At present, environmental monitoring of linear infrastructure is based mainly on field sampling. The 'integrated mapping' approach has received only limited attention from field scientists. The increased environmental regulation of corridor targets has required remote sensing research to develop a sensor or technique for targets ranging from 15 m to 100 m in swath width. In an attempt to identify the optimal remote sensing system for linear targets, an overview is provided of the application requirements and the technology currently available. The relative limitation of traditional remote sensing systems in such a linear application is briefly discussed. It is noted that airborne video could provide, in a cost-effective manner, information required for a very narrow and long strip target utilising the narrow view angle and dynamic stereo coverage. The value of this paper is warranted in proposing a new concept of video infrastructure monitoring as a future research direction in the recognition of sensor characteristics and limitations.

This study investigated how appropriate the classification methods based on conventional spectral characteristics are for high resolution imagery. A supervised classification mixing parametric and non-parametric rules, a method in which fuzzy theory is applied to such classification, and an unsupervised method were performed and compared to each other for accuracy. In addition, comparing the result screen-digitized through interpretation to the classification result using spectral characteristics, this study analyzed the conformity of both methods. Although the supervised classification to which fuzzy theory was applied showed the best performance, the application of conventional classification techniques to high resolution imagery had some limitations due to there being too much information unnecessary to classification, shadows, and a lack of spectral information. Consequently, more advanced techniques including integration with other advanced remote sensing technologies, such as lidar, and application of filtering or template techniques, are required to classify land cover/use or to extract useful information from high resolution imagery.

In most countries, public libraries play a role as a knowledge and information hub for local communities, a complex cultural space, and a third place for meetings and communication. Among the work of public libraries for this purpose, the key point is systematic collection development, and the established collection is essential for all knowledge and information services. In particular, local representative libraries must perform legal duties as a comprehensive knowledge information center for metropolitan governments, and develop, preserve, and service specialized collections that are difficult for other public libraries. Therefore, we analyzed the development cases of specialized collections of public libraries in large cities in foreign countries and local representative libraries in Korea, surveyed the degree of awareness of specialized collections for employees of public libraries and the cultural to geography in Gyeongbuk region. Based on the background information, this study proposed the development plan and establishment strategy of the Gyeongbuk Library specialized collection, which was named "Gyeongbuk Knowledge and Cultural Heritage."

Recent studies on development are increasingly focusing on analyzing development discourse and de constructing its institutionalization process in the nation-state. By pushing up the limit of the research on development, these studies particularly emphasize how development is articulated with the nation-state, its governmentality, and various representations. These studies overall consider development a powerful discourse, which invents under-development, mobilizes resources for changing particular space, and institutionalizes modem systems of socio-spatial control at a local scale. In this sense, it is particularly interesting to look at how the nation-state, faced with the deterritorialization of labor and capital, reterritorializes overseas resources and networks for the purpose of development. By problematizing the Overseas Koreans Foundation as a transnational state apparatus, this paper interrogates the way in which its institutionalized practices conjure up the national imagination, ethnic solidarity, and collective allegiance to the homeland in diaspora communities. This paper conclusively reports that the state apparatus circulates the discourse of transnational nationalism in Korean diaspora so as to appropriate their resources and networks for securing foreign currencies and investment in the homeland.

We analyzed two radiocarbon-dated lagoonal sediment cores from Cheonjinho and Ssangho using various biogeochemical methods. As a result, the start times of rice agriculture are estimated to be AD 780 for Cheonjinho and 100 BC for Ssangho. There is a large temporal difference in the beginning of rice agriculture between two study sites even though they are closely located on the coast. This result indicates that pollen records are not sufficient to approximate the start time of rice agriculture accurately. A temporal lag seems to exist between the time when rice agriculture was first introduced and the time when full-scale rice agriculture began in the Yeongdong region, probably because of low agricultural productivity. In both study sites, rice agriculture intensified and slope erosion increased 250 years after full-scale agriculture began. This suggests that intensified rice agriculture resulted in an increased number of inhabitants, settlement expansion to hilly areas, and the consequent deforestation.

GML proposed to offer interoperability of geography information is specifying various dynamic object schema for application in the wireless environment. These GML dynamic object schema supports the expression of moving objects that the position and shape change consecutively over time, so practical use of GML is increased in location-based service that provides various application services based on location information of moving objects. In particular, the conventional query languages about GML have been studied with priority given to the integration of geographic information, the support of spatial operations, and etc. However, it lacks the support for moving objects queries. Therefore, in this paper, we propose the moving objects query language that supports moving objects queries for GML documents by extension of XQuery that is standard in query language. Also, data model, algebra operation and various moving objects operators for the proposed query language are designed, and we apply the proposed query language to tornado government organization system to show that the proposed query language can be used effectively in various location-based service.

This paper is to explore the cross-border interactions and the formation of trans-boundary regional identity in the Swiss-German-French border region. It begins with a brief review of recent studies on 'boundary and border region', in order to gain a insight into the theoretical debates on this theme and to find out ideal types of the cross-border co-operations. And then it deals with the everyday cross-border movements(working, shopping, living) in 'Regio TriRhena', discussing the development of the trans-boundary co-operations in the EuroRegion 'Upper Rhine'. There are several committees to be defined in trans-boundary co-operation on the 'Upper Rhine', with different scopes of action, structured collectively like Russian dolls(Babushka principle). The economic differences between 3 countries trigger massive cross-border movements. This paper attempts to organize these cross-border interactions around Ullman's 3 bases for spatial interaction(complementarity, transferability, intervening opportunity). In conclusion, this paper shows that the elimination of economic obstacles does not suffice to create trans-boundary identity or a trans-border common regional spirit.

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.
