서울 지하철의 노선 연장, 역사 신설, 운영주체의 변화 등이 예고되는 상황에서 지하철 운영적자의 해소 또는 최소화 방안에 대한 검토가 필요하다. 운영적자와 관련하여 그간 부대사업 수입확충이 대안으로 제시되어 왔으나, 국외 사례처럼 부대사업의 범위를 도시(역세권) 개발로 확장할 수 없는 국내의 여건을 고려할 때 현실적인 대안은 역사 내부 임대시설의 효율적 활용을 통해 수입을 극대화하는 방안이 될 것이다. 이를 위해서는 지하철 역사별로 적정한 임대면적과 임대료 산정이 필요하지만, 관련 연구는 미진한 실정이다. 본 연구는 지하철 5호선과 6호선을 사례로 노선별 특성 및 입지특성을 반영한 적정 임대면적 및 임대료 산정식 도출을 목표로 하였다. 분석결과 지하철 역사 내 임대시설 면적과 임대수입은 지하철의 승 하차 인구수 또는 수입금에 큰 영향을 받았으며, 지상 상권의 영향력은 상대적으로 적은 것으로 나타났다. 특히 노선이 통과하는 지역의 아파트 매매가격의 영향이 큰 것으로 나타났다. 아파트 매매가격이 높은 지역을 통과하는 5호선은 상대적으로 가격이 낮은 6호선 대비 임대면적은 적고 적정 임대료는 높은 것으로 나타났다. 본 연구에서 제시된 산정식은 신규역사 부대시설 도입에 따른 매출액 산정 및 현재 운영 중인 부대 시설 확장방안 고려 시, 보다 현실적인 타당성 검토에 도움을 줄 수 있을 것으로 기대된다.

This study identifies visible/invisible factors and analyzes facilities, structure, and visible perceptive contents in the aspects of operation and efficiency with a focus on the interfaces between interior design of the subway and users. More specifically, it diagnoses the requirements and empirically presents improvements. In addition, this study aims to diagnose the interfaces between trains and users by reinterpreting and evaluating factors from the perspectives of users, and to elicit the universal interface and an objective form of conceptual, structural, and formative relations in regard to the conditions required to the design. As the interior design in the subway trains is for the public reflecting the value, consciousness, and behaviors of users, it should be approached through the application of the concept of universal design that considers the potential needs and psychological satisfaction of users. In arranging the indoor of the vehicles, the conditions for the facilities should be specified through the interdisciplinary approach from professional fields including ergonomics and psychology, the path of flow should be induced through the use of space and the analysis of passengers' behaviors, an integrated planning should be re-established, and continuous evaluations of basic guidelines, manuals, and requirements should be made.

In the modern society various types of transportation mode are utilized, among them the subway system is the one of the main transportation mode which more than 7.21 million people ride a day. Because of interests on the indoor air quality (IAQ) of underground public facilities, concerns on IAQ of subway system by many people are increasing. There are several approach to improve IAQ of subway station, such as installing platform screen door (PSD), frequent tunnel washing-out, and etc, however there has not been any attempt to improve IAQ of subway cabin inside. Most technologies for removing airborne particulate matters are known to be difficult to adopt on the subway cabin since the problem of maintenance cost. Therefore, the ultimate object of this study is a practical development of cabin air cleaning system which can reduce the concentration of airborne particles and harmful gases at the same time. The subway cabin air purifier (SCAP) was developed for removing particulate matters and gases pollutants inside a cabin. The whole system was designed and the roll-filter device was manufactured based on numerical prediction results. It is expected that SCAP could reduce indoor air pollutants in the subway cabin practically and it can be applied to other part of transportation vehicles.

Purpose: Subway in Seoul, Korea is an important urban mass transportation system as it carries more than 4 million people a day. To support this important mission, subway entrances were designed and installed to maximize accessibility to the stations. However, a uniform plan by the national government guided quantity and layout of the subway entrances. Therefore, the plan did not consider unique characteristics of each station area and reorganization of the subway entrance system is required to improve pedestrian environment. Method: This study grouped the subway entrances into specific patterns to propose reorganizing schemes. The authors conducted field surveys, examined case studies and proposed an entrance reorganizing plan for each type. Result: The study recommends subway entrances be installed inside adjacent building when large commercial or office complexes are nearby. The authors proposed installing a bridge connecting the stations and adjacent buildings for elevated entrances. This would be only possible when there are commercial or office facilities nearby with enough floor space. The study summarizes the pros and cons of each solution. To translate our proposals into realities, various incentives should be given to building or land owners. This study made suggestions as to which kinds of incentives exist and be effective in a range of situations.

Subway station is installed with equipment of deficient ventilation and air purification in need of routine activity for users because projectors didn't have recognition of the importance of prevention equipment on disasters in subway stations. So if the accident in Deagu is occurred again, we can't prevent it. And it is urgently necessary to improve antique subway station for the safety and service to citizens because users were increased far more. Improvement of subway station has to be modernized the backward and antique subway station and maintained and developed by the center of traffic to give the social contribution with management of social facilities. And subway station has to be made conveniently so that everyone may use the station with one-stop system including sales, business, service equipment. This study will show the improvement plan of problem in underground space and situation of metropolitan-train history to improve metropolitan-train station .we will study a traffic line and equipment relocation of underground space considering safety by choosing the improved station and problems of the underground station in seoul. And then we will study the improvement plan of air purification and sound isolation to upgrade service in citizens.

Air quality in a subway tunnel has been crucial in most of the subway environments where IAQ could be affected by many factors such as the number of passengers, the amount and types of ventilation, train operation factors and other facilities. A modeling approach has been introduced to manage the general IAQ in a subway station. Field surveys and $CO_2$ measurements were initially conducted to analyze and understand the relationship between indoor and outdoor air quality while considering internal pollution sources, such as passengers and subway trains, etc. The measurement data were then employed for the model development with other statistical information. For the model development, the algorithm of simple continuity was set up and applied to model the subway IAQ concerned, while considering the major air transport through staircases and tunnels. Monitored $CO_2$ concentration on the concourse and platform were correlated with modeling results where the correlation values for the concourse and platform were $R^2=0.96$ and $R^2=0.75$, respectively. It implies that the box modeling approach introduced in this study would be beneficial to predict and control the indoor air quality in subway environments.

The subway concrete box structure can`t establish expansion joint because of animal power delivery of the subway rail. In this case, As increase of structure volume, it is subjected to cause temperature crack. The temperature crack due to the heat of hydration classified a nonstructural crack. but it has a bad effect on durability of concrete structures. especially, in case of a subway concrete box structure, when a water-proof facilities is beaked on an outer-wall, the water leakage occurs through a penetration crack generated from a wall of the concrete structure too. This paper, for the subway concrete box structure, examined a condition of temperature crack occurrence by a heat of hydration concerned external temperature from analysing by a three dimensional finite element method.
