Tall building has some controversial aspects with low carbon city, but it is still a sensible choice for the metropolitan city. This paper aims to develop holistic urban design strategies to minimize impacts on the environment, increase energy efficiency and improve the quality of living in tall building communities by utilizing tall building characteristics. It puts forward the concept of integrated tall building-low carbon community design from the perspective of urban design, and summarizes five core strategies: Temporal state based on energy use, Complementary energy use state based on functions, Spatial state based on regional environment features, Transportation state based on low-carbon lifestyle and Waste utilization state based on tall building characteristics. It also applies the strategies to a practical project. The results show that the proposed urban design strategies are available approaches to mitigate the side effects of tall building on low carbon city.

The purpose of this research is to propose a plan on migration policy based on features, through analyzing the migration adaption process and the farming life of the back-to-countryside population throughout the nation. For this, survey has been conducted to find out urban-to-rural migrants' motives and characteristics. The major reason for the migration was the household's financial condition, and the most of migration decisions were made by either one's spouse or parents. The migration fund was primarily spent in early agricultural activities and it was the neighbors who aided them the most whilst teaching them many farming techniques. Some government-supported policies are being highly demanded regarding the lower level of income (than urban life) and difficulties of raising cultivation funds; these two things are what migrants consider as the most inconvenient and suffering matters in farming life. Many surveyee have responded that they would constantly stay in the rural area and continue on their life as a farmer, giving a promising prospect for future farmland life. Based on these trends and features, development strategy regarding elaborate settlement plan of urban-to-rural migration is necessary.

This study has a research objective to suggest detailed rules and principles to transcribe geographical names in English for English version electronic map service. For this, guidelines which are used in English transcription of local geographical names in Korea and English transcription situations of Korea geographical names in foreign electronic map service were examined. Examining results of current situations showed the English transcription method of home and abroad geographical names caused the chaos because it is not homogenized. In order to identify easy and preferred transcription method for foreigners among English transcription methods about the geographical names which are used together like this, the preference of English transcription methods of the geographical names was examined targeting foreigners. Survey results showed that foreigners prefer to transcribe in Roman character (Romanization) with its semantic word together than just to transcribe the Roman character. Reflecting this preference research results, our country's geographical names were classified as Natural features, Cultural features and man-made structures, and Administrative units and the detailed English transcription rules and principles of each geographical names were suggested.

Relying on the interaction indices - dominance index, relative strength index and entropy index, this paper analyzes the structural features of urban network in the Seoul metropolitan area with the flows of commuting, business, and freight. Analytical results show that the Seoul metropolitan urban system is vertical, size-dependent, one-way, and the highest city-dominant network rather than horizontal, size-neutral, two-way, complementary one. The network of freight flow is a little bit more symmetrical than the networks of commuting and business. However, the interaction with Seoul is still determinant in all aspects of hierarchical structure, relative strength, and symmetry of flow.

In urban environments, the surface land impermeability fundamentally related to urban growth emphasizes the environmental problems such as the storm water peak flow (so-called the urban flooding) and the pollution. The conventional urban drainage system provides a number of temporary reservoirs intercepting and retaining surface-derived pollutants following their introduction to and deposition upon the impermeable surface. Gully-pots are common features in urban drainage systems in Korea, which were installed for draining rainwater to prevent regurgitation in rainy season and retaining larger particles, hence minimizing pipe blockage problems. When the road runoff conveying sediment enters a gully-pot, the sediment mixes with the gully liquor causing direct pollution of receiving waters. The characteristics of local sediment contamination are usually related to the types of land use activities that take place or have taken place within the area., This study was undertaken to evaluate the spatial and temporal variations of the contamination of gully-pot sediments in Seoul with respect to heavy metals such as As, Cd, Co, Cr, Ni, Pb, Cu and Zn. The heavy metal data were examined according to the land use type. In this paper, sampling sites in Seoul were divided into six groups (commercial area, industrial area, residental area, motor way, rural area, and local pollution).

Reinforcement cells are used to aid grass growth and taken together, this serves to extend greenery beyond the conventional spaces of lawns, tree pits, gardens, and parks, and is advantageous to urban cities since space for greening is often limited. Drought has variable effects on plant life and the resilience of turf to drought resistance also varies with species. Changes in photosynthetic ability were more pronounced for media rather than grass species. The media of sand without organic matter was found to be least suited for drought resistance. Normalized difference vegetation index (NDVI) and digital image analysis (DIA) data were generally in favour of Zoysia species as oppose to A. compressus. In A. compressus, selective traits such as, a more extensive root system and lower specific leaf area (SLA) were not an underlying factor that assisted this grass with enhanced drought resistance. Generally, WUE was found to be strongly related to plant characterises such as overall biomass, photosynthetic features as well as the lushness indexes, and specific leaf area. This study found a strong relationship between WUE and a suite of plant characteristics. These traits should serve as useful selection criteria for species with the ability to resist water stress.

This study aims to develop a Flywheel Energy Storage System (FESS) that uses wind power produced when an urban train is in motion, by utilizing a mounted turbine. This system was designed to generate and store electric power from wind power of a travelling urban train. The flywheel was designed to continue rotation using a one-way clutch bearing installed in the turbine shaft pulley, even in cases where the urban train decelerates or stops. This FESS can generate an additional 44% of electric power in comparison to a system not equipped with a flywheel. The generated power and operational features of the FESS were evaluated and verified through a wind tunnel test. The results show that the electric power stored in the FESS could supply auxiliary power for urban train components or service equipment, such as charging mobiles, Wi-Fi modules, and electric lights.

The purpose of this study are to identify dimensions of leisure motivation of urban housewives. to segment hose wives according to their leisure motivation type and to find out the characteristics of each group. Sample of survey are 574 married women under age 60 living in Seoul. data collected by questionnaire and interview were analyzed through statistical method including factor analysis. ANOVA, Duncan test, MCA and cluster analysis etc. Major finding are as follows; 1) Urban housewives' motivation for leisure activity is composed of self-developmental, relaxatonal, social, family-oriented and imitational dimensions. 2) Main determinants of wives' leisure motivation are their age, education, job, stage in family life cycle. number of family members and household income. Their Sex role personality traits also have effect. 3) The urban housewives' leisure motivation is strongly correlated with their participation in leisure activity. 4) According to the factor scores of each motivation dimensions, subjects can be grouped to 4 typed by use of cluster analysis technique. They were named as Leisure-Indifferent type, Little-Leisure-Seekers. Passive-Leisure-Seekers and Active-Leisure-Seekers. Each of these groups showed different features in socio-demographic factors. different personality traits, and different leisure behavior. For and urban housewife, the most important need for leisure is developing herself. Rest. social life and family are important for leisure, too. Imitation is another reason. Groups with different combination of leisure motivation seem to have different resource and personality. These results have implication for futuer leisure plan for them.

In this paper, object-based classification of urban areas based on a combination of information from lidar and aerial images is introduced. High resolution images are frequently used in automatic classification, making use of the spectral characteristics of the features under study. However, in urban areas, pixel-based classification can be difficult since building colors differ and the shadows of buildings can obscure building segmentation. Therefore, if the boundaries of buildings can be extracted from lidar, this information could improve the accuracy of urban area classifications. In the data processing stage, lidar data and the aerial image are co-registered into the same coordinate system, and a local maxima filter is used for the building segmentation of lidar data, which are then converted into an image containing only building information. Then, multiresolution segmentation is achieved using a scale parameter, and a color and shape factor; a compactness factor and a layer weight are implemented for the classification using a class hierarchy. Results indicate that lidar can provide useful additional data when combined with high resolution images in the object-oriented hierarchical classification of urban areas.

This study tries to view the social and public roles of roads in urban structure in a renewed way, focusing on NakAn-Eupsung, which was a spontaneous settlement, not a designed city, of the many traditional villages. The most valuable meaning the alleys of traditional villages give us is the community of cooperation. Thus, this study tries to examine the features of the community in three major ways happening on the alleys of NakAn-Eupsung in three major ways. First, the features according to regional community; second, the features by social community; third, the features according to public community. Through this, we can understand the features of alleys within the building structure of traditional villages, and also we can have a chance to grasp the image of 'togetherness-of-the-public', long lost on contemporary alleys. In order to realize the ideal of sustainable residence, the techniques of housing complex project are continually being developed, and recently it is not hard to come across the flow of planning techniques taking especially community into consideration. At this point of time, it seems that various kinds of communities being made up on roads of traditional villages can present new directions and models to contemporary housing complex formation.
