Flame retardant characteristics of polymerized dopamine hydrochloride coated jute fabric and jute fabric composites
Authors: Öktem Mehmet , Aydaş Bahadir
Published: August 2021

In this paper, fire resistance of natural fabrics and their composites were experimentally investigated. Special interest was given to use bio based materials such as lignin, chlorophosphates, levulinic acid and cardanol in order to exploit their capability to be utilized as flame retardants. Dopamine hydrochloride was polymerized to polydopamine (PDA) and coated to jute fabric surface. Scanning electron microscope (SEM) and thermogravimetric analysis (TGA)/derivative thermogravimetric (DTG) analyses were performed to examine surface morphology and effect of PDA to degradation behaviour of jute fabrics. Real fire behaviour of non-coated and coated fabrics was observed with torch burn test. UL-94 horizontal flame propagation test was also utilized for composite samples. Limiting oxygen index (LOI) testing that measures the minimum amount of oxygen required for combustion, was carried out for assessing the ability of the composite samples for their ability against flammability. PDA was seamlessly coated on the surface of the jute fabrics with its surface-active feature without damaging the structure of the fabric as observed in the SEM images. With the support of this coating on the fabric surface, the increase of the decomposition temperature of the material can be clearly seen in TGA/DTG analyses and torch burn test showed the increase in the ignition time. UL-94 horizontal testing resulted in decrease in flame propagation rate of PDA coated composite samples. In addition to this, when the mass loss rates after combustion were examined, it was seen that there is a decrease in mass loss in the coated fabrics. Jute fabrics, a type of natural fabric, can be efficiently coated with PDA, and the fire retardant property of the PDA coating on natural fabrics has been clearly demonstrated.

Authors: Ralevic Lidija , Tomasevic Biljana , Trivic Dragica
Published: August 2021

In the last decades online communication has become an important part of the realization of the educational process. In the conditions caused by the Covid-19 pandemic it has become particularly significant since in most cases it was necessary to switch to some forms of online teaching-learning. This paper presents the results of a research study conducted as a pedagogical experiment with parallel groups. The aim of this research study was to compare the effects of the application of internet pages for independent online asynchronous learning outside the school environment (group A) and face-to-face learning realized by a teacher at school (group B). The content of the internet pages was created in order to enable the acquisition of the concepts of solutions and dissolution. The effects of the approaches applied were studied based on the student achievement in a post-test (immediately upon learning about the concepts of solutions and dissolution) and in a delayed post-test (a year after the acquisition of these concepts). The participants in this research study were 187 primary school students, who participated in the pedagogical experiment when they were in the seventh grade, while they were in the eighth grade when they did the delayed post-test. The results showed that there was not a statistically significant difference between the overall achievements of the students who learnt about the concepts of solutions and dissolution by independent asynchronous online learning and face-to-face learning at school. This implies that the similar results can be achieved with asynchronous online learning as with face-to-face learning when the conditions do not allow school-based education.

Authors: Gaivoronskaya Yana V. , Dremliuga Roman I. , Mamychev Alexey Y. , Miroshnichenko Olga I.
Published: August 2021

The research objective of the paper is to generalize the ethical problems associated with the development and implementation of autonomous robotic technologies (autonomous robotic devices, ARD) in the civil and military spheres. Unresolved ethical problems hinder the development of legal regulation of new technologies. The authors propose a typology of ethical problems of digitalization for the purpose of creating legal regulation concerning the use of artificial intelligence (AI) and other technologies. Depending on the scope of social relations covered and the forms of regulation proposed, the authors identified four groups of ethical problems of global digitalization, which are considered in the paper: philosophical, humanitarian, socio-ethical, and ethical-legal problems. It is concluded that the legitimacy of managerial decisions that endow robotic technologies with the potential to make decisions in the civil and military spheres should be determined in terms of ethical principles of regulating such relations.

Authors: Payadnya I Putu Ade Andre , Wibawa Kadek Adi
Published: August 2021

The purpose of this study was to analyze students' metaphorical thinking skills in the statistic method subject during COVID-19 Pandemic using three stages of metaphorical thinking. This research was conducted from March to May 2020. Subjects in this study were 11 students of class IIB of Mathematics Education Study Program Mahasaraswati University Denpasar. This study uses descriptive analysis techniques. Data collected through tests, interviews, observations, and documentation. The results showed that students’ metaphorical thinking skills in online learning during COVID-19 Pandemic was still very low where only 20% of students answered correctly at the grounding metaphors stage, 25% at the linking metaphors stage, and only 25% at the redefinitional metaphors stage. Students tend to be confused when required to associate statistical concepts with everyday phenomena and discover the characteristics of the concepts. Online learning due to COVID-19 Pandemic also causes the suit of students to do group discussion as well as the decrease in student motivation primarily in solving metaphorical thinking questions. Some solutions that can be taken to overcome this problem are: 1) Using interactive learning, 2) Using Project-Based learning (PBL), 3) Discussing current trends in learning, 4) Demonstrating assertiveness, and establishing learning rules.

Tax Fairness in a Developing Country: Perceptions of Malaysian Tax Agents
Authors:   Kolej Universiti Poly Tech MARA, Binti Azemi Azwanis
Published: August 2021

Tax fairness has been used as one of the important determinants for tax compliance. Good perception of tax fairness would encourage taxpayers to comply with tax laws to avoid any unreported and unpaid revenue to the government. Individual taxpayers are required to pay income tax, and they may engage with tax agents for their tax computation. This situation motivates this study to look into further dimensions of tax fairness by looking at tax agents’ perception as they are important people to consult and give advice on tax matters. The main objective of this study is to propose the dimensions of individual tax fairness based on tax agents’ perceptions in Malaysia, and secondly, to study prior literature and classify the dimensions of individual tax fairness that have used a similar measurement used in Gerbing’s study. Survey questionnaires were distributed at two tax conferences held in Kuala Lumpur, and the final data of 196 responses were analysed by exploratory factor analysis (EFA). The results indicated that tax agents identified six dimensions of tax fairness, and regardless of developed or developing countries, the number of dimensions of tax fairness could be identified , depending on the level of individuals’ tax practice and knowledge. These results are expected to provide implications either in the theory and practice of tax fairness dimensions in Malaysia. KEYWORDS: Tax fairness’ dimensions, tax agents, exploratory factor analysis, income taxes.

Published: August 2021

"This paper aims to examine the determinants of Islamic and conventional banking profitability in Asian countries. We estimated an econometric model using the Generalized Method of Moments (GMM) from 2009 to 2013 based on 162 conventional banks and 65 Islamic banks operating in a dual banking system. This paper extends prior literature by examining the profitability of Islamic banks and conventional banks using the more comprehensive determinants, especially in Asian countries where studies are observably limited. The results show that the factors influencing the profitability of Islamic and conventional banks are different. The profitability of Islamic banks is significantly affected by the size, management efficiency, inflation, market concentration, the rule of law and monetary freedom. For conventional banks, the key determinants include capital, size, credit risk, management efficiency, monetary freedom and economic growth. The findings provide policy implications for enhancing the profitability in a dual banking system. KEYWORDS: Islamic banks; conventional banks; return on assets; Asian countries; GMM"
Company-specific Characteristics and Market-driven Fixed Asset Revaluation in an Emerging Asian Economy
Authors:   ", Rahman Md. Tahidur ,   Bangladesh Army International  University of Science and Technology, Bangladesh"
Published: August 2021

"This study aimed to explore the company-specific and market factors driving fixed asset revaluation (FAR) in an emerging economy. Our research was based on a sample of 142 companies listed on the Dhaka Stock Exchange (DSE) – the main bourse of Bangladesh. The binary logistic regression model was the main instrument used to measure the significance level of variables and test the hypotheses. The study found that market conditions, profitability, nationality, debt-to-asset ratio, fixed assets intensity, and company size could influence FAR decisions significantly. But, company age and current ratio have failed FAR decisions insignificantly. Since there are suspicions about the creative practice of FAR, users need to be cautious when explaining and utilizing the information communicated via financial statements of companies that revalued their assets. Besides, regulators should strictly enforce the laws to avoid selective disclosures, and companies should fully disclose market-sensitive information so that corporate stakeholders promptly receive FAR-related disclosures. This paper could serve a large assortment of stakeholders interested in knowing the drivers behind and effects of FAR. Inclusion and the explanation of three new factors, corporate nationality, age, and market condition, could be an extension of the existing FAR literature. Keywords: Fixed asset revaluation, Fair value, IAS 16, Stock market crash, PP&E"

The Indus Delta Between Past and Future: Precarious Livelihoods and Neoliberal Imaginaries in a Parched Coastal Belt
Authors: Karrar Hasan
Published: August 2021

The Indus delta, at the terminus of the Indus river system, is presently home to 300,000 residents. Over the last century, upriver hydrology has reduced the flow of water through the river. The result is salination and seawater incursion that has led to the loss of arable land and with it, agriculture as a sustainable livelihood. This has created precarious livelihoods, as people are forced either into the informal fishing sector, or to migrate; this is a departure from earlier times when agriculture was the primary vocation, and forests covered large swathes of the region. I also discuss future plans for port development in the delta that is constitutive of a neoliberal developmentalist imaginary. This vision, in which a future Pakistan will be connected to markets in Asia through its ports, has been propagated for decades, and most recently as a consequence of China’s ongoing investment regime in Pakistan. In the conclusion, I reflect on the paradox of fixation on fantastical futures while the population is caught up in an uncertain present.

Barokah Building Shop (TB. Barokah) located in Singosari, Malang, East Java is one of the shops that sells building materials. Some of the items being sold are white cement and black cement. The number of cement sales every month is very diverse and fluctuating. Black cement occupies a very high number compared to black cement on the sales chart every month. Likewise with the black cement from the Bosowa brand, white cement from the Gresik brand and the Tiga Roda brand, although demand is small, there is still a movement in the number of sales. The fluctuating amount of demand made the amount of product inventory prepared uncertain, which was influenced by the number of types and brands, so that the product inventory management had difficulty in supplying it. This study aims to predict the amount of cement sold in the following month, as well as to determine the performance between the two double exponential smoothing (DES) methods and the simple moving average (SMA) to forecast cement sales results in TB. Barokah. The SMA method is able and can perform forecasts with stable/constant demand or sales data. Meanwhile, the DES method is able and can provide values to the stratified weights with up to date data. DES is capable of forecasting cement sales each month with an average percentange error (PE) of 0.14%, while the SMA is with an average PE value of 1.35%. Based on the test results using data from TB. Barokah found that the most effective method is DES because it has a smaller PE value than the SMA.

Published: August 2021

Background: Healthcare-associated infections (HCAIs) occurring outside of health facilities are underestimated because there are a lack of structured preventive organization and absence of epidemiological surveillance. HCAI prevalence is likely to grow with the increase in patient care outside of health institutions. Aims: To set up a situational analysis of good hygiene practices among private general practitioners (GPs) to better organize HCAI prevention in this sector. Methods: A descriptive cross-sectional study was conducted between November 2017 and March 2018, using a self-administered questionnaire among all GPs in Sousse City, Tunisia. Results: Participation rate was 93.1%. There was a predominance of male GPs (63%), with a sex ratio of 1.7:1. Up-to-date vaccination status was reported by 82 (75.9%) of GPs. Fifty-six (51.3%) GPs used hydroalcoholic solutions, 13 (12.1%) adopted autoclaving, and 106 (98.1%) wore gloves during invasive care. Blood exposure accidents (BEAs) were reported by 38 (35.2%; declared in 26.3% of cases) and were more prevalent in the group aged > 50 years who used significantly more reusable equipment. BEAs were primarily due to needle-stick injuries (86.8%). Conclusion: We identified the priority axes to be considered in organizing HCAI prevention in the private sector, which allows guidance of GPs, avoiding their isolation and compensating for their lack of training and information. This requires willingness and a culture of improving the quality and safety of care in this sector. Committed involvement of several stakeholders at different levels of decision-making in health care is needed.

Los pueblos pobres del mundo siempre parecen llamados a padecer las enfermedades, las guerras, el hambre y la muerte, ante los ojos impávidos de la comunidad internacional. Se siguen creando organismos, instituciones, fundaciones, agrupaciones, de carácter global o nacionales, sin que se observen resultados eficaces de sus gestiones, disminuyendo realmente las enfermedades y los decesos de tantos vulnerables en el planeta. Uno de los flagelos más grandes que tiene la humanidad, han sido y siguen siendo las enfermedades infectocontagiosas, entre ellas, las enfermedades tropicales, cuyo espacio geográfico parece limitado más bien por franjas de miseria que por condiciones climáticas. Son más bien elementos geo históricos los que inciden en la aparición de estas enfermedades, que no solamente climatológicos. Estas patologías se deben a múltiples factores, que han hecho de la Medicina Tropical una ciencia multidisciplinaria con el paso del tiempo, pero, en definitiva, parece que las peores enfermedades infecciosas han sido, indiscutiblemente, la colonización y la pobreza.

In this paper the possibility of snow cover remote sensing from an unmanned aerial vehicle-quadrocopter (UAV) with using a broadband pulse of 1.05 ns duration was investigated on the agricultural field near Minino village, Krasnoyarsk Territory from November 23, 2020 to March 4, 2021. A log-periodic antenna (from 1.36 GHz to 4.89 GHz bandwidth) and a compact vector network analyzer CABAN R60 (LLC Planar, Chelyabinsk) were used to generate, emit and receive broadband pulses. It is shown that both ground-based and remote sensing from the UAV, the time delays between pulses reflected from the air-snow and snow-soil interface linearly depend on the snow water equivalent, measured at the test site. The slope of these linear dependences is determined by the average density of the snow cover. The obtained experimental results show the promising of development of remote sensing technology for radar mapping of the main characteristics of the snow cover from UAV, which can supplement the information support of existing systems used in precision farming.

Un total de 105 profesores de los programas de especialización evaluaron tres áreas de competencia profesional: 1) atributos profesionales generales del residente durante su formación, 2) competencias prácticas (procedimientos quirúrgicos) que los residentes deben realizar al final de su entrenamiento y 3) Actividades Profesionales Confiables (APC) que los residentes deben ejecutar sin supervisión al final de su entrenamiento. Los resultados informan un alto nivel de consenso en el 100 % los atributos profesionales generales y APC, y del 75 % en diferentes procedimientos quirúrgicos. El consenso abre la puerta para el desarrollo de un currículo nacional de la especialidad y tiene implicaciones para la práctica educativa e investigación futura.

Part I of the paper discusses the Americans with Disabilities Act or ADA, its requirements, and various protections for persons who suffer from a recognized disability which impacts their ability to work under certain circumstances and conditions. The context of this study is American higher education. Part II will discuss the obligation of an employer to offer a “reasonable accommodation” of the nature sought by an employee which would permit the employee to continue teaching while otherwise meeting all of the obligations imposed on faculty members under appropriate university policies. Specifically, the research question considered in Part II relates to whether “commuting” is a covered activity under the ADA which would trigger the responsibility of providing the employee with a reasonable accommodation, allowing an employee to teach in the employee’s preferred combination of online and hybrid modalities.

The research aimed to investigate what Turkish experts say sustainable development goals and teaching about achieving these goals. The research has a qualitative design, and the analysis of the interviews consisting of ten questions was made by document and content analysis. Interviews were held with ten academicians, who are experts in their field and have included the topic of sustainable development in their studies. Interview questions consisted of two parts in terms of content, in the upper part only for scientific purposes and for information purposes in consideration of ethical rules, as well as demographic information and the main questions. The main questions are based on determining whether the curriculum is sufficient in terms of the education of sustainable development, as well as identifying students who have gained awareness about this issue and the behaviors that can be expected from students. The interviews lasted an average of twenty-five minutes. The data were analyzed by transcribing the sound recordings. After the analyzes were completed, the codes, categories, and themes related to the questions were determined. As a result, with this study, a needs analysis, which is the first stage of the sustainable development teaching material to be developed within the scope of a large project study, has been made. In line with the results, new acquisitions about sustainable development were developed.

Preeclampsia is a disease that occurs in pregnancy after 20 weeks of gestation with manifestations involving multi organ systems such as pulmonary edema and ventricle dysfunction. Cardiomyopathy is a heart disorder characterized by myocardial dysfunction unrelated to any other previous heart disease. Case: A 31-year-old woman diagnosed with G1P0A0 full-term pregnancy, preeclampsia, pulmonary edema, cardiomyopathy, and fetal distress, who underwent cesarean section. On physical examination, shortness of breath was found in semi-Fowler position. Patient had high blood pressure and global hypokinesis was found on echocardiography results. She was planned for general anesthesia with semi-closed intubation technique and breath controlled. Anesthetic management should optimize the preoxygenation, provide positive pressure ventilation with positive end-expiratory pressure (PEEP), maintain the minimal myocardial depressant effect of drugs, and maintain a normovolemic state. It could improve the good outcomes. Conclusion: Three things that must be considered when starting the induction are oxygenation, fluid status, and selection of drugs that do not make the heart work harder. The combination of fentanyl, midazolam, and sevoflurane is the drug of choice used for induction, because it can minimize the cardiac depressant effect.
Early Post-Acute Myocardial Infarction: Psychosocial and Financial Concerns

Purpose: Acute myocardial infarction (AMI) is a major cardiovascular event that has significant psycho-social-physical and lifestyle consequences. This study assessed the feelings of patients within days following an AMI in a public health institute in Trinidad and Tobago. Results: Of the 150 AMI patients, 134 (89.3%), were included in the study. Sixteen (10.7%) patients were not included due to inadequate information. Among the post-AMI patients, common negative feelings experienced include fear of another heart attack (n = 74, 55.2%), fear of death (n = 40, 29.9%), and fear of the future (n = 29, 21.6%). However, the positive thoughts of the AMI patients predominated: intentions to improve eating habits (n = 97, 73.5%), and increased spirituality (n = 82, 62.1%). Changes in feelings from pre to post AMI were most pronounced for positive feelings such as improved eating habits, regular exercise, and improved goals. In general, among the post-AMI patients, there were no significant associations between age and sex. However, significant associations were found between selected lifestyles variables (exercise, alcohol, eating habits, employment status, hypertension, and obesity) and psychological issues such as fear of another heart attack, improved relationships, or turning to God. Conclusions: Post-AMI patients experienced major psychosocial issues in the early post-AMI period. Though negative feelings were common, most of the patients resolved to make positive lifestyle changes.

Machine Learning-Based Sensitivity of Steel Frames with Highly Imbalanced and High-Dimensional Data
Authors: Koh Hyeyoung , Blum Hannah Beth
Published: August 2021

The machine learning-based feature selection approach is presented to estimate the effect of uncertainties and identify failure modes of structures that incorporate a low failure probability and high-dimensional uncertainties. As structures are designed to have few failures, a dataset classified based on the failure status becomes imbalanced, which poses a challenge for the predictive modeling of machine learning classifiers. Moreover, in order to improve the accuracy and efficiency of the model performance, it is necessary to determine the critical factors and redundant factors, especially for a large feature set. This study benchmarks the novel method for sensitivity analysis by using datasets that exacerbate the problems involved in class imbalance and large input features. This study investigates two planar steel frames with spatially uncorrelated properties between structural members. Geometric and material properties are considered as uncertainties, such as material yield stress, Young's modulus, frame sway, and residual stress. Six feature importance techniques including ANOVA, mRMR, Spearman's rank, impurity-based, permutation, and SHAP are employed to measure the feature importance and identify parameters germane to the prediction of structural failures. Logistic regression and decision tree models are trained on the important feature set, and the predictive performance is evaluated. The use of the feature importance approach for structures with a low probability of failure and a large number of uncertain parameters is validated by showing identical results with the reliability-based sensitivity study and appropriate predictive accuracy.
Ethical considerations in post-GDPR social media based research

Published: August 2021

With the number of social media users being recently estimated to be around 3.96 billion, social media sites present a vast pool of potential participants and data for researchers. Reflecting the growth of this technology and volume of data, data protection laws have been updated across the European Union (EU) and apply to the movement of data in and out of the EU. This article discusses how to approach ethical considerations in light of these new laws and the ethos they represent. We provide this in the context of collecting Twitter data for a pilot study and discuss the considerations in line with legal and ethical guidelines. Our decided approach is offered as an example of the outcome of such considerations. It is clear from this discussion that any approach to ethics, particularly where social media is concerned, requires a reflective and tailored approach.
