Kriteria Prioritas Pemilihan Teknologi Pengolahan Limbah Cair Industri Tempe
Authors: Permatasari Cahyaning Kilang
Published: November 2021

The location of tempe processing adjacent to the settlement causes

problems. The resulting liquid waste makes people uncomfortable. This

is presumably because the liquid waste has not been managed properly,

because it is only dumped into the drainage channel. The majority of

tempe industrial entrepreneurs are home industries who are not aware of creating a healthy environment by paying attention to liquid waste

processing. There are many studies on technology for the tempe

industrial wastewater problem, but each technology has advantages and

disadvantages. It is necessary to have a system to choose the technology

that suits the waste conditions. This research takes a case study in

Karanganyar Regency. The Analytical Hierarchy Process (AHP) method

is a method of determining priority scale that can accommodate all

aspects. Furthermore, a sequence of criteria can be arranged as needed.

The results of the analysis with AHP are: technology criteria 31.09%;

environment 28.65%; economic 21.74% and social 18.53%.

Environmental sub-criteria showed the results of the removal of

ammonia 40.56%; treated water quality 30.74%; the amount of mud is

18.91% and the emission level is 9.80%. Technology sub-criteria are

ease of operation 28.67%; land area requirement 28.56%; service life of

28.05% and the potential of technology in the midification of 14.72%.

Economic sub-criteria with the results of operating costs 34.21%;

installation cost 33.28%; maintenance costs 23.78% and HR costs

8.73%. Social sub-criteria with the results of the need for employment of 49.10%; readiness of human resources 19.33%; implementation of

construction 16.74% and aesthetics 14.82%. The results of the AHP can

be used as input for tempe entrepreneurs, the government and the

community to improve the environmental quality of the tempe industrial wastewater. It is hoped that entrepreneurs will find it easier to determine the appropriate technology to treat the tempe industrial liquid waste.

A considerar que a inovação é o caminho para que ocorra o desenvolvimento econômico de uma nação e que o crédito rural é um instrumento para impulsionar a produção local, contemplando em suas linhas a aquisição de máquinas e equipamentos – uma das modalidades de inovação, este estudo tem como objetivo identificar a dinâmica do crédito rural para a inovação do setor primário no estado do Amazonas. Trata-se de uma pesquisa comparativa e quantitativa para a qual se utilizou a base de dados do Banco Central do Brasil (Bacen) – Matriz Quantidade e Valor dos Contratos de Investimento por Município. Adotou-se o Índice Normalizado de Crédito Rural (INCR) de Toledo Neto e Couto Junior (2011), o qual permitiu caracterizar a especialização da conta Investimento (se agrícola ou pecuária). O resultado aponta para uma expansão expressiva de recursos destinados à atividade agrícola no período de 2002 a 2018, sendo intensifi cada após o período da crise de 2008, além de uma mudança no padrão de especialização do crédito rural do estado do Amazonas, indo de medianamente especialista em crédito agrícola para especialista em crédito pecuário. Junto a isso observou-se um aumento na aquisição de máquinas, equipamentos, materiais e utensílios agrícolas, bem como a atividade de melhoramento das explorações agrícolas e pecuárias, caracterizando atividades inovativas nos dois setores. O resultado do estudo contribui para a divulgação da aplicação do crédito rural no estado do Amazonas, em especial para inovação de processo.

Cet article décrit l’organisation mise en place pour faire face à la crise sanitaire de 2020 au sein
de Veolia Eau d’Île-de-France (Vedif), qui gère le service public de l’eau potable pour le Syndicat des eaux d’Îlede-
France (Sedif). Le 31 décembre 2019, l’Organisation mondiale de la santé (OMS) est informée de cas de
pneumonies dans la ville de Wuhan en Chine. Avec l’apparition de cas en Europe et l’intensification de
l’épidémie Covid-19, la direction de Vedif considérant le risque comme réel et substantiel, constitue une équipe
pluridisciplinaire référente le 28 février 2020. La circulation du virus s’accentuant, le 6 mars 2020, le plan de
continuité d’activité Pandémie est activé. La cellule de crise mise en place a pour objectif premier la continuité
du service de l’eau et l’identification des activités essentielles. Des dispositions sont prises pour adapter
l’organisation et les conditions de travail face aux contraintes sanitaires. Un dialogue continu, par des réunions
régulières, s’instaure au sein de l’entreprise avec les salariés et les instances représentatives du personnel
(IRP). Pendant les périodes de confinement, le recours au télétravail généralisé, pour les activités le
permettant, est un atout majeur face à cette crise. Cette mesure est accompagnée d’un renforcement des
infrastructures et des protocoles de sécurité informatiques vis-à-vis du risque cyber. Le maintien opérationnel
des installations impose notamment un suivi renforcé des stocks de produits chimiques nécessaires
au traitement de l’eau ainsi qu’une surveillance et une maintenance accrues des équipements stratégiques.
Cette organisation permet de garantir le maintien du service de l’eau à 4,6 millions de consommateurs sur
150 communes, de répondre aux obligations gouvernementales et contractuelles, et de garantir la santé et la
sécurité des 1 400 collaborateurs assurant le service de l’eau quotidiennement. À l’issue de cette crise, un
retour d’expérience, avec une consultation élargie des salariés, permet de dégager des axes d’amélioration.

Les épidémies nécessitent un suivi d’indicateurs fiables et pertinents, afin d’éclairer les prises de décisions
sanitaires. Durant la pandémie de SARS-CoV-2, le suivi de la dynamique virale au sein de la population par
les approches individu-centrées s’est révélé complexe et fortement influencé par les porteurs asymptomatiques et
les modifications de la politique de dépistage. Dans ce contexte, d’autres indicateurs de suivi épidémiologique global
ont été très rapidement proposés. La quantification du virus dans les eaux usées, via des outils de biologie moléculaire,
s’est très vite révélée comme un indicateur de suivi de l’épidémie de Covid-19 novateur et objectif. Cette
« épidé miologie par les eaux usées » (WWBE pour wastewater-based epidemiology en anglais) dont la pertinence
avait été démontrée quelques années auparavant, est à présent un outil complémentaire de suivi épidémiologique.
Cet indicateur est recommandé par l’Union européenne depuis mars 2021. Le consortium Obépine, regroupant des
équipes de recherche interdisciplinaires a, dès le début de l’épidémie, travaillé sur cette thématique afin d’approfondir
et de maîtriser cet outil. Ce consortium de recherche est également à la base du réseau de surveillance national
français de l’épidémie via les eaux usées. Les méthodes de mesures, encore en cours d’optimisation dans les labo -
ratoires de recherche, nécessitent néanmoins de grandes précautions dans leur mise en oeuvre et leur interprétation
pour un usage de routine. À travers l’exemple du programme de recherche et du réseau construit par Obépine, nous
aborderons ici les différentes étapes nécessaires à la constitution de ce suivi épidémiologique via les eaux usées.
Différentes étapes nécessaires à sa maîtrise sont présentées ici ainsi que les premiers enseignements à retenir.

Published: November 2021

Farmer organizations are effective mechanisms for increasing agricultural production, darners income and reducing poverty. Regrettably, farmers have not taken advantage of the lofty benefits accruable to those who voluntarily join these organizations. The study estimated the factors influencing households decision to participate in cooperative organizations and also tested the level of agreement among identified constraints linked with participation. Multistage sampling procedure was employed to select 120 farmers for the study. Primary data  were obtained using questionnaires. Data were analyzed using Probit model and Kendall’s coefficient of concordance. Results of analyses revealed that the mean age, years of educational attainment  household size and years of farming experience were 32, 15, 5 and 7 respectively. Result of probit analysis further indicate that age of the farmer, farm income, household size, participation in meeting, major decision maker, distance of farm to the nearest road and farmers social status were the most critical factors influencing households decision to participate in cooperative organizations. Result of Kendall’s coefficient of concordance revealed that there was 0.42 (moderate agreement) between the ranking of constraints associated with farmers' participation in cooperative organizations. Furthermore, findings showed that the top five factors limiting households’ decision to participate in cooperative organizations were inadequate capital accumulation, high embezzlement of funds, poor leadership, recurring internal crises and lack of initiative. Policies to provide good and accessible roads, increase farmers incomes and encourage youths are rational options that will enhance effective participation in cooperative organizations.

THESAURUS MODELLING OF ENGLISH TERMINOLOGY OF SPORT (SEMANTIC FIELD “FOOTBALL”)
Authors: Жучкова Ирина Игоревна
Published: November 2021

Обнаружено, что в спортивном дискурсе англоязычных стран существуют специализированные понятия, которые не совпадают полностью по значению с русскими терминами. Это приводит к сложностям, которые препятствуют пониманию и правильному использованию спортивной терминологии. Цель проводимого исследования заключается в систематизации англоязычной футбольной терминологии с помощью тезаурусного подхода, предполагающего конструирование семантических полей и выявление информационно-семиотической природы изучаемой терминологии. В первой части работы подробно описывается методика конструирования тезауруса английской спортивной терминологии и обосновывается выбор информационно-семиотического подхода в качестве основы исследования. Во второй части исследования конструируется семантическое поле «Football» с наглядной схемой семантических отношений. Исследование показало, что в футбольном дискурсе не существует изолированных понятий, все исследуемые термины связаны друг с другом сетью иерархических, синонимических, вариативных и ассоциативных отношений. Более того, выявление информационно-семиотической природы английской футбольной терминологии не только способствовало разграничению нюансов в значении спортивных терминов, но и позволило наглядно проиллюстрировать связь терминов внутри поля посредством построения схем. Полученные результаты могут быть использованы в процессе профессиональной подготовки специалистов-лингвистов, учителей физической культуры, а также спортсменов, изучающих английский язык.

Within the English discourse of sport there are many special concepts that do not coincide in meaning with Russian terms. As a result, Russian people learning the English language do not understand the meaning of English sports terms and are confused in their use. The current research is aimed at systematizing English discourse of sport, and namely its football terminology, and revealing the semiotic structure of terms within it via thesaurus modelling of terms related to this discourse. In the first part of the work there is a description of the way the English thesaurus of sports terms was constructed. In addition, the author explains why the semiotic theory was chosen as the basis for this research. In the second part of the work the author presented a semantic field for the term football with a visual scheme of semantic relations. The research showed that there are no isolated terms in football discourse and all terms are connected with each other through hierarchic, synonymic, variance and associative relations. Moreover, systematizing terms via the thesaurus approach could help not only differenciate the nuances in meaning of sports terms but also illustrate the relations among these terms due to the constructed schemes. The achieved results can be used for the vocational training of students majoring in linguistics, sports, and Physical Education teachers.

Данная статья посвящена актуальной проблеме - диагностике уровня цифровой педагогической компетенции магистрантов социокультурного направления. Обеспечение усвоения магистрантами цифровых педагогических компетенций является необходимым для их дальнейшей успешной деятельности, ведь для магистерской ступени образования характерно получение более углубленных знаний, включающих организацию учебного процесса и управления им с помощью цифровых средств, создание и использование цифровых ресурсов, владение нормативно-правовой базой использования цифровых средств и т. д. Диагностика уровня цифровой педагогической компетенции дает представление о профессиональной подготовке обучающегося и позволяет в случае необходимости, оперативно скорректировать процесс обучения. Тем не менее, на данный момент в научной литературе не представлено единой методики диагностики цифровой педагогической компетенции.

This article is devoted to the acute problem of diagnosis of the level of digital pedagogical competence of socio-cultural master’s degree students. Ensuring the assimilation of digital pedagogical competencies by master’s degree students is necessary for their further successful activity, because the master's degree education is characterized by obtaining more in-depth knowledge that affects the organization of the educational process and its management using digital means, creation and use of digital resources, knowledge of the regulatory framework for the use of digital means, and so on. Diagnostics of the level of digital pedagogical competence gives an idea of the professional training of the student and allows, if necessary, to quickly adjust the learning process. However, at the moment, the scientific literature does not present a single methodology for diagnosing digital pedagogical competence.

Authors: Jubair Kazi , Islam Md Shariful , Chakraborty Dipto
Published: November 2021

Banana stems are very cheap and abundant in nature which can be used to extract fiber. In this paper, banana fiber is used as a reinforcement and epoxy as a matrix to manufacture banana fiber-reinforced epoxy composite. Glass fiber mat, and roving are also used as reinforcement along with banana fiber to manufacture hybrid composites. The objective of this paper is to compare the mechanical properties of hybrid composites with that of pure banana fiber-reinforced composites. The hand lay-up method is used to manufacture all the composites, and tensile and flexural properties are investigated according to the corresponding ASTM standard. It is found that the tensile and flexural strength of banana and glass fiber roving hybrid composites are much higher compared to pure banana fiber-reinforced epoxy composites which make this hybrid composite suitable for low strength application.

There is a set of unresolved issues at the point where interests of land owners, land users and the government clash, that witnesses the absence of effective mechanisms of the formed land tenure system improvement. At the transition to the market relations, with the private land property environment, new effective approaches to land redistribution and rational land use support are necessary. The research objective is the development of a complex approach to the land tenure spatial improvement for the sustainable development. Substantiation is carried out for the transition economy with Ukraine as an example. Land redistribution aiming at urban settlement area optimization and agricultural land tenure in the context of the social environment and economic benefit has been substantiated. The effectiveness of the spatial land improvement in the context of the national and local budget land fee revenues has been substantiated.
WHAT MOTIVATES STAKEHOLDERS TO ENGAGE IN COLLABORATIVE INNOVATION IN THE INFRASTRUCTURE MEGAPROJECTS?
Authors: Chen Xiaoyan , He Qinghua , Zhang Xinyue , Cao Tingting , Liu Yan
Published: November 2021

Collaborative innovation has become an innovation paradigm to improve innovation performance and firms’ economic output. However, there is relatively little research investigating stakeholders’ drivers for engaging in collaborative innovation and the relative importance of drivers in infrastructure megaprojects. This research aims to address this gap by identifying the drivers for collaborative innovation and their relative importance in the context of infrastructure megaprojects. We adopt the literature review and questionnaire survey methods to identify drivers, the Relative Importance Index to rank them, and exploratory factor analysis to group them. The results show that 18 drivers are grouped into 6 dimensions. Their rankings are as follows: responding to project and clients’ requirements, improving efficiency, gaining rewards, learning, responding to competition, responding to environmental changes. The research contributes to stakeholders’ drivers to engage in collaborative innovation and the relative importance of drivers in the context of infrastructure megaprojects. Identifying and prioritizing stakeholders’ drivers can provide practitioners with suggestions on managing the collaborative innovation process in infrastructure megaprojects.
Planetesimals on Eccentric Orbits Erode Rapidly
Authors: Cedenblad Lukas , Schaffer Noemi , Johansen Anders , Mehlig B. , Mitra Dhrubaditya
Published: November 2021

We investigate the possibility of erosion of planetesimals in a protoplanetary disk. We use theory and direct numerical simulations (lattice Boltzmann method) to calculate the erosion of large—much larger than the mean-free path of gas molecules—bodies of different shapes in flows. We find that erosion follows a universal power law in time, at intermediate times, independent of the Reynolds number of the flow and the initial shape of the body. Consequently, we estimate that planetesimals in eccentric orbits, of even very small eccentricity, rapidly (in about 100 yr) erodes away if the semimajor axis of their orbit lies in the inner disk—less than about 10 au. Even planetesimals in circular orbits erode away in approximately 10,000 yr if the semimajor axis of their orbits are ⪅0.6 au.
The Structure and Stability of Massive Hot White Dwarfs
Authors: Nunes Sílvia P. , Arbañil José D. V. , Malheiro Manuel
Published: November 2021

We investigate the structure and stability against radial oscillations, pycnonuclear reactions, and inverse β-decay of hot white dwarfs. We consider the fluid matter to be made up of nucleons and electrons confined in a Wigner–Seitz cell surrounded by free photons. It is considered that the temperature depends on the mass density considering the presence of an isothermal core. We find that the temperature produces remarkable effects on the equilibrium and radial stability of white dwarfs. The stable equilibrium configuration results are compared with those for white dwarfs estimated from the Extreme Ultraviolet Explorer survey and the Sloan Digital Sky Survey. We derive masses, radii, and central temperatures for the most massive white dwarfs according to the surface gravity and effective temperature reported by the surveys. We note that these massive stars are in the mass region where general relativity effects are important. These stars are near the threshold of instabilities due to radial oscillations, pycnonuclear reactions, and inverse β-decay. Regarding the radial stability of these stars as a function of the temperature, we find that it decreases with the increment of central temperature. We also find that the maximum-mass point and the zero eigenfrequencies of the fundamental mode are determined at the same central energy density. Regarding low-temperature stars, pycnonuclear reactions occur in similar central energy densities, and the central energy density threshold for inverse β-decay is not modified. For T

c
≥ 1.0 × 108 [K], the onset of radial instability is attained before pycnonuclear reaction and inverse β-decay.
Ion Acceleration and the Development of a Power-law Energy Spectrum in Magnetic Reconnection
Authors: Che H. , Zank G. P. , Benz A. O.
Published: November 2021

How charged particles are accelerated efficiently and form a power-law energy spectrum in magnetic reconnection is a problem that is not well understood. In a previous paper, it was shown that the electron Kelvin–Helmholtz instability (EKHI) in force-free magnetic reconnection generates fast-expanding vortices that can accelerate electrons in a few tens of ion gyroperiods (less than 1 ms in the solar corona) to form a power-law energy distribution. In this paper, we present a particle-in-cell (PIC) simulation study of ion acceleration in force-free magnetic reconnection in the presence of the EKHI-induced turbulence. We find that ions are not significantly accelerated by the EKHI-induced stochastic electric field until the magnetic vortices expand to sizes comparable to the ion gyroradius. The Alfvén waves generated by the EKHI couple with the magnetic vortices, leading to resonance between the ions inside the magnetic vortices and Alfvén waves and enhanced ion heating. The induced Alfvén wave resonance results in a broken power-law energy spectrum with a breakpoint at

Time-dependent Treatment of Cosmic-ray Spectral Steepening Due to Turbulence Driving
Authors: Pohl Martin
Published: November 2021

Cosmic-ray acceleration at non-relativistic shocks relies on scattering by turbulence that the cosmic rays drive upstream of the shock. We explore the rate of energy transfer from cosmic rays to non-resonant Bell modes and the spectral softening it implies. Accounting for the finite time available for turbulence driving at supernova-remnant shocks yields a smaller spectral impact than found earlier with steady-state considerations. Generally, for diffusion scaling with the Bohm rate by a factor η, the change in spectral index is at most η divided by the Alfvénic Mach number of the thermal sub-shock. For M
A ≲ 50 it is well below this limit. Only for very fast shocks and very efficient cosmic-ray acceleration can the change in spectral index reach 0.1. For standard SNR parameters, it is negligible. Independent confirmation is derived by considering the synchrotron energy losses of electrons: if intense nonthermal multi-keV emission is produced, the energy loss, and hence the spectral steepening, is very small for hadronic cosmic rays that produce TeV-band gamma-ray emission.
Non-native plant drives the spatial dynamics of its herbivores: the case of black locust (Robinia pseudoacacia) in Europe

Published: November 2021

Non-native plants typically benefit from enemy release following their naturalization in non-native habitats. However, over time, herbivorous insects specializing on such plants may invade from the native range and thereby diminish the benefits of enemy release that these plants may experience. In this study, we compare rates of invasion spread across Europe of three North American insect folivores: the Lepidoptera leaf minersMacrosaccus robiniellaandParectopa robiniella, and the gall midgeObolodiplosis robiniae, that specialize onRobinia pseudoacacia. This tree species is one of the most widespread non-native trees in Europe. We find that spread rates vary among the three species and that some of this variation can be explained by differences in their life history traits. We also report that geographical variation in spread rates are influenced by distribution ofRobinia pseudoacacia, human population and temperature, thoughRobinia pseudoacaciaoccurrence had the greatest influence. The importance of host tree occurrence on invasion speed can be explained by the general importance of hosts on the population growth and spread of invading species.

The structure of scientific controversies: Thomas Kuhn’s social epistemology
Authors: Pirozelli Paulo
Published: November 2021

Changes of theories are major events in science. Two main types of questions may be asked about them: i) how do scientists choose new theories?, and ii) how is consensus formed? Generally, philosophers do not distinguish these two questions. Kuhn, on the contrary, offers very different answers to each of these questions. Theory-choice, on the one hand, is explained through the application of epistemic criteria, such as accuracy and consistency; nonetheless, because these values do not prescribe a single choice, consensus formation, on the other hand, is explained through a series of socio-epistemic mechanisms, namely: scientific pedagogy, diffusion and production of knowledge within the community (the “wave motion”), and restructuring of the scientific field. These mechanisms are the basis of Kuhn’s social epistemology, in that they are not restricted to sociology nor epistemology, encompassing both social interactions and epistemic evaluations of theories.
Keywords: Thomas Kuhn, consensus formation, social epistemology.
Una ciencia admirable: filosofía y admiración en Descartes
Authors: Raga-Rosaleny Vicente
Published: November 2021

Aunque Descartes pretende hablar de cuestiones morales en general, y de las pasiones en particular, como si nadie hubiera escrito antes sobre ellas, lo cierto es que, en el caso de la admiración, es clara su referencia al mundo antiguo. En concreto, en este caso el pensador francés se sitúa críticamente en contra de la postura aristotélica, que entiende la admiración como el inicio de la filosofía. Frente a la propuesta clásica, que convierte dicha emoción en el motor permanente de la investigación de las primeras causas, para Descartes la curiosidad excesiva y el estupor del asombro son rechazables. No obstante, algunos han señalado el carácter ambivalente de las declaraciones cartesianas. No en vano la admiración es no sólo la primera de las pasiones, sino también un componente fundamental de todas ellas. Y si bien en el campo del conocimiento debe superarse, en otros ámbitos, como el de la contemplación de la divinidad o en el goce de la libertad de la voluntad humana, tal desdén desaparece. En ese sentido, pretendemos explorar el modo en que Descartes separa admiración y conocimiento para luego reivindicar su importancia en el plano práctico.
Palabras clave: Admiración, asombro, curiosidad, libre albedrío, pasión.

Multi-Source Hybrid Energy Harvesting Wireless Sensor Network Framework for Addressing Energy Unpredictability Issues
Authors: Paul Aditi , Pandey Indu
Published: November 2021

Energy harvesting wireless sensor network (EH-WSN) harvests energy from the environment to supply power to the sensor nodes which apparently enhances their lifetime. However, the unpredictable nature of the resources throws challenges to the sustainability of energy supply for the continuous network operation. This creates a gap between unstable energy harvesting rates & energy requirements of the nodes of the network. The state-of-the-art algorithms proposed so far to address this problem domain are not able to bridge the gap fully to standardize the framework. Hence there is considerable scope of research to create a trade-off between EH techniques and specially designed protocols for in EH-WSN. Current study evaluates the performance and efficiency of some futuristic techniques which incorporate advanced tools and algorithms. The study aims to identify the strength and weaknesses of the proposed techniques which can emerge specific research requirement in this field. Finally, we propose a research direction towards Multi-source Hybrid EH-WSN (MHEHWSN) which is able to maximize energy availability and functional efficiency. The scope of this study is to develop a notion of a framework which eliminates the limitations of very recent techniques of EH-WSN by including multiple energy resources to extract required energy even in presence of unpredictability. However, keeping in mind the ease of use and less complex structure Multi-source hybrid EH technique requires a careful design paradigm.

Background: Bangladesh has been going through the austerity of the unique COVID-19 for more than a year like several other nations in the world in spite of concerted efforts taken by the government along with other concerned authorities who have advocated compulsory guidelines involving social distancing procedures accompanied by lockdown to have control over the pandemic. In this paper, the barriers faced by the government to protect people from the COVID-19 pandemic have been investigated. Also, the number of daily infected people against the number of daily tests has been underlined to comprehend the overall pandemic picture in Bangladesh.

Design and Methods: A descriptive study has been carried out to investigate the obstacles to tackle the COVID-19 pandemic for this country. The intensity of the outbreaks of the pandemic in this country is stated from March 8, 2020, to February 12, 2021. Secondary data have been employed from different sources to serve the goals of the study.

Results: The poor management in the health sector of Bangladesh has been an issue of major concern during the early stage of COVID-19 which incorporates deficiency of medical equipment, lack of facilities for testing COVID-19, poor patient management, and uncertainty in the medication system. Finally, some recommendations have been proposed for the concerned organizations to tackle the current pandemic and as well in the future.

Conclusions: To control this COVID-19 pandemic, it is necessary to find the difficulties and discover the remedies which have been done in this paper for the Bangladesh perspective.

Background

COVID-19 pandemic reached a public health emergency status of international concern. The impacts and events associated with this were associated with adverse psychological impacts among the general public globally. This cross sectional study aimed to determine the prevalence of psychological distress and to identify predictors associated with psychological distress due to the COVID-19 pandemic among the population in Myanmar.

Design and methods

A cross-sectional survey was conducted from March to April 2020 among adults, 18 years old and above, who reside in Myanmar through a structured questionnaire distributed in social media platforms. Univariate and bivariate analyses were used to estimate the prevalence of COVID-19 Peritraumatic Distress Index (CPDI) symptoms and to test the associations between CPDI and the exposure variables. Logistic Regression Analysis was done to identify significant predictors of distress. The statistical analysis used was Chi-square test and Multiple Logistic Regression Analysis.

Results

There were 530 participants in this study.37.4% of them did not have psychological distress, 55.6% experienced mild to moderate psychological distress, and 7% experienced severe psychological distress due to COVID-19 pandemic. Simple and Multiple Logistic Regression Analyses were performed to determine the factors associated with psychological distress due to COVID-19.

Conclusions

It was shown that the self-employed group and age group older than 45 years old had more psychological distress than others. However, Buddhists and people from the capital city had less distress than other religions and districts. This study recommends the government to develop better strategies for self-employed groups, elders, and the poor for a support, relief, and resettlement of their ruined status.

Cystic fibrosis (CF) is one of the most common recessive genetic diseases, with a wide spectrum of phenotypes, ranging from infertility to severe pulmonary disease. Mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene are considered the main genetic cause for CF. In this study, we recruited a consanguineous Iranian pedigree with four male patients diagnosed with congenital unilateral absence of the vas deferens (CUAVD), and one female patient diagnosed with congenital absence of the uterus (CAU). Testicular biopsy of one patient was performed, and hematoxylin and eosin (H and E) staining of testis sections displayed the presence of germ cell types ranging from spermatogonia to mature spermatids, indicating obstructive azoospermia. To explore the underlying genetic factor in this familial disorder, we therefore performed whole-exome sequencing (WES) on all available family members. WES data filtration andCFTRhaplotype analysis identified compound heterozygous mutations inCFTRamong four patients (two CUAVD patients carried p.H949Y and p.L997F, and one CUAVD and the female CAU patient carried p.H949Y and p.I148T). All these mutations were predicted to be deleterious by at least half of the prediction software programs and were confirmed by Sanger sequencing. Our study reported thatCFTRcompound heterozygous mutations in a consanguineous Iranian family cause infertility in both sexes.
