We checked the conditions and material properties after producing the lime finishing layers with a mortar mix of processed lime. In addition, we reproduced the lime finishing layers of the Koguryo Tomb Murals, colored the layers with a few different techniques and identified the characteristics for each painting technique. As a result of the experiment, we could infer the producing techniques as well as teaming the conditions and properties of the lime finishing layers of the Koguryo tomb murals, and examined the maintenance of the lime finishing layers. Of those samples produced under various conditions, the layers of slaked lime, which were obtained after being hydrated underground for a long time, showed quite a good condition. Thus the slaked lime mixes produced through particular hydration methods are judged to increase the maintenance of the lime finishing layers of the Koguryo Tomb Murals. Mostly, the paints of Koguryo Tomb Murals indicated that they have similar conditions with the samples produced with a secco method. In addition, Considering the compositional forms of the painting layers and the boundary layers which formed between the painting layers and the finishing layers, we can verify that, in some cases, the conditions of the painting layers of the Koguryo tomb murals are similar to those which were produced with a combination of fresco and secco.

Two lime-soil mixture barrier tombs were excavated from the tomb complex of the Woo Family of the Danyang Wu clan dating to the Joseon dynasty in Godeung-dong, Seongnam-si, Gyeonggi-do. Relevant records offer information for more precisely dating these tombs and identifying their occupants. Tomb No. 4, in which a married couple was interred, has a corbeled square ceiling and inscriptions and paintings on its outer walls. The conservation treatment and an infrared inspection revealed that they were intended to express mourning. Tomb No. 6 has a corbeled rectangular ceiling and a single individual interred within. As the basic structure of the tomb was partially damaged in the process of disassembling it while moving the burial site, it was planned to exhibit the tomb outdoors after the remains and relics are collected. However, as the conservation treatment revealed the presence of funeral fans and pitch, and since the remaining structure clearly demonstrates the features of lime-soil mixture barrier tombs from the Joseon dynasty, the plan was changed following a meeting of an advisory council that decided in favor of presenting the tomb indoors. According to the analysis, the pitch is assumed to be resin of a rather low purity due to the immixture of foreign substances. The two tombs are expected to serve as important materials for related research, such as changes by period in the forms of Joseon-era tombs.

Ancient tombs are typically comprised of confined rooms, which have different spatial characteristics than the external environment because they are covered by heavy layers of soil. In this study, we examined the thermal energy flow from the outside to inside of Songsan-ri tomb No. 6. External heat flows slowly to the inside because of heavy soil layer, and the presence of several rooms and entrances. For this reason, it takes about two months for the air temperature to travel from the outside to the inside of the tomb. Interestingly, the gradational inflow of thermal energy from outside the tomb leads to delicate horizontal and vertical variations in the wall temperature. These micro-environmental differences occur in the inner tomb every year, so we can expect them to cause condensation with regularity. In addition, we show that the previously installed forced circulation air conditioning system risks fatal damage to the mural wall painting. The results of this research suggest an optimal air conditioning system and optimized space planning to conserve Songsan-ri tomb No. 6 and its mural painting.

The lime-soil mixture on barrier (LSMB) tomb is a representative type of tomb from the Joseon Dynasty. It is an important reference for understanding the society and funeral culture of that time. The LSMB excavated at the Gungri site were classified with manufacturing type. The ultrasonic velocity and rebound hardness method were used to estimate the physical properties of the LSMB. The strength values on the tomb of layered wall were different depend on measuring method. The compressive strengths of the tomb with layered wall, which is calculated by ultrasonic velocity and rebound hardness ranged from 4.0 to 355 (mean 43.6) $kgf/cm^2$ and 18.8 to 538 (mean 245.2) $kgf/cm^2$ ranges. The damage to the tomb with integrated wall during excavation and removal of the corpse could be a reason for the difference in results obtained using ultrasonic velocity method. Compressive strengths of tombs with integrated wall, which is calculated by ultrasonic velocity and rebound hardness ranged from 5.7 to 793 (mean 281.6) $kgf/cm^2$ and 4.5 to 550.5 (mean 172.4) $kgf/cm^2$ values. Physical properties on the tombs of integrated wall had different in compressive strength value but showed similar tendency. Thus, evaluation of the physical properties has shown that measuring ultrasonic velocity and rebound hardness methods are more effective in the LSMB with integrated walls. Further, the strength values obtained through the rebound hardness method are more constant than those obtained through the ultrasonic method due to the small detection area required by the former.

This study revealed the material composition and characteristics of 19 glass fragments excavated from stone chamber No. 1 of Jeongchon Tomb in Naju through chemical composition analyses and observations. These characteristics were compared with the characteristics of the glass fragments excavated from No. 3 tomb of Bogam-ri in Naju. The purpose of this study was to identify the characteristics of the ancient glass of the Mahan-Baekje period. The glass fragments excavated from the Jeongchon Tombs can be classified into purplish blue, light-purplish blue, greenish blue, green, and mixture of purple blue and purple, based on their color. These beads were made using a drawn and casting technique. In addition, blue glass fragments were primarily excavated form No. 3 tomb of Bogam-ri. However, red glass fragments were not excavated from either of the tombs. According to chemical composition analyses, soda glass group and potash glass group were common in both the tombs. Additionally, alkali mixed glass group and lead barium glass group were excavated from Jeongchon Tombs and No. 3 tomb of Bogam-ri, respectively. The glass fragments excavated from No. 3 tomb of Bogam-ri have more color variations than those excavated from Jeongchon Tombs.

In this study, the raw material and tempers of bricks used in three brick tombs built in Gongju, during the Ungjin period of Baekje were investigated. The royal tomb of King Muryeong, the 6th tomb in the royal tombs, and Kyochonri brick tomb remained in Gongju and the bricks of each site had different shape and physical properties despite their similarity in raw materials. As the results of the mineralogical and microstructural analysis, the bricks of the royal tombs were made of refined raw materials, and were infrequently added crushed bricks(grogs) as a tempering material. On the other hand, thick and elongated pores of bricks from the Kyochonri brick tomb were frequently found, and the remains of plant carbonization are observed in their microstructures. Since the pores are mainly distributed in a thickness of 0.3 to 1 mm, it is estimated that bricks were produced by adding a certain size of the plant to refined soil, and grogs also were added as a tempering material. In particular, it was found that adding plants and grogs in raw materials of bricks caused thick pores or cracks in the internal structure. Since the bricks of the Kyochonri brick tomb have internal cracks and low firing temperature, the ultrasonic velocity of the bricks was lower than that of the royal tomb bricks. It means that the mechanical strength of these bricks were relatively low. Accordingly, it is estimated that the tempering materials, firing temperature, and internal structures of bricks can affect durability of the brick, and it can be thought as a difference in the manufacturing technology of brick making.

This study is to understand Chang-ui construction of the middle Chosun Dynasty through the reconstruction of the blue Chang-ui which was excavated from General Parks tomb. The followings are the results of this study. There are 4 styles in excavated Chang-ui of middle Chosun Dynasty: Two styles seem to belong to the early 17th Century and the other, the late 17th century. The former is classified into 2 styles by the gender of the wearer, the latter is also classified into 2 styles by etiquette of clothing. We can assume that Chang-ui excavated from General Parks tomb was the womans clothing in early 17th century. This Chang-ui(II) differs from other Chang-ui(I) at two points. One is the construction of the trapezoid and triangle gussets on the side seam of clothing. The other is the construction of the narrow width of clothing(23cm). We have found that these two gussets could improve the active aspect of clothing and save materials. It is identified that the green tone was faded from the blue color of Chang-ui according to the calculation of the L*a*b.

Yungneung is the royal tomb of King Jangjo (the Crown Prince Sado, 1735~1762) and his wife, Hyegyeonggung-the Lady Hong (1735~1815). King Jangjo was the second son of the 21st King Yeongjo of the Joseon Dynasty. The tomb of King Jangjo was originally established at Yangju near Seoul in 1762 and moved to Whaseong near Suwon in 1789. We examined tree-ring (dendrochronological) dates of Jeongjagak, the ceremonial hall and Bigak, the tombstone house of Yungneung. We obtained tree-ring dates of 54 wood elements. The dates of bark rings were A.D. 1785, 1786, and 1787 with completed latewoods. These tree-ring dates were well matched with the historically recorded date of two buildings, A.D. 1789 when two or three year-storage after cutting logs was considered. The results indicated that the present buildings of Yungneung was built when the royal tomb of King Jangjo was moved from Yangju to Suwon. A historical record about the construction of Yungneung, 'Hyeonyungwon-eugye' confirmed the majority of woods was moved from 'Manrichang', an official storage office in Seoul through Han river and Yellow Sea to Suwon.

The ondol is a uniquely Korean system of providing warmth to room. The ondol rooms never use daily life furniture because the ondol warms the floor surface where people sit. Finally, the ondol floor changed the traditional housings inner space. Before use ondol where daily life furnitures[sang(상) and Tap(탑)] are installed in the room. The origin of daily life furnitures are the ancient tomb mural of Koguryo Period. The daily life furniture can be classified as three large groups in the ancient tomb mural of Koguryo. First, a single seat[Jowa-sang(좌상)] of set up a screen[병풍]. The second, It make possible Many peoples take a seat with no decoration seat[Tap(탑)]. The third, uptodately table and chairs. A radical difference between sang(상) and Tap(탑) whether set up a screen[병풍]. The meaning of sang(상) and Tap(탑) in Koguryo ancient tomb provided Oksa-jo[옥사조] in Samkuk-sagi[삼국사기] with several valuable leads to help solve the sang(상)'s meaning. Furthermore, It will be start ponit of study on constructive shape of inner space in those days.

Waist lined Coat with Pleats excavated from Byun-su(1447-1524) Tomb in Yangpyeong were very similar in size to the costume of Haeina Temple which is the oldest YosunChollik up to now YosunChollik was popularly worn in the Yuan Dynasty of China(원) and it is presumed to be flown into Korea in that period. In China, the coat with a straight collar was called ByeonseonOh , and one with a round collar was called ByeonseonOhja in the Yuan Dynasty. The excavated relics of Haeinsa Temple are almost same as ByeonseonOh. In the Myoung Dynasty(명), the coat with a straight collar was called YoseonOhja, and one with a round collar was called Round collar YoseonOhja . The Waist lined Coat with Pleats excavated in the Byunsu Tomb is same as YoseonOhja Attendants who is low in position and doctors used to wear the coat, which was spread to diverse classes by degrees. Later, even emperors and high ranking officials used to wear it as military uniforms. It was made of silk and summer cloth. As mentioned above, 1 examined its history carefully through Chinese documents and photographic materials on relics. In addition, with the authentic records of Korea and the excavated relics of the Byun-su Tomb, 1 analyzed its components. However, the analysis was very restricted because the relics to be compared with were few.
