The old bridge of Woljeong-gyo, which has the fluvial history and culture, represents the ancient construction and civil engineering techniques. It is the oldest stone bridge in Korea and currently restored with its vicinities. In this study, the experimental model was used to analyze the hydraulic characteristics, the local pier-scour depth without scour protection, and the stability of riprap protection using the old grid type panels and stones for Woljeong-gyo of the study area. The water levels were increased around 30cm due to the restored bridge piers and foundations and the effects went up to 200m upstream. The maximum scour depth of 5.4m was measured and the scour protection tests were performed with the riprap size calculated using empirical equations and the existing scour protection range. The riprap of the existing scour protection in the upstream side was broken away, while the riprap of extended scour protection was very stable for the design flood condition of Woljeong-gyo area.

The purpose of this study is to examine the possibility of science education using Korean TSK(Traditional scientific knowledge). In this study, we have developed five Korean TSK units including science concepts, historical knowledge and cultural experience and applied them to 10th graders. The five units are as follows: (1) Calendars(western and eastern), (2) Our traditional sundial, Angbuilgu, (3) A great scientist in the King Sejong Era, (4) Data interpretation of ancient record of natural phenomenon in Korea, and (5) Gyeongbokgung Palace. The analyses included a pre- and post test of students' perception, classroom observation, students' activity sheets, and interview. The results show that the students' perception of Korean TSK has changed toward recognizing the value of Korean TSK as a kind of natural science. They expressed their expectation of Korean TSK in scientific, practical, and emotional perspectives, wherein some students thought the practical and emotional perspectives of Korean TSK as non-scientific characteristics. Students showed five types of worldview about the relationship between Korean TSK and WMS(western modern science). Most students favored and cherished the Korean TSK but at the same time, they were confused about its scientific value. The results support the rethinking of the meaning of science and what students learn in school. We should consider how we teach the Korean TSK to students. It is important that a profound research of the Korean TSK should be continued to make our science education varied.

The enlightenment project raised in both Korea and China during the modern period worked as a part of the patriotic enlightenment movement against the imperial powers. Among them, "boy" appeared as the subject of enlightenment, and "sea" appeared as a medium. Specifically, through "Boy Discourse," Liang Qi Chao ultimately envisioned a nation for "subjects", and Choi Nam-seon also seeked to overcome the national crisis as "New Korea" and join the ranks of powerful nations. Liang Qiqiao proposes the concept of a "Boy Nation" and an "Old Nation" through boy discourse, and wishing for the development of the "Boy Nation" through "proficiency training". Choi Nam-seon also recognized that the future of the nation depends on "boys", influenced by Liang Qi-qiao's discourse on boys, and argues that Choseon should cultivate skills to become a "Boy Nation". In addition, Liang Qi-chao and Choi Nam-seon actively spread the "boy discourse" through the creation of poetry. Liang Qi Chao introduced the world's geography and history through poetries related to the sea, while at the same time inspiring a sense of challenge to recognize and pioneer the sea as a pathway that connects the world in a broad sense. Namseon Choi also created a poem that directly linked "the sea" and the "boy" to promote the "adventure at sea" and "the progressive spirit of the sea and the boy".

Lacquer is one of the most widely used natural resin in East Asia since Neolithic Age. As a major ingredient of lacquerware, lacquer is waterproof, insect-proof and rot-proof to be durable and anti-abrasion, generally utilized for mainly painting purpose. According to lacquerware excavated from several sites of Japan and China, lacquerware seems to appear in Neolithic Age. On the other hand in case of excavation research in Korea, lacquerwares are found after the Bronze Age. The initial purpose of lacquer is estimated to be adhesive, regarding the literatures mentioning bitumen(Yeoksceong ), animal glue(Kyeo) and egg alumen(Nanbaek). Especially piece of jar coffin unearthed in Pyeongtaek Daechu-ri site had trace of restoration by lacquer and hemp as an evidence of lacquer for adhesion in Pre-Three Kingdoms period. Since then a trend to restore the broken ceramics with lacquer and decorate with golden foil lasted especially in Joseon Dynasty. In the field of gold plated lacquer method, mother-of-pearl inlaying technique for lacquerware and restoration of buildings, lacquer is still used as adhesive. Due to matter of reversibility lacquer is being avoided for conservation and restoration of cultural heritage. Lacquer as a traditional material for adhesive since ancient times, however, has advantage in adhesion strength and durability. Because synthetic resin adhesive has problem of emission of volatile organic compounds and aging over time, lacquer receives attention recently. On the contrary, by combination adhesive from mixing lacquer and animal glue, already proved the possibility of applicability and chemical modification. A research to utilize lacquer as modern paint or functional material is also conducted continuously also in China and Japan. To put traditional material into practical use and modernize, chemical research from the molecular level of the lacquer is necessary in the near future.

Red ocher, red lead or cinnabar has been as red colorant for ages. Cinnabar of the red pigments has been highly regarded as a valuable ingredient because it represent a symbol of exorcising and a haute image. It was used as a pigment of painting and mural painting, bowl, clothes, rock writing, gravestone, etc. It is powder which dissolves in perilla oil or glue before using. Because it is high-priced, the use of cinnabar may be limited to the privileged class. Therefore, red ocher or red lead was used instead of cinnabar. "Gongsagyunmunrok" demonstrated that government official's gravestonea has been painted red by two colorants in the period of the Goryeo dynasty. However, cinnabar may be used to paint gravestones for the first time in the period of the Three States because it has been transmitted since the times. This study discuss the results obtained from an analysis of the pigments used on the red pigments of the Stone Monuments. The results can be briefly summarized as below; First, the microcrystalline structures seen on the surface section of analyzed pigments, samples of which were taken from various parts of red pigments show that different sizes and shapes of pigment particle. Second, a result of the analysis on the composition and structure of the pigments shows that the main components in their composition are : Red pigments - Red lead($Pb_3O_4$), Cinnabar(HgS) and Hematite($Fe_2O_3$) White pigments - Calcite($CaCO_3$) Especially, we knew that red Stone Monuments were found to be natural mineral pigments, which were used as a singular or a mixture.

The book is a footnote of life and memory, a sign of knowledge and intelligence, including divinity and reason, idols and destruction, praise and curse, arrogance and prejudice, truth and falsehood. The past emperors, monarchs, priests, and rulers have been controlled or slaughtered by censorship and prohibition, burning and destruction, etc. In ancient history, archaeology, war history, cultural history, and library and information science, many studies have been conducted on the burning and destruction of books, but the Western perspective is dominant, and there are nationalistic approaches and logical leaps. This study traced the truth about the destruction of the Royal Library of Alexandria in Egypt, destruction of the Baghdad libraries by the Mongol Empire, and burning more than 200,000 volumes of Korean historical documents of Japanese Government-General in Korea among the major bibliocausts with many mysteries and controversial issues in the East and West. As a result, the Royal Library of Alexandria is most likely destroyed under the rule of the Roman Empire. The massacre of the Baghdad library by the Mongolian army is a historical fact, not the manipulation and extreme exaggeration of western society. And Korean historical documents have been stolen and burned by the Government-General of Chōsen for 35 years and should be recognized as '200,000 + α'. Lastly, On the premise of excavating historical materials, research to investigate the truth behind the blibiocaust or libricide should be continued.

Ajaeng is the bowed string instrument among zither instruments in East Asia, which has a circular form to date, and it has established itself as an important instrument in today's creative Gugak along with traditional music. Looking at previous prior studies, musical instrument studies have not been actively conducted due to insufficient data from musical history studies, and this study looked at the origin, form of musical instrument, and performance methods of zither bowed string instrument through historical records of Chinese Yazheng and music drawings. The analysis of various documents showed that Ajaeng originated from an ancient Chinese traditional musical instrument called Chuk. In terms of the performance style, the Chinese Yazheng had different musical forms depending on the purpose and location of the performance, and there was a method of standing up and fixing the musical instrument horizontally to the ground. Ajaeng in Korea has been handed down without much change in the form of musical instruments introduced in China during the Goryeo Dynasty and the way they sit on the floor and play on a pedestal. Through this study, we hope that it will help to preserve and develop traditional music and Korean traditional musical instruments by enhancing understanding of musical.

The restoration of cultural heritage materials is an important research theme. This study improved the existing cultural heritage restoration method and attempted to establish a restoration system for cultural heritage data based on historical documents and visual materials. Recognizing the limitations of existing studies, this paper attempted to restore cultural heritage data through interdisciplinary research. In addition, 3D restoration was carried out after restoration in 2D form based on literature documents rather than existing visual sources. The object of restoration that was selected was "Jeol," which represents the power of the king of Koguryo. Koguryo's Jeol is a type of flag. Jeol appears in the mural in Anak Tomb No. 3. Rather than using only photographic materials of murals, the restoration was carried out through cross-validation of literature data and materials on archaeological art history. This is important in that the restoration carried out in this study is an accurate restoration with a historical understanding based on the literature of the relevant cultural heritage. In this study, a restoration process based on historical records was established. A 3D restoration process was performed by adding and applying visual materials after the object was first shaped based on the literature data. Restoration based on literature and visual materials was carried out based on interdisciplinary research. Therefore, this study aims to build a digital restoration system for cultural heritages and to contribute to spreading the 3D digital restoration research of cultural heritages that can be applied to various platforms.
