Design stability standards were ultimately adopted by IMO quite recently. The designers and operators of ships are, however, aware that the standards do not constitute an ultimate solution. At present much attention is devoted to the operational aspects of stability because it is well known that 70 to 80 % of casualties are caused by human unreability. The author considers operational aspects of stability including human factor and discusses several methods necessary to deal with the situation in order to safeguard safe ship operation in various weather conditions.

Safety is one of the basic human needs. In the occupational context, safety determines the quality of one’s work. Social service workers are one of the professions that provide social services to diversified groups of the system’s users. This involves various risks and threats to safety. System determinants include five main factors: security policy, legal system, financial and material security, work organization and technological support, and professional stability. Each of the factors is equally essential in creating the culture of social workers’ safety.

The quality of being able to operate safely (S, in Polish - bezpieczność) and the quality of being hazard-prone (Z, in Polish – zagrożeniowość, zagrażalność), Z being the opposite of S, are important properties of any maritime vessel and/or aircraft, i.e. any engineering system/device (UT). The rates WS and WZ considered in terms of probability and remaining within the [0, 1] interval are measures of these properties. High value of WS enables the engineering system/device (UT) to be operated with the possibly maximum safety. The sum of WS and WZ is one (unity), whereas the product thereof satisfies the following condition: WS x WZ ≤ 1. The derived equation of indeterminacy points out to the fact that any increase in the value of WS by subsequent increments ΔWS, which makes the WS approach the limit of unity, demands ever greater amount of power and abilities, i.e. energy (expenses).

PL

Bezpieczność (S) i zagrożeniowość (Z) – jako przeciwieństwo bezpieczności – są ważnymi właściwościami statku morskiego, statku powietrznego – każdego urządzenia technicznego (UT). Ich miarami są wskaźniki WS i WZ rozważane w kategorii prawdopodobieństwa zawierają się w przedziale [0,1]. Wysoka wartość WS umożliwia użytkowanie UT z możliwie największym bezpieczeństwem. Suma WS i WZ wynosi jeden, a iloczyn spełnia warunek: WS × WZ ≤ 1. Wyprowadzone eksploatacyjne równanie nieoznaczoności wskazuje na fakt, że zwiększanie wartości WS o kolejne przyrosty ΔWS zbliżające WS do granicy „jeden” wymaga coraz większych nakładów energii (kosztów).

Identification of boundary values and features which describe a system operation safety is a crucial problem for assessment of the system operation safety. In this article, an attempt to match features necessary for a description of a given system operation safety and determine their boundary values, has been made. Determination of boundary values of safety features will allow to evaluate the system safety level. The following variables have been accepted as safety features: the number of accidents, the number of fatalities, and the number of people injured in those accidents. According to these values, probability values of the numbers of people who were killed and who were injured in those accidents have been established. Probability value equal to zero has been accepted as the intentional state, the interval between 0 and the mean value of a given feature determines the acceptable state, the interval between the mean value of a given feature probability and value 0.1 determines the boundary state, whereas all features assuming values higher than 0.1 refer to the system critical state. The presented research results are considered as directives for development of safety criteria for road transport systems and determination of their critical values. The proposed method of boundary values determination can be used for assessment of safety for different transport systems.

The problem area of safety can be dealt with in many different ways. In my opinion, one of the more and more often appearing problems of the globalized world is protection against threats existing in the sphere of health safety and prevention of threats connected with terrorism. It seems only too appropriate to begin considerations on the question of health safety and preventing the terrorism threat with an attempt at defining the multi-form notion of safety. The practice to date shows that the problem area is still raising numerous controversies. However, the question of safety dealt with in the first part of the present considerations was discussed in the context of two phenomena: prevention in the area of health safety and terrorism threat. Especial attention should be paid to two phenomena taking on two forms: terrorism and health safety. Even though the heterogeneity of the phenomena does not allow accepting uniform procedures within safety protection, the need to elaborate uniform strategies and preventive mechanisms appears to be the common denominator. I am aware of the fact that the presentation of the problems undertaken in this paper is of the fragmentary character only, but I hope that in the future it will provide a strong impulse to make further deepened analyses and conduct comparative research.

Introduction: Despite years of research and scientific work, it has not yet been possible to produce such a valuable medication as blood. The pandemic does not reduce the need for blood, quite the opposite. However, due to the pandemic, the number of blood donors has dropped dramatically across the country. The aim of the study was to find out the opinions and attitudes of the respondents towards blood donation during the pandemic period and to assess their knowledge of the principles related to safe blood donation during this period.Material and methods: The study was conducted using a diagnostic survey method and the tool was our own research questionnaire. The study was conducted in February 2021, using Google Forms platform. In total, data were collected from 150 individuals (females: 60.6%, males 39.4%) aged between 16 and 73 years (mean 31.4 ± 12.4 years). Statistical analyses used a significance level of p = 0.05.Results: Nearly 39.7% of the respondents were regular blood donors, 12% of the respondents donated blood several times (12.3%). Blood was donated more often by men, people aged over 30 years, urban residents, and people with higher education (p < 0.001). Most people continued to donate blood despite the COVID-19 pandemic (49.7%). Respondents who have donated blood so far still mostly want to donate blood after the pandemic (90%), among those who have not done so 38% want to do so after the pandemic (p < 0.001). The vast majority of respondents believed it was safe to donate blood during the pandemic (93%), and most were aware that symptoms of infection disqualify a blood donor (83.2%). Only 43.2% knew that “Convalescents who donate plasma are entitled to a blood donation deduction”.Conclusions: The current pandemic situation is not an obstacle to donating blood. Blood donations should not be withheld unless there are health contraindications. Due to additional procedures, it is still safe to donate blood. Efforts to promote blood donation during the COVID-19 pandemic should be continued.

The idea of European integration and frequently also subsequent unification of law in Europe may seem to be quite a recent topic. If it is talked about, it is more or less in scope of decades, or with regards to the recent change of era, it might be considered no earlier than a last century issue. However, the roots of European integration can be found, without any doubt, much earlier; namely at the time when the Roman Empire had not only been forming the European organization for many centuries, but also the history of part of the territory of African and Asian continent. Although the motivations of their masterminds were different, we encounter some efforts to assure durable peace through peace treaties between those who really wanted to achieve it. First agreements of this type – putting peace under penalties of international legal nature, were already known in Old age.

In project risk management many firms use bubble diagrams to get a graphical presentation of a project’s most uncertain attributes. The bubble diagrams and procedures used to put attributes into these diagrams are seen to provide a rational framework for managing risks. In this paper we review and discuss the use of these diagrams and procedures. Special attention is given to the way safety is treated. We show that the standard use of bubble diagrams is not adequate for identification and follow up critical activities that affect safety. The main problem is that the present structure means that the uncertainty is not properly taken into account. In this paper a reformulated bubble diagram is suggested that better reflects safety related uncertainties. The offshore oil and gas industry is the starting point, but the discussion is to large extent general.

Polish soldiers have been participating in peacekeeping and stabilization missions around the world for several decades under the auspices of the UN, OSCE, NATO and the EU. They were first sent to Korea in 1953 to oversee a ceasefire between the North and South Koreas. Since then, nearly 70,000 Polish troops have taken part in 58 peace and humanitarian multinational missions on different continents (SKMP ONZ, 2019), which required from them great skills to cooperate with soldiers from other countries, to overcome cultural barriers, as well as adaptation to difficult, often completely different than in Europe, climatic conditions, and to create a system of safeguards and procedures against dangerous tropical diseases. Due to these reasons, biological safety, i.e., medical, sanitary-hygienic, and anti-epidemic security of the contingent, plays a significant role in every mission because it allows the soldiers and civilian personnel stay healthy in an unfavorable and different climate and environmental conditions.

This article presents reflection made in the field of Roman legal thought in selected Polish legal regulations with potential impact on the functioning of the individual. The universal form of the principle – regardless of the legal system – implies a potential threat to the functioning of the individual in the form of uncertainty. The purpose of this publication is to indicate the need to update legal regulations regarding the indicated matter – in particular – in the form of an obligatory examination for the courts of the statute of limitations in a situation where a natural person is a party to the proceedings. Accurate provisions of the Code of Administrative Procedure, Code of Civil Procedure and selected court sentences were presented. In the research process, was made extensive use of qualitative research methods, including in the form of analyses (e.g.: legal and institutional analysis, comparative analysis, system analysis and methods: analysis and logical construction), generalization and implication. In turn, among quantitative research methods, intensively was used statistical analysis and a diagnostic sounding survey. In addition to the literature analysis – important support of the research process was the examination of documents (including provisions of national law) and available sources of knowledge about the problems studied. The source material included both open access and published studies in specialist journals. At this stage of the research, have been analysed the applicable legal regulations and selected sentences of Polish Courts. The mentioned above, empirical methods included the following: a diagnostic sounding survey – conducted in the form of surveys using the CAWI technique. The empirical stage ofthe research also consisted in the assessment of the legal status. The cognitive and utilitarian premises of the problems are the implementation of the adopted hypothesis: Ignorantia iuris nocet Principle in connection with numerous amendments to regulations may have negative consequences for the functioning of the individual.

In this paper is presented a concept of design procedure, and problems resulting from it, for floating docks with a view of taking into account their reliability and operational safety. It has been stressed that such design procedure is necessary for ensuring the docks appropriate pro-ecological features. It has been also shown that the design procedure should have several stages. The following kinds of design stages have been proposed to be accounted for : offer (canvassing) design, contract (ordered) design, concept (study) design, preliminary design, technical (classification) design and working design as well as the stage of elaboration of technical operational (delivery-acceptance) documentation. Knowledge areas necessary for such design procedure have been indicated. Attention has been also drawn to the necessity of accounting for, in designing the floating docks, diagnostic systems suitable to aid operational decision making .

Nuclear power plants supply nearly one sixth of the world electric energy production. Though nuclear power is a very efficient source of energy, it produces dangerous radioactive waste composed of nuclides characterized, among others, by a long decay time and containing also significant quantities of fissible and even fissile materials. Therefore, spent nuclear fuel must be carefully stored for at least hundreds of years, all this time needing permanent supervision. Simultaneously this cumbersome waste contains also important amounts of energy that should not be simply buried forever. Thus, in spite of the fact that ultimate disposal of spent nuclear fuel in adequate geological formations is recognized as safe for the energy hungry world that tries at the same time to avoid CO2 emissions, this is a hardly acceptable solution. Fortunately, there is an effective approach, namely – spent fuel recycling, particularly with the help of nuclear fusion. Simultaneously, one has to admit that this concept has not attained yet technological maturity, thus lengthy and costly investigations still are necessary before nuclear fusion achieves development level adequate to industrial application. Since every nuclear device must be generally safe, therefore this article raises a safety issue of fusion-fission hybrid design. In order to ensure the required reliability of evaluations the development of heterogeneous model of the device was assumed as the starting point for further respective research. The performed calculations have indicated that maintenance of subcriticality even in the case of system collapse is achievable.

The article describes the transport process and the drivers’ approach with regard to respecting the applicable driver's working time standards. This paper presents and discusses the results of a survey conducted among professional drivers, the primary purpose of which was to obtain the response to the question whether drivers actually rest during the break. Legal regulations strictly determine the minimum daily and weekly rest periods and the maximum daily and weekly driving times. Appropriate advanced technologies represented by measuring tools to the great extent oblige drivers to take a rest at the right time. Nevertheless, on the basis of the research it was stated that drivers frequently execute other activities, thus trying to increase their profits during break time, and therefore they commit for a rest shorter time than this resulting from the current working time regulations. The introduction of newer and more advanced solutions in the recording equipment substantially limits the possibility of performing other activities related to the vehicle during a break, and forces drivers to have a rest, thereby they pose less risk on the roads.
