After the opening of Gosu - cave, as tourist has increased, the inner parts and outer regions of cave is changed. This paper focuses on the environmental changes according to development of tourist resort in Gosu-cave. The result of this study can be found in the following facts: (1) As cave is opened lighting equipments set up for the purpose of helping inspection and coming in and out. (2) As the temperature rises in the coming in and out of tourist, this is caused to dry and peel off the topographes in cave. (3) The quality of water in cave is contaminated by the wastes, garbages and coins by tourists. (4) As Chungju - Dam has constructed, the linkages of the other tourist resort of Gosu - cave is improved. It is raised on the accessability of Gosu - cave. (5) As people has access to Gosu - cave, tourists increased more than the former times. Thus this phenomenon is contributed to the increasements of regional incomes and opportunity of regional employment.

Gosu Karst Cave 지역은 우리나라에서도 Karst rocks가 가장 잘 발달된 곳이며 특히 이 지역은 고생대의 조선계 대석회암통에 해당된다. Karst Cave와 여러가지 형태의 생성물은 지질시대부터 생성에 알맞는 고기후학적인 조건과 지구화학적인 여건이 결합하여 풍화작용의 결과로 이루어진 것이다. Cave의 발달 방향은 지층의 주향과 거의 일치하며 지금도 이러한 형성작용은 진행되고 있다. Cave 내부의 기후환경의 영향으로 Cave내에 서식하는 생물은 7목 9종이 확인 및 채집되었다.

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.

The envirronment of Gosu cave and distribution of inhabitant were surveyed every month from 2002, April to 2003, march. in Gosu Cave, average temperature in summer was $16^{circ}C$ and in winter $14^{circ}C$. Average humidity in summer was $85\%$ and in winter $90\%$. At the entranceof cave in the site 1, trogloxenes:4 species were observed. Troglophiles: Diestrammena japanica was a large population. inside of cave in the site 2 and in the middle Part of the site 3, troglobites:4 species, troglophiles:2 species, trogoxenes: Rhinoiophus ferrumeqinum korai, skleroprotopus laticoxalis longus were observed. Galloisiana sp. were observed on the ground of the Sindong in the site 4, Pseudocrangonyx asiaticus were obserued in the water of yongsu valley. Troglobites have to be preserve as cave animals living in the darkness for a long time.

The research of caves widely deals with geomorphology, meteology, geology, biology, archaeology and physiochemistry. Most famous caves in Korea are in Dongrong Cave in Yongbyun-Goon in 1929, Sungru Cave in Uljin in 1960s. Lava caves were developed as Gymrung Sa Cave, Manjang Cave and Hupje Cave in Cheju Island. Limestone caves, Gosi Cave, Gosu Cave, Nodong Cave and Chundong Cave, were developed for the commercial purposes. Visiting and researching caves are active in Korea. Caves will more be commercialized than before.(omitted)

Pholcus gosuensis sp. novo is described from the entrance zone of Gosu cave, Chungchengbuk-do, Korea. The species is characterized by male palpal organs with three expanded apophyses and developed callosity on procursus, two frontal apophyses of chelicerae and degrading appendix, and sclerotized arches on uterus externus. The species is related to P. crassus Paik 1978 and P. acutulus Paik, 1978 in having identical uncus and embolus but differentiated from those species by the combined characters of large apophyses and heavily sclerotized callosity on procursus, and structure of arches on uterus externus.

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

Cavernocypris gosuensis n. sp. (Cyprididiae, Cypridopsinae), a new subterranean ostracod species is described with figures of female valves, mouthparts, appendeges and SEM photos from Gosu cave, Danyang-Gun, Chungcheongbuk-Do in Korea. The new stygobiont speices is sixth of the genus Caveroncypris Hartmann, 1964 that characterized by both valeves with a median concave part in ventral view and two groove lines in dorsal view, the reduction of the furca, which is flagellum like in female and the left valve ventrally overlaps the right valve when the carapace is closed and can be distinguished from its congers by left valve with 6 muscle scars in innerpart, mandible palp with one claw and 3 setae on the terminal segment and without seta on the exterodistal border of segment III. The animals were collected within pH 7.31-8.74, temperature ($^{\circ}C$) 13.0-14.6 and dissolved oxygen (mg/l 6.75-14.84 from Aug.2003 to Sep.2004.
