This paper is to inquire into nature of the educated's geography from 1905 to 1910 by researching relevant geographical resources in HAKBO published by the Academic Society. At that time, the Patriotic Enlightenment Movement was active, and the Academic Society attempted to enlighten people, to enrich the country, and to restore the sovereign right. The educated tried to understand the reality in view of social Darwinism and make their country the winner as well as the fit in the struggle for existence by this movement. Their effort can be seen in HAKBO and geography in it. The contents of geography in HAKBO was related to world-wide geographical information and intended to instil patriotism into the hearts of people. As their research methods, they adopted systematic geographical method by comparing between region and region, or studying relationships of the nature and human, and Hettner's regional geographical method which describes human after the nature. Hence, it is proved that the educated's geography in HAKBO introduced modem geography in western society for Patriotic Enlightenment and it used its geographical methods.

To address unsolved issues of change detection in animated choropleth maps, we proposed the concept of 'gross change detection' and performed an experiment that empirically verifies the incidence of change blindness stems from the 'magnitude of change (MOC)', spatial distribution in animated choropleth maps. We generated experimental materials using the change-characterization arrays and the global Moran's I. Participants had 108 cases of changing maps with time duration (1 to 3 sec) and had questions. The results showed that MOC and duration affect gross change detection, but the most interesting result from our experiment was that different spatial distributions between two adjacent choropleth maps may lead the map reader to under- or over-estimate the level of gross change in the map. It implies that we should consider spatial distribution of change when we design animated choropleth maps.

This paper presents an evaluation of stream restoration projects in Seoul with a focus on dissolved oxygen. Five test sites across four streams were measured for dissolved oxygen (DO) in late May to early June in 2012 and compared against a set of minimum and maximum thresholds. Only one test site, Hwarang-cheon, showed measurements below 6 mg/l DO. Towards the upper limit, the Hwarangcheon site was the only tested stream which was not at risk of DO supersaturation. The Danghyeon-cheon site had the highest probability of supersaturation, with DO saturation exceeding 130% expected 86.5% of the time. When measured every hour during daytime, DO levels showed diurnal variations, peaking in the afternoon. However, they showed inconsistent results along transects of the streams. Overall, the streams are rich in DO. To maintain the streams in good standing, nutrient loading should be addressed to prevent potential algal bloom induced hypoxic events down the line.

Liao River with the largest basin area in the northeastern part of China has constructed huge floodplain along the lower reach. Especially a vast marsh was developed around estuaries and coastline near Liaodong Bay. The marsh was called as Yotaek(or Liaoze) before the modern time, which is meaningful for understanding human life since prehistorian times. By the analysis of historical documents and geomorphic data, it can be assumed that the height of Yotaek of landward boundary reached 20~30m from Heishan to Liaoyang during Han dynasty. The shoreline of 7,000 yr BP is estimated to coincide with the contour line between 20m and 30m at present. And the ancient shoreline during Christ era indicates 10m.a.s.l., which is corresponding to the seaside boundary of the Yotaek. The shoreline of Liaodong Bay was progressed seaward 30km/ka during 1000~1100 AD, while 10~40km/ka during late 19 century ~ early 20 century.

While much has been written about Imperial Japan's encounter with geopolitics and developing ideas about Geography as a political and cultural discipline, little if anything has been written about relational and research Geographies between Japan and Silk Roads both ancient and modern. Memories of the ancient Silk Road were revivified in the late 19^th century in tandem with the Great Game of European nations, as Japan modernized and sought new places and influence globally following the Meiji restoration. Imperial Japan thus sought to conquer and co-opt spaces imagined to be part of or influenced by the ancient Silk Road and any modern manifestation of it. This paper explores a particular process in that co-option and appropriation, research collaboration between institutions of the Empire. In particular it considers the exploration of Mengjiang/Inner Mongolia after its conquest in 1939/1940, by a collaborative team of Korean and Japanese Geographers, led by Professor Tada Fumio. This paper considers the making knowable of spaces imagined to be on the ancient Silk Road in the Imperial period, and the projecting of the imperatives of the Empire back into Silk Road history, at the same time as such territory was being made anew. This paper also casts new light on the relational and collaborative processes of academic exchange, specifically in the field of Geography, between Korean and Japanese academics during the Korean colonial period.

The Yangsan Fault is one of the main fault systems in the Korean peninsula. It can be divided into three segments (northern, central, and southern) by its paleoseismic and structural geologic properties. Based on the geomorphic features of the northern segment, which includes the Yugye Fault, we identified deflected streams as a geomorphic marker of strike-slip component of the fault, and knickpoints along the streams as evidence of dip-slip component of the fault. Geomorphic analyses showed that (1) the horizontal displacements of deflected streams decreased and (2) the retreat amounts of knickpoints tend to increased toward north along the lineament. We interpreted the variations caused by strain partitioning; that is, there might be some increases of the vertical component toward north, whereas the main strike-slip fault system dies out, splaying into horsetail structure toward north. Based on the response time of the landforms, these interpretations imply that (1) there were differences between horizontal slip rate and vertical slip rate along strike, and/or (2) there were different timings between horizontal and vertical deformations by fault.

This paper aims to analyze the root mean square errors of MODIS LST data and inland water temperature measurement data in order to use MODIS LST data as an input of numerical weather prediction model. MODIS LST data from July 2011 to June 2012 were compared to water temperature measurement data in the automated water quality measurement network. MODIS data have two composites: day-time and night-time. Monthly errors of day-time and night-time LST range $2{\sim}8^{\circ}C$ and $3{\sim}12^{\circ}C$, respectively. Temporally, monthly errors of day-time LST are less in fall and those of night-time LST are less in summer. Spatially, on the four major rivers including the Han, Nakdong, Geum, and Yeongsan rivers, the errors of Yeongsan river were the smallest, which location is the south-most among them. In this study, the errors of MODIS LST as an input of numerical weather prediction model were analyzed and the results can be used as an error level of MODIS LST data for inaccessible areas such as North Korea.

This study considered the history and range of concern to the citizenship education in the British geography education with respect to the appearance of the citizenship subject in National Curriculum. Although British geography education mainly put on emphasis citizenship education focused on national identity through imperialism ideology up to World War II, it has aimed at the local and global citizenship education which put focus on the reflection of students to individual value and value position, and social justice after the 1980s. Not only an inner change of such geography education but the external factor of appearance of citizenship subject has stimulated more concern about citizenship education. After that, British geography education community constructs the logic of theoretical justification and urges teachers' practical research and continuous concern as plan for geography subject to lead citizenship education all the time. On the other hand, recently British political and social cultural geographers observe spaces of the citizenship which makes difference and identity and the radical and critical citizenship which put focus on the local and the global scale from the national. Therefore, citizenship education through geography subject must put more emphasis on not national identity but the local and global identity for social justice and a better world.

Both Earth science II and Korean geography textbooks emphasize the importance of content related to 'geology of the Korean Peninsula'. This study aimed to analyze the differences in the content related to the 'geology of the Korean Peninsula' presented in the textbooks, and to find out whether these differences are consistent with the latest scientific knowledge in any inconsistencies are found. For this purpose, seven textbooks (four Earth science II and three Korean geography) published under the 2015 revised curriculum were selected as the subject of analysis, and the difference in the description of the tectonic provinces of the Korean Peninsula, geologic time scale, and explanatory texts of geological characteristics between Earth science II and Korean geography textbooks were compared. As a result of the analysis, there are some cases of inconsistencies between Earth science II and Korean geography textbooks in terms of terminologies, names, and distribution ranges related to the tectonic provinces of the Korean Peninsula. The Korean geography textbooks had inconsistencies in the geochronologic data of the rocks as they cited outdated data. In addition, inconsistencies were found in the explanatory texts describing the 'distribution of rocks on the Korean Peninsula', 'characteristics of the Pyeongan Supergroup', and 'great hiatus of the Paleozoic Era'. Both Earth science and Geography have many concepts in common, therefore, effort is needed to minimize the differences in content. It is important to select the content appropriately which should reflect the latest scientific knowledge and presents the concepts consistently.

The core version of UDC(Universal Decimal Classification) is available in an electronic form called MRF(Master Reference File) which supports the maintenance of the quality of the scheme as a working tool for the UDCC(UDC Consortium) by annual reviewing its content and initiating revisions and extensions. In this paper, we discuss outcomes of our in-depth analysis of the geography, biography and history disciplines in UDC focused on the its evolutions and characteristics, including the common auxiliaries of place, the common auxiliaries of time and the common auxiliaries of race, ethnic grouping and nationality. Based on the in-depth analysis, we suggested some ideas which can be applied into the history class of KDC(Korean Decimal Classification). In particular, its principle of combination methods in the history of individual regions, the way of its assignment of physical geography and human geography in the same division, the possibilities of the extension of the table of geographical division and the adaptation of the table of chronological division in KDC.
