Development, Delivery and Evaluation of a Safety Training Program on Demolition for Blight Reduction

The main objective of the work presented in this paper was to develop a customized safety training program that can be incorporated into the demolition projects undertaken as part of blight reduction efforts in urban centers. A subsidiary objective was to devise and implement a safety program evaluation methodology, and gain insights on the relationships between knowledge acquisition through training and trainee demographics. Salient aspects of blight elimination efforts, as well as the main facets of building demolition practices and requirements, were reviewed. Information on various related safety and health hazards was studied in depth with a focus on demolition operations dealing with blighted properties. A unique safety hazard awareness training program was created for demolition workers, contractors and inspectors based on this research. In addition to devising a curriculum of relevant training topics along with traditional and online delivery systems to be employed, effectiveness evaluation instruments were formulated. Based on the limited data collected from the trainees it was concluded that the program was well-received by them and provided effective learning. It was also found that no statistically significant associations existed between the knowledge gain of the trainees, and either their experience level or union status, after taking this training.

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.

Application of Optical Motion Capture Technology in Power Safety Entitative Simulation Training System

The safety production is critical to stable development of Chinese electric power industry. With the development of electric power enterprises, the requirements of its employees are also becoming higher and higher. In this paper, an optical motion capture system based on the virtual reality technology is proposed to meet the requirements of the power enterprise for the qualified business ability. Electric power equipment, power equipment model entitative operating environment and the human model are established by electric power simulation unit, ZigBee technology and OpenGL graphics library. The problem of missing feature points is solved by applying the human model driven algorithm and the Kalman filtering algorithm. The experimental results show that it is more accurate to use Kalman filtering algorithm to extract the feature point in tracking process of actual motion capture and real-time animation display. The average absolute error of 3D coordinates is 1.61 mm and the average relative error is 2.23%. The system can improve trainees’ sense of experience and immersion.

Practice,training and safety of laparoscopic surgery in low and middle-income countries

Surgical management of diseases is recognised as a major unmet need in low and middle-income countries(LMICs). Laparoscopic surgery has been present since the 1980 s and offers the benefit of minimising the morbidity and potential mortality associated with laparotomies. Laparotomies are often carried out in LMICs for diagnosis and management, due to lack of radiological investigative and intervention options. The use of laparoscopy for diagnosis and treatment is globally variable, with highincome countries using laparoscopy routinely compared with LMICs. The specific advantages of minimally invasive surgery such as lower surgical site infections and earlier return to work are of great benefit for patients in LMICs, as time lost not working could result in a family not being able to sustain themselves. Laparoscopic surgery and training is not cheap. Cost is a major barrier to healthcare access for a significant population in LMICs. Therefore, cost is usually seen as a major barrier for laparoscopic surgery to be integrated into routine practice in LMICs. The aim of this review is to focus on the practice, training and safety of laparoscopic surgery in LMICs. In addition it highlights the barriers to progress in adopting laparoscopic surgery in LMICs and how to address them.

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

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.

Dynamic simulation and safety evaluation of high-speed trains meeting in open air

Dynamic responses of a carriage under excitation with the German high-speed low-interference track spectrum together with the air pressure pulse generated as high-speed trains passing each other are investigated with a multi-body dynamics method.The variations of degrees of freedom（DOFs：horizontal movement,roll angle,and yaw angle）,the lateral wheel-rail force,the derailment coefficient and the rate of wheel load reduction with time when two carriages meet in open air are obtained and compared with the results of a single train travelling at specifie speeds.Results show that the rate of wheel load reduction increases with the increase of train speed and meets some safety standard at a certain speed,but exceeding the value of the rate of wheel load reduction does not necessarily mean derailment.The evaluation standard of the rate of wheel load reduction is somewhat conservative and may be loosened.The pressure pulse has significan effects on the train DOFs,and the evaluations of these safety indexes are strongly suggested in practice.The pressure pulse has a limited effect on the derailment coefficien and the lateral wheel-rail force,and,thus,their further evaluations may be not necessary.

Endoscopic non-technical skills team training:The next step in quality assurance of endoscopy training

AIM:To investigate whether novel,non-technical skills training for Bowel Cancer Screening(BCS)endoscopy teams enhanced patient safety knowledge and attitudes.METHODS:A novel endoscopy team training intervention for BCS teams was developed and evaluated as a pre-post intervention study.Four multi-disciplinary BCS teams constituting BCS endoscopist(s),specialist screening practitioners,endoscopy nurses and administrative staff(A)from English BCS training centres participated.No patients were involved in this study.Expert multidisciplinary faculty delivered a single day’s training utilising real clinical examples.Pre and post-course evaluationcomprised participants’patient safety awareness,attitudes,and knowledge.Global course evaluations were also collected.RESULTS:Twenty-three participants attended and their patient safety knowledge improved significantly from43%-55%(P≤0.001)following the training intervention.12/41(29%)of the safety attitudes items significantly improved in the areas of perceived patient safety knowledge and awareness.The remaining safety attitude items:perceived influence on patient safety,attitudes towards error management,error management actions and personal views following an error were unchanged following training.Both qualitative and quantitative global course evaluations were positive:21/23(91%)participants strongly agreed/agreed that they were satisfied with the course.Qualitative evaluation included mandating such training for endoscopy teams outside BCS and incorporating team training within wider endoscopy training.Limitations of the study include no measure of increased patient safety in clinical practice following training.CONCLUSION:A novel comprehensive training package addressing patient safety,non-technical skills and adverse event analysis was successful in improving multi-disciplinary teams’knowledge and safety attitudes.

Best Practice Standards and Methodology for Crane Operator Training—A Global Perspective

Crane operators control mobile or stationary cranes to lift, move and place objects at locations such as building and construction sites, wharves and shipyards. This activity occurs all over the world and is a high risk task with many noted examples of serious incidents and accidents. There are identifiable key causes that have been noted through analysis of the well documented cases and many of these causes are preventable through effective training programs. Internationally, there are not currently consistent approaches to crane operator training program content or duration. Leading causes of crane accidents are firstly discussed and identified as areas for inclusion in training programs. A number of current training approaches from a range of countries are then considered and these are used to outline the basis of a generic competency standard for crane operation, as it was found that there are not common standards in place. The proposed competency standard can be adapted by training regulators, training providers, government agencies, industry bodies and enterprises as a benchmark for the development of effective training programs.
