Influence of Training With Corrective Feedback Devices on Cardiopulmonary Resuscitation Skills Acquisition and Retention: Systematic Review and Meta-Analysis (Preprint)
Authors: Nicolau Abel , Jorge Inês , Vieira-Marques Pedro , Sa-Couto Carla
Published: April 2024

BACKGROUND

Several studies related to the use of corrective feedback devices in cardiopulmonary resuscitation training, with different populations, training methodologies, and equipment, present distinct results regarding the influence of this technology.

OBJECTIVE

This systematic review and meta-analysis aimed to examine the impact of corrective feedback devices in cardiopulmonary resuscitation skills acquisition and retention for laypeople and health care professionals. Training duration was also studied.

METHODS

The search was conducted in PubMed, Web of Science, and Scopus from January 2015 to December 2023. Eligible randomized controlled trials compared technology-based training incorporating corrective feedback with standard training. Outcomes of interest were the quality of chest compression–related components. The risk of bias was assessed using the Cochrane tool. A meta-analysis was used to explore the heterogeneity of the selected studies.

RESULTS

In total, 20 studies were included. Overall, it was reported that corrective feedback devices used during training had a positive impact on both skills acquisition and retention. Medium to high heterogeneity was observed.

CONCLUSIONS

This systematic review and meta-analysis suggest that corrective feedback devices enhance skills acquisition and retention over time. Considering the medium to high heterogeneity observed, these findings should be interpreted with caution. More standardized, high-quality studies are needed.

Specific Features of Internal Waves Manifestation in the Near Mouth Zone of the Danube by High-Resolution Satellite Data
Authors: Medvedeva Alesia , Mikhailichenko Tamara , Stanichny Sergey , Bulatov Vitaly
Published: April 2024

The mechanisms of internal waves manifestation in satellite data of the optical range are considered for the mouth area of the Danube. Three main mechanisms for the manifestation of internal waves are identified - the previously described dynamic (due to a change in the roughness of the sea surface in convergent zones created by a moving internal wave), slick - when surfactants accumulate in convergence zones, and a new one - due to a change in the brightness of the sea surface during modulation internal wave by the scattering layer thickness. Data from the OLI Landsat-8 scanner for 2015-2019 were used for the analysis. It is shown that in different situations, internal waves can manifest themselves either due to various mechanisms, or only due to one of them. Summary maps of manifestations of internal waves in the study area were constructed. Additionally, situations with quasi-synchronous data of MSI Sentinel-2 and C-SAR Sentinel-1, which displayed internal wave packets, are considered. The selection of such pairs made it possible to estimate the phase velocities of internal waves, which ranged from 0.05 m/s (0.19 km/h) to 0.95 m/s (3.43 km/h) in various hydrometeorological situations. Examples of internal wave front transformation on submesoscale eddies are presented
Effects of Source Directivity and Nonlinear Soil Behavior During the January, 1 2024 Noto Earthquake (Mw = 7.5)
Authors: Pavlenko Ol'ga
Published: April 2024

The earthquake of January 1, 2024 with the epicenter at Noto Peninsula of Ishikawa Prefecture, Japan, and the moment magnitude Mw = 7.5 obviously represents an intermediate case between weaker earthquakes with relatively small sources, like the 1995 Kobe and 2000 Tottori earthquakes (Mw ~ 6.7-6.8), showing nonlinear soil response and soil softening (reduction of shear moduli) and stronger earthquakes, like the 2003 Tokachi-Oki and Tohoku earthquakes (Mw ~ 8.3-9.0) with extended sources and source directivity effects, accompanied by soil hardening and generation of high peak ground accelerations (PGA) > 1 g. In this research, based on KiK-net vertical array records (11 sites), models of soil behavior in the near-fault zones of the 2024 Noto earthquake are constructed, i.e. vertical distributions of stresses and strains in soil layers changing with time during strong motion, which showed nonlinear soil response and reduction of shear moduli in the near-fault zones. At the same time, the waveforms of acceleration time histories indicate the effects of source directivity, when seismic waves, radiated by the crack tip propagated along a~rather long section of the fault plane, arrived to remote sites almost simultaneously, overlap, harden subsurface soils and generate high accelerations on the surface, PGA ~ 2828 Gal at remote ISK006 station.
Democracia, imaginación política y soberanía educativa. Una lectura de las escenas fundantes de la pedagogía latinoamericana
Authors: Arata Nicolás
Published: April 2024

Una larga historia entrelaza imágenes con pedagogía. ¿Qué usos puede hacerse de este vínculo para movilizar ideas, argumentos o sentar posiciones político-pedagógicas? La pregunta no es nueva. Las imágenes -advierte Inés Dussel (2010)- se utilizaron desde muy temprano para transmitir memorias, registrar acontecimientos o imprimir referencias perdurables, todas ellas tareas educativas que marcaron el vínculo entre los seres humanos y sus sociedades. Combinar estrategias curatoriales con la elaboración de nuevas narrativas en clave pedagógica permite movilizar ideas para construir posiciones argumentadas, iluminando la actualidad de viejos problemas. En este ensayo apelo a una serie de imágenes para reflexionar sobre las posibilidades de leer en clave pedagógica la historia de América Latina, particularmente en torno a la noción de soberanía pedagógica. Utilizaré la categoría de “escena fundante”, elaborada por Adriana Puiggrós (1995) para enhebrar tres tópicos -a partir de imágenes-, en torno a los cuales configurar una posición políticopedagógica enraizada en las tradiciones críticas del continente. Los fundamentos a los que remiten aquellos tópicos pedagógicos son el principio de la originalidad -contra la idea de réplica o imitación-, el principio de igualdad -como fundamento irrecusable de una pedagogía orientada al bien común-, y el principio político del que debe ser portador una pedagogía que aspira a desnaturalizar las desigualdades y formar sujetos comprometidos con la defensa de la democracia y de la educación como derecho
Dejar hacer o hacer para dejar: escenarios de la universidad en América Latina y el Caribe
Authors: Didriksson Axel
Published: April 2024

La tendencia a mantener una organización académica e institucional que se vuelve cada vez más obsoleta y genera cambios de forma muy lenta, en la gran mayoría de las universidades de América Latina y el Caribe, tiene como explicación, en este trabajo, la reproducción de dos escenarios que se mantienen y se prolongan en el tiempo: uno, el del cortoplacismo y el otro el de la mercantilización, desde sus distintas variantes y en medio de profundas desigualdades que se ciernen sobre estas instituciones, en el marco de los contextos sociales en los que se desarrollan. Desde esta postura crítica, se abordan las características que han mantenido las universidades en la región, pero se presenta, de manera contrastante, otro escenario en el que se están organizando alternativas a la lógica de la reproducción de la segmentación y la desigualdad, y que ha permitido emprender nuevos caminos en la producción de conocimientos, en la investigación con incidencia social, en el mayor compromiso de las universidades respecto de su intervención en el mejoramiento de las condiciones de vida y de bienestar de importantes sectores de la población, tanto por sus esfuerzos a favor de la inclusión social, como por su reorientación hacia nuevas áreas del conocimientos, redes, asociaciones de colaboración académicas y científicas, que presentan una visión emergente pero promisoria en el ámbito de las instituciones de educación superior.

Published: April 2024

Abstract: Handwriting recognition of medical prescriptions has been a challenging problem over the recent years with constant research in providing possible accurate solutions. Indecipherable handwritten prescription and inefficiency of Pharmacist to understand the medical prescription can lead to serious and harmful effect to the patients. Even in the recognition of handwriting, mainly doctors notes, they are very difficult for everyone to understand and it takes time for a person to analyse it. So, this idea mainly focused on interpreting doctor’s notes using handwritten recognition and deep learning techniques. The handwritten or printed document pictures are transformed into their electronic counterparts using an optical character recognition (OCR) system. Due to individuals' inconsistent writing styles, dealing with handwritten texts is significantly more difficult than dealing with printed ones. Handwritten text recognition could be done by Image processing, Machine Learning or Deep Learning Techniques. Out of these Deep Learning remains to be the most popular and prominent. Some of the Deep Learning techniques includes Recurrent Neural Networks (RNNs) and Convolutional Neural Networks (CNNs). This gives a review of the various recognition methodologies used for interpreting handwritten texts. It includes the most important algorithms that could be used for detecting the handwritten word/text/character by using various approaches for the recognition process. In the end we are thus comparing the accuracies provided by these systems.

Authors: Farheen Sayeeda Arshiya , R Navaneetha
Published: April 2024

Abstract: Microgreens, the young seedlings of vegetables and herbs, are gaining popularity for their distinct flavors , superior nutritional content and positive impact on gut health. Red cabbage microgreens (RCMG) stand out with remarkable vitamin C (147mg/100g) and other antioxidant rich phytochemicals content. Flax seeds (FS), known for their versatility in food offer cardiovascular benefits with high levels of alpha-linolenic acid and dietary fiber. This study aimed to develop value-added cheese spread using RCMG and FS, employing pre-preparation treatments like blanching and roasting. Three variations (V1, V2, V3) with varying RCMG and FS compositions were developed and evaluated. Commercially available cheese spread was used as the control (basic). Sensory evaluation, conducted by 46 semi-trained panelists using a 9-point Hedonic rating scale, revealed V1 (RCMG-30%, FS-6%) as the most accepted variation with good spreadability compared to the basic cheese spread. Value-added cheese spread showed no signs of spoilage in 30 days shelf life check under refrigeration. This study indicates the successful incorporation of Red Cabbage microgreens and Flaxseeds into the cheese spread with good sensory acceptability.

Authors: Fitri Rahmadhani , Lufri L. , Alberida Heffi , Amran Ali , Fachry Rifani
Published: April 2024

Currently, students tend to be less innovative and creative in learning and its implementation in everyday life. Project-Based Learning (PjBL) is a learning strategy oriented towards contextual problem solving to find solutions based on the experiences of students so that they can be more creative and innovative. This research aims to reveal how PjBL contributes to increasing student creativity. This research was conducted with a literature review of articles in international journals, international seminar proceedings, and SINTA accredited journals. Based on the results of the analysis carried out, it was found that to realize high creativity, the PjBL model is one of the best solutions to increase students' creativity. This learning model is able to make students more creative and innovative in solving every problem in everyday life by following PjBL syntax. PjBL is suggested to be an alternative for educators to train and foster the formation of students' creativity. It can also be concluded that PjBL can train and increase student creativity because the syntax of this learning model allows students to explore, create, interpret and develop products resulting from their projects.
The Role of Women in Political Contestation in Indonesia: An Analysis of the Political Ideas of Ali Abdur-Raziq
Authors: Mahendra Moh. Lutfi
Published: April 2024

This article discusses the potential of women in political contestation from the perspective of Ali Abdur Raziq, a leading Islamic thinker and reformer. The growth of the population, which is dominated by women, makes them a force in their own right. However, awareness of women's contributions to politics is still minimal. This view is supported by historical facts which show men as characters who dominate all aspects of life, so that narrating women and politics in the same conversation is almost considered something taboo. The purpose of writing this article is to re-present women as figures who stand the same as men, having the same opportunities in every matter. By using literature research, this article hypothesizes that women, while still carrying their religious awareness, have the potential to help change the country and society's views through political aspects
“Eu tenho a fama de ser um pouco transgressora!”: perspectivas interseccionais de enfermeiras negras
Authors: MATHIAS P. P. , MATTOS A. R.
Published: April 2024

This study used the theoretical-methodological framework of intersectional and decolonial feminisms, conceiving the need to problematize discrimination/oppression of gender, race, class, professional training and others, as phenomena in the field of social psychology. The objective of this study was to analyze the perception of self-declared black nurses regarding the hierarchies of knowledge and power in health care work. Seven nursing professionals who work/have worked in hospital units of the SUS in the State of Rio de Janeiro from March 2020 to the moment of the fieldwork were interviewed. The results were divided into two analytical categories: 1.“The Doctor is the demigod!” and the “Doctor without a doctorate!”; 2. Knowledge-power hierarchies and racial relations in health. The results showed that according to their perception, the medical category still exerts a discursive hegemony mainly in general hospitals and psychiatric hospitals. Nurses who hold a managerial/leadership position reported experiences of discrimination linked to gender, race, professional class, among others, and that they react to these through a posture of confrontation and fight against racist and sexist structures. It was concluded that the research shows the importance of questioning the socio-sexual and racial division of work in health and its implications, of acknowledging the protagonism to black women in research, and also the importance of the role of these women within health care in the SUS.
Type parameter estimation of 2D-GTD model based on ADMM approach
Authors: Jin Mingming , Wang Jun , Wei Shaoming , Zeng Zhiqiang , Chi Zhang , Qu Fangrui
Published: April 2024

The type parameter helps in the scattering mechanism analysis and
scattering center identification. However, current approximate solution
methods based on spectral estimation are noise-sensitive and have poor
accuracy. In this letter, a high-precision approach for the type
parameter based on the alternating direction method of multipliers
(ADMM) is proposed. We use logarithmic transformation to separate the
type parameter and the amplitude from the coupling term, and initially
obtain the closed-form solution of the type parameter. Then, the
regularization term of l2-norm is used for denoising. Finally, a joint
optimization model based on ADMM is constructed to effectively estimate
the type parameter. Simulation results confirm the high accuracy of the
proposed approach.
Volcanic Earthquake Classification using Transformer Encoder and Its Interpretability Evaluation
Authors: Suzuki Yugo , Yukutake Yohei , Ohminato Takao , Yamasaki Masami , Kim Ahyi
Published: April 2024

Precisely classifying earthquake types is crucial for elucidating the
relationship between volcanic earthquakes and volcanic activity.
However, traditional methods rely on subjective human judgment, which
requires considerable time and effort. To improve this, we developed a
deep learning model using a transformer encoder for a more objective and
efficient classification. Tested on Mount Asama’s diverse seismic
activity, our model achieved high F1 scores (0.876 for tectonic, 0.964
for low-frequency earthquakes, and 0.995 for noise), equivalent to or
better than other methods. According to the attention weight
visualization, our model focuses on critical seismic signal features for
classification, similar to expert analysis. However, it has been
demonstrated that removing subjective elements and employing
standardized labeling of the training data based on waveform features
are necessary to enhance the interpretability of the model.
Additionally, the analyses suggest that stations near the volcanic
crater are essential for a highly interpretative and accurate
classification.

Authors: Bratke Heiko , Biringer Eva , Ushakova Anastasia , D Margeirsdottir Hanna , Janne Kummernes Siv , R Njølstad Pål , Skrivarhaug Torild
Published: April 2024

Objective: To evaluate, from 2013 to 2022, how HbA1c, the incidence of acute complications, and use of diabetes technology changed at the national level in Norway and how glycemic control was associated with use of diabetes technology, carbohydrate counting, or the participation in a quality improvement project.

Research Design and Methods: This is a longitudinal observational study, based on 27,214 annual registrations of 6,775 children from the Norwegian Childhood Diabetes Registry from 2013 to 2022. Individuals aged >18 years, those with diabetes other than type 1, and those without HbA1c measurements were excluded. The outcome measure was HbA1c. The predictor variables in the adjusted linear mixed-effects model were (1) the use of diabetes technology, (2) the use of carbohydrate counting for meal bolusing, and (3) whether the patient’s diabetes team participated in a quality improvement project.

Results: Mean HbA1c decreased from 8.2% (2013) to 7.2% (2021), and the proportion of youth reaching an HbA1c <7.0% increased from 13% (2013) to 43% (2022). Insulin pump use increased from 65% (2013) to 91% (2022). CGM use increased from 34% (first recorded in 2016) to 97% (2022). Insulin pump, CGM, and carbohydrate counting were associated with lower HbA1c and higher achievement of glycemic targets. Girls had higher mean HbA1c than boys. Mean HbA1c levels were lower in clinics that participated in a quality improvement project for the following four years after the project.

Conclusions: Diabetes technology, carbohydrate counting, and systematic quality improvement in pediatric departments led to improved glycemic control.

Published: April 2024

Background and purpose: This large population-based, retrospective, single-center study aimed to identify predictive factors in patients with brain metastases (BM) from gynecological cancers.
Material and methods: 144 patients with BM from gynecological cancer treated with radiotherapy were identified. Primary cancer diagnosis, age, performance status, number of BM, presence of extracranial disease and type of BM treatment were assessed. Overall survival (OS) was calculated using the Kaplan-Meier method and Cox proportional hazards regression model was used for multivariable analysis. A prognostic index was developed based on scores from independent predictors of OS.
Results: Median OS for the entire study population was 6.2 months. Forty percent of patients died within 3 months after start of radiotherapy. Primary cancer with the origin in cervix or vulva (p=0.001), ECOG 3-4 (p<0.001) and the presence of extracranial disease (p=0.001) were associated with significantly shorter OS. The developed prognostic index based on these factors, categorized patients into three risk groups with a median OS of 13.5, 4.0 and 2.4 months for the good, intermediate and poor prognosis group, respectively.
Conclusion: Patients with BM from gynecological cancers carry a poor prognosis. We identified predictive factors for survival and developed a scoring tool to help differentiate patients with better or worse prognosis. Patients in the high-risk group have a particular poor prognosis, and omission of radiotherapy should be considered.

Project Management: An Objective Assessment of Activity Duration
Authors: AM* Aliyu
Published: April 2024

We propose and test an improved method for project evaluation and review. This method would reduce the subjectivity and uncertainty regarding the anticipated start time of the proposed activity. This is accomplished by running the threetime estimate through a normality test. The accuracy and objectivity of activity time estimation would both be enhanced by this technique. Nevertheless, the results of the proposed PERT approach for activity and project durations, variances, and project duration probability were similar to those of classic PERT when multiple project networks were studied. Eliminating uncertainty in activity time estimations from project evaluation review techniques is the aim of this paper. All three of the time estimates are shown to be regularly distributed by the data. This work’s novel approach is the first to resolve un- certainty in activity time estimation.

An Extensive Analysis of Natural Bioenhancers: A Review
Authors: DS* Salman
Published: April 2024

The concept of bioavailability enhancer is new to the modern system of medicine. Basically, this concept originated in Ayurveda and being used in this system of medicine since centuries. Chemical substances known as "bioenhancers" work to increase the bioavailability of medications when they are combined with them and do not have a synergistic impact on the drug. The bio‑enhancement leads to reduction in therapeutic dose of principal drug, thus reducing the possibilities of toxicity and side effects of drug, potentiating the efficacy, reducing the resistance, decreasing the requirement of raw material for drug manufacture, and ultimately benefitting to the world economy by reducing the manufacturing cost. A bioenhancers do not introduce its own therapeutic action with the actual active effect at the therapeutic dose used. Herbal bioenhancers are derived from both plant and animal origins. The compounds from plant origin majorly used as a bioenhancer are piperin, naringenin, niaziridin, quercitine, aloe, etc.

This research uses Human-Computer Interaction methodologies such as participatory design and iterative prototype evaluation to effectively design technology for people in the rural areas of Punjab, Pakistan.Many participants in this PhD research have a low literacy level, making it challenging for them to obtain the knowledge necessary to manage their common chronic health conditions, such as diabetes. The remoteness of these participants, the lack of transport, and the internet inaccessibility only exacerbate this healthcare self-management. The research focused on designing an Interactive Voice Response system using participatory design methodologies.Interactive Voice Response (IVR) is an accessible method of transmitting knowledge because it allows voice-based interaction. To assist illiterate populations in managing chronic health conditions, hierarchical IVR systems are currently being developed and pose the challenge of navigating a large amount of information with hierarchy. Therefore, using a phone number-specific profile, this project iteratively develops a dynamic IVR that adapts information presen-ted to people with diabetes to compensate for some of their challenges in healthcare support. Multiple design studies and deployments are conducted to validate the IVR system.The IVR system was designed iteratively using Participatory Design (PD) to explore users’ pref-erences. Although PD originated in Scandinavia, it poses several challenges since it assumes literacy and a cultural mindset associated with the Global North. Hence, it is necessary to adopt democratic, patient-centred, iterative participatory approaches to develop a comprehensive understanding of PD in a diverse and challenging environment, including both urban and rural contexts. Several PD techniques were used, including Wizard of Context, Narrative Scoping with Personas, an interactive framework that used videos, pictures and audio, and iterative PD.After deploying the IVR system using servers built on the Asterisk platform, the system’s usefulness for keeping people with diabetes informed about their condition and better managing their condition was demonstrated by gathering qualitative and quantitative data.

Critical thinking skills are the ability to solve problems and make decisions when facing a problem. Critical thinking skills can consist of the ability to analyze, interpret, evaluate, summarize, and synthesize various information to prevent negative impacts from occurring. The purpose of this study was to describe and identify students' critical thinking skills. The method used in this research is descriptive quantitative method. Data were collected through survey techniques in the form of questionnaires using test instruments. The results of this study are the average level of students' critical thinking skills at 54.75%. One of the efforts to improve students' critical thinking skills is to apply a problem-based learning model. This is in line with the purpose of science learning, which is to develop student’s' thinking skills in the learning process so that they can apply natural science concepts in their daily activities.

Nitrogen (N) from agricultural systems contributes to the eutrophication of waterbodies through leaching. Incorporating organic material with a high carbon-to-nitrogen (C/N) ratio, such as mixed pulp mill sludges (PMSs), into the soil in autumn could reduce the amount of leachable N. This study tested the potential of composted and lime-stabilised mixed PMSs (CPMS and LPMS) in reducing the concentration of mineral N in the soil, and thus the risk of N leaching from arable land in the boreal region using a two-year field experiment. To better understand the mechanisms of the PMSs for influencing mineral N concentration in soil, the impact of PMSs with different quality on the reactions of N in the soil was investigated in a laboratory incubation study. In the field experiment, nitrate-N (NO3--N) concentration was lower with PMSs compared to mineral fertilisation and the control during the first autumn and the following spring after PMS application. The undersowing of Italian ryegrass reduced the NO3--N concentration in the soil during the first autumn. In the incubation experiment, PMSs reduced the soil ammonium-N (NH4+-N) concentration at the beginning of the experiment and the soil NO3--N concentration throughout the experiment compared to a mineral fertiliser treatment and an organic fertiliser. Increased soil respiration in PMS-treated soils indicated increase in microbial activity, and thus immobilisation of soil NO3--N and NH4+-N due to PMSs addition. These results suggest that PMSs have the potential to reduce N leaching from agricultural soils. However, the immobilisation of N must be considered when planning the nutrient requirements of the following crops.

The introduction section of a research article (RA) is crucial, as it serves as the foundation for the entire research study. A well-crafted introduction can captivate readers, offering essential insights into the background and rationale for the study, while also conveying the research's quality and reliability. This study investigates how novice versus experienced social science researchers introduce their work in English research articles (RAs) published in internationally recognized Scopus-indexed journals compared to those published in Indonesian national journals. We analyze the rhetorical structure and linguistic features used in these introductions. Employing Swales' (2004) Create A Research Space (CARS) model as a theoretical framework, this descriptive comparative qualitative study delves into the analysis of commonalities and differences in the execution of rhetorical moves and steps, as well as linguistic features and metadiscourse. The results reveal that both sets of data exhibited all three rhetorical moves outlined in the CARS model, namely Move 1 (Establishing a Territory), Move 2 (Establishing a Niche), and Move 3 (Presenting the Current Work). However, the findings also underscore distinctions in how these steps and metadiscourse were realized, indicating that writers in both groups employed distinct approaches when introducing their research studies. Implications to English teaching at universities and publication workshops are discussed.

Objectives: To investigate the effect of botulinum toxin-A (BoNT-A) on the age groups and gross motor function classification level in children with cerebral palsy (CP).Method: In this study, 116 children with spastic CP were investigated. BoNT-A was injected into the spastic muscles of the lower limbs of all participants. All participants received physiotherapy and functional electrical stimulation for 3 months after injection. We measured the change in spasticity using the Modified Ashworth Scale and gross motor function using the GMFM-88. Spasticity was measured before injection and at 1 and 3 months after injection. Measurement of gross motor function was performed before and after the injections. Results: The effect of BoNT-A injection in combination with physiotherapy and electrical stimulation significantly improved spasticity and gross motor function. After BoNT-A injection, younger children showed reduced spasticity and improved gross motor skills compared to older children. At the gross motor level, sitting, standing, and walking improved in children with gross motor function classification levels I-III, and posture and mobility improved in children with gross motor function classification levels IV-V.Conclusions: We conclude that BoNT-A injection is effective for improving gross motor function in patients younger than 72 months of age.
