Y. Patil Medical College, Pimpri, Pune in between September 2020 to July 2022. The patients were given a brief explanation of the procedure before the commencement of the CT scan. Patients with normal RFT and NBM status for a minimum of 4 hours were taken. A 128-section multidetector CT scanner is used to scan patients (Philips Medical Systems).</p> <p><strong>RESULTS:</strong> The total number of grafts assessed was 68 grafts. Out of which 25 grafts (36%) were arterial grafts and 43 grafts (64%) were venous grafts. Comparison of mean percentage stenosis of all venous grafts vs all arterial grafts were highly significant (p- value &lt;0.001) and arterial grafts had better graft patency than venous grafts. Graft occlusion was compared between symptomatic and asymptomatic patients using the Chi-square test which was highly significant (p-value &lt;0.001) and there was a positive correlation between symptoms and graft stenosis. The assessment of stenosis or occlusion of arterial bypass grafts on MDCT in comparison to ICA resulted in a sensitivity of 100%, specificity of 100% respectively. The diagnostic accuracy of MDCT is 100%. The assessment of stenosis or occlusion of venous bypass grafts on MDCT in comparison to ICA resulted in a sensitivity of 100%, specificity of 93.33% respectively. The diagnostic accuracy of MDCT is 96.83%. The graft stenosis percentages on CT were obtained. Grafts are graded as minimal, mild, moderate, and severe based on the percentage of stenosis. Total grafts with no stenosis (37 grafts), minimal stenosis (1 graft), mild stenosis (1 graft), moderate stenosis (5 grafts), and severe stenosis (24 grafts).</p> <p><strong>CONCLUSION:</strong> A direct correlation between symptoms and the degree of stenosis of grafts. As compared to arterial grafts, venous grafts had lower long-term patency. MDCT was found to be on par with ICA in the aspects of sensitivity, specificity, and diagnostic accuracy and due to the growing demand for faster scanning, reduced contrast agent use, and radiation exposure, as well as ongoing technological advancement, the MDCT will play an increasingly important role in the monitoring of CABG patients, CAD, and all other situations that call for a non-invasive, quick, and reliable diagnostic technique.</p> Dr. Aparna Shrikanth Prabhu , Dr. Tushar Kalekar , Dr. Suhas M , Dr. Shreeya Goyal , Dr. Akhil R Copyright (c) 2023 2022-12-31 2022-12-31 1 8 10.47750/pnr.2022.13.S10.01 Effect Of Room Temperature And Refrigerated Storage On Automated Hematological Parameters And Peripheral Blood Smear Examinations <p><strong>Background: </strong>Complete blood count and morphological assessment of peripheral blood smear examination are the most common investigations done in laboratory in order to give crucial information about disease and its final diagnosis. Blood samples are commonly sent from the clinical lab after an extended post-collection period. The laboratory must determine whether to accept or reject such a sample when it is delivered. If the specimen is approved, the laboratory must next choose whether to carry out all the tests requested or just those necessary, given the specimen's age and also choose what remarks should be added to the reported results reflecting the accuracy or limits of the analysis.</p> <p><strong>Aim: </strong>To evaluate the variation in hematological parameters on automated hematological analyzer and peripheral blood smear examination of samples stored at room temperature and samples stored at refrigerated temperature (2-8<sup>0</sup>C).</p> <p><strong>Materials and methods: </strong>Blood samples were collected from 60 patients. Hematological parameters like Hemoglobin, HCT, MCV, MCH, MCHC, Platelet count, red blood cell and White blood cell count were analyzed in room temperature storage and refrigerated storage at 2-8<sup>0</sup>C for 24 hours (30 samples each) using automated hematology analyzer. Peripheral blood smear from samples stored at room temperature and at 2-8<sup>0</sup>C in refrigerators for 24 hours were also examined.</p> <p><strong>Result: </strong>This study showed hematological parameters affected when stored at room temperature were RBC, HCT, MCV, MCH, MCHC, RDW and Platelet count. Hemoglobin and WBC Counts were not affected after 24-hour storage at room temperature. While at 2-8<sup>0</sup>C refrigeration, all the hematological parameters were stabilized and changes were not statistically significant. Morphological changes like crenated RBCs, increased size of platelet and vacuolated WBCs were seen peripheral blood smear examination.</p> <p><strong>Conclusion:</strong> This study emphasizes to assay hematological parameters and peripheral blood smear examination immediately after sample collection in order to prevent the misinterpretation of results. Standardized storage conditions reduce pre-analytical variation and the hematological parameters affected by storage and temperature in a way that could influence clinical decisions. Therefore, to provide an accurate report if there is a known delay in the interpretation of the sample, refrigeration of EDTA blood samples at 2-8<sup>0</sup> C is advised.</p> Dr. Yesha Parimalbhai Lad , Dr. Abhinav Shetty, Dr. Nirali Patel, Dr. Banyameen Iqbal, Dr. Charusheela Gore Copyright (c) 2023 2022-12-31 2022-12-31 9 17 10.47750/pnr.2022.13.S10.02 Splenic Artery Embolisation: An Institutional Case Series <p>Pancreatitis is one of the common causes of acute abdomen, with vascular complications being most dangerous life-threatening ones. They include formation of vessel thrombosis, erosion of vessel wall and formation of pseudo aneurysm due to release of activated pancreatic enzymes. Pseudoaneurysms most commonly affect the splenic artery, gastro-duodenal, pancreatico-duodenal, gastric and hepatic arteries. Rupture of this pseudo-aneurysms can be fatal due to massive bleeding. Hence prompt diagnosis and treatment of these lesions is necessary to prevent further catastrophe.</p> Dr. Vishal Nandkishor Bakare, Dr. Krishna Teja Nerella Copyright (c) 2023 2022-12-31 2022-12-31 18 26 10.47750/pnr.2022.13.S10.03 Role Of Diffusion Tensor Imaging And Diffusion Tensor Tractography On 3t Mri In Spinal Cord Lesions <p><strong>AIM:</strong> The aim of the study is to study the role of Diffusion Tensor Imaging and Diffusion Tensor Tractography on 3T MRI in spinal cord pathologies.</p> <p><strong>MATERIAL &amp; METHODS:</strong> A Prospective observational study includes 50 students at Padmashree Dr. D. Y. Patil Medical College and Hospital and Research Centre, Pimpri, over the period of 2 years in between September 2020 to November 2022. Patients with suspected spinal cord pathologies were subjected to MR Imaging of the spinal cord. Standard spine protocol (Sag T2 tse, Sag T1 tse, Cor T2 stir, Ax T2 tse, Ax T1 tse), DTI and DTT were done for all patients.</p> <p><strong>RESULTS:</strong> Out of 50 participants 23 were females (46%) and 27 were males (54%) &amp; majority of the patient belonged to age group of 31-40 years (26%). 13 patients were normal, and 9 patients had minimal disc bulges but no significant spinal canal stenosis/ indentation of the spinal cord. These 22 patients considered normal showed mean FA (0.69 +/- 0.01) and ADC values (0.88 +/- 0.09) which were similar at all disc levels. In the 15 patients showing significant spinal stenosis and normal appearing cord, statistically significant reduction in FA values and increase in ADC values were seen at levels C3-C4, C4-C5, C5-C6. 2 patients with syrinx, 2 patients with Hirayama disease, and 2 patients with long and short segment cord hyperintensity had significantly reduced FA and increased ADC values. DTT showed displacement of the white matter tracts ventrally in a case of spinomedullary junction astrocytoma.</p> <p><strong>CONCLUSION:</strong> DTI is a promising new tool which offers an insight on the pathophysiology and microstructural changes related to diseases of the spinal cord. DTI changes appear in normal appearing spinal cord in cases of cervical spondylotic myelopathy. This shows promise in detection, prognosticating and planning treatment in some neurosurgical disorders like CSM. More information is needed regarding the precision and dependability of DTI indices in classifying cord disease. To overcome limitations improvement and standardization of scanning procedures and image processing is necessary.</p> Dr. Suhas M , Dr. Purnachandra K Lamghare , Dr. Aparna Shrikanth Prabhu , Dr. Tushar Kalekar , Dr. Karthik M , Dr. Akhil R Copyright (c) 2023 2022-12-31 2022-12-31 27 36 10.47750/pnr.2022.13.S10.04 Customers Perception And Satisfaction Towards Technology Enabled Bank Services: An Empirical Study <p>“Banks play an important role in the economic development of a country.

While software team compositions have been researched based on tasks, personality, and role descriptions, few models exist to help software project managers’ reason about software teams with respect to culture. As more culturally diverse teams develop software products, software project managers need to manage teams based on cultural factors that will inevitably arise. This research examines the effect of culture on software project team management, and its impacts on software productivity, especially as it pertains to requirements engineering tasks. The main objective is to investigate how individuals from different cultures work together in software development projects, and to use that understanding to formulate a model for reasoning about key cultural factors.

As much as 70% more production efficiency is needed for all types of crops from the same land resources in order to meet demand without negatively impacting the environment. At the same time, one-third of our food is wasted. Other variables, such as global warming, more frequent storms, water shortages, and problems with soil and water stream contamination, which can result in waste and decreased output, might make it more difficult for farmers to fulfill the growing demand for crops for human and animal use. We evaluate a technology to help manage these problems. We examine a technology to help the agricultural sector, which will benefit both farmers and the general public by producing high-quality, safe food that satisfies both present and future demand, in order to control these difficulties. Smart farming, the Internet of Things, big data, high-performance computing, and cloud computing are all combined in the solution to provide precision agricultural services innovation that address real-world issues. The creating a solution with a data-driven applications will be facilitated by storing agriculture data on supercomputers. In soil and plant research, supercomputers store information from multiple sources, including sensors on the ground. It is possible to collect valuable operational information about soil quality, crop nutrients, forecasts of crop yields, the best harvesting time, gas emissions, and soil contamination through satellite and drone imagery. Through machine learning and artificial intelligence, the supercomputer also extracts crucial data and converts it into apps that are sent through different routes, with direct delivery to farmers' cell phones being the most convenient. In this paper we will be discussing about best practices we carry forward to implement a precision agriculture practice in India.</p> K.Vijesh , Dr. R.

Clustering faces several challenges in the Cluster head selection and the network’s optimal data routing. So, this paper presents an efficient clustering approach using hybrid Grey Wolf Optimization based multi-objective forest optimization algorithm (H-GWMFO) approach to shorten the distance at which sensor nodes in wireless sensor networks transmit data, which offers energy-efficient clustering and the best data routing to increase the longevity of the network. The cluster head selection was performed by the grey wolf Optimization, followed by the Multi objective Forest optimization that enhanced the CH on the basis of Energy, Euclidian distance, trust, and delay of the sensor Nodes. When compared to the well-known cluster-based protocol created for WSNs, like WOA, GWO-DNN, RF, and the K-means with GWO methods in MATLAB for Delay, Energy consumption, Packet Delivery Ratio, Throughput and Network Lifetime of the proposed protocol's performance is evaluated.

The distribution of the service life of residential buildings, the function of their reliability and the distribution of depreciation of the buildings under study are interdependent concepts. The deterioration of the object will be the higher, the longer the period of its operation. However, this is not an increase that reflects the life span of the building, nor is it a cost that is directly proportional to its age. The article presents a model and methodology for checking the level of deterioration and reliability of MAB, operated in different regions of the Republic of Uzbekistan, built in the period 1967-2020. The main conclusion was made regarding the mechanism of damage to residential buildings: during the period of operation of the facility, in which the uptime to failure has an exponential distribution, the average remaining uptime does not change at any time. It has been confirmed that after a certain period of non-failure operation, the tested MABs perform their functions as new buildings.</p> Asadulla Toshtemirovich Khotamov Copyright (c) 2023 2022-12-31 2022-12-31 183 188 10.47750/pnr.2022.13.S10.16 Improving The Properties Of Mobile Sands With Modified Connectors Based On Local Raw Materials <p>The article examines the possibilities of obtaining a solid-reagent for the production of a polymer-binding additive" SXM-1", obtained on the basis of the waste of the process of production of GIPAN" Navoiyazot "AJ and" Maksam-Ammofos " AJ waste phosphogips, and the possibility of obtaining these reagents as a result of studying the possibilities of obtaining a solid-reagent, the effect of the granulometric and mineralogical composition of the polymer "SXM-1" in the composition of the sand on the hardening of the sand protective layer was determined based on the study of the laws of moisture change and absorption process on the sand surface of various binders</p> <p>On the surface of wet and dry sand, an improvement in the properties of wind and frost resistance was determined based on the formation of a protective layer by means of a polymer solution "SXM-1" and an improvement in the processes of its absorption, moisture retention.</p> Ahmedov Sulton Ilesovich, Professor , Zhuraeva Felura Davronova, PhD Associate Professor Mazhidov Samariddin Rashidovich, PhD, Associate Professor , Saburov Khursand Mambetsalievich, PhD , Khidoyatova Nasiba Shoakbarovna.

The close relationship of pyramidalis with the rectus abdominis muscle has led to the belief that it develops embryologically as a doubling over the rectus abdominis muscle in the ventral portion.</p> <p><strong>Methods:</strong> Thirty-one adult cadavers (26 male and 5 female, embalmed in 10% formalin) and 30 fetuses (14-first trimester, 10-second trimester, and 6-third trimester; embalmed in 10% formalin) were dissected in the present study.</p> <p><strong>Results:</strong> The prevalence of muscle was found to be 87% in adult and 100% in fetus. In 77% of adult cadavers the muscle was present bilaterally and in 10% of adult cadavers the muscle was present unilaterally. In fetuses the muscle was present bilaterally. Few variations related to size and appearance of muscle were observed in both adult and fetus pyramidalis muscle.</p> <p><strong>Conclusions:</strong> The prevalence of pyramidalis muscle was 100% in fetus, whereas in adult it was 87%. The regression of muscle may be the reason behind this difference. In monkeys and prosimians, the pyramidalis tense the abdomen for compression of glands, helping in the expression of milk. Therefore it is speculated the pyramidalis muscle is atavistic owing to the loss of supernumerary nipples in humans.</p> <p>The calculated Pyramidalis-pubo umbilical index was proportionately more in fetus than the adult pyramidalis muscle.</p> Suhani Sumalatha, Sharanya Rao, Vrinda Hari Ankolekar Copyright (c) 2023 2022-12-31 2022-12-31 197 204 10.47750/pnr.2022.13.S10.18 Growth Performance And Organoleptic Evaluation Of Broiler Fed With Medicinal Leaf Meal Supplementation <p>The effects of medicinal leaf meal on the growth performance and organoleptic qualities of broiler meat were conducted at experimental poultry house of Isabela State University, Cauayan City, Isabela from December 26, 2012 to February 6, 2013. A total of 120 three day-old broilers were randomly assigned to four dietary treatments: T1- Home mixed Ration without medicinal leaf meal, T2- Homemixed Ration with 0. 50% Turmeric Leaf Meal, T3- Home mixed Ration with 0. 50% Herbaka Leaf Meal , T4- Home mixed Ration with 0. Insignificant weekly body weight of the birds was recorded indicating that inclusion of leaf meals did not enhance body weight of the broilers.</p> <p>The effect of leaf meal influences the gain in weight of the birds over the birds at fifth week of the feeding trial. The fourth-week percentage rate of growth exhibited significant differences in which the birds fed with holy basil and herbaka leaf meals obtained the highest rate of growth. The results arising from the feed cost analysis show that it is highly beneficial to include any of the medicinal leaf meal, which is highly reasonable. The addition of medicinal leaf meal to broiler diets increases income, as shown on the return above in the feed cost analysis. The incorporation of medicinal leaf meal, particularly herbaka leaf meal, could reduce the production cost of broilers as shown in the return above feed cost, thereby making it recommended</p> Khrissenda May C.

It is caused by the bacteria <em>Streptococcus mutans</em>, a major pathogen which when infected, creates an acidic environment in the mouth leading to the formation of biofilm thereby ends up in tooth decay.&nbsp; Dental caries can be managed by oral hygiene practices, fluoride application, pit and fissure sealants as the primary treatments today with temporary solution. But, Siddha medicine is emerging in treating the Dental caries which remains as the mainstay after all these years for the large population. In this study, Solanum xanthocarpum is identified as the Siddha form of medicine which consists of phytochemicals such as Carpesterol, Oleic acid, Solasodine, Diosgenin, Lupeol, Apigenin, Tomatidenol, Caffeic acid, Scopoletin that interacts with the binding site of target Glucosyltransferase (GFT) – PDB – 3AIC core amino acid residues (Asp588, Gln960, Glu515 and Asp477)of the <em>S. mutans</em>, binds with them and inhibit the synthesis of Extracellular polysaccharides through which the biofilm formation is suspended. The docking studies were carried out using identified phytocomponents against GFT proving the binding efficiency with all 4 amino acid residues by Carpesterol, Oleic acid, Solasodine followed by Diosgenin, Lupeol, Tomatidenol, Caffeic acid, Scopoletin bound with 3 amino acid residues.</p> R.

Neonatal bladder rupture leading to urinary ascites is extremely rare and very few cases have been reported in preterm neonates . The underlying etiology may be spontaneous or iatrogenic. The most common cause of bladder rupture in neonates is the umbilical catheterization, accounting for 75% cases. Obstructive uropathy like posterior urethral valve, abdominal trauma, neurogenic bladder, iatrogenic injuries during surgical procedure, birth trauma, difficult obstetric delivery, and forceful urethral catheterization may also lead to bladder perforation . Very rarely, it can occur due to ischemic injury caused by prolonged hypoxia, which may be precipitated by drugs like morphine administration, birth asphyxia, and poor perfusion.

Their attitudes toward patient safety could affect the patient experience in the hospital setting. Contrasting evidence in the previous study on the relationship between duration of working experience with the attitude toward patient safety warranted further exploration in the current pandemic era. The purpose of this study was to determine the perception of attitude towards patient safety and other associated factors. A cross-sectional study was conducted involving nurses from selected teaching hospitals in Klang Valley, Malaysia during the Covid-19 pandemic period. Data was collected using validated online Safety Attitude Questionnaires (SAQ). The target group was nurses in charge of general medical and surgical wards and was conveniently sampled. A total of 152 nurses participated and had working experience of more than 2 years (93.4%). The majority of positive responses were observed in 4 domains which were the teamwork climate, safety climate, job satisfaction, and stress recognition. The highest positive responses were found for the safety climate domain. In terms of negative responses, it was observed to be highest in the preparation of the unit management domain. However, there was no significant association between any domains with age group, gender, or working experience. In conclusion, the perception of the nurses toward patient safety attitude might be influenced by the managerial style, geographical work setting, and different job scopes. The leaders in a healthcare facility or service delivery should consider focusing on a strategy to ensure adequate management support for the medical personnel that might influence their attitude to patient safety culture in the future.</p> Fatini Nazurah, Nor Azmaniza Azizam, Aniza Ismail, Ahmad Taufik Jamil, Leny Suzana Suddin Copyright (c) 2023 2022-12-26 2022-12-26 258 263 10.47750/pnr.2022.13.S10.026 Credit Risk Analysis Of Islamic Bank VS Conventional Bank In Malaysia <p>The market-based approach is an alternative to accounting-based approach. The use of accounting information alone does not reflect the appropriate level of credit risk for banks. Therefore, comparisons of credit risk between two groups of banks using both approaches are essential. The aim of this present study is two-fold. First, the level of credit risk between Islamic banks and conventional banks was measured and compared. Second, the level of credit risk was empirically compared using several approaches. The credit risk of two domestic full-fledged Islamic banks and four domestic conventional banks was assessed between 2014 and 2018 using two accounting-based approaches (non-performing financing (NPF) &amp; non-performing loan (NPL) ratios) and Z-score. For higher comparability, the level of credit risk was measured based on distance to default (DD) and probability of default (PD) using KMV Merton model as the market-based indicator. Further statistical test for equality of variances was performed to execute a reliable and meaningful comparison between the two bank groups. The results derived from Z-score and KMV Merton model revealed higher credit risk in Islamic banks, in comparison to conventional banks. The NPF and NPL ratios exhibited contradicting outcomes for Islamic banks (lower credit risk). These findings signify that it is vital for Islamic and conventional banks to implement both accounting- and market-based measures as varying approaches yield different results for credit risk assessment. </p> Nurul Farhanah Kamsani, Siti Aida Sheikh Hussin, Zalina Zahid Copyright (c) 2023 2022-12-26 2022-12-26 264 270 10.47750/pnr.2022.13.S10.027 Data Governance Conceptual Model for IoT (DGCMIoT) in Flood Management: the Malaysia Perspective <p>Internet of Things (IoT) is seen as a promising technology that can effectively collect data through varieties of devices and sensors that are placed at every imaginable places.

Virtual reality (VR) is becoming increasingly popular in the realm of physical education, and it is not surprising. Many scholars have been sparked to investigate the use of virtual reality technology in physical education as a result of this information. To see if virtual reality (VR) will have the same effect on body motions as traditional PE methods, this study was carried out to see if VR was accepted in physical education. In order to construct this application, ADDIE instructional design was used. Virtual reality (VR) applications are typically built with an approach that incorporates a combination of motor learning and the technology acceptance model (TAM). A diverse group of participants, ranging in age from 19 to 23, took part in this research. For the VR group, the students were labeled as "VR" and "TR" for the traditional group. Zig-zag run, jumping jack, jumping rope, and obstacle jumps are the four activities that each group has completed. They observed the total mean difference between the VR group and the TR group to determine whether VR technology can give the same effects on bodily movement as traditional methods by recording heartbeats before and after activities. This is because the heart rate rises as the body's various parts are compelled to act quickly. Interviews with five pupils have been scheduled to see how they respond to technology. This study yielded a wide range of findings. This technology is very appealing to a large majority of respondents, who found it easy to use and useful in physical education.</p> M.A.A.M.

However, current work primarily focuses on implementing simulation models in open public spaces with large populations, such as for a whole country. Not all communicable diseases are active in an open space; some illnesses like Tuberculosis (TB) spread actively in a condensed and closed area. Hence, in this paper, we develop a simulation using the Susceptible-Infected (SI) model on TB with the combination of the social force model to portray the heterogeneity of human behaviour. This model is applied to a small community with 30 to 120 population numbers within a closed space. We use the computational model to evaluate the effect of total populations on the reproduction number of TB transmission and the infection time. The reproduction number of TB spread in a closed area is influenced directly by the infection time and the number of total populations. The result indicates that knowing the reproduction number of a communicable disease can predict the spread of illness, and preventative action can be performed to limit the disease. Based on the simulation, we found out that the simulation model generates R_0&gt;1 and the infection time falls between six hours and two years, mimicking the duration of the real-life incubation period for TB. The research may benefit public health in forecasting TB transmission and controlling the outbreak.</p> Nor Shamira Sabri, Fadratul Hafinaz Hassan Copyright (c) 2023 2022-12-26 2022-12-26 308 316 10.47750/pnr.2022.13.S10.032 The Integration of Agent-based Model and Social Force Model: Realistic Pedestrian Simulation <p>The fitted pedestrian modeling is vital to construct realistic pedestrian movement dynamics based on the simulation objective. The inclusions of realistic human characteristics are essential in building a realistic pedestrian model to re-enact the actual movement of the crowd, especially during a panic situation. This study compared the discrete approach CA model with the continuous approach ABM model and the enhanced ABM-SFM model using 30 pedestrians in a sample layout to validate and improve the near realistic pedestrian simulation model. The ABM and ABM-SFM models were integrated with the Pythagorean Theorem (PT) to imitate the driving forces in the desired motion. The results showed that CA localization can imitate pedestrians' sudden, unorganized panic but cannot mimic human intelligence in decision-making and forces avoidance. ABM and ABM-SFM models were on par for the first 10 pedestrians evacuated. However, the ABM-SFM model reduced travel distance by 37.50% and evacuation time by 9.04% after 20 pedestrians were evacuated. Overall, the travel distance for escaped 30 pedestrians with the ABM-SFM model was 39.29% longer, and the evacuation time was 13.96% longer than ABM. The ABM model simulates the pedestrians’ movement towards the nearest exit point to form the “fast escape” approach. In contrast, the ABM-SFM model simulates the “safe escape” to provide balance usage of exit points.</p> <p> </p> Najihah Ibrahim, Fadratul Hafinaz Hassan Copyright (c) 2023 2023-01-30 2023-01-30 317 331 10.47750/pnr.2022.13.S10.033 Ancillary Services from Advanced Metering Infrastructure (ASAMI) in Distributed Renewable Energy Network – A Brief Review <p>The broad view of the smart grid, ancillary services benefits from the smart grid, and enhanced metering infrastructure in numerous developed and developing nations were described in this study.

In this paper, we propose a hybrid model of Analytic Hierarchy Process (AHP) and Evolutionary Game Theory (EGT) to demonstrate the information security scenario, hence, to solve the problem faced. Firstly, the AHP is applied to evaluate the criteria of information security control. The priority of the alternatives is then determined based on the evaluation of the criteria. Secondly, we model the defence-attack situation by the EGT, where the strategies and payoffs for both parties will be formulated. We apply the replicator dynamic to analyze the evolution process of the game, henceforth the optimal strategy is decided.

The existing different types of hospitals had exhibited different characteristics of patient safety attitude perception in the past. However, there was a lack of comparative study on the patient safety attitude for a different type of hospitals. The main purpose of the study was to compare the patient safety attitude perception of the nurses in teaching hospitals with different establishment periods. A cross-sectional study was conducted in 2 selected teaching hospitals with a difference in characteristics. The validated Safety Attitude Questionnaire was utilized for data collection of nurses working in general medical and surgical wards via an online survey form. A total of 152 nurses were recruited as participants with the majority coming from more established teaching hospitals [TH1] (109/152). The gender (p&lt;0.05) and years of working experience (p=0.006) were significantly different between the two hospitals. It was found that 5 out of 6 domains of patient safety attitude revealed significantly different types of responses when compared between these two hospitals. A higher proportion of positive responses was found for the majority of items by the nurses of TH1. A teaching hospital with a longer operational duration and a bigger number of beds could influence the perception of patient safety among the nurses. Thus, policymakers could create a policy that should be able to cultivate a positive patient safety attitude specifically for the newly established hospital. One of the policies is by recommending the teaching hospital managers to practice a workplace pre-placement patient safety training briefing or short courses for the newly appointed nurses in the future.</p> <p> </p> Leny Suzana Suddin Copyright (c) 2023 2023-01-30 2023-01-30 351 356 10.47750/pnr.2022.13.S10.036 An Integral Transform for Solving the Material Balance Equation <p>The concentration of ions in a lithium cell plays an important role in predicting the charge-discharge cycle in a secondary battery. This is done by understanding the transportation processes in a lithium-ion cell during charge/discharge cycle. This paper presents the equations used in the mathematical modeling of a lithium cell. The model equations include the material balance equations, the Ohms Law and the flux equation for the porous electrodes in both the solution (electrolyte) and the solid phases. These equations are then solved analytically, by means of Laplace transform, to give the concentration profile of the lithium ion with respect to the distance and time. The solutions to these equations are plotted in order to understand the profile of lithium ions concentrations during charge/discharge. These plots offer a clear view into how change in one variable interact with other variables and hence could help battery developers predict the performance of their batteries.</p> S. A.

The model classifies the datasets of a construction project into one of the five classes such as tolerable, low, medium, high and intolerable level of risk. As agreed, the probability of risk (RP) and the impact of risk (RI) were selected as the inputs for assessing the level of risk (RL). MCS tools have been widely utilized to deal with the inherent variability in construction systems and is a very useful technique for modeling and analyzing real-world systems. The objective of this paper is to evaluate the use of MCS to quantify project risk. Consequently, risk assessment using MCS to represent risk RP and RI is carried out. Using the Monte Carlo method, the risk on processes (R2), construction error (R4) and process delay (R6), low productivity (R8), quality issues (R12), and technical problem (R13) were evaluated in a LOW-HIGH risk range, while the MEDIUM-HIGH risk was contributed by processes (R1), inexperienced project management team (R3), design errors (R5), construction errors (R7), inexperienced site workers (R9), site accidents (R10). At 95% certainty, the highest risk on the project was contributed by construction error (R7) and delay in delay (R11), with a mean value of 56%, followed by risk on design error, R5 (55.8%), risk on inexperienced workers, R9 (47%), and risk on inexperienced project management team, R3 (46.5%).</p> Fatin Amirah Ahmad Shukri, Zaidi Isa Copyright (c) 2023 2023-01-30 2023-01-30 366 376 10.47750/pnr.2022.13.S10.038 THE PERCEIVED EFFECTIVENESS OF USING MOBILE LEARNING AMONG UNIVERSITY STUDENTS <p>The inability to successfully employ mobile technology for online learning in order to preserve one's learning performance is becoming a big issue. This problem cannot be solved simply by creating more parks and boosting funding for development and administration. There is an urgent need for change, for a better understanding of mobile electronic gadgets' current and future responsibilities in satisfying the needs of modern urban living. As a result, building and controlling the aforementioned technology requires a strategic strategy in order to carry out its functions and tasks. The objective of this research is to investigate how university students assess the efficacy of mobile learning in terms of effort expectation, perceived pleasure, contentment, mobile self-efficacy, behavioural intention, and social aspects. It focuses on UiTM undergraduate students as a unified representation of university students in the context of online learning. This study is based on data obtained from an online survey questionnaire that polled students’ perceived effectiveness of using mobile learning based on the six constructs of the UTAUT model. The data was analysed to determine and assess students' opinions of the efficacy of mobile learning, which may influence students' expected learning outcomes. According to the findings of the study, the perceived success of using mobile learning is related to expected learning outcomes.

Rainfall modelling is vital in water resource planning and management, irrigation, flood prevention, risk evaluation, reservoir management and disaster management. However, improvement on hydrological studies have to be done looking at the surge impacts of climate-related natural disasters in Malaysia in recent years. These damaging disasters may report a scenario where incomplete data has been one of the obstacles for rainfall forecasting. Missing data is very common in time series data as sensor malfunction is unavoidable. There are limitations to perform accurate estimation for missing rainfall data. However, completeness of the data for advanced analysis is crucial. Without precise information in a dataset, the rainfall modelling and forecasting will not be fruitful. A few imputation techniques are proposed for the comparison purposes in the ten rainfall gauges in four different districts in Kelantan with missing values fall into category of Missing Completely at Random (MCAR). According to the performance criteria, Root Mean Squared Error (RMSE) and Mean Absolute Error (MAE), K Nearest Neighbor (KNN) outperformed imputation with mean, median, interpolation, LOCF, moving average, imputation by random sample, replaced by a defined value and seasonally decomposed. KNN exhibits stable performance across the different rainfall gauges in Kelantan with lowest RMSE and MAE. </p> Lee Shee Chia, Chin Wan Yoke, Ho Ming Kang Copyright (c) 2023 2023-01-30 2023-01-30 393 404 10.47750/pnr.2022.13.S10.041 The Impact of Blended Learning Upon Mathematics Attitude and Academic Achievement <p>The Malaysia education system had changed due to enforcement of Movement Control Order by the government. The students are required to learn in their own space using mobile devices as intermediaries. The education system has implemented blended learning and the students learn through that particular instructional strategy. Yet, the concern arises with regard to the blended learning method's impact toward high achieving students. Thus, the purpose of the study is to identify the impact of blended learning toward high achieving students’ attitude toward mathematics, how the students perceive learning mathematics through blended learning and the impact of blended learning toward students' mathematics achievement. The purposive sampling had been implemented in targeting high achieving secondary school students who enrolled in 2 in daily schools in Bachok, Kelantan which indicates school B and C, involving 100 students. The descriptive statistic used in analyzing the finding. Based on the finding, there is a positive impact of blended learning toward high achieving students' attitude in Mathematics. However, the finding shows that the students did not favor learning mathematics through blended learning and they preferred learning through traditional learning. Moreover, from the findings also, it shows that the high achieving students' achievement decreases and the majority of the students get lower grades during blended learning.</p> Joseph Boon Zik Hong, Nur Nazathul Adha Binti Abdullah, Cheong Tau Han, Teoh Sian Hoon, Asmahan Bt Abd Razak, Li Juan, Kee Boon Hui Copyright (c) 2023 2023-01-30 2023-01-30 405 413 10.47750/pnr.2022.13.S10.042 Effect of Deferred Tax Expense, Current Tax Expense, Accrual Basis, and Audit Quality on Earnings Management <p>This study aims to analyse the impact of deferred expense, current tax expense, accrual basis, and audit quality on earnings management.

Users can physically interact with projections to influence the visual display which appears to the audience. Examples include interactive floors and walls. Interactive projection mapping is currently used not only for entertainment but also in the field of education to help students learn. Unfortunately, there is not a lot of research that focuses on planning compared with other research topics, especially in Information Technology. This research has a great impact; however, it makes it difficult for the researchers and even developers to find out the ideal framework for an interactive projection mapping scenario. As the result, the interactive projection mapping solution is still rare to be found in education. Researchers take this opportunity and propose a design plan for creating interactive projection mapping. One design plan can be used for both the wall interactive projection mapping and the table interactive projection mapping installation styles, which makes this design plan unique. It is hoped that researchers will not only be able to design interactive projection mapping for one installation style but can also choose an installation style that is suitable for the environment they wish to use.</p> Maria Seraphina Astriani, Jude Joseph Lamug Martinez, Bayu Prakoso Dirgantoro, Lee Huey Yi Copyright (c) 2023 2023-01-30 2023-01-30 422 430 10.47750/pnr.2022.13.S10.044 Bee AR Teacher Collaborative Learning Augmented Reality Framework <p>Collaborative learning is crucial to be applied in the field of education especially when teaching the students to achieve effective learning. Since the spread of COVID-19, home learning has now been widely implemented and learning methods are generally transformed from conservative ones that required face-to-face meetings to online (using an internet connection as a medium). Teachers have experienced difficulties because the interactions and collaboration that usually can be obtained in offline (face-to-face) sessions do not occur during online sessions. The use of Augmented Reality technology is believed to solve this problem. However, the current framework is quite difficult to be find and also rarely discusses collaborative learning topic. Researchers see a gap and try to bridge it by developing an Augmented Reality framework called Bee AR Teacher for collaborative learning. Bee AR Teacher collaborative learning framework is expected to be able to help developers or researchers to create Augmented Reality solutions that can help teachers create their own applications so it can be used by the students.</p> <p> </p> Maria Seraphina Astriani, Raymond Bahana, Arif Priyono Susilo Ahmad, Lee Huey Yi Copyright (c) 2023 2023-01-30 2023-01-30 431 438 10.47750/pnr.2022.13.S10.045 ANALYSIS OF THE PROBLEMS AND OPPORTUNITIES OF THE BUILT-IN SATELLITE AND TERRESTRIAL IOT NETWORKS IN THE CONDITIONS OF THE REPUBLIC OF UZBEKISTAN <p>Large mountainous and desert areas of the Republic of Uzbekistan were not covered by terrestrial network connections.

To conduct a quantitative assessment of the iodine content, 367 urine samples were collected (schoolchildren aged 11-15 and among pupils in kindergartens aged 4-6). Criteria for assessing the severity of IDS were chosen criteria developed by WHO experts. To determine the concentration of iodine in the urine, the method of Nawschinek O. et al., improved by Mishchenko B.P., was used. and others (10). The obtained data were statistically processed using the MS Excel software package.</p> <p><strong>Results</strong>: A comparative analysis of the prevalence of diffuse goiter showed that the incidence of goiter I degree decreased from 50.8% in 1998 to 20.2% in 2022. The incidence of goiter II degree decreased from 13.7% in 1998 to 2.7% in 2022. The present study showed that in 2022 the prevalence of diffuse goiter in the region was 22.9%, which indicates a dynamic decrease compared to 1998, although the degree of DY remains moderate. An analysis of ioduria showed that the optimal intake of iodine was found in 58.9% of the population, in contrast to 1998 (lack of iodine in the diet in 95.1%).</p> <p><strong>Conclusions</strong>: There is a decrease in the prevalence of endemic goiter in dynamics from 64.5% in 1998 to 22.9% in 2022, which indicates a positive trend.

Nanoindentation was used to assess the hardness and elastic modulus of the intermetallic stages in the matrix alloy. When 20% carbides were added to the alloy matrix, the elastic modulus increased by 35–40%. All materials had a wear rate of 2–8*10−5 mm3/Nm.

Fuel cells are a good remedy for dealing with this energy deficiency. Proton exchange membrane (PEMFC) is the most popular and commonly used one among the different kinds of fuel cells (FC) due to its high efficiency. In this paper a 3D model of a simple nafion based PEMFC is designed and studied for its current density under varying mass fraction of hydrogen. This study helps in determining the optimum mass fraction of inlet fuel such that both overhydration and dehydration of Nafion in the cell can be avoided and it also helps&nbsp; to regulate the cell temperature below the glass transition temperature of the Nafion membrane.</p> Nishanth A, Robin Raju, Vikas Rajan, Gouri Nandana P.R Copyright (c) 2023 2022-12-31 2022-12-31 491 498 10.47750/pnr.2022.13.S10.052 EFFECT OF FRICTION STIR WELDING PARAMETERS ON DIFFERENT JOINTS AA7075-T651 AND AA6351-T6 ALUMINUM ALLOYS <p>This study examined the tensile strength of two variant aluminum alloys, AA6351-T6 and AA7075-T651, by combining them in a butt joint arrangement. It was possible to use friction stir welding to weld shapes like as cylinders and triangles with tool profiles like squares, as well as rates of 40, 70, and 90 mm/min. With a maximum SV/DV ratio of 2.4 for other tool profiles, the square pin profile provided the best pulsating activity. An investigation of the nugget zone microstructure indicated that inadequate stirring of the materials caused some fractures at higher welding speeds. According to a microhardness study, the HAZ of both zones was shown to have a decreased microhardness on both sides. According to the test results, the rigidity of the nugget zone in the center was greater than the BM of AA6351-T6 and less than AA7075-T651. Process parameters were combined according to the Taguchi optimization approach, which resulted in improved tensile strength for the final product. When the process settings were optimized, the following dissimilar joints could achieve a maximum tensile strength of 183MPa: Welding Speed: -70mm/minute, Tool Rotational Speed: 1200 rpm and Tool Profile Square.</p> T.

Using a pin-on-disk dry sliding wear setup, we were able to investigate the effects of 15 and 25 N loads on wear over a range of sliding distances and speeds (600-3600 metres) By increasing the samples’ hardness through MAF cycles, frictional losses and wear mass losses are reduced. Surface layer wear resistance reduces with raising load and sliding velocity. Deformation zones, wear tracks, microcracks and micro-plowing grooves can all be seen on the worn surface. As MAF passes increase due&nbsp;&nbsp; to grain refinement, the current density (Icorr) is clearly demonstrated by potentiodynamic polarisation testing. According to electrochemical impedance measurements, the capacitive arc’s width rise as a result of the reduced corrosion rate. Higher MAF passes demonstrated improved corrosion resistance.</p> Srinivasa Reddy Vempati , M. Pandian , A. Krishnakumari , M. Saravanan , M. Arun , P. Arivalagan , B.

Among these, water scarcity is severe, and the major challenge facing it is to convert a huge amount of seawater to make it available for human use. Many methods exist but are high energy-consuming and are not cost-effective. Energy management is also a major consideration; hence energy consumption can be reduced by using solar energy. Humidification-Dehumidification (HDH) solar desalination system is a widely accepted method due to its cost-effectiveness, and the main advantage is it can be coupled with solar energy, that makes it very energy efficient. The use of coupling with solar makes it affordable in remote areas where transportation and electricity are not there. Optimization of the HDH solar desalination system is important to reduce the size and make it more <a name="_Int_iVdRRBaO"></a>energy-efficient. If the size increases, the pumping power for water to a big area will consume more power. The main objective of this study is to optimize the size of the dehumidifier. The mass transfer coefficient used in this study is based on surface renewal time to study the mass transfer taking place in a dehumidifier. In this study, for the optimized height of the dehumidifier, its width is also optimized to avoid energy losses. Variation of superficial gas velocity and mass flow rate of air is also studied at an optimized width of 0.4m, and the variations are plotted and are being studied.</p> Arun Reji, J S Jayakumar, P Raj Ranjitha Copyright (c) 2023 2022-12-31 2022-12-31 518 528 10.47750/pnr.2022.13.S10.055 FRACTURE BEHAVIOUR OF A COMPOSITE LAMINA UNDER MECHANICAL, THERMAL AND THERMO-MECHANICAL LOADING CONDITIONS <p>Analysis of Composite materials is a challenging task as these materials are influenced by many parameters such as geometry, stacking sequence, type of loading etc. In this work, the fracture response of a composite rectangular plate has been studied under mechanical, thermal and combined thermo- mechanical loading using the Finite element method.

Manipulating slip length to control nanochannel fluid flow is seen as a viable choice. Using molecular dynamics (MD), the study of the nanochannel is done. The effects like the surface roughness, and channel width are all considered to study the slip length and its influence at fluid – solid interface. In this research, the variation brought about in the interaction potential is used for the slip length manipulation and also and the wall is made elastic by altering the spring constant. The variation in slip length in each scenario is achieved. The slip length increases when the interaction potential is less and vice versa. Similarly, when the wall becomes elastic, the slip length reduces.

When choosing a thermoplastic polymer to use in an FDM 3D printing process, the properties like part strength, surface quality, accuracy and mechanical properties can be varied to suit a particular application. The thermoplastic filament materials, viz., Polylactic acid (PLA) and Polyethylene terephthalate glycol (PETG) are the best biodegradable filament materials and exhibit good visual quality and mechanical properties of parts produced by 3D printing. This work investigates the surface roughness quality and dimensional accuracy of 100% infill density parts fabricated by FDM process using Carbon fibre PLA and PETG. The cuboid shaped test specimens with dimensions 40 mm× 40 mm×15 mm are considered. The layer thickness, printing speed, nozzle diameter and nozzle temperature for the printing process are set at 0.1 mm, 30 mm/s, 0.4 mm and 220˚C respectively. To check the dimensional accuracy, in particular the warping deformation, a dial vernier caliper is used. The surface roughness of different surfaces is measured by a portable surface roughness tester. According to the experimental results, both carbon fibre PLA and PETG show good dimensional accuracy in 90˚ measuring direction perpendicular to building direction and best surface quality over 10 mm scanned profile. Specifically, the printed parts of both the materials have got low warping and shape distortions due to heat shrinkage. Also on an average scale, carbon fibre PLA filament material comparatively shows a better surface behaviour than PETG. This study can be extended to other advanced and best performing polymers like PEEK, PEEK CF and PEI/ULTEM, which have good mechanical and thermal properties.</p> Durga Prasada Rao.V , Durga Hemanth Kumar.K , SatishRaja.M , V.Ch.R.K.Santosh.P Copyright (c) 2023 2022-12-31 2022-12-31 553 562 10.47750/pnr.2022.13.S10.059 OPTIMIZATION OF PROCESS PARAMETERS FOR WEDM ON GRAPHENE – BN- AZ91 COMPOSITE THROUGH HYBRID TECHNIQUES <p>Material removal rate (MRR) and surface roughness (Ra) of the recently advanced AZ91 MMC were examined in this analysis using the WEDM (Wire Electric Discharge Machining) variable.

The present work emphasizes on how the impact strength of carbon fibre PLA is influenced by the Fusion Deposition Modeling (FDM) parameters, viz., layer thickness, infill pattern and print temperature. ASTM-D256 type 1 standard is used to design the impact test specimens. Three levels for each of these FDM parameters are considered for the printing process, and to prepare the impact test specimens by FDM, a full factorial design of experiments (33) is selected. The results are analyzed by conducting ANOVA and it is identified that the impact strength of carbon fibre PLA is influenced mostly by the layer thickness. The ANOVA results reveal that the impact strength of carbon fibre PLA is notably influenced by the interaction between infill pattern and print temperature. Also, a moderate influence is observed for the interaction between layer thickness and print temperature on the impact strength. But the interaction between layer thickness and infill pattern has negligible influence on the impact strength. It is noticed from the general linear model obtained out of ANOVA that the impact strength is mainly influenced by the layer thickness followed by print temperature and infill pattern. The Pareto chart and normalized plot drawn for impact strength also reveal that layer thickness, print temperature, in fill pattern, and interaction of infill pattern and print temperature are potentially important and their relative influence on impact strength is in descending order</p> Durga Prasada Rao V , Tarun Kumar Kotteda , Sandeep Varma Kuchampudi , Durga Prasad Balam Copyright (c) 2023 2022-12-31 2022-12-31 600 610 10.47750/pnr.2022.13.S10.063 REVIEW OF RECENT TECHNIQUES IN POROUS MEDIA COMBUSTION <p>Increased use of fossil fuels for the need of power production has led to the extensive development of porous media, which leads to its growing interest in petrochemical and power generation studies. Due to the lean flammability limit, better emission characteristics, higher energy density and strong radiation emission PMC is gaining more attention among researchers. Efforts were undertaken to solve the fundamental concerns associated with porous media for combustion. Thermal coupling between the flame and the combustor geometry plays a decisive role in determining the combustion process, such as flammability limitations, flame stability regimes, temperature, speed of the flame etc. In this review paper, a better understanding and evolution of porous combustors is studied, focusing more on the materials, fuels and recent applications in the &nbsp;PMC technique.</p> Sreejitha Raj, J S Jayakumar Copyright (c) 2023 2022-12-31 2022-12-31 611 619 10.47750/pnr.2022.13.S10.064 FIRE MODELLING AND SIMULATION OF BUILDING EVACUATION <p class="Abstract" style="line-height: 115%; tab-stops: .25in; margin: 0in 0in 8.0pt 0in;">Increasingly more academic institutions are built in towns, but on the identical time fireplace safety requirements of those homes are very critical too. On this present work, distinct fire features for classroom model of school building in fireplace accident has been studied. Single school building fire may additionally motive a large range of fatalities because of the feasible excessive variety of human beings involved in it. In this study, the (CFD) computational fluid dynamics - FDS software method is used to predict the fire dynamics in a classroom of a school building. The dimension of classroom model used in this study measures 10m in length, 7m in breadth and 4m in ceiling height, which is same as the dimension of the selected classroom of the school. Essential aspects of fire features were investigated which include temperature distribution, heat release rate and smoke propagation. The simulation suggests that heat release rate could be very excessive, and also temperature rises to a very high value ensuing in an uncontrollable fire circumstance. The smoke produced through the burning of wood substances of tables, chairs, green boards and display boards leads to poor or no visibility, further making hard for occupants to escape. Effects obtained are important for production or improving fire safety necessities in classroom of school buildings. The result can also be beneficial for fireplace danger assessment and layout of evacuation system in educational institutions.</p> Annapurna Bharti , Rajasekaran G Copyright (c) 2023 2022-12-31 2022-12-31 620 626 10.47750/pnr.2022.13.S10.065 FATIGUE ANALYSIS OF FIBRE REINFORCED POLYMER COMPOSITE FILLED WITH NANO FILLERS <p>In recent years, polymer composites made with glass fibre and epoxy resin are attracting various industries like automobile, marine, space and airline industries. Carbon nanoparticles have amazing potential to increase the strength of reinforcements and matrices in FRP composites. In this study, three different fibre reinforced composite laminates were made with and without adding the nanoparticles using a hand layup method. Multiwall carbon nanotubes (MWCNT) are employed as a filler material in the laminates which are made using glass fibre reinforced with epoxy resin.</p> <p>Three types of glass fibre-reinforced epoxy laminates such as parent laminate, 0.5% MWCNT added laminate and 1% MWCNT added laminate are subjected to quasi static indentation, Tensile loading and fatigue loading. It was discovered that adding MWCNTs to GFRP changed the mechanical characteristics of the material. The addition of 0.5% carbon nanotubes showed noticeable changes in the mechanical behaviour with 18.86 % increase in tensile strength, 21.59% increase in impact strength and 18.63 % increase in fatigue cycle. Also, addition of 01% carbon nanotubes showed that 28.26% increase in tensile strength, 32.15 % increase in impact strength and35.06 % increase in fatigue cycle.</p> C. Ramesh , D.

To reduce the experimental costs for testing, mathematical models can be implemented to predict fracture behavior. In the present study, a rectangular plate with a delamination defect and a virtual crack was modeled in ANSYS and the fracture behaviour was studied when the mechanical, thermal and thermo-mechanical loads are applied to the plate. The fracture behaviour of the rectangular plate was quantified by the strain energy release rate (SERR) and the effect of the fibre orientation angle, lamina stacking and thickness of the laminate was studied. The SERR increased with the increase in the applied loads. The thermo-mechanical loads have higher impact on the SERR compared to other loads. The increase in the thickness of the laminate reduced the SERR. The Angle – ply stacking sequence has a higher SERR than the cross-ply sequence.</p> V.V.Venu Madhav , Y.

Recent studies have revealed the potential value of these molecules in a variety of biological conditions. Resistance and severe side effects, however, drive research into new and more effective anti-inflammatory and anti-tuberculosis medications. In this research molecular docking analysis along with ADMET and drug likeness prediction were carried out to evaluate the newly designed indazole scaffold as potent Enoyl-ACP (CoA) reductase enzyme and cox-2 inhibitor. Comparing with reference compound docking scores isoniazid (-5.21 kcal/mol) and indomethacin (-6.42 kcal/mol) compound BPM showed highest binding affinities (-7.66 and -7.46 kcal/mol) with respective enzymes. Depending on the specific ADMET risk factors and drug similarity for oral bioavailability, all indazole scaffolds shows significant activity. Present study demonstrated that newly designed indazole scaffold and natural alkaloids containing indazole nucleus could be the potential drug of choice against inflammation and tuberculosis.</p> R.
