Chain of events application in workplaces in safety engineering
Authors: Ignac-Nowicka Jolanta 
Published: September 2019

Abstract
The article presents the hazard identification process as a sequence of events that leads to accident and/or material loss at the workplace. The chain of events can be described as an orderly set of circumstances conducive to the emergence of a threat. The article presents an analysis of the application of elements of the events theory to the identification of hazards in an industrial plant on the example of a gas explosion. The circumstances supporting the emergence of a gas explosion hazard were identified by determining the direct and indirect causes of the event and the main conditions leading to the event (loss). Also indicated is the cause of gas explosion hazard, which is the initiating factor in the chain of events.
Hydrogen fuel in transportation
Authors: Machač Jiří , Majer Milan 
Published: September 2019

Abstract
In the time, when the whole world is increasingly engaged in environmental protection, it is necessary to come up with a fuel alternative for transportation, which means generally abandon the use of non-renewable resources (petrol, oil and fossil fuel in general), as they are one of the many factors influencing the emergence of greenhouse gases and the associated global warming. In today's Europe, the pressure is put mainly on automotive companies, to search for sources other than conventional fuels. At present, there is a big boom in the area of electric cars powered from the power network – the vast majority of electric energy, however, is produced in fossil fuel power plants. The second option of possible development in this area is the use of hydrogen as an alternative fuel. This technology, whether it be direct combustion as in diesel or eventually in petrol engines, or energy production in a hydrogen fuel cell, is certainly the way suitable for further development. With hydrogen as a fuel, it is possible to reduce pollutants almost to zero. The article presents a comparison of electricity generated using renewable and non-renewable sources and focuses on a closer understanding of the myth of the dangers connected with using hydrogen as fuel. Furthermore, compares conventional fuels to re-newable hydrogen technologies and focuses on the hydrogen combustion engines together with hydrogen storage and application in transportation.

The analysis of shaft sinking progress as a function of technical and organizational parameters
Authors: Bołoz Łukasz 
Published: September 2019

Abstract
In underground mines, where the deposit is located at considerable depths, mining shafts are key excavations. The project of making the deposit available requires selection of appropriate shaft sinking technology adapted to geological and hydrological conditions and natural hazards. Shafts can be made using the classic drilling and blasting technique or mechanical cutting of the shaft face. Mechanical cutting requires the use of a mining machine, which together with machines for loading and hauling the output and protecting the side walls is a shaft complex. Drilling using mechanized shaft complexes allows for high efficiency and work safety. To improve the efficiency of drilling, it is particularly important to implement many processes in parallel. The article presents an analysis of the progress of shaft sinking with a mechanized complex as a function of technical and organizational parameters. The analysis concerned a new generation cutting shaft complex, developed for the needs of shaft sinking for one of the Polish hard coal mines. The calculations were carried out for a shaft with a maximum diameter of 9.5 m and a total depth of 830 m. The article briefly presents a new solution for the shaft complex. There are presented results of calculations of daily drilling progress and total time of shaft sinking for the developed working technology of this complex. The efficiency of the complex depends on many factors related to technical parameters of individual machines and devices forming the complex and organizational parameters, hence a multi-variant analysis was carried out.

The importance of prediction methods in industry 4.0 on the example of steel industry
Authors: Gajdzik Bożena 
Published: September 2019

Abstract
This paper presents the importance of the prediction of steel production in industry 4.0 along with forecasts for steel production in the world until 2022. In the last two decades, the virtual world has been increasingly entering production. Today’s manufacturing systems are becoming faster and more flexible – easily adaptable to new products. Steel is the basic structural material (base material) for many industrial sectors. Industries such as automotive, mechanical engineering, construction and transport use steel in their production processes. Prediction methods in cyber-physical production systems are gaining in importance. The task of prediction is to reduce risk in the decision-making process. In autonomous manufacturing systems in industry 4.0 the role of prediction is more active than passive. Forecasts have the following functions: warning, reaction, prevention, normative, etc. The growing number of customized solutions in industry 4.0 translates into new challenges in the production process. Manufacturers must respond to individual customer needs more quickly, be able to personalize products while reducing energy and resource costs (saving energy and resources can increase the product competitiveness). The modern market becomes increasingly unpredictable. Production prediction under such conditions should be carried out continuously, which is possible because there is more empirical data and access to data. Information from the ongoing monitoring of the company’s production is directly transferred to the prospective evaluation. In view of the contemporary reciprocal use of automation, data processing, data exchange and manufacturing techniques, there is greater access to external data, e.g. on production in different target markets and with global, international, national, regional coverage. Companies can forecast in real time, and the forecasts obtained give the possibility to quickly change their production. Industry 4.0 (from the business objective point of view) aims to provide companies with concrete economic benefits – primarily by reducing manufacturing costs, standardizing and stabilizing quality, increasing productivity. Industry 4.0 aims to create a given autonomous smart factory system in which machines, factory components and services communicate and cooperate with each other, producing a personalized product. The aim of this paper is to present new challenges in the production processes in relation to steel production, as well as to prepare and present forecasts of (quantitative) steel production of territorial, global and temporary range until 2022, taking into account the applied production technologies (BOF and EAF). For forecasting purposes, classic trend models and adaptive trend models were used. This methodology was used to build separate forecasts for: total steel production, BOF steel and EAF steel. Empirical data is world steel production in 2000-2017 (annual production volume in Mt).

Authors: Palka Dorota , Ciukaj Jolanta 
Published: September 2019

Abstract
The aim of the article is to present the perspective of maintenance development in the context of the 4.0 industry concept. One of the factors that determine the safe and effective use of machines and devices is the properly maintained maintenance process. Correct performance of activities as part of this process requires the use of appropriate knowledge and experience from people implementing this process. Very important in this process is, above all, good organization of work and technical knowledge. The very rapid development of technology causes that teams dealing with the maintenance of traffic in enterprises must systematically acquire knowledge and optimize their activities. Effective exploitation of all types of devices is a set of rules, rules, procedures and actions, the main aspect of which is a human being. Knowledge resources should have appropriate substantive content adapted to the recipient. The article presents a modern solution supporting the maintenance process, taking into account the tools supporting the activities of human teams. The basic principles of maintenance in the enterprise covering machine monitoring systems, production management and management of information on the state of the machine park are discussed. There are also examples of the use of selected tools in the mining industry. Reference was also made to the prospects and directions of the development of maintenance in relation to the fourth industrial revolution.

Authors: Kotus Martin , Drlička Róbert , Mikuš Rastislav , Žarnovský Jozef 
Published: September 2019

Abstract
The paper deals with the issue of occupational health and safety in a metalworking manufacturing organization. Hazard and threat have been defined when cutting metal materials with a band saw. We assessed the risk by an extended point method, where we determined the risk rate values. In most cases of sawmill work, we found a “moderate” or “negligible” risk. The highest, ‘serious’ risk we found in a possible electric shock. In this case, we have also taken the necessary actions. As a precaution, we have also proposed safety measures for other threats.

Published: September 2019

Abstract
The sales market requires both the highest quality of offered goods and satisfactory prices for the buyer. In addition to the reliability of the important aspects are also the time of order fulfillment, reliability, readiness to act around the clock, and service of sold goods after their sale. In the production and confection of conveyor belts, the priority is a customer who, having strictly defined product requirements, also has individually focused goals. To meet these aspects, you need to look after the product both during its production and after. The products of this industry are specific, so that they can be used, after sales service is often required to be installed at the customer and possible actions to maintain their good condition during operation. The article analyzes selected production processes of transmission belts to identify disturbances. The analysis uses the value stream mapping method. Then, improvement methods were proposed.
Hierarchical EPC models – review of model linking concepts
Authors: Szczęśniak Bartosz 
Published: September 2019

Abstract
EPC models are currently among the leading standard business process modelling solutions. As long as the rules for creating flat EPC models are explicit and raise no significant doubts, when it comes to linking models of different types, the literature of the subject delivers diversified solutions. Four such alternative concepts that can be applied in this respect have been identified and described in this article. They have been used to link EPC models for four cases proposed. These cases differ as to the degree of complexity, and they represent different kinds of potential links between processes being modelled. Using the concepts in question with reference to the cases defined has made it possible to identify situations in which it is impossible to link models, or when it raises certain doubts. What has also been proposed is that one of the concepts identified in the paper can be modified in such a manner that using it to link EPC models does not pose any problem in any of the cases discussed.

Authors: Maryniak Anna 
Published: September 2019

Abstract
A constant growth of interest in GSCM on the part of business practitioners creates a need to develop research within this field. One of the basic questions is why, despite numerous evidence of benefits resulting from the use of pro-environmental practices in supply chains, the level of GSCM implementations is low. Therefore, the aim of the paper is determining which barriers constitute the greatest obstacles on the way of GSCM implementation. The studies were conducted among Polish market entities. Therefore, they were prepared in the part of Europe in which there are not many studies regarding this topic. As a result of the conducted studies, it was determined that the greatest barriers for pro-environmental practices are included in the field which concerns knowledge and cost. What is more, the importance of particular barriers was specified in the paper.

Abstract
Neonatal respiratory distress syndrome (NRDS) is a consequence of immaturity at birth and it is still associated with relatively high mortality rate. The aim of this study was to identify the factors associated with the occurrence of fatal outcome in newborns with neonatal respiratory distress syndrome.The research was designed as a case-control study nested in a retrospective cohort, and it enrolled newborns treated during 2015 at Pediatric Clinic of Clinical Center in Kragujevac. Diagnosis of NRDS and decision about the treatment were left at the discretion of attending pediatricians. The cases were patients with fatal outcome, while controls were randomly selected from the pool of survivors and matched with each case by gender in a ratio of 4:1. The study included 371 newborns, of whom 201 (54.2%) were male and 170 (45.8%) female. Lethal outcome occurred in 36 newborns (9,7%). Significant association was found between death and APGAR score (ORadjusted: 0.516, 95% CI: 0.322-0.827), weight on delivery (ORadjusted: 0.996, 95% CI: 0.993-0.999), duration of hospitalization (ORadjusted: 0.901, 95% CI: 0.835-0.972) and mechanical ventilation (ORadjusted: 165.256, 95% CI: 7.616-3585.714). Higher gestational age, higher birth weight, higher APGAR score and longer duration of hospitalization were singled out as protective factors, while use of mechanical ventilation increased the risk of death. Major limitations of the study were retrospective nature and relatively small number of identified cases. Postponing delivery and delivery in institution with neonatal intensive care unit are crucial for survival of newborns with NRDS.

Published: September 2019

Abstract
Falls and fall-related injuries during hospitalization may cause serious problems and consequences for patients, their quality of life as well as increased healthcare expenses. The aim of the paper were to assess fall risks and identify risk factors, related to falls among stroke patients. This was a retrospective cohort study that included 217 neurological patients with acute stroke who have experienced fall during hospitalization. Morse Fall Scale was used to estimate a likelihood of falling for hospitalized patients. In total, 1.4% patients with acute stroke experienced a fall during hospitalization. According to the fall risk assessment, 77% of the patients presented a high risk for falls. Women, older respondents and those who were hospitalized for period longer than 22 days and who had higher levels of care, had higher values of Morse score. The most common risk factors for falls are: the presence of other medical diagnosis, the use of disability aids while walking, the use of intravenous therapy, disorientation in time and space, and the largest contribution to Morse score comes from using disability aids while walking and transferring patients. Greater risk of falling was observed in older neurological patients with ischemic type of stroke and weakness on the left side of the body, patients with longer hospitalization period and those with higher level of care.
