  • The Buyeo National Museum was requested conservation treatment for wooden objects excavated from three Baekje archeological sites: Neungsan-ri, Ssangbuk-ri, and Gungnamji Pond. Prior to conservation treatment, analysis was conducted to identify the species used. The results of the analysis revealed wood from diverse species of trees including Hard pine, Cryptomeria japonica D. Don, Zelkova serrata Makino, Quercus spp., Platycarya strobilaceae S. et Z., Castanea spp., Torreya nucifera S. et Z., Taxus cuspidata S. et Z., and Salix spp. A high percentage of the objects were made of Cryptomeria japonica D. Don., a species native to Japan, which indicates that exchange with Japan was active at that time. Among the wooden objects, we analyzed lacquer fragments from six pieces of lacquerware, and the characteristics of the lacquer fragments were peculiar to specific artifacts. Most of the fragments were thicker than 100 ㎛. Pure lacquer and mixed black pigment were used. Infrared spectroscopy of the lacquered wooden fragments revealed that they had a very similar absorption band as refined lacquer, confirming that they were painted with lacquer. For their conservation, we immersed the objects in a high molecular weight aqueous solution of PEG#3,350 (10% → 50%) to strengthen them before vacuum freeze-drying.

  • Cellulose nitrates were used for folklore artifacts(ornamental beads and pipes in hatstrings, frames of eyeglasses, ornamental eyeglass cases, headband ornaments, and jeogori buttons) between the 19th and 20th centuries; however, they are susceptible to cracking, crazing, embrittlement, and crumbling due to deterioration. To consolidate and adhere deteriorated cellulose nitrate folklore artifacts, water-soluble acrylic emulsion adhesives were investigated. For consolidation, Plextol D 498, which has the lowest viscosity in low concentrations, was used. In adhesive films whose glass transition temperature(Tg) is lower than room temperature, the tensile stress and modulus decreased and the strain increased; therefore, the flexibility was high. The Plextol D 498 and Plextol D 498 and Dispersion K 52 films maintained their adhesiveness and flexibility after artificial-sunlight-accelerated ageing, and Plextol D 498 and Dispersion K 52 films hardly caused yellowing. Plextol D 498 was the most stable for accelerating ageing. A low concentration of Plextol D 498 emulsion resulted in the best permeability on the surface of cellulose nitrate, compared with other acrylic emulsions. To prevent ornamental hatstrings from cracking, crazing, embrittlement, and crumbling, a Plextol D 498 emulsion was used. After applying low concentrations(1%, 3%) of the emulsion to consolidate the fragments and high concentration to adhere the fragments, the ornamental hatstrings were protected from crumbling by deterioration, and their fragments were well-adhered. To preserve it from deterioration by oxygen and humidity, the treated ornament was sealed with an oxygen-barrier film using a low-humidity oxygen scavenger.

  • 3D printing technology has been actively applied for the restoration of cultural properties. However, its application to the restoration of glass cultural properties has not yet been reported and thus requires further study. In this study, 3D printing technology was used to restore a defective part of a glass sarira bottle that forms an element of a series of sarira reliquaries commissioned by Yi Seonggye (known as King Taejo after founding the Joseon Dynasty) that was excavated from Geumgangsan Mountain (designated as Treasure No. 1925) and is currently housed at the National Museum of Korea. The defective area was reproduced using 3D printing and the printed reproduction was reproduced again using an epoxy resin. This latter piece was used as the restoration component rather than the 3D printed element. After the completion of the conservation treatment, the materials used for the 3D printing were compared with transparent materials used to restore ceramics to evaluate their usability and stability. A total of five specimens were produced, including from photocurable resin made by a stereo lithography apparatus (SLA), epoxy resin, acrylic resin, and more. They were exposed to UV for 96 hours to test for yellowing. Of the two specimens made of photocurable resins and exposed to UV, one was sprayed with a UV blocking agent but the other was exposed as-is. The UV exposure test showed that the specimen made by the SLA and sprayed with a UV blocking agent and the specimen made of epoxy resin were stable in terms of yellowing with a change in the b-value was less than 1. They are thus considered to be suitable materials for the restoration of glass cultural properties. Such glass cultural properties are often diverse in shape and their restoration can be difficult as they generally consist of a range of complex parts that hamper restoration. In this regard, diverse materials should be considered when selecting materials for the restoration of glass cultural properties.

  • This paper described the types and characteristics of educational programs in major natural history museums of the world. Data were collected from the websites, annual reports, and written materials of the Natural History Museum at London, Australian Museum at Sydney, Field Museum of Natural History at Chicago, Smithsonian Museum at Washington D.C, Royal Tyrrell Museum at Canada and American Museum of Natural History at New York. As the result of this study, we presented ten types of educational programs, which were moveable museums, workshops, lecture/courses, festival/events, discovery activities, scientific exploration/research projects, field trips, youth curators/internship, loan materials and camp/tours. We also described the examples equivalent to each program type. The characteristics of educational programs provided by museums as informal learning settings were analyzed in terms of their themes, participation levels, connection with exhibition, relation to curriculum, and learning activity levels. Information in this paper will assist science teachers, museum educators and curators: (1) to design and implement various types and contents of educational programs; (2) to use characteristics of educational programs to assess and develop them; (3) to make important contributions to science education that involves the introduction of various scientific aspects and collections to the public, and the use of programs for science learning and teaching coherent to existing curricula.

  • This paper is studios about a new role model of 'Korea Comics Museum' which will be extended Into 'Korea Institute for the MANWHA & Moving Image Content's planning. Scanning all activities of 'Korea Comics Musium' until now, I'd like to suggest how to promote the comic industry by a Comic Museum's practical contribution. It needs conditions for doing its intrinsic activities, faithfully, most, than a value of Bucheon's city brand or superiority in industrial aspects. And also it is Important that establishing collection policy for spreading excellence of Korean comics, internationally and setting structure for mating network among the museums in abroad and institutions related comic industry. Finally comic museum has to equip a new working structure, furthermore, perform exhibition planning and cultivating system of artists and for this, it needs its own independent organization.

  • Today, visitors of art galleries like to share their life in their communities than interacting with artwork. Meantime, image sharing of an exhibition on social media has become more important than actual watching of the artwork. Accordingly, most of the galleries have started paying more attention in organizing an exhibition environment for proof-shots to attract more visitors. We initially conducted research about the internet environment from the late 1990s to the recent years and analyzed the changing watching patterns of the exhibition since the advent of social media. Secondly, for empirical case analysis, we selected 'Plastic Fantastic' held in D-Museum as the target of analysis. The analysis targeted 500 recent postings that were discovered on Instagram on March 4, 2018, as 'Plastic-Fantastic'(in Korean). The methods of analysis included classification types of image, hashtag, and text on Instagram and were arranged in an order of relation to the exhibits. Based on the image analysis, 44.2% of the images involved exhibition displays; the others included a person or other goods. Based on the results of the text and hashtag analysis, only 3.6% of posting included information about the exhibition and 56.4% had non-related inflow hashtags only with image. The behavior of these shares is likely to gradually lose the inherent meaning of the exhibition and to the value rather than imparting the artistic thrill that viewers derive from art. Exhibition should try to seek deep interaction between the display, audience, and social media users, rather than encouraging the visitors to take proof-shots.

  • The textile remains have been affected largely by environmental factors including microorganisms because they were composed of organic compounds to be easy to damage. So, we selected 8 strains of the 131 isolated strains from museum environments and textile remains by high pretense activity, and identified them for measuring the antibacterial activity of Gingko biloba extracts. They were identified Genus Arthrobacter spp. 3 strains (Arthrobacter nicotiannae A12, Arthrobacter sp B12, Arthrobacter oxidans B13), Cenus Bacillus spp. 2 strains (Bacillus licheniformis D9, Bacillus cereus D33), Genus Pseudomonas spp. 2 strains (Pseudomonas putida A24, Pseufomonas fluorescene C21) and a Genus Staphylococcus sp. 1 strain (Staphylococcus pasteuri D3) as closest strains through the blast search of NCBI. Though antibacterial activity of the extracts of Gingko biloba leaves as MIC was lower than that of other pharmaceutical antibiotics. However the extracts was crude extracts, the extracts might have good antibacterial against most of the isolates from museum. Especially, the antifungal activity of Gingko biloba is known previously, the extracts of Gingko biloba leaves has possibility of usage as a good natural material for conservation of remains.
