Elderly nursing homes in South Korea are vulnerable to evacuation in emergency situations such as fires. There are many elderly residents with reduced self-walking ability, so if a disaster such as a fire occurs, it is very likely to lead to a large number of human injuries. In elderly nursing homes, it is impossible for many elderly people to evacuate voluntarily without the help of staff. Therefore, it is very important to guide the behavior of staff when evacuating. The purpose of this study is to evaluate the effect of evacuation behavior of staff on evacuation time in a fire emergency in an elderly nursing home by adopting an agent-based simulation approach. The effect of staff evacuation behavior on the evacuation time was investigated based on the results of a new agent-based evacuation simulation model. In the simulation model, there are conditions for caregivers to designate and evacuate the elderly, as well as to set the evacuation priority for the elderly. The results of this study show that having the elderly occupants designated by the staff according to their zones and evacuating them together was the most important in reducing the evacuation time. This study contributes to a new agent-based evacuation simulation model by confirming whether the evacuation behavior of employees affects the evacuation time.
University-affiliated public housing (UAPH) is planned for the purpose of coexistence with the local community as well as housing stability for university students. However, shared spaces such as auxiliary welfare facilities planned to achieve that purpose are not being used by residents because no services or programs are provided. Lifestyle is a useful approach for identifying housing preferences in housing projects for special groups that share similar demographic characteristics. Thus, this study analyzed and clustered the lifestyle of university students, and investigated the differences in preferred auxiliary welfare facilities and residential services by cluster. Data were collected through a self-administered questionnaire survey of 424 university students using an online survey. As a result of the survey, in the factor analysis of university students’ lifestyle types, three categories were identified as individual propensity factors regardless of demographic characteristics except gender. In addition, the characteristics of university students were crucial in examining the preference of auxiliary welfare facilities and residential services of UAPH in terms of community facilities, auxiliary facilities, residential services, and program/operation management. Community facilities showed a high need for academic facilities, a low overall need for residential services, and a high need for program/operational management in terms of cost (housing cost reduction). In this study, there were differences in UAPH opinions according to lifestyle. In particular, many respondents showed a lifestyle that pursued practicality, and accordingly, a preference to utilize practicality, sociality, information, and technology was high. Therefore, for the sustainable operation and management in order to facilitate UAPH construction, the issue of housing cost, including not only rent but also management costs, should be considered most fundamentally, and it is necessary to provide facilities and programs that can provide practical help to the difficulties students face when living alone.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
