Authors: Zerebiec Katherine , Carey Magalie , Kolb Noah , Lamoy Tracy , Dubey Divyanshu , Hehir Michael
Published: May 2023

A 46-year-old, previously healthy woman presented via telemedicine with 14 months of progressive asymmetrical weakness, numbness, paresthesias and tremors. History and clinical exam findings suggested a peripheral etiology resembling a variant CIDP presentation. Electrodiagnostic testing identified only one motor nerve with signs of demyelination; the remainder of motor and sensory nerves were unable to be evoked. MRI showed diffuse enhancement of the trigeminal nerve and cauda equina. CSF revealed albuminocytologic dissociation. The patient was treated empirically with methylprednisolone for a clinically suspected variant of CIDP, more specifically a nodo-paranodopathy. Two weeks after initiation of steroid treatment, cerebrospinal fluid and serum yielded antibodies to contactin-1 which coincided with our clinical suspicion for an autoimmune nodo-paranodopathy, which is known to be refractory to IVIG. Rituximab was added given the patient’s severe presentation at the time of diagnosis. The autoimmune nodo-paranodopathies are treatable, even in the case of a severe presentation. Lack of clinician awareness and delay in diagnosis can be detrimental as in the case of our nearly paralyzed patient. It is important to raise awareness of the disease, its presentation and therapeutic management since early diagnosis and correct treatment is paramount for neurological recovery.
Evaluating Change in Student Pharmacists’ Familiarity, Attitudes, Comfort, and Knowledge as a Result of Integrating Digital Health Topics Into a Case Conference Series: Cohort Study
Authors: Darnell Julia C , Lou Mimi , Goldstone Lisa W
Published: May 2023

Background

The use of technology in health care, often referred to as digital health, has expanded rapidly because of the need to provide remote care during the COVID-19 pandemic. In light of this rapid boom, it is clear that health care professionals need to be trained in these technologies in order to provide high-level care. Despite the growing number of technologies used across health care, digital health is not a commonly taught topic in health care curricula. Several pharmacy organizations have called attention to the need to teach digital health to student pharmacists; however, there is currently no consensus on best methods to do so.

Objective

The objective of this study was to determine if there was a significant change in student pharmacist scores on the Digital Health Familiarity, Attitudes, Comfort, and Knowledge Scale (DH-FACKS) after exposure to digital health topics in a yearlong discussion–based case conference series.

Methods

Student pharmacists’ initial comfort, attitudes, and knowledge were gathered by a baseline DH-FACKS score at the beginning of the fall semester. Digital health concepts were integrated into a number of cases in the case conference course series throughout the academic year. The DH-FACKS was administered again to students after completion of the spring semester. Results were matched, scored, and analyzed to assess any difference in DH-FACKS scores.

Results

A total of 91 of 373 students completed both the pre- and postsurvey (response rate of 24%). Using a scale from 1 to 10, the mean student-reported knowledge of digital health increased from 4.5 (SD 2.5) before intervention to 6.6 (SD 1.6) after intervention (P<.001) and the mean self-reported comfort increased from 4.7 (SD 2.5) before intervention to 6.7 (SD 1.8) after intervention (P<.001). There was a significant increase in scores for all 4 elements of the DH-FACKS. The mean familiarity scores increased from 11.6 (SD 3.7) to 15.8 (SD 2.2), out of a maximum of 20 (P<.001). The mean attitudes scores increased from 15.6 (SD 2.1) to 16.5 (SD 1.9), out of a maximum of 20 (P=.001). The mean comfort scores increased from 10.1 (SD 3.9) to 14.8 (SD 3.1), out of a maximum of 20 (P<.001). The mean knowledge scores increased from 9.9 (SD 3.4) to 12.8 (SD 3.9), out of a maximum of 20 (P<.001).

Conclusions

Including digital health topics in a case conference series is an effective and approachable way of providing education on important digital health concepts to students. Students experienced an increase in familiarity, attitudes, comfort, and knowledge after the yearlong intervention. As case-based discussions are an important component of most pharmacy and other medical curricula, this method can be easily applied by other programs that wish to give their students practice applying their knowledge of digital health to complex case-based scenarios.
Potential Use of ChatGPT in Responding to Patient Questions and Creating Patient Resources (Preprint)
Authors: Reynolds Kelly , Tejasvi Trilokraj
Published: May 2023

UNSTRUCTURED

ChatGPT (OpenAI) is an artificial intelligence–based free natural language processing model that generates complex responses to user-generated prompts. The advent of this tool comes at a time when physician burnout is at an all-time high, which is attributed at least in part to time spent outside of the patient encounter within the electronic medical record (documenting the encounter, responding to patient messages, etc). Although ChatGPT is not specifically designed to provide medical information, it can generate preliminary responses to patients’ questions about their medical conditions and can precipitately create educational patient resources, which do inevitably require rigorous editing and fact-checking on the part of the health care provider to ensure accuracy. In this way, this assistive technology has the potential to not only enhance a physician’s efficiency and work-life balance but also enrich the patient-physician relationship and ultimately improve patient outcomes.
An Escape Game on University Students’ Mental Health During the COVID-19 Pandemic: Cocreation Study (Preprint)
Authors: Labrosse David , Vié Clara , Hajjam Hana , Tisseron Clément , Thellier Dimitri , Montagni Ilaria
Published: May 2023

BACKGROUND

The COVID-19 pandemic has had a severe impact on students’ mental health. Interventions are needed to promote their psychological well-being and prevent mental illnesses in the aftermath of this unprecedented situation. Digital escape games can be an effective tool to support students’ mental health. A cocreation approach can improve the acceptability of these interventions by involving different stakeholders (eg, end users, game designers, and health professionals) to obtain audience-specific games.

OBJECTIVE

This study aims to describe the process of testing and optimizing the game “EscapeCovid” on students’ mental health, to serve as a model for the cocreation of future similar interventions.

METHODS

The PRODUCES (Problem, Objective, Design, End Users, Cocreators, Evaluation, Scalability) framework was used. Cocreation steps (test and optimization) were detailed for replicability. A total of 45 students tested a pilot version of the game, with 10 undergoing a semistructured interview. Meetings with a group of stakeholders and brainwriting were organized to optimize the game.

RESULTS

We produced a new version of the game incorporating the suggestions provided by student testers and following the stakeholders’ guidelines. Improvements were made to both the content and the form of the new version of the pilot game. The storyline, including the protagonist and the scenes, was adapted to the student population.

CONCLUSIONS

Our results suggested that cocreation can contribute to the design of more widely accepted interventions aimed at promoting mental health and preventing psychological disorders. Results also suggest that an end user–centered approach can facilitate intervention tailoring. When conceiving a health-related escape game for students, we recommend using the cocreation approach to enhance players’ experience, thus positively influencing their learning process and overall well-being.
Comprehensive Ontology of Fibroproliferative Diseases: Protocol for a Semantic Technology Study (Preprint)
Authors: Golec Marcin , Kamdar Maulik , Barteit Sandra
Published: May 2023

BACKGROUND

Fibroproliferative or fibrotic diseases (FDs), which represent a significant proportion of age-related pathologies and account for over 40% of mortality in developed nations, are often underrepresented in focused research. Typically, these conditions are studied individually, such as chronic obstructive pulmonary disease or idiopathic pulmonary fibrosis (IPF), rather than as a collective entity, thereby limiting the holistic understanding and development of effective treatments. To address this, we propose creating and publicizing a comprehensive fibroproliferative disease ontology (FDO) to unify the understanding of FDs.

OBJECTIVE

This paper aims to delineate the study protocol for the creation of the FDO, foster transparency and high quality standards during its development, and subsequently promote its use once it becomes publicly available.

METHODS

We aim to establish an ontology encapsulating the broad spectrum of FDs, constructed in the Web Ontology Language format using the Protégé ontology editor, adhering to ontology development life cycle principles. The modeling process will leverage Protégé in accordance with a methodologically defined process, involving targeted scoping reviews of MEDLINE and PubMed information, expert knowledge, and an ontology development process. A hybrid top-down and bottom-up strategy will guide the identification of core concepts and relations, conducted by a team of domain experts based on systematic iterations of scientific literature reviews.

RESULTS

The result will be an exhaustive FDO accommodating a wide variety of crucial biomedical concepts, augmented with synonyms, definitions, and references. The FDO aims to encapsulate diverse perspectives on the FD domain, including those of clinicians, health informaticians, medical researchers, and public health experts.

CONCLUSIONS

The FDO is expected to stimulate broader and more in-depth FD research by enabling reasoning, inference, and the identification of relationships between concepts for application in multiple contexts, such as developing specialized software, fostering research communities, and enhancing domain comprehension. A common vocabulary and understanding of relationships among medical professionals could potentially expedite scientific progress and the discovery of innovative solutions. The publicly available FDO will form the foundation for future research, technological advancements, and public health initiatives.

Examining the efficacy of a digital ACT intervention for the improvement of self-management behaviours and psychological flexibility in adults with cardiac disease: A single case experimental design and qualitative investigation (Preprint)
Authors: Moran Orla , Doyle Julie , McHugh Louise , Giggins Oonagh , Smith Suzanne , Gould Evelyn , Lavelle Joseph
Published: May 2023

BACKGROUND

Cardiovascular disease remains the leading cause of death worldwide with research showing that psychological distress increases the risk for poorer disease outcomes, including self-management behaviours, and mortality. Digital health platforms offer increased availability and flexibility to individuals wishing to access therapeutic support who may not be able to access in-person therapy, and as well as supporting condition self-management. Acceptance and Commitment Therapy (ACT) has consistently demonstrated positive outcomes in those with chronic health conditions, however most empirical investigations conducted to date also involve in-person therapy.

OBJECTIVE

This research aimed to examine the efficacy of a digital ACT intervention to improve self-management behaviours and psychological flexibility in cardiac patients

METHODS

The intervention was delivered via a digital health application (app) over five weeks per participant with once weekly live video one-to-one sessions with nine cardiac patients (M=55.55yrs; SD=6.81yrs; 6 males). A mixed methods design was used. Quantitative analysis involved a randomized-multiple baseline Single Case Experimental Design (SCED). The Independent Variable for each participant is pre- post intervention phase. Dependent variables are daily self-report measures of psychological flexibility, as well as objective measures of self-management. Qualitative analysis involved one-to-one interviews and further examined participants’ experience of the intervention.

RESULTS

While quantitative outcomes did not reveal any significant improvements, qualitative findings gave support to the intervention as a viable means of managing distress and improving self-management behaviour, as well as identifying several contributions to supporting people with cardiac disease.

CONCLUSIONS

Although findings give partial support to the use of a digital ACT intervention to improve self-management behaviours and psychological flexibility in cardiac patients, further research is needed.

Este artículo dilucida quiénes fueron los provocadores de esta violencia, por qué los directores del texto consideraron necesario mostrar a través de imágenes el fuego y la sangre, y cómo se dio la simbiosis entre narración e imagen.
La construcción simbólica de la unidad partidista para la elección del Estado de México (2023)
Authors: Arteaga Nelson
Published: May 2023

Se analiza la competencia por el sentido civilmente puro e impuro de las candidatas a la gubernatura del Estado de México (2023-2029). Mediante la sociología cultural se explora la conformación de estructuras de clasificación cultural de instituciones comunicativas —columnas de opinión—, que definen a las candidatas como correas de transmisión de virtudes y defectos de sus líderes, grupos y facciones que representan, así como de sus distintos proyectos políticos. Este esfuerzo por dar sentido simbólico a la designación revela la insuficiencia de acuerdos cupulares para construir una candidatura potencialmente competitiva, que sólo pueden ser operados en estructuras culturales profundas.

Authors: S. PRASANNA , MAHAJAN MAYURI , DAS NIKUNJA KUMAR , MAHAJAN NIKHIL , S. CHANDANA
Published: May 2023

Nocardia infections are rare in an immunocompetent and healthy individual. It is frequently diagnosed and reported very late during the disease. Here we present an interesting case series of isolated pulmonary nocardiosis among post COVID-19 patients. A 45-year-old male presented to general medicine OPD with breathlessness and cough with expectoration. The patient was a known case of diabetes. A Sputum sample was sent for culture, gram, and acid-fast stain, and the nasopharyngeal swab was sent for RT-PCR and turned out to be COVID-19 negative. Gram stain showed numerous pus cells with filamentous hyphae-like structures. Nocardiosis was strongly considered based on imaging morphology. A 65-year-old female presented to OPD with fever, respiratory distress, and expectorating cough for one month. The patient was a not known case of diabetes and hypertension. The patient was diagnosed with pneumonia and had a history of COVID-19. The microscopic examination of the sputum sample revealed no fungal elements. The Gram and Ziehl-Neelsen stain showed pus cells with filamentous bacilli and no acid-fast bacilli. A 50-year-old male presented to general medicine OPD with breathlessness and expectorating cough for four weeks. The patient was a not known case of diabetes and hypertension. The sputum sample was negative for ZN stain; the Gram stain showed numerous pus cells with filamentous hyphae-like structures. The modified acid-fast staining was done for sputum and BAL samples in all cases showed filamentous weak acid-fast bacilli resembling Nocardia species. The patient did well with cotrimoxazole and was discharged later. The differential diagnosis of nocardia should always be in mind in case of lung infections. All respiratory samples must also be screened for Nocardia. The early diagnosis and management of pulmonary nocardiosis decide the patient’s prognosis.

Authors: JAGADEESAN UMAMAHESWARI , MANAVALAN JAYAVARTHINNI , SRI NSK ROOBHINI , BANAJI NANDITA
Published: May 2023

Objective: This study was done to evaluate the susceptibility of Staphylococcus aureus to mupirocin and to determine the antimicrobial susceptibility pattern of Staphylococcus aureus among various clinical isolates.
Methods: All the consecutive, non-duplicative Staphylococcus aureus isolates collected during the year 2020 were subjected to the disk diffusion method to evaluate the antimicrobial susceptibility pattern and were stocked. Mupirocin susceptibility for all stocked Staphylococcus aureus was detected by Minimal inhibitory concentration (MIC) determination by Epsilometer test (E-test).
Results: The total number of Staphylococcus aureus was 52. The maximum number of Staphylococcus aureus was isolated from pus sample 40 (76.9%). Among the 52 isolates, 26 (50%) were found to be methicillin-resistant Staphylococcus aureus (MRSA). All the isolates were susceptible to tetracycline (100%), vancomycin (100%), teicoplanin (100%), and linezolid (100%). By E-test, the overall prevalence of mupirocin resistance was 63.5%. Low-level Mupirocin resistance (MupRL) of 8-256 µg/ml was 59.6% and high-level mupirocin resistance (MupRH) of ≥512 µg/ml was 3.9%.
Conclusion: The present study shows a high prevalence of mupirocin resistance (63.5%) which is a serious concern. Therefore, indiscriminate use of topical mupirocin in carriers is not advisable. It may be recommended only in case of an outbreak of skin and soft tissue infection attributed to Staphylococcus aureus.

Authors: Kumar Anshu , Bharti Pankaj Kumar
Published: May 2023

The practice of meditation has been associated with a wide range of positive physiological and psychological effects, such as reduced stress, improved emotional regulation, and increased overall well-being. In this research, the procedure of meditation that eliminates psychosomatic disorders is investigated. Psychosomatic disorders impact the mind and body. Mental disorders like stress and anxiety can lead to physical diseases like chronic pain and muscle dysfunction. This article investigates the possibility of meditation being used as a remedy for psychosomatic disorders. Examining existing literature on the topic reveals that meditation has been demonstrated to reduce stress and anxiety levels, enhance immune system functioning, and promote emotional regulation. The evidence suggests that meditation could be a possible alternative treatment for psychosomatic problems. This study discusses the mechanisms of Vipassanā and Yoga meditation techniques. The paper further highlights the necessity of seeking medical counsel and treatment and utilising meditation as an element of a comprehensive care approach instead of a stand-alone remedy. Overall, the paper indicates that meditation may be a helpful aid for controlling the symptoms of psychosomatic disorder, and it emphasises the need for additional research on the subject.

Published: May 2023

There is growing consensus among the social scientist that for the development of rural economy, rural non-farm sector should be thriving. The present study is an attempt to study the factors enabling the rural households of Punjab to participate in the rural non-farm activities. In the present study, the household level data of National Sample Survey Organization’s employment-unemployment 50th round and 68th round is utilized. The rural households of Punjab are categorized into; self-employed, casual labourer, regular or salary earners and others in farm as well as non-farm sector. The logit regression model for both the rounds are utilised to study the factors impacting the participation as self-employed, casual labourers, and regular wage earners in rural non-farm sector. As compared to the year 1993-94, in the year 2011-12, the proportion of households earning their livelihood in rural non-farm sector has increased. Moreover, the proportion of casual labourer in rural non-farm sector has also increased. The choice of occupations among the self-employed, regular salary earners and causal labourer in the rural non-farm sector is also changing in Punjab. The factors like education, number of skilled members in the households, head’s education, household belonging to developed districts significantly impacted the choice of working in rural non-farm sector of Punjab. The study recommends that with increase in investment in education and developing the infrastructure in rural areas can develop the rural non-farm sector.

Authors: Kuprikov Mikhail Yu. , Orekhov Alexander A. , Shulga Yelizaveta D. , Min Yan Naing
Published: May 2023

The plane has become a convenient method of transportation. The main idea of aviation in the 21st century is the safety of passengers and crew. But the human is always inclined towards comfort. The structural and parametric analysis of the long-haul aircraft development made it possible to form the concept of the fuselage layout with capsule accommodation of passengers. The proposed variant of the capsule accommodation, designed for the Boeing 777-200LR, can be installed in other passenger airliners with a ceiling height of at least 2.1 m. Analysis of alternative options for the layout of the passenger compartment allows us to state: with a flight range of more than 8 hours, the flight is comfortable only in business or first classes; the proposed two-story capsule placement allows to provide the layout with first-class seats in a given cabin.

Published: May 2023

This paper presents an improved real time target tracking system based on Cam-Shift and advanced Kalman filter algorithms. The paper, proposes a simple low implementation cost scheme while keeping the high tracking performance. Two degrees of freedom target tracking system based on two hybrid stepper motors with their drive systems is fully designed and implemented to improve the tracking accuracy while keeping low-cost. The potential of the proposed algorithm lies in its ability to accurately detect, track and produce firing commands on the designated target while utilizing low cost on the shelf embedded Microcontroller boards. A low cost Universal Serial Port (USB) camera is used and integrated with the proposed algorithm in order to detect and track maneuvering targets. A series of experiments for stationary and moving objects are carried out for testing the proposed system efficiency. The proposed system enables accurate performance for tracking static and moving objects. Hence it provides a simple and low implementation cost scheme for real time object tracking applications.

Dispatcher I-queue Optimization in Join Idle Queue Algorithm for Improved Load Balancing in Cloud Computing
Authors: Narang Sudha
Published: May 2023

Objectives: Modern data centers serving web and mobile applications employ distributed load balancers. The Join Idle Queue (JIQ) algorithm is ideally suited for load balancing in a distributed setup. It attains fast response time by directing service requests to idle servers which can immediately process them. However, JIQ is not optimal in tracking idle servers leaving room for improvement.

Methods: We observed that JIQ assigns idle servers non-uniformly to load balancers leaving some load balancers with no access to idle servers. We propose a variant of the JIQ algorithm, Join Idle Queue Dispatcher I-queue Optimization (JIQ-DIO), which increases the probability of load balancers having access to idle servers without additional communication overhead leading to improved response time.

Findings: We simulated JIQ-DIO on CloudSim Plus 3.0 and compared it with standard JIQ and its different variants. JIQ-DIO was found to increase the probability of incoming requests being directed to idle servers and lead to more than two-fold improvement in response time across a broad range of parameters.

Mitigation and Detection of DDOS attacks using Software Defined Network (SDN) and Machine Learning
Authors: R L Hemanth kumar , K P Bhargava , A R Dr. Ashok Kumar
Published: May 2023

Abstract: An emerging networking paradigm called Software Defined Networking (SDN) enables network control to be restricted to a logically centralized controller. This makes network visibility and management simpler on a global scale. SDN is a suitable network model for extensive deployment in real-world settings since it can be programmed using high-level programming languages. SDN is still vulnerable to a number of network attacks, the most notable of which being the DDoS (distributed denial of service) attack. A DDoS attack has the potential to render the controller, the brain of SDN, inoperable. SDN security is still in its infancy, and both business and academics have done a lot of research in this area. The SDN DDoS mitigation strategy utilizing machine learning (ML) is the main topic of this study. This work also surveys network traffic aspects for DDoS detection

Abstract: Recently, biometric was being integrated with cryptography (crypto-biometric system) to alleviate the limitations of the biometric or cryptography system. However, the main shortcoming of cryptography is poorly-chosen or forgotten password while challenges with biometrics include interclass similarities in the feature sets used to represent traits. In this work, a combination of cryptography and bimodal biometric was developed, an Advanced Encryption Standard based Fast Fourier Transform (AES-FFT) was developed and used as the cryptography technique. Hence, an attempt was made to develop an improved access control system using an enhanced bimodal bio-cryptography. Biometric features was extracted from individual face and iris after application of suitable preprocessing techniques for each modality using Principal Component Analysis (PCA) while cryptography key was generated using fused features from the face and iris by Advanced Encryption System based Fast Fourier Transform (AES-FFT). The two captured biometric data at acquisition module via webcam were subjected to appropriate pre-processing and feature extraction module. The features extracted were fused at feature level using weighted average and optimal features were selected using genetic programming (GP). The classification technique used was Support Vector Machine (SVM).
Real-World Analysis of Smart City Integrated Services using High-Speed Network Technologies
Authors: P Bhargava K , P Suyog , Nagaraja G S
Published: May 2023

Abstract: Services for smart cities are required to improve productivity, sustainability, and quality of life. They can maximise resource usage, enhance public safety, accelerate economic growth, and promote civic engagement. In the past, cities relied on unreliable and limited-range radio and wired telephone networks. The capabilities of networked city services have significantly increased with the development of technologies like Ethernet and passive optical network (PON). These technologies enable real-time data collecting and analysis by delivering higher data transfer speeds and greater coverage areas. PON connections offer higher bandwidth, greater reliability, and longer lifetimes; 50 Gigabit-PON has the capacity to support different commercial services with notable performance to meet service requirements; and Ethernet networks have lower deployment costs as well as greater flexibility in terms of adding or removing devices. The various use-case scenarios of high-speed network technologies are evaluated.

Abstract: The world including India have faced a lot of difficulties passing through Covid-19 waves not only once, but for several times which has also given a big threat to the world economy and human lives. Different waves have disrupted the lives and livelihood of the people. As per views of scientists the Covid-19 virus is something unique which has been changing its form from time to time. Recently, in March, 2023, it has come to light that Corona virus again has come in the name of “XBB.1.5” with 89.6% of affected cases. This small piece of study is based on the marginal class of people who are selling their products from door-to-door and small scale entrepreneurs. The main objective of the paper is to draw the attention of researchers and readers on the business threats and sufferings of small scale business personnel and daily sellers. The research is done on the basis of face-to-face interviews with their photos in order to share the experience the interviewees earned during different phases of Covid-19. This paper is concluded with a common view of those simple folk that this virus would never perish from this world, but we have to take timely precautionary measures to be protected from the virus.

Abstract: Diabetic retinopathy (DR) is a leading cause of blindness in diabetic patients. Early detection and classification of DR can facilitate timely treatment and reduce the risk of vision loss. In recent years, deep learning has shown promise in automating the diagnosis of DR. However, the use of high-performance models such as ResNet and DenseNet often requires powerful computing resources and large amounts of data. In this study, we propose a deep learning approach for the detection and classification of DR using MobileNetV2, a lighter and more computationally efficient model. Our method was trained and tested on a large publicly available dataset, achieving an accuracy of 85.28% for DR classification. We also conducted experiments to investigate the importance of different hyperparameters and data augmentation techniques. The results demonstrate the effectiveness of our method in detecting and classifying DR with high accuracy while using fewer computational resources. The proposed method has the potential to be applied in clinical settings to assist ophthalmologists in the early detection and diagnosis of DR.

Abstract: For end users to access various systems, services, and applications, multimedia data sharing is increasingly becoming an essential part of their daily lives. Cloud storage services in the real world frequently disclose data. In secure data transfer media, authenticity and copyright protection of multimedia content have always been a concern. As more people use the Internet and digital technologies, the issue has become more serious. Creating copyright protection, on the other hand, is more difficult and complicated. In proposed approach both Watermarking and Intermediary Re-encryption (PRE) approach used for productive mixed media content sharing. Watermarking is accustomed to concealing the data, for example, conceal privileged intel in computerized media like pictures. Data security is provided by encryption methods. In proposed work, secret key can be encoded utilizing encryption calculation with the assistance of key. The user's private key is then combined with the encrypted key information and can be embedded using LSB (Least Significant Bit) in the image or audio. The ECC Encryption algorithm can be used to encrypt an image or audio after secret information has been embedded. Finally, the embedded data verification process enables authorized users to extract the decryption key. When user information does not correspond with embedded information, illegal or unauthorized access can be identified. Furthermore, Block chain technology is used to safeguard these transaction details.

Abstract: The current storage mechanism currently stores user data on cloud servers. Thus, users give up their rights. You don't have control over the data and run the danger of privacy violations. Encryption technology is often the cornerstone of the traditional privacy protection strategies even if it is not very effective at thwarting assaults from within a cloud server because it cannot be fully analyzed from within. This paper's goal is to offer a fog computing-based three-layer storage structure for resolving the cloud storage issue. Frameworks like the one this study suggests can be utilized to fully utilize cloud storage while preserving user privacy. The Hash-Solomon coding technique also enables the segmentation of data. Then, to ensure privacy, a small amount of data can be stored on local computers and fog servers. The theoretical safety study and experimental assessment have demonstrated the feasibility of our proposal, which is a major advance over the existing cloud storage method. If one data component is missing, all the data information is lost. We shall demonstrate the effectiveness of the system as we secure it. Using this computational intelligence-based method, it is also possible to calculate the distribution percentage that is stored in clouds, fog, and local computers. Through theoretical safety analysis and experimental evaluation, our strategy— which represents a significant improvement over the current cloud storage strategy—has been demonstrated to be workable. If one data component is missing, all the data information is lost. Additionally, the distribution fraction saved can be determined thanks to the computational intelligence employed in this method.

Abstract: As there is an increase in the usage of digital applications, the availability of data generated has increased to a tremendous scale. Data is an important component in almost every domain where research and analysis are required to solve problems. It is available in a structured or unstructured format. Therefore, to get corresponding data as per the application purpose, easily and quickly from different sources of data on the internet, an online content summarizer is desired. Summarizers make it easier for users to understand the content without reading it completely. Abstractive Text Summarizer helps in defining the content by considering the important words and helps in creating summaries that are in a human-readable format. The main aim is to make summaries in such a way that they should not lose their context. Various Neural Network models are employed along with other machine translation models to bring about a concise summary generation. This paper aims to highlight and study the existing contemporary models for abstractive text summarization and also to explore areas for further research
