This study investigated mechanical property changes by measuring compression factors, resilience, and compressive strength according to packaging pattern and filling rate to identify the applicability of cultural heritage packaging using thermoplastic polyurethane elastomers (TPU). Research results indicate that the cross-shaped 3D pattern showed the best resilience when the internal filling rate was 20%, while the octet pattern was the best when the filling rate was either 40 and 60%. The octet pattern had the best mechanical properties and stability with resistance capacities of 20.79 kgf/cm², 40.40 kgf/cm², and 82.23 kgf/cm² at 38%, 39%, and 40% recovery speeds, respectively, depending on the internal filling rate (20, 40, 60%). Based on these results, basic data on the applicability, stability, and reliability of 3D cultural heritage packaging materials using TPU materials were obtained.

This study explores the effects of X-ray irradiation for biological control and high-temperature degradation on dye stability in dyed textiles with Gardenia. To evaluate this study, optimal extraction solvents for these textiles were identified by comparing them with a crocin standard solution. Extraction using pyridine closely matched crocin. The study then assessed the stability of X-ray irradiation and high-temperature degradation on these textiles. Transparent yellow dyes were observed in all samples. Color differences were found to increase at higher irradiation doses and longer degradation periods. While UV spectroscopy spectra showed broadening and lowering trends with higher irradiation doses and longer degradation periods, suggesting a reduction in colorant transition, mass spectrometry revealed minimal chemical changes. In conclusion, both X-ray irradiation and high-temperature degradation induced spectral changes without complete dye decomposition. Major colorants were consistently detected.

To investigate bioactive materials for development of natural conservative agent on organic cultural heritage, methanol extracts from 17 medicinal plants were screened for antifungal and insecticidal activity against 6 wood rot fungi and adult of Lasioderma serricorne. Antifungal activity of extracts was tested by using paper disc soaking method against wood-rot fungi. Among these extracts, the most significant antimicrobial activity was observed from the extract of Coptis japonica at 5 mg/disc against all wood rot fungi tested. The insecticidal activity of extracts was examined by topical application against L. serricorne adults. The extracts from Asarum sieboldii gave 83.3 % mortality at $25{\mu}g/adult$ for 24hr. From these result, the methanol extract from C. japonica and A. sieboldii described could be useful for conservation of organic cultural heritage against biological deterioration by wood rot fungi and L. serricorne.

Visual analytic for intangible cultural heritage has recently developed in China. Using advanced interactive visualization tools experts can observe data distribution trends and explore the implicit relationships among data within a short time. It can enhance human cognitive and analytical abilities and improve the scientific preservation of intangible cultural heritage. To support this research topic, we have reviewed recent visualization works on intangible cultural heritage in China. We divide these works into three types: text visualization, multi-dimensional visualization, and geographical visualization. Each type is illustrated by several representative works. New development trends in this area are also discussed.

After the 'Guidelines for the preservation of digital heritage' were published by UNESCO, interests in the fabrication of digital cultural heritage have been increasing throughout the world. The present study was intended to fabricate digital cultural heritages for existing cultural properties using the reverse engineering technology and obtain two-dimensional drawings. Jinju Castle Gongbukmun, which is a cultural property, was selected as a study subject and 3D modeling of Jinju Castle Gongbukmun was conducted by implementing 3D scanning and processing the point cloud data. Using the Gongbukmun 3D model (3D-Gongbukmun) made as such, requirements as a digital heritage were reviewed and 2D drawings of Gongbukmun such as front views, ground plans, and side views could be prepared.

This paper aims to improve the quality of cultural experience by providing a three - dimensional guide service that enables users to experience themselves without additional guides and cultural commentators using the latest mobile IT technology to enhance understanding of cultural heritage. In this paper, we propose a method of constructing cultural contents based on location information such as user / cultural heritage using markerless tracking based augmented reality and GPS. We use marker detection technology and markerless tracking technology to recognize smart augmented reality object accurately and accurate recognition according to the state of cultural heritage, and also use Android's Google map to locate the user. The purpose of this paper is to produce content for introducing cultural heritage using GPS and augmented reality based on Android. It can be used in combination with various objects beyond the limitation of existing augmented reality contents.

본 논문에서는 수중 문화재를 주제로 오감 인터랙션을 활용한 디지로그 전시 기법을 연구한다. 영상을 활용한 디지털미디어가 중심인 기존의 전시 기법에 시각, 청각, 촉각과 같은 다양한 감각기관을 활용한 인터랙션을 추가함으로써 관람객에게 새로운 경험을 제공하고자 한다. 프로젝션 매핑, 증강현실과 같은 디지털 기술과 난파선과 자갈, 실물 크기의 모형 유물과 같은 아날로그를 결합하여 관람객에게 실재감을 주어 효과적인 몰입감(flow)을 유도하고자 한다.

Examples for application of cultural properties using Infrared Reflectography System as method of investigation on mural paintings and letters are given. This work is carried out according to asking of examination on inner layer paintings and letters in order to conserve the mural paintings discovered in the course of repairing ancient architectures. It is difficult to find the inner layer paintings and fine decorative line, but we can be observed by using Infrared Reflectography System and thus these results can be used as original rebuilding and drawings of mural paintings. Also building-repairing year, building participant though the investigation of letters written on the roof wood can be known.

In this study, a scientific survey on the material of the mother-of-pearl floor mirror was conducted and conservation treatment processes were introduced. The survey results showed that the mother-of-pearl floor mirror in Daejojeon Hall of Changdeokgung is made of Dalbergia spp., and repair work seems to be done later with shorea spp. FT-IR analysis results showed that the varnishing is similar to the spectrum of lacquer. The metal wheels and metal line decorations set with mother-of-pearl were found to be made of brass based on XRF analysis, and the ingredient ratio showed that these were made in modern times. Foreign materials were stuck on the surface of the mother-of-pearl floor mirror before conservation treatment, which was in a structurally unstable condition owing to some missing submaterials. Conservation treatment was conducted on the damaged area to restore the mirror to its original appearance by using the same species of wood determined from the data obtained through the scientific survey.

Recently, at home and abroad cultural content industry has developed as the growing importance of history. Among them, the reconstruction contents area which combined with IT technology is attracting attention. Specially, using augmented reality technology, 3D visualization researches which restore contents of architectural heritage, cultural heritage sites, and artifacts have been performed in cultural content area. The existing cultural site restore contents are mostly made based on the images taken from indoor. In this paper, efficiently visualize the restore contents in indoor, but outdoors is limited. This theses presents the cultural heritage sites 3D model visualization system using augmented reality in outdoor. Proposed system augments 3D model to cultural heritage site in outdoor by using Smart Phone.
