Published: May 2024

Purpose: Interprofessional education is a foundational component of many health professions educational programs as it contributes to the goals of the Quadruple Aim by prioritizing collaborative and streamlined quality healthcare. Furthermore, student engagement in interprofessional educational activities provides opportunities to better understand their own and others’ health profession disciplines. The purpose of this project was to utilize Canadian Interprofessional Health Collaborative (CIHC) to evaluate a framework for student engagement in a community-engaged project focused on reducing barriers to care in people living with type 1 diabetes in rural communities. Methods: As members of an interprofessional, type 1 diabetes, community-engaged research team, students from various graduate and pre-health professions programs participated a variety of activities as research assistants to increase their competency as future healthcare practitioners. These activities included research capacity building, interprofessional collaborations, patient and community interactions, and interprofessional healthcare research. Utilizing the CIHC Framework, the learners reflected and assessed their interprofessional competency, growth, professional identify, and understanding of interprofessional collaboration while providing suggestions for future students participating in interprofessional health sciences research. Findings: Learners found the CIHC to be a robust tool for reflecting on their abilities to provide care in an interprofessional team. The community engagement projects heightened their abilities in role clarification, team functioning, and collaborative leadership which were determined by the group to be some of the most essential skills for entering an interprofessional healthcare workforce. Conclusions: Use of the CIHC framework was an effective method to guide learner progress in developing interprofessional skills within a community engagement project. Reflection on achievement of CIHC domains assists learners in identification of growth in professional identity and understanding of interprofessional collaboration.

Published: May 2024

Purpose: Burnout continues to be an important concern for athletic trainers working in the collegiate sport setting. The purpose of the study was to examine the relationships between working hours, sleep, and burnout among athletic trainers providing patient care in the collegiate setting. Methods: A web-based (Qualtrics, Provo, UT) cross-sectional study using a self-reported questionnaire was used to collect demographics and data on working hours, sleep, and burnout. The Copenhagen Burnout Inventory (CBI) was used to determine burnout. Results: The mean age of our participants (n=1006) was 33 ∓ 9 years; 37.6% (n=378) were male, 61.5% (619), and 1.1% (n=9) chose not to identify. Participants reported moderate burnout (61.55 ± 12.59) on the CBI, additionally a mean score of 66.41 (± 13.42) on the personal-related subscale, 63.91 (± 13.35) on the work-related subscale, and 53.94 (± 19.75) on the client-related subscale. Working more than 50 hours per a week caused collegiate athletic trainers to experience higher levels of personal and work-related burnout (67.34 (± 13.30) and 64.86 (± 13.64) respectively) as compared to those who worked less than 49 hours per week (63.54 (± 13.40) and 60.95 (± 11.96) respectively). Participants report an average of 6.77 (± .95) hours of sleep per night. Those who report less than 6.9 hours of sleep per night scored a mean of 70.48 (± 13.58) on the personal-related subscale, whereas those who report more than 7 hours of sleep per night scored a mean of 63.97 (± 12.71). Conclusions: Overall, athletic trainers in the collegiate setting are experiencing moderate levels of burnout. Athletic trainers who worked over 40 hours a week and slept less than 7 hours per night had higher levels of burnout. Sleep is an important factor in recovery and likely a strategy to prevent burnout.

Published: May 2024

Purpose: For the purpose of this study a peer visitor is being defined as someone who has experienced some type of limb loss and is now mentoring other amputees. Their focus is on health and recovery as opposed to illness as they listen, provide emotional support, and most importantly inspire hope in an individual who has experienced a new amputation. The primary purpose of this study is to examine the reports of amputees regarding their personal experiences related to whether they spoke with a peer visitor following surgery. The study focuses on the benefits of peer visitation and how it impacts rehabilitation outcomes. Methods: This study utilizes a qualitative methodology, and in response to the research questions the benefits of phenomenological research will provide thoughtful and compelling representations of the different lived experiences from all participants. The sample for this study was drawn from across the U.S with the assistance of a local Hanger Inc. clinic, and the Amputee Coalition of America. The primary data collection tools for the investigation were in-depth, audiotaped interviews and a pre-interview questionnaire. All interviews were conducted either over the phone or through a Zoom platform. Results: Findings revealed that peer visitation improves coping strategies for anxiety and depression following surgery, increases confidence and hope in the patient, and influences mental health recovery. Conclusions: Based on the findings it was concluded that a peer visitor will improve overall mental health, improve patient attitudes, and overall improve rehabilitation outcomes for new amputees, and it is plausible to generalize these conclusions to the entire population of amputees. This study empowers new amputees and healthcare practitioners with knowledge to seek out a peer visitor following surgery, as it can improve the outcome of the patient’s rehabilitation.

Authors: Cartagena Mario Armando Beteta , Revuelta Francisco Ignacio Domínguez , Pedrera María Rodríguez , Soria Edith Valencia
Published: May 2024

This investigation forms part of a doctoral study that examines the relation between socioemotional competencies (SECs) and teachers’ beliefs on the integration of information and communication technologies (ICTs). It addresses religion teachers’ knowledge of SECs during the curricular integration of ICTs, specifically their internal aspects in their pedagogical practice using ICTs (second-order barriers). This study also discusses the characteristics of religion teachers, who have received less attention than teachers of science, language, or mathematics disciplines, partly because religion is not considered a priority area in educational policies. To this end, this study adopted a qualitative approach in the phenomenographic tradition to describe how people experience the phenomena in their environment. The informants were 22 religion teachers from Metropolitan Lima, Peru, who participated in in-depth interviews to clarify their emotional experience with ICTs. The results confirmed the empirical findings of contemporary scientific literature and indicated that teaching with ICTs offers a permanent emotional experience manifested in the planning and development of learning sessions as well as in decision-making for pedagogical purposes. The findings allow for feedback and serve as a catalyst for perseverance and work engagement. However, the informants expressed their desire for better training to carry out quality teaching–learning processes with ICTs in religious education.

This study dealt with the influence of process skills and attitude towards Science as contributing factors to cognitive performance among Special Science Class students in Lorenzo S. Sarmiento Sr. National High School. The primary goal of the study was to determine the level of process skills, attitude towards Science, and cognitive performance in terms of their respective indicators, the significant difference between process skills and cognitive performance, attitude towards Science and cognitive performance, and what domains of process skills and attitude towards Science substantially influenced cognitive performance. Also, this study utilized a quantitative, non-experimental design with 166 respondents among Special Science Class students in Lorenzo S. Sarmiento Sr. National High School. The average weighted mean, Pearson r, and multiple regression analysis were the statistical tools used in this study. The study concluded that the level of process skills was high, which meant that process skills among Special Science Class students were often manifested; the level of attitude towards Science was also high, except for the family model indicator, which was observed to sometimes manifest; and the level of cognitive performance was also high, which meant that it was often manifested by Special Science Class students. Moreover, there was a significant relationship and high correlation between process skills and cognitive performance, and the same was true of attitudes towards Science and cognitive performance. For regression analysis, in Science process skills, there were six domains that influenced cognitive performance: observing, measuring, and using numbers; making inferences; predicting; communicating; and using time-space relationships. In attitude towards Science, all domains were influenced by cognitive performance, namely, Science is fun, classroom teacher, self-directed efforts, and family model. However, there was only one indicator in Science process skills that did not influence cognitive performance, and this was the classifying. Furthermore, the overall level of process skills and attitude towards Science as contributing factors to cognitive performance among Special Science Class students in Lorenzo S. Sarmiento Sr. National High School was high. Thus, teachers should implement strong, diverse teaching methods that cater to various learning styles, and parents should help them in their Science-related work. With this, Special Science Classes could create a conducive environment that nurtures the development of Science process skills and fosters a positive attitude towards Science, ultimately enhancing students’ cognitive performance in the discipline.
Engineering Geological Study of Road Tunnel Along Siddhartha Highway Between Butwal and Dobhan Siwaliks Group, West-central Nepal
Authors: Sharma Bishwas , Ulak Prakash Das
Published: May 2024

The Siddhartha Highway is a critical economic artery in Nepal, providing a vital trade link with China and India. However, this roadway has been beset by the frequent occurrence of rock falls and dry landslides, which can cause severe damage and disruption. The main causes of these issues are differential weathering patterns of the rocks, activation of the Main Frontal Thrust (MFT), and a young mountain chain with fragile geology. Because of road instability, the road tunnel has been proposed to prevent damage. The proposed tunnel road passes between the chainage of 29+000 and 30+370 in the rocks of the Lower and Middle Siwaliks. The Lower Siwaliks are composed of thick to thin-bedded shale, mudstone and calcareous sandstone whereas the Middle Siwaliks are represented by presence of friable sandstone, shale and mudstone. The rock mass of this section varies from poor rock to extremely poor rock with RMR values ranging from 29 to 45 and Q values ranging from 0.19 to 1.11. The support system for each class is derived according to RMR and Q-value. The kinematic analysis reveals the potential of wedge failure at the southern portal of the road tunnel, whereas the northern portal has shown a low potential for failure.

Contract Governance, Uncertainty, and Project Performance: Evidence from Water Environment Public–Private Partnerships of China
Authors: Qian Jiuling , Cao Fuguo
Published: May 2024

A public–private partnership (PPP) contract is a long-term procurement contract between the government and private sector, which inevitably faces uncertainties. Existing studies have shown that uncertainty has a significant negative impact on project performance. Some strategies to deal with uncertainty have been proposed; however, they lack systematic attention to PPP contract governance. This paper builds a theoretical framework of PPP contract governance under the constraints of “behavior and environment” through the derivation of classic theories. The framework includes four theoretical variables: output-based specification, good-faith cooperation, flexibility, and public interest protection. The theoretical framework was tested empirically based on data from 368 respondents of a set of survey questionnaires regarding water environment PPP projects. Results reveal that the four theoretical variables are an organic unity and that PPP contract governance and its four dimensions have a positive impact on project performance. Meanwhile, this paper uses the NVivo12 quantitative analysis tool to identify the PPP mechanism: PPP contract governance promotes project performance through the prevention and reduction of behavioral, environmental, and semantic uncertainties. These findings provide evidence from the context of developing countries, such as China, for the improvement of PPP contract governance theory. Moreover, these findings contribute empirical experience and wisdom from contract governance theory to the improvement of long-term project performance.

Nail bed trauma reconstruction and artificial nail replacement – a case report
Authors: Woznica Vlastimil , Třešková Inka , Soukup Martin
Published: May 2024

Nail bed reconstruction is crucial after fingertip trauma, impacting both function and aesthetics. In this article, the authors describe a case of partial distal phalanx amputation of the index finger with laceration of the nail bed’s remaining part. A traumatically elevated skin-fat flap covered the exposed bone on the fingertip, preserving finger length and sensitivity on the radial side. A full-thickness skin graft from the forearm closed a secondary defect on the finger pulp. Nail bed suturing prevented scarring and nail deformity, and a temporary artificial plastic nail replacement maintained the nail bed’s shape. Temporary artificial nail replacements protect the regenerating fingertip bed, promote healing, and prevent nail deformities. Proper adaptation of lacerated nail bed edges, supported by either the patient’s own nail or a temporary artificial nail, is crucial for optimal fingertip restoration, including proper nail shape.

Photorealistic simulation platform for autonomous landing of fixed-wing aircraft
Authors: Xue Weili , Sun Zhen , Ma Kehui , Pei Ling
Published: May 2024

To investigate the vision-based autonomous landing of fixed-wing aircraft, we propose a photorealistic simulation platform that leverages ROS, Unreal Engine, and Pixhawk 4. This platform adopts a software-in-the-loop model consisting of rendering, control, communication, and sensor modules. To achieve realistic rendering control, the seawater hydrodynamics and fixed-wing aircraft dynamics are modeled. Based on the platform, we create simulation scenarios under different weather and disturbance conditions for autonomous landing of the aircraft carrier. The platform solves the problem that datasets of related scenes are difficult to collect and experiments are difficult to carry out. To verify the developability of the platform, we design and implement a runway line feature point extraction method (vision-based pose estimation algorithm), and evaluate the performance of the method under various conditions. Experiments show that our software-in-the-loop platform enables vision-based algorithm verification and supports simulation research for the autonomous landing of fixed-wing aircraft.
Performance assessment of the generalized DIA estimators applied in GNSS positioning
Authors: Yang Ling
Published: May 2024

This paper discusses the performance assessment of the generalized DIA estimators. Based on the unifying framework of the DIA estimators introduced by Teuniseen (2018), quality control indices from three aspects are discussed and formulated, to measure the confidence levels of the testing decisions, to evaluate the reliability of the specified alternative hypothesis models, as well as to compute the biasedness, dispersion and integrity of the estimated parameters under an unconditional case,by taking the uncertainty of the combined estimation-testing procedure into account and performing the propagation of uncertainty accordingly. With a dual-constellation GNSS single-point positioning example, the quality control evaluation of and comparisons among three conventional used DIA estimators are demonstrated for practical applications.

Authors: Kong Weiyu , Zhang Ya , Chang Jiachong
Published: May 2024

An accurate fault detection method is critical in preventing the integrity of integrated navigation system from the abnormal measurements which may occur any time. Here, a genetic algorithm optimization for deep belief network fault detection method is proposed, where the system measuring residuals sequence is used as the input, and the output is the system operating state, such as normal or fault types, in pointwise. The proposed technique extracts the features with various scales, which contain both the local and the general information of the signal sequence, for making a comprehensive and precise classification. To show the validity of the proposed method, simulations based on INS/GNSS integrated navigation system are carried out. The simulation results show that the proposed fault detection algorithm and method is superior to the existing algorithms on the faults detection rate and false alarm rate, and thus, system reliability and navigation precision have been greatly improved.
Multi-GNSS RTK positioning with integer ambiguity resolution: from double-differenced to single-differenced
Authors: Mi Xiaolong , Zhang Baocheng , Yuan Yunbin
Published: May 2024

The development of global navigation satellite systems (GNSS), especially BeiDou navigation satellite system with global coverage (BDS-3), has brought benefits for high-precision positioning. Real-time kinematic (RTK) positioning based on double-differenced (DD) observations has been widely used in high-precision positioning as common errors are eliminated. However, the biases at the receiver-end, which can be dynamically constrained, are also eliminated during the DD process. Therefore, it makes sense to turn RTK from DD to single-differenced (SD) as the advantages of dynamic constraints of the receiver biases can be exploited. In this contribution, we first present RTK models based on DD observations suitable for short, medium and long baselines. Then, based on SD observations, the full-rank RTK models are constructed with the S-system theory. Using observations from GPS, BDS-3 and Galileo, we first demonstrate the short-term stability of receiver-related biases. The SD RTK positioning performance with the stability of those receiver-related biases regarding integer ambiguity resolution success rate and positioning accuracy are analyzed. With those biases, RTK can achieve high performance, and this is more advantageous in multi-GNSS scenarios.
Global and Regional Consistency of VTECs Inversed by IPM and GNSS
Authors: Fu Yunri , Yang Ling , Fu Liping , Peng Ruyi
Published: May 2024

The ionospheric photometer (IPM) onboard the Fengyun-3D satellite is the first optical remote sensing payload in China designed for space-based surveillance of the ionosphere and capable of inversing the Vertical Total Electron Content (VTEC) at night with high sensitivity. Using the VTECs inversed by IPM, along with other sources of ionospheric observations, such as the ground-based Global Satellite Navigation System (GNSS) VTECs, ionospheric modeling can be established based on multi-source space observation techniques and is expected to improve the modeling accuracy in marine areas. Before the ionospheric modeling using multi-source data, the consistency between different sources of VTECs should be analyzed. However, the consistency between the IPM-VTEC and GNSS-VTEC has not been adequately investigated. The authors employ the Global Ionospheric Map (GIM) products from the International GNSS Service to assess the global-scale consistency between them, and the analysis reveals a generally high global-scale consistency, yet the IPM-VTEC values in specific regions are too large due to the influence of auroras and ionospheric equatorial anomalies.

Dichlorvos (DDVP) is an organophosphate insecticide known to cause oxidative stress, which can have a number of negative public health consequences. Harungana madagascariensis (HM), also known as dragon blood tree/amuje, is a plant with antioxidant and anti-inflammatory properties found to reduce oxidative stress in a variety of scenarios. In this study, we looked at the ability of HM stem bark extract to reduce subchronic DDVP induced oxidative stress in rats. Forty (40) Wistar albino rats were randomly assigned into polyphenylene cages Eight (8) per cage in five groups namely; control (group 1), group 2 (DDVP exposed), and treatment groups (groups 3, 4, 5 ‘DDVP exposed’ + 50 mg/kg, 100 mg/kg, 150 mg/kg extract, respectively). Male rats were treated with DDVP (10 mg/kg b.w) except for the control. Both the stressor/toxicant and extract were administered orally throughout the study duration of 28 days. At the end of the study, rats were sedated with chloroform, and blood and organ samples were collected for biochemical analysis. Biomarkers of oxidative stress, such as SOD, CAT, GPx, MDA, and NO, were meticulously evaluated in liver, kidney, and serum. Hormonal indicators, such as FSH, LH, and TES, were assessed in serum too. The result revealed that HM stem bark extract has antioxidant and anti-inflammatory properties that can protect against subchronic DDVP-induced oxidative stress. The extract also influences increased SOD, CAT, and GPx activity and decreased MDA and NO levels in DDVP exposed rats’ liver, kidney, and serum. Additionally, it decreased FSH, LH, and TES levels in DDVP-exposed rats suggesting a potential hormonal protective property. The results are indicative that HM stem bark extract has potential as a therapeutic agent for treatment of subchronic DDVP-induced oxidative stress and its related adverse health conditions. Advance studies are required to elucidate the mechanisms of action of HM stem bark extract and to determine its efficacy in human populations.
Leadership Development through the Study of the Lived Experience

Published: May 2024

Reflection of the lived experience occurs in the solitude of leadership and it is through reflection that educational leaders acquire knowledge. A deep dive into the reflections of the lived experience leads to discernment and it is at this intersect that leadership finds wisdom. The rich data of the lived experience can serve as a valuable resource in leadership development but maximizing the value of the analysis of the lived experience necessitates sharing the findings in a manner that builds capacity in the next generation of leaders. The vehicle used to share the findings is as important as the data we draw from experiences that shape our lives and character.
