Cultural assets excavated in historical areas have their own characteristics based on the background of the times, and it can be seen that their patterns and characteristics change little by little according to the history and the flow of the spreading area. Cultural properties excavated in some areas represent the culture of the time and some maintain their intact appearance, but most of them are damaged/lost or divided into parts, and many experts are mobilized to research the composition and repair the damaged parts. The purpose of this research is to learn patterns and characteristics of the past through artificial intelligence neural networks for such restoration research, and to restore the lost parts of the excavated cultural assets based on Generative Adversarial Network(GAN)[1]. The research is a process in which the rest of the damaged/lost parts are restored based on some of the cultural assets excavated based on the GAN. To recover some parts of dammed of cultural asset, through training with the 2D image of a complete cultural asset. This research is focused on how much recovered not only damaged parts but also reproduce colors and materials. Finally, through adopted this trained neural network to real damaged cultural, confirmed area of recovered area and limitation.

In the 1960s, polluted urban streams were covered and paved in concrete. Rivers became sewers buried under road. As a result, wildlife habitat was lost and the open stream space was gone. In the 1990s, there was a movement for restoring urban streams to enhance the quality of life of inhabitants. Chungkye Stream, whose covering began from early 1950s and ended in 1977, is now in the process of restoration together with the Central Business District (CBD) Redevelopment Plan. However, as the construction proceeds, several problems were raised, and serious controversies resulted. Therefore, this study aims to investigate the validity of the approach of the Chungkye Stream Restoration Project through a literature survey and a site survey, and to present the improved alternative. Ultimately, the study aims to contribute to present references or guidelines for similar urban stream restoration projects. The Chungkye Stream Restoration Project has some of the following problems. First, the construction should be done based on the long-term urban redevelopment plan. Second, the construction period should be extended to restore urban streams. Third, the cultural asset conservation plan should be implemented. In order to fulfill the anticipated purpose, the above mentioned problems need to be solved.

After selecting five types of adhesive epoxy resin for metallic cultural assets such as $Araldite^{(R)}$ rapid type, $Devcon^{(R)}$, $Araldite^{(R)}$ SV427+HV427, $CDK^{(R)}$520, $Araldite^{(R)}$ AW106+HV953 which had already been studied, this paper approached more closely the problem of yellowing and the signal of aging with time passing by connecting the problems with the safety of metallic cultural assets. The change of physical properties according to the change of state of epoxy adhesives was investigated through the change of flexural strength and the change of surface hardness by artificially providing the possible environmental change factors such as ultra-violet ray, and acid base, and how the epoxy chemically changes in its ingredients by the environment was analyzed through FT-IR. As a result of the experiment, for the most part of adhesives brought about the physical change of flexural strength, the change of surface hardness, and the chemical change of chemical ingredients as the product of alcohol, which were respectively different according to the time of ultraviolet irradiation, and acid base change. Under most of the conditions, SV427+HV427 and $CDK^{(R)}$520 were fairly stabilized under each condition of weatherability, but it seems that they should be refrained from being applied in case that the area to restore is thin and wide because the degree of flexural strength of themselves is low. Also, it is found that the preservation environment is very important not only for artifacts but also for the preservation of resins sused for preservation treatment.

Modern and contemporary cultural assets are defined as a collective term for tangible historical and cultural assets produced in the modern and contemporary period (around the opening of Joseon to the present) in Korea. Among them, rickshaws have been used as a major means of transportation for about 40 years since the opening of the ports in Joseon. The repair process for rickshaws divides the rickshaw into three parts, namely the body, the cover, and the wheels, applying a plaster treatment process by referring to the outcomes of the condition assessment and material analysis for the metal, wood, fiber, and paint used. Overall, the repair process is carried out through dry/wet cleaning, joining, stabilization, reinforcement of damaged parts, and other restoration treatments, which reveal metal decorations and patterns on the scaffolding (flowers, arabesque patterns, etc.) that were previously not observable with the naked eye, while also adding to the stability of the artifact. In addition, props were produced to ensure the artifact's safe exhibition.

The purpose of this study is to analyse the properties of natural mineral pigments used in restoration and conservation of cultural assets. For this study blue-based pigments that are sold in market were selected. The component analysis using by XRF and XRD shows that blue pigment consist of Azurite. And each specimens were evaluated particle size, chromaticity, specific gravity and oil-absorption according to rating system of pigments particle size. Results show that the value of L* increase with the decrease in particle size. The results suggest that the physical properties which is specific gravity, oil-absorption and chromaticity depend on the particle sizes of pigments. When it comes to particle size of pigments decreased by increasing the number of rating system. In addition, the chromaticity related to particle size. The result from this study expects to be used as useful referencing data for conservation and restoration of cultural heritage and understanding phenomena of the properties according to various particle size of Seokcheong pigment.

The aim of this study is to analyze the research trends on Hanji (Korean traditional paper) in the academic literatures based on the purpose, content, and findings of various studies, and to present a direction for future research. Research papers published in 12 academic journals over the past 51 years (1965-2016) were collected using 167 key-words for the search, and of them, 178 papers were selected for analysis. Statistical analysis of these papers based on year, research content, and discipline to understand and quantify the research trend. Revealed that the frequency of the published research paper was generally proportional by number of research projects in domestic government departments. They also indicated that while there were several studies on property valuation or functionality improvement of Hanji based on experiments, research was lacking in the areas of observation, analysis, case studies, and status survey of Hanji. The present study provides basic data for establishing the direction of research on Hanji.

The traditional village forests in Korea such as Dangsan forests and Bibo forests form unique cultural landscape and they are national cultural assets with histories of more than several hundred years. It is important to have sustainable right to enjoy cultural heritage as well as maintaining its authenticity. Cultural assets are meaningful only when they are managed to succeed to next generations. Dangsan forests and Bibo forests need to be named properly and recognized by society as a precious cultural heritage for many generations to come in order to claim the value as traditional cultural landscapes in Korea. The traditional village forest in Dangin-ri, Wando-gun was composed of a Dangsan forest and five Bibo forests. Although this traditional village forest is large in size, it was not on the report of Cultural Heritage Administration(2005) investigated for 'Village forest of island region in Jeollanam-do'. The objective of this study was to investigate the characteristics of the traditional village forest in Dangin-ri to grant correct name and to enhance its value. In this study the characteristics of a Dangsan forest and five Bibo forests were investigated from 2006 to 2013 for physical features such as size, shape, location, tree species composition, and diameter at breast height(DBH), as well as cultural aspects and tradition. Currently the naming and designation of natural monuments by the cultural heritage administration(CHA) is based on the rule enacted in 1934. Many Dangsan forests were named as evergreen forests. This type of names does not represent the meaning of traditional village forest. It was suggested that this traditional village forest is to be named as 'Dangsan Forest and Bibo Forests at Dangin-ri, Wando-gun'. This traditional village forest needs to reclaim authenticity and rebuild its original appearance by restoration of the disturbed areas, especially in Bibo forest I.

There is often confliction between conservation for protected ecosystem assets and development for various stakeholders at wetland protection areas. The concept of Ecosystem Services can be an alternative solution for the conflicts. This paper attempted to measure and evaluate cultural ecosystem services according to the index evaluation approach. For the evaluation, the paper suggested five indicators of ecosystem cultural services including: inspiration, landscape aesthetics, education, eco-tourism, and heritage. The developed indices of cultural services in this study can be also utilized as a policy support tool for conservation of the wetland protected areas. The result illustrates the ranking and correlation of each indicator of ecosystem cultural services and suggestions for useful means of management policy in wetland protected areas.

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.

Paper cultural asset show various deterioration characteristics and behaviors according to the environmental conditions during the storage. The understanding of the paper itself and its conservation knowledge is thus prerequisite to preserve paper cultural assets and pass them to descendants in a good condition. The Annals of Joseon Dynasty is one of the most important our written cultural assets (National treasure No.151) and it is registered as a UNESCO Memory of the World. The Annals of Joseon Dynasty is composed of 1707 volumes and 1,187 books that were written on the official history of 472 years(AD 1392-1863) from King Taejo to King Chuljong (25 generations). Among them, beewax-treated Annals show severe damages due to the deterioration of wax materials such as breaking, hardening, darkening, discoloring and whitening. Urgent measures should be taken to preserve the Annals and prevent further deterioration. Therefore, a systematic and scientific approach on the conservation and restoration of the Annals of Joseon Dynasty is definitely necessary. So it can be used an example to show how much the preservation science can conserve the paper cultural assets. In this respect, this study focuses on analyzing paper properties and deterioration behaviors of the Annals of King Sejong, the most damaged one, using non-destructive micro analysis techniques.
