Opowiedzieć Uniwersytet. Łódź akademicka w biografiach wpisanych w losy Uniwersytetu Łódzkiego
Authors: Kaźmierska Kaja , Waniek Katarzyna , Zysiak Agata
Published: June 2022

Książka powstała na podstawie wspomnień powojennej generacji studentów, a następnie nauczycieli akademickich, którzy reprezentują różne dyscypliny: humanistykę, nauki społeczne, nauki przyrodnicze i nauki ścisłe. Przez pryzmat indywidualnych doświadczeń pokazane zostały istotne procesy społeczne, polityczne i uwarunkowania historyczne kształtujące na przestrzeni dekad ideę „univeristas” (wspólnoty wartości). W przedstawionych wspomnieniach Czytelnik znajdzie zatem: ślady ważnych wydarzeń historycznych; opisy i komentarze pomocne w rekonstrukcji dynamiki przemian świata akademii w jego wymiarze edukacyjnym, naukowym i badawczym; materiał umożliwiający konfrontację niedawnej przecież przeszłości z teraźniejszością życia uniwersyteckiego. Każdorazowe odwołanie się do czasu studiów niejednokrotnie sprzyja porównaniu tamtego uniwersytetu ze współczesnym. Publikacja zwraca uwagę na znaczenie analiz biograficznych i historii mówionej dla badań nad nauką, a także pokazuje, jak prowadzić je w sposób rzetelny. Podkreślić należy, że miejscem, w którym powstała, jest Łódź – główne centrum polskich badań biograficznych.

Published: June 2022

Background: Organic trace minerals can improve the improve the bioavailability and reduce the environmental pollution, but the effect of organic trace minerals on meat quality of pigs are still unclear. Methods: Adult healthy 33.68 kg pigs (n = 253) were randomly allotted to six dietary treatments, with 6 pens per treatment and 7-8 pigs per pen in a completely randomized design: 1) ITM: inorganic trace minerals with 20, 100, 40 and 60 mg/kg of Cu, Fe, Mn and Zn in sulfate form; 2) T1: ITM was replaced with 20% mineral methionine hydroxy analog chelate (MMHAC); 3) T2: ITM was replaced with 40% MMHAC; 4) T3: ITM was replaced with 60% MMHAC; 5) T4: ITM was replaced with 80% MMHAC; 6) T5: ITM was replaced with 100% MMHAC. Result: In the present study, shoulder fat thickness, the 6th to 7th rib fat thickness (P less than 0.05), the 10th rib fat thickness, the last rib fat thickness and lumbosacral fat thickness tended to decrease with the increase of the MMHAC. In addition, MMHAC increased pH by 1.05~3.68% and reduced drip loss by 5.08~19.77% and cooking loss by 2.67~7.67% compared with the ITM group. Furthermore, MMHAC reduced methionine by 3.51~7.02%, phenylalanine by 1.14~3.41%, arginine by 1.52~3.79% compared with ITM group. Our results showed that MMHAC improved carcass traits, meat quality and meat flavor partly compared with the ITM group.

Published: June 2022

Background: Pests and diseases infestations reduce the quantity and quality of seed yields. The objective of this study was to identify the correlation value between level of resistance to pests and chemical (fat and protein) concentrations of soybean genotypes. Methods: A total of 15 soybean genotypes were planted in field and glass house environments in 2017. Observations were made on the infestation intensity of pest and disease, dry seed yield, yield components and chemical (fat and protein) concentrations. Result: Soybean genotype DG-91-8 showed resistant (R) category to pod borer and pod sucker, while DM-122-35-17 showed resistant (R) category to army worm and pod borer. Two highest yielding genotypes (DG-91-8 and DG-99-32-14) had 15% higher seed yield than check variety Dering 1 (2.41 t/ha), with higher 100 seeds weight and pod number/plant. Fat concentration showed a significant positive correlation value with leaf rust disease. Pod suckers showed a significant positive correlation value with pod borer infestation, indicating that they had the same preference for soybean pods. Soybean genotypes DG-91-8 showed high seed yield (2.70 t/ha) and resistant (R) level to pod borer and pod sucker.

The current stage of distance education development demands enhancement of standards for training of teachers working in that area. Only professional teachers are able to provide quality education for people with different abilities, interests and needs, considering their personal characteristics and specifics of distance education. It is critically important to analyse the experience and professional qualities of teachers involved in distance learning given the uniqueness of the current situation and a high probability of transition to distance education. The study was focused on establishing the actual preparedness level of teachers for distance learning and identifying prerequisites for formation of teachers’ readiness to provide students distance education.
Key words: teacher, readiness, distance education, distance learning technologies, information and communication technologies.

Characteristics contributing to low- and minimum-wage labour in Germany
Authors: Dütsch Matthias , Himmelreicher Ralf
Published: June 2022

In this article we examine the characteristics of individuals, companies, and industries involved in low-wage labour in Germany to understand their impact on the risks workers face of earning hourly wages that are below the minimum-wage and low-wage thresholds. To identify these characteristics, we use the Structure of Earnings Survey 2014 (SES). The SES is a mandatory survey of companies which provides information on wages and working hours from about 1 million jobs and nearly 70,000 compa-nies from all industries. This data allows us to present the first systematic analysis of the interaction of individual-, company-, and industry-level factors on minimum- and low-wage working in Germany. Using a descriptive analysis, we first give an overview of typical low-paying jobs, companies, and in-dustries. Second, we use random intercept-only models to estimate the explanatory power of the indi-vidual, company, and industry levels. One main finding is that the influence of individual characteristics on wage levels is often overstated: Less than 25 percent of the differences in the employment situa-tion regarding being employed in minimum-wage or low-wage jobs can be attributed to the individual level. Third, we performed logistic and linear regression estimations to assess the risks of having a minimum- or low-wage job and the distance between a worker’s actual earnings and the minimum- and low-wage thresholds. Our findings allow us to conclude that several determinants related to indi-viduals appear to suggest a high low-wage incidence, but in fact lose their explanatory power once controls are added for factors relating to the companies or industries that employ these individuals.

Uma narrativa do Brasil nas memórias e temporalidades das experiências negras no "Diário de Bitita" (1986)
Authors: Souto Amanda Moura , Freitas Matheus Silva
Published: June 2022

O presente artigo traz uma reflexão crítica das memórias e temporalidades das experiências negras brasileiras que se apresentam na obra Diário de Bitita, publicação póstuma em 1986 da escritora Carolina Maria de Jesus [1914-1977]. Buscamos explorar os contextos de sujeição e resistência presentes na obra que possibilitam discutir, por um lado, a temporalidade e as maneiras de contar sobre si e sobre o mundo que não se encerra em narrativas de dor e sofrimento e, por outro lado, o conjunto de memórias do cotidiano que é capaz de conceber uma narrativa sobre/do Brasil. A articulação temporal do passado escravocrata às experiências de opressão e desigualdades sociais e raciais encenadas em Diário de Bitita, elaboram uma narrativa que tensiona imaginários nacionais hegemônicos, entre eles a ideia de democracia racial. Ademais, a denúncia e crítica social constitutiva da obra é pavimentada por um estilo estético e poético composto de ironias, lembranças, sonhos e desejos.

Published: June 2022

A tese da educadora Pórcia Guimarães Alves é objeto deste artigo, no qual se busca compreender a confecção da pesquisa, seus vínculos com o INEP, bem como suas correlações com a agenda educacional à época. A tese debruçou-se sobre a reprovação escolar no ensino primário curitibano, tomando-a enquanto uma consequência de fatores administrativos, metodológicos, psicológicos, sociais e biológicos. Sua abordagem ao problema foi inovadora e expressou os vínculos da educadora com Anísio Teixeira, além de seu posicionamento relativamente à discussão sobre a aprovação automática dos estudantes. Ao longo do trabalho, Alves rejeitou a explicação corrente sobre a reprovação dever-se às capacidades intelectuais discente e construiu um argumento que, ao sublinhar as condições precarizadas do sistema escolar municipal, enfocou a repetência como efeito de uma justaposição de causas. Ao final da tese, Alves elaborou um experimento de ensino no Centro Educacional Guaíra, no qual examinou a quebra da seriação escolar e seu impacto na aprovação discente, situando a última enquanto condição para a implementação da aprovação automática.

PEDOT:PSS-based intrinsically soft and stretchable bioelectronics
Authors: Li Gang
Published: June 2022

Intrinsically soft and stretchable bioelectronics exhibit tissue-like mechanical behavior that enables the seamless integration of electronic devices with the human body to achieve high-quality biosignal recording and high-efficacy neural modulation. The conducting polymer poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) shows significant promise in this field because of its high conductivity, excellent biocompatibility and commercial availability. However, pristine PEDOT:PSS is brittle and rigid and thus cannot be used in soft and stretchable electronics. More effort is therefore required to engineer PEDOT:PSS into a stretchable conductor that meets the demands of bioelectronics. In this perspective, we review the recent progress and propose the possible future directions of PEDOT:PSS-based bioelectronics.

Главным направлением развития современной коммерческой авиации является не
только повышение безопасности и топливной эффективности самолeтов, но и снижение воздействия на окружающую среду, особенно по допустимому шуму на местности. Одной из идей является перенос силовой установки на верхнюю поверхность крыла для экранирования шума двигателя крылом. Такое решение может приводить к усугублению неблагоприятных явлений трансзвуковой интерференции между элементами планера, вынуждая снижать крейсерскую скорость до
числа Маха $\mathrm{M}=0.7$-$0.75$, вместо наиболее распространенной $\mathrm{M}=0.78$-$0.8$. Решение
проблемы интерференции на крейсерском режиме для малошумных компоновок
требует усовершенствования устоявшейся методики проектирования.
В данной работе представлены исследования по методике проектирования аэродинамической компоновки малошумного самолета, имеющего две особенности: двигатели расположены над задней кромкой крыла, и само крыло имеет малую стреловидность $\chi_{1/4}\sim15^\circ$ с естественной ламинаризацией обтекания (ЕЛО), при сохранении крейсерского числа $\mathrm{M}=0.78$. Получено экспериментальное подтверждение
реализуемости данной концепции.

Рассмотрены условия истечения недорасширенной сверхзвуковой струи из эксперимента LTRAC (Laboratory for Turbulent Research in Aerospace and Combustion, университет Monash, Австралия). Проведен анализ характерных параметров линейного и нелинейного переноса для струи LTRAC с использованием решений LES из ближнего и дальнего акустического поля. В обоих случаях показано выполнение условий линейного сценария переноса звука на расстояния, характерные для акустического эксперимента LTRAC. Для верификации теоретических оценок также получены численные решения сферического уравнения Бюргерса, используя начальные данные из расчета LES. Эволюционное уравнение Бюргерса решается численно в частотной области в дальней зоне до тех пор, пока эффект линейной диссипации не станет преобладающим. Решение выполняется с учетом и без учета нелинейного акустического члена, что важно для оценки влияния нелинейности на спектры аэродинамического шума в дальней зоне.
Psychology of art: art Frida Khalo’s in the formation of the mind from the cultural-historical perspective of Vygotsky
Authors: Lima Ana Ignez Belém , Oliveira Edjôfre Coelho de , Bandeira Suzanne Rocha
Published: June 2022

The study presents as object the understanding of art in the formation of the psychism under the cultural-historical perspective of Vygotsky (1991, 1999, 2004). For that, it was opted for the accomplishment of a documental bibliographical research, in order to raise bigger data and dialogues about the thematic inside the vigotskian work. It was used, for this, the book "Psychology of Art" as a starting point for such discussions following a dialectical method for the construction of new debates with the other authors presented here. Through art, the human being expresses the unconscious contents, according to a cultural-historical perspective, becoming capable of transforming himself and others through his affections. As an example, the autobiographical work of the painter Frida Kahlo stands out, bringing some of her paintings and the importance of this in her process of dealing with reality. Affectivity is presented as a fundamental element in the formation of personality, participating in the choice of the contents to be meant. Finally, it is discussed how art and affectivity act in human formation, the suppression of emotions in the current capitalist society and the need to rescue this sensibility for humanity.

Background:

The optimal treatment of displaced femoral neck fractures in patients 55 to 70 years old remains controversial. The aim of the present study was to assess the effect of closed reduction and internal fixation with cannulated screws (IF) compared with total hip arthroplasty (THA) on hip pain and function, with use of data for outcome measures, complications, and reoperations.

Methods:

This multicenter randomized controlled trial included all patients 55 to 70 years old who presented with a low-energy displaced femoral neck fracture between December 2013 and December 2018. Patients were randomly allocated to undergo either IF or THA. The primary outcome was the Harris Hip Score (HHS) at 12 months postoperatively. Secondary outcomes were the HHS at 4 and 24 months postoperatively, Oxford Hip Score (OHS), Hip Disability and Osteoarthritis Outcome Score (HOOS), health-related quality of life (EQ-5D-3L [EuroQol 5 Dimensions 3 Levels] index score and EQ-VAS [visual analogue scale]), VAS for pain, and VAS for patient satisfaction at 4, 12, and 24 months postoperatively. Complications and reoperations were continuously monitored. The primary analyses were performed according to the intention-to-treat principle.

Results:

A total of 102 patients with a mean (± standard deviation) age of 63.7 ± 4.2 years were allocated to IF (n = 51) or THA (n = 51). The mean difference in the primary outcome, the HHS at 12 months postoperatively (5.3; 95% confidence interval, 0.9 to 9.7; p = 0.017), was below the predefined minimal clinically important difference of 10 points. However, patients who underwent THA had a significantly higher HHS at 4 and 12 months, better OHS at 4 and 12 months, and better HOOS at 4, 12, and 24 months postoperatively. Patients who underwent THA also reported better health-related quality of life at 4 months postoperatively and reported greater satisfaction and less pain at 4 and 12 months postoperatively. A total of 26 patients in the IF group (51%; 95% confidence interval, 37% to 65%) and 2 patients in the THA group (4%; 95% confidence interval, 0.5% to 13%) underwent a major reoperation.

Conclusions:

In this randomized controlled trial, we showed that patients between 55 and 70 years old who underwent THA for a low-energy displaced femoral neck fracture experienced better outcomes than those who underwent closed reduction and internal fixation.

Racial Disparities in the Utilization of Shoulder Arthroplasty in the United States
Authors: Farley Kevin X. , Dawes Alexander M. , Wilson Jacob M. , Toston Roy J. , Hurt John T. , Gottschalk Michael B. , Navarro Ronald A. , Wagner Eric R.
Published: June 2022

Background:

As the incidence of shoulder arthroplasty rises at exponential rates, race is an important consideration, as racial disparities have been reported in lower-extremity arthroplasty in the United States. Our study sought to examine these disparities.

Methods:

Using the National Inpatient Sample (NIS) database, all anatomic total shoulder arthroplasty (aTSA) and reverse total shoulder arthroplasty (RSA) procedures from 2011 to 2017 were analyzed. The patients were divided into the Black, Hispanic, and White groups.

Results:

Overall, 91.4% of the patients undergoing any shoulder arthroplasty procedure were White, 4.75% were Black, and 3.85% were Hispanic. Age and sex-standardized RSA utilization rates (per 100,000) in White patients increased by 139% from 6.94 in 2011 to 16.60 in 2017. The disparity for Black patients, compared with White patients, was 118% in 2011 and 124% in 2017; the disparity for Hispanic patients was 112% in 2011 and 103% in 2017. Similar disparities in aTSA utilization rates were seen; when compared with White patients, there was a 150% disparity in 2011 and a 197% disparity in 2017 for Black patients, and a 169% disparity in 2011 and a 262% disparity in 2017 for Hispanic patients. Finally, Blacks had a higher rate of non-home discharge, longer length of stay, and higher overall costs, while Hispanics had a longer length of stay and higher cost than Whites.

Conclusions:

Despite many efforts to reduce racial disparities in health-care utilization, the chasm in shoulder arthroplasty in the United States appears to be large and widening further. The exponential increase in utilization of shoulder arthroplasty has not been shared equally among races, and the disparities are larger than those reported in lower-extremity arthroplasty.

Registry-Based Randomized Controlled Trials: Conduct, Advantages and Challenges – A Systematic Review.
Authors: Shea Niamh O , Eustace Joseph , Murphy Ellen , Shiely Frances
Published: June 2022

Background: Registry-based Randomized Controlled Trials (rRCTs) have been described as pragmatic studies utilising patient data embedded in large scale registries, to facilitate key clinical trial procedures including recruitment, randomization and the collection of outcome data. While the practice of utilising registries to support the conduct of randomized trials is increasing, the use of the registries within rRCTs is inconsistent. The purpose of this systematic review is to explore the conduct of rRCTs using a patient registry to facilitate trial recruitment and the collection of outcome data and to discuss their advantages and challenges. Methods: A systematic search of the literature was conducted using five databases from inception to June 2020: PubMed, Embase (through Ovid), CINAHL, Scopus, and the Cochrane Controlled Register of Trials (CENTRAL). The search strategy comprised of MESH terms and key words related to rRCTs. Study selection was performed independently by two reviewers. A risk of bias for each study was completed. A narrative synthesis was conducted. Results: A total 47862 titles were screened and 24 rRCTs were included. Eleven rRCTs (45.8%) used more than one registry to facilitate trial conduct. Six rRCTs (25%) randomized participants via a specific randomization module embedded within a registry. Recruitment ranged between 209 to 106,000 participants. Advantages of rRCTs are recruitment efficiency, shorter trial times, cost effectiveness, outcome data completeness, smaller carbon footprint, less participant burden and ability to conduct multiple trials from the same registry. Challenges are: data collection/management, quality assurance issues and the timing of informed consent. Conclusion: Optimising the design of rRCTs is dependent on the capabilities of the registry. New registries should be designed, and existing registries reviewed to enable the conduct of rRCTs. At all times, data management and quality assurance of all registry data should be given key consideration. We suggest the inclusion of the term ‘registry-based’ in the title of all rRCT manuscripts and a clear simple breakdown of the registry-based conduct of the trial in the abstract, to facilitate indexing in the major databases.

Quantum and classical study of prime numbers, prime gaps and their dynamics
Authors: Pal Charli Chinmayee , Mahapatra Prasanta Kumar , Mishra Subodha
Published: June 2022

A wave function constructed from prime counting function is employed to study the properties of primes using quantum dynamics. The prime gaps are calculated from the expectation values of position of prime numbers. In an analogous nonlinear system, the trajectories, associated nodes with their stability condition and the bifurcation dynamics are studied using classical dynamics. It is interesting to note that the Lambert W functions appear in connection to solutions for the fixed points as functions of energy. The derived potential with the divergence also resembles the effective potential a test particle feels near a massive spherical object in General Theory of Relativity. The coordinate time and proper time corresponding to a black hole serendipitously find their analogy in the solution of the nonlinear dynamics representing primes. The stereographic projection obtained from quantum dynamics on unit circle in the (θ, p θ ) phase space of the real numbers present along x-axis in general and prime numbers in particular provides a simple way to calculate a formula for upper bounds on the prime gaps. The estimated prime gaps is found to be significantly better than that of Cramer’s produced values.
Rural Poverty and Energy Choice: New and Global Evidence
Authors: Falco Salvatore Di , Lynam Gary
Published: June 2022

We combined a global micro level dataset that includes 17 different rural Sub Saharan countries with satellite information about precipitation during the growing season to estimate the impact of economic conditions on energy choice. Differently from the existing literature, we aim to causally estimate the impact of household welfare variation on the likelihood of choosing a specific energy source. It is found that, consistent with theory, increases in income do determine an increase in likelihood of using relatively cleaner sources of fuel. We find, however, that this impact is quantitatively very small. Results hold conditional on assets, wealth and a large battery of controls and fixed effects. Policy implications are developed.
Novel ENG metamaterial for Gain enhancement of an off-set fed CPW Concentric circle shaped patch antenna
Authors: A Sujatha Priyadharshini , Arvind C. , Karthikeyan Madurakavi
Published: June 2022

This paper presents a multiband coplanar waveguide (CPW)-fed concentric circle shaped patch antenna for WLAN, LTE-A, 5G Wi-Fi, and X-band applications, which is loaded with metamaterial unit cell. The proposed patch antenna employs arc shaped patch and concentric circle shaped patch achieves ultra-wideband operation. The proposed two layer antenna configuration consists of metamaterial super-substrate. The measured reflection co-efficient (S11) demonstrated three wideband operation ranging from 3.06GHz − 4.72GHz (B.W of 42%), 4.94GHz-6.19GHz (B.W of 22%) and 6.50 GHz − 10.56 GHz (B.W of 47.5%). The metamaterial structure is obtained through the arrangement of the proposed unit cell in 5 × 5 order. The proposed metamaterial structure properties were examined for wave propagation through the material in two major axes directions (x and y-axis). For both axis, the metamaterial exhibits near Zero refractive index for wide range of frequency. The addition of this super-substrate provides significant gain enhancement by 181% when the maximum gain reaches 6.2 dBi at X-band frequency. Since the proposed antenna is more efficient, it might be used for X-band operations such as satellite communication, military, and medical monitoring.
WITHDRAWN: Outcome of Anterior Curciate Ligament Reconstruction with a Large-size Graft versus an Extraarticular Tenodesis; A Comparative study
Authors: El-Azab Hossam , Moursy Mohamed , Mohamed Mohamed Ali , Elsayed Moustafa
Published: June 2022

Introduction: Large number of patients after Anterior Cruciate Ligament (ACL) reconstruction (R) complain of instability, inability to return to the previous level of sports activity and develop ACL graft failure. There are two augmentations to ACL-R to increasec the stability of knee. Those augmentations either a large-size ACL-graft or combination with extraarticular tenodesis (LET). . Patients and Methods: A Prospective Randomized Comparative study included 100 consecutive patients, who underwent ACL-R with Hamstring Tendon Graft. The patients were allocated into two groups (Group A and B) with Randomization; group A received ACL-R with a large ACL-graft diameter (Triple graft) and group B received ACL-R with a double graft combined with lateral extraarticular tenodesis (Modified Lamaire). Each group had fifty patients. Follow-up was for 2 years. They were examined for graft failure, rotatory instability with the pivot shift test and the outcomes were measured with the international knee documentation committee‘s (IKDC) both subjective and objective scores. Results: In group A, graft failure occurred in two (4.1%) patients, the pivot shift test was positive in three (6.5%) patients, the subjective IKDC score was 90.94 points, and the objective IKDC score was normal or nearly normal in 43 (93.4%) patients. In group B, graft failure occurred in one (2.1%) patient, the pivot shift test was positive in one (2.1%) patient, the subjective IKDC score was 91.9 points, and the objective IKDC score was normal or nearly normal in 44 (95.6%) patients. Conclusion: Both large graft-diameter and combination with extra-articular tenodesis decrease ACL-graft failure rates, postoperative rotatory instability, and improve clinical outcome. However, the combination of anterior curciate ligament reconstruction with extra-articular tenodesis was more effective than large-sized grafts for curciate ligament reconstruction. Level of evidence: Level 1; Randomized Comparative study.
Developing a new hydrological drought index and comparing it with meteorological drought indices in Iran's various climates
Authors: Mosaedi Abolfazl , Sarparast Mehdi
Published: June 2022

Drought is a natural phenomenon that can have an impact on many aspects of human life. Drought indices are commonly used to monitor drought levels. In this research, a fundamental change was made on structure of the SPI index and the hydrological effective rainfall was replaced by total precipitation, thus the new hydrological drought index (SPIH) was derived. The SPIH index was used to present the hydrological drought status of Iran's climatic zones over a 63-year period (1955–2018). Furthermore, it was compared to the four other drought indices of SPI, SPEI, RDI, and RDIe in six stations chosen to represent each climatic zone of Iran (coastal wet, mountain, semi-mountain, semi-desert, desert, and coastal desert). In general, changes in the correlation coefficient between all drought indices demonstrate that with decreasing precipitation and rising evapotranspiration, the correlation coefficient declines and the disparity between all the indices becomes more evident. In most climatic zones, with the exception of coastal wet, the correlation between SPI-SPIH is not as strong as the two-way correlation between other indices. The coastal wet regions have the highest correlation between SPI and SPIH (0.98), followed by mountainous (0.93), semi-mountainous (0.92) regions, and desert areas have the lowest (0.61). In general, in arid areas, hydrological drought based on the SPIH index has a low association with meteorological drought based on the SPI, SPEI, RDI, and RDIe indexes. This demonstrates that there are differences between meteorological drought (SPI, SPEI, RDI, and RDIe) and hydrological drought indices (SPIH) in different climates.
A Hybrid Cryptography and End-to-end Security Model for Wireless Sensor Netwoks

Published: June 2022

Wireless Sensor Network (WSN) is an interconnected and infrastructure-less wireless network. It is deployed in many wireless sensors in an ad-hoc manner to monitor the system, physical or environmental conditions. Wireless sensor networks are used to develop the applications in healthcare, agriculture, vehicle network, defense, etc. Due to this network's need to provide proper security techniques to ensure secure communication. The hybrid cryptographic approach is suitable for WSN because it can take care of sensor's challenges like computation power, storage capability and energy. Symmetric-key cryptography is used to track only one key for the encryption and decryption process. So its computation speed is high. An asymmetric key is used to share information in a very secure way. Both can provide more security against attacks in wireless networks. A new two-phase cryptographic technique has been developed in this work that uses both symmetric and asymmetric methods. In the proposed algorithm, advanced encryption standards (AES) and Rivest–Shamir–Adleman (RSA) are used in different phases of the algorithm. Because symmetric key cryptographic techniques provide a high level of security, and asymmetric key cryptography provides easier key management. phase 1 has been developed using the AES algorithm. In phase 2, RSA has been used, and all phases are executed in parallel. The proposed algorithm provides better encryption, decryption and total execution time when compared to the existing algorithms.

Introduction
: Disaster planning is of significant importance for the healthcare professional and the healthcare setting. Hospital-based disaster protocols form the cornerstone of disaster response. There is a paucity of data on disaster preparedness training using the Virtual Tabletop exercise (VTTX) module for interprofessional education from in-hospital and prehospital settings. With the COVID-19 pandemic, we have seen a paradigm shift of education strategies to the virtual realm. Here we attempt to study the impact of an online tabletop exercise workshop on the knowledge and confidence of disaster preparedness among Interprofessional trainees.
Methods
Interprofessional trainees from medical, dental, nursing, respiratory therapy, and paramedic domains who consented were included in this study. Institutional ethics committee approval was received and the study was registered with the clinical trials registry India (CTRI), before initiation. The VTTX module has been adapted from the WHO COVID-19 training resources. Three international experts from the disaster medicine domain validated the module, questionnaire, and feedback. Wilcoxon signed-rank test was used to compare the parameters (Knowledge and confidence level) pre and post-workshop.
Results
A total of 76 candidates with a mean age was 21.67 ± 2.5 (Range:19–36) were part of the workshop. Comparison of the median scores and interquartile range of confidence level and knowledge respectively before [38 (29.25–45.75), 9 (7–11)] and after [51.50 (45–60), 11 (10–12)] the workshop showed vital significance (P-value < 0.001). All participants gave positive feedback on the workshop meeting the objectives. The majority agreed that the workshop improved their self-preparedness (90%) and felt that the online platform was appropriate (97.5%).
Conclusion
This study sheds light on the positive impact of the online VTTX workshop on disaster preparedness training among Interprofessional trainees. Disaster preparedness training using available online platforms may be effectively executed with a VTTX workshop even during the COVID-19 pandemic. The VICTEr workshop serves as a primer for developing online modules for effective pandemic preparedness training in interprofessional education.
