Opis:
Telecommunication systems become a key component of critical infrastructure. One of the main elements of such systems is computer system. The organizations which can be involved in crisis management (e.g. government agencies, etc. ) need to know results of security drawbacks in their systems. Moreover, they should have a tool for analysing the results of decision made in security context. And often the following question is raised: why do security systems fail? To answer it in this paper the aspects of reliability are discussed. From this point of view the security systems are analysed. We hope that thanks to such approach we will be able to reach some characteristics of security incidents occurrence. Moreover, we hope to use our results to build security attributes metrics. In addition, we present thesis that predictions of occurrence of incidents is impossible, so we should focus on registration of incidents type. On such a foundation we can formulate conclusions about drawbacks in configurations or administration of information systems. In our research we have observed that in case of some class of information systems, the availability incidents are the most dangerous. And we conclude that only using technologies with good reliability characteristics can lead to solving this problem.

Opis:
The maritime industry is undergoing a rapid evolution through the introduction of new technology and the digitization of existing services. At the same time, the digital attack surface is increasing, and incidents can lead to severe consequences. This study analyses and gives an overview of 46 maritime cyber security incidents from the last decade (2010-2020). We have collected information from open publications and reports, as well as anonymized data from insurance claims. Each incident is linked to a taxonomy of attack points related to onboard or off-ship systems, and the characteristics have been used to create a Top-10 list of maritime cyber threats. The results show that the maritime sector typically has incidents with low frequency and high impact, which makes them hard to predict and prepare for. We also infer that different types of attackers use a variety of attack points and techniques, hence there is no single solution to this problem.

Opis:
Critical infrastructures (CI) are organizations and facilities of major importance and form the backbone of a national economy, security and health. Due to their significance, they may become target of an attack such as terrorist resulting in crisis event. Decision making systems to support and facilitate the operation of emergency health services in major incidents and crises, could play a significant role. In order to support those systems, efficient databases that could store and manage data from different sources, multiple levels of user privileges within a secure environment become a necessity. In this work, we propose and develop the WARSYS component. The main advantage of WARSYS database, is the ability to collect and store information from different sources providing appropriate interfaces. The WARSYS database structure will be developed within IMPRESS framework, with a view of extracting in real time, medical and logistics information from available repositories.

Opis:
In recent years, the aviation sector has been developing dynamically. The constant increase in the number of passengers contributes to an escalation in the number of air operations. This trend is mainly due to the increased traffic not only in airspace but also within airports. The large concentration of aircraft at the largest airports makes ground-flying phases such as taxiing or take-off becoming a challenge for pilots, ground services, and air traffic controllers. An intensive operation of many objects on the airport's manoeuvring areas can lead to collisions between them. Global air traffic is growing constantly, with record numbers of air operations and passengers carried. The probability of a collision increases, which leads not only to the cancellation of the flight but also to the significant costs of the aircrafts repair. The statistical analysis allows to highlight the problems related to the issue of ground collisions at airports and can also confirm the thesis concerning the growth and density of air traffic.

Opis:
A comprehensive risk analysis makes use of different datasets. Marine incidents data are essentially important datasets. The purpose of this study is to analyse marine incident databases in the BSR (Baltic Sea Region). The marine incident data in the region are inhabited by a wide rage of issues, such as limited data accessibility and availability, and the diversity in data quality, structure, amount, accuracy, degree of detail and languages. Preparing for the data analysis is a very cumbersome, labour intensive, time consuming and expensive process. Merging different datasets from different countries into a single dataset is a very difficult process, if not impossible for a complete data merging. The paper provides experiences on how to overcome some of these issues and proposes some suggestions for improvements in the future.

Opis:
The paper examines the concept of social rights from both the analytical and philosophical perspective. In the first part of the paper a distinction is made between social rights in the strict sense (called in the paper “Type 1 social rights”), which can be decomposed into the Hohfeldian incidents, and social rights which resemble norm-goals and therefore cannot be decomposed into the Hohfeldian incidents (these rights are called in the paper “Type 2 social rights”). It is argued that even though Type 1 social rights are rights in the strict sense, they exhibit certain idiosyncrasies distinguishing them from “classical” rights, among which the most striking idiosyncrasy is their double correlation to duties. The second, philosophical part presents various ways in which social rights can be justified. A special emphasis is laid on the justification appealing to the concept of autonomy. Some standard criticisms of social rights are also evaluated.

Opis:
This article presents structure and analysis of possible events for information security of a production company. The aim of the analysis is to identify incident events, their time and frequency. The analysis includes occurrence of notifications, threatening events, employee errors and false alarms. Also, the conducted research takes into account the functions performed in the enterprise. For these events, a daily distribution of events and statistical analysis of their occurrence were developed. Thanks to the analysis of the phenomena in time, enterprises can introduce actions preventing the occurrence of incidents. The conducted research has shown that employees report incidents which, in their opinion, constitute an incident, which greatly facilitates the work of the information security administrator. These events are analyzed and classified accordingly. The analysis showed that most events take place between midnight and two in the morning. The conducted analysis is a pilot study carried out in one large enterprise in the metallurgical industry.

Opis:
The current state of the art and dedicated applications in Early Warning Systems (EWS) of hydrological and meteorological threats are presented herein. Special emphasis is placed on systems based on the post-processing of deterministic numerical weather forecasts in the real-time mode. The importance of climate and weather forecasting models in providing warnings against slow and rapid onset rates e.g. drought and dispersion of atmospheric pollutants respectively, is discussed. It is strongly suggested that there is a need for systems, corresponding to crisis situations in the field of environmental hazards and/or human activities in general, that would be able to provide support and information about further possible scenarios with a projected state of both the environment and the possibility of the negative impact of various factors on the population (human communities). Since there are highly developed plans for the construction of a nuclear power plant in Poland, there is an urgent need to prepare adequate tools that will help avoid crisis situations, or at least to minimize their negative effects. The Early Warning System should be considered one such tool, to be used not only for its economic benefits, but also for pro-social areas of services responsible for the appropriate reaction to crisis events.

Opis:
This paper discusses diagnostic abilities of novice teachers of English as a foreign language in Poland as demonstrated through analyzing critical incidents (CIs). A case study, designed to explore patterns and regularities in cognitive processes that practitioners activate to examine disorienting situations in their educational context, provided evidence of effective mental work of beginner teachers at the verbal and conceptual levels. Specifically-structured written reports on what the instructors considered critical moments in their teaching practice served as a tool to verbalize how they represent, interpret, and value phenomena in the FL classroom by activating and integrating various sources of professional knowledge. The data analysis, which included both identification of the character of mental representations the subjects stimulated during the recall as well as higher order thinking operations on these representations, led to the conclusion that the inexperienced teachers show a degree of efficacy to register relations and variation in classroom realities, to problematize the unproblematic, to take position on matters, and to formulate relevant feedback for their future didactic moves. This encourages a hypothesis that teachers’ diagnostic abilities are not necessarily determined by the current state of their professional expertise and that limited classroom experience does not suppress adequate cognitive and affective responses to problems in beginner practitioners.

Opis:
The current state of knowledge and the latest trends and examples of decision support systems (DSSs) are presented in this paper. Special emphasis was placed on a DSS proposal based on post-processed numerical weather forecasts operating in a real time. There is an essential need for decision support systems that can react to any incidents – including those that pose a risk to the natural environment or human activity in general. For this purpose an exemplary system has been prepared, which was – from its conception to implementation – the original idea of the author. The system enables communication with the user via a graphical user interface that controls the operation of the program, the course of the algorithm and the data flow. The system is modular, allowing the connection of other applications to carry out the work of a DSS. A basic view of the operating window and working panels have been designed for proper demonstration of various types of information and visualizations – the substantial products and results of the system. Further research in the field of DSS of this kind should be the implementation within the RIOT system of mechanisms of notification and response to crisis events related to extreme weather phenomena (whirlwinds, intensive rains, strong frosts or heats).

Opis:
The article presents interpretations of the concepts of cybersecurity and cybercrime as well as the abuse of the term cybernetic. The author refers to information as a new “centre of gravity” of the nation’s power and special attention is paid to activities aimed at ensuring a high level of information security in Poland. The assumptions of the draft Act on the national cybersecurity system are described and particular emphasis is placed on the issues of technical and organisational reporting and the handling of ICT security incidents. The author points out that handling incidents violating cyber security at a strategic level for a country ought to be considered as an intentional action of a definite and repeatable character. Here the reference to the ISO/IEC standards and recommendations can be found. Moreover, behaviours related to securing digital evidence after an incident, including the so-called good practice in relation to the reaction in the event of an incident, are presented. A simplified procedure for securing computer hardware, as a recommended method of action in case of the triage and live data forensics, are suggested in the article. The recommendations of the FORZA methodology and frameworks are also discussed. When summarising, the author underlines that it is essential to prepare appropriate procedures and personnel for the broadly understood handling of incidents violating cybersecurity. This includes protection of digital evidence according to the procedures, good practice and suggestions contained in normative documents, as well as implementing cybersecurity policy, bringing legislation into line with international standards and educating users and the judiciary.

Opis:
The paper introduces the concept of a critical incident (CI) in the context of foreign language teaching and discusses its importance for teachers` professional development as a factor leading to a teacher´s awareness of his/her classroom. The ability to diagnose critical incidents is seen as an inseparable part of a teacher´s ability to control the teaching context and thus create critical events (CE). This paper also introduces the concept of an appraisal system (Smith and Lazarus 1993 ), understood as one´s evaluation of the relationship between one´s success and failure in respect of past experience and the ability to adapt to an immediate context. In my analysis I will follow Scherer´s (1984) taxonomy of components of appraisal systems such as novelty, the pleasantness of a task and coping potential, among others. This appraisal system is seen as emotionally-driven but it also emphasizes the cognitive dimension and the interaction between affective and cognitive processing. In the empirical part of the paper, the study on CI in teaching EFL is reported on. The main objective of the study was to make in-service teachers of EFL reflect upon their most memorable critical incident (CI) and evaluate it from the affective point of view. The study was also to make the subjects more aware of themselves and their classroom presence. The research instrument used in the project was the Geneva Appraisal Questionnaire -GAQ (Scherer 2001), based on Scherer´s taxonomy.

INTRODUCTION: Out-of-hospital cardiac arrest (OHCA) is one of the leading causes of death in developed countries, which is a leading public health problem. Saving endangered human life is a priority task for emergency services around the world. The aim of study was to analysis of OHCA cases for which the Fire Rescue Units (FRU) teams were ordered in situations that meet the criteria of the isolated emergency medical incidents (IEMI). MATERIAL AND METHODS: The study included a retrospective analysis of calls by Polish FRU to local medical threats over a period of 5 years. The data come from the Decision Support System for Fire Service. Quantitative data were described using classical measures: arithmetic means (M), standard deviations (SD), median (Me) and interquartile ranges (IQR). RESULTS: The total number of OHCA cases included was 94. The mean time between receipt of the IEMI call and arrival on scene was 6 minutes and 22 seconds (IQR = 4). ROSC occurred in 21 patients, which is 22.34% of all cases. An Automated External Defibrillator (AED) was used in 64 cases (68.09%). The analyzed victims were mostly men (76.59%). The mean age of the victims was 63.06 years (Me = 62 years). CONCLUSIONS:The results of the research are in line with global trends and show the role of early cardiopulmonary resuscitation. Sending FRU to OHCA in the case of non-availability of the EMT in the initial phase of the intervention is justified.

Opis:
Safety in aviation has various connotations. According to the International Civil Aviation Organization (ICAO), it is a state in which the possibility of harm to people and property is minimised and maintained within a continuous process of identifying threats and managing safety risks at an acceptable level or below an acceptable level. Actions related to threat identification can be reactive, proactive, or predictive. Reactive actions aim to verify what happened, why, and how to prevent it from recurring. For this purpose, incidents that occurred in the past are analysed. By Polish law, the Commission for Investigating Aviation Accidents investigates accidents and serious incidents, while incidents mostly fall under the responsibility of the aviation organisation in which the incident occurred. Therefore, this article aims to identify threats causing incidents. Three thousand two hundred aviation incidents reported between 2017 and 2022 to the Civil Aviation Office as part of the mandatory and voluntary event reporting system were analysed. The identified causes, due to the diversity of their description, were divided into four groups. The first group consists of human factors, representing inadequate actions by pilots, crews, or individuals who caused a situation of danger. The second group comprises errors in the operation of technical objects, including aircraft. This group also includes situations where foreign objects violate airspace or minimum conditions are breached. The next group includes environmental causes such as wild animals, birds, and weather conditions. The last group consists of procedures related to flight phases.
