With the expansion of Internet access and the provision of communication between researchers, the demand for research methods based on this structure is increasing. With the development of the Internet, the limitations of many research methods, such as Delphi-which are often limited to geographical boundaries-have been reduced, paving the way for the emergence of new implementation methods. E-Delphin is a qualitative method and online to respond to the growing needs of science to experts ‘ consensus. Despite all advantages of this method, many Researchers are unfamiliar in many disciplines, such as medical and health education. A large part of it is related to the ignorance of this method in general and the other part is related to the methodological issues and the qualitative nature of this method is related to the ignorance of this method in general and the other part to the methodological issues and the qualitative nature of this method. The scientists who intend to use this method will face with several challenges, which include limited educational resources in the implementation of this method, lack of general consensus on the quality and framework of research rounds, the problem of generalizability of results, lack of Specialized and free websites in this field, the challenge of access to the Internet for all researchers or experts, conventional technical problems, Mechanisms for issuing round information in order to enter the computer and analyze, the measuring problems of the consensus, theoretical saturation and the risk of false saturation, this method interferes with some other techniques like survey, the need for the researcher's relative mastery of the subject matter. But despite all these shortcomings, the unique advantage of E-Delphi is that it is able to predict the future and fate of an issue such as the future of technology, a training method, or a treatment protocol over the next few years or decades.

In this paper the traditional and state-of-the-art educational methods and experience in teaching of power electronic devices for undergraduate students are described. The main attention is dedicated to possibilities how to improve the study using e-learning methods. The interactive screens with animations created for better understanding features of power semiconductor devices are presented.

In the era of "professional work and rapidity of its performance", it is very important to note that the players should know the principles, rules and regulations of the game very well. It should be noted that there is a complete difference between working more intelligently and working more or harder. An intelligent work means the maximum usage of possibilities, equipment and time; The latter is the most important among all. The article is a realistic view over this subject; In fact it is the result of the study, research and finally the expertise sessions held by the elite in this field ( for three years) with the presence of different car Electronics in not too long ago. The aim of this article is not to open up the theoretical backgrounds, but it is going to provide a perspective, though briefly, in the field of car Electronics and utilizing the patterns in their suitable stand in order to make this view practical (from Electronics point of view , suggested methods for upgrading homemade car production).Nowadays, governments are trying to control the amount of toxic, dangerous and harmful pollutants production by the ecology rules and regulations. Of course, in these societies, considering their limited resources in huge economy, it is an undeniable necessity to save as much fuel as possible from one side, and considering the possibility of satellite connection and suitable communication infrastructures, a car is not taken as a mere transport means from the other side.

Introduction: The aim of the present study was to develop a hospital management information system (HMIS) as the infrastructure for establishing and deploying an electronic HMIS (eHMIS). Its deployment can lead to the achievement of integrated hospital information as well as reliable and timely statistical indicators of the current information system using efficient, new, and effective technology in the field of hospital management. Methods: This research was conducted in a mixed method in two parts of qualitative-comparative and qualitative-two-steps Delphi in year 2017. The research population was selected based on non-random sampling through a targeted sampling method among 30 experts in Mazandaran University of Medical Sciences, Sari, Iran. Results: The 10-step WHO-based HMIS development strategy consisted of 12 principles, 62 steps, and 28 worksheets. Experts agreed on the principles and steps in the initial model and the final model, and no changes were made. Corrections were made only in the worksheets section, and the number of worksheets increased in steps 1, 2, 6, and 9. Conclusion: In order to establish an eHMIS, there is a need to design the infrastructure of the current hospital information system. The proposed solution can be used as a simple and quick manual and mechanized application to provide the infrastructure of the current hospital information system.
