The Social Satire in Swift’s Gulliver’s Travels
Authors: Asst. Prof. Dr. Haseeb Alias Hadeed Asst. Prof. Dr. Haseeb Alias Hadeed
Published: May 2024

ABSTRACT
In Gulliver's Travels (1726) Swift presented different kinds of satire. These different kinds of satire divided the critics into groups with different points of view concerning the satirical tendencies in Gulliver's Travels. Swift  concentrates on the inside of things rather than the outside; on actuality rather than illusion . It is important to note that Swift seized all the opportunities so as to direct his severe attack on different aspects of life.    In Gulliver's Travels, there is emphasis laid on man's bad nature and his social role. His recognition of the defects in human nature leads him to depict human nature. Therefore, he presents the Yahoos as an embodiment of all the well-known human vices and follies. So, he ruthlessly satirizes bad elements in man's nature over which man has a full control. He believes that man is capable of keeping them under his control.

Abstract
This study aims at revisiting the forms and functions of vocatives in English. Vocatives can be classified into different forms that perform two main functions in English viz, calling the addressee and maintaining the relationship, the former labeled as the identification function while the latter as the expressive function. The various forms of vocatives vary in fulfilling both functions. In addition, the expressive function of vocatives is governed by some factors such as the addresser, the addressee and the context or the situation in which the vocatives can be used.

Humanisme Islam Nusantara dan Kontribusinya Bagi Dunia
Authors: Kolek Deodatus
Published: May 2024

The term ‘Islam Nusantara’ (Archipelagic Islam) has been used not only to cover the Indonesian territory but also the neighboring countries. The term contains humanistic values and humanism, people in humane face, tolerance and moderate. All this reflects Islam as religion of peace. Besides it could contribute for promoting humanistic values as well as peace in the world.Such humanistic appearance of ‘Islam Nusantara’ adapts local genius of the country and highly regarded traditions of the local peoples before the coming of Islam. This accommodation could avoid any kind of both physical and verbal violences from the society and keep the people away from any possible harmful act toward their neighbour.

Authors: Simamora Chandra Susilo
Published: May 2024

Indonesia is a plural society, particularly in the religious aspect. It is very prominent all over the Indonesian islands and cities, including the city of Malang. Plurality in religion of this city, on the one hand, contributes for the richness of living together besides its differences. On the other hand, it brings forth some problems, particularly the issue of majority-minority relationship. For bridging the gap, the Catholic Church of the Diocese of Malang has always been promoting interreligious dialogue with people of other faiths. The writer reflects this bridge-building in the light of Jacques Dupuis’ theology of dialogue and Trinitarian Christology that may enrich the practice of interreligious dialogue throughout the city.
Eksorsisme dalam Perspektif Gereja Katolik
Authors: Herianto Tjatur
Published: May 2024

.Artikel tersebut menjelaskan bahwa praktik eksorsisme di Gereja Katolik sangat jarang terjadi. Namun, ketika kehadiran Setan atau Iblis muncul dengan jelas dalam menyerang kehidupan manusia dan merusaknya secara fisik, dianggap dapat diterima bahwa pengusiran setan harus dilakukan. Penulis berpendapat bahwa di Gereja Katolik setiap kasus eksorsisme harus melalui pemeriksaan yang cermat dan ekstra. Seorang pengusir setan juga harus mengikuti peraturan Gereja yang ketat dan dilengkapi dengan pelatihan khusus; jika tidak, dia dapat dikenakan sanksi berat. Di sisi lain, Gereja harus tetap waspada untuk menghadapi setiap kekuatan gelap dengan iman Kristen dalam kuasa Yesus Kristus serta rasionalitas dunia modern kita saat ini.

ASSESSING THE EFFECT OF CHATBOTS ON MANAGING BRAND REPUTATION AMONG COMMERCIAL BANKS IN MALAYSIA
Authors: Hilmi Muhammad
Published: May 2024

Commercial banks in Malaysia are facing increasing competition from non-bank financial institutions, such as mobile money operators and microfinance institutions. To maintain their market share and reputation, banks need to find ways to improve customer service and engagement. Traditional customer support channels may be insufficient to meet the evolving expectations of tech-savvy customers in a digitally driven era. The reliance on manual customer service processes, which can be time-consuming and prone to human error, may lead to delayed response times, inconsistent messaging, and inadequate handling of customer inquiries and complaints. This can negatively impact brand reputation, as customers value prompt and accurate support experiences. The objective of this study was to assess the effect of chatbots on managing brand reputation among commercial banks in Malaysia. This research was based on the communication accommodation theory and the technology acceptance model to explain the relationship between the study variables. A descriptive survey design was adopted. The target population included the 26 commercial banks operating in Malaysia.  A census was conducted on all the 26 commercial banks. The unit of observation was the brand managers and communication managers in each of the commercial banks. Primary data was collected through structured questionnaires. The study reveals a strong positive correlation between the effective integration of chatbots and the management of brand reputation in commercial banks in Malaysia. The regression analysis further confirms the significant impact of chatbots on brand reputation, emphasizing their role in shaping favorable customer perceptions. The study concludes that as banks prioritize the seamless implementation of chatbots, they can enhance customer service experiences, contributing to a positive brand image. To leverage this potential, recommendations include refining chatbot efficiency to address perceived response time, investing in ongoing training, and monitoring interactions to strike a balance between automation and personalized service, thereby ensuring sustained and improved brand reputation in the competitive financial sector.

An Investigation of Aerodynamic Noise from Standard Ground Vehicles using Computational Aeroacoustics
Authors:   , Chode Kushal Kumar
Published: May 2024

The noise radiating from ground vehicles and its detrimental effects on occupants, pedestrians, and the environment have spurred vehicle manufacturers to seek effective noise prediction methods and mitigation strategies. This thesis focuses on predicting aerodynamically generated noise from vehicles using a hybrid Computational Aeroacoustics (CAA) method. This study aims to explore how geometrical features influence noise generation and provide valuable insights for noise reduction. A hybrid CAA approach is proposed, employing Stress Blended Eddy Simulation (SBES), and Ffowcs-Williams and Hawkings (FW-H) acoustic analogy to predict noise radiation from standardised vehicle geometries. Initially, SBES is validated against experimental data for scaled notchback geometry, followed by assessing SBES coupled with FW-H to predict noise radiated by half-round mirrors. Subsequently, the methodology is applied to full-scale vehicle geometry with a bluff mirror mounted on one side. The SBES predictions indicate that the flow behaviour behind the backlight of notchback becomes increasingly asymmetric with a higher backlight angle, which is consistent with the experimental findings. As the backlight angle increased, the strength of the vortex generated from the lateral edges of the backlight decreased on one side and increased on the other side, leading to an asymmetrical flow. The hybrid CAA approach predicts the flow and noise radiated from the half-round mirror in agreement with experiments and reveals increased noise radiation with higher aspect ratios but reduced noise when the mirror is inclined towards the mounting plate. Notably, the radiated noise from the half-round mirror exhibited a dipole-like structure near the plate and a monopole-like structure away from it. This observation is consistent for both variations introduced into the half-round mirror. For the full-scale vehicle model, the absence of the A-pillar is identified as the primary contributor to overall noise radiation. However, in the presence of a side-view mirror, the side window becomes a significant contributor to noise. Additionally, when the mirror is inclined, a linear reduction in the radiated noise is observed, although the vehicle's overall drag becomes nonlinear and highly dependent on the flow behaviour past the mirror. The proposed hybrid CAA approach provides valuable insights into noise prediction for ground vehicles. By considering the impact of mirror inclination and geometric factors on noise radiation, this research contributes to the development of quieter and more aerodynamically efficient vehicles, thus fostering a comfortable and sustainable transportation environment.
Genetic trends and common BRCA1/2 pathogenic sequence variants in black African and Indian breast cancer patients presenting at Inkosi Albert Luthuli Central Hospital, KwaZulu-Natal, South Africa
Authors: Makhetha M , Aldous C , Chabilal N
Published: May 2024

Background. Hereditary breast cancer is characterised by the presence of a pathogenic sequence variant passed from one generation to the next. These cancers are aggressive, develop early, and account for 5 - 10% of all breast cancer cases. In South Africa (SA), the common variants that predispose to hereditary breast cancer have been well documented among white patients and form part of screening panels during targeted testing. For non-white patients, common variants are not well understood, and as such, all populations are offered the same test optimised for white patients. This carries a risk of misdiagnosis, the consequences of which include recurrence and increased mortality.
Objectives. To retrospectively describe genetic trends in the black African and Indian breast cancer patients from KwaZulu-Natal Province, SA.
Methods. We reviewed clinical and genetic data of breast cancer and high-risk patients who consulted at Inkosi Albert Luthuli Central Hospital between 2011 and 2021. Inclusion criteria were based on clinical and demographic characteristics as defined by SA clinical guidelines.
Results. Black African patients were young (mean 37.6 years, standard deviation 11.16) and had the majority of triple-negative tumours (37.5%). Indians represented 50% of bilateral breast cancers and of high-risk individuals. We identified 30 pathogenic BRCA1/2 sequence variants, four large genomic rearrangements and 13 variants of unknown significance. Twenty black patients carried 12, 13 white patients carried 4, 25 Indian patients carried 16, and 3 coloured patients carried 3 pathogenic sequence variants. The most frequent variants were BRCA2 c.5771_5774del, p.Ile1924fs among black patients, BRCA2 c.7934del, p.Arg2645fs among white patients, and BRCA2 c.8754+1G>A among Indian patients. None of the founder mutations common in white patients was reported in either black, Indian or coloured patients, which explains why black, Coloured and Indian SA patients consistently test negative during targeted screening.
Conclusion. This study highlights unique genetic trends for SA populations and the need for more inclusive targeted tests that are optimal for these populations.
The antimicrobial susceptibility patterns of diabetic foot ulcers in the South African public healthcare sector
Authors: Turner M J , Leigh-de Rapper S , Mokoena T P , Van Vuuren S
Published: May 2024

Background. Diabetic foot syndrome is defined as the presence of a diabetic foot ulcer (DFU) associated with neuropathy, peripheral artery disease and infection. While the use of antimicrobials in the treatment of DFU infection remains a mainstay, the choice of antimicrobial remains problematic owing to the presence of multidrug-resistant polymicrobial infections. In the South African public healthcare sector, the treatment of DFUs is based on the Standard Treatment Guidelines (STGs) and the Essential Drug List. These guidelines are developed using evidence-based medicine and are based on global susceptibility patterns rather than local susceptibility data, and may not provide the most appropriate treatment options.
Objectives. To determine the antimicrobial susceptibility patterns of DFUs isolated from patients visiting selected Gauteng provincial public hospitals in order to determine a clinically effective treatment protocol for the management of these infections.
Methods. Sample swabs were taken from 51 DFUs using the Levine method. Each sample swab was spread onto blood agar plates, and thereafter individual pathogens were isolated. The antimicrobial susceptibility patterns of all isolated pathogens were determined using zone of inhibition measurements. Pathogens were grouped according to macromorphological characteristics as well as susceptibility patterns, and a representative isolate from each group was then identified.
Results. A total of 51 DFU ulcer swabs from 45 patients were included in the study. From the sample swabs, a total of 445 pathogens were isolated. The most effective antimicrobial was found to be gentamicin, followed by ciprofloxacin. Amoxicillin/clavulanic acid, the first-line treatment according to the STGs, was found to be ineffective for many of the isolated pathogens. The most commonly isolated pathogens were Proteus mirabilis, Enterococcus faecalis and Pseudomonas aeruginosa.
Conclusion. These findings demonstrate the urgent need to reassess the STGs and base treatment plans on local epidemiological data. This study provides valuable data on common causative pathogens in DFU infections, as well as the resistance patterns of these pathogens, forming a baseline on which to base future DFU treatment plans.

Visual working memories are abstractions of percepts
Authors: Duan Ziyi , Curtis Clayton E
Published: May 2024

During perception, decoding the orientation of gratings depends on complex interactions between the orientation of the grating, aperture edges, and topographic structure of the visual map. Here, we aimed to test how aperture biases described during perception affect working memory (WM) decoding. For memoranda, we used gratings multiplied by radial and angular modulators to generate orthogonal aperture biases for identical orientations. Therefore, if WM representations are simply maintained sensory representations, they would have similar aperture biases. If they are abstractions of sensory features, they would be unbiased and the modulator would have no effect on orientation decoding. Neural patterns of delay period activity while maintaining the orientation of gratings with one modulator (e.g. radial) were interchangeable with patterns while maintaining gratings with the other modulator (e.g. angular) in visual and parietal cortex, suggesting that WM representations are insensitive to aperture biases during perception. Then, we visualized memory abstractions of stimuli using models of visual field map properties. Regardless of aperture biases, WM representations of both modulated gratings were recoded into a single oriented line. These results provide strong evidence that visual WM representations are abstractions of percepts, immune to perceptual aperture biases, and compel revisions of WM theory.
An Autopsy Case of Calcific Aortic Valve Disease in Sudden Death of a Young Man
Authors: Kim Jae-Hui , Park Jihyun , Lee Sang Won , Lee Jong Kyu , Yeo Nam Seok , Lee SangHan
Published: May 2024

Calcific aortic valve disease (CAVD) is an uncommon disease in young adults, unless there is a congenital anomaly in the aortic valve. We report a case of CAVD identified during the autopsy of a 26-year-old male soldier who died in his room while sitting on a chair. Macroscopic examination revealed multiple nodules in the semilunar cusps of the aortic valve, and that the commissure of semilunar valve cusps was slightly fused. Under microscopic examination, fibrotic nodules with neovascularization were identified in the fibrosa layer of the aortic valve, although neither calcification nor chronic inflammation were identified in the fibrotic nodule. Mitral valve prolapse and left ventricular hypertrophy with interstitial fibrosis were also identified. Microscopic examination of CAVD typically shows calcified nodules in the fibrosa layer of the valve, but fibrosis alone, without calcification, can be observed in the early stage of the disease. Death from CAVD is rare in young adults, so careful examination must be taken not to misdiagnose this condition with rheumatic valvular disease, which is relatively common in this population.

Published: May 2024

Portable devices like accelerometers and physiological trackers capture movement and biometric data relevant to sports. This study uses data from wearable sensors to investigate deep learning techniques for recognizing human behaviors associated with sports and fitness. The proposed CNN-BiGRU-CBAM model, a unique hybrid architecture, combines convolutional neural networks (CNNs), bidirectional gated recurrent unit networks (BiGRUs), and convolutional block attention modules (CBAMs) for accurate activity recognition. CNN layers extract spatial patterns, BiGRU captures temporal context, and CBAM focuses on informative BiGRU features, enabling precise activity pattern identification. The novelty lies in seamlessly integrating these components to learn spatial and temporal relationships, prioritizing significant features for activity detection. The model and baseline deep learning models were trained on the UCI-DSA dataset, evaluating with 5-fold cross-validation, including multi-class classification accuracy, precision, recall, and F1-score. The CNN-BiGRU-CBAM model outperformed baseline models like CNN, LSTM, BiLSTM, GRU, and BiGRU, achieving state-of-the-art results with 99.10% accuracy and F1-score across all activity classes. This breakthrough enables accurate identification of sports and everyday activities using simplified wearables and advanced deep learning techniques, facilitating athlete monitoring, technique feedback, and injury risk detection. The proposed model’s design and thorough evaluation significantly advance human activity recognition for sports and fitness.

Published: May 2024

Purpose: This study aimed to evaluate the effects of auricular acupressure on the severity of urinary incontinence, quality of life, and sleep quality in elderly women with stress urinary incontinenceMethods: This single-blind, randomized, placebo-controlled study included 53 subjects. The participants were elderly women with stress urinary incontinence. The experimental period was a total of 6 weeks, and four different acupressure sites were applied for each group; the experimental group (n=27) received auricular acupressure on the kidney, bladder, central rim, anterior lobe, whereas the placebo-control group (n=26) received acupressure on the wrist, elbow, helix 2, and helix 3. In order to examine the effects of the auricular acupressure intervention, the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF), Incontinence Quality of Life (I-QOL) and Pittsburgh Sleep Quality Index (PSQI) were measured before and after the intervention.Results: The ICIQ-UI SF scores and the PSQI scores in the experimental group with auricular acupressure significantly decreased after 6 weeks (p<.001) compared with the scores of the placebo-control group. The I-QOL scores in the experimental group significantly increased after 6 weeks (p<.001) compared with the scores of the placebo-control group.Conclusion: Auricular acupressure was effective for mitigating the severity of urinary incontinence and improving the quality of life and sleep after 6 weeks. Therefore, auricular acupressure can be used as a non-pharmacological nursing intervention for elderly women with stress urinary incontinence.

La agenda de investigación de las comunicaciones es probablemente una de las más desafiadas por los vertiginosos cambios del espacio mediático, especialmente en el campo digital, en el que las nuevas interacciones y agencias ocurren en el marco de la globalización tecnológica y de la economía de la información algorítmica. En camino al fenómeno de lo que Casilli y Posada (2019) denominan la plataformización del trabajo y de la sociedad, con resultados aún inciertos, en octubre de 2022 se efectuó la compra de Twitter por 44.000 millones de dólares (Conger & Hirsch, 2022). Hasta entonces, esta plataforma de microblogging de acceso abierto era usada en gran medida como un instrumento de información esencial por distintos medios y, como afirma Vergeer (2015), era un recurso relevante de comunicación política.

Considering the importance of soil and foundation in the construction of engineering structures, it is important to investigate the bearing capacity of engineering soils. The purpose of this study was to examine the soils' carrying capacity in southwest Nigeria's Ife-East Local Government Area. Samples of soil were taken from a few chosen construction sites in the research region. Preliminary and geotechnical tests, including triaxia, Atterberg limits, specific gravity, natural moisture content, and particle size measurement, were performed on the soil samples using standard protocol. The bearing capacity of the soil samples was computed for different footing types (circular. square and strip footings) using Terzaghi’s bearing capacity equations. Results showed that all the soils fell into A-2-4 group, according to American Association of State Highway and Transportation Officials (AASHTO) classification standard. Also, using Unified Soil Classification System (USCS), it was observed that 75 % of the samples were well-graded sand (SW) and 25 % were poorly graded sand (SP). For square footing, the bearing capacity values ranged from 269.12 KN/m2 to 3340.85 KN/m2; for circular footings, the values ranged from 267.90 KN/m2 to 3313.47 KN/m2; and for strip footings, the values ranged from 221.58 KN/m2 to 2700.54 KN/m2.
It was concluded that all the tested samples were c-ɸ soils, and all the soils could be described as excellent to good foundation materials. The study confirms the fact that the values of bearing capacity are influenced by the nature of foundation soil and shape. and circular footing was found to have intermediate magnitude in all cases.

Wheat (Triticum aestivum L.) is one of the major crop grown in about all part of the world. In Pakistan wheat  is one of the major cash crop. In Pakistan Punjab  province is the major producer of high quality wheat crop. Wheat are attacked by many different pathogen  including Bacterial , Viral and fungal pathogens and they cause a great losses in yield and quality of wheat . Specially the Brown rust which caused by Puccinia triticina is one of the major disease attacking wheat crop  in open field. The aim and objective of this study is to determined the efficacy of different fungicide which are mostly used in Pakistan and study which fungicide is  most efficient against brown rust of wheat. This experiment was conducted at Plant Pathology Research Institute, Ayub Agricultural Research Institute, Faislabad, Pakistan . Experiment was laid out in RCBD in 3Replication . And the wheat variety which is used for this study is Akbar-19. Which is the most popular and widely growing variety in Punjab Pakistan . The commonly available and widely used Fungicide I.e Tilt, Amistar top, Belanty, Epic are used in this experiment to check which one is more efficient. Tilt fungicide shows great result against brown rust.
Impact of Posterior Pericardiotomy on Prevention of Post Operative Atrial Fibrillation in Patients Undergoing Coronary Bypass Surgery

Purpose: Coronary artery bypass grafting surgery (CABG) is a common surgical procedure used to treat coronary artery disease (CAD). Despite advancements in the surgical techniques and perioperative care, cardiac surgery patients remain at risk of developing complications, especially atrial fibrillation (AF), The present study aimed to investigate the impact of posterior pericardiotomy on the incidence of postoperative AF and other relevant complications following CABG.
Methods: This study is a randomized controlled trial conducted at a single center. A total of 204 patients were randomly assigned to two groups: the pericardiotomy group and the non-pericardiotomy group (control group). The study assessed the incidence of postoperative atrial fibrillation within the first 7 days following CABG surgery.
Results: Our findings revealed no statistically significant difference in the incidence of pericardial effusion and AF between the pericardiotomy and non-pericardiotomy groups. The lack of cardiopulmonary bypass (CPB) in the on-pump CABG method may have contributed to the absence of significant differences in pericardial effusion rates between the groups. Moreover, we found that posterior pericardiotomy did not significantly affect the intubation time, length of stay in the intensive care unit (ICU), and total hospital stay in either group. Our study differs from previous research that focused on off-pump CABG patients. Studies that utilized CPB reported a significant reduction in pericardial effusion and arrhythmias with posterior pericardiotomy. This discrepancy suggests that the use of CPB may play a crucial role in the occurrence of arrhythmias and subsequent complications.
Conclusions: our study indicates that posterior pericardiotomy did not significantly influence the incidence of pericardial effusion and AF in on-pump CABG patients. Considering the differences in surgical techniques and patient populations, further research with larger sample sizes is warranted to provide more definitive insights into the role of posterior pericardiotomy in this specific setting. Comprehensive studies will be instrumental in guiding clinical decisions and establishing best practices for the prevention of postoperative pericardial effusion and arrhythmias in on-pump CABG patients.

This research outlines into exploring the genetic variability, heritability, and genetic advance among 33 diverse lentil genotypes for 11 quantitative traits in the rabi season of 2022-2023 in Punjab, India. Three replications of each of the 33 genotypes of lentil were planted in a randomized block design. The Analysis of Variance was found significant for all the traits under study, this implies that a significant amount of variation is present among these genotypes. The estimates of PCV and GCV were found to be moderate for most of the traits under study. Heritability estimates ranged from 96.80% to 45.08%, with a high heritability observed for traits like Days to maturity, No. of primary branches per plant, No. of secondary branches per plant, seed yield per plant, No. of pods per plant, Biological yield, No. of seeds per pod, Harvest index, and Day to 50% flowering. The traits with the highest estimates of genetic advance included Seed yield per plant, No. of primary branches per plant, No. of secondary branches per plant, and No. of seeds per pod. The study identified a significant genetic variability among the lentil genotypes, characterized by high heritability and genetic advance for key traits such as Seed yield per plant, No. of primary branches per plant, No. of secondary branches per plant and No. of seeds per pod. These results point towards the presence of additive gene effects influencing the inheritance of these traits, highlighting the efficacy of simple selection methods for enhancing lentil quality focusing on these essential agronomic characteristics.
