Over the last few decades, both developed and developing countries have an increasing trend in technology but with an enormous gap, particularly in the education sector. The e-learning following institutions can achieve benefits by evaluating their e-learning readiness through up-front analysis. Moreover, several models have been introduced to measure e-learning readiness for developed countries but these are not adequate for developing countries.  This paper introduced the e-learning readiness evaluation model for the developing country, Libya, by considering the primary education sector. Furthermore, this study examines the e-learning level of readiness in the staff of the primary school. The purpose of this study is to evaluate the e-learning readiness of staff by directing factors of e-learning readiness i.e. cultural readiness, content readiness, and technology readiness. To achieve this objective, this paper collects data through questionnaires, and respondents are 110 staff member of primary schools in Yefren, Libya. Therefore, the multivariate analysis shows that the e-learning readiness factors have e significant relationship with the adoption of e-learning because most teachers are well prepared and ready. Likewise, results indicate that technology is the most significant factor instead of other e-learning readiness factors. According to the views of staff, there should be more content development training required for primary school staff. Thus, the demographic structure is inadequate to enhance the e-learning but the staff is ready for e-learning.

The application of machine learning technologies for cancer detection purposes are rising due to their ever-increasing accuracy. Melanoma is one of the most common types of skin cancer. Detection of melanoma in the early stages can significantly prevent illness and fetal death. The application of innovative machine learning technology is highly relevant and valuable due to medical practitioners' difficulty in early-stage diagnoses. This paper provides an open-source tutorial on the performance of an algorithm that helps to diagnose melanoma by extracting features from dermatoscopic images and their classification. First, we used a Dull-Razor preprocessing method to remove extra details such as hair. Next, histogram adjustments and lighting thresholds were used to increase the contrast and select lesion boundaries. After using a threshold, a binary-classified version of image was obtained, and the boundary of the lesion was determined. As a result, the features from skin tissue were extracted. Finally, a comparative study was conducted between three methods which are Artificial Neural Network (ANN), Support Vector Machine (SVM) and K-Nearest Neighbor (KNN). The results show that ANN could achieve better accuracy (83.5%). In order to mitigate the biases in existing studies, the source code of this research is available at hadi-naghavipour.com/ml to serve aspiring researchers for improvement, correction and learning and provide a guideline for technology manager practitioners.

در دوره استیلای مغول، با به خطر افتادن امنیت مردم و لرزان شدن پایه های زندگی اجتماعی و فردی، ارزش های اخلاقی تا حدودی رو به انحطاط رفت؛ زیرا بارزترین انواع امنیت- که در پناه آن می توان آسوده زندگی کرد- مانند امنیت اجتماعی، اقتصادی، شغلی، فردی، قضایی، روانی و فرهنگی، همگی دچار سیر نزولی شدید شدند و با تنگ شدن عرصه زندگی بر ایرانیان، مبارزه آنان با حاکمان مغول به مبارزه برای بقا تبدیل شد و مسئله فرهنگ و اخلاق اصیل به مرتبه دوم سقوط کرد.البته باید اذعان کرد که مغولان علت تامه انحطاط اخلاقی نبودند، یعنی نمی توان همه نابسامانی ها در این حوزه را به آنان منتسب کرد؛ اما روش حکومت و سیاست گذاری های آنان به گونه ای بود که منجر به تشدید این انحطاط شد؛ انحطاطی که از قبل آغاز شده بود.پس از پایان حاکمیت مغول، تمامی خسارات در حوزهای سیاسی، امنیتی، اقتصادی، شغلی و... جبران شد، اما خسارت های اخلاقی تا مدت ها پایدار و پابرجا بود؛ به گونه ای که بعضی صاحب نظران معتقدند که تاکنون نیز تأثیر اقدامات آنان در لایه های زیرین تفکر و فرهنگ ایرانی مشهود است.در این مقاله، با روش تحلیلی به تبیین این موضوع می پردازیم.
