background: there can be little doubt that the construction is the most hazardous industry in the worldwide. this study was designed to modeling the factors affecting unsafe behavior from the perspective of safety supervisors. methods: the qualitative research was conducted to extract a conceptual model. a structural model was then developed based on a questionnaire survey (n=266) by two stage ...
with rapid economic development and industrialization, the construction industry continues to rank among the most hazardous industries in the world. therefore, construction safety is always a significant concern for both practitioners and researchers. the objective of this study was to create a structural modeling of components that influence the safety performance in construction projects.we f...
data envelopment analysis (dea) measures the relative efficiency of a homogenous set of decision-making units (dmus) when multiple inputs and outputs are present. the deabased malmquist productivity index measuring the productivity change of dmus over time has proven itself to be a valid tool to compare group performance. however, in the previous models developed for this purpose, it was suppos...
Background: Every year, accidents and disasters occur in Iran and result in death and injuries of common people. People’s demand for health care units involves not only the requirement for medical centers but also staffs to work in them. Therefore, the purpose of this study is to investigate the performance readiness and non-structural functional safety of different health care centers an...
Introduction: Patients’ safety culture indicates the extent to which the staffs prioritize the safety of patients. In medical centers, it is very important to pay attention to the patients’safety. Hence, the patients’safety culture should be examined and improved. One of the factors which lead to the improved patients’ safety culture is structural empowerment. Structural empowerment refers to a...
In this paper a fuzzy method for determining appropriate structural design is presented. Non-stochastic uncertainty is quantified using fuzzy values and fuzzy random variables. Fuzzy structural parameters are processed on the basis of a generally applicable numerical method for arbitrary nonlinear fuzzy structural analyses. Fuzzy randomness is introduced into a fuzzy probabilistic safety assess...
Background: Organizational success depends on leadership style. Leadership style probably affects coronavirus anxiety and workers’ safety behavior at work. This study aims to examine the structural association between leadership style and coronavirus anxiety with safety behavior among workers in the sanitary products industry in Qom Province. Materials & Methods: This descriptive-correlative s...
Background and Aim: The disasters and emergencies can pose major challenges to the health infrastructure. Hospitals are the main units for providing health services in response to disasters. Considering the vital role of military hospitals in responding to disasters, the present study was conducted with the aim of explaining the improving strategies of disaster risk management in military hospi...
BACKGROUND AND OBJECTIVE Iran's hospitals have been considerably affected by disasters during last decade. To address this, health system of I.R.Iran has taken an initiative to assess disaster safety of the hospitals using an adopted version of Hospital Safety Index (HSI). This article presents the results of disaster safety assessment in 224 Iran's hospitals. METHODS A self-assessment approa...
In this paper, a procedure has been introduced to the multi-objective optimal design of semi-active tuned mass dampers (SATMDs) with variable stiffness for nonlinear structures considering soil-structure interaction under multiple earthquakes. Three bi-objective optimization problems have been defined by considering the mean of maximum inter-story drift as safety criterion of structural compone...
