Noise is omnipresent in biomedical systems and signals. Conventional views assume that its presence is detrimental to systems’ performance and accuracy. Hence, various analytic approaches and instrumentation have been designed to remove noise. On the contrary, recent contributions have shown that noise can play a beneficial role in biomedical systems. The results of this literature review indicate that noise is an essential part of biomedical systems and often plays a fundamental role in the performance of these systems. Furthermore, in preliminary work, noise has demonstrated therapeutic potential to alleviate the effects of various diseases. Further research into the role of noise and its applications in medicine is likely to lead to novel approaches to the treatment of diseases and prevention of disability.

By coal mining and exploatation, radioactive radon gas, which is captured in natural geological structures, is reallocated from the deep coal layers. Hence it is concentrated in the depots and coal seams of the mines or being transported to the surface of the earth where it can significantly change the levels of radioactivity in the working premises and residences. This paper presents the results of a three-year research of radon activity concentration in the air in hole and surface coal mines of Bosnia and Herzegovina. Detected concentrations of radon in the coal gaseous structure, atmosphere and other ambient media are in correlation with the properties of geological structures, technology for obtaining coal and meteo-climatic changes. They were measured with Alpha GUARD PQ 2000 radon portable measuring system (instruments Genitron-Frankfurt) and RadoMeter 2000 (Radosys LTD. Budapest), using the SS-NTD method.

While conventional similar books focus on medical science and social aspects, this book emphasizes computing science and engineering design. This feature can help with both industry development and academic research. It book explains in detail both entire telehealthcare engineering system and individual hardware components. For example, it has circuit design details on ECG /EEG sensors. Highlighting basic principles and deep research development (R&D) details, the book focuses on two important design aspects: medical sensor design and medical signal processing. Their principles can be directly used for practical product design.

Public telephones are handled by many people and can serve as vehicle of disease transmission. Our study involved the microbiological analysis of public telephones. We analysed 60 telephones from the downtown area of Sarajevo and they were all positive for bacterial contamination. The analysis used microbiological, biochemical and serological methods. More Gram-positive than Gram-negative bacteria were isolated, and the most common bacteria were Staphylococcus epidermidis. Beside this, we also found pathogenic and opportunistic bacteria such as Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa. The hygiene of the environmental surfaces and public objects is to be considered as various opportunistic bacterial pathogens were isolated.
