The infinite imagination and variety of material, and freedom of expression are fundamental elements of the comics. However, although the freedom of comics expression is linked with the liberty of speech and press, it's expression is constrained by a public authority and social pressure, self-regulation. This paper explains some problems and desirable freedom of expression thought researches on constraints of comics expression of Korea and Japan.

Map services for cellular phone have problem for implementation, which are the limitation of a screen size. To effectively represent map data on screen of celluar phone, it need a process which translate a detailed map data into less detailed data using map generalization, and it should manipulate zoom in out quickly by leveling the generalized data. However, current spatial indexing methods supporting map generalization do not support all map generalization operations. In this paper, We propose a leveled spatial indexing method, LMG-tree, supporting map generalization and presents the results of performance evaluation.

The purpose of this study is to investigate the relationship between the development of French state and the development of cartography from the sixteenth century to the seventeenth century. For this, firstly, the development of military maps as a means for the defense and expansion of territory was examined. Secondly, the development of overseas maps as an aid for colonial expansion was considered. Thirdly, the development of national maps as a representation of the state was examined. Fourthly, the development of atlas mapping as a means for establishing national consciousness was considered. And finally, the role of maps in state building was discussed.

Chinease-Korean Cultural Map, which is an electronic cultural map that shows Chinese-Korean culture on maps, is planned as the first step to development Asian Electronic Cultural Map. Chinese-Korean have their unique cultural characteristics same as other small tribes. Small tribes shows same typical cultural characteristics of Asian, and that characteristics are very important factors for understanding the whole Asian culture. This paper proposes a logical and standardized development methodology for construction of Electronic Cultural Map. The methodology consists of 6 steps; information analysis, keyword extraction, keyword clustering, map element extraction, prototype design, and map development. We used and evaluated the methodology during prototype design and development steps for the optimal functions. To generate the base maps for Chinese-Korean Cultural Map, we use Google Earth and KML(Keyhole Markup Language) for standardized and easy development.

최근에 군에서 작전계획을 수립하는데 있어서 군사 지도 및 디지털지형정보를 이용한 지형공간 분석 및 판독은 필수적인 요소가 되고 있다. 이에 따라, 군의 작전계획 수립을 지원하는 각종 정보 체계에서는 보다 원활한 지형공간 분석 및 판독을 위해 신속한 지도화면 시현과 다양한 도식들의 제공을 위한 기술이 요구되고 있다. 본 논문은 신속한 지도화면의 시현을 위해 래스터 지도를 타일링하여 3D 평면에 직접 매핑하는 방법을 제안하였고 다양한 도식들을 입체적으로 표현할 수 있게 하였다.

This paper is concentrated on map generalization in digital environment for automated multi-scale map pro-duction using conventional hardcopy maps. Line generalization is urgently required process to prepare small scale digital map database when large scale map databases are available. This paper outlines a new approach to the line generalization when preparing small scale map on the basis of existing large scale distal map. Line generalizations are conducted based on zero-crossing algorithm using six sheets of 115,000 scale YEOSU area which produced by National Geographic Institute. The results are compared to Douglas-Peucker algorithm and manual method. The study gives full details of the data reduction rates and alternatives based on the proposed algorithm.

Although the multi-scale map database should be constructed for the web map services and location-based services, much part of generation process is based on the manual editing. In this study, the map generalization methodology for automatic construction of multi-scale database from the primary data is proposed. Moreover, the generalization methodology is applied to the real map data and the prototype of multi-scale map dataset is generated. Among the generalization operators, selection/elimination, simplification and amalgamation/aggregation is applied in organized manner. The algorithm and parameters for generalization is determined experimentally considering T$\ddot{o}$pfer's radical law, minimum drawable object of map and visual aspect. The target scale level is five(1:1,000, 1:5,000, 1:25,000, 1:100,000, 1:500,000) and for the target data, new address data and digital topographic map is used.

National Geography Institute(NGI, National mapping agency) has been producing national basemap in automated process since middle of 1980's toward the systematic and efficient management of national land. In 1995, Korean government initiated a full-scale implementation of the National Geographic Information System(NGIS) Development Plan. Under the NGIS Development Plan, NGI began to produce digital maps in the scales of 1:1,000, 1:5,000, 1:25,000. However, digital maps of 1:250,000 scale, which are currently used for national land planning, were not included in NCIS Development Plan. Also, the existing laws and specifications related to digital maps of 1:250,000 scale are not clearly defined. It is fully appreciated that data dictionary will be a key element for users and generators of digital maps to rectify the existing problems in digital maps as well as to maximize the application of digital maps. There(ore this study proposed a feature classification system, which defines features that should be represented in digital map of 1:250,000 scale, and data dictionary as well.

A feng-shui map is a kind of map that features such propitious positions as fortune-bringing spots or ideal grave sites. The map is a representation of the most ideal natural terrains in terms of feng-shui perspectives. This study did research on two feng-shui maps registered on some genealogical tables in order to see how the map was drawn up. In addition, the detailed characteristics of landform expressions like the frame of the map, viewpoints, center-oriented mapping, water flow, mountain theories were delved into. The results of the research are as follows: the feng-shui maps for this research used the techniques of double scale and aerial view, described terrains with grave sites in their centers, and enlarged important terrains compared with surroundings for exaggeration purposes. In addition, other vital landforms not observed from grave sites were depicted with viewpoints moved and were represented in fine details. The part of mountain theories had the following points as their main subject matter: geographical locations, overall orientations of mountain ranges, topographical traits, grave seat directions and surrounding terrains.

The purpose of this paper is to propose a data transformation method for visualizing the statistical information based on the grid system which has regular shape and size. Grid is better solution than administrator boundary or census block to check the distribution of the statistical information and be able to use as a spatial unit on the map flexibly. On the other hand, we need the additional process to convert the various statistical information to grid if we use the current method which is areal interpolation. Therefore, this paper proposes the 3 steps to convert the various statistical information to grid. 1)Geocoding the statistical information, 2)Converting the spatial information through the defining the spatial relationship, 3)Attribute transformation considering the data scale measurement. This method applies to the population density of Seoul to convert to the grid. Especially, spatial autocorrelation is performed to check the consistency of grid display if the reference data is different for same statistic information. As a result, both distribution of grid are similar to each other when the population density data which is represented by census block and building is converted to grid. Through the result of implementation, it is demonstrated to be able to perform the consistent data conversion based on the proposed method.
