Culture is an indispensable element in modern society in improving the quality of life for city dwellers and stimulating the urbanization. The conspicuous emergence of cultural cities, which is a new paradigm, can be understood in that context. Global cities are pursuing cultural cities, and autonomous regions in Korea are also pushing ahead with the urbanization which combines cultural elements. Specifically, Nam-gu of Incheon has set an example of successful cultural city for other autonomous regions. The cultural environmental policy of Nam-gu is deemed to have retained the infrastructure, cultural urban landscape and living space, and a plenty of contents. The real significance of cultural city lies in the pursuit of sustainable urban development as a culture-friendly city. For that, the direction of cultural environmental city has to be firmly set, and related law and system should be strengthened. Above all, it is critical to pursue human-oriented cultural city by showing citizens what roles they have to play, setting the right direction, and improving the partnership.

University has various resources such as intellectual human resource, spatial resource and facilities, and economic resource. At the same time, universities are, in general, found upon fundamental mission of public service, as well as teaching and research. Recently in Korea, it has been argued that we should make use of such resource of universities in the process of urban regeneration through university-community partnership. Yet, these arguments are lack of concreteness: 'which' kind of resource for 'what' kind of problem, and 'how'. Therefore, this research examined the case of university-community partnership in Japan and tried to find of some implications to Korean society. The reason for examining Japanese case is because Japan has experienced similar problems that Korea face such as aging population, decrease in the number of student, deteriorations of existing urban area; there are respectable amount of similarities between Japan and Korea in political, social and economic context; and because Japan has proceeded regeneration of communities through university-community partnerships.

An articulatory study (using an Electromagnetic Articulography, EMA) was conducted to explore effects of prosodic boundary strength (Intonational Phrase/IP versus Word/Wd), and focus (Focused/accented, Neutral, Unfocused/unaccented) on the kinematic realization of /m/ in the coda (${\ldots}$am#i${\ldots}$) and the onset (${\ldots}$a#mi${\ldots}$) conditions in Korean. (Here # refers to a prosodic boundary such as an IP or a Wd boundary). Several important points have emerged. First, the boundary effect on /m/s was most robustly observed in the temporal dimension in both the coda (IP-final) and the onset (IP-initial) conditions, generally in line with cross-linguistically observable boundary-related lengthening patterns. Crucially, however, in contrast with boundary-related slowing-down effects that have been observed in English, both the IP-final and IP-initial temporal expansions of Korean /m/s were not accompanied by an articulatory slowing down. They were, if anything, associated with a faster movement in the lip opening (release) phase (into the vowel). This suggests that the mechanisms underlying boundary-related temporal expansions may differ between languages. Second, observed boundary-induced strengthening effects (both spatial and temporal expansions, especially on the IP-initial /m/s) were remarkably similar to prominence (focus)-induced strengthening effects, which is again counter to phrase-initial strengthening patterns observed in English in which boundary effects are dissociated from prominent effects. This suggests that initial syllables in Korean may be a common focus for both boundary and prominence marking. These results, taken together, imply that the boundary-induced strengthening in Korean is different in nature from that in English, each being modulated by the individual language's prosodic system. Third, the coda and the onset /m/s were found to be produced in a subtly but significantly different way even in a Wd boundary condition, a potentially neutralizing (resyllabification) context. This suggests that although the coda may be phonologically 'resyllabified' into the following syllable in a phrase-medial position, its underlying syllable affiliation is kinematically distinguished from the onset.

This study attempts to expand the leverage cycle theory using the subprime real estate investors. The leverage cycle theory has demonstrated asset price fluctuations irrelevant to changes in fundamentals through the restructuring of transaction composition centered on optimistic buyers. However, it needs to understand how this theory works in the depressed housing market with low-income residential regions to explain the geographic origins of the financial crisis. In the depressed housing market, the subprime real estate investors focused on low-income residential regions. Through this spatial focus, the low-income residential regions solely have real estate investor-oriented composition of new purchase transactions in the depressed housing market. The discovery of the subprime real estate investors as new actors lays the foundation for applying the leverage cycle theory to the depressed housing market which has been a underserved area for capital investment. This attempt illustrates how the geographical reinterpretation of an economic theory reestablishes spatio-temporal context of economic phenomena.

This study consists of two parts, in which the traditional discourses about light and color are analysed hermeneutically, The first part deals with the optical and chromatic discourse that stands in the same context with the aesthetic, and the second with the analysis of color phenomenon that is constituitive of space. From the ancient time the basic parameters of the conceptual thinking such as the virtual, simulacrum, have sticked to the inevitable status, which mediates to represent the original that can never present by oneself. In modern times this specificity of the virtual could have been connected with the problem, how and by which means objects can be perceived and grasped in itself. Among the barometers to the problem ‘color’ or ‘color perception’ has been regarded as the distinct one, in which the relationship between the image and the identifying of this one, the relationship between the perceived image and the perceiving subject and the problem of the spatiality of color and surface can be dwelled on. Through the explication of the chromatic and aesthetic discourse it can be recognized that color, surface and space are interacted with one another. Colors on the surface are not only the dynamic interpoints between the memory and the forgetfulness, but also the virtual interfaces, in which the spatialising actions happen incessantly. At this point it can be illuminated that the space-constituitive dimension of color is correlative with the dimension of chromatic effects of spatialising. Therefore color as well as surface as the spatial happening must be apprehended as the one, which constitutes the spatialising and at the same time varies and shifts itself into another on the purpose of the other spatialising.

The position verification of the radiation source utilized in brachytherapy forms a critical factor in determining the therapeutic efficiency. Currently, films are used to verify the source position; however, this method is encumbered by the lengthy time interval required from film scanning to analysis, which makes real-time position verification difficult. In general, the source position accuracy is usually tested in a monthly quality assurance check. In this context, this study investigates the feasibility of the real-time position verification of the radiation source in high dose rate (HDR) brachytherapy with the use of scintillating fibers. To this end, we construct a system consisting of scintillating fibers and a silicon photomultiplier (SiPM), optimize the dosimetric software setup and radiation system characteristics to obtain maximum measurement accuracy, and determine the relative ratio of the measured signals dependent upon the position of the scintillating fiber. According to the dosimetric results based on a treatment plan, in which the dwell time is set at 30 and 60 s at two dwell positions, the number of signals is 31.5 and 83, respectively. In other words, the signal rate roughly doubles in proportion to the dwell time. The source position can also be confirmed at the same time. With further improvements in the spatial resolution and scintillating fiber array, the source position can be verified in real-time in clinical settings with the use of a scintillating fiber-based system.

In order to create an intelligent autonomous agent in virtual world, we need a sophisticated design for perception, recognition, judgement and behavior. We develop the perception and recognition functions for such an autonomous agent. Our perception mechanism identifies lines based on differences in color, the primitive visible data, and exploits those lines to grasp shapes and regions in the scene. We develop an inferencing algorithm that can infer the original shape from a damaged or partially hidden shape using its characteristics from the ontology in order to intelligently recognize the perceived shape. Several individually recognized 2D shapes and their spatial relations form 3D shapes and those 3D shapes in turn constitute a scene. Each 3D shape occupies its respective region, and an agent analyzes the associated objects and relevant scenes to recognize things and phenomena. We also develop a mechanism by which an agent uses this recognition function to accumulate and use her knowledge on the scene in the historical context. We implement these functions presented above against an example situation to demonstrate their sophistication and realism.

This study aims at examining the making and distribution course of performing arts and its converged form with technology and industry in terms of the Contents Promotion Act. Since the 2000s, the inter-area contents making and sharing methods have been changing the making and distribution structure of performing arts. The recent production of performing arts contents live videos extends the areas of arts creation and communication beyond the time and spatial boundaries of performing arts and changes the existing systems. The performing arts which started with nowness and spatio-temporal restriction on the premise is now creating a new platform over the spatio-temporal boundary through the live video. Performing arts, in convergence with the areas of technology and industries, expands universal approaches and shows the public value of cultural fairness at public performing arts centers. In this context, this study aims at seeking the possible extension of performing arts contents by examining how the so-called high-class performing arts such as opera, theatre and classical music combines with the visual industry.

The combination of multiple antennas and multi-carrier code division multiple-access (MC-CDMA) is a strong candidate for the downlink of the next generation mobile communications. The study of such systems in scenarios that model real-life trans-missions is an additional step towards an optimized achievement. We consider a realistic MIMO channel with two or four transmit antennas and up to two receive antennas, and channel state information (CSI) mismatches. Depending on the mobile terminal (MT) class, its number of antennas or complexity allowed, different data-rates are proposed with turbo-coding and asymptotic spectral efficiencies from 1 to 4.5 bit/s/Hz, using three algorithms developed within the European IST-MATRICE project. These algorithms can be classified according to the degree of CSI at base-station (BS): i) Transmit space-frequency prefiltering based on constrained zero-forcing algorithm with complete CSI at BS; ii) transmit beamforming based on spatial correlation matrix estimation from partial CSI at BS; iii) orthogonal space-time block coding based on Alamouti scheme without CSI at BS. All presented schemes require a reasonable complexity at MT, and are compatible with a single-antenna receiver. A choice between these algorithms is proposed in order to significantly improve the performance of MC-CDMA and to cover the different environments considered for the next generation cellular systems. For beyond-3G, we propose prefiltering for indoor and pedestrian microcell environments, beamforming for suburban macrocells including high-speed train, and space-time coding for urban conditions with moderate to high speeds.

Main debates in the modern geographical thoughts had been developed around the regional geography. Because regional geography had been regarded as a raison d'etre of geography, it remains solid status in geography curriculum. But unscientific nature of regional geography was the main problem of modern geography. Modern geography has developed the logical legitimation of regional geography, instead of research procedures. We examine the logic of modern geographical thoughts from 3 worldview. Here we represented the part - the whole relationship as the primary category, and classify these into three type according to the implicit proposition about the relationship. One is the organic view, which assume that the whole is greater than the sum of the parts. This view was the primary proposition held by the modem geographers. This view regarded the region as organic complex, and presume the unit region which is irreducible to the elements. The other is mechanic view, which presuppose that the whole is the sum of the parts. This view comprehend region by means of spatial order, in order to simplify the complex reality. Then we compare real condition with assumption. These two view held static assumption. Now, the third view regarded the part- the whole relationship as being dynamic. Most geographers held the organic view, although someone suggests the idea of harmony, the others suggests the idea of complex. But these view presumes the pre-industrial society in which the genre de vie was main principle of social order. Therefore It could not comprehend the regional concept in the context of the urbanization and industrialization.
