Background: In December of 2019, SARS-CoV-2, a new type of coronavirus, appeared, and it turned into an international epidemic. The consequences of the pandemic, especially the isolation measures, fear of infection and bad economic trends, as a result of the crisis, threaten people's basic psychological needs. Objective: The objective of this research was to assess the impact of the COVID-19 pandemic on mental health and perceived social support of persons with disabilities in Bosnia and Herzegovina. Methods: The research included a total sample of 232 respondents with different types of disabilities. The Symptom Checklist (SCL-90) was used to verify the research objective, which assessed three dimensions: somatization, depression and anxiety. Also, in order to verify the research objective, the Multidimensional Scale of Perceived Social Support was applied, which consists of 12 statements that measure the perceived social support of family, friends and other people. The research data was processed with descriptive and inferential statistics. The basic statistical parameters were calculated, while the t-test was used for an independent sample of respondents to verify the set objective. Results: The results of the research showed that persons with disabilities, who were infected with the SARS-Cov-2 virus, had a significantly higher level of somatization, anxiety and depression compared to those who were not infected with the virus. The results in relation to social support did not prove to be statistically significant. Conclusion: The obtained results lead to the conclusion that, in the future, interventions by experts of various profiles must be planned to preserve the mental health of persons with disabilities, which is why it is important to invest in the emotional, psychological, social, physical and spiritual well-being of the individual.

Robots are commonly envisioned as assisting older adults in physical tasks or providing companionship. But there has been less focus on helping older adults achieve more intangible, but equally important, aspects of wellness, such as a feeling of purpose and meaning in life. Here, we share our experiences working and learning together with older adults on developing a robot that can support their achievement of ikigai---meaning or purpose in life.

Abstract It is known that aquatic macrophytes are an important part of freshwater ecosystems, and that they play a different role in their structure and functioning. Their presence and distribution depends on water temperature and transparency, nutrient content, conductivity, pH, chemical composition and water circulation. Therefore, the goal of our research was to determine the influence and interrelationship of physicochemical parameters of water on the content of photosynthetic pigments in aquatic macrophytes of Lake Necik, in the Ramsar area of Bardača (Republic of Srpska). Content of total chlorophyll (a + b) during the growing season (June–October) ranged from 0.231 to 1.145 mg g−1 FW in Phragmites communis Trin. ex Steud., from 0.061 to 0.541 mg g−1 FW in Salvinia natans L. (All.), from 0.063 to 0.626 mg g−1 FW in Utricularia vulgaris L. and from 0.063 to 0.443 mg g−1 FW in Ceratophyllum demersum L. Research has shown that floating and submerged macrophytes have a lower ratio of chlorophyll a/b compared to emergent hydrophytes, which is most likely the result of stress caused by increased light intensity and temperature. Seasonal variations in the content of photosynthetic pigments indicated that the species Phragmites communis proved to be more tolerant to the stress caused by the influence of various abiotic factors, while Salvinia natans proved to be more sensitive. Spearmon’s correlation coefficient of the physicochemical parameters of water and the concentration of photosynthetic pigments of macrophytes showed a significant influence of certain abiotic factors (temperature, transparency and nutrients) on the content of pigments in the leaves of Phragmites communis, Salvinia natans, Utricularia vulgaris and Ceratophyllum demersum L.

Advancements in neurosurgical visualization have been made possible by the introduction of the operating microscope (OM) and the emergence of exoscopic technology (EX). Both OMs and EXs provide enhanced magnification and illumination, but they come with their own set of advantages and disadvantages. OMs provide high-quality magnification and illumination and have been used successfully in a variety of surgical procedures. They can be customized to fit the specific needs of the surgeon and are a well-established technology. However, they can be bulky, expensive, and cause discomfort during extended procedures. EXs provide high-definition magnification and illumination, improved depth perception and ergonomics, and can be cost-effective. They can be customized to fit the specific needs of the surgeon and can be made using locally available materials, reducing the need for expensive imports. However, they may require adjustment and have a learning curve for surgeons who are used to operating with OMs. Additionally, they may have limited availability in some healthcare settings. The choice between OMs and EXs will depend on the specific needs of the surgeon and the healthcare setting. The integration of 3D EX systems has revolutionized neurosurgery, offering improved depth perception and ergonomics. EX's cost-effectiveness addresses accessibility concerns, making it an attractive alternative, particularly for low and middle-income healthcare settings. The exoscope seems to be a safe alternative compared to an operative microscope for the most common brain and spinal procedures. The exoscope may help expand access to neurosurgical care and training worldwide. In conclusion, both technologies have their own set of advantages and disadvantages, and the choice between them will depend on the specific needs of the surgeon and the healthcare setting.

Next-generation mobile communication systems are planned to support millimeter Wave (mmWave) transmission in scenarios with high-mobility, such as in private industrial networks. To cope with propagation environments with unprecedented challenges, data-driven methodologies such as Machine Learning (ML) are expected to act as a fundamental tool for decision support in future mobile systems. However, high-quality measurement datasets need to be made available to the research community in order to develop and benchmark ML-based methodologies for next-generation wireless networks. We present a reliable testbed for collecting channel measurements at sub-6 GHz and mmWave frequencies. Further, we describe a rich dataset collected using the presented testbed. Our public dataset enables the development and testing of innovative ML-based channel simulators for both sub-6GHz and mmWave bands on real-world data. We conclude this paper by discussing promising experimental results on two illustrative ML tasks leveraging on our dataset, namely, channel impulse response forecasting and synthetic channel transfer function generation, upon which we propose future exploratory research directions. The original dataset employed in this work is available on IEEE DataPort (https://dx.doi.org/10.21227/3tpp-j394), and the code utilized in our numerical experiments is publicly accessible via CodeOcean (https://codeocean.com/capsule/9619772/tree).

Microbial biofilms are organized consortiums of microorganisms in the self-produced matrix, characterized by increased resistance to antimicrobial agents. Candida albicans belongs to the regular human microbiota, but it could be highly pathogenic. Essential oils (EOs) are widely distributed secondary metabolites, proven for various biological activities. The main goal of this investigation was to evaluate the antifungal and antibiofilm properties of EOs from Citrus limon (L.) Osbeck, C. reticulata Blanco, Nigella sativa L., and Foeniculum vulgare Mill. against C. albicans. Antifungal activity was evaluated through the disk diffusion method, followed by the determination of the minimum inhibitory (MIC) and minimum fungicidal concentration (MFC). Antibiofilm assays were implemented through the tissue culture plate method and determination of the biofilm inhibition. Zones of inhibition were detectable for all tested EOs, with the greatest activity of N. sativa (28.30±1.50 mm to 39.30±1.10 mm). MIC values ranged from 62.50 μg/ml (N. sativa) to 125 μg/ml (C. limon), and 250 μg/ml (C. reticulata and F. vulgare). All tested EOs performed an impact on the biofilm-forming capacity of tested yeast. The antibiofilm activity was species-specific and concentration-dependent. The highest antibiofilm activity was recorded for F. vulgare. Obtained results suggest that investigated EOs possess antifungal and antibiofilm potential.
