The residential space of humans has continuously developed to the most suitable form considering the natural and social environment. Based on this, it has become a unique residential architectural culture of an area. In the architectural field, the space of residential structures is being categorized topological aspect and the quantitative indicators are being calculated to conduct an objective comparative analysis of the characteristics of space by regional groups and individual rooms. Hence, the purpose of this study is to investigate the characteristics of the spatial composition of Hanok which a modern residential structure connecting traditional residential architecture with modern residential architecture. Hanok generally had a similar spatial composition to that of the traditional Hanok. However, a minor change was spotted due to it being a modern Hanok. It was objectively determined through the environmental characteristics that this form of spatial composition is due to the influence of the Japanese colonial era as the Western lifestyle of inner space centered lifestyle was introduced in the same period that the Jeonju Hanok was mostly created. The sequence of topological spatial gene of Hanok in Jeonju Hanok Village appeared in the order of Toetmaru - Madang - Anbang - Geonneonbang - Meorit bang - Kitchen.

In Europe, traditionally the low-rised buildings for public art museum have been constructed since the 18th century like any other buildings and these are because of the technical issue for construction difficulty. Even if the low-rised art museum buildings are still continued for it's construction, gradually the high-rised art museum buildings begin to be build due to the development of contemporary technology in high-dense modern urban space. This tendency of high-rised art museum building in recent years is expected to affect on the interior space of it and most of all the spatial change in conjunction with circulation system variation is remarkable. Because the circulation system in art museum means tourist's spatial experience and it normally controls the experience of knowledge in art museum. This study is to understand how the multi-floored art museums in Europe affect to the spatial structure and how this is related to the circulation system. And also the study raised an issue on what it's social meaning is. Through these analysis the study can provide the meaning of multi-floored art museum and basic indication in art museum planning. To understand this, the study calculated the number of stories, number of vertical circulation and number of ring-structure space. Also the study tired to use space syntax tools, which are connectivity, integration value, integration value in major space, integration value in vertical circulation and intelligibility value. those tools alculated topological transfiguration of the whole space.Throughout the study, it was concluded that the influence of high-rised art museum in Europe changed the spatial structure and circulation system. The topological center of art museum that has been the grand space since 18th century changed to the vertical circulation due to the it's roll of distributing visitors to each floor. It became a starting point of spatial deployment and experience in art museum.

지금까지 명확하게 정의된 경계를 갖는 공간 및 시공간 객체 모델 개발에 관한 많은 연구가 수행되어 왔다. 그러나, 이들 모델은 지리 분석과 이미지 해석에 관한 많은 응용에서 식별되는 불확실한 경계를 갖는 공간 및 시공간 객체에 직접적으로 적용될 수 없다. 따라서, 이 논문에서는 불확실한 공간 및 시공간 객체에 적용할 수 있는 불확실한 시공간 데이터 모델을 제안하고, 이 모델을 기반으로 불확실한 시공간 객체간의 위상 관계에 관한 연산자를 정의하고, 연산 알고리즘을 설계하였다. 제안된 모델은 기존 모델과의 호환성을 위해 개방형 GIS 명세서를 기반으로 하는 시공간 데이터 모델을 확장하여 설계하였다. 불확실한 시공간 객체는 시간에 따라 위치와 모양이 불연속적으로 변하는 객체와 시간에 따라 위치와 모양이 연속적으로 변하는 객체로 정의하였으며, 확장된 9-IM을 사용하여 이들 객체간의 위상 관계를 정의하였다. 제안된 모델은 천연자원 관리시스템, 날씨 정보 관리 시스템, 지리 정보 관리 정보 시스템 등에 효율적으로 적용될 수 있을 것으로 기대된다.

This paper deals with a new methodology for topology optimization in which the topology of the design domain may change during the shape optimization process. To achieve this, the concept of the topological gradient is introduced to compute the sensitivity of an objective function when a small hole is drilled in the domain. Based on shape and topological sensitivity values, the shape and topology of the design domain may be simultaneously changed during design iterations if necessary. To verify the advantages and also to facilitate understanding of the method itself, two electrostatic design problems have been tested by using 2D finite element analysis: the first is the inverse problem of a simple dielectric model and the second is the rotor design of a MEMS actuator.

Studies of Internet algorithms or policies require experiments on the real large-scalenetworks. But practical problems with large real networks make them difficult Instead many researchers use simulations on the Internet topology models. Some tried to find out abstract topological properties of Internet. And several models are proposed to reflect Internet's topological characteristics better. But few studies have been performed on how to model the evolution of Internet. We propose algorithms for modeling addition and removal of nodes and accompanied change of topologies. We analyze the topologies generated by our algorithms to observe that they obey power-laws better than those generated by existing ones. These algorithms are also expected to be helpful in predicting future topologies of Internet.

A topological theory has been introduced to explain and evaluate the fractional volumes of system materials, the change of the weight and concentration of monomer molecules, molecular weight distribution, and interaction functions of polymer-polymer and polymer-oligomer, etc. for dispersion polymerization. The previous theory of Lu et al. has offered only an incomplete simulation model for dispersion polymer systems, whereas our present one gives a general theoretical model applicable to all the polymerization systems. The theory of Lu et al. considered only the physical property term caused by interaction between matters of low molecular weight (i.e., diluent, monomer, and oligomer) and polymer particles without dealing with physical properties caused by the structure of polymer networks in polymer particles, while our theory deals with all physical effect possible, caused by the displacement of not only entangled points but also junction points in polymer particles. The theoretically predictive values show good agreement with the experimental data for dispersion polymerization systems.

This study was done to detect the topographic and terrain change of the vicinity of the west coast. To make the basic map of the change in topology and terrain, the mosaic images were made using the images from the satellite, which were given the geometric correction based on the GCP (Ground Control Point) and DEM (Digital Elenation Model) data. The accuracy of the images was examined by .empaling them with CCP through 1:25,000's digital map. After that, among the resultant images of the 1970s and 2000s, those of Sihwa, Hwaong and Ansan, the lands reclaimed by drainage were compared to observe the change in the area. From this study, the accuracy of the images of the west coast from satellite could be acquired and the change of the topology and terrain was detected effectively. From the results, it was known that, in case of the land the topological change was not so big due to the development in the reclaimed land or the bare land. In Sihwa, the size of the land was increased 180 $\textrm{km}^2$ and that of the seashore was decreased 110 km. in Hwaong the size was increased 50 $\textrm{km}^2$ and in Ansan the city space was increased 71 $\textrm{km}^2$ due to the formation of the industrial complex.

The purpose of this study is to develope a CAD-based tool for rasterization of polygonal vector map in AutoCAD. To identity the layer property of polygonal entity with user-defined coordinates as topology, algorithm in processing entity data of selection set that intersected with scan line was used, and the layers were extracted sequentially by sorted intersecting points in data-list. In addition to the functions for querying and modifying topology, two options for mapping were set up to construct plan projection type and to change meshes' properties in existing DTM data. In case of plan projection type, user-defined cell size of 3DFACE mesh is available for more detailed edge, and topological draping on landform can be executed in case of referring DTM data as an AutoCAD's drawing. The concept of algorithm was simple and clear, but some unexpectable errors were found in detecting intersected coordinates that were AutoCAD's error, not the utility's. Also, the routines to check these errors were included in algorithmic processing. Developed utility named MESHMAP was written in entity data control functions of AutoLISP language and dialog control language(DCL) for the purpose of user-oriented interactive usage. MESHMAP was proved to be more effective in data handling and time comparing with GRIDMAP module in LANDCADD which has similar function.
