Identification of problems of professional training of state civil servants on the basis of analysis of features of programs of additional professional education

Problem and purpose. The growth of geopolitical tension in modern conditions concerns all states of the world. The civil service, by definition, should identify, organise and implement all possible methods, ways and means for the development of the state as a whole, qualitative improvement of the state's position in the international arena. The complexity of the tasks to be solved, the variety of functions performed by the specialists of the state civil service, requires an understanding of the extent to which programmes for the training of state civil servants modern requirements and methodology of additional professional education, the priorities of the state civil service and the personal needs of students. Purpose of the study: to identify the problems of training of state civil servants in the process of implementation of programmes of additional professional education. Materials and methods. The research was based on the method of content analysis of VET educational programmes presented in the Federal Register of training for civil servants. 121 programmes of thirteen educational organisations were analysed with regard to priority areas. The data obtained in the course of the study were analysed using the following methods: intellectual analysis, cluster analysis, descriptive statistics, contextual analysis, graphical analysis. Results of the study. The study revealed the features of the implementation of additional professional education programmes in the civil service: in the period from 2021 to the first quarter of 2024, there was a trend towards an increase in the number of educational institutions submitting educational programmes to the federal register. 2024 there is a tendency to increase the number of educational institutions that submit educational programmes to the federal register. The formats of training are expanding. The analysis of the subject matter of programmes has shown their imbalance, their share varies from 4.5% to 38.6%. Conclusion. The heterogeneity of approaches to the structuring of VET programmes in different educational organisations makes it difficult to objectively assess their quality and can disorient and demotivate civil servants in choosing the relevant and necessary programme.

A Training-of-Trainers program for health facilitators fighting malaria in a vulnerable community

Abstract Background When Public Health is challenged by issues related to migrant and vulnerable populations, health facilitators’ profiles are crucial to accessing communities and increasing intervention effectiveness and acceptability. The French overseas region, French Guiana, is concerned with a migrant population living in vulnerable conditions far from healthcare and being a major reservoir of malaria. Curema is an intervention implemented to fight malaria in this population by distributing RDTs, and treatments after an appropriate training of participants. Facilitators from the community are employed to provide health education and enroll participants. Objectives An intensive theoretical-practical training program was realized to enable facilitators to master procedures related to the intervention. The training was designed using the CDC Training-of-Trainers (ToT) framework and adult learning principles. It was composed of initial and on-the-field training, both based on bidirectional, participative, and dynamic working spaces. A mixed-method evaluation was carried out to assess training effectiveness and quality. Results Group dynamics and adaptations driven by facilitators’ needs were key elements of a high-quality training program. Satisfaction was elevated for training format and learning results. Statistically significant improvements in knowledge level demonstrated good effectiveness. During the initial training, difficulties persisted regarding some tasks to be performed during the intervention: further on-the-job training addressed them, improving facilitators’ practices in the field. Conclusions High-quality, effective, and appropriate training programs are required for intervention involving facilitators’ profiles. Training design is crucial to achieve it. ToT model has been shown to allow high satisfaction, learning results, and good implementation in the field. Initial and on-the-job training are an indispensable continuum to sustain good practices and motivation. Key messages • If health facilitators from the community are actors in public health interventions, appropriate training is necessary to ensure good implementation. • ToT seems an optimal model for training health facilitators.

Enhancing port preparedness in Germany in the event of infectious diseases – a best practice study

Abstract Background The maritime sector is exposed to specific risks in the area of communicable diseases. In Germany, five ports are designated to enforce the International Health Regulations (IHR) and must have certain core capacities to respond immediately to cross-border health threats. A joint external evaluation conducted by the World Health Organization (WHO) revealed a need to reinforce central structures in Germany. The overarching objective of the study is to harmonize and consolidate the requisite capacities for maritime health security. Methods Qualitative interviews (n = 35) at baseline were conducted with various stakeholders, including port medical services, port authorities and other stakeholders. The parameters to be analysed included specific activities and interfaces during infectious incidents, experience with past infection incidents, training and exercise, and the need for action. Furthermore, a document analysis was conducted, during which the existing contingency plans and standard operating procedures were reviewed. Results In essence, the initial challenges posed by the COVID-19 pandemic have led to the establishment of well-defined procedures and interfaces between the various stakeholders involved. There is a necessity for enhanced interpersonal communication between the various stakeholders and the implementation of sustainable training practices. Furthermore, greater transparency and standardisation of regulations in international health emergencies is desired. Conclusions Given the infrequency of cross-border infection incidents on board ships, targeted preparation within stakeholders is often given a lower priority than other work priorities. The participatory study design is intended to develop comprehensive concepts in collaboration with the IHR ports in the ongoing project. Subsequently, these concepts will be tested in tabletop exercises and incorporated into training formats for public health actors. Key messages • The qualitative interview study at baseline revealed a substantial need for sustained communication and training practices among stakeholders for infectious disease preparedness in German IHR ports. • The document analysis revealed relevant differences in the extent and scope of contingency plans of German ports designated under the International Health Regulations.

Informing factors and outcomes of self-assessment practices in medical education: a systematic review

Background Self-assessment (SA) is increasingly recognized not only as an assessment method but also as a vital learning activity that enables learners to identify their strengths and limitations, fostering a crucial skill for lifelong learning. Despite its acknowledged significance, there remains a gap in understanding SA for and as learning, rather than merely of learning. This review, therefore, explores two primary questions: (1) What factors inform the implementation of medical students’ SA practices? (2) How does SA practices contribute to various educational outcomes? Methods A systematic review was conducted across five databases, employing a combination of keywords pertinent to SA and medical education. Our selection criteria deliberately excluded articles that solely focused on the accuracy of SA or used SA exclusively as a measure for other outcome variables. As a result, 39 studies met our inclusion criteria and were analyzed for this review. Qualitative narrative synthesis was used to summarize the informing factors. Furthermore, Kirkpatrick’s model was employed to categorize and summarize the effects of SA activities across various educational outcome levels, including reactions, learning, and behavioral changes. Results Our review reveals that key factors influencing students’ SA includes feedback from various stakeholders, peer assessment, the format of SA, and both learner and teacher training. Among the 39 studies examined, the majority demonstrated positive effects of SA on aspects such as attitudes and skills. However, a minority found no significant associations, with these outcomes frequently linked to contextual variables and how SA was implemented. Conclusions Our review does not focus on SA accuracy or its role as an assessment method; instead it delves into the role of SA as an integral learning practice. We explored its influencing factors and its impact across various outcomes. The findings indicate that for SA to effectively enhance student learning outcomes, it must be implemented with ample support, clear guidelines, and within contexts that encourage feedback and reflection.

Modern aspects of pathology teaching

Introduction. Undergraduate medical curricula often fail to balance learning opportunities and integrate the study of basic and clinical sciences, allowing students to link theory and practice. The high educational potential of the experimental teaching method is due not only to its practical orientation but also to the possibility of reflection - critical analysis and synthesis of knowledge in the learning process.Aim of the study. Evaluate the possibility of introducing experiential learning in the study of pathology to improve the efficiency of students' perception of understanding the subject and subsequent application in clinical practice.Materials and methods. The study sample (n=362) consisted of 3rd year students of NAO «Karaganda Medical University», studying in the disciplines: «General pathology» and «Pathology of organs and systems» in the 2022-2023 academic year. The sample included 48.9% male and 51.1% female students aged 19 to 22. Respondents were divided into a main group (n=96) using an experimental training method and a control group (n=266) using a traditional training format. A specially designed questionnaire was used to study student satisfaction with training. Descriptive statistics methods were used to describe the assessments of students in the study groups. Thematic analysis was used to examine the data collected using open-ended questions.Results. The possibility of interaction and discussion with the teacher during the joint viewing of micropreparations of the studied cases was rated as «excellent» by 95.8% and 97.9% of students. With regard to the main characteristics of medical education in the study of pathology, four broad topics are verified, such as fundamental medical education, interaction with the teacher in obtaining medical education, teaching materials in medical education, and assessment in the field of medical education. The study used methods of descriptive statistics. Thematic analysis was used to process data collected using open-ended questions.Discussion. The high level of acceptance of interactive groups in the study of pathology and the general satisfaction of students reflect the desire and need for active teaching methodologies in modern medical education.Conclusion. Based on the findings, the practical teaching of pathology can be improved by revisiting the content and teaching strategies.

Implementing LEARN: Comprehensive Suicide Prevention Training for High School Students, Parents, and School Personnel.

Adolescent suicide is a public health issue, and school is an ideal setting for prevention activities. LEARN is a peer-led gatekeeper training for high school personnel, parents, and students. The purpose of this study was to evaluate the effectiveness of LEARN as a gatekeeper training. Paired t tests were used to compare pre- and post-training surveys for 4983 LEARN participants. Participants reported an increased likelihood of engaging in each LEARN step: looking for signs, empathizing and listening, asking about suicide thoughts and plans, reducing danger, and connecting the person with help. Most participants were highly satisfied with the peer trainer's delivery of content. LEARN gatekeeper training was successfully implemented in high schools with students, parents, and school personnel. All groups reported increases in likelihood of approaching and providing support and connections for at-risk individuals and rated the trainer as effective, indicating satisfaction with the peer-led training format.

TetraFEM: Numerical Solution of Partial Differential Equations Using Tensor Train Finite Element Method

In this paper, we present a methodology for the numerical solving of partial differential equations in 2D geometries with piecewise smooth boundaries via finite element method (FEM) using a Quantized Tensor Train (QTT) format. During the calculations, all the operators and data are assembled and represented in a compressed tensor format. We introduce an efficient assembly procedure of FEM matrices in the QTT format for curvilinear domains. The features of our approach include efficiency in terms of memory consumption and potential expansion to quantum computers. We demonstrate the correctness and advantages of the method by solving a number of problems, including nonlinear incompressible Navier–Stokes flow, in differently shaped domains.

Autism Training for Law Enforcement Officers: Perceptions From the Field.

Autistic individuals and law enforcement officers are likely to engage under various circumstances within the community. Therefore, law enforcement officers require training on supporting those with autism and better understanding autistic behaviors. Aims for this study include: (1) developing and delivering high quality professional development on autism spectrum disorder (ASD) to support autistic individuals during encounters with law enforcement officers, and (2) examining how law enforcement officers respond to the professional development session. For this study a four-hour, in-person training on autism for law enforcement officers was developed. Law enforcement officers (n = 27) attended the training session. Subsequently, participants completed an open-ended survey gathering perceptions related to the topics covered in the training, thoughts on the feasibility and applicability of content, and transfer to future safety encounters involving autistic individuals. Data was analyzed using a qualitative approach including concept driven thematic coding with constant comparisons. Data yielded themes on experiences with the autistic community, strategies learned from the training, thoughts on specific content, and feedback on the training format. Overall, law enforcement officers reported they felt better prepared, more knowledgeable on the autistic community, and believed the strategies were feasible and applicable to the field. These findings point to the importance of training on autism and that law enforcement officers found it was time well spent. Future directions include examining how training transfers to practice in the field and ways to connect law enforcement officers with the autistic community outside of emergency response.

Building the clinical workforce of pediatric infectious diseases in Bolivia for better care of children with cancer

Abstract Background Infections in children with cancer can be fatal if not appropriately managed. Access to trained and competent professionals in infection care and prevention (IC&P) improve care outcomes. Bolivia expects about 1700 new pediatric cancer cases annually. In 2023, 2371 hematological neoplasms were reported in children, cared mainly at 4 public hospitals where, until 2016, 5 pediatric infectious disease (PID) specialists were working in 2 of these 4 hospitals. For better PID clinical workforce for critically ill children, we built a PID medical residency training. In 2017, the training accepted its first trainees at Hospital del Niño “Dr. Ovidio Aliaga Uría” (Hospital del Niño), a public hospital in La Paz. Here, we describe the program, how we built it, and its outcomes. Methods The PID training goal is to train leaders in PID for clinical observations, PID literature interpretation, and to transform them into concepts that can be applied to ID pathogenesis or treatment. At the end of the 2-year PID training program, we expect trainees will gain expertise in PID clinical practice and clinical or translational science research. Our PID program was based on other PID specialty training programs from Mexico, Spain, and the USA of which, we adapted standard topics and formats of training. The content has routine and prevalent PIDs of Bolivia and the region, including on immunocompromised patients. We expected that the trainee dedicate full time to the PID training program plus caring for assigned patients and those requested consultations in the wards and clinics of Hospital del Niño; review articles; participate in clinical discussions; attend the Infection Control Course of St. Jude Children’s Research Hospital; attend and / or present in the PID case-based learning international sessions; visit the virology, bacteriology, parasitology and immunology laboratories of the national reference laboratory; and attend international rotations at participating hospitals. Results Since 2017, 5 new PID pediatricians graduated from our program, 3 work in public hospitals that care for children with cancer and 2 work in government insurance hospitals. They are working in hospitals in La Paz (n=2), Cochabamba (n=1), Santa Cruz (n=1), and Tarija (n=1). These graduates are leaders in ICP, antimicrobial stewardships, and education of hospital staffs. As per December 2023, they produced 5 articles for local journals, 2 for international journals, 7 abstracts for scientific meetings. Currently, 2 pediatricians participate in the PID training program, and post-graduation, they plan to work in departments of Potosí and Sucre where there are no PID specialists. Challenges to establish PID specialists in Bolivia are lack of value attributed to PID and its role in care quality. Conclusion Creating local expertise in PID are essential to improve and sustain the optimum care for children with cancer in Bolivia especially in places where these personnel did not exist before. However, for best investment return of PID trained professionals, having PID job descriptions and paid positions in hospitals will absorb PID specialists to benefit the largest population of children with cancer in Bolivia.

Breaking the Silence: Addressing Domestic Abuse in Mental Health Settings-Identification, Screening, and Responding.

Individuals experiencing domestic abuse (DA) struggle to disclose victimization, but as frequent users of mental health services, this is a pivotal setting for identification and addressing DA. This systematic review of 20 studies investigates DA identification, screening, and responses within mental health settings. Three databases were searched using these inclusion criteria: adults aged 18 and older accessing mental health services, samples comprising mental health professionals (or combination). No geographical restrictions were applied. All studies were peer-reviewed and published in English between January 2000 and December 2023. Studies had to incorporate screening for DA between (ex-)partners and/or response to disclosure within mental health settings. The findings revealed considerable variation in DA screening methods from direct screening tools to retrospective analyses of patient files. Professionals report barriers in identifying DA, including uncertainty about their role, time constraints, and the importance of building trust with service users. Nonetheless, many highlight the importance of routinely asking about DA. A small number of interventions have been effective in enhancing professionals' readiness to address DA, but it remains unclear what format of training is most effective. Service users report feelings of shame and fear of not being believed when disclosing DA, but are aided by therapeutic engagement and enhanced professional awareness. There is a lack of diverse inclusion in the research. In summary, there is considerable scope to develop good practice to support mental health professionals' ability to identify and respond to DA across assessment tool and training, but also in understanding what facilitates service users to disclose.

Annual Training Program in Radiological Protection in a Radiotherapy Service – A Case Study

The safety and radiological protection in radiotherapy services are essential to ensure the safe use of ionizing radiation for the benefit of patients and involved professionals. Evaluative research on multidisciplinary teams regarding annual training in radiological protection in radiotherapy is scarce. It is crucial to understand how professionals from each area assess the acquired knowledge and apply theoretical precepts in the radiotherapy service. This study aimed to analyze the annual radiological protection training offered in a radiotherapy service, and as specific objectives, to map the knowledge of professionals from each area regarding radiological protection applied during training. This is a qualitative research of the case study type. Data collection occurred through semi-structured interviews, simple observation, and documentary analysis, organized in the ATLAS.ti software version 24. The results indicate significant challenges, including the lack of understanding of basic principles by professionals, the absence of integration between the team and supervisors, and the lack of clear definition of the training format in current regulations. The results were categorized into: professionals' knowledge of radiological protection; training weaknesses; training strengths; suggestions for training delivery methods and topics in radiological protection. More effective educational strategies, along with precise guidance on the training format, emerge as promising solutions to overcome these challenges.

Distributed Global Composite Learning Cooperative Control of Virtually Coupled Heavy Haul Train Formations

Space–time collision avoidance and train dynamics constraints-driven optimal control for heterogeneous heavy-haul trains platoon operation considering air brake delay

The potential of heavy-haul train platoon operation technology in improving railway freight capacity is increasingly recognised, with extensive trial research currently underway. This study firstly utilising longitudinal train dynamics devised a space–time collaborative collision avoidance model for trainsets, accounting for air brake delay. Secondly, an air brake application strategy was proposed, focusing on collision avoidance and managing speeds on steep ramps. Subsequently, a constraint-driven optimal control scheme tailored for heavy-haul train platooning operations within an open railway environment was developed, which simulates train platooning amidst real-world dynamic traffic flow scenarios, offering a global perspective on railway network operations. Finally, we comprehensively evaluate the impact of line conditions on key platoon control parameters based on realistic railway operation scenarios. Findings show that constraint-driven optimal control, integrating train dynamics and space–time collaborative collision avoidance, effectively replicates the dynamic traits of train platoons. The consideration of air braking delays is crucial due to heterogeneous train formations and steep ramps, which can easily cause collisions. Moreover, on real-world railway lines, the average headway of heavy-haul trains weighing 10,000 tons and below can be compressed to 99.82 s when operating in platoons, significantly enhancing transportation capacity compared to existing semi-automatic blocking systems.

Training approaches for the dissemination of clinical guidelines for NSSI: a quasi-experimental trial

BackgroundNon-suicidal self-injury (NSSI) is of high clinical relevance due to its high prevalence and negative long-term implications. In 2016, the German consensus-based clinical guidelines for diagnostic, assessment and treatment of NSSI in childhood and adolescence were published. However, research indicates that clinical guidelines are often poorly implemented in clinical practice. One crucial part of this process is the training of healthcare professionals to transfer knowledge and capacities to bring guideline recommendations into clinical practice.MethodsThe effect of three different dissemination strategies (printed educational material, e-learning, and blended-learning) on the NSSI guidelines´ recommendations was examined among 671 physicians and psychotherapists via an online-survey. The quasi-experimental study included three measurement points (before the training, after the training, 3-month follow-up) and mixed effects models were used to test for changes in knowledge, competences and attitudes toward NSSI and treatment. Moreover, the transfer of gained competences to practical work and user satisfaction were reviewed.ResultsWith all three training formats, the intended changes of the outcome variables could be observed. Hereby, the printed educational material condition showed the lowest improvement in the scores for the ‘negative attitudes toward NSSI and those who self-injure’. The training effect remained stable throughout the follow-up measurement. The highest application rate of acquired intervention techniques in clinical practice was reported for the blended-learning condition. For all three training strategies, user satisfaction was high and evaluation of training quality was positive, with printed educational material receiving the lowest and blended-learning the highest evaluations.ConclusionsIn summary, all three training formats were perceived to be of high quality and seem to be suited to cover the needs of a heterogeneous group of physicians and psychotherapists. The choice of training method could be driven by considering which training goals are desired to be achieved and by the benefit-cost ratio allowing for tailored training approaches.

A training protocol compliance of 13% was observed in a research study of clinical research professionals

ObjectiveWe attempted to conduct a randomized controlled trial of three different informed consent training formats to evaluate their effectiveness. We recruited 503 clinical research professionals, who received $50 for participation. Incidental findings showed unexpectedly low rates of compliance with completing the study training protocols, resulting in insufficient statistical power to test our original hypotheses. In this report, we conducted a secondary analysis of the data in which we characterize and evaluate the observed low compliance. This involved using literature on average reading times, speed-reading times, and video play speeds to calculate the timeframes required to complete the three training formats.ResultsOnly 13% of participants completed the training in a reasonable timeframe. Furthermore, only 46% of participants completed the training in the minimum possible timeframe. These findings lead us to ask whether online research training is effective, since no training can be effective if participants do not actually complete the training. Given extensive requirements for educational training among clinical research professionals, we feel the burden of proof is on training programs to demonstrate that they have positive effects.

The Effect of Velocity-Based Contraction Strength Training on Performance in Female 400m Athletes

This study aims to compare the differences in strength training at velocity of muscle contraction in 400-meter runners. The sample group consisted of 12 female athletes who participated in the Thailand National Sports competition qualifiers in 2023. The group was divided into two: the first group underwent strength training at a fast muscle contraction rate with 80 bpm, while the second group trained at a normal muscle contraction rate with 40 bpm. The training lasted for 8 weeks, and after a 2-week post-training period, both groups were tested by swapping strength training programs. They were tested for 400-meter speed, strength from finding the 1 RM of Leg curl, Leg extension, and Leg press measured in kilograms, and explosive power from Squat jump, Countermovement jump, and Long jump. The data collected was analyzed to find the average, standard deviation, and one-way ANOVA with a statistical significance level set at .05. From the research's results, it was found that percentage change muscle contraction rates differs significantly between the two strength training formats: one with fast muscle contraction and the other with normal- muscle contraction rate (1.04±0.02 and 1.02±0.02, respectively) at a significance level of .05. Additionally, the strength and explosive power percentage change also significantly differ between the two strength training formats. Therefore, based on this study, it is possible to utilize the fast muscle contraction rate strength training format to enhance the athletic performance of athletes.

The Effects of Volume-Matched 1- and 2-Day Repeated Backward Sprint Training Formats on Physical Performance in Youth Male Soccer Players.

Bouguezzi, R, Negra, Y, Sammoud, S, Uthoff, A, Moran, J, Behrens, M, and Chaabene, H. The effects of volume-matched 1- and 2-day repeated backward sprint training formats on physical performance in youth male soccer players. J Strength Cond Res XX(X): 000-000, 2024-This study examined the effects of a 6-week, 1 vs. 2 sessions of volume-matched weekly repeated backward sprint training (RBST) on measures of physical fitness in youth male soccer players. Thirty male youth soccer players from a regional soccer team were randomly assigned to a 2-day group (n = 15; age = 16.40 ± 0.64 years; Maturity-offset = 2.19 ± 0.65 years) or a 1-day group (n = 15; age = 16.27 ± 0.51 years; Maturity-offset = 1.91 ± 0.40 years). Measures of jumping ability, linear sprint speed, change-of-direction (CoD) speed, aerobic endurance (AE), and repeated sprint ability (RSA) were measured before and after 6 weeks of training. The training interventions involved 1 to 2 sets, each comprising 7 repetitions over a 20-m distance of RBST in the 2-day group, and 2 to 4 sets, also with 7 repetitions each over the same distance, in the 1-day group. Statistical analyses were conducted using the analysis of covariance model with baseline measurements entered as covariates. Results indicated that RBST over 2 days generated greater benefits compared with a single day for improving CoD speed (∆4.91 vs. 0.04%; effect size [d] = 0.78 vs. 0.00, respectively), linear sprint speed (10-m: ∆4.74 vs. 0.36%; d = 0.96 vs. 0.00, respectively; 20 m: ∆3.34 vs. 0.82%; d = 1.00 vs. 0.49, respectively), and RSA performances (RSAbest: ∆2.61 vs. 0.29%; d = 0.71 vs. 0.16, respectively; RSAmean: ∆2.86 vs. 0.89%; d = 0.59 vs. 0.16, respectively; RSAtotal: ∆2.86 vs. 0.89%; d = 0.62 vs. 0.41, respectively). However, similar improvements in the 2 RBST formats were observed on jumping (2-day group: ∆6.9%; d = 0.75; 1-day group: ∆10.6%, d = 1.26) and AE performance (2-day group: ∆17.24%, d = 1.04; 1-day group: ∆27.25%, d = 2.25). In summary, the findings suggest that, when volume is matched, spreading the RBST regimen over 2 days may result in greater improvements compared with a single-day approach for enhancing CoD speed, linear sprint speed, and RSA performance.

Comparing the Efficacy of Endovascular Simulation Training in Different Training Formats: A Randomized Controlled Trial

High-fidelity endovascular simulators have demonstrated significant potential in enhancing interventionalists' performance metrics, including procedure time (PT), fluoroscopy time (FT), and contrast volume (CV) usage. However, it is less clear whether trainee performance, when assessed using both multidimensional global and procedure-specific rating scales (PSRS), improves in a manner consistent with these metric parameters. This study aimed to determine whether the structure of the training-conducted in block sessions or weekly intervals-impacts the effectiveness of the training. Twenty students were enrolled in this prospective, randomized, controlled, single-center trial. They were randomly divided into block and weekly training groups, each undergoing 6hrs of supervised endovascular training on a Mentice simulator over a span of 3weeks. At the outset and conclusion of their training, students performed a predefined peripheral endovascular intervention, which was assessed by an experienced interventionalist. Furthermore, participants were prompted to complete a survey at both the beginning and the end of the study. Both groups exhibited significant improvements in PT, FT, CV usage, global rating scale (GRS) scores, and performance-specific rating scale scores. However, no significant difference was observed between the 2 groups. The simulator training notably boosted the trainee's self-confidence. Simulator training not only enhances metric performance parameters but also improves performance as assessed by both GRS and PSRS. Whether the training is conducted in block sessions or weekly intervals did not affect its efficacy. As such, the training format can be tailored to best fit the specific circumstances and setting.

Impact of Train Formation on the Dynamic Responses and Operational Safety of High-Speed Trains under Non-Uniform Seismic Ground Motion

The study of dynamic responses and operational safety of high-speed trains under seismic excitation has increasingly relied on numerical simulation as the most effective and convenient research approach. The majority of studies only focus on single-car formation, and fewer utilize train models with actual standard formation, inevitably resulting in differences in dynamic characteristics of train models and simulation results. Furthermore, trains also have different standard formations in different countries and operating scenarios. Therefore, the influences of train formation on the dynamic responses and operational safety of trains under seismic action are investigated. Hence, a detailed train/vehicle–track coupled dynamics model was established to simulate trains under non-uniform seismic ground motion. Moreover, due to wheel–rail contact simulation being the key factor constraining simulation efficiency, based on the influence pattern of train formation, whether fewer train formations can achieve the same simulation accuracy as the 8-car standard formation is also explored in this paper considering seismic wave propagation effect. Results indicate that variation in train formation can influence the dynamic responses of a coupled system significantly from both the perspective of wheel–rail interaction and vehicle kinematic responses. Moreover, the 5-car formation model can better meet the accuracy requirement and significantly improve computational efficiency compared to 8-car formation model.
