Seonreung is the tomb of Seong-jong (A.D. 1457~1494), the 9th king of Joseon Dynasty (1392-1910) and his second queen Jeonghyeon-wanghu (1462~1530). We obtained dendrochronological dates of Jeongjagak (ceremonial hall) of Seonreung. It was known first built in 1495 and reconstructed in October 1706, We obtained tree-ring dates of 20 wood elements (beams, pillars, truss posts, cant strips, roof boards and roof loaders). Their outermost rings were dated from 1630 to 1705. The dates of bark rings in four elements were A.D. 1705 with completed latewoods, indicating that these woods were cut some time between the autumn of 1705 and spring of 1706. The results confirmed the reconstruction date Jeongjagak of Seonreung in 1706, suggesting that there was not so long period for wood drying or storage, i.e., less than 6 months. The dates of outermost rings prior to 1705 in other elements indicated that some outer rings of these elements were removed during wood processing. Tree-ring dating proved that the present Jeongjagak of Seonreung had been well preserved for more than 300 years.

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.

The purpose of this research is to look into the tea-drinking pictures of the Joseon Dynasty in order to find the unique landscape traits of tea-drinking spaces of the era. A number of tea-drinking pictures were drawn during the Joseon Dynasty period and in most cases, the names of the painters are stated as well. These factors make tea-drinking pictures a seminal source that illustrates the landscape traits of the last Dynasty of Korea. For those pictures contain the main components of landscape such as the tastes of 'Yangban'(noblemen), natural characters, and space traits. Since tea was first introduced in Korea during the Three Kingdom Period, tea-drinking culture has a long history in the country. There have been various studies about tea and many study results have been presented. Few research, however, have looked into tea culture from the point of landscape. Under the premise that tea-drinking pictures of Joseon Dynasty can be a cultural code that explains Korean tea-drinking culture, this thesis looked into those pictures from various angles and analyzed them in order to elucidate the attributes of scenery components of tea-drinking spaces that Koreans have forged and developed, and following results could be found. The Landscape components illustrated in tea-drinking pictures of the Joseon Dynasty can be divided into the element of architecture, the element of water, stone and plants. First, for the element of architecture, it was found that tea-drinking took place in anywhere in Korea without specific tea-drinking buildings or gardens unlike the case of Japan. This has to do with traits of Koreans who were not bound by formality and truly loved nature. Second, for the element of water, water contributed to making harmonious landscape. Third, for the element of stone, it was clear that stone had a practical role in providing comfortable place for lying and enjoying tea-drinking and scenery. Fourth, plants made elegant figure in the landscape and were planted in accordance with their inner meaning. Tea-drinking pictures of the Joseon Dynasty elucidates that when it comes to tea-drinking, Koreans were not obsessed with a formality of tea-drinking, or a set of tea ceremony, which is profoundly different with Japanese, and Koreans did not put a limit on a place for tea-drinking because for Koreans any place they sat could be a great place for tea-drinking.

Gyupyo (圭表, Gnomon) consists of Gyu (圭, Measuring Scale) and Pyo (表, Column), and was one of the traditional astronomical instruments in East Asia. Daegyupyo (Large Gnomon) was manufactured in the Joseon dynasty around 1434 ~ 1435. To increase the measurement accuracy, it was equipped with a Hoengyang (橫梁, Cross-bar) and used a Youngbu (影符, Shadow-Definer) which was invented during the Yuan dynasty (1271 ~ 1368). The cross-bar was installed on the top of the column and this structure was called Eol. In addition, three plumbs hanging from the cross-bar was employed to vertically built Eol on the measuring scale. This method was also used to not only check the vertical of Eol but also diagnose the horizontal of the cross-bar. Throughout this study, we found that a cross-bar in a gnomon has played three important roles; measurement of the shadow length made by the central part of the Sun, increase of the measurement precision using the shadow-definer, and diagnosis of the vertical of Eol and the horizontal of the cross-bar itself using the three plumbs. Hence, it can be evaluated that the employment of a cross-bar and a shadow-definer in a gnomon was a high technology in the contemporary times. In conclusion, we think that this study is helpful for understanding the Large Gnomon of the Joseon dynasty.

This Research is focused on ancient battle formation basing on the layout drawing of Yijinchongbang (manuals of learning military formations) in a strategy book in the late Joseon dynasty. The research topic is the principles of organic composition of battle formation and battlefield operating system by reforming the basic model of ancient battle formation. The research method is comparative analysis by reforming the battlefield operating system of types of disposition such as Obangjindisposition(Bangnjin; battle formation, Jikjin; direct battle formation, Gokjin; bend battle formation, Wonjin; round battle formation, and Yejin; keen battle formation), and Hyunmoojindo; turtle battle formation, Paljindo; all-rounder battle formation, Yookhwajindo; six flowers battle formation, Gugunjindo; nine forms battle formation. From the study results, Standoff Bombing of the battle formation in the late Joseon Dynasty basically started out from magic battle formation, but was then transformed into square, rectangle, pentagon, and circle. Also, the battle array composition used a 5-linear structure and was composed of 5 systems of circulation such as rectangle, square, diagonal, curve, and circle. The research findings elucidate the battlefield of the Joseon dynasty by establishing the real battle formation, and thus have military and academic value in suggesting possible tactics that can be used by modern training of military.

This study aims to figure out the weather and climate environment of Seoul area in S. Korea during 1623~1800, which has not been studied so far, by using daily records of weather conditions and meteorological phenomena in the Daily Records of Royal Secretariat of Joseon Dynasty(承政院日記) together with records of abnormal weather conditions and natural disasters in the Annals of the Joseon Dynasty(朝鮮王朝實錄). During 1500~1760 as a period of the Little Ice Age it was generally cold and dry, particularly cool summers of Seoul area. Changes in weather conditions and meteorological phenomena and climate changes appeared prominently at around 1650, 1710, 1770. The annual numbers of rain days and of snow days began to change largely in the 1640s. The rain(and snow) days reduced significantly in the 1710s~1650s, but increased sharply in the 1710s and later. The rain days in summer rapidly increased after the late 1710s, while the snow days greatly reduced after the mid 1770s. The cloudy days around the 1710s greatly reduced in summer, while slightly increased in winter. The hail days increased significantly in the late 1720s and lasted until the 1760s. The fog days began to reduce after 1770 to the fewer days than the climatic normals of 1981~2010. These times are overall consistent with findings of historical climatological cross-checking data and geophysical biological proxy data, accompanied by a trend of relatively enhanced colder and drier of Seoul area.

The Hoeamsa Temple of Yangju City was established at least during the late Korea Dynasty. This temple was rebuilt several times with the support of the royal family from the late Korea Dynasty to the early Joseon Dynasty. It was continually rebuilt in association with JiGong monk, HyeKeun monk, and MuHak monk. Hoeamsa temple was leading the Buddhist culture as a Buddhist center of the Joseon Dynasty . It was destroyed in the late Joseon Period. This site has been excavated several times since 1997. Various roofing tiles were unearthed. Of these tiles the edge of eaves are the artifacts showing the best features of this era. In this temple site has been excavated a variety of Sanskrit roof tiles. These tiles were made using superior technique. On the roof tiles are engraved Sanskrit mantras with a variety of 1 to 9 words. The jeongbeopkkye mantra(oṃ raṃ) and six-word mantra(oṃ ma ṇi pa dme hūṃ) were discovered the most. These mantras were believe to expel several evils from the Buddhist temple. It must have been that the six-word mantra culture became prevalent and provided a turning point in the history of Korean Buddhism. We can clearly know when some of the Sanskrit roof tiles were first manufactured. These roof tiles are the absolute standard of the other Sanskrit roof tiles excavated from different Buddhist temples. The master craftsmen must have been very skilled, understood the mantra very well, and had deep faith in the Sanskrit mantra. Hoeamsa Temple is a milestone in studying the Sanskrit roof tiles. More studies on various aspects are expected to be followed.

This study is for the collection and analysis of historical records on forest culture. It aims to satisfy the people's needs for forest culture by collecting and analyzing forest-related materials described in the law codes of the Joseon Dynasty to grasp the general matters of the forest culture at that time. From the provisions related to forests in the law codes of the Joseon Dynasty (Gyeongguk Daejeon, Sokdaejeon, Daejeon Tongpyeon and Daejeonhoetong), it was possible to gain insights into the process of changes in forest administration and policies, and changes in forest landscape, etc. Analysis of the Gyeongguk Daejeon revealed the following facts; at that time, special tree species or trees produced only in specific regions were managed separately; and there was a lot of attention paid to manage the landscape of specific areas; for reserved forest management regulations, beyond the level of logging bans, attention was paid not only to planting and cultivation, but also to landscape creation. In addition, it was found that private ownership of forests was generally forbidden, however, the ownership of a certain range of forests around the tombs was recognized for funeral rites.

Korea has a long history in astronomy, which is proved by many observational records written in Korean chronicles. There are 43 sunspot records in Goryeo dynasty (高麗 918-1392) and 13 records in Joseon dynasty (朝鮮 1392-1910). According to analysis of Korean historical records, it is known that sunspot records in Goryeo dynasty show well in match with the well-known solar activity of 11.3 years. It means that Korean historical sunspot records show real solar phenomena. Korean sunspot records also show that solar activity decrease in Joseon dynasty compared with the previous ~500 years. In order to know the change of solar activity in detail, we examine Korean historical atmospheric records which can indicate climate change. We first analyze historical frost records. Korean chronicles have around 600 frost records during the last millennium. We find that the climate change shows sign of cooling down when check the variation of epoch that the first and last frost events in each year are written. This result is well in accord with that of historical sunspot records. Therefore, we claim that solar activity decrease during the last thousand years.
