Comparative Analysis of Macroeconomic Indicators of the EU and the USA
Authors: Kuzmina V. M. , Parkhomchuk M. A.
Published: June 2022

Relevance. At the beginning of the second decade of the XXI century. economic relations between the United States and the European Union continue to largely determine the development trends of the global economy and the world financial system. The stable dynamics of the transatlantic flows of goods, services and capital reflects the traditional proximity of the models of economic development of the United States and Western Europe, the stability of the existing ties, and the high effective demand of both regions for modern goods and services.

The purpose is to carry out a comparative analysis of the macroeconomic indicators of the development of the EU countries and the USA.

Objectives: consider the dynamics of the main macroeconomic indicators of the EU and the US from 2015 to 2020; to study and visualize the dynamics of GDP growth, GDP in PPP per capita, inflation in the EU member states for 2016–2020; investigate the dynamics of the total US government debt for 2015-2020.

Methods. The method of statistical analysis of data from official government websites (European Parliament) and world agencies - Organization for Economic Cooperation and Development (OECD), Global-finances. The method of comparative analysis was used to compare real GDP, nominal GDP, GDP per capita, dynamics of changes in GDP EU countries and the USA in relation to previous years.

Results. If we compare the development of the EU and the United States in terms of the main macroeconomic indicators, we can conclude that the countries have experienced periods of recession and stagnation in economic development to the same extent, including those associated with a lockdown and economic crises against the backdrop of a pandemic. However, in 2020, the countries showed a positive trend towards a reduction in negative GDP, including GDP in PPP per capita. The situation is more complicated in the United States, in terms of the size of the national debt.

Conclusions. In modern conditions, the United States and the EU are still not only the main economic partners, but also the main competitors at the global level. The United States plays a leading role in international economic relations, but the United States has the largest trade deficit with China and the EU countries, therefore, in recent years, the idea of creating a free trade zone between the United States and the EU has been most actively supported (among business structures).

Authors: Shmanev S. V.
Published: June 2022

Relevance. Modern Russia is a succession of transformations of the national economy. The reforms carried out in the country affect the issues of social, scientific, scientific-technical (including the modernization of higher education), and general economic nature.

The key mechanism for transforming Russia's economy is national projects, based on a series of documents developed and adopted by the government between 2002 and 2011. All ongoing transformations are based primarily on the development of human capital; systems related to education, health care; transformation of infrastructure; modernization of industry and public administration. The success of such transformations can be ensured by the state policy aimed at increasing the competitive advantages of the Russian economy in the field, science, and digitalization of the economy.

Purpose. To analyze the current state of the Russian economy under the conditions of digital transformation and give recommendations for improving the mechanisms of macroeconomic regulation of the accelerated development of the Russian economy based on proactive industrial policy.

Objectives. To substantiate the conceptual directions of the breakthrough development of industry in the Russian Federation in the strategic perspective, as the basis for sustainable socio-economic development of the country in the context of digitalization.

Methodology. The study used methods of comparative analysis, economic-statistical and methods of expert evaluations.

Results. The industrial complex, based on advanced technologies, is not only an indicator of the pace and efficiency of knowledge-intensive production, stabilizer of socio-economic processes but also serves as a guarantor of the national sovereignty of the country.

Conclusions. The state socio-economic policy aimed at the introduction of advanced technologies affects not only the high-tech sector of the economy but also traditional industries. This policy will make it possible to transform the institutions of economic development and modernize existing business models, as well as to create conditions for improving the ongoing industrial policy.

Published: June 2022

Background

The implementation of eMental health interventions, especially in the workplace, is a complex process. Therefore, learning from existing implementation strategies is imperative to ensure improvements in the adoption, development, and scalability of occupational eMental health (OeMH) interventions. However, the implementation strategies used for these interventions are often undocumented or inadequately reported and have not been systematically gathered across implementations in a way that can serve as a much-needed guide for researchers.

Objective

The objective of this scoping review was to identify implementation strategies relevant to the uptake of OeMH interventions that target employees and detail the associated barriers and facilitation measures.

Methods

A scoping review was conducted. The descriptive synthesis was guided by the RE-AIM (reach, effectiveness, adoption, implementation, and maintenance) framework and the Consolidated Framework for Implementation Research.

Results

A total of 31 of 32,916 (0.09%) publications reporting the use of the web-, smartphone-, telephone-, and email-based OeMH interventions were included. In all, 98 implementation strategies, 114 barriers, and 131 facilitators were identified. The synthesis of barriers and facilitators produced 19 facilitation measures that provide initial recommendations for improving the implementation of OeMH interventions.

Conclusions

This scoping review represents one of the first steps in a research agenda aimed at improving the implementation of OeMH interventions by systematically selecting, shaping, evaluating, and reporting implementation strategies. There is a dire need for improved reporting of implementation strategies and combining common implementation frameworks with more technology-centric implementation frameworks to fully capture the complexities of eHealth implementation. Future research should investigate a wider range of common implementation outcomes for OeMH interventions that also focus on a wider set of common mental health problems in the workplace. This scoping review’s findings can be critically leveraged by discerning decision-makers to improve the reach, effectiveness, adoption, implementation, and maintenance of OeMH interventions.
Opportunity for a Virtual Mental Health Crisis Ward: Early Learning from a Low-Resource COVID-Response Initiative (Preprint)
Authors: Lee Katherine , Bolton Shay-Lee , Shterenberg Ravit , Bolton James , Hensel Jennifer
Published: June 2022

BACKGROUND

The COVID-19 pandemic saw the accelerated uptake of virtual care and a proliferation of virtual ward models as alternatives to facility-based care. Early in the pandemic, our program implemented a virtual mental health crisis ward (vWard) to provide options for individuals needing intense psychiatric and/or crisis support but who preferred to remain in community and were safe to do so.

OBJECTIVE

This study aimed to identify early learnings from the vWard implemented rapidly in a resource constrained environment, to inform the future state should it be sustained beyond the pandemic.

METHODS

Mixed methods of data collection were used to evaluate provider perspectives on the vWard, develop archetypes for individuals who are a good fit for the vWard model, and create a driver diagram. Data sources included an anonymous survey of clinical and managerial staff involved in the vWard, a service planning workshop, and analysis of program discharge forms for all individuals admitted between March 2020 and April 2021. Survey responses were coded for themes under categories of “Benefits” and “Challenges.” Discharge forms where the team indicated that the vWard was a good fit for an individual, were examined for characteristics common to these admissions. These findings were reviewed in the service planning workshop and refined with input from the participants into patient archetypes. A driver diagram was created for the future state.

RESULTS

Survey respondents (N=60) represented diverse roles in crisis services and the vWard team. Ten providers took part in the service planning workshop. A total of 467 discharge forms were reviewed. The vWard was felt to be a model that worked by 39 survey respondents, 1 felt it did not work, and the remaining had no response. A number of benefits for the individual and the system were identified, alongside challenges – some process and material related to the nature of rapid implementation during the pandemic, and others due to lack of fit for certain individuals. The model was felt to a good fit for 67.5% of admissions. Four patient archetypes representing good fit with the model were developed. The driver diagram connected the program aim with primary drivers – (1) reduce barriers to care, (2) improve outcomes, and (3) provide collaborative, patient- and family-centered care – linked to secondary drivers and interventions that leveraged virtual technology among other crisis care interventions.

CONCLUSIONS

Despite some challenges, the vWard demonstrated high levels of provider acceptance and a range of mechanisms by which the model works for a variety of patient archetypes. These early learnings provide a foundation for growth, sustainability and spread going forward beyond the pandemic.
Performance Evaluation of Extracting Medical Information from Patient Notes using Natural Language Processing Methods (Preprint)
Authors: Sezgin Emre , Hussain Syed-Amad , Rust Steve , Huang Yungui
Published: June 2022

UNSTRUCTURED

Patient-generated health data (PGHD) is becoming a necessary component of remote monitoring and clinical decision-making as well as self-care and managing chronic conditions. Medical diaries and patient notes have been the primary source of unstructured PGHD, enabling patients to collect and communicate their health information remotely and in real-time to their providers. Yet there is no established mechanism or pipeline for processing free text patient notes (“unstructured PGHD”) or integrating these notes into clinical decision making in a low-resource setting (i.e., not depending on a large dataset or processing power). In the literature, there are a number of studies reporting NLP applications on clinical notes to identify symptoms and conditions, but these studies have been limited to public data (e.g. social media posts by patients). In this paper, we evaluate the performance of an hybrid (deep learning + rule-based) NLP pipeline on a low-resource PHGD dataset through an empirical evaluation of automatic component extraction where we measure the model’s ability to conduct automatic entity extraction using ontologies (medication-dose: RxNORM, symptoms: SNOMED) from patient notes.

Authors: Joshi Ashish , Surapaneni Krishna Mohan , Grover Ashoo , Kaur Harpreet , Saggu Sofia , Oliveira Doilyn
Published: June 2022

BACKGROUND

Non-communicable diseases (NCDs) likely require a longer period of care, for which healthcare systems must acquire technologically advanced solutions to enhance patient care. Swasthya Pahal (health for all) is an innovative, interactive, multilingual, standalone, and internet-enabled computer-based program that aims to improve the self-management of NCDs.

OBJECTIVE

The objective of the study is to determine the usefulness, acceptance, and effectiveness of the Swasthya Pahal program in hospital and community settings in both rural and urban areas of Chennai, Tamil Nadu. This objective can be met by generating risk factor profiles of individuals enrolled and enhancing their self-management of NCDs using a portable health information kiosk that employs the SMAARTTMmodel.

METHODS

A quantitative study will be conducted on a convenient sample of 2800 individuals from the selected hospital and community settings in rural (n=1400) and urban areas (n=1400) in Chennai, Tamil Nadu. Data will be collected on socio-demographics, health behaviors, clinical status and Knowledge, Attitude, and Practices. Objective assessments such as weight, blood pressure, and random blood sugar levels will be measured. Additionally, the usefulness, acceptance, and effectiveness of the Swasthya Pahal program will be determined.

RESULTS

Results will be summarized using descriptive analysis. Appropriate bivariate and multivariate regression analysis will be performed to determine the predictors of the outcome variables of usefulness, acceptance, and effectiveness of Swasthya Pahal in wider settings. All analyses will be performed using SAS v9.1 and reporting of the results done at 95% CI and p<0.05.

CONCLUSIONS

The proposed study will help enhance the self-management of NCDs in both rural and urban community settings by the implementation of the Swasthya pahal program based on the SMAARTTM informatics framework.
Tracking openness and topic evolution of COVID-19 publications: a comprehensive analysis (January 2020- March 2021) (Preprint)
Authors: San Torcuato Maider , Bautista-Puig Núria , Arrizabalaga Olatz , Méndez Eva
Published: June 2022

BACKGROUND

The COVID-19 outbreak showed the importance of rapid access to research.

OBJECTIVE

This paper investigates research communication about this disease, the level of openness of papers, and the main topics of research into this disease.

METHODS

Thus, it analyses Open Access (OA) uptake (typologies, licence use) and the topic evolution of publications, from the start of the pandemic (1 January 2020) until the end of a year of widespread lockdown (1 March 2021).

RESULTS

The sample includes 95,605 publications; 94.1% were published for open access, 44% of them in Bronze OA. 42% do not have a licence, which can limit the number of citations, and thus impact. We also illustrated an approach that uses a topic modelling method and found that publications in Hybrid and Green OA publications are more focused on patients and their effects whereas the strategy adopted by countries is studied more in papers that have chosen the Gold OA route.

CONCLUSIONS

The study concludes that although OA scientific production has increased, some weaknesses in Open Access practise, such as lack of licensing or under-researched topics, still hold back its effective use to further research.
Structure of a quotient ring R/P and its relation with generalized derivations of R
Authors: Bouchannafa Karim , Mamouni Abdellah , Oukhtite Lahcen
Published: June 2022

The fundamental aim of this paper is to investigate the structure of a quotient ring R/P where R is an arbitrary ring and P is a prime ideal of R. More precisely, we will characterize the commutativity of R/P via the behavior of generalized derivations of R satisfying algebraic identities involving the prime ideal P. Moreover, various wellknown results characterizing the commutativity of prime (semi-prime) rings have been extended. Furthermore, examples are given to prove that the restrictions imposed on the hypothesis of the various theorems were not superfluous.
Studying the Penetration Ability of Various Pathogenic Bacteria into Raw Beef Meat Surface and the Antibacterial Effect of Ozonated Water
Authors: Ali May Mohammed , Al-Mousawi Masar R. , Aljabawi Rasha A. Abidalmutalib
Published: June 2022

Colonization of meat with bacterial pathogens potentially affects the quality of the meat products. This study aimed to determine the penetration ability of psychrotolerant bacterial pathogens into the surface of red beef meat. The penetration experiment was carried out on raw beef meat to see how different time intervals (1 day, 2 days, and 3 days) and temperatures (5°C, 15°C, and 20°C) affected the penetration process. When bacteria are found at a depth of about 2 cm in the tested meat block, this is considered a positive penetration occurrence. In this study, the action of ozone treatment (at variable exposition times) on the bacterial loads of beef meat samples in which bacterial penetration occurred was evaluated. The formation of ozone was accomplished by utilizing an O3 generator (A2Z/AQUA-6, USA). The O3(ppm) concentration in water was defined using the HI 38054 Ozone Test Kit (Hanna Instrument®, USA). The results of bacterial penetrability suggest that at low temperatures, the rate of germ penetration onto the meat surface decreases. The results revealed that the penetration rate increased in the case of dual and triple bacterial species. This can be explained by the fact that all the bacterial species that were used in the study are actively motile and have proteolytic activity. These proprieties together absolutely play a major role in the acceleration of the penetration process by these bacteria, or even so, their existence together is synergistic for migration deeper into meat. To ensure freshness and public health protection, raw meat must be treated and processed in a sanitary manner. Under the conditions used in this study, a concentration of 0.5 ppm of O3 was found to be highly effective in reducing the bacterial count in meat blocks. This decline was aided by rising the exposing time to 45 minutes to achieve 3 log10 CFU/ml-1, and the bacterial count diminished with increased exposure time to ozonated water at the same concentration. These results suggest that O3 treatment could be used to lay the groundwork for a new method of reducing meat contamination by foodborne bacterial pathogens.

Published: June 2022

This study examined 150 ear swab samples from patients with otitis media who consulted at Al-Sadr Teaching Hospital from January to April 2021 in Misan, Iraq. The participants were aged 14–50 years, among which the infection rate was highest in participants aged 14–22 years and lowest in those aged 40–50 years. Subsequently, bacterial isolates were identified based on their morphology in various culture media and using biochemical tests. Six bacterial species were identified, namely Pseudomonas aeruginosa, Staphylococcus aureus, Escherichia coli, Streptococcus pneumoniae, Klebsiella pneumoniae, and Staphylococcus epidermidis. Staphylococcus aureus had the highest infection rate (30%), whereas Staphylococcus epidermidis had the lowest infection rate (8.55%). When the sensitivity of each isolate to antibiotics was determined, Escherichia coli was the most sensitive to trimethoprim (TMP), whereas Pseudomonas aeruginosa was the most resistant to 75% of the tested antibiotics.

Direct and indirect genetic effects of a social supergene
Authors: Arsenault Samuel , Grognuz Oksana Riba , Shoemaker DeWayne , Hunt Brendan , Keller Laurent
Published: June 2022

Indirect genetic effects, where phenotypic variation is influenced by
the genotypes of social partners, act as heritable sources of
environmental variation in eusocial organisms. In the fire ant
Solenopsis invicta, a supergene exhibits striking indirect genetic
effects on worker regulation of colony queen number. We assess the
direct and indirect genetic effects of this social supergene on gene
expression using RNA-seq of brains and abdominal tissues from lab-reared
workers and field-collected pre-reproductive queens. We find that direct
genetic effects cause larger gene expression changes and are more
consistent across tissue types and castes than indirect genetic effects.
Indirect genetic effects influence the expression of many loci but are
generally restricted to the abdominal tissues. Further, indirect genetic
effects were only detected when the genotypic composition of social
partners differed throughout the development and adult life of the focal
individual, and were often only significant with relatively lenient
statistical cutoffs. Our study demonstrates the importance of including
diverse sample types and considering the magnitude of changes in gene
expression when studying the roles of direct and indirect genetic
effects on behavior.
Exploring the Potential Impact of Relationship Characteristics and Customer Attributes on the Outcomes of Third-party Logistics Arrangements
Authors: KNEMEYER A. MICHAEL , MURPHY PAUL R.
Published: June 2022

This article uses a relationship marketing perspective as the basis for evaluating third-party logistics arrangements. In particular, the study investigates whether 3PL relationship outcomes (e.g., customer retention, service recovery) are influenced by select relationship characteristics (e.g., communication, reputation) and/or select customer attributes (e.g., firm size, number of outsourced logistics functions). The article reports the findings from a study of 388 users of third-party logistics services that investigated these potential linkages. Regression analyses were applied to the constructs of interest in order to learn about the degree of influence. The findings suggest that “substance trumps style” in the sense that relationship characteristics, rather than customer attributes, have the more significant impacts on relationship outcomes.

Authors: ASHENBAUM BRYAN , MALTZ ARNOLD , RABINOVICH ELLIOT
Published: June 2022

This article evaluates the various longitudinal studies of third-party logistics (3PL) usage and proposes methods and approaches to improve the rigor of future research in this area. Three well-established methodologies for combining the results of multiple studies are reviewed (literature reviews, meta-analysis, and repeated survey analysis), and then considered in application to the findings of the various 3PL usage studies since 1991. Beginning with an overview of the results that emerge from simply combining and comparing the key longitudinal data, the article moves on to a more detailed analysis of the measurement scales, data collection methods, and samples utilized in the different 3PL surveys. The article ends with concrete recommendations for reorienting the ongoing surveys to increase their rigor and validity, and thus increase their predictive value to both academics and logistics managers.
Interfirm Linkages and the Structure and Evolution of the Danish Trucking Industry
Authors: SORNN-FRIESE HENRIK
Published: June 2022

Studies of structure and evolution in the European trucking industry have, possibly mistakenly, predicted the shakeout of small motor carriers and argued that only large carriers will be able to create value to shippers in the long run. This prediction is based on an essentially taken-for-granted premise that in the economic theory of industry evolution, the industry life cycle approach applies to the trucking industry. This article argues that it does, in fact, not apply well to this industry, which possesses characteristics that allow for quite different competitive dynamics. The argument is illustrated empirically by a case study of the Danish trucking industry in the 1990s. The study reveals that the Danish trucking industry moves towards increasingly organized markets with a few large carriers, some specialized and flexible small and medium-sized (SME) carriers with vertical and horizontal linkages, and many small carriers and independent owner-operators serving shippers and other carriers on a short-term basis. Adopting a knowledge-based perspective, the persistent coexistence of small, medium-sized, and large carriers can be attributed to the nature and dynamics of demand, the division of labor between different motor carriers, and changes in productive resources.
Bioactive glass granules versus standard autologous and allogeneic bone grafts: a randomized trial of 49 adult bone tumor patients with a 10-year follow-up

Published: June 2022

Background and purpose: As a synthetic bone void filler, bioactive glasses (BGs) may enhance angiogenesis and osteogenesis. In this randomized trial, we compared the clinical efficacy of BG granules and standard bone grafts in patients undergoing surgery for benign bone tumors.Patients and methods: 49 recruited patients were randomized to receive BG granules or undergo conventional bone grafting to fill defects following tumor removal. As the standard of care, small-sized defects were filled with autologous graft, and large-sized defects were filled with allogeneic graft. The primary endpoint was treatment success at 1 year, defined by no reoperation, no tumor recurrence, and no device-related adverse events. Secondary endpoints included patient-reported outcomes (Rand-36 and pain scores) and quantitative assessment of blood flow and metabolic activity by means of 18F-fluoride PET/CT imaging. As an off-trial group, 15 children and adolescents (age < 18 years) underwent tumor removal and BG-filling, without randomization.Results: At 1-year, 21 of 25 BG-treated patients (risk estimate 0.84, 95% confidence interval [CI] 0.70–0.98) and 20 of 24 patients in the standard of care group (0.83, CI 0.68–0.98) met the criteria for treatment success. The groups had similar Rand-36 scores. In patients with small defects, BG filling was associated with shorter operative time and less postoperative pain at 1 month. In patients with large defects, blood flow was similar, but BG-filled defects showed higher metabolic activity than allograft-filled defects at 1-year. The survey of the postoperative period ≥10 years revealed no BG-related adverse events.Interpretation: BG granules had similar overall rates of treatment success compared with autografts and allografts, but large-scale trials are needed for the confirmation of clinical equivalence. The extended metabolic activity confirms the expected cellular responses of osseointegrated BG granules.

Published: June 2022

This study investigated the effect of immediate versus delayed photo-activation on the bonding performance and water uptake of self-adhesive (SA) resin cements under simulated pulpal pressure (SPP). The occlusal dentin surface was exposed in 66 extracted third molars. Resin composite cylinders were cemented to dentin under SPP, with either RelyX Unicem 2 (RU) (3M Oral Care, St Paul, MN, USA) or Maxcem Elite (MC) (Kerr, Orange, CA, USA). Each cement group was equally divided into three groups (n=8 each) according to the time elapsed between placement and photo-activation: immediate activation (IM), 30-second delayed activation (D30), or 120-second delayed activation (D120). Shear bond strength (SBS) was measured, and the type of failure was determined using a stereomicroscope. Three additional samples from each experimental subgroup were used for confocal laser scanning microscopy (CLSM) analysis. A fluorescent dye solution was added to the pulpal fluid reservoir, then a CLSM was used to detect the dye distribution within the tooth-restoration interface. Two-way analysis of variance (ANOVA) and the Tukey post-hoc test were used to analyze the SBS results (α=0.05). D30 resulted in a significantly higher mean SBS in the two cement groups than IM and D120 (p<0.05). RU showed significantly higher SBS values than MC regardless of the time of light activation (p<0.05). RU showed less dye uptake confined to the cement-dentin interface compared to the MC groups, which showed dye uptake throughout the entire thickness of the cement layer and gap formation at the interface, especially in the D120 group. The 30-second photo-activation delay group significantly improved the bond strength of SA cements. Delaying the photo-activation to 120 seconds increased pulpal fluid uptake by SA cements and compromised the integrity of the bonded interfaces.
SCREENING OF ACTINOMYCETES FROM Cystoseira barbata (Stackhouse) C. Agardh COMPOST FOR THEIR ENZYME AND ANTIBACTERIAL ACTIVITIES
Authors: TOPATAN Zeynep Şule , KATI Hatice
Published: June 2022

Bacterial secondary metabolites play an essential role in biotechnological and biomedical applications. Actinomycetes are important bacterial sources of antibiotics and enzymes. Most of the antimicrobials known today have been isolated from actinomycetes, especially from the genus Streptomyces. In this study, actinomycete isolation was performed from Cystoseira barbata (Stackhouse) C. Agardh compost, collected from the Black Sea coast, by serial dilution method. A total of 73 actinomycetes isolates (BSC) were obtained from the compost samples. The ability of the isolates to produce different extracellular enzymes was investigated qualitatively. It was determined that 68.5% of the isolates have amylase, 100% cellulase, 47.9% chitinase, 94.5% pectinase, 98.6% protease and 96.3% lipase/esterase activity. Antibacterial activities of the isolates were investigated primarily using cross-streak method. Isolates showed high antibacterial activities, with 98.6 and 84.9 % against Staphylococcus aureus Rosenbach and Enterococcus faecalis (Andrewes & Horder) Schleifer & Kilpper-Bäl, respectively. Three out of six isolates (BSC-13, BSC-17, BSC-37, BSC-38, BSC-45, BSC-49) with high antibacterial activity, were screened secondarily for their antibacterial activities using double-layer method. At day 7, BSC-37 isolate showed a high inhibition (57 mm) against S. aureus. Furthermore, these six isolates were identified according to their morphological and physiological characteristics and 16S rDNA sequence analysis. 16S rDNA sequence analysis showed that the isolates with high antibacterial activity belong to Streptomyces genus. Results indicated that these isolates have great potential and may serve as a good source for the studies on bioactive natural products.

Authors: Ahmad Syafri -
Published: June 2022

This research is based on the learning background that is still a teacher-centered dynamic while students are passive. The purpose of this research is to develop a teacher’s guideline in learning geometry with the Indonesian Realistic Mathematics Education (PMRI) approach that is valid, practical, and influential. This research is a development research (R&D) with the Tjeerd Plomp model. Field trial with an experimental design of one group pre-test and post-test time series, with a sample of 33 elementary school students in the city of Padang. The results showed that the PMRI teacher guidelines were valid, practical, and influential. In particular, there are significant differences in the geometry learning outcomes between before and after using this teacher guide. This is indicated by the results of the data analysis of the significant difference between post-test 1 and pre-test 1, post-test 2 and pre-test 2, as well as post-test 3 and pre-test 3 with a p-value of 0.001 < 0.05. Qualitatively, students can understand that a square is a rectangle whose all sides are the same length, and that a square and a rectangle had the characteristics of a parallelogram. In term of van Hiele's theory, students are at the stage of informal deductive thinking. Students can conclude the shapes and characteristics of flat shapes of triangles, squares, rectangles, and parallelograms. Elementary school teachers are advised in learning geometry to use the teacher’s guidelines that have been developed.Keywords: Learning, geometry, PMRI, van Hiele, primary school.

The Effect of Biogas Composition on the Characteristics of the Combustion Process
Authors: Leonov Evgeny , Trubaev Pavel
Published: June 2022

Biogas can serve as a substitute for natural fuel, but its use is associated with a number of features associated with the difference in its composition from natural gas. Landfill gas generated in the body of MSW landfills is characterized by a significant change in composition. The purpose of the work was a theoretical study of the effect of changing the composition of biogas and the coefficient of excess air on the parameters of the combustion process - gas and air consumption, combustion temperature and on the volume of combustion products. The influence of the ratio of CO2 and N2 contained in biogas on the main combustion characteristics was also evaluated. It is concluded that the combustion of biogas of variable composition, subject to ensuring the specified heat output of the furnace or boiler, does not require a change in air flow, but only a change in the flow of biogas depending on the content of methane in it. Reducing the content of methane leads to an increase in the volume of exhaust gases and a decrease in their temperature. Therefore, a decrease in the methane content in biogas can lead to a decrease in the intensity of heat exchange and a decrease in the efficiency of the unit. The ratio of CO2 and N2 practically does not affect the thermal parameters of combustion. The results of the study are necessary when designing equipment and determining the operating mode of equipment that burns biogas that is formed in natural conditions, for example, landfill gas generated at HSW landfill.
The Impact of Urban Infill: A Study of Contemporary Malls in Baghdad
Authors: Muhkaber Alomare Ashwaq Fadhel , AL-Musawi Tahrir Taki Ali
Published: June 2022

The impact of urban infill has been an important topic within urban research. Despite the vast knowledge, however, there is a gap in reporting the effect of adding contemporary malls to Baghdad urban context; therefore, we studied two main contemporary malls built after 2003, Al-Mansour Mall in Al-Mansour district and Baghdad Mall in Harthiya district, selected for this study because of their large-scale and their contribution to the development growth of the city. The findings of this research showed they both have a strong impact on different aspects such as urban, social, economic, and the environment. The paper also highlights critical views concerning the spread of malls in Baghdad and discusses the importance of traditional suqs and the reasons of transition to the contemporary malls with suggestions for improvement. This paper contributes to the urban literature by developing a theoretical framework of urban infill indicators. Findings may have implications for future infill developments both for architecture and urban design strategies for city growth.
Structural Behavior of Reinforced Lightweight Concrete Slabs
Authors: M. Hameed Yahyia , Murtada A. Ismael
Published: June 2022

This paper presents an exploration of choosing the optimum density for concrete that achieves the best structural performance for two-way slabs made of concrete with fine aggregate in different proportions less than the ratio used in ordinary concrete to produce different densities, by taking advantage of the idea of fine aggregate concrete which considers as light-weight concrete to achieve lighter concrete with higher structural endurance. The experimental program includes constructing and testing five slabs, four of them made of concrete with different fine aggregate radios 75%, 50%, 25%, and 0% to get different densities (2207, 1792, 1536, 1310 kg/m3) as well as another slab made of normal concrete used as a reference slab with a density of 2414 kg/m3. The outcomes reveal that decreasing the density of the slab from 2414 kg/m3 to 1310 kg/m3 by reduction fine aggregate in concrete from 100% to 0% respectively has more effect on the first crack load than that on the ultimate load of two-way slabs as the first crack load decreases with percentages 16.7%, 33.3%, 38.9%, and 61.1% the while the ultimate load decreases with percentages 7.3%, 21.9%, 46.3%, and 56.1%, respectively as compared to the reference (normal wight concrete slab). Also, decreasing the density of the slab made the cracks form and spread quickly and the slab failure tends towards the brittleness, and the cracks diffused and grew faster and wider.
Estrategias cognitivas para afrontar situaciones de acoso/ciberacoso: diferencias entre chicos y chicas
Authors: Chamizo-Nieto M. Teresa , Rey Lourdes
Published: June 2022

La violencia entre iguales provoca un impacto negativo sobre la salud de los adolescentes implicados. Entre los factores que han mostrado evidencias para predecir la realización y el sufrimiento de conductas agresivas, se encuentran las estrategias de afrontamiento cognitivo-emocional. Sin embargo, en contextos de acoso y ciberacoso pocos estudios han analizado el papel de estas estrategias y, aún menos, de manera separada para chicos y chicas. Por ello, este estudio planteó dos objetivos: analizar las diferencias por sexo en agresión y victimización en acoso y ciberacoso, así como en el uso de las estrategias de afrontamiento; y explorar cuáles son las estrategias que mejor predicen la victimización y agresión en ambas situaciones de manera separada para chicos y chicas. Una muestra de 1904 adolescentes completó tres cuestionarios que evaluaban el acoso, el ciberacoso y las estrategias de afrontamiento cognitivo. Los resultados mostraron diferencias significativas por sexo en agresión, victimización, ciberagresión y en cinco estrategias. Además, los resultados de las regresiones indicaron que, por ejemplo, la estrategia de culpar a otros fue una de las que mejor predijo la agresión y victimización en acoso y ciberacoso en chicos y chicas. Por último, se discuten las limitaciones e implicaciones derivadas de este estudio.
