With advantages of open spaces and existing HVAC facilities, subway station, if unexpected disastrous situation happens on the ground, can be used as a temporary safe place for evacuees. The main objective of this study is to establish a guideline on estimating evacuation capacity of the subway station and evaluating levels of service of evacuation for officials to control the situation. This guideline includes available spaces of the station, capacity of sanitary fixtures, and total number of passengers, etc. In this paper, we first analyzed the number of passengers of SMRT (Line 5~Line 8) during AM peak hour and then evaluated the number of passengers using toilets at that time. In addition, we calculated the seating capacity of subway stations on SMRT using the difference between the actual number of toilets and the estimated number of ones from the occupancy time of each toilet.

This study investigated the ratios of area, according to the domains and functions, of a public library. To this end, 20 public libraries were selected as samples from the 2012 Public Library Construction Casebook and from cases of consulting on the construction and operation of public libraries. The domains of a public library were categorized into data reading, cultural education, operation, common use, and others. There was a large difference in the area ratios between public libraries that were built with the aid of consulting (Group B) and those without consulting (Group A). In functional terms, the data(bookshelf) space and reading space had similar ratios within a data reading room, while the ratio of the library information space was smaller. Within a general data reading room, the ratio of the library information space was 12%, while the ratios of the data space and seating space were 44%, respectively. Moreover, within a data reading room for children, the ratios of the library information space and children's space were adjusted to 14%, respectively, while the data space and seating space each accounted for 36%, with either 3- or 5-decker bookshelves installed. This study has identified how to calculate the area for each domain, capacity of books, and seating capacity by applying area ratios through functions in the data storage domain, along with numbers of books and seats per unit space. This study has also succeeded in calculating the required area and seats for each type of data storage room by applying the number of books that exist. However, this study has its limitation in that the regional characteristics(Metropolis, Small & medium size cities, Rural areas) were not considered because the number of samples was only 20 libraries.

This study investigated residents' preferences for spatial features of sitting areas in assisted living facilities, and provides recommendations for planning sitting areas to support residents' spatial preferences and social interaction. The study participants were 69 residents of eight assisted living facilities (30+ resident capacity), located in south central Texas. A photographic comparison method was used, in which residents were shown 20 matched pairs of photos, with a single feature digitally modified in each pair, and asked to select which environmental representation they preferred. The hypothesized spatial characteristics were identified in practice based literature as those that may encourage usage of sitting areas: viewability, variety, homelikeness, and privacy. Most of the hypothesized features were preferred by participants, with the highest preference found for non-institutional furniture arrangements and naturalness, followed by increasing enclosure and variety of seating. Preference was less significant for domestic cues such as carpeted floors, divided light windows, and boundaries defined by different colored material or columns, possibly due to their physical impairments or preference for visual openness. Participants' level of mobility assistance was significantly related to their preference for some features, such as seating with people-watching capability, and carpeted floors. The findings have implications for facility architects and administrators engaged in resident-oriented spatial planning.

유선 및 도선 중 선박길이 12미터 미만인 소형선박은 선박안전법에 따른 복원성 기준 적용이 면제되며, 유선 및 도선 사업법에 따라 승객 및 선원이 탑승 가능한 면적을 고려하여 승선정원을 정하고 있다. 이러한 유선 및 도선 중에서는 건조 이후 차양의 설치 등 복원성에 영향을 미치는 상부 구조물을 설치하는 사례도 적지 않다. 이에 본 연구에서는 상부 구조물을 설치한 도선에서 실제 발생한 전복사고의 사례를 바탕으로 해당 도선의 복원성을 추정하여 사고 원인을 분석하고자 하였다. 분석 결과, 승선정원을 초과한 상태에서 승객들이 동시에 하선하고자 기립하여 복원성이 악화된 것으로 나타났으나, 해당 도선이 승선정원을 준수하더라도 한쪽 현의 승객들이 기립하면 횡경사에 의한 전복의 가능성이 존재하였다. 따라서, 보다 안전한 유선 및 도선사업을 위하여 선박길이 12미터 미만의 유선 및 도선에 대하여 건조 및 개조 시 실선 복원성 시험에 의한 승선정원 산출, 승선정원의 총중량 한곗값 제시 등을 개선방안으로 제시하였다.

A prestressed/precast concrete system was used to build the new Asian Olympic Stadium Project in Pusan, Korea. The stadium(mainly intended for cycle racing) is designed for the 2002 Asian Olympic Games and has a seating capacity of 20,000 spectators plus a few private suites. More than 1300 prestressed/precast components were used and they include single columns, primary beams, cantilever beams, double riser stands, and double tees. Especially, a total of 24 cantilever beams is used on the fourth story for the stands and double tees. These 8m long beams are post-tensioned to prevent cracking, to increase their durability and to serve serviceability by vibration. A cantilever section with cast-in-place topping is 800mm wide and 1500mm deep. Cantilever beams are connected to the column with the corbel by cast-in place concrete. Bonded post-tensioning tendons were assembled at the job site. Dead-end anchorages were installed in the end of cantilever beams and live-end anchorage is the opposite of them. This article presents the geometric layouts, design features and so on.

This paper presents the contact thermal behaviors of mechanical seals depending on the contacting face geometry. Using the finite element analysis, the temperature distribution, thermal distortion and leakage have been analyzed as functions of sealing gap and rotating speed of the seal ring shaft. The FE results indicate that the inclined contacting face may be more effective and stable based on the results of thermal characteristic analysis if the seal ring has been designed with a same thermal capacity between conventional rectangular sealing faces and inclined seating surface of seal rings.

This research aims to establish the size standard of university library's user space, and present the standard and method to calculate total area required in the planning of new building construction and remodeling. Nine university libraries newly constructed or remodeled since 2000 were selected among the libraries of large scale universities with more than 10,000 enrolled students as the target libraries in this research. The target libraries were classified into A group (five cases partially remodeled) and B group (four cases newly constructed or fully remodeled) on the basis of the change of times. A university library can be divided into three spaces (user space, administration space and public space). This research classified the reading room in the user space into bookshelf zone, reading zone, information/office zone and hall/other zone, and analyzed area ratio according to each zone. B group's bookshelf zone decreased 12% more than A group, and B group's reading zone increased 10% more than A group. However, there was no big change in the area ratio of information/office zone and hall/other zone. This can be interpreted that university library changes from book and archive preservation-oriented space to user-oriented space. This research presented a proper reading room area calculation method, based on the capacity of books, by reflecting such a change. Each zone's standard was set up through classification of domestic and international standards, based on which, the calculation method of university library's total floor area required was presented. The reason why there was difference in university library's total floor area required according to domestic standard and international standard was that the number of enrolled students per seat in the reading room was different. The area calculation methods presented in this research can be utilized as useful data upon planning university library construction or remodeling.

As the seniors and the disabled has increased, the demand for cultural centers has also increased in many local areas. This means that the local cultural centers designed from the viewpoint of universal design are needed, so that to be used by everyone without any difficulties. This study examined the applicability of universal design principles to the public service areas of the local cultural centers. The subject cultural centers were three local ones which had seating capacity of more than 1,000 and opened after the year of 2,000 in Gyungnam. The spatial scopes of the study were six public service areas of the local cultural centers : entrance area, corridor and pathway, stair, ramp, elevator, and rest room. The total 65 items for evaluating the applicability of universal design were selected and examined for six areas. On the whole, accessibility, such as wide pathway and flat floor was good. However, the following improvements were needed. 1) Handrails and rounded corner were needed on walls. 2) Consideration of the visually impaired like as braille sign was needed. 3) The handrails on ramp should be installed for usability. 4) The automatic door would be more useful to the physically disabled users. 5) Wider space and familiar handrail design and color were needed in the rest rooms for the handicapped.

한국 영화의 시장 점유율은 최저 2008년 42.1%에서 최고 2013년 59.7%로 높은 점유율을 유지하고 있다. 그러나 멀티플렉스와 와이드 릴리스 전략, 4대 메이저 배급 회사와 3대 멀티플렉스 체인의 독과점의 영향으로 한국 영화 흥행의 양극화 현상은 심화되고 있다. 한국 영화 흥행 집중도는 2004년 0.53에서 2014년 0.85로 심화되었다. 흥행 순위 상위 10%의 한국 영화가 차지하는 관객 수 비중은 2004년 30.28%에서 2014년 71.2%로 급격히 높아진 반면에, 흥행 순위 하위 50%는 2004년 11.03%에서 2014년 0.08%로 아주 낮아졌다. 상영 스크린 집중도도 2004년 0.36에서 2014년 0.67로 심화되었고, 상영 횟수 집중도도 2004년 0.46에서 2014년 0.78로 높아졌다. 좌석 수의 집중도도 2004년 0.50에서 2014년 0.79이다. 많은 관객이 선택하는 영화라서 상영 스크린 수를 늘리고, 상영 횟수를 늘리고, 많은 좌석 수를 확보한다면, 이는 자연스러운 시장의 선택 결과라고 하겠다. 하지만 이들 영화들의 좌석 점유율 집중도를 보면 그렇지 않음을 알 수 있다. 좌석 점유율 집중도는 2004년 0.22에서 2014년 0.38로 다른 집중도와는 달리 완만한 증가세를 유지하고 있다. 상위 10% 영화들의 좌석 점유율은 2004년 38.2%에서 2014년 32.3%이며, 하위 50%는 2004년 23.5%에서 2014년 23.8%로 나타났다.
