Published: October 2022

Student Data Management System is an android application to store and manage student information in modern educational institutions[2]. Traditionally, it has been managed using pen and paper which is not very efficient. Hence the goal of the project is to create an android application for Student Management for storing and retrieving the data of students and faculty for efficient functioning of the academic institutions. The application is to be created with kotlin which is announced as the most favorable language for android developers by Google[5][6]. The data for the application is to be stored in the Android Room Database. User Interface is to be provided using v7recyclerview module, which provides efficient and user friendly layouts. A Smart Assistant allows students to ask queries and get answers from the application by text and voice is to be created using Alan App in kotlin. The users could manage attendance[1], marks and proceed in the track and required data will be stored and managed for future references too.

The process of teaching and learning is the most powerful tool that teachers and professors have, because it is the main way that students change in the ways that teachers and professors want them to. TQM is recommended as a way to control, monitor, and improve the quality of teaching and learning strategies in the classroom. In line with the principles of TQM, evaluations of things like results and feedback are used to improve teaching and learning. The level of academic success that a program's students have may say a lot about how good that programme is. You can predict how well a student will do in school in the future by looking at how well they did in the past. After more research, it might be possible to find a link between the students' grades and their skills and interests. When teachers have this kind of information, they are better able to focus on the students who are having the most trouble. This article shows how to use feature selection and machine learning to improve the quality of teaching and learning in higher education by predicting how well a student will do in school. The performance of university students is used as an input to a classification model. First, ant colony optimization is used to choose the most important features. Then, KNN, Naive Bayes, and decision tree algorithms are used to classify the chosen data. Based on accuracy, recall, and F1 score, KNN performs better.

Authors: Singh Alok , Saurabh Sharma  , Rajneesh Kumar Srivastava
Published: October 2022

AODV is a reactive routing protocol that sets up routes between source and destination nodes as and whenneeded. The performance of AODV protocol depends on the choice of certain parameters including route requestretries which is, by default, set as two in the corresponding RFC. In the present work, the effect of Route RequestRetries (RRR) on a set of performance metrics viz. Normalized Routing Load (NRL), Average End-to-End Delay(AEED), Packet Delivery Ratio (PDR) and Throughput has been investigated for a linear ad hoc network of fivenodes. Three different scenarios have been investigated wherein middle node is made to remain stationary, mobilewith low mobility and mobile with high mobility. Mobility of the middle node is found to be having significanteffect on the performance of such linear ad hoc networks. RRR has no influence on the performance of linear adhoc network of stationary nodes. However, RRR is having significant effect on the performance of linear ad hocnetwork if a node is made mobile. Performance of such linear ad hoc network is also affected by the choice ofduration of simulation.

Published: October 2022

The COVID-19 pandemic is causing a worldwide emergency in healthcare. This virus mainly spreads through droplets which emerge from a person infected with coronavirus and poses a risk to others. The risk of transmission is highest in public places. Many measures have been suggested, such as maintaining a social distance, and wearing a face mask to avoid the spread of this virus. There are three modules in this work, in the first module a mask detection system which detects whether a person wears a mask or not using deep learning techniques such as MobileNet V2 architecture along with Facenet and Masknet. Accuracy of 98.6% is achieved in this module with one or two people in the frame. Barricade has been set which does not allow people who does not wear mask and allows people who wears a mask. LED light indicators and LCD displays are used as alerts, and they are programmed to provide information that is both worn and not worn, depending on the output. In the second module, a system has been designed which detects the temperature of the person and detects whose temperature is above normal body temperature and alerts accordingly. In the third module a social distancing system has been designed which detects people who does not follow social distancing protocol and alerts them using deep learning techniques. The YOLOv3 algorithm is used which creates a square box around people that displays green or red color box according to the measurement output. The transfer learning methodology is also implemented to increase the accuracy of this module. The accuracy of 98.2% is achieved for social distance detection module using YOLOv3 detection model with transfer learning. All three modules are integrated so it automatically monitors human body temperature, detects mask and social distancing at the barricade system.
Pragmatic analysis of ECG classification models & architectures from a statistical perspective
Authors: Komal Jaisinghani  , Dr. Sandeep Malik
Published: October 2022

Electrocardiograms, also known as ECGs, are capable of representing a wide range of heart conditions, such as atrial fibrillation, arrhythmia, myopathy, and heart failure. Operations such as denoising, signal enhancement, feature extraction, feature selection, stratification, and post processing are developed in order to process ECG signals. Depending on the application that is being deployed, these processes may only work in their individual components or in combination with one another. Researchers over the years have developed a wide variety of algorithms, each specifically tailored to accomplish one of these tasks. The computational complexity of these algorithms, the number of diseases they can classify, the degree of accuracy they provide, the cost of deployment, and other factors can vary. For example, models that are based on convolutional neural networks (CNNs) have a high level of accuracy; however, these models are typically slow and highly complex to deploy, and as a result, theyare not used in clinical applications that have a low cost. However, linear classification models such as support vector machines (SVMs) have acceptable accuracy, a moderate level of complexity, but are lacking in terms of precision; as a result, they are not suitable for use in applications that require real-time processing. Because there is such a wide range of algorithms that are available, it is unclear to researchers which models would be the best fit for their application, which leads to an increase in both the cost of deployment and the amount of time needed to bring the product to market. The text that lies beneath this one examines several of the recently proposed ECG classification models and assesses them based on a number of statistical parameters, including computational delay, complexity of deployment, classification accuracy, precision, number of heart diseases covered, and so on.This is done in an effort to clarify the situation and remove some of the ambiguity. After completing this analysis, the text then compares their performance and provides an estimate of the models that are the most appropriate. Researchers now have the ability to select and implement the algorithmic models that are best suited for their deployments based on this review. In addition to that, this reviwe suggests a number of different enhancements that can be made to the models that have been examined, and researchers can implement these suggestions in order to increase the effectiveness of the models.
Modified Neural Network-based Object Classification in Video Surveillance System
Authors: Bhardwaj Rakhi Joshi , Rao D.S.
Published: October 2022

Visual surveillance emerged as an active automated research area of Computer Vision from the traditional mathematical approach to neural networks. A novel modified neural network technique for object detection and classification for input images and video feed from many cameras overlapping target areas is presented in this research.Modified Neural Network methodology represents layered architecture as the input, preprocessing and Operation layer, to simplify the processing needed to prepare for training neural networks. This strategy aids in delegating the tasks to layers with predefined tasks thus simplifying training, reducing computational requirements, and delivering performance. Two modules of the Neural Network will process the input. The first module is a modified Neural Network and will differ from traditional Neural Network in respect of connectivity between Neurons and their operations. This will still be Neural Network for data shared and threshold followed for marking differences – Markers, between the two inputs and simplified training. The second Module will be a traditional Neural Network for detection and classification that will track the detected objects. This paper proposed a system that provides the combined image as an output from multiple cameras feed using an untraditional Mathematical and Algorithmic Approach.

El resultado demostró que al emplear una combinación de ácido cítrico con ácido ascórbico (0.1%) se obtuvo características de preservación de color, olor, sabor y aceptabilidad aceptadas. A manera de conclusión se observa que la aplicación de métodos mixtos de conservación de frutas ayuda a que se generen procesos de valor agregados en frutas como el orito, lo que puede resultar en una alternativa para productores y consumidores.
Experience of music therapy during the weaning process of patients receiving invasive mechanical ventilation
Authors: Morris Stephanie
Published: October 2022

Mechanical ventilation (MV) is a medical intervention used to assist the respiratory function of someone who is medically compromised. Patients need to wean from the ventilator in order to resume breathing on their own. A spontaneous breathing trial (SBT) determines one’s readiness to be liberated from the ventilator. Board-certified music therapists facilitate music interventions to address patient-specific goals within a therapeutic relationship. Music therapists working in an intensive care unit (ICU) may address the stressors, fears, and medical complications associated with vent weaning. The goal of the present study was to determine if one 30-minute music therapy session during an SBT would decrease the patient’s perceived level of anxiety and improve physiologic metrics related to the SBT, specifically, respiratory rate (RR), blood pressure, oxygen saturation, and heart rate (HR). The researcher also sought to understand the perspective of the patient. The research question was: What does the patient experience related to music therapy during their SBT? Data collected from 20 patients revealed that measurements of HR and blood pressure significantly increased pre- to post-music therapy session. Data analyzed in the interviews suggested that music therapy may assist patients in coping with the physical, emotional, and spiritual stressors of weaning from MV.

Published: October 2022

Three stocks of bottlenose dolphins (Tursiops truncatus) are currently known to co‐occur in the coastal waters off Virginia. A combination of visual line‐transect survey and photo‐identification (photo‐ID) methods was used to gather information on the occurrence, distribution and density of bottlenose dolphins in the coastal areas of Norfolk and Virginia Beach. Sixty‐one line‐transect surveys were completed in two zones (inshore and offshore) between August 2012 and August 2015, with on‐effort coverage of 6,550 kilometres (km) of trackline over 349.6 hours. Conventional line‐transect analysis of bottlenose dolphin sightings showed both spatial and temporal variation in density (D) and abundance (N), with highest density in the inshore zone during warm‐water months (June–November). Inshore densities were calculated as 3.51 individuals per square kilometre (km2) (N = 1,090) in the warm‐water season and 0.73 individuals/km2 (N = 225) in cool‐water months (December–May). Densities in the offshore zone were 1.24 individuals/km2 (N = 741) in the warm‐water season and 0.61 individuals/km2 (N = 366) in the cool‐water season. Warm‐water density peaks support previous research; however, this study documents a cold‐season presence of dolphins in both zones not previously reported. Twenty‐seven photo‐ID surveys were completed and a photo‐ID catalogue was created using photos taken during both dedicated photo‐ID and line‐transect surveys, containing 1,335 unique individuals. Re‐sighting numbers were low, with less than 17% of individuals documented on more than one occasion, and only 4% sighted on three or more occasions, with a maximum of 4 re‐sightings. Days between re‐sightings ranged from 5 to 970, though distance between re‐sightings spanning greater time was minimal (less than 25km). Sighting locations of photo‐IDed dolphins were broken into three regions to investigate seasonal and spatial patterns of individual distribution; dolphins sighted only in the Cape Henry (CH) or Inner Bay (IB) region were observed mostly during summer and fall seasons (93% CH, 100% IB) with none occurring during winter. For the Outer Coastline (OC) region, the majority of sightings (88%) occurred during fall and winter. Additionally, there were two individuals sighted during winter months also sighted during summer more than 130km to the north inside Chesapeake Bay (matched to a different catalogue). These sightings support the possibility that the current stock structure does not account for all dolphins in the region. Stock structure as currently understood is complicated, with overlapping spatial distribution of three stocks that separate seasonally. Our study provides information that may be useful for management, but also additional findings that could impact future stock designations

This study uses secondary data, namely: Export Value through the Port of Kumai, Sampit, Pulang Pisau, and Pangkalan Bun, and Economic Growth in Central Kalimantan Province during 2007-2021. The results of the Multiple Linear Regression analysis of the Semi Logarithma Model partially show that the Export Value through the Port of Loading at the Ports of Kumai and Sampit has a significant and positive influence on Economic Growth in Central Kalimantan Province. In contrast, the Export Value through the Port of Loading Pulang Pisau and Pangkalan Bun has no effect but is positive on Economic Growth in Central Kalimantan Province. However, simultaneously the export value through the loading ports at the ports of Kumai, Sampit, Pulang Pisau, and Pangkalan Bun has a significant influence on economic growth in the province of Central Kalimantan.
Learner-Centred Approach: Its influence on Quality of Learning in Public Secondary Schools in Hanang District
Authors: Qambaday Daudi , Mwila Prospery M.
Published: October 2022

Learner Centred Pedagogical Approaches have become a global practice in the teaching and learning process. The approaches have been credited with the potential to impart learners with different skills and prepare them to work effectively in this ever-changing world. This study investigated the role of learner centred pedagogical approaches on quality learning in public secondary schools in Hanang District. The Social Constructivism Theory by Vygotsky (1968) provided a theoretical lens to this study. The Mixed research approach and a Concurrent embedded research design were used in this study. Data was obtained from a sample of 174 participants, including students, teachers, Heads of schools, Ward Education officers, and District Education officer. Questionnaires and interview guide were used to collect primary data. Quantitative data were analysed through descriptive statistic with the help of Statistical Package for Social Science (SPSS) version 21 while Qualitative data were analysed thematically. The study revealed that learner centred approach contributes to quality learning through student’s involvement in complex learning situations in the classroom and ensuring active learning in the classroom. The study also reported that learner centred approach attracts learner’s interest and thus enhances good academic achievement. On the basis of the findings, it was concluded that though learner centred approach had contributed in some way to improving quality of learning it had failed to influence –effectively, the quality of learning because of some challenges. Among challenges identified includes; lack of enough knowledge on implementation of learner centred, teacher’s resistance to change, overcrowded classroom, teacher’s low morale, poor teaching and learning material. Therefore, the study recommended that school administrators should work tirelessly resolve these challenges- for better implementation of learner centred approach in secondary schools in the country.

Published: October 2022

A Educação formal tem seu início desde o século XIX, atravessou o século XX com diversas transformações educacionais por grandes teóricos da pedagogia, que até hoje, em pleno século XXI, são estudados. A preocupação com a autonomia do aluno desde a primeira infância, o amadurecimento emocional na educação infantil - como ressalta Montessori; entre brincadeiras de forma lúdica, com o aprendizado e a metodologia construcionista, de Papert, discípulo de Piaget, para que os alunos possam apropriar-se de saberes cognitivos, que, com projetos didáticos-pedagógicos enriquecem a educação. Logo, em contato com a natureza, como nos ensina Freinet e respeitando a idade cronológica de cada estudante como Waldorf defende, e Vygotsky nos assegura que a zona de desenvolvimento proximal, seja real no processo de ensino-aprendizado, onde a postura ética do professor-mediador, a inclusão das pessoas com deficiências e a acessibilidade nas escolas. Na atual contemporaneidade do século XXI, a renovação da educação escolar, agora pela informatização. Faz-se necessário a educação continuada na aprendizagem tecnológica para o professor não ficar desatualizado em relação aos alunos, complementando os Projetos Políticos Pedagógicos das escolas, que com a era digital, a conexão escola-família acontece via WhatsApp. Esse trabalho demonstra a verdadeira herança que o professor tem de seus antecessores, pois, além das teorias, é o dever de sempre prosseguir no caminho do processo de ensino-aprendizagem: sua renovação, evolução e continuidade.

Authors: Cuc Nguyen Thi Thu , Van Nguyen Khoa Dieu , Thuy Nguyen Tran
Published: October 2022

The risk of cardiovascular injury and death in type 2 diabetes patients is 2 to 4 times higher than in the general population. Patients with type 2 diabetes at high cardiovascular risk were defined as having 10 years of diabetes without end-organ damage and/or any additional risk factors such as hypertension, dyslipidemia, smoking, or obesity.

Aims: To investigate blood-glucose control status and some related factors in patients with type 2 diabetes with high cardiovascular risk.

Methods: A cross-sectional, prospective study of 85 diabetes patients with high cardiovascular risk who visited the Outpatient Department, Bach Mai Hospital from November 2021 to August 2022.

Results: The average age is 55.9 years old, with 60.0% of the population being female. When follow-up began, the ratio of HbA1C < 7 was 51.8%; and the mean HbA1c was 7.79 ± 2.1% and the mean fasting plasma glucose was 8.78 ± 3.05 mmol/L. After the follow-up period, HbA1C < 7 was 50.8%, mean HbA1c was 7.21 ± 1.13%, and the rate of noncompliance with treatment was 20%.

High cardiovascular risk factors in patients with type 2 diabetes include: dyslipidemia (91.8%) and hypertension (44.7%), smoking (16.5%), obesity (24.7%), and family history of early cardiovascular disease (3.5%). 80% of patients had 1-2 concomitant cardiovascular risk factors.

Conclusion: Blood glucose control is associated to exercise regimen, medication compliance, number of hypoglycemic drug classes, and years of diabetes. The majority of patients with type 2 diabetes who are at high cardiovascular risk do not achieve multi-risk factor control goals, which is mainly correlated to medication compliance.

Authors: Hoan Nguyen Dinh , Thuy Nguyen Tran
Published: October 2022

Background: The presence of good coronary collateral circulation (CCC) can protect and preserve myocardium from ischemia, increase myocardial contractility, and reduce adverse clinical events. However, its impact on mortality is still a topic of debate, particularly in acute coronary syndrome (ACS). The aim of this study was to investigate the association of CCC with cardiac risk factors and in-hospital mortality in patients hospitalized with a diagnosis of ACS.

Methods: The study population included 200 patients with ST – elevation myocardial infrarction who underwent coronary angiography and were found to have TIMI flow coronary 0 or 1. The CCC was graded according to the Rentrop classification. The patients were classified into a poor CCC group (Rentrop grades 0-1, n=161) or a good CCC group (Rentrop grades 2-3, n=39). Following of major adverse cardiac events about 30day after PCI.

RESULTS: Patients with good CCC had time onset chest pains (p = 0,001), higher rate of Killip class of at least 2 at admission (p = 0,031), peak troponin T (p = 0,037), lacticemia lower (p = 0,03), multivessel lesion upper (p = 0,03) with the patients with poor CCC. MACE of patients with good CCC nosignificant with the patient with poor CCC (OR=3,9, 95%CI[0,5- to 30,5], mortality (HR 2,5, 95%CI[0,31-19,2], p=0,45), unplanned target vessel revascularisation (TVR) (HR 28,8 (0.006 to 1.4), p=0.44), comelack  in-hospital by cardiovascular causes (HR 1,06, 95%CI[0,29 to 3,7]. P=0,93). Increase left ventricular ejection fraction after 30day in patients with good CCC upper patients with poor CCC (p=0,004).

CONCLUSION: In contrast to previous studies, our study did not confirm a beneficial role of good CCC in patients with ST – elevation myocardial infarction.

Hypertrophic obstructive cardiomyopathy is a rare cardiac disease occurring in approximately 0.2% of the population and is usually left ventricular hypertrophy associated with or without mitral regurgitation due to SAM syndrome. Medical treatment, first septal ablation with absolute alcohol, or left ventricular myectomy are the treatment methods for this disease. We report the surgical results of a case of obstructive bilateral ventricular hypertrophy associated with a myocardial bridging of the left anterior descending artery.

The article discusses the sect of Mutazilism, which is defined as supporters of freedom of thought and considers reason to be primary in the science of aqeedah, and its main ideas. In particular, the views of the Mu’tazilites on state management and the fact that these views have been taken as a basis by today’s misguided sects have been thoroughly analyzed. At the same time, the views of the Mu’tazilites on the issue of fate, sustenance, good and bad deeds of man, the creation of heaven and hell, the torment of the grave, and the reckoning of the servants in the Hereafter are described.
In addition, the views of the Ash’arites and the Maturidis on these issues are presented for comparison. In this situation, the refutations given to each idea of the Mu’tazilites by the scholars of the Ahl al-Sunnah wal Jamaah based on the Quran and Hadiths are mentioned. In particular, a bright representative of the doctrine of Maturidiyya, Abu al-Mu’in Nasafi’s refutations against the ideas of the Mu’tazilites are studied.

Summary: Bile acid malabsorption (BAM) is caused by dysregulation of enterohepatic circulation of bile acids and their synthesis in the liver. Estimated prevalence is about 1% of adult population. BAM has been substantially underdiagnosed. This condition can be present in one third of patients with diarrhoea-predominant irritable bowel syndrome and in 50–100% of Crohn‘s disease with ileitis or previously resected terminal ileum. Up to one half of oncology patients with pelvic radiotherapy suffer from BAM. SeHCAT test (75Selenium HomoCholic Acid Taurine test) is the gold diagnostic standard and the test has just become available in the Czech Republic. Low-fat diet is the most important dietary modification. Bile acids sequestrants (cholestyramine in the Czech Republic) are the crucial part of pharmacotherapy. Key words: bile acid malabsorption – SeHCAT test – cholestyramine

Summary: Introduction: The group of neuroendocrine tumors derived from pancreatic cells is called pancreatic neuroendocrine tumors (PNETs). The combination of EUS and elastography (EG) expands diagnostic and imaging capabilities. Aim: The aim of our work was to determine the representative images of B-mode for PNET, evaluation of a typical EG image of PNETs, use of strain ratio (SR) and “strain histogram” (SH) in differential diagnosis of PNETs, determination of SR and SH cut off value for PNETs and comparison of standardized measurements with literature. Methods: Patients examined at the Internal Gastroenterology Clinic were included in the cohort. A total of 31 patients were examined. The group included 25 patients (8 men, 17 women). The mean age in group was 52.76 years (14–74). Non-invasive examination by endoscopic ultrasonography was performed on all patients. After locating the lesion by ultrasound, the first recording was made after freezing the image in B-mode and performing size measurement. Subsequently, a Strain elastography measurement was performed. In the monitored group we recorded an average size of 12.75 mm. Results: The characteristics of the image in B-mode were as follows for PNETs 68% hypoechogenic, 12% hyperechogenic, 12% isoechogenic and 8% mixed echogenicity. 80% of PNETs in B-mode were sharply demarcated and 20% with blurred borders. The accuracy of the value assignment typical of pancreatic malignancies using elastography was 96% for PNET in 5-degree classification system and 88% for a 4-degree classification, for SR cut off >3.2 with a sensitivity of 80% and SH cut off <50 100%. Discussion: Given the average tumor sizes observed in our study, EUS provides high sensitivity in PNET diagnostics and allows diagnostics at a time when minimally invasive removal is still possible. In addition to the typical picture of hypoechogenicity and the less frequently described pictures of hyperechogenicity and isoechogenicity for PNET, we also observed mixed echogenicity. The elastographic qualitative strain image evaluated by the four- and five- -degree classification proved to be reliable in distinguishing PNET from benign tumors. In quantitative elastography, the values of SR are between malignant and benign deposits of the pancreas, one of the reasons for such values may be the diversity of this group of diseases with different mitotic activity – grade of the tumor. Conclusion: Consistency of the results published by us, shows the applicability of this method in deciding on a definitive diagnosis if tumor histology is not and cannot be available. Key words: neuroendocrine tumor – pancreas – ultrasonography – elastography

Summary: Introduction: Insulin resistance (IR) is a hallmark of non-alcoholic fatty liver disease (NAFLD), which has been associated with worse long-term survival and more frequent occurrence of chronic kidney disease (CKD) than in patients without NAFLD. The aim of our study was to evaluate the impact of NAFLD and IR on survival and renal function in patients after liver transplantation (LT). Methods: Our prospective study included 96 LT candidates who were observed after LT. We evaluated patient survival and occurrence of CKD (defined as estimated glomerular filtration [eGFR] ≤1.00 mL/s/1.73 m2 or overt proteinuria) 5 years after LT and at the end of follow-up. Clinical, laboratory, MR and elastographic evaluation before and 1 year after LT were performed as well as liver biopsy 1 year after LT. Results: Of the factors present 1 year after LT, higher ALT (P = 0.021), ALP (P = 0.012) and everolimus treatment (P = 0.025) increased the risk of death at the end of follow-up, borderline significance was found also for higher waist circumference (P = 0.058), AST (P = 0.059), HOMA-IR (P = 0.056) and presence of fibrosis stage ≥3 in biopsy (P = 0.055). In addition to the presence of CKD 1 year after LT (P <0.001), other independent posttransplant risk factors of CKD 5 years after LT included presence of IR defined as HOMA-IR ≥3 (OR 4.33; 95% CI 1.25–15.04; P = 0.021) and higher serum high-molecular-weight (HMW) adiponectin (OR 1.25; 95% CI 1.03–1.50; P = 0.021). Of the factors present 1 year after LT, diabetes treated by antidiabetics (P = 0.008), higher serum levels od triglycerides (P = 0.031), C-peptide (P = 0.022) and leptin (P = 0.002) and lower total bilirubin (P = 0.006) were associated with lower eGFR at the end of follow-up. We observed a trend towards higher eGFR levels in patients treated with everolimus (P = 0.055). We did not observe an impact of grade of steatosis and presence of steatohepatitis on biopsy 1 year after LT on survival or renal functions. Conclusion: Presence of IR 1 year after LT independently increased the risk of CKD 5 year after LT. Patients with higher HOMA-IR 1 year after LT had a trend towards worse survival at the end of follow-up. Key words: insulin resistance – non-alcoholic fatty liver disease – liver transplantation – chronic kidney disease – survival

Summary: “Black esophagus”, also known as acute esophageal necrosis (AEN), is a relatively rare disease characterized by black discoloration of the esophageal mucosa. The condition can be located only distally, but it can also affect the entire esophagus. Hematemesis is the most common clinical manifestation is; the condition is associated with increased lethality in high-risk groups of patients. Early diagnosis of AEN can be made by gastroscopy, the initiation of adequate treatment is crucial for a favorable patient prognosis. The most serious complications of AEN include esophageal perforation with the risk of other complications such as mediastinitis and sepsis. The nature of the disease and the affection of the esophagus and potentially the mediastinum require a multidisciplinary approach. Below we present a case report of a 68-year-old patient with a diagnosis of AEN complicated by perforation confirmed by CT and early endoscopy. An endoscopic approach with the introduction of a fully coated metal stent was chosen as the primary solution for the esophageal perforation. Nevertheless, the patient developed other complications of perforation: mediastinitis and empyema requiring chest drainage. In addition to interventional methods, the patient was treated with broad-spectrum antibiotics and a combination of parenteral and enteral nutrition. After 3 months of treatment and resolving the complications, the patient was released to outpatient care in a good clinical condition.

The current scenario shows that the most of the road accidents are occurring due to drunk-driving. The drivers who drink alcohol are not in a stable condition and so, rash driving occurs on highway which can be risky to the lives of the people on road, the driver inclusive. This paper presenting an Experimental Analysis of Alcohol detection in open and closed vehicle. (Here we used Royal Stage and Royal Challenge whisky). Here we set the alcohol limit 180 ml to the sensor and reading is taken on 60,120 and 180 ml. After testing, it is observed that when the alcohol quantity is 120ml, we can allow the driver to drive but when the quantity more than 180ml, the buzzer sound and the reading observed above the set limit. The performance testing found by us is satisfactory in both open and closed car .There are so many technics of alcohol detection available but here we are giving practical approach. It will definitely be effective and beneficiary to the society.
