This study analyzed the structural characteristics of the high school travel geography achievement standards in the 2015 revised curriculum of South Korea. The achievement standards of the travel geography curriculum was analyzed using the KrKwic, which is a sematic analytic software that processes Korean linguistic markers. The results of this study show that the keyword travel had a semantic pattern that linked geographic concepts and career education, which was one of the problems faced by the earlier curriculum. This is considered a positive pattern because it implies that the new travel geography curriculum greatly reflect the subject’s educational objectives. This study proposes to strengthen learners’ understanding of travel geography by creating more links between travel to other target geographic and educational concepts. These changes in learners and travel geography curriculum are expected to contribute to strengthen the identity of travel geography.
The whole area of the Samsuryeong Pass is a representative mountains of Korea and the deposits of the limestone and anthracite. Therefore, there is a rich cultural and historical heritages which is related to the geoheritages. The aim of this study is to present an applicable alternative to the geotourism of Samsuryeong Pass after exploring geographical implications and geoheritages with Samsuryeong Pass. It is one of the best places which has high potentials of the quantitative and qualitative development of geotourism. Therefore, the development of geotourism which is focused upon Samsuryeong Pass, may contribute to the preparation of Taebaek-si for a geopark’s certificate.
This study confirms the border mismatch areas between the Baekdudaegan as typical natural boundary and provincial (Do) boundary as representative artificial boundary in South Korea, and examines the landscape features of each area. The border mismatches between the Baekdudaegan and the Do boundary appear total eight areas, such as each one area of Bonghwa and Yeongju at Gyeongsangbuk-do, each two areas of Munkyeong and Sangju at Gyeongsangbuk-do, a area of Namwon at Jeollabuk-do and a area of Gurye at Jeollanam-do. Of these, the area of the western part of Sangju is the largest of about 285.86 km2, and the area of eastern part of Namwon is next of about 254.09 km2. Many these border mismatch areas have discomforts of living and transportation of area resident, conflict of neighboring municipalities and problems of administrative management and land registration owing to discordance between administrative district system and life zone.
Previous studies on fluvial landforms in Chungcheongbukdo (Province) are reviewed in this study. Various micro-forms, like pothole and grooves, are found from channel bed of mountain streams incising granite area of Sobaek mountain range. However only the forms at Hwayang valley area were studied. Fluvial terraces can be found from the Danyang area, mid reach of the Nanhangang (River). Lower terrace of this area are regarded as fill terrace, while upper terraces are weathered strath terrace. There are some proposed hypothesis on the age and forming processes of terraces, but further scientific analysis on the chemical composition of weathered sediment and burial ages are needed. Number of abandoned channels are formed by meander cut along the head and mid reach of Dalchen (River), a tributary of Namhangang. Information on the burial age of the sediment can contribute to the studies on the landform change of Sobaek mountain range. Abandoned palaeo-channel and terraces can be found from the Chogangcheon (River) in Yeongdonggun, southern part of Chungcheonbukdo.
There are previous studies on fluvial terraces along the Mihocheon(River), the forming age and processes of terrace are reported recently.
The characteristics of rainfall simulator are so important for the laboratory experiment of landslide and sediment runoff. To analyze the characteristics of the newly designed rainfall simulator and decide its optimum operating methods, we measured the rainfall intensity and the kinetic energy of raindrops with three cases; Case I: different nozzle combinations and different input currents, Case II: only different nozzle combinations, and Case III: only different nozzle sizes. On the base of the measuring results, we suggested two optimum conditions (condition 1 and 2) for the artificial rain simulation. Although there was large difference between the characteristics of natural rainfall and those of simulated rainfall, the kinetic energy distribution of newly designed rainfall simulator was similar to those of many previous studies. However, the new design of rainfall simulator having the characteristics of natural rainfall will be needed for further detailed laboratory study reflecting the natural conditions.
In the view of geomorphology, the study on sediment yield is not only an important issue that needs to be addressed, but they are vital for the prediction and evaluation of natural hazards. Many studies are focused on the accuracy of model performance, although sediment yield researches based on various types of geologies are also important. To investigate the properties of sediment yields on two different geologies, i.e. granite and gneiss in small watersheds, the GeoWEPP model, which is integrated with GIS and Water Erosion Prediction Project model, was applied in this research. During the monitoring period, the amount of sediment yield was measured to be 270.54 tons at the granite area and 31 tons at the gneiss area. The results showed that when the measured data and simulated data were compared, an acceptable difference of –12.46 and +0.96 were observed for the granite area and gneiss area, respectively. However, though the model showed acceptable performance, it is still necessary to compare the model assumptions with the surveyed geomorphological investigations. This suggestion is necessary due to some geomorphological variations detected in both research sites, which deviates from the model assumption.
In this study, research is empirically conducted to estimate a variety of indicators related to urban regeneration in Incheon Metropolitan City, and visualize the result through GIS. In this way, it is intended to observe not only the required area but region differentiated factors for urban regeneration. The GIS and the factor analysis are used and results are as follows. It is observed that seriously declined old city physically and economically are required for urban regeneration. In other word, the required area for urban regeneration is the area with high factor loadings because of aging rate (+), aged dependency ratio (+), percentage of old housing (+), percentage of owner-occupied housing (+), average years of education (-), and business start-up rate (-).
Therefore, the government should perform the project by determining accurately required area for urban regeneration grasping various indices related to local economical activities of micro space unit rather than considering simple physical factors to improve the efficiency of the project purpose.
