"Jocheonillgi", one of the articles left by Jo Heon(1544~1592) whose pen name was Jung-bong, is a travelogue which was written in around 1574~1575 when he was dispatched to Ming as a formal envoy(Giljungkwan). The diary-style manuscript was designated as one of the pieces of the National Treasure 1007. Due to the damage of its binding strings, abrasion, fold, stain, insect and damage on the surface, conservation and restoration was needed. In the process of separation, three more binding strings were found, confirming that the travelogue was rebound at least twice in the past. In addition, the page of 'Yeondoillgi', the original title, was bound inside, confirming that the current cover was revised in the past. As the result of the investigation of base fabric, paper mulberry was found to be the cover, inside paper, lining paper, paper strings. The three kinds of binding string including the current ones was defined to be silk.

Paper relics are affected by a number of complex physical, chemical, biological and artificial damaging factors due to the vulnerability of organic materials. Wet cleaning is a conservation treatment method for removing pollutants from paper artefacts. This study was carried out in order to analyse the effect of wet cleaning on Hanji (Traditional Korean paper made from mulberry trees) which is the main material used in Korean paper relics (historical paper documents). For this study, the color change and folding endurance of artificially degraded paper was analysed before and after immersion wet cleaning. The result showed that washing each twice in 30 minutes is the most appropriate method for obtaining cleaning efficiency and material stability.

This paper aims to study on attribute of interaction between user from cultural capital perspective of Bourdieu who expanded the concept of capital and presented class production and reproduction through 'World of Warcraft' play and analysis. The results of this study is that First, game ability showed properties of cultural capital that embodied, objectified, institutionalized. Second, the types of interaction by difference of cultural capital appeared that lurking, reciprocity, exclusion. This study identified game ability have attributes of cultural capital and that Due to the nature of the interaction for 'Disticion', individual actions are related to the process of accumulating power and contribute to class reproduction.

The Investigation of organisms damaged to papers and cellulose materials of Cultural Property in the Ch'ang Dok Palace The investigation of the airborne fungi, the attached fungi to the papers and cellulose materials of Cultural Properties in addition to the insects inhabiting at the Ku Sonwon Jon, Shin Sonwon Jon and Yonwa ch'anggo in the Ch'ang Dok Palace carried out from Jul. 10 to Jul. 21,1984.The results are summarized as follows ;1. Isolation and identification of the airborne fungi from the three storages were Cladosporium sp., Alternaria alternata, As pergillus cervinus, A. flavus, A. nidulance, A. oryzae, A. terreus, A. versicolor, A. wentii, Penicillium adametzii, P.albicans, P.canescens, P. citreo-viride, P. citrinums, P. decumbens, P. frequentans, P. funiculosum, P.herquei, P.implicatum, P.multicolor, P.nigricans, P.nonatum,P.purpurogenum, P.roqueforti, P.viridicatum, Trichodema viride, Geotrichumcandidum, Curvvlaria lunata, Torula hebarum, T.thermophila, Itersoniliasalmonicolor, Drechsclera avenue, Candida sp., Acremonium sp., and Botrytis sp., It was found that thirty five species in thirteen genera was isolated. Among them, the dominant species was Cladosporium sp., and the order was Penicillium, Aspergillus, Alternaria and so on.2. The attached fungi directly isolated from the papers and cellulose materials of Cultural Properties were twenty-nine species in fourteen genera, namely, Acremonium sp., Albertiniella sp., Alternaria alternata, Aspergillus clavatus,A.niger, A.ornatus, A.versicolor, Botrytis sp., Bysochlamys sp., Carpenteles sp.,Chaetomium globosum, Cladosporium sp., Eurotium sp., Mucor sp., Penicilliumcanescens, P.chermesium, P.citrinum, P.frequentans, P.funiculosum, P.herqueiP .implicatum, P.javanicum, P.luteum, P.purpurogenum, P.thomii, P.viridicatum, Torula thermophila, Trichoderma koningi and T.viride. Among them, the mostfungi distributed on the surface of the papers and cellulose materials was Penicillium and the order was Aspergillus, Alternaria, Cladosporium, Trichodermaand so on.3. The insects collected the three storages were ten genera and ten species including 916 specimens. By classifying the insects collected, the most species of the insects was Stenoscelodes hayashii of 857 specimens occupied about 93% of the total insect. And the other insects were collected as Microgamme costipennisAnobium pertinax, Xenomimetes alni, Anthrenus verbasci, Holoparmecus signatus,Thermobia domestica, Halyomorpha brevis, Drosophila coracine and Brattaorientalis. As described above, it could be known that the most airborne fungi was Cladosporium and the order was Penicillium, Aspergillus, Alternaria in the three storages. And the most attached fungi distributed on the surface of papers and cellulose materials was Penicillium and the other fungi were Aspergillus, Alternaria Cladosporium, Trichoderma and so on. Accordingly, from the results, itwas assumed that the major part of airborne fungi were attached to the papers and cellulose materials of Cultural Properties. The paper and cellulose materials of Cultural Properties in Ch'ang Dok Palace were chiefly damaged by S.hayashii in Coleoptera.

Currently, most of content restoration using artificial intelligence learning is 2D learning. However, 3D form of artificial intelligence learning is in an incomplete state due to the disadvantage of requiring a lot of computation and learning speed from the existing 2 axes (X, Y) to 3 axes (X, Y, Z). The purpose of this paper is to secure a data-set for artificial intelligence learning by analyzing and 3D modeling the stone pagodas of ourinari by era based on the two-dimensional information (image) of cultural assets. In addition, we analyzed the differences and characteristics of towers in each era in Korea, and proposed a feature modeling method suitable for artificial intelligence learning. Restoration of cultural properties relies on a variety of materials, expert techniques and historical archives. By recording and managing the information necessary for the restoration of cultural properties through this study, it is expected that it will be used as an important documentary heritage for restoring and maintaining Korean traditional pagodas in the future.

The purpose of this paper is to clarify the naming creation process of cultural contents based on the violation of selectional restrictions. This is to insist that the violation of selectional restrictions should be significantly considered as a mode of story planning and title naming in the cultural contents such as 'King and the Clown' and 'Ballerina Who Loves B-Boy'. This approach of selectional restrictions is based on the insistence of Chomsky's 'Aspects of the Theory of Syntax' in 1965. His idea had proposed that violation of linguistic rules affects the acceptability in the selectional properties of words and sentences. This focuses on the naming creation of cultural contents by widening his notion between selectional restrictions and the violation of selectional restrictions.

According to damage of papers by the chemical cause, papers become to acidify. Among the 3 kinds of method measuring the acidity of paper, one was nondestructive method measuring the surface of the paper by flat type electrode and the others were destructive methods measuring directly by cold water extract method and hot water extract method. In case of the cellulolytic cultural properties, the latter methods were not applied because those methods must bedissociated papers. To measure the paper acidity nondestructively, we investigated the correlation of the nondestructive method and the destructive methods. The conclusions are as follows. 1) In the relationship of the cold water extract method and the hot water extract method, It was indicated that the pH measured by the hot water extract method was high quality printing paper 0.08, rough printing paper 0.13, and Korean paper 0.29 higher than that by the cold water extract method.2) In the relationship of the cold water extract method and the surface measurement method, It showed that the pH value measured by the cold water extract method was high quality printing paper 1.86, rough printing paper 0.80,and Korean paper 0.58 higher than value that by the surface measurement.3) In the relationship of the hot water extract method and the surface measurement method, It showed that the pH value measured by the hot ABSTRACT water extract method was high quality printing paper 1.78, rough printing paper 0.66, and Korean paper 0.29 higher than that by the surface measurement. From the above-mentioned results, the pH value measured by the surface measurement was need to high about 1.78∼1.86 in high quality printing paper, 0.66-0.80 in rough printing paper, and 0.29∼0.58 in Korean paper and the surface measurement with flat type electrode was very available to measure the acidity of Korean papers actually.

Low oxygen treatment and heating treatment are used to prevent insects in the field of food science. These eco-friendly control methods can be applied to biological control technique in conservation treatment of organic cultural properties. To evaluate material stability, low-oxygen treatment and low oxygen treatment are applied to wood, pigment, paper and textile that are related to historical wooden buildings. As a result, wood moisture content declined after low oxygen treatment. But decline rate is a little, so it can be expected to turn back original state as time passes. And test result on pigment, paper, textile of chrominance and strength of test materials are stable. But after heating treatment, pigments are separated.

This study aims to investigate the applicability of supercritical fluid extraction as a dewaxing technique to restore the beeswax-treated volume of the Annals of the Joseon Dynasty in various deterioration and damage conditions. Thus, this study analyzed the dewaxing efficiency and changes in physical and morphological properties before and after dewaxing, by applying the optimal supercritical fluid extraction dewaxing condition ($70^{\circ}C$, 40 MPa, $CO_2$, Co-solvent 20% DCM, 2 hour) to 3 kinds of beeswax-treated paper with different deterioration rates (dry artificial aging of 10, 20 and 30 days at $120^{\circ}C$). After dry artificial aging at $120^{\circ}C$ for 30 days, the average molecular weight of the beeswax-treated specimen was $1.856{\times}10^5g/mol$, showing deterioration about 80% of the beeswax-treated paper before dewaxing. It was a similar level to the molecular weight of the bees-waxed volume of the Annals of the Joseon Dynasty that has a higher degree of damage. As a result of analyzing the dewaxing efficiency through FT-IR analysis, this study discovered that it was possible to effectively dewax beeswax-treated paper in the range of deterioration 20 to 80% with this supercritical fluid extraction dewaxing technique applied. As a result of analyzing changes in the physical and morphological properties before and after dewaxing, the viscosity tended to decrease to a slight degree, and since no morphological deformation or damage of stencil fibers was found, it was concluded possible to conduct stable dewaxing through this supercritical fluid extraction technique.
