GIS-based spatial data integration tasks have used exhaustive thematic maps generated from sparsely sampled data or satellite-based exhaustive data. Due to a simplification of reality and error in mapping procedures, such spatial data are usually imperfect and of different accuracy. The objective of this study is to carry out a sensitivity analysis in connection with input topographic data for landslide hazard mapping. Two different types of elevation estimates, elevation spot heights and a DEM from ASTER stereo images are considered. The geostatistical framework of kriging is applied for generating more reliable elevation estimates from both sparse elevation spot heights and exhaustive ASTER-based elevation values. The effects of different accuracy arising from different terrain-related maps on the prediction performance of landslide hazard are illustrated from a case study of Boeun, Korea.

The recent development of PSC girder bridges are mostly dedicated for optimization of self-weight, simplification of girder section for easy construction and minimization of maintenance efforts. Moreover some of those bridges are required as a landmark facility which raises the image of locality and harmony with surroundings. An extradosed bridge is one of the best alternates which not only covers the longer span than PSC box girder and also performs the role of landmark facility with much cheaper cost than cable stayed bridge. Hyundai is carrying out the construction of unique style extradosed bridge which have central suspension system and uniform girder depth named Keong-An grand bridge on the Sungnam-Janghowon Express highway. In this paper, major process of design and construction features of Keong-An bridge is presented.

With the improvement of industrial society, the high quality electrical energy, simplification of operation and maintenance, ensuring reliability are being required Also we request urgently change a $SF_6$ for an environment friendly gas insulation material. In this paper the experiments of breakdown characteristics by pressure and gap change of Imitation-Air in model GIS(Gas Insulated Switchgear) were described. Also assess of breakdown characteristics about Imitation-Air and $SF_6$. It is considered in this paper that the results are fundamental data for electric insulation design of Distribution Power Facilities which will be studied and developed in the future.

The purpose of this study is to research the Korean and Japanese costume systems and to compare both of them on the process of adopting the western-originated costumes. The consequences of this study are as follows. Chosen and Japan started simplifying the traditional clothings, Introducing the western clothings and executed the ordinance prohibitory topknots through reforming costume systems since Port Opening Treaties in 19th centra. Japan performed the reformation of costume system effectively through the grand campaign of social reforming enlightment by Meiji Government. Meanwhile in Korea, there were a continual repetition of adoption and rejection in the reformation of costume systems because of strong cultural self-esteem and competition of foreign Empires. However, western-originated cultural perspectives brought the strong self-devaluated view on their own cultures to both countries. And that's the first cause of substitution of western clothings for ordinary ones in both nations.

In this study, it can be identified that drawing style of cartoon and fashion illustration are mutually linked and interchanged. The common background of drawing style between cartoon and fashion illustration, is as follows; 1. A means of image communication through mass communication 2. Similarities as visual signs 3. The borderless of painting, illustration and cartoon. 4. Usage of common drawing expressions such as deformation, distortion, exaggeration, metaphor, metonymy. Drawing style interchanging between cartoon and fashion illustration, is as follows; 1. Similar to figure and face are contemporary style, similar figure, Anime style and humourous style. 2. Similar to the way of express is focusing on the line, simplification, mixed computer graphics with hand drawing, artistic expression, the way of multimedia.

H-mode or X-mode predominates in marine engines according to the number of cylinder. Generally, H-mode noticeably happen in the engine below 7-cylinder and X-mode remarkably happen above 8-cylinder in the engine operating range. Until now, FEA (Finite Element Analysis) of 3D engine model has been mainly used to estimate the engine vibration but it is very time consuming for simulation and difficult to model simplification. Furthermore, the accuracy of simulation shows a marked difference according to modeling method. Therefore it is very difficult to have contentable result from FEA for beginners and laymen. In this paper, the estimation method based on a test has been suggested to solve the difficulty.

The thesis examines the problems for innovation of export and import conditions and shows the various ways of overcoming them. The alternatives of export and import conditions are as follows. First, the government body including customs service should participate on positive lines for the construction of single window and standardization of the required documents. Second, it is required the development of efficient connection system among exporter and importer, customs service, requirement confirmation agency etc. to contribute the simplification of a operation. Therefore this research is intended to improve understanding of changes for innovation and to contribute in support basis, operation structure, legal and institutional side. Practical implications regarding the innovation of export and import conditions for electronic trade are discussed.

In this paper. the effects of the aspect ratio on the natural frequency of the advanced composite road structures is studied. The advanced composite structures are too difficult for such design engineers for construction and some simple but accurate enough methods are necessary. Some laminate orientations have decreasing values of $D_{16}$, $B_{16}$, $D_{26}$ and $B_{26}$ stiffnesses as the ply number increases. The plate aspect ratio considered is from 1 to 5. Most of the road structures have large aspect ratios, for such cases further simplification is possible by neglecting the effect of the longitudinal moment terms.

The purpose of this is to analyze environment of foreign direct investment and Act in Korea and to find invitation and extension of foreign direct investment into Korea. Investment incentives, simplification of investment procedures, image improvement, increased public relations and investment support services are all factors which can be enhanced in the short term to positively influence investors decision-making in where to invest. Since the enactment of the Foreign Investment Promotion Act in November of 1998, there has been a signification improvement in Korea's investment environment in terms of policies and systems. It is expected that the foreign direct investment environment in Korea will continue to improve through the improvement in political stability, labor-management relations and easing of political tensions between the North and South, in the long term, as well as through improvements in investment incentives, investment procedures and public relations activities, in the short term.

모바일 GIS를 구현하는 방식은 휴대 단말기로 전송되는 지도 데이터의 형식에 따라 벡터(Vector) 기법과 래스터(Raster) 기법으로 나뉜다. 각 기법에 따라 모바일 지도 서비스를 위한 서버 및 클라이언트 구현 방법을 달리 요구한다. 또한, 각각이 서로 다른 측면에서 장단점을 지니고 있다. 본 논문은 이 두 접근 방법을 구현하고 실험을 통해 그 장단점을 비교한다. 전송 성능, 지도 품질 등 다양한 요소를 비교하고 평가한다.
