This study is to clarify the form of window and door of medieval times house which are no longer in existence, by comparative analysis between literature materials and architectural remains of united Silla and Goryo period. Particularly the window and door form change process of was analyzed, in connection with the change of term which are recorded in literature material. The form and the composition of window and door are the elements which determine the elevation design of architecture and concerned with interior environment. Therefore this study is significant in the sense that it could be used as base data for the study on the reconstruction and interior space of medieval times house. There were ho (戶) and moon (門) as door, and chang (窓) for lighting and ventilation as window. Among these, the window can be divided into fixed and openable. There were two kind of fixed window. One is called chang (窓), and it was covered by silk or paper for lighting. The other is called ham (檻), it was the form of vertical bar window and lighting and ventilation was available. And there were two kind of openable window. One is called ho (戶), which had wooden plate window leaves. And the other is called changho (窓戶), lighting was available in the condition of closing.

Korean traditionally prefer a house with a southern exposure to other styles. Moreover, pretty part of dwelling style in Korea is apartment building. But generally, there are much more north oriented rooms than opposite one in apartment. Generally, most Korean tends to consider the direction of the room as an important factor to decide the arrangement of their furniture. Also, the location of window, door, bed, and closet can affect on the decision-making process of furniture layout. So, the closet position should be determined by not only window direction and door position, but also the furniture arrangement preference of residents. After considering the window and door position, there are 16 alternatives in a room. (Multiplied 4 window directions by 4 door positions under the assumption that the window and the door cannot be on the same side of the wall.) Also, this study analyzed each room style ratio considering the symmetry of each plan by comparing the apartment building plan. This paper studied the bedroom style by analyzing the 180 apartment building plans and survey of furniture layout; the furniture in this study represents bed and desk those are mainly laid in Korean bedroom. Finally, this paper suggested the methodology to find optimal alternatives of furniture and closet layout for high-rise apartment residents, based on the door and window position, and the furniture layout preference of residents.

This paper studies the strength, fatigue sensitivity, safety factor and lifetimes by means of structural and fatigue analyses of different models of rear doors upon the opening of doors and windows leading to severe fatigue fractures of the window motor components of rear doors. The simulation models were a standard model and other models. The other models, which are denoted here as models I and II, were modified versions of the standard model, with a rib of 3mm and a thickness of 2mm as compared to the standard model. The door was modelled with CATIA V5 and analyzed with the ANSYS program. The material of the rear door was cold rolled steel (DDQ). From the study results, the standard model and model I were confirmed to be less safe upon the opening of the door as compared to the opening of a window in terms of fatigue, but model II was found to be safe for both door and window openings.

A purpose of this study was to investigate actual condition of the modern adaptation of interior elements(wall, floor, ceiling. door & window) in traditional house. The examined objects were 185 pictures of restaurants and cafe interior spaces from the 5 different monthly magazines between jan. 1993. to Dec 1997. The results of this study were as follows : 1. Mostly they were either partial adaptation from the original or partially transformed adaptation rather than entire adaptation of the original. 2. Of the traditional interior elements adapted in restaurants and cafe space only specific elements were being adapted. For example partial adaptation from the original were oiled paper flooring(Jangpan) plaster wall ceiling finish that left the rafters and beams exposed(Yondung-chonjang) and window or door frame which is vertical lattices accented with horizontal lattices grouped into three sections(Ttisal-mum) And partially transformed adaptation were oiled paper flooring rice papered (Hangji) wall Yondung-chonjang window or door frame of Wan character(Wanja-mun). 3, In regard to space the mostly adapted spaces were halls rather than rooms.

This study presents the evaluation process for door module. Its objective evades the resonance generated at module plate due to the operation of window regulator motor. For this study, the design improvement process is composed of experimental methods having three steps. First step is modal analysis at door assembly status for acquisition of dynamic characteristics which are modal frequency and damping. Second step is a vibration experiment to get the test mode considered an efficiency of window regulator motor. Last step is a vibration measurement by the form of $6{\times}6$ array on module plate. A vibration measurement of 6x6 array form can be got to three analysis results which are a transfer path of vibration using cross correlation function, a vibration map using OA level and a contribution by frequency band using coherent output power spectrum on module plate. These results are applied to SDM(structural dynamic modification) for design improvement to get around the resonance on module plate by the excitation of window regulator motor.

In Seowon architecture, there are four kinds of space conditions according to the site plan and the figure of education area. The education area has three main buildings such as Kangdang, Dongjae, Seojae. In case Kangdan locates in front of Dongjae and Seojae(so called Junkangdang-Hoojaesa), but in another case Dongjae and Seojae locates in front of Kangdang(so called Junjaesa-Hookangdang). This four space conditions affect to decide the floor plan and the window & door system of Kangdang. In Junjaesa-Hookangdang type, the front and rear wall has more open system than in Junkangdang-Hoojaesa type. In Junjaesa-Hookangdang type the direction of Kangdang is absolutely open to front education area, but in Junkangdang-Hoojaesa type the direction of Kangdang is absolutely open to rear education area. These floor plan aims at making up education area more closely. In window & door system the rear parts of Junjaesa-Hookangdang type have generally opaque system such as Golpanmoon or Panjangmoon, but Junkangdang-Hoojaesa type breaks this rule in order to emphasize front facade of building.

This study proposed how to identify window defects by using photos uploaded by occupants during the pre-handover inspection of mulch-family housing. A total of 1168 door images were acquired to generate training data and validation data. Subsequently, through the proposed algorithms, every pixel in images labeled a door was binarized using the OTSU threshold, and then dark pixels were identified as defects. Experimental results demonstrated that our computer vision-based defects identification method detects the door with a recall of 57.9%, and door defects with 63.6%. Although it is still a challenge to automatically identify building defects because of the distortion and brightness of photos, this study has the potential to support better defects management. Ultimately, the improved pre-handover inspection may lead to increased customer satisfaction.

The objective of this paper is to construct a model to be used in deciding whether to repair or rebuild school buildings is depending on their ages and other factors. The theme of this paper is the age is the main variable but other factors such as floor, innerwall, ceiling, door, inner window of the class room, outer window of the class room, inner window of the corridor, outer window of the corridor, middle window between the classroom and the corridor, light, heater, speaker, fire protection sensor, TV monitor, and telephone status would influence the final decisions. This paper employs an experimental case study method. Using the stepwise, statistical, classification method commonly used in discriminant analysis, it evaluates 12,766 rooms of 87 different high schools in Seoul. The result of this study indicates that some critical variables influencing the final decisions are the status of TV monitor, middle window between the classroom and the corridor, light, inner window of the corridor, fire protection sensor, innerwall, speaker utensil, outer window of the class room, and door of the class room. This paper also suggests a linear discriminant function will be used for this kind of studies. Finally the paper recommends policies with respect to the variables and discriminant functions evaluated.

Currently, Exterior wall's U-value about building envelope is 0.36 W/$m^2K$(Central Region), but window's one is 2.1 W/$m^2K$ according to air gap of glazing, filling gas, coating and type of windows. The door"s one is 1.6~5.5 W/$m^2{\cdot}K$ depending on material and configuration of door. As such, energy loss per unit of door is considerably larger like windows. The door for the recognition was relatively low because energy loss through the door is relatively small compared to window area. In this paper, thermal performance was analyzed through simulation targeting the door which has thermal break that can improve the insulation performance and doesn't have one. As a results of simulations, case1 was calculated as the average of 1.63 w/m2k and case 2 was calculated as the average of 4.14 w/m2k. The thermal performance of door depends on the type and condition of insulations. As a results of final simulations, Case1 was calculated as 1.06 w/m2k and Case2 was calculated as 1.27 w/m2k. As a results of the experiments, thermal performance of case 1 was measured as 1.28 w/m2k. Error between experiments and simulations is considered problems encountered when creating the samples. The effect of door frame on the overall thermal performance is slight because it's a small proportion of the door frame.
