgyeongje』 and 『Gosasinseo』 are mostly similar, summarizing and quoting from 『Gosachwalyo』. Conclusions : In the perspective of text categorization, while the professional and specialized contents of 『Duchanggyeongheombang』 has been excluded, it was edited in ways of increasing practicality. As these texts were widely dispersed to the public, we can conclude that 『Duchanggyeongheombang』 was very influential in the treatment of douchang(痘瘡, smallpox) among the public.

Objectives : This study was conducted to infer the effect of superficies-resolveing herbs by analyzing effect terms which have extracted and refined, based on four temperatures and five tastes. Methods : Firstly, temperatures, tastes and effect terms were extracted from the 27 kinds of superficies-resolving herbs written in Herbology. Then, each effect terms was divided into single meaning term and refined as typical term, using the inclusive effect terms I established. After that, herbs were grouped by tastes and found the effect terms which are mentioned most frequently. Results & Conclusions : All the superficies-resolving herbs can have wind-dispelling effect and superficies-resolving effect, except Bulpleuri Radix. This herb is able to has just the wind-dispelling effect. And it's more appropriate to categorize Bulpleuri Radix to heat-clearing herb group than superficies-resolving herb group, considering its several, distinctly cold characteristics. Some effects are concentrated to wind-cold-dispersing herb group and others to wind-heat-dispersing herb group. Each tastes has its own representative effect group.

Objectives : This study examined the characteristics of famine relief and fasting formulas in Korean Medical Texts from early Joseon to early modern period. Methods : In addition to previous studies and texts, basic materials were collected from various academic database such as the Korean Medical Classics Database, Korean History Database, Chinese Text Project, Weijiwenku, etc., then analyzed. Results : In Korean Medicine from the early Joseon to early modern Korea, there was a strong awareness to use fasting prescriptions which were applied in Daosim for the purpose of famine relief, using both medicinals and common food ingredients together as complex prescriptions rather than single ingredient formulas. Famine relief and fasting formulas were continuously listed in many medical texts published after the Donguibogam, in modified or newly improved forms. Moreover, the food ingredients and medicinals used in these formulas were consisted of those which could be easily found in the famished nation of the time. Many of these formulas were tried and tested prescriptions, frequently used in clinical settings. Most of the ingredients and medicinals used in the famine relief and fasting formulas were sweet, bland, and neutral in nature, supporting Qi circulation and tonifying the Spleen and Stomach. Therefore in times of famine, these medicinals could help prevent digestive problems and decline of stamina. Conclusions : Research and contemporary interpretation on the famine relief and fasting formulas could contribute to not only health management but to relieving nutrition imbalance and famine, expanding the field of Korean Medicine application.

Objectives : Medical records of Xueji in the "Xiaozhufurenliangfang" were examined in this study which aimed to look at the medical situation in gynecology of China's Ming Dynasty period, in hopes for it to yield implications and treatment directions to gynecology in $21^{st}$ century Korea. Methods : The medical records were systematically organized with a medical anthropological approach along with overall analysis of the entire records, which lent meaningful statistical information in numeric form. A bibliographical review of the text as historical artifact was undertaken as well. Results : In managing gynecological conditions, Xueji frequently attributed them to depletion of Qi and Blood of the Spleen and Liver. In terms of pathogenic factors, he frequently mentioned Fire and Heat, and as etiological factors, emotional distress. For treatment, he frequently used 'Bu Zhong Yi Qi Tang(補中益氣湯)', 'Xiao Yao San(逍遙散)' and 'Gui Pi Tang(歸脾湯)'. Conclusions : Through studying the medical records of Xueji in "Xiaozhufurenliangfang" a close look into a master's insight on gynecological disorders in terms of diagnosis and treatment was achieved. The formulas he used are widely applied even today, and this study shows that the formulas's clinical application could be expanded even wider.
