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.

In this study, a dynamic numerical model, FLDWAV, is used for analyzing the backwater effect of flood stage in YeongWeol station, which is located on the confluence upstream where Pyeongchang river joins Han river. Given various inflow discharges of both main stream and tributary, the feasible stage-discharge relationships at the YeongWeol station and the upstream range of the backwater effect were computed. The results show that the relationships are completely different according to each of the inflow discharges from tributary and the maximum difference of stage is about 4.0 m. Therefore, the development of a single relationship of stage and discharge is very difficult problem in the zone of backwater effect. The increase of stage in the junction due to the lateral inflow has an effect on upstream stage up to about 8.0 km. The well-calibrated and verified dynamic wave routing model will be a useful tool for the flood forecast in the zone of backwater effect rather than conventional hydrological routing model.

The composition of endophytic fungal species from Pinus koraiensis was studied in two areas (Yeongwol and Jincheon), Korea. To identify 113 isolates, rDNA ITS regions were sequenced. On the basis of the ITS sequence, Pestalotiopsis sp. was the most frequently isolated species in both areas. Pestalotiopsis sp. (68.5%) and Lambertella sp. (12.4%) were isolated frequently in Yeongwol, whereas Pestalotiopsis sp. (41.7%), Hypoxylon sp. (20.8%) and Phomopsis sp. (12.4%) were dominant in Jincheon. Hypoxylon sp. and Phomopsis sp. were not found in Yeongwol.

As extraction solvent, ethanol fraction was revealed the highest anti-microbial activities. The butanol, ethyl acetate and chloroform fractions were also revealed anti-microbial activities with less extent compared to ethanol fraction. All fractions exhibited to inhibition of bacterial growth regardless gram positive and negative, yeast and fungi, however, was not exhibited effectively to their growth. In the inhibition activities against E. coli, the complete inhibition concentration of Yecheon propolis were at 0.40mg/ml, respectively. Complete inhibition concentration of Youngwol was revealed at 0.25mg/ml after 12 hours incubation. In the inhibition activities against P. aeruginosa, the complete inhibition concentration of Youngwol propolis wat at 0.20mg/ml. Yecheon propolis was reveraled the inhibition at 0.20mg/ml after 12 hours incubation. In the inhibition activities against S. typhimurium, the complete inhibition concentration of Youngwol propolis was at 0.20 and 0.25mg/ml and Yecheon was 0.40mg/ml. The Minimum Inhibitory Concentration (MIC) of ethanol extraction fraction of Yecheon propolis to P. aeruginosa, S. aureus, and S. typhimurium were > 0.2, 0.25, 0.25 and 0.4∼>0.5mg/ml, and of Youngwol propolis to P. aeruginosa, E. coli, S. aureus, S. typhimurium, B. subtlis and C. utilis were 0.15, 0.25, 0.25, 0.3 and 0.4mg/ml, respectively.

The duplex system has been considered as an important slip-transfer mechanism to evaluate the evolution of orogenic belts. Duplexes are generally found in the hinterland portion of fold-thrust belts and accommodate large amounts of total shortening. Thus, understanding its geometric and kinematic evolution can give information to evaluate the evolution of the entire orogenic belt. Duplexes are recognized as closed-loop thrust traces on map view, indicating higher connectivity than imbricate fans. As originally defined, a duplex is an array of thrust horses which are surrounded by thrust faults including the floor and roof thrusts, and imbricate faults between them. Duplexes can accommodate regional layer-parallel shortening and transfer slip from a floor thrust to a roof thrust. However, an imbricate fault is not the only mean for layer-parallel shortening (LPS) and displacement transfer within duplexes. LPS cleavages and detachment folds can also play the same role. From this aspect, a duplex can be divided into three types; 1) fault duplex, 2) cleavage duplex and 3) fold duplex. Fault duplex can further be subdivided into the Boyer-type duplex, which was firstly designed duplex system in the 1980s that widely applied most of the major fold-thrust belts in the world, and connecting splay duplex, which has different time order in the emplacement of horses from those of the Boyer-type. On the contrary, the cleavage and fold duplexes are newly defined types based on some selected examples. In the Korean Peninsula, the Yeongwol area, the western part of the Taebaeksan Zone of the Okcheon Belt, gives an excellent natural laboratory to study the structural geometry and kinematics of the closed-loops by thrust fault traces in terms of a duplex system. In the previous study, the Yeongwol thrust system was interpreted by alternative duplex models; a Boyer-type hinterland-dipping duplex vs. a combination of major imbricate thrusts and their connecting splays. Although the high angled beds and thrusts as well as different stratigraphic packages within the horses of the Yeongwol duplex system may prefer the later complicate model, currently, we cannot choose one simple answer between the models because of the lack of direct field evidence and time information. Therefore, further researches on the structural field investigations and geochronological analyses in the Yeongwol and adjacent areas should be carried out to test the possibility of applying the fold and cleavage duplex models to the Yeongwol thrust system, and it will eventually provide clues to solve the enigma of formation and its evolution of the Okcheon Belt.
