    Panic over coronavirus has led to many non-medical advice in social media on how to boost the immune system to avoid getting sick. There is currently no proven scientific evidence supporting use of a specific natural food or supplement to improve the human immune system or prevent SARS-CoV-2 infection. However, there are many effective behaviours, nutritional and training strategies that can reduce exposure to pathogens and limit immunosuppression and thus reduce the risk of disease. This study provides information on the most relevant factors that affect the immune system in the scientific literature.



    Acoustic climate management in medical facilities – recommendations
    dr hab. inż. Dariusz Pleban , prof. CIOP-PIB , dr inż. Bożena Smagowska , dr inż. Jan Radosz

    The results of noise measurements that were carried out in selected hospital rooms are characterised in the paper. The results of the assessment of working conditions in medical facilities due to noise are also discussed. This assessment was based on survey results of more than 300 doctors, nurses and diagnostic laboratory staff. The results of noise measurements and surveys formed the basis for the elaboration of general recommendations for acoustic climate management in operating rooms, treatment rooms, medical diagnostic laboratories, intensive care units, nurses' rooms and hospital corridors.



    Assessment of the quality of the performance of ambidextrous coordination tasks in the context of gender and age
    prof. dr hab. inż. Danuta Roman-Liu , mgr Zofia Mockałło

    The article presents the results of the quality analysis of performing bimanual coordination tasks. The study was conducted on four groups differentiated by gender and age (20-30 years and 60-67 years). The subjects performed two-hand coordination tasks developed at CIOP-PIB and tests included in the Vienna Test System. The results show significant differences in the values of control quality indicators between the group of younger people and the group of older people. Stronger differentiation was observed in the bimanual coordination tasks. There are stronger differences in terms of age than of gender.



    A comparison of solutions of the systems warning persons using hearing protectors against approaching vehicles

    In addition to the most commonly observed effects of hearing loss in employees, noise in the work environment also masks sounds that are useful in the workplace. Another factor associated with the occurrence of noise that also makes it difficult to perceive useful sounds is the use of hearing protectors. It is therefore important to provide workers who use hearing protectors with an additional opportunity to perceive information about risks such as those associated with approaching vehicles. The article presents the work on solutions that are the basis for the development of a system to warn workers who use hearing protectors against collision with a vehicle. This work consisted in selecting and testing solutions that could potentially be used in this system. The first solution analyzed was a system that allows the reading of the received signal strength indicator (RSSI) value indicating the power of the received radio signal and built, based on a Bluetooth class 2 device. Unfortunately, the distance for which the RSSI value changes in a way that is possible to use in the system is limited to a few meters. Another solution analyzed was the system operating on the principle of detecting the presence of the transmitter in the area around the employee. The tests showed that it is possible to detect the signal, in the open space, at speeds not greater than about 3 km/h. The third analyzed solution was a system in which the transmitter was built on the basis of Bluetooth class 1 device, providing greater power of radio signal. The tests indicated the possibility of correct assessment of the distance between the vehicle and the employee within the required range of distance. Therefore, it was decided that this solution will be further developed.
