The problems of Ondal cave have been analyzed by the lack of academic names and explanations compared to other caves. To improve the problems, there needs to be various and balanced distribution of names, increase explanations, specializing in the form of academic explanations and the information format.

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.

The black pollution that was able to include green pollution to appear for the intensity of light by an illumination institution is what after all I cannot ignore, and it may be said that chase thing damage by the isolation action that is white pollution done a long story in this outside a certain range by air quality change, dried present situation is really the environmental disruption by development and a damage phenomenon. If I am replaced in winker and I install a sensor light in the outlet by addition and use the electricity illumination that I installed for a tourist in the cave, it is expected that I can be available all the time that it is possible for electricity reduction more than the present and watches tourist passage plan private business Electric illumination in the cave for the environmental save in the cave because it is possible for more electricity reduction to be particularly off-season than on-season.

The purpose of this paper work is to establish the plans of Gyeongju' identity through the activation of various culture tourism which for literature, narrative, experience and others in company with history tourism. And so first of all we are examined thoroughly the literature related to the characteristics of urban identity and the spot marketing in our country for establishing of this work. And then also we are carried out survey about the cases of Pyeongchang-gun where built around Hyo-seok Lee and Namwon where is too well known the tale of Chunhyang and then make surveyed the actual locale on Gongju and Buyeo in which the old capital of Baekjae. On the other hand the paper work are suggested the plans that Gyeongju' identity has been settled such as the historic culture tourism city of the various culture tourism programs by using of SWOT analysis.

The anatomy of the renal papilla and pelvis of the bat(Pipistrellus abramus abramus Temminck) and their ultrastructure of the epithelium has been studied by means of light, scanning and transmission electron microscopy. The bats were captured at Ondal cave located in Yangchun-Myun, Tanyang-Kun, Chungchongpuk-Do, Korea in the active(July) and hibernating(January) phases. A conical renal papilla with several papillary foramina at the apex was curved toward the ureter. At the margin of the funnel-shaped renal pelvis, the fornix extended deeply into the kidney parenchyme was formed between the outer zone of the medulla and the cortex. The epithelium of the papilla covered the inner zone of the medulla. The epithelium of the fornix medially overlayed the outer zone of the medulla, and laterally the cortex. The surface epithelium of the papilla was simple columnar in shape with the scanty organelles and the short microvilli on their luminal surface. The fornix was Jined with $1{\sim}2$ cell layered squamous epithelium. On the medial surface of the fornix, two types of the superficial epithelial cells were identified; one had numerous short microvilli and the other had the microplicae and plaques on their luminal surface. The lateral surface of the fornix lined with the epithelial cells showed microridges and plaques on the luminal surface. The epithelial cells on the medial and lateral surfaces of the fornix were similar to their internal ultrastructures. The pelvic epithelium was a typical transitional type, which was composed of a layer of basal cells, one or two layers of intermediate cells, and a layer of superficial(facet) cells. The fusiform vesicles were observed in the cytoplasm of the intermediate and facet cells. There were no noticeable morphological changes in the epithelium of the papilla, fornix and pelvis except the medial epithelium of the fornix in the hibernating cycle. The microvillar cells were more numerous in the hibernating phase than in the active phase. The morphology, of the renal papilla and fornix of bats, indicates that a functional relationship may exist between the pelvic urine and the renal parenchyme.
