An Immersive Digital Twin Applied to a Manufacturing Execution System for the Monitoring and Control of Industry 4.0 Processes

The present research proposes the implementation of an architecture for industrial process monitoring and control for a manufacturing execution system (MES) using an immersive digital twin (DT). For the design of the proposal, cyber–physical systems (CPS), MES, robotics, the Internet of Things, augmented reality, virtual reality, and open platform communication-unified architecture (OPC UA) communication protocols were used to integrate these technologies and enhance the functionalities of the DT by providing greater performance. The proposed work is implemented in an Industry 4.0 laboratory that is composed of Festo Cyber–Physical Factory and CP-Lab stations. The implementation of the architecture is based on ISO 23247, where the following requirements were considered for the design of DTs: (1) observable attributes and 3D design and visualization of all physical production lines in all of their stages, (2) a communication entity through the OPC UA protocol for the collection of state changes of manufacturing elements, (3) a DT entity where digital models are modeled and updated based on the collected data, and (4) user entities through the use of AR and VR to make manufacturing more efficient. The experimental results showed that the architecture enables interoperability between different platforms and control subsystems. It allows for the detection and diagnosis of problems during the execution of the production line; in addition, the high-fidelity simulation and AR and VR environments provided by the DT with data obtained in real time can improve the accuracy and efficiency of manufacturing through a more detailed analysis of the process, providing advantages such as interactive creation for customized products and continuous innovation.

Analysis of Behavioral Factors in the Use of Traditional Medicine: Observational Study in Yogyakarta, Indonesia

Traditional medicine has long been used by the people of Yogyakarta, Indonesia as an alternative treatment to modern medicine. Various factors influence traditional medicine use, including psychological factors such as attitudes, subjective norms, and perceived behavioral control. This research aims to determine the factors that influence the use of traditional medicine among the people of Yogyakarta Indonesia using the theory of planned behavior (TPB). This research was conducted using an analytical observational research design with a cross-sectional design. Data was collected from 110 respondents living in Yogyakarta who met the inclusion and exclusion criteria. The research instrument is a questionnaire that refers to the TPB construct which has been tested for validity and reliability. Data analysis was carried out using logistic regression statistical tests and Pearson correlation tests. The results of the analysis show that attitudinal factors and perceived behavioral control partially contribute to the intention to use traditional medicine, while the subjective norm construct does not contribute. Attitudes and perceived behavioral control are important factors that influence the intention to use traditional medicine among Indonesian people. This suggests that interventions that focus on increasing positive attitudes and perceived behavioral control can increase the use of traditional medicine.

Educational training and nursing professional self-perception in Mongolia: A prospective observational pre-post design study.

To determine whether professional self-perception of nurses in Mongolia improves following an educational intervention and to identify differences in scores among participant subgroups. A prospective observational pre-post design. Using a convenience sample of 67 nurses in Mongolia in 2019, the Nursing Professional Values Scale-3 instrument was used pre- and post-intervention. Independent and paired sample t-tests were conducted. Data were analysed using IBM SPSS 28.0.1.1 and Stata/SE 16.1. This study complied with the STROBE checklist. Of the 67 nurses, 92.0% were female, mean age was 32.15 years (SD 8.96), 70.0% held a bachelor's degree, 58.0% had 5 or more years' nursing experience and 51.0% were members of a professional nursing organization. After participating in the educational training, nurses reported higher overall professional self-perception as well as across subscales: activism, professionalism and caring. Considering the nursing shortage in lower-middle-income countries, it is important to recognise the influence of nurses' professional self-perception on nursing retention. This study highlights the significant role continuing educational opportunities play in increasing nurses' professional self-perception. It is imperative to explore ways of improving this perception and focusing on subgroups of nurses to help guide the use of limited resources. Further research is necessary to include nurses in other areas of Mongolia. Accurately assessing nursing professional self-perception and providing educational opportunities could improve nursing professional self-perception, nursing satisfaction, patient safety and nursing retention in lower-middle-income countries. What problem did the study address? This study meets the need for current study on the nursing professional self-perception of nursing from the perspective of nurses in Mongolia. It addresses the dangerous nursing shortage in Mongolia by determining if an educational intervention could improve nursing professional self-perception and thus improve nursing job satisfaction and retention. What were the main findings? Mongolian nurses in this study scored in the top quartile of the NPVS-3, indicating a baseline high NPSP. Educational intervention (including translated oral education and written clinical pathways) significantly improved the nurses' professional self-perception. Nurses were eager for training in other clinical and leadership topics. Where and on whom will the research have an impact? This research can be impactful for nurses, nurse leaders and policy makers in low- and lower-middle-income countries. Specifically for nurses in Mongolia, with increasing technologies and services such as cardiac catheterization laboratories becoming available, more education in these nursing specialty areas is imperative. Professional Nursing Organizations are poised to foster more educational offerings to their members and to increase membership. Nursing education provided by international volunteer nurses with Non-Governmental Organizations can improve NPSP in nurses in LMICs. This study complied with the STROBE checklist. No patient or public contribution.

Role of Sedentary Behavior as a Risk Factor for Hypertension and Obesity

Previous studies have shown that sedentary activity is closely related to an increased risk of hypertension and obesity. However, to understand the relationship between sedentary activity, hypertension, and obesity more deeply, this study involves further analysis. This study aimed to evaluate the relationship between sedentary activity and the risk of hypertension and obesity. This research is a quantitative study using an observational design, through a prospective cohort approach. Sedentary activity was measured using the Adolescent Sedentary Activity Questionnaire (ASAQ). The correlation between sedentary activity and the risk of hypertension and obesity was analyzed using the Spearman Rank correlation method. Sedentary activity becomes a risk factor for hypertension and obesity with a moderate correlation level (r=0.416). High levels of sedentary activity significantly increase the risk of hypertension. This study confirms the significant relationship between sedentary activity and the risk of hypertension and obesity. High levels of sedentary activity increase the risk of hypertension significantly. Therefore, it is recommended to encourage an active lifestyle and reduce sedentary activity to prevent hypertension and obesity.

Obstetric risk profiles and causes of death: Estimating their association with cesarean sections among maternal deaths in Mexico.

Maternal mortality is a critical indicator of healthcare quality, and in Mexico, this has become increasingly concerning due to the stagnation in its decline, alongside a concurrent increase in cesarean section (C-section) rates. This study characterizes maternal deaths in Mexico, focusing on estimating the association between obstetric risk profiles, cause of death, and mode of delivery. Utilizing a retrospective observational design, 4,561 maternal deaths in Mexico from 2010-2014 were analyzed. Data were sourced from the Deliberate Search and Reclassification of Maternal Deaths database, alongside other national databases. An algorithm was developed to extract the Robson Ten Group Classification System from clinical summaries text, facilitating a nuanced analysis of C-section rates. Information on the reasons for the performance of a C-section was also obtained. Logistic regression and multinomial logistic regression models were used to estimate the relation between obstetric risk factors, mode of delivery and causes of maternal death, adjusting for covariates. Among maternal deaths in Mexico from 2010-2014, 47.1% underwent a C-section, with a significant history of previous C-sections observed in 31.4% of these cases, compared to 17.4% for vaginal deliveries (p<0.001). Early prenatal care in the first trimester was more common in C-section cases (46.8%) than in vaginal deliveries (38.3%, p<0.001). A stark contrast was noted in the place of death, with 82.4% of post-C-section deaths occurring in public institutions versus 69.1% following vaginal births. According to Robson's classification, the highest C-section rates were in Group 4 (67.2%, p<0.001) and Group 8 (66.9%, p<0.001). Logistic regression analysis revealed no significant difference in the odds of receiving a C-section in private versus other settings after adjusting for Robson criteria (OR: 1.21; 95% CI: 0.92, 1.60). A prior C-section significantly increased the likelihood of another (OR: 2.38; CI 95%: 2.01, 2.81). The analysis also indicated C-sections were significantly tied to deaths from hypertensive disorders (RRR = 1.25, 95% CI [1.12, 1.40]). In terms of indications, 6.3% of C-sections were performed under inadequate indications, while the indication was not identifiable in 33.1% of all C-sections. This study highlights a significant overuse of C-sections among maternal deaths in Mexico (2010-2014), revealed through the Robson classification and ana analysis of the reported indications for the procedure. It underscores the need for revising clinical decision-making to promote evidence-based guidelines and favor vaginal deliveries when possible. High C-section rates, especially noted disparities between private and public sectors, suggest economic and non-clinical factors may be at play. The importance of accurate data systems and further research with control groups to understand C-section practices' impact on maternal health is emphasized.

Quality of Life in Patients with Chronic Low Back Pain and Differences by Sex: A Longitudinal Study.

The experience of chronic low back pain has a significant impact on the quality of life of affected people, resulting in difficulties in performing basic activities of daily living. To study the perceived quality of life of people affected by chronic low back pain and the associated factors by sex. A prospective, longitudinal and observational design was used. A total of 129 people (58.1% women) with chronic low back pain were studied. The mean pain intensity scores were of moderate severity (6.42 points), with a modest improvement at follow-up (6.17 points). Epidural nerve blocks were the most effective therapeutic intervention in reducing the intensity of pain. Participants described a negative perception of their health with regard to quality of life, with low scores for the two constructs both at baseline (health index, 0.444; perception of health, 38.76 points) and at follow-up (health index, 0.447; perception of health, 40.43 points). Participants had severe functional limitation scores (50.79 points). The results were significantly better among men. There was an inverse relationship between the average pain intensity (β = -0.304; p < 0.001), functional limitation (β = -0.466; p < 0.001) and mental health (β = -0.565; p < 0.001) and quality of life. The chronification of low back pain complicates people's biopsychosocial adaptation to life. There is a longitudinal inverse association between pain and functional limitation and health-related quality of life.

Development and Assessment of Learners’ Experiences with a Virtual Reality Learning Platform: Constructivist and Experiential Learning Pedagogies in Master of Physical Therapy Curriculum

Teaching competencies for psychomotor skill development for manual handling techniques in the cervical regions is necessary for safe practice in physiotherapy. However, grasping anatomy and palpation can be challenging for students, and practice in the lab can lead to discomfort for students. To facilitate teaching and learning of this complex skill, we worked in partnership with a virtual reality (VR) industry partner who developed a customized VR application focusing on transverse ligament stress testing for manual therapy skills for Master of Physical Therapy (MPT) students. In this scholarship of teaching and learning (SoTL) project, eight MPT students participated in the evaluation of an innovative VR learning experience for manual therapy in the cervical spine. Students’ learning experiences with the custom virtual reality learning application were assessed using an observational study design with semi-structured interviews. Interview questions aligned with constructs that are recommended to assess learners’ attitudes toward VR environments. Student participants appreciated the usefulness of the application for studying and practicing the transverse ligament stress test and provided recommendations for enhancing the learning experience.

This research aims to evaluate the effectiveness of the online queuing system. This study used a non-experimental observational design with a cross-sectional approach. Data was collected through a survey of 1000 patients who used the RSGM UMY online queue system. Data were analyzed using descriptive statistics and inferential statistical tests. The research results show that the RSGM UMY online queuing system is effective in reducing patient waiting time. The average patient waiting time with the online queuing system was 21.33 (SD 1.45) minutes, shorter than with the manual queuing system which averaged 112.32 (SD 8.23) minutes. Patients were also satisfied with the online queuing system, with 92.32 (SD 4.21) respondents stating they were satisfied. The online patient queue management system at RSGM UMY has proven effective in reducing patient waiting time and increasing patient satisfaction. This system can be a model for other RSGMs to improve the quality of their services.

Iterative algorithm to the generalized coupled Sylvester‐transpose matrix equations with application in robust and minimum norm observer design of linear systems

AbstractThis article consider a class of generalized coupled Sylvester‐transpose matrix equations which play an important role in control and systems theory. Based on the Jacobi iterative algorithm, the full‐row rank accelerated Jacobi gradient based iterative (RRAJGI) algorithm and the full‐column rank accelerated Jacobi gradient based iterative (CRAJGI) algorithm are proposed. By using the Frobenius norm of matrix and the trace function of matrix, the convergence of the algorithms are proved. The results show that the new algorithms are convergent for arbitrary initial matrices under the convergence number satisfies appropriate conditions. Numerical examples show that RRAJGI algorithm and CRAJGI algorithm have the advantages of faster convergence speed and higher convergence accuracy than other existing algorithms. Finally, an application example for robust and minimum norm observer design of linear systems is given.

Clinical outcome analysis of patients with multiple sclerosis – Analysis from the UK Medical Cannabis Registry

IntroductionWhilst disease-modifying therapies are the cornerstone for treatment of multiple sclerosis (MS), there is a need to develop novel therapeutics for the symptomatic sequalae of the disease. Cannabis-based medicinal products (CBMPs) have been suggested as a potential therapy for the associated pain, spasticity, and mental health disorders. However, there is a paucity of clinical evidence on CBMPs in MS. The aim of this study is to assess changes in MS-specific and general health-related quality of life (HRQoL) outcomes alongside adverse event incidence in patients prescribed CBMPs for MS from the UK Medical Cannabis Registry (UKMCR). MethodPatients prescribed CBMPs for MS symptoms for longer than one month were identified from the UKMCR. The primary outcomes were changes from baseline in MS Quality of Life-54 (MSQoL-54), Generalised Anxiety Disorder-7 (GAD-7), Single-Item Sleep Quality Scale (SQS), and EQ-5D-5L scales at one month, three months and six months. p < 0.050 was defined as statistically significant. Results141 patients met the inclusion criteria for the study. There was an improvement in the following subscales of the MSQoL-54 at 6 months: change in health scale, cognitive function, mental health composition, physical health, role limitations due to physical limitation and due to emotional problems, as well as social and sexual function (p < 0.050). There were also improvements in the EQ-5D-5L index value, GAD-7 and SQS (p < 0.050). 146 (103.55 %) adverse events were reported in total. Most were considered mild (n = 47; 33.33 %) and moderate (n = 72; 51.06 %). ConclusionsThis preliminary analysis demonstrates a possible association with improved general health-related quality of life in those prescribed CBMPs for MS. Moreover, the results suggest that CBMPs are well-tolerated in the first 6 months of treatment. However, this must be interpreted with caution considering the limitations of the observational study design.

Pleiotrophin serum level and metastasis occurrence in breast cancer patients.

Breast cancer (BC) cases in Makassar, Indonesia, are on the rise, with 2723 cases recorded in 2018. Tumor cells in the blood indicate metastasis, emphasizing the need for early diagnosis and monitoring. Pleiotrophin (PTN) is associated with various human malignancies, and recent studies suggest a correlation between PTN expression and advanced BC stages; therefore, PTN could serve as an independent predictor of metastasis. This study aimed to determine the correlation between serum PTN level, histopathological grading, and metastasis occurrence in BC patients in Makassar, Indonesia. This study used an observational cross-sectional design. Pleiotrophin serum levels were examined using enzyme-linked immunosorbent assays. This study used a t-test and ROC curve analysis for the statistical tests. Of the 64 samples used in this study, metastasis was present in 26 cases and absent in 38 samples. The mean PTN serum levels in metastatic and non-metastatic breast cancer patients were 4.311 and 1.253, respectively. The PTN receiver operating characteristic curve showed an area under the curve of 2.47 ng/dL, which was statistically significant (p < 0.001). A significant relationship was found between PTN level and metastasis (p < 0.001). The correlation coefficient was 0.791, indicating a positive correlation. This study revealed that the serum PTN level among breast cancer patients had a cut-off value of 2.47 ng/dL. The research established a clear correlation between PTN level and metastasis occurrence in breast cancer patients, indicating a higher likelihood of distant metastasis with elevated PTN concentration.

Research on High-Stability Composite Control Methods for Telescope Pointing Systems under Multiple Disturbances.

During the operation of space gravitational wave detectors, the constellation configuration formed by three satellites gradually deviates from the ideal 60° angle due to the periodic variations in orbits. To ensure the stability of inter-satellite laser links, active compensation of the breathing angle variation within the constellation plane is achieved by rotating the optical subassembly through the telescope pointing mechanism. This paper proposes a high-performance robust composite control method designed to enhance the robust stability, disturbance rejection, and tracking performance of the telescope pointing system. Specifically, based on the dynamic model of the telescope pointing mechanism and the disturbance noise model, an H∞ controller has been designed to ensure system stability and disturbance rejection capabilities. Meanwhile, employing the method of an H∞ norm optimized disturbance observer (HODOB) enhances the nonlinear friction rejection ability of the telescope pointing system. The simulation results indicate that, compared to the traditional disturbance observer (DOB) design, utilizing the HODOB method can enhance the tracking accuracy and pointing stability of the telescope pointing system by an order of magnitude. Furthermore, the proposed composite control method improves the overall system performance, ensuring that the stability of the telescope pointing system meets the 10 nrad/Hz1/2 @0.1 mHz~1 Hz requirement specified for the TianQin mission.
