In order to account for a price variation of apartment that places near a newly constructed subway station, a spatial hedonic model was developed to examine spacial characteristics that affect a purchasing price of an apartment using a White Estimator. In particular, the paper aims to examine various effects of subway 7 construction on an apartment price in Seoul Metropolitan Area. As explanatory variables, an apartment size, distance to a closest subway station, distance to the Central Business District (CBD) of Seoul, the number of years after building, and a lagged variable of the apartment purchasing price were used. The lagged variable plays a role of representing a spatial weighted average of previous prices of other apartments that locate within 3 km from the apartment. For a precise study, an entire sample was divided into two sets, southern area and southwestern area of Seoul, and two different spatial hedonic models were estimated. Not only before and after analysis, but also with and without analysis were conducted to compare with different effects of the spatial characteristics of two areas. The results show that before the construction of the subway 7, the prices of the apartments in the southern area were more sensitive to the apartment size, the distance to a closest subway station, the distance to the CBD, and the prices of the other apartments locating within 3km rather than those in the southwestern area. After the construction, on contrast, it is found that the apartment purchasing prices in the southwestern area are more sensitive than those in the southern area due to people's expectation regarding a new development around the subway station. In addition, the prices of the apartments locating closely with a transfer station are more likely to go up by increase in the apartment size, the distance to the station, and the prices of the other apartments within 3 km. Compared with the negative effects of the distance to the station on the prices in the other models, the positive effect of the distance to the transfer station might be caused by the characteristics of commercial area in which people are not likely to live.

서울시 지하철은 1974년 개통되어 네트워크를 지속적으로 확대해왔다. 지하철은 최근 전체 여객 통행의 40% 정도를 담당하며 가장 자주 사용되는 교통수단으로 자리매김하였다. 따라서 지하철 접근성이 시민들의 일상생활에 미치는 영향이 매우 크다고 볼 수 있다. 하지만 지하철을 비롯한 대중교통 자원은 공간적으로 균등하게 분배되지 않아 이로 인한 혜택이 불균등하게 배분되는 경우가 일반적이다. 본 연구에서는 서울시 지하철 접근성의 공간적 분포와 형평성을 살피고자 한다. 지하철 접근성은 역 간 이동시간을 계산하여 산출하였고 형평성은 지니계수를 적용하여 수치화하였다. 그 결과 지하철 접근성은 중심부-주변부 패턴을 보이며 중심업무지구는 높게 서울시 외곽은 낮게 나타났다. 또한 지하철 네트워크는 인구 및 대중교통 의존 계층의 공간 분포보다 고용자 분포를 고려해 보았을 때 보다 공평하게 배분되어 있음을 확인하였다.

Many people transfer from the automobile to the subway because of increasing in oil price and improvement of mass transit system of Seoul Metropolitan City. But Seoul Metropolitan Subway have brought out passengers discomfort because it is more crowded over the appropriateness because of very high utilization though it is highly technically facilitated. This study deals with the development and simulation study of subway train simulator. We performed the validity simulation study for the simulator for the interval from Sindorim station to Samsung station in Seoul Subway Line 2. We analyzed the simulation results considering crowdedness after we defined the concept of crowdedness. Also we accomplished the analysis of simulation results after simulation under the assumption that the crowdedness is alleviated by controlling the passengers using RFID technology.

A self-administrated non-malignant respiratory symptoms questionnaire was sent to 1,099 citizens who take subway running in Seoul city. Symptom prevalence rate was high: 70.6% of subjects reported 'chest tightness', 43.4%, 'dysphnea'; 76.2%, 'dry cough'; 49.5%, 'runny nose'; 94.4%, 'drowsiness' when they take subway. The groups responding significant higher respiratory and drowsiness symptoms were 'young passengers' (vs elderly passengers), 'the female' (vs male), 'using subway everyday' (vs often), 'using subway for rush-hour time' (vs other than rush-hour), 'using transfer subway' (no transfer), 'using underground track' (vs ground track). Logistic. regression model was employed to find personal and subway characteristics affecting non-malignant respiratory symptoms. This study concluded that respiratory diseases history such as asthma, rhinitis, sinusitis, hypersensitivity pneumonitis significantly affect 'dry cough' and 'runny nose'. Thus, passengers with respiratory diseases history shows 2.8 times greater 'dry cough' than and 3.4 times greater 'runny nose' than those passengers without respiratory diseases history felt. This results indicated that several measures have to take to protect sensitive groups such as passengers with respiratory diseases, children and elderly people. Also passenger who use to transfer shows 1.7 times higher runny nose symptoms than that passenger who do not transfer felt.

The Seoul subway line No.2 is the one of the busiest metro service line of the passenger transportation in Seoul metropolitan city. The number of the passengers served by the Seoul subway line No.2 is more than 1.9 million in a day according to the transportation reference of 2004, which is about $15\%$ of the whole population in Seoul metropolitan city. This is the reason why the Seoul Metropolitan Subway Corporation(SMSC) is implementing the refurbishment of the current ATS signalling system of Seoul Line No.2 into the most advanced ATO system with the continuous air-gap telegram transmission through the track circuit without any suspension of the train service either in when or in where, which is the first in the world in its attempt to refurbish the old signalling system under service without any suspension of the train operation.

As people are getting interested in themselves ever than before, the value of culture industry which can satisfy their emotions has been considered much more important. According to this, in terms of the 'space', it is better to represent 'space' not just as a functional space, but the human-centered and making human and nature together. In this society, the most human-centered design can be achieved by pursuing value which is friendlier to nature. And it is sure that the interior design that completes life quality as well as emotions of human will be common in near future. There already has been a try 'Green interior' in subway station in variety ways, and now it is needed to make indoor display in Seoul subway station different in order to satisfy human emotions. If culture space in Seoul subway station applied eco-element interacts with indoor environment, it is surely expected that people have better feeling on subway station as well as help eliminate negative elements which underground have had. In culture space, there are many advantages for displaying space into 'nature', that is, natural space represents the best comfortable and agreeable space, and future-oriented design when it gets interacted with environment. Application of 'Green interior' in Seoul subway station makes special place ness by its symbol and image, so that it derives people to have more natural and comfortable movement distance in subway station, offers more comfortable and cozy place as well. Furthermore, it makes people very moved by experiencing the most special culture space that they have ever had.

Network approach is used to find the shortest paths and transportation time between the subway stations in Seoul, Korea. Because of transfer stations, we reconstruct the subway network to compute the shortest routes and corresponding transportation times. The reconstructed network is useful to obtain desired information because it can handle the transfer time between tracks. Time and route information about the subway system is obtained and it will be displayed in the subway guide board at each station. Then, all passengers can have the information of shortest route to a destination and corresponding transportation time.

Accurate subway demand estimation which is essential for better route selection can be achieved by the exact definition of the influence sphere of subway station. The influence was derived implicitly from the analysis of access time to the station for the cases of Seoul. Access time distribution was investigated by trip purposes, by age, by income, by sex, by travel distance, by kinds of thickets, by the location of station for the analysis of relationship between access time and socio-economic characteristics or urban structure. The difference of average access time between direct access trip and transfer trip which is found 8.6 minutes and 6.1 minutes respectively also investigated. The small difference implies poor transfer system of Seoul subway. 83.1% of subway users are coming from the distance of 10minutes' walk and average access time is 7.8minutes as a whole.
