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.

Archaeological survey has been carried out to find some evidence of human occupation in 31 caves in Pyeoungchang, Danyang, Jincheon, Goesan, Munkyoung, Boeun, Sangju in central limestone area of the Korean peninsula. Among those caves, some archaeological evidences were observed in 11 caves. Various types of potteries, animal bones and stone artifacts were collected on surface of sediments in caves. Among them, the Mosan cave in Munkyoung and the Kwangcheonseongul in Pyeoungchang are very likely to yield important archaeological remains in the well preserved deposits in the caves. Further researches are expected to provide significant information for explaining human living from prehistoric time to historical periods.

To find out the natural environmental characteristics of Ondal Cave, temperature, humidity, wind speed and water temperature have been investigated. When compared to other caves, in sum, Ondal Cave has shown no significant difference interms of natural environment. Inparticular, Ondal Cave was higher than other limestone caves by 1-2$^{\circ}C$ in terms of water temperature due to high inflow of river water nearby.

In an early stage, a study on speleologyand cave environment was very active even though the number of papers was limited. From the mid 1980s to 2000, the academic activities on caves were the most active with a variety of subjects. Since the 1990s, people started to focus on the environmental change in caves and preservation rather than development. Recently, many studies have dealt with humanistic environment, seeing caves as a tourism resource. Therefore, the correlation between the cave and surrounding tourist destinations has been actively studied.

In Korea, only a few cave spiders have so far reported, so little is known as their fauna. The author investigated on the caves, various part of this country to have taken up the study of these spiders, detailed report will be made in future, but for the present, has dealt with as follow; 1) As a result of the historical review of the study on cave spiders have been recorded 39 species of 27 genera belonging to 15 families, including 16 new species in Korea. 2) It were recorded that the name and location of 154 caves; 121 limeston caves, 33 lava caves which surveyed by the author. 3) A list of cave spiders made out about 100 species 60 genera belonging to 23 families. However there are considerable number of species which have not yet been identified and waiting for descriptions particularly in the troglobiontic species. Especially the Leptonetid, Nesticid and Cybaeid species are very important matrials for discussing the variatoin and lineage of species through isolation. 4) Species common to foreign countries are restricted to a few; 25 species of Japan, 2 species of Europe. There are not exist troglobiontic species, and most of them are trogloxenous ones.

BACKGROUND: The Geomunoreum Lava Tube System (GLTS) is both vast and culturally valuable. The Jeju Volcanic Island and Lava Tubes, which are partly composed of the GLTS, have been declared as a United Nations Educational, Scientific, and Cultural Organization (UNESCO) World Heritage Site. Exploration of the caves is strictly regulated to conserve these vulnerable environments. Photographs provide limited information and do not describe the entire environment comprehensively. Therefore, we created several illustrations of the lava tubes to display their environmental features. METHODS AND RESULTS: We explored six lava caves (upstream and downstream) in the GLTS and photographed their geological features and yellow walls, the colors of which are influenced by microbial mats. We compared the hex codes of the wall colors using the Clip Studio v1.10.5 software and created illustrations that accurately represent the scale and features of the caves. CONCLUSION(S): Upstream and downstream caves of the GLTS differ in scale and volcanic features. We illustrated various characteristics of the caves including lava cave features, vegetation, and microbial mats. We also described the internal and external cave environments.

Five species of Tomoceridae from Korean caves are reviewed , including one speices described as new to science. T. (M.) odongnyeoensis n.sp. belong to the subgenus of new record for Korea. The present study eventually resulted in listing eight species in five subgenera of Korea cave Tomoceridae, and all Collebola from Korean caves nowenumerate 23 species (or subspecies) in nine genera of eight families.

Unlike conventional cave classification, this paper is attempted to classify caves in Korea in considerations for the surroundings. As a result, it‘s been confirmed that a cave can maximize the effect of information delivery as a part of great tourism resources. It‘s also been confirmed that the characteristics of caves can be differently interpreted depending on the size of surrounding humanistic environment as well as the size of the cave.

Limestone caves that consist of main passages and branches are formed by a variety of processes, and have the characteristic of developing with a preferred orientation controlled by discontinuities such as bedding, joints, and faults around the cave. However, it is difficult to analyze a representative orientation from various orientations. To interpret the overall development orientation of limestone caves, this study proposes new development orientation analysis methods, termed the Average Span Ratio Method (ASRM) and the Individual Development Ratio Method (IDRM), using the weighting of persistence. Nine limestone caves in Korea were randomly selected for testing the new methods. The methods show a stronger development orientation for limestone caves than that obtained by traditional methods, which consider only the distribution of development orientations. Based on an analysis of the relationship between the average span and the dip angle of bedding, it is confirmed that shallowly dipping bedding is a major contributor to the expansion of span in limestone caves. In addition, using scan-line survey data acquired in the field, we perform an RMR analysis of stability of the ground around limestone caves.

This study is about the efficiency of graph theory that can be applied as the research analysis method in order to identify the relational location features of the caves favored as the ecological tourists attraction. Creating network with traffic nodes and surrounding tourists attractions in a certain space including the caves as the tourists attraction and structural analysis on the overall network using various kinds of index will be very useful method to identify the relational location features and benefits from linking the caves as the tourists attractions. In particular, it can be applied to set the spatial scope in the tourism development plan including the caves as the tourists attractions.
