노약자를 위한 접근가능한 디자인 요소별 비용정보제공에 따른 선호도 분석

Preference studies the elderly housing were conducted to find out design features in specific needs of certain elderly groups of demographic characteristics. The purpose of this study was to investigate preference for accessible design features for the elderly and find out the differences in preference whether the cost information was given or not. Contrast to the previous studies, we suggested some alternatives to fulfill the accessible goals. Preference for each option was investigated and differences in preference with its cost information was also investigated. The total of 700 questionnaires were collected and analyzed using SPSS 18.0. In order to remove level differences, respondents prefer installation of trench to installation of deck or ramp. When people received the cost information, the proportion of selection for each option has slightly changed. The findings of the study suggest that cost information is an important factor for choosing the option for removal level difference, sink design and holding bars and installation of elevator. Regardless of age and cost information given, the respondents prefer sliding door option, one of the door option for bath room. It may be due to the relative small area for its installation. It was found that when people recognized the importance of the accessible design features higher, they are likely to choose the option which cost is higher. The higher people evaluate the importance of accessible design features, the more they can pay for the option. In general, for the preference of alternatives, there are significant differences between the elderly and the younger.
