Underground passage shopping center which is one of the underground space is a public facility. Therefore, underground passage shopping center needs physical environment that everyone (such as ordinary adults, seniors, disabled and ETC) could use it without any difficulties. The purpose of this research is to evaluate the application of universal design into main entrance space of underground passage shopping center. The scope of this research was adjusted as 8 underground passage shopping centers that are located in Seoul. Spacial scope of the research was set as public space such as main entrance space, slope way, stairway of underground passage shopping center and the content of scope of this research was the application of universal design. The conclusion of this research is as following. First, public space of underground passage shopping center needs physical environmental improvement for the convenient usage for seniors and disabled. Second, the application of universal design is needed for public space for shelter and rescue of underground passage shopping center. Third, Underground passage shopping center needs a plan to minimize the safety infringement of user by commercial activity of stores in it.

The subway station is not only an effective means to solve urban traffic problems, but also a kind of representative city shelters with a variety of functions such as urban beauty and disaster prevention. At the same time, the subway station as public facilities need activate the urban functions and through the effective design schemes for a variety of the facade of underground entrance to improve users' awareness and reliability for the subway station as a city shelters. This study is conducted to purpose the design direction considering design and disaster preventing characteristics of the underground subway station entrance. In addition, it will provide a basic reference for the subway station in the renovation and construction. The study is composed of literature reviews and field survey. The literature reviews through papers and documents related to the city shelters, the components and characteristics of city shelters, and components and characteristics of facade design of underground entrance at subway station. Before the field survey through the online surveys with evacuation capabilities and screening only the subway station. And field survey is conducted on the site with careful observation and confirmation. Last cluster analysis were applied to the finally selected samples by the SPSS Win18.0

The purpose of study was understanding necessity of environment design for underground parking lot in residential design plan and grasping design plans of 'Activity Support' that considerate women, exclude women's unsecured feeling at underground parking lot. The inquiry analyzed 6 design plan in design competition that considerate women according to precede studies, a theory of CPTED, a design guide for wayfinding, and survey. A ramp, circulation, entrance, lighting, ventilation, and space design plan are proceed on this study The result are as below. First, a rectilinear figure ramp suits entrance plan on the circulation, but if it is not possible, cross-using of rectilinear and curvilinear figure ramp plan is desirable. Second, on the circulation plan, vehicles circulation plan and equality parking distribution plan got accomplished generally, and help senses of direction because it is planed network systemize. On a large scale underground parking lot, simplify parking circulation to convenience entrance and exit for weak in sense of direction. Third, the shape and material that‘s environmentally conscious will be in use to the entrance plan. As the first stage to the underground, artwork that women prefer can modulate the rejection of underground space. Forth, natural lighting system and ventilation can make the environment-friendly space, decrease the women’s rejection to the underground, it can also keep a natural watch on the space. Fifth, on the space design plan, it can use bright and comfortable design of wall and ground to decrease the women‘s rejection, also it is useful to the sense of direction. LED indirect lighting plan that 58.7% of women prefers on survey reflects women’s state of desire that bright and atmosphere. In addition, proper use of plans that subsidiary facilities, rest area with Sunken, and nature-friendly material can minimize differences of underground and ground parking lot.

In this study, the flow field and the recirculation phenomena are investigated numerically for the model around a tunnel entrance and exit. It turns out that the air entering to the tunnel entrance comes mostly from the upper region of the entrance implying that maintaining the air clear in that region is important for the inside-tunnel ventilation. We also found that the recirculation of the exhaust gas from the exit to the entrance has a maximum effect when the flow velocity at the exit is somewhat lower than that of the entrance.

Dielectric breakdown accidents have been mainly occurred in the vicinity of service entrance section in underground power transmission systems. One cause among them is due to the excessive component value of sheath located around service entrance of cable. In this paper, as one of the alternative to prevent these accidents, the change of cross bond grounding system and the location change of IJ(Insulation Joint) are suggested. Also, to evaluate effectiveness of this changing system, circulating current and induced voltage of sheath were analyzed in steady and transient state. By comparison of the analytical results for the several possible changing systems, a grounding system and location of IJ which has the smallest sheath component values is proposed. In this paper, analysis to evaluate the proposed system is carried out by EMTP/ATPDraw. It can be used as a valuable operational material to prevent accident of the service entrance section in underground power transmission system.

The study establishes the analytical frame composed of 22 items according to the category of passageway, shop, entrance and amenity for the purpose of executing the empirical investigation of the Underground Public Pedestrian Facilities in Daegu Metropolitan City of Korea. As a result of the research work, the study finds out some problems about the facilities as follows: (1) Passageway elements - the skylight was constructed only in one place. In contrast, the standards of passageway and plaza were well-fulfilled except for one or two cases. (2) Shop elements - the cases of installing shops where they should not be located were found the most, and a case of over-establishing the shop area was found as well. (3) Entrance elements - the cases not matching roof or canopy standard over entrance facilities were found the most. Overall, the entrances and their connection to the adjacent buildings are appraised as not well-established. (4) Amenity elements - these were appraised as insufficient in all except two cases. Regarding this, not only necessary are the establishment of facilities and the effort of facility managers, but also urgent is the institutional improvement.

터널을 통과하는 운전자는 터널 외부환경과 내부환경의 차이에서 오는 변화에 많은 어려움을 가지게 된다. 특히 주간에 터널 입구부를 지나는 운전자는 터널 외부의 높은 야외휘도로 인하여 블랙홀 현상을 겪게 되며, 이는 심각한 운전자의 시인도의 감소를 가져오게 된다. 본 논문에서는 운전자가 겪는 블랙홀 현상에 대처하기 위한 방법의 하나인 카운터빔조명의 효과를 검정하기 위하여 실제와 유사한 상황을 컴퓨터에 구현하여 시뮬레이션 하였다. 터널의 조명을 설계함에 있어 특정 터널이 가지고 있는 제반 요소들을 고려한 다양한 상황에서의 운전자 시인도를 분석하고 보다 좋은 운전환경을 위한 터널조명을 만들기 위한 노력이 필요하다. 본 연구에서의 시뮬레이션에 의한 분석은 터널조명 초기 설계단계에서 비교적 단기간에 다양한 조명대안들에 대한 비교, 분석을 가능하게 하는 하나의 접근법이 될 것이다.

This paper is how to improve contaminated air by the pollutant from vehicles through ventilators and entrance at the underground station. We are looking for the environment management to take care of customers. There is two ventilation systems. One is natural ventilation system, the other is forced ventilation system. Usually, subway ventilators were installed low on the sidewalk. There are lots of craps on the ventilators, so these things interrupt influx of outside air. But the gas from the vehicles comes into the station through entrance. There is lots of noise while ventilations run. So we install the supply air vents away from the road for the customers. If it's difficult, we cover around the ventilator with clear plastic plates more than 2M heights. We also install silencer on the ventilators. We install the air curtains on the entrances to prevent dust from outside. Seoul Metropolitan has a plan to make 60M deep underground road. To improve underground road air quality, ventilators should be installed that consider the above information.

본 연구의 목적은 고속철도 터널 입구에 슬릿 커버 후드를 적용하여, 고속열차 터널 진입시 터널 출구 쪽에서 방사되는 미기압파를 저감시키는데 있다. 경부고속철도 $107m^2$의 단면적을 갖는 슬라브 궤도 0.5 km 터널에 대하여 슬릿 커버 후드라는 구조물 대책을 마련하였다. 개발시험 결과는 터널 입구에만 후드를 설치했을 경우 미기압파가 최대 41.2 %가 저감되었으며, 터널 입구에 후드를 설치하고 출구에 $45^{\circ}$ 경사갱구를 설치했을 경우는 47.7 %가 저감되었다.
