  • This paper introduces an overall system design of a real-time monitoring system that monitors condition of urban railway AC/DC transformers, disconnecting switches, circuit breakers, regulators, and GIS (gas insulated switchgear). For effective diagnosis of urban railway facilities we developed optimized sensors and application technology. The proposed system is combined with wireless technology, implementing remote real-time monitoring of urban railway facilities. The derived real-time monitoring system for power facilities in urban railway substations will be applied not only to diagnose low voltage DC (direct current) railways but also to diagnose design of small power facilities of skyscrapers and apartments.

  • After UNECD(United Nations Conference of Environment and Development) in 1992, ESSD (Environmental Sound and Sustainable Development) is an important concept of urban planning in Korea. The introducing environmental assessment system of urban planning and the district unit planning system were representative cases. In this process, Landchaftplanung(ecological landscape planning) was introduced from Germany. This study was executed for applying ecological landscape planning to Eunpyung New Town in Seoul city, and analyzing the problem to apply this system. The process of ecological landscape planning was followed to (1) the site survey, (2) the analysis and assessment of survey data, (3) the establishing ecological landscape planning. Three master architects participated in all investigations. The major fields of them were landscape architecture, architecture, and urban planning. Master Architects helped many aspects. In conclusion, ecological landscape planning was feasible to be applied to develop other New Town in Korea. However the mediation system is very weak, if different situations are confronted with ecological landscape plan and land use plan in the operative legal framework of Korea. Thus, the legislation of mediation system is necessary for an establishment of ecological landscape planning.

  • There are numerous plant and animal species which are adapted to the conditioins of the urban environment. The objectie of landscape and nature conservation in cities can be considered as the perservation of these organisms as the basis for a direct contact between urban dwellers and the landscape elements. However, after 1980 in Korea, green and biotope oases started to develop in the center of the urban area, from which the surrounding population benefited, at least indirectly. Thus urban biotope mapping and biotope informatioin system as a specialized tool of urban ecological landscape planning will make clear the orientation for the preservation of species and renaturalizing measures. The results are as follows : 1) Biotope types in the study area were separated to 21 biotope. 2) The written description of the biotopes took place on the computerized forms. The basis for the uniform inclusion and description of all biotopes surveyed was a codeplan. Additional details were included on the urban biotope mapping. 3) The evaluation of the mapped biotopes was completed to the following aspect, namely " species diversity and biotope conservation value" and "nature experience value". 4) UBM and BIS represent an important basis for decision aid for the city administration within the context of the ecological urban and landscape planning process. 5) The methodology of UBM and BIS in this study area could be extended to whole urban area.to whole urban area.

  • The purpose of this study was to analyze land use plans of 61 residential complexes and identify the factors that caused the variation of urban parks and green space ratio depending on the land ownership processing method. The ratio of urban parks and green space of expropriation districts was higher than that of replotting districts. Within the same city and country as well as other regions, the parks and green space ratio of land expropriation districts increased higher than 7% compared to that of replotting districts. The variation of urban parks and green space ratio was mainly related to the ratio of road. Small housing complexes such as detached house and quasi-residential sites resulted to expand space for road construction, thus, the areas of urban parks or green space came to reduce. The average urban parks and green space ratio in the urban development by the expropriation method and replotting method are 24.5% and 16.8% respectively. In order to prevent the reduction of urban parks and green space ratio according to the preference of detached house sites or quasi-residential sites in development zones, it is necessary to make systematic adjustment such as adjusting the urban parks and green space ratio securing standard.

  • The value of culture receives the attention of the world in order to solve urban problems and revitalize cities. Cultural city policies are implemented in Korea and EU to revitalize cities by utilizing cultural values. Although the cultural city policy is effective for urban regeneration, it has not been verified whether it has a positive effect in terms of urban identity and customer-based city brand. This study investigated whether cultural and artistic infrastructure and cultural artistry, which are resources of a cultural city, have a positive effect on urban identity, and whether urban identity affects the brand recognition and the perceived quality of a city. For this study, questionnaires were collected from 208 people residing in Seoul, and empirical analysis was conducted on 206 copies of them, excluding 2 copies of insincere answers. The infrastructure and cultural artistry of cultural and artistic resources showed significant results in the positive relationship between the cultural specificity of urban identity, social system and growth potential. Cultural specificity of urban identity also showed a significant positive effect on city brand equity. In the case of the social system and growth potential of urban identity, there was a significant positive effect on perceived quality, but insignificant results were found in the relationship with brand awareness. Through the results of this study, practical implications can be drawn for cultural city policy implementation and city brand management.

  • Background and objective: Urbanization caused a reduction in urban green space and a lack of community spaces. An attempt to solve these problems, urban gardens, have become popular and are currently being implemented in various downtown areas. However, urban gardens have some inadequate aspects from a visual or landscape perspective. The goal of this study was to examine the possibility of an aesthetic and productive garden space by introducing cultivation methods through the planting system design process. Methods: The design process using plants was classified and presented to suggest the importance of the landscape and aesthetic value. An urban garden space was designed according to the perspective of 'production scenery' and 'participation aesthetics'. According to the characteristics of the plant, urban gardens were divided into vertical type (corn, millet, sorghum), climbing type (kidney bean, cucumber, bitter gourd), and runner type (melon, watermelon, peanut). After classifying plants according to the shape of the root, the structure supporting climbing was installed and the crops were cultivated in an upright form with a tunnel. Results: In the designed cultivation, each crop cooperates, without invading each other's space. Compared with the conventional cultivation, there was little difference in production, and management was made more convenient since weed outbreaks were effectively suppressed while runner type crops cover over the land's surface. Since the positions of each crop are clearly distinguished, the aesthetic value is improved by offering a sense of rhythm with a balanced design. Conclusion: The results suggest that the cultivation methods through the plant system design process have aesthetic as well as productive value, and the design using plants, an infinite living resource, could lead to an expansion of the design field. Moreover, it would enable a sustainable symbiosis between industry and environment. There is potential for the design industry to make significant progress through collaboration with agriculture, horticulture, and landscape architecture.

  • This study aims to clarify the transformation of urban spatial structure around old castle in cheong-ju city. The urban spatial structure is composed with road system, block division, and lot system with original cadastral map in 1913 and 2011 GIS. Transformation of road system is classified into control of road line, construction and extension of road. Construction of arterial road was divided into Nam-juro and Mang-sunro with 2 blocks and lot system was destoyed. Transformation of block has not been developed except 4 blocks. The 4 blocks were divided into east-west or north-south direction and became 8 blocks. Transformation of lot system is classified into maintained, subdivided, and destroyed lots in shape and size of lots. Maintained lots were found in large lot in size for public office and park. Subdivided lots were mainly represented with the existing main road, an active alleys, and so on. Destroyed lots by road construction and extension were showed in Nam-juro. Although all these transformations are used to enhance urban spatial structure. The old systems have remained around old castle in cheong-ju city.

  • The purpose of this study is to provide a logical basis for guarantee the effectiveness of the tax support system, which is one of the main measures to prevent the side effects of commercial gentrification. For this purpose, this study analyzes the combination of tax support to replace the loss of net rental income due to stabilize commercial rents and annual rent increase rate that can be substituted through the tax support system based on economic utility of commercial lessors in Seoung-dong, Seoul. The result of this study shows that the tax support system can be used as an effective means to substitute a considerable portion of the net rental income loss due to stabilize commercial rents of Seongsu-dong. However if the rent price continues to rise every year, the tax support system does not work. In order to guarantee the sustainability of the tax support system, annual rent increase rate should be kept below a certain level.
