Ускладнення методики швидкого хіругічно-асистованого розширення верхньої щелепи: систематизований огляд медичної літератури.
Authors: Vares Yan , Vares Yarema
Published: November 2022

Mетою роботи було складання систематизованого огляду ускладнень, що виникають при проведенні операції швидкого хірургічно-асистованого розширення верхньої щелепи (surgically-assisted rapid maxillary expansion – SARME). На платформі Pubmed ми знайшли 37 статей на вищезгадану тематику, 12 з яких було вилучено з огляду згідно з критеріями виключення. Решту 25 статей було переглянуто та проаналізовано у повному обсязі. Серед основних зворотніх ускладнень SARME найчастіше зустрічалися приєднання інфекції, біль після втручання та кровотечі. Також зустрічалися ускладнення, пов’язані з встановленням дистракторів, ускладнення, що вимагають здійснення вторинних хірургічних втручань, а також ускладнення з боку горбово-крилоподібного з’єднання. Основними незворотніми ускладненнями, що виникають внаслідок проведення SARME, виявились втрата зубів та кісткової тканини альвеолярного гребеня, а також переломи кісток основи черепа. Застосування конусно-променевої комп’ютерної томографії верхньої щелепи та кісток основи черепа для планування операційного втручання може допомогти попередити виникнення більшості можливих ускладнень. З етичних міркувань, ми рекомендуємо лікарям під час проведення SARME зосередити зусилля не на мінімізації інвазивності втручання, а на попередженні ускладнень, оскільки ускладнення SARME в будь-якому випадку можуть потенційно нанести більше шкоди пацієнтові, аніж розширення інвазивності цієї процедури.

Published: November 2022

The paper presents the effects of blend injection and dual injection strategies on mixture formation and combustion of syngas-biogas-hydrogen fueling engine working in the solar-biomass hybrid renewable energy system. The research was performed by simulation method on a retrofitted Honda GX200 spark-ignition engine. The results show that at the end of the compression process, in the case of blend injection of 50% syngas-50% biogas, the fuel-rich zone was positioned on the top of the combustion chamber, whereas in the case of dual injection, this zone was found on the top of the piston. In the case of 50% syngas-50% hydrogen supplied, at the end of the compression process, the fuel-rich area observed on the top of the piston with slightly deflected towards the inlet port in both cases of blend and dual injection. When shifting from blend injection mode to dual injection mode, in the case of 50% syngas-50% biogas fueling engine, the mean temperature of the exhaust gas decreased from 1208 K to 1161 K and the NOx concentration decreased from 1919 ppm to 1288 ppm. In the case of a 50% syngas-50% hydrogen fueling engine, the mean exhaust gas temperature decreases from 1283 K to 1187 K leading to a decrease in NOx concentration from 3268 ppm to 2231 ppm. The dual injection has the advantage of lower NOx emission, whereas the blend injection has the advantage of higher efficiency

Published: November 2022

Antiaris toxicaria Lesch. of the Moraceae family is a tree that grows endemic to Indonesia and has a height of about 20-30 m. This study aimed to screen the phytochemical constituents of leaf, bark and its root. The plant materials were collected from the Samarinda Botanical Garden. Latex of this species in Indonesia is known as a source of blowpipe poison. In other countries Antiaris sp. plant parts (leaves, bark and seeds) are used in ethnobotany practice as raw material for traditional medicine. The leaves, bark and seeds of this plant are used in the treatment of syphilis, leprosy, cancer and used as laxatives for sore throats. Screening of the phytochemical constituents of the samples began by tracing the macromolecules of alkaloids, steroids, tannins, phenolic compounds, flavonoids and saponins with various tests. Alkaloids, saponins, tannins, phlobatnins, flavonoids and terpenoids were detected in the chemical analysis. High performance liquid chromatography diode array detection (HPLC-DAD) was conducted. HPLC screening of A. toxicaria extracts revealed the presence of galic acid, catechins, chlorogenic acid, caffeic acid, ellagic acid, epigallocatechin, routine, isoquercitrin, quercitrin, quercetin and kaempferol. The study revealed the array of secondary metabolites present in the plant that can be used in medicinal preparations and will be candidate species for developing a natural insecticide.

In this study, Chenopodium murale Linn. extracts have been evaluated for its in vitro antioxidant, enzyme inhibition, and in vivo neuropharmacological properties in streptozotocin (STZ)-induced memory impairment in rat model. First, the plant was subjected to extraction and fractionation, then quantitative phytochemical analysis was performed to estimate the major phytochemical groups in the extract where high amounts of phenolics and saponins were detected in crude and chloroform extract. The highest total phenolic contents, total flavonoid contents, and total tannin content were also recorded in crude extract and chloroform fraction. The in vitro antioxidant potential of chloroform fraction was high with IC50 value of 41.78 and 67.33 μg/mL against DPPH and ABTS radicals, respectively, followed by ethyl acetate fraction. The chloroform fraction (ChMu-Chf) also exhibited potent activity against glucosidase with IC50 of 89.72 ± 0.88 μg/mL followed by ethyl acetate extract (ChMu-Et; IC50 of 140.20 ± 0.98 μg/mL). ChMu-Chf again exhibited potent activity against acetylcholinesterase (AChE) with IC50 of 68.91 ± 0.87 μg/mL followed by ChMu-Et with IC50 of 78.57 ± 0.95 μg/mL. In vivo memory impairment was assessed using the novel object discrimination task, Y-maze, and passive avoidance task. Ex vivo antioxidant enzyme activities and oxidative stress markers like catalase, superoxide dismutase (SOD), malondialdehyde, and glutathione were quantified, and the AChE activity was also determined in the rat brain. No significant differences were observed amongst all the groups treated with crude, chloroform, and ethyl acetate in comparison with positive control donepezil group in connection to initial latency; whereas, the STZ diabetic group displayed a significant fall in recall and retention capability. The blood glucose level was more potently lowered by chloroform extract. The crude extract also increased the SOD level significantly in the brain of the treated rat by 8.01 ± 0.51 and 8.19 ± 0.39 units/mg at 100 and 200 mg/kg body weight (P < 0.01, n = 6), whereas the chloroform extract increased the SOD level to 9.41 ± 0.40 and 9.72 ± 0.51 units/mg, respectively, at 75 and 150 mg/kg body weight as compared to STZ group. The acetylcholine level was also elevated to greater extent by chloroform fraction that might contain a potential inhibitor of acetylcholinesterase. Treatment with C. murale ameliorated cognitive dysfunction in behavioral study, and provided significant defense from neuronal oxidative stress in the brain of the STZ-induced diabetic rats. Thus C. murale Linn. could be an inspiring plant resource that needs to be further investigated for isolation of potential compounds in pure form and their evaluation as a potent neuropharmacological drug.
Extracellular histones as damage-associated molecular patterns in neuroinflammatory responses
Authors: Richards Christy M. , McRae Seamus A. , Ranger Athena L. , Klegeris Andis
Published: November 2022

The four core histones H2A, H2B, H3, H4, and the linker histone H1 primarily bind DNA and regulate gene expression within the nucleus. Evidence collected mainly from the peripheral tissues illustrates that histones can be released into the extracellular space by activated or damaged cells. In this article, we first summarize the innate immune-modulatory properties of extracellular histones and histone-containing complexes, such as nucleosomes, and neutrophil extracellular traps (NETs), described in peripheral tissues. There, histones act as damage-associated molecular patterns (DAMPs), which are a class of endogenous molecules that trigger immune responses by interacting directly with the cellular membranes and activating pattern recognition receptors (PRRs), such as toll-like receptors (TLR) 2, 4, 9 and the receptor for advanced glycation end-products (RAGE). We then focus on the available evidence implicating extracellular histones as DAMPs of the central nervous system (CNS). It is becoming evident that histones are present in the brain parenchyma after crossing the blood-brain barrier (BBB) or being released by several types of brain cells, including neurons, microglia, and astrocytes. However, studies on the DAMP-like effects of histones on CNS cells are limited. For example, TLR4 is the only known molecular target of CNS extracellular histones and their interactions with other PRRs expressed by brain cells have not been observed. Nevertheless, extracellular histones are implicated in the pathogenesis of a variety of neurological disorders characterized by sterile neuroinflammation; therefore, detailed studies on the role these proteins and their complexes play in these pathologies could identify novel therapeutic targets.

Published: November 2022

The problem of modelling open systems in education, in which non-linear processes take place, requires the use of postnonclassical methodology. Reflection of the reality of pedagogical education which exists in the form of an ecosystem of formal institutions, urban educational formats, educational platforms and communities of practice playing an important role in the development of a future teacher, is possible when building a dynamic model for the development of a professional community and a teacher in it. Research methodology and methods: social constructionism and synergetics as a general scientific methodology of postnonclassical science, analogy, action research, interviews, network analysis, modelling, mathematical description of a model. The purpose of the article is to characterize the application of modelling as a particular methodology in the postnonclassical paradigm of the study of pedagogical education and to propose a prototype of mathematical description of the local (regional) ecosystem of open pedagogical education. The results were obtained during constructing the model in a temporary research team by modelling in action (by the Action Research type) on the local system of engineering and technology education in Krasnoyarsk. Attractors-competences and lead functions have been identified, mathematical coefficients have been developed to track the dynamics of the development in the ecosystem of pedagogical education based on the growth of diversity in the system. In conclusion, specific characteristics of modelling pedagogical education in the postnonclassical paradigm have been highlighted.

The article foregrounds the issue of the development of virtual internationalization on the example of universities in Novosibirsk region. The article focuses on the key trends in the export of Russian higher education. The purpose of the article is to analyze the websites of the universities in Novosibirsk region as a key mechanism for recruiting international students and to develop recommendations for their modernization. Methodology. The study was conducted on the basis of the methodology of the RIAC report “Digital Internationalization: English-language Internet Resources of Russian Universities” (2015), which implies the identification of 10 target groups of potential audience of a university website and 16 semantic blocks filled with specific questions which allow to assess the degree of virtual internationalization. The binary evaluation system (yes/no) enables the formation of a cumulative score and conducting a comparative analysis of universities in the region both in terms of the overall rating and within the semantic blocks. The result of the implementation of this methodology is an analytical report on the features of the virtual internationalization of universities in modern conditions on the example of the Novosibirsk region. The developed recommendations are useful both for the international departments of universities and their administration, and for the regional ministries of education, since they might serve as a basis for developing a strategy for improving the websites of universities and thus favoring the export of higher education in the Russian Federation coming not only from capital universities, but also in the regions. In conclusion, it is admitted that self-positioning of a university in a virtual environment in the context of education export cannot be overestimated, since today the success in increasing the international students’ inflow to the regions of the Russian Federation depends on the virtual internationalization.

A Minimum Error-Based PCA for Improving Classifier Performance in Detecting Financial Fraud
Authors: Pambudi Bayu Nur , Fauziati Silmi , Hidayah Indriana
Published: November 2022

The main challenge of data mining approaches to detect fraud in financial transaction data is the imbalance of data classes in available datasets, with a much smaller fraud class proportion than the non-fraud. This imbalance affects the f1-score to be low due to unbalanced precision and recall. Therefore, the model can predict one class well, but it does not apply to another class. In addition, the lengthy training time duration and high computational resource requirements in implementing data mining also make them a particular concern. Therefore, solely handling imbalanced data is still insufficient to produce the expected performance. Reduction of data dimensions can be a solution to increase the speed of the process. However, this method actually reduces the classifier’s performance when it comes to classification. Furthermore, this study intends to improve the performance of the data mining approach based on the Support Vector Machine (SVM) classifier aiming at detecting financial fraud transactions. The SVM performance was refined by tuning the kernel and hyperparameter integrated with the Random Under Sampling (RUS) and our Minimum error-based Principal Component Analysis (MebPCA). The RUS was used to handle imbalanced data, while MebPCA modified data dimension reduction techniques based on classification errors to speed up computational time without disturbing the performance of SVM. This combination improves the classifier's performance in detecting fraud effectively with a precision improvement of 29.31% and f1-score of 19.8%, and efficiently reduces the duration of training time significantly by 36.39% compared to previous research regarding the SVM method for fraud detection.
Trade-off between Image Quality and Computational Complexity: Image Resizing Perspective
Authors: Setiawan Iwan , Dahlan Rico , Basuki Akbari Indra , Susanto Heru , Rosiyadi Didi
Published: November 2022

This study proposed a new approach for resizing image deal with quality and computational complexity. Here, previous methods in image resizing do analytical works to approximate the original picture element (pixel) or to remove high frequency coefficients. For images with huge pixel, this will result in computational burden due to number of multiplication and addition in the synthesized formula. Instead of the works, this study proposed a new approach in removing the coefficients by exploiting the second-order block matrix without the need to synthesize the formula. It can be called a fully numeric image resizing method. The result shows that the resized version of original image has peak signal to noise ratio (PSNR) equal to 35.24 dB for resizing the famous Lena image which means compareable to the conventional which has PSNR value around 35 dB but here deriving analytical formula is not required. Reducing computational complexity is also achieved as expected with result only 16 addition involved with no multiplication required. This is lower than the conventional in term of computational complexity. Overall, the proposed method has a good balance for both performances than the conventional approaches.
Analysis of Benefits and Barriers Factors in the Implementation of Building Information Modeling (BIM) in Building Construction for Contractor
Authors: Gustian Egi , Milyardi Roi , Lesmana Cindrawaty
Published: November 2022

Abstract. Everywhere in the world, especially as the fourth industrial revolution begins, technological advancements are being discussed. This technological advancement also affects the building industry, one example being the use of Building Information Modeling (BIM) technology. All technologies, particularly BIM, will advance and redevelop throughout this Covid-19 epidemic. BIM has benefits and barriers to implementation that increase with its development and sophistication, particularly for contractors. Therefore, it's important to research the advantages of using BIM as well as the barriers for contractors. The purpose of this study is to analyze the benefits and inhibiting factors in the implementation of BIM in building construction for contractor. This research was conducted by using literature from previous studies to find out what statements are the benefits and barrier factors in the implementation of BIM 4D for contractors with top and middle qualifications. Then the statement was compiled into a questionnaire and distributed to respondents via online platform. In addition to obtaining the mean value for each research variable, the questionnaire survey responses were processed utilizing validity and reliability tests. The findings of this study show that the benefits of BIM implementation for top contractors include better and more appealing building design or modeling, more accurate documentation, as well as better and more attractive building design or modeling for middle contractors. The lack of training and education in BIM itself is the main obstacle to its implementation for these top contractors, while the cost of licensing BIM software or apps is fairly high for midrange contractors.

Published: November 2022

This  article  focuses  at  the issue of strategic communications of Ukraine during the Russian-Ukrainian war, which began on February 24, 2022. The authors consider strategic communications as a system consisting of invariant and variable components that can be projected in media reports. The authors proceed from the fact that, on the one hand, the media are an instrument of strategic communications, and on the other, strategic communications are transformed, reflected in media reports. The study is aimed to reveal the structure of strategic communications, which is characteristic of the period of armed conflict. Reports of the Insider Ukraine Telegram channel during the first 100 days of the war were analyzed. On the basis of a reflexive thematic analysis, using a one-way dispersion analysis, it has been found out that the strategic communications of Ukraine during the war period consist of the following invariant components: interactive communications of Ukraine, operational communications of Ukraine, extraoperational communications of Ukraine, operational and extraoperational communications concerning the RF.

Objective. Analysis of the structural parameters of the perch (Perca fluviatilis L.) population in the Kremenchuk Reservoir in the world of the development of the program of stocking large flat reservoirs of the Dnipro with juveniles of Far Eastern herbivorous fish, there was a need for methodical approaches to reduce the negative impact of small predators on the efficiency of planned stocking. Methodology. Primary materials related to the biology and fishing of perch were collected at the monitoring points of the Institute of Fisheries of the National Academy of Sciences. The basis of this article is the results of our own field research, which was carried out in the entire water area of the Kremenchuk Reservoir during 2016–2021. To determine the composition of catches in nets with different mesh sizes, the refined coefficient of annual commercial mortality was used. Results. The article establishes the general basic population indices of the perch (Perca fluviatilis L.) population in the Kremenchuk Reservoir. Acceptable indices of the perch population and the probability of its negative impact on the stocking of big-headed Chinese carps this year have been established. The scientific novelty of the work is due to the fact that effective stocking is currently possible only in the presence of scientifically based data, which can significantly affect the cost of planting material, and, as a result, the volume of work carried out. These basic principles are able to ensure the sustainable use of aquatic biological resources in natural reservoirs. Practical significance: the biological indices of the P. fluviatilis population presented in this work can be used to calculate the limits for perch commercial fishing in Kremenchuk Reservoir and to assess its negative impact on the stocked young fishes. Key words: perch, Kremenchuk Reservoir, length structure, catch per unit effort, commercial harvest.

Purpose.In the last decade, due to increasing requirements for providing the Ukrainian population with the most valuable dietary food products, the importance of aquaculture has increased significantly. At the same time, an increase in the amounts of cultured fish as well as other agricultural products is possible only through the introduction of highly productive objects of cultivation using economically feasible technologies. Therefore, in today’s conditions, domestic breeders are conducting active selective breeding and scientific work with carp resulting in the approval of the Antoninsko-Zozulenets intrabreed type of the Ukrainian framed and scaly breeds. Findings.The authors of the work reviewed and analyzed the specialized scientific literature on the historical aspects of the development of carp breeding in Ukraine, and the role of the Antoninsko-Zozulenets carp in the selective breeding work. In particular, the genetic composition of scaly and framed carp, the breeding schemes of new intrabreed types, and the proportion of Antoninsko-Zozulenets carp blood in them were analyzed. Practical value.The conducted review of literary sources can be useful for the preparation of lecture material during the educational process of training specialists in the specialty 207 “Aquatic bioresources and aquaculture”, in particular, specialists in ichthyology and zoology. Key words: reproduction, selective breeding, genetics, carp culture, breed, intrabreed type.

Purpose. To determine the main indicators of economic efficiency for artificially obtaining Siberian sturgeon ovulated eggs to the needs of commercial caviar production using brood stocks grown in floating cages in a reservoir with a natural temperature regime of the forest-steppe of Ukraine. Methodology. Calculations were made according to generally accepted methods in economics. For the economic analysis, the actual indicators of economic activity from the SRP “Osetr” LLC enterprise (Kyiv region) in the period 2020-2021 were used. The study was carried out for a fish farm with a capacity of 500 kg of Siberian sturgeon ovulated eggs in fish farm conditions and with the preservation of life of newly matured brood fish in 8+, 9+ and 10+ age groups. The structure of the analysed production costs with an assessment of the company’s profitability indicators provides for the implementation of processes with a full cycle for the cultivation and exploitation of Siberian sturgeon brood stocks with the combined use of modern methods in industrial aquaculture. Findings. In the cost structure of the analysed caviar production, the largest share is wages (30.21%) and costs for the purchase of feeds for different age groups of sturgeon (28.24%). It has been found that for the production of 500 kg of Siberian sturgeon ovulated eggs of brood stock from floating cages in reservoirs with a natural temperature regime and artificial production of mature eggs in recirculation aquaculture systems, the farm’s payback period is at least 10 years. The level of profitability for these type enterprises can exceed 26%. Ways to increase the profitability of these type fish farms with a reduction in the payback period of caviar production have been determined. Originality. For the first time, indicators of the economic efficiency in commercial sturgeon farming with the use of Siberian sturgeon breeding stocks and industrial technologies, which are not common for aquaculture in Ukraine, have been analysed. Practical Value. The study results can be used in the process of industrial aquaculture development and during the evaluation of the results from production activities in commercial caviar farming.
