There are many beautiful volcano caves in Je-ju island which is biggest volcanic island in Korea. The typical volcano caves are ManJang-gul, HyupJe-gul and MiCheon-gul, etc. Among them the MiCheon-gul name is originated from the beautiful things of cave which were more than thousands in there. This MiCheon-gul cave has another feature in special. It is about a native plant bracken living among the various live creatures and plants in MiCheon-gul cave, however, it is growing contrary under the vertex of the cave grown at retro-gravity, as one of the famous things of the proud cave. Therefore, it was contemplated and investigated on the habitat of a mode of life and ecological adaptation on the native plant of bracken include the geomorphic and geographic features of the MiCheon-gul cave.

The modern people spend more time with heir family on weekends, and this changed the perspective toward leisure and tourism. Along with this, the recognition toward tourism resources have underwent various modifications with the increasing number of family tourists. Caves are categorized as lava tube (formed by volcano activity), lime stone cave(formed by absorption of water into underground level), sea cave (formed by wave erosion) and artificial cave that were made for the fluent traffic activity of railways or roads. Caves manifest characteristics of tourism as a natural resources and tourism as a humanity study, so caves are valuable as a multipurpose tourism resource.

The volcanic edifice of Ulleungdo is largely divided into a shield volcano underwater and a tholoide above seawater. The geological features of the volcano above seawater are basically alkali volcanic rocks that are further divided into five geological strata: agglomerates and tuffs trachyte and phonolite trachytic pumice trachyandesite, and sedimentary layer. The topography of Ulleungdo consists of volcanic landform on the whole, and such volcanic landform is weathered and eroded into various weathering landform, stream landform, coastal landform, structural landform, etc. Major volcanic topography includes caldera basin, central cone, and columnar joint, whereas weathering topography features, tafoni, gnamma, tor, weathered cave, talus, etc. In major coastal topography are sea cliff, wave-cut platform, sea stack, sea arch, sea cave, shingle beach, coastal terrace, etc. For stream topography, its development is minimal except for waterfalls.

The lava-calcification which was found in Geunjisul located in Jeju-do (Korea) was investigated to analyse the cause of calcification through the internal factor of cave structure and surroundings in company with relevant ecological system. The volcanic cave is degenerated after formation from volcano lava extravasation, however, the cave became more stronger with solidification and petrification by the reinforced structure of calcification as the cement in concrete buildings unprecedentedly if the lava-calcification occurred in the cave. Such a Progressive Phenomena of lava-calcification was verified in progress first in Geonjigul located at Hyubjae-ri, but those would be found in other simiiar case of caves distributed and connected with seaside of shelly sand beach.

The geological survey of the Mokdo island is for the fist time conduted in Korea history. The island had erupted before $70{\sim}80$ million years as a strato-volcano. The original volcano had been dissected for long periods up to the skeletal stage through the planeze stage. If the island area is surveyed afterwrds in detail, the position of crater is available to be found, either. The coastal terrace is found at 50m level in Mokdo island which is correlated to its fourth plane. The microgeomorphological features as coastal terrace, cliff, sea cave, wave-cut bench, sea stacks, notch, and tafoni, etc. were described. The Mogdo island is located off Molundae at the extension of Nagdong Jeongmaeg(낙동정맥 洛東正脈) showing a "floating turtle". The name of Mogdo island is needed to change to the "Yoo-goo-do" which means the swimming turtle. The Mokdo island is as suitable tourist attraction for if has enough touism sesouccesein sea. The deuelopsment of coartal sightseeing anound lighthoure and uninhabited islands will hare an impontant effect upon construction of the oceanic capitol city of Busan Haabor. The master plan built up an arboretum on the island, a coastal oceanarium, a seaweeds garden under sea coast, and other oceanic culture-spaces is completed in the study.

The objectives of this study are to investigate the natural heritage and scientific value of various geosites on Udo Island, and to evaluate the sites as natural monuments and as world natural heritage properties. Udo Island includes a variety of geoheritage sites. Various land forms formed during the formation of the Someori Oreum formed by phreatomagmatic eruptions. The essential elements for the formation of Udo Island are the tuff cone, overflowing lava and overlying redeposited tuff sediments. Various coastal land forms are also present. About 6,000 years B.C., when sea-level rose close to its present level due to deglaciation since the Last Glacial Maximum, carbonate sediments have been formed and deposited in shallow marine environment surrounding Udo Island. In particular, the very shallow broad shelf between Udo Island and Jeju Island, less than 20 m in water depth, has provided perfect conditions for the formation of rhodoids. Significant amounts of rhodoids are now forming in this area. Occasional transport of these rhodoids by typhoons has produced unique beach deposits which are entirely composed of rhodoids. Additional features are the Hagosudong Beach with its white carbonate sands, the Geommeole Beach with its black tuffaceous sands and Tolkani Beach with its basalt cobbles and boulders. Near Hagosudong Beach, wind-blown sands in the past produced carbonate sand dunes. On the northern part of the island, special carbonate sediments are present, due to their formation by composite processes such as beach-forming process and transportation by typhoons. The development of several sea caves is another feature of Udo Island, formed by waves and typhoon erosion within tuffaceous sedimentary rocks. In particular, one sea cave found at a depth of 10 m is very special because it indicates past sea-level fluctuations. Shell mounds in Udo Island may well represent the mixed heritage feature on this island. The most valuable geoheritage sites investigated around Udo Isalnd are rhodoid depostis on beaches and in shallow seas, and Someori Oreum composed of volcanoclastic deposits and basalt lava. Beach and shallow marine sediments, composed only of rhodoids, appear to be very rare in the world. Also, the natural heritage value of the Someori Oreum is outstanding, together with other phreatomagmatic tuff cones such as Suwolbong, Songaksan and Yongmeori. Consequently, the rhodoid deposits and the Someori Oreum are worth being nominated for UNESCO World Natural Heritage status. The designation of Someori Oreum as a Natural Monument should be a prerequisite for this procedure.

The purpose of this study was to identify the effect of imagery therapy on "coping mechanism and type C personality of the women with mastectomy. To achieve this purpose, 2 hours sessions of imagery therapy were given to the patients with breast cancer twice a week for 6 weeks. The period of data collection was from July, 7th to August, 12th 2002. The participants were 30 patients, 15 experimental group, 15 control group who were treated at the G University hospital in J City. This study was designed using a quasi-experimental approach with non-equivalent Pre test-Post test Design. The themes for the Imagery Therapy Program were composed of Leuner's(1969) 12 Imagery Themes: flower, green-field, stream, mountain, house, woods, significant figures, rose, lion, ideal self-image, cave and volcano. The data were analyzed with ${\chi}2-test$ and MANOVA using the SPSS program. The course of image change of the 12 imagery themes was analyzed by content analysis. The results of this study are as follows: First Hypothesis, 'The score of type C personality in the women with mastectomy who received imagery therapy will be significantly lower than that of the control group' was supported(p<.05). Second Hypothesis, 'The score of coping mechanism' in the women with mastectomy who received imagery therapy will be significantly higher than that of the control group' was rejected. In conclusion, imagery therapy is suggested as an effective nursing intervention to change type C personality of the women with mastectomy, but not effective to improve coping mechanism. Therefore, the program for the women with mastectomy should be developed to change their coping mechanism, method of problem solving and Quality of life.
