Recently, tthe general users' demand on utilizing spatial information and the establishment of national spatial data such as land cover map are increasingly growing. But the lack of spatial information service for the general public is making it difficult for them to use spatial information and services. In this study, spatial information service strategies based on the concept of atlas, which is familiar to us through the student atlas, were proposed to promote the public users' utilization of land cover map. For this purpose, I reviewed current domestic status and overseas cases of land cover map service and proposed the future direction of spatial information service for land cover map in terms of contents, users, and system. Finally, I defined the basic concept, characteristics and functions of the Atlas Information System and recommended strategies for environmental spatial information service. The results of this study can be applied to various national spatial information as well as land cover map and contribute to the increase of general public users' utilization of national spatial data.

The accumulation of spatial information - people, building, land and businesses- is required to make a rational decision successfully by utilizing the Spatial Decision Support Systems (SDSS). Many foreign countries have utilized the SDSS by defining the minimum unit of spatial area and implementing the spatial database based on it. Even though in Korea, National Basic Districts were created for the purpose of utilizing these districts as a basic area, they have not been utilized as a basic area of managing the spatial database due to the lack of attributes data. Therefore, the goal of this research is to suggest the strategies of building Spatial Decision Support Systems through the accumulation of the spatial data based on National Basic Districts. We propose the strategies in three different fields - legal system, database and application, services. We expect that the role of National Basic Districts w ill be strengthened by executing our strategies as a minimum spatial unit of Korea.

The Korea Planning Support Systems (KOPSS) represent Korean style national policy and planning support systems using the GIS-based spatial analysis methods. The KOPSS refers to a kind of the spatial decision support systems (SDSS) or the planning support systems (PSS) for stakeholders' spatial decision-making. The KOPSS uses the existing individual databases obtained from the Architecture Information Systems (AIS) and Land Management Information Systems (LMIS) that have been constructed by information projects since the mid 1990s. The purpose of this paper is to suggest the development strategies and establish the theoretical frameworks of the KOPSS by considering the comprehensive basic composites of the GIS-based SDSS or PSS. For this, it deals with the basic concepts, the development strategies, the base environment strategies, and the promotion strategies of the KOPSS.

One of the major issues of DBMS is the buffer management. Because fetching data from the database disk is costly, the number of disk I/O's must be minimized in order to improve the DBMS performance. Although there have been many buffer management strategies to minimize the disk I/O, those strategies usually focused on just the temporal locality. Since there are the spatial locality as well as the temporal locality in the spatial database, strategies using only the temporal locality cannot achieve the optimal performance in the spatial database. In this paper, we propose a new buffer management strategy, the Spatial Locality Area Measure(SLAM) strategy, that considers not only the temporal locality but also the spatial locality. The SLAM buffer management strategy consists of two core structures, the SLM-tree and the M-LRU. We show the efficiency of the proposed strategy through experiments over various buffer sizes and reference frequencies.

One hand shopping center provides a public space for people, the other hand it is a place for commercial purpose. Although it gives an entertainment, eating and shopping places to people nowaday, owners and tenants aim to make profit from it. According to this demand designers should plan a shopping center for a comfortable place for eating, shopping and playing and they make shops and retails to increase sales by exposing those to more people at the same time. For successful shopping center architects are requested an approach with commercial strategy that shopping center raises exposure of retails and makes stay costumers longer and visit more frequently. Recently space is regarded as a mean of marketing, so-called "place marketing", because it can influence on brand image and improves the image of product. Therefore, it need to be approached with commercial consideration. Analyzing the armature this study will take a look at spatial strategies in shopping centers which especially the Jerde Partnership, one of influential firms on commercial space, designed. And it will examine how spatial strategies can be applied to commercial strategies in relation to customer information process(exposure-attention-interest-comprehension-memory) which marketers are using in advertisement for marketing and what kind of role spatial strategies can be. This study is to be basic considerations when a shopping center project will be planned.

In this paper, we propose the application models and strategies of geospatial services registries for SOA in GIS web services. Recently. a number of SOA/web services are being developed for various commercial or public applications. However, geospatial SOA services are less used than general purpose SOA services, because GeoSpatial service registries has been neglected in many GIS applications even though GeoSpatial registries are essential component for open geospatial services. These problems are due to lack of researches for GIS registry usages. In this paper, we define the role player ill GIS SOAs, and develop the various GIS web service models among the players. Besides, we suggest the applications strategies of GeoSpatial services registries in the service models.

Photochemical air quality models are essential tools in predicting future air quality and assessing air pollution control strategies. To evaluate air quality using a photochemical air quality model, emission inventories are important inputs to these models. Since most emission inventories are provided at a county-level, these emission inventories need to be geographically allocated to the computational grid cells of the model prior to running the model. The conventional method for the spatial allocation of these emissions uses "spatial surrogate indicators", such as population for mobile source emissions and county area for biogenic source emissions. In order to examine the applicability of such approximations, more detailed spatial surrogate indicators were developed using Geographic Information System(GIS) tools to improve the spatial allocation of mobile and boigenic source emissions, The proposed spatial surrogate indicators appear to be more appropriate than conventional spatial surrogate indicators in allocating mobile and biogenic source emissions. However, they did not provide a substantial improvement in predicting ground-level ozone(O3) concentrations. As for the carbon monoxide(CO) concentration predictions, certain differences between the conventional and new spatial allocation methods were found, yet a detailed model performance evaluation was prevented due to a lack of sufficient observed data. The use of the developed spatial surrogate indicators led to higher O3 and CO concentration estimates in the biogenic source emission allocation than in the mobile source emission allocation.llocation.

This study has a purpose that definitize correlationship of spatial structure and sales strategies in mixed-use complexes which established in Korea since year 2000. For this purpose, this study tries to analysis spatial structure of mixed-use facilities through space syntax theory and makes an typological categorization based on their space composition. As a result of categorization, Korean mixed-use facilities can be classed as three types. First type is integrated stacking type. Second one is parallel connecting type. Third type is room to room type. According to differences between categories, their spatial structures show different meaning with different sales strategies. Integrated stacking type sales luxury brands and expensive stuffs and it also has deep and complicated structure. That means theses spaces usually make a strategy of exclusion. Parallel connecting type sales special categories and it also has shallow and easy spatial structure. That means these facilities want to make a smooth connection between apposed volumes. Room to room type sales cheap and fancy objects and it also has simple and shallow structure. That means simple spatial structure can be lead contact customer to stuffs. These results mean spatial structure have a effect on design of sales space.

Due to characteristics of modern society including technological development, various methods engaging interaction between people and manmade environment have become one of the major issues raised in various fields of deign so called interactive design. Interactive design started as the interface between human and computer system, but now expanded to interior design field enhancing spatial experience of users. Now, many corporates are looking into interactive design to bridge the gap between company or brand identity and consumers as marketing tool. The current study investigates interactive concepts and characteristics of corporate participated public spaces and tries to define their design methods according to spatial marketing strategies. Using theoretical inquiry, cultural events and delivery of corporate identity information were defined as two major spatial strategies through cognitive or behavioral approaches. Moreover, digital, constructive, and expressive presentations were found to be most common design methods. Through this theoretical framework, 7 selected samples in Korea are analyzed in order to find detailed design characteristics. It is hoped that this study may serve in understanding current design approaches of interactive corporate public spaces and useful guideline when designing interactive public spaces not only as means of marketing strategies but even for public goods.
