In this study, an analytic hierarchy process (AHP) was conducted with the aim of developing a post-disaster refugee housing performance index system (PPS) to improve the post-disaster refugee housing (PRH) performance criteria for the foundation of quality-based development. The PRH was defined as a mid-term temporary housing facility that is used for a certain period before the permanent housing is established. The safety, rapidity, reusability, habitability, and economy were derived from major performance factors through prior research. A hierarchical PPS was organized by linking the major performance factors with the whole life cycle process of PRH. The priority of each performance index of PPS was determined quantitatively using the analytic hierarchy process through an expert survey. Based on AHP analysis, the performance criterion of the total weight 1-10 ranking and the performance criterion of the first rank in each category were classified into the essential performance criterion (must be achieved) and the others were classified into the recommended performance criterion (optional achieved) and the performance index was constructed considering all stages of PRH development. With the completion of the PRH performance index, it is expected that victims will be able to secure stable residence and return to their daily lives quickly.

More and more domestic skyscrapers have been rapidly constructed to get enough living space for people living in overcrowded cities. The purpose of skyscrapers is to provide citizens with useful facilities and to establish landmarks and also national and regional symbols. Previous studies have been conducted which focused on the structure, materials, plans, maintenance, and relevant information regarding skyscrapers. Skyscrapers, however, are different from other smaller buildings regarding the residential environment as well as in other ways. Recently, several problems have been raised in that the indiscreetness of current skyscrapers cannot guarantee residents a high quality living environment, and they might contain risks unless criteria are put forward to ensure that the design and facilities provide for this aim. It is judged that a set of performance criteria for the residential environment to ensurethe residents' quality of life could solve this problem. This study therefore aims to suggest a method for the improvement of the residential environment of skyscrapers by establishing residential environment evaluation factors. In conclusion, this study calculates the weight of each evaluation factor using AHP (an analytic hierarchy process) and suggests evaluating criteria. It is expected that this study could be used to propose guidelines for residents at the design and planning stage of building a skyscraper.

Recently, floor impact sound has become a serious social problem in Korea. There is an increasing need to improve floor impact sound performance using floor covering installed on the floor of apartment houses. KS F ISO 717-2 and KS F 2863 require measurement under conditions in which the resilient material is not installed. But most apartment houses in Korea install resilient materials to reduce floor imapct sound. The performance evaluation method of floor covering should provide reduced performance for use by residents of apartment houses with resilient materials. Therefore, this paper proposes a reduction performance evaluation under the conditions in which a resilient material is installed to verify the performance of floor covering.

In a typical living space, windows are directly exposed to the external noise environment. The best way to reduce outside noise is to block it from the outside, not the inside. Exterior blinds for blocking sunlight are commercialized in various ways. However, it has not yet been actively utilized in Korea. In the previous study, an experiment was conducted in an accredited laboratory to verify the sound insulation performance of an external motorized blind manufactured for shading. And it was verified that there is a sound insulation performance of 6 dBA compared to the reduction performance of a general window. In this study, we tried to confirm the reduction performance by applying the sound insulation performance of external electric blinds to windows in actual living spaces. In addition, an improvement plan was sought to increase the effective noise reduction performance. As a result of the measurement, the reduction performance of the external motorized blind itself was insufficient at the level of 1 dBA to 3 dBA. However, additional reduction performance of the 2 dBA level was confirmed by filling the gap between the blind slits.

Recently, various researches for the improvement of Han-ok performance carried out. But, most of them are tend to come from the viewpoint of suppliers rather than that of Han-ok habitants. It means that environmental elements which real habitants feel are not reflected in the design of initial Han-ok design. Therefore, it is necessary that many researchers should analyze the degree of dwelling satisfaction derived from real life. Purpose: The purpose of this study is to find the avaliable factors that need to be considered in the process of initial Han-ok design and construction through the analysis on the living performance satisfaction ratio of modern New Han-ok's habitants. Method: To achieve this goal, surveys were carried out in 83 Han-oks which actual habitants were living, located in 14 happy villages Jeonnam province. Following are survey items about residential environmental conditions; kinds of wall material, gap(connection joint between wall and wood columns) reinforcement or not, kinds of window, kinds of facilities around windows, kinds of heating source, heating types(single, multiple), financial burdens, selective heating or not and so on. Result: The results of this study may be used to improve the living performance satisfaction ratio of new Han-ok habitants and as a basis for the specifying the desired thermal comfort environment of dwelling.

This study evaluated the habitability of operators for main control room fires in nuclear power plants. Fire modeling (FDS v.6.0) was utilized for a fire safety assessment so that it could determine the performance of the smoke ventilation and operator habitability with the main control room. For this study, it categorized fire scenarios into three cases depending on the conditions in the HVAC system. As a result of fire modelling, it showed that Case 1 (with HVAC) would give rise to the worst situation associated with the absolute temperature, radiative heat flux, optical density, and smoke layer height as deliberating the habitability and smoke ventilation. On the other hand, it showed that Cases 2 (w/o HVAC) and 3 can maintain much safer situations than Case 1. In the case of temperature at 820 s, Cases 2 and 3 were up to approximately 63% greater than Case 1 in the wake of ignition. In addition, the influence of radiative heat flux of Case 1 was even larger than Cases 2 and 3. That is, the radiative heat fluxes of Cases 2 and 3 were approximately 68% higher than Case 1. Furthermore, when it comes to considering the optical density, Case 1 was approximately 93% greater than Cases 2 and 3. Accordingly, it expected that the HVAC system can influence a the performance on the smoke ventilation that can be sustainable for operator habitability. On the other hand, it revealed an inconsecutive pattern for the smoke layer height of Cases 2 and 3 because supply vents and exhaust vents were installed within the same surface.
