Using the artificial sun, namely the BIOSUN, we can control the sun light according to the latitude and longitude and for the seasonal changes and apply that to subway stations. By doing this, we can expect three effects, a. allowing the plants to grow inside the stations which will in turn contribute to improving air purity, controlling humidity, and reducing dust for pleasant environment, b. pleasant environment will foster positive emotional responses of the passengers and that would increase the satisfaction, and c. fostering good service for the citizenry and establishing an environmental friendly image of the Seoul Metro Subway System. The purpose of this thesis paper is to contemplate on the uses of the artificial sun powered by the microprocessor of a Light Emitting Diode (LED) in controlling the light and how the light can be utilized in facilitating photosynthesis that would allow plants to grow inside subway stations.

Talk-Back systems comprised of master-equipment at the control room and slave-equipment at turnouts refer to the intercommunication facilities that optimize mutual communication between maintenance staff on trackside and the control room to facilitate quickness and accuracy of train operation control and its maintenance within depot and on mainlines with turnouts for direction switching of the trains in operation. The weakness lies in additional maintenance costs of cables since the Talk-Back system installed on line 1 along with line 2-4 has a profound effect on the voice quality leading to the attenuation and crosstalk of the system due to the deterioration of cables and environmental factors. This paper discusses the Talk-Back system in a radio communication environment with the application of RF(Radio Frequency) communication system from the wire communication system by cables to ameliorate these problems, and deals with the energy saving environmentally friendly facilities in consideration of replacing power section at salve-equipment with solar batteries benefitting the system in light of energyconsumption.

Urban railway system that leads the urban public transportation enables the passengers to use the subway system safely and conveniently by indicating the destination of, status of approach of and other information on train through Train Destination Equipment(TDE), which is one of the important passenger services. The existing system is composed of Host Station Equipment(HSE) and operator panel that receives necessary input on train information from Total Traffic Control System(TTC), Local Station Equipment(LSE) that controls Train Destination Indicator(TDI) installed at each station, and Train Destination Indicator that ultimately displays train information to the passengers using the train system. This study aims to realize stabilized and reliable announcement system for destination of train by considering processing procedure and method of expression of inputted information of the existing system of notification of announcement of destination of train that can be applied in the RFID, which is the base technology of USN for which service expansion is easy, and to realize system that considers interface with USN and expandability with other facilities in the future.

스마트폰의 대중화와 노트북, 태블릿과 같은 각종 무선기기의 사용이 활성화 되면서 일반 무선 인터넷 사용환경을 위한 인프라 구축은 폭발적인 증가세를 보이고 있다. 이에 반해 공공기관의 무선망은 정부의 전략적 정보화 사업의 추진에도 불구하고 철저한 보안성 검토가 선행되어야 하는 제약으로 인해 유선망에 비해 그 도입이 늦어지고 있다. 무선망 인프라 구축은 업무 효율을 높이고 시설 구축ㆍ운영 비용의 절감 등 유선망에 비교하여 많은 장점을 가지고 있으며, 일반 업무와 더불어 통합 센서 네트워크(USN), 근거리통신망(NFC), 클라우드 서비스 등 특수한 각종 모바일 서비스 환경을 위한 도입 필요성을 고려하여, 도시철도 기관의 무선망 구축에 따른 보안대책을 검토하고 대안을 모색해 보고자 하며, 터널과 같은 지하공간의 특수성, 이동중인 전동차 내에서의 무선망 연동문제 등 각종 환경적 요인을 분석하여 도시철도 Wireless Office 구축 가이드 라인의 모델을 제시하고자 한다. The popularization of smartphones and laptops , tablets and other wireless devices such as the use of the active environment for general wireless Internet access infrastructure has shown the explosive growth . On the other hand, the wireless network of public institutions of government , despite the promotion of strategic business information and thorough security review to be preceded by the introduction of constraints compared to the fixed-line network and is delayed . Wireless network infrastructure to improve the operational efficiency of the facility construction and operating costs savings compared to wired networks has many advantages , and general business , with Ubiquitous sensor network (USN), Near Field Communication(NFC), Cloud services, special various mobile the need to introduce a service environment , taking into account the urban railway building wireless networks, according to the agency"s review of the security measures and want to explore alternatives , and the specificity of the underground tunnels , such as , wireless networks are moving train in the linked issues of by analyzing various environmental factors Wireless Office building urban rail is to propose a model of the guidelines .
