Urban freight system includes not just intra-urban freight movement but also inter-urban movement as well. Hence, to make Busan a hub of North-east asia freight movement it is necessary to develop a comprehensive plan for infrastructure expansion as well as improvement of freight system based on the present facility situation. This study identifies the status of freight facilities in Busan by establishing the freight related infrastructure Database(DB) utilizing Geographic Information System(GIS), and to enable planners and decision-makers to utilize the DB to develop a future plan. The DB includes port facilities, major and minor arterial roads, railroad lines and facilities, depots, center city business areas, and urban infrastructures which are related to the freight movements. The analyses show that major transportation facilities in Busan consist of roads, railroads, coastal transportation, and international transportation, and it was found that intermodal facilities are inadequate for freight system in Busan. The results of this study will be useful for freight experts and planners to develop a comprehensive freight system plan.

The purpose of this paper is to evaluate the noise level and source, reduce the subway line II noise. As a result of measurement of subway line II in Busan the highest value section of uproad line was from Jigegol to Motgol by 89 dB(A). The sections of conversation and listening interference(over 80 dB(A)) were 21 sections(55%) of 38 sections. Among these sections, 15 sections(71%) were produced rolling noise, 3 sections(14%) squeal noise, 2 sections(10%) braking noise and 1 section(5%) fan noise, and then a main noise source was the rolling noise. In case of downroad line, the highest value section was from Busan Metro Art Museum to Centum city, Motgol to Jigegol by 88 dB(A). The sections of conversation and listening interference(over 80 dB(A)) were 18 sections(47%) of 38 sections. Among these sections, 15 sections(83%) produced rolling noise, 2 sections(11%) squeal noise and 1 section(6%) braking noise were investigated in this study. and then a main noise source was the rolling noise.

지하구에는 국 가의 신경이라 할 수 있 는 전력, 통신, 상수도 등 주요시설물들이 수용되어 있으며, 지 하구는 화재, 집중호우에 의한 침수, 외부침입 등의 재난에 항상노출되어 있다. 2006년 12월에 발생된 구리 전력구 화재와 2000년 여의도 공동구 화재 등에서 보듯이 화재가 발생하면 화염과 연기, 유독가스로 인해 내부로 진입할 수 없으므로 조기경보 및 조기 대처가 매우 중요하다. 따라서 본 논문에서는 지하구 중에서 통신케이블을 수용하는 통신구의 재난에 조기 대처할 수 있는 통신구 원격감시 시스템에 대해 기술하고자 한다. 통신구 원격감시 시스템은 통신구내의 침입, 침수, 화재 등을 모니터링하여 재난을 미연에 방지할 수 있도록 하고, 각 감지기 및 장치에 설정된 임계치를 초과한 경우 경보 현황을 운용자에게 알려 신속하게 조치할 수 있도록 하였으며, 시스템의 안정성과 확장성, 유지보수의 용이성 등을 고려하여 통합/분산 서버, 데이터 수집장치, 감지기 등 으로 구성 하였고, 시스템간의 연동과 호환성을 위해 표준화된 통신 프로토콜을 사용하였으며, 필요에 따라 감지기 및 장치를 수정, 추가할 수 있도록 개발하였다. 그리고 이를 검증하기 위해 부산지역의 지하철병행통신구 3.8km에 대해 시범설치하여 운용함으로써 시스템의 안정성, 운용성 등에 대해 검증하였다.

In this paper, the comparison on the fire driven smoke flow for platform types was conducted in the Deeply Underground Subway Station. Soongsil-University station (47m depth) as a bank type platform and Mandeok Station as a island type platform were selected for fire numerical simulation. The characteristics of fire driven smoke-flows were analyzed from the simulation results. The proper plan of evacuation against fire for each type was considered through the results.

In the new Seoul-Busan high speed railroad construction specially city center passage roadbed establishment is recommended the staibility for the existing subway tunnel segments of Busan subway line No. 1 and No.2. regarding the appearance condition, a quality condition and the durability of the objective facility site exact inspection, and it evaluates the numerical analysis which uses MIDAS GTS it leads and there is the objective of the place where the stability of the objective facility and this tunnel it investigates. To immediacy of the on-the-spot inspection result whole facility it is a condition where the reinforcement which is simple not to be hindrance is necessary, 2nd Line case it is a condition which transfer is good but the general defect and the damage which occur from the tunnel of NATM type were confirmed part. While roadbed establishment constructing that the continuous maintenance is necessary, it is judged. The result of 1st, 2nd Line maximum sinkage, unequal sinkage and the lining stress of numerical analysis are within permission and the damage degree is appearing with the fact that the degree it will can disregard it is slight. But it enforces necessary Pre-grouting in order to minimize an actual tunnel face conduct and when the tunnel is excavated it is judged with the fact that necessary to minimize the outflow possibility.

In spite of drastic development of underground technology too many uncertainties still exist in design and construction of underground structures. Estimation of ground parameters might be one of those uncertainties in design of underground structures. It is not an easy task to estimate the parameters reasonably well in advance in the design stage. The main purpose of this paper is the best parameter estimation in the underground structures. In order to estimate unknown model parameters from the in-eitu measurements as well as prior estimates, the Extended Bayesian Method(EBM) is utilized and implemented with Finite Element Program. The parameter estimation model utilized in this study is applied to two underground structures : the one Pusan subway tunnel: and the other Darlington intake tunnel in Canada, and the effectiveness of the proposed model is illustrated.

These days, the value of the limited land rises in the city according to the increase of the population and the industrial development. And various studies on estimating the land price have been accomplished for the purpose of using the land efficiently. As a result, the officially assessed land price system was arranged. However the system is insufficient to reflect realities. Therefore, in this study, we examined the spatial distribution of the land price by joining spatially the officially assessed land price of Haeundae-gu, Busan from 2004 to 2008 to the map of lot number. We also computed and compared the change rate of the land price for 5 years. And we analyzed the relation between factors including the distance from the subway station, the land use and the land category which have an effect on the officially assessed land price and it using GIS technology.

Currently, domestic architecture has applied the building fire-fighting equipments to most buildings except conventional houses, villas and facilities, and so on. However, the use of fire-fighting equipments what are not working properly result in a human life and property damages consistently like a fire of Icheon warehouse facilities, Korea cold storage, the tragic incident of subway in Daegu and the recent issue of a fire in the high-rise efficiency apartment, etc. In this study, I'm trying to seek solutions by taking research on the actual condition of fire alarming system, fire escaping equipment, Indoor Fire Hydrant Installation.

When an underground pipeline runs parallel with subway DC electrification system, it suffers from stray current corrosion caused by the stray current from the rails negative returns. Perforation due to the stray current corrosion may bring about disastrous accidents such even in cathodically protected systems. Traditionally, bonding methods such as direct drainage, polarized drainage and forced drainage have been used in order to mitigate the damage on pipelines. In particular, the forced drainage method is widely adopted in Busan. In this paper, we report the real-time measurement data of the pipe-to-soil potential variation in the presence and absence of the IR compensation. The drainage current variation was also measured using the Stray Current Logger developed. By analyzing them, the problems of current countermeasures for stray current corrosion are discussed.
