In this paper, we study the structure of the Daegyupyo (大圭表, Large Gnomon) of the early Joseon dynasty. A Gyupyo (圭表, Gnomon that is Guibiao as pronounced in Chinese) is composed of a Pyo (表, Biao as pronounced in Chinese) making a shadow and a Gyu (圭, Gui as pronounced in Chinese) measuring its length. It is known that the Daegyupyo with the 40-feet height was constructed between the sixteenth to seventeenth year of the King Sejong reign (1444 - 1445) on the basis of the record of Yuanshi (元史, the History of the Yuan Dynasty). By analyzing historical documents such as Joseonwangjosillok (朝鮮王朝實錄, the Annals of the Joseon Dynasty), Yuanshi, and Jegaryeoksangjip (諸家曆象集, a work written by Sunji Lee), we found a possibility that the Ji (池, a pond) on the Gyu was located in the north side of the Pyo. This structure is different from that in previous studies, but is in a good agreement with that of the 40-feet Guibiao remaining in Dengfeng (登封) of China. Regarding to the Hoengyang (橫梁, cross-bar), we suggest that it was set up by double 5-feet supporting arms apart from the north tip of the Pyo in the radial direction. The 3:4:5 ratio in a rectangular triangle was used to place the Heongyang on the top of the Pyo at a distance of 4-feet (3-feet) in the vertical (horizontal) direction. We also discuss the structural problem when the Hoengyang is positioned apart from the top of the Pyo by supporting arms. In conclusion, we think that this study should be useful in restoring the Daegyupyo of the Joseon dynasty.

The purpose of this study is to compare the books exchange between china and Joseon dynasty. Books, ancient and modern are an essential part to publish, propagate, administer the books which is a matter of grave concern among nations. Also they are the most important information and the symbol of the government power. As a result the rulers had brought many necessary books from China and it is a national policy to govern in Joson dynasty. This study will discuss the introduction of chinese books from the Annals of the Joson Dynasty, especially from the first king of the Joson Dynasty, Yi Seong-gye to the ninth king. At that times, Joson Dynasty had attempted to reign various policies. So many books related with the absolute authority of China. In accordance with the book classification method in ancient china, they are have been categorized. Furthermore, it should have been a important clue to check the influence by being brought many books from China.

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.

This study investigates when and why the light pink Dan-ryoung appeared as part of the official uniform of the Joseon Dynasty and which official uniform used the light pink color. The Annals of the Joseon Dynasty, books written by scholars, and related laws were used as research materials. The following results were obtained by analyzing the arguments of kings and officials on light pink uniforms and laws related to official uniforms. 1. Red was the color of the king as well as the color of Dang-sang-gwan's Gong-bok (one of the official uniforms). 2. The colors such as To-hong, Dam-hong, Do-hong, Bun-hong, Cheon-hong that appeared in Sang-bok (among official uniforms) were relatively lighter than red. 3. To-hong started to be used in Sang-bok at the time of King Se-jong and was used at the time of King Seong-jong in Sang-bok because it was the preferred color. 4. In the Joseon Dynasty, safflower (the basis of red color dye) was cultivated extensively; in addition, people liked red dyeing because it was relatively easy apply; subsequently, a ban on red dyeing was continually issued. 5. Kings Se-jong and Jung-jong ordered officials to use Do-hong and Bun-hong to distinguish the red color of the king. After Im-jin-oe-ran, Cheon-hong was officially designated the color of Sang-bok. 6. The reasons why Dam-hong was used in official uniforms were twofold: the preference for red-like colors and the influence of the Confucian hierarchy to distinguish the king.

The sleeve is closely connected with activity in terms of costume. As a kind of overcoat, Dap-ho of the Joseon Dynasty is short-sleeved or sleeveless. Dap-ho, with simple sleeves is convenient for layering and taking off and since it is easily adjustable using a gusset, a slit, or coat string, and this can be applied to layered look-related designs. This study aims to suggest a design item, which sustains the existence of traditional costumes and facilitates diverse layered looks and co-ordination, using the formative elements of Dap-ho. For this study, theoretical backgrounds and relics of Dap-ho of the Joseon Dynasty were analyzed, based on the previous studies, ancient literature, "The Annals of the Joseon Dynasty", and relics preserved in museums. The analysis targeted nine relics that show the birth and death years and the constructive changes in shapes, colors, materials of Dap-ho. Formative elements of Dap-ho were applied to the designing and the manufacturing of clothes for middle-aged women in their fifties and the research conclusions are as follows. First, from a morphological perspective, the silhouette, gusset, slit, and the indirectly attached coat string of Dap-ho are good to be used as various design items for covering the body shapes of middle-aged women, and the short-sleeved or sleeveless type is convenient to be layered. Second, when it comes to the material, it is possible to emphasize a traditional image and practicality at the same time by mixing and matching the Hanbok cloth and cotton. Third, in relation to the colors, the coexistence-based color arrangement method considering the theory of Yin and Yang can be applied to modern clothes and this makes it possible to express a traditional image in a harmonious way.

A paulownia wood has been widely used with various advantages as its low weight, permeability, convenient workability and aesthetic patterns for a long time. However, the related empirical researches and simultaneous evaluations of functionality are insufficient compared with acid-free archival boxes for now. In this study, the indoor and outdoor temperature and relative humidity control and heat release rate were evaluated under the controlled and uncontrolled circumstance in 2018. The paulownia wood storage box showed superior control effect of relative humidity than the acid-free archival box in constantly uncontrolled environment. Also, the possibility of the flame diffusion from the surface of the materials was higher for the paulownia materials, and the acid-free archival box showed more dangerous patterns in the early stages of the fire.

We investigated the occurrence of red tide, harmful algal blooms(HABs), at the end of 14th century until the beginning of 19th century recorded in the Annals of the Joseon Dynasty, which are the authentic and encyclopedic annual records of the Joseon Dynasty of Korea. In total, 81 cases of HABs are recorded in the annals for which authors draw a table and maps. The number of HABs occurrence at each sea is as follows: 68 times at the South Sea; 50 times at the East Sea; and 23 times at the Yellow Sea. A region hit by red tide most frequently was Gyeongsang-do Province (over 80 times), which borders on both the South Sea and the East Sea. HABs written in the annals follow two distinctive occurrence patterns. The first pattern shows red tide started at Gangwon-do Province in March, spread north to Hamgyeongnam-do Province in April, and moved further north to Hamgyeongbuk-do Province in May and June. On the other hand, the second pattern shows red tide occurred in Gyeongsangnam-do Province in August and then expanded north to Gyeongsangbuk-do Province in September. HABs generally happened from March to September, culminating in August. Paralytic shellfish poisoning incidents involving human deaths were reported in Jinhae, Geoje and Tongyeong, occurring February to June. Fish mortality increased throughout Gyeongsang-do Province from July to September. HABs occurred on an extensive scale from 1394 to 1451 and again from 1654 to 1706. HABs also occurred on a lesser scale from 1493 to 1534 and again from 1588 to 1609. In general, vast HABs occurred in odd years (1399, 1403, 1413 and 1681).
