  • In order to overtake a quantitative analysis of effect of anthropogenic heat and different land-use on urban thermal environment numerical simulation of surface energy budget was carried out under typical summer synoptic condition. It is beneficial to understand surface temperature of complex urban surace. The different land-use types are classified of rice field farm fruit garden residential region forest water and swamp by using map scaled 1/25000 of Pusan metropolitan. The model predicts that maximum heat island intensity in the central part of Pusan is 7$^{\circ}C$ at 2000 LST in summertime. The surface temperature is propotional to the density of constructions. The effect of anthropogenic heat generation on surface temperature is the increase of 0.3$^{\circ}C$ at 1400LST in the central part of Pusan during summertime.

  • Brownfield redevelopment is relatively a new area of interest for federal and local government in the U.S. In the past years, there are continuing interests by urban planners, policy makers and scholars in the effects of neighborhood amenities on brownfield. This paper intends to introduce brownfield redevelopment efforts and assess the approaches to implement such efforts by reviewing current federal legislation in the U.S. for brownfield, especially in the case of the Seattle Region. This paper provides an understanding of the brownfield phenomenon, statutory dilemmas, barriers and strategies of brownfield redevelopment. This paper also addresses the need of more policy adoption and implementation for successful brownfield redevelopment.

  • Due to increase in urban tunnelling as urban population and traffic volume increase, problems related with site security and civil appeal also increase. This paper presents a comparative analysis between conventional 2-arch tunnel method and non-pilot 2 arch tunnel method, which were performed in the basic design of Wie-Rae region. According to the analysis results, non-pilot 2-arch tunnel method is more efficient in terms of stability, constructability, and economic aspect. It is authors' wish that design procedure and method presented in this paper could help the design and construction of non-pilot 2-arch tunnel that should be planned in the near future.

  • The purposes of present study were (1) to examine the actual condition of wearing and purchasing Hanbok, (2) to investigate the effect of demographic variables on the wearing and purchasing Hanbok and (3) to identify the dissatisfaction with Hanbok. Data were collected from 702 females, age 20 or older, residing in Seoul, Taejon, Pusan and were analysed. Results of this study were as follows : (1) Korean urban women possess from one to three Traditional Dress and wear Hanbok in one to three during one year for special days. (2) The demographic variables that affect on wearing and purchasing Traditional Hanbok were age, income, family make-up and growing region. (3) One among the four Korean urban women possesses a Deformed Hanbok. And Korean women wears Deformed Hanbok for both daily life and special days. (4) The store that most women purchase Hanbok was order-made store near the house. The income affected on the store that purchaser selects significantly. (5) Three factors consisting of dissatis-faction with Hanbok were dissatisfaction with 'wearing', 'purchasing' and 'diversity of Hanbok design'. (6)Significant levels of correlations existed between the degrees of wearing Hanbok and the dissatisfaction.

  • This research aims to analyze the determinants of apartment rents in the Seoul Metropolitan area using spatial econometrics approaches. Since spatial econometrics approaches have advantages to solve limitations of ordinary multiple regression such as spatial dependence and spatial heterogeneity. This research includes structural variables such as number of rooms and baths, neighborhood variables such as number of housing units in the apartment complex, and location variables including distances to subway stations, to traditional markets, to educational institutes, and to urban services such as parks, etc. The result shows that the accessibilities to the CBD, to subcenters, to subway station, to school, and to parks contribute to apartment rent uplift and also shows different spatial variations in rent premiums by accessibility variables. In particular, apartments located south of Han river along the Lines 2, 3, 7 and 9 have the highest rent premiums due to the accessibility to the subway.

  • Urban quality of life(QOL) is recently considered as the important determinant of inter-urban migration and industrial location chice. However, there is little concensus in the method of measurement of QOL. This study provides an theoretical framework of the measurement of QOL. This study provides an theoretical framework of the measurement of QOL, and developes a new method, a multi-year$\cdot$mulit-dimensional distance index model. Based on the theoretical framework and the method, the QOLs of 74 urban areas in Korea are measured, and the determinants of the QOL and the changes of the QOL between two years of 1993 and 1995 are analyzed. The results of the analysis are as follows: 1) The interurban differences of the QOL tens to be interban differences of the QOL tend to be intensified over time. 2) The OQLs of the cities in the Capital Region are relatively deteriorated. 3) The conditions of education$\cdot$Culture$\cdot$leisure life determiner over 65% of the QOL of the Korean cities.

  • The diagnostic and prognostic methods for generating 3 dimensional wind field were comparatively analyzed and 4 dimensional data assimilation (FDDA) technique by incorporating Automatic Weather System (AWS) into the prognostic methods was discussed for the urban scale air quality model. The A WS covered the urban scale grid distance of 10.6 km and 4.3 km in South Korea and Kyong-in region, respectively. This is representing that AWS for FDDA could be fairly well accommodated in prognostic model with the meso${\gamma}$~ microa scale (~5 km), indicating that the 3 dimensional wind field by FDDA technique could be a useful interpretative tool in urban area for the atmospheric environmental impact assessment.

  • This paper discusses how urban regeneration can be used to drive economic competitiveness using the case study of Liverpool One, in Liverpool, United Kingdom. With a process which began in 1999, Liverpool One resulted in over 42 hectares of land being redeveloped as part of a wholesale rejuvenation of Liverpool City Centre. This contributed to Liverpool becoming the fastest growing UK region outside of London. In discussing Liverpool One, the paper outlines some of the planning challenges faced during its construction and what this successful regeneration project now means for those seeking to develop within the city centre, whilst drawing out some of the lessons international planners and developers might learn from Liverpool.

  • On the limited urban area, precise measurement of meteorological data is not easy for the cost problem. The facilities collecting the data require high installment costs. The mobile sources can be a solution in city region. For example, a public bus on which some meteorological sensors are installed can act as moving information gathering station. The information is gathered on a server and aggregated to generate useful information for smart phone application. To implement the services, several obstacles are exists. This paper studies on a design of this mobile meteorological information service system for urban area.

  • In order to use sea breezes to counter the heat island phenomena, i.e. to promote urban ventilation, it is necessary to clarify the effect of building morphology and height on large-scale wind fields. In this study, the sea breeze in the vicinity of the Kanto Plain in Japan is simulated using a mesoscale meteorological model incorporating an urban canopy model, and the inland penetration of sea breezes is accurately reproduced. Additionally, a mean kinetic energy balance within a domain (Control Volume; CV) moving along the sea breeze is analysed. From the results, it is clarified that the sea breeze is interrupted by the resistance and turbulence caused by buildings at the centre of Tokyo. The interruption effect is increased in accordance with the height of these buildings. On the other hand, adverse pressure gradients interrupt in the internal region.
