다양한 도시의 형태를 입체적으로 조망해 볼 수 있도록 하기 위하여 입체 지형조감도를 작성하였고, 이를 시공간에서 동영상으로 보여주기 위하여 3차원 시뮬레이션을 실시할 수 있도록 하였다. 입체 조감도의 제작은 투시기법을 이용한 이미지 제작 기법을 이용하였으며, 그 기본 재료가 되는 영상들은 다음과 같이 준비하도록 하였다. 준비영상으로는 우리나라 아리랑 위성의 EOC(Electro optical Camera) 영상을 이용하였으며, 국토지리정보원에서 국가기본도로 제작한 1/5,000수치지도의 등고선으로부터 추출하여 임의로 오차가 보정된 DEM(Digital Elevation Model) 생성과 1/1,000 수치지도의 도로 레이어 벡터파일로 제작된 도로선을 분류하여 대상지의 3차원 영상 위에 중첩시켜 처리하는 것으로 하였다. 특히 이번 연구에 사용한 도심지역의 도로망 구성 데이터는 새주소 부여를 위해 제작된 1/1,000축척의 간선도로를 최대한 이용함으로서 새주소에서 사용하게 될 주소체계와의 연계성을 크게 염두에 두어 제작하도록 연구하였다.

Baroque period was fundamentally different from the previous ages in terms of various aspects. Not only the social, economical, and cultural changes, but also ways of experiencing architectural space were essentially changed. Space in Baroque architecture was no more confined in the strict medieval order and proportions, but it became more flexible and dynamic by applying many interesting spatial concepts as well as design methods. That is why Baroque architecture somehow has been re-considered in the present time. Various contemporary architects and theorists attempt to apply ideas in the Baroque architecture to enhance and rich spatial experience. This thesis aims to study the methods of constructing spatial depth in some of Baroque architecture. First of all, theoretical research on the Baroque art in terms of depth expressions compared to the previous ages based on Heinrich $W{\ddot{o}}lfflin$ was mentioned. After explaining the general concepts and methods of spatial depth in Baroque architecture, two case buildings were selected to be further analyzed. They are San Carlo alle Quattro Fontane and Cappella di Santissima Sindone. They have unique ways of expressing the spatial depth in which people experience particular spatial feelings. Based on the case analysis, this study was concluded that the ideas as well as design methods for spatial depth can be applied in contemporary architectural designs in various ways.

While many criminal studies have focused on the motivation of offenders and avoidance of victimization in the micro perspective, there have been a number of theoretical developments emphasizing space as a direct factor that influences the incidence of crime. The main purpose of this study is to analyze the effects of regional characteristics and violent crime incidence in Korea. Applying diverse spatial econometrics models that have less been utilized in the crime literature, this study finds an important association between spatial accessibility and crime incidence. The results suggest that the type of predominant business and the level of road accessibility affect the vulnerability of areas with respect to the incidence of violent crime. This study concludes with some important implications for urban planners and policymakers with respect to crime control and prevention.

본 논문은 공간객체의 영향력을 고려한 클러스터링을 위한 알고리즘인 DBSCAN-SI를 제안한다. DBSCAN-SI는 기존의 DBSCAN과 DBSCAN-W를 확장한 것으로 공간클러스터링 시 비공간 속성들을 영향력으로 변환한다. DBSCAN-SI는 클러스터링에 사용되는 속성에 의한 영향력이 클수록 클러스터에 포함될 확률을 높여주어, 단지 공간적인 거리뿐만이 아니라 영향력의 크기를 반영하여 군집화를 수행하기 위한 알고리즘이다. 이 논문에서 제안한 클러스터링 기법은 주변에 있는 객체들이 특정 속성 중심으로 보았을 때, 영향력이 큰 객체임에도 불구하고 주변에 객체가 드물게 있으므로 인하여 클러스터에서 배제되게 되는 기존 알고리즘의 단점을 보완해 줄 수 있다.

This study is purposed to find the transition of the perspective connected with visual modality. The perspective based on Greek optics and euclidean geometry and rediscovered in Renaissance represents the object according to the particular moment and the point of view, is a principal fact which affect architecture, the form of a city and the spatial organization and symbolizes an ideal of the times. It embodied perception which treats the space rationally on the basis of realism and became visual modality based on the separation of the seeing subject and the world of the object. The point of view became one with the vanishing point which made up the shape and after Renaissance for four hundred years a straight line, a right angle and a circle got to be favorite geometrical choices in architecture. A fixed point of view of the subject is getting to change and break up fundamentally by the new visual technologies of the modem times.

본 연구의 목적은 GIS기술을 이용하여 적조의 시공간적인 분포를 분석하는 것이다. 적조에 의해 발생하는 피해는 적조 생물종에 따라 다양하게 나타난다 때문에 적조의 피해를 저감하기 위해서는 시-공간적인 적조 생물종의 분포특성을 파악하는 것이 중요하다. 이러한 관점에서 우리는 최초의 적조발생지역, 공간적 발생빈도, 적조의 이동 등을 분석하였다. 본 연구에서 사용된 공간자료는 적조 속보 보고에 의해 공간분포를 디지타이징하였고, 적조데이터베이스를 구축하기 위해 적조 생물종, 생물 밀도, 수온 등의 다양한 속성자료를 구성하였다. 적조의 시-공간적 분포 특성을 분석하기 위해 다양한 공간분석기법을 적용하였다. 이러한 공간분석 결과로부터 남해에서의 시-공간 적이 적조 공간 정보를 얻을 수 있었다.

This study was firstly to reflect upon the background of the generation and the urban spatial value and significance of the medieval plaza. The main aim of this study was to extract the spatial determinants which give the great influence on the formation of the medieval plaza and in addition the endogenous rules and aesthetical grounds regarding the respective elements. Especially they could be applied to the design guideline. They are dimension(volume and scale), shape, elevation as the morphological elements and enclosure, proportion, grade difference, spatial sequence and plaza group as the spatial determinants and visual sequence, visual or spatial boundary, approaching axis and perspective effect as the aesthetic and visual elements and function(use), human behaviour as the social-behavioral elements and otherwise, for instance, plaza furniture, ground decoration and vegetation. This study was intended to analyze each elements based on the classical historical literatures and to suggest the planning conditions for composing the ideal plaza referring to the cases and literature review on the medieval plaza and finally is expected to contribute to the plaza design methodology.

A phase delay spectrum model towards the representation of spatial coherence of stochastic wind fields is proposed. Different from the classical coherence functions used in the spectral representation methods, the model is derived from the comprehensive description of coherence of fluctuating wind speeds and from the thorough analysis of physical accounts of random factors affecting phase delay, building up a consistent mapping between the simulated fluctuating wind speeds and the basic random variables. It thus includes complete probabilistic information of spatial stochastic wind fields. This treatment prompts a ready and succinct scheme for the simulation of fluctuating wind speeds, and provides a new perspective to the accurate assessment of dynamic reliability of wind-induced structures. Numerical investigations and comparative studies indicate that the developed model is of rationality and of applicability which matches well with the measured data at spatial points of wind fields, whereby the phase spectra at defined datum mark and objective point are feasibly obtained using the numerical scheme associated with the starting-time of phase evolution. In conjunction with the stochastic Fourier amplitude spectrum that we developed previously, the time history of fluctuating wind speeds at any spatial points of wind fields can be readily simulated.

수학교육에서 도형영역 학습은 공감감각 기르기와 도형과 관련된 개념형성을 주요 특징으로 한다. 공간감각 기르기 활동은 주로 여러 가지 변환의 관점에서 다루고 있으며 도형학습과 관련된 수업모형은 주로 개념형성 모형을 따르고 있다. 그러나 개념과 개념을 이어주는 연결성과 관련된 학습 내용은 부족하다. 본 연구에서는 공간감각을 도형에 관한 직관과 도형과 관련된 개념들 사이의 관계적 이해의 능력으로 보고 등주문제 분석을 통해서 공간감각 기르기 활동과 관련된 교수 학습 자료를 추출하고 이를 바탕으로 한 사례분석을 통해 교육학적 시사점을 얻고자 한다.

This study provided a new research perspective for processing and analyzing AE data to evaluate rock failure. Cluster method and information entropy theory were introduced to investigate temporal and spatial correlation of acoustic emission (AE) events during the rock failure process. Laboratory experiments of granite subjected to compression were carried out, accompanied by real-time acoustic emission monitoring. The cumulative length and dip angle curves of single links were fitted by different distribution models and distribution functions of link length and directionality were determined. Spatial scale and directionality of AE event distribution, which are characterized by two parameters, i.e., spatial correlation length and spatial correlation directionality, were studied with the normalized applied stress. The entropies of link length and link directionality were also discussed. The results show that the distribution of accumulative link length and directionality obeys Weibull distribution. Spatial correlation length shows an upward trend preceding rock failure, while there are no remarkable upward or downward trends in spatial correlation directionality. There are obvious downward trends in entropies of link length and directionality. This research could enrich mathematical methods for processing AE data and facilitate the early-warning of rock failure-related geological disasters.
