Authors: Jain Meena , Srivast Roomani , Singh Arundeep , Jain Vishal , Gupta Alpa
Published: January 2025

Introduction: While many dental schools in India still follow traditional assessment systems, some are transitioning to credit-based assessment, allowing the integration of research and evidence-based practices into the curriculum. This research paper outlines a systematic approach taken by a dental school in India to introduce a research-teaching course for undergraduate dental students, named the "Research & Innovation Catalyst (RIC)." The course aims to establish a comprehensive research teaching nexus in the dental curriculum from the early years. Methodology: The curriculum was redesigned to incorporate outcome-based education and a choice-based credit system. Inputs from all the stakeholders were taken to create the dental undergraduate curriculum, ensuring alignment with the Dental Council of India (DCI) guidelines. The RIC course was introduced as an addition to the mandatory requirements of the DCI and was structured to teach research methodologies, survey techniques, ideation, innovation, intellectual property rights, and biostatistics over the first three years of graduation. A course development team conducted qualitative needs assessments involving experts, students, alumni, and faculty members. The syllabus was formulated on the basis of identified themes from needs assessment, and literature, and was subjected to Delphi rounds by a course development team. Both formative and summative evaluations were implemented, including assignments, tests, paper presentations, and viva voce examinations. Students practically learnt research principles through the mentor-guided research project. Results: An evaluation after three years of complete implementation of the designed course revealed that students' confidence and competencies in research domains increased as they progressed through the program. The students reported improved skills in scientific literature comprehension, problem-solving, critical thinking, and motivation to construct a research profile. Faculty members expressed confidence in their students' abilities but suggested additional exposure to evidence-based research and diverse types of articles. Conclusion: The successful implementation of the RIC course has the potential to increase research competence among dental undergraduates. This initiative contributes to producing dental graduates capable of applying research-based strategies in clinical practice and pursuing research careers, ultimately fostering research-oriented dental professionals.

Published: January 2025

In this study, the effects of utilizing a vibro-impact electromechanical device to suppress undesired vibrations are investigated. The demonstrated vibro-impact system serves as a vibration suppressor and provides the necessary energy for its sensors and control components, making it a potentially autonomous system. The electromechanical equation of motion for the system under examination is calculated and experimentally verified. Also, the effect of adjusting the gap size, a crucial parameter of the Vibro-impact system, on its electromechanical performance of the system is investigated. Additionally, the effectiveness parameter is announced as a parameter that results in enhancing the energy harvesting and vibration-suppressing capabilities of the demonstrated vibro-impact system. Finally, it is demonstrated that the characteristics of the electromagnetic vibro-impact system can be tuned as an effective autonomous semi-active impact damper system.

Background: Falls represent a significant public health concern, particularly among the elderly. Chronic kidney disease (CKD) is a multifaceted condition associated with frailty, sarcopenia, and polypharmacy, all of which increase the risk of falls. This study aimed to evaluate the association between CKD severity and the risk of falls among elderly individuals in Birjand, Iran.
Methods: This prospective cohort study included 1,344 elderly participants from the Birjand Longitudinal Aging Study. CKD severity was classified based on estimated glomerular filtration rate (eGFR), and falls were self-reported at specified intervals. Logistic and Cox regression models were used to examine the association between CKD severity and fall risk.
Results: Fallers (n=82) were older, predominantly female, and had a higher prevalence of comorbidities compared to non-fallers (n=1,262). Mild CKD was significantly associated with increased odds (OR:1.98, 95% CI: 1.23–3.18, p=0.005) and hazard (HR: 2.22, 95% CI: 1.38–3.58, p=0.001) of falls in crude models. However, after adjusting for confounders, these associations became weaker and even non-significant (OR: 1.39, 95% CI: 0.83 – 2.31, p=0.209 and HR: 1.67, 95% CI: 1.01 – 2.77, p=0.047). Severe CKD was not consistently associated with fall risk in any models.
Conclusion: Mild CKD is associated with an increased risk of falls in older adults; however, this relationship is influenced by confounders such as sex, comorbidities, and anthropometric factors. The findings underscore the importance of addressing fall risk through multifaceted interventions targeting comorbidity management in elderly CKD patients.

A comprehensive understanding of anatomical structures is essential for medical and healthcare
students, as it forms the foundation for clinical evaluations, surgical interventions and diagnostic imaging. The conventional methods employed in anatomy education, which mainly comprise the use of textbooks, lectures and cadaver dissections, could be improved. Such changes could include converting two-dimensional anatomical representations into three-dimensional (3D) structures to help address the ethical and logistical challenges related to cadaver use. Due to technological advancements, 3D technologies, such as virtual reality, augmented reality and mixed reality, can provide students with immersive and interactive learning experiences that improve their understanding of complex anatomical linkages and spatial orientation. Furthermore, 3D models offer a practical and morally acceptable alternative to the use of accurate cadaveric material. Research has shown that 3D models increase student involvement and enthusiasm. Despite the numerous
advantages of incorporating 3D technology into anatomy education, several barriers must be
addressed. These include faculty training and the significant financial investment needed to acquire equipment and licenses. Additionally, senior faculty members may face challenges in adapting to new technologies. Notwithstanding these obstacles, 3D technologies are valuable due to their longterm advantages, such as improved educational quality and the potential to attract higher numbers of students. By incorporating such technological advances in anatomy instruction, educational institutions can enhance students’ preparation for the challenges of modern clinical practice and create dynamic and engaging learning environments.

Interprofessional online learning (IOL) is reported to increase students’ competency, yet a crucial
concern revolves around the potential negative impact of ineffective online learning on education.
Therefore, this study investigated the correlation and comparison between students’ readiness in
health professions and collaborative competency attainment on IOL. This study used proportionate
random sampling with 99 undergraduate health profession students. Students’ readiness and
collaborative competency were assessed by adopting a validated and reliable Readiness for
Interprofessional Learning Scale (RIPLS) and Interprofessional Collaborative Competency Attainment
Scale (ICCAS) through an online survey by Google Forms. In addition, the implementation of IOL
coincided with the three months following the initial global outbreak of COVID-19. The results showed
that students’ interprofessional education (IPE) experience correlated with collaborative competency
with a p-value of 0.020 (< 0.05) and r-value of 0.841. Readiness and collaboration also showed a
significant correlation with a p-value of 0.006 (< 0.05) and r-value of 0.275. However, there was no
significant difference between the two variables among the professions, with p-values of 0.37 and
0.84 (p > 0.05). To sum up, this study adds significant understanding to the relationship and contrast
between healthcare students taking part in the IOL, their readiness for interprofessional learning,
and their attainment of collaborative competency. Additional research is necessary to examine the
long-term impacts of interprofessional learning experiences on the development of collaborative
competence and to assess how well novel pedagogical strategies might foster interprofessional
collaboration among health profession students.
Understanding mobile banking adoption via the technology acceptance model: evidence from Jordan
Authors: Waleed Rababa Bara , Ali Azwadi , Montaser Mohammad Al
Published: January 2025

This paper studies the use of mobile banking in Jordan and the factors affecting its adoption through the Technology Acceptance Model (TAM). It examines user behavior across new banking technologies and resistance to adoption, focusing on factors such as perceived ease of use, usefulness, cost, social influence, and trust. The study employed convenience sampling because of privacy restrictions and the lack of a reliable customer database. 498 individuals completed a structured questionnaire, and 437 of them provided valid answers (87.8%). Using a 5-point Likert scale, the questionnaire evaluated demographic information and opinions about the adoption of mobile banking. The responses were analyzed using SmartPLS software. The results reveal that perceived usefulness is a key predictor of the willingness of the Jordanian population to adopt mobile banking. Perceived risk also positively impacts mobile banking usage, while perceived ease of use presents a moderate but significant barrier to adoption. Perceived ease of use also has a significant influence on perceived usefulness, which mediates its effect on adoption. While social influence plays an important role in adopting mobile banking services, trust does not directly affect the intention to use these services.

Research on Patient Outpatient Visit Decision-Making Model and Real-Time Monitoring System Based on Stream Computing (Preprint)
Authors: Ren Xiaoyang
Published: January 2025

BACKGROUND

With the increase in the number of primary healthcare institutions, their patient volumes have relatively decreased, while tertiary hospitals have seen a significant rise in patient visits. The imbalance between the proportions of different types of medical institutions and patient visit frequencies in China leads to inefficient use of healthcare resources.

OBJECTIVE

Analyzing hospital outpatient scenarios and studying factors influencing patient clinic visits is crucial for optimizing hospital outpatient resource allocation.

METHODS

This study first analyzes the queuing behavior patterns of patients when making appointments at outpatient clinics, establishing a service value model for patient clinic visits. Based on this value model, we can estimate the average visit time for patients. Using the M/M/1 queuing model, we calculate the longest tolerable queue length for patients. Additionally, we construct a highly scalable data processing service system to ensure the integrity of patient visit data and use stream computing methods to real-time calculate indicators related to patient decision-making patterns.

RESULTS

We built a service value model for patient outpatient visits and monitored patient visits in real time based on historical patient visit information through a scalable stream computing system. The experimental results show that the response time of the system can be completed in a few seconds, which can meet the requirements of real time in practical applications.

CONCLUSIONS

This study establishes a patient clinic visit decision-making model based on the service value patients receive and develops a highly available and scalable information distribution processing middleware to collect patient visit data and perform real-time calculations. The system provides indicators such as patient visit times and the longest tolerable queue length, which help optimize resource allocation and improve patient satisfaction.

Published: January 2025

Bathymetric mapping is crucial for marine spatial planning and coastal infrastructure development. However, shallow waters with depths ranging from 0 to 5 meters are considered critical areas that pose dangers to conventional survey vessels. This research examines a bathymetric mapping method for the shallow waters of Kepulauan Seribu, Jakarta, using aerial images captured by an unmanned aerial vehicle (UAV) with a structure-from-motion (SfM) approach. Furthermore, the point cloud must be corrected for the refractive index since light passes through both air and water. The seawater refractive index is derived from salinity and seawater temperature data. The validation process uses several independent control points (ICPs) obtained from GNSS real-time kinematic (RTK) measurements and soundings conducted with an unmanned surface vessel (USV). The accuracy assessment shows that the SfM point cloud data has a horizontal RMSE of 0.103 m and a vertical RMSE of 0.191 m. The aerial image approach significantly speeds up the acquisition process compared to conventional sounding methods and produces a higher density of point clouds, integrating the coastal digital elevation model (DEM) of both land and sea areas. However, the use of this method is limited to clear waters where the seabed is visible in the images.

Published: January 2025

Waduk Mrica merupakan infrastruktur vital yang berperan sebagai Pembangkit Listrik Tenaga Air (PLTA), sumber irigasi, pengendali banjir di bagian hilir, dan perikanan. Kemampuan waduk untuk menjalankan fungsinya tergantung pada kapasitas penyimpanannya, yang dipengaruhi oleh tingkat sedimentasi akibat erosi pada Daerah Aliran Sungai (DAS). Untuk mengatasi masalah pendangkalan dan dampak erosi tanah, diperlukan pemahaman mendalam mengenai tingkat bahaya erosi dan nilai sedimentasi dalam periode waktu tertentu. Penelitian ini bertujuan memberikan gambaran menyeluruh mengenai laju erosi di DAS Serayu dan dampaknya terhadap pendangkalan Waduk Mrica dalam rentang waktu 2018-2022 dengan memanfaatkan citra satelit Sentinel-2. Penelitian meliputi prediksi laju erosi DAS Serayu menggunakan metode Universal Soil Loss Equation, kemudian dilakukan estimasi kedalaman Waduk Mrica dengan algortima Random Forest yang dikalibrasi dengan data perekaman batimetri in situ. Hasil penelitian ini menunjukkan estimasi kedalaman menggunakan citra Sentinel-2 mampu memberikan informasi kedalaman 0-25 m di Waduk Mrica pada periode 2018-2022, dengan nilai R2 pada rentang 0,83-0,92, MAE pada rentang 0,367-0,593, RMSE pada rentang 0,819-1,401 m. Hasil penelitian menunjukkan tren penurunan total volume Waduk Mrica dari tahun 2018 hingga 2022, menandakan berkurangnya kapasitas penyimpanan waduk. Terjadi variasi laju erosi, total erosi, dan sediment yield di DAS Serayu selama periode tersebut. Sub DAS Serayu Hulu secara konsisten menjadi kontributor terbesar terhadap total erosi dibanding Sub DAS lainnya. Terdapat hubungan antara sedimen hasil erosi DAS Serayu dan pendangkalan Waduk Mrica pada tahun 2019 dan 2020, tetapi pada tahun 2021 dan 2022 terjadi ketidaksesuaian di mana sedimen DAS meningkat sedangkan sedimen waduk menurun yang disebabkan adanya tindakan pengendalian sedimen waduk.
The Application of Amino Acid Racemization Geochronology of Tubipora sp. in Marine Terraces of Manokwari Region, West Papua, Indonesia
Authors: Hidayat Rahmadi , Saputra Sukahar Eka Adi , Husein Salahuddin
Published: January 2025

The active neotectonics of northern West Papuan coastlines allow the formation of emergent marine terraces associated with Quaternary sea-level high stands. These terraces contain fossils from the coral assemblage, which are useful for geochronological assessments and further estimating uplift rates. Here, we report the applicability of amino acid racemization (AAR) of Tubipora sp. to discriminate different ages associated with stages of sea-level high stand, constrained by previous uranium-thorium (U/Th) series dating. The results from amino acid dating of three samples reveal two distinct extents of racemization corresponding to terraces developed during Marine Isotope Stage (MIS) 5 sensu lato and 1. However, AAR analysis could not further discriminate interstadial MIS 5a and 5c as determined by published radiometric dating. This indicates the low resolving power of amino acid dating to distinguish sub-sequences beyond the interglacial period. Nevertheless, the cost-effective and rapid analysis of AAR dating of Tubipora sp. can be used as preliminary results related to marine terraces formed in different interglacial events.

The southern American genus Praxelis Cass. has 18 species. In Singapore and Indonesia, notably Java, P. clematidea R.M.King & H.Rob. has naturalised. The first record in Indonesia was in Bogor in 2018, although it is unverified elsewhere. Praxelis clematidea was found in Bangka, Belitung, Jambi, Lampung, and Palangka Raya during our exploratory field research in 2020–2023. The naturalised populations proliferate in roadsides, ditches, open spaces, and disturbed areas.  It thrives in a small swampy peat environment in Palangka Raya. Praxelis clematidea has been found outside Java, suggesting it could become an invasive alien species in Kalimantan and Sumatra.

Published: January 2025

This paper discusses about the bioerosion discovered in carbonate tests of Discocyclina discus sowerbyi (Nuttall, 1926), a large benthic foraminifera from the Priabonian (Late Eocene). The study material was sampled from the Gamping beds in the Wungkal-Gamping Formation in Bayat, Indonesia. We discovered four bioerosional trace fossils from three different ichnogenera demonstrate bioerosion from the surface test analysis. Oichnus simplex and Oichnus paraboloides are ichnogenus Oichnus diagnostic drilling holes that are often found on the surface. Caulostrepsis isp. exhibits the presence of uncomplicated U-shaped borings. The observed formation of drill holes can be mostly linked to the predatory behaviour of gastropods, while other trace fossils are predominantly associated with the burrowing activities of worms. The occurrence of well-preserved individual tests exhibiting no signs of bioerosion is infrequently observed in D. discus sowerbyi. In addition, bioerosion occurs more frequently in the microspheric generation than in the megalospheric generation. This research also demonstrates for the first time in Indonesia that parrotfish bite marks have developed on individual tests of the microspheric generation of D. discus sowerbyi. The taphonomic characteristics exhibited by the bioeroded and encrusted D. discus sowerbyi specimens can serve as reliable paleoecological indicators for sediment deposition occurring at an intermediate to high sedimentation regime. The occurrence of larger foraminifera with some bioerosional trace fossil highly proficient at documenting shallow marine sclerobionts.

Published: January 2025

Rubber mini-seedling budding have the characteristics of short nursery cycle, low labor intensity, large number of seedlings per unit area, easy transportation and planting, well-developed taproot and intact root system, high post-planting survival rate, fast growth, strong tolerance to drought, wind and cold, and early tapping. The quality of rubber tree axillary buds is a key factor affecting the budding of rubber mini-seedling buddings, and there are many environmental factors affecting the quality of rubber tree axillary bud. Production practice shows that moderate shading is beneficial to the quality of rubber bud stick. However, there is still a lack of systematic research on the effect of light on the quality of rubber tree axillary bud. This study set up two treatments with 75% and 100% light intensity based on production practice to observe and analyze the phenology and axillary bud morphological indicators of rubber tree leaf whorl. The results showed that axillary buds of the 3rd leaf whorl had the highest quality under 75% light intensity. Suitable light intensity promotes axillary buds to grow more robustly. Taken together, light has a significant impact on the quality of rubber tree axillary bud. Suitable lighting is more conducive to improving the quality of rubber tree axillary bud and laying a good foundation for the subsequent growth and development of rubber mini-seedling budding.

Published: January 2025

The internal combustion engine operates in unsteady modes for a significant part of the time when the vehicles is moving. This is unavoidable for vehicles with traditional power plants for the following reasons: 1) the need to regulate the power on the driving wheels, 2) the effective performance and environmental qualities of the engine in unsteady modes are often worse in relation to those in steady-state modes of operation; this is due to the influence of many factors and has been studied in many well-known scientific papers. Experimental studies of current fuel consumption, effective torque and environmental qualities of the engine at unsteady speeds are relevant. This is due to the complexity of the processes that take place in the units. Their main goal of these studies is to ensure greater adaptability of the internal combustion engine and power plant to work in unsteady modes. The methodology for determining the current fuel consumption when operating in an unsteady mode of an automobile internal combustion engine with external mixing and a dead-end fuel ramp with distributed gasoline injection through electromechanical injectors is improved in this article. An experimental study was carried out in the work. The injectors of the Denso 23209-39295 model of the 2ZR-FXE engine of the Toy-ota Prius PHV 4th generation vehicles is selected as an example. The fuel pressure drop, the duration of the electric control pulse and the magnitude of the electric voltage are considered as parameters that affect the volumetric performance of the injectors. The Autool ST160 stand and additional electronic equipment devel-oped by the authors were used in the study. The result of the study is an analytical device for more accurate determination of the current fuel consumption in unsteady engine operating modes. The improved technique does not require the installation of additional sensors and equipment on the vehicles.

Objective: The aim of this study was to evaluate the early experiences of prostate artery embolization (PAE) in patients with benign prostatic hyperplasia (BPH).
Material and methods: This retrospective study included all patients treated for BPH who were referred to the radiology department for PAE in Västmanland between 2018 and 2021. Data were collected on patient demographics, International Prostate Symptom Score (IPSS), prostate-specific antigen level, and peri- and post-procedure outcomes. Clinical success was defined as a decrease in the IPSS by ≤3 points or catheter freedom.
Results: A total of 96 patients (median age 74 years) underwent PAE. Before PAE, 65% of the patients were treated with α-blockers and 83% with 5α-reductase inhibitors. Clinical success was achieved in 60 patients (63%). Among catheterized patients, 33 (53%) achieved catheter freedom. In the non-catheterized group, 27 (79%) experienced clinical success. No significant differences in outcomes were observed based on the presence of a median lobe.
Conclusions: PAE appears to be a viable treatment option for BPH and may provide substantial symptom relief and catheter freedom for most patients. These findings suggest that PAE may be an effective alternative to more invasive procedures. Further research is needed to refine the patient selection criteria.

The issue of reading literacy is a frequently discussed topic in the Indonesian education system. However, the main problem does not lie in the literacy activities themselves but rather in the reading materials provided for children. This research aims to analyze how elementary school teachers choose reading materials for their students. It utilizes a qualitative method with a case study approach. Data collection involves observation, interviews, and documentation in four different elementary schools. The primary sources of this research are the interviews and observations conducted with teachers of upper-grade classes (grades 4, 5, and 6). An interesting finding in this research is that elementary school teachers select children's literature based on literary elements and its relevance to the Indonesian language teaching materials. For a more comprehensive explanation, this aspect is further discussed in the article. In conclusion, elementary school teachers choose reading materials based on the intrinsic elements of the work, and there is no comprehensive assessment in the selection process.

Learning mathematics is a challenge that is often faced by students at various levels of education because learning mathematics tends to be too theoretical, less contextual, and varied so students' interest in learning mathematics decreases. Lack of context in learning mathematics that links students' culture and everyday life so students have difficulty understanding the material. This study aims to produce ethnomathematics-based learning videos that use traditional cakes as a learning context for spatial recognition material for first-grade elementary school students. The traditional cake was chosen as a culturally relevant context to introduce students to the basic concepts of geometric shapes. The ADDIE development model was used with data collection instruments using observation and interviews with teachers and students. The research subjects included media experts, material experts, users, and first-grade elementary school students who were declared very valid with the results of the media expert test score of 100%, material experts 90.9%, and users 100%. Product practicality based on small-scale trials gets a percentage of 100% and large-scale gets a percentage of 97% for first-grade elementary school students. From these results, it can be stated that traditional cake ethnomathematics-based learning videos are interesting and practical to use.

The low numeracy ability in first grade of elementary school has a significant impact on the understanding of numeracy concepts at the next level of education. This study aims to prove the influence of learning using Bundle of Stick media on students' understanding of numeracy concepts. This objective was determined considering the low understanding of numeracy concepts in elementary school students. This study uses a quantitative experimental method with the True Experimental Design type. Data were collected through observation and multiple-choice assessment test sheets. This study used a sample of 24 students in each class. Data analysis was carried out using the T-test and Paired Sample T-test. The results of the independent sample t-test showed a significance value of 0.00 <0.05, which means that the null hypothesis (H0) was rejected and the alternative hypothesis (Ha) was accepted. This shows that students' understanding of numeracy concepts will be better if the Bundle of Stick learning media is applied compared to conventional learning. Furthermore, the results of the Paired Sample t-test showed a significance value of 0.00 <0.05, which means that Ha was accepted and H0 was rejected. This shows that the application of Bundle of Stick learning media can improve the understanding of numeracy concepts. Based on these findings, it can be concluded that the innovation of implementing Bundle of Stick media is effective in improving the understanding of numeracy concepts of first grade students. This study has implications for strengthening students' numeracy skills, so that they are more ready to receive material at the next level of education.
