Introduction: There is a growing trend in online education coursesin higher education institutes. Previous studies have shown thathigh levels of self-direction are essential for successful onlinelearning. The present study aims to investigate challenges of andbarriers to self-directed virtual-learning among postgraduatestudents of medical sciences.Methods: 23 postgraduate virtual students of me...

background and purpose: in education of medical science courses, there has been a growing orientation towards replacing traditional teaching in with e-learning education. since the modern system of education is based on self-directed learning, e-learning requires special powers to deal with new-emerging challenges and professionally encounter the learning environment. the purpose of the present...

Abstract It has been proposed that we think of continuing medical education (CME) as a two-stranded helix, in which one strand represents the internal characteristics of the learner-physician, the other strand the culture and environment in which he or she practices and lives. In many countries, the product of these two strands has been increasingly termed ‘continuing professional development’...

the aim of this study was to compare three approaches of medical parasitological course. this cross sectional study carried out in 94 medical and pharmacy students. lecturer based learning, problem based learning, and combined approaches were used for teaching the parasitological course. kappa and spss16 were used to analysis. 82.9% of students were interested in lecturer based learning, 64.9% ...

one of the main challenges in wireless sensor network is energy problem and life cycle of nodes in networks. several methods can be used for increasing life cycle of nodes. one of these methods is load balancing in nodes while transmitting data from source to destination. directed diffusion algorithm is one of declared methods in wireless sensor networks which is data-oriented algorithm. direct...

p(X1:D|G, θ) (1) whereG is the graph structure (either directed or undirected or both), and θ are the parameters. In Bayesian modeling, we treat the parameters as random variables as well, but they are in turn conditioned on fixed hyper parameters α: p(X1:D, θ|G,α) (2) Clearly this can be represented as in Equation 1 by appropriately redefining X and θ. It will also be notationally helpful to d...
