The construction of canine distal limb models used in teaching sonography identification of vegetal foreign bodies.

Musculoskeletal ultrasonography is a useful tool to identify radiolucent vegetal foreign bodies (VFBs). However, limited ultrasound experience and unfamiliarity with the normal sonographic appearance of anatomical structures can decrease clinician confidence. This study aimed to design a reusable silicone model that can teach VFB identification within the canine distal limb. Four canine hindlimbs were used to design the silicone models, and 12 canine distal forelimbs were constructed. The model was constructed using cadaver bones, barley grass (Avena fatua) seeds, and silicone to mimic the anatomy of the canine distal limb with a grass seed VFB. Limbs were randomly grouped based on grass seed locations: (1) the interdigital webbing, (2) the palmar surface of the canine forelimb immediately proximal to the metacarpal pad, (3) the dorsal surface of the distal limb immediately proximal to the proximal phalange, or (4) no grass seed (control) placed. Each limb was systematically ultrasounded and compared with cadaver limbs and clinical VFB cases. A comparison of ultrasonographic images validated the construction, revealing that the simulation model replicates the anatomical and echotexture characteristics of the normal canine distal limb. Furthermore, these models also have a likeness to clinical canine distal limb VFB cases and can be utilized as a training tool.

308 Awardee Talk: Prevention and mitigation of pathogens in feed and feed manufacturing systems

Abstract Prior to 2013, pathogen transmission through feed was focused primarily on bacteria and biosecurity was used to prevent adulterant entry into the ingredients and the feed mills. Following the porcine epidemic diarrhea virus (PEDV) outbreak in 2013, research focused on pathogen mitigation and control quickly became a subject of interest. Since PEDV, multiple endemic viruses and foreign animal diseases have been found to be transmissible in feed or feed ingredients. As African swine fever virus (ASFV) spread closer to the United States and endemic pathogens are a continued pressure on production systems, it is imperative that prevention measures are included in the feed supply chain and options for mitigation are fully elucidated for times of need. Previous research has demonstrated that preventative measures such as boot baths, lines of separation, showers, and changing clothes are effective measures when appropriately maintained. However, these protocols can seem costly and burdensome to employees, especially when the risk of disease transmission appears low. Employee training is difficult as disease transmission is difficult to visualize and exhibit the importance of each measure. Glo Germ, a florescent substance, is a cost-effective training tool which can demonstrate the efficacy of prevention protocols and can identify areas where biosecurity measures have not been properly utilized. Preventative measures are the first line of defense for feed manufacturing systems, but understanding and using mitigation techniques in the event of contamination can limit pathogen spread and protect the rest of the feed supply chain. Pelleting, as a method of thermal inactivation process, has recently been demonstrated to lessen the quantity of detectable viral RNA and decrease the risk of infection. The pelleting process, however, is a point-in-time mitigant and does not decrease the risk of product re-contamination as feed continues down the supply chain. The use of chemical mitigants, like formaldehyde, medium-chain fatty acids, and organic acids, can decrease the presence of bacterial and viral pathogens with longer-lasting mitigation properties. These mitigants can either be used in the feed itself, or as an addition to flushing batches which help disperse the chemical mitigants throughout the feed manufacturing equipment, thus reducing the risk of product re-contamination. In the event more drastic measures must be taken to eliminate pathogen presence from feed mills, gaseous fumigation and the use of portable heaters show promise as methods to decontaminate feed manufacturing equipment without the use of water or complete equipment breakdown. Overall, effective training and implementation of preventative measures are needed to provide pathogen-free feed to production systems, but continued research in mitigation and mill decontamination will further protect the feed supply chain in the event of pathogen contamination.

Acceptability and feasibility of screening with a pediatric care provider-led social determinants of health identification tool

BackgroundComplex social determinants of health may not be easily recognized by health care providers and pose a unique challenge in the vulnerable pediatric population where patients may not be able to advocate for themselves. The goal of this study was to examine the acceptability and feasibility of health care providers using an integrated brief pediatric screening tool in primary care and hospital settings.MethodsThe framework of the Child and Adolescent Needs and Strengths (CANS) and Pediatric Intermed tools was used to inform the selection of items for the 9-item Child and Adolescent Needs and Strengths-Pediatric Complexity Indicator (CANS-PCI). The tool consisted of three domains: biological, psychological, and social. Semi-structured interviews were conducted with health care providers in pediatric medical facilities in Ottawa, Canada. A low inference and iterative thematic synthesis approach was used to analyze the qualitative interview data specific to acceptability and feasibility.ResultsThirteen health care providers participated in interviews. Six overarching themes were identified: acceptability, logistics, feasibility, pros/cons, risk, and privacy. Overall, participants agreed that a routine, trained provider-led pediatric tool for the screening of social determinants of health is important (n = 10, 76.9%), acceptable (n = 11; 84.6%), and feasible (n = 7, 53.8%).InterpretationThough the importance of social determinants of health are widely recognized, there are limited systematic methods of assessing, describing, and communicating amongst health care providers about the biomedical and psychosocial complexities of pediatric patients. Based on this study’s findings, implementation of a brief provider-led screening tool into pediatric care practices may contribute to this gap.

A reduced kinetic method for investigating non-local ion heat transport in ideal multi-species plasmas

Abstract A reduced kinetic method (RKM) with a first-principle collision operator is introduced in a 1D2V planar geometry and implemented in a computationally inexpensive code to investigate non-local ion heat transport in multi-species plasmas. The RKM successfully reproduces local results for multi-species ion systems and the important features expected to arise due to non-local effects on the heat flux are captured. In addition to this, novel features associated with multi-species, as opposed to single species, case are found. Effects of non-locality on the heat flux are investigated in mass and charge symmetric and asymmetric ion mixtures with temperature, pressure, and concentration gradients. In particular, the enthalpy flux associated with diffusion is found to be insensitive to sharp pressure and concentration gradients, increasing its significance in comparison to the conductive heat flux driven by temperature gradients in non-local scenarios. The RKM code can be used for investigating other kinetic and non-local effects in a broader plasma physics context. Due to its relatively low computational cost it can also serve as a practical non-local ion heat flux closure in
hydrodynamic simulations or as a training tool for machine learning surrogates.

Training in Endoscopic Endonasal Neurosurgical Procedures: a Systematic Review of Available Models

Background Proficiency in endoscopic endonasal neurosurgery (EEN) requires a unique skill set and is associated with a steep learning curve. Endoscopic simulation models present an opportunity for trainees to enhance their surgical skills and anatomical knowledge in a risk-free environment. To date, four main categories of training modalities have been recorded: cadaveric, synthetic, animal, and virtual reality (VR) models. Objective To analyze the features, advantages, and disadvantages of each EEN training model, describe the stages of simulation training, and propose future directions and an algorithm for EEN training. Methods A comprehensive search was performed including studies published before August 2023. Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were followed in the search and selection of studies included. Terms for searching title and abstract were (“simulation”)AND(“endoscopic endonasal”)AND(“neurosurgery”). Articles were screened for duplicates. Results We identified 176 references, and 43 studies met the inclusion criteria. Twelve articles described cadaveric models, with 7 of them studying internal carotid artery injury (ICAI) management and 3 of them CSF leak management; fourteen articles illustrated synthetic models, one article described animal models, and sixteen articles outlined virtual reality (VR) simulations. Conclusion Cadaveric models provide realistic hands-on surgical training with acceptable cost and remain the gold standard method for training. Synthetic models are most effective for preoperative surgical planning and animal models are best suited for testing of hemostatic techniques. VR simulations may become the primary training tool for novices to acquire basic anatomical knowledge as their role in advanced surgical planning is evolving.

Ductal Stenting in Low-Resource Environments.

Duct-dependent pulmonary circulation has traditionally been addressed by the Blalock-Taussig-Thomas shunts (BTTS). Recently, catheter-based alternatives such as ductal stenting have emerged as a particularly advantageous option, especially in resource-constrained settings. This article delves into the nuances of ductal stenting within low-resource environments, highlighting its relative ease of application, reduced morbidity, and cost-effectiveness as key factors in its favor. Comparisons in mortality between the two procedures are however likely to be confounded by selection biases. Ductal stenting appears to be particularly beneficial for palliating older infants and children with cyanotic congenital heart disease and diminished pulmonary blood flow who present late. Additionally, it serves as a valuable tool for left ventricular training in late-presenting transposition with an intact ventricular septum. A meticulous pre-procedure echocardiographic assessment of anatomy plays a pivotal role in planning access and hardware, with additional imaging seldom required for this purpose. The adaptation of adult coronary hardware has significantly enhanced the technical feasibility of ductal stenting. However, challenges such as low birth weight and sepsis specifically impact the performance of ductal stenting and patient recovery in low-resource environments. There is potential for systematic application of quality improvement processes to optimize immediate and long-term outcomes of ductal stenting. There is also a need to prospectively examine the application of ductal stenting in low-resource environments through multi-center registries.

Optimizing Strength Training Protocols in Young Females: A Comparative Study of Velocity-Based and Percentage-Based Training Programs

The purpose of this study was to compare the effects of velocity-based strength training (VBT) and percentage-based strength training (PBT) on absolute strength, explosive strength, speed, and agility, as well as markers of muscle damage after 6 weeks of exercise programs. The study included 30 young female individuals, divided into three groups of 10 participants: VBT, PBT, and control group. The main findings indicated that the VBT group and PBT group showed significant improvement in 1RM squat exercise (Δ% 27.87 and Δ% 8.98, respectively) and 1RM bench press (Δ% 14.47 and Δ% 8.65, respectively), but a greater enhancement was observed in the VBT group. In addition, VBT induced substantial changes in SJ (Δ% 14.32) and CMJ height (Δ% 7.69), while PBT had an improvement only in the SJ test (Δ% 6.72). The improvement noted in the VBT group could be attributed to its ability to tailor training intensity according to the speed of movement execution. This approach allows athletes to perform each repetition as fast as possible, thus maintaining an optimal intensity for explosive strength development. The capacity of VBT to adapt training intensity based on the speed of movement execution may be the key factor contributing to these results. Therefore, coaches and athletes should consider implementing VBT as a valuable tool to optimize strength and power development. In conclusion, VBT induced greater improvement in the 1RM squat, 1RM bench press, SJ, and CMJ compared to the group that performed the traditional strength training modality. Therefore, VBT is considered a more effective training tool regarding the development of absolute and explosive strength in young women.

LARLUS: laparoscopic augmented reality from laparoscopic ultrasound.

This research endeavors to improve tumor localization in minimally invasive surgeries, a challenging task primarily attributable to the absence of tactile feedback and limited visibility. The conventional solution uses laparoscopic ultrasound (LUS) which has a long learning curve and is operator-dependent. The proposed approach involves augmenting LUS images onto laparoscopic images to improve the surgeon's ability to estimate tumor and internal organ anatomy. This augmentation relies on LUS pose estimation and filtering. Experiments conducted with clinical data exhibit successful outcomes in both the registration and augmentation of LUS images onto laparoscopic images. Additionally, noteworthy results are observed in filtering, leading to reduced flickering in augmentations. The outcomes reveal promising results, suggesting the potential of LUS augmentation in surgical images to assist surgeons and serve as a training tool. We have used the LUS probe's shaft to disambiguate the rotational symmetry. However, in the long run, it would be desirable to find more convenient solutions.

Performance Evaluation of YOLOv5-based Custom Object Detection Model for Campus-Specific Scenario

This study evaluates the performance of a custom object detection model based on the YOLOv5 architecture, specifically tailored for autonomous electric vehicles. The model undergoes pre-processing using the Roboflow computer vision platform, which offers a wide range of tools for data pre-processing and model training. The experiments were conducted on a diverse dataset comprising various objects encountered in campus-specific driving scenarios, such as pedestrians, vehicles, buildings, and obstacles. The performance of the custom object detection model is assessed using standard metrics, including precision, recall, mean average precision (mAP), and intersection-over-union (IoU) at different thresholds. The training process was conducted in a controlled environment, resulting in a Precision of 0.851, a Recall of 0.831, and a mAP of 0.843. These metrics were analyzed to evaluate the YOLOv5-based custom object detection model's ability to detect and categorize objects accurately, its precision in predicting bounding boxes, and its capability to handle various object categories. We also examined the effects of different hyperparameters and data augmentation techniques on the model's performance, including variations in learning rate, batch size, and optimizer algorithms to determine their impact on accuracy and convergence. This analysis provided valuable insights into the model's strengths and weaknesses, highlighting areas for improvement and optimization. These findings are instrumental in developing and deploying advanced object detection systems to enhance the safety and reliability of autonomous electric vehicles.

Task Analysis in Human-Computer Interaction: A Comparison between Four Task Analysis Techniques

Task analysis is an integral part of human-computer interaction, as it permits the client to comprehend, complete, and benefit from the utilization of an interaction system. Task analysis methodologies differ based on the selected approach and the motivation behind its use. The present study aims to compare several task analysis methodologies (i.e. hierarchical task analysis, cognitive task analysis, GOMS task analysis, and emotion task analysis), initially outlining their commonalities and distinctions in structure and usability. After that, it will go into each technique's benefits and drawbacks and how well-suited it is for different jobs. The main results that have been obtained by this research are: the HTA technique is an appropriate selection when the analysis seeks to explore the connections and interdependencies among different components of the task, whereas CTA is appropriate for the analysis that necessitates a technique with an undefined structure comprising of interviews. If the analysis system seeks to identify a cognitive process with a clearly defined structure, the GOMs technique can be a superb option. Lastly, when the task analysis aims to comprehend the emotional aspects of task performance, the ETA serves as an effective instrument to employ. In terms of usability, HTA is widely utilized in the fields of task assistance design and error prediction. CTA proves to be beneficial for tasks that demand sophisticated cognitive functions, GOMS is typically employed in the creation of training tools, the design of assist frameworks, and the documentation for clients, and ETA examines how users' psychological or emotional states influence their responses to tasks as they complete them. It is advised that readers go over this comparison paper in order to obtain a better knowledge of how to select the precise strategy that can aid in finishing an assignment.

Evaluating the World Health Organization's SkinNTDs App as a Training Tool for Skin Neglected Tropical Diseases in Ghana and Kenya: Cross-Sectional Study.

Neglected tropical diseases (NTDs) affect over 1.5 billion people worldwide, primarily impoverished populations in low- and middle-income countries. Skin NTDs, a significant subgroup, manifest primarily as skin lesions and require extensive diagnosis and treatment resources, including trained personnel and financial backing. The World Health Organization has introduced the SkinNTDs app, a mobile health tool designed to train and be used as a decision support tool for frontline health care workers. As most digital health guidelines prioritize the thorough evaluation of mobile health interventions, it is essential to conduct a rigorous and validated assessment of this app. This study aims to assess the usability and user experience of World Health Organization SkinNTDs app (version 3) as a capacity-building tool and decision-support tool for frontline health care workers. A cross-sectional study was conducted in Ghana and Kenya. Frontline health care workers dealing with skin NTDs were recruited through snowball sampling. They used the SkinNTDs app for at least 5 days before completing a web-based survey containing demographic variables and the user version of the Mobile Application Rating Scale (uMARS), a validated scale for assessing health apps. A smaller group of participants took part in semistructured interviews and one focus group. Quantitative data were analyzed using SPSS with a 95% CI and P≤.05 for statistical significance and qualitative data using ATLAS.ti to identify attributes, cluster themes, and code various dimensions that were explored. Overall, 60 participants participated in the quantitative phase and 17 in the qualitative phase. The SkinNTDs app scored highly on the uMARS questionnaire, with an app quality mean score of 4.02 (SD 0.47) of 5, a subjective quality score of 3.82 (SD 0.61) of 5, and a perceived impact of 4.47 (SD 0.56) of 5. There was no significant association between the app quality mean score and any of the categorical variables examined, according to Pearson correlation analysis; app quality mean score vs age (P=.37), sex (P=.70), type of health worker (P=.35), country (P=.94), work context (P=.17), frequency of dealing with skin NTDs (P=.09), and dermatology experience (P=.63). Qualitative results echoed the quantitative outcomes, highlighting the ease of use, the offline functionality, and the potential utility for frontline health care workers in remote and resource-constrained settings. Areas for improvement were identified, such as enhancing the signs and symptoms section. The SkinNTDs app demonstrates notable usability and user-friendliness. The results indicate that the app could play a crucial role in improving capacity building of frontline health care workers dealing with skin NTDs. It could be improved in the future by including new features such as epidemiological context and direct contact with experts. The possibility of using the app as a diagnostic tool should be considered. RR2-10.2196/39393.

Accepting video conferencing technology as an in-service training tool for health professionals

AbstractThis study investigates healthcare professionals’ acceptance of video conferences for in-service training in terms of performance expectancy and social influence. Furthermore, it attempts to determine which properties of video conferences influenced and predicted the adoption of video conferencing technology. We employed the cross-sectional survey research design, one of the descriptive research designs. The participants consisted of 181 physicians from a medical specialty society. To collect data, we used the Unified Theory of Acceptance and Use of Technology-2 (UTAUT-2) scale. Findings revealed that being able to ask questions during the video conferences, not paying for participation, timing problems, and lack of social interaction predicted the acceptance of video conferences for in-service training regarding performance expectancy and social influence among physicians. This article offers practical recommendations for professionals to adopt and maximize the use of videoconferencing for in-service training. The findings of this study will shed light on future practices and studies regarding the use of video conferencing systems for in-service training by revealing the preferences of physicians and the factors affecting their acceptance behavior.

Training Methods Used by Dog Guardians in the United States: Prevalence, Sources of Information, and Reasons for Use

While there has been recent attention in the scientific community on the ethical and welfare implications of different dog training methods, less research has investigated what methods and training tools United States dog guardians use, where they obtain information about dog training, and the reasons they give for their choices of method. We conducted two surveys with nearly 800 Arizona State University undergraduate students to gain a more realistic look into how dog guardians in the United States train their dogs and where they are receiving their training information. Only 5% of respondents reported utilizing a trainer when they had concerns regarding their dog’s behavior; 60% would ask a friend or family member or seek advice online. Few reported taking their dog to any training classes; 70% reported either training the dog themselves or not implementing any formal training. When asked general questions, most respondents reported using rewards-based methods but, when asked about specific problem behaviors, 57% of respondents noted that they would use auditory or physical corrections. Respondents who trained with rewards-based methods reported that these methods of training were more effective significantly more frequently than those who trained with mixed methods reported that those methods were most effective (Fisher’s Exact Test, p < 0.01).

Evaluation of a 3D Printed Silicone Oral Cavity Cancer Model for Surgical Simulations

Adequate surgical margins are essential in oral cancer treatment, this is, however, difficult to appreciate during training. With advances in training aids, we propose a silicone-based surgical simulator to improve training proficiency for the ablation of oral cavity cancers. A silicone-based tongue cancer model constructed via a 3D mold was compared to a porcine tongue model used as a training model. Participants of varying surgical experience were then asked to resect the tumors with clear margins, and thereafter asked to fill out a questionnaire to evaluate the face and content validity of the models as a training tool. Eleven participants from the Otolaryngology-Head and Neck Surgery unit were included in this pilot study. In comparison to the porcine model, the silicone model attained a higher face (4 vs. 3.6) and content validity (4.4 vs. 4.1). Tumor consistency was far superior in the silicone model compared to the porcine model (4.1 vs. 2.8, p = 0.0042). Fellows and staff demonstrated a better margin clearance compared to residents (median 3.5 mm vs. 1.0 mm), and unlike the resident group, there was no incidence of positive margins. The surgical simulation was overall useful for trainees to appreciate the nature of margin clearance in oral cavity cancer ablation.

Improving Agility and Reactive Agility in Basketball Players U14 and U16 by Implementing Fitlight Technology in the Sports Training Process

The main aim of this research was to evaluate the impact of the implementation of Fitlight technology in the process of sports training and motor assessment on the improvement in agility and reactive agility of junior basketball players. The age groups studied were under-14 (U14) and under-16 (U16). This study included 70 male basketball athletes, structured in two experimental groups: U14 (18 subjects) and U16 (17 subjects); two control groups: U14 (18 subjects) and U16 (17 subjects). Arithmetic averages of the anthropometric characteristics of the subject groups: experimental group U14: height 172.89 cm, weight 58.22 kg, BMI 19.56; control group U14: height 165.44 cm, weight 50.17 kg, BMI 18.53; experimental group U16: height 179.94 cm, weight 70.82 kg, BMI 20.35; control group U16: height 183.88 cm, weight 73.41 kg, BMI 20.83. An 18-week experimental program that integrates Fitlight technology in order to develop coordination and agility skills and corrective agility was implemented in the experimental groups. This study included six tests: T agility test, T agility test with ball, reactive T agility test, reactive T agility test with ball, Illinois agility test, and Illinois agility test with ball. The results of this study showed statistically significant progress between the initial and final testing for the experimental group, p < 0.05. The Cohen’s values of the experimental groups were above 0.8, which denotes a large effect size; for the control group, these sizes were small and medium. The comparative analysis of the experimental and control groups, U14 and U16, highlights significant statistical differences in favor of the experimental groups, for all the agility tests of this study. This study highlights the effectiveness of incorporating advanced training tools like Fitlight in sports training, particularly for young basketball players. This approach surpasses traditional methods in enhancing agility, suggesting a paradigm shift towards technology-integrated training in sports.

Effect of three months high-intensity anaerobic treadmill-based exercise on intuitive decision-making capability

Background. Quick decision making capability is critical for handling critical situation. Intuitive decision making is most desirable for situations requiring quick and heedful decisions. Decision making, just like other cognitive skills can be modified through several factors like physical activity. In this study we aim to decipher the effects of high-intensity treadmill-based exercise on intuitive ability. Methods. A prospective cohort design with convenience sampling with a sample of 80 participants from various gym centres. Following ethical approval and informed consent, participants were divided in to either no exercise (NE) (n = 38) condition or treadmill-based exercise (TBE) group (n = 42). Data on socio-demographic characters, self-reported mental health history and IDM scores were obtained. Data were obtained at baseline and after 34 sessions of treadmill-based exercise for TBE and 12 weeks of normal physical activity for NE group. Mixed-factor ANOVA, paired t-test and regression analysis was used utilizing SPSS version 21. Results. A significant improvement in IDM scores was observed in TBE group after 34 exercise sessions as compared to NE group (p < .01). A significant interaction of time points and group was also revealed through mixed-factor ANOVA (p < .01). Socio-demographic characters and mental health history had no significant impact on IDM scores. Chi-square analysis of the IDM sub-categories showed a significant increase in intuitive decision making individuals in the TBE group post intervention (p < .01). Conclusion. Exercise training can be used as a potential training tool for improving decision making outcomes in critical settings.

The feedback dilemma in medical education: insights from medical residents’ perspectives

BackgroundFeedback is a critical component of the learning process in a clinical setting. This study aims to explore medical residents’ perspectives on feedback delivery and identify potential barriers to feedback-seeking in clinical training.MethodsThis cross-sectional study involved 180 medical residents across seventeen specialties. We employed the validated Residency Education Feedback Level Evaluation in Clinical Training (REFLECT) tool to assess residents’ perspectives on their attitude toward feedback, quality of feedback, perceived importance, and reaction to feedback. Additionally, we explored barriers to feedback-seeking behavior among medical residents.ResultsThe majority of medical residents held positive attitudes toward feedback. They agreed that feedback improves their clinical performance (77.7%), professional behavior (67.2%), and academic motivation (56.7%), while also influencing them to become a better specialist in their future career (72.8%). However, the study revealed critical deficiencies in the feedback process. Only 25.6% of residents reported receiving regular feedback and less than half reported that feedback was consistently delivered at suitable times and locations, was sufficiently clear or included actionable plans for improvement. A minority (32.2%) agreed that faculty had sufficient skills to deliver feedback effectively. Moreover, peer-to-peer feedback appeared to be a primary source of feedback among residents. Negative feedback, though necessary, often triggered feelings of stress, embarrassment, or humiliation. Notably, there were no significant differences in feedback perceptions among different specialties. The absence of a feedback-seeking culture emerged as a central barrier to feedback-seeking behavior in the clinical setting.ConclusionsEstablishing shared expectations and promoting a culture of feedback-seeking could bridge the gap between residents’ perceptions and faculty feedback delivery. Furthermore, recognizing the role of senior and peer residents as valuable feedback sources can contribute to more effective feedback processes in clinical training, ultimately benefiting resident development and patient care.

Improving the social communication skills of preschoolers with autism spectrum disorder: robot-based intervention on Picture Exchange Communication System use

Objectives Children diagnosed with autism spectrum disorder (ASD) often exhibit challenges in social communication. Picture Exchange Communication System (PECS) is effective in enhancing the social skills of children with ASD, and interventions using social robots are potentially beneficial training tools. However, it is uncertain whether robots can facilitate more effective training for children with ASD compared to human therapists. Methods In the present study, we compared the effectiveness of robot-based and human-based interventions on enhancing the social communication behaviors in young children diagnosed with ASD. The feasibility and efficacy of integrating the PECS in robotic systems were evaluated using a single-case design. Eight children with ASD were randomly assigned to either a robot-based group (N = 4) or a human-based group (N = 4). Participants in the two groups underwent phases I–III of the PECS protocol facilitated by either a human therapist or a robot therapist. Changes in social communication behaviors were assessed in each child after intervention using a single-case design. Results Half of the participants in the robot-based intervention group showed significant improvement in both verbal and nonverbal communication behaviors after a two-month PECS intervention. A higher proportion of children in the robot-based intervention group showed significantly enhanced social communication skills encompassing both verbal and nonverbal behaviors than in the human-based intervention group. Conclusions This study demonstrates the effectiveness of robot-based PECS intervention in enhancing verbal and nonverbal communication behaviors in young children with ASD. These findings present novel intervention tools for early intervention educators engaged in supporting children with ASD.
