Landslide damage comprise most part of the damages from the earthquake and it only causes the damage to lives and structures directly but also cease the operation of social system by road or lifeline failure. For these reasons hazard assesment on the landslides has been recognized very important. And hazard maps have been used to visualize the hazard of the landslide. In this study as first step for application of hazard map to domestic cases hazard maps are made for the Ul-Joo Ul-san Korea, Where the Yan-san faults are located. For building hazard maps the degree of hazard are evaluated based on Newmark displacement and the resulting maps are constructed by GIS technique. In hazard assesment maximum ground acceleration obtained from attenuation equation of wave propagation and design earthquake acceleration suggested by Ministry of construction are used for acceleration term. Hazard maps are made by GIS programs Arc/Info and Arc/View based on the digital maps and data from lab tests and elastic wave surveys The maps show the possible landslide regions significantly and the displacements of slide are proportional to the slope angles.

Using the idea of degree of openness and degree of nonopenness, Coker and Demirci [5] defined intuitionistic fuzzy topological spaces in Sostak's sense as a generalization of smooth topological spaces and intuitionistic fuzzy topological spaces. M. N. Mukherjee and S. P. Sinha [10] introduced the concept of fuzzy irresolute maps on Chang's fuzzy topological spaces. In this paper, we introduce the concepts of fuzzy (r,s)-irresolute, fuzzy (r,s)-presemiopen, fuzzy almost (r,s)-open, and fuzzy weakly (r,s)-continuous maps on intuitionistic fuzzy topological spaces in Sostak's sense. Using the notions of fuzzy (r,s)-neighborhoods and fuzzy (r,s)-semineighborhoods of a given intuitionistic fuzzy points, characterizations of fuzzy (r,s)-irresolute maps are displayed. The relations among fuzzy (r,s)-irresolute maps, fuzzy (r,s)-continuous maps, fuzzy almost (r,s)-continuous maps, and fuzzy weakly (r,s)-cotinuous maps are discussed.

This system is capable of obtaining quantitative information from images using natural features on the ortho-image maps that correspond with those from topographical maps. However, the qualitative information can also be obtained because because of the excellent visibility of ortho-image maps. There are plenty of promise for the use of ortho-image maps in the next generation topographic technology because of its wider applicability within the field. In keeping with the cutting edge, we produced ortho-image maps by scanning a specified area in narrow sections using the PKNU 2: a multispectral digital aerial photographing system made by ourselves. We evaluated the precision of the ortho-image maps, and performed an evaluation of the PKNU 2 system's capacity to improve the equipment of the PKNU 2. Ortho-image maps were made using Ground Control Points (GCPs) which were obtained from digital maps and aerial photographs of the PKNU 2. Thus, we demonstrated that it was possible to produce the ortho-image maps, which has a good constant level rate of less than 1m. The PKNU 2 system needs to be improving in the sensitivity of level maintenance equipment in the evaluation in terms of performance. It is thus required to survey the GCPs precisely for an accurate study.

FRBR 모델에서는 서지 요소와 관계를 중심으로 ER 모델링 방식을 제공하고 있지만, 단지 구조적 프레임워크로서 FRBR 모델을 효율적으로 구현할 수 있는 도구가 필요하다. 본 연구에서는 Topic Maps를 이용하여 FRBR 모델을 구현하는 방법을 제시한다. Topic Maps 기반의 FRBR 모델 구현의 유효성을 실증적으로 보이기 위하여, 명성황후라는 주제와 관련된 MARC 데이터를 추출하여 FRBR 모델을 설계하였고, Topic Maps를 이용하여 이를 구현하였다. 연구 결과, FRBR의 entity-relation과 Topic Maps의 topic-association이 개념적으로 동일하기 때문에 FRBR 모델 개발의 적합함을 알 수 있었다. FRBR 구조는 Topic Maps 패러다임과 그대로 일치하기 때문에 FRBR 모델은 Topic Maps로 구현함이 바람직하다.

The purpose of this study is to investigate significant differences of structural knowledges among the groups(high, middle, low) when the 6th grade subjects structured the concepts of the plane figures, triangle and quadrangle, by concept maps, and to analyse the features of concept maps according to hierarchy. For this purpose, the following two research contents were investigated： 1. Investigating significant differences of structural knowledge in the concepts of the plane figures using concept maps among the groups(high, middle, low). 2. Analysing the features of concept maps according to hierarchy. The structural knowledges represented on the concept maps of triangle and quadrangle which were drawn by the subjects were analysed by propositions, hierarchies, and cross-links. Subject-self Reports about how to make the concept maps were used to analyse the features of concept maps according to hierarchy. The conclusions drawn from the results were as fellows： First, there were significant differences among the groups in proposition links. Second, there wasn't my significant difference among the groups in hierarchy. Third, there were significant differences among the groups in cross-links, and Fourth, the results of analysing the concept maps by hierarchy showed that there were differences among the individuals in constructing the knowledges.

본 연구는 조선 후기 고령현을 그린 군현지도와 지리지의 부도(이하 '군현지도')를 계열별로 내용과 고지명을 비교하였고, "대동여지도"와의 연관성을 분석하였다. 23점의 고령현 군현지도들은 회화식지도 8점, 1리 방안지도와 20리 방안지도가 각 4점, 지방지도 5점, 분류 미상인 지도 2점로 구분되었다. 계열별 특징을 보면 회화식지도 계열의 경우 산과 하천을 풍수 형국으로 해석하여, 산줄기가 고령현의 서쪽에서 동쪽의 낙동강으로 이어지는 형태로 묘사하였고, 하천도 이와 상응하여 서쪽에서 발원하여 동으로 유입하는 형태로 그렸다. 1리 방안지도 계열에서는 지도의 배치를 서쪽을 위로 하여 그렸으며, 낙동강을 지도의 아래에 배치하였다. 고령현이 역사적으로 내륙으로 이어지는 교통의 요지로서, 이를 현장감있게 표현한 결과로 사료된다. 20리 방안지도는 다른 지도와는 달리 낙동강의 일부만이 묘사되어 있다. 이는 당시 낙동강변의 일부 지역이 다른 고을에 속하였기 때문이다. 다른 지도에 비해 간결하고 사실적으로 표현하였고, 도로망등을 통해 인접한 고을과의 연결성을 강조하고 있다. 지방지도 계열의 경우 지도 구도는 1리 방안지도와 유사하여 서쪽을 지도 위에 표현하였다. 특히 초계와의 경계를 산줄기로 뚜렷하게 표현하여 지리적 소통이 약함을 표현하였고, 대신 지도의 우측인 북쪽을 열린 공간으로 묘사하였다. 지도별 수록 지명을 보면 회화식 지도와 지방 지도의 경우 읍치 관련 지명들이 많다. 1리 방안지도의 경우 봉수 관련 지명과 험로 등의 지명이 비교적 상세하다. 20리 방안지도의 경우 수록 지명수는 적으나 이웃 고을과의 연결성을 파악할 수 있는 산지 지명을 많이 수록하였다. "대동여지도"와 이들 군현지도를 비교하여 보았을때 20리 방안지도와 가장 가까우나 일부 지명에서 새로운 내용이 수록되어 있다. 이들 내용은 "대동여지도"가 제작되면서 이용된 자료를 추적하는 근거가 될 수 있다.

Floods represent extreme hydrological phenomena that affect populations, environment, social, political, and ecological systems. After the catastrophic floods that have hit Europe and the World in recent decades, the flood problem has become more current. At the EU level, a legal framework has been put in place with the entry into force of Directive 2007/60/EC on Flood Risk Assessment and Management (Flood Directive). Two years after the entry into force of the Floods Directive, Bosnia and Herzegovina (B&H), has adopted a Regulation on the types and content of water protection plans, which takes key steps and activities under the Floods Directive. The "Methodology for developing flood hazard and risk maps" (Methodology) was developed for the territory of Bosnia and Herzegovina, following the methodology used in the majority of EU member states, but with certain modifications to the country's characteristics. Accordingly, activities for the preparation of the Preliminary Flood Risk Assessment for each river basin district were completed in 2015 for the territory of Bosnia and Herzegovina. Activities on the production of hazard maps and flood risk maps are in progress. The results of probable climate change impact model forecasts should be included in the preparation of the Flood Risk Management Plans, which is the subsequent phase of implementing the Flood Directive. By the foregoing, the paper will give an example of the development of the hydrodynamic model of the Zujevina River, as well as the development of hazard and risk maps. Hazard and risk maps have been prepared for medium probability floods of 1/100 as well as for high probability floods of 1/20. The results of LiDAR (Light Detection and Ranging) recording were used to create a digital terrain model (DMR). It was noticed that there are big differences between the flood maps obtained by recording LiDAR techniques in relation to the previous flood maps obtained using georeferenced topographic maps. Particular attention is given to explaining the Methodology applied in Bosnia and Herzegovina.

This study proposed a procedure to improve the error defection of attached cadastral maps using digital map data. In addition, this study also provided the direction for the accuracy improvement of attached cadastral maps by comparing analysis methods. - such as centroid, Lee Sallee shape index, and area index. The analysis is performed as follows. First, by using centroid measurement, the center point of cadastral maps and attached cadastral maps are compared. Secondly by using Lee Sallee shape measurement, the location accuracy of range area is investigated. Thirdly, by using area measurement, the range area within allowable error scope is verified. Based on analysis, the discrepancy between cadastral maps and the attacked cadastral maps are detected as follows; 98.2% from Lee Sallee shape index, 41.8% from centroid, 15.4% from area index in the whole error.
