Student Transition in Higher Education in Western Counties Revisited: Addressing and Mediating Challenges, A Holistic Approach
Authors: Athanasiadou Virginia , Lekka Eleni , Pilafas Georgios
Published: June 2024

Transitioning into Higher Education (HE) is the process whereby students take the plunge into the unfamiliar and engage in an entirely different context which triggers an array of concurrent changes, environmental, social, academic even financial. Transition is a matter of real importance to both individuals and institutions as unsuccessful transition means higher drop-out rates –currently averaging 40%. The paper first explores the theoretical underpinnings through the models of Tinto (1975)- linear perspective with emphasis on social assimilation, Nicholson (1990) - four-stage cyclical concept moving from preparation to stabilization - and Elander (2010) - introducing pedagogic practice. In the second part, challenges regarding suitable address are investigated. Challenges, being influenced by individual characteristics, social engagement, and pedagogic factors, need interventions which should be adequately customised to take account of all relevant dimensions. Different views of transition (induction, development or as being and becoming) are acknowledged, which may entail a different approach necessitating diverse courses of action. In this context, recommendations are outlined where all three perspectives are addressed. Academic: Pre-entry programmes with sufficient duration, offering assessment workshops, enhancing students’ epistemological beliefs, and developing realistic course expectations. Social: setting up social facilities, collaborative learning and teaching strategies, consistent support from staff. Personal: self-empowerment work, drawing upon older graduates lived experience. Taking a comprehensive, holistic approach and engaging the whole of the student rather than the part could potentially change the scene and produce more positive outcomes.

Effect of Ammonium Peroxydisulphate (APS) Addition on Polyaniline Nanofiber Microstructure in Interfacial Polymerization Method
Authors: Ketut Umiati Ngurah Ayu , Azam Muchammad
Published: June 2024

Synthesis of polyaniline nanofiber has been carried out using interfacial polymerization method. Polyaniline nanofiber was a material of interest for biosensors because this material was capable and effective as a mediator for electron transfer in redox and enzymatic reactions. The surface morphology of polyaniline nanofiber was much wider than conventional polyaniline, resulting in the process of molecular diffusion into the polyaniline nanofiber structure being faster and the penetration of molecules deeper, thus having the potential to increase the sensitivity and responsiveness of a sensor.
The interfacial polymerization method used includes a water phase (dopant, initiator and aquadestilate) and an organic phase (toluene as an organic solvent and aniline monomer). Based on the experiments that have been carried out, a relationship was obtained between the molar ratio of aniline and ammonium peroxy disulphate (APS). An indication of the adding effect of initiator can be seen through the morphology and functional groups of the polyaniline produced.
The experimental results showed that the diameter of the polyaniline nanofibers formed was observed to be larger when APS was added as an initiator. The diameter of polyaniline with the percentage of addition APS to aniline of 25%, 33% and 50% is (72.7 ± 0.8) nm, (68.9 ± 0.9) nm and (67.7 ± 1.3) nm, respectively. FTIR results indicate that polyaniline is in a semi-oxidation state and is in the form of emeraldine salt. The main characteristics of polyaniline nanofiber are characterized by the presence of N-H stretching modes (3356-3460 cm-1), C = N (1548-1571 cm-1) and C = C (1482-1489 cm-1) for quinoid and benzenoid rings as well as stretching modes C-N (1207-1363 cm-1) for the benzenoid ring. The degree of polyaniline oxidation increases with increasing quinoid/benzenoid ring ratio.

Authors: Kumala Dian Ardian , Fahmi Idqan , Hanan Sufrin
Published: June 2024

This research aims to analyze the factors that influence the quality of remote audits carried out by the XYZ Certification Body during the emergency period of the Covid 19 pandemic. Researchers try to identify the extent to which remote audits carried out can influence the quality of the audit itself by analyzing the variables involved. The emergency pandemic period is the right momentum to implement a new method of auditing which is carried out massively using a long-distance method between the auditor's location and the auditee due to a large-scale social restriction based on government policy. This research uses quantitative methods with primary data collected through questionnaires to selected organizations as well as secondary data from company reports, with output analysis of the influence between independent and dependent variables moderated by remote audit as a moderator variable, using the SEM PLS 4 tool so that its significance can be determined of these variables. From this research it can be concluded that remote audits do not have a significant effect on reducing audit quality and it is hoped that this activity can be used as an option in the future to be carried out either fully remotely or in a hybrid scheme. The managerial implication of this research is the need to develop auditor competency by carrying out regular training, involvement of Certification Body in calibrating auditor capabilities and the use of information technology and computer-assisted audit techniques which are useful tools for auditors and auditees to support the implementation of this activity.

Authors: Sekhar. P Chandra , Naveen Akula
Published: June 2024

Insomnia is one of the most common sleep disorder with a prevalence rate of 20-30% worldwide. Insomnia is a condition of unsatisfactory quality and/or quantity of sleep, with difficulty falling asleep, remaining asleep, or waking early and being unable to return to sleep. Factors like stressful life events, changes in work shifts, night watching, smoking, alcohol drinking and other mental disorders are the common predisposing factors which are leading to sleeplessness commonly in youngsters and middle-aged people. As use of sedatives may lead to dependency, impaired memory etc., so the Homoeopathy has a good scope in sleep disorders with minimal effects. Passiflora Incarnata is one of the frequently used remedy in Homoeopathy for insomnia. Its use in sleep disorders have been dated back to ancient periods. From ancient times in India, Africa, Europe, Turkey, America, Brazil, Iraq, Poland etc. it was used as traditional medicine for inducing sleep i.e., as a hypnotic. It is indicated for sleeplessness arising from exhaustion, over work, mental worries. As the above mentioned factors are frequent causes for sleeplessness now a day, Passiflora incarnate has been selected as medicinal intervention. This study aims at establishing the effectiveness of Passiflora Incarnata mother tincture in treating insomnia. This research is an experimental research having no control group with a sample size of 20 between the age group of 25-50 years. Those participants in the study sample who were meeting the criteria according to Athens Insomnia Scale (AIS) were diagnosed as insomniac. A cut-off score of greater than or equal to 6 on the AIS is used to establish the diagnosis of insomnia. The same scale (AIS) was used to assess the results after taking the medicinal intervention. The results showed that the Passiflora Incarnata mother tincture medicine is effective in treating insomnia.

Helicobacter Pylori Associated Gastritis: Case Series
Authors: S L Adithya , S Dharan Shaiju , Babu Bincy
Published: June 2024

Helicobacter (H. Pylori) infection is a common habitual infection responsible for upper gastrointestinal symptoms such as indigestion, abdominal pain, spewing, heart burn, and abdominal wholeness along with nausea and vomiting [1]. H Pylori is a mortal pathogen. The primary complaint associated with this infection is habitual active gastritis. The inflammation can lead to peptic ulceration and atrophic gastritis in a considerable number of infected subjects. A minority eventually develops gastric cancer or tumour. The threat of similar complications depends upon the inflexibility of gastritis, which is determined by various host and bacteria related factors. Among bacterial factors, the common one is the cagA pathogenicity, the presence of which has been associated with more severe gastritis, peptic ulceration, atrophic gastritis and gastric cancer [2]. Among the host factors, most of the evidence focuses on acid production in response to H. Pylori infection. To confirm the pathogenic part of H. Pylori, both the existent’s histological features of habitual gastritis and topographical patterns must be shown to be caused by the infection. Surface epithelial degeneration is a probable result of direct tissue injury by bacteria. Here are four intriguing cases of H. Pylori positive patients who had different admission presentations and were successfully treated with first line remedy and salvage remedy.

Production Planning Models (Approaches) from the Perspective of Mathematical Sciences
Authors: Tutiarny Naibaho
Published: June 2024

Introduction: This study aims to provide a mathematical description of the production planning model (method). There will occasionally be restrictions on the raw material availability for production activities due to this element of uncertainty.
Objectives: The researcher will outline and analyze the various perspectives, arguments, and opinions that exist in the literature, and look for relationships between them
Methods: This research was compiled using qualitative research methods and descriptive and analytical journal literature review approaches. Most of the data used are secondary data.
Result: Deterministic and stochastic mathematical models are the two broad categories into which production planning mathematical models fall. In deterministic models, the data is assumed to be confident at this point. In the meantime, the stochastic model uses data that reflects the "best prediction" of unknown values. These deterministic methods finally address average or worst-case value issues even though many human judgment and quantitative models have been developed to anticipate variables with this uncertainty. Even though they have been studied extensively in the literature, deterministic production planning models are generally not helpful when uncertainty is considered. There are two types of manufacturing-related uncertainties: system uncertainty and manufacturing environment uncertainty. The second category consists of supply and demand uncertainties and other uncertainties outside the purview of production process management.
Conclusion: Even though they have been studied extensively in the literature, deterministic production planning models are generally not helpful when uncertainty is considered. There are two types of manufacturing-related uncertainties: system uncertainty and manufacturing environment uncertainty. Uncertainties like supply and demand issues outside the purview of industrial process management are included in the second category.
An Analysis of Cyberbullying in Text Data using Deep Learning Algorithms
Authors: M. Dharani
Published: June 2024

Cyberbullying is a peculiarity that unfavorably affects individuals; its casualties experience a scope of emotional wellness issues, including low confidence, uneasiness, forlornness, and sorrow. Cyberbullying is become more normal while online entertainment use is turning out to be more inescapable. Regular procedures to battle cyberbullying include the utilization of rules and guidelines, human mediators, and boycotts that rely upon hostile language. These strategies, however, are not scalable and perform poorly in social media. To automatically identify cyberbullying behaviours, a principled learning system must be created. Nonetheless, the process is difficult because of the brief, chaotic, and disorganised content material, as well as the deliberate obscuring of offensive phrases or words by those who use social media. We suggest using sentiment data to identify cyberbullying behaviours in social media by putting forth a sentiment-informed cyberbullying detection framework. Our approach has been inspired by sociological and psychological research on bullying behaviours and their relationship to emotions. Experiments conducted on two publicly accessible real-world social media datasets demonstrate the advantages of the suggested approach. Additional research confirms that using sentiment data to detect cyberbullying is beneficial.
Comparative Analysis of Fuzzy Dagum Hazard Function Approaches for Estimating Failure Rates
Authors: Vidya P
Published: June 2024

When analysing the maintenance plan for a manufacturing system, the number of failures is a crucial consideration. There are frequently some uncertainties that have an impact on this number. The category of probabilistic uncertainty is distinct from probabilistic uncertainty, which encompasses most uncertainties. By using the fuzzy theoretical framework, this uncertainty is frequently modelled. With a fuzzy shape parameter, the failure numbers of the Dagum system under study in this paper is exhausted to calculate several failures.Here, the figure is computed via two distinct approaches. With the first approach, the quality of failure receives the exact same membership values based on fuzziness of DGM shape parameter.  To determine membership, using level of α-cut of the shape parameter approach and estimate formula for failure number from the second method. For the Dagum shape parameter, we employ the Triangular Fuzzy Number (TrFN) without losing generality. We demonstrate that both approaches were successful in calculating the failure rate. When we deliberate failures as an operating time, both methodologies show that as time increases, the ambiguity (or fuzziness) of the various failures that arise rises.The failure numbers that result as using the first method has a TrFN form. The second method's output failure rate, however, has a TrFN-like form rather than necessarily having a TrFN form. The Generalised Mean Value Defuzzification (GMDF) method is used to compare some aspects of these two approaches. The results reveal that the focal point of these fuzzy numbers of failures of corresponding DGM (Dagum distribution) are the same for any given GMDF weighting factor.

Fixed Point Theorems in Revised Fuzzy Metric Space via R_F-Contraction
Authors: Parakath Nisha Bagam P
Published: June 2024

The aim of this paper is to introduce a new type of contraction called contraction. As compared to the F-contraction in the existing literature, our contraction is much simpler and more straightforward, since it contains only one condition that is, the function revised fuzzy is strictly non-increasing. Moreover, some fixed-point theorems for contraction are presented. Further, some examples are given to illustrate its validity and superiority. In addition, by applying a very significant lemma, we show that our proofs of most fixed-point theorems are shorter and more elegant than ones in the literature.

IoT network traffic classification is an approach used to analyze IoT network traffic, revealing various network activities. The network traffic analysis process involves several steps: data input, preprocessing, feature extraction, classification, and performance analysis. Although various machine learning algorithms have been proposed in recent years, they have failed to achieve high accuracy and effectively extract features from datasets. This research aims to develop an algorithm that can extract features and achieve high accuracy in network traffic classification.To accomplish this, a hybrid optimization algorithm combining genetic algorithms and Particle Swarm Optimization (PSO) is proposed. This hybrid algorithm extracts features, which are then classified using Random Forest. The proposed model is implemented in Python, and its performance is evaluated in terms of accuracy, precision, and recall.

Published: June 2024

Agricultural products, fruits, and vegetables, can be of varying quality. Proper sorting and grading of these products are essential in national and international trade, hence the country's socioeconomic development. Currently, most agricultural sectors depend on the manual sorting of products, which is tedious and inaccurate. This paper addresses this issue by designing an IoT-based fruit sorting system using transfer learning. It uses a transfer learning-based classifier to identify the input fruit class. The fruit to be classified passes through a conveyor belt. The digital camera interfaced with the classifier takes the fruit image and gives it to the classifier network. The classifier network is a predesigned model trained using the fruits to be classified. The result of the classifier couples to a microcontroller-based system. Based on the type of the classified fruit, the microcontroller activates the piston system connected to the conveyor belt. The collecting boxes placed near the conveyor belt-piston arrangement contain the sorted fruits. A microcontroller-based system monitors the collecting box status. The sensor attached to the box sends signals regarding its status, whether full or not. If the box is 80% full, the microcontroller alerts that box overflow can be avoided. The box status is updated on the concerned website using a cloud system for further procedure.

The source of income and livelihood of around 70% of the Indian population depends on agriculture.  Agriculture plays a significant role in the Indian economy. However, an exploding global population, a changing climate, global warming, soil pollution, rapid urbanization, and the exhaustion of arable land, among other issues, have harmed agriculture production and its dependents in India. Available cultivable land is decreasing yearly, and current food production using traditional farming practices will not be enough to feed millions of people in the coming days. There is a pressing need to revolutionize our agricultural and horticultural practices using advanced technologies like IoT, AI, cloud computing, data analytics, blockchain, etc.
In this study, we have presented a three-layered Internet of Things (IoT) architecture appropriate for horticulture production and conducted a Systematic Literature Review (SLR) to demonstrate the extensive research accomplished in various application domains of IoT and Artificial Intelligence (AI) concerning horticulture production cycle. In addition, we have discussed challenges and open issues in deploying IoT to horticulture from a three-layered perspective. Further, we differentiated existing research accomplished in the key application areas of IoT and AI concerning the horticulture production cycle. This article identifies key research areas that should be investigated, thereby assisting researchers, industry experts, and academicians in investigating open issues.
