This paper addresses the problem of locating a telephone switching center at new establishing city or town. There have been several studies on the location of telephone switching center at an existing telephone network to cope with the expanding subsciber's demand, in most of which only the economic factors were considered and was determined where the switching center is established in order to minimize the total cost. This paper, However, deals with the social factors as well as the economic ones. We develop a location model considered these two factors simultaneously by using a fuzzy approach. Finally, we apply the model to locate a new telephone switching center at the Haeundae where the Pusan City intends to construct a new town.

Globalized cities are currently showing changes due to autonomous driving (AD). It is also maximizing globalization connections in cities where autonomous mobility is as complex as AD. The purpose of this study is to reveal that cities that realize AD and mobility will grow into globalized cities. Several cities, including New York and Shanghai, have attempted and are in progress, but failed cities are increasing. Although the technology of AD and the trust of citizens are prioritized, the city that has built the city's infrastructure is expected to be a city that has succeeded in AD. This is because commercialized cities or AVs will become hubs for mobility globalization, excluding rapid climate change or AV companies, and empirical analysis has been conducted that if AVs fail in metropolitan New York due to urban complexity (population density), urban economy size (GRDP), patents, number of consumers, infrastructure public EV chargers, and road quality. It examines whether the realization of AD by region and country affects overall national innovation. As a result, even if AV succeeds in large cities such as New York, Seoul, which has a higher population density (complexity), has a negative meaning, and a more similar Tokyo has a positive meaning. It can be seen that regional research on AV should also be prioritized in large cities such as Shanghai. This means that in order for AV to be realized in each city, the construction of AI infrastructure data must be actively changed to establish globalization of cities for economic growth as autonomous mobility.

The purpose of this study is to analyze the characteristic of common space of public schools in New York City and how the common space can perform a decisive role in enriching public space not as simply connecting between programs but as common space for a wide range of uses for communities as well as students. This study illustrates with a general design guideline of SCA(School of Construction Authority) and how the rules help the common space as an interactive link between community and site/site and school building/building and outdoor space/outdoor space and lobby in the urban context. Since its founding in New York City, 1958, Mitchell/Giurgola Architects office has dedicated itself to working with institutions and public and private schools for 50 years and has been working with SCA for 10 public schools since 1990. Through five school examples by Mitchell Giurgola architects, the study describes how the office suggests public "place" interweaving inner public space and outer public space through lobbies. A result of this research can be proposed what improvements should be made on common space in domestic schools by analyzing of positive aspects of SCA schools.

How parks are to be made in the twenty-first century should certainly be different. This is the inevitable conclusion of the recent significant international design competition for Downsview Park in Toronto, 2000. The purpose of this critical study is to investigate new strategies for urban park design manifested in the proposals of that competition and to explore alternative ways of landscape design that could solve the recent crisis of urban parks. Tree City, the winning entry, and other final entries proclaim that city is park and park is city. In this sense, Downsview Park marks the end of traditional Olmstedian parks and the dichotomy between city(culture) and park(nature). Rem Koolhaas and Bruce Mau's Tree City will become the model for urban park design in the near future. There are three reasons for this. First, its design is a strategy rather than a form. We can interpret that Tree City is to be developed over time as directed by six strategies: grow the park, manufacture nature, 1000 pathways, sacrifice and save, curate culture, destination and dispersal. Second, it places faith in landscape as a revenue generator instead of a fiscal liability. Third, its implementation is possible with crude installation, requiring virtually no craft. Koolhaas and Mau intend for Downsview to be an environment that is never actually designed but is formed through natural succession, cultural action, and programmatical insertions. Rather than designed objects and formal solutions, their strategy is to allow the landscape to evolve with changing uses.

Because of the need for new antimicrobial substances with novel mechanisms of action, we report here the use of an Acinetobacter reporter system for high-throughput screening of active antimicrobial agents. The bioreporter Acinetobacter strain DF4/PUTK2 carrying luciferase genes luxCDABE was chosen because of its ecological importance and it is widespread in nature. This bioreporter is genetically engineered to emit light constitutively that can be measured in real time by luminometry. Hence, this reporter system was employed to determine the bacteriostatic actions of spent-culture supernatants derived from twelve bacterial isolates. Out of the results, the strongest bioluminescence inhibitory effect of the supernatants was recorded with Bacillus cereus strain BAC (S5). Subsequently, ethyl acetate extracts of extracellular products of strain BAC (S5) were separated by a thin-layer chromatography (TLC). Based on the bioluminescence inhibitory assay, three fractions were found to have antimicrobial activity. One fraction (C) having the strongest antimicrobial activity was further purified using TLC and characterized by IR, $^1H$ NMR, mass spectrometry, SDS-PAGE, and amino acid composition analysis. The results predicted the presence of 2-pyrrolidone-S-carboxylic acid (PCA) and the octadeconic-acid-like fatty acid. Fraction C also demonstrated a broad inhibitory activity on several Gram-negative and Gram-positive bacteria. In conclusion, the Acinetobacter reporter system shows great potential to be a reliable, sensitive, and real-time indicator of the bacteriostatic actions of the antimicrobial agents.

Hamburg is going with the HafenCity Project to create new urban space for city's bustling central district. HafenCity will add an additional 155 hectares to Hamburg's central urban area, increasing its total area by some 40 percent. The new developments in HafenCity will be oriented towards the River Elbe and the great seaport. Its centre will have a close relation to water. They will be used for the construction of a fascinating mix of residential accommodation, offices, cultural and leisure amenities, retail facilities and restaurants set in a framework of an elaborate urban layout. This study is focusing on the purpose of the project goals, the task of the Hamburg authorities and GHS (Gesells chaft f$\ddot{u}$r Hafen und Standortentwicklung) and an urban planning ideas competition (draft masterplan). Regarding of the new trend of the reurbanisation in Europe, the aim of this study will be to find out, in which way Hafencity is trying to develope the new city district as a model for the European inner city of the 21st century.

In recent years, Ubiquitous City (u-City), the integrated and convergence of ubiquitous services, infrastructure, technologies and city management of the new future development city, is being initiated by the Korean government and local authorities as their new national growth engine. However, a performance measurement system for evaluating and monitoring the impacts of U-City implementation is yet to be established. This paper aims to develop an integrated performance management system (PMS) and extensively used as a tool for managing performance activities to support the visions and goals of the u-City operations. Based on current reviews on the literature and interviews with experts drew Critical Success Factors (CSF) and Key Performance Indicators (KPI) by four different measurement domains including U-City services, infrastructure, technologies, management and developed into an integrated performance measurement system based on the Balanced Scored Card (BSC) perspective. The system also provides number of examples of 'u-City Strategy Map' which illustrates a causal relationship between CSFs to execute u-City visions and goals.

Agricultural Technology Center is an education center to provide agriculturalists with information and technology related with agriculture. As domestic and international environment of agriculture and rural area is changing, functions and roles of Agricultural Technology Center are evolving according to stream of times. In 1995, a new urban and rural complex city was created for symbiotic relationship between city and rural area, As a result, user group of Agricultural Technology Center expanded to nonagriculturalists. Though the change of agricultural extension service is necessary to perform extended functions of rural area and to satisfy needs of new group of users, it is difficult to find enough studies on new functions and roles of Agricultural Technology Center to manage the service change. Therefore, this study is aimed to suggest new functions and roles of Agricultural Technology Center according to stream of times. This study were surveyed through questionnaire targeting users of Namyangju Agricultural Technology Center to compare user group awareness of Agricultural Technology Center in urban and rural complex city. According to this study result, while main purpose of agriculturalists' visiting at Agricultural Technology Center was participating in education programs related with agriculture. In contrast, nonagriculturalists usually visited the center for agricultural understanding, leisure activities, and children education, participating in field work programs. From the survey result of required functions of the center, it was revealed that nonagriculturalists expected urban agriculture, research for living improvement in rural area, adjustment education for returning farmer, and function of farming promotion, comparing agriculturalists. It is verified that this difference of user group awareness reflects the necessity that Agricultural Technology Center should change services and accept increasing use of nonagriculturalists with new functions and roles.
