The most principal approach to improve indoor air quality(IAQ) of subway was to examine the fine particulate(PM-10) from the emission sources. Therefore, this study was carried on the investigation the fine particulate for comparison with the removal efficiency of PM-10 in divided the PSD(Platform Screen Door) and Non-PSD subway station from July, 2007 to May 2008. In the monitoring results, the range of PM-10 concentration of Non-PSD station was $44.6{\sim}116.5{\mu}g/m^3$ and the range of PM-10 concentration of PSD station was $23.9{\sim}81.1{\mu}g/m^3$. And then the range of PM-2.5 concentration of Non-PSD station was $17.4-56.6{\mu}g/m^3$, and then the range of PM-2.5 concentration of PSD station was $17.9{\sim}34.4{\mu}g/m^3$. In comparison with the results of the PSD and Non-PSD subway station, we found that the PM-10 removal efficiency of PSD was 30-40%. In conclusion, the PSD will be applied the effective facilities of decreasing PM-10 in subway station in Korea.

To prevent safety accidents such as injury or death from falling by blocking platforms from trains, the Seoul Metropolitan Subway Corp. have gradually installed screen doors in platforms of 115 subway stations in Seoul on lines 1, 2, 3, and 4. Installation in nine areas among those has been completed and screen doors are being operated as a model operation. Traffic signs should be clear for users. The essential functions of signs should be fully investigated from the aspect of user as well as the visual beauty and recognition. Signs should be able to provide users with information regarding location, position, directions, etc. Particularly, safety and convenient signs should be visually and sensually correlated. However, the entire screen doors in platforms installed in line 2 subway in Seoul are used for commercial advertisement, consequently, the functions and roles as public signs are not fulfilled aggravating inconvenience for users. In this study, cases have been studied to investigate requirements for user-oriented sign system in platform and public sign space to fulfill the functions of sign system in platform. Using an anthropometry approach, the study aimed to obtain the space to install the sign system and to systemize necessary and sufficient conditions for user-oriented system for platform in which screen doors have been installed using. The study suggests fundamental information to obtain the space of public sign system on the entire screen door.

본 연구에서는 열차와 지하철 역사 형상긴의 유통 흐름에 대한 상호작용을 고려하여 승강장 스크린도어(PSD)봐 비정상 풍압해석을 수행하였다. PSD의 주목적은 열차가 역사 안으로 진입할 때, 인명사고를 예방하고 풍압, 오염된 분진, 소음 등을 차단하는데 있다. PSD에 대한 비정상 풍압수준을 정확하게 예측하기 위하여 이동격자법을 활용한 전산유체역학 기법이 적용되었다. 개방형 및 밀폐형 역사가 고려되었으며, 열차가 역사를 통과하는 경우와 역사에서 멈추는 경우에 대한 풍압 수준을 상호 비교하였다.

PSD(platform screen door) was completely installed at all of Seoul subway station(line 1~8) using 640million people per day by 2010. After installation of PSD, the influence of train induced wind at platform decreased, but is estimated to increase in subway tunnel. In this paper, train induced wind occurred by pass of subway at platform was measured and analyzed using numerical analysis by computational fluid dynamics.

Platform screen dorr (PSD) is equipment composed of screens and doors on the platform of subways or light trains, separating the platform from the railroad. The equipment is opened and closed in connection to the doors of carriages. In order to operate the system safely, it is important to understand the characteristics of key parts. There are many parts and environmental factors such as voltage, current and temperature change but the present study measured the change rate of torque and energy changes according to the temperature of the driving motor and analyzed the characteristics of the changes and examined the features of a motor required for stable PDS and the conformability of control programs.

본 논문은 지하철 PSD(Platform Screen Door)광고의 효과증진을 위하여, 동적 대상은 정적 대상에 비해 강한 시선 유인 효과를 가진다는 이론적 배경을 전제로, 동적 이미지를 활용한 새로운 형태의 PSD광고를 제안하는 것에 연구의 목적이 있다. 이를 위해 스크린도어와 전동차의 관계 분석을 통해, 효율적인 동적 이미지 구현을 위한, 위치적, 시각적 요소들을 도출하였다. 그 후, 이러한 요소들을 적용한 예시광고를 제작, 3D 프로그램 상에 적용함으로서, 동적 PSD광고의 구현 과정을 확인하였다. 연구결과, 시간차를 이용한 이미지 합성을 통해서 동적 시각효과를 보여줄 수 있는 새로운 형태의 PSD광고 제작이 가능함을 확인할 수 있었고, 이미지들의 조합과 적용에 따라 다양한 시각적 표현이 가능하기에, 본 연구의 제안이 PSD광고라는 광고매체에 다양성을 부여할 수 있음을 또한 확인하였다.

In the present study, the analysis on heat and fluid flow in subway station platform is carried out by considering the pressure drop between screen doors and stair passages. To investigate the effect on the characteristics of heat and fluid flow of pressure drop, Numerical simulation is applied. The present results show a better cooling condition, in the case of without pressure drop.

Subway platform is divided into Side-platform type and Center-platform type. In this study does quantitative fire risk assesment of subway platform types in numerical analysis by using CFD model. From the result of this study, 1) All exhaust mode was low-end result it seems most fire risk at Side-platform station. 2) All exhaust mode was low-end result it seems most fire risk at Center-Platform station. 3) When comparing same type exhaust mode of Side-platform and Center-platform that last thing was visible $9.1{\sim}72.34%$ low-end fire risk. Center-platform is more opera-tive than Side-platform that reduce fire risk when that was same dimension and external environment. Designer look upon a fire characteristic of subway platform types when he make smoke control air volume and platform area design.
