The purpose of this study is to develop a 3 dimensional spatial planning model (3DSPLAM) for facilities allocation and visual evaluation in improvement planning of rural village. For the model development, this study developed both planning layers and a modelling process for spatial planning of rural villages. The 3DSPLAM generates road networks and village facilities location automatically from built area plan map and digital elevation model generated by geographic information system. The model also simulates 3-dimensional villagescape for visual presentation of the planned results. The 3DSPLAM could be conveniently used for automatic allocation of roads, easy partition of land lots and reasonable locating of facilities. The planned results could be also presented in the stereoscopic models with varied viewing positions and angles.

In this paper, suggested is a hybrid-type visual alignment system to align mask and panel in 3-D space, where mask and panel are to be controlled independently by two individual positioning mechanisms in order to compensate for spatial misalignments. In the hybrid visual alignment system, the below 4-PPR parallel mechanism provides in-plain motions to pattern mask like the other conventional alignment systems while the above 4-RPS parallel mechanism is to move glass panel to achieve a complete spatial alignment. For the control of the hybrid alignment system, first, inverse kinematic solutions for the parallel mechanisms are given to determine the driving distance of each active joint, and also an efficient way to determine the spatial alignment error is developed by exploiting three in-plane cameras.

Spatial light modulators (SLMs) are centrally important devices in volumetric recording, data Processing, Pattern recognition and other optical systems. Various types of reusable SLMs with two-dimensional pixel arrays have been intensively developed. Of these, magneto-optic spatial light modulators (MOSLMs) have advantages of high switching speed, robustness, nonvolatility, and radioactive resistance. In this article, we review recent development work on MOSLMs, mainly in relation to our own studies.

This study is on the organizational principles of Chinese traditional houses. It has been assumed that a common cultural background did influence dwelling construction in most areas of China, some specific concepts are used to build a connection between the culture and architecture. There are four aspects of cultural influence being explored: traditional concept of space by the philosophical influence, religious influence, the Feng Shut method, and traditional system of family organization. The influence of the Chinese culture on dwelling architecture is predominant. Housing types from different areas of China, despite their different physical appearance, have similar spatial concepts. This cultural influence was due to the historic development of the Chinese empire. The organizational principles of Chinese dwelling architecture determined by its own cultural background have five major invariable norms. They are as follows: 1. Internal and enclosed spatial organization. 2. Grouping of buildings around axes. 3. Spatial organization and extension by courtyard. 4. Spatial expansion by adding units. 5. Hierarchical organization of space.

The purpose of this study is to the spatial composition of charnel facilities. The study method is as follow: First, To Examine existent research material about charnel house. Second, To Investigate controversial point of equipment and development direction through research the case of cremated human remains deposit rooms in 12 charnel houses constructed since 1990. So, to propose the planning direction of spatial composition based on the analysis results and utilize to basis data that is necessary in research of same kind hereafter.

In order to present a space in details, it is indispensable to acquire 3D shape and texture simultaneously from the same platform. 3D shape is acquired by Laser Scanner as point cloud data, and texture is acquired by CCD sensor. Positioning data is acquired by IMU (Inertial Measurement Unit). All the sensors and equipments are assembled on a hand-trolley. In this research, a method of integrating the 3D shape and texture for automated construction of Digital Surface Model is developed. This Digital Surface Model is applied for efficient feature extraction. More detailed extraction is possible , because 3D Digital Surface Model has both 3D shape and texture information.

The relationship between innovation policies and locational competitiveness has emerged as an important area in the analysis of economic development, reflecting both the centralisation and decentralisation of globalising economic activities. The underlying spatial and institutional components are subject to a pattern of cumulative causation in which strategic interventions of policy actors exercise a decisive role in shaping competitive advantages, while promoting interactions with local and foreign partners both from the private and public sectors. The Singaporean development experience illustrated these strategic interdependencies of innovation policies and locational competitiveness. Based on her role as a manufacturing and service hub, Singapore is viewed as an infrastructural nodal point which is interconnected to global production networks. Paralleling efforts in the domain of technological innovation, Singapore's policies for locational competitiveness aim at an adaptive harmonisation of the needs of international investors with local developmental objectives. This orientation characterises also current efforts in promoting Singapore as a knowledge agglomeration with a distinct science base, expanding R&D operations and an innovation-driven pattern of economic development. In conclusion, the locational rationale of Singapore's innovation policies provides lessons for dealing with the spatial and institutional implications of technological globalisation.

Although sustainable development of a city should in theory be based on updated spatial information like land cover/use changes, in practice there are no effective tools to get such information. However the development of satellite and sensor technologies has increased the supply of high resolution satellite data, allowing cost-effective, multi-temporal monitoring. Especially KOMPSAT-1(KOrea Multi-Purpose SATellite) acquired a large number of images of the whole Korean peninsula and covering some large cities a number of times. In this study land-use patterns and trends of Daejeon from the year 2000 to the year 2003 will be considered using land use maps which are generated by manual interpretation of multi-temporal KOMPSAT EOC imagery and to show the possibility of using high resolution satellite remote sensing data for urban analysis.

Although the strategies and experiences of GIS leading countries are considered for the implementation of NGIS-Development in Korea, the western european nations cases are not analysed. Based on this study focused on German approaches to establish and implement the construction of national geospatial data framework. The goals, construction strategies and contexts of german national framework data, it called authoritative topographic-cartographic information system(ATKIS) in germany, are presented in detail. As a result, some lessons are suggested that can be learned by german approaches. Because we are now standing on the phase of "A Second Master Plan for National Geographic Information System", the german approach can be very for the development of the national framework database in Korea.

In order to support effective decision-makings related to greenery planning, this study construct a fundamental database about greenery information for Seoul metropolitan area using GIS and Remote Sensing. Greenery evaluation index consists of ecological/ environmental, utilization, social condition value which are used to determine the development priority of undevelopment parks. These indexes will also be utilized for the green area conservation classification for Seoul metropolitan area. This study is a part of previous project called "Management Policy of the Total Amout of Greenery", which was conducted in Seoul Development Institute.Institute.
