Authors: Ming Yue , Deng Zhihui , Tian Xianhua , Jia Yuerong , Ning Meng , Cheng Shuhua
Published: October 2022

Objective Hippocampal neuron apoptosis contributes to autism, while METTL3 has been documented to possess great potentials in neuron apoptosis. Our study probed into the role of METTL3 in neuron apoptosis in autism and to determine the underlying mechanism.Methods Bioinformatics analysis was used to analyze expressed genes in autism samples. Institute of Cancer Research mice were treated with valproic acid to develop autism models. The function of METTL3 in autism-like symptoms in mice was analyzed with behavioral tests and histological examination of their hippocampal tissues. Primary mouse hippocampal neurons were extracted for in vitro studies. Downstream factors of METTL3 were explored and validated.Results METTL3, MALAT1, and Wnt/β-catenin signaling were downregulated, while SFRP2 was upregulated in the hippocampal tissues of a mouse model of autism. METTL3 stabilized MALAT1 expression by promoting m6A modification of MALAT1. MALAT1 promoted SFRP2 methylation and led to reduced SFRP2 expression by recruiting DNMT1, DNMT3A, and DNMT3B to the promoter region of SFRP2. Furthermore, SFRP2 facilitated activation of the Wnt/β-catenin signaling. By this mechanism, METTL3 suppressed autism-like symptoms and hippocampal neuron apoptosis.Conclusion This research suggests that METTL3 can reduce autism-like symptoms and hippocampal neuron apoptosis by regulating the MALAT1/SFRP2/Wnt/β-catenin axis.

Authors: Jeong Ji-Hyeon , Bae Sung-Man
Published: October 2022

Objective There is limited understanding of which specific factors relate to smartphone addiction in the elderly. The aim of this study was to examine the relationship between types of smartphone use, digital literacy, and smartphone addiction in the elderly.Methods It used data from a survey on smartphone overdependence by the South Korea National Information Society Agency in 2019. Participants were 3,121 older people (1,627 males, 1,494 females; mean age=63.83 [standard deviation=2.88 years]). We conducted hierarchical multiple regression analysis.Results The results of a hierarchical multiple regression analysis indicated that smartphone usage time was positively related to smartphone addiction. Entertainment-seeking and life service types of smartphone use, and digital literacy were positively associated with smartphone addiction. Conversely, smartphone use for information-seeking and communication-seeking was negatively related to smartphone addiction.Conclusion This study suggests that it is necessary to understand different types of smartphone uses in the elderly and to educate the elderly on digital literacy to prevent smartphone addiction. In future studies, it will be necessary to re-confirm the relationship between smartphone usage type, digital literacy, and smartphone addiction in the elderly (including participants in their 70s or older).

Published: October 2022

Objective Although both partners of a married couple can have mental disorders, the concordant and cross-concordant categories of disorders in couples remain unclear. Using national psychiatric population-based data only from patients with mental disorders, we examined married couples with mental disorders to examine spousal concordance and cross-disorder concordance across the full spectrum of mental disorders.Methods Data from the 1997 to 2012 Taiwan Psychiatric Inpatient Medical Claims data set were used and a total of 662 married couples were obtained. Concordance of mental disorders was determined if both spouses were diagnosed with mental disorder of an identical category in the International Classification of Diseases, Ninth Revision, Clinical Modification; otherwise, cross-concordance was reported.Results According to Cohen’s kappa coefficient, the most concordant mental disorder in couples was substance use disorder, followed by bipolar disorder. Depressive and anxiety disorders were the most common cross-concordant mental disorders, followed by bipolar disorder. The prevalence of the spousal concordance of mental disorders differed by monthly income and the couple’s age disparity.Conclusion Evidence of spousal concordance and cross-concordance for mental disorders may highlight the necessity of understanding the social context of marriage in the etiology of mental illness. Identifying the risk factors from a common environment attributable to mental disorders may enhance public health strategies to prevent and improve chronic mental illness of married couples.

Published: October 2022

Objective Despite the well-documented relationship between emotion dysregulation and both post-traumatic stress disorder (PTSD) and alcohol use disorder symptoms, no studies investigated this issue in the context of the outbreak. Moreover, additional research investigating the role of mediators intervening in these pathways is required. Dissociation and emotional beliefs are two factors that may explain such relationships. However, a poor number of studies empirically tested their role. Methods A cross-sectional study on a sample of 719 community participants (32.5% males; Mage=34.36, standard deviation=14.38 years) was conducted. Participants fulfilled a battery of self-report questionnaires measuring levels of PTSD outbreak-related symptoms, alcohol use disorder, emotion dysregulation, emotional beliefs, and dissociation. Results Partial r-Pearson correlations showed that PTSD symptoms’ level was positively and significantly related to all variables investigated in the study whereas alcohol use disorder level was positively and significantly associated with emotion dysregulation and only some dimension of emotional beliefs and dissociation. Results drawn from a structural equation model highlight the mediating role of both emotional belief and dissociation in the relationship linking emotion dysregulation and alcohol use disorder whereas only dissociation, but not emotional beliefs, mediated the link between emotion dysregulation and PTSD symptoms. Conclusion Most of the hypotheses have been supported stressing the relevance of both dissociation and emotional beliefs in PTSD and alcohol use disorder symptoms. These two variables appear important framework from which deepen the impact of emotion dysregulation in psychopathology.

Published: October 2022

Objective Owing to prolonged social distancing and the resultant isolation, the prevalence of depression and suicidality has increased during the COVID-19 pandemic. This study aimed to investigate the severity of depression and suicidality in Korean community populations and examine their awareness of suicide and suicide prevention during the pandemic.Methods This study surveyed a community population in 2020 and 2021, involving 668 participants. We evaluated the severity of depression and suicidality using the Patient Health Questionnaire-9 and Beck Scale for Suicidal Ideation as well as questions about awareness of suicide. We performed a correlation analysis to confirm the association between variables, and compared participants’ suicide awareness according to the severity of depression.Results The severity of depression and suicidality in the community population decreased in 2021 compared to 2020. Awareness of the importance of suicide prevention increased in 2021, but the percentage reporting that it is possible decreased slightly. The group with higher depressive symptoms reported a lower possibility of suicide prevention.Conclusion Increasing social interest in suicide, as well as awareness of suicide prevention, is important for reducing suicide rates. Suicide prevention campaigns, education, and social policies are needed, particularly during the pandemic.

Published: October 2022

Objective We compared retrospectively the seizure variables of electroconvulsive therapy (ECT) patients after administration of rocuronium-sugammadex or succinylcholine as a muscle relaxant with propofol anesthesia.Methods The sample comprised 134 ECT patients. The mean age was 33.6±10.48 years. Anesthesia induction was provided with propofol one mg kg-intravenously (IV) followed by succinylcholine 0.5 mg kg-1 IV (n=68) (Group S) or rocuronium 0.3 mg kg-1 IV (n=66) (Group R). For patients who were given rocuronium, reversal of the residual neuromuscular block was accomplished with sugammadex (1.5 mg kg-1 IV). First session seizure variables were compared between the two groups. We also presented the clinical outcome with Clinical Global Impression-Improvement (CGI-I) and overall adverse effects.Results EEG seizure durations in Group R (55.09±36.11 s) and Group S (47.00±26.33 s) were comparable and were not significantly different (p=0.432). The clinical efficacy of ECT measured by CGI-I in both groups was comparable (p=0.075). There were no major complications or death during or after ECT.Conclusion The results of this study show that the use of rocuronium-sugammadex as a neuromuscular blocker instead of succinylcholine during ECT with propofol anesthesia produces similar results in terms of seizure variables and clinical outcomes.

Published: October 2022

Objective To investigate the predictors of remission by 4 treatment steps in depressive outpatients receiving 12-week psychopharmacotherapy.Methods Patients were consecutively recruited at a university hospital in South Korea from March 2012 to April 2017. At baseline, 1,262 patients were evaluated for sociodemographic and clinical data including assessments scales, and were received antidepressant monotherapy. For patients with an insufficient response or uncomfortable side effects, next treatment steps (1, 2, 3, and 4) with alternative strategies (switching, augmentation, combination, and mixtures of these approaches) were administered considering measurements and patient preference at every 3 weeks in the acute treatment phase (3, 6, 9, and 12 weeks). Remission was defined as a Hamilton Depression Rating Scale score of ≤7.Results In the multi-variate logistic regression analyses, remission was predicted by higher functional levels in patients received Step 1 and 2 treatment; by lower life stressors in Step 1; by higher social support in Step 3 and 4; and by lower suicidality in Step 1–3.Conclusion Differential associations were found between symptoms or functions and treatment steps, which suggested that multi-faceted evaluations at baseline could predict remission by treatment steps.

Published: October 2022

Objective We explored whether a history of sleep disorder affected a current diagnosis of cognitive impairment and clinical conversion in a non-demented elderly population.Methods Comprehensive clinical data collected as part of the Alzheimer’s Disease Neuroimaging Initiative (ADNI) was analyzed. A history of sleep disorder was recorded in the recent ADNI medical database. Standard clinical and neuropsychological tests were performed both at baseline and follow-up visit. Multiple logistic regression analysis was performed after adjusting for age, sex, education, apolipoprotein E ε4 status, vascular risk score, body mass index, Geriatric Depression Scale score, and use of sleeping pills.Results A total of 391 cognitively normal individuals, 303 with early mild cognitive impairment (MCI) and 364 with late MCI were included. Sleep disorder history was significantly associated with an increased risk of MCI but not with clinical conversion. A history of insomnia or obstructive sleep apnea (OSA) significantly increased the risk of MCI, but only an OSA history predicted progression to Alzheimer’s disease (AD) dementia.Conclusion Our findings suggest that a sleep disorder history usefully aids early detection of cognitive impairment and emphasize that such sleep disorder, particularly OSA, is important as potential target for AD prevention.

Published: October 2022

Objective This study aimed to explore the relationship between childhood physical abuse and suicidal ideation considering the effects of genetic and environmental factors in patients with post-traumatic stress disorder (PTSD) by focusing on brain-derived neurotrophic factor (BDNF) polymorphism and social support, respectively.Methods One-hundred fourteen patients with PTSD and 94 healthy controls (HCs) were genotyped with respect to BDNF Val66Met polymorphism. All participants underwent psychological assessments. The hierarchical regression analysis and the simple slope analysis were conducted.Results As for patients with PTSD, the moderation effect of BDNF polymorphism was significant but not for social support. Specifically, the BDNF Val/Val genotype worked as a risk factor and strengthens the relationship between childhood physical abuse and suicidal ideation. As for the HCs, the significant moderation effect was found only in social support, but not for BDNF polymorphism. The relationship between childhood physical abuse and suicidal ideation was weakened for the HCs with high social support.Conclusion This study demonstrated a significant BDNF genetic vulnerability for suicide in patients with PTSD who experienced childhood physical abuse. Our results suggested that social support provided a mitigating effect on the relationship between childhood physical abuse and suicidal ideation only in the HCs.

Islamic Perspective on Organ Donation and Brain Death
Authors: Khan Ahmad , Tidman Melanie M.
Published: October 2022

Worldwide and in the countries, Islamic scholars do not have a consensus on the criteria and definition of brain death. This lack of consensus on the definition of brain death and its legal status has resulted in delays in withdrawal of care and futile care to the brain-dead patient population that negatively strains the limited resources for human organs in the Islamic community. Also, Islamic countries with organ transplantation resources lack legislation on endorsing brain death and its legal status as death which creates delays in harvesting viable organs from eligible donors. These delays can negatively impact the life quality of patients with end-organ failure waiting for an organ and make organs non-viable for transplantation, adding to the already existing shortages in Islamic countries. This brief review aims to clarify some of the barriers in the determination of brain death and organ donation in Islamic countries and address religious and ethical issues that exist that affect issues of access.

Published: October 2022

An automation system was designed to measure and monitor the amount of liquid fertilizer sprayed on a direct drill machine with the ability to apply liquid fertilizer. The clogging of spray nozzles is a common problem in liquid fertilizer machines. The objective is to detect clogged spray nozzles during the application of liquid fertilizer and to allow the tractor driver to monitor the amount of liquid fertilizer discharged with this designed automation system. It gives a visual warning to the driver when the flow is zero. Flow sensors are mounted on the spray nozzles of the machine. The machine was operated at 540 rpm PTO speed. A total of 30 measurements were taken from each flow sensor with 3 replications. The actual volume was found from the amount of liquid collected in the scaled vessels that are placed under the spraying nozzles and the measured volume obtained from the flow sensors. The calibration curve of the liquid fertilizer system was created by performing a regression analysis with measurements taken from the sensors and scaled vessels. At the same time, the real volume and the volume measured by the sensor were compared with the t-test and analyzed whether there was a statistically p< 0.05 difference between the measurements. As a result of the measurements, the volume measured by the sensor was slightly higher than the actual volume. The mean difference was calculated as 0.17 liters and the standard deviation as 0.08 liters. The regression curve between the actual and the measured volume shows that there is a high linear relationship and the regression coefficient was calculated as R2= 0.947. At the same time, since p=0.012 (p<0.05) was found as a result of the independent two-way t-test, it was determined that there was no statistical difference between the actual volume and the measured volume.

Authors:   Moscow Aviation Institute (National Research University), Vikulin M.A.
Published: October 2022

In modern society, a gap has formed between education and production. University graduates do not always have the opportunity to find a job in their specialty, and employers do not know about the achievements of their graduate candidates. One way to solve this problem is to publish personal achievements by students in an electronic portfolio. With the help of an electronic portfolio, a student will not only be able to keep an up-to-date list of all his achievements and publications, but also share this list with potential employers. In addition, storing information about all the achievements of university students will optimize the process of applying for an increased scholarship. In this paper, the author describes the developed services for posting student achievements and checking them in the e-learning system.

The article discusses peculiarities of teaching a professional foreign language to masters of engineering profile and draws the need to use authentic texts in the process of preparing students for scientific research. Building skills of analytical work with authentic texts is considered to be one of the principal means of masters’ professional training, and the problem of text selection and competent organization of working with it is becoming a key target when teaching to read. The main selection criterion is a professionally relevant authentic text containing new and important information for master students as such texts stimulate learners’ language activity. The information provided may become the material to analyze in the theoretical part of master thesis, to write a scientific article, to prepare conference presentation, etc. Working with authentic texts requires hard work but contributes to the development of skills to find and critically process information, consider the foreign engineering experience, independently set and solve scientific problems, develop scientific methods (comparative, analytical, phenomenological, etc.). Competent organization of classroom and individual work of master students with authentic texts is the basis for effective learning.

The proposed article presents the problem of applying an interdisciplinary approach to the study of the phenomenon of giftedness of teachers and students. Global global changes in various spheres of human activity determined the need for innovative changes in the training of students. The need for the development of students ‘ intellectual abilities as moderators of world progress has sharply increased. The manifestation of the subjectivity of students contributes to the effectiveness of implementation in the surrounding society. The methodological orientation of the organization of the modern educational process at the university can be the ideas of personal development in modern society, the definition of the means of developing students ‘ personal functions, the definition of cognitive and personal components of the educational process. Prerequisites are being created for the creation of a new paradigm of education, which assumes the maximum development of students ‘ creative abilities, various types of their giftedness. It is supposed to change the content and technological component of the educational process associated with the digitalization of modern education. In the current conditions, the very concept of educational activity is gaining a new interpretation, in which individual forms of organizing the learning process are becoming increasingly important. Thus, the transformation of the pedagogy of literacy into the pedagogy of development, disclosure of creative abilities and giftedness of students can be realized. The importance of an intellectual resource in the competition between countries has made the problem of identifying and developing the talent of teachers and students one of the national projects in our country. The multidimensional nature of the phenomenon of giftedness has led to its study on the basis of an interdisciplinary approach from the positions of different sciences. The analysis of the genesis of this problem is contained in the works of various representatives of historical, psychological and pedagogical sciences. The emergence and development of creative abilities among individual representatives of society in ancient times appeared due to the improvement of tools and the separation of physical and mental labor. There was an opportunity to develop various abilities in individual representatives of society, to identify the giftedness of teachers.

Published: October 2022

The popularity of e-learning systems leads to their implementation in various areas of education, which requires extensive functionality from the systems themselves to work with students. One of the areas important for ensuring the quality of education is the need to be able to assess the activity of students online. At the same time, the assessment rules may vary for different courses, since the indicators of successful completion of the course are set by the author himself. Thus, to implement an assessment system, a flexible, but at the same time easy-to-use system is required that allows both setting up calculation formulas and viewing various reports on student progress. In this paper, the authors consider the features of using the functionality of the LMS MOODLE e-learning system for working with grades, and also share recommendations for using the tools available in the system.

The article is devoted to the development of approaches to the improvement and management of the system of physical education of students. It is established that the introduction of changes in the physical training of students requires the search for new criteria for the formation of individual components of the methodological system, its content and means. It is proved that the preservation of physical education as an academic discipline in universities should be considered not as an additional academic burden on the student, but as a means that positively affects the activation of mental activity, the restoration of intellectual and physical performance. A retrospective analysis of the development and formation of the system of physical education of students in the Russian Federation was carried out, which made it possible to identify the main directions of its development based on the identification of individual positive and negative factors that cause changes in the socio-economic and cultural development of the country. It is noted that the preservation of physical education at the university now depends on the competence of the university management, the authority of the heads of physical education departments and the search for new balanced solutions. It is found out that the system of physical training is a conditioned type of physical education system, which is based on ideological, program-normative, scientific methodological and organizational principles that provide physical education of students.

The article considers the relationship between construction risks and organizational and technological reliability of construction, their mutual influence on each other in order to increase the economic efficiency of construction production. The main purpose of the study is to identify the main elements of risk management in order to improve the organizational and technological reliability of construction. It is noted that the construction is characterized by a number of features that determine the types and degree of influence of risks. It is noted that external risks cannot be influenced by the enterprise, therefore they should be predicted and try to reduce their negative impact on construction. Examples of the main risks in the construction of facilities in the region, as well as the main methods of risk assessment are given. The scheme of functioning of the risk management system in a construction organization is proposed. A system analysis that determines the impact of risks on the performance indicators of construction production contributes to improving the organizational and technological reliability of a construction enterprise. When writing the article, the method of expert assessment, observation, analysis and synthesis was used.

The lack of clear requirements for the parameters of video surveillance systems provokes the presence of at least three significant problems discussed in this article. Their presence generates a significant contradiction between the image quality that is declared by the manufacturers of video surveillance systems, and the image quality that is expected by the end user. The lack of a standard for determining an acceptable image gives rise to the presence of various tuning tables that allow you to determine certain characteristics of the output signal. However, this does not mean that the consumer is guaranteed to receive a high-quality image that could be evaluated in terms of the effectiveness of the video surveillance system. Thus, the solution to the issue of assessing image quality lies in the standardization of the parameters specified by the equipment manufacturer.

The article discusses the basics of risk assessment of educational processes of the quality management system of additional professional education (QMS APE) of a higher educational institution. The approaches to assessing the risks of educational processes in the context of risk-oriented thinking in the management of the QMS of the university are analyzed. The modular-hierarchical structure of educational risks is determined, correlated with the totality of interrelated and interacting processes of the QMS of APE. The expediency of applying tools and technologies of statistical justi cation to the assessment of risks arising from the management of educational processes is substantiated. A procedure for assessing educational risks based on the rank method is proposed, which allows not only to identify threats arising as a result of process management, but also to form a generalized assessment of their impact on the functioning of the QMS as a whole. The adaptation of the proposed approach to risk assessment of QMS APE processes is considered on the example of the «Recruitment» subprocess. The expediency of using the proposed approach to risk assessment in relation to the QMS processes of a higher educational institution is argued.
