Evaluating the Acceptance of Massive Open Online Courses (MOOCs) among Students of Shiraz University of Medical Sciences
Mohammad Hossein Ronaghi,
Volume 13, Issue 4 (Oct & Nov 2019)
Abstract
Background and Aim: MOOC stands for Massive Open Online Course and is an instructional approach that allows hundreds of thousands of students to access -- typically free of charge -- online courses anywhere around the world. The continuous and rapid growth of MOOCs has attracted the attention of educational community and has gained widespread popularity among many universities. Therefore, based on the Unified Theory of Acceptance and Use of Technology (UTAUT) model, an applied research was conducted to study medical students' acceptance to use MOOCs.
Materials and Methods: It is a descriptive survey that has been done in 2019. The sample consisted of 367 randomly selected students of Shiraz University of Medical Sciences (SUMS). The data collection tool was a questionnaire, the validity and reliability of which were confirmed. The data were analyzed by SPSS and LISREL 8.8 software.
Results: An important part of the results revealed that there was a positive meaningful relationship between "performance expectancy" and "behavioral intention", "effort expectancy" and "behavioral intention", "facilitating conditions" and "use of the system", and "behavioral intention" and "use of the system".
Conclusion: According to the results of this study, MOOC managers' motivation to implement the system effectively strongly depends on the behavioral intention of users, especially students' willingness to accept and use the system.

Security Challenges in Fog Computing in Healthcare
Mohammad Hossein Ronaghi, Foroughosadat Hosseini,
Volume 14, Issue 1 (Apr & May 2020)
Abstract
Background and Aim: The Fog Computing is a highly virtualized platform that provides storage, computing and networking services between the Cloud data centers and end devices. Fog computing fits the characteristics of real-time health monitoring systems. In such systems, a large amount of data is acquired from a multitude of bio and environmental sensors. On the other hand, its distribution and open structure makes it vulnerable and weak to security threats. Therefore, the aim of this paper was to identify the security challenges in healthcare.
Materials and Methods: This applied research has been done in three phases using mixed-method approach in 2019. In the first phase, security codes from library resources by content analysis was identified. In the second phase interpretation of experts by Delphi method, Panel of IT experts consists of twelve members who work on healthcare sector was evaluated. Finally, we used Analytic Hierarchy Process method for ranking security codes.
Results: According to fuzzy AHP results attacks(0.31), secure communications(0.23), authentication and access control(0.19), trust(0.15) and privacy preservation(0.12) are the most important criteria in security challenges of fog computing.
Conclusion: According to the results of this study, secure communications and network attacks are the major challenges in fog computing, because fog nodes are usually deployed in some places with relatively weak protection. They may encounter various malicious attacks. As a result, policymakers should be aware of the role of secure communications and network attacks in fog computing implementation.

Application of Augmented and Virtual Reality Technologies in Medicine
Mohammad Hossein Ronaghi,
Volume 14, Issue 5 (Dec & Jan 2021)
Abstract
Background and Aim: Virtual Reality and Augmented Reality are immersive technologies that integrate virtual and real-world elements. These technologies have been used to help and improve human capabilities in many fields. Virtual and augmented systems are used in various medical situations. They are effective options in most stages of patient treatment and performing medical procedures. Therefore, the purpose of this study is to investigate the applications of virtual and augmented reality technologies in the field of medicine and rank them.
Materials and Methods: This applied research was conducted in two phases using mixed-method approach in 2020. Library resources were used in the qualitative phase and a questionnaire in the quantitative phase. The applications of virtual and augmented reality technologies were ranked by a panel of experts having 13 members. Finally, Stepwise Weight Assessment Ratio Analysis(SWARA) method was used to rank the applications of technologies in medicine.
Results: The results of SWARA method showed that education (0.252), surgery (0.216), health games (0.188), patient control and diagnosis (0.186), and pharma (0.158) were the most important applications of virtual and augmented reality in medicine.
Conclusion: Based on the results of this study, it can be acknowledged that medical education and surgery are the most important applications of augmented and virtual reality technologies in medicine. Therefore, policymakers and hospital managers must use this ranking for the development of virtual and augmented reality technologies in their organization to provide better services to the customers and patients.
