Recently planification and effort for management, assessment and discovery of geological heritagesare being increasingly demanded with institutional strategies such as geopark, as their preservation is asked socially. In this study, we discovered geological heritages in the Jeolla Province and then performed assessment of the value and grading of them and finally suggested a promising and suitable site for the National Geopark. A total of 325 geological heritages are listed on literature review and then detailed description in field and assessment of the value for selected 158 geoheritages are completed. The assessment items are categorized into intrinsic value, subsidiary value, and preservation/management part. The intrinsic value is subdivided into scientific/educational value, composed of representativeness, rarity, geodiversity, typicality, reproducibility, and particularity, and geomorphological/landscape value composed of scale, naturality (integrity), scenery (aesthetic value). Also, subsidiary value consist of 7 subsections of soil function, ecological function, tourism value, geological resource, historical value, folk tale or legend and symbolic value, and accessibility, convenient facility (infrastructure), management condition (legal protection) is evaluated in preservation/management part. The heritages in the Jeolla Province subdivided into three types: 73 geological heritages, 42 geomorphological heritages, and 42 composite heritages. Based on points acquired in intrinsic value, all geological heritages are graded Class-I to -V. As a result, numbers of geoheritage belong to Class-I (protection at world level), -II (protection at national level), -III (nationdesignated management), -IV (involved management list), -V (candidate management list) are 12, 39, 52, 34, 21, respectively. Finally, we construct database based on Arc-GIS with all informations for each geological heritage and suggest three promising and suitable sites, 'Jirisan-Seomjingang Area' and 'south coast area of Jeolla Province', for the National Geopark.

Various geological structures are found on the slope of Bangnim district in Pyeongchang, Gangwon-do, based on the Paleozoic Joseon Supergroup Limestone. The recumbent fold observed on the slope is a very rare geological structure that has not been found in Korea, and has important academic value in exploring the formation process of the Paleozoic geological structures in the Gangwon region. In this study, discussed the geological value of the geological structure observed on the slope of the road, and studied the management method of rockfall problem slopes. The state of development of recumbent folds has conservation value in geological scarcity and specificity. Preservation management measures should be prepared through the protection of slopes and measures to reduce of rockfall risks as geoheritage with an important value in geology science and education. Furthermore, it is expected to be preserved and utilized as a geopark.

This study aims to investigate geomorphological and geological landscapes in the Taeanhaean National Park to ensure they are well-preserved. This study discovered 390 geomorphological and geological landform resources distributed in the coastal zone of Taeanhaean National Park. Representative geomorphological and geological landforms include : sea cliffs, sea caves, wave-cut platforms, sea-stacks, pebble beaches, sand beaches, tidal flats, coastal dunes, coastal dune wetlands and folds (or micro folds) landforms. Deposition landforms are developed more and erosion and weathering landforms are less on the land zone than island zone. These landform resources vary from district to district and can be developed for geo-tourism resources. Combined efforts from the Taeanhaean National Park authorities and residents are essential to manage ecological programs using geomorphological and geological resources.

Daisetsuzan National Park in Hokkaido, Japan, has an extensive alpine region due to the topographic feature of lava plateau, and exhibits the surface geology largely composed of pyroclastic materials. In addition, the peak season of mountain climbing in the park coincides with a snow-melting period, resulting in severe soil erosion along hiking trails generated by human trampling, snow-melting water and pipkrake. Trail section has been particularly enlarged because the snow-melting water scours a trail surface and the pipkrake erodes sidewalls of a trapezoid-shaped trail. The scoured tread also forces hikers to walk out of a trail, and then frequently brings about path divergence as well as path widening. The soil particles, which are produced by erosional processes in a slope reach, flow downward, and cause the secondary trail degradation by covering a tread in a flat reach and nearby grassland.

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.

The purpose of this study is to develop teaching materials for geological fieldwork around the area of Mai Mountain and to analyze the responses of elementary teachers as to the application of fieldwork. The site of geological fieldwork, Mai Mountain area, is located around the Maisan Provincial Park of Jinan-gun, Jeonbuk Province where a large-scale sedimentary succession in the era of Cretaceous is shown. It provides an easy access to distinct outcrops around the provincial park. The sequences reveal different kinds of sedimentary rocks and various sedimentary structures, and provide information of the lacustrine sedimentary environments of the Cretaceous. In addition, metamorphic rocks and structures formed at the margin of the basement and the basinal fault as well as a sedimentary sequence of the Quaternary formed in a modern fluvial stream are observable. A 4-step fieldwork procedure was applied to a group of 13 elementary teachers. Through questionnaire and interview, results showed that (a) the geological fieldwork and materials were effective to positively increase science teaching from the participating teachers, and that (b) there is a great need of the development of various fieldwork sites and teaching materials that promote active fieldwork for students to have their lived experience and knowledge gain. It is suggested that teacher education programs be able to provide active fieldwork for elementary inservice teachers to properly carry out a geological fieldwork for their students.

The geomorphic properties of potholes at Naerin River, Inje-gun are analyzed to discover the geosites of DMZ geopark in Gangwon-do. The furrow-type potholes along the river flow are mainly found in the P1 and P2 sites. The P3 site can be divided in to the zones where the furrow-type potholes densely distribute and various types of potholes are scattered, while the various types of small potholes are scattered in the P4 site. After measuring the 44 potholes, the potholes with a U-shaped cross-section, similar directivity with river flow and deposited gravels with in them show large values in length, width, depth and slope. Because the P1 and P2 sites are characteristic in the scales and forms of potholes and show beautiful scapes, it can be suggested that they are suitable for the geosite developments.

The aim of this study is to reevaluate the elements of Gokungugok in geomorphic perspective to discover the geosite of DMZ Geopark in Gangwon-do. The perception for the landscapes contained in Gokungi and Gokungukok-ga is similar to today's geomorphic elements. The most frequent geomorphic landscape shown in Gokungukok is ripple-pool system, and follow after falls and bedrock stream bed. The potholes along the granite bedrock of 3rd and 4th sites accentuate the beauty of Gokungugok. Between 1st and 3rd sites are very long section, and there are many beautiful sceneries, but between 7th and 9th sites is very short section and there are no distinct geomorphic landscapes. After a historical review for the position of 'Seolbeokwa', 'Mangdangi' and 'Beokuiman' called by Dasan Jeong Yak Yong, there is necessary to establish the name and the position of New Gokungugok. Because Gokungugok consists of the beautiful geomorphic landscapes and is well preserved, it can be suggested that it is a suitable geosite.
