Solar-powered multi-scale sensor node on Imote2 platform for hybrid SHM in cable-stayed bridge
No full textIn this paper, solar-powered, multi-scale, vibration-impedance sensor node on Imote2 platform is presented for hybrid structural health monitoring (SHM) in cable-stayed bridge. In order to achieve the objective, the following approaches are proposed. Firstly, vibration- and impedance-based hybrid SHM methods are briefly described. Secondly, the multi-scale vibration and impedance sensor node on Imote2-platform is presented on the design of hardware components and embedded software for vibration- and impedance-based SHM. In this approach, a solar-powered energy harvesting is implemented for autonomous operation of the smart sensor nodes. Finally, the feasibility and practicality of the smart sensor-based SHM system is evaluated on a full-scale cable-stayed bridge, Hwamyung Bridge in Korea. Successful level of wireless communication and solar-power supply for smart sensor nodes are verified. Also, vibration and impedance responses measured from the target bridge which experiences various weather conditions are examined for the robust long-term monitoring capability of the smart sensor system
The Health-Seeking Behavior of the Elderly with Non-communicable Diseases at Coastal areas, Vietnam
Get PDFBackground The aging population is rapidly increasing globally. It proves a severe impact on developing and low-income countries due to insufficient resources and lack of awareness towards the challenges of health issues. In Vietnam, over 11 million people aged 60 and over, accounting for 11.8% of the population. It is projected that by 2050 there will be nearly 29 million people (HelpAge, 2018). People over 60 years old have 2.6 diseases, over 80 years old have 6.8 diseases on average (Dang Thi Thanh et al., 2018; MOH, 2020). Therefore, healthcare facilities and the health services behavior of older populations with non-communicable diseases are considered important in formulating a health program targeting this group. Significantly, the coastal area is a challenging area where participants live (Government, 2016b). Purpose This study aimed to investigate the health-seeking behavior of the elderly with non-communicable diseases, and its associated factors. Method A Cross-sectional study was conducted in seven coastal areas in Thua Thien Hue province, Vietnam, with a sample of 370 people aged 60 years and older. Physicians diagnosed the presence of non-communicable diseases at health care facilities. Information on independent variables such as social, demographic, perceived health status, etc., and dependent variables such as health-seeking behavior through the utilization of healthcare services were collected using a structured questionnaire. In addition, a pilot investigation questionnaire on patients who visit a primary healthcare unit in one of seven coastal areas was conducted, and investigators were trained before collecting data. Chi-square and multiple logistic regression analyses were used to examine the factors associated with the utilization of health care services. Results The mean age of participants was 69.70 ± 6.6 (SD). Over half of the participants were fishery or agriculture, 14.3% of them were under an average standard of economic. The proportion of multiple non-communicable diseases was 18%. The disease duration was mainly about 5-10 years and more than ten years with the rate over 40%, respectively. Most participants were diagnosed at public health facilities. A third of quarter of participants required health care counseling. The results of the study showed that 69.8% of the total participants had health-seeking behavior. The findings also revealed that the elderly living alone were likely to have 4.5 times less health-seeking behavior than those who did not live alone (OR: 4.48, 95% CI: 1.016-19.78, p=0.048). Similarly, the economic status was related to the health-seeking behavior. People with an average and wealthier income seemed to have 2.8 times higher utilization of healthcare services than the poor and below the average group (OR: 2.81, 95% CI: 1.11-7.11, p=0.029). A group with multiple NCDs were more likely to have nine times higher health-seeking behavior than those with only one disease (OR: 9.24, 95% CI: 2.665-32.15, p=<0.001). Health insurance and the needed for health care counseling were also relevant (OR: 4.16, 95% CI: 1.30-13.31, p=0.016), (OR: 3.91, 95% CI: 2.04-7.49, p<0.001), respectively. Conclusion Health-seeking behavior is one of the most important positive implications for the aged population, encompassing one's physical, mental, and psychological wellbeing. The future study would be clarifying the same results in-depth to understand and improve the health-seeking behavior in the elderly and enhance their quality of life.open석

All patients underwent preoperative 3 Tesla magnetic resonance imaging examinations with conventional and DTI sequences. Data on preoperative imaging and pre- and postoperative clinical characteristics of patients were retrospectively collected. Univariate and multivariate linear regressions were applied to analyze the relationships between preoperative parameters and pre- and postoperative muscle strength and the Karnofsky Performance Status (KPS) score.Results: Fourteen patients had low-grade gliomas and 29 had high-grade gliomas. Although the corticospinal tract (CST) score did not differ significantly between tumor grades, edema and deviation were common in low-grade gliomas (64.3%), while destroyed and infiltrated lesions were common in high-grade gliomas (58.6%). Muscle strength improved after surgery in the deviated tract group (40%) more than in the infiltrated tract group (33.3%). Two independent indices, preoperative muscle strength (p = 0.000) and glioma-to-CST distance (p = 0.001), were linearly related to postoperative muscle strength. The preoperative KPS score was the only indicator that affected the postoperative KPS score (p = 0.000).Conclusion: DTI should be considered in surgical management of supratentorial gliomas in the motor function area to determine the appropriate surgical strategy and predict the nature of the tumor and postoperative motor function.Keywords: diffusion tensor imaging, supratentorial glioma, preoperative planning, surgical outcomes, motor corte

Building a brand name for universities: A case study of Ho Chi Minh City Open University
Get PDFIn the era of globalization and internationalization, students have many choices when pursuing their educational paths. Students today are more mobile and willing to leave their homes to study at their desired university. Building a brand name in this increasingly competitive landscape can be the primary tool for higher education institutions, particularly universities, to differentiate themselves and gain a competitive advantage. However, research on university branding is scarce, and the concept of university branding remains largely unexplored in the Vietnamese context. This study explores how a university can use banding strategies to build its brand name. The analysis utilizes an organizational perspective to gather valuable information and insights into a university’s activities to build and enhance its brand name. Ho Chi Minh City Open University (OU), a top-tiered public university with its main campuses and learning precincts in Ho Chi Minh City, Vietnam, is selected to conduct this study. The nature of the study is qualitative, and data is collected through in-depth semi-structured interviews with current leaders and staff at the University. The sample utilized in this study includes staff from various departments within the university and current and former executives to gain a comprehensive understanding and capture diverse perspectives. The key findings can be summarized as follows. First, primary stakeholders such as students, parents, staff, and others targeted by the University require different branding strategies. Second, OU can build its brand name through its students and alumni who have studied at the university. Third, OU needs a comprehensive strategy concerning brand name-building and enhancing activities with a focus on students’ affairs and communication. Recommendations have emerged based on these findings for building and enhancing the brand name of Ho Chi Minh City Open University, Vietnam
