The effective integration strategies of blended learning with traditional, designed a decade ago and proven effective, scalable, and flexible, now put forth several other challenges with delivery and evaluation. Especially for the elective courses, they demand assessments that add value to the course and the student's resume. The principles of elective design, the delivery tools, and techniques, the number of students, the significance of the course, etc., are some of the major evaluation parameters to be considered for the design of assessment strategies. This paper presents one such evaluation methodology, portfolio design, for the courses delivered in a blended learning model, which can also be adapted to the offline learning model. The model involved problem analysis, concept relation, design thinking, solution approaches, implementation, and presentation in the form of a portfolio. The portfolios were created online using various open source tools. The paper presents the model and design goals in detail. The first offering of the course had course projects, and the second offering had portfolio creation. The grades and attainment have improved in the second offering compared to the first one. There is also improvement in the course attainment where course learning objectives have remained the same. Portfolios are an effective strategy to evaluate one's course understanding. Portfolios can be an effective way to present the course realizations to the world. Keywords— assessment, blended-learning, elective design, portfolio

Abstract: This article describes the application of a systematic approach to an electric power technology engineering (EPTE) program that ensured highquality (Accreditation Board for Engineering and Technology - ABET) preparation. It describes how the Electrical Engineering Department at Palestine Polytechnic University (PPU), in Palestine, prepared for the EPTE program by defining and reviewing objectives and outcomes through a well-designed quality improvement process, and then implementing these evaluation results to develop the program. By obtaining results from courses delivered in two consecutive semesters, which could be more widened to a cycle of two consecutive academic years, it was possible to identify all student outcomes (SOs) with performances that either improved or deteriorated against a set threshold level of 80%. The final scores showed a mixed performance. While some SOs fell shortly below the set 80% threshold to an average level of 70%, others either met or exceeded threshold expectations. A deterioration in student outcome SO1 score related to ability of students to formulate and solve complex engineering problems. The SO2 score would require the laboratory and theoretical instructors to provide more discussion lectures and homework, in regard to circuit, system or process design, implementation and verification. The SO5 score showed that students needed to function more effectively as a team, while SO6 score indicated that students needed to improve their skills in experimentation, interpretation and analysis of data. The good scores; SO3, SO4 and SO7 related to ability of students to communicate effectively, recognize professional ethics and acquire and apply new knowledge.

Abstract: Many educations sector find it difficult to examine a student's performance on each assessment activities and provide feedback based on cognitive, reflective and psychomotor abilities. It is a difficult task for student tutors to individually assess each student's performance in each category (Remember, Understand, Apply, and Analyze) and provide feedback. As a result, a machine learning model is required to help tutors to evaluate the student performance and provide feedback to students and their parents. It serves as an extension of the student portal, allowing access to all information about students, including their assessment scores. A proposed model is to forecast individual student's and the entire class's strengths and weaknesses in single portal. This enables both teachers and students to adjust their teaching and learning methods as needed. This approach paved a way for tutors spent much more time with their slower learners, treated them with more compassion. Keywords: Machine learning, Cognitive skills, Tutoring, Student portal

Analysis of the reasons for the formation of defects in the 12-Cr18-Ni10-Ti steel billets and development of recommendations for its elimination
Authors:   Peter the Great St. Petersburg Polytechnic University, Russian Federation, Ryaboshuk Sergey , Kovalev Pavel ,   Peter the Great St. Petersburg Polytechnic University, Russian Federation
Published: March 2023

Introdution. Austenitic steel (e.g., AISI 304, AISI 321, AISI 316, AISI 403, 12-Cr18-Ni10-Ti, etc.) is widespread, which is caused by high corrosion resistance and the corresponding possibility of use in aggressive media. The following most common types of 12-Cr18-Ni10-Ti steel defects can be distinguished: integranular corrosion, martensitic orientation of the α-phase and ferrite δ-phase. The purpose of work: to analyze the defects formation reasons of the 12-Cr18-Ni10-Ti steel grade billets and to develop recommendations for their elimination. The methods of investigation. Tests of 12-Cr18-Ni10-Ti steel samples for resistance to integranular corrosion, metallographic analysis of defects were carried out in this work. Hardness measurements were carried out for various degrees of billets reduction. Thermodynamic calculations of phase equilibrium in multicomponent steel for different temperatures were performed by the Thermo-Calc software. Results and Discussion. It is determined that in order to prevent integranular corrosion, it is necessary to reduce the nitrogen and carbon content in steel at the stage of ladle refining to 0.05%, and also to ensure the concentration of titanium in steel is not less than the permissible value — 0.3%. These measures contribute to the reduction of Cr23C6 chromium carbides responsible for integranular corrosion. It is necessary to reduce the degree of compression of the billets to a level of no more than 50% to prevent the appearance of a ferromagnetic martensitic α-phase, since the formation of this defect is associated with a high degree of compression during drawing. The high-temperature phase of δ-ferrite exists in the metal structure in a wide temperature range. Reducing this range to 100 degrees or less by optimizing the composition of the carbon and chromium alloy in accordance with GOST 5632-2014 leads to a significant reduction of the amount of ferrite. However, it is not possible to completely eliminate it from the structure of steel. For all cases, it is necessary to assign austenization of billets in the temperature range of 1,050…1,100 °C.

Development and verification of the spending rule for the National Fund of Kazakhstan
Authors: Nurseiit Nurlan
Published: March 2023

Purpose- The article examines the key factors affecting the use of the National Fund of Kazakhstan (NFK) in 2005-2017, as well as the development of more effective methods and actions to improve its performance in the future.
Methodology- The study has developed a functional model of transfers from it to the state budget (spending rule), which helps to explain the observed dynamics of its use. The model was examined by using dynamic panel estimation techniques. As result it was found that transfers from oil fund to the state budget are dependent on economic activity, non-oil budget deficit and inflation in the country. An econometric test confirmed the correctness of the assumptions about the factors used in the model.
Findings- A multivariate forecast was also made for NFK's assets for the period until the end of 2022. Upon the favorable scenario, the value of the assets of the oil fund will reach 57.5 billion US dollars at the end of 2022. If world oil prices fall from 68 to 50 US dollars per barrel and remain at this level, the oil fund’s assets will be exhausted in 6-7 years. If oil prices fall to 30 US dollars, then the fund's oil assets will last only 5 years.
Conclusion- The principles of the formation and use of the NFK should be revised in order to ensure the long-term preservation of the fund's assets for future generations as originally planned.

Authors: Al-Zamil Mustafa Kh. , Kulikova Natalia G. , Vasileva Ekaterina S.
Published: March 2023

Epilepsy affects people of all ages and is a common disease. This neurological syndrome is determined by two or more spontaneous, unprovoked seizures that occur at least a day apart. The urgency of the problem lies in the serious adverse effects of epilepsy on the social and psychological well-being of patients.
This literature review discusses the main positions of modern epileptology in relation to sports for patients with epilepsy. The most recent clinical and experimental studies proving the safety of sports for patients with epilepsy and the positive effect of sports on reducing the number of epileptic seizures and improving the quality of life are listed. The antieleptic mechanisms of sports were demonstrated as hippocampal activation, stress realization, antiepileptic properties of acidosis, increased concentration of adenosine in brain tissues, release of -endorphins and inhibition of the kindling effect. Also in this obor are sports that cannot be practiced with epilepsy.
The opinion of epileptologists in Russia about sports in epilepsy does not differ from the opinion of most epileptologists of the modern world, and therefore patients are allowed to visit gyms and swimming pools in the presence of an instructor.

Published: March 2023

Currently, shoulder arthroplasty is being actively introduced into surgical practice, indications for operations are expanding, and the number of patients operated with severe injuries and diseases of the proximal humerus and shoulder joint is growing. The decrease in the effectiveness of restoring the painless functioning of shoulder, household independence and quality of life of patients after surgery may be due not only to the severity of damage to the shoulders joint structures of the before surgery, shortcomings in surgical techniques and the development of postoperative complications, but, possibly, the imperfection of medical rehabilitation programs for these patients.
To date, the content of the rehabilitation protocol for the early postoperative period has not been sufficiently substantiated, the need for strict immobilization of the operated joint, as well as the long-term benefits and effectiveness of early rehabilitation remains unclear.
The article attempts to summarize the available data on the physical rehabilitation of patients after shoulder joint replacement with various types of endoprostheses in the early and late postoperative periods.

One of the most urgent and socially significant problems of modern medicine is the widespread occurrence of orthopedic pathology, among which the leading place is occupied by diseases of the spine, accompanied by a steady increase in pain vertebrogenic syndromes that affect the functioning of the child's body as a whole. The prevalence of this nosological form in children, according to various population studies, ranges from 0.42 to 37%. ScheuermannMau disease (Scheuermanns kyphosis) is the most common osteochondropathy in children and adolescents and ranges from 0.48.3% of the pediatric population.
To date, the etiology of osteochondropathy of the spine is still unclear.
Medical rehabilitation of children with osteochondropathy of the spine is aimed at preventing further progression of deformity, normalizing posture, the functions of the cardio-respiratory system and includes: rational motor mode and nutrition, conservative orthopedic measures (corsetting), kinesiotherapy, hydrocolonotherapy, massage, positional treatment, restorative and hardening procedures, physiotherapy (electrical muscle stimulation), sports (skiing, swimming).
An important place in the review is given to the description of the stages of medical rehabilitation of children and adolescents with dorsalgia on the background of spinal osteochondropathy who underwent surgical treatment.

Published: March 2023

The development of a system of staged medical care for the medical rehabilitation of children with spinal dysraphism is an important and urgent task of pediatrics.
Spinal dysraphism is accompanied by flaccid paresis or paralysis of the lower extremities, as well as a violation of the function of the pelvic organs. In most cases, various deformations of the feet are observed, congenital dislocations of the hip are often found.
Medical rehabilitation begins immediately after surgical treatment in intensive care units and specialized departments. At the first stage, one of the important tasks is the correction of pelvic disorders. For this purpose, electrical stimulation, drug electrophoresis, magnetotherapy are used depending on the type of neurogenic bladder dysfunction. Currently, the effectiveness of high-intensity pulsed magnetotherapy in children with areflex bladder has been proven. The second stage of medical rehabilitation should be carried out if available in rehabilitation departments, medical rehabilitation centers and aimed at correcting motor impairment. Along with instrumental physiotherapy, modern technologies of physiotherapy exercises are actively introduced, aimed at strengthening the muscles of the lower extremities, preventing muscle atrophy.
The third stage of medical rehabilitation is the longest, carried out on an outpatient basis and includes various health technologies, such as aeroionotherapy, halotherapy, balneotherapy, and mud therapy.
Timely implementation of rehabilitation measures with the inclusion of physical factors in the early postoperative period and the consistent expansion of physiotherapy and kinesitherapy technologies at all stages of medical rehabilitation significantly increases the effectiveness of rehabilitation of patients with spinal cord injuries and improves their quality of life.

BACKGROUND: The therapeutic arsenal for the treatment of hypertrophic scars and keloids has expanded significantly in recent years. Traditional methods of treatment, such as intraocular injection of corticosteroids, pressure therapy and cryotherapy, are increasingly supplemented with new methods. The level of evidence for treatment approaches has increased due to the development of systematic reviews and national and international recommendations.
AIM: To study the effectiveness of pneumokinetic micro-jet "needle-free" delivery of corticosteroid drug and fluorouracil in hypertrophic scars.
MATERIAL AND METHODS: We observed 23 patients (with hypertrophic scars. The average age was 31.34.3 years. The duration of the existence of hypertrophic scars in the average group was 7.82.3 months. Previously, patients did not receive therapy for the correction of scars. All patients were treated with intra-cicatricial administration of durant corticosteroid and fluorouracil. The technology of pneumokinetic micro-jet "needle-free" was used.
RESULTS: A high effect was achieved in all patients. Thus, the total Dermatological symptom scale index decreased with localization of the process on the face by 79.1% (p 0.01), with localization on the neck by 81.2% (p 0.01), with localization on the abdomen by 73.4% (p 0.01).
CONCLUSION: The technology of pneumokinetic micro-jet "needle-free" delivery of corticosteroid drug and fluorouracil subdermally can be considered as the method of choice in this category of patients.
Modeling finite-fault radiation from the ωnspectrum
Authors: Beresnev Igor A. , Atkinson Gail M.
Published: March 2023

The high-frequency seismic field near the epicenter of a large earthquake is modeled by subdividing the fault plane into subelements and summing their contributions at the observation point. Each element is treated as a point source with an ω2 spectral shape, where ω is the angular frequency. Ground-motion contributions from the subsources are calculated using a stochastic model. Attenuation is based on simple geometric spreading in a whole space, coupled with regional anelastic attenuation (Q operator).

The form of the ωn spectrum with natural n follows from point shear-dislocation theory with an appropriately chosen slip time function. The seismic moment and corner frequency are the two parameters defining the point-source spectrum and must be linked to the subfault size to make the method complete. Two coefficients, Δσ and K, provide this link. Assigning a moment to a subfault of specified size introduces the stress parameter, Δσ. The relationship between corner frequency (dislocation growth rate) and fault size is established through the coefficient K, which is inherently nonunique. These two parameters control the number of subsources and the amplitudes of high-frequency radiation, respectively. Derivation of the model from shear-dislocation theory reveals the unavoidable uncertainty in assigning ωn spectrum to faults with finite size. This uncertainty can only be reduced through empirical validation.

The method is verified by simulating data recorded on rock sites near epicenters of the M8.0 1985 Michoacan (Mexico), the M8.0 1985 Valparaíso (Chile), and the M5.8 1988 Saguenay (Québec) earthquakes. Each of these events is among the largest for which strong-motion records are available, in their respective tectonic environments. The simulations for the first two earthquakes are compared to the more detailed modeling of Somerville et al. (1991), which employs an empirical source function and represents the effects of crustal structure using the theoretical impulse response. Both methods predict the observations accurately on average. The precision of the methods is also approximately equal; the predicted acceleration amplitudes in our model are generally within 15% of observations. An unexpected result of this study is that a single value of a parameter K provides a good fit to the data at high frequencies for all three earthquakes, despite their different tectonic environments. This suggests a simplicity in the modeling of source processes that was unanticipated.
Crustal and uppermost mantle velocity structure of northern Eurasia along the profile Quartz

Published: March 2023

The velocity structure of the crust and uppermost mantle beneath the DSS profile Quartz in northwestern Russia is determined using a linearized seismic tomography scheme. The analysis is performed on the northern 2200 km of the profile spanning from the Kola Peninsula, the Timan-Pechora basin, and the Uralian fold belt to the west Siberian basin. Refracted and reflected phases recorded from 28 chemical and two nuclear shot points are analyzed.

The inversion technique allows determination of the P-wave velocity structure and estimation of the depth of the crust-mantle discontinuity. Resolution analysis shows that the upper crustal structure and sections of the lower crust and uppermost mantle are well resolved. The modeled velocity and crustal thickness anomalies are confirmed by the resulting structure of the resolution matrix. Poorer ray coverage in parts of the lower crust and most sections of the uppermost mantle limits their resolvable structures.

A thick (over 10 km), high-velocity block (Vp > 7.0 km/sec) in the lower crust of the Precambrian beneath the Kola Peninsula; crustal thinning and a wide range of compressional velocities in the sedimentary basin structures; and a significant crustal root beneath the Uralian fold belt (42 to 45 km Moho depth with high lower crustal velocities exceeding 7.0 km/sec) were identified in the tectonic structure of northwestern Eurasia.

Published: March 2023

Introduction. All educational institutions have to adjust the learning format, from face-to-face to online learning, due to the COVID-19 outbreak. The sudden shifting of the learning format raised several problems for the students and led to mental health issues.

Aim. This study aimed to examine the effect of mental health on students’ learning achievement during online learning in the COVID-19 outbreak.

Methodology and research methods. This study used partial least square structural equation modelling (PLS-SEM) to examine the research model on a random sample of 518 respondents.

Results. The online learning activities during the COVID-19 outbreak have developed mental health issues, such as anxiety and depression. Furthermore, the results indicated that mental health negatively predicted the students’ learning achievement.

Scientific novelty. This study reveals certain situations and conditions that could be affected to the student’s mental health and learning achievement.

Practical significance. This study can be useful to the government as policymakers and administrators of the university as current research provides a critical understanding of the online learning influence on mental health and learning achievements of students. The government and administrators of the university should consider the right policy for learning activities during the COVID-19 outbreak. The government and administrators of the university also should provide student services to minimise the mental health issues among college students during online learning activities.

Introduction. Assessing students’ progress and predicting their future careers is paramount for any educational institution. The issue is particularly important for a teacher training institution, given the staff shortage in Russian schools and vocational education and training colleges. The educational process plays an important role in a graduate’s choice of future path, and hence, the problem of assessing the quality of this process arises as well.

An option of solving this problem is to create a feedback system in the university, which allows evaluating the dynamics of students’ competency formation levels in the monitoring mode.

Aim. The current research aims to develop and implement a multifactor competency model of a graduate of a pedagogical university, which can act as the basis for creating a system to monitor the quality of the educational process. The model takes into account psychological and socio-demographic factors, as well as students’ decisions in the field of a professional career.

Methodology and research methods. The approbation of the proposed model was carried out on the data obtained as a result of the survey of students of Tomsk State Pedagogical University in 2021. The data were processed by conventional and multivariate statistical methods: factor and cluster analyses. The sample consisted of 189 students of all training courses of the Physics and Mathematics Faculty at Tomsk State Pedagogical University.

Results. The analysis of the data obtained by using methods of multivariate statistics allowed the authors to obtain a variety of relationships between the factors taken into account. In particular, a pattern between the values of psychological scales, the level of competency formation and orientation of students in their choice of future profession was found.

Scientific novelty. The block structure of the model makes it possible to analyse each block separately and together, selecting factors from different spaces, introducing new blocks or spaces of factors, oriented to the (possibly new) purpose of the study, without changing the others.

Practical significance. The reasonableness of the obtained results of the study, the availability of a variety of algorithms for data interpretation indicate the real possibility of using in practice the proposed structure of the model, including the way of organising data as a monitoring system.

This study was conducted to determine the response of Salvia tomentosa Mill. and Salvia officinalis L. to different salinity levels. The salvia plants were grown in 8 L pots filled with the continuously aerated nutrient solution under different salt levels 1 (control), 2, 3, 4, 5 and 6 dS m-1 in fully automated climate chambers. The fresh and dry weight of shoot and root, stem length, leaf area, SPAD, CO2 fixation, root length, root diameter, root volume, leaf Na+, K+, Ca++ Cl- content, and amount of essential oil were determined. The increasing salt level decreased significantly plant growth of both Salvia species. However, highly significant differences were found between two Salvia species in terms of shoot and root biomass. Generally, S. tomentosa showed better plant growth performance in plant growth compared to S. officinalis. The Na+ and Cl- content of the leaves significantly increased with increasing salt concentration and the increase was higher in S. tomentosa. The amount of K+ in the leaves decreased due to the increasing salt concentration, while the amount of Ca++ varied depending on the dose. The study showed that the essential oil contents of the sage leaves could be increased with the moderate salt application. The increase in essential oil due to salt stress was higher in S. officinalis. The results showed that Salvia species can be cultivated in low and medium saline soils, second class waters can be used for irrigation of sages and essential oil yield of sages can be increased by using salt stress.
