  • To develop in the long view, based on context of city, the spatial program change to new spatial program that can be adopt city architectural environment. The new spatial program must have paring lot, open space, community center, which are infra structure for citizen. The needs about flexible space Increase according to complexity of spatial program. The space of absolutism, is made up hierarchy, can't accommodate complexity of spatial program. Therefore, modern architectural spaces are characterized by non-hierarchy. This research is tendency to search special quality of space program that is going complex composition according to change of modern society and modern architecture space, and analyze characteristic of inner space that have non-hierarchy to correspond hereupon.

  • Throughout the economic development era of Korea, migration occurred within a spatial hierarchy, with upward flows from rural areas to urban. The concept of step migration is a typical theory to explain these upward migration flows. Recent migration data and trends, however, indicate that migration-pattern regime shows strongly opposite-direction flows, with many of the major migration flowing downward on this national-spatial hierarchy, away from urban areas. In this study, we examine the most recent structure of migration flows up and down within the national-spatial hierarchy. We define seven tiers to tabulate origin-destination migration flows from population density of local administrative districts for the period 2001-2014, and then analyze the migration patterns between the tiers over time. The results show differentiated patterns of migration within the national-spatial hierarchy over time including specific states of migrants' life cycles.

  • This study analyzed the spatial hierarchy of Hyangkyo architecture. Hyangkyo was built on the basis of Confucianism. The results are as follows; 1) The spatial hierarchical construction responding to the site. The arrangement style of hierarchical construction changed according to the site. This is the reason that the hierarchy of Confucianism has the relationship of the upper class and the lower class, high and low of position, high of right and low of left, and the theory of division based on topography. 2) The hierarchical construction responding to the arrangement style. Buildings were hierarchically constructed according to the site of the architecture. This is the result of hierarchy. In conclusion, the spatial hierarchy means that Hyangkyo architecture had been built according to an order on the basis of Confucianism.

  • The purpose of this study is to establish the central hierarchy and urban spatial structure of Daejeon in 2040 using differentiated analysis indicators. In order to establish a central hierarchy in the future urban space of Daejeon City, three indicators were derived: population density, use of buildings (commercial, office, residential, etc.) and traffic volume data(KTDB). The results of analyzing the center hierarchy using indicators are as follows. First, the primary centers responsible for urban (core) functions are set in three areas, including Dunsan downtown, the original downtown (Daejeon Station area, designated as a special urban convergence zone), and Doan New Town, and the secondary centers corresponding to sub-city centers (regional bases). was set at 9, 10 tertiary centers corresponding to regional centers (living area centers), and a center hierarchy was established with 5 new specialized bases. Second, new secondary and tertiary centers emerged that were different from the center hierarchy in the 2030 Daejeon Urban Basic Plan. The three indicators used in this study yielded meaningful results in establishing urban spatial structure and central hierarchy that can secure urban competitiveness.

  • Spatial data warehouses provide analytical information for decision supports using SOLAP (Spatial On-Line Analytical Processing) operations. Many researches have been studied to reduce analysis cost of SOLAP operations using pre-aggregation methods. These methods use the index composed of fixed size nodes for supporting the concept hierarchy. Therefore, these methods have many unused entries in sparse data area. Also, it is impossible to support the concept hierarchy in dense data area. In this paper, we propose a dynamic pre-aggregation index method based on the spatial hierarchy. The proposed method uses the level of the index for supporting the concept hierarchy. In sparse data area, if sibling nodes have a few used entries, those entries are integrated in a node and the parent entries share the node. In dense data area, if a node has many objects, the node is connected with linked list of several nodes and data is stored in linked nodes. Therefore, the proposed method saves the space of unused entries by integrating nodes. Moreover it can support the concept hierarchy because a node is not divided by linked nodes. Experimental result shows that the proposed method saves both space and aggregation search cost with the similar building cost of other methods.

  • Most of the existing pattern mining techniques are capable of searching patterns according to the continuous change of the spatial information of an object but there is no constraint on the spatial information that must be included in the extracted pattern. Thus, the existing techniques are not applicable to the optimal path search between specific nodes or path prediction considering the nodes that a moving object is required to round during a unit time. In this paper, the precision of the path search according to the spatial hierarchy is analyzed using the Spatial-Temporal Optimal Moving Pattern(with Frequency & Weight) (STOPM(FW)) algorithm which searches for the optimal moving path by considering the most frequent pattern and other weighted factors such as time and cost. The result of analysis shows that the database retrieval time is minimized through the reduction of retrieval range applying with the spatial constraints. Also, the optimal moving pattern is efficiently obtained by considering whether the moving pattern is included in each hierarchical spatial scope of the spatial hierarchy or not.

  • Most decision support functions of spatial data warehouse rely on the OLAP operations upon a spatial cube. Meanwhile, higher performance is always guaranteed by indexing the cube, which stores huge amount of pre-aggregated information. Hierarchical Dwarf was proposed as a solution, which can be taken as an extension of the Dwarf, a compressed index for cube structures. However, it does not consider the spatial dimension and even aggregates incorrectly if there are redundant values at the lower levels. OLAP-favored Searching was proposed as a spatial hierarchy based OLAP operation, which employs the advantages of R-tree. Although it supports aggregating functions well against specified areas, it ignores the operations on the spatial dimensions. In this paper, an indexing approach, which aims at utilizing the concept hierarchy of the spatial cube for decision support, is proposed. The index consists of concept hierarchy trees of all dimensions, which are linked according to the tuples stored in the fact table. It saves storage cost by preventing identical trees from being created redundantly. Also, it reduces the OLAP operation cost by integrating the spatial and aspatial dimensions in the virtual concept hierarchy.

  • A practical use of the location information and user requirement are increased in a mobile environment which supports the portability. And Various service which GIS is related with a Spatial DB have been processed. Generally, logical relation of a traffic network which organizes the Road DB uses a basic node-link structure. In this way, Designed structure can not be flexible at various model apply and are not efficient with a database retrieval in a maintenance management side. In this research, We supplement with the problem of a existing network model and the limitation of the building through the design of a network model which uses dynamic segmentation. And we tried to implement efficient hierarchy model at the retrieval of the network and presentation. Designed model supports a stage presentation of various level and a hierarchy entity relation and We are expected to supplement a network spatial modelling function which the GIS has.

  • In this study, we surveyed historical housing settlements of Hwangjon in Bonghwa-a clan village in Youngnam district which was formed in the Chosun Dynasty. We observe the relationships among the spatial layout of clan villages, the water flows and the family hierarchies as follows; (1) when a clan village was initially formed, the water flow, which is the phylosophical foundation of Poong Soo, was the most important factor for determining the original location; (2) as villages prosper, the water flow and the family hierarchy still played an important role in determining the following geological locations; (3) in modern age, however, the water flow and the family hierarchy lost the role in detrmining the geological locations; (4) consequently, in present days, each household becomes isolated from the village. Reflecting on these observations, for village to be maintained, we conclude that we need novel practical and cohesive village forming drives that can replace the water flows and the family hierarchy in the past.

  • The basestone is a kind of foundation part of the building and can be said to deliver the loads from the upper part to ground. It is the explanation of structural role for the basestone. But the basestone has been used as the decorative element in a building. So this study is on design of the basestone. First the type division can be studied as form of the basestones. Also the investigation of development aspect of them needs to as times and the spatial characteristics. Another goal of this study is on the design characteristics of the basestone from the comparison to the basestone in ancient Japan was initiated in the architectural technology from Korea. The results are as follows. In Baekje rectangular basestones were used in static space for ceremony and circular ones were used in dynamic space for life. Also the basestones with joojwa(smoothing surface for sitting on column) were used for accessory buildings rather than main. In Silla the same type of basestone was made in a temple but according to hierarchy of buildings the sizes of them seem to have been different. The other side in Japan carved basestones were for the main buildings and for the accessory natural stones were used to. According to the hierarchy of the buildings the kinds of stones were different.
