“…The third human experimental study passing our basic quality criteria did neither find any effects from WiFi exposure on spontaneous awake electroencephalographic activity and psychomotor vigilance (Zentai et al, 2015). No effects were found also in the fourth human experimental study, which investigated reaction time, short-term memory and reasoning ability (Hosseini et al, 2019). Thus, from these four studies acute effects of WiFi at levels typically occurring in the environment are unlikely, even in EHS individuals.…”

“…In a crossover study with 32 female and 13 male participants in Iran, effects of WiFi exposure on reaction time, short-term memory and reasoning ability were investigated (Hosseini et al, 2019). Based on one sham and one exposure session, each lasting two hours, no significant differences between the mean scores of reaction time, short-term memory, and reasoning ability were found.…”

Although WiFi contributes little to total radiofrequency electromagnetic field (RF-EMF) exposure in our everyday environment, concern has raised whether this specific type of modulated RF-EMF causes health problems. The aim of this review is to evaluate all types of studies that investigated biological and health effects of WiFi exposure and fulfilled basic quality criteria. Eligible for inclusion were epidemiological, human experimental, in vivo and in vitro studies using realistic WiFi exposure settings. We conducted a systematic literature search for all papers published between January 1997 and August 2020 followed by a quality review addressing blinding and dosimetry in experimental studies and various types of biases in epidemiological studies. All studies fulfilling the quality criteria were descriptively summarized in terms of observation or absence of associations. From 1385 articles identified by the literature search, 23 fulfilled basic quality criteria: 6 epidemiological papers, 6 human experimental articles, 9 in vivo articles, and 2 in vitro articles. Whereas in vivo and in vitro studies applied exposure levels up to 4 W/kg, human studies dealt with exposure levels several orders of magnitude below the ICNIRP guidelines, which are typical for WiFi exposure situations in the everyday environment. Numerous outcomes ranging from biological markers to symptoms were mostly found not to be associated with WiFi exposure. Sporadic findings were not consistent in terms of outcomes or exposure-response associations. This review based on a systematic literature search and quality evaluation does not suggest detrimental health effects from WiFi exposure below regulatory limits.

“…We conducted a study on VSTM (visual short-term memory) and ASTM (auditory short-term memory) based on two pairs of aspects: numerical and visual, which is different from many authors who only studied VSTM and ASTM using only numerical data [10], [11], [12], [13]. The questionnaire was built based on the Nechaiev method similar to the study of Tran Long Giang [7]. Some studies on ASTM and VSTM in the form of numbers by Nguyen Phi Ho, Ngo Thanh Trang, and Pham Thi Huyen Trang showed some differences when using 10 digits and 20s to memorize [11], [12], [13].…”

“…Without memory, it is impossible to study and even more impossible to think, so having a fast and good memory is always a major advantage. In recent years, there have been many studies on short-term memory in developed and developing countries [6], [7], [8], [9]. In Vietnam, most of these studies are conducted on elementary, secondary, and high school students [10], [11], [12], [13].…”

Background: Short-term memory is the foundation of long-term memory, which greatly influences cognitive activities, especially in the field of education. Medical students contribute to showing an overview of the characteristics of short-term memory of medical students in particular and students in general in a developing country like Vietnam. Objectives: Surveying the characteristics of visual and auditory short-term memory through numerical data and image data in medical students. Materials and methods: Using a cross-sectional descriptive design method on 160 medical students studying at Can Tho University of Medicine and Pharmacy. The study includes surveys of visual and auditory short-term memory using two types of numerical and image information, using a questionnaire built based on the Nachaive method in the form of online through a website app and collected the results via email. Results: The median results of visual short-term memory (VSTM) in numerical and image data are 11 and 12 respectively. The VSTM figure in numerical data shows that the highest score is 12 (f=46). The VSTM figure in image data records that the score 12 has a dominant frequency (f=87). The median results of auditory short-term memory (ASTM) in numerical and image forms are 10 and 9 respectively. The ASTM figure in numerical data shows that the highest score is 12 (f=32). The ASTM figure in image data notes that score 9 has the highest frequency (f=37). Conclusions: Students of Can Tho University of Medicine and Pharmacy have visual short-term memory that is superior to auditory short-term memory in terms of memorization. The results of visual short-term memory in image data are better than visual short-term memory in numerical data. Conversely, the results of auditory short-term memory in numerical data are better than auditory short-term memory in image data.

“…Some studies have investigated the health effects of RFFs [ 51 - 53 ], dependent on wavelength and frequency ranges [ 48 ]. A higher RFF can penetrate lower to human tissues interact poorly with polar molecules, and its exposure exerts thermal impacts on biological systems [ 54 ].…”

Human is usually exposed to environmental radiation from natural and man-made sources. Therefore, it is important to investigate the effects of exposure to environmental radiation, partly related to understanding and protecting against the risk of exposure to environmental radiation with beneficial and adverse impacts on human life. The rapid development of technologies causes a dramatic enhancement of radiation in the human environment. In this study, we address the biological effects caused by different fractions of non-ionizing electromagnetic irradiation to humans and describe possible approaches for minimizing adverse health effects initiated by radiation. The main focus was on biological mechanisms initiated by irradiation and represented protection, and safety approaches to prevent health disorders.
