Abstract Background Simulation-Based Learning (SBL) serves as a valuable pedagogical approach in nursing education, encompassing varying levels of fidelity. While previous reviews have highlighted the potential effectiveness of SBL in enhancing nursing students’ competencies, a gap persists in the evidence-base addressing the long-term retention of these competencies. This systematic review aimed to evaluate the impact of SBL on nursing students’ knowledge and skill acquisition and retention. Method A comprehensive search of electronic databases, including CINAHL, PubMed, Embase, Scopus, and Eric, was conducted from 2017 to 2023 to identify relevant studies. The Joanna Briggs critical appraisal tools were used to assess the methodological quality of the included studies. A total of 33 studies (15 RCTs and 18 quasi-experimental) met the inclusion criteria and were included in the review. A descriptive narrative synthesis method was used to extract relevant data. Results The cumulative sample size of participants across the included studies was 3,670. Most of the studies focused on the impact of SBL on life-saving skills like cardiopulmonary resuscitation (CPR) or other life-support skills. The remaining studies examined the impact of SBL on critical care skills or clinical decision-making skills. The analysis highlighted consistent and significant improvements in knowledge and skills. However, the evidence base had several limitations, including the heterogeneity of study designs, risk of bias, and lack of long-term follow-up. Conclusion This systematic review supports the use of SBL as a potent teaching strategy within nursing education and highlights the importance of the ongoing evaluation and refinement of this approach. While current evidence indicates enhancing knowledge and skill acquisition, limited studies evaluated the retention beyond five months, constraining generalisable claims regarding durability. Further research is essential to build on the current evidence and address gaps in knowledge related to the retention, optimal design, implementation, and evaluation of SBL interventions in nursing education.

Background and Aims: Traditional apprenticeship‐based surgical training presents with challenges, especially in acute scenarios. Simulation provides the current standard of facilitating surgical training in a low‐risk environment but is restricted by limited accessibility and high costs. Virtual reality (VR) offers immersive three‐dimensional computer‐generated training scenarios and can connect users from various locations. We aimed to compare the performance of junior doctors to manage an acute surgical scenario using VR and mannequin‐based simulation. We hypothesised that VR would be as effective as mannequin‐based simulation in performance outcomes. Methods: This multicentre, randomised controlled pilot study was conducted with eighteen junior doctor volunteers (Foundation and Core Trainee Year 1). Ten were randomly allocated to VR and eight to mannequin‐based simulation. Participants completed questionnaires and a 15‐min pneumothorax scenario. Quantitative metrics included overall score, time‐to‐critical decisions, and academic buoyancy scores (ABS). Qualitative metrics included participants' likes and dislikes of their allocated simulation modality. Results: VR participants scored significantly higher than mannequin‐based simulation participants in overall scores (74.30% (SD ± 5.08%) vs. 59.75% (SD ± 10.14) (p = 0.04)), and technical skills aspects (77.20% (SD ± 8.01%) vs. 65.00% (SD ± 8.21%) (p = 0.01)). Mannequin‐based simulation participants initiated critical decisions faster and demonstrated a trend towards a faster mean time‐to‐completion (p = 0.06). ABS scores increased for both study groups, though was only significant for VR participants (p ≤ 0.01). VR participants liked how VR fostered independent learning but disliked the formulaic content and impaired communication‐learning compared to mannequin‐based simulation. Conclusion: Both VR and mannequin‐based simulation training are effective in training junior doctors in acute surgical scenarios but present different educational benefits. Future research should recruit a larger sample size for a full comparative randomised controlled trial. [ABSTRACT FROM AUTHOR]

Introduction: The use of simulation is extremely useful in pregraduate students. However, there is a very small number of simulators adapted to paediatric dentistry. A paediatric simulator was created to use in simulated scenarios for paediatric dentistry using an actress in the role of mother. The objectives of the present study were three. First, to analyse the perception of clinical competencies acquired by the students. Second, to examine the realism perceived by the students. Finally, to analyse the influence on the perception of clinical competencies after the integration of a handmade simulator in the Paediatric Dentistry III course. Materials and Methods: Eight clinical scenarios were carried out with a modified Erler Zimmer simulator for children, a professional actress in the role of the mother and two students (in the roles of dentist and assistant) on a paediatric dentistry case of pulpal pathology. The educational intervention was evaluated on 114 students by means of questionnaires with Likert‐type answers applied pre‐ and post‐simulation. Results: The perception of clinical competence in the students increased an average of 0.956 points in relation with the initial clinical evaluation, finding a strong correlation between the perception of subsequent competence and all the perceived realism, with significant statistical differences in all cases. The realism of the simulated participant (professional actress) was the best rated by the students, although not significantly. The realism of the mannequin was positively and strongly correlated with the perceived realism of the cabinet. Conclusion: Simulation using a handmade mannequin with a professional actress in a simulated dental office increased the perception of clinical competence in 4th year dental students and raised the level of overall realism perceived by the student.

Abstract Introduction Accidental extubation during prone position can be a life-threatening emergency requiring rapid establishment of the airway. However, there is limited evidence of the best airway rescue method for this potentially catastrophic emergency. The aim of this study was to determine the most effective method to recover the airway in case of accidental extubation during prone positioning by comparing three techniques (supraglottic airway, video laryngoscopy, and fiber-optic bronchoscopy) in a simulated environment. Methods Eleven anesthesiologists and 12 anesthesia fellows performed the simulated airway management using 3 different techniques on a mannequin positioned prone in head pins. Time required for definitive airway management and the success rates were measured. Results The success rates of airway rescue were 100% with the supraglottic airway device (SAD), 69.6% with the video laryngoscope (CMAC), and 91.3% with the FOB. The mean (SD) time to insertion was 18.1 (4.8) s for the supraglottic airway, 78.3 (32.0) s for the CMAC, and 57.3 (24.6) s for the FOB. There were significant differences in the time required for definitive airway management between the SAD and FOB (t = 5.79, p

Modeling has become popular in many societies today as one of the advertising arms of the fashion industry. Women are one of the important elements in this activity. Women's modeling has become one of the most challenging issues with the expansion of cyberspace in Iran. This research, by taking a descriptive-analytical method with a practical purpose and by collecting information from library and Internet sources, seeks to explain the gaps in the field of women's modeling in the Iranian legal system and to provide related proposals. This is done by examining the licenses, restrictions, and prohibitions of women's modeling in Iranian law. Based on the findings of this study, in the Iranian legal system, specific rules and regulations for Women's modeling are not specifically provided. Of course, there are rules and regulations in the fields of fashion and clothing, advertising, and cyberspace, which may include some types of modeling. From the present study, it can be concluded that the Iranian legal system does not have a specific approach to modeling and the legal gap in this regard is tangible. The recent reality has caused Women's modeling, which has emerged as a social phenomenon, to lead to undesirable results if not guided and monitored properly.

Abstract Background The traditional teaching methods of dental education are gradually being replaced with futuristic education methods based on the usage of educational tools such as mannequin-based simulation models and virtual reality. However, the effectiveness of mannequin-based simulation models as a learning method in the field of oral surgery remains unclear. This study aims to investigate the efficacy of training on a tooth extraction model (TEM) in view of undergraduate dental students’ experience and perception of their education. Methods A quasi-experimental trial was implemented with two consecutive year classes, totaling 136 students at the Dentistry Faculty of Altinbas University, Turkiye. Two cohorts were created from dental students in the classes of 2023 and 2022 graduates. Cohort 1 (n = 71) received 14 h of theoretical education followed by 10 h of preclinical education on TEM. Cohort 2 (n = 65) received only 14 h of theoretical education. An anonymous questionnaire was prepared with four main sections including the preferences of learning style, participants’ perceptions of the preclinical training methods, the students’ competency and free text comments. Students’ opinions were quantified with both 7-point Likert scales and thematic analysis. Anxiety levels were measured with the interval scale of anxiety response (ISAR). Descriptive statistics, inferential statistical and thematic analyses were conducted according to survey responses. Student characteristics were summarized and compared for two cohorts using a t-test. For all statistical analyses, the significance level was set atP ≤ 0.05. Result Cohort 1 was more comfortable with sequential motions performed with the forceps (P = 0.033) and felt more ready for their first clinical tooth extraction experience (P = 0.028). Cohort 2 showed a significantly higher preference for textbooks among supplementary materials (P = 0.04); however, they tended to exhibit lower self-confidence and higher anxiety levels, though without any statistical significance (P > 0.05). Conclusion It is clear that the students who have yet to start seeing patients benefit from increased practice with training models, which adequately reflect and represent real-life situations encountered in everyday practice.

This document summarizes a comparative study that examined the effectiveness of video-based teaching versus mannequin-based teaching for teaching parenteral drug administration to medical undergraduates. The study found that both methods improved students' knowledge, but mannequin-based teaching was more effective in improving students' perception and skill. However, the study also acknowledged the limitations of simulation-based education and suggested using a combination of teaching methods for effective clinical skills training.

Introduction: CPR is an important lifesaving skill that can improve outcomes of patients in cardiac arrest. Mass training of hands-only CPR is one of the ways to spread information and teach this skill. Need for expensive CPR mannequins are a limiting factor in conducting such mass training programmes. This study assessed the effectiveness of a low-cost CPR pillow model in training hands-only CPR. Methodology: Two hundred and six undergraduate students underwent a two-hour CPR training session. They were randomly divided into two groups – mannequin group and CPR pillow group and practiced hands-only CPR on a standard mannequin and a low-cost CPR pillow model, respectively. Knowledge, attitude, and skill acquisition were objectively assessed and compared between the two groups. Results: There was no statistical difference in hand positioning, chest compression rate and fraction, depth and overall CPR score between the two groups trained via mannequin and CPR Pillow (P > 0.05). The CPR pillow group had better percentage of chest recoil as compared to the mannequin group (86% vs 73%; P

• Learning skills for operative vaginal delivery. • Residency programme on labour and delivery simulators. • Retention of acquired skills. • Obstetric emergency and simulator training. To assess the effect of two modalities of simulation training on acquisition/retention of skills for performing operative vaginal delivery. Randomized, controlled, single-centre study. A tertiary referral hospital in Italy. Twenty residents from a single university programme and two young specialists. Group 1 had an individual training session with a single senior specialist using a fixed simulator model. After the session, trainees watched a pre-recorded 1-h lecture on vacuum-assisted operative vaginal delivery. Group 1 repeated the simulator session using the same test after 8–12 weeks and 12 months. Group 2 watched the pre-recorded lecture then undertook the same sessions as Group 1. Video recordings of all test performances were evaluated by five specialists in a blinded manner. Each procedure was evaluated using a Global Rating Scale (GRS), scored with 0–5 points for each item on an Objective Structured Assessment of Technical Skills (OSATS) dataset with seven items (total 35 points). OSATS were evaluated over time, compared for the whole population, and weighted for route and year of residency. The primary outcome was comparison of the effectiveness of training between the two groups based on year of residency by assessing videos of the baseline test and GRS for OSATS scores. The secondary outcome was overall retention of skills at 8–12 weeks and 12 months. Twenty-two participants were recruited and randomized to either Group 1 (n = 11) or Group 2 (n = 11). Five participants did not complete follow-up. The primary outcome of GRS for OSATS scores at time 0 differed significantly between groups for total GRS score, and 'Call for help' and 'Explanation to woman and relatives' item scores (p = 0.002 and p = 0.007, respectively). In a multiple linear regression analysis, OSATS scores were not independently influenced by year of residency. At 8–12-week follow-up, the 'Call for help' item score showed a significant improvement in Group 1 (p = 0.018), although this was not confirmed when year of residency was included as an independent variable. At 12-month follow-up, none of the item scores demonstrated a significant change (p = 0.033). Year of residency did not influence the difference between groups. One-way analysis of variance found significant differences between the groups for 'Localization of the flexion point' (p = 0.005), 'Traction of vacuum cup' (p = 0.039) and 'Use of second hand of the operator' (p = 0.009) item scores and total GRS score (p = 0.007). The values weighted by year of residency did not demonstrate any significant difference. The secondary outcomes evaluated all the candidates of both groups for retention of technical skills over time. A significant effect of time was found for total GRS score (p < 0.001) and OSATS item scores. Independent of the sequence of theoretical teaching and simulation training, trainees demonstrated high retention – and, actually, improvement – of technical skills for operative vaginal delivery at 12-month follow-up.

In order to better apply digital technology to the clothing industry, we broke through the traditional method of obtaining clothing samples, and combined reverse engineering method with three-dimensional clothing design to design the structure and function of young women's night running clothes. Firstly, the human body data of 103 female college students were collected by using 3D body scanner and analyzed by SPSS software. The human body model was constructed by using 3D virtual design platform, and the outer contour curve of clothing was directly drawn on the human body model to construct the basic clothing surface. Then, according to the style drawing, the dividing line was drawn, the 3D clothing surface was flattened to obtain the 2D sample, and the 3D virtual fitting software was used for virtual fitting. The virtual pressure test was performed on 26 pressure points in 6 postures of running, and the pressure of the two types of clothing was compared. Finally, the night running clothes design was combined with Lilypad Arduino development board to determine the final style design for sample garment production and subjective evaluation by comparing the virtual pressure values of the night running clothes. The evaluation results show that the proposed method is effective for the automatic generation of tight-fitting garment design and pattern generation.

Background: Training is required to achieve proficiency in airway management. Simulators are of utmost importance not only for the purpose of training novices, but also for evaluating newer airway devices and techniques. Growing evidence supports inadequate anatomic airway reproduction in adult and pediatric manikins. Methods: We conducted an observational study comparing 17 radiological anatomic airway measurements obtained via the computed tomography of three commercially available manikins with the same measurements obtained from a population of newborns/infant (range: 0–3 months) undergoing magnetic resonance imaging for diagnostic purposes. According to the reference (mean and standard deviation (SD) of the pediatric population), each manikin measurement was defined as adequate, partially adequate or inadequate (difference between means: ≤±1, 1.0–1.96 or >1.96 SD, respectively). The primary outcome was the number of measurements with an adequate reproduction of airways. Results: We included 27 pediatric patients (21 ± 19 days, 48% males, 46.6 ± 3.5 cm, 2.7 ± 0.5 Kg and 12.6 ± 2.9 kg/m2). All manikins had n = 11/17 measurements with inadequate airway anatomic reproduction. The three measurements with more adequate reproduction were the height of the soft palate, retropalatal airspace volume and tongue volume (adequate in two manikins, and partially adequate in the remaining one). Conclusions: In three manikins commonly used for training in pediatric airways, static dimensions do not seem anatomically correct in relation to those of pediatric patients. Such inaccuracies may introduce biases in airway device development as well as in training. [ABSTRACT FROM AUTHOR]

ObjectiveTo investigate the relationship between the perpetrator’s sex, victim’s position and slashing location as well as anthropometric parameters on distance and space required for slashing, to provide the theoretical basis for the judgment of whether the crime scene was consistent with the criminal activity space.MethodsThe kinematics data of 12 male and 12 female subjects slashing the neck of standing and supine mannequins as well as the chest of the standing mannequins with a kitchen knife were obtained by using a 3D motion capture system. The relationship between the perpetrator’s sex-victim’s position, the perpetrator’s sex-slashing location, and anthropometric parameters and the distance and space required for the slashing were analyzed by two-factor repeated measures ANOVA and Pearson correlation analysis respectively.ResultsCompared with slashing the neck of supine mannequins, the distance （L） and normalized L （l） of slashing the neck of standing mannequins were greater, while vertical distance （LVR） and normalized LVR （lVR） of the knife side were smaller. Compared with slashing the neck of standing mannequins, the L and l slashing the chest of standing mannequins were greater, while LVR and lVR were smaller. Horizontal distance （LHR） and normalized LHR （lHR） of the knife side in males were greater than that in females. Height and arm length were positively correlated with L, LHR, and LVR when striking the standing mannequins.ConclusionWhen slashing the neck of supine or standing victims, the slashing distance is shorter and the slashing height is greater. Furthermore, the distance and space required for slashing are correlate with anthropometric parameters.

Featured Application: diagnosis of hypothermia, assistance with care for low-birth-weight neonates. The effectiveness of skin-to-skin care (SSC) notably depends on the delivery room air temperature (Ta), the thermal insulation provided by the fabrics or clothes covering the mother and the neonate (Icl), and the neonate's metabolism (M). The objective of the present study was to model the influence of these variables on the effectiveness of SSC for premature newborns. To this end, we used an appropriate thermal mannequin and applied a mathematical model of body heat exchanges. We performed experiments at Ta values (20.9 °C and 25.9 °C) and two Icl values (sheet only and sheet + blanket). At a Ta of 25.9 °C, normothermia was estimated after one hour of SSC with the sheet (Icl = 0.15 m2 °C/W; 36.52 °C) and the sheet + blanket (Icl = 0.21 m2 °C/W; 37.09 °C) but only with the highest value of M (2.70 W/kg). With a Ta of 20.9 °C, moderate hypothermia (requiring monitoring of the neonate's thermal status) was estimated—except for M = 2.70 W/kg and Icl = 0.21 m2 °C/W. During early SSC, homeothermy can be maintained when Ta is 25 °C (the temperature recommended by the World Health Organization) but only when the neonate's tissue insulation is high (Icl ≥ 0.15 m2 °C/W) and when the level of metabolic heat production is high.

Implementation of Machine Learning (ML) to improve product and production development processes poses a significant opportunity for manufacturing industries. ML has the capability to calibrate models with considerable adaptability and high accuracy. This capability is specifically promising for applications where classical production automation is too expensive, e.g., for mass customization cases where the production environment is uncertain and unstructured. To cope with the diversity in production systems and working environments, Reinforcement Learning (RL) in combination with lightweight game engines can be used from initial stages of a product and production development process. However, there are multiple challenges such as collecting observations in a virtual environment which can interact similar to a physical environment. This project focuses on setting up RL methodologies to perform path-finding and collision detection in varying environments. One case study is human assembly evaluation method in the automobile industry which is currently manual intensive to investigate digitally. For this case, a mannequin is trained to perform pick and place operations in varying environments and thus automating assembly validation process in early design phases. The next application is path-finding of mobile robots including an articulated arm to perform pick and place operations. This application is expensive to setup with classical methods and thus RL enables an automated approach for this task as well. [ABSTRACT FROM AUTHOR]

This paper distinguishes the design and analysis of 3 × 2 circular microstrip patch probe array for specific absorption rate (SAR) measurement at quad-band. This novel approach consists of FR4 substrate radial dimension of 88 mm and it has six circular array elements with a radius of 17 mm; out of these six elements, three array elements are having rectangular slots with dimensions of 1.8 × 1.5 × 1.5 mm3. The array elements are coupled with six probes which have a dimension of 100 mm with a 2.5 mm tip radius; these six probes are embedded into a tissue-equivalent liquid-filled human head mannequin. In this mannequin, instantaneous SAR at any six positions has been investigated. The proposed design resonates at 1.8, 2.1, 2.4, and 2.5 GHz with a return loss of −11.53, −15.90, −15.73, and −25.49 dB. The circular microstrip probe array is fed by a 50 Ohm coaxial feed. In addition, the 3D human head model analysis is also presented. The precisely estimated SAR values are 0.135, 0.108, 0.167, and 0.244 W/kg at 1 g of tissue. For the traceable measurements, each source of uncertainty budget has been estimated. [ABSTRACT FROM AUTHOR]

Irena Kossowska’s “A Quest for a ‘New Man’: Bruno Schulz and Giorgio de Chirico” published in Realisms of the Avant-Garde (2020) analyses the work of the Polish Jewish writer Bruno Schulz (1892 – 1942) from the perspective of the category of the “new man”. In his writing, Schulz employed cultural syncretism and eclecticism that aimed at innovation. He paraphrased and intertwined chosen models and formed new semantic entities and the previously non-existent innovative combinations. Trying to trace the original myth diluted in various layers of culture, he combined heterogeneous elements derived from mutually antagonistic sources into a homogenous vision. In the construction of his own private mythology from fragments and “shreds of sculptures and statues of gods”, Schulz used various elements of the cultural heritage. This contribution situates Kossowska’s chapter into the context of Schulz’s understanding of his own work as mythologizing the reality and creating private mythology from developing key images of the unconscious originating in childhood. Metamorphoses of entities in Schulz’s literary universe spring from the fermentation of the matter. With regards to the motif of mannequins and the Demiurge, the contribution provides a supplementary context that is relevant for the matter under discussion – Judaism and the creation of golems (R. Lachmann, V. Nelson, M. Benešová) and parodies of Gnosticism.

The article concerns the graduation puppet performance Wrocław: Escape Room, directed by Arkadiusz Buszko from the National Academy of Theatre Arts in Kraków at the Puppetry Department in Wrocław. The narrative of the performance is set in post-apocalyptic Wrocław, and the heroes are historic figures connected with this city at various stages of their lives. An analysis of the performance, with particular emphasis on the role and form of puppets, animated objects and costumes, made it possible to assess how the staging concepts of the creators contributed to the horror effect and how they influenced the presentation of the characters. The authors of the Wrocław diploma piece utilized the puppets’ potential for formal transformations in creating characteristic, fascinating, but also quite frightening puppets and costumes made of fragments of mannequins. Therefore, the analysis of the elements of the performance was supplemented with considerations on the mannequins and their role in the theatre. The second category that is significant for the interpretation of the performance is the notion of a monster. Research on the perception of monsters in culture proved to be helpful, as it allowed for reading the characters of the performance through the lens of monstrosity. [ABSTRACT FROM AUTHOR]

Background: This randomised crossover mannequin study aimed to compare the insertion time for the newly developed SingularityTM Air and the Ambu® AuraGainTM. The SingularityTM Air includes a bendable tube in order to allow optimal passform. Methods: Fifty anaesthetists with a minimum of 100 supraglottic airway device insertions were recruited and randomly assigned to start either with the SingularityTM Air or with the Ambu® AuraGainTM. Participants watched a tutorial video the day before the assessment and received a standardized introduction immediately before the assessment. The primary outcome was the time for successful insertion. Secondary parameters were the overall insertion success rate, the numbers of insertion attempts (maximum three), the glottic view through a flexible bronchoscope, and the success rate for gastric tube insertion. Results: Fifty participants were eventually recruited and randomly assigned to insert both devices according to the randomization. The insertion time was 24 s for SingularityTM Air as compared to 20 s for Ambu® AuraGainTM (p < 0.001). Overall insertion rate was 92% for the SingularityTM Air as compared to 100% for the Ambu® AuraGainTM (p could not be derived as one variable is a constant). The primary insertion success rate was better for the Ambu® AuraGainTM than for the SingularityTM Air (94% versus 68%; p: 0.002, respectively).

Infant cardiopulmonary resuscitation (iCPR) is often poorly performed, predominantly because of ineffective learning, poor retention and decay of skills over time. The aim of this study was to investigate whether an individualized, competence-based approach to simulated iCPR retraining could result in high skill retention of infant chest compressions (iCC) at follow-up. An observational study with 118 healthcare students was conducted over 12 months from November 2019. Participants completed pediatric resuscitation training and a 2-min assessment on an infant mannequin. Participants returned for monthly assessment until iCC competence was achieved. Competence was determined by passing assessments in two consecutive months. After achieving competence, participants returned just at follow-up. For each 'FAIL' during assessment, up to six minutes of practice using real-time feedback was completed and the participant returned the following month. This continued until two consecutive monthly 'PASSES' were achieved, following which, the participant was deemed competent and returned just at follow-up. Primary outcome was retention of competence at follow-up. Descriptive statistics were used to analyze demographic data. Independent t-test or Mann–Whitney U test were used to analyze the baseline characteristics of those who dropped out compared to those remaining in the study. Differences between groups retaining competence at follow-up were determined using the Fisher exact test. On completion of training, 32 of 118 participants passed the assessment. Of those achieving iCC competence at month 1, 96% retained competence at 9–10 months; of those achieving competence at month 2, 86% demonstrated competence at 8–9 months; of those participants achieving competence at month 3, 67% retained competence at 7–8 months; for those achieving competence at month 4, 80% demonstrated retention at 6–7 months. Conclusion: Becoming iCC competent after initial training results in high levels of skill retention at follow-up, regardless of how long it takes to achieve competence. What is Known: • Infant cardiopulmonary resuscitation (iCPR) is often poorly performed and skills decay within months after training. • Regular iCPR skills updates are important, but the optimal retraining interval considering individual training needs has yet to be established. What is New: • Infant chest compression (iCC) competence can be achieved within one to four months after training and once achieved, it can be retained for many months. • With skill reinforcement of up to 28 minutes after initial training, 90% of individuals were able to achieve competence in iCC and 86% retained this competence at follow-up.

Background: Epiglottic masses are often asymptomatic, making them difficult to detect during preoperative examinations. Consequently, anesthesiologists may face ventilation difficulties with no apparent cause. Epiglottic masses can sometimes obstruct laryngoscope insertion into the epiglottic vallecula, complicating general anesthesia induction. In such cases, supraglottic airway insertion may be a viable alternative; however, the limited case reports on its use for epiglottic masses make its applicability unclear. Therefore, we test the hypothesis that a larger laryngeal artificial mass could obstruct the view of the larynx, even when supraglottic airways are used in a mannequin study., Methods: We utilized an airway management simulator (Air Sim Multi®: Nihon 3B Scientific, Japan) to place various sizes of artificial masses (tumors) above the epiglottis. The groups included a control group with no mass, small size mass group, middle size mass group, and large size mass group. The supraglottic airway (i-gel®: Intersurgical, UK) was then inserted 10 times. We categorized the view of the vocal cords using a bronchoscope inserted through the tip of the cuff according to the Cormack-Lehane classification. In addition, we performed pressure-controlled ventilation, adjusting the inspiratory pressure from 10 cm H₂O to 25 cm H₂O, while measuring the tidal volumes., Results: The Cormack-Lehane classification grade increased in correlation with the mass size. In each inspiratory pressure, tidal volume decreased in correlation with the mass size. Furthermore, in the large-size mass group, even at an inspiratory pressure of 25 cm H₂O, achieving the tidal volume required for general adult respiratory management was deemed difficult., Conclusion: In a mannequin study, we observed that epiglottic masses significantly increased the Cormack-Lehane classification grade and reduced tidal volume, with these effects correlating with the size of the mass. This finding suggests that the appropriateness of using a supraglottic airway may depend on the size and weight of the epiglottic mass., Competing Interests: Human subjects: All authors have confirmed that this study did not involve human participants or tissue.

This research aims to study the possibility of designing expressive fashion on the mannequin as a wearable art inspired by the architectural heritage of of Saudi Arabia using recycled materials, to find new artistic features characterized by originality and modernity, and highlighting the artistic and aesthetic features of heritage buildings according to each region with an expressive technical nature compatible with the art Fashion design. The research followed the descriptive analytical method in studying the concept of wearable art, its beginnings and its historical and creative development, and in analyzing and describing the styles of traditional buildings in Saudi Arabia:1- Hijaz style (Hijaz house - Hijaz palaces)2- Najdi style (Najdi House - Al-Duryia Buildings)3- The Southern style (Asiri House - Al Asha Al Jawizah)In addition to the applied study that resulted in eight designs of expressive costumes on the mannequin as a wearable art that mimics the architectural heritage of Saudi Arabia with recycled materials and materials (paper - cardboard - fabric scraps - stones - wood - buttons - threads - burlap - wicker).The arbitrators agreed that the designs are actual applications of wearable art, and clearly indicate the traditional buildings borrowed from them. The relationship between wearable art and heritage is also present to reflect the diversity of cultures, geographical locations, nature and human mood in past times.The research recommended organizing local art competitions between universities in the field of wearable fashion and arts, and then elevating them to international partnerships, and taking advantage of historical study to stimulate this type of arts and support it commercially in exhibitions and events and scientifically by including it in the curricula and scientific research.

The department store mannequin is often read as representative of commodity or sexual fetishism and, consequently, of woman objectified. This article posits that in Émile Zola's Au Bonheur des Dames (1883), the mannequin can highlight such objectification to the woman in the text. Through close readings of the text's mannequins this article seeks to analyse the combination of estrangement and excitement which characterizes the experience of living under modernity. It asks whether the headless Zolian mannequin empowers the shopper to recognize and thus reject objectification of the self, or if it is simply a disquieting reminder of one's own powerlessness.

Irena Kossowska's "A Quest for a 'New Man': Bruno Schulz and Giorgio de Chirico" published in Realisms of the Avant-Garde (2020) analyses the work of the Polish Jewish writer Bruno Schulz (1892 -- 1942) from the perspective of the category of the "new man". In his writing, Schulz employed cultural syncretism and eclecticism that aimed at innovation. He paraphrased and intertwined chosen models and formed new semantic entities and combinations. Trying to trace the original myth diluted in various layers of culture, he combined heterogeneous elements derived from mutually antagonistic sources into a homogenous vision. In the construction of his own private mythology from fragments and "shreds of sculptures and statues of gods", Schulz used various elements of the cultural heritage. This contribution situates Kossowska's chapter into the context of Schulz's understanding of his own work as mythologizing the reality and creating private mythology from developing key images of the unconscious originating in childhood. Metamorphoses of entities in Schulz's literary universe spring from the fermentation of the matter. With regards to the motif of mannequins and the Demiurge, the contribution provides a supplementary context that is relevant for the matter under discussion -- Judaism and the creation of golems (R. Lachmann, V. Nelson, M. Benešová) and parodies of Gnosticism. [ABSTRACT FROM AUTHOR]

For 300 years now, obstetrics has drawn on the concept of simulation training to not only teach anatomy and physiology theoretically, but to literally infuse it practically. In an 18th century scientific culture, which was predominantly patriarchal, the French royal midwife Angelique Marguerite Le Boursier du Coudray excelled in this field. Using La Machine, one of the first obstetric phantoms, she taught thousands of midwives and even physicians. The exponential increase in publications on obstetric simulations in recent years continues to underline their current relevance, and Madame du Coudray was once at the forefront with her mannequin, probably the most sophisticated phantom of its time, a symbiosis of practical-robust architecture and anatomical-theoretical accuracy. In retrospect, it is therefore worthwhile to take a closer look at this pioneer and her obstetric phantoms, applied in the first national simulation-based training course, and to evaluate them in the overall picture of the development of anatomically correct replicas for practice-oriented training with detailed, flexible exercise – back to the roots.
