The battery system in electric vehicles needs proper monitoring and control to ensure reliable, efficient, and safe operation. Recent advancement in cyber-physical technology has brought the emerging digital twin concept. This concept opens a new possibility of real-time condition monitoring and fault diagnosis of the battery system. Although it sounds promising, the concept implementation still faces many challenges. One of the challenges is the availability of a platform to develop digital twins, which involves data pipelines and modeling tools. The data pipeline will include the acquisition, storing, and extract-transform-load (ETL) with high velocity, volume, value, variety, and veracity data, known as big data. The modeling tools must provide applications to build the high-fidelity model, one of the required elements of the digital twin. Based on those urgencies, this paper proposes a platform that facilitates a digital twinning of the battery system in an electric vehicle. The platform is built on the open-source framework CDAP, equipped with a data pipeline and modeling tools. It has run several performance tests with different computation resource configurations and workloads. Doubling the processing power can reduce 12% of computation time while increasing memory size by four times only reduces 10% of computation time. The result shows that the processing power affects the performance digital twin platform more than the memory size.

The development of autonomous vehicle systems has progressed rapidly in recent years. One challenge that persists is the capability of the autonomous system to respond to human drivers. Human behavior is an integral part of driving; thus, driver behavior determines changing lanes and speed adjustments. However, human behavior is unpredictable and immeasurable. Some traffic accidents are caused due to the erratic behavior of the driver. Although, traffic laws, such as in Indonesia, regulate the use of lanes concerning the vehicle’s speed. The drivers’ behavior in the lane is more likely to be influenced by the regulation. This paper proposes a novel method of predicting drivers’ behavior by utilizing the concept of fuzzy Hidden Markov Model (fuzzy HMM). HMM has been proven reliable in predicting human behavior by observing measurable states to determine unmeasurable hidden states. The use of fuzzy logic is to mimic the way that humans perceive the speeds of other vehicles. The fuzzy logic determines the relative observed state of other vehicles according to the measured velocity of an ego vehicle and the observed state of observed vehicles. Observation data is obtained by equipping an ego vehicle with an action camera. The observed data, in the form of a video, is then discretized every 2 seconds. The resulting sequence of images is processed to determine several variables: speed and state of the observed vehicles (lane position and speed) and the time instance of the observation. The fuzzy HMM is generated based on observational data. A predictor created using fuzzy HMM equipped with a training and prediction algorithm successfully predicts the behavior of other drivers on the road.

The commonly used form of transportation mostly relies on-road vehicles nowadays. A vehicle is a mechanism to commute between places with higher efficiency and less time consumption. A vehicle usually consists of multiple working components, in which the engine is well-known to be one of its most crucial components. Although it can be considered the most vital component in a vehicle, the knowledge gaps for an engine are still unlimited. So much more potential can be explored for an engine to reach its maximum capabilities. Part of the perspective that should be explored is to study the engine’s thermal properties. This paper aims to investigate the effect of varying temperatures at the exhaust manifold under a certain amount of time spans. The temperature varied from low to high and vice versa for 6 cycles. The results revealed that the exhaust manifold had undergone an alteration in the strain of the body’s elasticity. Because of that, the displacement of the exhaust manifold, load distribution, and direction have also been affected.

Use of High-Fidelity Simulation in Clinical Teaching: Nurse Educators’ Perspective
Authors: C. Pananganan Joana Mariz
Published: July 2023

Background: Despite the benefits of high-fidelity simulation (HFS) in developing clinical skills, Nursing schools in lower-middle-income countries like the Philippines are less successful in the implementation of HFS as a pedagogy. The utilization of HFS was recommended to offset the effects of COVID-19 on clinical placements which received various reactions from nurse educators. Objective: This study aimed to explore the views of nursing educators who did not use HFS as an instructional strategy in nursing education. Methods: A qualitative descriptive research design was utilized and data were gathered through a focus group discussion involving seven nurse educators who fit the criteria. Using thematic analysis, the following themes were uncovered: (1) technological complexities and difficulties, (2) lack of training and application, (3) need for expert support, (4) inadequate resources, (5) fear and apprehensions, and (6) not a requirement but an option. Results: Multiple factors affect the use of HFS among nursing educators in a lower middle-income country that requires users to be knowledgeable, skillful, and technologically adept. The lack thereof coupled with fear has consequently reduced HFS to an option rather than an indispensable tool for nursing education. Conclusion: Hence, to facilitate the utilization of HFS, a structured HFS training program that considers the context, and faculty needs might be instrumental. Additionally, the likelihood of integrating HFS in the curriculum as an equivalent to clinical placements can be explored to future-proof nursing education from the effects of a pandemic.

Background: Currently, the prevalence of diabetes mellitus is a serious concern on a global scale. Most type 2 diabetes cases are the result of many factors that also lead to metabolic problems with a wide range of consequences. Objective: This study aims to identify the effects of web-based educational programs on diabetic self-efficacy management (DSEM) and diabetic self-care behavior management (DSCM) in quality of life (QoL) among type 2 diabetes patients in public hospitals. Method: This study used a quantitative quasi-experimental design with a pre-test and post-test. The Diabetic-N-Care program was conducted at Orthopedic Clinic Hospital Sultanah Nur Zahirah Kuala Terengganu for 34 days, where purposive sampling involved type 2 diabetic patients who were divided into intervention groups (IG) (n = 60) and control groups (CG) (n = 60). Respondents are the same individuals for each phase of measurement. Results: The general linear model repeated measures ANOVA, split-plot ANOVA (SPANOVA), and paired t-test were conducted on 120 patients to see the effect of using Diabetic-N-Care on IG. The results of the split- plot ANOVA analysis showed a significant overall effect of DSEM, DSCM, and QoL (p = 0.000) on IG. Meanwhile, in paired t-test analysis, there was a significant mean difference in DSEM, DSCM, and QoL at pre-test and post-test (p = 0.000) for IG compared to CG. Conclusion: Web-based health education can have an impact on DSEM and DSCM in the QoL of type 2 diabetic patients where there is greater confidence to change the old behavior to a new behavior to improve quality of life in the long term. Therefore, this study concludes that web-based methods such as Diabetic-N-Care need to be widely adapted into current health education methods.

Hemifacial spasm: a neurosurgical perspective
Authors: Kaufmann Anthony M.
Published: July 2023

Hemifacial spasm (HFS) causes both physical and psychological disabilities that significantly impact quality of life. Medical management with serial botulinum toxin injections provides transient spasm relief and is widely reported as highly effective, as compared to no treatment. While there is an excellent potential for disease cure with microvascular decompression (MVD) surgery, utilization rates remain very low in North America (approximately 10%) and many patients are not adequately informed of this surgical option. Although the majority of MVD neurosurgeons maintain a low annual case volume, excellent safety and success rates can be achieved with attention to technical nuances and anatomical appreciation of the target facial root exit zone. Attention to better informing patients and optimizing surgical outcomes should lead to a greater role for neurosurgery in the treatment and cure of HFS.
High signal intensity of the intraaneurysmal sac on T1 CUBE imaging as a predictor of aneurysm stability after coil embolization

Published: July 2023

OBJECTIVE

Histopathological studies of aneurysms after coil embolization showed that thrombus formation during the first month after endovascular treatment (EVT) played an important role in the healing process. The authors hypothesized that dedicated T1-weighted imaging may be used to predict stable aneurysms by visualizing the thrombus status within coil-treated aneurysms. Therefore, this study investigated the relationship between the signal intensity (SI) of the intraaneurysmal sac after coil embolization and aneurysm stability.

METHODS

The study population included 82 patients with 86 aneurysms who underwent T1-weighted 3D black-blood fast spin-echo (T1 CUBE) imaging within 1 month after coil embolization between 2019 and 2022. The relative SI of a coil-treated aneurysm (RSIcoiled) was calculated as follows: the mean SI of the intraaneurysmal sac/the mean SI of the genu of the corpus callosum. Aneurysms with enlarged remnants on MR angiography (MRA) within 6 months after EVT were defined as recurrence, while a decrease of intraaneurysmal flow on MRA was defined as improved embolization status. Stable aneurysms were defined as improvement or no change in embolization status 6 months after coil embolization. The volume embolization ratio (VER) was calculated as the ratio of the packed coil volume to the aneurysm volume. Differences between stable and recurrent aneurysms were examined. All aneurysms were divided into high and low RSIcoiled groups based on the cutoff value of RSIcoiled, and differences between the two groups were also evaluated.

RESULTS

Recurrence was confirmed for 26 of 86 aneurysms. A univariable analysis showed that small aneurysms, high VER, and high RSIcoiled were associated with aneurysm stability. In the receiver operating characteristic curve analysis, the optimal cutoff value for RSIcoiled to differentiate stable from recurrent aneurysms was 0.54. The cutoff value for RSIcoiled was selected as 0.50 (sensitivity 0.77, specificity 0.70) because it was half the value of the SI of the corpus callosum and close to the optimal cutoff value. In a multivariable analysis, RSIcoiled > 0.50 (OR 8.1, 95% CI 2.5–27) remained a significant factor for aneurysm stability. The high RSIcoiled group showed a higher rate of an improved embolization status (26% vs 6.1%, p = 0.022) and stable aneurysms (85% vs 15%, p = 0.0002).

CONCLUSIONS

RSIcoiled was associated with postcoiling aneurysm stability. High RSIcoiled might imply intraaneurysmal thrombus formation associated with the healing process of coil-treated aneurysms.

Published: July 2023

Technological advancements have rapidly impacted society, transforming the way gadgets are utilized for social interaction. Among students, the use of gadgets for socializing has been on the rise. However, differences in interaction patterns between gadget-mediated and face-to-face interactions have yet to be fully understood. Therefore, this study aims to investigate student social interaction activities through gadgets and in real-life settings. Additionally, the research explores social interaction patterns and experiences among students at SMA IT Plus Bina Bangsa Sejahtera Bogor, a high school that initially prohibited smartphone use during learning but later modified their policy prior to the Covid-19 pandemic. A descriptive qualitative approach was employed, utilizing observation, documentation, and interviews with 30 randomly selected respondents. The study was conducted over a two-month period, from January to February 2023, at SMA IT Plus Bina Bangsa Sejahtera Bogor. The analysis reveals that gadget-mediated interaction patterns involve cooperation, accommodation, assimilation, acculturation, competition, and opposition. Prolonged gadget usage for extended hours was observed, emphasizing their significance in students' lives. Interpretation of gadget-mediated text messages sometimes leads to misunderstandings. However, communication differences between virtual and face-to-face interactions were minimal, as both modes effectively addressed problems. This research deepens our understanding of student social interaction dynamics and highlights the impact of gadget usage on interpersonal communication. It provides insights for schools, families, and policymakers to enhance positive gadget usage and improve the quality of student interactions.

Published: July 2023

Calculating the total impedance between two points that are equivalent and connected to a current voltage source still revolves around the discussion using the Wye-Delta transformation, the theory of the Series-Parallel formula, the loop current method and the node or node voltage method. These calculations are still ineffective and take quite a long time for certain complex circuits, because the calculations can only be done manually. So we need a special solution to facilitate us in the calculation process. In this case it is necessary to do a new transformation approach called Transformation [C]. This [C] Transformation Matrix will connect the old and new equivalent circuits. This study uses the Borland C++ Builder program with four kinds of complex circuit conditions tested. From the test results it can be seen that the results of program calculations are the same as the results of manual calculations and are proven to be easier, more effective and efficient than manual calculations which are complicated and require a long and lengthy calculation process. This software is very helpful and can be applied to calculate the total impedance of an electrical circuit system, especially in certain cases of conditioned complicated circuits.
