Frequency of De Quervain’s Tenosynovitis in Carpenters of Lahore
Authors: Saadat Maira
Published: April 2022

Background: De Quervain’s tenosynovitis is described as overuse tendon injury and characterized by painful movements of the fibro-osseous sheath of the extensor pollicis brevis and abductor pollicis longus tendons in which pain is aggravated by thumb movements and wrist movements during functional activities. Objective: To evaluate the frequency of de Quervain’s tenosynovitis in carpenters of Lahore. Methods: A survey was consisting of 103 patients conducted and selected by non-probability convenient sampling in six months; duration. Data collection was done by using the standard ‘Patient Rated Wrist/Hand Evaluation’ questionnaire after taking the informed written and verbal consent. The standard Finklestein test helped in diagnosing this condition. The participants who experienced pain at the wrist, over the extensor pollicis brevis and abductor pollicis longus tendons were considered positive for tenosynovitis. Frequency and percentages were calculated for categorical variables. Results: The results showed that the frequency of de Quervain’s tenosynovitis with positive Finklestein’s test was 50.45%, 25.2% for worst ever pain, 26.2% with repetitive wrist movements and 25.2% while doing work job in carpenters of Lahore. The Finklestein’s test was positive in 71 (69%) carpenters and 32 (31%) showed a negative test. The mean pain score for positive Finkelstein’s test was 6.93±20.40 and for negative F test was 5.24±15.91. The difference was statistically significant at p<0.001. Among carpenters, age and work duration were strongly correlated (r=0.807) and there is a moderate correlation between age and the total score (r=0.78). Conclusion: It was concluded that most carpenters have a moderate level of pain during repetitive wrist movements while working. While a majority of the carpenters have positive Finkelstein’s test. Significant results were found showing moderate pain levels with positive tests. A strong correlation was found between age and duration of work.

After the Arab Spring: Civil War and Failed Efforts of Reconciliation in Libya
Authors: Chaudhry Mahnoor
Published: April 2022

In this article, I will briefly mention the events that led to the uprisings of the Arab Spring. My major focus will be on the causes that led to the civil war against the regime of Muammar Gadaffi. I will mention all the major factors that contributed towards the civil war i.e the history of the regime, the international influences, the territoriality of the conflict, and the militarization of the two opposing forces. Then I will briefly describe the death event of Muammar Gaddafi. Once the objective of the revolutionists was obtained (the downfall of Gaddafi), the country fell apart. Instead of leading towards the state of democracy, the state was divided into much more opposing forces. Finally, I will discuss some causes that were the contributing causes towards the failure of the efforts of national reconciliation.
Surveillance and Panopticism in the Digital Age
Authors: Bashir Maryam
Published: April 2022

With the advancement in technology over the past few decades, there has been a rapid increase in state of the art surveillance tools and techniques. Surveillance is becoming a global issue in the digital age. The world is compelled to understand the dynamics of surveillance in the contemporary world. Surveillance has changed from being physical and spatial to being networked and it relies heavily on modern technology. So, it is indispensable to recognise the ever-changing forms of surveillance. The capacity of surveillance has dramatically increased with new digital technology. It has become an important issue in surveillance studies and we need to understand its intangible risks and complexities in the digital age. The revisitation of the ideas of Jeremy Bentham, Michel Foucault, Karl Marx as well as those of contemporary social theorists like David Lyon, Zygmunt Bauman, F�lix Guattari, Gilles Deleuze and others plays a vital role in the development and understanding of new theoretical approaches in surveillance studies. With the rise in surveillance tools and techniques there has also been a change in power dynamics in the society. So, surveillance studies not only provide a helping hand to understand the complexities of new and different forms of surveillance but also help to understand the changing power dynamics in the society. Living in a �Surveillance Society� has led to new, different and extreme forms of power and control. The misuse of surveillance technologies leads to exploitation of the masses, discloses their intimate lives as well as becomes a threat to privacy and freedom of expression and liberty. The world should be made conscious of the repercussions associated with surveillance in the digital world.

Surgeon’s guilt after postoperative complication
Authors: Bhattacharya Kaushik , Bhattacharya Neela
Published: April 2022

Surgery is an art, surgical dilemmas are not mathematical problems with rigid, straight cut solutions and the human mind/body is not a perfect science. In such a scenario, unexpected, sudden complications can happen during surgery. While better diagnostic and advanced techniques in surgery, have minimised surgical errors to a great extent, with the risk of post-operative death being as low as 3.6% now, still when complications due occur, the surgeon faces a huge backlash not only from the patient relatives, but from his peers, the hospital management, the social and print media. The surgeon also fears violent retribution, not just consumer issues but a threat of arrest and legal battles. All these make a surgeon the “second victim” in the event of a post-operative complication, leading to changes in practice behaviour, emotional turmoil and even serious mental issues like depression and suicide. In this era of instant judgement by a largely unregulated social media, it is urgently required to address this issue and provide appropriate strength/support to the surgical fraternity.

Maximizing COVID-19 Vaccine Acceptance in Developing Countries
Authors: Tunde Gbonjubola Yusuff , Garba Muhammad Daha , Chisom Anastasia Nwaezuoke , Elisha Adekolurejo Tobi
Published: April 2022

Coronavirus disease 2019 (COVID-19) is still in existence, with the capacity to spread even further. Vaccination could efficiently reduce the burden of the pandemic, but first, people must accept these vaccines. Vaccine acceptance by the population is crucial to control the pandemic and prevent further deaths. Herd Immunity, which is the indirect protection that occurs when a sufficient percentage of a population has become immune to an infection, offers some protection to unvaccinated individuals. However, herd immunity is compromised when widespread vaccine acceptance is not achieved. Some vaccines have been authorized to prevent COVID-19, such as Pfizer-BioNTech, Moderna, Johnson & Johnson\'s Janssen, and Oxford-AstraZeneca COVID-19 Vaccine. While vaccine development has been achieved within a short time, its safety, potency, efficacy, and universal accessibility are of great concern and could influence vaccine acceptance. Conspiracy beliefs rampant in Africa may influence vaccine hesitance; exposure to anti-vaccine theories decreases willingness to accept vaccination. As such, there is a need for the availability of reliable information about vaccines, messages that highlight the vaccines efficacy and safety could be effective for addressing the hesitancy to increase the acceptance level of the COVID-19 Vaccine in Africa.
Differential Undercounts in the U.S. Census: Who is Missed?
Authors: Solis Eimmy
Published: April 2022

As the topic of social injustice becomes more prominent in academic and community discussions, the general public and researchers may be interested in learning about the relationship between data accuracy in census surveys and social inequality in the United States. This book is a compilation of statistics and data discussing why certain groups of people have historically been uncounted and omitted in the decennial census. The decennial census is a count conducted every ten years of every person living in the United States in order to allocate federal funding to states for social services, determine state and congressional legislative districts, and the number of US House of Representatives for each state. William O’Hare gathers available information regarding undercounts and omission rates in the decennial census and summarizes the data to make it understandable for a general audience, as often this data is buried within census reports and presentations. In addition, O’Hare provides references to the data and methodology.

Factors affecting the adaptation of olive oil organizations to covid-19
Authors: Mozas Moral Adoración , Fernández Uclés Domingo
Published: April 2022

The covid-19 pandemic has had catastrophic effects on the global economy. The olive oil sector, whose producers were already undergoing their own crisis, has also clearly been affected by this situation. Despite Spain’s world leadership in olive oil production, the added value that this product can generate has not been maximized. Falling prices and supply saturation are the problems that have been most highlighted and to which covid-19 has added. Faced with such a situation, the digitalization of the olive mill has gone from being a recommendation to an essential factor in avoiding the paralysis of its activity. In this context, the objective of this study is to detect the organizational factors that have been associated with a better adaptation of the organizations to the current complex situation. To this end we have made use of the fuzzy sets Qualitative Comparative Analysis technique which makes it possible to contrast different variables in order to explain a result, overcoming the limitations of more traditional techniques. The results obtained reveal that the cooperative form, the degree of innovation, the training of the top managers and the flexibility and size of the organization are factors that contribute to a better adaptation of the olive mill to the situation caused by covid-19.
The stage of initiation of a criminal case as an administrative barrier, beyond which a preliminary investigation begins (for example, Article 177 of the Criminal Code of the Russian Federation and other elements of crimes under the jurisdiction of the FSSP of the Russian Federation).
Authors: Sasykin Konstantin Yurievich
Published: April 2022

The article is devoted to the assessment of the actual possibility of citizens' realization of the constitutional right to access to justice in the conditions of the current model of criminal proceedings in the Russian Federation. The author investigates the problems of the application of certain provisions of the criminal procedure legislation of the Russian Federation defining the reasons, grounds and timing of the initiation of a criminal case, combined into the stage of initiation of a criminal case (Chapters 19-20 of the Code of Criminal Procedure of the Russian Federation). The question of the need to reform domestic legislation in this part in order to increase the effectiveness of the criminal procedural function of the state is being investigated. The study is based on the perspective of topical issues of initiating criminal cases for crimes under the jurisdiction of the FSSP of the Russian Federation, including those provided for in Article 177 of the Criminal Code of the Russian Federation, taking into account official statistics for 2020 and judicial practice on citizens' complaints. The relevance is based on disappointing data on the execution of judicial acts in the Russian Federation. In particular, attention is drawn to the presence in 2020 of more than 110.5 million enforcement proceedings in the FSSP of the Russian Federation, the generalized level of enforcement for which amounted to no more than 50%, totaling 696 billion rubles, which is a serious threat to economic stability and requires timely response. The relevant data are considered as a consequence of the existing barrier at the stage of initiation of criminal proceedings in the implementation of criminal legislation, including determining responsibility for crimes against the authorities, malicious non-execution of judicial acts, which is also confirmed by unjustified indicators of the initiation of criminal cases under Articles 177, 311, 312, 315 of the Criminal Code of the Russian Federation. In order to ensure the implementation of the criminal procedural function of the state, a comprehensive reform of this stage is proposed by transforming it into the institution of the beginning of criminal proceedings, which will restore the preventive function of the norms of the criminal legislation of the Russian Federation and ensure the effective operation of state authorities.

The subject of the study of the topic under consideration is the implementation of the powers of the internal affairs bodies in ensuring public safety at air transport facilities. The article shows the role of the internal affairs bodies in ensuring public safety through the implementation of the powers assigned to them. The article is a structural presentation of the material on the implementation of law enforcement tasks at air transport facilities. The introduction describes the relevance of the field of aviation transport to meet the needs of society, the high demand of the population for this type of transport, the tasks of law enforcement agencies and air transport enterprises to ensure the safety of citizens while they are at the airport and during the flight. The main part explains the issues related to the use of regulations as a means of preventing persons from entering air transport facilities when performing work related to transport security by checking them against various databases, the results of which are concluded. An idea is given about the use of the norms of legislation providing for liability in the case of an administrative offense or crime. The article may be useful to those who are involved in the process of ensuring security at air transport facilities, law enforcement officers, subjects of ensuring transport security – employees of the aviation security service and departmental security of the Ministry of Transport of the Russian Federation, as well as whose interests are related to carrying out work at such facilities, and citizens using air transport services. Thus, the concentration of efforts in the field of public safety, based on the application and implementation of legal norms by the subjects involved in this process, understanding the importance of aspects of interaction in the implementation of the powers granted, as well as the overall organization of activities at air transport facilities will allow us to talk about the effectiveness of the entire security system focused mainly on the social needs of citizens and interests states.

Published: April 2022

The subject of the study is the organizational and legal problems of the functioning of public councils under the Ministry of Internal Affairs of Russia and its territorial bodies in matters of road safety. The object of the study is public relations related to the functioning of public councils under the Ministry of Internal Affairs of Russia and its territorial bodies. As a result of the analysis of normative legal acts, scientific literature, the author comes to the conclusion that despite the existence of public councils for more than ten years, the analysis of the practice of their functioning allows us to assert that there are separate problems, both legal and organizational, that do not allow them to fully fulfill their intended purpose expressed in the coordination of the coordination of socially significant interests, solutions to the most important issues of the activities of internal affairs bodies, including in the field of road safety. The methodological basis of the research was a complex of general scientific and private scientific methods of cognition (formal legal, analytical, system analysis, synthesis, modeling, comparison, etc.), special scientific (technical and legal analysis, etc.). The scientific novelty of the research is expressed in the author's vision of the solution of the identified problems of the functioning of public councils. The author's general conclusion is the statement that the high social significance of the road traffic sphere for society determines the need to improve the mechanisms of citizens' participation in the management of public relations related to ensuring the safety in question, one of which is the public councils under the federal executive authority in the field of internal affairs and its territorial bodies. For the effective functioning of the institution under consideration, it is necessary to improve the organizational and legal foundations that help transform it into a real tool for expressing the position of civil society, allowing for managerial influence on the sphere of traffic.

Geocultural branding as a tool for solving the crisis state of the socio-economic sphere of a rural settlement
Authors: Dianov Sergei Aleksandrovich , Poluyanova Olga Georgievna , Chegodaev Viktor Petrovich
Published: April 2022

In this article, geocultural branding of territories is considered in the context of the theory of political management, which can be used in solving the problems of the socio-economic sphere of rural settlement. In the scientific literature, insufficient attention is paid to the branding of Russian rural settlements. Individual stories can be found only in the publications of specialists in the field of marketing territories. According to the author's point of view, a progressive solution that allows creating conditions for sustainable socio-economic development in a rural settlement is the development and implementation of a geocultural branding strategy for the settlement. On the example of the village of Bard, a large rural settlement of the Perm Region, measures for the development of a geocultural strategy and brand are proposed. Among the image resources of the village, unique natural places, craft traditions, national ornaments, mythologems of the Tulva district, as well as art objects as an organic part of the public spaces of the settlement are singled out separately. The historical personality of the Tatar poet Gabdulla Tukai (the beginning of the XX century) is proposed as the "genius of the place". The geocultural brand "Barda ‒ mirror of the Perm land" was developed based on the poetic creativity of G. Tukai. Barda can really be considered a mirror of the Permian land. Good-neighborly relations between ethnic communities have historically developed here, religious tolerance has taken place in everyday life, traditional types of economy and life have developed. The concept of geocultural branding of territories was used as a methodological basis (D.N. Zamyatin).
French mystery drama in the mirror of the twentieth century
Authors: Azarova Valentina Vladimirovna
Published: April 2022

The article considers the reflection of the basic laws of the mystery of the XIV–XVI centuries in the musical and theatrical works of the French "synthetic theater" of the twentieth century. These are "The Martyrdom of Saint Sebastian" by G. d'Annunzio — C. Debussy (1911) and "The Good News of Mary" by P. Claudel (1912-1948). The purpose of the work is to establish the peculiarities of the operation of the principles of semantics and composition of the genre, revived at the end of the XIX century and further developed in the French musical theater. In interdisciplinary, hermeneutical and art criticism approaches to achieving this goal, we distinguish a comparative method that allows us to draw conclusions about the identity and difference of the elements of these works, as well as about the genre "codes" of mystery dramas that enter into dialogue over a significant (about 300 years) time interval. We are talking about a dialogue within the history of Western European theater. In favor of the scientific novelty and significance of the work, we present theses on the integration of the spiritual dimension into the space of the mystery drama of the twentieth century, as well as on the relevance of the spiritual messages of the French composers of the twentieth century, who created mystery dramas in line with the Christian tradition. Conclusions are drawn: About the functions of liturgical choirs in Latin in French mystery dramas of the twentieth century, revealing the spiritual meaning of the works considered in this article. On the interaction of the sacred and profane as the leading genre feature of the mystery drama of the XIV–XVI centuries and the twentieth century. About the preservation of the spatial vector "earth — sky" by the French mystery drama of the twentieth century. On the connection of the French mystery drama of the twentieth century with the spiritual problems of modernity. About the search by the French mystery drama of the twentieth century for the possibility of overcoming the discrepancies between the world, God and man. About the inclusion of the French mystery drama of the twentieth century in the general cultural context.
Quasi-parity-time symmetric dynamics in periodically driven two-level non-Hermitian system
Authors: Hu Zhou , Zeng Zhao-Yun , Tang Jia , Luo Xiao-Bing ,   Department of Physics, Zhejiang Sci-Tech University, Hangzhou 310018, China,   School of Mathematics and Physics, Jinggangshan University, Ji’an 343009, China
Published: April 2022

In recent years, there have been intensive studies of non-Hermitian physics and parity–time (PT) symmetry due to their fundamental importance in theory and outstanding applications. A distinctive character in PT-symmetric system is phase transition (spontaneous PT-symmetry breaking), i.e. an all-real energy spectrum changes into an all-complex one when the non-Hermitian parameter exceeds a certain threshold. However, the conditions for PT-symmetric system with real energy spectrum to occur are rather restrictive. The generalization of PT-symmetric potentials to wider classes of non-PT-symmetric complex potentials with all-real energy spectra is a currently important endeavor. A simple PT-symmetric two-level Floquet quantum system is now being actively explored, because it holds potential for the realization of non-unitary single-qubit quantum gate. However, studies of the evolution dynamics of non-PT-symmetric two-level non-Hermitian Floquet quantum system are still relatively rare.

In this paper, we investigate the non-Hermitian physics of a periodically driven non-PT-symmetric two-level quantum system. By phase-space analysis, we find that there exist so-called pseudo fixed points in phase space representing the Floquet solutions with fixed population difference and a time-dependent relative phase between the two levels. According to these pseudo fixed points, we analytically construct a non-unitary evolution operator and then explore the dynamic behaviors of the non-PT-symmetric two-level quantum system in different parameter regions. We confirm both analytically and numerically that the two-level non-Hermitian Floquet quantum system, although it is non-parity-time-symmetric, still features a phase transition with the quasienergy spectrum changing from all-real to all-complex energy spectrum, just like the PT symmetric system. Furthermore, we reveal that a novel phenomenon called quasi-PT symmetric dynamics occurs in the time evolution process. The quasi-PT symmetric dynamics is so named in our paper, in the sense that the time-evolution of population probabilities in the non-PT-symmetric two-level system satisfies fully the time-space symmetry (PT symmetry), while time-evolution of the quantum state (containing the phase) does not meet such a PT symmetry, due to the fact that time-evolution of the phases of the probability amplitudes on the two levels violates the requirement for the PT symmetry.

Published: April 2022

In 2016, Madera et al. tested the performance of a fuzzy inference system against the Google Ads algorithms for optimizing the number of clicks, the click through rate (CTR) and the average cost per clicks to lower the cost of an advertising campaign [7]. The results of their experiments suggested that the implementation of their fuzzy inference system outperformed the Google Ads algorithms in terms of the obtained number of clicks and cost per clicks. While the research idea is with no doubts an interesting and valuable contribution to the fields of digital marketing research, in the opinion of the authors, their experimental setup was flawed. However, applying a few adjustments can lead to valid findings. This paper reflects on the flaws and suggests enhancements to correct them.
Multi-omic rejuvenation of human cells by maturation phase transient reprogramming

Published: April 2022

Ageing is the gradual decline in organismal fitness that occurs over time leading to tissue dysfunction and disease. At the cellular level, ageing is associated with reduced function, altered gene expression and a perturbed epigenome. Recent work has demonstrated that the epigenome is already rejuvenated by the maturation phase of somatic cell reprogramming, which suggests full reprogramming is not required to reverse ageing of somatic cells. Here we have developed the first “maturation phase transient reprogramming” (MPTR) method, where reprogramming factors are selectively expressed until this rejuvenation point then withdrawn. Applying MPTR to dermal fibroblasts from middle-aged donors, we found that cells temporarily lose and then reacquire their fibroblast identity, possibly as a result of epigenetic memory at enhancers and/or persistent expression of some fibroblast genes. Excitingly, our method substantially rejuvenated multiple cellular attributes including the transcriptome, which was rejuvenated by around 30 years as measured by a novel transcriptome clock. The epigenome was rejuvenated to a similar extent, including H3K9me3 levels and the DNA methylation ageing clock. The magnitude of rejuvenation instigated by MPTR appears substantially greater than that achieved in previous transient reprogramming protocols. In addition, MPTR fibroblasts produced youthful levels of collagen proteins, and showed partial functional rejuvenation of their migration speed. Finally, our work suggests that optimal time windows exist for rejuvenating the transcriptome and the epigenome. Overall, we demonstrate that it is possible to separate rejuvenation from complete pluripotency reprogramming, which should facilitate the discovery of novel anti-ageing genes and therapies.
Learning cortical representations through perturbed and adversarial dreaming
Authors: Deperrois Nicolas , Petrovici Mihai A , Senn Walter , Jordan Jakob
Published: April 2022

Humans and other animals learn to extract general concepts from sensory experience without extensive teaching. This ability is thought to be facilitated by offline states like sleep where previous experiences are systemically replayed. However, the characteristic creative nature of dreams suggests that learning semantic representations may go beyond merely replaying previous experiences. We support this hypothesis by implementing a cortical architecture inspired by generative adversarial networks (GANs). Learning in our model is organized across three different global brain states mimicking wakefulness, non-rapid eye movement (NREM), and REM sleep, optimizing different, but complementary, objective functions. We train the model on standard datasets of natural images and evaluate the quality of the learned representations. Our results suggest that generating new, virtual sensory inputs via adversarial dreaming during REM sleep is essential for extracting semantic concepts, while replaying episodic memories via perturbed dreaming during NREM sleep improves the robustness of latent representations. The model provides a new computational perspective on sleep states, memory replay, and dreams, and suggests a cortical implementation of GANs.

Background

The fishery processing industry produces a remarkable number of by-products daily. Fish skin accounts for one of the significant wastes produced. Fish skin, however, can be subjected to extraction to yield gelatine and used as the primary raw material for edible film production. To increase the functionality of edible films, bioactive compounds can be incorporated into packaging. Mangroves produce potential bioactive compounds that are suitable as additional agents for active packaging. This study aimed to create a fish gelatine-based edible film enriched with mangrove extracts and to observe its mechanical and biological properties.

Methods

Two mangrove species (Bruguiera gymnorhiza and Sonneratia alba) with four extract concentrations (control, 0.05%, 0.15%, 0.25%, and 0.35%) were used to enrich edible films. The elongation, water vapour transmission, thickness, tensile strength, moisture content, antioxidant and antibacterial properties of the resulting packaging were analysed.

Results

The results showed that the mangrove species and extract concentration significantly affected (p < 0.05) the physical properties of the treated films such as elongation (16.89–19.38%), water vapour transmission (13.31–13.59 g/m2), and active packaging-antioxidant activities (12.36%–60.98%). The thickness, tensile strength, and water content were not significantly affected. Potent antioxidant activity and relatively weak antimicrobial activity of this active gelatine packaging were observed.

A rare subset of Coronavirus Disease-2019 (COVID-19) positive patients has musculoskeletal manifestations including arthritis, arthralgia, myalgia and non specific body aches. Moreover, postviral Reactive Arthritis (ReA) has been reported following COVID-19 infection. This article reports the characteristic joint manifestations of Severe Acute Respiratory Syndrome-Corona Virus-2 (SARSCoV-2) infection in 6 out of 211 consecutive patients with laboratory-confirmed diagnosis of COVID-19 and treated at dedicated hospital. One 49-year-old female patient developed arthritis while having active COVID-19 infection, one 54-year-old male had post-COVID-19 ReA, and one 48-year-old female was found to have undifferentiated arthritis. One 58-year-old female patient was initially thought to have ReA the diagnosis was reconsidered later when her symptoms resolved without any disease modifying agents. Two patients 37-year-old male and 63-year-old female, developed arthralgia following COVID-19 infection. Non Steroidal Anti-Inflammatory Drugs (NSAIDs) and steroids were found to be beneficial in the series of patients. The key point to be noted is that not all arthritis or arthralgia following COVID-19 is ReA.

Introduction: Until sufficient herd immunity is generated in the population, contact tracing, testing, and quarantining should be continued as key interventions in breaking the chain of transmission of Coronavirus Disease 2019 (COVID-19). Aim: To identify appropriate strategies for testing of the travellers, who were coming from high-risk areas by analysing patterns of testing among COVID-19 positive returnees. Materials and Methods: A retrospective cohort study was conducted in Community Medicine Department, Government Medical College, Palakkad, Kerala, India, during 25th Sepetember 2020 to 15th October 2020, using the secondary data available from the database of COVID-19 Contact Tracing Cell (CCTC) to determine the testing pattern among the laboratory confirmed cases of COVID-19 positive returnees in Palakkad district. Only COVID-19 positive travellers returning to Palakkad district in May 2020 were included in the study, thus the sample size obtained was 122. Data regarding age, gender, co-morbidity, presence of symptom and time of its onset, time of swab collection and reporting of results which were collected by CCTC were analysed. The Statistical Package for the Social Sciences (SPSS) version 20.0 was used to analyse the data collected by CCTC. Quantitative variables were summarised as means with standard deviations and median with interquartile ranges. Qualitative variables were summarised as percentages. Results: Between arrival and swab collection there was mean duration of 6.9±3.8 days and a median duration of 7 days among the total positive returnees. Among the asymptomatic cases the mean duration was found to be 7.4±3.6 days for the same. Between day 10 and day 12 of quarantine 79%- 91% of the cases have given swabs for Reverse Transcription Polymerase Chain Reaction (RT-PCR) testing. This had yielded 90% positive reporting within 14 days of quarantining. Total 10 cases were diagnosed after 14 days of quarantine due to late swab collection while in quarantine. Mean duration between symptom onset and swab collection among 22 symptomatic cases was 1.9±1.6 days (median= 2 days). Conclusion: Testing of asymptomatic returnees from high risk area may be initiated (swab collection) by day 10 as swabs collected around 10th day of quarantine capture maximum number of positive cases. A delayed initiation for testing may prolong the time taken for diagnosis. Those who have tested negative during 14 days of quarantine should self-monitor for symptoms and reduce contact with high risk persons for one more week.

The study was conducted on a sample of 70 deaf children, chronologically aged from 10 to 18 years. Letters of deaf respondents on topics of their choice were used as a measurement instrument. The goals of the research are: To examine the homogeneity of variance of content understanding of written form of expression based on measurements of applied language constructions and content within language discourse, and to determine the statistical significance of content understanding of written form of expression using language constructions within language discourse. The second goal of the study was to examine the connection of language constructions in the applied measurement space of the number of used written expressions in the content understanding of written communication, and to determine the statistical significance of the connection of language constructions in the number of used written expressions in content understanding of written communication. The results of the research showed that the deaf population is characteristic and homogeneous in the way, style of writing and content understanding of the written text observed through linguistic discourse in written dialogue. In the written form of exchange of communication content, a significant degree of communication competence has been achieved, or the comprehensibility of the written form of expression in terms of content understanding. Deaf persons achieve very modest linguistic competence. The reduced ability of deaf children to achieve linguistic competence is reflected through the simplicity of statements in the substantive sense of preferring statements, as one of the characteristics of the linguistic competence of the deaf population.
