Objectives : To examine the progression and presentation of King Jeongjo's Gyeok-ki(膈氣) symptoms during his reign. Methods : Based on recordings in the The Daily Records of Royal Secretariat of Joseon Dynasty related to Gyeok-ki(膈氣), characteristics of King Jeongjo's case was analyzed, then compared and examined against the political situation he was in. Results : During the 24 years of reign, King Jeongjo's Gyeok-ki(膈氣) developed in four stages; beginning stage with mild symptoms, intrinsic stage where it became the King's main disease, peak stage where symptoms intensified, and chronic stage where symptoms became rather manageable but the disease occurred regularly. Conclusions : From the year of accession to the year of death, King Jeongjo consistently complained of Gyeok-ki(膈氣), which seems to be strongly related to his family history and political situation.

Queen Myeongseong was the wife of King Hyeonjong, the 18th king of the Joseon Dynasty, and the mother of King Sukjong. The clinical records of Queen Myeongseong are summarized on the basis of the Seungjeongwon Ilgi (The Daily Records of Royal Secretariat of Joseon Dynasty 承政院日記) and reviewed through Donguibogam. Queen Myeongseong gave birth to one male and three female children in the time of the queen. She took Geumgaedangguihwan (金櫃當歸丸), Dalsaengsan (達生散), Antaeum (安胎飮) during her pregnancy and Gungguitang (芎歸湯) during postnatal care. Since 1669, chest tightness, sleeplessness, arm pain and numbness of arms had been appeared. Ondamtang (溫膽湯) and Dodamtang (導痰湯) were used but they were not effective. However, when her symptoms were regarded as a benign tumor due to cold and wetness, there was a difference in the use of Ohjuksan (五積散). In 1683, when king Sukjong was caught in a smallpox, she took care of him. She exorcised in the middle of winter to pray for her son's recovery, and died of the flu.

The origin of the Korean Screen Planisphere with both Traditional and New Star-Charts, made by Korean Astronomers in the Royal Astronomical Bureau of the Joseon Dynasty by adopting the knowledge of the European astronomy, is investigated by analyzing its inscriptions and star charts. The considerations on both the changes in notations or representations of names of asterisms and the naming taboos used in the Old-style planisphere imply that the star-chart is originated from either the Sukjong-Stele-Replica of Cheonsang-Yeolcha-Punyajido(天象列次分野之圖). The New style planisphere is just the reproduction of Huangdao-congxingtu (黃道總星圖), with the exception of the non-Chinese-traditional stars. The Huangdao-congxingtu was made in 1723 CE by Ignatius K$\ddot{o}$gler who was a Jesuit missionary and worked for the Bureau of Astronomy (欽天監) in the Qing Dyansty. I find that the star chart was imported in 1742 CE from the Qing by An Gukrin (安國麟) who was an astronomer in the Royal Astronomical Bureau of Joseon. The chart became model for the screen star-chart made in 1743 CE and now housed in Bopju temple. I found that the inscriptions are extracted from the sentences in both Xinzhi Lingtai Yixiangzhi (新製靈臺儀象志) and Qinding Yixiangkaocheng (欽定儀象考成). Korean historical records in either Daily Records of the Royal Secretariat of the Joseon Dynasty (承政院日記) or Annals of the Joseonn Dynasty (朝鮮王朝實錄) show that Xinzhi Lingtai-Yixiangzhi was imported from the Qing Dynasty in 1708 CE, and the Qinding Yixiangkaocheng was imported in 1766 CE. Thus, the Korean Screen Planisphere with both Old and New Star-charts was certainly made after 1766 CE.

Objectives : Gyeongokgo is a representative herbal formula for longevity in Korean medicine and has been applied to prevent and treat various diseases. Gyeongokgo is recognized as a representative tonic for the Joseon royal family. However, there is yet no legitimate research on how the royal family used Gyeongokgo. The present study aims to analyze Gyeongokgo during the reign of King Sukjong and Gyeongjong with historical records. Methods : Historical records were searched through databases such as the veritable records of the Joseon Dynasty and the daily records of royal secretariat of Joseon Dynasty. Results : During the reign of King Myeongjong, the administration of Gyeongokgo started and expanded to the entire royal family, including the king, queen, and queen mother, by King Sukjong. In the early stage, Gyeongokgo was taken to treat coughing or breathing difficulties. Gradually it was recognized as agood tonic for replenishing energy and blood. Conclusions : The tendency to prefer tonic in the late Joseon Dynasty started during the reign of King Sukjong, and Gyeongokgo began to be used as a seasonal tonic in the fall and winter even though no symptoms appear.

Purpose : The purpose of this article is to make a clarification that Hwang Doyeon(黃度淵) was a official doctor(醫官) who even served as royal doctor(御醫), rather than merely a general doctor who worked in the private sector. The article also attempts to give a new perspective on the medical history about the late period of Joseon(朝鮮) Dynasty. Methods : In researching Hwang Doyeon's master work, the Gains and Losses of Medical Orthodoxy(醫宗損益), the article looks at his clinical medicines. Analyzing the historical records, the article makes an assumption that Hwang Doyeon and Hwang Dosoon(黃道淳), who was selected as an officer to discuss medicine with other medical officers(議藥同參), are the identical person. On this assumption, the article tries to reinterpret the medicine during the later Joseon Dynasty period. Result & Conclusion : The records, including the royal medical treatment records of the Gains and Losses of Medical Orthodoxy, the Daily Records of Royal Secretariat(承政院日記), the genealogy of Changwon Hwangs(昌原黃氏世譜), academic paper and government documents released posthumously, demonstrated that Hwang Doyeon and Hwang Dosoon are the same person. If so, we can have new historical interpretation about medical history of late Joseon Dynasty. First, during the late of Joseon Dynasty, there was an official and active medical knowledge interaction between government and private sector. Second, the Joseon's medicine has been established its own medical system based on the Treasured Mirror of Eastern Medicine(東醫寶鑑), trying to cope with cholera and other contemporary epidemics without relying on Chinese warm disease(溫病) medicine. Third, the Compilation of Formulas and Medicinals(方藥合編), is regarded not only as a must-read medical reading for medical doctors, also playing an important role on popularization of Korean medical knowledge.

Medicinal porridge (藥粥) is made by putting rice or grains into a pot and boiling with water until a semi-liquid texture is obtained. Porridge is digested fast and absorbed by the body. Children or elderly people with weak digestive ability can eat it without difficulty. The authors of this literature focused on utilization of mung bean porridge (Nokdu-juk) based on SeungjeongwonIlgi (承政院日記), which is the daily record of the Royal Secretariat of the Joseon Dynasty from 1623 to 1910. Four cases were found. The first case used mungbean for treating fever diseases (熱症), the second as a meal alternative, the third for wound recovery, and the last case described the culture of the joseon dynasty. According to the actual cases in SeungjeongwonIlgi (承政院日記), mung bean porridge (Nokdu-juk) was actively used to lower fever and strengthen the spleen and stomach. When suffering from the after effects of a malignant tumor or serious liver disease (肝病), an infectious disease, or a serious physical wound, people ate mung bean porridge (Nokdu-juk). It is suggested that mung bean porridge (Nokdu-juk) can be used as an alternative food treatment for the current medical field due to the prevalence of pain-killers and psychotropic drug abuse.

Astronomical data such as calendar day and time of rising/setting of the sun and onset of twilight are essential in our daily lives. Knowing the calendar day of the past is particularly crucial for studying the history of a clan or a nation. To verify previous studies on the calendar day of the Joseon dynasty (1392 - 1910), we also investigated the sexagenary cycle of the new moon day (i.e., the first day in a lunar month) using different sources: results of the calculation by the Datong calendar (a Chinese Calendar of the Ming Dynasty) and data of Baekjungryeok (a Perpetual Calendar - literally, a one hundred-year almanac). Compared with the study of Ahn et al., we have found that as many as 17 sexagenary cycles show discrepancies. In the case of nine discrepancies, we found that the sexagenary cycles of this study are identical to those of the almanacs at that time. In addition, we study six sexagenary cycles by using the historical accounts of Joseon Wangjo Sillok (Annals of the Joseon Dynasty), Seungjeongwon Ilgi (Daily Records of Royal Secretariat), Chungung Ilgi (Logs of Crown Prince), and so forth. We present historical materials supporting the results of this study for the remainder. In conclusion, we think that this study will greatly contribute to the comparison between luni-solar calendar days during the Joseon dynasty and those in the modern (i.e., Gregorian) calendar.

There are many astronomical records of comets in Korean history books. We collected those of the comet that appeared in the winter of the year 1664. These records were written in Daily Reports of the Royal Observatory on Astronomical Events (星變測候單子), Final Reports of the Royal Observatory on An Astronomical Events (天變謄錄), the Daily Records of the Royal Secretariat of the Joseon Dynasty (承政院日記), and the Chronicle of the Joseon Dynasty (朝鮮王朝實錄). We used the Olbers' method for determination of preliminary orbit of the comet, and compared the result with the previous researches. In the Oblers' method the orbit is assumed to be parabolic (e=1). We obtained the following orbital elements: perifocal distance q=1.07\pm0.008AU, perifocal passage time $T=2329165.50\pm0.72$ days, argument of the perifocus $\omega=318^{\circ}.2\pm2^{\circ}.29$, longitude of ascending node $\Omega=85^{\circ}.23\pm2^{\circ}53(J1665)$(J1665), inclination $i=160^{\circ}.28\pm1^{|circ}.56$.

Smallpox and measles might be the typical epidemics through Choson Danasty. Especially Sookjong was the first king who suffered from smallpox during the period of his reign. This study was examined critically focused on the Clinical Records about Smallpox which occurred in the 9th year of Sookjong's reign. The clinical records in Seungjeongwon Ilgi("承政院日記") was the main source and the Annals of the Joseon Dynasty was reffered. It tells us that Sookjong caught infectious disease, smallpox spread in town and the whole process of smallpox. Seungmagalgeuntang(升麻葛根湯) and hwadoktang(火毒湯) were given at the early term for treating Sookjong's smallpox, but later on, Bowontang(補元湯) was given for the treatment of smallpox. It showed us the medical view which placed emphasis on the vital force of human body. A dermatologist, Yoo Sang had joined since the beginning of the treatment and Siyakchung(侍藥廳) was established for Sookjong. Sasunghoichuntang(四聖回天湯) which was Chunyoohyung(全有亨)'s prescription showed us enough clinical experience and the ways of treatments. At the same time, the medical culture at that time was well known through the fact that smallpox was taboo among the royal family.

The life and astronomical activity of Lee Deok-Seong (李德星, 1720-1794) was studied using various historical sources, including the astronomical almanac, Seungjeongwon-Ilgi (Daily records of Royal Secretariat of Joseon dynasty), and the Gwansang-Gam's logbooks during Joseon dynasty (A.D. 1392-1910). We present the results of the study including the following main findings. First, from the investigation of Lee's family tree, we find that a number of his relatives were also astronomers, notably Samryeok-Gwan (三曆官, the post of calendrical calculation). Second, we find that he took part in the compilation of an annual astronomical almanac over a period of at least 16 years. His major achievements in the astronomy of the Joseon dynasty were to establish a new method of calendar-making calculation and to bring astronomical materials to the Joseon court through a visit to China. The Joseon dynasty enforced the Shixianli (時憲曆, a Chinese calendar made by Adam Shall) in 1654 without fully understanding the calendar. So an astronomer and an envoy were dispatched to China in order to master the intricacies of the calendar and to learn as much of Western science as was available in that time and place. Lee Deok-Seong worked at the Gwansang-Gam (觀象監, Royal Astronomical Bureau) during the reigns of King Yeongjo (英祖) and Jeongjo (正祖). As best as we can ascertain in relation with the calculations in the Shixian calendar, Lee visited China four times. During his trips and interactions, he learned a new method for calendar-making calculations, and introduced many Western-Chinese astronomical books to Joseon academia. Lee greatly improved the accuracy of calendrical calculations, even while simplifying the calculation process. With these achievements, he finally was promoted to the title of Sungrok-Daebu (崇祿大夫), the third highest grade of royal official. In conclusion, history demonstrates that Lee Deok-Seong was one of the most outstanding astronomers in the late-Joseon dynasty.
