The purpose of this study is to analyze physical characteristics, spatial composition, and using behavior of lounges in elderly skilled nursing facilities as spaces for activity programs and also to evaluate the spaces with the framework based on the indices for performing activity programs in elderly facilities. The results of the study were as follows: First, the lounge of an independent type ensured the privacy to perform programs, and so activities were managed more systematically. On the other hand, an expanded corridor type made the elderly feel difficult to pay attention to activities due to co-use of lounges and corridors. In a lounge of a hall type, the elderly had easy access to the place, but it also had weak home-like atmosphere because the space was used as a lobby entrance. Second, the facilities with western types of tables in whole lounges showed big changes in spatial composition, such as moving all the tables for any activities. It resulted in more preparation time and created obstacles in passages and space use. Third, in the evaluation of lounges based on the framework, most of lounges had accessibility of good quality, but they needed to improve home-like atmosphere and flexibility. To create home-like atmosphere, various spatial compositions and classifications in the lounge should be tried. Moreover, enough space and easy movable furniture can be considered for flexible spatial compositions.

This study was carried out to focus on the user-oriented design of patients' room in general hospital. The purpose of the study was to examine the users' evaluation on their patients' rooms in H General Hospital and to suggest how to improve the patients' room design. The users were inpatients, care givers, and nurses, 300 subjects of each 100 users in H hospital. They evaluated 26 items related to the patients' room design using by 5-points Likert scale. Also, they answered three elements which bothered them, what needed improvement, and what they feel ill at ease. The results were as followings; 1) The users evaluated positively the location and size of window. This implies that the current one is relatively ideal and deserve to be maintained. 2) The users responded negatively to the thermostat system and the space for care-givers. 3) The lack of space for care-givers and visitors, common use of refrigerator and bathroom, and the lack of space bothered the users. 4) Most users mentioned the lack of space in patients' room. This implies that it needs to consider the change of the person number per patient's room, from 5 persons to 4 ones. 5) The lacks of sleeping space, dining space, and bathroom space bothered the care-givers. This implies that the space for care-givers such as sleeping, dinging, and bathing should be considered in patients' room.

In this study, the change of critical elements of the design evaluation was investigated during two decades at the architectural competition which was held nationwide in Germany. Specifically, the periods of investigation span both from July 1989 to June 1990 and from July 2009 to June 2010. The results of the analysis show that the cost of construction, the maintenance cost, the design of facade and the energy conservation are being magnified for the new important elements. The images of buildings and the economic aspects are meant to be high. The frequency of the critical elements for interior spaces is approximately two times more important than those for the forms and outdoor spaces. Overall, many juries of the architectural competition in Germany were interested in the elements for interior spaces. The field of function accounts for roughly the half of four basic architectural fields such as function, others, aesthetic and construction fields. The critical elements are required persistently such as context, Circulation, organization of space, form, landscape and outdoor space design, arrangement of building, cost of construction, function, design of facade, location of main entrance. These items are regarded as the most important elements of the design evaluation at the competition. Knowing the change of critical elements of the design evaluation, we can understand the trend of architecture in Germany. The results of this study can be applied in Korea to develop the critical elements of design.

This study is to set up the appropriate range of observation time through contemplating the characteristics of observation time run for the information acquisition of space. The conclusions reached through this study are as the followings. First, this study could find out that even though the evaluation elements on the three types for image evaluation were the same, the information acquisitions were different as those types varied. On the other hand, the change of the average run-time by type for the information acquisition was found not to be big, in other words, even though the run-time was alike, the information acquisitions varied depending on the type. Second, he evaluation by language media showed the average value by element had the order of [shape>position>number>existence] and the range of their run-time was 94.6~102.9 seconds. The average rate of information acquisition shown at the visual media had the order of [composition>shape>material&color] and the range of run-time was 93.1~99.7 seconds. Third, the evaluation by language media showed that for male subjects the range of information acquisition rate was 39.1~91.4% and that of run-time 85.1~106.0 seconds and for female ones 46.0~94.6% and 96.3~112.3 seconds respectively. In case of the visual media, male subjects showed the range of information acquisition rate was 40.3-66.7% and the range of run-time 82.4~97.9 seconds and the female ones, 42.2~71.0% and 94.0~115.1 seconds respectively, through which we could see that at the evaluation by language media and visual media both the female's range of information acquisition and that of observation time were higher than the male's.
