Today, computer graphics have moved into spotlight within many related fields. The use of computer graphics in many fields as well as in design is now universalized. More than ever, those fields which utilize virtual reality are being vigorously researched and are rapidly progressing. Many advanced countries are obtaining positive results, allowing the world to learn about their culture and history by using virtual reality techniques for the restoration of cultural property. Above all, the West has utilized the diversity of the CAVE system which could best express the artificial system among virtual reality systems. However, in Korea this technology remains in its early stages of development. Moreover, the field, digital restoration of cultural property, which will be discussed in this study, hasn't yet been explored. Accordingly, this study presents the way of digitally restoring cultural property based on the CAVE through the empirical research and suggests the significance and possibility of digitally restoring cultural properly in the CAVE system. For them, this study processes the digitally restoring of Pulguksa Temple and Sokkuram and refers to the limitation and the future study following the investigation of CAVE and the introduction of applicable examples in abroad.

About 30 limestone caves have already been developed at the basin of the River Dong. baekyong Cave, Hwaam Cave, and Jeolgol Cave are of great worth, not noly as a matter of study, but as a matter of the tourist resources they develop. Among them Baekyong Cave is the best. I'm going to give a full detailed account of cave deposits and cave phenomena focused on its view to preserve the looks of Baekyong Cave by analyzing the speleothem of Baekyong Cave and cave system scientifically and systematizing them. Baekyong Cave, Natural Monument Ho. 260, is on the verge of being submerged. Peculiar things in Baekyong Cave are 1) pseudo stalgmite 2) anthodites 3) erratic stalagmites 4) cave shield 5) lost river 6) cave flint 7) pit fall but I have also mentioned general and related matters.

PURPOSES : The objective of this research is establishing system components and optimizing operational procedures in order to systematically manage road cave-ins in urban areas. METHODS : Based on the literature review and alternative comparison, optimization methods is suggested. RESULTS : Throughout the study, location referencing system, database structure, and operation strategy(procedure) were clarified, and the optimization methods for each item were suggested. CONCLUSIONS : Road cave-in management should be focused on user safety rather than focusing on economic aspects. The occurrence of road cave-in should be addressed thoroughly by road management system(location referencing system, database structure, and operation strategy(procedure), and the optimization methods), since they are closely related to road users' safety.

Immersive virtual reality provides an effective way of visualizing and analyzing various spatial data, such as wireline logs, three-dimensional seismic, and interpreted geologic boundaries, and etc. Although it is a valuable tool for oil and gas exploration, its usage has been limited to a specific area because of its high development costs. This paper describes the development of an immersive virtual reality system, known as CAVE (Cave Automatic Virtual Environment) that maximizes immersiveness with reasonable prices by using general purpose PC and projectors.

This paper is attempted to review a cave restoration and preservation plan against environmental destruction and pollution as a preliminary survey for preservation of cave environment. Consequently, it's important to throw an indirect light rather than direct light on cave formations, keeping distance of 2m at least. The already existing moss should be removed using wet cloth or sponge as soon as possible. If it's washed off, be careful not to splash it or water on nearby subjects. Based on an automatic switch-off system, light will automatically turn off when no one is left in the cave. It's also recommended to dualize the cave passage and partially close the cave by taking turns to give a time to recover.

The purpose of this paper is to analyze the implementation of the karst infrastructure systems for the u-cave. IT based u-cave represents spatial information derived fields, such as geographical distribution of the cave boundaries, physical configuration of the cave locations and formation characteristics of the karst history. These three aspects relate to karst infrastructure systems, cave monitoring center and spatial database implementation. In terms of the IT based u-cave infrastructure implementation systems, the u-cave depends on IT contents and spatial features. uIT contents are strongly related to IT839 strategy due to the national agenda is "u-Korea". Cave should contribute to u-cave construction through the spatial analyses methods including USN, RFID, LiDAR, ELD, and GIS technologies. For these methods various cave functions will guide to u-cave's distribution, location, and characteristics of karst. The infrastructure consists of landforms and speleothem facilities, underground related facilities, environmental protection systems, and cave planning. These six units of the cave infrastructures have spatial databases that consist of spatial configuration, such as 4-D in order to draw the spatial distribution of the limestone and lava caves. IT based u-cave system infrastructure implementation should deal with IT convergence to generate fusion affects.

Electroluminescent Display(ELD) will be the innovative ideas to replace existed electricity illumination systems that consider to under effectiveness and environmental pollution generators in the commercial caves because ELD has less heat and low electricity consumption by the new illumination materials. Characteristics of the ELD are as following: it is a proper matter for the small merchandise ads due to its thickness is only below 3oo micoron, electricity consumption of ELD is less (1/3) than LED, ELD that is a whole face illumination system is much brighter than LED that is a dot illumination system, ELD is longer life than others due to its less light generation systems, ELD is any problems to bend, and it is a best device to use a light board ads. ELD has advantages on conservation of cave biosystems and reduce pollution when ELD is installed in touring spots and emergency corridors of weak illuminated cave internal areas by less heating and low electricity consumption using the indirect illumination of the ELD. Therefore when the high technologic ELD is installed in the commercial caves in Korea, it will be innovating cave environmental systems, saving budgets, and increasing tours.

Recently, cave candidates have been discovered on other planets besides the Earth, such as the Moon and Mars. When we go to other planets, caves could be possible human habitats providing natural protection from cosmic threats. In this study, seven cave candidates have been found on Pavonis Mons and Ascraeus Mons in Tharsis Montes on Mars. The cave candidates were selected using the images of the Context Camera (CTX) on the Mars Reconnaissance Orbiter (MRO). The Context Camera could provide images with the high resolution of 6 meter per pixel. The diameter of the candidates ranges from 50 to 100m. Cushing et al. (2007) have analyzed the temperature change at daytime and nighttime using the Thermal Emission Imaging System (THEMIS) for the sites of potential cave candidates. Similarly, we have examined the temperature change at daytime and at nighttime for seven cave candidates using the method of Cushing et al. (2007). Among those, only one candidate showed a distinct temperature change. However, we cannot verify a cave based on the temperature change only and further study is required for the improvement of this method to identify caves more clearly.
