Occupational health and safety nowadays is beginning to be seen in a multi-interdisciplinary way. Man's lifestyle also contributes to safety at work and work efficiency. The employee performs tasks at a specific place and time, however, this work is also affected by elements of private life. This paper deals with the impact of private life and lifestyle on human professional work in the areas of work...
The main issue of the article is the corrosion of the reinforced concrete elements by the co-influence of the aggressive and power factors. The problem of corrosion is extremely actual one. Therefore the tests were carried out upon the specimens considering the corrosion in the acid environment, namely 10 % H2SO4. The acid environment H2SO4 was taken as a model of the aggressive environment. Conclusions...
Job satisfaction has a big impact on how an employee performs his job. Both elements have an impact on job safety and employee perception of it. A satisfied employee devotes himself to work, performs orders better, cares for others and for himself. He feels safe in the enterprise. The aim of the paper was to assess employees' job satisfaction and their work performance with use of simply survey. In...
Determination of shear-load-bearing capacity of reinforced concrete beams (according to the current normative documents), comprises particular recommended values, which do not depend on the parameters of the sample or load. This article de-scribes the methodology for determination the shear strength with suggestions for calculation the coefficient CRd,c and compressed element tilt angle Ѳ while reinforced...
The strategy should be designed in such a way as the risk management can operate not only as a system for avoiding losses, but also risk management should allow recognizing and making use of occasions and create new opportunities for the organization. Risk management includes both an evaluation (analytical and evaluation) undertaking as well as planning and control activities aimed at minimizing (reducing)...
In this work on the basis of the developed and tested mathematical model, the numerical experiment is conducted in order to study in more detail the specifics of performance of concrete beams` with combined reinforcement. For this purpose nine series of reinforced concrete beams with different combination of steel bars (A400C, At800, A1000) and ribbon reinforcement (C275) were modeled. In the developed...
In connection with the entry into force of the Anti-terrorism Act, administrators of many production facilities are required to prepare a number of anti-terrorism procedures called anti-terrorist/AT attachment (Security plan related to facilities and equipment subject to mandatory protection in respect of terrorist threats). The article is a case study of the AT attachment implementation in several...
The disability pension system in Poland has operated largely unchanged since the 1970s. A compelling need to reform the system and adjust it to the challenges of the 21st century is an axiom in the Polish social policy. Unfortunately, restructuring of this system has never been, and is not a top priority for the Polish government. Ignoring this problem is a headwind against economic growth in Poland...
One of the important factors on which road safety depends is adequate visibility. This article analyses horizontal visibility within road intersections. The visibility condition depends on many factors, primarily on the geometric parameters of road elements and the location of buildings, fences, vegetation etc., neighboring the road. The aim of the research presented in the study was to determine...
Effective project management requires consideration of aspects such as quality, costs, time, material resources, staff and communication, and risk. In the case of projects co-financed from European Union funds, the main threat is recognition of part or all of the costs as ineligible, which will result in a need to cover them from university's own funds. Therefore, not only successful completion of...
The purpose of the paper is to present the issues of ensuring the safety of machinery and equipment in accordance with the requirements of the Machinery Directive 2006/42/EC of May 17, 2006 on the essential requirements for machines, with regard to the sphere of their import and distribution. This issue is related to the dynamically developing trade in cheaper new machines, mainly from countries outside...
Nodular cast irons are used in a wide range of industrial applications, especially in the automotive industry. SiMo-type of nodular cast iron is suitable for high-temperature applications, for example the exhaust manifolds of the combustion engines; SiCu-type of nodular cast iron is used in various components of tribotechnical units. These automotive components often work in a corrosive environment...
The paper discusses nucleate boiling heat transfer on meshed surfaces during pool boiling of distilled water and ethyl alcohol of very high purity. It presents a correlation for heat flux developed for heaters covered with microstructural coatings made of meshes. The experimental results have been compared with the calculation results performed using the correlation and have been followed by discussion...
The paper presents the analysis of navigation processes used in wells and around-drilling processes. Most common navigation systems used in drilling processes are described. The authors have presented a concept of applying navigation to operations supporting drilling processes, including operations ensuring the safety of drilling staff. Also, they have discussed around-drilling processes which have...
A lot of substances and items are transported by road, sea, rail and air every day. The biggest hazard is created by the transportation of hazardous substances with flammable, caustic or toxic properties. The hazard level increases if such sub-stances are transported through densely populated areas. Traffic intensity, the technical condition of vehicles, drivers’ errors or ignorance and non-compliance...
The paper deals with the working peculiarities of the support zones of reinforced concrete elements subject to bending with due account of the eccentric compression and tension. The authors performed simulation of the stress-strain behaviour of the indicated structures with the aid of “Lira” software which results are shown in the graphical and tabulated form. The performed simulation allowed of tracing...
The operation of various types of machinery and equipment constituting a material work environment exposes employees to many different hazards (especially mechanical hazards). According to the Polish law, the basic duty of both machine manufacturers and employers is to limit the level of these hazards and to provide employees with broadly understood safety. The article presents the basic issues related...
Customers are more and more deciding to use various types of services via Internet. They make very often different types of purchases. E-commerce is becoming more and more popular and developed. Unfortunately, according to customers, online shopping is not free from problems. Customers are afraid that the ordered goods will not be sent to them, will not meet their expectations, or will be destroyed...
The article presents results of research on the information flow between the client and the company, inside the company, and the problems encountered by both parties in the data exchange process. Also included are methods of securing information through unauthorized disclosure, disclosing ideas to other clients. The basis of the study was a survey directed to 75 customers ordering in the examined...
The paper is concerned with the issue of safety and risks in transport with a detailed focus on rail transport. Nowadays, when it is required to prefer safe and environmentally friendly modes of transport, the knowledge of this issue is important. Part of the paper is an analysis of individual risk factors in railway transport. These include risks in the field of railway safety, natural disasters,...
