Reducing the range of target landform, is required to save the time and cost before real field survey in the case of inaccessible landform such as talus. In this study, Weight of Evidence modeling, which is a Target-driven spatial analysis statistics methods, has been applied to reduce the field survey range of target landform. In order to apply the Weight of Evidence analysis, a likelihood ratio was calculated on the basis of the result of correlation analysis between geomorphic factors and GIS information after selection of geomorphic factors regarding talus. A best combination, which has the biggest possibility for Talus Potential Index, was found by using SRC and AUC methods after calculating the number of cases for each thematic maps. This combination which includes aspect, geology, slope, land-cover, soil depth and soil drainage factors, showed quite high accuracy by 74.47% indicating the ratio of real existent talus to potential talus distribution.

This study aims to review what geographers have contributed to GIS industries and national needs. To-be-geographers and geographers are expected to meet the gap between what we have teamed in school and what we have to do after graduation. The characteristics of GIS industry in the 1990 are summarized with approximate evaluation of the contribution of geographers in each stage. Author introduced the requirement for the licenses of geomatics and geospatial engineering experts and the other licenses, which are important to get a job in GIS industry from 2003 to 2004. A set of questionnaire on the user's requirements was given to GIS people in private companies and public GIS research centers and analyzed. Author found that they put an emphasis on hands-on experiences and programming skills. no advantages or geography such as capability or integration and inter-disciplinary collaboration were not appreciated. The prospects for the GIS tend to be positive but the reflectance of the prospect was not accompanied by at the same degree of preference for geography. Most government strategies for the next ten years' GIS focus on new-growth leading industries. SWOT(strength, weakness, opportunity, threat) analysis of geography for GIS industry will give some directions such as telematics, regional marketing strategies with web-based GIS technology, location based service. That means intra-disciplinary study in geography will evoke the potentiality of GIS, compared with interdisciplinary studies.

This paper suggests an inquiry into the characteristics and implications of urbanscapes produced by Internet cafes, widely called PC Bangs in Korea, and their effects on the motions and boundaries of human bodies as cyborgs which exist in between actual and virtual spaces or between human and machine spaces in PC Bangs. The paper, which is organised into two main sections, first investigates the streetscapes of PC Bangs as electronic architectural spaces and suggests the urban electronic space of PC Bangs in terms of hypertext space. Then, it looks at the effects of PC Bangs on human bodies which exist as human-machine hybrids or cyborgs in PC Bangs. The paradoxical socio-spatial characteristics of PC Bangs as third, liminal or hybrid spaces between actual and virtual spaces or between human and machine spaces can be explained as follows. Firstly, there appear both nomadic and sedentary landscapes in that people in PC Bangs move in virtual spaces on the one hand, and are static in actual spaces on the other hand. Secondly, both open and closed spaces are shaped in that although PC Bangs act as open or public electronic spaces, they involve invisible social boundaries, forming the gendered space of masculinism. Thirdly, the boundaries of the human body are extended and are shrunk at the same time in that while the sensory boundaries of the body in PC Bangs are extended through electronic networks, its social boundaries are shrunk through the imaginary space of solipsism. Thus and finally, PC Bangs can be characterised not only as social spaces entailing embodied and gendered landscapes, but also as non-places involving the cyborg landscapes of human-machine connections.

Recent environmental issues such as genetically modified organisms, the loss of biodiversity, climate change, and nuclear waste cannot be reduced to a matter of science or society and explained through nature-society dualist approaches because of their complexity and heterogeneity. This paper examines how nature-society dualism has been embedded in science studies and geography and how this dualism can be overcome. Actor-Network Theory as an attempt to overcome this nature-society dualism is appropriate in analysing "strange imbriglio" of biology, politics, technoscience, market, value, ethics and facts that constitute our society by focusing on heterogeneous association, and can contribute to providing a useful framework to solve environmental problems.

This paper is to consider conceptually a formation of food-networks and border-crossing of transnational marriage migrant households on the basis of actor-network theory, and to analyze empirical data on the issues collected by interview with marriage migrant women living around Daegu, S.Korea. Some research results can be argued as follows: First, food can be seen, not as a single material object, but as a multiple and hybrid network of human and nonhuman (material and institutional) actors, in which activities of food cooking and eating are regulated by and (re)construct social relations and placeness of households. Secondly, food-networks in marriage migrant households implement relationships of micro-power (and attachment) in the process of its (re)formation, and hence the food-network, it can be argued, is a field of power in which conflicts and compromising around food cooking and eating are intersecting each others. Thirdly, food-networks in marriage migrant households in both their origin country and in the Korean home are not only affected by macro natural and social environments but also by micro placeness of the households, both of which constitute the food-networks and operate in relations with other actors in the netwroks. Finally, food-networks in marriage migrant households reflect multiple and multi-scalar spatial mobility and placeness of transnational food culture, through which they express topologically 'fluid space' and 'absent presence', in which marriage migrant women can (or cannot) conduct social and cultural border-crossing.

We investigated the distribution and geomorphic development of alluvial fan in Gyeongju City including Cheonbuk area. According to a relative height to a river bed, alluvial fans of this area are divided into Higher surface, Middle surface, and Lower surface. As alluvial fans of Bulguk temple∼Ulsan bay area, the confluent fans in Cheonbuk and Gyeongju areas were formed by the Quaternary climatic change alternating glacial and interglacial stages, and the development of N-S and NW-SE fault lines. The Gyeongju alluvial fan, the largest in Korea, has been provided as the significant space for human activity since the prehistoric age. Bukcheon river formed the Gyeongju alluvial fan had not flowed over during the prehistoric and the ancient times. In contrast with general geomorphic characteristics, many springs in the Gyeongju alluvial fan are located in the middle part of the fan because ground water reaches to the surface. It is supposed that sedimental materials were not sufficiently piled up at lower reach of Bukcheon river due to the large deposits at upper and middle reach of the basin.

Based on a long-term ethnographic study, this paper examines how the propositions and practices for desertification management in Inner Mongolia, China have changed over time. Desertification as an ecological issue cannot simply be treated as a something "natural" or "social," while it is an outcome of the construction made by both human and non-human agents. My research has found that the propositions for desertification management have been involved in the process of defining desertification, particularly by selecting different actors related to the ecological process in this region. Ultimately, the crisis in the inner Mongolia has always been constructed by the ways in which the selected actors and their relationships are differently defined. My study also reveals that although the proposed preventive measures, including afforestation, area protection, and pasturing prohibition, have tried to reconcile the conflicts of interest among the different actors, they have always been faced with certain limitations and failed in dryland management. In this historical context of crisis construction, by introducing a new non-human agent, "the chicken," the project of grassland chicken farming has eventually appeared to be an innovative strategy that can overcome the earlier limitations and coordinate the interests of Mongolian pastoralists who have suffered from economic difficulty.

Critical scholarship has shown itself much more adept at identifying and analyzing the content of religious geopolitics than its impacts or effects. This article suggests ways in which the concept of social performance can be used to more carefully consider the effects of religious geopolitics. Judith Butler's identity-oriented notion of performativity is usually geographers' point of entry into issues of performance. But its strong poststructuralist distrust of agency limits its power among those who question poststructuralism's grounding beliefs. This article illustrates the added utility of other theories of performance-particularly the recent pragmatic, dramaturgical, and non-poststructuralist theorization of social performance by the cultural sociologist Jeffrey Alexander-in evaluating the impact of religious geopolitical action. It does so through the case of a recent, particularly geopolitically laden Mormon General Conference. It concludes, through Butler and Alexander, that this General Conference likely accomplished significant geopolitical work. But it also, mainly through Alexander, argues that this work likely had limited capacity to motivate new or additional geopolitical action. Its power was more to reinforce than transform.

It is well known that, since the 15th century, the amount of soil loss in our country due to change in land use by human has increased more rapidly than ever before. However we cannot answer the question 'How long can the soil persist under the current rates of soil loss?', because it was difficult to quantify the soil production rate. With the advancement of accelerated mass spectrometry, the attempt to quantify rate of soil production and derive soil production function succeeded, and recently it was also applied into the Daegwanryeong Plateau. Here we introduce the principles for quantifying soil production and deriving soil production function using terrestrial cosmogenic nuclides, and then compare the soil production rates from the plateau with soil loss data after the late 20th century, and finally estimate how long the soil can persist. Averaged soil production rate since the Holocene derived from the plateau is revealed as ${\sim}0.05[mm\;yr^{-1}]$, and, however, the recent soil loss rate of intensively used farmlands at the same region is up to sixty times greater than the soil production rate. Thus, if current land use system is maintained, top soils on the cultivated lands over hillslopes especially in upland areas are expected to disappear within several decades at the earliest.

A city is an ordinary space and a place of living that is directly related to our lives. An ordinary space is the total products of culture and the target of cultural representation. An aging residential area of a city reflects the ordinary lives of ordinary people along with its unique history; therefore, this place should not be seen only from an economic and political perspective. The Wausan area is a place that best maintains the characteristics and scenery of an aging urban residential area within Gwangju metropolitan city. Through research into this area, it is possible to discover the meaning and true value of an aging urban residential area such as the close relationship between ordinary culture and placeness, the creation factors and process of placeness of an aging urban residential area, and the authenticity of a particular place. This area is a modern residential area of today's ordinary people, created on a topography of hills and hilly areas along with a historical value of 400 years. It is based on the Gyeongyangyeok of the Joseon period. This place may be described as a space where the dailiness of ordinary people is alive based on its alleys and the unique scenery formed by its alleys and vegetable gardens. The authenticity deduced from such placeness is that an aging urban residential area is a place where communicative and considerate human life and a cultural diversity of an atypical nature are alive, a place where an environment and humans coexist in harmony, and a place where the communal dailiness of residents still exists.
