This study is aimed to clarify the transitional characteristics of old roads and alleys lasting more than 100 years(1915-2015) in traditional urban area(Seongan-dong) of cheongju, historic inland and castle city of Korea. Cheongju castle had been completely destroyed In 1915, and urban structures been also altered last 100 years from 2015 now. Periodically, after destruction of castle, existing roads were extended and transformed to straight line for connecting with around. Expanding urban area to all directions of castle boundary in 1930-40s, town planning were created. These projects were completed in 1960-70s, the street network was built as they are. Since the 1980s, changes had been occurred in the details such as an extension of the unexecuted roads, the opening of fire lane in a block, and etc. In change and construction of roads, urban district plan in 1939 and reorganization since 1967 were planned and established with the type, location, and width of the large, medium and small roads based on data before destruction of castle. Except the width of 25m Sajikro(large3-1) and Sangdangro(large3-8,9,10), the width of 15m Namsaro(medium2-1) and Namjuro (medium2-4) as an extension of the roads, the other roads were small roads equivalent to the existing roads, and so remain intact figure of streetscape. As such, roads of east-west and north-south cross type, roads showing the outline of Cheongju castle fortress, and alleys outside the south gate are sustained in Seongan-dong of cheongju as historic urban area, and also present roads are delicately executed to the existing urban fabric.

The use of Hi-Tech in cultural heritage preservation and the promotion of cultural heritage values in general, particularly artifacts, opens new opportunities for attracting tourists while also posing a challenge due to the need to reward high-quality excursions to visitors historical and cultural values. Building Information Modeling (BIM) and Hi-Tech in new building management have been widely adopted in the construction industry; however, Historic Building Information Modeling (HBIM) is an exciting challenge in 3D modeling and building management. For those reasons, the Scan-to-HBIM approach involves generating an HBIM model for existing buildings from the point cloud data collected by Terrestrial 3D Laser Scanner integrated with Virtual Reality (VR), Augmented Reality (AR), contributes to spatial historic sites simulation for virtual experiences. Therefore, this study aims to (1) generate the application of Virtual Reality, Augmented Reality to Historic Building Information Modeling - based workflows in a case study which is a monument in the city; (2) evaluate the application of these technologies to improve awareness of visitors related to the promotion of historical values by surveying the experience before and after using this application. The findings shed light on the barriers that prevent users from utilizing technologies and problem-solving solutions. According to the survey results, after experiencing virtual tours through applications and video explanations, participant's perception of the case study improved. When combined with emerging Hi-Tech and immersive interactive games, the Historic Building Information Modeling helps increase information transmission to improve visitor awareness and promote heritage values.

충청지역의 다양한 유적의 소토(燒土)에서 구한 34점의 고고지자기 측정데이터를 통해 충청지역의 고고지자기 변동 양상을 살펴보고, 더 나아가 국내에서의 지자기의 지역적인 차이에 대해 검토해 보았다. 충청지역의 고고지자기 측정데이터는 거리상으로 차이가 있는 일본의 고고지자기 변동과의 비교에서 보면, 전체적인 변동 모습은 비슷하나 A.D. 300년경에서는 편각이 동쪽으로 10도 이상 치우치는 현저한 차이를 보이고, 그 이외 시기에서는 복각이 다소 깊어지고 편각이 서쪽으로 약간씩 치우치는 지자기의 지역적인 차이가 확인되었다. 이러한 양상은 우리나라 전체의 고고지자기 변동 양상과 큰 차이가 없으며, 충청지역 데이터와의 직접 비교에서도 국내에서는 서력기원전시기와 기원후 시기 모두 뚜렷한 지자기의 지역차는 확인되지 않았다. 앞으로 더 많은 고고지자기 측정 데이터가 증가하고 다양한 시기의 데이터가 채워지면 더욱 명확해 지겠지만, 충청지역 유적의 고고지자기 측정결과를 통해 볼 때, 지자기의 지역적인 차이에 의해 발생하는 고고지자기 측정연대의 오차와 같은 문제점은 우리나라 내에서는 크게 걱정하지 않아도 될 듯하다. 게다가 시료의 채취와 측정에서 신뢰가 가능한 측정데이터를 구하기 위하여 많은 노력들을 하고 있기 때문에, 고고지자기 측정결과에서 추정연대의 오차문제 뿐만 아니라 데이터의 신뢰도의 측면에서도 문제가 없을 것이라 생각된다.

It is important to accurately predict structural responses to external excitations such as typhoons and earthquakes when designing structures for serviceability. One of the key procedures to predict reliable vibration responses is to evaluate accurate structural dynamic properties using finite element (FE) models, which properly represent the realistic behavior of buildings. In the case of historic masonry buildings, structural damage could also be caused by ambient vibrations or impacts. Therefore, the preservation plans of historic buildings for low-level vibrations or impacts should be provided by analyzing structural damages within serviceability levels. For this purpose, it is required to provide FE model construction and response analysis methods verified with field measurement data. In this research, long-term field measurement was performed for a cathedral and its dynamic properties were evaluated using measured data. Then, the model was calibrated based on the measured dynamic properties and an overall construction method for the masonry cathedral was proposed. Using the measured accelerations, the vibrations of the belfry were analyzed using the calibrated FE model and finally, the FE model for the cathedral was verified by comparing the measured accelerations with the modeled results.

Despite its ecological importance of wetlands in our life, wetlands around cities and villages have been steadily disappearing. It is mainly due to either natural geological changes or man-made causes such as permitted land zone changes for the purpose to convert to agriculture land. This study aims to establish a comprehensive database of wetlands using GIS in a historic conservation city Gongju City. The systemic data management would enable to identify distribution of wetlands and their ecological attributes, and to estimate the conservation value of the wetlands. The data base will be able to use in strategic way to preserve the local ecological areas for local residents and tourists and manage the quality of wetlands in the historic and conservation city. For the purpose, it is suggested organising a wider network with not only local residents but local authorities and relevant stakeholders would be beneficial. This study also recommends that long-term strategic plan to preserve the existing wetlands. This study findings as a seminal case example can be used to apply to other geographical areas of the country and can contribute to create a national ecological nature map as well as evaluate the attributes and quality of natural ecosystem service of the region.
