COVID-19 is a new variant of SARS-COV-2 which can lead to mild to severe infection in humans. Despite the remarkable efforts to contain the epidemic, the virus spread rapidly around the world and its prevalence continued with different degrees of clinical symptoms in many countries. Although common strategies including prevention, diagnosis, and care are necessary to curb this epidemic, early and accurate diagnosis can play an important role in reducing the speed of the epidemic. In this regard, the use of technologies based on artificial intelligence can be of great help. For this reason, since the outbreak of COVID-19, many researchers have tried to use machine learning techniques as a subset of artificial intelligence for the early diagnosis of COVID-19. Considering the importance and role of using clinical and laboratory data in the diagnosis of people with covid-19, in this paper K-NN, SVM, decision tree, random forest, Naive Bayes, neural network and XGBoost models are the most common machine learning models, and a dataset containing 1354 records consisting of clinical and laboratory data of patients in Imam Hossein Hospital in Tehran has been used to diagnose patients with covid-19. The results of this research indicate that based on the evaluation criteria, XGBoost and K-NN models have the most accuracy among the mentioned models and can be considered suitable predictive models for the diagnosis of COVID-19.

The outbreak of COVID-19 has profoundly affected people's daily lives, and caused various challenges. Interactions of spouses has been one of the most important dimensions of life affected by these changes. The aim of this study was to identify the dimensions of women's experience of couple interactions during the restrictions imposed during COVID-19 pandemic. This research was conducted with a qualitative approach and a phenomenological method. The participants included 11 married women in Tehran who, during the restrictions caused by COVID-19, spent most of their time at home with their husbands. Data were collected using semi-structured and in-depth interviews. The data obtained from the interviews were coded and analyzed using the Colaizzi's method. The data were categorized into 18 sub-themes and three main themes. The findings showed that the potential of a couple relationship in crises can be such that individuals spontaneously do things to reduce the tensions in a way that this not only reduces the amount of stress, but also enriches their relationship. Women who had such an experience saw the forced situation of being together as a good opportunity to fix their relationship. But the spouses who did not have a normal couple relationship and did not have the necessary skills to repair the gaps and there has been tension, disconnection or overlapping roles and transgression of boundaries in their relationship, would make the gap in the relationship deeper with inappropriate reactions; therefore, this period has led to more conflicts for them.

The widespread deployment of social media has helped researchers access an enormous amount of data in various domains, including the the COVID-19 pandemic. This study draws on a heuristic approach to classify Commercial Instagram Posts (CIPs) and explores how the businesses around the Holy Shrine were impacted by the pandemic. Two datasets of Instagram posts (one gathered data from March 14th to April 10th, 2020, when Holy Shrine and nearby shops were closed, and one extracted data from the same period in 2019), two word embedding models – aimed at vectorizing associated caption of each post, and two neural networks – multi-layer perceptron and convolutional neural network – were employed to classify CIPs in 2019. Among the scenarios defined for the 2019 CIPs classification, the results revealed that the combination of MLP and CBoW achieved the best performance, which was then used for the 2020 CIPs classification. It was found out that the fraction of CIPs to total Instagram posts has increased from 5.58% in 2019 to 8.08% in 2020, meaning that business owners were using Instagram to increase their sales and continue their commercial activities to compensate for the closure of their stores during the pandemic. Moreover, the portion of non-commercial Instagram posts (NCIPs) in total posts has decreased from 94.42% in 2019 to 91.92% in 2020, implying the fact that since the Holy Shrine was closed, Mashhad residents and tourists could not visit it and take photos to post on their Instagram accounts.

Uncertainty, insecurity and complexity are some of the terms defining, now and in the future, the development process of the human species on planet Earth. There is plethora of evidence to substantiate this view. However, each epidemic has its own defining features, magnitude, and discernible impact. Societies are affected differently. It is shown that the events caused by the COVID-19 pandemic, called the "coronacrisis", directly affect the sphere of global economic (pandenomics) and political contradictions, including security issues. It is noted that the pandemic factor provoked an acceleration of confrontation between global players, strengthened the role of the institution of the nation state. In the context of deglobalization at the transregional level, under the slogans of "strategic vulnerability" and "economic sovereignty", nationalism and "protectionism 2.0" continue to grow, and multilateral international institutions continue to weaken. Against this background, the European Union seeks to achieve competitive advantages through the deoffshorization of production, industrial policy and the Green Deal. The article notes the deterioration of the state of affairs between Russia, China, the US and the EU. The article reveals further trends in the strategic decoupling of the United States and its European allies, draws attention to the incentives to implement the principle of "strategic autonomy" of Brussels.
