In museums, exhibition content focuses mostly on cultural heritage's historical values and functions, but doing so tends to limit visitors' interest and immersion. To counter this limitation, the study developed an experiential media art exhibition fusing bronze mirrors' traditional production technology and modern conservation science. First, for the exhibition system, scientific cultural heritage contents were projected on the three-dimensional (3D) printed bronze mirror through interactions between motion recognition digital information display (DID) and the projector. Then, a scenario of 17 missions in four stages (production process, corrosion mechanism, scientific analysis and diagnosis, and conservation treatment and restoration) was prepared according to the temporal spectrum. Additionally, various media art effects and interaction technologies were developed, so visitors could understand and become immersed in bronze mirrors' scientific content. A user test was evaluated through the living lab, reflecting generally high levels of satisfaction (90.2 points). Qualitative evaluation was generally positive, with comments such as "easy to understand and useful as the esoteric science exhibition was combined with media art" (16.7%), "wonderful and interesting" (11.7%), and "firsthand experience was good" (9.2%). By combining an esoteric science exhibition centered on principles and theories with visual media art and by developing an immersive directing method to provide high-level exhibition technology, the exhibition induced visitors' active participation. This exhibition's content can become an important platform for expanding universal museum exhibitions on archaeology, history, and art into conservation science.

The Bigyeokjincheolloe (bomb shell), a scientific cultural heritage, has outstanding historical value for sustaining a gunpowder weapon of Joseon. In this study, the bomb shell was modeled through three-dimensional (3D) scanning centered on the external shape and 𝛾-ray radiography-based on the internal shape. In particular, to improve the contrast in the radiographic image, optimization and image processing were performed. After these processes, the thickness of the inner wall (2.5 cm on average) and the positions of the three mold chaplets were clearly revealed. For exhibition purposes, the 3D model of the bomb shell was output to a 3D printer and the output was rendered realistic by coloring. In addition, the internal functional elements, such as Mokgok, fuse, mud, gunpowder, and caltrops, were reproduced through handwork. The results will contribute to the study of digital heritages in two ways. First, the internal and external shapes of the bomb shell were modeled by fusing two different technologies, namely, 3D scanning and 𝛾-ray radiography. Second, the internal shape of the bomb shell was constructed from the original form data and the reproduction was utilized for museum exhibitions. The developed modeling approach will greatly expand the scope of museum exhibitions, from those centered on historical content to those centered on scientific content.

최근 우리 사회 전반에서 융복합의 개념이 새로운 가치 창출의 가능성으로 주목받게 되면서, 지식 통합에 대한 요구도 점차 확장되고 있다. 지식과 학문 분야에서 시대적 요구가 변화함에 따라 인재가 갖추어야 할 역량은 물론, 새로운 인재를 양성하기 위한 교육의 패러다임도 바뀌고 있는 것이다. 특히 이공계 대학에서는 전공 지식의 습득을 넘어, 종합적 사고력과 협동 학습 능력을 갖춘 인재 양성을 목표로 '학제 간 융복합 교육'이 확대 실시되고 있는 추세이다. 전공 지식과 현장 실무 능력을 강조함으로써 취업률을 높이는 것만이 아니라, 학생들에게 발견적 창의적 융합적 사고의 바탕이 되는 인문학적 교양과 세계관에 대한 이해를 제공하기 위해서이다. 그러나 현재 전공 및 교양 교육 차원에서 개설된 융합 교과목의 대부분은 타 학문 분야의 지식이나 이론을 소재나 화제로 활용함으로써, 단편적인 지식 습득 차원에 머무르는 경향이 강하다. 이에 본고에서는 과학기술 분야와 인문학 분야의 지식을 균형적으로 통합하여 종합적으로 사고함으로써, 지식 습득에서 한 단계 더 나아가 지식을 응용 재창조 할 수 있는 '융합형 교육 프로그램'을 구안(具案)하였다. 이 프로그램은 문화콘텐츠의 창조를 전제했을 때 유용한 '과학기술'과 '문화 원형'에 대한 이해를 제공하고, 습득된 지식을 가치 있는 결과물로 도출하기 위한 방법으로 '스토리텔링' 학습을 제안한다. 이를 통해 학습자는 과학 기술과 인문 분야를 융합할 수 있는 매개인 '과학문화콘텐츠'를 구성하기 위한 교육을 제공받게 된다. 이로써 전공 지식에 대한 탐구와 응용을 시도하는 가운데, 논리적 창의적 사고를 진작하게 될 것이다. 더불어 그간 과학과 인문학이라는 두 영역을 대상으로 한 '다학제적 교육'이 갖는 한계를 극복할 수 있으리라 본다.

The archeological remains usually exist in some excavated ancient soils. The ancients oils are buried in underground with the environmental, biological and social facts for circumstantial evidence at past times. Consequently, it is very important thing to carry out scientific analysis of the ancient soils side by side with archeological study. In this study, we accumulated some basic data for scientific analysis of 5 kinds of ancient soils excavated at Wanggung-ri, Iksan city. So we obtained some characterizations of organic chemical source, ancient parasite egg, and some seeds in the soils. The organic sources showed the content of high organic material as 7~22%, and strong acidic condition as pH 2~6. It is indicated that Wanggung-ri soils have included so many organic materials from the degradation of biological remains. Most of all, we searched a lot of eggs of parasite Trichuris trichiura and so it is possible that this area had been a ancient toilet at that times. The more scientific analysis of the soils will be showed us about the utility of the area, ancient dietary life style, ancient environment and ancient human diseases.

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.

This study analyzes six slags excavated from the iron making site in Gogi-ri, Namwon, Korea to understand the characteristics of the ruins, and to confirm the iron making process performed at the time. The chemical components of the iron making by-products from the Gogi-ri site were analyzed, and the findings indicate total Fe contents between 23.24% and 37.56%, which are lower than the typical total Fe content found in ancient iron making processes. The deoxidation agent contents of the slags ranged from 43.88% to 58.13%, which are higher than the typical deoxidation agent content of ancient iron making processes. The high content suggests smooth separation between iron and slags, and TiO₂ detected from the site suggests the use of materials with high titanium content in the iron making in the region. As for the microstructures of the slags, some slags have long pillar-shaped fayalites, while others have pillar-shaped wüstite along with ulvöspinel. Slags from the forging furnace show hammer scales created by both the earlier stages and later stages of forging work. The findings suggest that the iron making site in Gogi-ri, Namwon, Korea used to be an iron making facility where a full range of iron making process was carried out ranging from smelting to forging, and the ironmakers used a wide array of technologies to manufacture iron products.

The study, iron-making process was examined through the scientific analysis of six by-products that were obtained during iron making at the Songdu-ri site in Jincheon. The total Fe content of the slags excavated from the Songdu-ri site was 36.29-54.61 wt%, whereas the deoxidation agent was 26.48-49.08 wt%. The compound analysis result indicated that fayalite and wüstite are the main compounds in slag. Furthermore, the microstructure analysis result confirmed the presence of fayalite and wüstite in the slag. It can be inferred from the flat shape in a bright matrix structure of the hammer scales that forging was performed in the latter stage. The Raman micro-spectroscopy results confirmed that the surface was hematite (Fe₂O₄), middle layer was magnetite (Fe₃O₄), and inner layer was wüstite (FeO). The presence of smelting and smithing slags, spheroid hammer scales, and flake hammer scales suggests that at the Songdu-ri site, iron-making process is carried out by division of labor into producing iron bloom through direct smelting, refining and forge welding, and ingot production.

We have analyzed the ingredients of 17 pieces of Bronze Age bronze ware, and an additional 22 pieces of Koryo and Chosun dynasty bronze ware. We have also conducted analysis of the extraction sites where these bronze ware items were found. For analyzing the main ingredient the bronze ware items have been divided into 3 groups - Cu-Sn(70?75:20), Cu-Pb-Sn(70:10:10), Cu-Pb-Sn(60:10:20) type respectively. In tile cases of the Cu-Pb-Sn groups the division comes down to differences in the Cu content as the main component, and elements such as Ni, Fe, Co contribute as a micro ingredient. The geographical and periodic characteristics of ancient bronze ware items show that theircompositional element changes from Cu:Sn to Cu:Pb:Sn and the Cu content decreases with the period,while the Pb content increases with the period. Bronze ware items from Suchon Ri, Gongju (that were used in 3 B.C.) form very different categories from 3rd ${\~}$ 2nd B.C.. They additionally formed very different categories from those bronze ware items analyzed in this research. These bronze ware itemsare shown to be geographically close and periodically overlapped, but made of a new elemental composition. This shows an inflow of a production technical culture present in the new bronze wares. The main component content of Cu is lower, and the Co and Fe contents (as microelements) are much higher than that of other bronze ware items. Such facts showthat those bronze ware items used completely different materials from bronze ware items in other cultural areas, or that there were differences in smelting techniques In the places where ancient bronze ware items have been extracted, it is presumed that the materials originated from the southern parts of Korea andnorthern parts and southern parts of China. .As more bronze ware scientific research is compiled one can conclude that that there will be enough scientific evidence to study the Bronze Age culture of Koreasystematically.
