The sword with a ring pommel, which was excavated from the first stone chamber of the ancient tombs of Jeongchon Village in Naju, is a sword with a pentagon undecorated ring pommel consisting of a mother sword and two child swords. The sword with an undecorated ring pommel of Jeongchon comprises a ring pommel, a hilt, a knife, and a knife end decoration. This sword was coated with lacquer. The ring pommel is an iron frame covered with silver plate; however the silver tarnished into a light purple due to silver chloride corrosion, and iron corrosion originated from the inside is visible on the surface. Silver chloride corrosion is produced when silver objects are exposed to water, dissolved salts, and dissolved chloride ions when in a buried state. It changes objects into powder, making it difficult to preserve original shapes. The other silver artifacts found in the Jeongchon ancient tombs show similar signs of corrosion. The results of X-ray irradiation and a CT analysis showed that the sword had a ring at the end of the handle, a T-shaped hilt, and was probably connected to the handle end of a knife. If the shape of the mother sword can be inferred from the child swords, the mother sword had a ring pommel, decorations of the handle, covered with silver plate, and a gold ring and a silver line wound around the handle. It is assumed that the ring pommel was connected to the knife by welding because no holes were observed. The end decoration of the knife was made by using an iron plate formed into a shape, half covered by silk, and the other half decorated with silver plate and a gold ring. The sword with an undecorated ring pommel excavated from the ancient tombs of Jeongchon Village comprises the metals of gold, silver, and iron, and includes features of Baekje, Silla, and Gaya, which highlights the influence of surrounding historic sites and various cultures.

Ten historic sites (denoted as A- J in this study) of a tomb were found during the construction of the east-west expressway in District 2 of Hyangnam, Hwaseong, which is implemented by the Gyeonggi-do headquarters of the Korea Land & Housing Corporation. Thetombswere first detected at siteH, and further investigations revealed various tombs from the Three Kingdoms period; artifacts such as gilt-bronze shoes and caps were excavated from wooden coffins in the tombs. The pottery examined in this study was the only pottery artifact excavated from the site. Its raw clay was soft and loose, reddish brown, and had quartz and feldspar particles of < 1 mm, which appeared to have been added as reinforcing agents. The firing temperature of the pottery was estimated to be under 800-870 ℃ as the mica remains and tridimite, which is the phase transition mineral of quartz, was not produced; a slight endothermic peak was also detected because of the hydration of sericite at 800 ℃. The condition of the artifact was severely weakened because of various factors, such as soil pressure from the stratum formed over the site and repeated freezing and thawing. The artifact could not be collected alone, and thus, surrounding soil that had attached to the artifact was also collected; the artifact was transported to the laboratory and conservation treatment was conducted in a safe and systematic manner.

State Ownership of Excavated Cultural Heritage System was originated from the legislations concerning cultural objects during the Japanese colonial period (1910~1945) and was succeeded by the present Buried Cultural Properties Act enacted in 2011. Despite the importance of the system that completes the outcomes of excavations and determines the state-owned cultural properties, the foundation of national heritage, it has been limitedly regarded as administrative area and neglected by the academic scholars or policy researchers. Recently the traditional culture has drawn increasing domestic interest and awareness that the cultural heritage contributes to building cultural identity and vitalizing tourism has led to increasing the demand of a local government's role in management of the state-designated cultural heritage and even fighting for hegemony in securing the cultural objects between the central and local governments. Despite the continuing efforts for improving the selection process of cultural heritage and its management institution, establishment of an advanced objective system has been requested. This paper is intended to suggest the policy direction through demonstrating the problem and assignment caused in the process of implementing the Buried Cultural Properties Act and reviews the State Ownership of Excavated Cultural Heritage System from the legal point of view accordingly. First, I suggest improving the selection process of the state-owned cultural properties. Even though current law states that Administrator of Cultural Heritage Administration reviews the research reports and selects the possible candidates for the state-owned cultural properties almost all the cultural objects listed on the reports are practically selected. In this regard, two possible resolutions can be made; newly establishing a separate process for selecting the state-owned cultural properties after publishing the report or adding the selection process of the state-owned cultural properties during the heritage selection meeting. Either way should contribute to strengthening the impartiality and objectivity of the policy. My second suggestion is improving the operating system of the heritage selection meeting in which the cultural properties to be listed on the reports are determined. Given the present extensive assessment criteria, there is much room for certain experts' subjective opinions. Therefore, in order to enhance the fairness and credibility of the heritage selection meeting, specifying the assessment criteria and advance review of the expert list are necessary. Third, this paper suggests increasing the local government's role in management of the state-owned cultural heritage and diversifying the heritage management institution. Development of a local self-governing system has led to the increased demand for delegating the authority of the state-owned heritage management to the local governments. Along with this, the gradual improvements of public museum management raises the need for expanding the cultural benefits through increasing the local government's role in management of the state-owned heritage. Considering the fact that overall majority of the art collections housed at national or public museums is owned by the central government, developing a variety of heritage contents and vitalizing the heritage tourism are crucial. The true meaning and value of the state-owned cultural heritage hidden at the storage of a museum can be found when they are shared together with the public.

The Archaeological sites of so called Round Clay Rim Pottery (Jeomtodaetogi : 점토대토기) culture in Kangwon region have been rarely excavated in proper form. Since most cases belong to those of ground surface gatherings, it is difficult to certify the nature and the association with other artifacts. Therefore, researches on that culture have been limited to simply set the chronological order in the Bronze Age in realtion with the Plain Pottery culture. However, a comparative study trying to explain the Round Clay Rim Pottery culture in both Yeongseo(영서) and Yeongdong(영동) has become possible thanks to recent excavation results from the sites of Chilgeon-dong(칠전동) in Chunchon City(춘천시) and Songrim-ri(송림리) in Kangneung City(강릉시), for example. Certain difference can be observed in form and amount of artifacts in between Yeongseo and Yeongdong. Such difference can be seen as individual localization in different places diffused from a common source, rather than showing different stages of unilineal developmental process of one culture. The Round Clay Rim Pottery culture seems to have been coexisted with the Rim-Perforated Pottery(공렬토기) and Dolmen(지석묘) culture. According to the radiocarbondatings, the upper time limit of the Round Clay Rim Pottery culture goes back considerably beyond the alleged upper limit of either the late fourth century or the second century B.C.. However, both cultures absorbed into the Iron Culture during the same period.

Excavated iron objects are preserved in stable condition through processes of conservation treatment because they are found in the form of various corrosion products. However, the conservation treatment leads to re-corrosion over time and accordingly, iron objects can be severely damaged, and therefore fundamental measures need to be prepared to control it. In this study, the types and characteristics of corrosion products were scientifically analyzed according to the re-corrosion of iron artifacts. In addition, the stability of the corrosion products was evaluated by exposing the standard samples under the re-corrosion environment. Re-corrosion proceeded with weeping in reddish brown on the cracks of iron artifacts. Weeping was detected akagan$\acute{e}$ite had a low hydrogen ion concentration and high chloride ion. The selection of standard sample goethite, lepidocrocite, hematite, and magnetite, were evaluated corrosive by weeping. After the samples were immersed in HCl(pH 1), $H_2SO_4$(pH 1), $H_2O$(pH 6) solution, they had been maintained for 180 days in relative humidity of 20%, 50%, 80% to investiage the changes of chemical components. As a result of analysis, the changes of chemical components were not showed in goethite, lepidocrocite, and hematite. But magnetite was changed to lepidocrocite in solution including chloride ion($Cl^-$) and to goethite and lepidocrocite solution including sulfuric acid($SO{_4}^{2-}$). Results of the study, in the case of magnetite known as s stable corrosion compound, it was identified the corrosion of magnetite occurs by corrosive ions, which means weeping generated in the iron artifacts can corrode magnetite as well as base metal.

The primary focus of this thesis is to look at Scythai's historical, geographical and ethnologic background in order to understand Scythai's garment types and styles as described in Scythai-related documented records, previous studies and excavated artifacts. Based upon this, another objective lies in comparing and contrasting this information with ancient Korean garments to identify what kind of relationship exists between the two. The result from this study's objectives is summarized as follows. Firstly, ancient Korean and Scythai share similarities in art work, craftwork, accessories and the like, which allows us to make a guess at the relationship between ancient Korea and Scythai of that time. Secondly, Scythai garments are based on the tight and well-fitted Caftan Yugoje, which is tightly fit to the body, as well as including garments similar to the drapery Kiton and Tunic found in ancient Greek garments, from which can be seen that the garment of culture medium passing between the East and the West had nomadic horse-riders' ethnic characteristics and Eurasian characteristics. Thirdly, ancient Korean Scythai garments were found to have homogeneity in their garment culture in that northern nomadic cultural district's Hobok-Goseupje, i.e., open-front Caftan Jeogori and pants called Sangeuihago is its basic with a triangular cone hat shape (transformed hat) and boots, which is the basis for considering that ancient Korea exchanged culture with Scythai, who once lived as active northern nomads. However, it can also be seen that ancient Korea and Scythai garments differed in form depending on region, weather, culture, custom and the like. As such, Scythai and ancient Korea have an aesthetic bond because northern nomads and Scythai exchanged their cultural traits of the times. The evidence supports this idea as it seems that the characteristics of garments that can be considered to be Scythain in style are also commonly discovered in ancient Korean garments.

This study investigated the material properties of UV-curable Resin in order to identify stable materials for use in the restoration of glass cultural properties. Tested samples were based on acrylic UV-curable Resin (SECURE CP-7321®), to which urethane UV-curable Resin (FLGPCL04 Clear®) was added in 10% increments to produce eleven samples. The results showed that all eleven samples had similar properties in terms of refractive index, density, adhesive strength, and anti-yellowing. But the surface hardness and compressive strength were optimal and effective for maintaining the shape of artifacts after restoration treatment when the proportion of urethane resin was in the range of 10-20%. Based on these findings, the mixing sample [acrylic UV-curable Resin(9) : urethane UV-curable Resin(1)] was applied in the conservation treatment of a glass cultural propertie (Hwangbuk 519) excavated from the North Mound of Hwangnamdaechong, Tomb in Gyeongju.

Amber has been used as gemstones and artifacts from the period of the Three Kingdoms or earlier, which are discovered in the process of excavation now. It is, however, very difficult to discuss the importing route and circulation of amber because there are no informations available on the provenance. In this study, we acquired the IR spectra of ambers originating from 5 different locations. We also monitored the change of characteristic IR peaks by artificially aging the ambers under heat, light and heat with oxygen, respectively. As the aging proceeded, the intensity of C=O band and O-H band increased, however, the bands related with C=C bond decreased. There needed some modifications in the discerning scheme because some peak disappeared with aging; yet, it was still possible to discern different ambers largely. Therefore, it is expected that the scheme can be used practically by appraising its applicability to the real amber relics excavated.

Hwangrong Temple was the center of the Buddhist culture of Silla dynasty. It was built in the 14th year of King Jinheung in Silla dynasty, and completely burnt out when the Mongol Army invaded the Korean peninsula during the reign of King Gojong of Koryeo dynasty. 8-year excavation of the site from 1976 as part of the Gyeongju Tourism Comprehensive Plan revealed many things about the Hwangrongsaji. Recently, a book introduced 'Geumdongnanganpyeon' among relics found in the site, but omitted in the Excavation Report published at that time. Though 'Palgak Geumdongnanganpyeon' has numerical signs 六, 七(six, seven), there was no clear explanation of the signs. Thus, this paper examines it. We can guess, through the remaining iron fragment, that the side of Geumdongnanganpyeon is octagonal, and the width of the side S13 fragment belongs to is about 400mm. The overall form of the face is similar to the Geumdong Palgaktop stored in the Museum of Dongguk University, but, in detail, it is similar to the Zhuanlunzang Pavilion of Longxing Temple and the Sakyamuni Pagoda of Fogong Temple in China. And, numerical signs can be understand to designate the numbers of story and face. The reason why the number might indicate the number of story is that fragments which are presumed to be used for the same purpose contain different measurement values, and the basis of the concept of face can be found in efficiency of manufacturing and manufacturing techniques of artifacts of the time. The two aspects mentioned above cannot be confirmed because of not sufficient relics and related researches. But, the overall form may have been multi-story tower of at least two stories. If more studies in various fields are done in the future, it is expected that the original form will be recovered more accurately.

Pillows are tools that humans have used for a long time to sleep or lie down and rest. It is bedding, and the oldest literature dealing with it is Volume 29 of 'GoryeoDogyeong', which describes embroidered pillows. The oldest relic is the queen's pillow (National Treasure No. 164) excavated from the tomb of King Muryeong, and is in the Gongju National Museum. This study attempts to investigate and reproduce the materials used in traditional pillows Yukgol pillows and pine nut pillows designs are based on literature and artifacts from the Joseon period to modern times. Regarding the research method, after reviewing literature and the relics of traditional pillows, the process of reproducing the traditional Yukgol pillow and the pine nut pillow production method were explained step by step. This study found the plain attitudes in the lives of people who used materials that could be easily gained from their daily lives in rural communities oriented to rice farming never recklessly threw out any piece of cloth or cotton and use it for pillow stuffing or pillow ends. Also, the sophisticated sense of aesthetics that you can see from the pine nut pillows, whose ends were made of remnants from making clothing are exquisitely similar to what was shown in patchwork previously. The biggest meaning of restoring traditional pillows was looking into traditional culture, particularly the ordinary people's living culture. It was very difficult because the researcher had to find materials that were difficult to obtain in this age, the making process was complex, and it took much time; however, it is significant in that the restoration of traditional pillows allows for the succession of tradition.
