Abstract:
ZusammenfassungAugmented und insbesondere Virtual Reality-Technologien und -Anwendungen existieren zwar bereits seit einigen Jahrzehnten, durchleben jedoch seit einigen Jahren (erneut) einen Aufschwung, getrieben durch technologische Entwicklungen. Aus diesen Entwicklungen ergeben sich in diversen Branchen, insbesondere aber in der Medienbranche, sowohl vielerlei Chancen als auch Herausforderungen. Vor diesem Hintergrund stellt sich die Frage, wie sich Unternehmen der Medienbranche auf diese neuen Technologien einstellen bzw. eingestellt haben – im Sinne einer strategischen Vorbereitung auf die Zukunft bzw. hinsichtlich ihrer Technologieadoptionsstrategien. In diesem Artikel wird untersucht, wie früh oder spät bzw. zu welchem Zeitpunkt AR- und VR-Investitionen stattfinden und welchen Planungshorizont (Dauer vom Zeitpunkt der Investition bis zum Erreichen des Produktionslevels) Medienunternehmen in ihren AR- und VR-Investitionen verfolgen. Die Ergebnisse zeigen, dass sich diejenigen Medienunternehmen, die in AR und VR investieren, in zwei große Gruppen aufteilen lassen: Wenn investiert wird, geschieht dies entweder relativ früh (nach 2 bis 4 Jahren) oder relativ spät (erst nach 12 bis 14 Jahren) nach Aufkommen der Technologie. Die beiden Gruppen können als Early Majority und Late Majority verstanden werden. Gemeinsam ist allen Medienkonzernen, dass ihre Investitionen einen mittelfristigen Planungshorizont von 5 bis 10 Jahren aufweisen, der bei AR sogar tendenziell länger ist als bei VR. Medienunternehmen sind sich dem langfristigen (Markt‑)Potenzial beider Technologien offenbar bewusst, investieren aber nur sehr zaghaft in diese.

Abstract:
Zusammenfassung. Kognitive Theorien lassen erwarten, daß berufsbezogene computerbasierte Trainings dann effektiv sind, wenn die Trainingsinhalte hohen Praxisbezug aufweisen und das verwendete Feedback hohen Informationsgehalt besitzt. Diese Frage wurde anhand eines 2*2-Versuchsplans mit den Faktoren Praxisbezug und Feedback und 15 erwachsenen Probanden je Zelle untersucht. Die Trainingsinhalte wurden dem industriellen Qualitätsmanagement entnommen, da hier als Folge der ISO 9000 erheblicher Trainingsbedarf besteht. Das Experiment hatte folgenden Ablauf: (1) Tutorial; (2) Vortest; (3) 30-minütige Trainingsphase, je nach Treatment in Form von Beispielen mit hohem vs. niedrigem Praxisbezug, jeweils gefolgt von Feedback mit hohem vs. niedrigem Informationsgehalt; (4) Nachtest. Es zeigte sich, daß höherer Feedback-Informationsgehalt einen größeren Lerngewinn zur Folge hat. Weiterhin interagieren Praxisbezug und Feedback-Informationsgehalt: Hoher Praxisbezug wirkt sich nur dann positiv aus, wenn gleichzeitig auch hoch informatives Feedback gewährleistet ist. Die Ergebnisse werden diskutiert im Hinblick auf ihre Bedeutung für die Gestaltung von Trainings im allgemeinen und CBT-Systemen im besonderen.

Abstract:
The article attempts to present a number of key technologies that determine the new quality of life of people. The following content is specified and disclosed: autonomous artificial intelligence in a smartphone, professional robot assistants, available satellite intelligence, podcasts, digital urban planning tools. In the article, the authors hypothesize that Industry X.0 is by far the highest stage of digitalization and represents a concept of innovative and digital production, the components of which are «smart assets», «smart services», «smart business», and «smart government». Structural elements of the authors’ concept of X.0 Industry are indicated, its visual cut in virtual reality conditions is provided and the functioning of this Industry exclusively within the framework of the 7th technological mode is characterized. The authors have developed and presented the protocol of formation of the X.0 Industry through the prism of innovations, technologies in both the industry sector and business management. 4 stages of implementation of this protocol are defined, namely: determination of the innovative landscape of «technological breakthrough» in a particular industry within the formation of industry X.0; assessment of threats; determining the course of further development and the action plan (four main approaches to which organizations can apply: protection, adoption of innovations, initiation of subversive innovations, retreat); implementation of structural changes at the DNA level of the organization. The authors on the basis of a number of factors bring forward the argument that today’s realities of the digital space require the development of a new logic of running a platform business in terms of its digitization. It is concluded that in practice it is necessary to form a broad coalition of educators, government officials, analysts, high-tech specialists, economists, industrialists, scientists who will join the formation of the X.0 Industry on the basis of digitalization and innovatizing. The authors concluded that Industry X.0 is a new approach to the organization of production in the context of virtual reality, which is based on highly intelligent integrated new products and digital ecosystems that form an innovative digital value chain, add new competencies and implement deep cultural changes in the direction of the formation of a new virtual reality.

Abstract:
The fall of the Soviet empire is traditionally referred to technological problems. However, it is possible to relate this unexpected downfall to degeneration of the Soviet value system, which earlier produced the rise unprecedented in Russian history. Today in society and culture, the main deficiency is in inspiring objectives that can response to the national character and mechanisms of their achievement but not in technologies. The author discusses the ways and prospects of searching these values.

Abstract:
Unalloyed titanium VT10 with a record value of the ultimate tensile strength of 1350 MPa obtained using technologies of selective laser melting and rotary swaging. This value exceeds by 3 times the tensile strength of commercially pure titanium produced using conventional technologies and also exceeds the strength values of Ti6Al4V (grade 5) high strength titanium alloy. The reasons of the increase in the strength characteristics of titanium VT10 are the finedispersed marten site obtained due to high crystallization rates in the process of selective laser melting, and its additional refinement during the rotary swaging process. To study the thermal stability of the mechanical properties of titanium VT10 processed using various technologies, research of the effect of annealing temperature in the range of 100–800 °C on the ultimate tensile strength and elongation to failure were carried out. Results have shown that the dependence of the ultimate tensile strength on the annealing temperature for VT10 titanium samples after selective laser melting and rotary swaging has a threestage behavior. The ultimate tensile strength decrease by 25–35% after heat treatment at 800 °C. The values of elongation to failure for VT10 titanium samples processed by selective laser melting and rotary swaging monotonically increase from 8–12 to 18–23% when the annealing temperature grows up to 800 °C. The possibilities of methods of selective laser melting, rotary swaging and heat treatment to control the mechanical characteristics of titanium VT10, which is a promising material for the manufacture of osteointegrable medical implants, are demonstrated. The combined application of the abovementioned methods makes it possible to produce VT10 titanium with a given combination of strength and plastic characteristics in a wide range of values.

Abstract:
AbstractObjective:To compare the microbicidal activity of low-temperature sterilization technologies (vaporized hydrogen peroxide [VHP], ethylene oxide [ETO], and hydrogen peroxide gas plasma [HPGP]) to steam sterilization in the presence of salt and serum to simulate inadequate precleaning.Methods:Test carriers were inoculated with Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, vancomycin-resistant Enterococcus, Mycobacterium terrae, Bacillus atrophaeus spores, Geobacillus stearothermophilus spores, or Clostridiodes difficile spores in the presence of salt and serum and then subjected to 4 sterilization technologies: steam, ETO, VHP and HPGP.Results:Steam, ETO, and HPGP sterilization techniques were capable of inactivating the test organisms on stainless steel carriers with a failure rate of 0% (0 of 220), 1.9% (6 of 310), and 1.9% (5 of 270), respectively. The failure rate for VHP was 76.3% (206 of 270).Conclusion:Steam sterilization is the most effective and had the largest margin of safety, followed by ETO and HPGP, but VHP showed much less efficacy.

Abstract:
AbstractAbsorption of Pb ion on the (n, 0) carbon nanotube (CNT) (n=4, 5, 6) surface, pure and defected with single vacancy, is investigated based on density functional theory. Pristine (n, 0) CNTs can produce a certain degree of chemical adsorption of Pb ion. While a single vacancy is introduced, the adsorption ability of CNTs for Pb ion increases greatly, and the band gap changes significantly before and after adsorption. SV-(6, 0) CNTs have the strongest adsorption ability, and SV-(5, 0) CNTs are the potential material for the Pb ion detection sensor. It is expected that these could be helpful to the design of Pb filters and sensors.

Abstract:
Sensor technologies can identify modified animal activity indicating changes in health status. This study investigated sheep behavior before and after illness caused by mold-contaminated feed using tri-axial accelerometers. Ten ewes were fitted with HerdDogg biometric accelerometers. Five ewes were concurrently fitted with Axivity AX3 accelerometers. The flock was exposed to mold-contaminated feed following an unexpected ration change, and observed symptomatic ewes were treated with a veterinarian-directed protocol. Accelerometer data were evaluated 4 days before exposure (d −4 to −1); the day of ration change (d 0); and 4 days post exposure (d 1 to 4). Herddogg activity index correlated to the variability of minimum and standard deviation of motion intensity monitored by the Axivity accelerometer. Herddogg activity index was lower (p < 0.05) during the mornings (0800 to 1100 h) of days 2 to 4 and the evening of day 1 than days −4 to 0. Symptomatic ewes had lower activity levels in the morning and higher levels at night. After accounting for symptoms, activity levels during days 1 to 4 were lower (p < 0.05) than days −4 to 0 the morning after exposure. Results suggest real-time or near-real time accelerometers have potential to detect illness in ewes.

Abstract:
The improvement of frozen-thawed sperm quality has been mostly approached from the view of cryopreservation protocol optimization in terms of cryoprotectant solutions, freezing-thawing rates and antioxidant supplementation, while the impact of sperm collection frequency remains unknown in rams. In this work, a multiparametric study was carried out in cooled and frozen-thawed semen to evaluate sperm quality after different semen collection frequencies during a month: zero sperm collection (0 CW), four sperm collections per week (4 CW), and ten sperm collections per week (10 CW). Traditional analyses have been applied, in combination with novel technologies related to redox balance. Frozen-thawed semen quality showed a significant decrease (p < 0.05) in 0 CW and 10 CW in comparison to 4 CW, concerning motility and kinetics parameters. However, apoptosis showed a significant increase (p < 0.05) in 10 CW in comparison to 0 CW and 4 CW. The employment methods related to redox balance provided us with the definitive probe to ensure the influence of collection frequency on balance redox after thawing. Specifically, glutathione peroxidase (GPX) and superoxide dismutase (SOD) activity showed a significant decrease (p < 0.05) in 10 CW compared to 0 CW and 4 CW. The characterization of alternative strategies to sperm cryopreservation based on consideration of male sexual regimes, could improve the quality of frozen-thawed sperm.

Abstract:
Abstract Postmortem epidydimal preservation at low temperature (3-4°C), is a way to preserve and recover male genetic material. This effort aims for prolonging male function as sperm source, followed with its utilization in assisted reproductive technologies. This study aimed to observe the quality of sperm form cauda epididymis which preserved at low temperature for consecutive days. Sperm were retrieved from twelve cauda epididymis of Kacang Goat and its qualities namely motility, intact membrane, life/dead, and abnormality (all in %) were evaluated in every 2 days until 0% motility. Data were compared using analysis of variance at a = 0.05. Result shows significant (P<0.05) decrease in motility, intact membrane, and life/dead, but increase in abnormality during observation at day 0, day 2, day 4 and day 6, respectively. At the respective days, motility was 91.33±1.25%; 74.67±3.88%; 28.17±2.25% and 0.33±0.57%, intact membrane was 54.83±1.04%; 39±3.77%; 25.1±3.32% and 14.83±2.75%, life/dead was 55.17±4.01%; 36±3.5%; 24.3±3.25% and 12±2.78%, abnormality was 3.16±0.76%; 4.16±0.76%; 6.16±2.25% and 11±2.17%. According to the study, it is concluded that preserved sperm from cauda epididymis at low temperature shows decrease in quality and its utilization should rely on the quality status to select the most appropriate assisted reproductive technology.

Abstract:
SUMMARYHigh-throughput sequencing technologies now allow for rapid cost-effective surveys of multiple pathogens in many host species including rodents, but it is currently unclear if the organ chosen for screening influences the number and identity of bacteria detected. We used 16S rRNA amplicon sequencing to identify bacterial pathogens in the heart, liver, lungs, kidneys and spleen of 13 water voles (Arvicola terrestris) collected in Franche-Comté, France. We asked if bacterial pathogen assemblages within organs are similar and if all five organs are necessary to detect all of the bacteria present in an individual animal. We identified 24 bacteria representing 17 genera; average bacterial richness for each organ ranged from 1·5 ± 0·4 (mean ± standard error) to 2·5 ± 0·4 bacteria/organ and did not differ significantly between organs. The average bacterial richness when organ assemblages were pooled within animals was 4·7 ± 0·6 bacteria/animal; Operational Taxonomic Unit accumulation analysis indicates that all five organs are required to obtain this. Organ type influences bacterial assemblage composition in a systematic way (PERMANOVA, 999 permutations, pseudo-F4,51 = 1·37, P = 0·001). Our results demonstrate that the number of organs sampled influences the ability to detect bacterial pathogens, which can inform sampling decisions in public health and wildlife ecology.

Abstract:
The effectiveness of guava leaf extract as an inhibitor of St37 carbon steel in a corrosive medium of 3% NaCl had been researched. The concentration of guava leaf extract inhibitor was used 0%. 3%. 5% and 7% with immersion time of 4 and 8 days. Corrosion rate testing was done by weight loss method. The results of the research at each immersion time, showed that the optimum concentration of leaf guava extract to inhibit corrosion is 7% and the longer time immersion resulted in decreasing corrosion rate on St37 carbon steel. The maximum effectiveness of inhibitor occurred at 7% concentration with 8 days immersion time which is 70,12%. Characterization using Scanning Electron Microscopy (SEM) in sample St37-4-7 and St37-8-7 not all surfaces corroded, but on samples St37-4-0 and St37-8-0 almost all samples were corroded. This is reinforced with eds results in which sample St37-8-0 and St37-4-0 have a lower FeO content than sample St37-8-7 and St37-4-7. The X-Ray Diffraction (XRD) result shows that the phase was Fe.

Abstract:
SummaryAim: The purpose of this article is to underline complications in venous surgery during the past 30 years and new ones arising with the introduction of technologies. We also discuss the “natural reduction” of some of these and how to prevent complications.Methods: We have analysed different types of studies on different surgical procedures in the treatment of varicose veins and compared them with own outcomes.Results: Considering all techniques, we have wound infections in 2,3–4 % of cases, cellulitis in 2,6–16 %, lymphatic complications in 1,3–60 %, pain in 2–23 %, neurologic disease including nerve damages, bruising and numbness in 0–50 %, thrombophlebitis in 0,3–20 %, deep vein thrombosis with or without pulmonary embolism in 0–5,7 %, injury of major vessel in 0,17 %, haematoma in 1,3–31 %, oedema in <1–15 %, hyperpigmentation in 3–11 %, ecchymosis in 0,8–9 %, skin burns in 0,2–8 %, erythema in 2–33 % and endothermal heat-induced-thrombosis (HEIT) in 0–7,5 % of cases.Conclusion: Our outcomes confirmed literature results. We conclude that new technologies improve results and reduce complications, as do tumescent anaesthesia, medical stockings, early mobilization and low weight heparin prophylaxis (LMWH) in high risk patients.

Abstract:
The use of new technologies is important for the preservation of guava, especially in reaching long-distance markets, being indispensable to associate storage techniques to increase the durability of fresh fruit. We evaluated the efficiency of edible coatings based on agar and Scenedemus sp. on the quality and post-harvest conservation of 'Paluma' guava. The experiment consisted of a randomized design with four replicates. The treatments (T) were composed of mixing concentrations between agar and Scenedesmus sp.: A: (0% + 0%); B: (0% + 0.5%); C: (0% + 1%); D: (0% + 2%); E: (3% + 0%); F: (3% + 0.5%); G: (4% + 0%) and H: (4% + 0.5%) applied by immersion. At the end of 11 days of storage at 10 °C ± 2ºC and 65% ± 5% RH, the fruit was analyzed. There was a significant effect (P < 0.05) of the coating based on Scenedesmus sp. on the brightness (L*) of the peel and pulp of guava, hue (°h) and chromaticity (C*) of the peel, loss of fresh mass, firmness of the pulp, ascorbic acid, titratable acidity, pH, SS/AT ratio, and total sugars. We observed a lower maturation and maintenance of the post-harvest quality of 'Paluma' guava with the active packages corresponding to treatments F and H. This included the maintenance of the indexes L*, C* and h of peel color, retention in the loss of fresh mass, in the firmness and maintenance of organic acids

Abstract:
This article presents the results of studying the dimensional accuracy of the bases of complete removable prostheses made using a 3D printer and the traditional method. Bases of complete removable prostheses were made using an intraoral laser scanner iTero Cadent (USA) and a 3D printer Asiga Max UV (Australia). To study the dimensional accuracy of the bases of complete removable prostheses, we used the DentalCAD 2.2 Valletta software. The Nonparametric Wilcoxon W-test was used for statistical analysis of the obtained data. We found that the average value of the difference with the standard for bases made using digital technologies is 0.08744±0.0484 mm. The average value of the difference with the standard for bases made by the traditional method is 0.5654±0.1611 mm. Based on these data, we concluded that the bases of complete removable prostheses made using modern digital technologies (intraoral laser scanning and 3D printer) have a higher dimensional accuracy compared to the bases of complete removable prostheses made using the traditional method with a significance level of p<0.05 (Wilcoxon's W-test=0, p=0.031). Keywords: digital technologies in dentistry, digital impressions, intraoral scanner, 3D printing, ExoCAD, complete removable dentures.

Abstract:
AbstractStructural, elastic, and magnetic properties of cobaltites DyBaCo_4O_7 + _ x produced by various technologies and distinguished by oxygen excess x are experimentally studied. It was found that rhombic distortion of the crystal structure of annealed stoichiometric samples with x = 0 results in frustration removal and elastic property anomalies in the T _ N region, caused by cobalt subsystem ordering. At an insignificant oxygen nonstoichiometry, no structural distortions occur in quenched samples, and anomalies in elastic characteristics in the T _ N region smooth and disappear. The studies of DyBaCo_4O_7 + _ x magnetic properties show that the rare-earth (RE) subsystem remains paramagnetic and its contribution exceeds the contribution of the Co-subsystem with strong antiferromagnetic couplings by an order of magnitude. The magnetic susceptibility of the stoichiometric sample does not exhibit an appreciable anomaly at T _ N , since cobalt subsystem ordering is not accompanied by the formation of a noticeable effective field on RE ions.

Abstract:
The analysis in the centralized laboratory is the main model of laboratory diagnosis and monitoring in the conditions of intensive care. However, alternative models of “point-of-care testing” technology are being actively introduced nowadays. This review article presents the analysis of “Point-of-care testing” technologies from the perspective of the intensive care doctor. The main advantages of this monitoring idea include the speed of analysis and the cost of components. Among the disadvantages we can identify ambiguous assessment of the accuracy and objectivity of analyses, additional burden on the staff of resuscitation and intensive care units. Possible ways of resolving disputable issues aimed at improving quality and reproducibility of the analyses are outlined in this work. Despite the fact that currently “Point-of-care testing” technologies cannot replace centralized laboratories, they are steadily occupying a certain niche and are going to play a more important role in diagnosing and monitoring patients in critical condition.

Abstract:
The combination of solar irradiation and Fenton reagent have been used to enhance the biodegradability (BOD5/COD) of chlorophenol wastewater, including 2-chlorophenol (2-CP), 4-chlorophenol (4-CP), and 2,4-dichlorophenol (2,4-DCP). Results showed that the solar photo-Fenton process improved significantly the biodegradability of chlorophenol wastewater. Basically, increasing initial H2O2 dosage was much more beneficial for increasing biodegradability of wastewater than increasing initial Fe2 + dosage. Among the conditions studied, the optimum condition of increasing biodegradability of chlorophenol wastewater was found with a [H2O2]0/[Fe2 + ]0/[chlorophenol]0 ratio of 10.0/0.2/1.0, 10.0/0.3/1.0, and 10.0/0.2/1.0 for 2-CP, 4-CP, and 2,4-DCP, respectively. As a result, the value of BOD5/COD was increased from 0 for untreated solution up to 0.231, 0.248, and 0.193 for 2-CP, 4-CP, and 2,4-DCP, respectively with a 15-min treatment. Under the operation of optimum conditions, the oxidative state of chlorophenol wastewater could be easily controlled into a higher biodegradability stage. The COD and TOC degradation efficiency could be in excess of 90% on the whole as the preoxidized chlorophenol solution was treated by a following batch-type biological unit. In the meanwhile, the microtoxicity of wastewater reduced more than 95%.

Abstract:
Background Over recent years, interest in the development of smart health technologies aimed at supporting independent living for older populations has increased. The integration of innovative technologies, such as the Internet of Things, wearable technologies, artificial intelligence, and ambient-assisted living applications, represents a valuable solution for this scope. Designing such an integrated system requires addressing several aspects (eg, equipment selection, data management, analytics, costs, and users’ needs) and involving different areas of expertise (eg, medical science, service design, biomedical and computer engineering). Objective The objective of this study is 2-fold; we aimed to design the functionalities of a smart health platform addressing 5 chronic conditions prevalent in the older population (ie, hearing loss, cardiovascular diseases, cognitive impairments, mental health problems, and balance disorders) by considering both older adults’ and clinicians’ perspectives and to evaluate the identified smart health platform functionalities with a small group of older adults. Methods Overall, 24 older adults (aged >65 years) and 118 clinicians were interviewed through focus group activities and web-based questionnaires to elicit the smart health platform requirements. Considering the elicited requirements, the main functionalities of smart health platform were designed. Then, a focus group involving 6 older adults was conducted to evaluate the proposed solution in terms of usefulness, credibility, desirability, and learnability. Results Eight main functionalities were identified and assessed—cognitive training and hearing training (usefulness: 6/6, 100%; credibility: 6/6, 100%; desirability: 6/6, 100%; learnability: 6/6, 100%), monitoring of physiological parameters (usefulness: 6/6, 100%; credibility: 6/6, 100%; desirability: 6/6, 100%; learnability: 5/6, 83%), physical training (usefulness: 6/6, 100%; credibility: 6/6, 100%; desirability: 5/6, 83%; learnability: 2/6, 33%), psychoeducational intervention (usefulness: 6/6, 100%; credibility: 6/6, 100%; desirability: 4/6, 67%; learnability: 2/6, 33%), mood monitoring (usefulness: 4/6, 67%; credibility: 4/6, 67%; desirability: 3/6, 50%; learnability: 5/6, 50%), diet plan (usefulness: 5/6, 83%; credibility: 4/6, 67%; desirability: 1/6, 17%; learnability: 2/6, 33%), and environment monitoring and adjustment (usefulness: 1/6, 17%; credibility: 1/6, 17%; desirability: 0/6, 0%; learnability: 0/6, 0%). Most of them were highly appreciated by older participants, with the only exception being environment monitoring and adjustment. The results showed that the proposed functionalities met the needs and expectations of users (eg, improved self-management of patients’ disease and enhanced patient safety). However, some aspects need to be addressed (eg, technical and privacy issues). Conclusions The presented smart health platform functionalities seem to be able to meet older adults’ needs and desires to enhance their self-awareness and self-management of their medical condition, encourage healthy and independent living, and provide evidence-based support for clinicians’ decision-making. Further research with a larger and more heterogeneous pool of stakeholders in terms of demographics and clinical conditions is needed to assess system acceptability and overall user experience in free-living conditions.

Abstract:
Porphyridium spp. is a debated family that produces phycoerythrin (PE) for use in multiple industrial applications. We compared the differences in the biochemical composition and phycoerythrin yield of P. cruentum and P. purpureum by conventional and green extraction technologies. The protein content in P. cruentum was 42.90 ±1.84% w/w. The omega-3 fatty acid (FA) was highlighted by eicosapentaenoic acid (EPA, C20:5, ω-3, ~9.74 ± 0.27% FA) and arachidonic acid (ARA, C20:4, ω-6, ~18.02 ± 0.81% FA) represented the major omega-6 fatty acid. Conversely, P. purpureum demonstrated a higher lipid content (17.34 ± 1.35% w/w) and an FA profile more saturated in palmitic (C16:0, 29.01 ± 0.94% FA) and stearic acids (C18:0, 50.02 ± 1.72% FA). Maceration and freeze/thaw were the conventional methods, whereas microwave (MW) and ultrasound (US) served as green procedures for PE extraction under the factorial-design methodology. Aqueous solvents, extraction-time and power were the main factors in the statistical extraction designs based on Response-Surface Methodology (RSM). Overall, the PE extraction yield was higher (2-to 6-fold) in P. cruentum than in P. purpureum. Moreover, green technologies (US > MW) improved the PE recovery in comparison with the conventional methods for both of the microalgae. The maximum PE yield (33.85 mg/g) was obtained under optimal US conditions (15 min and buffer solvent (PBS)) for P. cruentum. Finally, we proved the biochemical differences between the red microalgae and ratified the advantages of using green extraction for PE because it reduced the processing times and costs and increased the economic and functional-applications of bioactive compounds in the industry.

Abstract:
The modern world is impossible to imagine without computer networks: both local and global; therefore, the issue of network security is becoming increasingly topical. Currently, methods of detecting attacks can be strengthened by using neural networks, which confirms the relevance of the topic. The aim of the study is a comparative analysis of the quality parameters of network attacks using a combined variant consisting of different neural networks. As research methods used: neural network; multilayer perceptron; Kohonen's self-organizing map. The software implementation of the Kohonen self-organizing map is carried out in Python with a wide range of modern standard tools, creation of a multilayer perceptron and a fuzzy network - using Neural Network Toolbox packages, and Fuzzy Logic Toolbox system MatLAB. On the created neural networks separately and on their combined variant researches of parameters of quality of definition of network attacks are carried out. It was determined that the error of the first kind was 11%, 4%, 10% and 0%, the error of the second kind - 7%, 6%, 9% and 6% on the fuzzy network, multilayer perceptron, self-organizing Kohonen map and their combined version, respectively, which proves the feasibility of using the combined option.
