Currently most of underground structures in domestic apartment projects are being designed for parking lot and essential parking area is growing due to the increase in car-holding number per household. Moreover, most underground parking lots of today are combined with basement, therefore a pleasant environment in underground space is strongly needed for the dwellers' use. However, there always occur high percentage of humidity and surface condensation in underground parking lot because of the nature of underground structure and they are having a bad influence on the comfort and health of dwellers. Therfore, this study is planned to compare and examine the porformance and properties of currently used construction methods to prevent condensation and finally present the most suitable method.

쇼핑몰, 백화점등이 대형화됨에 따라 사용자들을 위한 주차장도 대형화된 면적을 제공하고 있다. 따라서 시설물 관리업체는 주차 상황판 또는 안내요원을 배치하여 사용자의 주차 편이성을 제공하고 있지만 추가적인 설치 비용과 인건비가 소요되는 문제가 있다. 이 논문에서는 스마트 기기를 활용하여 사용자가 주차 공간의 현 상황을 파악하고 빈 공간을 효율적으로 검색하기 위한 주차 시스템을 설계한다.

The system proposed in this paper is a fully automated parking control system that can even protect users' information through blockchain. Unlike conventional parking control systems, the system consists of a web page that is accessible to people of all ages and ages, directly to the parking lot. Such a system would also benefit managers in the parking lot business. This is because it can reduce soaring labor costs and maximize the sales it can generate by operating 24 hours a day. In order to implement these systems, the web page was first designed using HTML and the API was configured using JAX-RS to invoke the API required by the web page. As a result, it created a web page that was easily accessible to anyone, built a server that could be accessed by more than 200 people at the same time, focused on personal information protection by encrypting the information of users through blockchain grafts, and designed a system that enabled users to complete payments easily. It is planning to add QR codes and GPS functions in the future and implement a function that allows one-touch information on parking lots and their vehicle information.

This study was conducted to analyze the relationship between the types of fiber and its content and the levels of airborne fiber concentrations at eight parking lots where sprayed insulation material was found on the walls and ceilings. Also this study was designed to find the relationship between the levels of airborne fiber concentrations and such variables as air current, humidity, total exhaust volume, surface condition of insulation material and building age. The results obtained were as follows : 1. No significant correlation was found between the levels of airborne tiber concentration and the building age, air current, humidity, total exhaust volume, space and the number of traffics. 2. A significant correlation was found between the levels of airborne fiber concentration and the MMMF content of the insulation material(r=0.7594). However, no significant correlation was found between the levels of airborne fiber concentration and total fiber content of insulation material. 3. The differences of the airborne fiber concentrations among Cateogory 1, 2 and 3 classified by the degrees of surface insulation material maintenance were very significant. 4. Two bulk samples contained 30% crodicolite and 1% anthophylite. The MMMFs, in all parking lots, included mineral wool, cellulose fiber, trace cellulose fiber, trace tiber glass and vermiculite. 5. The mean value and the range of airborne fiber concentrations at 8 parking lots were $0.0239{\pm}0.0095f/cc$ and 0.0054-0.0447 f/cc, respectively. The fiber concentrations of 35 out of 38 samples(92%) were over 0.01 f/cc which is the Environment Administration's recommended asbestos level for the underground space. This study suggests that most of building insulation materials used in Korea, contain MMMF and sometimes asbestos. Currently, MMMF pollution levels may exceed the Environment Administration's recommended level for underground space. It has been found that airborne fiber concentrations increased significantly with MMMF content and with the maintenance condition of surface material. Therefore, it is recommended that a proper management technique should be developed and immediately implemented since the conditions of surface material will be gradually deteriorated due to building age and usage. Since health hazards of the MMMF, similar to those of asbestos, are being gradually acknowledged, a proper management technique which is applicable to control total airborne fiber concentrations, both asbestos and MMMF, be developed and an acceptable indoor air standard be promulgated as early as possible.

본 연구는 대형할인점 부설주차장들의 주차수급현황을 정량적 정성적으로 분석하고, 합리적 설치기준의 재검토와 기설 주차장의 효율적 활용방안을 살펴보았다. 연구의 결과는 다음과 같다; 첫째, 모든 연구대상 할인점 주차장들은 실제 주차수요에 비해 여유가 있는 것으로 나타났다. 둘째, 할인점의 입지유형에 따라 부설주차장 이용률에 차이가 있었다. 셋째, 주차장 설치기준은 현재기준 대비 최소 20% 감축하여도 주차수급에 무리가 없을 것으로 판단되며, 할인점 입지여건에 따라 감축률에 차이를 두어야 할 것이다. 넷째, 기설 주차장의 여유 공간을 활용하기 위해 쇼핑외 목적 차량의 주차허용에 대해 적극 검토해볼 필요가 있을 것으로 파악되었다.

Accumulation of more than 20,000,000 vehicles since the establishment of the quality of life and economic development needs several parking lots and cause crack problem in Korea. Related structures in large cities due to the lack of parking garage attached to secure underground parking structures are actively being built, and the basement parking lot will continue to increase more stories and the trend is expected to be larger. But so far, construction of the underground parking structure is related to a number of problems, including cracks in the structure. Therefore, in this study, repair, reinforcement and a few non-economic losses in the current design criteria are presented. The review of the structure used to current design criteria is to minimize crack and maximize usability.

일반적으로 자가운전자들은 낯선 건물에 방문하거나 복잡한 주차장에 주차하는 경우, 간혹 본인이 주차해 놓은 차의 위치를 찾지 못하는 경우가 있다. 이를 해결하기 위해 넓은 주차공간을 가진 마트나 백화점 등에서는 최근 주차위치를 알려주는 서비스를 운영하기 시작했다. 그러나 대부분 NFC 태그를 이용하여 주차위치를 저장하거나 GPS를 이용하여 차량의 위치를 저장하는 방식을 사용한다. 이는 사용자가 직접 NFC태그를 인식시켜야 한다는 점과 GPS 수신이 어려운 실내 주차장의 경우에는 위치 수신이 어렵다는 한계가 있다. 본 논문에서는 주차장에 구역 별로 비콘을 설치하고 사용자가 주차장에 들어서면 자동으로 비콘의 푸쉬알림기능을 통해 주차위치를 알려주고 이를 저장하여 확인할 수 있는 주차위치 확인 시스템의 개발 내용에 대해 기술한다.

It is very costly to construct transportation facilities such as roads, bridges, tunnels, and public parking lots mainly because land price is very high in metropolis like Seoul. Private car oweners use these facilities more extensively than public transportation users. However, the government does not impose proper charges for using these facilities. Such improper charge causes traffic congestion and then decreases social welfare in efficiency and equity. To solve problem, many traffic demand management policies are used. Traffic management policies which are currently used or under consideration by the City Government of Seoul include the imposition of road tolls, increase of parking fees in public parking lots, increase of gasoline taxes, expanded implementation of bus only lanes, and shippujae, which requires one(1) non-driving day for 10 calendar days. This study examined the impacts of such policies on the different income classes using simulation analysis. We found that the impacts of market-oriented policies such as the imposition of road tolls and the increase of gasoline taxes is regressive. Also, we found that while the low and middle income private car users have incentive have incentive for public transportation use, the high income private car users have no incentive for public transportation use in many cases.

Numerical estimation for concentration of mono-carbon oxygen (CO) gas inside an underground parking lot with auxiliary jet fans for enhancement of ventilation is carried out by using a commercial program. Main interest lies on the diagnosis of the present ventilation system including position and selection of auxiliarly fans in addition to main suppliers and exhausts. Details of both flows and concentration of CO gas that is most important component among car exhaust gases are illustrated in this investigation and those are presented for engineering construction of an underground parking pool. Prediction data of computational work is also validated by real measurements of concentration of CO gas.
