The purpose of the paper is to research issues and implications on a large-scale enlargement of urban area in city management plan. This study investigated laws and regulations in force and carried out case study for three cities such as Yangju-si, Gimpo-si, Whaseong-si. As a result of analysis, three points at issue were abstracted and improvement ideas for each of them were suggested as follows. First, to set up adequate size of urban area, it is necessary to consider resonable planning for population, spatial structure, zone of life and land use in city comprehensive plan and city management plan. Second, to decrease arguments about scope and bounds of urban area, it is important to make general and specific guidelines to set up them. Third, to manage new urban area and its surroundings efficiently, it is necessary to subdivide zoning of non-urban area strictly, to restraint individual location of factories or cattle sheds, to make a proper infrastructure plan in advance, to administer strongly the permission of development behavior and to control strictly consecutive and joining development in non-urban area.

This study aims to improve system for the enlargement of artificial planting spaces through grasp several problems about it and related system in domestic and foreign. In order to improve system for the extension of artificial planting spaces in the urban area following plans have been presented. First, it is necessary to launch various bonus, subsidies and incentives for making planting spaces in the urban area. Second, subdivision of related regulations for using diverse planting methods is needed. Third, government has to take the initiative in pushing on with planting of artificial spaces. Fourth, it is necessary to development of concrete techniques. Finally, it is desirable to plant artificial spaces which animal and plant can live, low effect to environment and material can be circulated although the value of plantation as a meaning of simple green also are admitted. Planting of artificial spaces should be introduced in a positive light for conservation and restoration of urban ecosystem.

This study was conducted to investigate the development of Gab river-basin which was a part of the farm land enlargement to contribute to the increased production of food. The results were as follows; 1. Gab river has the upper stream which occupy 50 percent in moumtains and the mid-stream in the Daejeon city area, and the downstream in a field which is about 22.9 percent in which farming area per household is 0.82 ha., agricultural population is 76 percent except of Daejeon city. Also, urban enlargement of mid-stream basin and development of industrial area in the lower stream diminish farm land. Consequently, this area should be developed to farm land to increase farming size. 2. There is no possibility to develop farm land in mountains of which (64.9 percent) is forests and in midstream which was constructed river-improvement. But Weonjeong area and Yongcheon area will be effective area. 3. If river banks of Weonjeong area will make straight with cost of construction 195,000,000 won, bank length 6 km will be useless, water will flow smoothly, flood will be prevented, farm land will develop 21.66 ha in which rice will produce annually 81.698 M/T which is about 10,860,000 won. 4. This area has good conditions of development. that is, investment efficiency (B/C) is 1.47 more than 1.00. 5. This area is a multiple purpose development district. The reasons are that there are beautiful mountains and a reservoir to be expected to construct, so it will be a sight seeing district in the vicinity of Daejeon city. 6. If Honam railway double line and river straight construction had executed simultaneously, cost of construction 50,000,000 won would have saved.

Logistics centers, distribution centers, or warehouse facilities increasingly dominate urban and suburban landscapes, their enormous but blank, repetitive facades completely overshadowing adjacent buildings. Mostly ignored by architects, this new building type symbolically represents the arrival of post-anthropocene, or post-urbicene era of architecture, in which an increasing portion of our built environment will not be intended for human occupancy, but rather for use by machines and artificial intelligence. As a new wave of logistics centers are becoming more automated, and more supersized, it is important to deepen architects' understanding of the organizational logic and programming factors that inform the overall design decisions for these facilities. With a particular focus on three case studies--Coupang, E-Mart, and Amazon Fulfillment Centers, this research examines the current trends in automation and expansion of logistics centers, and offers an analysis and forecast for future facilities in South Korea.

^x In Korea, we are entering on a new phase that the use concept of urban park is extending to dynamic activities such as games and sports. This article is to investigate the significance of lawn areas, as a receptive space of such a wide range of recreation activities. As a study process, Green Styles (type of parks) such as Garden Type, Park Type and Forest Type were studied and historical review of lawn areas in park development was performed. In conclusion, the lawn areas ( greensward) are an essential part of park and open space organization. The significance as a conclusion is presented as follows : 1 ) Balance in type of parks The structures of our parks and open spaces are inclined toward the artificial Garden Type and natural Forest Type. Therefore, the intermediate Park Type and sparse wood areas should be a core part of our park and open space development. 2) Psychological effect Park Type areas, thorned by greensward(lawn area), can refresh urban dwellers with natural picturesque landscaps, and Park Type landscape is the most preferred natural landscape. It shows the essence of natural amenity as 3) Accomodation of wide range of recreation activities Lawn areas in urban park are the best place in accomodating the wide range of active and massive recreation activities. Thus, lawn areas can increase the freedom of recreation use in urban park. 4) Enlargement of physical carrying capacity. With expansion of lawn areas of euro- american concept, the structural open space can be transformed into service open space. Thus, the recreation carrying capacity of urban parks can be enlarged.

This study measured transpiration rate of urban trees and albedos of urban surfaces, and examined the function of microclimate amelioration by urban greenspace. Transpiration rates of trees were highest in July and August of growing months. Transpiration per unit leaf area for the two months was 300-350 g/$m^2$/h for Platanus occidentalis, 210-270 g/$m^2$/h for Ginkgo biloba and Zelkova serrata, and 130-140 g/$m^2$/h for Acer palmatum. Surface albedos were 0.09 for asphalt paving and 0.68 for white wall, which reveals that light-colored surfaces are better than dark-colored ones to lower the heat build-up. Due to lack of evapotranspiration, concrete surfaces were, at t midafternoon maximum, 8$^{\circ}C$ hotter than grass ones, though the albedo of concrete paving was higher thant that of grass and trees. Summer air temperatures at places with 12% and 22% cover of woody plants were, respectively, 0.6$^{\circ}C$ and 1.4$^{\circ}C$ cooler than a place with no vegetation. To mitigate the impacts of urban heat islands, required are minimization of hard surfaces, light-coloring for building surfaces, and greenspace enlargement including more plantings.

Carbon dioxide is a major greenhouse gas causing climate change. This study quantified annual direct and indirect uptake of carbon by urban greenspace, and annual carbon release from vegetation maintenance and fossil fuel consumption. The study area was whole Chuncheon and Kangleung, and also two districts of Kangnam and Junglang in Seoul, cities located in middle Korea. Carbon uptake by urban greenspace played an important role through offsetting carbon release by 6-7% annually in Chuncheon and Kangleung. For Kangnam and Junglang, where the population density was relatively higher, urban greenspace annually offset carbon release by 1-2%. Future possible tree plantings could double annual carbon uptake by existing trees in urban lands (except natural and agricultural lands) of a study city. Based on study results, planning and management guidelines for urban greenspace were suggested to save energy and to reduce atmospheric $CO_2$ concentrations. They included selection of optimum tree species, proper planting location from buildings, design of multilayered planting, amendment of existing regulations for greenspace enlargement, avoidance f intensive vegetation maintenance, and conservation of natural vegetation.

Recently, many urban traditional houses have been replaced by villas and apartments for the inconvenience of lifestyle. The aim of this study is to survey the present distribution condition, research the extension and alteration, focused on Korean urban traditional houses in Cheongju which is the old city in an inland area, and inquire into the behavior patterns of an aged living alone livelihood and a large household. As a result, in the typical 'ㄱ' types of central inland houses, all the rear and side parts are nearly extended except facades facing court, while the detached houses for an aged living alones and tenants have enlarged rooms, kitchen and 'Daecheong' within the existing wooden framework. We could grasp the enlargement of room, 'Daecheong', corridor, and storage in the layout of the existing house. There are so many alterations such as the stand-up kitchen and a water closet. A new extension on an old house was intensely built for tenants.

The primary purpose of this study is to suggest the policy for the effective utilization of empty classrooms in elementary school. The empty classroom in this study means the classroom that is not used now since the number of students decreases, but can be usable for other needs in future. The following results are obtained through this survey; 1) about forty percent of classrooms are empty classrooms, 2) the ratio of empty classrooms is higher in urban area than rural area, 3) the smaller the size of classroom is, the higher the ratio is, and 4) 56.5% of the schools have one to three empty classrooms and 30.0% have four to six empty classrooms. In conclusion it is suggested that 1) the reutilization plan of empty classrooms be established according to particular situation of each school, 2) the government develop the guidelines for reutilization and administrative procedures for renewal, 3) the reutilization plan be established from the view point of the quality improvement of schooling, and 4) the enlargement and rearranagemt of learning space be considerd when reutilization is planned.
