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.

The research of caves widely deals with geomorphology, meteology, geology, biology, archaeology and physiochemistry. Most famous caves in Korea are in Dongrong Cave in Yongbyun-Goon in 1929, Sungru Cave in Uljin in 1960s. Lava caves were developed as Gymrung Sa Cave, Manjang Cave and Hupje Cave in Cheju Island. Limestone caves, Gosi Cave, Gosu Cave, Nodong Cave and Chundong Cave, were developed for the commercial purposes. Visiting and researching caves are active in Korea. Caves will more be commercialized than before.(omitted)

Yangdan Cave displays as a Vadose Cave rathre than a Phreatic Cave due to its fluvial activated ramnants of the cave beds and walls. Geochemistry experiments of the speleothem (stalactite and stalagmite)were generated in order to find out the cave material characteristics using XRD. The results present that the composition of the cave materials consists of Calcite, Dolomite, Quartz, K, K-Feldspar. Plagioclasc, Illite, and Kaolinite. These materials commonly exhibited less mineral composition than other caves. In terms of calcite compostion of the cave the upper cave materials (d=3.049) contain less than lower cave materials (d=3.055). Finally the calcite compostion of the cave materials between stalactite (d=3.055) and stalagmite (d=3.054) displays simillar values.

The examination of sediment distribution in Seongryu Cave shows existence of rocks contrasting with Joseon Supergroup contrary to existing knowledge. Contrasting especially with the Taeback Group, Daegi Formation, Hwajeol Formation, and Dongjeom Formation has been observed. Unlike Taeback area where Dumugol Formation and Makgol Formation are observed on top of Dongjeom Formation, the rocks of this area are not clear in its separation between the two, so that it was named Geunnam Formation. Seongryu Cave has been developed in this Ordovician Geunnam Formation of the Joseon Supergroup. The cave, mostly horizontal, runs in the NE-SW direction, and contains three lakes. The main passage and branches are about 330 m and 540 m, respectively, making the total length of the cave about 870 m (show cave area = 270 m). Through underwater examination, about 85 m-long underwater passage was newly discovered. Various speleothem such as soda straw, stalactite, stalagmite, column, flowstone, rimston, cave shield, cave coral, curtain, bacon sheet, cave pearl, cave flower, helictite and calcite raft can be found in the cave. There are sections with constant flow of cavern water, but the majority of cavern water in the cave come from the ceiling. The most important discovery in this study is the presence of various speleothem in the submerged part of cave passages. Traces of corrosion and/or erosion can be observed in the speleothem in the submerge passage.

Recently many environmental researcher are concerned about the ecological environment and the issue of environmental pollution in cave. In this paper we discuss about air pollution, water pollution, state of water quality, ecological environment and situation of environmental public damage in cave The concerning of air pollution in cave is mainly to the type of secondary contamination, which much is developed in various fields recently. The natural water in the most of cave is no problems but ground water has slitting with natural water during much raining period. The state of water quality is gradually contaminated with artificial environmental pollution, that is, the contents of kinds of Aluminum, Nickel, Copper, Zinc and Calcium are higher than before. On the other hand it is very important things to keep the control of constant temperature, darkness and humidity in cave. The contamination by lamp flora and even black colored contamination are appeared nowadays. The ecological environment in cave destructed by growing of mi coorganism. In fact the internal of cave is shielded with the state of climate of cave external but the environment of internal cave is contaminated, because blowing from external climate state. In addition to environmental pollution caused by carbon dioxide and body temperature of tourists. By the way eco-examination of cave is black color public damage, green color one and white color one has been discovered, so we need to have the situation of demand of environmental reservation alternatives.

Seongnyu Cave have developed along the NE-SW direction in carbonate rocks of the Joseon Supergroup. The cave mostly shows horizontal passages and contains three lakes. The main passage is about 330 m long with 540 m-long branches, thus the total length of the cave is about 870 m. Through cave diving, about 85 m-long new passages were discovered. Numerous speleothems such as soda straws, stalactites, stalagmites, columns, flowstones, rimstones, cave shields, cave corals, curtains (and bacon sheets), cave pearls, cave flowers, helictites and calcite rafts can be found in the cave. Especially, some speleothems which were believed to have grown in the past were discovered in the submerged passage, and a few stalactites, stalagmites, flowstones and columns were eroded (or corroded) by the cave stream that flowed on the floor. Because these speleothems only grow in subaerial environments within limestone caves, it appears that they grew when there was no lake in the cave and became submerged as the lake level rose in the cave. The presence of these speleothems in the lakes indicate that they only grew during glacial periods when sea-level was lower. Therefore, detailed investigation of these speleothems will provide invaluable information on paleoclimatic evolution around the Korean peninsula in the future.

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.

After the opening of Gosu - cave, as tourist has increased, the inner parts and outer regions of cave is changed. This paper focuses on the environmental changes according to development of tourist resort in Gosu-cave. The result of this study can be found in the following facts: (1) As cave is opened lighting equipments set up for the purpose of helping inspection and coming in and out. (2) As the temperature rises in the coming in and out of tourist, this is caused to dry and peel off the topographes in cave. (3) The quality of water in cave is contaminated by the wastes, garbages and coins by tourists. (4) As Chungju - Dam has constructed, the linkages of the other tourist resort of Gosu - cave is improved. It is raised on the accessability of Gosu - cave. (5) As people has access to Gosu - cave, tourists increased more than the former times. Thus this phenomenon is contributed to the increasements of regional incomes and opportunity of regional employment.
