The purpose of this essay is threefold. First, to highlight research of Seonmin KIM, whose 2006 Ph.D. dissertation elucidates complex relationships among Ming China, Choson Korea, Tokugawa Japan, and mountainous ginseng-producing "borderlands" between Korea and China; her story concludes with the remarkable rise of a borderlands power that overthrew Ming China, there-by establishing dominance that lasted into the $20^{th}$ century - the Qing Dynasty. A second purpose is to showcase application of a non-standard-model - the Hydraulic Metaphor - that elucidates economic components of Professor KIM's history via visual and intuitive mechanisms designed to be understandable for non-specialists. Last, an outline of East Asian history is placed within context of centuries of monetary evolution that eventually yielded the late-$16^{th}$-century birth of globalization.

"Gup Yu Bang" is the first Korean book that specialized in pediatrics. It was written by Jo Jeong-jun on the 25th year of King Young Jo in the Choson dynasty. He quoted a lot of information from "Yi-Hak-Yip-Mun" by Yi-cheon in the Myung dynasty and "Xiao Er Yao Zheag Zhi Jue" by Qian Yi in the Song dynasty, but he added his own opinions and clinical experiences to the book. In addition to that, the book explains not only symptoms and prescriptions but also the etiology and pathology of children's diseases. In particular, he showed a great deal of creativity in his book called "Dong Bang Six Fu's Qi Principle" After studying "Gup Yu Bang", I have drawn the following conclusions. 1. Prevention is more important than treatment in pediatrics. 2. When we make a diagnosis, facial inspection has priority. 3. In terms of treatmemt, Wu zang is a general rule. Therefore, we should focus on Wu zang and Pi Wei. 4. The following terms definition symptom cause prescription clinical example prevention are to be explained with reference to the nature or symptoms of the disease. 5. We can see that smallpox was more widspread than the measles in the period of King Young Jo. 6. Even though he was influenced by "Yi-Hak-Yip-Mun", "Xiao Er Yao Zheag Zhi Jue", and "Dong eui bo gam", his own explanation is clearer in his book called "Gup Yu Bang" which is based on his own clinical experiences. 7. "Gup Yu Bang" is a practical and experiential book.

The objective of this study is to examine the costumes of the period covered in the writings of Shilhak (practical science) scholars and to research the history of costumes and their characteristics by examining how they are worn in genre paintings which are said to describe the actual life of the period. This should be studied in order to correctly establish the history of costumes. To begin with, through the writings of the representative Shilhak scholars who are thought to have affected the changes in ordinary costumes for woman, this study examined how ordinary woman of the period looked in their costumes and how they regarded various costumes they had. Then, how their viewpoints of costumes influenced ordinary costumes was investigated. Not only relics, but what was commonly worn, as they appeared in the genre paintings that contain information about daily living of that period, were researched chronologically. The results of this study showed that the change in ordinary costumes for woman in the late Chosun period was affected by Shilhak scholars who had ideologies of Shilsakusi (use of positive methods in studying), Yiyonghusaeng (the promotion of commerce and industry and the development of techonologies), and Ky ngsech'iyong (pursuit of stability in a rural economy). Moreover, after those changes there were many more changes. However, the criticism of costumes of that time and the will of revolution affected some time, costumes changed directly. The forms of the costumes had been changed in a variety of ways following the tendencies of the times, but the origin of today's hanbok (Korean traditional dress) had already been fixed in the late Choson period. Yet, today's hanbok are for special occasions, not worn as ordinary clothing. Thus, there are several reasons why the hanbok is not suitable for daily life. One of the reasons is that Korean could not cope with the western costumes indepen-dently imported during Japanese occupation in the last period of the Choson Dynasty and con-tinuing the Japanese Colony. Thus, only a part of the ordinary costume of the late Choson period has remained until now.

We have reproduced the records of lunar occultation recorded in the History of Three Kingdoms(삼국사기), the History of the Koryo Dynasty (고려사), the Annals of the Choson Dynasty (朝鮮王朝實錄), the Daily Records of Royal Secretariat of the Choson Dynasty (승정원일기), and obtained the epochs of their realizations. We analysed these results to understand how the system of hours had been kept and when a day began. During most of the periods encompassed by these annals, the 12 double hours(12진각법) and the system of 100 divisions of the day (백각법) had been used when the lunar and the solar eclipses were calculated by royal astronomers. In these systems, the starting point of a day is midnight. On the other hand, the five watch system of hours (경점법), in which a night is divided into five watches, was also used. In this system, a day begins at the sunrise. We found that the traditional twilight, called dusk and dawn (혼명) and used in the east Asian countries, largely corresponds to the nautical twilight in modern concepts. This fact means that the Korean expressions and words for time system in every day life had originated form the five watch system of hours. We pointed out that the sunrise and sunset were convenient boundary lines to ancient astronomers, as well as to farmers in the agricultural society. Our results can be used to determine the exact epoch of each astronomical record in chronicles.

Myun Bok originated in China was introduced into Korea in ancient times. Some evidences show that it had settlled down as our own official robe already under Koryo Dynasty. And Koryo made her own regulations on Myun Bok. Kook Cho O Rye Eui(國朝五禮儀) of Choson Dynasty has comparatively detailed explanations on the way of cutting and shapes and materials. And the regulations are modeled after those of Ming China. But it has been impossible to know whether the regulations of Kook Cho O Rye Eui were strictly kept or not, because we have not enough remains through which to see it. And then we got very useful materials, Eui kue(儀軌), which are well known but have not been used in studying the history of costumes. Every Kook Chang Do Gam Eui Gue(國葬都監儀軌) have the provision of the so-called Pok Wan(服玩) set which includes the imitations or the full set of Myun Bok. And the provisions show us the illustrations colored in detail which help us understand the real shapes and the transformations of Myun Bok. After surveying the Pok wan provisions, author arrived at conclusions as follow; 1) Myun Boks are not always made in the same shape and colors. 2) The Provisions of Kook Cho O Rye Eui were not always kept strictly due to the lack of detailed directions.

Sinsuntaeeuljagumdan is a medical book written by Jong-jun Lee, who was an government official in Yonsan-gun period in Chosun dynasty. This book has importance in medical history, as it was the first privately published medical book in early Choson dynasty, and written by an bureaucratic gentry, not by a professional doctor. Three versions of this book remain, among which Sungam version is printed and closest to the original, while Kyoto version is facsimile manuscript of the Sungam version. The contents of the book can be divided into three subsections, i.e. constituents and making instructions, applicable symptoms and adminstration directions, and medical records and episodes. The medical records, of these three sections, are total 8 cases, with a great value as the first ever medical record in korean history.
