  • This paper discusses major strengths of tall buildings that distinguish them as sustainable solutions for the built environment. It sheds light on some of the key attributes of tall buildings as well as materials and technologies that could boost their performance environmentally, economically and technically as well as the natural habitats containing them. Tall buildings are portrait as major successful options for accommodating the ever increasing urban world population, with little negative impact on ecologies and environmental habitats worldwide. The role of tall buildings as 'vertical garden sub-cities' mitigating modern city problems of 'urban heat islands' and sprawling cities is explored. A few building examples as well as city developments are presented which represent the new generation of sustainable tall buildings that are setting trends for future projects incorporating innovations in materials and building systems and designs.

  • Rainwater runoff has been identified as a significant source of contaminants having tremendous impact on the receiving aquatic environment. In the present study, trace element transport by the surface runoff in the predominantly urban catchment of Guwahati city, India was monitored with a view to determine the chemical denudation rates of the land surface. A number of trace metals, namely Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn were measured in the runoff after 70 major rain events within the city. Cadmium was found to be the least abundant metal and Iron was the most abundant metal in the runoff. The results are interpreted on the basis of temporal and spatial variations in their concentrations. These variations are quite large in some of the events and reflect changes in the local environmental setting, differences in water utilization, variations in runoff volume, gradient and quality.

  • As a rise in national income has resulted in the growth in tourism demand, many studies on developing and managing tourism resources were publicized. In this context, this study was conducted to analyze the demand and willingness to pay(WTP) using contingent valuation method for agricultural experience of Daegu Urban Agriculture Park and to suggest a proper participation fee. The survey targeting Daegu citizens was performed, and we obtained 346 valid samples. We carried out the logistic analysis and figured out that sex, age, education and alienation area for urban agriculture affected to probability of agricultural experience participation. As the result of estimating willingness to pay(WTP), the measured range with this samples was from 6,052 to 16,436won. Finally, we also attained 25,000won as the proper participation fee which enables maximum revenue by conducting the scenario analysis. These findings are important in setting up the construction plan and pricing the appropriate participation fee for Daegu Urban Agriculture Park.

  • The purpose of this study is to present an appropriate approach to urban regeneration by analyzing Gwangju Metropolitan City. For the study, residential area of Asia Culture Complex was analyzed based on GIS. The areas concerned were categorized and looked into by their Situation based on the analysis of urban infrastructure state. However, as the architectural space within a city are limited, and accurate assessment of them is needed. The residential areas have the following characteristics. They become an aging and dilapidating residential and socially underprivileged-concentrated area. It is necessary to set up a direction for a future-oriented planning for the development of these areas. Along with a decreasing population, it is important to improve the urban architecture environment for the elderly in an aging society. The economic growth of a city if necessary for the future. Therefore, the criteria for the assessment is required. And the subsequent setting-up and planning of a future direction for a city is badly needed. After that, an accurate assessment of a city called for. City space allows for various interpretations. As the rich are getting richer and the poor are getting poorer, a wealth is concentrated on one district or an area.

  • This study aims at drawing implications for Korea's urban growth management policies from U.S.A's experience on this issue. This study analyzes two types of contradictions in planning and implementing urban growth management policies: 1) value conflicts in goal setting and 2) contradictions among different level of governments (local, province, nation). As mentioned by Campbell (1996), there are three types of conflicts in objective values (efficiency, equity, and environment protection): property contradiction between economic growth and equity, resource conflict between efficiency and environment protection, and development conflict between equity and environment protection in urban growth management policies. In implementing urban growth management three types of conflicts in goal values should been taken into consideration. Contradictions among local governments, province, and central government are also found in implementing growth management policies. The lessons from the United State are as follow: 1) growth management plans are initiated by the local government and during the planning process adjacent local governments review a local government's growth management plans and give inputs for the plan, 2) local government and State work together for growth management planning and specially, the State provides technical and financial assistance to local government, and 3) the State plays leading roles in local government's planning and implementing of growth management policies with carrot and stick policy.

  • This study aims to provide basic data for planning the supply and demand of urban parks and setting up facilities in urban parks that reflect the use patterns of visitors. The study was conducted by surveying the total number of urban park users and the number of users for different time zones and analyzing their use patterns through on-site surveys at 17 urban parks located in seven cities/counties in Gyeonggi province. The result showed that as for distribution of urban park users by time zone, the number of users was highest in the afternoon. Between 7 and 9 o'clock in the morning in weekdays, many users came to urban parks for their morning exercises. There was hardly no difference between male and female. When the number of users of 17 urban parks was surveyed, a park was used by 734 people per day on weekdays in average. When the total number of users per year was estimated, a resident nearby a park visited the place 4.7 times a year in average. In addition, the analysis showed that the number of users of man-made parks was twice as high as that of natural parks. The number of users did not vary depending on the size of a park. As for use patterns by time zone, no difference was found in activity types between parks larger than 100,000 $m^2$ and those less than 100,000 $m^2$. Usually, in the morning, users came for exercises In the afternoon, users visited the parks for more diverse purposes. In the evening, they tended to visit parks to work out and wrap up a day. Going forward, the outcome of this study should be utilized as important data for analyzing the demand and supply of urban parks. In addition, the number of users by time zone and their use patterns should be fully considered when introducing facilities in parks.

  • The purpose of this study is to understand the social welfare approach and to suggest implications for the establishment and expansion of social welfare techniques in recent urban regeneration to overcome the limitation of physical approach to urban regeneration. We used the method of the content analysis to extract social welfare programs in project plans of urban regeneration regions and vulnerable residence regions and then let them be categorized according to characteristic and form of their programs. As a result of the analysis, there are 4 welfare programs in urban regeneration regions; setting the economic fundament, improving the residential environment focusing on welfare, pursuing community integration and social service providing. And each type was classified into 12 subtypes. Based on the result of this study, some implications are suggested to operate social welfare techniques in a stable manner in urban regeneration projects; link of the suitable jobs for regional characteristics, the participation of local residents in the project process, empowerment for community integration and expanded provision of social services.

  • The urban railway station is a structure that consumes a large amount of electric energy. Thus, the rationalization of using electric power is acutely demanded, but statistical data and design criteria that consider operating power load characteristics and structures, are very insufficiency. Therefore, this study investigated and analyzed that electricity consumption a year, characteristics, gross floor area of the station, structure, and etc, on the basis of Seoul metro station 1~4 line. Through regression analysis theory, we verified the overall features and the main tendency by analysis of specific parameter value(average, maximum, minimum, etc). The object of this study is the analysis about power density considering structure of the urban railway station, managing electric energy for the rationalization and setting a new standard of maintenance and construction.

  • This research focuses on accomplishing analysis problems and issues by examining the policies and systems related to geo-spatial big data which have recently arisen, and suggests political and systemic improvement plan for service activation. To do this, problems and probable issues concerning geo-spatial big data service activation should be analyzed through the examination of precedent studies, policies and planning, pilot projects, the current legislative situation regarding geo-spatial big data, both domestic and abroad. Therefore, eight political and systematical improvement plan proposals are suggested for geo-spatial big data service activation: legislative-related issues regarding geo-spatial big data, establishing an exclusive organization in charge of geospatial big data, setting up systems for cooperative governance, establishing subsequent systems, preparing non-identifying standards for personal information, providing measures for activating civil information, data standardization on geo-spatial big data analysis, developing analysis techniques for geo-spatial big data, etc. Consistent governmental problem-solving approaches should be required to make these suggestions effectively proceed.

  • The rising urban space in the United States at the turn of the twentieth century was an exemplary site of struggles between the dominant white population and those who migrated from the imperial peripheries. By setting up the space of Chinatown as a segregated sphere within the urban space, the dominant white American society attempted to recreate the sense of distance between themselves and the racial "others." Accordingly, the dominant narrative representations of San Francisco Chinatown at the turn of the century endeavored to produce and maintain the spatial dichotomies between the orderly spaces of natives and the disruptive immigrant communities within the larger boundary of modern American city space. As a Eurasian woman writer, Sui Sin Far attempted to provide distinctive portrayals of the space of Chinatown and its inhabitants that were far different from those of her contemporaries. Through her portrayals of San Francisco Chinatown in her collection of short-stories, Mrs. Spring Fragrance and Other Writings (1912), Far challenges against the false stereotypes and misreading of this unique immigrant space within and efforts to present the Chinatown as a heterotopic diaspora space where the "insiders" and the "outsiders" of the American urban space intermingle and influence each other.
