Authors: Gebeyehu Elsabet 
Published: January 2025

Abstract

The purpose of this study was to examine the effect of principals’ adaptive leadership practice on teachers’ work engagement in secondary schools of central Gondar zone. Explanatory sequential mixed design was employed. The size of the study population was 995. Of these, 283 teachers were selected by using simple random sampling technique while 4 school principals and 2 supervisors were purposely selected. Questionnaire and interview were used to collect the data. The data were analyzed both quantitatively and qualitatively. The result of one sample t-test and interview indicated that adaptive leadership practice and teacher work engagement were observed to some extent in the workplace. There was a statistically significant moderate relationship between adaptive leadership practice and teacher work engagement. The result of multiple regression indicated that 34.2% of the variance in work engagement was significantly predicted by the six dimensions of adaptive leadership. The result of two-way ANOVA indicated that a significant difference was not found among teachers in their perception of work engagement based on gender, educational qualification, and work experience. Resistance to change, lack of trust and collaboration among teachers and principals, lack of trained principals in leadership positions, and lack of human and financial resources were found the major challenges hindered the implementation of adaptive leadership. Therefore, it is concluded that adaptive leadership has a significant effect on work engagement. Thus, training programs need to be developed to improve the status of adaptive leadership and teachers' work engagement in the study area.

Abstract

Green asparagus is a labor-intensive vegetable crop for harvesting. Rising labor costs and seasonal labor shortages are threatening the sustainability and profitability of the asparagus industry in the United States (U.S.), making harvesting automation more urgently needed than ever. A multitude of challenges, however, exist in developing practically variable automated harvesting technology for green asparagus. This study describes a novel effort aimed at the development and evaluation of a 3D vision-based asparagus perception system for selective harvesting of U.S. green asparagus. Three different types of 3D cameras were evaluated indoors for asparagus detection and length estimation. A time-of-flight technology-based camera yielded the best accuracy and was deployed on a mobile vision system for imaging asparagus in diverse field conditions. A new annotated dataset alongside ground-truth length measurements for 1008 spears was created for asparagus perception algorithm development and evaluation. Among three small-scale YOLO (v8, v9, and v10) models, YOLOv8s achieved the best F1 score of 0.849. The YOLOv8s-based pipeline point cloud processing algorithms including segmentation, clustering, and outlier removal, achieved a percentage accuracy of 89.4% (with the corresponding error of about 2.3 cm) in spear length estimation, and the averaged base point localization error of 1.4 cm. The entire algorithm pipeline for spear detection and localization could be run at about 3.3 frames per second on an onboard computer. The harvest eligibility analysis of detected spears showed a detection rate of 95.8% of harvestable spears when only the length criterion (greater than 8 inches or 20.3 cm) was applied and a detection rate of 84.5% when both the length and base point localization (error less than 2 cm) criteria were considered. The 3D vision-based perception system in this study is promising for reliable and real-time asparagus perception in production fields.

The non-specific symptoms of impaired tolerance to enteral feeding and the lack of laboratory and instrumental methods for early detection of changes in intestinal permeability make timely assessment of the intestinal barrier in newborns a complex clinical challenge. Identifying reliable and specific markers that differentiate between functional gastrointestinal disorders and early stages of surgical pathology in newborns is an area of significant interest for a wide range of specialists.Purpose. The study aimed to evaluate the impact of gestational age on the serum levels of Claudin-2, a tight junction protein in enterocytes, in infants during the first months of life.Material and methods. The study included 115 newborns with gestational ages (GA) ranging from 33 to 41 weeks (median GA 38.0 [36.0–39.0] weeks). The infants were divided into two groups based on GA: Group 1 (term infants, median GA 39.0 [38.0–40.0] weeks, n=80) and Group 2 (preterm infants, median GA 35.0 [34.5–36.0] weeks, n=35). Serum Claudin-2 levels were measured during the first months of life using a Human CLDN2 enzyme immunoassay kit. Results. Serum Claudin-2 concentrations increased from 3.434 [1.198; 7.866] ng/ml in the first 10 days of life to 5.147 [3.529; 8.211] ng/ml (p=0.02) by 1–1.5 months, with the most pronounced increase observed in term infants (from 1.508 [1.004; 4.33] ng ml to 4.302 [3.188; 5.776] ng/ml, p<0.001). An inverse correlation was noted between GA and Claudin-2 concentration in the first days of life (–0.507, p<0.001), which weakened by 1–1.5 months (–0.342, p<0.001). Additionally, higher Claudin-2 concentrations were observed in preterm infants at a postmenstrual age of 40–41 weeks compared to full-term infants at birth (p<0.001).Conclusion. The findings demonstrate the influence of GA on Claudin-2 levels in the first months of life, suggesting increased intestinal permeability in infants with lower gestational maturity, mediated by variable Claudin-2 expression.

Effects of adopting IFRS 9 for the audit of financial instruments in non-financial companies
Authors: Silva Shirley Franco da , Dantas José Alves 
Published: January 2025

Objective: The aim of this study is to determine the effects of adopting IFRS 9 for the auditing of financial instruments in non-financial companies in Brazil.
Methodology: The empirical tests were based on the data obtained from 338 non-financial companies listed in the B3 (Stock Exchange) in the period from 2014 to 2021, that appeared in the financial statements and auditing reports on the CVM website. The statistical tests were conducted in two stages: i) a descriptive analysis, through a comparison of the number of references to financial instruments, including the reasons for any alteration of opinion in the pre- and post- IFRS 9 periods; and ii) hypothesis testing of research by means of logistic regression estimates.
Results: The results of the empirical tests revealed that the adoption of IFRS 9 is positively related to the references to financial instruments in the auditing reports, although they have not led to a rise in the number of altered opinions.
Contributions made by the study: The empirical evidence arising from the literature on the auditing of financial instruments makes it possible to determine how the introduction of new accounting standards has affected the process of auditing and enabled the regulators and users of the information to understand the possible outcomes of regulations on the audit procedures for financial instruments. In addition, the findings made clear what factors determine how the adoption of IFRS 9 has affected the audit reports and the work they involve. They fill a gap in the literature with regard to the direct bearing IFRS 9 has on non-financial entities, given the fact that previous studies have concentrated on other aspects of the auditing of financial instruments and almost always been concerned with financial institutions.

Authors: Briggs Blake , Mulekar Madhuri , Morales Hannah , Husain Iltifat 
Published: January 2025

Abstract

Background
The COVID-19 pandemic challenged medical educators due to social distancing. Podcasts and asynchronous learning platforms help distill medical education in a socially distanced environment. Medical educators interested in providing asynchronous teaching should know how these methods performed during the pandemic.

Objective
The purpose of this study was to assess the level of engagement for an emergency medicine (EM) board review podcast and website platform, before and during the COVID-19 pandemic. We measured engagement via website traffic, including such metrics as visits, bounce rate, unique visitors, and page views. We also evaluated podcast analytics, which included total listeners, engaged listeners, and number of plays.

Methods
Content was designed after the American Board of EM Model, covering only 1 review question per episode. Website traffic and podcast analytics were studied monthly from 2 time periods of 20 months each, before the pandemic (July 11, 2018, to February 31, 2020) and during the pandemic (May 1, 2020, to December 31, 2021). March and April 2020 data were omitted from the analysis due to variations in closure at various domestic and international locations. Results underwent statistical analysis in March 2022.

Results
A total of 132 podcast episodes and 93 handouts were released from July 11, 2018, to December 31, 2021. The mean number of listeners per podcast increased significantly from 2.11 (SD 1.19) to 3.77 (SD 0.76; t test, P<.001), the mean number engaged per podcast increased from 1.72 (SD 1.00) to 3.09 (SD 0.62; t test, P<.001), and the mean number of plays per podcast increased from 42.54 (SD 40.66) to 69.23 (SD 17.54; t test, P=.012). Similarly, the mean number of visits per posting increased from 5.85 (SD 3.28) to 15.39 (SD 3.06; t test, P<.001), the mean number of unique visitors per posting increased from 3.74 (SD 1.83) to 10.41 (SD 2.33; t test, P<.001), and the mean number of page views per posting increased from 17.13 (SD 10.63) to 33.32 (SD 7.01; t test, P<.001). Note that, all measures showed a decrease from November 2021 to December 2021.

Conclusions
During the COVID-19 pandemic, there was an increased engagement for our EM board review podcast and website platform over a long-term period, specifically through website visitors and the number of podcast plays. Medical educators should be aware of the increasing usage of web-based education tools, and that asynchronous learning is favorably viewed by learners. Limitations include the inability to view Spotify (Spotify Technology S.A.) analytics during the study period, and confounding factors like increased popularity of social media inadvertently promoting the podcast.
Reviewing Mobile Apps for Teaching Human Anatomy: Search and Quality Evaluation Study
Authors: Rivera García Guadalupe Esmeralda , Cervantes  López Miriam Janet , Ramírez Vázquez Juan Carlos , Llanes Castillo Arturo , Cruz Casados Jaime 
Published: January 2025

Background
Mobile apps designed for teaching human anatomy offer a flexible, interactive, and personalized learning platform, enriching the educational experience for both students and health care professionals.

Objective
This study aimed to conduct a systematic review of the human anatomy mobile apps available on Google Play, evaluate their quality, highlight the highest scoring apps, and determine the relationship between objective quality ratings and subjective star ratings.

Methods
The Mobile App Rating Scale (MARS) was used to evaluate the apps. The intraclass correlation coefficient was calculated using a consistency-type 2-factor random model to measure the reliability of the evaluations made by the experts. In addition, Pearson correlations were used to analyze the relationship between MARS quality scores and subjective evaluations of MARS quality item 23.

Results
The mobile apps with the highest overall quality scores according to the MARS (ie, sections A, B, C, and D) were Organos internos 3D (anatomía) (version 4.34), Sistema óseo en 3D (Anatomía) (version 4.32), and VOKA Anatomy Pro (version 4.29). To measure the reliability of the MARS quality evaluations (sections A, B, C, and D), the intraclass correlation coefficient was used, and the result was “excellent.” Finally, Pearson correlation results revealed a significant relationship (r=0.989; P<.001) between the quality assessments conducted by health care professionals and the subjective evaluations of item 23.

Conclusions
The average evaluation results of the selected apps indicated a “good” level of quality, and those with the highest ratings could be recommended. However, the lack of scientific backing for these technological tools is evident. It is crucial that research centers and higher education institutions commit to the active development of new mobile health apps, ensuring their accessibility and validation for the general public.

Authors: Nurrokhmanti Hikmawati , Arif Luthfi Saiful , Sari Silvia Mustika , Widyandana Widyandana , Claramita Mora 
Published: January 2025

Background: Publications in the medical education field need more attention. It was shown by the MERSQI data score that there is no significant difference between medical education publications in the US (Society of General Internal Medicine, 44,4%) and Turkish (Turkish National Medical Education Congresses and Symposia, 11,3%) in 2014/2015. Therefore, specific strategies should be implemented to raise the quality and quantity of publications in the medical education area. With this recommendation, the number of publications in the medical education area is expected to increase.Gaps: In a study on the quality of publication in Turkish National Medical Education Congresses and Symposia, there is a significant difference in MERSQI score between unpublished (oral/poster presentation) and published papers.1 It is indicated that the quality of scientific papers needs to be increased. While in Indonesia, no further study is related to the quantity and quality of published papers. It is assumed that publication problems in the medical education field stem from the quality of scientific papers and could relate to Indonesian scholars' false publication strategy. Recommendation: The quality of scientific publications in Indonesia needs an improvement strategy that should be implemented in every scientific institution in Indonesia, starting from the master's degree level. The increasing proportion of research and any supporting material is expected to increase publication with high-quality research. The following recommendation is about the strategy of publishing the paper, which begins with selecting the fit or right scientific journal, followed by increasing scholar adherence to the journal's requirements.
