In this research, we propose a path-planning algorithm for an autonomous mobile robot using geographical information, under the condition that the robot moves in unknown environment. All image inputted by camera at every sampling time are analyzed and geographical elements are recognized, and the geographical information is embedded in environmental map. The geographical information was transformed into 1-dimensional evaluation value that expressed the difficulty of movement for the robot. The robot goes toward the goal searching for path that minimizes the evaluation value at every sampling time. Then, the path is updated by integrating the exploited information and the prediction on unexploited environment. We used a sensor fusion method for improving the mobile robot dead reckoning accuracy. The experiment results that confirm the effectiveness of the proposed algorithm on the robot's reaching the goal successfully using geographical information are presented.

This study aims at the suggestion of possibility that a housing density will maintain properly and that an ecological hill housing will recover a rapport with the ground. That is, both residential planning on the hillside and ecological architecture as a concept for development are chosen for study category, and relationship between the hillside and the hill housing is theorized and then propriety is analysed through application of the ecological planning elements. The results of this study are as follows: 1. Now that the hillside is regarded as an idle land that preserves natural environment and maintains ecosystem, it must be developed on the basis of awareness that nature and human beings exist together. 2. Analysis of geographical factors must be advanced because it is inevitable that the development of the hill housing should be performed properly to the geographical characteristics. 3. Planning elements of ecological residential block which are possible for constructing on the hillside can be developed and applied, on the basis of geographical characteristics, by classifying them into two areas; housing estate, building and unit.

본 연구의 목적은 지형요소의 GIS Database 구축을 위한 전산화된 지형분류도 제작방안을 제시하는 것이다. 지형요소 전산화는 지형요소의 분류, 지형요소의 코드화, 범례화, 심볼의 제작, 마지막으로 지도화의 과정을 통하여 완성된다. 지형분류는 지형요소의 공간적 분포와 형태, 지형형성과 발달에 영향을 미치는 자연환경체계와 지형형성기구의 역할을 고려하며, 동적인 지형형성과정과 이 과정을 통해 물질관계를 파악할 수 있도록 하였다. 지형분류도는 1: 25,000 축적에 표현 가능한 지형요소를 나타낼 수 있도록 고려하였다. 지형요소들의 지도화 되었을 때는 시.공간적인 관계를 통해 지형환경체계가 인식되도록 하였다. 지형요소들은 GIS에서 Layer단위로 입력되어야 하기 때문에 Data Feature의 성격을 점.선.면으로 분류하여 지형요소의 형상을 범례로 만들었다. 지형요소 범례는 지형의 형태, 물질 그리고 성인을 고려하여 지형요소를 상징화할 수 있도록 설계하였다.

The purpose of this study is to develop documentation elements that can effectively record urban regeneration projects, focusing on port cities, in line with the historical background of urban regeneration projects. In order to develop recording elements, elements that need to be recorded were derived from eight fields, including geographical information, industrial information, and legal and administrative changes, from the Urban Regeneration Act, Port-related Act, and Urban Regeneration-related research. A Delphi survey was conducted three times targeting 20 experts related to urban regeneration to gather their opinions on elements derived from the Urban Regeneration Act, Port-related Act, and related research, and 32 final elements were derived. The recording elements for each selected area are geographical information(6), immaterial information(4), environmental maintenance(5), industrial and economic primary and secondary industries(2), and industrial and economic tertiary industries(3), changes(6), member participation(4), local legal and administrative systems(2). In addition, the applicability of urban regeneration documentation elements to local government records management experts was verified.

In this study, the basic theory of geomagnetism was introduced and the field data of first order magnetic survey was analyzed to determine geographical distribution of magnetic elements such as Declination(D), Inclination(1), Horizontal Component(H), Vertical Component(Z) and Total Force(F). From this distribution equations, the distribution of geomagnetism of Korean peninsula was examined and the declination was calculated for National Base Maps.

Taking note of growing tendency of academic interests and policy applications with regard to social economy, this study aims to suggest economic geographical agenda for social economy. It is presumed that the orientation of social economy toward pursuing social value will exhibit unique spatial characteristics. Elements containing spatial implications have been identified through a review of hierarchial concepts including social innovation, social economy organization and social enterprise. Three approached are suggested as tools of understanding the spatial context of social economy: spatial characteristics inspiring social entrepreneurship, place-based context of decision-making by social economy organizations, and spaces formulated by interactions between the demand for solving social problems and the supply of economic resources. The investigation of social innovation clusters is required to focus on the differentiated characteristics from normal industrial clusters. It is also suggested that the concept of embeddedness be applied in the search of the essence and elements of social economy's ties with local community.

Most of global citizens in the globalization era want to live peacefully in the symbiotic relationship among each region or locality with its identity. From this perspective, the new regionalist models of development such as new industrial districts, industrial clusters, regional innovation systems, and global city-regions isn't helpful to most of regions because they were developed to increase the global competitiveness of industrial region from a few advanced industrial areas. This study attempts to develop 'regional differential development' as an alternative regional development theory. This theory puts emphasis on the truth that the difference or differential industry between regions in the real world connotes two essential values of development like the symbiosis of global citizens and the regional identity. Regional differential development seeks the development of regional differential industry on the basis of geographical elements with differential advantage, and hence it reviews significantly geographical elements including location, natural environment(landform, soil, climate, etc.), natural resources, population, transportation, culture, and landscape which appear substantially differently among regions. And to realize regional differential development successfully, it is crucial that actors(government, company, related institutions, and regional residents) actively participate and play each complementary role in the relationship of cooperation and conflict. Further study needs to secure the universal validity of this theory through many empirical studies.

Radio navigation aids are very important elements to provide information necessary for safe navigation using radio waves. Recently, the number of radio equipment using radio waves is increasing, and the air frequency interference by adjacent channels is very high. In addition, the use of irregular jamming that threatening radio navigation aids and satellite navigation system frequency is rapidly increasing. Therefore, it is urgent to ensure the safety of air waves. In this paper, we investigated the characteristics and frequency of the domestic navigation system. And we were analyzed the geographical separation standard for implementation of analysis program. Also, we implemented a program for the geographical separation distance analysis that applying international standards and recommended practices.

This study suggests that the contents and methods focusing on the leamer's geographical experience of everyday life and environments, are very effective for teaching and teaming in geography subject matter. The contents have to be selected and structurized from private geographies about their region of everyday life for teaming abstractive and scientific concepts of geography. Scientific concepts of geography, i.e. geographical concepts become 'scope'for selecting the contents and these systematic structure substitutes 'sequence'. The criteria by which selected contents of teaching and teaming based on everyday life may consist of three elements: region as leamer's place for everyday life; concrete experience of the place; and leamer's changing geographical experiences.
