Awareness and perception of COVID-19 among the general population: A Middle Eastern survey
Authors: Jaber Ruba M. , Mafrachi Baraa , Al-Ani Abdallah , Shkara Mustafa
Published: April 2021

Due to the sudden emergence of the novel coronavirus as a worldwide pandemic, this study aimed to evaluate the awareness and practices of both the Jordanian and Iraqi populations during the early stages of the pandemic. A cross-sectional survey was conducted between the 19th and 22nd of March to assess the public’s awareness toward COVID-19. Multiple scored domains were used to assess the differences between the two populations. Statistical analysis was conducted to reveal the influence of sociodemographic variables on these scores. A total of 3167 participants were recruited in the study, of which, 1599 (50.5%) were from Jordan and 1568 (49.5%) were from Iraq. More than half of the Jordanian (56.8%) and Iraqi participants (53.2%) showed average or adequate awareness about COVID-19. More than 60% of both populations relied on medical staff for COVID-19 related information. Social media was the second most common COVID-19 information source, as it was reported by 53.7% of Jordanian participants and 62.8% of Iraqi participants. More than 90% of both populations participated in precautionary measurements. Finally, about 20% of both populations failed to recognize droplet inhalation as a source of transmission. Despite the portrayed awareness levels, governmental involvement is warranted to increase the public’s awareness and fill the gaps within their knowledge.

Tacrolimus (Tac) is an effective remission inducer of refractory ulcerative colitis (UC). Gene polymorphisms result in interindividual variability in Tac pharmacokinetics. In this study, we aimed to examine the relationships between gene polymorphisms and the metabolism, pharmacokinetics, and therapeutic effects of Tac in patients with UC. Forty-five patients with moderate-to-severe refractory UC treated with Tac were retrospectively enrolled. Genotyping for cytochrome P450 (CYP) 3A4*1G, CYP3A5*3, CYP2C19*2, CYP2C19*3, nuclear receptor subfamily 1 group I member 2 (NR1I2)–25385C>T, ATP-binding cassette subfamily C member 2 (ABCC2)–24C>T, ABCC2 1249G>A, and ABCC2 3972C>T was performed. Concentration/dose (C/D) ratio, clinical therapeutic effects, and adverse events were evaluated. The C/D ratio of Tac in UC patients with the CYP3A4*1G allele was statistically lower than in those with the CYP3A4*1/*1 allele (P = 0.005) and significantly lower in patients with CYP3A5*3/*3 than in those with CYP3A5*1 (P < 0.001). Among patients with the CYP3A4*1G allele, the C/D ratio was significantly lower in patients with CYP3A5*1 than in those with CYP3A5*3/*3 (P = 0.001). Patients with the NR1I2–25385C/C genotype presented significantly more overall adverse events than those with the C/T or T/T genotype (P = 0.03). Although CYP3A4*1G and CYP3A5*3 polymorphisms were related to Tac pharmacokinetics, CYP3A5 presented a stronger effect than CYP3A4. The NR1I2–25385C/C genotype was related to the overall adverse events. The evaluation of these polymorphisms could be useful in the treatment of UC with Tac.

The Study of Symmetry Energy in Pasta of Neutron Star From Compressible Liquid Drop Model Approximation
Authors: Sulistyani Eko Tri , Ananda Rizky
Published: April 2021

The properties of pasta which is located at the bottom of inner crust from neutron star has been studied by using compressibl e liquid drop model. Compressible liquid drop model is a modified liquid drop model as a density function. Liquid drop model based on assumption that the magnitude of nucleus bonding energy is contribution of surface, Coulomb, volume, symmetry, and proton -neutron pair effect. Pasta of neutron star behaves like liquid crystals (mesomhorpic phase). The top layer of pasta filled by free neutron gas, while in the lowest layer of the pasta is filled by proton-neutron gas. The properties of pasta are observed at temperatures close to zero Kelvin with the assumption that neutron star is on ground state and non accretion. The study of pasta emphasizes on symmetry energy’s influence. Symmetry energy reduces the magnitude of bonding energy of nucleon in the nucleus and it causes nucleon to be more easily released from nucleus. After that, symmetry energy influence the properties of pasta, such as the shape of nucleus that is non spherical (some like plates, rods, and bubbles), the fluctuative values of Wigner-Seitz cell, and uneven distribution of protons and neutrons in the pasta region of neutron star.

The Study of Modified Semi-Empirical Mass Formula (SEMF) by Considering Isospin Effects in Liquid Drop Model
Authors: Sakinah Sinta Ayu , Sulistyani Eko Tri
Published: April 2021

We do theoretically study of Modified Semi-Empirical Mass Formula (SEMF) based on macroscopic approach in liquid drop model by considering isospin effects. Isospin is one of internal symmetry properties in hadron group, particularly the nucleon multiplet, it represented by SU(2) isospin group. Hadron is a group of elementary particles take place in the strong interaction. The role of strong interactions represents homogeneous nuclear force, interactions between proton-proton (Fpp) , proton-neutron (Fpn), and neutron-neutron (Fnn) are  same. In other words, protons and neutrons are indistinguishable because mass (energy) between protons and neutrons is almost the same, by removing charge between them (charge independent). The dependence of isospin effects on nuclear symmetry term and odd-even (pairing) term  made the formulation of  SEMF should be modificated, in order to obtain nuclear mass and binding energy of a nucleus close to the experimental results. We do two accuracy testing. First, by comparing |Mexp - Mth| for nuclei Pb82208 using SEMF before and after being modified, the result shows that using SEMF before modification the value of |Mexp - Mth|≈ 0,0204 u and for modified SEMF we obtained |Mexp - Mth|≈ 0,0203 u at k=12 . The value of |Mexp - Mth| for modified SEMF is smaller than before modification, it indicates that Modified SEMF is a good formula to calculate the mass of nuclei. Second, by comparing Modified SEMF with other models such as FRDM, HFB-14, and HFB-17 using accuracy parameter in the form of rms deviation   and number of model parameters   ). The results show that rms deviation   decrease 21% to 0,516 and number of model parameters    ) decrease to 15, consists of 13 macroscopic model parameters    and two microscopic model parameters      and �). The value of model parameters was obtained by fitting to experimental results, as a reason it is called semi-empiric.

“Does Brexit mean Brexit?” “Ave, Bruselas, brexituri te salutant”
Authors: Fernández Cadavid José Luis
Published: April 2021

Una amplia mayoría de ciudadanos de la UE muestra un gran desinterés por los asuntos que conciernen a esta. De hecho, instituciones como la CECA, la CEE, el EURATOM o tratados como el de Maastricht, Ámsterdam, Niza o Lisboa raramente son temas de conversación. Tan solo el proceso de salida del Reino Unido despierta cierta preocupación, ya que se percibe que alguna influencia tendrá sobre nuestras economías. Se habla de Brexit, de withdrawal agreement, de backstop, etc., aunque sin llegar al fondo de estos conceptos. Desde su creación, la UE no ha parado de avanzar en la construcción de su proyecto de integración. Los gobiernos británicos no parecen haberse identificado del todo con el objetivo último del proceso: la unión política. Así pues, partiendo de una breve historia de la Unión, nos adentraremos en el evento de la Brexit, analizando lo que han supuesto estos cuatro años, tanto para la UE como para el RU, hasta la llegada del “huracán Johnson”, con sus controvertidas y polémicas decisiones.

Augustus için söz konusu eyalet sadece Roma’nın yabancı bir düşmana karşı kazandığı zafer değil aynı zamanda kendi iktidarını ve gücünü Roma’ya karşı kanıtladığı bir iç savaşın galibiyetiydi. Mısır, Augustus’un tüm yetkileri eline almasıyla kişisel bir alanı haline geldi. Bundan dolayıdır ki Augustus, yeni eyalette hiçbir eyalet için alınmayan tedbirleri aldı ve düzenlemeler yaptı. Eyalette, yapmış olduğu reformist icraatları Roma’nın emperyal yayılımının nitekim çarpıcı örnekleridir. Pek çok alanda değişimlerin uygulandığı Mısır’da hukuk alanında da düzenlemeler yapıldı.
Bu makalede amacımız, Mısır’ın Roma Eyaletine dönüştürülmesiyle uygulanan hukuksal değişimleri değerlendirmektir. Çalışmamızda sadece İÖ 30-İS 14 yılları Augustus Dönemi’ni ele almamızın sebebi, çalışma konumuzu, Roma’nın da aynı zamanda kendi iç siyasetinde yaşadığı değişimler çerçevesinde değerlendirmektir.

Bilinçli bir varlık olan insan nesiller boyu dönemlerini şekillendiren fikirler üretmişlerdir. Birlikte yaşamın getirdiği sorunlarla mücadele etme çabaları, toplumları ideal düzen arayışına itmiştir. Ortaya çıkan fikirler edebiyatta yazınsal olarak gelişmiştir. Dönemlerinin eleştirisi niteliğinde olan ve çözüm önerisi sunmaya çalışan ütopyalar, 19.yy’da endüstri devriminin yarattığı kaosa karşılık mimarlıkta yansımalarını bulmuştur. İlk olarak mimari ürünlerle somutlaştırılmaya çalışılan ütopyalar, 20.yy’da sinema sanatının çıkışıyla beraber sistematik olarak görselleştirilmeye başlanmıştır. Döneminin sorunlarını çözebilme kaygısı olan, geleceğin formlarını ve/veya fonksiyonlarının değişimini bilimsel/teknolojik gelişmelerle tasarlayabilme mimarlık ütopyalarını oluştururken, sinemada bu ütopyalar, distopyalar olarak bilim kurgu filmleriyle nesnelleşmiştir. Ütopik mekan kurgusunu yansıttığı düşünülen örnek filmler seçilmiş ve çıkarımlar yapılmıştır.

Madde kullanma ve bağımlılık sorununun bireysel alanı aşan etkileri, sorunu sosyal problem düzeyine çıkarmaktadır. Bu nedenle sorunun anlaşılması ve çözümüne katkı sunulması da önem arz etmektedir. Bu makalede uyuşturucu madde bağımlılarının demografik özellikleri ve madde kullanım alışkanlıkları ele alınmıştır. Çalışmanın örneklemi inanç temelli programlar aracılığıyla bağımlılıklarından kurtulma mücadelesi veren gönüllü kişilerden oluşmaktadır. Makale, nitel ve nicel araştırma yöntemlerinin birlikte kullanıldığı uygulamalı bir çalışmanın bulgularını değerlendirmektedir. Sonuçlar madde kullanımının ekseriyetle adolesan dönemde başladığını, yirmili yaşlarda, bağımlılıkla mücadele kaygılarının ve çabalarının en yüksek düzeye ulaştığını, madde kullanmaya başlamada, kullanmayı sürdürmede ve bırakmada sosyal çevrenin önemli bir etken olduğunu göstermektedir. Şiddet/istismara maruz kalmanın madde kullanma riskini arttırdığı ve madde kullanma alışkanlığına birçok riskli davranışın eşlik ettiği de sonuçlara yansımıştır. Katılımcılar arasında bir maddeden diğerine geçmek şeklindeki değişen/çoklu madde kullanımının yaygınlığı, madde kullanım davranışında korkunun önemli bir faktör olduğu, bağımlılar arasındaki dayanışmanın madde temini ve kullanımın sürdürülmesinde önemli bir etken olduğu ortaya çıkmıştır.

Published: April 2021

Malatya’nın Arapkir ilçesine bağlı Onar köyü Arapkir’e 15 km mesafede olup Malatya – Arapkir karayolunun 5 km doğusunda kalmaktadır.
Bir Türkmen yerleşimi olan köyde iki adet zaviye (cem evi), baldeken bir yapı ve bir çeşme bulunmaktadır. Zaviyeler 13. Yüzyıla tarihlenmekte olup bunlar tüteklikli (kırlangıç kubbeleri ile dikkat çekmektedir. Tüteklikli örtünün etrafında dolanan koridor ile işlevleri farklılık gösterse bile Kubbetüs Sahra ve Bursa II. Murat türbeleri ile benzerlik göstermektedir. Tüteklikli örtünün kullanım alanı yaygın bir coğrafyada yayılmış olsa da Malatya ve çevresinde nadir görülen bir uygulama olarak karşımıza çıkmaktadır.
Ayrıca baldeken yapı olarak adlandırdığımız eser günümüzde bir çamaşırhane mekanı gibi kullanılsa da bu yapımızın mimari formu türbe mimarisinde yaygın kullanım alanı bulmuştur. Zamanla değişime uğrayan yapının benzer örnekleri Malatya ve çevresinde türbe mimarisinde uygulandığı görülmektedir. Bu sebepten dolayı bu yapının bir türbe olma olasılığı kuvvetlidir.
Oner Köyünde bulunan bir diğer yapı ise çeşme olup geç dönem onarımlarına tabi tutulduğu üzerindeki kitabeden anlaşılmaktadır. Basit bir çeşme nişinden ibaret tek cepheli sokak çeşmeleri formunda ele alınmıştır.
The potential of the CEFR for languages descriptors for mediation in an
ESP CALL-based context
Authors: Korai Maria , Papadima-Sophocleous Salomi
Published: April 2021

The present case study investigated the potential of the Common European
Framework of Reference (CEFR) for languages: learning, teaching, assessment
can-do descriptors for mediation in an English for Specific Purposes (ESP)
Computer-Assisted Language Learning (CALL)-based context. Fabricating
descriptors for mediation was cardinal for the Council of Europe’s (2018)
endeavour in updating the CEFR Companion. Despite surfacing just as a
language skill in the 2001 CEFR Companion, mediation is now viewed as a
central mode of communication in the New CEFR Companion, both in the
receptive and productive modes. As they were just introduced in 2018, the
CEFR mediation descriptor scales have not yet been sufficiently explored.
The main goal of the present research was to fill some of this gap in the
literature by investigating the potential of the CEFR for languages
descriptors for mediation in an ESP CALL-based CEFR B2 tertiary level
context (a 13 week ESP course specifically designed to meet the needs of
university Rehabilitation Sciences students.) Data collection tools included
students’ self-assessment against can-do descriptors for mediation,
observation, student reflections, and focus group interviews. The findings
suggest that the implementation of the existing course activities had the
potential to promote mediation processes. The significant role of mediation
in carrying out the course activities in addition to the CALL component of
the ESP course activities highlighted the potential of CALL technologies to
trigger, support, and promote mediation processes; this finding stressed the
underlying role of the nature and the structure of the ESP course’s
CALL-Based activities in supporting mediation processes.
Cost savings of outpatient versus standard inpatient total knee arthroplasty
Authors: Huang Adrian , Ryu Jae-Jin , Dervin Geoffrey
Published: April 2021

Background: With diminishing reimbursement rates and strained public payer budgets, a high-volume inpatient procedure, such as total knee arthroplasty (TKA), is a common target for improving cost efficiencies. Methods: This prospective case–control study compared the cost-minimization of same day discharge (SDD) versus inpatient TKA. We examined if and where cost savings can be realized and the magnitude of savings that can be achieved without compromising quality of care. Outcome variables, including detailed case costs, return to hospital rates and complications, were documented and compared between the first 20 SDD cases and 20 matched inpatient controls. Results: In every case–control match, the SDD TKA was less costly than the inpatient procedure and yielded a median cost savings of approximately 30%. The savings came primarily from costs associated with the inpatient encounter, such as surgical ward, pharmacy and patient meal costs. At 1 year, there were no major complications and no return to hospital or readmission encounters for either group. Conclusion: Our results are consistent with previously published data on the cost savings associated with short stay or outpatient TKA. We have gone further by documenting where those savings were in a matched cohort design. Furthermore, we determined where cost savings could be realized during the patient encounter and to what degree. In carefully selected patients, outpatient TKA is a feasible alternative to traditional inpatient TKA and is significantly less costly. Furthermore, it was deemed to be safe in the perioperative period.
Informed consent for surgery: risk discussion and documentation
Authors: Hanson Melissa , Pitt Dennis
Published: April 2021

Informed consent for surgery has become a critical component of surgical practice. There are specific legal requirements for what has to be disclosed to patients and for the accompanying documentation. The hospital consent for surgery form with the patient’s signature is a small part of the process. A quality assurance review of the documentation of informed consent by our surgical group indicated major deficiencies and prompted this article (and its Appendix containing further information). Our intent was to inform surgeons about modern standards and to discuss particular challenges. Informed consent for surgery entails what surgeons communicate to their patients about the proposed surgery and is a key element in the trust patients have in surgeons. It is of increasing importance, and we must keep up to date with patient and legal expectations.
Reflections on recovery, rehabilitation and reintegration of injured service members and veterans from a bio-psychosocial-spiritual perspective

Published: April 2021

Medical interventions regarding trauma resuscitation have increased survivorship to levels not previously attained. Multiple examples from recent conflicts illustrate the potential return to high-level function of severely injured service members following medical and rehabilitative interventions. This review addresses the goals of rehabilitation, distills hard-won lessons of the last decade of military trauma and rehabilitation, and recommends the use of a bio-psychosocial-spiritual approach to care that can be applied at all tiers of the health care system. Questions on enabling participation in meaningful life activities include the following: Why do some patients do well and others do not? What elements contribute to positive outcomes? What factors relate to suboptimal results? Lessons learned revolve around the importance of considering the physical, psychosocial and spiritual aspects of a person’s well-being; empowering patients by fostering self-efficacy; and helping patients find meaning in life events and set high-level goals. A bio-psychosocial-spiritual model from the rehabilitation medicine literature — the Canadian Model of Occupational Performance and Engagement — is proposed as a guide to the provision of person-centred care and the maximization of a person’s functioning posttrauma.
Jelena Osnobkina (1959–2010)
Authors: Motroschilowa Nelly
Published: April 2021

This archival feature serves to present the personality and philosophy of Elena Oznobkina (1959–2010), a key figure of late-Soviet and, later, Russian philosophy. Oznobkina pioneered the present-day reception of Martin Heidegger and Edmund Husserl in Russia, but also made substantial contributions to Nietzsche studies and political philosophy, which are detailed in Nelly Motrozhilova’s introduction. Her philosophical work was inseparable from her personal political engagement, to which the featured archival text (“Prison or Gulag?”, 2000) testifies. It gives a poignant and concise characterisation of the prison as an object of philosophical theory, while asking the question of where Soviet prison camps and the prisons of post-Soviet Russia are to be located within this field of thought.
Square DRA feed for parabolic reflector antenna for satellite communication application

Published: April 2021

A square dielectric resonator antenna (SDRA) offering high polarization purity as a feed for parabolic reflector antenna is presented in this paper. Three sequences of holes are strategically integrated into the SDRA to enhance the polarization purity of the desired mode by suppressing the cross-polarization (X-pol) generating higher order mode. A detailed study on the performance of the parabolic reflector antenna with the proposed SDRA feed is also performed. The composite structure provides low X-pol levels of −33 dB at the half-power beamwidth (HPBW) points and −35 dB at the 1 dB co-polarization region in the H-plane. The composite structure radiates in the broadside direction with a high gain of 26 dBi and radiation efficiency of 95%. The proposed SDRA is designed to operate at 3 GHz of the S-band. A prototype of the proposed design is fabricated and experimentally verified. A measured X-pol isolation of 39 dB at ±15% of HPBW (European Telecommunication Standards Institute [ETSI] standard for satellite communication) and 50 dB at boresight is obtained in the H-plane. The small size, light weight, stable radiation performance and high polarization purity offered by the proposed SDRA make it a suitable candidate for satellite communication application.
500 Jahre Rezeption der Reformation in Siebenbürgen und Ungarn: Anfänge und Netzwerke von Konfessionspluralismus in der Überlappungszone von West- und Ostkirche
Authors: Wien Ulrich A.
Published: April 2021

This thematic issue of the Journal of Early Modern Christianity focuses on the reception of the Reformation in Transylvania and especially on the development of Protestant churches oriented towards Luther and influenced by Melanchthon. In the late Middle Ages, Transylvania had become part of the cultural influence zone of Central Europe, but throughout the sixteenth century the region became permeated by religious developments in Western Europe too. Here, a very peculiar constellation of religious pluralism and co-existence emerged, and the different contributions examine the premises and networks behind these dynamics. In this joint effort, it becomes clear how Transylvania turned into a pioneer region of religious freedom, as it witnessed simultaneously the development of Catholic, Orthodox and various Protestant confessional cultures.
Transient neonatal hyperinsulinism: early predictors of duration
Authors: Fuchs Shai , Regev Ravit , Harrington Jennifer
Published: April 2021

Objectives

Hyperinsulinism is the most common cause of recurrent hypoglycemia in infants, with transient and permanent forms. Currently, there are no effective tools to predict severity and time to resolution in infants with transient hyperinsulinism (tHI). Therefore, our objective was to assess whether early glucose trends predict disease duration in tHI.

Methods

A retrospective, pilot cohort of infants admitted with tHI was phenotyped for clinical and laboratory parameters. Blood glucose (BG) values were collected from the first documented hypoglycemia for 120 h (five days).

Results

In 27 neonates with tHI, the presence of fetal distress (p=0.001) and higher mean daily BG (p=0.035) were associated with shorter time to resolution of hypoglycemia. In a further sensitivity analysis that grouped the cohort by the presence or absence of fetal distress, we found that in neonates without fetal distress, lower mean daily glucose was associated with longer disease duration (R2=0.53, p=0.01).

Conclusions

Our pilot data suggests that predictors for disease duration of tHI may be elicited in the first week of life, and that tHI associated with fetal distress may represent a distinct clinical entity with a shorter time course.
