Published: June 2022

Desde a segunda metade do século XX muitas têm sido as discussões levadas a cabo acerca da necessidade de se estabelecer conexões dialogais entre três partes fragmentadas do conhecimento humano: Ciências da Natureza, Filosofia e Ciências Humanas. Diversos eventos, debates, publicações foram concretizadas a esse respeito, mas, ainda assim, compreendemos que se trata de uma discussão necessária para se aprender a conhecer o tema sob a ótica do que propõem autores como Ubiratan D’Ambrosio, Michel Serres, Edgar Morin, entre outros teóricos que se ocupam do tema.

Authors: Roja Parakapali , Reddy Thummala Sankar , Ibrahim Shaik Mohammed , Lorenzini Giulio
Published: June 2022

The numerical analysis of thermal emission on a magneto-hydrodynamics (MHD) stream of a viscous in-compressible nano-fluid due to an exponentially stretched sheet with warm and mass fluxes frontier conditions in the occurrence of viscous dissipation were examined in this work. Using self-similarity transformation, the controlling PDEs are altered into a set of ODEs, which are after that numerically solved via the shooting procedure and a 4th Runge-Kutta method. On the non-dimensional stream, temperature, nano-particle capacity percent, and confined Nusselt and Sherwood figures, the consequences of many miscellaneous constraints are illustrated. The mathematical values of the friction factor coefficient, as well as confined Nusselt and Sherwood statistics, are computed and examined.

Published: June 2022

Development denotes a society's continuous progress toward a better existence. Using secondary data and the Conflict/Elite theory, the paper argued that the goals of social entrepreneurs and the Nigerian State are linked and aimed at proffering solutions to societal problems. In practice, the interaction between these actors are lopsided which result from mistrust, flawed policy synergy on requisite social services provision and inadequate funding which have undermined successes of social welfare programmes in Nigeria. The paper findings indicate that bad leadership, poor governance and lack of social inclusion in public policy formulation poses challenge to promoting national/social entrepreneurship development and socioeconomic transformation in Nigeria. The paper concludes with the propositions that establishing mutual networking and cooperation between social entrepreneurs and the Nigeria state elites will engender positive impact toward the implementation of policies that target the people and engender poverty reduction, create employment opportunities and bridge income inequalities.

Authors: Fonna Azkar , Adam Muhammad , Putra Teuku Roli Ilhamsyah
Published: June 2022

This study aims to test the effect of Perceived Retail Service Quality (SQ), Emotional Value, and image on customer loyalty at public gas stations (SPBU) in Banda Aceh, with customer satisfaction as an intervening variable. The researcher used a simple random sampling technique and determined the number of representative samples by using the formula for the number of indicators multiplied by 10 so that a sample of 250 people was obtained. Data were collected by distributing questionnaires. The research model was analyzed using SEMAMOS. The results prove that Perceived Retail SQ affects Satisfaction, Emotional Value affects Satisfaction, Image affects Satisfaction, Perceived Retail SQ affects Loyalty, Emotional Value affects Loyalty, Image affects Loyalty, Satisfaction affects Loyalty, Satisfaction partially mediates the Perceived Retail SQ effect on Loyalty, Satisfaction partially mediates the Emotional Value effect on Loyalty, and Satisfaction partially mediates the Image effect on Loyalty. This finding means that the model of increasing Customer Loyalty at the Banda Aceh public gas stations is a function of increasing Perceived Retail SQ, increasing Emotional Value, strengthening image, and increasing customer satisfaction.
Comparing the Orthographic and Phonological Vocabulary Knowledge of Japanese EFL University Students
Authors: Jones Craig
Published: June 2022

Reading and listening are both receptive skills. The goal of this study was to investigate whether the participating EFL learners’ vocabulary knowledge was equal in both receptive skills. It is hoped that the study will highlight the importance of presenting and assessing vocabulary in both written and audio form. The participants were 136 university students from central Japan. The participants were presented with the same task in written and audio form. The task used was the X-Lex Vocabulary Test (Meara & Milton, 2003). X-Lex is a Yes/No test that assesses knowledge of the most frequent 5000 words in English. The participant’s results in both versions of the test were compared. A paired samples t-test showed that the participants’ listening vocabulary size was significantly smaller than their orthographic size. The pseudo-word analyses also produced some interesting results demonstrating that the participants’ receptive vocabulary knowledge was imbalanced. During the listening task the participants falsely selected 356 pseudo-words. However, during the reading version only 109 pseudo-words were selected. An independent t-test revealed that the difference was significant. The vocabulary size and pseudo-word analysis both show that the participants’ ability to identify vocabulary was inferior during the listening task.

本研究の目的は，いずれも受容技能であるリーディングとリスニングにおいて，EFL学習者の受容語彙知識が同等かどうかを明らかにすることであった。実験参加者である日本の中部地方の大学生136名に，文字と音声で同じタスクを提示した。そのタスクとはX-Lex Vocabulary Test (Meara & Milton, 2003) であり，英語の最も頻度の高い5000語に焦点を当て，平均的な語彙サイズを明らかにするものである。参加者は，文字もしくは音声提示された語を知っているかどうかをYes/No形式で答えるよう求められた。本研究では，参加者それぞれの両バージョンのテスト結果を比較した。Yes/Noテストの妥当性は当て推量によって影響を受けるが，これに対抗するためX-Lexには疑似語の項目が含まれていることから，両バージョンのテストの疑似語への反応数も分析した。（対応ありの）t検定結果から，参加者のリスニングにおける語彙サイズが，リーディングにおけるものよりも著しく低いことが明らかになった。また疑似語の分析からも，参加者の受容語彙知識に偏りがあることを示す興味深い結果が得られた。リスニングタスクにおいて，参加者は440個の疑似語を誤って既知語と選択していたが，リーディングタスクでは，129個の疑似語しか選択されなかった。このように語彙サイズと疑似語の分析結果から，参加者の語彙認識力が，リスニングタスクにおいてより劣ることが示された。
Memories people no longer believe in can still affect them in helpful and harmful ways
Authors: Burnell Ryan , Nash Robert A. , Umanath Sharda , Garry Maryanne
Published: June 2022

People can come to “remember” experiences they never had, and these false memories—much like memories for real experiences—can serve a variety of helpful and harmful functions. Sometimes, though, people realize one of their memories is false, and retract their belief in it. These “retracted memories” continue to have many of the same phenomenological characteristics as their believed memories. But can they also continue to serve functions? Across four experiments, we asked subjects to rate the extent to which their retracted memories serve helpful and harmful functions and compared these functions with those served by “genuine” autobiographical memories. People rated their retracted memories as serving both helpful and harmful functions, much like their genuine memories. In addition, we found only weak relationships between people’s belief in their memories and the extent to which those memories served perceived functions. These results suggest memories can serve functions even in the absence of belief and highlight the potential for false memories to affect people’s thinking and behavior even after people have retracted them.
Chatbot Language - crowdsource perceptions and reactions to dialogue systems to inform dialogue design decisions
Authors: Popp Birgit , Lalone Philip , Leschanowsky Anna
Published: June 2022

Conversational User Interfaces (CUI) are widely used, with about 1.8 billion users worldwide in 2020. For designing and building CUI, dialogue designers have to decide on how the CUI communicates with users and what dialogue strategies to pursue (e.g. reactive vs. proactive). Dialogue strategies can be evaluated in user tests by comparing user perceptions and reactions to different dialogue strategies. Simulating CUI and running them online, for example on crowdsourcing websites, is an attractive avenue to collecting user perceptions and reactions, as they can be gathered time- and cost-effectively. However, developing and deploying a CUI on a crowd sourcing platform can be laborious and requires technical proficiency from researchers. We present Chatbot Language (CBL) as a framework to quickly develop and deploy CUI on crowd sourcing platforms, without requiring a technical background. CBL is a library with specialized CUI functionality, which is based on the high-level language JavaScript. In addition, CBL provides scripts that use the API of the crowd sourcing platform Mechanical Turk (MT) in order to (a) create MT Human Intelligence Tasks (HITs) and (b) retrieve the results of those HITs. We used CBL to run experiments on MT and present a sample workflow as well as an example experiment. CBL is freely available and we discuss how CBL can be used now and may be further developed in the future.
Supervised machine learning aided behavior classification in pigeons
Authors: Wittek Neslihan , Wittek Kevin , Keibel Christopher , Güntürkün Onur
Published: June 2022

Manual behavioral observations have been applied in both environment and laboratory experiments in order to analyze and quantify animal movement and behavior. Although these observations contributed tremendously to ecological and neuroscientific disciplines, there have been challenges and disadvantages following in their footsteps. They are not only time-consuming, labor-intensive, and error-prone but they can also be subjective, which induces further difficulties in reproducing the results. Therefore, there is an ongoing endeavor towards automated behavioral analysis, which has also paved the way for open-source software approaches. Even though these approaches theoretically can be applied to different animal groups, the current applications are mostly focused on mammals, especially rodents. However, extending those applications to other vertebrates, such as birds, is advisable not only for extending species-specific knowledge but also for contributing to the larger evolutionary picture and the role of behavior within. Here we present an open-source software package as a possible initiation of bird behavior classification. It can analyze pose-estimation data generated by established deep-learning-based pose-estimation tools such as DeepLabCut for building supervised machine learning predictive classifiers for pigeon behaviors, which can be broadened to support other bird species as well. We show that by training different machine learning and deep learning architectures using multivariate time series data as input, an F1 score of 0.874 can be achieved for a set of seven distinct behaviors. In addition, an algorithm for further tuning the bias of the predictions towards either precision or recall is introduced, which allows tailoring the classifier to specific needs.
Kafka’nın Ein Landarzt Adlı Öyküsünün Ara Dilden Çeviri Bağlamında Karşılaştırmalı Analizi
Authors: SARIŞIK Derya
Published: June 2022

Ara dilden çeviri daha önce çevirisi yapılmış bir metnin yeniden başka bir hedef dile çeviri için kaynak metin görevi görmesidir; kısaca çevirinin çevirisidir. Ara dilden çeviri hem birbirine uzak diller ve kültürler arasında yazınsal iletişimi sağlamada hem de dünya klasiklerinin kabul görmesinde önemli bir yere sahiptir. Ayrıca kaynak metne ulaşılamaması ya da kaynak metnin zarar görmesi durumunda bu çeviri türünden faydalanılmaktadır. Ne var ki çeviride oluşabilecek kayıplar açısından ara dilden çeviri doğrudan çeviriye kıyasla iki kat risk taşıdığı için olumsuz bir çağrışımı da söz konusudur. Bu çalışmada Kafka’nın Ein Landarzt adlı öyküsü ara dilden çeviri bağlamında uygulamalı örnek düzleminde karşılaştırmalı olarak incelenmiştir. İlgili öykünün Mehmet Harmancı tarafından aracı bir dil kullanılarak gerçekleştirildiği belirlenen Türkçe çevirisi, Willa ve Edwin Muir çifti tarafından yapılan İngilizce çevirisi ve Kamuran Şipal tarafından yapılan doğrudan çeviri betimsel çeviri araştırmaları ışığında analiz edilmiştir. İncelemede çeviri hatalarını bulmaktan ziyade ara dilden çevirinin etkisine odaklanılmıştır. Bu noktada çevirilerdeki farklı yorumlamaların ve söyleyişlerin ele alınan kaynak metinden mi yoksa çevirmen kararlarından mı kaynaklandığı sorgulanmıştır. Eser analizlerinde özellikle Gideon Toury tarafından geliştirilen “Betimleyici Çeviri Araştırmaları” yönteminden ve çeviri normlarından faydalanılmıştır. Bununla birlikte çoğulcu bir yaklaşım izlenmeye çalışılarak Eugene Albert Nida’nın “eşdeğer etki” kavramına dair görüşleri de göz önünde bulundurulmuştur.

Published: June 2022

Studies were carried out on the influence of the hydrological and hydrochemical regime on the species diversity and biological parameters of goby fish in the western part of the North Caspian in 2016-2018. It is shown that the species composition in these years was represented by 9 species, with a predominance of sand goby and bighead goby and with the increase in sea salinity, stenohaline fish began to appear: gray whip goby and Khvalyn goby, the number of the latter in catches increased in 2018 compared to 2017 by 16.8 times. The number and biomass of gobies in 2018 increased by 4 times compared to previous years and amounted to 2384 million copies, 16.807 thousand. t., respectively, as well as the improvement of their biological parameters, indicate the favorable state of the population, and hence the food supply for anadromous fish, in particular, sturgeon, semi-anadromous species, marine migratory herring.
One of the effective ways to determine the catchability coefficients of fry seines
Authors: Matkovsky Andrey
Published: June 2022

One of the methods of conducting experimental work to determine the coefficient of catchability of juvenile seines in relation to different-sized whitefish juveniles is considered. The method is based on fencing off part of the water area with a business curtain. The positive aspects of the method are associated with the exclusion of the influence of emigration, immigration and natural mortality of fish, as well as with the possibility of using several methods for calculating the catch coefficient (accumulated catch, catch per effort, Leslie). The comparability of the results obtained by different methods is noted, improvement of calculations by the Leslie method taking into account natural mortality is proposed. The relatively high sensitivity of the Leslie method to the degree of overgrowth of the experimental site was revealed. In general, the catch coefficient decreases with the growth of juveniles, a decrease in the size of the fishing gear and an increase in the presence of macrophytes. It has been established that whitefish juveniles prefer to stay clean of aquatic vegetation with growth.

Published: June 2022

Star-point reactors are grounding devices installed in HVDC stations between the converter transformer secondary side and AC side of converter arms to provide a reference to ground. Such reactors are used as high-impedance grounding on the converter side of power transformers, providing high impedance path for the fundamental harmonic (i.e. 50 or 60 Hz) and a low impedance path for DC current, eliminating DC current flowing through the transformer windings. Temperature rise and DC current capability tests of 420 kV star-point reactor are presented in this paper. The purpose of temperature rise test is to verify that temperatures that can damage the insulation of star-point reactor will not be reached with the specified service conditions. The temperature rise test was carried out according to the requirements of the IEC 61869-3 standard and client’s request which included simultaneous application of fundamental, 3rd harmonic voltage and DC excitation. The inclusion of 3rd harmonic excitation of an amplitude up to 15% simulates voltage harmonic distortion which may appear in the power system at the location of star-point reactor installation. Prior to temperature rise test, DC current capability test was performed. The goal of this test is to determine the value of DC current at which the saturation point is reached. DC current is injected through star-point reactor while AC voltage is applied. Two different cases are considered regarding AC voltage: test with fundamental voltage harmonic and test with fundamental voltage harmonic with superimposed third voltage harmonic. Test circuit is proposed which is suitable for generation of complex voltages composed of fundamental harmonic and superimposed third harmonic with amplitudes up to 15% of the applied fundamental harmonic. The proposed test circuit was also used during the temperature rise test and it is applicable for testing of HV equipment with rated voltage up to 420 kV.

Published: June 2022

This article is concerned with the impact of corporate digitalization on the corporate sustainability performance and with barriers and supportive institutional frameworks for corporate digital technology adaptation. Collected from big data sets such as the Digital Economy and Society Index (DESI) country reports and the Global Innovation Index (GII), our study draws on data from 29 European countries. A series of multiple linear regressions was run to select the most relevant predictors of corporate digital technology adaptation. The results suggest that Rule of Law, Government Effectiveness and Ease of Starting a Business are the institutional framework pillars that best predict corporate digital technology adaptation levels. Our findings further show that high levels of corporate digital technology adaptation occur where institutional frameworks are well-integrated across several social domains (economy, politics, legal system, etc.). We conclude by highlighting implications for the design of digital policies aiming at a strategic integration of digital technology adaptation and corporate sustainability.

Published: June 2022

INTRODUCTION: Healthcare-associated infections (HAIs) are frequently found in patients worldwide each year with varying rates. In November 2021, there were 23 incidents of nosocomial infection at a General Hospital in Banda Aceh. Of these incidents, eight occurred in the surgical inpatient room. Nurses have a significant role in reducing the number of hospital infections. Nurses must utilize the knowledge and skills of nursing practice to facilitate patient recovery while minimizing infection-related complications in patients.
AIM: This clinical observation aims to identify the practice of 5 moments of hand hygiene in the surgical inpatient ward, General Hospital Banda Aceh.
METHODS: This clinical observation aims to identify the practice of 5 moments of hand hygiene in the surgical inpatient ward, General Hospital Banda Aceh. This clinical observation with a population of 26 nurses. A sample of 16 nurses was obtained through the incidental sampling method. The tool used to collect data is in the form of a hand hygiene observation sheet that was observed at five moments according to World Health Organization (WHO) standards.
RESULTS: The five-moment hand hygiene showed that the nurse hand hygiene practice was 68.7%-100%. The sequent percentage values ​​of practicing hand hygiene are: 68.7% of nurses do not apply hand hygiene before contact with patients; 75% of nurses did not apply hand hygiene before aseptic action; 75% of nurses apply hand hygiene after contact with the patient's environment; 93.7% of nurses apply hand hygiene after contact with patients, and 100% of nurses apply hand hygiene after being exposed to the patient's body fluids. Finally, only four respondents (25%) thoroughly applied five hand hygiene moments.
CONCLUSIONS: The leadership role of the head nurse is needed to optimize the practicing of hand hygiene in the hospital inpatient room, which is shown through role models, continuous supervision, and evaluation. In addition, good infrastructure is also needed to support these activities.

Introduction: Experimental autoimmune (allergic) encephalomyelitis (EAE) induced by intradermal injection of ho­mogenate of the brain, spinal cord and peripheral nerve with Freund’s stimulator, refers to a true autoimmune disease of the nervous system.

Materials and methods: Experimental studies were conducted on white nonlinear rats. To induce experimental aller­gic encephalomyelitis (EAE), homologous brain homogenates was used, which leads among other drugs (homologous, heterogeneous brain and spinal cord homogenates) by encephalitogenity. The connective tissue of the animal’s tail base was injected with a mixture of encephalitogenic suspension of 0.1 ml per 100 g of the body weight.

Results and discussion: According to the results, in the rats, there was weight loss, and the abnormal neurological symptoms were found on an average of 10–12th days. Our experimental studies on the formation of EAE were con­firmed morphologically by electron microscopy.

Conclusion: Thus, the use of this technique allowed us to obtain a simulated pathologic condition of multiple sclerosis in the form of experimental allergic encephalomyelitis and can be used in future studies to identify appropriate laws, the extent and nature of changes in the immune and nervous systems of the body when inducing experimental pathological conditions.
Study of the operational conditions for ethyl esters production using residual frying oil and KF/clay catalyst in a continuous system
Authors: Zempulski D.A. , Postaue N. , Stevanato N. , Alves H.J. , Silva C.
Published: June 2022

The transesterification of residual frying oil (RFO) with pressurized ethanol was carried out in a continuous reactor containing KF/clay as a heterogeneous catalyst. In the experiments, different oil:ethanol mass ratios were evaluated at 275 and 300 ºC and 20 MPa. In the sequence, the operational stability of the catalyst was evaluated for 8 hours, as well as the conduct of the reaction in two steps (testing new and recycled catalyst). An esters yield of ~90% was achieve at 275 ºC, for15 min and at 1:1.5 oil:ethanol mass ratio. Under these conditions, the catalyst provided a stable yield in the first 3 hours of operation, and a total decrease of 29% after 8 hours. This result can be attributed mainly to the leaching of the K+ cations for the reactions in which the catalyst was exposed to long operating times. The two-step reaction served to increase the RFO conversion to esters, with low thermal decomposition.
Recent advances in plant-based fat formulation as substitute for lard
Authors: Marikkar J.M.N. , Yanty N.A.M. , Musthafa S. , Miskandhar M.S.
Published: June 2022

Lard is one of the main animal fats used as shortening and frying medium. Religious prohibitions and negative health perceptions regarding animal fats have caused concerns about the consumption of lard among communities living around the world. Various research efforts have been made in the past to formulate plant-based fats and shortenings as substitutes for the exclusion of lard from food. This would eventually help countries to regularize food formulations according to their religious compliance. As the existence of a single plant fat as substitute for lard has not been discovered from nature, researchers attempted to study the possibility of mixing native fats and oils such as enkabang fat, canola oil, guava oil, palm oil, palm stearin, soybean oil and cocoa butter as raw materials. The compatibility of the formulated plant-based fat substitute for lard was assessed in terms of chemical composition and thermo-physical properties. The formulated plant-based shortenings and lard shortening were simply plastic fats based on their consistency value and existence of β’ and β-form polymorphs of which the β’ -form was dominant. The functional properties of formulated plant-based shortenings and lard were also compared in the formulation of cookies. Although a substantial amount of work has been done over the past decade, there was hardly any discussion on the pros and cons of the approaches used for raw material selection and the criteria adopted in the assessment of the formulated products. Hence, this review intended to bring an update of the progress of studies with regard to these two aspects.

Very large-scale integration (VLSI) circuits operating at ultra-low power are currently acquiring more attention from the research group and the industries too. Recently, the performance of many applications depends on the size and energy consumption of sensor nodes. The energy efficient sensor nodes with reduced size are much preferred among applications such as wireless sensor networks, pollution and plant monitoring. The biggest challenge faced by the VLSI designers in present day life is designing a product of new generation which operates on minimum possible power. Power consideration is the eventual design criteria in different real-life applications like pacemakers etc. Phase Locked Loop is a framework that produces an output which is in phase with the input signal. In Phase Locked Loop (PLL), the focus is at the input signal’s phase with its output oscillator signal’s phase and thus modifies the recurrence frequency of the Voltage Controlled Oscillator (VCO) for phase co-ordination. The output signal from the Phase Frequency Detector is utilized to control the oscillator in a feedback circle also. As an operational gadget, the PLL has wide scope of utilization in media transmission, PCs and electronic applications. In this paper, designing and analysis of PLL with numerous outputs has been proposed to be implemented by changing the closed loop frequency control framework PLL blocks. As such, highly effective, low power, ideal area chip can be used for PLL with four various yields as PLL 8x, PLL 4x, PLL 2x and PLL 1x with different frequencies separately. Likewise, it is planned to utilize multi-threshold or sleep transistors to minimize the leakage current in the circuit. Further, the execution or performance verification of various parameters of PLL are done to acquire negligible power. Direct toolbox YALMIP is used as programming solver as an optimization tool. In addition to this, another method of Non- dominated sorting genetic algorithm (NSGA-II) Correlation for optimization is also introduced between both the strategies to find the best outcomes.

Automatic detection of heartbeat is critical for early cardiovascular disease prevention and diagnosis. Traditional feature methodologies based on expert knowledge cannot abstract and represent multidimensional and multi-view information. Hence traditional research on heartbeat detection pattern recognition cannot produce adequate results. The proposed method in this research used Dispersion Entropy (DisEn) on Multidistance Signal Level Difference (MSLD) for feature extraction and Support Vector Machine (SVM) method for classifying the ECG signals. DisEn generates 20 DE values as feature vectors for each MSLD signal with a distance D of 1 to 20. The datasets used in this research were obtained from the MIT-BIH Arrhythmia database of ECG signals that consist of forty-five patients was captured using 200 [adu/mV] amplification and a sampling frequency of 360 Hz. The experiments result using 5-fold cross-validation revealed that at distance D= 1-15 had the highest accuracy of 91% to classify the ECG data into Normal Sinus Rhythm (NSR), Left Bundle Branch Block (LBBB), and Atrial Fibrillation (AFIB) from the MIT-BIH Arrhythmias database.

This paper aims to generate electricity, by decreasing fossil fuels consumption and conserving electricity for further use.  In this project, the method is to produce pollution-free electricity using the technique i.e. piezoelectric effect technique. By applying mechanical stress electric charge is generated known as the piezoelectric effect.  A sufficient amount of energy is produced as it can reduce the damage of pollution caused by power plants. So to make the use of moving vehicles on road, power generated helps the environment last longer.  Different shape, proof mass geometries are analyzed and plotted a graph between frequency versus voltage and electrical energy. Among them, it is identified that stacked cylindrical block has a good Voltage of 2.04mV (milliVolts = 10-3V) and Energy of 21.2fJ (femtoJoule = 10-15J).

Abstract— Data Sources: Articles for this paper were sourced from PubMed and Google Scholar databases. Data Extraction: Human studies published in English from 2015 to 2021 were included. Two reviewers initially assessed abstracts of 958 papers and 192 papers were selected for future assessments. After a full review, 38 articles were selected. Results: Dietary salt is a high-risk factor for Gastric Cancer (GC) while red meat and a high-fat diet increase the risk. Alcohol intake is only a risk if consumed heavily.

Conclusion: Dairy foods, vitamin C, smoked food, rich food, and Helicobacter pylori are included in the etiology of GC. So are fresh fruits, vegetables, and specific refined grains. Salt, fats, spicy foods, alcohol, red meat, and pepper increase the risk. Knowing cancer patients' nutrition problems would help intervention measures be taken to remedy the situation.

Previous studies report that the COVID-19 pandemic has a negative effect on the psychological wellbeing of medical students. We aimed to determine the psychological impact of COVID-19 and its associated factors among a cohort of Sri Lankan medical students, using online versions of a demographic questionnaire and the validated Sinhala and Tamil versions of the DASS-21. Of the 418 students, majority were females, aged between 20-25 years. In the study group, 40 (9.6%), 105 (25.1%) and 7 (1.6%) of participants scored above the cut-offs for the depression, anxiety and stress subscales of the DASS-21 respectively. The COVID-19 pandemic appears to be associated with a negative impact as measured by the DASS-21 scale among this group of medical students.

Authors: Sadiki Marubini C. , Kibirige Israel
Published: June 2022

Background: Society places people with physical disabilities acquired during adulthood in disadvantaged positions, especially when they cannot participate in activities like their non-disabled counterparts. The situation can be worse for individuals who acquire disabilities during adulthood, where they have to learn to cope with the adulthood-acquired physical disabilities.Objectives: This study aimed to identify the types of physical disabilities acquired during adulthood and their causes and explore how participants defined their disabilities and the coping strategies they used.Methods: The study used a phenomenological research design. Five adults (three women, two men) with adulthood-acquired disabilities were purposefully selected from a rural area in Limpopo, South Africa. Data were collected using semi-structured interviews. Thematic analysis was used to generate themes about coping strategies study participants used.Results: The results show four types of adulthood-acquired disabilities amongst the participants: visual impairment, paraplegia, weakened muscles which led to bilateral amputation, loss of function on both hands and legs. Participants’ meanings of their physical adulthood-acquired disabilities ranged from a punishment, pain, not a bother, black magic, to results of doing wrong things to someone. In coming to terms with their adulthood-acquired disabilities, participants used problem- and emotion-focused strategies. Four themes from the participants’ responses were spiritual support, social support, substance dependency, access to health and rehabilitation services.Conclusion: The study contributes to understanding the experiences of individuals who acquired disabilities in adulthood, how they define their disabilities and the divergent coping strategies they use. This study established that participants used problem-focused, positive emotion-focused and negative emotion-focused coping strategies.

Authors: Dawood Yousif F.
Published: June 2022

Background: The cornea is the anterior transparent part of the eye. In addition to its optical and refractive function, it is an important protective structure.Aim: The aim of this study was to assess corneal endothelium (counts, morphology and structure) as well as corneal thickness of Type 2 diabetic participants.Setting: This is a hospital-based case–control study and was carried out at Ibn Al Haitham tertiary eye hospital in Baghdad, Iraq.Methods: The sample size was 240 eyes of 120 diabetic participants and 120 healthy participants. Non-contact specular microscopy was utilised to evaluate corneal endothelial cells, including endothelial cell density (ECD), coefficient of variation in cell area (CV), hexagonality (HEX) of cells as well as central corneal thickness (CCT).Results: The ECD was lower in the diabetic corneas (2584.87 ± 259.15 cell/mm2) compared with the healthy corneas (2717.56 ± 289.67 cell/mm2) (p = 0.017, statistically significant). Coefficient of variance (CV) was greater in the diabetic group (40.8 ± 4.17) as opposed to the group with healthy corneas (37.3 ± 2.89) (p = 0.019, statistically significant). The corneas of the diabetic group showed lower hexagonality (44.36% ± 9.87%) compared with the healthy corneas (59.35% ± 9.67%) (p  0.001, statistically significant). Furthermore, the corneas of the diabetic group had greater central thickness (581.1 ± 32.4 µm) when compared with the control group (511.8 ± 29.8 µm), (p  0.001, statistically significant). No correlation was found between the severity level of diabetic retinopathy and corneal endothelial pathological alterations.Conclusion: Long-term poorly controlled glycaemia has a remarkable impact on corneal endothelium (counts, morphology and structure) as well as corneal thickness.

Islamic values are among the topics that are considered by people in an Islamic society in human and organisational life and paying attention to them can have positive consequences for the individual and the organisation. The purpose of this study is to investigate the effect of Islamic values on citizenship behaviours of Muslim citizens. The research is applied in terms of purpose and descriptive-survey in terms of nature and method. The statistical population of this research includes 2600 Muslim employees of 45 manufacturing Indonesian organisations in 2021. The sample size was estimated to be 335 by simple random sampling. The data collection tool of this study is a questionnaire. The validity of questionnaire was confirmed by confirmatory factor analysis and reliability by Cronbach’s alpha coefficient; further, data analysis was performed using linear structural relationships (LISREL) software. The results of structural equations modeling showed that Islamic values have a positive and significant effect on citizenship behaviours of Muslim citizens (p = 0.78; T-Value= 8.62).Contribution: The results showed that paying attention to Islamic values in the organisation contributes to citizenship behaviours of people. Therefore, it is suggested that Islamic values be the basis of staff activities and employees who are more committed to these values in the organisation should be encouraged by the management of organisations.
