The main objective of this review was to investigate whether educational attainment has an impact on the occurrence of atrial fibrillation (AF) as well as the implementation of smart technology to detect this condition. Data on the relationship between education level and the occurrence of AF were collected, as well as data on smart devices for detecting AF. A lower level of education has been linked to an increased risk of AF. With this in mind, it is easy to explain the clear correlation between education level and AF, as well as the adoption of smart device detection and how it may improve illness prognosis. People with a higher level of education understand and embrace the notion of employing smart devices to detect and prevent AF; they also have decreased AF prevalence compared with those with a lower level of education.

Atrial fibrillation is the most commonly experienced type of cardiac arrhythmia and is the most associated with substantial clinical occurrences and expenses. This arrhythmia often occurs in its "silent" asymptomatic form, revealed only after complications such as a stroke or congestive heart failure have transpired. New smart devices confer effective advantages in the detection of this heart arrhythmia, of which photoplethysmography-based smart devices have shown great potential, according to previous research. However, the solution becomes a problem as widespread use and high availability of various applications and smart devices may lead to substantial amounts of false and misleading recordings and information, causing unnecessary anxiety regarding arrhythmic occurrences diagnosed by the devices but not professionally confirmed. Thus, with most of the devices being photoplethysmography based for detection of atrial fibrillation, it is important to research devices studied up to this point to find the best smart device to detect the aforementioned arrhythmias.

– Homeschooling is a term typically used to describe the form of education where parents educate their own children at home with little to no contact with public school education. The purpose of this study is to gather information on the public opinion of homeschooling in Sarajevo Canton, Bosnia and Herzegovina, as well as to see how the COVID-19 pandemics affected this opinion. For this purpose, a survey was conducted and, as a result, information on the topic is gathered. The general opinion of the public leaned more towards the negative end when all the results were summarized. Homeschooling, in general, is not a term that people are familiar with and accepting of in t h e region of Sarajevo Canton, Bosnia and Herzegovina. Additionally, the COVID-19 pandemic has not had a positive influence on the opinion of the homeschooling.

Effect of 11 commercially available food coloring dyes was tested on referent bacterial strains: Staphylococcus aureus ATCC 25923, Pseudomona aeruginosa ATCC 27853, Escherichia coli ATCC 25922 and Enterococcus faecalis ATCC 29212. Mueller-Hinton agar was used as media for bacterial growth to which different concentration of food coloring dyes were added. Two different types of food coloring dyes were used, powder and gel. The results indicated that different food dyes have different effect on bacterial growth due to difference in their ingredients, such as sugars, coloring and emulsifiers. Difference in growth, on media containing food coloring dyes, was also noticed between Gram-negative and Gram-positive bacteria.

:- The most commonly experienced cardiac arrhythmia and the most associated with significant clinical occurrences and expenses is Atrial fibrillation (AF) . Predominantly Due to advances in diagnosis methods, AF has been reported a greater and increasing frequency. By 2030, 14 – 17 million AF cases are anticipated in the European Union, with 120 000 – 215 000 newly diagnosed patients per year. Estimates suggest approximately 3% of adults aged 20 years or older are likely of contracting the condition. AF is independently associated with a two-fold a doubly increased risk of all-cause mortality in women and a 1.5-fold increase in men. The silent form of AF is incidentally diagnosed during routine physical examinations, pre-operative assessments, or population surveys. Unfortunately,, in certain cases, silent AF is revealed only after complications such as a stroke or congestive heart failure have transpired. New smart devices present impactful advantages in the detection of this cardiac arrhythmia. However, the widespread use of these devices, and the large number of free apps with varying degrees of certification, may lead to a great amount of misleading information causing anxiety about arrhythmic occurrences diagnosed by the devices but not professionally confirmed. The possibility of illegitimate or inaccurate results causing panic in the general population would merely convert a solution into a problem. Therefore, it is important to find the best smart device for detection of atrial fibrillation.
