Published: May 2023

Legitimacy of women existences captured diverse and compound through the lens of cultural and social background. In the course of history, American Indigenous Women elucidated their identity articulation following the West at the hand of feminism. However, ‘white’ feminism is not in the position to accommodate the unique characteristics of American Indigenous Women. Their social contour and cultural commandment of which giving a rise out of their position and power cried out for suitable paradigm. Indigenous feminism as perspective from and to Indigenous Women would serve to scrutinize women empowerment, aspiration and self-actualization of American Indigenous Women. The article as presented is part of the dissertation analysis within the title Cultural Memory and Demystification of American Native Women’ Position. The analysis of this research is a library based employing the novel from Indigenous female author, Louise Erdrich, entitled The Plague of Dove. In the discussion, the portrayal and representation of certain social and cultural phenomena have been captured and put into consideration as Indigenous Women’s struggle in this modern days. The regulation and also power to determine Indigenous Women’ identity have been strictly limited due to the presence of oppression. The unique of this research laid on the characteristics of the source of oppression in which is in a cooperated linkage within the paradigm employed which is Indigenous feminism. As there are diverse social and traditional elements brought, this research went deep in to the intersectionality studies, focusing on the sexism, racism and colonialism issues predominantly captured as the root of the oppression and discrimination against Indigenous Women.

Authors: Nashiroh Tsalits Syafa'atun , Wahyudi Ribut
Published: May 2023

The mass media opposed Donald Trump for his victory as president in the 2016 U.S election because he was considered involved in exploiting voters’ personal data. This issue was narrated in “The Great Hack” movie. This study attempted to scrutinize propaganda message potential through linguistic and non-linguistic (visual) components in that movie and investigate how both types of components interplayed to create the intended message. The analysis was presented across two axes. First, by using Halliday and Matthiessen’s Systemic Functional Linguistics (SFL), the study primarily focused on the propaganda messages constructed through words, phrases, and clauses. The visual components were analyzed in the second step as complementary analysis. The study found that “The Great Hack” movie wants to construct realities that Donald Trump unfairly gained a victory for the election with Hillary Clinton as a deliberately weakened candidate. In addition, the linguistic and visual components have relations to reinforce and elaborate the intended messages.

Authors: Muhlisin Muhlisin , Sudewi Ni Ketut Nila
Published: May 2023

As the marginalized and minority group in America, Black people’s lives were under the control and influence of White hegemony. This condition affected their social, economic, and cultural activities. This study aims to identify the form of dysfunction in the family, the cause of dysfunction in the family, and the effect on children’s psychology. This study uses a descriptive qualitative method. The researchers use a novel written by Toni Morrison entitled The Bluest Eye as the primary source of data. Additionally, some books, journal articles, and relevant internet sources use as secondary sources. Then, the data was collected and analyzed in several steps. The result shows that the dysfunction in the family is in the form of maltreatment of the family members that are influenced by the pain of the parent’s childhood. It eventually leads to the way how they treat or build relationships with their children and others. The impact of this dysfunctional family on the children is that they become malicious and impulsive, and suffer from a mental disorder or schizophrenia.
Kinship Destruction as a Result of England’s Social Stratification Reflected on George Eliot’s Silas Marner
Authors: Purba Selvia Rosa Magdalena , Rosyidi Mohamad Ikhwan
Published: May 2023

Industrialization in England had a great impact on the life of the world. However, the emergence of stratification sometimes leads society to divisions where conflict is inevitable. The condition let the true human relation be fractured. George Eliot’s Silas Marner portrays the class stratification classes in Warwickshire, England. The aims of this study are to describe kinship destruction as the result of English’s social stratification in George Eliot’s Silas Marner and to explain the reflection of society’s world vision where the author lived on the novel. The method used is the qualitative study and analysed by using Lucien Goldmann’s theory of genetic structuralism. Silas Marner shows that kinship destruction occurred is rooted from differentiation in society. The upper class are described as the one who always benefits and vice versa. Eventually, this is evoked social jealousy and conflicts. Meanwhile, society’s world vision that described is the bad result of social stratification in Warwickshire especially between landed gentry and local farmer. Eliot seemed to convey that social stratification existed is a trigger to a kinship destruction since the differentiations tend to create a conflict among them

Published: May 2023

Description logics are widely used to describe and represent knowledge in the Semantic Web. This is a modern and powerful mechanism that provides the possibility of extracting knowledge from already existing ones. Thanks to this, conceptual of subject areas modeling has become one of the fields of application of descriptive logics, taking into account the use of inference mechanisms. Conceptual modeling is used to create databases and knowledge bases. A key issue of the subject area modeling is the ability to monitor the dynamics of changes in the state of the subject area over time. It is necessary to describe not only the current actual state of the database (knowledge bases), but also the background. Temporal descriptive logics are used to solve this problem. They have the same set of algorithmic problems that are presented in conventional descriptive logics, but to them are added questions related to the description of knowledge in time. This refers to the form of time (continuous or discrete), time structure (moments of time, intervals, chains of intervals), time linearity (linear or branched), domain (present, past, future), the concept of “now”, the method of measurement, etc. An urgent task today is to create an algorithm for the temporal interpretation of conventional descriptive logics. That is, to show a way in which temporal descriptive logic can be applied to ordinary descriptive logic. The paper presents an algorithm for temporal interpretation of LTL into ALC. Linear, unbranched time is chosen for the description goal. It is presented in the form of a whole temporal axis with a given linear order on it. Only the future tense is considered. The algorithm contains graphic notations of LTL application in ALC: concepts, concept constructors, roles, role constructors, TBox and ABox. Numerous examples are used to illustrate the application of the algorithm.

Published: May 2023

The rapid development of the chemical industry and science, and new challenges in the healthcare sector, put forward increased demands for the development of the theory of organic and inorganic chemistry, for the search and implementation of new modeling and analysis methods, and for the improvement of technological processes. One of the main challenges at the intersection of chemistry, physics, biol- ogy, medicine, and genetics is the search for new methods and approaches to the diagnosis and treatment of cancer. A deeper understanding of cancer’s genetics and molecular biology has led to the identification of an increasing number of potential molecular targets that can be used for the discovery and development of anticancer drugs, radiation therapy, etc. One of the main places in this is occupied by molecular modeling. Despite the availability of more and more data on existing proteins and nucleic acids and the availability of modeling methods and tools, the development and use of a wide variety of combined methods and tools for modeling and computing large molecular systems remain an open issue. One of the possible solutions for this problem is the application of the algebraic approach and the corresponding formal methods, which have proven effective in many other fields today. The main idea of the research is the application of algebraic modeling technology and quantum chemical apparatus for modeling and verification of organic chemistry problems, in particular, modeling and analysis of radiation therapy problems. The paper presents the first steps of the research. The example of the formalization of the synchrotron operation principle and the example of the interaction of protons with substance in the example of the determination/calculation of the physically absorbed dose are given in the paper.

In this work we consider comparison of complex information objects (CIO) as a component of intelligent decision-making. The specifics of proposed approach is that we compare not all theoretically possible CIOs but only their subset that is relevant for cur- rent situation and contains existing and available objects. Thus, we find an acceptable solution from the set of available ones that can be not optimal (according to certain criteria). We propose formal ontology-based model of CIO that considered as an element of intellectual information system. This model (in contrast to the domain ontology) defines unique names for positions of classes and class individuals to indicate the SIO structure. The methods of CIO comparison based on the use of knowledge from the relevant do- main ontology are considered. Various approaches to determining of semantic proximity and semantic similarity are considered as metrics for quantitative evaluation to select parameters of information objects that can be used for calculation of these evaluations. We propose an algorithm for semantic comparison of CIOs which are based on the same ontology and have a similar structure. This algorithm allows generation of comparison criteria and determining hierarchy of this criteria for the current situation. We propose to evaluate the semantic-level similarity of the elements of individual CIOs to certain reference CIO defined by the user (as a description of the optimal solution or generated CIO properties). As a result, a subset of CIOs that satisfy the user requirements is cre- ated, but we have to select only one CIO among them, which will be used in the future to fulfill the user task. Therefore, we need in a set of criteria for CIO comparison and methods to determine the importance of each of these criteria at the current moment in time. For this purpose, we propose to use the method of hierarchical analysis based on a pairwise comparison of the importance of individual criteria.

Published: May 2023

The facilities of algebra of hyperschemes are applied for automated generation of neuroevolution algorithms on an example of a binary multiplexer evaluation problem, which is a part of the SharpNEAT system. SharpNEAT is an open-source framework developed in C# programming language, which implements a genetic neuroevolution algorithm for the .NET platform. Neuroevolution is a form of artificial intelligence, which uses evolution algorithms for creating neural networks, parameters, topology, and rules. Evolution algorithms apply mutation, recombination, and selection mechanisms for finding neural networks with behavior that satisfies to conditions of some formally defined problem. In this paper, we demonstrate the use of algebra of algorithms and hyperschemes for the automated generation of evaluation programs for neuroevolution problems. Hyperscheme is a high-level parameterized specification of an algorithm for solving some class of problems. Setting the values of the hyperscheme parameters and further interpretation of a hyperscheme allows obtaining algorithms adapted to specific conditions of their use. Automated construction of hyperschemes and generation of algorithms based on them is implemented in the developed integrated toolkit for design and synthesis of programs. The design of algorithms is based on Glushkov systems of algorithmic algebra. The schemes are built using a dialogue constructor of syntactically correct programs, which consists in descending design of algorithms by detailing the constructions of algorithmic language. The design is represented as an algorithm tree. Based on algorithm schemes, programs in a target programming language are generated. The results of the experiment consisting in executing the generated binary multiplexer evaluating program on a cloud platform are given.

The top-priority challenges were faced by the medical rehabilitation system in Ukraine. Particularly important tasks include, first of all, the rehabilitation of patients who have recovered from COVID-19 disease and people with Combat stress reaction. This fact is well understood both by the society and the leadership of the Ministry of Health of Ukraine, which is creating a special working group on this problem. Ukraine has a system of medical and prophylactic institutions designed for psychological and physical rehabilitation of military personnel; these use modern rehabilitation technologies. However, long-term rehabilitation in such centers is not available to everyone. Therefore, the use of telerehabilitation technology for patients with post-traumatic stress disorder and similar disorders in com- bination with a means of objective control of the functional state is extremely important. One of the most effective solutions in medical rehabilitation assistance is remote patient / person-centered rehabilitation. Rehabilitation also needs effective methods for the "Physical therapist – Patient – Multidisciplinary team" system, including the statistical processing of large volumes of data. Therefore, along with the traditional means of rehabilitation, as part of the "Transdisciplinary intelligent information and analytical system for the rehabilitation processes support in a pandemic (TISP)" in this paper, we introduce and define: the revised and completed basic concepts of the hybrid e-rehabilitation notion and its fundamental foundations; the formalization concept of the new Smart-system for remote support of hybrid e-rehabilitation services and activities; and the methodological foundations for the use of services (UkrVectōrēs and vHealth) of the remote Patient / Person- centered Smart-system. The software implementation of the services of the Smart-system has been developed.

Published: May 2023

The paper focuses on authorization in public clients and provides a secure authorization model as an alternative to costly Microsoft Duende BFF solution. After providing a brief overview of confidential and public clients in terms of authorization, we have analyzed problems and potential attack vectors associated with the authorization process in public clients due to their inability to hold credentials securely. Confidential clients are implemented on secure servers or able to facilitate secure authentication by other means, while public clients lack this security. Our research discovered algorithms, models, and methods for secure authorization in public clients. As a part of our model, we have implemented high entropy Proof Key for Code Exchange generator in C# .NET 6.0. In addition, we have provided a solution to a problem of storing sensitive information in public clients using the Backend for Frontend concept. This concept leverages a reverse proxy pattern where a backend application acts as a proxy and handles all client requests. Having a proxy backend application significantly tightens security model for public clients, while restricting possible attack vectors. The authorization model being researched was based on Proof Key for Code Exchange and Backend for Frontend approach. During the testing phase of our research, we have confirmed that the model was not vulnerable to Cross-Site-Scripting and Auth Code Interception attacks. A sequence diagram outlining main actors and interactions among them in context of authorization has been designed. The diagram stands as the visual representation of the model that uses proposed methods and algorithms. As a result, we have managed to build an alternative to secure authorization solutions for public clients that do not rely on the client secret. We have summarized our key findings in a Blazor Web Assembly application, which is classified as public and uses the described authentication model.

The urgency of the work is determined by the need to transfer confidential information through open communication channels. Such information can be of two types: symmetric encryption keys and directly informational messages that are encrypted with encryption keys. The article deals with the problem of improving the transmission of closed information over open channels using the Diffie- Hellman algorithm. The improvement is due to the introduction of a new type of one-sided function based on the numerical solution of the system of ordinary differential equations describing the dynamics of the phase coordinate movement of the strange attractor. For this purpose, the classic Diffie-Hellman algorithm based on the one-sided function of the discrete logarithm was considered. The required properties of one-sided functions in the general case were considered. Next, the peculiarities of algorithm modification in the case of transition to a one-sided function based on the use of a strange attractor were considered. It is assumed that at the beginning of the operation of the modified algorithm, through a secret channel, the exchange parties (agents) exchange information regarding the properties of the strange attractor to be used, namely, the definition of the differential equations describing the dynamics of a strange attractor, the values of the parameters of the equations, the initial integration conditions and the integration step (for methods with a constant step of integration). After that, all exchanges are conducted exclusively through open channels. The paper also considers the case of information exchange between more than two agents, in particular, the approach of hiding the number of agents participating in the exchange. Approbation of the method is carried out and intermediate and final results of the one-sided function based on strange attractors are given. Possibilities regarding partial disclosure by agents of certain parameters of the use of one-way functions are discussed. But at the same time, the safety of revealing such information is justified in the general case (both in the classical and in the modified Diffie-Hellman method). It was determined that depending on the needs of users, the complexity of the encryption keys can be increased by changing the initial parameters of the attractor, which will also allow controlling speed of key generation and encryption in general. The software that implements the proposed modified algorithm is implemented in three programming languages, C#, Python, and MatLab. This made it possible to perform a comparative analysis of the results and consciously choose the programming language of individual parts of the software to optimize the encryption key generation process for specific conditions.

The article describes applied software of units of such complex hardware-software system, as plants` state monitoring system for application in agriculture and ecological monitoring. The mentioned system consists of data acquisition system in the form of wireless sensor network and adaptive part in the form of decision-making support system. The authors described main applied software of au- tonomous nodes of wireless sensor network and implementation of some program functions of decision-making support system. Wire- less sensor network includes many autonomous wireless sensors, so the main criteria during applied software creation was assuring the energy efficiency of operation of autonomous measuring nodes and network coordinator, and correct interaction of nodes within all network. As it is very difficult to perform testing of applied software of wireless nodes individually in field conditions, it was tested the network cluster, including hardware and software as a whole, in conditions like to applied task. The main parameters, which define the correctness of applied software operation, were estimated. These parameters include, for example, time of network selforganization, distance and quality of stable communication, time of autonomous operation of wireless nodes without charging batteries and so on. To create applied software for the decision-making support system, first of all, methods of plants` state diagnosing and estimating the factors, which influence the plant state, were developed. For this, the field experiments were conducted to determine sufficient dose of herbicide application and estimate the soil moisture using the chlorophyll fluorescence induction method. For processing measured data, several methods of machine learning were used, including neural network approach. Application of machine learning methods made it possible, on the base of acquired data, to make early diagnostics of influence of stress factors on the plant even before the appearance of visual manifestations of such negative influence and determine the decrease of soil moisture through the diagnostics of plant itself, and inform the user about this.

The paper considers a method for assessing the connectivity of nodes of wireless episodic networks (WEN) under the condition of using unmanned aerial vehicles (UAVs). It is proposed to perform an evaluation of the connectivity of a pair of nodes according to a method, which is based on: an evaluation of geometric connectivity, which is limited to the maximum range of radio visibility at the physical level and the vulnerability interval of a given multiple access protocol at the channel level; assessment of information connectivity, which takes into account the presence of not only a physical connection of a given reliability, but also the presence of a free channel resource, a given amount of transmission delay at a given traffic limit value; assessment of the duration of connectivity taking into account the mobility of network nodes. On the basis of analytical mathematical models, the duration of connectivity of mobile subscribers (nodes) (MS) of the WEN consisting of MS and UAVs in direct radio visibility conditions and taking into account relaying was investigated. The connectivity of a pair of nodes is determined by the characteristics of different levels of OSI information interaction, such as radio range, channel bandwidth, information transmission delay, etc. It is shown that the duration of connectivity is directly proportional to the size of the coverage zone and inversely proportional to the speed of movement of nodes. The nature (scenario) of node mobility also affects the duration of connectivity. The simulation of the movement of nodes was carried out under 4 scenarios: «march», «skirmish», «random wandering in the field» and «random wandering in the city». The largest values of the duration of connectivity correspond to the third scenario, and the smallest to the second (with a fixed radius of the coverage area and the speed of movement of nodes). Thus, the average connection duration of the UAV-pedestrian connection in the event of a «difference» will be of the order of 36 minutes, and the UAV-car connection of the order of 5 minutes. The obtained results can be used in the UAV network topology control method.

Published: May 2023

The approach for accuracy assessment of the object model a for the problem of stable grasping in the combined system of the proposal of grasping and the reconstruction of the three-dimensional model of the object was considered. Such a combined system allows stable capture of objects of any shape without restrictions on the types of shapes in the training data set. Novel approaches to surface reconstruction of the object are based on restoring the depth of points from a pair of images from two cameras. The quality of the 3D reconstruction is affected by several factors: the movement of the camera and environmental objects, spatial quantization of the image coordinates, correspondence of key points, camera calibration parameters, unaccounted camera distortions, as well as numerical and statistical properties of the selected reconstruction method. Camera parameter errors can be minimized by improving the calibration procedure, so the impact of errors on the quality of the 3D model was investigated. The deviation of the model from the plane is chosen as a metric for quality assessment. For its calculation, the point cloud is processed by plane identification and segmentation, for which an algorithm based on the RANSAC method is considered. The software package for accuracy estimation was developed. An experiment was conducted to obtain the dependence of the accuracy of the reconstructed planes on the errors of the camera parameters. The impact of calibration errors on 3D reconstruction was evaluated by comparing metrics for individual planes at different levels of artificial error and evaluating the impact of the error on these metrics. Modeling the error of the camera calibration parameters with a given noise level shows that the calibration parameters deteriorate as the noise level increases. In particular, it was established that an increase in error contributes to an increase in the error of estimation of calibration parameters. In addition, orientation parameters (rotation and translation) are more complex and therefore more sensitive to measurement noise than other parameters.
Cloud service for authentication of a person based on their electrocardiogram

Published: May 2023

Telemedicine grows faster with each year. In scope of it new technologies have been created to solve information communication problems. One of them is distance monitoring which requires electrocardiogram analysis. In this case it is important to confirm that the transferred electrocardiogram through information channels belongs to the patient. Researchers from different countries work on this problem. They suggest different methods of authentication by electrocardiogram. The goal of this work is to suggest a prototype of a service that could be used to authenticate electrocardiograms. The paper describes which algorithms have been used to build authentication technology and how it was implemented. There is a short history of built applications. It shows their structures and the purpose. The recently developed system is a prototype to authentication service. It performs registration of new electrocardiograms which is the most time consuming process in authentication. The paper describes the architecture of the system and shows the result of executed experiments. The results show that there is a performance issue with the machine learning library ML.NET. When a lot of cores are allocated to one machine learning instance the overheads highly decrease the overall experiment time. These experiments confirmed Amdahl’s law. Nevertheless, an architecture was found where experiments took the least time for execution. Knowing the issue with the machine learning library, a new architecture setup was suggested and will be implemented in future works. Besides, attention is paid on how developed service should help researchers to improve the technology. The main idea of the system is using one service for developing and testing the technology. That means we can be sure that the cloud service that runs on production would behave the same as in the research phase.

Network effects are determined by the influence of an additional user of a product or service on the value that other users attach to this product or service. Platforms are then defined as entities that connect economic agents, actively managing network effects among the digital copies (images) of those agents. Network effects are distinguished by their sources: such sources can be users of the only group or users of several groups. Because, on a digital platform, network effects are generated jointly by all users, regardless of the groups to which they belong, and interest in the platform increases when the volume of interaction this platform manages increases, it is difficult to distinguish between different sources of network effects. User participation in the platform and their application of platform features can be important because their active evaluation of products and services, together with information provided by user actions (for platforms that collect and apply big data), gives an understanding of those actions, allows providing better services by the platform or adding specific offers. When consumers search for a product, they face travel costs, price information costs, and product feature comparison costs. When suppliers are looking for a willing buyer, they incur travel costs and communication costs regarding their products. Intermediaries reduce transaction costs by centralizing the exchange.

The development of LGBT in Indonesia is getting more and more prominent. LGBT people began to dare to use various ways to show the existence of their group by continuing to exist by organizing various activities, one of which was through organizing a very lively beauty contest specifically for transgender people (waria) both at national and international levels under the name Miss queen. The existence of positive appreciation and praise for the implementation of the contest shows that Indonesian citizens, who are majority adherents of Ahlus Sunnah Wal Jama'ah Islam, are starting to accept this deviant phenomenon. Through a sociological approach, the researcher tries to reveal how Miss queen is from the theological view of Ahlus Sunnah wal Jama'ah. The researcher found that in the theology of Ahlus Sunnah wal Jamaah, it is firmly stated that LGBT is categorized as a despicable act and it is forbidden for its adherents to promote, support, and campaign for LGBT activities, including Miss queen.
