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 study is to examine the costumes of Gyeokgu in different situations and to suggest when and how they should be used in historical drama. Gyeokgu is a type of polo game that was played in Korea and it was also known as Gyeokbong and Bonghee. The accounts of the game show that it was played during the South-North period as recorded in Balhaego, Haedongyeoksa, and Goryeosa until the Joseon period. The scenes of Gyeokgu have been shown in some historical dramas in order to make the story exciting or to show the life of royalty. The costume of Gyeokgu in the South-North period should be suggested Danryeong(團領), Bokdu, and Haw(靴) in a formal situation. The Gyeokgu in the Goryeo period was a sport for royalty. So the Gyeokgu costume in the Goryeo period was required to be worn with Danryeong(團領), Bokdu, and Haw(靴) for the kings and military officers in the early Goryeo period and with Cheollik(帖裡), Balip or Huklip(黑笠), and Haw(靴) from the middle of the Goryeo period. Women could wear Chima(skirt), Jeogori(blouse), Pyo, and Li(履) when they play Gyeokgu in the Goryeo period in the historical dramas. The Gyeokgu in the early Joseon period was a sport for the kings. After the king of Sejong, the Gyeokgu became a martial art for the military officers. The costume of Gyeokgu in the Joseon period should be Red Cheollik(紅帖裡), Kwadu, Jonglip, Gwangjodae(廣組帶), Sagu, and Haw(靴) as recorded in Muyedobotongji in the 18th century. The kings, servants, and military officers could wear the Cheollik and should be made in the different Git(collar), shape of the sleeves, and the proportion of the upper part and the underpart in each period properly. When the citizens play Gyeokgu, they could wear Geon(巾), Baji(pants), Jeogori(shirt), and Gipsin in the late Joseon period.

This is a basic study of the remaining armors and helmets of the Joseon period for our better understanding and better maintenance of them. For the purpose, this paper shall try to show the present situations of the remaining armor and helmets of the period in Korea, and their typical classification for periodization, and the nomenclature about them. First, to oversee the present situations of the remaining armor and helmets of the period, study was done about the kinds of armors and helmets, their users, and their possessors today. It was found that the exact dates and users were unclear for many cases of the armors and helmets under our consideration. It is understandable when we consider many of them were exported to foreign countries, instead of being well-preserved in Korea upon excavations. Secondly, for their typical classifications for periodization, types were delineated from the pictures and drawings in reference to the periodical changes of them from Korean historical records. The result was that we can find out 4 types of armors, and 3 types of helmets, with their combinations. This shall be usefully applied for the better periodization of the remaining items. Thirdly, we come to the problem of naming of the remaining armors and helmets. For better nomenclature of the remains all the names of the armors and helmets for the Joseon period are collected from historical literature, to figure out some principles of nomenclature for them. I found some discrepancies with the present names of them, and my propositions are suggested to replace them.

We study the manufacturers of the astronomical instruments invented as part of the so-called Ganui-Dae (astronomical platform) project in the reign of King Sejong (1418-1450) of the Joseon dynasty. The main purpose of this project was to compile the Chiljeongsan-Naepyeon, a Korean calendar, that lasted for 5.5 years from 1432 to 1438. Through this project, a total of 17 astronomical instruments such as the armillary sphere, celestial globe, and auto-striking clepsydra were developed. It is generally known that most of them were manufactured by Lee Cheon (李蕆, 1376-1451) and Jang Yeong-Sil (蔣英實, fl. 1423-1442). In this study, we investigate the accounts of the Veritable Records of King Sejong, Munjong, and Sejo, focusing on the inscription written out to memorize the completion of the Ganui-Dae project. We found that at least 12 persons took part in manufacturing the astronomical instruments of the Ganui-Dae project. Lee Cheon was involved in the production of four instruments, while Jang Yeong-Sil was involved in two; therefore, it seems that the achievement of Jang Yeong-Sil was overestimated. We also found that Jeong Cho (鄭招, ?-1434) was a scientist and Lee Cheon was an engineer in the early phase of the Ganui-Dae project, while King Sejong and Yi Sun-Ji (李純之, 1406-1465) played major role in the late phase. According to our study, King Sejong and Yi Sun-Ji were involved in the production of at least seven and five instruments, respectively. In conclusion, we believe that this study will be helpful to understand the practical manufacturers of the astronomical instruments invented during the Ganui-Dae project in the Joseon dynasty.

We analyzed the manufacturing procedure, specifications, repair history, and details of celestial movements of the water-hammering type $Honsang$ (celestial globe). Results from our study on the remaining $Honsangs$ in China and Japan and on the reconstruction models in Korea were applied to our conceptual design of the water-hammering type $Honsang$. A $Honui$ (armillary sphere) and $Honsang$ using the water-hammering method were manufactured in $Joseon$ in 1435 (the 17th year of King $Sejong$). $Jang$ $Yeong-Sil$ developed the $Honsang$ system based on the water-operation method of $Shui$ $y{\ddot{u}}n$ $i$ $hsiang$ $t'ai$ in China. Water-operation means driving water wheels using a water flow. The most important factor in this type of operation is the precision of the water clock and the control of the water wheel movement. The water-hammering type $Honsang$ in $Joseon$ probably adopted the $Cheonhyeong$ (天衡; oriental escapement device) system of $Shui$ $y{\ddot{u}}n$ $i$ $hsiang$ $t'ai$ in China and the overflow mechanism of $Jagyeongnu$ (striking clepsydra) in $Joseon$, etc. In addition to the $Cheonryun$ system, more gear instruments were needed to stage the rotation of the $Honsang$ globe and the sun's movement. In this study, the water-hammering mechanism is analyzed in the structure of a water clock, a water wheel, the $Cheonhyeong$ system, and the $Giryun$ system, as an organically working operation mechanism. We expect that this study will serve as an essential basis for studies on $Heumgyeonggaknu$, the water-operating astronomical clock, and other astronomical clocks in the middle and latter parts of the $Joseon$ dynasty.

TThis study was undertaken to make trial costumes of ball jointed dolls for promoting the beauty of Korean cultural product with historical research of upper class ladie's costume from late Goryeo to early Joseon, the very unknown period in the Korean costume history. The ladies' costume from late Goryeo to early Joseon are characterized by their full silhouette, fusion with clothings of Yuan and Ming, revival of early Goryeo styles, well-developed weaving skill of ramie, a showy costume from Buddhist civilization. After investigation of researcher with literature, painting, and relics in 13-14C, 8 clothing items were outsourced totally. Items were formed as a set concept, but consumer can choose each costume as an single item and can make varied mix also. Dart, small ties, and thick fabrics were used in doll costumes partly because ball jointed doll's body has different characteristics from that of human beings. Developing research of manufacturing company's system for ready-made product remains to be considered in the future.

The Annals of Joseon Dynasity record a significant damage of tsunami in the east coast of Gangwon Province on August 29, 1741. The tsunami occurred near Oshima-Oshima island off the southwestern coast of Hokkaido, Japan, and this study conducted simulations of a ray-tracing model to analyze the effects of the tsunami on the East coast of Korean Peninsula at that time. Model results were calculated using four different depth dataset (ETOPO2m, ETOPO1m, SKKU1m, and GEBCO15c), and results using the highest resolution GEBCO15c showed the best description of the damage recorded in the Annals of the Joseon Dynasty. Based on such, the travel time and paths of the tsunami that reached the main regions of Gangwon Province are presented in detail.

The necessity of the Toi-Maru has increased greatly in order to enter to the building or to move conveniently in the building after the mid-Joseon period, when the combination of On-dol Ma-ru began to be universally used. According to this process, the 3-Dori type upper structure is thought to have undergone the typological changed by securing a more stable space of Toi-Maru In cases where a relatively large girder was used, it is often the case that the space is divided using a pillar to place a Toi-Maru on the front. However, it is difficult to find a case where the width of the Toi-Maru exceeds 1meter due to its structural limit. The type that made additional Toi-girder to overcome the spatial constraint of this structure and replaced the method of former typology after Mid-Jpseon period. In case of 5-Dori type, Toi-Maru installed in between high post and Toi post in early period. In these type, the width of Toi-Maru was subordinated by the location of milled Dori of roof structure and sometimes it became too excessive. 5-Dori type with Pyon-ju occurred to overcome these restriction between the width of Toi-Maru and the location of milled Dori of roof structure. Not a few remains of Mid-Jpseon period keeping the evidences of changing process of roof structure provoked by Toi-Maru installation. The consistent process of Toi-Maru installation and structural adjustment will be focused to consider the attempt to spatial requirement and architectural reaction in Mid-Joseon perid.

The National Museum of Korea conducted conservation treatmenton the armor in its collection for the purposes of public display and appropriate preservation. This was preceded by a literature study on the types and features of the armor in order to collect basic data for secure and accurate conservation treatment. The literature study found that during the Joseon dynasty, armor was named in reflection of precise details including the color, material, status of the wearer, and even the certain parts of a suit of armor. In general, the name of armor includes the details in the order of color, underlying textile, and scale material (e.g., iron, leather). The former part of the name presents the features of the garment and the latter part refers to the material of the scales or the status of the wearer. The study also found that main materials used in armor include textiles, leather, and metal, and armor can be classified by the materials of the scales-e.g., metal armor (鐵甲), leather armor (皮甲), paper armor (紙甲), paper-and-fabric armor (淹心甲), silk armor (緞甲). Joseon-period armor can also be classified into four types according to its structure and the method of wearing, and overcoat(袍)-style armor was the most widely used in the period following the Japanese Invasion of Joseon (1592-1598) through the late nineteenth~early twentieth century. Overcoat-style armor was commonly worn by infantry, and the four examples of armor with leather scales at the National Museum of Korea belong to this category.

This study finds an interesting fact that five symptoms (smallpox, postpartum pain, eye disease, swollen symptom and parasite infection) mentioned in Ryu Ei-Tae Medicinal Tales and his prescriptions (steamed rice, loess, soybean sprouts, cinnabar, radish, sesame oil and pork) were dramatized on the basis of traditional Korean medicinal knowledge in the Joseon Dynasty. Based on the study of experience-based medicinal literatures popular in the Joseon period, it is confirmed that the prescriptions are actually effective. Also it is inferred that popular diseases at that time were abscess, difficult baby delivery, postpartum pain and parasite infection, which were regarded as almost incurable diseases to ordinary people. These stories also showed destitution of common people who could not afford to buy medicines at that time. As shown in the Ryu Ei-Tae Medicinal Fable, many people might try various ordinary materials around them such as soil or nose wax. One of the outcomes of this study is that the fact that the tales mentioned common materials easy to get in the surroundings such as steamed rice, sesame oil, soybean sprouts or radish could be interprets as care and consideration of medicinal doctors for ordinary people at that time.
