Informational urbanism is a new research area in information science. In this study, art history joins informational urbanism: Are digital artworks in public urban spaces recognized as essential assets of a smart city? We employed case study research, working with the example of the huge digital media façade of the Arthouse Graz as an artwork in a public space. In a mixed-methods approach, we asked passers-by and interviewed experts on Graz as a smart city and on the Arthouse's role concerning the image of Graz as a smart city. The research found strong hints that indeed digital artworks with large screens or media façades at public spaces are parts of a city's weak location factors as well as of the city's urban structure and may symbolize the city's smartness. A practical implication of this finding is that artists, computer and information scientists, city planners, and architects should include interactive contemporary digital art into city spaces in order to demonstrate the city's way towards knowledge society.

Koolhaas' perspective on urbanism differs from the modern urbanism and typological urbanism. The Melun-Senart masterplan, La $D{\acute{e}}fense$ masterplan shows unique characteristic different from that of conventional urbanism. The roots of this creative approach can be found in the traits of his research with O.M. Ungers back in the 1970s. Koolhaas and Ungers have collaborated intimately from 1972 to 1977 to work on urban projects. This collaboration reaches its cilmax in their project City in the City, where many of Koolhaas' core concepts such as archipelago, void/solid, plurality, infrastructure, congestion, and social condenser are introduced. This thesis will explore the development of these concepts in their collaboration and shed new light on how this period has made a transition into Koolhaas' perspective on urbanism and architecture as well as his works. The purpose of this study is to investigate these core concepts of Koolhaas in City in the City, and to find the development and the meaning of these concepts in his projects.

The purpose of this study is to construct the System Dynamics Model that can analyze urban spatial and temporal change and suggest the policy directions applicable to U-City Planning in Busan based on the SD model. It reviews previous literatures to elicit U-City issues and performs the case study to simulate urban spatial and temporal changes in Busan. The elicited results are connected into the policy directions of U-City planning. It emphasizes the necessity of business model suggestion based on U-City technology and industry not a tool, the U-City model construction that linkages and integrates the existing cities and new cities, and the excavation of U-City service model reflecting social and demographic changes.

The important of Smart City has been increasing on the driving force of 4^th industrial revolution and method to solve urban problems. Korea government introduced and implemented ubiquitous City as an intrinsic Smart City brand from the early 21^th century. Diverse types of Smart City projects were announced as national strategy by the spatial characteristics. National Test-Beds in Sejong city and Busan(EDC: Eco Delta City) are urban planning to be future city models for new town development. In the old towns in cities, various type of Smart City projects are support by government by urban growth stage; frontiers, stable or declining urban realm. 「3^rd Comprehensive Plan for Smart City(2019 ~ 2023)」 in Korea plans an important role to build innovative ecosystem and reinforce global competiveness by spreading of Smart Cities. For the successful Smart City as open and inclusive space, it is need that this space should be made by the cooperation of citizens, private sectors and local and central government.

Ubiquitous City(U-City) is spotlighted for the new paradigm to solve the problem of urbanization using ICT technology. However, due to the lower profit and the insufficient of citizen-experience service, ubiquitous service(U-Service) is perceived negatively. In this sense, a study for user-centric profitable service development is needed. This study, as a basic research for the development of U-service, is conducted to identify the factors which are affected to acceptance of the U-Service. Technology Acceptance Model is applied for the basic model of the research. The model is modified by the U-City characteristic which has user, technology, and service perspective. The proposed model is empirically tested using survey data collected from 600 citizens of 7 U-City. Structural equation modeling is employed to test the research hypotheses. The survey analysis results are able to apply for basic research of U-Service design, and provide theoretical and practical implications.

This is the urban design master plan for the Public Administration Town. The project proposes a newly configured city, where environmental and democratic principles are expressed in the shape of the urban fabric. To achieve the goal, the concepts of 'Flat City, Link City, and Zero City' were introduced. These concept show "Space fabric arrange, connection and material circulation and flow from ecological landscape". 'Flat City' shaped the government buildings into an iconic plane, and democratic society. The iconic plane's surface extends across the whole city, creating an expansive public park, which is easily accessible, and open to nature. 'Link City' connects governmental agencies to enhance their function and interactions. Government facilities, parks and green spaces, cultural facilities, commercial zones, and residential districts areas create an interconnecting network. 'Zero City' has integrated infrastructure systems to reuse waste, reduce pollution, and provide essential city functions. It creates a new wildlife habitat, making 'Zero City' a good neighborhood. This proposal was made to integrate historical, regional, nature experiences with various approaches in architecture, city, and landscape architecture.

City gas is becoming an essential resource in households due to its convenience and low price in comparison to other energy sources. However, in order to prepare for the gas market to be saturated, many city gas companies must pursue customer satisfaction management and develop happy call systems for a promising solution. In the development of the happy call systems, the difficult problem is that we cannot contact all customers because of limited resources and calling efficiency in the call center, We should find best customers according to their value. This paper suggests a methodology for the selection of happy call customers when city 9as companies consider two strategies. First, they should launch a new business area. Second, they must attempt to prevent current customers from moving from city gas to other fuels. We will discover important attributes and derive rules of weighting for the attributes through an exploration study that affect customer satisfaction and preference. Through a simulation model, we will show how many customers will be selected by our methodology.

This paper discusses Leon Battista Alberti's vision of the paradigmatic city. In his De re aedificatoria, Alberti proposes how the architecture of both individual buildings and cities should be ordered and embellished. Borrowing ideas from the ancient writers on one hand, and reflecting on actual urban reality on the other, Alberti proposes an ideal city where the sacred and the secular come together in hierarchical harmony, beautified under the principle of ornament. In Book VIII, dealing with secular public works of architecture, he writes about the composition of a new humanist city that transcends actual reality. Ornament, a central idea of his aesthetics, supports his conception of the paradigmatic city.

A new speed improvement method for quantitative superimposed EMG signal analysis to diagnose the neuromuscular dysfunction is described. The improvement is achieved through the use of efficient software and hardware signal processing techniques. The software approch is composed of the MANDF filter and HRWA algorithm which provides the optimal set and time delays of-selected templates. The hardware employs a TMS32OC25 DSP chip to execute the intensive calculation part. The purposed method is verified through a simulation with real templates which are obtained from needle EMG. As a results, the proposed method provides an overall speed improvement of 32-40 times.
