If a new utility tunnel is planned for high density existing urban areas in Korea, a rational decision-making process such as the determination of optimum design capacity by using the feasibility evaluation system based on quantitative evaluation indexes and the economic evaluation is needed. Thus, the previous study presented the important weight of individual higher-level indexes (3 items) and sub-indexes (16 items) through a hierarchy analysis (AHP) for quantitative evaluation index items, considering the characteristics of each urban type. In addition, an economic evaluation method was proposed considering 10 benefit items and 8 cost items by adding 3 new items, including the effects of traffic accidents, noise reduction and socio-economic losses, to the existing items for the benefit cost analysis suitable for urban utility tunnels. This study presented a quantitative feasibility evaluation method using the important weight of 16 sub-index items such as the road management sector, public facilities sector and urban environment sector. Afterwards, the results of quantitative feasibility and economic evaluation were compared and analyzed in 123 main road sections of the Seoul. In addition, a comprehensive evaluation method was proposed by the combination of the two evaluation results. The design capacity optimization program, which will be developed by programming the logic of the quantitative feasibility and economic evaluation system presented in this study, will be utilized in the planning and design phases of urban community zones and will ultimately contribute to the vitalization of urban utility tunnels.

To classify the relationship between riparian vegetation type and bird habitat, we studied the vegetation and avian species in the three streams(Anyang Stream, Gap Stream, Seom River), located in middle province. Five different vegetation types - Woodland type, Shrub type, Tall and wet grassland type, Low and dry grassland type and Cropland - were identified. The habitats of avian species were highly correlated with vegetation type. Streptopelia orientalis and Hypsipetes amaurotis were found in woodland. Both Paradoxornis webbiana and Phoenicurus auroreus were mainly found in shrub. Tall and wet grassland were preference habitats of Ixobrychus sinensis, Acrocephalus arundinaceus, while, low and dry grassland were occupied by Phasianus colchicus, Falco tinnunculus. Cropland were used as breeding and feeding sites for Egretta alba modesta, Anas poecilorhyncha, Anthus spinoletta. Distribution patterns of avian species were clearly divided by vegetation type and site characteristics in the stream.

This study aims to draw a Housing development scheme of elderly housing, including the urban, suburban and resort type according to location type, which is based on a Demanding Characteristics of preliminary elderly for elderly housing. In addition, The comprehensive implication tells that the preliminary elderly who wants the urban elderly housing type have a more personal characteristics than other types. So it should be considered according to personal characteristics. Next, when we choose the suburban elderly housing type and predict the demand for housing development, it should not only considers factors such as the Unmarried children, Health status, Current housing size and Plans for economic activity in old age but also considers factors such as the Accessibility, Convenience, Investment and Environment characteristics of elderly housing preference. Next, when we choose the resort elderly housing type which based on the fact that a few detailed parameters of current housing characteristics exist, it should be based on the current housing characteristics of preliminary elderly. In addition, it should consider a pre-investigation for elderly housing preference in order to select the housing type. Because a comprehensive preference such as the comfort, convenience, safety, investment, environmental characteristics is considered as major determinants factors.

The aim of this study is to analyze tthe pattern of compacted area and the distribution characteristics in one-person household. Through ArcGis, we collect the basic data and classify the compact area in accordance with the pattern employing Ward method out of cluster analysis. The main results are found as follows; First, the station sphere type is located around Seomyun and Nampo-dong, which are the main CBD( Central Business District) This type must be essentially considered in residential plan for one-person household location. Second, the district oriented type is located around the subway and it has relatively better residential facilities and environments. Third, it is found that the younger worker including students resided in one room and villa in the type around university. Forth, the foreign workers and domestic workers in small and medium factory resided in the factory centered type which is far from the station sphere. Lastly, it is dormitory type which is isolated from the CBD, and insteadly amenable and well natural environment area, but students and workers in this area where there are lacking life-related facilities and aside from accessibilities feel uncomfortable.

The purpose of this study is to present the problems of urban ecosystem imbalance in Seoul and the need to restore housing functions through comparison with Manhattan, New York, which grew earlier than Seoul and has been striving to solve urban problems and restore urban ecosystems. The residential status in urban commercial use areas was investigated through analysis of the total amount of residential space, characteristics of each type of residential building, and distribution of residential buildings. Through this, it can be seen that most of the space in Seoul's historic city center is biased toward commercial roads, and there are significantly insufficient high- and high-density mixed-use buildings suitable for urban dwellings compared to Manhattan's. In addition, it can be seen that the complex building in the historical city center of Seoul is located adjacent to the outskirts of the target site. In conclusion, Seoul's historical city center does not provide an appropriate residential space for creating an urban ecosystem, and it is necessary to come up with measures to restore housing functions.

In this study, a fundamental-level study was performed to establish knowledge-base for the development of optimal surface-wave method for urban areas with adjacent structures. First, theoretical modelling was performed to investigate the influence of adjacent structures on dispersion characteristics of surface waves. Later, the geotechnical sites with a concrete model of adjacent structure and a real subway box structure were tested by surface-wave method to investigate the influence of adjacent structures. The major influencing factors of adjacent structures on surface-wave propagation were direct distance between measurement array and adjacent structure, stiffness contrast between layers and type of seismic source.

The 2nd phase of Seoul Subway, Lines 5,6,7 and 8, is in progress. To reduce the surface traffic congestion during construction the greater part of the system has been engineered by bored tunnelling. The current tunnelling methodology is based on the New Austrian Tunnelling Method. Serveral collapses have been reported to date. Most of the collapses took place in the area forwed with soft ground. The modes and causes of the collapses were progressive failures in the unsupported surface and sliding failures due to the unfavourable joint direction. The major causes turned out to be the weakness of ground and the sudden influx of ground water from the surface. Some measures to prevent the failures are also presented. To ensure the safe tunnelling ghrough the soft ground the unsupported excavation area has to be minimized and closed as early as possible. Additional support measures such as supporting core, sealing shotcrete, forepoling, spread footing, face rock bolting and grouting should be employed as well depend on ground conditions.

지상파 DTV 방송의 직접수신 환경을 개선하기 위해서는 DTV 방송음영지역의 발생 원인과 실제 음영지역의 발생 유형을 정확히 분석할 필요가 있다. 우리나라의 DTV 직접 수신환경은 전 국토의 70%에 이르는 산악 지형과 높은 인구 밀도로 인해 고층 건물이 밀집되어 있어 전파 간섭이 발생하여 직접 수신이 어려울 가능성이 높다. 특히 DTV는 아날로그 방송에 비해 주파수 파장이 짧은 UHF 대역으로만 송출하게 되어있어 지역에 따라서는 건물이나 산 등에 의해 전파의 손실이 기존 VHF 대역보다 크게 나타난다. 이러한 전파 음영지역은 도심지의 경우 국부적으로 발생하는 것이 일반적이다. 본 논문에서는 DTV의 수신 장애가 일어나는 원인의 분석을 위해 보다 더 정밀하게 DTV 전파 환경을 조사할 수 있는 이동수신 시스템을 제안하고자 한다. 제안하는 시스템을 통해 DTV 신호를 수신하는데 있어 발생할 수 있는 다양한 형태의 전파 장애 지역을 신속하게 찾아내고 그 원인을 분석할 수 있다.
