AbstractCarbon dioxide (CO2) may have toxic effects at concentrations much lower than the concentration at which its stifling effect of asphyxiant is reflected. In the workplace, the maximum permissible exposure limit of 5000 ppm is permitted on the average. However, there are certain places where the concentration of CO2 in an enclosed room or area may potentially reach extreme and life-threatening levels. Extreme levels of CO2 may lead to death, especially in enclosed spaces, such as in fermentation rooms or in the process of wine production or in breweries. CO2 may have negative effects on health and safety at the workplace. Monitoring and control of CO2 in the working environment is important for the safety and health of employees and is one of the approaches to a healthier environment in the workplace. The use of CO2 sensors to control the ventilation can be an effective measure.

As the criticality of e-mail for electronic business activity increases, adhoc e-mail implementation, prolonged management neglect and user abuse of e-mail systems have generated negative effects. However, management’s ability to rectify problems with e-mail systems is hindered by our understanding of its organisational use. Research on e-mail systems is often dated and based on quantitative methodologies that cannot explain the interaction between various controls in organisational settings. Updating our understanding of the organisational aspects of e-mail systems utilizing qualitative methods is necessary. This chapter presents a multiple case study investigation of e-mail system monitoring and control. The study examines the interaction between key elements of e-mail control identified by previous researchers and considers the role of such controls at various implementation phases. The findings reveal eight major elements to be particularly important in monitoring and controlling e-mail systems within the organisations studied. These are: (1) form a cross-functional e-mail system management team; (2) implement and regularly update e-mail management software; (3) formulate a detailed and legally sound e-mail policy; (4) engage in structured e-mail system training; (5) create and maintain ongoing awareness of e-mail policy; (6) engage in a process of hybrid feedback and control-based e-mail monitoring; (7) firmly enforce discipline in accordance with the e-mail policy; and (8) conduct regular reviews and updates of the e-mail management programme.

For the individual and for society, human life and health are great values, which are often particularly difficult or impossible to measure, though they are irreplaceable values. Even in the oldest historical stages of the development and life of society, many important doctors and scientists were interested in the social aspects of health care, e.g. Hippocrates, Aristotle, Avicenna. Paracelsus († 1541, Swiss philosopher and physician) and Georgius Agricola († 1555, German chemist and mineralogist). Based on their own experience gained from daily contact with workers and their working environment, they examined disorders caused by the harmful factors of the working environment and working processes. The ever-changing world of work increasingly brings new risks into working processes, which are directly related to the work performed by employees. As part of the EU-OSHA (European Agency for Safety and Health at Work) strategy to increase health and safety at work, the European Risk Observatory called on EU Member States to improve the detection of these risks in the working environment. Considering the above, the authors of this article have set themselves the goal of mapping the current situation in the area of the creation, protection and quality management of the working environment. They describe general requirements for protecting occupational health and safety, mainly in Slovakia. They are convinced that current developments present the need to know as much as possible about the living and working environments, to have a thorough knowledge of working conditions and all the factors that affect the health of employees, to know and choose assessment procedures to reduce the negative effects of these factors to a minimum. It is important that we keep in mind that healthy working conditions are among the most valuable assets of individuals, communities and nations.

Forest ecosystems in Serbia suffer great damages each year due to the negative effects of water, wind and fires, which are caused by climate change. In this sense, the aim of the research is to determine the degree of threat from the effects of water, wind and fires for selected forest regions, as well as to form ranks and groups of forest regions, and their threat indexes. Through cluster analysis method, forest regions are grouped based on two criteria (number of damage and damaged area), in order to calculate their threat index. In this way, three groups of forest regions were identified: considerably, moderately, and slightly threatened. Rasinsko and Tarsko forest region (IUP=6) have the highest threat index in relation to the affected area. Sumadijsko, Juznokucajsko, Gornjeibarsko, Timocko, Toplicko and Nisko, with IUP=3 belong to the group of slightly threatened areas. The results of these studies can be used for achieving better quality of monitoring and control), prevention and response, should any harmful event occur.

ABSTRACT Enterococcus faecalis, a common cause of endocarditis and known for its capacity to transfer antibiotic resistance to other pathogens, has recently emerged as an important, multidrug-resistant nosocomial pathogen. However, knowledge of its lineages and the potential of particular clones of this species to disseminate and cause disease is limited. Using a nine-gene multilocus sequence typing (MLST) scheme, we identified an evolving and widespread clonal complex of E. faecalis that has caused outbreaks and life-threatening infections. Moreover, this unusual clonal complex was found to contain isolates of unexpected relatedness, including the first known U.S. vancomycin-resistant enterococcus (E. faecalis strain V583), the first known penicillinase-producing (Bla+) E. faecalis isolate, and the previously described widespread clone of penicillinase producers, a trait found in <0.1% of E. faecalis isolates. All members of this clonal cluster (designated as BVE for Bla+ Vanr endocarditis) were found to contain a previously described putative pathogenicity island (PAI). Further analysis of this PAI demonstrated its dissemination worldwide, albeit with considerable variability, confirmed its association with clinical isolates, and found a common insertion site in different clonal lineages. PAI deletions, MLST, and the uncommon resistances were used to predict the evolution of the BVE clonal cluster. The finding of a virulent and highly successful clonal complex of E. faecalis with different members resistant to the primary therapies of choice, ampicillin and vancomycin, has important implications for the evolution of virulence and successful lineages and for public health monitoring and control.

Personal computers (PCs) are a powerful resource in the EM Laboratory, both as a means of automating the monitoring and control of microscopes, and as a tool for quantifying the interpretation of data. Not only is a PC more versatile than a piece of dedicated data logging equipment, but it is also substantially cheaper. In this tutorial the practical principles of using a PC for these types of activities will be discussed.The PC can form the basis of a system to measure, display, record and store the many parameters which characterize the operational conditions of the EM. In this mode it is operating as a data logger. The necessary first step is to find a suitable source from which to measure each of the items of interest. It is usually possible to do this without having to make permanent corrections or modifications to the EM.
