ABSTRACT BACKGROUND: Viral hepatitis is a global phenomenon, with the disease burden varying on a daily basis. Amongst chronic infections, hepatitis B virus and hepatitis C virus (HCV) are egregiously linked to severe health-related complications, with a worldwide prevalence of 248 million and 71 million respectively. Amongst the developing world, a hand full of countries are exhibiting a gross decline in chronic viral infection prevalence, like Bangladesh. While countries such as India have a consistent prevalence, Pakistan bears one of the largest proportions of chronic viral hepatitis globally with increasing trends shown year-by-year. Various old literature texts have stated an approximate national prevalence rate around 2.6% and 5.3% of hepatitis B and C respectively. OBJECTIVE: The objective of this study was to determine the current seroprevalence rates of chronic viral hepatitis amongst the general population of rural Sindh using a screening program to determine the current disease burden. METHODS: An observational, cross-sectional survey based on a screening program was conducted in 5 districts with a combined population of over 6.5 million. The screening was carried out via the administration of various camps with the assistance of local social workers and welfare organizations. A total of 24,322 individuals met the inclusion criteria and were screened through (HBsAg/HCV) rapid test cassette (WC) Imu-Med one-step diagnostic test. RESULTS: Hepatitis B was found positive in 964 (3.96%) individuals including 421 (43.67%) males and 543 (56.32%) females, while hepatitis C was positive in 2872 (11.80%) individuals including 1474 (51.32%) males and 1398 (48.67%) females. The prevalence amongst the districts varied between 0.97% and 9.06% for hepatitis B, and 1.61% and 29.50% for hepatitis C, respectively. Umerkot was found to be the most prevalent district amongst rural Sindh, while Badin had the least number of seropositive people. The second most prevalent district of the study population was found to be Tando Allahyar followed by Mirpur Khas. The combined seroprevalence of 15.76% was calculated for hepatitis B and C together amongst the five studied districts of rural and peri-urban Sindh. CONCLUSION: The alarmingly high prevalence rates revealed in our study warrant the urgent need to generate multiple effective strategies in the region to enhance awareness amongst the general population regarding screening, prevention, and prompt treatment of the disease.

Authors: ROSEVICS Leticia , RAMOS JÚNIOR Odery
Published: July 2021

ABSTRACT BACKGROUND: Ileitis is defined as ileal inflammation, with several etiologies, including inflammatory bowel disease (IBD), and can be evaluated during the colonoscopy exam, but its mandatory evaluation is discussed, because of few diagnosis and procedure time. OBJECTIVE: This study aims to evaluate the correlation of colonoscopic ileitis with the clinical presentation, in order to identify the cases where ileal examination is mandatory. METHODS: A retrospective, cross-sectional study was conducted between 2013 and 2017. The examination report, indications for colonoscopy, and medical records were evaluated in order to identify whether the colonoscopic findings were clinically significant. Patients over 18 years of age who had undergone ileoscopy were included, whereas patients below 18 years of age, those with previous intestinal resections, and repeated examinations of the same patient in the study period were excluded. The estimated association measure was the odds ratio with 95% confidence intervals. P-values <0.05 indicated statistical significance. RESULTS: A total of 3382 cases were included. Among these participants, 64.5% were females and the average age was 56.9±13.1 years (18-89 years). Ileal alterations were observed in 5.3% of the patients, with 2.69% being clinically significant between all patients, and 0.96% excluding those with IBD. There was a positive correlation between the ileitis findings and IBD control examinations and a negative correlation in screening and change in bowel habit indications. Among the indications with ileitis clinically significant, IBD control still had a positive correlation, ‘diarrhea’ and ‘others’ did not show a statistical significance, and all other indications presented a negative correlation for ileal assessment. CONCLUSION: Ileal evaluation in only mandatory in IBD control. When the main colonoscopy objective is detecting colonic neoplasms, ileoscopy is unnecessary.

Published: July 2021

The study aims at defining and characterizing a specific restoration mortar for archaeological masonry structures made with traditional materials and to assess the suitability of the mixture compared to other mortars; such a goal is crucial to develop and define interventions in the archaeological sites. The mixture was defined to ensure compatibility with ancient materials and following frequently adopted recommendations at the site, specifically by using: (1) raw materials as similar as possible to the ancient ones; (2) traditional mix design. Therefore, the mixture was made with commercial lime putty CL 90-S type and natural Phlegrean pozzolan, i.e. volcanoclastic material collected from the volcanic area located in the West of Naples in Italy. The precious and limitedly available natural pozzolan used in the experiments resulted in an exclusive mortar which is very similar to the archaeological ones. The mortar has a binder to aggregate ratio 1:3 by volume, according to traditional techniques typically encountered in the ancient Roman city of Pompeii and Vesuvius surrounding area. The evolution of the flexural and compressive strength, elastic modulus, bulk density, open porosity and ultrasonic pulse velocity has been monitored for up to 200 days, based on standard procedures. Moreover, the hardening process was monitored with Differential Thermal Analysis up to 90 days, through the evaluation of phase transitions associated with dehydroxylation and decarboxylation, considering different depths from the external surface of the mortar. The achieved mechanical properties were compatible with those of lime-based mixtures for repair interventions of ancient masonry structures. Moreover, the mortar was found to be well-suited to mitigate cracking, showing a low ratio between its stiffness and load capacity compared to other typologies of mortars used for masonry restoration. Ultrasonic pulse velocity test proved to be a reasonable complementary method to monitor the evolution of the hardened properties of the mortar. Carbonation was found to be still progressing at 90 days. The data presented provide useful and reliable information to approach the complex process of restoration in archeological sites.
Earth pressures mobilised in dry sand with active rigid retaining wall movement
Authors: Deng C. , Haigh S.K.
Published: July 2021

A series of centrifuge tests was conducted to explore the earth pressures mobilised in loose and dense sand for a complete set of active movement modes of a rigid retaining wall: rotation about the base, translation and rotation about the top. Earth pressures behind the wall were measured by a Tekscan pressure mapping system. This paper reveals that earth pressures at all depths decrease simultaneously with active wall rotation about the base, while those in shallow layers can increase with active wall translation and rotation about the top. A linkage between earth pressures and shear strains was built as a simplified constitutive law, together with deformation mechanisms, allowing designers to predict flexible wall deflections during construction as well as ultimate collapse.
Filter paper method for suction measurement using electrical resistivity

Published: July 2021

The filter paper method is an economical, easily accessible, and simple-to-use method to measure total or matric suction over a wide suction range. Difficulty in handling the filter paper can result in inaccurate water content determination of the filter paper leading to poor estimation of the suction. This paper examines the feasibility of using electrical resistivity of the filter paper in the non-contact mode to determine equilibrium time and to infer the total suction. It was shown that for a specific set-up, electrical resistance (ER) can be used in place of electrical resistivity. Relationships between ER and water content of the filter paper and between ER and total suction were first established. Finally, a prototype set-up is used to demonstrate how it can be used to measure the total suction of soil specimens. It was demonstrated that ER of the filter paper can be used to provide a reasonable estimate of total suction greater than 100 kPa with an error between −18 and +10%. Better accuracy can be achieved if each filter paper is calibrated before use.

Authors: Oh Kyung Seo , Lee Seung Young , Min Se-Hee , Ryu Choongun , Shin Hwa-Yong
Published: July 2021

Hypertrophic osteoarthropathy (HOA) is a rare clinical condition including an abnormal periosteal reaction in the long bones that causes painful swelling and tenderness of the extremities, digital clubbing, arthritis, synovitis, and joint effusions. Most cases are associated with tumorous conditions and most commonly with lung cancer. HOA has been rarely reported in association with other cancers. A patient with a history of recurrent renal cell carcinoma was referred to our clinic with bilateral leg pain, knee joint effusion, and arthritis. Simple radiography and bone scintigraphy confirmed a diagnosis of HOA. Oral non-steroidal anti-inflammatory drugs, joint fluid aspiration, and intra-articular injection of pain medications were found to be effective in the management of HOA pain. HOA prognosis depends on the underlying disease, therefore, cancer treatment is critical. This case demonstrates the need to consider HOA in patients with various malignancies who present with bone or joint pain of the extremities.

Published: July 2021

Background: Patients with chronic liver disease (CLD) planned for liver transplantation (LT) often show severe thrombocytopenia, but there is a lack of evidence in deciding the threshold for prophylactic platelet transfusion.Case: A 47-year-old women with acute liver failure was referred for LT. Despite daily transfusion of platelets, platelet counts remained under 10,000/µl. During LT, 2 units of single donor platelets (SDP) were transfused. Although platelet counts remained extremely low (3,000–4,000/µl) no diffuse oozing was observed and the blood loss was 860 ml. Postoperatively, there was no sign of active bleeding or oozing, and the patient received only 1 unit SDP transfusion.Conclusions: CLD patients may have severe thrombocytopenia. However, primary hemostasis may not be significantly hindered due to the existence of rebalanced hemostasis. Prophylactic platelet transfusion in these patients should not be decided based on platelet counts only, but also take other coagulation tests and clinical signs into consideration.
Repeated endotracheal tube cuff tears during nasotracheal intubation due to nasal cavity orthodontic micro-implant - A case report -
Authors: Seo Su Hyun , Lee Jun Mo , Lee Je Jin , Ahn Eun Jin , Choi Geun Joo , Kang Hyun
Published: July 2021

Background: Nasotracheal intubation is generally performed for intraoral surgery.Case: A 34-year-old female patient who underwent orthognathic surgery exhibited repeated endotracheal tube cuff tears during nasotracheal intubation. After intubation, leaks developed, and torn endotracheal cuff was observed in the removed endotracheal tube. Subsequently, re-intubation through the same nasal cavity was performed immediately, but leakage from the torn endotracheal tube cuff was re-observed. A leakage test of the extubated tube revealed air bubbles and leaks near the tube cuff due to the tear. Nasotracheal intubation was performed through the other nasal cavity, and there were no leakage findings or abnormalities. During the course of the surgery, the surgeon noticed that the orthodontic micro-implant deposited in the mid-tube cavity was exposed to the nasal cavity. Conclusions: We aimed to emphasize caution and discuss the possibility that orthodontic micro-implants that are not confirmed during preoperative evaluation may cause repeated endotracheal tube cuff tears.

Published: July 2021

The purpose of this study is to understand consumer experience of using mobile delivery app services and explore the constructs and elements of mobile app service quality. This study applied focus group interviews, a qualitative research method. Two sessions of focus group interviews were conducted from April 8 to April 9, 2019, and the interview scripts were analyzed. As a result, a total of 42 concepts were extracted, classified into 8 subcategories, compressed into 4 categories, and grouped into 2 dimensions. 'Service quality' dimension consists of two categories: 'platform operation quality factor' and 'platform system quality factor'. 'Platform operation quality factor' was composed of 'food delivery service' and 'store management' subcategories. 'platform system quality factor' was composed of 'user-friendly UX/UI' and ‘usefulness of personalized information' subcategories. 'Motivation/constraint' dimension consists of two categories: 'mobile delivery app usage motivation factor' and ‘mobile delivery app constraint factor’. ‘mobile delivery app usage motivation factor’ was composed of ‘user characteristics’ and ‘distribution channel characteristics’ subcategories. ‘mobile delivery app constraint factor’ was composed of ‘delivery service perspective’ and ‘platform ecosystem perspective’ subcategories. Theoretical implications of this study suggest that previous perspectives of consumer behavior models need to be re-examined when understanding consumer experiences of using mobile delivery app services. Result also imply that the service quality of the mobile delivery app should be managed and controlled both by platform management and system management perspectives.
A Phenomenological Understanding on the Meaning of Operating Korea Noble House Stay: Applying the concept of struggles for recognition
Authors:   The Tourism Sciences Society Of Korea, Cho Ok-Seon , Kim Hyoung-Gon
Published: July 2021

This study aims to understand the meanings the operators of Korean Noble Houses have of running these unique homestays. A total of eleven operators, who directly own and manage Korean noble houses (homestay houses) participated in the study through an in-depth interview. The interview transcripts were analyzed through applied thematic analysis. The concept of struggle for recognition Honneth(1992) theorized was introduced to better understand the phenomenon in this study. The results show that the operators experienced positive feelings of gaining recognition through their interactions with visitors as well as receiving a certain degree of economic benefit helping them maintain their traditional houses. The acquisition of positive self-worth gained through operating these accommodations tend to provide them a sense of power, satisfaction, and pride. However, a sense of disrespect also emerged as a major theme from these interviews, which acts as an underlying driver for recognition. These results are in line with Honneth's (1992) theory of the struggle for recognition in which an individual is described as one who possesses a desire to be recognized positively by others through a process of mutual recognition. Several theoretical and practical implications are suggested in relation to operating Korean Noble Houses from the perspective of the struggle for recognition.

Published: July 2021

The article is devoted to the history of the study and teaching of the Even (Lamut) language in Russia in the period from the 17th – to the beginning of the 21st century. Special attention is paid to the problem of linguistic ecology. The fundamental and applied researches in the synchronic and diachronic aspects, as well as issues of teaching the Even language in families, pre-school educational institutions, colleges and higher educational institutions of Russia are studied. Ethnolinguistics is considered as a possible tool of language preservation and development, i. e., the Even language teaching in the close connection with traditional and modern material and spiritual culture. In this way, the role of vocabulary reflecting the song and dance creative activity, decorative and applied art, ceremonies (of life cycle: birth, wedding, funeral) and economy (hunting, fishing, reindeer breeding), taboo and euphemisms, folk knowledge (metrology, meteorology, space orientation, medicine, calendar, food and cuisine, etc.), as well as the words of religious beliefs (animism, shamanism, Christianity) in the formation of a language picture of the world and the Evens’ mentality is being determined. The role of state institutions, civil society organizations, as well as the members of small-numbered ethnic groups per se in the preservation and development of their language and culture is described. The attention is paid to the translation as the tool of a unique language preservation

The article analyzes the originality of the ethnocultural dynamics of the Krasnoyarsk Territory in the context of artistic practice. The general dynamics of ethnic groups inhabiting the Krasnoyarsk Krai from the early 17th century to the early 21st century is shown. At the same time, within the framework of this dynamics such stages pre-Soviet, Soviet and post-Soviet were identified. A general characteristic of the creativity of Krasnoyarsk artists who worked in the selected periods is given. Within the framework of the philosophical and art history analysis, the works of D. I. Karatanova, Yu. P. Ishkhanov and S. E. Anufrieva as the most representative for each period and, at the same time, allowing to consider creativity in its various forms (painting, sculpture and ceramics) were selected and studied in detail. As a result, it was concluded that these works most clearly reflect the changes of a person living in these territories and his/her relationship with nature and historical roots

Authors: Grabowski Paweł , Jankowiak Artur , Marowski Witold
Published: July 2021

Opencast mining machinery represents a group of large-scale individually manufactured technical objects operated with long-life requests. Since their manufacturers are obliged to provide product that will reach declared time of life, fatigue strength and durability conditions have to be taken into account for superstructures to meet the requirements. The paper highlights main problems occurring while assessing fatigue lifetime during design. Firstly, the short survey of current state of the art regarding the approach to this problem is presented. Secondly, the most important reasons of unsatisfactory accuracy of the assessments are discussed. As a main objective of the study, the authors introduce the unique method of continuous fatigue lifetime correction for the welded superstructures during the machine lifecycle, as a remedy for this group of machinery. Furthermore, results and experience from adapting the approach in real object are presented, including fatigue lifetime correction due to the real intensity of loading acquired from a bucket-wheel excavator during its longlasting operation. It is expected that proposed procedure can help to improve credibility of fatigue lifetime assessment of heavy earthmoving machinery.
Study on the temperature and strain fields in gas foil bearings – measurement method and numerical simulations
Authors: Zdziebko Paweł , Martowicz Adam
Published: July 2021

Gas foil bearings belong to the group of slide bearings and are used in devices in which operation at high rotational speeds of the shafts are of key importance, e.g., in gas turbines. The air film developed on the surface of the bearing’s top foil allows this structural component to be separated from the shaft. This ensures a non-contact operation of the bearing. In the case of the mentioned type of bearings, their resultant operational properties are influenced by both thermal and mechanical phenomena. The current work presents a model of a gas foil bearing developed making use of the Finite Element Method. The model takes into account thermomechanical couplings which are necessary for the correct simulation of the operation of physical components of the modeled system. The paper reports the results of numerical analyzes conducted for the elaborated model as well as the relevant conclusions concerning thermomechanical couplings present in gas foil bearings. The method for the experimental identification of the temperature and strain fields in the bearing’s top foil proposed to validate the numerical model is also presented.

Published: July 2021

O propósito deste estudo foi analisar se as distorções físicas influenciam o senso de utilidade que o consumidor tem dos produtos e, consequentemente, a percepção do que pode ou não ser reciclado. Por meio de uma pesquisa experimental, junto a estudantes de duas universidades localizadas no Sul do Brasil, foram realizados testes em grupos separados - com e sem distorção de produto (papel recortado e não recortado), a fim de verificar se a distorção interferiu no local de descarte do material (lixo reciclável e não reciclável). Em ambas as configurações, constatou-se que a maior parte dos materiais foi descartada no lixo reciclável. Este artigo confirma a teoria ao evidenciar que quanto maior for o senso de utilidade de um produto, maior será a sua classificação como “resíduo reciclável” durante o descarte. Os dois grupos (o que cortou, e o outro, que não cortou os papéis) perceberam a grande utilidade do material, descartando-o no lixo reciclável. Também foi possível afirmar que há diferença significativa entre os resultados de descarte encontrados entre mulheres e homens. De forma geral, as mulheres possuem uma decisão mais sustentável do que os homens; em relação ao senso de utilidade das mulheres e dos homens, não houve diferença significativa. ABSTRACTThe study purpose was to analyze whether physical distortions influence the consumer's sense of utility of products and, consequently, the perception of what can or cannot be recycled. Through experimental research, with students from two universities located in the south of Brazil, tests were carried out in separate groups - with and without product distortion (cut and uncut paper), in order to verify if the distortion interfered in the material disposal site (recyclable and non-recyclable waste). In both configurations, it was found that most of the materials were discarded in recyclable waste. This article confirms the theory by showing that the greater the sense of usefulness of a product, the higher its classification as “recyclable waste” during disposal. The two groups (the one that cut, and the other, that did not cut the papers) realized the great usefulness of the material, discarding it in recyclable waste. It was also possible to state that there is a significant difference between the disposal results found between women and men. In general, women have a more sustainable decision than men; in relation to the sense of usefulness of women and men, there was no significant difference.

Unlocking Rural Economy Growth through Digital Economy: Study Of Online Payment Acceptance Among Rural Retailers In Kelantan.
Authors: Karnadi Lydia , Kurniawan Yohan
Published: July 2021

Digital economy has become an essential key to unlocking rural economic growth in Malaysia with the launch of the Malaysia Digital Economic Blueprint (MyDIGITAL) by the government in February 2021. Online payment is a vital component of the digital economy and should be feasible even in rural areas since more than 80% of rural households had access to mobile broadband in 2019. Nevertheless, many are still using cash-based payments to make purchases. Thus, this study aims to observe online payment acceptance, particularly in Kelantan, from the rural retailers’ perspective. The Unified Theory of Acceptance and User of Technology (UTAUT) was applied by observing three determinants of behavioural intention to adopt online payment and a quantitative research method, i.e. questionnaire distribution via social media (Facebook) to 384 respondents, was used. The results were analysed using descriptive analysis, reliability test, and Pearson’s correlation analysis. Among the three variables examined, only two significantly affected rural retailers’ behavioural intention to adopt online payment, namely security and performance expectancy. With this information, the government could prepare more targeted, proactive design interventions (e.g., training, marketing, etc.) for rural retailers who are reluctant to use online payment. Hopefully, this research can help online payment services offered in rural areas and the implementation of MyDIGITAL to unlock rural economic growth. Besides, the aim is to inspire future researchers to continue this study with more extensive and complex research.

Published: July 2021

Effects of substitution of the Strontium atoms with smaller Calcium atoms on the structural features of the Ruddlesden-Popper SrLa2Sc2O7 two-slab compound is established. The crystal structure of orthorhombic Sr0.85Ca0.15La2Sc2O7 phase with maximum degree of substitution was determined by the Rietveld method (Fmmm space group, a = 0.5766(2) nm, b = 0.5743(2) nm, c = 2.0522(7) nm). Comparison of the structural features of SrLa2Sc2O7 and Sr0.85Ca0.15La2Sc2O7 shows that such type of substitution leads to a decrease in the (La,Sr)2 - О2 interblock bond length (from 0.222 (2) nm at x = 0 to 0.215 (1) nm at x = 0.15). The decrease in interblock bond length brings the constitution of the two-dimensional structure Sr1-хCaxLa2Sc2O7 closer to the structure of the three-dimensional perovskite, leads to its instability at х > 0.15 and gives a reason to conclude that this factor causes a limitation of region of the Sr1-хCaxLa2Sc2O7 solid solutions with a slab perovskite-like structure. Presence of such structure changes is the precondition for regulation of structural-dependent features of the materials on the base of scandates alkaline-earth and rare earth metals.

Authors: Kotova Natalia , Ivanov Michael , Usenko Natalia
Published: July 2021

Partial and integral enthalpies of mixing of the ternary Ag–Ca–Ge melts were determined for the first time by the high-temperature isoperibolic calorimetry at 1300–1550 K. The experiments were performed for six sections with a constant ratio of two components up to the molar fraction of the third component equal to 0.3. The enthalpies of mixing in this ternary system are exothermic values which increase in absolute value from the Ag corner of the concentration triangle towards the constituent binary Ca–Ge system. The minimum value of the integral enthalpy of mixing was obtained for Ca0.6Ge0.4 composition of the Ca–Ge binary system (about –58.00 kJ mol–1). The enthalpies of mixing of the ternary Ag–Ca–Ge melts are calculated for the whole concentration triangle by the Redlich-Kister-Muggianu method, taking into account the term of specific ternary interaction defined from our experimental data. The topology of the isoenthalpies of mixing is determined.

Published: July 2021

Fused chromones are attracting increasing attention as novel therapeutic agents due to their wide distribution in nature, effective bioactivities and low toxicity. 6-Carbonyl-7-hydroxychromones proved to be versatile synthons for the synthesis of linear hetarenochromones by annulation of heterocycle to the chromone core. The present review is focused on the syntheses of furo[3,2-g]chromones, pyrano[3,2-g]chromones and some of their N-containing analogues, namely chromeno[6,7-d]isoxazoles, pyrano[3’,2’:6,7]chromeno[4,3-b]pyridine-5,11-diones and pyrano[3’,2’:6,7]chromeno[4,3-c]pyridine-5,11-diones based on the 7-hydroxy-6-formylchromones or 7-hydroxy-6-acetylchromones and shows the current state of research to date. The methods for the synthesis of the starting 7-hydroxy-6-formylchromones and 7-hydroxy-6-acetylchromones have been also mentioned. The biological activity of naturally occurring and modified synthetic linear hetarenochromones has been also represented.
Individual Attitude towards Protective Behavior during COVID-2019 Pandemic in Adult Population
Authors: Bayramova Y.V. , Rahimova A.G.
Published: July 2021

Objective. Analysis of the link between intention to follow recommendations for protective behavior in the case of Covid-19 pandemic and individual attitudes toward the situation, normative beliefs and behavior of referent group, anticipated affect and perceived behavioral control.
Background. In the situation of the coronavirus pandemic, which is widespread ubiquitously, people have to inevitably and quickly change their lifestyle. These changes are closely linked to economic, social and existential uncertainty. In this regard, it becomes necessary to identify the facilitating and inhibiting factors for adaptation to required forms of behavior in society (rules of social distancing and seeking medical care).
Methodology. The methodological rationale for the research was a positive constructivist view of individual behavior. On the basis of the Theory of Planned Behavior the questionnaire “Protective behavior in the context of the COVID-19 pandemic” was developed.
Study design. The survey method was applied through online-forms of questionnaires in Azerbaijani and Russian languages. The regression model of following the protective behavior was tested separately for each language group.
Participants. The study involved 56 Russian-speaking and 68 Azerbaijani-speaking residents of Azerbaijan (social networks users).
Results. The reliability of the questionnaire was tested and a regression model was created to explain protective behavior. Differences in individual attitudes and subjective norms that determine protective behavior for Russian-speaking and Azerbaijani-speaking citizens are shown. The general role of past experience (duration of adherence to the quarantine regime) in consolidating protective behavior for both groups was determined.
Conclusions. Individual attitudes and normative beliefs define protective behavior in different ways among Russian-speaking and Azerbaijani-speaking citizens. An assumption has been made about the defensive nature of following the protective behavior as a decrease in anxiety in connection with future uncertainty. The results of the study reveal the peculiarity of following the protective behavior of a specific sample of respondents — people of the middle class of early adulthood, which limits the possibility of generalizing the conclusions to other age and socio-economic groups.
Prevalence of Violence Estimation in Russia through a Retrospective Youth Survey
Authors: Volkova E.N. , Volkova I.V. , Isaeva O.M.
Published: July 2021

Objective. Estimating the prevalence of violence among children born in Russia in the 1980s, in the early 1990s and in the late 1990s using a retrospective youth survey.
Background. Assessing the prevalence of a child abuse is an unresolved scientific and methodological problem. There are disagreements in approaches to assess the prevalence of violence, in interpreting the results. However, the main problem is the problem of reliable measuring instruments. Many studies show a wide variability in estimating prevalence and even in compared parameters; even greater discrepancies arise when it comes to identifying the factors and consequences of child abuse. Such a wide variability of estimation is associated with the insufficient quality of the measuring instruments and research procedures themselves.
Study design. The sampling analyzed data on the prevalence of violence among “post-Soviet children”, “children of the 90s” and “children of the 21st century”. The presence and nature of the relationship was checked using methods of mathematical statistics (correlation analysis and analysis of the significance of differences).
Participants. The study sample consisted of 537 people aged 18 to 24 years (M=20.23, SD=1.84) living in the Russian Federation. The 2006 sample of respondents included 144 people (25,7% of boys, 74,3% of girls), 2012 — 203 people (36,4% of boys, 63,6% of girls), 2018 — 190 people (35,7% of boys, 64,3% of girls).
Measurements. International Questionnaire ICAST-R (ICAST-Retrospective) (adapted by E.N. Volkova, O.M. Isaeva).
Results. A comparative analysis of the prevalence of violence among “children of the 21st cen¬tury”, “post-Soviet children” and “children of the 90s” showed that there is more similarity between these groups than differences in the severity of types, forms of violence and their frequency of occurrence (with the exception of cases of sexual violence, the percentage of cases of which is significantly reduced from the 2006 study to the 2018th year).
Conclusions. A retrospective survey of young people using ICAST-R allows you to assess the prevalence of violence among children, as well as the state of the child protection system from violence and the content of public perceptions regarding child abuse.

Destructive Speech Behavior in the Digital Environment: Factors that Determine the Negative Impact on the User’s Worldview
Authors: Galyashina E. I. , Nikishin V. D.
Published: July 2021

Today, in the context of universal digitalization and informatization of the society, the Internet environment is becoming a criminogenic communication environment, favorable for the commission of "speech crimes", i.e. speech actions that form the objective element of the corpus delicti. The paper is devoted to the criminological analysis of the factors that determine the negative impact of information threats on users of the digital communication environment (primarily, the Internet environment). Based on monitoring social communication in the Internet and analyzing the patterns of language functioning in conditions of the Internet communication, the authors summarize the main properties of the Internet communication and factors that provide the possibility of abuse of rights (freedom of speech and the right to freely search, receive, transmit, produce and distribute information) in order to have a destructive impact on the ideological safety of Internet users (primarily children and young people). Such factors include simulation, virality, hyperreality, the phenomenon of social disinhibition, etc. Particular attention is paid to the concept of destructiveness of information impact, considered on the basis of an analysis of the phenomena of human destructiveness, aggression and cyber aggression, deviance and delinquency. The authors propose to treat content risks and communication risks as forms of representation of destructive speech behavior in the digital environment as information threats to the ideological security of the Internet communication. The paper provides the authors’ classification of the information risks under consideration based on a generalization of judicial and forensic practice (including cases when materials were included in the Federal List of Extremist Materials by court decisions), the practice of the Federal Service for Supervision of Communications, Information Technology and Mass Communications (Roskomnadzor), as well as interdisciplinary analysis of scientific publications. The authors suggest that the terms "mortilatrya" and "eridophobia" be introduced in the context of ensuring the worldview security. The authors of the paper analyze the influence on the axiosphere of the Internet user of delinquent subcultures that erode a person’s identity in order to impose a new pseudo-correct- identity.
On Some Issues of Source Assessment in the History of Political and Legal Doctrines: Competition of Different Approaches
Authors: Kornev A. V.
Published: July 2021

The paper is devoted to a little-studied problem, namely, source assessment in the history of political and legal doctrines from the perspective of the competition of different approaches. In this paper, sources refer to various forms of theoretical knowledge: views, doctrines, theories, concepts, ideas, schools, trends and approaches. In other words, we consider the types of sources in which thinkers of different eras and trends try to reflect the essence of state legal phenomena, primarily, the state and law, and other closely related institutions, such as power, property, democracy, the rule of law, etc. One of the main ideas of the paper is to justify the fact that the history of doctrines is primarily the evolution of the struggle between them. Moreover, the opposition of ideas is actually observed from the very beginning of political and legal thought. The problem of an objective assessment of the doctrines is highlighted, since there are many factors that prevent this. In this regard, we consider the time (chronological), methodological, ideological, political, scientific, ideological and other circumstances, including individual preferences. The assessment is based on the main form of theoretical political and legal knowledge, i.e. a doctrine and its structure. It is the structural elements of political doctrine that are evaluated by researchers of ideas, who themselves are not always free in their expert activities. This aspect is also reflected in the paper.

The author summarizes: since the history of ideas is a history of struggle, competition in their evaluation is inevitable. It is possible to adhere to various philosophical views, but it is impossible to neglect the scientific validity of the teaching that is subject to evaluation. At the same time, this problem does not concern the doctrines that are being evaluated, but the personality of the evaluator of the doctrines, sometimes formed by the greatest thinkers.
