It is generally found that geography majors' progression in society has a very limited scope in Korea and this is one of the causes of lessening geographers' job market. As an attempt to draw a solution to this problem, this paper, by a close examination of the French case, tries to discuss the possibility of geographers' participation in the public sector. Geographers' participation in political and social issues has long history. They acted as providers of geographical knowledge on human and physical features of the world and also as counsellors for effective administration and politics. French geographers evaluate that it is the characteristics of geography that enable geographers to progress into the public sector. They also perceive that such fields as regional development, environment, economy, tourism, international politics are possible ones for geographers. Some implications can be drawn from this case study to extend geographers' participation in the pubic sector in Korea; it is required to sustain open mind to every field of social sciences, to improve specialized as well as generalized knowledge on geographical features, and to provide practical knowledge on spatial analysis and management.

The purpose of this study was to understand the geographical and environmental distribution of wild animals in Baekdudaegan region using field survey and GIS data. Crucial factors were selected and analyzed to understand the distributional characteristics of wild animals (7 species in 6 families) and rare endemic plants (14 species in 11 families). These crucial factors include stand factors (forest type, DBH class, and crown density), soil factors (bed rock, soil texture, and organic matter), geographical factors (elevation, slope, aspect) and climatic factors (temperature, rain fall, humidity). Finally, 10 factors were selected by statistical analysis and categorized for analyzing geographical and environmental features. Four families such as Muridae, Sciuridae, Suidae and Talpidea in wild animal showed the similar habitat characteristics with the 10 factors.

Seven genetic lines of Bupleurum falcatum L. from different geographical regions were analysed for saikosaponin contents and chromosomal numbers. The somatic chromosome numbers of B. falcatum originated from Euisong, Iri, Milyang, Sangnam, Taejon, and Youngchon were 2n=20 while Mishimasaiko showed 2n=26. However, chromosome features were different in plants grown in different geographical regions. Generally, Korean lines had higher saikosaponin contents than Mishimasaiko which is Japanese and Sangnam lines had highest saikosaponin contents compared to other tested lines.

This study is aimed to reflect the current status survey, analysis and response of 10 railway stations using geographical names in one of 19 stations located on Gyeongbu, Honam and Chungbuk line. Most railway stations in the study have shown normal images that are close to the standard type by selecting similar building materials rather than reflecting geographical features. Aside from the shape of the traditional Korean house in Cheongju, almost all newly constructed stations tend to incorporate light gray plating material on their modern exterior to produce Family look design as a railroad station. According to a survey of the sensitivity of the station's name, Osong Station was 73.6 percent, Gyeryong Station 67.3 percent, Heukseok-ri Station was 64.5 percent, Shintan-jin 62.6 percent, and Yeonsan Station 57 percent, more than half. Therefore, the results of the five stations were presented as a calculation and proposed design release focusing on the facades of each station. Each of these stations suggested a way to express the facade design image, considering the railway operation status of Korea Railroad, the area of the station and other surroundings.

A analysis on the spatial features is required for exploratory spatial data analysis of information about space location(population ecological factor, social ecological factor) to manage the store factors, the service industry, etc. Therefore, the purpose of this study is to provide correlation analysis method between the types of service trade using dependence between spatial objects on the geographical space and statistical correlation and to analyze the spatial features through the deduction of correlation analysis between the types of the neighborhood trade area.

The purposes of this study are to identify many implications of commuting regional type according to the features of foreigner commuting. Research on the pattern of distribution of foreigners has been very simple and limited because foreigners usually lived together in a specific area, and their workplace often tended to be their residence. However they currently live dispersed more Widely, and their job and housing increasingly tend to be mismatched. This study divided areas inhabited by foreigners into general one characterized by job-housing match and exceptional one characterized by job-housing mismatch, and then examined the features of foreigner commuting. General commute type showed a high rate of intra area commute and foreign workers' universal features. Inflow commute type showing high E/R ratio. In these areas, outflow commuters had a short journey to work while inflow commuters had relatively a long journey to work, and professionals accounted for a high proportion of employees. Outflow commute type showing low E/R ratio. In these areas, outflow commuters had a long journey to work while inflow commuters had a relatively short journey to work. The composition ratio of three commute types was different according to nationality and visa type.

In this paper, we propose Media CIS system architecture which provides geographical information of geo-features in video sequences by using 3D geographical database and GPS-related data resulted from 4S-Van. We introduce a novel interoperable geographical data service concept, so-called, Virtual World Mapping (VWA) that can map 3D graphic world with real-world video to provide geographical information. Our proposed method can easily retrieve geographical information and attributes to reconstruct 3D virtual space according to certain frame in video sequences. Our proposed system architecture also has an advantage that can provide geographical information service with video stream without any image processing procedures. In addition to, describing the details of our components, we present a Media GIS web service system by using GeoVideo Server, which performs VWM technique.

It's been confirmed that Ondal Cave has gone through secondary cave formations. The comprehensive geological and regional characteristics of Ondal Cave have been investigated. According to the said investigation, geographical features need to be properly used in considerations for natural characteristics by area, and a passage should be developed.

Modern society is the age of a high state of information and demands more effective land information. Moreover, because the use of land in Korea is intensive, Korea requires more synthetic and systematic geographical information for which the digitizing of terrain is prerequisite. This study aims at development of the data structure which is suitable to the digitizing of terrain for Geographical Information System(GIS). Regular grid has been used generally in Digital Terrain Model(DTM), for it is easy to manipulate. But regular cannot reflect well the terrain surface features. In the meantime, Triangulated Irregular Network(TIN) has complex data structure, but it can describe well terrain surface features and is useful in various applications. In this paper the method which constructs effective DTM by improving TIN has been researched.

In this paper, we propose a novel position accuracy enhancement method of a low-end GPS using digital map information. The latest digital map has various kinds of information on geographical features. The proposed method uses position information of lane marks among the geographical features. We define the position information of lane marks as the reference points. The position information of a low-end GPS acquired for a period of time is defined as the source points. In the proposed method, rotation and translation matrices between the reference and the source points are calculated by using an Iterative Closest Point(ICP) algorithm. The source points are transformed by the obtained rotation and translation matrices. Finally, the transformed source points are projected on the reference points. Through these processes, the position accuracy of a low-end GPS is ultimately enhanced. To verify the proposed method, the various real experimental results are presented.
