Authors: Karpikova T.S. , Semiletova V.A. , Dorokhov E.V.
Published: December 2021

The study involved 14 volunteer students. Situational anxiety was determined, tests were carried out to determine simple and complex sensorimotor reactions, the cardiac rhythm of the subjects was recorded. Oxygen saturation was determined using an oximeter. Dynamic parameters were recorded: lying in a state of functional rest (background 1), vertical at 65-70° (vertical), lying after verticalization (horizontal), lying in a state of functional rest (background 2). The analysis of the data obtained was carried out using the Excel and StatPlus Pro programs. It was revealed that during verticalization, changes in the regulation of the heart activity of the subjects are carried out mainly due to the central mechanisms of regulation through the sympathetic nervous system. The transfer from a vertical to a horizontal state is accompanied by a restructuring of the regulatory system towards the activation of subcortical nerve centers and a shift in the balance of the SNS/PSNS towards the parasympathetic nervous system.

Key words: passive orthostatic test, cardiac rhythm, simple sensorimotor reaction.

Millions of people around the world suffer from disorders caused by injuries and diseases of the brain and spinal cord. The combination of brain-computer interfaces and neuromodulation technologies is a new approach that could revolutionize the treatment of these disorders. In this study, we tested the effectiveness of a technique in which a patient with a spinal cord injury first undergoes spinal cord stimulation and then participates in a rehabilitation session using a brain-computer interface based on the P300 principle, which decodes visual-motor transformation and uses an assistive robot that moves the patient’s arm, and virtual reality. All healthy participants of the study were able to combine these two techniques without any undesirable effects; studies on patients with spinal cord injury are ongoing. System integration of the two methods has been already performed, and in the future, upon completion of this work, the neural interface will be able to control the stimulation parameters. We propose such integrated systems as a new approach to neurorehabilitation.

Authors: Szilagyi Ana
Published: December 2021

The aim of this paper is to reveal the relationship between the timbre, i.e. sound quality, obtained by an instrumentalist when playing a music piece, and the role of the hearing, listening, and other musical specific mental operations that take place in the brain of the instrumentalist during the performance, with the focus on the classical music, which depends in the most cases on the score. The timbre is a characteristic of every instrument or voice that makes their tone unique. It is given by the different sound components (partials) with different frequencies and amplitudes. The number and the amplitude of the partials are different from instrument to instrument; they depend on the construction of the instrument and on the art of playing, the last being the point in this article. It is known that timbre has an emotional impact on the perception. Its semantic features are represented through descriptors as: dark, bright, round, dull, dry, harsh, etc. that have to be created by the performers, in order to affect the auditory. Thus, they have to possess a good technique, able to get different timbres. Although, the technique has to be subordinated to the capacity of hearing in advance the sound with all its features: pitch, duration, intensity and timbre.

Published: December 2021

Background: Epilepsy disease, which negatively affects 65 million people around the world, can be seen in all age groups regardless of gender. Disease is known throughout the history of human disease, although the mechanism is still unknown. In this study, it is aimed to investigate of apelin and oxidative stress levels in children with epilepsy.

Materials and methods: Children with epilepsy (aged 0-16) who had been diagnosed with epilepsy and did not start treatment were included in the study. This study included control group healthy normal children (n=28) and children with epilepsy group (n=28), totally 56 children were included. Blood samples were removed for apelin, advanced protein oxidation product (AOPP) and DNA damage marker 8-Hydroxy 2-Deoxyguanosine (8-OHdG) levels analyses by ELISA method.

Results: Apelin level in generalized type epilepsy was lower than the control group and the complicated febrile group (p<0.05). It has been found that the number of epilepsy seizures is more common in the generalized type epilepsy (p<0.05). While the number of seizures decreased due to the increase in apelin (p=0.05; r=-0.260), it increased due to the increase in AOPP (p=0.05; r=0.264). AOPP was higher in focal type epilepsy than control group.

Conclusions: Consequently; 1) Apelin reduced the number of seizures by preventing oxidative DNA damage, 2) Increased the number of seizures by the AOPP increase, 3) As the age rises, the number of seizures has been determined to lower due to decreased in AOPP level.

SEISMICITY of the CRIMEAN-BLACK SEA REGION in 2015
Authors: Svidlova V. , Bondar M.
Published: December 2021

In 2015, 58 earthquakes were registered in Crimea in the range of energy classes КП=5.2–10.8. The bulk of the epicenters refers to the Black Sea. The maximum density of epicenters can be traced in Alushta (№ 3) area and in the Kerch-Anapa area (№ 5). Spectral and dynamic parameters of their foci were obtained for 16 events in the region; and for 1 of them a focal mechanism solution was obtained. Seismic processes in the Crimean-Black Sea region were monitored by seven stationary digital seismic stations. In February, the «Tarkhankut» observation point was closed. Representative registration of earthquakes with Кп=9.0 is still provided for main part of the Crimean-Black Sea region. A peculiarity of spatial distribution of earthquakes is the occurrence of two strongest earthquakes in the year under consideration with КП=10.8 in the Kerch-Anapa (№ 5) and Azovo-Kuban (№ 7) areas. The maximum (Кп=10.8, MLWSG=3.8, Mw=3.8) earthquake occurred on August 16 at 22h38m in the Kerch-Anapa region at the depth of h=7 km. This shock caused tremors in Anapa with the intensity of I=2 according the MSK-64 scale. 2015 is characterized by weak seismic activity. The total number of registered earthquakes, ΣN=58, decreased against ΣN=119 in 2014 and is below than the average Nav=69 for the ten-year observation period (2004–2013). The annual seismic energy is ΣE=1.491011J, that is 5.6 times less than the average value ΣEav=8.41011J for the ten-year period. This suggests that we can expect increased seismicity
in the region in subsequent years.

Published: December 2021

Heat light soaking (HLS) has been known to impact the photovoltaic parameters of Cu(In,Ga)Se2 (CIGS) solar cells for a long time. Recently, the focus shifted to the effect of the procedure on alkali fluoride-treated CIGS. Here, we investigate the impact of long-term HLS on the open-circuit (V
OC) loss in high-efficiency CIGS with potassium fluoride (KF) and sodium fluoride (NaF) post-deposition treatment (PDT). HLS is shown to increase the net doping density, however, the subsequent improvement of the V
OC is lower than expected. Using an analysis based on the SQ theory, we show that HLS reduces the nonradiative recombination rate in the bulk but increases the one at the interface. We present a model to explain the increase of interface recombination. We further demonstrate that a combination of HLS and KF/NaF-PDT is necessary to enhance the positive impacts of HLS and mitigate the detrimental ones leading to high-efficiency CIGS devices (22%).

Published: December 2021

This paper discusses the influence of displacement and patterning of phase shifters for piston mode operation of the temperature compensated surface acoustic wave (SAW) resonator on SiO2/LiNbO3 structure. As the phase shifters, Cu metals placed on the top surface of SiO2 are considered. First, the conventional Cu stripes are chosen, and their displacement is considered from interdigital transducer (IDT) aperture edges. It is shown that achievable transverse mode suppression is almost identical when the stripe shape is adjusted for each case. Next, Cu dots are considered as patterned phase shifters. It is shown comparable transverse mode suppression is possible also for this case. However, relatively strong SAW lateral leakage occurs when they are placed above IDT fingers. These results indicate that location and pattern can be added as design parameters for the phase shifters on SiO2. It is favorable for further enhancement of total device performances.
LUPU-Net: a new improvement proposal for encoder-decoder architecture
Authors: ARPACI Saadet Aytaç , VARLI Songül
Published: December 2021

Many network designs in recent years have offered deeper layered solutions. However, models that achieve high-performance results with fewer layers are preferred due to causing less processing load for the system. The U-Net authors succeeded in efficiently creating a model with fewer layers. However, the U-Net architecture also requires improvement to become more efficient. For this purpose, we offer a novel encoder-decoder architecture based on the U-Net and the LU-Net. Furthermore, we propose using a reduced number of up-sampling operations, which were utilized together with the down-sampling operations intensively in the encoder section in our previous research, in the encoder part. The proposed architecture was evaluated on the IOSTAR dataset for the segmentation of retinal vessels. The preprocessing and data augmentation processes were applied to the images before training. The U-Net, LU-Net, and the proposed model were evaluated by using the accuracy, sensitivity, specificity, Dice, and Jaccard metrics. The proposed model achieved performance metric values such as an accuracy of 97.29%, a sensitivity of 81.10%, a specificity of 98.94%, a Dice coefficient of 84.66%, and a Jaccard coefficient of 73.41%. The proposed model obtained improved results compared with the other models, especially for test samples.

Indonesia is the largest producer and the exporter of palm oil in the world which has three palm oil industrial cluster (POIC) areas that are Sei Mangkei (North Sumatera), Dumai (Riau), and Maloy (East Kalimantan). To carry out the delivery of palm oil products to the destination countries, the Palm oil from the three POICs must be transshipment in Malaysia and Singapore. In line with this issues, a strategy to develop the POIC based international connectivity need to be done. This study aims to identify the actual conditions of POIC Indonesia, to determine the factors (internal and external) that influence the development of POIC, and to formulate priority strategy for developing POIC Indonesia. These are needed so that Indonesia can become a hub port of international trade especially in Asia. This research uses "Diamonds" Porter’s Model, gap analysis, and the Analytical Hierarchy Process (AHP). Based on the ana­lysis connectivity, the main strategy that can be formulated in order to develop Indonesian palm oil industry cluster is infrastructure improvements. This strategy can be done if the government (the Ministry of economy, Ministry of industry and trade, Ministry of sea, PT PELINDO, and local government), private sector, academic, and the public is able to work together and integrated.

In my study, I make an attempt to show how the special legal order has changed the regulation of administrative procedure in Hungary. Last year, a record number of decrees were issued in order to regulate the changed life situation as widely as possible. The administration could also not be an exception. In my study, I present the changes through examples. I deal in detail with the legal institution of the public hearing. I chose this because basically, in "peacetime", this legal institution would be inconceivable in practice without the personal presence of the clients, but in the changed life situation, the rules that apply to it cannot be fully applied. I supplement my remarks by supporting statistical data.

Authors: Stefán Ibolya
Published: December 2021

Artificial intelligence has gained more significance in the past few years because of the advanced algorithms, increased data storage and computing power. On the contrary, the novelty has several disadvantages, such as lack of transparency or the possibility of data protection problems. Thereby, there is an urgent need to regulate it properly. As a result of the phenomenon, the European Commission has created a Proposal for a Regulation of the European Parliament and of the Council Laying Down Harmonised Rules on Artificial Intelligence and Amending Certain Union Legislative Act’ in order to protect EU citizens, consumers. The so-called ‘Artificial Intelligence Act’ highlights the importance of consumer protection, as it was established in a previous EU document, the White paper on Artificial Intelligence. This paper aims to examine the regulatory framework of AI on the level of the European Union and to describe the challenges of consumer protection in this new digital era.

Hydro-technical works differ from the other engineering constructions due to the fact that they are subject to water influence. In nature, water exerts mechanical, physical, chemical and biological actions. Water’s mechanical action is expressed by hydrostatic pressure and dynamic pressure. Hydrostatic pressure represents the main stress, which generally determines the form and size of hydro- technical construction. As a rule, dynamic pressure is exerted by water in motion upon the elements it enters into contact. The present paper present with the dimensioning of the pipe segments, focusing on the joining of these and the simulation in conditions as close as possible to reality, of the water pipe, within the help of finite element analysis, but also with specialized simulation software. After analysis, verification and fabrication of the pipe segments, they must be transported and mounted on the inclined plane. The constructive solution of the transport sleigh for the pipes transported on the inclined plane is also verified at requests with the help of the Solid Work software, in order to be able to use it in safe conditions.

Published: December 2021

High sensitivity MEMS pressure sensor chip for
different ranges (1 to 60 kPa) utilizing the novel electrical circuit of
piezosensitive differential amplifier with negative feedback loop (PDA-NFL) is
developed. Pressure sensor chip PDA-NFL utilizes two bipolar-junction
transistors (BJT) with vertical n-p-n type structure (V-NPN) and eight
piezoresistors (p-type). Both theoretical model of sensor response to pressure
and temperature and experimental data are presented. Data confirms the
applicability of theoretical model. Introduction of the amplifier allows for
decreasing chip size while keeping the same sensitivity as a chip with classic
Wheatstone bridge circuit.

Abstract - Diversity is a necessity that cannot be separated from human life. In order to maintain the harmony of life in this diversity, peace must be fought for by all parties, one of which is through peace education. The goal of peace education is to produce people who are wise and able to position themselves through a process of strengthening moderation. This research is based on Johan Galtung's thoughts with his concept of "peace" and "violence" which is a reference for the creation of resolution and post-conflict. This research uses qualitative methods with literature studies through various reference sources, both from books, journals, official websites, and so on. The implementation of Johan Galtung's thoughts in peace education is expected to foster self-discipline and produce individuals who are not only able to interpret peace, create conflict resolution, are able to position themselves in every problem, but also lead to a transformative and lasting peace, without ignoring the presence of violence that will lead to peace. always present as peace is born. This is what is currently needed, especially for the world of journalism which is closely related to the flow and battle of information. With this peace education, it is hoped that a journalist can make decisions to produce journalistic work that is able to reconcile, be balanced, and even become a solution effort to produce transformation and conflict resolution.

Abstrak – Keberagaman merupakan keniscayaan yang tidak bisa dipisahkan dari kehidupan manusia. Guna menjaga keharmonisan hidu dalam keberagaman tersebut, perdamaian harus diperjuangkan semua pihak, salah satunya melalui peace education (pendidikan damai). Tujuan dari peace education melahirkan insan yang bijaksana dan mampu memposisikan diri melalui proses penguatan moderasi. Penelitian ini bertitik tolak pada pemikiran Johan Galtung dengan konsep “peace” dan “violence”-nya yang menjadi rujukan bagi terciptanya resolusi dan pasca konflik. Riset ini menggunakan metode kualitatif dengan studi pustaka melalui berbagai sumber referensi, baik dari buku, jurnal, laman resmi, dan sebagainya. Implementasi pemikiran Johan Galtung dalam peace education ini diharapkan menumbuhkan kebijaksanaan diri dan melahirkan individu yang tidak hanya mampu memaknai kedamaian, menciptakan resolusi konflik, mampu memposisikan diri dalam setiap problematika, tetapi juga membawa ke arah kedamaian yang transformatif dan abadi, tanpa mengabaikan kehadiran kekerasan yang akan selalu hadir seiring perdamaian terlahir. Hal itulah yang saat ini dibutuhkan, terlebih bagi dunia jurnalistik yang erat kaitannya dengan arus dan pertarungan informasi. Dengan peace education ini, diharapkan seorang jurnalis dapat mengambil keputusan untuk menghasilkan karya jurnalistik yang mampu mendamaikan, berimbang, bahkan menjadi upaya solutif untuk menghasilkan transormasi dan resolusi konflik.

Published: December 2021

The article contains material on the princi-ples and special conditions for the function-ing of special economic zones of technology-innovation type. Since the creation of the first free economic zone (FEZ), there have been many changes. There have been both successful projects and weak experiences that have already been analyzed. Regular revision, generalization, and updating are required for many regulations governing the creation and operation of these territories with special conditions. At the same time, potential SEZ residents – entrepreneurs – need an explanation of the complex lan-guage of regulatory acts. This work was based on the generalization of methodologi-cal documents and practical experience. It focuses the reader on the principles and conditions that allow nowadays to create promising, successfully developing SEZs. The paper can become the basis for updat-ing regional and local regulatory acts to im-prove conditions for the advanced develop-ment of territories.

Modern energy systems are at the stage of global transformations affecting the function-ing of industries and spheres of activity. The changes that are taking place are not always positive. For example, the unreliability of re-newable energy in difficult weather condi-tions has led to problems with energy supply to European consumers in 2020–2021. The article shows the feasibility of using the ter-minological and mathematical apparatus of economic synergy for the analysis and fore-casting of indicators of energy systems. In particular, it is proposed to take into account the partial reversibility of evolutionary pro-cesses in the strategic planning of energy development.
