Indigo [鴉靑] was used as a symbolic color in 15^th century diplomacy. This study reinforces the historical research for characteristic and shapes of indigo colored royal clothing gift in King Seongjong's reign with a focus on po [袍] and ieom [耳掩]. Clothing made of fur that was combined with satin damask, silk gossamer [綃] were frequent gift, and a sable coat was a symbol of high-ranking clothes. Another clothing's materials were satin damask, sheer fabric gauze [羅], cotton, tabby with silk and ramie [紵絲]. The indigo color of King Seongjong's reign was recommended not for luxury. Historical research factors for indigo clothing gift were extracted from noblemen's relics. Danryeong and jigryeong are shaped of narrow sleeves and trapezoid gusset pleated in and out. Sable coat can consist of satin damask outshell, sable lining, and double oblique collar. Heohyung are presumed types of short sleeved fur vests. Ieom can be reconstructed with an indigo fabric outshell and sufficient fur. Dapho has gusset pleated wide and narrow. As additional gifts, the shapes of yoseon-cheopri and cheopri were analyzed. We selected a commercial fabric similar to relics and an indigo powder dyeing method to remedy a lack of traditional material. The reconstructed data were presented as flat drawings and samples.

The purpose of this study was to consider the kinds and features of costume and fabrics of the early Koryo period which are mentioned in the records of costume system, royal presents and diplomatic articles at that time ranging from the reigns of king Gwangjong to king Gyeongjong and to king Seongjong. Findings of the study can be summarized as follows. In the 11th year of king Gwangjong's reign, the official costume system was established, which reflected the royal will to independence as an imperial nation. That system also became the basis of the official wage system in king Gyeongjong's reign. In the reigns of king Gwangjong and king Gyeongjong, the monarch granted official uniforms to persons who passed the state examination, directly connecting with new bureaucrats and strengthening the royal authority. Those uniforms were usually worn at a banquet where the monarch and subjects participate together in the early Koryo period. In the reign of king Seongjong, costume and fabrics were positive means of realizing political Confucianism as they were used for bureaucrats who advanced to official position through the state examination. Records issued at that time explain that the monarch presented costume and fabrics in an effort to getting along with officials and civilians of different classes as the state and the royal authority stabilized. Found in the records released in the reigns of king Gwangjong to king Seongjong, the kinds of costume or fabrics at that time include jikseongeuio, gap, yongeui, seupeui, gyegeum baekcheop, geumeunseon gyegeumpoyok and po. The techniques of manufacturing armors in the early Koryo period were probably advanced since the item was a craftwork presented to the court in the reigns of kings Gwangjong and Gyeongjong. Presumedly, baekcheop was a kind of hemp and po. Koryo's native hemp cloth.

This study examines the transitional situation that can be seen from the palace operation in early Joseon Dynasty. The first decades of Joseon after the nation was founded differ from the Joseon Dynasty as a whole, but rather similar with the Goryeo Dynasty. By examining "The History of Goryeo(高麗史)," it showed that palace operation during the Goryeo Dynasy was marked by the fact that a separate palace was built and resided in despite the existence of the Bongweol(本闕, main palace) as the central palace. The separation of the parent's generation and the children's generation was shown through the establishment of one's own palace. Such trait of Goryeo affected palace construction directly after the founding of Joseon. This can be shown from the characteristic of palace operation by generation. The construction of the Changdeokgung Palace(昌德宮) of King Taejong, as his own palace, is an example. Afterwards, the palace system of Joseon was established, and the space of the king and the crown prince was merged through ritual reform during the reign of King Sejong. However, the space for the parents of the king were considered separate, and this influence continued to the reign of King Seongjong. The construction of Changgyeonggung Palace(昌慶宮) during the reign of King Seongjong is an event where the king proclaimed the separation with his mother and grandmother.

The purpose of this study is to analyze how medical texts in Joseon Dynasty have changed in time and to understand their characteristics. Medical texts that reflect the medical standards of the time were enable us to look into how medical bureaucrats were trained and education policies related to the training. Chinese medicine influenced Joseon Dynasty's medicine in different ways at different times. Before the Imjin War, Joseon dynasty's medicine was largely under the influence of the Song dynasty's medicine. After the war, the four noted physicians of Jin-Yuan era had increasingly more significant influence, along with the introduction of Ming dynasty's medicine. The facts found through this study include : 1) the basic courses were composed of Chandomac (纂圖脈), Dongingyeong (銅人經), and Boncho (本草); 2) Josenization of medical division system was established for the first time during the reign of King Sejo (世祖), and updated throughout the time of the King Seongjong (成宗) and King Sun Jo (宣祖); 3) Hyangyak (鄕藥) education with medical texts was limited to some periods like King Seongjong (成宗) and King Sejo (世祖); 4) the high proportion of Bangseo (方書) in the early era gradually decreased, and more of specialized and comprehensive medical books came to find their way into the standard curriculum.

We analyze the design and specifications of the Sun-and-Stars Time-Determining group of instruments (Ilseong-jeongsi-ui, 日星定時儀) made during the Joseon dynasty. According to the records of the Sejong Sillok (Veritable Records of King Sejong), Sun-and-Stars Time-Determining Instruments measure the solar time of day and the sidereal time of night through three rings and an alidade. One such instrument, the Simplified Time-Determining Instrument (So-jeongsi-ui, 小定時儀), is made without the essential component for alignment with the celestial north pole. Among this group of instruments, only two bronze Hundred-Interval-Ring Sundials (Baekgak-hwan-Ilgu, 百刻環日晷) currently exist. A comparison of the functions of these two relics with two Time-Determining Instruments suggests that the Hundred-Interval-Ring Sundial is a Simplified Sundial (So-ilyeong, 小日影), as recorded in the Sejong Sillok and the Seongjong Sillok (Veritable Records of King Seongjong). Furthermore, the Simplified Sundial is a model derived from the Simplified Time-Determining Instrument. During the King Sejong reign, the Sun-and-Stars Time-Determining Instruments were used in military camps of the kingdom's frontiers, in royal ancestral rituals, and in royal astronomical observatories.

The "Annals of the Joseon Dynasty (朝鮮王朝實錄)" is the precious historical material which contains royal culture of Joseon dynasty as an official document. It kept a record of the diseases and treatments relating to the 27 Kings for a period of 518 years, who had a variety of different symptoms. Among them the most frequent disease was a skin disorder such as a boil of a painful infected swelling. Dermatosis became the direct cause of death of several Kings. In this article we tried to conduct research using the "Annals of the Joseon Dynasty" into the skin diseases of the Kings during the first period of Joseon dynasty from the first King Taejo (太祖) to the 12th King Injong (仁宗). Among the 12 Kings, the 5th King Munjong (文宗), the 7th King Sejo (世祖), the 9th King Seongjong(成宗), the 10th King Yeonsangun (燕山君), and the 11th King Jungjong suffered from dermatosis. The King Munjong died at the age of 38 and suffered from severe boils before his death. The cause of death is thought to be septicaemia. The King Sejo does not have any specific record of skin disease, however, the recently discovered relics showed the indications of serious skin trouble of boils. The King Seongjong suffered from skin diseases at the age of 20, 27, 28 and 38. Nevertheless, the direct cause of death was not dermatosis. The King Yeonsangun had skin trouble of boils on his face when he was 20. He lost the throne and died of an infectious disease at 31. The King Jungjong had a record of suffering from dermatosis at the beginning of twenties, at the middle of forties, and at the age of 57 when he died. The skin trouble affected the whole of the body. He was treated with acupuncture therapy and medication for both internal and external uses among which folk remedies were included.

${\ulcorner}$Classified Collection of Medical Prescriptions${\lrcorner}$(1445) is a book compiled the medical achievements of China and Choseon in those times and it's our source of pride to have it In this country. It also deserves careful investigation since this book can provide some clues of features of missing books in China and Korea. The extent of accuracy of xylographica of old books determines the possiblity of in depth further study. So authors attempted to investigate the xylographica of ${\ulcorner}$Classified Collection of Medical Prescriptions${\lrcorner}$ one of the 3 main books in Korea. Previous investigation done by Miki Sakae and Kim Doo Jong are noticeable. On the basis of their respective works, we analyzed 'Annals of the Choseon Dynasty' to find records related with ${\ulcorner}$Classified Collection of Medical Prescriptions${\lrcorner}$ and estimated the situation of its publication. We tried figure the situation of those times of China, Japan and Korea(including North Korea) and tried to estimate the book's original xylographica as much as we could. By King Sejong's command, the first draft of ${\ulcorner}$Classified Collection of Medical Prescriptions${\lrcorner}$ consisted of 365 books was made by collaboration of civil officials and medical officers during the period from 1443 to 1445. And then from 1451(first year of Moonjong's reign) to 1464(l0th year of Sejo's reign) lots of manpowers were employed and through the process of countless erasure, proofreading, arrangement and rearrangement revised version of ${\ulcorner}$Classified Collection of Medical Prescriptions${\lrcorner}$ which is called by Sejo text was completed. After 3 years of wood engraving work, the first printed form of ${\ulcorner}$Classified Collection of Medical Prescriptions${\lrcorner}$ (alternately called Seongjong text) in folding case consisted of 266 chapters, 264 volumes came into the world in 1477.(8th year of Seongjong's reign). This was 32 years after the initial completion of the edition. So ${\ulcorner}$Classified Collection of Medical Prescriptions${\lrcorner}$ exists in three forms as Sejong text, Sejo text and Seongjong text respectively. Since those texts were plundered during the Japanese invasion of Korea in 1592, none of the original copy remains within korea. The texts were constantly moved to kadeungcheongieong, to Kongdeungpyeongio, Jesookoan of Edo, to East University of department of classic books, to Cheoncho archives, to the Imperial Museum and finally is kept in the royal palace at present. (Doseoryo text Eulhae printing type) Reduced-size republication books of ${\ulcorner}$Classified Collection of Medical Prescriptions${\lrcorner}$ in wooden type were imported at the time of 'Byeongja Korea-Japan Treaty in 1876' and of those 2 books, one copy was treasured in the Royal Household of the Yi Dynasty and than was lost during the Korean War circa 1950. The other remaining copy has been kept succesively by Kojong's imperial grant, Royal doctor Hong Cheol Bo, Hong Taek Joo, Hong Ik Pyo the book agent, and now is kept In Yonsei University Library and this is the only existing copy in Korea at present. In 1965, Dongyang Medical college published the transcription version of ${\ulcorner}$Classified Collection of Medical Prescriptions${\lrcorner}$ consisting of 11 books and then in 1981 after edition and arrangement by Choonghoa(中華) publishing company, photoprint copy of ${\ulcorner}$Classified Collection of Medical Prescriptions${\lrcorner}$ was published in Keumgang(金剛) publishing company In 1991, October Yeokang(驛江) publishing company producd photocopies of ${\ulcorner}$Classified Collection of Medical Prescriptions${\lrcorner}$ which were previously translated into Korean by North Korea Institute of Oriental Medicine and then issued by medical publishing company. In China, two institutes, Zhejiang Institute of Traditional Chinese Medicine and Huzhou Traditional Chinese Medical Hospital cooperated to publish a revised and marked text consiting of 11 books by adding marking points to japanse Edohakhoondang text which were used as a reference. Both the korean and chinese texts issued were grounded by the ${\ulcorner}$Classified Collection of Medical Prescriptions${\lrcorner}$ kept in the royal palace. Any further study concerning ${\ulcorner}$Classified Collection of Medical Prescriptions${\lrcorner}$ can acquire its accuracy and objectivity when the japanese text kept in the royal palace is taken as an original copy.

A numerical model based on the mode superposition method is used to study the vortex-induced vibration response characteristics of a deep-sea riser such as steel catenary riser (SCR). A steel catenary riser can be modeled using a flexible cable with simple supports at both ends. The natural frequency, mode shape and mode curvature of the riser are calculated and the vortex-induced vibration response of the riser is obtained using the equilibrium of the input and output power. The mode superposition method is applied to the vibrational stresses for each mode to calculate the overall riser fatigue life.
