Efficient Hybrid CNN Method to Classify the Liver Diseases
Authors: Modhugu Venugopal Reddy
Published: October 2023

This study focuses on classifying liver diseases using dynamic CT scan images and deep learning techniques. The primary objective is to develop accurate and efficient models for distinguishing between different liver disease categories. Three deep learning models, ResNet50, ResNet18, and AlexNet, are employed for three-class classification, including Hepatitis/cirrhosis, Hepatitis/Fatty liver, and Hepatitis/Wilson's Disease. The dataset comprises dynamic CT scan images of the liver, each manually segmented to identify lesions. To enhance model performance, the data is pre-processed by resizing, normalization, and data augmentation. The dataset is split into training, validation, and test sets for model evaluation. The performance of each model is assessed using confusion matrices, accuracy, sensitivity, and specificity. Results show varying accuracies for different liver disease classes, indicating the strengths and limitations of the models. To overcome the limits of the three-class classifiers, a framework for the Efficient Hybrid CNN method to classify Liver diseases (EHCNNLD) is proposed, combining the predictions from the three models with weighted probabilities. The Proposed EHCNNLD method demonstrates improved accuracy and classification power, enhancing the overall performance for liver disease classification. The study highlights the potential of deep learning techniques in medical image analysis and clinical diagnosis. The findings provide valuable insights into developing robust and accurate models for liver disease classification, paving the way for medical research and patient care advancements.
Multidirectional Trust-Based Security Mechanisms for Sinkhole Attack Detection in the RPL Routing Protocol for Internet of Things
Authors: Khoeurt Sopha , So-In Chakchai , Musikawan Pakarat , Aimtongkham Phet
Published: October 2023

The Internet of Things (IoT) has gained popularity in recent years by connecting physical objects to the Internet, enabling innovative applications. To facilitate communication in low-power and lossy networks (LLNs), the IPv6-based routing protocol for LLNs (RPL) is widely used. However, RPL’s lack of specified security models makes it vulnerable to security threats, particularly sinkhole attacks. Existing sinkhole attack detection techniques suffer from high detection delays and false positives. To overcome these limitations, in our research we propose a multidirectional trust-based detection approach for sinkhole attacks in the RPL routing protocol. Our model introduces a novel architecture that considers trust in parent, child, and neighbor directions, reducing detection delays. We enhance detection efficiency and reduce false positives by combining fuzzy logic systems (FLSs) and subjective logic (SL). Additionally, we introduce a new trust weight variable derived from Shannon's entropy method and multiattribute utility theory. We adaptively adjust the SL coefficient based on network conditions, replacing the constant coefficient value of SL theory. Our approach is compared to the most recent techniques, and we assess different indicators, such as false-positive rate, false-negative rate, packet delivery ratio, throughput, average delay, and energy consumption. Our results demonstrate superior performance in all these metrics, highlighting the effectiveness of our approach.
Enhancing Security in Mobile Ad Hoc Networks: Enhanced Particle Swarm Optimization-driven Intrusion Detection and Secure Routing Algorithm

Wireless technologies have grown in popularity and are used in many applications. Transient Mobile Ad hoc Networks (MANETs) serve specific goals without infrastructure. The dynamism of these networks makes them useful for ubiquitous computing. However, high mobility, the lack of a centralized authority, and open media make MANETs vulnerable to various security risks. Thus, an Intrusion Detection System (IDS) should be used to monitor and detect system security issues. To prevent and improve security against unauthorized access, intrusion screening is crucial. The depletion of a mobile node's power supply can impact its capacity to transmit packets, as this functionality is contingent upon the system's overall lifespan. Computational Optimization-driven solutions have been prevalent in the context of IDS and secure routing inside MANETs. This research employs the Enhanced Particle Swarm Optimization-driven Intrusion Detection and Secure Routing Algorithm (EPSO-IDSRA). Enhanced Particle Swarm Optimization technique (EPSO) has provided confidence-based, secure, and energy-efficient routing in MANETs. The EPSO technique is applied to identify optimal hops for enhancing the routing process. The initial step involves the activation of the fuzzy clustering algorithm, followed by selecting Cluster Heads (CHs) based on assessing their indirect, direct, and recent confidence values. Furthermore, the identification of value nodes was contingent upon assessing confidence levels. Also, the CHs are involved in multi-hop routing, and determining the optimal route depends on the anticipated protocol, which chooses the most favorable paths considering factors such as latency, throughput, and connectivity within the designated area. The EPSO method, presented for secure routing (at time 50ms), yielded an optimal energy consumption of 0.15 millijoules, a minimal delay of 0.008 milliseconds, a maximum throughput of 0.8 bits per second, and an 89% detection rate.

Published: October 2023

The Pancasila student profile is a national education goal. The Pancasila student profile is a reference for educators in building the character and competence of students. The aim of this research is to find out the application of the Pancasila student profile in the independent curriculum in elementary schools and also to find out the obstacles faced by teachers during its implementation. This research method is qualitative with a case study type. The data collection technique uses interviews, observation and documentation. Data sources involve the school principal, 2 teachers and 2 students. Testing the validity of the data uses triangulation. Data analysis techniques include data collection, data reduction, data presentation and drawing conclusions. The results of the research show that the teacher has implemented the Pancasila student profile even though all of these applications can be realized well by the students themselves. The obstacles faced by teachers in implementing the Pancasila student profile are the different characteristics and abilities of students, lack of motivation from parents and advances in technology. The conclusion from the research results is that the form of implementation carried out by teachers is to familiarize students with always saying greetings, reciting prayers, instilling an attitude of loving tradition, respecting diversity and training students to be able to work together with each other and have an attitude of responsibility.

CORPORATE GOALS OF SPONSORSHIP IN SPORTS
Authors: Ratković Milijanka
Published: October 2023

The two-sided focus of sponsorship goals in sports is present due to the existence of two parties in the sponsorship relationship. The buyer of sponsorship and the seller of sponsorship have different goals, but they also have common goals related to the interest to realize the sponsorship according to the plan, as well as to achieve the maximization of the effects of the expectations of both parties. That common interest is of primary nature and leads to partnership. The separate goals of the participating parties are defined in such a way that mutual interest gets fulfilled. The goals of corporate sponsors are determined by motives, and in most cases they are external and opportunistic, that is, commercial. However, the goals can be also internal and altruistic, and as such focused on highlighting other benefits, such as building good relationships with employees and other participants in the value delivery chain that the sponsor promotes, including the public. The analysis that follows is based on literature research and already existing conclusions regarding the nature of goals and motives in sponsorship. The aim of this paper is to verify the existing conclusions of the focus of sponsorship objectives in sports. The content analysis method led to the conclusion that the goals of sponsorship in sports can be defined through the categories of market, society, relationships and clan. This confirms the conclusions of previous research.

Published: October 2023

Fe-based hardfacing with TiC reinforcement receives considerable attention due to the optimal quality-price ratio. The present research focuses on the investigation of microstructure and abrasive wear behavior of Fe-based hardfacing with TiC, in-situ synthesized from TiO2. The plasma transferred arc (PTA) cladding method was used for in-situ synthesis of TiC on the S235 steel substrate using 72 hours ball-milled AISI 316L stainless steel (ss), TiO2, and graphite powders. Scanning electron microscopy (SEM) was used to analyze the microstructure, and energy dispersive spectroscopy (EDS) analysis was used to determine the distribution of TiC. XRD analysis was used to define the phase composition. Vickers hardness was measured, and ASTM G65 abrasion test was applied to evaluate the wear resistance of the hardfacings. Wear mechanisms were studied under SEM.

PERCEPCIONES DE NIÑOS, JÓVENES Y ENTRENADORES DEL CLUB GRAMA DEPORTES DE IBAGUÉ SOBRE LA EDUCACIÓN EN VALORES EN EL FÚTBOL BASE
Authors: Jimenez Leonel Andres Felipe , Reyes Oyola Felipe Augusto , Palomino Devia Constanza
Published: October 2023

El deporte es utilizado para fomentar actitudes y conductas positivas, para transmitir valores de compañerismo, respeto, esfuerzo y deportividad, pero también se observan situaciones poco gratificantes y agradables en el entorno de los grupos que pueden repercutir en la formación integral del niño. Frecuentemente, el fútbol infantil imita el profesional, situación que ha llevado a muchos entrenadores, padres, espectadores, directivos, niños y jóvenes a reproducir actitudes del fútbol profesional más que del fútbol educativo y formativo. Así, el objetivo principal del estudio fue valorar las percepciones que subyacen en niños, jóvenes y entrenadores del Club Grama Deportes de Ibagué sobre la educación en valores en el fútbol base. Para ello se realizó una investigación con enfoque cuantitativo, de tipo descriptivo. Se diseñaron y validaron dos encuestas, que fueron aplicadas a 128 niños y adolescentes entre los 7 y los 16 años, de las categorías pre-baby, baby, pre-infantil, infantil, pre-juvenil y juvenil, y 5 entrenadores con edades entre los 26 y 53 años. Los resultados revelaron que se debe fortalecer la formación en valores, teniendo en cuenta que el juego limpio debe estructurarse sobre una sólida formación en estos grupos. Así mismo, de la percepción de los niños, jóvenes y entrenadores, se puede inferir que no existe una política  en valores en la Escuela de Fútbol Grama Deportes. Dado lo anterior, se recomienda el diseño de un programa de actualización y cualificación de sus entrenadores, de tal manera que se garantice  la formación integral.

Authors: Zhao Keyan , Li Baoyin , Guo Xiaodong , Sun Biao , Wang Yang , Tao Dengshun , Wang Qiguang , Wang Huishan
Published: October 2023

Background: Ventricular septal rupture (VSR) following myocardial infarction (MI) is a rare but lethal complication. We analyzed the long-term results and risk factors for survival in the treatment of VSR. Methods: From January 2012 to December 2021, 115 consecutive patients with post-MI VSR were admitted to our hospital. Depending on different treatment methods patients were divided into following three groups: medical, transcatheter intervention, and surgical repair. During the study, relevant clinical data, operation-related conditions, and follow-up data were analyzed. The Kaplan–Meier method and log-rank test were used to determine the cumulative incidence of mortality. The independent risk factors for patient mortality were evaluated by multivariate logistic regression. Results: The mean follow-up time was 43.4 ± 34.7 months. The overall in-hospital, 30-day, and long-term mortality rates were 24.3%, 38.3%, and 51.3%, respectively. In the medical group, the in-hospital and 30-day mortality rates were 46.7 % (21/45) and 82.2 % (37/45), respectively, with only three patients alive at follow-up. In the transcatheter intervention group, 30-day and long-term mortality rates were 12% and 28%, respectively. In the surgical repair group, 30-day and long-term mortality rates were 8.9% and 22.2%, respectively. Compared with the surgery-group patients, patients with transcatheter intervention had a longer time from VSR to intervention. Logistic regression analysis revealed that age, previous infarction, Killip class, serum creatinine, Troponin T, N-terminal pro-B-type natriuretic peptide, and medical strategy were risk factors for all-cause mortality. Conclusions: The 30-day and long-term outcomes of patients treated with surgical repair and transcatheter intervention were significantly better than medically treated patients.

Published: October 2023

Purpose: The association between appendicular skeletal muscle mass (ASM) and cardiometabolic risk has been emphasized. We estimated reference values of the percentage of ASM (PASM) and investigated their association with metabolic syndrome (MS) in Korean adolescents.Methods: Data from the Korea National Health and Nutrition Examination Survey performed between 2009 and 2011 were used. Tables and graphs of reference PASM were generated using 1,522 subjects, 807 of whom were boys aged 10 to 18. The relationship between PASM and each component of MS in adolescents was further analyzed in 1,174 subjects, 613 of whom were boys. Moreover, the pediatric simple MS score (PsiMS), the homeostasis model assessment of insulin resistance (HOMA-IR), and the triglyceride-glucose (TyG) index were analyzed. Multivariate linear and logistic regressions adjusting for age, sex, household income, and daily energy intake were performed.Results: In boys, PASM increased with age; the trend was different in girls, in whom PASM declined with age. PsiMS, HOMA-IR, and TyG index showed inverse associations with PASM (PsiMS, β=-0.105, P<0.001; HOMA-IR, β=-0.104, P<0.001; and TyG index, β=-0.013, P<0.001). PASM z-score was negatively associated with obesity (adjusted odds ratio [aOR], 0.22; 95% CI, 0.17–0.30), abdominal obesity (aOR, 0.27; 95% CI, 0.20–0.36), hypertension (aOR, 0.65; 95% CI, 0.52–0.80), and elevated triglycerides (aOR, 0.67; 95% CI, 0.56–0.79).Conclusion: The probability of acquiring MS and insulin resistance decreased as PASM values increased. The reference range may offer clinicians information to aid in the effective management of patients. We urge clinicians to monitor body composition using standard reference databases.

Small-Scale Socio-Economic Conditions and Residential Segregation: Evidence from the Municipalities Across the Metropolitan Region of Attica
Authors: Psycharis Yannis , Panori Anastasia
Published: October 2023

Residential segregation gained a new momentum after the turn of the new century. The pace of urbanization that has been observed over the last two decades has been proceeding hand in hand with the increasing residential segregation in large cities and metropolitan areas. The international literature is flourishing with studies on residential segregation. This paper investigates residential segregation trends in the Metropolitan Region of Attica during the period 2004-2019. The analysis is based on a database combining individual household data from the EU-SILC, as well as data from official national sources. The paper applies the Dissimilarity Index for measuring residential segregation trends based on occupation, education and living conditions, before, during and after the economic crisis. We also use the Gini index for comparing income inequality with residential segregation trends. Our analysis shows that between 2004 and 2019, residential segregation intensified between the top and bottom socio-economic groups, whilst an inclusive trend has been recorded between middle-class groups and the other two categories. The results do not suggest any similar patterns between residential segregation and income inequality. The evidence derived from this study is relevant to public policy, inclusive growth and development.
Does Cross-Border-Establishment Improve Competition and Performance of Indonesia’s Financial Sector?
Authors: Heni Nugraheni  , Satrio Nugroho  , Azizah Surayya Warman
Published: October 2023

This study examines the effects of cross-border establishment of financial institutions on competition level in Indonesia’s financial sector. We use sample data on all conventional banks, securities firms, life and general insurance companies from 2013-2020. To measure competition, we use Lerner index, Boone indicator and Panzar-Rosse. Our analysis shows that the entry of foreign financial institutions may increase the competition in the financial sector. Further analysis shows that the increasing competition have positive impact to profitability and intermediation, reflected by the return on asset, loan ratio, transaction value, and insurance premium income to total asset ratio. However, foreign financial firms tend to have higher market power compared to domestic counterparts due to the efficiency in doing their businesses. Hence, domestic financial institutions need to boost efficiency, particularly through the adaption of technology and capacity enhancement of human resources, in order to compete with more advanced foreign financial firms.

This research was conducted to offer a concept for the implementation of higher education libraries, where we know that the higher education library is one of the units whose existence is to support the implementation of education organized by tertiary institutions. The role and function of the library towards the Tri Dharma of Higher Education so far seems to be limping, that is because the new ones that are running support education and even then it is not optimal, while research and community service seem to be separated from the role of the library. Here the author offers that the management and organization of the library can pay attention to academic culture, what needs to be built is the academic cultural infrastructure and making Public Relations a strategic step in manipulating the habit of neglecting the library in the implementation of the Tri Dharma. The type of approach used is comparative qualitative with a qualitative approach. Data collection was used with data collection techniques in the form of articles, books, regulations, websites and other sources related to the problem under study. The collected data is studied by linking the phenomena that occur so as to give birth to an interpretation or view then arranged systematically so as to produce a view or concept that can be applied by managers in organizing libraries, especially in supporting the implementation of the Tri Dharma of Higher Education
Simmelian Contributions to a Relational Sociology of Senses and Emotions: the Case of “Platforms of Delivery Workers”

In The View of Life, the last Simmel criticizes the Kantian approach to Ethics, because it considers the individual exclusively from his rational dimension, leaving aside his sensitivity; that is, "temptation and seduction by the senses." At the same time, he warns about the dangers for modern life of the technical expansion of the sensitive world, such as when “a being who has the structure of a giant telescope” or legs, “half-kilometer stilts” is conceived.

Beings conceived in these way are today the delivery workers. Riding around the city very fast their bikes or motorcycles, receiving orders from their cellular phones, they administrate their bodies and senses –especially the view- at the service of their self-entrepreneurship. The article examines for the case of Buenos Aires, this emerging phenomenon of contemporary capitalism, such as the constitution of precarious working relationships between distributors of the current platform companies of delivery

Objective: To assess whether local anesthetic infiltration could minimize the carotid baroreceptor reflex (CBR) which has an incidence after carotid artery stenting (CAS) that varies from 29% to 51%.Methods: This retrospective single-center study included 51 patients (mean age, 70.47 years) who underwent CAS for carotid stenosis. The groups included patients who underwent CAS for asymptomatic ischemic stroke (n=41) or symptomatic disease (n=10). Preprocedural percutaneous lidocaine injections (PPLIs) were administered to 70.6% and 5.9% of patients who underwent elective CAS and emergency CAS, respectively.Results: Among patients who received PPLIs, the mean degree of stenosis was 80.5% (95% confidence interval [CI]: ±10.74, 51–98%). The mean distance from the common carotid artery bifurcation to the most stenotic lesion (CSD) was 8.3 mm (95% CI: ±0.97, 6.3–10.2 mm); the mean angle between the internal carotid artery and common carotid artery (CCA) trunk (IAG) was 65.6° (95% CI: ±2.39, 61–70°). Among patients who did not receive PPLIs, the mean degree of stenosis was 84.0% (95% CI: ±8.96, 70–99%). The mean CSD was 5.9 mm (95% CI: ±1.83, 1.9–9.9 mm); the mean IAG was 60.4° (95% CI: ±4.41, 51–70°). The procedure time was longer in the PPLI group than in the no PPLI group (28.19 [n=39] vs. 18.88 [n=12] days) (P=0.057); the length of intensive care unit stay was shorter in the PPLI group (20.01 [n=36] vs. 28.10 [n=5] days) (P=0.132).Conclusions: Targeted PPLI administration to the carotid bulb decreased aberrant heart rates and blood pressure changes induced by carotid stent deployment and balloon inflation. As CBR sensitivity increases with decreasing distance to the stenotic lesion from the CCA bifurcation, PPLIs may help stabilize patients during procedures for stenotic lesions closer to the CCA.

Two-dimensional magnetic materials are emerging materials developed in recent years and have attracted much attention for their unique magnetic properties and structural features in single or few layers of atomic thickness. Among them, ferromagnetic materials have a wide range of applications such as information memory and processing. Therefore the current research is mainly focused on enriching the two-dimensional ferromagnetic database and developing modification strategies for magnetic modulation. In this paper, two-dimensional vanadium-doped Cr2S3nanosheets were successfully grown on mica substrates by atmospheric pressure chemical vapour deposition. The thickness and size of the nanosheets can be effectively regulated by changing the temperature and mass of vanadium source VCl3 powders, with the temperature of 765℃ and the mass of 0.010 g as the most appropriate conditions for the growth of nanosheets. The nanosheets were also characterised by optical microscopy, atomic force microscopy, raman spectroscopy, scanning electron microscopy, X-ray energy spectroscopy, X-ray photoelectron spectroscopy, and the nanosheets were regular in shape, with flat surfaces and controllable thicknesses, and high quality vanadium-doped Cr2S3 nanosheets were prepared. Meanwhile, the magnetic characterisation of the doped samples showed that the Curie transition temperature of the vanadium doped samples changed to 105 K, and the maximum magnetic moment point of 75 K in the M-T curve disappeared after V doping, and from subferromagnetic to ferromagnetic, and the coercivity in the M-H curve also increased significantly, which proved that the vanadium doping could effectively regulate the magnetic properties of Cr2S3 nanosheets. These results are expected to advance the possibility of vanadium-doped Cr2S3 materials toward practical applications and become one of the ideal candidate material for next generation spintronic applications.

Metabolic capacity can vary substantially within a bacterial species, leading to ecological niche separation, as well as differences in virulence and antimicrobial susceptibility. Genome-scale metabolic models are useful tools for studying the metabolic potential of individuals, and with the rapid expansion of genomic sequencing there is a wealth of data that can be leveraged for comparative analysis. However, there exist few tools to construct strain-specific metabolic models at scale. Here, we describe Bactabolize, a reference-based tool which rapidly produces strain-specific metabolic models and growth phenotype predictions. We describe a pan reference model for the priority antimicrobial-resistant pathogen, Klebsiella pneumoniae, and a quality control framework for using draft genome assemblies as input for Bactabolize. The Bactabolize-derived model for K. pneumoniae reference strain KPPR1 performed comparatively or better than currently available automated approaches CarveMe and gapseq across 507 substrate and 2317 knockout mutant growth predictions. Novel draft genomes passing our systematically defined quality control criteria resulted in models with a high degree of completeness (≥99% genes and reactions captured compared to models derived from matched complete genomes) and high accuracy (mean 0.97, n=10). We anticipate the tools and framework described herein will facilitate large-scale metabolic modelling analyses that broaden our understanding of diversity within bacterial species and inform novel control strategies for priority pathogens.
A part of the problem

In recent years, ordinary individuals with diverse health conditions have increasingly turned to social media platforms to share their experiences with illness. This trend has raised concerns regarding the informational value of these expressions, as well as the motivations behind them and their impact on viewers. This article is a critical examination of the textual characteristics and potential appeal of YouTube videos about depression uploaded by young Norwegian women who have personally experienced the disease. The discussion is grounded in a multimodal analysis of six videos. Utilizing Norman Fairclough’s concept of media discourse, the article explores three dimensions of these video blogs (vlogs): the representation of depression, their interaction with viewers and the identities of the vloggers. The analysis reveals that the vloggers do not disseminate misinformation about the symptoms of depression. Their statements align with clinical discourse. However, they remain vague about the disease’s underlying causes and do not reflect upon how social structures might influence their mental life. The relationship between the vloggers and their audience is characterized by intimacy and mutual support. Regarding their identities, the vloggers present themselves as nurturing women who aim to combat stigma and assist viewers in overcoming their mental challenges. However, their personas are not strictly maternal; rather, they exude a more glamorous appearance with makeup and long eyelashes. As potential role models for their audience, they inadvertently contribute to the societal pressure of maintaining a flawless image, a pressure that has intensified in the era of social media. Notably, research consistently indicates that young women often grapple with negative body image, which frequently intersects with depression. In other words, the depression vlogs are potentially part of the problem they try to solve.
