Post-Quantum Encryption Benchmark

Recent advancements in quantum computing bring the weaknesses in modern RSA encryption to the foreground. Shor\u27s algorithm, though not implementable on today\u27s quantum computers, shows that RSA asymmetric key encryption is not secure for the coming future. This flaw in the security has prompted the National Institute of Standards and Technology (NIST) to start a search for a new post-quantum encryption algorithm that will be resistant to future quantum computers. There are several implementations of preforming this encryption scheme. One promising technique is using lattices in an application called ring Learning with Errors (rLWE). Several algorithms have been submitted to NIST for post-quantum encryption. This paper covers the speed differences of different implementations of rLWE algorithms that have made it past the NIST round two post-quantum submissions on a desktop processor and an embedded system

A Comprehensive Survey on Data Utility and Privacy: Taking Indian Healthcare System as a Potential Case Study

The authors would like to thank the anonymous reviewers and editors who have been involved in examining this manuscript.Background: According to the renowned and Oscar award-winning American actor and film director Marlon Brando, “privacy is not something that I am merely entitled to, it is an absolute prerequisite.” Privacy threats and data breaches occur daily, and countries are mitigating the consequences caused by privacy and data breaches. The Indian healthcare industry is one of the largest and rapidly developing industry. Overall, healthcare management is changing from disease-centric into patient-centric systems. Healthcare data analysis also plays a crucial role in healthcare management, and the privacy of patient records must receive equal attention. Purpose: This paper mainly presents the utility and privacy factors of the Indian healthcare data and discusses the utility aspect and privacy problems concerning Indian healthcare systems. It defines policies that reform Indian healthcare systems. The case study of the NITI Aayog report is presented to explain how reformation occurs in Indian healthcare systems. Findings: It is found that there have been numerous research studies conducted on Indian healthcare data across all dimensions; however, privacy problems in healthcare, specifically in India, are caused by prevalent complacency, culture, politics, budget limitations, large population, and existing infrastructures. This paper reviews the Indian healthcare system and the applications that drive it. Additionally, the paper also maps that how privacy issues are happening in every healthcare sector in India. Originality/Value: To understand these factors and gain insights, understanding Indian healthcare systems first is crucial. To the best of our knowledge, we found no recent papers that thoroughly reviewed the Indian healthcare system and its privacy issues. The paper is original in terms of its overview of the healthcare system and privacy issues. Social Implications: Privacy has been the most ignored part of the Indian healthcare system. With India being a country with a population of 130 billion, much healthcare data are generated every day. The chances of data breaches and other privacy violations on such sensitive data cannot be avoided as they cause severe concerns for individuals. This paper segregates the healthcare system’s advances and lists the privacy that needs to be addressed first

A survey on security and privacy issues in IoV

As an up-and-coming branch of the internet of things, internet of vehicles (IoV) is imagined to fill in as a fundamental information detecting and processing platform for astute transportation frameworks. Today, vehicles are progressively being associated with the internet of things which empower them to give pervasive access to data to drivers and travelers while moving. Be that as it may, as the quantity of associated vehicles continues expanding, new prerequisites, (for example, consistent, secure, vigorous, versatile data trade among vehicles, people, and side of the road frameworks) of vehicular systems are developing. Right now, the unique idea of vehicular specially appointed systems is being changed into another idea called the internet of vehicles (IoV). We talk about the issues faced in implementing a secure IoV architecture. We examine the various challenges in implementing security and privacy in IoV by reviewing past papers along with pointing out research gaps and possible future work and putting forth our on inferences relating to each paper

Effect of heat shock on hilA expression in Salmonella Typhimurium

The effect of heat shock was observed on the expression of hilA in Salmonella Typhimurium by creating a fluorescence-based reporter strain of Salmonella and by realtime reverse transcriptase polymerase chain reaction (RT-PCR). The hilA gene in Salmonella is known to play an important role in its pathogenesis. hilA is known to be activated when the bacteria encounter stress-inducing conditions. A number of factors have been identified that affect hilA expression, such as, pH, osmolarity, oxygen tension. When Salmonella enter their warm-blooded hosts, they encounter an increase in temperature. Therefore, heat is another stressor that is encountered by Salmonella during infection of their hosts. A fluorescence-based strain of Salmonella was created to study the effect of heat shock. The gene for green fluorescent protein (gfp) was placed under the control of the promoter of hilA on a plasmid. This plasmid was used to transform Salmonella cells to create a fluorescent strain. In this strain, when the hilA promoter is activated, gfp is transcribed, which encodes the green fluorescent protein. This protein can be measured by a fluorescence assay. The results of this study indicated that at 45ºC, hilA is activated. RT-PCR was used to look at hilA expression at different temperature. The results of this study indicated that, compared to 37ºC, higher temperatures like 45ºC and 55ºC significantly activate hilA

Prospective Assessment of Prescribing Pattern of Intravenous Proton Pump Inhibitors in an Indian Tertiary-Care Teaching Hospital

ABSTRACT Context: Inappropriate use of intravenous proton pump inhibitors (IV PPIs) has been a major challenge for private health-care setups. Inappropriate prescribing may result in increased shortages of IV PPIs in hospitals, therapeutic burden, adverse effects, and treatment costs. Therefore, the study was sought to determine drug utilization patterns (appropriateness and inappropriateness) of IV PPIs in an Indian tertiary-care teaching hospital. Aims: To assess the drug utilization pattern of IV PPIs in a tertiary-care teaching hospital. Settings and Design: This was a prospective observational study. Methods and Material: This study was conducted over a period of one month. Patients who were ≥18 years of age, who were admitted in the internal medicine, surgery, or gastroenterology wards, and who were receiving IV PPIs were included in the study. Paediatric patients and outpatients were not enrolled in the study. Ddemographics, past medication and surgery, current medical condition and medication, dose, dosing interval, duration of therapy, length of stay, and endoscopic details of each patient was collected from patients' case notes, treatment charts, and laboratory/diagnostic test reports, and evaluated for appropriateness regarding indication. Statistical analysis: Chi square test (χ 2 ) was used to analyze the data. Results: Prospective assessment involved 611 patients over a 1-month period. For prophylaxis (stress ulcer, pre-operative and postoperative prophylaxis) and treatment, IV PPIs were prescribed inappropriately to 289 (89.2%) internal medicine and 97 (34.04%) surgery ward patients. Prolonged therapy was found in patients who received IV PPIs for stress ulcer prophylaxis. Conclusion: This study revealed significant inappropriateness of PPI administration with particular reference to indication to use, duration of therapy, and changeover of therapy in an Indian tertiary-care teaching hospital

AVALIAÇÃO DO ESTADO NUTRICIONAL DA S PESSOA S AT ENTIDOS EM UM CENTRO DE HEMODIÁLISE EM MONTEVIDEU.

Due to the importance of nutritional status in all stages of life, particularly in some pathologies, this article seeks to assess the nutritional status of people with chronic kidney disease who attend the hemodialysis center in Montevideo in April, 2014. A descriptive, cross-sectional study was selected, in which 47 patients undergoing hemodialysis were analyzed using anthropometric and biochemical markers. It was found that 38% of them had some form of malnutrition: 30% were overweight and/or obese, and out of the 32% that were normally nourished, 60% had nutritional risk for central distribution of fat. Patients who spent more time on hemodialysis have more probability of becoming malnourished or undernourished.Debido a la importancia del estado nutricional en todas las etapas de la vida, y en especial bajo algunas patologías, se plantea como objetivo valorar el estado nutricional de personas con enfermedad renal crónica que asisten al centro de hemodiálisis en la ciudad de Montevideo en abril del 2014. Se seleccionó un estudio descriptivo, de corte transversal en el que se estudió a través de indicadores antropométricos y bioquímicos a 47 personas que se realizan hemodiálisis. Se obtuvo que el 38% de las personas presentaban algún tipo dedesnutrición: el 30% presentaban sobrepeso y/u obesidad, y del 32% de las personas que se encontraban normonutridos, el 60% presentaba riesgo nutricional por distribución central de grasa. Se detectó que coexisten la malnutrición por déficit como por exceso, predominando la desnutrición. Las personas con mayor tiempo en hemodiálisis presentan malnutrición por déficit o desnutrición en mayor proporción que los que hace menos tiempo que se dializan.ABSTRACTDue to the importance of nutritional status in all stages of life, particularly in some pathologies, this article seeks to assess the nutritional status of people with chronic kidney disease who attend the hemodialysis center in Montevideo in April, 2014.

Mix method approach of measuring VR as a pedagogical tool to enhance experimental learning: Motivation from literature survey of previous study

This research has been experimented on our previous literature review. Technological advancement has prevailed in the modern era from the 20th century. Artificial intelligence and virtual worlds have been created for rapid technological development. This paper is aimed at exploring the effect of virtual reality as a pedagogical tool for enhancing experiential learning among undergraduate students. Considering this, it was a mixed-methods study following the design of sequential exploratory–which includes qualitative followed by quantitative part. The targeted population was undergraduate students taking education programs from Public Sector Universities of Sindh. For the qualitative part, the sample of eight undergraduate students was interviewed for exploring their perceptions about virtual reality for enhancing experiential learning. The interviewed data were thematically analyzed, which revealed seven themes. For the quantitative part, emerged seven themes were used as constructs for developing the questionnaire. It was then used for quantitative data collection having excellent reliability. A sample of 80 students was taken, and data were collected by self-administration. The quantitative data were analyzed by descriptive as well as inferential statistics. Hence, the results found a statistically significant effect of virtual reality for enhancing experiential learning. However, user-friendliness ensures the applicability of virtual reality. Thus, it concluded that the implementation of virtual reality influences experiential learning enhancement. However, the implementation of virtual reality still depends upon the user-friendly nature of technology and virtual reality
