Published: December 2023

The sharia life insurance program has two ways of managing funds, namely involving a savings element and not involving a savings element. Programs that do not involve a savings element do not have a clear division of tabarru’ funds that must be paid participant so it is the company's job to calculate it . In calculating the percentage of tabarru' funds used method Cost of Insurance (COI) . The COI method is method for calculating tabarru’ funds with using several parameters, namely mortality tables , investment value , management fees and discount factors . In this research, we will discuss how to obtain tabarru' funds using the 2019 Indonesian mortality table and the 2019 Indonesian mortality table with the Gompertz mortality law, Makeham mortality law and De Moivre mortality law. with method Cost of Insurance . Based on the case illustration, the results show that the tabarru' funds that must be paid by participants are directly proportional to the participant's age, management fees and insurance money, but inversely proportional to the investment value. Tabarru' funds will be greater if using the De Moivre mortality table so this can be a consideration for the company while the Makeham mortality table can be a consideration for participants.
On the Conditions for the Introducing Distance Learning in Russian Universities
Authors: Borovskikh A. V. 
Published: December 2023

Modern computer and Internet technologies make it possible not only to transfer educational materials to digital media, but also to implement in a remote format various teaching methods, diagnostics, individualization of educational interests and trajectories, and much more. In addition, modern technologies in this area allow us to do what was simply impossible within the framework of the conventional education system. But the issue of a reasonable measure of the use of these technologies and the adequate setting and implementation of tasks in this direction requires special work. The article presents the results of this kind of work carried out on the basis of a program-project approach. Although the work was carried out within the framework of the assignment of the FEMU to classical universities for mathematical education, the specifics of universities and mathematical education were not significant. The assignment was to determine the readiness of the mathematical faculties of universities for the systematic use of distance learning through an expert survey of FEMU members. The relevance of the question of the timeliness of the introducing distance learning in a particular situation, on the one hand, and the problematic nature of this issue, due to the lack of proper systemic, logical grounds for its solution, prompted the author to apply his own method, which is conceptually different from the numerous surveys and “experiences” available in literature. The application of this method (“double inversion of position” or, in other words, “double negation”: intent – objections – withdrawal of objections), made it possible to formulate three principal lists. The first contains an explicitly formulated framework in which the introducing distance learning makes sense; the second and third represent the research and development program necessary for the implementation of distance learning. And already on the basis of the first list, related to the current situation, a survey of experts was conducted, which made it possible to formulate the main conclusions on the problem under discussion. The results obtained fix a logical necessity that does not depend on private opinions or specific features of the situation.
Do “Top” Universities the Best in Everything? How the Status and the Size of Russian Universities Correlate to Student Engagement
Authors: Maloshonok N. G. 
Published: December 2023

The characteristics of the university that issued the higher education diploma are an important signal for the employer, indicating the quality of the graduate’s training. However, it remains unknown to what extent top Russian universities really differ in the quality of the educational process from other universities, and do not simply use their ability to admit the most talented and motivated students. This paper attempts to answer this question using student engagement indicators, which are considered worldwide as a valid tool for assessing the quality of higher education. The article aims to examine the relationship between student engagement and two institutional characteristics of universities (a special status and the size of the university) by employing survey data on 16,143 students studying at 401 Russian universities. The results demonstrate that students studying at federal, national research and flagship universities have comparatively lower class engagement and social engagement compared to students from universities without special status. In addition, students at institutions with a size between 1,000 and 3,500 students were the most engaged in class activities and, at the same time, disengaged, while a size of less than 1,000 students was negatively associated with disengagement. The results obtained, on the one hand, require further research into the relationship between institutional characteristics and student engagement. On the other hand, they indicate the need to increase the weight of indicators of the quality of the educational process in universities in government excellence initiatives aimed at identifying leading universities and supporting them, as well as the importance of developing valid indicators of the quality of the educational process that can be used as a criterion in such government competitions.
The influence of pedagogical reflection on design educational and professional plans of future teachers.
Authors: Golovchin M. A. 
Published: December 2023

The article analyzes the level of formation of pedagogical reflection among graduates studying the pedagogical specialties, and also generalizes the nature of the influence of pedagogical reflection on the educational and professional plans of future teachers after receiving a diploma. In the study, the author considers pedagogical reflection as a prestart state of a specialist, embodied in meta-competence, which allows one to assess one’s professional knowledge and skills as sufficient or insufficient to work in the acquired specialty.As a part of the study, a vision of the nature and structure of the phenomenon of pedagogical reflection founded on a competency-based approach was formed. The algorithm was proposed for assessing the level of formation of pedagogical reflection among graduates based on the use of factor analysis. The algorithm was tested on data from a questionnaire survey conducted in 2023 by the Voluntary Research Center of the Russian Academy of Sciences (RAS) among graduates studying to become teachers in the Vologda region. As a result of testing, it was revealed that after receiving a diploma, graduates with critical reflection more often than others want to connect their lives with work at school and see the future of their children in the teaching profession. Graduates with moderate and weak reflection are less likely to design appropriate plans. In the course of further generalization, a procedural model of the influence of pedagogical reflection on the professional development of a university graduate was developed.The scientific novelty of the study lies in the new perspective of posing the question of pedagogical reflection as a factor in educational and professional choice; the author’s methodology for summarizing the level of formation of professional reflection within the framework of factor analysis; a conceptual model that describes the influence of reflection on the professional development of a graduate, focusing on “soft” mechanisms that can be used to solve personnel problems in the education system. The article proposes a set of approaches to solving the problems of training reflective teachers, which can be introduced into management practice.
Service Learning in Russia: Scoping Review
Authors: Nikolskiy V. S. 
Published: December 2023

Over the past few years, the Service Learning approach has been increasingly introduced into the practice of Russian higher education institutions. Thereby researchers begin to take an active interest in this topic, and number of publications on service learning in the Russian context is growing. We are witnessing the emergence of a new area of educational research in our country. Under these circumstances, it is necessary to evaluate the successes in scientific knowledge, identify the existing gaps, and develop a programme for further research on service learning in our country. This circumstance determined the author’s interest in this topic and the choice of methodology in favour of a systematic review of the subject field. As a result, the author was able to identify an array of relevant publications, reconstruct the subject field, and identify seven main themes that have been covered to varying degrees in the literature: 1) specificity of the approach; 2) civicism formation; 3) application of reflective practices; 4) use of an evidence-based approach; 5) conceptualization; 6) external partners; and 7) the role of the teacher. The content analysis of the materials made it possible to identify the main characteristics of the publication array, identify lacunas and propose a programme of further research.

Published: December 2023

Background: Physicians may soon be able to diagnose Alzheimer’s disease (AD) in its early stages using fluid biomarkers like amyloid. However, it is acknowledged that additional biomarkers need to be characterized which would facilitate earlier monitoring of AD pathogenesis. Objective: To determine if a potential novel inflammation biomarker for AD, symmetric dimethylarginine, has utility as a baseline serum biomarker for discriminating prodromal AD from cognitively unimpaired controls in comparison to cerebrospinal fluid amyloid-β42 (Aβ42). Methods: Data including demographics, magnetic resonance imaging and fluorodeoxyglucose-positron emission tomography scans, Mini-Mental State Examination and Functional Activities Questionnaire scores, and biomarker concentrations were obtained from the Alzheimer’s Disease Neuroimaging Initiative for a total of 146 prodromal AD participants and 108 cognitively unimpaired controls. Results: Aβ42 ( p = 0.65) and symmetric dimethylarginine ( p = 0.45) were unable to predict age-matched cognitively unimpaired controls and prodromal AD participants. Aβ42 was negatively associated with regional brain atrophy and hypometabolism as well as cognitive and functional decline in cognitively unimpaired control participants ( p < 0.05) that generally decreased in time. There were no significant associations between Aβ42 and symmetric dimethylarginine with imaging or neurocognitive biomarkers in prodromal AD patients. Conclusions: Correlations were smaller between Aβ42 and neuropathological biomarkers over time and were absent in prodromal AD participants, suggesting a plateau effect dependent on age and disease stage. Evidence supporting symmetric dimethylarginine as a novel biomarker for AD as a single measurement was not found.

Background: Virtual reality (VR) technology has become increasingly used for assessment and intervention in the neuroscience field. Objective: We aimed to investigate the effects of a VR Training System, named VRADA (VR Exercise App for Dementia and Alzheimer’s Patients), on the cognitive functioning of older people with mild cognitive impairment (MCI). Methods: In this intervention study, 122 older adults with MCI were randomly assigned to five groups (the VRADA group ( n = 28), a bike group ( n = 11), a physical exercise group ( n = 24), a mixed group (physical and cognitive exercise) ( n = 31), and a non-contact control group ( n = 28). The VRADA group underwent 32 physical and cognitive training sessions, performed 2 or 3 times weekly for 12 weeks in the VR environment. All participants had detailed neuropsychological assessments before and after intervention. Results: A series of linear regression models revealed that the VRADA group showed improvement or no deterioration in cognitive decline in global cognitive function (MMSE), verbal memory (Rey Auditory Verbal Learning Test and WAIS forward test), and executive functions, mental flexibility (Trail Making Test B). Conclusions: This interventionstudy indicates that the VRADA system improves the cognitive function of elders with MCI.

Published: December 2023

Background: Alzheimer’s disease (AD) is characterized by amyloid-β (Aβ) plaque accumulation and neurofibrillary tangles in the brain. Emerging evidence has suggested potential interactions between the brain and periphery, particularly the liver, in regulating Aβ homeostasis. Objective: This study aimed to investigate the association of serum liver enzymes with brain amyloidopathy and cognitive performance in patients with complaints of cognitive decline. Methods: A total of 1,036 patients (mean age 74 years, 66.2% female) with subjective cognitive decline, mild cognitive impairment, AD dementia, and other neurodegenerative diseases were included using the Smart Clinical Data Warehouse. Amyloid positron emission tomography (PET) imaging, comprehensive neuropsychological evaluations, and measurements of liver enzymes, including aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase, total bilirubin, and albumin, were assessed. After propensity score matching, logistic and linear regression analyses were used to investigate the associations between liver enzymes, amyloid status, and cognitive performance. Additionally, a machine learning approach was used to assess the classification performance of liver enzymes in predicting amyloid PET positivity. Results: Lower ALT levels and higher AST-to-ALT ratios were significantly associated with amyloid PET positivity and AD diagnosis. The AST-to-ALT ratio was also significantly associated with poor memory function. Machine learning analysis revealed that the classification performance of amyloid status (AUC = 0.642) for age, sex, and apolipoprotein E ɛ4 carrier status significantly improved by 6.2% by integrating the AST-to-ALT ratio. Conclusions: These findings highlight the potential association of liver function on AD and its potential as a diagnostic and therapeutic implications.

Published: December 2023

Background: Measuring dementia knowledge can be a valuable tool for assessing the effectiveness of dementia awareness activities, identifying the potential benefits of dementia training programs, and breaking down common myths and stereotypes about dementia. Objective: To compare the psychometric properties of three widely used dementia knowledge tools, the Dementia Knowledge Assessment Tool 2 (DKAT2-G), the Dementia Knowledge Assessment Scale (DKAS-G), and the Knowledge in Dementia Scale (KIDE-G) in the Greek adult population. Methods: A convenience sample of 252 participants from the general population completed the survey online. Statistical analyses included Cronbach’s internal reliability, retest reliability, factor analysis, concurrent and construct validity, and floor and ceiling effects. Results: The DKAS-G had the most appropriate reliability levels (Cronbach’s alpha  =  0.845; retest reliability  =  0.921), whereas the DKAT2-G had satisfactory indexes (Cronbach’s α= 0.760; retest reliability  =  0.630). The KIDE-G showed unsatisfactory reliability (Cronbach’s α= 0.419; retest reliability  =  0.619). Construct validity was confirmed for all questionnaires, showing that all of them detected participants with pre-existing knowledge of dementia. Confirmatory factor analysis revealed a four-factor model for the DKAS-G and proposed the removal of 5 items. Floor and ceiling effects were found for the DKAT2-G and the KIDE-G, mainly among those who had previously participated in dementia training. Conclusions: The DKAS-G was found to have the highest levels of reliability and validity. The results prove that the DKAS-G meets the requirements for measuring dementia knowledge and evaluating dementia training programs in health professionals, caregivers, and the general population.

Published: December 2023

BACKGROUND: Many formulations and dosing regimens are available for hyaluronic acid (HA). OBJECTIVE: To compare different doses of linear, high-molecular weight (HMW) HA injections among patients with knee osteoarthritis (OA). METHODS: Hundred patients were included in this randomized, single-blinded trial and randomly divided into three HA injection groups. The first group received five weekly 20 mg HA injections, the second group received three weekly 32 mg HA injections, and the third group received a single 48 mg HA injection. Patients were evaluated at baseline, 1, 3, and 6 months after the last injection for pain, stiffness, and function using the visual analog scale (VAS) and the Western Ontario and McMaster Universities Arthritis Index (WOMAC) questionnaire. Quality of life, patient’s global assessment, and Timed Up and Go (TUG) test scores were also evaluated. RESULTS: There was significant improvement in the WOMAC, VAS-pain, quality of life, patient’s global assessment, and TUG test mean scores at all follow-up time points (p< 0.001). However, the groups showed no significant differences in WOMAC, VAS-activity pain, and patient global scores at any follow-up point. CONCLUSION: Intra-articular injections of different doses of linear HMW HA can improve pain, stiffness, function, and quality of life in patients suffering from knee OA over a six-month period.
