The Annals of the Joseon Dynasty are important records registered in UNESCO. This paper proposes a method to analyze big data by examining the frequency of words in the Annals of the Joseon Dynasty translated into Korean. When you access the Annals of the Joseon Dynasty from an Internet site and try to investigate the frequency of words, if you directly access the source included in the page, the keywords necessary for the HTML grammar are included, so that it is difficult to analyze big data based on the frequency of words in the necessary text. In this paper, we propose a method to analyze the text of the Annals of the Joseon Dynasty using Java's Jsoup crawling function. In the experiment, only the Taejo part of the Annals of the Joseon Dynasty was extracted to verify the validity of this method.

This study is a review of Ipsik, the decorative ornaments found on traditional Korean horsehair hats, known as Ipja, which were worn by men in the late Joseon Dynasty. In a broad sense, Ipsik are regarded as men's accessories. Therefore, although this study is limited to Ipja, it is significant in the sense that it delves into one facet of men's accessories in detail. Because the appearance of the horsehair hats was rather mundane, Ipsik and Ibyeong were added as ornaments. During the Joseon period, various types of hat ornaments existed, named Maeksu, Hosu, Gongjagu, Sangmo, Jingdori, Ijeon, Guyeongja and Ibyeong. A person's social ranking and class could be discerned by the materials used in the Ipsik he wore. Jeongja, a decorative accessory used to attach to an official's hat, was institutionalized in the sixteenth year of King Gongmin's reign(1367), during the Goryeo Dynasty, prior to the founding of China's Ming Dynasty in 1368, which indicates that Jeongja were influenced by the Yuan Dynasty. A record in Lao Chi'ta (a textbook of spoken Chinese estimated circa 1346) confirms this fact. Based on a review of literature, we learn that just as with Ongno, Jeongja were imported for use on Jeonrip, a soldier's hat. During the Ching Dynasty, Jeongja were further subdivided and more exquisitely designed. On the other hand, in the Joseon Dynasty, a rule was handed down mandating that a royal prince use gold for his jeongja, officials at third rank or above use silver, and governors, commanders in chief, and officials with the Office of Inspector General and Office of Censor General use jade. Inspectors were permitted to use crystal. Jeongja made of jade were used until the late Joseon Dynasty.

In this study, we investigated the time signal devices of Deungnu (circa 1270) and Gungnu (1354), the water clocks produced during the Yuan Dynasty (1271-1368). These clocks influenced Heumgyeonggaknu (1438) of the Joseon Dynasty (1392-1910), exemplifying the automatic water clocks of the Yuan Dynasty. Deungnu, Gungnu, and Heumgyeonggaknu can be considered as automatic mechanical clocks capable of performances. The Jega-Yeoksang-Jip (Collection of Calendrical and Astronomical Theories of Various Chinese Masters) contains records of Deungnu extracted from the History of the Yuan Dynasty. We interpreted these records and analyzed reproduction models and technical data previously produced in China. The time signal device of Deungnu featured a four-story structure, with the top floor displaying the four divine constellations, the third floor showcasing models of these divinities, the second floor holding 12-h jacks and a 100-Mark ring, and the first floor with four musicians and a 100-Mark Time-Signal Puppet providing a variety of visual attractions. We developed a 3D model of Deungnu, proposing two possible mechanical devices to ensure that the Time-Signal Puppet simultaneously pointed to the 100-Mark graduations in the east, west, south, and north windows: one model reduced the rotation ratio of the 100-Mark ring to 1/4, whereas the other model maintained the rotation ratio using four separate 100-Mark rings. The power system of Deungnu was influenced by Suunuisangdae (the water-driven astronomical clock tower) of the Northern Song Dynasty (960-1127); this method was also applied to Heumgyeonggaknu in the Joseon Dynasty. In conclusion, these automatic water clocks of East Asia from the 13th to 15th centuries symbolized creativity and excellence, representing scientific devices that were the epitome of clock-making technology in their times.

Jing-Yue Jang(張景岳, 1563{\sim}1640$), a medical scalar in the late Ming(明) Dynasty wrote many books such as Leijing(類經), Zhilyilu(質疑錄) and Jingyuequanshu(景岳全書). He was also famouse for the concept of 'Warming and Recuperating(溫補)' and 'Syndrome Differantation Treatment(辨證論治)', Jingyuequanshu was written between 1636 and 1640, and first published in 1700, It can be said that the book was imported from Ming Dynasty of China to Chosun(朝鮮) Dynasty, in what is now South Korea. between 1713 and 1724 In eighteen century. the book was quoted in Euimunbogam(醫門寶鑑), Jejungshinpyun(濟衆新篇) and Magwaheotong(麻科會通). In nineteen century. the book was quoted in Euijongsonik(醫宗損益), Bangyakhappyun(方藥合編), Dongeuisusebowon (東醫壽世保元) and Euigamjungma(醫鑑重磨). The number of quoted prescription and thesis during in nineteen century. is much more than that of eighteen century, Specifically, there are thirty prescriptions of Xinfangbazhen(新方八陣) in Bangyakhappyun, and the concept of 'Nourishing Yang(扶陽)' in Euigamjungma is also based upon Jing-Yue's thesis, This fact shows that we cannot consider the medicine of the late Chosun Dynasty as an abridgement of Dongeuibogam(東醫寶鑑). It is also said that the study focusing on medical books imported from China to Korea in this period is related to understanding the medical progress in the late Chosun Dynasty and the medical intercommunication between Korea and China.

Ip-yeong or gat-keun decorate heuk-rip, supplementing its simplicity. When the wind blew, a dynamic beauty was created, especially if the gat-keun was made with long straps of jade or silk. Basically, ip-yeong was a practical chin strap to hold the gat tight on the head. Commoners made ip-yeong by folding cotton cloth or fine gauze. However, as available materials became diversified, people used cloth, jade, agate, amber, coral, gold medallion, rock crystal and bamboo as well, juk-yeong, which was made with bamboo, became popular especially when Heungsun Daewon-gun, the father of King Kojong, decreed that people wear simple clothes. Most records concerning ip-yeong in Chosun-wangjo-shillok, the authentic record of the Joseon Dynasty, are related to forbidding a sumptuous life. The book also suggests that ip-yeong was bestowed by the king or was offered to foreign diplomats as gifts. Ip-yeong doesn't seem to be a unique system for Korea. Based on portraits or paintings where ip-yeong can be found, it seems to have been widely used during the Yuan dynasty and the Goryeo dynasty. The system disappeared in China as the Ming Dynasty was established, but it remained in use in the Korean Goryeo dynasty and through the Joseon. Literature suggests that the same materials were used for ip-yeong from the beginning of Joseon to the end of the dynasty. Guyeongja refers to a ring that connects an ipja to a chin strap. Guyeongja made with silver, bronze and jade still remain. In gungjungbalgi, the royal court inventory book, records of imogarye can be found (1882), where ten pairs of pure gold strap rings and ten pairs of gold-plated ones were used for a royal wedding.

This study mainly inquired characteristics and changes of 'Chang-aelgool' through 38 cases(with 161 Ssang-chang) of annex and pavillion buildings in Yeong-nam region which are built during the Chosun dynasty. The method of inquiry included actual survey of windows along with bibliographical research, and the results are as below. First, through the discovery of the term 'Chang-aelgool' as an indication of the window-forming frame in 'YeongGeonUiGwe'(1680 A.D), it is apparent that the term 'Chang-aelgool' was widely used in Korea from the late 17th century. Second, the 'Chang-aelgool' of study objects are classified into 4 categories. Type I and II are comprised of mitre-joints which cover the 4 corners of 'Chang-aelgool' and mainly used in building annex and pavillion buildings during the early period of the Chosun dynasty. Type III was widely used during the early and middle period of the Chosun dynasty and drastically dropped in number during the late period of the dynasty. Type IV is comprised of mitre-joint of the upper-half, tenon-jointing of the lower-half and widely used in annex and pavillion building during the late period of the Chosun dynasty. Third, the form of 'Chang-aelgool' has changed from rectangular form with longer width during the early period of Chosun dynasty to square form during the middle period and eventually ended up as a rectangular form with longer height during the late period of the dynasty. Fourth, it is considered that while mullion which is located in the center of 'Chang-aelgool' was mainly used around the main floored room during the early period of the Chosun dynasty, became commonly used in main floored room and 'ondol' rooms during the middle period and drastically dropped in number from then and ended up being not in use after the mid 18th century.

After the unification of Three Kingdoms, Silla Dynasty had been on the prosperity with continuous population growth during approximately 120 years. However, Unified Silla Dynasty experienced 11 times of famine and bad year by frequent droughts during 50 years since the late 8th century, and these caused to political, economic and social changes. It is evident that Silla Dynasty slowly declined by the droughts and famines, although ancient records described as still on glory days. Since then, national power of Unified Silla Dynasty was abruptly weakened by migration of residents, and 9 times of rebellion or revolt occurred during 50 years in the late 9th century. As a result, political and social agitations reached the maximum. These led to the collapse of the Unified Silla Dynasty, and King Gyeongsoon handed over the dynasty to King Wanggeon, a founder of Goryeo Dynasty. These resulted from the 500-year-cycle droughts and human activities that seriously devastated the vegetations by using trees as an energy source for hundreds of thousands people during several centuries. The devastation of vegetation destroyed farm lands and led to large changes in river and groundwater systems, and eventually, increased damages by droughts.

In Korean historical documents, there are a great number of the records for various astronomical events. In particular, historical documents of the Joseon dynasty also have the records containing observational data by an astronomical instrument. However, a quantitative analysis for the accuracy of observational values have never been studied, although there are some studies on the truth of the records themselves. Hence, we investigated observation errors during the period of the Joseon dynasty from the records of Joseon-Wang-Jo-Sil-Lok (the Annals of the Joseon Dynasty) and Seung-Jeong-Won-Il-Gi (Daily Records of the Royal Secretariat). We used the records of the Mars, supernova 1604, and Halley's Comet, and found that observational values before the Hideyoshi invasions in 1592 are relatively more accurate than those after then. However, because the number of cases used in this study is small, we think that more studies are needed to confirm our results. Nonetheless, we reckon our work will be of service to understand astronomical records of the Joseon dynasty.
