In this paper, we report the analysis of Korean historical records on the periodic Halley's comet according to the period (i.e., the Three Kingdoms, Goryeo Dynasty, and Joseon Dynasty) using various sources such as the Samguksagi (The History of the Three Kingdoms), Goryeosa (The History of the Goryeo Dynasty), and Joseonwangjosillok (The Annals of the Joseon Dynasty). With regards to the apparition time of the comet for each return, we referred to the works of Kronk. For the Three Kingdoms period, we could not find any record relevant to Halley's comet from the Samguksagi. Furthermore, we examined the suggestion that the phenomenon of "two Suns" which appeared on April 1, 760 (in a luni-solar calendar), as recorded in the Samgukyusa (The Legends and History of the Three Kingdoms), indicates an instance of the the daytime appearance of Halley's comet. In contrast with the Three Kingdoms period, we found that all returns of Halley's comet are recorded during the Goryeo Dynasty, although others have questioned some accounts. We also found that the appearance of Halley's comet in 1145 is mentioned in a spirit-path stele made in 1178. For the Joseon Dynasty period, we found that all apparitions of the comet are recorded, as with the Goryeo Dynasty, except for the return of 1910, at which time the former dynasty had fallen. In conclusion, we think that this study will be helpful for understanding Korean historical accounts on Halley's comet.

It has been generally known that Datong-li (a Chinese calendar in the Ming dynasty) was first introduced into Korea in the nineteenth reign of King Gongmin (1370) of the Goryeo dynasty and lasted to the third reign of King Hyeojong (1652) of the Joseon dynasty. This understanding is based on the records of Goryeo-sa (History of the Goryeo dynasty) and of Seoungwan-ji (Official book of Seoungwan)/Jeungbomunheon-bigo (Explanatory Notes of Library Document). To verify the period of the use of Datong-li in Korea, we develop a Fortran code to calculate the calendar day by Datong-li and also investigate historical literatures and extant almanacs. As a result, we find the possibility that Datong-li had been in use since 1389 at least. However, we cannot confirm whether Datong-li was first enforced in 1370 or not. On the other hand, we confirm that Datong-li was used until 1653 and reintroduced during the period from 1667 to 1669. Also, we find that previous studies had some errors in the sexagenary cycle of the real first day of a month. We think that this study will contribute to understanding the calendrical history of the Joseon dynasty.

This paper aims at researching on the substantial characters of the memorial address, namely the mookseo-myeongs(墨書銘), written at the members of the wooden buildings in the late period of Goryeo Dynasty and the early period of JoseonDynasty. In this paper, I pursued to declare the systematic origins by the comparison the Buddhist buildings with the other buildings, on the focused the written patterns. Furthermore, I tried to examine the transitional trends in the late period of Joseon Dynasty. The results are as follow: First, it is supposed that the mookseo-myeongs of the Buddhist buildings were not used for the a memorial address for the ceremony of putting up the ridge beam, so to speak the sangryang-muns(上樑文), but the prayer address(發願文) to memorize the donations of the believers for the constructions. Second, it is supposed that 'the short sangryang-muns' were originated in the mookseo-myeongs of Buddhist buildings and the other ancient prayer address. In the late period of JoseonDynasty, those were established in the formal literary styles. Third, to the early period of JoseonDynasty, 'the long sangryang-muns' were partially used in the several royal palaces. In the late, those were widely used not only in the royal palaces but also in Buddhist buildings, but those literary patterns were rarely changed from the former types.

In this paper, we analyzed Korean historical records of the periodic comet Halley in three periods (Three Kingdoms, the Goryeo dynasty, and the Joseon dynasty) using various sources such as Samguksagi (History of the Three Kingdoms), Goryeosa (History of the Goryeo Dynasty), and Joseonwangjosillok (Annals of the Joseon Dynasty). To determine the apparition time of the comet at each return, we referred to the works of Kronk. For the Three Kingdoms period, we could not find any record relevant to Halley's comet from Samguksagi. Instead, we examined the suggestion that the phenomenon two Suns appearing on April 1, 760 (in a luni-solar calendar), which is recorded in Samgukyusa (Renaissance of the Three Kingdoms), indicates an appearance of comet Halley during the daytime. In contrast, we found that all the returns of Halley's comet during the Goryeo dynasty are recorded, although some accounts are questioned. In addition, we found that the appearance of Halley's comet in 1145 is also mentioned in a spirit-path stele made in 1178. For the Joseon dynasty period, we found that all the returns of the comet are recorded, as with the Goryeo dynasty, except for the return of 1910, in which the former dynasty fell. In conclusion, we think that this study will be helpful for understanding Korean historical accounts of Halley's comet.

The construction period of the ondol (Korean floor heating system) at Hoeamsa Temple Site is known as Joseon. The main reason is that a large number of remains in the Joseon era were excavated from the ondol floor with an all-around ondol method. This article partially accepts the theory of the creation of Ondol at Hoeamsa Temple Site during the Joseon Dynasty and suggests a new argument that some Ondol remains were built during the Goryeo Dynasty. The grounds for them are as follows. First, through the building sites consistent with the arrangement of the Cheonbosan Hoeamsa Sujogi (天寶山檜巖寺修造記, Record of Repair and Construction of Hoeamsa at Cheonbosan Mountain), it is highly likely that the ondol remains as a basic floor was maintained during the reconstruction period in Goryeo. Second, the all-around ondol method of the Monastery Site has already been widely used since the Goryeo Dynasty. Third, some ondol remains consist of "Mingaejari" and "Dunbeonggaejari," which were the methods of the gaejari (which dug deeper and stayed in the smoke) in the pre-Joseon Dynasty. Based on the above evidence, this study argues that the building sites such as Dongbangjangji, Seobangjangji, Ipsilyoji, Sijaeyoji, Susewaryoji, Seogiyoji, Seoseungdangji, Jijangryoji, and Hyanghwaryoji were constructed during the late Goryeo Dynasty.

The purpose of this study is to examine the pieces of 100 fabrics excavated from unknown woman's tomb Incheon, by analyzing woven methods, names of the fabrics, the kinds and the shapes of the patterns. The characteristics to assume the period of the fabrics are as follows. The geumsundan which was woven peacock insignia at chest and back area was excavated for the first time from the tomb of Joseon. Peacock insignia woven with satin weave using supplementary golden wefts, wrapped gold thread. These kind of fabrics were usually imported in the $15^{th}$ century, according to the old documents, 'Nogeoldae' 'Joseonwangjosilrok' written at the end of Goryeo or early in Joseon. Thus, these relics are from about $15^{th}$ century. From this tomb, the mixture fabric of cotton and ramie are excavated. According to another excavated cases, the mixture fabric of cotton and ramie appears from the period before the Japanese Invasion of Korea in 1592, and after the invasion, there are usually mixture fabric of cotton and silk. This also tells that these fabrics show the characteristics of those from the early period of Joseon Dynasty. The rounded patterns of Jangot is only shown from the fabrics of late Goryeo Dynasty, and the cloud pattern of an upper garment with a squared neckline is shown from the early Joseon Dynasty. So, the patterns from these excavated costumes are ranged from the late Goryeo Dynasty to the early Joseon Dynasty. To assume the period through the overall study above, these relics show the characteristics of the $15^{th}$ century fabric.

The late Goryeo and Early Joseon period marks the development of Hyang-yak medicine in medical history in Korea. There have been not a few outcomes in organizing Hyang-yak medicine through the hitherto research works, but there has hardly any attempt to view the medicine in the late Goryeo and Early Joseon period from a different standpoint besides Hyang-yak. This writer, in the middle of doing research on 'Book for Alimentotherapy' named "Sikuisikgam", came to know that not a few parts of this book were quoted in a large volume of "Biebaekyobang" in the late Goryeo, "Hyangyakjipseongbang" which compiled the early Joseon Hyangyak medicine, "Uibangyuchi" which wrapped up the medical knowledge in East Asia before the early Ming Dynasty, and "Sikryochangyo" which was a representative book for alimentotherapy in the early period of Joseon Dynasty. The reason that the representative medical books written in the period of Late Goryeo and Early Joseon thought much of the knowledge contained in "Sikuisikgam" is that they showed a great concern for prevention and treatment of diseases through alimentotherapy. When we say that Hyangyak medicine, which has provided the Late Goryeo and Early Joseon medicine, bases its standard on 'Regionality' and 'Properties of Medicinal ingredients', then alimentotherapy puts its focus on a 'Remedial method' itself. As for food, they might have given priority to the food that was easy to get nearby, so there is no way for alimentotherapy but to have the realm which is overlapped with Hyangyak medicine in some measure, That's the very reason why alimentotherapy has remained inseparate from Hyangyak medicine. Through 'Alimentotherapy' and Late Goryeo and Early Joseon medical books, this writer thinks that it might be possible for us to take a view of the Late Goryeo and Early Joseon not only from the perspective of Hyangyak medicine but also from a new perspective of so-called alimentotherapy.

This study aims to examine the cutting traces remaining on the bracket tie beams of Sungnyemun gate, identifying the tools employed during the late Goryeo to early Joseon periods by specific processes, and deliberating on the timber shaping techniques utilized in advanced architectural construction during the late Goryeo to early Joseon eras. Through the research, it was confirmed that in the production of Sungnyemun Gate's bracket tie beams during the 14th to 15th centuries, both the timber splitting and ripsawing methods were used in conjunction. Moreover, the wood finishing process revealed the use of a plane. It can be inferred that the characteristics of the plane used during that time were not significantly different from those observed in the later period of the Joseon dynasty. The ripsawing and plane finishing techniques were evident in various parts of the bracket tie beams of Sungnyemun gate across the reigns of king Taejo and Sejong, indicating that the techniques involving ripsaw and plane were already prevalent in the late Goryeo period. Consequently, it can be inferred that the ripsawing and plane finishing techniques might have been applied in the construction of prominent government buildings in Hanyang(Seoul), including Gyeongbokgung Palace, and in the residences of royalty and nobility after the establishment of the Joseon dynasty.

This study analyzed the characteristics of Korean traditional plain weave excavated from Sang-go period to Joseon Dynasty. To do this, this study classified the Korean traditional plain weave into fiber types(cotton, hemp & ramie, plain weaved silk), analyzed and compared the thickness, twist type of yarns and density by times. First, in characteristics of cotton, the average and maximum density of Joseon Dynasty were higher than those of Goryeo, twist type was mainly s-twist and the density of warp was higher than that of weft. Second, the maximum density of hemp & ramie was found in era of Three Kingdoms of Korea. In common characteristics of hemp & ramie, twist type was mainly s-twist(sometimes non-twist) to the Three Kingdoms of Korea and was changed into non-twist from the Goryeo. The density of warp was higher than that of weft in common. Generally, the average density of ramie was higher than that of hemp. Third, in the characteristics of plain weaved silk, twist type was mainly non-twist(sometimes s and z-twist) from Sang-go period to Joseon Dynasty. Warp-faced ribbed tabby was excavated in Goryeo, the average density of warp-faced ribbed tabby was higher than that of other fiber types plain weave. Generally, in all fiber types, the density of warp was higher than that of weft.

This paper examines the material culture of the Goryeo-Joseon Period through changes in the design and crafting of the earpick. In Chapter 2, terminology regarding earpicks is presented, and the culture of using earpicks is examined through fragmentary literature of the late Joseon Dynasty. Earpicks were first a personal hygiene tool, and, secondly, they played a symbolic role as a style accessory used by men, analogous to the fan carried by women of the time. In Chapter 3, earpick form are classified by period, and characteristic decorative techniques for each form are examined. During the Goryeo Dynasty, earpicks were sanitary tools, and, according to their form, they were classified into single and complex types. From Unified Silla to Goryeo, there is an angled type of connecting rod, and in the Goryeo period, there appeared earpicks with colorful decorations on the handle, completely forged earpicks with a thin and long shape, and earpicks which were part of multitools. Common decorative techniques include line expression, gold plating, cheophomun on the background, and inlay. Earpicks of the Joseon Dynasty are classified into sanitary tools or ornaments, according to their purpose of use. Sanitary tools are divided into single type and complex type, and earpicks used as ornaments include headdress, norigae, and sunchu. For earpick accessories, headdresses and norigae were used for women, and sunchu was used for men. The decorative techniques of earpicks during the Joseon Dynasty were mainly seen in the headdress earpicks. They were decorated with various colors in the Cloisonné method or bejeweled. Research on everyday tools among crafts is lacking; greater attempts to read the flow of time and approaches to material culture through everyday tools should be made.
