  • During the reign of King Sejong (世宗, 1418-1450) in the Joseon Dynasty, there were lots of astronomical instruments, including miniaturized ones. Those instruments utilized the technical know-how acquired through building contemporary astronomical instruments previously developed in the Song(宋), Jin(金), and Yuan(元) dynasties of China. In those days, many astronomical instruments had circles, rings, and spheres carved with a scale of 365.25, 100, and 24 parts, respectively, on their circumference. These were called the celestial-circumference degree, hundred-interval (Baekgak), and 24 direction, respectively. These scales are marked by the angular distance, not by the angle. Therefore, these circles, rings, and spheres had to be optimized in size to accomodate proper scales. Assuming that the scale system is composed of integer multiples of unit length, we studied the sizes of circles by referring to old articles and investigating existing artifacts. We discovered that the star chart of Cheonsang yeolcha bunyajido was drawn with a royal standard ruler (周尺) based on the unit length of 207 mm. Interestingly, its circumference was marked by the unit scale of 3 puns per 1 du (or degree) like Honsang (a celestial globe). We also found that Hyeonju ilgu (a equatorial sundial) has a Baekgak disk on a scale of 1 pun per 1 gak (that is an interval of time similar to a quarter). This study contributes to the analysis of specifications of numerous circular elements from old Korean astronomical instruments.

  • In the Buddhist paintings of the four devas, there is a change in the paper material of V aisravana(多聞天) in the early Joseon Dynasty. Until Goryeo Dynasty, Damuncheonwang, who holds a tower(塔) on the right side of Buddha was changed to the form which holds a mandolin(琵琶) in the early Joseon Dynasty. This change was first checked in Byeonsangdo in the Yuan period "The Avatamska Sutra(大方廣佛華嚴經, 1330~1336)", however the actual paper material change in the Buddhist painting is found first as a mural at the Tibetan temples, Cheolbangsa(哲蚌寺), Odunsa(吳屯寺), Baekgeosa(白居寺), which showed the change of tower which Vaisravaṇa held into mongoose. In Joseon Dynasty, also, new distribution of the four devas appeared first, which showed the change of paper material in the first floor roof-stones of Wongaksaji sipcheung seoktap, . However, the position of the four devas which held a tower and a mandolin consistently appear in the Buddhist paintings in the early Joseon Dynasty by mixing on the left and the right. This means the possibility that the paper material and the position of the four devas might be flexible in the early Joseon Dynasty. Just like reflecting this, painting image of the four devas in illustration of "saddharma-pundari-ka-$s{\bar{u}}tra$(Ming 1432, National Museum of Korea)" and illustration of "Jebulsejonyeorae-bosaljonjamyeongching-gagok(제불세존여래 보살존자명칭가곡, 1417)" has opposite position from each other. Therefore, the phenomenon in the Buddhist paintings of the early Joseon had a transitional characteristic which did not secure the fixed form of painting image by illustration of two copies where paper materials of the four devas were different, which characteristic can be said to be the characteristic of art in the transitional period.

  • Objectives : Radix Bupleuri is from the dried root of the herb of the Perennial herbaceous plant, Bulpleurum falcatum L. or Bulpleurum chinense DC. or Bulpleurum. scorzonerifolium Willd., family Umbelliferae. Medicinal Properties are bitter and pungent in flavor, slightly cold in nature and attributed to the liver and gallbladder meridians. Actions in modern Materia Medica are regulate the functional relation of internal organs to relieve fever, disperse the stagnated liver-qi and uplift yang-qi to raise sinking. The ‘uplift yang-qi to raise sinking’ efficacy, out of three efficacies (regulate the functional relation of internal organs to relieve fever, disperse the stagnated liver-qi and uplift yang-qi to raise sinking), has been disputed in the medical profession for a long period. Hereupon, this study ascertained the reason why it has been disputed. Methods : With respect to this medicinal herb, the efficacies of regulate the functional relation of internal organs to relieve fever, disperse the stagnated liver-qi and uplift yang-qi to raise sinking were described as to what was written in ‘Shen Nong's Herbal’ from Chin and Han dynasties until Jin and Yuan dynasties. Results : The beginning of Jin and Yuan dynasties, it began to deal with the ‘uplift yang-qi to raise sinking’ efficacy and so it has been carried on modern textbooks and medical books. The reason why it was added is that it was influenced by the theory of ‘Raise Sinking’ advocated by Zhang jieku who lived in the period of Jin and Yuan dynasties. Since then, the properties of ‘Radix Bupleuri’ have been wrongly known to the public. Additionally, ‘Radix Stellariae Seu Gypsophilae’, which was begun to be introduced from the Four Cities since the Five Dynasties, has been combined with the best stuffs of ‘Radix Bupleuri’ produced from Yin Zhou. Consequently, its original properties were remarkably disordered. Likewise, respective medical schools’ theories were changed by the influence of ‘Bulpleurum. scorzonerifolium Willd’ begun to be used since Tang dynasty. Conclusion : it is considered that the current ‘Raise Sinking’ efficacy of Radix Bupleuri is unreasonable to be applied to the efficacy of the whole Radix Bupleuri because it is limited to certain species.

  • Everyone once in a life experience headaches as symptoms are very common. According to a study in a country of more than a week and as many as those who have experienced a headache amounts to 69.4%. In addition, the high reported prevalence of migraine in 30s for 80% of all migraine sufferers daily life interfere with work or was affected. In Western medicine, the cause of headaches is traction or deformation of pain induced tissue like scalp, subcutaneous tissue, muscle, fascia, extracranial arteriovenous, nerves, periosteum. But it turns out there are not cause why pain induced tissue is being tracted or deformated. Therefore, most of the western-therapy is mainly conducted with regimen for a temporary symptom reduction. Therefore, I examined how it has been developed in Chinese Ming Dynasty, the perception of headache, change in disease stage and an etiological cause. Oriental medicine in the treatment of headache is a more fundamental way to have an excellent treatment. The recognition of head in "素問($s{\grave{u}}$ $w{\grave{e}}n$)" and "靈樞($l{\acute{i}}ng$ $sh{\bar{u}}$)" began to appear in 'Soul-神($sh{\acute{e}}n$) dwelling place' and 'where to gather all the Yang-'諸陽之會($zh{\bar{u}}$ $y{\acute{a}}ng$ $zh{\bar{i}}$ $hu{\grave{i}}$)'. Also, head was recognized as '六腑($li{\grave{u}}f{\check{u}}$) 淸陽之氣($q{\bar{i}}ng$ $y{\acute{a}}ng$ $zh{\bar{i}}$ $q{\grave{i}}$) and 五臟($w{\check{u}}$ $z{\grave{a}}ng$) 精血($j{\bar{i}}ng$ $xu{\grave{e}}$) gathering place'. More specific structures such as the brain is considered a sea of marrow(髓海-$su{\check{i}}$ $h{\check{a}}i$) in "內經($n{\grave{e}}i$ $j{\bar{i}}ng$)" and came to recognized place where a stroke occurs. Accompanying development of the recognition about head, there had been changed about the perception of headache and the recognition of the cause and mechanism of headache. And the recognition of headache began to be completed in Ming Dynasty through Jin, Yuan Dynasty. Chinese Ming Dynasty, specially 樓英($l{\acute{o}}u$ $y{\bar{i}}ng$), in "醫學綱目($y{\bar{i}}xu{\acute{e}}$ $g{\bar{a}}ngm{\grave{u}}$)", first enumerated prescription in detail by separating postpartum headache. and proposed treatment of headache especially due to postpartum sepsis(敗血-$b{\grave{a}}i$ $xu{\grave{e}}$). 許浚($x{\check{u}}$ $j{\grave{u}}n$) accepted a variety of views without impartial opinion in explaining one kind of headache in "東醫寶鑑($d{\bar{o}}ng-y{\bar{i}}$ $b{\check{a}}oji{\grave{a}}n)$" 張景岳($zh{\bar{a}}ng$ $j{\check{i}}ng$ $yu{\grave{e}}$), in "景岳全書($j{\check{i}}ng$ $yu{\grave{e}}$ $qu{\acute{a}}nsh{\bar{u}}$)", established his own unique classification system-新舊表裏($x{\bar{i}}nji{\grave{u}}$ $bi{\check{a}}ol{\check{i}}$)-, and offered a clear way even in treatment. Acupuncture treatment of headache in the choice of meridian has been developed as a single acupuncture point. Using the classification of headache to come for future generation as a way of locating acupoints were developed. Chinese Ming Dynasty, there are special treatments like 導引按蹻法($d{\check{a}}o$ y ${\check{i}}n$ ${\grave{a}}n$ $ji{\check{a}}o$ $f{\check{a}}$), 搐鼻法($ch{\grave{u}}$ $b{\acute{i}}$ $f{\check{a}})$, 吐法($t{\check{u}}$ $f{\check{a}}$), 外貼法($w{\grave{a}}i$ $ti{\bar{e}}$ $f{\check{a}}$), 熨法($y{\grave{u}}n$ $f{\check{a}}$), 點眼法($di{\check{a}}n$ $y{\check{a}}n$ $f{\check{a}}$), 熏蒸法($x{\bar{u}}nzh{\bar{e}}ng$ $f{\check{a}}$), 香氣療法($xi{\bar{a}}ngq{\grave{i}}$ $li{\acute{a}}of{\check{a}}$). Most of this therapy in the treatment of headache, it is not used here, but if you use a good fit for today's environment can make a difference.

  • ${\ulcorner}$Hwangje-Naegyeong (黃帝內經)${\lrcorner}$ is a source of all Korean traditional medical theories. Despite the importance of ${\ulcorner}$Hwangje-Naegyeong (黃帝內經)${\lrcorner}$, it is difficult to read and fully understand the contents because it is written in archaic language and many contents were missed now. Zhu dan Xi(朱丹溪, 1282-1358) is one of the most well-known four doctors in Jin-Yuan Dynasty(金元四大家). He insisted that ${\ulcorner}$Su-wen (素問)${\lrcorner}$ is the most important text book of traditional medical science, and established his medical theories based on it. This study has two objectives. One is to establish a base for comprehension and application of information contained in ${\ulcorner}$Su-wen (素問)${\lrcorner}$, and the other is to understand the medical theories developed by Zhu dan Xi(朱丹溪). Number of quotes related with ${\ulcorner}$Hwangje-Naegyeong (黃帝內經)${\lrcorner}$ in the eight books by Zhu dan Xi(朱丹溪) and his followers were extracted for my study.

  • Many of newly emerging diseases such as hypertension, stroke, diabetes, obesity, and atoptic dermatities are categorized into "Fire heat-disease(火熱病)" according to oriental medicine. It is because factors such as stress, overeating, and high fat diet are major causes of heat in the human body. Sun Yi-Kui(孫一奎), a well-known oriental medical doctor during Ming Dynasty's "Jia Jing Wan Li Nian Jian"(嘉靖萬歷年間 : A.D $1522^{\sim}1619$), established new theories on "Fire heat-disease-mechanism(火熱病機)". This study aims to investigate Dr. Sun's "Fire heat-disease-mechanism(火熱病機)"theory. For this purpose, I thoroughly examined the concepts of "Dong-Qj(動氣)", "Ming-Men(命門)", king fire(君火) and minister fire(相火) as well as pathological theory on "Fire heat(火熱)". In addition, I compared Sun's theory with those of Li Dong-yuan and Zhu dan-Xi.

  • Objectives As a method of body temperature distribution diagnosis, palpation of infants' forehead had been widely introduced in ancient East Asian medical classics. However, few attention have been paid to this diagnostic method - so called 'emaizhenduan (額脈診斷)'. So we studied the history of emaizhenduan and it's implication in modern clinical field. Materials and methods: To search the medical classic that contains any contents of emaizhenduan, we mainly used the electronic texts of Zhonghuayidian (中華醫典). To search modern study article on emaizhenduan, we used China National Knowledge Infrastructure (www.cnki.net), National Digital Science Library (ndsl.kr) etc. Results 20 kinds of East Asian medical classics were found to contain contents on emaizhenduan. The oldest one was Huoyoukouyi (活幼口議) which was written in Yuan dynasty of China. Only one modern TCM book was found to have comments on emaizhenduan, while some textbooks of pediatrics in Korean Medicine was found to have relatively sound introduction on emaizhenduan. Conclusion It is shown in ancient East Asian medical classics that infants' forehead temperature palpation was introduced as early as late 13th century in China, and have continuously been referred in many East Asian medical classics before modern era.

THE DEVELOPMENT OF THE SILK ROAD: THE POSTAL RELAY ROUTE OF MONGOL AND GORYEO

  • The Silk Road named by Ferdinand von Richthofen was not designated as a specific route. A lot of East-West trade routes had already existed across the continent and the geographical scope and definition of the Silk Road is still expanding. In particular, the claim that the Eastern end of the Silk Road reaches Gyeongju is an example of this expansion. Burial treasures from tombs on the Korean Peninsula have already been identified as products from the Sassanian Dynasty of Persia, and various archaeological and epical evidences support this finding. However, the specific route where these exchanges were made, around the 6th-8th centuries, has yet to be identified. Maritime as well as inland routes can easily be hypothesized. The Silk Road was largely activated by the Yam postal system with the expansion of the Mongol Empire. It not only served as an effective pathway for the Yuan to rule over the Goryeo, but also connected the Eastern end of the Silk Road to Gyeongju. This can explain the situation since the 13th century. Therefore, this paper claims that the Yeokcham system had been operating on the Korean Peninsula since the Unified Silla Kingdom, the previous period of Goryeo, or perhaps even before then. The Yeokcham should thus be regarded as a prototype of the Mongolian Yam, and the Korean peninsula should be recognized as another route which contributed specifically to the development of the Silk Road, not just as a user or a beneficiary.

  • Objectives : The publication year(1608) of Euilinchwalyo is very closed to the year(1610) of Dongeuibogam, so several researches indicate that Dongeuibogam was influenced by Euilimchwalyo. We, authors have recently focused on the way to quote books in Dongeuibogam and found particular aspects in the way of quotation between Euilimchwalyo and Dongeuibogam. Methods : 1. Comparing the contents of Sosokmyeongtang in quotation books between Euilimchwalyo and Dongeuibogam. 2. Tracing the origin of Sosokmyeongtang and comparing chief virtue, consist of herbal medicine, way of dose and making and the method of addition and subtraction in Sosokmyeongtang. Results : Beijiqianjiyaofang was the origin book that recorded Sosokmyeongtang but there was no methods of addition and subtraction. After Jin and Yuan dynasty, the books, which had Sosokmyeongtang, started to record the methods of addition and subtraction in Sosokmyeongtang. However, even though Euilinchwalyo also recorfed the methods of addition and subtraction in Sosokmyeongtang such as other medical books, Dongeuibogam didn't keep that way to document up. Conclusions : The fact that Dongeuibogam was influenced by Euilimchwalyo means 2 ways. The first is that Dongeuibogam was influenced by Euilimchwalyo directly. The second is that Heo Jun, who wrote Dongeuibogam, tried not to duplcate or follow Euilimchwalyo somehow.

  • From the reference research, the results obtained were as follows. 1. Until the "Song" dynasty, the predominant cause of facial nerve paralysis was the attack of Pathogenic Wind to "the Stomach Channel of Foot Yangming, (St.C.); and "the Small Intestine Channel of Hand Taiyang, (S.I.C.). They recognized the facial paralysis as an aspect of palsy. 2. In the period of Jin-Yuan(金元), the predominant cause was described as "Xuexu"(the deficiency of blood) and phlegm. They recognized that the facial palsy was a palsy. However, they also acceded to the possibility that there could be other explanations. 3. In the period of "Ming & Qing", there were numerous kinds of causes. For example, the following were identified as attacking the Meridian: the Pathogenic Cold; Pathogenic Heat; "Xinxu"(the deficiency in the heart); Fire and Heat combined as a pathogenic factor; "Pixu"(the deficiency in the spleen); and, "Xinxu"(the deficiency of blood). 4. In the past, Koreans have explained the facial paralysis according to the Chinese theories mentioned. However, recently there has been an emergence of another Chinese theory; whereby, facial paralysis is classified into causes and symptoms, and then medical treatment is applied accordingly. 5. From the occident medical perspective, the facial paralysis is categorized into two causes. The first is called central facial nerve paralysis and the second is called peripheral facial nerve paralysis. The latter is mainly caused by Bell's palsy, Herpez zoster oticus, and trauma.
