Covid-19 cause many changed to the education field and the teachers. In normal situation and condition, teaching and learning process is done face to face at the class, but it is very different now. The teachers and the students have to do online learning using learning applications. These changed causes the stakeholders face much impact especially in the process of transferring the knowledge. This research aimed to describe the impact of Covid-19 in education field and teachers as agents of change. This research used literature study to find out related theories to the research problems. The research sources are journal, book, documentation, internet, and library and so on. The results show that Face to face learning has to move to daring learning at home using technology internet. The teachers have to learn more about how to use daring media as a tool in the teaching and learning process like how to apply Google classroom, Facebook, Twitter, Zoom, and YouTube. The teacher also needs to learn how to make an online attendance list, online materials, online quiz, online presentation or discussion, and so on. Not only the teacher but also the students will do the same thing as the teacher learns how to do daring learning at home.

Solving Redundancy Allocation Problems using Jaya Algorithm
Authors: Aswin B. , Lokhande Tapan , Gaonkar Rajesh S. Prabhu
Published: August 2023

Reliability-based design is related to the performance analysis of engineering systems. The redundancy allocation problem is one of the most common problems in the reliability-based design approach. The redundancy allocation problem determines the redundancy level of components in a system to maximize system reliability, subject to several constraints. In recent years, obtaining solutions to reliability-related redundancy allocation problems by means of evolving meta-heuristic algorithms has appealed to researchers due to the several drawbacks of classical mathematical methods. Meta-heuristics have shown the potential of obtaining precise solution in optimization problems and many techniques have been applied in the literature for optimal redundancy allocation. In this paper, a recently developed Jaya optimization algorithm is proposed to be applied for redundancy allocation to maximize system reliability. The Jaya algorithm is a simple, population-based intelligent meta-heuristic algorithm consisting of a single phase and an algorithm-specific parameter-less algorithm. This paper aims to present an application of the Jaya algorithm for searching the optimal solution of two redundancy allocation problems from the literature with nonlinear constraints so that system reliability is maximized. The first problem is the over speed protection system for a gas turbine, whose control system is modelled as a four-stage series system. The objective is to determine the optimal level of redundancy of the valves of the protection system under cost and weight constraints. The second one is the redundancy allocation problem of a five-stage series system with volume, weight, and cost constraints. The results are validated by comparing them with two other meta-heuristics.

Authors: Hasan Faeza , Abdoon Mohamed , Saadeh Rania , Berir Mohammed , Qazza Ahmad
Published: August 2023

Stochastic fractional differential equations are among the most significant and recent equations in physical mathematics. Consequently, several scholars have recently been interested in these equations to develop analytical approximations. In this study, we highlight the stochastic fractional space Allen-Cahn equation (SFACE) as a major application of this class. In addition, we utilize the simplest equation method (SEM) with a dual sense of Brownian motion to convert the presented equation into an ordinary differential equation (ODE) and apply an effective computational technique to obtain exact solutions. By carefully comparing the derived solutions with solutions from other articles, we prove the distinction of these solutions for their diversity and the discovery of new solutions for SFACE that appear in many scientific fields, such as mathematical biology, quantum mechanics, and plasma physics. The results introduced in this article were obtained by plotting several graphs and examining how noise affects exact solutions using Mathematica and MATLAB software packages.

Published: August 2023

Shortest path problem (SPP) has various applications in areas such as telecommunications, transportation and emergency services, and postal services among others. As a result, several algorithms have been developed to solve the SPP and related problems. The current paper extends the TANYAKUMU labelling method for solving the Travelling salesman problem (TSP) to solve SPP in directed transportation networks. Numerical illustrations are used to prove the validity of the proposed method. The main contributions of this paper are as follows: (i) modification of TSP algorithm to solve single source SPP, (ii) the developed method numerically evaluated on four increasingly complex problems of sizes 11×11, 21×21, 23×23 and 26×26 and lastly (iii) the solutions obtained from solving these four problems are compared with those obtained by Minimum incoming weight label (MIWL) algorithm. The proposed algorithm computed the same shortest paths as the MIWL algorithm on all four problems.
Secure Authentication and Data Transmission for Patients Healthcare Data in Internet of Medical Things
Authors: Patnaik Anup , Prasad Krishna K.
Published: August 2023

Currently, data transmission is an expanding area in healthcare, enabling health practitioners to examine, assess, and manage patients using mobile communication technologies. To identify and analyze a patient, healthcare providers need to access the physician's Electronic Medical Record (EMR), which may contain extensive audiovisual big data such as MRIs, CT scans, PET scans, X-rays, and more. To ensure accessibility and scalability for healthcare workers and consumers, the EMR needs to be stored in large data repositories on cloud servers. However, due to the sensitive nature of medical information stored in the cloud, the healthcare profession faces numerous security challenges, with data theft attacks being one of the most critical vulnerabilities. This research focuses on protecting medically sensitive data in the cloud by leveraging cloud computing facilities. The upgraded AES approach ensures that confidential data is securely accessible and stored. In addition, improved Elliptic Curve Cryptography (ECC) is utilized for key generation and validation. A hybrid optimization approach, combining robust optimization and genetic algorithms, is employed to select unique and distinct keys. Decryption is performed using deep neural networks, and Convolutional Neural Networks (CNN) enable batch encryption of multiple documents. The comparison between old methods and the proposed approach is based on encryption time, decryption time, and security strength.
An Algorithm for Constructing Support of Bent Functions by Extending a Set
Authors: Nelson Joseph , Srinivasan Chungath , Lakshmy K. V.
Published: August 2023

Boolean functions form the fundamental components of symmetric cryptographic systems, serving as the building blocks. Modifying bent functions makes it feasible to design Boolean functions with desired properties that exhibit high non-linearity. The current study offers a comprehensive analysis of bent functions through its support, culminating in the introduction of an algorithm for the systematic construction of four variable bent functions. This algorithm enables the complete generation of all 896 four-variable bent functions. Furthermore, we introduce a methodology for constructing n-variable bent functions (where n > 4), leveraging both the algorithm and an established secondary technique for bent function construction. Lastly, we examine the estimation of the count of bent functions by utilising certain properties associated with the support of bent functions.

Authors: Zhou Yue , Song Lijie , Xia Jin , Liu Huan , Xing Jingjing , Gao Jianbo
Published: August 2023

Background

Limited studies have observed the prognostic value of CT images for esophageal neuroendocrine carcinoma (NEC) due to rare incidence and low treatment experience in clinical. In this study, the pretreatment enhanced CT texture features and clinical characteristics were investigated to predict the overall survival of esophageal NEC.

Methods

This retrospective study included 89 patients with esophageal NEC. The training and testing cohorts comprised 61 (70%) and 28 (30%) patients, respectively. A total of 402 radiomics features were extracted from the tumor region that segmented pretreatment venous phase CT images. The least absolute shrinkage and selection operator (LASSO) Cox regression was applied to feature dimension reduction, feature selection, and radiomics signature construction. A radiomics nomogram was constructed based on the radiomics signature and clinical risk factors using a multivariable Cox proportional regression. The performance of the nomogram for the pretreatment prediction of overall survival (OS) was evaluated for discrimination and calibration.

Results

Only the enhancement degree was an independent factor in clinical variable influenced OS. The radiomics signatures demonstrated good predictability for prognostic status discrimination. The radiomics nomogram integrating texture signatures was slightly superior to the nomogram derived from the combined model with a C-index of 0.844 (95%CI: 0.783-0.905) and 0.847 (95% CI: 0.782-0.912) in the training set, and 0.805 (95%CI: 0.707-0.903) and 0.745 (95% CI: 0.639-0.851) in the testing set, respectively.

Conclusion

The radiomics nomogram based on pretreatment CT radiomics signature had better prognostic power and predictability of the overall survival in patients with esophageal NEC than the model using combined variables.
The effects of statins in patients with advanced-stage cancers - a systematic review and meta-analysis
Authors: Zhou Qiang , Jiao Zhihua , Liu Yuxi , Devreotes Peter N. , Zhang Zhenyu
Published: August 2023

Background

Statin therapy has been shown to reduce mortality in a wide range of cancer types and overall stages. Still, there is uncertainty about its efficacy in increasing survival among advanced cancer patients.

Methods

We conducted a meta-analysis with data from all studies that compared the hazard ratio of overall survival, cancer-specific survival, and progression-free survival in patients with advanced-stage cancer who receive statin therapy. Studies were selected from the PubMed, Embase, and Web of Science databases from their inception to December 31, 2022. Cancer types are limited to those rarely screened during the annual examination and more likely to develop into advanced stages, such as lung, pancreatic and ovarian cancers. This resulted in 27 studies eligible for meta-analysis.

Results

Statin therapy was associated with a 26% decreased risk of overall survival (HR, 0.74; 95% CI, 0.67, 0.81), 26% decreased risk of cancer-specific survival (HR, 0.74; 95% CI, 0.61-0.88), and 24% decreased risk of progression-free survival (HR, 0.76; 95% CI, 0.65-0.87) for advanced-stage cancer patients. The associations were not attenuated or reinforced by study design, study regions, cancer types, or other medical care. Concomitant use of other anticancer medications did not result in confounding effects.

Conclusions

Statin therapy produces significant benefits on overall survival and cancer-specific survival. Although the benefits might be lower than the approved immunotherapy medications, its cost-effectiveness could lead to dramatic health consequences. Concomitant use of statin drugs as cancer treatments is highly recommended in future clinical trials.

Introduction

The implementation of a telerehabilitation protocol for self-care in the routine of caregivers of individuals with amyotrophic lateral sclerosis (ALS) has been associated with reduced levels of stress and improved quality of life. Moreover, it may reduce the difficulty of traveling to perform physical or other self-care activities. Thus, this study designed a clinical trial protocol to investigate the effects of a self-care education program via telerehabilitation on the burden and quality of life of caregivers of individuals with ALS.

Methods

This single-blinded randomized clinical trial will recruit 26 caregivers and randomly allocate them to the experimental (EG = 13) or control group (CG = 13). The EG will receive an informative booklet and participate in a 6-week synchronous telerehabilitation program with a neuropsychologist, nutritionist, and physiotherapist to discuss physical and mental health. The CG will receive an informative booklet on self-care and physical activity and weekly phone calls for 6 weeks to solve questions about the booklet. Outcomes will include the caregiver burden (Zarit scale), quality of life (World Health Organization Quality of Life BREF), pain (McGill Pain Questionnaire), stress (Perceived Stress Scale), and depression (Beck Depression Inventory), which will be evaluated at the baseline after the six-week program and 30 days after the program. Additionally, we will assess daily the nocturnal awakenings, sleep patterns, level of physical activity, and heart rate variability.

Discussion

This study aimed to investigate the effectiveness of telerehabilitation for caregivers of individuals with ALS. If effective, this program could be disseminated among health professionals, increasing the possibility of remotely monitoring individuals with difficulty performing physical activities.

Published: August 2023

The article provides an overview of clinical manifestations of aggressive behavior in students with limited health capacities. The causes, mechanisms, and methods of medical and psychological correction of disorders that contribute to the prevention of various forms of maladaptation of children with limited health capacities in the context of the implementation of an inclusive education model are analyzed. An experimental study of 84 adolescents studying in the conditions of the inclusive education model was conducted. The methodology by A. Bass and A. Darki «Diagnostics of the State of Aggres sion» allowed determining the degree of severity and type of aggressive reactions. In order to assess the communicative characteristics of adolescents, the methodology «Assessing the relationship of a teenager with a class» was used. The questionnaire of interpersonal relations allowed evaluating the ways of a person's attitude to the people around. The main motives of bullying in the context of inclusive education are as follows: attracting attention by behavior that goes beyond school norms; self-asser tion over physically weaker children; protection or revenge, which may be compensatory reactions in response to systematic harassment; the fulfillment of leadership qualities in order to subdue weaker and dependent classmates. The results of the study make it possible to develop recommendations, the implementation of which will contribute to the prevention of maladaptive forms of behavior, such as interpersonal conflicts, verbal and physical aggression, and suicidal behavior. Only an integrated ap proach, including the activities of various specialists, i.e. psychiatrists, psychotherapists, neurologists, pediatricians, psychologists, teachers, and other specialists, will contribute to the successful implementation of an inclusive model of education for people with limited health capacities. The long-term result of the process is the formation of a common inclusive culture in modern Russian societ y.

The article presents the results of a comparative assessment of the effectiveness of the course application of therapeutic physical factors (alternating magnetic field and low-intensity laser radiation) in complex medical rehabilitation of patients with moderate and severe rhinosinusitis polyposa with uncontrolled course. It was shown that the use of genetically engineered biological therapy (GEBT) with dupilumab contributed to the positive dynamics of the clinical parameters of sinonasal polyposis. Complementing GEBT with the course application of an alternating magnetic field was accompanied by an increase in the regression of the main clinical manifestations of rhinosinusitis polyposa. The maximum corrective activity was noted in the group with the complex use of therapeutic physical factors — an alternating magnetic field and low-intensity laser radiation against the background of GEBT. The growth is based on the ability of the complex use of physiotherapeutic factors to cause the development of synergistic phenomena through the use of corrective effects of different modality, having different mechanisms of action. The physical factors under consideration are able to improve hemo- and microcirculation in the area of chronic inflammation, exhibit anti-inflammatory, analgesic, and trophic-stimulating effects, which, together with the inactivation of the main pro-inflammatory interleukins of type 2 inflammation, enhances the sanogenetic potential that determines the duration of remission. Taking into account the chronic relapsing nature of the rhinosinusitis polyposa course, it is planned to conduct prolonged studies covering a follow-up period of 1.5–2 years.

Erythromelalgia is a rare disorder characterized by episodic burning pain, erythema, and increased temperature. Most often, the pathological process affects the distal extremities. There are primary (hereditary) and secondary forms of the disease. It is considered that erythromelalgia is caused by abnormal vascular dynamics, in which capillary perfusion decreases, provoking tissue hypoxia. At the same time, there is an increase in arteriovenous shunting in the skin, which therefore appears erythematous, warm, and edematous. There are no universally effective protocols for the treatment of erythromelalgia, so the management of such patients is largely difficult. A 32‑year-old patient came to us with complaints of paroxysms of erythema, burning pain, and fever in the cheeks, nose, and ears. In addition to centrofacial erythema and subjective sensations of pain and burning, the patient's fingers turned white in the cold, then acquired a cyanotic color and, finally, a bright red color. Color changes were accompanied by pain sensations of tingling and burning. After a comprehensive examination of the patient by a rheumatologist, we assumed a rare diagnosis of isolated facial erythromelalgia. A combination of 2 intense pulsed light treatments (M22 Lumenis) and 3 plasmapheresis sessions (Haemonetics MCS) was successfully used as therapy. The manifestations of erythema significantly decreased, the intensity of facial burning reduced, and the titer of antinuclear factor normalized. The patient was satisfied with the results of the treatment. The article emphasizes the importance of managing patients with erythromelalgia by a multidisciplinary team of specialists, which ensures both a thorough differential search and verification of the diagnosis, and an integrated approach to therapy. In the absence of a universal and effective method for treating this pathology, the proposed therapy regimen may be of particular interest to clinicians of various specialties who are faced with such cases.

In the current economic conditions, state support for agribusiness entities is necessary to create a sustainable business climate in the country’s agro-industrial complex and address issues related to the country’s self-sufficiency in the main types of domestic agricultural products, raw materials and food. The main principles, mechanisms, specific measures of state support for agricultural producers and indicators for assessing the success of each segment at the macro level are defined in detail by legislative and other regulatory legal acts of the Russian Federation. To assess and analyze the effectiveness of state support at the micro level, various indicators and criteria have been proposed in modern domestic literature, but at the same time, as a review of sources has shown, there is no single and universal methodology. In order to understand the degree of impact of a particular area of activity of an economic entity on a change in the effectiveness of state support measures (and vice versa), it is necessary to develop a universal and comprehensive methodology for assessing the effectiveness of state support for agribusiness entities.

A New Text Encryption Scheme Suitable for Combating Sniffing Attacks in IoT Applications via Non-supersingular Elliptic Curves over Binary Extension Fields
Authors: Abukari Zakaria , Baagyere Edward Yellakuor , Iddrisu Mohammed Muniru
Published: August 2023

Several research works propose the use of Elliptic Curve Cryptography (ECC) to provide security for the Internet of Things (IoT) and cloud computing due to its shorter key requirement of approximately 160-571 bits vs. 1,024-15,360 bits of the others whilst achieving the same level of security. As a result, several ECC based text encryption schemes have been proposed in recent times. However, due to the mathematical foundations behind some of these schemes, there is the need for improvement to make them efficiently suitable for applications targeting IoT platforms. In addition, many of the existing schemes are either limited to some languages and/or use lookup tables which increase their computational overheads in terms of storage and processing. Against this background that this paper proposes a new ECC based text encryption scheme using efficient elliptic curve arithmetic to reduce the computational overheads. The scheme resists the major forms of sniffing attack in software implementation of ECC-based schemes. A test implementation proves that a very high key sensitivity is also achieved.

Published: August 2023

Academic stress is the type of stress most often experienced by students, especially those studying at Islamic boarding schools, because they have academic demands as students and santri. This study aims to determine the relationship between religiosity and academic self-concept and academic stress in students studying at Islamic boarding schools. This study uses a correlational quantitative approach. There were 114 students who participated in this study and were selected based on a simple random sampling technique. Data analysis used Sperman's Rho correlation technique because the normality assumption test results were not fulfilled. The results of the correlation test showed that there was a negative and significant relationship between religiosity and academic stress, and there was a negative but not significant relationship between academic self-concept and academic stress. This shows that there is a level of individual religiosity that plays a more significant role in academic stress than individual self-concept.

Published: August 2023

The motivation of the student causes the teaching experience to be more enjoyable for the student and results in better utilization of the teaching activity. The key is to identify where that motivation lies in order to adapt the content to the student's expectations. The objective of this work is to establish a method to identify the student's motivation regarding the training they are going to receive and be able to personalize the learning experience according to this motivation. To achieve this, we describe an experience in which a machine learning model of decision trees was trained using a voluntary survey generated through LinkedIn. By consulting the LinkedIn profiles of the respondents, a training dataset was created, which resulted in a model that achieved a 72% accuracy rate in a 10-fold stratified cross-validation. During the presentation of the students who enrolled in the activity, the necessary information was captured to generate a test dataset, which was used to validate the trained model. The accuracy rate of this validation was 100%. Although the sample size and predictors used are limited, we believe that this experience sufficiently illustrates the potential of artificial intelligence to identify student motivations and thus personalize the teaching experience, with the aim of increasing motivation and improving student performance.

Kentler, kolektif kültürün adaptasyon ortamlarıdır. Canlılık da bu davranışın yegane yaşamsal dışavurumudur. Süreç ve imkanların göstergesinde kolektif kültürün toplumsal sentezi, öngörüleri ve stratejileri aracılığıyla kentler uyumsal yaşam birimleri olmuşlardır. Geçilen her evre ile oluşan dönemsel normlar, kentlerde kendilerine yer bularak kolektif yapıya ulaşmış ve yönlendirilmişlerdir. Bu nedenledir ki kentler kolektif kültürün yaşamla buluştuğu ve kültüre ait olan sembolleri barındıran toplumsal ortamlar olmuştur. Sürece adaptif bir kimlik üretebilme karakteri ise kentlerin günümüz salgın koşullarında ne gibi oluşum ve dönüşümlere yol açağı sorunsalını ortaya koymuştur. Covid-19 ile kentler ve kültüre kazınan pandemi ortamı; kapalılık, sınırlılık ve izolasyon gibi alışıldık kollektif kültürle kesişmeyen yeni parametreleri doğurmuştur. Yeni kolektivite ve dolayısıyla yeni kültürel ortam, kentlerde sosyomekansal ortam üzerinde incelenmesi gereken konulardan olmuştur. Öte yandan, yeni kollektivite ortamı da küresel parametreler ile kamusal alanlarda kollektif yapının sadece bir kullanıcı haline geldiği sosyomekansal ortama paradoksal bir durum yaratmıştır. Yeni kolektivite, pandemi ile sosyomekansal ortamda karar mekanizması olarak tekrar etkin hale gelmiştir. Bundan dolayı, çalışma kapsamında kamusal alanlarda kollektif kültür ele alınmıştır. Geliştirilen aktarım şeması öncelikli olarak kamusal alanlarda kolektif kültürel ortamın yeniden yorumlamaları üzerine yoğunlaşmıştır. Sokak mobilyaları ve ticari kamusal mekanlara müdahaleler ele alınmış, ardından pandemi dönemi ile yapılan çalışmalarda ön plana çıkan pop-up yaklaşımlar aktarılmıştır.
