Les labels nationaux certifiant la responsabilité sociale de l’entreprise favorisent-ils une gestion des ressources humaines socialement responsable ? Exploration du contexte marocain
Authors: Jebli Fedwa , El Baz Jamal , Tremblay Diane-Gabrielle , Majdouline Ilias
Published: July 2021

La recherche analyse l’effet des labels nationaux de la RSE sur les pratiques GRH dans un pays en développement, soit le Maroc. L’étude qualitative montre que le caractère « national » du label RSE joue un rôle dans l’adhésion des entreprises à la labélisation. Toutefois et bien que les entreprises expriment un consentement vis-à-vis de la GRH socialement responsable (GRH-SR), parallèlement elles affichent une volonté d’instrumentaliser la RSE en négociant ou manipulant certaines exigences de la GRH-SR. De plus, l’accent mis par les entreprises sur le respect du droit du travail questionne la sincérité de leur démarche RSE.
On the Cauchy-Born approximation at finite temperature for alloys
Authors: Dai Shuyang , Wang Fengru , Yang Jerry Zhijian , Yuan Cheng
Published: July 2021

In this paper, we present the procedure of generalization and implementation of the Cauchy-Born approximation to the calculation of stress at finite temperature for alloy system in which the effects of inner displacement should be incorporated. With the help of quasi-harmonic approximation, a closed form of the first Piola-Kirchhoff stress is derived as a summation of pure deformation contribution and linear term due to thermal effects. For alloy system with periodic boundary condition, a further simplified formulation of stress based on some invariance constraints is derived in reciprocal space by using Fourier transformation, in which the temperature effect can be efficiently taking account. Several numerical examples are performed for various crystalline systems to validate our generalization procedure of finite temperature Cauchy-Born (FTCB) method for alloy.
Analysis of different interface treatments between masonry of AAC blocks and reinforced concrete structure after uniaxial compression strength test
Authors: Silva D.S. , Antunes E.G.P.
Published: July 2021

Autoclaved aerated concrete (AAC) masonry is widely used in civil construction but requires further investigation. Hence, this experimental study evaluated three types of interface treatment between the reinforced concrete structure and AAC masonry, in scale, after a uniaxial compression resistance test. The types of interface treatment considered are reinforcement with steel bars, with rough polymeric cementitious mortar, and without treatment. The maximum load capacity, displacements, and occurrence of cracks were analysed. The results showed that the maximum individual load capacity did not significantly differ among the examined groups. However, the analysis of the displacements and cracks showed that the group with steel reinforcement had the smallest displacements and largest cracks. This behaviour is owing to the greater solidarity of forces conferred by steel reinforcement.
Early-age compressive strength and dynamic modulus of FRC based on ultrasonic pulse velocity
Authors: Castillo D. , Hedjazi S.
Published: July 2021

Due to the increasing use of rapid construction methods and the challenges of maintaining construction schedules, a growing demand exists for procedures that can assure quality of work without sacrificing the pace of construction. The quality control of construction materials specifically, the mechanical properties of concrete are among the most important concerns in today’s construction industry. In the present study, the correlation between fiber-reinforced concrete’s compressive strength and dynamic modulus to its ultrasonic pulse velocity is investigated at early ages up to 7 days after mixing. An experimental program involving 189 FRC specimens were designed containing different types of structural fibers, fiber volume fractions, and water-to-cement ratios. Mathematical equations were developed to predict the early-age compressive strength and dynamic modulus of four different types of fiber-reinforced concrete based on ultrasonic pulse velocity. The predicted compressive strength and dynamic modulus from the proposed equations showed good agreement with the measured ones.
Lo que nos dejaron nuestros padres, nuestros abuelos»: retórica y praxis procesal alrededor de los usos y costumbres indígenas en la Nueva España temprana
Authors: Cunill Caroline , Rovira Morgado Rossend
Published: July 2021

El presente trabajo tiene como objetivo explorar las múltiples significaciones que revistió el concepto «usos y costumbres» indígenas en el contexto de reorganización cultural y política que el centro de México y Yucatán sufrieron en el siglo XVI. Para ello, se analiza un amplio abanico de fuentes, como diccionarios coloniales, manuales pastorales y de adoctrinamiento misionero, juicios y ordenanzas para el gobierno de tales pueblos de indios. Se concluye que el alto grado de flexibilidad conceptual y práctica de esta figura jurídica contribuiría tanto a consolidar el dominio colonial como a refrendar algunas reivindicaciones de las autoridades nativas.

Authors: Patard Guisela , Ouellet Frédéric
Published: July 2021

Les violences au sein du couple peuvent s’exercer de différentes manières (physique, sexuelle, psychologique, économique), varier en fréquence, en intensité et évoluer dans le temps. Pour faire face à ces violences, diverses stratégies peuvent être adoptées. La présente étude explore les stratégies de protection adoptées par 75 femmes ayant vécu au moins une forme de violence au sein du couple dans les trois années précédant l’entrevue. Le recueil des données s’est fait durant des entretiens en face-à-face à l’aide de questions fermées et de calendriers d’histoire de vie. L’objectif est de présenter un portrait des stratégies mises en place par les victimes pour minimiser la revictimisation. Lorsque la dynamique des événements n’est pas prise en considération, les résultats montrent une efficacité toute relative des mesures utilisées.
Relação entre Ansiedade Social Infantil e o Uso de Controle Coercitivo por Pais e/ou Cuidadores
Authors: Reis Maria Adelaide , Landim Ilana
Published: July 2021

Os modelos de parentalidade podem contribuir para a reprodução de padrões comportamentais adaptativos ou desadaptativos pelas crianças. Podem estar incluídas nesta última categoria condutas do tipo internalizante, as quais envolvem o transtorno de ansiedade social infantil. Este estudo pautou-se no embasamento teórico analítico-comportamental e objetivou identificar possíveis relações entre o uso do controle coercitivo por pais e/ou cuidadores e a ansiedade social na infância. Participaram da amostra 52 pais e/ou cuidadores de crianças com idades entre 8 e 12 anos (M=9,3; DP=1,7) sendo 53,8% (n=28) crianças do sexo feminino e 46,2% (n=24) do sexo masculino e seus respectivos responsáveis (M=38; DP=5,9). Foi solicitado aos responsáveis que respondessem no Google Forms um questionário sociodemográfico, a Escala Multidimensional de Ansiedade para crianças (MASC) e a Escala de Práticas Parentais (EPP). Os dados foram tabulados e analisados por meio de análises descritivas e correlacionais. Embora a maior parte dos respondentes não relatasse nenhum diagnóstico de ansiedade, afirmaram que seus comportamentos ansiosos influenciavam nas condutas dos filhos. Observou-se que crianças inseridas em contextos familiares que precarizam o apoio emocional, o incentivo à autonomia e a supervisão de comportamento e enfatizam o uso do controle coercitivo, tendem a manifestar maiores níveis de ansiedade social.
Professores/as de coragem: a escola nas disputas sobre o governo dos corpos
Authors: Torres Marco Antonio , Saraiva Izabella Marina Martinho
Published: July 2021

O presente artigo é resultado de uma pesquisa de mestrado que analisou como a escola tem se tornado um local de crescentes disputas sobre gênero e sexualidades. As fontes de pesquisas foram grupos focais com professores/as e um breve levantamento bibliográfico para contextualização e fundamentação das análises. A perspectiva teórica dialogou com as noções de discurso, governo e regime de verdade em Michel Foucault, bem como noções de gênero e reconhecimento em Judith Butler. As análises indicaram que a despeito da LGBTfobia presente nas escolas pesquisadas e dos ataques que sofrem professores/as acusados/as de propagar uma suposta “ideologia de gênero”, muitos/as deles/as, assumindo uma posição de coragem, têm sido importantes articuladores/as da resistência ao recrudescimento do discurso antigênero.
O Modelo de educação rural norte-americano para o Brasil: o Ponto IV (1955- 1959)
Authors: Martins Joira Aparecida Leite de Oliveira Amorim , Ferreira Nilce Vieira Campos
Published: July 2021

Este artigo visa investigar como o Ponto IV, um Projeto desenvolvido entre os anos de 1950 a 1960, estabeleceu uma possível transferência de modelos e formação educacional no meio rural brasileiro. Metodologicamente, a pesquisa analisa as publicações da Campanha Nacional de Educação Rural - RCNER, com foco nas ações e discussões sobre o “Ponto IV”, notadamente aquelas publicadas nos anos de 1955 a 1959, além de artigos científicos, páginas de website, entre outros. Conclui-se que, nas páginas da RCNER, o Ponto IV foi retratado como um projeto que tinha finalidade de "resolver" a o analfabetismo que grassava no meio rural, com a finalidade de “modernizar” as práticas agrícolas. Contudo, por trás desses intuitos o que efetivamente se buscava era influenciar e modificar as formas de viver dos rurícolas brasileiros, em suma, possibilitar uma influência dos modelos americanos de educação rural no Brasil, com uma pretensa promessa de “salvação” cheia de interesses não declarados.
Postnatal Ozone Exposure Disrupts Alveolar Development, Exaggerates Mucoinflammatory Responses, and Suppresses Bacterial Clearance in Developing Scnn1b-Tg+ Mice Lungs
Authors: Choudhary Ishita , Vo Thao , Paudel Kshitiz , Yadav Radha , Mao Yun , Patial Sonika , Saini Yogesh
Published: July 2021

Increased levels of ambient ozone, one of the six criteria air pollutants, result in respiratory tract injury and worsening of ongoing lung diseases. However, the effect of ozone exposure on the respiratory tract undergoing active lung development and simultaneously experiencing mucoinflammatory lung diseases, such as cystic fibrosis, remains unclear. To address these questions, we exposed Scnn1b transgenic (Scnn1b-Tg+) mice, a mouse model of cystic fibrosis–like lung disease, and littermate wild-type (WT) mice to ozone from postnatal days (PND) 3–20 and examined the lung phenotypes at PND21. As compared with filtered air (FA)–exposed WT mice, the ozone-exposed WT mice exhibited marked alveolar space enlargement, in addition to significant eosinophilic infiltration, type 2 inflammation, and mucous cell metaplasia. Ozone-exposed Scnn1b-Tg+ mice also exhibited significantly increased alveolar space enlargement, which was also accompanied by exaggerated granulocytic infiltration, type 2 inflammation, and a greater degree of mucus obstruction. The alveolar space enlargement in ozone-exposed WT, FA-exposed Scnn1b-Tg+, and ozone-exposed Scnn1b-Tg+ mice was accompanied by elevated levels of MMP12 protein in macrophages and Mmp12 mRNA in the lung homogenates. Finally, although bacterial burden was largely resolved by PND21 in FA-exposed Scnn1b-Tg+ mice, ozone-exposed Scnn1b-Tg+ mice exhibited compromised bacterial clearance, which was also associated with increased levels of IL-10, an immunosuppressive cytokine, and marked mucus obstruction. Taken together, our data show that ozone exposure results in alveolar space remodeling during active phases of lung development and markedly exaggerates the mucoinflammatory outcomes of pediatric-onset lung disease, including bacterial infections, granulocytic inflammation, mucus obstruction, and alveolar space enlargement.
Mononucleate da sangue periferico autologhe da filtrazione selettiva per il trattamento delle lesioni croniche dell’arto inferiore: Risultati a 4 anni
Authors: Bucalossi Matteo , Mariani Fabrizio
Published: July 2021

Recentemente è stato introdotto sul mercato una tecnologia a filtrazione selettiva per produrre un concentrato autologo di cellule mononucleate da sangue periferico (Peripheral Blood Mononuclear Cells, PBMNC) con indicazione d’uso per terapia cellulare umana. Le PBMNC trovano indicazione nel trattamento delle lesioni croniche degli arti inferiori. Lo scopo di questo studio è quello di valutare l’efficacia e la tollerabilità di tale trattamento in un gruppo di pazienti che presentavano ulcere cutanee degli arti inferiori, ad etiologia varia, non rispondono alle terapie topiche tradizionali ed avanzate. Lo studio è prospettico standardizzato. Sono state trattati 8 pazienti che presentavano in totale 22 ulcere cutanee ad etiologia variabile. Le PBMNC autologhe sono state impiantate lungo il decorso delle arterie tibiali di riferimento e nell’area peri-lesionale. Tutti i pazienti sono stati sottoposti ad un ciclo di tre infiltrazioni, eseguite in sala operatoria, con cadenza mensile, tranne un paziente che è stato sottoposto ad un quarto impianto, perché l’operatore ha ritenuto che uno ulteriore avrebbe accelerato lo stato già rigenerativo della cute stessa. Delle 22 ulcere trattate con tale metodologia, 14 sono giunte a guarigione completa entro un mese dalla fine dei tre impianti, mentre 8 sono andate verso un netto miglioramento. Tutti i pazienti hanno mostrato una buona compliance al trattamento e non sono stati registrati effetti avversi minori o maggiori. Il 50% dei pazienti trattati è stato sottoposto a follow-up a quattro anni dalla fine del trattamento, e solo una paziente ha avuto un’ulcera cutanea recidiva, ma in altra sede da quella iniziale. Le PBMNC, prodotte con sistema a filtrazione selettiva, si sono dimostrate un trattamento efficace delle lesioni croniche a diversa eziologia degli arti inferiori. La guarigione di tutte le lesioni cutanee trattate in tempi rapidi, la netta riduzione del dolore, e l’assenza di recidive a quattro anni suggeriscono un effetto clinico duraturo nel tempo.
Athletic Trainer–Reported Prevalence of Mental Health, Substance Use, and Barriers to Health in Secondary Schools
Authors: Beaupre Justin , Meske Sam W. , Buckley Meghan
Published: July 2021

Context

Where a person lives can have a significant effect on health. Limited access to health care, food insecurity, lack of affordable housing, and violence increase a person's likelihood of poor health. Athletic trainers (ATs) can contribute to identifying and improving the determinants of health that affect student-athletes.

Objectives

(1) What were the current perceptions ATs had about the health behaviors (specifically mental health and substance use) of high school student-athletes? (2) What were the barriers that ATs experienced when providing health services to high school student-athletes? (3) How did the developed environment affect the health behaviors and barriers that ATs observed?

Design

Qualitative study.

Setting

Online survey.

Patients or Other Participants

Certified National Athletic Trainers' Association members employed in the secondary school setting.

Main Outcome Measure(s)

Demographics of ATs were collected, and the ATs' perceptions of the health of student-athletes across developed environments, prevalence of mental health issues, tobacco and substance use, barriers to health care services, and housing and food insecurities among student-athletes were surveyed. Descriptive statistics for the outcome measures were reported.

Results

A total of 7600 electronic surveys were distributed to the ATs and 911 responded (females = 62%, average age = 36 years, average experience = 12.5 years). The school setting was identified by 82.5% as public and the environment as suburban by 43.7%, rural by 30.1%, and urban by 26.1%. Participants perceived a high average prevalence of mental health concerns (32%), e-cigarette use (31.7%), and marijuana use (26.9%) among student-athletes. Significant perceived barriers to health included limited access to transportation, poverty, and housing and food insecurities.

Conclusions

This study highlights the health disparities and barriers ATs observed when addressing the health care needs of student-athletes. Understanding the determinants of health in order to identify the causes of health disparities may better prepare ATs to manage the health needs of underserved student-athletes.
Validity of Urine Color Scoring Using Different Light Conditions and Scoring Techniques to Assess Urine Concentration
Authors: Wardenaar Floris , Armistead Scott , Boeckman Kayla , Butterick Brooke , Youssefi Darya , Thompsett Daniel , Vento Kaila
Published: July 2021

Context

Urine color (Uc) is used to asses urine concentration when laboratory techniques are not feasible.

Objective

To compare the accuracy of Uc scoring using 4 light conditions and 2 scoring techniques with a 7-color Uc chart. Additionally, to assess the results' generalizability, a subsample was compared with scores obtained from fresh samples.

Design

Descriptive laboratory study.

Samples

A total of 178 previously frozen urine samples were scored, and 78 samples were compared with their own fresh outcomes.

Main Outcome Measure(s)

Urine color and accuracy for classifying urine samples were calculated using receiver operating characteristics analysis, allowing us to compare the diagnostic capacity against a 1.020 urine specific gravity cutoff and defining optimal Uc cutoff value.

Results

Urine color was different among light conditions (P < .01), with the highest accuracy (80.3%) of correct classifications of low or high urine concentrations occurring at the brightest light condition. Lower light intensity scored 1.5 to 2 shades darker on the 7-color Uc scale than bright conditions (P < .001), but no further practical differences in accuracy occurred between scoring techniques. Frozen was 0.5 to 1 shade darker than freshly measured Uc (P < .004), but the values were moderately correlated (r = 0.64). A Bland-Altman plot showed that reporting bias mainly affected darker Uc without affecting the diagnostic ability of the method.

Conclusions

Urine color scoring, accuracy, and Uc cutoff values were affected by lighting condition but not by scoring technique, with greater accuracy and a 1-shade-lower Uc cutoff value at the brightest light (ie, light-emitting diode flashlight).
Computed Tomography-Derived Myosteatosis and Metabolic Disorders
Authors: Miljkovic Iva , Vella Chantal A. , Allison Matthew
Published: July 2021

The role of ectopic adipose tissue infiltration into skeletal muscle (i.e., myosteatosis) for metabolic disorders has received considerable and increasing attention in the last 10 years. The purpose of this review was to evaluate and summarize existing studies focusing on computed tomography (CT)-derived measures of myosteatosis and metabolic disorders. There is consistent evidence that CT-derived myosteatosis contributes to dysglycemia, insulin resistance, type 2 diabetes mellitus, and inflammation, and, to some extent, dyslipidemia, independent of general obesity, visceral fat, and other relevant risk factors, suggesting that it may serve as a tool for metabolic risk prediction. Identification of which muscles should be examined, and the standardized CT protocols to be employed, are necessary to enhance the applicability of findings from epidemiologic studies of myosteatosis. Additional and longer longitudinal studies are necessary to confirm a role of myosteatosis in the development of type 2 diabetes mellitus, and examine these associations in a variety of muscles across multiple race/ethnic populations. Given the emerging role of myosteatosis in metabolic health, well-designed intervention studies are needed to investigate relevant lifestyle and pharmaceutical approaches.
Differences in perceived parental stress between parents with very low birth weight infants and nurses in neonatal intensive care units, South Korea
Authors: Moon Seol-Hee , Park Ho-Ran , Kim Dong Yeon
Published: July 2021

Purpose: This descriptive study compared the perceived parental stress levels between parents with very low birth weight infants (VLBWIs) and nurses in the neonatal intensive care unit (NICU).Methods: In total, 83 parents of VLBWIs and 78 NICU nurses were enrolled. Data were collected with the Parental Stress Scale (PSS) and analyzed using the t-test and analysis of variance in SAS version 9.4.Results: The average PSS score was 3.31 among parents and 3.45 among nurses. The stress score was significantly higher among nurses with children (t=2.46, p=.016) and senior nurses (t=2.12, p=.037). There was a significant difference in the stress score according to parents' education (t=3.29, p=.002) and occupation (F=3.14, p=.049) in the sights and sounds subscale. Mothers had significantly higher stress scores than fathers in the parental role alterations subscale (t=2.32, p=.023). Parental stress scores were higher than those perceived by nurses in the infant's appearance and behaviors subscale for breathing patterns (t=2.95, p=.004), followed by jerky/ restless behavior (t=2.70, p=.008).Conclusion: Nurses should provide explanations to parents of VLBWIs in order to reduce parental stress about the appearances and behavior of VLBWIs. This is more important than aspect of the NICU environment and education about parental roles.

Authors: Dai Yi-Lin , Wei Jin-Song , Xu Jing , Li Ke , Wang Jing , Cha Ran-Ran , Kang Yu
Published: July 2021

Abstract

As an innovative in vitro culture model, organoids have been established by cell sorting and subsequent culture in three-dimensional culture systems. Organoids can be derived from induced pluripotent stem cells or organ-restricted adult stem cells. Compared with traditional two-dimensional cell culture models and patient-derived xenograft models, organoids possess long-term genetic stability and can better retain the characteristics of source tissues or organs. These advantages have led to the increased use of ovarian and fallopian tube organoids in various fields of research, including cell differentiation and development, establishment of disease occurrence and progression models, tissue regeneration and reconstruction, individual drug screening, immune cell co-culture, and maternal-fetal medicine. This review briefly summarizes the recent progress in the application of ovarian and fallopian tube organoids in the field of obstetrics and gynecology.
A rare case report of hypophysitis in pituitary macroadenoma mimicking pituitary apoplexy
Authors: Kowsalya Akkayasamy , Nachiappan Sivagami , Kumar Mahesh
Published: July 2021

Hypophysitis, a rare inflammatory disorder of the pituitary gland is often misdiagnosed as mass lesion. Granulomatous hypophysitis presenting clinically as pituitary apoplexy is rare. A 23-year-old woman with pituitary macroadenoma presented with sudden diminution of vision in the right eye with features clinically mimicking pituitary apoplexy. Imaging revealed pituitary macroadenoma with hypophysitis. After a course of high-dose intravenous corticosteroids, her visual acuity improved to 6/6. Although apoplexy and hypophysitis have subtle clinical and radiological differences, it is essential to differentiate them to avoid unnecessary invasive procedures when conservative treatment can suffice.

Authors: Grover Sandeep , Dua Devakshi , Sahoo Swapnajeet , Chakrabarti Subho
Published: July 2021

Background:

There are limited numbers of studies from India, which have evaluated the demographic and clinical profile of patients seen in the emergency setting.

Aim:

This retrospective study aimed to evaluate the profile of the patients, seen in the emergency setting by a psychiatry team.

Methodology:

The psychiatry emergency register was reviewed for the data for 6 calendar years (2014–2019), for the demographic and clinical profile.

Results:

5563 patients were evaluated by the emergency psychiatry team during the period of 6 years, with the number of patients seen in each calendar year varying from 693 to 1057. The mean age of the patients availing psychiatry emergency services was 38.35 years (standard deviation: 16.65), with a significant proportion (13.1%–16.7%) of them in the elderly age group. Majority of the patients were male (64.6%) and were seen initially by the medicine and allied branches (87.8%). The most common diagnosis was delirium, and this was followed by affective disorders. Substantial proportions of the patients had substance use disorders (18.5%) and self-harm (9.8%). Nearly four-fifths of the patients were managed with psychotropic medications, and nearly one-fifth were treated with psychotherapeutic interventions, while more than half underwent investigations.

Conclusion:

The present study suggests that delirium, followed by affective disorders, substance use disorders, and intentional self-harm are the most common psychiatric diagnoses, among patients seen in the emergency setting. These findings can have important implications for organizing the psychiatric services in the emergency setting and for training.
Technology-Based Psychosocial Management for Psychological Distress Due to Stigma Associated with COVID-19
Authors: Shetty Kannappa V , Sonkar Suruchi , Mahadevaiah Mahesh
Published: July 2021

COVID-19 is associated with a significant distress and stigma. Due to the nature of the disease, it is difficult to conduct counseling and therapy without taking significant precautions such as wearing a complete personal protective equipment kit which impedes with rapport and dampens the speech which is quite essential for therapy. Herewith, we present a case where we used technology-based interventions, course, and outcome. Although the results of this case study cannot be generalized, few factors clearly stand out in the treatment of psychological distress among COVID-19-positive clients – psychoeducation, supportive therapy components of Cognitive Behavioral Therapy (CBT), and management of expressed emotion may play a key role in dealing with rural population. Family interventions were used to facilitate healthy family communication pattern (using technology) toward healthier involvement, connectedness aid client's recovery in the aftermath and acceptance of COVID-19 diagnosis. Intervention should also equip and empower client and family to deal with stigma and helplessness through clarifying misconceptions, providing knowledge, and enhancing agency or mastery over circumstances. These can serve as guidelines during treatment of psychological distress among COVID-19-positive clients and their families.

Authors: Grover Sandeep , Goyal Sandeep Kumar , Sahoo Swapnajeet , Goyal Samta , Mehra Aseem
Published: July 2021

Aim of the Study:

To evaluate the views of medical students about online classes started in view of COVID-19 pandemic.

Methodology:

An online survey was conducted using Survey monkey platform®. A survey link which was sent through the WhatsApp platform® to the MBBS/BDS students across the country. The survey questionnaire evaluated the views about the various aspects of the online classes.

Results:

A total of 1059 students completed the survey, of which 1033 entries were analyzed. The participants' mean age was 20.8 years with nearly equal male-to-female ratio, majority being MBBS students who were taking part in online classes mostly from home (95.4%), by using smart phones (85%). When asked to compare the experience of online classes with regular in-person classes, a majority of the participants reported having poor attention and concentration, poor retention of knowledge, poor learning of theoretical aspects of subject, poor learning of practical aspects of the subject, poor questions/answers sessions, and only 38.9% and 10.6% rated online theory and online practical classes as 'good' or 'very good,' respectively. The most common advantages of online classes reported by the students were that they do not have to travel (69%) and do not have to dress up (69.9%), while the most commonly reported disadvantages included poor learning of practical aspects (75%), followed by strain on eyes (73.4%) and difficulties with internet connectivity (64.8%). A small proportion of students 'occasionally' or more often indulged in surfing Internet, Chatting on WhatsApp/Telegram/FB Messenger, and using Social Media (Facebook, Instagram, We Chat, Snap Chat, and Telegram) while attending online classes.

Conclusions:

This study suggests that although various colleges are running online classes, as a substitute for the regular in person classes in view of the need for social distancing, these classes are not well received by the students and are possibly does not fulfilling the desired needs of the students. Further, the present study suggests that students still prefer in-person classes.

Известно также, при каких $\varepsilon$ множество разумных дележей
принадлежит $\varepsilon$-ядру. Тогда и $\varepsilon$-ядро
будет непусто. Этот результат представляет значительный интерес,
поскольку 0-ядро кооперативной игры может быть пустым,
однако если при этом $\varepsilon$-ядро не пусто при некотором малом
$\varepsilon>0$, то существуют дележи, которые по своим свойствам
мало отличаются от дележей из 0-ядра. Данные результаты

Foundations of Online Structure Theory II: The Operator Approach
Authors: Downey Rod , Melnikov Alexander , Ng Keng Meng
Published: July 2021

We introduce a framework for online structure theory. Our approach
generalises notions arising independently in several areas of computability
theory and complexity theory. We suggest a unifying approach using operators
where we allow the input to be a countable object of an arbitrary complexity.
We give a new framework which (i) ties online algorithms with computable
analysis, (ii) shows how to use modifications of notions from computable
analysis, such as Weihrauch reducibility, to analyse finite but uniform
combinatorics, (iii) show how to finitize reverse mathematics to suggest a fine
structure of finite analogs of infinite combinatorial problems, and (iv) see
how similar ideas can be amalgamated from areas such as EX-learning, computable
analysis, distributed computing and the like. One of the key ideas is that
online algorithms can be viewed as a sub-area of computable analysis.
Conversely, we also get an enrichment of computable analysis from classical
online algorithms.

This article defines vertebra-related causes of vertebrobasilar insufficiency in patients with the signs of tortuosity of segment VI of the VA. The aim of this study is to present the results of diagnostics of discirculatory phenomena in the vertebrobasilar system and to show their importance for differentiated surgical treatment of stenotic lesions of segment V1 of VA in pathological disorders of cerebral circulation in the VBS caused by osteochondrosis of the cervical spine. The following traditional methods are used in diagnostics: Doppler ultrasonography, multispiral computed tomography with contrast enhancement. Also using developed by the author method for determining VA reactivity and circulatory insufficiency in the vertebrobasilar system (VBS). Based on our methodology and criteria, patients were selected for different types of surgical treatment with clinical outcome prediction following interventions on the arteries of the VBS. To determine the pathologies of the intracranial segments of the vertebral and basilar arteries, taking into account the pathways of collateral compensation in the VBS, cerebral angiography is recommended before surgery on the arteries of the VBS. Reconstructive techniques used on segment VI of the VA will predictably show the best long-term clinical results. The excision of a tortuous segment VI of the VA may be effective in obtaining reliable results of successful interventions in the early postoperative period. The conservative treatment of the patients with multiple VBD lesions is possible. early outcomes of their use are satisfactory.

The study of the possibilities of modelling the use of neural networks while increasing the efficiency of diagnostic systems consists of creating a standard that would satisfy the conditions for maintaining the sound quality. At the same time, the effectiveness of diagnostic systems can be considered when applied both in a technological environment and in a virtual space. The relevance of the study is determined by the possibilities of using the reference sound, which forms and uses the basis of the neural networks. The scientific novelty of the study is determined by the fact that an adaptive method for creating standards of units of measurable quantities with specified accuracy characteristics is proposed, subject to limited resources. The first version of the mathematical model of the measurement procedure is formed during reproduction, storage and transmission of a unit of measurement developed on the basis of a physical model, which, in turn, is built in accordance with a priori information on the principle of reproduction (storage and transmission) of a unit of measurement, a list of informative parameters and influential quantities when measuring. The authors have developed the necessary accuracy characteristics, specified by the technical specifications and determined the resources allocated for the creation of the standard. The practical significance of the study lies in the establishment of distributed networks for sound quality measurement, mainly within the structures of the study of sound transmission between high-tech devices.

The article deals with the main problems of protection of property rights under conditions of external military aggression in Ukraine. The authors, with the example of a separate case, analyses the problematic aspects of renewing and granting property rights to citizens residing in the temporarily occupied territory of Ukraine. Methodologically, it is a documentary research. It is concluded that the law and judicial practice of the protection of property rights in the example of the right to compensation for damaged homes may prove insufficient on its own. The weaknesses of Ukrainian legislation in compensation for damage caused to citizens in conditions of armed conflict and terrorist activity are discussed in detail. Finally, it emphasizes the role of transitional justice in improving the law and practice of resolving disputes overcompensation for moral and material damage under the conditions of occupation of certain territories of Ukraine.

The modern stage of development of state financial systems is characterized by difficulties in ensuring national financial security. Despite the urgency of this problem, the international community is focusing on ensuring economic security during the formation of universal and regional legal instruments, leaving out of sight issues of legal and practice-oriented guidance in financial security. The article examines the main directions of implementation of state policy aimed at improving the effectiveness of legal and national and international means to ensure financial security in the context of the globalization of growing threats to economic security. The focus is on the modernization of legal instruments to regulate public relations related to financial security. Particular attention was paid to the correlation of international legal bases, national legislation, and regional laws. It is concluded that the development of state financial policy that guarantees the security of the budgetary system is fundamental.

The article deals with the role of constitutional complaint in the system of quality assurance of the state legislation, for protection of the rights and freedoms. Constitutional complaints, as well as their optimal models, require detailed research. Comparative analysis and survey are the main methods. The subject of a constitutional complaint in the model proposed by the authors may be laws or their individual provisions, regulations of heads of state, government, other statutes and regulations, individual administrative acts, judgements in specific cases. Citizens, foreigners, stateless persons, and legal entities are subjects who have the right to file a constitutional complaint. The authors attribute the following conditions of admissibility of a constitutional complaint: the presence and proof of violation of his/its constitutional rights and freedoms, the use of all other remedies to protect violated rights and freedoms, compliance with deadlines for filing a constitutional complaint in some countries, and payment of state duty. The model proposed by the authors is, however, universal, and further needs to be detailed for countries of interest.

Evangelizar en tiempos de increencia
Authors: Núñez Aguilera Miguel Ángel
Published: July 2021

Inmersos en un ambiente sociocultural impregnado por la increencia, el creyente se encuentra hoy fuertemente confrontado: convocado para anunciar a Dios a sus contemporáneos, y a un tiempo persistentemente rechazado por ello. De ahí que sea una urgencia reflexionar sobre cuáles son las claves antropológicas del hombre contemporáneo que le han conducido a tal cerrazón en su estructura íntima hasta instalarlo en la increencia. El presente artículo aborda no sólo en el por qué el anuncio cristiano no interesa al hombre contemporáneo, sino, más radicalmente, por qué Dios ha dejado de ser significativo al hombre. Y también algunas consideraciones desde donde proponer la fe hoy, alcanzar nuevos caminos para el anuncio del Evangelio.
