During the last months of the coronavirus pandemic, with all those public restrictions and health interventions, the transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) appears now to have been raised in some countries around the world. Iran was one of those first countries facing the second wave of coronavirus, due to the lack of appropriate public restrictions because of economic problems the country is facing. The clinical and demographic characteristics of severe cases and non-severe cases of Coronavirus Disease (COVID-19) in 192 patients in Tehran, Iran, between June 16 and July 11, 2020, were investigated. The patients were divided into severe cases (n = 82) and non-severe cases (n = 110). Demographic and clinical characteristics were compared between the two study clusters. The mean age was 54.6 ± 17.2 years, and the most common presenting symptom was persistent cough (81.8%) and fever (79.7%). The logistic regression model revealed that age, BMI, and affected family members were statistically associated with severity. Patients with complicated conditions of disorders faced more hospitalization days and medical care than the average statistical data. As the coronavirus spike in the case and death reports from June 2020, we observed the rise in the incidence of severe cases, where 42.7% (82/192) of cases have resulted in severe conditions. Our findings also suggested that the effect of IFB (Betamethasone) was more valid than the other alternative drugs such as LPV/r and IVIg.

<p><strong>Abstract.</strong> An area cartogram is one of the cartographic presentation forms. It is a unique way of presenting statistical data, in which the surface of the individual spatial units is proportional to the value of the phenomenon. Due to its specificity, the area cartogram is an interesting way of graphical representation of phenomena, in particular, the demographic and economic problems of the world.</p><p>In my research, I discuss an empirical study that I have conducted among pupils of the secondary school in Poland. On the basis of the list of advantages and disadvantages of area cartograms collected by B.D. Denta (1999), I assumed that contiguous area cartograms seem to be more useful in teaching in the secondary schools than non-contiguous cartograms. I compared the three types of contiguous area cartograms (preserving the spatial continuity of the presentation, having no gaps between neighboring units &amp;ndash; Figure 1): square cartograms, mosaic cartograms and diffusion-based cartograms (Gastner-Newman algorithm).</p>

Abstract Objective: Numerous cases of COVID-19 were confirmed in the world in succession. We reported the epidemiological and clinical features of 478 confirmed cases from a multicentre study outside of Wuhan, China. Methods : We collected patients who were transferred by Emergency Medical Service to the designated hospitals in four major cities including Beijing, Chongqing, Jinan and Nanning in China. We compared the characteristics between imported and indigenous cases, and calculated the fatality, and the rate of severe cases, mild and asymptomatic cases to generate the pyramid of COVID-19 infection. Results : The mean age of patients was 46.9 years old and 49.8% were male. The most common symptoms at the onset of illness were fever (69.7% ), cough (47.5%), fatigue (24.5%), dyspnea (8.4%) and headache (7.9%). In the study, most cases (313, 65.5%) were indigenous, while 165 (34.5%) were imported. During the early stage, the imported cases were dominant, which declined from Feb 1, when the indigenous cases rise sharply. Compared with the indigenous cases, the imported cases were significantly distinct concerning gender composition (P=0.002), classification of severity (P=0.006). Conclusions : On the basis of this study, we suggest that preventing import from outside and controlling spread inside should be a basic principle for resisting COVID-19 infection. If not, the region or area will face chaos.

In order to model within-person (WP) variance in a reaction time task, we applied a mixed location scale model using 335 participants from the second wave of the Zurich Longitudinal Study on Cognitive Aging. The age of the respondents and the performance in another reaction time task were used to explain individual differences in the WP variance. To account for larger variances due to slower reaction times, we also used the average of the predicted individual reaction time (RT) as a predictor for the WP variability. Here, the WP variability was a function of the mean. At the same time, older participants were more variable and those with better performance in another RT task were more consistent in their responses.

Second Wave

With signs of normalization seemingly in place in the world economy, a number of problems show the possibility of aggravation in the future. The volume of derivatives in American banks grows significantly, high risk instruments are back in place and their use becomes more active, global imbalances increase. All of the above requires thorough approaches when creating mechanisms which can neutralize external shocks for the Russian economy and make it possible to develop in the new post-crisis environment.

The implementation ofthe capitalist system has eliminated the Islamic values in economic practice. After the financial crisis hit the world, the capitalist system reaped many questions and its greatnessbegins to be doubted. The capitalist system implementationprecisely creates new problems in the economy. The concept of individualism which is the main key in capitalist practice only creates economic injustice and misery of the poor. The only economic theory that is expected as a light in dealing with economic problems is an economic system that is able to create justice,the welfare of all parties and blessings both the world and the hereafter. The theory is the Islamic economics which in practice is inseparable from Islamiceconomic law. Islamic economic law that underlies the Islamic economic system is totally different from the capitalist economic system.Keywords: Islamic Economic Law; Islamic economics; Capitalist Economy

The research describes one of the approaches to designing a productive mechanism for migration temperature control considering it as an integral qualitative and quantitative indicator of the social and economic problems level associated with migration processes. The analysis of various approaches to studying migration processes impact on socioeconomic situation in recipient countries has been carried out. Some cognitive models have been developed basing on the questionnaire results’ analysis, expert assessments, statistical data. A series of simulation experiments have been carried out using software specially developed to automate the cognitive modeling processes.In the course of our experiments, some changes in the target factor. i.e., in migration temperature, have been detected as a result from different intensity impulses impacting on individual controlling factors. Within the developed models framework, several proposals have been put forward concerning the productive mechanism for migration temperature control.

Descriptive Survey

This study was carried out to determine the modern office technology competencies expected of office technology and management (OTM) graduate workers by supervisors in Delta State. The study was guided by two research questions and two hypotheses tested at 0.05 level of significance. The respondents consisted of 142 supervisors, made up of 74 heads of department and directors of government establishments, and 68 managers and directors of private establishments in the study area. Descriptive survey research design was used to conduct the study and 28 – items questionnaire were used to collect data from respondents. The instrument was validated by three experts and had a Cronbach Alpha reliability coefficient of 0.77. Means with standard deviations were used to answer the research questions, while t-test was used to test the null hypotheses. The extent of supervisor‟s expectations of information processing competencies did not differ significantly based on the mean ratings of male and female supervisors of OTM graduates in government and private establishments. The findings also revealed that supervisors expect much information processing and communication competencies from the OTM graduate workers. Based on the findings and the implications, it was recommended among others that, curriculum planners, business and OTM education lecturers should ensure that the competencies required for modern office technologies are entrenched and taught in the institutions to prepare the OTM graduates for the world of work.
