The purpose of this study was to understand changes in Seoul's downtown planning from the 1960s to 1990s. The approach was examined by classifying its formation process though urban conservation. The effects of modernization and urbanization on Seoul's downtown planning were as follows. In the 1960s, Seoul attempted to decentralize urban functions due to excessive population. In the 1970s, a policy to diversify urban functions according to Gangnam development was enacted. In the 1980s, the existing downtown declined, and the sub-downtown grew with changing urban functions. In the 1990s, the identity of the existing downtown was recognized through the Seoul Memorial Project. This study also analyzed downtown planning efforts concerned with urban conservation. First, the physical aspects of existing buildings and street facilities were maintained. Second, the spatial aspects for the maintenance of surrounding areas were proposed. Fourth, the social aspects for accessibility by Seoul citizens was improved. This analysis demonstrates the concept of urban conservation based on physical-spatial-social aspects.

This paper is to analyze citizens' consciousness on urban changes, especially focusing on changes in urban environment, spatial structure, and urban planning, of large cities in S. Korea, that is, Seoul, Daejeon, Daegu, and Kwangju in the 1990s. Some significant points can be described as follows. First. The most important factor influencing on the change of urban spatial structure was the expansion of residential area inner and outside of cities promoted by the traditional construction industry, and not development of high-tech industries and their complex or location of multi-national firms which can be emphasized as major factors of new urbanization process of global cities. Secondly, citizens seem to have experienced improvement and deterioration of urban environment simultaneously, emphasizing regulatory environmental policy on the one hand, and recognize the necessity of sustainable urban development within given environmental capacity and restoration of destructed and polluted environment of cities. Thirdly, the building boom of new apartment complex was a major driving force of changing urban spatial structure, but it could neither alleviate a residential gap between the poor and the rich areas nor a relief of traffic congestion. Finally, the urban policy in general was felt somewhat improved by citizens, but not in sectoral details.

This paper is to analyze citizens' consciousness on urban changes during the 1900s in the sectors of economy, politics and socio-culture of large cities in Korea, especially comparing them in Seoul, Daejeon, Daegu, and Kywangju. The items of questionnaire are drawn from theories on each sector of new urbanization of large city in Western countries, that is, that of post-Fordism, of urban governance, of post-modernism, and of sustainable city. Some major findings of this questionnaire analysis are as follows. First, on the change of large cities in general, citizens think that the sectors of spatial structure, and of socio-culture of the cities were changed more than those of urban economy and of urban politics. Secondly, in the sector of urban economy, citizens recognize that the obstructing factors of development, that is, the lack of regional capital and the absence of head-quarter of large firms, which seems to be resulted from uneven regional development in the previous periods were much more serious than others, while acknowledging the importance of high-tech industry. Thirdly, in the sector of urban politics, citizens think that the centralized structure of politics and of political parties was still problematic, while acknowledging the importance of entrepreneur mind of urban governor. Finally, in the sector of urban socio-culture, citizens emphasize the development of telecommunication, the popularization of private automobile and the increasing use of credit card, as three major factors which have exercised major impacts on the development of urban socio-culture.

As urban growth continues, the earth ecosystem is increasingly dependent on the patterns of urban growth. The impact intensity from urban growth is expected to change predictably with distance from the urban center. However we can't fully understand yet how urban development pattern affects urban ecosystem. In researches about urban ecosystem, it is important to relate the spatial pattern of urbanization to ecological processes. So we used gradient analysis with time data; 1980's, 1990's and 2000's. We attempted to quantify the urban spatiotemporal impacts in Daejeon-city and Cheonan-city, Korea, along a 75km long and 3km wide transect. Through the results, we found the impacts range of urbanization with urban development process of two cities. When the urban growth was concentrated on in both cities, the impacts intensity and range were much stronger and wider. As a result, in urban planning or green space planning, we have to consider suitable urban development forms with surrounding areas, and make legal clauses which limits landuse change. This quantifying the urban gradient is an important step in understanding urban ecology.

This study analyzed the spatio-temporal change detection of land-use and urbanization in Yongin and Anseong regions, Kyunggi Province, using three Landsat-5 TM images for 1990, 1996, and 2000. Remote sensing (RS) and geographic information system (GIS) techniques were used for image classification and result analysis. Six land-use types were classified using supervised maximum likelihood classification. In the two study areas, the land-use changed significantly, especially the decrease of arable land and forest and increase of built-up area. Spatially, the urban expansion of Yongin region showed a spreading trend mainly along the national road and expressways. But in Anseong region the expansion showed 'urban sprawl phenomenon' with irregular shape like starfish. Temporally, the urban expansion showed disparity - the growth rates of urbanized area rose from the period 1990-1996 to 1996-2000 in both study areas. The increased built-up areas were converted mainly from paddy, dry vegetation, and forest.

Recently, the space organization of Korean-Chinese houses is different from that of other territories. The vast land of China, coming from different hometown in Korean peninsula, and the different hometown in Korean peninsula, and the different procedure of settlement seem to make the different space organization of Chinese-Korean single family housing at the urban area in Liaoning Province.The characteristics of the Korean-Chinese space organization of single family housing at the urban area in Liaoning Province are as follows;i)Three types of space organization are central kitchen type, central corridors types, and central living room type. ii)The central kitchen type is mainly in old urban housing, after 1980's, the central corridor type appears in single family housing, and central living room type appears 1990's.iii) It seems that the main reason to change the space organization are fuel, system of heating, influence of Korea housing. Especially, Korean-Chinese like central living room type that is suitable for sit down living style. This central living room type supposes to be used as popular space organization in urban housing.

Existing buildings in urban parks are a kind of thing that has been settled and occupied on the site of an unexecuted park. The aim of this study is to identify nature by analyzing the causality and path-dependency through the transformation of the relevant system. The scope of the study was set up as a system for the occupancy of urban parks from 1934 when the building restriction system was established to 2000 when purchase claim (매수청구권) was introduced. The method of study was to get correlation by harmonizing the external and internal mechanisms affecting the relevant institution. The related system showed a modest change in the fourth stage, polymerizing the initial system. In the 1950s and 1960s, the existing buildings in urban parks were 'disguised' by government and the 'regulation' principle was applied since 1967. In the 1980s, the principle of 'protection' and 'support' for parks was added, but in the 1990s, the principle of regulation began to be lifted as the long-term unexecuted urban park (장기미집행 도시공원) problem continued for more than 60 years. Although the public concept of land ownership (토지공개념) has worked strongly for nearly 30 years since 1960, the system has developed into a form of deregulation since 1980. The nature of the relevant institution is first, dependent on the higher-level system and vertical. Second, it implies a conflict of restrictions and acceptance. Third, it is a temporary measure of the park problem. Therefore, the relevant system has long been enhancing the encroachment requirements on urban parks, so fundamental readjustment is needed in the future.

It was analyzed climatic data in Gimje, Buan, Iksan and Jeonju in Jeonbuk Province between 1930s and 1990s. The data source of Gimje and Iksan in 1930s were Namseon Agricultural Experimental Station. Those in 1990s was Honam Agricultural Research Institute, Rural Development Administration. The data source of Jeonju of 1930s and 1990s was Jeonju Weather Station, Korea Meteorological Administration. Weather Station of Gimje and Buan were located at the agricultural area in rural paddy field. That of Iksan was located at the agricultural area in suburban paddy field. That of Jeonju was located at the downtown area. As compared to mean air temperature between 1930s and 1990s, it was increased by $0.2^{\circ}C$ in agricultural area, $0.6^{\circ}C$ in Iksan city and $1.4^{\circ}C$ in Jeonju city. On the while, increased temperature was the higher in winter than other seasons. Annual precipitation was increased by 128.1 mm in agricultural area and 169.3 mm in Jeonju city. And it was remarkable in summer season.

This paper aims to examine from various perspectives how domestic research studies and projects related to climate change have been conducted to mark the 60th anniversary of the Korean Meteorological Society (KMS). The 『50-year History of the Korean Meteorological Society』, published more than a decade ago, has never dealt with the history of development of individual fields of meteorology such as climate change. Therefore, it is of significance to look at the history of research activities and studies achieved by KMS members in the area of climate change over the past 60 years. The research on climate change in KMS is classified by era from the beginning to the latest and the contents are examined by major research projects at that time. During the past 60 years, climatological research in KMS has been mainly focused on general climate, synoptic climate, and applied climate (urban climate) until the 2000s. However, since the 1990s, climate change has become an important area for climate research. The 2000s are the beginning era of climate change research, since the major projects and researches for climate change has begun in the period. The 2010s can be a time when climate change prediction and monitoring are expanded and refined to meet the rapidly increasing demands for climate information from a wide range of areas. We concluded that the development of the research capabilities of the society over the past 60 years, in particular in the past two decades, in the field of climate change research is remarkable.

Nowaday special attention is being paid to the conservation of all species or ecosystmes of sites for public projects. Many environmental conservation policies and projects in Japan emphasize the coexistence of man with nature and close contact with nature. The objectives of this study was to investigate policies and projects for the creation of areas for the close contact with nature in Japan, to characterize change of techniques for the space creation over times, and to classify those policies and projects implemented by many government agencies. This study was mainly carried out by literature survey of laws, policies and projects related to environmental conservation pertinent to national scale. Major findings of this study can be summarized as follows: First, two most significant turning points for the environmental conservation in Japan were the establishment of the Office of Environmental in 1971 and the enactment of many laws influenced by the awareness of global environmental problems since 1990. Second, polices and projects for the creation of areas for the close contact with nature started in 1960s by the Office of Forestry, and focused on planting and development of simple facilities in forests. And the conservation of natural environment, ecological restoration and the expansion of urban green spaces, and the creation of biotopes and other areas for the close contact with nature in urban areas were the major characteristics of environmental conservation in Japan during 1970s, 1980s, and 1990s, respectively.
