This study aims to elucidate features of the geography assessment of France in which geography has a high status in school curriculum. The main data for analysing are the geography examinations(1999-2013) of the Baccalaur$\acute{e}$at. In terms of objectives of the assessment, the exams put emphasis on promoting cultural knowledges of students and developing their competences in graphic languages. In terms of formal aspect, the exams take a simple layouts to raise a readability, use variable test tools, especially an essay and a 'croquis'. They also emphasize students self-directedly constructing and representing geography knowledges and their inquiry abilities with geography materials. In terms of contents aspect, the exams mainly cover subjects of political-economic geography, particularly a spatial organization, a development inequality and the world powers in global contexts or macro spatial scales. One of a distinguishing characteristics of Baccalaur$\acute{e}$at's History-Geography examinations is that it designs to keep balance between two parties; history and geography.

21세기 지식정보화사회로 접어들어 GIS가 부각됨에 따라 GIS의 활성화를 위한 기본지리 정보에 대한 중요성이 대두되고 있다. 기본지리정보를 관리 감독하는 국토지리정보원에서는 2000년부터 기본지리정보구축에 관한 연구 등을 수행하여, 기본지리정보의 범위 선정과 데이터모델 표준화가 이루어 졌으며, 기본지리정보 유통과 구축에 필요한 생산사양이 이루어짐에 따라 기본지리정보의 품질 및 활용성에 대한 검토가 필요한 실정이다. 본 연구에서는 시설물분야 기본지리정보 생산사양에 따른 기본지리정보를 3단계에 걸쳐 구축하였으며 기 구축된 교통, 수자원, 행정경계 기본지리정보와 통합하여 활용성 평가를 수행하였다.

지리정보시스템에 대한 응용분야가 확대되면서 지리정보시스템의 기반이 되는 데이터베이스의 성능에 대한 정확한 평가가 중요하게 인식된다. 이때 지리정보시스템의 기반이 되는 데이터베이스는 일반적인 데이터베이스와는 달리 공간 질의와 비공간 질의가 동시에 처리될 수 있어야 하므로 이를 위한 효율적인 색인 구성이 요구되며 이에 대한 성능의 명가가 특별히 중요하다. 본 논문에서는 주기억 데이터베이스 기반의 지리정보시스템에 적합하도록 비공간 색인과 공간 색인을 별도로 두는 이중 색인 구성을 제안하고 실제 색인이 지리정보시스템에 적용되었을 때 그에 이 시스템에 대한 성능을 평가하였다. 실험을 통친 색인에 따른 데이터베이스의 성능비교도 함께 측정하였다. 지리정보시스템을 위한 주기억 데이터베이스에 T-tree와 MR-tree가 비공간 및 공간색인을 위해 적용되었을 때 데이터가 증가하여도 질의에 대한 속도가 거의 변화가 없는 우수한 성능을 보여주는 것을 확인할 수 있었다.

Land suitability assessment is the procedure that assesses development, agriculture or conservation suitability of land according to such criteria as soil, location and usability. But there are many problems to execute land assessment by law. Problems include inadequate basic data, lack of linkage with the spatial planning system, and inefficiency in operation. The purpose of this study is to improve methods of land suitability assessment as a sustainable land use management tool using case study. In this study, land suitability assessment will be executed through GIS. On the basis of the results of this case study, practical and institutional problems are described, and technical solutions are suggested.

오늘날 우리사회에서는 유비쿼터스를 비롯한 정보기술의 급격한 발전에 따라 GIS를 통하여 누구나 일장 속에서 직접 지리정보를 활용할 수 있게 되면서 양질의 지리정보에 대하여 관심을 보이는 편이다. 본 연구에서 다루고자하는 지리정보는 일반시민의 생활과 가장 밀접하고 친숙한 형태의 정보 중 하나이며, 정보로서의 활용도가 매우 높다. 하지만 아직까지 지리정보 데이터베이스 서비스 품질 평가에 주안점을 둔 평가모델이나 평가차원을 도출해보려는 시도에 대한 선행연구가제대로 된 적이 없다. 이에 본 연구에서는 지리정보 데이터베이스 서비스 경우에 서비스품질에 핵심적인 속성들이 무엇인지, 고객만족에 영향을 미치는 가장 중요한 데이터베이스 서비스 품질속성은 무엇인지 알아보고자 한다. 또한 고객의 만족을 실현할 수 있기 위해서는 데이터베이스 서비스 품질속성들이 각각 어떤 수준으로 제공되어야 할 것인가 라는 문제를 컨조인트 분석을 통해 해결해 보고자 한다.

The purpose of this study is to investigate if there is any regional distribution difference in the frequency of geographical location's name mentioned on the SAT Korean geography test. The reviewed items were used for geography subject test in Korean SAT exam in between 2005 and 2015. Researchers analyzed how often a location had been mentioned in the form of maps, captions, and graphs in the national college entrance exam for 11 years. The result indicated that 42% out of the 220 items were using map and about 33% of them represented a specific region. Especially, items related with climate, industries, and local area section contained a specific area information more frequently than others. Moreover, there were 76 cities mentioned in geography subject test on Korean SAT exam during 11 years and 25 places among them were referred to more than three times. The most frequently appeared city was Seoul followed by Incheon, Daegu, Busan, Gangneung, and Jeju and this result shows that there were some regional bias in geography test on the SAT Korean exam.

This paper designs and implements the management system that can calibrate the contamination vulnerability of the ground water, using an object oriented data model. Geographic-objects are specified by features extracted from an applicable geographic domain, and geographic-fields are defined by chemical factors extracted from each driven water. To show the topological relationships among the geographic-objects and the geographic-fields, this paper attach the weight and the ratio of the drastic model to chemical factors represented on the land use digital map and the ground water digital map. The geographic feature class, administrative boundary class, land use class and driven water class consist of a class composition hierarchy for evaluating the convenient contamination vulnerability calibration with spatial relationships among the well objects. Therefore, this management system for evaluating the contamination vulnerability can also contribute to the application of other natural environments.

This paper is about to implement a system for ground water safety evaluation. Since ground water quality is affected from the contamination source of surface water, one can estimate the magnitude of affection and the source themselves. This paper suggests a method to evaluate the spatial relationship of ground water and its contamination sources, using“contain”and“distance”operators in GIS. The research area is the Kunsan City in Chonbuk province, and are 75th wells those are located between the 4th alluvium land types. The results of measured chemical factors and results of related evaluation of these wells are stored and represented in ZEUS 2000 GIS DBMS, and an interface for searching and studying, is implemented by using ZEUS/SQLX, ZEUS/COM, and Visual Basic 6.0 programming languages. After this research, the spatial relationship between hydro-geological geo-objects and ground water is verified and a efficient evaluation system using GIS is suggested. It is the topic of further study that tries to calibrate the suggested evaluation model by applying it to wider area.
