Service Advisor in Automotive Service Centre plays an important role as the frontline in providing exceptional services. The automotive service centre has to adopt big data applications in understanding customers’ needs by collecting data promptly and analysing scientifically. The objective of this paper is to evaluate Customer Satisfaction (CS) and Service Advisor Experience (SAE) scores via an online survey based on big data analytics. Thus, applying a Quadrifid graph in identifying focus regions for improvement activities. The application of big data online survey platforms is an efficient way of gathering customer feedback for continuous improvement activities. The study focused on Service Advisor (SA) services throughout Malaysia with selected one automotive brand. It explains the definition of customer process and customer satisfaction by comparing high-density customer regions namely Central, Northern and Southern regions with low-density customer regions namely East Coast and East Malaysia regions. There are five steps in deriving the output, which are the consolidation of customer data, customer selection, survey execution, score calculation and analytical report. Thus, the big data applications analyse the expectation SA gap and propose recommendation actions. The online survey results achieved a minimum of 879.90 points for Customer Satisfaction while Service Advisor Experience was minimum at 73%. SA achieved a high score for portraying courtesy and professionalism, while a lack of performing the visual inspection is the main gap for all regions. Detailed analysis using Quadrifid graph interpreted Southern region recorded the lowest correlation with R-square value less than 0.1 and level of CS & SAE below the average value of 800 relates to response towards needs by SA.

Such indicators lead to the SA’s professionalism in managing customer expectations.
Monocaprin Enhances Bioavailability of Fucoxanthin in Diabetic/Obese KK-Ay Mice

Fucoxanthin is a marine carotenoid found in brown seaweeds and several microalgae. It has been reported that fucoxanthin has health benefits such as anti-obesity and anti-diabetic effects. To facilitate fucoxanthin applications in the food industry, it is important to improve its low bioavailability. We attempted the combined feeding of fucoxanthin-containing seaweed oil (SO) and monocaprin in a powder diet and analyzed the fucoxanthin metabolite contents in the liver, small intestine and serum of diabetic/obese KK-Ay mice. After 4 weeks of feeding with the experimental diets, the serum fucoxanthinol concentrations of the mice fed 0.2% SO and 0.5% monocaprin were higher than those of the 0.2% SO-fed mice. Furthermore, fucoxanthinol accumulation in the liver and small intestine tended to increase in a combination diet of 0.2% SO and 0.125–0.5% monocaprin compared with a diet of 0.2% SO alone, although amarouciaxanthin A accumulation was not different among the 0.2% SO-fed groups. These results suggest that a combination of monocaprin with fucoxanthin-containing SO is an effective treatment for improving the bioavailability of fucoxanthin.
Application of short‐time Fourier transform for harmonic‐based protection of meshed VSC‐MTDC grids

This work studies the application of short-time Fourier transform (STFT) to extract current harmonics of various fault types to design a protection method for meshed multi-terminal voltage source converter-high-voltage direct current (VSC-HVDC-MTDC) grids. The frequency spectrum of fault current harmonics is used to detect internal and external faults, the faulty pole and fault type. The method does not need the implementation of series inductance on the sides of the DC lines and it is also effective for lines combining overhead lines and cables. The window function and hop size play the primary role in STFT, which are investigated in a sensitivity analysis. A modified version of CIGRE meshed DC grid system is simulated in PSCAD in order to show the robustness of the method, and further signal processing analysis is done in MATLAB. The results show the accurate detection and discrimination between faulty sections using the proposed harmonic-based method and how important the STFT parameters are in order to have a robust protection algorithm.
Photovoltaic Integrated Hybrid Microgrid Structured Electric Vehicle Charging Station and Its Energy Management Approach

A hybrid microgrid-powered charging station reduces transmission losses with better power flow control in the modern power system. However, the uncoordinated charging of battery electric vehicles (BEVs) with the hybrid microgrid results in ineffective utilization of the renewable energy sources connected to the charging station. Furthermore, planned development of upcoming charging stations includes a multiport charging facility, which will cause overloading of the utility grid. The paper analyzes the following technical issues: (1) the energy management strategy and converter control of multiport BEV charging from a photovoltaic (PV) source and its effective utilization; (2) maintenance of the DC bus voltage irrespective of the utility grid overloading, which is caused by either local load or the meagerness of PV power through its energy storage unit (ESU). In addition, the charge controller provides closed loop charging through constant current and voltage, and this reduces the charging time. The aim of an energy management strategy is to minimize the usage of utility grid power and store PV power when the vehicle is not connected for charging. The proposed energy management strategy (EMS) was modeled and simulated using MATLAB/Simulink, and its different modes of operation were verified. A laboratory-scale experimental prototype was also developed, and the performance of the proposed charging station was investigated.
Correlation between BMI and Oral Health Status (DMFT, PI, mSBI, and Salivary 1,5-AG) among the Pediatric Population in Saudi Arabia: A Clinico-Biochemical Study

The study aimed to investigate the association of varying body mass index (BMI) with oral health status among children aged 5–14 years and correlate the concentration of salivary levels of 1,5-AG with varying BMI, dental caries, and periodontal disease. This cross-sectional study was conducted on subjects aged 5 to 14 years. The children were recruited from the Pediatric Dental Clinic, College of Dentistry, Majmaah University, by convenient sampling method. Sociodemographic details and clinical parameters, including body mass index (BMI), DMFT/def (deciduous decayed tooth (d), deciduous extracted tooth (e), deciduous filled tooth (f), permanent tooth decayed (D), permanent missing tooth (M), and permanent filled tooth (F)), plaque index (PI), and modified sulcular bleeding index (mSBI), were evaluated. Salivary 1,5-anhydroglucitol (1,5-AG) was analyzed using an enzyme-linked immunosorbent assay (ELISA) for all the subjects. Statistical analyses performed using SPSS v. 27 (IBM Statistics, Chicago, IL, USA) and the Kruskal–Wallis and chi-square tests were used for comparisons. The Spearman rank correlation coefficient was used to examine the association between the study subjects’ independent variables, BMI, and caries activity. The mean def score, PI, and mSBI scores were higher in obese children. PI score, mSBI score, and salivary concentrations of 1,5-AG between the BMI categories were statistically significant (p < 0.001). The study emphasizes promoting preventive oral health regimes, health awareness campaigns, and nutritional educational programs among the pediatric population.
Burnout and its correlation with workplace bullying in Portuguese nurses

ABSTRACT The present work aims at describing the psychometric characteristics of the assessment instruments MBI-HSS (Maslach Burnout Inventory—Human Services Survey) and NAQ-R (Negative Act Questionnaire—Revised). In addition, it seeks to evaluate burnout prevalence, and its correlation with bullying, among nurses working in Portuguese health institutions. The study presents a descriptive, correlational and cross-sectional nature. A questionnaire elaborated in digital format, was employed as data collection instrument. It included the social-demographic and professional components, both assessed using the MBI-HSS and NAQ-R scales. The total sample comprised 2015 nurses. It was found that 2.68% of the nurses were already experiencing burnout, while 23.37% were in high risk, and 42.68% were in medium risk, of developing burnout. Furthermore, those who had suffered workplace bullying reported having greater emotional exhaustion and depersonalization. The chosen evaluation instruments exhibited good reliability and validity index. Nurses who suffered workplace bullying presented an enhanced risk of developing burnout. In this scope, it is fundamental the nurse managers’ involvement in the prevention of harmful behaviors at work, as well as in the promotion of interpersonal relationships based on respect and cooperation. Workplace bullying is considered a harmful phenomenon, responsible for numerous consequences that affect workers and organizations alike. Burnout is one of the reported adversities. This phenomenon has negative effects on the nurses mental and physical health and deterioration of patient care. Prevention increase the number of healthy nurses and the quality of patient care.
Evaluation of Nutritional Components, Phenolic Composition, and Antioxidant Capacity of Highland Barley with Different Grain Colors on the Qinghai Tibet Plateau

The nutritional composition, polyphenol and anthocyanin composition, and antioxidant capacity of 52 colored highland barley were evaluated. The results showed that the protein content of highland barley in the black group was the highest, the total starch and fat contents in the blue group were the highest, the amylose content in the purple group was quite high, the fiber content in the yellow group was quite high, and the β-glucan content of the dark highland barley (purple, blue and black) was quite high. The polyphenol content and its antioxidant capacity in the black group were the highest, while the anthocyanin content and its antioxidant capacity in the purple highland barley were the highest. Ten types of monomeric phenolic substances were the main contributors to DPPH, ABTS, and FRAP antioxidant capacity. All varieties could be divided into four categories according to nutrition or function. The grain color could not be used as an absolute index to evaluate the quality of highland barley, and the important influence of variety on the quality of highland barley also needed to be considered. In actual production, suitable raw materials must be selected according to the processing purpose and variety characteristics of highland barley.
Numerical Analysis of a Full-Scale Thermophilic Biological System and Investigation of Nitrate and Ammonia Fates

Thermophilic biological processes proved to be effective in aqueous waste (AW) and high-strength wastewater treatment. In this work, the monitoring of a full-scale aerobic thermophilic biological plant treating various high-strength AW in continuous mode is reported. This paper aims to: (i) provide models to help the AW utility manager in predicting the load of fed pollutants and performances, and (ii) fully investigate nitrogen transformations in biological reactor. Based on the results, the thermophilic sludge in the studied plant was able to degrade Chemical Oxygen Demand (COD) and remove nitrate nitrogen with very high efficiency (79.3% and 97.1, respectively). The monitoring was conducted following a statistical approach and searched for the possible correlations between the input parameters and the efficiency of removal of the plant. Moreover, a multivariate linear regression was carried out highlighting that the yield value of the removal of COD and nitrogen forms, apart from ammonia, was well explained (R2 = 0.9) by the linear regression against the other monitored parameters. As far as nitrification is concerned, there was, on the one hand, an increase in ammonium ions due to the hydrolysis of the organic substance that occurs in the reactor, and on the other hand, a stripping of the same ammoniacal nitrogen in the form of NH3. While nitrates were effectively removed, according to fluorescent in situ hybridization tests, sludge proved to be formed by minute flocs, where bacteria responsible for the oxidation of ammonium and nitrite seem to be unable to grow.
An Ecological Investigation of Kindergarten-Oriented Educational Practice during the Initial COVID-19 Class Suspension in China

ABSTRACT Research Findings: Given that kindergartens are essential in sustaining children’s education during the COVID-19 lockdown, this study investigates kindergarten-oriented educational practice during the initial class suspension (February–June 2020) in China. Articles published via twenty Chinese kindergartens’ WeChat official subscription accounts during this period and relevant policy documents were collected and analyzed. This study found that during the class suspension, China’s kindergartens were able to continue providing education by adding the topic of COVID-19 to the curriculum, remaining focused on subject-related learning, utilizing digital technologies as a communication platform, and assigning different roles to parents to support children’s learning at home. However, activities prescribed by teachers and kindergartens were generally teacher-directed and structured, which led to the marginalization of children’s voices and play. Practice or Policy: As kindergarten prescribed teaching and learning activities misalign with the “broad definition of learning” encouraged by macro-level documents, the policy-practice gap implies that: i) teachers could explore how digital technologies could be combined with child-centered activities in online learning; ii) parents need supports for extending children’s learning and play at home; iii) policy-makers should provide more detailed guidelines and practical suggestions for teachers to support learning, including the post-COVID period.
Normal and abnormal development of the aortic valve and ascending aortic wall: a comprehensive overview of the embryology and pathology of the bicuspid aortic valve

A bicuspid aortic valve (BAV) is the most prevalent congenital cardiac anomaly, in which the valve has only two leaflets, instead of the normal three. Patients with a BAV have an increased risk of aneurysm formation and the development of an aortic dissection. Vascular smooth muscle cells in both the non- and dilated aortic wall are characterized by a maturation defect in all BAV patients, as compared to patients with a tricuspid aortic valve, which can contribute to inherent developmental susceptibility. Besides structural abnormalities of the vascular wall, a turbulent blood flow, caused by bicuspid valve geometry, could expedite the pathological process in the aortic wall, leading to aortopathy. Although the risk for aortopathy is significant, not all BAV patients experience (acute) aortic complications in their lifespan, highlighting the complexity of the pathogenetic process. Recent studies have focused on the embryonic development of semilunar valves and the ascending aortic wall. Their findings highlight that a defect in the embryogenesis could not only explain the development of a malformed aortic valve but also the increased risk for ascending aorta and arch pathology. This review presents an overview of the normal and abnormal development of the aortic valve and the aortic wall: a common defect in early embryogenesis causes the development of a BAV and associated aortopathy.
A Prospective Trial of the Microneedle Fractional Radiofrequency System Application in the Treatment of Infraorbital Dark Circles

Background Infraorbital dark circles (IDC) are commonly consulted in aesthetic practice. There is not yet a multifactorial approach to facilitating their treatment. Objective To investigate the safety and efficacy of the microneedle fractional radiofrequency (MRF) system for the treatment of IDC. Methods A prospective, split-face, evaluator-blind clinical trial was conducted to study the change in the overall appearance, color, and wrinkles in 21 female patients with mixed type IDC before and after MFR treatment. Results Both patients and independent evaluators found significant improvement on the global aesthetic scales after the MFR treatment, especially on periorbital wrinkles (p=0.031). Trends in decreased melanin density in the IDC area were found, but no statistical differences were established. No side effects were observed. Conclusion MFR is a safe and effective modality for improving mixed type IDC by correcting the structural factors.
Assessment of Physical, Mechanical, Biopharmaceutical Properties of Emulgels and Bigel Containing Ciclopirox Olamine

Emulsions are thermodynamically unstable systems and it is difficult to produce biphasic formulations with large amounts of oil. The aim of our study was to prepare biphasic formulations containing 1% ciclopirox olamine and to determine the influence of the method of oil incorporation (without and with emulsifier and gelifier) on the physical (pH, particle size, rheological properties), mechanical, and biopharmaceutical properties of the formulations. It was found that the use of a poloxamer 407 gel as the hydrophase could result in a stable formulation when an oil with (EPG) or without an emulsifier (APG) or oleogel (OPG) was used as the oily phase. The results of the studies showed that the addition of an emulsifier (polysorbate 80) led to a decrease in the sol-gel temperature, a slower release of ciclopirox olamine, and a higher stability in the freeze–thaw test. However, regardless of the way the oil is incorporated, the particles are distributed in the same range and the antifungal activity against T. rubrum is the same. It is possible to create a biphasic formulation with a large amount of oil and poloxamer gel, but for greater stability, it is recommended to include an emulsifier in the composition.
Evaluation of solubilizing potential of functional poly(jasmine lactone) micelles for hydrophobic drugs: A comparison with commercially available polymers

Abstract Achieving high solubilization capacity with the aid of polymeric micelles (PM) is still a major challenge. To address this shortcoming, novel poly(jasmine lactone) (PJL)-based PM were developed and compared with Soluplus® and poly(lactide) copolymer. The presence of “ene” groups on PJL’s backbone offers a unique opportunity to insert functional groups. We introduced -COOH and phenyl groups onto the PJL copolymer and observed a ∼334-fold increment in aqueous solubility of clotrimazole with -COOH-terminated PJL copolymer compared to Soluplus. We thus successfully demonstrated that the presence of appropriate free functional groups on the polymer chain can facilitate the solubilization potential of PM. Graphical Abstract
The optimal oral body temperature cutoff and other factors predictive of sepsis diagnosis in elderly patients

INTRODUCTION: The aim of this study was to identify the optimal oral temperature cut-off value and other factors predictive of sepsis in elderly patients presenting to emergency department. METHODS: A hospital-based retrospective study was performed on all elderly patients who presented to the Adult Emergency Department at King Abdulaziz Medical City in Riyadh (January to December 31, 2018). RESULTS: Of total of 13,856 patients, 2170 (15.7%) were diagnosed with sepsis. The associated area under the curve estimate was 0.73, 95% confidence interval (CI) 0.72–0.74. Body temperature ≥37.3 was found as optimal cut-point with sensitivity = 50.97% and specificity = 87.22% and 82.39% of patients with sepsis will be correctly classified using this cut-off. An increase of 1° in body temperature was associated with an odds ratio of 9.95 (95% CI 8.95–11.06, P < 0.0001). Those aged ≥100 years having 11.12 (95% CI 2.29–20.88, P < 0.0001) times the likelihood for sepsis diagnosis compared with those aged 60–69 years. People admitted in weather such as winter, spring, or autumn were more likely to develop sepsis than people admitted in summer. CONCLUSION: The risk factors of sepsis such as age, temperature, and seasonal variation inform important evidence-based decisions. The hospitals dealing with sepsis patients should assess older patients for other severe illnesses or co-morbid that might lead to sepsis if left untreated. Therefore, older patients need to be prioritized over younger patients. The body temperature of patients admitted to hospitals needs to be monitored critically and it is important to consider seasonal fluctuations while managing cases of sepsis and allocating resources. Our findings suggest that clinicians should explore the possibility of sepsis in elderly patients admitted to emergency units with oral temperature ≥37.3°C. Risk factors for sepsis reported in this study could inform evidence-based decisions.
Extraordinary mullet growth through direct injection of foreign DNA

The present study aims to produce a genetically modified grey mullet, Mugil cephalus , with accelerated growth through direct injection of foreign DNA isolated from the liver of shark ( Squalus acanthias L.) or African catfish ( Clarias gariepinus ) into muscles of fingerlings fish at the dose of 40 μg/fish. The results show a significant (P≤0.05) improvement in most of the growth performance and body composition parameters of genetically modified grey mullet fingerlings injected with shark DNA compared to both genetically modified grey mullet injected with catfish DNA and the control fish, while the results of feed conversion ratio (FCR) and protein efficiency ratio (PER) indicate that fish injected with shark DNA or catfish DNA had significant (P≤0.05) superiority compared to their control. The results of the random amplified polymorphic DNA (RAPD) fingerprinting show highly genetic polymorphic percentage among grey mullet that received foreign DNA and their control using different random primers. This may be due to some fragments of foreign DNA randomly integrated into grey mullet genome. Therefore, the result indicates a possible easy and rapid way for improving fish characteristics.
