Authors:   Kremenchuk Mykhailo Ostrohradskyi National University, Hrytsiuk Olena Serhiivna
Published: January 2021

In this paper, methodological and organizational aspects of applying CLIL methodology in teaching computer science for students of universities are analyzed. It is shown that European countries, as well as the United Kingdom, the United States of America, and Canada, where part of the curriculum has been taught in a foreign language for several decades, are most actively introducing content and language integration and promoting an interdisciplinary approach to education. CLIL methodology features and benefits are identified, namely, a comprehensive focus, stimulating learning environment, authenticity, active learning, gradual learning and collaboration. The peculiarity of CLIL methodology is that its use requires a stable elementary skill in the grammar of a foreign language, as well as knowledge of subject-specific language. In accordance with various conditions, CLIL model can be presented in various forms: it can be a full course of a foreign language discipline, a module from a specific topic area, a part of any course, a project, a laboratory workshop, and a research, too. The paper presents a plan for computer science lectures and labs in a foreign language, which contains seven stages, each of which is performed in English. Integration of computer science and teaching in English at the Kremenchuk Mykhailo Ostrohradskyi National University is implemented using developed bilingual course program “Computer for beginners”. The course content includes a study of the material necessary for obtaining skills in using modern ICT and a personal computer using English glossary. Conclusions are drawn regarding conditions and principles of teaching computer science in a foreign language. The scientific novelty of the work is that for the first time a comprehensive analysis of the expediency of using CLIL methodology was carried out at the Kremenchuk Mykhailo Ostrohradskyi National University. The practical significance of the work is that its results can be used for further implementation of content and language integration in Ukraine universities. The development of new content and language integrated courses with CLIL methodology for teaching courses in a foreign language is considered promising.

Published: January 2021

The transformation of classical educational forms in the conditions of step-by-step implementing the Conceptual Principles “New Ukrainian School”, in particular, through using educational material’ visualization is researched. The purpose of the study is to analyze visualization as a methodological technique during mathematics lessons in secondary educational institutions. An empirical study of visualization as a methodological technique for lessons’ effectiveness was carried out by means of an online questionnaire using Google forms service. The purpose of questionnaire was to determine frequency of visualization using in mathematics lessons, positive effects of visualization, as well as to clarify the problems associated with its use. Analysis of the results of the questionnaire indicates that this methodological technique is actively used in the educational activities of Poltava region secondary educational institutions teachers. Due to an analytical prioritization of the positive effects of visualization using in mathematics lessons it’s showed that teachers note time saving and information saturation as the main benefits. Much less priority is given to such advantages as facilitating perception and memorization, as well as interactivity, which are of particular importance for senior students. It is concluded that such characteristics of respondents as the geography of educational institutions where survey participants work, as well as branches (mathematical knowledge groups), which include single parts of mathematics, were irrelevant in the aspect of using visualization as a methodological technique when conducting math lessons. The practical value of the study is due to the fact that its results can be used in lessons on other associated subjects related to didactics and methods of teaching mathematics. The results of monitoring the visualization in mathematics lessons at Poltava region secondary educational institutions can be used in further empirical studies on this field.

Authors: Siebers Teun , Beyens Ine , Pouwels J. Loes , Valkenburg Patti M.
Published: January 2021

A widespread concern in society is that adolescents experience an increased inability to concentrate and sustain attention because they are continuously distracted by social media. The current experience sampling method (ESM) study examined whether adolescents who use more social media than their peers experience more distraction (between-person association), whether social media use (SMU) and distraction co-fluctuate within adolescents (momentary within-person associations), and to what extent this within-person association differs from person to person (person-specific associations). With a sample of 383 adolescents (Mage = 14.11), who together completed 35,099 ESM surveys (73% compliance), we found both a positive between-person association (β = .31) and a positive momentary within-person association (β = .12) of SMU with distraction. The momentary within-person association differed from adolescent to adolescent: While SMU and distraction were positively associated among 82.5% of all adolescents, they were not associated among 15.7% of the adolescents, and negatively associated among 1.8% of the adolescents. Additional analyses on the direction of the effect showed that the within-person effect of SMU on subsequent levels of distraction was somewhat stronger (β = .05) than the effect of distraction on subsequent levels of SMU (β = .03).

Published: January 2021

Introduction: This study is aimed to examine the predominant inflammatory cells in nasal polyps (NP) in the local community and its correlation to the clinical presentations. Materials and Methods: The study was done retrospectively looking at patients who had undergone functional endoscopic sinus surgery (FESS) in Hospital Universiti Sains Malaysia (HUSM), Kelantan, Malaysia with a histopathological diagnosis of nasal polyposis (NP), between the years 2004 to 2008. Sixty-two patients between the ages of 18 years to 60 years old were selected and data relevant to the study were collected from the patient’s folders using a specially created form prepared for the study. The NP histopathology report from each patient underwent FESS were analysed and the patients were divided into eosinophilic and non-eosinophilic dominant group. Clinical presentations from each patient were also gathered and analysed according to the NP group. Results: In HUSM, there were a higher number of eosinophilic types NP as compared to the neutrophilic type NP which is contrary to other study conducted on Asian populations. The clinical symptom correlations between either eosinophilic or non-eosinophilic type of NP have not shown any significant associations. Conclusion: The study showed that the incidence of histological subtypes of nasal polyp in HUSM is almost the same as that found in other parts of the world (Europe and North America) which will reduce the possibility of racial or geographical influence on the pathogenesis of the nasal polyp. Clinical symptoms and presentation alone are not enough to differentiate the type of the nasal polyp without the histological study.

Published: January 2021

Introduction: Edinburgh Postpartum Depression Scale (EPDS) is a tool used to assess the risk of postpartum depression (PPD). In this study we determined the reliability and validity of the Malay version of EPDS when administered at two different time points in the postpartum period. Materials and Methods: This cross-sectional study design was carried out between May and September 2017 at three government primary healthcare clinics located in Batang Padang district, a suburban area of Perak state in Peninsular Malaysia. We recruited a total of 89 women; 41 women were in the early postpartum period (1-30 days) and 48 women were in the late postpartum period (31-120 days). Cronbach's alpha coefficient, inter-item correlation, and corrected item-total correlation were used to assess the internal consistency. The concurrent validity was assessed using Spearman’s correlation. The data were analyzed using SPSS version 20 and R 3.4.2. Results: The Cronbach’s alpha for the first and second group was 0.78 and 0.62, respectively, which indicated satisfactory reliability. At both time periods, removing Item 2 from the scale resulted in a significant increase in Cronbach’s alpha (to 0.847 and 0.709, respectively). As expected, the EPDS scores correlated moderately with the BDI-II scores (1−30 days: Spearman's rho = 0.65, p < 0.01; 31−120 days: Spearman's rho = 0.73, p < 0.01). Conclusion: The Malay version of the EPDS is a reliable screening instrument for detecting postpartum depression. It showed reasonability and feasibility and can be used in postpartum clinical settings or for assessing intervention effects in research studies. Furthermore, as our results indicated, removing Item 2 from the Malay version would increase the internal consistency of the EPDS.

Теория гетерогенного катализа. Теория хемосорбции
Authors: Садовников Василий
Published: January 2021

This monograph is a continuation of the monograph by V.V. Sadovnikov. Lateral interaction. Moscow 2006. Publishing house "Anta-Eco", 2006. ISBN 5-9730-0017-6. In this work, the foundations of the theory of heterogeneous catalysis and the theory of chemisorption are more easily formulated. The book consists of two parts, closely related to each other. These are the theoretical foundations of heterogeneous catalysis and chemisorption. In the theory of heterogeneous catalysis, an experiment is described in detail, which must be carried out in order to isolate the stages of a catalytic reaction, to find the stoichiometry of each of the stages. This experiment is based on the need to obtain the exact value of the specific surface area of the catalyst, the number of centers at which the reaction proceeds, and the output curves of each of the reaction products. The procedures for obtaining this data are described in detail. Equations are proposed and solved that allow calculating the kinetic parameters of the nonequilibrium stage and the thermodynamic parameters of the equilibrium stage. The description of the quantitative theory of chemisorption is based on the description of the motion of an atom along a crystal face. The axioms on which this mathematics should be based are formulated, the mathematical apparatus of the theory is written and the most detailed instructions on how to use it are presented. The first axiom: an atom, moving along the surface, is present only in places with minima of potential energy. The second axiom: the face of an atom is divided into cells, and the position of the atom on the surface of the face is set by one parameter: the cell number. The third axiom: the atom interacts with the surrounding material bodies only at the points of minimum potential energy. The fourth axiom: the solution of the equations is a map of the arrangement of atoms on the surface. The fifth axiom: quantitative equations are based on the concept of a statistically independent particle. The formation energies of these particles and their concentration are calculated by the developed program. The program based on these axioms allows you to simulate and calculate the interaction energies of atoms on any crystal face. The monograph is intended for students, post-graduate students and researchers studying work and working in petrochemistry and oil refining.

Authors: Sumarno Theresia Betty , Bachtiar Andang , Jati Artody Nugroho
Published: January 2021

Indonesia is known as the largest economy in South East Asia and as one of the emerging lower-middle-income countries. Before the pandemic Covid-19, Indonesia forecasted its GDP growth to increase to 5.5% in 2020. However, this never happened following the pandemic it decreased to 2.97% in the first quarter of 2020. This paper focuses on the renewable energy role in accelerating the economic recovery in Indonesia by emphasising the role of justice in the transition process. We conduct systematic reviews from different sources, both primary and secondary resources. We qualitatively analyse the energy regulation and energy road map in Indonesia as well as some academic research articles. Indonesia has developed its general energy plan related to the energy mix demand and supply, which includes a long-term plan on developing renewable energy sources and reducing the use of fossil fuels. As the fourth most populated country in the world, Indonesia still focusses on cheap energy supply and energy access to fulfil the energy demand. Therefore the transition process in Indonesia is considered slow compared to the OECD countries. There is a significant role of energy in economic growth, both energy consumption and energy resources. Until now, fossil fuels have dominated the Indonesian energy supply and demand. This paper highlights the role of renewable energy in the economic development of the country. This paper suggests that the pandemic has highlighted the energy transition movement in Indonesia. The Covid-19 has driven more research on the role of renewable energy project to the economic development and demonstrate that a transition to a low-carbon economy could contribute to the economic recovery in a justice way in many sectors. Renewable energy development contributes directly to human resources development, and this development also contribute to health sector improvement. Finally, this renewable energy development could accelerate the economic recovery in Indonesia and reach 5.2 to 5.6% in 2021.
Force Majeure in Post COVID-19: The Implication for Future Energy Law Contracts
Authors: Nwedu Cosmos Nike , Alo Solomon Amauchechukwu
Published: January 2021

The global uproar of coronavirus disease, codenamed COVID-19, remains one greatest challenge at least in our present time. The energy sector, in particular, has faced economic doom, as prices of crude oil dipped flatly below $0 on Monday, 20 April 2020, due to low demand amid containment lockdown measures of various governments worldwide. More-so, the performance of existing energy contracts, especially time-bound oil and gas supply, has become impracticable. This has resulted in contracting parties invoking force majeure clauses as an excuse. There have arisen divergent views as to whether COVID-19 is an acceptable force majeure, and such unsettled views could arguably impact energy law contracts. This study analytically considers the future implication of force majeure in post-COVID-19 on energy law contracts. The study lends a forward-thinking approach to crafting future energy law contracts.
TRAVERSING SACRED STONES IN THE HEART OF BORNEO: TRANSBOUNDARY ECOTOURISM THROUGH THE MEGALITHIC LANDSCAPES OF THE KELABIT HIGHLANDS OF SARAWAK, MALAYSIA AND THE KERAYAN HIGHLANDS OF KALIMANTAN, INDONESIA
Authors: Hitchner Sarah , Bala Poline
Published: January 2021

The Kelabit Highlands of Sarawak, Malaysia and the Kerayan Highlands of Kalimantan, Indonesia areculturally contiguous areas separated by the Apad Wat mountain range, consisting of a number ofvillages that are related ethnically, linguistically, and through marriage. Though now separated by apolitical boundary, locals have always traversed this border. Now, foreign tourists also walk across thisborder, as community-based transboundary ecotourism is often centered around long-distance trekkingamong villages. The main attractions along the way for most tourists are impressive megaliths thatinclude erected stones, carved stones, and large piles of stones, and other cultural sites such as oldlonghouse sites, and earthworks in various shapes such as crocodiles. These cultural sites, and thelandscape in which they are found, represent a complex history of movement in the landscape by various,but related, ethnic groups that predates political separation. These sites have deep cultural and religioussignificance to local people on both sides of the border, and the experience of trekking among them hassignificance beyond mere tourism for many visitors as well. There is strong local, governmental, andinternational support for ecotourism development here, as well as an awareness of the possible pitfallsof expanding ecotourism in this region. This paper provides background on elements of the landscapeitself, particularly megalithic structures located within intact rain forest, that attract visitors. It alsopresents a synopsis of some of the cross-boundary efforts to simultaneously promote responsible andculturally sensitive ecotourism development and to protect the ecological and cultural integrity of thisunique megalithic landscape in the “heart of Borneo.” Research for this article was conducted primarilyin the Kelabit Highlands, and emphasis on this area is reflected in the data and discussion.

Published: January 2021

This research examine the effect of psychological contract fulfillment on employee outcomes including employee turnover intentions and employee constructive voice behaviors; whereas affective commitment was utilized as a mediator to examine the intensity of its effect on the relationship among psychological contract fulfillment and employee outcomes. The convenience sampling method was used. Data was gathered through onsite administration of a survey from individuals working in banking sector of Pakistan. The Psychological Contract Fulfillment Scale (Conway & Briner, 2002), Affective Commitment Scale (Meyer, Allen, & Smith, 1993), Employee Turnover Intentions Scale (Kuvaas, 2006) and Employee Constructive Voice Behaviors Scale (Van Dyne & Lepine, 1998) were used. The findings depict psychological contract fulfillment had negative relationship with employee’s turnover intention whereas it was positively linked with employee’s constructive voice behaviors. Further results revealed affective commitment significantly mediate relationship between psychological contract fulfillment and employee outcomes such that fulfillment of psychological contract positively contributes towards affective commitment levels among workforce which eventually increases constructive voice behaviors and lower turnover intentions among employees within an organization.

Although it is known that stronger cell-extracellular matrix interactions will be developed as neurons mature, how such change influences their response against traumatic injury remains largely unknown. In this report, by transecting axons with a sharp atomic force microscope tip, we showed that the injury-induced retracting motion of axon can be temporarily arrested by tight NCAM (neural cell adhesion molecule) mediated adhesion patches, leading to a retraction curve decorated with sudden bursts. Interestingly, although the size of adhesion clusters (~0.5–1 μm) was found to be more or less the same in mature and immature neurons (after 7- and 3-days of culturing, respectively), the areal density of such clusters is three times higher in mature axons resulting in a much reduced retraction in response to injury. A physical model was also adopted to explain the observed retraction trajectories which suggested that apparent adhesion energy between axon and the substrate increases from ~0.12 to 0.39 mJ/m2 as neural cell matures, in good agreement with our experiments.

Cell invasion is defined by the capability of cells to migrate across compartment boundaries established by basement membranes (BMs). The development of complex organs involves regulated cell growth and regrouping of different cell types, which are enabled by controlled cell proliferation and cell invasion. Moreover, when a malignant tumor takes control over the body, cancer cells evolve to become invasive, allowing them to spread to distant sites and form metastases. At the core of the switch between proliferation and invasion are changes in cellular morphology driven by remodeling of the cytoskeleton. Proliferative cells utilize their actomyosin network to assemble a contractile ring during cytokinesis, while invasive cells form actin-rich protrusions, called invadopodia that allow them to breach the BMs. Studies of developmental cell invasion as well as of malignant tumors revealed that cell invasion and proliferation are two mutually exclusive states. In particular, anchor cell (AC) invasion during Caenorhabditis elegans larval development is an excellent model to study the transition from cell proliferation to cell invasion under physiological conditions. This mini-review discusses recent insights from the C. elegans AC invasion model into how G1 cell-cycle arrest is coordinated with the activation of the signaling networks required for BM breaching. Many regulators of the proliferation-invasion network are conserved between C. elegans and mammals. Therefore, the worm may provide important clues to better understand cell invasion and metastasis formation in humans.
Primary-Secondary Transition – Building Hopes and Diminishing Fears Through Drama
Authors: Barlow William D.

This case study explores how pupils might address the issues of bullying and friendships during primary-secondary transition through drama conventions. The research was implemented on the west coast of Scotland during the final four weeks of primary education in three associated primary seven classes. Research methods included pupil questionnaires (primary and secondary school), teacher observations, researcher’s diary, semi-structured interviews (teachers) and a focus group (pupils). The data suggest that some pupils conceptualized their primary-secondary transition as ‘moving up’. However, as the drama developed pupils recognized the multiple and multi-dimensional aspects of their transition. In addition, pupil and teachers indicated that when pupils engage with a drama transition curriculum, it supports the promotion of friendships while diminishes fears and provides strategies for those who might encounter bullying.
Altering Antigen Charge to Control Self-Assembly and Processing of Immune Signals During Cancer Vaccination

Biomaterial delivery systems offer unique potential to improve cancer vaccines by offering targeted delivery and modularity to address disease heterogeneity. Here, we develop a simple platform using a conserved human melanoma peptide antigen (Trp2) modified with cationic arginine residues that condenses an anionic toll-like receptor agonist (TLRa), CpG, into polyplex-like nanoparticles. We reasoned that these structures could offer several useful features for immunotherapy – such as tunable loading, co-delivery of immune cues, and cargo protection – while eliminating the need for synthetic polymers or other complicating delivery systems. We demonstrate that Trp2/CpG polyplexes can readily form over a range of Trp2:CpG ratios and improve antigen uptake by primary antigen presenting cells. We show antigen loading can be tuned by interchanging Trp2 peptides with defined charges and numbers of arginine residues. Notably, these polyplexes with greater antigen loading enhance the functionality of Trp-2 specific T cells and in a mouse melanoma model, decrease tumor burden and improve survival. This work highlights opportunities to control the biophysical properties of nanostructured materials built from immune signals to enhance immunotherapy, without the added complexity or background immune effects often associated with synthetic carriers.

The presence of Listeria monocytogenes in Mozzarella di Bufala Campana Protected Designation of Origin cheeses may depend on curd stretching conditions and post contaminations before packaging. To avoid cross-contamination, thermal treatment of water, brines and covering liquid may become necessary. The present study aimed to improve knowledge about L. monocytogenes thermal resistance focusing on the influence of some cheese making operations, namely curd stretching and heat treatment of fluids in contact with cheese after molding, in order to improve the safety of the cheese, optimize efficacy and sustainability of the processes. Moreover, the role that cheese curd stretching plays in L. monocytogenes inactivation was discussed. The 12 tested strains showed a very heterogeneous heat resistance that ranged from 7 to less than 1 Log10 Cfu/mL reduction after 8 min at 60°C. D-values (decimal reduction times) and z-values (thermal resistance constant) calculated for the most heat resistant strain among 60 and 70°C were highly affected by the matrix and, in particular, heat resistance noticeably increased in drained cheese curd. As cheese curd stretching is not an isothermal process, to simulate the overall lethal effect of an industrial process a secondary model was built. The lethal effect of the process was estimated around 4 Log10 reductions. The data provided may be useful for fresh pasta filata cheese producers in determining appropriate processing durations and temperatures for producing safe cheeses.
A Systematic Review and Meta-Analysis of Animal Studies Testing Intra-Arterial Chilled Infusates After Ischemic Stroke

Background: As not all ischemic stroke patients benefit from currently available treatments, there is considerable need for neuroprotective co-therapies. Therapeutic hypothermia is one such co-therapy, but numerous issues have hampered its clinical use (e.g., pneumonia risk with whole-body cooling). Some problems may be avoided with brain-specific methods, such as intra-arterial selective cooling infusion (IA-SCI) into the arteries supplying the ischemic tissue.

Objective: Our research question was about the efficacy of IA-SCI in animal middle cerebral artery occlusion models. We hypothesized that IA-SCI would be beneficial, but translationally-relevant study elements may be missing (e.g., aged animals).

Methods: We completed a systematic review of the PubMed database following the PRISMA guidelines on May 21, 2020 for animal studies that administered IA-SCI in the peri-reperfusion period and assessed infarct volume, behavior (primary meta-analytic endpoints), edema, or blood-brain barrier injury (secondary endpoints). Our search terms included: “focal ischemia” and related terms, “IA-SCI” and related terms, and “animal” and related terms. Nineteen studies met inclusion criteria. We adapted a methodological quality scale from 0 to 12 for experimental design assessment (e.g., use of blinding/randomization, a priori sample size calculations).

Results: Studies were relatively homogenous (e.g., all studies used young, healthy animals). Some experimental design elements, such as blinding, were common whereas others, such as sample size calculations, were infrequent (median methodological quality score: 5; range: 2–7). Our analyses revealed that IA-SCI provides benefit on all endpoints (mean normalized infarct volume reduction = 23.67%; 95% CI: 19.21–28.12; mean normalized behavioral improvement = 35.56%; 95% CI: 25.91–45.20; mean standardized edema reduction = 0.95; 95% CI: 0.56–1.34). Unfortunately, blood-brain barrier assessments were uncommon and could not be analyzed. However, there was substantial statistical heterogeneity and relatively few studies. Therefore, exploration of heterogeneity via meta-regression using saline infusion parameters, study quality, and ischemic duration was inconclusive.

Conclusion: Despite convincing evidence of benefit in ischemic stroke models, additional studies are required to determine the scope of benefit, especially when considering additional elements (e.g., dosing characteristics). As there is interest in using this treatment alongside current ischemic stroke therapies, more relevant animal studies will be critical to inform patient studies.

For epileptic patients requiring resective surgery, a modality called stereo-electroencephalography (SEEG) may be used to monitor the patient's brain signals to help identify epileptogenic regions that generate and propagate seizures. SEEG involves the insertion of multiple depth electrodes into the patient's brain, each with 10 or more recording contacts along its length. However, a significant fraction (≈ 30% or more) of the contacts typically reside in white matter or other areas of the brain which can not be epileptogenic themselves. Thus, an important step in the analysis of SEEG recordings is distinguishing between electrode contacts which reside in gray matter vs. those that do not. MRI images overlaid with CT scans are currently used for this task, but they take significant amounts of time to manually annotate, and even then it may be difficult to determine the status of some contacts. In this paper we present a fast, automated method for classifying contacts in gray vs. white matter based only on the recorded signal and relative contact depth. We observe that bipolar referenced contacts in white matter have less power in all frequencies below 150 Hz than contacts in gray matter, which we use in a Bayesian classifier to attain an average area under the receiver operating characteristic curve of 0.85 ± 0.079 (SD) across 29 patients. Because our method gives a probability for each contact rather than a hard labeling, and uses a feature of the recorded signal that has direct clinical relevance, it can be useful to supplement decision-making on difficult to classify contacts or as a rapid, first-pass filter when choosing subsets of contacts from which to save recordings.
