Authors: Prihantoro Satrio , Widyana Rahma , Setiawan Ezra Putranda
Published: April 2022

AbstractLanguage learning strategy is one of the main factors that help determine how well our students learn a second or foreign language (Oxford, 2003). Research has shown that more effective language learners use more and better learning strategies than poorer language learners (Rubin, 1975; Stern, 1975). This research investigates the difference in ESL learning strategies used by students with different levels of ESL learner motivation and how gender plays a role in both. Strategy Inventory of Language Learning (SILL; Oxford, 1990) and English Language Learner Motivation Scale (ELLMS; Ardasheva, Tong and Tretter, 2012) were used and adopted to measure English language learning strategies and English language learner motivation, by employing 65 male students and 75 female students from Budi Utama Junior High School as participants. The data analyzed showed that there was significant difference in ESL learning strategies used by the students with different levels of ESL learner motivation but there is no significant role of gender in ESL learner motivation and ESL learning strategies.Keywords: ESL, gender, learner motivation, learning strategy.DOI:doi.org/10.24071/llt.2018.210101

Published: April 2022

Reading has become a major concern of EFL educators. Reading does not only help students learn foreign languages, but it is also believed that it has a strong link with critical thinking skills. A reader response approach in collaborative works, adapted from literary theory, is believed to be beneficial for the students. Therefore, this study aims at investigating the answers to these two questions: (1) how are the collaborative reader responses implemented in Critical Reading and Writing II? and (2) To what extent does reader response approaches promote students critical thinking skills? With these questions in mind, the researchers collect the data by involving 24 participants from CRW II (Critical Reading and Writing) class. The data gathered from classroom observations, online archives and students reflections are analyzed descriptively, using qualitative case study method. It is hoped that the implementation of this approach can be useful not only to improve students reading skills, but also to provide more opportunity for students to exercise their critical thinking skills.

Indonesian EFL students of the 5th semester taken the course of Academic Speaking in a private university (n=30) who were selected randomly responded Creative Personality Scale (CPS) and Self-Rating of Creativity. For the former, they described themselves by checking off 18 positively scored and 12 negatively scored items which were given a value of +1 and a value of -1, respectively. The latter was assessed by using eight items from the creativity scale. The 7-point Likert-type scales (1=strongly disagree, 7=strongly agree) were made to respond these items. Following this, the students' monologues based on five themes were scored using the IELTS Speaking Test Descriptor. The data were analyzed using Spearman rank-order correlation coefficient, pattern matching, and explanation building. The finding shows a significant correlation between EFL learners' creativity and their speaking ability (? = .961). The students also faced up to the cultural constraints in advancing their creativity. This study should, therefore, be of value to practitioners wishing to provide EFL students with appropriate materials that are addressed to enhance their speaking ability.

Published: April 2022

Teacher belief is valuable to accomplish effective teaching learning processes. Prospective teachers utilize their beliefs to practice their teaching competence. Accordingly, it is essential to explore prospective teachers beliefs as the teachers exhibit the beliefs in their teaching preparations and practices. Alongside, TEYL requires a unique process. To enhance TEYL prospective teachers consciousness of the beliefs they hold, this study attempts to match them with the teaching designs and practices. This survey study involves TEYL prospective teachers in responding to a questionnaire concerning with their beliefs about teaching. Their Lesson Plans and teaching performance videos are correspondingly analyzed to scrutinize how equivalent they are with the beliefs. It is quite thought-provoking to discover that there are inconsistencies between prospective teachers beliefs with the realization in their lesson planning and performances. This affords insights to boost our awareness in building teachers beliefs as to maximize learning teaching outcome.

This study collected 112 written feedback from 5 teachers and the corresponding numerical scores in the students report cards from one of the private Primary Schools in Surabaya. The teachers written feedback was analyzed based on the principles of evaluation. The results of the analysis indicated that none of the teachers wrote feedback which met the criteria of an ideal feedback covering praise, criticism, and suggestion equally at the same time. All teachers only gave praise mostly to very good and excellent students; they almost never gave criticism and suggestion to them. To the low achieving students, the teachers mostly gave criticism and suggestion, and almost never gave any praise. In regard to the alignment between the teachers written feedback and the students numerical scores in the report cards, the finding indicated that the teachers written feedback was well aligned with the students numerical scores.
CULTURAL TRANSLATION OF PROVERBS FROM NEPALI INTO ENGLISH
Authors: Neupane Nabaraj
Published: April 2022

Proverbs are witty, pithy, and epigrammatic expressions. They are idiosyncratic, being based on a specific culture. As cultural translation is difficult, translation of proverbs is not easy. Yet, translation practices on such genre have been appearing. In such a scenario, some such practices are found in the domain of Nepali into English translations. In this background, the present study aims at reviewing the available models for translating proverbs and recommending one, which can be used for translating Nepali proverbs into English. To achieve the objectives, I collected twenty proverbs purposively from Lall (1991) and Sharma (2000), primarily because I could deal only with twenty in a short period and limited space. By way of qualitative analysis and interpretation and by testing Wilson's (2009) model, I have concluded that the model is applicable for the purpose.

Authors: Meisani Diah Royani
Published: April 2022

As internet technology has become more influential and cultured, online or e-resources are nowadays present as alternatives for teaching materials. The resources themselves play an important role in lesson planning, instruction delivery, and take a part in determining the learning achievement. This study was conducted to investigate the forces that drive elementary school English teachers (N = 178) in utilizing online teaching materials together with the benefits and challenges they faced in using them. From the questionnaire, it was revealed that almost all respondents used and benefited from online resources taken from Google, YouTube, and other search engines. Further investigation through interviews revealed prevalent responses on e-learning materials utilization that are categorized as follows: accessibility, practicality, authenticity, and variety. Other benefits, such as the features of online resources that positively attract young learners in foreign language learning are meaningfully advantageous as they improve students’ learning engagement (SLE). These findings support evidence for e-learning resources as teaching materials for overcoming the shortage of teaching guidelines and materials in English for Young Learners (EYL) classes. Teachers’ responses towards the challenges in using this type of material lead to the implication that schools and other related stakeholders should take serious concerns to equip EYL teachers with professional development or in-service training, particularly in teaching material development and online resources integration.

Published: April 2022

Autoimmune mechanisms have been implicated in the negative effects of vaccines on female reproductive health. This study evaluates the endogenous levels of self-reactive antibodies and ovarian reserve-associated hormones before and after immunization with the domestically developed Gam-COVID-Vac combined vector vaccine to check for possible reproductive sequelae. The prospective study enrolled 120 women aged 18–49, subject to vaccination with Gam-COVID-Vac. Ovarian reserve was assessed prior to vaccination and 90 days after the first component injection. Profiles of specific antibodies to self-antigens, including phospholipids, nuclear antigens, FSH, progesterone, and also thyroid, ovarian, trophoblast, and zona pellucida antigens, were assessed at the same time points by enzyme immunoassay. Overall, the vaccination had no effect on the levels of ovarian reserve-associated hormones and autoantibodies, apart from a transient increase in positivity for antiphosphatidylethanolamine IgM and anti-dsDNA IgG. Seroprevalence of elevated serum autoantibodies constituted 70.8% before and 75% after vaccination. According to the results, immunization with Gam-COVID-Vac does not affect ovarian reserve or autoimmune status, thus being safe for the female reproductive potential.

Published: April 2022

Solving research problems within the framework of creating a single digital circuit in healthcare requires

a research conducted on the basis of depersonalized medical data stored in the information systems of medical institutions. There are described the methods of mathematical statistics aimed at comparing the average values of two types of samples: quantitative and binary in order to determine the relationship between blood test indicators and working conditions. Comparison of methods and results of comparison of quantitative and binary samples is made. The expediency of processing small structured samples taken out from the medical information system is substantiated. The study was conducted by using medical data stored in a transactional medical information system. During the preparation process, the data were depersonalized, cleaned from the inevitable noise and defects. Binarization of the values

of the indicators was performed by comparing them with the known boundaries of the interval of the medical norm.

A method was developed to bring the samples to uniformity simultaneously on the gender and age signs of the patients. There have been revealed the parameters of laboratory tests, which have a statistically significant relationship with working conditions identified for 4 groups under study. These groups were corresponding to the following work conditions complexes: influence of electromagnetic emanation, noise and vibrations, working conditions in regional office services. The proposed methods and received results will increase the accuracy of the performed risk assessments of occupational morbidity and become the base for studying the mechanism of the work conditions influencing the health. They will contribute to improvement of the analysis of the data collected in the medical information systems and management decision-making in healthcare.

Published: April 2022

We uncover the major drivers of each macroeconomic variable and the real exchange rate at the business cycle frequency in G7 countries. In each country, the main drivers of key macro variables resemble each other and none of those account for a large fraction of the real exchange rate variances. We then estimate the dominant driver of the real exchange rate and find that (i) the shock is largely orthogonal to macro variables and (ii) the shock generates a significant deviation of the uncovered interest parity condition. We analyze international business cycle models that are consistent with our findings.

Because they will be the conveyor of microbial contamination, bacteria. In Indoor environment microorganisms that may enter in HVAC system can be generated in many different ways. e.g. People talking, sneezing, carpet and toilet flushing process. And generated, spread by this many ways can survive in various HVAC components such as air ducts, filters, heat exchangers and fan coils. Other HVAC components and metabolism for various bacteria, microorganisms occupy. During the operation of the system bacteria and microorganisms obtain suitable environmental conditions such as temperature, moisture, nutrients conditions for their growth. And when their growth extents, these microorganisms and bacteria diffuse in system in form of bio-aerosols, accumulated dust and spread into indoors with supply air flow. In general, the microbial contamination source of HVAC system, so it is difficult to eliminate the microbial contamination at source. So some methods are able to kill microorganisms by air purification technology. The air purification technology includes different method by which we can maintain the good indoor air quality in HVAC system or applications to fight against the microorganisms, viruses and bacteria.

Authors: Yankova I. , Shinkov A. , Kovatcheva R.
Published: April 2022

Percutaneous ethanol ablation (PEA) is an alternative non-surgical method for the treatment of patients with primary hyperparathyroidism (PHPT), suitable in cases with comorbidities and high surgical risk.

The aim of the present study was to evaluate the results of PEA in patients with PHPT at the early stages of follow-up.

Materials and methods: The study included 35 patients (30 women and 5 men, mean age 59.7 ± 12.4 years) with biochemical and hormonal data of PHPT and localized parathyroid adenoma (PTA) by ultrasound, nuclear scan, FNB with cytology and evaluation of PTH in the needle washout. All patients were at high surgical risk or refused surgical treatment. PEA was applied and changes in the PTA volume and calcium-phosphate metabolism were monitored at the third (M3) and sixth (M6) months after the procedure.

Results: Normocalcaemia was achieved in 26 patients (74.3%) at M3 and persisted at M6 in 22 of them. A second course of PEA was administered in 11 patients with persistent hypercalcaemia at M3 and M6, respectively. Compared to the baseline, the mean PTA volume decreased significantly by 53% at M3 and 67% at M6 (p < 0.001). Side effects including local pain, edema and dysphonia were observed in 5 patients (14.3%).

Conclusion: PEA is an efficient and safe treatment modality for the management of PHPT. A significant reduction in PTA volume and a normalization of serum calcium and PTH levels were observed at the early stages of follow-up.

Published: April 2022

This paper analyses and discusses the monthly and annual changes of chemical oxygen demand (COD), total nitrogen (TN), and total phosphorus (TP) concentrations from main sewage discharge ports in Xiangshan Bay. Using monitoring data obtained from 2010 to 2019, it systematically examines the monthly variation characteristics of the sewage discharge ports and the interannual changes in the fluxes of major pollutants into the sea. The concentrations of COD, TN, and TP, which were relatively high in November and January-March, generally declined. The annual and monthly changes fluctuated, but the flux into the sea generally decreased. The ecological environment of the nearby sea area is adversely affected, chiefly by land-based pollutants. During the five-year period, COD mainly came from soil erosion and domestic pollution, while TN and TP mainly came from agricultural activities and soil erosion. Hence, it is both necessary and urgent to improve the management of the sewage outfalls from land sources into the sea.

Published: April 2022

Phytosanitary treatments with pesticides are widely used to control pests and diseases in vineyards. An important part of the dispersed pesticide reaches the soil, affecting the fauna, producing quantitative and qualitative changes in the edaphic population’s structure and physiological activities. This study aims to evaluate the temporal dynamics of the soil macro and mesofauna through different pesticide treatment periods, where fungicides are the dominant pest control agent. A field experiment was carried out in Boumerdes, a specific viticultural region in Algeria. Soil samples were taken during three periods, before, during, and after treatment with pesticides, using the quadrat method at three soil depths. During these three periods, the soil macro and mesofauna were observed and compared. The results showed significant differences in the composition of invertebrate communities that tended to disappear during pesticide application. The structure and diversity of 11 invertebrate classes, including Collembola, changed along the treatment gradient. The effects of sampling periods on occurrence, abundance, and taxon richness were consistently negative. These indices were significantly lower after pesticide application. Therefore, we can suppose that climatic factors and pesticide treatements are the main factors affecting the activity and density of all classes of invertebrates, but these effects vary between the functional groups of soil biota.

Published: April 2022

This study aims to design vehicle routes based on cost minimisation and the minimisation of greenhouse gasses (GHG) emissions to help companies solve the vehicle routing problem with pickup and delivery (VRPPD) via particle swarm optimisation (PSO). An effective metaheuristics search technique called particle swarm optimisation (PSO) was applied to design the optimal route for these problems. Simulated data from Li and Lim (2001) were used to evaluate the PSO performance for solving green vehicle routing problems with pickup and delivery (Green VRPPD). The findings suggest that green vehicle routing problems with pickup and delivery should be used when distributing products to customers living in a specific area called a cluster. However, the design of vehicle routes by Green VRPPD costs more when used to distribute products to customers living randomly in a coverage service area. When logistics providers decide to use Green VRPPD instead of VRPPD, they need to be concerned about possible higher costs if an increase in the number of vehicles is needed. PSO has been confirmed for solving VRPPD effectively. The study compared the results based on the use of two different objective functions with fuel consumption from diesel and liquefied petroleum gas (LPG). It indicates that solving VRPPD by considering the emissions of direct greenhouse gases as an objective function provides cleaner routes, rather than considering total cost as the objective function for all test cases. However, as Green VRPPD requires more vehicles and longer travel distances, this requires a greater total cost than considering the total cost as the objective function. Considering the types of fuels used, it is obvious that LPG is more environmentally friendly than diesel by up to 53.61 %. This paper should be of interest to a broad readership, including those concerned with vehicle routing problems, transportation, logistics, and environmental management. The findings suggest that green vehicle routing problems with pickup and delivery should be used when distributing products to a cluster. However, the design of vehicle routes by Green VRPPD costs more when used to distribute products to customers living randomly in a coverage service area. When logistics providers decide to use Green VRPPD instead of VRPPD, they need to be concerned about possible higher costs if an increase in the number of vehicles is needed.
Long-term trend of electric vehicle sales in Thailand
Authors: Chinda Thanwadee
Published: April 2022

This research study aims at examining the long-term trend of EV sales in Thailand, utilising the system dynamics (SD) modelling approach. This approach is commonly used to model complex systems with causal relationships among key factors within the system. The developed SD model consists of five key factors affecting electric vehicle (EV) sales, namely, the environment, economy, charging infrastructure, government support, and battery maintenance. The simulation results show the increase in EV sales by ten times in the next 20 years with implementation plans related to the five key factors. The government support factor is the most important in enhancing EV sales in the short term. Several government support plans should be initiated to attract more EV consumers, such as subsidies and tax reductions. The environment and charging infrastructure factors are crucial to increasing EV sales in the long term. The enforcement of the CO2tax and the provision of charging stations all around the country should be established to achieve a sustainable EV market in the long term. This research study contributes to the Thai government and automotive industry to better understand the complex relationships among key factors affecting EV sales. The related sectors may use the study results to plan for EV campaigns to promote the use of EVs and achieve a sustainable EV market.

Published: April 2022

Natural gas is relatively clean energy source, which emits less greenhouse gases (hereinafter – GHG), compared to other fossil fuels, such as hard and brown coal, and therefore it may be the most feasible resource to ensure smooth energy transition towards Europe’s climate neutrality by 2050. Traditional natural gas can be easily transported and used in liquefied (hereinafter – LNG) or compressed form. As for biomethane, in future it also can be used in liquefied (hereinafter – bioLNG) and compressed form, as well as transported by means of the current natural gas infrastructure. It can also significantly enhance regional and national energy security and independence, which has been challenging for the European Union (hereinafter – EU) over at least several decades.

Issue on energy independence, security of supply, alternative natural gas sources has been in a hotspot of the Baltic energy policy makers as well. Now, considering Russia’s invasion in Ukraine, since late February 2022, a problem of the EU natural gas dependency on the Russian Federation has escalated again and with force never before experienced. The European natural gas prices also hit records, as the natural gas prices in the Netherlands Title Transfer Facility reached 345 euros per megawatt-hour (hereinafter – EUR/MWh) in March 2022.

Therefore, LNG import terminal is the only viable option to reduce national dependency of the so-called pipe gas which in some cases, due to the insufficient interconnections, may be delivered from very limited number of sources. The European policy makers and relevant institutions are currently working towards radical EU natural gas supply diversification, where LNG deliveries coming from outside of Russia will certainly take a central stage.

In case of Latvia, the potential benefits of the LNG terminal development in Skulte were evaluated in order to reduce energy independence of the Russian natural gas deliveries in the Baltic region and to introduce new ways and sources of the natural gas flows to the Baltics. LNG terminal in Skulte could ensure significant capital investment cost reduction comparing to other projects proposed for Latvia in different periods, due to already existing natural gas transmission infrastructure and the relative closeness to the Incukalns underground gas storage (hereinafter – UGS). Various aspects, such as technical, political and economic ones, were analysed to assure that Skulte LNG terminal would be a real asset not only to customers of Latvia, but also to those of the whole Baltic region, where in future it would be possible to use biomethane for efficient utilisation of existing and developing natural gas infrastructure.

In information security systems, the algorithm of the Blum-Blum-Shub (BBS) generator, which is based on the use of a one-way function and is a cryptographically secure pseudorandom number generator, became widespread. In this paper, the problem of the analysis of modified algorithms of the BBS generator operation is considered to improve their statistical characteristics, namely, the sequence repetition period. It has been established that in order to improve the characteristics of the classic BBS algorithm, it is necessary to systematize approaches to change the recurrent equation itself, the relationship between the current and the previous members of the sequence. For this purpose, a generalized unified model of the modification of the classical BBS algorithm is derived. The repetition period with computational complexity were analyzed for classical algorithm and 80 proposed modifications. A gain in statistical characteristics is improved with slight increase in the required computing power of the system. The proposed modified BBS pseudorandom sequence generator can be used in training of students when teaching cryptographic stability of information security systems. The study of this generator combines the knowledge of students acquired in both digital electronics and mathematics.
The Personality Profiles for Contemporary Macedonian Actors
Authors: Pop-Jordanova Nada
Published: April 2022

Theatre is one of the higher cultural activities that characterise us as imaginative, creative and truly human. In general, theatre is an arena in which participants can mentally play, acting out their own fears and fantasies in an experimental way.

The purpose of this study is to investigate the psychological personal characteristics, using the MMPI questionnaire, applied in a sample of Macedonian professional actors.

MMPI is used as an older form of the questionnaire, standardised in ex-Yugoslavia, and then translated into Macedonian. This is all done with a computer.

This research confirms that our (Macedonian) contemporary actors are normal people who function normally in everyday life and generally do not deviate from what in the psychology of personality are denotes as normal/abnormal. Small exceptions are still a rarity!

Some indexes of interest are included in this analysis of personal characteristics of actors.
Inflammatory Bowel Diseases in Renal Transplantat Recipients: A Case Series and Review of the Literature
Authors: Vrus Jakob , Jukić Nikolina Bašić
Published: April 2022

Inflammatory bowel diseases are autoimmune disorders affecting the gastrointestinal tract and producing a wide variety of extraintestinal manifestations. Kidneys are a rare target organ of their extraintestinal activity, but if affected, renal function could deteriorate to end-stage kidney disease, which is curable only by organ transplantation. Renal calculi are the most common pathological kidney manifestation in IBD patients, followed by tubulointerstitial nephritis, glomerulonephritis, and other kidney pathologies.

The liver is the most commonly transplanted organ in IBD patients (primary sclerosing cholangitis and autoimmune hepatitis), and a scarcity of literature on kidney recipients is present to date regarding the incidence of renal insufficiency, kidney transplantations, post-transplant IBD course and further complications such as graft rejection or infections in this specific group of patients. De novo IBD is a paradoxical entity in the setting of rigorous post-transplant immunosuppression.

In this case series, we present three patients who underwent kidney transplantation with a history of an IBD and one patient who developed de novo Crohn’s disease after the deceased donor organ transplant was performed.

Continuous peripheral nerve block, also known as “local anesthetic perineural infusion,” refers to percutaneous placement of a catheter near a peripheral nerve or plexus followed by administration of a local anesthetic through a catheter to provide anesthesia, or analgesia for several days, in some cases even for a month.

This report describes the case of a 7 year old boy with left elbow contracture with limited flexion and extension who was admitted to the Clinic of Pediatric Surgery for redressment of the elbow and physical therapy. An ultrasound-guided axillary brachial plexus block was performed, with placement of a non-tunneled perineural catheter. Redressment of the left elbow was performed twice and before each redressment boluses of local anesthetic were applied through the perineural catheter. Physical therapy was performed painlessly with continuous perineural infusion. On the 5th day of catheter placement, the perineural catheter was removed without any prior complications such as hematoma, infection, catheter dislocation or leakage of local anesthetic.

Our goal is to minimize the psychological and physical trauma to the patient, no matter how immature the patient is. Continuous regional anesthesia in children is a safe technique in postoperative pain management that facilitates early mobilization due to its sufficient analgesia and better comfort. It can provide in-home treatment, with adequate education for patients and parents, and improve rehabilitation in children.

Hickam’s Dictum Incarnate: A Case of Simultaneous Left-Sided Urolithiasis and Ruptured Iliac Artery Aneurysm
Authors: Bouwsema Melissa , Bell Colin
Published: April 2022

A 51-year-old man with a history of nephrolithiasis presented to the Emergency Department after a sudden onset of left-sided groin pain and syncope. At presentation, he described his pain as similar to prior renal colic episodes. At his initial assessment, point of care ultrasound (POCUS) was used, which revealed findings consistent with obstructive renal stones, as well as a substantially enlarged left iliac artery. Computed tomography (CT) imaging confirmed the comorbid diagnoses of left-sided urolithiasis and a ruptured isolated left iliac artery aneurysm. POCUS facilitated expedited definitive imaging and operative management. This case highlights the importance of performing related POCUS studies in reducing anchoring and premature closure bias.
