Adaptation of First-Year Students to Study at a Pedagogical University within the Framework of Educational Practice
Authors: Antonova N.A.
Published: September 2023

The article is devoted to the urgent problem of adaptation of first–year students - future physics teachers to university education. The relevance is confirmed by the fact that it is based on the law “On Education in the Russian Federation”, which, among other things, states the need to achieve a high quality of education without compromising the health of students. The concept of “adaptation of students”, factors and a set of problems of a first–year student are considered. The components of adaptation in the educational process in teaching physics are presented: psychological and social, health-preserving, ergonomic, content-procedural — on which we can work to a greater extent at the Department of Physics and Methods of Teaching Physics. The results of the survey and diagnostics made it possible to identify the difficulties experienced by future physics teachers in the first year of study, which makes it possible to create conditions for the adaptation of first-year students to the university format of educational and cognitive activity. Recommendations for organizing the process of adaptation of first–year students — future teachers of physics — to study at a university within the framework of educational practice are highlighted.
Scheme of Lev Vygotsky's Theory. Part 1
Authors: Sizikova T.E. , Kudryavtsev V.T.
Published: September 2023

The relevance of referring to Lev Vygotsky's works and discovering the unknowable in them is a natural phenomenon that accompanies brilliant works of science, literature, art, etc. Discoveries are accidental and non-accidental at the same time, so they are either accepted immediately or pass the "corridor" of criticism. The history of the formation of Vygotsky's psychology is also the history of our way of understanding Vygotsky. The aim of the article is to reveal what Lev Vygotsky himself might not have highlighted. We have tried to penetrate into the logic, the scheme of his thinking. It is possible to carry out the reconstruction in different ways, as evidenced by the experience of the world "vygotskopovedeniya". In this article we argue the hypothesis about the logic of triangulation by L.S. Vygotsky. Triangulation acts as a method of analyzing the psyche with the help of "units of analysis of the whole". In our opinion, L. S. Vygotsky analyzed the psyche as a triangular dynamic network. The network structure allows to reveal new, logically substantiated connections between its elements. He constructed a logical "construct" allowing to confirm it empirically. The basis of the network is formed by trinities of mental functions and connections between trinities, when the same function is included in different trinities. A trinity is formed and in it`s development represents a synthesis of the elements forming it. Each mental function is a whole and reflects in itself a larger whole, i.e., the psyche. It is in the structure of the trinity network that this is most clearly traced. The analysis undertaken by L.S. Vygotsky undoubtedly belongs to the post-nonclassical type of scientific rationality.
L.S. Vygotsky and the Digit: Challenge for Cultural-Historical Psychology
Authors: Smirnov S.A.
Published: September 2023

The article ponders, if it is at all possible to include digital technologies into the process of mediation. The latter being the core of cultural-historical psychology by L. Vygotsky. In order to facilitate the discussion, the author outlines the nature of the virtual world, made by digital technologies. It was postulated by a number of researchers that digital technology could serve both as a tool and as a sing. And so — it can be part of the mediation practices. This article claims that digital technologies create a unique environment (virtual reality) that dictates particular ways of conduct, especially for children and teenagers. The author demonstrates how digital technology creates splinter segments in the mediation process, which makes an adult to leave the communication with a child. Which leads to so-called digital chasm, and a child descends into the virtual reality without living through the mediation process. This is why we claim that digital technology can’t serve as a sign, the way Vygotsky describes them. The article lists parameters and consequences of the digital schism, such as: event shift, narrative intervention, inversion of functions and flattening of the horizon of meaning. The article proposes a solution — a construction of a search scenario in schools. This search scenario consists of several stages: challenge, analysis, ask-search, discussion, reflection and articulation of knowledge. Each of these stages can include digital technologies in various ways. The article concludes the algorithmic nature of modern schools makes a pupil’s behaviour “digital” before digital technologies themselves. And so, in order to overcome the digital schism, one needs to establish search scenarios as a teaching model before introducing digital technologies during a lesson.
Risks and intrigue of "digitalization”. Afterword to the articles by Gromyko and Smirnov
Authors: Elkonin B.D.
Published: September 2023

As part of the reflection on the articles of Yu.V. Gromyko and S.A. Smirnov, the risks and opportunities of the "digitalization" of learning are considered. Risks are related to the "absorption" of subjective forms of activity in computer programs. Opportunities are in the construction of programs that initiate not only following algorithms, but also their trial and error correction.
Clinical-Psychological and Socio-Demographic Factors of Suicidal Behavior and the Risk of its Chronicity: a Review of Studies
Authors: Subotich M.I.
Published: September 2023

Relevance. The article presents an overview of studies on clinical, psychological and socio–demographic factors of suicidal behavior and the risk of its chronicity. According to the WHO, 800,000 people die each year by suicide, and many others seek help from medical centers after a suicide attempt. Suicide and suicide attempts are a medical, social and psychological problem. Purpose of the study. Evaluation of the role of various factors in the chronification of suicidal behavior and an increase in its risk. Results. According to numerous studies, most often repeated suicide attempts are made by people with borderline personality disorder and other personality disorders, often in combination with depressive and anxiety symptoms. The motives for suicide in this group of patients may be emotional regulation, coping with dissociation, stress, and more often do not contain the desire to die. This group of patients tend to self-cut in the limbs or attempt self-poisoning. A distinctive feature of suicide attempts in individuals with schizophrenia, severe depression and bipolar disorder is the intention to die, combined with more severe methods of self-harm, in contrast to patients with personality disorders. The risk of chronification of suicidal behavior is higher in people of working age who have experience in the use of psychoactive substances, low social status and wealth, and the unemployed. This group of patients needs to be provided with medical, psycho-social assistance, since without treatment and psychological support, the risk of chronification of suicidal behavior, an increase in symptoms of depression and the completion of suicide increases. Conclusions. Chronic suicidal behavior requires active interdisciplinary team work with patients based on a biopsychosocial model already at the stage of the first hospital admission after a suicide attempt. It is important to take into account the specifics and characteristics of suicidal behavior, work styles may differ depending on the diagnoses, age and motives of suicidal behavior.
Investigation of the Psychometric Properties of the Hospital Anxiety and Depression Scale (HADS) Recommended for General Medical Practitioners, on a Sample of Patients with Impaired Motor Functions

Published: September 2023

The aim of the study is to investigate the psychometric characteristics of the Hospital Anxiety and Depression Scale (HADS) on a sample of patients with impaired motor functions. HADS was used to examine the current psychoemotional state of 73 women and 27 men aged 62.1±13.7 years who were in the hospital for inpatient rehabilitation for motor function disorders arising from a stroke (n=50) or developing against the background of chronic musculoskeletal disorders (n=50). Independent of the psychologist, a psychiatrist examined the same patients, filling out Hamilton Anxiety and Depression scales. A comparison of the findings led to the conclusion of overdiagnosis with the HADS subscales. At the same time, it is shown that the questionnaire items have satisfactory indices of discriminativeness and internal reliability. The combination of low content and convergent validity of some items of the questionnaire allowed modifying subscales, reducing the number of items without prejudice to psychometric characteristics. By comparing the data obtained with an objective external criterion for the Anxiety (HADS-A) and Depression (HADS-D) subscales, new cutoffs (9 points) were determined for diagnosing the presence or absence of anxiety and depression, which allows to use this version of the test more effectively for screening the current psychoemotional state in patients with impaired motor functions who enter the second stage of medical rehabilitation.
Phenomenology and Functions of Suicide Humor: A Theoretical Review
Authors: Govorov S.A. , Ivanova E.M.
Published: September 2023

The present article provides an analysis of suicide humor as a specific form of dark humor and its relation to suicide behavior. It is suggested that such humor and suicide taboo, as well as communicative taboo on the topic of suicide, are interrelated. The complexity and inconsistency of society’s attitude towards suicide and acts of self-sacrifice are analyzed. Presumably suicide humor represents a rather complex multidimensional phenomenon of communication, which functions as a tool for reflection on suicide taboo. It is suggested that suicide jokes can influence suicide behavior either by strengthening or weakening suicide motivation. Various mechanisms that may underlie the adaptive nature of such humor are considered through its relationship with the psychological factors of suicide risk. The article provides a hypothesis on how such humor can be used as a tool for suicide risk’s clinical diagnosis; it also discusses the reasons for suicide jokes’ popularity among adolescents.

Published: September 2023

Suggested is a new approach to development of the adaptive systems for psychological diagnostics, which can be considered as artificial intelligence tools for assessing the subject activities. It is based on the convolution of the applied Markovian process representing a diagnostic procedure under study into the quantum representation, which makes it possible to reveal the structure of this procedure with the aid of the quantum spectral analysis. When small samples of empirical data are in use to set up diagnostic tools, the considered quantum estimates have significant advantages over the relevant likelihood and Bayesian estimates as well as over the simpler estimates based on the neural networks.
The Role of Cognitive Distortions in Maintaining the Pattern of Sexual Violence
Authors: Demidova L.Y.
Published: September 2023

Distorted judgments supporting commitment of criminal sexual acts are widely used in persons with abnormal sexual behavior and considered by foreign researchers as one of the dynamic risk factors of relapse of sexual crimes against minors. The submitted article is an analytical review of the main foreign research papers on the problem of cognitive distortions in sexual offenders. Various attempts to conceptualize and categorize cognitive distortions are presented with their theoretical and empirical verification, structural characteristics and some features of the development of such distorted judgements. The self-report questionnaires are mainly used in foreign studies of cognitive distortions, also samples of sexual offenders are studied include both persons with sexual disorders and situational offenders. The article shows the necessity of distinguishing between prior and posterior cognitive distortions, as well as self-justification inherent in human nature and distorted judgements that contribute to the commission of criminal acts. It has been suggested that the assessment of cognitive distortions should be carried out not only by unified questionnaires, but using a phenomenological analysis of situational behavior and a retrospective analysis of criminal’s beliefs before the latter committed the incriminated act.
Professional Burnout of Medical Workers Before, During and After the Pandemic
Authors: Suroegina A.Y. , Kholmogorova A.B.
Published: September 2023

The problem of professional burnout attracted the attention of researchers and health care organizers even before the pandemic, it was expected that occupational risks during the pandemic would increase the severity of the indicators of professional burnout of physicians, and a decrease in the number of patients and the end of the pandemic would reduce the indicators. Studies have shown the presence of fluctuations in the severity of professional burnout during periods of various waves of morbidity. It is noted that during the pandemic, the most effective coping methods were coping related to obtaining family support and social approval. But after the end of the pandemic, there was a decrease in the effectiveness of these methods in the situation of combating professional burnout, and the search for the meaning of their work turned out to be more productive. It was noted that after the pandemic, compassion fatigue and the “second victim syndrome” played an important role in professional burnout. As a conceptualization of the data obtained on the professional burnout of medical workers before, during and after the pandemic, there was a model of psychological experience of a natural disaster. Studies have shown that certain groups of medical workers are more susceptible to professional burnout. Among them, a special place is occupied by students and residents who are at risk both before and during the pandemic and after it. Despite the increase in psychological stress, psychological exhaustion, the willingness of doctors to seek psychological help remains low at different stages of the pandemic and is associated with fear of discrimination in the professional environment.

Philosophy of Culture — Psychology — Linguistics Triad: Bronisław Malinowski’s Conception as regards Interdisciplinarity
Authors: Averyushkin A.N. , Kanel I.V.
Published: September 2023

A shift in philosophical thinking towards language, signs and their meanings marked an early 20th century. It was a contrast to the metaphysical and rationalist thought style of classical philosophy, centred on reason as expressed in Descartes’ «Cogito, ergo sum». Language, like culture, reveals the essence of what is happening; the word is the key to understanding the truth that can unite peoples and destroy civilizations. In 20th century, too, culture continued to be studied from various angles, including biological and psychological. Influenced by W. Wundt’s ideas on folk psychology (Völkerpsychologie), B. Malinowski considered it crucial to explore the local language and culture to discover the full meaning of words and expressions. He argued that the true meaning of a word could only be seen by contextualizing it with other words, and offered his own approach to translating. Malinowski’s term «situational context» became a key concept in functional linguistics.
Evaluation of Digital Educational Technologies by University Teachers
Authors: Sorokova M.G. , Odintsova M. , Radchikova N.P.
Published: September 2023

A comparative analysis of the assessments of digital educational technologies by teachers (mean age – 49±12 years) of various Russian Federation universities who have experience in using them in their professional activities (N=110) and teachers who do not have such experience (N=40) is carried out. The samples are equivalent in gender, academic titles and degrees, age, and work experience. The main advantages are the following: access to information at any convenient time; flexible schedule and the ability to organize independent work. Among the difficulties technical failures, lack of personal contacts, inconvenience of working with an electronic course and the need to spend a long time at the computer were noted. Teachers with experience in the development of e-learning courses rate work in an electronic environment much more positively, in contrast to teachers without experience who exaggerate the frequency of technical failures, point out the lack of technical and legal support, and the difficulties in monitoring assignments. All the teachers can be divided into “skeptics” and “enthusiasts” in relation to the acceptance of digital environment. “Enthusiasts”, unlike “skeptics”, have a positive attitude to innovations, believe that the educational process becomes more flexible and intense, emphasize the growth of student involvement and independence, individualization of training, support from management, colleagues, technical support, transparency of interaction. Most teachers with experience in using e-learning courses turned out to be “enthusiasts”. The groups of “enthusiasts” and “skeptics” do not differ in gender, age, and professional experience, which indicates the possible presence of “second order” barriers: pedagogical beliefs that prevent the acceptance of e-learning.
The Relationship of Readiness for Changes and Self-Organization among Teachers of Higher Education
Authors: Semenova N.A. , Pavlova S.A.
Published: September 2023

The relationship between personal readiness for changes as a psychological state that mobilizes personal resources and self-organization as one of the leading professional competencies of a modern higher education teacher is substantiated. The proposed assumption that readiness for change and self-organization have characteristic interrelations is substantiated. The materials of an empirical study obtained on a sample of teachers from different regions of the Russian Federation aged 30 to 70 years, with teaching experience from 3 to 50 years in the amount of 138 people are presented. The methods “Personal change readiness survey” PCRS (Personal change readiness survey) S. Rolnik, V. Hull, N. Heather, R. Gold (adapted by N.A. Bazhanova, G.L. Bardier); "Technological Readiness Index (TRI)" (A. Parasuraman, K. Colby) adapted by Yu.V. Khlopovsky; questionnaire "Diagnostics of the features of self-organization" (DOS) (A.D. Ishkov); author's questionnaire "Professional competencies of a teacher of higher education" were used. Empirical results indicate a low level of readiness for change and an increased level of self-organization indicators, where the indicator of goal-setting is most pronounced, and the least – correction. Conclusions are drawn about the positive relationship between readiness for change, self-organization and optimism, as well as the inverse correlation of these indicators with the level of discomfort that occurs when using various technical innovations in professional activities. The revealed interrelations of indicators of the studied phenomena allow us to most thoroughly approach the formation of a system of professional competencies of a modern teacher of higher education.
Eye Tracking Research On Learning Difficulties For Children With Hearing Impairments
Authors: Smirnova Y.K.
Published: September 2023

The article analyzes the specifics of the organization of the perceptual activity of preschoolers with and without hearing impairment with different forms of instruction in the learning process. A comparative study of a sample of children aged 4-6 years was carried out: typically developing and with sensorineural hearing loss after cochlear implantation. During the experiment, the combinations of verbal and non-verbal instructions were varied. During the training task, eye movements were recorded by a Pupil Labs mobile tracker in the form of glasses. When changing the forms of instructions in 4 series of the experiment, it was found that a measure of reducing visual attention in the learning process in children with hearing impairment is changes in the periods of fixations when they are focused on the regions targeted for the learning task (such as a form for completing the task, a sample, an adult's face) . In children with hearing impairment, during the learning process, a transformation of perceptual processes was recorded depending on the form of the instruction: whether fixation on non-target stimuli decreases, fixation occurs faster or slower, whether the cognitive complexity of information decreases, whether fixation will be longer in target areas, whether there is constant attention and shared attention with an adult. It is shown how a different form of instruction allows you to restructure the perception of a child with hearing impairment, focusing attention on the elements relevant to the task. Differences in the change in the perceptual activity of typically developing preschoolers and preschoolers with hearing impairment were analyzed with different forms of instruction. It was found that the movement of the eyes of children with hearing impairment, unlike their peers, can be characterized by a significant reduction in orienting perceptual actions. The most effective for children with hearing impairment is the simultaneous use of multimodal means of explaining instructions or separately non-verbal forms of instructions (showing an action or a sample). For typically developing children, non-verbal forms of instruction without verbal accompaniment are not as effective.

Authors: Sapega D.V. , Bogdanovich N.V.
Published: September 2023

The article is devoted to the study of the features of self-organization in adolescents with a revealed tendency to various types of deviant behavior, as well as the relationship between the development of self-organization and a tendency to deviant behavior. Relevance, novelty and practical significance are due to the poor knowledge of this topic and the prospect of developing practical methods for preventing deviant behavior through the development of self-organization. The empirical study involved 60 ninth grade secondary school students of both sexes (mean age 15 years). In the course of the empirical study, such features of self-organization of adolescents with a revealed tendency to deviant behavior were described as a low severity of the general level of self-organization and its individual components, and significant inverse correlations were found between the level of self-organization and a tendency to various types of deviant behavior.

Authors: Khavylo A.V. , Ustenko A.V. , Engalychev W.F.
Published: September 2023

The study is aimed at developing the problem of increasing the reliability and objectivity of professional selection. Psychodiagnostic methods used in professional selection have a common drawback: their result is quite easy to falsify. The purpose of the study is to explore the possibilities of psychophysiological methods in solving problems of psychological diagnostics. Hypothesis: the intensity of emotional and physiological reactions to stressful stimuli is positively related to the level of neuroticism and negatively to the stress resistance of the participants in the experiment. The sample consisted of students in the amount of 16 people (11 girls) aged 17 to 21 years. A modified Eysenck personality questionnaire and a test by Cohen and Willianson were used. The experiment consisted in presenting stressful video material to the participants and simultaneously fixing their mimic and physiological reactions. It was found that the intensity of the manifestation of the emotion of sadness is positively associated with low stress tolerance, and the severity of the emotion of happy is positively associated with the level of neuroticism (p<0.05). The revealed effects are both of applied importance in the context of professional selection, and are of independent theoretical interest.

Subjective Representations of the Health of Preschool Teachers
Authors: Volkova E.N. , Rudnova N.A. , Kalimullin A.M.
Published: September 2023

Objective. The study of subjective representations of the health of preschool teachers.
Background. Subjective representations of health are an individual psychological instrument of well-being influencing objective achievements in personal, social and professional life. Subjective representations of the health of preschool teachers are both an important factor for their professional activities and the characteristics of the educational environment for children. Research on subjective representations of the health of preschool teachers is important because it may affect the development of children's attitudes towards their health.
Study design. The study is dedicated to subjective representations of health and their relationship with stratification variables and components of psychological well-being in the PERMA model. Analytical approaches included descriptive statistics, frequency analysis, analysis of variance, cluster and correlation analyses.
Participants. The main sample included 1537 preschool teachers aged between 21 and 74 years with work experience from 1 year to 55 years, with secondary or higher education. All participants live in the Russian Federation.
Method. The study was conducted online using the PERMA-Profiler questionnaire, adapted for the Russian-speaking sample. Subjective representations of health include the cognitive self-assessment of health, satisfaction with own’s health, social comparison of own’s health with peers. The information about socio-demographic characteristics (age, level of education, work experience, place of residence, marital status, number of children) was also collected.
Results. The perception of the health of preschool educators consistent between own’s cognitive self-assessment of health, satisfaction with health and social comparison with the health of other people. Subjective representations of the health of preschool teachers are characterized by positivity and optimism. These representations do not depend on the level of education, place of residence, geography of the region of residence, number of children, marital status, but are related to age and work experience. The highest indicators of subjective representations of health were found among older educators.
Conclusions. Subjective representations of health have a positive connotation and are associated with the psychological well-being of preschool teachers. Involvement in pedagogical activity contributes to positive representations of the health of educators, especially in old age.
Socio-Psychological Programs: "Active Longevity" and "Anti-Aging XXI" – Evaluation of Effectiveness in Terms of Biopsychological Age
Authors: Berezina T.N.
Published: September 2023

Objective. Comparative analysis of the effectiveness of socio-psychological programs "Active Longevity" and "Anti-Aging XXI" in terms of their impact on biopsychological age.
Background. Against the background of the growing aging of the population of developed countries, as well as the ongoing pension reform, there is an increasing demand for the development of social programs to increase longevity and improve the health of older age groups.
Study design. For six months, a natural experiment was carried out, in which biopsychological age indicators were assessed in pensioners who participated in the "Active Longevity" and "Anti-Aging XXI" social programs and in the control group. Kruskal-Wallis statistics, Anova analysis of variance, Student's test for connected samples were used.
Participants. Pensioners attached to the site of the Moscow polyclinic: 345 people (272 women (55-70 years old, M = 62,8; SD = 4,45), 73 men (60-70 years old, M = 65,9; SD = 2,99).
Measurements. Tests for measuring biological age according to Voitenko, psychological age according to Abulkhanova-Berezina, expected retirement age.
Results. In the absence of supportive training, there was a natural increase in the biological age of pensioners in the control group (by 2,6 years for women in six months, and 0,2 years for men). Participation in the "Active Longevity" program led to the absence of significant aging, and the selection of personal resources through the "Anti-Aging XXI" program led to a significant decrease in biological age by 0,7 years, and the biological aging index by 1,1 years. 
Conclusions. 1) The effectiveness of using social health programs is higher for women than for men. 2) The greatest effect is achieved with a combination of programs. "Antiaging XXI" is used to select resources, and classes take place in the centers of Moscow Longevity.

Controllability of the Main Road with an On-Ramp Section in Freeway Traffic Flow
Authors: HAMİDOĞLU Ali
Published: September 2023

This study examines the controllability issue pertaining to the main road with a single on-ramp segment within the context of freeway traffic flow. In this regard, a finite-dimensional nonlinear model is formulated by integrating variable speed limit (VSL) and ramp metering (RM) techniques with the controllability property of the system derived under continuous VSL and RM controllers. This allows us to simultaneously control the density of the main line and reduce the queue density of the merging sector. In the numerical experiment, numerical simulations are conducted on a sample model of a main road to investigate the null controllability of the system and validate the theoretical findings. The numerical findings suggest that it is possible to achieve a consistent queue length for the on-ramp section through the implementation of suitable VSL and RM controls. Therefore, the primary accomplishment of this study is to effectively regulate the traffic flow on the main road segment by managing the density of vehicles within a specified timeframe while also considering the queue density of the on-ramp section
Secure Handover Management Against False Base Station Attacks
Authors: AMİRBEKOV Yerdos , BOZKAYA Elif
Published: September 2023

False Base Stations attack raises concerns about data privacy during handover process in 5G networks. Broadcasting of measurement reports unveils the need of security assessment since a false base station can send a stronger signal to the User Equipment (UE) to establish a connection with itself. This may cause to the leakage of information. Thus, a fundamental solution is to protect measurement reports with encryption algorithms. In this paper, we identify the security vulnerabilities of handover process and simulate a scenario, where a false base station is deployed and UEs can be connected it during handover process. In order to prevent this, we propose a secure handover scheme to protect measurement reports by using two encryption algorithms; (i) Advanced Encryption Algorithm (AES)-256, and (ii) Rivest Cipher 4 (RC4) Algorithm. Then, we analyze the computation time and show the secure connection to a legitimate base station during handover process.

Authors: İLOĞLU Onur , YURTSEVER Hüsnü Arda
Published: September 2023

Transparent ZIF-8/TiO2 nanocomposite thin films were prepared by a two-stage dip-coating method. TiO2 was first deposited on glass substrates by sol-gel dip-coating. Heat treatment temperature, number of layers and doping metal type/level were optimized in the first step. In the next step, ZIF-8 was grown by solvent based crystallization method on TiO2 layers. Cu, Ce, Fe or Zn doped TiO2 thin films were prepared in order to increase the photocatalytic performance of ZIF-8/TiO2 nanocomposite. The highest photocatalytic methylene blue degradation activities were obtained with the ZIF-8/TiO2 nanocomposite thin films prepared by using 1% Cu or 1% Ce doped TiO2 thin films as the substrates. Both films exhibited 19% dye removal in 1 hour under 254 nm LED light irradiation whereas the dye removal efficiencies were 36% and 29%, respectively, in 1 hour under 365 nm LED light irradiation.
Enhancing Motorway Exit Efficiency: Determining the Ideal Number of Toll Booths
Authors: AKSOY Göker
Published: September 2023

This study presents a model for determining the optimal number of toll booths at barrier-operated freeway exit toll booths in Istanbul, considering mixed traffic conditions and payment methods. In the past decade, Istanbul has experienced rapid growth in its road network due to public-private partnership (PPP) projects. However, despite relatively modest demand, long queues are frequently observed at the exit toll booths of newly constructed PPP freeways, which utilize barrier-controlled toll collection systems. These toll booths offer both electronic toll collection (ETC) and manual toll collection (MTC) options, with MTC users required to come to a complete stop for transactions, while ETC users experience reduced speeds. The presence of mixed payment methods leads to significant interactions between vehicles, resulting in longer service times and limited toll booth capacity. To evaluate the system, service times were measured considering four vehicle classes, payment methods of both the leading and serving vehicles, and whether the serving vehicle needed to wait for money exchange. The findings reveal a wide range of service times, varying from 2.21 seconds to 36.04 seconds, and toll booth capacities ranging from 168 to 1017 vehicles per hour per lane for different vehicle classes, with an increase in MTC utilization.
Freezing and Thawing Resistance of Hemp Fiber Reinforced Clays
Authors: KURT ALBAYRAK Zeynep Neşe , ÖZDEMİR Bahattin
Published: September 2023

Clays are natural soils. In geotechnical engineering, clayey soils are problematic because of their volume change properties when interact with water. Additionally, they may lose strength when exposed to freezing-thawing. Various soil improvement methods are used for modifying the clay soils properties. One of these methods is by adding natural fibers. The aim of study was to investigate the strength and freezing-thawing properties of a high plasticity clay (CH) with hemp fiber. For this purpose, fiber-reinforced clay samples were prepared by adding hemp fiber at different percentages (0.5%, 1%, and 1.5%) and different lengths (2 mm, and 5 mm) to a CH clay from Erzurum, Turkey, and the consistency, unconfined compressive strength (UCS), and freezing-thawing properties of the samples were investigated. Unconfined compressive strength of the samples increased with the increase in the hemp fiber percentage, and improvements occurred in their unconfined compressive strengths after freezing-thawing cycles, compared to unreinforced clay. According to the test results it is thought that hemp fibers could be an alternative for improving the freezing and thawing resistance of clay soils.

A produção de suínos confinados gera efluentes que quando aplicados no solo servem como fonte de fertilizante e quando aplicados sem tratamento adequado alteram a qualidade ambiental. Estes dejetos contêm elementos potenciais contaminantes cuja aplicação excessiva gera acúmulo de materiais e podem ocasionar efeitos tóxicos para as plantas, como na germinação de sementes. Neste estudo objetivou-se analisar o efeito de doses de dejetos líquidos de suínos (DLS) sobre a germinação de três culturas de grãos de interesse agrícola. Os ensaios foram realizados em condições de laboratório com sementes de soja, trigo e milho, que foram dispostas em placas de Petri, na quantidade de dez sementes por placa. Foram aplicadas doses tratamentos de DLS, caracterizado quimicamente, correspondentes a 0, 1,4 e 2,1 xDP (vezes a Dose Padrão) m³ ha-1 com três repetições. As placas foram colocadas na BOD em temperatura 24 0C. Os dados obtidos foram analisados pelo teste de Tukey (5%). Aos sete dias do início do ensaio foi determinada a porcentagem de germinação. O DLS possui em sua composição alguns elementos potenciais contaminantes, como o cobre, o zinco e o amônio, os quais podem ocasionar prejuízos na germinação de diversas culturas, sobretudo com exposição direta das sementes nas placas de Petri. As sementes de soja e trigo sofreram efeito negativo da aplicação de DLS apresentando redução na taxa de germinação com o uso de 1,4 e 2,1 xDP m³ ha-1. A aplicação do equivalente a 1,4 e 2,1 xDP m³ ha-1 de DLS não afetaram significativamente a germinação de sementes de milho.

Durante la crisis sanitaria provocada por la pandemia del coronavirus covid-19 y durante la declaración del estado de alarma se produjo una alteración en el ámbito competencial entre Estado y comunidades autónomas en materia sanitaria. En este trabajo se trata inicialmente un estudio sobre el alcance de dicho reparto competencial y las modificaciones que se produjeron durante los años 2020 y 2021. La materia sanitaria se incluye en el art. 149.1.16.ª CE, en virtud del cual el Estado tiene competencia exclusiva «sobre la sanidad exterior», sobre «las bases y coordinación general de la sanidad y sobre la legislación de productos farmacéuticos». Por su parte, las comunidades autónomas tienen competencias en el desarrollo legislativo y ejecución de la legislación básica del Estado en materia de sanidad interior e higiene, así como en la gestión de estas competencias, en la ordenación y establecimientos farmacéuticos, en lo relativo a la ejecución de la legislación del Estado en los productos farmacéuticos y, por último, en las instituciones, servicios sanitarios, y en lo que se refiere a la coordinación hospitalaria. En las competencias en materia sanitaria siempre concurrirían el Estado y las comunidades autónomas, aunque, en la gestión del estado de alarma, el Estado ha actuado con una posición prevalente. De hecho, las comunidades autónomas tienen un deber especial de colaboración y cooperación en la superación del supuesto de hecho causante del estado de alarma, de manera que el ejercicio de sus competencias debe sujetarse siempre a dicho deber.

Background

Access to neurology services is important for children’s well-being. We sought to evaluate the effects of telehealth on pedi­atric neurology appointment outcomes for children.

Methods

Using electronic health record (EHR) data, information about children with pediatric neurology appointments in a tertiary care children’s hospital in North Carolina was collected. Appointment outcomes (completion, cancellation, and no-show rates) were calculated for children who had a neurology appointment scheduled both in the pre-pandemic (March 10, 2019, to March 9, 2020) and pandemic (March 10, 2020, to March 9, 2021) periods. “Telehealth user” was a child who had at least one telehealth appointment scheduled between March 10, 2020, and March 9, 2021. In bivariate and multivariate analyses, we compared appointment outcomes for telehealth users and non-users.

Limitations

EHR data were limited to a single institution and could have missed children’s clinical encounters elsewhere. Since this study used secondary data that were not collected for research purposes, it is possible that there were unmeasured confounders. Because of the observational nature of the study, the association between telehealth use and appointment outcomes does not indicate causation.

Results

A total of 2110 children had 11,194 pediatric neurology appointments scheduled. Telehealth users compared with non-users were more likely to be White, non-Hispanic, have private insurance, and live farther from the children’s hospital. There was a statistically sig­nificant decrease in completion (66% versus 57%) and increase in cancellation (27% versus 33%) and no-show (7% versus 10%) rates in the pandemic when compared to the pre-pandemic period. In the pre-pandemic period, telehealth user and non-user groups had similar cancellation and no-show rates. In the pandemic period, there was a statistically significant decrease in cancellation and no-show rates in the telehealth user group when compared to the non-user group.

Conclusions

Pediatric neurology outpatient clinic visits decreased substantially during the pandemic. Telehealth mitigated these problems. Children belonging to a minority race/ethnicity are less likely to use telehealth, increasing their risk of poor access to neurology services.
Critical investigation of microchannel design effect on thermal performances of a PEM fuel cell

A major challenge for improving the characteristics of fuel cells is to obtain uniform tempera-ture distribution during its operation, in which a major part of hydrogen chemical energy is converted to heat. If not properly exhausted, this exothermic chemical reaction causes over-heating in the polymer electrolyte membrane fuel cells (PEMFCs), leading to a reduction in their performance. Hence, analyzing different techniques for PEMFCs cooling may be nec-essary for this kind of energy systems. In this study, four microchannel design effect on alu-minum oxide (Al2O3) nanofluids thermal behavior in cooling plates with 1400×1800 mm2 was investigated using computational fluid dynamic (CFD) simulation. The performances of proposed microchannel designs were evaluated in terms of maximum and uniformity tem-perature. The suggested study has been validated by available published results from previous research studies. The obtained results depicted that the maximum temperatures have been 305.3K and 305.5K for S- character flow field and two stages coolant flow field microchannel designs, respectively. The results revealed that the multi-flow plate designs might greatly en-hance the performance of PEMFCs in terms of temperature distribution in the cooling plate when compared to standard flow field designs. Another important finding was that the two stages microchannel and S-design are more thermal stable compared with other microchan-nels.

Sexual violence against children can have complex impacts, including physical and non-physical loss and suffering. Children who experience sexual violence need to be protected and recovered psychologically and socially. A form of legal protection for children as victims can be in the form of restitution charged to the perpetrator to fulfill the rights of children as victims. This research aims to find out how the implementation of the right to restitution for children as victims of criminal acts of sexual violence is implemented and how judges consider in making decisions that include requests for restitution for children as victims of criminal acts of sexual violence in the jurisdiction of the Bantul District Court. This research uses a type of juridical-empirical legal research and uses interviews and literature study as data collection techniques. There were 35 cases of criminal acts of sexual violence against children at the Bantul District Court from 2020 to 2022, but only 7 cases included a request for restitution against the victim in the prosecution, and there was 1 case where the judge rejected the request for restitution. In 6 cases where restitution was granted, the victim's right to restitution was not fulfilled because the defendant did not have the good faith to pay restitution.
