Abstract

The implementation of innovative learning is essential for enhancing the quality of education, particularly in fostering students' critical thinking skills. This study endeavors to assess the effectiveness of the RICOSRE learning model, supplemented by audiovisual media, on students' critical thinking abilities and learning outcomes in the context of circulatory system material. The research methodology employed was quasi-experimental, utilizing a simple random sampling design. The research sample comprised two classes: the experimental class that engaged with the RICOSRE learning model supported by audiovisual media, and the control class that adhered to conventional learning methods. Data were acquired through tests assessing learning outcomes, observation sheets, and student feedback questionnaires. Data analysis was conducted using both descriptive and inferential statistical tests, specifically employing the independent sample t-test. The findings demonstrated a significant difference between the RICOSRE learning model supported by audiovisual media and conventional learning methods regarding critical thinking skills, indicated by a significance value of 0.000, and student learning outcomes, with a significance value of 0.006 at a 5% significance level. This outcome suggests that using the RICOSRE learning model, augmented by audiovisual media, is more effective in enhancing students' critical thinking skills and learning outcomes than traditional methods.

Abstract

Non-healthcare workers in tertiary hospitals in Rivers State face a range of physical hazards, including slips, trips, and falls; eye strain; headaches; fatigue; and more severe injuries like cuts, bruises, fractures, electrical shocks, and body pains, particularly in the neck, shoulders, and back. Therefore, it is crucial to identify, assess, and control these hazards to improve workplace safety, reduce absenteeism, and enhance overall productivity. This study adopted a cross-sectional survey design. A self-structured questionnaire titled "Physical Hazards Questionnaire (PHQ)" with a reliability index of 0.89 was used for data collection. The data were collated, coded, and analyzed using the statistical package of social sciences (SPSS) version 25.0. The study's findings reveal that physical hazards among non-health care workers are a wide range of hazards that can compromise their health and safety. Age, gender, and years of work experience do not significantly influence the physical hazards faced by these workers. Age does not significantly predict physical hazards and gender does not create a significant difference in hazard exposure. The findings can guide interventions aimed at mitigating these hazards.

Abstract

This comprehensive review and meta-analysis examines the efficacy of stem cell therapy in enhancing men’s vitality while supporting national health and defense systems. Patient care records served as the primary source of data for evaluation and analysis, ensuring that real-world clinical outcomes were robustly captured. The study also evaluated the quality assurance of stem cell products cultured by the integrated Celltech Stem Cell Centre Laboratory and Banking, affirming that these products meet stringent clinical standards. Findings indicate that stem cell therapy possesses significant regenerative potential, particularly in repairing damaged cells. Notably, several patients who underwent therapy at the Celltech Stem Cell Center experienced remarkable functional recovery. These results underscore the therapeutic promise of stem cells not only for individual patient recovery but also as a strategic component in enhancing overall public health and national defense readiness.

Abstract

Intellectual property (IP) is a key component of the global economy, and it is also a critical component of ensuring global competitiveness. It is essential for organizations and inventors seeking robust global intellectual property protection to maintain competitive advantage. This study examines the role of structured innovation in enhancing patent approval rates, mitigating legal risks, and accelerating market entry for technological innovations. The study employs a mixed-methods approach, integrating legal analysis, case study evaluations, empirical data collection, and AI-based predictive modeling to provide an in-depth understanding of the factors contributing to successful patent filings and long-term intellectual property sustainability. The research also examines emerging trends in artificial intelligence and predictive analytics that are reshaping the landscape of IP management. The findings derived from this study serve as a valuable resource for policymakers, legal practitioners, and industry stakeholders seeking to enhance their innovation strategies in an increasingly competitive and complex intellectual property landscape. Specifically, this study aims to provide a strategic roadmap for optimizing patent filing and securing global protection by evaluating real-world applications and examining cross-jurisdictional intellectual property frameworks. A comparative study of patent laws across key jurisdictions, including the United States, the European Union, and China, highlights critical differences in examination procedures, enforceability, and litigation risks, providing comparative insights essential for businesses operating in global markets. The empirical findings underscore that structured innovation methodologies contribute to higher patent success rates and reduce legal uncertainties, enforcement complexities, and post-grant challenges.

Abstract

This study aims to develop a more effective and data-based strategy for the management of ex-termination materials in the upstream oil and gas industry, integrating ABC, VED, and FMSD methods with Analytical Hierarchy Process (AHP). The analysis was carried out by integrating the ABC-FMSD-VED matrix approach. The results showed that 21% of category A materials accounted for 80% of the total inventory value, while 85.95% of materials were included in the Deadstock category, which was not optimally utilized. The AHP analysis showed that the top priority was internal utilization, followed by borrowing, transfer, and deletion, with sensitivity tests indicating decision stability.

Abstract

Postoperative pain, a significant surgical complication, presents a considerable challenge to the healthcare system, resulting in adverse outcomes, disability, prolonged hospitalization, and financial strain. This study seeks to evaluate the effectiveness of liposomal bupivacaine (LB) in postoperative pain management by a systematic review and meta-analysis of existing research. PubMed, CENTRAL, Embase, Web of Science, and Google Scholar were searched for randomized controlled trials (RCTs) published until January 2025, focusing on adults (18 years) undergoing surgical procedures where LB was administered via wound infiltration, nerve blocks, or periarticular injections. Primary outcomes included pain scores (VAS/NRS/BPI), opioid consumption, adverse events (e.g., nausea/vomiting), and patient satisfaction. A total of 763 papers were discovered in the literature, of which 21 (Barrington et al., 2017) were included. The pooled standardized mean difference (SMD) was -0.53, (95% CI, [-0.84, -0.23]; p = 0.0006) signifying a statistically significant decrease in pain levels favoring the intervention group. No significant disparity in opioid use was found between the two groups. The combined odds ratio (OR) was 0.78 (95% confidence interval (CI): [0.46 to 1.31]; [p = 0.35), indicating no significant difference in the incidence of nausea and vomiting. LB is effective in alleviating pain, diminishing opiate usage, and alleviating postoperative side effects.
