The effects of the rolling process and microstructure on the brittle crack initiation and arrest of marine steel were systematically investigated. The microstructures of two steel plates produced by different rolling processes were observed and analyzed. The results demonstrated that the rolling process significantly influenced the microstructure. As the rolling temperature decreased, the grain size decreased, the high‐angle grain boundary (HAGB) content increased, and the average grain misorientation angle increased. The brittle crack initiation and the arrest abilities were evaluated by initiation fracture toughness and crack arrest toughness, respectively. The initiation fracture toughness and crack arrest toughness increased with the decreasing grain size and the increasing content of HAGBs. Finally, the influence of microstructure on the brittle crack initiation and arrest ability was explained from two aspects: (1) the critical event of crack initiation at low temperatures, and (2) the hindering effect of HAGB on the propagation of brittle cracks. Highlights: The average grain size decreased with the decreasing rolling temperature.The high‐angle grain boundary content and the grain misorientation angles increased with the decreasing rolling temperature.The critical fracture stress increased with the decrease in the critical crack size.The high‐angle grain boundary altered the brittle crack propagation path and improved the crack arrest ability.

Abstract Background During a critical event in the labor and delivery operating room, it is crucial for team members responding to the situation to be aware of the designated leaders. Visual and verbal cues have been utilized to designate leadership in various healthcare settings; however, previous research has indicated mixed results using visual cues for role designation. Methods The purpose of this study was to explore the use of the red surgical hat as a visual cue of leadership during obstetric emergency simulation training. We used a mixed-methods design to analyze simulation-based education video and debriefing transcripts. Results There was a statistically significant difference in the proportion of participants who declared leadership vs. those who donned the red hat. Participants were more likely to visually declare leadership utilizing a red surgical bouffant hat than to verbally declare leadership. Most participants indicated that observing the red hat to detect leadership in the operating room was more effective than when leaders used a verbal declaration to inform others who was leading. Conclusions Our findings suggest that utilizing a visual cue of leadership with the red surgical bouffant hat improves participant perceptions of communication of the surgical team during an obstetrical critical event in a simulation environment.

Introduction: The paper examines the psychological facet of innocent suffering. One can find a description of this phenomenon in social psychology as a factor that affects the belief in a just world, but there is a lack of qualitative scientific data about related psychological features, processes, copings, and consequences on the personality level. Methods: To study innocent suffering, semi-structured in-depth interview was conducted (31 respondents, ~223 minutes per respondent, 6,924 min in total) aimed to gather data about the experiences of innocent sufferings happened to participants. For the analysis of texts, a narrative and content analysis are used within the framework of grounded theory. The reliability of the results is based on expert assessment. Results and discussion: As a result, six essential properties of innocent sufferings were identified: complexity, stability, distress, injustice, casual incoherence, and breaks of integrity of a life story. The most “popular” life domains, in which participants reported about innocent sufferings, are violence, abuse (physical and psychological), and quitting romantic relationships. It is proposed a scientific definition of innocent suffering and the prototype of the phenomenon. [ABSTRACT FROM AUTHOR]

The purpose of this study was to understand the experience of second victim certified registered nurse anesthetists regarding the critical events in which they were involved, and the support received following the event. This was a mixed methods study and the quantitative portion consisted of the post-traumatic stress checklist-5 (PCL-5) survey deployed to random American Association of Nurse Anesthesiology members, two copies were completed; one with the stress levels and symptoms at the time of the critical event and the second was completed with the stress level and symptoms experienced regarding the event at the time of the study. The qualitative portion utilized hermeneutic phenomenology as its basis. The PCL-5 surveys were analyzed using the Wilcoxon matched-pair signed-rank test and a repeatedmeasures linear generalized estimating equations model was developed. The qualitative data supported the findings of the quantitative data. Initially stress levels were high but decreased over time. Stress levels may have fallen for a variety of reasons: support from colleagues and friends, increased event clarity. This study demonstrated that stress levels related to critical events decreased over time. Possible reasons for this are increased clarity about the event and other life-related distractions.

Today's rapidly changing living conditions and increasing consumer needs lead to continuous differentiation of working conditions. This situation builds extra stress on workers which leads to possible new risks and dangers where it causes accidents. For the safety of industrial plants the requirements are; systematically define the risks together with dangerous situations within the workplace and prioritize them, take the necessary precautions to control the hazards and finally maintain the continuity of improvements. In this study, international data sources have been reviewed for the definition of the frequency of critical events and route causes to make a prioritization between dangerous phenomenas. Besides, the transformation of a qualitative risk assessment to a quantitative structure have been investigated. Finally, a sample study has been conducted on a petroleum refinery atmospheric distillation column for the critical event defined as a liquid leak on the pipeline which goes to the scrubber. In the sample study, the dangerous phenomena with the highest occurrence frequency has found to be; “environmental damage caused by the leakage spread without ignition" with a frequency rate of 1, 73 10-6/year. Vapor cloud explosion has found to be the dangerous phenomena with the highest severity rate of 5,2 10-7/year. As a result it has been seen that besides taking precautions to prevent dangerous phenomenas it is also important to consider the severity and frequency of critical events.

Communication is critical to safe patient care. In this issue of the British Journal of Anaesthesia, Jaulin and colleagues show that use of a Post-Anaesthesia Team Handover (PATH) checklist is associated with fewer hypoxaemia events in the PACU, reduced handover interruptions, and other important metrics related to improved communication. The PATH checklist provides a link within a broader chain of safety checklists and other interventions that comprise a perioperative chain of survival. [ABSTRACT FROM AUTHOR]

By considering the emergence and threat of African Swine Fever (ASF) in Europe, this paper demonstrates the growing role of veterinary rationales in reframing contemporary human-wild boar coexistence. Through comparative ethnographies of human-wild boar relations in the Czech Republic, Spain and England, it shows that coexistence is not a predictable and steady process but is also demarked by points of radical change in form, course and atmosphere. Such moments, or wild boar events, can lead to the (re-)formation or magnified influence of certain discourses, practices and power relations in determining strategies of bio-governance. Specifically, this paper highlights how the spread of ASF in Europe has accelerated an already ongoing process of veterinarization, understood as the growing prominence of veterinary sciences in the mediation and reorganization of contemporary socioecologies. This example highlights how veterinary logics increasingly influence localized human-wildlife relations and, through analogous practices of biosecurity and control, also connect different places and geographic contexts.

Background: Failures in situation awareness cause two-thirds of anaesthesia complications. Avatar-based patient monitoring may promote situation awareness in critical situations.Methods: We conducted a prospective, randomised, high-fidelity simulation study powered for non-inferiority. We used video analysis to grade anaesthesia teams managing three 10 min emergency scenarios using three randomly assigned monitoring modalities: only conventional, only avatar, and split-screen showing both modalities side by side. The primary outcome was time to performance of critical tasks. Secondary outcomes were time to verbalisation of vital sign deviations and the correct cause of the emergency, perceived workload, and usability. We used mixed Cox and linear regression models adjusted for various potential confounders. The non-inferiority margin was 10%, or hazard ratio (HR) 0.9.Results: We analysed 52 teams performing 154 simulations. For performance of critical tasks during a scenario, split-screen was non-inferior to conventional (HR=1.13; 95% confidence interval [CI], 0.96-1.33; not significant in test for superiority); the result for avatar was inconclusive (HR=0.98; 95% CI, 0.83-1.15). Avatar was associated with a higher probability for verbalisation of the cause of the emergency (HR=1.78; 95% CI, 1.13-2.81; P=0.012). We found no evidence for a monitor effect on perceived workload. Perceived usability was lower for avatar (coefficient=-23.0; 95% CI, -27.2 to -18.8; P<0.0001) and split-screen (-6.7; 95% CI, -10.9 to -2.4; P=0.002) compared with conventional.Conclusions: This study showed non-inferiority of split-screen compared with conventional monitoring for performance of critical tasks during anaesthesia crisis situations. The patient avatar improved verbalisation of the correct cause of the emergency. These results should be interpreted considering participants' minimal avatar but extensive conventional monitoring experience. [ABSTRACT FROM AUTHOR]

The situation caused by the appearance of Covid-19 can be viewed as a critical event: typologically, it is an unprecedented event, which requires and shapes new forms of historical action hitherto unknown in the given context. Critical events serve as strong value and emotional landmarks in the cultural cognition of each social environment, and form the basis for a meaningful determination towards other events. Using material collected primarily from the online versions of electronic and printed media, we consider how the reality they presented is shaped through the news through the statements of politicians and medical doctors in Serbia. We trace how the narrative transformation of socio-cultural reality took place from the time before the of Covid-19 outbreak in our country to the time immediately after the lifting of the state of emergency declared due to that infection. The premise of all that is being done to tackle the infection is not a purpose in itself, but aims to enable a return to the life we were accustomed to before the outbreak of the epidemic. Covid-19 destabilizes our everyday life – a life that consists of work or study, use of free time, socializing etc. Such everyday life is a reference point of "normalcy". Socio-cultural normalcy refers to all that is understood as a normal and undisturbed course of everyday life. The appearance of Covid-19 gave rise to the notion of the "new normal", that is, a course of everyday life that is similar to normal, ordinary life, but with adherence to measures aimed at preventing the spread of infection by the authorities. In the paper we deal with the period that begins just before the outbreak of Covid-19 in our country, and ends with the period after the lifting of the state of emergency, to show the discursively produced picture of social reality in which the concept of the "new normal" serves as a cultural cognitive tool for understanding a situation in which one has to live with Covid-19 in order to one day be able to return to the way of life that existed before it.

The inspiration for writing this article is on the one hand, the critical event caused by the COVID-19 pandemic that is being shared by all people around the world and that affects us all universally. On the other hand, it is my academic experience, shared by my colleagues - academic teachers. Therefore, the research I conducted meets all the conditions of critical engaged research: it stems from my own biographical experiences, it is an important opinion on the issue, it is rooted in the current, critical social event and it is aimed at unmasking, revealing real social practices and behaviors. Described below are the styles of managing institutions of higher education (of different kinds - vocational, academic, etc.) in a critical event related to the COVID-19 pandemic. Which management styles are being updated in a critical situation, which are selected and preferred by management, and what are the consequences? These are the questions I will try to answer. In accordance with aforementioned declarations, I will do it based on interviews with the authorities of several Polish institutions of higher education, as well as on the basis of autoethnography.

The terror attacks in Norway 2011, targeting what the perpetrator described as proponents of immigration and multicultural society, created exceptional circumstances for people to reflect on issues of belonging. In this kind of situation, it is assumed that people emphasise their affinity with the affected country. This, in turn, makes the problematisation of the affinities displayed particularly interesting since the act of expressing them even in a very taxing situation indicates their importance. Texts by individuals from ethnic minorities, written soon after the attacks, are analysed in terms of conceptions of ‘Norwegianness’. Results show explicit support for civic values but also multiple expressions of not feeling recognised as part of majority society also from individuals obviously acculturated to Norwegian lifestyles and cultural codes. These expressions are explained in terms of whiteness – non-whiteness and religion.

We propose a psychological need detection framework which automatically identifies people needs and measures their satisfaction level. The framework employs three need models, which are developed using psychological, linguistic, and Twitter-specific features. We evaluate the performance of the proposed models on psychological need data sets which are annotated by psychologists. The models obtained encouraging results: 78.71% in recognizing need content, 81.96% in identifying need type, and 93.56% in measuring need satisfaction level. We use the proposed framework to recognize individual needs and measure their satisfaction level in response to the Florida shooting event, which occurred on February 14, 2018, and the related March for Our Lives event which followed on March 24, 2018. Timeline-based visual and textual representations are generated to explain the motivation behind public reaction and behavior.

Traumatic aortic rupture (TAR) is a highly fatal injury mechanism resulting from blunt deceleration forces against the descending aorta. The mechanism of TAR is directly attributed to the aorta suffering damage by indirect shearing forces. The descending aorta remains fixed to the posterior chest wall, while the heart and ascending aorta are exerted forward, thus causing the intimal tear. A characteristic triad presents as increased blood pressure in the upper extremities, decreased blood pressure in the lower extremities, and a wid- ened mediastinum on radiography. Early recognition of signs and symptoms of the mechanism of injury is key to initiating early damage control surgery and ultimately decreasing morbidity and mortality. This case report describes the intraoperative management of an elderly female patient with TAR following a motor vehicle collision in a remote location in rural Pennsylvania. [ABSTRACT FROM AUTHOR]

Early recognition of intraoperative critical events is essential in optimizing the health outcomes of surgical patients. Use of simulation in nurse anesthesia education allows students to practice recognizing changes in the patient's condition in a safe learning environment. Second- and third-year student registered nurse anesthetists were randomly assigned to 2 groups to explore differences in recognizing intraoperative myocardial infarction (MI) using highfidelity mannequin simulation vs virtual simulation. One group participated in a virtual simulation first, followed by a high-fidelity mannequin simulation. The other group participated in a high-fidelity mannequin simulation first, then virtual simulation. Second-year students recognized an intraoperative MI faster when using high-fidelity mannequin simulation than when using virtual simulation. However, there was no significant difference among third-year students in the time it took to recognize a critical event when using high-fidelity mannequin simulation vs virtual simulation. These findings indicate that both simulation modalities are useful in evaluating student registered nurse anesthetists' timely recognition of intraoperative critical events such as MI. However, for students with less didactic and clinical practicum experience in the program, such as second-year students, the use of high-fidelity mannequin simulation for recognizing an intraoperative MI may be more beneficial than virtual simulation.

Coarse grain heat affected zone (HAZ) of F460 steel was simulated by a Gleeble 3800 thermo-mechanical simulator. The microstructure, critical event of the HAZ formed at various heat inputs (E) were characterized and determined by optical microscopy (OM) and scanning electronic microscopy (SEM), and cleavage fracture stress σf was also calculated by ABAQUS software. Based on above systematic analysis, the intrinsic mechanism of ductile-brittle transition for F460 steel heat affected zones with different heat inputs were revealed. The results indicate that:with the improvement of heat input, the microstructures in sequence are a minority of lath martensite and massive fine lath bainite, more lath bainite with less granular bainite, more granular bainite with less lath bainite, bulky of granular bainite; and the maximum size of the original austenite grain and bainite packet becomes bigger with the improvement of heat input. The size of bainite packet is critical event of the cleavage fracture for coarse grain heat affected zone specimens with various heat inputs by comparing the relationships among residual crack length, original austenite grain size and bainite packet size. With the decreasing of the bainitic packet, the ductile to brittle transition temperature decreases. In addition, cleavage fracture stress σf is also calculated by ABAQUS software, σf gradually decreases with the increase of the heat input, which can explain the intrinsic mechanism of ductile to brittle transition temperature Tk with the change of the heat input.

Rapid perception and processing of critical monitoring events are essential to ensure healthy operation of Internet of Manufacturing Things (IoMT)-based manufacturing processes. In this paper, we proposed a framework (active sensing and processing architecture (ASPIE)) for active sensing and processing of critical events in IoMT-based manufacturing based on the characteristics of IoMT architecture as well as its perception model. A relation model of complex events in manufacturing processes, together with related operators and unified XML-based semantic definitions, are developed to effectively process the complex event big data. A template based processing method for complex events is further introduced to conduct complex event matching using the Apriori frequent item mining algorithm. To evaluate the proposed models and methods, we developed a software platform based on ASPIE for a local chili sauce manufacturing company, which demonstrated the feasibility and effectiveness of the proposed methods for active perception and processing of complex events in IoMT-based manufacturing.

A method of predicting the influence random events on the critical functionality of an object is discussed. Research is performed regarding the possibility of extending a prediction model to a prediction system by functionally uniting this model with additional models or recognizing the type of influence of a random event on a complex technical object. The proposed solution is importatnt because executing a prediction system instead of a prediction model allows one to detect critical situations that, when influencing technical objects, can result in the catastrophic loss of functionality of the corresponding objects.

Most anesthesia providers will experience at least one perioperative critical incident during their career, potentially causing critical incident stress symptoms that may affect their ability to provide patient care. The purpose of this descriptive pilot investigation of Certified Registered Nurse Anesthetists (CRNAs) was to determine if their knowledge of the psychological and physical ramifications of critical incidents, coping strategies to deal with critical incident stress, and satisfaction with departmental handling of critical incidents improved when a formal, institutionally relevant critical incident stress management policy and protocol was developed and implemented. Knowledge of the effects of a critical incident, available coping strategies, and the perceived value of a stress management support protocol were assessed by surveys conducted before and after the implementation of a formal educational program. The results demonstrated that knowledge of critical incident stress and coping strategies improved with a staff educational program, with 25 of 26 respondents (96%) reporting that having a departmental critical incident stress management policy and protocol in place was valuable. This pilot investigation indicates that supportive protocols and education programs for critical incident stress management are beneficial and increase the CRNAs' confidence in their ability to cope with critical incidents.

Debriefing is an essential procedure for identifying medical errors, improving communication, reviewing team performance, and providing emotional support after a critical event. This study aimed to describe the current practice and limitations of debriefing and gauge opinions on the best timing, effectiveness, need for training, use of established format, and expected goals of debriefing among Portuguese anesthesiologists., Methods: We performed a national cross-sectional online survey exploring the practice of anesthesiologists' debriefing practice after critical events in Portuguese hospitals. The questionnaire was distributed using a snowball sampling technique from July to September 2021. Data were descriptively and comparatively analyzed., Results: We had replies from 186 anesthesiologists (11.3% of the Portuguese pool). Acute respiratory event was the most reported type of critical event (96%). Debriefing occurred rarely or never in 53% of cases, 59% of respondents needed more training in debriefing, and only 4% reported having specific tools in their institutions to carry it out. There was no statistical association between having a debriefing protocol and the occurrence of critical events ( P =.474) or having trained personnel ( P =.95). The existence of protocols was associated with lower frequencies of debriefing ( P =.017)., Conclusions: Portuguese anesthesiologists know that debriefing is an essential process that increases patient safety, but among those surveyed, there is a need for an adequate debriefing culture or practice., Trial Registration: Research registry 7741 (https://www.researchregistry.com/browse-the-registry#home)., Competing Interests: J. Berger-Estilita is an associate editor for BMC Medical Education and has received travel expenses from Medtronic for the Save the Brain Initiative training.

In this article we ask if central values which people were in dialogue with in the memorial messages from Oslo Cathedral Square in the aftermath of July 22nd 2011, may be seen as a part of Norwegian cultural memory, and if so, how. We answer this question in the affirmative, by elaborating on presentations of the Norwegian flag as a symbol of the values unity and solidarity, and on presentations of love and roses as weapons promoting the values love, humanity and calmness. In our discussion we have drawn on theory of cultural memory and suggested that the use of the Norwegian flag in the messages may be understood in the frame of Assmann’s term “canon”, representing the active part of cultural remembrance, and that the message from the use of roses and hearts may be understood in the frame of the term “archive”, representing the passive part of remembrance
