Published: October 2023

Aims:
Experiments were conducted to study the effect of using a perforated sill on maximum scour depth downstream from a sluice gate.

Background:

Previous studies have shown that screens may be utilized efficiently for dissipating the energy of water downstream of a hydraulic structure.

Objective:
For the present study, a series of experiments was conducted to investigate the effect of using a perforated screen sill on the maximum scour depth downstream of a hydraulic structure.

Methods: In the present study, a single perforated sill with varying porosity (10.3%, 18.3%, 28.5%, and 41.1%) and an inclination angle of 90° were used. Perforated sill with different shapes of holes (circular, rectangular, and square holes) was used during the study. The major parameters for the present study are the porosity of the perforated sill, different shapes of holes, downstream water depth, and the Gate Froude number (FG) for a range covering from 2.15 to 4.7. The gate opening simulating a hydraulic structure is adjusted at heights of 4 cm, 5 cm, and 6 cm during the experiments work.

Result:
The results revealed that an increase in the sill porosity (Ao/As) increases the screen effect to reduce the max scour depth. In addition, the results showed that the sill with square holes is better than the sill with circular and rectangular holes in reducing the maximum scour depth.

Conclusion:
The perforated sill with a square porosity of 41.1% reduces the maximum scour depth downstream of a sluice gate by 60%.

Abstract. Environmental awareness is an introspective behavior of environmental issues. This behavior is very important to develop, especially among schools. Because, in this era, many teenagers have been indifferent to environmental issues. Low environmental awareness, then low our gratitude to nature. The lack of awareness about nature can dilute the noble values in society. This study aims to determine the effect of environmental awareness on gratitude to nature in high school students. This research is a non-experimental quantitative study. Data collection using Environmental Awareness and Gratitude to Nature scales. The data analysis method uses simple linear regression. The sampling technique used was convenience sampling with a sample of 261 subjects. The results showed that there was an influence of 26,3% of environmental awareness on gratitude to nature.

New closed form solutions of some nonlinear pseudo-parabolic models via a new extended direct algebraic method
Authors: Hussain Akhtar , Ali Hassan , Zaman Fiazuddin , Abbas Naseem 
Published: October 2023

Abstract
Our investigation delves into a specific category of nonlinear pseudo-parabolic partial differential equations (PDEs) that emerges from physical models. This set of equations includes the one-dimensional (1D) Oskolkov equation, the Benjamin-Bona-Mahony-Peregrine-Burgers (BBMPB) equation, the generalized hyperelastic rod wave (HERW) equation, and the Oskolkov Benjamin Bona Mahony Burgers (OBBMB) equation. We employ the new extended direct algebraic (NEDA) method to tackle these equations. The NEDA method serves as a powerful tool for our analysis, enabling us to obtain solutions grounded in various mathematical functions, such as hyperbolic, trigonometric, rational, exponential, and polynomial functions. As we delve into the physical implications of these solutions, we uncover complex structures with well-known characteristics. These include entities like dark, bright, singular, combined dark-bright solitons, dark-singular-combined solitons, solitary wave solutions, and others.
Therapeutic potential and mechanisms of sacral nerve stimulation for gastrointestinal diseases
Authors: Wang Ximeng , Chen Jiande DZ 
Published: October 2023

Abstract

Background
The aim of this systemtic review is to introduce clinical applications (especially emerging) and potential mechanisms of sacral nerve stimulation (SNS) for treating various gastrointestinal diseases.

Materials and Methods
PubMed and Web of Science were searched for studies published on SNS and its clinical applications in fecal incontinence (limited to systematic review and meta-analysis of clinical studies), constipation (limited to reviews and randomized control clinical studies), irritable bowel syndrome (IBS), inflammatory bowel disease (IBD) and upper gastrointestinal motility disorders. The relevant studies were pooled, and their findings were summarized and discussed.

Results
SNS is an approved method for treating fecal incontinence. Systematic review and meta-analysis demonstrated high efficacy of the SNS therapy for fecal incontinence. Increased anal sphincter pressure and improvement in rectal sensation were reported as major mechanisms involved in the SNS therapy. SNS has also been proposed for treating constipation, but the therapy has been shown ineffective. There is a lack in SNS methodological optimization and mechanistic research. A few basic and clinical studies have reported the potential of SNS for treating visceral pain in IBS. SNS seemed capable of improving mucosal barrier functions. Several case reports are available in the literature on the treatment of IBD with SNS. Several laboratory studies suggested therapeutic potential of a special method of SNS for IBD. Cholinergic anti-inflammatory mechanisms were reported. Due to a recently reported spinal afferent and vagal efferent pathway of SNS, a few preclinical studies reported the potential of SNS for upper gastrointestinal motility disorders. However, no clinical studies have been performed.

Conclusions
SNS for fecal incontinence is a well-established clinical therapy. However, the current method of SNS is ineffective for treating constipation. Further methodological development and randomized clinical trials are needed to explore potential applications of SNS for IBS and IBD.

AbstractObjectiveEchocardiography (ECG) is the most common method used to diagnose heart failure (HF). However, its accuracy relies on the experience of the operator. Additionally, the video format of the data makes it challenging for patients to bring them to referrals and reexaminations. Therefore, this study used a deep learning approach to assist physicians in assessing cardiac function to promote the standardization of echocardiographic findings and compatibility of dynamic and static ultrasound data.MethodsA deep spatio-temporal convolutional model r2plus1d-Pan (trained on dynamic data and applied to static data) was improved and trained using the idea of “regression training combined with classification application,” which can be generalized to dynamic ECG and static cardiac ultrasound views to identify HF with a reduced ejection fraction (EF < 40%). Additionally, three independent datasets containing 8976 cardiac ultrasound views and 10085 cardiac ultrasound videos were established. Subsequently, a multinational, multi-center dataset of EF was labeled. Furthermore, model training and independent validation were performed. Finally, 15 registered ultrasonographers and cardiologists with different working years in three regional hospitals specialized in cardiovascular disease were recruited to compare the results.ResultsThe proposed deep spatio-temporal convolutional model achieved an area under the receiveroperating characteristic curve (AUC) value of 0.95 (95% confidence interval [CI]: 0.947 to 0.953) on the training set of dynamic ultrasound data and an AUC of 1 (95% CI, 1 to 1) on the independent validation set. Subsequently, the model was applied to the static cardiac ultrasound view (validation set) with simultaneous input of 1, 2, 4, and 8 images of the same heart, with classification accuracies of 85%, 81%, 93%, and 92%, respectively. On the static data, the classification accuracy of the artificial intelligence (AI) model was comparable with the best performance of ultrasonographers and cardiologists with more than 3 working years (P = 0.344), but significantly better than the median level (P= 0.0000008).ConclusionA new deep spatio-temporal convolution model was constructed to identify patients with HF with reduced EF accurately (< 40%) using dynamic and static cardiac ultrasound images. The model outperformed the diagnostic performance of most senior specialists. This may be the first HF-related AI diagnostic model compatible with multi-dimensional cardiac ultrasound data, and may thereby contribute to the improvement of HF diagnosis. Additionally, the model enables patients to carry “on-the-go” static ultrasound reports for referral and reexamination, thus saving healthcare resources.

Published: October 2023

The purpose of this study was to create a database of the chemical compounds – ligands of human steroid-hydroxylating cytochrome CYP19A1 (aromatase) in order to build a predictive model. The idea was to create a model on the basis of the machinery learning method such as random forest for two types of ligands – with steroidal (I type) and non-steroidal structure (II type). Two predictive models were built with the help of the KNIME analytical platform. Topological descriptors of the chemical structure were used as training data when building a model that takes into account their correlation between the structure of the molecule and the biological effect. The selection of the feature importance of the descriptors, optimal parameters of random forest and the definition of applicability domain of the models were carried out. The assessment of the ability to predict the results of a test sample was performed for each model. The quality marks of the obtained models indicated a rather high predictive ability of the models and the prospects of their use for identification of new human CYP19A1 ligands as potential drugs for treatment of hormone-dependent tumors.

Authors: Handriyanto Bamban , Lukmandono Lukmandono 
Published: October 2023

PT XYZ Food realized the importance of accurate costing strategies to increase company profitability. The traditional method of determining the cost of goods manufactured led to undercosting or overcosting, which further resulted in a low selling price. Therefore, the company implemented the Activity Based Costing (ABC) method to calculate the cost of goods manufactured by identifying and classifying activities into four levels and setting cost targets for each activity level. The results of the ABC method showed that the cost of Snack Series 10 gr was Rp. 17,246 per kg and Mie Sedap Series 9 gr was Rp. 17,247 per kg. Through pricing structure simulations, the company could reach the Highest Retail Price of Rp. 500 without reducing margins, and even the margin of ABC was greater than the traditional method. Thus, the use of ABC in determining the cost of goods manufactured can help companies increase profits and get accurate prices in a competitive market.

Background: Preauricular sinus (PrAS) is a common congenital external ear malformation affecting mainly children. Symptomatic Preauricular sinus and asymptomatic for unusual scar marks, surgery is the mainstay of treatment. Due to variationsin presentation and recurrence, surgeons practice different surgical procedures to treatthe Preauricular sinus.
Objectives: To compare the relative frequency and incidence of the Preauricular sinus and find the best surgical approach. Methods: It is a cohort retrospective study of forty-four cases of Preauricular sinus in the Department of Otorhinolaryngology and Head-Neck Surgery, Comilla Medical College, Bangladesh, from 01-07-2016 to 31-06-2019. All forty-four patients were clinically diagnosed with Preauricular sinus and confirmed by history, examination, and investigations. Special investigations included Audiological analysis and Ultrasonography of the renal system.
Results: Theincidence of Preauricular sinus out of 1,16,128 patients in the outpatient department was 44 (0.05%), and out of inpatient routine operative 2738 patients were 1.61%. Fortypatients (90.90%) were treated by traditional sinusectomy, and the rest of the four patients (9.10%) were treated by extended supra-auricular sinusectomy procedures. Relapse was taken place in two patients (4.54%). Gender issuance shows that female was 24(54.54%) and males was 20(45.46%). The age distribution exhibited in the case of children was 34(77.27%), and adult, was 10(22.73%). Anatomical site allocation reveal that right side was 22(50%), left side was 20(45.45%), bilateral was 2(4.55%) whereas unilateral was 42(95.45%). Presenting features display non-infected putty like discharge was 21(47.72%), infected abscess was 19(43.18%) and asymptomatic was 4(9.1%). A syndrome related tothe Preauricular sinus was not found in our study.
Conclusion: Children were more affected by the Preauricular sinus as a congenital disease. Incidence and recurrence are always countable fromthe perspective of treatment. As surgery is the treatment principle, it should be perfect without recurrence. We appreciate the supra-auricular approach for the excision of the Preauricular sinus, which best complements the patient’s wishes.

Authors: Berezivska Larysa D. , Mikhno Oleksandr P. , Pinchuk Olha P. 
Published: October 2023

The article deals with the relevant issue of using social media in the context of open science to disseminate the results of scientific research and implement the mission of institutions of social memory – libraries and museums – to preserve, study and popularize the national pedagogical heritage. It has been revealedthat in foreign and Ukrainian historiography there are no special studies on the spread of biographical knowledge in social networks. The online project is considered both as a multifunctional information resource and as a digital tool for educational activities, which, with the help of web technologies, demonstrates specially created open-access content to a wide range of users. For the first time, the paper analyzes the spread of biographical pedagogical knowledge through the development of online projects and their implementation by means of social networks. Biographical online projects of V. O. Sukhomlynskyi State Scientific and Educational Library of the National Academy of Educational Sciences of Ukraine and the Pedagogical Museum of Ukraine are characterized by the following parameters: systematized information in the form of a table (implementation model, name, web resource where the project was implemented, implementation period, hashtag), grouping by type (collective, individual, calendar, thematic), a brief description of the content of each project, a graphic layout of the project. The examples of biographical online projects have been given. The article reveals thetrend of an increase in the number of biographical online projects in the Ukrainian segment of the Facebook social network during 2020–2022, caused by the decolonization of the Ukrainian humanities. 4 proven models for implementing biographical online projects have been proposed for a widespread use: "Online project on Facebook", "Online project on Facebook and Instagram", Online project on Facebook using a web portal/website", Online project on Facebook as a source ofvirtual exhibition on the website". It has been proven that the use of social networks for the dissemination of pedagogical biography in the form of online projects in the educational and scientific space is not only an effective way of providing access to the results of scientific research to a wide audience, but it also contributes to the restoration and preservation of the national memory.
Interpetrosal sphingosine-1-phosphate ratio predicting Cushing’s disease tumor laterality and remission after surgery
Authors: Sun Heng , Wu Chunli , Hu Biao , Xiao Yuan 
Published: October 2023

BackgroundCushing’s disease (CD) poses significant challenges in its treatment due to the lack of reliable biomarkers for predicting tumor localization or postoperative clinical outcomes. Sphingosine-1-phosphate (S1P) has been shown to increase cortisol biosynthesis and is regulated by adrenocorticotropic hormone (ACTH).MethodsWe employed bilateral inferior petrosal sinus sampling (BIPSS), which is considered the gold standard for diagnosing pituitary sources of CD, to obtain blood samples and explore the clinical predictive value of the S1P concentration ratio in determining tumor laterality and postoperative remission. We evaluated 50 samples from 25 patients who underwent BIPSS to measure S1P levels in the inferior petrosal sinuses bilaterally.ResultsSerum S1P levels in patients with CD were significantly higher on the adenoma side of the inferior petrosal sinus than on the nonadenoma side (397.7 ± 15.4 vs. 261.9 ± 14.88; P &lt; 0.05). The accuracy of diagnosing tumor laterality with the interpetrosal S1P and ACTH ratios and the combination of the two was 64%, 56% and 73%, respectively. The receiver operating characteristic curve analysis revealed that the combination of interpetrosal S1P and ACTH ratios, as a predictor of tumor laterality, exhibited a sensitivity of 81.82% and a specificity of 75%, with an area under the curve value of 84.09%. Moreover, we observed that a high interpetrosal S1P ratio was associated with nonremission after surgery. Correlation analyses demonstrated that the interpetrosal S1P ratio was associated with preoperative follicle-stimulating hormone (FSH), luteinizing hormone (LH), and postoperative ACTH 8 am levels (P &lt; 0.05).ConclusionOur study demonstrated a significant association between the interpetrosal S1P ratio and tumor laterality, as well as postoperative remission in CD, suggesting that the interpetrosal S1P ratio could serve as a valuable biomarker in clinical practice.
