In the cave, there are three kinds of CO2 gas from the human body and humidity or H2O from the underground water and also light from illumination fixture creating plants by photosynthesis. For this reason, the green plants of moss created and lived on the rock in the cave, but sometimes there would be the dry season to be killed the green mosses and hence, it could be dried and blackish. When the dried mosses were taken off from the surface of the rock like as laminated dried one, the moss lamination could be taken off together with the skin of the formated stalactite in the cave. Therefore, cave environment should be changed and degenerated. So it is useful and necessary to get selective wave lighting to have photosynthesis in the cave or not to have it in there by using of the LED lamps.

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.

Cave 79 of Kumtura grottoes, is the best preserved cave, which has an important meaning for research on Uighur costume. This paper is intended to analyze the costume characteristics of female donors in Cave 79 by comparing image materials between Dunhuang murals and other murals in Xinjiang province. In Cave 79, female donor wears red robe with tight sleeve, whose collar is crescent-shaped decorated. Two different opinions are upheld for this decoration. One regards this as the turn-down collar, while the other believes this as decoration on V-neckline. Red robe is quite common in female donors of Xinjiang and Dunhuang murals and a female in fresco is wearing a crown in a triangle red headwear style, regarded as red silk and drooping at head. Female donors wear an extra coat, kame hair clasp, red jacket, light-colored high-waist skirt with a long-tail waistband, and tangerine Pibo (silk ribbon) with scattered small flowers. All these costume styles are commonly-used by Han females. The kame headwear is also the common ornament for Han females and the female's hairstyle is in cone shape on head by a white kame. Current costumes are similar but not completely same.

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.

CAVE 시스템은 다수의 프로젝션 장비들을 사용하여, 물리적으로 사용자를 둘러싼 각 면에 영상을 투사하여 사용자에게 현실감을 제공하는 통합환경이다. 본 논문은 CAVE 시스템을 실제 구축하여 보고, 시스템을 구축하는데 있어 문제가 되는 각 면에서의 영상의 초기 설정의 보정 문제, 다수의 영상이 사용자의 시점에서 왜곡되지 않고 현실화되도록 하는 알고리즘과, 사용자의 시점을 찾기 위한 위치 추적 장비의 정확성 문제와 시점에 대한 보정 문제, 사용자가 가상 공간을 운용할수 있도록 하는 장비들의 사용 환경 설계 문제 등을 해결하는 방법에 대하여 연구하였다. 또한, 본 논문은 CAVE 시스템 안에서 각 장비들이 전체적으로 조율 되어 운용되는 방법을 제시한다.

Cave survey is close relate to the culture and environment of the Area. And the Korean culture and the skeleton of the spirits are very similar to that of continent. in this paper some caves are studied and find the close relationship between the present culture and the past cultures.

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.

By providing an environment where energetic particles and micrometeorites can not penetrate, caves on Mars may serve as a human shelter in future Mars explorations. More than 1,000 cave entrance candidates have been detected; however, their physical characteristics that can be utilized in detecting more candidates have not been explored in detail. In this paper, we explore the nighttime temperature of 100 cave entrance candidates and their surrounding areas to investigate 1) the nighttime temperature tendencies relative to their surrounding areas and 2) the extent of these temperature differences. We find that 79% of the cave entrance candidates exhibit higher temperatures than the surrounding areas, and 59% show a temperature difference over 20K, suggesting that the cave entrances may generally show higher temperatures than the surrounding areas during the nighttime.

(1) The author surveyed the environmental factors and the fauna of Sung-Yoo Cave(360m in length) from November 29 to December 2, 1961. (2) Air temperature, water temperature, moisture, water depth, water gravity, oxygen concentration carbon dioxide concentration and pH in water of the cave were studied as enveronmental factors. The results are shown in the Table 1~7 and Fig.3. (3) Four species of troglobite (22.2%). seven of troglophile(38.9%). four of troglozene(22.2%). and three of parasite constitute the terrestrial fauna of Sung-yoo Cave. In the other hand, all of the aquatic fauna(4 species of fish) of the cave were troglozene. (5) None of the species of animals listed in this paper has ever been recorded in Korea.
