A Multi-orientation System for Determining Angular Distributions of Shear Wave Velocity in Soil Specimens
Authors: Basson Mandeep Singh , Martinez Alejandro
Published: January 2023

Soils typically have anisotropic mechanical and hydraulic properties due to the micro-scale interactions between particles that are influenced by particle morphology and depositional processes that can lead to particular particle arrangements (i.e., fabric anisotropy) and by imposed loading conditions and history (i.e., stress anisotropy). Experimental assessment of the anisotropy of soil specimens is a challenging feat, typically accomplished using specialized geotechnical testing and imaging equipment. The anisotropy of soil specimens can also be assessed based on measured responses, such as the velocity of propagating shear waves. This paper presents the development of a system that enables the measurement of shear wave velocity (VS) along different orientations and polarization planes using seven pairs of piezoelectric bender elements (BEs) to obtain angular distributions of VS. Specimens of glass beads and angular natural sands were tested in isotropic and one-dimensional (1D) compression to demonstrate the results obtained with the multi-BE system. The experimental results indicate that the effects of fabric and stress anisotropy can be identified by the angular distributions of VS, as well as measurements obtained along different polarization planes (i.e., VS,HH, VS,HV, and VS,VH). The level of anisotropy in soil specimens can be quantified either in terms of ratios of shear wave velocities or of parameters used to fit the angular VS distribution. The results also show that the parameters describing the relationship between VS and mean effective stress depend on the orientation of the propagating wave. The proposed system may enable the nondestructive assessment of soil specimen anisotropy using conventional laboratory equipment, which would complement other sophisticated experimental methods such as X-ray computed tomography and particle-based numerical simulations.
Općina Lovinac u socijalističkom razdoblju 1945. – 1991.
Authors: Brlić Ivan
Published: January 2023

The second half of the 20th century has been characterised by a very turbulent and rough historical background of Lika. One of the areas that was especially damaged is the area of Lovinac’s county. Tragic events as well as painful human destinies caused by the Second World war have been a part of the negative social and economic starting points of re-development of the community. In Lovinac and its surrounding there has not been needed economic nor any planned development; on the contrary, those times were characterised by the weak industrial production, low agricultural profit and significant and permanent depopulation. As a part of then Gračac’s county, Lovinac has been strucked by another plight – the Homeland War.
Prilog povijesti javne rasvjete i elektrifikacije Gospića
Authors: Šulentić Vladimir
Published: January 2023

The paper presents the chronological development of public lighting and electrification of Gospić in the period from the middle of the second half of the 19th century until the decade after the end of the Second World War when the energy network of Gospić was fitted into the state distribution system. The beginnings of public lighting in Gospić with the technology of kerosene lamps was recorded in the last years of the Croatian Military Frontier, and it remained in such a form for half a century. The context of public lighting in the social life of Gospić was analysed, as well as the complex political situations due to which Gospić lagged behind in other areas, especially in terms of technology. Special attention is given to the period of the 1920s, when electricity finally came to Gospić, and with it modern light. In 1925, the Municipal Lightning Plant Gospić was put into operation, and the fact that the first reconstruction was carried out after only four years shows how much the population needed electricity. As such, the plant was in use until the mid-1950s when Gospić received a new diesel thermal power plant, which operated for a very short time due to expensive electricity production. With the founding of „Elektrolika Gospić“ in 1956, a unique company for the distribution of electricity in the Lika area, and the completion of a five-year project to build a series of transmission lines, Gospić finally in 1961 got a modern and secure source of electricity.
The impact of sarcopenia on the postoperative outcome in colorectal cancer surgery
Authors: Benedek Zalán , Coroș Marius Florin
Published: January 2023

Background and aim. Malnutrition-induced sarcopenia predicts poorer clinical outcomes for patients with cancer. Postoperative complications such as wound infection, anastomotic leak (AL), cardiorespiratory events are the most frequent and devastating postoperative complications in colorectal cancer surgery and are frequently associated with malnutrition.

Methods. We reviewed the recent available literature to assess the relationship between the patient nutritional status and sarcopenia in colorectal surgery. The PubMed database was searched for publications. The included studies were original articles, prospective and randomized trials, clinical, systematic reviews and meta-analyses. The information was structured in a narrative review form.

Results. A simple method to assess malnutrition is to define the presence of sarcopenia (skeletal muscle mass reduction and modified composition) by radiological image analysis. Quantifying the material composition and quality is a novel method in patient-specific therapy. This could be a new perspective in colorectal surgery to reduce postoperative mortality, improve surgical planning, and enhance clinical outcomes. A few recent studies have objectively investigated the presence of sarcopenia in colorectal cancer and its impact on morbidity and mortality, but sometimes the results are contradictory.

Conclusion. There is evolving research to find the most appropriate management method , surgeons must be aware of the existence of sarcopenia to identify this risk factor in the occurrence of postoperative complications in colorectal cancer surgery.
Diachronic and synchronous manifestations of feminization in Ukrainian medical terminology
Authors:   Vasyl Stefanyk Precarpathian National University, Brus Mariіa
Published: January 2023

This article deals with the female profession names afterthe medical activity in their diachronic and synchronous manifestations. This group of nominative units along with a category of feminitives resulted from a long history of the vernacular-based Ukrainian literary language development in which vernacular served as a platform for atrend towardmasculine and feminine derivative counterparts. The evidence ofthe slow development of this lexicalsemantic subgroup conditioned by linguistic and extralinguistic factorsis attested from the early historic period. The article examines its operationat each historical stage separately, especially at the contemporary one which is characterized by the increase of female profession names derived from male profession names and the use of such forms in various styles of Ukrainian. The historical development resulted in intense and extensive phenomena with respect to feminitives. The outcome of intensification implies changes proceeding from one stage to another partially supplemented at a certain point, whereas the outcome of extensification meanschanges introduced to the lexical and word-forming structuresand functional features of feminitives in each synchronous section. These phenomenalargely occur during the period of active modern feminization of the Ukrainian language. The formation of female medical activity shows a relatively high ranking of extensivity over intensity. Thispresents dynamic and progressive manifestations in the female profession names formation. Keywords: history of the Ukrainian language, diachrony and synchrony, intensification and extensification, contemporary feminization, female profession names after the medical activity
Verbalization of opposition to Soviet ideology in the discourses of I. O. Svitlychnyi and N. O. Svitlychnа
Authors:   National University of Kyiv-Mohyla Academy, Renchka Inna
Published: January 2023

An article is dedicated to subject of anti-totalitarian expressions in the language, which we define as an alternative communicative discourse in conditions of the rule of soviet totalitarian ideology. On Ukrainian territory an alternative discourse was forming in the medium of creative intelligentsia — the members of the national support movement in the second half of the XX century. The specifics of language forms in resistance to totalitarian system, especially in the idiostyle of particular linguistic identity, has not become the subject of research in Ukrainian linguistics yet. Such review is important for understanding the universal system of similar language forms with a description of their mechanisms, means and techniques. The purpose of article is to detection of linguistics forms and means an anti-totalitarian communication in Ukrainian dissident environment, based on Ivan and Nadiia Svitlychni’ epistolary, journalistic, artistic and memoir texts, and making its linguistic description. For this work were used an empirical observation, descriptive and analytical, contextual analysis methods with some elements of biographical analyzing. Factual material analyze gives reason to believe that the communist totalitarian system and the newspeak, as an outfitting of ideological dogmas have triggered the appearance of a language resistance in the environment of Ukrainian dissidents-sixties. Study of the contents of the letters, articles, artistic works and memoirs of Ivan and Nadiia Svitlychni shows the presence of idiostyle features, which we consider as language forms of resistance to the Soviet ideology. There are the parody of the official discourse, introduction of units of the soviet newspeak in the ironic, comic and critical context, deformation of precedent texts of the newspeak — slogans, stable expressions, stamps, cliche, etc., the combination of contrast components for its functional purposes of presentation, application of the Aesopian language and elements of the language game. Lexical units of newspeak were implemented into text for its stylization under totalitarian discourse. This allowed to go around censorship, and at the same time, due to by getting into an unusual context, these units lost a positive connotative color, acquiring the opposite. Deformation of precedent texts caused the destruction of official ideological standards, totalitarian myths, propaganda narratives and exposing true essence of the Soviet system. Further studies perspective lies in the study of language practices other representatives of the Ukrainian resistance movement from the point of view of their opposition to the Soviet ideological discourse. Keywords: Anti-totalitarian language, the Resistance Movement, linguistic forms of resistance, alternative discourse, ironic context, critical context, reception of contrast
Medical Child Welfare Task Force: A Multidisciplinary Approach to Identifying Medical Child Abuse
Authors: Vega Sarah , Nienow Shalon M. , Huang Maria Z. , Stover Laurie Bernard
Published: January 2023

Medical child abuse is a complex form of maltreatment with powerful and long-lasting impacts on the overall health of affected children. The complexity of this condition renders it challenging for clinicians to recognize its presence and intervene appropriately. The failure of medical systems to identify and deescalate care in this form of maltreatment can result in grievous patient harm. Although the medical literature provides limited guidance on how to address these multifaceted cases, several studies advocate for a multidisciplinary approach. Following a severe and chronic case of medical child abuse at our institution, deficits in response became clear within our hospital system. In reaction to these gaps, the Medical Child Welfare Task Force was developed to formalize education and multidisciplinary collaboration around medical child abuse. The support of institutional leadership and the involvement of multiple medical disciplines that commonly encounter these patients was vital to the implementation and long-term success of the endeavor. To facilitate case identification, education was provided to clinicians in a variety of forums. Moreover, we leveraged the electronic medical record to streamline our ability to monitor cases of medical child abuse and communicate the concerns and plan of care to other providers, both within and outside of our health system. A postimplementation survey determined that the establishment of a multidisciplinary team increased provider comfort and skill in identifying and managing cases of suspected medical child abuse.
Some examples of noncentral moderate deviations for sequences of real random variables
Authors: Giuliano Rita , Macci Claudio
Published: January 2023

The term moderate deviations is often used in the literature to mean a class of large deviation principles that, in some sense, fills the gap between a convergence in probability to zero (governed by a large deviation principle) and a weak convergence to a centered normal distribution. In this paper, some examples of classes of large deviation principles of this kind are presented, but the involved random variables converge weakly to Gumbel, exponential and Laplace distributions.
The representation of the 1989 regime change in contemporary Hungarian prose texts
Authors: Bányai Éva
Published: January 2023

A fundamental segment of contemporary Hungarian prose literature has attempted to represent and textually portray the change in political regimes which took place in 1989. The dictatorship, the totalitarian system and the subsequent transition period proved to be excellent raw material; resulting in a very different kind of prose which, when compared to previous representations of Transylvania, elicits attention on the one hand by being distinctly separate from the assumption of an ideological role, and on the other hand by creating the given linguistic and fictional space through continuous transition(s), (inter-ethnic) in-betweenness and the relevance of otherness.

Authors:   Volgograd State University, Zykova Anastasiya
Published: January 2023

Introduction. This work aims to highlight features of the relationship between Church and State in Byzantium in the period from 1341 to 1357, i.e. during the civil wars, through the systematization and typology of source material. Various types of sources are involved in the study. Its relevance is determined by the insufficient coverage of this aspect in domestic and foreign historiography. Methods and materials. The work uses a systematic approach, as well as a deep analysis of written sources. Analysis. Based on the analysis of written sources, we find out the degree of involvement of the patriarchs of Constantinople in the civil wars in the middle of the 14th century, which is defined as 1) the direct participation of the patriarchs in the civil wars; 2) the use of patriarchs for their own purposes by participants of these conflicts; and 3) the covert participation of patriarchs in the conflicts. Results. It turns out that the role that the church played in the political events of this period was quite high.

Authors:   WSB University in Poznań, Ciechanowska Dorota , Kozerska Agnieszka ,   Jan Dlugosz University in Częstochowa
Published: January 2023

Objective: The study aims to determine whether educationally active women present signs of transformative learning in their own experiences of the COVID-19 pandemic. The focus of the study is the relationship between experiencing transformative learning in a pandemic and the sense of loneliness, received social support, sense of life satisfaction and age. Methods: The study was conducted among 258 educationally active women – part-time students, as well as students of the Universities of the Third Age. Age of the surveyed women: from 19 to 87 years. Data were collected using the online test method. A statistical significance of differences was tested with the U Mann-Whitney test and the two proportion z-test. Results: Most of the surveyed women manifested elements of transformative learning in their experience of the pandemic. Those scoring high on the Transformative Learning in a Pandemic Situation scale have had their life satisfaction decrease to a greater extent than those scoring low. The group scoring high on the Transformative Learning in a Pandemic Situation scale is characterised by a higher sense of loneliness. No relationship was found between perceived manifestations of transformative learning and age, social support, place of residence and education. Discussion: The transformative potential of learning can be seen in a pandemic situation. The obtained data provide arguments supporting the supposition that the feeling of loneliness, influencing the lowering of satisfaction from life, is a factor triggering learning and leading to the change of habits of thinking and acting of educationally active women.

Authors:   Matej Bel University, Brozmanová Monika , Kosová Beata ,   Matej Bel University
Published: January 2023

The study deals with the consequences of national testing at the primary school level on the processes of education, teachers’ work in the classroom and the teaching profession. It is based on the international discourse about the consequences of large-scale testing and investigates Slovak teachers’ opinions and measures they have implemented under the influence of testing in their own instruction and school. The research, carried out by the questionnaire method on a sample of 786 (2017) and 940 (2020) respondents, confirms that teachers perceive national testing as too far from instruction and inconsistent with educational standards. They do not believe it can fulfil the set goals, but, on the other hand, because of it, they narrow down instruction to prepare for tests and take measures that do not change the quality of pupil learning.

The subject of the study is preconceptions of pre-primary education children about the selected phenomenon of “learning”. We were interested in whether there are differences in children’s identified preconceptions regarding intellectual abilities. Identifying such a difference could be one indicator of giftedness that could also be useful in early educational diagnostics. The research design was mixed; data were obtained through semi-structured flexible micro-interviews made individually with 39 children. Conclusions of the research investigation point to a difference in cognitive and structural components of children’s identified preconceptions and a difference in terms of their intellectual abilities while confirming the diagnostic potential of children’s preconceptions to reveal giftedness also in children of pre-school age.

The Emotional Contagion Scale (ECS) developed by Dr. Elaine Hatfield, is a self-report measure used to investigate the individual’s susceptibility to catch another person’s emotions and experience the same. The catching of emotions could be conscious or unconscious. The study aims to validate the Emotional Contagion scale on the Indian subcontinent population for future use and application. The original American scale consisted of 15 items to be responded to by selecting the suitable option from given five, was given to an Indian sample of 498 individuals. To check the validity, Confirmatory Factor Analysis (CFA) was performed. Gender differences were assessed and it was observed that men were high on catching and experiencing the emotions of others as compared to women. The Indian sample on ECS shows moderate to high reliability and high content validity. It thus concludes that the Emotional Contagion scale is valid for future use on the Indian Population.
Do Korean Women Should Work to Make the Marital Relationship Equal? Logistic Regression of Models on Data from the Korean Longitudinal Survey on Women and Families
Authors:   University of Silesia in Katowice, Juszczyk-Frelkiewicz Katarzyna
Published: January 2023

South Korea is a country where gender inequality has been observed from the past to the present. Many studies point out that gender inequality in Korean society is a consequence of Confucianism which still exists in the social norms, structure and hierarchy of society and the mentality of contemporary Korean people. It causes that gender inequality remains strong not only in the job market but also in the gender division of homework and care work issues, particularly in the sphere of family life. The main object of this paper is to investigate the possibility of making marital relationships equal while women are economically active. To achieve the paper’s main goal, the statistical analysis was carried out with logistic regression on data from the Korean Longitudinal Survey on Women and Families in 2012 and 2020. The results indicated that despite the significant social and economic changes in Korean society, women’s activity in the job market did not introduce a significant change in the division of household duties among men and women, which shows women’s involvement in economic support of the family it does not make any significant changes to the aspect of equality in the relationship.

Published: January 2023

Aim. To study the relationship of socio-demographic factors with lipidlowering therapy in primary health care.

Material and methods. This cross-sectional noncomparative study on the prevalence of hypercholesterolemia (ARGO study) included patients aged ≥0 years who visited primary care physicians and cardiologists in the period 2013-2014 with diagnoses of stable coronary artery disease, hypertension, peripheral artery disease, carotid atherosclerosis, aortic aneurysm or having any type of revascularization or ischemic stroke in history. The study, which was conducted in 59 Russian cities, involved 768 doctors from 217 polyclinics.

Results. The analysis included 18273 patients. Of the total number of patients, 7829 (42,9%) people took statins, while 10421 (57,1%) people did not receive it. The maximum percentage of statin use was in the age group of 70-79 years — 52,12%, and the minimum in the age group of 30-39 years — 13,24% (p<0,001). Most often, statins were taken by people with disabilities — 67,67%, and least often, by working people — 32,59% (p<0,001). In terms of marital status, widowed persons were significantly more likely to take statins, 50,36% (p<0,001); least of all in the group, single persons — 32,29%, while in the group of divorced persons, statins were taken by 37,76%, and in the group of married — 43,07%. According to the education level, patients with secondary professional education are the most adherent to statin treatment — 43,75%, while patients with incomplete secondary education were the least likely to take statins — 41,26% (p<0,054).

Conclusion. Taking into account the socio-demographic factors that a person has when prescribing treatment will help develop a strategy for interacting with the patient and will help improve the quality and effectiveness of therapy in this group of patients.

Published: January 2023

Cardiac involvement in sarcoidosis is difficult to diagnose due to the asymptomatic course in 95% of cases, the inaccessibility and low information content of a heart biopsy, the absence of pathological disorders in routine examination methods or their non-specificity. At the same time, it is cardiac sarcoidosis, along with damage to the nervous system, that is the main cause of mortality in sarcoidosis. Early diagnosis is of decisive importance for preventing complications associated with heart involvement and choosing the right treatment tactics. The positron emission tomography-computed tomography (PET-CT) is a method that can help the doctor in assessing the prevalence of sarcoidosis and verifying latent localizations in patients with a morphologically confirmed disease. The article describes a case of the use of PET/CT for the diagnosis of cardiac sarcoidosis.

Published: January 2023

Surgical interventions, accompanied by a subclavian vein cannulation, are associated with the risk of pneumothorax. Timely detection of this condition reduces the risk of secondary complications. An effective and promising method for the early detection of pneumothorax is lung ultrasound.

Aim. To evaluate the routine bedside use of focused lung ultrasound in the early postoperative period in patients after surgical interventions accompanied by subclavian vein cannulation.

Material and methods. This retrospective analysis of 304 case records of patients after surgical interventions accompanied by subclavian vein cannulation was carried out. Patients underwent lung auscultation, lung ultrasound according to the Bedside Lung Ultrasound in Emergency (BLUE) protocol 1 and 6 hours after surgery, or unscheduled with a saturation decrease <90%, the appearance of shortness of breath and/or chest pain. When pneumothorax signs were detected, patients underwent an emergency chest x-ray, and an elective x-ray was performed 1 day after the intervention.

Results. 304 case records were analyzed, lung ultrasound was performed in 187 (61,5%) men and 117 (38,5%) women. In 8 (2,63%) patients, 1 hour after surgery, an A-profile without lung sliding was detected. In 3 (0,99%) patients, auscultatory breathing weakening was noted, complaints of discomfort and pain during inspiration were noted by 5 (1,64%) patients. In all 8 patients, the diagnosis was confirmed by x-ray. In 5 (1,64%) patients, a mild pneumothorax was detected, which did not require drainage, while 3 patients underwent pleural drainage.

Conclusion. Focused lung ultrasound using the BLUE protocol significantly improves the safety profile of patients after subclavian vein puncture, providing high levels of sensitivity and specificity in detecting pneumothorax.

Published: January 2023

Geopolymers are green and sustainable cementitious materials that are a possible alternative to cement due to lower energy consumption and emissions. Volcanic ash can be used as raw material to prepare geopolymers by alkali activation owing to its high silica and alumina content. However, research on volcanic-ash-based geopolymers is still limited and no consensus on the optimal alkali activator and reaction mechanism has been obtained. This study investigates the effect of alkali activators with different cations on the mechanical properties and microstructure of volcanic-ash-based geopolymers. The flexural and compressive strengths were evaluated. X-ray diffractometry, Fourier transform infrared spectrometry, scanning electron microscopy coupled with energy-dispersive spectroscopy and silicon-29 (29Si) magic-angle spinning nuclear magnetic resonance were used to characterise the microstructural properties. The results showed that the alkali activation effect of sodium hydroxide (NaOH) on volcanic ash was superior to those of lithium hydroxide (LiOH) and potassium hydroxide (KOH), particularly at a concentration of 8 mol/l, with 28-day flexural and compressive strengths of 3.0 and 28.3 MPa, respectively. Microstructural results indicated that the sodium hydroxide-activated geopolymers formed dense, continuous, highly polymerised silica–aluminate gels. This paper provides a proper ratio scheme for activating the volcanic ash from similar deposits and promoting practical applications conducive to sustainable engineering development in the future.

This study is carried out to find novel active drug candidates which can effectively bind to key residues of main protease (Mpro) of SARS-CoV-2. We performed molecular docking of fifty-seven (57) ligands from two classes: vanillylacetone and its derivatives and beta-hydroxy ketone derivatives against Mpro of SARS-CoV-2. We also docked three antiviral drugs as reference/benchmark drugs including remdesivir (RDV), chloroquine (CQ), and hydroxychloroquine (HCQ) against Mpro for comparison of inhibition tendencies of selected ligands. Binding energies of our reference drugs are as: CQ = -5.1 kcal mol-1 (with predicted inhibition constant (Ki pred) = 177 μmol), HCQ = -5.7 kcal mol-1 (Ki pred = 64.07 μmol) and RDV -6.3 kcal mol-1 (Ki pred = 13.95 μmol). We got remarkable results for our docked ligands as 79% of total ligands indicated binding energies better than CQ, 39 % better than both HCQ and CQ, and 19 % better than all reference drugs. More interestingly interaction analysis of eight best-docked ligands showed that they interacted with desired key residues of Mpro. We further selected the four best-docked ligands L1 = -6.6 kcal mol-1 (Ki pred =13.95 μmol), L6 = -7.0 kcal mol-1 (Ki pred = 7.08 μmol), L34 = -6.0 kcal mol-1 (Ki pred = 38.54 μmol), and L50 = -6.6 kcal mol-1 (Ki pred =13.95 umol) for further analysis by quantum chemical study, molecular dynamic (MD) simulations and ADMET analysis. We have also carried out MD-simulations of six more docked ligand L2, L14, L20, L36, L46 and L48 some of which were showing weak binding affinities and some average binding affinities to check their simulation behavior. Their RMSD, RMSF and binding free energy results were also quite satisfying. We believe the current investigation will evoke the scientific community and highlights the potential of selected compounds for potential use as antiviral compounds against Mpro of SARS-CoV-2.
Review of machine learning-based Mineral Resource estimation
Authors: Mahboob M.A. , Celik T. , Genc B.
Published: January 2023

Mineral Resources estimation plays a crucial role in the profitability of the future of mining operations. The conventional geostatistical methods used for grade estimation require expertise, understanding and knowledge of the spatial statistics, resource modelling, geology, mining engineering as well as clean validated data to build accurate block models. However, the geostatistical models are sensitive to changes in data and would have to be rebuilt on newly acquired data with different characteristics, which has proved to be a time-consuming process. Machine learning methods have in recent years been proposed as an alternative to the geostatistical methods to alleviate the problems these might suffer from in Mineral Resource estimation. In this paper, a systematic literature review of machine learning methods used in Mineral Resource estimation is presented. This has been conducted on such studies published during the period 1990 to 2019. The types, performances, and capabilities, of several machine learning methods have been evaluated and compared against each other, and against the conventional geostatistical methods. The results, based on 31 research studies, show that the machine learning-based methods have outperformed the conventional grade estimation modelling methods. The review also shows there is active research on applying machine learning to grade estimation from exploration through to exploitation. Further improvements can be expected if advanced machine learning techniques are to be used.

With depression as a major risk factor for suicide in adolescents, this study examined nicotine dependence from the use of e-cigarettes and depressive symptoms among adolescents.

Methods. The authors conducted a retrospective patient chart review at a pediatric clinic in the Midwestern United States, from May 2021 to September 2021. As a standard practice, the clinic uses the adapted Penn State Nicotine Dependency Index to evaluate its patients’ nicotine dependence from the use of e-cigarettes and the PHQ-9 modified for teens to screen for depressive symptoms of its patients. Data on 69 patients were included in the study. The authors used standard descriptive statistics and an adjusted odds ratio (aOR) to analyze the data on the 69 adolescents. 

Results. The mean age of the adolescents was 17.6 (SD = 2.3), 46.4% (n = 32) were female, and 53.6% (n = 37) were male. More than 88% (n = 61) of the adolescents met criteria for high nicotine dependence from e-cigarette use and 30.4% (21 of 69) of them screened positive for depression. Findings of the mixed model analyses indicated that there was not a statistically significant association between nicotine dependence from e-cigarette use and depressive symptoms (aOR = 1.07; 95% confidence interval, 0.93-1.23; P = .0365).

Conclusions. Our findings show that while a third of the adolescents screened positive for depression and the majority (88%) depended on nicotine from e-cigarettes, there was no association between the outcomes. Future larger multicenter studies are needed to better understand the association between nicotine dependence from e-cigarettes and depressive symptoms as reported in the literature.

Background: The Common Femoral Artery (CFA) is the most frequently used peripheral artery for Trans-catheter aortic valve implantation (TAVI) and Endovascular Aortic Repair (EVAR)/ Thoracic Endovascular Aortic Repair (TEVAR) procedures. CFA access hemostasis could be obtained by manual compression, surgical cut-down, or using arteriotomy closure devices, including ProGlide. Method: During a retrospective cohort study we compared ProGlide with surgical cut-down hemostasis in 225 patients who underwent TAVI or EVAR/TEVAR, including 290 access sites, during a 10 years period in terms of access site complications, procedure length and post-procedural hospitalization duration. Results: The success rate of hemostasis was 100% in the PP device group and 98.3% in the SCD group. The mean Procedure length was significantly shorter in ProGlide device hemostasis and the mean post-procedural hospitalization length had a non-significant difference between the two groups. Access site complications occurred in 21.1% of the ProGlide group and 26% of the SCD group. Conclusion: Perclose ProGlide device is safe and effective for access site closure in procedures that need large sheaths and it is non-inferior to standard surgical cut-down. Training, experience and careful application of the device have significant importance in ensuring successful hemostasis.

The preservation of the environment is one of the highest priorities of the world community. An important role played by «green» technical solutions that combine functionality and reduce the negative impact on the environment. Today, such technical solutions are becoming the subject of active patenting by the world's leading companies and individual authors. This work is devoted to the analysis of «green» patent activity of the countries of the Organization for Economic Cooperation and Development (OECD) in the context of its impact on sustainable development. The authors of the study analyze the form and content of «green» intellectual property (Green IP), as well as their relation-ship with the directions described in the Concept of Sustainable Development. The study presents the indicators of changes in the number of «green» patents calculated by the authors over the course of nineteen years, determines the share of «green» patents in OECD member states, and correlates the obtained values with the Progress Index for Sus-tainable Development Goals. The key areas of patent activity of applicants in this industry identified and proposals made to increase the innovative activity of economic entities.
Directions of Development of Technologies to Reduce Greenhouse Gas Emissions for Climate Change Prevention
Authors:   Siberian State Industrial University, Nagaytsev I.A. , Petrova T.V.
Published: January 2023

Currently there is an intensive change in climatic parameters everywhere, which, as a rule, manifest themselves negatively. In the future, these manifestations will worsen, that will lead to irreversible climate changes. Many countries and their associations have realized already the urgency of combating climate change, in particular, caused by greenhouse gas emissions. To prevent the realization of a negative scenario of climate change, various technologies for reducing greenhouse gas emissions are being developed and implemented. Economically developed countries, mainly the countries of the European Union, and some countries of the Asian-Pacific region pay great attention to this issue. Various technologies have already been developed and implemented to reduce greenhouse gas emissions, such as: carbon dioxide (CO2), methane (CH4), nitrogen oxide (N2O), fluorinated gases. Each gas has its own technology. The most common way to minimize greenhouse gas emissions is to reduce carbon dioxide (CO2) emissions, due to the development of a «green» and low-carbon economy. The article discusses the main sources of greenhouse gas emis-sions and existing technologies for their reduction, implemented and implemented projects within the framework of the climate change agenda.

Due to the usage of microclimate management systems, the use of vertical farming is spreading in world practice. As it allows companies to get more products from a smaller growing area, improve the quality (safety) of products and grow crops all year round, regardless of environmental conditions. This paper presents an analysis of the modern vertical farming industry and assesses the impact of management systems on the development of vertical farming.
Organizational and Economic Mechanism of Tariff Regulation of Natural Monopolies
Authors:   St. Petersburg State University of Economics, Krasnova T.A..
Published: January 2023

The sphere of natural monopolies affects the interests of the economy, both global and national scale. In Russia, this is a large system governed by a single law, which requires significant public costs for its existence and functioning. The peculiarity of such systems is the combination of interrelated and interdependent subsystems united by common goals. Taking into account the fact that the current regulatory organization does not allow forming a single management chain for planning, decision-making and stimulating efficiency for all types of natural monopolies, an organizational and economic mechanism of tariff regulation has been developed, in which it is proposed to use the advantages of digital information processing in the form of a navigator for regulating natural monopolies to obtain reliable information about the regulated entity and reducing the costs for its processing The interaction of key factors and the interaction of their elements is presented. The goal is to improve the quality of regulation and control of the activities of natural monopolies and, as a result, to reduce the public costs of regulation.

Make-to-order production needs flexibility, quality and synchronicity of planning. Numerous types of products and complex control parameters lead to high requirements for safety, stability and continuity of the production process, as well as strict requirements for instant production management. The need for a high reaction rate to changes in the production system, adaptability and traceability, must be ensured by methods of accurate and reliable control and management of production. The most difficulty is the stage of making a schedule for make-to-order multi-nomenclature productions. Existing systems of scheduling are often not connected in real time with the current production process, all this leads to a high level of unfinished orders. It is necessary to take a new look at the existing planning systems and search for an approach with the possibility of analyzing and optimizing the operational and production plan, taking into account the actual implementation of the provided production process. The research is aimed at developing a synchronous scheduling method suitable for a multi-nomenclature make-to-order production with a variable number of products, and designed to reduce order fulfillment time, reduce inventory and improve work efficiency by adapting to fluctuations in production and product life cycle and implementing an optimal production plan.
