Today, digital transformation is changing the educational and social life rapidly. In contrast, organizations and educational institutions, developers, and end users do not benefit from cloud-based mobile technologies to the desired level. Mobile systems are used extensively for educational purposes in the Internet of Things (IoT) environment, and the number of online students is increasing. The real problem is how user-friendly, aesthetic mobile learning courses can be effectively delivered on different mobile devices in the desired performance and manner. The responsive design developed with fog computing should be able to provide the ability to design and use mobile learning lessons with sufficient performance, automatically adapted to any browser or device. This should ensure that every person of the target audience can benefit from the lessons without worrying about screen size, resolution, speed and even security. In this study, the fog informatics teaching strategies of mobile learning sensitive teaching design are discussed. The fog computing architecture that can be used with responsive mobile learning, utilizing mobile computing to provide seamless and low latency mobile devices, is described. Finally, a fog-based, responsive designed mobile learning education architecture has been compiled with a better understanding of the lessons and a suitable structure for the use of mobile devices in education.

Responsive design allows users to benefit from the web page without having to worry about screen size and resolution. The aim of this study is to investigate the effect of responsive design on usability. For this purpose, a questionnaire consisting of a five-point Likert was applied to university students. According to the results, it was seen that 99.2% of university students had smart phones and used smart phones to connect to internet with a rate of 91.3%. It was observed that the participants' attitudes towards responsive design did not differ according to gender, and students in the 24-26 age group had more desire to use responsive design. And, university students' attitudes towards responsive design did not differ according to the Internet access method. It was found that 38% of the participants had a daily internet usage rate of 4-5 h and they used social media the most. Ease of use has been identified as the most preferred feature (Avg = 3.67/5, 73.4%) of usability in responsive design by evaluating dimensions central tendency measures. With regression analysis, responsive design explains 74.7% of the change in effectiveness (R 2 = 0.747) among the usability dimensions. With regression analysis, 91.5% of usability can be explained with the responsive design (R 2 = 0.915). Usability and responsive design (r = 0.92, p < 0.01) were both found to be positively correlated. It can be said that the academic university websites developed with responsive design are preferred by university students in the pandemic and this has increased usability and effectiveness.

This study proposes an e-learning framework for Turkish Family Medicine (FM) physicians by requirement analysis using e-learning survey and program educators' interview. The main data collection was done with an online survey complemented by a structured interview. According to the outcomes of e-learning survey, the Khan framework was modified with Mobile/Wireless Technologies, Time, Content Control, Delivery Method dimensions. The program educators declared that their opinions for potential solutions as getting training for e-learning; increasing human resources capacity for support; implementing training in asynchronous format; accepting online learning culture; eliminating hardware, software and connection problems; increasing financial support; getting managerial implementation support and improving personal rights.

Generally it is not easy for an instructor to prepare and deliver electronic courses via elearning. Therefore it is necessary to work and develop an easy system. In this context module technology was used to for provide modularity in conducting educational development of elearning course. Then, rapid e-learning was used for more quick and easy course development. In order to implement modular rapid e-learning, a desktop virtual environment was set up. Modular rapid e-learning was used by teachers and students in a one semester course and student success and reactions were evaluated. And also the overall hybrid system cost was calculated and reported. In implementation we combined modular course design with rapid elearning and desktop virtualization in education of 3 rd year nursing students for a one semester course. The effectiveness of this hybrid method was evaluated with respect to students' success, students' opinions and over all cost effectiveness. It was seen that the hybrid method was educationally more effective than traditional method comparing with previous year students' success and fit with students' requirements. The cost reduction was %41 comparing with traditional desktop and e-learning system.

Anbar 2001). Online shopping is cheaper in some parts of the retail sector, access to website with fast access, finding products, price comparisons, 24/7 shopping opportunity, gift and discount days make e-commerce attractive (Uğur 2016). In addition to its attractive features, some negativities are experienced and these situations cause customers to hesitate to shop online and avoid using it (Demirel 2010).In this study, examining the factors of electronic commerce affecting the use of online shopping websites is among the most important aims of the research. The purpose of this research is to evaluate the aspects of online shopping that need to be improved for customers during the pandemic. Issues such as shipping and tracking, website security, customer satisfaction, ease of use, which have an important place in the e-commerce ecosystem, need to be improved in order to determine customer
