Authors: Bagheri Khadijeh , Modanloo Mahnaz , Ahmadi Khatir Maryam , Kolagari Shohreh
Published: October 2024

Introduction: The aging population poses a significant social and healthcare challenge globally. The empty nest syndrome, where parents experience feelings of depression and loneliness when children leave home, is becoming increasingly prevalent. This study aimed to investigate the empty nests, depressive symptoms, and feelings of loneliness in the elderly population in Gorgan, Iran. Methods: This cross-sectional study was conducted in 2020, involving 234 elderly participants aged 60 and older, associated with comprehensive health centers. The participants were selected using a multi-stage sampling method. The data were collected through demographic questionnaires, the Geriatric Depression Scale, and the Social and Emotional Loneliness Scale for Adults, comprising romantic, family, and social loneliness subscales. Statistical analysis was performed using descriptive and analytical methods in SPSS version 22. The Spearman’s correlation was used to determine the relationship between the mean scores of depressive symptoms and feelings of loneliness. Group comparisons were conducted using the Mann-Whitney U test (P<0.05). Results: The study revealed that many elders experienced the empty nest phase (65.89%), with an average age of 63.02±7.97. About 53.2% reported mild to moderate depression levels and 57% feelings of loneliness. The family domain had the highest loneliness rate (76.0%), while the social domain had the lowest rate (50.0%). Individuals with empty nests had significantly higher loneliness scores (79.52±6.40) compared to those without empty nests (49.22±7.36) (P=0.008). No significant difference was observed in depression scores between the two groups (P=0.630). The results of the Spearman correlation test demonstrated a positive and significant relationship between loneliness and depressive symptoms in older adults (r=0.598, P<0.001). Conclusion: Implementing strategies such as conducting sessions with psychologists at healthcare facilities can help diminish feelings of loneliness and depression among this vulnerable group, ultimately improving their overall well-being.

Background: Comparing the existing curricula helps identify program strengths and weaknesses, provides an opportunity to improve the program, and fosters competition. This study aimed to conduct a comparative analysis of the Master’s curriculum in Critical Care Nursing between the University of Sharjah in the United Arab Emirates (UAE) and Iran University. Methods: This descriptive-comparative study was carried out in 2023 and compared the critical care nursing master’s programs at Iran and Sharjah University. Data were obtained from the websites of the Ministry of Health, Treatment, and Medical Education in Iran and Sharjah University in the UAE. Using Brady’s model, the two curricula were analyzed in four stages: description, interpretation, contiguity, and comparison, focusing on mission, vision, philosophy, goals of the department, acceptance conditions, program specifications and structure, course content, and student roles and duties. Results: The comparison revealed similarities in the philosophy, vision, and mission of both curricula. However, differences were also observed. The Iranian curriculum presents a general and understandable philosophy guiding high-level organizational performance. In contrast, the curriculum at University of Sharjah emphasizes the education of professional nurses with a focus on the use of technology, advances in critical care practice, and the implementation of evidence-based nursing. Iran focuses on minimizing mortality in critically ill patients, while Sharjah University adopts a global research-oriented approach, focusing on providing a creative and supportive environment. The mission in Iran is to train graduates to improve nursing care for patients needing special care, reduce mortality, and use their opinions for policy-making within the Samat system, whereas Sharjah University’s mission focuses on training nurses with modern scientific knowledge and teamwork skills to meet current and future needs. It focuses on service delivery to both the local community and beyond. The job position for graduates in Iran involves roles in both special departments and other unrelated centers, but Sharjah University focuses on the special care department. In Iran, the graduates of this field are prepared for caring, educational, research, and managerial roles and can work as clinical and educational faculty nurses. In contrast, graduates from Sharjah University are prepared for caring, supportive, and research roles and only work as bedside nurses. Conclusion: The strengths of the educational program for this course in Iran include the presence of working experience in hospitals for the admission of students, the use of evidence-based nursing care in the hospital, the strengthening of critical thinking, the provision of part-time courses, and the planning of courses aimed at faculty training.

Published: October 2024

Background: Blood pressure (BP) is an important measure of health that can be affected by various factors, including weight and sleep. Some students are exposed to problems related to sleep, weight, and BP. This study aimed at investigating the relationship between body mass, sleep quality, and BP in the operating room and nursing students of Hamedan University of Medical Sciences. Methods: The present cross-sectional study involved 191 operating room and nursing students from Hamadan University of Medical Sciences. The data were gathered using a demographic checklist and the Pittsburgh Sleep Quality Index (PSQI) questionnaire. BP and height were measured using the Bewell model W.M-61 hand-held BP monitor and a Stature Meter wall meter, respectively. Students’ weight was determined with a digital scale. The obtained data were analyzed using SPSS 24, with a significance level of 0.05. Results: Most of the students participating in the study were female (58.1), single (93.7), unemployed (90.6), and nursing students (59.7). The findings of the correlation test indicated a significant indirect relationship between sleep quality and systolic BP (SBP) (P=0.03, r=0.15). Additionally, there was a significant direct relationship between body mass index (BMI) and SBP (P=0.004, r=0.207). Conclusion: It seems that a high BMI in the operating room and nursing students can affect their sleep quality and BP. Thus, it is suggested that educational managers participate in physical activities and sports in the course, with appropriate plans for students. Their education should be in such a way to place the BMI in the normal range, prevent chronic diseases, and reduce the academic efficiency of the students.

Published: October 2024

The persistence of postoperative nausea and vomiting (PONV)episodes can cause further complications to the patient, such as: dehiscence of the surgical wound, dehydration, esophageal rupture, hematoma, hemorrhage, and may even lead to death. Considering its high incidence in surgical procedures of the face and oral cavity, the present study aimed to evaluate the incidence of PONV episodes in oral and maxillofacial surgeries under general anesthesia as well as to identify the main risk factors associated with these episodes. This analytical, observational, retrospective studywas based on the documentary analysis of 200 medical records of patients who underwentoral and maxillofacial surgery at the Walter Cantídio University Hospital of the Federal University of Ceará. Data on patient profile and surgical procedures were collected. PONV episodes were reportedin 9% of cases, with 100% occurring in the first 12 postoperative hours. Non-smoking patients, who underwent surgery viaintraoral access lasting 3 hoursor longer and with greater blood loss were more likely to experience PONV episodes. The identification of patients at greater riskas well as the understanding of the impact that certainsurgical procedures have on the occurrence of PONV are fundamental to plan and establish strategies to control PONV episodes.

On The Construction of a Newton-Like Iterative Scheme for Solving Non-Linear Algebraic Equations with Third Order Convergence
Authors: U. A. ABASIEKWERE , E. E. NDIYO
Published: October 2024

In this work, we propose an algorithm for finding simple roots of non-linear algebraic equations based on Newton Raphson’s method which is a non-coupled variant of He’s formula [1]. The new iterative scheme is formulated by achieving a quadratic approximation of the Taylor’s polynomial by neglecting its cubic and higher order terms. The efficiency of the new numerical formula is shown by solving some examples with well-known classical methods in literature. It is seen that while the traditional Newton’s method is of quadratic convergence, this presented method ensures third-order convergence.

Authors: Yahia Abd Ellteaf , Hussein Shawgy
Published: October 2024

We follow the approach of [16], methodology with a bit change of symbols realizing the mentioned ordered of graph 𝐶∗-algebras equipped with generalised gauge actions, and characterise in terms of ordered groupoids and groupoid cocycles when two ordered graph 𝐶∗-algebras are isomorphic by a diagonal-preserving isomorphism that intertwines the generalised gauge actions. Similarly, we apply this characterisation to show that two Cuntz–Krieger algebras are isomorphic by a diagonal-preserving isomorphism that intertwines the gauge actions if and only if the corresponding one-sided subshifts are eventually conjugate, and that the stabilisation of two Cuntz–Krieger algebras are isomorphic by a diagonal-preserving isomorphism that intertwines the gauge actions if and only if the corresponding two-sided subshifts are conjugate.

Authors: Adeyeye Awogbemi Clement , Adekola Alagbe Samson , Oluwaseyi Ajao Isaac , Olusegun Koyejo Samuel
Published: October 2024

The present value of an annuity is the current value of the future payments from an annuity, given a specified rate of discount. The Future value of an annuity is the estimated value of current asset at specific time in the future based on an assumed growth rate. The future and present values of annuity were mathematically generated on the basis of interest rate theory. This was anchored on the fact that every compound interest problem involves the annual rate and the rate per compounding period. The derivations of both present and future values of annuity were established with real life applications. It was also shown that as the frequency of compounding periods increases, the compound amount behavior tends to exponential growth rate. It was deduced that effective rate of interest is a function of nominal rates and compounding periods.

Introdução: O sinal de Chilaiditi é caracterizado pela interposição de alças intestinais na região hepatodiafragmática e que causa o achado incidental de ar subfrênico.  Quando há sintomas relacionados a essa condição (especialmente os gastrointestinais) passa a se chamar de Síndrome de Chilaiditi (SCH). O presente estudo é uma revisão sistemática da literatura acerca do tratamento da SCH e que objetiva trazer atualizações de uma temática pouco explorada e rara na população, mas que pode causar complicações. Metodologia: utilizando a declaração PRISMA e os descritores  “síndrome de Chilaiditi” e “tratamento” na Biblioteca Virtual em Saúde, foram encontrados 41 artigos. Resultados: aplicados critérios de inclusão (artigos em inglês ou português entre os anos de 2019 e 2024) e retirando-se textos dentro dos critérios de exclusão (feitos em animais, textos repetidos ou que não se encaixavam no tema e ainda aqueles incompletos), restaram 10 artigos. Discussão: O diagnóstico da SCH geralmente ocorre ao acaso, por meio de exames de imagem que irão identificar a parte do intestino fora do seu espaço habitual. A cirurgia é feita apenas em casos necessários (fluxo intestinal de fato comprometido, sinais de isquemia de alças ou risco de morte). Repouso, administração de fluidos hídricos, medicamentos sintomáticos e descompressão nasogástrica ou retal são boas medidas iniciais. Já as cirurgias podem envolver retirada de parte do intestino ou apenas o realocamento com fixação para se evitar recidivas. Conclusão: A SCH é uma condição rara e que tem como diagnósticos diferenciais o abscesso subfrênico e o pneumoperitônio. O tratamento é, na maioria das vezes, conservador. Caso o paciente não melhore, deve-se suspeitar de condições mais graves ou de doenças e alterações que interfiram nessa melhora, de modo que a equipe cirúrgica deve estar pronta para atuar.

A COMPREHENSIVE MULTIPERSPECTIVE FRAUD DETECTION MODEL FOR MULTI-PARTICIPANT E-COMMERCE SYSTEMS
Authors: SAVALLA ARUN KUMAR , SOWMYA KASTHURI
Published: October 2024

In the realm of e-commerce, where transactions involve multiple participants such as buyers, sellers, and intermediaries, the detection of fraudulent activities presents a significant challenge. To address this issue, our proposed method focuses on a Mult perspective approach aimed at enhancing fraud detection accuracy and efficiency. The first step involves the detection of user behaviors, wherein we leverage various techniques such as behavioral analysis and examination of transaction histories to gain insights into normal user behavior patterns. By understanding typical user interactions within the ecommerce ecosystem, we establish a baseline against which abnormal behaviors can be identified. Subsequently, we delve into the analysis of abnormalities for feature extraction. Utilizing sophisticated anomaly detection algorithms, we scrutinize transaction data to uncover irregular patterns indicative of potentially fraudulent activities. This process allows us to extract important features that serve as key indicators for fraud detection. Finally, we employ an ensemble classification model to implement our fraud detection mechanism, avoiding reliance on a specific algorithm. Instead, we leverage the strengths of ensemble algorithms, such as Random Forest, Gradient Boosting, or AdaBoost. By feeding the extracted features into the ensemble model, we train it to discern between legitimate and fraudulent behaviors in multiparticipant e-commerce transactions.

Published: October 2024

By creating an Advanced Portable Bomb Detector Box and using the capabilities of the Raspberry Pi Pico, this project presents a novel approach to bomb detection. To improve the accuracy and range of bomb impact detection, the system combines three essential sensors: an ultrasonic sensor, a gas detector, and a temperature detector. The impact range of a prospective explosive device may be determined by measuring the distance with the help of the ultrasonic sensor. Concurrently, the gas detector detects and examines gases released upon the impact of a bomb, providing important information about the composition of the explosive substance. By identifying distinct bomb types by their distinctive thermal fingerprints, the temperature detector enhances the study even further. An LCD monitor installed on the top of the detection box shows the gathered data in real time. Important facts such the kind of explosive substance, detection range, and specifics about the bomb hit are shown on this display. Security and emergency response teams may benefit from a portable and effective solution thanks to the integrated sensor suite and Raspberry Pi Pico, which allow quick and precise detection. This Advanced Portable Bomb Detector Box combines cutting-edge sensor technology with the adaptability of the Raspberry Pi Pico platform to provide a proactive approach to security, making it an indispensable tool in thwarting possible attacks.

Authors: Mr. N.Gopikrishna  , Tharun Eega
Published: October 2024

Stress assessments are required for a great deal of plant components, including the pressure vessel. A pressure vessel is a container designed to store liquids or gases at pressures much higher than the surrounding air. The finite element analysis of pressure vessels with various types of heads that maintain the same cylindrical volume and thickness is the focus of this project. The intended pressure vessel is made for 8 bar of pressure and 24 lit of volume in accordance with ASME standard section VIII, division I. In order to identify the source of the stress concentration zone in each kind of pressure vessel head at the same volume and reasonable pressure, certain end connections are evaluated under FEA. The project's goal is to use Ansys software to analyse various designs and static and thermal data. It finds that elliptical and flat head pressure vessels have lower distributed stresses than other types of heads, making them the preferred choice for most applications. It displays the fundamental construction and uses finite element modelling to analyse pressure vessels made of various materials, such as Nimonic 80A and SA516 Gr70, and with several types of heads under high stress conditions. In this project, we use the Finite Element tool to compute the estimated stresses that occur in cylindrical pressure vessels supported by two saddles under various end connection types. In order to determine the appropriate design and material, static structural analysis and thermal analysis are performed to compute the stresses in the vessel.

Authors: Sari Handayani Utami  , Irvan Medison  , Dewi Wahyu Fitrina  , Dessy Mizarti
Published: October 2024

Background: Pleural amebiasis is a rare manifestation of extraintestinal amebiasis, primarily occurring due to the rupture of an amebic liver abscess into the pleural space. We present an unusual case of pleural amebiasis in an elderly woman without any evidence of liver involvement.
Case presentation: A 78-year-old female presented with a two-month history of progressive dyspnea, cough, and right-sided chest pain. She had a history of consuming raw vegetables. Examination revealed right-sided pleural effusion, which was confirmed by chest radiography and thoracic ultrasound. Pleural fluid analysis showed exudative effusion and microscopic examination demonstrated the presence of Entamoeba histolytica trophozoites. Despite the absence of a liver abscess on abdominal ultrasound, the patient was diagnosed with pleural amebiasis based on the pleural fluid findings. She was successfully treated with metronidazole and drainage of the pleural fluid.
Conclusion: This case highlights the importance of considering pleural amebiasis as a differential diagnosis in patients with pleural effusion, even in the absence of liver involvement. Early diagnosis and prompt treatment with metronidazole and drainage are crucial for a favorable outcome.

The introduction of new agricultural technology has great importance in increasing production and productivity and technology transfer helps to achieve economic growth for developing countries. The adoption of agricultural technological innovations is conditioned by various factors considered holistically. This paper aims to assess the factors influencing the adoption of hybrid maize in Mbuye, Burundi. Primary data have been collected from a random sample of 365 small-scale farmers in January 2024 complemented by secondary data. Data were analysed using logistic regression. The results showed that the factors significantly influencing the adoption of hybrid maize in the area are the accessibility to extension services (x_3) (β=2.0024,p<0.01), membership in small-scale farmers’ associations (x_9) (β=1.9976,    p<0.01), non-agricultural activities (x_10)(β=-1.8275,    p<0.05)), access to land (x_11 )  (β=1.0770,    p<0.05), market orientation (sales) of production (x_12) (β=1.1049,    p<0.01), market accessibility (x_13) (β=1.2771,    p<0.01) and consumption (x_14) (β=-6.3716,    p<0.01). The factors of the sex of the head of household (x_1 ), age of household head (x_2), size of arable land (x_4), level of education (x_5), experience (x_6), access to credit (x_7), and household size (x_8 )  have a non-significant influence on hybrid maize adoption. The distribution and sales of improved seeds should be preceded by an awareness-raising campaign of their advantages (productivity) and disadvantages (input requirements, cultivation techniques, prohibition of seed saving at harvest, etc.). Increasing the number of extension services and providing them with financial and material resources is a factor in adopting hybrid maize. Small-scale farmers’ organizations would facilitate the flow of information linked to disseminating new agricultural technologies

DYNAMIC PACKET FILTERING USING MACHINE LEARNING METHODS
Authors:   Shakhrisabz Branch of Tashkent Chemical-Technological Institute, Uzbekistan, Tashev Sarvar Norboboyevich
Published: October 2024

With the emergence of the Internet, cyber-attacks and threats have become significant issues. Traditional manual network monitoring and rule-based packet filtering methods have become labor-intensive and less effective in combating attacks. Filtering packets based solely on payload and pattern matching is also inefficient. There is a need for a dynamic model capable of learning packet filtering rules. This article proposes a packet filtering model using Neural Networks. After developing the model classified with training and validation data, it can be utilized to support dynamic packet filtering. The proposed model allows filtering packets not only based on static rules but also considering IP packet attributes and rules learned by the model in advance. The model takes into account payloads and other IP packet attributes for filtering. It can automatically update firewall rules to enhance security.

Este estudio tiene como objetivo explorar las innovaciones en materiales, tecnologias y aplicaciones de recubrimientos en paredes para zonas húmedas en la provincia de Morona Santiago, especificamente en la ciudad de Macas, Ecuador. Para ello, se analizan variables clave como la evolución histórica de la industria de la pintura, los procesos de producción y los materiales tilizados en recubrimientos para zonas húmedas. La pintura desempeña un papel crucial no solo en el desarrollo estético de la arquitectura, sino también en la protección y mantenimiento de las superficies, lo que contribuye a la durabilidad del acabado y la integridad estructural. En este contexto, la industria de la pintura enfrenta desafios importantes derivados de los cambios climáticos, los cuales son determinantes para la calidad y longevidad de los recubrimientos. Metodológicamente, se adoptó un enfoque mixto, combinando análisis cualitativos y cuantitativos. Los datos fueron recabados mediante encuestas a 150 compradores habituales de la empresa Global Color, ubicada en Macas, Ecuador. Los principales resultados indican una alta aceptación de nuevas alternativas de recubrimientos para zonas húmedas en paredes en la provincia de Morona Santiago.
