Estimation of Missing Left Turning Movement For Intersections Traffic Volume Count
Authors: Hummody Mohammad Ahmad
Published: July 2022

Intersection traffic volume count must be in of the accurate data, because it is a crucial in the calibration and validation of traffic demand models. It is process in a continuous manner done by the analyst, planner or designer. Many procedures were recently produced to estimate the intersection turning movement matrix. Sometimes, these procedures of traffic volume count may have unusual, unavailable or missing values especially for the left turn movement, which is more effective in capacity analysis. Typical four mathematical and statistical methods of estimating the missing left turn movement volume were developed for about twenty signalized intersections. The most significant one is the typical curve estimation method. It is a power curve and in a simple formula compared with several other imputation techniques. This method can be superior to substitute the other methods in estimating the intersection traffic volume matrices.

This study aims to determine the credit portfolio strategy (focus or diversification strategy) based on the economic sector in conventional commercial banks grouped by business activity (BUKU) in the period January 2016 - December 2018 and analyze the effect of credit portfolio concentration and credit risk on rates of return. This study uses secondary data obtained from Indonesian Banking Statistics at the Financial Services Authority (OJK). This study used 4 samples, namely BUKU I, BUKU II, BUKU III, BUKU IV.  Bank return as dependent variable was measured by Return on Assets (ROA) whereas Concentration of Credit Portfolio as independent variable was measured by the Herfindahl-Hirschman Index (HHI). The mediating variable (Credit Risk) was measured by Non-Performing Loans (NPL). This study used panel data regression with fixed effect model to test direct effects and Sobel Test to test indirect effect. The results showed that the concentration of the credit portfolio had a positive effect on credit risk, while credit risk had a negative effect on return. In addition, the mediating role of the credit risk variable is not proven to affect the effect of the credit portfolio and credit risk. In conclusion, the credit portfolio concentration strategy in certain sector can increase credit risk so that it tends to reduce the rate of return. Thus, this research suggests that banks need to diversify their credit portfolios to minimize credit risk.an risiko kredit.

Objetivo: Fornecer através de uma revisão narrativa uma ampla abordagem sobre a Síndrome Inflamatória Multissistêmica Pediátrica (SIM-P) como complicação da Covid-19 em crianças e adolescentes. Revisão bibliográfica: A SIM-P se trata de uma síndrome pós-infecciosa, que pode acontecer até cerca de 4 semanas após a infecção aguda pelo novo coronavírus. Na maioria dos casos resulta em um quadro grave com acometimento de diversos órgãos como pulmão, cérebro, coração, rins e outros. Essa condição clínica apresenta semelhança com a Doença de Kawasaki (DK), Síndrome de Ativação Macrofágica e à Síndrome do Choque Tóxico (SCT) e devido à similaridade do quadro da SIM-P com doenças já conhecidas, foi possível um manejo mais adequado dos pacientes, uma vez que ainda existem poucos estudos a respeito do tratamento da síndrome. Considerações finais: A detecção precoce dos casos de SIM-P e instituição de tratamento adequado em tempo hábil é fundamental para evitar complicações graves como choque e alterações cardiovasculares, reduzindo dessa forma o número de óbitos por essa condição.

Evaluation of the reaction mechanism between 1,4-dihydropyridines and α,β-unsaturated nitriles.
Authors: Saez David Adrian , Vogt-Geisse Stefan , Vöhringer-Martinez Esteban
Published: July 2022

Hydride transfer reactions involving 1,4-dihydropyridines play a central role in bioorganic chemistry as they represent an important share of redox metabolism. For this class of reactions, the direct hydrid transfer is the commonly accepted mechanism, however an Alder-Ene-like pathway has been proposed as a plausible alternative. The reaction between 1,4-ditrimethylsilyl-1,4-dihydropyridine, and α,β-unsaturated nitriles is a solid candidate for this latter pathway. In this work, we perform high level ab initio and density functional theory computations to characterize the mechanism of this reaction, taking into account diverse reaction paths, evaluating the effect of solvent polarity and variations in chemical structure. Our analysis explains the stereochemical aspects of the reaction, characterizing the detected but up to now unidentified predominant products. The reactions are found to proceed in a highly asynchronous, nearly stepwise way, under implicit solvent conditions, with transition states that display significant aromatic features. We show Alder-Ene and direct hydride transfer pathways as two extremes of a continuous mechanistic spectrum for this kind of reactions, with the analyzed systems located approximately equidistant from both ends.
Active learning guided drug design lead optimization based on relative binding free energy modeling
Authors: Gusev Filipp , Gutkin Evgeny , Kurnikova Maria G. , Isayev Olexandr
Published: July 2022

In silico identification of potent protein inhibitors commonly requires prediction of a ligand binding free energy (BFE). Thermodynamics integration (TI) based on molecular dynamics (MD) simulations is a BFE calculation method capable of predicting accurate BFE, but it is computationally expensive and time-consuming. In this work, we developed an efficient automated workflow for identifying compounds with the lowest BFE among thousands of congeneric ligands which requires only hundreds of TI calculations. Automated Machine Learning (AutoML) orchestrated by Active Learning (AL) in AL-AutoML workflow allows unbiased and efficient search for a small set of best performing molecules. We applied this workflow to select inhibitors of the SARS-CoV-2 papain-like protease. Our work resulted in predicting 133 compounds with improved binding affinity among which 16 compounds with better than 100-fold binding affinity improvement. The hit rate obtained here is better than that of traditional projects where molecule selection is guided by an expert medicinal chemist. We demonstrated that a combination of an AL protocol provides at least 20x the common brute force approaches.
An Approach to High Throughput Measurement of Accurate Retention Data in Liquid Chromatography
Authors: Stoll Dwight , Kainz Gudrun , Dahlseid Tina , Kempen Trevor , Brau Tyler , Pirok Bob
Published: July 2022

Efforts to model and simulate various aspects of liquid chromatography (LC) separations (e.g., retention, selectivity, peak capacity, injection breakthrough) depend on experimental retention measurements to use as the basis for the models and simulations. Often these modeling and simulation efforts are limited by datasets that are too small because of the cost (time and money) associated with making the measurements. Other groups have demonstrated improvements in throughput of LC separations by focusing on “overhead” associated with the instrument itself – for example, between-analysis software processing time, and autosampler motions. In this paper we explore the possibility of using columns with small volumes (i.e., 5 mm x 2.1 mm i.d.) compared to conventional columns (e.g., 100 mm x 2.1 mm i.d.) that are typically used for retention measurements. We find that isocratic retention factors calculated for columns with these dimensions are different by about 20%; we attribute this difference – which we interpret as an error in measurements based on data from the 5 mm column – to extra-column volume associated with inlet and outlet frits. Since retention factor is a thermodynamic property of the mobile/stationary phase system under study, it should be independent of the dimensions of the column that is used for the measurement. We propose using ratios of retention factors (i.e., selectivities) to translate retention measurements between columns of different dimensions, so that measurements made using small columns can be used to make predictions for separations that involve conventional columns. We find that this approach reduces the difference in retention factors (5 mm compared to 100 mm columns) from an average of 18% to an average absolute difference of 1.7% (all errors less than 8%). This approach will significantly increase the rate at which high quality retention data can be collected to thousands of measurements per instrument per day, which in turn will likely have a profound impact on the quality of models and simulations that can be developed for many aspects of LC separations.

The article describes a rare case of endometritis after abdominal delivery. Attention is drawn to the possibility of developing ischemia and necrosis of the uterine tissue when using the Reverden suture, as well as the development of a significant local inflammatory response due to the individual reaction to the suture material used. A case of non-surgical integrated approach to the treatment of endometritis with local tissue rejection is presented. A positive outcome of organ-preserving therapy of endometritis in terms of ischemic and necrotic changes in the area of the postoperative suture on the uterus was shown. Conservative therapy included the use of a beta-lactam class carbapenem and an antimicrobial peptide complex.
DESCARTES AND SPINOZA ON THE PERFECTION OF GOD: A CONTRAST
Authors: ASTORE Rocco A.
Published: July 2022

After repeatedly reading Descartes’s Meditations on First Philosophy, what stills stands out most to this present essayist is Descartes’s notion of God’s perfection and how the perfection of the Divine includes the existence of the Almighty. Similarly, if we look to Spinoza’s Ethics Book I and the beginnings of Book II, we find comparable claims; namely, that the Almighty’s essence necessarily involves existence, and that this is a perfection of God alone. First, this article will detail how Descartes establishes God’s existence via the argument from perfection, and how this perfection of God reinforces the existence of such a supreme entity. Next, this piece will treat Spinoza’s understanding of God as that which must exist, and how this mandatory existence is solely of the perfection of God. Lastly, this paper will show that although Spinoza’s understanding of God’s perfection in his Ethics Book I and II may appear akin to Descartes, it would be incorrect to fully understand either philosopher’s views on God’s perfection as being entirely the same.

This paper presents the effective utilization of industrial waste steel mill scale in concrete. Tests were performed on concrete specimens incorporating 10%, 20%, 30%, and 40% steel mill scale by weight of sand and a control specimen. Results were assessed in terms of workability, compressive strength, flexural strength, and durability. The compressive and flexural strength of concrete incorporating a 20% steel mill scale was recorded higher as opposed to control and other percent replacement specimens. It was also observed that the durability and resistance against sulphate attack of concrete enhanced as the replacement proportion of mill scale were increased. Furthermore, the higher specific gravity of mill scale waste makes it a suitable material for heavyweight concrete members and radiation shield structures.

The article considers the role of the English language in global tertiary education (ESP/EAP, Adjunct ESP, EMI and ICLHE) and use a critical approach to analyze the current state of EMI integration into the educational process and tensions that arise due to conceptual gap in its adaptation to existing education policy. Applying a critical theory framework, the authors study the differences between EMI and internationalization that both instructors and university management adopt to curriculum design and pedagogy development. The research examines the ways internationalization and the EMI strategy affect curriculum design in universities; the ways university management incorporates global trends into curriculum design; the impediments that discourage the implementation of these programs identified by both educators and students. The researchers examine the EMI implementation under three dimensions: epistemology, teaching praxis, and ontological elements of students’ development and use document analysis related to the administration, curriculum, and course syllabi of EMI programs, followed by interviews with actors of the international classroom to outline the most challenging issues tertiary teachers, students, and university management face in EMI programs implementation. Moreover, the article examines evolving EMI perspectives as a means to boost internationalization and to improve teaching quality via integrating the best practices into the local context, including the expansion of teaching competence in both English language and pedagogy, introduction of language prerequisites for applicants, a constant adaptation of the curriculum to meet competence requirements.

There is a need to determine a wider range of factors to anticipate officer behavior in situations of complex interpersonal interaction together with guidelines for self-knowledge and self-development of professional competencies. This study examines the emotional intelligence of future naval officers during probation on ships as a predictor of their success in military service. The article shows that it is possible to predict the results of internships of cadets of a military university on ships through the partial elements and the overall characteristic of their emotional intelligence. One hundred cadets were examined using the N. Hall methodology “Diagnosis of emotional intelligence (Fetiskin, Kozlova and Manuylova variant), the “Progressive Matrices” test by J. Raven, and expert evaluations of the results of professional internships. The study evaluated the reliability of the distribution of indicators of the components of emotional intelligence “Emotional awareness”, “Managing your emotions”, “Self-motivation”, “Empathy” and “Recognizing the emotions of other people” and correlation analysis of the relationship of the integral level of emotional and non-verbal intelligence with the success of the training of future officers on ships. It concludes that psychological predictors of emotional intelligence and its partial elements predicts the results of professional activity due to self-regulation, self-control, and management of the emotional states of naval officers with fairly high reliability. The predictors identified contribute to the development of targeted corrective and preventive programs for the development of emotional intelligence among naval university cadets.

Published: July 2022

This is a study of how vocational education was transformed to deal with social distancing due to coronavirus infection in the Russian Federation. Data was taken from online delivery platforms such as Coursera, Timepad, and Edumarket. The demand for educational courses in Russia increased by 2.5 times in the first half of 2020 due to the spread of COVID-19. Despite this only 19% of learners are prepared to continue their learning after the quarantine measures are lifted. In the first half of 2020 programs on these platforms were focused on soft skills. There was an increase in programs for stress resistance, leadership, productivity, business, hobbies and art, parent-child relationships, and foreign language learning. The proportion of programs reliant on social communications decreased significantly. However, there was an increase courses in IT (blog / website development, machine learning), and medicine (ensuring safety in case of coronavirus infection, prevention of COVID-19, etc.). The study is of interest to the heads of regional educational departments, specialists of the continuing education in universities, professional educational organizations, non-governmental organizations of continuing education, labor exchange and those who are involved in continuing education and self-learning.

The article highlights the need for a new classification of scientific knowledge in order to reform the educational doctrine in modern Russian society. Several reasons explain this position. First, the constantly increasing volume of information leads to the “lag effect” of educational programs in comparison to scientific achievements; the effect of “redundancy” of knowledge cannot be envisioned and learned within the school year. Second, the post-non-classical stage of science is marked by the interdisciplinary nature of any knowledge and a focus on its object, which limits its representation within the framework of classical scientific differentiation and results in the loss of a holistic view of the world, which is unproductive in the context modern man’s cognitive styles. Third, modern education has evolved to a practice-oriented system that helps students adapt to world situations, but it has not altered considerably. The article examines prior classifications of sciences and puts forward a new conceptual model of systematization of knowledge that takes into account society’s educational demands. The anthropic principle underpins the proposed model of classification of sciences and knowledge systematization. This model can be used to create new educational programs based on the logic of integrative education, define constant academic disciplines for general and professional education, the order in which they should be studied, and the possibility of constant modernization of knowledge without expanding the number of academic disciplines. The provided methodology of scientific classification and knowledge systematization is thought to be useful in addressing the pressing issues in current education.
Characteristics of Social Sector Managers with Different Attitudes towards the Pandemic and Its Consequences
Authors:   Russian Presidential Academy of National Economy and Public Administration, Moscow, Russia, Sinyagin Yury
Published: July 2022

This article explores the attitude of managers towards the COVID-19 pandemic, providing an overview of their opinions on its consequences and potential impact on the country’s future socio-economic development. The study is important since it provides insight into how management styles may be effective in times of uncertainty and crisis. The research involved 661 managers, including 383 from the social sphere. The study utilized the management potential assessment questionnaire (PMO, version 5.0, Sinyagin, 2018), as well as a specially developed questionnaire. The participants were differentiated on two grounds: their attitude towards the pandemic either as a mobilizing challenge or as a serious not always surmountable difficulty in actual management. The findings reflect that the managers’ attitudes about the prospects for the country’s development after the end of the pandemic, commonly referred to as “optimism-pessimism”, have profound effect on their management strategies and performance indicators. It is revealed that readiness for learning and social mobility are key characteristics associated with optimistic future expectations. Internality, personality strength, a clear strategic life idea, and managerial experience are most associated with overcoming current circumstances. The paper concludes that developing and enhancing these qualities is a significant task that managers have in today’s uncertain world.

The importance of the problem under study stems from the rising demands of the state and modern society for a teacher’s professional growth. The objective of this paper is to establish a new format of pedagogical local history as a strategic resource for professional development of the teacher of the future. The notion of pedagogical local history has been explained from the standpoint of a branch of pedagogical science that investigates the past and current situation of education in the country and its areas. Through the generalization of sources, clarification and interpretation of formulations, a new approach was proposed to understanding pedagogy as it relates to the professional readiness of the future teacher to independently manage his or her career, to determine the trajectory of profession, and to set desirable goals to promote the cultural heritage through the interaction of times, the development of a new one, and the preservation of the past. By incorporating the main principles of digitalization into pedagogical practices, regional pedagogical traditions were articulated in the context of the cultural heritage of generations of the Orenburg region. Regional factors have been found as having a novel quality to the seemingly well-known processes of professional evolution of the future teacher due to their “territorial” nature. The influence of pedagogical local history on the construction of a distinctive individual-creative style of a new evolution teacher, as well as the enrichment of historical and pedagogical heritage, was assessed analytically. The authors conclude that evaluating the strategic resources of pedagogical local history, which could play a certain reinforcing role in preparing a teacher for innovative pedagogical activities, based on the traditions and historical experience of studying the region and understanding the modern problems of its development, is of current importance. The Google Forms tool was used to conduct an online survey of 235 instructors.
