This study aims to investigate impact of Mobile Learning Operating Room Principles and Communication Skills on Knowledge, Attitudes, Performance, and Communication Skills of Nursing College Students. In this quasi-experimental study, 60 working students attending a college participated in two groups: the intervention group and the control group. The intervention group received operating room principles and communication skills training through a mobile application, while the control group received conventional classroom-based training on the same subjects. The data collection tools and process included a demographic information form, questionnaires to assess knowledge, attitudes towards mobile learning, communication skills, patient interaction, and checklists for operating room principles and nursing skills of the students in the clinical setting. Pre-tests and post-tests were conducted before and after the intervention to compare the participants' levels of knowledge, attitudes, performance, and communication skills. The data were analyzed using SPSS software version 19, and descriptive and inferential statistics were employed. Before the intervention, there was no statistically significant difference between the knowledge, attitudes, performance, and communication skills of the two groups. However, the statistical tests demonstrated the effectiveness of the interventions. After the intervention, a significant and meaningful difference (P < 0.001) was observed between the two groups' knowledge, attitudes, performance, and communication skills. Based on the results of this study, mobile educational software can assist in the learning and education of students. Since medical students experience most of their learning in clinical settings, attention should be given to developing software and applications in the clinical domain. With the ever-expanding use of mobile devices and the widespread accessibility of these communication tools to almost all students, incorporating mobile-based education can lead to improved medical education in clinical settings.</p>","PeriodicalId":21811,"journal":{"name":"Scientific Reports","volume":"15 1","pages":"27261"},"PeriodicalIF":3.8,"publicationDate":"2025-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144718525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The neural retina leucine zipper (NRL) directs rod photoreceptor differentiation, and its disruption has been linked to upregulated cone-specific markers in rods. This study investigates the therapeutic potential of a cell-penetrating asymmetric small interfering RNA targeting NRL (cp-asiNRL) to induce rod-to-cone conversion and mitigate retinal degeneration. cp-asiNRL was administered intravitreally to C57BL/6J wild-type (WT), neovascular AMD (nAMD), and RP (Rho<sup>P23H/+</sup>) mouse models. Subsequent analyses included cone marker expression levels and electroretinographic evaluations, and single-cell RNA sequencing. Administration of cp-asiNRL suppressed NRL expression, increased cone marker expression, and improved retinal function in both WT and nAMD models. In RP mice, cone marker expression was also elevated, although functional improvements were comparatively modest, likely reflecting the advanced disease stage. Single-cell RNA sequencing revealed a rod-to-cone-like transdifferentiation, suggesting that cp-asiNRL-mediated NRL knockdown partially preserved photoreceptor integrity. cp-asiNRL-mediated NRL silencing shows considerable promise as a therapeutic intervention for retinal degenerative conditions.

In the context of national policies and standards aimed at promoting an increase in the prefabrication rate, recent investigations have revealed that the environmental benefits of prefabricated construction cannot be consistently realized, and the lack of data on the development of prefabricated construction has resulted in limited related research. To address this issue, this paper tackles the issue of inadequate data on indicators pertaining to the growth of prefabricated construction by utilizing crawler technology. It employs the super-efficiency slack-based measure (SBM) model to assess the comprehensive energy-saving and emission-reduction efficiency of China's construction industry. Using the Technology-Organization-Environment (TOE) framework and threshold regression models construct an impact mechanism model to study the main driving factors of energy conservation and emission reduction (ECER) in the construction industry, with a particular focus on the development of prefabricated construction and its associated threshold effects. The results indicate that: (1) China's construction industry's ECER efficiency shows a fluctuating growth trend, with the national average efficiency ranging between 0.6 and 0.8, and significant regional disparities. (2) At this stage, the prefabrication rate, policy effectiveness, and the number of patent applications are key factors affecting the ECER efficiency of the construction industry, with the prefabrication rate and policy effectiveness exhibiting a double-threshold effect. (3) The optimum ECER outcomes are obtained by keeping the prefabrication rate between 50% and 60%, and the effectiveness of policies in fostering these goals is trending downward. Therefore, controlling the rate at which new buildings are prefabricated, comprehending the efficacy of policy standards, and raising the technological level of prefabricated construction are all practical ways to increase the construction industry's efficiency in reducing emissions and conserving energy.

The proposed MWNNs-PSO-NNA shows a very low mean square error and Theil's Inequality Coefficient indicating that the accuracy of the model. To check the convergence and validation of the proposed approach, computing the hundred independent runs for statistical metrics. The fitness function, MSE and TIC values ranging from 10<sup>-07</sup> to 10<sup>-05</sup>, 10<sup>-09</sup> to 10<sup>-07</sup> and 10<sup>-06</sup> to 10<sup>-04</sup> respectively. It is found that increasing the effects of the Williamson number, magnetic parameter, porosity and stretching index inhibit the velocity field while Brownian motion as well as the Williamson number enhances the temperature profile. The concentration rises with Soret and Brownian motion parameters but diminishes with intensified thermophoresis and magnetic influences. These findings confirm that the proposed hybrid model is not only computationally robust but also highly effective for solving complex fluid flow problems in engineering and applied sciences.</p>","PeriodicalId":21811,"journal":{"name":"Scientific Reports","volume":"15 1","pages":"27287"},"PeriodicalIF":3.8,"publicationDate":"2025-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144718602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
