Comparison of machine learning models for flood forecasting in the Mahanadi River Basin, India
Authors: Sharma Sanjay , Kumari Sangeeta
Published: March 2024

Developing accurate flood forecasting models is necessary for flood control, water resources and management in the Mahanadi River Basin. In this study, convolutional neural network (CNN) is integrated with random forest (RF) and support vector regression (SVR) for making a hybrid model (CNN–RF and CNN–SVR) where CNN is used as feature extraction technique while RF and SVR are used as forecasting models. These hybrid models are compared with RF, SVR, and artificial neural network (ANN). The influence of training–testing data division on the performance of hybrid models has been tested. Hyperparameter sensitivity analyses are performed for forecasting models to select the best value of hyperparameters and to exclude the nonsensitive hyperparameters. Two hydrological stations (Kantamal and Kesinga) are selected as case studies. Results indicated that CNN–RF model performs better than other models for both stations. In addition, it is found that CNN has improved the accuracy of RF and SVR models for flood forecasting. The results of the training–testing division show that both models’ performance is better at 50–50% data division. Validation results show that both models are not overfitting or underfitting. Results demonstrate that CNN–RF model can be used as a potential model for flood forecasting in river basins.

Published: March 2024

The decision-making process of wind–photovoltaic–hydropower systems involves knowledge from many fields. Influenced by the knowledge level of the decision-maker and the attribute information of the scheme set, there exists a certain uncertainty in the indicator weights. In view of this, this paper proposes a stochastic multi-criteria decision-making framework for scheduling of wind–photovoltaic–hydropower systems, which overcomes the difficulty of uncertainty in indicator weights or even completely unknown information about indicator weights at the time of decision-making. The Stochastic Multi-criteria Acceptability Analysis (SMAA) theory and the VIKOR model are introduced, and the proposed SMAA–VIKOR model makes the indicator weight space explicit. The study shows that the proposed SMAA–VIKOR model can overcome the obstacle of decision-makers’ lack of information on indicator weights. The ranking acceptability indicators calculated by the model show a more obvious trend of advantages and disadvantages, which gives full confidence to the decision-making group to formulate a plan to be implemented. It breaks through the bottleneck of group decision-making, which is difficult to make effective decisions due to the condition of incomplete information, and enriches the library of stochastic multi-criteria decision-making methods for the scientific formulation of scheduling schemes of wind–photovoltaic–hydropower systems under uncertainty conditions.

Authors: COSTA JOÃO EDUARDO AZEVEDO DA
Published: March 2024

Este artigo do tipo relato de experiência, descreve aspectos da práxis docente no ensino de Geografia na Escola Municipal de Ensino Fundamental e Médio Raul de Medeiros Dantas em São José do Seridó – RN. A experiência ocorreu durante o ano letivo de 2018, na turma do 6º ano III. Esta turma composta por alunos repetentes e fora de faixa, também recebia alunos transferidos de outras instituições de ensino. Logo, a indisciplina e falta de interesse desse grupo de alunos terminou por caracterizar a classe como “turma problema”. Na busca por soluções, em cooperação com a equipe pedagógica da escola, foi possível através das temáticas presentes na geografia escolar, criar estratégias didático-pedagógicas para estimular paulatinamente a participação destes alunos nas atividades. Na sala de aula utilizamos estratégias como pesquisas na internet, interpretações de textos, músicas, vídeos e imagens, caça palavras, confecções de cartazes e maquetes. Participamos de eventos escolares e realizamos aulas de campo dentro e fora do município. A avaliação se deu através de provas escritas bimestrais, atividades semanais e participação em eventos. Consideramos o compromisso e pontualidade na entrega das atividades. Trabalhar com o 6º ano III, foi uma experiência única e enriquecedora para alunos, professores e equipe pedagógica. Considerando as fragilidades e potencialidades do público alvo, o nosso objetivo foi oferecer aos alunos a possibilidade de conhecimento e reconhecimento do lugar de vivências individuais e coletivas. Ao final, os resultados foram surpreendentemente positivos. Como aporte teórico citamos: Carlos (2007), Cavalcanti (2015), Demo (2002), Dozena (2008) e Kaercher (1996).
Looking at the Golden Ratio from the Blood Pressure Perspective: Assessing the Hypertensive Patients and Normotensive Subjects
Authors: Atmaca Hasan , Cuglan Bilal , Karagöz Zuhal Karaca , Yalta Kenan , Yetkin Ertan
Published: March 2024

Background:

The representatives of mathematical concepts and indices allied to the
Golden Ratio (GR) have been shown in the human body in superimposed human hands, phalangeal
lengths of the digits, human ears, and the cardiovascular system. Recently, it has been demonstrated
that the systolic blood pressure (SBP) to diastolic blood pressure (DBP) ratio measured
by ambulatory blood pressure monitoring (ABPM) is close to GR. Accordingly, we aimed
to evaluate the ratios between the SBP, DBP, and PP in normotensive and hypertensive patients
who were on medical treatment or not, to assess the existence of golden proportions in 24-hour ambulatory
blood pressure monitoring results.

Material and Method:

Five hundred and twenty-nine patients who underwent ABPM were retrospectively
enrolled in the study population. The ABPM was programmed to measure blood pressure
every 30 min during the daytime and 60 min night time. Based on the ABPM results, patients
were classified as hypertensive (SBP/DBP≥130/80 mmHg) and normotensive (SBP/DBP<130/80
mmHg), depending on ESC/ESH 2018 guidelines. They were also divided into two subgroups:
medicated and nonmedicated. Systolic to diastolic blood pressure ratio (SBP/DBP) and diastolic
blood pressure to pulse pressure (DBP/PP) were calculated in the usual fashion in all study populations
and subgroups.

Results:

After the exclusion of 133 patients who did not fulfill the inclusion criteria, 396 patients
were included in the statistical analysis. Mean SBP/DBP ratios were 1.66±0.15 in all the study
population, 1.63±0.11 in normotensive without medication, 1.66±0.13 in normotensive with medications,
1.62±0.15 in hypertensive without medication, and 1.76±0.20 with medications.

Conclusion:

We have documented that SBP to DBP ratios of untreated patients, irrespective of
having normal or high blood pressure, run close around the GR. However, SBP to DBP ratios of
patients having antihypertensive treatment are far from the GR.
Paeoniflorin Alleviates Anxiety and Visceral Hypersensitivity via HPA Axis and
BDNF/TrkB/PLCγ1 Pathway in Maternal Separation-induced IBS-like Rats
Authors: Liang Ruifeng , Ge Wenjing , Song Xianmei , Wang Huisen , Cui Weifeng , Zhang Xuexia , Wei Zheng , Li Gengsheng
Published: March 2024

Background:

Irritable Bowel Syndrome (IBS) is a prevalent gastrointestinal disorder that significantly diminishes the quality of life for affected individuals. The
pathophysiology of IBS remains poorly understood, and available therapeutic options for IBS are limited. The crucial roles of brain-gut interaction,
which is mediated by the Hypothalamic-Pituitary-Adrenocortical (HPA) axis and the autonomic nervous system in IBS, have attracted increasing
attention.

Objective:

The objective of this study was to examine the impact of paeoniflorin (PF) on anxiety and visceral hypersensitivity in maternal separation-induced
IBS-like rats.

Methods:

The IBS-like rat model was established through the implementation of Maternal Separation (MS) and subsequently subjected to various doses of
PF administered via oral gavage for 14 days. Anxiety-like behavior was evaluated using the Open Field Test (OFT) and Elevated Plus Maze (EPM)
test. The assessment of visceral sensitivity involved the utilization of the Abdominal Withdrawal Reflex (AWR) score and electromyographic
(EMG) responses of the external oblique muscle in response to colorectal distention. The levels of adrenocorticotropic hormone (ACTH),
corticosterone (CORT), and corticotrophin-releasing hormone (CRH) were examined by ELISA. Quantitative real-time PCR (qRT-PCR) and
immunofluorescence were employed to detect the expressions of CRH receptors 1 (CRHR1) and 2 (CRHR2). Glucocorticoid receptors (GR),
mineralocorticoid receptor (MR), brain-derived neurotrophic factor (BDNF), tyrosine receptor kinase B (TrkB), and phospholipase C γ1 (PLCγ1)
were examined by Western blot.

Results and Discussion:

The results showed that MS induced anxiety-like behavior and visceral hypersensitivity, while PF treatment attenuated these changes. Furthermore,
the HPA axis hyperactivity in MS rats was attenuated by PF treatment, indicated by reduced serum ACTH, CORT, and CRH levels and recovered
hippocampal CRHR1 and GR expressions. In addition, PF inhibited BDNF/TrkB signaling by downregulating the protein levels of BDNF, TrkB,
and phospho-PLCγ1 in the colon.

Conclusion:

These findings suggest that PF alleviated anxiety and visceral hypersensitivity in MS-induced IBS-like rats, which may be the modulation of HPA
axis activity and BDNF/TrkB/PLCγ1 signaling pathway.

Understanding the molecular interactions in liquids or liquid mixtures of binary or ternary liquids is crucial for various applications. Numerous methods and tools exist to elucidate how atoms interact in such mixtures. This review examines multiple research papers investigating molecular interactions, focusing on the acoustic/ultrasonic technique. This technique employs ultrasonic waves to probe molecular interactions.
Researchers utilized an ultrasonic interferometer to measure ultrasonic wave velocity, liquid den-sity can be determined by using a specific gravity bottle, and employed the Ostwald viscometer for viscosity measurements. Researchers derived several acoustic and thermodynamic parameters by evaluating ultrasonic wave velocity, liquid density, and viscosity.
This comprehensive study dramatically contributes to understanding the molecular interactions within specific samples, with detailed explanations provided for the observed parameters. Ultra-sonic wave propagation influences the medium's physical characteristics; it includes knowledge of the physics of liquid and solution.
How frequency and temperature affect thermo acoustical characteristics has been investigated. The nature of forces between molecules, including hydrogen bonds, charge transfer complexes, hydrogen bond breaking, and complexes, has been deduced from the investigations above.

In this paper, we used the Legendre operational differential matrix method based on the Tau method to find the approximate analytical solutions to the initial value problems and boundary value problems of ordinary differential equations. This method allows the solution of the ordinary differential equation to be computed in the form of an infinite series in which the components can be easily calculated. We introduced a comparison between the approximate solution that we computed and the exact solution of the selected problem, as we found the absolute error. According to the numerical results, the series of solutions we found are accurate and very close to the exact analytical solutions.

Development and Validation of an Interpretable Conformal Predictor to Predict Sepsis Mortality Risk: Retrospective Cohort Study (Preprint)
Authors: Yang Meicheng , Chen Hui , Hu Wenhan , Mischi Massimo , Shan Caifeng , Li Jianqing , Long Xi , Liu Chengyu
Published: March 2024

BACKGROUND

Early and reliable identification of patients with sepsis who are at high risk of mortality is important to improve clinical outcomes. However, 3 major barriers to artificial intelligence (AI) models, including the lack of interpretability, the difficulty in generalizability, and the risk of automation bias, hinder the widespread adoption of AI models for use in clinical practice.

OBJECTIVE

This study aimed to develop and validate (internally and externally) a conformal predictor of sepsis mortality risk in patients who are critically ill, leveraging AI-assisted prediction modeling. The proposed approach enables explaining the model output and assessing its confidence level.

METHODS

We retrospectively extracted data on adult patients with sepsis from a database collected in a teaching hospital at Beth Israel Deaconess Medical Center for model training and internal validation. A large multicenter critical care database from the Philips eICU Research Institute was used for external validation. A total of 103 clinical features were extracted from the first day after admission. We developed an AI model using gradient-boosting machines to predict the mortality risk of sepsis and used Mondrian conformal prediction to estimate the prediction uncertainty. The Shapley additive explanation method was used to explain the model.

RESULTS

A total of 16,746 (80%) patients from Beth Israel Deaconess Medical Center were used to train the model. When tested on the internal validation population of 4187 (20%) patients, the model achieved an area under the receiver operating characteristic curve of 0.858 (95% CI 0.845-0.871), which was reduced to 0.800 (95% CI 0.789-0.811) when externally validated on 10,362 patients from the Philips eICU database. At a specified confidence level of 90% for the internal validation cohort the percentage of error predictions (n=438) out of all predictions (n=4187) was 10.5%, with 1229 (29.4%) predictions requiring clinician review. In contrast, the AI model without conformal prediction made 1449 (34.6%) errors. When externally validated, more predictions (n=4004, 38.6%) were flagged for clinician review due to interdatabase heterogeneity. Nevertheless, the model still produced significantly lower error rates compared to the point predictions by AI (n=1221, 11.8% vs n=4540, 43.8%). The most important predictors identified in this predictive model were Acute Physiology Score III, age, urine output, vasopressors, and pulmonary infection. Clinically relevant risk factors contributing to a single patient were also examined to show how the risk arose.

CONCLUSIONS

By combining model explanation and conformal prediction, AI-based systems can be better translated into medical practice for clinical decision-making.
Use of Digital COVID-19 Exposure Notifications at a Large Gathering: Survey Analysis of Public Health Conference Attendees (Preprint)
Authors: Drover Caitlin M , Elder Adam S , Guthrie Brandon L , Revere Debra , Briggs Nicole L , West Laura M , Higgins Amanda , Lober William B , Karras Bryant T , Baseman Janet G
Published: March 2024

BACKGROUND

WA Notify was Washington State’s smartphone-based COVID-19 digital exposure notification (EN) tool, which was used to help limit the spread of COVID-19 between November 30, 2020, and May 11, 2023. Following the 2022 Washington State Public Health Association Annual Conference, attendees who had WA Notify activated began receiving ENs alerting them to a possible COVID-19 exposure during the conference. A survey was emailed to all conference attendees to measure WA Notify adoption, mechanisms through which attendees received ENs, and self-reported engagement in protective behaviors postexposure.

OBJECTIVE

This study aimed to learn more about the experiences of WA Notify adopters and nonadopters who may have been exposed to COVID-19 at a large group gathering.

METHODS

A web-based survey administered through REDCap (Research Electronic Data Capture; Vanderbilt University) was sent to all attendees of the Washington State Public Health Association conference. Self-reported demographic information and characteristics of respondents were summarized. Regression models were used to estimate relative risks to compare WA Notify adoption and testing behaviors between groups.

RESULTS

Of the 464 total registered attendees who were sent the survey, 205 (44%) responses were received; 201 eligible attendees were included in this analysis. Of those, 149 (74%) respondents reported having WA Notify activated on their phones at the time of the conference. Among respondents with WA Notify activated, 54% (n=77) reported learning of their potential exposure from a WA Notify EN. Respondents who reported that they did not have WA Notify activated and learned of their potential exposure via the event-wide email from conference organizers were 39% less likely to test for COVID-19 compared to respondents with WA Notify activated who learned of their potential exposure from the email (relative risk 0.61, 95% CI 0.40-0.93; P=.02), and this gap was even larger when compared to respondents who learned of their exposure from a WA Notify EN. The most commonly cited reason for not having WA Notify activated was privacy concerns (n=17, 35%), followed by not wanting to receive ENs (n=6, 12%) and being unaware of WA Notify (n=5, 10%).

CONCLUSIONS

Digital EN systems are an important tool to directly and anonymously notify close contacts of potential exposures and provide guidance on the next steps in a timely manner. Given the privacy concerns, there is still a need for increasing transparency surrounding EN technology to increase uptake by the public if this technology were to be used in the future to slow the spread of communicable diseases.
Investigating Nonspecific Effects of the Live-Attenuated Japanese Encephalitis Vaccine on Lower Respiratory Tract Infections in Children Aged 25-35 Months: Retrospective Cohort Study (Preprint)
Authors: Zhan Siyi , Lin Hongbo , Yang Yingying , Chen Tao , Mao Sheng , Fu Chuanxi
Published: March 2024

BACKGROUND

Live attenuated vaccines may be used to prevent nontargeted diseases such as lower respiratory tract infections (LRTIs) due to their nonspecific effects (NSEs).

OBJECTIVE

We aimed to analyze the NSEs of the Japanese encephalitis vaccine on pediatric LRTIs in children aged 25 months to 35 months.

METHODS

A retrospective cohort study was conducted by using a population-based electronic health record database in Zhejiang, China. Enrolled participants were children born from January 1, 2017, to December 31, 2017, and who were inoculated with the live-attenuated Japanese encephalitis vaccine (JE-L) or inactivated Japanese encephalitis vaccine (JE-I) as the most recent vaccine at 24 months of age. The study was carried out between January 1, 2019, and December 31, 2019. All inpatient and outpatient hospital visits for LRTIs among children aged 25 months to 35 months were recorded. The Andersen-Gill model was used to assess the NSEs of JE-L against LRTIs in children and compared with those of JE-I as the most recent vaccine.

RESULTS

A total of 810 children born in 2017 were enrolled, of whom 585 received JE-L (JE-L cohort) and 225 received JE-I (JE-I cohort) as their last vaccine. The JE-L cohort showed a reduced risk of LRTIs (adjusted hazard ratio [aHR] 0.537, 95% CI 0.416-0.693), including pneumonia (aHR 0.501, 95% CI 0.393-0.638) and acute bronchitis (aHR 0.525, 95% CI 0.396-0.698) at 25 months to 35 months of age. The NSEs provided by JE-L were especially pronounced in female children (aHR 0.305, 95% CI 0.198-0.469) and children without chronic diseases (aHR 0.553, 95% CI 0.420-0.729), without siblings (aHR 0.361, 95% CI 0.255-0.511), with more than 30 inpatient and outpatient hospital visits prior to 24 months of age (aHR 0.163, 95% CI 0.091-0.290), or with 5 to 10 inpatient and outpatient hospital visits due to infectious diseases prior to 24 months old (aHR 0.058, 95% CI 0.017-0.202).

CONCLUSIONS

Compared with JE-I, receiving JE-L as the most recent vaccine was associated with lower risk of inpatient and outpatient hospital visits for LRTIs among children aged 25 months to 35 months. The nature of NSEs induced by JE-L should be considered for policymakers and physicians when recommending JE vaccines to those at high risk of infection from the Japanese encephalitis virus.

BACKGROUND

There has been a rapid expansion of digital health care services, making the need for measuring and improving digital health readiness a priority. In response, our study team developed the Mobile-Centered Digital Health Readiness: Health Literacy and Equity Scale (mDiHERS) to measure digital health readiness.

OBJECTIVE

We aim to develop and validate a scale that assesses digital health readiness, encompassing literacy and equity, and to ensure the effective use of mobile-centered digital health services.

METHODS

This study was conducted from October 2021 to October 2022 to develop and validate the mDiHERS. Participants included patients with inflammatory bowel disease, which is a chronic condition requiring continuous management, and experts in medical and nursing informatics. The scale development involved a literature review, focus group interviews, and content validity evaluations. A total of 440 patients with inflammatory bowel disease were recruited for the validation phase, with 403 completing the survey. The scale’s validity and reliability were assessed through exploratory factor analysis and Cronbach α. The scale was translated into English by translators and bilingual and native researchers, ensuring its applicability in diverse settings.

RESULTS

The mDiHERS consists of 36 items across 6 domains, with a 5-point Likert scale for responses. The validation process confirmed the scale’s construct validity, with 4 factors explaining 65.05% of the total variance. The scale’s reliability was established with Cronbach α values ranging from 0.84 to 0.91. The scale’s development considered the technical proficiency necessary for engaging with health mobile apps and devices, reflecting the importance of subjective confidence and objective skills in digital health literacy.

CONCLUSIONS

The mDiHERS is a validated tool for measuring patients’ readiness and ability to use digital health services. The mDiHERS assesses user characteristics, digital accessibility, literacy, and equity to contribute to the effective use of digital health services and improve accessibility. The development and validation of the mDiHERS emphasize the importance of confidence and competence in managing health digitally.

Authors: Pratiwi Citra Sari , Meliala Andreasta
Published: March 2024

Background: Remuneration is an important strategy to improve the competence of hospital services. Remuneration aims to motivate employees which can be achieved if the remuneration system is implemented fairly, but the gap between the ratio of the number of doctors and the average points to rates causes’ physician dissatisfaction toward the remuneration system.  Analyze satisfaction level and measure remuneration satisfaction factors on Pediatricians and Obstetrics and Gynecologists at ABC Hospital Jakarta.  Methods:This study used quantitative methods with multiple linear regression analysis measured by the Equity Scale and Remuneration Satisfaction Scale. Interviews were used to obtain comprehensive analysis results from respondents who were in the lower and upper limits of the questionnaire results. The interview also involved the management of ABC Hospital Jakarta.Results:Total 44 respondents consisting of 30 Pediatricians and 14 Obstetricians and Gynecologists, showed dissatisfaction with the remuneration system (45,46%), neutral (31,53%), and satisfied (23%). There was a relationship between perceptions of external fairness (P= 0,003) and procedural fairness (P= 0,002) with remuneration satisfaction. There was no relationship between perceptions of internal justice (P= 0,929) and perceptions of individual justice (P= 0,130) with remuneration satisfaction. These results were explored using interviews and the causes of doctor dissatisfaction due to the gap in the achievement of the Individual Performance Index, lots of doctor examinations that were not listed in the rates, and remuneration points did not consider the complexity of each job. Meanwhile, the dissatisfaction felt by the management was due to the lack of measurement of quality indicators in the remuneration system.Conclusion: External and procedural justices are factors that affect the satisfaction of remuneration felt by specialist-physician. The remuneration obtained at ABC Hospital Jakarta is lower than other Government Hospitals of the same type. In addition, there are binding rules, doctors' lack of understanding of the remuneration system, and lack of socialization. The management needs to formulate a more detailed remuneration system based on applicable regulations by adjusting the hospital situation.

Blockchain-Based Secure and Efficient Secret Image Sharing with Outsourcing Computation in Wireless Networks
Authors: Siddiqui Maha
Published: March 2024

Abstract: We present a novel solution, the Blockchain-based Secure and Efficient Secret Image Sharing (BC-SESIS) scheme, designed to enhance the security and efficiency of secret image sharing in wireless networks. Traditional Secret Image Sharing (SIS) methods generate multiple shadow images to distribute a secret image, allowing retrieval with a subset of these shadows. However, existing SIS schemes suffer from vulnerabilities, particularly during communication, where shadow images are susceptible to tampering and corruption, compromising security. Leveraging blockchain technology, BC-SESIS encrypts and stores shadow images securely within the blockchain, mitigating risks of tampering and corruption. A smart contract, empowered with identity authentication, ensures the requisite threshold (k, n) for secret image restoration. To alleviate computational burdens on smart contracts and users, we propose an efficient outsourcing computation mechanism. This method delegates the restoration task to agent miners within the encryption domain, ensuring secure execution. The effectiveness of the BC-SESIS scheme is substantiated through theoretical analysis and extensive experimentation. Results underscore its capacity to uphold communication security while delivering high computational efficiency within wireless networks.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Kim Eunyoung
Published: March 2024

Objectives The purpose of this study is to elucidate the figurative meanings of color terms in English.
Methods To achieve this, the thesis conducts a comprehensive study on the figurative meanings of the fundamental color terms in English, focusing on metaphor and metonymy. The primary colors examined are black, white, red, yellow, and blue.
Results The study reveals that the majority of color terms in English possess both referential and extended meanings. For instance, the color term ‘black’ is associated with various figurative meanings such as BADNESS IS BLACK, DEPRESSION IS BLACK, UNCONSCIOUS IS BLACK, ILLEGALITY IS BLACK, SURPLUS IS BLACK, ANGER IS BLACK, EVIL IS BLACK, SARCASM IS BLACK, UNKNOWN IS BLACK, BRUISED IS BLACK.
Conclusions Color terms demonstrate systematic motivation through semantic extension mechanisms. Most expressions exhibit metonymic motivation, forming the basis for numerous color terms that are subsequently extended metaphorically.
