The Cultural Heritage Committee is an advisory committee established under the Cultural Heritage Administration with the aim of carrying out examination and deliberation on preservation, management and use of cultural properties. The Cultural Heritage Administration is responsible for Korean cultural properties. It was found to produce and execute policies on cultural properties, which involves in-depth investigation and consultation of experts in the fields of cultural properties. In here the Cultural Heritage Committee plays an important role in policy-making on Korean cultural properties. Governmental committees in Korea are largely divided into consultation committees and administrative commissions. Consultation committees are subdivided into consultation, deliberation and legislative committees. The Korean government established the Bureau of Cultural Properties in October 1961, and enacted provisions (as a presidential decree) on March 27, 1962, by the Cultural Properties Act, January 10, 1962. The Cultural Heritage Committee was opened as a deliberation committee which covers the entirety of cultural properties, including designation and cancellation of cultural properties, on which currently 120 members serve in 9 subcommittees. The committee member hold two years membership. This analysis contains a frame and scheme of the committee, function and statue of the current operation and study on role of a deliberation committee.

Lacquer has been used as a natural paint or adhesive in Korea since 2nd century B.C. It has been found to have been used as an adhesive as mentioned in old records and as seen in excavated relics, It was also mixed with flour, animal glue, or fish glue to produce lacquer adhesives. Qualitative analysis and evaluation of the applicability of lacquer and additives was performed in this study. The results of EGA analysis for lacquer additives confirmed that the pyrolysis temperature of lacquer, glucose glue, and animal glue. On the basis of this result, raw lacquer sample was checked that pyrolysis product that originated from urushiol side chain (R group). Components originating from glucose and amino acid were detected in glutinous rice paste and animal glue samples. In this study, the optimum pyrolysis temperature for each lacquer and additive mixture was determined from basic qualitative analysis data. By performing the qualitative analysis of each mixture, the applicability of this technique for analyzing real relics was evaluated.

This article cites examples of cultural heritages that urgently require protection measures, and the reinterpretation of beacons, fortresses, and extremities identified in the process of conducting a cultural heritage investigation of the DMZ and bordering areas. It is true that there are various difficulties involved in implementing thorough protection measures considering the reality of the two Koreas' division. Despite this, the "Ordinance for the Protection of Military Cultural Properties" and the "Act on the Protection and Investigation of Buried Cultural Heritage" have been enacted and are in effect. In particular, in the "Ordinance for the Protection of Military Cultural Properties," the value of protecting "military assets" is emphasized. The identification and investigation of cultural heritages in the DMZ and border areas must continue. Although field research is currently difficult, the primary investigation conducted by high-altitude terrain analysis and literature research is considered effective. Furthermore, there are parts that require correction and supplementation with future field investigations. Although some trial and error is expected during these various cultural heritage investigations, they need to continue.

This study intends to provide quantitative data about the extraction characteristics of major elements of earthenware by executing soaking test of cleaning agents. It aims at providing basic data for the stability assessment when applying the cleaning agents for conserving earthenware. The data will be extracted from the analysis of co-relationship between the physical characteristics and the ion extraction characteristics. XRD analysis displayed that AT-1, AT-2 and AT-3 which did not generate mullite were fired at lower than 1,000 whereas AT-3 and AT-5 that included mullite were higher than 1,000. The degree of absorption was AT-4 > AT-2 > AT-1 > AT-3 > AT-5 in order and the correlation between the degree of absorption and firing temperature of earthenware displayed a positive correlation. Extraction amount of oxalic acid which was used for the removing iron oxide was AT-1 > AT-2 AT-4 > AT-3 > AT-5 in order. and the ion extraction data displayed that there is a positive correlation with absorption level. However AT-1 and AT-2 which were fired at lower temperature showed that there was no correlation between the ion extraction characteristics and absorption level. Ion extraction of citric acid produced little amount compared with the one of oxalic acid, yet it caused less damage to earthenware than oxalic acid when it applied. The result of ion extraction level in the absorption test displayed that Fe had higher level than in Si, Al from the test for both oxalic acid and citric acid. Based on the regression analysis of the data from the previous studies, the physical characteristics of the earthenware and ion extraction level, further studies will be conducted on the predicting technique on the extraction characteristics of major elements of earthenware samples for the conservation in future.

This research aims to understand the precise character of relics based on literature search and material analysis of the jade excavated from the first buried place of King Jung-jo, and to assess the level of damage through non-destructive diagnosis. Furthermore, scientific conservation treatment was used to restore the original shape of the excavated jade. According to literature search, the excavated jade is known to be jasper, but material analysis showed that it was as a serpentine with the mineral composition of antigorite. Infrared thermography analysis to assess deterioration showed that the internal damage is the result of the interstices developed along the boundary surface of the obtained jade. For conservation treatment of the damaged area on the surface, the jade was filled with a mixture of plaster and glue, and covered with a mixture of acrylic paint and gloss medium for protection, and color was adjusted.

The purpose of this study was to investigate the material characteristics of black wares excavated from Yongyeon-ri, Damyang and to clarify the correlation of the factors that develop black coulor compared with black wares excavated from other regions. As a results of absorption rate, colour coordinate, compositional mineral, section analysis and contents showed high correlation between the kilns and the waste dumplings, indicating that they were made using the same materials. Second, comparing the microtextures and contents of the glaze layer with the excavated sherds from other kilns, a characteristic coagulation phenomena of iron oxides were not observed in Yongyeon-ri and Gilmyeong-ri, and it was considered that the material, mixing ratio, and firing environment were different from those of Bonggok-dong. In addition, statistical analysis using the major components revealed that the bodies of Yongyeon-ri were highly correlated with those of Bonggok-dong, which is nearest to the region, and similar to Gilmyeong-ri in the glaze layer. The characteristics of colorant were different depending on Fe₂O₃ content and K₂O content also contributed to the classification of the composition of each excavated kiln. Conclusionally, it can be seen from the scientific analysis that the colour of black wares excluded from different regions is materially different from that of iron oxide, the coloring condition, and the firing environment.

Antifungal and insecticidal activity of Korean traditional medicinal plants was carried out to develop natural material for the development of organic cultural heritage conservation. As a result, Phellodendron amurense fruit was finally selected as a candidate of antifungal and insecticidal natural material. An novel active compound was purified from the ethylacetate fraction of Phellodendron amurense fruits using silica gel and Sephadex LH-20 column chromatography and PTLC. The compound was obtained as yellow oil form; UV ${\lambda}_{max}$(MeOH): 260 nm. The chemical structure of novel compound was determined as (4'-ethyl-2'-methylfuranyl)-6-methoxy-7-methylnona-2E,4E,6Z,8E-tetraenoic acid on the basis of various NMR experiments including $^1H$- and $^{13}C$-NMR, HMQC, HMBC and ESI-mass spectrum.

Major and trace elements and cross section textures of the large-sized jar-coffins excavated in the Young San river area have been analyzed for categorization according to geochemical characteristics of the raw materials. As results, we have found out that the jar-coffins of the Oryang-dong and Ungok-dong have very similar characteristics, and those of Songwol-dong and Jangdeung show distinguishable characteristics from the others. In addition, similar characteristics have been detected in some U-shape jar-coffins from several sites such as Oryang-dong, Ungok-dong, Sinchon-ri, Mansu-ri and Yeon-ri posess on trace elements and cross section texture. These results indicate that there was active physical migration although the detail route of the physical migration is unclear at current stage.

In order to examine the constituents and weathered state of a lacquer specimen, analysis of the organic materials was conducted using py/GC/MS(pyrolysis-gas chromatography-mass spectrometry). The samples were obtained from the lacquered wooden sheath of a long ring-pommel sword excavated in the Imdang No.1 ancient tomb constructed around the Proto-Three Kingdoms period. In direct py/GC/MS, the sample and the dried Asian lacquer showed similar chromatograms, while the characteristic compounds of Asian lacquer such as 1,2-dimethoxy-3-pentadecylbenzene were observed in THM(thermally assisted hydrolysis and methylation)-py/GC/MS. In addition, compounds like dimethyl nonanedioate, which presumably originated from drying oil, were also detected. Furthermore, the detection of oxidized catechols in considerable amount indicated that the degradation of lacquer is estimated to result from the oxidation of urushiol. Therefore, it is suggested that the lacquered wooden sheath was prepared using Asian lacquer and drying oil, and that the lacquer layer was considerably oxidized over the long burial time.

In this paper, we divided domestic and foreign digital cultural activation policies into four types. We also described projects of each policy and analyzed the limitations of the policy. Finally, we suggested solutions to overcome these limitations. Changes in daily life caused by the recent development of 5G network technology, augmented reality, and virtual reality technology have brought many changes in the way of preservation and utilization of cultural heritage. In particular, digital technology is used for digitization of cultural heritage, storing, and managing digital data, digitally restoring cultural heritage, and enabling time, space, multi-sensory experiences. For this purpose, new policies was required to utilize this. This study divides domestic and international digital heritage policies into digital infrastructure construction, sharing and communication platform construction, public relations, and demonstration contents production support policies. This study is meaningful in classifying the fields of digital heritage policy and introducing digital heritage policy trends. It is also meaningful to suggest ways to improve digital heritage policies through analysis of domestic and foreign cases.
