동굴의 유형 분류를 학술적 근거에 두지 않고 동굴 외부의 다양한 특성 즉, 숙박시설, 주변 관광지, 음식점수, 배후도시수를 변수를 이용하였다. 분석 기법으로는 군집분석을 이용하였다. 분석 결과 5개의 유형으로 분류되었으며, 이러한 결과는 관람객의 요구에 따른 다양한 분류가 가능하다는 결과를 말해준다.

본 연구는 일반인들에게 동굴의 다양한 정보를 제공하는 것이 목적이기 때문에 지금까지 행해졌던 학술적 분류법이 아닌 동굴 외부의 자료들을 이용하여 새로운 유형분류를 해 보고자 함이다. 최근의 관광은 관광지 한 곳 뿐만 아니라, 그 주변의 관광지들도 함께 관광하는 패키지 형태의 관광이 주를 이루고 있으며, 그것이 최근에 추세이기 때문에 동굴, 그 자체만이 아니라 주변의 환경도 매우 중요하다고 할 수 있다. 따라서 동굴 주변에 관한 변수들이 많을수록 관광객들에게 더 좋은 정보를 제공할 수 있으리라 생각한다.

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.

Caves can serve as major outposts for future human exploration of the Moon and Mars. In addition, caves can protect people and electronic equipment from external hazards such as cosmic ray radiation and meteorites impacts and serve as a shelter. Numerous pit craters have been discovered on the Moon and Mars and are potential entrances to caves; the principal topographic features of pit craters are their visible internal floors and pits with vertical walls. We have devised two topographical models for investigating the relationship between the topographical characteristics and the inner void of pit craters. One of our models is a concave floor void model and the other is a convex floor tube model. For each model, optical photographs have been obtained under conditions similar to those in which optical photographs have been acquired for craters on the Moon and Mars. Brightness profiles were analyzed for determining the profile patterns of the void pit craters. The profile patterns were compared to the brightness profiles of Martian pit craters, because no good-quality images of lunar pit craters were available. In future studies, the model profile patterns will be compared to those of lunar pit craters, and the proposed method will likely become useful for finding lunar caves and consequently for planning lunar bases for manned lunar expeditions.
