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.

The city of Sumqayit in Azerbaijan was famous in the USSR for its chemical plants, which supplied the whole country with plastics, detergents, and fertilizers. While production increased in the post-WWII period, young people from remote Caucasian villages were attracted as workers to the industrial settlement on the shore of the Caspian Sea and worked together with specialists from all over the USSR. Migration did not stop when the USSR collapsed. To the contrary, mobility increased as Azerbaijani refugees from Armenia and IDPs from Karabakh fled to Sumqayit, which grew to become the second-largest city of Azerbaijan. Although a generation has passed since the ceasefire, IDPs still are separately administered. In the last 20 years, more and more internal migrants have chosen the Greater Baku Region as their destination, mostly finding jobs in the informal labor market. In the post-independence transformative period, informal housing has offered migrants a place to stay in the city. Sumqayit can be regarded as an arrival city, an established urban platform for migrants who prefer internal over transnational migration.

The vacant houses commonly observed in urban aging are considered to be representative signs of urban decline. Vacant houses are themselves vulnerable to security, and in particular, they are exposed to disasters due to poor management, which can accelerate the decline of the area. This study is to classify the area and analyze the causes and characteristics of the occurrence of vacant houses by type based on the data through the survey on the vacant houses in Incheon. This research analyze vacant house data survey so to characterized and categorized types of vacant houses. The criteria of vacant houses analysis are population density, population growth, aging extent. In conclusion there are four types of region in Incheon area according to housing types, hazard classes, building age and building areas. Type A is inner city, type B is mixed, type C is expandable and type D is unsular types.

The main purpose of this study is to identify urban spatial structure by applying geographic information system and remote sensing data. This study identifies the urban spatial structure of non-megalopolis by analyzing the spatial distribution of population and employment in the case of Daegu metropolitan area. For this purpose, multi-temporal satellite image data (Landsat TM; 1995, 2000 and 2005) were utilized through the geographic information system. The distance-decay estimations in terms of population and employment density show that Daegu region as a whole shows monocentric urban characteristics. However, some evidences of polycentricism such as low explanation power of monocentric urban model, rises in multiple employment centers, decentralization of employment are emerging.

The purpose of this study is to build urban canopy model (Met Office Reading Urban Surface Exchange Scheme, MORUSES) based to Unified Model (UM) by using urban building information data in Seoul, and then to compare the improving urban canopy model simulation result with that of Seoul Automatic Weather Station (AWS) observation site data. UM-MORUSES is based on building information database in London, we performed a sensitivity experiment of UM-MOURSES model using urban building information database in Seoul. Geographic Information System (GIS) analysis of 1.5 km resolution Seoul building data is applied instead of London building information data. Frontal-area index and planar-area index of Seoul are used to calculate building height. The height of the highest building in Seoul is 40m, showing high in Yeoido-gu, Gangnam-gu and Jamsil-gu areas. The street aspect ratio is high in Gangnam-gu, and the repetition rate of buildings is lower in Eunpyeong-gu and Gangbuk-gu. UM-MORUSES model is improved to consider the building geometry parameter in Seoul. It is noticed that the Root Mean Square Error (RMSE) of wind speed is decreases from 0.8 to 0.6 m s^-1 by 25 number AWS in Seoul. The surface air temperature forecast tends to underestimate in pre-improvement model, while it is improved at night time by UM-MORUSES model. This study shows that the post-improvement UM-MORUSES model can provide detailed Seoul building information data and accurate surface air temperature and wind speed in urban region.

The nutritional status of 362 elderly men and women in Chung-bud area was evaluated in terms of their nutrient intakes, biochemical and anthrophometric measurements by interviews with questionnaires from August to October 1996. Mean intake of all nutrients except ascorbic acid did not meet the RDA for this sample. Protein, vit A, reboflavin, calcium were the most likely to be deficient on the basis of propotions of elderly consuming less than 75% of the RDA. The subjects nutrient intake was significantly affected by gender, marital status, number of family, family composition, educational level, pocket money, and region. Men in rural areas and women over 75 in urban areas were the most vulnerable groups with nutritional deficiency. According to serum biochemical indices, mean level of cholesterol, triglycerides, LDL, total protein, albumin and iron belonged to normal range but mean level of HDL showed below the normal range. More elderly men and women in urban areas showed a higher percentage of abormal level of cholesterol, triglycerides, LDL and HDL than those in rural areas. More elderly men and women in rural areas had abnormal levels of RBC, Hematocrit and hemoglobin compared to those in urban areas. Mean height and weight of elderly men was 161.4cm and 56.2Kg, respectively and 149.1cm and 50.5kg for women. The elderly in rural areas were taller than those in urban areas but had less weight, MAC, TSF, MAMC. Mean BMI of this sample belonged to normal range. However, the elderly in rural areas had a higher rate of underweight and lower for overweight than those in urban areas. The elderly in urban areas had higher blood pressure than those in rural areas.
