Objective : The purpose of this study is to propose a customized accessible service structure for the preventive safety and disaster service information system according to the requirements derivation model proposed in the previous study, and presents an accessibility profile to utilize it. Methods : Through expert group meetings, the framework of customized information system services was derived, and based on the research results of Lee, Ji, and Kim (2020) and focus group interviews, the International Classification of Functioning, Disability and Health (ICF) customized service system was derived. Finally, an additional expert group meeting was conducted to derive the accessibility profile, which was revised and supplemented by advice from other expert groups. Results : The structure of utilizing the safety vulnerable accessibility profile was presented so that the safety vulnerable would not have any inconvenience in using the life safety prevention and response information service. This is a framework consisting of an expression layer and an information layer, wherein the expression layer provides information in a way acceptable to the user, and the information layer provides different information content according to the user's situation. The ICF-based safety vulnerable customized service system derived service requirements with a total of 36 codes. Finally, the accessibility profile for the vulnerable was derived from a total of 15 items in three areas: general information, medical information, and accessibility preference information. Conclusion : In this study, a method of customizing services tailored to various specific needs of users was proposed using the ICF classification system. This provided the basis for systematically preparing for a disaster by suggesting a solution considering the situation of various safety vulnerable people in establishing an evacuation plan for the safety vulnerable in the disaster preparation stage.
