Objective : The purpose of this study is to develop a personalized life safety prevention service mobile app, K-guard, that can protect the life safety of ordinary citizens, including persons vulnerable to safety, and to verify the effectiveness of the app. Methods : A model of life safety prevention service tailored to the persons vulnerable to safety was applied to an information service platform to prevent actual everyday life safety, and a satisfaction survey and usability evaluation were conducted on 107 subjects after conducting a demonstration service to 200 people in Seo-gu, Daegu-si, Republic of Korea. Results : As a result of the study, the most frequently used item among the app was the daily life risk notification, and 55.14% of the subjects used the app every day. As for the satisfaction level with K-guard confirmed through Mobile Application Rating Scale (MARS), usefulness of information was the highest with 4.15 points, followed by aesthetics with 4.13 points. In the usability evaluation conducted by dividing the subjects into groups of persons without disabilities, those with disabilities, and the elderly, positive responses were mainly low in the elderly group, and there was no significant difference in other groups. Conclusion : This study showed the possibility of developing a inclusive safety management system that can satisfy both persons with and without disabilities, and also confirmed the various needs of those vulnerable to safety that may further embody this possibility.
