Abstract3D scandata have become increasingly popular for the preparation of survey drawings in wooden architectural heritage. The objective of this study was to identify the pros and cons and characteristics of 3D scandata. Along with survey record sheets and photographs, 3D scandata are raw survey data that are produced directly on-site. These raw survey data are then further processed in an office in order to be used as survey drawings.Among those three items, 3D scandata most notably convey the overall shape, location, and dimension of the heritage, while also providing accurate measurements allowing for more accurate survey drawings. However, 3D scandata are somewhat limited in that they do not provide certain information such as colors, materials, and coupling schemes. 3D scandata are obtained in the field, but are usually processed and screened in an office. Some of the 3D scandata are selected to make survey drawings. Therefore, they can serve as useful complements to other types of raw survey data. Furthermore, 3D scandata are beneficial to the tracing of changes in structures, and can also be used for maintenance management and the development of BIMs.In essence, surveyors are required to perform 3D scanning, as 3D scandata can enhance the accuracy of survey drawings and are utilizable in other valuable ways.

This study investigates the sustainable values of cafes established using idle industrial facilities that are a part of the cultural heritage of South Korea in terms of the characteristics of the architectural space and consumers’ space utilization. Twenty regenerative cafes in five regions were selected, and five of them were analyzed by comparing their characteristics with those of the conventional cafes. Unlike conventional cafes, regenerative cafes have architectural spaces that seem to be non-everyday and elicit a feeling of the passage of time. Users utilized these cafes as spaces for activities and experiences for long periods compared to conventional cafes. Consequently, regenerative cafes were found to contain sustainable values as complex networking spaces, as cultural heritage that can be experienced and as independent tourist destinations. Regenerative cafes have become unique differentiated architectural spaces utilized by several users.

This paper examines 41 roadside commercial buildings of the Jongno region built in the 1950s–60s that received façade renovations between 2001 and 2017. The aim is to show the relations between the forms of renovation and the regionality of the commercial areas, which have been historically formed in the original city center of Seoul, as well as the relation of these connections to the sustainability of ordinary architecture. Because Jongno has been the city center for the 600 years following the Joseon dynasty, the region is still a center for politics, administration, economics, and culture. Specialized commercial areas exist in each region within Jongno, and each of these reflect their own regionality. Within such regionality, the roadside commercial buildings are adapting and changing to fit the times, and regionality is sustained through façade renovation of ordinary architecture. The façade renovations of roadside commercial buildings that reflect such regionality and sustainability do not involve redevelopment through overall demolition, which represents a loss of regionality and history and is conducted undemocratically; rather, the practice should be acknowledged for adding value as past heritage and the simultaneous incorporation of present and future values.

Column leaning in Korean traditional wooden heritage structures has been emphasized in various reports since the first survey report in the 1950s, which established the importance of its measurement. Manual measurements have been carried out for a long time; however, recently, three-dimensional (3D) scanning has been used to obtain accurate data. Through periodic surveys of column leaning using 3D scanning, column displacement can be measured accurately.This study aims to measure the column leaning in Sungryeoljeon at Namhansanseong, a World Heritage Site, using 3D scanning, and then determine its displacement through a periodic survey. Such displacement in column leaning may reveal the characteristics of wooden architecture.The 12 columns of Sungryeoljeon are displaced in different directions. Generally, they lean toward the south and rotate clockwise. Column displacement does not occur so quickly in certain directions. Nonetheless, the aspects of column leaning that are already in progress need to be observed carefully.

This study considered that the pursuit of nature in a city in the restoration projects of Cheonggye Stream and Suseongdong valley was the main motive of the landscape concept premised on humanity and, furthermore, found that it originated from Korean thoughts and cultures about nature. Based on these findings, the study aimed to investigate the influence and sustainability of historical and cultural backgrounds in the planning features of nature in the two restoration projects. The concept of landscape that started from the desire to go out of a city is premised on the secular world of humans. In Korean society, the concept has been developed based on the above common premise, through cultural exchanges with China, and in its regional specificity. In particular, the Korean culture of singing and painting the beauty of landscape using the words “Gyeong (景)” and “Gok (曲)” can be found in the backgrounds and landscape architecture plans of the Cheonggye Stream and Suseongdong Valley restoration projects. Therefore, the historical and cultural thoughts that pursued natural beauty were in the work for the restoration of the two streams, and these concepts should be considered for sustainable development for harmony between the city with nature and between nature with cultures.
