Differences between image presentation and video presentation on the outcome of teaching about the menstrual cycle

ABSTRACT Previous research has shown that students have numerous misconceptions about the menstrual cycle, especially when it comes to determining ovulation days. It has also been shown that using a high-quality pictorial representation is of key importance for dispelling misconceptions. Today’s students are used to quick access to information and to its visualisation, so one way to improve the teaching process is to use short video materials. The aim of this research was to determine the impact of a simple video clip in comparison to a pictorial representation on determining ovulation days. The research was carried out on a sample of 122 students from three different high schools in Zagreb with different programmes. The results of the three conducted surveys were collected just before teaching the lesson, after the teaching, and with a time lag of approximately three months after the lesson. Furthermore, students and teachers were asked to say whether they prefer the picture or the video. The results show that there is a difference in the impact of the type of materials on the result of determining the ovulation days, and that both students and teachers consider that the offered video is better material than the offered picture.

Beraksi (Washing Hand, Care Health, Safe from Infection): Health Education to Increase Knowledge of Personal ahygine and Handwashing

Health issues such as diarrhea or worm infections are related to personal hygiene and environmental cleanliness. One contributing factor is handwashing habits. Handwashing is a crucial component of personal hygiene because the consequences of not washing hands can lead to health problems related to the digestive system (diarrhea, worm infections, hepatitis, typhoid, etc.). The objective of this health education is to assess its influence on the knowledge of personal hygiene and handwashing practices among elementary school children at SD Mekasari Sayang in Sumedang district. The implementation method of health education involves using video and poster presentations, lectures, discussions, demonstrations, and simulations with 25 first-grade students of SDN Mekarsari conducted directly. Data analysis utilizes pre-post test design with Wilcoxon statistical testing to identify the significance of differences before and after the health education intervention. The results of the activity demonstrate differences in knowledge and handwashing practices before and after health education using film, posters, discussion, simulation, and demonstration methods (p-value < 0.05). The conclusion drawn from this health education is an improvement in students' knowledge and practices after the intervention. It is hoped that students' awareness and habits regarding personal hygiene behavior will increase, thereby preventing various health problems (diseases) that may arise. Keywords: Personal Hygiene, health education, handwashing, elementary school students.

EMERGENCY LAPAROSCOPIC TRANSABDOMINAL PREPERITONEAL (TAPP) HERNIOPLASTY FOR GARANGEOT'S HERNIA: A CASE REPORT

Abstract Aims This video presentation aims to demonstrate the successful management of a rare and challenging case of Garangeot's hernia through Emergency Laparoscopic Transabdominal Preperitoneal (TAPP) Hernioplasty. The primary objectives include highlighting the surgical technique, intraoperative findings, and postoperative outcomes in the context of this uncommon hernia presentation. Materials and Methods An 84-year-old female presented to the emergency department with signs of femoral hernia incarceration. Upon exploration, a Garangeot's hernia, characterized by the presence of the appendix within a femoral hernia sac, was identified. In light of the emergency and the patient's deteriorating condition, an Emergency Laparoscopic TAPP Hernioplasty was performed. The procedure involved meticulous dissection of the hernia sac, reduction of the herniated appendix and appendectomy, and subsequent mesh reinforcement of the femoral defect. Results The video illustrates the step-by-step approach to Emergency Laparoscopic TAPP Hernioplasty in the context of Garangeot's hernia. Intraoperative findings, including the condition of the herniated appendix and associated anatomical structures, are presented. Postoperative outcomes, including recovery, complications, and follow-up observations, are discussed to provide a comprehensive understanding of the case. Conclusions Emergency Laparoscopic TAPP Hernioplasty emerges as a viable and effective intervention for Garangeot's hernia, offering advantages such as reduced morbidity, quicker recovery, and minimal surgical trauma. This video contributes valuable insights into the management of this rare hernia presentation, emphasizing the role of minimally invasive techniques in achieving successful outcomes.

Immersive virtual reality as a surgical training tool: A cohort study

BackgroundFew studies have studied the efficacy of using immersive virtual reality (iVR) to teach surgical skills, especially by using real-world iVR recordings rather than simulations. This study aimed to investigate whether viewing 360° iVR instructional recordings produces greater improvements in basic suturing skills of students without prior medical training, beyond traditional methods like reading written manuals or watching 2D instructional videos. Materials and methodsThis was a partially blinded randomized cohort study. 44 pre-university students (aged 17) were randomized equally to either the written instruction manual, 2D instructional video, or iVR recordings. All students first watched a silent 2D demonstration video of the suturing task, before attempting to place three simple interrupted sutures on a piece of meat as a baseline. The time taken for the first attempt was recorded. Students were then given an hour to train using their allocated modality. They attempted the suturing task again, and timings were re-recorded. Four blinded surgically-trained judges independently assessed the quality of the stitches placed both pre and post-intervention. One-way analysis of variance tests (ANOVAs) and independent two-sample t-tests were used to determine the effect of training modality on improvements in suturing scores and time taken to complete suturing from pre to post-training. ResultsFor suturing scores, the iVR group showed significantly larger score improvements than the Written Manual group (p = 0.031, Cohen's D = 0.92), while this iVR advantage was less pronounced when compared with the 2D Video group (p = 0.16, Cohen's D = 0.65). Similarly for time taken to complete suturing, the iVR group had significantly larger time improvements than the Written Manual group (p = 0.045), although this difference was less robust compared to the 2D Instructional Video group (p = 0.34). ConclusionThis study demonstrates that iVR training using real-world 360° instructional recordings produced significantly greater training gains in suturing scores and efficiency compared to reading written text. iVR training also led to larger training gains in both outcome measures than viewing 2D instructional videos, although the differences between them did not reach statistical significance.

The effect of differentiated video presentations of choral performances on aesthetic responses of undergraduate choral and instrumental ensemble musicians

Research examining affective response to media modalities including film, television, gaming, video streaming, and virtual reality is expanding. This study examined aesthetic responses to choral performances presented in two contrasting video formats (stationary and produced). Volunteer undergraduate students ( N = 94) enrolled in ensembles (choral, n = 45; instrumental, n = 49) indicated their aesthetic responses to choral performances of Ēriks Ešenvalds’ “Only in Sleep” by manipulating a Continuous Response Digital Interface (CRDI) dial. Participants viewed video performances of two ensembles, one of which was digitally altered to allow for use of the same audio content for both videos. CRDI data were used to create temporal line graphs depicting participant responses to each video and indicated similar shapes with more intense aesthetic response to the produced video. Statistical analysis of cumulative mean responses to each performance found a main effect of video format (stationary vs. produced) and a video format × presentation order interaction. Initial exposure to each video garnered a more intense response than that of the second video, and the produced video elicited greater magnitude than the stationary perspective video. Findings support further examination of video and other media, studying differentiated impact on aesthetic response to music performances.

DualFluidNet: An attention-based dual-pipeline network for fluid simulation

Fluid motion can be considered as a point cloud transformation when using the SPH method. Compared to traditional numerical analysis methods, using machine learning techniques to learn physics simulations can achieve near-accurate results, while significantly increasing efficiency. In this paper, we propose an innovative approach for 3D fluid simulations utilizing an Attention-based Dual-pipeline Network, which employs a dual-pipeline architecture, seamlessly integrated with an Attention-based Feature Fusion Module. Unlike previous methods, which often make difficult trade-offs between global fluid control and physical law constraints, we find a way to achieve a better balance between these two crucial aspects with a well-designed dual-pipeline approach. Additionally, we design a Type-aware Input Module to adaptively recognize particles of different types and perform feature fusion afterward, such that fluid-solid coupling issues can be better dealt with. Furthermore, we propose a new dataset, Tank3D, to further explore the network’s ability to handle more complicated scenes. The experiments demonstrate that our approach not only attains a quantitative enhancement in various metrics, surpassing the state-of-the-art methods, but also signifies a qualitative leap in neural network-based simulation by faithfully adhering to the physical laws.

Assessment of Goat Milking Training Using Method and Method Demonstration Extension Teaching Methods among Rural Women in Kwara State, Nigeria

Milk, a good source of protein, is inadequate in supply and not affordable for the majority of the rural communities of Nigeria. To increase milk production from available animal resources, extension services have included goat milking training using video and method demonstration in their service delivery packages. This study, therefore, assessed goat milking training using video and method demonstration among rural women in Kwara State, Nigeria. The study assessed the knowledge level of the respondents (rural women who reared goats in their households) on goat milking and the perception of the respondents on goat milking training. An Interview guide was used to collect data after training. Data analysis was done using descriptive statistics and the Kruskal Wallis H test. The findings of the study were that: 58.3% of the respondents had high knowledge of goat milking; women who had a positive perception towards goat milking training conceded that the training is simple and arouse the interest of other women (WMS=2.83); perceived benefits of goat milking training were; readily available milk (( =2.64); and the video extension teaching method at two exposures was most effective, followed by method demonstration at two exposures (χ2 =83291; Pvalue ≤ 0.001). The study concluded that the video extension teaching method at two exposures is most effective and recommended its use in disseminating innovation.

Evaluating the Effectiveness of Expert Modeling Videos on Nursing Student Competency Behaviors.

Expert modeling videos (EMVs) have shown promise in improving students' performance in simulation. However, research evaluating the impact of EMVs is limited to major performance areas, lacking exploration into specific student competency behaviors. This study evaluated the effect of an EMV intervention on undergraduate nursing students' behavioral competencies as measured by the Creighton Competency Evaluation Instrument (CCEI). Using a quasi-experimental pragmatic evaluation design, students in a medical surgical nursing course (n=160) viewed either an expert model demonstration video (experimental) or expert model discussion video (control). Students' behavioral competencies were measured and compared between groups using the CCEI. Students who viewed an expert model demonstration video performed at a higher level of competency in 11 of the 18 CCEI behaviors. Using EMVs in nursing simulation may improve students' ability to achieve clinical competency in nursing specific behaviors.

Smartphone-based straw incorporation: An improved convolutional neural network

In conservation tillage, the effective incorporation of straw into soil is a critical factor for optimizing decomposition rates and addressing challenges related to straw accumulation. Consequently, this study introduces an innovative straw semantic segmentation model to extract straw mixed with soil from images, and proposes a method to measure the quality of straw and soil mixing based on this model. We conducted field experiments based on this method, analyzed the quality of straw incorporation at different depths, and finally integrated the model into a mobile application to facilitate the automatic, accurate, and rapid assessment of the quality of straw and soil mixing. The methodology of this study as an improved convolutional neural network entailed the fusion of deep separable convolution with a multi-scale feature extraction module, utilizing convolution kernels of varying sizes to capture the diverse features of straw. Further refinement included halving the first convolution channel and implementing a direct connection structure. Attention gates were strategically deployed to enhance salient features, resulting in superior accuracy compared to the original U-shaped network, fully convolutional network, and Otsu algorithm. Notably, the proposed model achieved enhanced performance while reducing the number of parameters and model complexity to one-third and one-half of the original U-shaped network, respectively. For a quantitative description of the rate and uniformity of straw incorporation, this study employed image processing technology and a grid counting method. The synergistic integration of smartphone imagery and deep learning expedited the delivery of rapid and reliable results, promising practical applicability in future straw incorporation practices. A demonstration video of the application is accessible at: https://doi.org/10.6084/m9.figshare.14480745.v3. The findings of this research contribute significantly to the advancement of conservation tillage by establishing a robust framework for the assessment and enhancement of straw incorporation operations’ efficiency.

Producing two-dimensional dust clouds and clusters using a movable electrode for complex plasma and fundamental physics experiments.

We report a Bidirectional Electrode Control Arm Assembly (BECAA) for precisely manipulating dust clouds levitated above the powered electrode in RF plasmas. The reported techniques allow the creation of perfectly 2D dust layers by eliminating off-plane particles by moving the electrode from outside the plasma chamber without altering the plasma conditions. The tilting and moving of electrodes using BECAA also allows the precise and repeatable elimination of dust particles one by one to achieve any desired number of grains N without trial and error. Simultaneously acquired top and side view images of dust clusters show that they are perfectly planar or 2D. A demonstration of clusters with N = 1-28 without changing the plasma conditions is presented to show the utility of BECAA for complex plasma and statistical physics experimental design. Demonstration videos and 3D printable part files are available for easy reproduction and adaptation of this new method to repeatably produce 2D clusters in existing RF plasma chambers.

Full title- acceptability and feasibility of HIV self-testing (HIVST) among MSM and transgender women (hijra) in Bangladesh: A mixed-method study

BackgroundHIV testing coverage among males having sex with males (MSM) and transgender women (locally known as hijra) is low in Bangladesh. Oral fluid-based HIV self-testing (HIVST) may improve coverage due to its convenience and privacy but is yet to be tested in Bangladesh. Therefore, the acceptability and feasibility of supervised HIVST was examined. MethodsA cross-sectional study was conducted among 379 MSM and hijra selected from five geographical regions from February–October 2020. Semi-structured questionnaire was used to examine socio-demographics, risk behaviors, and perception to acceptability and feasibility (correct completion) of HIVST. Both bivariate and multivariable logistic regression analyses were performed. Qualitative data collection encompassed in-depth interviews (N = 19), key informant interviews (N = 10), and two focus group discussions (N = 12). Line-by-line content, contextual and thematic analysis were done and triangulated to explore facilitators and challenges of HIVST among MSM and hijra. ResultsAmong 379 participants, the acceptability of HIVST was 99.5 % (n = 377). Reasons for acceptability included interest in independent testing (84.3 %), peer influence (57.3 %), quicker-easier procedure (54.9 %), and painless procedure (52.5 %). Qualitative findings revealed participant's risk perceptions, empowering feelings, social stigma, complementing working hours, and convenience during COVID-19 lockdowns. Around 92 % of the participants correctly completed HIVST. In multivariable analysis, the likelihood of correct test conduction was found higher among metropolitan, younger, married, educated, and participants who felt confident during HIVST process. Qualitative findings underscored the importance of supervising the use of HIVST for first-time users. Participants, particularly the less educated groups, highlighted the video demonstration as a useful tool in the context of difficulties in reading the textual instructions. However, most participants pointed out the result interpretation as the trickiest part of HIVST. All participants demonstrated willingness for future HIVST, were interested in social media-based approaches (84 %), were willing to purchase subsidized kits, and preferred conducting future tests alone at home (83.2 %). ConclusionOral fluid-based HIVST was an acceptable and feasible approach for MSM and hijra in Bangladesh who were willing to do future tests independently after the supervised approach. Willingness to purchase kits and interest for social media-based approaches indicate scalability and sustainability potential of HIVST.

The Effect of Interprofessional Education on Student Readiness for Collaborative Practice.

Health care reform promotes interprofessional patient-centric health care models associated with improved population health outcomes. Interprofessional education (IPE) programs are necessary to cultivate collaborative care, yet little evidence exists to support IPE pedagogy within nursing and other health science academia. This quasiexperimental study examined differences in pre- and posttest Readiness for Interprofessional Learning Scale (RIPLS) scores following an IPE intervention. The IPE intervention consisted of a video presentation and a debriefing session after a simulated interprofessional collaborative patient care conference that introduced baccalaureate nursing and health science students to the roles and responsibilities of clinicians in team-based primary care. Pre- and postintervention RIPLS scores were analyzed. Pre- and postintervention RIPLS scores increased across all subscales, with distinct variation between nursing and health science student subscales. This IPE intervention had positive effects on students' readiness for interprofessional learning. Additional research is warranted to support health science pedagogy.

Undergraduates' comparative assessment, utilizing a structured rubric, of hands-on versus video-supported presentation in class II cavity preparation.

Dental education is considered as a complex, challenging and often stressful educational procedure. Acquisition of psychomotor skills by undergraduate students is an important step in many health professions to become a successful professional. During under graduation, class II cavity preparation exercise is of utmost important in dentistry. To compare class II cavities prepared by students after hands-on live demonstration and pre-recorded video demonstration using well-organised evaluation rubrics. Preclinical dental students (n= 50) were divided into two groups. The students in group I (n= 25) attended a hands-on live demonstration performed by one faculty while students in group II (n= 25) watched a 15-minute pre-recorded procedural video on the projector. Both groups were appealed to prepare class II cavity for amalgam involving disto-occlusal surface of mandibular second molar articulated on jaw model (TRU LON study model, Jayna industries, Ghaziabad U.P., India). Following completion of the preparations, all teeth were collected, and labelled grades of prepared cavities were given according to prespecified rubrics. The data of scores were presented as means and standard deviation. Statistical analysis of data was executed using SPSS software. A paired t-test was used to compare scores between groups. The study shows that the video-supported demonstration of a cavity preparation was better than the live hands-on demonstration. A higher mean response for the procedural video group was found compared to the live demonstration group (p= 0.000133). Pre-recorded video-supported demonstration along with guidance by a tutor may be a viable alternative to hands-on live demonstration in cavity preparation procedures during undergraduate dental training. Moreover, rubric methods can be implemented in the teaching of various preclinical exercises for conservative dentistry and endodontics.

Assessing Knowledge and First-aid Practice Scores of Caregivers of Epilepsy Patients Before and After an Educational Programme in the Kingdom of Saudi Arabia

Background Although epilepsy is one of the most prevalent and severe neurologic disorders, our knowledge of its intricate pathophysiology and skills to manage are still limited. Recognising its early signs and symptoms are crucial skills for caregivers of epileptic patients to acquire. This study was aimed at assessing the effectiveness of an education programme on improvement in the caregivers’ knowledge of epilepsy and first-aid practices. The findings will assist caregivers of children with seizures who frequently experience fear and anxiety relative to their perceived confidence to manage seizures. Education to caregivers could improve their perceived level of self-efficacy. Methods A community-based, pre- and post-intervention survey was conducted at neurologic care clinics across Saudi Arabia. Data were collected using a pretested, semi-structured, interviewer-administered questionnaire. The educational intervention was aimed at disseminating information via a short talk and video demonstration of epilepsy-related first-aid good practices. Data were analysed using SPSS version 21. Results Pre-intervention survey of 586 caregivers revealed that nearly 60% had inadequate knowledge of epilepsy; this was reduced to 23.2% after education. Similarly, 84% of caregivers had inadequate knowledge of first-aid practices before the educational intervention, but this was reduced to 32.4% after that. Having resided in the Western regions was a negative predictor of good first-aid practice knowledge scores, both before and after education. A university degree or higher education was positive predictor of higher knowledge scores both before (T=-4.564; p<0.001) and after education (T=-2.775; p=0.025). The oldest caregivers (>50 years) exhibited a significantly lower mean first-aid practice knowledge score (F=7.771; p=0.001). Conclusion Caregivers’ general and first-aid practice knowledge were generally poor prior to but were both markedly improved after educational interventions. Targeted educational health promotion could bring awareness to those with lower levels of education and older caregivers living in particularly the Western regions of Saudi Arabia. (255 words)

HiSOMA: A hierarchical multi-agent model integrating self-organizing neural networks with multi-agent deep reinforcement learning

Multi-agent deep reinforcement learning (MADRL) has shown remarkable advancements in the past decade. However, most current MADRL models focus on task-specific short-horizon problems involving a small number of agents, limiting their applicability to long-horizon planning in complex environments. Hierarchical multi-agent models offer a promising solution by organizing agents into different levels, effectively addressing tasks with varying planning horizons. However, these models often face constraints related to the number of agents or levels of hierarchies. This paper introduces HiSOMA, a novel hierarchical multi-agent model designed to handle long-horizon, multi-agent, multi-task decision-making problems. The top-level controller, FALCON, is modeled as a class of self-organizing neural networks (SONN), designed to learn high-level decision rules as internal cognitive codes to modulate middle-level controllers in a fast and incremental manner. The middle-level controllers, MADRL models, in turn receive modulatory signals from the higher level and regulate bottom-level controllers, which learn individual action policies generating primitive actions and interacting directly with the environment. Extensive experiments across different levels of the hierarchical model demonstrate HiSOMA’s efficiency in tackling challenging long-horizon problems, surpassing a number of non-hierarchical MADRL approaches. Moreover, its modular design allows for extension into deeper hierarchies and application to more complex tasks with heterogeneous controllers.

A Comparative Study of Parent and Child Perspectives on Using the Intranasal Mucosal Atomization Device for Behavior Management in Pediatric Dental Sedation.

Background Dental anxiety in children often necessitates sedation for effective treatment. Different methods of sedation have proved to be beneficial. However, intranasalsedation provides a needleless, rapid drug delivery method that bypasses hepatic metabolism. Intranasal sedative drugs can be delivered using a mucosal atomization device (MAD). This study aimed to find the opinions, beliefs, and existing knowledge of parents and children regarding intranasal sedation and the method of drug delivery through MAD. Materials and methods The study comprised 50 parents, aged 20 to 50, who came in with a single child, aged five to nineyears. In separate rooms, parents and kids were each shown a video about the use of the intranasal sedation technique with MAD as a pharmaceutical help during routine dental procedures. After the video presentation, each participant was required to complete a pretested self-made questionnaire with 21 questions and multiple-choice options. The chi-square test was used in the statistical analysis of the completed questionnaires (P < 0.05). Paired t-test was used for behavior assessment of the children before and after intranasal sedation. Results A significant correlation between parental socioeconomic status and acceptance of intranasal sedation was observed. Parents with higher education levels exhibited a greater level of acceptance (P = 0.000). Parents whose children had prior dental experiences were more likely to view intranasal sedation as a safe option (P = 0.038). Additionally, a significant proportion of previously sedated children expressed willingness to undergo treatment using intranasal sedation. Evaluation of children's behavior before and after treatment revealed a notable improvement, indicating the effectiveness of intranasal sedation (P = 0.000). Conclusion The study thoroughly investigated how parents and children view intranasal sedation via MAD. It revealed a positive perception of safety and trust among parents regarding this method for pediatric dental procedures.

An abdominal vibration combined with walking exercise (AVCWE) program for older patients with constipation: Development and feasibility study.

Older patients with constipation are at higher risk for inadequate bowel preparation, but there are currently no targeted strategies. This study aims to develop an abdominal vibration combined with walking exercise (AVCWE) program and assess its feasibility among older patients with constipation. Phase I: Using the Delphi technique, eight experts across three professional fields were consulted to develop the AVCWE program. The experts evaluated and provided recommendations on demonstration videos and detailed descriptions of the preliminary protocol. Phase II: A single-arm feasibility study of the AVCWE program was conducted on 30 older patients with constipation undergoing colonoscopy at a tertiary hospital in China. A 10-point exercise program evaluation form and several open-ended questions were used to gather feedback from participants regarding the program. In both phases, content analysis was used to critically analyze and summarize qualitative suggestions for protocol modifications. Based on feedback from the expert panel, the AVCWE program developed in Phase I included two procedures during laxative ingestion: at least 5,500 steps of walking exercise and two cycles of moderate-intensity abdominal vibration (each cycle consisted of 10 min of vibration and 10 min of rest). The feasibility study in Phase II showed high positive patient feedback scores for the program, ranging from 9.07 ± 0.74 to 9.73 ± 0.52. The AVCWE program was developed by eight multidisciplinary experts and was well accepted by 30 older patients with constipation. Study participants believed that this program was simple, safe, appropriate, and helpful for their bowel preparation. The findings of this study may provide valuable information for optimizing bowel preparation in older patients with constipation.
