Published: February 2022

Abstract
BackgroundDuring the COVID-19 pandemic, the restrictions brought about by new normal protocols have obstructed Thai village health volunteers (VHVs) from carrying out regular duties and training. However, they seem to have found ways to learn and fulfil tasks in connection with COVID-19 prevention. The research examines their learning methods and the employment of collective power, a cultural asset found in Thai communities, to overcome working challenges. MethodQualitative data was collected from 30 VHVs working in ten communities from ten provinces across Thailand during the third wave of the pandemic. Semi-structured interviews and small focus groups were employed as data collection techniques. The themes and patterns under two main concepts – self-directed learning and collective power - were identified and analyzed. Results The VHVs’ self and selves-directed learning approaches were discovered. Not only did they gain COVID-19 related information from mass media and online platforms, but they also took initiatives to learn unfamiliar technologies which became important working tools in the context of the situation. While such learning methods highlight their autonomous learning attributes involving individuality or “self” learning concepts, the way they incorporated a collaborative learning method, reflects “selves” learning practices. The VHVs also utilized collective power - both in-group and inter-group power – through different networking systems. The main factors underpinning the collective power were kinship and kinship-like relationships among the VHVs and their community fellows. Their strong determination in working to help others - “doing good deeds” – helped to drive their self-learning and called for collective actions. ConclusionEven though the abruptness of the outbreak coupled with the lack of knowledge about COVID-19 left the VHVs unprepared for the task, the VHVs were able to adapt themselves and employ both autonomous and group learning methods. Unique Thai cultural characteristics (i.e., collective power, networking, and kinship systems) have become social capital that helps them to overcome working and learning difficulties. This study thus illustrates the possible intertwinement of collectivistic and individualistic values found in the process of self and selves-directed learning practices, and the implication of collective power as a cultural force in the field of community health promotion.

Abstract
Background: Loropetalum chinense var. rubrum is a typical colorful ornamental and medicinal plant. However, the coloration information and potential colorful molecular mechanisms of its leaves remain unclear. We analyzed structural and regulatory genes for flavonoid metabolites and anthocyanin biosynthesis in 3 kinds color of leaves（PL, pink leaves; ML, middle color leaves; GL, green leaves) of L. chinense var. rubrum.Results: Metabolic detection to the samples showed that there were significant differences in the metabolites accumulated in different color leaves. Meanwhile, transcriptome indicated that DFR, ANR and UFGT genes in L. chinense var. rubrum might be one of the reasons for the accumulation of anthocyanin in ML and GL. We also found that several key members of the MYB, BHLH, and WD40 gene families played important roles in regulating the accumulation of flavonoids in plants, which were considered to be the main drivers of transcriptional changes in different colors of L. chinense var. rubrum leaves. Our findings provided a comprehensive data set for the metabolism and transcription of L. chinense var. rubrum as well as candidate structures and transcription factors information related to leaf pigmentation.Conclusions: The conclusion would provide useful information for elucidating the formation of leaf color and anthocyanin accumulation in L. chinense var. rubrum，which could also explain the color variation in its leaves.

Published: February 2022

Abstract:
Aortic cause of acute chest pain or abdominal pain can be easily overlooked. Unceasing
wariness is required for timely diagnosis and prompt treatment. In such cases, cross-sectional imaging
can detect the type of aortic involvement, its site, extent, complications, and could help clinicians decide
on a management method and prognosticate the condition. This pictorial illustration represents a
spectrum of life-threatening conditions involving the aorta in a non-traumatic setting.
M-estimation based Robust Approach for Hybrid Dynamic State Estimation in Power Systems
Authors: Kundu Shubhrajyoti , Alam Mehebub , Saha Roy Biman Kumar , Thakur Siddhartha Sankar 
Published: February 2022

Background:
The state estimation (SE) process in power systems estimates bus voltage
magnitude and phase angles vital for operating the system securely and reliably. The power systems
state estimation problem has been extensively solved through a weighted least squares (WLS) based
static approach that fails to track the system dynamics. Furthermore, those approaches are not inherently
robust against outliers, yielding a separate bad data processing (BDP) technique. Popular Dynamic
state estimation (DSE) schemes which mainly employ nonlinear Kalman filters like Extended
Kalman Filter (EKF) and Unscented Kalman Filter (UKF), also suffer from providing a reasonable estimation
of states in the presence of bad data. Although several generalized maximum (GM) likelihood-
based DSE approaches are robust against outliers, they are mainly based on nonlinear Kalman
filters, which yield an iterative process. Therefore, this article focuses on developing a robust DSE
approach that gives a good estimation of states against outliers in a single iteration.

Objective:
This article aims to propose a robust hybrid non-iterative DSE approach that gives robust
SE results in the presence of bad data.

Methods:
The proposed novel robust hybrid DSE (NRHDSE) approach combines the robust Mestimation
with the original novel hybrid DSE (NHDSE) approach. The proposed scheme implements
a suitable linear relationship between integrated hybrid measurements and complex states. The proposed
method uses a linear measurement model and thus employs an optimal linear Kalman filter to
correct or estimate states.

Results:
The efficacy of the proposed approach has been demonstrated by applying it on IEEE 57, 118
bus test systems and one more extensive 246 Indian utility bus system, namely, Northern Regional
Power Grid (NRPG), and after that comparing it with the original NHDSE, and DSE methods based
on traditional EKF and M-estimation based robust version of EKF (REKF). The simulation result
demonstrates the superiority of the proposed approach.

Conclusions:
Obtained results clearly show the superiority of the proposed approach.
Comparison of the Erectile Dysfunction Drugs Sildenafil and Tadalafil Using Patient Medication Reviews: Topic Modeling Study
Authors: Kim Maryanne , Noh Youran , Yamada Akihiko , Hong Song Hee 
Published: February 2022

Background
Topic modeling of patient medication reviews of erectile dysfunction (ED) drugs can help identify patient preferences regarding ED treatment options. The identification of a set of topics important to the patient from social network service drug reviews would inform the design of patient-centered medication counseling.

Objective
This study aimed to (1) identify the distinctive topics from patient medication reviews unique to tadalafil versus sildenafil; (2) determine if the primary topics are distributed differently for each drug and for each patient characteristic (age and time on ED drug therapy); and (3) test if the primary topics affect satisfaction with ED drug therapy controlling for patient characteristics.

Methods
Data were collected from the patient medication reviews of sildenafil and tadalafil posted on WebMD and Ask a Patient. The latent Dirichlet allocation method of natural language processing was used to identify 5 distinctive topics from the patient medication reviews on each drug. Analysis of variance and a 2-sample t test were conducted to compare the topic distribution and assess whether patient satisfaction varies with the primary topics, age, and time on medication for each ED drug. Statistical significance was tested at an alpha of .05.

Results
The patient medication reviews of sildenafil (N=463) had 2 topics on treatment benefit and 1 each on medication safety, marketing claim, and treatment comparison, while the patient medication reviews of tadalafil (N=919) had 2 topics on medication safety and 1 each on the remaining subjects. Sildenafil’s reviewers quite frequently (94/463, 20.4%) mentioned erection sustainability as their primary topic, whereas tadalafil’s reviewers were more concerned about severe medication safety. Those who mentioned erection sustainability as their primary topic were quite satisfied with their treatment as opposed to those who mentioned severe medication safety as their primary topic (score 3.85 vs 2.44). The discovered topics reflected the marketing claims of blue magic and amber romance for sildenafil and tadalafil, respectively. The topic of blue magic was preferred among younger patients, while the topic of amber romance was preferred among older patients. The topic alternative choices, which appeared for both the ED drugs, reflected patient interest in the comparative effectiveness and price outside the drug labeling information.

Conclusions
The patient medication reviews of ED drugs reflect patient preferences regarding drug labeling information, marketing claims, and alternative treatment choices. The patient preferences concerning ED treatment attributes inform the design of patient-centered communication for improved ED drug therapy.

Background
Existing modes of collecting self-reported 24-hour movement information from children, including digital assessments, have not been demonstrated to be of acceptable validity when compared to objective measurements. My E-Diary for Activities and Lifestyle (MEDAL) is an interactive web-based diary developed to collect time-use information from children aged 10 years and older.

Objective
This study evaluated the validity of MEDAL for assessing children’s movement behaviors by comparing self-reported and accelerometer-measured time spent in movement behavior among children in Singapore aged 10-11 years.

Methods
Funding for this study was obtained in October 2017, and data were collected between April and August 2020. Participants recorded their daily activities using MEDAL over 2 specified weekdays and 2 weekend days and wore an Actigraph accelerometer on their nondominant wrist throughout the study to objectively assess movement behaviors. Spearman correlation coefficient and intraclass correlation coefficient (ICC) were used to compare the accelerometer measurements and self-reports for each movement behavior. Bland-Altman plots were generated to investigate trends of bias in the self-reports.

Results
Among the participants aged 10-11 years (29/49, 59% boys), we observed that children reported lower light physical activity (LPA) and higher moderate-to-vigorous physical activity (MVPA), inactivity, and night sleep than that measured by the accelerometer. There was a moderate-to-strong correlation between self-reported and accelerometer-measured MVPA (r=0.37; 95% CI 0.20-0.54), inactivity (r=0.36; 95% CI 0.18-0.54), and night sleep (r=0.58; 95% CI 0.43-0.74); the correlation for LPA was poor (r=0.19; 95% CI 0.02-0.36). Agreement was poor for all behaviors (MVPA: ICC=0.24, 95% CI 0.07-0.40; LPA: ICC=0.19, 95% CI 0.01-0.36; inactivity: ICC=0.29, 95% CI 0.11-0.44; night sleep: ICC=0.45, 95% CI 0.29-0.58). There was stronger correlation and agreement on weekdays for inactivity and night sleep; conversely, there was stronger correlation and agreement for MVPA and LPA on weekend days. Finally, based on Bland-Altman plots, we observed that with increasing MVPA, children tended to report higher MVPA than that measured by the accelerometer. There were no clear trends for the other behaviors.

Conclusions
MEDAL may be used to assess the movement behaviors of children. Based on self-reports, the children are able to estimate their time spent in MVPA, inactivity, and night sleep although actual time spent in these behaviors may differ from accelerometer-derived estimates; self-reported LPA warrant cautious interpretation. Observable differences in reporting accuracy exist between weekdays and weekend days.

SUMMARY

Objective
To evaluate the microshear bond strength (mSBS) of 10 universal adhesive systems applied on five different CAD/CAM restorative materials, immediately and after thermal aging.

Methods and Materials
Five CAD/CAM materials were selected: 1) feldspathic glass ceramic (FeCe); 2) pre-polymerized reinforced resin composite (ReRC); 3) leucite-reinforced glass ceramic (LeGC); 4) lithium disilicate (LiDi); and 5) yttrium-stabilized zirconium dioxide (ZiDi). For each material, 15 blocks were cut into four rectangular sections (6 × 6 × 6 mm; n=60 per group) and processed as recommended by the respective manufacturer. For each indirect material, the following adhesive systems were applied according to the respective manufacturer’s instructions: 1) AdheSE Universal [ADU]; 2) All-Bond Universal [ABU]; 3) Ambar Universal [AMB]; 4) Clearfil Universal Bond [CFU]; 5) Futurabond U [FBU]; 6) One Coat 7 Universal [OCU]; 7) Peak Universal Bond [PUB]; 8) Prime&Bond Elect [PBE]; 9) Scotchbond Universal Adhesive [SBU]; 10) Xeno Select [XEN, negative control]. After the application of the adhesive system, cylinder-shaped transparent matrices were filled with a dual-curing resin cement (NX3) and light cured. Specimens were tested in shear mode at 1.0 mm/min (mSBS), after 24 hours and 10,000 thermal cycles (TC). All data were submitted to statistical analysis (α=0.05).

Results
For FeCe, there was no significant decrease in mean mSBS for AMB, FBU, and SBU after TC when compared at 24 hours. For ReRC, AMB and SBU showed higher mean mSBS when compared to CFU and XEN, after 24 hours and TC. For LiDi, FBU and OCU showed higher mean mSBS when compared to CFU and XEN, after 24 hours and TC. For LeGC, AMB and PUB showed higher mean mSBS when compared to XEN, after 24 hours and TC. For ZiDi, OCU and SBU showed higher mean mSBS when compared to XEN, after 24 hours and TC. In addition, PBE and XEN showed the lowest mean mSBS after TC with higher percentage of bond strength reduction.

Conclusions
The mean mSBS among the different universal adhesives varied widely for each CAD/CAM material used. In addition, most universal adhesives underwent a statistically significant bond strength reduction after TC.

Weather Prediction is a field of meteorology that is created by collecting dynamic data related to the current state of the weather such as temperature, humidity, rainfall, wind. In this paper, we designed a system using a classification method by k-Nearest Neighbors algorithm for predict whether through previous data to determine the expected temperature and humidity the prediction results were compared with real results, the comparison was good and acceptable.
Plunging Ranula with the Oral Counterpart in A 6-Year-Old Boy: A Case Report
Authors: Mabel Etetafia O. 
Published: February 2022

A ranula is a collection of salivary fluid on the floor of the oral cavity due to obstruction of the salivary duct or as a result of extravasation of the saliva. A plunging ranula results from extension of salivary fluid into the submental or submandibular spaces through the posterior aspect of the mylohyoid muscle or through a dehiscence on the muscle. It could also extend to multiple spaces mimicking cystic lesions of the neck region. Ranula mostly involve the sublingual gland. The prevalence of ranula is 0.2% per 1000 patients. There are usually no symptoms except when large which then causes discomfort in mastication and swallowing. Various treatment options have been advocated but the most commonly adopted one is drainage of the collection in addition to excision of the affected gland. The case presented is an oral and plunging ranula found in a 6-year-old boy of eight weeks duration. Presenting symptoms were painless swelling underneath and beside the tongue in addition to swelling at the submental region. There was occasional discomfort during mastication and swallowing. Ultrasound scan showed a 40mm by 30 mm cystic mass. The ranula was excised through the intraoral route together with excision of the implicated left sublingual gland. Post-operative reviews show no recurrence.
Conclusion: Oral and plunging ranula do occur in children. Transoral approach to the drainage of the salivary collection with the excision of the affected sublingual gland is appropriate in the management of this condition.

The Sava River based its fluvial architecture compromised its upper- and lower courses. The Sava River upper course starts at Radovljica and continues downstream till Krško while from Krško till Belgrade is the Sava lower course. The Sava upper course is positioned in the mountain valley and characterized with headwaters. The Sava lower course positioned in the lowland area of the Pannonian Plain.
The Sava Plain (Posavina) is a physico-geographical region, encompass the lowermost, almost flat surface of plain segments of the Sava valley, lower plain segments of its tributaries and adjacent eolian flat landforms. The Sava Plain surface geology composed of Holocene fluvial, as well as Pleistocene alluvial and eolian sediments. According to the Holocene fluvial architecture of the Sava river three significant parts can be defined as the Krško-Samobor Plain, the Upper- and the Lower Sava Plain. The Upper Sava valley represents the Krško-Samobor Basin from Krško downstream till the Podsused Gate. The Upper Sava Plain (Gornja posavina) covers the Sava plain in between Podsused Gate downstream to the Slavonski- and Bosanski Brod (or the Brod Gate). The Lower Sava Plain (Donja posavina) ascends from Brod Gate downstream till the mouth of the Sava to the Danube in Belgrade.
The Krško-Podsused Plain and the Upper Sava Plain channel planform type characterized with the gentle meandering river architecture its area composed of Holocene fluvial sediments, while the Lower Sava Plain with meandering river architecture of Pleistocene fluvial and eolian sediments and Holocene fluvial.
