This study investigates the crystallinity distribution of ancient silk. Owing to the inherent multi-hierarchical structure of silk protein and the complicated structural changes that occur due to various burial environments, it is challenging but worthwhile to study ancient silk ageing behavior, which is based on the fact that ageing begins with a single fiber and then spreads to a whole fabric. Crystallinity was one of the most effective indicators found to reveal the ageing status of silk. Therefore, a synchrotron radiation-based X-ray diffraction(SR-XRD) method was employed to study the crystallinity distribution of single fibers of ancient silk unearthed from seven archaeological sites in China from historical periods including the warring states, Han dynasty, Song dynasty, and Ming dynasty. In comparison, the conventional X-ray diffraction method, which uses large amounts of samples, was also performed to determine the integral crystallinity of ancient silk. Thermal stability experiments by thermogravimetry(TG) as well as morphology observations by scanning electron microscopy(SEM) and optical microscopy(OM) all confirmed the deterioration of ancient silk. Moreover, the ageing mechanism of ancient silk was proposed with the assistance of an artificial ageing study. The results confirmed the effectiveness of SR-XRD as an ageing indicator, revealing the crystallinity distribution. This research could provide motivation to determine the deterioration status of ancient silk, and would also aid in explaining the fragility of ancient silk due to ageing.

The following paper deals with Persian costume of Achaemanid period in Persia. The study about Persian costume is very important for the research of European and Asian costume. However, its theme is insufficiently examined until now, so we were not able to recognize the Persian costume culture properly. For the reason mentioned above, this study is necessary for understanding the Persian costume culture at that time correctly. The research was undertaken with the information on historical archaeological art sites, analyzing the dressing carved in the reliefs of king's Audiencescene in Apadanastairs in Persepolis. The results driven from the study are as the following: There are two styles in the reliefs of Audiencescene in Apadanastairs. One is long robe with pleats, which is called Persiandress. The other is tunic and trousers. Persiandress, long robe with pleats which was the typical dress in Persia at that time was originally the dress of Elamites, who occupied a very advanced civilization in this region. This robe was a borrowing by the Persians from their Elamite neighbours as formal dress. There is the Persian dress worn by king, prince, guardsmen, servants in the reliefs of Audiencescene in Apadanastairs. It is inferred from this that the dress was popularly worn in Persian court. Tunic and trousers, the typical clothing of ridding race, is worn by Median who is one of the relatives of Persian. The tunic has narrow sleeves and is reaching the knees. The trousers are ending at the ankle. Beyond the clothing, various headgear are also examined according to the social status and nationality. These are being precious materials for study on the persian costume among the relations with other surrounding countries.

OSL dating for three hearths having the sequence of use and discard in No. 29 and 29-1 dwelling sites at Sogol cultural site was carried out. Resulting from the deconvolution of natural CW-OSL decay curve and thermal zeroing test, it was turned out that OSL signal was entirely composed of the heat- and light-sensitive fast component with high photoionization cross-section and all quartz OSL signals were thermally bleached under $300^{\circ}C$ which is the minimum temperature related to heating and cooking in Bronze age. After dose recovery test and plateau test, paleodose of each hearth sample was evaluated by using SAR method, and OSL age was determined from the ratio of paleodose to annual dose rate. For the purpose of the precision improvement of OSL age, Bayesian statistics was applied to each hearth's age and the archaeological sequence information. Finally, it could be concluded to the accurate use period of each hearth from the resultant OSL ages.

The purpose of this study was to observe school education system, higher education, and fashion education in Germany to find a good model for an desirable future education to lead a creative students in Korea, thereby reshaping curriculum. We also analysed the curriculum of the fashion design offered in Hochschule Pforzheim and Berlin University of Art. We used secondary data collection by literature reviews of articles and web sites on the internet. Results of this study are as follows: German school and education system oriented with differentiation even though there are variety of them. Students can select their education system, considering work field and their own life & humanities. Various fashion education institutions were found to have their own education concept to enhance creativity with different system. Our results of analysis of the fashion design program of Hochschule Pforzheim and Berlin University of Art show their creativity education in their curriculums with module basis. Two universities have a differentiate education direction for the same aim to do creative design study and research. We realized that students learn and get the knowledge and apply to the field with a long term internship, communication skill and presentation development courses. Project based modules enable students to be creative, and active human. Strong design basis, and humanities disciplines will support people to creative design works. These two universities offer a good model of program to build up self education drive, academic and practical ways of training, and project based, internship, etc.

The 5th century kiln that produced pottery coffins was found for the first time in Korea, located in the Oryang-dong remains in the city of Naju. This kiln, located in the central area of the Yeongsan River, provides important data for research on mortuary practices in prehistoric society, including the structure of production and patterns of distribution and consumption. For this study, the remains of five ancient tombs and pottery coffins excavated from the 4th century Mandong archaeological site were chosen to determine the area of consumption of pottery coffins produced at the Oryang-dong kiln. The samples from each area of remains were analyzed for minor elements using neutron activation analysis method, and from these results, the identities of the corresponding production areas were investigated using the multi-variant statistical analysis of discriminant analysis. The evidence strongly suggests that pottery coffins produced at the Oryang-dong kiln in Naju were used in ancient tombs of the Bannam mound in Naju, the Okyari mound in Yeongam, and the Banam mound in Hampyeong, reaching those sites through trade and distribution. The findings also suggest that pottery coffins from the Mandong archeological site in Gochang and the Inpyeong mound in Muan were not produced at the Oryang-dong kiln in Naju, but rather were brought from pottery kilns in different production areas, through trade and distribution.

For several years, we have conducted a series of studies on the patterns of ancient parasitism prevailing in the soil of rural and urban areas of past Kingdom of Korea. Actually, during our survey of paleoparasitology in archaeological sites of Korean peninsula, numerous ancient parasite eggs were discovered in the samples from the city districts of Hansung (Joseon) and Buyeo (Baikje), the palace moat at Gyeongju (Silla), shell-midden site at Bonghwang-dong (Silla to Joseon), and the reservoir found in Hwawangsansung fortress (Silla). By the paleoparasitological studies, with respect to parasitism in the high-density populations of ancient towns and cities, we have managed to catch glimpses of the patterns prevalent therein: a serious parasitic contamination of the soil in ancient urban areas, but not in rural areas of the past. Our historical research also proposed the plausible mechanism of parasite infection very serious indeed among urban populations in Korean history. Although city dwelling doubtless has accrued significant benefits for people and populations with agriculture, it can be equally supposed that living in such highly populated areas might have facilitated the spread of parasite infection.

Over the last three decades, advances in AMS (Accelerator Mass Spectrometry) and Noble Gas Mass Spectrometer make various application of terrestrial cosmogenic nuclides (CNs) to wide range of earth surface sciences possible. Dating techniques can be divided into three sub-approaches: simple surface exposure dating, depth-profile dating, and burial dating, depending on the condition of targeted surfaces. In terms of Korean landscape view, CNs dating can be applied to fluvial and marine terrace, alluvial fan, tectonic landform (fault scarp and faulted surfaces), debris landforms such as rock fall, talus, block field and stream, lacustrine and marine wave-cut platform, cave deposits, Pliocene basin fill and archaeological sites. In addition, in terms of lithology, the previous limit to quartz-rich rocks such as granite and gneiss can be expanded to volcanic and carbonate rocks with the help of recent advances in CNs analysis in those rocks.

We analyzed the provenance and petrographic characteristics for the rock properties from stone-lined tomb and stone chamber tomb at the Dorim-ri site of the Baekje Kingdom, located in Cheonan. The two tombs consist of 10 kinds of rocks including gneiss, diorite, and andesite. The major rock type is gneiss (54.3%), which composes the main chamber walls of the tombs. Diorite (11.3%) and andesite (10.6%) also make up a large percentage of the rocks, tending to be used to fill the space between the main chamber walls. Thus, the stones appear to have been used according to their shape and the disposition of the site, respectively. Investigation of their provenance, confirmed their source area to be near the Ipjang Reservoir, about 1 km away from the site, and their procurement was probably conducted via a waterway. This result might serve as basic data regarding the material procurement system of ancient tomb culture and for preservation measures for archaeological sites.

Gongsanseong Fortress was registered of a World Heritage Site in 2015 as a representative cultural heritage from the Woongjin Baekje period, and it has been used throughout the entire period from Baekje Kingdom to the Joseon Dynasty. Within Gongsanseong Fortress, the area around Ssangsujeong is presumed the site of royal palace of the Woongjin Baekje. Also, the excavated culture layers of the Baekje Kingdom, the Unified Silla period, and the Joseon Dynasty were confirmed. In this study, paleotopography was modeled by digitally converting the elevation data obtained through surveying the excavation process, and the use of the topography in the Ssangsujeong area was considered by examining the variations in the topography according to the periods. As a result, the topography of the slope around the peak changed by periods, and the topography did not change on the flat land. The topography between the Baekje Kingdom and the Unified Silla period appeared to be almost identical, and it seems that the space of the Baekje period was maintained as it is. Also, during the Joseon Dynasty, it is confirmed that flat surfaces in the previous period were used. However, sediments on the slopes flowed down, reducing the area of the flatland, and architectural techniques that could utilize the natural topography of the changed slope were applied to interpret it as having a different topography from the previous period. In order to model and interpret the paleotopography, excavation data, geological and topographic analysis, and digital data must be secured. It is expected that location conditions and ancient human life can be identified if the analysis technique in the study is applied to other archaeological sites in the future.

According to the "Special Act on the Restoration and Maintenance of the Core Relics of the Shilla Kingdom" enacted in 2019, the Shilla Kingdom refers to the capital of Shilla and Unified Shilla period, and refers to Gyeongju, where the king lived, and the nearby area. Shilla Wanggyeong is a heritage registered on the UNESCO World Heritage List in 2000 under the name of Gyeongju Historic Site and belongs to Wolseong District, Hwangnyongsa District, and Daeneungwon District among the five districts registered as Gyeongju Historic Site. Unlike the Namsan and Sanseong districts, the Shilla Kingdom is a heritage consisting mostly of archaeological sites without physical substance. Gyeongju City sought to promote local tourism while providing more direct experiences to visitors by restoring the heritage that constitutes the Shilla Kingdom. Starting with the restoration of Woljeonggyo Bridge in 2005, the Shilla Wanggyeong restoration project began in earnest. Gyeongju City tried to restore the building site on the west side of Donggung Palace and Wolji after Woljeonggyo Bridge, but it was canceled due to opposition from the UNESCO World Heritage Committee. The World Heritage Committee opposed the restoration and recommended a heritage impact assessment for similar projects in the future. During the miscarriage impact assessment procedure, there is an OUV attribute analysis process of the heritage to be evaluated. This study intends to preemptively derive OUV attributes for the Silla Kingdom through literature and overseas case analysis. In the case of literature research, domestic and foreign research data related to the UNESCO World Heritage Convention and World Heritage Management were examined, and in overseas cases, the architectural works of Krakow Historical District, Stonehenge and Abbury Geoseok Ruins in England, and Le Corbusier were analyzed. Through this, the outstanding universal value attributes of the Silla Kingdom were derived. This study is expected to be used as a reference in the process of restoration projects of other heritage constituting the Shilla Kingdom or construction plans in nearby areas in the future and serve as an indicator to improve the management system of the Shilla Kingdom more efficiently from the perspective of world heritage.
