  • As a result of an increase in population of the Metropolitan area and a steady change of circumstances in many parts, the city is sprawling out into the suburbs. This phenomenon causes the necessity of modification of present urban plan. It is risen as a point of issue that construction systems of new railway routes and underground construction, which should be followed the new urban plan in case of inter-regional railway and regional railway. It is hard to find sufficient financial resources, nevertheless the railway improvement definitely affects regional development and improvement of social environment. Also, there is a limit to government subsidies. In this respect, it is necessary to set up a new idea about movement of existing railway routes and improvement of the equipment. This study examines the present problems of railroad construction system in urban downtown area and introduces a suitable institutional way through referring to the instances of other countries.

  • It is required to response to the demand for new space due to high density of population and buildings in urban area. In particular, in case of big cities such as Seoul where the lack of new construction site due to the depletion of available space, existing buildings must be demolished for new construction. Utilization of urban underground space can be an alternative to solve for urban space problems. There are applications of underpinning methods using micropiles for existing buildings. Sometimes, the difficulties come from the compact space available for new foundation underneath the existing ones. In this paper, a novel underpinning method is introduced which can solve the space restriction problems underneath existing columns.

  • Building energy use estimation relies on building characteristics, its energy systems, occupants, and weather. Energy estimation of new buildings is considerably an easy task when compared to modeling existing buildings as they require calibration with actual data. Particularly, when energy estimation of existing building stock is warranted at a city-scale, the problem is exacerbated owing to lack of construction drawings and other engineering specifications. However, as collection of buildings and other infrastructure constitute cities, such predictions are a necessary component of developing and maintaining sustainable cities. This paper uses Artificial Neural Network techniques to predict electricity consumption for residential buildings situated in the City of Gainesville, Florida. With the use of 32,813 samples of data vectors that comprise of building floor area, built year, number of stories, and range of monthly energy consumption, this paper extends the prediction to environmental impact assessment of electricity usage at the urban-scale. Among others, one of the applications of the proposed model discussed in this paper is the study of urban scale Life Cycle Assessment, and other decisions related to creating sustainable cities.

  • Weak competencies in urban local bodies (ULBs) for implementing public private partnership (PPP) projects has been recognized as a major hurdle in uptake of PPP model in India. In this context, a questionnaire survey was conducted to evaluate perception of urban PPP experts and ULB representatives on three aspects related to competency development, including, critical competencies for implementing urban PPP projects, approaches for competency development in ULBs and constraints faced by ULBs in development of competencies. The five critical competencies identified are project identification, project conceptualization, transaction design, PPP process management and contract management. The approach of training programs for municipal staff and elected representatives, and capacity building oriented technical assistance for implementing urban PPP projects have been preferred by survey respondents for competency development. The frequent transfer of municipal decision makers and low motivation among municipal staff have been identified as the most significant constraints for development of competencies.

  • The purpose of this study is to review and evaluate the proper planning for 2030 Incheon Urban Parks & Green Space Master Plan. Some of the plans are aimed at multiple small districts within the city's old town, as local governments are planned to be sub-subsidized by Incheon Metropolitan City. However, these plans have become simple plans for each district and therefore find it difficult to collect from the perspective of the using system of the residents who are directly used. First, the construction of the urban park and green space network requires the construction of a service using system that can be felt by the users. Second, the basic idea of each district planned as the detailed strategy of the master plan should be planned through consultation with nearby the district. Third, specific targets and directions for the urban park and green space plan through the urban development project are needed.

  • The urban renewal type redevelopment project is a project to improve the urban environment for the recovery of urban functions and revitalization of commercial districts in commercial and industrial areas. Urban regeneration projects are not progressing smoothly. The urban renewal type is not so for landowners, who require a high level of professional knowledge and experience to carry out smooth projects. In addition, the core part of business conflicts can be seen as the problem of management and disposal methods. Therefore, as landowners, etc. become the actual subjects, the public will take charge of project execution, but all development gains and losses will be attributed to the owner of the land, etc.

  • As the urban development economy is stagnating due to the reduction of the budget for Social Overhead Capital (SOC) and the stabilization policy of the real estate market, there is a steady increase in the interest of domestic construction companies to enter the overseas market. However, domestic construction companies are showing a decline in overseas urban development market as compared with advanced foreign companies having excellent financial management and overseas project management ability. Therefore, it is necessary for domestic companies to select an urban development model that meets the environment and the level of the country of entry, and to establish an advance strategy to manage the risks of overseas business. For this purpose, the factors of entry into the overseas urban development market through the existing research, literature analysis, and FGI were derived, and survey strategy and IPA analysis were conducted to develop strategies for entering the overseas urban development market. As a result, we have established a strategy for private companies to enter the overseas urban development market.

  • The purpose of this study is to explore urban issues that have arisen in the urban growth process of the 1st New Town for about 34 years since its construction through newspaper articles. For this purpose, newspaper articles related to the 1st New Town were collected using web crawling, and content analysis was conducted based on text mining. The main findings of the study are as follows. First, in the early stages of the construction of the 1st New Town, issues were diverse in the following six sectors: living service facilities, real estate, transportation, urban development and maintenance, safety, and housing supply, but gradually narrowed down to those of real estate and urban development and maintenance. Second, during the new town construction and urban stabilization stages, the network structure centered on 'Seoul' was maintained, which can be explained by the fact that the 1st New Town was geographically located on the outskirts of Seoul, and many articles compared the issues to Seoul. Third, the issue of urban aging appeared from the 10th year after construction, and the discussion on urban reorganization due to urban aging began in earnest from the 30th year after construction. The significance of the study is that it explored the urban issues that occurred throughout the urban growth process of the 1st New Town, and can be used as a basis for preparing a plan to reorganize the 1st New Town.

  • Modern railway construction by Japanese had a great influence on the urbanization, transformation of urban structure and landscape during the Japanese imperialism and compressive increasing period in Iri(Iksan). This paper aims to find out the effect of railway on the modern urban structure and urban landscape in Iri(Iksan). Railways in Iri, Honam railway, Kunsan railway, Jeonla railway have been constructed progressively during 1911 and 1915 with Iri and old Iri(east-Iri) station. From the analysis of land registration maps and street plans, old photographies and historical records, some significant features underling railway construction can be followed in view of modern urbanization process in Iri. Firstly railways cut off the possibility of developing urban structure based on traditional spatial structure of Iksan. Secondly railways made dual spatial structure in Iri. Japanese and Korean life zone were divided into separate district around urbanization area and market place. Thirdly traditional space cognition system based on four cardinal directions were changed to front and rear space of railway station. Fourthly railways and stations caused neo-baroque spatial order and imperialistic urban landscape of Iri with axis, vista and gridiron plan. Fifthly break points and fringe belts garbling modern urbanization process are created. Sixthly modern cultural and consumptive urban spaces were taken their seats in relation with daily urban life.
