Safety of the express freight train running over a long-span bridge

Purpose-Express freight transportation is in rapid development currently.Owing to the higher speed of express freight train,the deformation of the bridge deck worsens the railway line condition under the action of wind and train moving load when the train runs over a long-span bridge.Besides,the blunt car body of vehicle has poor aerodynamic characteristics,bringing a greater challenge on the running stability in the crosswind.Design/methodology/approach-In this study,the aerodynamic force coefficients of express freight vehicles on the bridge are measured by scale model wind tunnel test.The dynamic model of the train-long-span steel truss bridge coupling system is established,and the dynamic response as well as the running safety of vehicle are evaluated.Findings-The results show that wind speed has a significant influence on running safety,which is mainly reflected in the over-limitation of wheel unloading rate.The wind speed limit decreases with train speed,and it reduces to 18.83 m/s when the train speed is 160 km/h.Originality/value-This study deepens the theoretical understanding of the interaction between vehicles and bridges and proposes new methods for analyzing similar engineering problems.It also provides a new theoretical basis for the safety assessment of express freight trains.

A Knowledge Management Framework of the Information Technology-Based Approach for Improving Occupational Safety Training of Young Workers

This paper aims to develop a novel knowledge management framework for improving the system of pro-safety attitudes among young worker population in Poland. This is done through an efficient use of existing sources of explicit and tacit knowledge in the field of vocational occupational safety and health （OSH） training. This project identifies three specific research steps for the development of the knowledge management framework of the information technology-based approach for improving occupational safety training of young workers, including： （1） the development of the conceptual model of the flow of explicit knowledge of OSH; （2） evaluation of the effectiveness of formal and explicit knowledge sources for OSH and training methods using these sources in the context of attitudes towards health and safety at work; and （3） verification of the proposed model of vocational training with the use of combined explicit and hidden knowledge. The proposed framework includes consideration of the effectiveness of the formal and informal sources of safety knowledge. A mapping from the formal sources of explicit knowledge about the occupational safety to expected attitudes （hidden knowledge） towards OSH outcomes, including emotional, cognitive, and behavioral aspects has been used. The above framework should help to improve the system of vocational training for young workers in Poland.

Intensive Training for Stroke: Evidence of Safety from Meta-analysis and Systematic Reviews

[Objectives] To investigate the safety of intensive training for stroke recovery. [Methods] A systematic electronic search was conducted up to December 1 st , 2022, and the number of falls and fall-related injuries, as well as other adverse events, were extracted. Odds ratios (ORs) were calculated to assess the two intervention methods, and a 95% confidence interval (95% CI) was calculated for each of them to ensure the statistical accuracy of the results. The heterogeneity of the included studies was also tested. [Results] Five moderate to high quality studies comprising a total of 184 participants were included in this review. All five randomized controlled trials reported adverse events, including falls that did not result in injury, pain in the joints, back, muscle, or chest, and skin injuries such as cuts, bruises, and scrapes. The pooled analysis of these trials showed no statistically significant differences between the intensive training and control groups in terms of falls ( P =0.35) , pain ( P =0.07), or skin injuries ( P =0.90). [Conclusions] This review provides good evidence to suggest that intensive training is safe and feasible as a novel intervention during the stroke recovery.

Pressure waves acting on wall of a tunnel and their impact on the tunnel's structural safety

The transient pressures induced by trains passing through a tunnel and their impact on the structural safety of the tunnel lining were numerically analyzed.The results show that the pressure change increases rapidly along the tunnel length,and the maximum value is observed at around 200 m from the entrance,while the maximum pressure amplitude is detected at 250 m from the entrance when two trains meeting in a double-track tunnel.The maximum peak pressure on the tunnel induced by a train passing through a 70 m^(2) single-track tunnel,100 m^(2) double-track tunnel and two trains meeting in the 100 m^(2) double-track tunnel at 350 km/h,are−4544 Pa,−3137 Pa and−5909 Pa,respectively.The aerodynamic pressure induced axial forces acting on the tunnel lining are only 8%,5%and 9%,respectively,of those generated by the earth pressure.It seems that the aerodynamic loads exert little underlying influence on the static strength safety of the tunnel lining providing that the existing cracks and defects are not considered.

Operational Safety Assessment of a High-Speed Train Exposed to the Strong Gust Wind

The operational safety characteristics of trains exposed to a strong wind have caused great concern in recent years.In the present paper,the effect of the strong gust wind on a high-speed train is investigated.A typical gust wind model for any wind angle,named“Chinese hat gust wind model”,was first constructed,and an algorithm for computing the aerodynamic loads was elaborated accordingly.A vehicle system dynamic model was then set up in order to investigate the vehicle system dynamic characteristics.The assessment of the operational safety has been conducted by means of characteristic wind curves(CWC).As some of the parameters of the wind-train system were difficult to measure,we also investigated the impact of the uncertain system parameters on the CWC.Results indicate that,the descending order of the operational safety index of the vehicle for each wind angle is 90°-60°-120°-30°-150°,and the worst condition for the operational safety occurs when the wind angle reaches around 90°.According to our findings,the gust factor and aerodynamic side force coefficient have great impact on the critical wind speed.Thus,these two parameters require special attention when considering the operational safety of a railway vehicle subjected to strong gust wind.

Hidden Dangers and Preventive Measures in the Inventory of Articles in Operating Room

Operating Room is an important place for surgical diagnosis and treatment and rescue of patients. With the rapid development of medical technology, high, precision, sharp continuous development, operating room safety management is particularly important. The error of the counting of the surgical articles causes the foreign body left in the patient’s body, which will cause irreversible damage to the patient and even cause the medical dispute and touch the legal problem. Operation items inventory system is an important working system in the operating room. Scientific and standardized methods and systems for counting surgical instruments and dressings during operation can prevent foreign bodies from being left in the body, prevent errors and accidents in the operating room, and are very important for ensuring the safety of the operation of patients. In order to ensure the safety of patients, it is necessary to ensure the correct inventory of surgical items. The factors affecting the accuracy of item counting in the operating room and the preventive measures are summarized as follows.

Evaluating the impact of safety pictogram training on comprehension scores and knowledge retention among engineering students

Safety pictograms are essential tools for identifying workplace hazards by providing critical information about health hazard risks,fire safety,emergency evacuation,and accident prevention.Effective safety pictogram training programs are necessary to enhance workers'knowledge of these pictograms.This study evaluates the effectiveness of a safety pictogram training program on the comprehension and retention of knowledge among engineering students.A total of 262 participants were asked to predict the meaning of 22 safety pictograms regulated by International Organization for Standardization(IsO)7010 before and after a one-hour online training session.A follow-up test was administered six months later to assess long-term knowledge retention.Results showed that the average comprehension rate increased from 60.1%before training to 68.3%after training,with a retention rate of 66.0%six months after training.The study found that training positively affected comprehension of emergency and mandatory action pictograms,while lower scores were observed for warning pictograms.Statistical tests revealed a significant effect of training on comprehension levels 16 out of 22 pictograms,with an average increase in comprehension of 11.2%.Of these 16 pictograms,the comprehension level of 10 pictograms increased after training and remained at the same level six months later.However,the scores decreased slightly six months after the intervention,indicating the need for continued reinforcement or retraining.These findings have important implications for safety education and training programs,particularly in industries where safety hazards are widespread.The positive impact of training on comprehension scores highlights the ongoing need to improve safety pictogram comprehension to consistently meet standard acceptance criteria.Future training programs may need to focus on categories such as warning pictograms and fire equipment and fire action pictograms,which exhibited lower comprehension scores,to ensure better employee understanding.

Use of the global rating scale helps clinicians advise hospital administration on the prior it ies for a quality training program.

Optimization on the Crosswind Stability of Trains Using Neural Network Surrogate Model

Under the influence of crosswinds,the running safety of trains will decrease sharply,so it is necessary to optimize the suspension parameters of trains.This paper studies the dynamic performance of high-speed trains under cross-wind conditions,and optimizes the running safety of train.A computational fluid dynamics simulation was used to determine the aerodynamic loads and moments experienced by a train.A series of dynamic models of a train,with different dynamic parameters were constructed,and analyzed,with safety metrics for these being determined.Finally,a surrogate model was built and an optimization algorithm was used upon this surrogate model,to find the minimum possible values for:derailment coefficient,vertical wheel-rail contact force,wheel load reduction ratio,wheel lateral force and overturning coefficient.There were 9 design variables,all associated with the dynamic parameters of the bogie.When the train was running with the speed of 350 km/h,under a crosswind speed of 15 m/s,the benchmark dynamic model performed poorly.The derailment coefficient was 1.31.The vertical wheel-rail contact force was 133.30 kN.The wheel load reduction rate was 0.643.The wheel lateral force was 85.67 kN,and the overturning coefficient was 0.425.After optimization,under the same running conditions,the metrics of the train were 0.268,100.44 kN,0.474,34.36 kN,and 0.421,respectively.This paper show that by combining train aerodynamics,vehicle system dynamics and many-objective optimization theory,a train’s stability can be more comprehensively analyzed,with more safety metrics being considered.

Pendulum systems for harvesting vibration energy from railroad tracks and sleepers during the passage of a high-speed train: A feasibility evaluation

We evaluate the feasibility of recovering energy from the vibrations of track and sleepers,during passage of a high-speed train,by means of a pendulum harvester.A simple mathematical model of the parametric pendulum is employed to obtain numerical predictions,while measured data of vibration tests during the passage of a Thalys high-speed train are considered as input forcing.Since a sustained rotation is the most energetic motion of a pendulum,the possibility of achieving such state is evaluated,taking into account the influence of initial conditions,damping and other factors.Numerical simulations show that rotating pendulum harvesters with sufficiently low viscous damping could be able to generate a usable average power on the order of 5–6 W per unit.Considering a modular arrangement of devices,such energy is enough to feed variety of rail-side equipment,as wireless sensors or warning light systems.However,a suitable choice of initial conditions could be a difficult task,leading to the need of a control action.

Investigating the future study area on VR technology implementation in safety training: A systematic literature review

Safety training is the exercise normally conducted for all the current and future employees of a company to identify and recognize occupational hazards and diseases as well as determine the appropriate controlling methods.Moreover,virtual reality(VR)is a technology developed to virtually simulate the surrounding envi-ronment to ensure immersive experience and interaction through artificial three-dimensional(3D)platforms.VR devices have been developed to be more compact,easy to use,and affordable to enable people to enjoy immersive virtual experiences and provide interactive and realistic content.This has made technology one of the most popular forms of media for different kinds of training,such as safety-related ones.Therefore,this study aimed to review the use of VR in safety training through the systematic literature review(SLR)method.The process focused on developing 4 primary questions(PQs)classified into 11 systematic research questions(SRQs)for discussion points concerning current developments in VR technology applications.These were further combined with the preferred reporting items for systematic reviews and meta-analyses(PRISMA)flow diagrams in selecting the relevant literature.The questions were also used to investigate the scenarios,methods,objectives,and outcomes of previous studies.The results showed the need for further studies on the application of VR technology in safety training in other fields such as firefighting,chemical industry,maritime,etc.Furthermore,several scenarios such as construction design,disaster response,rescue procedures,and others need to be included.This study also provides information on the gaps for future study,including the exploration of a broader range of industries and VR scenarios.

Anesthesia Alert—A Preoperative Safety Concept for the Surgeon

Background: Advances in modern medicine and surgical technique have allowed patients with multiple comorbidities to undergo invasive surgery electively. This places additional stress on hospital resources to anticipate and deal with potential complications. We have introduced a preoperative safety concept called “Anesthesia Alert”. The surgeon or preoperative interviewing anesthesiologist assigns an Anesthesia Alert when booking to denote possible difficulty with anesthesia induction or intubation. As a result, two anesthesiologists and fiber optic equipment are made available on the day of surgery. Methods: A retrospective study of patients from all surgical specialties who were assigned Anesthesia Alerts between January 2012 and November 2012. Records were analyzed for reasons requiring Anesthesia Alerts. Patient demographics, comorbidities, and perioperative complications were reviewed. Results: A total of 112 patients formed this study group. Difficult airway comprised the majority of Anesthesia Alerts (n = 75, 67.0%). Hypertension was the most prevalent comorbidity among patients. There were only 7 patients (6.3%) admitted to the ICU postoperatively and no mortalities. Conclusion: Perioperative patient safety is an evolving concept that requires a team approach amongst the surgeon, anesthesiologist, and operating room staff. An Anesthesia Alert raises awareness for possible complications during anesthesia induction as well as allocates resources to increase patient safety and avoid preoperative delays. Most importantly, this concept places the onus on the surgeon to alert the anesthesiologist for possible complications during induction and extubation.

Non-Operating Room Anesthesia and the COVID-19 Patient: Evidence Based Strategies

As non-operating room anesthesia (NORA) vastly increases, so does the complexity of both the patients and the procedures. Unfamiliar environment, remote locations, and limited access to resources are some of the many challenges faced by the anesthesiologist in this environment. Understanding the environmental factors such as the room layout, machine placement and patient positioning needs advanced planning in the COVID-19 patient to determine airway management, intravenous access and overall patient safety. Communication with the proceduralist and healthcare workers (HCW) is of essence as both the procedure and anesthetic requirements may need to be altered as the case progresses. Standard monitoring guidelines should apply to all patients regardless of depth of anesthesia. The COVID-19 patient adds to these challenges. Aerosol generating medical procedures (AGMP’s) need to be identified ahead of time in order to ensure the safety of both the staff and patients. This allows for planning and preparation required for transportation of the patient to the room. HCWs may need to be identified and be available to assist with the procedure. Time should be allocated for transportation, briefing, room preparation, personal protective equipment needs of the staff and donning and doffing procedures as per institutional protocol. Communication means with staff outside of the room should be discussed in advance should an emergent situation arise during the procedure. Debriefing should be performed at the end of every procedure to improve patient safety and outcomes.
