In modern society which changes from quantity-seeking society to value-seeking one, people's various lifestyles have great effect on consumption patterns and work as an important factor in choosing hotels. The fact that design hotels, which provide unique experiences with differentiated and sensitive designs by reflecting various lifestyles, recently attract attention can be understood in the same context. As a matter of fact, design hotels recently serve as destinations as they become cultural and artistic icons which reflect customer lifestyles. Especially, the designs of lobby spaces in hotels play deciding role in customers' choices while representing the nature of hotels. In this respect, under the premise that the kinds of accumulated experiences are different depending on lifestyles and preferences for specific interior spaces are influenced by association mechanism formed by experiences, this study analyzed lobby spaces of design hotels which focus on specific lifestyles from the perspective of association mechanism based on experiences. As the method of analysis, this study classified the types of lifestyles and conducted case analysis to investigate what association mechanism works to enhance the preference of design hotels by types. Study classified lifestyles into experiential activity type, social meeting type, fashion-pursuing type and hideout-preferring type and analyzed cases of lobby designs in design hotels. The results of this case analysis are as follows; First, experiential activity type mainly utilized quasi-association and approach association through senses and social meeting type utilized quasi-association and memory association through emotions while fashion-pursuing type utilized quasi-association and presumption association through intuition and hideout-preferring type utilized quasi-association and approach association through thoughts. Second, it was found that most lobby designs are characterized by association mechanism in visual formative nature and that in temporal spatial nature working in complex way, and, through such process of association expansion, space stories are created. Stories of spaces created this way become unique identities of design hotels that provide new experiences for customers.

We propose an enhanced version of the local binary pattern (LBP) operator for texture extraction in images in the context of image retrieval. The novelty of our proposal is based on the observation that the LBP exploits only the lowest kind of local information through the global histogram. However, such global Histograms reflect only the statistical distribution of the various LBP codes in the image. The block based LBP, which uses local histograms of the LBP, was one of few tentative to catch higher level textural information. We believe that important local and useful information in between the two levels is just ignored by the two schemas. The newly developed method: gradual locality integration of binary patterns (GLIBP) is a novel attempt to catch as much local information as possible, in a gradual fashion. Indeed, GLIBP aggregates the texture features present in grayscale images extracted by LBP through a complex structure. The used framework is comprised of a multitude of ellipse-shaped regions that are arranged in circular-concentric forms of increasing size. The framework of ellipses is in fact derived from a simple parameterized generator. In addition, the elliptic forms allow targeting texture directionality, which is a very useful property in texture characterization. In addition, the general framework of ellipses allows for taking into account the spatial information (specifically rotation). The effectiveness of GLIBP was investigated on the Corel-1K (Wang) dataset. It was also compared to published works including the very effective DLEP. Results show significant higher or comparable performance of GLIBP with regard to the other methods, which qualifies it as a good tool for scene images retrieval.

This study starts from the genealogical analysis of the urban public spaces through local history of Seoul which is significantly different from western countries. The analysis targets the discourse on the urban street, the basic unit of urban tissue and the settlement condition in urban life, which defines urban space-structure among the urban public spaces. And this research classifies and categorizes the value recognition and policy value occurred each period. Based on these, this research defines the progress levels of urban public design policy in Seoul as follows. Results Firstly, 1890's and 1900's was the period of development in commerce and industry, which caused congested and crowded streets. The open port policy allowed the experience of the foreign circumstance, and thus the identity of the urban streets and the value of symbolism come to realize among the society. During the Japanese colonization, urban streets put on modernized images through the urban remodeling out of the context according to the colonization policy. The brand-new values such as publicness and amenity are injected as well as modern regulations by system and authority. From Liberation to 1950's, it performed only street restoration as a repair from war with Japanese colonial system because of the political confusion and administrative vacuum. Finally, each period can be defined as follows. 1890's and 1900's can be defined as 'spontaneous finding the modernization' because urban street was intentionally transformed by the empire. Period of the Japanese colonization can be defined as 'the formation of modernized urban street concept and the compulsion of modernized regulation.' And period of from Liberation to 1950's, can be called as 'the absence of value recognition and maintenance of colonial system.' methodology.

This research proposes contextual space expression as a possibility of solution methods for local and historical issues, the matters that our contemporary architecture has to overcome. When modernistic architecture aimed for anonymous public interests denying the characteristics in historical and spacial contexts, postmodern architecture and regional architecture, etc have been striving to revive discontinued contextual meanings using various historical and environmental elements. While such attempts only borrowed architectural materials by superficially understanding the context, they could not comprehend ceaselessly changing contexts sufficiently. Choosing Jean Nouvel as one of the architects that can explain spatial plan to properly respond to such ever-changing, contemporary contexts, the researcher intended to understand his line of expressional characteristics of his architectural space and analyze his works as examples.

In Fourier magnetic resonance imaging (MRI), the number of phase encoded signals is often reduced to minimize the duration of the studies and maintain adequate signal-to-noise ratio. However, this results in the well-known truncation artifact, whose effect manifests itself as blurring and ringing in the image domain. In this paper, we propose a new regularization method in the context of a Bayesian framework to reduce truncation artifact. Since the truncation artifact appears in t도 phase direction only, the use of conventional piecewise-smoothness constraints with symmetric neighbors may result in the loss of small details and soft edge structures in the read direction. Here, we propose more elaborate forms of constraints than the conventional piecewise-smoothness constraints, which can capture actual spatial information about the MR images. Our experimental results indicate that the proposed method not only reduces the truncation artifact, but also improves tissue regularity and boundary definition without oversmoothing soft edge regions.

Parametric design systems serve as powerful assistive tools in the design process by providing a flexible approach for the generation of a vast number of design alternatives. However, contemporary parametric design systems focus primarily on low-level engineering and structural forms, without an explicit means to also take into account high-level, cognitively motivated people-centred design goals. We present a precedent-based parametric design method that integrates people-centred design "precedents" rooted in empirical evidence directly within state of the art parametric design systems. As a use-case, we illustrate the general method in the context of an empirical study focusing on the multi-modal analysis of wayfinding behaviour in two large-scale healthcare environments. With this use-case, we demonstrate the manner in which: (1). a range of empirically established design precedents -e.g., pertaining to visibility and navigation- may be articulated as design constraints to be embedded directly within state of the art parametric design tools (e.g., Grasshopper); and (2). embedded design precedents lead to the (parametric) generation of a number of morphologies that satisfy people-centred design criteria (in this case, pertaining to wayfinding). Our research presents an exemplar for the integration of cognitively motivated design goals with parametric design-space exploration methods. We posit that this opens-up a range of technological challenges for the engineering and development of next-generation computer aided architecture design systems.

A deserted town once vibrant with active commercial activities around a railroad station now tries to find a way to escape from depression and revive its life with a renewed civic pride. An open space adjacent to the Main Street, the commercial district of Buzzards Bay, Massachusetts, is waiting to be transformed and reconfigured to be a new ecological park to boost the economy of the community. Bridge Park is 26-acre land abutting the Cape Cod Canal with a railroad bridge as a backdrop. The existing condition of the site with a small salt marsh, woodland, lawn, and the vestige of old railroad easement along with the proximity to the commercial district poses an interesting question of how to make a medium scaled ecological park within an urban context. This paper examines the winning design proposals for the Bridge Park submitted to the International Design Competition held in April, 2005. Six winning proposals were introduced and discussed in terms of categories related to the trend of contemporary landscape design such as; 1) ecological ordinariness and geometric figures, 2) topography and spatial imagination, 3) minimal programs and open put 4) time and process oriented design, 5) park and economic effects and 6) diagrammatic plan and photo montage. Bridge Park Design Competition confirms the complex characteristics representing the contemporary landscape design overcoming the dichotomy between nature and culture and the 'pastoral ecological design' and 'landscape as an art'. The Park becomes the activating agent for the community rejecting the conventional and passive role as a romantic picturesque landscape. Bridge Park International Design Competition is a meaningful event to test the idea of new ecological urban park, and to fine-tune the trend of the contemporary urban park design.

This study includes determination of liquefaction potential in Erzincan city center. Erzincan Province is situated within first-degree earthquake zone on earthquake map of Turkey. In this context, the earthquake scenarios were produced using the empirical expressions. Liquefaction potential for different earthquake magnitudes (6.0, 6.5, 7.0) were determined. Liquefaction potential was investigated using Standard Penetration Test (SPT). Liquefaction potential analyses are determined in two steps: geotechnical investigations and calculations. In the first steps, boreholes were drilled to obtain disturbed and undisturbed soil samples and SPT values were obtained. Laboratory tests were made to identify geotechnical properties of soil samples. In the second step, liquefaction potential analyses were examined using two methods, namely Seed and Idriss (1971), Iwasaki et al. (1981). The liquefaction potential broadly classified into three categories, namely non-liquefiable, marginally liquefiable and liquefiable regions. Additionally, the liquefaction potential index classified into four categories, namely non-liquefiable, low, high and very high liquefiable regions. In order to liquefaction analysis complete within a short time, MATLAB program were prepared. Following the analyses, liquefaction potential index is investigated by Iwasaki et al. (1982) methods. At the final stage of this study, liquefaction potential maps and liquefaction potential index maps of the all study area by using IDW (inverse distance weighted) interpolation method in Geostatistical Analyst Module of ArcGIS 10.0 Software were prepared for different earthquake magnitudes and different depths. The results of soil liquefaction potential were evaluated in ArcGIS to map the distributions of drillings with liquefaction potential. The maps showed that there is a spatial variability in the results obtained which made it difficult to clearly separate between regional areas of high or low potential to liquefy. However, this study indicates that the presence of ground water and sandy-silty soils increases the liquefaction potential with the seismic features of the region.

This study is primarily to investigate the alienation process that constitutes the regional identity of the border region in Kyunggi Province. It both discusses the concept of social exclusion and its application for a theoretical framework and examines patterns and formation of the alienation process based on the field survey. The empirical results show that the alienation process which defines the border region as a geography of place poverty and exclusion has been deepened through economic, social, cultural and spatial processes. In terms of material well-being and social participation, especially, the alienation is shown to form in every aspect of people's lives in the border region. The alienation gives rise to the cultural stigmatization which first builds up negative images of the region and then aggravates region's development potential as well as its future prospect. In addition, the alienation in the context of the border region turns out to be unique compared to major characteristics of other backward regions as well as quite spatially differentiated across the border region in Kyunggi Province.
