Algorithmic Explosion or Emotional Resonance? An Analysis of the Cross-Regional Dissemination Mechanism of the Song Méi chūxī and Emotional Identification Among People in the Chinese Mainland and Taiwan Region
Full text linkIntroduction: digital technology and social media boost cross-regional popular culture dissemination. The song Méi Chūxī spreads across Chinese Mainland and Taiwan Region via algorithms and emotional resonance, yet its dissemination mechanism remains understudied.Objective: to explore the core drivers, differential paths of Méi Chūxī’s cross-regional dissemination, and its interactive logic with audiences’ emotional identification.Method: grounded theory was adopted, combining in-depth interviews with 25 respondents (13 from Mainland, 12 from Taiwan) and online dissemination data analysis.Results: dissemination is driven by algorithm fission and dissemination motivation synergy; emotional resonance mediates contact, cognition, and dissemination. Regional background moderates paths—Mainland relies on algorithm-driven rapid spread, Taiwan on social circle diffusion.Conclusions: this study constructs a dissemination-identification interaction model, filling research gaps and providing references for cross-strait cultural communication
Sikuadrat: Mathematics learning media with the Merdeka flow in solving quadratic equations and functions
Full text linkThe use of smartphones in education, particularly in mathematics learning for high school students, is becoming more prevalent as most students are familiar with Android-based devices. However, despite widespread access to smartphones, not all students utilize them as learning tools, and there remains a lack of engaging and interactive learning media tailored for this platform. This study aimed to develop and assess the effectiveness of "Sikuadrat," a mobile-based learning media focused on quadratic functions and equations. The media employs the MERDEKA instructional flow, designed to facilitate student engagement and understanding in solving quadratic equations. The development process followed the ADDIE (Analysis, Design, Development, Implementation, Evaluation) model. Data collection involved observations, interviews, documentation, and questionnaires, conducted with high school students and mathematics teachers at SMA 1 Klaten, Indonesia. The media\u27s practicality and effectiveness were evaluated based on feedback from the participants. Results show that Sikuadrat is a highly valid and practical tool for enhancing the learning experience in mathematics, particularly for topics related to quadratic functions and equations. The media not only supports interactive problem-solving but also aligns with the instructional goals of mathematics education in high schools. In conclusion, Sikuadrat offers a valuable solution for integrating technology into mathematics learning and is suitable for implementation in high school curricula to support students’ mastery of quadratic functions and equations, making it an effective and accessible learning tool for smartphone user
Computerized anesthesia versus conventional anesthesia on self-perceived pain in children: systematic review and meta-Analysis
Full text linkIntroduction: local anesthesia and computerized anesthesia via infiltrative technique have become a key component for painless dental treatments. This study aimed to evaluate the efficacy of computerized anesthesia compared to local anesthesia applied through the infiltrative method. Method: an electronic search for randomized clinical trials published between 2019 and 2024 was conducted in the Medline, Scopus, and Virtual Health Library databases. The search strategy used was \u27Computerized anesthesia OR local anesthesia AND pain AND pediatrics.\u27 A total of 170 articles were found, of which eight randomized clinical trials were analyzed in a qualitative synthesis, and six in a subsequent meta-analysis. Results: the results indicated that computerized anesthesia compared to local anesthesia is more effective in reducing self-perceived pain, presenting a large effect size (SMD: -1,05; 95% CI: -2,01 to -0,08). However, the few studies analyzed together with the high heterogeneity (Tau2= 1.38; Chi2= 120,76, df = 5, p < 0,001; I2 = 96 %) do not allow a complete affirmation of these findings despite that the literature has suggested better acceptance and reduction of fear of dental procedures associated with the use of syringes in the pediatric population. Conclusion: it is suggested that computerized anesthesia is more effective in reducing pain, although it is more expensive and requires more training to achieve an optimal, painless procedure that can reduce phobias associated with dental treatments
Knowledge, Perceptions and Practices of Midwives in the Prevention of Pressure Injuries in Neonatal Critical Care Units
Full text linkIntroduction: pressure injuries (PI) in critically ill neonates are a health problem with a negative impact on morbidity, mortality, and healthcare costs. Knowledge and management of PI prevention by healthcare professionals are crucial for improving clinical practice. Objective: to analyze the level of knowledge, perceptions, and practices of midwives in Neonatal Critical Care Units (NCCU) regarding PI prevention. Material and Methods: a quantitative, descriptive, non-experimental, cross-sectional study with a sample of 32 midwives from three NCCUs in the Fifth Region of Chile. The validated PREVINTLPP questionnaire was used. Results: knowledge of PI prevention was insufficient (average 64,8 % minimum 70 % to be considered adequate), with great variability in responses. Adherence to recommended clinical practice was even lower (43,5 % on average). There is awareness that PIs are a quality indicator, but 96,9 % are unaware of international guidelines for their management. Conclusions: Knowledge of PI prevention in the study sample is inadequate, possibly due to poor knowledge management. Further investigation into the causes and implementation of specialized training programs are needed to improve the quality of care and patient safety
Building Bright Minds: A Comprehensive Study on Developmentally Appropriate Practices for Enhancing Elementary Students\u27 Mental Health
Full text linkIntroduction: Quality learning is essential to achieve national education goals. However, current practices often neglect students’ mental health needs, and focus more on academic achievement.Objective: The purpose of this study was to analyze the need to develop a Developmentally Appropriate Practices (DAP) learning model that specifically targets the mental health of elementary school students.Method: This study used a qualitative case study design approach, involving 30 teachers and 3 mental health professionals from Surakarta city. Data were collected through in-depth interviews with educators and mental health professionals, as well as classroom observations. Data were analyzed thematically to identify relevant patterns and themes related to the development of the DAP learning model. Interview guides and observation sheets were used as research instruments.Results: The findings revealed three main problems: 1) lack of attention to mental health aspects in the curriculum and learning practices, with an exclusive focus on academic performance; 2) lack of trained personnel to address mental health needs in schools; and 3) students face challenges in adapting to academic and social demands, which can lead to stress and mental health problems. The DAP learning model can improve the mental health of elementary school students by integrating emotional, social, and academic aspects, thereby fostering a supportive environment that increases students\u27 sense of connectedness and confidence in learning.Conclusion: The development of the Developmentally Appropriate Practices (DAP) learning model is essential to address the mental health needs of elementary school students. By incorporating emotional and social dimensions into educational practice
The Role of HCN4 Variants in Human Systolic Heart Failure and Protein Interaction Network
Full text linkIntroduction: An elevated heart rate (HR) results in adverse outcomes in human systolic heart failure with a sinus rhythm. Genetic variants may alter HCN4 interactions with regulatory proteins and increase HR. This study aimed to generate a protein interaction network (PIN) associated with elevated HR and to determine HCN4 gene variants (718G>A, 1571G>A, and 2648C>G) in patients with systolic heart failure, sinus rhythm, and elevated heart. Methods: STRING protein database was used to generate a PIN. Laboratory exploration was performed to identify HCN4 gene variants in patients with systolic heart failure using PCR and DNA sequencing. Results: PIN revealed eight nodes and 13 edges. STRING functional enrichment showed the essential proteins (ADRB1 and HCN channels) involved in HR regulation. GNAS and ADCY1 contributed to the regulation process. HCN4 gene variants (718G>A, 1571G>A, and 2648C>G) alter the properties of HCN4 channel. STRING scores of protein-protein interactions that involved HCN4, ADRB1, GNAS, and ADCY1 were high (in the range of 0.879-0.979). The three gene variants were evaluated in 49 study participants with HR≥70 bpm after 10 mg bisoprolol therapy. However, only 718G>A was identified in three of 49 patients. Conclusion: PIN revealed that the three essential proteins associated with HCN4 channels in elevating HR were ADRB1, GNAS, and ADCY1. Only HCN4 718G>A was found in three out of 49 patients with systolic heart failure, sinus rhythm, and increased HR, according to a laboratory investigation on HCN4 gene variant
Early-Stadium Chronic Kidney Disease Patients Experiences of Self Management on A Cultural perspective: A Qualitative Study
Full text linkBackground : Self-management is the gold standard of care for early CKD patients which is useful for preventing complications and slowing down the decline in kidney function. The experience of early CKD patients in carrying out self-management is very important to improve the ability, independence and right decision making in carrying out self-management. This study aimed to explore the self-management experience in adults diagnosed early chronic kidney disease in culture perspective of Javanes.Methods : This study is a qualitative with a phenomenological approach, using semi-structured in-depth interviews with 27 adult patients diagnosed with early stage 1-3 chronic kidney disease. Data were analyzed using thematic analysis with the Colaizzi analysis method.Results : The results of the analysis reveal the experiences of early chronic kidney disease patients with self-management, consist of 4 main themes: 1) family support in self-management, 2) Care decision making with family, 3) unhealty eating habit, and 4) using traditional medicine in kidney health maintenance. Conclusion : The results of the study concluded that the Javanese culture that is in line with self-management in early chronic kidney disease patients is family relationships and traditional medicine. Family relationships in Javanese culture has high philosophical values and supports health care. Traditional medicine is also still the choice of early chronic kidney disease patients with Javanese ethnicity in carrying out self-management. This study recommends the need for nursing interventions that are tailored to the patient\u27s culture by integrating family care practices and traditional medicine to improve self-management in early chronic kidney disease patients
Developing a Framework for Electoral Education Among Students with a Focus on Vulnerability
Full text linkThe Undi18 bill, lowering the voting age from 21 to 18, marked a significant step in Malaysia\u27s democratic evolution. However, the political maturity of young voters and their vulnerability to external pressures remain major concerns. This study explores university students\u27 perceptions of general elections, their views on the Undi18 legislation, and their political awareness in the lead-up to Malaysia’s 15th general election. Through a mixed-methods approach—combining quantitative surveys with qualitative interviews—this research highlights the need for a structured electoral education framework to mitigate the vulnerabilities of young voters. Findings suggest that while most students show strong awareness and engagement, many are still vulnerable to political influences and societal expectations. This study proposes educational strategies to bolster political literacy and protect student voters from manipulatio
Effectiveness of the use of voice amplification systems in the educational field: A systematic review
Full text linkIntroduction: teachers face high vocal demands, increasing the risk of developing voice disorders due to overexertion. This study reviews the use of voice amplification systems and their effect on educators\u27 vocal health.Methods: a systematic literature review was conducted with articles published between 2013 and 2024 in Spanish, English, or Portuguese in the Scopus, PubMed, and EBSCO databases using the PRISMA methodology.Results: studies show that portable voice amplifiers can reduce vocal intensity and fundamental frequency, minimizing vocal load and improving speech clarity in educational settings. However, this would only be effective in the presence of a previous vocal pathology.Conclusions: the use of voice amplification systems could be advantageous for teachers with previous vocal problems, especially women, although more research is required to determine their long-term safety and prevent potential vocal damage. It is recommended to combine amplification with other preventive measures such as acoustic improvements and voice care programs for comprehensive management of teachers\u27 vocal health
Assessment of the nutritional status of institutionalized older adults in two residences
