This thesis aims to examine when the petroglyphs of Cheonjeon-ri, Ulju were carved and their nature. To achieve this, the relations between rituals and rock carving motifs are examined besides the nature of the archaeological monuments with carved petroglyphs. The investigation revealed that the figurative motifs on the petroglyphs of Cheonjeon-ri, Ulju, may have been carved during the Korean Bronze Age considering other examples of figurative petroglyphs from that period. It is reasonable to assume that the figurative animal motifs on the petroglyphs of Cheonjeon-ri, Ulju were used for rituals of fertility and rebirth as a subsistence ritual during the Korean Bronze Age. The Geomdan-ri Archaeological Culture Type is a strong candidate, having used both petroglyphs of Cheonjeon-ri and those of Bangudae, Ulju, since the Geomdan-ri Archaeological Culture Type has a higher proportion of hunting and fishing and lower proportion of rice cultivation in its subsistence than in the subsistence of the Songguk-ri Archaeological Culture Type. In contrast to the figurative motifs, the abstractive motifs, including the geometric designs on the petroglyphs of Cheonjeon-ri, Ulju, are generally accepted to have been carved during the Bronze Age. Although there have been some disputes over the symbolic meanings of concentric motifs, lozenge motifs, and other geometric motifs, they may be related to rituals for sun worship, ancestor worship, and fertility cults. Their meanings have been continuously reinterpreted.

In this study, vegetation index, the vegetation index calculated based on hyperspectral images was used to monitor Petroglyphs of Cheonjeon-ri, Ulju from 2014 to 2020. To select suitable the vegetation index for monitoring, indoor analysis was performed, and considering the sensitivity to biocontamination, Normalized Difference Vegetation Index (NDVI) and Triangular Vegetation Index (TVI) were selected. As a result of monitoring using the selected vegetation index, NDVI increased from 2014 to 2018 and then decreased in 2020, after preservation treatment. On the other hand, TVI was difficult to confirm the tendency during the monitoring. This difference was due to the variation in spectral reflectance according to the photographing conditions by year. Therefore NDVI is less sensitive to spectral reflectance deviation than TVI, so it can be used for monitoring. In order for TVI to be used, however, in-depth study is needed.

Korean petroglyphs have been found over a lot of ruins through nation-wide regions including Daegok-ri Bangudae and Cheonjeon-ri in Ulsan. In this paper, we present an information system for Korean petroglyph ruins named KPetro which supports the dedicated camera application and the timeline service. The system provides the services for searching and updating information in various ways over the primary database constructed with the data on petroglyph ruins, which are collected by the Bangudae Petroglyph Institute. In addition, through the camera application developed for the system, users can easily add photos to the appropriate petroglyph ruin according to the GPS information of the location where those photos are taken. Also, the system provides the timeline service showing the photos for a specific petroglyph ruins in order of shooting time. To support both mobile and desktop environments, KPetro provides its functions in a web browser using the HTML5 standard technology and the JavaScript language, enabling the system to be adaptable to various user devices and extendable for its functionalities.
