The aim of this paper is to explore the concept, backgrounds of an geopark's origin, and activity of geopark in geography, and to debate the Korean name of the geopark (or geological park) in controversial. Geopark starts with the collaboration between International Geographical Union(IGU) and International Union of Geological Sciences(IUGS). However, the intention which is establishing the law of geopark (or geological park) within a specific academic realm in Korea, would be wrong. The reason for this argument is that activities in Geopark have aspects of the conservation of natural heritage as well as geomorphological and geological one. Therefore, geopark should not be focused upon a specific academic realm. The geological scope alone seems to be limited. That is why "GEO" is more than geology. "GEO" involves geographical and geomorphological issues as well. Within this context, in Korea where is in the quickening period of geopark, the discussion and agreement with the Korean name of geopark are absolutely imperative.

There has been a lot of controversy over the claim that ancient characters were engraved on a stone plane collected near the Samsin Mountain in Hadong-gun, and that it was used as an altar based on the contents on the stone. The importance of the role of geoscience in prehistoric petroglyph research was presented through analysis and comparison with representative domestic petroglyphs. First, by examining the geological formation process of the collected stone objects, it proved that prehistoric actions were not applied. Second, as a result of comparative analysis from the viewpoints of human geography and topography with representative petroglyphs in Korea, it is unreasonable to argue that the stone was made for an altar. Third, it is considered that among the ancient characters under debate, the straight line indicates a cleavage of carbonate minerals, and the curved shape results from the growth of lichens. Finally, we propose that reproducing the lines found on the stone was impossible by using ancient techniques, and that there was no trace of any artificial actions applied to the spots considered to be curved characters. As shown in such research cases, the results of petroglyph research will have high reliability, if research by experts in each field continues after the geoscientific basis is secured. In this respect, the contribution of Earth science to cultural assets and archeology is expected to increase in the future.

Minor erosional forms in the bedrock river, like potholes, are not just research subject for the professional geomorphologis. In addition, these features attract general public and make them understand the social contribution and importance of geomorphologic research activities. In this paper, the studies on bedrock minor forms in Korea was reviewed. For further researches, some of major erosional processes and minor forms in bedrock rivers were discussed in detail. Cavitation, plucking, hydro-wedging, and abrasion by passing sediment particles are the major processes to create the longitudinal or transverse minor forms like pothole, furrows, flutes, and runnels. Especially the definition of furrows and runnels are explained to prevent the confusion with pothole, weathering pits and grooves. To make a progress in research on bedrock minor forms the quantitative relationship between the variables should be studied. New techniques for scientific estimation of erosion rates and exposure ages of bedrock surfaces should be used in this field.

The purpose of this study is to analyze the scientific characteristics of speleology and to contribute to the scientific establishment of speleology. For this purpose, I analyzed the scientific specialty of speleology, the relation to other sciences and the scientific approaches. In conclusion, the speleology is the applied and synthetic science, so that the effective approach to the scientific establishment of speleology is to study by means of the organic and symmetric approach than the fragmentary and uniform approaches.

본 논문에서는 설악산 아고산대에 나타나는 산정형 암괴원에 관한 여러 가지 논의를 제시하였다. 이 암괴원은 산악인들에게는 너덜지대로 너리 알려져 있었으며, 설악산의 북쪽 황철봉과 귀떼기봉에서 대청에 이르는 서북주릉 상 화강암류의 기반암에 암괴원이 분포하고 있다. 이들 암괴원은 규모가 클 뿐망 아니라 암괴상에는 풍화쇄설물을 가지고 있는 나마(gnamma)와 그루브(groove)를 비롯한 많은 화학적 풍화에 의한 미지형들이 발견되고 있어 한반도의 제 4기 후반의 기후변화와 지형형성 영력을 연구할수 이는 기후지형학적으로 중요한 연구지역이라 하겠다. 본 논문에서는 추후 발표될 암괴원의 성인과 고기후학적 의의에 관한 논의에 앞서 먼저 분포지역에 대한 소개와 몇 가지 이론적 고찰에 관하여 논의를 제한하고자 한다. 국내에서는 테일러스, 암괴류 등에 관한 논의가 상당히 이루어지고 있으나 암괴원에 관한 본격적인 논의는 아직 시작단계에 있다. Landsat 영상에 의한 구조선 분석 결과 구조선 밑도는 설악산 지역에서 큰 차이를 나타내지는 않으며, 암괴원은 대부분 화강암 지역에서 나타나는 것으로 판단된다.

Architecture is builded on the ground and affected environment which include shape of topography and situation. What this study saying is the analysis about the relation between the concept of structural geomorphology and the space modern architecture. As there are many issue about boundary of space and organic architecture, It is important what study about structural geomorphology In paper, we will aware that there are many similarities between architecture and topography. Notion of folded structure in structural geomorphology is connected with continuity or infinity. This is one of many example.

1980년 설치 이후 환경부는 환경정책과 환경관리에 대한 주요 업무 중의 하나로 자연환경의 보전에 주안점을 두고 있다. 또한 자연환경보전법에 의거하여 환경부는 자연환경상태에 대한 전국 단위의 자연환경조사를 실시하고 있다. 제1차 전국자연환경조사는 이미 1986-1990년에 실시하였고, 현재 교수 및 연구진의 참여 하에 제2차 전국자연환경조사(1997-2002)ff 실시하고 있다. 제2차 조사에서는 지형경관에 대한 조사가 포함되어 모든 종류의 지질 및 지형환경에 대한 조사가 이루어진다. 예를 들면 호수와 습지, 해안, 하천, 산지. 평야, 주빙하지형, 화산, 카르스트 및 구조지형 등이다. 조사지역은 육지 206개 소권역, 해안 145개 지점으로 나누고 6년에 걸쳐 매년 약 30개의 팀이 이 프로젝트에 참여하고 있다. 조사결과는 “지형경관도”로 편집, 인쇄될 예정이며 현존식생도, 동식물분포도와 함께 생태자연도로 작성될 예정이다. 제2차 조사에서 얻어진 방대한 양의 환경정보를 합리적이고 효율적으로 이용하기 위해서 환경부는 한경관리를 위한 이용과 응용에 환경정보시스템을 구축하고 있다.

This study on Gobongdond Wetlands have hydrogeomorpholosic charateristics in the southern-west of Gogongsan. This study area have been dissected and deep weathered. in geology, this area show banded gneiss consisting of alternated felsis and mafic layers. in geomorphology this area have 3 slope that surplyed the surface water and ground water, but have a little water source by surface water. The most of Gobongdong wetland's water sources are aquifer or confined aquifer, so this wetlands have many seepages or discharges. The characteristics of Soil have retained the wetland's water. Deep weathering made the parents soil into clay minerals.(siallitization) This clay minerals have a high water table.

오늘날 기후지형학은 지형학자들에게 가장 큰 논점이 되고 있다. 기후적인 외인적인 요인이 제1차적인 형성요인이며, 2차적으로 육수와 해수에 의한 내인적인 발달요인이 된다. 카르스트의 기후 적 접근은 1950년대부터 활발하게 주장되어 현대 진화의 광대한 연구에 가담하였다. 기후적인 작용에 의한 카르스트의 발달은 지대한 영향을 가져오지만 기온에 대한 카르스트의 발달에 대한 논쟁은 기존의 우 열대 저 한대 편향에서 많은 논쟁을 야기시키고 있다. 왜냐하면 한대와 온대, 열대와 중위도 카르스트 간에 어떠한 차이가 있지 않다고 규정짓고 있기 때문이다. 이에 따라 한반도에서도 제4기 동안에 형성된 해수면의 승강작용과 태백산맥의 융기작용에 따른 카르스트의 발달은 지형발달에 지대한 영향을 미친 결과 다수의 지표면 카르스트(카렌)와 지하 동공(동굴)의 발달이 형성되었다.

This study analyzes altitude changes of riverbed at 6 bridges in the upper and lower reaches of Yeongju Dam in Naeseong River, from 2009 to 2016 just before and after the dam construction. For 5 years from November 2010 to December 2015 when the dam was under construction, approximately 0.091m of the riverbed altitude in average more than twice before the dam construction was lowered, because of the effects of riverbed excavation for riverside maintenance in the upper reaches and transport limitation of flow and sediment by the dam in the lower reaches. Between November 2009 and December 2016 when the dam was in pre-construction and post-construction stages, respectively, the most sites in this study in the upper and lower reaches showed lowering in the riverbed altitudes. On the other hand, the riverbed around Hoeryongpo closed to the river mouth seems to be influenced by channel changes in Nakdong River rather than by the dam construction.
