The purpose of this study is to examine the spatial distributional characteristics of industries among the Korean cities and to conduct industry classification using the findings. For this purpose, 82 cities in Korea are investigated with respect to 15 industrial sectors. In the analysis, concentration of and association between industries are recognized using both geographic and non-geographic measures. In order to measure concentration and association, locational Gini coefficient, Moran's I, correlation coefficient, and bivatiate Moran are used and 15 industrial sectors are classified based on these estimates. The findings reveal that the chemical sector shows strong geographic and non-geographic concentrations while the assembly, machinery and electronics sector only shows a strong geographic concentration. Printing and publishing, wholesale, and business services show a strong non-geographic association with other sectors. The remaining ten sectors show no explicit distribution patterns among cities. This study contributes to providing the methodology that analyzes the spatial distribution patterns of industries in a comprehensive way and is able to provide useful information in implementing industrial location policies including industrial clusters.

Recently both the importance and the interests of field-experience learning have kept increasing since the Education of Ministry encourages students to take a field-experience learning with the self-driven and creative education as the main issue in the 7th revised education curriculum in 2009. As the importance of field-experience learning goes up continuously, not only the release of its related mobile applications is increasing, but also a variety of researches for supporting the field-experience learning are ongoing. In this research we perform two things. First, we define the basic concept of authoring tool for which support the field-experience learning based on its characteristics and user requirements analysis. We confirmed that the authoring tool for the field-experience learning has to 1) support all activities that happen in pre-field, field-experience and post-field phases, 2) be possible to write the location-based field work, 3) have the authoring function which reflects the characteristics of curriculum such as history, science and geography, etc. that the field learning can be realized, 4) be designed as the structure that the results of inquiring activity after the field experience activity can be reused. Second, we create a conceptual design after confirming the authoring tool.

Focusing on 'growing together' strategies through horizontal fiscal equalization systems, this and subsequent papers aim to suggest regional co-development strategies in which conflicts between the Seoul Metropolitan Area(SMA) and the non-SMA can be efficiently alleviated. Regarding the socio-economic relationships between the SMA and the non-SMA, there are two contradictory perspectives. One perspective is that the SMA grows at the expense of the non-SMA. The other perspective is that non-SMA's economy is somehow entirely dependent on the economic activities occurring within the SMA, which is the opposite of the former perspective. There are various forms of collaboration among local or regional governments, but the most radical solutions involve the establishment of new regional development financing method at the practical level. This paper suggests that horizontal fiscal equalization not yet introduced between same level subgovernments need to be institutionalized to promote the growing together between the SMA and the rest region of Korea.

It is usual for the officially land price of agricultural field parcels to be determined by real estate appraisers's experienced knowledge and intuition without considering quantitatively physical factors that directly influence agricultural productivity. Solar radiation is the most important predictor of agricultural productivity. GIS based simulation techniques were used to evaluate correlation between the officially land price and solar radiation for agricultural field parcels. The results show that officially land price shows random distribution patterns in relation to solar radiation, which proves that officially land price for agricultural field does not reflect agricultural productivity. It is anticipated that this research output could be used as a valuable reference to support more scientific and objective decision-making in the official pricing process of agricultural field parcels.

The antebellum American South has been characterized by the lingering backward images of plantation, slaves and cotton. The South specializing in the cotton cultivation is compared with the manufacturing East and the breadbasket Midwest. Douglass North who examined the interregional trade assumed that the South up until 1860 relied on the Midwest for the foodstuffs. Statistical and literary evidence, however, disputes the North's model, showing instead that the southern region attained self-sufficiency in foodstuffs at least in the late 1830s or early 1840s. The South's food self-sufficiency is attributable, to a greater extent, to the region-wide environmental movement of scientific agriculture launched to address the aggravating soil problems from cotton monoculture. Diversification and crop rotation lied in the center of the new regime. The new agricultural system combining com, cotton and cowpea ensured the procurement of hoecake, hog meat, and cotton. The most significant outcome of the good farming regime, however, was the enhanced environmental consciousness which came to prevail the best farmer's reckless rush for profit maximization.

To apply the real-time kinematic GPS surveying technique, this research has tried to obtain the TOKYO datum first from the continuous reference stations distributed all over the country. Then, analysis of the geography of a coastal area including both of land and sea has been carried out by the post-processed continuous kinematic GPS technique and the real-time kinematic GPS surveying technique. After considering the initial conditions and measuring time zone for real-time kinematic GPS, post-processed and the real-time kinematic GPS measurements have been carried out. A new system has been proposed to store measured data by using a program developed to store GPS data in real time and to monitor the satellite condition through controller simultaneously. The accuracy of GPS data acquired in real time was as good as that acquired by post processing. It is expected that it will be useful for the analysis of coastal geographic characteristics because DTM can be also constructed for the harbor reclamation, the dredging and the variation of soil movement in a river.

Climate change and large-scale human interference increase flow instability due to changes in watershed flow and sediment transport patterns. There are local problems in solving problems related to sediments, namely the existence of specific problems at specific sites or areas, and the resolution of these problems is limited to short-term and regional, resulting in other temporal and spatial influences and impacts. Therefore, this study intends to introduce and propose a conceptual framework for comprehensive sediment management in terms of watershed scale for solving problems related to sediments in watersheds. In the watershed scale, comprehensive sediment management should be done, to do this, a comprehensive understanding of the movements of sediments accompanied by cooperation with science-policy-operation-residents should be given priority.

Using monthly AVHRR-NDVI composite images, global vector data and statistical information, land cover change patterns in Asia during the major growing season (June, July and August) were analyzed for each country. Specifically, explanations on NDVI changes were developed at a regional scale emphasizing human impacts on ground vegetation. The annual mean change in each country showed NDVI-gain trends in high latitude areas and some parts of eastern China and northern/western India. On the contrary, NDVI-loss trends were distinctive in Japan, Korea, some parts of southeastern China, Vietnam, Laos, Cambodia, Thailand, Myanmar and some parts in southwestern/eastern India. These patterns largely coincided with socio-economic information reflected by human behavior. The NDVI change trends showed significant correlation with forest area changes. Also, a multiple regression model showed that the NDVI change patterns were significantly dependent on the changes in forest area and total population.

Two primary objectives of this study were to determine important personal factors in performing cognitive distance mapping, and to understand how human's cognitive distance mapping capabilities were influenced by reference and subjects' locations using Global Positioning System (GPS). Undergraduate and graduate students at the University of Kansas, USA were interviewed and surveyed throughout the campus area giving them a paper-and-pencil test. Study results showed that females had more accurate cognitive mapping capability than males regardless of ethnic background and academic levels. Generally, subjects with longer affiliation with the university, higher ages and academic levels had less variability in their mapping accuracy. Subjects tended to more accurately map the target locations closer to the reference points than those located farther away, and subjects who were closer to a reference point performed their distance mapping better than those farther away. A correlation analysis reported that male subjects used reference-to-target and subject-to-reference distances more sensitively than females to estimate the locations of the targets. This result indicates that males might have used the reference point-based map scale more strenuously than females.

The purpose of this study is to analyze the relation between regional identity and national identity in a regional textbook in Korea. In geography education, regional textbooks are curriculum materials which represent regional identity based on territorial difference from other regions. In local curriculum level, the harmony between national unity and regional identity is to be pursued as educational objective. However, this harmony appears to be distorted in the school textbook in Je-Ju Province, a case region. For example, Confucian cultural landscapes are represented as otherness in regional discourses, but togetherness in the regional textbook. Also, the regional textbook implies that the boundary of external territorialization is mainly not regions but nations, and it seems to intend that leasers get a sense of place towards their region as periphery of nation. Therefore, we argue that regional identity, which must be stressed in a regional textbook, is marginalized in a case region.
