This study analyzed the influencing factors for urban redevelopment projects with a relatively long project duration in the context of Seoul's increasing urbanization rate and aging. Among the business areas that have been designated since 2005 and have been approved for the management and disposal plan of the entire Seoul area, 75 business areas have been set as targets. A hedonic price model was used to analyze the project area, economic, and locational characteristics as independent variables with the project duration from designation of zones to approval of management and disposal plans as dependent variables. As a result of the analysis, the smaller the project area, the larger the area occupied per union member, the larger the land price change rate, and the smaller the KOSPI index, the shorter the required period. This study has the distinction of empirically analyzing the effect of characteristic variables considering size and economic and locational characteristics on period. It provides implications that the area of the business area, the number of union members, and economic conditions should be considered when establishing a business area.

The deep mixing method, which is generally considered as a method for improving soft ground, is assessed in terms of its applicability for urban construction. Using small equipment tailored to perform deep mixing in congested urban areas, deep mixing was performed to reinforce the foundation ground of a retaining wall in a redevelopment site in Seoul. Strengths characteristics, construction vibrations and displacements induced to an adjacent old masonry wall were evaluated by laboratory tests and field monitoring. The results indicate that the strength of ground was improved appropriately whilst the vibrations and displacements induced by deep mixing were slight enough to satisfy the general requirements for construction works in urban environments. Therefore, it is concluded that deep mixing method can be a practical option for foundation methods in urban construction works where minimizing noise and vibrations is an important concern.

The Changing Characteristics of Office Location in Central Seoul In recent years, central Seoul has been experiencing a dynamic transformation. In the process of reorganization of urban industrial structure including tertiarization and quaternarization of the economic base of Seoul, business services are growing very rapidly and large scale urban renewal projects are agilely implemented. Downtown office activities become a nucleus for economic performance of Seoul and high-rise office buildings steer the landscape transformation of central Seoul. Even though there appear to exist some evidences that office districts have dispersed to several subcenters, major office activities are still concentrated in the central Seoul. This paper redefines office industry in a narrow meaning comprising only relevant economic sectors and office buildings as office activity-functioning units. It then explores the industrial networking and territorial specialization of office activities focusing on the dual process of concentration and dispersion in Seoul. The changing characteristics of the downtown linkages of office activities in this post-industrial era transforms the spatial economy of central Seoul into more flexible and volatile, while territorial concentration of power and control functions are fortified at the same time. Finally, the paper addresses the development of manufacturing-tertiary-quaternary industrial complex, which can be regarded as new industrial clusters, selling cultural economy of urban space and possessing placeness or images for clients and customers, in relation to urban competitiveness and territorial specialization of large metropolitan areas.

Recently, urban retrofit and extension, development of new buildings and facilities, and construction of underground structures like subway tunnels in urban areas give rise to significance of site investigation at urban areas. However, ambient electric noises, traffic vibrations, embedded objects work as obstacles to high-quality and accuracy in site investigation at urban areas. In this paper, a new technique called the pseudo-DC resistivity survey (in brief, PDC-R) was proposed to minimize the adverse effect of ambient electrical noises in resistivity survey. PDC-R technique utilizes an AC current with frequency range of 0.1 to 1.0 Hz rather than DC current, which is used for conventional resistivity survey. The motivation of using low-frequency AC current is to avoid 60-Hz components or its multiples in the resistivity survey which ambient noises are mostly composed of. The implementation of PDC-R technique also included the parametric study on skin effect, frequency effect and current-level effect, which led to the determination of optimal values of frequency and current level for PDC-R survey. The reliability and feasibility of PDC-R technique was verified through field tests, accompanied by the comparison with DC resistivity survey and CapSASW tests.

Many cities in Japan retain older city structures with buildings in traditional form and style. Visitors are fascinated by charms and tranquility of pre-modern life styles. Architectural features of olden days are well conserved or carefully restored on purpose. In the case of Kawagoe city near Tokyo, local residents are largely replete with visitors without being necessarily aware of slow commodification of historic spaces. Kawagoe is yet socio-culturally sustainable and financially fit. This paper intends to analyse conservation strategies, with focus on architectural heritage, taken for the historic city of Kawagoe. With the population of 300,000 in the suburb of Tokyo, it is one of the best known historic cities in Japan. Kawagoe grew as a merchant city since 1700s, and it once reached to a major port of silk trade en-route to Edo (Tokyo) from northen provinces. Tourism industry is discovered as a key element in the conservation strategies applied to revitalize historic city center, Ichibangai, an important cultural heritage site with special reference to kurazukuri. This paper argues that augmentation of conceptions in architectural heritage is not only advantageous for the conservation of historic urban environment but it also provides opportunities for sustainable urban renewal.

This study analyzed the urban structure of Jinju city where urban doughnut phenomena, development of new town at suburban zone and establishment of innovation city appear. The sphere of this study was set limit to Jinju's dong area due to taking the limitation of data. Multivariate analysis was done by using 24 variables to classify into seven clusters(CBD, Industrial Area, Residential Area etc). We studied regional condition and problems at the relation between analyzed regional features of this study and development principles at the upper planning. Jinju city needs urban redevelopment, reconstruction works and redevelopment promotion project for urban outworn zone in view of the regional conditions to innovate outdated city image and restore western Gyeongnam as a central city and also they should promote innovative city that is progressing now and construction of new town that is linked with Sangpyeong industrial complex removal as well as the whole Chojang-dong zone. In conclusion, this study will help to understand regional phenomenon like regional development project and urban management.

Recently, a research of the urban regeneration has been performed very actively. This is one of the efforts to resolve various social and economic problems coming from the existing deteriorated building and facilities by new urban development or redevelopment. However, an urban regeneration has a characteristic to be unable to ensure the project performance due to the exposed numerous risks coming from the various and complex stake-holders, and its mega sizes. This paper proposes the method of risk performance index in order to improve an efficiency of performance measurement expanding to the risk view point from the existing integrated cost/schedule performance measurement. A risk performance index is compatible with the existing EVMS, and can make the performance measurement in 3 dimensions of the integrated cost/schedule/risk with 18 sub-indexes and variables.

북항 재개발사업에 대한 기대와 관심은 항만시설의 기능성과 효용의 차원과 나란히 지역민의 정체성에도 깊이 뿌리닿아 있는 문제다. 이러한 의미에서 북항의 이슈와 함께 해항도시는 자신의 항구적 문화적 전통과 정체성을 어떻게 유지하며 발전시켜 나가는가라는 근본적이고도 광범위한 의문이 자연스럽게 제기된다. 본 연구에서는 이러한 논의의 확장과 심화를 위해, 독일 함부르크의 사례를 살펴볼 것이다. 함부르크의 슈파이허슈타트와 발린슈타트, 그리고 하펜시티는 도시를 의미하는 슈타트, 시티라는 명칭을 통해서 그 공간이 단지 하나의 건물, 장소에 머무르는 것이 아님을 암시하고 있다. 본 연구는 슈파이허슈타트의 경우는 함부르크 원도시와 일종의 제유법적 관계로서 읽고자 한다. 이러한 의미에서 슈파이허슈타트가 건설된 역사적 사회적 맥락을 논의하고, 이러한 맥락이 어떻게 공간적 시각적으로 확인될 수 있는가를 슈파이허슈타트와 원도심간의 교각을 통하여 확인해 볼 것이다.
