High-rise as a building typology is gaining popularity in Asian mega-cities, due to its advantages in increasing volumetric density with limited land resources. Numerous factors contribute to the formation of high-rise urban form, from economical and institutional, environmental to socio-political. Environmental concerns over the impact of rapid urbanization in developing economies demand new thought on the link between urban environment and urban form. Outdoor and indoor climate, pedestrian comfort, and building energy consumption are all related to and impacted by urban form and building morphology. There are many studies and practices on designing individual "green" high-rise buildings, but far fewer studies on designing high-rise building clusters from the perspective of environmental performance optimization.. This paper focuses on the environmental perspective, and its correlation with the evolution of the high-rise urban form. Previous studies on urban morphology in terms of environmental and energy performance are reviewed. Studies on "parameterizing" urban morphology to estimate its environmental performance are reviewed, and the possible urban design implications of the study are demonstrated in by the author, by way of a microclimate map of the iconic Shanghai Xiao Lujiazui CBD. The study formulates the best-practice design guidelines for creating walkable and comfortable outdoor space in a high-rise urban setting, including proper sizing of street blocks and building footprint, provision of shading, and facilitating urban ventilation.

Most of construction at urban area is now undertaking a redevelopment because currently the most of city is full. But the research about the collision of urban tissue at urban redevelopment area are very limited and there are many issues at urban redevelopment area. So the purpose of this study is to analyze the collision between different urban tissue at urban redevelopment area and suggest proper method for urban redevelopment. The area inside of four main gates, especially Chung Jin, Gong pyeong, Mu gyo- Da dong district are selected to analyze because the area inside of these gates is the oldest urban redevelopment area and each of them has a different redeveloped method. And current status of research area's urban tissue and collision situation are analyzed by macro and micro scale of view. The results of this study were as follows; Ignoring the timeline of the urban redevelopment process can be a major issue in collision between urban tissue. Therefore, the consideration of intermediate stage of redevelopment process is needed by making public area, a temporal use of vacant lot and changing architectural elements can make a harmony between different urban tissue.

This study examined importance and performance of urban agriculture education program of the trainees who attended urban agriculture education, and suggested reformation of urban agriculture instructor course of Gyeonggi Provincial Agricultural Research & Extension Services by IPA models. The investigation was done on October 7, 2011. The subject was 40 trainees of urban agriculture instructor course of Gyeonggi Provincial Agricultural Research & Extension Services. The study suggested reformation of urban agriculture education program based on the findings as follow: Firstly, the instructors should teach trainees not theoretically but practically to let the trainees make use of learning at urban agriculture. Secondly, teaching material that is not theoretically but practical enough to apply it to actual urban agriculture should be supplied. Thirdly, urban agriculture education should be done not theoretically but practically considering its characteristics. Theoretical contents have been already included in teaching material, and practice oriented education should be done to let trainees put theory into practice on-the-spot. Practice oriented education should be supported in the planning future education. In addition future urban agriculture education program should consider importance as well as practice of educational contents, lecturers, operations and facilities.

The necessity of urban regeneration is recently increasing because of the deterioration existing urban area and the slowdown of new development operations. The urban regeneration is differentiated from other private operations by its public characters, which is the basis of public support. This character demands verification of the adequacy for public finance support by monitoring urban regeneration planning and operation. Therefore, this study aims to show the monitoring indicators and its application in legal system for urban regeneration through the examination of foreign countries cases. London, San Francisco, and France urbanism regulation and planning system show the measure for introducing urban regeneration monitoring system into korean urbanism institution. This study is significant by suggesting the circulation structure of urban regeneration by linking planning, operations and monitoring phases. The monitoring system permits improvement of urban regeneration by clarifying objects and ameliorating efficiency by continuos observation and application of its evaluation.

Modern cities need to revitalize the downtown area, which is declining due to population decline, economic recession, and deterioration of the residential environment, economically, socially, and physically by introducing and creating new functions. In addition, the hollowing out of the existing city center is getting worse due to the development of the outskirts of the city. Therefore, the discussion for the development of urban regeneration is the core task of modern cities. This study analyzed based on a basic understanding of urban regeneration projects, and through this, the problems of domestic urban regeneration projects were derived. In addition, the problem factors and major improvement plans of the urban regeneration project were analyzed from the expert's point of view using the AHP analysis technique. Based on this, the purpose is to present policy alternatives for the future development of urban regeneration projects. The problems derived to present the policy alternatives and improvement directions of the urban regeneration project were classified into problems related to goal achievement, problems related to the business itself, and problems related to project results. It was subdivided into sub-categories. This study analyzed the problem factors and major improvements from the expert's point of view by using the AHP analysis technique for the problems of the urban regeneration project. Based on the AHP analysis results and experts' opinions, five policy alternatives for the development of urban regeneration projects were presented.

After 1960s, a radical change was taken place in the modern urban theories which were developped by many architects and planners like Ebenezer Howard, Tony Garnier, Le Corbusier, Ludwig Hiberseimer, and Patrick Abercrombie. Many contemporary architects like Kevin Lynch, Aldo Rossi, Christopher Alexander, Colin Rowe, Rem Koolhaas, and Bernard Tschumi have a view that modern urban theories lost their abilities to organize and control new realities so that new urban theories was needed in order to cope with urban problems in the 1960s. In this study, we are to examine contemporary urban theories in comparison with modern urban theories and to clarify the role of discourse of language in its emergence. In consequence we can detect four main themes in the process of transformation from modern urban theories to contemporary urban theories : from functionalism to formalism, from historicism to archeology, from space to placeness, and from hierarchical organization to network. And we can prove that such themes basically depend on the discourse of language.

This study explores potential capability of a machine learning approach for monitoring urban morphology based on an evident case study. The case study conveys year 2006 investigations on interpreting urban morphology of Boston Main Streets by applying a machine learning approach. From the lesson of the precedent study, in 2016, another field research and interview was conducted to compare changes in urban situation, data commons culture, and technology innovation during the decade. This paper describes open possibilities to advance urban monitoring for morphological changes. Most of all, a multi-participatory data platform enables managing urban data system in real time. Second, collaboration with machines with artificial intelligence can intervene the framework of the urban management system as well as transform it through new demands of innovative industries. Recently, urban regeneration became a dominant urban planning strategy in Korean, therefore, urban monitoring is on demand. It is timely important to correspond to in-situ problems based on empirical research.
