This study estimates possibility and limitation on production of DEM using aerial photo by comparison of DEMs using aerial photo and digital map. Mountain and urban areas show higher elevation in DEM using aerial photo than in DEM using digital map, due to height of vegetation cover and buildings, respectively. However, artificial affects due to bridge, embankment and road construction are responsible for areas with higher elevation in DEM using digital map than in DEM using aerial photo. This difference in elevation between DEMs seems to be caused by rapid change in real elevation that is not reflected in digital map. There is little difference in elevation between DEMs in plain and area with little or no vegetation cover. This study suggests that problems associated with vegetation cover and error by GCP should be fixed, although DEM using aerial photo can quantitatively and 3-dimensionally reconstruct topography with a high resolution.

This study analyzed problems of interpretive signs along Eorimok-Yeongsil Trail on Mt. Hallasan National Park, focusing on factors of distracting visitor's attention from reading and understanding the signs. Eorimok-Yeongsil Trail has a total of 86 signs, and according to their purpose and content, they are classified into thirteen general signs, sixteen location signs, nine safety signs and forty-eight interpretive signs. Interpretive signs provide visitors with information and explanations about the nature and human resources of Mt. Hallasan as well as enhancing the opportunity for self-guided interpretation. The contents of interpretive signs of Eorimok-Yeongsil Trail are composed of landscapes, flora and fauna, topography, geology, history and culture, of which 70.8% of the total are related to plants and animals. Interpretive signs on the Eorimok-Yeongsil Trail do not attract visitors' attention because of the low readability, inappropriate locations and frequent errors in translation from Korean into other languages. The causes of low readability of interpretive signs include thirty-six physically damaged and faded signs, twenty-two improper font sizes and misuse of color schemes and five unclear description signs. The reasons for the incorrect locations include twenty-two long distances from the trails, twenty-one inadequate heights and fifteen inconsistencies in descriptions and locations. Problems with English use include eight grammar and spelling errors, twenty-one incorrect translations, and twenty-six English names missing.

The contract farming scheme of today is a new system that allows the forward and backward linkage of the agribusiness through vertical coordination while also leading the changes within the agri-food system. As contract farming of agricultural products becomes routine in both advanced and developing countries alike, it is gaining the attention of researchers in various fields, including geography. This research discusses the research trends and problems regarding contract farming through literary research on the research progress of foreign researchers on contract farming. The content of the research specifically includes explanations regarding the relationships between the rise of contract farming and changes in the agri-food system and discusses the basic theoretical foundations of contract farming. The research also defines the economic and environmental effects of contract farming and its purpose in regional development policies and concludes with discussions of the possible future research subjects on contract farming.

The main objective of this paper is to provide an adequate and comprehensive review of what has been done in South Korea in the field of geospatial analysis and modeling. This review focuses on spatial data analysis and spatial statistics, spatial optimization, and geosimulation among various aspects of the field. It is recognized that geospatial analysis and modeling in South Korea got through the initial stage during the 1990s when computer and analytical cartography and GIS were introduced, moved to the growth stage during the first decade of the $21^{st}$ century when there was a surge of relevant researches, and now is heading for its maturity stage. In spatial data analysis and spatial statistics, various topics have been addressed for spatial point pattern data, areal data, geostatistical data, and spatial interaction data. In spatial optimization, modeling and applications related to facility location problems, districting problems, and routing problems have been mostly researched. Finally, in geosimulation, while most of research has focused on cellular automata, studies on agent-based model and simulation are in beginning stage. Among all these works, some have fostered methodological advances beyond simple applications of the standard techniques.

Geographical name is not only a spoken or written language that has been constructed as a linguistic element, but it is also a geographical phenomenon and a cultural element. Based upon this consciousness, the purpose of this paper is to examine current classification and management systems of the geographical names in Korea and to propose a new alternative classification and maintenance of the geographical names. In particular, the paper suggests three categories for the type classification of the geographical names: morpheme, linguistic change, and contestation types. In turn, this paper investigates the index of the geographical names contained in THE NATIONAL ATLAS OF KOREA (2007) on the basis of the preceding classification types in order to unveil the practical problems and limitations of the current classification articulated in the national atlas. This paper also proposes a new classification of the geographical naming that reflects the divisions of front and back morpheme of geographical names. Finally, from the discussions with the reinforcement of National Committee on Geographical Names, this paper invokes administrative and institutional protection and systematical management of the contesting and unofficial small scaled geographical names that have been set apart from the current geographical name standardization.

The present paper discusses the relationship between human being and space through 'recognition.' Recognition is the natural desire of human being. Every human being wants to be recognized for what they do in everywhere. Human being enhances their own identity and fight for the raison d'etre to be recognized by others. Hegel's recognition is grounded by a process of mutual recognition based on the subject-object view of human beings. On the other hand, the recognition based on inter-subjectivity is founded by the view of human beings emphasizing "we" on the basis of the relationship between you and I. These two meanings of recognition make it possible to newly recognize the relationship between human beings and space. In the paper, I emphasize the role of geography about the invisible space over the geographical recognition regarding the visible space dealing in previously geography. I expect to be recovered the nature of geography by revealing the invisible space. Also, the geographical discovery is presented about two spaces including inaudible space and unwritable space but having story via '$\acute{e}$criture blanche.' In terms of the discovery, I criticize irrationalities and discrepancies of our society and suggest ways of solving problems. The goal of the discussion is to support the overcoming of the immediate geography crisis as well as communicate with the world as humanity.

This study is to analyze the approaches of development discourse and its representation in geography curriculum and textbooks for middle school in Korea. The paper examines the spectrum of development discourse in terms of modernization theory, dependency theory, neoliberalism, grassroots development, sustainable development, postcolonism, post-structuralism and post-development. The findings on geography textbook analysis based on them are as follows. First, Most of the textbooks don't include the definition and operational definition on development and sustainable development. Second, development indicators rely on normal economic indicators like GDP or GNI per capita. HDI that includes GDP per capita, level of education and life expectancy is treated in some of the textbooks, and gender index is never presented. Third, a textbook still uses biased terms such as developed and most developed countries instead of developing countries. Fourth, in plans to solve economic unequality and geographical problems, personal level is treated less than the global, nation and NGOs. Finally, statements on sustainable development contain only intergenerational equity, not intergenerational equity. And approaches on sustainable development are based on technocentric approaches more than ecocentric approaches. Thus geography textbooks should be carefully written on development discourse by authors.

In 2020 when the COVID-19 pandemic began in full-scale, the WHO Director-General warned of the dangers of an infodemic. The infodemic is a phenomenon in which false information spreads rapidly like an epidemic and causes chaos, and it was noted that the COVID-19 pandemic is not just limited to health problems, but also linked to a variety of issues such as human rights, economic inequality, various discrimination, hate speech, fake news, global governance etc. In the field of education, it is necessary to think about how to connect this global situation with school classes. Accordingly, this study suggested the direction for global citizenship education by analyzing how the infodemic spreads on Korean social media with the case of the recent global COVID-19 pandemic. According to the research results, the rate of negative emotions was higher than positive ones in the emotions that generate infodemic, while anxiety and anger were focused among negative emotions. In addition, the infodemic tended to spread widely with the feelings of anger rather than anxiety, and the feelings of anger led to advocating aggressive policies against certain country and regions. Therefore, global citizenship education is required to focus on a sense of duty and responsibility as a citizen, not on the level of national identity based on an exclusive sense of belonging. Furthermore, global citizenship education needs to lead to presenting a blueprint for education in a way that can enhance the awareness of the global community for joint response to global challenges and realize common prosperity based on sustainability and justice.

Problems caused by the U.S. military bases have attracted little attention until recently due to the national security of S.Korea and the peace of North-Eastern Asia, emphasized from the perspective of macro-geopolitics. However, since the political regime has been democratized and political discourses have been liberalized from the 1990s, those problems become a nation-widely serious social issue, though they have been brought about on the local areas. Thus, it can be suggested that micro-geopolitics is highly relevant and significant in approaching the local problems caused by the U.S. military bases, and ultimately resolving the macro-geopolitical problem of longstanding unfair relations in the SOFA and the withdrawal of U.S. troops. This paper aims to consider local problems caused by the U.S. military bases and resolving strategies from the perspective of micro-geopolitics. First of all, it discusses some significance of the micro-geopolitical perspective, as it has been recently emphasized in political geography in considering local problems and politics of life on the basis of place, then looks on empirically criminal and environmental problems caused by the U.S. military bases, analyses the questionnaire date on the perception of local dwellers around the military camps in Nam-gu Daegu, and finally suggests strategies to resolve those problems, which level up from the micro to the macro-scale of geopolitics.

We examined research trends in geomorphology and hydrogeography in America based on papers presented at the annual meetings of the Association of American Geographers(AAG) and papers published in two AAG journals between 2002 and 2004. Among the 437 papers in geomorphology, $40\%$ of the papers concerned fluvial geomorphology, followed by environmental geomorphology and glacial and periglacial geomorphology concern. Among the 452 papers in hydrogeography, about $20\%$ of the papers focused on water, law and institutional aspects, followed by hydrogeomorphology and hydrologic modeling. Twenty one papers examining geomorphology and hydeogeography were published in two AAG journals, and fluvial geomorpholoy was the dominant theme. GIS was used for $29\%$ papers in geomorphology and $35\%$ of papers in hydrogeography($35\%$), suggesting that other methods, including geostatistics, field survey, and qualitative methods, are employed as well. This methodological diversification seems to be associated with solving such complex environmental problems as integrated watershed management and implies that geomorphologists and hydrogeographers are expanding their traditional territories and are making close connections with human-environment geographers and human geographers. Geomorphologists and hydrogeographers are likely to continue examining the causes of and solving environmental problems that humans are currently facing and might face in the future.
