A fact-finding survey of the Demilitarized Zone can be said to be a very meaningful academic survey linked to previous index surveys of protected military areas and municipal and excavation surveys of ruins and military sites on Mount Dora. Not a few ruins were first discovered in this survey, and the locations, structures, and restoration artifacts of the previously investigated ruins were confirmed differently, raising the need for a detailed investigation. In particular, it is noteworthy that various relics from the Paleolithic Age to the Joseon Dynasty were recovered from relics dispersion sites such as Josan-ri and Cheorwon Gangseo-ri in Paju, and Hoengsan-ri Temple Site is also a Buddhist relic in the Demilitarized Zone. However, in the case of some graveyards and relics sites in the Paju region, it was an opportunity to understand the reality that they are not safe from cultivation and development, and the ruins of Cheorwon Capital Castle, Seongsanseong Fortress, Jorangjin Bastion, and Gangseo-ri Bastion were damaged during the construction of military facilities, and an urgent investigation is needed. Also, farmland and hilly areas around the ruins of Jangdan, Gunnae-myeon, and Gangsan-ri have not been properly investigated for buried cultural assets due to small-scale development. Therefore, it is an important time for the relevant authorities and agencies to cooperate more closely to establish special management and medium- to long-term investigation measures for the cultural heritage in the Demilitarized Zone based on the results of this fact-finding investigation.

The Korean cultural heritage protection act, enacted in 1962, is known to have been enacted in imitation of the Japanese cultural heritage protection act. The Japanese law differs from the current law dealing with intangible cultural heritage, folklore materials, and buried cultural properties. The Japanese law was enacted in consultation with the GHQ, and reflected the historical issues at the time of the enactment. Recently, in Japan, GHQ documents have been released and so research on the cultural heritage protection act is carried out. Therefore, it is necessary to understand the meaning and achievements of the Japanese cultural heritage protection act before comparing it with the Korean law. GHQ stipulated the emperor as a symbolic entity in the Japanese constitution and prescribed the country as a liberal democracy. Influenced by this, the cultural heritage protection act was enacted to identify the people's cultural heritage. Accordingly, the cultural heritage protection committee is a private and independent organization in Japan. The committee designates cultural heritage assets, and it operates as the national museum and the cultural heritage research institute. This system was a part of policy changes shifting cultural heritage management to the private sector. Since many cultural heritages are associated with the imperial family, museums were managed by the imperial family. Meanwhile, the Japanese house of councillors persuaded GHQ, which was negative about including intangible cultural heritage in the cultural heritage protection act. The purpose of this idea was to provide the system of the government support for Japanese imperial court music and dance. In addition, folk materials were included with the consent of the GHQ in that they represent the cultural heritages and the academic achievements of the people at the time in Japan. According to the Korean Law, the subject of designation of cultural heritage is the government, and the cultural heritage committee acts as an advisory body with its limited functions. In the early days, the committee confused the concept of intangible cultural heritage and folklore materials. This was because the concepts of cultural property was borrowed from Japanese law and applied to the Korean law without a full understanding. In response, the cultural heritage committee urged the ministry to investigate the current situation in Japan. The cultural heritage committee, mainly consisting of folklore scholars, was confused about the concepts of intangible cultural heritage and folklore materials, but the concept became clear when the enforcement regulations of the cultural heritage protection Act was enacted in 1964.

Glass pieces excavated from Mireuksa Temple dated $7^{th}$ century A.D. were characterized by chemical composition, specific gravity and melting point. Lead isotope ratios of lead glasses were also compared with those of lead ore to attribute which lead ore was delivered for making lead glass. It was known that some lead glasses found in Japan were similar with those of Mireuksa Temple as comparing the data of chemical composition and lead isotope ratios. Characteristics of lead glass from Mireuksa Temple Thirty five glass pieces of Mireuksa Temple were analyzed for five oxides and found that all was lead glass system(PbO-$SiO_2$) with the range of 70~79% for PbO and 20~28% for $SiO_2$. The concentrations of oxides such as $Al_2O_3$, $Fe_2O_3$ and CuO were below 0.4%, 0.3% and 0.9%, respectively. Principal component analysis(PCA) as a statistical method was carried out to classify glasses with the similarities of chemical concentrations. The result of PCA has shown that three groups of glasses were created according to the excavation positions and two major oxides(PbO and $SiO_2$) greatly contributed to the dispersion of glasses on principal component 1(PC1) axis and trace element oxides($Al_2O_3$ and $Fe_2O_3$) for PC2 axis. Most of lead glasses were greenish by the efficacy of iron and copper oxides and some showed yellowish-green. The gravity of lead glasses was about 4.4~5.4 and estimated melting point was near $670^{\circ}C$. Lead isotope ratios of glasses were analyzed and found quite close to a lead ore from the Bupyeong mine in Gyeonggi-do. Comparison with lead glasses found in Japan Lead glasses of Mireuksa Temple were compared with those of Japan on the basis of chemical and physical data. Chemical compositions of Japanese lead glasses dated $7^{th}{\sim}8^{th}$ century A.D. were nearly similar with those of Mireuksa Temple but lead isotope ratios of those were separated into two groups. Three distribution maps of lead ores of Korea, Japan and China with lead isotope ratios were applied for lead glasses found in Japan. The result have shown that the locations of lead glasses from Fukuoka Prefecture coincided with the region of northen part of Korea and similar with those of Mireuksa Temple and lead glasses from Nara Prefecture dated $8^{th}$ century A.D. were located in the region of Japanese lead ore. This research has demonstrated that lead glasses of Mireuksa Temple conveyed to Miyajidake site, Fukuoka Prefecture around $7^{th}$ century A.D. and glass melting pots and glass beads excavated from Nara Prefecture confirmed the first use of Japanese lead ore for production of lead glasses from the end of $7^{th}$ century A.D.

A well-bucket excavated from Seobu-dong, Kyungju was characterized and conserved. The bucket was heavily degraded by a diverse set of microorganisms during its long-term storage in the burial site. The distribution of maximum saturated moisture content was in the range of 614-1050%. The identification of species using optical microscope showed that the species was Pinus densiflora. The dimensional stability of the bucket was examined using sucrose as a dimension-stabilizing agent. The concentration of sucrose was started at 10% level and raised to 30, 50, 70% for 8 weeks. The changes of weight increase were varied with concentration. When the concentration of sucrose reached to 30%, 50%, the bucket showed the significant increase of weight, especially. Epoxy adhesives was used for the joining and restoring. Dimensional change and crack were not observed afterward.

Satellite imagery was applied to locating archeological sites and remains around northeastern areas of China, called as Manchuria, and Korean peninsular, such as Mountain Fortress of Goguryeo Dynasty era($37BC{\sim}771AD$), and firing torch and smoke beacon signal sites at mountain tops in Josun Dynasty era($1392{\sim}1910AD$) as well as burial sites below the ground level in the modern era. Information on archeological sites, fire posts and burial places could be found in various literatures, but real figures of such cultural assets have been disappearing due to land development programs and human activities in recent years. Some of these historical sites were identified in satellite images using GPS(Geographical Positioning System). Real locations of these sites would be further necessary to be verified.

Geophysical survey of Korea was introduced in Nara National Research Institute of Cultural Heritage in 1995. At that time, it has been activated geophysical survey of architecture and civil engineering in Korea. But there was no exploration experts to be combined the archaeology. For this reason, National Research Institute of Cultural Heritage has introduced the physical exploration. Through the expert exchanges South Korea and Japan carried out joint exploration. And it has increased the reliability of the exploration method and exploration results. It is GPR the most method commonly in geophysical exploration. There are many usability before excavation because of good resolution. However, the shallow GPR penetration depth has limitations in large mounds. We were able to take advantage of the resistivity analysis program to study the underground structure to deep through the experts exchange. We was able to get a good result that overcomes the limitations of GPR exploration in a number of burial mounds including Naju bokamri by the resistivity analysis program. In particular, we confirmed the location of the burial main body by compares the results of exploration and excavation results. In the future we will perform a convergence research of exploration and archaeology through a variety of joint research. In addition we will have to build a new network of archaeological science.

In February 1986, a high-school student reported the discovery of fragments of gilt-bronze burial goods on a mountainside behind a village in Ipjeom-ri, Ungpo-myeon in Iksan. The National Research Institute of Cultural Heritage immediately undertook an excavation. Unfortunately, gilt-bronze relics including a band and vertical decorations for a crown, a hat, and shoes had already been collected from Ipjeom-ri Tomb 1 by the student who found them before they could be properly excavated. Also, the interior of the stone chamber of the tomb had been severely disturbed by the time of excavation, making it difficult to identify the precise original locations of the relics within the tomb and hindering the reassembly of the fragments of the gilt-bronze crown. After conservation treatment, the gilt-bronze hat, shoes, and other relics were restored to their original forms and researchers were able to identify incised designs of a three-legged bonghwang(鳳凰), fish scales, lotus flowers, and other motifs. This study presents the major features of the fragments of gilt-bronze relics from Ipjeom-ri Tomb 1 and the methods of their production in order to provide basic material for their restoration and allow the eventual restoration of the giltbronze crown to its original condition.

Consumer interest in eco-friendly fashion products has been consistent. While most relevant research emphasizes individual morals and environmental concern as the most crucial determinants to eco-friendly consumption behavior, more recent studies point out that in so doing there has been somewhat a neglectance on the importance of fundamental marketing strategies. More specifically, the crucial role of interior colors in fashion retail stores has been managerially considered something certain yet no empirical results have been found to support such a strong managerial assumption. For instance, colors such as green, blue, and brown are believed to represent natural images and are more appropriate to the eco-friendly marketing and the relevant research has been lacking. Therefore, this study attempts to explore the effect of in-store interior design colors (green versus non-green) on consumer perception of green store images. A total of 382 respondents were gathered for an online survey using differing store images as the stimulus and used for testing hypotheses. In the results, respondents exposed to store images using green interior colors reported a higher evaluation of green store image of the store. The effect is found to be significantly moderated by respondent's environmental concern: to explain, respondents of high environmental concern are less influenced by green color interiors when they evaluate the brand's eco-friendly image. In sum, the positive influence of green interior colors on green store image is found statistically significant, with its stronger effect for consumers of low concern. Managerial and academic discussions are provided.

Electronic payment system using Internet banking is a very important application for users of e-commerce environment. With rapidly growing use of fintech applications, the risk and damage caused by malicious hacking or identity theft are getting significant. To prevent the damage, fraud detection system (FDS) calculates the risk of the electronic payment transactions using user profiles including types of goods, device status, user location, and so on. In this paper, we propose a new risk calculation method using relative location of users such as SSID of wireless LAN AP and MAC address. Those relative location information are more difficult to imitate or copy compared with conventional physical location information like nation, GPS coordinates, or IP address. The new method using relative location and cumulative user characteristics will enable stronger risk calculation function to FDS and thus give enhanced security to electronic payment systems.
