English Language Pronunciation Barriers Encountered by the Expatriate Students at King Saud University, Riyadh
Authors: Elumalai Kesavan Vadakalur , Abdullah Mohammad Sufian , Sankar Jayendira P , R Kalaichelvi
Published: April 2021

The English language pronunciation is a sub-skill of speaking modules during the learning process of a second language. Accurate pronunciation is not followed enough by Bangladesh students in speaking English It was found that the participants face barriers while pronouncing English. However, it is ignored and even provided the least attention by them. In order to explore the pronunciation barriers of vowels and consonants of Bangladesh expatriate learners and to identify remedial measures, this study stresses about four aspects of pronunciation: vowel confusion and insertion, missing stress sounds, sounds’ errors cause of written form, and absence of fricatives. The study emphasizes on the value and status of pronunciation and overcame the approach of it among Bangladesh expatriate students. A pronunciation test was conducted with 8 Bangladesh expatriate learners with an age range of 20-25 years and the participants were asked to pronounce 7-8 words in every aspect, recorded their voice and documented for analysis along with observation of the Bangladesh expatriate learners at King Saud University. The study reveals that Bangladeshi students have many errors on the way to the correct vocalization of English sounds, which are mainly the influence of their mother tongue. Bangladeshi Learners could not make the distinction between long and short vowels. To overcome this problem, learners need to participate pronunciation practice in the formal assessment process in addition to language lessons and also focus their attention on conversation through multimedia.

Published: April 2021

A study was undertaken to assess the relationship between agriculture and emigration in Manapang Village Development Committee (VDC) of Tanahun District, Nepal. A total of 120 randomly sampled households were interviewed using a semi-structured questionnaire. Results showed that the average land holding size, irrigated land holding size, livestock holding, income from agriculture, and investment of household income in agriculture were found to be higher in non-migrating households than in migrating households, whereas total household income was higher in migrating households than in non-migrating ones. The marginal value productivity of labor was lower for major crops than that of average wage rate from non-farm work. The size of abandoned land was higher in migrating than non-migrating households. The average share of remittances in household income was 62.50 % in migrating household. Higher share of the remittances was used for consumption purposes, but only 5 % was used in agriculture. Findings revealed that although emigration has a positive effect on the overall economy in the rural households, however, agricultural productivity is suffered.

Published: April 2021

Purpose: To document the nutritional risk in adults with oculopharyngeal muscular dystrophy (OPMD) and its association with oropharyngeal dysphagia.

Methods: In this cross-sectional study, 33 adults with molecular confirmation of OPMD between 50 and 75 years old were recruited from the registry of a university-affiliated neuromuscular clinic. Nutritional risk was assessed with the French version of Seniors in the Community: Risk Evaluation for Eating and Nutrition II (SCREEN II), whereas the severity of dysphagia was assessed using the French-Canadian version of the Sydney Swallow Questionnaire. Anthropometric measurements were performed with standardized procedures.

Results: SCREEN II scores showed high nutritional risk for 81.8% of OPMD participants with 6 factors contributing to nutritional risk in at least 50% of the sample. Pearson’s correlational analysis showed a significant moderate relationship between dysphagia and nutritional risk (r = −0.470; P = 0.006).

Conclusion: To our knowledge, this study is the first to investigate the nutritional risk of adults with OPMD. Our results indicate that individuals with OPMD may be at high nutritional risk mostly associated with swallowing difficulty, in the absence of a low body mass index. The present study highlights the need for dietary counseling in OPMD.

Published: April 2021

Purpose: To examine associations between preschoolers’ diet quality and parent and child socio-demographic variables.

Methods: Cross-sectional analysis with 117 preschoolers. Parents reported socio-demographics and their children’s diet using 3-day food records. Diet quality was assessed using the Healthy Eating Index (HEI) 2015. Linear regression models were used to analyze associations between socio-demographics and HEI scores.

Results: A total of 86% of children had an HEI-2015 score in the “needs improvement” category (51–80 out of a maximum of 100). Children’s overall HEI-2015 score was inversely associated with children’s age (β = −0.19, 95% CI −0.37, −0.02). Parental education was positively associated with children’s overall HEI score (β = 9.58, 95% CI 3.81, 15.35) and with scores for total fruit (β = 1.00, 95% CI 0.39, 1.76), vegetables (β = 1.11, 95% CI 0.03, 2.18), total protein (β = 1.06, 95% CI 0.28, 1.84), and seafood/plant protein (β = 1.67, 95% CI 0.43, 2.89) components. Children who identified as Caucasian (β = 4.29, 95% CI 2.46, 6.14), had a Caucasian parent (β = 3.01, 95% CI 0.78, 5.25), or parents who were born in Canada (β = 2.32, 95% CI 0.53, 4.11) had higher scores for dairy.

Conclusion: Our results suggest that preschoolers’ diet quality needs improvement and that children’s diet quality varies by children’s age and parental education level.

Published: April 2021

Investment can be defined as an activity to postpone consumption at the present time with the aim to obtain maximum profits in the future. However, the greater the benefits, the greater the risk. For that we need a way to predict how much the risk will be borne. Modelling data that experiences heteroscedasticity and asymmetricity can use the Asymmetric Power Autoregressive Conditional Heteroscedasticity (APARCH) model. This research discusses the time series data risk analysis using the Value at Risk-Asymmetric Power Autoregressive Conditional Heteroscedasticity (VaR-APARCH) model using the daily closing price data of Bitcoin USD period January 1 2019 to 31 December 2019. The best APARCH model was chosen based on the value of Akaike's Information Criterion (AIC). From the analysis results obtained the best model, namely ARIMA (6,1,1) and APARCH (1,1) with the risk of loss in the initial investment of IDR 100,000,000 in the next day IDR 26,617,000. The results of this study can be used as additional information and apply knowledge about the risk of investing in Bitcoin with the VaR-APARCH model.

Published: April 2021

The research purpose shown in this article is describing the time dependent reproduction number of coronavirus called by COVID-19 in the new normal period  for 3 types areas, i.e. small, medium and global areas by considering the number of people in these areas.  It is known that in early June 2020, Indonesia has claimed to open activities during the pandemic with the new normal system. Though the number of COVID-19 cases is still increasing in almost infected areas, normal activities are coming back with healty care protocols where public areas are opened as usual with certain restrictions. In order to have observations of spreading impact of COVID-19, the basic reproduction number (Ro)  i.e. the reproduction number (Ro) is the ratio between 2 parameters of SIR model where SIR stands for Susceptible individuals, Infected individuals, and Recovered individuals respectively. The reproduction numbers  are computed as discrete values depending on time. The used research method is  finite difference scheme for computing rate of change parameters in SIR models based on the COVID-19 cases in Indonesia (global area), Jakarta (medium area) and Salatiga (small area) by considering the number of people in these areas respectively. The simple forward finite difference is employed to the SIR model to have time dependent of parameters. The second approach is using the governing linear system to obtain the values of parameter daily. These parameters are computed for each day such that the values of Ro are obtained as function of time. The research result shows that 3 types areas give the same profiles of parameters that the rate of changes of reproduction numbers are decreasing with respect to time. This concludes that the reproduction numbers are most likely decreasing.
Analysis of Students' Errors in Solving Word Problems Viewed from Mathematical Resilience
Authors: Haerani Agus , Novianingsih Khusnul , Turmudi Turmudi
Published: April 2021

Many students in the world have difficulty in solving word problems, including students in Indonesia. TIMSS has shown that only eight percent of Indonesian participants are able to solve word problems, this result is hugely lower than the international average of 18 percent. One of the factors that cause students' errors in solving word problems is mathematical resilience. Thus, this study aims to analyze students' misconceptions in solving word problems viewed by their mathematical strength. This study was conducted for sixth-grade students in one of the elementary schools in Bandung. This study was qualitative descriptive research. In this study, there were four steps: selecting the word problems, answering the issues, filling out a mathematical resilience questionnaire, and interviewing. Students were encouraged to respond to a three-word question within 30 minutes, filling out a mathematical resilience questionnaire followed by the interview. This study showed that the students' errors in solving word problems were including comprehension, transformation, and process skill errors. Based on mathematical resilience, students with a low level of resilience predominantly carried out comprehension errors. In contrast, students with a moderate level of resilience more dominant made transformation errors. Meanwhile, students with high resilience completed more questions correctly, although several students seemed to have made process skills errors. This study's limitation is the data obtained online so that the respondents completed the instrument exceeds the given time. Further researches are suggested to conduct directly in the classroom to maximize the accuracy of the study.

Human capital as an integral factor of social and economic development
Authors: Lopatynskyi Yurii , Kobelia Zoriana , Sheliuzhak Ivanna
Published: April 2021

The article examines human capital in the categorical and structural aspect, identifies the main features of long-term investment in human capital, which can recoup the costs of the enterprise and significantly improve the financial and economic performance of the organization as a whole in the future. It is emphasized that the employee is not an expense of the enterprise, but a strategic resource of the company.
The purpose of the article is to define human capital as an integral factor of socio-economic development of the state, enterprise, institution, organization, as well as to outline the pros and cons of investing in human capital.
The advantages and disadvantages for investors who want to invest in the development of an individual worker or group of workers are identified. Among the advantages are the improvement of service quality, productivity growth and financial indicators, the formation of a stable socio-psychological climate in the team, and the involvement of highly qualified workers. Among the main disadvantages of investing in human capital are financial risk and lost time, possible dishonesty on the part of the employee, uncertain outcome.
Human capital at the macro level is studied through the human development index in Ukraine and Poland. The decline in the index is due to the coronavirus pandemic, which has caused an economic downturn in many countries around the world.
Emphasis is placed on the fact that human capital is an integral part of national development and effective personnel policy of the organization. A modern manager must consider his subordinates as an untapped potential of the organization that needs to be developed. The skills and abilities of employees "wear out" quickly, as changes in the external environment change and displace those people who do not want to adapt to modern conditions of existence and development.
National model of state price regulation: a microeconomic approach
Authors: Simonenko Lesia , Yakobchuk Valentyna , Vlasenko Olena
Published: April 2021

In the system of national public administration, the practices of regulating economic processes in general and prices in particular are approved. Consumers are also "in favour of" such actions by the state, as they associate them with consumer support. Government Resolution №341 of 22.04.2020 “On Measures to Stabilize Prices for Goods…” introduced state regulation of prices by declaring changes in retail prices for goods of “social significance”. This list contains goods where markets are different in their competitive nature, so it is not possible to regulate them by the same method. The necessity of price regulation measures, even for a limited list of goods, is the subject of this article.
In case of perfect competition, firms that produce, for example, buckwheat, granulated sugar, wheat flour accept the market price, hence government regulation will lead to a deficit / surplus. Activities of producers of pasta of domestic production (vermicelli from premium wheat flour), pasteurized milk with fat content of 2.5 percent (in the film), rye-wheat bread, belong to the monopolistic competition. Typically, their activities are self-sustaining (break-even), hence administrative price decrease will lead to a reduction in production with all associated consequences. Markets of chicken eggs of category C1, poultry (chicken carcass), still mineral water, butter with fat content of 72.5 percent, in microeconomics are "oligopolies", which suggests interdependence in pricing. Therefore, producers themselves "disapprove" state intervention that violates competitive conditions. Natural gas and electricity markets are monopolized. The tool to reduce prices is to expand the number of market operators. To this end, an alternative to state regulation of prices is further development of a competitive environment and entrepreneurship

Published: April 2021

The overall situation of the economic activity of the population in the Carpathian region including the necessity of enterprises for employees was determined. The structure of the necessity of workers in enterprises by economic activity for the regions of the Carpathian region was analyzed. The prospects of IT employment with the rapid development of it in the cities of Lviv and Ivano-Frankivsk were found. Applied and possible proliferation risks in the region of freelance was outlined.
Improvement and development of regional labor markets, intellectual, labor potential of the Carpathian region is characterized by quite contradictory and ambiguous trends. On the one hand, due to the latest conditions and the crisis, the labor markets are showing declining dynamics, in the regions cannot stabilize and control the situation against the background of today's macro-crisis events. On the other hand, against this background, we observe spontaneous, uncontrolled processes of employment in the field of IT and programming, which is especially true for Lviv and Ivano-Frankivsk regions. We say that a new creative class is being formed, the core of which is those who are engaged in science and technology, education, culture, art, music, entertainment industry.
Today it is necessary to develop and improve the regionalization of regulation of regional systems; to provide a controlled and regulated process of development of employees in the IT sphere; to form and institutionalize a new ideology of employment in the population with a combination of its various types through the creation and dissemination of flexible working hours.

Die Untersuchung der Gründe für den Studienabbruch von Studierenden in MINT-Fächern ist wegen des akuten Fachkräftemangels von großer Bedeutung. Dabei ist bisher wenig über Unterschiede zwischen MINT-Studiengängen, aber auch im Vergleich zu anderen Studiengängen, hinsichtlich der Abbruchgründe bekannt. Die längsschnittlich angelegte Studie untersucht daher individuelle Einflussfaktoren auf den Studienerfolg und Studienabbruch in zwei typischen MINT-Studiengängen (Chemie und Maschinenbau) und kontrastierend dazu in Studiengängen aus dem sozialwissenschaftlichen Bereich (Politikwissenschaft, Soziologie, Soziale Arbeit). Während in bisherigen Studien (z.B. Heublein et al., 2017) fachübergreifende Prädiktoren für den Studienabbruch identifiziert werden konnten, wurde in den Analysen dieser Studie festgestellt, dass sich diese zwischen den Fächern und auch zwischen unterschiedlichen Hochschultypen sehr unterschiedlich auswirken. Vor allem die Sozialwissenschaften zeigen im Vergleich zu den MINT-Fächern einen deutlich geringeren Einfluss des Fachwissens auf den Studienabbruch.
Ozone and Particulate Matter Exposure and Alzheimer’s Disease: A Review of Human and Animal Studies
Authors: Liu Rui-Ming , Chong Zechen , Chen Jiu-Chiuan
Published: April 2021

Alzheimer’s disease (AD), an aging-related neurodegenerative disease, is a major cause of dementia in the elderly. Although the early-onset (familial) AD is attributed to mutations in the genes coding for amyloid-β protein precursor (AβPP) and presenilin 1/presenilin 2 (PS1/PS2), the cause for the late-onset AD (LOAD), which accounts for more than 95% of AD cases, remains unclear. Aging is the greatest risk factor for LOAD, whereas the apolipo protein E4 allele (APOEε4) is believed to be a major genetic risk factor in acquiring LOAD, with female APOE ε4 carriers at highest risk. Nonetheless, not all the elderly, even older female APOE ε4 carriers, develop LOAD, suggesting that other factors, including environmental exposure, must play a role. This review summarizes recent studies that show a potential role of environmental exposure, especially ozone and particulate matter exposure, in the development of AD. Interactions between environmental exposure, genetic risk factor (APOE ε4), and sex in AD pathophysiology are also discussed briefly. Identification of environmental risk factor(s) and elucidation of the complex interactions between genetic and environmental risk factors plus aging and female sex in the onset of AD will be a key to our understanding of the etiology and pathogenesis of AD and the development of the strategies for its prevention and treatment.
A Critical Proton MR Spectroscopy Marker of Alzheimer’s Disease Early Neurodegenerative Change: Low Hippocampal NAA/Cr Ratio Impacts APOE ε4 Mexico City Children and Their Parents

Severe air pollution exposures produce systemic, respiratory, myocardial, and brain inflammation and Alzheimer’s disease (AD) hallmarks in clinically healthy children. We tested whether hippocampal metabolite ratios are associated with contrasting levels of air pollution, APOE, and body mass index (BMI) in paired healthy children and one parent sharing the same APOE alleles. We used 1H-MRS to interrogate bilateral hippocampal single-voxel in 57 children (12.45 ± 3.4 years) and their 48 parents (37.5 ± 6.78 years) from a low pollution city versus Mexico City (MC). NAA/Cr, Cho/Cr, and mI/Cr metabolite ratios were analyzed. The right hippocampus NAA/Cr ratio was significantly different between cohorts (p = 0.007). The NAA/Cr ratio in right hippocampus in controls versus APOE ε4 MC children and in left hippocampus in MC APOE ε4 parents versus their children was significantly different after adjusting for age, gender, and BMI (p = 0.027 and 0.01, respectively). The NAA/Cr ratio is considered reflective of neuronal density/functional integrity/loss of synapses/higher pTau burden, thus a significant decrease in hippocampal NAA/Cr ratios may constitute a spectral marker of early neurodegeneration in young urbanites. Decreases in NAA/Cr correlate well with cognitive function, behavioral symptoms, and dementia severity; thus, since the progression of AD starts decades before clinical diagnosis, our findings support the hypothesis that under chronic exposures to fine particulate matter and ozone above the standards, neurodegenerative processes start in childhood and APOE ε4 carriers are at higher risk. Gene and environmental factors are critical in the development of AD and the identification and neuroprotection of young urbanites at high risk must become a public health priority.
Air Pollution as Risk Factor for Mental Disorders: In Search for a Possible Link with Alzheimer’s Disease and Schizophrenia
Authors: Attademo Luigi , Bernardini Francesco
Published: April 2021

As a global problem that has increasingly been causing worldwide concern, air pollution poses a significant and serious environmental risk to health. Risks of cardiovascular and respiratory diseases, as well as various types of cancer, have been consistently associated with the exposure to air pollutants. More recently, various studies have also shown that the central nervous system is also attacked by air pollution. Air pollution appears to be strongly associated with a higher risk of cognitive defects, neurodevelopmental (e.g., schizophrenia) and neurodegenerative (e.g., Alzheimer’s disease) disorders. Subjects with schizophrenia, as well as subjects with Alzheimer’s disease, experience a variety of neuropsychological deficits and cognitive impairments. This determines an adverse effect on social and professional functioning, and it contributes to the long-term disease burden. However, no final conclusions have been drawn on the matter of the direct relationship between schizophrenia and Alzheimer’s disease. In recent years, the topic of urbanicity and mental health has become increasingly important. Urban exposure to environmental toxins and pollution is currently described as a reliable risk factor for schizophrenia and other psychoses, and it has been demonstrated more and more how exposure to air pollutants is associated with increased risk of dementia. Pathways by which air pollution can target and damage the brain, leading to an increased risk for developing schizophrenia and Alzheimer’s disease, are multiple and complex. Results from epidemiological studies suggest potential associations, but are still insufficient to confirm causality. Further studies are needed in order to verify this hypothesis. And if confirmed, the clinical implications could be of substantial relevance for both public and mental health.

The organic vegetable industry is flourishing due to consumers preference for organically grown produce over traditionally produced vegetables. As a result, an increase in the variety and selection of many vegetables in retail supermarkets and restaurants throughout the United States has occurred recently. With the new regulation (October 2000) requiring organic seed sources for organically labeled vegetables, many organic growers are searching for certified organic seed. Smaller seed companies have produced the majority of organically produced seed to date. The commercial seed sector is starting to provide a more diverse selection of cultivars, yet there are still many hybrids that are not yet available. For growers in Florida, there is opportunity to produce organic, though it is not widely practiced. This report serves as a guide to organic seed production in Florida. This document is HS981, one of a series of the Department of Horticultural Sciences, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.

Southern Lyctus Beetle, Lyctus planicollis LeConte (Insecta: Coleoptera: Bostrichidae: Lyctinae)
Authors: Brammer Angela S.
Published: April 2021

The term "powderpost beetle" is often used to describe two families: Anobiidae (deathwatch beetles) and Bostrichidae (false powderpost beetles). The true powderpost beetles, of the subfamily Lyctinae (formerly family Lyctidae) within the family Bostrichidae, earned their common name from the very fine powdery frass found in their tunnels. Eleven lyctine species have been found in the U.S. Florida has three Lyctus species and one species each in the genera Minthea and Trogoxylon (both subfamily Lyctinae). Of the three Lyctusspecies, one is an introduced seed feeder and another is rarely encountered. Only L. planicollis is common and destructive throughout the South. This document is EENY-283, one of a series of Featured Creatures from the Entomology and Nematology Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.

Published: April 2021

Introduction: Hereditary Gingival Enlargement (HGF), a rare entity, is also known as familial elephantiasis, elephantiasis gingivae, diffuse fibromatosis. It is a benign, non-haemorrhagic fibrous enlargement of gingival tissue. It is frequently a component feature of many syndromes. Jones syndrome is one such syndrome, characterized by gingival overgrowth and progressive deafness.

Case report: A 27-year-old male patient reported to the Department of Oral Medicine and Radiology with the chief complaint of swollen gums for the past 7 years. The patient also complained of bleeding gums on brushing. The medical history stated a concurrent gradual hearing loss 7 years back. An incisional biopsy was done to confirm the fibrous nature of the diagnosis.

Conclusion: This reporting is of unique case that remained undiagnosed for almost a decade. It also emphasises the need of a multidisciplinary approach during diagnosis and treatment.

Authors: Rafidiyah Nabilah
Published: April 2021

Sulphur-doped TiO2 samples were prepared by sol gel method using thiourea as sulphur source. The amount of thiourea solutions are 0; 0.5; 1.0; 1.5 and 2 ml, respectively. Sulphur-doped TiO2 was calcinated at 450°C. Sulphur-doped TiO2 and pure TiO2 were characterized by X-Ray Diffraction (XRD), Transmission Electron Microscopy (TEM). Photo catalyst tests were carried out under sunlight and UV lamp. Based on XRD characterization, the samples are anatase phase. Furthermore, particle size was calculated using Scherrer equation and results of 8.94 and 12.98 nm, respectively for TBT-1.5 and TBT-0.5. TEM characterization showed that particle size of sulphur-doped TiO2 and pure TiO2 are 8.6 and 12.5 nm. Compared to TiO2 without doping, sulphur-doped TiO2 has a better photo catalyst activity for degradation of remazol golden yellow under visible light.

Authors: Achiruddin
Published: April 2021

Polymer composite roof tiles are produced from palm oil boiler ash and used rubber thread fibers waste. The material was strengthened by asphalt through a molding and pressurized conventional technique of sand, palm oil boiler ash waste, rubber thread fibers waste, asphalt and epoxy resin mixture. The composition of boiler ash and rubber thread fibers varied of 20% : 0%, 18% : 2%, 16% : 4%, 14% : 6%, 12% : 8%, 10% : 10%. The results were tested for physical (density and water absorption), mechanical (compressive, impact and tensile strength) and thermal (Differential Thermal Analysis) properties. The characterization shows that the optimum mixture of sand, ash, thread, asphalt and resin compositions are 55% : 12% : 8% : 10% : 15% respectively, with the highest density of 1.64 gram/cm3, waster absorption value of 1.72%, 77.68 kJ/m2 impact value, 19.373 MPa tensile strength and 360°C for differential thermal analysis temperature. Those results meet the SNI standard for existing roof tiles. This shows that the materials used in the research can be a cheap and environmentally friendly alternative to roof tile raw materials.

Authors: Sembiring Manis
Published: April 2021

Coal briquettes are solid materials that can be used as fuels. The composition of this solid fuels are mixed by clay as the ashes binder, rice husks powder as flame additives, and starch flour as adhesive materials. These materials were prepared in different ratio to be mixed homogeneously which are determined accordingly. The fabrication was conducted by mixing methods, and pressed by hydraulic press within 3100 KPa. The results were placed inside an oven to be dried for 24 hours within 85oC of temperature, followed by 24 hours of allowing standing in room temperature. Afterward, the characterizations of the coal briquettes were done by performing density and compressive strength, while the others physical properties such as specific heat, combustion, and purity properties were also tested. The physical properties showed that coal briquettes are flammable and high ignition characteristics. The stability and speed of combustion to fire have continuous and fixed combustion indicated by the presence of solid ashes. The samples suggested that the M1 samples provided fragile ashes with mass loss accounted for 56.33%, and it has the highest specific heat values accounted for 246.66 Kcal/Kg. Meanwhile, the lowest specific heat value was 162.26 Kcal/Kg which was M4 samples with mass loss for 34.53%.

Management of Electric Field under the Sag of High Voltage Overhead Transmission Lines
Authors: Rianna Martha
Published: April 2021

There have been many methods used to determine the electric field strength under the 150 KV overhead transmission lines (OHTL). Since it is simple and can be used for a homogeneous and multilayer medium, the method chosen for modeling the electric field under the OHTL is the complex image method (CIM). The results obtained show that the electric field strength obtained by the CIM is in agreement with that obtained by Complex Determine Method (CDM). Furthermore, the results obtained from the CIM model fit well with the field data. The OHTL height that must be raised so that the electric field strength under the OHTL will meet the WHO quality standards is 3 m at location A and 2 m at location B. These results show that modelling the electric field under the OHTL using CIM is exellent.
