This study was conducted in order to evaluate the characteristics of air temperature fluctuation inside the Daegeumgul, Ondaldonggul, and Seongnyugul Caves, which are the most representative limestone caves in Korea, and also to assess the effects of air temperature on cave temperature. Temperature was measured hourly at three sites in Daegeumgul, Ondaldonggul, and Seongnyugul Caves from April 13 to June 25, 2019. Additionally, air temperature data for the areas around the caves was provided by the Meteorological Administration. Using this collected data, the basic statistical measure of fluctuation characteristics over time was ascertained, and time series analyses were performed. Wide variation of temperature was exhibited in the order of the cave entrance, the cave water inflow point, and the midpoint. Cave temperature was observed to increase gradually during the study period. There was a vast range in temperature at the Daegeumgul station located approximately 150 m outside the cave, but it remained nearly constant beyond the midpoint. Although the effect of air temperature was not significant due to the influence of visitors, the effect of air temperature on cave temperature gradually decreased from the entrance to the interior. At Ondaldonggul, there was a wide range in temperature recorded at the entrance due to the influence of air temperature, but it stayed almost constant in the interior. However, at the site where cave water flows into the cave, temperature was influenced by the cave water temperature. At Seongnyugul, there was a distinct fluctuation in temperature recorded at the cave entrance, while the middle of the cave remained nearly constant. Temperature fluctuated due to the air temperature at the entrance, while at the middle of the cave, measurements were expected to be affected to a greater extent by the lake water temperature than by the air temperature. However, this pattern was not observed. According to the time series analysis results, in all caves, fluctuations of air temperature affected cave temperature after approximately one hour. Cave size and structure, water presence, the entrance's size and shape, air flow, and visitor patterns can all influence cave temperature. Therefore, consideration of these factors is very important in the pursuit to clearly understand cave temperature characteristics.

The guano formed from the bat excrement in a cave contains various sulfate and phosphate minerals formed from the reaction of bat excrement with surrounding rocks and clastic minerals. Therefore, the mineral compositions in the guano provide basic informations on the geochemical environments affecting mineral formation in a cave. This study was conducted to study the mineral compositions of guano and the factors affecting those compositions by comparing mineralogical and chemical compositions in three different limestone caves in Korea. The guano samples in Gossi Cave contain detrital minerals such as illite, quartz and feldspar and relatively large amount of gypsum. The contents of gypsum increase with increasing depth, which is different from the samples collected in other caves. The samples collected from Baekryong Cave have the similar mineral compositions to those in Gossi Cave, but they also contain additional kaolinite and very small amount of gypsum. The samples in Sungryu Cave have similar mineralogical compositions to those in Gossi Cave, but contian bassanite instead of gypsum. The mineralogical compositions are well correlated with the chemical compositions of guano. The mineral compositions indicate that, in Gossi Cave, the minerals were formed by the reaction of large amount of bat excrement with surrounding rocks in high humidity condition or in the condition of frequent floods. In the case of Sungryu Cave, bassanite which can be formed in a dry condition indicates that minerals were formed in a relatively low humidity condition.

Many researcher contended that the tourism types of modern society has changed to 'experience tourism' from 'seeing tourism' recently. Therefore attempts to add edutainment factors in the original tour program has been introduced in cases of tourism cave. As we can see the Hwaam-cave in Jungsun-gun, by preparing with various pavilions which are well-matched with tourism cave. So, the purpose of this study is to the presentations of the activation programs that having on characteristics of edutainment tourism resources for tourism cave. Thus, first of all for establishing of this study, we examined the characteristics and values as tourism resources of cave and then observed the roles and examples of edutainment tourism cave, finally suggested the activation programs that can be shaped for edutainment tourism of cave.

Since the existing cave type classification has no variety but was limited to the structural, genetical and dimensional classification, we need the new cave type classification. When we analyze the theoretical background of cluster analysis, the cave type can be classified in consideration of diverse variables depending on the selection of variables to use and the usability of such classification is very high. With the practical consideration on the internal environment of cave and surrounding environment, three classifications are available; first, numerical classification by the dimension and form of cave; second, classification by the use of land out of the cave and geographic features; third, classification by the feature of location related to the surrounding areas of cave.

The Buddhist cave temple carved into the rock provides a large space for the ritual in general in which a structure of Stupa is built in the center of the space purely for religious worship empty of Sarira, and the temple is formed around this Stupa. Relief-Stupa of the cave temple indicates the similar shape that of Relief-religious worship of flat land temple. However, there appears a small difference in representation since the background of formation of the cave temple differs in that of flat land temple. Specially, Caitya Stupa of currently existing cave temples have been damaged to lose of their original shape only possible to be analyzed the stylistic development through Relief-Stupa from which the characteristic of Stupa could be understood. The early cave temple could be characterized with a balanced structure consists of upturn bowl, steeple stone with simple drum & Hamikawasnagae, in which it appears strongly the detail factor characteristics of drum & steeple of having system with Caitya Stupa. In the post cave temple, the subject of worship moved to statue of Buddha due to the influence of Gandhara, Mathura art which reduced the importance of Stupa. This illustrates in Relief-stupa as well the style change as well as changes in detail factor. The sculpture appeared at the limited location either the wall of Caitya shrine or pillar in vihara cave with stronger decorative meaning. Contrast to the Relief Stupa of early flat land temples or the cave temples mentioned above sculptured with symbolism, however, the post cave temple showed the relief structure based on the plan of flat plan.

The Gossi Cave, Natural Monument 219, extends horizontally for 3,388m with 215m elevation. 620m of the horizontal cave length was opened to the public in 1974. The Gosu Cave, Natural Monument 256, also was opened the public for only 685m of the horizontal cave length, 1,700m, in 1976 in order to preserve its ecological cave environment. The surface of the speleothems in two caves have been turning black due to pollutants after the caves were opened to the public. The degrees of temperature, humidity and partial pressure of carbon dioxide in the caves were related the seasonal variation. Specially, the value of partial pressure of carbon dioxide($CO_2$) in the cave higher in the summer than any other seasons. The partial pressure of $CO_2$ continues to build in the summer because of exceed the self-purification limit in the caves. The value of $CO_2$ variation in the caves was mainly controlled by the amount of visitors. As a result, we have to controlled the amount of visitors to preserve the cave environment.

The Wooro cave speleothem displays comparatively very less developed characteristics due to its unactive fluviation, less soluable carbonate rocks, 3nd disconnected short voids. The Weoro cave consists of stalactite, stalagmite, flowstone, rimstone, and moonmilk, however, it is not exhibite soda straw, cave pearl, pisolites, curtain, drapery, cave flower, anthodite, cave coral, helictite. heligmite, boxwork, pendent and, cemented shield. The main cause of the underdevelopment speleothem of the Wooro cave probably less peneturated waters or less calcite compostion of the carbonate rocks.

Ever since the beginning of time, caves not only have offered a place to live for humans but they have also been used as cultural spaces. That is, in the event of making some sounds in a location within the cave, the sound that is created is greatly magnified and sounds out as if it is being amplified from a giant megaphone. This, as we well know it, is known as the resonance effect. Here, the cave itself appears to function as a massive wind instrument. Especially in cases like the Altamira Cave (Spain) where cave paintings were found, the point where the cave drawings were found has commonalities in that it is a wide space and that it is usually discovered together with flutes and drums that are made with mammoth bones. We need to focus on this point. We can infer from these facts that the prehistoric people have carried out cultural activities along with their incantation rituals within those caves. In the meantime, amongst the Korean traditional arts, in the case of pansori which is a representative vocal genre, there have been examples where caves were used as practicing locations for those people who are training to perfect their singing. This is known as toguldoggong(土窟獨功) which literally means 'obtaining one's own art by oneself in the earth cave by practicing incessantly'. This process along with pokpodoggong (瀑布獨功) (same as above except that the location is by the waterfall) is the final training stage in order to become a recognized virtuoso on the part of the apprentice. This could be compared to the final annealing and finishing process of producing a metalwork. This has been a long tradition followed by most Korean traditional artists in order to perfect their sound which is harmonious with nature within natural surroundings. By honing in on this point, I have come to think about this matter repeatedly while coaching the university students in vocal singing. In short, I came to the conclusion that "the making of natural sounds will be obtained naturally within natural surroundings like caves!" Consequently, The Society for Studying Cave Sounds was inaugurated on January 1992 along with some of my students. We made use of times like vacations to go around exploring caves all over Jeju and carried out investigations of sounds along with cave exploration on an experimental basis. After 5 years, in September of 1997, we were able to host the first ever cave concert domestically at the Whale Nostril Cave(東岸鯨窟) on Wu-do. After that, we have been hosting the cave concert once every year. We have achieved a record of a total of 14 cave concerts until 2009 of this year. Out of these, 2 were held in Seokhwaeam Cave in Kangwon Province, another two were held in Manjang Cave which is a lava cave, and the remaining 10 were held in the Whale Nostril Cave of Wu-do. Along with that, I have carried out a special recording for the production of a cave music CD in May of 1999. This paper was written and organized by using the main materials that were derived from the experiences of using caves as concert halls in the past. It is hoped that this cave concert will offer a very unique experience to tourists who come to Jeju every year and give them the best possible superior natural sound effect that only Jeju caves can offer.
