Opis:
In comparison, railways are the safest mode of land transport, not only regarding pure safety performance indicators but also considering external costs to society and to a member state. As for Polish railways, the year 2016 was the safest since 2008 even despite the growth of the railway market. There are still elements that need to be taken care of, such as continuous improvement of safety culture so that there can be a consistency in safety statistics, and improvement of total safety performance. The other key aspect is the analysis of human factor with the involvement of professionals in the area of human performance since it seems that current activities are insufficient. Authors would like to summarise this short article regarding railway safety performance by saying that undoubtedly, railways are constantly the mass transport mode to choose regarding the safety of travel.

Opis:
Alongside the increase in air traffic and number of aircraft, the number of reported aviation events has also been increasing. We processed the data included in the European Coordination Centre for Aviation Incident Reporting Systems (RCCAIRS), analyzing small and large aircraft reliability and the safety of their operations, covering events according to ICAO aviation occurrence categories. Airframe systems are the largest contributor to the total number of reported events which occurred in Polish registered aircraft in the years 2008-2020. A detailed study of airframe systems reliability was carried out in order to assess the real reason for the failures. Airframe systems faults were assigned to specific ATA chapters and then to each of their sections. The results of this analysis may support the decisions of supervisory authorities in the areas where security threats are most important. They can also help aircraft operators with identification of the airframe units which require special attention. Identification of significant parts due to the frequency of malfunctions of particular system components may support designers. In short, these results are valuable in terms of further developments in statistical tools facilitating New Product Introduction (NPI).

Opis:
This paper attempts to replicate a safety climate model originally tested in Australia to assess its applicability in a different context: namely, across production workers in 22 medium-sized metal processing organizations in Austria. The model postulates that safety knowledge and safety motivation mediate the relation between safety climate on the one hand and safety compliance and participation on the other. Self-report data from 1075 employees were analyzed using structural equation modeling (SEM). The results of the replication study largely confirmed the original safety climate model. However, in addition to indirect effects, direct links between safety climate and actual safety behavior were found.

Opis:
As in every industry at risk, the human and organizational factors constitute the main stakes for maritime safety. Furthermore, several events at sea have been used to develop appropriate risk models. The investigation on maritime accidents is, nowadays, a very important tool to identify the problems related to human factor and can support accident prevention and the improvement of maritime safety. Part of this investigation should in future also be near misses. Operation of ships is full of regulations, instructions and guidelines also addressing human factors and safety culture to enhance safety. However, even though the roots of a safety culture have been established, there are still serious barriers to the breakthrough of the safety management. One of the most common deficiencies in the case of maritime transport is the respective monitoring and documentation usually lacking of adequacy and excellence. Nonetheless, the maritime area can be exemplified from other industries where activities are ongoing to foster and enhance safety culture.

Opis:
The introduction of anions and cations into energetic materials can significantly improve their physicochemical and energetic properties. The K, Zn, Ba, Cu and Pb salts of 1,1,2,2-tetranitraminoethane (TNAE) were synthesized using TNAE as the starting material, and were characterized by IR spectroscopy, NMR spectroscopy and elemental analysis. All of the energetic salts exhibited relatively high thermal stabilities (decomposition temperatures ranging from 195.1 °C to 279.3 °C) and high densities (ranging from 2.1 g·cm–3 to 3.7 g·cm–3). It was demonstrated that the introduction of metal ions conveys better thermal stability than covalent TNAE itself. More importantly, the Zn, Ba and Cu salts exhibited good thermal stability, high density, low sensitivity, and therefore have the potential to be a new class of insensitive, highly energetic explosives for practical applications.

Opis:
The construction industry in India is the second most important contributor to its gross domestic product. However, high rate of accidents and fatalities have tarnished the image of industry in India. Although the industry contributes significantly to the Indian economy, safety management is the primary concern alongside with frequent workplace accidents. The role of safety management is vital to improve safety performance of an organization. The functions of safety management include planning, organizing, staffing, directing, controlling and coordinating safety activities with an aim to minimize accidents/injuries. Safety trainings, employee participation, compliance of safety procedures and motivational schemes are part of safety management which influences the overall safety performance. Several metrics were developed to measure the safety performance of an organization but not a single measure will reflect the overall performance. The present study considered parameters pertaining to the safety management which have influence on the safety performance of a construction organization in India. The parameters are analyzed by formulating a goal programming model. The results of the study suggests that much improvement is needed in the area of safety trainings and the revised targets were established.

Opis:
Safety performance index is a tool with the potential to grasp the intangible domain of aviation safety, based on quantification of meaningful aviation safety system properties. The tool itself was developed in the form of Aerospace Performance Factor and is already available for the aviation industry. However, the tool turned out to be rather unsuccessful as its potential was not fully recognised by the industry. This paper introduces performed analysis on the potential and it outlines new features, utilising time-series analysis, which can improve both the recognition of the index by the industry as well as the motivations to further research and develop methodologies to evaluate overall aviation safety performance using its quantified system properties. This paper discusses not only the features but also their embedding into the existing approach for the development of aviation safety, highlighting possible deficiencies to overcome and relating the scientific work already performed in the domain. Various types of appropriate time-series methodologies are addressed and key specifications of their use with respect to the discussed issue concerning safety performance index are stated.

Opis:
The use of roundabouts is well recognized for sustaining an efficient and safe intersection. However, the safety results may vary based on the prevailing conditions. Therefore, this study assesses the safety performance of roundabouts in Jordan. This study developed a predictive model by collecting and analyzing all accident records of 12 major urban roundabouts in the country over 3 years. For developing the model, this study employed an accident frequency analysis. The model calculated the rate of accidents and incorporated the geometric and operational characteristics of roundabouts. This was followed by ranking the safety performance of the roundabouts. It was concluded that driver behavior of violating the traffic rules, lack of clear lane markings in the circulating area and inadequate signage at the roundabouts entries are the main causes of roundabout accidents. The research recommends including the developed predictive model in future traffic control and planning studies, for identifying hazardous locations, or for prioritizing roundabout improvements based on safety performance.

In a context of increasing pressure on performance, which affects almost all Algerian companies, question effectiveness of a policy of well-being at work depends on its impact on organizational performance: Numerous figures show costs of psychosocial risks, stress, absenteeism, etc. By virtue of the principle that a happy worker would also be a more productive worker, generating benefit for enterprise and a cost-reducing factor, even generating a better productive and commercial performance. Therefore, to reach these expectations, health culture and well-being at work must be part of basic values of actors of work world who are responsible for implementing an integrated preventive approach in all companies. As a result, an appeal is made to all managers and partners to make a joint commitment to effectively and efficiently reduce causes of work accidents and occupational diseases proliferation: company health, it’s health in the business. From now on, occupational health capital management and wellbeing of any company is one of its military priorities for its performance. It is part of company strategic objectives and must be taken into account in its daily operation.

This work introduces important properties of some new derivatives of nitrotetrazolyl-imidazole as high nitrogen energetic compounds, which are evaluated and discussed using some reliable models. The predicted properties are also compared with 1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane (HMX). It is shown that some of these compounds can be seen as interesting organic explosives with relatively high performance and low sensitivity, which could be used for important industrial applications. Since some of the new compounds have a relatively good oxygen balance, the calculated specific impulses confirm that these compounds can be considered as suitable oxidizers in solid propellants.

Guarantee of the ship safety is the primary task posed for modern navigation systems. This concerns monitoring the proper ship position as well as providing accurate information about the collision threat. The proper interpretation of this information belongs to the navigator. He must take into account many variables affecting the assessment of the situation and then make the right decision regarding anti-collision manoeuvres. This assessment could be made easier for him with use some form of graphic target data presentation methods other than currently required and described in IMO performance standards. Other possible graphic presentation methods of collision information are described in the article along with the concept of their usage.
Podstawowym zadaniem stawianym przed nowoczesnymi systemami nawigacyjnymi jest zapewnienie bezpieczeństwa statku. Dotyczy to zarówno konieczności właściwej kontroli pozycji statku jak i dostarczenia rzetelnej informacji o zagrożeniu kolizyjnym. Właściwa interpretacja tej informacji należy do nawigatora. Musi on uwzględnić wiele zmiennych czynników mających wpływ na ocenę sytuacji, a następnie podjąć właściwą decyzję odnośnie podejmowanych manewrów antykolizyjnych. Możliwość zastosowania innej formy graficznej prezentacji informacji niż wymagana obecnie przez przepisy może ułatwić mu taka ocenę. W artykule przedstawione zostały inne sposoby graficznej prezentacji informacji kolizyjnej wraz z koncepcją ich wykorzystania.

Opis:
The reports of committees investigating the causes of rail accidents indicate the significance of the so-called human factor (e.g. UTK, 2019). In addition to issues related to perso nality functioning, the organization and culture of work, this also includes variables related to the cognitive functioning of train drivers themselves. These are significant factors that determine the occurrence of accidents that result from ignoring or not spotting railway signals and signs. The purpose of this study was to verify the relationship between cognitive functioning and safety determinants, which was measured using an eye-tracking technique. The application of this technique was intended to check its usefulness in the field of railway traffic safety and to achieve an approximate simulation environment of the real working conditions of a train driver. In the present study, the Vienna Test System was used as a me - thod for the determination of cognitive functioning. Based on the variables described in the subject literature, the following tests were applied: Determination Test, Visual Memory Test, Visual Pursuit Test, Reaction Time, Cognitrone, Signal Detection and Vigilance. In addition to computer cognitive tests, an eye-tracking test method was designed based on a film recorded in real train-driving situation. Measures describing areas of interest (AOI) that are crucial for safety were analysed. Due to the pilot nature of the research, only 10 passenger train drivers participated in the study. The results of the study showed a link between the cognitive functioning of the train drivers and visual security determinants. Significant correlations were found with stress tolerance resulting from cognitive overload, visual memory, alertness and concentration ability under time pressure. The study confirmed the significant role of the train driver's cogni- tive functioning in the analysis and perception of safety-critical signals. The use of an eye-tracking method has delivered results that are in agreement with studies based on other methods. This pro- vides a sound basis for the continuation of research using eye- tracking in the assessment of rail transport safety. In the future, the research should be extended to include an analysis of the effect of demographic and situational variables (types of signalling devices and signage) and a broader model of the relationship between cog- nitive functioning and the driver's visual attention. This will provide data that is crucial for the prevention of railway incidents and the development of training plans for train drivers.

The present age is marked by an unsustainable trends not only in the field of production but also in consumption, and concerns all levels of the community. At enterprise level, there is an effort to eliminate these negative trends by the application of several concepts in which environment and security are the essential parts. The paper focuses on environmental management as a significant part of the corporate sustainability concept and reports using of specific environmental tools to promote corporate sustainability. Apart from the tools, the paper also deals with motives that lead enterprises to focus on the environmental protection. The data were obtained through a questionnaire survey among Slovak manufacture enterprises. The focus of the research is transformed into several hypotheses. Several methods of inferential statistics (Interval estimate, Chi-square test, Kruskal-Wallis ANOVA, and Wilcoxon signed-rank test) were used to verify our hypotheses. In hypothesis testing we used .05 level of significance. Based on the descriptive statistics it is evident that 50% of the total number of enterprises (N = 336) use at least one of the environmental management tools. Their using depends on the origin of capital. The results also indicate the individual benefits of focusing on environmental management and underline their importance to the business world.

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 order to achieve this aim, a survey was conducted among employees of a chosen metallurgical enterprise who were asked to assess level of their job satisfaction. The employees defined their job satisfaction by referring to 20 statements describing this satisfaction and evaluating three factors that were used to compute the satisfaction index. The survey allowed for indication the general level of employee satisfaction.
