Authors: Polyzopoulou Konstantia , Tsakiridou Helen
Published: August 2019

Nowadays, teaching in a diverse students’ needs environment is a common situation emerged in the school community. In order for all the students to access the good of education and become a part of the school society, it is needed to be acceptable by teachers in the general school, who have to implement an appropriate instruction procedure to meet pupils’ needs successfully. Suitable teaching depends on teachers’ attitudes toward the inclusion of all the students independently and especially for those who show special educational needs. In the current study, participated 373 preschool, primary and secondary educators who teach in the Greek mainstream school. The participants completed the “Attitudes Toward Inclusive Education Scale” [1] [2]. The findings showed that teachers hold reserved attitudes toward the inclusion of students with physical disabilities and academic difficulties, but they hold favorable attitudes for behavior problem and social difficulties students. Comparisons were conducted using other variables, which exert influence on teachers’ attitudes. The results observed show the necessity of establishing supporting services in the school and organizing appropriate training programs in order for the teachers to acquire the theoretical background and skills to implement inclusive practices effectively.

This text summarizes a qualitative research of bibliographical nature that aimed to reflect about the language as social practice, emphasizing the dialogical nature of theoretical contributions, such as Bakhtin (2006, 2010) and Fairclough (2001), as well as considerations of Marx (1845) and other authors who recover conceptions of these theorists, including Fiorin (2011), who presents a retelling, especially of Bakhtinian positions. In the social perspective of language, principles that emanate from historical, social, cultural and ideological spheres articulate, so that the communication process articulates in fact as a tool to promote human interaction. Regarding discourse, there is need to understand the importance of understanding social and cultural changes, what knowing the context of the discursive subject implies and, consequently, to understand a discursive practice. In the perspective of Fairclough (2001), it is essential to critically analyze the transformations that have occurred in society. The language as social practice is evident in the various discourses, as evidenced by the theoretical positions that support this research. In this perspective, the understanding of the world occurs through the dialogical relationship, in which events of the present, past and future are intertwined, which signals that the discursive practices promote changes in contemporary society.

Este artigo consiste em um relato de experiências com dois trabalhos artísticos sobre a diversidade das mulheres na Universidade da Integração Internacional da Lusofonia Afro-Brasileira (UNILAB). Inicialmente, as experiências com pinturas e desenhos em paredes – conhecidos como muralismo – deram-se na ocupação da UNILAB, em 2016, ocasião na qual se realizou uma intervenção artística na sala dos professores. Por incentivo e ajuda de outros estudantes, os autores deste artigo elaboraram seu primeiro painel – que significa, em nossa leitura, o rosto da UNILAB em sua proposta de integração de culturas e diversidades. Por conseguinte, nosso segundo painel surgiu em 2018, em formato de trabalho de conclusão de curso (TCC) da Licenciatura em Sociologia. Sob a perspectiva da luta pela igualdade de gênero, enfatizamos a importância de valorizar e fortalecer politicamente as expressões artísticas feministas em suas lutas e resistências, com vistas a alcançar maior justiça e igualdade social – em sentido contrário a todas as formas de dominação histórica dos homens sobre as mulheres.

Em tempos de cerceamento dos direitos garantidos em lei, desconstrução da educação, censura da arte e desvalorização da cultura pelo atual governo federal, busca-se refletir, à luz de Hannah Arendt (2001), o sentido da co-labor-ação na produção material, a partir de vivências ligadas ao fazer-viver da cerâmica na comunidade quilombola de Conceição das Crioulas, situada no sertão central de Pernambuco. Para tanto, a pesquisa que resulta neste artigo transita entre os movimentos de resistência relacionados à terra e ao feminino, segundo a imaginação material de Gaston Bachelard (2001), para compreender os efeitos de retroativação da co-labor-ação na resistência da comunidade, partindo do modo como a comunidade quilombola de Conceição das Crioulas partilha seu território e movimenta suas práticas. De natureza fenomenológica e abordagem qualitativa, este artigo se fundamenta nos relatos e registros das vivências realizadas no período de julho de 2018 a junho de 2019 e nas narrativas de mestras, mestres e pessoas da localidade. Conclui-se que a ideia de co-labor-ação no fazer-viver da cerâmica do Quilombo de Conceição das Crioulas constitui um sentido de fissura na exclusão e cooptação da produção material pelo sistema hegemônico, se pensada como ação política.

Our time is the time of rapid technological development. The Internet is becoming available to everyone, and it is expanding its influence in various fields. In addition, the number of users who are using the Internet and who are active consumers of different content is increasing. But the rapid development of technology has created new security problems. New types of threats are emerging, attack techniques are improving. Criminals are now trying to find their «victim»not only in the real world, but also in the digital world. So, today special attention is given to the issue of ensuring the user’s information security and user’s security in the digital world. One of the most vulnerable age groups are children. That is why one of the most important issues is the issue of protecting a child in such an environment. This article is devoted to the problem of information security of children and adolescents in our country. The article describes the main problem of the child in such an environment. On one hand, the virtual activity of the child is the key to its successful education. But, on the other hand, there are risks and problems in the digital world, such as access to prohibited content, that can cause harm to the mental health of a child. This article describes vulnerabilities in the information environment of students and educational institutions, as well as ways to counter the described vulnerabilities.
Negative Output Voltage Ripples of Bipolar DC–DC Converter LM27762 near Maximum Input Voltage
Authors: Bityukov V. K. , Mikhnevich N. G. , Petrov V. A.
Published: August 2019

The paper presents the results of studies of the operation of the inverting DC–DC converter with charge pump and LDO, which are part of the combined bipolar secondary power supply LM27762, at the near to maximum input voltage of 5.5 V and an output voltage of –4.9 V. The ripple voltages were measured at various load currents from 10 to 250 mA at the positive pole of the flying capacitor, at the output of the charge pump system and at the output of the microcircuit. It was shown for the first time on the basis of the obtained information that at low load currents up to about 107 mA the charge pump system operates in the burst mode, and at currents greater than 109 mA – in the charge pump mode with a constant frequency. The results do not confirm the information in the documentation on the microcircuit that, at themaximum input voltage of 5.5 V, the charge pump can enter the PWM mode in hot conditions. When working in burst mode, the presence of LDO in the LM27762 chip reduces the ripples of the negative voltage at the output. However, they significantly exceed the values given in the documentation on the chip. During switching to the constant–frequency mode, the level of negative voltage ripples at the output of the microcircuit decreases sharply, but it increases with further increase of the load current and exceeds the values given in the documentation.
Nominal and Actual Values of Inductor and Capacitor Parameters at High Frequencies
Authors: Gurov E. V. , Uvaysov S. S. , Uvaysova A. S. , Uvaysova S. S.
Published: August 2019

Coil inductance and capacitor capacitance depend on overall dimensions, structure, and ambient factors. They do not vary with frequency. Reactive component impedance is determined by inductance or capacitance respectively, if active resistance is not considered. This is true for the frequencies which are significantly lower than the self-resonant frequency of the component. Parasitic parameters contribution increases on approaching the self-resonant frequency. Therefore, the componentʼs actual inductance and actual capacitance on operating frequency are defined. They are provided by manufacturers and differ from the nominal values. The actual values provide more accurate impedance of components near the considered frequency. Significant deviation from the considered frequency can cause impedance mismatch even more than the nominal values can provide. Frequency response of the high-frequency circuits such as analog filters and impedance match networks are determined by components impedance, not the nominal values. Thus, calculated values must be close to the actual values. The purpose of this article is to justify actual values application instead of nominal values.

Published: August 2019

Two types of satellite radio of communication systems are compared: single-beam and multibeam. The problem of summation and redistribution of radio signal powers of communication systems is discussed. The power redistribution of a group of microwave transistor amplifiers between different beams is analyzed. An adder circuit based on bridge quadrature devices is considered in two- and four-ray systems. For two such cases, the scattering matrix of the signal power adder was compiled. On the basis of these two cases it is possible to compose a scattering matrix for the number of summed powers of microwave signals with the number of rays equal to 8, 16 and 32.
Design for Testability of Integrated Circuits and Project Protection Difficulties
Authors: Pevtsov E. Ph. , Demenkova T. A. , Shnyakin A. A.
Published: August 2019

Design solutions of domestic VLSI were obtained as a result of the application of computeraided design tools of a foreign supplier (CAD Synopsys, Cadence Design Systems and Mentor Graphics), based on standard libraries of PDK elements (Project Design KIT) of factories and IC-modules also supplied mainly by foreign companies. As a rule, the developer does not have its own production facilities, using the services provided by foreign factories (fablesscompanies). Due to this fact, relevant are the studies aimed at the development of a complex of measures, excluding the possibility of unauthorized changes into IC, i.e. protection of projects against intentional hardware and technology violations made during the formation of the control information for handing it over to the production facility and/or in case of IC manufacture at the factory. This paper considers this task from the standpoint of the analysis of the methodology of design for testability (DFT), i.e., a complex of measures that provide obtaining solutions at the design stage. The solutions include the verification of the correct performance of the manufactured chip by means of external tests and/or self-testing procedures. It was proposed, inter alia: 1) to analyze the libraries of standard elements used in the project with full disclosure of their specifications; 2) to create nodes with the physical non-cloning function in the projects on the basis of the libraries of standard elements in models and analysis programs; 3) to analyze IP modules used in the project with the maximum disclosure of structure, methods and algorithms for providing test coverings; 4) to provide for the development in projects of special test kits and methods of their generation at the design stage of functions in order to detect malicious nodes and programs both within SoC cores and at the level of system buses; 5) to develop at the design stage and to apply during tests a technique of special hardware measurements of parameters of the manufactured circuits and analysis of their results, inter alia, according to measurements of delays in distribution of signals and/or buses current consumption.

Published: August 2019

A method has been developed for finding the shortest Hamiltonian path in an arbitrary graph based on the rank approach, which provides high efficiency and a significant reduction in the error in solving the problem of organizing the process of managing multiple transactions and queries when they are implemented in network databases. In many cases, existing solutions do not provide the necessary results in terms of access time and accuracy of the found solution. Using the developed method allows minimizing the idle time of computing devices, reducing the volume and time of data transfer from one device to another, increases overall scalability, minimizes data access time, etc. An important advantage of the proposed method is to reduce the number of elementary operations and the number of vectors being processed the queue of the operations of the request, which leads to a significant reduction in time to implement the procedures for the formation of echer di operations in the requests. Methods of graph theory were used in this paper. The effectiveness of the task solution was evaluated using a systems approach, system analysis and the theory of operations research. Processing of experimental data obtained during the work was carried out in accordance with the provisions of mathematical statistics.

Authors: Bilyk V. R. , Grishunin K. A.
Published: August 2019

The recent progress in terahertz time-domain spectroscopy enables the accurate and reliable measurements of dielectric properties in comparison with the traditional far-infrared spectroscopy using an incoherent light source. The broadband THz-TDS is a powerful tool to determine the real and imaginary parts of a complex dielectric constant by the transmission which allows to detect the parameters of the soft modes in ferroelectrics. In this work, the terahertz time-domain spectroscopy was used to investigate the dependence of the complex refractive index of a single-crystal quantum paraelectric strontium titanate in the terahertz frequency range from 0.3 to 2 THz. It was shown that the low-frequency terahertz response of the material is determined by the soft phonon mode TO1. The measured experimental dependences showed a good agreement with the theoretical curves obtained from the analysis of the Lorentz oscillator model for the complex dielectric constant of strontium titanate. The obtained results are necessary for understanding the principle of possibility to manipulate the order parameter in ferroelectric materials and can be used to create energy-efficient memory devices with a speed of recording information close to the theoretical limit.

Magnetic deformation is a change in the size and shape of a sample under the action of a uniform external magnetic field. The study of this effect in various materials provides deep understanding of the nature of magnetic and mechanical interactions. Moreover, magnetic deformation is of great interest from an engineering point of view for designing new devices. In magnetoactive elastomers containing magnetic microparticles in the polymer matrix, a giant deformation is detected under the action of an external magnetic field. The generally accepted methods for measuring magnetic deformation in magnetoactive soft materials are now practically absent. The article describes the installation for the study of the magnetomechanical characteristics of magnetoactive elastomers and demonstrates its experimental capabilities. The installation allows to measure deformations in the range from 0 to 12.5 mm with a resolution of 1 micron. The deformation curves obtained using these installations are required for developing actuators and sensors based on magnetoactive elastomers, and also for improving their manufacturing technologies.
Symmetrized Maxwell–Garnett Approximation as an Effective Method for Studying Nanocomposites
Authors: Yashin M. M. , Mirzokulov H. B.
Published: August 2019

The symmetrized Maxwell-Garnett (SMG) approximation is considered as the most optimal method of an effective medium for the description of nanocomposite structures. This approximation takes into account the microstructure of the sample, which makes it possible to calculate the metal-dielectric system. Thus, SMG describes with good accuracy the structure of the nanocomposite. Besides, this approximation is applicable for granular alloys consisting of metal components. As a result, this technique can be considered as a universal approximation to describe a wide class of nanostructured materials. At the same time, this article discusses various methods of effective environment. In these methods, the metal component of nanocomposites and the dielectric matrix are replaced by an effective medium with effective permittivity εeff. It is necessary that the particles (granules) in such structures be small in comparison with the wavelength of electromagnetic radiation incident on the sample. Based on this, the spectral dependences of the transverse Kerr effect (TKE) in magnetic nanocomposites were calculated with (CoFeZr)(Al2O3) structure as an example at different concentrations of the magnetic component. The simulation was carried out at small and large concentrations (below and above the percolation threshold). The spectral dependences were obtained taking into account the form factor of nanoparticles and the quasi-classical size effect. Besides, the authors note and discuss in this paper the contribution of various mechanisms that affect the type of spectra of the transverse Kerr effect. Using the symmetrized Maxwell-Garnett approximation, the effective values of the granule size of the nanocomposites under study were found, and the tensor of effective dielectric permittivity (TEDP) was calculated. The obtained TEDP values allowed to simulate the spectral dependences of the magneto-optical transverse Kerr effect. The authors discuss and draw conclusions about the features of the obtained spectral dependences in both the visible and infrared regions of the spectrum. In addition, the practical and fundamental importance of the obtained results is noted. The importance of effective medium methods for the study of optical, transport and magneto-optical properties of magnetic nanocomposites is shown.

Authors: Ky Nguyen Vu
Published: August 2019

After World War II, a part of Japanese soldiers stayed behind in Vietnam and joined the Viet Minh army. They later became known as the ``New Vietnamese'' Japanese and formed an alliance with the Vietnamese against the French. Research on the activities of ``New Vietnamese'' Japanese during the period from 1945 to 1954 plays a very important role in explaining comprehensively and thoroughly the relationship between Vietnam and Japan, and serves a scientific, practical and humanistic purpose. From the 1990s to early 21st century, there have been numerous works of research mentioning the ``New Vietnamese'' Japanese by domestic and international researchers. In recent years, this subject has once again been brought up in exchange activities between the two countries with the attendance of people-who-lived-back-in-the-days, which has attracted wide attention from the scholars and also the media. Based on newly published data and previous studies, the author aims to restore the panorama of the ``New Vietnamese'' Japanese: the number of Japanese people who stayed in Vietnam, the reasons for them to become ``New Vietnamese'' Japanese, and also their activities from 1945 to 1954. Thereby, this research initially evaluates the contributions of the ``New Vietnamese'' Japanese to the Anti-French Resistance War of Vietnamese people.

Penggunaan pompa listrik untuk  kebutuhan air pada umumnya memiliki kekurangan dimana pompa listrik menjadi rusak (terbakar) disebabkan kurang efisiennya penggunaan pompa  yang hidup terus menerus dan tidak terkontrol.   Di dalam penelitian ini penulis akan merancang alat pompa otomatis yang dapat mendeteksi level air, debit air dan dapat proteksi pompa listrik dari kerusakan apabila terjadi arus listrik lebih dan apabila air tidak mengalir dalam waktu tertentu. Dengan adanya alat ini mempermudah manusia untuk mengatur pemakaian air, mengetahui debit air yang masuk ke bak penampungan air dan apabila pompa air tersebut bermasalah, tanpa harus bersusah payah mencari kerusakan karena semua sudah dapat di lihat pada layar lcd. Dari hasil pengujian dapat disimpulkan bahwa alat tersebut sangat berguna untuk mengatur penggunaan air dengan mengatur batas level maksimum dan batas level minimum maka pompa akan hidup dan mati secara otomatis. Dan apabila karena kurang debit air yang mengalir pompa akan mati secara otomatis

The system design test results are obtained that when the sensor detects an object with a certain distance, the  sensor will issue a signal to the micro which is then forwarded to the charging driver circuit to turn on the relay. The relay functions as a switch or switch that will fill the liquid in the bottle, when the driver is charging on, the process of filling the liquid occurs in the bottle, and the micro filling process issues a signal in the active motor driver circuit. The conveyor driver is active after giving a signal from Arduino Uno, the conveyor will stop after the sensor detects a bottle then stops, and the micro sends a signal to turn the motor driver down on the bottle cap to close the bottle on. When the bottle closing process is complete the motor driver backs up actively moving the road conveyor back. The percentage error of theoretical value and measurement of the difference is small and when filling the liquid in a bottle takes 17 seconds until the bottle is fully filled and by using the micro, the liquid filler on the bottle and the bottle cover can be completed properly.

Generator Induksi adalah bagian dari mesin listrik arus bolak balik. Generator arus bolak balik berfungsi mengubah tenaga mekanis menjadi tenaga listrik arus bolak balik. Pada generator Induksi terdapat dua jenis karakteristik yaitu karakteristik beban nol dan berbeban. Karakteristik beban nol adalah karakeristik generator saat tidak ada beban. Sedangkan karakeristik berbeban adalah karakteristik generator saat telah di berikan beban. Karakteristik Beban Nol Meliputi Besarnya Tegangan Terminal, Arus Medan, Dan Fluks Magnetic Yang Di Hasilkan. Generator induksi bekerja dengan penguatan sendiri dengan menggunakan kapasitor. Kapasitor sangat berpengaruh pada karakteristik beban nol, karena kapasitor yang dialiri arus bolak balik akan menghasilkan reaktansi kapasitif, yang akan menghasilkan arus medan. Arus medan yang di hasilkan akan mempengaruhi besarnya tegangan terminal.sehingga pada saat nilai tegangan terminal telah di ketahui maka dapat di buat perhitungan untuk mencari besarnya nilai fluks magnetik.

The role of the power supply device is to produce, process and distribute energy sources. Telecommunication equipment can only operate if it has continuous supply. Therefore, to maintain the continuity of the supply, a UPS (Uninterruptable Power Supply) device system is needed so that the supply to the Essential Load device will remain available so that continuity will be maintained. This research designs and proposes how a series of automatic redundant switch systems on UPS to ensure the availability of power supply for the main equipment of telecommunications systems. The Auto switch circuit is designed to have 3 (three) working stages which will trigger the relay driver as control circuit, namely the normal working condition of the contactor input K1 is present, the input condition is zero (lost), and the input condition is present. This system can automatically supply power to telecommunications equipment.

Escalators or walking stairs are very important for buildings that have more than one or two floors, because if people are going up or down from one floor to another floor is very troublesome and of course it will take a lot of energy when using ordinary stairs. With the escalator or the stairs running is expected to help people to make effective the energy used. Besides that people will not feel tired if you have to go up and down stairs. However, with the development of technology nowadays, ordinary existing escalators are considered to be less efficient, because the escalators continue to work even though the escalators are not used. If this is allowed to continue continuously it is very inefficient and certainly wasteful of energy (electricity). The effect of this waste will not only be felt by the building owner but indirectly can also be felt by the wider community who still need a lot of electrical energy seen from the amount of electricity used to run the escalator stairs.

Paracetamol (acetaminophen) is a widely used over-the-counter analgesic, antipyretic and a mild anti inflammatory drug. In several developing countries some of pharmaceutical industries sale fake, counterfeit and substandard drugs which affect the health of people. The present study investigates the comparison for the quantitative determination of various brands of paracetamol tablet using UV-Visible spectrophotometric, potentiometric and trimetric methods. Four brands (Pacimol, Paracip, Parazest, and Crocin) of paracetamol tablets having 500 mg strength were purchased from various pharmacy shops within Pari chowk and Jagat market in Greater Noida, India. Weight variation test was performed before the assay of paracetamol samples. The result of tablets weight variation (Mean ± S.D) of Crocin, Parazest, Paracip and Pacimol brand was 0.66 ± 0.014, 0.64 ± 0.010, 0.58 ± 0.007 and 0.55 ± 0.009 respectively. All brands showed different mean weight which indicates the use of different excipients in the different brands. The ranges of the amount of paracetamol content (g/tab) for paracetamol samples analyzed using UV-Visible spectrophotometric, potentiometric and trimetric methods were from 0.49195-0.52010, 0.48300-0.52100 and 0.48106-0.50110 respectively. The results indicated that all four brands of paracetamol tablets have sufficient quantity and amount is approximately similar to the company’s recommended or claimed value. Similarly, the ranges of percentage content (assay) of the analyzed samples using UV-Visible spectrophotometric, potentiometric and trimetric methods were from 98.69-104.20%, 96.60-104.20%, and 96.21-100.22% respectively. The assay results indicated that variation among all brands and this may show that different manufacturer formulates the different brands are under the IP specification. However, all of the brands of the tablets under the study were complied with the IP specification and passed for weight variation test and assay conducted on it. Hence, the drug control authority of the government should be continuously monitored the safety, quality, and efficacy of paracetamol tablet through post marketing surveillance practices, and the proper internal quality control of the pharmaceutical companies need to take further necessary steps to ensure the continuity in the establishment of the product quantity and quality.

CORRELATION BETWEEN MEAN PLATELET VOLUME AND IRON DEFICIENCY ANEMIA
Authors: Dagor Himanshu
Published: August 2019

Background: Iron inhibits megakaryopoiesis so iron deficiency anemia (IDA) leads to microthrombosis. Iron therapy ameliorates thrombocytosis. In this study, we investigated whether young, active, and large platelets are released into peripheral blood during iron treatment. Mean platelet volume (MPV) was measured as an indicator for the presence of these platelets.

Materials and Methods: A total of 80 patients (10 males and 70 females) with IDA were included in this retrospective study. IDA was defined as ferritin level <50 ng/mL with a transferrin saturation <20% or ferritin <15 ng/mL. Daily ferrous sulfate (270 mg iron II sulfate and    80 mg of elemental iron) was given orally to patients. We evaluated retrospectively the hematologic and biochemical parameters prior to and 1 month after iron treatment.

Results: the mean ferritin level of the pretreatment group was 6.5 ± 4.0 ng/mL, MPV was

7.9 ± 1.5 fL, hemoglobin (Hb) was 9.8 ± 1.5 g/dL and the mean cellular volume (MCV) was 71.2 ± 7.2 fL. The mean ferritin level of the posttreatment group was 40.3 ± 15.2 ng/mL, MPV was 8.6 ± 2.0 fL, Hb was 12.5 ± 6.6 g/dL, and MCV was 77.6 ± 5.4 fL. The levels of ferritin (P < 0.001), MPV (P < 0.001), MCV (P < 0.001), and Hb (P < 0.001) were significantly higher in the posttreatment group compared to the pretreatment group.

Conclusion: There may be an increase in thrombotic events due to hypercoagulability related to microthrombosis during IDA. Even though thrombosis is corrected during iron treatment, the therapy increases the release of large and active thrombocytes into the peripheral blood.
