Different actinomycete strains were isolated from natural lime caves of Ondal Chemongok Hwanseon and Yongyeon which are located at Kangwon or chungcheongbook province in Korea and were identified to the genus level. Soil sam-ples were collected at 6 sites inside and 2 sites outside of each natural lime cave, As the result the strains belonging to genus Streptomyces and rare actinomycetes were isolated at the average of 2.1 and 3.4 strains per g soil on inside cave whereas which were isolated at the 6.0 and 1.8 strains per g soil on outside cave. How-ever the generic distribution of Streptomyces and rare actinomycetes isolated from outside cave was quite dif-ferent from that of inside cave. It was shown that rare actinomycetes at natural lime caves is generally highly abundant than Streptomyces.

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.

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.

Gossi-cave, which is Natural monument No. 219, originally was called Norigok-cave, but happened Imjin-Japanese war, aborigine and Gossi family took refuse to Norigok-cave. Japanese soldiers set fire to this cave, in result lots of people had been died. And then, this cave was called Gossi-cave because Gossi family only survived during the war. Stalactite, Stone pillar that was created from four hundred million ago Harmonized with the others. The length is 6.3km in 1969.6.4. this cave was appointed natural monument as a result of investigating Korean Speleological Society. Kim SaKat a Master Poet(1807-1863) : A Genius with wit and eccentric conduct, a poet who wrote a refined poems with his own dramatic path of life destructed the format of Chines poem and created a new folk literature. He is Kim SaKat - a wizard of poet Kim Sakat - a poet wearing conical bamboo hat. Kim Sakat was born in 1807, in the latter part of Chosun period, his antonym was Kim Byung-Yun. He passed the state examination in the first place when he was 20. Two years later, he set out his life as a wanderer when he realized his winning composition was a criticism on his grandfather.

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.

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.
