MATHEMATICAL FOUNDATIONS OF MODELING TRUST COMPUTATION IN COMPLEX NETWORKS

Dinh Que Tran — 2025-03-31

Modeling trust computation in complex networks has become increas
ingly important in various domains, including social networks, telecom
munication networks, multi-agent systems, transportation and distributed
computing. This paper introduces a novel approach to modeling trust
based on two primary metrics: belief and trustworthiness. We explore
the theoretical foundations, computational methods of these metrics with
a functional approach and deep learning in modeling trust in complex
networks.

NURSING STUDENT ATTITUDES AND BARRIERS TOWARD RESEARCH IN THE CONTEXT OF EDUCATION: A CROSS-SECTIONAL STUDY IN HO CHI MINH CITY

Nguyen Duy Phong — 2025-03-31

Nurses’ attitudes toward research have been extensively studied, but limited data exists on the attitudes and barriers faced by nursing students. Understanding these factors is crucial, as positive attitudes toward research can inspire students to engage in research activities, enhance their skills, and apply evidence-based findings in clinical practice to improve patient outcomes.This study aimed to explore the attitudes, barriers, and influencing factors related to research among nursing students at Nguyen Tat Thanh University, Ho Chi Minh City. A crosssectional study involving 520 nursing students was conducted between December 2023 and September 2024. Data were collected through a self-administered questionnaire, incorporating the Attitudes Toward Research (ATR) scale and a barriers-to-research scale. Statistical analyses included Chi-square/Fisher’s exact tests and logistic regression.The study found that 63.7% of nursing students exhibited a positive attitude toward research, while 36.3% displayed poor attitudes. The overall mean attitude score was 4.74 ± 0.87. Students with B and C grades in research courses had significantly better attitudes toward research, with odds ratios of 2.54 (95% CI: 1.30-4.96) and 2.68 (95% CI: 1.07-2.54), respectively. The primary barriers identified were personal reasons (mean = 3.65± 0.68), lack of university policy support (mean = 3.37± 0.81), and insufficient mentorship and curriculum support (mean = 3.17 ± 0.75). Most nursing students demonstrated positive attitudes toward research, though significant barriers remain. Universities should foster a researchpositive culture by encouraging student participation in research activities, enhancing mentorship, and making a bachelor’s thesis a graduation requirement. These initiatives can empower future nurses to embrace evidence-based practice and contribute meaningfully to patient care.

EFFICACY OF NURSE-LED REHABILITATION PROGRAM IN IMPROVING OUTCOMES FOR CHRONIC OBSTRUCTIVE PULMONARY DESEASE (COPD) PATIENTS

Nguyen Thi Phuong Uyen — 2025-03-31

This study evaluates the effectiveness of nurse-led rehabilitation programs in enhancing the quality of life for patients with Chronic Obstructive Pulmonary Disease (COPD) and explores their impact on hospital readmission rates and patient satisfaction compared to traditional rehabilitation settings. Utilizing a randomized controlled trial design, this research surveyed 100 COPD patients over three distinct periods: before treatment, and at 7 and 14 days post-treatment initiation. The primary objective focused on quantifying improvements in the patients’ quality of life, employing both quantitative and qualitative measures. Secondary objectives included an analysis of the reduction in hospital readmissions and an assessment of patient satisfaction in nurse-led versus traditional settings. Initial findings suggest that nurse-led programs significantly improve quality of life and reduce hospital readmissions while enhancing patient satisfaction due to their holistic and patient-centered approach. The study’s implications highlight the potential for nurse-led interventions to optimize COPD management and suggest a shift towards more personalized healthcare frameworks in chronic disease management.

GENETIC ANLYSIS OF SEVEN GARLIC VARIETIES FROM PROMINENT GROWING AREAS IN SOUTHERN VIETNAM

Pham Van Hien — 2025-03-31

This study aimed to assess the genetic similarity and diversity of seven garlic accessions from Vietnam using Simple Sequence Repeat (SSR) markers. Whole garlic bulbs were used for DNA extraction, which was performed using the GeneJET Plant Genomic DNA Purification Kit. DNA concentration and purity were determined using a NanoVue Plus spectrometer. PCR procedures for each primer set were optimized, and the best amplification temperature regime was selected. Of the ten SSR primer sets used, Asa04, Asa06, Asa07, Asa08, Asa16, Asa18, and Asa20 showed good amplifications with bright, clear bands. In contrast, Asa10 and Asa14 did not amplify the DNA of any samples, and Asa17 did not amplify the DNA from the NhonHai, VanHai, and NinhHoa samples but did for the other samples. The genetic distance matrix revealed high similarity among the garlic samples, ranging from 0.90 to 1.00. The phylogenetic analysis grouped the samples into two clusters: Group I (VinhHai1, VinhHai2, VinhHai3, and LySon) and Group II (NhonHai, VanHai, and NinhHoa), suggesting that the samples within each group likely originated from the same source. These findings highlight the necessity of using more molecular markers and conducting in-depth biochemical analyses to further understand the genetic and biochemical differences between garlic varieties in Vietnam. This study provides a foundation for future research on garlic breeding and cultivar improvement.

THE IMPACT OF TAMANU OIL (Calophyllum inophyllum L.) ON IMPROVING THE WOUND HEALING PROCESS IN DIABETIC MICE MODEL

Phan Duy An — 2025-03-31

Diabetic ulcers pose a significant challenge in clinical practice due to impaired wound healing caused by hyperglycemia, infections, and oxidative stress. This study evaluates the effects of Tamanu oil (Calophyllum inophyllum L.) from Hue City on wound healing in a diabetic mouse model. Chemical analysis revealed that Tamanu oil contains bioactive compounds, including calophyllolid and hexadecanoic acid, with antioxidant, anti-inflammatory, and antibacterial properties. In vitro experiments demonstrated that Tamanu oil stimulates fibroblast proliferation and exhibits antibacterial activity. In vivo studies on diabetic mice showed faster wound closure and earlier hair regrowth compared to the control group, suggesting that Tamanu oil supports diabetic wound healing.
