Oxidative C–H Functionalization of Arenes: Main Tool of 21st Century Green Chemistry. A Review

Vision is perceived to be the most important human sense. For people, this is the main tool for learning because we use it to get 80% of the information we need. However, over time, vision deteriorates or is lost due to age-related, genetic or unpredictable factors such as trauma. Therefore, it is very important for us to have technologies for effective treatment of diseases that lead to vision loss. This article introduces the reader to a new and promising method of treating eye pathologies using microrobots.

Proficiency Level

The pandemic phenomenon has forced the world of education to change the work pattern of services from conventional to online-based education and learning services. This study aimed to describe and analyze the level of teachers’ 21st century proficiency and its effect on teachers’ performance in online learning due to Covic-19. This research was conducted at the Alkautsar Integrated Islamic Education Foundation School, with a population of 90 teachers and a sample of 68 teachers. This is a descriptive quantitative research conducted by a survey design. The main tool for data collection is a questionnaire. Data were analyzed using descriptive statistics by calculating the mean value of teachers' 21st century competence and teachers’ performance in online learning due to Covic-19. Inferential statistical analysis was also carried out to find the magnitude of the relationship and influence between variables. The results showed that the average score of level of teachers’ performance in online learning was 3.56 in the high category. The 21st century proficiency level of teachers with a mean value of 3.72 was also in the high category. It was also found that there is a significant relationship between 21st century proficiency variables and teachers’ performance in online learning of 0.809. The effect of 21st century skills on teachers’ performance in online learning was 65.50%. The conclusion is that the better the 21st century skills of teachers, the better the teacher's performance in online learning due to Covid-19.

Human brains are biological, biophysical, neurophysiological and medico-social paradigms of information exchange. Modern communications are multilevel, multi-paradigm and interdisciplinary models of information exchange. The new competencies of psychoneuroimmunoendocrinology and psychoneuroimmunology play a strategic role in interdisciplinary science and interdisciplinary planning and decision-making. The introduction of multi-vector neurotechnologies of artificial intelligence and the principles of digital health care will contribute to the development of modern neuroscience and neuromarketing. Neurogenetics is a center for multidisciplinary and interdisciplinary research using advanced methods, with the participation of 5P Medicine and 5G technology. Human genome sequencing was an important scientific milestone that revolutionized biology and medicine. The Human Genome Project is a neurogenetic routing from the 20th to the 21st century, numerous discoveries due to the collaboration between discerning clinicians and technically innovative fundamental scientists. Genomic engineering, genome editing and gene editing refer to modifications (inserts, deletions, substitutions) in the genome of a living organism. Modern genome editing is based on clustered regularly alternating short palindromic repeats and associated protein 9 (CRISPR-Cas9). In prokaryotes, CRISPR-Cas9 is an adaptive immune system that naturally protects cells from viral DNA infections. CRISPR-Cas9 has been modified to create a universal genome editing technology that has a wide range of applications in medicine, agriculture and basic gene function research. sleep is the main tool and mechanism in the formation of cognitive memory, its quantitative and qualitative volume, the integration of the transition to a qualitatively new level of self-development and self-improvement, which allows you to create a new intellectual “qualifying mind”. The 21st century Homo sapiens will have the ability to understand physiological and neurophysiological sleep patterns, manage and change their sleep habits. Digitization of sleep is the future for the development of industry, health, science and personalized health.
