ONLINE RELIABLE FUZZY DATA CLUSTERING USING A SPECIAL TYPE ACCESSORY FUNCTION
Authors: Bodyansky E.V. , Shafronenko A.Yu. , Klimova I. М.
Published: April 2021

An online method of reliable fuzzy clustering is proposed, designed to analyze data sequentially received for processing. A feature of the developed approach is the use of the membership function of a special kind described by the density function of the Cauchy distribution. The actual procedure for clarifying the centroids of clusters is essentially a self-learning rule “The Winner Takes More” (WTM), in which the neighborhood function is generated by the introduced membership function.

Authors: Udovenko S.G. , Kelembet D.B. , Zathei V.A.
Published: April 2021

The features of constructing PDC algorithms - control of nonlinear objects using discrete local TS-models are investigated. The schemes of PDC - regulators with compensation of statistical errors are proposed due to the introduction of digital integrators into the structure of the control system and the subsequent calculation of the regulator coefficients for each of the affine submodels. The results of modeling the considered scheme for control of nonlinear processes are presented. The prospects for using the proposed approach are determined.
CYCLIC PERMUTATIONS IN THE METHODS OF COMBINATORIAL OPTIMIZATION ON THE BASIS OF CYCLIC TRANSFERS
Authors: Grebennik I.V. , Chorna O.S.
Published: April 2021

Permutations sets are very often considered in theoretical and applied research in the field of combinatorics andcombinatorial optimization. By now many properties of permutations have been investigated, in particular those associatedwith the cyclic structure of permutations. To solve optimization problems on combinatorial sets, a number of methodshave been developed and successfully used. Among them, there are methods for finding exact, approximate, and heuristicsolutions. Among the search methods for an approximate solution, search methods in the neighborhood are widely used.Among the combinatorial search methods in the neighborhood, it is necessary to distinguish a group of methods that usescyclic transfers. A general search scheme using cyclic transfers is known. It is based on the search for a cyclic transferin the auxiliary graph. But the features of the tasks being solved sometimes do not allow constructing an auxiliary graphand using the existing search methods. In such cases, an alternative approach is proposed. This is a general strategy forsolving problems using cyclic transfers, which is a modification of the strategy of Thompson and Orlin. We propose theconstruction of cyclic transfers based not on the use of an auxiliary graph, but based on the set of cyclic permutationsand its properties to obtain cyclic transfers. To demonstrate the strategy for solving combinatorial optimization problemsdescribed in the article, one of the vehicle routing problems was solved. Computational experiments were conducted todemonstrate the effectiveness of the proposed strategy. Their results are given in the article.

Authors: Konarieva I. , Pydorenko D. , Turuta O.
Published: April 2021

The given work considers the existing methods of text compression (finding keywords or creating summary) using RAKE, Lex Rank, Luhn, LSA, Text Rank algorithms; image generation; text-to-image and image-to-image translation including GANs (generative adversarial networks). Different types of GANs were described such as StyleGAN, GauGAN, Pix2Pix, CycleGAN, BigGAN, AttnGAN. This work aims to show ways to create illustrations for the text. First, key information should be obtained from the text. Second, this key information should be transformed into images. There were proposed several ways to transform keywords to images: generating images or selecting them from a dataset with further transforming like generating new images based on selected ow combining selected images e.g. with applying style from one image to another. Based on results, possibilities for further improving the quality of image generation were also planned: combining image generation with selecting images from a dataset, limiting topics of image generation.

Optimization and scaling Node.js apps
Authors: Kyrychenko I. V. , Nazarenko A.V. , Popov R. O.
Published: April 2021

The relevance of this work is due to the fact that Node.js is rapidly becoming one of the most popular platforms for building fast, scalable web and mobile applications. In fact, the 2017 Node.js User Survey reveals that there are currently over 7 million Node.js instances online, with three in four users planning to increase their use of Node.js in the next 12 months. And it’s easy to see why: 68 percent of those users say Node.js improves developer productivity, 58 report it reduces development costs, and 50 percent say it increases application performance. As Node.js increasingly becomes the preferred technology for application development, the demand for expert Node.js developers will also continue to increase. The paper considers the problem of scaling and optimization of Node.js applications. Several approaches to developing Node.js applications have been proposed to help optimize code execution speed and develop solutions that are easy to scale.
Method of neural network recognition of falsified images
Authors: Bilotserkovskyy V.V. , Udovenko S.G. , Chala L.E.
Published: April 2021

Methods for generating images falsified using Deepfake technologies and methods for detecting them are considered. A method for detecting falsified images is proposed, based on the joint use of an ensemble of convolutional neural models, the Attention mechanism and a Siamese network learning strategy. The ensembles of models were formed in different ways (using two, three or more components). The result was calculated as the average value of the AUC and LogLoss indices from all the models included in the ensemble. This approach improves the accuracy of convolutional neural network classifiers for detecting static and dynamic images created using Deepfake technologies.
Adaptive Testing Of Knowledge by Methods of Logical Networks
Authors: Shubin I. Yu. , Chetverykov G.G. , Liashyk V.A. , Shanidze N.A.
Published: April 2021

Adaptive test control is a computerized system of scientifically based verification and evaluation of learning outcomes, which is highly effective by optimizing the procedures for generating, presenting and evaluating the results of adaptive tests, based on methods of building and optimizing logical networks. Algorithms for selection and presentation of tasks are based on the principle of feedback, when the correct answer of the subject of training is the next difficult task, and the wrong answer causes the presentation of the next easier task than that to which the subject of training the wrong answer was given. It is also possible to ask additional questions on topics that the subject does not know very well to clarify the level of knowledge in these areas. The choice of testing algorithms is currently actually limited by the forms of presentation of test tasks and algorithms for evaluating test results. Achieving higher results and increasing the motivation to learn is ultimately the main goal of testing knowledge. To determine the basic algorithm, it is necessary to provide a scenario of the system. It is based on the model of taking the exam by a teacher as a model of adaptive testing. This choice of the scenario of the system is due to the fact that, firstly, this procedure is historically well formalized, and secondly, when designing tests, their developer must rely on common, known and used methods with minimal modification.

Published: April 2021

An important feature of the post-quantum period in cryptography is the significant uncertainty regarding the source data for cryptanalysis and counteraction in terms of the capabilities of quantum computers, their mathematical and software, as well as the application of quantum cryptanalysis to existing cryptotransformations and cryptoprotocols. Mathematical methods of digital signature (DS) have been chosen as the main methods of NIST USA, which have undergone significant analysis and substantiation in the process of extensive research by cryptographers and mathematicians at the highest level. They are described in detail and studied at the first stage of the US NIST International Competition. In the second round, a number of decisions were made to merge some candidates for the post-quantum DS standard. 9 candidates were left for further research at the 2nd round: Crystals-Dilithium, Falcon, GeMSS, LUOV, MQDSS, Picnic, qTESLA, Rainbow and SPHINCS+. Three of them (Dilithium, Falcon, qTeSLA) are based on the stability of algebraic lattices (Lattice-based), four (GeMSS, LUOV, MQDSS, Rainbow) are based on multivariate transformations (MQ-transformations), one (SPHINCS+) is based on the stability of hash-function, one (Picnic) is based on the stability of the hash-function and block stream ciphers. During the 2nd round of the US NIST Competition the following finalist algorithms and alternative algorithms were selected as digital signatures according to the results of research on promising post-quantum cryptographic algorithms. As finalists algorithms such DS algorithms as Crystals-Dilithium, Falcon and Rainbow. Alternative algorithms are GeMSS, Picnic and SPHINCS+ were selected. This paper studies the peculiarities of construction of the digital signature algorithm considered as a candidate for the promising post-quantum standard of the NIST PQC competition – Picnic, also it analyzes the protection of the algorithm from known attacks. Data from the comparison of post-quantum algorithms such as digital signature are given. The description of the Picnic algorithm and its parameters are given.
Internal efficiency of public vocational training centres in Kenya
Authors:   Department of Educational Management, Policy and Curriculum Studies, Kenyatta University, P.O. Box 43844 – 00100, Nairobi, Kenya, Okinyi Rachel
Published: April 2021

The efficiency of educational institutions is critical in the justification of resource allocation and use. However, some developing countries like Kenya face efficiency challenges regarding resource utilisation and the flow of students through the school system at various levels of education and programs. Past research in Kenya has focused more on resource utilisation in public schools. Very few studies have looked at the internal efficiency of public vocational training centres (VTCs). This paper assesses the level of internal efficiency in Kenya's public vocational training institutions through a mixed research design. The findings reveal low levels of internal efficiency as indicated by low enrolment, high dropout and low completion rates in the VTC institutions. The result also shows a low level of tutor utilisation. These results provide vital insights into improving the internal efficiency of public vocational training institutions in developing countries. The study recommends, among other things, subsidisation of examination fees to enhance students' completion rates.

Published: April 2021

Hospitalization of Christian leadership as ethical action in the midst of a pandemic is the focus of this study. By looking at the polemic and the crunch that has occurred in the community as a result of the spread of Covid-19, it is very necessary to have an attitude of vitality. Christian leadership hospitality as an ethical action in the midst of the Covid-19 pandemic is a form of ethical attitude to build empathy as an effort to instill human values in the midst of the pandemic. The goal is to instill service motivation based on love as well as an effort to build empathy as an effort to maintain a sense of humanity in the midst of the Covid-19 pandemic through the leadership process. In achieving this study, the method used in this study is the literature method, namely the development of several studies as material contributions in this paper. This study concludes that Christian leadership hospitality as an ethical act in the midst of the Covid-19 pandemic is an implementation of the motivation for loving service which aims to build empathy in society about the importance of maintaining a sense of humanity in undergoing social distancing. Christian leadership hospitality must be viewed as an effort to reveal God's love for this world through a leadership process in the context of a pandemic. Motivation from Christian leadership is a form of hospitality that Christian leaders can expect in taking ethical action in the midst of polemic and in the community about the covid-19 outbreak.Keywords: Hospitalization, Christian Leadership, Ethics, Pandemic, Covid-19.

More than money: The political consequences of reparations
Authors: Voytas Elsa
Published: April 2021

Can material reparations change political participation? I argue that receiving reparations can increase political engagement among survivors of state violence. I examine this claim with content analysis of survivor testimonies, interviews, and causal estimates that leverage exogenous variation in the timing of approving reparations payments addressing the Pinochet dictatorship in Chile. After their reparations claims are approved, surviving victims are more likely to register to vote compared to those yet to receive reparations. I present evidence that the symbolic value of reparations payments holds particular significance for survivors and suggest that they revise their views of the state through this transitional justice experience. These findings indicate that in post-violence contexts, policy experiences can be a consequential determinant of future political behavior, potentially expanding electoral engagement as societies move toward building peace and consolidating democracy.
Differential expression of integral membrane protein 2A in cancers of the breast.
Authors: Mamoor Shahan
Published: April 2021

Breast cancer affects women at relatively high frequency (1). We mined published microarray datasets (2, 3) to determine in an unbiased fashion and at the systems level genes most differentially expressed in the primary tumors of patients with breast cancer. We report here significant differential expression of the gene encoding integral membrane protein 2A, ITM2A, when comparing primary tumors of the breast to the tissue of origin, the normal breast. ITM2A was also differentially expressed in the tumor cells of patients with triple negative breast cancer. ITM2A mRNA was present at significantly lower quantities in tumors of the breast as compared to normal breast tissue. Analysis of human survival data revealed that expression of ITM2A in primary tumors of the breast was correlated with overall survival in patients with basal subtype cancer, demonstrating a relationship between primary tumor expression of a differentially expressed gene and patient survival outcomes influenced by molecular subtype. ITM2A may be of relevance to initiation, maintenance or progression of cancers of the female breast.

Mathematics of Sustainable and Profitable Management of Fisheries Resources
Authors: Vaillant-Tenzer Constantin Igor
Published: April 2021

In this article, it is a question of seeing, from mathematical models, how to optimize the fishery, that is to say, to allow fishermen and women to have maximum gains while preserving the resource. We will see that these objectives are far from being incompatible and even go hand in hand. I study first with biological models, then with bio-economic models, a fishery where only one species is considered exploited. I then propose models of exploitation of several species in trophic interaction by two different approaches: one with systems of coupled differential equations, the other by game theory with a stochastic epidemic model. We will be careful to formulate the assumptions and presuppositions of each model. We will also indicate possible improvements suggested by the literature.
Effective Coping Strategies Employed by University Students in Three Sensitivity Groups: A Quantitative Text Analysis
Authors: Yano Kosuke , Endo Shintaro , Kimura Shunsuke , Oishi Kazuo
Published: April 2021

People differ in their sensitivity to internal and external stimuli, falling into one of three sensitivity groups (low, medium, and high). Studies have pointed out that individual differences in sensitivity should be considered in psychological intervention settings. This study aimed to explore effective coping strategies in the three sensitivity groups. In total, 692 Japanese university students (389 females; Mage = 20.6 ± 1.4 years) responded to an open-ended question about the coping strategies they employ, and to two self-report measures assessing their level of sensitivity and mental health. A series of co-occurrence network analyses with two grouping variables (i.e., better or poorer mental health) suggested that effective coping strategies differed among the three sensitivity groups.
The effects of spatial stability and cue type on spatial learning: Implications for theories of parallel memory systems
Authors: Buckley Matt , Austen Joe , Myles Liam , Smith Shamus , Ihssen Niklas , Lew Adina R. , McGregor Anthony
Published: April 2021

Some theories of spatial learning predict that associative rules apply under only limited circumstances. For example, learning based on a boundary has been claimed to be immune to cue competition effects because boundary information is the basis for the formation of a cognitive map, whilst landmark learning does not involve cognitive mapping. This is referred to as the cue type hypothesis. However, it has also been claimed that cue stability is a prerequisite for the formation of a cognitive map, meaning that whichever cue type was perceived as stable would enter a cognitive map and thus be immune to cue competition, while unstable cues will be subject to cue competition, regardless of cue type. In experiments 1 and 2 we manipulated the stability of boundary and landmark cues when learning the location of two hidden goals. One goal location was constant with respect to the boundary, and the other constant with respect to the landmark cues. For both cue types, the presence of distal orientation cues provided directional information. For half the participants the landmark cues were unstable relative to the boundary and orientation cues, whereas for the remainder of the participants the boundary was unstable relative to landmarks and orientation cues. In a second stage of training, all cues remained stable so that both goal locations could be learned with respect to both landmark and boundary information. According to the cue type hypothesis, boundary information should block learning about landmarks regardless of cue stability. According to the cue stability hypothesis, however, landmarks should block learning about the boundary when the landmarks appear stable relative to the boundary. Regardless of cue type or stability the results showed reciprocal blocking, contrary to both formulations of incidental cognitive mapping. Experiment 3 established that the results of Experiments 1 and 2 could not be explained in terms of difficulty in learning certain locations with respect to different cue types. In a final experiment, following training in which both landmarks and boundary cues signalled two goal locations, a new goal location was established with respect to the landmark cues, before testing with the boundary, which had never been used to define the new goal location. The results of this novel test of the interaction between boundary and landmark cues indicated that new learning with respect to the landmark had a profound effect on navigation with respect to the boundary, counter to the predictions of incidental cognitive mapping of boundaries.

Music is universally prevalent in human society and is a salient component of the lives of young families. Here, we studied the frequency of singing and playing recorded music in the home using surveys of parents with infants (N = 945). We found that most parents sing to their infant on a daily basis, and the frequency of infant-directed singing is unrelated to parents' income or ethnicity. Two reliable individual differences emerged, however: (1) fathers sing less than mothers, and (2) as infants grow older, parents sing less. Moreover, the laer effect of child age was specific to singing and was not reflected in reports of the frequency of playing recorded music. Last, we meta-analyzed reports of the frequency of infant-directed singing and found lile change in its frequency over the last 30 years, despite substantial changes in the technological environment in the home. These findings, consistent with theories of the psychological functions of music, in general, and infant-directed singing, in particular, demonstrate the everyday nature of music in infancy.

Debate continues as to whether an attentional bias towards threat displayed by sufferers of functional gastrointestinal disorders (FGIDs) is conscious and, thus, more amenable to change through psychological therapy. We compared the amplitudes of early (unconscious) and later (conscious) electroencephalographic (EEG) event-related potentials following silent reading of symptom-related, emotionally neutral, and emotionally negative nouns across two participant groups: 30 female FGID-sufferers who met diagnostic criteria for irritable bowel syndrome or functional dyspepsia, and 30 female healthy controls. Analogous indices based on alpha desynchronization were also examined, as were correlations between the EEG-based indices and a range of psychosocial variables. FGID-sufferers displayed marginally significantly higher occipital EPN amplitudes for all nouns, indicating marginally higher levels of unconscious attention in the task. FGID-sufferers also displayed, for negative as compared to neutral nouns, significantly lower central N400 amplitudes indicative of higher conscious attention. The result was only apparent in post-hoc pairwise comparisons, however. Uniquely among FGID-sufferers, central N400 was strongly negatively correlated with a range of negative psychosocial traits and states. The findings provide preliminary evidence of hypervigilance to general (as opposed to symptom-specific) threat among FGID-sufferers. Amidst concerns over Type I error, recommendations are made for fine-tuning the operationalisation of unconscious and conscious attentional bias in this population.
Tell me who you hang out with and I will tell you who you are
Authors: Rubino Valerio
Published: April 2021

This report will revolve around a paper published in 2012 by Saygin, which combines diffusion and functionalimaging to prove that the functionally-defined fusiform face area can be identified by a characteristic pattern ofextrinsic connectivity. As the saying goes: “tell me who you hang out with and I will tell who you are”. First, Iwill briefly review some proposals about the relationship between connectivity and function to unravel therelevance of the study at issue. Then, I will touch some issues related to structural connectivity data analysis and how they have been overcome within a probabilistic framework. Next, I will survey experimentswhich built on the latter and to which Saygin’s added. In the following section, I will describe the methods andresults of Saygin’s article, whose limitations and implications will be then explored in the discussion
A Study of the Implementation of English Program Policy in Secondary Schools under the Secondary Educational Service Area Office 7
Authors: Tran Bhuson , Pa-alisbo Mark Anthony Cenas
Published: April 2021

Recognizing that English skills are vital for international communications, for the economic development of the country, and for Thailand to compete with other nations, the Thai government has formalized the teaching of English in its Basic Education Curriculum. In 1999, the Ministry of Education reformed and decentralized the Thai educational system with the National Education Act B.E. 2542 (A.D. 1999). In 2001, the Ministry of Education issued an English Program Policy allowing qualified schools to teach certain subjects under the Basic Education Curriculum in English as an alternative mode of instruction. This mixed method research investigated the implementation of the English Program Policy of three Secondary Schools under the Secondary Educational Service Area Office 7. Instruments used was opinionnaire surveys adopted from the Office of Basic Education Council (OBEC) English Program Educational Standard Educational Institution Self-Assessment Questionnaire and the English Program/ Mini English Program Implementation Student Questionnaire and selected validated questions from studies by Chantarasiri, and Senachit. Respondents were administrators from the Secondary Educational Service Area 7 Office and from the three selected schools with English Program, and teachers and students from the mentioned schools. The data analysis from this study showed that the level of implementation of the English Policy among administrator was Very High, while the level of implementation among students was High. There was no significant difference in the level of implementation among administrators and teachers, and the study found no significant difference in the level of implementation among teachers when compared by the number of years in the position.
Multielement study in the drainage sediments of a part of Lesser Himalaya, central Nepal
Authors: Jnawali B. M
Published: April 2021

Distribution of different elements from 183 regional stream sediment samples representing 600 Km2 of Chitwan-Dhading Districts (Toposheet 72A/14) has been described. The study of inter-element relationships demonstrated positive correlation among Cu, Pb & Zn. Arsenic Sb & Bi correlations are found to be positive except that Bi & Sb exhibit antipathetic relation, the former showing affinity towards granite in contrast to the latter, which was virtually absent in anomalous amount over granites. A close association of As with Cu, Pb & Zn anomalies suggest that As could be used as a pathfinder for basemetal mineralization.

Regression analysis was used to study the effect of secondary hydroxides of Fe, Mn & Ni on Cu & Zn dispersion, and that of K on Sn & Pb dispersion. The only significant variance explained was Fe on regression of Cu, which was attributed to primary coherence of Cu with Fe probably in chalcopyrite or mafic minerals. The geochemical associations found in stream sediments reflect primary environment and secondary processes in surficial condition modify these very little.
Geotectonics of the Kathmandu Block
Authors: Sharma C. K.
Published: April 2021

To evaluate the geotectonics of the Kathmandu Block on the basis of lithology, stratigraphy and structures, observationsns were made along the two traverses lying east and west of the block. There exist an anticlinorium to the north and a synclinorium to the south of Kathmandu Valley which itself is a faulted anticline. The grade of metamorphism increases towards granites and the Main Central Thrust.
River Terraces along the middle Kali Gandaki and Marsyandi khola central Nepal
Authors: Yamanaka Hidetsugu , Iwata Shuji Iwata
Published: April 2021

River terraces along the middle Kali Gandaki and the Marsyandi Khola are all fill (filltop and fillstrath) terraces, and no strath (rock) terraces are distributed. Three valley-fill deposits are disinguished along the Kali Gandaki and two along the Marsyandi, and some of them are not normal fluvial deposits but mudflow ones in origin. The formative process of terraces along each river was strongly controlled by local and accidental geomorphic events, besides climatic change and other regional factors. Therefore the correlation of terraces between both rivers is very confused. Based on the longitudinal profiles of terraces, the tectonic movement along the middle Kali Gandaki is inferred that the region around Phalebas relatively subsided and the northern and southern regions were comparatively uplifted during the late Quaternary.
